[0015] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0016] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention and are not drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer can be changed arbitrarily, and the layer layout type may also be more complicated.

[0017] In the following description, numerous details are set forth to provide a more thorough explanation of the embodiments of the present invention; however, it is apparent to one skilled in the art that the embodiments of the present invention may be practiced without these specific details.

[0018] See also Figure 1 and Figure 2, an automatic blocking device for a raw material batching warehouse, comprising an upper cleaning blocking knife 1 and a lower cleaning blocking knife 2 installed in contact with the inner wall of a material bin 3, the upper cleaning blocking knife 1 and the lower cleaning blocking knife 2 are arranged vertically opposite to each other, and the lower cleaning blocking knife 2 is arranged close to the discharge port 4 of the material bin 3, the material bin 3 is installed with a driving assembly, the upper cleaning blocking knife 1 and the lower cleaning blocking knife 2 are both connected to the driving assembly, the upper cleaning blocking knife 1 and the lower cleaning blocking knife 2 rotate around the inner wall of the material bin 3 around the central axis of the material bin 3, and a material discharge sensing assembly for sensing material discharge is provided below the discharge port 4 of the material bin 3.

[0019] See also Figure 1 and Figure 2 The driving assembly includes an upper gear ring 5 fixedly connected to the upper cleaning and plugging knife 1 and a lower gear ring 6 fixedly connected to the lower cleaning and plugging knife 2. The upper gear ring 5 and the lower gear ring 6 are respectively engaged with an upper driving gear 7 and a lower driving gear 8. The upper driving gear 7 is connected to an upper driving motor 9, and the lower driving gear 8 is connected to a lower driving motor 10.

[0020] See also Figure 1 and Figure 2 The unloading sensing component includes a belt scale 11 installed below the discharge port 4 of the material bin 3.

[0021] See also Figure 1 and Figure 2 The material discharge sensing component further includes a material level sensor 12 installed at the discharge port 4 of the material bin 3 , and the material level sensor 12 is arranged in the forward direction of the belt scale 11 .

[0022] In practical applications, see Figure 1 and Figure 2 , the material in the material bin 3 goes down to the belt scale 11, and the belt scale 11 continuously measures the material weight while monitoring the weight change of the material on the belt scale 11. When the belt scale 11 detects that the material weight is abnormally reduced, the lower drive motor 10 is started to drive the lower drive gear 8 to rotate, driving the lower gear ring 6 to rotate, and then driving the lower clearing knife 2 to rotate around the inner wall of the material bin 3 around the central axis of the material bin 3, automatically clearing the material blocked at the discharge port 4 of the material bin 3; if the belt scale 11 detects that there is no obvious change in the material weight, the upper drive motor 9 is started to drive the upper drive gear 7 to rotate, It drives the upper gear ring 5 to rotate, and then drives the upper cleaning knife 1 to rotate around the central axis of the material bin 3 around the inner wall of the material bin 3, peeling the material from the inner wall of the silo above the discharge port 4 to enhance the fluidity of the material. The upper drive motor 9 and the lower drive motor 10 are both large-speed ratio reduction motors; when the belt scale 11 detects that the material weight is abnormally reduced, the material height on the belt scale 11 can be further monitored by the material level sensor 12, so as to timely determine whether there is material from the discharge port 4 to the belt scale 11, further improving the determination efficiency. The material level sensor 12 is an infrared ranging sensor.

[0023] After the upper drive motor 9 or lower drive motor 10 is started, it begins forward rotation and continues forward for 150 seconds or until the forward limit device is triggered. After a delay of 6 seconds, it begins reverse rotation and continues reverse for 150 seconds or until the reverse limit device is triggered. It then continues forward again after a delay of 6 seconds. If a stop signal is input during forward or reverse rotation, the machine stops and the position information is stored in the PLC. When the machine restarts, it continues in the direction it last ran in, stops at the set position, and then reverses after a delay.

[0024] The lower driving motor 10 can be started at a fixed time in the automatic state to clean the sticky wall and achieve the effect of preventing material blockage.

[0025] After the material breaks, after the lower drive motor 10 is started, if the material break signal exceeds the set value, the upper drive motor 9 is started to clear the material.

[0026] The present invention realizes all-round automatic anti-blocking and clearing, enhances the fluidity of the materials in the entire material bin 3, solves the problem of blockage in the throat when the materials are discharged, and does not require personnel on duty, thereby reducing the labor intensity of the staff and eliminating the safety hazards of personnel poking and clearing the materials.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
