What is the working principle of the scraper conveyor?

A bucket conveyor is a bucket conveyor whose hopper rotates on a pin between two chains, and can move horizontally to the discharge point and flip the hopper to discharge the material. Compared with ordinary bucket conveyors, the hopper of the rotary bucket conveyor can rotate on the pin shaft between the two chains, which makes the conveyor better maintain the stability of the material during transportation and reduce the scattering and loss of the material. At the same time, the flipping design of the hopper also makes the unloading more convenient and efficient.

Bucket conveyors are widely used in material transportation in mining, metallurgy, chemical industry, environmental protection, refractory and other industries. Xinxiang Hengyu Machinery Equipment Co., Ltd., the source manufacturer of screening and conveying equipment for 18 years, independently develops and produces: Z-type bucket elevator, square swing screen, U-shaped screw conveyor, tubular screw conveyor, fine screening...

The working principle of the scraper conveyor is to fix the open chute as a bearing part of coal, gangue or materials, etc., and fix the scraper on the chain (forming a scraper chain) as a traction member. When the head transmission part is started, the sprocket on the head shaft is driven to rotate, so that the scraper chain runs in circulation and drives the material to move along the chute until it is unloaded at the head of the machine. The scraper chain bypasses the sprocket for stepless closed cycle operation to complete the conveying of materials.

The motor drives the sprocket through the reducer and drives the scraper on the chain to scrape the material.

According to the surveying and mapping size or the material of the middle plate, bottom plate and side plate of the transition groove (robot or manual plasma blanking); Welding of the middle plate, bottom plate, side plate and wear strip (wear block) of the head frame; grinding the surface of the head frame; Paint treatment of the head frame (multiple times); The finished product of the head frame is put into storage and enters the state of waiting for delivery. The more important part of the production process of the headframe is the selection of materials for the middle plate, bottom plate and side plate, followed by the quality of the welding itself, which will affect the quality and service life of the final finished headframe. The relevant scraper conveyor accessories fixed on the head frame mainly include:

Motors, reducers, sprocket shaft sets, derailleurs, guard plates, left and right briquetting, connecting covers, connecting discs, left half couplings, right half couplings, brake plates, etc.

Summary. 1.Calculation of conveying capacity The conveying capacity of the scraper conveyor refers to the quality of the conveyor to transport the cargo load per hour. It depends on the quality of the load per meter length of the conveyor and the chain speed. i.e. q=

1.Calculation of conveying capacity The conveying capacity of the scraper conveying and dismantling machine refers to the quality of the conveyor to transport the cargo load per hour. Its ballast width depends on the mass and chain speed of the load per meter length of the conveyor. i.e. q=

2.The sum of the resistances running between the points.

The structure of the buried scraper conveyor is reasonable, it can be fed at multiple points, and the moving speed of the scraper is driven by the planetary cycloid pinwheel reducer, which runs smoothly and has low noise.

Principle: When the buried scraper conveyor is conveyed horizontally, the material is affected by the pressure of the scraper chain in the direction of movement and the weight of the material itself, which produces internal friction between the materials. This friction ensures the stable state between the material layers, and is enough to overcome the external friction caused by the movement of the material in the machine tank, so that the material forms a continuous overall material flow and is conveyed.

When the Gongyi Yili buried scraper conveyor is vertically lifted, the material is subjected to the pressure of the scraper chain in the direction of movement, which generates the lateral pressure in the horizontal direction in the material, forming the internal friction of the material. At the same time, due to the continuous feeding of the lower horizontal section, the lower material successively produces a pushing force on the upper material. This friction and pushing force are enough to overcome the external friction resistance caused by the movement of the material in the machine groove and the weight of the material itself, so that the material forms a continuous overall material flow and is lifted.

The scraper conveyor and the buried scraper are the same thing as the conveyor, but the scraper conveyor is fixed on the spot; The buried scraper conveyor is to make a trench under the horizontal ground and fix the scraper conveyor in the trench. Compared with the two, the buried scraper conveyor is conducive to environmental protection in the trench.

The explanation in the book is that the buried scraper conveyor is named because the material buries the scraper, and the main difference between it and the ordinary scraper conveyor is that its working environment is completely closed, only the inlet and the outlet, and the other environments are fully enclosed;

The second is that the efficiency of transporting materials is different, the ordinary one is not completely buried, and this kind of completely buried, if the amount of material is certain, then use it, the volume occupation will be smaller.

Buried scraper conveying is to continuously transport materials in the closed rectangular section of the shell with the help of a moving scraper chain. In the conveying too.

In the process, the scraper chain is buried in the material to be conveyed, so it is called"Buried scraper conveyor"。It uses the characteristics of internal friction and side pressure to scrape and transport materials. The material flow is continuous.

The buried scraper conveyor is a kind of closed continuous conveying equipment that can convey powder, small particles and small lumps of materials horizontally, inclination or vertically. The buried scraper conveyor uses the principle that the internal friction between the material particles is greater than the external friction between the material and the machine wall to make the material transported as a whole. Buried scraper conveyors utilize a lower scraper to drag the higher material layer.

When the ratio of the height of the material layer to the width of the machine groove meets certain conditions, the material flow is stable.
