Abstract
The utility model provides a rotating shaft of a sand mixing cage, and the rotating shaft can be used for uniformly mixing sand, has a good mixing effect, and can be used for guaranteeing that sand is fully mixed, facilitating replacement of a sand mixing blade and saving the cost. The rotating shaft comprises a rotating shaft, wherein a transmission section and a sand mixing section are sequentially arranged on the rotating shaft in axial direction, the transmission section is provided with a screw blade, and the sand mixing section is provided with sand mixing blades. The rotating shaft is characterized in that the sand mixing blades are distributed in a plurality of rows in the axis direction of the rotating shaft, the adjacent rows of sand mixing blades are staggered, and adjacent sand mixing blades of the same row are arranged in opposite directions.
Description
Technical field
The utility model relates to precoated sand production equipment technical field, is specially the rotating shaft of mulling stirring cage.
Background technology
Precoated sand, sand grain surface is covered with molding sand or the core of one deck hard resin film before moulding, and it is roughing sand that precoated sand mainly adopts the selected natural siliceous sand of high-quality, and adds novolac resin, and curing agent, lubricant, reinforcing agent etc. are raw material.Precoated sand moulding is used in the intricate casting that dimension precision requirement is higher, one of optimum shaping materials such as automobile, tractor, hydraulic part, along with the development of domestic and international machinery industry especially automobile industry, more and more higher to casting quality requirement, the application that mould covers sand is more and more extensive.
Puddle mixer is a kind of visual plant during precoated sand is produced, by resin sand is added to resinoid bond and curing agent, mix fully, guarantee casting mold quality, produce satisfactory foundry goods, the mixed effect of more existing puddle mixers is undesirable, its design is unreasonable, mulling is inhomogeneous, part sand mixes and gets rid of from sand export without crossing fully, has affected the quality of finished sand, and part mulling blade is changed inconvenience after working long hours after serious wear simultaneously, can only whole rotating shaft, increased cost.
Utility model content
For the problems referred to above, the utility model provides the rotating shaft of mulling stirring cage, and its mulling is even, and good mixing effect is guaranteed that sand can fully mix, and is convenient to change mulling blade, cost-saving.
Its technical scheme is such: it comprises rotating shaft, described rotating shaft is provided with span line and mulling section vertically successively, described span line is provided with helical blade, described mulling section is provided with mulling blade, it is characterized in that: described mulling blade becomes some rows to distribute along the axis direction of described rotating shaft, described mulling blade between adjacent row is staggered, and with the upper adjacent described mulling blade of row, oppositely arranges.
It is further characterized in that: described rotating shaft is provided with articulation hole, and described mulling blade inserts in described articulation hole, and the end of described mulling blade passes through bolt-locking;
The cutter head place of described mulling blade is provided with wear plate.
Adopt after design of the present utility model, sand enters with rotating shaft and contacts from sand inlet, under the effect of the span line in continuous operation, push ahead, when sand arrives mulling section, under the effect of mulling blade, realize mixing and advance, the mulling blade oppositely arranging with row is thrown to rear by sand and is extended the time of staying of sand in mulling section, make sand can obtain full and uniform mixing, mulling effect improves, mulling blade is by articulation hole and being bolted on rotating shaft, be convenient to change mulling blade, without whole replacing rotating shaft, cost-saving, the cutter head place of mulling blade is provided with wear plate and has extended the service life of mulling blade.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
See Fig. 1, the utility model comprises rotating shaft 1, rotating shaft 1 is provided with span line 2 and mulling section 3 vertically successively, span line 2 is provided with helical blade 4, mulling section 3 is provided with mulling blade 5, mulling blade 5 becomes some rows to distribute along the axis direction of rotating shaft 1, mulling blade 5 between adjacent row is staggered, with the upper adjacent mulling blade 5 of row, oppositely arrange, rotating shaft 1 is provided with articulation hole 6, mulling blade 5 inserts in articulation hole 6, and the end of mulling blade 5 is locked by bolt 7, and the cutter head place of mulling blade 5 is provided with wear plate 8.
Sand enters with rotating shaft 1 and contacts from sand inlet, under the effect of the span line 2 in continuous operation, push ahead, when sand arrives mulling section 3, under the effect of mulling blade 5, realize mixing and advance, the mulling blade 5 oppositely arranging with row is thrown to rear by sand and is extended the time of staying of sand in mulling section 3, make sand can obtain full and uniform mixing, mulling effect improves, mulling blade 5 is fixed on rotating shaft 1 by articulation hole 6 and bolt 7, be convenient to change mulling blade 5, without whole replacing rotating shaft 1, cost-saving, the wear plate 8 that the cutter head place of mulling blade 5 is provided with has extended the service life of mulling blade.
