The movable gangue sorting machine has a vibrating feeding queuing device. When the gangue material falls from the upper space of the inner cavity of the screening cylinder to the lower space and from the screening cylinder to the conveyor belt, the gangue material is suspended in the air, so that the pressure on the spring is reduced.

When the gangue material falls on the screening cylinder and the gangue material conveyor, the pressure on the spring increases. Therefore, in the process of reciprocating feeding, the spring contracts back and forth, so that the gangue material conveyor and the screening cylinder rise and fall back and forth, thereby vibrating and screening the gangue material.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example: Refer to Figure 1-Figure 8A movable coal gangue separator vibrating feeding queuing device comprises a mobile base, and also comprises: a coal gangue material conveyor fixedly mounted on the mobile base; a second mounting plate 9 fixedly mounted on the coal gangue material conveyor; a screening cylinder 10 rotatably arranged on the second mounting plate 9, the screening cylinder 10 is provided with screening holes 11, and the diameter of the screening holes 11 changes from small to large from the feeding end to the other end of the screening cylinder 10; a spiral blade 12 fixedly connected to the screening cylinder 10, when the screening cylinder 10 rotates, the spiral blade 12 drives the coal gangue material in the screening cylinder 10 to move from the feeding end to the other end.

[0021] The screening holes 11 are provided with at least three specifications, and at least 5-25 of each group of specifications in the same row are provided, which can be arranged according to the overall length of the screening cylinder 10 .

[0022] In this embodiment, by driving the screening drum 10 to rotate, the gangue materials falling into the screening drum 10 are pushed by the spiral blades 12 and move toward the direction of the screening drum 10 under the action of the spiral blades 12. In this process, gangue materials of different sizes fall onto the gangue material conveyor through the corresponding screening holes 11.

[0023] To sum up, in this embodiment, the vibrating feeding queuing device can sort and arrange coal gangue material blocks of different sizes when queuing and feeding coal gangue materials, so that coal gangue materials of different specifications are neatly arranged in the same queue, thereby avoiding small materials from being covered by large materials, thereby improving the accuracy of subsequent sorting.

[0024] Reference Figure 6 and Figure 7 A lifting plate 13 is fixedly mounted on the inner wall of the screening drum 10, and the lifting plate 13 is cross-arranged with the spiral blade 12. When the screening drum 10 rotates, the lifting plate 13 lifts the coal gangue material to the top of the inner cavity of the screening drum 10 and drops it.

[0025] When the screening drum 10 rotates, the lifting plate 13 lifts the coal gangue materials that have not fallen, so that the coal gangue materials follow the screening drum 10 to rotate to the upper chamber in the inner cavity of the screening drum 10, and then fall under the action of gravity. The fallen coal gangue materials collide with the coal gangue materials at the bottom, the lifting plate 13 and the spiral blade 12, so that the dust on the large coal gangue materials falls off and the edges and corners on the large coal gangue materials are broken, thereby preventing the large coal gangue from falling through the screening drum 10 due to the sharp parts such as the edges and corners being too long, and the lifting plate 13 lifts the coal gangue materials. The materials are lifted to the top of the inner cavity of the screening drum 10 and fall. In this process, the mutual collision between the materials and the collision between the materials and the inner wall of the screening drum 10 are helpful to remove the dust on the surface of the coal gangue materials, improve the cleanliness of the materials, and thus improve the accuracy of subsequent identification. Large coal gangue materials can also be broken due to the collision. The coal gangue materials that fall will be redistributed. Smaller materials can pass through the subsequent screening holes 11 more easily, while larger materials continue to be pushed to the other end of the screening drum 10 by the spiral blades 12, further promoting the classification of materials.

[0026] Reference Figure 1 and Figure 2 The mobile base includes a base frame 1, a first motor 2 is fixedly installed at the bottom of the base frame 1, wheels 3 are rotatably installed on the base frame 1, the first motor 2 is fixedly connected to the wheels 3, and four groups of the first motor 2 and the wheels 3 are symmetrically arranged on the top of the base frame 1. During the movement, the speed and direction of the first motor 2 can be controlled to realize the forward, backward, turning and other actions of the device, so that the device can be flexibly moved in different working environments.

[0027] Reference Figure 1-Figure 4 and Figure 8 The coal gangue material conveyor includes a first mounting plate 4 fixedly mounted on the top of a base frame 1, a mounting roller 5 is rotatably connected to the first mounting plate 4, a conveyor belt 7 is rotatably connected to the mounting roller 5, a slide bar 29 is fixedly connected to the bottom of the first mounting plate 4, the slide bar 29 is slidably connected to the base frame 1, a spring 30 is sleeved on the slide bar 29, and both ends of the spring 30 are respectively in contact with the base frame 1 and the bottom of the first mounting plate 4.

[0028] During use, when the gangue material falls from the upper space of the inner cavity of the screening drum 10 to the lower space and from the screening drum 10 to the conveyor belt 7, the gangue material is suspended in the air, so that the pressure on the spring 30 is reduced. At this time, the spring 30 rebounds, so that the gangue material conveyor and the screening drum 10 rise. When the gangue material falls on the screening drum 10 and the gangue material conveyor, the pressure on the spring 30 increases. Therefore, in the process of reciprocating material feeding, the spring 30 contracts back and forth, so that the gangue material conveyor and the screening drum 10 rise and fall back and forth, thereby vibrating and screening the gangue material.

[0029] In summary, during the continuous feeding process of the coal gangue material, the spring 30 reciprocates and contracts and rebounds, forming a reciprocating lifting and lowering vibration effect, which promotes further classification and separation of the coal gangue material in the screening cylinder 10 and improves the screening efficiency. At the same time, the vibration can also promote the uniform distribution and rapid movement of the coal gangue material on the conveyor belt 7, reducing blockage and accumulation.

[0030] When it is necessary to further improve the vibrating screening effect, a vibrating motor may be installed at the bottom of the first mounting plate 4 .

[0031] Reference Figure 1-Figure 8 A separation groove 8 is provided on the conveyor belt 7, and the separation groove 8 is conical.

[0032] When the gangue material falls from the bottom of the screening cylinder 10, it can fall into the dividing groove 8, and a piece of gangue material falls into each dividing groove 8, thereby ensuring the distance between adjacent gangue materials, improving the subsequent sorting accuracy, and avoiding the sorting equipment grabbing multiple pieces of gangue material at one time.

[0033] Reference Figure 1-Figure 2 and Figure 4 A second motor 6 is fixedly mounted on the side wall of the first mounting plate 4, and the output end of the second motor 6 is fixedly connected to the mounting roller 5. The mounting roller 5 is transmission-connected to the screening drum 10 through a pulley assembly 14, and the transmission ratio between the pulley connected to the screening drum 10 and the pulley connected to the mounting roller 5 is 1:3-10.

[0034] During use, the second motor 6 is started, and the second motor 6 drives the installation roller 5 to rotate, and the installation roller 5 drives the transmission belt 7 to rotate, thereby transmitting the coal gangue material. At the same time, the installation roller 5 drives the screening drum 10 to rotate through the pulley assembly 14. Under the differential speed ratio between the two pulleys of different diameters in the pulley assembly 14, the transmission belt 7 drives the coal gangue material to move quickly, and the screening drum 10 rotates slowly, thereby reducing the speed at which the coal gangue material falls, thereby making the distance between the front and rear distributed coal gangue materials longer, improving the sorting accuracy of the subsequent coal gangue material sorting machine, and reducing the possibility of misgrabbing or over-grabbing by the sorting equipment. The combination of the rapid movement of the transmission belt 7 and the slow rotation of the screening drum 10 realizes the rapid transmission and orderly distribution of the material.

[0035] Reference Figure 1-Figure 5A first dust cover 19 is fixedly installed on the top of the first mounting plate 4, a second dust cover 25 is sleeved on the screening cylinder 10, a discharge hole is opened at the bottom of the second dust cover 25, an exhaust pipe 20 is fixedly installed on the side wall of the first dust cover 19, the exhaust pipe 20 is connected to the inside of the first dust cover 19, a powder discharge pipe 21 is fixedly connected to the bottom of the first dust cover 19, a one-way valve is provided at the output end of the powder discharge pipe 21, a fourth motor 23 is fixedly connected to the exhaust pipe 20, and the output shaft of the fourth motor 23 extends to the exhaust pipe 20 and is fixedly connected to the fan blade 24; a filter screen 22 is fixedly installed in the exhaust pipe 20, and the filter screen 22 is inclined; a diverter box 26 is fixedly connected to the top of the second dust cover 25, and the air inlet end of the diverter box 26 is connected to the exhaust end of the exhaust pipe 20 through a ventilation pipe 27, and an electric heating net 28 is provided in the ventilation pipe 27.

[0036] When in use, the fourth motor 23 is started, and the fourth motor 23 drives the fan blades 24 to rotate. The rotation of the fan blades 24 makes the air pressure in the internal space of the first dust cover 19 lower than the external air pressure. Under the action of the pressure difference, the gas flows, and the flowing gas carries the dust into the exhaust pipe 20. Under the action of the filter 22, the dust remains in the exhaust pipe 20. Under the action of vibration and gravity, the dust falls from the filter 22 to the powder discharge pipe 21, and then is discharged along the powder discharge pipe 21. The filtered airflow enters the ventilation pipe 27, contacts the heated electric heating net 28 to absorb heat to form hot air, and the hot air enters the diversion box 26 for diversion, and then is sprayed into the second dust cover 25, and is sprayed into the inside of the screening cylinder 10 through the screening hole 11 at the top of the screening cylinder 10, and then contacts the coal gangue material in the screening cylinder 10 to dry the coal gangue material.

[0037] In summary, in this embodiment, the dust cover and the filter 22 are used in combination to effectively reduce dust emission and environmental pollution; Drying process is carried out simultaneously with material transmission, screening and other processes, which shortens the overall processing time and improves work efficiency; The drying process removes excess water and moisture from the gangue material, improves the dryness and stability of the material, and is beneficial to subsequent sorting, processing and other processes; In addition, the airflow blown downward from the top of the screening cylinder 10 can also blow away the coal gangue materials blocked in the screening holes 11, thereby improving the smoothness of the screening holes 11.

[0038] Reference Figure 1 and Figure 4The side wall of the second mounting plate 9 is slidably connected with a feed hopper 15, and a through hole connected to the feed hole on the screening cylinder 10 is opened on the side wall of the feed hopper 15. A third motor 16 is fixedly installed on the outer wall of the first dust cover 19, and a screw rod 17 is fixedly connected to the output end of the third motor 16. A connecting block 18 is threadedly connected to the screw rod 17, and the connecting block 18 is fixedly connected to the outer wall of the feed hopper 15.

[0039] The third motor 16 is started, and the third motor 16 drives the screw rod 17 to rotate. The screw rod 17 drives the feed hopper 15 to move up and down through the connecting block 18, so as to facilitate the feeding of coal gangue materials at different heights and improve the flexibility of feeding.

[0040] A method for queuing coal gangue sorting feeding includes the following steps: Step 1: Pour the coal gangue material into the horizontally arranged screening drum 10 and rotate the screening drum 10; Step 2: Move the conveyor belt 7, and make the rotation speed of the conveyor belt 7 greater than the rotation speed of the screening drum 10; Step 3: The spiral blade 12 drives the gangue material to move, so that the gangue material passes through the screening holes 11 arranged from small to large in sequence, and the corresponding volume of gangue material is discharged to the separation groove 8 through the holes of corresponding diameters; Step 4: The lifting plate 13 lifts the large coal gangue material, so that the coal gangue material moves to a high place and falls to collide with the coal gangue material at the bottom, and the coal gangue material is discharged through the screening hole 11 at the bottom of the screening cylinder 10.
