Description

Technical Field

[0001] The present invention belongs to the technical field of excavators, and specifically relates to an excavator breaker with a flattening function. Background Art

[0002] An excavator is a heavy engineering machinery and equipment driven by power and used for earthwork excavation, loading or handling operations through a robotic arm and a bucket. An excavator breaker is a hydraulic power mechanical device used in conjunction with an excavator, which breaks hard materials such as rocks and concrete through high-frequency impact force and is a key tool in demolition, excavation and resource recovery operations.

[0003] The patent with the publication number CN216973554U discloses an excavator breaker with a flattening function. The excavator breaker with a flattening function includes: a breaker body; a top plate fixedly installed on the top of the breaker body; a double-shaft motor fixedly installed on the top of the top plate; two driving rods respectively fixedly installed on the two output shafts of the double-shaft motor; two first bevel gears respectively fixedly installed at the ends of the two driving rods away from each other; two internal threaded pipes respectively rotatably installed on both sides of the breaker body; and two second bevel gears respectively fixedly installed at the tops of the two internal threaded pipes. The excavator breaker with a flattening function provided by this patent has the advantages of convenient use and the ability to switch between the flattening mode and the breaking mode.

[0017] 2. The excavator breaker hammer with a leveling function described in the present invention utilizes a multi-faceted synchronous self-cleaning component to scrape off the debris attached to the surfaces of the clapping plate, the curved plate, and the adjusting cloth through scraper plates one and two, thereby avoiding the debris adhering to the surfaces of the clapping plate, the curved plate, and the adjusting cloth due to moisture, thereby affecting the subsequent use effects of the three.

[0022] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a breaker hammer for an excavator with a flattening function, including a mounting shell 1, one end of the mounting shell 1 is fixedly connected to a frame 15, and a split-type crushing assembly is arranged on the frame 15; The split-type crushing assembly includes a bearing ring 7 fixedly connected to the lower end of the frame 15, a plurality of radial rods 8 are radially distributed and slidably connected on the bearing ring 7, one end of the radial rod 8 is fixedly connected to an arc plate 6, the inside of the arc plate 6 is slidably connected to a breaker head 5 through a chute, two ends of one side of the arc plate 6 are rotatably provided with rotating rollers 27, an adjusting cloth 14 is wound on the rotating rollers 27, and one end of the adjusting cloth 14 is fixedly connected to one side of the adjacent arc plate 6; A flattening mechanism is also arranged on the frame 15; The flattening mechanism includes two sliding rods 3 slidably connected to the middle of the upper end of the frame 15, and a flattening plate 4 is fixedly connected to the lower ends of the sliding rods 3.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figures 8 - 10 shown, one end of a radial rod 8 is rotatably provided with a first connecting rod 10, one end of the first connecting rod 10 is rotatably provided with a second connecting rod 11, and one end of the second connecting rod 11 is rotatably provided on the bearing ring 7.

[0024] One end of the second connecting rod 11 is fixedly connected with a gear 12, the gear 12 is rotatably provided on the bearing ring 7, an outer ring of the bearing ring 7 is sleeved and rotatably connected with a rotating ring 9, a tooth block 29 is intermittently arranged on the inner ring of the rotating ring 9, the gear 12 meshes with the tooth block 29, one side of the upper end surface of the bearing ring 7 is fixedly connected with a fixed block 30, one side of the upper end surface of the fixed block 30 is fixedly connected with a first motor 13, and an output end of the first motor 13 is fixedly connected with one end of the second connecting rod 11.

[0025] One side of the upper end surface of the frame 15 is fixedly connected with a hydraulic cylinder 2, and a piston end of the hydraulic cylinder 2 is fixedly connected with one side of the upper end surface of the flattening plate 4.

[0026] One side of the upper end of the crushing head 5 is threadedly connected with a second threaded rod 24, both ends of the second threaded rod 24 are rotatably provided on the arc-shaped plate 6, one side of the upper end of the arc-shaped plate 6 is fixedly connected with a fourth motor 25, and an output end of the fourth motor 25 is fixedly connected with one end of the second threaded rod 24.

[0027] One side of the upper end of the arc-shaped plate 6 is fixedly connected with a fifth motor 26, and an output end of the fifth motor 26 is fixedly connected with one end of the rotating roller 27.

[0028] Specifically, when the existing excavator breaker is in use, although after the objects such as stones are broken, the flattening plate 4 can be used to flatten them for subsequent construction. However, when the objects such as stones are broken, they will move to the surrounding due to vibration. When the broken blocks move out of the flattening range of the flattening plate 4, it is necessary to adjust the position of the flattening plate 4 to achieve uniform flattening, which is rather troublesome. Moreover, for some projects with strict requirements on the ground flatness and bearing capacity, such as highways, airport runways, and the foundations of large buildings, etc., it is necessary to refill the ground with qualified soil, sand and gravel materials after ground breaking, and then flatten the materials to ensure the ground flatness and bearing capacity. And when the broken blocks stay in the area to be refilled, it will affect the subsequent filling and flattening effects; Therefore, to solve the above problems, in the use of this embodiment, the installation shell 1 is connected to one end of the excavator's forearm; in the initial state, the multiple crushing heads 5 are closely attached to form a whole, and by driving the installation shell 1 to move through the excavator, the objects can be broken by hitting with the crushing heads 5.

[0029] 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 the other multiple gears 12 through the tooth block 29 of its inner ring, so that 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 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. At this time, the arc plate 6 and the adjusting cloth 14 cooperate with each other to surround the fragments, and then drive multiple arc plates 6 to move simultaneously and approach the center of the carrying ring 7, and the arc plate 6 and the adjusting cloth 14 can be used to push the fragments until the fragments are concentrated within the area of ​​the clapper board 4. At this time, the hydraulic cylinder 2 can be used to drive the clapper board 4 to descend, and the clapper board 4 can be used to flatten the fragments for subsequent construction. Moreover, before the fragments are flattened, they will be concentrated under the action of the arc plate 6 and the adjusting cloth 14, so that the clapper board 4 can flatten all the fragments at one time, avoiding the fragments from moving to the periphery due to vibration, causing the fragments to escape from the flattening range of the clapper board 4, and the position of the clapper board 4 needs to be adjusted multiple times to achieve uniform flattening, which is beneficial to improving the flattening efficiency. In addition, the crushing head 5 adopts a split design. When multiple crushing heads 5 are fitted, crushing work can be carried out. When separated, it does not affect the flattening work of the clapper board 4. The structure is reasonable and convenient.

[0030] When it is necessary to refill the ground with soil, sand, gravel and other materials that meet the requirements after crushing, 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 in the crushing area and leveled by the clapper 4, thereby avoiding the fragments staying in the area to be filled, thereby affecting the subsequent filling and leveling effects.

[0031] In this embodiment, Figure 3 , Figure 4 , Figure 7 As shown, the clapper board 4 is also provided with a multi-faceted synchronous self-cleaning component; The multi-sided synchronous self-cleaning component includes a cylinder 21 fixedly connected to the middle of the upper end face of the inner cavity of the batten 4. The piston end of the cylinder 21 is fixedly connected with a lifting block 19. A rotating shaft 18 is rotatably arranged in the middle of the lower end face of the lifting block 19. A first scraper 16 is fixedly connected to the lower end of the rotating shaft 18. Two second scrapers 17 are inserted and slidably connected to both sides of the first scraper 16. A strip-shaped groove 28 is arranged at the bottom of the batten 4, and the first scraper 16 and the second scraper 17 can pass through the strip-shaped groove 28.

[0032] A second motor 20 is fixedly connected to the middle of the upper end face of the lifting block 19, and the output end of the second motor 20 is fixedly connected to one end of the rotating shaft 18.

[0033] Two first threaded rods 23 are rotatably arranged in the inner cavity of the first scraper 16, and the first threaded rods 23 are threadedly connected to one side of the second scraper 17.

[0034] A third motor 22 is fixedly connected to the middle of one side of the inner cavity of the first scraper 16, and both output ends of the third motor 22 are fixedly connected to one end of the first threaded rod 23.

[0035] Specifically, in the above embodiment, since the batten 4, the arc-shaped plate 6, and the adjusting cloth 14 all come into contact with the fragments, and some of the fragments may be sticky due to moisture, it is easy for the fragments to adhere to the surfaces of the batten 4, the arc-shaped plate 6, and the adjusting cloth 14, thus affecting the subsequent use effects of the three. Therefore, to solve the above problems, when this embodiment is in use, after the clapper board 4, the arc-shaped plate 6, and the adjusting cloth 14 complete one operation, a plurality of arc-shaped plates 6 can be driven away from the axis of the bearing ring 7 to the extreme position. At this time, all parts of the adjusting cloth 14 are in a flat and straightened state. Then, the lifting block 19 is driven to descend by the air cylinder 21, so that the first scraper 16 and the second scraper 17 pass through the strip-shaped groove 28, and the upper edges of both are attached to the lower end surface of the clapper board 4. Moreover, the first threaded rods 23 on both sides are driven to rotate by the third motor 22, so that the two second scrapers 17 slide on the first scraper 16 at the same time until the ends of the second scrapers 17 are attached to the inner surface of the arc-shaped plate 6. At this time, the rotating shaft 18 is driven to rotate by the second motor 20, then the first scraper 16 and the second scraper 17 rotate at the same time. Since the upper edges of the first scraper 16 and the second scraper 17 are attached to the lower end surface of the clapper board 4, the first scraper 16 and the second scraper 17 can scrape off the fragments attached to the lower surface of the clapper board 4. At the same time, since the ends of the first scraper 16 and the second scraper 17 are attached to the inner surface of the arc-shaped plate 6, the fragments attached to the inner surface of the arc-shaped plate 6 can be scraped off. Since the adjusting cloth 14 is between two adjacent arc-shaped plates 6, the ends of the first scraper 16 and the second scraper 17 can also contact the surface of the adjusting cloth 14. At the same time, in cooperation with the lifting of the clapper board 4, the fragments attached to the surfaces of the clapper board 4, the arc-shaped plate 6, and the adjusting cloth 14 can be scraped off by the first scraper 16 and the second scraper 17, thus avoiding the situation that the fragments adhere to the surfaces of the clapper board 4, the arc-shaped plate 6, and the adjusting cloth 14 due to moisture, and further affecting the subsequent use effects of the three. Moreover, the cleaning work of the fragments on the surfaces of the three is carried out at the same time, and the cleaning efficiency is high.

[0036] Working principle: Connect the installation shell 1 to one end of the small arm of the excavator; in the initial state, a plurality of breaking heads 5 are closely attached to form a whole. By driving the installation shell 1 to move through the excavator, the object can be broken by hitting the object with the breaking heads 5.

[0037] 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 the other multiple gears 12 through the tooth block 29 of its inner ring, so that 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 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. At this time, the arc plate 6 and the adjusting cloth 14 cooperate with each other to surround the fragments, and then drive multiple arc plates 6 to move simultaneously and approach the center of the carrying ring 7, and the arc plate 6 and the adjusting cloth 14 can be used to push the fragments until the fragments are concentrated within the area of ​​the clapper board 4. At this time, the hydraulic cylinder 2 can be used to drive the clapper board 4 to descend, and the clapper board 4 can be used to flatten the fragments for subsequent construction. Moreover, before the fragments are flattened, they will be concentrated under the action of the arc plate 6 and the adjusting cloth 14, so that the clapper board 4 can flatten all the fragments at one time, avoiding the fragments from moving to the periphery due to vibration, causing the fragments to escape from the flattening range of the clapper board 4, and the position of the clapper board 4 needs to be adjusted multiple times to achieve uniform flattening, which is beneficial to improving the flattening efficiency. In addition, the crushing head 5 adopts a split design. When multiple crushing heads 5 are fitted, crushing work can be carried out. When separated, it does not affect the flattening work of the clapper board 4. The structure is reasonable and convenient.

[0038] When it is necessary to refill the ground with soil, sand, gravel and other materials that meet the requirements after crushing, 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 in the crushing area and leveled by the clapper 4, thereby avoiding the fragments staying in the area to be filled, thereby affecting the subsequent filling and leveling effects.

[0039] After the platen 4, the arc-shaped plate 6, and the adjusting cloth 14 complete one operation, drive the multiple arc-shaped plates 6 away from the axis of the bearing ring 7 to the limit position. At this time, all parts of the adjusting cloth 14 are in a flat and straightened state. Then, use the air cylinder 21 to drive the lifting block 19 to descend, so that the first scraper 16 and the second scraper 17 pass through the strip-shaped groove 28, and the upper edges of both are attached to the lower end surface of the platen 4. And, drive the first threaded rods 23 on both sides to rotate through the third motor 22, so that the two second scrapers 17 slide on the first scraper 16 at the same time until the end of the second scraper 17 is attached to the inner surface of the arc-shaped plate 6. At this time, drive the rotating shaft 18 to rotate by using the second motor 20, then the first scraper 16 and the second scraper 17 rotate at the same time. Since the upper edges of the first scraper 16 and the second scraper 17 are attached to the lower end surface of the platen 4, therefore, the first scraper 16 and the second scraper 17 can scrape off the fragments attached to the lower surface of the platen 4. At the same time, since the ends of the first scraper 16 and the second scraper 17 are attached to the inner surface of the arc-shaped plate 6, therefore, the fragments attached to the inner surface of the arc-shaped plate 6 can be scraped off. Since the adjusting cloth 14 is between two adjacent arc-shaped plates 6, therefore, the ends of the first scraper 16 and the second scraper 17 can also contact the surface of the adjusting cloth 14. At the same time, in cooperation with the lifting of the platen 4, the fragments attached to the surfaces of the platen 4, the arc-shaped plate 6, and the adjusting cloth 14 can be scraped off by the first scraper 16 and the second scraper 17, thus avoiding the situation that the fragments adhere to the surfaces of the platen 4, the arc-shaped plate 6, and the adjusting cloth 14 due to moisture, and further affecting the subsequent use effects of the three. And the cleaning work of the fragments on the surfaces of the three is carried out at the same time, with high cleaning efficiency.
