Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a drum mixer. Background Art

[0002] The drum mixer is a commonly used mixing equipment that mainly uses a rotating drum to mix materials. Its working principle is to use the rotation of the drum to continuously turn the materials inside the drum, thereby achieving the purpose of uniform mixing.

[0003] Since some current drum mixers have a single mixing direction, using only a single drum or a single stirring frame for co-rotation, the mixing efficiency is poor, the mixing intensity is low, and it takes a long time to complete the mixing process, which is difficult to meet processing requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a drum mixer, which, on the basis of the drum being able to rotate on its own, is equipped with a double stirring frame for mixing and stirring. At the same time, the double stirring frames rotate in opposite directions, which can provide better shear force and mixing intensity, thereby improving the material mixing efficiency.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a drum mixer, comprising a bracket and a drum body mounted on the bracket, wherein the left and right sides of the drum body are connected to connected extension cylinders, two first bearing seats are mounted on the top of the bracket, the first bearing seats support corresponding extension cylinders, and the bottom of the drum body is connected to a discharge valve;

[0006] The front side of the drum body is provided with a feeding structure, which extends into the drum body through the front extension cylinder;

[0007] A reduction motor and a drive motor are installed at the front and rear of the bracket respectively. A gear ring is provided on the front side of the drum body. The output shaft of the reduction motor is provided with a first gear. The first gear is engaged with the gear ring to drive the drum body to rotate.

[0008] The output shaft of the driving motor is fixed with a first stirring frame, which extends into the drum body through an extension cylinder at the rear and has a plurality of first stirring blades fixed on the surface;

[0009] The surface of the first stirring frame is rotatably connected to a sleeve, the front end of the sleeve is connected and fixed to a second stirring frame, the second stirring frame is arranged around the outer circumference of the first stirring frame, and the second stirring frame is provided with a second stirring blade that is staggered with the first stirring blade;

[0010] A transmission structure is provided between the first stirring frame and the sleeve.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The second stirring frame and the first stirring frame in the utility model rotate in opposite directions to each other, so that the first stirring blade and the second stirring blade can fully stir the material. Through this multiple reverse rotation, the relative movement between the materials can be increased, which is more conducive to breaking up the agglomeration of the materials and making the materials more evenly mixed; it also avoids the materials from staying in the dead corners of the drum body, improves the processing capacity of the entire stirring system, and accelerates the mixing efficiency of the materials.

DETAILED DESCRIPTION

[0019] like Figure 1-5 As shown, a drum mixer includes a bracket 1 and a drum body 2 mounted on the bracket 1. The left and right sides of the drum body 2 are connected to the extension cylinders 3. Two first bearing blocks 4 are installed on the top of the bracket 1. The first bearing blocks 4 support the corresponding extension cylinders 3. The bottom of the drum body 2 is connected to a discharge valve 5.

[0020] The front side of the drum body 2 is provided with a feeding structure, which extends into the drum body 2 through the front extension tube 3;

[0021] A reduction motor 6 and a drive motor 9 are installed at the front and rear of the bracket 1 respectively. A gear ring 8 is provided on the front side of the drum body 2. The output shaft of the reduction motor 6 is provided with a first gear 7. The first gear 7 is engaged with the gear ring 8 to drive the drum body 2 to rotate.

[0022] The output shaft of the driving motor 9 is fixed with a first stirring frame 10, which extends into the drum body 2 through the rear extension tube 3 and has a plurality of first stirring blades 11 fixed on the surface;

[0023] The first stirring frame 10 is rotatably connected to a sleeve 12, and the front end of the sleeve 12 is connected and fixed to a second stirring frame 13. The second stirring frame 13 is arranged around the outer periphery of the first stirring frame 10, and the second stirring frame 13 is provided with a second stirring blade 14 that is staggered with the first stirring blade 11.

[0024] A transmission structure is provided between the first stirring frame 10 and the sleeve 12 .

[0025] The transmission structure here includes the surface transmission structure of the first stirring frame 10, which includes a second gear 15, a third gear 17 and a fourth gear 18. The second gear 15 is fixed to the surface of the first stirring frame 10, and the fourth gear 18 is fixed to the surface of the sleeve 12. The second gear 15 and the fourth gear 18 are connected by the fourth gear 18; the fourth gear 18 is rotatably mounted on the side plate 16 and the side plate 16 is fixed to the bracket 1.

[0026] The feeding structure is used to add materials into the drum body 2, and the discharge valve 5 is used to discharge materials. When the reduction motor 6 is started, it can drive the first gear 7 to rotate, so that the first gear 7 can drive the gear ring 8 to rotate together, thereby realizing the self-rotation of the drum body 2, so that the materials can obtain a preliminary mixing effect. At this time, the drive motor 9 is started, and the drive motor 9 can drive the first stirring frame 10 to rotate rapidly, and the transmission structure on the surface of the drive motor 9 will also be able to drive the sleeve 12 to rotate in the opposite direction, which makes the second stirring frame 13 rotate in the opposite direction to the first stirring frame 10, so that the first stirring blade 11 and the second stirring blade 14 can stir the materials. Through this multiple reverse rotation, the relative movement between the materials can be increased, which is more conducive to breaking the agglomeration of the materials and making the materials more evenly mixed. It also avoids the materials from staying in the dead corner area in the drum body 2, improving the processing capacity of the entire stirring system, and accelerating the mixing efficiency of the materials.

[0027] Among them, when the first stirring frame 10 rotates, the second gear 15 will drive the third gear 17 to rotate, and the third gear 17 can drive the fourth gear 18 to rotate, and the rotation direction of the fourth gear 18 will be opposite to that of the second gear 15, thereby achieving the effect of opposite rotation directions of the first stirring frame 10 and the second stirring frame 13.

[0028] The feeding structure includes a feeding motor 23 and a conveying pipe 22, both of which are fixed on the top of the bracket 1. The conveying pipe 22 extends into the drum body 2 through the extension tube 3 at the rear. The output shaft of the feeding motor 23 passes through the interior of the conveying pipe 22 and is fixed with a spiral conveying blade 24. A feeding port is provided on the top of the conveying pipe 22.

[0029] The material can be added to the conveying pipe 22 through the feeding port. When the feeding motor 23 is started, it can drive the spiral conveying blade 24 to rotate, so that the material can be pushed into the drum body 2 by the spiral conveying blade 24. During this period, the material can also be stirred by the spiral conveying blade 24 to obtain a pre-mixed effect.

[0030] A scraper 19 is fixed to the outer side of the second stirring frame 13 , and the scraper 19 is in contact with the inner wall of the drum body 2 .

[0031] When the sleeve 12 drives the sleeve 12 to rotate, the scraper 19 can scrape the inner wall of the drum body 2, so that the material adhering to the inner wall of the drum body 2 can be scraped off.

[0032] A plurality of bearing seats 25 are fixed on the top of the bracket 1 , and support rollers 26 are supported on the bearing seats 25 . The support rollers 26 are in rolling connection with the outer wall of the drum body 2 .

[0033] When the drum body 2 rotates, the surface of the support roller 26 can contact the surface of the drum body 2, and the support roller 26 can also rotate, thereby providing a supporting effect for the drum body 2, thereby reducing the weight borne by the first bearing seat 4.

[0034] The bracket 1 is respectively mounted with a second bearing seat 20 and a third bearing seat 21 ; the first stirring frame 10 is rotatably mounted on the second bearing seat 20 , and the sleeve 12 is rotatably mounted on the third bearing seat 21 .

[0035] The second bearing seat 20 can provide support for the first stirring frame 10, and the third bearing seat 21 can support the surface of the sleeve 12, so that the first stirring frame 10 and the sleeve 12 can be more stable when rotating.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
