Description

Technical Field

[0001] This utility model belongs to the field of earthworm farming, and in particular relates to a spraying device for earthworm farming ponds. Background Technology

[0002] In earthworm farming, the breeding pond needs to be equipped with a sprinkler system to spray clean water into the pond, ensuring the humidity environment required for earthworm growth. Currently, the sprinkler system configured for earthworm breeding ponds includes a sprinkler pipe, which is moved to the upper part of the breeding pond via a screw-slide structure. The sprinkler pipe has downward-facing water outlets, and a clean water source is connected to the outside of the sprinkler pipe. During the movement of the sprinkler pipe, water is sprayed into the breeding pond through the water outlets.

[0003] During the breeding process, it was found that in the existing spraying mechanism, the length of the screw of the sliding table structure corresponding to the spray pipe is the same as the length of the breeding pond. This results in the moving distance of the moving part being less than the length of the breeding pond. In other words, the moving distance of the spray pipe when spraying is less than the length of the breeding pond, which makes the spraying effect at both ends of the breeding pond poor or even incomplete. This leads to uneven humidity in the pond, which affects the growth of earthworms and may even cause earthworms at that location to die from lack of water. Utility Model Content

[0004] In view of this, the present invention aims to provide a spraying device for earthworm breeding ponds to improve the uniformity of water spraying in the breeding ponds, thereby improving the quality and survival rate of earthworm breeding.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A sprinkler system for an earthworm farming pond includes a pond body and an outlet pipe. The outlet pipe is horizontally positioned within the pond body and opens near the top of the pond body. Several outlet holes are formed downwards on the outlet pipe. A first rotating shaft is provided at one end of the outlet pipe, and a second rotating shaft is provided at the other end. Sliding grooves are respectively formed on the two sides of the pond body corresponding to the first and second rotating shafts. The first and second rotating shafts are slidably installed in their respective sliding grooves, with the first rotating shaft extending out of the pond body through the corresponding sliding groove. A movable component is provided on the side of the pond body where the first rotating shaft extends. The moving component moves in a direction parallel to the sliding groove. A crank-connecting rod structure is provided between the movable component and the first rotating shaft. The crank-connecting rod structure drives the first rotating shaft to swing left and right around its own central axis. The movable component drives the crank-connecting rod structure and the outlet pipe to move.

[0007] Furthermore, the movable component corresponds to a lead screw slide, and the movable component is mounted on the slide block of the lead screw slide.

[0008] Furthermore, the crank-connecting rod structure includes a swing arm motor and a swing arm, a connecting rod, and a rotating arm that are sequentially hinged. The length of the swing arm is greater than the length of the rotating arm, and the swing arm is fixedly connected to the first rotating shaft. The swing arm motor is mounted on the moving part, and the rotating arm and the main shaft of the swing arm motor are fixedly connected. The swing arm motor is the power source for the crank-connecting rod structure.

[0009] Furthermore, a cover is provided on the side of the pool body where the first rotating shaft extends, and the cover encloses the crank connecting rod structure inside.

[0010] Furthermore, the water outlet pipe is a variable diameter pipe structure, including a first water outlet pipe and a second water outlet pipe connected to both ends respectively. The inner diameter of the first water outlet pipe is larger than the inner diameter of the second water outlet pipe, and a flexible hose connector is provided at the center of the top surface of the first water outlet pipe.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 , Figure 2As shown, a sprinkler system for an earthworm rearing pond includes a pond body 1 and a water outlet pipe 3. The pond body 1 is a rectangular structure with its opening facing upwards, used for raising earthworms. The water outlet pipe 3 is installed inside the pond body 1 along its wide side, close to the opening of the pond body 1. Both ends of the water outlet pipe 3 are closed, and a flexible hose connector 32 is installed at the middle of the top of its pipe wall. Several water outlet holes 31 are opened downwards on the pipe wall. When spraying is required, the flexible hose connector 32 is connected to a water source through a flexible hose, and high-pressure water is injected into the water outlet pipe 3, and then sprayed onto the rearing pond 1 through the water outlet holes 31.

[0026] One end of the water outlet pipe 3 is coaxially mounted with a first rotating shaft 4, and the other end is coaxially mounted with a second rotating shaft 2. Two long walls of the pool body 1 (one corresponding to the first rotating shaft 4 and the other to the second rotating shaft 2) have a sliding groove along their respective lengths near the top. The first rotating shaft 4 and the second rotating shaft 2 are slidably installed in their respective sliding grooves, allowing the water outlet pipe 3 to move along the length of the pool body 1 and rotate around its own central axis. The sliding groove corresponding to the first rotating shaft 4 is a through groove (penetrating the pool wall of the pool body 1), through which the first rotating shaft 4 extends to the outside of the pool body. A lead screw slide 9 is provided on the outer side of the long wall corresponding to the first rotating shaft 4 of the pool body 1. The lead screw slide 9 is located near the bottom of the pool body 1 and is arranged along the length of the pool body. The sliding block of the lead screw slide 9 moves in the same direction as the water outlet pipe 3. The sliding block is equipped with a movable component 5, which is a support plate or support block. The sliding block carries the movable component 5 to move. A crank-connecting rod structure 6 is set between the movable component 5 and the first rotating shaft 4. The crank-connecting rod structure 6 drives the first rotating shaft 4 to swing left and right around its own central axis. The movable component 5 drives the crank-connecting rod structure 6 and the water outlet pipe 3 to move, so that the water outlet pipe 3 can move and swing left and right to spray while moving in the breeding pond, thereby increasing the spraying area and spraying both ends of the breeding pond in place. This makes the water distribution in the breeding pond uniform, improves the quality and survival rate of earthworm breeding.

[0027] Crank and connecting rod structure 6 structure as follows Figure 1 , Figure 3 As shown, the structure includes a swing arm motor 8 and sequentially hinged swing arms 61, connecting rods 62, and rotating arms 63. The length of swing arm 61 is greater than the length of rotating arm 63, and swing arm 61 is fixedly connected to the first rotating shaft 4. The swing arm motor 8 is mounted on the moving part 5, and rotating arm 63 is fixedly connected to the swing arm motor main shaft 81. The crank-connecting rod structure 6 is a conventional technology and will not be described in detail here. The swing arm motor 8 is the power source for the crank-connecting rod structure 6, enabling the swing arm 61 to swing around its distal end (away from the end connected to the connecting rod 62), thereby driving the water outlet pipe 3 to swing, realizing the swing spray operation of the water outlet pipe.

[0028] The structure of water outlet pipe 3 is as follows Figure 4As shown, it is a variable diameter pipe structure, including a first water outlet pipe 33 and second water outlet pipes 34 connected to its two ends respectively. The second water outlet pipes 34 and the first water outlet pipe are coaxially arranged. The inner diameter of the first water outlet pipe 33 is larger than the inner diameter of the second water outlet pipe 34. A flexible hose connector 32 is provided on the first water outlet pipe 33. The use of this variable diameter pipe structure increases the water pressure entering the second water outlet pipe 34, making the water pressure close to the water pressure in the first water outlet pipe 33, thereby improving the uniformity of water output from the water outlet pipe 3 and achieving uniform spraying operation.

[0029] In this utility model, a cover 7 is provided on the side of the pool body 1 where the first rotating shaft 4 extends, and the cover 7 encloses the crank connecting rod structure 6 and the lead screw slide inside.

[0030] In this invention, the water outlet pipe moves and swings left and right to achieve full coverage spraying of the breeding pond, making the soil moisture distribution and humidity in the breeding pond uniform, thus improving the quality of earthworm breeding.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
