Description

Technical Field

[0001] The utility model relates to the technical field of silage filling machines, in particular to a silage filling machine silo receiving and locking mechanism. Background Art

[0002] Bagged silage refers to squeezing and filling chopped silage raw materials into special fermentation bags through special equipment, and after a certain period of time, making silage feed and storing it for a long time. The working principle of the existing silage filling machine is as follows: The silage filling machine is towed by a tractor. 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 filling pressure during the continuous filling of the silage material, it is necessary to control the pulling force of the steel wire rope. The manual control accuracy is low. When the filling 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, and the moving speed of the filling machine is adjusted 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 several 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 connected; a feeding roller is provided on the feeding side of the connecting part, and a comb-shaped plate is provided on the discharging side.
