Abstract
A novel overload protector of a corn harvester relates to an overload protector for agricultural machinery transmission. One end of a power input shaft is connected with a power wheel through a driving wheel, the other end of the power input shaft is meshed with a gear arranged on a power output shaft through a gear, and the power output shaft is fixed through a bearing. An output power chain wheel is fixed on the power output shaft through another bearing, an internal pressure disc is fixed at the outer end of the output power chain wheel, an external pressure disc is arranged outside the internal pressure disc, and the outer surface of the internal pressure disc and the inner surface of the external pressure disc are rough surfaces or are provided with friction teeth. The external pressure disc is fixed at the inner end of a spring shaft sleeve, a spring is fixed on the spring shaft sleeve, the outer end of the fixed spring is sealed by a spring seal plate, and an adjusting nut is arranged at the outer end of the spring seal plate. Furthermore, a double-connecting plate is arranged between the internal pressure disc and the external pressure disc, and the inner surface and the outer surface of the double connecting plate are both provided with friction teeth. The novel overload protector of the corn harvester has the advantages of capability of reducing damage of transmission components, especially gears in a transmission box caused by overload work and prolonging service life of equipment.
Description
Technical field
The utility model relates to agricultural machinery, is used in particular for the overload protective device of agricultural machinery transmissions such as grain header.
Background technology
Agricultural machinery relates to a large amount of transmission devices in operation process.The condition of work more complicated of harvesting corn particularly, often excess load operation, the time maize harvesting machine transmission system is arranged, the incident that the transmission case internal gear is damaged because of the overload transmission takes place.This has influenced the normal use of husker sheller on the one hand; Bring the certain economic loss to the user on the one hand.
Summary of the invention
The purpose of the utility model provides a kind of new type maize harvesting machine overload protective device, and it can reduce each parts of transmission, the particularly damage of transmission case internal gear that bring because of overload work, prolongs the service life of maize harvesting machine.
The purpose of the utility model realizes through following scheme:
A kind of new type maize harvesting machine overload protective device is characterized in that: an end of power input shaft connects power wheel through drive, and the other end is through the gear on the gears engaged power take-off, and power take-off passes through bearing fixing; Power take-off is through bearing fixing outputting power sprocket wheel, and the outer end of outputting power sprocket wheel is fixed with interior platen, and interior platen is outside equipped with external pressure plate; Interior platen and external pressure plate are discrete each other, and the outside of interior platen, the inner face of external pressure plate are matsurface or friction teeth is set that external pressure plate is fixed in the inner of spring axle sleeve; The spring axle sleeve can slide on power take-off; Spring shaft puts fixing spring, and the outer end of fixing spring is the capping of spring shrouding institute, is provided with adjusting nut in the outer end of spring shrouding; Through turning (pine or tight) adjusting nut, can reduce or increase the pressure of spring.
The utility model also can further be realized through following scheme:
Be provided with two fishplate bars, the two-sided friction teeth that all is provided with inside and outside two fishplate bars in described between platen and the external pressure plate.
Described friction teeth is center, radial convex and concave teeth with the axis hole.
Described friction teeth cross section is a triangle.
The beneficial effect of the utility model is: it can reduce each parts of transmission, the particularly damage of transmission case internal gear that bring because of overload work, prolongs the service life of maize harvesting machine.Can apply to other machinery.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is power input shaft, and 2 is power take-off, and 3 are ceding of Taiwan power chain, and 4 is interior platen, and 5 is external pressure plate, and 6 is spring, and 7 is adjusting nut, and 8 is bearing, and 9 is two fishplate bars, and 10 is the spring axle sleeve, and 11 is the spring shrouding.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, and make the above-mentioned purpose of the utility model, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the utility model done further detailed explanation.
Embodiment:
As shown in Figure 1, among the figure: an end of power input shaft 1 connects power wheel through drive, and the other end is through the gear on the gears engaged power take-off 2, and power take-off 2 is fixing through bearing 8; Power take-off 2 passes through fixedly ceding of Taiwan power chain 3 of bearing (not shown); The outer end of ceding of Taiwan power chain 3 is fixed with interior platen 4, and interior platen 4 is outside equipped with external pressure plate 5, is provided with two fishplate bars 9 between interior platen 4 and the external pressure plate 5; The inner face of the outside of interior platen 4, external pressure plate 5; And two fishplate bars 9 inside and outside the two-sided friction teeth 9 that all is provided with, friction teeth 9 for convex-concave alternate, be the radial triangle at center with the axle, increase friction when making engagement; External pressure plate 5 is fixed in the inner of spring axle sleeve 10; The spring axle sleeve can slide on power take-off 2; Fixing spring 6 on the spring axle sleeve 10, and the outer end of fixing spring 6 is 7 for 11 cappings of spring shrouding, is provided with adjusting nut 7 in the outer end of spring shrouding 11; Through turning (pine or tight) adjusting nut 7, can reduce or increase the pressure of spring.
When maize harvesting machine under excess load overload working condition, the required total output of the ceding of Taiwan strengthens, and is passed to overload protective device; When the pressure that the protector spring is produced acquired a certain degree, platen 4 rotated in the frictional force that interior platen 4 and external pressure plate 5 and two fishplate bar are 9 was not enough to drive, like this; The internal mutually platen 4 of external pressure plate 5 skids; Can't drive ceding of Taiwan power chain 3, the particularly effect of internal gear of protection each parts of transmission case is considered in power take-off 2 idle running.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
