Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a dustproof structure for shot blasting machines. Background Technology

[0002] Shot blasting machines use shot blasters to propel steel shot at high speed onto the surface of materials, generating impact and friction to remove surface dirt and defects, making the surface smoother and stronger, and improving surface strength and corrosion resistance. Therefore, shot blasting machines are widely used in aerospace, automotive, machine tool, mold, steel and other industries. At the same time, steel shot and other materials are recycled through conveyors and other equipment, thereby achieving efficient use of resources and energy.

[0003] However, the existing dustproof structure of shot blasting machines still has some problems in practical use: when shot blasting removes surface dirt from objects, the dirt particles that fall off may splash in the shot blasting chamber along with the shot particles, forming a certain floating state. At the same time, since a large amount of dust and other pollutants are generated during the shot blasting process, the particles may combine with other pollutants in the air to form secondary pollutants, further aggravating air pollution and thus affecting the breathing of on-site personnel. Utility Model Content

[0004] This utility model provides a dustproof structure for shot blasting machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The dustproof structure of the shot blasting machine includes an inverted conical tube and an adjustable dustproof mechanism. The adjustable dustproof mechanism includes a hollow rod, a support block fixedly connected to the middle of the surface of the hollow rod, a dustproof mesh plate rotatably connected to one end of the support block via a rotating shaft, a cleaning brush slidably connected to the inner wall of the dustproof mesh plate via a sliding groove, an adjusting rod rotatably connected to the middle of the upper end of the cleaning brush via a rotating shaft, a lifting rod rotatably connected to one end of the adjusting rod, and an adjusting handle fixedly connected to the top of the surface of the lifting rod.

[0007] As a further improvement to this technical solution: a limit slide rod is slidably connected to one side of the upper end of the hollow rod through a through hole; one end of the lifting rod is slidably connected to the inner wall of the hollow rod; and a mounting connecting plate is threadedly connected to the bottom of the surface of the hollow rod.

[0008] As a further improvement to this technical solution: a dust cover is slidably connected to one end of the mounting connecting plate, and a limiting plate is inserted into the lower end of the dust cover.

[0009] As a further improvement to this technical solution: one end of the limiting plate is fixedly connected to the top sleeve of the equipment, and the surface of the inverted conical tube is fixedly connected to the middle part of the inner wall of the top sleeve of the equipment.

[0010] As a further improvement to this technical solution: both sides of the top sleeve of the equipment are fixedly connected with snap-fit ​​limiting mechanisms, and the front and back of the top sleeve of the equipment are fixedly connected with support buckles.

[0011] As a further improvement to this technical solution: the locking and limiting mechanism includes a support frame, and the inner wall of the support frame is slidably connected to a slidable locking rod through a sliding groove, the slidable locking rod being made of rubber.

[0012] As a further improvement to this technical solution: a fixing block one is fixedly connected to the middle of the upper end of the sliding lever, and a rotating handle is engaged with the fixing block one side by opening a locking hole. A fixing block two is threadedly connected to one end of the rotating handle, and the lower end of the fixing block two is fixedly connected to the middle of the upper end of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0028] Please see Figs. 1-4 In this embodiment of the utility model, the dustproof structure of the shot blasting machine includes an inverted conical tube 1 and an adjustable dustproof mechanism 2. The adjustable dustproof mechanism 2 includes a hollow rod 201. A support block 202 is fixedly connected to the middle of the surface of the hollow rod 201. A dustproof mesh plate 203 is rotatably connected to one end of the support block 202 via a rotating shaft. A cleaning brush 204 is slidably connected to the inner wall of the dustproof mesh plate 203 through a sliding groove. An adjusting rod 205 is rotatably connected to the middle of the upper end of the cleaning brush 204 via a rotating shaft. A lifting rod 206 is rotatably connected to one end of the adjusting rod 205. An adjusting handle 207 is fixedly connected to the top of the surface of the lifting rod 206.

[0029] A thin rubber pad is attached to the surface of the lifting rod 206. When the lifting rod 206 slides up and down inside the hollow rod 201, the rubber pad increases the friction with the surface of the hollow rod 201, so that the lifting rod 206 can be positioned inside the hollow rod 201. The dustproof mesh plate 203 will not tilt downward due to the downward gravity and simultaneously pull the lifting rod 206 downward, thus positioning the tilt angle of the dustproof mesh plate 203.

[0030] Please see Fig. 3 One side of the upper end of the hollow rod 201 is slidably connected to a limit slide rod 208 through a through hole. One end of the lifting rod 206 is slidably connected to the inner wall of the hollow rod 201. The bottom of the surface of the hollow rod 201 is threaded with a mounting connecting plate 3.

[0031] The mounting connecting plate 3 can be directly connected to the hollow rod 201. When the adjustable dustproof mechanism 2 needs to be disassembled, the dustproof mesh 203 can be cleaned again later, so that the dustproof mesh 203 can achieve better results when it continues to play its dust-blocking role.

[0032] Please see Figs. 1-2 One end of the mounting connecting plate 3 is slidably connected to a dust cover 4, and the lower end of the dust cover 4 is inserted into a limit plate 5.

[0033] The dust cover 4 confines dust particles inside, and one end of the dust cover 203 is set to be arc-shaped and tangent to the arc-shaped inner wall of the dust cover 4, so that the dust cover 203 is not obstructed when it flips up and down.

[0034] Please see Figs. 1-2 One end of the limiting plate 5 is fixedly connected to the top sleeve 6 of the equipment, and the surface of the inverted conical tube 1 is fixedly connected to the middle of the inner wall of the top sleeve 6 of the equipment.

[0035] The inverted conical conical tube 1 allows for better flow guidance of solid particles during the flow process. Due to the gradual contraction of the cone, the particles experience a force converging towards the center as they move downwards, making them easier to remove.

[0036] Please see Figs. 1-2 Both sides of the top sleeve 6 of the equipment are fixedly connected with snap-fit ​​limiting mechanisms 7, and both the front and back of the top sleeve 6 of the equipment are fixedly connected with support buckles 8.

[0037] After the dust cover 3 is removed from the top sleeve 6 of the equipment, the support buckle 8 makes it easy to remove the top sleeve 6 of the equipment from the dust outlet of the shot blasting machine, and then clean the dust adhering to the inner wall of the top sleeve 6 of the equipment to avoid affecting the dustproof effect of the dustproof mesh plate 203.

[0038] Please see Fig. 4The locking and limiting mechanism 7 includes a support frame 701, and a slidable locking rod 702 is slidably connected to the inner wall of the support frame 701 through a sliding groove. The slidable locking rod 702 is made of rubber.

[0039] The sliding lever 702 engages with the edge of the dust outlet of the shot blasting machine. After the rubber sliding lever 702 contacts the edge of the dust outlet of the shot blasting machine, one end of the sliding lever 702 can undergo slight deformation when it is squeezed or twisted. This deformation allows the rubber surface to better fit the edge of the dust outlet of the shot blasting machine, thereby increasing the contact area and friction.

[0040] Please see Fig. 4 A first fixing block 703 is fixedly connected to the middle of the upper end of the sliding lever 702. A rotating handle 704 is attached to one side of the first fixing block 703 through a locking hole. A second fixing block 705 is threaded to one end of the rotating handle 704. The lower end of the second fixing block 705 is fixedly connected to the middle of the upper end of the support frame 701.

[0041] Rotate the handle 704 and move the fixed block 703 inward. At the same time, the sliding rod 702 slides inward within the limiting groove opened in the support frame 701, so that one end of the sliding rod 702 contacts the edge of the dust outlet of the shot blasting machine, and fixes the dust prevention mechanism and the dust outlet of the shot blasting machine in a fixed state.

[0042] The working principle of this utility model is as follows:

[0043] Place the top sleeve 6 of the equipment on top of the dust outlet of the shot blasting machine, and rotate the handle 704 to drive the sliding rod 702 to slide inward in the limiting groove within the support frame 701 until the sliding rod 702 is locked at the edge of the dust outlet and fixed. Pull the lifting rod 206 to make it slide up and down inside the hollow rod 201. Adjust the rotating rod 205 to make adaptive adjustments and change the tilt angle of the dust screen 203 according to the wind direction. After the shot blasting machine removes iron filings, the floating fixed particles are blocked by the dust screen 203. After the shot blasting machine stops operating, remove the adjustable dustproof mechanism 2 from the mounting connecting plate 3, and pull the adjusting handle 207 up and down in a relatively open area. The cleaning brush 204 slides in the limiting groove within the dust screen 203 and removes the dust from the dust screen 203. Later, the adjustable dustproof mechanism 2 is reinstalled on the mounting connecting plate 3 to continue the dust removal operation.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
