Technical Field
[0001] The utility model relates to the technical field of bucket teeth, in particular to an anti-dropping bucket tooth component. Background Art
[0002] The bucket teeth of an excavator are important parts of the excavator. They are similar to human teeth and are also vulnerable parts. They are composed of a tooth seat and a tooth tip, which are connected by a pin. Since the tooth tip is the part that fails due to wear, you only need to replace the tooth tip.
[0003] The existing bucket tooth assembly of the excavator is subjected to a large impact strength during use, and the connecting pin between the tooth tip and the tooth seat is easy to loosen, so there is a risk that the pin will fall off from the pin hole, causing the tooth tip to fall off. For this reason, we propose an anti-fall-off bucket tooth assembly. Utility Model Content
[0004] The utility model aims to provide an anti-dropping bucket tooth assembly, which has the advantage of being able to prevent the pin shaft from falling off from the inside of the pin hole, thereby preventing the tooth tip from falling off from the tooth seat, and solves the problem that the existing excavator bucket tooth assembly is subjected to a large impact strength during use, and the connecting pin shaft between the tooth tip and the tooth seat is easy to loosen, so that there is a risk of the pin shaft falling off from the inside of the pin hole, thereby causing the tooth tip to fall off.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-dropping bucket tooth assembly, comprising a tooth seat, a tooth tip and a pin shaft, the upper surface of the tooth seat is provided with a protrusion, the lower surface of the tooth tip is provided with a slot, and the protrusion is located inside the slot, the protrusion and the outer surface of the tooth tip are both provided with pin holes, and the pin shaft is located inside the pin hole, and sliding grooves are symmetrically provided at both sides of the lower surface of the tooth tip, and slides are slidably installed inside the two slide grooves, and coil springs are fixedly connected to the upper surfaces of the two slides.
[0006] Preferably, insertion holes are symmetrically provided at both sides of the upper surface of the tooth seat, and the end of the slide plate away from the coil spring can be inserted into the insertion hole, thereby improving the compressive strength between the tooth tip and the tooth seat.
[0007] Preferably, a plurality of grooves are equidistantly arranged on the outer sides of the two slides, and the metal pick or the slot for a flat-blade screwdriver can be used to move the slides in a wave motion.
[0008] Preferably, fixing holes are symmetrically arranged on both sides of the outer surface of the tooth tip at positions above the pin hole, and a metal pick or a flat-blade screwdriver can be passed through the slot groove of the fixing hole to fix the skateboard.
[0009] Preferably, rounded corners are provided at both ends of the pin shaft and at the edge of the outer surface of the protruding portion, and the provision of the rounded corners facilitates the protruding portion to be inserted into the slot.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] 1. The utility model achieves the effect of preventing the pin shaft from falling off from the pin hole, thereby preventing the tooth tip from falling off from the tooth seat by arranging a tooth tip, a tooth seat, a slot, a protrusion, a pin hole, a pin shaft, a slide groove, a slide plate and a coil spring. The protrusion on the tooth seat is inserted into the slot of the tooth tip. The tooth tip and the pin hole on the tooth seat are on the same axis. The pin shaft is inserted into the pin hole. The elastic force of the coil spring causes the slide plate to move inside the slide groove, thereby blocking and fixing both ends of the pin shaft, preventing the pin shaft from falling off from the pin hole, and then preventing the tooth tip from falling off from the tooth seat.
[0012] 2. The utility model achieves the effect of facilitating the movement and fixation of the skateboard by setting the groove and the fixing hole, thereby facilitating the disassembly and assembly of the pin shaft. During the disassembly and assembly of the pin shaft, the skateboard needs to be moved away from the pin hole position, and the skateboard is moved by inserting a metal pick or a flat-blade screwdriver into the groove on the outer surface of the skateboard. The flat-blade screwdriver or the metal pick passes through the fixing hole and is inserted into the groove to fix the skateboard, thereby facilitating the disassembly and assembly of the pin shaft.
[0013] 3. The utility model provides an insertion hole so that the end of the slide plate away from the spiral spring can be inserted into the insertion hole, thereby improving the compressive strength between the tooth tip and the tooth seat. BRIEF DESCRIPTION OF THE DRAWINGS
