DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 to Figure 5 In the embodiment of the utility model, a granulator with screening function comprises a granulator body 1 and a silo 2 equipped with a screening assembly, the screening assembly comprises a feed hopper 3 connected to the silo 2 by a hinge, a screen 4 is installed in the middle of the feed hopper 3, a crushing bin 5 connected to the feed hopper 3 is installed on the outer wall of the feed hopper 3, and the feed hopper 3 is rotated ninety degrees by the hinge. The material on the screen 4 enters the crushing bin 5, and a crushing assembly for crushing the material that cannot pass through the screen 4 is installed on the outer side of the crushing bin 5, and a push-pull assembly for dispersing the material is provided on the screen 4. The crushing assembly comprises two crushing rollers 6 installed inside the crushing bin 5, and a connecting port 7 connected to the feed hopper 3 is opened on the side wall of the feed hopper 3. A storage bin 8 for temporarily storing the crushed material is provided inside the crushing bin 5, and a positioning frame 11 is provided on one side of the silo 2 to prevent the feed hopper 3 from rotating at an excessive angle.

[0023] The feed hopper 3 is connected to the silo 2 by a hinge, and the connection between the feed hopper 3 and the silo 2 is sealed by a rubber pad. The other end of the feed hopper 3 and the silo 2 are connected and fixed by an adjustable buckle. After the feed hopper 3 and the silo 2 are fixed, the material can be put onto the screen 4 for screening. After the feed hopper 3 is rotated ninety degrees, the larger material on the screen 4 can enter the crushing bin 5 through the connecting port 7 for crushing. After the material in the crushing bin 5 is completely crushed by the two crushing rollers 6, the feed hopper 3 is re-fixed to the top of the silo 2, and the crushed material in the crushing bin 5 will enter the screen 4 again for re-screening. Excessive material can be temporarily stored in the storage bin 8. The positioning frame 11 can prevent the feed hopper 3 from rotating too much and prevent the material from scattering to the outside of the feed hopper 3.

[0024] In one embodiment, specifically, the connecting port 7 is provided with a guide plate 9 for conveying large particle materials between the two crushing rollers 6, one end of the guide plate 9 extends between the two crushing rollers 6, and the connecting axis of the guide plate 9 is located on the side away from the screen 4. A limit block 10 for preventing the guide plate 9 from rotating too much is installed inside the connecting port 7. The guide plate 9 can facilitate the material on the screen 4 to enter between the two crushing rollers 6. When the feed hopper 3 turns back to the silo 2, the material can push the guide plate 9 away and enter the screen 4 again. The limit block 10 can prevent the guide plate 9 from rotating too much and getting stuck on the crushing roller 6.

[0025] Among them, a fixing frame 12 is installed at the bottom of the screen 4, and a mounting frame 13 is provided on the top of the screen 4. The fixing frame 12 and the mounting frame 13 are connected by bolts. The screen 4 is located between the fixing frame 12 and the mounting frame 13. The screen 4 is installed from the bottom of the mounting frame 13 to the inside of the feed hopper 3, and the mounting frame 13 is fixed inside the feed hopper 3. The fixing frame 12 is fixed to the mounting frame 13 by bolts, and the screen 4 is clamped between the fixing frame 12 and the mounting frame 13 to facilitate the installation of the screen 4.

[0026] On the basis of the above embodiments, specifically, the push-pull assembly includes a plurality of push plates 14 arranged at equal intervals, and pull rods 15 are respectively connected to both ends of the push plates 14, and the bottom ends of the push plates 14 are in contact with the screen 4. A turntable 16 is installed on the outer side of the feed hopper 3, and a slide groove 17 is provided on the side wall of the feed hopper 3, and a slider 18 is provided on the slide groove 17. The slider 18 is connected to the turntable 16 through two mutually hinged support plates 20, and the support plate 20 is hinged at the eccentric position of the turntable 16. A plurality of equally spaced push plates 14 can move synchronously. During this process, the material will be pushed back and forth by the push plates 14, and the fine material will fall into the lower silo 2 through the holes on the screen 4. The turntable 16 can be driven by a motor. The rotation of the turntable 16 can make the two support plates 20 drive the slider 18 to reciprocate, thereby driving the plurality of push plates 14 to reciprocate.

[0027] When fixing the monitor body 11, first fix the feed hopper 3 above the silo 2, then put the material into the feed hopper 3, and drive the turntable 16 to rotate through the motor. The turntable 16 drives the slider 18 to reciprocate on the slide 17 through the two support plates 20. In this process, fine materials will fall into the silo 2, and larger materials will flow above the screen 4. When no material falls from the screen 4, the entire feed hopper 3 is rotated ninety degrees around the hinge until it is placed on the positioning frame 11. In this process, the large particles on the screen 4 will enter the crushing bin 5 through the connecting port 7 and be crushed by the two crushing rollers 6. The crushed small particles will enter the inside of the crushing bin 5. When the large particles are completely crushed, move the feed hopper 3 back to its original position. In this process, the crushed materials will enter the screen 4 again through the bottom of the guide plate 9 until the materials are completely in the silo 2.

[0028] In one embodiment, specifically, a cover plate 19 for shielding the chute 17 is installed on one side of the slider 18 located inside the feed hopper 3. The cover plate 19 can prevent materials from scattering from the chute 17, thereby reducing material waste.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
