Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a crayfish farming and catching device. Background Technology

[0002] Lobsters, with their delicious meat and rich nutrition, have seen a continuous increase in market demand and have become one of the important economic species in my country's aquaculture sector. With the maturation of aquaculture technology, lobster farming has gradually shifted from traditional small-scale, scattered farming to intensive, large-scale pond or cage farming, significantly increasing yields and density. This has placed higher demands on the adaptability, efficiency, and quality assurance of the harvesting process.

[0003] As a crucial final step in the crayfish farming cycle, the harvesting process directly impacts farming profits and product quality. Currently, traditional harvesting methods in crayfish farming primarily rely on hand nets or periodic water pumping. Manually operating hand nets requires repeated movement within the water, resulting in low overall efficiency and difficulty meeting the timeliness requirements of large-scale harvesting. Furthermore, the collision and friction between the nets and the crayfish's limbs can cause shell abrasion or appendage detachment in some crayfish. Additionally, the agitation of the water during harvesting can trigger stress in the crayfish, affecting their vitality and subsequent survival. Therefore, there is an urgent need to develop a crayfish farming harvesting device to address these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crayfish farming and catching device, which solves the technical problems of traditional crayfish catching, which mainly relies on hand nets or water pumping, resulting in low efficiency, easy damage to crayfish, and water agitation causing stress that affects their survival.

[0005] To achieve the above objectives, this utility model provides a crayfish farming and catching device through the following technical solution: a box for crayfish farming, a lid on the top of the box, and an auxiliary catching mechanism for catching crayfish inside the box.

[0006] The auxiliary capture mechanism includes a mesh plate located at the bottom of the box, a rubber strip fixed to the outer side of the top of the mesh plate and attached to the inner wall of the box, the rubber strip having a triangular cross-section, cables passing through the top of both sides of the top of the mesh plate, multiple sets of limiting rings for limiting the cables fixed to both sides of the front of the box, and a winding assembly for winding the cables fixed to the bottom of the front of the box.

[0007] Preferably, a mounting groove is provided at the center of the top of the cover, and a perforated metal plate is embedded in the mounting groove.

[0008] Preferably, the winding assembly includes a housing providing an installation location, two sets of winding rollers for winding the cable, a turntable for the operator to hold and rotate, and a linkage rod for synchronously rotating the two sets of winding rollers.

[0009] Preferably, the housing is fixed to the bottom of the front of the box, the winding rollers are rotatably installed on both sides inside the housing, one end of the winding roller is fixedly connected to a support rod that passes through one side of the housing, one end of the support rod is driven to install a turntable, and a linkage rod is fixedly connected between the two sets of winding rollers to drive the two sets of winding rollers to rotate synchronously.

[0010] Preferably, it also includes an auxiliary transfer assembly for transferring lobsters. The auxiliary transfer assembly includes a discharge port that is installed through the top of the front of the box. A connecting shaft frame is also provided at the top of the front of the box. A rotatable auxiliary discharge plate is installed on the inner side of the connecting shaft frame through a connector. The connecting shaft frame is located below the discharge port. An electric rod is also rotatably installed on the top of the front of the box through a hinge seat. A shaft is fixedly connected to the output end of the electric rod. The top end of the shaft is rotatably connected to the bottom of the auxiliary discharge plate.

[0011] Preferably, the mesh diameter of the mesh plate is 5-10mm, and the mesh plate is made of stainless steel.

[0012] This invention provides a crayfish farming and catching device. Compared with the prior art, it has the following advantages.

[0013] 1. The double winding rollers of the winding assembly are linked by a linkage rod, which can drive the cable to smoothly pull the net plate up along the inner wall of the box. With the triangular rubber strip on the outer side of the top of the net plate and the tight fit with the inner wall of the box, the net plate's porous structure can quickly separate the lobster from the water, avoiding the stress response of the lobster caused by the stirring of the water by traditional hand nets, reducing limb breakage and loss. It can also seal the gap between the net plate and the box, preventing small lobsters from slipping and being missed, thus solving the problems of low efficiency and poor integrity of traditional fishing.

[0014] 2. The electric rod of the auxiliary transfer component can drive the shaft to adjust the tilt angle of the auxiliary feeding plate with the connecting shaft frame as the axis, which can be adapted to collection containers of different heights. There is no need to move the container frequently. The lobster slides into the tilted auxiliary feeding plate through the feeding port. The inclined sliding conveyor replaces manual grabbing, which not only shortens the exposure time of the lobster out of the water and reduces oxygen loss, but also avoids shell wear and appendage loss caused by manual contact, thus solving the problems of low efficiency and high damage rate of commercial lobsters in traditional transfer.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] First implementation method:

[0025] refer to Figure 1-2 , Figure 5-7 A crayfish farming and catching device includes a box 1 for crayfish farming, a cover 101 on the top of the box 1, and an auxiliary catching mechanism 2 for catching crayfish inside the box 1.

[0026] The auxiliary capture mechanism 2 includes a mesh plate 204 disposed at the bottom of the inside of the housing 1. A rubber strip 205 is fixedly attached to the outer side of the top of the mesh plate 204 and the rubber strip 205 is in contact with the inner wall of the housing 1. The cross section of the rubber strip 205 is triangular. Cables 202 passing through the top of both sides of the top of the mesh plate 204 are fixedly attached to the top of the housing 1. Multiple sets of limiting rings 203 for limiting the cable 202 are fixedly attached to both sides of the front of the housing 1. A winding assembly 201 for winding the cable 202 is also fixedly attached to the bottom of the front of the housing 1.

[0027] A mounting groove is provided at the center of the top of the cover 101, and a perforated metal plate 102 is embedded in the mounting groove.

[0028] The winding assembly 201 includes a housing 2011 that provides an installation position, two sets of winding rollers 2012 for winding the cable 202, a turntable 2013 for an operator to hold and rotate, and a linkage rod 2014 for coordinating the synchronous rotation of the two sets of winding rollers 2012.

[0029] The housing 2011 is fixed to the bottom of the front of the box 1. The winding roller 2012 is rotatably installed on both sides inside the housing 2011. One end of the winding roller 2012 is fixedly connected to a support rod that passes through one side of the housing 2011. A turntable 2013 is installed on one end of the support rod. A linkage rod 2014 is fixedly connected between the two sets of winding rollers 2012 to drive the two sets of winding rollers 2012 to rotate synchronously.

[0030] The mesh diameter of the 204 mesh plate is 5-10mm, and the 204 mesh plate is made of stainless steel.

[0031] Working principle: The operator first opens the cover 101, places the crayfish seedlings, aquaculture water and an appropriate amount of aquatic plants inside the box 1, and then closes the cover 101 to complete the initial deployment. The metal perforated plate 102 installed in the groove at the top of the cover 101 can ensure air circulation inside and outside the box 1, and prevent the crayfish from dying due to lack of oxygen in the aquaculture water. On the other hand, the operator can put feed into the box 1 through the mesh of the metal perforated plate 102 without frequently opening the cover 101, reducing the interference with the crayfish farming environment and reducing the stress response of crayfish caused by environmental fluctuations.

[0032] When it is necessary to catch lobsters that have reached the catch size in the box 1, the operator holds the turntable 2013 and rotates it clockwise. The turntable 2013 drives the support rod fixed to it to rotate, which in turn drives the winding roller 2012 to rotate in the shell 2011. Since the two sets of winding rollers 2012 are fixedly connected by the linkage rod 2014, the linkage rod 2014 can ensure that the two sets of winding rollers 2012 rotate synchronously, avoiding uneven stress on the cable 202 due to excessive winding speed on one side, which could cause the net plate 204 to tilt and the lobsters to slip off.

[0033] During the rotation of the winding roller 2012, the cable 202 is wound up. Multiple sets of limiting rings 203 on both sides of the front of the box 1 can limit the movement trajectory of the cable 202, preventing the cable 202 from deviating from the preset path and rubbing against the edge of the box 1 during the winding process, causing wear. As the cable 202 is wound up, the cable 202 pulls the mesh plate 204 to move upward along the inner wall of the box 1.

[0034] When the net plate 204 moves upward, the aquaculture water in the box 1 can flow back to the bottom of the box 1 through the mesh, realizing the rapid separation of the crayfish from the water. This avoids the problems of water agitation and crayfish struggling to escape caused by manual net catching in traditional fishing methods. At the same time, the rubber strip 205 on the outer side of the top of the net plate 204 moves upward synchronously with the net plate 204. Since the rubber strip 205 has a triangular cross section and fits tightly against the inner wall of the box 1, it can seal the gap between the net plate 204 and the inner wall of the box 1, effectively preventing smaller crayfish from sliding down the gap to the bottom of the box 1. It also avoids mechanical damage caused by crayfish getting their limbs stuck in the gap during the capture process.

[0035] When the net plate 204 moves up to the top of the inside of the box 1 and reaches its maximum travel, all the lobsters will remain on the top of the net plate 204. Operators can directly collect the lobsters on the net plate 204 without having to repeatedly scoop them out of the water.

[0036] After the lobsters are collected, the operator rotates the turntable 2013 in the opposite direction, causing the winding roller 2012 to release the cable 202. The mesh plate 204 slowly slides down the inner wall of the box 1 and resets itself by the weight of its own stainless steel material.

[0037] This device achieves integrated aquaculture and capture, as well as non-destructive and efficient capture, through the combined design of mesh plate 204, synchronous winding assembly 201 and sealing rubber strip 205. Among them, the winding assembly 201 can ensure that the mesh plate 204 moves smoothly upward through synchronous winding action, preventing lobsters from slipping off due to the tilt of the mesh plate 204. The sealing rubber strip 205 can fit tightly against the inner wall of the box 1, sealing the gap between the mesh plate 204 and the box 1, preventing lobsters from escaping from the gap and preventing lobster limbs from getting stuck in the gap and causing damage.

[0038] The porous structure of the mesh 204 allows for rapid backflow of aquaculture water during its ascent, achieving efficient separation of crayfish from the water without disturbing the water inside the tank 1. This solves the problem that traditional crayfish catching methods often result in strong stress reactions from water disturbance, with some crayfish suffering limb breakage due to violent struggles, significantly reducing survival rates. In addition, traditional hand nets are inefficient, requiring repeated scooping in the water, which is not only time-consuming and laborious but also prone to missing smaller crayfish, affecting the integrity of the catch.

[0039] Second implementation method:

[0040] During the transfer process after lobster capture, manual handling is inefficient, the transfer time for each batch is long, and the batch capture in multiple containers can easily lead to subsequent batches of lobsters being exposed to the air for a long time, resulting in a decrease in the survival rate due to lack of oxygen. At the same time, when manual handling of lobsters is done with auxiliary tools, it can easily cause wear and tear on the lobster's shell and the loss of its appendages. Therefore, this device is also designed with an auxiliary transfer component, the structure and working principle of which are as follows.

[0041] refer to Figure 3-4In the second embodiment of this utility model, an auxiliary transfer component 3 for transferring lobsters is also included. The auxiliary transfer component 3 includes a discharge port 301 that is installed through the top of the front of the box body 1. A connecting shaft frame 302 is also provided on the top of the front of the box body 1. A rotatable auxiliary discharge plate 303 is installed on the inner side of the connecting shaft frame 302 through a connector. The connecting shaft frame 302 is located below the discharge port 301. An electric rod 304 is also rotatably installed on the top of the front of the box body 1 through a hinge seat. A shaft 305 is fixedly connected to the output end of the electric rod 304. The top end of the shaft 305 is rotatably connected to the bottom of the auxiliary discharge plate 303.

[0042] Working principle: After the lobster moves to the top of the box 1 on the mesh plate 204 and is separated from the water, the operator controls the output end of the electric rod 304 to extend and retract according to the height of the external collection container, such as a plastic turnover box or a transport water tank, through an external controller, thereby driving the shaft 305 to move vertically up and down.

[0043] Since the top of the shaft 305 is rotatably connected to the bottom of the auxiliary feeding plate 303, and the auxiliary feeding plate 303 is rotatably connected to the connecting shaft frame 302 through the connecting piece, the lifting and lowering of the shaft 305 will push the auxiliary feeding plate 303 to adjust the arc angle with the connecting shaft frame 302 as the rotation axis. When the output end of the electric rod 304 extends, the shaft 305 is pushed up, and the auxiliary feeding plate 303 tilts away from the box 1. When the output end of the electric rod 304 retracts, the shaft 305 is pulled down, and the auxiliary feeding plate 303 resets towards the box 1, thus realizing the adaptation to collection containers of different heights.

[0044] After adjustment, the operator uses a soft brush to drive the lobsters on top of the net plate 204. Under the driving force, the lobsters slide down through the feeding port 301 on the top front of the box 1 onto the auxiliary feeding plate 303. Through the auxiliary feeding plate 303, which is at a preset tilt angle, the lobsters can slide smoothly down the slope of the auxiliary feeding plate 303 into the collection container below. The whole process does not require direct manual contact with the lobsters, avoiding mechanical damage during handling. The angle of the auxiliary feeding plate 303 can be adjusted to adapt to collection containers of different heights, eliminating the need for frequent container movement. At the same time, the lobsters are slid down the slope instead of being manually handled, avoiding direct mechanical contact and shortening the exposure time of the lobsters after leaving the water. This design effectively solves the technical problems of low transfer efficiency, high damage, and large loss of commercial value, and is especially suitable for large-scale lobster farming scenarios.
