Abstract

A double-casing axial-flow grinder belongs to the technical field of manufacturing agricultural machinery, and consists of a casing, a front axle, a rear axle, a cutting knife, a hammer slice, a fixed knife, a screen cylinder and a blower, wherein a connecting bearing is arranged in the casing; one end of the front axle and one end of the rear axle are mounted on the connecting bearing; the cutting knife is fixed on the front axle; a hub disc perpendicular to the rear axle is fixed on the rear axle and connected with the hammer slice through a pin shaft; the fixed knife is fixed on the inner wall of the casing; the screen cylinder is mounted in the casing and surrounds the cutting knife and the hammer slice; the blower is mounted at the rear part in the casing; a screen is arranged between the blower and the screen cylinder in the casing; a feed port is formed at the front end of the casing; and a discharge port is formed at the rear end of the casing. When the grinder is in operation, the front axle and the rear axle starts to rotate to drive the cutting knife, the hammer slice and the blower; the cutting knife cuts straws into sections; and the sections of the straw are hit through the cooperation of the fixed knife and the hammer slice to be flours, penetrate the screen cylinder and the screen, and then are sent out from the discharge port by the blower. The double-casing axial-flow grinder has the advantage of convenient operation and stable running, and can effectively grind straws.

Description

Double type axial flow pulverizer

Technical field:

The utility model belongs to agricultural machinery manufacturing technology field, is a kind of straw millstone.

Background technology:

In vast rural area, maize straw directly is used as fuel and is used to cook and warm oneself, and it is low to be beneficial to rate, causes waste, and the while is contaminated environment also.With crushed stalk, be used then can burn very abundant with other fuel again, improve the thermal efficiency, and alleviated pollution widely.Stalk still is the main feed of livestock, and the stalk flour then helps livestock digesting and assimilating stalk.At present, the reducing mechanism at stalk yet there are no report.

Summary of the invention:

The technical problems to be solved in the utility model is to disclose a kind of double type axial flow pulverizer that is used for crushing straw.

The scheme of the utility model technical solution problem is to adopt housing, front axle, rear axle, chopper, hammer leaf, stationary knife, screen drum and blower fan constitute double type axial flow pulverizer, front axle is in the front portion of housing, one end stretches out the front side of housing, enclosure interior has connection bearing, the other end of front axle is contained on the connection bearing, rear axle is at the rear portion of housing, one end stretches out the rear side of housing, the other end of rear axle is contained on the connection bearing, be fixed with chopper on the front axle, be fixed with the reel vertical with rear axle on the rear axle, reel connects hammer leaf by bearing pin, be fixed with stationary knife on the inner walls, the stationary knife position is corresponding with hammer leaf, and stationary knife and alternately arrangement of hammer leaf, and screen drum is housed in the housing, screen drum surrounds chopper and hammer leaf, blower fan is equipped with at rear portion in the housing, in the housing between blower fan and the screen drum filter is arranged, and the housing front end has charging aperture, blower fan is corresponding with charging aperture, and the housing rear end has discharging opening.During work, start the rotation of front axle and rear axle, drive chopper, hammer leaf and blower fan, stalk is sent in the housing by charging aperture, and chopper cuts up with a hay cutter into section with stalk, cooperates with hammer leaf through stationary knife to impact again, form the flour shape, see through screen drum and filter and send by discharging opening by blower fan.

Move for the ease of pulverizer is whole, walking mechanism is installed at housing bottom.

Originally have following characteristics:

1, double-deck casing: the outer protective casing of one deck, two layers of sieve formula inner casing play outputting material screening filtration.

2, at first material is carried out preliminary treatment after the charging by the hand hay cutter section apparatus.

3, grinder adopts axial flow crushed work principle, and flow process is: material suction → pulverizing → screening step by step → pulverizing → output again.

4, the material output system adopts centrifugal output, has increased the material fan-out capability, avoids material stall phenomenon.

5, transmission aspect adopts multistage same power transmission, makes each working speed of equipment reach allocation optimum, and uses same power source, reduces equipment energy consumption.

6, power can use motor or use tractor dynamic power, is convenient to more pulverize in the field.

7, can separate with walking mechanism, be convenient to the user at the different location comminuting matter.

8, crushed work efficient height, model machine crushing rear material granularity can reach φ 3～φ 5mm, operating efficiency be 2.5 tons/time (pulverizer of market sale now, if reach this granularity, operating efficiency only be 1～1.8 ton/time).

9, product can be according to user's request, but adjusts the crushing rear material granule size.

The utility model can be pulverized powder of straw effectively, and is easy to operate, stable, and cost is low.
