Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Consult shown in Fig. 1, a kind of seedling case seedling sending detent mechanism, including seedling box bracket 1 and the seedling sending axle 2 being assemblied in seedling box bracket 1 bottom, it is arranged on the seedling sending wheel 3 on seedling sending axle 2, also includes seedling sending ratchet 4 and be arranged on the detent mechanism 5 outside seedling box bracket 1.
On the top of seedling box bracket 1 equipped with sprocket wheel 6, sprocket wheel 6 is arranged on seedling box bracket 1 by sprocket shaft, sprocket wheel 6 is in transmission connection by chain 7 with seedling sending wheel 3, and seedling sending wheel 3 is positioned at inside seedling box bracket 1 with sprocket wheel 6 transmission combination, forms stable seedling sending transmission process.
As shown in Figure 2, detent mechanism 5 includes positioning seat 51, location dish 52, locating detent 53 and ratchet 54, specifically, positioning seat 51 is fixedly mounted on outside seedling box bracket 1, locating detent 53 is arranged on positioning seat 51 by bearing pin, seedling sending ratchet 4 and location dish 52 are coaxially mounted on seedling sending axle 2, and location dish 52 is positioned at outside seedling sending ratchet 4, simultaneously, location dish 52 is socketed pawl base 55, such pawl base 55 can make rotary oscillation on location dish 52, pawl base 55 one end is connected with ratchet push rod 56, pawl base 55 other end is installed ratchet 54, ratchet 54 and seedling sending ratchet 4 cooperate assembling.
In the present embodiment, location dish 52 is fixed with seedling sending axle 2 by the mode of hexagonal hole or key connecting, location dish 52 is along the circumferential direction uniformly provided with some location flank of tooth 521, locating detent 53 is provided with locating surface 531 and the parting surface 532 of angled layout, and locating surface 531 and the location flank of tooth 521 are in snap-fit or disengaged position.
Meanwhile, being provided with locating detent out of stock 9 at positioning seat 51 away from one end of ratchet 54, the parting surface 532 of locating detent out of stock 9 and locating detent 53 is in compressing or disengaged position.
And, ratchet 54 connects a torsion spring 8, ratchet 54 is fitted with seedling sending ratchet 4 flank of tooth by torsion spring 8 with seedling sending ratchet 4, torsion spring 8 other end is connected with pawl base 55, the reset of ratchet 54 can be realized by torsion spring 8, keep the mated condition between ratchet 54 and seedling sending ratchet 4, it is achieved the interval stepping process of seedling sending. Locating detent 53 connects an extension spring 10, and extension spring 10 other end is connected with positioning seat 51, it is possible to achieve the reset of locating detent 53 connects.
Operation principle of the present utility model and work process be:
As shown in Figure 3, when ratchet push rod 56 promotes ratchet 54 to drive seedling sending ratchet 4 to rotate along clockwise direction, seedling sending ratchet 4 drives seedling sending axle 2 to rotate, the location flank of tooth 521 of location dish 52 is close to by locating detent 53 under the effect of extension spring, when ratchet 54 promotes seedling sending ratchet 4 to move to the upper extreme position shown in Fig. 3, now, the locating surface 531 of locating detent 53 is just fitted with the location flank of tooth 521, it is possible to achieve the location completely of seedling sending axle 2.
After ratchet 54 reaches upper extreme position, under the effect of ratchet push rod 56, ratchet 54 and pawl base 55 1 act as return and swing back motion, when return swings to certain angle, locating detent out of stock 9 on positioning seat 51 touches the parting surface 532 of locating detent 53, under the pressure effect of locating detent out of stock 9, the parting surface 532 of locating detent 53 is completely disengaged with the location flank of tooth 521, advances rotation to get ready clockwise for next ratchet 54.
When ratchet 54 moves to lower position as shown in Figure 4, locating detent 53 is completely disengaged with location dish 52 and has certain safe distance, it is to avoid during next circulation, and locating detent 53 does not disengage with location dish 52, damages seedling sending ratchet 4 and ratchet 54.
The above embodiments are only preferred embodiment of the present utility model, it is impossible to limit interest field of the present utility model with this, therefore, according to the equivalent variations that this utility model claim is made, still belong to the scope that this utility model is contained.
