Description
Technical field
The utility model belongs to a kind of parts of graden machine, is specifically related to a kind of mechanism of beating the grass of mower.
Background technology
Mower is as a kind of portable graden machine, along with people to the consciousness of vegetation ecological and city trees and shrubs with require constantly to strengthen, use more and more widely with frequently.The mechanism of beating the grass is even more important as the cutter sweep of mower.Its structure directly affects operator's labour intensity and work quality, and the service life of the consumption of nylon rope and the mechanism self of beating the grass.
At present, both at home and abroad the employed mechanism of beating the grass of mower generally is divided into beat the grass two kinds of rope formulas of disposable beat the grass rope formula and storage.The utility model is for storing the rope formula of beating the grass.The employed storage in the current market rope formula mechanism of beating the grass of beating the grass, being connected with mower of having is pretty troublesome, the mechanism that needs will beat the grass earlier takes apart, with the moving head box with assemble the mechanism of beating the grass again after the mower output shaft is connected, use extremely inconvenience; It is by wiring seat and moving head box or the ratchet staggered orientation between the skull of beating the grass that rope is put in the mechanism that has, thereby allow the wiring seat rotate to realize, the gland outer end is pressed on the ground, the wiring seat is being pressed in the inner end, gland can rotate together along with the wiring seat, because gland and ground friction, resistance is very big, is easy to the situation that causes rope stretching not smooth; The mechanism's rope outlet that has is a blind hole, and nylon rope need penetrate from the hole, and is very inconvenient during assembling, and causes nylon rope coiling entanglement easily.
Summary of the invention
The purpose of this utility model is to provide a kind of novel, reliable and stable, mechanism of beating the grass of being convenient to the mower assembling and use.
The technical scheme that the utility model adopted is:
The mechanism of beating the grass of this mower, mainly by moving head box (1), place wiring seat (2) and spring (3) in the moving head box (1), be pressed in spring (3) and go up and place the gland (4) of moving head box (1), and be buckled in the skull of beating the grass (5) that is used to push down gland (4) on the moving head box (1) and constitute.
Moving head box (1) center is fixed with a metalwork, and left handed threaded hole (6) is arranged on the metalwork, need not take the mechanism of beating the grass apart, and direct and mower output shaft joins, and is convenient and swift.Two circle equally distributed boss (boss circle 10 and boss circle 12) are arranged on the inner cylinder face of wiring seat (2), and the number of every circle boss is at least 2, and the boss on the phase Lin Tutaiquan is not on the same warp; Have on gland (4) external cylindrical surface and be used for the equally distributed boss circle (11) that matches with wiring seat (2) boss.So, under the free state, wiring seat (2) can rotate an angle in moving head box (1), after external force is depressed gland (4), wiring seat (2) can be rotated further an angle along the rotation direction under the free state, after external force is unclamped, gland (4) free state of under spring (3) elastic force effect, rebounding.Gland (4) adopts a kind of ratchet to be connected (ratchet 13 and ratchet 14) with moving head box (1), under external force, can only slide up and down along the central axis direction of gland (4), but do not relatively rotate, only play the wiring seat (2) after single location turns an angle.Gland in the whole process (4) can not be expressed to wiring seat (2), only gets the positioning action when wiring seat (2) rotated, thereby is subjected to resistance when having avoided wiring seat (2) rotation fully and causes rope stretching not smooth.On moving head box (1) external cylindrical surface 2～10 rope outlets are arranged, rope outlet has breach (7) along the direction of moving head box (1) opening, is convenient to assembling and card rope.The position that the skull (5) of beating the grass is gone up the breach of corresponding moving head box (1) is provided with boss (8), prevents that nylon rope from leaping up out from rope outlet breach (7).

Embodiment
With reference to Fig. 1, shown in Figure 2, the wiring seat (2) that winds nylon rope is packed in the moving head box (1), because the rope outlet of moving head box (1) has breach, need not nylon rope is penetrated from the hole, directly nylon rope is snapped in the breach and get final product.In the chamber of moving head box (1), load onto spring (3) then, buckle gland (4) in spring (3) upper end subsequently, the skull (5) of will beating the grass at last is enclosed within on the gland (4), and be pressed to moving head box (1), beating the grass has boss on the skull (5), the rope outlet of just in time sealing moving head box (1) has breach, both is buckled together mutually gets final product.
During use, with the output shaft of the aligning of the left handed threaded hole (6) in the mechanism of beating the grass that assembles mower, directly stubborn consolidating gets final product on output shaft, need not take the mechanism of beating the grass apart.Behind the starting machine, the whole mechanism of beating the grass can rotate together along with the output shaft of mower.After preparation is beaten the grass before or rope shortens because of use consumes, on hardstand, knock earlier gland (4) downwards, gland (4) can move in mechanism, shown in figure (7), gland (4) the outer circumference surface boss (11) that originally is used for locating wiring seat (2) is also along with having left the circle of one on wiring seat (2) inner peripheral surface boss (10).Wiring seat (2) loses motive force like this, because inertia, wiring seat (2) rotating speed that slows down rotates with respect to moving head box (1) and gland (4).Nylon rope just begins to throw away from rope outlet like this, is glanded (4) outer circumference surface boss until wiring seat (2) and blocks; Behind gland (4) built on stilts, under the effect of spring (3), outwards upspring, outer circumference surface boss (11) is got back to boss circle (10) from boss circle (12) and is come up, same, wiring seat (2) loses motive force once more, because inertia, wiring seat (2) rotating speed that slows down rotates once more with respect to moving head box (1) and gland (4).Nylon rope continues to throw away from rope hole, blocks until being glanded (4) outer circumference surface boss.So circulation constitutes the rope stretching process.In the common device of beating the grass, gland is all being born the function that presses down the wiring seat, so be easy to be stuck after the gland that has is depressed, can't be returned to free state; The wiring seat location that has does not live, and rope stretching is more than, causes the nylon rope waste; The gland that has can rotate together along with the wiring seat, increases load easily, causes that rope stretching is not smooth.In the utility model, gland does not push the wiring seat, only plays single location wiring seat, can not cause resistance to it, guarantees that rope stretching is unimpeded and the location is timely and effective.
