Cotton harvesting machinery is divided into two categories: cotton boll picking machine and cotton picker; Cotton pickers are divided into two types: cotton harvesting machine and cotton harvester; Now the market is usually used cotton harvester, according to the basic principle of cotton harvesting and the structure of its harvesting head is different, cotton harvester is divided into walking horizontal spindle picking cotton picker, walking vertical picking spindle cotton picker. Because the standard spindle picking cotton picker has a relatively high work efficiency, a high net recovery rate (about 96%), and a relatively low impurity rate (about 10%), it now occupies a dominant position in the market. Replacing manual cotton picking with equipment has become a key reform measure for the cotton picking industry and the further development of the entire cotton textile industry chain.
According to the difference in the way of acquisition, the cotton harvesting machinery is generally divided into two categories: cotton boll picking machine and cotton picker; Among them, the cotton picker is divided into two kinds, one is the cotton harvester that selectively harvests cotton according to the maturity of cotton, and the other is the cotton harvester that harvests all the leaves and peaches in connection with the cotton, and then clears the flowers and completes the operation at one time; The exemplary products in the cotton harvester are the scraper brush cotton harvester manufactured by John Deere Company abroad, and the cotton harvester made in Croatia by combing and stripping errors, because the net harvesting rate of the cotton harvester cannot be guaranteed, so the overall use of the area and demand is small.
Now the market is usually used cotton harvester, according to the basic principle of cotton harvesting and the structure of its harvesting head is different, cotton harvester is also divided into two kinds: one is the United States John Deere, Case enterprises as the representative of the manufacturing of walking level spindle picking cotton machine, most of the world's key cotton production capital city application of this cotton picker, the current Chinese market in the hot selling cotton picker most of the level spindle picking cotton picker;
The other is a walking vertical spindle picking cotton picker made by the Tashkent Cotton Machinery Bureau of Serbia, which is the key to some cotton picking areas in the former Soviet Union. The main disadvantages of the comparison between the vertical spindle picking cotton picker and the horizontal spindle picking cotton picker are: the work efficiency is relatively low, the impurity content is relatively high, the relevant experiments show that the net picking rate of the horizontal spindle picking cotton picker is 96%, and the impurity rate is about 10%, which is much higher than the vertical pick-up spindle cotton picker, Xinjiang cotton area has purchased this vertical pick-up cotton picker in the early days, but due to this defect, it has basically been no longer used.
-
The operation efficiency will be improved, and the net recovery rate will be relatively high. At this time, it can be judged according to the operation and appearance.
-
The purpose of the two should be different. It is necessary to distinguish by the final effect. The cotton harvested in the former may be of higher quality.
-
Some of the structures inside are different, and there is no way to judge the shape well, and it can be determined according to the way the cotton is harvested.
The Hong Kong aircraft (complicated version) is a parallel import in the mainland, the mainland aircraft (simplified Chinese version) is a parallel import in Hong Kong, and the European version is a parallel import in China. (Relative to the region) can be brushed into the text version you want.
Their nature is the same, they are all to separate the LCD screen of the mobile phone from the cover. It's just that the refrigeration separator disassembles and splits the stripping method at low temperature; The manual separator is fixed by the equipment, and the liquid crystal and the cover plate need to be separated manually and slowly, which requires some time of work in the middle.
The characteristics of strategic reconnaissance planes are that they fly at a high altitude and have a long range, and they are equipped with sophisticated aerial cameras and electronic reconnaissance equipment, and they can penetrate deep into the territory of the opposing side from a high altitude to carry out reconnaissance of strategic targets such as military and industrial centers, nuclear facilities, missile test and launch bases, and air defense systems. Typical strategic reconnaissance aircraft include the U-2 of the United States and reconnaissance aircraft flying at an altitude of 20,000 meters and a speed of 800 kilometers per hour. The SR-71 strategic reconnaissance aircraft is equipped with a high-resolution aerial camera and image radar, electronic reconnaissance equipment that can detect radio communications and radar wave characteristics, a side-looking radar that can peep into the other side of the border at a depth of several hundred kilometers, and can cross the enemy's airspace at an altitude of 24,000 meters at a speed three times the speed of sound when performing a mission, and carry out reconnaissance of an area of 150,000 square kilometers per hour. >>>More
The HL type ring chain centrifugal bucket elevator is composed of a moving part (hopper and traction chain), an upper section with a transmission sprocket, a lower section with a tensioning pulley, an intermediate casing, a driving device, a backstop brake device, etc. The hopper of the hoist is arranged intermittently, and the "digging method" is used for loading and the "centrifugal feeding method" is used for unloading. The traction mechanism of this hoist is two ring chains. >>>More
The difference between servo press and hydraulic press is mainly the power source: the power source of the traditional hydraulic press and the pneumatic press is the compressed air of the hydraulic oil, and the actuator is the hydraulic cylinder pneumatic cylinder. The main control objects of the equipment are the pressure of hydraulic oil compressed air, the speed of hydraulic oil compressed air entering and exiting the cylinder. >>>More
