Description

Technical Field

[0001] The utility model relates to the technical field of silage filling machines, in particular to a wheel reversing and lifting device for a silage filling machine. Background Technique

[0002] Bagged silage means that chopped silage raw materials are extruded and filled into a special fermentation bag through special equipment, and after a certain period of time, silage feed is made and stored for a long time. The working principle of the existing silage filling machine is as follows: the silage filling machine is dragged by a tractor, and at the same time, the tractor also provides power for the feeding mechanism of the silage machine; the auger of the feeding mechanism rotates, and the raw materials are conveyed from the feeding port towards the fermentation bag. The extrusion pressure received by the silage raw materials gradually increases during the process of being input from the feeding port towards the fermentation bag, and the density gradually increases; at the same time, as the high-density silage material increases, the pressure of the silage material in the fermentation bag increases, and the reaction force pushes the silage filling machine and the tractor forward. At the same time, the mouth-opening shovel releases the fermentation bag, and the high-density silage material continues to be filled, and this continuous operation is carried out until a fermentation bag is filled. After the filling is completed, the tractor pulls the filling machine and removes the fermentation bag, and closes the door to complete the filling of a bag of silage feed.

[0003] Since the feeding mechanism does not change the material density, the silage compaction mainly relies on the pulling force of the steel wire rope. To ensure the stability of the perfusion pressure during the continuous filling of the silage material, it is necessary to control the pulling force of the steel wire rope. The accuracy of manual control is low. When the perfusion pressure increases to a certain value, the steel wire rope will be broken, resulting in danger.

[0004] A patent with a publication number of CN113942688B is disclosed in the prior art. During the filling of this solution, the braking mechanism is controlled according to the stretching rate of the silage bag to adjust the moving speed of the filling machine, so as to control the filling pressure of the silage bag. The self-propelled silage filling machine includes a self-propelled mechanism, a braking mechanism and a filling mechanism; the self-propelled mechanism includes a frame, and a plurality of wheels are provided on the frame; the braking mechanism is used to brake the wheels; the filling mechanism includes a feeding bin and a pressure filling bin, and the lower parts of the feeding bin and the pressure filling bin are communicated; a feeding roller is provided on the feeding side of the communicating part, and a comb-shaped plate is provided on the discharging side.

[0005] The existing devices including the above-mentioned patent gradually expose the deficiencies of the prior art during use, which are mainly manifested in the following aspects:

[0006] Since the weight of the silage filling machine is dozens of tons, when the existing silage filling machine reverses the wheels, it is necessary to use an external machine for traction and reversing, and the operation is very cumbersome and laborious, which affects the reversing efficiency of the wheels.

[0007] To sum up, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model
