Description

Technical Field

[0001] The utility model relates to the field of shot blasting machines, in particular to a casting box-type shot blasting machine. Background Art

[0002] Shot blasting machine refers to a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of the casting. The shot blasting machine can simultaneously remove sand, core and clean the casting.

[0003] The shot blasting box of the shot blasting machine is mainly used to place metal components. When placing metal components, they are suspended by a wire rope through a crane and enter the shot blasting box. When the wire rope for hanging the metal components enters the shot blasting box, a strip opening is opened on the top for passing the wire rope. The existing strip opening is generally sealed with a rubber strip to prevent the dust generated by the shot blasting from spreading outward. However, long-term friction between the rubber and the wire rope will cause the rubber plate to wear, resulting in a poor seal and a risk of dust leakage. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a casting box-type shot blasting machine.

[0005] The utility model is realized through the following technical solutions:

[0006] The casting box-type shot blasting machine comprises a shot blasting box body and a strip opening on the top thereof for passing a hanging rope, a sealing component is arranged in the strip opening, and the sealing component comprises a plurality of sealing opening and closing units which are closely arranged and automatically opened and closed as the hanging rope passes through.

[0007] Further optionally, the sealing opening and closing unit includes two bending components extending toward the interior of the shot blasting box and having closed bottoms, and each bending component is hingedly fixed to the inner side of the corresponding strip-shaped opening.

[0008] Further optionally, the top of the bending component extends to the outside of the strip-shaped opening and is connected and fixed to the inclined pressing plate, and a counterweight is fixed to the lower outer end of the pressing plate.

[0009] Further optionally, a sealing plate is fixed on the pressing plate of each sealing opening and closing unit, and the two sealing plates are arranged in contact with each other.

[0010] Further optionally, the sealing plate is provided by rubber.

[0011] Further optionally, both sides of the bending component are provided with an inclination angle.

[0012] Compared with the existing technology, the beneficial effects of the utility model are: the utility model has a sealing component in the strip opening that automatically opens and closes the sealing opening and closing unit as the lifting rope passes through, which not only has less wear and tear and a longer service life, but also has better rigidity and flexibility in the upper and lower sealing to avoid material leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 yes Figure 1 A schematic enlarged view of the local structure in FIG.

[0015] Figure 3 It is a cross-sectional schematic diagram of the bending component of the utility model.

[0016] In the figure: shot blasting box 1, strip opening 2, bending part 3, pin shaft 4, pressing plate 5, counterweight block 6, sealing plate 7, metal component 8, and hanging rope 9. DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0018] like Figure 1 As shown, the casting box shot blasting machine includes a shot blasting box body 1 and a strip opening 2 on the top thereof for passing a hanging rope 9, a sealing assembly is arranged in the strip opening 2, and the sealing assembly includes a plurality of sealing opening and closing units which are closely arranged and automatically opened and closed as the hanging rope 9 passes through.

[0019] like Figure 2 As shown, the sealing opening and closing unit includes two bending parts 3 extending into the shot blasting box 1 and closed at the bottom. Each bending part 3 is hinged and fixed to the inner side of the corresponding strip opening 2. The bending part 3 is made of metal and is set at the first sealing point. It is a rigid seal, which not only has better sealing performance but also has a longer service life.

[0020] like Figure 2 As shown, the top of the bending component 3 extends to the outside of the strip opening 2 and is connected and fixed to the inclined pressing plate 5. A counterweight block 6 is fixed to the lower outer end of the pressing plate 5. The pressure of the counterweight block 6 allows the bending component 3 to return to its position quickly to ensure air tightness.

[0021] like Figure 2 As shown, a sealing plate 7 is fixed on the pressing plate 5 of each sealing opening and closing unit, and the two sealing plates 7 are arranged in contact with each other, and the sealing plates 7 are made of rubber.

[0022] like Figure 3 As shown, both sides of the bending part 3 are provided with inclined angles, and the set inclined angles facilitate the entry of the lifting rope 9 to make it more convenient and smooth to open the bending part 3.

[0023] The implementation principle of the casting box shot blasting machine of the application embodiment is:

[0024] When the driving vehicle enters the shot blasting box 1 by hanging the metal component 8 through the hanging rope 9 for shot blasting, the hanging rope 9 is aligned with the strip opening 2 and enters, and the closed sealing opening and closing units are opened one by one after entering the strip opening 2. The sealing opening and closing units are squeezed by the hanging rope 9, and the two bending parts 3 of the sealing opening and closing units are turned over at the pin shaft 4, so that the two bending parts 3 are unfolded to flow out of the gap to allow the hanging rope 9 to pass through;

[0025] When passing through to the next sealing opening and closing unit, the pressing plate 5 on the upper part of the sealing opening and closing unit at the front end is subjected to the gravity of the counterweight 6, causing the bending component 3 to flip in the opposite direction along the pin shaft 4 to achieve contact sealing, which fundamentally solves the wear problem caused by the flexible seal. The sealing opening and closing unit is a metal rigid seal with a long service life. At the same time, the sealing plate 7 on the upper part of the pressing plate 5 is always in a closed state to form 2 sealing points, which greatly improves the sealing of the strip opening 2 and prevents dust leakage.

[0026] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
