Description

Technical Field

[0001] The utility model relates to the technical field of snail processing, in particular to a screening machine for snail processing. Background Art

[0002] Snails often live in lakes, ponds, paddy fields and slow-flowing rivers where they are warm in winter and cool in summer, with soft bottom soil and abundant bait. Artificially bred snails can be raised in special ponds, or in natural rice fields, swamps and ditches. They can also be raised together with fish. If they are raised in rice fields, wire or plastic nets should be installed at the inlets and outlets for the purpose of control. Snails are rich in nutrients, and people have become more and more fond of them in recent years. After the snails are caught, they often need to go through a screening process to separate the snails by size for subsequent processing and production.

[0003] Currently, snails are usually screened by vibrating screens or drum screens. However, the following problems may occur during screening: (1) Since snails are conical in shape and have thread-like patterns on their surfaces, when the snails are fed into the screening device, they squeeze each other and cause the feed port to be blocked; (2) When screening, the snails will block the holes in the screen plate, reducing the screening speed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a screening machine for processing snails, which has the advantages of regular and quantitative conveying of snails and enhanced screening effect, avoiding the problems of blockage of the device feed port and blockage of the screen plate.

[0005] In order to achieve the purpose of regular and quantitative delivery of snails and enhance the screening effect, the utility model provides the following technical solutions:

[0006] A screening machine for processing snails, comprising a main frame, a screening assembly being slidably connected to the inner wall of the main frame, a first spring being fixedly connected between the screening assembly and the inner wall of the main frame, and further comprising:

[0007] The side wall of the main frame is fixedly connected to a servo motor, the end of the servo motor located inside the main frame is fixedly connected to a rotating shaft, the side wall of the rotating shaft is fixedly connected to a rotating column, the top of the main frame above the rotating column is slidably connected to a sliding column, and the sliding column extends into the inner cavity of the main frame, the bottom end of the sliding column is fixedly connected to a collision block, a second spring is fixedly connected between the end of the sliding column and the main frame, a feed pipe is fixedly connected to the top of the main frame, a conical port is fixedly connected to the top of the feed pipe, and an L-shaped column is fixedly connected to the side wall of the sliding column located inside the main frame, and The L-shaped column is located in the inner cavity of the feed pipe, and a block is fixedly connected to the end of the L-shaped column. When the block is in the inner cavity of the feed pipe, it can hinder the snail from falling. After the rotating column collides with the collision block, the sliding column drives the block to move upward. After the block moves to the tapered mouth, the snail can fall into the screening component on the inner wall of the main frame, and then under the elastic force of the second spring, the block returns to its original position and continues to hinder the snail from falling. This not only avoids blockage of the feed port by too many snails, but also allows the snails to fall on the screening component effectively and quantitatively for screening, thereby enhancing the screening effect.

[0008] According to some embodiments, the screening assembly includes a mounting frame and a sieve plate, the mounting frame is slidably mounted on the inner wall of the main frame, and the mounting frame is fixedly connected to the first spring, the inner wall of the mounting frame is slidably connected with the sieve plate, the top of the mounting frame is fixedly connected with a threaded bolt, the mounting frame and the sieve plate are fixedly connected by the threaded bolt, one side of the top of the sieve plate is fixedly connected with a limiting plate, the side wall of the main frame is slidably connected with a collecting box, the inner wall of the main frame below the sieve plate is fixedly connected with a unloading plate, and the unloading plate is arranged in an inclined shape, after the rotating column collides with the sieve plate, the sieve plate slides down, causing the first spring to be compressed and generate a rebound force, and after the rotating column moves away from the sieve plate, the sieve plate vibrates up and down under the action of the rebound force of the first spring, thereby enhancing the screening effect of the sieve plate and preventing snails from being stuck in the filter holes of the sieve plate.

[0009] According to some embodiments, the mounting frame and the screen plate are arranged in an inclined shape and inclined toward the collecting box, the top of the limiting plate is arranged in an arc shape, the collision block is arranged in an arc shape, the top of the card block is arranged in an arc shape, and the diameter of the card block is equal to the inner diameter of the feed pipe. The inclined setting of the screen plate allows the snails to roll and be screened on the screen plate, and then fall into the inner cavity of the collecting box. Beneficial Effects

[0010] The utility model provides a screening machine for processing snails, which has the following beneficial effects:

[0011] In the screening machine for processing snails, the rotating shaft drives the rotating column to collide with the collision block, thereby causing the sliding column to slide upward, and the second spring is stretched. The L-shaped column drives the blocking block to slide upward to the tapered mouth, and the snails enter the main frame through the feeding pipe. After the rotating column moves away from the collision block, the blocking block returns to its original position and continues to prevent the snails from entering the inner cavity of the main frame. This is repeated, so that the snails fall into the main frame in an orderly and quantitative manner, which can prevent the snails from blocking the feeding pipe when feeding.

[0012] In the screening machine for processing snails, the rotating column collides with the sieve plate, causing the sieve plate and the mounting frame to slide downward, squeezing the first spring to generate a rebound force; when the rotating column moves away from the sieve plate, the sieve plate swings up and down under the rebound force of the first spring, thereby enhancing the screening effect of the sieve plate and preventing the snails from getting stuck on the sieve plate.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Reference Figure 1-3 A screening machine for processing snails comprises a main frame 1, a screening assembly is slidably connected to the inner wall of the main frame 1, a first spring 101 is fixedly connected between the screening assembly and the inner wall of the main frame 1, and further comprises:

[0019] The side wall of the main frame 1 is fixedly connected with a servo motor 2, and the end of the servo motor 2 located inside the main frame 1 is fixedly connected with a rotating shaft 201, and the side wall of the rotating shaft 201 is fixedly connected with a rotating column 202, and the top of the main frame 1 above the rotating column 202 is slidably connected with a sliding column 203, and the sliding column 203 extends toward the inner cavity of the main frame 1, and the bottom end of the sliding column 203 is fixedly connected with a collision block 204, and a second spring 209 is fixedly connected between the end of the sliding column 203 and the main frame 1;

[0020] A feed pipe 205 is fixedly connected to the top of the main frame 1, and a conical port 206 is fixedly connected to the top of the feed pipe 205;

[0021] An L-shaped column 207 is fixedly connected to the side wall of the internal sliding column 203 located on the main frame 1, and the L-shaped column 207 is located in the inner cavity of the feed pipe 205, and a clamping block 208 is fixedly connected to the end of the L-shaped column 207;

[0022] It should be noted that: the snail is placed into the feed tube 205 through the conical opening 206. Due to the restriction of the block 208, the snail will not enter the inner cavity of the main frame 1 at this time. Then the servo motor 2 is turned on, and the servo motor 2 will drive the rotating shaft 201 to rotate. The rotating shaft 201 drives the rotating column 202 on its side wall to rotate. When the rotating column 202 rotates, it will collide with the collision block 204, thereby causing the sliding column 203 on the top of the collision block 204 to slide upward, the second spring 209 is stretched, and the L-shaped column 207 drives the block 208 to slide upward at the same time. After the block 208 slides upward into the tapered mouth 206, the snails will enter the surface of the screening component on the inner wall of the main frame 1 through the feed pipe 205. After the rotating column 202 moves away from the collision block 204, under the rebound force of the second spring 209, the sliding column 203 drives the L-shaped column 207 and the block 208 back to their original positions, continuing to prevent the snails from entering the inner cavity of the main frame 1. This is repeated, so that the snails fall onto the screening component in an orderly and quantitative manner for screening, thereby enhancing the screening effect and avoiding the snails from blocking the feed pipe 205 when feeding.

[0023] Reference Figure 1-3 The screening assembly includes a mounting frame 3 and a sieve plate 301, the mounting frame 3 is slidably mounted on the inner wall of the main frame 1, and the mounting frame 3 is fixedly connected to the first spring 101, and the inner wall of the mounting frame 3 is slidably connected to the sieve plate 301;

[0024] A threaded bolt 302 is fixedly connected to the top of the mounting frame 3, the mounting frame 3 and the sieve plate 301 are fixedly connected via the threaded bolt 302, and a limiting plate 303 is fixedly connected to one side of the top of the sieve plate 301;

[0025] The side wall of the main frame 1 is slidably connected with a collecting box 304, and the inner wall of the main frame 1 below the screen plate 301 is fixedly connected with a blanking plate 305, and the blanking plate 305 is arranged in an inclined shape;

[0026] It should be noted that: the sieve plate 301 is placed into the inner cavity of the mounting frame 3 and fixed with the threaded bolt 302, and the sieve plate 301 can be used to screen the snails, and when the rotating shaft 201 drives the rotating column 202 to rotate, the rotating column 202 will collide with the sieve plate 301, thereby causing the sieve plate 301 and the mounting frame 3 to slide downward, squeezing the first spring 101, causing it to generate a rebound force, and when the rotating column 202 is driven away from the sieve plate 301, the sieve plate 301 swings up and down under the action of the rebound force of the first spring 101, thereby enhancing the screening effect of the sieve plate 301 and preventing the snails from getting stuck on the sieve plate 301, wherein the limit plate 303 can prevent the snails from sliding too fast on the surface of the sieve plate 301, affecting the screening effect, and qualified snails will slide from the sieve plate 301 to the inner cavity of the collection box 304, and unqualified screws will fall from the sieve plate 301 to the surface of the blanking plate 305, and then slide to the outside of the main frame 1.

[0027] Reference Figure 1-3 , the mounting frame 3 and the sieve plate 301 are arranged in an inclined shape and inclined toward the collecting box 304, and the top of the limiting plate 303 is arranged in an arc shape;

[0028] The collision block 204 is configured to be arc-shaped, the top of the clamping block 208 is configured to be arc-shaped, and the diameter of the clamping block 208 is equal to the inner diameter of the feed pipe 205;

[0029] It should be noted that the inclined setting of the sieve plate 301 can make the snails roll on the sieve plate 301 to achieve the screening effect. The collision block 204 is set to an arc shape to facilitate the collision between the rotating column 202 and the collision block 204, and the top of the block 208 is set to an arc shape to prevent the snails from staying on the top of the block 208 and not falling easily.

[0030] Operation method: put the snail into the feed pipe 205 through the conical opening 206. Due to the restriction of the block 208, the snail will not enter the inner cavity of the main frame 1 at this time. Then turn on the servo motor 2, which will drive the rotating shaft 201 to rotate. The rotating shaft 201 drives the rotating column 202 on its side wall to rotate. When the rotating column 202 rotates, it will collide with the collision block 204, thereby causing the sliding column 203 on the top of the collision block 204 to slide upward, the second spring 209 is stretched, and the L-shaped column 207 drives the block 208 to slide upward at the same time. After the block 208 slides upward into the tapered opening 206, the snails will enter the surface of the screening component on the inner wall of the main frame 1 through the feed pipe 205. After the rotating column 202 moves away from the collision block 204, under the rebound force of the second spring 209, the sliding column 203 drives the L-shaped column 207 and the block 208 back to their original positions, continuing to prevent the snails from entering the inner cavity of the main frame 1. This is repeated, so that the snails fall into the screening component in an orderly and quantitative manner for screening, thereby enhancing the screening effect and preventing the snails from blocking the feed pipe 205 when feeding.

[0031] When the snails fall onto the sieve plate 301, they are screened, and when the rotating shaft 201 drives the rotating column 202 to rotate, the rotating column 202 collides with the sieve plate 301, thereby causing the sieve plate 301 and the mounting frame 3 to slide downward, squeezing the first spring 101 to generate a rebound force, and when the rotating column 202 is driven away from the sieve plate 301, the sieve plate 301 shakes up and down under the rebound force of the first spring 101, thereby enhancing the screening effect of the sieve plate 301 , to prevent the snails from getting stuck on the sieve plate 301, wherein the limit plate 303 can prevent the snails from sliding too quickly on the surface of the sieve plate 301, affecting the screening effect, and the qualified snails will slide from the sieve plate 301 to the inner cavity of the collection box 304, and the unqualified screws will fall from the sieve plate 301 to the surface of the blanking plate 305, and then slide to the outside of the main frame 1. When installing the sieve plate 301, the sieve plate 301 is placed in the inner cavity of the mounting frame 3 and fixed with the threaded bolt 302, and the same applies to disassembly.
