Winding preventing fruit picking roller mechanism

Abstract

The invention relates to a winding preventing fruit picking roller mechanism, belonging to the technical field of agricultural machineries. The mechanism comprises a pair of roller bodies capable of rotating relatively, two end plates of the roller bodies respectively extend out and are supported on a revolving shaft on a stand through a bearing, and the stand is fixed with a tubular protective cover extending from a bearing outer ring to the end plates of the roller bodies. The improvement of the invention is that the end faces of the end plates, adjacent to the protective cover, are provided with circular sinkings, and one end of the protective cover, adjacent to the end plates, stretches into the circular sinkings. Thus, the gap between the protective cover and the end plates of the roller bodies sinks in the sinkings of the end plates, and because plastic covering film cannot enter the sinkings of the end plates, the winding of the plastic covering film is effectively avoided.

Description

technical field [0001] The invention relates to a fruit picking roller on a peanut harvester, in particular to an anti-winding fruit picking roller mechanism, which belongs to the technical field of agricultural machinery. Background technique [0002] The fruit picking roller of existing peanut combine harvester is as figure 1 , 2 As shown in . The frame is fixed with a tubular shield 5 extending from the outer ring of the bearing to the end plate of the roller body. That is, a high-speed rotating shaft is installed in the stationary shield, and the transmission mechanism drives the shaft and the roller body. [0003] When working, the two rollers rotate relatively under the drive of the transmission mechanism, so that the peanuts on the peanut stalks fed between the two rollers are brushed off and picked off by the beating action of the radial fruit picking blades 9 on the rollers. . During this process, due to the shielding effect of the shield, branches and dirt can...

AI Technical Summary

Problems solved by technology

When picking fruit, the plastic film is easy to wrap around the two ends of the fruit picking roller, especially in the gap between the shield and the end plate of the roller body, resulting in frequent shutdowns for cleaning, which seriously affects the production of combined peanut harvesting Efficient and often difficult and time consuming to clean

[0004] In addition, the fruit-picking blades of the existing fruit-picking roller mechanism are all radially extending straight plates. When picking fruit, the pods have a high rate of stalks, and there are many broken seedlings and branches. The high rate of fruit pods with stalks requires more manpower to manually remove the fruit The fruit stalks on the pods, broken seedlings and broken branches increase the separation of peanut fruits and seedlings in the later stage of harvest, so the harvest quality needs to be improved
