Description

Technical Field

[0001] The utility model relates to a feeding device capable of adjusting the feeding sequence and a concrete mixing station comprising the same. Background Art

[0002] In traditional mixing plants, sand and gravel aggregates enter the silo from the stockpile, are weighed in the silo and enter the hopper through a flat belt conveyor and an inclined belt conveyor, and are then transported to the mixing main unit by the hopper. During this process, sand and gravel aggregates of different particle sizes are mixed together, and the feeding order of sand and gravel aggregates of different particle sizes cannot be adjusted separately.

[0003] In order to improve the strength of concrete or meet special requirements, different concrete production processes are required, such as the sand-wrapping method. Special processes have specific requirements for the order of adding aggregates of different particle sizes. This requires improving the existing mixing station process, adding aggregates of different particle sizes separately, and the aggregate bin of the mixing plant is on top. The aggregates are directly fed into the mixer after being measured. The aggregate and powder collection and transportation forms of the mixing plant are relatively diversified and can be adapted to local conditions. However, the cost of mixing is high. The cost of a mixing plant with the same production capacity is about twice that of a mixing plant.

[0004] Existing mixing plants cannot flexibly adjust the order in which aggregates of different particle sizes are added, and cannot achieve concrete production that meets certain specific process requirements. Summary of the invention

[0005] In view of the above problems, the purpose of the utility model is to provide a feeding device with adjustable feeding sequence and a concrete mixing station including the same.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a feeding device with adjustable feeding sequence, comprising a feeding valve, a first waiting hopper, a second waiting hopper and a controller; the feeding valve comprises a feeding port and two discharging ports, the feeding port is connected with a conveyor belt for conveying aggregates, the two discharging ports are respectively connected with the first waiting hopper and the second waiting hopper, and the feeding valve, under the control of the controller, respectively distributes different aggregates to the first waiting hopper and the second waiting hopper.

[0008] Wherein, the outlet of the first material hopper is provided with an electronic valve, and the electronic valve is connected to the controller and is opened and closed under the control of the controller.

[0009] Wherein, the outlet of the second material hopper is provided with an electronic valve, and the electronic valve is connected to the controller and is opened and closed under the control of the controller.

[0010] Among them, the inlet of the dispensing valve is a conical mouth with a larger upper part and a smaller lower part. The lower end of the conical mouth divides into two branch pipes as the two outlets of the dispensing valve. An electronic valve is respectively provided at the connection between the two branch pipes and the conical mouth. The electronic valve is connected to the controller and is opened and closed under the control of the controller.

[0011] The utility model also provides a concrete mixing station, comprising the above-mentioned feeding device capable of adjusting the feeding sequence.

[0012] Furthermore, the concrete mixing station also includes a powder bin, an additive bin, a water bin and a mixer. The outlets of the first waiting hopper, the second waiting hopper, the powder bin, the additive bin and the water bin all lead to the mixer. Various ingredients can be added to the mixer according to specific needs and mixed to obtain concrete with the required proportion.

[0013] Due to the adoption of the above technical scheme, the utility model has the following advantages: the utility model adds a material distribution valve in the mixing station, and uses very few devices to enable the mixing station to adjust the adding sequence of aggregates with different particle sizes.

Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0020] The utility model provides a feeding device with adjustable feeding sequence, comprising a dividing valve 2, a first hopper for material to be fed, a second hopper for material to be fed and a controller; the dividing valve 2 comprises a feeding port and two discharging ports, the feeding port is connected with a conveyor belt 1 for conveying aggregate, the two discharging ports are respectively connected with the first hopper for material to be fed and the second hopper for material to be fed 4, and the dividing valve 2 is controlled by the controller to drop different aggregates into the first hopper for material to be fed and the second hopper for material to be fed 4 respectively.

[0021] The outlet of the first material hopper 3 is provided with an electronic valve, which is connected to a controller and is opened and closed under the control of the controller.

[0022] The outlet of the second material hopper 4 is provided with an electronic valve, which is connected to a controller and is opened and closed under the control of the controller.

[0023] Among them, the feed inlet of the dispensing valve 2 is a conical mouth 21 that is larger at the top and smaller at the bottom. Two branch pipes 22 are respectively separated from the lower end of the conical mouth as the two discharge ports of the dispensing valve. An electronic valve 23 is respectively provided at the connection between the two branch pipes and the conical mouth. The electronic valve is connected to the controller and is opened and closed under the control of the controller.

[0024] Wherein, a sensor is provided at the feed port, and the sensor is electrically connected to the controller. The sensor is used to identify the type of aggregate being fed and transmit the aggregate type to the controller. The controller opens the electronic valve between the first hopper or the second hopper according to the received aggregate type.

[0025] Wherein, the lower ends of the first and second material-waiting hoppers are each provided with an electronic switch, and the electronic switch is turned on or off under the control of a controller.

[0026] When in use, the measured sand and stone aggregates are transported by the conveyor belt to the position dividing valve, and the corresponding aggregates are controlled by the sensor to enter the stone bin (the first waiting hopper) or the sand bin (the second waiting hopper). Then, the time sequence of 3 or 4 aggregates of different particle sizes entering the mixer can be adjusted at any time according to different concrete process requirements.

[0027] like Figure 2 As shown, the utility model also provides a concrete mixing station, including the above-mentioned feeding device with adjustable feeding sequence. The concrete mixing station also includes a powder heavy bin, an additive bin, a water bin and a mixer.
