Grate comb type of fruit-picking device for peanut harvester

Abstract

The invention discloses a grate comb type of fruit-picking device for a peanut harvest, and belongs to the technical field of peanut harvesters. The grate comb type of fruit-picking device comprises more than two fruit-picking mechanisms, the fruit-picking mechanism comprises a frame, a fruit-picking roller and a fruit-picking trough, the fruit-picking roller comprises a fruit-picking roller rotary drum, the cylinder surface of the fruit-picking roller rotary drum is evenly distributed with movable teeth of the fruit-picking roller, the fruit-picking roller rotary drum is supported on the leftand right sides of the frame by the left end and the right end of the rotating shaft of the fruit-picking roller rotary drum respectively, the fruit-picking roller is provided with a fruit-picking transmission connection part of the fruit-picking roller, the fruit-picking trough comprises a fruit-picking trough body and fixed teeth, the fruit-picking trough body is located at the bottom of the fruit-picking roller, the left wall of the fruit-picking trough body and the right wall of the fruit-picking trough body are respectively fixed on the left side and the right side of the frame, the bottom wall of the fruit-picking trough body is provided with at least one row of fixed teeth, and the fixed teeth are arranged at intervals from the left wall of the fruit-picking trough body to the right wall of the fruit picking trough body along the axis direction of the rotating shaft of the fruit-picking roller rotary drum. The device has the characteristics of thorough fruit picking, low rate of broken shell, high working efficiency, etc.

Description

technical field [0001] The invention relates to the technical field of peanut harvesters. Background technique [0002] Peanuts are widely planted in our country, and peanut harvesters play an important role in the peanut harvesting process. Peanut harvesters currently used generally use the beating method to pick peanuts, and the peanut seedlings are driven by the rotating device to rotate at a high speed. The effect of gravity is separated from the peanut seedlings. This method of picking fruit has certain strength requirements for the beating of peanut seedlings on the mesh support, and requires some small brute force. Therefore, there are certain requirements for the rotation speed and power of the rotating device. Peanut seedlings During the beating process, some peanuts are inevitably directly beaten on the mesh support, which easily causes the shell to break, and the peanut kernels are prone to mold and deterioration in the later stage due to the loss of the shell pr...

Peanut harvesters currently used generally use the beating method to pick peanuts, and the peanut seedlings are driven by the rotating device to rotate at a high speed. The effect of gravity is separated from the peanut seedlings. This method of picking fruit has certain strength requirements for the beating of peanut seedlings on the mesh support, and requires some small brute force. Therefore, there are certain requirements for the rotation speed and power of the rotating device. Peanut seedlings During the beating process, some peanuts are inevitably directly beaten on the mesh support, which easily causes the shell to break, and the peanut kernels are prone to mold and deterioration in the later stage due to the loss of the shell protection, thereby affecting the quality of the peanut harvest. Due to the different dry humidity of peanut seedlings, the force required for fruit picking is different, and the requirements for the rotating speed of the rotating device are also different. If the rotating speed is too high, it is easy to cause the shell to break, and if the rotating force is too small, it will affect the fruit picking rate. Therefore, adopt The peanut harvester with the beating separation method has the disadvantages of high shell breaking rate, high fruit picking rate affected by the dry humidity of peanut seedlings, and unstable fruit picking performance.
