Description

Be articulated in the paddy rice harvester-thresher on workers and peasants-12K type hand tractor

Technical field

The utility model relates to the mechanical device of a kind of paddy rice harvesting, threshing.

Background technology

Grain header in the market all be grain header itself self-powered and and running gear, cost is high, the peasant is difficult to accept; And peasant's hand tractor commonly used at present, particularly Guangdong, the widely used workers and peasants of Hunan two province peasants-12K type hand tractor, in farming operation mainly is to be used to plough a field, other purposes then seldom relates to, for example paddy rice harvesting, threshing etc., caused the waste of peasant's existing resource, though a spot of paddy rice harvester-thresher that is articulated on the hand tractor also appears at present, owing to its complex structure, inconvenience is installed and operates and dumbly limited it and further apply.

Summary of the invention

The purpose of this utility model is to provide the paddy rice harvester-thresher on a kind of workers and peasants of being articulated in-12K type hand tractor, and it utilizes workers and peasants-12K hand tractor as power and running gear, and low price is easy for installation, flexible operation.

The utility model provides is articulated in paddy rice harvester-thresher on workers and peasants-12K type hand tractor, comprise reaping apparatus and sheller unit, connect by straw-conveying groove between reaping apparatus and the sheller unit, described reaping apparatus comprises upper and lower cutter, left and right nearside divider, straw shift wheel and the ceding of Taiwan, wherein straw shift wheel is installed in the top of the ceding of Taiwan, left and right nearside divider be installed in the ceding of Taiwan the left and right sides; Described sheller unit comprises separating mechanism and paddy conveying mechanism, and the paddy conveying mechanism connects with separating mechanism; Reaping apparatus described in the utility model is fixed on the bracket assembly of hand tractor, and sheller unit is articulated on the traction support body sub-assembly of hand tractor.

As a kind of improvement of the present utility model, described upper cutter knife is positioned at the front end of the ceding of Taiwan, following cutter is positioned at the below of the ceding of Taiwan, connect by fixed mount and screw mechanism between the upper and lower cutter, screw mechanism comprises screw rod and nut, wherein upper cutter knife is installed on the fixed mount, and screw rod is fixed on down on the cutter, and nut is fixed on the fixed mount.

As further improvement of the utility model, described fixed mount is provided with the hydraulic means of realizing upper and lower cutter interlock.

During the work of this paddy rice harvester-thresher; cut off by the upper cutter knife that straw shift wheel is delivered to the ceding of Taiwan with the standing grain fringe; assembled by ceding of Taiwan screw feeder and be transported on the chain of straw-conveying groove, the chain of straw-conveying groove is transported to separating mechanism to spike of rice and carries out threshing, and the grain of taking off is sent by the paddy conveying mechanism.During the utility model paddy rice harvester-thresher harvesting paddy rice, can regulate screw mechanism between the upper and lower cutter according to the height of paddy rice makes and reaches suitable distance between the upper and lower cutter, can cut off spike of rice to ensure upper cutter knife, there is suitable gap on following cutter and ground, with the following cutter of upper cutter knife interlock remaining straw is cut off, retained the rice stubble of proper height on the ground.

Because reaping apparatus and the related parts of sheller unit in the utility model all have unified national standard, therefore can reequip existing workers and peasants-12K type hand tractor, install simple, easy to operate, has advantages of high practicability, both can alleviate peasant's financial burden, can alleviate peasant's labour intensity again; And the utility model adopted the secondary cut device, and cutting height can regulate, when both having solved harvesting because of cutting a batch too high problem that influences subsequent job; satisfied agriculture requirement; reduce the extra power burden of separating mechanism again, power consumption is distributed rationally, had stronger economy.

Below in conjunction with the drawings and the specific embodiments the utility model is further described.
