Description

Technical Field

[0001] The present invention relates to the field of transport devices, and more particularly to a lifting and transport device for grain processing capable of removing impurities. Background Art

[0002] Grains usually refer to seeds of grasses, such as wheat, rice, corn, etc. In the grain processing process, the lifting and transportation device plays a vital role. It not only improves work efficiency and reduces the tediousness and labor intensity of manual operation, but also ensures the continuity and stability of grain processing. In order to further reduce the residual impurities in the grain, the grain is usually removed during the grain transportation process.

[0003] For example, Chinese patent publication number CN114379994B discloses a grain processing and lifting and transporting device capable of removing impurities. During the grain transport process, the metal rotating belt vibrates due to the high-frequency thrust, and the grain loaded inside the carrying frame also vibrates continuously during the transport process, achieving a shaking and screening effect, so that the grain can be screened during transportation, impurities in the grain can be removed, and the purity of the grain can be improved, thereby reducing the pressure of the screening work;

[0004] When the existing grain lifting and transportation device is working, the impurities in the grain can be screened through the vibration of the carrying frame. However, since the grain lifting device is usually provided with several groups of carrying frames, there will be several groups of carrying frames distributed in an upper and lower parallel array in the lifting section. During the transportation process, as the carrying frame vibrates, some impurities will be shaken off from the upper end of the carrying frame, and some impurities will fall into the inside of the carrying frame on the lower side, thereby causing secondary contamination to the grain inside the carrying frame, which in turn affects the effect of removing impurities in the grain.

[0032] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8A lifting and transporting device for grain processing capable of removing impurities comprises a body 13, a support base 11 being fixedly connected to the lower side of the outer surface of the body 13, a feed pipe 14 being 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 being fixedly connected to the upper part of the support base 11, and a screening component being provided inside the feed pipe 14;

[0034] The screening component includes an embedded placement groove 31 opened at the lower end of the inner surface of the feed pipe 14, and the placement groove 31 is connected to the interior of the support seat 11. 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.

[0035] The feed pipe 14 is inclined, the overflow troughs 24 are in several groups and distributed in a parallel array, the interior of the support seat 11 is hollow, the overflow troughs 24 are connected to the interior 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.

[0036] By adopting the above technical solution, the machine body 13 is supported by the support seat 11. When lifting and transporting grains such as corn and soybeans, 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 rotates and supports the guide plate 23 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. 3, the overflow chute 24 on the surface falls into the interior of the support seat 11, thereby separating and removing impurities in the grains, thereby reducing the risk of secondary contamination of the grains by impurities, and 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 up the screening component, while ensuring the smooth feeding of grains, the impurities in the grains can be separated and removed simultaneously, thereby further improving the purity of the grains and reducing the difficulty of grain impurity removal. The discharge pipe 12 on the front side of the support seat 11 can remove the impurities inside the support seat 11 in time.

[0037] like Figure 2 and Figure 3 As shown, a driving assembly is provided inside the 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 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 is symmetrically distributed up and down, and the outer surface of the driving roller 17 is rotatably connected to the conveyor belt 19.

[0038] The outer surface of the conveyor belt 19 is fixedly connected to 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 to 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 drive roller 17 is provided with an anti-slip groove 45, and the number of the anti-slip grooves 45 is several groups and is distributed in a ring array.

[0039] By adopting the above technical solution, when the transport device is working, the motor 16 is started and the drive shaft 18 is driven to rotate synchronously by the output shaft of the motor 16, and the drive shaft 18 drives the drive roller 17 to rotate synchronously. The two sets of drive rollers 17 distributed above and below 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 grain will enter the feed hopper and move upward under the drive of the conveyor belt 19. The anti-skid groove 45 opened 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 thus improving the stability of the transport device during operation.

[0040] like Figure 3 and Figure 7 As shown, a stripping assembly is provided on the inner side of the receiving hopper 20, and the 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. The number of the guide grooves 32 and the guide blocks 33 is two groups and they are symmetrically distributed. 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.

[0041] 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 the receiving hopper 20 can 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 on the guide block 33, so that the movable plate 34 can slide linearly along the guide groove 32. The downward movement of the movable plate 34 can 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.

[0042] 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. 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.

[0043] 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 46, and the number of the partitions 46 is two groups and is symmetrically distributed.

[0044] 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 trough 24 .

[0045] 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 inside of the support seat 11 through the mesh holes 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 symmetrically distributed partitions 46 inside the body 13 separate the inside of the body 13, so that the grains are gathered in the middle. When the receiving hopper 20 moves to the lower side, the grains can be placed in 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, thereby effectively separating the impurities in the grains.

[0046] The hopper 23 is rotated to the right of the feeder 14 so that the feeder 14 can be rotated downwards and the feeder 14 is moved downwards to the feeder 14. The hopper 23 is rotated to the right of the feeder 14 so that the feeder 14 can be moved downwards and the feeder 14 can be moved downwards. The rolling speed on the surface of the guide plate 23 is slowed down, and the residence time of the grain on the surface of the guide plate 23 is prolonged, so that the grain has sufficient time to separate the impurities therein, thereby improving the quality of separation and removal of impurities in the grain. 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 grain being blocked inside the feed pipe 14, while ensuring the operation stability of the grain lifting and transporting device, it can also greatly improve the application range of the transporting device. When the guide plate 23 is flipped to 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 chute 24, and the grain stuck in the overflow chute 24 can be ejected by the top block 27, thereby reducing the probability of grain blocking the overflow chute 24, thereby ensuring the effect of removing impurities in the grain.

[0047] 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 provided on the inner side of the body 13. The dredging component includes a receiving groove 35 opened on 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. A receiving plate 37 is rotatably connected to the outer surface of the core shaft 38. A capsule 36 is fixedly connected to the outer surface of the right end of the receiving plate 37. 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. The capsule 36 is arc-shaped.

[0048] The end of the sac 1 36 away from the material receiving plate 37 is fixedly connected to the outer surface of the lower end of the discharge pipe 15, the inner surface of the sac 1 36 is fixedly connected to a spring 40, the inner side of the sac 37 is embedded with a connecting pipe 48, a control valve is provided inside the connecting pipe 48, the lower end of the inner surface of the discharge pipe 15 is provided with a retaining groove 42, the inner surface of the retaining groove 42 is fixedly connected to the sac 2 43, an air guide tube 41 is fixedly connected between the sac 1 36 and the sac 2 43, the outer surface of the lower end of the sac is in sliding contact with the lower end of the inner surface of the retaining groove 42, the outer surface of the sac is fixedly connected to an insert plate 44, the lower end of the insert plate 44 is in sliding connection with the inner surface of the retaining groove 42, and the outer surface of the insert plate 44 is pointed.

[0049] 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 flipped to the lower side of the receiving hopper 20 under the elastic force of the spring 40 and maintained in an inclined state. When the receiving hopper 20 moves to the uppermost side with the grains carried by the receiving hopper 20, as the receiving hopper 20 continues to move, the grains 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 guidance 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. In the process of the receiving hopper 20 moving downward, it will contact the receiving plate 37. At this time, the receiving plate 37 will flip toward the inside of the receiving groove 35 under the push of the receiving hopper 20. In the process of moving, the receiving plate 37 will cooperate with the discharge pipe 15 to squeeze the bag 1 36. At this time, the gas inside the bag 1 36 will enter the inside of the bag 2 43 through the air guide pipe 41. The expansion of the volume of the bag 2 43 will drive the plug plate 4 The hopper 20 is then disengaged from the receiving plate 37, which in turn pushes the plate 44 to the feed tube 15, thereby effectively reducing the chance of the grain blocking the feed tube 15 and ensuring the reliability of the transport device during operation. When the receiving hopper 20 is out of contact with the receiving plate 37, 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 its movement, thereby causing the gas inside the capsule 2 43 to enter the capsule 1 36 under the action of pressure, thereby causing the capsule 2 43 to drive the plate 44 to slide upward and reset. The connecting pipe 48 provided on the surface of the capsule 1 36 is used for the flow 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 reciprocating movement of the plate 44 can effectively clear the feed tube 15, thereby improving the smoothness of the discharge of the feed tube 15.

[0050] 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 inside of 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 with 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 have enough time to separate the impurities therein, thereby improving the quality of separation and removal of impurities in the grains. The grains inside the receiving hopper 20 will gradually fall down to the surface of the receiving plate 37 and be guided to the inside of the discharge pipe 15 under the guidance of the receiving plate 37. The receiving plate 37 will flip toward the inside of the storage groove 35 and squeeze the capsule 1 36 under the push of the receiving hopper 20. The gas inside 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 insert plate 44 to slide along the inside of the retaining groove 42. The insert plate 44 will push and clear the grains inside the discharge pipe 15 during the movement, thereby effectively reducing the probability of the grains causing blockage of the discharge pipe 15.
