When the rice inside the bottom bin is piled up too much, the gravity of the rice will cause the inner plate and the partition to deform, and drive the two elastic parts at the bottom to deform, so that the volume inside the bottom bin becomes larger, and thus the feeding channel will not be blocked. Not only can the blockage inside the bin be effectively prevented, but there is no need to open a discharge port to pour the rice into the inside of the feeding channel again, thereby improving the working efficiency of the elevator.

Description

Technical Field

[0001] The invention relates to the field of rice production, in particular to a bucket elevator for rice production. Background Art

[0002] Rice, which we usually call rice, is the food obtained after a series of processing steps such as cleaning, husking (husking), milling and sorting. In the rice production process, the rice needs to be transported to the rice milling machine to remove the husk. Since the feeding port of the rice milling machine is usually located above the machine, bucket elevators are widely used in the process of feeding rice.

[0003] However, there is a common problem in the existing bucket elevator when conveying rice. Since the bucket diameter of the bucket elevator is usually smaller than the space diameter of the bottom silo, the rice is easy to fall into the transmission bin at the bottom of the elevator through the gap between the bucket and the bottom silo during the conveying process. The internal space of the bottom silo is relatively large, making it difficult for the fallen rice to be directly conveyed to the feed channel. It is usually necessary to open a discharge port on the front of the silo, collect it in a container, and then pour it into the feed channel manually, which is not only inefficient but also cumbersome to operate. In addition, if you try to reduce the internal space of the bottom silo to reduce the falling of rice, it is easy to cause the rice to be blocked in the channel, and it is necessary to stop the machine for unblocking, which will also affect the production efficiency. Therefore, the present invention provides a bucket elevator for rice production to meet the needs. Summary of the invention

At the same time, the hopper with grabbing teeth will grab the rice on the top for loading during the transmission process. When the weight of the material in the silo decreases, the No. 1 elastic part and the No. 2 elastic part will drive the inner plate and the partition to reset, so that the rice inside is supported, and the hopper can then grab the material at the bottom for loading, which can not only effectively prevent the silo from being blocked, but also eliminate the need to open a discharge port to pour the rice into the feed channel again, thereby improving the working efficiency of the elevator.

[0017] By providing the second elastic member, when a large amount of rice is piled on the top of the partition during use, the first bending portion and the second bending portion will bend at the same time, and the bending part of the first bending portion will abut against the bottom of the abutting portion, and the bending part of the second bending portion will abut against the bottom of the silo, so as to further support the partition, and effectively prevent the elastic member from being completely broken when the rice is heavy, thereby effectively improving the service life of the elastic member;

[0018] By setting a tensioning assembly, the distance between the two transmission wheels can be adjusted during actual use, thereby ensuring that the tension of the transmission belt is within a reasonable range. This design can ensure the continuity and stability of rice transportation, reduce failures and downtime caused by loose or over-tight transmission belts, and further improve the operating efficiency and reliability of the elevator.

[0031] The rice production bucket elevator provided by the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

A hopper 14 is provided, a transmission motor 8 is fixedly installed on one side of the top bin 4, a driving wheel 9 is fixedly connected to the output shaft of the transmission motor 8, a driven wheel 11 is fixedly connected to the outside of the top rotating shaft 15, and the driven wheel 11 is connected to the driving wheel 9 through a connecting belt 12. The bottom bin 1 and the top bin 4 are fixedly connected to the outside of the protective cover 6. The connection of the transmission belt 13 of the hopper 14 is provided with two square connection holes 144. A storage part 141 is provided inside the hopper 14, and a grabbing tooth 142 is fixedly connected to one end of the storage part 141. The bottom of the grabbing tooth 142 is fixedly connected to one side of the hopper 14 through multiple reinforcing ribs 143. The hopper 14 is an integrated structure. The rice is first evenly introduced into the bucket elevator through the feeding channels 2 on both sides of the bottom bin 1. The design of the feeding channel 2 ensures that the rice can smoothly enter the bottom bin 1, preparing for subsequent grabbing and transportation. The transmission motor 8 is started, and the motor drives the driving wheel 9 to start rotating. The driving wheel 9 is connected to the driven wheel 11 on the top rotating shaft 15 through the connecting belt 12, thereby driving the two transmission wheels 10 to rotate synchronously, and the transmission belt 13 on the transmission wheel 10 moves accordingly, driving the multiple hoppers 14 fixed between the transmission belts 13 to start circulating motion. When the hopper 14 swings downward, the grabbing teeth 142 inside it will penetrate into the rice pile, effectively grab the rice and bring it into the storage part 141. As the transmission belt 13 continues to move, the hopper 14 carries the rice and rises upward along the feeding channel 3 until it reaches the top bin 4.During this process, the hopper 14 always remains stable to ensure that the rice will not scatter or overflow. When the hopper 14 moves to the top bin 4, due to the change in direction of the transmission belt 13, the hopper 14 begins to flip, and the rice is poured out of the hopper 14 and flows out through the discharge channel 5 on one side of the top bin 4. The rice is transported to the subsequent production link through the discharge channel 5 to complete the entire lifting and transportation process. The discharge channel 5 is provided with an inspection door 7, which is convenient for the staff to carry out daily maintenance and cleaning inside to ensure the normal operation of the equipment. The bucket elevator realizes the continuous grabbing, lifting and unloading process of rice, greatly improves production efficiency, reduces the time and cost of manual handling, completely replaces the heavy work of manual handling of rice, reduces the labor intensity of workers, and improves the comfort of the working environment. The structure is stable, the equipment is reasonably designed, the structure is stable and reliable, the operation is simple and convenient, and it is easy to maintain and clean daily. The grabbing teeth 142 and the storage part 141 of the hopper 14 are reasonably designed, which can effectively grab and store rice and reduce the loss of rice during transportation.

[0033] In this embodiment, if Figures 1 to 4The tensioning assembly shown in the figure is used to adjust the tightness of the transmission component in the feeding assembly. The tensioning assembly is connected to the bottom bin 1. The tensioning assembly includes two moving plates 17 slidably connected to the outside of the bottom bin 1. The insides of the two moving plates 17 are fixedly connected with bearings 16. The two ends of the rotating shaft 15 inside the bottom bin 1 are respectively rotatably connected to the insides of the two bearings 16. The outside of the bottom bin 1 is threadedly connected with two threaded rods 18. One end of the two threaded rods 18 is respectively rotatably connected to the outside of the two moving plates 17. The other ends of the two threaded rods 18 are fixedly connected with hexagonal nuts. The tensioning assembly includes two moving plates 17 slidably connected to the outside of the bottom bin 1. , a bearing 16 is fixed inside each moving plate 17, and both ends of the rotating shaft 15 inside the bottom bin 1 are connected to the two moving plates 17 through the bearings 16 respectively. In the initial state, the tightness of the transmission component (such as the transmission belt 13) is within the preset appropriate range. When the tightness of the transmission component needs to be adjusted, the operator rotates the hexagonal nuts at one end of the two threaded rods 18. The threaded rods 18 are threadedly connected to the outside of the bottom bin 1. Rotating the nuts will drive the threaded rods 18 to rotate and move along the outside of the bottom bin 1. Since the other end of the threaded rod 18 is rotatably connected to the outside of the moving plate 17, the moving plate 17 will slide with the movement of the threaded rod 18, and the moving plate 1 The sliding of the bearing 16 and the two ends of the rotating shaft 15 connected thereto will drive the movement, thereby changing the tightness of the transmission component. When the tightness of the transmission component reaches the preset appropriate range, the operator stops turning the nut to complete the adjustment of the tightness. The tensioning assembly adjusts the tightness of the transmission component through the principle of threaded transmission and sliding connection. The nut at one end of the threaded rod 18 is turned to move the threaded rod 18 through threaded transmission. The movement of the threaded rod 18 is connected to the rotation of the moving plate 17, so that the moving plate 17 slides along the outside of the bottom bin 1. The sliding of the moving plate 17 drives the two ends of the rotating shaft 15 to move, thereby changing the tightness of the transmission component. The operator The operator can adjust the tightness of the transmission component by simply turning the nut to achieve flexible control. It is suitable for rotating shafts 15 of different lengths and positions, has strong adaptability, and accurately adjusts the tightness of the transmission component to ensure that the transmission component maintains stable tension and transmission efficiency during operation, reducing failures and downtime caused by too loose or too tight transmission components. Appropriate tightness can reduce wear and damage of transmission components, extend their service life, reduce maintenance costs, and improve the overall economic benefits of the equipment. The adjustment process is simple and clear, does not require complicated operations or tools, reduces operating difficulty and skill requirements, and improves the work efficiency and convenience of operators.

[0034] In this embodiment, if Figures 1 to 8The adjustment component shown is used to adjust the storage space inside the bottom bin 1. The adjustment component is connected to the bottom bin 1. Two inner plates 20 are fixedly connected to the bottom bin 1 below the two feeding channels 2. The two inner plates 20 are slidably connected to the insides of the two inner plates 20. The two extension plates are fixedly connected by a partition 21. The two inner plates 20 and the partition 21 are both plates with a certain curvature. The bottoms of the two inner plates 20 are fixedly connected to the bottom of the inner cavity of the bottom bin 1 by an elastic member No. 1 22. The bottom of the partition 21 is fixedly connected to the bottom of the inner cavity of the bottom bin 1 by two symmetrically arranged elastic members No. 23. The elastic member No. 1 22 is a curved plate. One side of the elastic member No. 22 is provided with an arc-shaped portion No. 221. The other side of the elastic member No. 22 is provided with an arc-shaped portion No. 221. A second arc-shaped portion 222 is arranged on the side, the thickness of the first elastic member 22 is a metal plate of 2cm-5cm, the height of the second arc-shaped portion 222 is greater than the height of the second arc-shaped portion 222, a first bending portion 231 is arranged on one side of the second elastic member 23, and a second bending portion 232 is arranged on the other side of the second elastic member 23, the second elastic member 23 is fixedly connected to the partition 21 by a connecting portion 233, and a resistance portion 234 is arranged at the bottom of the connecting portion 233, the protrusion direction of the first bending portion 231 is toward the bottom of the resistance portion 234, and the protrusion direction of the second bending portion 232 is toward the bottom of the inner cavity of the bottom bin 1, the thickness of the second elastic member 23 is a metal plate of 2cm-5cm, and during use, when rice is poured into the inner part of the feeding channel 2 After that, most of the rice will directly enter the interior of the hopper 14 and be transported upward, while a small part of the rice will flow into the interior of the bottom bin 1 through the gap between the hopper 14 and the bottom bin 1, and will flow to the top of the two inner plates 20 and the partition 21 along the channel, and accumulate on the top of the two inner plates 20 and the partition 21. During the operation of the feeding assembly, the rice on the top of the inner plates 20 and the partition 21 will be grabbed by the grabbing teeth 142 of the moving hopper 14 for feeding. When too much rice is accumulated on the top of the inner plates 20 and the partition 21, the gravity of the rice itself will squeeze the inner plates 20 and the partition 21, causing the inner plates 20 and the partition 21 to deform, and the partition 21 moves downward, while the two inner plates 20 move to both sides, causing the inner plates 20 and the partition 21 to move downward. The extension plate will be pulled out, thereby expanding the space inside the bottom bin 1 to prevent excessive accumulation of rice and blockage. In the process of the inner plate 20 and the partition 21 being deformed by force, the No. 1 elastic member 22 and the No. 2 elastic member 23 will be deformed by force at the same time, and the two arc-shaped portions of the No. 1 elastic member 22 will be deformed at the same time, so that the No. 1 elastic member 22 will be bent at the two arc-shaped portions, and at the same time, the two bent portions of the No. 2 elastic member 23 will also be deformed and bent, so that the inner plate 20 and the partition 21 can expand outward. When the rice is heavier, the No. 1 bent portion 231 of the No. 2 elastic member 23 will contact the resistance portion 234 after bending, and provide auxiliary support to the top partition 21, so as to disperse the pressure on the entire No. 2 elastic member 23.This can prevent the problem of the second elastic member 23 being broken due to the large extrusion force. At the same time, when the hopper 14 continuously transports the rice on the top of the inner plate 20 and the partition 21, the weight of the rice on the top of the inner plate 20 and the partition 21 will be reduced, so that the first elastic member 22 and the second elastic member 23 can reset the inner plate 20 and the partition 21 and prop up the rice on the top of the inner plate 20 and the partition 21, thereby ensuring that the hopper 14 can take away a part of the rice every time it passes the bottom of the inner cavity of the bottom bin 1. This can not only effectively prevent the blockage of the bottom bin 1, but also eliminate the need to open the discharge port to pour the rice into the feed channel 2 again, thereby improving the working efficiency of the elevator.

[0035] In the work flow provided by the present invention, the rice is first evenly introduced into the bucket elevator through the feed channels 2 on both sides of the bottom bin 1. The design of the feed channel 2 ensures that the rice can smoothly enter the bottom bin 1, and prepare for the subsequent grabbing and transportation. The transmission motor 8 is started, and the motor drives the driving wheel 9 to start rotating. The driving wheel 9 is connected to the driven wheel 11 on the top rotating shaft 15 through the connecting belt 12, thereby driving the two transmission wheels 10 to rotate synchronously, and the transmission belt 13 on the transmission wheel 10 moves accordingly, driving the multiple hoppers 14 fixed between the transmission belts 13 to start circulating motion. When the hopper 14 swings downward, the grabbing teeth 142 inside it will penetrate into the rice pile, effectively grab the rice and bring it into the storage part 141. As the transmission belt 13 continues to move, the hopper 14 carries the rice and rises upward along the feeding channel 3 until it reaches the top bin 4. During this process, the hopper 14 always remains stable to ensure that the rice will not scatter or overflow. When the hopper 14 moves to the top bin 4, due to the change in direction of the transmission belt 13, the hopper 14 begins to flip, and the rice is poured out of the hopper 14 and flows out through the discharge channel 5 on one side of the top bin 4. The rice is transported to the subsequent production link through the discharge channel 5 to complete the entire lifting and transportation process. When it is necessary to adjust the tightness of the transmission component, the operator rotates the hexagonal nuts at one end of the two threaded rods 18. The threaded rods 18 are connected to the external threads of the bottom bin 1. Rotating the nuts will drive the threaded rods 18 to rotate and move along the outside of the bottom bin 1. Since the other end of the threaded rod 18 is rotatably connected to the outside of the moving plate 17, the moving plate 17 will slide with the movement of the threaded rod 18. The sliding of the moving plate 17 will drive the bearing 16 and the two ends of the rotating shaft 15 connected thereto to move, thereby changing the tightness of the transmission component. When the tightness of the transmission component reaches the preset appropriate range, the operator stops turning the nuts to complete the tightness adjustment.

[0036] The motor and its circuit are disclosed in the present invention as prior art, and thus will not be described in detail.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
