Embodiment Construction
[0021] Such as Figure 1-3 As shown, a straw splitting machine described in the embodiment of the present invention mainly includes a frame 1 and a protective shell 2, the protective shell 2 is fixed on the frame 1, and a rotating shaft 3 is arranged inside the protective shell 2 , the rotating shaft 3 is fixed with a shifting plate 4, a moving knife 5 and a screw conveying device 6 in sequence from left to right; A discharge port 13 is provided at a position corresponding to the material shifting plate 4, and a fixed knife 11 is provided at a position corresponding to the movable knife 5 on the protective shell 2; the movable knife and the fixed knife are used together to grind straw raw materials. Among them, two fixed knives 11 are provided, and the two fixed knives 11 are symmetrically distributed on both sides of the protective shell 2 and corresponding to the moving knife 5. The right end of the rotating shaft 3 is fixed with a pulley, and the rotating shaft 3 is connect...

The invention discloses a straw devillicate machine. The machine mainly comprise a rack and a protective shell, wherein the protective shell is fixed to the rack, a rotary shaft is arranged in the protective shell, and a material poking plate, a movable cutter and a spiral conveying device are sequentially fixed on the rotary shaft from left to right; a material inlet is formed in the position, corresponding to the spiral conveying device, of the protective shell, a material outlet is formed in the position, corresponding to the material poking plate, of the protective shell, and a fixed cutter is arranged in the position, corresponding to the movable cutter, of the protective shell; the rotary shaft is driven through a motor. According to the machine, straw raw materials are transported to the position between the movable cutter and the fixed cutter through the spiral conveying device to be ground, and the straw raw materials are conveyed out by the material poking plate. The machine is simple in structure, convenient to maintain and low in price; due to the fact that gap between the movable cutter and the fixed cutter is adjustable, when the cutters are abraded, the cutters do not need to be replaced by only adjusting the gap between the two cutters; both the cross section of the cutting edge of the movable cutter and the cross section of the cutting edge of the fixed cutter are in the shape of sawteeth, the movable cutter and the fixed cutter are matched in a staggered mode, the contact area between the cutting edges is increased, work efficiency is improved, and meanwhile consumption of kinetic energy is reduced.
Description
technical field [0001] The invention relates to the field of machinery in the papermaking industry, in particular to a straw splitting machine. Background technique [0002] As a large agricultural country, our country produces about 600 million tons of crop straw every year, of which only 30% has been utilized, and the remaining 70% have been wasted as waste, and because of incineration, it has brought huge pollution to the environment every year . As an annual grass fiber, crop straw is a very good raw material for papermaking. If it can be fully utilized, it can not only increase the income of farmers, but also enrich the raw materials of papermaking enterprises, and reduce the harm to the environment caused by straw burning. At present, Most of the split raw materials for papermaking with straw fiber raw materials are processed by twin-screw refiners, extrusion tearing machines, etc. The twin-screw refiners and extrusion tearing machines mainly have the following disadv...
