Description

A kind of straw pulverizer

Technical field

The invention belongs to the straw processing equipment

Background technology

Along with the development of biomass energy and feed, light industry, chemical industry, an urgent demand design is a kind of to adapt to the size reduction machinery that different straws require.Yet, straw is pulverized general traditional pulverizer that uses at present, their general employings manually feed, straw feeds after moving knife and stationary knife cut-out are pulverized by the hammer leaf of rotation at a high speed after entering pulverizing chamber, again outside sieve sheet discharge machine, so do not cause the straw of cut-out uneven in length because artificial feeding has feeding unit again, not cutting off even of having also enters pulverizing chamber, so not only bring very big pressure to pulverizing, the straw that the fiber that has is long, be difficult to pulverize as cotton stalk, and difficultly separate, result in blockage and cisco unity malfunction by the sieve sheet.What have is provided with feeding unit at the feeding mouth place, and just as the feeding unit of traditional hay cutter, owing to this feeding unit is to be rotated by main shaft, because the speed of mainshaft of hay cutter is not high, it is not suitable for the requirement that straw is pulverized.Divide power to rotate speed change for solving employing pulverizing and the feeding unit that this difficult problem has, reached the purpose that requires, but this brings cost to increase greatly, this causes the processing cost increase again.Therefore also difficult the popularization.

The object of the present invention is to provide a kind of straw pulverizer, the traditional structure that it has broken traditional hay cutter has reached the requirement of crushed straw.Realize the transmission of single action power, the facility cost is low.

For achieving the above object, the present invention by the following technical solutions:

A kind of straw pulverizer mainly partly is made up of motor, frame, upper casing combination, lower casing combination, rotor portions dress, transmission mechanism, feeding conveying mechanism etc.Upper casing combination is made up of the upper casing seam and the tooth plate of packing in it, lower casing combination is made up of the lower casing seam and the sieve sheet of packing in it, rotor portions dress is made up of interior cross rotor disk and outer cross rotor disk and movable knife rack that power is housed, hammer leaf is housed between two cross rotor disks also to be separated with the hammer leaf spacer, transmission mechanism is to take turns speed change to main shaft by motor by bead apex, main shaft drives the rotation at a high speed of rotor portions dress, main shaft arrives the two stage speed change axle by bead apex wheel speed change simultaneously, again by the two stage speed change axle by gear to the three-step gear shift axle, drive down feeding lift-over to the level Four variable-speed shaft by three box couplings by two bevel gears commutations speed change by the three-step gear shift axle again and move.Following feeding is rolled and is reached main transmission by sprocket wheel and roll, and main transmission rolls that to drive passive transmission lift-over by conveyer belt moving.It is to reach the Pyatyi variable-speed shaft by gear graduation that last feeding is rolled, but the universal joint that contracts by the Shen again.Transmission mechanism reaches feeding and rolls, and last feeding is rolled and can be moved up and down according to what of feed quantity, realizes feeding up and down the conveying that compresses of rolling.

Frame is welded in the lower casing combination, and supports all transmission mechanisms.Rotor portions dress and feeding conveying mechanism, upper casing combination and lower casing make up an end by hinged, the other end is fixed by connecting ear, form the pulverizing chamber of sealing, overhaul or change other part as need, just pulverizing chamber can be opened as long as unclamp fastening connecting ear, so just installation and maintenance are put very much, motor is fixed on the frame.

The present invention has been because of having adopted unique transmission mechanism, thereby satisfied the requirement that straw is pulverized, and realized that the transmission of single action power can be cut off and pulverize to the straw of one to pulverize.Reached and saved the purpose that engine reduces the facility cost.

The specific embodiment

Below, describe specific structural details and the working condition that proposes according to the present invention in detail in conjunction with this accompanying drawing.

The present invention is mainly by motor (1) frame, the upper casing combination, the lower casing combination, rotor portions dress (30) (29) (28) (27) (26 (25 (24), transmission mechanism (2) (3) (4) (5) (6) (7) (8) (9) (31) (10) (11) (12) (13) (14) (15) (16) (17) (21) (23), parts such as feeding conveying mechanism (21) (22) (20) (19) (18) are formed, as shown in drawings, upper casing combination is made up of the upper casing seam and the tooth plate of packing in it, lower casing combination is made up of the lower casing seam and the sieve sheet of packing in it, rotor portions dress is made up of interior ten rotor disks (30) and outer ten rotor disks (27) and movable knife rack (26) that moving knife (25) are housed, hammer leaf (29) is housed between two cross rotor disks also separates with hammer leaf spacer (28), stationary knife (24) is fixed on the frame of charging aperture by the stationary knife seat.Transmission mechanism is (to be reached main shaft bead apex wheel (3) by bead apex wheel (2) and drive the rotation at a high speed of rotor portions dress by motor, the while main shaft reaches the two stage speed change axle by bead apex wheel (4) and triangle glue horn ring (6) and the adhesive tape of available pinch roller (5) adjusting simultaneously degree of tightness two stage speed change axle reaches the three-step gear shift axle by gear (7) and gear (8), commutate and pass through bevel gear wheel (11) speed change by a pair of slip bevel pinion (9) (10) on the three-step gear shift axle and by bevel gear zygote (31) to the level Four variable-speed shaft, drive to be lowered to by box coupling (12) (15) (17) again and roll (21) rotation, following feeding is rolled (21) and is reached main the biography by sprocket wheel (22) and roll (20), main transmission is rolled (20) and is rolled (18) rotation by the passive transmission of conveyer belt (19) drive, the realization straw transmits, (23) are rolled in last feeding is to reach the Pyatyi variable-speed shaft by gear (13) (14) by the level Four variable-speed shaft, reach feeding by telescopic universal joint transmission mechanism (16) again and roll (23) and go up feeding and roll (23) and can move up and down, feed realizations in and roll (23) and feed the conveying that compresses of rolling (21) down according to feed quantity.Frame is welded in the lower casing combination, and support all transmission mechanisms, rotor portions dress and feed conveying mechanism, upper casing combination and lower casing make up an end by hinged, the other end is fixed by connecting ear, form the pulverizing chamber of sealing, as the need maintenance or change other part, just pulverizing chamber can be opened as long as unclamp fastening connecting ear, so installation and maintenance are very convenient, motor (1) is fixed on the frame.

The present invention implements like this: straw is put on the conveyer belt (19), enter down feeding and roll (21) and last feeding is rolled between (23), the stationary knife (24) that the clamping straw enters feeding mouth under the two feeding reverse rotations of rolling is located to be cut off by epitrochanterian moving knife (25) and is entered pulverizing chamber, in pulverizing, be subjected to the strike of the hammer leaf (29) of rotation at a high speed and the rubbing of tooth plate and sieve sheet, pulverize under the collision effect, when reaching certain fineness, pass through outside the sieve sheet discharge machine.
