Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-3, the present invention provides the following technical solutions: a high-efficiency corn threshing machine for agricultural production comprises a supporting plate 1, wherein a threshing device is fixed on the upper surface of the supporting plate 1 in a welded mode, four supporting columns 3 are respectively fixed at four corners of the outer wall of the bottom of the supporting plate 1 in a welded mode, the supporting plate 1 is of an inclined structure, an air draft device is fixed on the upper surface of the threshing device in a welded mode, a feed inlet 2 and a guide outlet 11 are fixed on the outer walls of two opposite sides of the threshing device in a welded mode, a discharge outlet 4 is formed in one side, close to the guide outlet 11, of the bottom of the supporting plate 1, the threshing device comprises three threshing cylinders 19, an electric conveying belt 17, a motor 5, three rotating shafts 15, three displacement devices 14 and a belt 16, the three rotating shafts 15 are respectively fixed to the top ends of the three displacement devices through bearings, the three threshing cylinders 19 are respectively fixed, the top of the discharge port 4 is fixedly welded with a discharge filter screen 18.

In the embodiment of the utility model, when the corn enters the threshing device from the feed inlet 2, the threshing device threshes the corn, at the moment, the air draft device is operated to absorb and discharge scraps and dust generated during the corn threshing, the phenomenon of dust flying is avoided, the separated corn kernels are recovered through the discharge port 4, the separated corn cobs are recovered through the guide outlet 11, the corn kernels and the corn cobs are separately recovered, the production efficiency is improved, the unnecessary waste is reduced, when the corn enters the threshing device from the feed inlet 2, because the support column 3 obliquely supports the support plate 1, the corn falls under the action of gravity in the threshing machine body, and then is driven by the electric conveyor belt 17, the corn can smoothly pass through the threshing device, the motor 5 is started at the moment, the motor 5 drives the rotating shaft 15 to rotate through the belt 16, threshing cylinder 19 that is connected with axis of rotation 15 begins to rotate and threshes the operation to the maize, according to the height of threshing cylinder 19 is adjusted to the equidimension accessible displacement device 14 of maize not, can let thresher carry out effectual threshing to the maize of equidimension not, make production efficiency obtain improving, after the maize threshes through threshing device, can remove ejection of compact filter screen 18's top with the influence of self gravity through the drive of electric conveyor 17, ejection of compact filter screen 18 can effectively the separation object bigger than the kernel of corn, thereby filter the kernel of corn and advance discharge gate 4 and retrieve, just so avoided the problem that the corncob and kernel of corn are mixed together and can't effectively distinguish, the efficiency of production is improved, time is saved.

Specifically, updraft ventilator includes air exhauster 8, air outlet 10, two ventilation pipes 7, two air intakes 6, two air-out filter screen 20, and two air-out filter screen 20 welded fastening respectively are in two 6 inner walls of air intake, and two air intakes 6 weld respectively in the relative both sides outer wall of protecting crust 9, and two ventilation pipes 7 are respectively through the inner wall of screw fixation in two air intakes 6, and air exhauster 8 passes through the top of threaded fastening in protecting crust 9.

In this embodiment: when the threshing device starts to work, the exhaust fan 8 is started to exhaust air inside the protective shell 9 at the moment, dust enters the ventilation pipe 7 through the air inlet 6 and is discharged from the air outlet 10, and the air outlet filter screen 20 fixed on the inner wall of the air inlet 6 can effectively filter out corn kernels and objects larger than the corn kernels, so that unnecessary waste is avoided, and meanwhile, the dust cleaning work is facilitated.

Specifically, the bottom of the inner wall of the outlet 11 is fixed with a guide filter screen 12 through a bolt, and a baffle 13 is fixed on one side of the guide filter screen 12 far away from the protective shell 9 in a welding manner.

In this embodiment: after the corn that threshes passes through ejection of compact filter screen 18 and gets into outlet 11, because probably there is remaining kernel of corn not filtered by ejection of compact filter screen 18, so need derive filter screen 12 and filter the kernel of corn once more, baffle 13 can effectively block the kernel of corn moreover, lets the kernel of corn can not follow outlet 11 roll-off to retrieve the kernel of corn more effectively, avoided unnecessary extravagant.

The utility model discloses a theory of operation and use flow: when corn enters the threshing device from the feeding port 2, because the supporting columns 3 support the supporting plates 1 in an inclined manner, the corn falls under the action of gravity in the threshing machine body, and then is driven by the electric conveyor belt 17, the corn can smoothly pass through the threshing device, at the moment, the motor 5 is started, the motor 5 drives the rotating shaft 15 to rotate through the belt 16, the threshing roller 19 connected with the rotating shaft 15 starts to rotate and threshes the corn, the height of the threshing roller 19 can be adjusted through the displacement device 14 according to different sizes of the corn, the threshing device can effectively thresh the corns with different sizes, when the threshing device starts to work, the exhaust fan 8 is started to exhaust air inside the protective shell 9, dust enters the ventilation pipe 7 through the air inlet 6 and then is discharged from the air outlet 10, and the air outlet filter screen 20 fixed on the inner wall of the air inlet 6 can effectively filter corn kernels and objects larger, after the maize threshes through thresher, can remove the top of ejection of compact filter screen 18 with the influence of self gravity through the drive of electric conveyor 17, ejection of compact filter screen 18 can effectively the separation object bigger than the kernel of corn, thereby filter the kernel of corn into discharge gate 4 and retrieve, after the maize of threshing passes through ejection of compact filter screen 18 and gets into the export 11, because there is remaining kernel of corn not filtered by ejection of compact filter screen 18, so need derive filter screen 12 and filter the kernel of corn once more, and baffle 13 can effectively block the kernel of corn, let the kernel of corn can not follow export 11 roll-offs, thereby the kernel of corn has been retrieved more effectively, unnecessary waste has been avoided.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
