Small soybean joint harvesting machine

Abstract

The invention belongs to the field of agricultural machines, and particularly discloses a small-size soybean combine harvester. The small-size soybean combine harvester comprises a harvester frame, a power device assembly, a caterpillar band walking device, a header assembly, a conveying bridge device, a threshing and cleaning assembly, a water tank and a straw smashing device assembly. The small-size soybean combine harvester has the advantages that as the position and the parts of a whole mechanism are adjusted, the whole harvester is simple, compact, convenient to operate and high in harvesting efficiency; the harvester has the functions that a header is small in vibration, the ground clearance is smaller than 50 mm, and straw is smashed to be directly returned to fields, the straw is sprayed to be buried underground, and decomposing and rotting of the straw are facilitated; the functions of collecting the straw and the like are achieved, the header of the harvester is small in cutting width and is specially designed for the soybean intercropping and interplanting mode, and the harvesting speed is higher than 6-7 mu per hour; mixed liquid beneficial for straw decomposing is mixed into the straw returned to the fields, and therefore the decomposing and rotting speed of the straw is increased. According to the small-size soybean combine harvester, the harvesting production speed is high and larger than 6-7 mu per hour, the soybean loss ratio and the soybean breakage rate are smaller than or equal to 2%, and the soybean cleaning rate is larger than 98%.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a small soybean combine harvester Background technique [0002] Harvesting herbaceous plants such as soybeans (that is, soybeans, the following names are interchangeable) and gramineous plants such as wheat and rice every year often produces a lot of straw. The recycling rate of these straws is not high, and most of them are only used as biofuels, resulting in A great waste. Soybean is one of the important food crops in China. It has been cultivated for five thousand years. Soybean is cultivated all over China. It is a crop whose 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 soybeans ground into a meal are also commonly used in livestock feed. At present, the utilization rate of soybean straw is less than 3%. Only 6%-8% of the beef cattle in the three northea...

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
