Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammers, and in particular to a breaker hammer anti-splashing and dust reduction structure. Background Art

[0002] A breaker hammer is a kind of engineering machinery equipment, which is usually used to break, demolish or cut hard materials such as concrete, rock, bricks, etc. in construction and demolition projects. When using the breaker hammer, it needs to be used in conjunction with the breaker hammer's anti-splash and dust reduction structure. The breaker hammer's anti-splash and dust reduction structure usually refers to a device or system used to reduce the dust and splash generated during the operation of the breaker hammer.

[0003] After searching, the utility model patent with the publication number CN215715670U discloses a structure for preventing splashing and reducing dust of a breaker hammer, which includes a breaker hammer, which is composed of a hammer body and a drill rod fixedly installed at one end of the hammer body, and the other end of the breaker hammer body is movably installed with the mechanical arm of the excavator. A protective cover with a telescopic structure is sleeved on the breaker hammer body and locked and fixed by a fixing member, and the lower end of the protective cover extends downward to completely cover the breaker hammer drill rod to form a shielding space for the breaker hammer drill rod to prevent the splashing of gravel; a spraying mechanism is provided in the protective cover near the end of the breaker hammer body to spray and reduce dust generated in the shielding space of the breaker hammer drill rod;

[0004] However, in the implementation of relevant technologies, the following problems were found: the existing anti-splash and dust reduction structure of the breaker hammer is provided with a spray mechanism inside the protective cover near the hammer body end of the breaker hammer. While the dust is initially controlled through the protective cover, the dust is sprayed and reduced through the spray mechanism, thereby further reducing the dust diffusion and reducing the impact of the dust on the surrounding environment. However, the spray mechanism needs to be used in conjunction with a water pump when in use. The start of the water pump will keep the nozzle in a spraying state. When the breaker hammer hits stones, rocks, roads, etc., dust is sprayed and reduced in the process. If the breaker hammer is still in a spraying state when it is lifted, the water will not be effectively used for dust reduction, but will be blown away by the wind in the air or fall into areas that do not need spraying, thereby causing a waste of water resources. Therefore, a breaker hammer anti-splash and dust reduction structure is needed. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a splash-proof dust-reducing structure for a breaker hammer.

[0006] The technical solution of the utility model is as follows: a breaker hammer anti-splash and dust reduction structure, comprising a breaker hammer and a mechanical arm arranged on the top of the breaker hammer, the mechanical arm is fixedly connected to a water tank at one end close to the breaker hammer, the outer wall of the breaker hammer is provided with a retractable splash cover that is snap-connected to the bottom of the water tank, the inner wall of the retractable splash cover is fixedly connected to an elastic sheet, and two dust reduction components for intermittently spraying dust in the retractable splash cover are symmetrically arranged on both sides of the retractable splash cover.

[0007] Preferably, the dust reduction component includes an elastic water bag, the bottom end of the elastic water bag is fixedly connected to a bag pushing plate, the bottom end of the bag pushing plate is fixedly connected to a force transmission rod, the bottom end of the telescopic splash cover is fixedly connected to a partition, the peripheral surface of the partition is fixedly connected to the bottom end of the force transmission rod, and the top end of the elastic water bag is fixedly connected to the bottom of the water tank.

[0008] Preferably, two sides of the top of the elastic water bag are fixedly connected with a one-way drainage pipe and a one-way water inlet pipe from left to right respectively.

[0009] Preferably, an annular groove is provided on the inner wall of the top of the telescopic splash guard, one end of the one-way drainage pipe away from the elastic water bag passes through the inner wall of the telescopic splash guard and extends to the inside of the annular groove, and one end of the one-way water inlet pipe away from the elastic water bag passes through the inner wall of the water tank and extends to the inside of the water tank.

[0010] Preferably, a plurality of water pipes are fixedly installed in an annular shape at equal intervals on the inner wall of the telescopic splash shield, one end of each of the water pipes is connected to the inside of the annular groove, and the other end of each of the water pipes is fixedly connected to a nozzle.

[0011] Preferably, a flexible fitting block is fixedly connected to the bottom of the partition to prevent gravel from splashing out of the telescopic splash shield from the gap at the bottom end of the partition.

[0012] The working principle and beneficial effects of the utility model are:

[0013] 1. The utility model is designed with a dust reduction component. When the breaker hits stones, rocks, road surfaces, etc., the telescopic splash shield will gradually telescope according to the depth of the breaker into the object, and at the same time, the elastic water bag will be squeezed by pushing the force transmission rod to discharge and spray the water source to reduce the generation of dust. When the breaker is lifted, the telescopic splash shield will use the elasticity of the elastic water bag to reset, and the water source will be sucked into the elastic water bag through the negative pressure generated to achieve self-replenishment of the water source. During this process, the nozzle will stop spraying so as to spray according to actual needs. This design can effectively control the splashing of dust and debris when the breaker is operating, improve the cleanliness and safety of the working environment, and at the same time, by automatically controlling the spraying of the water source, it can also save water resources and improve work efficiency.

[0014] 2. The flexible fitting block designed in the utility model can effectively reduce the gap between the bottom partition of the telescopic splash guard and the ground node, thereby improving the sealing performance of the splash guard. The flexible fitting block is made of soft materials such as rubber and can adapt to the unevenness of the ground, so that the telescopic splash guard fits more closely to the ground, reducing the gap that may be generated during the operation of the breaker. In this way, it can not only effectively prevent the splashing of dust and debris, but also improve the cleanliness and safety of the working environment.

[0015] 3. The utility model provides an elastic sheet on the inner wall of the telescopic splash shield to assist the telescopic splash shield in resetting, which not only enables the telescopic splash shield to withstand high-intensity impact force and improve the safety of the working environment, but also can further extend the life of the telescopic splash shield.

[0022] The following will be combined with 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 of 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.

[0023] See also Figures 1 to 4The utility model provides a technical solution for a breaker hammer anti-splashing and dust reduction structure: a breaker hammer anti-splashing and dust reduction structure, comprising a breaker hammer 1 and a mechanical arm 11 arranged on the top of the breaker hammer 1. The use of the breaker hammer 1 in conjunction with the mechanical arm 11 can improve work efficiency, ensure safety, reduce costs, and increase work flexibility. The mechanical arm 11 is fixedly connected to a water tank 3 at one end close to the breaker hammer 1. The outer wall of the breaker hammer 1 is provided with a telescopic splash shield 2 that is snap-connected to the bottom of the water tank 3. The inner wall of the telescopic splash shield 2 is fixedly connected to an elastic sheet 5. The elastic sheet 5 is also stacked. The design of the elastic sheet 5 can assist the telescopic splash shield 2 in resetting, and can withstand high-intensity impact force, thereby protecting the telescopic splash shield 2 and further extending its service life. A quarter of the top of the telescopic splash shield 2 is a non-stackable design for installing a water pipe 45 and a nozzle 46, and three quarters of the bottom of the telescopic splash shield 2 is a telescopic design for cooperating with the breaker hammer 1 to hit stones, rocks, roads, etc.

[0024] Furthermore, two dust suppression components 4 for intermittently spraying dust in the telescopic splash shield 2 are symmetrically provided on both sides of the telescopic splash shield 2, and the dust suppression component 4 includes an elastic water bag 43, and the bottom end of the elastic water bag 43 is fixedly connected to a bag pushing plate 42, and the bottom end of the bag pushing plate 42 is fixedly connected to a force transmission rod 41, and the bottom end of the telescopic splash shield 2 is fixedly connected to a partition 21, and the peripheral surface of the partition 21 is fixedly connected to the bottom end of the force transmission rod 41, and the top end of the elastic water bag 43 is fixedly connected to the bottom of the water tank 3, and the two sides of the top end of the elastic water bag 43 are fixedly connected from left to right with a one-way drainage pipe 44 and a one-way water inlet pipe 47, and the inner wall of the top end of the telescopic splash shield 2 is provided with an annular groove, and the one-way drainage pipe 44, one end away from the elastic water bag 43, passes through the inner wall of the telescopic splash shield 2 and extends to the inside of the annular groove, and the one-way drainage pipe Check valves are installed inside 44 and the one-way water inlet pipe 47. (Check valves belong to this type of valve, which include swing check valves and lift check valves. Swing check valves have a hinge mechanism and a valve disc like a door that rests freely on the inclined valve seat surface. In order to ensure that the valve disc can reach the appropriate position of the valve seat surface every time, the valve disc is designed in the hinge mechanism so that the valve disc has enough swing space and makes the valve disc truly and comprehensively contact the valve seat. The valve disc can be made of metal or leather, rubber or synthetic covering surface inlaid on the metal, depending on the performance requirements. When the swing check valve is fully opened, the fluid pressure is almost unimpeded, so the pressure drop through the valve is relatively small. The valve disc of the lift check valve is located on the valve body.On the upper valve seat sealing surface, this valve has the exception that the valve disc can be freely raised and lowered, and the rest of the valve is the same as the stop valve. The fluid pressure lifts the valve disc from the valve seat sealing surface, and the medium reflux causes the valve disc to fall back onto the valve seat and cut off the flow. According to the conditions of use, the valve disc can be a full metal structure, or it can be in the form of a rubber pad or a rubber ring embedded in the valve disc frame. Like the stop valve, the passage of the fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the flow rate of the swing check valve is rarely restricted). This technology is the prior art and will not be described in detail. The inner wall of the telescopic splash shield 2 is annularly equidistantly fixed with a plurality of water pipes 45, one end of which is connected to the inside of the annular groove, and the other end of which is fixedly connected to a nozzle 46. The end of the one-way water inlet pipe 47 away from the elastic water bag 43 penetrates the inner wall of the water tank 3 and extends to the inside of the water tank 3. When the breaker 1 hits the stone When the breaker 1 is inserted into the rock, road surface, etc., the telescopic splash shield 2 gradually telescopes with the insertion depth of the breaker 1. During the telescopic process, the partition plate 21 pushes the force transmission rod 41 to make the pushing plate 42 squeeze the elastic water bag 43, so that the water in the elastic water bag 43 is discharged into the annular groove through the one-way drainage pipe 44. At this time, the one-way drainage pipe 44 is opened and the one-way water inlet pipe 47 is closed, so that the water in the annular groove is gathered and transmitted to the nozzle 46 through a plurality of water pipes 45 for spraying, thereby reducing the dust in the telescopic splash shield 2. Effect: when the breaker 1 is lifted, the telescopic splash shield 2 is reset by the elasticity of the elastic water bag 43, and at the same time, the negative pressure generated by the reset of the elastic water bag 43 is used to suck the water source in the water tank 3 into the elastic water bag 43 through the one-way water inlet pipe 47. At this time, the one-way drainage pipe 44 is closed and the one-way water inlet pipe 47 is opened to realize water source replenishment. According to this design, the water source can be sprayed according to actual needs during the spraying and dust reduction process, and the spraying will stop when the breaker 1 is lifted, so as to prevent water waste;.

[0025] Furthermore, a flexible fitting block 6 is fixedly connected to the bottom of the partition 21 to prevent gravel from splashing out of the telescopic splash shield 2 from the gap at the bottom of the partition 21. The setting of the flexible fitting block 6 can prevent the formation of gaps at the nodes between the bottom partition 21 of the telescopic splash shield 2 and the ground to a certain extent. The material of the flexible fitting block 6 can be soft material such as rubber, which can adapt to the unevenness of the ground, so that the breaker 1 can better contact with the ground during operation and reduce the generation of gaps.

[0026] The working principle and use process of the utility model are as follows: when the breaker 1 hits stones, rocks, road surfaces, etc., the telescopic splash shield 2 will gradually telescope according to the depth of the breaker 1 into the stones, rocks, road surfaces, etc. During this process, the elastic water bag 43 is squeezed by pushing the force transmission rod 41 to discharge and spray the water source, which can achieve a dust reduction effect. When the breaker 1 is lifted, the telescopic splash shield 2 will be reset by the elasticity of the elastic water bag 43, and the negative pressure generated by the elastic water bag 43 will be used to suck the water source into the elastic water bag 43 to achieve self-replenishment of the water source. During this process, the nozzle 46 stops spraying, so that the nozzle 46 sprays according to actual needs, thereby achieving the purpose of preventing water waste.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
