[0024] 1. Chute, 2. Mounting plate, 3. Ear plate, 4. L-shaped locking tongue, 5. Base, 6. Tightening bolt, 7. Chute blockage detector body, 8. Rotating shaft. Specific embodiments:

[0025] To make the purpose, technical solutions and advantages of the implementation of the present utility model clearer, the present utility model will now be further described in detail with reference to the drawings and the following embodiments, so that the public can better master the implementation method of the present utility model. The specific implementation scheme of the present utility model is as follows:

[0026] Chute blockage protection device, including a chute 1 with a hole, an installation plate 2 is arranged at the hole of the chute 1 in a hinged structure manner, two ear plates 3 are arranged on the outer end face of the chute 1 in a fixed structure manner, and an L-shaped locking tongue 4 is arranged between the two ear plates 3 in a rotating structure manner to lock the side of the installation plate 2 away from the hinge point; the installation plate is connected to the chute through a hinged structure, and then the L-shaped locking tongue 4 is used to lock the installation plate, without bolt connection, and the connection quality is more stable and reliable; a base 5 is arranged on the side of the L-shaped locking tongue 4 away from the installation plate 2, the base 5 is connected to the chute 1 in a fixed structure manner, and a tightening bolt 6 is arranged on the base 5 in a threaded meshing manner. When the L-shaped locking tongue 4 locks the installation plate 2, the end of the tightening bolt 6 is in contact connection with the L-shaped locking tongue 4. Through the cooperation of the tightening bolt and the ear plate, the L-shaped locking tongue is fixed, which is convenient for opening the installation plate; a chute blockage detector body 7 is arranged on the outside of the installation plate 2 in a fixed structure manner.

[0027] Specifically, the installation plate 2 is provided with a hinge or a hinge in a fixed structure, and the installation plate 2 is hinged to the chute 1 through the hinge or the hinge.

[0028] It should be noted that rotating shafts 8 are arranged on both sides of the vertical section of the L-shaped locking tongue 4 in a fixed structure manner, and this vertical section is the section close to the chute; the L-shaped locking tongue 4 is connected to the ear plate 3 through the rotating shafts 8.

[0029] The combination of the chute blockage detector body 7 and the installation plate 2 in this embodiment is a chute blockage detector of model CCS-1011.

[0030] It should be elaborated that the tightening bolt 6 is an internal hexagonal bolt, which is convenient for adjustment.

[0031] The working principle and working process of the present utility model are as follows:

[0032] When the blockage is relatively serious, use a tool to rotate the internal hexagonal bolt 6. As the end of the internal hexagonal bolt 6 gradually moves away from the installation plate 2, the pressure on the L-shaped locking tongue gradually weakens. Under the resistance of the blocked material, the installation plate 2 gradually rotates outward around the hinge. At the same time, the L-shaped locking tongue 4 also rotates around the rotating shaft 8 until the installation plate 2 pushes open the L-shaped locking tongue 4, the installation plate 2 opens, exposing the hole, stop rotating the internal hexagonal bolt 6, complete the opening work, and then use tools such as a shovel to clean out the blocked material.
