Description

Technical Field

[0001] The invention belongs to the technical field of corn fertilization, and in particular relates to excavation equipment for corn fertilization. Background Art

[0002] Common fertilizers for corn include urea, ammonium bicarbonate, ammonium chloride, etc. In the last topdressing, it is recommended to mix urea and potassium fertilizer in a ratio of 4:1, which is better than using nitrogen fertilizer alone. By reasonably selecting the time and method of fertilization, and adjusting it in combination with soil conditions and corn growth requirements, corn growth and yield can be effectively promoted.

[0003] After digging a hole with a hoe or shovel, fertilizer needs to be poured into the hole, and then the fertilizer needs to be simply buried to reduce loss, which causes the problem of troublesome pit digging and fertilizing operations.

[0004] For this reason, we propose a corn fertilization excavation equipment to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the operation of digging pits for fertilizing is troublesome, and a digging device for fertilizing corn is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A digging device for fertilizing corn comprises a trolley, the lower end of which is symmetrically and fixedly connected to a guide rail, a shovel head is slidably mounted on the guide rail, a tension spring is provided between the guide rail and the shovel head, the tension spring is movably sleeved on the guide rail, one end of the tension spring is fixedly connected to the guide rail, the other end of the tension spring is fixedly connected to the shovel head, a material guide hopper is fixedly connected inside the shovel head, the upper end of the material guide hopper is movably in contact with the trolley, and the lower space of the trolley is docked and matched with the inner space of the material guide hopper. Put solid fertilizer in the cart and push the cart to move. When passing by one side of the corn root, lift the rear end of the cart upwards and shovel the shovel head into the soil. With the help of the reaction force of the soil on the shovel head, the shovel head overcomes the elastic force of the tension spring and slides backward, so that the guide bucket and the inner space of the cart are docked, and the fertilizer in the cart falls into the guide bucket, enters the shovel head through the guide bucket, and falls into the pit dug by the shovel head. Press the rear end of the cart downwards to make the head of the cart drive the guide rail, and the shovel head is lifted up through the guide rail, so that the shovel head leaves the soil, which is convenient for excavation and fertilization.

[0008] Preferably, the trolley includes a body, a handle is fixedly connected to the rear of the body, and a discharge port is hollowed out at the lower end of the body, and the discharge port matches the inner space of the guide hopper. When the shovel head is inserted into the soil, the soil is used to prevent the shovel head from moving forward, and the handle is continuously pushed to drive the body forward, so that the shovel head slides backward relative to the body, so that the discharge port is aligned with the inner space of the guide hopper, so that the fertilizer in the body enters the guide hopper, which is convenient for automatic fertilization during excavation.

[0009] Preferably, a retaining ring is fixedly connected to the handle. After holding the hand on the handle, the retaining ring is used to block the hand in front of the hand to prevent the hand from excessively sliding forward after the shovel head is inserted into the soil, thereby improving the stability of the hand-holding operation.

[0010] Preferably, the handle is covered with a buffer sponge ring, which is fixedly connected to the retaining ring. After holding the hand on the handle, the buffer sponge ring is blocked between the hand and the retaining ring, and the buffer sponge ring is used to buffer the impact force of the hand, and the buffer sponge ring is used to increase the contact surface of the hand, reduce the pressure, and improve the comfort of operation.

[0011] Preferably, the guide rail includes a first fixed block and a second fixed block, a guide rod is fixedly connected between the first fixed block and the second fixed block, and the upper ends of the first fixed block and the second fixed block are fixedly connected to the lower end of the vehicle body. The guide rod is used to conveniently guide the shovel head to slide.

[0012] Preferably, the shovel head includes a sliding sleeve, the sliding sleeve is slidably sleeved on the guide rod, the lower end of the sliding sleeve is fixedly connected to a first connecting plate, the lower part of the first connecting plate is fixedly connected to a second connecting plate, the front part of the second connecting plate is fixedly connected to a conical shovel head, the tension spring is movably sleeved on the guide rod, one end of the tension spring is fixedly connected to the first fixed block, and the other end of the tension spring is fixedly connected to the sliding sleeve. The elastic force of the tension spring is used to act on the sliding sleeve, and when the conical shovel head leaves the soil, the elastic force of the tension spring is used to drive the sliding sleeve to recover forward, so that the shovel head drives the guide hopper to stagger with the trolley, thereby facilitating automatic blocking of fertilization.

[0013] Preferably, a reinforcing plate is fixedly connected to the rear of the first connecting plate, so as to increase the firmness between the first connecting plates.

[0014] Preferably, the guide hopper includes a hopper body, the upper end of the hopper body is in active contact with the bottom of the vehicle body, the outside of the hopper body is fixedly connected with a valve plate, the valve plate is in active contact with the bottom of the vehicle body, the valve plate blocks the lower side of the discharge port, the lower end of the hopper body is fixedly connected with a guide pipe, the lower end of the guide pipe is fixedly connected with a fixed frame, and the fixed frame is fixedly connected to the inside of the first connecting plate. When the hopper body and the valve plate slide backward, the hopper body is aligned with the discharge port, so that the fertilizer in the vehicle body falls into the hopper body through the discharge port, enters the guide pipe through the hopper body, and is discharged into the soil pit shoveled out by the conical shovel head through the guide pipe, which is convenient for automatic feeding.

[0015] Preferably, the root of the guide pipe is fixedly connected with an air inlet, and the internal spaces of the guide pipe and the air inlet are connected. The air inlet is used to connect the guide pipe with the external space, so that gas can smoothly enter the guide pipe, thereby improving the fluency of fertilization.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. Put the solid fertilizer in the trolley and push the trolley to move. When passing by the side of the corn root, lift the rear end of the trolley upwards and shovel the shovel head into the soil. With the help of the reaction force of the soil on the shovel head, the shovel head overcomes the elastic force of the tension spring and slides backward, so that the guide hopper and the inner space of the trolley are docked, and the fertilizer in the trolley falls into the guide hopper, enters the shovel head through the guide hopper, and falls into the pit dug by the shovel head. Press the rear end of the trolley downwards to make the head of the trolley drive the guide rail, and the shovel head is lifted up through the guide rail, so that the shovel head leaves the soil, which is convenient for excavation and fertilization.

[0018] 2. After the shovel head is inserted into the soil, use the soil to prevent the shovel head from moving forward, continue to push the handle to drive the vehicle body forward, and make the shovel head slide backward relative to the vehicle body, so that the discharge port is aligned with the internal space of the guide hopper, so that the fertilizer in the vehicle body enters the guide hopper, which is convenient for automatic fertilization during excavation.

[0019] 3. Use the elastic force of the tension spring to act on the sliding sleeve. When the conical shovel head leaves the soil, use the elastic force of the tension spring to drive the sliding sleeve to recover forward, so that the shovel head can drive the guide hopper and the trolley to stagger, thereby facilitating automatic blocking of fertilization.

[0020] 4. When the bucket body and valve plate slide backward, the bucket body is aligned with the discharge port, so that the fertilizer in the vehicle body falls into the bucket body through the discharge port, enters the guide pipe through the bucket body, and is discharged into the soil pit shoveled out by the conical shovel head through the guide pipe, which is convenient for automatic loading.
