Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic breaker hammers, in particular to a dust reduction type hydraulic breaker hammer. Background Art

[0002] A hydraulic breaker, also known as a hydraulic breaker or a hydraulic rock breaker, is an important working tool of a hydraulic excavator. It can also be installed on an excavator loader or a wheel loader for crushing operations. A hydraulic breaker uses high-pressure liquid generated by a hydraulic system to drive the piston to reciprocate at high speed, thereby exerting impact force on the material to achieve a crushing effect.

[0003] In order to carry out crushing operations, when a hydraulic breaker is needed for assistance, the base is first installed on the excavator, and then the hydraulic cylinder cooperates with the hydraulic system to generate high pressure to drive the drill rod body to move back and forth up and down, and then exert impact force on the building materials to carry out crushing operations; but during the use of the hydraulic breaker, the stones produced by the crushed materials will splash, and then a large amount of dust will be generated. The emitted dust will block the excavator operator's line of sight and will have a certain impact on the on-site environment, and then affect the construction and work efficiency of the crushing operation, thereby affecting the use of the hydraulic breaker.

[0011] Preferably, a spring is connected to the bottom end of the fixing ring, and a rubber ring is sleeved on the middle part of the outer wall of the drill rod body.

[0012] Preferably, a threaded seat is threadedly connected to the bottom end of the outer wall of the drill rod mounting seat.

[0014] Preferably, a mounting seat is sleeved on the outer wall of the fixing rod, and an electric push rod is butted against the bottom end of the mounting seat, and a support plate is butted against the bottom end of the electric push rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: when the dust reduction type hydraulic breaker is in use, the dust-laden air is introduced into the dust suction box through the dust reduction mechanism, and the sprayed water flow contacts the dust in the air to reduce the dust, thereby reducing the dust concentration during the operation of the hydraulic breaker to prevent it from affecting the health of the workers, thereby facilitating dust reduction, and assisting the downward movement of the drill rod body through the auxiliary mechanism, thereby making the impact force of the downward movement of the drill rod body greater, and buffering the movement of the drill rod body through the spring, thereby facilitating the downward movement and buffering when the hydraulic breaker is in use.

[0016] 1. During the crushing operation by the hydraulic breaker, the dust box is first started to generate suction at the dust bucket, and then the dusty air is introduced into the dust box, and the water flow inside the water storage tank is introduced into the jet plate through the outlet pipe, and then the water flow is sprayed out through the jet hole on the jet plate. At this time, the water flow contacts the dust in the air to reduce the dust, and then reduce the dust concentration during the operation of the hydraulic breaker to prevent it from affecting the health of the workers, thereby playing a role in facilitating dust reduction during the use of the hydraulic breaker;

[0017] 2. During the crushing operation by the hydraulic breaker, the spring will be squeezed and deformed when the drill rod body moves upward. Then the spring resets to generate elastic force to assist the drill rod body to move downward, thereby making the impact force of the drill rod body moving downward greater. When the drill rod body breaks the material, it will be affected by the recoil and move to a certain extent. At this time, the kinetic energy generated by the recoil is absorbed by the deformation of the spring, and then it is buffered, so that when the hydraulic breaker is used, it plays a role in assisting downward movement and buffering.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 3The utility model provides a technical solution: a dust reduction type hydraulic breaker, comprising a base 1, a hydraulic cylinder 2 and a drill rod body 4, a hydraulic cylinder 2 is installed in the middle of the inner wall of the base 1, and a drill rod mounting seat 3 is connected to the bottom end of the hydraulic cylinder 2, and the drill rod body 4 is slidably connected inside the drill rod mounting seat 3, a dust reduction mechanism 5 is arranged on the outer wall of the hydraulic cylinder 2, and the dust reduction mechanism 5 comprises a dust suction box 501, a water storage tank 502, a dust suction pipe 503, a dust suction bucket 504, a limit seat 505, an inlet pipe 506, an outlet pipe 507 and a jet plate 508, a dust suction box 501 is connected to one side of the base 1, and another dust suction box 501 is connected to the base 1. One side is connected to a water tank 502, and a dust suction pipe 503 is connected to one side of the outer wall of the dust suction box 501; the bottom end of the dust suction pipe 503 is connected to a dust suction hopper 504, and the middle part of the outer wall of the dust suction pipe 503 is connected to a limiting seat 505; the middle part of the outer wall of the water tank 502 is connected to an inlet pipe 506, and the bottom end of the outer wall of the water tank 502 is connected to an outlet pipe 507; the bottom end of the outlet pipe 507 is connected to a jet plate 508, and a jet hole is opened inside the jet plate 508; both sides of the top of the jet plate 508 are welded to the base 1; the outer wall of the limiting seat 505 is connected to the base 1, and the dust suction box 501 and the water tank 502 are parallel to each other.

[0028] In specific implementation, during the crushing operation by the hydraulic breaker, in order to prevent the dust generated by the crushed material from spreading everywhere, dust reduction treatment is required. Since the dust box 501 is connected to the dust hopper 504 through the dust pipe 503, the dust box 501 is first started to generate suction force out of the dust hopper 504, and then the air is sucked into the dust pipe 503. Then, the dust-carrying air is introduced into the dust box 501 through the dust pipe 503, and at this time, the dust pipe 503 is limited by the limit seat 505, and then the dust generated in the crushing operation is collected;

[0029] When the dust concentration is too high and the dust collection box 501 alone cannot meet the demand, since the outlet pipe 507 is connected to the water tank 502, the water flow inside the water tank 502 is first discharged through the outlet pipe 507, and the water flow is injected into the water tank 502 through the inlet pipe 506 in advance, and then the water flow is introduced into the spray plate 508, and then discharged through the spray hole on the spray plate 508. At this time, the sprayed water flow contacts the dust in the air to reduce the dust, thereby reducing the dust concentration during the operation of the hydraulic breaker and preventing it from affecting the health of the staff. In addition, water flow is not used for dust reduction at ordinary times, thereby reducing the consumption of water resources, thereby facilitating dust reduction during the use of the hydraulic breaker.

[0030] See also Figure 1 , Figure 2 , Figure 4 and Figure 5It can be seen that an auxiliary mechanism 6 is arranged inside the drill rod mounting seat 3, and the auxiliary mechanism 6 includes a fixing ring 601, a spring 602, a rubber ring 603 and a threaded seat 604. A fixing ring 601 is welded to the top of the inside of the drill rod mounting seat 3; a spring 602 is connected to the bottom end of the fixing ring 601, and a rubber ring 603 is sleeved on the middle part of the outer wall of the drill rod body 4; the threaded seat 604 is threadedly connected to the bottom end of the outer wall of the drill rod mounting seat 3; the inner wall of the spring 602 is connected to the drill rod body 4, and the fixing ring 601 and the drill rod mounting seat 3 form an integrated structure.

[0031] In the specific implementation, during the crushing operation by the hydraulic breaker, the threaded seat 604 is first rotated to connect with the bottom end of the drill rod mounting seat 3, and then when the drill rod body 4 reciprocates to work, the threaded seat 604 blocks the small gravels that are splashed, preventing them from entering the inside of the drill rod mounting seat 3 and affecting the work;

[0032] Because the inner wall of the spring 602 is connected to the drill rod body 4, the spring 602 on the fixing ring 601 is squeezed when the drill rod body 4 moves upward, causing the spring 602 to deform. Thereafter, the spring 602 resets to generate elastic force to assist the drill rod body 4 to move downward, thereby making the impact force of the drill rod body 4 moving downward greater, and the drill rod body 4 will be affected by the rebound when breaking the material and move to a certain extent. At this time, the kinetic energy generated by the rebound is absorbed by the deformation of the spring 602, and then buffered. Moreover, because a rubber ring 603 is sleeved on the middle part of the outer wall of the drill rod body 4, the rubber ring 603 can reduce the collision between the drill rod body 4 and the drill rod mounting seat 3 when the drill rod body 4 moves downward, thereby facilitating the downward assistance and buffering when the hydraulic breaker is in use.

[0033] See also Figure 1 , Figure 6 and Figure 7 It can be seen that a supporting mechanism 7 is provided on the outer wall of the base 1, and the supporting mechanism 7 includes a fixing rod 701, a fixing seat 702, an electric push rod 703 and a supporting plate 704. A fixing rod 701 is welded on the middle part of the outer wall of the base 1; a fixing seat 702 is sleeved on the outer wall of the fixing rod 701, and the bottom end of the fixing seat 702 is connected to the electric push rod 703, and the bottom end of the electric push rod 703 is connected to the supporting plate 704; the top end of the supporting plate 704 is connected to the output end of the electric push rod 703, and a fixing hole corresponding to the fixing rod 701 is opened inside the fixing seat 702.

[0034] In specific implementation, when the hydraulic breaker is used for crushing operation, when the hydraulic breaker needs to be installed on the crushing equipment, since the outer wall of the base 1 is welded to the fixing rod 701, the fixing seat 702 is first moved to dock with the fixing rod 701, and then the electric push rod 703 is set on both sides of the base 1, and then the electric push rod 703 is started. Since the output end of the electric push rod 703 is connected to the support plate 704, the electric push rod 703 extends to drive the support plate 704 to move downward;

[0035] After the support plate 704 is fixed to the ground, the electric push rod 703 continues to extend to drive the base 1 to move upward, so that the height of the base 1 is close to the crushing equipment, thereby freeing the hands of the staff to install the hydraulic breaker. At this time, the electric push rod 703 assists in supporting the base 1. After that, it is only necessary to disconnect the fixing seat 702 from the fixing rod 701 to remove the electric push rod 703 from the base 1, thereby facilitating the auxiliary installation of the hydraulic breaker when it is used.

[0036] To sum up, when this dust reduction type hydraulic breaker is used, the base 1 is first installed on the excavator, and then the hydraulic cylinder 2 cooperates with the hydraulic system to generate high pressure to drive the drill rod body 4 to move back and forth up and down, and then exert impact force on the building materials to perform crushing operations. This is the prior art and will not be elaborated on here. The dust-carrying air is introduced into the dust suction box 501 through the dust reduction mechanism 5, and the spraying water flow contacts the dust in the air to reduce dust, thereby reducing the dust concentration during the operation of the hydraulic breaker to prevent it from affecting the health of the workers. The auxiliary mechanism 6 assists the drill rod body 4 to move downward, thereby making the impact force of the drill rod body 4 moving downward greater, and the spring 602 is used to buffer the movement of the drill rod body 4, and the support mechanism 7 makes the height of the base 1 close to the crushing equipment, thereby freeing both hands and facilitating the workers to install the hydraulic breaker. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
