Embodiment
Below, by exemplary embodiment, the present invention is specifically described.Yet should be appreciated that element, structure and the feature in an embodiment also can be attached in other embodiment valuably in the situation that further not narrating.
Referring to Fig. 1 and Fig. 2, according to a kind of straw cutting apparatus 20 of the present invention, be connected to the rear of tractor.By reference to the accompanying drawings, straw cutting apparatus 20 also comprises: transmission device 30, for transferring power, is connected to the afterbody of the rear portion output shaft of described tractor; And equipment 40, for crushing straw and by the stalk after pulverizing, from following broken cash discharging opening 431, throw also field.
Shown in Fig. 3 a-3b and Fig. 4 a-4b, be worth being with pointing out, straw cutting apparatus of the present invention has two kinds of assembly connection forms, has effectively reduced complete machine width, is conducive to transportation.Specifically, when described straw cutting apparatus is in running order, equipment 40 is detachably connected to the sidepiece of described transmission device 30; When described straw cutting apparatus is during in travel position, described equipment 40 is removably connected to the afterbody of described transmission device 30.
It should be noted that described gear shift device 32 also comprises: gearbox 321, its one end is connected with the rear portion output shaft of described tractor; And a plurality of cone pulleys 322 and the belt that matches with it, one of them cone pulley is connected with the output shaft of described gearbox.
By adjusting described belt, the rotating speed of described flywheel is adjustable, thereby plays the effect of overload protection.Specifically, the most area in Xinjiang, when in spring and summer during season, the stalk toughness in field is larger, at this moment can, by regulating the belt that match with cone pulley, make the rotating speed of flywheel become large, thereby be with movable cutter set crushing straw.When in autumn and winter season, the stalk toughness in field is less, and more slow-revving cutter group gets final product crushing straw, at this moment can, by regulating the belt matching with cone pulley, the rotating speed of flywheel be diminished.So, by adjusting the transmission of belt, can play the effect of overload protection.
Further, equipment 40 also comprises: pulverize washboard 46, be arranged on the broken cash discharging opening position of described workpiece housing, in order to improve the degradation rate of stalk.In order to prevent the hard thing damage cutter groups such as stone, equipment 40 is also provided with: cutter fence 47 is protected in front portion, be arranged on the position of the stalk charging aperture of described workpiece housing, wherein said front portion is protected has a fixed gap on cutter fence, its one end towards stalk charging aperture has the pars convoluta of tilting upward 471, can be so that machine lifts while running into hard thing.Equipment 40 also comprises: flywheel shield 48, is located at the outside of described flywheel, and is positioned at the outside of described workpiece housing, in order to protect flywheel not to be damaged.
Meanwhile, equipment 40 also comprises: the second work is travelled and used connector 411b with connector 411a and second, be separately positioned on described support bracket fastened sidepiece and end, and travel and cooperatively interact and be connected with connector 311b with connector 311a and first with described the first work.
According to a preferred embodiment of the invention, the first connector 311a for work, the second work are travelled and are travelled and be respectively two groups with the connection otic placode of connecting hole with connector 411b with connector 311b and second with connector 411a, first.Should be appreciated that above-mentioned first, second work is not unique by structure and the form of connector and first, second use connector that travels, those skilled in the art can make various distortion according to actual needs.
In order to understand better the present invention, the job step of straw cutting apparatus of the present invention will specifically be introduced below.
1. enter while working, state while making complete machine present work, equipment side is suspended to transmission device, and integrality is that equipment is in a side of tractor.
2. power passes to equipment (belt transmission plays overload protective function) by tractor rear portion output shaft by transmission device.
When 3. complete machine advances along with tractor, cotton stalks etc. need the stalk of chopping and returning to enter from working portion front portion, cutter group, pulverizing washboard and workpiece housing coordinate crushed stalk, and the rotary action of cutter group can throw the stalk after pulverizing to ground from the opening at rear portion.
While 4. working, stalk can enter into equipment smoothly, and some protect stone etc. the large object in cutter fence gap than front portion and will make to protect from front portion cutter fence bottom and pass through, and working portion is raised, thereby avoided cutter group to damage.
In sum, according to straw cutting apparatus of the present invention, owing to having two kinds of assembly connection forms, in the time of in working order, equipment hangs the sidepiece of transmission device; When travel position, equipment is articulated to the afterbody of transmission device, effectively reduces complete machine width, is conducive to transportation.Running part has increased the transmission of belt one-level, can prevent from when cutter group is subject to resistance damaging, thereby play the effect of overload protection.By setting up front portion, protect cutter fence, can prevent the hard thing damage cutter groups such as stone.By adopting indented knife and pulverizing washboard, strengthen crushing effect.
Be appreciated that the present invention is described by some embodiment, those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
