Abstract
An accessory quick-change mechanism for a loader comprises a quick-change bracket, a quick-change handle, a screw rod, a hinge pin, a spring, a lower spring seat, a lock pin and an upper spring seat. The quick-change bracket is inserted into an accessory of the loader with a long hole, to cause three surfaces of the quick-change bracket to be tightly clung to the three corresponding surfaces of the accessory of the loader; the upper end of the quick-change handle is hinged at the upper and the lower ends of the quick-change bracket through a cylindrical pin, is connected with the screw rod through a hinge pin, and is pressed on the upper spring seat; the screw rod is connected with the lower spring seat after penetrating through the spring; and the lower spring seat is hinged with the lock pin through an elastic pin. The utility model solves the problem of difficult assembly of an accessory to be assembled on a loader, can facilitate the accessory to be quickly and conveniently articulated with the main machine, greatly reduces the work intensity and time in changing the accessory, and obviously enhances the work efficiency. The mechanism ensures a safer and more reliable connection between the accessory and the main machine, and enhances the safety of the accessory during working.
Description
Technical field
The utility model belongs to the loader field, relates to a kind of loader attachment quick-changing mechanism.
Background technology
In the loader practical operation, in order to realize the quick connection of various annexes (such as scraper bowl, armful folder, quartering hammer etc.) on loader, quick-changing mechanism often need be installed on loader, to reduce the workload of changing annex, increase work efficiency.At present, a kind of quick-changing mechanism of coupling type is installed on domestic some loader, going up of annex is articulated on the top rail of quick-changing mechanism, and the following hinge pin of quick-changing mechanism outwards moves by manual or hydraulic operation, passes the following hinge hole of annex, finishes connection.It is more convenient that the going up of this quick-changing mechanism articulates, but hinge pin needs complete mating holes could insert down, difficult grasp, and this mechanism to process, welding precision requires than higher.
The utility model content
The purpose of this utility model is to provide a kind of loader attachment quick-changing mechanism relatively simple for structure, easy to use and reliable, cheap for manufacturing cost.
The technical solution of the utility model is: the loader attachment quick-changing mechanism mainly comprises quick change support, quick change handle, screw rod, hinge pin, spring, spring lower seat, lock pin, the spring seat of honour.The insertion of quick change support is had in the loader attachment of slotted hole H, three faces of M, N, P of quick change support and corresponding three faces of loader attachment are adjacent to; Quick change handle upper end is hinged on quick change support lower end by straight pin and links to each other with screw rod by hinge pin, and is pressed on the spring seat of honour; Screw rod passes spring and links to each other with spring lower seat; Spring lower seat is hinged by resilient key and lock pin.
The tapered end of lock pin bottom is inserted among the slotted hole H of loader attachment.
The utility model can reach following beneficial effect:
Solved the equipped annex of loader difficult problem has been installed.Can make annex realize articulating with main frame fast and easily, and significantly reduce working strength and the time of changing annex, significantly improve operating efficiency.And this mechanism makes annex more safe and reliable with being connected of main frame, improved annex safety in the course of the work.
Description of drawings
Fig. 1 is the structure chart of the utility model loader attachment quick-changing mechanism impaction state.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the structure chart of the utility model loader attachment quick-changing mechanism releasing orientation.
The specific embodiment
As shown in Figure 1, the loader attachment quick-changing mechanism mainly comprises quick change support 1, quick change handle 2, screw rod 3, hinge pin 4, spring 5, spring lower seat 6, lock pin 7, the spring seat of honour 9.1 insertion of quick change support is had in the loader attachment 8 of slotted hole H, three faces of M, N, P of quick change support 1 and loader attachment 8 corresponding three faces are adjacent to; Quick change handle 2 upper ends are hinged on the quick change support by straight pin, and the lower end links to each other with screw rod 3 by hinge pin 4, and is pressed on the spring seat of honour 9; Screw rod 3 passes spring 5 and links to each other with spring lower seat 6; Spring lower seat 6 is hinged by resilient key and lock pin 7; Lock pin 7 inserts among the slotted hole H of annex 8.Because the inclined-plane W of lock pin 7 and contacting of slotted hole H have the trend that M, N, P three faces are adjacent to more under the effect of spring force.
Can find out that from Fig. 1 and Fig. 3 when the pull-up quick change handle 2, quick change handle 2 move together by hinge pin 4 drivening rods 3, connecting rod 3 moves up by spring lower seat 6 drive lock pins 7; Meanwhile the relative distance of the spring seat of honour 9 and spring lower seat 6 strengthens and makes the degree that compresses of spring 5 reduce gradually, reduces gradually for lock pin 7 downward pressure, for motion, the lock pin 7 of quick change handle 2 and play separating of annex 8 and quicken and the effect of power-assisted; When lock pin 7 and annex 8 broke away from fully, the stopping means on the quick change support 1 was limited to current location to quick change handle 2 and no longer moves, and so just can remove annex 8 from quick-changing mechanism.Behind the accessory replacing, press down quick change handle 2, make lock pin 7 move downward, the degree that compresses of spring 5 strengthens simultaneously; When quick change handle 2 compressed fully, the stopping means on the quick change support 1 was limited to current location to quick change handle 2 and no longer moves; This moment, hinge pin 4 was crossed the dead point, the trend that the elastic force of spring 5 has makes that quick change handle 2 continues to press down, lock pin 7 and annex 8 compress more.The difficult problem of assembling when adopting this mechanism to improve loader attachment effectively to change, the safety and the degree of reliability on having increased annex and main frame being connected, feasible replacing annex becomes convenient, quick.
