Description

Technical Field

[0001] This invention relates to the field of greening equipment technology, and more specifically to a device for applying a water-retaining agent to greening soil. Background Technology

[0002] Water-retaining agents are non-toxic and harmless high-molecular polymers that can absorb about four hundred times their own weight in water. They have the characteristics of rapid water absorption, slow release, and promotion of plant absorption. They can enhance the water and fertilizer retention capacity of soil and substrate, and improve the soil's aggregate structure. Generally, when carrying out greening planting, water-retaining agents need to be applied to the soil to improve the soil and prevent soil moisture loss.

[0003] Currently, water-retaining agents are generally applied manually. The agent is first spread on the soil surface, then tilled using tillage equipment to mix it into the soil, and finally watered before sowing.

[0004] The shortcomings of existing water-retaining agent application devices are that when applying existing water-retaining agents to the soil, the granular water-retaining agent needs to be spread on the surface first, and then the soil needs to be tilled to mix the water-retaining agent with the soil. In other words, it requires multiple steps to process the water-retaining agent, which cannot mix the water-retaining agent into the soil at one time, resulting in low application efficiency and affecting the overall greening and sowing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a device for applying water-retaining agents to greening soil, so as to solve the technical problem that the application of water-retaining agents in the prior art requires multiple steps to mix the water-retaining agent into the soil, resulting in low application efficiency and affecting the efficiency of greening sowing.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A device for applying a water-retaining agent to greening soil includes a truck bed, the bottom of which is rotatably equipped with wheels, and further includes:

[0008] A water-retaining agent conveying assembly includes a water-retaining agent storage tank and a lifting guide cylinder. The water-retaining agent storage tank is mounted on a truck bed. The storage tank contains a water-retaining agent storage cavity and a movable cavity. A partition plate separates the storage cavity and the movable cavity, and a connecting port is located at the bottom of the partition plate. A pusher / rotor that rotatably connects to a wheel is located at the connecting port. A sealing plate is located on the side of the connecting port closest to the movable cavity. The lifting guide cylinder is slidably mounted at the bottom of the movable cavity. A linkage gear assembly connects the lifting guide cylinder and the sealing plate. An auxiliary guiding assembly that connects to the lifting guide cylinder is located at the bottom of the water-retaining agent storage cavity.

[0009] A hydraulic telescopic rod is vertically fixed to the truck bed. The telescopic end of the hydraulic telescopic rod is connected to a crossbar connected to a lifting guide cylinder, and a soil turning component is provided below the crossbar.

[0010] A water conveying assembly is installed on the truck bed, and the water outlet of the water conveying assembly is connected to the bottom of the lifting guide cylinder.

[0011] As a further aspect of the present invention: the soil turning assembly includes an inclined guide tube, hook teeth, and a rotary tiller. Multiple inclined guide tubes are provided and are equidistantly distributed on one side of the bottom of the lifting guide cylinder, and each inclined guide tube is connected to the bottom of the lifting guide cylinder. Multiple hook teeth are provided and are correspondingly connected to the bottom end of the inclined guide tubes. The rotary tiller is rotatably disposed at the end of the crossbeam away from the lifting guide cylinder.

[0012] As a further embodiment of the present invention: the linkage gear assembly includes a first rack, a second rack, and a transition gear. The first rack is vertically connected to the top of the lifting guide cylinder, the second rack is disposed on the top of the sealing slide plate, and the transition gear is disposed between the first rack and the second rack, with both the first rack and the second rack meshing with the transition gear. The transition gear is rotatably connected to the inner wall of the movable cavity via a rotating shaft.

[0013] As a further embodiment of the present invention: the auxiliary material guiding assembly includes a flap and a traction rope. The flap is disposed at the bottom of the water-retaining agent storage cavity, and one end of the flap near the material pushing component is movably connected to the bottom surface of the water-retaining agent storage cavity via a hinge. One end of the traction rope is connected to the flap away from the material pushing component, and the other end passes through the top of the water-retaining agent storage box and is connected to the top of the lifting guide cylinder.

[0014] As a further aspect of the present invention: the top of the water-retaining agent storage box is provided with a fixed pulley that cooperates with the traction rope.

[0015] As a further aspect of the present invention: the pusher includes a rotating column, which is horizontally rotatably disposed at the communication port between the water-retaining agent storage cavity and the active cavity, and blades are distributed circumferentially on the outer wall of the rotating column, and a synchronous belt assembly is disposed between the rotating column and the wheel.

[0016] As a further embodiment of the present invention: the synchronous belt assembly includes a drive wheel and a drive belt, the drive wheel is provided in two sets, one set of the drive wheel is coaxially connected to the rotating column, and the other set of the drive wheel is coaxially connected to the wheel, and the drive belt is connected between the two sets of the drive wheel.

[0017] As a further embodiment of the present invention: the water conveying assembly includes a water tank, a water pump and a corrugated telescopic water pipe. The water tank is connected to the truck bed, the water pump is installed inside the water tank, the truck bed is provided with a connecting water pipe, one end of the connecting water pipe is connected to the outlet end of the water pump, and the other end is connected to the corrugated telescopic water pipe. The bottom end of the corrugated telescopic water pipe is connected to the bottom of the lifting guide cylinder.

[0018] The beneficial effects of this invention are:

[0019] 1. When the truck bed of this invention moves along the ground, the hydraulic telescopic rod drives the hook teeth and rotary tiller to descend and cut into the soil for tilling. At the same time, the lifting guide cylinder, which is set in conjunction with the water-retaining agent storage tank, also descends synchronously. During the descent of the lifting guide cylinder, the lifting guide cylinder is pulled up by the traction rope to guide the water-retaining agent to slide towards the rotating column of the pusher. At the same time, the lifting guide cylinder also drives the sealing plate to rise through the linkage gear assembly, so as to open the connection port. Thus, when the wheels of the truck bed roll along the ground, the wheels drive the rotating column to rotate synchronously through the synchronous belt assembly, pushing the water-retaining agent into the lifting guide cylinder. Finally, it is discharged into the soil through the distributed inclined guide tubes, which facilitates effective mixing with the soil. In this process, the water-retaining agent is spread and the tilling is carried out simultaneously, improving the application efficiency.

[0020] 2. When the hydraulic telescopic rod of the present invention drives the hook teeth and rotary tiller to descend, the hook teeth scrape out grooves on the ground. Since the hook teeth are connected to the end of the inclined guide tube, the water-retaining agent that slides out along the inclined guide tube falls into the scraped grooves. Then the rotary tiller breaks up and turns the soil so that the water-retaining agent can be effectively mixed with the soil.

[0021] 3. When the hydraulic telescopic rod of the present invention is in the retracted state, the lifting guide cylinder is inserted into the movable cavity inside the water-retaining agent storage tank, and at this time the sealing plate blocks the connection port. In this way, even if the wheel rolls along the ground and drives the rotating column to rotate, the water-retaining agent can be prevented from being discharged. Attached Figure Description

[0029] 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, and 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.

[0030] like Figures 1-5 As shown, a soil water-retaining agent application device for greening is used to apply a water-retaining agent to the soil. The water-retaining agent is a non-toxic and harmless polymer that can absorb about four hundred times its own weight in water. It is generally in granular form. The device includes a bucket 1 with a movable connecting joint at one end. The bucket 1 is connected to the drive head end through the movable connecting joint, and the drive head pulls the bucket 1 to move. Wheels 2 are rotatably installed at the bottom of the bucket 1. The device also includes a water-retaining agent delivery component, a hydraulic telescopic rod 10, a soil turning component, and a water delivery component.

[0031] The water-retaining agent conveying assembly includes a water-retaining agent storage tank 13 and a lifting guide cylinder 12. The water-retaining agent storage tank 13 is mounted on the truck bed 1. The interior of the water-retaining agent storage tank 13 contains a water-retaining agent storage cavity 16 and a movable cavity 17. A partition plate 26 is provided between the water-retaining agent storage cavity 16 and the movable cavity 17, and a connecting port is provided at the bottom of the partition plate 26. A pusher rotor, which is rotatably connected to a wheel 2, is provided at the connecting port. When the wheel 2 rolls along the ground, the pusher rotor rotates synchronously, facilitating the flow of water-retaining agent from the water-retaining agent storage cavity 16 into the movable cavity 17. A sealing slide plate 18 is provided on the side of the connecting port near the movable cavity 17. It should be noted that a limiting groove is provided on the inner wall of the movable cavity 17, which slides smoothly with the sealing slide plate 18, facilitating the smooth up and down sliding of the sealing slide plate 18. The lifting guide cylinder 12 is slidably disposed at the bottom of the movable cavity 17 and passes through the bottom of the water-retaining agent storage box 13. A linkage gear assembly is provided between the lifting guide cylinder 12 and the sealing plate 18. When the lifting guide cylinder 12 slides up and down, the linkage gear assembly can drive the sealing plate 18 to slide in the opposite direction synchronously. Before the lifting guide cylinder 12 descends, the sealing plate 18 blocks the connection port to prevent the water-retaining agent from being pushed out. When it is necessary to sprinkle the water-retaining agent on the ground, the lifting guide cylinder 12 is lowered, and the top of the lifting guide cylinder 12 is lowered to a position lower than the pusher. At this time, the lifting guide cylinder 12 drives the sealing plate 18 to rise through the linkage gear assembly. The rotating pusher pushes the water-retaining agent to slide down to the top of the lifting guide cylinder 12, making it easier for the water-retaining agent to enter the lifting guide cylinder 12.

[0032] An auxiliary material guiding component is provided at the bottom of the water-retaining agent storage cavity 16 and is connected to the lifting guide cylinder 12. When the lifting guide cylinder 12 slides down, the auxiliary material guiding component helps the water-retaining agent in the water-retaining agent storage cavity 16 to flow to the position of the pusher and transfer piece, which facilitates the discharge.

[0033] The hydraulic telescopic rod 10 is vertically fixed to the truck bed 1, with the telescopic end of the hydraulic telescopic rod 10 facing downwards. The telescopic end of the hydraulic telescopic rod 10 is fixedly connected to a crossbeam 11 connected to the lifting guide cylinder 12, and a soil turning component is provided below the crossbeam 11. When it is necessary to spread the water-retaining agent into the soil, the hydraulic telescopic rod 10 is controlled to extend. The hydraulic telescopic rod 10 then drives the lifting guide cylinder 12 and the soil turning component to descend through the crossbeam 11. In this way, the soil turning component breaks up and turns over the ground soil, making it easier for the water-retaining agent to mix into the soil.

[0034] The water conveying component is installed on the truck bed 1, and the water outlet of the water conveying component is connected to the bottom of the lifting guide cylinder 12. The water conveying component is used to guide water into the lifting guide cylinder 12, which facilitates watering while applying water-retaining agent, and can also rely on water flow to assist in conveying water-retaining agent.

[0035] In some specific implementations, the tilling assembly includes inclined guide tubes 7, hook teeth 8, and rotary tillers 9. Multiple inclined guide tubes 7 are provided and equidistantly distributed on one side of the bottom of the lifting guide cylinder 12, and each inclined guide tube 7 is connected to the bottom of the lifting guide cylinder 12. The water-retaining agent entering the lifting guide cylinder 12 is guided out through each inclined guide tube 7. Multiple hook teeth 8 are provided and correspondingly connected to the bottom end of the inclined guide tubes 7. The rotary tiller 9 is rotatably mounted at the end of the crossbeam 11 away from the lifting guide cylinder 12. The rotary tiller 9 is driven to rotate by a motor. When the hydraulic telescopic rod 10 extends, the rotary tiller 9 moves downwards... After the blades are lowered into the soil, the motor is started manually. The motor drives the rotary tiller 9 to rotate. The rotary tiller 9 uses a ring of cutting blades to break up the soil and turn it over. In this way, the water-retaining agent discharged through the inclined guide tube 7 mixes with the soil. It should be noted that as the bucket 1 moves forward, the hook teeth 8 are in front of the rotary tiller 9. The hook teeth 8 first scrapes the ground to make furrows, so that the discharged water-retaining agent can fall into the furrows. Then, the rotary tiller 9 breaks up and turns the soil to promote the mixing of the water-retaining agent with the soil.

[0036] In some specific embodiments, the linkage gear assembly includes a first rack 22, a second rack 20, and a transition gear 21. The first rack 22 is vertically connected to the top of the lifting guide cylinder 12, the second rack 20 is disposed on the top of the sealing slide plate 18, and the transition gear 21 is disposed between the first rack 22 and the second rack 20. Both the first rack 22 and the second rack 20 mesh with the transition gear 21. The transition gear 21 is rotatably connected to the inner wall of the movable cavity 17 via a rotating shaft.

[0037] When the hydraulic telescopic rod 10 is in the retracted state, the lifting guide cylinder 12 is inserted into the movable cavity 17. At this time, the sealing plate 18 seals the connection between the water-retaining agent storage cavity 16 and the movable cavity 17. When the hydraulic telescopic rod 10 extends, the lifting guide cylinder 12 descends. At this time, the lifting guide cylinder 12 drives the first rack 22 to descend, and the first rack 22 drives the transition gear 21 to rotate clockwise. Then the transition gear 21 drives the second rack 20 to rise. In this way, the second rack 20 drives the sealing plate 18 to rise, so that the connection is opened.

[0038] In some specific implementations, the auxiliary material guiding assembly includes a flap 14 and a traction rope 15. The flap 14 is located at the bottom of the water-retaining agent storage cavity 16, and one end of the flap 14 near the pusher is movably connected to the bottom surface of the water-retaining agent storage cavity 16 via a hinge. One end of the traction rope 15 is connected to the flap 14 away from the pusher, and the other end passes through the top of the water-retaining agent storage box 13 and into the movable cavity 17, and then connects to the top of the lifting guide cylinder 12. The top of the water-retaining agent storage box 13 is provided with a fixed pulley 25 that cooperates with the traction rope 15.

[0039] When the lifting guide cylinder 12 descends, it pulls the traction rope 15. The traction rope 15 pulls up the flap 14 through the steering action of the fixed pulley 25, so that the flap 14 is rotated to the tilted position. In this way, the flap 14 can easily guide the water-retaining agent in the water-retaining agent storage cavity 16 to the position of the pusher, thus making it easier to push out.

[0040] In some specific implementations, the pusher includes a rotating column 19, which is horizontally rotatably disposed at the communication port between the water-retaining agent storage cavity 16 and the movable cavity 17. The outer wall of the rotating column 19 is circumferentially distributed with blades. A synchronous belt assembly is provided between the rotating column 19 and the wheel 2, which enables the rotating column 19 and the wheel 2 to rotate synchronously.

[0041] The aforementioned synchronous belt assembly includes a drive pulley 23 and a drive belt 24. There are two sets of drive pulleys 23. One set of drive pulleys 23 is coaxially connected to the rotating column 19, and the other set of drive pulleys 23 is coaxially connected to the wheel 2. The drive belt 24 is connected between the two sets of drive pulleys 23. When the wheel 2 rolls along the ground, the corresponding set of drive pulleys 23 rotates, and then drives the other set of drive pulleys 23 to rotate through the drive belt 24. In this way, the rotating column 19 rotates synchronously with the wheel 2 without the need for additional drive.

[0042] In some specific implementations, the water conveying assembly includes a water tank 3, a water pump 4, and a corrugated telescopic water pipe 6. The water tank 3 is connected to the truck bed 1, the water pump 4 is installed inside the water tank 3, and a battery pack that powers the water pump 4 is installed on the truck bed 1. The battery pack can also power the motor connected to the rotary tiller 9. A connecting water pipe 5 is buried in the truck bed 1. One end of the connecting water pipe 5 is connected to the water outlet of the water pump 4, and the other end is connected to the corrugated telescopic water pipe 6. The bottom end of the corrugated telescopic water pipe 6 is connected to the bottom of the lifting guide cylinder 12.

[0043] When applying the water-retaining agent, manually start the water pump 4. The water pump 4 will draw water out of the water tank 3 and then guide it into the lifting guide cylinder 12 through the connecting water pipe 5 and the corrugated telescopic water pipe 6. Since the corrugated telescopic water pipe 6 is telescopic, the lifting guide cylinder 12 can be raised and lowered normally.

[0044] To facilitate understanding of this solution by those skilled in the art, the principles of this solution are briefly explained below in conjunction with practical application scenarios:

[0045] First, the truck bed 1 is moved to the green area where water-retaining agent needs to be applied, relying on the truck to traction the truck bed 1. During the normal movement, the hydraulic telescopic rod 10 is in the retracted state. At this time, the lifting guide cylinder 12 is inserted into the movable cavity 17, and the sealing plate 18 blocks the connection between the water-retaining agent storage cavity 16 and the movable cavity 17. Even if the wheel 2 drives the rotating column 19 to rotate synchronously through the transmission wheel 23 and the transmission belt 24, it can prevent the water-retaining agent from being pushed out.

[0046] When water-retaining agent needs to be applied, the hydraulic telescopic rod 10 is extended and the motor connected to the rotary tiller 9 is started. In this way, the rotary tiller 9 and the hook tooth 8 descend and cut into the soil, while the lifting guide cylinder 12 also slides down as the telescopic end of the hydraulic telescopic rod 10 extends.

[0047] When the lifting guide cylinder 12 slides down, it drives the first rack 22 to descend. The first rack 22 then drives the transition gear 21 to rotate clockwise. Then the transition gear 21 drives the second rack 20 to rise. In this way, the second rack 20 drives the sealing slide plate 18 to rise, so that the communication port is opened. At the same time, the top of the lifting guide cylinder 12 descends to a position lower than the rotating column 19. Thus, as the truck bed 1 moves forward, the rotating column 19 rotates synchronously with the wheel 2, which facilitates the pushing of the water-retaining agent in the water-retaining agent storage chamber 16 into the lifting guide cylinder 12.

[0048] Furthermore, during the descent of the lifting guide cylinder 12, the traction rope 15 is pulled. The traction rope 15 is turned by the fixed pulley 25 and pulls up the flap 14, so that the flap 14 is turned to the tilted position. In this way, the flap 14 can easily guide the water-retaining agent in the water-retaining agent storage cavity 16 to the position of the rotating column 19. The rotating column 19 can easily push the water-retaining agent into the lifting guide cylinder 12. The water-retaining agent that enters the lifting guide cylinder 12 is guided to slide out through each inclined guide tube 7.

[0049] As the truck bed 1 moves forward, the hook teeth 8 are positioned in front of the rotary tiller 9. The hook teeth 8 first scrape out grooves in the ground, allowing the water-retaining agent to fall into the grooves. The rotary tiller 9 rotates, using a ring of cutting blades to break up the soil and simultaneously turn it over. In this way, the water-retaining agent discharged through the inclined guide tube 7 mixes with the soil. The water pump 4 draws water from the water tank 3 and then guides it into the lifting guide tube 12 through the connecting water pipe 5 and the corrugated telescopic water pipe 6. This facilitates watering while applying the water-retaining agent, and the water flow can also assist in transporting the water-retaining agent.

[0050] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
