Abstract

The utility model relates to a soybean harvesting device for a knapsack combine harvester, which is composed of a front bracket, a header, a U-shaped fork, etc. The utility model is characterized in that a regulating spring is connected between the header and the front bracket, and the height of the U-shaped fork can be regulated. The utility model accomplishes directly harvesting soybeans by a combine harvester, and the harvesting efficiency is high. The cut stubbles are low, and the utility model has no soil blocks. After the position of the U-shaped fork is changed, the utility model can also harvest rice, wheat, etc. The utility model is widely used in soybean harvesting places with various landforms.

Description

Backpack combine soybean reaping apparatus

The utility model relates to a kind of agricultural harvest machinery, particularly a kind of backpack combine soybean reaping apparatus.

When external large-scale combine was gathered in the crops soybean, low cutting stubble just fell, but its header profiling operation, but structure is complicated, compares with the backpack associating cutting mill of China, and difference is very big, can't indiscriminately imitate employing.Since the nineties, the backpack combine that with the wheel tractor is power has had bigger development in China, peak annual output reaches more than 30,000, all is based on the results wheat, has developed the backpack combine based on the rubber belt track chassis of harvesting paddy rice in recent years again.These types quantitatively become the main body of China's combine owing to simple in structure, easy to use, low price, and this situation also can be kept significant period of time.But the problem of this class type results soybean fails to solve so far.Some unit once directly gathered in the crops soybean with the backpack combine, gathered around that soil is serious, loss is very big, at all can't operation.

The purpose of this utility model is to provide a kind of nothing to gather around soil, it is low to cut stubble, and can directly gather in the backpack combine soybean reaping apparatus of soybean.

The technical solution that realizes the utility model purpose is: a kind of backpack combine soybean reaping apparatus, comprise header, U-shaped fork, fore-stock, fore-stock and main frame are connected, header is connected with fore-stock by the U-shaped fork, it is characterized in that: between header and the fore-stock, also be connected with spring, an end of spring is connected with the back upper end of header, and the other end is connected with the upper end of fore-stock with adjusting nut by adjusting screw(rod).

Principle of the present utility model is: utilize the pulling force of spring, the weight of header is transferred on the fore-stock, finally drop on tire or the crawler belt, realize the profiling operation; When header was reduced to minimum cutting height, the angle of header and ground level was about 5 °, and the unlikely soil of gathering around has guaranteed the grain header normal operation.

The utility model is compared with existing technology, and its remarkable advantage is:

1, the hand harvest soybean must through cutting, transport, take off, clean, multiple working procedure such as cane processing, labour intensity is big, loss is big, labor intensive is many, uses the utility model and can once solve soybean mechanized harvest problem;

2, owing to fall low cutting stubble and keep the header front end to upwarp, reduced the loss that header causes to greatest extent;

3, open up the new purposes of backpack combine, improved the availability of this class type;

4, do not have in the harvesting process and gather around native phenomenon, harvesting efficiency height.

Accompanying drawing is a kind of structural representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described.

In conjunction with the accompanying drawings, backpack combine soybean reaping apparatus of the present utility model is by header 1, spring 2, adjusting screw(rod) 3, adjusting nut 4, U-shaped fork 5, fore-stock 6 is formed, spring 2 front ends hang over the header back upper place, the rear end is fixed on 6 ends of fore-stock by adjusting screw(rod) 3, fore-stock is connected on the main frame, utilize spring tension, to realize the profiling effect of header, power transmission shaft 7 on the power transmission shaft bearing of U-shaped fork 5 and header bottom is connected, but its height up-down adjustment, highly reduce to bottom line when cutting soybean, reduce the cutting loss to greatest extent, guarantee header and ground formation angle α=about 5 ° simultaneously, so that header can have slightly on the uneven ground and can pass through smoothly, the unlikely soil of gathering around just can prevent that also the beans after the beans folder is blown from rolling out header, reduces the loss once more.When receiving the rice wheat, the U-shaped shape can be transferred to a high position.

Claims

1, a kind of backpack combine soybean reaping apparatus, comprise header [1], U-shaped fork [5], fore-stock [6], fore-stock and main frame are connected, header flexibly connects by U-shaped fork and fore-stock, it is characterized in that: between header and the fore-stock, also be connected with spring [2], an end of spring is connected with the back upper place of header, and the other end is connected with the upper end of fore-stock with adjusting nut [4] by adjusting screw(rod).

2, backpack combine soybean reaping apparatus according to claim 1 is characterized in that being provided with two groups at spring [2].
