Background technique

Crab seedlings usually need to be screened before stocking, and seedlings with similar individual sizes are selected for stocking to ensure the quality of crab breeding in the later stage. Traditional screening methods are usually manually screened, and the manual screening workload is relatively large. The speed is slow, and the screening accuracy is not good due to the influence of human factors. In order to solve this problem, sorting machines for sorting have appeared in the market. The existing sorting machines have complex structures and high prices, and are not suitable for small and medium-sized farming. Therefore, it is very necessary to design a crab seed screening device for small and medium-sized farms.

The device for screening crab seedlings is characterized in that the four corners of the frame are fixedly provided with circular connecting columns, and the corresponding positions of the four corners of the sorting screen are provided with circular connecting holes.

The device for screening crab seed is characterized in that the area of the space enclosed by the upper edge of the baffle is larger than the area of the sorting screen.

The device for screening crab seedlings is characterized in that the inner surface of the chute is smooth.

The device for screening crab seedlings is characterized in that the outer edge of the sorting screen coincides with the inner edge of the frame.

The device for screening crab seedlings is characterized in that the elastic device is a spring fixing seat and a spring arranged on the receiving panel, and the other end of the spring is fixedly connected to the frame.

The utility model has a reasonable structural design, and can realize the grading and screening of crabs through the set sorting sieve, with high screening precision, reduced manual labor, and high efficiency; the sorting sieve and the frame are set in a detachable structure, which is convenient for different grading , The setting of the spring facilitates the vibration of the sorting screen and ensures the screening accuracy.

Description of drawings

Fig. 1 is the structural representation of the utility model;

In the figure, 1-sorting device, 2-receiving device, 3-frame, 4-sorting screen, 5-receiving panel, 6-supporting legs, 7-chute, 8-receiving container, 9-baffle, 10 -connecting column, 11-elastic fixing seat, 12-spring.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings of the description, and specific implementation methods will be given.

As shown in Figure 1, the utility model is a kind of device that is used for the screening of crab seedlings, is used for the screening before crab seedlings are put in a suitable place to breed, to guarantee the breeding standard of later stage is consistent, comprises sorting device 1 and is arranged under the sorting device The receiving device 2, the sorting device 1 comprises a square frame 3 and a sorting screen 4, the sorting screen 4 is detachably connected to the bottom of the frame 3, and the outer edge of the sorting screen 4 coincides with the inner edge of the frame 3, specifically For, the four corners of the frame 3 are fixedly provided with circular connecting columns 10, and the corresponding positions of the four corners of the sorting screen 4 are provided with circular connecting holes, and the sorting can be realized by fitting the circular connecting holes on the connecting columns. The connection between the sieve 4 and the frame 3, this kind of structure is arranged, is convenient to replace different sorting sieves according to the requirement of classification, and screens out crab seedlings of different specifications. Crabs are sorted to ensure that crabs of the same specification are screened out to improve product quality.

The receiving device is used to receive crabs of the same specification after sorting, including a square receiving panel 5 and support legs 6. In order to facilitate centralized collection, an inclined chute 7 is arranged on one side of the receiving panel 1, and the other end of the inclined chute A receiving container 8 is provided, and the crabs slide into the receiving container 8 from the upper end of the inclined chute 7. In order to minimize the damage to the crabs in the sorting process, the inner surface of the chute 7 is set as a smooth surface, and the smooth surface The setting of can also prevent crab from climbing, for preventing crab from falling on the ground from the sorting sieve, and crab crawling to the ground before entering the inclined chute on the receiving panel, on the other sides of the receiving panel 5 Both are provided with smooth baffles 9 inclined upwards, and the space area enclosed by the upper edge of the baffles 9 is larger than the area of the sorting screen; in order to achieve a better sorting effect, the square frame 3 and the receiving panel 5 are connected by an elastic device , The specific structure of the elastic device is that a spring fixing seat 11 and a spring 12 are arranged on the receiving panel 5 , and the other end of the spring 12 is fixedly connected with the frame 3 .

The working process of the present utility model is, according to classification needs, select suitable sorting sieve 4 and connect with frame 3 through connecting hole and connecting column, place the crab seedlings to be sorted on sorting sieve 4, carry out sorting , the crab species whose specifications are smaller than the screen holes automatically fall into the receiving panel 5, and then enter the receiving container 8 through the chute 7. In order to avoid the overlapping of the crabs on the sorting screen 4, the upper end of the frame 3 is pressed, and the spring 12 Drive the sorting screen 4 to vibrate under the effect of the action, and then realize better sorting effect.
