Description

Cotton picker with cotton picking head assembly convenient to maintain Technical Field The invention relates to the technical field of cotton picker manufacturing, in particular to a cotton picker with a cotton picker head assembly convenient to maintain. Background The cotton planting range in China is quite wide, the picking of the cotton in the past mainly depends on hands, the labor intensity is high, and the efficiency is low. With the continuous improvement of the agricultural mechanical level in China, the development of large-scale cotton picking is a trend of cotton industry in China, so that cotton pickers appear on the market. By using the cotton picker, the cotton picking speed can be effectively improved, and higher income is created for cotton picker. However, the picking effect, the net picking rate and the cotton removing effect of the existing mechanized cotton picker head in China are not ideal, the main reason is that the cotton picker head is unreasonably designed, the core components affecting the picking effect, the net picking rate and the cotton removing effect in the cotton picker head are the picking heads used as picking devices, generally, a plurality of picking heads are driven by one oil cylinder, and the reduction boxes of the adjacent picking heads are in transmission connection. The transmission between the head reduction boxes of the cotton picker is realized by connecting the transverse shafts of the adjacent reduction boxes through the linkage shaft, but due to the limitation of the spacing of the heads, the transmission rod needs multiple specifications, and the debugging during installation is also troublesome. The cotton picking head reduction gearbox is arranged on the cotton picking head for use, the distance between the cotton picking heads is designed according to cotton planting density, after the cotton picking head is arranged, a large access door at the side part of the cotton picking head cannot be opened, when the cotton picking head is in trouble-shooting, the cotton picking head can not be moved due to the fact that a connecting rod is required to be detached due to limited space, the distance is enabled to meet the requirement of a large distance for opening a door, the detachment and the installation of each time are very troublesome, meanwhile, the existing cotton picking head is designed to be 90 centimeters according to the distance between cotton ridges in the United states, and the distance between cotton ridges in a standard mode in a part of China is only 76 centimeters, as shown in fig. 1, two arms of a ridge divider of an existing cotton picking head assembly are diverged to two sides, but the cotton picking head with the large distance cannot be picked at a row spacing lower than 76 centimeters, and the applicability is poor in China. Disclosure of Invention Aiming at the problems, the invention aims to provide the cotton picker with strong applicability and convenient installation and maintenance of the cotton picking head assembly. In order to solve the technical problems, the cotton picker with the cotton picking head assembly convenient to maintain has the following technical scheme that the cotton picking machine is provided with a frame, the cotton picking head assembly is arranged on the frame and comprises cotton picking heads and a fixing frame, the cotton picking heads are arranged on the frame through the fixing frame, and a cotton stripping disc assembly and a reduction gearbox are arranged in a shell of the cotton picking head. The speed reduction box is provided with a box body, a spline cross shaft and a spline vertical shaft are arranged in the box body, the spline cross shaft is connected with the spline vertical shaft through bevel gear transmission, the spline vertical shaft is connected with the cotton stripping disc assembly in transmission, and the spline cross shafts of the speed reduction box of two adjacent cotton picking heads are connected through transmission rods in transmission. The transmission rod is provided with a connecting pipe and a connecting rod, the outer end of the connecting pipe is fixedly connected with a first cross-shaped connecting seat, the outer end of the connecting rod is fixedly connected with a second cross-shaped connecting seat, the inner end of the connecting rod is inserted into the connecting pipe, an anti-rotation structure is arranged between the connecting pipe and the first cross-shaped connecting seat, and an anti-rotation structure is also arranged between the connecting pipe and the connecting rod. The cotton picking head is provided with a ridger, the ridger comprises a first ridging arm and a second ridging arm, and the first ridging arm is vertically arranged on the cotton picking head. The cotton picking head is arranged on the fixing frame through a fixing bolt, a guide skirt is arranged on a bolt sleeve of the fixing bolt, and the guide skirt is arranged on the guide rod. In
