Description

A fruit picking mechanism for a peanut harvester

technical field

The utility model relates to the technical field of peanut harvesters.

Background technique

Peanut is a widely planted economic crop in my country, and peanut harvester plays a very important role in the peanut harvesting process. The peanut harvester currently used generally adopts the method of beating the fruit to pick off the peanut fruit, and drives the peanut seedling to rotate at a high speed through the rotating device. The action of gravity is separated from the peanut seedlings. This fruit picking method has a certain strength requirement for the peanut seedlings to be beaten on the mesh support, and requires a little brute force. Therefore, there are certain requirements for the rotation speed and power of the rotating device. During the beating process, some peanuts will inevitably be directly hit on the mesh support, which will easily cause the husk to be broken. Because the peanut kernels lose the protection of the husk, they are prone to mildew and deterioration in the later stage, thus affecting the quality of peanut harvesting. Due to the different dryness and humidity of peanut seedlings, the strength required for fruit picking is different, and the requirements for the rotation speed of the rotating device are also different. The peanut harvester with the beating separation method has the disadvantages of high husk breakage rate, the fruit picking rate is greatly affected by the dry humidity of peanut seedlings, and the fruit picking performance is unstable.

Utility model content

The technical problem to be solved by the utility model is to provide a fruit picking mechanism for a peanut harvester, which has the characteristics of clean fruit picking, low husk breakage rate and high working efficiency. It is applicable to both dry and wet stems of peanut seedlings.

In order to solve the above-mentioned technical problems, the technical scheme adopted by the present utility model is:

A fruit picking mechanism for a peanut harvester, comprising a frame, a fruit picking roller and a fruit picking trough, the fruit picking roller comprises a fruit picking roller drum, the fruit picking roller moving teeth are evenly distributed on the cylindrical surface of the fruit picking roller drum, and the fruit picking roller drum passes through the rotation shaft of the fruit picking roller drum. The left end and the right end are respectively supported on the left and right sides of the frame. The fruit picking roller is provided with a fruit picking roller drive connection part. The fruit picking trough includes a fruit picking trough body and a fixed tooth. The fruit picking trough body is located at the bottom of the fruit picking roller. The left side wall of the fruit picking trough body and the right side wall of the fruit picking trough body are respectively fixed on the left and right sides of the rack, and at least one row of fixed teeth is arranged on the bottom wall of the fruit picking trough body. The left side wall to the right side wall of the fruit picking trough body is arranged at intervals along the axis direction of the rotating shaft of the fruit picking roller, and the gaps between the fruit picking roller moving teeth and the fixed teeth of the fruit picking roller correspond to the gaps; the engine power output shaft of the peanut harvester passes through The transmission device drives the transmission connection part of the fruit picking roller to rotate. The fruit picking roller moving teeth located in the fruit picking trough body pull the peanut seedlings from the front of the fruit picking trough body to the rear, and the fruit picking roller moving teeth pass through the gap between the fixed teeth, so as to remove the peanuts. The seedlings have a splitting effect in the opposite direction, so as to pull the peanuts away from the peanut seedlings.

The utility model is further improved by:

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

Each fixed tooth in the fruit picking mechanism is inclined to the rear, and is equipped with an inclination angle adjustment structure: each row of fixed teeth is fixed on each fixed tooth angle adjustment shaft at intervals, and the fixed tooth angle adjustment shaft is located below the bottom wall of the fruit picking slot body, The left and right ends of the angle adjustment shaft of the fixed teeth are respectively connected to the left and right sides of the frame in rotation, and strip holes for screening out the soil are arranged at horizontal intervals on the bottom wall of the fruit picking trough. The strip hole on the bottom wall of the fruit picking trough body extends into the groove cavity of the fruit picking trough body, the angle adjustment handle is radially fixed at the end of the fixed tooth angle adjustment shaft, and the angle adjustment handle is provided with a positioning hole , There are a plurality of angle adjustment holes corresponding to the positioning holes on the angle adjustment handle on the frame. When the bolts are inserted into the different angle adjustment holes through the positioning holes on the angle adjustment handle, the fixed teeth correspond to different angle of inclination.

Both the moving teeth and the fixed teeth of the fruit picking roller are elastic teeth. The elastic teeth are formed by extending the end part of the coil spring to the vertical direction of its axial direction.

Make the fruit picking roller move from front to back in the fruit picking trough, and pull the peanut seedlings located in the fruit picking trough from the front to the back. Since the peanut seedlings are in the shape of flexible and soft branches, they will be entangled in the process of conveying to the rear. On the fruit-picking roller teeth, when the fruit-picking roller teeth pass through the gap between the fixed teeth, the fixed teeth on both sides of the fruit-picking roller teeth will squeeze and tear the peanut seedlings in the opposite direction. The fruit is larger and is attached to the more flexible peanut seedling. During the extrusion process, the peanut fruit will be extruded from the inside of the peanut seedling. The peanuts squeezed out from the inside of the seedlings are attached (supported) to the peanut seedlings, and when they come into contact with the fixed teeth of the fruit picking roller, a force is generated, so that the fixed teeth of the fruit picking rollers have a reaction force on the peanut fruit, and the peanut fruit is removed from the peanut seedling. Take it off.

Since the fruit picking mechanism is vigorously kneading and has a direct effect during the fruit picking process, the stems of the peanut seedlings will not be affected whether they are wet or dry during the fruit picking process. The rate of husk breakage is reduced. It has the characteristics of clean fruit picking, low husk broken rate and high working efficiency.
