Harvesting table of cotton harvester

Abstract

The invention belongs to parts for cotton harvesters in the field of agricultural machinery, and provides a harvesting table of a cotton harvester, which comprises a harvesting table frame, a divider, a depth limiting wheel, an upper row of comb teeth, a lower row of comb teeth, a baffle, a cotton stirring roll, an anti-stirring roll, a conveying screw, a cotton lifting roll, a hydraulic drive device, a transmission chain and a tension wheel. The harvesting table of the cotton harvester is characterized in that the harvesting table is disposed in the front so that field clearing and transferring are achieved; the harvesting table is provided with the composite comb teeth so that the problem that cotton plants are high and dense is solved; the cotton lifting roll is provided with telescopic lifting teeth and two additional feed inlets, the screw is provided with two left-hand rotation blades and two right-hand rotation blades, cotton in the middle moves to two sides, cotton at two ends moves to the middle, and accordingly the cotton is fed into the two feed inlets simultaneously, and the problem of blockage of the feed inlets is solved; a screw scraper is a linear arc plate, and a trapezoidal gap is reserved between the screw scraper and the axial direction of each screw blade, so that the problem of cotton back-throwing is solved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to parts for cotton harvesters. Background technique [0002] The harvesting table of the cotton harvester is used to harvest the cotton in the field and ensure that the cotton and bolls enter the feeding port smoothly. What adopt at present is the comb type side traction cotton harvester. The comb-tooth side traction cotton picking platform is installed on the movable support on the right side of the tractor. When the comb-toothed cotton machine is used for cotton harvesting, the cotton plants are introduced into the gap of the comb teeth, and the anti-plucking roller presses the cotton plants downward, and the cotton and bolls are separated from the cotton plants. The auger feeds the cotton and bolls into the feeding port in the middle, and then the cotton picking roller at the feeding port throws them back and upwards, and the airflow ejected from the airflow pipe install...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the existing technology are: when the comb-tooth side traction cotton harvester is used for cotton harvesting, the problems of field opening and field transfer must be solved. Manually picking cotton to open the road is time-consuming and laborious, and the productivity is reduced. The field transfer channel is reserved. It will inevitably cause waste of fields and reduce the income of cotton farmers; the feeding inlet is easy to block, and it needs to be stopped and cleaned manually, and the productivity is reduced; the phenomenon of back throwing at the auger bracket is serious, the cotton is thrown forward, and the cotton on the ground increases, reducing the income of cotton farmers; the spacing between the comb teeth is small , after harvesting, only the trunk of the cotton plant is left in the field, and the branches and stalks are sent to the picking table, which will inevitably cause a significant increase in the impurity content of machine-picked cotton; , Hanging cotton has greatly increased, reducing the income of cotton farmers
