Embodiment Construction

[0059] Such as figure 1 As shown, the straw cutting machine includes a frame 11 with a movable conveyor belt 12 on the frame 11 , and the cutting mechanism of the straw cutting machine is arranged on the frame 11 and close to the conveyor belt 12 .

[0060] The cutting mechanism of the straw cutting machine includes a knife rest 3, a cutter 1, a pretensioner 7 and a driving member 13. There is a guide structure between the knife rest 3 and the frame 11, and the guide structure can make the knife rest 3 relative to the frame. 11 Pan up and down.

[0061] The cutter 1 is fixedly connected to the knife holder 3, the pretensioning part is connected to the knife holder 3 and after the pretensioning part is in contact with the straw material, the pretensioning part can move up, so that the pretensioning part moves from the lower part of the cutter 1 to the Cutter 1 is flush with each other.

[0062] There is a transmission mechanism one between the driver 13 and the conveyor belt ...

Abstract

The invention provides a cutting mechanism of a straw cutting machine and belongs to the technical field of machines. The problem that an existing straw cutting machine is complex in structure is solved. According to the cutting mechanism of the straw cutting machine, a movable conveying belt is arranged on a machine frame of the cutting machine, the cutting mechanism is arranged on the machine frame and located on the upper portion of the conveying belt and comprises a knife rest, a cutting knife, a pretensioning piece and a driving piece, a guide structure enabling the knife rest to horizontally move up and down relative to the machine frame is arranged between the knife rest and the machine frame, the cutting knife is fixedly connected to the knife rest, the pretensioning piece is connected to the knife rest and can move from the lower portion of the cutting knife to be flush with the cutting knife after making contact with straw materials, a first driving mechanism is arranged between the driving piece and the conveying belt and can drive the conveying belt to move, and a second driving mechanism is arranged between the driving piece and the cutting knife and can drive the cutting knife to move relative to the machine frame. The cutting mechanism of the straw cutting machine is compact in structure.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a straw cutting machine for cutting straws, in particular to a cutting mechanism of the straw cutting machine. Background technique [0002] Straw cutting and crushing are the primary steps in the manufacture of biomass energy products. my country is rich in biomass resources such as crop stalks and agricultural product processing residues, with 700 million tons of crop stalks alone each year. The annual production of crop straw in Zhejiang Province is about 9.6 million tons, equivalent to 4.8 million tons of standard coal. [0003] Biomass energy such as straw and firewood used to be the main living fuel in rural areas. In recent years, with the continuous development of agricultural production and rural economy, the proportion of high-grade commercial energy in rural living energy has increased, and the proportion of straw has gradually decreased. [0004] Crop straw has a la...
