[0015] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0016] Specific embodiments: As shown in Figures 1-4 FIG. 5, a support assembly of a composite vibrating screen includes a support 1. On both sides of the front and rear parts of the support 1, a front support column 12 and a rear support column 11 are respectively arranged. Inside the front support column 12, a front rotating shaft 171 is arranged. Inside the rear support column 11, a rear rotating shaft 13 is arranged. The front rotating shaft 171 and the rear rotating shaft 13 are both parallel to the width direction of the sieve box 2 and perpendicular to the length direction of the sieve box 2. A vibrating motor is arranged on the sieve box 2 to enable it to move left and right and back and forth. It also includes four suspension assemblies 14. The suspension assembly 14 includes a first connecting rod 141 and a second connecting rod 142. At the upper and lower ends of the first connecting rod 141, a first shaft hole and a second shaft hole perpendicular to each other are respectively arranged. At the upper and lower ends of the second connecting rod 142, a third shaft hole and a fourth shaft hole perpendicular to each other are respectively arranged. In order to reduce friction, bearings are arranged in the first shaft hole, the second shaft hole, the third shaft hole and the fourth shaft hole. The second shaft hole and the third shaft hole can be rotatably connected through a pin shaft. The two front rotating shafts 171 and the two rear rotating shafts 13 are respectively rotatably connected to the first shaft holes on the four suspension assemblies 14. A total of four side rotating shafts arranged on both sides of the front and rear ends of the sieve box 2 are respectively rotatably connected to the four fourth shaft holes. The suspension assembly 14 allows the sieve box 2 to move in the front and rear directions and the left and right directions at the same time. Compared with steel wire ropes, the suspension assembly 14 is not easily damaged and has a longer service life.

[0017] In this embodiment, a top plate 121 is arranged at the top end of the front support column 12. A guide groove 122 penetrating its upper and lower surfaces is arranged on the top plate 121. The extending direction of the guide groove 122 is parallel to the length direction of the sieve box 2. A translation block 16 is slidably connected in the guide groove 122. The translation block 16 is threadedly connected with a screw rod 15. The lower end of the screw rod 15 is rotatably connected with a lifting block 17. The lifting block 17 is slidably connected with the front support column 12. The front rotating shaft 171 is arranged inside the lifting block 17. By rotating the screw rod 15, the inclination angle of the sieve box 2 can be adjusted. When adjusting the inclination angle of the sieve box 2, in order to make the force in the front and rear directions received by the sieve box 2 in the natural state smaller or even not receive the force in the front and rear directions (so as to have less influence on the vibration of the sieve box 2), the position of the translation block 16 can be adjusted so that the suspension assembly 14 is in a vertical state.

[0018] In this embodiment, the cross-section of the guide groove 122 is T-shaped, and the cross-section of the translation block 16 is also T-shaped, and the two cooperate with each other.

[0019] In this embodiment, a handwheel is provided at the upper end of the screw rod 15 to facilitate the rotation of the screw rod 15.
