This structure enables the double-headed telescopic rod 5 to be relatively stable relative to the transmission box 3 under the positioning of the positioning tube 4. When the double-headed telescopic rod 5 is started, the positioning seat 12 can be pushed to move to both sides through the connecting head 501, and the two ends of the double-headed telescopic rod 5 are respectively connected with the connecting heads 501, and the two ends of the double-headed telescopic rod 5 are fixed with the positioning seat 12 through the connecting head 501, and the positioning seat 12 is penetrated and matched with the driving rod 9. The same side of the driving wheel 8 and the driven wheel 13 are both clamped with a scraper 10, and the scraper 10 is movably penetrated and matched with the driving rod 9. The scraper 10 on the side of the driving wheel 8 and the roller stabilizing frame 7 are both screwed and fixed with the positioning seat 12, and the roller stabilizing frame 7 on the side of the driving wheel 8 is movably penetrated with the mounting rod 6, and the side of the driven wheel 13 is The scraper blade 10 on the surface is screwed and fixed with the roller fixing frame 7, and the roller fixing frame 7 on the side of the driven wheel 13 is fastened with the rear latch through the mounting rod 6. This structure enables the driving wheel 8 and the driven wheel 13 to be used for scraping mud through the scraper blade 10. The driving wheel 8 can be adjusted in spacing, while the spacing of the driven wheel 13 is not adjustable, so that the bottom of the four-wheeled mini-agricultural machine 1 is firmly supported. The scraper blade 10 is tilted at the bottom, and scraping teeth 1001 are evenly spaced at the bottom of the scraper blade 10, and the scraping teeth 1001 are matched with the driving wheel 8 and the driven wheel 13. This structure enables the scraper blade 10 to scrape the mud attached to the surface of the driving wheel 8 and the driven wheel 13 through the scraping teeth 1001, and avoid affecting the rotation of the driving wheel 8 and the driven wheel 13. In order to remove the dirt on the surface of the driving wheel 8 and the driven wheel 13, the four-wheeled mini-agricultural machine 1 is prevented from being uneven, thereby improving the stability of the four-wheeled mini-agricultural machine 1. The side of the driving rod 9 is evenly spaced with limiting convex strips 901 of an integrated structure, and the limiting convex strips 901 are inserted into the transmission rod 11.

[0018] Working principle: When using the device to prevent the lateral tilting and tipping of the four-wheeled mini-agricultural machinery in hilly and mountainous areas, first, when the four-wheeled mini-agricultural machinery 1 is working in the hilly area, the frame 2 drives the driving wheel 8 to rotate through the transmission structure installed in the transmission box 3 to realize the movement of the frame 2, and the driven wheel 13 assists the movement of the four-wheeled mini-agricultural machinery 1. The driven wheel 13 is fixed to the mounting rod 6 through the roller stabilizing frame 7 to keep the spacing of the driven wheels 13 consistent, and the driving wheel 8 improves the support stability by increasing the spacing. The driven wheel 13 and the driving wheel 8 constitute a stable support treatment for the frame 2, and the four-wheeled mini-agricultural machinery 1 is provided with a protective treatment to prevent lateral tilting and tipping. When adjusting the spacing of the driving wheel 8, the double-headed telescopic rod 5 is stabilized relative to the transmission box 3 through the positioning tube 4, and the double-headed telescopic rod 5 is connected to the connecting head. 501 is connected with the positioning seat 12, and the positioning seat 12 is driven to move. The limiting collar 902 makes the driving rod 9 stable relative to the positioning seat 12, so that the positioning seat 12 can drive the driving rod 9 to move. When the driving rod 9 moves, it is movably limited relative to the transmission rod 11 through the limiting convex strip 901, and the transmission rod 11 always drives the driving rod 9 to rotate through the transmission mechanism to realize the rolling of the driving wheel 8. At the same time, when encountering mud in the hilly area, the scraper blade 10 is positioned by the positioning seat 12 and is relatively stable relative to the driving wheel 8 and the driven wheel 13, so that the driving wheel 8 and the driven wheel 13 can scrape the mud through the scraping teeth 1001 to prevent the mud from sticking to the wheels and affecting the stability of movement, thereby ensuring the safe use of the four-wheeled micro-agricultural machinery 1 in the hilly and mountainous areas, thereby completing a series of tasks.
