[0031] In some embodiments, please refer to the attached instructions. Figure 1-7 , a particle screening device, comprising a linear screening machine housing 1;

[0032] A screen 2 is fixedly installed inside the linear screening machine housing 1, and a plurality of screen holes 21 are evenly opened on the top of the screen 2. An aperture adjustment component 3 for controlling the effective aperture of the screen hole 21 is arranged on the right side of the outer wall of the linear screening machine housing 1;

[0033] A hopper 4 for feeding is fixedly installed on the top rear side of the linear screening machine casing 1, and a feeding mechanism 5 for automatic quantitative feeding is arranged on the hopper 4. The feeding mechanism 5 includes a feeding component 51 for tearing the material bag, a flow regulating component 52 for controlling the material flow, and an opening 53 for discharging the material. The feeding component 51 is arranged at the inner bottom of the hopper 4, the flow regulating component 52 is arranged at the front side of the hopper 4, and the opening 53 is opened at the front side of the inner bottom of the hopper 4.

[0034] The effective aperture refers to the maximum aperture of the sieve 21 that can pass the material;

[0035] When the utility model is in use, a material bag is placed in the hopper 4, at which time the bottom of the material bag is located at the inner bottom of the hopper 4, and the feeding component 51 is controlled to cut the bottom of the material bag to make the material in the material bag flow out, and under the vibration of the linear screening machine case 1, the material is discharged from the opening 53 to the top rear side of the screen 2 by itself, and the flow regulating component 52 is controlled to adjust the size of the opening slot on the front side of the hopper 4, so as to control the flow of the material in the hopper 4, so as to achieve the effect of self-control of material falling and adjustable flow, and the aperture regulating component 3 is controlled to adjust the effective aperture of the sieve hole 21, so that the sieve hole 21 can screen particles of different sizes, and has high applicability.

[0036] The feeding assembly 51 includes a sliding rod 511 and a cutter 512. The sliding rod 511 is limitedly slidably connected to the top rear side of the linear screening machine housing 1. The cutter 512 is fixedly connected to the top left side of the sliding rod 511. When the material bag is placed in the hopper 4, the cutter 512 is located at the bottom left end of the material bag.

[0037] The flow regulating assembly 52 includes a U-shaped plate 521 and a lifting assembly 522. The U-shaped plate 521 is limitedly slidably connected to the front side of the outer wall of the hopper 4. The front side of the outer wall of the hopper 4 is provided with a lifting assembly 522. The hopper 4 is movably connected to the U-shaped plate 521 through the lifting assembly 522.

[0038] An open groove is provided on the front side of the outer wall of the hopper 4, and the U-shaped groove of the U-shaped plate 521 is limitedly slidably connected with the two side walls at the top of the open groove;

[0039] The lifting assembly 522 includes a fixed block 5221, a moving block 5222 and a screw 5223. The fixed block 5221 is fixedly connected to the upper front part of the outer wall of the hopper 4, and the moving block 5222 is fixedly connected to the front side of the outer wall of the U-shaped plate 521. The fixed block 5221 is rotatably connected to the screw 5223, and the screw 5223 is threadedly connected to the moving block 5222.

[0040] When the material bag is put into the hopper 4, the cutter 512 is located at the bottom left of the material bag, and the sliding rod 511 is pulled to drive the cutter 512 to move. When moving, the cutter 512 will scratch the bottom of the material bag to cause the material to leak out. Under the vibration of the linear screening machine chassis 1, the material moves to the opening slot of the hopper 4 with the vibration and falls on the rear top of the screen 2, thereby realizing the self-feeding of the material. By controlling the rotation of the screw 5223, the moving block 5222 is driven to move toward the fixed block 5221, thereby increasing the height of the opening slot of the hopper 4, so that the speed of the self-flow of the material in the hopper 4 is increased, thereby increasing the material flow rate of the hopper 4. Similarly, the material flow rate of the hopper 4 is reduced, thereby realizing the control of the material flow rate in the hopper 4, which is convenient for controlling the flow rate.

[0041] The aperture adjustment component 3 includes a moving component 31 and a covering component 32. The moving component 31 is arranged on the right side of the outer wall of the linear screening machine housing 1, and the covering component 32 is arranged inside the screen 2. The moving component 31 is movably connected with the covering component 32.

[0042] The moving assembly 31 includes a screw block 311 and a threaded rod 312. A screw seat is fixedly connected to the right side of the outer wall of the linear screening machine housing 1. The threaded rod 312 is rotatably connected to the screw seat. The screw block 311 is threadedly connected to the threaded rod 312.

[0043] The covering assembly 32 includes a straight plate 321 and a semicircular hole plate 322. A movable groove is opened on the right side of the outer wall of the screen 2. The straight plate 321 and the semicircular hole plate 322 are limitedly slidably connected in the movable groove. The left end of the screw block 311 is fixedly connected to the right end of the straight plate 321. A plurality of semicircular hole plates 322 are fixedly connected to the left side of the outer wall of the straight plate 321. There are a plurality of semicircular hole plates 322 evenly distributed along the straight line direction.

[0044] The threaded rod 312 is controlled to rotate to drive the screw block 311 to move, and the movement of the screw block 311 drives the straight plate 321 to move. When the straight plate 321 moves, it drives the semicircular hole plate 322 to move. The semicircular notch of the semicircular hole plate 322 overlaps with the area of ​​the sieve hole 21, thereby covering part of the area of ​​the sieve hole 21. Some particles with a diameter larger than the aperture after covering will be intercepted and retained on the sieve 2, thereby achieving filtering effects of different sizes.
