Technical Field
[0001] This invention relates to the field of aquaculture equipment technology, specifically to a snail farming equipment based on a three-dimensional expansion structure. Background Technology
[0002] As an aquatic animal with both edible and ecological value, snails have seen a surge in market demand in recent years due to the rise of related downstream industries, making large-scale artificial breeding an inevitable trend in the industry's development. Currently, snail breeding equipment is mainly divided into two categories: planar breeding devices and simple multi-layer breeding devices. Planar breeding devices can only utilize the surface or bottom space of the water body, resulting in low breeding density and limited yield per unit area, making it difficult to meet the needs of large-scale breeding. While simple multi-layer breeding devices attempt to achieve three-dimensional breeding, they suffer from fixed structures and poor flexibility in expansion. They cannot adjust the breeding space according to changes in the snail's growth cycle and breeding scale. Furthermore, the multi-layer structure is prone to problems such as poor water flow, uneven dissolved oxygen levels, and uneven feed distribution, leading to inconsistent snail growth rates and sizes. In addition, snails are difficult to catch during the breeding process, and juvenile snails are easily mixed with adult snails, affecting breeding efficiency.
[0003] In existing technologies, some multi-layer aquaculture equipment attempts to build multi-layer aquaculture structures using fixed supports, but this cannot achieve flexible expansion, and the fixed spacing between layers cannot adapt to the spatial needs of snails at different growth stages. Some adjustable multi-layer aquaculture equipment has a cumbersome adjustment process and lacks a stable locking structure, which can easily lead to safety hazards such as tilting or falling off of the aquaculture layers. At the same time, it does not have supporting structures for aeration, sewage discharge, and protection designed for the characteristics of snail farming, resulting in inconvenience in controlling the farming environment and difficulty in improving the snail survival rate. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a snail farming device based on a three-dimensional expansion structure.
[0005] The technical solution of the present invention is as follows: a snail farming device based on a three-dimensional expansion structure, comprising a device frame, an expansion component movably disposed on the device frame, and a farming box movably disposed on the expansion component; the device frame includes a base and longitudinal sliding columns movably disposed at the four corners of the upper end face of the base; The expansion assembly includes a rectangular sliding frame that is slidably engaged with a longitudinal sliding column via a sliding sleeve, adjusting columns located on both sides of the upper surface of the base, and climbing components located on both sides of the rectangular sliding frame and movably connected to the two adjusting columns respectively; several rectangular sliding frames are provided, and several breeding boxes are movably installed on the bottom surface of each rectangular sliding frame; T-shaped sliding grooves are provided on both sides of the bottom surface of the rectangular sliding frame. The upper surface of the breeding box is equipped with guide rollers on both sides that slide and engage with the T-shaped groove; there is a partition net at the bottom of the breeding box; a water inlet pipe is installed on the outer wall of the breeding box, and a sewage outlet pipe is installed on the bottom surface.
[0006] Furthermore, mounting slots are provided on both sides of the rectangular sliding frame; the climbing component includes a first movable plate that is slidably engaged inside the mounting slot, a connecting gear on the first movable plate that is rotatably engaged via a rotating shaft, a climbing motor that is mounted on the first movable plate and provides power to the rotating shaft, and a switching motor that is mounted inside the mounting slot and provides power to the first movable plate; a first rack is provided on the bottom surface of the first movable plate; a first sprocket is sleeved on the rotating shaft, and a second sprocket is provided at the output end of the climbing motor, with the second sprocket and the first sprocket connected by a chain drive; a switching gear that meshes with the first rack is provided at the output end of the switching motor; and a toothed plate that meshes with the connecting gear is provided on the side wall of the adjusting column. Explanation: By utilizing the switching motor, switching gear, and first rack, the meshing and disengagement of the connecting gear and the toothed plate can be achieved; at the same time, the rotating shaft is driven by the climbing motor, and the meshing action of the connecting gear and the toothed plate is used to achieve the smooth lifting and lowering of the rectangular sliding frame, so that the present invention can adapt to the interlayer spacing requirements of snails at different growth stages.
[0007] Furthermore, a second movable plate is slidably engaged inside the mounting slot and below the switching motor. A second rack is provided on the upper surface of the second movable plate, which is meshed with the switching gear. A locking tooth block is provided at the end of the second movable plate near the adjusting column, which can be movably engaged with the tooth plate. Explanation: When the rectangular sliding frame rises, the locking tooth block moves away from the toothed plate. When the first moving plate moves away from the adjusting column, the second moving plate moves closer to the adjusting column. At this time, the locking tooth block can engage and lock with the toothed plate on the adjusting column, thereby preventing the rectangular sliding frame from falling due to mechanical failure and improving the safety of the equipment.
[0008] Furthermore, the locking tooth block is movably connected to the second movable plate via a plug rod, and the second movable plate is provided with a return spring that abuts against the plug rod. Explanation: The locking tooth block is movably connected to the second moving plate using a plug rod. At the same time, the impact force when the locking tooth block and the tooth plate are locked is relieved by the action of the return spring.
[0009] Furthermore, an aerator is installed on the upper surface of the base, and an aeration pipe is installed on the lower side of the outer wall of each breeding box. Explanation: Using an aerator to introduce air into the water inside each breeding tank helps promote water circulation, reduces the accumulation of uneaten feed and feces in the water, helps improve water quality, reduces the risk of water pollution, and increases the survival rate and growth rate of snails.
[0010] Furthermore, a protective barrier is provided on the upper surface of the base and on the outside of the longitudinal sliding column, and a protective net is movably hinged to the protective barrier; Explanation: The protective enclosure solves the problem of snails being attacked by natural enemies such as birds and rodents during snail farming; the protective net that is hinged to the protective enclosure facilitates the feeding of food into the breeding box and the transfer of adult snails, improving the ease of use of the equipment.
[0011] Furthermore, a sunshade assembly is provided at the top of the protective fence. The sunshade assembly includes a ring frame at the top of the protective fence, a roller that is rotatably engaged with both sides inside the ring frame, a sunshade net that is wound around the two rollers respectively, and a retractor that is installed on the outer wall of the ring frame and provides power to one of the rollers. A drive box is provided on the outer wall of the ring frame. One end of each of the two rollers extends into the drive box and is connected to a pulley. The two pulleys are connected by a belt drive. Inside the ring frame, sliding rods are slidably engaged with sliding seats that are respectively connected to the ends of the two sunshade nets. Each sliding rod is fitted with a compression spring that abuts against the side of the sliding seat that is away from the two sliding seats. Explanation: By using a retractor to drive two rollers to rotate synchronously in opposite directions, the shade net can be quickly unfolded and retracted, making it easy to operate. This invention allows for flexible adjustment of the shade area according to weather conditions, further optimizing the snail's growth environment.
[0012] Furthermore, several partition mesh panels are vertically installed inside the breeding box and above the partition net; rubber protrusions are present on the inner wall of the breeding box; Explanation: The distribution of the breeding boxes into several independent but interconnected breeding chambers by using partition mesh panels can prevent snails from gathering excessively and ensure that the snails in each breeding chamber can obtain sufficient food and dissolved oxygen; by setting rubber protrusions, an attachment carrier can be provided for the snails, making it convenient for them to attach and rest.
[0013] Furthermore, a cover is movable on the outer wall of the breeding box; Note: The cover facilitates the transfer of snails inside the breeding box and also makes it easier to clean up impurities and uneaten feed.
[0014] The method of using this invention is as follows: In use, the rectangular sliding frame is slidably engaged with the longitudinal sliding column via the sliding sleeve, and then the breeding box is slidably engaged with the T-shaped sliding groove on the bottom surface of the rectangular sliding frame via the guide roller; adjust the number and spacing of the rectangular sliding frame and breeding box according to the snail breeding needs; then connect the water inlet pipe on each breeding box to the external water source, and connect the sewage pipe to the external sewage system.
[0015] Based on the snail growth cycle and farming scale, the equipment is expanded and adjusted. First, the switching motor is started, which drives the switching gear to rotate. The switching gear meshes with the first rack on the bottom surface of the first moving plate, driving the first moving plate to move along the mounting groove towards the adjusting column, so that the connecting gear meshes with the toothed plate on the side wall of the adjusting column. Then, the climbing motor is started, which drives the first sprocket to rotate through the second sprocket and chain, which in turn drives the rotating shaft and the connecting gear to rotate. The connecting gear moves up and down along the toothed plate, causing the rectangular sliding frame to rise and fall along the longitudinal sliding column, adjusting the spacing between adjacent rectangular sliding frames. After the rectangular sliding frame rises and falls to the designated position, the switching motor continues to drive the first moving plate to move. At the same time, through the engagement of the switching gear with the second rack on the second moving plate, the second moving plate is driven to move towards the adjusting column, so that the locking tooth block engages with the toothed plate, realizing the locking and fixing of the rectangular sliding frame. Then, the farming boxes are slid along the T-shaped slide groove using guide rollers to adjust the lateral arrangement of the farming boxes on the rectangular sliding frame, increasing or decreasing the number of farming boxes. Finally, after placing the snail larvae into the breeding tank, water is injected into the breeding tank through the water inlet pipe, and feed is put into each breeding tank. Air is continuously introduced into each breeding tank using an aerator to increase the dissolved oxygen level in the water.
[0016] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: First, the present invention has a reasonable structural design. It uses a climbing component to drive the rectangular sliding frame to move up and down along the adjusting column, while the breeding box is slidably attached to the bottom surface of the rectangular sliding frame. This enables the equipment to expand its capacity both vertically and horizontally, allowing the present invention to flexibly adjust the breeding space density according to the needs of different growth stages of snails, such as juvenile snails and adult snails, thereby increasing the snail breeding yield. Secondly, by setting up a shading component, the present invention uses a retractable motor to drive two rollers to rotate synchronously in opposite directions, which enables the rapid unfolding and retraction of the shading net. The operation is convenient, and the present invention can flexibly adjust the shading area according to the weather conditions, further optimizing the snail's growth environment and improving the quality of snail farming. Third, the equipment of this invention can be adapted to various breeding scenarios such as ponds, paddy fields, and artificial breeding ponds, without the need for large-scale modification of the breeding site, which helps to reduce site investment costs. At the same time, the equipment specifications can be flexibly adjusted according to the breeding scale, making it highly practical and promoting the efficiency of large-scale snail breeding.
