Description

Technical Field

[0001] The utility model relates to the technical field of seedling screening, in particular to an aquaculture seedling screening device. Background Art

[0002] During the growth of aquaculture seedlings, there is a phenomenon of mutual killing among some seedlings. The main manifestation is that some larger seedlings will kill and swallow smaller seedlings. In order to prevent this phenomenon from occurring, usually during the cultivation of seedlings, it is necessary to screen the seedlings and classify them according to the individual size of the seedlings and culture them in different ponds to reduce the mutual predation among the seedlings and improve the yield of the seedlings. In the prior art, when screening seedlings, usually workers use a sieve mesh plate to screen the seedlings. However, when the existing sieve mesh plate is used, it is necessary to screen the seedlings into different sizes, and it is necessary to prepare multiple sieve mesh plates of different specifications and screen the seedlings in turn to separate the seedlings of different sizes. It is impossible to screen multiple sizes of seedlings at the same time, which is very troublesome to use, the seedling screening efficiency is slow, and it is also very labor-consuming. Content of the Utility Model

[0003] The purpose of the utility model is to provide an aquaculture seedling screening device, which can conveniently screen different sizes of seedlings quickly at the same time, improve the seedling screening efficiency, and save labor.

[0004] The above technical purpose of the utility model is realized through the following technical solutions:

[0005] An aquaculture seedling screening device includes a water tank. An inlet is opened at the upper end of the water tank. A bracket is arranged around the inlet at the upper end of the water tank. One end of the bracket is slidably connected with a horizontally arranged first support rod. A plurality of springs are arranged at equal intervals between the lower end of the first support rod and the bracket. A second support rod is vertically arranged at the lower end of the first support rod. A first sieve plate, a second sieve plate and a third sieve plate are detachably arranged on the outer side of the second support rod from bottom to top in sequence. A plurality of first sieve holes are opened at equal intervals at the lower end of the first sieve plate. A plurality of second sieve holes are opened at equal intervals at the lower end of the second sieve plate. A plurality of third sieve holes are opened at equal intervals at the lower end of the third sieve plate. The diameters of the first sieve holes, the second sieve holes and the third sieve holes are arranged in increasing order in sequence;

[0006] One end of the bracket close to the first support rod is horizontally provided with a support rod above it. One end of the support rod is rotatably connected to a horizontally arranged rotating shaft. A driving device for driving the rotating shaft is arranged inside the bracket. One end of the rotating shaft close to the first support rod is provided with a sleeve rod. One end of the sleeve rod is provided with a sliding opening. A sliding block is connected inside the sleeve rod. One end of the sliding block away from the rotating shaft is provided with a sliding rod slidably connected to the sleeve rod. The free end of the sliding rod is rotatably connected to a roller slidably connected to the first support rod. One end of the sliding block close to the sliding opening is rotatably connected to a threaded rod movably connected thereto. The outer side of the threaded rod is threadedly connected to a U-shaped buckle slidably connected to the sleeve rod.

[0007] By adopting the above technical solution, during use, water is added to the water tank through the water inlet. The first sieve tray, the second sieve tray, and the third sieve tray are sequentially installed on the second support rod from bottom to top. Then the seedlings to be sieved are poured into the third sieve tray. The driving device is started. The driving device drives the rotating shaft to rotate relative to the support rod. The rotating shaft drives the sleeve rod to rotate. The sleeve rod drives the sliding rod to rotate along with it. The rotation of the sliding rod drives the roller to contact the first support rod, and then pushes the first support rod downward to compress the spring. The first support rod drives the second support rod downward, thereby driving the first sieve tray, the second sieve tray, and the third sieve tray to immerse into the water in the water tank. When the rotating shaft continues to rotate to no longer push the first support rod downward, the first support rod is pushed upward under the action of the spring, thereby driving the first sieve tray, the second sieve tray, and the third sieve tray to be pulled out of the water. The seedlings follow the water flow and are respectively screened through the third sieve holes, the second sieve holes, and the first sieve holes, thereby screening the seedlings. By different rotations of the rotating shaft, the first support rod is driven to rotate up and down reciprocally, quickly screening the seedlings. According to needs, the first sieve tray, the second sieve tray, and the third sieve tray can be selected to be installed on the second support rod, thereby screening seedlings of different sizes according to needs. Rotate the threaded rod relative to the sliding opening to make the U-shaped buckle not clamp the sleeve rod, and the sliding rod can be pulled to drive the sliding block to slide relative to the sleeve rod, thereby adjusting the length formed by the sleeve rod and the sliding rod. Then the distance that the first support rod is pushed downward by the roller changes, which can ensure that the water in the water tank can always submerge all the seedlings, facilitating the screening of the seedlings.

[0008] A further setting of the present utility model is that: a plurality of fixing holes are arranged at equal intervals at one end of the first support rod. One end of the first sieve tray, the second sieve tray, and the third sieve tray close to the second support rod are all movably connected with detachably arranged fixing bolts. Each fixing bolt is movably connected to the corresponding fixing hole and is detachably arranged.

[0009] A further setting of the present utility model is that: the driving device includes a driven pulley provided at one end of the rotating shaft away from the sleeve rod, a driving pulley rotatably connected near the driven pulley at the rear end of the bracket, a motor installed at the upper end inside the bracket for driving the driving pulley to rotate, and a transmission belt provided between the driving pulley and the driven pulley for transmission.

[0010] A further setting of the present utility model is that: one end of the bracket is provided with a power cord for connecting to a power source to supply power, and one end of the water tank is provided with a control button.

[0011] A further setting of the present utility model is that: one end of the water tank is communicated with a water outlet pipe, and a valve is provided at the free end of the water outlet pipe.

[0012] A further setting of the present utility model is that: a knob is provided at the free end of the threaded rod. Compared with the prior art, the present utility model has the following beneficial effects:

[0013] First, it can conveniently and quickly screen seedlings of different sizes at the same time, improve the screening efficiency of seedlings, save manpower. The rotating shaft drives the sleeve rod to rotate, the sleeve rod drives the sliding rod to rotate, so that the roller intermittently contacts the first support rod, thereby intermittently pushing the first support rod downward. The spring compresses to generate elastic force and drives the first support rod upward. Thus, the first sieve plate, the second sieve plate, and the third sieve plate move up and down reciprocally to contact the water in the water tank, and the seedlings pass through the third sieve holes, the second sieve holes, and the first sieve holes in sequence with the water flow, so as to screen the seedlings of different sizes.

[0014] Second, according to the size of the seedlings to be screened, select to install the first sieve plate, the second sieve plate, and the third sieve plate on the second support rod as needed. By rotating the threaded rod, the U-shaped buckle releases the sleeve rod, adjusts the length formed by the sliding rod and the sleeve rod, and changes the distance of pushing the first support rod downward. Ensure that when the first support rod moves downward to the lowest point, the seedlings can always be immersed in the water in the water tank, so that it is convenient to screen different seedlings as needed.
