Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a quantitative fertilization mechanism for corn sowing. Background Technology

[0002] Sowing and fertilizing are important steps in corn cultivation. Scientific and rational fertilization can effectively improve corn yield and quality. Corn requires a large number of nutrients, especially macronutrients such as nitrogen, phosphorus, and potassium. Rational and quantitative fertilization can meet the nutritional needs of corn at different growth stages, promote robust plant growth, and increase yield.

[0003] Announcement No. CN221203276U relates to a quantitative fertilization mechanism, including a fertilizer box. The fertilizer box has an adjustable fertilization mechanism inside and at its bottom. The adjustable fertilization mechanism includes a partition fixedly installed inside the fertilizer box, a handle fixedly installed on one side of the fertilizer box, and two fixed plates fixedly installed at the bottom of the fertilizer box. A rotating shaft is rotatably connected between the two fixed plates, and a movable wheel is fixedly installed on the outer side of the rotating shaft. This quantitative fertilization mechanism, through the adjustable fertilization mechanism, uses the fertilizer box to deliver fertilizer to the inside of a flow pipe and a discharge pipe for output. The output shaft of the vibrating motor vibrates, driving the movable rod and the discharge pipe to vibrate rapidly, facilitating discharge. A reciprocating screw can drive the movable plate to move up and down, facilitating the sealing or unsealing of the flow pipe to reduce discharge volume, or opening the seal to expand the flow space and increase the fertilizer application rate, thus improving the flexibility and practicality of the device.

[0004] However, the above-mentioned device has some problems in actual use: First, the device relies on manual rotation of the reciprocating screw, which is not only prone to errors, but also increases the workload of operators when precise fertilization is required. Due to human factors, it is easy to make mistakes or misoperations, resulting in the amount of fertilizer discharged not matching the actual needs. In addition, the device does not have effective sealing measures during the fertilizer discharge process. When the moving plate moves, fertilizer may leak or remain through gaps, affecting the fertilization effect. Although the vibrating motor can assist in fertilizer discharge, it cannot ensure the uniform distribution of fertilizer in the flow pipe and discharge pipe. Especially when the amount of fertilizer is large, fertilizer is prone to accumulate at the discharge port, which in turn affects the uniformity and accuracy of fertilization. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a quantitative fertilization mechanism for corn planting.

[0006] This utility model is achieved by the following technical solution: a quantitative fertilizer application mechanism for corn sowing, including a storage box, on both sides of the lower surface of the storage box, directional grooves are provided, a sliding block is slidably connected inside the directional groove, a blocking cross plate is slidably connected inside the sliding block, an auxiliary sealing gasket is provided on the upper surface of the blocking cross plate, and an electric push rod is fixedly connected to the outer surface of the blocking cross plate.

[0007] Through the above technical solution, the fertilizer discharge flow can be precisely controlled by adjusting the position of the shielding plate, thereby achieving quantitative fertilization. The design of the auxiliary sealing gasket effectively prevents fertilizer leakage and residue, avoiding fertilizer waste. The use of electric push rod makes the movement of the shielding plate more convenient, reducing the difficulty and intensity of manual operation.

[0008] As a further improvement to the above solution, a liquid level observation window is provided at the front end of the storage tank, and a filling groove is provided on the upper surface of the storage tank, with a sealing plug snapped into the inside of the filling groove.

[0009] Through the above technical solutions, the design of the liquid level observation window allows operators to know the amount of fertilizer inside the storage tank at any time, avoiding fertilization interruption due to insufficient fertilizer. The design of the filling tank and sealing plug makes the fertilizer filling process more convenient, while ensuring the sealing of the storage tank and preventing fertilizer leakage.

[0010] As a further improvement to the above solution, a load-bearing base is fixedly connected to the outer surface of the storage box, and fertilizer discharge holes are opened in the middle of the lower surface of both the storage box and the load-bearing base.

[0011] As a further improvement to the above solution, the shielding plate is located below the fertilizer discharge hole opened on the lower surface of the storage box, and the shielding plate is slidably connected to the lower surface of the storage box by a sliding block.

[0012] By adjusting the position of the shielding plate, the exposed area of ​​the fertilizer discharge hole can be precisely controlled, thereby achieving precise control of the fertilizer flow rate. The moving distance of the shielding plate can be adjusted according to actual needs, making it suitable for different fertilizer application requirements.

[0013] As a further improvement to the above solution, casters are fixedly connected to the four corners of the lower surface of the load-bearing base.

[0014] With the above technical solution, the moving wheels are installed at the four corners of the load-bearing base, which allows the fertilizing mechanism to move easily on the ground. By pushing or pulling the fertilizing mechanism, the moving wheels roll on the ground, reducing friction and improving the mobility of the fertilizing mechanism.

[0015] As a further improvement to the above solution, a servo motor is fixedly connected to the middle of the upper surface of the storage box, and a screw conveyor shaft is fixedly connected to the output end of the servo motor.

[0016] Through the above technical solutions, the design of the screw conveyor shaft can effectively prevent fertilizer from accumulating at the discharge hole and avoid blockage. The combined use of the servo motor and the screw conveyor shaft makes the fertilizer delivery more uniform and stable, improving the efficiency and quality of fertilization.

[0017] As a further improvement to the above solution, the screw conveyor shaft is located inside the storage bin, and a control panel is fixedly connected to the outer surface of the storage bin.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes an electric push rod to achieve automatic adjustment of the shielding plate, eliminating the need for manual operation and greatly improving convenience and efficiency. The design of the auxiliary sealing gasket enhances the sealing performance of the shielding plate, effectively preventing fertilizer residue or leakage during discharge. The spiral conveyor shaft gradually pushes the fertilizer towards the fertilizer discharge hole. By controlling the rotation speed of the servo motor, the amount of fertilizer conveyed can be precisely controlled, preventing excessive fertilizer accumulation at the outlet and ensuring uniform fertilizer distribution and fertilization effect.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of a quantitative fertilization mechanism for corn planting includes a storage box 1. Orientation grooves 2 are provided on both sides of the lower surface of the storage box 1. A sliding block 3 is slidably connected inside the orientation groove 2. A blocking plate 4 is slidably connected inside the sliding block 3. An auxiliary sealing gasket 13 is provided on the upper surface of the blocking plate 4. An electric push rod 5 is fixedly connected to the outer surface of the blocking plate 4. By controlling the extension and retraction of the electric push rod 5, the blocking plate 4 is driven to slide inside the sliding block 3. The change in the position of the blocking plate 4 can adjust the flow rate of fertilizer discharged from the storage box 1. The auxiliary sealing gasket 13 enhances the sealing performance of the blocking plate 4, preventing fertilizer from remaining or leaking through gaps during discharge.

[0030] The storage tank 1 has a liquid level observation window 6 at the front end and a filling groove on the upper surface of the storage tank 1. A sealing plug 7 is snapped into the inside of the filling groove. The liquid level observation window 6 allows the operator to observe the liquid level inside the storage tank 1 at any time so as to add fertilizer in time. The filling groove is used to add fertilizer into the storage tank 1. The sealing plug 7 snapped into the filling groove maintains the airtightness of the storage tank 1 and prevents fertilizer leakage.

[0031] A load-bearing base 8 is fixedly connected to the outer surface of the storage box 1, and fertilizer discharge holes 9 are opened in the middle of the lower surface of both the storage box 1 and the load-bearing base 8.

[0032] The blocking plate 4 is located below the fertilizer discharge hole 9 on the lower surface of the storage box 1. The blocking plate 4 is slidably connected to the lower surface of the storage box 1 via the sliding block 3. The blocking plate 4 slides on the lower surface of the storage box 1 via the sliding block 3, thereby changing the exposed area of ​​the fertilizer discharge hole 9. When the blocking plate 4 is completely below the fertilizer discharge hole 9, the fertilizer discharge hole 9 is completely blocked and the fertilizer cannot be discharged. When discharge is required, the exposed area of ​​the fertilizer discharge hole 9 is adjusted by controlling the moving distance of the blocking plate 4, thereby controlling the discharge flow rate of the fertilizer and realizing quantitative fertilization.

[0033] The four corners of the lower surface of the load-bearing base 8 are all fixedly connected with moving wheels 10. The design of the moving wheels 10 allows the fertilizer applicator to move smoothly on various terrains, improving the adaptability of the fertilizer applicator.

[0034] A servo motor 11 is fixedly connected to the middle of the upper surface of the storage box 1. A screw conveyor shaft 12 is fixedly connected to the output end of the servo motor 11. The servo motor 11 drives the screw conveyor shaft 12 to rotate. The screw conveyor shaft 12 pushes the fertilizer in the storage box 1 towards the fertilizer discharge hole 9 step by step. By controlling the speed of the servo motor 11, the amount of fertilizer conveyed can be precisely controlled to avoid excessive fertilizer accumulation at the outlet.

[0035] The screw conveyor shaft 12 is located inside the storage box 1, and the control panel 14 is fixedly connected to the outer surface of the storage box 1.

[0036] The implementation principle of a quantitative fertilization mechanism for corn planting in this embodiment is as follows: Personnel open the sealing plug 7 and add fertilizer into the storage tank 1 through the filling trough. The liquid level in the storage tank 1 is monitored through the liquid level observation window 6 to ensure an appropriate amount is added. Then, based on the required amount of fertilizer, personnel adjust the position of the blocking plate 4 inside the sliding block 3 by controlling the extension and retraction of the electric push rod 5, ensuring that the blocking plate 4 appropriately blocks the fertilizer discharge hole 9, thereby controlling the fertilizer discharge flow rate. The servo motor 11 is started through the control panel 14, causing the screw conveyor shaft 12 to begin rotating. The servo motor 11 is then adjusted... The rotation speed of 1 ensures that the fertilizer can be evenly delivered to the fertilizer discharge hole 9, and pushes the fertilization mechanism to move in the field. The design of the moving wheel 10 allows the fertilization mechanism to move smoothly on various terrains. During the movement, the servo motor 11 drives the screw conveyor shaft 12 to gradually push the fertilizer towards the fertilizer discharge hole 9. The fertilizer is discharged through the exposed fertilizer discharge hole 9 to achieve quantitative fertilization. After fertilization is completed, the servo motor 11 is turned off and the blocking plate 4 is returned to its initial position to completely block the fertilizer discharge hole 9. New fertilizer is added to the storage box 1 through the filling groove, and the sealing plug 7 is ensured to be firmly engaged.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
