Description

Technical Field

[0001] The utility model relates to the technical field of shrimp color sorters, in particular to a rejecting device for shrimp color sorters. Background Art

[0002] The dried shrimp color sorter mainly screens the dried shrimps by color. Because the quality of dried shrimps of different colors is different, the dried shrimp color sorter usually uses a conveyor belt mechanism to send the dried shrimps into the machine for color sorting, and then uses optical principles and technology to screen out low-quality colored shrimps.

[0003] When the dried shrimp enter the color sorter, the sand and particles contained in the shrimp must first be removed to prevent the sand and particles from entering the color sorter along with the shrimp, which will cause the color sorter to be unable to screen out low-quality shrimp. Currently, most of the removal methods are to pour the dried shrimp into a clean container and have the staff check and remove obvious particles and impurities, but this method is time-consuming and reduces overall work efficiency. Utility Model Content

[0004] In response to the above problems, a removal device for a shrimp color sorter is provided. The sand, gravel and particles contained in the shrimp can be removed through the filter screen plate, and the shrimp will pass through the filter holes inside the filter screen plate and fall onto the conveyor belt for subsequent color sorting. In order to prevent the filter holes inside the filter screen plate from being blocked, the motor is used to drive the half gear to rotate, and then the half gear cooperates with the gear ring to drive it to reciprocate. The reciprocating motion of the gear ring will also drive the push rod, cleaning brush plate and connecting plate to reciprocate. The reciprocating push rod and connecting plate cooperate with the connecting block to continuously drive the filter screen plate to vibrate, effectively preventing the filter holes inside the filter screen plate from being blocked by sand, gravel and particles.

[0005] In order to solve the problems of the existing technology, the utility model provides a rejection device for a shrimp color sorter, comprising a color sorter body, the top of the color sorter body is connected to a feed hopper, the top of the feed hopper is connected to a distribution pipe, support blocks are provided on the inner walls on both sides of the color sorter body, and each of the support blocks is symmetrically provided with through holes for installing a down-pressing rod.

DETAILED DESCRIPTION

[0020] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 6 As shown, the utility model provides:

[0022] A rejection device for a shrimp color sorter includes a color sorter body 1. The top of the color sorter body 1 is connected to a feed hopper 3, and the top of the feed hopper 3 is connected to a distribution pipe 4. Support blocks 9 are provided on the inner walls of both sides of the color sorter body 1. Each support block 9 has a through hole symmetrically opened inside for installing a down-pressing rod 8. A filter screen plate 5 is provided on the top of the down-pressing rod 8. A reset spring 7 is provided on the outside of the down-pressing rod 8. One end of the reset spring 7 is connected to the bottom of the filter screen plate 5, and the other end of the reset spring 7 is connected to the top of the support block 9.

[0023] The feed hopper 3 is equipped with a distribution pipe 4 to ensure that the dried shrimp are evenly distributed when poured into the filter screen 5, preventing the shrimp from piling up together. This can prevent the shrimp from squeezing each other during the subsequent screening process and affecting the screening effect. The filter screen 5 is used to filter out sand and granular impurities contained in the dried shrimp. The screened shrimp will fall through the small holes in the screen and fall onto the conveyor belt below. The conveyor belt then transports the shrimp to the next processing link for color sorting.

[0024] like Figure 1 and Figure 2 As shown, a somewhat symmetrical guide plate 6 is provided on the top of the filter screen plate 5 , and notches corresponding to the guide plates 6 are opened on both sides of the outer wall of the color sorter body 1 .

[0025] The guide plates 6 on both sides of the filter screen plate 5 are used to discharge impurities such as sand and particles through the gaps in the side wall of the color sorter body 1, which can prevent these impurities from accumulating on the top of the filter screen plate 5, thereby avoiding pushing and squeezing pressure on the top of the screen plate.

[0026] like Figure 3As shown, a through hole for the push rod 10 to move is opened on the outer wall of one side of the color sorter body 1, a cleaning brush plate 14 is provided at one end of the push rod 10, a connecting plate 12 is provided on the outside of the push rod 10, and a symmetrical connecting block 13 is rotatably provided on the side wall of the connecting plate 12, and the other end of the connecting block 13 is rotatably connected to the top of the filter screen plate 5.

[0027] Through the reciprocating motion of the push rod 10, the cleaning brush plate 14 and the connecting plate 12, the reciprocating push rod 10 and the connecting plate 12 cooperate with the connecting block 13 to continuously drive the filter screen plate 5 to vibrate, effectively preventing the filter holes inside the filter screen plate 5 from being blocked by sand and particles, and these filtered sand and particles will be swept to both sides of the filter screen plate 5 under the reciprocating work of the cleaning brush plate 14.

[0028] like Figure 3 and Figure 5 As shown, the inner wall of the color sorter body 1 is provided with symmetrical telescopic rods 11 , and the telescopic ends of the telescopic rods 11 are connected to the side walls of the cleaning brush plate 14 .

[0029] The well-designed telescopic rod 11 can significantly improve the stability and flexibility of the cleaning brush plate 14 during movement. The telescopic rod 11 is made of high-strength and corrosion-resistant materials, ensuring its durability and reliability in various usage environments.

[0030] like Figure 6 As shown, a drive box 2 is provided on the outer wall of the color sorter body 1, a gear ring 16 is slidably provided inside the drive box 2, one side of the gear ring 16 is connected to one end of the push rod 10, a motor 15 is provided inside the drive box 2, and an output shaft of the motor 15 is provided with a half gear 17 meshing with the gear ring 16.

[0031] The motor 15 drives the half gear 17 to rotate, and the half gear 17 cooperates with the gear ring 16 to drive it to reciprocate. The reciprocating motion of the gear ring 16 also drives the push rod 10 to reciprocate.

[0032] like Figure 6 As shown, a limiting slide rail 18 for the gear ring 16 to move is provided inside the driving box 2.

[0033] The precisely designed limit slide 18 can effectively prevent the gear ring 16 from positional displacement during movement, ensuring stable operation and precise positioning of mechanical components. The limit slide 18 is usually made of high-strength, wear-resistant materials, such as high-quality steel or special alloys, to withstand the various forces and friction generated by the gear ring 16 during movement. The design of this slide fully considers the movement trajectory and required accuracy of the gear ring 16. Through precise dimensional control and surface treatment, it provides a smooth and stable movement path for the gear ring 16. The limit slide 18 can contain guide grooves or rolling elements, such as balls or sliders, to reduce friction and enhance the smoothness of sliding, while limiting the displacement of the gear ring 16 in the horizontal or vertical direction.

[0034] Staff: First, the staff will pour the shrimps that need to be screened from the feed hopper 3. The shrimps that enter the feed hopper 3 will fall evenly on the top of the filter screen plate 5 under the action of the distribution pipe 4 to prevent the shrimps from being pushed together when pouring, affecting the subsequent screening. After that, the filter screen plate 5 can be used to remove the sand and particles contained in the shrimps, and the shrimps will pass through the filter holes inside the filter screen plate 5 and fall onto the conveyor belt for subsequent color sorting. In order to prevent the filter holes inside the filter screen plate 5 from being blocked, the motor 15 is used to drive the half gear 17 to rotate, and then the half gear 17 cooperates with the gear ring 16 to drive its reciprocating motion. , and the reciprocating motion of the gear ring 16 will also drive the push rod 10, the cleaning brush plate 14 and the connecting plate 12 to reciprocate. The reciprocating push rod 10 and the connecting plate 12 cooperate with the connecting block 13 to continuously drive the filter screen plate 5 to vibrate, effectively preventing the filter holes inside the filter screen plate 5 from being blocked by sand and particles. The filtered sand and particles will be swept to both sides of the filter screen plate 5 under the reciprocating work of the cleaning brush plate 14, and then the guide plates 6 on both sides of the filter screen plate 5 can be used to remove these sand and particles through the gaps in the side walls of the color sorter body 1, preventing the top of the filter screen plate 5 from pushing a large amount of sand and particles.

[0035] The above embodiments merely illustrate one or several implementations of a rejecting device for a shrimp color sorter according to the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
