Abstract

The utility model relates to a crushing device for plant stalk, specifically to a double-knife straw crusher. The double-knife straw crusher comprises a crushing chamber and a pair of crushing rollers parallelly arranged in the crushing chamber, a feed inlet is arranged above the crushing roller, a plurality of knife flywheels are arranged on each crushing roller, the knife flywheels on the two crushing rollers are staggered; a plurality of protuberant knife teeth in radial direction are equipped on the knife flywheel, and the knife teeth on one crushing roller is overlapped with the knife teeth on another crushing roller in radial direction. The utility model has the advantages of simple structure, good crushing effect, and long service life of knives.

Description

The double knife roller straw crusher

Technical field

The utility model relates to a kind of breaker that is used for plant stem, specifically is a kind of double knife roller straw crusher.

Background technology

Can be used as fuel of heat supply or paper making pulp raw material after the fragmentation of crops cane, straw crusher is used for broken crops cane equipment exactly.Common straw crusher, its crusher members is generally single roll structure, promptly on broken roller rotary cutter is installed, and installs and fixes cutter simultaneously on frame, and rotary cutter passes through the relative shear campaign of its longitudinal end and fixed cutting tool with the plant stem shearing-crushing.In this structure, plant stem relies on shearing force with its fragmentation fully, and tool wear is very fast, and service life is low; This in addition crumbling method needs special feeding mechanism that cane is sent into cutting edge, and whole device is complicated, the equipment cost height.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of simple in structure, crushing effect is sent out, cutter life is long double knife roller straw crusher is provided.

Double knife roller straw crusher of the present utility model includes a crusher chamber and pair of parallel and is installed in breaker roll in the crusher chamber, the breaker roll top is a charging aperture, be placed with a plurality of cutterheads on each root breaker roll, the cutterhead position in the axial direction on two breaker rolls is interlaced; Cutterhead is provided with the cutter tooth of several radial projection, and cutter tooth on breaker roll and the cutter tooth on another root breaker roll have lap diametrically.

The utility model has the advantages that: 1, when work, two breaker roll direction of rotation are opposite, material is sent rolling up naturally of two rotors pass through fracture area down, and need not special feeding mechanism; 2, the rotating speed one of two breaker rolls is fast, one slow, thereby can make cutter tooth side adjacent on two breaker rolls produce relative translation, the side that utilizes cutter tooth with cutting with pull the mode that combines and carry out fragmentation, can reduce the wearing and tearing of cutter to material, prolongs its service life; 3, since the cutter tooth on two breaker rolls at axial interlaced, radially equitant cutter tooth, the common relative motion of a plurality of like this cutters tooth can be played the effect of clamping straw, thereby also saved forage clamping device in the conventional cutting equipment, and simplified device structure, reduced cost.

Description of drawings

Fig. 1 is a cross section structure schematic diagram of the present utility model;

Fig. 2 is the vertical structure schematic diagram of two breaker rolls.

Embodiment

As shown in the figure, the crusher chamber of double knife roller straw crusher interior 1 is equipped with the breaker roll 2 of pair of parallel, and the breaker roll top is that cutterhead 4 position in the axial direction on 3, two breaker rolls of charging aperture is interlaced; There is the cutter tooth on 5, two breaker rolls of cutter tooth of four radial projection to have lap diametrically on each cutterhead.

The utility model in the course of the work, two rotor 2 reverse rotations, in the view of Fig. 1, the rotor in left side turns clockwise, the rotor on right side is rotated counterclockwise, and the rotating speed one of two rotor is fast, one slow.Like this, the material that enters from charging aperture promptly is involved in downwards under the effect of two rotors, obtains fragmentation by relatively moving of cutter tooth on two rotors simultaneously.

Claims

1. double knife roller straw crusher, it is characterized in that: it includes a crusher chamber (1) and pair of parallel and is installed in breaker roll (2) in the crusher chamber, the breaker roll top is charging aperture (3), be placed with a plurality of cutterheads (4) on each root breaker roll, the cutterhead position in the axial direction on two breaker rolls is interlaced; Cutterhead is provided with the cutter tooth (5) of several radial projection, and cutter tooth on breaker roll and the cutter tooth on another root breaker roll have lap diametrically.
