One sides sliding of the cylinder 8 far from dispatch tube 2 is provided with anti-blocked shot 81, anti-blocked shot 81 close to one end of transmission shaft 31 be fixedly connected with
Concrete is stopped to enter the anti-blocking disk 82 of Anti-blocking cylindrical 8, anti-blocked shot 81 is fixedly connected with anti-far from one end of anti-blocking disk 82
Only anti-blocking disk 82 falls into the limited block 83 in spiral fan 33.When part more sticky in concrete is difficult in dispatch tube 2
When advancing, is temporarily stored in the anti-blocking disk 82 of the portion extrusion and entrance Anti-blocking cylindrical 8, make the faster concrete of conveying speed
Continue to transport, avoids the concrete for being difficult to transport blocking dispatch tube 2 and influence the transport of concrete.It is arranged on anti-blocked shot 81 anti-
Stifled spring 84, the both ends of anti-clogging spring 84 are fixed with one end of anti-blocking disk 82 and the separate dispatch tube 2 of Anti-blocking cylindrical 8 respectively to be connected
It connects, it is difficult to which the concrete of transport pushes anti-blocking disk 82 to tighten 84 stress of anti-clogging spring, when the faster concrete of travelling speed
After ringing off with the transport of spiral fan 33, anti-clogging spring 84 stretches naturally squeezes anti-blocking disk 82, it may be difficult to which the concrete of transport pushes away
Enter dispatch tube 2 and be transported in discharge port 6 by spiral fan 33 to be discharged, effectively concrete is avoided to block in screw conveyor
It happens.
The inner wall of Anti-blocking cylindrical 8 is fixedly connected with for detecting anti-blocking disk 82 relative to 8 bottom surface distance of Anti-blocking cylindrical
Sensor 7, when sensor 7 detects that anti-blocking disk 82 is slided along the direction far from transmission shaft 31, sensor 7 is to motor 3
Acceleration signals is issued, motor 3 is accelerated to rotate by acceleration signals, makes transmission shaft 31 that spiral fan 33 be driven to accelerate conveying coagulation
Soil avoids concrete from accumulating and influence the transport of concrete in dispatch tube 2.To avoid that may be present in concrete not grinding
Stone blocks the case where spiral fan 33 makes 3 torque of motor increased dramatically and damage motor 3, connects electricity using shaft coupling 32
Motivation 3 and transmission shaft 31, shaft coupling 32 can damage first when torque is excessive, to protect motor 3 and transmission shaft 31, together
When, shaft coupling 32 is also easy to dismantle, convenient for the installation or demolition and maintenance of motor 3.
To avoid concrete from entering the working region of motor 3 during transportation, in shaft coupling 32 far from motor 3
Side fixed setting separate ring flat-plate 21, separate ring flat-plate 21 outer peripheral edge be fixedly connected with the inner wall of dispatch tube 2, and separation ring flat-plate
21 are fixedly installed sealing ring 22 with the joint of transmission shaft 31, and sealing ring 22 increases the leakproofness for separating ring flat-plate 21, avoids mixing
Solidifying soil, which enters motor 3, damages motor 3.
It is fixedly connected with the loading hopper 51 that opening is greater than feed inlet 5 in the opening of feed inlet 5, will be mixed convenient for staff
Solidifying soil pours into dispatch tube 2 and will not spill, and is fixedly connected with stirring motor, stirring motor away from the outside of feed inlet 5 in dispatch tube 2
Driving rotor one end is fixedly connected with stirring flabellum 41, and stirring flabellum 41 is driven by stirring motor 4 to be rotated in dispatch tube 2, stirs
The concrete fallen by feed inlet 5 is mixed, the condensation of concrete is delayed, concrete is avoided to condense retrogradation in dispatch tube 2 and be difficult to
The case where conveying.
It is fixedly connected with the cyclic annular anchor ear 11 for fixing dispatch tube 2 in rack 1, cyclic annular anchor ear 11 is set in dispatch tube
2 both ends, and tightened cyclic annular anchor ear 11 using bolt, dispatch tube 2 is fixed in rack 1, convenient for the peace installation and dismantling of dispatch tube 2
It unloads.For the mechanical strength for reinforcing rack 1, rack 1 is avoided to damage because working for a long time, is fixedly connected and adds between rack 1
Strengthening tendons 12 prevent rack 1 from falling apart and jeopardize worker's life security.
Embodiment two
A kind of screw conveyor, the difference with embodiment one are that as shown in Figure 4,5,2 surface of dispatch tube offers material controlling
Slot 9,9 trough rim two sides of material controlling slot are fixedly connected there are two positioning plate 91, are plugged with crop control plate 92, crop control plate 92 between positioning plate 91
It slides and is protruded between spiral fan 33 along material controlling slot 9, conveying speed of the adjustable concrete in dispatch tube 2 works as material controlling
When plate 92 is inserted between spiral fan 33, concrete conveyance speed is slowed, and the Anti-blocking cylindrical 8 in embodiment one can be temporary at this time
When store concrete, avoid concrete from being blocked in dispatch tube 2, can either according to production need to adjust concrete conveying speed
Degree, and it is avoided that the stopping state that may occur in deceleration delivering concrete.
It is threaded with the caging bolt 93 for being same as fixed crop control plate 92 on positioning plate 91, tightens caging bolt 93, material controlling
Plate 92 is fixed between positioning plate 91, and not falling out in spiral fan 33 makes spiral fan 33 block and damage.
The working principle of the utility model is: concrete enters dispatch tube from the loading hopper 51 for be fixed on feed inlet 5
2,41 ready-mixed concrete of flabellum is stirred, slows down the rate of set of concrete, is fixed on the helical blade on transmission shaft 31 electronic
It might have the more sticky more difficult conveying in part in part under the driving of machine 3 along transfer drum transport concrete, concrete, this
It is difficult to transport the concrete sent a bit and can squeeze anti-blocking disk 82 and enter Anti-blocking cylindrical 8 and temporarily store, anti-blocking disk 82 squeezes at this time
And anti-clogging spring 84 is compressed, and the comparatively faster concrete of speed can be more than the concrete that enters in Anti-blocking cylindrical 8 from discharge port 6
Middle discharge effectively avoids the blocking of dispatch tube 2, and when faster concrete conveyance is completed, anti-clogging spring 84 will be in Anti-blocking cylindrical 8
Concrete squeeze into dispatch tube 2, by spiral fan 33 by the part concrete send out.Moreover, anti-blocking disk 82 is squeezed
And when sliding in Anti-blocking cylindrical 8 far from transmission shaft 31, i.e., there are stopping states in dispatch tube 2, and the detection of sensor 7 at this time is in place
It moves variation and conveys assisted instruction to motor 3, spiral fan 33 is made to accelerate rotation, concrete is accelerated to send out, avoids coagulation
Soil is accumulated in dispatch tube 2 and Anti-blocking cylindrical 8, and stirring flabellum 41 delays the condensation of concrete to the stirring of concrete, further
It is secondary to improve the anti-blocking ability of the utility model.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
