Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a mobile combined screening vehicle for detecting ore particle size. Background Technology

[0002] The mobile combined screening vehicle for ore particle size detection is a highly efficient and intelligent screening device specifically designed for mining sites. It integrates mobile deployment, precise screening, and data acquisition functions. The equipment uses a tracked chassis, allowing for rapid relocation to complex terrains such as mines and quarries. It can be put into operation without fixed infrastructure, significantly improving production flexibility. Its combined screening system achieves ore particle size classification and detection through a multi-layered screen structure, simultaneously producing qualified products of multiple particle sizes to meet the needs of different industrial scenarios. A built-in automated data processing module records and analyzes screening data in real time, accurately calculating the yield of each particle size, providing a scientific basis for production control. The equipment is equipped with a sealed screen box and dust removal system, effectively suppressing dust pollution. It also features a low-noise design, meeting environmental protection requirements. Furthermore, the equipment supports remote monitoring and intelligent parameter adjustment, is easy to operate, has low maintenance costs, and is suitable for high-intensity continuous operation. It is an important piece of equipment for modern mines to achieve efficient, environmentally friendly, and intelligent production.

[0003] In practical use, existing fixed screening machines typically use a single-layer screen plate design, which can only complete the classification of a single particle size. If multi-stage screening is required, the material needs to be transferred or the screen needs to be replaced multiple times, resulting in a longer operation cycle, frequent manual intervention, and unstable screening accuracy. In addition, in open-air operation environments, the screen plate is prone to clogging due to ore impact or the adhesion of wet materials, which further reduces screening efficiency. Therefore, a mobile combined screening vehicle for detecting ore particle size is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, where traditional fixed screening machines typically employ a single-layer screen plate design, which can only complete the grading of a single particle size. If multi-stage screening is required, materials need to be transferred or screens replaced multiple times, resulting in extended operating cycles, frequent manual intervention, and unstable screening accuracy. Furthermore, in open-air operating environments, the screen plates are prone to clogging due to ore impact or the adhesion of damp materials, further reducing screening efficiency. Therefore, this invention proposes a mobile combined screening vehicle for detecting ore particle size.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mobile combined screening vehicle for detecting ore particle size includes a device base plate, a movable wheel rotatably connected to the upper part of the device base plate, a rotating shaft fixedly connected to the movable wheel, a second transmission wheel fixedly connected to the upper part of the rotating shaft, a transmission belt drivingly connected to the upper part of the second transmission wheel, a first transmission wheel drivingly connected to the transmission belt, a first eccentric shaft fixedly connected to the first transmission wheel, a connecting rod rotatably connected to the first eccentric shaft, and a multi-stage screen plate rotatably connected to the connecting rod.

[0006] During the movement of the device, the moving wheels rotate, which in turn drives the second transmission wheel to rotate. The rotation of the second transmission wheel drives the first eccentric shaft to rotate, which in turn drives the multi-stage screen plate to move back and forth. This automatically screens the ore placed inside the multi-stage screen plate, ensuring the fineness of the screening while preventing the screen holes from being blocked due to ore impact or the adhesion of damp materials. The upper part of the multi-stage screen plate is divided into three areas, each with screen holes at the top. The three sections of the upper part of the screen plate are respectively equipped with screen holes of different specifications of coarse, medium and fine, thereby realizing multi-stage screening of the ore.

[0007] The above technical solution further includes: The device has a screening shell fixedly connected to the upper part of its base plate. Inside the screening shell, there are rotatable auxiliary wheels. The upper part of the auxiliary wheels is connected to a multi-stage screen plate. There are four auxiliary wheels.

[0008] The screening housing is equipped with a collection trough located directly below the multi-stage sieve plate. There are three collection troughs, which are respectively located at the bottom of the partitioned sieve holes.

[0009] A push handle is fixedly connected to the upper part of the base plate of the device, and the device is moved by pushing the handle.

[0010] A vibration mechanism is fixedly connected inside the screening housing, which drives the coarse screen plate to vibrate up and down.

[0011] The vibration mechanism includes a vibration housing fixedly connected to the upper part of the screening housing, a servo motor is installed inside the vibration housing, and a vibration component is installed at the output end of the servo motor.

[0012] The vibration assembly includes a second eccentric shaft located at the output end of a servo motor. The second eccentric shaft is rotatably connected to a connecting plate, and the connecting plate is rotatably connected to a vibration rod. The vibration rod is slidably connected to the vibration housing.

[0013] A pad is fixedly connected to the upper part of the vibrating rod, and a coarse screen plate is fixedly connected to the upper part of the pad. The pad can effectively reduce the impact of the vibration of the vibrating rod on the coarse screen plate. The screen holes on the upper part of the coarse screen plate have a large aperture, which can be used for coarse screening of minerals.

[0014] This utility model has the following beneficial effects: In this invention, the moving wheel rotates during the movement of the device, which in turn drives the second transmission wheel to rotate. The rotation of the second transmission wheel drives the first eccentric shaft to rotate, which in turn drives the multi-stage screen plate to reciprocate, thereby automatically screening the ore during the movement. The upper three sections of the multi-stage screen plate are sequentially equipped with coarse, medium, and fine screen holes of different specifications. Combined with the reciprocating movement driven by the moving wheel, the material forms a throwing-rolling composite motion on the multi-stage screen plate, effectively preventing screen hole clogging and improving the stratification efficiency.

[0015] In this invention, a coarse screen plate is also provided on the upper part of the multi-stage screen plate. The minerals are first coarsely screened on the upper part of the coarse screen plate. During the screening process, the coarse screen plate can be driven to vibrate up and down by activating the vibration mechanism. The vibration of the coarse screen plate can effectively improve the screening effect of the coarse screen plate and at the same time avoid the minerals from clogging the screen holes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1, as Figures 1-5As shown, the present invention proposes a mobile combined screening vehicle for detecting ore particle size, comprising a device base plate 1, a movable wheel 3 rotatably connected to the upper part of the device base plate 1, a rotating shaft 11 fixedly connected to the movable wheel 3, a second transmission wheel 12 fixedly connected to the upper part of the rotating shaft 11, a transmission belt 4 drivingly connected to the upper part of the second transmission wheel 12, a first transmission wheel 5 drivingly connected to the transmission belt 4, a first eccentric shaft 13 fixedly connected to the first transmission wheel 5, a connecting rod 14 rotatably connected to the first eccentric shaft 13, and a multi-stage screen plate 8 rotatably connected to the connecting rod 14.

[0020] During the movement of the device, the moving wheel 3 rotates, which in turn drives the second transmission wheel 12 to rotate. The second transmission wheel 12 then drives the first eccentric shaft 13 to rotate, which in turn drives the multi-stage screen plate 8 to reciprocate. This automatically screens the ore placed inside the multi-stage screen plate 8, ensuring screening precision while preventing screen blockage caused by ore impact or damp material adhesion. The upper part of the multi-stage screen plate 8 is divided into three areas, each with screen holes at its upper part. The three sections on the upper part of the screen plate are arranged according to... The device is equipped with coarse, medium and fine screens to achieve multi-stage screening of ore. The bottom plate 1 of the device is fixedly connected to the upper part of the screening shell 2. The screening shell 2 is rotatably connected to the auxiliary wheel 15.

The bottom plate 1 of the device is fixedly connected to the upper part of the device. The device is moved by the push handle 6.

[0021] In this embodiment, pushing the push handle 6 can drive the movable wheel 3 to rotate, thereby moving the device. During the movement of the device, the rotation of the movable wheel 3 can drive the fixedly connected rotating shaft 11 to rotate. The rotation of the rotating shaft 11 can drive the fixedly connected second transmission wheel 12 to rotate. The rotation of the second transmission wheel 12 can drive the first transmission wheel 5, which is connected by the transmission belt 4, to rotate. The rotation of the first transmission wheel 5 can drive the fixedly connected first eccentric shaft 13 to rotate.

The ore is automatically screened during the movement by the reciprocating motion of the multi-stage screen plate 8. The upper three sections of the multi-stage screen plate 8 are set with screen holes of different specifications of coarse, medium and fine in sequence. With the reciprocating movement driven by the moving wheel 3, the material forms a composite motion of throwing and rolling on the multi-stage screen plate 8, which effectively avoids screen hole clogging and improves the stratification efficiency. At the same time, the mobile chassis design allows the equipment to directly reach the mining site or transfer point, reducing the secondary handling of materials. The built-in grading and collection system can automatically guide the ore of different particle sizes to the corresponding collection tank 7, significantly reducing the intensity of manual sorting.

[0022] Example 2, as Figures 1-5 As shown, a vibration mechanism is fixedly connected inside the screening housing 2. The vibration mechanism drives the coarse screen plate 9 to vibrate up and down. The vibration mechanism includes a vibration housing 10 fixedly connected to the upper part of the screening housing 2. A servo motor 18 is installed inside the vibration housing 10. A vibration component is installed at the output end of the servo motor 18. The vibration component includes a second eccentric shaft 19 installed at the output end of the servo motor 18. A connecting plate 20 is rotatably connected to the second eccentric shaft 19. A vibration rod 16 is rotatably connected to the connecting plate 20. The vibration rod 16 is slidably connected to the vibration housing 10. A pad 17 is fixedly connected to the upper part of the vibration rod 16. The coarse screen plate 9 is fixedly connected to the upper part of the pad 17. The pad 17 can effectively reduce the impact of the vibration of the vibration rod 16 on the coarse screen plate 9. The screen holes on the upper part of the coarse screen plate 9 have a large aperture, which can be used for coarse screening of minerals.

[0023] In this embodiment, a coarse screen plate 9 is also provided on the upper part of the multi-stage screen plate 8. The minerals are first coarsely screened on the upper part of the coarse screen plate 9. During the screening process, the servo motor 18 can be started to drive the second eccentric shaft 19 to rotate. The rotation of the second eccentric shaft 19 can drive the rotating connecting plate 20 to rotate. The rotation of the connecting plate 20 can drive the rotating vibrating rod 16 to move back and forth. The reciprocating movement of the vibrating rod 16 can drive the coarse screen plate 9 to vibrate up and down. The vibration of the coarse screen plate 9 can effectively improve the screening effect of the coarse screen plate 9 and avoid the minerals from clogging the screen holes. During the vibration of the coarse screen plate 9, the pad plate 17 can prevent the vibration of the vibrating rod 16 from damaging the coarse screen plate 9.
