Description

Technical Field

[0001] This invention relates to the field of nut processing equipment technology, specifically a multi-stage sorting device based on nut processing. Background Technology

[0002] This multi-stage nut sorting device is used for grading and removing impurities throughout the entire process of large-scale nut processing, replacing manual sorting. It is suitable for various nut raw materials such as walnuts, almonds, and cashews. The multi-layer sieve structure with decreasing aperture divides nuts into multiple specifications, including large, medium, small, and broken kernels, according to particle size. The entire set of equipment operates automatically and continuously, with high grading accuracy, reducing nut damage from bumps and knocks. It completes the impurity removal, size grading, and defective product rejection processes in one go, significantly reducing labor costs and standardizing the separation of raw materials of different grades, providing well-organized materials for subsequent roasting, packaging, and graded sales. Existing multi-stage nut sorting equipment relies on an external motor to drive a rotating disc and a scoop to circulate and feed nuts. After the nuts fall onto the threaded rod, they are fed into an inclined rotating grading and screening cylinder. The cylinder is graded by size through different apertures. The screening cylinder continuously and uniformly tumbles the material with the rotating rod to complete the sorting. However, during the sorting process of conventional equipment, nut particles are easily embedded in the holes of the cylinder, causing material jamming. The jammed nuts cannot fall off on their own, and the continuous blockage of the screen holes will reduce the effective screening area, hinder the normal rolling and grading of materials, and significantly reduce the nut sorting throughput and grading accuracy. Frequent blockages also require manual shutdown to clean the screen cylinder, interrupting the continuous processing flow and seriously reducing the smoothness of multi-stage nut sorting operations and overall production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-stage sorting device based on nut processing to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a multi-stage sorting device for nut processing, comprising a main body, a rotating rod rotatably connected to the top of the main body, a screening cylinder fixedly connected to the outer surface of the rotating rod, and further comprising: An active mechanism is installed on the outer surface of the rotating rod. The active mechanism is used to agitate the nuts inside the screening cylinder. The active mechanism includes several protruding blocks fixedly connected to the outer surface of the rotating rod, and the protruding blocks are distributed circumferentially around the rotating rod. The docking mechanism is installed on the side wall of the active mechanism. The docking mechanism is designed to reduce the chance of nuts being crushed by the active mechanism during movement. There are five protruding blocks, which are designed to provide propulsion for the movement of subsequent parts.

[0005] Furthermore, the main body includes: The feeding assembly is located on the side wall of the main body and is used to feed material into the screening cylinder. The receiving component is located at the bottom of the main body and is used to receive nuts that have been screened out from the screening cylinder. The device includes three spatulas, which feed the nuts at a constant speed.

[0006] Furthermore, active institutions also include: The actuating component is located inside the screening tube and is used to agitate the nuts. The blocking component is located on the side wall of the drive component and is used to prevent nuts from being sieved prematurely.

[0007] Furthermore, the partner organizations include: An anti-pinch component is installed on the side wall of the drive component. The anti-pinch component is designed to reduce the occurrence of nut breakage.

[0008] Furthermore, the feeding assembly includes a rotating disk rotatably connected to the side wall of the main body, and several scoops are fixedly connected to the outer surface of the rotating disk; Several spatulas are distributed in a circle around a rotating disk, and threaded rods are connected to the side wall of the rotating disk for transmission.

[0009] Furthermore, the receiving assembly includes a movable rod rotatably connected to the bottom of the main body, and a receiving bin is slidably connected to the outer surface of the movable rod.

[0010] Furthermore, the driving component includes several spring pieces disposed on the side wall of the protruding block, and a covering cylinder is fixedly connected to the end of the spring piece away from the protruding block, and the covering cylinder is sleeved on the outer surface of the protruding block.

[0011] Furthermore, several baffles are fixedly connected to the outer surface of the covering cylinder, and the baffles are distributed circumferentially around the protruding block; Rubber sheets are fixedly connected to the side walls of the baffle plate; The device includes four baffles, which are used to stir the nuts inside the sieving cylinder.

[0012] Furthermore, the blocking assembly includes a rubber sheet fixedly connected to the side wall of the blocking plate, and a grid plate is fixedly connected to the side wall of the rubber sheet; A roller is rotatably connected to the end of the rubber sheet and the baffle away from the barrier.

[0013] Furthermore, a delay plate is fixedly connected to the side wall of the baffle plate, and a push plate is fixedly connected to the side wall of the delay plate; The sidewall of the delay plate has several conveying holes, which are equidistantly distributed along the baffle plate. The placement of several baffles slows down the flow of the nuts.

[0014] The present invention has the following beneficial effects: 1. In this invention, the rubber sheet undergoes a certain deformation when it is squeezed against the inner wall of the screening cylinder during the movement of the baffle plate. When the screening cylinder rotates, the rubber sheet scrapes against the inner wall of the screening cylinder. At the same time, due to the friction between the rubber sheet and the inner wall of the screening cylinder, the baffle plate and the covering cylinder will vibrate. The scraping of the inner wall of the screening cylinder by the rubber sheet will also move the nuts stuck in the holes of the screening cylinder. The vibration of the covering cylinder and the baffle plate will loosen the nuts stuck in the holes of the screening cylinder, thereby reducing the situation of nuts getting stuck during sorting and causing a decrease in sorting efficiency, and further improving the smoothness of multi-stage nut sorting.

[0015] 2. In this invention, the outer side of the rubber plate is deformed by the pressure of the nuts. The pressure of the rubber plate will push the nuts on the inner side of the rubber plate to the outer side of the screening cylinder. When the rubber plate and the baffle rotate synchronously with the screening cylinder, the rollers on the rubber plate and the baffle will contact the screening cylinder. When the rubber plate pushes the nuts, the baffle will further block the nuts. When the rubber plate and the baffle rotate to 180 degrees, the baffle will guide the nuts to the bottom of the screening cylinder, further reducing the situation where the nuts move away from the screening cylinder in advance when they are pushed by the baffle, and further improving the stability of the discharge position of the nuts during screening.

[0016] 3. In this invention, gaps will appear when the baffles rotate. At this time, nuts may be crushed by the two baffles in different positions when passing through. Since the side wall of the delay plate is provided with a push plate, when the nuts pass through the delay plate, they will come into contact with the push plate. When the two baffles approach each other, they will squeeze the push plate and cause it to deform to a certain extent. The deformation of the push plate will cause the nuts to deviate from their original positions, thereby reducing the chance of nuts being crushed by the baffles during sorting, and thus further improving the integrity of nut sorting.

[0017] 4. In this invention, when the push plate passes through the gap between the baffles, the baffles will deform. After the baffles pass through the gap, the deformation of the push plate will quickly return to its original position. At this time, the push plate will tap the nuts inside the screening cylinder. At the same time, the friction between the rubber sheet and the inside of the screening cylinder will cause the covering cylinder and the baffles to vibrate. The nuts come into contact with the baffles. The vibration of the baffles and the tapping of the push plate will accelerate the flow speed of the nuts in the screening cylinder, thereby further improving the flowability of the nuts during sorting.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8As shown, the present invention is a multi-stage sorting device based on nut processing, including a main body 1, a rotating rod 101 rotatably connected to the top of the main body 1, a screening cylinder 102 fixedly connected to the outer surface of the rotating rod 101, and further including: Active mechanism 2 is installed on the outer surface of rotating rod 101. Active mechanism 2 is used to agitate the nuts inside screening cylinder 102. The active mechanism 2 includes a number of protruding blocks 211 fixedly connected to the outer surface of the rotating rod 101, and the number of protruding blocks 211 are distributed circumferentially around the rotating rod 101. The docking mechanism 3 is installed on the side wall of the active mechanism 2. The docking mechanism 3 is designed to reduce the chance of nuts being crushed by the active mechanism 2 during movement. Five protruding blocks 211 are provided, and the purpose of the protruding blocks 211 is to provide a driving force for the movement of subsequent parts.

[0024] Entity 1 includes: Feeding assembly 11 is disposed on the side wall of the main body 1, and the feeding assembly 11 is disposed for feeding material into the screening cylinder 102; The receiving component 12 is located at the bottom of the main body 1. The receiving component 12 is used to receive nuts screened out from the screening cylinder 102. Among them, there are three spatulas 112, which convey nuts at a constant speed.

[0025] Active mechanism 2 also includes: Drive component 21 is located inside the screening cylinder 102 and is used to agitate the nuts. The blocking component 22 is disposed on the side wall of the driving component 21. The blocking component 22 is used to prevent nuts from being sieved prematurely.

[0026] The third docking organization includes: An anti-pinch component 31 is disposed on the side wall of the drive component 21. The anti-pinch component 31 is disposed to reduce the occurrence of nut breakage.

[0027] The feeding assembly 11 includes a rotating disk 111 rotatably connected to the side wall of the main body 1, and a plurality of scoops 112 are fixedly connected to the outer surface of the rotating disk 111. Several scoops 112 are distributed circumferentially around a rotating disk 111. The side wall of the rotating disk 111 is connected to a threaded rod 113. The operator first starts the external motor, which drives the rotating disk 111 to rotate through the external gear. The rotation of the rotating disk 111 drives the scoops 112 to move synchronously. When the scoops 112 rotate, they scoop up the nuts.

[0028] The receiving assembly 12 includes a movable rod 121 rotatably connected to the bottom of the main body 1, and a receiving bin 122 is slidably connected to the outer surface of the movable rod 121.

[0029] The driving component 21 includes several spring pieces 212 disposed on the side wall of the protruding block 211. A covering cylinder 213 is fixedly connected to one end of the spring piece 212 away from the protruding block 211. The covering cylinder 213 is sleeved on the outer surface of the protruding block 211. When the nut is not inserted, the blocking plate 214 will rotate synchronously on the rotating rod 101 under the setting of the protruding block 211 and the external spring pieces 212. When the nut comes into contact with the blocking plate 214, the weight of the nut itself will push the nested part formed by the blocking plate 214 and the covering cylinder 213 to the other side.

[0030] A number of baffle plates 214 are fixedly connected to the outer surface of the covering cylinder 213, and the baffle plates 214 are distributed circumferentially around the protruding block 211. A rubber sheet 215 is fixedly connected to the side wall of the baffle plate 214; Four baffle plates 214 are provided. The baffle plates 214 are used to stir the nuts inside the screening cylinder 102. The movement mode of the baffle plates 214 will change after the connection relationship between the protrusion block 211 and the spring piece 212 changes. At this time, the baffle plates 214 will not rotate synchronously with the screening cylinder 102. The baffle plates 214 will remain stationary inside the screening cylinder 102. When the baffle plates 214 are pushed, the rubber piece 215 at one end will contact the inner wall of the screening cylinder 102.

[0031] The blocking assembly 22 includes a rubber plate 221 fixedly connected to the side wall of the blocking plate 214, and a grid plate 222 is fixedly connected to the side wall of the rubber plate 221. A roller 223 is rotatably connected to the end of the rubber sheet 221 and the baffle 222 away from the blocking plate 214.

[0032] A delay plate 311 is fixedly connected to the side wall of the blocking plate 214, and a push plate 312 is fixedly connected to the side wall of the delay plate 311. The side wall of the delay plate 311 is provided with a number of conveying holes 313, which are equidistantly distributed along the baffle plate 214. The arrangement of several baffles 214 slows down the flow rate of the nuts. Under the influence of the inclined structure of the screening cylinder 102, the nuts move towards the delay plate 311 and come into contact with the delay plate 311. The conveying holes 313 on the delay plate 311 can maintain the flow of the nuts during screening. At the same time, the arrangement of the delay plate 311 can slow down the conveying speed of some nuts inside the screening cylinder 102.

[0033] In use, the operator first starts the external motor, which drives the rotating disk 111 to rotate through the external gears. The rotation of the rotating disk 111 drives the shovel 112 to move synchronously. When the shovel 112 rotates, it scoops up the nuts. The nuts scooped up by the shovel 112 rotate synchronously with the rotating disk 111. When it reaches the top of the rotating disk 111, the nuts in the shovel 112 will fall towards the threaded rod 113 due to gravity. The rotation of the threaded rod 113 will transport the nuts into the screening cylinder 102. The screening cylinder 102 will rotate around the rotating rod 101 under the drive of the external motor. The screening cylinder 102 is set at an inclination. After the nuts enter, they will slide away from the rotating disk 111 along the inclination angle. The rotation of the screening cylinder 102 will move and tumble the nuts. The holes on the screening cylinder 102 are of different sizes, thus completing the multi-stage sorting of nuts.

[0034] When the nuts enter the screening cylinder 102, they first come into contact with the side wall of the baffle plate 214. Before the nuts are placed in, the baffle plate 214 rotates synchronously due to the protrusion 211 on the rotating rod 101 and the external spring 212. However, when the nuts contact the baffle plate 214, the weight of the nuts pushes the nested part formed by the baffle plate 214 and the covering cylinder 213 to the other side. At this time, the spring 212 inside the covering cylinder 213 deforms, and the locking structure formed with the protrusion 211 fails. The movement of the baffle plate 214 changes after the connection between the protrusion 211 and the spring 212 changes. The baffle plate 214 will no longer rotate synchronously with the screening cylinder 102; instead, it will remain stationary inside the screening cylinder 102. When in motion, the rubber sheet 215 at one end will contact the inner wall of the screening cylinder 102. When the baffle plate 214 moves, the rubber sheet 215 will deform under the pressure of the inner wall of the screening cylinder 102. When the screening cylinder 102 rotates, the rubber sheet 215 will scrape the inner wall of the screening cylinder 102. At the same time, due to the friction between the rubber sheet 215 and the inner wall of the screening cylinder 102, the baffle plate 214 and the covering cylinder 213 will vibrate. The scraping of the inner wall of the screening cylinder 102 by the rubber sheet 215 will also move the nuts stuck in the holes of the screening cylinder 102. The vibration of the covering cylinder 213 and the baffle plate 214 will loosen the nuts stuck in the holes of the screening cylinder 102, so as to reduce the situation of nuts getting stuck during sorting and thus reduce the decrease in sorting efficiency, and further improve the smoothness of multi-stage nut sorting.

[0035] When nuts enter the screening cylinder 102 and come into contact with the baffle plate 214, they will also come into contact with the rubber plate 221. If the number of nuts is insufficient or their weight is insufficient, the baffle plate 214 will not be pushed. Instead, the baffle plate 214 will rotate synchronously with the screening cylinder 102. The movement of the baffle plate 214 will push the nuts towards the top of the screening cylinder 102. During this process, some nuts may leak out through the holes slightly above the top of the screening cylinder 102. Due to the design of the rubber plate 221, when nuts enter, they will come into contact with it, and some nuts will enter the gap formed between the rubber plate 221 and the baffle plate 214. When the gap between the rubber plate 221 and the baffle plate 214 is located at the bottom of the screening cylinder 102, the rubber plate 221... The outer side of the 1 will be deformed by the pressure of the nuts. The pressure of the rubber plate 221 will push the nuts inside the rubber plate 221 to the outside of the screening cylinder 102. When the rubber plate 221 and the baffle plate 222 rotate synchronously with the screening cylinder 102, the rollers 223 on the rubber plate 221 and the baffle plate 222 will contact the screening cylinder 102. When the rubber plate 221 pushes the nuts, the baffle plate 222 will further block the nuts. When the rubber plate 221 and the baffle plate 222 rotate to 180 degrees, the baffle plate 222 will guide the nuts to the bottom of the screening cylinder 102, further reducing the situation where the nuts move away from the screening cylinder 102 in advance when they are pushed by the baffle plate 214, and further improving the stability of the discharge position of the nuts during screening.

[0036] When the nuts enter the screening cylinder 102, they first enter the area of ​​the first set of baffles 214. Under the influence of the inclined structure of the screening cylinder 102, the nuts move towards the delay plate 311 and come into contact with it. The conveying holes 313 on the delay plate 311 can maintain the flow of the nuts during screening. At the same time, the setting of the delay plate 311 can slow down the conveying speed of some nuts inside the screening cylinder 102. Since the baffles 214 are divided into multiple segments and the movement between the baffles 214 is not continuous, it will cause the baffles 214 to rotate... When the nuts pass through the barrier plates 214, gaps may appear. At this time, the nuts may be crushed by the two barrier plates 214 in different positions. Since the side wall of the delay plate 311 is provided with a push plate 312, when the nuts pass through the delay plate 311, they will come into contact with the push plate 312. When the two barrier plates 214 approach each other, they will squeeze the push plate 312 and cause it to deform to a certain extent. The deformation of the push plate 312 will cause the nuts to deviate from their original positions, thereby reducing the chance of the nuts being crushed by the barrier plates 214 during sorting, and further improving the integrity of nut sorting.

[0037] During the sorting process, the flow rate of nuts inside the screening cylinder 102 may be reduced due to the influence of multiple baffles 214 and delay plates 311. When the push plate 312 passes through the gap between the baffles 214, the baffles 214 will deform. After the baffles 214 pass through the gap, the deformation of the push plate 312 will quickly return to its original position. At this time, the push plate 312 will tap the nuts inside the screening cylinder 102. At the same time, the friction between the rubber sheet 215 and the inside of the screening cylinder 102 will cause the covering cylinder 213 and the baffles 214 to vibrate to a certain extent. The nuts come into contact with the baffles 214. The vibration of the baffles 214 and the tapping of the push plate 312 will accelerate the flow rate of nuts in the screening cylinder 102, thereby further improving the flowability of nuts during sorting.
