Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5As shown, a portable electric fertilizer applicator includes a base plate 100, on which a pressure sensor 101 is mounted. A support frame 102 is fixedly connected to the upper end of the pressure sensor 101, and a fertilizer loading box 200 is fixedly connected to the upper end of the support frame 102. The discharge port at the lower end of the fertilizer loading box 200 passes through a through hole 103 on the base plate 100. A uniform dispensing mechanism is provided at the discharge port at the lower end of the fertilizer loading box 200, and the uniform dispensing mechanism is equipped with an adjusting component for adjusting the amount of fertilizer applied. A uniform spreading module is provided at the lower end of the base plate 100. The uniform dispensing mechanism ensures uniform fertilization and improves fertilization quality by achieving uniform dispensing. The adjusting component adjusts the amount of fertilizer delivered at one time, and the uniform spreading module evenly spreads the fertilizer, ensuring uniform fertilization and improving fertilization quality.

[0026] In this embodiment, as Figure 3 As shown, the uniform discharge mechanism includes a rotating roller 301, which is rotatably connected to the discharge port of the fertilizer tank 200. The rotating roller 301 is fixedly connected to the output end of a motor 302, which is fixedly connected to the fertilizer tank 200. The rotating roller 301 is provided with six discharge troughs 303. When the motor 302 is started, it drives the rotating roller 301 to rotate. After the fertilizer fills the discharge troughs 303, it is discharged from below, completing the uniform discharge, ensuring uniform fertilization and improving the quality of fertilization.

[0027] In one embodiment, such as Figure 4 As shown, the adjusting component includes a sliding cylinder 401 and six adjusting sliders 402. The sliding cylinder 401 is slidably connected to a corresponding sliding groove 403 on the rotating roller 301. The six adjusting sliders 402 are slidably connected to six feeding troughs 303 respectively. The sliding cylinder 401 and the six adjusting sliders 402 are fixedly connected to a connecting plate 404. A telescopic rod 405 is fixedly connected to the sliding cylinder 401. The output rod of the telescopic rod 405 is fixedly connected to the inner wall of the sliding groove 403. The fertilizer box 200 is provided with grooves corresponding to the sliding cylinder 401 and the six adjusting sliders 402. When the telescopic rod 405 retracts its output rod, it drives the sliding cylinder 401 to slide into the sliding groove 403. The sliding cylinder 401 drives the six adjusting sliders 402 to slide into the six feeding troughs 303 respectively through the connecting plate 404, making the size of the feeding troughs 303 smaller, thereby reducing the amount of fertilizer conveyed and preventing an increase in the amount of fertilizer conveyed when the telescopic rod 405 extends its output rod.

[0028] In one embodiment, such as Figure 5As shown, the uniform material spreading module includes an L-shaped fixing frame 501, which is fixedly connected to the lower end of the base plate 100. A rotating disk 502 is rotatably connected to the L-shaped fixing frame 501. The output shaft of a second motor 503 is fixedly connected to the rotating disk 502, and the second motor 503 is fixedly connected to the L-shaped fixing frame 501. A limiting rod 504 is fixedly connected to the rotating disk 502. A moving rod 505 is slidably connected to the L-shaped fixing frame 501, and a fixing plate 506 is vertically fixedly connected to the middle of the moving rod 505. The fixed plate 506 is provided with a limiting groove 507, which is slidably connected to the limiting rod 504. The two ends of the moving rod 505 are fixedly connected to the spreading disc 508. When the motor 503 is started, the motor 503 drives the rotating disc 502 to rotate, the rotating disc 502 drives the limiting rod 504 to rotate, the limiting rod 504 drives the fixed plate 506 to move back and forth left and right, the fixed plate 506 drives the moving rod 505 to move back and forth left and right, and the moving rod 505 drives the spreading disc 508 to move back and forth left and right, thereby spreading the fertilizer evenly.

[0029] In one embodiment, such as Figure 1 As shown, two support plates 601 are fixedly connected to one side of the lower end of the base plate 100. Movable wheels 602 are rotatably connected to the two support plates 601. Two support columns 603 are fixedly connected to the lower end of the base plate 100 away from the movable wheels 602. Universal wheels 604 are fixedly connected to the lower ends of the two support columns 603. The movable wheels 602 and universal wheels 604 facilitate the movement of the device in the field by the workers and make it easy to move from one ridge to another.

[0030] In one embodiment, such as Figure 2 As shown, a control box 701 is provided on the upper end of the base plate 100. A controller 702 is provided on the control box 701. The controller 702 is electrically connected to the pressure sensor 101, the motor 302, and the telescopic rod 405. A storage battery 703 is provided in the control box 701. The storage battery 703 is electrically connected to the controller 702. The speed of the motor 302 is controlled by the control box 701, thereby controlling the discharge speed of the device. The extension and retraction of the output rod of the telescopic rod 405 is controlled by the control box 701, thereby controlling the size of the discharge port. Thus, the size of the discharge port or the frequency of discharge can be adjusted according to the deviation between the actual amount of fertilizer and the set amount of fertilizer. Using the storage battery as a power source avoids the pollution of farmland and air caused by diesel combustion and mechanical oil leakage, which is beneficial to the protection of the environment and human health.

[0031] In one embodiment, such as Figure 1As shown, a walking distance measuring instrument 800 is fixedly connected to the support plate 601. The walking distance measuring instrument 800 is electrically connected to the controller 702. The walking distance measuring instrument 800 records the distance traveled by the device in real time. The weight of the remaining fertilizer is continuously measured by the pressure sensor 101, and the data is transmitted to the controller 702. The controller 702 calculates the actual amount of fertilizer applied based on the distance traveled by the device and the weight of the remaining fertilizer. If a deviation is found between the actual amount of fertilizer applied and the set amount of fertilizer applied, the controller 702 will automatically control the adjusting component to adjust the size of the fertilizer outlet and control the frequency of the uniform discharge mechanism.

[0032] In one embodiment, such as Figure 1 As shown, a handle 900 is fixedly connected to the upper end of the base plate 100. The handle 900 facilitates the push of the device by the staff, thereby increasing the staff's work efficiency.

[0033] The above embodiment discloses a portable electric fertilization device. Before fertilization, fertilizer is loaded into the fertilizer tank 200, and the initial weight of the fertilizer is measured by the pressure sensor 101. The total amount of fertilizer required for this fertilization is set according to the ridge length of the farmland to be fertilized and the fertilization plan. The operator pushes the device across the farmland, and the distance traveled is recorded in real time by the distance measuring instrument 800. As the device moves, motor 1 302 drives the rotating roller 301 to rotate. After the fertilizer fills the discharge trough 303, it is discharged from below. Motor 2 503 drives the rotating disk 502 to rotate, which in turn drives the limiting rod 504 to rotate. The limiting rod 504 drives the fixed plate 506 to reciprocate left and right, which in turn drives the moving rod 505 to reciprocate left and right. The spreading disc 508 reciprocates left and right to evenly spread the fertilizer. During fertilization, the pressure sensor 101 continuously measures the weight of the remaining fertilizer and transmits the data to the controller 702. The controller 702 calculates the actual amount of fertilizer applied based on the distance the device has traveled and the weight of the remaining fertilizer. If a deviation is found between the actual amount of fertilizer applied and the set amount, the controller 702 will automatically control the telescopic rod 405 to extend or retract the output rod, causing the sliding cylinder 401 to slide in the sliding groove 403. The sliding cylinder 401 drives the six adjusting sliders 402 to slide in the six discharging troughs 303 respectively through the connecting plate 404, changing the size of the discharging troughs 303 and thus changing the amount of fertilizer conveyed at one time. The controller 702 then controls the speed of the motor 302 to adjust the frequency of discharging.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
