Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a soil stratification and improvement device for reclamation of farmland, including a trolley 1 and a pusher 2. The pusher 2 is set on the top of the trolley 1, which makes it convenient for the operator to push the device to move. It is similar to the structure of a common hand-pushed wheelbarrow. The bottom is equipped with wheels, which makes it easy to push in the farmland.

[0026] Four elastic support members 3 are respectively installed on the top of the trolley 1;

[0027] The medicine box 4 is set between four elastic support members 3 and is used to store the pesticide solutions needed for soil improvement. The material is generally made of corrosion-resistant plastic or metal to ensure that the pesticides are stored safely and are not easily damaged.

[0028] Mounting bracket 5 is located at the bottom of medicine box 4;

[0029] Several liquid dispensing mechanisms 6 are installed through the mounting frame 5 and connected to the bottom of the medicine tank 4;

[0030] Drive component 7 is located on top of medicine box 4 and connected to pusher 2;

[0031] The induction switch 8 is set on the top of the trolley 1; the outer wall of the medicine box 4 is provided with a pressure plate 9 that is positioned opposite to the induction switch 8; the induction switch 8 is used to sense the pressing signal of the pressure plate 9. When the pressure plate 9 follows the medicine box 4 down and presses the induction switch 8, the induction switch 8 sends a signal and cooperates with the external controller to control the liquid dispensing mechanism 6 to dispense liquid once.

[0032] The drive component 7 is used to drive the medicine tank 4 to descend so that the liquid dispensing mechanism 6 can be inserted into the soil, and the elastic support component 3 is used to push the liquid dispensing mechanism 6 to reset.

[0033] Specifically, refer to Figure 3The elastic support 3 includes a slide bar 31 mounted on the top of the trolley 1; a stop block 32 mounted on the top of the slide bar 31; a lifting block 33 slidably sleeved on the outer wall of the slide bar 31, which can move up and down along the slide bar 31, and its movement drives the lifting and lowering of components such as the medicine box 4. The slide bar 31 plays a guiding and supporting role, providing a track for the up and down sliding of the lifting block 33; the stop block 32 is used to prevent the lifting block 33 from slipping off the slide bar 31, and plays a limiting protection role; a spring 34 sleeved on the outer wall of the slide bar 31 and connected at both ends to the bottom of the lifting block 33 and the top of the trolley 1 respectively. When the medicine box 4 descends, the spring 34 is compressed and stores elastic potential energy; when the external force is removed, the spring 34 releases the elastic potential energy and pushes the lifting block 33 and the medicine box 4 to return to their original positions.

[0034] Specifically, refer to Figure 3 The dispensing mechanism 6 includes a water pump 61 that runs through the mounting frame 5 and whose input end is connected to the bottom of the medicine tank 4; a pipe rack 62 that is installed on the output end of the water pump 61. The function of the water pump 61 is to draw out the medicine in the medicine tank 4 and deliver it to the pipe rack 62. The amount of medicine delivered can be adjusted by controlling the power and working time of the water pump 61; and several dispensing pipes 63 that are detachably installed at the bottom of the pipe rack 62 by threads. The pipe rack 62 is used to distribute and guide the medicine to each dispensing pipe 63. Its structural design must ensure that the medicine can be evenly distributed to each dispensing pipe 63.

[0035] Specifically, refer to Figure 4 The discharge pipe 63 is composed of several pipe sleeves joined together by threads, with a pointed bottom. The outer wall of the pipe sleeve has a discharge hole 631. This joining method allows the length of the discharge pipe 63 to be adjusted according to the required improvement depth. The pointed bottom facilitates insertion into the soil, and the discharge hole 631 is used to evenly spray the agent into the soil.

[0036] Specifically, refer to Figure 2-3 The driving component 7 includes four mounting plates 71 respectively disposed on the top of the medicine box 4; a limiting rod 72 disposed between two opposite mounting plates 71; a transverse block 73 slidably sleeved on the top of the limiting rod 72, the limiting rod 72 limiting and guiding the movement of the transverse block 73, ensuring that the transverse block 73 can only move along the direction of the limiting rod 72; a driving frame 74 hinged inside the push frame 2, which drives the driving frame 74 to rotate around the hinge point when the transverse block 73 moves, thereby causing the medicine box 4 to rise or fall; a hinge seat 75 disposed on the top of the transverse block 73 and hinged to the bottom of the driving frame 74, which serves to connect and transmit power, ensuring that the movement of the transverse block 73 can be effectively converted into the rotation of the driving frame 74; the transverse block 73 can move laterally on the limiting rod 72, and its movement drives the driving frame 74 to move through the hinge seat 75.

[0037] Working principle

[0038] The operator pushes the cart 1 through the pusher 2 to move the device to the location of the reclaimed farmland that needs soil improvement. During the movement, the wheels at the bottom of the cart 1 provide convenient movement.

[0039] After reaching the target position, the pushing device is stopped to stabilize the position. The operator drives the medicine tank 4 to descend through the drive component 7. In specific operation, the operator pushes the transverse block 73 to move on the limit rod 72. The transverse block 73 drives the drive frame 74 to rotate around its hinge point in the push frame 2 through the hinge seat 75. As the drive frame 74 rotates, the medicine tank 4 gradually descends. During the descent of the medicine tank 4, the spring 34 of the elastic support component 3 is compressed, and the lifting block 33 slides down along the slide rod 31. The liquid outlet pipe 63 gradually inserts into the soil as the medicine tank 4 descends. Since the bottom of the liquid outlet pipe 63 is sharp, it can be inserted into the soil relatively smoothly. The operator can pre-assemble the liquid outlet pipe 63 of appropriate length according to the actual soil depth required to ensure that the agent can be delivered to the target soil layer.

[0040] When the medicine tank 4 descends to a certain level, the pressure plate 9 on the outer wall of the medicine tank 4 descends with the medicine tank 4 and presses down on the induction switch 8 on the top of the trolley 1. After the induction switch 8 is pressed down, it sends a signal to control the liquid dispensing mechanism 6 to dispense liquid once. Specifically, the signal sent by the induction switch 8 is sent to the external controller, which triggers the water pump 61 to work. The water pump 61 draws the medicine in the medicine tank 4 and distributes it to each liquid dispensing pipe 63 through the pipe rack 62. The medicine is sprayed out from the liquid dispensing hole 631 on the outer wall of the liquid dispensing pipe 63 and evenly sprayed into the soil of the soil layer to improve the soil layer.

[0041] Once the liquid is dispensed, the operator simply needs to release the drive unit 7. The medicine tank 4 rises and resets under the restoring force of the spring 34 of the elastic support unit 3. The spring 34 releases its elastic potential energy, pushing the lifting block 33 to slide upward along the slide rod 31, thereby causing the medicine tank 4 to rise and the liquid outlet pipe 63 to be pulled out of the soil. At this point, the device completes one soil stratification improvement operation cycle. If different soil layers need to be improved, the above operation process can be repeated, and the length of the liquid outlet pipe 63 can be adjusted as needed.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
