[0026] The following is a further description of the present utility model in conjunction with the attached Figures 1-5 diagram.

[0027] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a scraper conveyor with a particle grading function.

[0028] In a specific technical solution, it includes a bracket 1 and a screening component 2;

[0029] As Figures 1-3 shown, the screening component 2 is installed above the bracket 1. The screening component 2 is used for screening and conveying materials. The screening component 2 includes a sieve plate 201 installed at the top of the bracket 1 and a top plate 202 located between the brackets 1. The sieve plate 201 can support the materials. When the top plate 202 is closed, it can seal the bottom of the sieve plate 201. When the top plate 202 is opened, it is convenient for the materials to fall. The top plate 202 is rotatably installed at the bottom of the sieve plate 201. A motor 203 with an output shaft fixedly connected to the top plate 202 is fixedly installed on the side wall of the sieve plate 201. The motor 203 can drive the top plate 202 to rotate. Two arranged chutes 3 are opened on the top plate 202. The chutes 3 facilitate the downward penetration of the baffle 204. A baffle 204 penetrating through the chutes 3 is fixedly installed at the bottom of the sieve plate 201. The baffle 204 can prevent materials of different particle sizes from being mixed. A push post 205 is fixedly installed on the top of the top plate 202. The push post 205 can drive the top plate 202 to move. Sieve holes 4 are opened on the sieve plate 201. The sieve holes 4 can screen the materials. The baffle 204 divides the sieve plate 201 into three areas. The sizes of the sieve holes 4 in each area are different. The sieve holes 4 near the motor 603 are larger. The sizes of the sieve holes 4 in the middle area are moderate. The sieve holes 4 far from the motor 603 are smaller.

[0030] When materials need to be conveyed, the top plate 202 covers the lower part of the sieve plate 201. The top plate 202 can seal the sieve holes 4 to prevent the materials from leaking through the sieve holes 4, which is convenient for transporting the materials. When materials need to be screened, by starting the motor 203 to drive the top plate 202 to rotate, the top plate 202 rotates downward. The top plate 202 moves away from the sieve holes 4. After the top plate 202 rotates, it presents an inclined state. The materials falling from the sieve holes 4 fall onto the top plate 202. The materials falling along the top plate 202 can be recovered. The baffle 204 can separate the materials falling from the sieve holes 4 of different sizes on the top plate 202 to prevent the materials from being mixed.

[0031] As Figure 1 and Figures 3-4As shown in the figure, an oscillation component 5 is installed on one side of the bracket 1. The oscillation component 5 is used to drive the screening component 2 to vibrate reciprocally. The oscillation component 5 includes a first side plate 501 fixedly installed on one side of the bracket 1, a limiting cylinder 502, and a spring 503. The first side plate 501 can fix one end of the limiting cylinder 502 and the spring 503. The limiting cylinder 502 can support the spring 503. The spring 503 can drive the sieve plate 201 to reset. The spring 503 is arranged inside the limiting cylinder 502. The limiting cylinder 502 and the spring 503 are fixedly installed between the first side plate 501 and the sieve plate 201. A second motor 504 is fixedly installed on the side wall of the first side plate 501. The second motor 504 can drive the rotor 505 to rotate. A rotor 505 located on one side of the push column 205 is fixedly installed on the output shaft of the second motor 504. The rotor 505 can toggle the push column 205.

[0032] When the top plate 202 rotates, it drives the push column 205 to rotate. The push column 205 is vertical on one side of the rotor 505. By starting the second motor 504 to drive the rotor 505 to rotate, the rotor 505 is oval. One end of the rotor 505 far from the central axis of the second motor 504 presses the push column 205. The movement of the push column 205 drives the movement of the top plate 202. The top plate 202 drives the movement of the sieve plate 201. The sieve plate 201 pulls the spring 503, and the spring 503 gives the sieve plate 201 a reverse pulling force. After one end of the rotor 505 far from the central axis of the second motor 504 moves away from the push column 205, the push column 205 loses the extrusion force, causing the top plate 202 to lose the thrust force. The top plate 202 drives the sieve plate 201 to lose the thrust force. The spring 503 pulls the sieve plate 201 to reset. The sieve plate 201 can perform reciprocating motion. The shaking of the sieve plate 201 can drive the shaking of the materials on the sieve plate 201, and the materials can be shaken loose to prevent material accumulation.

[0033] As Figure 1 and Figure 5 As shown in the figure, a power component 6 is installed on the bracket 1. The power component 6 is used to convey materials. The power component 6 includes a first bearing 601 and a second bearing 602 symmetrically penetrated through the upper side wall and the lower side wall of the bracket 1, and a third motor 603 fixedly installed on the side wall of the bracket 1. The first bearing 601 and the second bearing 602 can support the chain 604. The third motor 603 can drive the first bearing 601 to rotate. The output shaft of the third motor 603 is fixedly connected to one of the first bearings 601. Chains 604 are symmetrically sleeved on the side walls of the first bearing 601 and the second bearing 602. The chain 604 can support the scraper 605. A plurality of scrapers 605 are arranged on the chain 604. The scraper 605 can push the materials.

[0034] The starting motor three 603 drives the connected bearing one 601 to rotate counterclockwise. The bearing one 601 drives the chain 604 to rotate, and the chain 604 drives the scraper 605 to rotate. The scraper 605 at the top of the sieve plate 201 moves from the sieve holes 4 with a smaller diameter to the sieve holes 4 with a larger diameter, sending the material onto the sieve plate 201. The scraper 605 can push the material to move.

[0035] As Figure 1 and Figure 4 shown, a second side plate 7 is fixedly installed on the side wall of the bracket 1. The first side plate 501 and the second side plate 7 can prevent the material from spilling out from one side of the sieve plate 201.

[0036] As Figure 2 and Figure 5 shown, fixing blocks 8 located at the bottom of the sieve plate 201 are symmetrically installed on the top of the bracket 1. The fixing blocks 8 can support the sieve plate 201.

[0037] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
