[0002] In agricultural planting, the use of fertilization devices for quantitative fertilization allows for precise control of fertilizer application based on crop nutrient requirements and soil fertility, avoiding excessive waste or insufficient application and improving fertilizer utilization. These devices are equipped with variable speed functions, allowing for dynamic adjustment of the fertilizer application rate according to crop needs, soil conditions, and the operating environment, preventing uneven fertilization due to speed variations. When using a front-and-back grouped stratified fertilization method, the fertilizer storage tank needs to discharge fertilizer from two locations, allowing it to reach both deep and shallow soil layers. This stratified fertilization method establishes a comprehensive nutrient supply system, enabling precise nutrient delivery and improving fertilizer utilization. Therefore, there is an urgent need for a device that allows for adjustable fertilizer discharge speeds from both locations during stratified fertilization. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0018] Example 1

[0019] Please see Figure 1-12This utility model provides a technical solution: a variable-speed quantitative fertilization speed adjustment component, including a fertilizer storage box 1, a fertilizer discharge box 2, and two fertilizer delivery components 3. The fertilizer delivery component 3 includes a feeding disc 31 and a rotary driver 32. The feeding disc 31 has a first notch 311 and a second notch 312 at both ends. A fertilizer delivery pipe 21 is located on the bottom surface of the fertilizer discharge box 2, directly below the feeding disc 31. Fertilizer in the fertilizer storage box 1 first enters the fertilizer discharge box 2, and then is delivered into the two fertilizer delivery pipes 21 by the two fertilizer delivery components 3. By aligning the outlets of the two fertilizer delivery pipes 21 with the positions of the shallow and deep soil layers during stratified fertilization, fertilizer can be applied to both locations simultaneously. The width of the second notch 312 is different from the shape of the first notch 311, therefore the amount of fertilizer entering the first notch 311 and the second notch 312 is different. The rotary driver 32 consists of a servo motor and a drive rod. The feeding disc 31 is fixedly mounted in the middle of the drive rod, and the output end of the servo motor is connected to the drive rod. The servo motor can drive the drive rod to rotate continuously clockwise or counterclockwise, and it can also drive the drive rod to rotate and oscillate back and forth. Therefore, the drive rod can drive the material feeding plate 31 to rotate continuously clockwise or counterclockwise, or drive the material feeding plate 31 to rotate and oscillate back and forth.

[0020] Please see Figure 1 and Figure 5-7 When the rotary drive 32 drives the feeding disc 31 to rotate back and forth between the first and second positions, the fertilizer in the fertilizer discharge box 2 can first enter through the first notch 311. After the feeding disc 31 rotates, the fertilizer in the first notch 311 is sent into the fertilizer delivery pipe 21 and discharged. Since the feeding disc 31 rotates back and forth, the second notch 312 will not send fertilizer into the fertilizer delivery pipe 21 at this time.

[0021] Please see Figure 1 and Figure 8-10 When the rotary drive 32 drives the feeding disc 31 to reciprocate between the third and fourth positions, the fertilizer in the fertilizer discharge box 2 can first enter through the second notch 312. After the feeding disc 31 rotates, the fertilizer in the second notch 312 is sent into the fertilizer delivery pipe 21 and discharged. Since the feeding disc 31 is reciprocating, the first notch 311 will not send fertilizer into the fertilizer delivery pipe 21 at this time.

[0022] Please see Figure 1 and Figure 5-10 When the servo motor's speed increases or decreases, the speed at which fertilizer enters the fertilizer delivery pipe 21 will increase or decrease accordingly, thus adjusting the speed at which fertilizer is discharged from the two positions during stratified fertilization. Since the feeding discs 31 on both sides are controlled by two independent rotary drives 32, the task of conveying fertilizer by the first notch 311 or the second notch 312 can be changed at will, allowing the amount of fertilizer entering the shallow and deep soil layers to be adjusted as needed.

[0023] Example 2

[0024] Please see Figure 1 and Figure 4-6 Both the first notch 311 and the second notch 312 are arc-shaped notches. The width of the second notch 312 is greater than the width of the first notch 311, and the depth of the second notch 312 is greater than the depth of the first notch 311. Therefore, the second notch 312 can hold a greater amount of fertilizer than the first notch 311. When the first notch 311 and the second notch 312 are rotated to the position where the opening faces downward, all the fertilizer entering the first notch 311 and the second notch 312 quickly enters the fertilizer delivery pipe 21.

[0025] Please see Figure 1-2 and Figure 4-6 The fertilizer storage box 1 has a first fertilizer inlet 11 on its bottom surface, and the fertilizer discharge box 2 has a second fertilizer inlet 22 on its top surface, with the second fertilizer inlet 22 corresponding to the first fertilizer inlet 11. Fertilizer in the storage box 1 passes sequentially through the first fertilizer inlet 11 and the second fertilizer inlet 22, and then enters the fertilizer discharge box 2. There are several fertilizer discharge boxes 2, evenly spaced along the length of the storage box 1. Since there are several fertilizer discharge boxes 2, there are also several first fertilizer inlets 11 and several second fertilizer inlets 22. Each fertilizer discharge box 2 corresponds to a specific ridge on the ground; therefore, when performing layered fertilization, this invention can simultaneously fertilize the interior of multiple ridges.

[0026] Please see Figure 1-6 Inside the fertilizer storage box 1, between two adjacent first fertilizer inlets 11, there is a partition 4. The side wall of the partition 4 has several through slots 41, evenly spaced from top to bottom. The partitions 4 divide the interior of the fertilizer storage box 1 into multiple fertilizer storage spaces. When a fertilizer delivery component 3 malfunctions, the fertilizer in its corresponding storage space will be significantly more than in the two adjacent storage spaces. The fertilizer in the storage space corresponding to the malfunctioning component 3 will then overflow into the storage spaces on both sides through the through slots 41, facilitating timely detection and repair by the operator.

[0027] Example 3

[0028] Please see Figure 1-6This utility model also includes two guide members 5, both of which are located inside the fertilizer discharge box 2. The cross-section of each guide member 5 is triangular, and its narrow end is hinged to the inner bottom surface of the fertilizer discharge box 2. When fertilizer from the storage box 1 enters the fertilizer discharge box 2, the fertilizer quickly separates along the top inclined surfaces of the two guide members 5 and slides down to the positions of the feeding discs 31 on both sides. When all the fertilizer from the storage box 1 has entered the fertilizer discharge box 2, the fertilizer in the discharge box 2 may adhere to the top inclined surfaces of the guide members 5 and remain stationary due to friction. At this time, the two guide members 5 are driven to rotate around their narrow ends, increasing the inclination of the inclined surfaces of the guide members 5, allowing the fertilizer on the top inclined surfaces of the guide members 5 to continue sliding downwards.

[0029] Please see Figure 1-12 The bottom of the second end of the guide member 5 is provided with a storage groove 51, and an adjustment component 6 is provided between the two storage grooves 51. The adjustment component 6 can replace the human hand and drive the two guide members 5 to rotate simultaneously. The adjustment component 6 includes a transmission block 61 and a translation driver 62. The translation driver 62 includes a bidirectional electric telescopic rod 621, two sliders 622, and two adjustment links 623. When the output end of the bidirectional electric telescopic rod 621 is at its maximum extension state, the tilt state of the two adjustment links 623 is at its minimum, and the adjustment links 623 drive the transmission block 61 to move downward to the lowest point, and the two guide members 5 do not rotate. When the output end of the bidirectional electric telescopic rod 621 is at its minimum shortened state, the tilt state of the two adjustment links 623 is at its maximum, and the adjustment links 623 drive the transmission block 61 to move upward to the highest point. During the upward movement of the transmission block 61, the transmission block 61 contacts the top inner wall of the two storage grooves 51 and lifts the two guide members 5, so that the fertilizer on the top inclined surface of the guide member 5 can continue to slide downward.

[0030] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
