Description

Technical Field

[0001] The invention relates to the technical field of aquatic animal breeding, and in particular to seedling raising equipment and a seedling raising method for oyster breeding. Background Art

[0002] Oysters are a general term for mollusks of the family Ostreae, order Pectinata, also known as oysters, oyster roe, oysters, and sea oysters. The two shells of oysters are unequal, the left shell is larger and concave, and the right shell is flatter. The hinge is toothless, and sometimes has tubercle-shaped small teeth. The internal ligament and adductor muscle are located in the center or back. The mantle marks are not obvious, and adults have no feet and byssus. The gills are combined with the mantle. Oysters are distributed worldwide, mainly in tropical and temperate oceans, from intertidal zones to tens of meters deep. There are about a hundred species in the world, and about twenty species in the coastal areas of north and south China.

[0003] Chinese patent CN109511590B discloses an oyster culture attachment base, wherein an oyster attachment sheet is screwed into an opening and then inserted into the mudflat for fixing. After fixing, the oyster attachment sheet is rotated to a horizontal plane, and the oyster attachment sheets of adjacent base columns are staggered and crossed to improve space utilization. After the oysters grow up, the oyster attachment sheet is rotated into the opening, and an oyster scraping device is started. The extension and contraction of the oyster scraping device controls the oyster scraping head to press down from the hollow interior of the base column to scrape off the oysters attached to the inside of the base column.

[0004] When the above-mentioned seedling raising equipment is in use, the breeders need to place all the oysters to be cultured on the oyster attachment patches around the base column for adsorption. Since the adjacent oyster attachment patches are close to each other, the breeders need to place the oysters on the oyster attachment patches of each base column according to the size of the oysters. The breeding personnel need to place the oysters repeatedly around the base column, which will take a long time on a single base column. The delay will affect the overall placement progress and reduce production efficiency. Summary of the invention

[0018] To achieve the above object, the present invention provides the following technical solution: a method for raising oyster seedlings for oyster farming, comprising the following steps:

[0019] First, three placement seats are set on each layer of the outer circle of the outer base column.

The limiting pulleys in the horizontal slide groove and the inclined slide groove will gradually move from both sides to the middle as the intersection position changes, driving the moving placement seats on both sides to converge to the fixed placement seats in the middle, so that the three placement seats on one layer are The placement seats and cover plates converge to one side of the outer base column. When the movable placement seats and cover plates on both sides converge to the placement seat and cover plate fixed in the middle, the lifting components in the placement seats on both sides will gradually rise, and at the same time drive the lifting components in the placement seat in the middle to rise, lift one end of the oysters in the placement seat, and push down the handle on the mounting cover so that the T-shaped sliding column under the handle drives the tripod to move in the inner lifting cylinder. When the tripod moves downward, it will also drive the connecting rod downward, and the connecting rod will push the locking assembly to rotate and open the cover plates on all the placement seats, making it convenient to take out the cultured oysters in the placement seats.

[0020] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] 1. The inner lifting cylinder is pushed up along the inner wall of the outer base column by the lifting assembly, so that the limit pulleys in the horizontal slide grooves and the inclined slide grooves on both sides move with the change of the intersection, so that the placement seats and cover plates of one layer are gathered to one side, making it more convenient and quick for workers to take and place oysters, reducing the time consumption during the operation process, thereby improving the overall work efficiency. By pressing the handle on the installation cover and pushing the locking assembly downward through the connecting rod, the cover plates on all the placement seats are rotated and opened at the same time, and the breeders can check the breeding conditions of all oysters at the same time, which can greatly save manpower and time, allowing the breeders to quickly check and maintain the oysters and reduce the tedious operation of opening the covers one by one.

[0022] 2. By stepping on the pedal at the treading groove, the sliding column at one end of the pedal will slide from the left end to the right end of the through groove, so that the transmission rod with the through groove rotates and tilts on the fixed block, and the lifting plate is pushed up, which will drive the inner lifting cylinder in the outer base column to rise at the same time, so that the placement seat and the cover plate are gathered on one side of the outer base column, which is convenient for operators to pick quickly and orderly, avoid searching and operating one by one, and can greatly save time. Centralized operation can improve efficiency, reduce loss, and prevent falling or being neglected.

[0023] 3. When the placement seats and cover plates on both sides slide toward the middle by stepping on the lifting assembly, the lifting top block at one end of the placement seat will gradually rise with the movement, and the bottom end of the lifting top block will gradually rise along the inclined surface of the ramp ring, and will contact one end of the oyster in the placement seat, and lift up the oysters adsorbed on the inner walls of the placement seats on both sides. By lifting and disconnecting the adsorption of the oysters, the oysters can be removed from the placement seat more easily, which can prevent the farmers from cutting their hands when breaking the oysters, which not only improves the breeding efficiency and reduces the labor intensity, but also greatly improves the picking efficiency and reduces time waste.

[0024] 4. By pushing the handle downward, the connecting rod will drive the annular slide on the outer wall of the outer base column to move downward during the movement of the connecting rod along the limit groove, and drive the slide block at one end of the cover plate to move downward at the same time, so that all the cover plates rotate along the connecting block and open on the placement seat. One-button operation can quickly open all the cover plates, saving the time of opening the cover plates one by one, reducing labor input, reducing labor fatigue and labor costs, and the locking group can fix the position of the cover plate, freeing the hands of the breeder to better take and place oysters.

[0052] Furthermore, by rotating the handle 301 above the mounting cover 204, the two ends of the T-shaped slide column 302 are driven to rotate and engage along the inner wall of the locking slide groove 306, so that the connecting rod 304 is locked in the lowered position, and the cover plate 208 is locked in the rotated open state on the placement seat 207. Example

[0053] Reference Figure 1-Figure 3 , Figure 5 , Figure 8, which is a fourth embodiment of the present invention, provides a method for raising oyster seedlings for oyster farming, comprising the following steps:

[0054] Each layer of the outer circle of the outer base column 100 is provided with three placement seats 207, among which the placement seats 207 located between the horizontal slide grooves 201 on both sides are fixed, and the other two can slide along the horizontal slide grooves 201, and the inner lifting cylinder 202 in the outer base column 100 is pushed upward by the lifting component. In the process of the inner lifting cylinder 202 rising, the intersection position of the horizontal slide groove 201 on the outer wall of the outer base column 100 and the inclined slide groove 203 on the outer wall of the inner lifting cylinder 202 changes with the movement, and the limiting pulleys 205 in the horizontal slide groove 201 and the inclined slide groove 203 will gradually move from both sides to the middle as the intersection position changes, driving the placement seats 207 moving on both sides to converge to the fixed placement seat 207 in the middle, so that the three placement seats 207 and the cover plate of one layer are connected. 208 converge to one side of the outer base column 100. When the movable placement seats 207 and cover plates 208 on both sides converge to the placement seats 207 and cover plates 208 fixed in the middle, the lifting components in the placement seats 207 on both sides will gradually rise, and at the same time drive the lifting components in the placement seat 207 in the middle position to rise, and lift up one end of the oysters in the placement seat 207. By pushing the handle 301 on the mounting cover 204 downward, the T-shaped sliding column 302 under the handle 301 drives the tripod 303 to move in the inner lifting cylinder 202. When the tripod 303 moves downward, it will also drive the connecting rod 304 to move downward. The connecting rod 304 will push the locking assembly to rotate and open the cover plates 208 on all the placement seats 207, so as to facilitate the removal of the cultured oysters in the placement seats 207.
