Referring to fig. 1-2, a front counterweight assembly of a wheeled tractor comprises a front counterweight assembly 1 of the tractor, wherein the front counterweight assembly 1 comprises a mounting frame 101 mounted at the front end of the tractor, bearing rods 102 are mounted on two sides of the mounting frame 101, a counterweight block 6 is mounted between the bearing rods 102, a support frame 103 is mounted at one end, away from the mounting frame 101, of each bearing rod 102, the other end of each support frame 103 is mounted at the lower end of the mounting frame 101, and a damping device 5 for damping and buffering the counterweight block 6 is arranged on the mounting frame 101; in practical application, a triangular stable structure is formed by the mounting frame 101, the carrier bar 102 and the carrier bar 102, so that the overall strength is enhanced.

Further, the damping device 5 comprises a sleeve 501 in sliding connection with the mounting frame 101, the lower end of the support frame 103 is fixed on the outer wall of the sleeve 501, one end of the bearing rod 102 is fixed on the upper end of the sleeve 501, and the lower end of the sleeve 501 is provided with a damping spring 502; in practical application, when the tractor encounters a low-lying place, the counterweight 6 applies force to the sleeve 501 through the support frame 103 and the bearing rod 102, and the damping is performed through the damping spring 502 at the lower end of the sleeve 501.

Further, a sliding rod 3 is slidably connected inside the sleeve 501, and a buffer spring for buffering the impact force of the top of the support frame 103 is arranged at the upper end of the sliding rod 3; in practical application, when the front end of the tractor sinks suddenly, the load bearing rod 102 is prevented from directly impacting the upper end of the mounting frame 101 through the buffer spring, and the counterweight assembly is damaged due to sudden stress.

Further, the lower end of the counterweight block 6 is fixedly provided with anti-collision rubber; in practical application, through crashproof rubber can be better avoid 6 collisions of balancing weight to take place the abnormal sound.

Further, bearing blocks are fixedly arranged at two ends of the balancing weight 6, a plurality of groups of mounting grooves are formed in the outer wall of the bearing rod 102, a limiting plate 2 is slidably arranged on one side, located in the mounting grooves, of the bearing rod 102, and one end of the limiting plate 2 is mounted on the bearing rod 102 through a bolt; in practical application, through gliding limiting plate 2, convenient dismantlement and the installation to balancing weight 6.

Further, a protection plate 4 is fixedly arranged at one end of the bearing rod 102 far away from the mounting frame 101.

The working principle is as follows: before the tractor is used, the bolt at one end of the limiting plate 2 is unscrewed and taken out, then the limiting plate 2 is slid, the mounting groove at the upper end of the bearing rod 102 is leaked, then the number of the balancing weights 6 is increased or reduced and the positions of the balancing weights 6 are adjusted according to needs, after the adjustment is finished, the bolt is screwed after the limiting plate 2 is slid, so that the balancing weights 6 are fixed, the balancing weights 6 are adjusted according to actual requirements, unreasonable balancing weights are avoided, and the whole tractor is balanced;

further, when the front end of the tractor sinks suddenly, the counterweight block 6 and the bearing rod 102 are in a weightless state, so that the counterweight block can impact the upper end of the mounting frame 101, and the bearing rod 102 is prevented from directly impacting the upper end of the mounting frame 101 through the buffering of the buffer spring, so that the counterweight component is damaged due to sudden stress;

after the counterweight 6 is weightless, the counterweight 6 can drive the bearing rod 102 to move downwards, and the bearing rod 102 drives the sleeve 501 to slide downwards, so that the damping is performed through the damping spring 502 at the lower end of the sleeve 501, and the situation that the counterweight 6 suddenly bears the force on the front end of the tractor to cause the imbalance of the tractor and the danger of a driver is caused is avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
