Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil improvement equipment technology, specifically to an acidified soil improvement equipment. Background Technology
[0002] Soil acidification refers to the phenomenon of decreased soil pH and increased acidity, which is often caused by a combination of factors such as intensive farming, excessive use of chemical fertilizers, and acid deposition. Acidified soil damages soil structure, reduces soil fertility, affects microbial activity, and thus threatens crop growth, leading to reduced crop yields or even crop failure.
[0003] A common method for addressing soil acidification is to spray saturated quicklime solution. Currently, when spraying saturated quicklime solution, the nozzle is attached to the plow head, allowing the saturated quicklime solution to be sprayed directly into the trench while the plow breaks up the soil, ensuring that the liquid quickly penetrates into the soil.
[0004] However, since the nozzles are mounted on the plow head, the soil may come into contact with the nozzles when the plow turns the soil, causing them to become clogged. In addition, solid particles in the saturated lime solution may also clog the nozzles if they are not fully dissolved or filtered, resulting in uneven spraying and reduced improvement effect. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an acidified soil improvement device, including a traction plate. Multiple harrows are mounted on the lower surface of the traction plate along its length. Each harrow has a nozzle on its head, with spray holes on both outer surfaces and the bottom. A spraying mechanism is mounted on the upper surface of the traction plate to inject saturated quicklime solution into the nozzle. A ball A is mounted in the center of the nozzle via an elastic lifting mechanism. A top rod B is mounted at the bottom of ball A, and the top rod B is coaxially aligned with the spray hole at the bottom of the nozzle. Two sets of top rods A are symmetrically arranged inside the nozzle via an elastic reset mechanism. The top rods A are coaxially aligned with the spray holes on the side wall of the nozzle, with one end of each top rod A equidistant from the spray hole on the side wall, and the other end of each top rod A equidistant from the axis of top rod B. A ball B is mounted at the other end of each top rod A. A pressing mechanism is provided on the outer surface of the traction plate, which cooperates with the elastic lifting mechanism during harrowing.
[0006] Preferably, the spraying mechanism includes a storage tank mounted on the upper surface of the traction plate, a water pump mounted on the top of the storage tank, the pump's extraction end extending into the interior of the storage tank, an outlet pipe connected to the pump's output end, a horizontal pipe mounted on the side surface of the traction plate, the end of the outlet pipe connected to the horizontal pipe, multiple branch pipes connected along the length of the horizontal pipe's outer surface, an inlet pipe connected to the outer surface of the nozzle, the end of the inlet pipe connected to the plow head of the plow, and the ends of the branch pipes connected to the inlet pipe.
[0007] Preferably, the elastic lifting mechanism includes a guide rod that vertically penetrates the interior of the nozzle, the bottom of the guide rod is connected to the ball A, the top of the guide rod is fitted with a squeezing block, and a spring A is sleeved on the outer surface of the guide rod, with the two ends of the spring A abutting against the nozzle and the squeezing block respectively.
[0008] Preferably, the extrusion mechanism includes two brackets mounted on the outer surface of the traction plate, a rotating shaft rotatably mounted between the two brackets, movable wheels mounted at both ends of the rotating shaft, and multiple cams mounted on the outer surface of the rotating shaft, with the cams engaging in extrusion with the extrusion block.
[0009] Preferably, the elastic reset mechanism includes a mounting base installed on the inner wall of the nozzle, a slide rod installed inside the mounting base, a slider slidably mounted on the outer surface of the slide rod, and a top rod A connected to the slider. A spring B is sleeved on the outer surface of the slide rod, and the two ends of the spring B abut against the inner wall of the mounting base and the slider, respectively.
[0010] Preferably, a stirring motor is installed on the top of the storage tank, and the output shaft of the stirring motor passes through the storage tank and is fitted with a stirring shaft.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] (1) By setting the nozzle to a cone-shaped structure, which is similar to the cross-sectional structure of the trench plowed by the plow, and by opening spray holes on both sides and the bottom, the sprayed saturated lime liquid can adhere to the entire inner wall of the trench, thereby improving the coverage and uniformity of the saturated lime liquid and thus improving the improvement effect.
[0013] (2) By using the elastic lifting mechanism, the squeezing mechanism and the elastic reset mechanism in combination, this utility model can drive the ball A to move up and down during the plowing process. When the ball A moves up and down, it squeezes each ball B in turn, which can drive the top rod A and the top rod B to be inserted into the spray hole to clear the blocked spray hole, avoid blockage, and ensure the uniformity of the spraying range of saturated lime liquid.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 5 As shown, an acidified soil improvement device includes a traction plate 100, a plow 101, a nozzle 102, a spray hole 103, a ball A104, a top rod A105, a ball B106, a top rod B107, a spraying mechanism 200, a storage tank 201, a water pump 202, an outlet pipe 203, a horizontal pipe 204, an inlet pipe 205, a diversion pipe 206, an elastic lifting mechanism 300, a guide rod 301, a pressing block 302, a spring A303, a pressing mechanism 400, a bracket 401, a rotating shaft 402, a moving wheel 403, a cam 404, an elastic reset mechanism 500, a mounting base 501, a sliding rod 502, a slider 503, a spring B504, and a stirring motor 600.
[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] like Figures 1 to 5As shown, multiple harrows 101 are installed on the lower surface of the traction plate 100 along its length. The harrows 101 are equipped with nozzles 102 on their heads. Spray holes 103 are provided on both sides of the outer surface and the bottom of the nozzles 102. A spraying mechanism 200 is provided on the upper surface of the traction plate 100. The spraying mechanism 200 is used to inject saturated quicklime solution into the nozzles 102. By connecting the traction plate 100 to a traction device, such as a tractor, the harrows 101 can be driven to turn over the soil. After the soil is turned over, the spraying mechanism 200 can directly and accurately spray the saturated quicklime solution into the trench. A ball A104 is installed in the middle of the nozzle 102 via an elastic lifting mechanism 300. A top rod B107 is installed at the bottom of the ball A104. The top rod B107 is coaxially arranged with the nozzle hole 103 at the bottom of the nozzle 102. When the elastic lifting mechanism 300 drives the ball A104 to the lowest position, it can drive the top rod B107 to insert into the nozzle hole 103 at the bottom for unblocking. Inside the nozzle 102, two sets of push rods A105 are symmetrically arranged via an elastic reset mechanism 500. The push rods A105 are coaxially aligned with the nozzle holes 103 on the side wall of the nozzle 102, with one end of each push rod A105 equidistant from the nozzle hole 103 on the side wall, and the other end of each push rod A105 equidistant from the axis of push rod B107. A ball B106 is mounted on the other end of each push rod A105. During the raising and lowering of the ball A104, the ball A104 compresses the ball B106, thereby driving the push rod A105 to clear the nozzle holes 103 on the side wall. A compression mechanism 400 is provided on the outer surface of the traction plate 100. The compression mechanism 400 cooperates with the elastic lifting mechanism 300 when the plow 101 plows the land, automatically causing the ball A104 to reciprocate up and down during the plowing process, thus clearing the nozzle holes 103.
[0024] A stirring motor 600 is installed on the top of the storage tank 201. The output shaft of the stirring motor 600 passes through the storage tank 201 and is equipped with a stirring shaft. The stirring motor 600 drives the stirring shaft to stir the saturated quicklime solution, thereby reducing the possibility of solid particles in the saturated quicklime solution not being fully dissolved and causing blockage of the spray nozzle 103.
[0025] The spraying mechanism 200 includes a liquid storage tank 201 mounted on the upper surface of the traction plate 100. A water pump 202 is mounted on the top of the liquid storage tank 201, with the extraction end of the water pump 202 extending into the interior of the liquid storage tank 201. The output end of the water pump 202 is connected to an outlet pipe 203. A horizontal pipe 204 is mounted on the side surface of the traction plate 100, with the end of the outlet pipe 203 connected to the horizontal pipe 204. Multiple branch pipes 20 are connected along the length of the outer surface of the horizontal pipe 204. 6. The outer surface of the nozzle 102 is connected to the liquid inlet pipe 205. The end of the liquid inlet pipe 205 is connected to the plow head of the rake 101, and the end of the diversion pipe 206 is connected to the liquid inlet pipe 205. When the water pump 202 is started, it draws the saturated lime solution from the storage tank 201 and enters the nozzle 102 through the liquid outlet pipe 203, the horizontal pipe 204 and the liquid inlet pipe 205. Then it is sprayed outward from the spray hole 103 to achieve the purpose of spraying the inner wall of the trench.
[0026] The elastic lifting mechanism 300 includes a guide rod 301 that vertically penetrates the interior of the nozzle 102. The bottom of the guide rod 301 is connected to the ball A104, and a squeezing block 302 is installed on the top of the guide rod 301. A spring A303 is sleeved on the outer surface of the guide rod 301. The two ends of the spring A303 abut against the nozzle 102 and the squeezing block 302, respectively. When the squeezing block 302 is pressed down, the ball A104 can be moved downward. When the ball A104 contacts and squeezes the ball B106, the top rod A105 can be moved and inserted into the spray hole 103 on the side wall to achieve the purpose of unblocking. When the ball A104 descends to the lowest point, the top rod B107 can be inserted into the bottom spray hole 103 to unblock, thereby avoiding blockage and ensuring the improvement effect. Furthermore, since sphere A104 can only compress sphere B106 at the same height each time, it can clear blockages without affecting the normal spraying of saturated quicklime solution, resulting in good performance.
[0027] The extrusion mechanism 400 includes two supports 401 mounted on the outer surface of the traction plate 100. A rotating shaft 402 is rotatably mounted between the two supports 401. Both ends of the rotating shaft 402 are equipped with movable wheels 403. Multiple cams 404 are mounted on the outer surface of the rotating shaft 402, and the cams 404 are in a pressing engagement with the extrusion block 302. When the traction device drives the traction plate 100 to move, causing the plow 101 to break the soil, the movable wheels 403 will support and roll on the ground, thereby driving the rotating shaft 402 to rotate. The rotating shaft 402 drives the cams 404 to press the extrusion block 302, so that every time the rotating shaft 402 rotates once, it will drive the ball A104 to complete one lifting and lowering. The high frequency of unblocking the nozzle 103 can significantly reduce the time when the nozzle 103 becomes blocked and reduce the impact.
[0028] The elastic reset mechanism 500 includes a mounting base 501 installed on the inner wall of the nozzle 102. A slide rod 502 is installed inside the mounting base 501. A slider 503 is slidably installed on the outer surface of the slide rod 502. A top rod A105 is connected to the slider 503. A spring B504 is sleeved on the outer surface of the slide rod 502. The two ends of the spring B504 abut against the inner wall of the mounting base 501 and the slider 503, respectively. When the ball B106 is squeezed by the ball A104, the ball B106 drives the top rod A105 to move. The top rod A105 drives the slider 503 to slide on the slide rod 502 and compress the spring B504. When the ball A104 separates from the ball B106, the compressed spring B504 releases its elastic force to push the top rod A105 to reset, so that the ball A104 can drive the top rod A105 to clear the nozzle 103 with each rise and fall.
[0029] The working principle of this utility model is as follows:
[0030] In use, the towing plate 100 is connected to a towing device, such as a tractor. The towing device drives the plow 101 to turn over the soil. After the soil is turned over, the water pump 202 draws saturated quicklime solution from the storage tank 201 and enters the nozzle 102 through the outlet pipe 203, the horizontal pipe 204, and the inlet pipe 205. Then, it is sprayed outward from the spray hole 103 to achieve the purpose of spraying the inner wall of the trench. During the movement of the towing plate 100, the moving wheel 403 will support and roll on the ground. The rotating shaft 402 rotates, and the rotating shaft 402 drives the cam 404 to squeeze the extrusion block 302, causing the extrusion block 302 to move the ball A104 downward. When the ball A104 contacts and squeezes the ball B106, it can drive the push rod A105 to move and insert into the spray hole 103 on the side wall to achieve the purpose of unblocking. When the ball A104 descends to the lowest point, it can drive the push rod B107 to insert into the spray hole 103 at the bottom to unblock, thereby avoiding blockage and ensuring the improvement effect.
