Description

Technical Field

[0001] This disclosure relates to the field of material sorting, specifically to an upward-opening door assembly and a sorting machine. Background Technology

[0002] In material sorting machines used in applications such as ore sorting, X-rays are often emitted to identify the ore content. The top-hinged door of the sorting machine facilitates the maintenance of internal parts. A lead layer can be installed on the inside of the top-hinged door to prevent X-ray leakage. However, lead doors are often quite heavy, making them relatively difficult to open. Furthermore, once opened, they are not easily kept in a fixed position, and the door may accidentally close during maintenance, potentially causing an accident. Utility Model Content

[0003] To overcome the problems existing in related technologies, an exemplary embodiment of this disclosure provides a first aspect of a top-hinged door assembly applied to a sorting machine with an internal X-ray machine. The top-hinged door assembly includes: a support frame comprising a first crossbeam, a second crossbeam, and a third crossbeam parallel to each other, wherein the second crossbeam is located below the first crossbeam; a door panel with a lead layer disposed on its inner side, and the top edge of the door panel hinged to the first crossbeam; and a support assembly comprising: a first connecting rod, a second connecting rod, and a driving device; wherein the first connecting rod is hinged at one end to the inner side of the door panel for opening and closing the door panel; the second connecting rod is hinged at one end to the first connecting rod and at the other end to the second crossbeam; the driving device is disposed on the third crossbeam; the piston rod of the driving device is hinged to the side of the second connecting rod; the extension and retraction of the piston rod causes the second connecting rod to swing, the swinging of the second connecting rod causes the first connecting rod to swing, and the swinging of the first connecting rod causes the door panel to swing.

[0004] In some embodiments, the support assembly further includes a limiting device disposed at the connection between the second link and the first link, for assisting in keeping the second link and the first link in a straight line.

[0005] In some embodiments, the upward-opening door assembly further includes: a mounting base disposed on the inner side of the door panel for connecting the first connecting rod; the sum of the vertical length from the first crossbeam to the second crossbeam and the length of the first connecting rod is less than or equal to the sum of the length of the second connecting rod and the length from the mounting base to the first crossbeam.

[0006] In some embodiments, the upward-opening door assembly further includes: a first fixing seat, fixedly disposed on the third crossbeam, for hinged to one end of the cylinder body of the drive device; and a second fixing seat, fixedly disposed on the second crossbeam, for hinged to one end of the second connecting rod.

[0007] In some embodiments, the opening angle of the door panel is 0-100 degrees.

[0008] In some embodiments, the door panel is provided with a switching device for turning the power supply of the X-ray machine on and off.

[0009] In some embodiments, the switching device includes: a base plate fixedly mounted on the bracket; a micro switch vertically mounted on the door panel and coupled to the power supply of the X-ray machine, wherein the mechanical probe of the micro switch extends vertically downward and is capable of telescopic movement in the vertical direction; in the closed state of the door panel, the mechanical probe abuts against the base plate and retracts, and the micro switch turns on the power supply of the X-ray machine; in the open state of the door panel, the mechanical probe disengages from the base plate and extends, and the micro switch disconnects the power supply of the X-ray machine.

[0010] In some embodiments, the support component is provided with one or more.

[0011] In some embodiments, the upward-opening door assembly further includes a control device that controls the extension and retraction of the piston rod of the drive device in response to an operation command.

[0012] In a second aspect, this disclosure also provides a sorting machine for material sorting, comprising: a belt conveyor for conveying materials; an identification device for identifying the materials conveyed by the belt conveyor by an X-ray machine; and an upward-opening door assembly as described in the first aspect for opening and supporting the door panel.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0014] This disclosure provides an upward-opening door assembly and a sorting machine. The upward-opening door assembly, through the inclusion of a support component, uses a piston rod of a drive device to extend and retract, causing a second connecting rod to swing. This second connecting rod then swings a first connecting rod, which in turn swings the door panel. This allows the door panel, with a lead layer on its inner side, to be easily opened and closed, ensuring stability during opening and closing and facilitating maintenance. Furthermore, when the door panel is flipped to the appropriate position (maximum angle), the piston rod of the drive device stops extending. At this point, the first and second connecting rods are aligned, preventing the door panel from closing even with significant external force. The door panel is also supported by the first and second connecting rods, preventing accidental closure and ensuring operational safety. Attached Figure Description

[0023] A sorting machine is a device that separates crushed ore and gangue. It consists of a belt conveyor, an identification device, and a sorting device. The belt conveyor is used to transport materials; the identification device is a crucial component of the sorting machine, primarily emitting X-rays to identify the materials being transported by the belt conveyor. The sorting device separates the materials based on the identification results. Because X-rays are present inside the sorting machine, a 2-3mm thick layer of lead sheet is often bonded to the inner layer of the outer door to reduce radiation leakage. However, due to the high density of lead, the weight of the door doubles after the lead sheet is applied. For ease of maintenance, an upward-opening hinged door is designed for the side door of the sorting machine, which meets daily maintenance needs. However, because the upward-opening door is heavy and difficult to open, it requires external force. Furthermore, the door may accidentally close during maintenance, potentially causing an accident.

[0024] To overcome the problems existing in related technologies, an exemplary embodiment of this disclosure provides a top-hinged door assembly 100, which can be applied to a sorting machine containing an X-ray machine. The sorting machine can have multiple top-hinged doors, and correspondingly, multiple top-hinged door assemblies 100 can be provided. The control system can be configured and modified to open and close one or more top-hinged doors. For example... Figure 1 , Figure 2 , Figure 3 As shown, the upward-opening door assembly 100 may include: a bracket 110, a door panel 120, and a support assembly 130.

[0025] Bracket 110, such as Figure 1As shown, the structure may include a first crossbeam 111, a second crossbeam 112, and a third crossbeam 113 that are parallel to each other, wherein the second crossbeam 112 may be located below the first crossbeam 111. The bracket 110 may be made of high-strength materials such as steel or aluminum alloy, possessing strong load-bearing capacity and rigidity. The first crossbeam 111, second crossbeam 112, and third crossbeam 113 may be arranged parallel to each other. The first crossbeam 111 may be connected to the door panel 120 via hinges, facilitating the opening and closing of the door panel. Support components 130 may be connected to both the second crossbeam 112 and the third crossbeam 113, allowing the support components 130 to drive the door panel 120 to swing and support the door panel 120. The first crossbeam 111, second crossbeam 112, and third crossbeam 113 may be fixed using other rigid structures, such as brackets with a setting direction for grounding.

[0026] Door panel 120, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a lead layer can be provided on the inner side of the door panel 120, and the top edge of the door panel 120 can be hinged to the first crossbeam 111. The lead layer on the inner side of the door panel 120 can effectively prevent X-ray leakage. A reinforcing rib 121, which is elongated, can be provided on the inner side of the door panel 120 to reinforce it, effectively enhancing its rigidity, strength, and durability, and extending its service life. A mounting base 122 can be provided on the inner side of the door panel 120, which can be welded and can be connected to the support assembly 130. The top edge of the door panel 120 can be connected to the first crossbeam 111 via a hinge, with one end of the hinge fixedly connected to the first crossbeam 111 and the other end connected to the top edge of the door panel 120. The door panel 120 can be opened and closed with the support of the first crossbeam 111.

[0027] Support component 130, such as Figure 1 , Figure 2 , Figure 3 As shown, high-strength materials such as steel can be used to withstand large loads, and the assembly can include: a first connecting rod 131, a second connecting rod 132, and a drive device 133. The support assembly 130 can be installed inside the sorting machine door panel 120, which not only facilitates transportation but also does not affect the overall appearance of the equipment.

[0028] First link 131, as Figure 1 , Figure 2 , Figure 3 As shown, one end can be hinged to the inside of the door panel 120, and can be used to open and close the door panel. Both ends of the first connecting rod 131 can be provided with hinge holes, which can be hinged to the mounting base of the door panel 120.

[0029] Second link 132, as Figure 1 , Figure 2 , Figure 3 As shown, one end of the second connecting rod 132 can be hinged to the first connecting rod 131, and the other end can be hinged to the second crossbeam 112. The second connecting rod 132 can extend to form a side portion, and both ends and the side portion of the second connecting rod 132 can be provided with hinge holes. One end can be hinged to the first connecting rod 131, and the other end can be hinged to the second crossbeam 112. The hinged connection can be achieved by connecting the second connecting rod 132 to the second crossbeam 112 with a pin, and fixing the pin with a cotter pin. The cotter pin not only prevents the pin from falling off, but also facilitates disassembly and maintenance.

[0030] Drive unit 133, such as Figure 1 , Figure 2 , Figure 3 As shown, it can be installed on the third crossbeam 113; the piston rod of the drive device 133 can be hinged to the side of the second connecting rod 132; the piston rod can extend and retract to drive the second connecting rod 132 to swing, the swing of the second connecting rod 132 can drive the first connecting rod 131 to swing, and the swing of the first connecting rod 131 can drive the door panel 120 to swing. The drive device 133 can be a pneumatically driven cylinder or an electricly driven cylinder. One end of the piston rod of the drive device 133 can be hinged to the side of the second connecting rod 132. When the door panel needs to be opened, the piston rod of the drive device 133 extends, driving the second connecting rod 132 to swing, which in turn drives the first connecting rod 131 to swing, and the door panel 120 opens under the action of the first connecting rod 131. When the door panel 120 is opened to the appropriate position, the piston rod of the drive device 133 stops extending and retracting, and extends stably to a certain position, supporting the door panel 120 to a fixed position through the first link 131 and the second link 132; when the door panel 120 needs to be closed, the piston rod of the drive device 133 retracts, which can drive the second link 132 and the first link 131 to close the door panel 120 until it is completely closed.

[0031] In this embodiment, an upward-opening door assembly 100 is provided. The piston rod of the drive device 133 extends and retracts, causing the second connecting rod 132 to swing. The swinging of the second connecting rod 132 causes the first connecting rod 131 to swing, which in turn causes the door panel 120 to swing, making the lead-layered door panel 120 easy to open and close. Furthermore, when the door panel 120 is opened to a suitable position (maximum angle), the piston rod of the drive device 133 no longer extends. The door panel 120 can be supported in the suitable position, i.e., the maximum angle position, by the support assembly 130. At this time, the first connecting rod 131 and the second connecting rod 132 are in a straight line. Even if a large external force is applied to the door panel 120, the door panel 120 cannot be closed. The support of the door panel 120 by the first connecting rod 131 and the second connecting rod 132 prevents accidental closure of the door panel 120 and avoids danger to personnel, ensuring the safety of maintenance personnel.

[0032] In some embodiments, the support assembly 130 may further include a limiting device, which may be disposed at the connection between the second link 132 and the first link 131, and may be used to help keep the second link 132 and the first link 131 in a straight line. When the piston rod of the drive device 133 is in the extended state and the second link 132 and the first link 131 are in a straight line, the piston rod of the drive device 133 stops moving, the door panel 120 is in the open state and can be fully supported by the support assembly 130. The limiting device may be disposed at the connection between the second link 132 and the first link 131 at this time, so that the maximum opening angle between the second link 132 and the first link 131 does not exceed 180 degrees, and may be used to limit the position of the door panel 120. The limiting device may be a bolt, a clamp, etc., and may be used to fix the second link 132 and the first link 131 together. In this embodiment of the present disclosure, by setting a limiting device, the second link 132 and the first link 131 can be kept in the same straight line state when the driving device continues to maintain the thrust. Fixing the connection between the second link 132 and the first link 131 can more stably support the door panel 120 and prevent the door panel 120 from closing accidentally.

[0033] In some embodiments, the upward-opening door assembly 100 may further include: a mounting base 122, such as Figure 1 , Figure 2 , Figure 3As shown, it can be located inside the door panel 120 and can be used to connect the first connecting rod 131. The sum of the vertical length of the first crossbeam 111 to the second crossbeam 112 and the length of the first connecting rod 131 can be less than or equal to the sum of the length of the second connecting rod 132 and the length from the mounting base to the first crossbeam 111. A mounting base 122 can be provided inside the door panel 120. A pin can be installed between the hinge hole of the first connecting rod 131 and the mounting base. A cotter pin is used to lock the pin to prevent it from falling off. The first connecting rod 131 can be hinged to the mounting base. If the vertical length of the first crossbeam 111 to the second crossbeam 112 is L1, the length of the first connecting rod 131 is L2, the length of the second connecting rod 132 is L3, and the length from the mounting base to the first crossbeam 111 is L4, L1, L2, L3, and L4 can form a double rocker structure in a four-bar linkage. The sum of the distance from the hinge hole on the first crossbeam 111 to the hinge hole of the second fixed seat on the second crossbeam 112 and the length of the first connecting rod 131 is less than or equal to the sum of the length of the second connecting rod 132 and the length from the mounting seat 122 of the door panel 120 to the hinge hole on the first crossbeam 112, and the first connecting rod 131 is the shortest rod. At this time, the distance from the hinge hole on the first crossbeam 111 to the hinge hole of the second fixed seat on the second crossbeam 112 is the bracket 110. Here, the first condition for the establishment of the double rocker mechanism is used: the sum of the length of the longest rod and the length of the shortest rod is less than or equal to the sum of the lengths of the other two rods, and the connecting rod (the opposite rod of the frame) is the shortest rod. If the sum of the distance from the hinge hole on the first crossbeam 111 to the hinge hole on the second fixed seat of the second crossbeam 112 and the length of the first connecting rod 131 is too large, and the sum of the length of the second connecting rod 132 and the length from the mounting seat 122 of the door panel 120 to the hinge hole on the first crossbeam 112 is too small, the double rocker structure may experience a local dead zone, making it unable to complete effective movement. This would cause the door panel 120 to be unable to open and close effectively, and it may also lose stability in certain situations, resulting in uncontrollable movement, making the opening and closing of the door panel 120 uncontrollable as well. In this embodiment, by ensuring that the sum of the distance from the hinge hole on the first crossbeam 111 to the hinge hole on the second fixed seat of the second crossbeam 112 and the length of the first connecting rod 131 is less than or equal to the sum of the length of the second connecting rod 132 and the length from the mounting seat 122 of the door panel 120 to the hinge hole on the first crossbeam 112, the reverse movement or discontinuous movement of the dual rocker structure can be avoided, thus ensuring the smoothness and controllability of the movement of the dual rocker structure, making the opening and closing of the door panel 120 more controllable and stable.

[0034] In some embodiments, the upward-opening door assembly 100 may further include: a first fixing seat 140, such as Figure 1 , Figure 2 , Figure 3As shown, a first fixed seat 140 can be fixedly mounted on the third crossbeam 113 and can be hinged to one end of the cylinder body of the drive device 133; a second fixed seat 140 can be fixedly mounted on the second crossbeam 112 and can be hinged to one end of the second connecting rod 132. The first fixed seat 140 can be fixed to the third crossbeam 113 by welding, bolting, or other means, and can be connected to the drive device 133. One end of the cylinder body of the drive device 133 can be hinged to the first fixed seat 140 by a pin. The pin can be fixed to the first fixed seat 140 and the cylinder body through a hole, which can ensure that the first fixed seat 140 is rotatably connected to the cylinder body. The cotter pin is installed in the hole of the pin and is pressed or locked to ensure that the hinge position of the cylinder body and the first fixed seat 140 does not loosen or shift. The second fixed seat can be fixed to the second crossbeam 112 by welding, bolting, or other means, and can be hinged to the second connecting rod 132. The hinge can be achieved by connecting the second connecting rod 132 to the second fixed seat of the second crossbeam 112 with a pin and fixing the pin with a cotter pin. The cotter pin not only prevents the pin from falling off, but also facilitates disassembly and maintenance. In this embodiment, by setting the first fixed seat 140 and the second fixed seat on the third crossbeam 113 and the second crossbeam 112, the pin can provide a rotatable connection, and the cotter pin can ensure the firmness and safety of the hinge position. This allows the cylinder body of the drive device 133 to be hinged to the first fixed seat 140 through the pin and the cotter pin, and the second connecting rod 132 to be hinged to the second fixed seat through the pin and the cotter pin.

[0035] In some embodiments, the opening angle of the door panel 120 can be 0-100 degrees. The maximum opening angle of the door panel 120 is 100 degrees. When the door panel 120 is opened to the maximum angle, the first link 131 and the second link 132 are in a straight line, and the piston rod of the drive device 133 extends and is fixed. At this time, the door panel 120 cannot be closed unless disturbed by external forces. The door panel 120 can be suspended between 0-100 degrees. However, once it is subjected to external force, the door panel 120 will close. If it is necessary to change the maximum opening angle of the door panel 120, it can be achieved by changing the length of the first link 131 and the second link 132. Therefore, the door panel 120 only has two states: closed and opened to the maximum angle of 100 degrees (during maintenance). This ensures that the door panel 120 will not collide with surrounding structures (such as walls, other equipment, etc.) when it is opened. If the opening angle of the door panel 120 exceeds the design stroke of the cylinder or motor system (e.g., exceeding 100 degrees), the drive unit 133 may not be able to provide sufficient force to overcome the load of the door panel 120, causing the door panel 120 to fail to open or close properly. In cases where the door panel 120 has a lead layer, the required pushing force may increase significantly under heavier conditions. In this embodiment, by limiting the opening angle of the door panel 120 to 0-100 degrees, the door panel 120 opens to 100 degrees when it needs to open and closes completely when it needs to close. This avoids overloading the drive unit 133, ensures that the cylinder or motor can operate stably within a reasonable design range, and improves the reliability and service life of the support assembly 130 while ensuring the door panel 120 can open normally.

[0036] In some embodiments, the door panel 120 may be equipped with a switching device for switching the power supply of the X-ray machine on and off. The switching device on the door panel 120 may be a microswitch. A mechanical microswitch can directly control the power supply of the X-ray machine. When the door panel 120 is closed, the door panel 120 pushes against the mechanical probe of the microswitch, turning on the X-ray machine. When the door panel 120 is open, the mechanical probe of the microswitch extends, turning off the power supply of the X-ray machine. In this embodiment, by providing a switching device on the door panel 120, the power supply of the X-ray machine can be effectively switched on and off when the door panel 120 is opened and closed. This avoids radiation problems caused by accidental opening of the lead door during the operation of the sorting machine, or accidental injury to operators from operating equipment.

[0037] In some embodiments, the switching device may include: a base plate and a micro switch.

[0038] The base plate can be fixedly mounted on the lower support of the sorting machine. The base plate can be made of a material with high strength and hardness, such as sheet metal. The top surface of the base plate can extend horizontally, and one end of the top surface can be fixedly mounted on the lower support of the sorting machine. The fixing method can be bolt connection, etc. The top surface can be positioned close to the door panel 120 of the sorting machine.

[0039] A microswitch, vertically mounted on the door panel 120 of the sorting machine, can be coupled to the power supply of the X-ray machine. The mechanical probe of the microswitch can extend vertically downwards and retract vertically. When the door panel 120 is closed, the mechanical probe abuts against the top surface and retracts, allowing the microswitch to power the X-ray machine. When the door panel 120 is open, the mechanical probe detaches from the top surface and extends, allowing the microswitch to disconnect the power supply. The microswitch can be vertically mounted on the door panel 120, near the lower support of the sorting machine, allowing the mechanical probe to extend vertically to abut the top surface of the base plate. The microswitch can be fixedly mounted on the door panel 120, using methods such as bolt connection. The microswitch can be coupled to the X-ray power supply. This coupling can be a direct electrical connection or a connection to a control device. The control device can then control the on / off state of the X-ray machine based on the microswitch's on / off state. When the mechanical probe of the microswitch retracts upwards, the X-ray power supply is turned on; when the mechanical probe extends downwards, the X-ray power supply is turned off. When the sorting machine's door 120 is closed, the mechanical probe of the microswitch can abut against the top surface of the base plate and is in the retracted state. In this case, the microswitch can directly turn on the X-ray machine's power supply, or it can turn on the X-ray machine's power supply by connecting the control device. When the sorting machine's door 120 is open, the mechanical probe of the microswitch can detach from the top surface of the base plate and is in the extended state. In this case, the microswitch can directly turn off the X-ray machine's power supply, or it can turn off the X-ray machine's power supply by disconnecting the control device.

[0040] In this embodiment, a switching device is provided. By vertically arranging the microswitch, the mechanical probe of the microswitch can extend and retract vertically, allowing it to contact and disengage from the horizontally arranged top surface of the base plate. When the sorting machine door 120 is closed, the horizontally arranged top surface of the base plate can contact the mechanical probe, ensuring that the mechanical probe remains retracted even when the sorting machine vibrates, thus guaranteeing that the microswitch can power on the X-ray machine. When the sorting machine door 120 is open, the mechanical probe can detach from the support plate, and the microswitch can disconnect the power supply to the X-ray machine.

[0041] In some embodiments, one or more support components 130 may be provided. One support component 130 can reduce costs, and multiple support components 130 can be arranged side by side on the door panel 120 to distribute the weight of the door panel 120 and enhance the overall stability and load-bearing capacity of the flip-up door assembly 100. In this embodiment of the present disclosure, the number of support components 130 can be set to ensure the stability of the opening and closing of the door panel 120.

[0042] In some embodiments, the upward-opening door assembly 100 may further include: a control device 150, such as... Figure 5 As shown, the control device 150 can respond to operation commands and control the extension and retraction of the piston rod of the drive device 133. The control device 150 may include an operation module 151 and an execution module 152. The operation module 151 can be connected to the execution module 152. The operation module 151 can generate user operation commands, which can come from a user interface (such as buttons, switches, touchscreens, etc.) or an external control system. The execution module 152 can control the extension and retraction of the piston rod of the drive device 133 based on the user's operation commands, thereby controlling the opening and closing of the door panel 120. In this embodiment, by setting the control device 150, the extension and retraction of the piston rod of the drive device 133 can be controlled based on operation commands, further improving the accuracy and stability of the piston rod's extension and retraction movement, thereby precisely controlling the opening and closing of the door panel 120.

[0043] Based on the same inventive concept, an exemplary embodiment of this disclosure also provides a sorting machine for material sorting, including: a belt conveyor, an identification device, such as the flip-up door assembly 100 in any of the foregoing embodiments, and a sorting device.

[0044] Belt conveyors are used to transport materials. A belt conveyor can be a conveyor belt, etc. Materials can be placed on the belt conveyor and transported to an identification device.

[0045] The identification device can identify materials conveyed by belt conveyors using an X-ray machine.

[0046] The upward-opening door assembly 100 can be used to open and support the door panel 120.

[0047] A sorting device is used to sort materials based on the identification results of an identification device. The sorting device can be installed downstream of a belt conveyor and can separate materials according to their category, thus separating different types of materials.

[0048] The sorting machine of this embodiment can transport materials via a belt conveyor, facilitating identification and classification by the identification device. Based on the identification device, the materials transported by the belt conveyor can be identified and classified using an X-ray machine. Finally, different types of materials are sorted by the sorting device, enabling accurate and rapid classification and sorting of the materials to be tested, with high identification and sorting accuracy. The flip-up door assembly 100 can be configured with a support assembly 130. The piston rod of the drive device 133 extends and retracts, causing the second connecting rod 132 to swing. The swinging of the second connecting rod 132 causes the first connecting rod 131 to swing, which in turn causes the door panel 120 to swing. This allows the door panel 120, which has a lead layer on its inner side, to be easily opened and closed, ensuring the stability of the door panel 120's opening and closing and facilitating maintenance. Furthermore, when the door panel 120 is flipped to the appropriate position, the piston rod of the drive device 133 stops extending, and the door panel 120 can be supported in the appropriate position by the first connecting rod 131 and the second connecting rod 132, preventing the door panel 120 from closing accidentally and ensuring operational safety.
