[0029] A control cabinet 4 is provided at the front end of the frame 1. A PLC controller is provided in the control cabinet. The controlled end of the throwing module and the controlled end of the lifting module are respectively connected to the output end of the PLC controller.

[0030] The frame 1 is also provided with a battery 7 for power supply.

[0031] The lifting module is a conventional lifting structure. In this embodiment, Figure 3 As shown, the lifting module adopts a scissor-type lift structure for lifting. In other embodiments, a screw nut structure, a sprocket chain structure, etc. can be used to control the lifting of the silo.

[0032] The throwing module includes a throwing roller 16 installed in the discharge chute 15. A conveying box 10 is provided at the front end of the silo 2. A conveying mechanism for driving the left and right throwing rollers 16 to move synchronously is provided in the conveying box 10.

[0033] The transmission mechanism includes a first pulley 24, a second pulley 25, a third pulley 27, and a fourth pulley 28. Figure 5 As shown, the first pulley 24 is connected to the second pulley 25 via a first belt, and the second pulley 25 is connected to the throwing roller 16 on the right side.

[0034] The third pulley 27 and the fourth pulley 28 are connected via a second belt, and the fourth pulley 28 is connected to the throwing roller 16 on the left side.

[0035] The transmission mechanism also includes a driving gear 23 and a driven gear 26. The driving gear 23 is coaxially arranged with the first pulley 24 and is connected to the rotating motor 22. The driven gear 26 is engaged with the driving gear 23 for transmission, and the driven gear 26 is coaxially arranged with the third pulley 27. The controlled end of the rotating motor is connected to the output end of the PLC controller.

[0036] During the throwing process, the PLC controller controls the rotating motor to achieve variable speed rotation of the throwing roller, and throws the feed in the discharge trough into the breeding trough to ensure that the feed is thrown more evenly.

[0037] In this embodiment, the use of a throwing roller to scatter the feed is only one structure of the scattering module. In other embodiments, the throwing module can also be implemented using other scattering structures, such as a horizontal disc rotating structure to scatter the feed.

[0038] The silo 2 is also provided with a quantitative pushing module for pushing the feed into the discharge channel 29. The quantitative pushing module includes push plates 19 symmetrically slidingly arranged at the bottom of the silo 2. The push plates 19 are connected by a two-way telescopic connecting rod assembly 21. The two-way telescopic connecting rod assembly 21 is connected to the electric push rod 20. The controlled end of the electric push rod 20 is connected to the output end of the PLC controller.

[0039] The two-way telescopic connecting rod assembly includes a movable plate connected to the movable end of the electric push rod 20, such as Figure 5 As shown, the front and rear sides of the movable plate are respectively installed with diamond-shaped connecting rod mechanisms located on the front and rear sides of the electric push rod 20. The hinge shaft at the rear end of the diamond-shaped connecting rod mechanism is fixedly installed on the movable plate, and the hinge shaft at the front end of the diamond-shaped connecting rod mechanism is slidably connected to the sliding groove on the movable plate. The hinge shafts at the left and right ends of the diamond-shaped connecting rod mechanism are respectively connected to the push plate 19 through bending plates.

[0040] When the electric push rod 20 moves, the movable end of the electric push rod 20 drives the movable plate to move forward, and at the same time the movable plate drives the rear end of the diamond connecting rod mechanism to move forward. The diamond connecting rod mechanism is compressed in the front-to-back direction and expanded in the left-to-right direction, so that the diamond connecting rod mechanism drives the push plate 19 to the left and right sides, and pushes the feed in the silo 2 to the discharge channel 29 and then pushes it out.

[0041] When the movable end of the electric push rod 20 retracts, the push plate 19 also moves in the opposite direction and resets under the drive of the diamond connecting rod mechanism, completing a cycle of pushing action. During the pushing process, if the pushing distance of the movable end of the electric push rod 20 is controlled, the amount of feed pushed out from the discharge channel 29 to the discharge trough 15 can be controlled, and then the amount of feed scattered per unit area can be controlled, which is convenient for adjusting the amount of feed fed according to the growth cycle of earthworms.

[0042] The inside of the silo 2 is provided with an inverted V-shaped protective plate 14 for protecting the quantitative pushing module. The bottom of the protective plate 14 is slidably fitted with the top surface of the pushing plate 19. Figure 4 As shown, a bracket 17 is provided inside the silo 2 above the push plate 19 , and an inverted V-shaped mounting plate 18 connected to the protective plate 14 is mounted on the bracket 17 .

[0043] Slanted baffles 13 are respectively provided on the left and right sides of the interior of the silo 2 above the discharge chute 15 to facilitate downward discharge of materials. The bottom of the discharge chute 15 and the bottom end of the slanted baffle 13 form a discharge channel 29.

[0044] A driving wheel set 5 is provided at the front end of the frame 1 , and a universal wheel 12 is installed at the center of the rear end of the frame 1 .

[0045] The driving wheel assembly 5 includes a driving motor and two driving wheels. The driving wheels are connected via a rotating shaft. The driving motor is connected to the rotating shaft and drives the rotating shaft to rotate. The controlled end of the driving motor is connected to the output end of the PLC controller.

[0046] The rear end of the frame 1 is also provided with a handle 6 for facilitating movement of the frame.

[0047] The front and rear ends of the frame 1 are respectively provided with guide components that are slidably fitted with the outer wall of the breeding trough in the breeding room to guide the frame 1.

[0048] The guide assembly includes guide brackets 9 respectively mounted on the front and rear sides of the frame 1. Figure 1 As shown, a vertically arranged guide roller 8 is installed on the guide bracket 9, and the guide roller 8 is slidably connected to the outer side wall of the breeding trough at the lower part of the channel of the breeding room 30.

[0049] A laser distance sensor 11 for measuring the travel distance of the frame is installed at the front end of the frame 1, and the output end of the laser distance sensor 11 is connected to the input end of the PLC controller.

[0050] The horizontal movement distance of the rack 1 can be measured by the laser distance measuring sensor 11, so that the PLC controller can control the rack to move to the next station.

[0051] Similarly, a laser ranging sensor 11 is also provided at the bottom of the silo 2 to detect the lifting height of the silo, so that the PLC controller can control the lifting of the silo between the upper and lower breeding tanks.

[0052] When in use, the entire equipment is manually moved to the passage inside the breeding room 30, and the position of the discharge trough is adjusted to correspond to the position of the first row of breeding troughs at the entrance. At the same time, the lifting module is adjusted to move the hopper to the lowest position corresponding to the position of the breeding trough at the bottom of the first row. The quantitative pushing module is controlled to push the feed from the discharge channel 29 to the discharge trough 15, and the feed in the discharge trough is thrown into the breeding trough through the throwing module.

[0053] After the bottom breeding trough is scattered, the lifting module is controlled to drive the silo 2 to the upper breeding trough for scattering again, and the above operation is repeated. The lifting module drives the silo to move up layer by layer to complete the scattering of the feed in the first row of breeding troughs, and then drives the silo back to the lowest working position.

[0054] Next, the driving wheel group 5 is controlled to drive the equipment to move forward to the position of the next row of breeding troughs, and the scattering steps of the first row of breeding troughs are repeated to complete the scattering.

[0055] After the scattering is completed in the top row of breeding troughs in each row, the lifting module controls the hopper to fall to the lowest working position, and the driving wheel group drives the equipment forward to scatter the next row of breeding troughs until all the scattering is completed. The equipment is driven back to the position of the first row of breeding troughs and can be transferred to other breeding rooms with manual assistance.

[0056] During different growth cycles of earthworms, by controlling the moving distance of the push plate in the quantitative pushing assembly, the amount of feed fed can be adjusted according to the actual needs of the earthworms, thereby facilitating better growth of the earthworms.

[0057] The present invention provides an automatic feeding device for earthworms. The device realizes the standardized operation of earthworm feeding through the cooperation of a lifting module, a throwing module, and a quantitative pushing module, thereby improving feeding efficiency and solving the problems of inconvenient manual feeding and high labor costs. In addition, the present invention also uses a PLC controller in conjunction with a laser ranging sensor to perform automated feeding operations, accurately measures the travel distance of the rack and the lifting height of the silo, and improves the accuracy of the equipment. During the feeding process, the breeding trough is fed in rows, and each row is operated in a sequence from low to high or from high to low. After each row is finished spreading the material, the silo is controlled to the lowest position and moved to the next row to repeat the spreading from low to high. The operation is convenient and management is facilitated.
