[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a scraper-type recovery device for abrasives in a sandblasting room. Background Art

[0002] In the sandblasting operation, in order to ensure the recycling of abrasives, an abrasive recovery system is usually used. The existing abrasive recovery methods include push rod type, spiral type, vibration plate type and wind-driven sand recovery. The push rod type sand recovery device has a high speed, and the abrasive will be broken and lost for the second time, so the abrasive loss is relatively large, resulting in waste. On the other hand, the push plate and abrasive of the push rod type sand recovery device are in contact with the floor, and the floor structure is very easy to wear; the spiral type, vibration plate type and wind-driven sand recovery device have the disadvantage of high noise, which affects the health of surrounding workers. Therefore, those skilled in the art provide a scraper-type recovery device for abrasives in a sandblasting room to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0025] See Figure 1 —— Figure 5 As shown, this specific embodiment adopts the following technical scheme: it includes a base 1, a sliding sand scraping assembly 2 and a driving mechanism 3; the base 1 is a frame structure, and a plurality of guide wheel groups 11 are respectively installed on the inner sides of the two side frames of the frame structure, and a connecting plate 12 is fixed on the base 1; the guide wheel group 11 is composed of two guide wheels 13, and the two guide wheels 13 are respectively installed on the inner sides of the two side frames of the frame structure of the base 1.

[0026] The sliding sand scraping assembly 2 comprises a frame support 21, a scraper shaft 22, a scraper 23, a mounting bracket 24, a one-way check rod 25 and a guide groove 26; guide grooves 26 are provided on both sides of the frame support 21 for slidingly cooperating with the guide wheel group 11, and the frame support 21 can slide along the guide grooves 26. A plurality of scrapers 23 are arranged in parallel on the frame support 21, and each scraper 23 is composed of a plurality of small scraper splits 29, and a plurality of small scraper splits 29 are installed in series on the scraper shaft 22. When one of the small scraper splits 29 is damaged, only the small scraper split 29 needs to be replaced, and there is no need to replace the entire scraper split 29, thereby reducing maintenance costs; a first mounting groove 27 and a second mounting groove 28 are provided on the mounting bracket 24, and the ends of the scraper shaft 22 and the one-way check rod 25 are respectively installed in the first mounting groove 27 and the first mounting groove 28 by screws. In the second mounting groove 28, the mounting bracket 24 is fixed to the inner side of the frame support 21, and the one-way check rod 25 is located on one side of the lower part of the scraper 23. The scraper 23 adopts a wear-resistant polyurethane scraper. The function of the one-way check rod 25 is that when the scraper 23 moves to the side without the one-way check rod 25, the one-way check rod 25 prevents the scraper 23 from bending, and plays a role in pushing the abrasive at the rear to ensure that the abrasive can be pushed. When the scraper 23 moves to the side with the one-way check rod 25, due to the lack of the one-way check rod 25, if there is abrasive at the bottom of the scraper 23, the scraper 23 will pass over these abrasives when it continues to move, so that the scraper 23 can be scraped the next time it moves to the side without the one-way check rod 25, thereby realizing the recovery of the abrasive; a number of reinforcing rods 210 are connected to the frame support 21, and the reinforcing rods 210 are used to reinforce the frame of the frame support 21.

[0027] The driving mechanism 3 includes a reducer mounting seat 31, a reducer 32, a crank 33 and a connecting rod 34; the reducer mounting seat 31 is fixed to one end of the frame support 21, the reducer 32 is installed on the reducer mounting seat 31, the reducer 32 is a hard-toothed reducer, a connecting rod 34 is installed on the output shaft of the reducer 32, the end of the connecting rod 34 is rotatably connected to the crank 33, the crank 33 is fixed to the connecting plate 12, the base 1 is fixed, and the reducer 32 drives the frame support 21 and its upper parts to slide reciprocatingly along the guide groove 26 through the crank-connecting rod mechanism, thereby realizing the reciprocating motion of the sliding sand scraping assembly 2.

[0028] The working principle of the utility model is as follows: the base 1 is fixed on the foundation in the sandblasting room, and several scraper recovery devices of the utility model are arranged in a front-to-back connection, and the reducer 32 drives the sliding sand scraping assembly 2 to reciprocate along the guide groove 26, so as to realize the reciprocating movement of the scraper 23 toward the side without the one-way check rod 25 and the side with the one-way check rod 25. Sliding toward the side without the one-way check rod 25 can achieve the purpose of recovering the abrasive, and sliding toward the side with the one-way check rod 25 can make the abrasive be collected on the side without the one-way check rod 25, and be scraped when the scraper 23 moves to the side without the one-way check rod 25 next time. The scraper 23 sends the pushed abrasive to the previous position in sequence, and finally enters the screw conveyor at the head end to complete the recovery.

[0029] The above shows and describes the basic principle and main features of the utility model and the 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 principle 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.
