Abstract

The invention discloses an automatic overturning and coal-blending device. The automatic overturning and coal-blending device comprises a base support rack, a coal storage hopper, a weighing hopper and a transferring hopper, wherein four hydraulic support rods are arranged at the exterior of the weighing hopper and are connected to an overturning flat plate; a weighing device facing the bottom of the weighing hopper is arranged at the middle part of the overturning flat plate; a hydraulic cylinder bracket is arranged below a horizontal support plate; a hydraulic telescopic cylinder connected with the bottom of the overturning flat plate is arranged on the hydraulic cylinder bracket; a controller is arranged on the hydraulic cylinder bracket. By virtue of the manner, the weighing device of the automatic overturning and coal-blending device is used for sending signals to the controller when coal received in the weighing hopper reaches specified weight and controlling the hydraulic telescopic cylinder to contract so as to enable the weighing hopper to overturn; the weighted coal is instantly poured into the transferring hopper to be transported outwards. The automatic overturning and coal-blending device is high in working efficiency and automatic in operation; much labor and plenty of material resources are saved.

Example Embodiment

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0013] see figure 1 , the embodiment of the present invention includes:
[0014] An automatic overturning coal blending device, comprising: a basic support frame 1, a coal storage hopper 2, a weighing hopper 3 and a transfer hopper 4, the coal storage hopper 2 is arranged on the top of the basic support frame 1, and the weighing hopper 3 It is arranged below the discharge port of the coal storage hopper 2, the transfer hopper 3 is arranged obliquely below the weighing hopper 3, a horizontal support plate 11 is arranged on the inside of the basic support frame 1, and the bottom of the weighing hopper 3 An overturning flat plate 8 is provided, and one side of the overturning flat plate 8 is hinged with a horizontal support plate 11. Four hydraulic struts 10 are arranged outside the weighing hopper 3 to connect with the overturning flat plate 8. A weighing device 13 pointing to the bottom of the weighing hopper 3 is provided at the middle part of the overturning plate 8, and a hydraulic cylinder support 12 is provided below the horizontal support plate 11, and a hydraulic cylinder support 12 is provided on the hydraulic cylinder support 12 to match the overturning plate 8. The hydraulic telescopic cylinder 7 connected at the bottom, the hydraulic pump 6 corresponding to the hydraulic telescopic cylinder 7 is arranged in the hydraulic cylinder bracket 12, and a controller 9 is arranged on the hydraulic cylinder bracket 12, and the controller 9 and The electromagnetic valve on the hydraulic pump 6 is connected to control the expansion and contraction of the hydraulic telescopic cylinder 7, the weighing device 13 is connected to the controller 9 to transmit the weight signal, and the bottom outlet of the coal storage hopper 2 is provided with an electromagnetic valve. The unloading valve 21, the controller 9 is connected with the electromagnetic unloading valve 21 to control its opening and closing.
[0015] The feature of the automatic overturning coal blending device is that the overturning of the weighing hopper 3 is used to realize rapid unloading, and the overturning plate 8 is overturned under the drive of the hydraulic telescopic cylinder 7 .
[0016] Further, the transfer hopper 4 is located below the opening where the coal flows out after the weighing hopper 3 is turned down with the turning plate 8 . The coal flows directly from the coal storage hopper 2 into the weighing hopper 3, and the weighing device 3 sends a signal to the controller 9 when the coal in the weighing hopper 3 receives a specified weight, and the controller 9 closes the electromagnetic discharge valve 21 to stop the storage. Coal hopper 2 is fed, and the hydraulic telescopic cylinder 7 is controlled to shrink, so that the weighing hopper 3 is turned over, and the weighed coal is immediately poured into the transfer hopper 4 for external transportation, and the weighing hopper 3 is then restored to the level, and the process continues Weighing and blending coal, the unloading speed is fast, and the waiting time is less, which realizes the transportation to the outside while weighing, the work efficiency is high, and a lot of manpower and material resources are saved.
[0017] Further, a conveyor belt 5 is provided below the transfer hopper 4 . The conveyor belt 5 transports the coal to the outside and mixes it with the coal at other combustion points to realize the coal blending work.
[0018] To sum up, the automatic turning coal blending device pointed out by the present invention realizes coal weighing and fast unloading, automatic operation, and high working efficiency.
[0019] The above descriptions are only examples of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the description of the present invention, or directly or indirectly used in other related technical fields, shall be The same reasoning is included in the patent protection scope of the present invention.
