[0001] The present invention relates to the technical field of screening equipment, and in particular to a mobile high-frequency screening station and an intelligent adjustment system thereof. Background Art

[0002] Screening technology is widely used in coal, metallurgy, petroleum, chemical industry, building materials, environmental protection and other fields. It is a key link in the production process of most enterprises. It is responsible for grading, dehydration, desludging and de-mediation. The commonly used screening equipment is a vibrating screen. A screen is set inside the equipment, and a vibration motor is set on the equipment. The vibration motor drives the equipment and the material falling on the screen to vibrate, so that the material is screened through the screen.

[0003] In the related technologies, in the fields of mining and other fields, it is necessary to continuously screen ores and other materials on a large scale, and it is necessary to establish a screening station composed of vibrating screens for screening. Most of them are done by setting up a conveyor belt to transport materials into the top of the screening equipment with a vibrating screen structure. The screening equipment is set at an angle and screens the materials through vibration and the gravitational potential energy of the materials.

[0004] Most of the existing screening stations are fixed screening stations, which require the construction of foundations and the assembly of various components, making them very inconvenient to use. Summary of the invention

[0005] In order to improve the convenience of use, the present application provides a mobile high-frequency screening station and an intelligent adjustment system thereof.

[0006] The mobile high-frequency screening station and its intelligent adjustment system provided in this application adopt the following technical solutions: A mobile high-frequency screening station comprises a machine body, a conveyor belt and a screening device, wherein the conveyor belt and the screening device are arranged on the machine body, the machine body is rotatably provided with a plurality of moving wheels, the machine body is slidably provided with a plurality of legs, the machine body is provided with a supporting driving member, the supporting driving member is used to drive the legs to move, the conveyor belt is used to transport materials into the screening device, and the screening device is used to perform screening.

[0007] By adopting the above technical solution, the machine body can be moved by the moving wheels to drive the movement of the entire screening station. At the same time, when screening is required, after the machine body is moved to the screening position by the moving wheels, the support driving member is started to drive the legs to press against the ground and lift the machine body, so that the moving wheels are no longer in contact with the ground. At this time, the material is poured onto the conveyor belt, and the conveyor belt is started to pour the material into the screening equipment, and the screening is carried out by the screening equipment. The operation is simple and convenient, and screening can be carried out without building a foundation and assembling the overall screening station, thereby improving the convenience of use.

[0008] Preferably, a first connecting rod is rotatably arranged on the machine body. The first connecting rod is rotatably connected to the conveyor belt. A second connecting rod is rotatably arranged on the conveyor belt. The second connecting rod is rotatably connected to the screening device. The screening device is rotatably connected to the machine body. The machine body is provided with a lifting driving member for driving the screening device to rotate and lift.

[0009] By adopting the above technical solution, when screening is required, after the machine body stops at the screening position, the supporting feet are raised. At this time, the lifting driving member is started to drive the screening device to rotate and lift, so that the screening device is inclined. At the same time, the screening device drives the conveyor belt to rotate. The conveyor belt is rotationally connected through the first connecting rod and the second connecting rod, thereby completing the lifting. The operation is simple and convenient. The inclined screening device is convenient for screening, improving the convenience of use.

[0010] Preferably, a support rod is rotatably arranged on the screening device. A support block is arranged on the machine body. The support block is provided with a support groove. The support rod is provided with a support sliding rod. The support sliding rod is slidably arranged in the support groove.

[0011] By adopting the above technical solution, when the screening device rotates and lifts, the support rod is synchronously driven to rotate, so that the support sliding rod slides in the support groove of the support block. The screening device is resisted by the support rod, thereby improving the stability of the screening device during use and reducing the possibility of damage to the screening device caused by excessive materials in the screening device during use, improving the durability.

[0012] Preferably, a sliding groove is arranged on the machine body. A sliding plate is arranged in the sliding groove. The support block is arranged on the sliding plate. The screening device is rotatably connected to the sliding plate. The lifting driving member is arranged on the sliding plate. The machine body is provided with a sliding component for driving the sliding plate to slide.

[0013] By adopting the above technical solution, the sliding component can drive the sliding plate to slide out in the sliding groove. When screening is not carried out, the sliding component drives the sliding plate to slide back into the sliding groove, which can reduce the overall length of the machine body, thus facilitating movement and storage. When in use, extending the sliding plate is convenient for the lifting use of the screening device.

[0014] Preferably, the sliding component includes a first sliding gear, a second sliding gear, a first sliding rack and a second sliding rack. The machine body is provided with a first transmission groove communicated with the sliding groove. The first sliding gear and the second sliding gear are both rotatably arranged in the first transmission groove. The first sliding rack is slidably arranged in the first transmission groove and meshes with the first sliding gear. The first sliding rack is connected to the supporting leg. The second sliding rack is arranged on the sliding plate and meshes with the second sliding gear. The first sliding gear is connected to the second sliding gear.

[0015] By adopting the above technical solution, when the outrigger extends, it drives the first sliding rack to slide in the first transmission groove, so as to drive the first sliding gear to rotate. The rotation of the first sliding gear drives the second sliding gear to rotate, thereby pushing the second sliding rack to slide to drive the sliding plate to slide out. When the outrigger retracts, the gear and rack of the sliding assembly cooperate to drive the sliding plate to slide back into the sliding groove. The operation is simple and convenient, the operation steps are simplified, and the convenience of use is improved.

[0016] Preferably, a limiting groove communicating with the first transmission groove is provided on the bottom wall of the sliding groove, and the second sliding rack is inserted into the limiting groove and can move in the limiting groove.

[0017] By adopting the above technical solution, the second sliding rack is clamped into the limiting groove, improving the stability of the sliding of the second sliding rack and the sliding plate.

[0019] By adopting the above technical solution, when the screening equipment is lifted or lowered, during the sliding process of the support sliding rod, it abuts against the locking rod and drives the locking rod to rotate, so that the support sliding rod moves to the other end of the locking rod and continues to move. When the sliding plate extends, the fixing rod abuts against the locking rod. At this time, if the support rod is collided and the support sliding rod is pushed to slide, the locking rod abutted by the fixing rod will abut against the support sliding rod, thereby reducing the possibility of the support rod continuing to slide and causing the screening equipment to shake, and improving the stability of the support of the screening equipment.

[0020] Preferably, the locking rod is provided with a first inclined surface, and the fixing rod is provided with a second inclined surface, and the first inclined surface can be in contact with the second inclined surface.

[0021] By adopting the above technical solution, the first inclined surface on the locking rod abuts against the second inclined surface on the fixing rod, so that when the support sliding rod slides, it abuts against and drives the locking rod to rotate and then slides to the other end of the locking rod. At this time, if the support sliding rod slides back to its original position in the reverse direction, the first inclined surface on the locking rod abuts against the second inclined surface of the fixing rod, thereby locking the reset of the support sliding rod and realizing the effect of the locking rod unidirectionally locking the support sliding rod. It is not necessary to lift the screening equipment first and then lift the outrigger, which is convenient for use.

[0022] Preferably, an auxiliary plate is arranged on the inner wall of the sliding groove. The auxiliary plate abuts against the sliding plate, and the locking rod is rotatably arranged on the auxiliary plate.

[0023] By adopting the above technical solution, the auxiliary plate abuts against the sliding plate for limiting, thereby improving the stability of the sliding of the sliding plate.

The screening equipment includes a plurality of vibration motors for vibration. The controller is connected to the gravity sensors and the vibration motors by signals, and the controller is used to adjust the parameters of the vibration motors according to the measured values of the gravity sensors.

[0025] By adopting the above technical solution, the quantity of the material is detected by the gravity sensors on the screening equipment, and then the parameters of the vibration motors are controlled according to the amount of the material entering the screening equipment, so as to control the vibration amplitude and frequency, and perform vibration screening better, making the screening equipment more efficiently used.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a machine body, a conveyor belt, a screening equipment, moving wheels, legs and a support driving member, the moving wheels can drive the machine body to move. When screening is required, after moving the machine body to the screening position, the support driving member is started, and the support driving member drives the legs to slide out and lift the machine body, so that the moving wheels are separated from the ground, thereby fixing the machine body. At this time, the conveyor belt and the screening equipment are started, the material is put on the conveyor belt, and the conveyor belt sends the material into the screening equipment for vibration screening. The operation is simple and convenient. Screening can be carried out without building a foundation and assembling the whole screening station, improving the convenience of use. After screening, the legs are retracted by the support driving member, so that the moving wheels contact the ground, and then the machine body can be moved, which is convenient for recycling and improves the applicability; 2. By providing a first connecting rod, a second connecting rod, a lifting driving member, a support rod, a support block, a support groove and a support sliding rod, the lifting driving member is started to push the screening equipment to rotate for lifting, and the conveyor belt is driven to lift by the assistance of the first connecting rod and the second connecting rod. During this process, the support rod rotates to support and the support sliding rod slides in the support groove of the support block, so as to support the end of the screening equipment far from the machine body by the support rod, thereby improving the stability of the screening equipment after lifting. The operation is simple and convenient. The inclined screening equipment is convenient for screening, improving the convenience of use; 3. By providing a sliding groove, a sliding plate and a sliding assembly, the sliding of the sliding plate in the sliding groove is adjusted by the sliding assembly.

The conveyor belt 3 and the screening machine 2 are arranged on the machine body 1. The conveyor belt 3 is driven to rotate by a motor. An outer shell is arranged outside the conveyor belt 3. The conveyor belt 3 is used to transport materials and input them into the feeding port at the top of the screening machine 2. The screening machine 2 is used for screening. The screening machine 2 is provided with a plurality of high-frequency vibration motors 21 to adjust the screening frequency of each sieve layer, effectively improving the screening efficiency and the grading accuracy of aggregates. The machine body 1 is rotatably provided with a plurality of moving wheels 16, and a driving motor is arranged inside the machine body 1 and cooperates with a transmission shaft to drive one group of moving wheels 16 to rotate, thereby driving the machine body 1 to move. A plurality of brackets 11 are fixedly arranged on the side wall of the machine body 1. A channel is opened on one side of the bracket 11 close to the machine body 1. A leg 111 that can extend out of the bracket 11 is slidably arranged in the channel of the bracket 11. A support hydraulic cylinder 112 is fixedly arranged on the side wall of the bracket 11 as a support driving member. A connecting plate is connected between the piston rod of the support hydraulic cylinder 112 and the bottom of the leg 111. The support hydraulic cylinder 112 is a multi-stage cylinder and can push the leg 111 to move different distances as needed, thereby lifting the machine body to different heights. By the cooperation of the moving wheels 16 and the lifting of the legs 111, this screening station can be moved away, eliminating the need to build a foundation and assemble equipment, improving the convenience of use.

[0034] For the convenience of movement, referring to Figure 1 and Figure 2 , a sliding groove 12 is arranged on the surface of the machine body 1. The sliding groove 12 communicates with the side wall at one end of the machine body 1. A sliding plate 4 is slidably arranged in the sliding groove 12 in a matching manner. An installation frame 24 is fixedly arranged on the outer wall of the screening machine 2. The bottom wall at one end of the installation frame 24 is rotatably hinged on the sliding plate 4. The sliding plate 4 and the machine body 1 are both provided with slot holes through which the discharge pipes of each stage of the screening machine 2 can pass and move and rotate. The machine body 1 is provided with a sliding assembly 5, and the sliding assembly 5 is used to drive the sliding plate 4 to slide. Driving the sliding plate 4 to slide through the sliding assembly 5 can reduce the overall length of the machine body 1, thereby facilitating movement and parking.

[0035] To improve the convenience of use, referring to Figure 1 and Figure 2, the sliding assembly 5 includes a first sliding gear 53, a second sliding gear 54, a first sliding rack 51 and a second sliding rack 52. The machine body 1 is provided with a limiting groove 123 and a first transmission groove 121. The limiting groove 123 links the first transmission groove 121 and the sliding groove 12. A second transmission groove 122 is provided on the side wall of the machine body 1. The first sliding rack 51 is slidably arranged in the second transmission groove 122 and is fixedly connected to the support leg 111 through a connecting plate. The first sliding gear 53 is rotatably arranged in the second transmission groove 122 and meshes with the first sliding rack 51.

The second sliding gear 54 is rotatably arranged in the first sliding groove 12 and is coaxially connected to the first sliding gear 53 through a rotating shaft. The second sliding rack 52 is inserted into the first transmission groove 121 and meshes with the second sliding gear 54. When the support leg 111 extends, it drives the first sliding rack 51 to move and drives the first sliding gear 53 to rotate, thereby driving the second sliding gear 54 to rotate. With the help of the second sliding rack 52, the sliding plate 4 is pushed to slide, which is simple and convenient to operate and convenient to use.

[0036] To improve the screening efficiency, referring to Figure 1 , at both ends of the outer shell of the conveyor belt 3, a first connecting rod 31 and a second connecting rod 32 are respectively rotatably hinged. One end of the first connecting rod 31 away from the conveyor belt 3 is rotatably hinged to one end of the machine body 1 away from the screening machine 2, and one end of the second connecting rod 32 away from the conveyor belt 3 is rotatably hinged to one end of the screening machine 2 away from the first connecting rod 31. A pair of lifting hydraulic cylinders 22 are rotatably arranged on the sliding plate 4 as lifting driving members, and the piston rods of the lifting hydraulic cylinders 22 are rotatably hinged to the side wall of the mounting frame 24. When the lifting hydraulic cylinders 22 are started, the screening machine 2 is driven to rotate and lift, so that the feeding port of the screening machine 2 is set at a high place, which is convenient to improve the screening efficiency by using the physical gravitational potential energy. At the same time, the conveyor belt 3 rises following the screening machine 2 with the assistance of the first connecting rod 31 and the second connecting rod 32.

[0037] To improve the screening stability, referring to Figure 1 and Figure 2 , a pair of support rods 41 are rotatably arranged on the bottom wall of the mounting frame 24. Along the length direction, a support block 42 is fixedly arranged on the surface of the sliding plate 4. A support groove 421 is provided through the side wall of the support block 42. One end of the support groove 421 away from the conveyor belt 3 is arc-shaped and is inclined upward. One end of the support rod 41 away from the screening machine 2 is fixedly provided with a support sliding rod 411, and the support sliding rod 411 is adaptively slidably arranged in the support groove 421. When the screening machine 2 rises, the support rod 41 rotates to drive the support sliding rod 411 to slide in the support groove 421, so that the support rod 41 extends out. The support rod 41 abuts against the screening machine 2, sharing the pressure borne by the lifting hydraulic cylinders 22, and at the same time reducing the possibility of sliding and shaking of the screening machine 2 during use, thereby improving the stability of the screening machine 2 during use.

[0038] To improve stability, refer to Figure 1 and Figure 3 , an auxiliary plate 15 is fixedly arranged on the top wall of the machine body 1. The auxiliary plate 15 abuts against the top wall of the sliding plate 4. A locking rod 151 is rotatably arranged on one side of the auxiliary plate 15 close to the support block 42 through a connecting block. The support sliding rod 411 can be attached to and push the locking rod 151 to rotate. A fixing rod 422 is fixedly arranged on one side of the support block 42 close to the locking rod 151. The bottom wall of the locking rod 151 is inclined with a first inclined surface 152, and the top wall of the fixing rod 422 is provided with a second inclined surface 423. The first inclined surface 152 can abut against the second inclined surface 423. After the sliding plate 4 extends out, the fixing rod 422 abuts against the locking rod 151 so that the first inclined surface 152 abuts against the second inclined surface 423. At this time, when the screening machine 2 is lifted, the support sliding rod 411 will abut against and push the locking rod 151 to rotate. The support sliding rod 411 moves to the other side of the locking rod 151 and slides a certain distance, so that the support rod 41 abuts against the screening machine 2, and at the same time, a space for the locking rod 151 to slide down is left. After the locking rod 151 slides down, it abuts against the fixing rod 422. At this time, if the support rod 41 is pushed by a collision to drive the support sliding rod 411 to slide, the locking rod 151 abutted by the fixing rod 422 will abut against the support sliding rod 411, thereby reducing the possibility of the support rod 41 continuing to slide and causing the screening equipment to shake, and improving the stability of the support of the screening equipment.

[0039] A mobile high-frequency screening station intelligent adjustment system, refer to Figure 1 and Figure 4 , includes a number of gravity sensors and a controller 6. The gravity sensors are arranged on each layer of the sieve mesh of the screening machine 2 to detect the gravity of the material on the sieve mesh. The controller 6 is a PLC arranged in the electric control cabinet 14 at one end of the machine body 1 and is signal-connected to the gravity sensors and the vibration motors 21. The controller 6 is used to adjust the parameters of the vibration motors 21 according to the measured values of the gravity sensors. The touch screen 141 on the electric control cabinet 14 can be used for manual operation to control the vibration motors 21. In another embodiment, the gravity sensors are also arranged on the conveyor belt 3 to measure the weight of the material in advance to facilitate the adjustment of the vibration mode. At the same time, a motor-controlled closed cover is arranged inside the feeding port of the screening machine 2 to seal the inside of the screening machine 2. The screening machine 2 is provided with a vacuum pump 23 with the same model as the controller 6, and the inside of the screening machine 2 can be cleaned by pumping vacuum through the vacuum pump 23. In another embodiment, a spraying device can be arranged inside the screening machine 2 to cooperate with the cleaning of the inside of the screening machine 2. The machine body 1 is provided with a hydraulic station 13 connected to the lifting hydraulic cylinder 22 and the support hydraulic cylinder 112 through pipelines (not shown in the figure) to supply hydraulic pressure. The hydraulic station 13 is signal-connected to the controller 6 for convenient operation. This intelligent adjustment system assists in the use of the screening machine 2, automatically adjusts the vibration amplitude and frequency according to the material weight, effectively improves the screening efficiency and the aggregate grading accuracy, and at the same time coordinates the control of dust removal, support and lifting, and adds a manual touch control function with the touch screen 141, facilitating the use of the entire screening station.

[0040] The implementation principle of a mobile high-frequency screening station in an embodiment of this application is as follows: By adding a mobile wheel 16 structure to the machine body 1 and cooperating with control driving devices such as motors or engines inside the machine body 1, a vehicle frame is formed. Through the support hydraulic cylinder 112 cooperating with the support leg 111, the overall machine body 1 can be lifted and fixed on the ground. At the same time, through the cooperation of the sliding assembly 5, the sliding plate 4 can be synchronously driven to extend. At this time, the lifting hydraulic cylinder 22 is started, and the screening machine 2 and the conveyor belt 3 are lifted with the cooperation of various rotating components. At the same time, the support rod 41 is propped up, and the locking rod 151 and the fixing rod 422 are cooperated to lock and limit the support rod 411, thereby performing insurance locking on the support rod 41. Through the above structure, the screening station is convenient to move and assemble. Compared with the fixed screening station, there is no need to make a foundation on-site and assemble the conveyor belt 3 and the screening machine 2, which improves the convenience of use.
