Description

Technical Field

[0001] This utility model relates to the technical field of soil conditioner spraying equipment, specifically, to a soil conditioner spraying equipment. Background Technology

[0002] Chemical soil amendment refers to the process of applying chemical amendments to improve the physicochemical properties of acidic and alkaline soils (alkali soils). Commonly used chemical amendments include lime, gypsum, phosphogypsum, ferrous sulfate, sulfur, humic acid, and calcium humate. Applying chemical amendments can change the pH, soil solution, and the composition of bases in the soil absorbent complex. For example, applying lime to acidic soil can reduce soil acidity and facilitate the formation of soil structure; applying acidic substances to alkalized soil can lower the soil pH and alkalinity, which also plays an important role in improving soil structure. Soil amendments need to be sprayed through a spraying system.

[0003] For example, an existing Chinese authorized patent (publication number: CN221930645U) discloses a spraying device for soil conditioner, relating to the field of soil conditioner spraying equipment. This utility model includes a frame and a storage tank. Tires are rotatably connected to both sides and the bottom of the frame via axles. A stirring mechanism is provided on one side of the storage tank. By setting up the stirring mechanism, during spraying operations, the tires drive the frame to move. During the tire rotation, a first sprocket on the axle drives a second sprocket to rotate via a chain. The second sprocket then drives a magnetic block to rotate. As the magnetic block rotates, it drives a mounting base to rotate. The rotation principle is mainly due to the magnetic ring on the inner wall of the mounting base. When the magnetic block rotates, it pushes the magnetic ring to rotate through repulsion, effectively causing the transmission rod to rotate. The stirring blade then continuously and efficiently agitates the liquid in the inner chamber.

[0004] The above-designed spraying equipment for soil conditioners has the following drawbacks in actual use: the connection between the soil conditioner spraying pipe and the tee pipe on the cart lacks a stable structure, and the pipe may suddenly come off. Vibration during cart movement or pressure fluctuations in the pipeline may cause the tee joint to completely detach, requiring the machine to be stopped and reinstalled, thus reducing efficiency.

[0005] In view of this, a soil conditioner spraying device is provided to overcome the above-mentioned defects. Utility Model Content

[0028] Example

[0029] like Figure 1-4 As shown, a soil conditioner spraying device according to an embodiment of the present invention includes a mobile cart 1. A recessed frame 2 is provided on the left side of the top surface of the mobile cart 1. A first connecting port 3 is provided at the bottom of the inner cavity of the recessed frame 2. A driving mechanism 4 is symmetrically arranged on both sides of the inner cavity of the recessed frame 2. A plurality of guiding mechanisms 5 are respectively provided on both sides of the driving mechanism 4. A stabilizing mechanism 6 is provided on one side of the driving mechanism 4 and the guiding mechanism 5. A three-way pipe 7 is provided between the stabilizing mechanism 6 and the first connecting port 3. A spray pipe 8 is connected to both sides of the three-way pipe 7. A transmission pipe 9 is connected to the right side of the three-way pipe 7. A liquid supply mechanism 10 is connected to the right side of the transmission pipe 9.

[0030] In this embodiment, the three-way pipe 7 is initially installed in the first connector 3, with the right side connected to the transmission pipe 9 (for conveying soil conditioner), and the front and rear sides connected to the spray pipes 8 (for spraying conditioner). The stabilizing mechanism 6 is driven by the driving mechanism 4, moving downwards to press the three-way pipe 7. The bottom is provided with a structure that cooperates with the first connector 3 to ensure that the three-way pipe 7 is fixed. The two sides achieve stable vertical movement through the guide mechanism 5 (such as guide groove + slider). The connection between the three-way pipe 7 and the transmission pipe 9 enters the interface 19, and abuts against it. To prevent loosening, the water pump 21 draws modifier from the medicine storage tank 20 and delivers it to the transmission pipe 9 via the delivery pipe. The modifier is then diverted through the three-way pipe 7 to the front and rear spray pipes 8 for spraying. The three-way pipe 7 is simultaneously clamped by the first connecting port 3 and the stabilizing mechanism 6 to prevent shaking. The guide mechanism 5 ensures that the stabilizing mechanism 6 moves linearly to prevent deviation. The driving mechanism 4 provides controllable downward pressure to ensure that the clamping force is appropriate. The liquid supply mechanism 10 → delivery pipe → transmission pipe 9 → three-way pipe 7 → spray pipe 8 has a clear and sealed path.

[0031] Example

[0032] The driving mechanism 4 includes a driving groove 11, a lead screw 12, a driving block 13, and a servo motor 14. The driving groove 11 is carved into the left and right sides of the inner cavity of the recess 2. The lead screw 12 is installed at the bottom of the inner cavity of the driving groove 11. The outer wall of the lead screw 12 is connected to the driving block 13 by a reverse thread. The top of the lead screw 12 is connected to the servo motor 14. The driving groove 11 is located on the left and right sides of the inner cavity of the recess 2 and has a longitudinal groove structure, providing installation and movement space for the lead screw 12 and the driving block 13. The lead screw 12 is vertically fixed to the belt. The bottom of the moving groove 11 adopts a reverse thread (reverse thread) to ensure that the movement direction of the driving block 13 matches the rotation direction of the lead screw. It is connected to the output shaft of the servo motor 14 through a coupling or directly. The driving block 13 engages with the lead screw 12 through the embedded reverse thread nut, converting the rotational motion of the lead screw 12 into linear motion, which pushes the stabilizing mechanism 6 to move up and down. The servo motor 14 is fixed on the top of the recess 2 or on the external bracket. Its output shaft is connected to the lead screw 12 downward. It can be started / stopped by an external switch signal, and the speed and direction can be adjusted.

[0033] The guiding mechanism 5 includes a guide groove 15 and a guide block 16. The guide groove 15 is symmetrically excavated on the left and right sides of the inner cavity of the recess 2. The guide block 16 is slidably arranged in the guide groove 15. The guide groove 15 is symmetrically arranged on the left and right sides of the inner cavity of the recess 2 and is a vertical groove structure, providing a sliding track for the guide block 16 and restricting the direction of movement. The guide block 16 is embedded in the guide groove 15 and is in clearance fit with the groove wall (usually with lubricating or wear-resistant bushings). It is rigidly connected to the left and right sides of the stabilizing mechanism 6 (such as bolt fixing or integral molding).

[0034] The stabilizing mechanism 6 includes a stabilizing plate 17 and a second connecting port 18. The stabilizing plate 17 is disposed on one side of the guide plate and the driving plate. The second connecting port 18 is carved in the middle of the bottom surface of the stabilizing plate 17. The right side of the bottom of the recessed frame 2 and the right side of the bottom surface of the stabilizing plate 17 are both carved with connecting ports 19. The connection between the three-way pipe 7 and the transmission pipe 9 is disposed between the connecting ports 19. The stabilizing plate 17 is fixed on one side of the guide block 16 and the driving block 13, serving as a load-bearing structure to transmit the downward pressure of the driving mechanism 4 and evenly press the three-way pipe 7. The second connecting port 18 is disposed in the middle of the bottom surface of the stabilizing plate 17, corresponding vertically to the first connecting port 3, and cooperates with the first connecting port 3 to form a clamping space for the three-way pipe 7. The connecting ports 19 are respectively located on the right side of the bottom of the recessed frame 2 (fixed end) and the right side of the bottom surface of the stabilizing plate 17 (movable end). When the stabilizing plate 17 is pressed down, the two connecting ports 19 close, fixing the connection between the three-way pipe 7 and the transmission pipe 9 to prevent leakage.

[0035] The liquid supply mechanism 10 includes a storage tank 20 and a water pump 21. The storage tank 20 is mounted on the top surface of the mobile cart 1. The left side of the storage tank 20 is connected to the water pump 21 via a delivery pipe, and the water pump 21 is connected to the transmission pipe 9. The storage tank 20, fixed to the top surface of the mobile cart 1, serves as a storage container for the soil conditioner and is typically made of corrosion-resistant materials (such as polyethylene or stainless steel). Its capacity is designed according to operational requirements. The water pump 21 is located on the left side of the storage tank 20 and is connected to the storage tank via a delivery pipe and to the transmission pipe 9. The delivery pipe 9 is responsible for pumping the modifier into the spraying system. It can be an electric centrifugal pump or a peristaltic pump, depending on the viscosity and pressure requirements of the liquid. One-way valves are installed at the inlet and outlet of the water pump 21 to prevent backflow of liquid when the machine is stopped. The delivery pipe connects the outlet of the storage tank 20 to the inlet of the water pump 21. It is usually a flexible hose (such as PVC or silicone tubing). The transmission pipe 9 is used for the rigid pipe (such as PPR or stainless steel pipe) from the outlet of the water pump 21 to the tee 7. It must be pressure-resistant and leak-proof. All pipe joints are sealed with quick-release clamps or threaded seals to ensure no leakage under high pressure.

[0036] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the three-way pipe 7 is installed in the first connection port 3, and its right side is connected to the transmission pipe 9 (for conveying the modifier). Its front and rear sides are connected to the spray pipe 8 (for spraying the modifier). After the servo motor 14 is started, it drives the lead screw 12 to rotate. The reverse thread of the lead screw 12 causes the drive block 13 to move down, pushing the stabilizing plate 17 to press the three-way pipe 7. When the stabilizing plate 17 moves down, the guide blocks 16 on both sides of the stabilizing plate 17 slide along the guide groove 15 to ensure vertical movement stability. The three-way pipe 7 is clamped by the first connection port 3 and the second connection port 18 at the same time. The connection between the three-way pipe 7 and the transmission pipe 9 is located in the interface 19 (in the recess 2). The stabilizing plate 17 presses down to abut and limit the connection to prevent loosening or leakage. The water pump 21 draws the modifier from the medicine storage tank 20 through the delivery pipe. The modifier is sprayed out through the transmission pipe 9 → three-way pipe 7 → spray pipe 8.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
