In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1-3The utility model provides an embodiment: a mixed material discharge port anti-sticking device, comprising a belt conveyor, a feed port 1 arranged at the rear of the belt conveyor, the belt conveyor is a device for conveying materials, the feed port 1 is located at the rear of the belt conveyor, receives the falling materials, and the anti-sticking device installed in the feed port 1 prevents the materials from sticking or piling up in the contact area, thereby ensuring continuous and smooth material transmission. The left and right sides of the inner wall of the feed port 1 at the contact end with the materials are respectively fixedly connected with a lifting frame 2, a slide groove is provided on the lifting frame 2, and an anti-sticking plate 3 is slidably matched in the slide groove for supporting and adjusting the height and position of the anti-sticking plate 3, so as to adapt to the falling angles of different materials. To adjust the height position of the anti-sticking plate 3, corresponding to the position of the impact after the material falls, the top of the anti-sticking plate 3 is fixedly connected with a chain lifting device 7, and the top of the anti-sticking plate 3 that contacts the material is provided with an extension part, and the extension part is L-shaped, and the extension part wraps the back-blowing pipe 4 and enters the device to prevent the material and debris from entering the air blowing port, blocking the back-blowing pipe 4, and preventing the back-blowing pipe 4 from being impacted and tilted when falling, thereby preventing the sticking of the material from becoming worse. The lateral end of the extension part is vertically arranged with the anti-sticking plate 3, and a plurality of back-blowing pipes 4 are connected between the lateral end of the extension part and the anti-sticking plate 3, and the pipeline of the back-blowing pipe 4 is connected to the air compressor 5, and is driven by the electric motor 6.

[0022] The anti-sticking plate 3 is arranged at an inclined surface at the contact end with the material, so as to increase the contact area with the falling material, and at the same time, the inclined surface makes the material fall more effectively, and effectively prevents the material from piling up and sticking. The air outlet of the back-blowing pipe 4 is arranged in parallel with the inclined surface of the anti-sticking plate 3, so as to make the back-blowing air cover the entire surface of the anti-sticking plate 3. The back-blowing pipe 4 uses compressed air to clean the anti-sticking plate 3, which not only removes the material, but also removes the moisture on the surface, so as to maintain the efficient operation of the equipment. The surface of the contact end of the anti-sticking plate 3 with the material is composed of a ceramic lining. The impact of the material when falling is borne by the ceramic lining. The lining has the characteristics of high impact resistance and wear resistance, so as to effectively extend the service life of the equipment. The bottom end of the vertical end of the extension part is coaxially arranged with the bottom end of the back-blowing pipe 4. Such a design will not make the extension part block the falling material, and at the same time, the blowing wind direction of the back-blowing pipe 4 is good.

[0023] When in use, first adjust the height position of the anti-sticking plate 3 to correspond to the angle of the falling material, so that the surface contacts the falling material, and at the same time, the electric motor 6 is driven to drive the air compressor 5 to start working, compress the external air source, and transmit it to the backflush pipe 4. The backflush pipe 4 is arranged parallel to the surface of the anti-sticking plate 3, and the moisture on the surface of the material on the anti-sticking plate 3 is blown off, and the material is blown into the silo. At the same time, the surface of the anti-sticking plate 3 is designed to be oblique, so that the material can fall off faster.

[0024] Example 2: Please refer to Figure 1 , 4 , based on Example 1, it also has the following structure:

[0025] The chain lifting device 7 includes a gear 701, a chain 702, and a driving motor 8. The gears 701 are symmetrically connected to the left and right sides of the top of the feed port 1, and are connected by an axis. The gear 701 transmits a driving force so that the chain 702 can move vertically, thereby controlling the up and down movement of the anti-sticking plate 3. The input end of the gear 701 is connected to the output end of the driving motor 8. A chain 702 is mounted on the gear 701. The chain 702 is meshed with the gear 701. The chain 702 rotates through the gear 701, thereby driving the anti-sticking plate 3 to be lifted or lowered. The chain 702 is fixedly connected to the top of the anti-sticking plate 3, and the other end is connected to the telescopic rod. When the chain 702 rises and falls, it is connected to a fixed position by the telescopic rod to prevent the chain 702 from falling off. The telescopic rod is fixedly connected to the top of the feed port 1. When in use, the drive motor 8 is driven, and the output shaft of the drive motor 8 rotates to drive the input shaft of the gear 701 to rotate. The gears 701 on both sides are connected and rotated through the shafts, and the chain 702 meshed on the outside is rotated to drive the anti-sticking plate 3 to be lifted or lowered.

[0026] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
