Abstract
The utility model provides a whole set of technical project of a high efficiency hay cutter to improve the state of the art of various existing hay cutters of complicated structure of the transmission mechanism, strict request of the manufacturing engineering and high manufacturing cost, and to overcome the defect of possible damage to the transmission mechanism for coping with large feed quantity. The technical project changes the transmission mechanism which makes the working-spindle served as a steering transmission mechanism-a transmission shaft, and separates the working-spindle from the steering transmission mechanism to realize power transmission by a transmission belt as a transmission mechanism. Therefore, the cost is greatly reduced and the defect of the damage resulted from drastic increase of load to the transmission part in the case of large feed quantity is solved to reduce the failure rate of the machine.
Description
Technical field
The utility model relates to agricultural hay cutter technology, in particular the improvement technology of the pan feeding running part in the hay cutter.
Background technology
Existing various hay cutter device, it is power-transmitting part that the operation of its pan feeding part has generally been adopted with the work spindle, by the gearbox that turns to the hard type of belt drive that bevel gear and speed changing transmission gear mechanism constituted on the work spindle, reach two and parallelly go into the reverse material folding of material roller and rotate operation.The structure of this existing transmission mechanism constitutes the matching requirements that cost consumption is big, strictness is arranged, and is that it causes the abnormal high main cause of computer system market price; In addition in actual use, the following technological deficiency that this transmission mechanism also exists: once the feeding material is too many, it is excessive because of load to go into material roller, himself and variable transmission mechanism can't turn round, work spindle this moment rotating operation under the direct drive of electromotor still, steering drive axle and pan feeding roll shaft can twists under the powerful inertia effect of work spindle, bending is out of shape.The fact shows, the overwhelming majority is this owing to the pan feeding roller mechanism causes damage to feed quantity is comparatively responsive in the hay cutter fault.Therefore, how pan feeding roller mechanism and its transmission mechanism are carried out the key that appropriate design is raising hay cutter dependability, reduction hazard rate.
The utility model content
In order to solve the technology disadvantage that hay cutter transmission mechanism technology assembly precision is strict, cost is too high, the utility model provides the technical scheme of the careless device of a kind of efficient hand hay cutter, the major technique content of this technical scheme is: the composition of the transmission mechanism of the careless device of this efficient hand hay cutter comprises work spindle, steering gear and goes into the material roller transmission mechanism, by between the driving shaft of motor-operated work spindle and steering gear through the belt mechanism transmission, the driven shaft of steering gear drives through two of the material roller transmission mechanism of going into of gears engaged goes into the reverse material folding operation of material roller.
Second goal of the invention of the present utility model is to solve the hay cutter transmission mechanism and had both made the too much situation of feed quantity that occurs, this technical problem that also can avoid work spindle inertia force ground to destroy effectively, on the basis of above-mentioned overall technical architecture, the transmission between the driving shaft of its work spindle and steering gear is set to pulley transmission mechanism.
The careless device of efficient hand hay cutter that the utility model provides, steering gear separates setting with motor-operated work spindle, the driving-belt transmission mechanism of She Zhiing between the two, simplified its transmission arrangement, its manufacture process requirement also decreases, and be convenient to constitute and realize, thereby the hay cutter manufacturing cost is reduced greatly into material roller speed changing structure design with simple structure; Particularly its driving-belt transmission mechanism adopts belt gear to realize that the soft of pan feeding roller mechanism and work spindle is in transmission connection; when pan feeding roller mechanism feeding material too much can't remain in operation; the rapid increase of load; its belt gear is difficult to drive the driving shaft of steering gear and skidding occurs; present technique is utilized it to skid just and is cushioned the powerful transmission moment of inertia of work spindle; thereby reach the purpose of protection transmission mechanism; as long as in time reducing feeding or pushing strength with the aniseed grass just to make complete machine recover normal operating condition at once; thereby the setting of this transmission mechanism has overcome the technology disadvantage that pan feeding too much easily causes mechanical transmission component to damage effectively; so improved the reliability of the careless device work of this hand hay cutter greatly, the fault rate of hay cutter reduced significantly.
Description of drawings
Fig. 1 is the structural representation of the careless device transmission mechanism of existing hand hay cutter
Fig. 2 is that the structure of the careless device transmission mechanism of efficient hand hay cutter of the present utility model constitutes schematic diagram.
Embodiment
As shown in the figure in the example structure, the transmission mechanism that the utility model efficiently cuts up with a hay cutter careless device includes the work spindle 2 that is driven by electromotor 1 belt transmission, steering gear and go into the material roller transmission mechanism, be provided with the driving-belt transmission mechanism between the driving shaft 3 of work spindle 2 and steering gear, a kind of enforcement structure of this driving-belt transmission mechanism is sprocket wheel and chain drive, its another kind of formation of implementing is: respectively be provided with a between on the driving shaft 3 of work spindle 2 and steering gear and constitute bel-drivenn belt pulley 20,30, between the driving shaft 3 of steering gear and the driven shaft 4 by turning to bevel gear group 34,43 turn to engaged transmission, its bevel gear can be used bevel gear set, spiral bevel gear sets, also can be the hypoid bevel wheel group, two pan feeding roll shafts form counter-rotating through gears engaged, bring the travelling mechanism that forage enters the careless chamber of hand hay cutter into, driven shaft 4 and meshed transmission gear axle 5 drive it through Cardan shaft respectively and go into material roller 40,50.In the present embodiment, for realizing the optional gear ratio operation of pan feeding roller mechanism, the sprocket wheel or the belt pulley 20,30 that are arranged at respectively on the driving shaft 3 of work spindle 2 and steering gear are designed to tower shape drive, its tower shape drive is to be connect by the live-roller of finishing different drive ratios tower successively to constitute, and driving-belt is arranged on the live-roller of different drive ratios and just can realizes required gear ratio transmission.
