[0040] The fertilizer filtering assembly 802 is composed of a bottom bin 8021, a funnel 8022, a support plate 8023, a motor 8024, a screening net 8025, a rotating plate 8026, a traction rod 8027, a push rod 8028, a connecting piece 8029, a U-shaped tube 80210, an outer rod 80211, an output rod 80212, a toggle plate 80213, a spring push rod 80214, a knocking pad 80215, a slide rail 80216 and a slider 80217. The bottom bin 8021 is fixedly connected to the inside of the housing 1, the funnel 8022 is fixedly connected to the top of the bottom bin 8021, the support plate 8023 is fixedly connected to the top of the funnel 8022, the motor 8024 is fixedly connected to the top of the support plate 8023, the screening net 8025 is installed inside the funnel 8022, and the rotating plate 8026 is installed on the motor. At the output end of 8024, the traction rod 8027 is installed on the outer wall of the rotating plate 8026, the pushing rod 8028 is fixedly connected to the outer wall of the screening net 8025, the connecting piece 8029 is installed on the end of the pushing rod 8028 away from the screening net 8025, the U-shaped tube 80210 is fixedly connected to the outer wall of the funnel 8022, the outer rod 80211 is fixedly connected to the outer wall of the screening net 8025, the output rod 80212 is arranged inside the funnel 8022, the toggle plate 80213 is fixedly connected to the bottom of the output rod 80212, the spring push rod 80214 is arranged inside the funnel 8022, the knocking pad 80215 is fixedly connected to the inner wall of the funnel 8022, the slide rail 80216 is opened inside the funnel 8022, and the slider 80217 is fixedly connected to the outer wall of the screening net 8025.

[0041] It should be noted that: the bottom of the inner wall of the bottom bin 8021 is concave in all directions toward the center, and the fertilizer entering the bottom bin 8021 will flow under the action of the inclined inner wall of the bottom bin 8021, and the fertilizer delivery pump 803 is assisted to transport the fertilizer. The bottom of the fertilizer tank 801 is fixedly connected with an output pipe, and is connected with the funnel 8022. The inner wall of the funnel 8022 is fixedly connected with a guide plate, and the top of the screening net 8025 is fixedly connected to the bottom of the guide plate. The existence of the guide plate can ensure that the fertilizer is accumulated on the top of the screening net 8025 through the output pipe. The outer wall of the screening net 8025 is slidably connected to the inner wall of the funnel 8022, and the slider 80217 is located inside the slide rail 80216 and is slidably connected to the inner wall of the slide rail 80216. When the screening net 8025 slides inside the funnel 8022, it can drive the slider 80217 to slide inside the slide rail 80216. At the same time, the slider 80217 cooperates with the slide rail 80216 to support the screening net 8025. The end of the push rod 8028 away from the screening net 8025 penetrates the funnel 8022 and extends to the outside of the funnel 8022. The outer wall of the push rod 8028 is slidably connected with the inner wall of the funnel 8022 penetrated by the push rod 8028. The two ends of the traction rod 8027 are rotatably connected with the outer wall of the rotating plate 8026 and the connecting piece 8029 respectively. When the rotating plate 8026 rotates under the action of the motor 8024, the traction rod 8027, the connecting piece 8029 and the push rod 8028 can drive the rotating plate 8026 to rotate. The movable screening net 8025 is shaken, and one end of the outer rod 80211 away from the screening net 8025 penetrates the funnel 8022 and extends to the inside of the U-shaped tube 80210. The outer wall of the outer rod 80211 is slidably connected to the inner wall of the U-shaped tube 80210. When the screening net 8025 moves, it can push the outer rod 80211 to slide inside the U-shaped tube 80210. One end of the output rod 80212 penetrates the funnel 8022 and extends to the inside of the U-shaped tube 80210. The outer wall of the output rod 80212 is slidably connected to the inner wall of the U-shaped tube 80210. When the outer rod 80211 slides, the output rod 80212 will slide under the action of the internal air pressure of the U-shaped tube 80210, and the toggle plate 80 The bottom of 213 is serrated, and the bottom of the toggle plate 80213 contacts the top of the screening mesh 8025. When the output rod 80212 moves, the serrated toggle plate 80213 moves on the top of the screening mesh 8025, so that the material accumulated on the top of the screening mesh 8025 can be spread out. The spring push rod 80214 is located on the left front and back of the screening mesh 8025 and the right front and back of the screening mesh 8025, and is fixedly connected to the outer wall of the screening mesh 8025. When the screening mesh 8025 moves, it can push the spring push rod 80214 to move and collide with the knocking pad 80215. The impact force generated by the collision can assist the fertilizer inside the bottom bin 8021 to flow.

[0042] By arranging a screening net 8025 inside the fertilizer supply component 8 and controlling the motor 8024 to operate, the motor 8024 drives the rotating plate 8026 to rotate. Since the two ends of the traction rod 8027 are respectively connected to the rotating plate 8026 and the connecting piece 8029, when the rotating plate 8026 rotates, the traction rod 8027 drives the push rod 8028 to move back and forth through the connecting piece 8029. At this time, the push rod 8028 drives the screening net 8025 to slide back and forth inside the funnel 8022. At this time, the fertilizer accumulated on the top of the screening net 8025 will roll under the inertia generated during the movement of the screening net 8025, and will be screened through different areas of the screening net 8025, thereby accelerating the speed at which the fertilizer passes through the screening net 8025 and improving the screening efficiency of the screening net 8025.

[0043] By installing a U-shaped tube 80210 on the outer wall of the funnel 8022, when the screening net 8025 is shaken, the outer rod 80211 will be driven to slide inside the U-shaped tube 80210, and pressure will be applied to the air inside the U-shaped tube 80210. When the pressure inside the U-shaped tube 80210 changes, the output rod 80212 will drive the toggle plate 80213 to move back and forth on the top of the screening net 8025 under the action of the air pressure, and in the opposite direction of the moving trajectory of the screening net 8025. At this time, the screening net 8025 can flatten the fertilizer accumulated on the top of the screening net 8025, so that the fertilizer cannot be accumulated on the top of the screening net 8025, thereby ensuring the shaking and screening effect of the screening net 8025 on the fertilizer.

[0044] By installing a spring push rod 80214 and a knock pad 80215 inside the funnel 8022, when the screening net 8025 moves back and forth inside the funnel 8022, one end of the spring push rod 80214 will collide with the knock pad 80215, and the impact force generated by the impact will be transmitted to the inside of the bottom bin 8021 through the funnel 8022. Moreover, since the inner wall of the bottom bin 8021 is concave on both sides toward the center, the fertilizer that has been screened inside the bottom bin 8021 will move along the inclined inner wall under the action of the impact force, thereby assisting the fertilizer delivery pump 803 in fertilizer delivery.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
