The driven gear and the support gears are rotatably connected to the mounting frame. The other end of the drum screen is provided with a rolling support, which is mounted on the mounting frame.

[0014] Furthermore, the rolling support includes a limiting wheel and a support wheel respectively disposed on both sides and the bottom of the other end of the drum screen, and the limiting wheel and the support wheel are rotatably connected to the mounting frame.

[0015] Furthermore, the end of the drum screen is provided with a groove arranged in a ring, and the edges of the limiting wheel and the support wheel extend into the groove and contact and cooperate with it.

Detailed Implementation

[0023] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

The ends of the adjusting rods 3 on the same side are all hinged to the side wall of the rack 4. The two racks 4 are slidably connected to the two sides of the base frame 1 respectively. A drive mechanism 5 is set on one side of the base frame 1, and the drive mechanism 5 drives the two racks 4 to move horizontally in a linear motion synchronously. A drum screen 6 is rotatably mounted on the installation frame 2 through a drive mechanism 7.

[0025] In this embodiment, both sides of the top of the bottom frame 1 are provided with sliding grooves 101, and the bottom of the rack 4 extends into the corresponding sliding grooves 101 and slides therein; the first drive mechanism 5 is used to drive the two racks 4 to move synchronously in the same direction, and the second drive mechanism 7 is used to drive the drum screen 6 to rotate.

[0026] This scheme uses a drive mechanism 5 to drive two racks 4 to move synchronously in the horizontal direction. Under the action of the adjusting rod 3, the mounting frame 2 can rotate around the hinge point between it and the bottom frame 1. The mounting frame 2 drives the drive mechanism 7 and the drum screen 6 to move synchronously. This allows for the adjustment of the tilt angle of the drum screen 6 according to the specific conditions of the sand and gravel being screened, thus improving its applicability.

[0027] In this embodiment, the drive mechanism 5 includes a drive shaft 51 horizontally disposed between the base frame 1 and the mounting frame 2. The drive shaft 51 is rotatably connected to the base frame 1 through a plurality of spaced shaft plates 52. Gears 53 are fixedly mounted on both sides of the drive shaft 51, and the gears 53 mesh with corresponding racks 4. A rotary drive component 55 is connected to the base frame 1 through a mounting plate 54. The rotary drive component 55 drives the drive shaft 51 to rotate through a transmission assembly 56.

[0029] Using this scheme, the drive shaft 51 is driven to rotate by the rotation drive component 55 and the transmission component 56. The drive shaft 51 drives the gears 53 on both sides to rotate synchronously. Through the meshing connection between the gears 53 and the racks 4, the effect of driving the two racks 4 to move synchronously in the same direction can be achieved.

[0030] In a further optimized design, the transmission assembly 56 includes a worm gear 561 that is poweredly connected to the output shaft of the rotary drive component 55. A worm wheel 562 is meshed on one side of the worm gear 561 and is fixedly mounted on the drive shaft 51.

[0031] In this embodiment, the worm gear 561 is arranged vertically, and a mounting base 563 is fixed on the base frame 1. The worm gear 561 is rotatably connected to the mounting base 563. By rotating the drive component 55, the worm gear 561 is driven to rotate, and the worm gear 561 drives the worm wheel 562 to rotate, thereby achieving the effect of driving the drive shaft 51 to rotate.

[0032] Further optimizing the scheme, the second drive mechanism 7 includes a gear ring 71 fixedly connected to one end of the drum screen 6. The two sides and the bottom of the gear ring 71 are respectively meshed with a drive gear 72, a driven gear 73, and multiple support gears 74. The drive gear 72 is fixedly mounted on the output shaft of the second rotary drive component 75, which is mounted on the mounting frame 2. The driven gear 73 and the support gears 74 are rotatably connected to the mounting frame 2.

The second rotary drive component 75 drives the drive gear 72 to rotate, and the drive gear 72 drives the gear ring 71 to rotate. With the cooperation of the driven gear 73, the support gear 74 and the rolling support part 76, the effect of driving the drum screen 6 to rotate can be achieved.

[0034] The design is further optimized so that the rolling support part 76 includes a limiting wheel 761 and a support wheel 762 respectively set on both sides and the bottom of the other end of the drum screen 6.
