Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collection technology, specifically to a dust collection device. Background Technology
[0002] Drilling is an essential process in coal mining. Using pneumatic or electric tools with drill rods, a large amount of mine dust is generated during the operation. Some of this dust is suspended in the air to form floating dust, while some settles into accumulated dust. At the same time, a small amount of water needs to be injected into the borehole to reduce the temperature of the drill rod. This causes water to accumulate on the floor of the underground roadway, making the roads muddy and posing a great safety hazard to the underground workers' walking and construction.
[0003] With the increasing mechanization of mining operations, the concentration of dust during processes such as drilling is constantly increasing, potentially even reaching the critical point for dust explosion. Currently, most mines use spray-type dust suppression. However, spray-type dust suppression can cause water accumulation on the floor of underground mine roadways, making roads muddy and posing significant safety hazards to underground workers' movement and work.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] according to Figure 1 As shown, this embodiment provides a dust collection device, which includes a support rod 10, a sliding component 20, and a dust collection umbrella 30. The support rod 10 is a hollow rod that can be fitted onto the drill rod. When the drill rod is working, it can collect the mineral dust it generates in a timely manner to achieve the dust reduction effect. At the same time, it can collect water to reduce the temperature of the drill rod, thus reducing water accumulation on the roadway floor without the need for spray dust suppression.
[0028] The support rod 10 is sleeved with the sliding component 20 and the dust collection umbrella 30. The sliding component 20 is connected to the dust collection umbrella 30. The support rod 10 is provided with a retractable protrusion (not shown in the figure). The sliding component 20 can slide up and down in the support rod 10, allowing the dust collection umbrella 30 to be in an open or closed state. It is fixed by the retractable protrusion. The open state of the dust collection umbrella 30 is as follows: Figure 1 As shown, the dust collection umbrella 30 has its canopy facing down and its inner surface facing up. Multiple retractable protrusions can be provided according to actual needs, for example, five, to adjust the opening area of the dust collection umbrella 30 and thus control the dust collection area.
[0029] The sliding assembly 20 includes a first umbrella rib 21, a second umbrella rib 22, and a sliding ring 23. Each umbrella rib is composed of multiple supporting rods. The first umbrella rib 21 and the second umbrella rib 22 are formed by eight supporting rods. The sliding ring 23 is fitted onto the circumference of the supporting rod 10 and is hinged to the first umbrella rib 21. One end of the eight supporting rods of the first umbrella rib 21 is evenly distributed on the circumference of the sliding ring 23. The other end of the first umbrella rib 21 is connected to the dust collection umbrella 30 via a snap-fit connection. The middle of the dust collection umbrella 30 is fixed to the other end of the first umbrella rib 21.
[0030] The dust collection umbrella 30 is fixed to the support rod 10 by a fixing ring 31, which is positioned above the sliding ring 23. The dust collection umbrella 30 includes supporting umbrella ribs (not shown) and umbrella fabric (not shown). The umbrella fabric is supported by the supporting umbrella ribs, which bend upwards to support the umbrella fabric. The middle part of the supporting umbrella ribs is fixed to the other end of the first umbrella rib 21. The end of the supporting umbrella ribs is equipped with a suction cup (not shown), which is used to adhere the dust collection umbrella to the underground rock wall, further improving the dust reduction effect. The number of supporting umbrella ribs is the same as the number of supporting rods of the first umbrella rib 21, and their ends are evenly distributed on the circumference of the fixing ring 31.
[0031] One end of the second umbrella rib 22 is fixed on the circumference of the fixing ring 31, and the other end is connected to the first umbrella rib 21. The other end of the second umbrella rib 22 is connected to the middle of the first umbrella rib 21. Its function is to support the first umbrella rib 21 so that the first umbrella rib 21 can better open or close the dust collection umbrella 30.
[0032] The working principle of the dust collection device in this embodiment is as follows:
[0033] according to Figure 1 As shown, the dust collection umbrella 30 is in the open state at this time. When the sliding ring 23 is moved downward along the support rod 10, the first umbrella rib 21 drives the second umbrella rib 22 to contract towards the center of the support rod 10, so that the dust collection umbrella 30 is drawn towards the center of the support rod 10 and then the dust collection umbrella 30 is closed.
[0034] If the sliding ring 23 is moved upward along the support rod 10, the corresponding retractable protrusion is selected when the sliding ring 23 moves upward according to the required dust collection area of the dust collection umbrella 30. The sliding ring 23 drives the first umbrella rib 21 to move upward, causing one end of the second umbrella rib 22 to unfold outward along the support rod 10, thereby supporting the first umbrella rib 21, which in turn supports the dust collection umbrella 30, thus opening the dust collection umbrella 30. If the uppermost retractable protrusion is selected, the dust collection umbrella 30 can be fully opened. When the dust collection umbrella 30 is open, it can be adhered to the underground rock wall by the suction cups at the ends of the supporting umbrella ribs, improving the dust reduction effect.
[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
