The mounting barrel is disposed on the support legs 110.

The crushing barrel 200 is vertically arranged on the mounting frame 100, specifically, the crushing barrel 200 is fixedly arranged in the mounting barrel, a feed inlet 210 is arranged above the crushing barrel, and a discharge outlet 220 is arranged at the bottom of the crushing barrel. The crushed material is discharged from the discharge port 220 of the crushing barrel 200 and then discharged from the discharge port 120. The inner wall of the crushing barrel 200 is provided with a plurality of ring grooves 230, the ring grooves 230 are coaxial with the crushing barrel 200, and the opening direction of the ring grooves 230 faces the axle center of the crushing barrel 200. The plurality of ring grooves 230 are uniformly distributed in the vertical direction. The drive assembly includes a drive shaft 310, the drive shaft 310 being vertical and rotatably inserted within the crushing drum 200. The drive shaft 310 is provided with a plurality of attachment portions 311, and the attachment portions 311 are annular. The mounting portions 311 are fixedly sleeved on the driving shaft 310, the plurality of mounting portions 311 are uniformly distributed along the vertical direction, and the diameter of the mounting portions 311 is larger than that of the driving shaft 310.

The filter screen can be sleeved with the mounting part 311 in a vertically sliding manner, and the circumferential edge of the filter screen is inserted into the ring groove 230, so that the filter screen can move up and down within the wide range of the ring groove 230. Each filter screen contacts with the peripheral wall of one mounting portion 311, and when the filter screen slides down, the filter screen is separated from the corresponding mounting portion 311, so that a gap is generated between the filter screen and the driving shaft 310, and broken materials can drop down from the gap between the filter screen and the driving shaft 310. A plurality of first springs 231 are arranged between the filter screen and the ring groove 230, the plurality of first springs 231 are uniformly distributed in the ring groove 230 in the circumferential direction, the first springs 231 are vertically arranged, the upper end of each first spring is fixedly connected with the circumferential edge of the filter screen, and the lower end of each first spring is fixedly connected with the bottom of the ring groove 230, so that the first springs 231 are compressed to store force when the filter screen moves downwards. The diameters of the filter holes of the filter screens are sequentially reduced from top to bottom.

The crushing assembly includes a plurality of first crushing groups and a plurality of second crushing groups. Each first crushing group is positioned above one filter screen. The first crushing group includes a crushing plate 510, the crushing plate 510 is vertically disposed, and one end is connected with an inner wall of the crushing tub 200, specifically, a projection of the vertical direction of the crushing plate 510 extends along a radial direction of the crushing tub 200, and the other end of the crushing plate 510 is in clearance fit with the driving shaft 310. Each second crushing group is located above one filter screen, the second crushing group comprising a fly plate 520. One end of the fly plate 520 is fixedly coupled to the driving shaft 310, and is disposed at a higher inclination in the rear side than in the front side in the rotation direction of the driving shaft 310. The angle at which the fly plates 520 on the second crushing group are inclined becomes gradually smaller from top to bottom. The edge of the lower side of the inclined position of the striking plate 520 contacts with the surface of the filter screen below the lower side of the inclined position of the striking plate, so that when the striking plate 520 rotates along with the driving shaft 310, the material on the filter screen can be shoveled up to achieve the effect of striking, and the material can collide with the crushing plate 510 under the action of inertia, so that the crushing of the material is completed. Further, when the material is jammed between the strike plate 520 and the filter screen, the filter screen is pressed downward, so that the filter screen moves downward below the mounting portion 311. Gaps are formed between the filter screen and the flying plate 520, and the gaps are increased along with the downward movement of the filter screen, so that the flying plate 520 and the filter screen are released from a blocking state, and the crushing efficiency of the device is improved.

In this embodiment, as shown in fig. 3 to 13, the plurality of filter screens includes a first filter screen 410, a second filter screen 420, and a third filter screen 430.

The second filter 420 is provided with a plurality of shielding plates 421, and the shielding plates 421 are in a screen shape and have the same screen mesh structure as the second filter 420. The shielding plate 421 is in a fan-shaped plate shape, and a plurality of shielding plates 421 are uniformly distributed on the second filter screen 420. The shielding plate 421 can be arranged in a sliding manner along the radial direction of the second filter screen 420, the surfaces of the shielding plate 421 and the second filter screen 420 are attached, the filtering holes in the shielding plate 421 are partially overlapped with the filtering holes in the second filter screen 420, the size of the overlapped part area is positively correlated with the sliding distance of the shielding plate 421 towards the driving shaft direction, the overlapped part of the filtering holes in the shielding plate 421 and the second filter screen 420 is the effective filtering diameter of the second filter screen 420, when the partial overlapped area between the shielding plate 421 and the second filter screen 420 is larger, the effective filtering diameter on the second filter screen 420 is larger, the maximum diameter of the filtered material is larger, so that the filtering speed of the material can be increased, and the accumulation of the material on the second filter screen 420 is prevented. Further, the initial state of the effective filter diameter of the second filter 420 is smaller to prevent excessive material from flowing down to the third filter 430, so as to prevent the third filter 430 from accumulating material. When the shielding plate 421 slides along the second filter screen 420 toward the driving shaft 310 by a predetermined distance, the axes of the filter holes on the shielding plate 421 and the axes of the filter holes on the second filter screen 420 are aligned, and the effective filter diameter of the second filter screen 420 is maximized when the filter holes between the two are aligned. A plurality of linkage assemblies are arranged in the ring groove 230 corresponding to the second filter screen 420, and each linkage assembly is connected with one shielding plate 421; the linkage assembly is used for driving the shielding plate 421 to slide along the radial direction of the second filter screen 420 when the second filter screen 420 moves downwards, so that the overlapping portion between the filtering holes of the shielding plate 421 and the filtering holes of the second filter plate gradually increases.

In this embodiment, as shown in fig. 7 to 15, the linkage assembly includes a push rod 423, a push block 424, and a second spring 425. A plurality of sliding grooves 422 are uniformly distributed on the circumferential edge of the second filter screen 420; the sliding groove 422 extends in the radial direction of the second filter screen 420; the arc edge of the shielding plate 421 is provided with a protruding block which can be inserted into the sliding groove 422; the push block 424 is slidably disposed in the sliding groove 422, and an end of the push block 424 near the driving shaft 310 contacts the bump. The second spring 425 is disposed in the sliding groove 422 and connected to the push block 424, so that when the push block 424 slides toward the driving shaft 310, the second spring 425 is compressed and accumulated, and the second spring 425 is disposed to enable the push block 424 to shift relative to the shielding plate 421 and restore to the initial position. The ejector pin 423 is vertically disposed in the ring groove 230, and the upper end of the ejector pin 423 contacts with the ejector pin 424, so that when the ejector pin 424 moves downward relative to the ejector pin 423, the ejector pin 423 pushes the ejector pin 424 to slide toward the driving shaft 310, specifically, a first inclined surface 4241 is disposed at one end of the ejector pin 424 away from the shielding plate 421, and the first inclined surface 4241 can convert the vertical pushing force received by the ejector pin 424 into a horizontal pushing force, so that the ejector pin 423 pushes the ejector pin 424 to move horizontally.

In this embodiment, as shown in fig. 11 to 14, a clearance groove is provided in the second filter 420, and the shielding plate 421 is slidably inserted into the clearance groove. The shielding plate 421 is internally provided with a plurality of third springs 426, one end of each third spring 426 is connected with one end of the clearance groove close to the driving shaft 310, the other end of each third spring 426 is connected with one end of the shielding plate 421 close to the driving shaft 310, when the shielding plate 421 slides towards the driving shaft 310, the third springs 426 are compressed to store force, and when the third springs 426 are restored, the shielding plate 421 is driven to restore to the initial position.

In this embodiment, as shown in fig. 3 to 6, the filter screen is funnel-shaped, and the circumferential edge of the filter screen extends into the ring groove 230 in the horizontal direction, and specifically, the sliding groove 422 is disposed on the horizontal portion of the circumferential edge on the second filter screen 420. The first filter screen 410, the second filter screen 420 and the third filter screen 430 are all funnel-shaped, so that materials can be gathered in the middle of the filter screens, and the material can be conveniently hit by the hit plate 520. Further, when the filter screen slides down to the lower side of the mounting portion 311, the gap between the filter screen and the driving shaft 310 enables the material to be rapidly discharged down onto the lower filter screen, thereby alleviating the accumulation of the material on the filter screen. In particular, a second inclined surface 4242 is provided at an end of the push block 424 contacting with the protruding block of the shielding plate 421, and the second inclined surface 4242 contacts with the push block 424 of the shielding plate 421, and the second inclined surface 4242 of the push block 424 can convert the horizontal thrust into the inclined thrust, so that the shielding plate 421 moves in the gap groove to one side of the driving shaft 310 along the inclined direction.

In this embodiment, as shown in fig. 4 to 8, a plurality of positioning rods 232 are disposed in each ring groove 230. The locating rod 232 is fixedly arranged in the ring groove 230 in the vertical direction, the locating rod 232 can penetrate through the circumferential edge of the corresponding filter screen in the vertical direction, and the locating rod 232 can limit the filter screen to rotate, so that the filter screen can only move up and down in the vertical direction. The positioning rods 232 are circumferentially and uniformly distributed in the ring groove 230.

In this embodiment, as shown in fig. 1 to 3, the driving assembly includes a driving motor 320; the driving motor 320 is fixedly disposed on the mounting frame 100, and an output shaft of the driving motor 320 is connected to the driving shaft 310, so as to drive the driving shaft 310 to rotate when the driving motor 320 is started.

In this embodiment, as shown in fig. 3 to 10, the first crushing group includes a plurality of crushing plates 510; a plurality of crushing plates 510 are uniformly distributed along the circumference of the crushing barrel 200; the number of the fly plates 520 included in each second crushing group is plural; the plurality of fly plates 520 are uniformly distributed along the circumference of the driving shaft 310. The arrangement of the plurality of crushing plates 510 and the plurality of fly plates 520 can improve the crushing efficiency of the device on the material.

In this embodiment, as shown in fig. 6 to 9, a swing groove 240 is provided on the inner wall of the crushing barrel 200; a rotatable rotating rod 241 is arranged in the swinging groove 240, and the rotating rod 241 is vertically arranged; the vertical edge of the crushing plate 510 on the side far away from the driving shaft 310 is fixedly connected with the rotating rod 241, so that the crushing plate 510 can swing around the rotating rod 241 as an axis. The both sides of breaker plate 510 all are equipped with a fourth spring 242, and fourth spring 242 is located the swinging tank 240, and one end is connected with the swinging tank 240, and the other end is connected with breaker plate 510, and the setting of fourth spring 242 plays the cushioning effect to breaker plate 510 when the material striking breaker plate 510 is broken, and then prevents that breaker plate 510 receives the too big deformation that produces of stress. In particular, the breaker plate 510 is a right-angled trapezoidal plate, and the beveled edge of the breaker plate 510 is positioned below the breaker plate 510 and parallel to the incline of the filter screen.

In operation, the driving motor 320 is started, the driving motor 320 drives the driving shaft 310 to rotate, and the driving shaft 310 drives the fly-striking plate 520 to rotate synchronously.

The material to be crushed is introduced into the crushing barrel 200 through the feed inlet 210, and the material falls onto the first filter screen 410, and the material is hit by the hit plate 520 on the first filter screen 410 in the rotation process. The material flown by the strike plate 520 has a large inertia so that the material collides with the crushing plate 510 to crush the material. The crushing plate 510 collides with the material to crush the material, and the material is continuously crushed under the cooperation of the impact plate 520 and the crushing plate 510. At the same time, the material is screened through the first screen 410 and the material with acceptable particle size is screened down onto the second screen 420.

When the material is located between the filter screen and the flier 520, the flier 520 is prevented from rotating, and is blocked, and the flier 520 has downward extrusion force on the filter screen through the material below the flier 520. When the downward extrusion force of the filter screen reaches a preset value, the filter screen moves downwards, a gap is generated between the filter screen and the flying plate 520, and the gap between the filter screen and the flying plate is gradually increased along with the increase of the downward movement amount of the filter screen, so that the pressure of the filter screen and the flying plate 520 on the blocked materials disappears, the blocked materials slide out of the space between the filter screen and the flying plate 520 along the inclined plane of the filter screen, and the blocked state of the flying plate 520 is relieved.

When the filter screen moves to below the mounting portion 311, a gap exists between the filter screen and the driving shaft 310, so that a part of the material flows from the gap between the filter screen and the driving shaft 310 to the lower filter screen to continue filtering. Meanwhile, the clamped material can also flow to the lower filter screen through the gap between the filter screen and the driving shaft 310.

When the second filter screen 420 moves downwards, the ejector rod 423 pushes the push block 424 to move towards the driving shaft 310 through the first inclined surface 4241 of the push block 424, and the push block 424 pushes the shielding plate 421 to move towards the driving shaft 310 through the second inclined surface 4242, so that the overlapping part of the filtering holes of the shielding plate 421 and the filtering holes of the second filter screen 420 is gradually increased, the effective filtering diameter on the second filter screen 420 is increased, and the maximum diameter of the filtered material is increased, so that the filtering speed of the second filter screen 420 on the material can be increased, and the accumulation of the material on the second filter screen 420 is prevented.

The filtered material is discharged from the discharge port 220 of the crushing barrel 200 after being filtered step by step and crushed by the first filter screen 410, the second filter screen 420 and the third filter screen 430, and is discharged and collected from the discharge port 120.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
