Miniature soybean combine harvester

Abstract

The invention belongs to the field of agricultural machinery, and particularly discloses a miniature soybean combine harvester which comprises a machine frame, a power device assembly, a crawler walking device, a header assembly, a conveyor bridging device, a threshing and cleaning assembly, a water tank and a straw crushing device assembly. The miniature soybean combine harvester has the beneficial effects that the position and parts of the whole mechanism are regulated, so that the whole combine harvester is simple, compact, convenient to operate and high in harvesting efficiency; the combine harvester is slight in header vibration, and has a function of crushing straws for direct returning to the field, the ground clearance is smaller than 50mm, and the straws are sprayed and buried to be favorably decomposed and decayed; the combine harvester has functions of straw collection and the like, and is particularly designed for a soybean intercropping mode, the swath of a header is relatively narrow, and the harvesting speed is more than 6 to 7 acres per hour; the straws returned to the field are mixed with a mixed solution favorable for decomposition of the straws, so that the decomposition and decaying speed of the straws is increased; the harvesting productivity is as high as more than 6 to 7 acres per hour, the loss rate and the broken rate of soybeans are both not over 2 percent, and the cleaning rate of the soybeans is over 98 percent.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and particularly relates to a small soybean combine harvester. Background technique [0002] The annual harvest of soybeans (ie soybeans, the following names are interchangeable) and other grass plants such as wheat and rice often produce a lot of straw. The recycling rate of these straws is not high, and most of them are only used as biofuels. A great waste. Soybean is one of the important food crops in China. It has a history of 5,000 years of cultivation. Soybean is cultivated all over China, and its seeds are rich in plant protein. Soybeans are most commonly used to make various soy products, extract soybean oil, brew soy sauce and extract protein. Okara or ground soybeans are also commonly used in livestock feed. At present, the utilization rate of soybean straw is less than 3%. Only 6%-8% of beef cattle in the three northeastern provinces are converted from crop straw feed. A small amoun...

AI Technical Summary

Problems solved by technology

[0003] There are many types of small soybean combine harvesters in China, most of which are large and medium-sized combine harvesters, which are not suitable for medium and small plots in the southwestern hilly area, and the cost of a single machine is high, so it cannot be widely promoted in rural areas. At the same time, its soybean cleaning rate and crushing rate are relatively high, which is not very satisfactory.

In addition, there are generally two types of headers for combine harvesters, one is a non-profiling structure, and the other is mostly a suspension-type profiling mechanism. The amount of vertical adjustment of the header is not large, and it is difficult to achieve true profiling. During the harvesting process, it is easy to lose pods and bean stubble is uneven, and there is no straw cutting and collecting device behind the cleaning device, resulting in the long straw after harvesting directly returned to the field, the economic value is not fully utilized, and Long straw is not conducive to the cultivation of the soil
