Description
Technical Field
The utility model relates to the field of agricultural machinery, concretely relates to novel cleaning device of corn thresher.
Background
The corn thresher is an agricultural machine widely applied in China, can complete the operations of continuous feeding, threshing, cleaning and lifting output of corn cobs at one time, has high separation efficiency, saves time and labor, and gradually replaces manpower. The corn thresher is provided with a lifter at the tail end of the operation, is used for outputting the threshed corn particles to positions such as a transport vehicle, a warehouse and the like, has flexible output, can continuously work on line, and reduces manual carrying work, as shown in a notice No. CN 206472518U of a grain and bean harvester with an automatic rotating device at a grain outlet of the lifter.
The corn off-line machine realizes the separation of corn kernels and most of impurities, but still has light impurities such as partial corn leaves, fluff and the like which are not completely separated out, and the residual impurities can be separated and fall off and the corn kernels are damaged along with the conveying of the hoister, so that the quality of the finished corn kernels is influenced to a certain degree.
Disclosure of Invention
The utility model discloses to current problem, further provide a take dust extraction's lifting machine, maize seed grain is rolling the in-process promoting, and impurity and seed grain separation are more abundant, increase impurity cleaning separation at this in-process, and the impurity rate that contains of reduction maize that can be further improves the quality of maize, designs dust extraction simultaneously, improves the separation effect.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a lifting machine with a grain outlet provided with a dust suction device comprises a lifting machine main body, wherein a grain outlet of the lifting machine main body is provided with an air suction port, the air suction port is communicated with a dust suction fan device on the side edge, and impurities are discharged through an air suction pipeline; the top position of lifting machine main part is equipped with the lifting machine upper shaft, and the rotation of lifting machine upper shaft links dust absorption fan device.
The scheme of the utility model can also be:
the linkage of the upper shaft of the hoister and the dust absorption fan device is transmitted through a chain.
And a speed change gear assembly is also arranged between the upper shaft of the hoister and the chain.
The bottom end of the air suction pipeline is provided with a sundry collecting device.
The impurity collecting device is a cloth bag.
The dust absorption fan device is connected with the air suction pipeline through a soft connection structure.
The utility model discloses a go out grain mouth and take dust extraction's lifting machine, at the last operation stage of corn thresher operation, in the corn grain promotes output process promptly, cleans the separation once more to impurity, improves the quality of maize. The dust collection device is driven by the power output of the lifting upper shaft, and the mechanism is skillfully designed; in addition, the dust suction device is close to the grain outlet, so that the air suction efficiency is high and the effect is good. The device has reasonable and practical structure, and has better market competitiveness compared with similar products in the market.
Drawings
FIG. 1 is a schematic view of a three-dimensional structure of a hoist with a dust collector of the present invention;
fig. 2 is a schematic view of the three-dimensional structure of the power mechanism of the dust suction device of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a lifting machine with a grain outlet provided with a dust suction device comprises a lifting machine main body 8, wherein a grain outlet 7 of the lifting machine main body 8 is provided with a suction port 1, the suction port 1 is communicated with a dust suction fan device 2 on the side edge, and impurities are discharged through a suction pipeline 3; the top position of the hoister main body 8 is provided with a hoister upper shaft 5, and the rotation of the hoister upper shaft 5 is linked with the dust collection fan device 2.
The linkage of the upper shaft 5 of the hoister and the dust absorption fan device 2 is transmitted through a chain 6 and can also be driven through a belt or a connecting rod structure. As shown in fig. 2, a speed change gear assembly 9 is further provided between the elevator upper shaft 5 and the chain 6. The speed change gear assembly 9 can be used for adjusting the wind power of the dust collection fan device 2. When the rotating speed ratio of the speed change gear assembly 9 is fixed, the suction force of the corresponding dust collection fan device 2 corresponds to the feeding speed of the elevator main body 8.
The dust absorption fan device 2 is arranged on the side edge of the grain outlet 7, has no turning channel and is close to the air suction port 1, the loss of suction force in the conveying process is less, and the efficiency is high.
The bottom end of the air suction pipeline 3 is provided with a sundries collecting device 4. The impurity collecting device 4 is a cloth bag or a collecting bag and can collect impurities; the impurity collector 4 may be an impurity discharge port.
The dust absorption fan device 2 is connected with the air suction pipeline 3 through a soft connection structure 10. The flexible connection structure 10 facilitates assembly and disassembly of the air suction pipeline, and meanwhile, the flexible connection structure 10 has the advantages of shock resistance, deviation correction and the like.
In the front end operation process of the corn off-line machine, the separation of corn kernels and most of impurities is realized, but light impurities such as partial corn leaves and fluff are not completely separated, and the residual impurities can be separated and fall off along with the conveying of the hoister, and the corn kernels are damaged, so that the quality of the finished corn kernel products is influenced to a certain extent. By adding the dust collection fan device 2 in the final output promotion process, light impurities such as corn leaves and fluff in corn grains can be removed more effectively, the impurity content of the corn grains is further reduced, and the corn quality is improved.
The utility model discloses a go out grain mouth and take dust extraction's lifting machine has the function of further cleaning, in addition, this device structural design is reasonable practical, and like product market competition is strong.
