Track walking type minitype rice combine harvester

Abstract

A caterpillar-chain walking-type micro rice combined harvester comprises a chassis, a walking device, a transmission mechanism, a conveying device, a reaping apparatus and a threshing mechanism, wherein, a dual-fan soot blower is arranged inside the threshing mechanism, the walking device is provided with a four-bar linkage control mechanism consisting of four transmission bars and a linkage so as to realize the consistent method for controlling the harvester both with the front operation bar and the rear operation bar and to realize the same operation controlling function; the walking caterpillar chain is an iron pouring composite that is composed of an upper dental plate and a lower dental plate which are arranged on a bridge chain in clamping way through bolts, wherein, the upper dental plate is provided with steel teeth, the lower dental plate is provided with rubber teeth with a lower-tooth steel bracket, and the bridge chain is a stratiform composite chain that is formed by a rubber layer and a nylon-wire layer. The present invention has the advantages of compact structure, small volume, light weight, flexible operation, low energy consumption and convenient maintenance, which is applicable to the small fields in the mountainous area and the hilly area.

Description

technical field [0001] The invention relates to a self-propelled combine harvester, in particular to a crawler walking type mini rice combine harvester. Background technique [0002] Most of the cultivated land in rural mountainous and hilly areas has many terraced fields, and the field area is small, so large-scale combine harvesters cannot be used. Harvesting food crops such as rice and wheat with traditional harvesting tools is labor-intensive and low-efficiency. The use of large combine harvesters is not suitable due to the complex terrain and small field area, and the economic cost is high, the power consumption is large, and maintenance is difficult. For the existing miniature combine harvester, when walking on uneven roads in mountainous and hilly areas, the harvester vibrates greatly and is very unstable. The manipulator sitting on the harvester is in danger of being shaken off the machine, which is very unsafe. Running on the ground, it is also vibrating, unstable ...

[0002] Most of the cultivated land in rural mountainous and hilly areas has many terraced fields, and the field area is small, so large-scale combine harvesters cannot be used. Harvesting food crops such as rice and wheat with traditional harvesting tools is labor-intensive and low-efficiency

The use of large combine harvesters is not suitable due to the complex terrain and small field area, and the economic cost is high, the power consumption is large, and maintenance is difficult

For the existing miniature combine harvester, when walking on uneven roads in mountainous and hilly areas, the harvester vibrates greatly and is very unstable. The manipulator sitting on the harvester is in danger of being shaken off the machine, which is very unsafe. It is also vibrating, unstable, and the iron track is worn out, easy to damage, and difficult to repair, which greatly affects the efficiency of the harvester.
