Description

Technical Field

[0001] The invention relates to the technical field of peanut harvesters. Background Art

[0002] Peanuts are a widely planted economic crop in my country, and peanut harvesters play a very important role in the peanut harvesting process. The peanut harvesters currently used generally adopt a beating-type fruit picking method to pick the peanut fruits. The peanut vines are driven to rotate at high speed through a rotating device. During the rotation, the peanut vines are beaten on the mesh support, so that the peanut fruits are separated from the peanut vines due to gravity. This fruit picking method has certain force requirements for the peanut vines to be beaten on the mesh support, which requires some brute force, and therefore has certain requirements for the rotation speed and power of the rotating device. During the beating process of the peanut vines, some peanut fruits inevitably fall directly on the mesh support, which can easily cause the shells to break. The peanut kernels lose the protection of the shells and are prone to mold and deterioration in the later stage, thereby affecting the quality of the peanut harvest. At the same time, due to the different dryness and humidity of the peanut vines, different forces are required when picking the fruits, and different requirements are placed on the rotation speed of the rotating device. If the rotation speed is too large, the shells are easily broken, and if the rotation force is too small, the picking rate will be affected. Therefore, the peanut harvester using the beating-type separation method has the disadvantages of high shell breakage rate, great influence of peanut vine dryness and humidity on the picking rate, and unstable picking performance. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fruit picking mechanism for a peanut harvester, which has the characteristics of clean fruit picking, low shell breakage rate, high working efficiency, etc. It is applicable to both dry and wet stems of peanut vines.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A fruit picking mechanism for a peanut harvester comprises a frame, a fruit picking roller and a fruit picking groove, wherein the fruit picking roller comprises a fruit picking roller drum, and fruit picking roller movable teeth are evenly distributed on the cylindrical surface of the fruit picking roller drum, and the fruit picking roller drum is supported on the left and right sides of the frame respectively through the left and right ends of the fruit picking roller drum rotating shaft, and the fruit picking roller is provided with a fruit picking roller transmission connection component, and the fruit picking groove comprises a fruit picking groove body and fixed teeth, and the fruit picking groove body is located at the bottom of the fruit picking roller, and the left side wall of the fruit picking groove body and the right side wall of the fruit picking groove body are respectively fixed on the left and right sides of the frame, and at least one row of The fixed teeth are arranged at intervals from the left side wall of the fruit picking trough body to the right side wall of the fruit picking trough body along the axial direction of the rotating shaft of the fruit picking roller, and the gaps between the moving teeth of the fruit picking roller and the fixed teeth correspond to each other; the engine power output shaft of the peanut harvester drives the transmission connecting component of the fruit picking roller to rotate through the transmission device, and the moving teeth of the fruit picking roller located in the fruit picking trough body pull the peanut vines from the front of the fruit picking trough body to the rear, and the moving teeth of the fruit picking roller pass through the gaps between the fixed teeth, thereby producing a pulling effect on the peanut vines in the opposite direction, so as to pull the peanuts off the peanut vines.

[0006] The present invention is further improved in that:

[0007] The distribution of the moving teeth of the fruit picking roller on the outer surface of the fruit picking roller drum is as follows: the moving teeth of the fruit picking roller are arranged at equal intervals along the circumference of the fruit picking roller drum to form circumferential fruit picking roller moving tooth groups, and the moving teeth of the fruit picking roller are arranged at equal intervals along the radial direction of the fruit picking roller drum to form radial fruit picking roller moving tooth groups, and each circumferential fruit picking roller moving tooth group is formed by the moving teeth of the fruit picking roller in the spaced radial fruit picking roller moving tooth groups being arranged at equal intervals in the radial direction, and the radial arrangement positions of the moving teeth of the fruit picking roller in the adjacent radial fruit picking roller moving tooth groups correspond to the gaps of the fixed teeth, and the radial arrangement spacing of the moving teeth of the fruit picking roller in the adjacent radial fruit picking roller moving tooth groups is the dynamic spacing of the moving teeth of the fruit picking roller.

[0008] The fixed teeth in the fruit picking mechanism are inclined backward and are provided with an inclination angle adjustment structure: each row of fixed teeth is fixed at intervals on each fixed tooth angle adjustment shaft, the fixed tooth angle adjustment shaft is located below the bottom wall of the fruit picking groove body, the left and right ends of the fixed tooth angle adjustment shaft are rotatably connected to the left and right sides of the frame respectively, and strip holes for screening out debris are arranged at intervals on the bottom wall of the fruit picking groove body horizontally, and each fixed tooth passes through the strip holes on the bottom wall of the fruit picking groove body from the bottom and extends into the groove cavity of the fruit picking groove body, and an angle adjustment handle is radially fixed at the end of the fixed tooth angle adjustment shaft, a positioning hole is provided on the angle adjustment handle, and a plurality of angle adjustment holes corresponding to the positioning holes on the angle adjustment handle are provided on the frame, and when a pin is inserted into each different angle adjustment hole through the positioning hole on the angle adjustment handle, each fixed tooth corresponds to a different inclination angle.

[0009] The moving teeth and fixed teeth of the fruit picking roller are both elastic teeth. The elastic teeth are formed by the end part of the coil spring extending in the vertical direction of its axial direction. The axis of the coil spring is parallel to the axis of the fruit picking roller, so that the elastic teeth are elastic in the forward and backward directions of the circumference of the roller to which they are fixed, and the moving teeth of the fruit picking roller are inclined in the opposite direction of the rotation of the roller.

[0010] The bottom wall of the fruit picking groove body of the fruit picking mechanism is an arc-shaped bottom wall, and the arc-shaped bottom wall is coaxial with the fruit picking roller.

[0011] The fruit picking roller is a hollow structure roller.

[0012] The beneficial effects of adopting the above technical solution are:

[0013] The present invention is designed based on the characteristics that peanut vines are in the shape of soft branches with toughness, while peanut fruits are in the shape of large grains. The peanut fruits are picked by a comb-type fruit picking method. The fruit picking roller is driven by a transmission device to operate so that the movable teeth of the fruit picking roller operate from front to back in the fruit picking groove, and the peanut vines located in the fruit picking groove are pulled from the front to the rear. Since the peanut vines are in the shape of soft branches with toughness, they will be entangled on the movable teeth of the fruit picking roller during the backward transportation. When the movable teeth of the fruit picking roller pass through the gaps between the fixed teeth, the movable teeth of the fruit picking roller are located at the movable teeth of the fruit picking roller. The fixed teeth on both sides will squeeze the peanut vines and pull them in opposite directions. Since the peanuts are large and attached to the relatively flexible peanut vines, the peanuts will be squeezed out from the inside of the peanut vines during the squeezing process. During the pulling process, the peanuts outside the peanut vines and the peanuts squeezed out from the inside of the peanut vines are attached (supported) to the peanut vines, and generate force when they come into contact with the front of the fixed teeth of the fruit picking roller, so that the fixed teeth of the fruit picking roller generate a reaction force on the peanuts to pick them off the peanut vines.

[0014] Since the picking mechanism applies force and directly acts during the picking process, the stems of the peanut vines are not affected regardless of whether they are dry or wet. Since the picking method is different from the beating method, the shell breakage rate is greatly reduced. It has the characteristics of clean picking, low shell breakage rate and high work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
