Description

Technical Field

[0001] The utility model relates to the technical field of coal mine processing, in particular to an automatic gangue discharge mechanism of a dry separator. Background Art

[0002] If there is too much gangue in the raw coal, it will inevitably cause the ash content of the raw coal to exceed the standard and the coal quality to decline, which will directly affect the coal sales. To address the above problems, it is necessary to remove gangue and reduce ash, improve coal quality, and realize gangue packaging.

[0003] In the current gangue separation method, the mixture of coal and gangue is generally conveyed into the feed port of the dry separator. The TDS intelligent dry separator transmission identification technology is used to digitally identify the parameters of coal blocks and gangue, and high-pressure air is blown by high-speed solenoid valves to achieve efficient separation of coal and gangue.

[0004] However, conveyor belt feeding will cause the coal and gangue mixture to stack. After the stacked coal and gangue mixture enters the dry separator, it interferes with the sorting accuracy of the dry separator, resulting in low separation efficiency of coal and gangue.

[0005] For this reason, we propose an automatic gangue discharge mechanism for dry separator to solve the existing problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problems existing in the background technology and to propose an automatic gangue discharge mechanism for a dry separator.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic gangue discharge mechanism of a dry sorting machine, comprising a bed, a connecting seat, a feeding hopper, a vibrating frame and a homogenizing plate. The upper surface of the bed is elastically connected to the vibrating frame through a spring, and the bottom end of the inner wall of the vibrating frame adopts a slope design. The upper surface of the bed is provided with a connecting seat, and a homogenizing plate is slidably installed on the connecting seat. The homogenizing plate is located at the lower end of the inner wall of the vibrating frame.

[0008] Preferably, a spring is fixed to the lower surface of the vibration frame by bolts, and the bottom end of the spring is fixed to the upper surface of the bed by bolts;

[0009] A vibration motor is installed at the center of the lower surface of the vibration frame.

[0010] Preferably, a fixing block is installed on the upper end of the side wall of the connecting seat, and the other end of the fixing block is installed on the outer wall of the feeding hopper.

[0011] Preferably, a slide groove is provided at the lower end of one side surface of the connecting seat, and a screw rod is rotatably installed in the slide groove;

[0012] A slider is slidably installed in the slide groove, and a threaded hole adapted to the screw rod is opened on the slider;

[0013] The screw rod and the threaded hole are meshed with each other, and a curved rod is installed on the outside of the slider, and a homogenizing plate is fixed on the other end of the curved rod.

[0014] Preferably, a support seat is provided on the lower surface of the bed;

[0015] There are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the bed.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During the use of the automatic gangue discharge mechanism of the utility model dry separator, the coal and gangue mixture conveyed by the conveyor belt enters the feeding hopper and then falls into the vibration frame;

[0018] At this time, the vibration motor drives the vibration frame to vibrate. Under the vibration action, the coal and gangue mixture is evenly distributed in the vibration frame. At the same time, under the action of the inclined surface of the vibration frame, the evenly distributed materials move to the feeding port of the dry separator for subsequent gangue discharge operation;

[0019] When the material falls into the vibration frame, the screw is controlled to rotate, thereby driving the slider to move in the chute. When the homogenizing plate moves back and forth in a straight line, the material pile that has just fallen into the vibration frame is pushed flat, thereby accelerating the vibration homogenization operation of the vibration frame on the material.

[0020] The utility model utilizes the effect of vibration to evenly distribute the mixed material at the feeding port of the intelligent dry separator. At the same time, the homogenization speed of the material in the vibration frame is accelerated by the reciprocating movement design of the homogenizing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-Figure 4 As shown, the utility model proposes an automatic gangue discharge mechanism of a dry separator, comprising a bed 2, a connecting seat 3, a feeding hopper 4, a vibrating frame 6 and a homogenizing plate 8. The upper surface of the bed 2 is elastically connected to the vibrating frame 6 through a spring 7. The bottom end of the inner wall of the vibrating frame 6 adopts a slope design. The upper surface of the bed 2 is provided with a connecting seat 3, and a homogenizing plate 8 is slidably installed on the connecting seat 3. The homogenizing plate 8 is located at the lower end of the inner wall of the vibrating frame 6.

[0030] Based on Example 1:

[0031] During the use of the automatic gangue discharge mechanism of the dry separator of the utility model, the coal and gangue mixture transported by the conveyor belt enters the feeding hopper 4 and then falls into the vibration frame 6;

[0032] At this time, the vibration motor 9 drives the vibration frame 6 to vibrate. Under the vibration action, the coal and gangue mixture is evenly distributed in the vibration frame 6. At the same time, under the action of the inclined surface of the vibration frame 6, the evenly distributed materials move to the feed port of the dry separator.

[0033] When the material falls into the vibration frame 6, the screw 11 is controlled to rotate, thereby driving the slider 12 to move in the chute 10. When the homogenizing plate 8 moves back and forth in a straight line, the material pile that has just fallen into the vibration frame 6 is flattened, thereby accelerating the vibration homogenization operation of the vibration frame 6 on the material.
