Interchangeable device for bucket and hammer of small excavator is a job that needs to be done frequently, sometimes it is exchanged two or three times a week, and the two axle pins connected to the cantilever must be removed before each work. In the past, the hammer or bucket was slowly removed from the connector by hitting the axle pin with a manual sledgehammer. Its sledgehammer knocking disassembly method is not only difficult to operate, but also time-consuming, labor-intensive and very unsafe. The labor intensity is high and the operation is highly dangerous. The interchangeable disassembly device for bucket and hammer of small excavator produced by our factory makes the disassembly of bucket and hammer simple and convenient, safe and reliable, and achieves the purpose of saving time and labor.
The interchangeable disassembly device for the bucket and hammer of a small excavator comprises a pin sleeve arranged on the body of the small excavator, and the pin sleeve is provided with two transverse holes, and the two transverse holes of the interchangeable disassembly device are respectively connected with two body connecting parts, and the two body connecting parts are respectively connected with two pull rods, and the two pull rods are connected with a crossbeam, and the crossbeam is threadedly connected with a lead screw, and the bottom end of the lead screw is abutted with a protective pad, and the top end of the lead screw is provided with a square four-cornered body cap, and the body connecting part is provided with a transverse shaft and a vertical hole, and the transverse shaft is matched and connected with the transverse hole on the pin sleeve, and the center of the crossbeam is provided with an inner screw hole, and the inner screw hole is threadedly connected with the lead screw, and longitudinal jacks are provided on both sides of the crossbeam, and the pull rod passes through the vertical hole on the body connecting part and the longitudinal jack on the crossbeam and is threadedly connected with the nut.
The upper surface of the protective pad of the interchangeable disassembly device for the bucket and hammer of the small excavator is provided with a circular groove abutting with the bottom end of the lead screw, and the lower surface of the protective pad is provided with a limit groove, and its limit groove is connected with the top of the pin shaft on the body of the small excavator.
The advantages of this small excavator bucket and hammer interchangeable disassembly device are: the disassembly device is fixed by utilizing the transverse holes of the original parts on the small excavator body, and the pin shaft to be disassembled is slowly pushed out according to the lever principle, thereby reducing and avoiding damage to the pin and the shaft hole and the labor intensity and working time of the workers, improving the maintenance work efficiency, improving the safety and stability of maintenance and job-site operation pin replacement, and effectively ensuring the safe operation of on-site operations.
