Description

Technical Field

[0001] This utility model relates to the field of rice production technology, and in particular to a feeding device for rice processing. Background Technology

[0002] Rice is a finished product made from paddy through processes such as cleaning, hulling, milling, and finishing. The rice processing process requires processing equipment such as cleaning sieves, hulling machines, and polishing machines, and all of these processing equipment require feeding hoppers to transport rice into the processing equipment.

[0003] The existing feed hopper has a problem with uneven feeding because it cannot control the speed at which the rice falls. As a result, the rice accumulates at the bottom of the feed hopper and blocks it, slowing down the speed at which the rice enters the processing equipment and affecting the efficiency of the processing equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feeding device for rice processing, which solves the problem of uneven feeding in the feeding hopper in existing technologies.

[0005] According to an embodiment of this utility model, a feeding device for rice processing includes a main body and a guide pipe disposed at the bottom of the main body, and a mounting plate disposed at the bottom of the guide pipe. The mounting plate is provided with a rotatable main shaft that extends into the guide pipe. A feeding plate is provided on the portion of the main shaft located inside the guide pipe. A rotatable adapter is also provided on the main shaft. The rotation axis of the adapter is consistent with the radial direction of the main shaft. The mounting plate is also provided with a rotatable transmission component and a drive motor that is connected to the transmission component. The transmission component is provided with a first connecting rod and a first mounting hole. The angle between the axial direction of the first connecting rod and the axial direction of the first mounting hole is an acute angle. The first connecting rod cooperates with the output end of the drive motor. The adapter is provided with a second connecting rod that cooperates with the first mounting hole.

[0006] Furthermore, the feed tube is provided with a through hole and the axial direction of the through hole is consistent with the radial direction of the feed tube. The mounting plate is provided with a first mounting seat and the first mounting seat has a second mounting hole aligned with the through hole. The two ends of the spindle are respectively engaged with the through hole and the second mounting hole.

[0007] Furthermore, the main shaft is provided with a first sleeve, which is located inside the guide tube and has a plurality of material feeding plates spaced apart along the circumference of the main shaft.

[0008] Furthermore, the material feeding plate is provided with material leakage holes at intervals, and the material leakage holes respectively penetrate the material feeding plate.

[0009] Furthermore, the main shaft is provided with a second sleeve, the second sleeve is provided with a connecting pin and the axial direction of the connecting pin is consistent with the radial direction of the main shaft, and the adapter is provided with a third mounting hole that cooperates with the connecting pin.

[0010] Furthermore, the mounting plate is also provided with a second mounting base, which has a fourth mounting hole for the first connecting rod to pass through, and the drive motor is fixedly connected to the second mounting base.

[0011] Furthermore, the top of the main body is provided with a mounting frame, on which a liftable conical block and a drive assembly connected to the conical block are provided. The conical block is located inside the main body and the drive assembly drives the conical block to extend into or out of the guide tube.

[0012] Furthermore, the drive assembly includes a cylinder and a piston rod disposed at the output end of the cylinder, the cylinder being fixed on the mounting bracket and the end of the piston rod away from the cylinder being fixedly connected to the conical block.

[0013] Furthermore, the end of the conical block away from the feed tube has a guide surface, and the height of the guide surface gradually decreases along the direction away from the axis of the conical block.

[0014] Furthermore, the mounting plate is provided with a plurality of through holes spaced apart, and the through holes respectively penetrate the mounting plate.

[0015] Compared with the prior art, this utility model has the following beneficial effects: by using a drive motor to drive the transmission component to rotate, the transmission component drives the adapter component to move and drive the main shaft to reciprocate. When the main shaft reciprocates, the feeding plate set on the main shaft swings back and forth in the guide tube. The movement of the feeding plate disperses the rice accumulated in the guide tube, allowing the rice to fall quickly along the guide tube, thereby preventing the guide tube from being blocked. This solves the technical problem of the existing feeding hopper not being smooth, and produces the technical effect of preventing the guide tube from being blocked during the feeding process and ensuring that the rice is stably input into the processing equipment.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a feeding device for rice processing, which is installed at the feeding end of rice processing equipment such as cleaning screens, rice hullers, polishing machines, etc., for feeding rice to be processed into the processing equipment.

[0022] like Figure 1 and Figure 2 As shown, the rice processing feeding device includes a main body 1 and a guide pipe 2 disposed at the bottom of the main body 1. The guide pipe 2 is connected to the feeding end of the processing equipment. After the rice to be processed is poured into the main body 1, it enters the guide pipe 2 under its own gravity and is fed into the processing equipment along the guide pipe 2. The rice processing feeding device also includes a mounting plate 3 disposed at the bottom of the guide pipe 2. The mounting plate 3 is provided with a rotatable main shaft 4, and the main shaft 4 extends into the guide pipe 2. The portion of the main shaft 4 located inside the guide pipe 2 is provided with a feeding plate 41. The main shaft 4 is also provided with a rotatable adapter 5. The rotation axis of the adapter 5 is consistent with the radial direction of the main shaft 4. The mounting plate 3 is also provided with a rotatable... The transmission component 6 and the drive motor 7 are connected to the transmission component 6. The transmission component 6 is provided with a first connecting rod 61 and a first mounting hole 62. The angle between the axial direction of the first connecting rod 61 and the axial direction of the first mounting hole 62 is an acute angle. The first connecting rod 61 cooperates with the output end of the drive motor 7. The adapter 5 is provided with a second connecting rod 51 that cooperates with the first mounting hole 62. When the transmission component 6 rotates under the drive of the drive motor 7, it drives the adapter 5 to move and drives the main shaft 4 to reciprocate around its axial direction. This causes the feeding plate 41 to swing back and forth under the drive of the main shaft 4, breaking up the rice accumulated in the guide tube 2, so that the rice can fall smoothly in the guide tube 2.

[0023] Specifically, the operation steps for feeding rice into the rice processing equipment using the rice processing feeding device provided in this embodiment are as follows: The rice processing feeding device is installed on the rice processing equipment so that the guide pipe 2 is connected to the feed end of the rice processing equipment. The rice to be processed is poured into the main body 1, allowing the rice to enter the guide pipe 2 under its own gravity and then enter the rice processing equipment along the guide pipe 2. When a blockage occurs in the guide pipe 2, the drive motor 7 is activated. The drive motor 7 drives the transmission component 6 to rotate, causing the... The transmission component 6 drives the adapter 5 to move and drives the main shaft 4 to reciprocate. When the main shaft 4 reciprocates, the material-dispensing plate 41 mounted on the main shaft 4 swings back and forth within the guide tube 2. The movement of the material-dispensing plate 41 disperses the rice accumulated in the guide tube 2, clearing the guide tube 2 and allowing the rice to fall quickly into the processing equipment along the guide tube 2, thereby preventing blockage of the guide tube 2. Alternatively, the drive motor 7 can be kept on during the feeding process of the rice processing feeding device to keep the guide plate unobstructed. The rice processing feeding device provided in this embodiment can prevent the guide tube 2 from becoming blocked during the feeding process, thus ensuring that the rice is smoothly input into the processing equipment.

[0024] like Figure 1 and Figure 2 As shown, the feed tube 2 has a through hole, and the axial direction of the through hole is consistent with the radial direction of the feed tube 2. The mounting plate 3 has a first mounting seat 31, and the first mounting seat 31 has a second mounting hole aligned with the through hole. The two ends of the main shaft 4 are respectively engaged with the through hole and the second mounting hole. The through hole on the feed tube 2 allows the main shaft 4 to pass through, and the first mounting seat 31 on the mounting plate 3 allows the main shaft 4 to be mounted. By passing the main shaft 4 through the second mounting hole and the through hole in sequence, the main shaft 4 can be mounted on the mounting plate 3, and part of the main shaft 4 can be extended into the feed tube 2. This keeps the position of the main shaft 4 on the mounting plate 3 stable, which helps to improve the structural stability of the feeding device for rice processing.

[0025] Please combine Figure 2 and Figure 3 The main shaft 4 is provided with a first sleeve 42, which is located inside the guide tube 2. Three material-dispensing plates 41 are spaced apart on the first sleeve 42 along the circumference of the main shaft 4. The first sleeve 42, sleeved on the guide tube 2, is used to connect the material-dispensing plates 41. The three material-dispensing plates 41 on the first sleeve 42 cause the main shaft 4 to rotate, and when the main shaft rotates, the three material-dispensing plates 41 simultaneously reciprocate, further improving the effect of breaking up accumulated rice during the reciprocating rotation of the main shaft 4.

[0026] In detail, the feeding plate 41 is provided with leakage holes 43 at intervals, and the leakage holes 43 pass through the feeding plate 41. The leakage holes 43 on the feeding plate 41 are used to allow rice to pass through the feeding plate 41, so as to prevent the feeding plate 41 from blocking the movement of rice in the guide tube 2 and causing material accumulation.

[0027] like Figure 3 As shown, the main shaft 4 is provided with a second sleeve 44, and the second sleeve 44 is provided with a connecting pin 45, the axial direction of the connecting pin 45 being consistent with the radial direction of the main shaft 4. The adapter 5 is provided with a third mounting hole 52 that mates with the connecting pin 45. By providing the second sleeve 44 on the main shaft 4 and providing the connecting pin 45 on the second sleeve 44 to mate with the third mounting hole 52 on the adapter 5, the rotational connection between the main shaft 4 and the adapter 5 can be achieved, and the adapter 5 can be ensured to rotate radially around the main shaft 4 when it operates.

[0028] Please refer to Figure 1 The mounting plate 3 is further provided with a second mounting base 32. The second mounting base 32 has a fourth mounting hole through which the first connecting rod 61 passes, and the drive motor 7 is fixedly connected to the second mounting base 32. The drive motor 7 is mounted to the mounting plate 3 by being fixedly connected to the second mounting base 32, and the second mounting base 32 has the fourth mounting hole that cooperates with the first connecting rod 61. After the first connecting rod 61 passes through the fourth mounting hole, it is connected to the output end of the drive motor 7, so that the position of the transmission component 6 on the mounting plate 3 remains stable and can rotate smoothly under the drive of the drive motor 7.

[0029] Please combine Figure 1 and Figure 2 The main body 1 has a mounting frame 11 on its top. The mounting frame 11 has a liftable conical block 12 and a drive assembly connected to the conical block 12. The conical block 12 is located inside the main body 1, and the drive assembly drives the conical block 12 to extend into or retract from the feed pipe 2. The drive assembly on the mounting frame 11 drives the conical block 12 to move vertically up and down, adjusting its position within the main body 1. As the conical block 12 moves up and down, the distance between it and the inner wall of the main body 1 changes accordingly. A larger distance between the conical block 12 and the inner wall of the main body 1 results in a larger flow rate of rice entering the feed pipe 2 from the main body 1. In other words, adjusting the position of the conical block 12 by the drive assembly controls the flow rate of rice entering the feed pipe, allowing for adjustment of the feeding speed according to the operating status of the processing equipment.

[0030] In this embodiment, the driving assembly includes a cylinder 13 and a piston rod 14 disposed at the output end of the cylinder 13. The cylinder 13 is fixed to the mounting bracket 11, and the end of the piston rod 14 away from the cylinder 13 is fixedly connected to the conical block 12. The piston rod 14 is extended or retracted into the cylinder 13 by the cylinder 13, causing the conical block 12 to move vertically under the action of the piston rod 14, thereby facilitating the adjustment of the position of the conical block 12.

[0031] like Figure 2 As shown, the conical block 12 has a guide surface 15 at the end away from the feed tube 2, and the height of the guide surface 15 gradually decreases along the direction away from the axis of the conical block 12. The guide surface 15, located at the top of the conical block 12, guides the rice falling on the top of the conical block 12 to slide towards the edge of the conical block 12 and fall off the conical block 12, thus avoiding material loss caused by rice remaining on the conical block 12 during the feeding process.

[0032] like Figure 1 As shown, the mounting plate 3 has multiple through holes 33 spaced apart, each of which penetrates the mounting plate 3. The rice processing feeding device can be fixed to the processing equipment by passing bolts through the through holes 33 and holes on the processing equipment, and then tightening them with nuts. This ensures a reliable connection between the rice processing feeding device and the processing equipment, and keeps the feed guide pipe 2 connected to the feed end of the processing equipment during the feeding process, thereby improving the reliability of the rice processing feeding device.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
