[0027] The specific design of the aforementioned key components will be discussed in detail below:

[0028] The traveling mechanism also includes a fixed frame 4 and a chassis 9. The fixed frame 4 is located at the rear of the base frame 2. The rear wheel 5 is mounted on the fixed frame 4 via an axle. A fixing rod 6 is provided on the outer side of the axle and connected to the fixed frame 4. The chassis 9 is fixedly mounted on the inclined platform via a connector. The front wheel 11 is located at the bottom end of the chassis 9. The rear wheel 5 is mounted between the side plates of the fixed frame 4 via a through axle. To enhance rigidity, two inclined fixing rods 6 are symmetrically welded on the outer side of the axle, with their ends firmly connected to the axle and the middle crossbeam of the fixed frame 4, respectively, forming a stable triangular support. The front wheel 11 is mounted on the fork at the bottom end of the chassis 9.

[0029] The connector is a wing bolt 10, and a spring washer is provided between the wing bolt 10 and the frame 9. The frame 9 is fastened to the inclined platform by the wing bolt 10 as a connector. To further prevent loosening during vibration, a spring washer is installed between the nut of the wing bolt 10 and the frame 9.

[0030] The rear wheel 5 and the front wheel 11 are provided with soil-embracing teeth on their outer circumferential surfaces. These soil-embracing teeth are preferably integrally molded with the tire using wear-resistant rubber, and are in the form of regular blocks or teeth, evenly distributed along the tire's circumference, and can be staggered along the axial direction. The soil-embracing teeth have a specific angle and depth to effectively embed themselves into loose soil or turf. When operating on slopes or slippery surfaces, traditional smooth tires are prone to slipping and spinning. The soil-embracing teeth, through mechanical embedding into the ground, provide a gripping force higher than friction.

[0031] The fertilizer outlet pipe 17 includes a connected metal rigid pipe section and a silicone flexible hose section, with a manual valve 18 installed on the metal rigid pipe section. The upper section of the fertilizer outlet pipe 17 is a metal rigid pipe connected to the bottom outlet of the fertilizer storage box 12, and the lower section is a silicone flexible hose sleeved at the end of the rigid pipe. The manual valve 18 for controlling the flow rate is installed on the metal rigid pipe section. The outlet of the fertilizer outlet pipe 17 faces the soil-digging mechanism. During operation, the outlet of the silicone hose is adjusted and fixed to face directly towards the soil-digging teeth 3. Under the action of gravity, the fertilizer flows backward along the fertilizer outlet pipe 17 and into the groove dug by the soil-digging teeth 3.

[0032] The system also includes an electronic control system, comprising a battery 20 and a toggle switch 15. The toggle switch 15 is located at the rear of the mixing motor 14, and the battery 20 is located at the bottom of the fertilizer storage box 12. The battery 20 is installed in a dedicated tray at the bottom of the fertilizer storage box 12, lowering the overall center of gravity. The control component is a waterproof toggle switch 15, located on the electrical control box behind the mixing motor 14, easily accessible by the operator's fingers, directly controlling the start and stop of the mixing motor 14. The front wheel 11 is a power wheel with an integrated hub motor. The hub motor is electrically connected to the battery 20 to drive the front wheel 11 to assist in climbing. A power assist control switch is provided on the push handle 7 to adjust the start and stop of the hub motor. A push handle 8 is provided at the end of the push handle 7 for easy gripping by the operator. The push handle 8 is preferably a rotatable handle serving as a hub motor power adjustment switch.

[0033] The bottom of the mixing motor 14 is fixedly connected to the main frame 1 via a connecting seat, and supports 19 are provided on both sides of the mixing motor 14 to connect to the rear end of the vehicle body. To ensure the stable operation of the mixing motor 14, a double fixing method is adopted. The bottom of the mixing motor 14 is rigidly connected to the main frame 1 via bolts through the connecting seat; supports 19 are symmetrically arranged on both sides of the housing of the mixing motor 14, and the supports 19 are connected to the rear end of the vehicle frame 9, effectively suppressing the radial vibration of the mixing motor 14 during operation.

[0034] The soil-scraping mechanism consists of soil-scraping teeth 3 located on the front side of the base frame 2. A lid 13 is provided on the top of the fertilizer storage box 12. The soil-scraping mechanism is composed of sharp, wedge-shaped soil-scraping teeth 3.
