Description
Technical Field
The utility model relates to a fertilizer preparation technical field specifically is a fertile preparation equipment of boron magnesium.
Background
In the process of preparing the boron-magnesium fertilizer, raw materials and auxiliary materials of the boron-magnesium fertilizer need to be stirred firstly, the stirring is performed for uniformly mixing various raw materials, a stirring paddle of the existing stirrer generally adopts a rotating shaft in the vertical direction, and the rotating shaft is provided with a stirring paddle; the material enters the stirring box from the upper part and is output from the lower part, and in the process, the material is stirred by the rotating stirring shaft. The biggest drawbacks of this structure are: during stirring, materials are stirred by the rotation of the blades only in the movement process from top to bottom, and the materials in the upper layer and the lower layer cannot be stirred, so that the stirring effect is poor.
Disclosure of Invention
In order to solve the technical problem, the utility model aims to provide a tumbling type stirring paddle, wherein a stirring shaft is arranged in a stirring box and is connected with the output end of a motor through a coupling; two layers of blades are arranged on the stirring shaft, namely an inner side blade close to the stirring shaft and an outer side blade far away from the stirring shaft; the inner side blade is spiral, and the root of the spiral blade is fixed on the surface of the stirring shaft; the inner side paddle is divided into two symmetrical parts along the axial direction of the stirring shaft, and the spiral directions of the two parts are opposite;
the outer side paddle is also in a spiral shape, and the spiral direction of the outer side paddle is opposite to the spiral direction of the inner side paddle; the outer paddle is divided into two symmetrical parts along the axial direction of the stirring shaft, and the spiral directions of the two parts are opposite;
the radial outer end part of the outer side blade is fixed with the connecting rib, the two ends of the connecting rib are fixed with the fixing ring, and the fixing ring is fixed on the stirring shaft through the ribs.
The stirring shaft is provided with a convex shoulder, the stirring shaft is inserted into the bearing inner ring, and the convex shoulder at one side of the bearing is provided with a sealing gasket; a bearing cover is arranged on the other side of the bearing; and a washer and a nut are arranged on the outer side of the bearing cover, and the nut is screwed on the thread at the end of the bearing shaft.
The splice bar is 3, evenly sets up along solid fixed ring's circumference.
The utility model has the advantages that: the stirring shaft is provided with two layers of stirring blades, namely an inner side blade close to the stirring shaft and an outer side blade far away from the stirring shaft; two-layer stirring paddle leaf's spiral opposite direction, the stirring paddle leaf of both sides is also spiral opposite direction moreover, and consequently, during the stirring, the stirring paddle leaf of both sides drives the material and moves towards opposite direction, and then upwards overturns after the intermediate position of paddle converges, has realized the interactive mixture on upper and lower layer, brings better mixed effect from this.

FIG. 2 is a schematic view of the position A-A of FIG. 1;
FIG. 3 is a schematic view showing the connection between the stirring shaft and the stirring tank.
Detailed Description
The utility model is described in detail with the attached drawings, as shown in the figure, a stirring shaft 2 is arranged in a stirring box 1, and the stirring shaft 2 is connected with the output end of a motor 5 through a coupling 4; two layers of blades are arranged on the stirring shaft, namely an inner side blade 7 close to the stirring shaft and an outer side blade 6 far away from the stirring shaft; the blades of the inner side propeller 7 are spiral, and the root parts of the propeller blades are fixed on the surface of the stirring shaft; the inner side paddle is divided into two symmetrical parts along the axial direction of the stirring shaft, and the spiral directions of the two parts are opposite;
the outer blade 6 is also in a spiral shape, but the outer blade is in a ribbon spiral shape, and the spiral direction of the outer blade is opposite to that of the inner blade; the outer paddle is divided into two symmetrical parts along the axial direction of the stirring shaft, and the spiral directions of the two parts are opposite;
the radial outer tip of outside paddle is fixed with splice bar 8, and splice bar 8's both ends are fixed with solid fixed ring 10, and solid fixed ring passes through the rib to be fixed on the (mixing) shaft, and not drawn in the rib embodiment, its structure is: one end of the rib is fixed on the stirring shaft, and the other end of the rib is fixed with the fixed ring.
The stirring shaft is provided with a convex shoulder 11, the stirring shaft 2 is fixedly inserted into an inner ring of a bearing 12, and a sealing washer 13 is arranged at the convex shoulder at one side (the right side in figure 1) of the bearing; a bearing cover 14 is arranged at the other side of the bearing; the outside of the bearing cap is provided with a washer 15 and a nut 16 which is screwed onto the thread at the bearing shaft end.
Preferably, the number of the connecting ribs is 3, and the connecting ribs are uniformly arranged along the circumference of the fixing ring 10. Too many connecting ribs are not beneficial to stirring, and too few connecting ribs are insufficient in strength.
