Abstract

A straw-stalk pulverizer is composed of a counter weight type belt wheel, a bearing unit, a mainshaft, a machine frame, a casing, a feeding hopper with the fixed knife at its bottom inlet, a discharging hopper, and a rotor assemblage consisting of rotor disc with two curved knives, a supporting frame, and 4 groups of rotary pendulum plates installed via pins.

Description

Stalk crasher

One, technical field:

The invention belongs to feed processing machinery, especially relate to a kind of stalk crasher.

Two, background technology:

Straw utilization is a hot issue for many years in vast rural area, since last century end, country has dropped into a large amount of funds and straw utilization has been studied and helped some straw utilization research projects, as: gasifying stalk, fermentation process, straw-returning, the research of many projects such as straw board and test, but really can accomplish the few of sustainable development, one of trace it to its cause, be in the pulverizing of stalk, to have run into certain technology barrier, the functional requirement that the pulverizer that generally use in present rural area does not still reach crushing straw, because that still is last century six, the seventies is for pulverizing grain, soya-bean cake, dried sweet potato and so on, and the disintegrating apparatus that grows up, though this class pulverizer also can be pulverized processing to stalk, but the preparation processing before must pulverizing stalk, as pressing, hand hay cutter processing, and it is low to pulverize efficient, causes this class amount of crushing straw big, the thing cost of low value is too high and lose more than gain.

Three, summary of the invention:

The purpose of this invention is to provide a kind of need not stalk is done any anticipating, be i.e. the special-purpose pulverizer of the high-efficiency energy-saving straw of practicable pulverizing.

The technical scheme that the present invention takes is, it is by belt pulley, bearing block, main shaft, frame, housing, feed hopper, discharge bucket and rotor assembly are formed, housing is in the rotor assembly outside, feed hopper and discharge bucket are installed on the housing, housing and rotor assembly are in a side of bearing block, belt pulley is in the opposite side of bearing block, belt pulley and rotor assembly are installed on the main shaft, belt pulley is the counterweight belt pulley, rotor assembly contains a rotor disk, two bracing frames and four groups of lappets that can rotate, rotor disk one side is equipped with two tulwars, opposite side connects bracing frame by four Xiao's axles, and lappet is installed on Xiao's axle, and feed hopper is fan-shaped, stationary knife is equipped with at bottom inlet place at feed hopper, and the sieve sheet is contained in the border between housing inboard and the rotor assembly.

The invention has the beneficial effects as follows, from the pulverization principle of stalk, current pulverizer is improved, is the plant equipment of carrying out crushed stalk specially, and processing cost is low, the efficient height, and energy consumption is low, and is simple in structure, easy to operate, and maintenance is easily, and is safe and reliable.

Four, description of drawings:

Fig. 1 is the main cutaway view of stalk crasher of the present invention;

Fig. 2 is the left view of stalk crasher of the present invention shown in Figure 1;

Fig. 3 is the vertical view of stalk crasher of the present invention shown in Figure 1.

Five, the specific embodiment:

From the main cutaway view of stalk crasher of the present invention shown in Figure 1 as can be seen, the present invention is by belt pulley 14, bearing block 10, main shaft 13, frame 16, housing 1, feed hopper 7, discharge bucket 17 and rotor assembly 8 are formed, housing 1 is in rotor assembly 8 outsides, feed hopper 7 and discharge bucket 17 are installed on the housing 1, housing 1 and rotor assembly 8 are in a side of bearing block 10, belt pulley 14 is in the opposite side of bearing block 10, belt pulley 14 and rotor assembly 8 are installed on the main shaft 13, bearing block 10 is the connecting shaft bearing, promptly two bearings 15 are fixed on the bearing block, guaranteed the concentricity in installation, transmission effect and service life have been increased, lubricating cup 11 is arranged on the bearing block 10, and bearing block 10 is fixed on the frame 16 by four bolts 22, and main shaft 13 1 sides connect belt pulley 14, opposite side connects rotor assembly 8, in order to increase inertia, save power, belt pulley 14 is designed to contain the belt pulley of counterweight 12.Rotor assembly 8 comprises a round rotor dish 6, two cross supporting frames 9 and four groups of lappets 3, rotor disk 6 and bracing frame 9 are fixed on the main shaft 13,120 degree tulwars 5 of two symmetries promptly are housed facing to a side of charging aperture in a side of rotor disk 6, opposite side connects two cross supporting frames 9 by four Xiao's axles 4, four groups of lappets 3 are installed on four Xiao's axles 4, lappet is designed to stepped shape, and two is Shape, to increase crushing effect, lappet 3 can rotate around Xiao's axle 4, and when rotor assembly rotated, lappet 3 was thrown away automatically, and present embodiment has designed 14 lappets, and two opposite groups equates that every group is 3 or 4.From Fig. 2 and shown in Figure 3, facing to rotor assembly 8 direction of rotation one side, a slice stationary knife 21 is housed in the bottom and housing 1 junction of feed hopper 7, the gap on stationary knife 21 and the rotor disk between the tulwar 5 can be adjusted.Feed hopper 7 is designed to fan-shaped tangential feeding structure, has improved operating efficiency.Housing 1 is a spiral shaped housing, be divided into lower house, feed hopper 7 is installed on the upper shell, discharge bucket 17 is installed on the lower house, is connected with connecting bolt 20 with engaging lug 18 between the last lower house, and respectively there is a slice sieve sheet 2 last lower house inboard, make the border discharging, be drilled with several wind holes 19 in the lower house middle-end outside, increased intake, make whole housing form a blower fan.For the ease of connecting material, discharge bucket 17 exits are designed to two discharge holes, and an available sideboard blocks one of them.Technological process of the present invention is: stalk is entered by feed hopper, by cutting off between tulwar and the stationary knife, is pulverized at a high speed by lappet, rotates the blast of generation at a high speed by rotor assembly, discharges from the sieve sheet, discharges the material finished product by discharging opening.
