[0014] Beneficial effects

[0015] The utility model provides a vertical elevator for grain processing. Compared with the existing technology, it has the following advantages:

[0016] (1) The vertical elevator for grain processing can be used to remove impurities and dust in the grain before the grain is lifted. The grain can be poured into the first filter frame first. The first filter frame filters some larger impurities, and the grain will fall into the second filter frame. Then the motor is turned on, and the motor drives the spiral blade to rotate. The spiral blade drives the driving wheel to rotate. The driving wheel drives the rotating rod and the cam to rotate through the belt and the driven wheel. During the rotation process, one end of the cam will squeeze the extrusion plate, thereby causing the first filter frame and the slide bar to move. When the cam rotates to the other end, it stops squeezing the extrusion plate. The first filter frame is pressed, and the sliding rod and the first filter frame are reset under the action of the spring force. As the cam rotates continuously, the first filter frame and the second filter frame are shaken, thereby improving the rate of grain filtering and preventing grain from being blocked in the first filter frame. Grain that falls into the second filter frame will stay on the inclined plate, and as the second filter frame shakes, the grain will roll into the material guide inclined frame, while smaller impurity particles will fall to the bottom of the box through the second leakage hole. Through the double screening and filtration of the grain, the content of impurities in the grain is reduced, and the quality of subsequent processing of the grain is improved.

[0017] (2) The vertical elevator for grain processing can close the sealing door when the grain is being screened and filtered, thereby preventing the dust generated during the grain filtering process from spreading into the air in large quantities. At the same time, since the filtration can filter out small particles of impurities in the grain, the dust generated during the grain lifting process is also reduced.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: a vertical elevator for grain processing, comprising a base 1, a top end of which is provided with a lifting component 2 and a filtering component 3;

[0028] The lifting assembly 2 includes a lifting cylinder 21, which is fixedly connected to the base 1;

[0029] The filter assembly 3 includes a box body 31, which is fixedly connected to the base 1. A second filter frame 35 is provided inside the box body 31. The first filter frame 33 is fixedly installed on the top of the second filter frame 35. Two slide bars 37 are fixedly installed on both sides of the outer wall of the second filter frame 35. One end of the outer wall of the four slide bars 37 is movable through the inner wall of the box body 31. An inclined plate 36 is fixedly installed on the bottom end of the inner wall of the second filter frame 35. The grain on the inclined plate 36 will gradually slide down. A sliding plate 318 is fixedly installed on the inner wall of the second filter frame 35. The grain falling from the first filter frame 33 will Falling on the sliding plate 318, the sliding plate 318 has a certain inclination angle, which will cause the grain to slide down from the higher part of the inclined side of the inclined plate 36, so that the grain can slide down and filter from the higher part of the inclined plate 36, thereby improving the filtering effect of the grain on the inclined plate 36. The outer walls of two of the four sliding rods 37 are provided with springs 38, and one end of the outer walls of two of the four sliding rods 37 is fixedly installed with an extrusion plate 39. The sliding rods 37 can support the second filter frame 35 and the first filter frame 33, and enable the first filter frame 33 and the second filter frame 35 to swing left and right.

[0030] A spiral blade 22 is rotatably installed on the inner wall of the lifting cylinder 21. The bottom end of the spiral blade 22 passes through the bottom end of the base 1 and is fixedly installed with a driving wheel 25. A motor 23 is fixedly installed on the top of the lifting cylinder 21. The output end of the motor 23 passes through the inner wall of the lifting cylinder 21 and is fixedly connected to one end of the outer wall of the spiral blade 22. When the motor 23 is turned on, it can drive the spiral blade 22 to rotate, thereby lifting the grain, and at the same time it can also drive the driving wheel 25 to rotate. The outer wall of the lifting cylinder 21 is fixedly connected to a discharge pipe 24.

[0031] Figures 1-6 A second embodiment is shown, which mainly differs from the first embodiment in that one end of the two springs 38 is fixedly connected to the outer wall of the second filter frame 35, and the other end of the two springs 38 is fixedly connected to the inner wall of the box body 31. The top of the box body 31 is hingedly connected with a sealing door 32. The spring 38 can reset the extrusion plate 39, the second filter frame 35 and the slide rod 37. Closing the sealing door 32 can prevent the dust generated during the grain filtering process from diffusing into the air in large quantities.

[0032] A group of first leakage holes is opened through the bottom end of the inner wall of the first filter frame 33, and a group of second leakage holes is opened through the bottom end of the inner wall of the inclined plate 36 and the second filter frame 35. The diameter of the first leakage holes is larger than the diameter of the second leakage holes. The first leakage holes and the second leakage holes are set with appropriate diameters so that grain can fall from the first filter frame 33, while larger impurities stay in the first filter frame 33, so that grain can stay in the second filter frame 35, and smaller impurity particles can fall from the second filter frame 35, thereby improving the filtering and screening effect of grain.

[0033] The outer wall of the base 1 is fixedly installed with a mounting plate 310, and a rotating rod 311 is rotatably installed on the top of the mounting plate 310. The bottom end of the rotating rod 311 passes through the bottom end of the mounting plate 310 and is fixedly installed with a driven wheel 313. The outer walls of the driven wheel 313 and the driving wheel 25 are provided with a belt 314. The top of the rotating rod 311 is fixedly installed with a cam 312. When the driving wheel 25 rotates, the rotating rod 311 and the cam 312 can be driven to rotate through the belt 314 and the driven wheel 313. The cam 312 will squeeze the extrusion plate 39 during rotation. As the cam 312 continues to rotate, the first filter frame 33 and the second filter frame 35 will swing left and right, thereby improving the filtering rate of the grain.

[0034] A material guide inclined frame 315 is fixedly installed on the outer wall of the second filter frame 35, and a material discharge pipe is fixedly connected to the inner wall of the material guide inclined frame 315. A material holding box 316 is arranged below the material discharge pipe. The opening of the material holding box 316 has a certain length so that the material discharge pipe will not collide with the material holding box 316 when it shakes. A material delivery pipe 317 is fixedly inserted on one side of the outer wall of the box body 31. One end of the material delivery pipe 317 is fixedly connected to the material holding box 316, and the other end of the material delivery pipe 317 is fixedly connected to the lifting cylinder 21. The material delivery pipe 317 can transport grain to the inside of the lifting cylinder 21.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] When working, before the grain is lifted, in order to remove impurities and dust in the grain, the grain can be poured into the first filter frame 33 first, and then the sealing door 32 is closed to prevent the dust generated during the grain filtering process from spreading into the air. The first filter frame 33 filters some larger impurities, and the grain will fall onto the sliding plate 318, and then the grain on the sliding plate 318 will slide into the second filter frame 35. At the same time, the motor 23 is turned on, and the motor 23 drives the spiral blade 22 to rotate, and the spiral blade 22 drives the driving wheel 25 to rotate. The driving wheel 25 drives the rotating rod 311 and the cam 312 to rotate through the belt 314 and the driven wheel 313. During the rotation, one end of the cam 312 will squeeze the squeezing plate 39, thereby moving the first filter frame 33 and the sliding rod 37. When the cam 312 rotates to the other end, it stops squeezing the squeezing plate 39. At this time, the sliding rod 37 and the first filter frame 33 will be reset under the action of the elastic force of the spring 38. As the cam 312 continues to The rotation causes the first filter frame 33 and the second filter frame 35 to shake, thereby increasing the rate of grain filtering and preventing grain from being blocked in the first filter frame 33. Then, the grain falling into the second filter frame 35 will stay on the inclined plate 36. As the second filter frame 35 shakes, smaller impurity particles will fall to the bottom of the box body 31 through the second leakage hole. By screening the grain twice, the impurity content in the grain is reduced, and the quality of subsequent processing of the grain is improved. The inclined plate 36 has a certain inclination angle, so the grain will roll into the guide inclined frame 315. The grain in the guide inclined frame 315 will fall into the material box 316 through the discharge pipe, and then the grain in the material box 316 will slide into the lifting cylinder 21 through the feed pipe 317. The grain is lifted by the rotation of the spiral blade 22 and then discharged into the external environment from the discharge pipe 24. Since the filtration can filter out small particles of impurities in the grain, the dust generated by the grain during the lifting process is also reduced.
