DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 12 The present invention provides a technical solution: a raw material mixing device, comprising a mounting platform 1, a spline sleeve 5 penetrates the top of the mounting platform 1, and the spline sleeve 5 is rotatably connected to the penetration point, and an inclined mixing barrel is fixedly connected to the top of the spline sleeve 5. The inclined mixing barrel is inclined. When the inclined mixing barrel starts to rotate around its own axis, its effect is better than that of a vertical mixer. When it rotates, the powder and granular materials inside it can start to flip and move, and the height and slope of the materials are constantly changed.

[0034] The inclined mixing barrel includes a barrel bottom 2, which is a hemispherical structure with an arc-shaped concave interior, and the outer wall of the barrel bottom 2 is fixedly connected to a straight barrel portion 3, the lowest point of the bottom outer wall of the barrel bottom 2 is fixedly connected to the top of the spline sleeve 5, the top of the barrel bottom 2 is a circular ring-shaped inclined surface, and a stirring and mixing mechanism is also provided inside the barrel bottom 2. By providing a special structure at the bottom of the barrel bottom 2, the movement and mixing of materials can be enhanced, and when the barrel bottom 2 starts to rotate, the materials can be moved irregularly to prevent the materials from being layered and ringed due to centrifugal force, resulting in segregation and affecting the uniformity of mixing.

[0035] It also includes a power mechanism for driving the spline sleeve 5 to rotate.

[0036] The present invention provides two preferred embodiments, but there are other variant embodiments for description and illustration. Embodiment 1

[0037] like Fig.11 As shown, the stirring and mixing mechanism includes a stirring motor, which is fixedly connected to the top of the straight barrel portion 3. A stirring shaft 24 is provided at the top of the straight barrel portion 3 and penetrates into the interior of the straight barrel portion 3. The stirring shaft 24 is rotatably connected to the penetration portion. The top of the stirring shaft 24 is fixedly connected to the output end of the stirring motor. At least three groups of second stirring blades 23 are fixedly connected to the outer wall of the stirring shaft 24. The three groups of second stirring blades 23 are arranged in sequence from top to bottom, and the spacing between every two groups of second stirring blades 23 decreases in sequence from top to bottom, and the cross-sections of the three groups of second stirring blades 23 become wider in sequence from top to bottom.

[0038] After the materials are proportioned and fed, the stirring motor is started to drive the stirring shaft 24 to rotate, thereby causing the three groups of second stirring blades 23 to rotate and start stirring and mixing the materials. Since the materials closer to the top are subjected to less pressure between the materials, the second stirring blades 23 closer to the top are made narrower, so that the turning of the top is more complete and violent. The wider second stirring blades 23 stir the bottom so that the violently moving materials at the top can move downward, thereby completing the effect of mixing up and down. When combined with the rotating mixing of the inclined mixing barrel, the uniformity of the mixing can be greatly improved.

[0039] Furthermore, on the basis of Example 1, the outer wall of the stirring shaft 24 near the bottom is also fixedly connected to the flow separation plate 22, and the flow separation plate 22 is an arc-shaped plate structure, and the outer wall of the flow separation plate 22 is also provided with a plurality of irregular holes with irregular distribution. By setting the flow separation plate 22, the flow separation plate 22 can stir and mix the inside of the bottom 2 of the barrel, and in conjunction with the stirring of the upper part, it is beneficial to mixing, realizes all-round mixing, reduces dead angles, and improves efficiency. Moreover, by setting the holes, the material inside the bottom 2 of the barrel will be spatially disturbed, that is, the exchange between materials is accelerated while stirring. Embodiment 2

[0040] like Figure 4 and Figure 5 As shown, further, the stirring and mixing mechanism includes an installation top plate 4, which is fixed on the top of the straight barrel portion 3 through supporting legs, and the bottom of the installation top plate 4 is fixedly connected to a suspension rod 6. The top of the straight barrel portion 3 is provided with an active area to prevent the suspension rod 6 from interfering with the rotation of the straight barrel portion 3. The bottom of the suspension rod 6 that penetrates into the straight barrel portion 3 is fixedly connected to a bearing seat 7, and the bearing seat 7 is located directly above the spline sleeve 5. The outer wall of the bearing seat 7 is penetrated by a first transmission rod 10, and the first transmission rod 10 is rotatably connected to the penetration point, and the outer wall of the first transmission rod 10 located inside the bearing seat 7 is fixedly connected to a second transmission rod 11, and the ends of the second transmission rod 11 are both rotatably connected to a first rotating shaft 14, and the outer walls of the two first rotating shafts 14 are both rotatably connected to third stirring blades 25, and also includes a transmission mechanism for driving the first rotating shaft 14 to rotate.

[0041] Furthermore, the transmission mechanism includes a first gear 12, which is fixedly connected to the end of the first rotating shaft 14 away from the bearing seat 7. The annular inclined surface at the top of the barrel bottom 2 is arranged with teeth 13. All the teeth 13 form an end gear. The first gear 12 is meshed and connected with the end gear, and the first gear 12 is arc-shaped near the outer wall of the straight barrel part 3.

[0042] Due to the rotation of the inclined surface of the barrel bottom 2 and the meshing of the first gear 12 and the end gear, when the barrel bottom 2 rotates, the first gear 12 will be driven to rotate along the end gear, so that the first rotating shaft 14 can rotate, so that the third stirring blade 25 can rotate, so that the material inside the inclined mixing barrel can be turned over and moved, and the movement of the material in space can be accelerated, which is beneficial to the mixing. The turning direction of the third stirring blade 25 is relatively perpendicular to the rotation direction of the barrel bottom 2, which is more conducive to the mixing of the materials, disrupting the movement of the materials, making the mixing more irregular, preventing segregation, and ensuring the uniformity of the material mixing. At the same time, due to the inclined surface setting at the top of the barrel bottom 2, the second transmission rod 11 It will also swing while rotating, which can make the material quickly concave for mixing, especially for powdery and granular materials, which is equivalent to digging a concave area in the middle of the sand pile, so that the surrounding powdery and granular materials can quickly approach the concave area, thereby further enhancing the mixing effect. In addition, the number of the third stirring blades 25 can be changed according to the quality and total quality of the material, so that the concave area of ​​the material can always exist, so that the material will be turned over while flowing to the concave area after turning over, thereby realizing a cycle, and in combination with the rotation of the inclined mixing barrel, the uniformity of the mixing is further improved. By improving the uniformity, the stirring time can be reduced, and the work efficiency is greatly improved.

[0043] Furthermore, the movable area is filled with compressed sponge, and the suspension rod 6 passes through the compressed sponge and is fixedly connected to the penetration point. By setting the movable area, the inclined mixing barrel is prevented from interfering with the position of the suspension rod 6 while rotating. By setting the compressed sponge, the powdery and granular materials will not overflow.

[0044] Furthermore, a matching action is added on the basis of the second embodiment. Both ends of the first transmission rod 10 are fixedly connected with a baffle 9, and the baffle 9 is in a petal shape, and the cross section of the baffle 9 is fan-shaped, and the longitudinal section of the baffle 9 is a right-angled unequal-sided fan. When the first rotating shaft 14 is performing a seesaw reciprocating action, due to the fixed connection relationship between the first transmission rod 10 and the second transmission rod 11, and the rotational connection relationship between the first transmission rod 10 and the bearing seat 7, the first transmission rod 10 will reciprocate at a small angle, thereby driving the baffle 9 to move synchronously, thereby blocking the material driven by the rotation of the barrel bottom 2 to a certain extent, so that the material on both sides of the baffle 9 can be in different states, one side is piled up, and the other side is concave, thereby adding local mixing on the basis of the inclined mixing barrel. This action is equivalent to blocking the flow of water, blocking the flow of water by countercurrent, and then removing the blockage, so that the water flow is more intense and turbulent. This description is also applicable to powdery and granular materials.

[0045] Furthermore, on the basis of the second embodiment, a blanking hole is provided at the lowest point of the inner wall of the barrel bottom 2, and the blanking hole passes through the barrel bottom 2, the mounting platform 1 and the outer wall of the spline sleeve 5 in sequence. The inner wall of the spline sleeve 5 is slidably connected with a spline shaft 15 up and down, and the spline shaft 15 is fixed to the spline sleeve 5 by a retaining spring structure, and when the spline sleeve 5 rotates, the spline shaft 15 is synchronously driven to rotate.

[0046] When the materials are mixed, the spline shaft 15 is taken out downward so that the mixed materials can enter the inner wall of the spline sleeve 5 through the drop hole and then drop downward. Due to the special design of the barrel bottom 2, the barrel bottom 2 is also similar to a conical drop hopper, which can also speed up the drop.

[0047] Furthermore, the bottom of the bearing seat 7 is rotatably connected to the second rotating shaft 20, the outer wall of the second rotating shaft 20 is fixedly connected to the first stirring blade 19, the bottom of the second rotating shaft 20 is provided with four limit holes, the top of the spline shaft 15 is provided with four mounting grooves, the inner walls of the mounting grooves are slidably connected to the limit rods 16, and springs 21 are fixedly connected between the bottom of the four limit rods 16 and the inner bottom of the mounting grooves, and the four limit rods 16 can be inserted into the four limit holes respectively.

[0048] Before putting the material into the inclined mixing barrel, we slide the spline shaft 15 upwards so that the limit rod 16 can cooperate with the limit. When stirring begins, the spline sleeve 5 rotates and can drive the spline shaft 15 and the second rotating shaft 20 to rotate synchronously, thereby disturbing and stirring the dead corner area at the bottom of the barrel bottom 2. By cooperating with the above-mentioned stirring and mixing mechanism, all-round and multi-level stirring and mixing can be achieved.

[0049] Furthermore, the power mechanism includes a motor, the output end of the motor is fixedly connected to the third gear 18, the outer wall of the spline sleeve 5 is fixedly connected to the second gear 17, the second gear 17 is meshingly connected with the third gear 18, and when the motor outputs, it can drive the spline sleeve 5 to start rotating.

[0050] Through the coordination of the above structures, the present invention can realize all-round and multi-level stirring and mixing, greatly improving the material uniformity and stirring efficiency.

[0051] Working principle: When the raw material mixing device is used, powdery and granular materials in different proportions are added to the bottom of the barrel bottom 2 respectively, and the power mechanism is started to make the spline sleeve 5 start to rotate, so that the entire inclined mixing barrel starts to rotate, so that the powdery and granular materials inside the inclined mixing barrel can start to flip and move, constantly changing the height and slope of the materials, and at the same time cooperating with the stirring and mixing mechanism, so that the materials in the inclined mixing barrel can be fully mixed.

[0052] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
