Abstract

The utility model discloses a sawtooth hammer sheet type efficient straw grinder and aims at solving the problems that an existing straight-panel stripe-type steel-plate hammer-sheet straw grinder has the defects that the contacting face of a hammer-sheet straight-panel blade face and straw is small, utilization rates of the blade face is low, acute blades and acute angles of hammer sheets are easy to wear or damage, service life is short, and working efficiency is directly influenced by frequent replacement of the hammer sheets, and the like. The sawtooth hammer sheet type efficient straw grinder comprises a base, a motor and a main machine body. Hammer sheets arranged on a main transmission shaft of the main machine body are composed of a plurality of sawtooth double-blade hammer sheets distributed on the main transmission shaft. The length ratio of two acute edges of each sawtooth on the hammer sheets is 2:1. The sawtooth hammer sheet type efficient straw grinder has the advantages that structures of the hammer sheets are reasonable; the number of acute blades of the hammer sheets is increased by 58.6% that of acute blades of normal hammer sheets; production rate is improved by 30% at the same input power; service life of the hammer sheets is prolonged; and power energy is saved. Further, a material absorption fan is arranged outside the main machine body, combined with the main machine body into a whole, and connected with a gas-material separator, and therefore operation and management of materials after processed are simplified, flying of dust after the materials are grinded is avoided, and production operation conditions and environments are improved.

Description

Saw hammer sheet efficient stalk machine for cutting vermicelli

Technical field:

The utility model relates to a kind of cutting mill, relates in particular to a kind of saw hammer sheet efficient stalk machine for cutting vermicelli.Be applicable to farming and animal husbandry and biomass solid fuel processing industry, belong to the cutting and grinding machine and make the field.

Background technology:

Present stalk cutting mill roughly is divided into two kinds: a kind of is the vertical bar beater disintegrating machine of machine feeding mouth band cutting knife; Also having a kind of is that feeding mouth is not with the vertical bar beater disintegrating machine of cutting knife.The hammer leaf that above-mentioned two kinds of machines adopt is straight board lath formula steel plate structure; Because using this kind machine pulverizes stalk; Main high speed rotation by hammer leaf is pulverized, and for the hammer leaf that straight board lath formula steel plate constitutes, through the hammer leaf with sharp sword and acute angle one side stalk is cut, impacts and pulverize; The straight plate sword of this kind face hammer leaf and stalk contact-making surface are little, its sword face utilization rate is low, and cause the waste of power and energy; And its pliability sharp sword and acute angle poor, that make hammer leaf are easy to be worn or damage; Because service life is short, needs often to change hammer leaf, and directly influence operating efficiency.

Summary of the invention:

The utility model is in order to solve present stalk cutting mill, because the hammer leaf that adopts is a straight board lath formula steel plate, in the process of processing, has the straight plate sword face of hammer leaf and the stalk contact-making surface is little, make sword face utilization rate low, and causes the waste of power and energy; And its pliability is poor, makes the sharp sword of hammer leaf and acute angle be easy to be worn or damage; And service life is short, needs often to change hammer leaf, directly influences technical problems such as operating efficiency, and a kind of saw hammer sheet efficient stalk machine for cutting vermicelli is provided, and it comprises base, motor and main body, and said motor and main body are installed on the said base; Said main body is by lower body, and operate portions and upper casing are formed; In the said lower body sieve plate is installed; The final drive shaft of said operate portions is connected with motor-driven; Moving cutting knife, hammer leaf baffle plate and hammer leaf are housed on said final drive shaft; Feed hopper, cutter and acia are installed on the said upper casing; Said hammer leaf is made up of the multiple blade saw profile of tooth twolip hammer leaf that is distributed on the final drive shaft, and the length ratio of two sharp edges of each sawtooth on the said zigzag twolip hammer leaf is 2: 1, and promptly the length of long sharp edge is 2 times of short sharp edge length; The long sharp edge of said sawtooth is towards the lateral direction in final drive shaft axle center; The short sharp edge of said sawtooth is towards the final drive shaft axis direction.

Characteristics of the utility model and beneficial effect: hammer leaf is rational in infrastructure, energy-conservation, high efficiency, long service life; Main body is furnished with the suction blower fan outward, and is connected operation and the management of having simplified processing back material with gas-material separator, has improved the production operation conditions and environment.Be embodied in:

The zigzag hammer leaf that adopts is compared with straight-plate-type steel plate hammer leaf, and its sharp sword length has increased by 58.6%.Like this, under equal rotary speed, increased the contact-making surface of hammer leaf and stalk cutting; Increasing the flexible wearing and tearing that reduce hammer leaf simultaneously of hammer leaf, the service life of having improved hammer leaf is to the greatest extent and under equal input power; Boost productivity more than 30% the corresponding power source of having practiced thrift.

Through the suction blower fan is housed outside main body, and be communicated with, can pulverized material be sent into gas-material separator through blower fan and carry out the gas material and separate, made things convenient for the collection of material behind the powder, transported and deposit with the gas-material separator of outside.Also avoid the dust from flying of material behind the powder, improved the production operation conditions and environment.

The specific embodiment:

Referring to Fig. 1-Fig. 3, saw hammer sheet efficient stalk machine for cutting vermicelli, it comprises base 1, motor 2 and main body, said motor 2 is installed on the said base 1 with main body; Said main body is by lower body 3, and operate portions and upper casing 11 are formed; In the said lower body 3 sieve plate 4 is installed; The final drive shaft 5 of said operate portions drives with motor 2 and is connected; Moving cutting knife 8, hammer leaf baffle plate and hammer leaf 9 are housed on said final drive shaft 5; Feed hopper 7, cutter 6 and acia 10 are installed on the said upper casing 11; Said hammer leaf 9 is made up of the multiple blade saw profile of tooth twolip hammer leaf that is distributed on the final drive shaft 5, and the length ratio of two sharp edges of each sawtooth on the said zigzag twolip hammer leaf is 2: 1, and promptly the length of long sharp edge is 2 times of short sharp edge length; The long sharp edge of said sawtooth is towards the lateral direction in final drive shaft 5 axle center; The short sharp edge of said sawtooth is towards final drive shaft 5 axis directions.

Wherein: the preparation of the zigzag twolip hammer leaf in the saw hammer sheet efficient stalk machine for cutting vermicelli; Adopt the thick multi-disc of manganese steel plate of high abrasion 4mm; With the line cutting zigzag is processed on its two long limits; The length ratio of two sharp edges of each sawtooth is 2: 1, and promptly the length of long sharp edge is 2 times of short sharp edge length; The long sharp edge of sawtooth is towards the lateral direction in final drive shaft 5 axle center during installation; The short sharp edge of said sawtooth takes off towards one.

Because the zigzag hammer leaf adopts the twolip structure, when the sharp sword of one side need be changed, can twolip be fully used through turning hammer leaf.

Outside main body, also be furnished with suction blower fan 12, the impeller of said suction blower fan 12 is installed on the final drive shaft 5, just becomes one with main body, and is communicated with the gas-material separator of outside.Make pulverized material send into gas-material separator through the blower fan sucking-off at any time and carry out the separation of gas material, made things convenient for the collection of material behind the powder, transported and deposit.Also avoid the dust from flying of material behind the powder, improved the production operation conditions and environment.
