[0022] Please see Figures 1 to 5This utility model provides a technical solution: a bucket tooth structure for an excavator, including a bucket 1, a connector 2 inserted into the bottom of the bucket 1, a connecting rod 3 fixedly installed on one side of the connector 2, and a high-strength steel tooth 4 fixedly installed on one side of the connecting rod 3. The high-strength steel tooth 4 has a cavity inside, and an energy-absorbing component 5 is fixedly installed inside the cavity. Through the setting of the energy-absorbing component 5, a zinc-aluminum alloy layer 501 is set inside the high-strength steel tooth 4, which has good toughness. When the high-strength steel tooth 4 hits hard objects such as rocks, the zinc-aluminum alloy layer 501 will absorb and dissipate the impact energy through its own plastic deformation. The epoxy resin layer 502 has excellent viscoelasticity and can absorb vibration energy. The ceramic particle layer 503 supports the epoxy resin layer 502 and the zinc-aluminum alloy layer 501 while consuming the impact energy, avoiding deformation, thus achieving the effect of buffering and absorbing energy for the high-strength steel tooth 4 and improving the service life of the high-strength steel tooth 4. The bottom surface of the high-strength steel tooth 4 is fixedly provided with a reinforcing component 6, and both sides of the surface of the high-strength steel tooth 4 are fixedly provided with reinforcing ribs 7. Through the setting of reinforcing ribs 7 and reinforcing component 6, the reinforcing ribs 7 are used to improve the longitudinal strength of the high-strength steel tooth 4, and the transverse reinforcing ribs 601 and longitudinal reinforcing ribs 602 are used to improve the transverse and longitudinal structural strength of the high-strength steel tooth 4, so that the high-strength steel tooth 4 has higher strength, stronger pressure bearing capacity during digging, is not easy to deform, and has a long service life. A semi-screw 8 is fixedly installed on the bottom surface of the connecting rod 3. A locking component 9 is threadedly connected to the surface of the semi-screw 8. By setting the connector 2 and the locking component 9, the connector 2 is inserted into the insertion groove of the bucket 1. Three sets of limiting plates 10 fit the connecting rod 3, which facilitates the quick insertion and alignment of the connecting rod 3 and the bucket 1. At this time, the semi-screw 8 and the semi-screw 11 fit together. The anti-slip pad 902 is put in, and the locking nut 901 is turned to fix the connecting rod 3 to the bucket 1. After the bucket teeth are severely worn, only the bucket teeth need to be replaced, without replacing the entire bucket 1, which reduces costs.

[0023] The energy-absorbing component 5 includes a zinc-aluminum alloy layer 501, an epoxy resin layer 502, and a ceramic particle layer 503.

[0024] With the energy-absorbing component 5, the zinc-aluminum alloy layer 501 has good toughness. When the high-strength steel tooth 4 hits a rock or other hard object, the zinc-aluminum alloy layer 501 will absorb and dissipate the impact energy through its own plastic deformation. The epoxy resin layer 502 has excellent viscoelasticity and can absorb vibration energy. The ceramic particle layer 503 supports the epoxy resin layer 502 and the zinc-aluminum alloy layer 501 while consuming the impact energy, thus preventing deformation.

[0025] The reinforcing component 6 includes a horizontal reinforcing rib 601 and a longitudinal reinforcing rib 602. Both the horizontal reinforcing rib 601 and the longitudinal reinforcing rib 602 are fixedly installed on the bottom surface of the high-strength steel tooth 4. There are three sets of horizontal reinforcing ribs 601, and each set is fixedly connected to the longitudinal reinforcing rib 602.

[0026] By setting up the reinforcing component 6, the transverse reinforcing ribs 601 and longitudinal reinforcing ribs 602 are used to improve the transverse and longitudinal structural strength of the high-strength steel tooth 4, making the high-strength steel tooth 4 stronger.

[0027] The locking assembly 9 includes a locking nut 901 and an anti-slip washer 902. The anti-slip washer 902 is sleeved on the surface of the A semi-screw 8, and the locking nut 901 is threadedly connected to the surface of the A semi-screw 8.

[0033] The top surface of the connecting rod 3 has three sets of fitting grooves along the axial direction, which are adapted to the limiting piece 10.

[0034] The fitting groove serves to fit the limiting piece 10.

[0035] The number of high-strength steel teeth 4 is several, and the several high-strength steel teeth 4 are distributed at equal intervals along the axial direction.

[0037] Three sets of B-screws 11 are fixedly installed on the bottom surface of the bucket 1. The B-screws 11 are threadedly connected to the inside of the locking nut 901.

[0038] The B-screw 11 is designed to work in conjunction with the A-screw 8 to connect the bucket 1 and the connecting rod 3.

[0039] There are four sets of reinforcing ribs 7, which are symmetrically arranged on the surface of the high-strength steel tooth 4.

[0040] In this invention, the working steps of the device are as follows: First step: Insert the connector 2 into the insertion slot of the bucket 1. The three sets of limiting plates 10 fit against the connecting rod 3, which facilitates the quick insertion and alignment of the connecting rod 3 and the bucket 1. At this time, the A half screw 8 and the B half screw 11 fit against each other. Put on the anti-slip pad 902 and tighten the locking nut 901 to fix the connecting rod 3 to the bucket 1. After the bucket teeth are severely worn, only the bucket teeth need to be replaced, and the entire bucket 1 does not need to be replaced, which reduces costs. The second step: the reinforcing rib 7 is used to improve the longitudinal strength of the high-strength steel tooth 4, and the transverse reinforcing rib 601 and longitudinal reinforcing rib 602 are used to improve the transverse and longitudinal structural strength of the high-strength steel tooth 4, so that the high-strength steel tooth 4 has higher strength, stronger pressure bearing capacity during digging, is not easy to deform, and has a long service life. The third step: A zinc-aluminum alloy layer 501 is set inside the high-strength steel tooth 4, which has good toughness. When the high-strength steel tooth 4 impacts hard objects such as rocks, the zinc-aluminum alloy layer 501 absorbs and dissipates the impact energy through its own plastic deformation. The epoxy resin layer 502 has excellent viscoelasticity and can absorb vibration energy. The ceramic particle layer 503 supports the epoxy resin layer 502 and the zinc-aluminum alloy layer 501 while absorbing the impact energy, preventing deformation and buffering the high-strength steel tooth 4, thus improving its service life.
