Fig. 4 is a schematic perspective view of a box body used in a screening device with a blocking removal function according to an embodiment of the present application.

The embodiment of the application provides a screening plant with clear stifled function, as shown in fig. 1, fig. 2 and fig. 3, including box 100, pivot 200, limiting plate 300 and spacing round pin axle 400, wherein box 100 is the container of material screening, and rotation of sieve 220 is realized to pivot 200, and limiting plate 300 and spacing round pin axle 400 realize the fixed to pivot 200, make pivot 200 remain fixed at the in-process of screening.

As shown in fig. 1, the box 100 is provided with a feed inlet and a discharge outlet, and materials can be added into the box 100 from the feed inlet and can be discharged from the discharge outlet after being screened. To facilitate the discharge, the bottom of the case 100 is generally in the shape of a bucket, facilitating the falling of the material.

As shown in fig. 1 and 2, the rotation shaft 200 is rotatably coupled to the inside of the case 100 such that a first end of the rotation shaft 200 protrudes out of the first sidewall 110 of the case 100, and generally, the rotation shaft 200 is disposed at an intermediate position of the first sidewall 110.

As shown in fig. 3, the first end of the rotating shaft 200 is provided with two first limiting holes 210 extending in the radial direction, the two first limiting holes 210 are arranged at 180-degree intervals along the circumferential direction of the rotating shaft 200, the rotating shaft 200 is symmetrically provided with two sieve plates 220, and the sieve plates 220 are positioned in the box body 100. The distance between the rotation shaft 200 and the top of the case 100 and the distance between the rotation shaft 200 and the bottom of the case 100 should be greater than the width of the screen plate 220 (about half of the width of the first sidewall 110) so that the screen plate 220 does not collide with the top and bottom of the case 100 when rotated.

It should be noted that, a discharge port is disposed at a position slightly higher than the rotating shaft 200 of the box 100, so as to clean out the material remained on the screen plate 220 after screening is completed.

In order to facilitate rotation of the rotation shaft 200, the screen plate 220 may be slightly contacted with the inner wall of the case 100, and the contact position of the screen plate 220 is set to be arc-shaped, so that rotation is facilitated. A small gap may also exist between the screen plate 220 and the inner wall of the housing 100, which is smaller than the size of the material, i.e. the material does not fall from this gap, so that rotation of the screen plate 220 is also achieved.

As shown in fig. 1 and fig. 4, the limiting plate 300 is mounted on the first side wall 110, the limiting plate 300 is provided with a first through hole 310 and a second limiting hole 320, the first through hole 310 is perpendicular to the first side wall 110, the second limiting hole 320 is parallel to the first side wall 110 and is communicated with the first through hole 310, a first end of the rotating shaft 200 passes through the first through hole 310, when the first limiting hole 210 is opposite to the second limiting hole 320, the screen plate 220 is in a horizontal state, and the limiting pin shaft 400 is inserted into the opposite first limiting hole 210 and second limiting hole 320, so that the rotating shaft 200 can be fixed relative to the limiting plate 300.

When in use, when one first limit hole 210 is opposite to one second limit hole 320, the limit pin 400 is inserted into the first limit hole 210 and the second limit hole 320, so that the rotating shaft 200 is kept fixed, and the screen plate 220 is in a horizontal state, so that the materials can be screened. After screening for a period of time, if screen plate 220 appears blocking, the staff can extract spacing round pin axle 400, and operating spindle 200 rotates 180 degrees, makes another first spacing hole 210 and second spacing hole 320 relative, and screen plate 220 just has turned over 180 degrees like this, then inserts spacing round pin axle 400 again, and when screening like this, the sieve mesh that blocks up can be cleared up to the material, realizes clear stifled function.

Compared with the prior art, the sieve plate 220 of the sieving device can be turned 180 degrees under the action of the rotating shaft 200, so that both sides of the sieve plate 220 can bear the impact of materials. When the condition of blocking appears in one side of the sieve plate 220, the sieve plate can be turned 180 degrees, and the other side can bear the impact of the material, so that the blocked material falls under the conditions of the impact of the material and the vibration of the sieve plate 220, and the blocking is removed. In this process, the screen plate 220 is avoided from being disassembled, and the blocking can be removed only by rotating the rotating shaft 200 by 180 degrees, so that the blocking removing time is greatly reduced, and the screening efficiency is improved.

In some embodiments, as shown in FIG. 1, the first end of the shaft 200 is further provided with a handle 230 to facilitate the rotation of the shaft 200 by an operator. An operator can hold the handle 230 to rotate the rotation shaft 200.

In some embodiments, as shown in fig. 3, the first end of the rotating shaft 200 is provided with a second through hole 240, the handle 230 is slidably connected in the second through hole 240, both ends of the handle 230 are provided with plugs 231, and the plugs 231 prevent the handle 230 from sliding out of the second through hole 240. That is, the handle 230 is movable, so that an operator can adjust the length of the handle 230, and force can be applied conveniently.

In some embodiments, one of the plugs 231 is removably coupled to the handle 230 to facilitate mounting the handle 230 within the second through-hole 240.

In some embodiments, as shown in fig. 4, the limiting plate 300 includes a transverse plate 330 and a vertical plate 340, the transverse plate 330 is vertically mounted on the first side wall 110, the vertical plate 340 is vertically mounted on the transverse plate 330, and the first through hole 310 and the second limiting hole 320 are both disposed on the vertical plate 340. That is, the entire limiting plate 300 is L-shaped, so that the mounting and fixing of the limiting plate 300 and the first sidewall 110 are facilitated.

In some embodiments, as shown in fig. 3, the rotating shaft 200 is provided with a mounting clamping plate 250, and the mounting clamping plate 250 is double-layered, so that the screen plate 220 can be clamped between the mounting clamping plates 250, and the screen plate 220 can be detachably connected to the mounting clamping plate 250, for example, through bolts, screws, and the like. This clamping arrangement allows for the screen 220 to be clamped together and allows for rotation of the screen 220 by means of the mounting clamp 250 when the screen 220 is relatively thin (e.g., the screen 220 is a screen).

In some embodiments, as shown in fig. 3, the installation clamp plate 250 is in a frame shape, and encloses a rectangle with the rotating shaft 200, and the screen is installed at the rectangular position to screen the material.

In some embodiments, as shown in fig. 1, a plurality of supporting legs 120 are provided below the box 100, so that a certain distance is provided between the bottom of the box 100 and the ground, so that a material receiving container is conveniently placed in the bottom of the box 100, and material receiving is convenient.
