Description

Technical Field

[0001] This utility model relates to the field of mechanical grab bucket technology, specifically a mechanical grab bucket with the function of reducing wear on bucket teeth. Background Technology

[0002] A grab bucket is a closable bucket designed to grab mud, sand, and various bulk goods. It is a lifting device that mainly relies on the opening and closing of two combined buckets or multiple jaw plates to grab and unload bulk materials. Chinese Patent No. CN202322626826.6 discloses a leak-proof mechanical grab bucket, which includes two symmetrically arranged grab buckets. Each grab bucket has a U-shaped groove formed at its opening edge, and a sealing component is installed within the U-shaped groove. The sealing component includes a U-shaped seat disposed within the U-shaped groove and a U-shaped docking frame connected to the U-shaped seat by a spring. The U-shaped docking frame extends at least partially out of the U-shaped groove. This design solves the problem in existing grab buckets where, when grabbing small items, the items easily enter the sealing groove, causing blockage and affecting the sealing effect and the closure of the grab bucket.

[0003] Based on the above, the inventors have discovered the following problems: The above-mentioned grab bucket solves the problem in the prior art where, when grabbing some small-sized goods, the goods easily enter the sealing groove, causing blockage of the sealing groove and affecting the sealing effect and the closure of the bucket body. However, it ignores the problem that the bucket teeth themselves, due to the wear and tear of their connecting parts during use, result in uneven contact surfaces between them and other parts of the grab bucket. This causes the bucket teeth to shake during operation, and the shaking causes the bucket teeth to continuously rub irregularly against the material during the grabbing process, increasing the number and intensity of friction. This makes the surface of the bucket teeth more prone to wear, affecting the service life of the bucket teeth. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mechanical grab bucket with the function of reducing bucket tooth wear, comprising a bucket body, a connecting plate, and a fixing component. The bucket body is provided with a connecting plate, the connecting plate is connected to a plurality of connecting heads, the connecting heads are provided with a fixing component, the fixing component is connected to a bucket tooth block, and the bucket tooth block has mounting holes on both sides.

[0005] Furthermore, the fixing component includes a through hole, the connector has a through hole, the through hole has a movable cavity, the movable cavity has a pair of movable holes at both the upper and lower ends, the movable hole has a pad, the pad has a limiting block on both sides, the movable hole has a limiting groove on both sides, and the limiting block is movably disposed in the limiting groove.

[0006] Furthermore, the movable cavity is provided with a pressing component, the pressing component has a connecting hole, there are locking blocks on both sides of the connecting hole, and a rotating cylinder is provided in the connecting hole. There are locking grooves on both sides of the outer wall of the rotating cylinder, and the locking blocks are engaged with the locking grooves.

[0007] Furthermore, both ends of the rotating cylinder extend out of the connector and connect to the mounting hole, and a fixing hole is provided inside the rotating cylinder, and a fixing shaft is provided inside the fixing hole.

[0008] Furthermore, the fixing hole is interference-fitted with the fixing shaft.

[0009] Furthermore, one end of the pad is attached to the side of the extrusion piece, and the other end of the pad extends out of the movable hole and is provided with a rubber pad.

[0010] Furthermore, the thickness of the outer wall of the extruded component in the horizontal direction is greater than its thickness in the vertical direction.

[0011] Furthermore, reinforcing blocks are provided on both sides of the connector, and the reinforcing blocks are connected to the side of the connector plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this mechanical grab bucket with the function of reducing bucket tooth wear is reasonable and has the following advantages: The design of the fixing components ensures a tight connection between the connector and the bucket tooth block. When the connector wears down over time, causing loosening of the connection with the tooth block, rotating the extrusion component, along with the pad and rubber pad, adjusts the rubber pad to maintain a tight fit with the inner wall of the bucket tooth block. This ensures the connector remains firmly installed with the tooth block, preventing wobbling during operation. Since wobbling causes friction between the bucket tooth block and the material during gripping, reducing wobbling reduces wear. Furthermore, the interference fit between the fixing shaft and the fixing hole firmly secures the bucket tooth block and the connector, limiting the rotation of the extrusion component and preventing loosening of the pad and the inner wall of the bucket tooth block, thus ensuring a stable connection between the bucket tooth block and the connector.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 The present invention provides a technical solution as follows: Example: In this embodiment, a mechanical grab bucket with the function of reducing bucket tooth wear includes a bucket body 1, a connecting plate 2, and a fixing component. The bucket body 1 is provided with the connecting plate 2, and the connecting plate 2 is connected to a plurality of connecting heads 3. The connecting heads 3 are provided with a fixing component, and the fixing component is connected to a bucket tooth block 4. The bucket tooth block 4 has mounting holes 6 on both sides.

[0017] The fixing component includes a through hole 9. The connector 3 has a through hole 9 and a movable cavity 12. The movable cavity 12 has a pair of movable holes 15 at both the upper and lower ends. A pad 10 is provided in the movable hole 15. Limiting blocks 16 are provided on both sides of the pad 10. Limiting grooves 17 are provided on both sides of the inner wall of the movable hole 15. The limiting blocks 16 are movably disposed in the limiting grooves 17. By designing the limiting block 16 and the limiting groove 17, the pad 10 can be movably positioned within the movable hole 15 without detaching from the movable hole 15, thus ensuring the integrity of the device.

[0018] The movable cavity 12 is provided with a pressing component 13, and a connecting hole 19 is provided in the pressing component 13. A locking block 14 is provided on both sides of the connecting hole 19, and a rotating cylinder 8 is provided in the connecting hole 19. A locking groove 11 is provided on both sides of the outer wall of the rotating cylinder 8, and the locking block 14 is engaged with the locking groove 11.

[0019] Wherein, the two ends of the rotating cylinder 8 extend out of the connecting head 3 and are connected to the mounting hole 6, the rotating cylinder 8 is provided with a fixing hole 20, and a fixing shaft 7 is provided in the fixing hole 20; The bucket tooth block 4 is fitted onto the connecting head 3, and then the rotating cylinder 8 is passed through the mounting hole 6, the through hole 9 and the connecting hole 19 to initially connect the bucket tooth block 4 and the connecting head 3. Rotating the rotating cylinder 8, with the cooperation of the locking block 14 and the locking groove 11, can drive the extrusion part 13 to rotate, thereby pushing the pad block 10 toward the inner wall of the bucket tooth block 4. When the pad block 10 is tightly attached to the inner wall of the bucket tooth block 4, the fixing shaft 7 is inserted into the fixing hole 20, thereby firmly fixing the connecting head 3 and the bucket tooth block 4.

[0020] The fixing hole 20 is interference-fitted with the fixing shaft 7; By using the interference fit design between the fixed shaft 7 and the fixed hole 20, the fixed hole 20 can be enlarged, and the outer diameter of the rotating cylinder 8 can be increased. This allows the rotating cylinder 8 to be firmly fixed to the mounting hole 6 and the connecting hole 19, thereby firmly installing the bucket tooth block 4 and the connecting head 3. Furthermore, with the cooperation of the pad block 10, the extruder 13 and the rotating cylinder 8, the rotation of the extruder 13 is limited, preventing the rotation of the extruder 13 from causing the connection between the pad block 10 and the inner wall of the bucket tooth block 4 to loosen.

[0021] One end of the pad 10 is attached to the side of the extrusion piece 13, and the other end of the pad 10 extends out of the movable hole 15 and is provided with a rubber pad 18. The design of the rubber pad 18 can increase the friction between the inner wall of the bucket tooth block 4 and the connecting head 3, thus strengthening the connection between the bucket tooth block 4 and the connecting head 3.

[0022] Wherein, the thickness of the outer wall of the extruder 13 in the horizontal direction is greater than the thickness in the vertical direction; By using the extrusion member 13, rotating the extrusion member 13 can push the pad 10 to move within the movable hole 15, adjusting the size of the pad 10 extending beyond the connecting head 3. When the bucket tooth block 4 is fitted with the connecting head 3, the pad 10 can be adjusted to fit tightly against the inner wall of the bucket tooth block 4, thereby strengthening the connection between the bucket tooth block 4 and the connecting head 3, preventing the bucket tooth block 4 from shaking. Furthermore, the adjustment of the pad 10 can be adjusted according to different models of bucket tooth blocks 4, making this device have a wide range of applications.

[0023] The connector 3 is provided with reinforcing blocks 5 on both sides, and the reinforcing blocks 5 are connected to the side of the connector plate 2. The design of the reinforcing block 5 can strengthen the connection between the connecting head 3 and the connecting plate 2, ensuring the stability of the bucket tooth block 4, thereby preventing the bucket tooth block 4 from shaking during use and increasing the wear of the bucket tooth block 4.

[0024] Working principle: In use, the bucket tooth block 4 is fitted onto the connecting head 3, and then the rotating cylinder 8 is passed through the mounting hole 6, through hole 9, and connecting hole 19 to initially connect the bucket tooth block 4 and the connecting head 3. Rotating the rotating cylinder 8, with the cooperation of the locking block 14 and the locking groove 11, can drive the extrusion part 13 to rotate. Adjusting the size of the pad 10 extending beyond the connecting head 3 allows the pad 10 to fit tightly against the inner wall of the bucket tooth block 4, thereby strengthening the connection between the bucket tooth block 4 and the connecting head 3 and preventing the bucket tooth block 4 from shaking. The adjustment of the pad 10 can be adjusted according to the different shapes of the bucket tooth blocks 4. Adjusting the number makes this device have a wider range of applications; then, the fixed shaft 7 is inserted into the fixed hole 20. Through the interference fit design between the fixed shaft 7 and the fixed hole 20, the fixed hole 20 can be enlarged, and the outer diameter of the rotating cylinder 8 can be increased at the same time, so that the rotating cylinder 8 is firmly fixed to the mounting hole 6 and the connecting hole 19, thereby firmly installing the bucket tooth block 4 and the connecting head 3. Moreover, with the cooperation of the pad block 10, the extrusion member 13 and the rotating cylinder 8, the rotation of the extrusion member 13 is limited, and the rotation of the extrusion member 13 is prevented from causing the connection between the pad block 10 and the inner wall of the bucket tooth block 4 to loosen.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
