Abstract

The invention belongs to stockbreeding machining, and in particular relates to a hydraulic pasture and straw cutting device comprising a rack part (6), wherein the center of the cutting device is provided with a rotating mechanism (8), the rotating mechanism (8) is respectively and fixedly connected with a first feeding box (41), a second feeding box (42), a third feeding box (43) and a fourth feeding box (44) which are uniformly distributed along the circumference and are respectively provided with a square hole (40) at the bottom; a first top plate (91) and a second top plate (92) are arranged above two of the first feeding box (41), the second feeding box (42), the third feeding box (43) and the fourth feeding box (44); a first pressing-down hydraulic cylinder (51) and a second pressing-down hydraulic cylinder (52) are respectively fixed on the first top plate (91) and the second top plate (92); and a first blade-shaped cutter grid (71) and a second blade-shaped cutter grid (72) are arranged below the first top plate (91) and the second top plate (92) and are respectively connected with the first pressing-down hydraulic cylinder (51) and the second pressing-down hydraulic cylinder (52).

Description

technical field [0001] The invention belongs to the technical field of animal husbandry machinery processing, and in particular relates to a hydraulic pasture and straw cutting device. Background technique [0002] Straw is the most important by-product of agricultural crops in rural areas. Chinese farmers have a tradition of using straw as forage to feed livestock since ancient times. At present, the annual output of various crop straws in my country is about 700 million tons. This is a very considerable forage resource under the current situation of food shortage in our country and the phenomenon of competition between humans and animals for food. [0003] In my country's vast agricultural production areas, in addition to producing more than 400 million tons of grain, more than 600 million tons of straw are also produced each year. Straw is the most important by-product of agricultural crops in rural areas. Straw processing machinery is used to process straw and become f...

Problems solved by technology

At present, there are mainly two types of chaff cutters, the rotary cutter type and the hob cutter type, which are generally inconvenient to operate, complicated in structure, high in cost, affect the performance of the machine, and reduce the actual productivity.

More importantly, the literature shows that the disc cutter and hob cutters have disadvantages such as low chopping efficiency and high energy consumption. Excessive energy consumption is in the rotation of the cutter and overcoming the friction of the cutter operation.
