Which is better, forward or reverse rotation of rotary tiller? Which is more suitable for farmland f

There are not many rotary cultivators that are directly reversed, and most of them are straw returning machines or small BMW machines used on the construction site.

First of all, let's talk about the difference between forward rotation and reverse rotation: forward rotation means that when the agricultural machinery is working, the direction of rotation of the cutter shaft is forward, that isand the direction of the tractor;

The reversal refers to the backward rotation of the knife axis, that is, when the tractor is advancing, the knife axis is still rotating backwardsAnd the direction of the tractor is reversed.

So what are the advantages and disadvantages compared to forward and reverse reversals?

Positive**The working load of the tractor is lighter than that of reversal, the operation speed is faster than that of reversal, and the efficiency of farmland is higher, but the effect of soil crushing in farmland is not as good as that of reversal;

Anti**The operating load is much heavier than that of the forward rotation, because the reversed tool axle will give the tractor a reaction force. One force forward, one force backward, quite a tug-of-war with the tractor, at least 30% more power than the forward rotation, that is to say, fuel consumption will be greatly increased.

The general tractor below 50 horsepower, equipped with reversing agricultural machinery, the farmland operation is more difficult, and the loss of the tractor is also relatively large. In some places where the specific resistance of the soil is larger, such as clay soil, it is not recommended to use reversal agricultural machinery, but the biggest advantage and benefit of reversal is that it is better to eliminate stubble and stir in farmland, because the operation speed of the tractor is slow, so the soil and straw can be fully hit, and the crushing effect is better. Especially the small BMW machine that reverses on the construction site, which is used in crawling gear, only advances a few hundred meters per hour, so that it can be fully crushed and stirred to meet the construction requirements.

In fact, in contrast, it can be seen that the reversal of agricultural machinery,It is mainly used in relatively high or special environments, such as straw returning to the field, which requires a high degree of soil crushing, and all the straw needs to be buried under the soil.

ButConsidering the cost and efficiency, the normal cultivation of the general farmland can be done with forward-rotating agricultural machinery, such as the common rotary tiller.

Look at the use requirements, generally rotate the ground forward, and reverse the construction site or straw returning to the field.

How does the rotary tiller want to spin flat and fast First of all, confirm that the left and right coupling pins of the tractor moving plate are separated. Secondly, the rotary tiller should be lifted, unilateral brakes should be used, and the steering wheel should be killed at the same time to achieve a U-turn on the spot.

It is a tillage machine that is matched with a tractor to complete tillage and harrow operations. It has been widely used because of its strong soil crushing ability and flat surface after ploughing. Proper use and adjustment of the rotary tiller is important to maintain its good technical condition and ensure the quality of farming.

1. At the beginning of the operation, the rotary tiller should be in a lifting state.

First, in combination with the PTO shaft, the speed of the cutter shaft is increased to the rated speed, and then the rotary tiller is lowered to gradually sink the blade into the soil to the required depth. It is strictly forbidden to combine the blade with the power take-off shaft or descend sharply after the blade is put into the soil, so as not to cause the blade to bend or break and increase the load of the tractor.

2. In the operation, it should be slowed down as much as possible.

In this way, the quality of the work can be guaranteed, the clods can be finely crushed, and the wear and tear of the parts can be reduced. Pay attention to listen to the rotary tiller for noise or metal knocking sound, and observe the broken soil and ploughing depth. If there is any abnormality, it should be stopped immediately for inspection, and the operation can be resumed only after being eliminated.

3. When turning on the ground, it is forbidden to operate.

The rotary tiller should be raised so that the blades are off the ground, and the tractor throttle should be reduced to avoid damaging the blades. When lifting the rotary tiller, the inclination angle of the universal joint operation should be less than 30 degrees, and when it is too large, it will produce impact noise, which will cause it to wear or damage prematurely.

4. When reversing, crossing the ridge and transferring the plot, the rotary tiller should be lifted to the highest position and cut off the power to avoid damage to the parts.

If it is transferred to a distance, the rotary tiller should be fixed with a locking device.

5. After each shift, the rotary tiller should be maintained.

Remove the mud and weeds from the blades, check the fastening of each connector, fill the lubricating oil points with lubricating oil, and add butter to the universal joint to prevent aggravated wear.

Adjustment of the rotary tiller:

1) Left and right horizontal adjustment. The towing with rotary tiller is initially parked on the flat ground, the rotary tiller is lowered, the blade is 5 cm away from the ground, and the left and right knife tips are observed to be consistent with the height of the ground to ensure that the knife shaft is consistent in the operation and the ploughing depth is uniform.

2) Adjust the front and rear levels. When lowering the rotary tiller to the required depth, observe whether the angle between the universal joint and the axis of the rotary tiller is close to the horizontal position. If the angle of the universal joint is too large, the upper tie rod can be adjusted to make the rotary tiller in a horizontal position.

3) Lifting height adjustment. In rotary tillage operation, the angle of universal joints is not allowed to be greater than 10 degrees, and it is not allowed to be greater than 30 degrees when the head of the ground is turned. Therefore, for the lifting of the rotary tiller, for the use of the available screw of the position adjustment, the appropriate position of the handle is tightened and the limit is screwed; If you need to raise the rotary tiller again, the power of the universal joint should be removed.

Summary. No. The reverse rotary tiller cannot be changed to forward rotation, it is a single function, and the rotation direction of the rotary tiller cannot be converted forward and reversed. According to the rotation direction of the rotary tiller rotary tiller shaft, it can be divided into two categories: forward rotary tiller and reverse rotary tiller.

No. The reverse rotary tiller can not be changed to forward rotation, which is a single lack of power and fierce energy, and the rotation of the rotary imitation bridge tiller cannot realize the forward and reverse conversion. According to the rotation direction of the rotary tiller rotary tiller shaft, it can be divided into two categories: forward rotary tiller and reverse rotary tiller.

Do you have any questions?

Isn't there an age wheel box on the side of the reverse rotary tiller?

The side of the pro-reverse rotary tiller is not an age wheel box.

The working load of the rotary tiller is much heavier than that of the forward rotation, because the reversed knife shaft will give the tractor a reverse or nuclear force. One force forward, one force backward, quite a tug-of-war with the tractor, at least more than the forward rotation consumes about 30% more power, that is to say, the fuel consumption will be increased by the old shirt. The biggest advantage and benefit of the flip rotary tiller is that the farmland is better for stubble removal and stirring, because the operation speed of the tractor is slow, so the soil and straw can be fully hit, and the crushing effect is better.

The dragging with rotary tiller is initially parked on the flat ground, so that the knife oak is 5 cm away from the ground, and the height of the left and right knife tips from the ground is observed to ensure that the knife shaft is horizontal and the depth is uniform. When the front and rear horizontal adjustment lowers the rotary tiller to the depth of the tillage that needs to be returned to the beam, observe whether the angle of the universal joint is close to the horizontal position with the axis of the rotary tiller, if the angle of the universal joint is too large, the upper tie rod can be adjusted, so that the rotary tiller is in a horizontal position, and the angle of the universal joint is not allowed to be greater than 10 degrees in the rotary tillage operation, and it is not allowed to be greater than 30 degrees when the head of the ground is turned. Special attention should be paid when using the height adjustment lift, as well as changing the Zhengxuan Min cultivator to the opposite direction.

If it is necessary to raise the rotary tiller again, the power of the universal joint should be removed.

Hello, stop the towing with the slow rotary tiller on the flat ground, make the blade 5 cm away from the ground, and observe whether the left and right knife tips are consistent from the ground to ensure that the knife shaft is horizontal and the depth is uniform. When the front and rear horizontal adjustment lowers the rotary tiller to the required depth, observe whether the angle of the universal joint is close to the horizontal position with the axis of the rotary tiller, if the angle of the universal joint is too large, the upper pull rod can be adjusted to make the rotary tiller in a horizontal position, and the angle of the universal joint is not allowed to be greater than 10 degrees during the rotary tillage operation, and it is not allowed to be greater than 30 degrees when the head of the ground is turned. Special care should be taken when using height-adjustable lifting, as is changing the Zhengxuan cultivator to the opposite direction.

If it is necessary to raise the rotary tiller again, the power of the universal joint should be removed.

Compared with its complete land tillage machinery, the reverse rotary tiller has some disadvantages, mainly including:

1.Poor soil structure: The use of a reverse rotary tiller to turn the soil layer overturned, destroying the soil structure, reducing soil compactness and poor aeration.

2.Depth of tillage is not easy to control: When using a reverse rotary tiller, it is difficult to grasp the depth of ploughing, so there are situations where it is too deep or not deep enough, which may damage the root system of underground plants.

3.Low tillage efficiency: The use of a reverse rotary tiller for tillage requires the destruction of the same land multiple times, which increases energy consumption and has an impact on the ecological security of hail soils.

4.Great impact on the ecological environment: the reverse rotary tiller has strong ability, but when operating, it is easy to have a great impact on soil erosion, soil microorganisms and the natural ecological environment.

To sum up, although the reverse rotary tiller has the efficient ability of land cultivation, it also has obvious shortcomings, which need to be deeply understood and controlled.
