Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fast and efficient grading device for bait shrimps used for breeding of needleless squid. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present application and does not constitute prior art.

[0003] Sepiella japonica, commonly known as cuttlefish and eyefish, belongs to the phylum Molusca, class Cephalopoda, order Decapoda, family Sepiidae, genus Sepiella. Sepiella japonica was once one of the traditional "four major marine products" in my country's East China Sea fisheries. The highest annual production in Zhejiang Province has reached more than 60,000 tons, accounting for 9.3% of the total marine fishing production in the province. Since the late 1970s, due to overfishing and the destruction of spawning grounds, the production of Sepiella japonica in Zhejiang coastal fisheries has dropped sharply, and it has no fishing season and is on the verge of extinction.

[0004] Although its seed breeding technology has been relatively mature in recent years, many key technical links still need to be further optimized and upgraded. The bait series of Mansoni squid is Artemia - live mysid shrimp - small shrimp - medium-sized shrimp - larger shrimp. The life cycle is generally 5-6 months. The larvae eat Artemia and live mysid shrimp within one month after hatching, and eat shrimp of different sizes for the rest of the time (4-5 months). There is currently no corresponding compound feed available for feeding.

[0005] The palatability of bait plays an important role in the growth of organisms. For fish fry, as they grow larger, they need to be fed with large-particle compound feeds; the same is true for squid. As the squid grows slowly, the size of the bait shrimp also needs to increase accordingly. The needleless squid prefers to eat live bait, followed by floating dead bait. It does not like to eat bait that sinks to the bottom and does not move. If you feed large shrimp to small squid, the shrimp sinks to the bottom too quickly and the small squid cannot catch it; if you feed small shrimp to large squid, its demand for large-sized bait shrimp cannot be met. After we get the fresh bait shrimp from the boat boss, it is impossible to feed it to the squid all at once. It is usually frozen in a cold storage. Take out as much as needed, thaw it with water, and then feed it to the squid.

[0006] At present, the commonly used screening method is a relatively simple plastic basket. Although different sizes of basket holes can be used to screen the bait shrimp into large, medium and small sizes, it is a huge workload for screening tens of thousands of pounds of shrimp, and the screening is not thorough, and shrimps of different sizes are still easily mixed together. In this way, when feeding, unpalatable bait shrimps still need to be manually selected again, resulting in low work efficiency. In view of the shortcomings of the above traditional technology, it is necessary to establish a fast and efficient grading device for bait shrimp for breeding of needleless squid.

[0007] Prior art includes an invention patent with publication number KR100642077B1, and the invention name is "Sorting Machine Rotating Roller". This invention provides a device for sorting items by using rotating rollers, so as to accurately set the size of the sorted items by easily adjusting the interval between the rotating rollers. A sorting part has a pair of cylindrical sorting rollers, and the pair of cylindrical sorting rollers are rotatably arranged in parallel at a constant distance in a state where the rotating shaft is inclined at a desired angle relative to the ground. The driving part rotates the sorting rollers in opposite directions to each other, and the sorting part and the driving part are supported by a frame. The interval adjustment part adjusts the space formed between the sorting rollers by moving in parallel with the sorting rollers. The interval adjustment part has two pairs of bearing housings, a pair of shafts and a rotating handle. This invention easily wraps the shrimp tentacles around the rollers, which easily causes some shrimps to be unable to fall, affecting the grading effect.

[0008] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0009] The invention aims to provide a fast and efficient grading device for bait shrimps for breeding of needleless squid with good grading effect, adjustable grading speed and high shrimp survival rate.

[0010] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0011] A device for quickly and efficiently grading bait shrimps for breeding needleless squid, comprising a feeding component and a separation component, characterized in that the feeding component comprises a partitioning conveyor, the partitioning conveyor is used to convey raw materials to the separation component, a feeding box is provided on one side of the partitioning conveyor, the feeding box is used to input the raw materials into the partitioning conveyor, and the separation component is used to grade the raw materials.

[0012] Through the above design, the raw materials (i.e., bait shrimp) are transported to the separation component through the feeding group, and then the bait shrimp are graded through the separation component, and the graded bait shrimp are transferred to different storage boxes or other containers. Through the design of the feeding component, the bait shrimp is first transferred to the partition conveyor through the feeding box, and the feeding box is connected to a feeding pipe, and the raw materials (bait shrimp) are transported to the feeding box through the feeding pipe. At the same time, a discharge port is opened on the side of the feeding box close to the partition conveyor, and the discharge port is connected to a guide plate, which guides the raw materials coming out of the discharge port to the partition conveyor. The design of the feeding pipe can make it easier to feed the raw materials into the feeding box, and at the same time, it can free up more human resources. There are many ways to connect the feeding pipe to the feeding box. Furthermore, a feed pipe is connected to the bottom of the feed box, and the feed pipe inputs the raw materials from the bottom of the feed box. At the same time, a screw conveyor is provided in the feed box. The screw conveyor can push the raw materials at the bottom upward to the vicinity of the feed port through its own rotation, and convey the raw materials to the partition conveyor from the discharge port. Through the setting of the screw conveyor, the power and start-stop interval of the screw conveyor can be adjusted according to demand, which is beneficial to improving the efficiency of the overall device and reducing energy consumption or waste.

[0013] Furthermore, the separation conveyor includes a first conveyor belt, on which a plurality of separation plates or separation boxes are arranged at intervals. Through the above design, the separation plates and the separation boxes can both transport raw materials, and the separation plates and the separation boxes can separate the materials (i.e., bait shrimps) into multiple groups for transportation, which can prevent the bait shrimps from sliding off the first conveyor belt due to the small friction between the surface of the bait shrimps and the first conveyor belt under the action of gravity and water; in addition, after the materials are grouped by the separation plates and the separation boxes, the quantity (or weight) of the materials in each group can be adjusted according to the speed of subsequent grading, thereby controlling the speed of the screw conveyor and the first conveyor belt.

[0014] Furthermore, when a partition plate is used, the partition conveyor plate can be tilted upward, that is, the raw materials are transported from a low point to a high point, and part of the water together with the raw materials can flow downward along the first conveyor belt under the action of gravity, thereby reducing the overall weight of the transportation, reducing the energy consumption of the transportation, and reducing the cost of transportation. Moreover, when the water body flows to the next partition plate layer by layer under the action of gravity, when the overall partition conveyor is in operation, water will flow between each partition plate. During the flow of water, the water body can fully contact with the air after impacting the partition plate, thereby ensuring the oxygen content in the water body, thereby ensuring the survival rate of the bait shrimp during transportation on the first conveyor belt; in addition, when the water body impacts or collides with each partition plate during the flow, water vapor and fine water droplets will be generated, which can ensure the surrounding The humidity of the air can be increased and direct light can be scattered to prevent the stress reaction of the bait shrimps when encountering strong light during transportation. At the same time, the humid air can improve the adaptability of the shrimps and prevent the stress reaction of the shrimps after direct contact with the air, thereby preventing the bait shrimps from jumping out of the transportation range of the partition board due to stress reaction. At the same time, the flow and evaporation of the water body can reduce the temperature of the partition conveyor and its surroundings. When the temperature is changed, the activity intensity of the shrimps can be reduced, the shrimps' perception of the outside world can be reduced, and the stress reaction of the shrimps can be reduced. The partition conveyor can also be cooled to ensure that the temperature of the sealing motor on one side of the partition conveyor is kept within a reasonable range. At the same time, water vapor can absorb sound waves to reduce the noise interference of the staff when working for a long time.

[0015] Furthermore, when a partition box is used, the separation box can prevent shrimps from jumping out. At the same time, the separation box can effectively preserve the water body compared to the partition plate. When the number of bait shrimps is large, the survival rate of the shrimps can be improved. In addition, by setting up the partition box, the first conveyor belt of the partition conveyor does not need to be placed at an angle, and can be placed horizontally or tilted downward, thereby improving the flexibility of the placement and state of the device. Furthermore, the bottom layer or middle layer of the separation box is provided with fine holes, through which water can flow out. The fineness of the hole setting and the diameter of the hole are related to the length and speed of the first conveyor belt. When the raw materials enter the separation box through the feeding box, the remaining water in the separation box needs to ensure that the shrimps will not die during the process from the feeding point to the unloading point of the separation box. At the same time, the small holes can guide the water to flow out. After the water flows out, the water will flow down along the wall of the separation box. In this process, the surface area of ​​the water increases, which improves the evaporation efficiency and effect, and can reduce the temperature of the separation box to prevent the temperature in the box from rising when there are many shrimps, thereby preventing the shrimps from having a stress response or dying from lack of oxygen.

[0016] Furthermore, when a partition plate is used, the speed of the screw conveyor can be uniformly controlled to ensure that the amount of raw materials (i.e., bait shrimp) between each partition plate is the same; when a partition box is used, the screw conveyor belt can be started and stopped at intervals to prevent the raw materials (i.e., bait shrimp) from spilling outside the partition box, and the start and stop intervals can be controlled to ensure that the amount of raw materials (i.e., bait shrimp) in each partition box is the same or similar. This setting can reduce the overall power consumption and improve the utilization rate of energy.

[0017] According to an embodiment of the present invention, the separation component includes a dispersion component and a classification component. The dispersion component is used to disperse the raw materials transported by the separation conveyor, and the classification component is used to classify the dispersed raw materials.

[0018] After the raw materials are dispersed by the dispersing component, the dispersed raw materials can ensure their uniformity, and in the subsequent process of raw material classification, the efficiency and success rate of the classification process can be improved.

[0019] Furthermore, a plurality of receiving components are provided on one side of the grading component. The graded raw materials are received by the plurality of receiving components respectively to prevent the graded raw materials from piling up or mixing, and the receiving components can be storage boxes or other containers.

[0020] According to an embodiment of the present invention, the dispersion component includes a dispersion substrate, which is arranged at the bottom of the separation conveyor near the separation component, and the dispersion substrate is inclined toward the grading component. The dispersion substrate receives the raw materials transported by the separation conveyor through a receiving surface, and a plurality of first dispersion fins are arranged in a middle layer of the receiving surface, and the plurality of first dispersion fins are symmetrically inclined along the central axis of the receiving surface.

[0021] A plurality of symmetrically arranged second dispersing fins are arranged on the lower side of the receiving surface.

[0022] Through the above design, a dispersion substrate receiving surface is used to receive the raw materials transported by the separation conveyor, and a plurality of first dispersion fins are arranged in the middle layer of the receiving surface, and a plurality of symmetrically arranged second dispersion fins are arranged on the lower side, so that the receiving surface can be divided into three parts, the upper layer of the receiving surface is used to receive the raw materials, and the surface of the receiving surface is smooth. When the raw materials are transferred from the separation conveyor, the bait shrimp and the water body are received by the receiving surface together, and the upper side of the receiving surface is conducive to the downward movement of each component under the action of gravity. The setting of the plurality of first dispersion fins will buffer and disperse the raw materials moved from the upper layer of the receiving surface, and the plurality of first dispersion fins are symmetrically arranged along the central axis of the receiving surface and tilted to both sides, which can disperse the raw materials and make the raw materials move downward under the action of gravity. The second dispersion fins are used to further disperse and buffer the raw materials from the first dispersion fins, and the second dispersion fins arranged relatively are arranged in an inverted V shape, which further disperses the raw materials to the entire second conveyor belt, thereby improving the efficiency of grading in the grading component and preventing the occurrence of grading errors. Through the multi-stage dispersion substrate, it is possible to prevent the shrimps from being unable to be separated or classified inaccurately due to the entanglement of whiskers between the shrimps. The smooth receiving surface is conducive to the downward sliding of the bait shrimp. At the same time, a smooth water film can be formed on the surface after contacting the water body. The friction between the bait shrimp and the receiving surface can be further reduced by the setting of the water film. In addition, a water film can also be formed on the surface of the bait shrimp. The friction between the shrimp body or the shrimp whiskers can be reduced by the water film to prevent the shrimp whiskers from being entangled. At the same time, when the bait shrimp passes through the first dispersing fin and the second dispersing fin, under the action of gravity and the impact force of the water body, the mutually entangled shrimp whiskers will be untied with the help of the water film or broken under the impact force, thereby forming a non-entangled bait shrimp monomer, thereby ensuring the speed and effect of subsequent classification; in addition, through the setting of the first dispersing fin and the second dispersing fin, the water body can be guided, and the guided water flow will impact the bait shrimp. First, it can ensure that the bait shrimp can pass quickly, and second, through the impact of the water body, it can ensure that the bait shrimp can be evenly dispersed at the first dispersing fin and the second dispersing fin, thereby preventing the occurrence of clustering, thereby preventing a large number of shrimp from dying due to lack of oxygen or overheating.

[0023] Furthermore, a first channel is arranged between a plurality of symmetrically arranged second dispersing fins, and a lower end portion of each first dispersing fin is arranged corresponding to an adjacent first channel.

[0024] Furthermore, a spraying member is provided on the upper side of the receiving surface. Through the provision of the spraying member, a uniform water film can be ensured on the receiving surface and the shrimp body, and at the same time, the temperature of the bait shrimp can be reduced to prevent the quality of the bait shrimp from being reduced during the classification process.

[0025] Furthermore, the plurality of first dispersing fins and the plurality of second dispersing fins are arranged perpendicular to the receiving surface. The plurality of first dispersing fins and the second dispersing fins arranged perpendicularly can better buffer the raw materials (such as bait shrimps) and the water body when receiving the raw materials transported by the separation conveyor, and can prevent the raw materials from slipping or being unable to be completely dispersed in the case of an inclined arrangement, thereby preventing the effective classification process.

[0026] Furthermore, the surfaces of the first dispersing fin and the second dispersing fin are smoothed and hydrophobic. Through the above treatment, when the shrimp and the water are transferred to the dispersing plate by the separation conveyor, the shrimp whiskers can be prevented from being entangled on the first dispersing fin and the second dispersing fin. At the same time, the hydrophobic treatment can prevent the water from staying on the first dispersing fin and the second dispersing fin, and can prevent bacteria and other microorganisms from breeding in the first dispersing fin or the second dispersing fin, thereby preventing the raw materials from being contaminated. Furthermore, the receiving surface, the first dispersing fin and the second dispersing fin are provided with antibacterial materials.

[0027] Furthermore, a plurality of first fixing columns are arranged horizontally at intervals on the upper layer of the receiving surface, and the first fixing columns are used to fix the top of the first dispersing fins, and a limiting column is arranged near the lower end of the first dispersing fins on the receiving surface. The first fixing column is arranged to fix the top of the first dispersing fins, so that the stability of the first dispersing fins can be effectively guaranteed. At the same time, a limiting column is arranged near the lower end of the first dispersing fins, that is, the first dispersing fins are fixed on one side at the top, and the lower side is arranged to float. The movement of the first dispersing fins is limited by the limiting column. When raw materials slide from the receiving surface to the first dispersing fins, the first dispersing fins will swing and bend, and part of the impact force will be absorbed by the swinging and bending, so as to prevent the shrimps from being subjected to excessive impact and causing death; in addition, the setting of the limiting column can prevent the first dispersing fins from bending or deforming when subjected to a large impact, and at the same time, it can prevent the first dispersing fins from bending too much at an angle and being unable to be opposite to the first channel.

[0028] According to an embodiment of the present invention, two second dispersing fins are arranged opposite to each other and tilted toward both sides. A buffer component is arranged between the two second dispersing fins. The buffer component includes a buffer base. The buffer base is arc-shaped. Both sides of the buffer base abut against the second dispersing fins.

[0029] Through the setting of the buffer component, when the bait shrimp and water move downward on the receiving surface, they will impact the second dispersing fin after passing through the first dispersing fin. The buffer matrix is ​​arc-shaped, and both sides abut the second dispersing fin. When the second dispersing fin generates an impact, the buffer matrix will deform to absorb energy, thereby preventing the second dispersing fin from bending or deforming when subjected to a large impact.

[0030] According to an embodiment of the present invention, small wing plates are symmetrically provided on both sides of the buffer base close to the second dispersing fins. The small wing plates are tilted outwards, and the ends of the small wing plates abut against the second dispersing fins.

[0031] Through the above design, the end of the small wing plate abuts against the second dispersion fin. When the second dispersion fin is impacted, the impact force will be transmitted to the small wing plate, and the small wing plate will preferentially absorb and resolve the impact force. Through the joint action of the large wing plate and the small wing plate, the impact of the shrimp on the second dispersion fin during the falling process is absorbed, reducing the stress response of the shrimp. When the impact of the water flow or the shrimp is small, the small wing plate is used to ensure the absorption of the impact through the fluctuation and vibration. When a large number of shrimps flow through or large shrimps fall, the large wing plate can ensure the stability and state of the overall device.

[0032] Furthermore, an elastic membrane is provided between the two sides of the buffer matrix and the two second dispersing fins. By providing the elastic membrane, a pulling force can be formed between the two second dispersing fins on both sides of the buffer matrix, and a tight fit can be formed between the second dispersing fins and the buffer matrix, that is, the second dispersing fins and the small wing plates are always in abutment under the action of the elastic membrane, preventing the second dispersing fins and the small wing plates from generating gaps or spaces, thereby preventing the second dispersing fins and the small wing plates from colliding under the impact of water or bait shrimps, thereby causing point contact between the second dispersing fins and the small wing plates to form damage; in addition, through the design of the elastic membrane, the air or airflow between two adjacent second dispersing fins can not flow out or flow in from both sides of the second dispersing fins, and by providing a small wing plate on one side of the buffer matrix, a gap will be left between the second dispersing fins and the buffer matrix, and the two adjacent second dispersing fins The internal air can only enter and exit from the gaps, that is, when the bait shrimp impacts the second dispersion fins, the two adjacent second dispersion fins will move relative to each other, squeezing the space inside them. Since the air can only enter and exit from the gaps between the second dispersion fins and the buffer matrix, it takes a certain amount of time for the air to enter and exit, which will then form a buffer for the second dispersion fins. At the same time, after the second dispersion fins are impacted, they will return to their original state. In this process, the setting of the elastic membrane can reduce the speed at which the second dispersion fins return to their original state, preventing the second dispersion fins from vibrating due to excessive recovery after a large impact. It can also improve the circulation of internal air, prevent residual bacteria or other microorganisms from parasitizing or breeding inside, and ensure the cleanliness of the entire device during operation.

[0033] Furthermore, holes are provided on the buffer substrate, and the air inside the adjacent second dispersion fins can also flow in and out through the holes, and the flow rate of the air in and out can be adjusted by adjusting the number of holes or the diameter of the holes.

[0034] According to an embodiment of the present invention, a buffer tube is provided at the connection between the winglet plate and the buffer base.

[0035] By setting the buffer tube, the impact absorption of the winglet can be improved. At the same time, the diameter or wall thickness of the buffer tube can be adjusted. By adjusting the buffer tube, the impact amount of the winglet and the angle of the winglet opening can be adjusted. The size of the buffer tube can be adjusted according to the size of different shrimps or shrimps at different times.

[0036] According to an embodiment of the present invention, the grading assembly includes a second conveyor belt, on which a plurality of grading rollers are arranged at intervals, the axes of the plurality of grading rollers are at a certain angle to the moving direction of the second conveyor belt, and the spacing between the plurality of grading rollers and the conveyor belt gradually decreases along the moving direction of the conveyor belt;

[0037] Both ends of the grading roller are connected to the second conveyor belt through adjustment components.

[0038] After the bait shrimp passes through the grading component, the bait shrimp will be evenly dispersed on the second conveyor belt, and through the multiple grading rollers arranged at intervals on the second conveyor belt, the multiple grading rollers gradually decrease in the direction of the conveyor belt movement. By controlling the spacing, the bait shrimps of different sizes will be separated under the action of multiple grading rods; while being separated, they will gradually move sideways under the action of the grading rollers, and the axis of the grading rollers is at a certain angle to the direction of the second conveyor belt movement, which can better realize the movement of the bait shrimp along the grading rollers until they are received. Adjustment components are set at both ends of the grading rollers, and the height of the grading rollers can be freely set through the adjustment components, that is, the grading rollers can be adjusted for different bait shrimps; in addition, the grading rollers can not only grade the bait shrimps, but also clean the surface of the bait shrimps to a certain extent.

[0039] Furthermore, guide ribs are provided at both ends of the second conveyor belt. The guide ribs can limit the flow range of the water flow, prevent the water flow from flowing out from both sides during the flow on the second conveyor belt, and further prevent the bait shrimp from falling from both sides of the second conveyor belt during the movement with the water body.

[0040] Furthermore, the width of the second conveyor belt is wider than that of the first conveyor belt, and the width of the dispersion substrate is between the widths of the second conveyor belt and the first conveyor belt. When the bait shrimp passes through the first conveyor belt, it will fall from the top of the first conveyor belt to the dispersion substrate. In this process, the dispersion of the bait shrimp will increase. By setting the dispersion substrate wider than the first conveyor belt, it can be prevented that the bait shrimp will slide out from the two sides of the dispersion substrate after falling. The second conveyor belt is wider than the dispersion substrate, which is also the same, so as to prevent the bait shrimp falling from the dispersion substrate from falling to the two sides of the second conveyor belt.

[0041] According to an embodiment of the present invention, the grading roller includes a first base body, the first base body includes holding members arranged opposite to each other, the holding members on one side are connected to the motor, and the holding members opposite to each other are connected by a plurality of rotating plates, and the rotating plates are spiral-shaped;

[0042] The second base is arranged around the outer side of the first base, and protrusions are rotatably arranged on the second base, and the protrusions gradually become sparse from both sides to the middle of the second base.

[0043] Through the above design, multiple rotating plates can be fixed by the retaining members, and the arrangement of multiple rotating plates can greatly reduce the weight of the grading roller. While the weight is reduced, multiple rotating plates can evenly distribute the weight and external force of the grading roller during the rotation and grading process, so that the overall device is strong, and the horizontality of the grading roller can be maintained to prevent bending during the rotation process, which is beneficial to the accuracy of grading; in addition, through the arrangement of the second base body and the arrangement of multiple protrusions, the entanglement between the grading roller and the bait shrimp can be reduced compared to the arrangement of bristles on the surface, and the grading efficiency can be improved, while avoiding the entanglement of too many shrimp whiskers on the grading roller, resulting in a decrease in screening capacity. In addition, the protrusions can reduce the damage to shrimps and improve the survival rate and activity of shrimps after screening. In addition, the protrusions can guide and absorb water. During the rotation of the grading roller, part of the water in the grading roller will be thrown out and the humidity around the device will be increased and the temperature will be reduced, which can reduce the stress response of shrimps and is beneficial to the classification, transportation and preservation of shrimps. At the same time, it is beneficial for oxygen in the air to enter the grading roller and increase the oxygen in the water flow guided by the grading roller. The water on the grading roller will be exchanged with the water on the conveyor belt during the rotation, so that the water on the conveyor belt contains higher oxygen and improves the survival rate of shrimps.

[0044] Furthermore, the rotating plate and the retaining member are connected by a plug-in connection, which can be better assembled, unassembled and maintained.

[0045] According to an embodiment of the present invention, the adjustment component includes an adjustment base, a rotating base is arranged on the adjustment base at intervals, the rotating base and the adjustment base are connected through the adjustment component, and the adjustment component is used to change the distance between the rotating base and the adjustment base;

[0046] The rotating base body is connected to the retaining member, and the adjusting base body is arranged on both sides of the second conveyor belt.

[0047] Through the above design, the rotating base is rotatably connected to the retaining member, and the retaining member in the rotating base rotates during operation. The adjustment component is used to change the distance between the rotating base and the adjustment base, thereby adjusting the distance between the grading roller and the second transmission belt.

[0048] According to one embodiment of the present invention, the adjustment component includes a rotating rod, and a first blind hole and a second blind hole are correspondingly arranged on the opposite sides of the rotating base and the adjusting base. The first blind hole and the second blind hole are used to set the rotating rod, and the rotating rod is rotatably set with a stabilizing foot at the lower side end of the second blind hole. A rotating connecting piece is arranged at the opening of the first blind hole, and the rotating connecting piece is used to be rotatably connected to the rotating rod. A third blind hole is arranged at one end of the rotating rod located in the second blind hole, and a spring is arranged in the third blind hole, and the spring abuts against the bottom of the third blind hole; a notch is arranged on one side of the rotating connecting piece, and a brake piece is arranged in the notch, and the brake piece is used to limit the rotation of the rotating rod.

[0049] Through the above design, a rotating rod is set through the first blind hole and the second blind hole, the stable angle can abut against the bottom side of the second blind hole, and the rotating connecting member is rotatably connected to the rotating rod. During the rotation of the rotating connecting member and the rotating rod, the rotating rod will move upward or downward relative to the rotating connecting member, thereby changing the distance between the rotating base and the adjusting base, thereby adjusting the distance between the grading roller and the second transmission belt.

[0050] By providing a third blind hole and a spring in the third blind hole, the spring can reduce the vibration generated by the rotating base when the retaining member in the rotating base rotates, and the vibration affects its height accuracy.

[0051] By providing a notch on one side of the rotating connecting member and arranging a brake in the notch, the rotation of the rotating rod is limited by the brake. During the operation of the entire device, the brake can prevent the rotating rod from loosening and rotating under vibration or other circumstances, thereby improving the classification accuracy.

[0052] Furthermore, a plurality of rotating beads are provided at the connection between the rotating connector and the rotating rod. By providing a plurality of rotating beads at the connection between the rotating connector and the rotating rod, during the rotation of the rotating rod, the rotating beads can better disperse the load, improve the smoothness and precision of the sliding, and reduce the vibration of the rotating connector and the rotating rod during the rotation process; at the same time, the damping is improved by providing a plurality of rotating beads, and after the rotation stops, the rotating beads can be in contact with the rotating rod under the action of gravity, and the plurality of rotating beads can be in contact with each other, so that stability can be achieved.

[0053] Furthermore, stabilizing rods are arranged at intervals on both sides of the rotating rod. One end of the stabilizing rod of the adjusting assembly is fixedly connected to the adjusting base, and a fourth blind hole is arranged at the corresponding position of the stabilizing base of the adjusting assembly and the stabilizing rod, and a stabilizing ring is arranged in the fourth blind hole, and the stabilizing ring is used to cooperate with the stabilizing rod. By providing the stabilizing rod, it is further improved that the stabilizing base and the adjusting base do not rotate relative to each other during the adjustment process and the operation process, thereby improving the stability of the overall device.

[0067] like Figure 1 , 2As shown in Figures 3, 4 and 5, a device for quickly and efficiently grading bait shrimps for breeding of needleless squid fry comprises a feeding component 1 and a separation component 2, and is characterized in that the feeding component 1 comprises a partitioning conveyor 11, the partitioning conveyor 11 is used to convey the raw materials into the separation component 2, a feeding box 12 is provided on one side of the partitioning conveyor 11, the feeding box 12 is used to input the raw materials into the partitioning conveyor 11, and the separation component 2 is used to grade the raw materials.

[0068] Through the above design, the raw material, i.e., the bait shrimp, is transported to the separation component 2 through the feeding group, and then the bait shrimp is graded through the separation component 2, and the graded bait shrimp is transferred to different storage boxes or other containers. Through the design of the feeding component 1, the bait shrimp is first transferred to the partition conveyor 11 through the feeding box 12, and the feeding box 12 is connected to a feeding pipe, and the raw material bait shrimp is transported to the feeding box 12 through the feeding pipe. At the same time, a discharge port is opened on the side of the feeding box 12 close to the partition conveyor 11, and the discharge port is connected to a guide plate, which guides the raw material coming out of the discharge port to the partition conveyor. The design of the feeding pipe can make it easier to feed the raw material into the feeding box 12, and at the same time, it can liberate more human resources. There are many ways to connect the feeding pipe to the feeding box 12. Furthermore, the feed pipe is connected to the bottom of the feed box 12, and the feed pipe inputs the raw materials from the bottom of the feed box 12. At the same time, a screw conveyor is provided in the feed box 12. The screw conveyor can push the raw materials at the bottom upward to the vicinity of the feed port through its own rotation, and convey the raw materials to the partition conveyor 11 through the discharge port. Through the setting of the screw conveyor, the power and start-stop interval of the screw conveyor can be adjusted according to demand, which is beneficial to improving the efficiency of the overall device and reducing energy consumption or waste.

[0069] Furthermore, the separation conveyor 11 includes a first conveyor belt, on which a plurality of separation plates or separation boxes are arranged at intervals. Through the above design, the separation plates and the separation boxes can both transport raw materials, and the separation plates and the separation boxes can separate the materials, i.e., the bait shrimps, into a plurality of groups for transportation, which can prevent the bait shrimps from sliding off the first conveyor belt due to the small friction between the surface of the bait shrimps and the first conveyor belt under the action of gravity and water; in addition, after the materials are grouped by the separation plates and the separation boxes, the quantity or weight of the materials in each group can be adjusted according to the speed of subsequent grading, thereby controlling the speed of the screw conveyor and the first conveyor belt.

[0070] Furthermore, when a partition plate is used, the partition conveyor plate can be tilted upward, that is, the raw materials are transported from a low point to a high point, and part of the water together with the raw materials can flow downward along the first conveyor belt under the action of gravity, thereby reducing the overall weight of the transportation, reducing the energy consumption of the transportation, and reducing the cost of transportation. Moreover, when the water body flows to the next partition plate layer by layer under the action of gravity, when the overall partition conveyor 11 is in operation, water will flow between each partition plate. During the flow of water, the water body can fully contact with the air after impacting the partition plate, thereby ensuring the oxygen content in the water body, thereby ensuring the survival rate of the bait shrimp during transportation on the first conveyor belt; in addition, when the water body impacts or collides with each partition plate during the flow, water vapor and fine water droplets will be generated, which can ensure the surrounding air The humidity of the air can be increased and the direct light can be scattered to prevent the stress reaction of the bait shrimps when encountering strong light during transportation. At the same time, the humid air can improve the adaptability of the shrimps and prevent the stress reaction of the shrimps after direct contact with the air, thereby preventing the bait shrimps from jumping out of the transportation range of the partition board due to stress reaction. At the same time, the flow and evaporation of the water body can reduce the temperature of the partition conveyor 11 and the surrounding area. When the temperature is lowered, the activity intensity of the shrimps can be reduced, the shrimps' perception of the outside world can be reduced, and the stress reaction of the shrimps can be reduced. The partition conveyor 11 can also be cooled to ensure that the temperature of the sealing motor on one side of the partition conveyor 11 is maintained within a reasonable range. At the same time, water vapor can absorb sound waves, which can reduce the noise interference of the staff when working for a long time.

[0071] Furthermore, when a partition box is used, the separation box can prevent shrimps from jumping out. At the same time, the separation box can effectively preserve the water body compared to the partition plate. When the number of bait shrimps is large, the survival rate of the shrimps can be improved. In addition, by setting up a partition box, the first conveyor belt of the partition conveyor 11 does not need to be placed at an angle, and can be placed horizontally or tilted downward, thereby improving the flexibility of the placement and state of the device. Furthermore, the bottom layer or middle layer of the separation box is provided with fine holes, through which water can flow out. The fineness of the hole setting and the diameter of the hole are related to the length and speed of the first conveyor belt. When the raw materials enter the separation box through the feeding box 12, the remaining water in the separation box needs to ensure that the shrimps will not die during the process from the feeding point to the unloading point of the separation box. At the same time, the small holes can guide the water to flow out. After the water flows out, the water will flow down along the wall of the separation box. In this process, the surface area of ​​the water increases, which improves the evaporation efficiency and effect, and can reduce the temperature of the separation box to prevent the temperature in the box from rising when there are more shrimps, thereby preventing the shrimps from having a stress response or dying from lack of oxygen.

[0072] Furthermore, when a partition plate is used, the speed of the screw conveyor can be uniformly controlled to ensure that the amount of raw materials, i.e., bait shrimps, between each partition plate is the same; when a partition box is used, the screw conveyor belt can be started and stopped at intervals to prevent the raw materials, i.e., bait shrimps, from spilling outside the partition box, and the start and stop intervals can be controlled to ensure that the amount of raw materials, i.e., bait shrimps, in each partition box is the same or similar. This arrangement can reduce overall power consumption and improve energy utilization.

[0073] The separation component 2 includes a dispersion component 21 and a classification component 22. The dispersion component 21 is used to disperse the raw materials transported by the separation conveyor 11, and the classification component 22 is used to classify the dispersed raw materials.

[0074] After the raw materials are dispersed by the dispersing component 21, the dispersed raw materials can ensure their uniformity, and in the subsequent process of grading the raw materials, the efficiency and success rate of the grading process are improved.

[0075] Furthermore, a plurality of receiving components are provided on one side of the grading component 22. The graded raw materials are received by the plurality of receiving components respectively to prevent the graded raw materials from piling up or mixing. The receiving components may be storage boxes or other containers.

[0076] The dispersion component 21 includes a dispersion substrate 23, which is arranged at the bottom of the separation conveyor 11 near the separation component 2, and the dispersion substrate 23 is inclined toward the classification component 22. The dispersion substrate 23 receives the raw materials transported by the separation conveyor 11 through the receiving surface 231, and a plurality of first dispersion fins 24 are arranged in the middle layer of the receiving surface 231, and the plurality of first dispersion fins 24 are symmetrically inclined along the central axis of the receiving surface 231.

[0077] A plurality of symmetrically arranged second dispersing fins 25 are provided on the lower side of the receiving surface 231 .

[0078] Through the above design, the receiving surface 231 of the dispersed substrate 23 is used to receive the raw materials transported by the partition conveyor 11, and a plurality of first dispersed fins 24 are arranged in the middle layer of the receiving surface 231, and a plurality of symmetrically arranged second dispersed fins 25 are arranged on the lower side, so that the receiving surface 231 can be divided into three parts. The upper layer of the receiving surface 231 is used to receive the raw materials. The surface of the receiving surface 231 is smooth. When the raw materials are transferred from the partition conveyor 11, the bait shrimp and the water body are received by the receiving surface 231 together. The upper side of the receiving surface 231 is conducive to the downward movement of each component under the action of gravity. The first dispersing fins 24 are arranged to buffer and disperse the raw materials moved from the upper layer of the receiving surface 231. The multiple first dispersing fins 24 are arranged symmetrically and tilted to both sides along the central axis of the receiving surface 231, which can disperse the raw materials and make the raw materials move downward under the action of gravity. The second dispersing fins 25 are used to further disperse and buffer the raw materials from the first dispersing fins 24. The second dispersing fins 25 arranged relatively are arranged in an inverted V shape, which further disperses the raw materials to the entire second conveyor belt 221, thereby improving the efficiency of grading in the grading component 22 and preventing grading errors. The multi-stage dispersing substrate 23 can prevent the shrimps from being unable to be separated or classified correctly due to the entanglement of whiskers between the shrimps. The smooth setting of the receiving surface 231 is conducive to the downward sliding of the bait shrimp. At the same time, a smooth water film can be formed on the surface after contacting the water body. The friction between the bait shrimp and the receiving surface 231 can be further reduced by the setting of the water film. In addition, a water film can also be formed on the surface of the bait shrimp. The friction between the shrimp bodies or between the shrimp whiskers can be reduced by the water film to prevent the shrimp whiskers from being entangled. At the same time, when the bait shrimp passes through the first dispersing fins 24 and the second dispersing fins 25, under the action of gravity and the impact force of the water body, the mutually entangled shrimp whiskers will be swayed by the water film. The first dispersing fins 24 and the second dispersing fins 25 can be used to guide the water body, and the guided water flow can impact the bait shrimps, which can ensure that the bait shrimps can pass quickly, and can ensure that the bait shrimps can be evenly dispersed at the first dispersing fins 24 and the second dispersing fins 25 through the impact of the water body, thereby preventing the bait shrimps from clumping and thus preventing a large number of shrimps from dying due to lack of oxygen or overheating.

[0079] Furthermore, a first channel is disposed between a plurality of symmetrically disposed second dispersing fins 25 , and a lower end portion of each first dispersing fin 24 is disposed corresponding to an adjacent first channel.

[0080] Furthermore, a spraying member is provided on the upper side of the receiving surface 231. The provision of the spraying member can ensure a uniform water film on the receiving surface 231 and the shrimp body, and at the same time can reduce the temperature of the bait shrimp to prevent the quality of the bait shrimp from being reduced during the classification process.

[0081] Furthermore, a plurality of first dispersing fins 24 and a plurality of second dispersing fins 25 are arranged perpendicular to the receiving surface 231. The plurality of first dispersing fins 24 and second dispersing fins 25 arranged perpendicularly can better buffer the raw materials such as bait shrimp and water when receiving the raw materials transported by the separation conveyor 11, and can prevent the raw materials from slipping or being unable to be thoroughly dispersed in the case of an inclined arrangement, thereby preventing the effective classification process.

[0082] Furthermore, the surfaces of the first dispersing fin 24 and the second dispersing fin 25 are smoothed and hydrophobic. Through the above treatment, when the shrimp and the water are transferred to the dispersing plate by the separation conveyor 11, the shrimp whiskers can be prevented from being entangled on the first dispersing fin 24 and the second dispersing fin 25, and the hydrophobic treatment can prevent the water from staying on the first dispersing fin 24 and the second dispersing fin 25, and can prevent bacteria and other microorganisms from breeding in the first dispersing fin 24 or the second dispersing fin 25, thereby preventing the raw materials from being contaminated. Furthermore, the surfaces of the receiving surface 231, the first dispersing fin 24 and the second dispersing fin 25 are provided with antibacterial materials.

[0083] Furthermore, a plurality of first fixing columns are arranged horizontally at intervals on the upper layer of the receiving surface 231, and the first fixing columns are used to fix the top of the first dispersing fin 24. A limiting column is arranged near the lower end of the first dispersing fin 24 on the receiving surface 231. The stability of the first dispersing fin 24 can be effectively guaranteed by fixing the top of the first dispersing fin 24 with the first fixing column. At the same time, a limiting column is arranged near the lower end of the first dispersing fin 24, that is, the first dispersing fin 24 is fixed on one side at the top, and the lower side is floatingly arranged. The movement of the first dispersing fin 24 is limited by the limiting column. When raw materials slide from the receiving surface 231 to the first dispersing fin 24, the first dispersing fin 24 will swing and bend, and part of the impact force will be absorbed by the swinging and bending, so as to prevent the shrimp from being subjected to excessive impact and causing death. In addition, the setting of the limiting column can prevent the first dispersing fin 24 from bending or deforming when subjected to a large impact, and can also prevent the first dispersing fin 24 from bending too much at an angle to be opposite to the first channel.

[0084] The two second dispersing fins 25 opposite to each other are inclined to both sides. A buffer assembly 26 is provided between the two second dispersing fins 25 opposite to each other. The buffer assembly 26 includes a buffer base 261 . The buffer base 261 is arc-shaped. Both sides of the buffer base 261 abut against the second dispersing fins 25 .

[0085] Through the setting of the buffer component 26, when the bait shrimp and water move downward on the receiving surface 231, they will impact the second dispersing fin 25 after passing through the first dispersing fin 24. The buffer base 261 is arc-shaped, and the two sides abut the second dispersing fin 25. When the second dispersing fin 25 generates an impact, the buffer base 261 will deform to absorb energy, thereby preventing the second dispersing fin 25 from bending or deforming when subjected to a large impact.

[0086] Small wing plates 262 are symmetrically provided on both sides of the buffer base 261 close to the second dispersing fins 25 . The small wing plates 262 are tilted outwards, and the ends of the small wing plates 262 abut against the second dispersing fins 25 .

[0087] Through the above design, the end of the small wing plate 262 abuts against the second dispersion fin 25. When the second dispersion fin 25 is impacted, the impact force will be transmitted to the small wing plate 262, and the small wing plate 262 will preferentially absorb and resolve the impact force. Through the joint action of the large wing plate and the small wing plate 262, the impact of the shrimp on the second dispersion fin 25 during the falling process is absorbed, reducing the stress response of the shrimp. When the impact of the water flow or the shrimp is small, the small wing plate 262 is used to ensure the absorption of the impact through the fluctuation and vibration. When a large number of shrimps flow through or large shrimps fall, the large wing plate can ensure the stability and state of the overall device.

[0088] Furthermore, an elastic membrane is provided between the two sides of the buffer substrate 261 and the two second dispersion fins 25. By providing the elastic membrane, a pulling force can be formed between the two second dispersion fins 25 on both sides of the buffer substrate 261, and a tight fit can be formed between the second dispersion fins 25 and the buffer substrate 261, that is, the second dispersion fins 25 and the small wing plate 262 are always in abutment under the action of the elastic membrane, preventing the second dispersion fins 25 and the small wing plate 262 from generating gaps or spaces, thereby preventing the second dispersion fins 25 and the small wing plate 262 from colliding under the impact of water or bait shrimp, thereby causing point contact between the second dispersion fins 25 and the small wing plate 262 to form damage; in addition, by designing the elastic membrane, the air or airflow between two adjacent second dispersion fins 25 cannot flow out or flow in from both sides of the second dispersion fins 25, and by providing the small wing plate 262 on one side of the buffer substrate 261, a gap will be left between the second dispersion fins 25 and the buffer substrate 261. , the air inside the two adjacent second dispersing fins 25 can only enter and exit from the gaps, that is, when the bait shrimp is impacted on the second dispersing fins 25, the two adjacent second dispersing fins 25 will move relative to each other, squeezing the space inside them. Since the air can only enter and exit from the gaps left between the second dispersing fins 25 and the buffer matrix 261, it takes a certain amount of time for the air to enter and exit, thereby forming a buffer for the second dispersing fins 25; at the same time, after the second dispersing fins 25 are impacted, they will return to their original state. In this process, the setting of the elastic membrane can reduce the speed at which the second dispersing fins 25 return to their original state, preventing the second dispersing fins 25 from vibrating due to a too fast recovery after a large impact, and can also improve the circulation of the internal air, preventing the remaining bacteria or other microorganisms from parasitizing or breeding inside, thereby ensuring the cleanliness of the entire device during operation.

[0089] Furthermore, holes are provided on the buffer substrate 261. The air inside the adjacent second dispersion fins 25 can also flow in and out through the holes, and the flow rate of the air in and out can be adjusted by adjusting the number of holes or the diameter of the holes.

[0090] A buffer tube 263 is provided at the connection between the winglet plate 262 and the buffer base 261 .

[0091] The buffer tube 263 can be provided to improve the impact absorption of the winglet 262. The diameter or wall thickness of the buffer tube 263 can be adjusted. The impact of the winglet 262 and the angle of the winglet 262 can be adjusted by adjusting the buffer tube 263. The size of the buffer tube 263 can be adjusted according to the size of different shrimps or shrimps at different times.

[0092] Embodiment 2:

[0093] like Figure 1 , 2 , 6, 7, 8, 9, and 10 schematically show a fast and efficient grading device for bait shrimp for breeding of needleless squid according to another embodiment of the present invention, which is different from Example 1 in that:

[0094] The grading assembly 22 includes a second conveyor belt 221, on which a plurality of grading rollers 27 are arranged at intervals, the axes of the plurality of grading rollers 27 are at a certain angle to the moving direction of the second conveyor belt 221, and the spacing between the plurality of grading rollers 27 and the conveyor belt gradually decreases along the moving direction of the conveyor belt;

[0095] Both ends of the grading roller 27 are connected to the second conveyor belt 221 through an adjustment assembly 28 .

[0096] After the bait shrimp passes through the grading assembly 22, the bait shrimp will be evenly dispersed on the second conveyor belt 221, and through the multiple grading rollers 27 arranged at intervals on the second conveyor belt 221, the multiple grading rollers 27 gradually decrease in the direction of the conveyor belt movement. By controlling the spacing, the bait shrimps of different sizes will be separated under the action of multiple grading rollers; while being separated, they will gradually move sideways under the action of the grading rollers 27, and the axis of the grading rollers 27 and the direction of the second conveyor belt 221 are at a certain angle, which can better realize the movement of the bait shrimp along the grading rollers 27 until they are in the receiving assembly. Then, the grading rollers 27 are provided with adjustment assemblies 28 at both ends, and the height of the grading rollers 27 can be freely set by the adjustment assemblies 28, that is, the grading rollers 27 can be adjusted according to different bait shrimps; in addition, the grading rollers 27 can not only grade the bait shrimps, but also clean the surface of the bait shrimps to a certain extent.

[0097] Furthermore, guide ribs are provided at both ends of the second conveyor belt 221. The guide ribs can limit the flow range of the water flow, prevent the water flow from flowing out from both sides during the flow on the second conveyor belt 221, and further prevent the bait shrimp from falling from both sides of the second conveyor belt during the movement with the water.

[0098] Furthermore, the width of the second conveyor belt 221 is wider than that of the first conveyor belt, and the width of the dispersion substrate 23 is between the widths of the second conveyor belt and the first conveyor belt. When the bait shrimp passes through the first conveyor belt, it will fall from the top of the first conveyor belt to the dispersion substrate 23. In this process, the dispersion of the bait shrimp will increase. By setting the dispersion substrate 23 wider than the first conveyor belt, it can be prevented that the bait shrimp will slide out from the two sides of the dispersion substrate 23 after falling. The second conveyor belt 221 is wider than the dispersion substrate 23, which is also the same, so as to prevent the bait shrimp falling from the dispersion substrate 23 from falling to the two sides of the second conveyor belt 221.

[0099] The grading roller 27 includes a first base body, the first base body includes holding members 271 arranged opposite to each other, the holding member 271 on one side is connected to a motor 272, and the holding members 271 opposite to each other are connected by a plurality of rotating plates 273, and the rotating plates 273 are spiral-shaped;

[0100] A motor 274 is disposed around the outer side of the first substrate, and protrusions 275 are rotatably disposed on the motor 274 . The protrusions 275 gradually become sparse from both sides to the middle of the motor 274 .

[0101] Through the above-mentioned design, the plurality of rotating plates 273 can be fixed by the retaining member 271. The setting of the plurality of rotating plates 273 can greatly reduce the weight of the grading roller 27. While the weight is reduced, the plurality of rotating plates 273 can evenly distribute the weight and external force of the grading roller 27 during the rotation and grading process, so that the overall device is strong, and the horizontality of the grading roller 27 can be maintained to prevent bending during the rotation process, which is beneficial to the accuracy of grading. In addition, through the setting of the motor 274 and the setting of the plurality of protrusions 275, the entanglement between the grading roller 27 and the bait shrimp can be reduced compared with the arrangement of bristles on the surface, so the grading efficiency can be improved, and at the same time, it can be avoided that too many shrimp whiskers are entangled on the grading roller 27 to cause The screening capacity is reduced; in addition, the setting of the protrusion 275 can reduce the damage to the shrimp, and improve the survival rate and activity of the shrimp after screening; in addition, the protrusion 275 can guide and absorb water. During the rotation of the grading roller 27, part of the water in the grading roller 27 will be thrown out and the humidity around the device will be increased and the temperature will be reduced, which can reduce the stress response of the shrimp, which is beneficial to the classification, transportation and preservation of the shrimp, and at the same time, it is beneficial for the oxygen in the air to enter the grading roller 27 and then increase the oxygen in the water flow guided by the grading roller 27. The water on the grading roller 27 will be exchanged with the water on the conveyor belt during the rotation, so that the water on the conveyor belt contains higher oxygen, thereby improving the survival rate of the shrimp.

[0102] Furthermore, the rotating plate 273 is plug-connected to the retaining member 271. The plug-connection allows for better assembly, disassembly and maintenance.

[0103] The adjustment assembly 28 includes an adjustment base 281, on which a rotating base 282 is spaced apart. The rotating base 282 and the adjustment base 281 are connected via an adjustment member 29, and the adjustment member 29 is used to change the distance between the rotating base 282 and the adjustment base 281.

[0104] The rotating base 282 rotates to connect the retaining member 271 , and the adjusting base 281 is disposed on both sides of the second conveyor belt 221 .

[0105] Through the above design, the rotating base 282 is rotatably connected to the retaining member 271, and the retaining member 271 in the rotating base 282 rotates during operation. The adjusting member 29 is used to change the distance between the rotating base 282 and the adjusting base 281, thereby adjusting the distance between the grading roller 27 and the second transmission belt.

[0106] The adjusting member 29 includes a rotating rod 291. A first blind hole 284 and a second blind hole 283 are correspondingly provided on the opposite side of the rotating base 282 and the adjusting base 281. The first blind hole 284 and the second blind hole 283 are used to set the rotating rod 291. The rotating rod 291 is rotatably provided with a stabilizing foot 292 at the lower side end of the second blind hole 283.

The rotating rod 291 is located in the second blind hole 283. One end thereof is provided with a third blind hole 293. A spring 294 is provided in the third blind hole 293. The spring 294 abuts against the bottom of the third blind hole 293, and the other end of the spring 294 abuts against the bottom of the first blind hole 284. A notch 286 is provided on one side of the rotating connecting member 285. A brake member 287 is provided in the notch 286. The brake member 287 is used to limit the rotation of the rotating rod 291.

[0107] Through the above design, the rotating rod 291 is set through the first blind hole 284 and the second blind hole 283, the stable angle can abut against the bottom side of the second blind hole 283, and the rotating connecting member 285 is rotatably connected to the rotating rod 291. During the rotation of the rotating connecting member 285 and the rotating rod 291, the rotating rod 291 will move upward or downward relative to the rotating connecting member 285, thereby changing the distance between the rotating base 282 and the adjusting base 281, thereby adjusting the distance between the grading roller 27 and the second transmission belt.

[0108] By providing a third blind hole 293 and a spring 294 in the third blind hole 293, the spring 294 can reduce the vibration of the rotating base 282 when the retaining member 271 rotates in the rotating base 282, which affects the height accuracy.

[0109] By providing a notch 286 on one side of the rotating connecting member 285 and arranging a brake member 287 in the notch 286, the brake member 287 limits the rotation of the rotating rod 291. During the operation of the entire device, the brake member 287 can prevent the rotating rod 291 from loosening and rotating under vibration or other conditions, thereby improving the grading accuracy.

[0110] Furthermore, a plurality of rotating beads are provided at the connection between the rotating connector 285 and the rotating rod 291. By providing a plurality of rotating beads at the connection between the rotating connector 285 and the rotating rod 291, during the rotation of the rotating rod 291, the rotating beads can better disperse the load, improve the smoothness and precision of the sliding, and reduce the vibration of the rotating connector 285 and the rotating rod 291 during the rotation process; at the same time, the damping is improved by providing a plurality of rotating beads, and after the rotation stops, the rotating beads can be in contact with the rotating rod 291 under the action of gravity, and the plurality of rotating beads can be in contact with each other, so that stability can be achieved.

[0111] Furthermore, stabilizing rods are arranged at intervals on both sides of the rotating rod 291.

By providing the stabilizing rod, it is further improved that the stabilizing base and the adjusting base 281 do not rotate relative to each other during the adjustment process and the operation process, thereby improving the stability of the overall device.
