Description

Bale breaking crusher

Technical Field

The invention relates to a bale breaking crusher, which is generally used for occasions needing bale breaking, such as grass, straws and the like in the industries of environmental protection, fertilizer, paper making, methane, feed, chemical engineering, power generation and the like.

Background

Usually this kind of bale breaking rubbing crusher, mainly by feeding conveyer (1), rubbing crusher (2), the conveyer (3) of discharging constitutes, rubbing crusher (2) wherein by rotor (4), blade (5), motor (9), rubbing crusher shell (11) are constituteed, in operation, the bale is followed and is got into rubbing crusher (2) by feeding conveyer (1), motor (9) drive rotor (4), blade (5) are rotatory on rotor (4), untie and smash the bale that feeding conveyer (1) sent into, loose grass after the bale breaking is discharged by conveyer (3) of discharging, because the bale height is high, rubbing crusher (2) usually adopt two upper and lower rotors (4) to smash simultaneously.

Such a pulverizer has the following problems:

1. the fluctuation of the operating current is large. To solve this problem, the structural features of rectangular parallelepiped bales are first known. The manufacture of the bale is that the charging of the grass box is carried out, the compression is carried out, the bale is pressed into a sheet shape and then is pushed forwards, after a plurality of cycles, the sheet-shaped grass is arranged into a long bale, fibers are mutually connected and are firmer in the sheet shape, and the sheets are relatively looser and easy to separate.

2. The influence of the yield of the bale breaking crusher and the fineness and the length of the grass after bale breaking is large. The grass discharged when the yield is high is long, and the grass discharged when the yield is low is short, so that the method is not suitable for production. The production requirement is that the length remains essentially constant as the yield increases. The crushers (2) are not connected in series. If a plurality of crushers are connected in series, but the feed back of the rear crusher is large, the hitting times of the length of the grass are unstable, the length of the discharged grass is different, and the uniformity is poor.

3. The crushing machine (2) is in a series structure, the internal blades are replaced, and the equipment is difficult to install, maintain and maintain.

4. The bale breaking crusher has large dust at the outlet during working, and does not meet the requirement of environmental protection.

For a long time, the problem is a key problem which troubles the technical improvement of the bale breaking crusher.

Disclosure of Invention

The invention aims to provide a bale unbinding crusher, which is required to prevent forage on the upper part of sheet forage from suddenly falling down in a concentrated manner between two bales and causing current fluctuation of a motor when the bale unbinding crusher is unbiased; the application aims to eliminate the defects of the serial structure of the pulverizer, so that the unstable phenomenon of the grass length is eliminated, and the uniformity is improved; meanwhile, the problem that the series structure of the crusher is inconvenient to maintain is solved, the internal blade can be replaced, the equipment is convenient to maintain, and the problem that discharged dust is large is solved.

The invention relates to a grass bale breaking crusher, which is redesigned and has the following structure:

a bale breaking crusher mainly comprises a feeding conveyor (1), a crusher (2) and a discharging conveyor (3), wherein the crusher (2) comprises rotors (4), blades (5), a motor (9) and a crusher shell (11), and is characterized in that the feeding conveyor (1) feeds materials in a horizontal direction, the outlet overall dimension of the crusher is the same as the inlet of the crusher, the crusher rotors comprise an upper rotor and a lower rotor, the two crushers are installed in series, the central axis of the upper rotor (3) of the crusher and the central axis of the lower rotor (3) of the crusher are displaced to an inlet by a distance A, A =100 mm to 400 mm, and when the bale breaking crusher works, the feeding conveyor conveys the materials to the inlet

The bale that machine (1) was sent into, the upper strata of flaky grass receive the decomposition and the smashing of blade (5) of upper rotor (4) at first, like this, when lower floor's grass met lower floor rotor (4), the material on upper strata had not had, had avoided between two bales, the forage on flaky material upper portion can concentrate the problem that falls suddenly, also eliminated motor current fluctuation and equipment trouble simultaneously. The rotor (4) of the second crusher (2) adopts variable speed, if the yield is increased, the feeding conveyor (1) is accelerated, the finished fiber can be increased, and the second crusher is accelerated through a rotor speed changer, so that the crushing times of the blades are increased to adjust the length of the finished fiber, and when the yield is increased, the length of the finished fiber is basically unchanged. At the front end of first rubbing crusher lower floor rotor (4), the design has hinders material ring (6), hinder material ring (6) and become circular arc's slice, one end is connected with rubbing crusher (2) lower plate, one end is connected with hindering flitch (7) extension plate, the installation of being separated by between every piece, stagger with the blade, blade (5) length exceedes to hinder material ring (6) distance and is C, C =5 to 50 millimeters between, just so limited the thickness of the material of the blade cutting of lower part rotor, the problem of the lower floor material concentrated entering suddenly has been solved. On the upper portion of first rubbing crusher upper rotor (4), limit material dead knife (14) that can adjust have been designed, there is waist shape slot hole in the middle of dead knife (14), be connected with knife rest (15) through adjusting bolt (16), loosen adjusting bolt (16), can adjust the distance of dead knife (14) and rotor (4), the quantity of dead knife (14) corresponds the same with hindering material ring (6), can make the length of the ejection of compact of upper rotor and the ejection of compact of lower part rotor more even. A material blocking plate (7) is arranged between the two crushers, the width b, b = 100-. A cloth bag filter (12) is arranged above a discharge port of the pulverizer (2), and an outlet of the cloth bag filter is connected with a fan (13) so that dust at the discharge port is eliminated. The blade (5) of rubbing crusher designs into the slice, and one end has the installation pinhole, and another work end has the wear-resisting material of stereoplasm, and the then face of work end is the forked type, and the branching quantity is more than two forks, and the branching can be straight and crooked various changes for bale breaking becomes the separation of massing, avoids thin crushing, avoids hammer leaf temperature to rise rapidly. The roller wheels are arranged below the feeding conveyor (1), the rail (10) is arranged below the feeding conveyor, and when the hammer sheets are maintained and replaced, the roller wheels can be moved along the rail, so that the feeding conveyor is convenient to work.
