The fragments in the crushing area will be pushed away from the crushing area by the arc plate and the adjusting cloth, so that the fragments in the crushing area can be cleared, and then the soil, sand and gravel and other materials that meet the requirements can be filled into the crushing area, and leveled by the clapper, thereby avoiding the problem of fragments staying in the area to be filled and affecting the subsequent filling and leveling effects.

[0023] 2. The excavator breaker hammer with a leveling function described in the present invention utilizes a multi-faceted synchronous self-cleaning component, which can scrape off the debris attached to the surfaces of the clapper plate, curved plate, and adjusting cloth through scraper one and scraper two, thereby avoiding the situation where the debris adheres to the surfaces of the clapper plate, curved plate, and adjusting cloth due to moisture, thereby affecting the subsequent use effects of the three.

[0036] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please refer to Figures 1-10The present invention provides a technical solution: an excavator breaker hammer with a leveling function, comprising a mounting shell 1, one end of which is fixedly connected to a frame 15, and a split crushing assembly is provided on the frame 15;

[0038] The split crushing assembly includes a carrying ring 7 fixedly connected to the lower end of the frame 15, and a plurality of radial rods 8 are radially distributed and slidably connected to the carrying ring 7. One end of the radial rod 8 is fixedly connected to an arc plate 6, and the inner side of the arc plate 6 is slidably connected to the crushing head 5 through a chute. Rotating rollers 27 are rotatably provided at both ends of one side of the arc plate 6. An adjusting cloth 14 is wound around the rotating roller 27, and one end of the adjusting cloth 14 is fixedly connected to one side of the adjacent arc plate 6.

[0039] The frame 15 is also provided with a flattening mechanism;

[0040] The leveling mechanism includes two slide bars 3 slidably connected to the middle of the upper end of the frame 15 , and the lower ends of the slide bars 3 are fixedly connected to the clapping plates 4 .

[0041] In this embodiment, Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figures 8-10 As shown, a connecting rod 10 is rotatably provided at one end of the radial rod 8, a connecting rod 2 11 is rotatably provided at one end of the connecting rod 10, and one end of the connecting rod 2 11 is rotatably provided on the carrying ring 7.

[0042] One end of the connecting rod 2 11 is fixedly connected to a gear 12, and the gear 12 is rotatably set on the carrying ring 7. The outer ring of the carrying ring 7 is sleeved and rotatably connected to the rotating ring 9. The inner ring of the rotating ring 9 is intermittently provided with tooth blocks 29. The gear 12 and the tooth blocks 29 are engaged with each other. One side of the upper end face of the carrying ring 7 is fixedly connected to a fixed block 30, and one side of the upper end face of the fixed block 30 is fixedly connected to a motor 13. The output end of the motor 13 is fixedly connected to one end of the connecting rod 2 11.

[0043] One side of the upper end surface of the frame 15 is fixedly connected with a hydraulic cylinder 2, and the piston end of the hydraulic cylinder 2 is fixedly connected to one side of the upper end surface of the clapper 4.

[0044] One side of the upper end of the crushing head 5 is threadedly connected to a threaded rod 24, both ends of the threaded rod 24 are rotatably set on the arc plate 6, one side of the upper end of the arc plate 6 is fixedly connected to a motor 4 25, and the output end of the motor 4 25 is fixedly connected to one end of the threaded rod 24.

[0045] One side of the upper end of the arc-shaped plate 6 is fixedly connected to a motor 5 26 , and the output end of the motor 5 26 is fixedly connected to one end of the rotating roller 27 .

[0046] Specifically, when the existing excavator breaker hammer is in use, although the clapper 4 can be used to flatten the stone and other objects after they are broken to facilitate subsequent construction, when the stone and other objects are broken, they will move to the surrounding areas due to vibration. When the broken pieces are out of the flattening range of the clapper 4, the position of the clapper 4 needs to be adjusted to achieve uniform flattening, which is rather troublesome. In addition, for some projects with strict requirements on ground flatness and bearing capacity, such as highways, airport runways, and foundations of large buildings, it is necessary to refill the ground with soil, sand and gravel that meet the requirements after the ground is broken, and then flatten the materials to ensure the flatness and bearing capacity of the ground. When the broken pieces stay in the area to be filled, it will affect the subsequent filling and flattening effects.

[0047] Therefore, in order to solve the above problems, when using this embodiment, the mounting shell 1 is connected to one end of the excavator's arm; the multiple crushing heads 5 in the initial state are tightly fitted and form a whole. When the mounting shell 1 is driven to move by the excavator, the crushing heads 5 can hit the object to perform the crushing work.

[0048] When it is necessary to flatten the fragments on the ground, according to the distribution range of the fragments, the motor 13 drives the gear 12 to rotate, so that the rotating ring 9 rotates, and the rotating ring 9 will rotate through the tooth block 29 of its inner ring, so that the other multiple gears 12 rotate, then the connecting rod 2 11 and the connecting rod 1 10 rotate, and the radial rod 8 will slide on the carrying ring 7 due to the rotation of the connecting rod 10 and the connecting rod 2 11, so that the multiple arc plates 6 move away from each other, and the multiple tightly fitted crushing heads 5 are separated. At the same time, the motor 5 26 drives the rotating roller 27 to rotate, and unwinds the adjusting cloth 14, so that the unwound part of the adjusting cloth 14 is always in a taut state. When the crushing head 5 moves a certain distance, the motor 4 25 drives the threaded rod 2 24 to rotate, so that the multiple crushing heads 5 are driven to rise at the same time until the bottom of the crushing head 5 is higher than the bottom of the arc plate 6, and then the arc plate 6 is driven to descend until the bottom of the arc plate 6 contacts the ground. The paving chute 6 and the adjusting cloth 14 are used to push the paving chute 4 to the center of the support ring 7, and the paving chute 6 and the adjusting cloth 14 are used to push the paving chute 4 to the center of the support ring 7.

[0049] When it is necessary to refill the ground with soil, sand, gravel and other materials that meet the requirements after crushing the ground, and then level the materials, after crushing the ground, the crushing head 5 can be first raised to a position where its bottom is higher than the bottom of the arc plate 6, and then the arc plate 6 is driven down to contact the ground. At this time, the arc plate 6 is in the center of the crushing area, and then the above-mentioned arc plate 6 movement and adjusting cloth 14 unwinding work are repeated, so that the encirclement formed by the arc plate 6 and the adjusting cloth 14 gradually becomes larger. At the same time, the fragments in the crushing area will be pushed away from the crushing area by the arc plate 6 and the adjusting cloth 14, so that the fragments in the crushing area can be cleared, and then the materials are filled into the crushing area and leveled by the clapper 4, thereby avoiding the situation where the fragments stay in the area to be filled, thereby affecting the subsequent filling and leveling effects.

[0050] In this embodiment, Figure 3 、 Figure 4 、 Figure 7 As shown, the clapper 4 is also provided with a multi-faceted synchronous self-cleaning component;

[0051] The multi-faceted synchronous self-cleaning component includes a cylinder 21 fixedly connected to the middle of the upper end surface of the inner cavity of the clapper 4, the piston end of the cylinder 21 is fixedly connected to the lifting block 19, and the middle of the lower end surface of the lifting block 19 is rotatably provided with a rotating shaft 18. The lower end of the rotating shaft 18 is fixedly connected to scraper 16, and scraper 2 17 is plugged and slidably connected on both sides of scraper 16. A strip groove 28 is provided at the bottom of the clapper 4, and scraper 16 and scraper 2 17 can pass through the strip groove 28.

[0052] A second motor 20 is fixedly connected to the middle portion of the upper end surface of the lifting block 19 , and an output end of the second motor 20 is fixedly connected to one end of the rotating shaft 18 .

[0053] Two threaded rods 23 are rotatably provided in the inner cavity of the scraper 16, and the threaded rod 23 is threadedly connected to one side of the scraper 2 17.

[0054] A motor 3 22 is fixedly connected to the middle of one side of the inner cavity of the scraper 16 , and the output ends on both sides of the motor 3 22 are fixedly connected to one end of the threaded rod 1 23 .

[0055] Specifically, in the above embodiment, since the clapper 4, the curved plate 6, and the adjusting cloth 14 are all in contact with the debris, and some of the debris may be sticky due to moisture, it is easy for the debris to adhere to the surfaces of the clapper 4, the curved plate 6, and the adjusting cloth 14, thereby affecting the subsequent use of the three.

[0056] Therefore, in order to solve the above problems, when the present embodiment is in use, after the clapper 4, the curved plate 6 and the adjusting cloth 14 complete one work, the multiple curved plates 6 can be driven away from the axis of the carrying ring 7 to the limit position. At this time, all parts of the adjusting cloth 14 are flat and straightened, and then the cylinder 21 is used to drive the lifting block 19 to descend, so that the scraper 16 and the scraper 2 17 pass through the strip groove 28, and the upper end edges of the two are in contact with the lower end surface of the clapper 4, and the motor 3 22 drives the threaded rod 1 23 on both sides to rotate, so that the two scrapers 17 slide on the scraper 1 16 at the same time until the end of the scraper 2 17 is in contact with the inner surface of the curved plate 6. At this time, the motor 2 20 is used to drive the rotating shaft 18 to rotate, so that the scraper 1 16 and the scraper 2 17 rotate at the same time. The edge is in contact with the lower end surface of the clapper 4, so the scraper 16 and the scraper 2 17 can scrape off the debris attached to the lower surface of the clapper 4. At the same time, since the ends of the scraper 16 and the scraper 2 17 are in contact with the inner surface of the curved plate 6, the debris attached to the inner surface of the curved plate 6 can be scraped off. Since the adjusting cloth 14 is between two adjacent curved plates 6, the ends of the scraper 16 and the scraper 2 17 can also contact the surface of the adjusting cloth 14. At the same time, in conjunction with the lifting and lowering of the clapper 4, the scraper 16 and the scraper 2 17 can scrape off the debris attached to the surfaces of the clapper 4, the curved plate 6, and the adjusting cloth 14, thereby avoiding the situation where the debris adheres to the surfaces of the clapper 4, the curved plate 6, and the adjusting cloth 14 due to moisture, thereby affecting the subsequent use effects of the three, and the debris cleaning work on the surfaces of the three is carried out simultaneously, with high cleaning efficiency.

[0057] Working principle: Connect the mounting shell 1 to one end of the excavator's arm; in the initial state, multiple crushing heads 5 fit tightly together and form a whole. When the mounting shell 1 is driven by the excavator to move, the crushing heads 5 can hit the object to perform crushing work.

[0058] When it is necessary to flatten the fragments on the ground, according to the distribution range of the fragments, the motor 13 drives the gear 12 to rotate, so that the rotating ring 9 rotates, and the rotating ring 9 will rotate through the tooth block 29 of its inner ring, so that the other multiple gears 12 rotate, then the connecting rod 2 11 and the connecting rod 1 10 rotate, and the radial rod 8 will slide on the carrying ring 7 due to the rotation of the connecting rod 10 and the connecting rod 2 11, so that the multiple arc plates 6 move away from each other, and the multiple tightly fitted crushing heads 5 are separated. At the same time, the motor 5 26 drives the rotating roller 27 to rotate, and unwinds the adjusting cloth 14, so that the unwound part of the adjusting cloth 14 is always in a taut state. When the crushing head 5 moves a certain distance, the motor 4 25 drives the threaded rod 2 24 to rotate, so that the multiple crushing heads 5 are driven to rise at the same time until the bottom of the crushing head 5 is higher than the bottom of the arc plate 6, and then the arc plate 6 is driven to descend until the bottom of the arc plate 6 contacts the ground. The paving chute 6 and the adjusting cloth 14 are used to push the paving chute 4 to the center of the support ring 7, and the paving chute 6 and the adjusting cloth 14 are used to push the paving chute 4 to the center of the support ring 7.

[0059] When it is necessary to refill the ground with soil, sand, gravel and other materials that meet the requirements after crushing the ground, and then level the materials, after crushing the ground, the crushing head 5 can be first raised to a position where its bottom is higher than the bottom of the arc plate 6, and then the arc plate 6 is driven down to contact the ground. At this time, the arc plate 6 is in the center of the crushing area, and then the above-mentioned arc plate 6 movement and adjusting cloth 14 unwinding work are repeated, so that the encirclement formed by the arc plate 6 and the adjusting cloth 14 gradually becomes larger. At the same time, the fragments in the crushing area will be pushed away from the crushing area by the arc plate 6 and the adjusting cloth 14, so that the fragments in the crushing area can be cleared, and then the materials are filled into the crushing area and leveled by the clapper 4, thereby avoiding the situation where the fragments stay in the area to be filled, thereby affecting the subsequent filling and leveling effects.

[0060] After the clapper 4, the curved plate 6 and the adjusting cloth 14 have completed one work, the multiple curved plates 6 can be driven away from the axis of the carrying ring 7 to the limit position. At this time, all parts of the adjusting cloth 14 are flat and straight. Then, the cylinder 21 is used to drive the lifting block 19 to descend, so that the scraper 1 16 and the scraper 2 17 pass through the strip groove 28, and the upper edges of the two are in contact with the lower end surface of the clapper 4. In addition, the threaded rod 1 23 on both sides is driven by the motor 3 22 to rotate, so that the two scrapers 2 17 slide on the scraper 1 16 at the same time until the end of the scraper 2 17 is in contact with the inner surface of the curved plate 6. At this time, the motor 2 20 is used to drive the rotating shaft 18 to rotate, so that the scraper 1 16 and the scraper 2 17 rotate at the same time. Since the upper edges of the scraper 16 and the scraper 2 17 are in contact with the lower end surface of the clapper 4, Therefore, scraper 16 and scraper 2 17 can scrape off the debris attached to the lower surface of the clapper 4. At the same time, since the ends of scraper 16 and scraper 2 17 are in contact with the inner surface of the curved plate 6, the debris attached to the inner surface of the curved plate 6 can be scraped off. Since the adjusting cloth 14 is between two adjacent curved plates 6, the ends of scraper 16 and scraper 2 17 can also contact the surface of the adjusting cloth 14. At the same time, in conjunction with the lifting and lowering of the clapper 4, the scraper 16 and scraper 2 17 can scrape off the debris attached to the surfaces of the clapper 4, the curved plate 6, and the adjusting cloth 14, thereby avoiding the situation where the debris adheres to the surfaces of the clapper 4, the curved plate 6, and the adjusting cloth 14 due to moisture, thereby affecting the subsequent use effects of the three. Moreover, the debris cleaning work on the surfaces of the three is carried out simultaneously, and the cleaning efficiency is high.
