Description

Technical Field

[0001] This utility model relates to the field of fertilization device technology, and in particular to a crop root fertilization device for agricultural planting. Background Technology

[0002] Agricultural crop fertilization devices are mechanical devices specifically designed for fertilizing farmland, aiming to improve fertilization efficiency and accuracy. These devices typically include components such as storage tanks, transmission tanks, and control mechanisms, enabling quantitative application of fertilizer to meet the growth needs of crops and reduce fertilizer waste.

[0003] A search revealed that most existing agricultural fertilization methods rely on manual labor, resulting in low efficiency. Furthermore, manual fertilization is inadequate in controlling fertilizer emissions and often fails to achieve precise quantification. This leads to fertilizer waste or overuse during actual fertilization, increasing agricultural production costs and potentially harming soil ecology and crop health. Therefore, this paper proposes a root fertilization device for agricultural crops to address these issues. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1 to 6In this embodiment of the present invention, a crop root fertilization device for agricultural planting includes: a base handcart 1, a liquid fertilizer storage tank 2 fixedly connected above the base handcart 1, a turntable 3 rotatably connected above the base handcart 1, two sets of side rotating arms 4 rotatably connected above the turntable 3, and a set of limiting extension frames 5 rotatably connected to the other end of each of the two sets of side rotating arms 4; a first drive motor 6 fixedly connected below the base handcart 1, the rotation shaft of the first drive motor 6 passing through the middle support plate of the base handcart 1 and fixed to the turntable 3. The base trolley 1 is connected to two sets of extension frame limiting blocks 7, which are adapted to the limiting extension frame 5, restricting the limiting extension frame 5 to move back and forth only along the line connecting the two sets of limiting extension frames 5. The limiting extension frame 5 is fixedly connected to a fixing block 8 below it, and a fertilizer dispensing mechanism 9 is fixedly connected to the inner side of the fixing block 8. The liquid fertilizer storage tank 2 is fixedly connected to both sides with telescopic hoses 10. The base trolley 1 is fixedly connected to an upper protective shell 11 to protect the turntable 3 and the side rotating arm 4 and other structures.

[0026] When the turntable 3 is driven to rotate by the first drive motor 6, it drives the two sets of side rotating arms 4 to expand or retract synchronously. The limiting extension frame 5 connected to the end of the side rotating arm 4 achieves horizontal telescopic movement under the linear guidance of the extension frame limiting block 7, thereby accurately adjusting the lateral distance between the two fertilizer quantitative dispensing mechanisms 9. The turntable 3 completes one expansion or retraction action every 90° of rotation. The two fertilizer quantitative dispensing mechanisms 9 can simultaneously perform synchronous root fertilization of two rows of crops. The telescopic hose 10 adopts a corrugated pipe structure and can automatically adjust its length with the telescopic movement of the limiting extension frame 5 to ensure the continuity of liquid delivery.

[0027] The fertilizer dispensing mechanism 9 includes a funnel cylinder 91, an open cover 92 on the top of the funnel cylinder 91, an upper open baffle 93 fixedly connected to the inside of the funnel cylinder 91, a lower open baffle 94 rotatably connected below the upper open baffle 93, a second drive motor 95 fixedly connected below the lower open baffle 94, the rotation shaft of the second drive motor 95 passes through the lower open baffle 94 and is fixedly connected to the upper open baffle 93, a liquid outlet pipe 96 is threadedly connected to the bottom of the funnel cylinder 91, one end of the telescopic hose 10 passes through the inside of the liquid fertilizer storage tank 2, and the other end is threadedly connected to the open hole on the inside of the open cover 92. The bottom of the liquid fertilizer storage tank 2 is designed with a slope to facilitate the flow of internal liquid to the front of the inner cavity that is connected to the telescopic hose 10. In the working state, the height of the open cover 92 is slightly lower than the bottom height of the liquid fertilizer storage tank 2.

[0028] When the second drive motor 95 drives the upper perforated baffle 93 to rotate relative to the lower perforated baffle 94, the flow rate is controlled by adjusting the overlap of the openings of the two sets of perforated baffles. When they are completely overlapped, the maximum flow cross section is formed. When they are misaligned, the flow rate is gradually reduced until it is completely closed. The inclined design of the liquid fertilizer storage tank 2 allows the liquid to be automatically replenished to the funnel cylinder 91 under the action of gravity. When the openings of the upper perforated baffle 93 and the lower perforated baffle 94 are aligned, the quantitative discharge is completed. The angle of rotation and the dwell time of each rotation correspond to a specific discharge volume. The threaded connection structure of the liquid outlet pipe 96 allows for quick replacement of drip irrigation heads with different orifice diameters to adapt to the fertilizer flow rate requirements of different crops.

[0029] The working principle of this utility model is as follows: First, in the preparation stage, the device is moved to the farmland area that needs to be fertilized, ensuring that the base handcart 1 is parked stably. According to the row spacing of the crop, the rotation angle of the first drive motor 6 is adjusted to control the rotation of the turntable 3, so that the two sets of side rotating arms 4 drive the limit extension frame 5 to unfold to a suitable lateral spacing. This spacing should ensure that the fertilizer quantitative dispensing mechanism 9 can accurately align with the root position of the crop.

[0030] Check that the telescopic hose 10 is securely connected to ensure that the liquid fertilizer can be smoothly delivered from the liquid fertilizer storage tank 2 to the fertilizer dispensing mechanism 9;

[0031] Open the filling port of the liquid fertilizer storage tank 2 and pour an appropriate amount of liquid fertilizer into the storage tank. Since the bottom of the liquid fertilizer storage tank 2 is designed to be inclined, the liquid fertilizer will automatically flow to the front of the inner cavity that is connected to the telescopic hose 10 under the action of gravity, ensuring that the funnel 91 can continuously receive liquid fertilizer.

[0032] Based on the fertilization needs of the crop and soil conditions, the rotation angle and dwell time of the second drive motor 95 are set to control the overlap of the openings of the upper opening baffle 93 and the lower opening baffle 94, thereby achieving precise flow control. As needed, the drip head on the outlet pipe 96 is replaced to adapt to the different crop requirements for fertilization flow rate.

[0033] When fertilization begins, the second drive motor 95 is activated, causing the upper perforated baffle 93 to rotate relative to the lower perforated baffle 94 to the preset perforation overlap, and liquid fertilizer is discharged in a metered manner. According to the set residence time, the second drive motor 95 stops rotating after completing the metered discharge at each location. At this time, the perforations of the upper perforated baffle 93 and the lower perforated baffle 94 are misaligned, cutting off the flow of liquid fertilizer. The above steps are repeated until the fertilization operation of the entire farmland area is completed.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
