[0003] For the above process, the currently adopted stirrer usually consists of a hopper, a driver, and a stirring assembly. The driver is arranged below the bottom of the hopper, and the output end of the driver is connected to the stirring assembly. The stirring assembly includes a transmission shaft, stirring blades, and a bearing assembly. The bearing assembly is fixed to the hopper, the transmission shaft is matched with the bearing assembly, the transmission shaft passes through the hopper and is connected to the output end of the driver, and one end of the stirring blade is connected to the transmission shaft.

[0004] There are usually multiple stirring blades. One end of these stirring blades is fixed to the transmission shaft, the other end of the stirring blade is a free end, the lengths of the stirring blades are the same, and the stirring blades are in a paddle structure. For a stirrer with such a structure, due to the limitations of the structure and length of the stirring blades, not only the thrust generated on the materials is small, the force for flipping the materials in the paddle structure is small, but also only the materials within the length range of the stirring blades can be stirred. Therefore, during the working process, the uniformity of stirring the materials is poor, and long-time stirring work is required, which is obviously not conducive to energy conservation. Content of the Utility Model

[0005] The utility model provides an energy-saving material mixing device, which has the characteristics of uniform stirring and reduced energy consumption.

[0006] The technical solutions for solving the above technical problems are as follows:

Detailed implementation mode

[0020] The present utility model will be further described in detail below in conjunction with the drawings and the detailed implementation mode.

[0021] An energy-saving material mixing device includes a frame 1, a hopper 2, a first driver A, and a stirring assembly. The hopper 2 is arranged on the frame 1. The output end of the first driver A is connected to the stirring assembly. At least a part of the stirring assembly is arranged in the hopper 2. The stirring assembly includes a transmission shaft 3 and a stirring unit. One end of the stirring unit is fixed to the transmission shaft 3. The stirring unit includes a first stirring unit, a second stirring unit, and a third stirring unit. The lengths of the first stirring unit, the second stirring unit, and the third stirring unit extending in the radial direction of the transmission shaft 3 are inconsistent. The first stirring unit, the second stirring unit, and the third stirring unit are located at the same or different height positions.

[0022] The number of the first stirring units can be one or more. The number of the second stirring units can be one or more. The number of the third stirring units can be one or more. When the numbers of the first stirring unit, the second stirring unit, and the third stirring unit are all one, the first stirring unit, the second stirring unit, and the third stirring unit are arranged on the same circumference and at the same height position. When the numbers of the first stirring unit, the second stirring unit, and the third stirring unit are all multiple, they can be arranged in multiple layers in the above-mentioned manner on the same circumference.

[0023] The first driver A is composed of a motor and a reducer. The motor can be an electric motor or a hydraulic motor. In this embodiment, an electric motor is preferably used. The reducer is a reduction gearbox.

[0024] In the present utility model, the lengths of the first stirring unit, the second stirring unit, and the third stirring unit extending along the radial direction of the transmission shaft 3 are inconsistent, so that the first stirring unit, the second stirring unit, and the third stirring unit can stir the material at different positions. If the lengths of the first stirring unit, the second stirring unit, and the third stirring unit increase in sequence, then the material stirred by the first stirring unit within the first radial range is stirred a second time by the second stirring unit, and the material stirred by the second stirring unit is then stirred by the third stirring unit. This method can not only stir the material more evenly, but also, due to the different lengths of the three stirring units, the resistance suffered will be reduced, and since the power of the first driver can be reduced, the energy consumption of the first driver A can thus be lowered.

[0025] The first stirring unit includes a first arm 4 and a first blade 5. One end of the first arm 4 is fixed to the transmission shaft 3, and preferably, one end of the first arm 4 is fixed to the transmission shaft 3 by welding. The other end of the first arm 4 is fixed to the first blade 5, and preferably, the other end of the first arm 4 is fixed to the first blade 5 by welding. In this embodiment, the shape of the first blade 5 is preferably a cuboid, and the end face of the other end of the first arm 4 is an inclined plane. Therefore, after the other end of the first arm 4 is fixed to the first blade 5, a first included angle J1 is formed between the first arm 4 and the first blade 5. The first included angle J1 is 25 - 60°, and the first included angle J1 can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, etc. In this embodiment, the first included angle J1 is preferably 27°.

[0026] The second stirring unit includes a second arm 6 and a second blade 7. One end of the second arm 6 is fixed to the transmission shaft 3, and preferably, one end of the second arm 6 is fixed to the transmission shaft 3 by welding. The other end of the second arm 6 is fixed to the second blade 7, and preferably, the other end of the second arm 6 is fixed to the second blade 7 by welding. In this embodiment, the shape of the second blade 7 is preferably a cuboid, and the end face of the other end of the second arm 6 is an inclined plane. Therefore, after the other end of the second arm 6 is fixed to the second blade 7, a second included angle J2 is formed between the second arm 6 and the second blade 7. The second included angle J2 is 30 - 60°, and the second included angle J2 can be 35°, 40°, 45°, 50°, 55°, etc. In this embodiment, the second included angle J2 is preferably 35°.

[0027] The second stirring unit includes a third arm 8 and a third blade 9. One end of the third arm 8 is fixed to the transmission shaft 3, and preferably, welding is used to fix one end of the third arm 8 to the transmission shaft 3. The other end of the third arm 8 is fixed to the third blade 9, and preferably, welding is used to fix the other end of the third arm 8 to the third blade 9. In this embodiment, the shape of the third blade 9 is preferably a cuboid, and the end face of the other end of the third arm 8 is an inclined plane. Therefore, after the other end of the third arm 8 is fixed to the third blade 9, a third included angle J3 is formed between the third arm 8 and the third blade 9. The third included angle J3 is 30 - 60°, and the third included angle J3 can be 35°, 40°, 45°, 50°, 55°, etc. In this embodiment, the third included angle J3 is preferably 35°.

[0028] In this embodiment, the length of the first arm 4 extending in the radial direction of the transmission shaft 3 is shorter than the length of the second arm 6 extending in the radial direction of the transmission shaft 3, and the length of the second arm 6 extending in the radial direction of the transmission shaft 3 is shorter than the length of the third arm 8 extending in the radial direction of the transmission shaft 3.

[0029] The present utility model further includes a second driver B and a feeder. The second driver B is composed of a motor and a reducer. The motor can be an electric motor or a hydraulic motor. In this embodiment, an electric motor is preferably used, and the reducer is a reduction gearbox.

[0030] The feeder includes a housing 10, a first transmission shaft 11, and a plurality of pushing blades 12. One end of the housing 10 is provided with a feed inlet 10a, which is matched with the output port 2a provided on the hopper 2. The housing 10 is also provided with a discharge port 10b. The first transmission shaft 11 passes through the housing 10, and the first transmission shaft 11 is connected to the second driver B. The pushing blades 12 are in a spiral state, and a plurality of pushing blades 12 are arranged on the first transmission shaft 11 at intervals.

[0031] Compared with the continuous spiral pushing blades in the prior art, the adjacent two pushing blades 12 in this embodiment are disconnected. When the material reaches between the two pushing blades 12, the pushing space of the material is enlarged, the blockage of the material is reduced, and the material is more likely to obtain the pushing force of the pushing blades 12, so that the material is more easily broken by the pushing blades 12 during the pushing process.

[0032] Finally, it should be noted that the above embodiments are only relatively preferred embodiments of the present utility model, rather than limiting it, let alone limiting the protection scope of the present utility model; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the protection scope of the claims.
