[0035] In the construction practice of an all-terrain vehicle that is convenient for material transportation:

[0036] 1. When the loading assembly does not need to be expanded, the left front cover 14, the left rear cover 11, the right front cover 13, and the right rear cover 12 are rotated open by the hinge 30, and the transported items are placed in the space formed by the left front box 16, the left rear box 5, the right front box 15, and the right rear box 20. When the loading assembly needs to be expanded, the second electric telescopic rod 17 on the rear end surface of the inner wall of the left rear box 5 and the front end surface of the inner wall of the left front box 16 is activated to push the left front box 16 forward, because the first left front extension plate 18 is slidably connected to the inside of the left rear box 5, and the length of the second electric telescopic rod 17 is shorter than that of the left rear box 5, the left front box 16, The sum of the lengths of the first left front extension plate 18 prevents all left front boxes 16 from falling out. The left front box 16 moves forward through the second left front extension plate 19 on the right side to drive the right front box 15 to move forward. Similarly, because of the right front extension plate 27, the right front box 15 will not fall out. By setting another second electric telescopic rod 17 on the lower middle side of the left end surface of the inner wall of the left front box 16 and the lower middle side of the right end surface of the inner wall of the right front box 15, the right front box 15 can be pushed out to the right, because the second left front extension plate 19 is slidably connected to the inside of the right front box 15, and the length of the second electric telescopic rod 17 is smaller than that of the left front box 16, the second left front extension plate 19, The sum of the lengths of the right front box 15, so the right front box 15 will not fall out, the right front box 15 drives the right front extension plate 27 to move rightward, the middle plate 41 falls out from the inside of the right front extension plate 27, the right front box 15 and the right end surface of the right rear box 20 are fixedly connected with the left front cover 14 and the right front cover 13 through the hinge 30, when the right front box 15 moves forward, the right front extension cover 25 slides out from the right rear cover 12, the right front cover 13 drives the second left front extension cover 26 inside to move forward, the second left front extension cover 26 drives the left front cover 14 and the first left front extension cover 22 to move forward, and the second left front extension cover 26 falls out from the left rear cover 11, Then pull the left front cover 14 and the left rear cover 11 to the left, remove the left rear extension cover 23 from the right rear cover 12, remove the middle cover 24 from the first left front extension cover 22, and remove the second left front extension cover 26 from the right front cover 13, and then fix the left front cover 14 and the left rear cover 11 to the left end surface of the left front box 16 and the left rear box 5 through the screw seat 4 on the lower end surface of the left front cover 14 and the left rear cover 11, so as to achieve the expansion and contraction of the left front box 16, the left rear box 5, the right front box 15, and the right rear box 20, and the left rear box 5, the left rear extension plate 21, the right rear box 20, the right front extension plate 27, the right front box 15, and the left front second extension plate. The left front box 16 and the left front second extension plate are connected to each other, and the left front cover 14, the left front first extension cover, and the left rear cover 11. The left rear first extension cover, the right rear cover 12, the right front extension cover 25, and the left front second extension cover are connected to each other in pairs. Through the above arrangement, the loading assembly can achieve a capacity expansion of 2.25 times.

[0037] 2. After the items are loaded, align the left limiting strip 28 and the right limiting strip 29 on the lower end faces of the left rear box 5 and the right rear box 20 with the left first limiting groove 9, the left second limiting groove 8, the right first limiting groove 43, and the right second limiting groove 44 on the support plate 1 and the load-bearing plate 6, and slide inside them. When sliding to the moving bin 33, start the motor 36 to drive the bidirectional threaded rod 37 inside the threaded rod bin 42 to rotate, and the bidirectional threaded rod 37 drives the left moving block 38 and the right moving block 39 to move to the middle of the bidirectional threaded rod 37, and the left moving block 38 and the right moving block 39 drive the left limiting rod 31 and the right limiting rod 40 to slide in the sliding groove 32, and the left limiting rod 31 and the right limiting rod 40 slide to the middle of the moving bin 33, and align the left through hole 45 and the right through hole 46 inside the left limiting strip 28 and the right limiting strip 29 with the left limiting rod 31 and the right limiting rod 40. The limiting rod 40 continues to slide, and the left limiting strip 28 and the right limiting strip 29 are fixed on the left limiting rod 31 and the right limiting rod 40. At this time, starting the motor 36 can realize the flexible expansion of the loading assembly on the support plate 1 and the bearing plate 6. The waterproof box 10 with the left limiting strip 28 and the right limiting strip 29 on the lower end face can also be fixed on the left limiting rod 31 and the right limiting rod 40 through the above operation. At this time, do not start the motor 36. The motor 36 only assists in expanding the loading assembly. After loading is completed, the device can be transported by the push handle 3 and the driving wheel assembly 2. In case of severe rainy weather and deep water on the road, the first electric telescopic rod 7 fixed inside the telescopic rod protective shell 34 on the outer side of the lower end face of the support plate 1 can be started to lift the limiting blocks 35 at the four corners of the bearing plate 6 upwards. In conjunction with the waterproof box 10, the risk of water damage to agricultural products can be greatly reduced.
