Stalk pulling roller capable of preventing grass intertwining

Abstract

The invention relates to a stalk pulling roller capable of preventing grass intertwining and belongs to the technical field of agricultural machinery. The stalk pulling roller comprises a stalk pulling shaft and a plurality rows of V-shaped toothed plates and is characterized in that the stalk pulling shaft is rotatably arranged on a rack, the V-shaped toothed plates are circumferentially arrangedon the stalk pulling shaft at intervals, a rotary disk is fixed at each of the two ends of the stalk pulling shaft, a shell fixed on the rack covers the outer side of each rotary disk, and a triggering rack group located between each shell and the corresponding rotary disk is fixed on the inner side of the shell; U-shaped clamp seats are arranged at two ends of each row of V-shaped toothed platesin a clamped manner, push plates fixed on the corresponding U-shaped clamp seats are arranged on two sides of each row of V-shaped toothed plates, drive racks are fixed on the U-shaped clamp seats, rotary shafts penetrates the rotary disks, one ends of the rotary shafts are provided with drive gears constantly meshing with the drive racks, the other ends of the rotary shafts are provided with triggering gears, and the triggering gears mesh with the racks in the triggering rack groups when the rotary shaft rotates to a set position. The stalk pulling roller has the advantages that intertwininggrass can be cleaned from inside to outside, tooth cleaning can be achieved, and grass intertwining of the toothed plates can be prevented.

Description

technical field [0001] The invention relates to a stalk pulling roller, which belongs to the technical field of agricultural machinery. Background technique [0002] Cotton straw is a by-product of cotton production and an important resource for the development of industries such as industry, sideline and agriculture. The performance of the existing cotton stalk harvesting equipment depends on the performance of the cotton stalk pulling mechanism. [0003] According to the applicant's understanding, the double-toothed disc type cotton stalk pulling machine is now commonly used. This kind of cotton stalk pulling device has high requirements on the operator and needs to be harvested in the correct row, so it is difficult to further improve the cotton stalk pulling efficiency. There are also areas where the four-edged knife-type cotton stalk pulling method is adopted, which requires four-edged knife to work in the soil, and the energy consumption is relatively large.
