Description

Technical Field

[0001] This utility model specifically relates to a fertilizer application device for vegetable greenhouses, belonging to the technical field of fertilizer application devices. Background Technology

[0002] The fertilization device for vegetable greenhouses is an intelligent agricultural device that integrates multiple functions such as precision irrigation, fertilization, and soil turning. It aims to provide efficient and reasonable water and fertilizer management and soil treatment according to the needs of different growth stages of vegetables, thereby improving crop yield and quality and optimizing the agricultural production process.

[0003] Chinese Patent (Publication No.: CN220023526U) discloses a fertilization device for greenhouse vegetable cultivation, including a base plate. A mixing tank is fixedly connected to the top of the base plate. A water tank is fixedly connected to the top left side of the mixing tank. A water outlet pipe is fixedly connected to the front right side of the water tank. A motor is installed on the right side of the water tank. A second rotating rod is fixedly connected to the output end of the motor. Mixing blades are evenly fixedly connected to the outer side of the second rotating rod. Water pumps are fixedly connected to the front and rear of the top of the mixing tank. A water pump input pipe is fixedly connected to the input end of the water pump, and a water delivery pipe is fixedly connected to the output end of the water pump. This utility model, through the cooperation of the mounting frame, double-headed motor, first rotating rod, and soil-turning shovel, achieves efficient fertilization of greenhouse vegetables, reducing the human resource consumption during the fertilization process.

[0004] The aforementioned fertilization device for greenhouse vegetable cultivation has a rigid connection structure between its soil-turning shovel and rotating rod. If it encounters hard obstacles such as large rocks hidden in the soil during operation, due to the lack of stress release or avoidance buffer mechanism, it will generate repeated impact loads when the vehicle continues to move, causing the shovel body to undergo plastic deformation or even breakage and failure. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a fertilization device for vegetable greenhouses. The device includes a vehicle body with a support frame installed at the rear end. One end of the support frame is connected to a soil-turning frame, and a crossbeam is connected to the bottom of the soil-turning frame. Multiple sets of connecting frames are mounted on the crossbeam. One end of each connecting frame is rotatably connected to a rotating plate via a pivot. A soil-turning plow is installed at one end of the rotating plate. A limiting frame for limiting the rotation range of the rotating plate is installed on one side of the connecting frame. A bracket is connected to one side of the connecting frame, and an adjusting cylinder is installed at the other end of the bracket. A first sliding plate and a second sliding plate are slidably connected to the two ends of the adjusting cylinder, respectively. A spring is provided between the first and second sliding plates. A first screw threaded through the interior of the adjusting cylinder is rotatably connected to one end of the first sliding plate, and a push rod slidably through the interior of the adjusting cylinder is installed at one end of the second sliding plate.

[0006] The crossbeam has multiple sets of screw holes, and the top of the connecting frame is equipped with a locking screw.

[0007] Guide rods slide through both ends of the soil turning frame, and one end of the guide rod is connected to the crossbeam. A second screw is threaded through the middle of the soil turning frame, and one end of the second screw is rotatably connected to the crossbeam.

[0008] The support frame is equipped with a liquid storage tank, a pump liquid extraction assembly is mounted on the support frame, a spray frame is mounted on one side of the outer wall of the support frame, and a water pipe connects the spray frame and the pump liquid extraction assembly.

[0009] The storage tank is equipped with a rotating stirring rod inside, and a stirring motor that is connected to the stirring rod is installed at one end of the outer wall of the storage tank.

[0010] Both the first screw and the second screw have anti-slip rotating blocks at one end.

[0011] Beneficial effects:

[0012] Through the coordinated action of the rotating plate, push rod, and spring, when the tiller encounters hard obstacles such as rocks, the compressed spring provides buffering and avoidance. After avoiding the obstacle, the spring automatically pushes the tiller back to the working position using its restoring elasticity. This reduces the repeated impact loads between the tiller and obstacles during continuous vehicle movement, which could lead to plastic deformation or even breakage of the shovel body. At the same time, the spring preload can be adjusted via the screw, allowing users to flexibly adjust the tilling force of the tiller according to soil conditions. This prevents the tiller from over-tilling soft soil, which could damage the soil structure, or from swinging arbitrarily in hard soil, which could affect the work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 As shown, a fertilization device for vegetable greenhouses includes a vehicle body 1, a support frame 2 installed at the rear end of the vehicle body 1, a soil turning frame 3 connected to one end of the support frame 2, a crossbeam 4 connected to the bottom side of the soil turning frame 3, multiple sets of connecting frames 5 installed on the crossbeam 4, a rotating plate 7 rotatably connected to one end of the connecting frame 5 via a rotating shaft 6, a soil turning plow 8 installed at one end of the rotating plate 7, a limiting frame 9 for limiting the rotation range of the rotating plate 7 installed on one side of the connecting frame 5, a bracket 10 connected to one side of the connecting frame 5, and an adjusting cylinder 11 installed at the other end of the bracket 10, a first sliding plate 12 and a second sliding plate 14 slidably connected to the two ends of the adjusting cylinder 11 respectively, a spring 16 provided between the first sliding plate 12 and the second sliding plate 14, a first screw 13 threaded through the interior of the adjusting cylinder 11 rotatably connected to one end of the first sliding plate 12, and a push rod 15 slidably through the interior of the adjusting cylinder 11 installed at one end of the second sliding plate 14; wherein the limiting frame 9 is used to limit the rotation range of the rotating plate 7, so that it can only rotate in the direction of the adjusting cylinder 11.

[0021] During operation, the driver moves the vehicle 1 forward, and the soil turning plow 8 turns the soil. When the soil turning plow 8 encounters large rocks or other hard obstacles, it moves towards the adjusting cylinder 11 via the rotating shaft 6 to avoid the obstacle. During this process, the rotating plate 7 pushes the push rod 15, which is in elastic contact with it, causing the second sliding plate 14 to retract into the adjusting cylinder 11. The spring 16 is compressed and absorbs a certain amount of impact force. After the obstacle avoidance is completed, the spring 16 pushes the second sliding plate 14 and the push rod 15 out of the adjusting cylinder 11 under the restoring elasticity. This push rod 15 pushes the rotating plate 7 and the soil turning plow 8 back to the working position. At the same time, the position of the first sliding plate 12 is adjusted by rotating the first screw 13 according to the soil resistance of different soil types, thereby adjusting the preload of the spring 16 and changing the soil turning force. For example, this avoids excessive soil turning in soft soil, which may damage the soil structure, or the soil turning plow 8 swinging arbitrarily in hard soil, which may affect the soil turning effect.

[0022] Furthermore, multiple sets of screw holes 17 are provided on the crossbeam 4, and a locking screw 18 is provided at the top of the inside of the connecting frame 5. During operation, by removing the locking screw 18 from the corresponding screw hole 17, the connecting frame 5 can be slidably adjusted on the crossbeam 4. This allows for flexible adjustment of the position of multiple sets of tillage plows 8 according to the vegetable planting spacing requirements. After adjustment, the locking screw 18 is screwed back into the corresponding screw hole 17 to firmly fix the connecting frame 5 in the new position, thereby improving the applicability of this device.

[0023] Furthermore, guide rods 19 slide through both ends of the soil-turning frame 3, and one end of the guide rod 19 is connected to the crossbeam 4. A second screw 20 is threaded through the middle of the soil-turning frame 3, and one end of the second screw 20 is rotatably connected to the crossbeam 4. During operation, by rotating the second screw 20, the crossbeam 4 moves up and down under the guidance of the guide rods 19, thereby driving the adjustment of the height position of multiple sets of soil-turning plows 8. This facilitates adjustment according to the type of vegetable, such as shallow-rooted or deep-rooted crops, further improving the applicability of the device.

[0024] Furthermore, a liquid storage tank 21 is installed inside the support frame 2, and a pump-driven liquid extraction assembly 22 is installed on the support frame 2. A spray frame 24 is installed on one side of the outer wall of the support frame 2, and a water pipe 23 connects the spray frame 24 and the pump-driven liquid extraction assembly 22. A stirring rod 25 is rotatably installed inside the liquid storage tank 21, and a stirring motor 26 connected to the stirring rod 25 is installed at one end of the outer wall of the liquid storage tank 21. During operation, the pump-driven liquid extraction assembly 22 extracts the solution from the liquid storage tank 21 and transports it to the spray frame 24 through the water pipe 23. The solution is sprayed onto the soil or crops through multiple sets of nozzles set on the spray frame 24. During this process, the continuous stirring by the stirring rod 25 and the stirring motor 26 prevents the solution from separating or settling, ensuring that the sprayed solution is uniform and effective.

[0025] Furthermore, both the first screw 13 and the second screw 20 are provided with anti-slip rotating blocks at one end; the anti-slip rotating blocks provide a gripping part that is easy to operate, making it convenient for personnel to operate.
