Description

Technical Field

[0001] The utility model relates to a single-room stacked shrimp and crab breeding device. Background Art

[0002] The current mainstream method of raising shrimps and crabs is pond farming. This farming method makes it difficult to prevent and control diseases and regulate temperature. Due to uneven feeding, the sizes of the individuals are not uniform. At the same time, most shrimps and crabs attack and cannibalize each other, resulting in a low survival rate and a sharp drop in production.

[0003] This problem also exists in the facility-based breeding model. For example, Chinese utility model No. CN 212325145 U discloses a multi-layer indoor lobster breeding box, which uses independent breeding boxes stacked on top of each other. Each breeding box has an independent water inlet and drainage device. Although this method can increase the breeding density, multiple shrimps need to be cultured in one breeding box, which is easy to cause fighting and attacking (especially when molting) and greatly affects the yield.

[0004] Therefore, it is necessary to design a new shrimp and crab breeding equipment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a single-room stacked shrimp and crab breeding device, which has a simple structure, is easy to implement, and can accurately and conveniently feed.

[0006] The technical solution of the utility model is as follows:

[0007] A single-room stacked shrimp and crab farming device comprises a sleeve-type feeding mechanism and a plurality of farming units for farming shrimp and crabs;

[0008] The sleeve-type bait throwing mechanism is composed of a sleeve and an inner tube;

[0009] The culture unit is a square box-shaped container without a cover, and the side and bottom surfaces of the culture unit are mesh surfaces or grid surfaces;

[0010] The bottom surface of each breeding unit is provided with a through hole for inserting a casing;

[0011] Multiple breeding units are mounted on the casing in a stacked manner;

[0012] A plurality of windows are provided at equal intervals on the sleeve along the axial direction of the sleeve, and a plurality of bait troughs are provided on the inner tube along the axial direction of the inner tube corresponding to the plurality of windows; the sleeve and the inner tube are both arranged in a vertical direction; under the action of an external force, the inner tube can rotate in the sleeve. When the windows are rotated to align with the bait troughs, the bait troughs are exposed in the breeding unit, so that shrimps and crabs can obtain the bait in the bait troughs and complete feeding.

[0013] The invention also comprises a base, a cover plate and a vertically arranged support rod, wherein the support rod is used to support one side of the plurality of breeding units to increase the stability of the breeding units.

[0014] The sleeve and the support rod are fixed on the base;

[0015] The cover plate is arranged on the top of the support rod and is located above the breeding unit (used to cover and press the breeding unit to achieve stability of the entire device).

[0016] The support rod is provided with a pin hole and a latch matched with the pin hole. After the cover plate presses a plurality of breeding units, it is locked with the latch, making the whole device more stable.

[0017] The sleeve-type feeding mechanism and the breeding unit are composed of two groups, and are arranged symmetrically relative to the support rod.

[0018] A plurality of inner tube windows are arranged at equal intervals along the axial direction of the inner tube, and a plurality of partitions are arranged at equal intervals in the inner tube along the axial direction of the inner tube. Each inner tube window and the partition form a bait trough.

[0019] Beneficial effects:

[0020] The single-room stacked shrimp and crab breeding device of the utility model has the following technical advantages:

[0021] (1) Use single-room (breeding unit) breeding, with one shrimp or one crab raised in each breeding unit to avoid mutual aggression, ensure uniform feeding, and improve the growth rate and survival rate of shrimps and crabs.

[0022] (2) The unique feeding device makes feeding accurate and convenient.

[0023] The method of combining the casing and the inner tube for feeding is adopted, which ensures accurate feeding and high bait utilization rate.

[0024] (3) Layered combined breeding saves space, has high breeding density and considerable economic benefits.

[0025] (4) With the casing as the axis, each breeding unit can be rotated or lifted to open, which is convenient for the release and collection of crabs, reduces labor intensity, can be operated by one person, and is suitable for breeding of different scales.

[0026] In summary, this single-room stacked shrimp and crab farming device adopts a brand-new structure and concept, with accurate and convenient feeding and easy operation. It can achieve high density and high survival rate of shrimp and crab farming, has good economic benefits, and is suitable for promotion and implementation. BRIEF DESCRIPTION OF THE DRAWINGS
