Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and specifically relates to a snail breeding and harvesting device. Background Art

[0002] Snails are the general term for Mollusca, Mesogastropoda, Viviparidae, and Margarya. Snails are a kind of food that we often consume in daily life. Traditional snails grow naturally in rivers and ponds and are then captured manually. Such a method has a relatively high risk, and the captured snails cannot guarantee their quality. Therefore, at present, artificial breeding has begun, and harvesting is carried out through an automatic harvesting device. When breeding, snails generally adhere to the breeding net. When harvesting, mature commercial snails and young snails are not screened, resulting in young snails being mixed in the commercial snails sold. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a technical solution for a snail breeding and harvesting device.

[0004] A snail breeding and harvesting device includes a breeding net and a roller. The breeding net is wound around the roller. One end of the breeding net is provided with a pulling rope. The breeding net is pulled open through the pulling rope to place the breeding net into the breeding water body. A scraper is provided on one side of the roller, and a storage box is provided below the scraper. A sieve is provided in the storage box. When harvesting, the roller rotates to contract the breeding net. The snails attached to the breeding net are scraped by the scraper and fall into the storage box. The storage box is shaken to separate the young snails from the finished snails.

[0005] Further, it also includes floats and ropes. The floats are fixed on both sides of the breeding net through the ropes.

[0006] Further, a driving device is provided at the end of the roller. The driving device is a motor and / or a handle. The output shaft of the motor or the handle is fixedly connected to the rotating shaft of the roller.

[0007] Further, when the driving device is a motor and a handle, the motor and the handle are respectively provided at both ends of the roller.

[0008] Further, the roller is arranged on the edge of the breeding water body through a bracket. A bearing is provided at the top of the bracket. The rotating shaft of the roller is inserted into the inner ring of the bearing.

[0009] Further, two groups of scrapers are provided, which are respectively arranged on the upper and lower sides of the breeding net and are installed on the bracket through a connecting frame.

[0010] Further, an embedding groove is provided on the inner wall of the storage box, and the screen is snap-fitted in the embedding groove, dividing the storage box into a finished product area and a young snail area, and an opening is provided on the side wall of the young snail area.

[0011] Further, the storage box is of a split structure, including a finished product box and a young snail box, and the screen is provided at the bottom of the finished product box.

[0012] Further, a vibrating machine is provided at the bottom of the storage box, and the vibrating machine continuously shakes to screen the obtained snails.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The snail breeding and obtaining device of the present invention has a simple structure. When in use, pull out the breeding net and tie the pull rope to the fixed pile of the breeding pond to place the breeding net into the breeding water body. After breeding is completed, loosen the pull rope, and manually or click to rotate the roller to wind the breeding net around the roller. And capture the snails through the scraping plates arranged on the upper and lower sides of the breeding net. The scraped snails fall into the storage box at the bottom, and the vibrating machine runs continuously to screen the young snails and the finished commercial snails to complete the obtaining. When the device is not in use, the storage volume is small and the structure is also simple, having good economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Such as Figure 1-2As shown in the figure, a snail breeding and harvesting device includes a breeding net 1 and a drum 2. The drum 2 is arranged at the edge of the breeding water body through a bracket 10. A bearing 1001 is arranged at the top of the bracket 10, and the rotating shaft of the drum 2 is inserted into the inner ring of the bearing 1001. The breeding net 1 is wound around the drum 2. One end of the breeding net 1 is provided with a pulling rope 3. The breeding net 1 is pulled open through the pulling rope 3 and placed into the breeding water body. Then, piles are driven at corresponding positions in the breeding pond, and the pulling rope is fixed to the piles to achieve fixation. A scraper 4 is arranged on one side of the drum 2, and a storage box 5 is arranged below the scraper 4. A sieve mesh 6 is arranged in the storage box 5. During harvesting, the drum 2 rotates to contract the breeding net 1, and the snails attached to the breeding net 1 are scraped by the scraper 4 and fall into the storage box 5. The storage box 5 is shaken to screen the young snails and the finished snails.

[0021] Floaters 7 and ropes are arranged on the breeding net 1. The floaters 7 are fixed on both sides of the breeding net 1 through the ropes. When the breeding net 1 is put into the breeding pond, the breeding net floats or suspends in the water body through the floaters 7, which is convenient for snail breeding. To prevent the breeding net 1 from deforming when being pulled, a pull rod 12 is arranged at the end of the breeding net 1. The breeding net 1 is fixedly connected to the pull rod 12, and the pulling rope 3 is connected to the pull rod 12.

[0022] A driving device is arranged at the end of the drum 2. The driving device includes a motor 8 and a handle 9. The output shaft of the motor 8 and the handle 9 are fixedly connected to the rotating shaft of the drum 2. The motor 8 and the handle 9 are respectively arranged at both ends of the drum 2. By choosing to rotate the handle 9 or turn on the motor 8, the drum 2 is driven to rotate, and the breeding net is contracted when capturing snails.

[0023] To prevent the snails adsorbed on the bottom of the breeding net 1 from being crushed, two groups of scrapers 4 are arranged, which are respectively arranged on the upper and lower sides of the breeding net 1 and are installed on the bracket 10 through a connecting frame 11. When the drum rotates, the upper and lower sides of the breeding net are respectively scraped.

[0024] An embedded groove 501 is arranged on the inner wall of the storage box 5, and the sieve mesh 6 is clamped in the embedded groove 501, dividing the storage box 5 into a finished product area and a young snail area. An opening 502 is arranged on the side wall of the young snail area. A vibrator is arranged at the bottom of the storage box 5, and the vibrator continuously shakes to screen the obtained snails. After screening, the young snails are poured out through the opening 502.

[0025] Combined Figure 3 , the storage box 5 can also be of a split structure, including a finished product box and a young snail box. A sieve mesh 6 is arranged at the bottom of the finished product box. After screening, the finished product box is lifted, and the young snails can be obtained.

[0026] The snail breeding and harvesting device of the present invention has a simple structure. During use, the breeding net is pulled out, and the pulling rope is tied to the fixed stake of the breeding pond, so that the breeding net is placed into the breeding water body. After breeding is completed, the pulling rope is loosened, and the breeding net is retrieved and wound around the roller manually or by clicking to rotate the roller. Moreover, the snails are captured by the scraping plates arranged on the upper and lower sides of the breeding net, and the scraped snails fall into the storage box at the bottom. The vibrating machine continuously operates to screen the young snails and the commercial snails of the finished products, completing the harvesting. When the device is not in use, it has a small storage volume and a simple structure, having good economic benefits.

[0027] After the harvesting is completed, the breeding net is pulled open again through the pulling rope and placed in the breeding pond, and the screened young snails are re-scattered in the breeding pond.
