Roller-type feeding and shredding device

Abstract

The invention discloses a roller-type feeding and shredding device. The roller-type feeding and shredding device includes a rack, a feeding mechanism and a shredding mechanism, wherein the feeding mechanism and the shredding mechanism are installed on the rack; a discharge hole of the feeding mechanism is aligned with a feeding hole of the shredding mechanism; the feeding mechanism comprises a lower pressing roller, an upper pressing roller, an upper pressing roller lower limit assembly, a tension spring and a swinging member, wherein the lower pressing roller and the upper pressing roller synchronously rotate in opposite directions, and the lower pressing roller is pivotally connected with the rack; one end of the swinging member is pivotally connected with the rack, the other end of theswinging member is pivotally connected with an upper pressing roller shaft, and the swinging member is supported on the upper pressing roller lower limit assembly together with the upper pressure roller; the upper end of the tension spring is connected with the end, close to the upper pressing roller shaft, of the swinging member, and the lower end of the tension spring is connected with the portion, located below the upper pressing roller lower limit assembly, of the upper pressing roller. The roller-type feeding and shredding device has the advantages of self-adaptive and adjustable materialfeeding gap, uniform and controllable shredding length, strong anti-winding performance, stable and reliable work and high work efficiency during operation.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a roller feeding and chopping device with self-adaptive adjustment of the feeding gap. Background technique [0002] After silage fermentation, the green feed is soft, juicy and palatable, and its nutritional content is higher than that of dry feed. It can increase and improve the feed intake of livestock and the digestibility of organic matter, and can be stored for a long time, so it has been widely used. [0003] At present, in the mechanized shredding process of silage (such as fibrous plant ramie), when harvesting different planting densities and different types of crops, if the structure of this part cannot be automatically adjusted according to the density of the crops, it will directly affect the operating quality of the harvester. , so that the material flow is not smooth, and even cause the blockage of the chopped feed. At the same time, the green feed i...

Problems solved by technology

[0003] At present, in the mechanized shredding process of silage (such as fibrous plant ramie), when harvesting different planting densities and different types of crops, if the structure of this part cannot be automatically adjusted according to the density of the crops, it will directly affect the operating quality of the harvester. , so that the material flow is not smooth, and even cause the blockage of the chopped feed

At the same time, the green feed is very easy to wrap around the machine, increasing the load on the machine, and there are problems such as reduced work efficiency and unstable work.
