Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a scraper mechanism of a scraper type conveyor used for abrasive recovery 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, the technicians in this field provide a scraper mechanism of a scraper conveyor for abrasive recovery in a sandblasting room to solve the problems raised in the above background technology. Summary of the invention

[0003] The utility model aims to provide a scraper mechanism of a scraper conveyor for abrasive recovery in a sandblasting room, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: it includes a base and a sliding scraping assembly; the sliding scraping assembly includes a frame support, a scraper shaft, a scraper, a mounting bracket, a one-way check rod, an adjustment groove, a first mounting groove, a second mounting groove and a screw; a plurality of scrapers are arranged side by side on the frame support, and the plurality of scrapers are respectively mounted on the scraper shaft, a first mounting groove and a second mounting groove are provided on the mounting bracket, an adjustment groove is provided on the outer side of the first mounting groove, the screw passes through the adjustment groove and is fixed to the scraper shaft, the one-way check rod is fixed in the second mounting groove by a screw, the mounting bracket is fixed on the inner side of the frame support, and the one-way check rod is located on one side of the lower part of the scraper; the two sides of the frame support are slidably connected in the base.

[0005] Furthermore, each scraper is composed of a plurality of small scraper parts, and the plurality of small scraper parts are installed in series on the scraper shaft.

[0006] Furthermore, the scraper is made of wear-resistant polyurethane scraper.

[0007] Furthermore, a plurality of reinforcing rods are connected to the frame support.

[0008] After adopting the above structure, the beneficial effects produced by the utility model are as follows: the scraper mechanism of the scraper conveyor for recycling abrasives in a sandblasting room described in the utility model, when the abrasive is recycled, only the scraper is in contact with the abrasive and the abrasives move displacedly with each other, without friction with any other parts, and the abrasives are recycled slowly and evenly, thereby completely avoiding the secondary crushing loss of the abrasives. Since the abrasives are pushed slowly and evenly, there is almost no wear on the floor structure, thereby saving abrasives, greatly extending the service life of the floor, greatly reducing the cost of use, and running without noise.

[0013] Base 1, sliding sand scraping assembly 2, frame support 21, scraper shaft 22, scraper 23, mounting bracket 24, one-way check rod 25, adjustment groove 26, first mounting groove 27, second mounting groove 28, screw 29, small scraper split 210, reinforcement rod 211. DETAILED DESCRIPTION

[0014] 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.

[0015] See Figure 1 —— Figure 3 As shown, this specific embodiment adopts the following technical scheme: it includes a base 1 and a sliding scraper assembly 2; the sliding scraper assembly 2 includes a frame support 21, a scraper shaft 22, a scraper 23, a mounting bracket 24, a one-way check rod 25, an adjustment groove 26, a first mounting groove 27, a second mounting groove 28 and a screw 29; a plurality of scrapers 23 are arranged in parallel on the frame support 21, each scraper 23 is composed of a plurality of small scraper splits 210, and a plurality of small scraper splits 210 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 without replacing the entire scraper split, thereby reducing maintenance costs.

[0016] The mounting bracket 24 is provided with a first mounting groove 27 and a second mounting groove 28. The mounting bracket 24 at the first mounting groove 27 is provided with an adjusting groove 26. The screw 29 passes through the adjusting groove 26 and is fixed to the scraper shaft 22. When the bottom of the scraper 23 is worn, the screw 29 moves downward along the adjusting groove 26. The fixed position of the scraper shaft 22 is adjusted so that the bottom of the scraper 23 can contact the floor. The worn scraper 23 can be reused, thereby reducing the replacement frequency.

[0017] The one-way check rod 25 is fixed in the second mounting groove 28 by screws, and the mounting bracket 24 is fixed on the inner side of the frame support 21. 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 the sliding sand scraping assembly 2 is driven by the reciprocating drive mechanism to perform reciprocating motion. 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 they can be scraped the next time the scraper 23 moves to the side without the one-way check rod 25, thereby realizing the recovery of the abrasive.

[0018] Both sides of the frame support 21 are slidably connected in the base 1 . A plurality of reinforcing rods 211 are connected to the frame support 21 . The reinforcing rods 211 are used to reinforce the frame of the frame support 21 .

[0019] 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.
