Description

Technical Field

[0001] The present application relates to the technical field of excavator bucket accessories, and more specifically to a wear-resistant and durable bucket tooth guard. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig soil, coal, rocks and other materials above or below the bearing surface, and loads them into transport vehicles or unloads them to stockpiles. A bucket tooth guard refers to an accessory installed on the bucket to protect the bucket during excavation.

[0003] The patent document (CN218204622U) discloses a wear-resistant mining bucket for an excavator, comprising two side plates, wherein a group of protective plates are connected to the front sides of the two side plates, wherein the protective plates are U-shaped and buckled on the side plates, and the protective plates are fixedly connected to the side plates by bolts. The protective plates directly collide with the ore during operation, and the frequency of maintenance and replacement is high. The side of the protective plate away from the side plate has two inclined surfaces and a plane located between the two inclined surfaces, and a cross-section of the side of the protective plate away from the side plate is trapezoidal. When the inclined surface of the protective plate collides with the rock, the contact force is decomposed into a horizontal force and a vertical force, and the rock is easily slid down along the inclined surface, thereby reducing the risk of forming larger pits on the inclined surface. However, in the length direction of the protective plate, the inclined surface is a plane, that is, the projection of the inclined surface along the length direction of the protective plate is overlapped. If the rock is tilted at a predetermined angle and its contact surface is parallel to the inclined surface, the force cannot be decomposed at this time, and pits are easily formed on the inclined surface.

[0004] Therefore, there is a demand for providing a wear-resistant and durable bucket tooth guard that can decompose the impact force at more angles. Summary of the invention

[0027] Schematic wear-resistant and durable bucket tooth guard,

[0028] refer to Figures 1 to 3 According to a preferred embodiment of the utility model, a wear-resistant and durable bucket tooth guard is fixedly installed on the side plate of the bucket tooth of the excavator. The wear-resistant and durable bucket tooth guard includes a connecting seat 10 and a contact piece 20.

[0029] Specifically, Figure 1 As shown, one end of the connecting seat 10 is fixedly mounted on the side plate, the contact member 20 is fixedly connected to the end of the connecting seat 10 away from the side plate, and the end of the contact member 20 away from the connecting seat 10 has an arc surface 201 and a plurality of ball head columns 202, and the ball head columns 202 are arranged in sequence along the length direction of the arc surface 201.

[0030] It should be noted that the length of the arc surface 201 is equal to the sum of the ball diameters of all the ball head columns 202, and the width of the arc surface 201 is equal to the ball diameter of one of the ball head columns 202. In the embodiment of the present application, the number of the ball head columns 202 is five, and the overall length of the five ball head columns 202 arranged in an arrangement is the same as the length of the arc surface 201; it should also be noted that each of the ball head columns 202 includes a hemispherical head 2021 and a pseudo-cylindrical portion 2022, the hemispherical head 2021 is located at the top of the pseudo-cylindrical portion 2022, and the end of the pseudo-cylindrical portion 2022 facing away from the hemispherical head 2021 extends into the arc surface 201.

[0031] It should also be noted that after the wear-resistant and durable bucket tooth guard is installed on the side plate, the ball head column 202 is located at the top of the side plate. Since the hemispherical head 2021 on the ball head column 202 is a spherical surface, when the bucket excavates external rocks and the external rocks collide with any position of the ball head column 202, the collision force will be decomposed into a horizontal force and a vertical force, and guide the external rocks to slide along the spherical surface of the hemispherical head 2021 to the arc surface 201, and further slide along the arc surface 201, or slide from the arc surface 201 to the side curved surface of the imitation cylindrical part 2022 and finally slide out. It is obvious that compared with the two inclined surfaces in the prior art, the embodiment of the present application has the advantage of providing more angles to decompose the collision force, which helps to reduce the number of pits generated by the collision, thereby achieving the technical purpose of wear resistance and durability.

[0032] Furthermore, when external rocks slide from the arc surface 201 into or outside the bucket, in order to avoid collision with the connecting seat 10 , the width of the connecting seat 10 is equal to the width of the contact member 20 .

[0033] Furthermore, in order to realize the detachable connection between the contact member 20 and the connection base 10, as Figure 2 As shown, the end of the connecting seat 10 away from the side plate has a plurality of protrusions 101, and a cross-section of the protrusion 101 is trapezoidal. The end of the contact member 20 close to the connecting seat 10 has a plurality of grooves 203, and a cross-section of each of the grooves 203 is trapezoidal. The side wall of each protrusion 101 has a first threaded hole 1011, and the side wall of each of the grooves 203 has a second threaded hole 2031. The protrusions 101 correspond to the grooves 203 one by one, and each of the protrusions 101 extends into the corresponding groove 203, and the first threaded hole 1011 is directly opposite to the second threaded hole 2031.

[0034] It should be noted that by making the contact piece 20 detachably connected to the connecting base 10, the durability of the connecting base 10 is ensured; in addition, by opening the first threaded hole 1011 and the second threaded hole 2031 on the side walls of the protrusion 101 and the groove 203, the external bolts are screwed into the first threaded hole 1011 and the second threaded hole 2031 from both ends of the connecting base 10, thereby further ensuring that the side of the connecting base 10 close to the contact piece 20 is equal to the width of the contact piece 20; in addition, since the cross-sections of the protrusion 101 and the groove 203 are both trapezoidal, it is convenient for the contact piece 20 to be placed on the connecting base 10 from above.

[0035] Furthermore, in order to realize the connection between the connecting seat 10 and the side plate, as Figure 1 and Figure 2 As shown, the end of the connecting seat 10 facing away from the contact piece 20 has an extension groove 102 with an opening, and the two side walls of the extension groove 102 have a plurality of through third threaded holes 1021. External bolts can be screwed into the third threaded holes 1021 and the threaded holes on the side plate to achieve the connection between the connecting seat 10 and the side plate.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, the bottom of the extending groove 102 has a receiving hole 1022, the receiving hole 1022 is connected to the extending groove 102, and a shock absorbing member 30 is disposed in the receiving hole 1022. More specifically, the shock absorbing member 30 is a rubber pad.

[0037] It should be noted that, by providing the shock absorbing member 30 , a part of the vibration transmitted from the contact member 20 is absorbed, thereby reducing the force on the bolt in the third threaded hole 1021 , which helps to reduce the risk of deformation of the bolt in the third threaded hole 1021 .

[0038] Furthermore, in order to facilitate placing the rubber pad into the receiving hole 1022 , a pulling member 40 is provided at one end of the rubber pad.

[0039] More specifically, one end of the shock absorbing member 30 has a through hole (not shown in the figure), and the pulling member 40 is a steel wire rope, one end of which passes through the through hole and is fixedly connected to the body of the steel wire rope to form a ring structure (not shown in the figure).

[0040] It should be noted that, during installation, one end of the rubber pad provided with the steel wire rope is first placed into the receiving hole 1022 , and then the rubber pad can be dragged into the receiving hole 1022 by pulling the steel wire rope.

[0041] Furthermore, when the rubber pad moves to a predetermined position in the receiving hole 1022, the steel wire rope is hidden inside. Figure 3 As shown, the shock absorbing member 30 has a wire embedding groove 301 on both sides of the through hole, and the end of the steel wire rope away from the annular structure is placed in the wire embedding groove 301 or detached from the wire embedding groove 301 .

[0042] It should be noted that when the rubber pad is pulled, the end of the steel wire rope that is away from the annular structure is detached from the cable burying groove 301 and the steel wire rope is pulled. After the rubber pad moves to a predetermined position, the steel wire rope is bent again and placed in the cable burying groove 301.

[0043] Furthermore, in order to facilitate the removal of the steel wire rope placed in the buried wire groove 301, Figure 3 As shown, one end of the buried cable groove 301 has an expanded hole portion 302 , the width of the expanded hole portion 302 is greater than the width of the other end of the buried cable groove 301 , and one end of the steel wire rope away from the annular structure extends into the expanded hole portion 302 .

[0044] In summary, the wear-resistant and durable bucket tooth guard plate based on the embodiment of the present application is explained, which provides the wear-resistant and durable bucket tooth guard plate with advantages such as more angle-decomposable collision force.

[0045] It is worth mentioning that in the embodiment of the present application, the wear-resistant and durable bucket tooth guard has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the wear-resistant and durable bucket tooth guard provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0046] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
