[0014] An automatic feed-supplementing earthworm farming method, applicable to the aforementioned automatic feed-supplementing earthworm farming equipment, includes the following steps: S1: Feeding; The lifting plate is driven to move down by the electric telescopic rod and the slotted plate is inserted into the breeding bed. Then the vehicle moves and the surface of the breeding bed is slotted. Under the resistance of the soil, the tension spring is stretched and the slotted plate moves towards the feed box. The connecting rod drives the toothed plate to move synchronously, which drives the second gear to rotate the valve ball, so that the feed pipe can be opened and automatic feeding can be realized. S2: Oxygen supplementation; When feeding is carried out by the rotation of the spiral blade driven by the second motor, the rotating wheel rotates synchronously. The piston is driven to move back and forth in the cylinder through the first and second protrusions, so that the two one-way valves are alternately opened, injecting air into the channel and into the breeding bed through the air hole, improving the ventilation of the breeding bed and increasing oxygen penetration. S3: Water replenishment; Water from the water tank is pumped into the spray pipe and sprayed onto the surface of the breeding bed by the nozzle. At the same time, the fourth shaft is driven by the third motor to rotate, which drives the extrusion blocks on both sides to rotate synchronously, injecting the EM solution from the solvent tank into the water outlet pipe. The EM solution is then evenly mixed into the water by the stirring rod and finally sprayed onto the surface of the breeding bed by the nozzle, and comes into contact with the subsequent feed.

[0015] The present invention provides an earthworm farming device and method with automatic feed replenishment, the beneficial effects of which include: 1. By setting up a feeding mechanism, the lifting plate can be driven down by an electric telescopic rod, and the slotted plate can be inserted into the breeding bed. Then the vehicle body moves, which can slot the surface of the breeding bed. Under the resistance of the soil, the tension spring is stretched, and the slotted plate moves towards the feeding box. The connecting rod drives the toothed plate to move synchronously, driving the second gear to drive the valve ball to rotate, which can open the feeding pipe and realize automatic feeding. The deeper the slotted plate is inserted into the breeding bed, the greater the soil resistance, the greater the movement of the slotted plate, and the greater the opening of the valve ball, thus realizing automatic control of the feeding amount.

[0016] 2. By setting up an auxiliary mechanism, when the second motor drives the spiral blade to rotate for feeding, it drives the rotating wheel to rotate synchronously. The first and second protrusions drive the piston to move back and forth in the cylinder, causing the two one-way valves to alternately open, injecting air into the channel and into the breeding bed through the air holes. This improves the ventilation of the breeding bed, increases oxygen penetration, increases the oxygen concentration in the bed soil, prevents local anaerobicness, promotes the metabolic activity of earthworms, and promotes the activity of aerobic microorganisms after the oxygen enters. Beneficial bacteria decompose feed faster, improve feed conversion rate, and make it easier for earthworms to eat.

[0017] 3. By setting up a spray mechanism, a water pump can inject water from the water tank into the spray pipe, which is then sprayed onto the surface of the breeding bed. This ensures the humidity of the breeding bed and mimics rainwater, driving away shallow earthworms and preventing the slotted plate from injuring them. Simultaneously, a third motor drives a fourth rotating shaft, which in turn rotates the extrusion blocks on both sides, injecting the EM solution from the solvent tank into the water outlet pipe. The stirring rod evenly mixes the EM solution into the water, which is then sprayed onto the surface of the breeding bed and comes into contact with the subsequent feed. The microbial community can quickly decompose organic matter into smaller molecules that are more easily absorbed by earthworms. Furthermore, the aeration of the bed soil through the pores can improve the conversion efficiency of the microbial community. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Black soldier fly larvae sand is a byproduct of black soldier fly larvae processing organic waste. It has disadvantages such as high salt content, high moisture content, easy fermentation, heat generation, and foul odor. If it is directly applied to farmland as organic fertilizer, it is easy to degrade and ferment again in the soil environment, causing soil heat generation and damage to crop roots. At the same time, it is easy to increase the soil salinity, resulting in crop yield reduction. Therefore, black soldier fly larvae sand cannot be used directly in agricultural production. By mixing black soldier fly larvae sand with low-salt materials (rice straw) and carrying out rapid high-temperature composting (about 15 days), earthworm feed can be made for earthworm farming. This not only realizes the reuse of organic waste and reduces the pressure on the environment, but also reduces the cost of purchasing special earthworm feed and increases the economic benefits of farming.

[0022] Traditional earthworm farming often encounters problems such as poor soil aeration, difficulty in regulating humidity, and a lack of diverse nutrient content in the feed. Earthworm feed produced through rapid high-temperature composting has a loose structure, increasing the porosity of the earthworm farming substrate, improving aeration, and providing sufficient oxygen for earthworms, which is beneficial for their respiration and growth. Simultaneously, this earthworm feed can absorb and retain a certain amount of moisture while preventing the earthworm farming substrate from becoming too wet, thus playing a role in humidity regulation during the farming process. Furthermore, this earthworm feed is mainly composed of black soldier fly larvae sand and rice straw. Black soldier fly larvae sand is rich in protein, amino acids, minerals, and other nutrients, making it an excellent food source for earthworms. Rice straw contains carbohydrates such as cellulose and hemicellulose, which, after microbial decomposition, provide an energy source for earthworms. Therefore, the earthworm feed produced by mixing black soldier fly larvae sand with low-salt materials (rice straw) and undergoing rapid high-temperature composting forms a more comprehensive nutritional system, meeting the nutritional needs of earthworm growth and reproduction.

[0023] Reference Figures 1-11 As shown, the present invention provides a technical solution: an earthworm farming device with automatic feed replenishment, including a vehicle body 1, a vehicle bucket 2, and a feeding bin 3. The vehicle bucket 2 is installed on the surface of the vehicle body 1 for storing feed. The feeding bin 3 is installed at the bottom of the vehicle bucket 2.

In use, the vehicle body 1 is moved to the side of the farming bed, and the first motor 7 drives the second rotating shaft 5 and the winding roller 6 to rotate, so that the feed box 4 is lowered and placed on the surface of the farming bed.

[0024] Reference Figures 1-9As shown, in a preferred embodiment, a feeding mechanism 8 is installed on the surface of the vehicle body 1 for replenishing feed. The feeding mechanism 8 includes a first rotating shaft 801, a lifting plate 804, and a feeding pipe 810. The first rotating shaft 801 is rotatably installed in the inner cavity of the feeding bin 3. A spiral blade 802 is installed on the surface of the first rotating shaft 801. A second motor 803 is fixedly installed on the side wall of the feeding bin 3. The output end of the second motor 803 is fixedly connected to the first rotating shaft 801 for driving the spiral blade 802 to rotate. The spiral blade 802 can be driven to rotate by the second motor 803, thereby pushing the feed in the truck bed 2 into the conveying box 4. The lifting plate 804 is slidably installed on the side wall of the conveying box 4. An electric telescopic rod 805 is fixedly installed on the side wall of the conveying box 4. The telescopic end of the electric telescopic rod 805 is fixedly connected to the lifting plate 804. A first slider 806 is fixedly installed on the side wall of the lifting plate 804. The first slider 806 is slidably installed on the side wall of the conveying box 4.

[0025] Reference Figures 1-9As shown, in a preferred embodiment, a slotted plate 807 is slidably mounted on the bottom of the lifting plate 804. The slotted plate 807 is V-shaped, and a second slider 808 is fixedly mounted on the surface of the slotted plate 807. The second slider 808 is slidably mounted in the inner cavity of the lifting plate 804. Tension springs 809 are symmetrically mounted in the inner cavity of the lifting plate 804. One end of the tension spring 809 is fixedly connected to the lifting plate 804, and the other end of the tension spring 809 is fixedly connected to the second slider 808. These springs are used to drive the slotted plate 807 to move away from the conveyor box 4 via an electric telescopic rod. 805 can drive the lifting plate 804 to move down and insert the slotted plate 807 into the breeding bed. Then the vehicle body 1 moves, and the surface of the breeding bed can be slotted. The depth of the slotted plate 807 inserted into the breeding bed is 1-3 cm. The feeding pipe 810 is symmetrically installed at the bottom of the feeding box 4. The inner cavity of the feeding pipe 810 is rotatably installed with a valve ball 811. The side wall of the valve ball 811 is fixedly installed with a third rotating shaft 812. One end of the third rotating shaft 812 is fixedly installed with a second gear 813. The inner cavity of the feeding box 4 is slidably installed with a toothed plate 814. The toothed plate 814 and the second gear 813 are slidably installed in the feeding box 4. Two gears 813 mesh to drive the valve ball 811 to rotate.

A slide rail 817 is fixedly installed on the side wall of the slotted plate 807, and the limit ring 816 is slidably engaged in the slide rail 817. A feed plate 818 is symmetrically fixedly installed at the bottom of the feed box 4. The slotted plate 807 is inserted into the breeding bed. When the vehicle body 1 moves forward to slot, the tension spring 809 is stretched under the resistance of the soil, and the slotted plate 807 moves towards the feed box 4. The connecting rod 815 drives the toothed plate 814 to move synchronously, which in turn drives the second gear 813 to rotate the valve ball 811, thus opening the feed pipe 810 for automatic feeding. The deeper the slotted plate 807 is inserted into the breeding bed, the greater the soil resistance it encounters, and the greater the movement of the slotted plate 807. This results in a larger opening of the valve ball 811, enabling automatic control of the feeding amount. When the slotted plate 807 is removed from the breeding bed, the tension spring 809 resets, driving the valve ball 811 to reset, thus automatically closing the feed pipe 810 and preventing feed waste.

[0026] In a preferred embodiment, during use, the vehicle body 1 is moved to the side of the breeding bed, and the second rotating shaft 5 and the winding roller 6 are driven to rotate by the first motor 7, lowering the feed box 4 and placing it on the surface of the breeding bed. The lifting plate 804 is driven to move down by the electric telescopic rod 805, and the grooving plate 807 is inserted into the breeding bed. Then, the vehicle body 1 moves to groov the surface of the breeding bed. Under the resistance of the soil, the tension spring 809 is stretched, and the grooving plate 807 moves towards the feed box 4, and is connected by the connecting rod 815. The toothed plate 814 moves synchronously, driving the second gear 813 to rotate the valve ball 811, which opens the feed pipe 810 for automatic feeding. The deeper the slotted plate 807 is inserted into the breeding bed, the greater the soil resistance it encounters, and the greater the movement of the slotted plate 807. This results in a larger opening of the valve ball 811, enabling automatic control of the feeding amount. When the slotted plate 807 is removed from the breeding bed, the tension spring 809 resets, driving the valve ball 811 to reset, which automatically closes the feed pipe 810 and prevents feed waste.

[0027] Reference Figures 1-9 As shown, in a preferred embodiment, an auxiliary mechanism 9 is installed on the surface of the vehicle body 1. The auxiliary mechanism 9 includes a through groove 901 and air holes 902. The through groove 901 is opened in the inner cavity of the slotted plate 807. Several air holes 902 are opened at the bottom of the slotted plate 807. The air holes 902 are connected to the through groove 901 and are used to inject air into the breeding bed to improve the ventilation of the breeding bed, increase oxygen penetration, increase the oxygen concentration in the bed soil, prevent local anaerobicness, promote the metabolic activity of earthworms, and promote the activity of aerobic microorganisms after the oxygen enters. Beneficial bacteria decompose feed faster, improve feed conversion rate, and make it easier for earthworms to eat.

[0028] Reference Figures 1-9 As shown, in a preferred embodiment, a cylinder 903 is fixedly installed on the side wall of the feeding hopper 3. A rotating wheel 904 is fixedly installed at one end of the first rotating shaft 801. A first protrusion 905 is fixedly installed on the surface of the rotating wheel 904.

One end of the spring 908 is fixedly connected to the cylinder 903, and the other end of the spring 908 is fixedly connected to the piston 906, which is used to drive the piston 906 to move towards the rotating wheel 904. One-way valves 909 are symmetrically installed on the side wall of the cylinder 903. One of the one-way valves 909 is connected to the through groove 901 by an air pipe.

[0029] In a preferred embodiment, when the second motor 803 drives the spiral blade 802 to rotate for feeding, it drives the rotating wheel 904 to rotate synchronously. Under the action of the spring 908, the piston 906 is pressed tightly against the surface of the rotating wheel 904. The first protrusion 905 and the second protrusion 907 can drive the piston 906 to move back and forth in the cylinder 903, causing the two one-way valves 909 to be alternately opened, injecting air into the channel 901 and into the breeding bed through the air hole 902. This improves the ventilation of the breeding bed, increases oxygen permeability, increases the oxygen concentration in the bed soil, prevents local anaerobicness, promotes the metabolic activity of earthworms, and promotes the activity of aerobic microorganisms after the oxygen enters. Beneficial bacteria decompose feed faster, improve feed conversion rate, and make it easier for earthworms to eat.

[0030] Reference Figures 1-11 As shown, in a preferred embodiment, a spraying mechanism 10 is installed on the surface of the vehicle body 1 for spraying the breeding bed to maintain soil moisture. The spraying mechanism 10 includes a water tank 1001, a water outlet pipe 1002, and a spray pipe 1004. The water tank 1001 is fixedly installed on the surface of the vehicle body 1. The water outlet pipe 1002 is installed on the side wall of the water tank 1001. A water pump 1003 is installed inside the water tank 1001. The water outlet of the water pump 1003 is connected to the water outlet pipe 1002. The spray pipe 1004 is rotatably installed on the side wall of the water outlet pipe 1002. Spray nozzles 1005 are symmetrically installed at the bottom of the spray pipe 1004. The water in the water tank 1001 can be injected into the spray pipe 1004 by the water pump 1003 and sprayed onto the surface of the breeding bed by the spray nozzles 1005. On the one hand, this can maintain the humidity of the breeding bed, and on the other hand, it can mimic rainwater to drive away the earthworms in the shallow layer and prevent the slotted plate 807 from injuring the earthworms.

[0031] Reference Figures 1-11 As shown, in a preferred embodiment, a solvent tank 1006 is installed on the surface of the water tank 1001 for storing EM bacteria solution. A squeezing cylinder 1007 is fixedly installed on the side wall of the water outlet pipe 1002. A flexible tube 1008 is installed in the squeezing cylinder 1007. One end of the flexible tube 1008 is connected to the water outlet pipe 1002, and the other end of the flexible tube 1008 is connected to the solvent tank 1006. A fourth rotating shaft 1009 is rotatably installed inside the water outlet pipe 1002. Several stirring rods 1010 are symmetrically fixedly installed on the surface of the fourth rotating shaft 1009 for mixing the EM bacteria solution into the water. Squeezing blocks 1011 are symmetrically fixedly installed on the side wall of the fourth rotating shaft 1009 for pressing the EM bacteria solution in the flexible tube 1008 into the water outlet pipe 1002. A third motor 1012 is fixedly installed on the side wall of the squeezing cylinder 1007. The output end of the third motor 1012 is fixedly connected to the fourth rotating shaft 1009.

[0032] In a preferred embodiment, during use, water from the water tank 1001 is injected into the spray pipe 1004 by the water pump 1003 and sprayed onto the surface of the breeding bed by the nozzle 1005. This ensures the humidity of the breeding bed and mimics rainwater to drive away shallow earthworms, preventing the slotted plate 807 from injuring them. Simultaneously, the third motor 1012 drives the fourth rotating shaft 1009 to rotate, causing the two side extrusion blocks 1011 to rotate synchronously, injecting the EM solution from the solvent tank 1006 into the water outlet pipe 1002. The stirring rod 1010 evenly mixes the EM solution into the water, and finally sprays it onto the surface of the breeding bed by the nozzle 1005, where it comes into contact with the subsequent feed. The microbial community can quickly decompose organic matter into small molecules that are more easily absorbed by earthworms, and the aeration of the bed soil through the pores 902 can improve the conversion efficiency of the microbial community.

[0033] Specifically, the working principle of this automatic feed-supplementing earthworm farming equipment is as follows: During use, the vehicle body 1 is moved to the side of the farming bed. The first motor 7 drives the second rotating shaft 5 and the winding roller 6 to rotate, lowering the feed box 4 onto the surface of the farming bed. The electric telescopic rod 805 drives the lifting plate 804 downwards, inserting the grooving plate 807 into the farming bed. Then, the vehicle body 1 moves, creating grooves on the surface of the farming bed. Under the resistance of the soil, the tension spring 809 stretches, causing the grooving plate 807 to move towards the feed box 4. The connecting rod 815 drives the toothed plate 814 to move synchronously, which in turn drives the second gear 813 to rotate the valve ball 811, thus opening the feed pipe 810 for automatic feeding. The deeper the slotted plate 807 is inserted into the breeding bed, the greater the soil resistance it encounters, and the greater the movement of the slotted plate 807. This results in a larger opening of the valve ball 811, enabling automatic control of the feeding amount. When the slotted plate 807 is removed from the breeding bed, the tension spring 809 resets, driving the valve ball 811 to reset, thus automatically closing the feed pipe 810 and preventing feed waste.

[0034] When the second motor 803 drives the spiral blade 802 to rotate for feeding, it drives the rotating wheel 904 to rotate synchronously. Under the action of the spring 908, the piston 906 is pressed tightly against the surface of the rotating wheel 904. The first protrusion 905 and the second protrusion 907 drive the piston 906 to move back and forth in the cylinder 903, causing the two one-way valves 909 to alternately open, injecting air into the channel 901 and into the breeding bed through the air hole 902. This improves the ventilation of the breeding bed, increases oxygen penetration, increases the oxygen concentration in the bed soil, prevents local anaerobicness, promotes the metabolic activity of earthworms, and promotes the activity of aerobic microorganisms after the oxygen enters. Beneficial bacteria decompose feed faster, improve feed conversion rate, and make it easier for earthworms to eat.

[0035] Water from the water tank 1001 can be pumped into the spray pipe 1004 by the water pump 1003, and then sprayed onto the surface of the breeding bed by the nozzle 1005. This ensures the humidity of the breeding bed and mimics rainwater to drive away earthworms in the shallow layer, preventing the slotted plate 807 from injuring them. At the same time, the third motor 1012 drives the fourth rotating shaft 1009 to rotate, which in turn drives the two extrusion blocks 1011 to rotate synchronously, injecting the EM solution from the solvent tank 1006 into the water outlet pipe 1002. The stirring rod 1010 mixes the EM solution evenly into the water, and finally sprays it onto the surface of the breeding bed by the nozzle 1005, where it comes into contact with the subsequent feed. The microbial community can quickly decompose organic matter into small molecules that are more easily absorbed by earthworms. Furthermore, the aeration of the bed soil through the pores 902 can improve the conversion efficiency of the microbial community.

[0036] An automatic feed-supplementing earthworm farming method, applicable to the aforementioned automatic feed-supplementing earthworm farming equipment, includes the following steps: S1: Feeding; The electric telescopic rod 805 drives the lifting plate 804 to move down and inserts the slotted plate 807 into the breeding bed. Then the vehicle body 1 moves, which can slot the surface of the breeding bed. Under the resistance of the soil, the tension spring 809 is stretched, and the slotted plate 807 moves towards the feed box 4. The connecting rod 815 drives the toothed plate 814 to move synchronously, which drives the second gear 813 to drive the valve ball 811 to rotate, which can open the feed pipe 810 and realize automatic feeding. S2: Oxygenation; When the second motor 803 drives the spiral blade 802 to rotate for feeding, it drives the rotating wheel 904 to rotate synchronously. The first protrusion 905 and the second protrusion 907 drive the piston 906 to move back and forth in the cylinder 903, so that the two one-way valves 909 are alternately opened, injecting air into the through groove 901 and into the breeding bed through the air hole 902, improving the ventilation of the breeding bed and increasing oxygen penetration; S3: Water replenishment; Water from the water tank 1001 is injected into the spray pipe 1004 by the water pump 1003 and sprayed onto the surface of the breeding bed by the nozzle 1005. At the same time, the fourth rotating shaft 1009 is driven to rotate by the third motor 1012, which drives the two extrusion blocks 1011 to rotate synchronously, injecting the EM solution from the solvent tank 1006 into the water outlet pipe 1002. The EM solution is evenly mixed into the water by the stirring rod 1010 and finally sprayed onto the surface of the breeding bed by the nozzle 1005, and comes into contact with the subsequent feed.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
