Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a variable fertilizer applicator based on soil moisture. Background Technology

[0002] Fertilization is one of the core links in agricultural production to ensure crop yield and quality. Traditional fertilization methods mainly adopt "uniform fertilization", that is, applying the same type and dosage of fertilizer throughout the field. This method ignores the spatial heterogeneity of soil characteristics and crop growth conditions in the field, which can easily lead to excessive application of fertilizer in areas with low demand, resulting in resource waste and environmental pollution (such as eutrophication of water bodies and soil acidification); while insufficient fertilization in areas with high demand limits the realization of crop yield potential. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a simple, rationally designed, and easy-to-use variable fertilizer applicator based on soil moisture. It controls the amount of fertilizer applied by controlling the rotation speed, thereby discharging the fertilizer according to the soil's needs. It also adjusts the water flow rate according to the soil's moisture level to promote fertilizer dissolution.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a base frame, a material cylinder, and support blocks. A material cylinder is disposed on the upper side of the base frame, and support blocks are disposed on both the front and rear sides of the outer ring wall of the material cylinder, facing each other. The bottom of the support blocks is fixed to the base frame. A slot is formed inside the base frame, and the slot is located between the four support blocks; it also includes: The material feeding disc is set in a slot, and the discharge hopper at the bottom of the material cylinder is inserted into the material feeding disc. A solenoid valve is installed on the discharge hopper. A central roller is set inside the material feeding disc, and several distribution hoppers are evenly distributed on the outer ring wall of the central roller. A discharge hopper is set at the bottom of the material feeding disc. The central shaft is fixedly installed on the front side of the central roller, and the front end of the central shaft is screwed through the front side wall of the feeding disc via a bearing and then installed on the front side of the feeding disc. A variable component, wherein the variable component is disposed on the front side of the central axis; The water tank is fixedly installed on the base frame and is located on the right side of the slot. A water pump is installed on one side of the water tank. The water inlet of the water pump is connected to the water tank through a water pipe. A drain pipe is installed at the water outlet of the water pump. The drain pipe passes through the slot and is equipped with a water valve. The drain pipe is correspondingly installed with the discharge hopper. With the above technical solution design, when the base frame moves, the fertilizer inside the material cylinder falls into the material feeding plate and is placed in the material distribution hopper; the material distribution hopper is driven to rotate by the variable component, so that the fertilizer falls from the discharge hopper onto the soil. The water tank irrigates the soil on which the fertilizer has been applied to promote fertilizer dissolution, and the flow rate of the drainage pipe is controlled by the water valve according to the soil moisture.

[0005] As a further improvement of this utility model, the variable component includes: A cam is fixed to the front end of a central shaft, and a connector is hinged to the front side of the cam via a hinge shaft. A movable block, which is hinged to the right front side of the connector via a hinge shaft; The drive motor is fixedly mounted on the right side wall of the slot by a motor bracket, and the output end of the drive motor is provided with a lead screw, which is threaded through the movable block, and the front side of the movable block is slidably mounted on the front side wall of the slot by a sliding pair. The above technical solution design starts the drive motor to rotate the lead screw, which drives the moving block by thread. The moving block moves by hinged connection of the connecting parts, which drives the cam to rotate around the center of the central axis and the feed plate, thereby driving the central roller to rotate and making the feed hopper rotate.

[0006] As a further improvement of this utility model, a card holder is fixedly provided on the rear side of the feeding disc, and the card holder is configured with an inverted "L" shape and is clamped on the base frame; a positioning platform is provided on the base frame, and the positioning platform is located on the rear side of the slot and is inserted into the horizontal end of the card holder. The above technical solution is used to support the feeding disc.

[0007] As a further improvement of this utility model, a limiting frame is provided on the horizontal end of the card holder, which is movably mounted on the sliding rail, and the limiting frame is set in an inverted "L" shape; the bottom of the vertical end of the limiting frame is in contact with the base frame; a threaded tube is provided on the outer wall of the vertical end of the limiting frame, and a threaded rod is threaded through the threaded tube; a moving motor is provided on one side of the threaded rod, and the moving motor is fixed on the base frame by a motor bracket; and the threaded rod is connected to the output end of the moving motor by a coupling. By designing the above technical solution, the moving motor is started to rotate the threaded rod, which drives the threaded tube and causes the limit frame to move on the base frame to clamp onto the horizontal end of the clamp, thus strengthening the stability of the clamp.

[0008] As a further improvement of this utility model, a traction frame is provided on the left side of the base frame and a handrail is provided on the right side of the base frame. Through the above technical solution design, the traction frame is connected to external agricultural machinery to pull the base frame.

[0009] The working principle of this utility model is as follows: A traction frame connects the base frame to external agricultural machinery, pulling the base frame to move it. Fertilizer is poured into the feed cylinder. When the base frame moves, the fertilizer inside the feed cylinder falls into the feeding disc and is placed in the distributing hopper. The drive motor is started to rotate the lead screw, which drives the moving block through a threaded connection. The movement of the moving block is driven by the hinge of the connecting parts, which drives the cam to rotate around the center axis and the screw connection center of the feeding disc, thereby driving the central roller to rotate and making the distributing hopper rotate. This allows the fertilizer to fall from the discharge hopper onto the soil. The speed of the drive motor is controllable to control the rotation of the lead screw. The higher the speed, the faster the distributing hopper rotates, and the less fertilizer is in it. Conversely, the slower the rotation, the slower the distributing hopper rotates, and the more fertilizer is in it. A water tank irrigates the soil on which fertilizer has been applied to promote fertilizer dissolution. The flow rate of the drain pipe is controlled by a water valve according to the soil moisture.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Add a feeding disc to the lower side of the material cylinder, and add a distributing hopper inside the feeding disc. By rotating the distributing hopper, the fertilizer in the material cylinder can be supported and separated, so as to achieve controllable fertilizer distribution. 2. The lead screw rotates to drive the moving block, and the hinged connection of the connecting parts drives the cam to rotate the central shaft. The speed of the drive motor is controllable to control the speed of the central shaft. 3. Add a clamp to the rear side of the feeding plate and reinforce the stability of the feeding plate by limiting and clamping the clamp. Attached Figure Description

Fertilizer is poured into the feed cylinder 2. When the base frame 1 moves, the fertilizer inside the feed cylinder 2 falls into the feed pan 4 and is placed in the distribution hopper 7. The drive motor 10-4 is started to rotate the lead screw 10-5, which drives the moving block 10-3 by thread.
