Description

Stalk chip machine

Technical field

The present invention relates to the machinery that agricultural crop straw is carried out to the chip processing, belong to agricultural machinery technological field.

Background technology

Agricultural crop straw, comprise climing rattan formula stalk, long-rod type stalk, soft stalk, hard stalk, large stalk, little stalk etc., is really of all kinds.Climing rattan formula stalk as: sweet potato stem and leaf, melon vine, climb ground grass etc.; The long-rod type stalk is as jute, cornstalk, lance stalk etc.; Some stalks are soft, become again hard stalk after drying.The fiber of some agricultural crop straw is very flourishing, and after the crops harvesting, these stalks are put to abandon and are difficult in the ground rot, and seriously affect next period plantation and the farming in soil.Some peasants, in order to process these stalks, take the mode of burning, and the crop straw burning in large tracts of land soil causes serious air pollution, and the peasant should consciously refuse this behavior, takes other mode Treating straw.

Adopting mechanical chip stalk is the universal method of people's Treating straw, and microscler stalk chip is become to segment, chip stalk body is more easily rotted, even if without putrefaction can not cause winding to the machinery of next period farming yet.General machinery is to gather in into carry out the work of chip stalk simultaneously, but these mechanical chip machines are just for a certain crops, can not be simultaneously for all stalks and forage, the stalk very flourishing for some fibre is helpless, particularly the problems such as card machine, winding, just occur in some dried stalk and forages.

Summary of the invention

In order to solve the processing problem of agricultural crop straw, I have invented a kind of stalk chip machine, this mechanical energy is applicable to being arranged on crop cropper the chip work of carrying out stalk when being gathered in, and chip fast, does not produce the phenomenon of winding, card machine, can be applicable to all agricultural crop straws; This stalk chip machine also is applicable to carrying out independently the chip work of various stalks.

Stalk chip machine the taked technical scheme of dealing with problems is: stalk chip machine comprises engine, conveying device, hand hay cutter materials device, engine provides the institute of chip dynamic, conveying device is oppositely to oppress with upper and lower two transfer rollers the device that the turning handle stalk advances to direction, and the hand hay cutter materials device is that the mode that moves up and down that the rotating manner of a runner is changed into to chopper is blocked into chip to the stalk arrived.

Stalk chip mechanism power resources are engines, and engine can be fuel oil type engine or electric type power machine, can be also a part of power that the grain header of stalk chip attaching that machine carries separates.The required power of stalk chip machine is mainly conveying device and cutting device; transmission of power from engine to the transfer roller conveying device is to complete by belt and belt pulley; the transmission process waste energy of belt is little; if run into the hard thing that is strayed in the process of transmission and when card machine; belt can skid, and engine has been protected in skidding effectively.

Conveying device is to consist of two transfer rollers side by side, between transfer roller rotating shaft of bottom and support, spring is installed, and makes these two transfer rollers can flexibly separate or contract closely, can tackle different types of stalk and forage.Two transfer rollers rotate backward and can and shift cutting device onto and be blocked the stalk inspiration chip machine arrived.These two transfer rollers are except the effect that transmission is arranged, and the effect of in addition large diameter stalk being flattened, vertically cutting bar, alleviated burden for cutting device carries out transversely truncation.Two transfer rollers are not hard-wired, mutual distance can change, and when running into a large amount of stalks and arrive, two transfer rollers are can be flexibly passive separates certain distance, can flexibly reduce distance again when stalk reduces, this elasticity is that the spring of between centers in being arranged on two transfer rollers completes.

Cutting device is conveying device and then.Pass through the compression of conveying device, vertically cut bar, transmit propelling, cutting device is blocked work in capacity ground very much.Block the motion that needs chopper upper and lower, this upper and lower moving can only be to be transformed by runner, because the power resources of this cutting device are the rotating manners come by the belt transmission.

The beneficial effect of stalk chip machine is: stalk chip machine utilizes the part power of engine transmission to drive two transfer rollers side by side and rotates backward, two transfer rollers are close by the spring compressing, two counter-rotational transfer rollers can pull the stalk cramping to shift hand hay cutter material mouthful onto, cut up with a hay cutter and break by chopper, the different types of stalk of energy chip; The part power that stalk chip machine also utilizes the engine transmission the energy rotated become chopper up and down moving energy carry out the work of chip stalk, improved the conversion ratio of kinetic energy, chip is strong fast.

Embodiment

Below in conjunction with accompanying drawing, stalk chip machine is further illustrated.

Section's problem of the confidential solution of stalk chip is the kinetic energy that becomes the kinetic transformation of engine rotation chopper to move up and down, and Fig. 1 is exactly the device addressed this problem.What in Fig. 1, there was a vertical runner (a 1) plane at the edge of a runner (1) stirs bar (2).If we arrange a coordinate system centered by the rotating shaft (9) of runner, this is stirred bar (2) and follows track that runner (1) circles while projecting on this coordinate system so, and this stirs bar (2) also in the reciprocating motion of carrying out the moving and left and right of upper and lower past double action in fact.If we arrange a horizontal draw-in groove (3) on a chopper movable handle (4), allow and stir bar (2) space that left and right moving is moving is arranged, but the space that (4) do not move up and down on the chopper movable handle, therefore it must do upper and lower moving together with chopper movable handle (4), and we have just captured moving up and down that runner (1) changes into like this.In Fig. 1, we see that chopper (6) mouthful is not flat mouth but the toothed edge of a knife, and the toothed edge of a knife is flourishing to fiber, hard stalk more penetrates the cut-out ability.

Fig. 2 is the overall structure fundamental diagram of stalk chip machine.In Fig. 2, two transfer rollers (14) are installed up and down side by side, the transfer roller in top (14) is in fixing transfer roller rotating shaft (17) fixed position, one of bottom is arranged on transfer roller rotating shaft (17) that can be up and down and above and by a spring (18) upwards heads on the transfer roller (14) on top and press and touch, and the rotation of the transfer roller of bottom (14) is rotated backward by transfer roller (14) the contact transmission on top.When having stalk to insert, two transfer rollers (14) can separate some distances passively, but the powerful elastic force of spring (18) can flatten stalk and shift hand hay cutter material mouthful (7) onto by the vertical slitting of the annular edge of a knife on transfer roller (14) again.The rotational power of the transfer roller of Fig. 2 middle and upper part (14) is provided by the small belt pulley (11) of engine, and small belt pulley (11) reaches and makes transfer roller (14) than the purpose of slow rotation by the big belt pulley (13) on belt transmission transfer roller (14).Chopper in Fig. 2 (6) power set be also by with the coaxial engine of small belt pulley (11) on gear (10) power is provided, in figure, the disk of a travelling gear (8) and gear (10) on engine are vertical contacts interlock, the rotatory force of engine laterally is delivered to runner (1) by rotating shaft (9), runner (1) is rotated.The rotation formula of runner (1) changes into the moving up and down of chopper (6) and is described above form.Stalk chip machine in Fig. 2 can work alone, and also can be installed to harvesting on one side on grain header and carry out the chip work of stalk simultaneously.
