SUMMERY OF THE UTILITY MODEL
To the defect that current conveyer can only carry the material, the utility model aims to provide a can carry the multiple material of different particle diameters and can the screw conveyer of intensive mixing multiple material simultaneously.
The utility model aims at adopting the following technical scheme to realize. According to the utility model provides a screw conveyer with function of premixing, be equipped with helical blade's cylinder, supporting roller including gear motor, drive mechanism, inner wall, be equipped with the doctor-bar that the tip that the side is connected, keeps away from the cylinder axis and cylinder inner wall connection just inclines towards helical blade's spiral direction on the helical blade.
Furthermore, the transmission mechanism comprises a pinion fixedly arranged on a shaft of the speed reducing motor and a bull gear fixedly arranged on the outer wall of the roller along the circumferential direction and meshed with the pinion.
Furthermore, the scraping piece is provided with a groove extending along the reverse spiral direction of the spiral blade.
Furthermore, the other side surface of the scraping blade is provided with a baffle plate which extends along the direction parallel to the helical blade and is connected with the inner wall of the roller.
Further, the discharge hole of the roller is higher than the feed inlet.
The utility model relates to a screw conveyer with function of premixing is in transported substance material, and the doctor-bar can carry the granule material of different particle diameters to the cylinder top along with helical blade's motion, then shed downwards again, simultaneously because highly increasing progressively from the feed inlet to the discharge gate, the partial material that the doctor-bar carried can be shed backward to with the granule material intensive mixing of different particle diameters.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose, the following detailed description will be given to a specific embodiment, structure, features and effects of a screw conveyor with a premixing function according to the present invention with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 2, an embodiment of a screw conveyor with a premixing function according to the present invention is shown. The embodiment comprises a speed reducing motor, a transmission mechanism, a roller and a carrier roller. The transmission mechanism is a gear transmission mechanism, and specifically comprises: a motor shaft of the speed reducing motor can fix a pinion in a key connection mode and the like, and a large gear 2 meshed with the pinion is fixedly sleeved on the outer wall of the roller 1 along the circumferential direction. The roller 1 is supported on an idler which can limit the axial movement of the roller 1 so that the roller 1 can stably make circular motion around the axis. The inner wall of the roller is provided with helical blades 3, and the helical direction of the helical blades 3 is consistent with the rotating direction of the roller 1, so that the materials are pushed to move forwards. A plurality of scraping blades 4 are uniformly distributed on the helical blade 3 along the helical direction, in this embodiment, the scraping blades 4 are thin plates with uniform thickness and are respectively connected with the helical blade 3 and the roller 1, specifically: the end of the doctor blade 4 remote from the axis of the cylinder is connected to the inner wall of the cylinder (for example welded or screwed); one side surface of the scraping blade 4 is connected with the spiral blade 3 (for example, welded or screwed), the spiral direction of the spiral blade is defined as front and back, the end part of the scraping blade 4 close to the axis of the roller is positioned in front of the end part far away from the axis of the roller, so that the scraping blade 4 inclines towards the spiral direction of the spiral blade 3, when the roller 1 rotates, the scraping blade 4 moving to the bottom of the roller exerts an upward lifting force on the material at the bottom of the roller on one hand, and can carry part of the material to rotate to the top of the roller and then throw the material, thereby uniformly mixing the particle materials with different particle sizes. In addition, the roller at the two ends of the feed port and the discharge port of the roller 1 can be adjusted to enable the discharge port to be higher than the feed port, so that a part of materials carried by the scraping sheet 4 can be thrown backwards when the roller 1 rotates, and the materials with different particle sizes can be mixed more uniformly.
In another embodiment of the present invention, as shown in fig. 3 to 4, the scraping blade 4 is provided with a groove 401 extending along the reverse spiral direction of the spiral blade 3, so as to carry more materials to the top of the roller for being thrown downwards, and the other structures are the same as the previous embodiment.
In a further embodiment of the present invention, the other side of the scraping blade 4 is provided with a baffle extending in a direction parallel to the helical blade and connected to the inner wall of the drum to carry more materials to be thrown when the drum rotates, so as to achieve a better mixing effect.
In this embodiment working process, the thickness material of different particle diameters passes through modes such as conveyer belt and gets into in the cylinder 1 from the feed inlet of cylinder 1, start gear motor, thereby the pinion rotation drives gear wheel 2 and makes cylinder 1 rotatory, 1 direction of rotation of cylinder is the same with helical blade 3's spiral direction, the thickness material of different particle diameters is along with helical blade 3's rotation, carry to the discharge gate, it is thrown downwards when moving simultaneously to the doctor-bar 4 of cylinder bottom and driving partial material arrival top, constantly circulate, when the material reaches the discharge gate, the material of different particle diameters has intensive mixing, can get into next stirring process.
The above description is only a preferred embodiment of the present invention, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
