Cotton stalk puller

Abstract

The invention relates to a cotton stalk puller and belongs to the technical field of agricultural machinery. The cotton stalk puller consists of a frame, a transmission case, a transmission shaft, a transfer case, a cotton stalk pulling device, a cotton stalk delivery device and the like. The transmission case is arranged at the middle part of the frame and is provided with the transmission shaft; and one end of the transmission shaft is equipped with the transfer case, the cotton stalk pulling device is arranged on a mounting adjusting arm of the frame, and the upper part of the frame is provided with the cotton stalk delivery device which is connected with the transmission shaft by the transfer case. An eccentric shaft structure used in shift forks and a roller is adopted in the cotton stalk puller for connection fit, and a shift fork opening takes helical arrangement on the surface of the roller, thus causing the adjacent two shift forks to have a certain superposed size and ensuring that the stalk pulling device pulls the whole area within the working range; and line centering is unnecessary for stalk pulling, and the cotton stalk puller is not affected by cotton stalk lodging and weeds, thus improving the stalk pulling efficiency. The cotton stalk puller solves the problems that the existing cotton stalk pulling machinery removes the stalks without removing roots, is unfavorable for the subsequent crop growth, has difficult turning and difficult line centering in fields and has poor feeding. The cotton stalk puller is suitable for the cotton stalk pulling in various farmlands.

Description

Technical field: [0001] The invention relates to a cotton rod pulling machine, which belongs to the technical field of agricultural machinery. Background technique: [0002] In agricultural production, the stalks (stalks) of the crops must be removed after harvesting, especially cotton, because their rhizomes are not easy to rot, and being buried in the soil will affect the cultivation of the next year, and the existing cotton stalks are crushed and returned to the field for removal. Solve the above problems. At present, there are two methods of harvesting cotton stalks: manual and mechanical. The manual method is to pull out the cotton stalks one by one with both hands. The mechanical type uses a cotton stalk harvester to remove the cotton stalks. This cotton stalk harvester is generally divided into three types: cutting type, shovel type and clamping and pulling type. The cutting type uses a cutting machine to cut the cotton stalks above the ground. Its disadvantage is t...

[0002] In agricultural production, the stalks (stalks) of the crops must be removed after harvesting, especially cotton, because their rhizomes are not easy to rot, and being buried in the soil will affect the cultivation of the next year, and the existing cotton stalks are crushed and returned to the field for removal. solve the above problems

At present, there are two methods of harvesting cotton stalks: manual and mechanical. The manual method is to pull out the cotton stalks one by one with both hands.

The mechanical type uses a cotton stalk harvester to remove the cotton stalks. This cotton stalk harvester is generally divided into three types: cutting type, shovel type and clamping and pulling type. The cutting type uses a cutting machine to cut the cotton stalks above the ground. Its disadvantage is that it does not remove the roots; the shovel type uses shovel cutting parts to break the root of the cotton stalk, and the cotton stalk is lifted out of the ground along the plane of the shovel, because the shovel enters the soil at an angle of 45 degrees, and its disadvantage is that the root of the cotton stalk often It can only be shoveled in half, and the other half remains in the soil; the existing clamping and pulling cotton stalk harvesters all use branch pulling rods, which need to work in opposite directions; Poor input performance, greatly affected by cotton stalk lodging degree, weeds, etc., so the work efficiency is low, power consumption is high, and it is difficult to work on the edge of the field. Farmers have to supplement manual work when harvesting cotton stalks, and popularization and application are very difficult. big limit
