Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a double-shaft mixer. Background Art

[0002] When the conveying equipment is in the process of conveying materials, it is necessary to stir when encountering some multiple materials mixed together for conveying, and the materials are required to be mixed as evenly as possible. General conveying machinery can only be transported from the starting point to the destination in its original state. When transporting some cardboard-like hard objects or paste-like slurries, the capacity is stuck or it is impossible to perform stirring operations while conveying. The current stirring and conveying device generally adopts the method of stirring first and then transporting, that is, stirring by a mixer first, and then sending the materials to the conveyor for transportation after stirring is completed. The efficiency is not high, and when blades are used for stirring, the gaps between the blades are easy to leak materials, resulting in incomplete crushing. At the same time, the angle of the stirring blades is also fixed, and the blades cannot be adjusted when stirring and conveying different materials. For example, the disclosed patent 2015204929731 discloses a double-axis stirring and conveying device, which drives the blades to rotate by double shafts and stirs during the material transportation process, but there is also a problem that the blade interval is easy to leak materials, resulting in low stirring efficiency and the blade angle cannot be adjusted. Therefore, it is particularly important to solve the problem of low stirring efficiency and inability to adjust the angle of the stirring blades in the current stirring and conveying device. Summary of the invention

[0003] The purpose of the present invention 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-handed and right-handed directions. The double-shaft mixer adopts double shafts and four blades in different directions. There will be no jamming when conveying materials, and the materials can be crushed at the same time. The blades in different directions can carry out stirring operations during 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, and the angles of the left-handed blades and the right-handed blades are adjusted by adjusting the screws.

[0004] The present invention provides a double-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 by 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 blade and the right-handed blade.

[0005] A further improvement is that a hydraulic coupler protection cover is arranged outside the hydraulic coupler, and the hydraulic coupler is spirally connected to the entity through a coupling and a head drive device.

[0006] A further improvement is that a frame is arranged below the reducer and the drive motor, and the reducer and the drive motor are supported by the frame.

[0007] A further improvement is that a cover plate is provided on the casing, and a support is provided between the casing and the cover plate.

[0008] A further improvement is that a coupling protection cover is arranged outside the coupling.

[0009] A further improvement is that a gear shield is arranged outside the head driving device.

[0010] A further improvement is that the solid spiral is composed of two screws which are arranged parallel to each other, and adjusting screws are arranged at the rear sides of the left-handed blade and the right-handed blade, and the angles of the left-handed blade and the right-handed blade are adjusted by adjusting the adjusting screws.

[0011] The front end of the solid spiral is a left-handed blade and a right-handed blade, and a conveying screw is arranged on the side close to the tail device. The left-handed blade and the right-handed blade are used to cut and stir the material, and the stirred and mixed material is conveyed to the discharge port at the tail through the conveying screw.

[0012] The invention has the following beneficial effects: it adopts double-axis conveying, and blades are welded on the double-axis at an offset of 180°. The blades are divided into two directions: left-handed and right-handed. The double-axis mixer adopts double-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 to convey perishable, sticky, easy to agglomerate and bulky materials. The materials are easy to break during the conveying process, so that the materials are broken more evenly and the crushing effect is better. At the same time, an auxiliary stirring rod is added to supplement the stirring force for the blade spacing position. At the same time, the angles of the left-handed blades and the right-handed blades are adjusted by adjusting the screws, which is convenient for use in different working environments.
