[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 fertilizer applicator with adjustable feeding speed includes an electric base 1. A distance measuring instrument 11 is fixedly connected to the left side of the upper surface of the electric base 1. A rotating seat 12 is rotatably connected to the middle of the upper surface of the electric base 1. A handle 13 is fixedly connected to the right side of the upper surface of the rotating seat 12. Guide blocks 14 are evenly distributed at the bottom of the rotating seat 12. The outer wall of the guide block 14 is slidably connected to a groove opened at the top of the electric base 1. A support frame 15 is fixedly connected to the top of the rotating seat 12. A control mechanism 2 is fixedly connected to the top of the support frame 15.

[0026] By cooperating with the control mechanism 2 and the feeding mechanism 3, the fertilization speed can be controlled, thereby controlling the amount of fertilizer applied. During the fertilization process, the entire device can be easily moved by manually holding the handle 13 and using the electric base 1. The distance measuring instrument 11 can determine the distance traveled by the entire device during the fertilization process, thereby extending the fertilization effect and preventing the end of the field ridge from being left unfertilized.

[0027] In an optional embodiment, such as Figures 1-5 As shown, the guide block 14 is T-shaped, and the groove on the top of the electric base 1 is adapted to the shape of the guide block 14. When the device needs to turn around at the end of the ridge, the switch of the rotating seat 12 can be activated, so that the rotating seat 12 drives the guide block 14 to rotate on the inner wall of the electric base 1, thereby completing the turning. Then the device can be moved to another ridge, which is more convenient.

[0028] In an optional embodiment, such as Figures 2-4As shown, the control mechanism 2 includes a circular frame 201. The outer wall of the circular frame 201 is fixedly connected to the top of the support frame 15. A discharge port 213 is fixedly connected to the bottom of the circular frame 201. A solenoid valve is fixedly connected to the bottom of the inner wall of the discharge port 213. A stepper motor 202 is fixedly connected to the front of the circular frame 201. A circular block 203 is fixedly connected to the output end of the stepper motor 202 through the outer wall of the circular frame 201. Observation windows are provided on the outer walls of the circular frame 201 and the circular block 203. The outer wall of the circular block 203 is connected to the outer wall of the circular frame 201. The inner wall of the circular block 203 is slidably connected. A motor 205 is fixedly connected to the inner wall of the circular block 203. A driving bevel gear 206 is fixedly connected to the output end of the motor 205. A driven bevel gear 207 meshes with the front part of the driving bevel gear 206. A bidirectional threaded rod 208 is fixedly connected to the axis of the driven bevel gear 207. Slider 209s are threadedly connected to both the left and right sides of the outer wall of the bidirectional threaded rod 208. Movable rods 210 are rotatably connected to both the upper and lower parts of the slider 209. A support rod 211 is rotatably connected to the top of the movable rod 210. The outer wall of the support rod 211 is slidably connected to the inner wall of the circular block 203. The top of the support rod 211 is fixedly connected to the electronic scale 212. The outer wall of the electronic scale 212 is slidably connected to the top of the circular block 203. The top of the circular frame 201 is provided with a feeding mechanism 3. The motor 205 drives the active bevel gear 206 and the driven bevel gear 207 to mesh, so that the driven bevel gear 207 drives the bidirectional threaded rod 208 to rotate, so that the slider 209 moves on the outer wall of the bidirectional threaded rod 208, which drives the movable rod 210 to rotate, so that the movable rod 210 drives the support rod 212. 1. The circular block 203 moves along the inner wall, and the support rod 211 drives the electronic scale 212 to move along the inner wall of the feeding trough. Observation through the observation window shows that when the electronic scale 212 is in a suitable position in the feeding trough, the material can be fed through the feeding mechanism 3. When the weight of fertilizer on the electronic scale 212 reaches the threshold, the stepper motor 202 starts, driving the circular block 203 to rotate, so that the feeding trough that has received a sufficient amount of fertilizer rotates 180°, connecting it with the discharge port 213, thereby conveying the fertilizer into the discharge port 213, and then the fertilization work can begin.

[0029] In an optional embodiment, such as Figure 2 As shown, a limiting ring 204 is fixedly connected to the outer wall of the circular block 203. The outer wall of the limiting ring 204 is slidably connected to the inner wall of the circular frame 201. The circular block 203 drives the limiting ring 204 to slide on the inner wall of the circular frame 201. The limiting ring 204 restricts the circular block 203 to prevent it from deviating during rotation.

[0030] In an optional embodiment, such as Figure 2 and Figure 3As shown, the circular block 203 has material discharge grooves on both the upper and lower parts, and the size of the material discharge grooves is adapted to the size of the electronic scale 212. Through the material discharge grooves on the outer wall of the circular block 203, the electronic scale 212 can more conveniently receive and weigh fertilizer.

[0031] In an optional embodiment, such as Figure 3 As shown, the inner diameter of the material discharge groove on the outer wall of the circular block 203 is larger than the diameter of the discharge port 213, and the diameter of the discharge port 213 is smaller than the inner diameter of the material discharge groove. This can prevent the discharge port 213 from working with the solenoid valve inside it during the rotation of the material discharge groove, so that there is still fertilizer in the discharge port 213 and fertilization can continue without any fertilizer gap.

[0032] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the feeding mechanism 3 includes a feeding pipe 301 with a feeding port at the top. A feeding pipe 306 is fixedly connected to the bottom of the feeding pipe 301. The bottom of the feeding pipe 306 is fixedly connected to the top of the circular frame 201. A fixed frame 302 is fixedly connected to the top of the feeding pipe 301. A second motor 303 is installed inside the fixed frame 302. A rotating rod 304 is fixedly connected to the output end of the second motor 303 through the outer wall of the top of the feeding pipe 301. A spiral blade 305 is fixedly connected to the bottom of the outer wall of the rotating rod 304. The outer wall of the spiral blade 305 contacts the inner cavity of the feeding pipe 306. By adjusting the speed of the second motor 303, the rotation speed of the rotating rod 304 and the spiral blade 305 driven by the second motor 303 is fixed, thereby fixing the amount of fertilizer conveyed downward by the spiral blade 305 each time. At the same time, the fertilizer conveyed downward by the spiral blade 305 is conveyed to the dropping groove opened on the outer wall of the circular block 203 through the feeding pipe 306.

[0033] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the feed pipe 301, the discharge pipe 306 and the material chute on the outer wall of the circular block 203 are interconnected. Through the interconnection between the feed pipe 301, the discharge pipe 306 and the material chute, fertilizer can be continuously transported to the discharge port 213.

[0034] The above embodiment discloses a fertilizer applicator with adjustable feeding speed. The entire device can be easily moved by a person holding the handle 13, in conjunction with the electric base 1. When fertilizing crops, the required amount of fertilizer is first calculated based on the size of the land to be fertilized. Then, the fertilizer is poured into the feed pipe 301. Motor 205 drives the active bevel gear 206 and the driven bevel gear 207 to mesh, causing the driven bevel gear 207 to rotate the bidirectional threaded rod 208. This causes the slider 209 to move on the outer wall of the bidirectional threaded rod 208, rotating the movable rod 210. The movable rod 210 then drives the support rod 211 to move on the inner wall of the circular block 203. The support rod 211 then drives the electronic scale 212 to move on the inner wall of the feed trough. The process is observed through the observation window. Once the electronic scale 212 is in the appropriate position within the feeding chute, motor 1 205 can be turned off. Then, the speed of motor 2 303 is adjusted to maintain a fixed speed at which motor 2 303 drives the rotating rod 304 and the spiral blade 305, thus ensuring a fixed amount of fertilizer is conveyed downwards by the spiral blade 305 each time. Simultaneously, the fertilizer conveyed downwards by the spiral blade 305 is transported through the feeding pipe 306 to the feeding chute on the outer wall of the circular block 203. The electronic scale 212 in the feeding chute weighs the falling fertilizer. When the weight reaches a preset threshold, motor 2 303 stops working, and no more fertilizer falls. At the same time, stepper motor 202 starts, driving the circular block 203 to rotate, and the circular block 203 moves to a limit position. Ring 204 slides on the inner wall of circular frame 201, causing the trough containing a sufficient amount of fertilizer to rotate 180° and connect with outlet 213, thereby conveying fertilizer into outlet 213. Fertilization can then begin. By opening the solenoid valve on the inner wall of outlet 213, a certain opening is created, allowing fertilizer to continuously fall into the field. Simultaneously, motor 303 resumes operation, conveying fertilizer to the empty trough. When sufficient fertilizer is refilled, the above operation is repeated, causing the fertilizer-filled trough to rotate 180° and connect with outlet 213, continuing fertilization. During this process, because the solenoid valve on the inner wall of outlet 213 is not fully open during the rotation of circular block 203, the outlet is controlled. The fertilizer feeding speed in 213 is such that when the circular block 203 stops rotating, the fertilizer in the outlet 213 is just used up. At this time, the fertilizer-filled trough is connected to the outlet 213, thus preventing any gaps in fertilizer application and ensuring more even fertilization. In summary, by cooperating with the control mechanism 2 and the feeding mechanism 3, the fertilization speed can be controlled, thereby controlling the amount of fertilizer applied. During fertilization, the entire device can be easily moved by manually holding the handle 13 and using the electric base 1. The distance measuring instrument 11 can determine the distance traveled by the entire device during fertilization, thus extending the fertilization effect and preventing the end of the field ridge from being left unfertilized.

[0035] 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.
