Description

Technical Field

[0001] The utility model relates to the technical field of rice crayfish farming, in particular to an anti-escape device for the edge of a paddy field for rice crayfish farming. Background Technique

[0002] Paddy field farming is an ecological farming mode that conducts a virtuous cycle in the paddy field ecosystem according to the principles of ecological economics. Paddy field farming can harvest a considerable amount of aquatic products under the conditions of saving labor, effort, and bait, and can also increase the rice yield by more than 10% without increasing the input. Due to the rich organic matter in the paddy field water area, it is very suitable for crayfish farming.

[0003] In the process of crayfish paddy field farming, preventing crayfish from escaping is an extremely important task. Currently, for preventing crayfish from escaping, mainly a net is used to block the edge of the paddy field. However, the net is convenient for crayfish to climb, and crayfish often climb over the anti-escape device by relying on rice plants or the mesh of the net. Moreover, the installation process of the net requires first inserting a support column and pulling the net on the surface of the support column, and the operation is cumbersome. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-escape device for the edge of a paddy field for rice crayfish farming. The device is provided with a first support column and a second support column, and a smooth baffle is arranged between the first support column and the second support column. By using the connection and cooperation between different first support columns and second support columns, the problems raised in the above background technique are solved.

[0013] With the above technical solution, the traction rod can drive the thin film to move, thereby connecting multiple assembly units.

[0014] Preferably, the length of the traction rod is longer than the opening on the surface of the second support column.

[0015] With the above technical solution, the traction rod always fits on the surface of the second support column.

A clamping rod 9 is rotatably connected to the outer surface of the connecting rod 8. The clamping rod 9 is in clamping fit with the square groove on the surface of the mounting block 6;

[0033] Such as Figure 1 , Figure 2 and Figure 4As shown in the figure, when using this device, hold the first support column 1 and the second support column 2 and insert them into the paddy field, so that the conical support rod 5 is inserted downward into the paddy field to fix one assembly unit. At this time, connect the first support column 1 of another assembly unit with the second support column 2 of this assembly unit. During the connection process, insert the engaging rod 9 on the surface of the connecting block 7 into the circular through hole on the surface of the mounting block 6, and rotate the engaging rod 9 on the surface of the engaging rod 9 so that the engaging rod 9 is engaged with the square groove on the surface of the mounting block 6, so as to connect the two assembly units. When disassembling and assembling, stretch the telescopic connecting rod 8, rotate the engaging rod 9 in the reverse direction so that the engaging rod 9 fits on the surface of the connecting rod 8, and pull out the connecting rod 8 from the through hole on the surface of the mounting block 6, so that the two assembly units on both sides are separated.

[0034] This device has the effect of film connection, specifically:

[0035] A traction structure is arranged inside the second support column 2. The traction structure arranges a film 11 to flexibly connect multiple assembly units. The traction structure includes a rotating cylinder 10. The inside of the second support column 2 is a hollow structure. A rotating cylinder 10 is rotatably arranged inside the second support column 2. One end of the film 11 is fixed on the surface of the rotating cylinder 10. The other end of the film 11 passes through the opening on the surface of the second support column 2 after being wound around the rotating cylinder 10 and is connected with a traction rod 12. The upper end of the rotating cylinder 10 passes through the surface of the second support column 2 and is connected with a knob 13. The length of the traction rod 12 is longer than the opening on the surface of the second support column 2. A card slot 14 is arranged on the surface of the first support column 1, and the card slot 14 is of the same length as the traction rod 12. A first clamping block 15 is rotatably arranged on the surface of the first support column 1, and a second clamping block 16 is fixedly arranged on the surface of the first support column 1.
