Description

Core sand filling device

Technical Field

The utility model relates to a material supply equipment technical field especially relates to a core sand filling device.

Background

The sand adding device of the core making machine is small in size of the funnel, the amount of sand in each bag is far larger than the volume of the funnel, and in order to supply sand materials in time, workers need to add sand to the funnel frequently, so that the labor intensity of the workers is increased, and the production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art not enough, and provide a core sand filling device, its top adding sand funnel increases a core sand storehouse, once adds sand and just can use for a long time to workman's intensity of labour has alleviateed greatly.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a core sand filling device, includes core sand funnel and controller, the exit linkage of core sand funnel has screw conveyer, screw conveyer's exit linkage has negative pressure pipe, the controller with screw conveyer electricity is connected, the top of core sand funnel is provided with core sand storehouse, the bottom in core sand storehouse is provided with the shakeout mouth, the shakeout mouth is located directly over the core sand funnel, the shakeout mouth is provided with the gate valve of control core sand falling speed.

Furthermore, the side of the core sand silo is provided with a ladder convenient for workers to add sand.

Further, the gate valve is provided with a driving device for controlling the opening and closing amount of the gate valve, the core sand funnel is provided with a detection device for detecting the residual sand of the core sand funnel, and the driving device and the detection device are electrically connected with the controller.

The utility model has the advantages that: the utility model provides a core sand filling device, its includes core sand funnel and controller, the exit linkage of core sand funnel has screw conveyer, screw conveyer's exit linkage has negative pressure pipe, the controller with screw conveyer electricity is connected, the top of core sand funnel is provided with core sand storehouse, the bottom in core sand storehouse is provided with the shakeout mouth, the shakeout mouth is located directly over the core sand funnel, the shakeout mouth is provided with the gate valve of control core sand falling speed. The utility model discloses once add sand can use for a long time, need not the workman and frequently adds sand to greatly reduced workman's intensity of labour.

Detailed Description

The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.

As shown in fig. 1, the core sand filling device of this embodiment includes a core sand funnel 1 and a controller 2, an outlet of the core sand funnel 1 is connected with a screw conveyer 3, an outlet of the screw conveyer 3 is connected with a negative pressure pipe 4, the controller 2 is electrically connected with the screw conveyer 3, a core sand silo 5 is arranged above the core sand funnel 1, a shakeout opening 6 is arranged at the bottom of the core sand silo 5, the shakeout opening 6 is located directly above the core sand funnel 1, and the shakeout opening 6 is provided with a gate valve 7 for controlling the falling speed of the core sand.

When the device is used, the negative pressure machine sucks away core sand in the negative pressure pipe 4 and feeds back the core sand to the controller 2, the controller 2 controls the spiral conveyer 3 to work to convey the core sand in the core sand hopper 1 to the negative pressure pipe 4, and the core sand conveying amount of the spiral conveyer 3 can be preset every time, namely the number of revolutions of the spiral conveyer 3 in each work is set, so that quantitative sand supply is realized; the gate valve 7 is provided with a driving device 9 for controlling the opening and closing amount of the gate valve 7, the core sand funnel 1 is provided with a detection device 10 for detecting the residual sand of the core sand funnel 1, and the driving device 9 and the detection device 10 are both electrically connected with the controller 2; the detection device 10 detects the core sand allowance inside the core sand funnel 1, namely detects the weight of the core sand funnel 1 and feeds back the core sand allowance to the controller 2, when the core sand allowance inside the core sand funnel 1 is not enough, the controller 2 controls the driving device 9 to start, so that the gate valve 7 is opened, and the core sand of the core sand bin 5 falls into the core sand funnel 1.

The utility model discloses, the workman can once only a large amount of core sand are added to core sand storehouse 5, and the during operation, equipment can automatic operation, need not the workman and operate, generally add core sand and can satisfy and use one day to greatly reduced workman's intensity of labour, and improved work efficiency.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
