DETAILED DESCRIPTION

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] See also Figures 1 to 3The embodiment of the present application provides a coal gangue sintered brick raw material stirring and mixing device, including a stirring barrel 1, a feeding port 2 is provided on the top of the stirring barrel 1, a discharging port 3 is provided at the bottom of the stirring barrel 1, a stirring shaft 4 is rotatably installed in the stirring barrel 1, and several groups of stirring rods 5 are installed on the stirring shaft 4. The same group of stirring rods 5 are slidably clamped with the same auxiliary stirring shaft 6, and several auxiliary stirring rods 7 are installed on the auxiliary stirring shaft 6. An annular groove 8 is provided on the top of the stirring barrel 1, and the top of the auxiliary stirring shaft 6 extends from the annular groove 8. The two sides of the annular groove 8 are connected by a U-shaped shell 9. An annular plate 10 is installed in the U-shaped shell 9, and an irregular slide groove 11 is provided on the annular plate 10. A clamping block 12 is rotatably installed on the auxiliary stirring shaft 6, and the clamping block 12 is slidably clamped in the irregular slide groove 11. An annular rack 13 is installed on the stirring barrel 1, and a gear 14 is installed on the auxiliary stirring shaft 6. The gear 14 is meshed with the annular rack 13.

[0020] In this embodiment, the gangue raw material enters the mixing barrel 1 from the feed port 2 on the mixing barrel 1 for mixing. After the mixing is completed, the material is discharged through the discharge port 3 at the bottom of the mixing barrel 1. When the gangue raw material is being mixed, it is stirred by a plurality of stirring rods 5 on the stirring shaft 4. When the stirring shaft 4 rotates, it can drive the auxiliary stirring shaft 6 to rotate together. When the auxiliary stirring shaft 6 rotates, the gear 14 on it engages with the annular rack 13 on the mixing barrel 1, so that the auxiliary stirring shaft 6 can also rotate when it revolves, so that the plurality of auxiliary stirring rods 7 on it can mix the materials. The clamping block 12 at the top of the auxiliary stirring shaft 6 slides and clamps in the irregular chute 11 on the annular plate 10. Therefore, when the auxiliary stirring shaft 6 revolves, the lifting and lowering movement of the clamping block 12 in the irregular chute 11 enables the auxiliary stirring shaft 6 to move up and down. Thereby, the stirring range of the auxiliary stirring rod 7 is increased, and the stirring and mixing efficiency is improved; the annular rack 13 and the gear 14 both have a certain thickness, so that the two are always engaged when the auxiliary stirring shaft 6 is raised and lowered; the auxiliary stirring shaft 6 is extended from the annular groove 8, and the annular rack 13 and the gear 14 are both arranged outside the mixing barrel 1, so that the dust generated when the material is stirred has less influence on the engagement; the setting of the U-shaped shell 9 connects the two sides of the annular groove 8, reducing the damage to the stirring shaft 4 caused by vibration during stirring; the part of the clamping block 12 located in the irregular slide groove 11 is preferably cylindrical, so as to reduce friction, and the clamping block 12 should be made of hard metal material.

[0021] In some embodiments, in order to facilitate driving the stirring shaft 4 to rotate, a mounting bracket 15 is installed on the stirring barrel 1, and a rotation drive device 16 is installed on the mounting bracket 15. The rotation drive device 16 can be a motor, and the output end of the rotation drive device 16 is connected to the stirring shaft 4 for transmission.

[0022] In some embodiments, in order to facilitate scraping off the material adhering to the inner wall of the mixing barrel 1 so as to ensure uniform mixing, a plurality of scrapers 17 are installed on the mixing shaft 4 , and the scrapers 17 abut against the inner wall of the mixing barrel 1 .

[0023] In some embodiments, in order to facilitate the feeding of the mixing barrel 1, a sliding seal is provided on the feed port 2 with a gate plate 18 connected thereto, and a linear actuator 19 is installed on the mixing barrel 1. The linear actuator 19 can be an electric cylinder. The output end of the linear actuator 19 is connected to the gate plate 18.

[0024] In some embodiments, in order to facilitate the discharge of the mixing barrel 1, a sliding seal is provided on the discharge port 3 with a gate plate 20 connected thereto, and a linear actuator 21 is installed on the mixing barrel 1. The linear actuator 21 can be an electric cylinder, and the output end of the linear actuator 21 is connected to the gate plate 20.

[0025] In some embodiments, in order to reduce the resistance when the clamping block 12 rotates, a plurality of universal beads 22 are rotatably mounted on the clamping block 12 , and the universal beads 22 abut against the outer wall of the annular plate 10 .

[0026] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
