[0063] like Fig.12 As shown, according to this embodiment, preferably, the track shoe 701 of the track 7 is made of metal and has high strength and wear resistance to withstand the weight of the vehicle and various pressures and frictions during driving.

[0064] Preferably, the crawler track 7 adopts a large-size, wide crawler track design to enhance ground adhesion and reduce soil compaction, which is particularly suitable for the soft soil environment for broccoli cultivation.

[0065] The design of the track shoe 701 is conducive to driving on various complex terrains, such as mud, sand, snow, etc. This is because the contact area between the track 7 and the ground is large, which can evenly distribute the weight of the vehicle and reduce the pressure per unit area, thereby preventing the vehicle from sinking into soft ground. The track shoe 701 is a long strip-shaped raised edge, and the two ends of the adjacent track shoe 701 are staggered in length and short, which can increase the friction between the track and the ground, provide better grip, and make the vehicle more stable when driving on various terrains, not easy to slip, and can better adapt to broccoli planting fields of different terrains, whether it is hilly, mountainous or low-lying areas, can improve the stability and passability of the chassis, reduce the bumps and damage of the machine caused by the undulating terrain, and improve the working efficiency. Because the friction between the track 7 and the ground is large, it can provide strong traction, so that the vehicle can easily climb steep slopes, cross obstacles, etc. The tracked vehicle has good stability during driving, is not easy to roll over or slip, and can adapt to walking in a straight line, which is very important for adapting to broccoli fields. The invention has strong adaptability and is easy to operate. It is more practical for the current situation of scattered planting by individual farmers in China and does not require additional transportation vehicles.

[0066] The chassis bracket welding plate 6 of the present invention is made of new composite materials such as high-strength alloy steel or carbon fiber. Under the premise of ensuring the overall strength and rigidity of the chassis, the weight of the chassis is reduced, the fatigue resistance and corrosion resistance of the material are improved, the service life of the chassis is extended, and the maintenance cost is reduced.
