Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, and in particular relates to a fertilizer spreader. Background Technology

[0002] In agricultural planting and production, fertilization is an essential step. Current technology generally uses manual spreading of fertilizer, which is suitable for small areas of planting land. There is also mechanized fertilization technology, but existing fertilization machinery has a complex structure and mostly uses screw conveyors or continuous mechanical fertilization, which cannot accurately adjust the amount of fertilizer according to the spacing of crop planting and growth needs, resulting in problems of over-fertilization or under-fertilization, which has a certain adverse effect on crop growth. Utility Model Content

[0003] The purpose of this utility model is to improve upon the shortcomings of existing technologies by providing a fertilizer spreader that allows for adjustable fertilizer application, intermittent fertilization, accurate and uniform fertilizer application, and has a simple structure.

[0004] The purpose of this utility model is achieved as follows: a fertilizer spreader includes a frame, a controller, and a motor. It is characterized by further including a feeding trough, a long shaft, a feeder, and a discharge plate. The feeding trough is fixed to the upper part of the frame, and the discharge plate is located at the bottom of the frame. The bottom of the feeding trough has spaced discharge ports. The two ends of the ribbed long shaft are mounted on the frame between the feeding trough and the discharge plate via bearing seats. The feeders are fixed at intervals on the frame below the feeding trough, with one feeder corresponding to each discharge port. A movable discharge regulator is provided in the discharge channel within the feeder, allowing adjustment of the discharge channel opening size. A distribution wheel is installed on the discharge channel of the feeder below the discharge regulator. The long shaft passes through the distribution wheel and drives it to rotate. A gear is installed at one end of the long shaft. A transmission gear on the output shaft of the motor, fixed to the frame, connects to and drives the large gear of a tower-shaped gear. The small gear of the tower-shaped gear connects to and drives the gear on the long shaft. The tower-shaped gear is mounted on the frame.

[0005] To further achieve the purpose of this utility model, the feed trough can be an inverted trapezoid.

[0006] To further achieve the purpose of this utility model, the discharge regulator can be in the shape of an arc plate.

[0007] To further achieve the purpose of this utility model, a hook may be provided on one side of the frame.

[0008] To further achieve the purpose of this utility model, the discharge plate can be inclined.

[0009] To further achieve the purpose of this utility model, the controller may include a remote control for controlling the motor start / stop and speed adjustment functions.

[0010] Compared with existing technologies, this utility model has the following significant features and positive effects: This utility model adopts an intermittently set feeder, which, through the cooperation of the feed chute and the discharge plate, allows for intermittent fertilization to meet the needs of intermittent fertilization and save fertilizer. An adjustable-speed motor and a long shaft drive the distribution wheel to rotate, conveying fertilizer to the discharge plate, enabling fast or slow feeding. Simultaneously, the discharge regulator, in the shape of an arc plate, is movably installed on the feeder's discharge channel. The size of the discharge channel can be adjusted by pulling the regulator to the insertion depth, adapting to different fertilization amounts and time intervals, thus meeting the needs of different fertilization amounts. A scale on the outer surface of the discharge regulator accurately displays the pulling depth, allowing for accurate indication of the discharge channel's opening degree. The feed chute is an inverted trapezoid, ensuring fertilizer can smoothly enter the feeder. The discharge plate is inclined, with its height gradually decreasing from the ground towards the fertilization side, ensuring fertilizer can be smoothly spread onto the field.

[0018] A fertilizer spreader, as shown in the reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The system includes a frame 1, a controller 4, a motor 7, a feed trough 8, a long shaft 3, a feeder 2, and a discharge plate 12. The controller 4 is mounted on the frame 1 and is used to control the motor 7. A remote controller is used for remote control. The feed trough 8 is fixed to the upper part of the frame 1 and is an inverted trapezoid. The bottom of the feed trough 8 has discharge ports spaced apart. The discharge plate 12 is fixedly mounted to the bottom of the frame 1 and is inclined, meaning its height from the ground gradually decreases from the inside towards the fertilization side to ensure the fertilizer is properly distributed. The long shaft 3 slides smoothly down, and its two ends are mounted on the bracket 1 between the feed trough 1 and the discharge plate 13 via bearing seats 5. The long shaft 3 is a hexagonal long shaft 3. The feeders 2 are fixed at intervals on the frame 1 below the feed trough 8. One feeder 2 is set below each discharge port. The feeder 2 has a vertically penetrating discharge channel. The discharge regulator 6 is movably inserted into the feeder 2 and can close the discharge channel. The discharge regulator 6 can be inserted and removed left and right. The opening degree of the feeding channel is controlled by a gear-shaped distributing wheel 14 movably mounted on the feeding channel of the feeder below the discharge regulator 6. A long shaft 3 passes through the distributing wheel 14 and drives it to rotate, thus conveying fertilizer to the discharge plate 12. The opening degree of the feeding channel is adjusted by moving the discharge regulator 6 left and right, thereby adjusting the amount of fertilizer applied. A scale is provided on the outer surface of the discharge regulator 6 to accurately display the insertion depth into the feeder 2, allowing for accurate measurement of the feeding channel opening degree. A gear 9 is mounted at one end of the long shaft 3. A transmission gear 13 on the output shaft of the motor 7, fixed to the frame 1, connects to and drives the large gear of the tower gear 10. The small gear of the tower gear 10 connects to and drives the gear 9 on the long shaft 3. The tower gear 10 is mounted on the frame, thus enabling the motor to drive the long shaft 3 to rotate via the transmission gear 13, tower gear 10, and gear 9. The discharge regulator 6 adopts an arc plate shape, as shown in the reference... Figure 6 The gear-shaped distribution wheel 14 can be well concealed to accommodate adjustments in fertilizer application rates, meeting the needs of different fertilizer application amounts. The number of teeth on the gear-shaped distribution wheel 14 determines the fertilizer application interval and amount; more teeth result in a shorter application interval and a correspondingly smaller amount of fertilizer applied each time. A hook 11 is provided on one side of the frame 1, allowing the fertilizer spreader to be suspended from external power machinery, such as an electric tricycle. In this invention, fertilizer stored in the feed trough 8 falls from the feed inlet into the distribution wheel 14 in the feeder 2. As the long shaft 3 drives the distribution wheel 14 to rotate, the fertilizer is conveyed to the discharge plate 12.
