Description

Technical Field

[0001] The present invention relates to the technical field of breaking picks, and particularly relates to a dust prevention device for a breaking pick. Background Art

[0002] In engineering fields such as mine exploitation, road construction, and building demolition, breaking picks are widely used as important breaking tools. When a breaking pick performs a breaking operation on hard materials such as rocks and concrete, a large amount of fine debris and dust will be generated, which will not only pollute the working environment, reduce visibility, and affect the operator's line of sight, but also spatter debris and increase the operation risk.

[0003] Currently, there are many deficiencies in the existing breaking picks in terms of preventing debris and dust. At present, most of them use simple sprinkler devices in the construction area to suppress dust, but the coverage area of the sprinkler device is limited, and the water volume is difficult to accurately control. If the water volume is too small, it cannot effectively reduce dust, and if the water volume is too large, it will cause the working surface to be muddy, affecting the normal use of the breaking pick and subsequent construction. Therefore, it is urgent to develop a dust prevention device for a breaking pick to solve the problems existing in the prior art and improve the environmental protection and safety of the breaking operation. In view of this, we propose a dust prevention device for a breaking pick. Summary of the Invention

[0053] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer to Figures 1-12 , the present invention details the above technical solutions through the following embodiments:

[0055] The breaker pick anti-dust device in this embodiment, as shown in the structures of Figure 1 and Figure 2 , the breaker pick 1 includes a pick base 11 installed with a pick head 12. Installing this device outside the pick head 12 can absorb dust during breaking and achieve the functions of dust collection and scraping to prevent blockage.

[0056] Specifically, it includes an inner cover assembly 4. An inner cover cylinder 44 with a through hole 441 provided in the cylinder body is sleeved outside the pick head 12, as Figure 7 shown in the structure. At the same time, in cooperation with Figure 1 and Figure 2 the installation relationship shown, in this embodiment, an intermediate disk 42 and a sleeve frame 41 are fixedly connected in sequence above the inner cover cylinder 44. The intermediate disk 42 is provided with a shaft hole 421 for the pick head 12 to insert.

[0057] It should be explained that since the impact depth of the pick head 12 is inconsistent during impact crushing operation, this device needs to have an adjustable structure to avoid damage to the device caused by hitting the substrate to be broken during hard installation. Therefore, in this embodiment, the sleeve frame 41 is detachably installed on the pick base 11. A first lug 111 for inserting the screw 2 is provided on the outer wall of the pick base 11, and a second lug 411 for threadedly installing the screw 2 and aligned with the position of the first lug 111 is provided on the outer wall of the sleeve frame 41. And as Figure 1 shown in the position relationship, a spring 3 is sleeved on the screw 2. Based on the elasticity of the spring 3 and the gravity of the device, it can keep in contact with the crushing base surface, and at the same time, the spring 3 can be compressed without affecting the crushing operation function, and the probability of dust escape is also reduced.

[0058] Considering that it is necessary to collect the sucked dust and crushed stones, and it is necessary to avoid dust accumulation blocking the holes and affecting the continuous dust suction effect. Therefore, in this embodiment, an outer cover 5 is threadedly installed at the outer edge of the intermediate disk 42 outside the inner cover cylinder 44. A dust scraping assembly 7 is rotatably installed at the dust suction clamping cavity 10 between the outer cover 5 and the inner cover cylinder 44. And a bottom support cover 6 is threadedly installed at the bottom of the outer cover 5, which can collect the dust settled or filtered in the dust suction clamping cavity 10 into the bottom support cover 6. Subsequently, the bottom support cover 6 can be threadedly disassembled, and the disassembly and cleaning are convenient.

[0059] In this embodiment, in order to better suck the dust, otherwise it will escape again during the process of lifting and transferring the pick head 12. Therefore, a suction assembly 8 is conductively installed at the through port 51 of the outer cover 5 for sucking the operation dust, including a dust suction hood 81 installed at the through port 51. An L-shaped suction pipe 83 with an upward opening is detachably installed outside the dust suction hood 81. A suction fan 84 is installed in the L-shaped suction pipe 83, so that the dust can be sucked into the dust suction clamping cavity 10 through the inner cover cylinder 44 and scraped and collected into the bottom support cover 6 by the dust scraping assembly 7.

[0060] In this embodiment, in order to keep the suction assembly 8 unobstructed, a filter screen plate 82 that fits the inner wall of the inner cover of the outer cover 5 is installed at the through port 51. At the same time, a filter screen with a pore diameter smaller than that of the filter screen plate 82 is installed at the connection end of the L-shaped suction pipe 83, and the L-shaped suction pipe 83 can be regularly disassembled to clean the accumulated dust in the pipe.

[0061] The dust scraping assembly 7 is mainly located at the dust suction clamping cavity 10 of the outer cover 5, and will not affect the impurity dust collected below the bottom support cover 6 due to rotation. Specifically, the dust scraping assembly 7 is as shown in Figures 8-11 . It includes a transmission ring 71 with a scraping unit 73 fixedly connected coaxially at the bottom end. The inner wall of the inner ring of the transmission ring 71 is provided with teeth 711, and a driving gear 72 meshing with the teeth 711 is installed at the same time. A driving motor 9 is fixedly installed on the middle disk 42 to drive the driving gear 72. At the same time, in order to achieve limiting, four L-shaped supporting blocks 43 are detachably installed around the middle disk 42, and the transmission ring 71 is horizontally supported by the L-shaped supporting blocks 43 to realize the rotation of the dust scraping assembly 7.

[0062] It should be noted that the suction assembly 8 needs to maintain a normal air flow path. However, conventional rotating wheels or scraping wheels located in the dust suction clamping cavity 10 will form a similar partition structure, that is, they cannot effectively suck or overload and damage the exhaust fan 84. Therefore, the scraping unit 73 of this embodiment is as shown in Figures 8-10 . It is provided with a first open ring block 731 and a second open ring block 732 fixedly connected coaxially up and down. The two are respectively provided with ventilation openings 7302 symmetrically arranged at the center. The ventilation openings 7302 can play a role in conducting the inner cover cylinder 44 and the dust suction cover 81, forming a dust suction flow path. And it should be noted that dust has the property of escaping, and dust will continuously accumulate at the through holes of the suction path, which is easy to block. Therefore, it is necessary to consider avoiding blockage.

[0063] Therefore, as shown in Figure 11 , this embodiment creatively provides scraping blocks 703 at both ends of the ventilation opening 7302 for fitting on the outer wall of the inner cover cylinder 44. At the same time, scraping convex blocks 701 are provided around the first open ring block 731 and the second open ring block 732 for fitting on the inner wall of the outer cover 5. The scraping blocks 703 and the scraping convex blocks 701 can scrape off dust to avoid blockage. At the same time, a falling material vertical groove 702 for providing a dust falling channel is provided between adjacent scraping convex blocks 701. Internal threads 7301 are provided on the inner ring walls of the first open ring block 731 and the second open ring block 732. When the scraping unit 73 rotates, dust can be scraped down along the internal threads 7301 and the falling material vertical groove 702 into the bottom support cover 6. Overall, the cleaning is convenient and the dust suction is reliable, and the dust can be stably suppressed.

[0064] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions of each component in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0065] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention.
