Bale busting and crushing machine

Abstract

The invention aims to provide a bale busting and crushing machine. The bale busting and crushing machine is characterized in that the feeding of a feeding conveyor (1) is in a horizontal direction, and the external dimensions of an outlet of the feeding conveyor (1) are the same as those of inlets of crushers; rotors of each crusher are an upper layer rotor and a lower layer rotor; the two crushers are connected in series; and a central axis of each upper layer rotor (3) of each crusher and the central axis of the corresponding lower layer rotor (3) are in the horizontal direction, and a displacement distance towards the inlets is 100-400 millimeter. When the bale busting and crushing machine is used, forage at the upper part of the sheet-form forage cannot suddenly and intensively fall down during bale busting between two bales, so that current fluctuation and mechanical breakdown of a motor cannot be generated, and the problems of being uneven in length, large in dust, inconvenient to repair and maintain and the like can also be solved.

Description

technical field [0001] The patent of the present invention relates to a straw bale unbundling grinder, which is usually used in environmental protection, fertilizer, papermaking, biogas, feed, chemical, power generation and other industries where grass and straw need to be unbundled and pulverized. Background technique [0002] Usually this kind of bale unbundling grinder is mainly composed of a feed conveyor (1), a grinder (2), and a discharge conveyor (3). The grinder (2) is composed of a rotor (4), a blade ( 5), the motor (9), and the shredder shell (11). When working, the bale enters the shredder (2) from the feed conveyor (1), and the motor (9) drives the rotor (4), and the rotor (4 ) The upper blade (5) rotates to untie and crush the bale sent by the feeding conveyor (1), and the unbundled loose grass is discharged by the discharge conveyor (3). Due to the high height of the bale, it is difficult to crush The machine (2) usually uses the upper and lower rotors (4) to ...

AI Technical Summary

Problems solved by technology

The manufacture of straw bales is to go through the filling of the grass box, then compress, press into flakes, and then push forward. After many cycles, the flakes of grass are arranged into long bundles. Inside the flakes, the fibers are connected to each other. It is strong, and the pieces are relatively loose and easy to separate. Therefore, when an ordinary unbaler is unbundling, when it is between two bales, the upper part of the sheet material will suddenly separate and fall together. It causes the motor current to fluctuate and cause equipment failure, which is why it is difficult to popularize the unbundling machine at present.

[0005] 2. The output of the bale unbundling grinder and the fineness and length of the grass after unbundling have a great influence

If multiple pulverizers are connected in series, but the back pulverizer has a large amount of material, the length of the grass will be hit by an unstable number of times, and the length of the grass coming out will be different, and the uniformity will be poor.

[0006] 3. The shredder (2) has a series structure, the replacement of internal blades, and difficulties in equipment installation, repair and maintenance.

[0007] 4. When the bale unbundling shredder is working, the dust at the outlet is large, which does not meet the environmental protection requirements.
