Description

Technical Field

[0001] The invention relates to the technical field of color sorters, in particular to a high-precision color sorting mechanism for eliminating material skipping and an application thereof in grain screening. Background Art

[0002] Through color sorting technology, impurities, diseased grains, immature grains and other bad grains can be removed from the grains, thereby improving the overall quality of the grains.

[0003] Specifically, color sorting technology detects the color differences of grains and uses photoelectric effects and image processing technology to automatically separate grains that do not meet the standards, ensuring that the remaining grains have better appearance and quality. When sorting grains, belt transmission devices and color sorters are required. The belt transmission device can transport the grains to the bottom of the color sorter, thereby achieving stable and efficient color sorting purposes.

[0004] In actual use, in order to improve the color sorting effect, grains can only be laid in one layer on the belt transmission device (if stacking occurs, the grains in the lower layer cannot be color sorted). At this time, the grain delivery amount needs to be controlled so that the grain delivery amount is equal to the actual amount of grain carried by the belt transmission device in a single layer. However, considering the diameter differences between individual grain particles, it is often difficult to accurately control the delivery amount, resulting in too much grain affecting the color sorting accuracy or too little grain affecting the color sorting speed.

[0030] An application of the high-precision color sorting mechanism for eliminating material skipping in grain screening.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] When the raw materials fall onto the belt transmission device through the discharge pipe, it is not necessary to accurately control the amount of the raw materials, but only to make the amount of the raw materials larger than the amount of a single layer of raw materials that the belt transmission device can bear, so that the excess raw materials can be spread flat under the action of the abutment plate, and the raw materials can be spread as a layer on the belt transmission device, thereby improving the color sorting accuracy. At the same time, the excess and redundant raw materials can move toward the end of the abutment plate under the guidance of the abutment plate, thereby reducing the accumulation of raw materials on the belt transmission device, preventing the relative sliding of the lower layer of raw materials and the belt transmission device due to the accumulation of raw materials, resulting in a situation where there is no raw material in a certain area of ​​the belt transmission device, and ensuring that the color sorter body can perform color sorting at a predetermined color sorting speed during color sorting;

[0033] By means of the elastic component, after the buffer plate is hit by the raw material, the first cylindrical spring can be used for buffering, so that the raw material can fall back onto the belt transmission device with less force, thereby reducing the number of repeated bounces of the raw material on the belt transmission device, avoiding the occurrence of the raw material continuing to collide with the belt transmission device after reverse ejection and ejecting multiple times, shortening the bouncing time of the raw material on the belt transmission device, and improving the stability of the raw material when being transported;

[0034] By means of the arranged driving assembly, driving part and guiding groove, the driving part can move along the length direction of the abutment plate to drive away the raw materials accumulated on the side of the abutment plate, thereby increasing the movement speed of the excessive and redundant raw materials along the length direction of the abutment plate, and avoiding the accumulation and stacking of excessive and redundant raw materials on the side of the abutment plate, so as to further avoid the accumulation of raw materials leading to relative sliding between the lower layer raw materials and the belt transmission device, resulting in a situation where there is no raw material in a certain area of ​​the belt transmission device, thereby improving the flattening effect of the raw materials on the belt transmission device, and when the driving part moves in the reverse direction, the driving part can be lifted to a certain height, thereby avoiding driving the raw materials to the middle part of the abutment plate during the resetting process of the driving part, causing the raw materials to accumulate.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0050] See also Figures 1 to 12 In an embodiment of the present invention, a high-precision color sorting mechanism for eliminating material jumping includes: a base 1, a feed tube 4, an elastic component, a stop plate 12, a two-way toggle mechanism and a return feed component.

[0051] A belt transmission device 11 and a color sorter body 2 are provided on the base 1. Two groups of side panels 3 connected to the base 1 are symmetrically provided on both sides of the belt transmission device 11. The side panels 3 are fitted with the sides of the belt transmission device 11 to prevent the raw materials from slipping off the sides of the belt transmission device 11.

[0052] When in use, the raw materials can enter the belt transmission device 11 through the feed tube 4. During this process, the lower end of the feed tube 4 should be kept at a certain distance from the belt transmission device 11 to make the raw materials fall more smoothly, and avoid the feed tube 4 being too close to the belt transmission device 11, which may cause the feed to be blocked, affect the feed speed, and cause the feed amount to be lower than the actual carrying capacity of the belt transmission device 11, thereby improving the carrying capacity of the belt transmission device 11 and the color sorting speed of the color sorter body 2.

[0053] Among them, the side plates 3 on both sides of the belt transmission device 11 can limit the raw materials falling onto the belt transmission device 11, so that when the raw materials fall onto the belt transmission device 11, they can only move along the length direction of the belt transmission device 11 to prevent the raw materials from slipping off and rolling out from the side of the belt transmission device 11.

[0054] The feed pipe 4 is disposed on the base 1, and the feed pipe 4 can guide the raw materials obliquely to the belt transmission device 11;

[0055] The elastic component is arranged on the belt transmission device 11, and the elastic component is used to suppress the jumping of the raw material on the belt transmission device 11;

[0056] The elastic component includes a bracket 5 fixedly connected to the side plate 3, the bracket 5 is fixedly connected to the feed pipe 4, and a parallel inclined plate 6 and a buffer plate 7 are arranged on the bracket 5, and the inclined plate 6 and the buffer plate 7 are connected through an energy storage structure;

[0057] When the raw material enters the belt transmission device 11 from the discharge pipe 4 and bounces, it can hit the buffer plate 7 and be buffered by the energy storage structure. Specifically, the energy storage structure includes a connecting shaft 8 fixedly connected to the buffer plate 7 and slidably connected to the inclined plate 6, a limiting ring 10 is provided at one end of the connecting shaft 8, and a first columnar spring 9 is sleeved on the connecting shaft 8, one end of the first columnar spring 9 is connected to the inclined plate 6, and the other end is connected to the limiting ring 10.

[0058] When the raw material enters the belt transmission device 11 from the feeding tube 4, there is a certain gap between the feeding tube 4 and the belt transmission device 11. At this time, the falling raw material will bounce when it contacts the belt transmission device 11. Specifically, the raw material guided by the feeding tube 4 and falling onto the belt transmission device 11 can produce reverse ejection and hit the buffer plate 7 after rebounding. In the initial state, the first column spring 9 is in a natural state, so that when the buffer plate 7 is hit by the raw material, the first column spring 9 can be used for buffering, so that the raw material can fall back to the belt transmission device 11 with less force, so as to reduce the number of repeated bounces of the raw material on the belt transmission device 11, avoid the raw material continuing to collide with the belt transmission device 11 after reverse ejection and eject multiple times, shorten the bouncing time of the raw material on the belt transmission device 11, and improve the stability of the raw material when being transported.

[0059] See also Figure 1 , Figure 7-Figure 8 The push plate 12 is arranged on the belt transmission device 11, and the push plate 12 is used to make the raw materials on the belt transmission device 11 flat. Specifically, the push plate 12 has a "V"-shaped structure, and the two sides of the push plate 12 are fixedly connected to the side plate 3. There are two guide grooves, which are symmetrically arranged on both sides of the push plate; further, there is a certain gap between the push plate 12 and the belt transmission device 11, and the gap is slightly larger than the diameter of the raw material.

[0060] Specifically, the V-shaped opening of the abutment plate 12 faces away from the discharge pipe 4, so that when the raw material is on the belt transmission device 11, it can abut against the abutment plate 12. When the belt transmission device 11 drives the raw material to move horizontally, the abutment plate 12 has a tendency to scrape the raw material to make the raw material evenly spread on the belt transmission device 11. Moreover, since the abutment plate 12 is in a "V"-shaped structure, when the raw material on the belt transmission device 11 touches the middle part of the abutment plate 12, it can be guided by both sides of the abutment plate 12 to make the excess raw material on the belt transmission device 11 roll along the length direction of the abutment plate 12, so that the excess raw material can finally move to the connection position between the abutment plate 12 and the side plate 3, and under the action of the return component, the excess part of the raw material is transported back to the discharge pipe 4, thereby avoiding the accumulation of raw materials on the belt transmission device 11 due to a large amount of raw materials, resulting in the problem of poor color sorting accuracy caused by the color sorter body 2 being able to color sort the raw materials on the upper layer.

[0061] In this embodiment, when the raw materials fall onto the belt transmission device 11 through the discharge pipe 4, it is not necessary to accurately control the amount of the raw materials, but only to make the amount of the raw materials greater than the amount of a single layer of raw materials that the belt transmission device 11 can bear, so that under the action of the abutment plate 12, the excess raw materials can be spread flat, and the raw materials can be laid as a layer on the belt transmission device 11, thereby improving the color sorting accuracy. At the same time, the excess and redundant raw materials can move toward the end of the abutment plate 12 under the guidance of the abutment plate 12, thereby reducing the accumulation of raw materials on the belt transmission device 11, preventing the lower layer of raw materials from sliding relative to the belt transmission device 11 due to the accumulation of raw materials, resulting in a situation where there is no raw material in a certain area of ​​the belt transmission device 11, and ensuring that the color sorter body 2 can perform color sorting at a predetermined color sorting speed during color sorting.

[0062] The two-way toggle mechanism is arranged on the abutment plate 12, and the two-way toggle mechanism includes a driving assembly, a driving portion 21 and a guide groove. The driving assembly cooperates with the guide groove to enable the driving portion 21 to drive the raw materials accumulated on the abutment plate 12 in one direction;

[0063] The driving assembly includes electric telescopic rods 13 symmetrically arranged on both sides of the abutment plate 12, and a transverse moving frame 14 is connected to the action end of the electric telescopic rod 13;

[0064] The driving assembly further comprises a telescopic structure adapted to the guide groove, one end of the telescopic structure is connected to a sliding connection member 17, and the sliding connection member 17 is slidably connected to a guide shaft 16 provided on the abutment plate 12;

[0065] The sliding connector 17 is connected to the transverse frame 14 via a mosaic structure, and the mosaic structure can drive the two groups of telescopic structures to move along the length direction of the support plate 12 when the transverse frame 14 moves. The mosaic structure includes a mosaic shaft 23 rotatably connected to the sliding connector 17 and a retardation groove 15 arranged along the length direction of the transverse frame 14, and the mosaic shaft 23 can roll in the retardation groove 15.

[0066] In the process of the belt transmission device 11 driving the raw materials to move, the electric telescopic rod 13 moves, and the electric telescopic rod 13 can drive the transverse frame 14 to perform a reciprocating motion relative to the abutment plate 12. In this process, since the sliding connection 17 slides along the guide shaft 16, and the embedded shaft 23 can roll along the retardation groove 15, when the transverse frame 14 moves toward the abutment plate 12, the retardation groove 15 cooperates with the embedded shaft 23 to drive the sliding connection 17 to move along the guide shaft 16, and in this process, the embedded shaft 23 will also move along the retardation groove 15. The driving portion 21 can move in the length direction of the abutment plate 12 to drive the raw materials accumulated on the side of the abutment plate 12, thereby increasing the movement speed of the excessive and redundant raw materials along the length direction of the abutment plate 12, and avoiding the accumulation of excessive and redundant raw materials on the side of the abutment plate 12, so as to further avoid the accumulation of raw materials leading to relative sliding between the lower layer of raw materials and the belt transmission device 11, resulting in a situation where there is no raw material in a certain area of ​​the belt transmission device 11, thereby improving the flattening effect of the raw materials on the belt transmission device 11.

[0067] When the transverse moving frame 14 moves away from the abutment plate 12, the two sets of driving parts 21 will move closer to each other along the length direction of the abutment plate 12. At this time, the telescopic structure cooperates with the guide groove to enable the driving parts 21 to be raised to a certain height, thereby avoiding driving the raw materials to the middle part of the abutment plate 12 during the resetting process of the driving parts 21, as follows:

[0068] See also Figure 3 , Figure 7 to Figure 10 The telescopic structure includes a vertical shaft 18 fixedly connected to the sliding connection member 17, a lifting member 20 is slidably mounted on the vertical shaft 18, and one end of the lifting member 20 away from the sliding connection member 17 is connected to the driving portion 21;

[0069] The vertical shaft 18 is also sleeved with a second cylindrical spring 19, one end of the second cylindrical spring 19 is connected to the sliding connection member 17, and the other end is connected to the lifting member 20;

[0070] The convex shaft 22 fixedly connected to the lifting member 20 can slide in the guide groove, and the guide groove includes two groups of first horizontal grooves 24 and inclined grooves 26 symmetrically arranged on the abutment plate 12, the first horizontal grooves 24 are connected to the inclined grooves 26, and the ends of the two groups of the first horizontal grooves 24 away from the inclined grooves 26 are connected through the vertical grooves 25, the ends of the two groups of the inclined grooves 26 away from the first horizontal grooves 24 overlap, and the ends of the two groups of the inclined grooves 26 are connected to the second horizontal grooves 27;

[0071] Deflecting members 28 are rotatably mounted at the ends of the two groups of inclined slots 26 , and the deflecting members 28 abut against the lower side of the second horizontal slot 27 .

[0072] The two groups of first horizontal grooves 24 mentioned above are distributed vertically up and down.

[0073] In the initial state, the driving portion 21 is flush with the lower end of the plate 12. At this time, the second column spring 19 is in a compressed state, and the convex shaft 22 is at one end of the first horizontal groove 24 at the bottom facing the vertical groove 25, so that when the sliding connection 17 moves along the length direction of the guide shaft 16, it can drive the driving portion 21 to move along the length direction of the plate 12, thereby actively driving the excess raw material on the side of the plate 12 to move, and accelerating the movement speed of the raw material along the length direction of the plate 12. To avoid the accumulation of raw materials, when the driving part 21 moves to the end of the stroke, 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 to the first horizontal groove 24. At this time, the convex shaft 22 drives the lifting member 20 to move toward 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 will abut against the deflection member 28. At this time, the deflection member 28 can deflect upward, and when the convex shaft 22 moves to the second horizontal groove 27 and separated from the deflection member 28, the deflection member 28 can be reset under the action of gravity, so that when the sliding connection member 17 moves in the reverse direction, when the convex shaft 22 abuts against the deflection member 28 again, the deflection member 28 abuts against the lower side wall of the second horizontal groove 27, so that the convex shaft 22 can enter the upper inclined groove 26 under the guidance of the deflection member 28, so that the driving part 21 further rises, and then the convex shaft 22 moves along the upper first horizontal groove 24 until the convex shaft 22 moves to the upper After reaching the end of the first horizontal groove 24, the second columnar spring 19 releases its elastic potential energy to drive the lifting member 20 to move downward, and resets the convex shaft 22 to its initial state, so that during the reciprocating motion of the driving portion 21, when it moves toward the middle position of the abutment plate 12, the driving portion 21 can be lifted to a certain height to separate from the raw materials on the side of the abutment plate 12, and prevent the raw materials on the side of the abutment plate 12 from being driven to the middle of the abutment plate 12 to cause accumulation of the raw materials during the resetting of the driving portion 21.

[0074] It should be noted that the two sets of inclined grooves 26 can lift the driving portion 21 and prevent the driving portion 21 from driving the raw material at the end of the abutment plate 12 in the reverse direction when the convex shaft 22 moves in the second horizontal groove 27 .

[0075] See also Figure 1-2 , Figure 11-12 The return conveying assembly is connected to the belt transmission device 11, and the return conveying assembly can convey excess raw materials back to the discharge pipe 4. The return conveying assembly includes an outer shell 30 installed on the base 1, and the lower end of the outer shell 30 is provided with a discharge channel 29 connected to the side plate 3, and the upper end is provided with a return conveying channel 33 connected to the discharge pipe 4;

[0076] The return assembly further includes a drive motor 32 fixedly mounted on the outer shell 30 , and an output shaft of the drive motor 32 is fixedly connected to a spiral twisting roller 31 rotatably mounted in the outer shell 30 .

[0077] When the excess and redundant raw materials are driven to the end of the abutment plate 12, this part of the raw materials can pass through the side plate 3 and enter the discharge channel 29. During this process, the raw materials can slide into the outer shell 30 under the action of gravity, and under the action of the spiral twister 31, this part of the raw materials is lifted. After the raw materials are lifted to a certain height, the raw materials can return to the discharge pipe 4 through the return channel 33, so that the excess raw materials can fall from the discharge pipe 4 to the belt transmission device 11 again, and perform a secondary flat color sorting action to ensure the integrity of the raw material color sorting.
