Escape prevention mechanism for shrimp farming in rice field

Abstract

The invention discloses an escape prevention mechanism for shrimp farming in a rice field, which comprises a main retaining plate, a movable retaining plate and locking bars; a sludge retaining plateis arranged below the main retaining plate, support posts are arranged below the sludge retaining plate, the upper surface of the main retaining plate is in slope shape of 5-35 DEG, and the lower edgeof the upper surface of the main retaining plate is hinged to the edge of the side surface of the movable retaining plate; main locking holes matched with one ends of the locking bars are formed in the two end faces of the main retaining plate; the two end surfaces of the movable retaining plate are provided with auxiliary locking holes matched with the other ends of the locking bars; when the movable retaining plate is lowered and the side face of the movable retaining plate abuts against the side face of the movable retaining plate, one of the auxiliary locking holes can be directly lockedand connected to the main locking holes through one locking bar; when the movable retaining plate is raised and the side face of the movable retaining plate abuts against the side face of the main retaining plate, the other of the auxiliary locking holes can be directly locked and connected to the main locking holes through the other locking bar. The escape prevention mechanism for shrimp farmingin rice field can be well stably mounted, and has good escape prevention effect.

Description

technical field [0001] The invention relates to an anti-escape mechanism for raising shrimp in paddy fields. Background technique [0002] Lobster is a general term for 19 species of lobsters belonging to 4 genera of the cetaceae Decapod Lobster family Arthropoda, also known as prawns, faucet shrimps, shrimp heads, sea shrimps, etc. With the growing demand for crayfish in the market, many farmers directly use rice fields as breeding grounds for crayfish. Anti-escape in rice fields is an extremely important task in crayfish farming. In the prior art, a more effective anti-escape solution is to set up isolation nets and fix the isolation nets through support columns. Because crayfish will climb along the isolation net, the existing isolation net is relatively high, up to 2m. At the same time, devices such as isolation hoardings or plastic films will be installed on the top to prevent the lobster from climbing out of the isolation net. The higher the isolation net not only in...

AI Technical Summary

Problems solved by technology

The higher the isolation net not only increases the installation cost and manufacturing cost, but also the hoarding or plastic film on the top of the isolation net increases the wind resistance of the isolation net and reduces the wind resistance of the isolation device. When the wind is strong, the isolation The net blows down, causing economic loss, and the isolation net cannot go deep into the paddy field, so it is impossible to prevent the lobster from burrowing and escaping under the paddy field
