Abstract

The utility model relates to a shredding machine, in particular to a double-shaft shear-type shredding machine, belonging to the technical field of shredding machines. The double-shaft shear-type shredding machine is characterized by comprising a pair of parallel main shafts (3), each of the main shafts is provided with a plurality of four-claw shredding blades (4) in the axial direction, and the four-claw shredding blades (4) on the two main shafts are arranged in a staggered manner, and the adjacent blades on the same main shaft (3) are deflected for a certain angle sequentially; the double-shaft shear-type shredding machine also comprises a shredding box which surrounds the outsides of the pair of the main shafts (3) and is provided with an opening at the upper end; and the main shafts (3) rotate oppositely under the driving of a power source. According to the shredding machine, the four-claw shredding blades on the two main shafts are arranged in a staggered manner, the adjacent blades on the same main shaft are deflected for a certain angle sequentially, and the blades on the other main shaft rotate oppositely, so that the operations of grabbing and shredding waste materials are realized.

Description

A kind of Double-shaft shearing shredder

Technical field

The utility model relates to a kind of shredder, specifically, is a kind of Double-shaft shearing shredder, belongs to the shredder technical field.

Background technology

Shredder is exactly a kind of as machine in small, broken bits, is generally used for and processes crude raw material or leftover pieces, makes its size more tiny.This shredder is a kind of heavy duty equipment that is applicable to reclaim the waste materials such as the broken film of industry, plastics, rubber tyre, timber, can be used for the recycling of the materials such as bulk solid material, plastic containers, plastic sheeting, fiber and paper, also availablely tear up common waste material, dependable performance, easy to maintenance, security is good.

Representative example is that the leftover pieces of plastics or rubber are torn up and granulate after the raw material melting afterwards, is used for again making plastic bottle, tire or dustbin etc.Shredder is applied to plastics recovery regeneration industry, the fragmentation of be usually used in waste product heavy caliber PE plastic pipe, bundled packing plastic sheeting, piling up greatly plastic sheet and head material.

Existing Double-shaft shearing shredder, it tears up the form that blade is generally three-jaw, and the blade that tears up on two main shafts is installed side by side, and two main shafts rotate in opposite directions, are torn up action, and it is lower that this shredder is picked up efficiency, and it is poor to tear up effect.

Summary of the invention

The technical problem that the utility model solves is: existing Double-shaft shearing shredder, and it tears up the form that blade is generally three-jaw, and the blade that tears up on two main shafts is installed side by side, two main shafts rotate in opposite directions, torn up action, it is lower that this shredder is picked up efficiency, and it is poor to tear up effect.

The utility model is taked following technical scheme:

A kind of Double-shaft shearing shredder, comprise and configure the main shaft of pair of parallel vertically separately a plurality of four paws and tear up blade, and the four paws on two main shafts tears up the blade interlaced arrangement, adjacent blade deflection certain angle successively on same main shaft; Also comprise and tear hopper, the described hopper that tears is trapped among a pair of main shaft outside, upper end open; A pair of main shaft rotates in opposite directions under the drive of power source.

The characteristics of the technical program are: the four paws on a pair of main shaft is torn up to the blade interlaced arrangement, and adjacent blade deflection certain angle successively on same main shaft, the blade on an other main shaft on the other side is opposite direction rotating simultaneously, realizes the crawl to waste material, tears up.

The frame that also comprises reassembling type, described frame is formed by connecting by the metal rod bolted.

Described power source is motor, also comprises decelerator, and described decelerator is connected with main shaft.

Also comprise feed hopper, described feed hopper is positioned at the described hopper top of tearing.

The value of described deflection certain angle is 30 °.

The beneficial effects of the utility model are:

1) better effects if of tearing up the blade crawl of shredder.

2) the shredder operating efficiency is higher.

3) it is better that shredder tears up effect.

4) structure is ingenious, is easy to realize.

The specific embodiment

Below in conjunction with specific embodiment, the utility model is further illustrated.

Referring to Fig. 1, this Double-shaft shearing shredder adopts driven by servomotor two main shafts in both sides to carry out low speed rotation and tears up waste material.On main shaft 3, arrange side by side a plurality of four paws to tear up blade 4, utilize mechanical system to fix, by the rotation of main shaft 3, the four paws on both sides tears up blade 4 and captures continuously waste material, and waste material is torn up.Tear the hopper body with hopper utilization organize bolt more and be connected.

Main shaft 3 utilizes solid box to support, and a plurality of four paws is installed side by side and tears up blade 4.Main shaft 3 two ends are connected with decelerator, motor 1 by decelerator by transmission of torque to main shaft 3, main shaft 3 drives and tears up blade and be rotated, a pair of blade opposite direction rotating that tears up, work to tear up waste material.

Referring to Fig. 2, tear the hopper body two main shafts 3 are sealed, to guarantee the security performance of the process of tearing up.

Referring to Fig. 1, adopt the split-type design, the whole hopper body that tears has four risers, utilizes bolt to be connected, convenient disassembly.Hopper is tearing above the hopper body, by it, collects waste material, and waste material enters and tears up chamber under the effect of deadweight.Also can utilize free-standing feed mechanism feeding.Hopper and this hopper body are connected with many group bolt connection pieces, during installation, utilize the crane hopper of slinging to be installed.

Frame 5 also takes split-type to connect, and specifically assembling mode is to adopt bolt, and metal rod is fastenedly connected, and forms frame 5.

Adopt on main shaft 3 and many four paws arranged side by side is torn up to blade structure, adjacent knife blades 30 ° of deflections successively, the blade on an other main shaft on the other side is opposite direction rotating simultaneously, realizes the crawl to waste material, captures efficiency high, and security performance is good.
