[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 6 , the present invention provides a technical solution: Embodiment

[0028] A material mixing device for a radiation protection project includes a mixing box body 1 and a discharge pipeline 2 arranged on the left side of the mixing box body 1. A buffer mechanism is arranged at the bottom of the mixing box body 1, and a discharge mechanism is arranged inside the discharge pipeline 2.

[0029] The buffer mechanism includes a tripod 4, a damping block 401, a guide rod 402, a counterbore 403, a fixing member 404, a bottom plate 405, a connecting member 406, an upper pressing plate 407, a telescopic rod 408, a buffer spring 409, and a lower pressing plate 410. The tripod 4 is fixedly connected to the bottom of the mixing box body 1. The damping block 401 is fixedly connected to the bottom of the tripod 4. The guide rod 402 is fixedly connected to the bottom of the damping block 401. The connecting member 406 is fixedly connected to the bottom of the damping block 401. The upper pressing plate 407 is fixedly connected to the bottom of the connecting member 406. The telescopic rod 408 is fixedly connected to the bottom of the upper pressing plate 407.

[0030] When the mixing box body 1 is working, the relatively large vibration forces generated by the first motor 304 and the second motor 310 directly act on the damping block 401 fixedly connected to the bottom of the tripod 4. Subsequently, the damping block 401 acts on the connecting member 406 to drive the upper pressing plate 407 to vibrate. At this time, the vibration force will compress the buffer spring 409. When the buffer spring 409 reaches the maximum contraction amount, a restoring force will be generated, thereby offsetting the potential energy generated by the vibration, achieving the buffer effect, increasing the service life of the tripod 4, and ensuring the stability of the mixing box body 1.

[0032] On the basis of the first embodiment, a cover plate 5 is movably connected to the top of the mixing box body 1. A cover plate handle 6 is fixedly connected to the top of the cover plate 5. A stirring mechanism is arranged inside the mixing box body 1. The stirring mechanism includes a fixed frame 3, a first rotating shaft 301, a first stirring plate 302, a motor mounting seat 303, a first motor 304, a second rotating shaft 305, a second stirring plate 306, an external thread joint 307, an internal thread joint 308, a sealing ring 309 and a second motor 310. The fixed frame 3 is fixedly connected to the bottom of the mixing box body 1. The second motor 310 is fixedly connected to the top of the fixed frame 3. The external thread joint 307 is fixedly connected to the bottom of the mixing box body 1. The internal thread joint 308 is threadedly connected to the outer surface of the external thread joint 307. A through hole is formed at the bottom of the internal thread joint 308. The first rotating shaft 301 is rotatably connected to the inner wall of the through hole. The replaceable sealing ring 309 is arranged inside the internal thread joint 308. The sealing ring 309 is arranged at the bottom inner wall of the internal thread joint 308. The sealing ring 309 arranged at the bottom inner wall of the internal thread joint 308 can effectively prevent dripping when the first rotating shaft 301 rotates. The first rotating shaft 301 is rotatably connected to the inner wall of the external thread joint 307. The first stirring plate 302 is fixedly connected to the outer surface of the first rotating shaft 301. The motor mounting seat 303 is fixedly connected to the right side of the mixing box body 1. The first motor 304 is fixedly connected to the top of the motor mounting seat 303. The second rotating shaft 305 is arranged on the left side of the first motor 304. The output end of the second motor 310 is fixedly connected to the bottom of the first rotating shaft 301. The output end of the first motor 304 is fixedly connected to the right side of the second rotating shaft 305. Three first stirring plates 302 are evenly distributed on the outer surface of the first rotating shaft 301. Nine second stirring plates 306 are evenly distributed on the outer surface of the second stirring plate 306. The second stirring plate 306 is fixedly connected to the outer surface of the second rotating shaft 305.

[0033] Working principle:

[0034] First of all, through the stirring mechanism arranged inside the mixing box body 1, after pulling open the cover plate 5 and then turning on the first motor 304 and the second motor 310, the first rotating shaft 301 at the bottom inner wall of the mixing box body 1 and the second rotating shaft 305 at the side inner wall drive the first stirring plate 302 and the second stirring plate 306 to stir and mix the raw materials inside the mixing box body 1.

[0035] Furthermore, through the external thread joint 307 fixedly connected to the bottom of the mixing box body 1, and the external thread joint 307 is threadedly connected to the internal thread joint 308, and the sealing ring 309 is arranged at the bottom inner wall of the internal thread joint 308, which can effectively prevent dripping when the first rotating shaft 301 rotates.

[0036] Further, through the discharge mechanism provided on the left side of the mixing box body, rotating the rotating handle 201 controls the rotation of the threaded rod 203, driving the sealing cover 204 to move horizontally, which can control the discharge speed to a certain extent, and can be controlled by the threaded rod 203 when the sealing cover 204 is tightened, ensuring the sealing effect at the connection between the mixing box body 1 and the discharge pipe 2.

[0037] Furthermore, through the buffer mechanism provided at the bottom of the footrest 4, when the mixing box body 1 is working, the large vibration forces generated by the first motor 304 and the second motor 310 directly act on the damping block 401 fixedly connected to the bottom of the footrest 4. Subsequently, the damping block 401 acts on the connecting member 406 to drive the upper pressure plate 407 to vibrate. At this time, the vibration force compresses the buffer spring 409. When the buffer spring 409 reaches the maximum contraction amount, a restoring force will be generated, thereby offsetting the potential energy generated by the vibration, achieving the buffer effect, increasing the service life of the footrest 4, and ensuring the stability of the mixing box body 1.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
