[0036] Please refer to Figure 1-Figure 4 A crusher with screening function includes a casing 1, two crushing plates 2, two crushing rollers 3, two driving mechanisms 4, an impact plate 5, a screening mechanism 6, a guide plate 9, two connecting plates 8 and two telescopic rods 7.

[0037] like Figure 1 As shown, the casing 1 has a cavity 1a inside, a feed port 1b is provided on the top of the casing 1, and two discharge ports 1c are provided on the bottom. Materials enter the cavity 1a through the feed port 1b, and after being crushed, they fall out from the discharge ports 1c.

[0038] like Figure 1 As shown, two crushing plates 2 are arranged in the cavity 1a, and their facing surfaces have serrations. Two crushing rollers 3 are rotatably arranged in the cavity 1a, and a plurality of crushing blades are provided on the circumferential surface of the crushing rollers 3. When the material enters the cavity 1a through the feed port 1b, the two driving mechanisms 4 drive the two crushing rollers 3 to rotate in opposite directions, and cooperate with the crushing plates 2 to crush the material.

[0039] The guide plate 9 is triangular in shape, arranged in the cavity 1a, and located between the feed port 1b and the two crushing rollers 3; the material falls into the cavity 1a through the feed port 1b, and is divided into two streams by the guide plate 9, so that the material falls between the crushing roller 3 and the crushing plate 2 respectively, so that the crushing roller 3 and the crushing plate 2 can crush the material.

[0040] The impact plate 5 is arranged at the inner bottom of the casing 1 and is located between the two discharge ports 1c; the particles between the crushing roller 3 and the crushing plate 2 splash onto the impact plate 5 and are further crushed.

[0041] Specifically, Figure 4 As shown, the driving mechanism 4 includes a motor 41, two pulleys 42 and a belt 43; one end of the crushing roller 3 extends outside the casing 1 and is connected to one of the pulleys 42, the output shaft of the motor 41 is connected to the other pulley 42, and the belt 43 is sleeved on the two pulleys 42; one of the pulleys 42 is driven to rotate by the motor 41, and then driven by the belt 43, the other pulley 42 drives the crushing roller 3 to rotate, so that the two crushing rollers 3 rotate in opposite directions.

[0042] like Figure 1 and Figure 2As shown, two storage troughs 1d are also provided at the inner bottom of the casing 1, and the screening mechanism 6 is arranged at the discharge port 1c, and the storage trough has an opening connected to the screening mechanism 6; the connecting plate 8 is rotatably arranged at the opening, and the two ends of the telescopic rod 7 are respectively hinged to the casing 1 and the connecting plate 8; the particles impacted by the impact plate 5 fall into the storage trough, and the connecting plate 8 is driven to rotate downward by the telescopic rod 7, so that the particles fall through the opening onto the screening mechanism 6, so that the screening mechanism 6 can screen the particles.

[0043] Specifically, Figure 1 and Figure 4 As shown, the screening mechanism 6 includes a screening plate 61, an eccentric motor 62 and a guide plate 63; the screening plate 61 is arranged at the discharge port 1c; a plurality of through holes 61a are provided on the screening plate 61, and the diameter of the through holes 61a gradually decreases from close to the storage tank 1d to away from the storage tank 1d; the eccentric motor 62 is arranged on the outer wall of the casing 1, and the eccentric wheel of its output shaft abuts against the bottom of the screening plate 61, and the guide plate 63 is located directly below the screening plate 61 and has a plurality of inclined diversion channels 63a; the connecting plate 8 is opened, and the particles fall onto the screening plate 61 through the opening, and the eccentric motor 62 drives the screening plate 61 to vibrate, so that the particles pass through the through holes 61a from small to large in turn, and fall into different diversion channels 63a on the guide plate 63 according to a certain range, and the particles are screened through the diversion channels 63a.

[0044] The screen plate 61 is flexibly connected to the discharge port 1c; for example, a corrugated plate made of rubber is provided between the screen plate 61 and the discharge port 1c. This arrangement is because when the screen plate 61 vibrates, if the screen plate 61 is rigidly connected to the casing 1, the casing 1 will vibrate together. Therefore, the screen plate 61 is flexibly connected to the casing 1 to reduce the vibration of the casing 1.

[0045] The working principle of this embodiment is:

[0046] The material enters the cavity 1a through the feed port 1b, and the two crushing rollers 3 rotate in opposite directions and cooperate with the crushing plate 2 to crush the material; the crushed particles collide with the impact plate 5 for further crushing, and finally fall into the storage tank 1d; when the opening is opened, the particles in the storage tank 1d fall onto the screening mechanism 6, and the screening mechanism 6 screens the particles according to their size.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
