The roller-cutter type straw pulverizer comprises a feed hopper, a pulverizing chamber, a roller cutter and a discharging port. The feed hopper is connected on the pulverizing chamber. The discharging port is connected with a lower shell of the pulverizing chamber. The pulverizing chamber is in a transverse cylinder shape and the roller cutter is axially arranged inside the cylinder of the pulverizing chamber. The roller cutter comprises a roller, cutter holders and pulverizing blades. The cutter holders are arranged on the roller at intervals. Each cutter holder is provided with more than one pulverizing blade. The pulverizing blades can be used for cutting by operating with fixing blades fixed on the inner wall of the pulverizing chamber. The shell under the axis of the pulverizing chamber is an arc-face sieve plate. The roller-cutter type straw pulverizer is reasonable in design, simple in operation, and safe and high in efficiency; and stalk materials can be cut and pulverizd into same sizes, natural sources are fully utilized while working efficiency is improved, farmers can work conveniently in the field, and the roller-cutter type straw pulverizer is suitable for promotion and application.

Description

technical field [0001] The invention belongs to cutting equipment for cutting hay, stalks or the like, in particular to a roller-knife plant straw grinder. Background technique [0002] With the continuous development of agricultural technology, crop production and income have been increased, which has brought good benefits to farmers. Some crops will leave straw after the crops mature and pick the fruit, such as: rice, corn, etc. The straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and the straw is also Can be fodder for some animals. However, the disposal of these straws has troubled most farmers. Some farmers choose to burn straws in the field. This behavior not only wastes resources, but also easily causes unnecessary fires.

Problems solved by technology

However, the disposal of these straws has troubled most farmers. Some farmers choose to burn straws in the field. This behavior not only wastes resources, but also easily causes unnecessary fires.

Most farmers use a straw grinder to process straw. The straw grinder can crush corn stalks, straw, peanut skins, bean stalks, and other combustible crop waste stalks. The crushed straw can be used as daily fuel or feed livestock, so that It avoids the waste burning of these crop straws, protects the environment well, and effectively develops renewable energy, but its work efficiency is low, and the moisture content of straws is relatively strict

The patent No. is 2012200434967, and the public document titled Hammer Knife Straw Crusher solves the above problems, but it cannot control the size of the crushed straw, and the crushed straw is ejected through the discharge port of the machine, and some of them are too large and need to be crushed. Rework, straw scraps that are not of the same standard will cause inconvenience to users in use

In addition, the device is cumbersome to process and manufacture, and the cost is high, which is unfavorable for large-scale promotion
