a small harvester

Abstract

The present invention aims to provide a small harvester, which includes a harvester main body, a load-bearing bracket, a gearbox, a walking mechanism and a claw assembly; the main body of the harvester is hinged to the load-bearing bracket, and the load-bearing bracket is connected to the gearbox. The gearbox is connected with the traveling mechanism; the main body of the harvester includes an upper scissors assembly and a driving device. The uniquely designed scissors assembly structure and the holding claw assembly structure of the present invention do not need to be provided with a mechanical device for discharging rice stalks, which avoids the subsequent mechanical failure and can well solve the problem of pushing the cut rice stalks against the front rice stalks. The ear of rice leans forward, which affects harvesting and causes technical problems of rice loss.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a small harvester. Background technique [0002] At present, rice and wheat are widely used in rural areas to promote mechanical harvesting. Due to the fact that the farmland cannot be cultivated uniformly, resulting in differences in harvesting periods, there are small farmlands in the south, and the depth of field mud is different, which restricts the adaptability of large harvesters. The small harvester breaks through the bottleneck that large harvesters cannot harvest in rural areas, promotes the mechanization of harvesting operations, shortens the labor cycle, and liberates people from heavy physical labor. Widely used to harvest wheat, rice, barley, hemp, beans and other crops. Replace the corresponding knives, install the upper and lower pallets and a safe protective cover, and you can also harvest shrubs, pastures, reeds, tea garden branch pruning and flower beds. ...

AI Technical Summary

Problems solved by technology

[0003] In the existing double-scissors small harvester, because of the difference in the working angles of the upper and lower scissors, the left and right support rods of the Fuhe sprocket bracket are installed in the middle behind the Fuhe support to hinder the movement of the cut rice stalks, and the rice stalks are piled up on the scissors. The uncut rice stalks in front of the press are tilted forward

Also push the uncut ears of rice with the upper scissors forward, affecting the normal work of the upper and lower scissors

Especially when harvesting the first and last rows of rice ears, the rice ears lean forward more obviously, and cannot be completely cut, which will easily cause the problem of increased harvesting loss rate.

[0004] Most of the existing small harvesters are wheel-driven, which has the disadvantages that the wheel-type driving wheels are easy to slip, the drive in deep mud fields collapses, the grounding area of ​​the driving wheels is small, and it is easy to overturn, poor in stability and difficult to operate.

The existing small harvester crawler drives have different gearbox designs, high production costs, poor parts standards, and difficult maintenance

The design of the track system is clumsy, the amount of material used is large, and the weight is heavy, which cannot meet the requirements of lightness and easy operation for farmland operations and short-distance agricultural transportation, which limits the application of the track drive system on small harvesters
