The change or adjustment of their relative relationships shall also be regarded as the scope of implementation of the present invention without substantial change in the technical content.

[0041] As Figures 1 to 3 shown, the embodiment of the present invention provides an air blowing self-cleaning and anti-blocking rotary valve and a material conveying device including the air blowing self-cleaning and anti-blocking rotary valve. Among them, the air blowing self-cleaning and anti-blocking rotary valve includes a basic valve seat structure 1, a reduction motor structure 2, a material transfer valve body structure 3, a shaft end valve cover structure 4, a shaft seal assembly structure 5 and an air blowing and material cleaning structure 6, which are used to complete the established material transfer and conveying process through the cooperation of the basic valve seat structure 1, the reduction motor structure 2 and the material transfer valve body structure 3. When the material enters the adjacent material plate space of the basic valve seat structure 1 and the material transfer valve body structure 3, the reduction motor structure 2 drives the material transfer valve body structure 3 to rotate, so as to convey the material to the downstream equipment. At the same time, the cooperation of the shaft end valve cover structure 4 and the shaft seal assembly structure 5 can effectively ensure the material transfer stability of the material transfer valve body structure 3. In addition, the air blowing and material cleaning structure 6 can be used to perform timed one-way air blowing effectively corresponding to the material transfer and unloading process, further significantly improving the functional stability of the material conveying and enhancing the functional practicality. The specific settings are as follows:

[0042] Please refer to Figures 1 to 3The basic valve seat structure 1 includes a valve shell 11 and a feed port 12 and a discharge port 13 respectively opened at different positions of the valve shell 11; the base part of the reduction motor structure 2 is fixedly assembled on the outer wall of the valve shell 11, and the rotary output shaft of the reduction motor structure 2 extends through the valve shell 11; the transfer valve body structure 3 has a shaft mounting seat and a plurality of material plates fixedly connected to the outer side of the shaft mounting seat at uniform intervals. Specifically, the transfer valve body structure 3 is fixedly assembled on the rotary output shaft of the reduction motor structure 2 through the shaft mounting seat, and the transfer valve body structure 3 is connected and arranged with the feed port 12 and the discharge port 13 respectively corresponding to different positions of the plurality of material plates; it is used to realize that when the material enters the adjacent material plate space of the transfer valve body structure 3 from the feed port 12, the rotational kinetic energy output by the reduction motor structure 2 drives the transfer valve body structure 3 to rotate, thereby conveying the material to the downstream equipment through the discharge port 13 to complete the transfer and conveying process.

[0043] As a preferred solution of this embodiment, please refer to Figure 3 The opening area of ​​the feed port 12 and the opening area of ​​the discharge port 13 are both larger than the inlet area of ​​the adjacent material plates, so as to achieve feeding and unloading in at least two groups of adjacent material plate spaces simultaneously, effectively ensuring the material transfer and transportation efficiency.

[0044] Further preferably, the length of the transfer route from the feed port 12 to the discharge port 13 is shorter than the length of the transfer route from the discharge port 13 to the feed port 12, so as to further improve the transfer and unloading efficiency.

[0045] Please continue to refer to Figures 2 to 3 The outer wall of the valve housing 11 corresponding to the transfer position of the rotating output shaft of the reduction motor structure 2 is fixedly provided with a shaft end valve cover structure 4, and the inner side of the shaft end valve cover structure 4 corresponding to the outer side of the rotating output shaft of the reduction motor structure 2 is also equipped with a shaft seal assembly structure 5. The shaft seal assembly structure 5 can adopt but is not limited to a packing seal, which is used to effectively ensure the stability of the material transfer function of the material transfer valve body structure 3 through the cooperation between the shaft end valve cover structure 4 and the shaft seal assembly structure 5.

[0046] The air-blowing material cleaning structure 6 includes an air inlet connecting body 61 and a one-way valve member 62. Among them, the air inlet connecting body 61 is fixedly arranged on the valve housing member 11, and the outlet end of the air inlet connecting body 61 is connected and communicated with the inner cavity of the valve housing member 11. The outlet end of the air inlet connecting body 61 is correspondingly arranged with the transfer route from the feed port 12 to the discharge port 13, so as to use the air inlet connecting body 61 to output a purging air flow to the transfer route from the feed port 12 to the discharge port 13, thereby significantly reducing the possibility of materials sticking and accumulating on the material transfer valve body structure 3, enabling the materials to be quickly transported, solving the problem that the material transfer valve body structure 3 is prone to blockage and jamming during the transportation of single crystal materials, and effectively improving the operation efficiency of the valve body.

[0047] The one-way valve member 62 is assembled on the air inlet connecting body 61 to avoid the internal air pressure and material backflow in the basic valve seat structure 1 to the air inlet connecting body 61, further improving the functional stability.

[0048] The material conveying device further includes a blowing pump and an electric control structure. Among them, the blowing end of the blowing pump is connected and communicated with the inlet end of the air inlet connecting body 61. The electric control structure includes a power module and a control module connected by an electric circuit. The control module can be, but is not limited to, a single-chip microcomputer control board of model AT80C51 or a microcontroller of model STM32. The control output end of the control module is connected to the input end of a relay through an electric circuit, and the output ends of the relay are respectively connected to the blowing pump and the reduction motor structure 2 through an electric circuit, so as to realize the coordinated control of the rotation speed of the reduction motor structure 2 and the output interval period of the blowing pump through the electric control structure. Specifically, the output air flow of the blowing pump can correspond to each group of material plates respectively, further ensuring the smooth transportation of materials and improving the functional practicality.
