[0025] The following is combined with Figure 1 , further illustrating a specific implementation of an automatic device for preventing a fall of the present invention. An automatic device for preventing a fall of the present invention is not limited to the description of the following embodiments.

[0026] This embodiment provides a specific structure of an automatic device for preventing falling, such as Figure 1-3 As shown, an automatic device for preventing a fall comprises:

[0027] The first conveyor 1 has a stopper 6 disposed on one side of its outer wall for blocking the movement of materials;

[0028] The second conveyor 2 has a shaft 21 at one end of its bottom side and an electric cylinder 3 installed at the other side. The piston rod of the electric cylinder 3 can drive the second conveyor 2 to perform a circular motion with the shaft 21 as the center. A fixed plate 5 is fixedly provided on the outer wall of the second conveyor 2; and

[0029] The connecting assembly includes a sliding block 7, a connecting rod 8 for transmitting the connecting block 6, a rotating wheel 10 installed on the outer wall of the No. 1 conveyor 1, and a reset spring 11. The fixed plate 5 and the sliding block 7 are connected by an elastic rope, and the elastic rope is wound around the surface of the rotating wheel 10. The sliding block 7 is slidably set in a preset slide groove 9 on the surface of the No. 1 conveyor 1, and the reset spring 11 is filled in the slide groove 9.

[0030] In this device, only a single electric cylinder 3 is used, and the material transfer, blocking and conveying processing can be completed by utilizing the transmission operation between structures. At the same time, the entire device has a simple structure and low use cost.

[0031] like Figure 1 and 2 As shown, the baffle 6 comprises a base 61 welded to the outer wall of the No. 1 conveying channel 1 , a baffle 62 , and a connecting plate 63 welded to one end of the baffle 62 . The baffle 62 is flip-assembled into the base 61 .

[0032] like Figure 2 As shown, in the same plane, the angle formed between the connecting plate 63 and the baffle 62 is 45-60°.

[0033] like Figure 1As shown, a brush body 4 is installed on the side of the surface of the No. 2 conveyor path 2 adjacent to the No. 1 conveyor path 1, and the distance between the upper surface of the No. 2 conveyor path 2 and the upper surface of the No. 1 conveyor path 1 is 2-5 cm.

[0034] The above-mentioned two conveying paths are designed to be distributed vertically, and the brush body 4 is used to cover the gap between the two conveying paths, thereby preventing the material from falling through the gap during the conveying process.

[0035] During specific use, the electric cylinder 3 is turned on to drive the entire No. 2 conveyor 2 to perform circular motion with the shaft as the center, and then the entire No. 2 conveyor 2 is tilted, the brush on the brush body 4 contacts the surface of the No. 1 conveyor 1, and then the material on the No. 2 conveyor 2 slides onto the No. 1 conveyor 1.

[0036] like Figure 1 As shown, one end of the fixing plate 5 is fixedly connected to the outer wall of the No. 2 conveying lane 2 by setting screws. In the working state, the fixing plate 5 is always distributed in the area that fits the outer wall of the No. 1 conveying lane 1.

[0037] like Figure 2 and 3 As shown, one end of the connecting rod 8 is movably connected to the portion of the sliding block 7 extending to the outside of the sliding groove 9, and the other end is movably connected to the surface of the connecting plate 63.

[0038] like Figure 3 As shown, one end of the elastic rope is connected to the through hole preset on the surface of the fixing plate 5 in a binding manner, and the other end is fixedly connected to the surface of the sliding block 7.

[0039] like Figure 3 As shown, one end of the return spring 11 is welded to the surface of the sliding block 7, and the other end is welded to the inner wall of the sliding groove 9;

[0040] When the material enters the surface of the No. 1 conveyor 1, one end of the fixed plate 5 deflects downward, and the sliding block 7 is driven to slide upward in the slide groove 9 through the elastic rope. During this process, the return spring 11 generates an elastic restoring force;

[0041] Then, the connecting rod 8 drives the connecting plate 63 to deflect upward, so that the baffle 62 rotates counterclockwise with its connecting end with the base 61 as the rotation center, thereby blocking the boring. The outer surface of the baffle 62 can be covered with a rubber sleeve to play a protective role.

[0042] The above-mentioned connection assembly is used, and combined with the baffle 6 and the fixed plate 5, when the second conveyor 2 is tilted, the baffle 62 in the baffle 6 can automatically block the material to prevent the material from falling during the material transportation process.

[0043] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
