Description

Technical Field

[0001] The present application belongs to the technical field of unloading equipment, and more specifically, to a bidirectional single-sided rotating plow-type unloader. Background Art

[0002] The plow discharger is a kind of unloading equipment installed on the belt conveyor, which is generally divided into double-sided plow discharger and single-sided plow discharger. Double-sided plow discharger can discharge materials to both sides of the conveyor belt at the same time, while single-sided plow discharger can only discharge materials to the fixed side of the conveyor belt.

[0003] However, sometimes it is necessary to discharge to one side of the conveyor belt within a period of time, and to discharge to the other side of the belt conveyor within another period of time. The existing equipment cannot meet this working condition. The usual solution is to set two single-sided plow dischargers along the conveyor belt in sequence, fixed to one side of the corresponding belt conveyor respectively, and to achieve the purpose of discharging on both sides of the conveyor belt as needed on a conveyor belt by operating the two single-sided dischargers separately. This will cause equipment waste and too many plow dischargers at one unloading position, which is prone to unloading failures and safety hazards. Utility Model Content

[0006] In one embodiment, the positioning lock comprises an electromagnet, a positioning pin and a positioning frame, the positioning pin is movably arranged on the positioning frame, and one end of the positioning pin is attracted to or separated from the electromagnet.

[0007] In one embodiment, one end of the vertical lifting frame is slidably arranged on the frame, and the other end is provided with two positioning locks.

[0008] In one embodiment, the roller assembly is lifted and lowered on the frame, a connecting rod bracket is rotatably provided on the frame, the middle of the connecting rod bracket is rotatably provided on the frame, one end of the connecting rod bracket is fixedly connected to the vertical lifting frame, and the other end is movably connected to one end of the roller assembly; when the vertical lifting frame descends, one end of the roller assembly is synchronously driven to rise through the connecting rod bracket; when the vertical lifting frame rises, one end of the roller assembly is synchronously driven to descend through the connecting rod bracket.

[0009] In one embodiment, the vertical lifting frame is slidably arranged on the column of the frame through two sliding frames, and a plurality of rollers that are in rolling contact with the surface of the column are arranged in the sliding frame.

[0010] In one embodiment, the discharge surface of the single-sided rotary plowshare is provided with a thickened plate.

[0011] In one embodiment, the rotating electrical machine is a reduction motor.

[0012] The beneficial effect of the bidirectional single-sided rotary plow type unloader provided in the present application is that the rotary motor can drive the single-sided rotary plowshare to rotate 360°, and utilize the positioning lock to ensure that the single-sided rotary plowshare stays stably in the current position, and four unloading positions can be realized on the conveyor belt, thereby achieving the purpose of bidirectional single-sided unloading.

[0025] like Figure 1-Figure 5 As shown, a bidirectional single-sided rotary plow discharger provided in an embodiment of the present application is now described. The bidirectional single-sided rotary plow discharger comprises: a frame 1, a vertical lifting frame 2, an electric push rod 3, a rotary motor 4, a single-sided rotary plowshare 6 and a positioning lock 9.

[0026] The frame 1 includes four columns 11 and a horizontal frame 12 arranged on the top of the four columns 11. The vertical lifting frame 2 is slidably arranged on the columns 11, and the electric push rod 3 is fixed on the horizontal frame 12. The piston end of the electric push rod 3 is fixedly connected to the vertical lifting frame 2 below, and the electric push rod 3 is used to drive the vertical lifting frame 2 to slide up and down. The rotating motor 4 is fixed on the vertical lifting frame 2. The rotating motor 4 is connected to the rotating shaft 5. The rotating shaft 5 is fixed to the middle position of the single-sided rotating plowshare 6. When the rotating motor 4 is working, it can drive the rotating shaft 5 to rotate, thereby driving the single-sided rotating plowshare 6 to rotate, and realizing the 360° rotation of the single-sided rotating plowshare 6. The rotating motor 4 is preferably a reduction motor.

[0027] A roller assembly 7 is provided on the frame 1 below the single-sided rotary plowshare 6, and the roller assembly 7 is used to support the conveyor belt 8; variable angle roller groups 10 are provided at both ends of the frame 1, which are also used to support the conveyor belt 8. A positioning lock 9 is provided on the vertical lifting frame 2 to keep the single-sided rotary plowshare 6 in the current position; when the single-sided rotary plowshare 6 rotates to the right position, the positioning lock 9 can keep the single-sided rotary plowshare 6 from rotating, ensuring that it performs single-sided unloading of the conveyor belt at the current position.

[0028] like Figure 2 As shown, in the present embodiment, the positioning lock 9 comprises an electromagnet 91, a positioning latch 92 and a positioning frame 93. The positioning frame 93 and the electromagnet 91 are both fixed on the vertical lifting frame 2. The positioning frame 93 is located below the electromagnet 91. The positioning latch 92 is movably arranged on the positioning frame 93. One end of the positioning latch 92 is attracted to or separated from the electromagnet 91. When the electromagnet 91 is powered off, the magnetic attraction disappears, and the positioning latch 92 falls under the action of its own gravity, thereby blocking the side of the unilateral rotating plowshare 6 and preventing the unilateral rotating plowshare 6 from rotating. When the electromagnet 91 is powered on, a strong magnetic attraction is generated to move the positioning latch 92 upward, so that the positioning latch 92 cancels the blocking effect on the unilateral rotating plowshare 6. The unilateral rotating plowshare 6 can be rotated to the next unloading position under the action of the rotating motor 4.

[0029] In this embodiment, the vertical lifting frame 2 is a rectangular frame structure. One end of the vertical lifting frame 2 is slidably set on the two columns 11 of the frame 1, and the other end is provided with two positioning locks 9. The purpose of the two positioning locks 9 is to realize that the single-sided rotating plowshare 6 can have four unloading positions.

[0030] In this embodiment, the roller assembly 7 includes a swing bracket and a roller bracket which is lifted and arranged on the swing bracket. A plurality of rollers are arranged on the roller bracket. Both ends of the roller bracket are lifted and arranged on the swing bracket by two lifting cylinders. One end of the swing bracket is hinged on the frame, and the other end is a movable end and is connected to the connecting bracket 13. Specifically, a connecting rod bracket 13 is rotatably arranged on the frame 1. The middle of the connecting rod bracket 13 is rotatably arranged on the column 11 of the frame 1, one end of which is fixedly connected to the vertical lifting frame 2, and the other end is movably connected to one end of the roller assembly 7. When the vertical lifting frame 2 descends, one end of the roller assembly 7 is synchronously driven to rise through the connecting rod bracket 13 to improve the contact between the single-sided rotating plowshare 6 and the conveyor belt 8. When the vertical lifting frame 2 rises, one end of the roller assembly 7 is synchronously driven to descend through the connecting rod bracket 13. Figure 5 As shown, specifically, a guide long groove 131 is provided at the other end of the connecting rod bracket 13, and a guide shaft 71 is provided on the swing bracket of the roller assembly 7. The guide shaft 71 is slidably set in the guide long groove 131. Through the cooperation of the guide shaft 71 and the guide long groove 131, one end of the roller assembly 7 can be lifted and lowered.

[0031] In this embodiment, if Figure 1 and Figure 4 As shown, the vertical lifting frame 2 is slidably arranged on the column 11 of the frame 1 through two sliding frames 14, and a plurality of rollers 15 are provided in the sliding frame 14 to roll in contact with the surface of the column 11. The cross section of the column 11 is an I-shaped column, and each sliding frame 14 is provided with at least four rollers 15 to roll in contact with the four side surfaces of the column 11 to ensure the smoothness of the vertical lifting frame 2 sliding up and down.

[0032] In this embodiment, a thickened plate 63 is provided on the discharge surface of the single-sided rotary plowshare 6 . The purpose of the thickened plate 63 is to increase the durability of the single-sided rotary plowshare 6 .

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
