In order to further reduce the residual impurities in the grains, the grains are usually removed during the grain transportation process. For example, the Chinese patent with the announcement number CN114379994B discloses a lifting and transporting device for grain processing that can remove impurities. During the grain transportation process, the metal rotating belt will vibrate due to the high-frequency thrust, and the grain loaded inside the carrying frame will also vibrate continuously during the transportation process, which has the effect of shaking and screening, so that the grain can be screened and processed during transportation, impurities in the grain can be removed, and the purity of the grain can be improved, thereby reducing the pressure of screening work; When the existing grain lifting and transportation device is working, the impurities in the grain can be screened by the vibration of the carrying frame. However, since the grain lifting device is usually provided with a plurality of groups of carrying frames, there will be a plurality of groups of carrying frames distributed in an upper and lower parallel array in the lifting section.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 A lifting and transporting device for grain processing capable of removing impurities, comprising a body 13, a support seat 11 is fixedly connected to the lower side of the outer surface of the body 13, a feed pipe 14 is fixedly connected to the outer surface of the left end of the body 13, the outer surface of the lower end of the feed pipe 14 is fixedly connected to the upper part of the support seat 11, and a screening component is arranged inside the feed pipe 14; The screening component includes an embedded placement groove 31 opened at the lower end of the inner surface of the feed pipe 14, the placement groove 31 is connected to the inside of the support seat 11, and the front and rear ends of the inner surface of the feed pipe 14 are fixedly connected with movable rods 22, and the outer surface of the movable rod 22 is rotatably connected with a guide plate 23, the guide plate 23 is located inside the placement groove 31, and the outer surface of the upper end of the guide plate 23 is provided with an overflow groove 24.

[0020] The feed pipe 14 is inclined, the overflow grooves 24 are in several groups and distributed in a parallel array, the support seat 11 is hollow inside, the overflow grooves 24 are connected to the inside of the support seat 11, and the discharge pipe 12 is fixedly connected to the outer surface of the front end of the support seat 11.

[0021] By adopting the above technical solution, the machine body 13 is supported by the support seat 11. When corn, soybean and other grains are lifted and transported, the grains to be processed are injected into the feed pipe 14. The feed pipe 14 is inclined so that the grains roll down along the inner wall of the feed pipe 14 under the action of their own gravity. The placement groove 31 opened on the inner side of the feed pipe 14 is used to place the guide plate 23. The feed pipe 14 supports the guide plate 23 for rotation through the movable rod 22. After the grains enter the feed pipe 14, the grains will roll over the surface of the guide plate 23. At this time, small impurities such as gravel, debris and empty shells in the grains will pass through the guide plate 23. The overflow trough 24 on the surface of the support seat 11 falls into the interior of the support seat 11, so that the impurities in the grains can be separated and removed, thereby reducing the risk of secondary contamination of the grains by impurities, and the normal grains will roll into the interior of the machine body 13 under the guidance of the guide plate 23, and be lifted upward by the transportation device. By setting the screening component, the impurities in the grains can be separated and removed synchronously while ensuring the smooth feeding of the grains, thereby further improving the purity of the grains and reducing the difficulty of removing impurities from the grains. The discharge pipe 12 on the front side of the support seat 11 can take out the impurities inside the support seat 11 in time.

[0022] like Figure 2 and Figure 3 As shown, a driving assembly is arranged inside the machine body 13, and the driving assembly includes a driving shaft 18 rotatably connected to the front and rear ends of the inner surface of the machine body 13, and a driving roller 17 is fixedly connected to the outer surface of the driving shaft 18. The number of the driving shaft 18 and the driving roller 17 is two groups and they are symmetrically distributed up and down, and the outer surface of the driving roller 17 is rotatably connected to a conveyor belt 19.

[0023] The outer surface of the conveyor belt 19 is fixedly connected with a receiving hopper 20, and the number of the receiving hoppers 20 is several groups and is evenly distributed along the surface of the conveyor belt 19. The outer surface of the rear end of the body 13 is fixedly connected with a motor 16, and the front end of the output shaft of the motor 16 is fixedly connected to the upper drive shaft 18. The outer surface of the driving roller 17 is provided with an anti-skid groove 45, and the number of the anti-skid grooves 45 is several groups and is distributed in a ring array.

[0024] By adopting the above technical solution, when the transportation device is working, the motor 16 is started and the drive shaft 18 is driven to rotate synchronously through the output shaft of the motor 16, and the drive shaft 18 drives the drive roller 17 to rotate synchronously. The two groups of drive rollers 17 distributed up and down can drive the conveyor belt 19 to rotate clockwise. During the movement of the conveyor belt 19, the receiving hopper 20 on its surface will be driven to move synchronously. When the receiving hopper 20 moves to the lower side of the feed pipe 14, the grains will enter the feed hopper and move upward under the drive of the conveyor belt 19. The anti-skid groove 45 on the surface of the drive roller 17 can effectively increase the friction between the drive roller 17 and the conveyor belt 19, thereby reducing the probability of slipping between the conveyor belt 19 and the drive roller 17, and further improving the stability of the transportation device during operation.

[0025] like Figure 3 and Figure 7 As shown, a material stripping assembly is provided on the inner side of the receiving hopper 20, and the material stripping assembly includes a guide groove 32 opened on the inner surface of the receiving hopper 20, and the inner surface of the guide groove 32 is slidably connected with a guide block 33, and the number of the guide grooves 32 and the guide blocks 33 is two groups and they are symmetrically distributed, and a movable plate 34 is fixedly connected between the two groups of guide blocks 33, and the side wall of the movable plate 34 is in sliding contact with the inner surface of the receiving hopper 20.

[0026] By adopting the above technical solution, when the opening direction of the receiving hopper 20 is facing upward, the movable plate 34 will be at the bottom of the feeding hopper under the action of gravity, so that it is convenient for the receiving hopper 20 to hold the grains. As the receiving hopper 20 gradually moves upward, when the opening direction of the receiving hopper 20 rotates to the lower side, the movable plate 34 will slide downward under the action of gravity. At this time, the guide groove 32 inside the receiving hopper 20 can play a sliding guiding role for the guide block 33, so that the movable plate 34 can slide linearly along the guide groove 32. The movable plate 34 moves downward to completely discharge the grains inside the receiving hopper 20, thereby effectively reducing the grain residue inside the receiving hopper 20, and thus improving the grain transportation efficiency to a certain extent.

[0027] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, an adjustment component is provided on the inner side of the support seat 11, and the adjustment component includes a connecting shaft 28 rotatably connected to the front and rear ends of the support seat 11, and a top plate 47 is fixedly connected to the outer surface of the connecting shaft 28, and the top plate 47 is in sliding contact with the lower side of the outer surface of the guide plate 23 at one end away from the connecting shaft 28, and a knob 29 is fixedly connected to the front end of the connecting shaft 28.

[0028] The outer surface of the connecting shaft 28 is threadedly connected with a locking sleeve 30 between the knob 29 and the support seat 11, and the locking sleeve 30 is in rotational contact with the outer surface of the front end of the support seat 11. The lower side of the outer surface of the body 13 is provided with mesh holes 21, and the number of the mesh holes 21 is several groups and distributed in an arc shape. The lower end of the inner surface of the body 13 is fixedly connected with a partition plate 46, and the number of the partition plates 46 is two groups and is symmetrically distributed.

[0029] A movable groove 25 is embedded inside the guide plate 23 , and a slide rod 26 is slidably connected to the inner surface of the movable groove 25 . A top block 27 is fixedly connected to the outer surface of the slide rod 26 . The top blocks 27 are provided in several groups and are located inside the overflow groove 24 .

[0030] By adopting the above technical solution, after the grains enter the body 13 through the feed pipe 14, they will accumulate on the lower side of the inner surface of the body 13, and the impurities remaining in the grains will fall into the support seat 11 through the mesh 21 on the lower side of the body 13, so that the impurities remaining in the grains can be further screened and separated, and the partitions 46 symmetrically distributed inside the body 13 separate the inside of the body 13, so that the grains are gathered in the middle, and when the receiving hopper 20 moves to the lower side, the grains can be placed inside the receiving hopper 20, and the receiving hopper 20 will contact the grains during the movement. At this time, the movement of the receiving hopper 20 can move the grains, so that the grains can fully contact the lower end of the body 13, so that the impurities in the grains can be effectively separated; Since there are large differences in the roundness of grains such as corn and soybeans, in order to enable the grains to fall smoothly inside the feed pipe 14 and reduce the probability of grains being blocked inside the feed pipe 14, an adjustment component is provided for this purpose. When transporting and lifting grains such as soybeans with good roundness, in order to enable the grains to roll smoothly over the surface of the guide plate 23 and have sufficient time to separate impurities, the operator rotates the locking sleeve 30 to the side close to the knob 29 so that the locking sleeve 30 is out of contact with the surface of the machine body 13, and then the operator rotates the connecting shaft 28 through the knob 29, and the top plate 47 is driven to rotate through the connecting shaft 28. When the top plate 47 flips upward, the upper end of the top plate 47 will contact the lower surface of the guide plate 23 and push the guide plate 23 to flip upward with the movable rod 22 as the fulcrum. After the top plate 47 rotates to an appropriate position, the movable rod 22 is locked and fixed again by the locking sleeve 30. At this time, the horizontal angle of the upper surface of the guide plate 23 gradually becomes smaller, thereby slowing down the slope of the guide plate 23, so that the grains The rolling speed on the surface of the guide plate 23 is slowed down, and the residence time of the grains on the surface of the guide plate 23 is prolonged, so that the grains have sufficient time to separate the impurities therein, thereby improving the separation and removal quality of impurities in the grains. When processing grains such as corn, the guide plate 23 is flipped downward to increase the inclination angle of the guide plate 23, so that the corn can slide smoothly on the surface of the guide plate 23, reducing the probability of grains being blocked inside the feed pipe 14, while ensuring the operating stability of the grain lifting and transportation device, it can also greatly improve the application range of the transportation device. When the guide plate 23 is flipped over a certain angle, the slide bar 26 will slide downward along the inside of the movable groove 25 under the action of gravity. During the sliding process, the slide bar 26 will drive the top block 27 to slide inside the overflow groove 24, and the grains stuck in the overflow groove 24 can be ejected by the top block 27, thereby reducing the probability of grains blocking the overflow groove 24, thereby ensuring the effect of removing impurities in the grains.

[0031] like Figure 3 and Figure 8 As shown, a discharge pipe 15 is fixedly connected to the upper side of the outer surface of the right end of the body 13, and a dredging component is arranged on the inner side of the body 13, and the dredging component includes a receiving groove 35 opened at the right end of the inner surface of the body 13, and a core shaft 38 is fixedly connected to the inner surface of the receiving groove 35, and a receiving plate 37 is rotatably connected to the outer surface of the core shaft 38, and a capsule 36 is fixedly connected to the outer surface of the right end of the receiving plate 37, and a through hole 39 is opened on the outer surface of the right end of the body 13, and the capsule 36 passes through the through hole 39 to the outside of the body 13, and the capsule 36 is in an arc shape.

[0032] The end of the bladder body 36 away from the receiving plate 37 is fixedly connected to the outer surface of the lower end of the discharge pipe 15, the inner surface of the bladder body 36 is fixedly connected to a spring 40, a connecting pipe 48 is embedded and fixedly connected to the inner side of the receiving plate 37, a control valve is arranged inside the connecting pipe 48, a retaining groove 42 is opened at the lower end of the inner surface of the discharge pipe 15, a bladder body 2 43 is fixedly connected to the inner surface of the retaining groove 42, an air guide tube 41 is fixedly connected between the bladder body 1 36 and the bladder body 2 43, the outer surface of the lower end of the bladder body is in sliding contact with the lower end of the inner surface of the retaining groove 42, a plug plate 44 is fixedly connected to the outer surface of the bladder body, the lower end of the plug plate 44 is in sliding connection with the inner surface of the retaining groove 42, and the outer surface of the plug plate 44 is pointed.

[0033] By adopting the above technical solution, the machine body 13 is rotated to the support by the core shaft 38, and the receiving plate 37 is turned to the lower side of the receiving hopper 20 and maintained in an inclined state under the elastic force of the spring 40. When the receiving hopper 20 moves to the uppermost side with the grain carrying the grain, as the receiving hopper 20 continues to move, the grain inside the receiving hopper 20 will gradually fall downward to the surface of the receiving plate 37, and be guided to the inside of the discharge pipe 15 under the guiding action of the receiving plate 37, and then be discharged to the outside of the machine body 13 through the discharge pipe 15 for subsequent processing. During the downward movement of the receiving hopper 20, it will contact the receiving plate 37. At this time, the receiving plate 37 will be turned toward the inside of the storage groove 35 under the push of the receiving hopper 20. During the movement, the receiving plate 37 will cooperate with the discharge pipe 15 to squeeze the capsule 1 36. At this time, the gas inside the capsule 1 36 will enter the inside of the capsule 2 43 through the air guide pipe 41. The volume expansion of the capsule 2 43 will drive the plug plate 4 The hopper 20 and the receiving plate 37 are disengaged from each other, and the receiving plate 37 is turned upward and reset under the elastic force of the spring 40. The receiving plate 37 stretches the capsule 1 36 during the movement, so that the gas inside the capsule 2 43 enters the capsule 1 36 under the action of pressure, so that the capsule 2 43 drives the inserting plate 44 to slide upward and reset. The connecting pipe 48 provided on the surface of the capsule 1 36 is used for the circulation of gas inside and outside the capsule 1 36. The control valve can maintain the gas pressure inside the capsule 1 36 within an appropriate range. The discharging pipe 15 can be effectively cleared through the reciprocating movement of the inserting plate 44, so that the smoothness of the discharging of the discharging pipe 15 can be improved.

[0034] Instructions for use: When the lifting and transporting device is working, the grains to be processed are injected into the feed pipe 14. After the grains enter the feed pipe 14, the grains will roll over the surface of the guide plate 23. At this time, small impurities such as gravel, debris and empty shells in the grains will pass through the overflow groove 24 on the surface of the guide plate 23 and fall into the support seat 11. The driving roller 17 drives the receiving hopper 20 to move synchronously through the conveyor belt 19, and the grains are lifted upward by the receiving hopper 20. At the same time, the receiving hopper 20 will contact the grains during the movement. At this time, the movement of the receiving hopper 20 can move the grains, so that the grains can fully contact the lower end of the machine body 13, thereby realizing effective separation of impurities in the grains. The rotation of the top plate 47 can adjust the angle of the receiving plate 37 The grains are separated from the impurities in the grains in sufficient time, thereby improving the quality of separation and removal of impurities in the grains. The grains in the receiving hopper 20 will gradually fall downward to the surface of the receiving plate 37, and will be guided to the inside of the discharge pipe 15 by the guiding action of the receiving plate 37. The receiving plate 37 will be turned over to the inside of the storage groove 35 and squeeze the capsule 1 36 under the push of the receiving hopper 20. The gas in the capsule 1 36 will enter the inside of the capsule 2 43 through the air guide tube 41. The volume expansion of the capsule 2 43 will drive the plug plate 44 to slide along the inside of the retaining groove 42. The plug plate 44 will push and clear the grains in the discharge pipe 15 during the movement, thereby effectively reducing the probability of the grains blocking the discharge pipe 15.
