Description

Technical Field

[0001] This utility model relates to the technical field of coal gangue sorting, and in particular to a dynamic coal gangue sorting device. Background Technology

[0002] Coal gangue is a solid waste discharged during coal mining and coal washing. It is a blackish-gray rock with low carbon content and harder than coal that is associated with coal seams during coal formation. It is mainly composed of carbonaceous, argillaceous, and sandy shale. It includes gangue from tunneling, gangue extracted from the roof, floor, and interlayers during mining, and gangue picked out during coal washing. Separating coal gangue is a necessary process in coal mining, which can not only reduce washing costs but also improve the grade of finished coal.

[0003] In response to this, Chinese Patent No. CN220922915U proposes a coal gangue sorting device, including a support frame with two side plates symmetrically fixed on the support frame. A conveyor belt device is provided between the side plates. A spray device is provided on the top and one side of the side plates. A feed box is provided above one end of the conveyor belt device. The bottom of the feed box is connected to the top surface of the side plate. A discharge plate is provided at the end of the conveyor belt device away from the feed box. A collection box is placed at the port of the discharge plate.

[0004] This device separates small and large coal gangue particles using a perforated grid conveyor belt. A three-impeller design allows the grid conveyor belt to vibrate slightly up and down, making it easier for small coal gangue particles to pass through the holes, ensuring effective screening and improving screening efficiency. However, the anti-clogging effect is relatively weak. When coal gangue gets stuck in the holes between the grid conveyor belt particles, the slight up-and-down vibrations cannot dislodge it, affecting subsequent coal gangue screening. Therefore, a dynamic coal gangue sorting device is needed. Utility Model Content

[0005] The purpose of this invention is to provide a dynamic coal gangue sorting device to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A dynamic coal gangue sorting device, comprising:

[0008] The processing box has fixed bases on both sides;

[0009] Connection component, the connection component comprising:

[0010] An electric push rod, the bottom end of which is fixedly mounted on one side of a fixed base;

[0011] A connecting rod, the inner side of which is fixedly mounted on the telescopic end of the electric push rod;

[0012] A connecting block, one side of which is rotatably mounted on one side of the connecting rod:

[0013] A connecting frame, one side of the bottom end of which is slidably disposed on the top of the connecting block;

[0014] A screening plate, the outer wall of which is attached to the inner side of the connecting frame, a number of screening holes are opened at the top of the screening plate, and a vibration motor is fixedly installed on the side of the bottom end of the screening plate.

[0015] The material-blocking assembly includes:

[0016] Mounting plate, the outer wall of which is embedded in one side of the processing box;

[0017] A material-stopping rod, one end of which is fixedly mounted on one side of the mounting plate, and the material-stopping rod is located inside the processing box.

[0018] Optionally, a plurality of the screening holes are arranged in an array, and the diameter of the screening holes is larger than the outer diameter of the abutment rod.

[0019] Optionally, the outer wall of the connecting rod extends through one side of the processing box.

[0020] Optionally, the connection component further includes:

[0021] The slider has its bottom end fixedly mounted on the top of the connecting block, and its outer wall is slidably connected to the bottom end of the connecting frame.

[0022] Optionally, a first collection box is installed on the other side of the processing box, and a second collection box is installed at the bottom of the processing box.

[0023] Optionally, a rod seat is fixedly provided on the outer wall of the electric push rod, and one side of the rod seat is fixedly disposed on one side of the processing box.

[0024] Optionally, it also includes a buffer component, the buffer component comprising:

[0025] The vertical rod has its outer wall extending through the inner bottom end of the connecting frame, and its top end is fixedly connected to the side of the bottom end of the screening plate.

[0028] Optionally, the top end of the spring is fixedly connected to the bottom end of the screening plate, and the bottom end of the spring is fixedly connected to the inner bottom end of the connecting frame.

[0029] Compared with the prior art, the beneficial effects of this utility model are:

[0030] Equipped with a material-stopping rod, an electric push rod, and a screening plate, when coal gangue gets stuck in the screening hole, the electric push rod is activated. The electric push rod drives the connecting rod forward, which in turn drives one end of the connecting frame to rotate downward through the connecting block. This, in turn, drives the screening plate to rotate. When the coal gangue in the screening hole comes into contact with the material-stopping rod, the electric push rod continues to work, and the material-stopping rod pushes the coal gangue out of the screening hole. This method can improve the anti-clogging effect of the screening plate and prevent the screening plate from being blocked, thus affecting the screening effect of coal gangue.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] Given that the current technology has a relatively poor anti-clogging effect, when coal gangue gets stuck in the holes between the grid conveyor belts, small up-and-down bumps cannot dislodge it, which will affect the subsequent coal gangue screening effect.

[0049] like Figure 1-6 As shown, this utility model embodiment provides a dynamic coal gangue sorting device, including:

[0050] Processing box 1, with fixed bases 2 on both sides of processing box 1;

[0051] The processing box 1 is used for screening coal gangue, and the fixed base 2 is used for connection and support.

[0052] Connection component 3, connection component 3 includes:

[0053] Electric push rod 31, the bottom end of which is fixedly mounted on one side of the fixed base 2;

[0054] Connecting rod 32, the inner side of which is fixedly mounted on the telescopic end of electric push rod 31;

[0056] The connecting frame 34 has one side of its bottom end slidably mounted on the top of the connecting block 33;

[0057] The overall shape of the connecting frame 34 is U-shaped;

[0058] One end of each side of the connecting frame 34 is connected to the bearings on both sides of the inner wall of the processing box 1, and the electric push rod 31 is used to provide the driving force required for the connecting frame 34 to rotate downward.

[0059] The outer wall of the screening plate 4 is attached to the inner side of the connecting frame 34. Several screening holes 41 are opened at the top of the screening plate 4, and a vibration motor 42 is fixedly installed on the side of the bottom end of the screening plate 4.

[0060] The screening plate 4, in conjunction with the screening holes 41, is used to screen coal gangue of different sizes. The vibration motor 42 is a YZO series motor, such as YZO-50-6. The vibration motor 42 is used to provide the vibration force required for the up and down vibration screening of the screening plate 4.

[0061] Material-blocking component 5, which includes:

[0062] Mounting plate 51, the outer wall of mounting plate 51 is embedded in one side of processing box 1;

[0063] The material-stopping rod 52 has one end fixedly mounted on one side of the mounting plate 51, and the material-stopping rod 52 is located inside the processing box 1;

[0064] The mounting plate 51 is located on the outside of the processing box 1 on one side and on the inside of the processing box 1 on the other side. The number and arrangement of the abutment rods 52 are adapted to the number and arrangement of the screening holes 41.

[0065] Furthermore, a plurality of screening holes 41 are arranged in an array, and the diameter of the screening holes 41 is larger than the outer diameter of the abutment rod 52;

[0066] Furthermore, the outer wall of the connecting rod 32 penetrates one side of the processing box 1;

[0067] The connecting rod 32 is L-shaped, and its outer wall is slidably connected to one side of the processing box 1.

[0068] Furthermore, the connection component 3 also includes:

[0069] The bottom end of the slider 35 is fixedly set at the top end of the connecting block 33, and the outer wall of the slider 35 is slidably connected to the bottom end of the connecting frame 34.

[0070] The slider 35 is T-shaped and is used to limit the movement of the connecting block 33, so that it can move horizontally along the bottom edge of the connecting frame 34. The two sides of the bottom of the connecting frame 34 are provided with grooves that are adapted to the slider 35.

[0071] Furthermore, a first collection box 11 is installed on the other side of the processing box 1, and a second collection box 12 is installed at the bottom of the processing box 1;

[0072] The other side and bottom of the processing box 1 are provided with discharge ports, and the first collection box 11 and the second collection box 12 are respectively located below the two discharge ports. They are used to collect the screened coal gangue. The top of the processing box 1 is provided with a feed port.

[0073] Furthermore, a rod seat 7 is fixedly provided on the outer wall of the electric push rod 31, and one side of the rod seat 7 is fixedly provided on one side of the processing box 1;

[0074] The rod holder 7 is used to connect and support the electric actuator 31, thereby improving its overall stability.

[0075] Working principle: Coal gangue is fed into the processing box 1. After falling onto the screening plate 4, the vibrating motor 42 is turned on. The vibrating motor 42 drives the screening plate 4 to vibrate, thereby screening the coal gangue. The screened coal gangue is collected through the first collection box 11 and the second collection box 12. When coal gangue gets stuck in the screening hole 41 of the screening plate 4, the electric push rod 31 is activated. The electric push rod 31 drives the connecting rod 32 to move forward, connecting... The rod 32 moves forward, causing the connecting block 33 to move along the bottom of the connecting frame 34, thereby causing one end of the connecting frame 34 to rotate downward. The rotation of the connecting frame 34 causes the screening plate 4 to rotate. When the coal gangue in the screening hole 41 comes into contact with the abutment rod 52, as the electric push rod 31 continues to work, the coal gangue is pushed out of the screening hole 41 under the action of the abutment rod 52. In this way, the anti-clogging effect of the screening plate 4 can be improved, and the screening effect of the coal gangue can be avoided by the screening plate 4 being blocked.

[0076] Specifically, such as Figure 1-6 As shown, it also includes:

[0077] Buffer component 6, which includes:

[0078] The vertical rod 61 has its outer wall penetrating the inner bottom end of the connecting frame 34, and its top end is fixedly connected to the side of the bottom end of the screening plate 4.

[0079] The vertical rod 61 is slidably connected to the inner bottom end of the connecting frame 34, and a rubber sleeve with damping and elastic functions is bonded between the vertical rod 61 and the connecting frame 34, so that the spring 62 will not continuously expand and contract after contraction. There are four vertical rods 61, which are respectively fixedly installed on the four sides of the bottom end of the screening plate 4.

[0080] Spring 62 is sleeved on the outer wall of vertical rod 61;

[0081] Limiting block 63, the top of which is fixedly set at the top of vertical rod 61;

[0082] The limiting block 63 is used to limit the movement of the vertical rod 61 to prevent it from coming off the connecting frame 34.

[0083] Furthermore, the top end of the spring 62 is fixedly connected to the bottom end of the screening plate 4, and the bottom end of the spring 62 is fixedly connected to the inner bottom end of the connecting frame 34.

[0084] Working principle: When the vibrating motor 42 drives the screening plate 4 to vibrate and screen, the vibration of the screening plate 4 generates a force on the spring 62. Under the elastic action of the spring 62, the force is buffered, thereby reducing the force between the screening plate 4 and the connecting frame 34.

[0085] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
