[0002] As environmental pollution worsens, the discharge of various pollutants leads to increasingly poor soil properties. Coupled with excessive and frequent use, the soil is gradually becoming infertile. Therefore, it is necessary to improve the soil in a timely manner.

[0003] A search revealed Chinese Patent Publication No. CN205793998U, which discloses agricultural equipment for soil improvement, including a frame, a loosening shovel, a flipping device, a compaction roller, a pesticide tank, and a nozzle. The loosening shovel, flipping device, and compaction roller are all fixed below the frame in a front-to-back sequence. The pesticide tank is fixed on the frame. The nozzle inlet is connected to the pesticide tank, and the outlet is located between the loosening shovel and the flipping device. This technical solution requires manual adjustment of the nozzle position or replacement of different specifications of fixing brackets by loosening bolts one by one during use. It cannot achieve rapid and continuous width adjustment. The operation requires stopping the machine to disassemble and reassemble parts, consuming a lot of time and manpower, and seriously affecting operational efficiency. Therefore, this paper provides an agricultural equipment for soil improvement to solve the above problems. Utility Model Content

[0006] As a further improvement of this utility model: a connecting rotating hook is rotatably connected to the side of the main vehicle body, and a soil leveling brush is fixedly connected to the side of the main vehicle body.

[0007] As a further embodiment of this utility model: the inlet end of the liquid pump is penetrated through a hose to a position near the inner bottom wall of the fertilizer pipe, and the outlet end of the liquid pump is fixedly connected to and communicates with one end of the connecting hose.

[0008] As a further improvement of this utility model, the rotating shaft of the drive motor passes through the motor fixing bracket and is fixedly connected to the long threaded rod.

[0009] As a further improvement of this utility model: the guide through hole is adapted to the long guide rod, and the transverse strip slides on the outside of the two sets of long guide rods through the guide through hole.

[0010] As a further embodiment of this utility model: the number of sliding column guide grooves is the same as the number of transverse strips, and the sliding column guide groove extends from the top of the movable slotted plate to its bottom.

The embodiments of this utility model will be described below based on its overall structure.

[0022] Reference Figures 1 to 4In this embodiment of the present invention, an agricultural device for improving soil includes: a main body 1, a fertilizer pipe 4 fixedly connected to the top of the main body 1, a liquid pump 5 fixedly connected to the fertilizer pipe 4, a connecting hose 6 provided on the side of the liquid pump 5, the inlet end of the liquid pump 5 penetrating through the hose to a position near the inner bottom wall of the fertilizer pipe 4, the outlet end of the liquid pump 5 being fixedly connected to and communicating with one end of the connecting hose 6, a lower fixed bracket 7 fixedly connected to the bottom of the main body 1, a motor fixed bracket 8 fixedly connected to the side of the lower fixed bracket 7, a drive motor 9 fixedly connected to the outer side of the motor fixed bracket 8, a long threaded rod 10 rotatably connected to the inner side of the motor fixed bracket 8, the rotation shaft of the drive motor 9 passing through the motor fixed bracket 8 and fixedly connected to the long threaded rod 10, two sets of long guide rods 11 fixedly connected to the inner side of the lower fixed bracket 7, several sets of transverse strips 12 provided on the inner side of the lower fixed bracket 7, guide through holes 13 opened on the side of the transverse strips 12, the guide through holes 13 being connected to the long guide rods 11. Adapted, the transverse sliding bar 12 slides outside the two sets of long guide rods 11 through the guide through hole 13. A set of limiting sliding pins 14 are fixedly connected above each set of transverse sliding bars 12, and a set of fertilizer nozzles 15 are fixedly connected below each set of transverse sliding bars 12. A movable slotted plate 16 is slidably connected inside the lower fixed bracket 7. Several sets of fan-shaped sliding pin guide grooves 17 are opened above the movable slotted plate 16. The number of sliding pin guide grooves 17 is the same as the number of transverse sliding bars 12, and the sliding pin guide grooves 17 extend from the movable plate 11. The slotted plate 16 extends from its top to its bottom. The limiting sliding column 14 is adapted to the sliding column guide groove 17. Each set of limiting sliding columns 14 slides inside the corresponding sliding column guide groove 17. A movable plate connecting block 18 is fixedly connected above the movable slotted plate 16. The movable plate connecting block 18 has a threaded through hole adapted to the long threaded rod 10 on its inner side. One end of the connecting hose 6 is connected to the liquid outlet of the liquid pump 5. The other end of the connecting hose 6 is fixedly connected to the liquid equalization pipe of each set of fertilizer nozzles 15 and is in communication with it.

[0023] After the liquid pump 5 starts, it extracts the liquid fertilizer from the fertilizer pipe 4, pressurizes it, and delivers it to the equalization pipe through the connecting hose 6. Finally, it is sprayed downwards by multiple sets of fertilizer nozzles 15 to achieve fertilization. At the same time, the drive motor 9 rotates, causing the long threaded rod 10 connected to it to rotate. Since the moving plate connecting block 18 engages with the long threaded rod 10 through its threaded through hole, the rotation of the long threaded rod 10 will drive the moving plate connecting block 18 to move along the axial direction of the long threaded rod 10, thereby causing the moving slotted plate 16 fixed to it to slide inside the lower fixed bracket 7. When the moving slotted plate 16 slides, the sliding column guide groove 17 on it will be relative to the fixed bracket 7. The limiting slide pins 14 on the transverse strip 12 move. Because the slide pin guide groove 17 is fan-shaped, the movement of the moving slotted plate 16 forces each limiting slide pin 14 to slide in its respective slide pin guide groove 17, thereby pushing or pulling the transverse strip 12 connected to it to move in a direction parallel to the long guide rod 11, that is, to slide along the two sets of long guide rods 11. This synchronous movement of multiple sets of transverse strips 12 ultimately changes the distance between multiple sets of fertilizer nozzles 15, that is, adjusts the width of the fertilization operation. When the transverse strip 12 moves, the fertilizer nozzles 15 below it also move. The liquid supply of the nozzles is maintained through the connecting hose 6 and the liquid equalization pipe.

[0024] A connecting rotating hook 2 is rotatably connected to the side of the main vehicle body 1, and a soil leveling brush 3 is fixedly connected to the side of the main vehicle body 1.

[0025] When the main vehicle body 1 is towed, the soil leveling brush 3 fixed on its side will contact and brush the soil surface after the operation, scraping and smoothing the loose soil surface after trenching and fertilization, so as to achieve the effect of leveling the ground surface. The connecting rotating hook 2 is used to attach the equipment to the traction power (such as a tractor) and allow the equipment to have a certain degree of free rotation angle to adapt to the terrain during the operation.

[0026] The working principle of this utility model is as follows: The equipment is connected to a tractor or other traction power through a connecting rotating hook 2 on the side of the main vehicle body 1. The operator fills the fertilizer pipe 4 fixed above the main vehicle body 1 with liquid fertilizer and starts the liquid pump 5. The liquid pump 5 draws liquid fertilizer through the hose at its inlet end (the hose extends into the vicinity of the bottom of the inner cavity of the fertilizer pipe 4). After the liquid pump 5 pressurizes the fertilizer, it is output from its outlet end and transported through the connecting hose 6 to the equalization pipe connected to all fertilizer nozzles 15. Finally, the liquid fertilizer is evenly sprayed downward from multiple sets of fertilizer nozzles 15 fixed below the transverse strip 12 and applied to the soil.

[0027] The tractor pulls the main body 1 forward while the fertilizer nozzles 15 continuously spray fertilizer to complete the fertilization along the direction of travel. If it is necessary to adjust the fertilization operation width to adapt to different planting densities, that is, to change the distance between multiple sets of fertilizer nozzles 15, the drive motor 9 can be started. The drive motor 9 is fixed on the outside of the motor fixing bracket 8. Its rotating shaft drives the long threaded rod 10 fixed on the inside of the motor fixing bracket 8 to rotate. Since the movable plate connecting block 18 fixed above the movable slotted plate 16 has a threaded through hole that matches the long threaded rod 10, the rotation of the long threaded rod 10 will drive the movable plate connecting block 18 to move along the axial direction of the long threaded rod 10, thereby driving the movable slotted plate 16 to slide inside the lower fixing bracket 7.

[0028] When the movable slotted plate 16 slides, the fan-shaped sliding column guide groove 17 on it will move relative to the limiting sliding column 14 fixed above each transverse strip 12. Due to the special fan-shaped shape of the sliding column guide groove 17, the sliding of the movable slotted plate 16 forces all the limiting sliding columns 14 to move within their respective sliding column guide grooves 17, thereby pushing or pulling the connected transverse strip 12. The transverse strip 12 slides along the two sets of long guide rods 11 fixed to the inner side of the lower fixed bracket 7 through the guide through hole 13 on its side, thereby realizing that all fertilizer nozzles 15 converge inward or spread outward synchronously, completing the adjustment of the fertilization width. The connecting hose 6 and the flow equalization pipe are flexible pipes that can adapt to the movement of the fertilizer nozzles 15. During the journey, the soil leveling brush 3 fixed to the side of the main vehicle body 1 will brush over the soil surface after fertilization, scraping and smoothing the loose soil. At the same time, the connecting rotating hook 2 allows the main vehicle body 1 to rotate at a certain angle relative to the tractor to adapt to changes in terrain.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
