Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] Please see Figures 1-4 An adjustable crushing and screening device includes a cone crusher 1 and a load-bearing support frame 2. The load-bearing support frame 2 is installed on the lower wall of the cone crusher 1. Two load-bearing fixed frames 3 are installed on the outer wall of the load-bearing support frame 2. A height adjustment structure is installed on the outer wall of the load-bearing fixed frame 3. A distribution adjustment structure is installed on the inner wall of the load-bearing fixed frame 3. A screening structure is connected to the distribution adjustment structure. A screening adjustment structure is installed on the screening structure. The height adjustment structure includes: two side wall load-bearing frames 4, two load-bearing push rods 5, and four load-bearing hydraulic cylinders 6. The two side wall load-bearing frames 4 are respectively installed on the two sides of the two load-bearing fixed frames 3. The two load-bearing push rods 5 are respectively installed on the lower wall of the two side wall load-bearing frames 4. The four load-bearing hydraulic cylinders 6 are respectively fitted on the outer wall of the two load-bearing push rods 5.
[0022] Please see Figure 3The distribution and adjustment structure includes: a load-bearing rotating shaft 7, an adjustment guide plate 8, two first distribution hydraulic cylinders 9, and two second distribution hydraulic cylinders 10; the load-bearing rotating shaft 7 is installed inside the two side wall load-bearing frames 4, the adjustment guide plate 8 is fitted on the outer wall surface of the load-bearing rotating shaft 7, the two first distribution hydraulic cylinders 9 are respectively hinged to the left end face of the adjustment guide plate 8, and the two second distribution hydraulic cylinders 10 are respectively hinged to the right end face of the adjustment guide plate 8.
[0023] Please see Figure 4 The screening structure includes: a screening fixing frame 11, two sets of screening hydraulic cylinders 12, two sets of hydraulic push rods 13, and two screening frames 14; the screening fixing frame 11 is installed on the lower wall of two first distribution hydraulic cylinders 9 and two second distribution hydraulic cylinders 10, the two sets of screening hydraulic cylinders 12 are respectively installed on the two sides of the screening fixing frame 11, the two sets of hydraulic push rods 13 are respectively connected inside the two sets of screening hydraulic cylinders 12, and the two screening frames 14 are respectively connected to the outer end face of the two sets of hydraulic push rods 13.
[0024] Please see Figure 4 The screening adjustment structure includes: two screening shafts 15, several spring connecting pins 16, several support springs 17, and four sets of displacement sensors 18; the two screening shafts 15 are respectively installed on the inner wall of the two screening frames 14, the several spring connecting pins 16 are respectively installed between the screening fixed frame 11 and the two screening frames 14, the several support springs 17 are respectively fitted between the several spring connecting pins 16, and the four sets of displacement sensors 18 are respectively installed between the screening fixed frame 11 and the two screening frames 14.
[0025] Please see Figure 1 Two first conveyor belts 19 and two second conveyor belts 20 are installed inside the two side wall support frames 4. When in use, the crushed material is screened by the action of the vibration motor 22. The finer material falls onto the second conveyor belt 20 below along the screening frame 14 and is conveyed out. The screening frame 14 is tilted so that the larger pieces of crushed material inside are poured onto the corresponding first conveyor belt 19 and conveyed out.
[0026] Please see Figure 3 Four damping rods 21 are hinged between the two screening frames 14 and the screening fixing frame 11. When the hydraulic push rod 13 is reset during use, several support springs 17 drive the screening frame 14 to press against the hydraulic push rod 13 again, and the damping rods 21 enhance stability.
[0027] Please see Figure 4 Vibration motors 22 are installed on the lower walls of the two screening frames 14. When in use, the material falls onto the left screening frame 14 along the adjusting guide plate 8, and the crushed material is screened under the action of the vibration motor 22.
[0028] Example 1: In this example, by activating four load-bearing hydraulic cylinders 6, two load-bearing push rods 5 drive two side wall load-bearing frames 4 to adjust up and down as needed. The two side wall load-bearing frames 4 together drive the load-bearing fixed frame 3 to move, and the cone crusher 1 adjusts its height according to the load-bearing fixed frame 3.
[0029] Specifically, the operator can activate four load-bearing hydraulic cylinders 6, and through two load-bearing push rods 5, drive the two side wall load-bearing frames 4 to adjust up and down as needed. The two side wall load-bearing frames 4 together drive the load-bearing fixed frame 3 to move, and the cone crusher 1 adjusts its height according to the load-bearing fixed frame 3. At this time, the operator can put the material into the cone crusher 1 for crushing.
[0030] In Example 2, in this example, the displacement sensor 18 controls a set of screening hydraulic cylinders 12 on the left to extend the corresponding hydraulic push rods 13 while the two first distribution hydraulic cylinders 9 extend and the two second distribution hydraulic cylinders 10 retract, so that the adjusting guide plate 8 rotates in the opposite direction around the load-bearing rotating shaft 7, so that the two screening frames 14 work alternately.
[0031] Specifically, initially, the two first distribution hydraulic cylinders 9 retract, and the two second distribution hydraulic cylinders 10 extend, causing the adjusting guide plate 8 to rotate around the load-bearing shaft 7 at a certain angle. When the crushed material falls onto the adjusting guide plate 8 along the cone crusher 1, it falls onto the left screening frame 14. Under the action of the vibrating motor 22, the crushed material is screened. The finer material falls onto the second conveyor belt 20 below the screening frame 14 and is conveyed out. Larger pieces of crushed material remain on the screening frame 14. When the large pieces of crushed material accumulate to a certain extent on the screening frame 14, the weight increases, and the distance between the two sets of displacement sensors 18 shortens accordingly. The corresponding support springs 17 retract. When the distance shortens to a certain extent, the displacement sensors 18 control the left set of screening hydraulic cylinders 12 to drive the corresponding hydraulic pushers. When rod 13 extends, it pushes the corresponding screening frame 14 around the left screening shaft 15, causing the screening frame 14 to tilt and pour the large pieces of crushed material inside onto the corresponding first conveyor belt 19 for conveying. During this process, several support springs 17 automatically adjust, and the hinged damping rod 21 extends and retracts accordingly. When the hydraulic push rod 13 returns to its original position, several support springs 17 drive the screening frame 14 to press against the hydraulic push rod 13 again, and the damping rod 21 enhances stability. The displacement sensor 18 controls a set of screening hydraulic cylinders 12 on the left to extend the corresponding hydraulic push rod 13. At the same time, the two first distribution hydraulic cylinders 9 extend, and the two second distribution hydraulic cylinders 10 retract, causing the adjusting guide plate 8 to rotate in the opposite direction around the load-bearing shaft 7. At this time, the crushed material falls onto the right screening frame 14. The cycle described above is repeated to achieve the alternating operation of the two screening frames 14.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
