Description

TECHNICAL FIELD

[0001] The application relates to the technical field of color sorting machines, and particularly relates to a high-precision color sorting mechanism capable of eliminating material jumping and application of the high-precision color sorting mechanism in grain screening. BACKGROUND

[0002] By means of the color sorting technology, impurities, diseased spot grains, unripe grains and other undesirable grains in the grains can be removed, so that the overall quality of the grains is improved.

[0003] Specifically, the color sorting technology can automatically separate the grains that do not meet the standards by detecting the color difference of the grains, utilizing the photoelectric effect and the image processing technology, and ensuring that the remaining grains have better appearance and quality. When the grains are color sorted, a belt conveying device and a color sorting machine need to be used. The belt conveying device can convey the grains to the lower part of the color sorting machine, so that the color sorting is stable and efficient.

[0004] However, in actual use, in order to improve the color sorting effect, the grains can only be laid in one layer on the belt conveying device (if the grains are stacked, the lower grains cannot be color sorted), and at this time, the conveying amount of the grains needs to be controlled, so that the conveying amount of the grains is equal to the actual amount of the belt conveying device carrying the single-layer grains. However, considering the diameter difference between the individual grains, the control of the conveying amount is often difficult to be accurate, so that the color sorting precision is affected due to too much amount of the grains or the color sorting speed is affected due to too little amount of the grains.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] In addition, elements in the present application can be referred to as being "fixed" or "disposed" on another element. It can be directly on another element or there can be intervening elements. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can be present. As used herein the terms "vertical", "horizontal", "left", "right" and the like are merely used for the purpose of illustration and are not intended to be limiting.

[0050] Referring to Figures 1-12 In the embodiment of the present application, a high-precision color selection mechanism for eliminating material jumping includes a base 1, a feeding pipe 4, an elastic assembly, a stop plate 12, a bidirectional shifting mechanism and a return assembly.

[0051] The base 1 is provided with a belt conveying device 11 and a color selection machine body 2. Two groups of side plates 3 connected with the base 1 are symmetrically arranged on both sides of the belt conveying device 11. The side plates 3 are attached to the side of the belt conveying device 11, which can prevent the raw materials from slipping off the side of the belt conveying device 11.

[0052] In use, the raw materials can enter the belt conveying device 11 through the feeding pipe 4. In this process, the lower end of the feeding pipe 4 should be at a certain distance from the belt conveying device 11 to make the falling of the raw materials more smooth, avoid the feeding pipe 4 being too close to the belt conveying device 11, causing the feeding plug to be blocked, affecting the feeding speed and causing the feeding amount to be lower than the actual carrying capacity of the belt conveying device 11, and improving the carrying capacity of the belt conveying device 11 and the color selection speed of the color selection machine body 2.

[0053] Among them, the side plates 3 on both sides of the belt conveying device 11 can limit the raw materials falling on the belt conveying device 11, so that the raw materials falling on the belt conveying device 11 can only move along the length direction of the belt conveying device 11, to prevent the raw materials from slipping out of the side of the belt conveying device 11.

[0054] The feeding pipe 4 is arranged on the base 1. The feeding pipe 4 can guide the raw materials to the belt conveying device 11 in an inclined manner.

[0055] The elastic assembly is arranged on the belt conveying device 11. The elastic assembly is used to suppress the jumping of the raw materials on the belt conveying device 11.

[0056] The elastic assembly includes a bracket 5 fixedly connected with the side plate 3. The bracket 5 is fixedly connected with the feeding pipe 4. Parallel inclined plates 6 and buffer plates 7 are arranged on the bracket 5. The inclined plates 6 and the buffer plates 7 are connected through an energy storage structure.

[0057] When the raw materials enter the belt conveying device 11 from the discharging pipe 4, they can hit the buffer plate 7 and be buffered by the energy storage structure. Specifically, the energy storage structure comprises a connecting shaft 8 fixedly connected with the buffer plate 7 and slidably connected with the inclined plate 6. One end of the connecting shaft 8 is provided with a limiting ring 10, and a first cylindrical spring 9 is sleeved on the connecting shaft 8. One end of the first cylindrical spring 9 is connected with the inclined plate 6, and the other end is connected with the limiting ring 10.

[0058] When the raw materials enter the belt conveying device 11 from the discharging pipe 4, they can hit the buffer plate 7 and be buffered by the energy storage structure. Specifically, the energy storage structure comprises a connecting shaft 8 fixedly connected with the buffer plate 7 and slidably connected with the inclined plate 6. One end of the connecting shaft 8 is provided with a limiting ring 10, and a first cylindrical spring 9 is sleeved on the connecting shaft 8. One end of the first cylindrical spring 9 is connected with the inclined plate 6, and the other end is connected with the limiting ring 10.

[0059] Please refer to Figure 1 、 Figures 7-8 , the abutting plate 12 is arranged on the belt conveying device 11, and the abutting plate 12 is used for flattening the raw materials on the belt conveying device 11. Specifically, the abutting plate 12 is in a "V" shape structure, and the two sides of the abutting plate 12 are fixedly connected with the side plate 3. The guide groove is provided with two, which are symmetrically arranged on both sides of the abutting plate. Further, the abutting plate 12 and the belt conveying device 11 have a certain gap, which is slightly larger than the diameter of the raw materials.

[0060] Specifically, the V-shaped opening of the abutting plate 12 is away from the feeding pipe 4, so that when the raw materials are on the belt conveying device 11, the abutting plate 12 can abut against the raw materials. When the belt conveying device 11 drives the raw materials to move horizontally, the abutting plate 12 has a tendency to scrape the raw materials to move, so that the raw materials can be evenly spread on the belt conveying device 11. Because the abutting plate 12 has a V-shaped structure, when the raw materials on the belt conveying device 11 reach the middle part of the abutting plate 12, the excess raw materials on the belt conveying device 11 can roll along the length direction of the abutting plate 12 under the guidance of the two sides of the abutting plate 12, so that the excess raw materials can finally move to the position where the abutting plate 12 is connected with the side plate 3, and under the action of the returning assembly, the excess raw materials can be re-fed back to the feeding pipe 4, thereby avoiding the problem that the color selection accuracy is poor because the raw materials are piled up on the belt conveying device 11, and the color selection machine body 2 can only select the upper layer of raw materials.

[0061] In this embodiment, when the raw materials fall from the feeding pipe 4 to the belt conveying device 11, the amount of the raw materials does not need to be accurately controlled, but only needs to be greater than the amount of the single layer of raw materials that the belt conveying device 11 can bear, so that under the action of the abutting plate 12, the excess raw materials can be spread, and the raw materials can be laid on the belt conveying device 11 as a single layer, thereby improving the color selection accuracy. Meanwhile, the excess raw materials can move towards the end of the abutting plate 12 under the guidance of the abutting plate 12, thereby reducing the phenomenon that the raw materials are piled up on the belt conveying device 11, preventing the lower layer of raw materials from sliding relative to the belt conveying device 11 due to the piling up of the raw materials, and preventing the situation that there is no raw materials in a certain area of the belt conveying device 11, thereby ensuring that the color selection machine body 2 can select at a predetermined color selection speed.

[0062] The bidirectional pushing mechanism is arranged on the abutting plate 12, and the bidirectional pushing mechanism comprises a driving assembly, a pushing part 21 and a guide groove. The driving assembly cooperates with the guide groove to enable the pushing part 21 to push the raw materials piled on the abutting plate 12 in one direction.

[0063] The driving assembly comprises electric telescopic rods 13 symmetrically arranged on the two sides of the abutting plate 12, and a horizontal moving frame 14 is connected to the action end of each electric telescopic rod 13.

[0064] The driving assembly further comprises a telescopic structure matched with the guide groove, one end of the telescopic structure is connected with a sliding connecting piece 17, and the sliding connecting piece 17 is slidingly connected with a guide shaft 16 arranged on the abutting plate 12.

[0065] The sliding connector 17 is connected with the horizontal moving frame 14 through an embedding structure, which can drive the two groups of telescopic structures to move along the length direction of the resisting plate 12 when the horizontal moving frame 14 is in action, the embedding structure comprises an embedding shaft 23 which is rotationally connected with the sliding connector 17 and a containing groove 15 which is arranged along the length direction of the horizontal moving frame 14, the embedding shaft 23 can roll in the containing groove 15.

[0066] In the process of moving the raw materials by the belt conveying device 11, the electric telescopic rod 13 is in action, at this time, the electric telescopic rod 13 can drive the horizontal moving frame 14 to perform reciprocating action relative to the resisting plate 12, in which, since the sliding connector 17 slides along the guide shaft 16 and the embedding shaft 23 can roll along the containing groove 15, when the horizontal moving frame 14 moves towards the resisting plate 12, the containing groove 15 can drive the sliding connector 17 to move along the guide shaft 16 by cooperating with the embedding shaft 23, and in this process, the embedding shaft 23 will also move along the length direction of the containing groove 15, so that the driving part 21 can move along the length direction of the resisting plate 12, so as to drive the raw materials accumulated on the side of the resisting plate 12, thereby improving the movement speed of the excessive and redundant raw materials along the length direction of the resisting plate 12, avoiding the accumulation of a large amount of raw materials on the side of the resisting plate 12, and further avoiding the accumulation of raw materials to cause the relative sliding between the lower raw materials and the belt conveying device 11, so as to avoid the situation that there is no raw material in a certain area of the belt conveying device 11, and improve the paving effect of the raw materials on the belt conveying device 11.

[0067] When the horizontal moving frame 14 moves away from the resisting plate 12, the two groups of driving parts 21 will move towards each other along the length direction of the resisting plate 12, at this time, the telescopic structure cooperates with the guide groove, so that the driving part 21 can be lifted to a certain height, thereby avoiding driving the raw materials to the middle of the resisting plate 12 in the process of resetting the driving part 21, and the specific process is as follows:

[0068] Please refer to Figure 3 、 Figures 7-10 , the telescopic structure comprises a vertical shaft 18 which is fixedly connected with the sliding connector 17, the vertical shaft 18 is slidably connected with a lifting piece 20, and one end of the lifting piece 20 away from the sliding connector 17 is connected with the driving part 21;

[0069] The vertical shaft 18 is further sleeved with a second columnar spring 19, one end of the second columnar spring 19 is connected with the sliding connector 17, and the other end is connected with the lifting piece 20;

[0070] The convex shaft 22 fixedly connected with the lifting member 20 is capable of sliding in the guide groove, which comprises two groups of first horizontal grooves 24 and inclined grooves 26 symmetrically arranged on the resisting plate 12, the first horizontal grooves 24 and the inclined grooves 26 are communicated, the ends of the two groups of first horizontal grooves 24 away from the inclined grooves 26 are connected by a vertical groove 25, the ends of the two groups of inclined grooves 26 away from the first horizontal grooves 24 are coincident, and the ends of the two groups of inclined grooves 26 are connected with a second horizontal groove 27;

[0071] The ends of the two groups of inclined grooves 26 are rotatably installed with deflection members 28, which abut against the lower side of the second horizontal groove 27.

[0072] The two groups of first horizontal grooves 24 are distributed vertically.

[0073] In the initial state, the driving part 21 is flush with the lower end of the resisting plate 12, at this time the second cylindrical spring 19 is in a compressed state, and the convex shaft 22 is at one end of the lower first horizontal groove 24 facing the vertical groove 25, so that when the sliding connecting member 17 moves along the length direction of the guide shaft 16, the driving part 21 can be driven to move along the length direction of the resisting plate 12, thereby actively driving the excess raw materials on the side of the resisting plate 12 to move, and accelerating the movement speed of the raw materials along the length direction of the resisting plate 12, avoiding the accumulation of raw materials. When the driving part 21 moves to the stroke end, the convex shaft 22 will move to the end of the first horizontal groove 24, and then the convex shaft 22 will move along the inclined groove 26 connected with the first horizontal groove 24, at this time the convex shaft 22 drives the lifting member 20 to move towards the vertical shaft 18, so that the driving part 21 is lifted. After the convex shaft 22 moves to the end of the inclined groove 26, it abuts against the deflection member 28, at this time the deflection member 28 can be deflected upward, and when the convex shaft 22 moves into the second horizontal groove 27 and separates from the deflection member 28, the deflection member 28 can be reset under the action of gravity. When the convex shaft 22 abuts against the deflection member 28 again during the reverse movement of the sliding connecting member 17, the convex shaft 22 can enter the upper inclined groove 26 under the guidance of the deflection member 28 due to the abutment between the deflection member 28 and the lower side wall of the second horizontal groove 27, thereby further lifting the driving part 21. Then the convex shaft 22 moves along the upper first horizontal groove 24, and after the convex shaft 22 moves to the end of the upper first horizontal groove 24, the second cylindrical spring 19 releases the elastic potential energy to drive the lifting member 20 to move downward, and the convex shaft 22 is reset to the initial state, thereby realizing that when the driving part 21 moves towards the middle position of the resisting plate 12 during the reciprocating movement of the driving part 21, the driving part 21 can be lifted to a certain height to separate from the raw materials on the side of the resisting plate 12, thereby preventing the raw materials on the side of the resisting plate 12 from being driven to the middle of the resisting plate 12 during the resetting process of the driving part 21, causing the accumulation of raw materials.

[0074] It should be noted that the two groups of inclined grooves 26 can lift the driving part 21 and prevent the driving part 21 from driving the raw materials at the end of the resisting plate 12 in the opposite direction when the convex shaft 22 moves in the second horizontal groove 27.

[0075] Please refer to Figures 1-2 、 Figures 11-12 The return assembly is connected with the belt conveying device 11 and can convey the excess raw materials back into the discharging pipe 4, and the return assembly comprises an outer housing 30 mounted on the base 1, the lower end of the outer housing 30 is provided with a discharging channel 29 connected with the side plate 3, and the upper end is provided with a return channel 33 connected with the discharging pipe 4.

[0076] The return assembly further comprises a driving motor 32 fixedly mounted on the outer housing 30, and the output shaft of the driving motor 32 is fixedly connected with a spiral auger 31 rotatably mounted in the outer housing 30.

[0077] When the excess and redundant raw materials are driven to the end of the resisting plate 12, the raw materials can pass through the side plate 3 and enter the discharging channel 29, in this process, the raw materials can slide into the outer housing 30 under the action of gravity, and under the action of the spiral auger 31, the raw materials are lifted, and when the raw materials are lifted to a certain height, the raw materials can return to the discharging pipe 4 through the return channel 33, so that the excess raw materials can fall again from the discharging pipe 4 to the belt conveying device 11 and perform a secondary flat-paving color selection action, ensuring the integrity of the color selection of the raw materials.

[0078] As an embodiment of the present application, the application of the high-precision color selection mechanism for eliminating the jumping raw materials in the screening of grains is also proposed, wherein in the present application, the types of grains are mainly beans (red beans, soybeans, mung beans, etc.).
