in the figure:

a sieve box 1; a box main body 2; a screen layer 3; a screen section 4; a rotating shaft 5; a first side wall 6; a block group 7; a second side wall 8; a third side wall 9; a discharge opening 10.

Detailed Description

In order to further explain the technical solution of the present invention, the following is a detailed explanation through specific examples.

As shown in fig. 1-3, a novel automatic wood chip shaking and screening device comprises a screen box 1; the screen box 1 comprises a box main body 2, more than two screen layers 3 which are vertically arranged in the box main body 2 and a first driving device for driving the screen layers 3 to turn over; the screen layer 3 comprises more than two screen segments 4 arranged along the length direction of the screen layer 3; the screen section 4 comprises a rotating shaft 5 extending in the width direction of the screen layers 3. In practical implementation, the first driving device comprises a driving motor; the wood chips enter the box main body 2 from a feed port at the upper end of the screen box 1, and the screen layer 3 also enters the box main body 2 through the feed port; when the shaking screen equipment runs for a period of time, the wood chips cannot pass through the screen holes to block the screen holes, the screen layer 3 is driven by the first driving device to turn over, so that the wood chips are separated from the screen holes, and the screen holes are smooth; specifically, when the upset, the long limit of screen cloth layer 3 overturns, for avoiding the mutual interference collision between screen cloth layer 3, through decomposing screen cloth layer 3 into two above screen cloth segments 4, driving motor drive screen cloth segment 4 overturns respectively, decomposes the long limit of screen cloth layer 3 into two above minor faces, and then avoids the mutual interference collision between screen cloth layer 3.

Preferably, the box body 2 comprises two first side walls 6, one on each side of the mesh layer 3; the screen section 4 is in rotational connection with the first side wall 6. In the practical implementation process, the screen section 4 is supported by the first side wall 6, and the screen section 4 is rotatably connected with the first side wall 6, so that the screen section 4 can be conveniently turned over.

Preferably, the first side wall 6 has more than two block sets 7 corresponding to the screen segments 4 one by one and supporting the screen segments 4. In the practical implementation process, the screen section 4 is supported through the baffle group 7, and the screen section 4 is prevented from being overturned unintentionally.

Preferably, the set of stops 7 comprises two telescopic stops, one on each side of the axis of rotation 5. In the actual implementation process, when the overturning starts, the telescopic stop block is contracted, and the driving motor drives the screen segment 4 to overturn; when the overturning is finished, the telescopic stop block extends out to support the screen segment 4; the screen mesh layer 3 is prevented from overturning during screening of the wood chips; the screening device is more stable.

Preferably, the retractable stopper includes a stopper for limiting the mesh layer 3, and a second driving means for driving the stopper to be inserted into or removed from the case body 2. In actual implementation, the second driving device drives the cylinder including driving, through driving the cylinder, makes the stopper stretch out or shrink, and then makes things convenient for the upset of screen cloth layer 3.

Preferably, the screen box 1 further comprises a second side wall 8 and a third side wall 9 connected between the two first side walls 6; the third side wall 9 comprises a discharge opening 10 for the wood chips; the mesh layer 3 is gradually inclined downwards from the second side wall 8 to the third side wall 9. In practical implementation, in order to enable the screen layer 3 to adequately screen the wood chips, the wood chips should travel along the screen layer 3 to the discharge outlet as much as possible, and the distance between the second side wall 8 and the third side wall 9 is greater than the distance between the two first side walls 6; the screen layer 3 is connected in the box main body 2, and the screen layer 3 is obliquely arranged, so that the wood chips move forward to the discharge port 10 under the action of gravity in the swinging process of the screen box 1 and are discharged from the discharge port 10. The screen section 4 comprises a screen and a carrier for carrying the screen, on which carrier the rotary shaft 5 is arranged.
