DETAILED DESCRIPTION

[0018] Now in conjunction with the accompanying drawings, the utility model is further explained.

[0019] like Figure 1-4 As shown, an adjustable device for preventing bulk materials from entering the warehouse and blocking materials includes a rectangular frame 1, a blocking mechanism 3, an adjusting mechanism 8 and a debris removing mechanism 15. A plurality of blocking mechanisms 3 are installed on the rectangular frame 1 at equal intervals. An adjusting mechanism 8 is arranged between the plurality of blocking mechanisms 3 and the rectangular frame 1. The gaps between the blocking mechanisms 3 are synchronously adjusted by the adjusting mechanism 8, so that debris of different sizes can be blocked. A debris removing mechanism 15 is arranged above the blocking mechanism 3, and the debris blocked by the blocking mechanism 3 is cleaned up by the debris removing mechanism 15.

[0020] Each group of blocking mechanisms 3 is divided into two groups of swing rods 5, and the two groups of swing rods 5 are arranged front and back oppositely, each group of swing rods 5 is two swing rods 5, and the two swing rods 5 are hinged to each other, and multiple gear rods 4 are arranged between the two groups of swing rods 5. The two ends of the multiple gear rods 4 are installed on the swing rods 5 on both sides by welding. Multiple gear rods 4 are installed between each group of swing rods 5, and one gear rod 4 is installed at the hinge of the two swing rods 5 (the gear rod 4 passes through the two swing rods 5, and the swing rod 5 rotates along the gear rod 4, so that the two swing rods 5 are hinged. The adjustable slideway 2 is fixed on the top surface of the front and rear sides of the rectangular frame 1 by welding, and a sliding seat 24 is hinged below the ends of each swing rod 5 on both sides. The sliding seat 24 is clamped on the adjustable slideway 2 for sliding (the sliding seat 24 is a convex groove, the adjustable slideway 2 is a convex block rotated 180°, and the sliding seat 24 is clamped on the adjustable slideway 2 for sliding). The sliding of the end of the swing rod 5 is used to adjust the angle of the swing rod 5, so as to adjust the distance between the two sets of adjacent blocking mechanisms 3, so as to block debris of different sizes;

[0021] Two linkage rods 6 are arranged below the blocking mechanism 3, and a plurality of pull rods 7 arranged at equal intervals are fixed on the top surface of each linkage rod 6 by welding. The top of the pull rod 7 is connected to the gear rod 4 in the middle of each group of swing rods by welding. When the linkage rod 6 descends, the pull rod 7 pulls the gear rod 4 downward, so that the two ends of the swing rod 5 move outward, and the spacing between the blocking mechanisms 3 becomes smaller. When the linkage rod 6 rises, the pull rod 7 pushes the gear rod 4 upward, so that the two ends of the swing rod 5 move inward, and the spacing between the blocking mechanisms 3 becomes larger. An adjusting mechanism 8 is arranged between the two ends of the linkage rod 6 and the rectangular frame 1, and the height of the linkage rod 6 is adjusted by the adjusting mechanism 8.

[0022] The adjusting mechanism 8 includes a guide rod 13, a screw rod 14 and an adjusting motor 11. The adjusting motor 11 is installed on the top surface of the rectangular frame 1 by means of implementation and fastening (the output shaft of the adjusting motor 11 is downward), and vertical guide holes 12 penetrating the rectangular frame 1 are opened on the left and right ends of the rectangular frame 1. Vertical guide rods 13 are fixed to the tops of the left and right ends of the linkage rod 6 by welding. The guide rod 13 extends into the vertical guide hole 12 for lifting and lowering. An internal threaded hole extending downward is opened at the center of the top of the guide rod 13. A screw rod 14 is inserted into the internal threaded hole and the screw rod 14 is connected to the output shaft of the adjusting motor 11 by welding. The screw rod 14 extends into the vertical guide hole 12. At the same time, the top of the adjusting motor 11 closes the top of the vertical guide hole 1. The rotation of the screw rod 14 is achieved by the rotation of the adjusting motor 11, so that the guide rod 13 is lifted and lowered, so that the spacing between the blocking mechanisms 3 is adjusted, and real-time adjustment is achieved by adjusting the motor.

[0023] The debris removal mechanism 15 includes a rotating rod 16 and a discharge mechanism 17, wherein the rotating rod 16 is installed on the rectangular frame on the front and rear sides of each adjustable slide 2 through a bearing and a bearing seat, and multiple groups of discharge mechanisms 17 extending into the blocking mechanism 3 are installed on each rotating rod 16, and each group of discharge mechanisms 17 includes two discharge rods 18 and an elastic telescopic rod 19. A sliding sleeve 20 is installed at the root of each discharge rod 18 by welding. The rotating rod 16 is a hexagonal prism, and the sliding sleeve 20 is sleeved on the rotating rod 16. The inner wall of the sliding sleeve 20 is in contact with the outer wall of the rotating rod 16, and the top of the two discharge rods 18 is in contact with each other. An elastic telescopic rod 19 is fixed by welding (the elastic telescopic rod is an inner rod and an outer rod nested inside and outside, and the elastic telescopic rod 19 is a spring for pushing the inner rod in the outer shell of the telescopic rod), a locking bolt 21 is installed on the sliding sleeve 20, and the locking bolt 21 passes through the sliding sleeve and abuts on the rotating rod 16. A discharge motor 22 is installed on the right end of the rotating rod 16 by welding, and the discharge motor 22 drives the rotation of the rotating rod. A box body 23 is fixed by welding at the lower side of the outer side of the rotating rod 16, and the top of the box body 23 is fixed to the rectangular frame 1 by welding; when working (with Figure 3For example), when there are a lot of debris between the blocking mechanism 3, the rotating rod 16 on the left side swings counterclockwise, and the rotating rod 16 on the right side swings clockwise and counterclockwise, so that the debris on the blocking mechanism 3 is lifted up by the unloading rod 18. When the end of the unloading rod 18 away from the rotating rod 16 is higher than the rotating rod 16, the debris slides downward into the box body 23 for storage due to the effect of gravity, and the rotating rod 16 rotates back to its original position in the opposite direction.
