Description

Main cleaning sieve with dust sliding port

Technical Field

The utility model relates to the field of agricultural mechanical equipment, in particular to a main sorting screen structure of a corn thresher.

Background

The corn thresher is widely applied agricultural equipment in China, replaces manual corn threshing treatment, and is high in separation efficiency and good in impurity removal effect. During the operation process of the corn thresher, the threshed grains are cleaned and separated through the cleaning sieve, the separated snow, impurities and the like are discharged from the bottom of the cleaning sieve, after the corn thresher is operated for a long time, the snow and the impurities are accumulated at the bottom of the cleaning sieve to influence the screening effect, and the thresher needs to be moved or manually cleaned, which is troublesome. The threshing machine in the prior art is provided with a snow removing device at the bottom, can collect screened snow and impurities in a centralized manner and then discharge the collected snow and impurities out of the threshing machine through an impurity discharge port, and is similar to a structure of 'an impurity pushing device of a threshing machine' with the bulletin number CN 208821252U.

Disclosure of Invention

The utility model provides an above-mentioned condition, improve prior art's structure, provide a main cleaning sieve of smooth dirt mouth in area, solve the problem that cleaning sieve bottom snow remover structure is complicated, the fault rate is high through panel shape structure and single hank dragon device, simplify the structure, reduce cost has improved work efficiency in operation process, maintains simply.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a main cleaning sieve with a dust sliding port comprises a cleaning sieve main body on a corn thresher, wherein a first snowboard with an inclined surface part is arranged at the bottom of the cleaning sieve main body, and the first snowboard is connected with a second snowboard; the lower sides of the first snowboard and the second snowboard are connected with a single-twist dragon snow remover.

The utility model discloses technical scheme can also:

the edge of the shell of the single-twist dragon snow remover is connected with the first snowboard and the second snowboard.

The second snowboard is a horizontal board and is connected with the first snowboard through a triangular connecting board.

The second snowboard is not a horizontal board.

The first snowboard and the second snowboard are of an integrated structure.

The single-auger snow remover is connected with the snow throwing port.

The utility model discloses a main cleaning sieve of area smooth dirt mouth through increasing ski board structure to combine with single hank dragon device, solve the problem that prior art's cleaning sieve bottom snow remover structure is complicated, the fault rate is high, simplify structure reduce cost, maintain simply, improved work efficiency in operation process, make the product have market competition.

Fig. 1 is a schematic perspective view of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figure 1, the main cleaning screen with the dust sliding port comprises a cleaning screen main body 1 on a corn thresher, a first snowboard 3 with an inclined surface part 30 is arranged at the bottom of the cleaning screen main body 1, and the first snowboard 3 is connected with a second snowboard 4; the lower sides of the first snowboard 3 and the second snowboard 4 are connected to the single auger snow remover 2.

In the operation process of the main cleaning sieve of the corn thresher, snow, impurities and the like fall into the skis 1 and 2 at the lower part through the three-layer sieve and the four-layer sieve, slide into the single-auger snow remover 2 under the action of reciprocating vibration of the cleaning sieve, and are finally thrown out of the thresher body through the snow throwing port 8. The snowboard 1 and the snowboard 2 play a role of receiving and guiding and accumulating snow and foreign matters and the like.

The first snowboard 3 and the second snowboard 4 and the single auger snow remover 2 form the bottom of the cleaning screen body 1, and receive all the impurities falling from the upper part.

The edge of the shell 20 of the single auger snow remover 2 is connected with the first snowboard 3 and the second snowboard 4 in a seamless splicing mode, or in an up-and-down bearing structure or a barb butt joint structure and the like. Under the concentrated guiding action of the snowboard 1 and the snowboard 2 on impurities, the impurities fall into the single auger snow remover 2, and the single auger snow remover 2 pushes the impurities to one direction and throws the impurities out through the snow throwing port 8.

The single-auger snow remover 2 is connected with the snow throwing port 8.

In the figure, the second snowboard 4 is a horizontal plate and is connected with the first snowboard 3 through a triangular connecting plate 7 to form a platform with a drop height for receiving impurities. The second snowboard 4 may also be a non-horizontal board.

The second snowboard 4 is detachably connected with the triangular connecting plate 7 through bolts.

The snowboard 1 and the snowboard 2 are fixedly connected with the sorting screen main body 1, and the sorting screen vibrates reciprocally to drive the snowboard 1 and the snowboard 2 to vibrate reciprocally together.

The first snowboard 3 and the second snowboard 4 may also be snowboards of an integrated structure having a uniform inclination angle, and the lower end edge is connected to the housing 20 of the snow remover 2.

The utility model discloses a main cleaning sieve of area dust slipping port through increasing ski board structure to combine with single hank dragon device, solve the problem that prior art's cleaning sieve bottom snow remover structure is complicated, the fault rate is high, simplify structure reduce cost, maintain simply, improved work efficiency in operation process, the product of this structure has market competition.
