DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: a high-speed raw material mixing device, comprising a mixing drum 1, a first spiral blade 8, a first mixing drum 2 and a second mixing drum 3 are symmetrically fixedly installed on the top of the mixing drum 1, a mixing motor 5 is fixedly installed at one end of the mixing drum 1, and stirring blades 6 are respectively installed inside the first mixing drum 2 and the second mixing drum 3, and a material guide blade 61 is installed in the middle of the connecting shaft of the mixing blade 6;

[0022] A second bevel gear 73 is fixedly installed at the bottom end of the connecting shaft of the stirring blade 6, and mounting plates 7 and first spiral blades 8 are symmetrically installed on both sides of the inner wall of the mixing barrel 1. The connecting shaft of the first spiral blade 8 on the left side is fixedly connected to the output end of the stirring motor 5. The middle of the two groups of mounting plates 7 are rotatably installed with second spiral blades 81, and the first bevel gears 72 are fixedly installed on the connecting shafts of the adjacent ends of the two groups of first spiral blades 8 and the second spiral blades 81;

[0023] The manual gates 4 provided at the connection between the first mixing drum 2 and the second mixing drum 3 and the mixing drum 1 are fan-shaped structures, and are closed on both sides outside the connecting shaft of the mixing blade 6, so that the communication port between the mixing drum and the mixing drum 1 can be closed. In this way, after the materials are mixed and stirred in the mixing drum, the manual gates 4 can be pushed outwards to guide the mixed materials into the inner cavity of the mixing drum 1. The manual gates 4 are common discharge gate structures, which will not be described in detail here.

[0024] A variety of materials can be classified according to their mixing characteristics and introduced into the first mixing drum 2 and the second mixing drum 3 respectively. The first mixing blade 8 is driven in the mixing drum 1 by the output end of the mixing motor 5. The end of the first mixing blade 8 transmits the second mixing blade 73 through the first bevel gear 72, so that the mixing blades and spiral blades inside the mixing drum 1, the first mixing drum 2 and the second mixing drum 3 can mix and stir the materials with different proportions in multiple dimensions, so that a variety of proportioned materials can be pre-mixed in the mixing drum according to the mixing characteristics of the materials, and the mixing effect between the materials is improved. In this way, when mixing a variety of materials, there is no need for multiple mixing devices to guide the materials to each other after mixing, which reduces the process and equipment costs. At the same time, the mixing and stirring mechanisms inside the mixing drum 1, the first mixing drum 2 and the second mixing drum 3 can be driven by a single motor, reducing the cost of structural parts.

[0025] Among them, a discharge pipe 11 is connected through the bottom of the mixing drum 1, and the first mixing drum 2 and the second mixing drum 3 are respectively connected to the mixing drum 1. Various materials can be classified according to mixing characteristics and introduced into the first mixing drum 2 and the second mixing drum 3 for pre-selected mixing. Then, after the manual gate 4 is opened, they can be introduced into the mixing drum 1 for mixing. In this way, when mixing multiple materials, there is no need for multiple mixing devices to mix and then guide the materials to each other, which reduces the process and equipment costs.

[0026] Among them, a mounting frame 21 is fixedly installed on the top of the inner cavity of the first mixing drum 2 and the second mixing drum 3, and a bracket 22 is fixedly installed on the outside of the first mixing drum 2 and the second mixing drum 3 respectively. The top end of the connecting shaft of the stirring blade 6 is rotatably installed in the middle of the corresponding mounting frame 21, and the bottom end of the connecting shaft of the stirring blade 6 is rotatably installed in the inner wall of the corresponding mounting plate 7.

[0027] Among them, a gate groove 41 is opened on one side of the connection between the first mixing drum 2 and the second mixing drum 3 and the mixing drum 1, and a manual gate 4 is symmetrically hinged on one side of the inner wall of the gate groove 41. A support rod 71 is fixedly installed between the two groups of mounting plates 7 and the inner wall of the mixing drum 1. The ends of the connecting shafts of the two groups of first spiral blades 8 are rotatably installed in the inner wall of the mounting plate 7 on the same side, and the first bevel gears 72 in the inner wall of each group of mounting plates 7 are respectively meshed with the outer edges of the second bevel gears 73. The first stirring blade 8 is driven in the mixing drum 1 by the output end of the stirring motor 5, and the end of the first stirring blade 8 transmits the second bevel gear 73 through the first bevel gear 72, so that the stirring blades and spiral blades inside the mixing drum 1, the first mixing drum 2 and the second mixing drum 3 can stir and mix the materials with different proportions in multiple dimensions, so that materials with multiple proportions can be mixed in the mixing drum according to the mixing characteristics of the materials, and the mixing effect between the materials is improved at the same time.

[0028] Working principle: When in use, multiple materials are first mixed and then proportioned separately. The materials can be classified according to their mixing characteristics (physical and chemical) and introduced into the first mixing drum 2 and the second mixing drum 3 respectively;

[0029] Then, the first stirring blade 8 is driven in the mixing drum 1 by the output end of the stirring motor 5, and the end of the first stirring blade 8 transmits the second bevel gear 73 through the first bevel gear 72, so that the stirring blades and spiral blades inside the mixing drum 1, the first mixing drum 2 and the second mixing drum 3 can stir and mix the materials with different proportions in multiple dimensions, so that materials with multiple proportions can be pre-mixed in the mixing drum according to the mixing characteristics of the materials, and the mixing effect between the materials is improved at the same time;

[0030] After the materials in the first mixing drum 2 and the second mixing drum 3 are mixed for a certain period of time, the manual gate 4 at the gate slot 41 can be pushed outwards, so that the pre-selected mixed materials can be introduced into the mixing drum 1. In this way, when mixing multiple raw materials in different proportions, it is not necessary to use multiple mixing devices to guide the materials to each other after mixing, which reduces the process of guiding the materials to each other. At the same time, the cost between the device structural parts is reduced through the separate motor drive parts.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
