Abstract
A soybean swather overload protective device used in an agricultural machine solves the problem that: the soybean swather can be damaged by hard articles and overload under the operating state. The utility model is composed of a connecting shaft, a round nut and a flat pad for adjusting the tension of an overload spring, the overload spring, a clutch claw A, a clutch claw B, and a steel ball, a lining, a distance sleeve and a square hole sleeve connected with the claw B through a screw thread in the clutch claw A. The clutch claw A is in bonding state with the clutch claw B under the effect of the tension of the overload spring. The arrangement and application of the utility model can effectively prevent the soybean swather from being damaged by the overload, and the utility model is also the future developing direction of the swather.
Description
Technical field:
The utility model is in the agricultural machinery, and the soybean swather in use plays the not impaired a kind of overload protection arrangement of protection swather owing to running into hard thing or overload.
Background technology:
At present, known soybean swather does not in use have overload protection arrangement, because ground condition difference makes hard thing such as finger stone, tree root etc. block blade easily, and transmission be hard the connection, very easily makes the swather damage, causes unnecessary loss to the peasant.
Summary of the invention:
The purpose of this utility model: in order to overcome this type of problem that existing soybean swather exists, the utility model provides a kind of soybean swather overload protection arrangement, and this device can prevent effectively owing to transship the loss that causes.
The utility model is that the technical scheme that its technical problem of solution is adopted is: connecting axle is connected with clutch pawl A by flat key, one end of square hole cover links to each other with another clutch pawl B with screw thread, round nut, plain cushion and overload spring are housed on the connecting axle, connecting axle drives clutch pawl A by flat key and rotates, one end of square hole cover links to each other with another clutch pawl B with screw thread, two clutch pawls are meshed by tooth power are delivered to the square hole cover from connecting axle, regulate the frictional force size of two clutch pawl contact-making surfaces by overload spring, make complete machine reach desired torsion and do not throw off operate as normal.When running into hard thing, when required torsion surpassed normal forces, clutch pawl contact-making surface skidded and has stoped the transmission of power, had reached the purpose that prevents that machine from damaging owing to overload.When hard thing or overload eliminating, under the effect of overload spring tension force, two clutch pawl combinations again, transferring power is recovered the normal operation of soybean swather.
The beneficial effects of the utility model are: the protection machine, and avoid machine in use, owing to running into the damage that barrier or overload cause.
Description of drawings:
Figure is the overload protection arrangement structural representation of soybean swather.
Piece number explanation among the figure: 1, connecting axle, 2, round nut, 3, plain cushion, 4, overload spring, 5, clutch pawl A, 6, flat key, 7, the square hole cover, 8, lining, 9, steel ball, 10, spacer sleeve, 11, clutch pawl B.
Embodiment:
At first power passes to connecting axle (1), and by flat key (6) drive clutch pawl A (5) rotation, clutch pawl A (5) is meshed by tooth with clutch pawl B (11) and the steel ball (9) that is used for reducing friction is housed between clutch pawl B (11) and connecting axle (1), spacer sleeve (10) and lining (8), overload spring (4) is the adjusting that realizes frictional force size between clutch pawl A (5) and clutch pawl B (11) by the adjusting of round nut (2) and plain cushion (3), by regulating the size of frictional force, determine required cutting force and overload power, clutch pawl B (11) is rotated synchronously with clutch pawl A (5), and clutch pawl B (11) is integral by thread connection with square hole cover (7), power just passes to square hole cover (7) by connecting axle (1) like this, and the square hole cover continues transmission downwards with power again and finishes normal operation.When overload power increased, clutch pawl A (5) produced relative slip with clutch pawl B (11), cuts off power, reached the purpose that the protection swather does not damage because of overload.When hard thing or overload eliminating, under the effect of overload spring tension force, two clutch pawl combinations again, transferring power is recovered the normal operation of soybean swather.
Claims (2)
1. soybean swather overload protection arrangement; it is characterized in that: connecting axle (1) is connected with clutch pawl A (5) by flat key (6); one end of square hole cover (7) links to each other with another clutch pawl B (11) with screw thread, and round nut (2), plain cushion (3) and overload spring are housed on the connecting axle (1).
2. soybean swather overload protection arrangement according to claim 1 is characterized in that: the steel ball (9), spacer sleeve (10) and the lining (8) that are used for reducing friction are housed between connecting axle (1) and the clutch pawl A (5).
