Description

Technical Field

[0001] The utility model relates to the technical field of soil restoration, in particular to a soil restoration agent spraying device. Background Art

[0002] After long-term cultivation, the land needs to be plowed to increase the activity of microorganisms in the soil and thus enhance soil fertility. If some soils are compacted or have decreased fertility, it is necessary to spray the soil with repair agents or activators in time for repair. By spraying the repair agent into the soil, the soil structure can be improved. The soil repair agent contains rich and high-value active bacteria. Improving soil fertility is one of the main steps in soil management. Most of the soil repair agent spraying equipment currently used still uses manual back-wearing water tanks for spraying. Due to the heavy weight of the water tank, if it is worn on the back for a long time for spraying, it will increase the work intensity of the workers and even cause long-term disease burden on the body. In addition, in the back-wearing spraying method, the spraying range of the repair agent mainly relies on manual operation, and the distance between the nozzle and the ground is large. On the one hand, the repair agent will evaporate in large quantities with the flow of air, and on the other hand, some of the repair agent will remain on the workers in large quantities. If protective equipment is not worn on the back, there will be safety hazards.

[0003] Patent CN219503003U proposes a soil remediation agent spraying device. Through the mutual cooperation among the bottom shell, water tank, hollow plate, spraying mechanism and driving mechanism, the distance between the nozzle and the ground is reduced, and the remediation agent can be fully sprayed into the soil, which can not only reduce the evaporation of the remediation agent, but also ensure the health of the workers. At the same time, the driving mechanism is used to drive the hollow plate to swing, which effectively expands the spraying area of ​​the soil and reduces the spraying stroke. Through the mutual cooperation among the bottom shell, guide wheel and moving mechanism, during the spraying process, the driving mechanism can be used to link and drive the movable wheel to move while the hollow plate swings, effectively solving the fatigue of traditional back-worn manual spraying, thereby improving the spraying efficiency and reducing the work intensity of workers.

[0004] In the above scheme, the hollow plate is driven to swing by a driving mechanism to spray the repair agent in a reciprocating manner. However, since the hollow plate and the nozzle are located at the outer end of the water tank in this technology, the overall length of the device is increased, and it will occupy a larger space when idle. In addition, the hollow plate and the spraying mechanism are damaged parts and are easily damaged by external force collision. Utility Model Content

The two sets of mounting plates can also be unfolded to a horizontal state, so as to spray the remediation agent on the soil within a longer horizontal range, thereby improving the spraying efficiency. In addition, the height of the mounting plate and the nozzle can be adjusted by the lifting assembly to avoid the spraying position being too far from the ground.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 4The utility model provides a technical solution: a soil remediation agent spraying device, comprising a storage box 1, wherein the storage box 1 stores a soil remediation agent mixture, and a storage tank 12 is provided at the bottom of the middle position of the storage box 1, wherein two groups of mounting plates 2 are symmetrically provided in the storage tank 12, and nozzles 21 are equidistantly installed on the surface of the mounting plates 2, and an expansion component 4 is provided at the top of the storage tank 12, wherein the expansion component 4 comprises a bidirectional screw rod 41, wherein the bidirectional screw rod 41 is provided at the top of the storage tank 12, and the two ends of the bidirectional screw rod 41 are meshed and sleeved with a mounting frame 45, and the top of the mounting plate 2 is connected to the mounting frame 45 through a bearing. The mounting frame 45 is rotatably connected, and lifting components 3 are provided on both sides of the bottom of the storage groove 12. The lifting components 3 include a horizontal plate 31, and an insertion rod 32 is slidably inserted inside the horizontal plate 31, and the outer end of the insertion rod 32 is rotatably connected to one side of the mounting plate 2 in the corresponding direction through a bearing. When using the device, the two groups of mounting plates 2 in the storage groove 12 are unfolded to a horizontal state through the unfolding component 4, and then the height of the mounting plate 2 and the nozzle 21 is adjusted through the lifting component 3, and the storage box 1 is pushed to move along the ground, and the repair agent is sprayed on the soil through the nozzle 21. After the spraying is completed, the mounting plate 2 is folded and retracted into the storage groove 12.

[0023] In this embodiment, moving wheels 11 are installed at the four corners of the storage box 1, a push frame 13 is fixed to the top of the rear end of the storage box 1, and injection ports 14 are opened on both sides of the storage groove 12 at the top of the storage box 1. Two hoses 22 are fixed on the inner wall of the storage groove 12 of the storage box 1, and the other end of the hose 22 is fixedly connected to the nozzle 21 on the mounting plate 2. The push frame 13 and the moving wheels 11 facilitate movement of the device, and the repair agent mixture is injected into the accommodating cavity of the storage box 1 on both sides of the storage groove 12 through the two injection ports 14, and is transported to the mounting plate 2 through the hose 22 and the water pump, and then sprayed through the nozzle 21. A certain length of the hose 22 needs to be reserved for the mounting plate 2 to be folded and unfolded.

[0024] In this embodiment, the unfolding component 4 also includes an extension plate 42, and the two ends of the bidirectional screw rod 41 are rotatably mounted with the extension plates 42 through bearings, and the outer ends of the extension plates 42 extend out of the storage slots 12 and are engaged with bolts 43. A spring telescopic rod 44 is fixed at the position of the two extension plates 42 on the top of the storage box 1, and the extended end of the spring telescopic rod 44 passes through the storage slots 12 and is fixed to the extension plate 42. When the extension plate 42 is pressed downward manually, the spring telescopic rod 44 extends and at the same time drives the mounting plate 2 to move downward through the mounting frame 45. Since the bottom of the mounting plate 2 is limited and guided by the insertion rod 32, the insertion rod 32 passes through the inside of the cross plate 31, and the mounting plate 2 is unfolded outward until it is horizontal, so as to spray the range on both sides of the storage box 1. By rotating the bidirectional screw rod 41, the horizontal spacing of the two mounting plates 2 can be adjusted.

[0025] In this embodiment, the lifting assembly 3 also includes a screw rod 34. The storage box 1 is located on the inner walls of both sides of the storage groove 12 and is meshed and inserted with the screw rod 34, and the bottom of the screw rod 34 is rotatably connected to the cross plate 31 through a bearing. The two groups of the insertion rods 32 have opposite directions of insertion. The outer ends of the insertion rods 32 are fixed with ear plates 33 corresponding to the positions of the screw rods 34, and the ear plates 33 are provided with screw holes. The bolts 43 can be meshed and inserted into the screw holes of the ear plates 33. After the two groups of mounting plates 2 are unfolded into a plane, the extension plates 42 and the ear plates 33 are locked by the bolts 43, and then the screw rods 34 are rotated. The screw rods 34 pass out along the upper end of the storage box 1, driving the cross plate 31, the mounting plate 2, the extension plate 42 and other structures to move vertically along the inside of the storage groove 12, adjust the spraying height, and avoid waste of the repair agent. When retracting the mounting plate 2, it is necessary to first unlock the bolts 43 and the ear plates 33.

[0026] When the device is used, when the extension plate 42 is pressed downward manually, the spring telescopic rod 44 extends, and at the same time, the mounting plate 2 is driven downward by the mounting frame 45. Since the bottom of the mounting plate 2 is limited and guided by the insertion rod 32, the insertion rod 32 passes through the inside of the horizontal plate 31, and the mounting plate 2 is expanded outward until it is horizontal, so as to spray the range on both sides of the storage box 1. By rotating the two-way screw rod 41, the horizontal spacing between the two mounting plates 2 can be adjusted, and the extension plate 42 and the ear plate 33 are locked by the bolt 43. Then, the screw rod 34 is rotated, and the screw rod 34 passes through the upper end of the storage box 1, driving the horizontal plate 31, the mounting plate 2, the extension plate 42 and other structures to move vertically along the inside of the storage slot 12, adjusting the spraying height, pushing the storage box 1 to move along the ground, and spraying the repair agent on the soil through the nozzle 21. After the spraying is completed, the mounting plate 2 is folded and retracted into the inside of the storage slot 12.
