Description

Technical Field

[0001] The invention relates to the technical field of stone transportation, and in particular to stone transportation equipment with intelligent screening. Background Art

[0002] In the process of graded crushing of stones, each time the crushing device is replaced, it needs to be screened. The smaller-sized stones screened out will be put into the next-level crushing device, and the larger-sized stones will be returned to the upper device for re-crushing to extend the service life of the crushing devices at each level; the existing screening devices often use simple screens to intercept large-sized stones. Although the separated small-sized stones can be directly transported to the next-level crushing device by a conveyor belt assembly or a screw conveyor, the large-sized stones intercepted on the screen still need to be transported manually, so a stone conveying equipment with intelligent screening is needed. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a stone conveying equipment with intelligent screening, which has the advantages of accurate screening and suitable for bidirectional transportation.

[0004] To achieve the above purpose, the technical solution of the present invention is: a stone conveying equipment with intelligent screening, including a screening device and a guide frame. Among them, the screening device includes a screening plate in the shape of an inverted terrace, a rotating drive member, a panel, a first movable plate and an electromagnet control assembly; the screening plate is provided with a plurality of sieve holes, the driving shaft of the rotating drive member is connected to the rotation center of the screening plate, and the screening plate is driven to rotate so that stones of different masses are centrifuged on the surface of the screening plate, a convex portion is provided around the highest point of the screening plate, and a plurality of limit grooves are provided around the convex portion, one side of the first movable plate is embedded in the limit groove and is rotatably connected to the limit groove, a magnetic member is provided on the bottom of the first movable plate near one side of the screening plate, and a plurality of electromagnet control assemblies are arranged one by one below the plurality of limit grooves and corresponding to the position of the magnetic member, the panel is provided around the screening plate and connected to the convex portion, and a plurality of sensor switches corresponding to the electromagnet control assembly are provided around the panel, and the sensor switch is connected to the electromagnet control assembly. One end of the guide frame is arranged below the first movable plate. When the sensor switch detects the guide frame, the electromagnet control component is powered off. At this time, the first movable plate swings downward to allow the large-grained stone above it to roll out along the guide frame.

[0005] Furthermore, the device also includes a blocking component, which is mounted above the screening device. The blocking component includes a fixed ring and a second movable plate. The outer ring of the fixed ring is provided with a plurality of grooves, and the second movable plate is rotatably disposed in the grooves.

[0006] Furthermore, the equipment also includes a conveying assembly, which includes a translation conveyor belt and a lifting conveyor belt assembly. The translation conveyor belt is arranged below the screening device to transport the screened small-particle stone to one side; one end of the lifting conveyor belt assembly is arranged below the translation conveyor belt, and the other end of the lifting conveyor belt assembly is connected to an adjusting rod. The adjusting rod is started to operate to raise the other end of the lifting conveyor belt assembly.

[0007] Furthermore, the lifting conveyor belt assembly includes an active roller, a driven roller, a tensioning roller and a conveyor belt, the active roller is arranged below the translation conveyor belt, the driven roller is arranged on the end of the adjusting rod away from the active roller, the tensioning roller is arranged between the active roller and the driven roller, and the conveyor belt is arranged around the active roller, the tensioning roller and the driven roller. When the height of the driven roller changes, the position of the tensioning roller is moved to keep the conveyor belt in a taut state.

[0008] Furthermore, a slide track is provided on both the left and right sides of the active roller, a rack is provided in the slide track, and a gear meshing with the rack is provided on both the left and right sides of the tensioning roller, and the gear rotates to drive the tensioning roller to move along the slide track.

[0009] Furthermore, the two adjusting rods are respectively arranged at the left and right ends of the driven roller, the other end of the adjusting rod is rotationally connected to the sliding track and a driving motor is arranged at the connection between the two, and the driving motor drives the adjusting rod to swing.

[0010] Furthermore, the conveying assembly also includes a connecting plate, and the left and right sides of the connecting plate are rotatably connected to the two ends of the driven roller.

[0011] Furthermore, the outer ring of the conveyor belt is provided with a plurality of baffles.

[0012] Furthermore, the diameter of the sieve holes on the side wall of the sieve plate gradually increases from a low position to a high position.

[0013] Furthermore, the equipment also includes a bracket, a bearing and a bearing seat. The bracket mounts the screening device above the conveying assembly, the rotating drive member is disposed on the top of the bracket, the bearing seat is disposed on the bracket, and the enclosure is fixed in the bearing seat through the bearing.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

[0015] The present invention drives the self-rotation of a screening plate in the shape of an inverted terrace by providing a rotating driving member, so that stones of different masses are subjected to centrifugal motion on the surface of the screening plate. Because the greater the mass, the greater the centrifugal force, only stones of a certain mass can reach the convex part around the screening plate during rotation, and stones with a particle size smaller than the diameter of the screen hole pass through the screen hole and fall downward under the obstruction of the enclosure plate, thereby achieving stone screening; by providing a first movable plate, the first movable plate is controlled to swing by an electromagnet control component and a sensor switch, so that the separated large-particle stones can be automatically discharged along the guide frame, thereby achieving two-way transportation after screening, realizing the integration of screening and transportation, reducing manual intervention, and making screening more accurate.

[0016] The present invention intercepts and performs secondary screening on the stones reaching the convex portion by arranging a second movable plate located above the screening plate. Because there is a certain gap between the second movable plates, it can ensure that small particles reaching the top of the screening plate pass through, thereby achieving secondary screening. At the same time, because the second movable plate is rotatably connected to the fixed ring, it can ensure that large-particle stones can smoothly pass through the gap between the first and second movable plates when the first movable plate tilts downward.

[0017] The present invention arranges a conveying component so that a translation conveyor belt is arranged below a screening plate to collect small-particle stones, and then arranges an elevated conveyor belt component with adjustable height at one end to adjust the conveying point of the stone according to the target height, so that the entire device is more suitable for flow crushing.

[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0041] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but are not used to limit the present invention.

[0042] Reference Figure 1-6 The present invention provides a technical solution: a stone conveying device with intelligent screening. The device includes a screening device 1, a guide frame 2, a blocking component 3, a conveying component 4, a bracket 5, a bearing and a bearing seat 6.

[0043] The screening device 1 includes a screening plate 11 in the shape of an inverted terrace, a rotary drive member 12, a surrounding plate 13, a first movable plate 14 and an electromagnet control assembly 15. The screening plate 11 is provided with a plurality of screening holes 111, and the diameter of the screening holes 111 on the side wall of the screening plate 11 gradually increases from a low position to a high position. The rotary drive member 12 is fixed to the top of the bracket 5 and its driving shaft is connected to the rotation center of the screening plate 11, driving the screening plate 11 to rotate so that stones of different masses are subjected to centrifugal motion on the surface of the screening plate 11. A convex portion 16 is provided at the highest point of the screening plate 11, and a plurality of limiting grooves 161 are provided on the convex portion 16. One side of the first movable plate 14 is embedded in the limiting groove 161 and is rotationally connected to the limiting groove 161. A magnetic part is provided at the bottom of the first movable plate 14 near the side of the screening plate 11. The magnetic part is a material that can be attracted by a magnet. The connection method can be embedded or glued. At the same time, in order to ensure that the first movable plate 14 can swing after losing magnetic attraction, a counterweight block can be provided on the side of the movable plate away from the limit groove 161. Several electromagnet control components 15 are arranged one by one below the several limit grooves 161 and correspond to the positions of the magnetic part. The swing control of the first movable plate 14 is achieved by controlling the power supply of the electromagnet control components 15. The enclosure 13 is arranged around the screening plate 11 and connected to the protrusion 16. The enclosure 13 is used to change the movement trajectory of small particles of stone falling during the rotation process to ensure that they fall downward. If necessary, a buffer material layer can be provided on the inner circle of the tail plate. The outer ring of the enclosure 13 is provided with several sensor switches 131 corresponding to the electromagnet control components 15, and the sensor switches 131 are connected to the electromagnet control components 15.

[0044] The guide frame 2 is used to transport large-grained stones on the convex part 16 of the screening plate. The guide frame 2 can be composed of an inclined plate and a support. If necessary, a movable universal wheel can be set at the bottom of the support. The highest end of the guide frame 2 is set below the first movable plate 14. The sensor switch 131 cuts off the power of the electromagnet control component 15 when the guide frame 2 is detected. The sensor switch 131 can be a distance sensor, which cuts off the power when it detects that there are objects in the target range; a signal transmitter can also be set on the guide frame 2, and the sensor cuts off the power when it receives the signal from the signal transmitter. After the electromagnet control component 15 is powered off, it loses its magnetic force. The first movable plate 14 swings downward under the action of gravity and contacts one end of the guide frame 2, and the large-grained stones above it roll out along the guide frame 2.

[0045] The blocking assembly 3 is mounted above the screening device 1 to intercept the stones that move violently under the centrifugal action.

[0047] To ensure the function of raising one end of the conveyor belt, the lifting conveyor belt assembly 42 may include an active roller 421, a driven roller 422, a tensioning roller 423 and a conveyor belt 424. The active roller 421 is arranged below the translation conveyor belt 41, and the driven roller 422 is arranged at one end of the adjusting rod 43 away from the active roller 421. The adjusting rod 43 may be a rod with a telescopic function; or a rod with a fixed length. When the adjusting rod 43 is a rod with a fixed length, there are two adjusting rods 43, which are respectively arranged at the left and right ends of the driven roller 422. The other end of the adjusting rod 43 is rotatably connected to the sliding track 44 and a driving motor 45 is arranged at the connection between the two.
