Abstract

The utility model provides a bag breaking and crushing device for the life garbage, which comprises a box, a feed hopper, a baffle plate, a discharge port, rollers and a power device, wherein, the rollers are installed in the box and rotate in opposite direction. The feed hopper is positioned above the box, and the baffle plate is fixed in inclination on the inner wall of the upper end of the box. The rollers are driven by a power unit to operate, and a plurality of serrated knives are evenly arranged on the rollers. The bag breaking and crushing device for life garbage is characterized in that the two rollers are driven by the power unit to operate in different speeds, and the axial lines of the rollers are parallel. The rotary directions of the plurality of serrated knives on the two rollers are same. A plurality of serrated knives and the axial lines of the rollers form certain included angles to form shearing. The two rollers which are provided with serrated knives operate in different speeds under driving of the power unit. Under the action of the baffle plate, the garbage infunded from the feed hopper intensively falls into the shearing work cavity of the two rollers, and the serrated knives which rotate in opposite direction carry out bag breaking and crushing to the garbage, guaranteeing that the crushing is thorough and the garbage can not leak from the net. The crushed garbage is expelled from the discharge port which is beneath the rollers. The bag breaking and crushing device for life garbage has the advantages of simple structure, low cost, high work efficiency, low noise and safety.

Description

House refuse broken bag reducing mechanism

Affiliated technical field

The utility model provides a kind of house refuse broken bag reducing mechanism, belongs to the destroy technology field of solid waste.

Background technology

Domestic waste is more and more now, and severe contamination environment, brings serious harm for people's life, and garbage disposal has become the focus difficult problem of social common concern.Past generally is to adopt to burn or landfill to rubbish, this obviously is not a long-term plan, because the pernicious gas that produces in burning process meeting atmosphere pollution, landfill is difficult for degraded, deal with the pollution that can cause improperly to underground water resource, and take a large amount of arable lands, and therefore must carry out sorting process, be recycled rubbish according to its composition, at first be exactly earlier rubbish to be carried out fragmentation.At present refuse breaking adopts high speed impact according to American-European countries more, is cut into main rotary crumbling method, perhaps use breaking ores to push, to impact, to be cut into main mine mechanism, because the municipal refuse of China mostly is packed mixed collection, based on garbage, water content height and complicated component, to be different from external rubbish be categorised collection, to be packaged as the master, so there are the following problems for the conventional garbage disintegrating machine: the energy consumption height, noise is big, the cost height, its serviceability needs further improvement.

The utility model content

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, cost is low, serviceability is good house refuse broken bag reducing mechanism.Its technical scheme is:

Comprise casing, feed hopper, baffle plate, discharging opening, be installed in the roller and the power set that rotate in opposite directions in the casing, feed hopper is positioned at the top of casing, baffle plate tilts to be fixed on the upper end inwall of casing, roller drives running by actuating unit, be evenly equipped with many serrated knives on it, it is characterized in that: two rollers drive the differential running by actuating unit, and its axis is parallel, many serrated knife rotation directions on two rollers are identical and form an angle with the axis of roller, constitute and shear.

Described house refuse broken bag reducing mechanism; the rotating speed roller outboard end that is positioned at casing faster is provided with slack adjuster; comprise quadrel; be fixed on the guide groove on the casing; spring and bearing; wherein the quadrel bearing fixing is on the roller axle; be installed in the guide groove; quadrel connects bearing along the outside of guide groove direction through spring; when running into the hard rubbish of bulk; quadrel can be in guide groove outside sliding compression spring, and then drive rotating speed faster the roller level outwards move, strengthen the gap between two rollers; protect rectangular serrated knife; when the hard rubbish of bulk falls behind down from the gap, quadrel return under the effect of spring, it is normal that recover again in the gap between two rollers.

Described house refuse broken bag reducing mechanism, two knife faces of every serrated knife are all angled, and its outer end connects and composes blade, and the sword peak of the serrated knife of formation shearing relation is relative on two rollers, to shearing of refuse bag.

The utility model compared with prior art, two rollers differential running under the driving of actuating unit of serrated knife is installed, the rubbish of pouring into from feed hopper falls in the shearing work chamber of two rollers the effect next part of baffle plate, pulverize by in opposite directions the serrated knife that changes being carried out broken bag to rubbish, the broken thoroughly nothing of assurance is slipped through the net, and the rubbish after the fragmentation is from the discharging opening discharge of roller below.Simple in structure, cost is low, high efficiency, and safe noise is little.

The specific embodiment

1, casing 2, feed hopper 3, baffle plate 4, discharging opening 5, roller 6, actuating unit 7, serrated knife 8, quadrel 9, guide groove 10, spring 11, bearing 12, roller axle 13, groove 14, blade

In the embodiment shown in Fig. 1～4: feed hopper 2 is positioned at the top of casing 1, baffle plate 3 tilts to be fixed on the upper end inwall of casing 1, two rollers 5 are installed in the casing 1 and drive the differential running by actuating unit 6, actuating unit 6 adopts motor, its motor shaft is fixedlyed connected with the roller axle 12 of roller 5, it is identical to be milled with many rotation directions on two rollers 5, become the groove 13 of 15 ° of angles with the axis of roller, its jut just constitutes serrated knife 7, two knife faces of every serrated knife 7 are all angled, its outer end connects and composes blade 14, constitute on two rollers 5 shearing relation the sword peak of blade 14 relative, to the shearing-crushing that carries out of refuse bag.Be protection serrated knife 7; rotating speed faster roller 5 outboard end that is positioned at casing 1 be provided with slack adjuster; comprise quadrel 8; be fixed on the guide groove 9 on the casing 1; spring 10 and bearing 11; wherein quadrel 8 bearing fixing are on roller axle 12; be installed in the guide groove 9; quadrel 8 connects bearing 11 along the outside of guide groove 9 directions through spring 10; when running into the hard rubbish of bulk; quadrel 8 can be in guide groove 9 outside sliding compression spring 10; and then roller 5 levels are outwards mobile faster to drive rotating speed; strengthen the gap between two rollers 5; protection serrated knife 7; when the hard rubbish of bulk falls behind down from the gap, quadrel 8 return under the effect of spring 10, the gap between two rollers 5 recovers normal again.
