DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a recycling and processing device for resin sand and steel shot, including a collecting barrel 1, three groups of feet 101 are fixedly installed at equal angles on the bottom of the collecting barrel 1, and six groups of positioning clamps 102 are fixedly installed at equal angles on the top of the collecting barrel 1, and the positioning clamps 102 correspond to the positioning sockets 203. By providing the positioning clamps 102, when the fixed barrel 2 is placed on the top of the collecting barrel 1, it is ensured that there is no misalignment between the collecting barrel 1 and the fixed barrel 2, and at the same time, the fixed barrel 2 is prevented from rotating on the top of the collecting barrel 1.

[0023] A fixed cylinder 2 is provided on the top of the collecting cylinder 1, and a stepped groove 201 is provided on the top of the fixed cylinder 2, and six groups of limiting protrusions 202 are fixedly installed at equal angles on the inner wall of the stepped groove 201. Positioning holes 203 are provided at equal angles on the bottom of the fixed cylinder 2. Because of the limiting protrusions 202, when the mounting frame 4 is clamped in the stepped groove 201, the limiting grooves 402 are clamped on the corresponding surfaces of the limiting protrusions 202, ensuring that when the mounting frame 4 is clamped on the top of the fixed cylinder 2, there will be no relative rotation between the mounting frame 4 and the fixed cylinder 2.

[0024] An L-shaped fixing plate 3 is symmetrically fixedly installed on the top of the surface of the fixing cylinder 2, and three groups of clamping rods 301 are slidably installed on the top of the L-shaped fixing plate 3, and one end of the three groups of clamping rods 301 passes through the L-shaped fixing plate 3 and is fixedly installed with a dial plate 302, and one end of the three groups of clamping rods 301 away from the dial plate 302 is fixedly installed with an L-shaped clamping plate 303, and a clamping spring 304 is provided on the surface of the clamping rod 301 located between the L-shaped fixing plate 3 and the L-shaped clamping plate 303. By providing a clamping spring 304, the L-shaped clamping plate 303 is pushed toward the top of the mounting frame 4 under the elastic action of the clamping spring 304, so that the L-shaped clamping plate 303 is pressed against the top of the mounting frame 4, and the mounting frame 4 is clamped and fixed to the stepped groove 201 at the top of the fixing cylinder 2;

[0025] A sliding groove 305 is symmetrically provided at the bottom of the L-shaped fixed plate 3, and a sliding protrusion 306 is symmetrically fixedly installed on one side of the bottom of the L-shaped card plate 303, and the sliding protrusion 306 passes through the sliding groove 305 and extends to the bottom of the L-shaped fixed plate 3. Because of the sliding protrusion 306, when the L-shaped card plate 303 is pushed to move on the top of the L-shaped fixed plate 3, the sliding protrusion 306 is driven to slide inside the sliding groove 305, ensuring that the L-shaped card plate 303 can always move closely on the top of the L-shaped fixed plate 3 and will not fall off.

[0026] A mounting frame 4 is provided at the top of the fixed cylinder 2, and a sieve plate 401 is fixedly installed at the bottom of the mounting frame 4. Six groups of limiting grooves 402 are provided at equal angles on the top of the surface of the mounting frame 4, and the limiting grooves 402 correspond to the limiting protrusions 202. By providing the sieve plate 401, when the mixture of resin sand and steel shot is poured into the top of the sieve plate 401, the resin sand can pass through the sieve holes of the sieve plate 401 and fall into the inside of the collecting cylinder 1, and the steel shot is blocked at the top of the sieve plate 401, and the mixture of resin sand and steel shot is screened.

[0027] The top of the mounting frame 4 is symmetrically provided with mounting grooves 403, and a handrail 404 is fixedly installed at a position corresponding to the top of the inner wall of the mounting frame 4 and the mounting groove 403. The top of the mounting frame 4 is located at the top of the two groups of mounting grooves 403 and the handrail 404. Because the handrail 404 is provided, the operator holds the two groups of handrails 404 to facilitate taking the mounting frame 4 out from the top of the fixed tube 2.

[0028] A rotating shaft 501 is rotatably installed at the bottom of the top plate 5, and a hand wheel 502 is fixedly installed on the top of the rotating shaft 501 through the top plate 5, and three groups of mounting plates 503 are fixedly installed at equal angles on the surface of the rotating shaft 501 located at the bottom of the top plate 5, and three groups of clamping rods 504 are slidably installed at the bottom of the mounting plate 503, and the top of the three groups of clamping rods 504 pass through the mounting plate 503 and are fixedly installed with a connecting plate 505. Because the rotating shaft 501 and the hand wheel 502 are provided, rotating the hand wheel 502 drives the rotating shaft 501 to rotate, thereby controlling the three groups of mounting plates 503 to rotate synchronously, so that the scraper 507 can rotate on the top of the screen plate 401, push the steel shots to roll, and prevent the steel shots from clogging the screen holes.

[0029] A clamping spring 508 is provided on the surface of the clamping rod 504 at the bottom of the mounting plate 503. A clamping plate 506 is fixedly installed at the bottom end of the three sets of clamping rods 504. Two sets of scrapers 507 are fixedly installed at the bottom of the clamping plate 506. The clamping spring 508 presses the clamping plate 506 downward so that the scraper 507 can be tightly attached to the top of the sieve plate 401, ensuring that when the scraper 507 pushes the steel shot stuck in the sieve hole, the scraper 507 can move up and down on the top of the sieve plate 401 without colliding hard with the steel shot to cause damage to the scraper 507.

[0030] The working principle of the utility model is:

[0031] Place the fixing cylinder 2 on the top of the collecting cylinder 1, insert the positioning column 102 into the corresponding positioning socket 203, select the appropriate mounting frame 4 and sieve plate 401, and insert the top plate 5 into the corresponding mounting groove 403. Under the elastic action of the compression spring 508, the scraper 507 is pressed against the top of the sieve plate 401. Push the L-shaped card plate 303 to both sides to put the mounting frame 4 into the stepped groove 201, so that the limiting groove 402 is stuck on the surface of the corresponding limiting protrusion 202, and release the L-shaped card plate. Under the rebound action of the clamping spring 304, the L-shaped clamping plate 303 is pushed toward the top of the mounting frame 4 and the top plate 5, and the mounting frame 4 and the top plate 5 are clamped and fixed inside the stepped groove 201, and a mixture of resin sand and steel shots is poured into the mounting frame 4. The hand wheel 502 is turned to control the rotating shaft 501 to drive the mounting plate 503 to rotate, so that the scraper 507 pushes the mixture of resin sand and steel shots on the top of the screen plate 401 to ensure that the steel shots will not block the screen holes, and the resin sand falls into the collecting tube 1 from the screen holes.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0033] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
