Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveying equipment, in particular to a double-shaft mixer. Background Art
[0002] When conveying materials, conveying equipment often requires mixing when multiple materials are mixed together. This requires the materials to be mixed as evenly as possible. Conventional conveying machinery can only transport materials from their starting point to their destination in their original state. When transporting hard materials such as cardboard or paste-like slurries, the capacity of the conveyor is limited or the mixing operation cannot be performed simultaneously. Current mixing conveying devices generally use a mixing-before-conveying method, whereby the material is first mixed in a mixer and then conveyed to a conveyor for transport. This is inefficient. Furthermore, when using blades for mixing, the gaps between the blades easily leak material, resulting in incomplete pulverization. Furthermore, the angle of the mixing blades is fixed, making it impossible to adjust the blades for different materials. For example, published patent 2015204929731 discloses a dual-shaft mixing conveying device that uses dual shafts to drive the blades for mixing during transport. However, this also suffers from the problems of low mixing efficiency due to gaps between the blades, which can easily leak material, and the inability to adjust the blade angle. Therefore, addressing the low mixing efficiency and the inability to adjust the angle of the mixing blades in current mixing conveying devices is particularly important. Utility Model Content
[0003] The purpose of the utility model is to provide a double-shaft mixer, which adopts double-shaft conveying. On the double shafts, blades are welded at a 180° offset, and the blades are divided into left-hand and right-hand directions. The double-shaft mixer adopts double shafts and four blades in different directions. There will be no jamming when conveying materials. At the same time, the materials can be crushed. The blades in different directions can perform stirring operations when conveying, which has the effect of mixing the materials evenly. At the same time, an auxiliary stirring rod is added to supplement the stirring force for the blade interval position. At the same time, the angles of the left-hand and right-hand blades are adjusted by adjusting the screws.
[0004] The utility model provides a twin-shaft mixer, comprising a casing, wherein left-handed blades and right-handed blades are arranged in the casing, a solid spiral is arranged in the middle position of the casing, the left-handed blades and the right-handed blades are staggered 180 degrees and welded on the solid spiral, a reducer and a drive motor are arranged on one side of the solid spiral, the drive motor is connected to the solid spiral through the reducer to provide power to the solid spiral, a tail device is arranged on the other side of the solid spiral, the reducer and the drive motor are connected through a hydraulic coupler, an auxiliary stirring rod is arranged on the solid spiral, and the auxiliary stirring rod is located at the interval between the left-handed blades and the right-handed blades.

The blades are divided into two directions: left-handed and right-handed. This dual-axis mixer adopts dual-axis and four blades in different directions. When conveying materials, there will be no jamming phenomenon. At the same time, the materials can be crushed. The blades in different directions can be used for stirring during conveying, which has the effect of mixing the materials evenly. The spiral blades are designed with two-way left and right spirals. They can convey perishable, sticky, easy to agglomerate and large materials. The materials are easily broken during the conveying process, making the materials more evenly broken and the crushing effect better. At the same time, an auxiliary stirring rod is added to supplement the stirring force at the blade interval position.
