[0002] A scraper conveyor is a continuous conveying device that transports bulk materials within a closed rectangular cross-section using a moving scraper chain. Existing scraper conveyors consist of a head, intermediate section, and tail section, each with sprockets. Once material enters the scraper conveyor, the scraper chain engages with the head and tail sprockets, driving the entire scraper along the partitions to complete the conveying process.

[0019] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0020] See also Figures 1 to 3The utility model provides an anti-blocking mechanism for a self-cleaning scraper conveyor, comprising a head 1, a tail (not shown in the figure), a head sprocket 2, a tail sprocket and an anti-blocking mechanism, the anti-blocking mechanism comprising an auxiliary sprocket 4, a proximity sensor 6 and a controller, the head sprocket 2 and the auxiliary sprocket 4 are sequentially arranged at the head 1, the tail sprocket is arranged at the tail, the scraper chain (not shown in the figure) surrounds the head sprocket 2, the auxiliary sprocket 4 and the tail sprocket to form a ring, the head sprocket 2 is driven by a motor 3 to rotate, and the auxiliary sprocket 4 is rotatably arranged in the head 1 through an auxiliary shaft 5. It is worth noting that, with reference to Figure 4 A proximity sensor 6 is provided at one end of the auxiliary shaft 5 , and an output end of the proximity sensor 6 is electrically connected to a controller, which is also electrically connected to the motor 3 .

[0021] In this embodiment, the output shaft of the motor 3 is passed through the machine head 1, and the machine head sprocket 2 is fixed on the output shaft. When the controller controls the motor 3 to stop outputting, the machine head sprocket 2 stops rotating, causing the scraper chain to stop transmitting, and the entire device to stop operating.

[0022] In this embodiment, the outer peripheries of the head sprocket 2, the auxiliary sprocket 4 and the tail sprocket are provided with teeth matching the scraper chain, and the transmission cooperation with the chain is achieved through the teeth on the sprocket.

[0023] In this embodiment, the front and rear ends of the scraper chain are respectively provided with a front material outlet 7 and a rear material outlet, and the front material outlet 7 is provided at the machine head 1 .

[0024] Furthermore, a side plate 8 is provided at the end of the head 1, and the side plate 8 is arranged downwardly in an inclined direction toward the front material outlet 7. By providing the side plate 8 inclined downward, the material can be guided to flow obliquely downward toward the front material outlet 7, reducing the residue and accumulation of the material.

[0025] Furthermore, the side panels 8 are detachably connected to the handpiece 1, making it easy to remove the side panels 8 for cleaning or repairing the inside of the handpiece 1. The side panels 8 and the handpiece 1 are detachably connected by screws.

[0026] In this embodiment, several vibrators 9 are provided on the outer wall of the die head 1. By providing multiple vibrators 9 on the outer wall of the die head 1, material compacted on the inner wall of the die head 1 can be shaken loose and discharged from the scraper conveyor under the transport of the scraper chain, thus achieving self-cleaning of the scraper conveyor. This process eliminates the need to stop the scraper conveyor and manually clean it, thereby improving the operating efficiency of the scraper conveyor.

[0027] Working principle: During the conveying process, the head sprocket 2 drives the scraper chain to move, and the scraper chain drives the auxiliary sprocket 4 to rotate. If the scraper chain breaks, the auxiliary sprocket 4 stops rotating immediately. After the proximity sensor 6 on the auxiliary shaft 5 receives the reflected signal, it sends a scraper blockage information to the controller, causing the controller to urgently stop the motor 3, thereby effectively avoiding equipment damage and reducing losses.

[0028] In summary, the present invention incorporates an anti-blocking mechanism within the scraper conveyor's head. Once the scraper chain breaks, a proximity sensor on the auxiliary shaft receives a signal and feeds it back to the controller, causing the entire scraper conveyor to stop immediately and transmitting the alarm to the central control system, thereby minimizing losses and safety accidents. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and possesses high industrial application value.
