Description
Technical Field
[0001] This utility model relates to the field of vegetable fertilization technology, and in particular to a precision fertilization control device for vegetables. Background Technology
[0002] Existing vegetable fertilization devices are inconvenient for precise control of fertilizer application. Base fertilizer is the foundation for vegetable growth, ensuring nutrients from seedlings to mature plants. Sufficient base fertilizer should be applied, combining organic and chemical fertilizers, avoiding the use of a single fertilizer. Organic fertilizer should generally be no less than 3 cubic meters, and chemical fertilizers should be a balanced mix of nitrogen, phosphorus, and potassium, typically around 80 jin (40 catties) per mu (0.067 hectares) for compound fertilizer. These fertilizers should be applied to the soil at least 15 days before transplanting or sowing. Base fertilizer can be applied in three ways: broadcasting, hole application, and strip application. Hole application involves placing the base fertilizer in pits dug according to row and plant spacing before planting, or digging pits two to three inches away from the crop roots during crop growth and applying the fertilizer. This method is highly targeted and has a high nutrient utilization rate, ensuring rapid and accurate absorption of nutrients by the crop roots through direct application near the root system. Hole application typically uses mechanical tools to assist in digging the pits and applying the fertilizer.
[0003] A granular fertilizer applicator disclosed in Chinese patent document CN2453657Y features a spring seat on a fertilizer tube, a spring mounted on the spring, a sliding sleeve below the spring, and a telescopic frame mounted on the sliding sleeve. This allows for direct application of fertilizer to the plant roots with accurate dosage. It boasts a simple structure, ease of use, durability, and saves time and labor. It can operate upright, eliminating the need for strenuous work involving bending over and crawling on the ground. It is not limited by row or plant spacing and is suitable for plains, mountains, and greenhouses. While proven to be an ideal new agricultural tool worthy of widespread use, this granular fertilizer applicator lacks a suitable force application point, making it inconvenient to drive the applicator into the soil for fertilization.
[0004] Existing vegetable fertilization devices are not convenient for precise control of fertilizer application.
[0005] To address the shortcomings of the existing technologies, providing a precise fertilization control device for vegetables is a worthwhile research topic. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing vegetable fertilization devices in terms of the inconvenience of precise control over the amount of fertilizer applied, and to provide a precise fertilization control device for vegetables to achieve precise control over the amount of fertilizer applied.
[0007] The purpose of this utility model is achieved through the following technical solution: a precision fertilization control device for vegetables, including a fertilizer storage bin, characterized in that: a fertilizer hole opening module is fixedly connected to the bottom of the fertilizer storage bin, and a fertilizer feeding module is provided between the fertilizer storage bin and the fertilizer hole opening module.
[0008] The fertilizer application hole-opening module includes a hollow hole-opening shovel connected to the bottom of the fertilizer storage bin and a closing plate rotatably connected to the bottom opening of the hollow hole-opening shovel.
[0009] The bottom of the hollow hole-opening shovel is arc-shaped, and the shape of the closing plate is adapted to the shape of the bottom opening of the hollow hole-opening shovel. When the hollow hole-opening shovel contacts the ground to open a hole, the closing plate merges and closes with the opening of the hollow hole-opening shovel under the force of the soil. The two work together to insert into the soil layer to complete the opening. After the opening is completed, the hollow hole-opening shovel is pulled outward slightly to open the closing plate, and the fertilizer inside the hollow hole-opening shovel flows out from the gap in the opening to complete the fertilization.
[0010] A torsion spring is sleeved between the sealing plate and the pivot of the hollow shovel. The torsion of the torsion spring causes the sealing plate to open outward. After the hollow shovel enters the soil, it is pulled outward. The sealing plate can open more easily with the assistance of the torsion spring.
[0011] The fertilizer feeding module includes a closed block connected to the fertilizer storage bin and pedals fixedly connected to both ends of the closed block;
[0012] The bottom opening of the fertilizer storage silo has an isosceles trapezoidal cross-sectional shape, and the shape of the closing block is adapted to the cross-sectional shape of the bottom opening of the fertilizer storage silo.
[0013] The hollow hole-opening shovel has grooves on both sides of its top. The pedal passes through the grooves and is located on the outside of the hollow hole-opening shovel. By controlling the time the pedal is stepped on, the amount of fertilizer added into the hollow hole-opening shovel can be controlled, thereby achieving precise control of the amount of fertilizer applied in a single application.
[0014] Compression springs are fixedly connected to both sides of the inner wall of the hollow shovel. The top of the compression spring is fixedly connected to the bottom of the sealing block. The elastic force of the compression spring is greater than the sum of the weight of the sealing block and the force exerted on the sealing block by the fertilizer inside the fertilizer storage bin. After stepping on the pedal, the sealing plate can be reset and restored to the closed state in time.
[0015] A hand-held handle is fixedly connected to the rear side of the fertilizer storage silo, and the length of the hand-held handle is greater than 80 centimeters.
[0016] The fertilizer storage silo has a feeding port at the top, and the rear side of the fertilizer storage silo is flush with the rear side of the hollow hole-opening shovel to avoid the fertilizer storage silo bulging backward, which would not conform to ergonomics and affect the operator's ability to exert force to complete the hole-opening and fertilization.
[0017] Positive and beneficial effects: 1. This vegetable precision fertilization control device controls the amount of fertilizer added to the hollow hole-opening shovel by controlling the time of stepping on the pedal, thereby achieving precise control of the amount of fertilizer applied at one time. The fertilizer is then added into the prepared soil hole through the bottom opening of the hollow hole-opening shovel. This fertilization control device is simple to operate, can save effort to open holes for fertilization, and can accurately control the amount of fertilizer applied.
[0018] 2. This precision fertilization control device for vegetables has an arc-shaped bottom for the hollow hole-opening shovel. This means that the height of the two sides of the sealing plate is lower than the height of the middle, allowing the fertilizer to roll down from both sides along the arc surface of the sealing plate to complete the discharge. This avoids fertilizer accumulating at the bends of the sealing plate and affecting the fertilization effect.
[0019] 3. This precision fertilization control device for vegetables restricts the rear side of the fertilizer storage bin from being flush with the hollow hole-opening shovel, preventing the fertilizer storage bin from bulging backward, which is not in line with ergonomics and affects the operator's ability to exert force to complete the hole-opening fertilization.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0029] Example 1
[0030] like Figures 1 to 7 As shown, a precision fertilization control device for vegetables includes a fertilizer storage bin 1. The device is characterized in that a fertilizer application hole module is fixedly connected to the bottom of the fertilizer storage bin 1, and a fertilizer feeding module is provided between the fertilizer storage bin 1 and the fertilizer application hole module.
[0031] like Figure 3 As shown, the fertilizer application hole-opening module includes a hollow hole-opening shovel 2 that is connected to the bottom of the fertilizer storage bin 1 and a closing plate 3 that is rotatably connected to the bottom opening of the hollow hole-opening shovel 2.
[0032] The bottom of the hollow shovel 2 is arc-shaped, and the shape of the sealing plate 3 is adapted to the shape of the bottom opening of the hollow shovel 2. By setting the hollow shovel 2 with the sealing plate 3 below the fertilizer storage bin 1, when the hollow shovel 2 contacts the ground to open a hole, the sealing plate 3 merges and closes with the opening of the hollow shovel 2 under the force of the soil. The two work together to insert into the soil layer to complete the opening. After the opening is completed, the hollow shovel 2 is pulled outward slightly to open the sealing plate 3, and the fertilizer in the hollow shovel 2 flows out from the gap of the opening to complete the fertilization. By setting the bottom of the hollow shovel 2 to be arc-shaped, the height of the two sides of the sealing plate 3 is lower than the height of the middle part, so that the fertilizer can roll down from the sides along the arc surface of the sealing plate 3 to complete the discharge, avoiding the accumulation of fertilizer at the bend of the sealing plate and affecting the fertilization effect.
[0033] like Figure 7 As shown, a torsion spring 4 is sleeved in the middle of the rotating shaft of the closed plate 3 and the hollow shovel 2. The torsion of the torsion spring 4 causes the closed plate 3 to open outward. By setting the torsion spring 4 on the rotating shaft of the closed plate 3, after the hollow shovel 2 digs into the soil layer, it is pulled outward. With the assistance of the torsion spring 4, the closed plate 3 can open more easily, so that fertilizer can flow out from the gap of the closed plate 3 to complete the fertilization. This avoids the situation where the closed plate 3 cannot open to complete the fertilization under the action of soil pressure.
[0034] Example 2
[0035] like Figures 1 to 5 As shown, the fertilizer feeding module includes a closed block 5 connected to the fertilizer storage silo 1 and pedals 6 fixedly connected to both ends of the closed block 5.
[0036] The bottom opening of the fertilizer storage silo 1 has an isosceles trapezoidal cross-sectional shape, and the shape of the closing block 5 is adapted to the cross-sectional shape of the bottom opening of the fertilizer storage silo 1.
[0037] The hollow shovel 2 has grooves 7 on both sides of its top. The pedal 6 passes through the grooves 7 and is located on the outside of the hollow shovel 2. A sliding sealing block 5 with the pedal 6 is set between the fertilizer storage bin 1 and the hollow shovel 2. The sealing block 5 is closed by cooperating with the bottom opening of the fertilizer storage bin 1. When it is necessary to open a hole for fertilization, the hollow shovel 2 is aligned with the ground to be opened, and the pedal 6 is stepped down. First, the sealing block 5 is disengaged from the bottom opening of the fertilizer storage bin 1, allowing fertilizer to enter the hollow shovel 2. Continuing to step on the pedal 6 will generate downward pressure on the hollow shovel 2 to complete the opening of the hole in the ground. The amount of fertilizer added to the hollow shovel 2 can be controlled by controlling the time of stepping on the pedal 6, thereby achieving precise control of the amount of fertilizer applied at one time. Then, the fertilizer is added into the opened soil hole through the bottom opening of the hollow shovel 2. This fertilization control device is simple to operate, can save effort to open holes for fertilization, and can accurately control the amount of fertilizer applied.
[0038] like Figures 4 to 5 As shown, compression springs 8 are fixedly connected to both sides of the inner wall of the hollow shovel 2. The top of the compression spring 8 is fixedly connected to the bottom of the sealing block 5. The elastic force of the compression spring 8 is greater than the sum of the weight of the sealing block 5 and the force exerted by the fertilizer inside the fertilizer storage hopper 1 on the sealing block 5. By setting the compression spring 8 at the bottom of the sealing block 5, the sealing block 5 can maintain the state of closing the bottom opening of the fertilizer storage hopper 1 under the action of elastic force. After stepping on the pedal 6, the sealing plate 5 can be reset in time to restore the closed state.
[0039] like Figure 1 As shown, a hand-held lever 9 is fixedly connected to the rear side of the fertilizer storage bin 1, and the length of the hand-held lever 9 is greater than 80 centimeters.
[0040] Example 3
[0041] like Figure 1 As shown, the top of the fertilizer storage bin 1 is provided with a feeding port. The rear side of the fertilizer storage bin 1 is flush with the rear side of the hollow hole-opening shovel 2. By limiting the rear side of the fertilizer storage bin 1 to be flush with the hollow hole-opening shovel 2, the fertilizer storage bin 1 is prevented from bulging backward, which would not conform to ergonomics and affect the operator's ability to exert force to complete the hole-opening and fertilization.
[0042] The working principle of this utility model is as follows:
[0043] S1. When the hollow shovel 2 contacts the ground to open a hole, the closing plate 3 closes with the opening of the hollow shovel 2 under the force of the soil. The two work together to insert into the soil layer to complete the opening. After the opening is completed, the hollow shovel 2 is pulled outward slightly to open the closing plate 3. The fertilizer in the hollow shovel 2 flows out from the gap of the opening to complete the fertilization.
[0044] S2. When it is necessary to open a hole for fertilization, align the hollow hole-opening shovel 2 with the ground where the hole is to be opened, step down on the pedal 6, first disengage the sealing block 5 from the bottom opening of the fertilizer storage silo 1, and let the fertilizer enter the hollow hole-opening shovel 2.
[0045] S3. Continuing to press the pedal 6 will apply downward pressure to the hollow shovel 2, thus opening a hole in the ground. By controlling the time the pedal 6 is pressed, the amount of fertilizer added to the hollow shovel 2 can be controlled, thereby achieving precise control of the amount of fertilizer applied in a single application.
[0046] S4. After pedal 6 is pressed, the sealing plate 5 can be reset and restored to the closed state in time.
