[0002] Color sorters are generally used to sort materials based on the differences in their optical properties or shape characteristics. They are widely used in the fields of food, agricultural and sideline products, and renewable resources. In the prior art, the discharge hopper of a color sorter is divided into a discharge cavity for qualified materials and a discharge cavity for unqualified materials, and the two cavities are separated by a middle partition. In the actual material sorting process, some curved materials with handles are easy to hang on the upper plate edge of the middle partition of the discharge hopper, especially when sorting materials that are easy to bend or have handles, such as peppers with handles, Chinese medicinal materials, and edamame clips. As the amount of materials piled up and hung on the middle partition increases, the separation function of the middle partition between qualified and unqualified materials is gradually weakened, which seriously affects the sorting effect of the materials and requires manual cleaning. This not only increases the labor intensity, but also requires the machine to be shut down for cleaning, affecting production and is very inconvenient. Utility Model Content

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] Please combine Figure 1 - Figure 5 A color sorter hopper cleaning device of this embodiment includes a rotating shaft 1, a motor 2 is arranged at one end of the rotating shaft 1, an elastic coupling 3 is connected between the rotating shaft 1 and the motor 2, and the motor 2 drives the rotating shaft 1 to rotate through the elastic coupling 3.

[0028] At the same time, mounting brackets 4 are connected to both ends of the rotating shaft 1, and the rotating shaft 1 can be conveniently installed in the hopper of the color sorter through the mounting brackets 4. In this embodiment, two mounting brackets 4 are provided, and the one far away from the motor 2 is defined as the No. 1 bracket 41, and the one close to the motor 2 is the No. 2 bracket 42. The No. 1 bracket 41 is internally installed with a bearing 5, which is rotatably connected to the rotating shaft 1 through the bearing 5, and the No. 2 bracket 42 is rotatably installed on the elastic coupling 3 through the bearing 5. At the same time, a screw hole is opened at the lower end of the No. 2 bracket 42, so that the rotating shaft 1 can be fixed in the hopper as a whole through screws.

[0029] In addition, a fixer 6 is installed on the rotating shaft 1. Similarly, there are two fixers 6, both of which are fixedly connected to the rotating shaft 1 and located on the inner sides of the two brackets. The one close to the No. 1 bracket 41 is defined as the No. 1 fixer 61, and the one close to the No. 2 bracket 42 is defined as the No. 2 fixer 62.

[0030] In addition, the present embodiment is also provided with a steel wire rope 8 for cleaning, the two ends of the steel wire rope 8 are respectively connected to the two fixing devices 6. In the present embodiment, a steel wire rope 8 with a diameter of 1.5 mm is preferably selected. A stopper 9 is fixedly connected to one end of the steel wire rope 8.

[0031] In order to fix the steel wire rope 8, a stepped mounting hole 611 is provided at the upper end of the first fixing device 61, a polyurethane elastic body 612 is installed in the mounting hole 611, a small hole is provided in the middle of the polyurethane elastic body 612, wherein the steel wire rope 8 can pass through the small hole, but the stopper 9 cannot pass through the small hole. In addition, an internal thread is provided on the inner wall of the end of the mounting hole 611, and a plug 613 is connected through the internal thread.

[0032] When in use, the steel wire rope 8 passes through the polyurethane elastic body 612 and extends out of the mounting hole 611, and is always connected to the second fixture 62, but the stopper 9 is blocked and stays in the mounting hole 611. Then the plug 613 is rotated to block the mounting hole 611.

[0033] Correspondingly, a lifting hole 621 is provided on the second fixer 62, and a collision assembly 7 is provided between the second fixer 62 and the second bracket 42. Specifically, a connecting block 71 is movably installed in the lifting hole 621, and a through connecting hole 72 is provided in the middle of the connecting block 71. The other end of the steel wire rope 8 passes through the connecting hole 72 and is then tied and fixed.

[0034] A spring rod 74 is provided inside the lifting hole 621, and holes are provided on both sides of the connecting block 71. The connecting block 71 is sleeved on the spring rod 74 and can move along the spring rod 74. That is, the lower half of the movable block is located in the lifting hole 621, and the upper half extends out of the lifting hole 621, and is provided with an arc-shaped collision surface 73. Therefore, the connecting block 71 can move along the spring rod 74, and the connecting block 71 is connected to the wire rope 8 at the same time. In order to avoid the problem that the connecting block 71 enters the lifting hole 621 and the second fixer 62 contacts the wire rope 8, a notch 622 is provided at the side of the second fixer 62 (the wall of the lifting hole 621). When the connecting block 71 moves, the wire rope 8 is prevented from contacting the second fixer 62.

[0035] In addition, the collision assembly 7 further comprises a blocking rod 75, wherein the blocking rod 75 is fixedly connected to the second bracket 42, and the front end of the blocking rod 75 is hemispherical.

[0036] The implementation process and principle of a color sorter hopper cleaning device in the embodiment of the present application are as follows:

[0037] (I): Install the steel wire rope 8, and make the steel wire rope 8 pass through the mounting hole 611 on the No. 1 fixture 61 and the connecting hole 72 on the connecting block 71 in sequence. At the same time, after the steel wire rope 8 passes through the polyurethane elastic body 612, the block 9 is blocked and fixed in the mounting hole 611, and then the plug 613 is tightened. The other end of the steel wire rope 8 passes through the connecting block 71 and is tied and fixed to make the steel wire rope 8 taut.

[0038] Reference Figure 5 This is a schematic diagram of the state of this embodiment, wherein this embodiment is installed in a hopper. Figure 5 A is the qualified product material bin, B is the unqualified product material bin, and C is the middle partition (this is the prior art). During installation, the shaft 1 is located above the middle partition, so that the height difference between the highest point of the steel wire rope 8 and the top of the middle partition is about 5 cm. After actual use, this distance will not affect the passage of materials. At the same time, it is ensured that after the shaft 1 rotates 180 degrees Celsius, the steel wire rope 8 rotates to the lowest point and just touches the top of the middle partition.

[0039] (ii) When in use, some materials will fall on the wire rope 8, especially when sorting materials that are easy to bend or have handles, such as peppers with handles, Chinese medicinal materials, edamame clips, etc., the materials are easy to hang on the wire rope 8. At this time, the motor 2 drives the shaft 1 to rotate clockwise, referring to Figure 5 After rotating clockwise, the wire rope 8 is first located above the unqualified material bin B, and some materials may fall down due to the rotation of the wire rope 8 and fall into the unqualified material bin B.

[0040] When the rotating shaft 1 continues to rotate, the collision surface 73 of the connecting block 71 contacts the baffle 75, and the baffle 75 is fixed. At this time, the connecting block 71 moves along the spring rod 74 and is stored back in the lifting hole 621 of the second fixer 62. The spring on the spring rod 74 is compressed. At the same time, because the central angle of the arc-shaped collision surface 73 is ninety degrees, when the connecting block 71 continues to rotate with the rotating shaft 1, after the collision surface 73 and the baffle 75 are disengaged, the spring restoring force on the spring rod 74 causes the connecting block 71 to reset. It is a slow process for the baffle 75 to push the connecting block 71 into the lifting hole 621, but when the baffle 75 and the collision surface 73 are disengaged, the connecting block 71 is quickly reset, and the wire rope 8 moves quickly at this time, so the material hanging on the wire rope 8 will be shaken off and enter the unqualified material bin B below.

[0041] Even if a small amount of material still falls on the top of the middle partition C, when the wire rope 8 rotates to the bottom, it passes over the middle partition C and pushes the material away. That is, this embodiment is installed in the hopper, located above the middle partition. Since it is close to the middle partition, it does not affect the separation function of the middle partition. At the same time, the material that is easily attached to the middle partition is transferred to the wire rope 8, and is transferred to the unqualified material bin B through the movement of the wire rope 8.

[0042] (III); When the connecting block 71 moves along the spring rod 74 and enters and exits the lifting hole 621, since the polyurethane elastomer 612 is arranged in the mounting hole 611 of the No. 1 fixture 61, the polyurethane elastomer 612 abuts against the stopper 9 in the initial state, so that the steel wire 8 is kept in a taut state. At the same time, when the connecting block 71 enters the lifting hole 621, the stopper 9 connected to the steel wire 8 can compress the polyurethane elastomer 612, so that the steel wire 8 moves toward one end of the No. 2 bracket 42 as a whole, so there is no need to worry about the steel wire 8 breaking.

[0043] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
