DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 and Figure 2 The utility model provides a technical solution: a fishing rack for shrimp farming, a handle 2 is fixedly installed on the upper rear end of the box body 1, and four universal wheels 6 are fixedly installed under the box body 1. The universal wheels 6 are convenient for moving the equipment according to needs during farming and fishing. A square groove 3 is opened on the upper surface of the box body 1, which is convenient for temporarily storing the shrimp fry in the square groove 3 when releasing the shrimp fry, and then putting it into the water after finding a suitable water area. When fishing, the caught shrimp can be put into the groove, and fishing can be done multiple times to improve work efficiency. During farming, the square groove 3 also plays the role of storing bait. The equipment is pushed to the water's edge and the shrimp can be placed according to the shrimp's position. Bait is put in according to the growth status, a telescopic device 4 is fixedly installed on the upper surface of the front side of the box body 1, and the length of the telescopic rod 42 can be adjusted as needed to facilitate large-area fishing, and a hand-cranked device 5 is installed on the outer surface of the telescopic device 4 close to the square groove 3. When fishing, the handle 51 is shaken to lift the fishing net 7, which is convenient for the user to operate. Two fixed pulleys 8 are fixedly installed on the top of the telescopic device 4 through a fixed frame 10. The rotation of the fixed pulley 8 drives the fishing rope 9 to work. The outer surfaces of the two fixed pulleys 8 are connected with fishing ropes 9, and one end of the fishing rope 9 is connected with the fishing net 7, which has a fishing effect through the net layer, so as to facilitate the large-scale fishing of shrimps.

[0019] like Figure 4 As shown, the telescopic device 4 includes an L-shaped bracket 41, one end of which is connected to a telescopic rod 42. The length can be adjusted according to work needs to facilitate fishing. Six spring pins 43 are provided on the left side of the telescopic rod 42. When the spring pins 43 are stuck in the fixing groove 44, the length of the telescopic rod 42 can be fixed. Three fixing grooves 44 are provided on the surface of one side of the bracket 41 close to the telescopic rod 42, and the spring pins 43 and the fixing grooves 44 are slidably installed.

[0020] like Figure 1 As shown, a connection groove 45 is provided on the surface of the telescopic rod 42 near the fixed pulley 8. When fishing, the fishing rod 9 passes through the connection groove 45 and extends to the bottom.

[0021] like Figure 1 As shown, a groove 11 is formed on the surface of the L-shaped bracket 41 near the square groove 3 to facilitate fixing the fixing block 56 on the groove 11 and facilitate installation and disassembly when the hand-crank device 5 is damaged.

[0022] like Figure 3 As shown, the hand-cranked device 5 includes a fixed block 56, which is fixedly mounted on the lower surface of the groove 11, and a cylindrical tube 55 is fixedly mounted on the upper surface of the fixed block 56. A spring 59 is fixedly mounted on the upper end of the fixed block 56, and the spring 59 supports the cylindrical tube 55. The spring 59 is sleeved in the cylindrical tube 55, and a fixed block 2 54 is mounted on the upper end of the cylindrical tube 55. A slot 57 is opened inside the fixed block 2 54, and a latch 58 is slidably connected to the slot 57 inside the fixed block 2 54. When it is necessary to fix the height of the fishing net 7, the latch 58 is inserted into the slot 57 to adjust the height of the fishing net 7. The required fishing height is determined by a cylindrical pin 53 fixedly connected to one end of the spring 59. During normal operation, the cylindrical pin 53 is placed in the cylindrical tube 55, and the latch 58 is inserted into the groove to press against the cylindrical pin 53 and pop up. The end of the L-shaped bracket 41 close to the square groove 3 is connected to the wire groove 52 through a coupling. When collecting the net, the fishing rope 9 is recovered into the wire groove 52, and the cylindrical pin 53 passes through the wire groove 52 and is slidably connected to the wire groove 52 to facilitate fixing the wire groove 52 and prevent it from sliding when collecting the net. A handle 51 is fixedly installed at one end of the wire groove 52 to facilitate the user to operate when collecting the net, saving time and effort.

[0023] Working principle: When using the device, pull the handle 2 to push the machine to the water's edge, shake the handle 51, the fixed pulley 8 rotates to drive the fishing rope 9 to work, shake the fishing rope 9 to the required length, cast the fishing net 7, and catch fish through the net layer. When collecting the net, shake the handle 51 to lift the fishing net 7. When catching shrimps far away, the telescopic rod 42 can be extended to a certain length to catch shrimps at a farther distance. When breeding, first store a large number of shrimp fry in the square groove 3, push the equipment to a suitable water area for release, and also put bait in the square groove 3 to feed the shrimps.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
