Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

As shown in figures 1-3, a rubber particle batch multistage screening machine comprises a feeding hopper 1, and the bottom end of the feeding hopper 1 is communicated with a screening channel with a high left and a low right. The screening channel is formed by combining a chute 5 and a screening cover plate 2 covered on the chute 5, and a plurality of rows of screening teeth 2c are arranged in the screening channel. In order to avoid the poor screening effect caused by the short residence time of the rubber particles in the screening channel, the front and back of the adjacent rows of screen teeth 2c are preferably staggered.

A plurality of sieve meshes have been seted up to chute 5's bottom, and the sieve mesh is used for sieving out less rubber granule to drop in chute 5's below, consequently, when implementing the operation, can place the accumulator who is used for receiving less rubber granule in chute 5's below. Preferably, the chute 5 is convergent from left to right. Screening apron 2 is last to be seted up apron door 2d, and preferably, the left side of apron door 2d is equipped with handle 2 a. The upper ends of the rows of the screen teeth 2c are fixed on the cover plate door 2d, and the lower ends of the screen teeth are propped against the bottom of the chute 5. The interval that is located between two sieve teeth 2c on same row is greater than the aperture of sieve mesh, sieve tooth 2c is used for sifting out great rubber granule, and let great rubber granule stop in the screening passageway, in order to avoid causing the jam to the screening passageway, preferably, sieve tooth 2c leans on the terminal setting of screening passageway, the screening of sieve mesh on chute 5, some rubber granule that is less than the sieve mesh has been sifted out, therefore, the rubber granule who stays in the screening passageway has reduced, filter great rubber granule again this moment, then can follow to a certain extent and avoid blocking up. The centrally sized rubber particles larger than the screen openings and smaller than the screen teeth 2c fall out of the end of the chute 5, so that a recovery chute for receiving the centrally sized rubber particles can be placed at the end of the chute 5.

The front end and the rear end of the screening cover plate 2 extend to the outside of the chute 5 and are fixed on the ground through the fixing support 4, and the bottom side of the left end of the chute 5 is downwards provided with a first chute 5b extending front and rear along the axis. The right end of chute 5 is seted up the second spout 5a that the axis extends around towards the right side, is equipped with two crossbeams 4a of card respectively in first spout 5b and second spout 5a on the fixed bolster 4. Chute 5 is through first spout 5b and second spout 5a sliding connection on fixed bolster 4, is equipped with the screening power device that is used for promoting chute 5 around on the fixed bolster 4. The inconsistent opening orientation of first spout 5b and second spout 5a can satisfy the support, can avoid removing about again.

Preferably, the right-hand member of apron door 2d rotates to be connected on screening apron 2, and the right-hand member of apron door 2d rotates to be connected through the round pin axle and extends splice plate 3, extends splice plate 3 and is located chute 5 right side. Specifically, both sides all extend right around the apron door 2d right-hand member and form two and connect journal stirrup 2b, and two connect journal stirrup 2b and be located the terminal front and back both sides of chute 5 respectively, and the top that extends splice plate 3 is passed through the round pin hub rotation and is connected on connecting journal stirrup 2 b. The top of extending splice plate 3 is equipped with the high overlap joint step 3a in low right side in a left side, and the left side of extending splice plate 3 sets firmly the rotation horizontal pole 4b that is used for putting the extension splice plate 3 upside down, rotates horizontal pole 4b and fixes on fixed bolster 4. When the cover plate door 2d is lifted up from the chute 5, the extension splice plate 3 is driven to rotate to the inverted state by the rotating cross rod 4b, and the lap joint step 3a is just lapped at the tail end of the chute 5, so as to form the extension of the chute 5.

Preferably, the edge of the second sliding groove 5a, which is located near the bottom side, extends rightward to form the overlapping edge 5c, so that the overlapping step 3a can overlap the overlapping edge 5c when the extension splice plate 3 is rotated to the upside-down state. The lap joint point can be lower than the bottom of the chute 5, so that larger particles can fall out conveniently.

After the screening finishes, open apron door 2d, drive through apron door 2d and extend splice plate 3 and rotate to make extension splice plate 3 rotate to the state of putting upside down under the effect of rotating horizontal pole 4 b. When the cover plate door 2d is opened, the screen teeth 2c can be driven to leave the groove bottom of the chute 5, and after the larger rubber particles are not blocked by the screen teeth 2c, the rubber particles can fall on the extension splicing plate 3 from the tail end of the chute 5 and fall out from the tail end of the extension splicing plate 3. At this time, a recovery groove for receiving larger rubber particles may be placed at the end of the extension splice plate 3.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
