Description

Technical Field

[0001] The present invention relates to the technical field of fertilization, and in particular to a fertilization device and method for agricultural corn planting. Background Art

[0002] Fertilizers need to be applied to corn at different stages of planting to ensure its stable growth. At the same time, liquid fertilizer application is a new fertilizer application technology that has been studied and promoted in recent years. Compared with traditional solid fertilizer application, it has many advantages such as cheap processing, full utilization of fertilizer effect, high utilization efficiency, reduced fertilizer loss, reduced fertilizer application cost, and reduced environmental pollution.

[0003] The application of fertilizer is crucial in corn planting, which can enhance the stress resistance of corn and promote the development of the root system. At the same time, due to environmental interference such as soil, the growth of corn in some local areas is slow. Therefore, it is necessary to explore the slow-growing corn in local areas and carry out targeted topdressing. At the same time, in order to improve the effect of fertilizer application, it is necessary to accurately control the depth and position of fertilizer application, and the amount of fertilizer applied is also crucial. Therefore, a fertilizer application device is needed to complete the fertilization action during the application process.

[0004] A hole digging and fertilizer application machine disclosed in a patent application with reference publication number CN103039167B drives the ground wheel to rotate through a power connection, and the forward power drives the hole digging device to operate, digging holes of equal depth and consistent distance, and drives the fertilizer spreader to operate, so that the fertilizer in the upper fertilizer box falls into the fertilizer application box through the fertilizer spreader, and the fertilizer is applied in the hole, completing the sequential action of digging the hole first and then applying the fertilizer.

[0005] At present, for the fertilization method in corn planting, a hole digging device is mostly used in combination with a fertilizer dispenser to transport fertilizer to the expected depth of the corn planting stage. For example, the above-mentioned fertilizer dispenser uses a plurality of hole digging plates arranged in a circular array to complete continuous hole digging and fertilizer application. However, the hole digging plates designed in the above-mentioned fertilizer dispenser are very likely to cause excessive disturbance to the local soil during the hole digging process, resulting in a large amount of subsequent fertilizer loss, affecting the fertilization accuracy;

[0006] At the same time, the above-mentioned fertilizer spotting machine cannot continuously clean the digging plate during fertilization, so when adapting to different soil environments, a large amount of residue is likely to occur, affecting the effect of digging hole fertilization, and the above-mentioned fertilizer spotting machine cannot freely control the digging hole depth and the amount of fertilizer applied according to the needs of fertilization, and cannot quickly find the corn plants that need topdressing, and cannot adapt to the continuous corn topdressing work. At the same time, it cannot intuitively mark the fertilization area, which is not conducive to subsequent re-inspection, increases the difficulty of subsequent fertilization, and is prone to excessive fertilizer application and local deficiency, affecting the normal growth of corn.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The present invention is provided with a fertilization chamber, and intermittent control is performed on the pusher through the reciprocating member. When the piercing member moves to the predetermined fertilization depth path, the pusher actively delivers the liquid fertilizer in the feeding space into the feeding channel. When the piercing member moves to the fertilization depth, the reciprocating member moves upward, and continuously pushes the gas in the pressurization space into the feeding channel to complete the pressurization, and controls the feeding mechanism to open, and pressurizes the liquid fertilizer and discharges it from the feeding channel through the dynamic plug.

In the fertilization path of the piercing part, the piercing part is controlled by the rotating part to enter and exit the soil in a rotating posture, thereby reducing the friction between the piercing part and the soil, so that the piercing part can be smoothly adapted to be used in different soil environments, which is conducive to the entry and exit of the piercing part and reduces the disturbance of the soil. At the same time, in the reset path of the piercing part, it can also exit the soil in a rotating posture. Through the rotating design, the residual amount of soil on the piercing part is greatly reduced, and the difficulty of subsequent cleaning is effectively reduced;

[0057] 3. The present invention is provided with a marking unit. When the piercing member moves, the marking unit releases contact with the soil. The top limit of the piercing member can be completed through the marking unit, thereby reducing the amount of soil damage. In addition, the design of the marking unit can perform multi-mode marking treatment on corn for topdressing, which is beneficial for agricultural personnel to re-inspect according to subsequent growth conditions and ensure the consistency of corn growth. At the same time, the marking unit can be used to complete the active cleaning of the piercing member to avoid the problem of a large amount of residual soil on the piercing member affecting subsequent fertilization.

[0058] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the intercommunication pipe 14 is interconnected with the air outlet pipe 604 and the discharge pipe 606 to complete the joint transportation;

[0091] A dynamic plug 15 is slidably disposed at the bottom of the feed channel 5 to complete the plugging. A rack 16 is disposed on one side of the top of the dynamic plug 15, and a sliding area 1 that cooperates with the rack 16 is opened on one side of the inner wall of the feed channel 5;

[0092] The piston plate 17 is provided with a sliding seal in the feed channel 5. A second rack 18 is installed on one side of the bottom of the piston plate 17. A second sliding area cooperating with the second rack 18 is provided on one side of the inner wall of the feed channel 5. An exhaust hole for exhausting the piston plate 17 is provided on the top of the feed channel 5.

[0093] The switching gear 19 is rotatably disposed in the feeding channel 5, and the switching gear 19 is meshed with the first rack 16 and the second rack 18 to complete the control of the dynamic plug 15;

[0099] It is worth mentioning that: when the piercing member 4 is controlled to enter the pressurized fertilization: by providing a feeding mechanism, the position of the corn that needs topdressing is obtained through the collection unit 10, the reciprocating member 11 is started, and the push-in member 7 is pushed downward in the fertilization chamber 6, thereby squeezing out the liquid fertilizer in the feeding space 9, and sending the liquid fertilizer into the feeding channel 5 through the discharge pipe 606 and the interconnecting pipe 14 for temporary storage.

Secondly, the piston plate 17 and the second rack 18 are pulled upward by the push arm 20. Under the conversion of the switching rack, the first rack 16 and the dynamic plug 15 are moved out of the feeding channel 5, thereby releasing the feeding channel 5. Then, the liquid fertilizer is discharged into the soil through the release area 152 and the discharge port 154. Through the design of the annular filter 155, the soil can be isolated to avoid blockage problems. Subsequently, the pusher 7 moves downward through the first rack 16 and the second rack 18 to control the dynamic reset to complete the blocking operation. In this way, when the piercing member 4 is controlled to move upward by the reciprocating member 11, the fertilization chamber 6 is controlled to actively complete the loading and feeding operations, thereby optimizing the fertilization process, reducing the control difficulty, and facilitating the smooth progress of topdressing work.

[0100] Among them, the electrical components such as the collection unit 10 and the reciprocating member 11 are all connected to switches through wires, and the switches are electrically connected to a controller, and the specific structure of the controller is not limited.
