Frame 220 is connect with driving device 250；Another spindle nose passes through the second mobile bracket 221 and is fixedly connected with first bevel gear 260；
Wherein, the driving device 250 uses hydraulic motor, is mounted on first movement bracket 220 by hydraulic motor bracket 251
On, it is connected to by oil pipe 252 with fueller.One spindle nose of rotary shaft 241 passes through the second mobile connection of bracket 221 second
Bevel gear 270.Transmission shaft 280, both ends pass through the outside that bearing block is mounted on the second mobile bracket 221, transmission shaft respectively
280 between first bevel gear 260 and second bevel gear 270；The both ends of the transmission shaft 280 are symmetrically fixedly installed first
Drive bevel gear 281 and the second drive bevel gear 282；Wherein, first drive bevel gear 281 and the first bevel gear
260 engaged transmissions, second drive bevel gear 282 and 270 engaged transmission of second bevel gear.260 turns of first bevel gear
When dynamic, the first drive bevel gear 281 follows first bevel gear 260 to rotate, the second drive bevel gear 282 and the first transmission cone tooth
Wheel 281 rotates synchronously, to drive second bevel gear 270 to rotate, and the rotation of second bevel gear 270 and first bevel gear 260
Turn contrary, make the second compressing roller 240 and the first compressing roller 230 synchronize rotate towards each other.In addition, first bevel gear 260 and
The specification of two bevel gears 270 is identical, and the first drive bevel gear 281 is identical as the specification of the second drive bevel gear 282, makes
Second compressing roller 240 is identical as the revolving speed of the first compressing roller 230.
The both side plate 211 of the precompressed room housing 210 is vertically arranged, and the two sides of each side plate 211 are fixed with two respectively
The vertical guide rail of item, guide rail are located at the inside of first movement bracket 220 and the second mobile bracket 221, first movement bracket
220 and second mobile bracket 221 moved respectively along the guide rail.
In the present embodiment, sliding block is installed in the inside of first movement bracket 220 and the second mobile bracket 221 respectively, and leads to
It crosses the sliding block and guide rail cooperation is slided.By taking the side where first movement bracket 220 as an example, the two sides point of side plate 211
Not An Zhuan two cylindrical slideways 213, the inside both ends of first movement bracket 220 are respectively welded sliding block 223, and sliding block 223 uses
Linear bearing built-in type sliding block, linear bearing 224 and the cooperation of cylindrical slideway 213 inside sliding block 223 slide, and make compressor
Structure sliding is more smooth.The cooperation of sliding block 223 and guide rail 213 limits the horizontal swing and pressure of first movement bracket 220 simultaneously
Offset of the compression apparatus along compressing roller axial direction.In sliding equipment (sliding block and guide rail) installation side of the second mobile 221 side of bracket
Formula is identical as first movement bracket 220.
In another embodiment, the lower end of guide rail 213 is arranged with buffer spring 214, declines in first movement bracket 220
When to 200 downside of precompression chamber, buffer spring 214 plays the role of buffering to two compressing rollers, prevent to compression integer type device
It causes to impact.Meanwhile identical buffering setting is done on the guide rail of the second mobile 221 side of bracket.
The bottom of precompressed room housing 210 is equipped with discharge valve 300, by discharge valve 300 by the molding stalk of precommpression
It is sent into baler.
Two compressing roller initial makeup locations are located at the predetermined extreme lower position of the vertical chute 212, when work, the straw of crushing
Stalk enters in precompression chamber 200 from receiving hopper 100 above precompression chamber 200, at this point, at the discharge valve 300 of 200 lower section of precompression chamber
In closed state.While the stalk of crushing enters precompression chamber 200, driving device 250 is opened, and driving device 250 passes through shaft coupling
253 connectiing shaft head 232 of device, driving the first compressing roller 230 rotation, drives first bevel gear 260 to rotate, the first drive bevel gear
281 follow first bevel gear 260 to rotate, and the second drive bevel gear 282 and the first drive bevel gear 281 rotate synchronously, and drive
Second bevel gear 270 rotates, so that the second compressing roller 240 be made to rotate；And first compressing roller 230 and the second compressing roller 240 it is opposite
Rotation.Stalk constantly feeds filling from top, and the stalk fed is in the rotation of the first compressing roller 230 and the second compressing roller 240
Turn and roller weight under the action of be pressed down against, be gradually uniformly paved with the pre- of the first compressing roller 230 and the lower section of the second compressing roller 240
200 space of discharge chambe；The self weight of first compressing roller 230 and the second compressing roller 240 and rotating inertia force pass through support rod 242
Working plate 244 is passed to, working plate 244 is contacted with stalk, is constantly compacted stalk downwards；First compressing roller, 230 He simultaneously
The stalk of second compressing roller, 240 lower section, generates upward reaction force to the first compressing roller 230 and the second compressing roller 240；Make
First movement bracket 220 and the second mobile bracket 221 are moved up by sliding block along guide rail, drive entire compression set gradually
Upward oscillatory type is mobile.Until the first compressing roller 230 and the second compressing roller 240 are moved to the predetermined extreme higher position of the vertical chute 212
When, precompression chamber control switch is opened, and opens the discharge valve 300 of 200 lower section of precompression chamber, pre-molding stalk relies on certainly
The densification sizing that baler is fallen under the action of weight and compressing roller is indoor, and compressing roller also falls on down the pre- of the vertical chute therewith
Determine extreme lower position, discharge valve 300 closes, completes a precommpression, repeat the above process, and realizes the compression pre- to stalk.
Although the embodiments of the present invention have been disclosed as above, but its institute not only in the description and the implementation
Column use, it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can hold
It changes places and realizes other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously
It is not limited to specific details and legend shown and described herein.
