DETAILED DESCRIPTION

[0023] Reference Figure 1-Figure 4 The adjustable wheel tractor frame includes a front channel steel 1, which is fixedly connected to a rear beam 3 by a plurality of third bolts 10. A plurality of strip holes are provided on the rear beam 3. A slide bar is fixed on the front beam 4, which moves in the strip holes. Triangular grooves are provided on both sides of the rear beam 3, and the front beam 4 is provided in the triangular groove. A limiting block is coaxially installed on the slide bar, and the bottom end of the limiting block is in contact with the top end of the rear beam 3. The front beam 4 is pushed and pulled to make the front beam 4 move in the triangular groove. When the front beam 4 moves to an appropriate position, the front beam 4 and the rear beam 3 are fixed by the first bolt 7.

[0024] The front channel steel 1 is in a "U" shape, and the third bolt 10 and the second bolt 8 are vertically arranged. The third bolt 10 and the second bolt 8 directly and fixedly connect the front channel steel 1 with the rear beam 3 and the top plate 15, thereby forming the main structure of the tractor frame.

[0025] The front channel steel 1 is provided with a clamping block 9 , which is clamped with the rear beam 3 , and the clamping block 9 further strengthens the fixing effect of the front channel steel 1 and the rear beam 3 .

[0026] The front channel steel 1 is fixedly connected to a top plate 15 via a plurality of second bolts 8 . A plurality of strip-shaped buffer holes are provided on the top of the top plate 15 . The strip-shaped buffer holes can alleviate the vibration of the tractor in the vertical direction.

The triangular grooves are provided with a plurality of shock-absorbing holes. The shock-absorbing holes are distributed in a rectangular array, which effectively prevents the vibration of components caused by the use of the tractor.

[0028] A support frame 11 is installed at the bottom end of the triangular rib 2. The support frame 11 is inclined, so that the tractor frame is triangular in shape as a whole, has better stability, and is generally suitable for various types of wheeled tractors.

[0029] The triangular ribs 2 are connected to each other via a plurality of balancing rods 12 , which support and fix the triangular ribs 2 and effectively prevent the triangular ribs 2 from vibrating significantly during the operation of the tractor.

[0030] The front beam 4 is fixedly connected with a rear connecting plate 5 , and a plurality of mounting holes are provided on the rear connecting plate 5 . The mounting holes can be structurally installed according to user requirements to maintain a balanced state of the rear connecting plate 5 and the front channel steel 1 .

[0032] The reinforcing structure 13 is triangular in shape, and the reinforcing structure 13 will make the connection between the triangular rib plate 2 and the supporting frame 11 more stable. At the same time, the rigid connection of the reinforcing structure 13 improves the shock absorbing effect of the triangular rib plate 2 and the supporting frame 11.

[0033] A plurality of circular holes are provided on the rear beam 3 and the front beam 4, and a first bolt 7 is provided in the circular hole. The first bolt 7 cooperates with a nut to fix the rear beam 3 and the front beam 4. By rotating the first bolt 7, the first bolt 7 is detached from the rear beam 3 and the front beam 4. At this time, the distance between the rear beam 3 and the front beam 4 can be adjusted, and the front beam 4 can be removed from the rear beam 3.

[0034] The fourth bolt 14 is located at one end of the carrier 11, and the triangular rib plate 2 is connected to the other end of the carrier 11 through the fifth bolt 16. The carrier 11 is fixedly mounted with the reinforcement structure 13 through a plurality of fourth bolts 14. The fourth bolt 14 is rotated to disconnect the reinforcement structure 13 from the carrier 11, and the reinforcement structure 13 can be manually removed from the carrier 11. After the fourth bolt 14 is separated from the reinforcement structure 13 and the carrier 11, the fifth bolt 16 is continued to be rotated to disconnect the carrier 11 from the triangular rib plate 2. At this time, both ends of the carrier 11 are disconnected from the tractor frame body, and the removal of the carrier 11 is completed.
