Detailed implementation mode
[0019] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.
[0020] As Figures 1 to 3 shown, a charging and mixing device includes a workbench 1, a mixing drum 2 and a mixing mechanism. The mixing drum 2 is arranged on the workbench 1. An installation frame 11 is arranged on the workbench 1, and a power device 3 is arranged at the top of the installation frame 11; the mixing mechanism is arranged inside the mixing drum 2.
[0021] The mixing mechanism includes an auger rod 311, a mixing shaft 321, a mixing rod 4 and a scraper 41; a positioning block 21 is arranged at the top of the mixing drum 2, and the output shaft of the power device 3 penetrates through the top of the installation frame 11 and is connected to the positioning block 21; the top end of the auger rod 311 is separately connected to the output end of the power device 3; by driving the positioning block 21 to rotate through the power device 3, the rotation of the mixing drum 2 is realized. At the same time, when the mixing drum 2 rotates, the auger rod 311 rotates synchronously. By rotating the auger rod 311, the raw materials at the bottom of the mixing drum 2 can be stirred upward first to improve the mixing effect.
[0022] A driving gear 31 is arranged on the output shaft of the power device 3, and driven gears 32 are arranged on both sides of the driving gear 31. The driven gears 32 are meshed with the driving gear 31; the driving gear 31 and the driven gears 32 are rotatably arranged on the inner side wall of the top of the installation frame 11. The top of the mixing shaft 321 is connected to the driven gear 32, and a plurality of mixing rods 4 are arranged on the mixing shaft 321, and the scraper 41 is arranged on the side wall of the mixing rod 4.
[0023] The driving gear 31 is rotated by the power device 3, thereby driving the driven gears 32 on both sides to rotate, causing the stirring shaft 321 to rotate. The stirring shaft 321 drives the stirring rods 4 and the scraping plates 41 to rotate synchronously, realizing the stirring and mixing of raw materials. At the same time, since the rotation direction of the stirring shaft 321 is opposite to that of the stirring cylinder 2, this reverse rotation helps to improve the uniform mixing effect of the raw materials, and the inner wall of the stirring cylinder 2 can be scraped by the scraping plate 41, reducing the adhesion of raw materials on the inner wall of the stirring cylinder 2, reducing waste. At the same time, in cooperation with the installation of the auger rod 311, the raw materials accumulated at the bottom can be stirred upward and then stirred again, improving the stirring quality of the raw materials and effectively reducing the accumulation of raw materials.
[0024] A limit disk 5 is arranged on the auger rod 311.
[0025] By arranging the limit disk 5 on the auger rod 311, the range of upward stirring of raw materials is controlled. At the same time, the raw materials stirred upward are dispersed into the stirring rods 4 on both sides during the rotation process by the limit disk 5 and continue to be stirred, improving the stirring efficiency.
[0026] A rotating ring 22 is arranged at the bottom of the stirring cylinder 2. The rotating ring 22 is rotatably arranged on the workbench 1, and a ball 221 is arranged between the rotating ring 22 and the workbench 1.
[0027] By arranging the rotating ring 22 and the ball 221, the friction between the stirring cylinder 2 and the workbench 1 during rotation is reduced, making the rotation of the stirring cylinder 2 easier and smoother, reducing energy consumption and improving stirring efficiency; at the same time, the wear between the rotating ring 22 and the workbench 1 is reduced, extending the service life of the equipment.
[0028] A number of bristles 411 are arranged on the scraping plate 41, and the bristles 411 are in contact with the inner wall of the stirring cylinder 2.
[0029] By arranging the bristles, they can directly contact the inner wall of the stirring cylinder 2. As the stirring cylinder 2 and the scraping plate 41 rotate in opposite directions, the bristles 411 can remove the raw materials attached to the inner wall of the stirring cylinder 2, thereby improving the cleaning effect of the stirring cylinder 2.
[0030] An auxiliary ring 6 is sleeved on the outer peripheral wall of the stirring cylinder 2, and one end of the auxiliary ring 6 is fixedly arranged on the side wall of the mounting frame 11.
[0031] By arranging the auxiliary ring 6, an additional support point is provided for the stirring cylinder 2, enhancing the stability of the stirring cylinder 2 during rotation.
[0032] Working principle of the utility model: The staff adds the raw materials of the emulsion explosive to be stirred into the stirring barrel 2, and starts the power device 3. The power device 3 is preferably a rotating motor. The output end of the power device 3 is connected to the positioning block 21 at the top of the stirring barrel 2 to drive the stirring barrel 2 to rotate. At the same time, the auger rod 311 inside the stirring barrel 2 is separately connected to the output end of the power device 3. During the rotation of the stirring barrel 2, the auger rod 311 also rotates. Through the rotation of the auger rod 311, the raw materials of the emulsion explosive accumulated at the bottom of the stirring barrel 2 are continuously stirred upward. At the same time, the driving gear 31 on the output shaft of the power device 3 drives the driven gears 32 on both sides to rotate, and then drives the stirring shaft 321 in the stirring barrel 2 to rotate. The stirring rods 4 and the scraping plates 41 on the stirring shaft 321 fully stir the raw materials of the emulsion explosive, and the rotation direction of the stirring rods 4 is opposite to the rotation direction of the stirring barrel 2. This reverse rotation helps to improve the uniform mixing effect of the raw materials and ensure the performance and quality of the emulsion explosive. At the same time, the scraping plates 41 can clean the inner wall of the stirring barrel 2 to prevent the raw materials of the emulsion explosive from accumulating on the inner wall and causing waste.
[0033] The above embodiments are only used to illustrate the technical method of the utility model and not to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the utility model.
