Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1-3, one kind of the invention stirs evenly device, for being stirred evenly to cement mortar, including stir evenly bucket 1,
Gantry 3, outer cover 4 and main shaft 2 are fixedly installed on the main shaft 2 and multiple stir evenly piece 21,3 lower end of the gantry fixed setting
There are two with upper supporting leg 31, the supporting leg 31 can be converted into upwards by hinge, make the outer surface of supporting leg 3 and the outer surface of gantry 3
Fitting, to can save parking space when not using the present apparatus, the outer cover 4 is fixedly mounted on 3 upper end of gantry, and institute
State and be provided with accommodating chamber 40 in outer cover 4, it is described stir evenly 1 lower end of bucket and hold 32 by Shaft be mounted in the gantry 3, it is described
It stirs evenly 1 upper end of bucket to be mounted in 4 upper end wall of outer cover by upper swivel bearing 42,1 bottom end of bucket that stirs evenly is fixedly installed with
Baffle 11, the main shaft 2 be rotatably installed in the baffle 11 and it is described stir evenly between 1 roof of bucket, 2 upper end of main shaft is long
It is described out to stir evenly 1 roof of bucket and be fixedly installed with the first transfer wheel 22, electric rotating motivation 5, institute are fixedly installed in the outer cover 4
It states 5 upper and lower ends of electric rotating motivation and is connected separately with rotary shaft 52 and Shaft 51, upper 52 upper end of rotary shaft and institute
It states 51 lower end of Shaft to be respectively rotatably mounted in the upper end wall and lower end wall of the outer cover 4, the upper rotary shaft 52
The upper end wall of the outer cover 4 is grown upwards and is fixedly installed with the second transfer wheel 54, second transfer wheel 54 and described first
It is fitted with transmitting item 25 in transfer wheel 22, rotation toothed wheel 53 is fixedly installed on the Shaft 51, it is described to stir evenly
The rotary teeth head matched with the rotation toothed wheel 53 is fixedly installed on the outer end face that bucket 1 is located in the accommodating chamber
14。
Valuably, hole 110 is set in the baffle 11, and described hole 110 stirs evenly cement to allow to have stirred evenly
Mortar is fallen downwards, and described hole 110 is provided with inclined-plane 111, is trapped in the baffle 11 to reduce and stir evenly cement mortar
On.
Valuably, 1 upper end of bucket that stirs evenly is provided with implantation mouth 13, and 1 bottom of bucket that stirs evenly is provided with pointed bucket bottom 10,
Pointed 10 end of bucket bottom is provided with outflux 12.
Valuably, it is provided with gate valve, gate valve closing when stirring evenly operation on the outflux 12, and is completed stirring evenly
After open, so that cement mortar be allowed to flow out.
Since 1 bottom of bucket that stirs evenly is provided with pointed bucket bottom 10, gap can be formed between the baffle 11,
To which the cement mortar after stirring evenly can fall into the outflux 12 from described hole 110, due to the rotary teeth head 14 with
Rotation toothed wheel 53 matches, and therefore, in the rotation toothed wheel 53 rotation, the rotary teeth head 14 can be with the rotation
The opposite direction of toothed wheel 53 rotates, and rotates to stir evenly the direction opposite with the rotation toothed wheel 53 of bucket 1 described in driving, and
Due to being fitted with transmitting item 25 in second transfer wheel 54 and first transfer wheel 22, the main shaft 2 and institute
The direction of rotation for stating rotary teeth head 14 is identical, therefore the final main shaft 2 is opposite with the direction of rotation for stirring evenly bucket 1；When need
When carrying out stirring evenly operation to cement mortar, the gate valve is first closed, then cement mortar is poured into institute from the implantation mouth 13
It states and stirs evenly in bucket 1, run the electric rotating motivation 5, the electric rotating motivation 5 drives the upper rotary shaft 52 and the lower rotation
Axis 51 rotates, so that second transfer wheel 54 and the rotation toothed wheel 53 is driven to rotate, and the main shaft 2 can be stirred with described
Even 1 opposite direction of bucket, which is rotated and driven, to be stirred evenly piece 21 and stirs evenly to cement mortar, after the completion of stirring evenly, stops the electric rotating motivation 5, and
The gate valve is opened, the object that stirs evenly after stirring evenly is exported from the outflux 12.
The beneficial effects of the present invention are: it is provided with pointed bucket bottom due to stirring evenly a barrel bottom, it can be formed between baffle
Gap, so that the cement mortar after stirring evenly can fall into the outflux from described hole, and hole is provided with inclined-plane, thus
It can be reduced in cement mortar outflow and stir evenly cement mortar and be trapped on baffle；Due to electric rotating motivation operation when, main shaft with
The direction of rotation of bucket is stirred evenly on the contrary, therefore, main shaft can be substantially increased and stir evenly piece and stir evenly the relative rotational of bucket, thus
It is greatly improved when stirring evenly cement mortar and stirs evenly efficiency；Outer cover, which is mounted on, to be stirred evenly on barrel periphery, and electric rotating on the one hand can be facilitated
On the other hand the installation of motivation can prevent from contacting when stirring evenly bucket rotation with foreign object, play the role of protective separation；Apparatus of the present invention knot
Structure is simple, easy to use, and operation is firm, and equipment cost is low, and it is good to stir evenly effect.
The above, the specific embodiment only invented, but invent protection scope be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection scope of invention.Therefore, the protection scope of invention
It should be determined by the scope of protection defined in the claims.
