The raw material in the powder bin 100 is transferred into the mixing chamber 400 by the screw conveyor 500, and the raw material in the aggregate bin 200 is transferred into the mixing chamber 400 by the inclined aggregate transfer means 300. The mixing chamber 400 is fixed at a position far from the ground by a support frame 420, and a space below the mixing chamber 400 can be used for parking a concrete transporting vehicle.

Referring to fig. 2 and 3, a discharge hole 410 is formed in one side of the stirring chamber 400 close to the ground, a discharge pipe 411 is connected to the discharge hole 410, aggregate and powder are fully mixed by adding water in the stirring chamber 400 and then discharged through the discharge pipe 411, and the aggregate and the powder directly enter a transport vehicle and are transported to a construction site by the transport vehicle.

The phenomenon that the concrete splashes can appear in teeter chamber 400 at the ejection of compact in-process for some concrete falls to subaerial and causes the waste, for reducing this phenomenon, is provided with clout collecting vat 800 below discharging pipe 411, and clout collecting vat 800's opening is the U type in this application embodiment, can enclose trilateral of transport vechicle feed inlet, and the area of concrete is collected in the increase. Mounting hole 810 has been seted up to clout collecting vat 800's edge, and the mounting hole 810 in-connection has vertical pole 820, and in this application embodiment, in order to strengthen the supporting role to clout collecting vat 800, mounting hole 810 and vertical pole 820 all are provided with a plurality ofly.

The internal thread is arranged in the mounting hole 810, the vertical rod 820 is provided with an external thread, the mounting hole 810 is in threaded connection with the vertical rod 820, the driving device 830 is arranged at the lower end of the vertical rod 820, the driving device 830 comprises a first bevel gear 831 coaxially and fixedly connected to the vertical rod 820, a second bevel gear 832 meshed with the first bevel gear 831 and a rotating motor 834, one side, far away from the first bevel gear 831, of the second bevel gear 832 is fixedly connected with a rotating shaft 833, the rotating shaft 833 is in coaxial connection with an output shaft of the rotating motor 834, and the rotating motor 834 can drive the vertical rod 820 to rotate. In the embodiment of the present application, in order to save power resources, only the end of one vertical rod 820 is provided with a driving device 830.

Because clout collecting vat 800 is supported at the eminence by vertical pole 820, the transport vechicle is gone to the teeter chamber 400 below and is probably met clout collecting vat 800, takes place the phenomenon of damaging in order to reduce clout collecting vat 800 when colliding, clout collecting vat 800 can remove in the direction that the transport vechicle was gone. A sliding rail 900 parallel to the running direction of the transport vehicle is arranged below the vertical rod 820, and the height of the sliding rail 900 is gradually increased from one end close to the vehicle head to one end far away from the vehicle head. The vertical rod 820 is inserted into the slide rail 900, and a roller 910 is provided at an end of the vertical rod 820. When the transport vechicle runs into clout collecting vat 800, clout collecting vat 800 can slide to the direction of keeping away from the transport vechicle along slide rail 900, and when the car stopped, clout collecting vat 800 slided to the direction of being close to the transport vechicle under the action of gravity, enclosed the trilateral of transport vechicle feed inlet until, gyro wheel 910 can reduce the frictional force of slip in-process.

Since the transport vehicle needs to run to the lower part of the mixing chamber 400 in a backing manner, the phenomenon that the feed inlet of the transport vehicle is misaligned with the discharge pipe 411 of the mixing chamber 400 may occur, so that concrete falls outside the vehicle, and therefore the transport vehicle positioning device 700 is arranged on the ground below the mixing chamber 400. Referring to fig. 1 and 4, a mounting plate 600 is provided below the mixing chamber 400, and a pressure sensor 710 is provided inside the mounting plate 600.

The collector of the NPN transistor Q1 is connected in series with the alarm 721, and then connected to the power supply, and the emitter is grounded.

When the rear wheel of the transport vehicle runs to the pressure sensor 710, the pressure applied to the pressure sensor 710 is higher than the set threshold pressure, the comparison signal K3 output by the comparator N is at a high level, and the alarm 721 sends out an alarm signal K2 to remind a driver that the transport vehicle has reached a specified position.

Because concrete loading needs a certain time, in order to reduce the phenomenon that the alarm 721 works all the time to cause disturbance to residents, the collector electrode of the NPN triode Q1 is also connected with a time relay KT, a coil KT1 of the time relay KT is connected with the collector electrode of the NPN triode Q1, and a normally closed contact KT1-1 is connected in series with a branch where the alarm 721 is located. When the NPN triode Q1 is communicated, the coil KT1 is electrified, the time relay KT starts timing, the normally closed contact KT1-1 is disconnected after the preset time is reached, the branch where the alarm 721 is located is disconnected, and the alarm 721 stops working. When the transport vehicle is driven off the pressure sensor 710, the time relay KT is restored to the initial state.

The embodiment of the application discloses an energy-saving mixing station's implementation principle does: the raw materials in the aggregate bin 200 and the powder bin 100 are transported to the mixing chamber 400 to be fully mixed to form concrete, and the concrete needs to be transported to a construction site by a transport vehicle after being mixed.

The transport vechicle need back a car and go to the teeter chamber 400 below, and teeter chamber 400 below is provided with mounting panel 600, is provided with transport vechicle positioner 700 on the mounting panel 600. When the rear wheels of the transport vehicle run to the transport vehicle positioning device 700, the transport vehicle positioning device 700 sends out an alarm signal K2 to remind a driver that the driver has reached a specified position and needs to stop to wait for the mixing chamber 400 to discharge.

Stirring chamber 400 below still is provided with clout collecting vat 800, and the staff opens the height that rotates motor 834 and adjust clout collecting vat 800 according to the height of transport vechicle feed inlet for clout collecting vat 800 and feed inlet height, clout collecting vat 800 can surround the trilateral of feed inlet for receive the concrete that the ejection of compact in-process splashes. After the discharge of the mixing chamber 400 is completed, the transport vehicle drives away from the mixing station, and at the moment, the worker can start the rotating motor 834 again to enable the excess material collecting tank 800 to descend to the ground, so that the concrete in the excess material collecting tank 800 is treated.

Transport vechicle positioner 700 can improve the accuracy that discharging pipe 411 and transport vechicle feed inlet align, has reduced the phenomenon that the concrete fell outside the car, and clout collecting vat 800 can be collected the concrete outside the spill car for the concrete obtains make full use of, has reduced the waste, has played energy saving's effect.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
