DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0039] Please refer to Figures 1 to 10. The trough type ore washer for laterite nickel ore includes a frame 1, a rotating shaft 2, a blade 3, a locking member 4 and a power device 6. The frame 1 is provided with a cleaning trough 11; the rotating shaft 2 is rotatably installed in the cleaning trough 11, and the rotating shaft 2 is provided with a cavity 23 and a slot 221 connected to the cavity 23; one end of the blade 3 is provided with a locking hole 321, and the blade 3 is adapted to the slot 221, and the end of the blade 3 having the locking hole 321 is inserted into the slot 221; the locking member 4 is movably installed in the cavity 23 along the direction of approaching and moving away from the blade 3, so that when approaching the blade 3, the locking member 4 is passed through the locking hole 321 to limit the blade 3 from detaching from the slot 221; the power device 6 is connected to the rotating shaft 2 for driving the rotating shaft 2 to rotate.

[0040] The trough type ore washer for laterite nickel ore provided by the present invention comprises the following: the frame 1 is provided with a cleaning trough 11; the rotating shaft 2 is rotatably installed in the cleaning trough 11; the rotating shaft 2 is provided with a cavity 23 and a slot 221 communicating with the cavity 23; one end of the blade 3 is provided with a locking hole 321; the blade 3 is adapted to the slot 221; the end of the blade 3 having the locking hole 321 is inserted into the slot 221; the locking member 4 is movably installed in the cavity 23 in the direction of approaching and moving away from the blade 3, so that when approaching the blade 3, the locking member 4 is passed through the locking hole 321 to limit the blade 3 from disengaging from the slot 221; the power device 6 is connected to the rotating shaft 2 for driving the rotating shaft 2 to rotate; when the blade 3 needs to be replaced, the locking member 4 is driven to move in the direction away from the blade 3 so that the locking member 4 is locked. The stopper 4 exits the locking hole 321, so that the blade 3 can be pulled out of the slot 221, and then the new blade 3 is inserted into the slot 221, and then the locking member 4 is driven to move toward the direction of the blade 3, so that the locking member 4 extends into the locking hole 321. Since the slot 221 is adapted to the blade 3, the locking member 4 is adapted to the locking hole 321, and the slot 221 can limit the circumferential movement of the blade 3, and the locking member 4 cooperates with the locking hole 321 to limit the radial movement of the blade 3. The blade 3 can be completely limited by the slot 221 and the locking member 4, thereby achieving the purpose of fixing the blade 3. The disassembly and installation can be completed by driving the locking member 4, the replacement speed is fast and the operation is simple, which greatly saves the equipment repair time and effectively improves the production efficiency.

[0041] At the same time, the cavity 23 is a sealed cavity, and the locking member 4 is located in the cavity 23, and the blade 3 is tightly matched with the slot 221. When the blade 3 is inserted into the slot 221, the slot 221 can be blocked, thereby preventing the sewage in the cleaning tank 11 from flowing into the cavity 23 from the slot 221, thereby preventing the locking member 4 from rusting and extending the service life of each component.

[0042] Specifically, please refer to Figure 1. The cleaning tank 11 is a tank body with the notch facing upward and the bottom in an arc shape. The cleaning tank 11 extends along a first direction. The rotating shaft 2 is adapted to the length of the cleaning tank 11. The rotating shaft 2 extends along the first direction. The two ends of the rotating shaft 2 are rotatably installed along the axial direction on the opposite side walls of the cleaning tank 11. The power device 6 is provided on the frame 1 and is located outside the cleaning tank 11. The power device 6 is connected to one end of the rotating shaft 2 for driving the rotating shaft 2 to rotate.

[0043] Further, referring to FIG1 , the power device 6 includes a driving motor and a reducer, the driving motor is connected to the reducer, and the reducer is connected to the rotating shaft 2 so as to drive the rotating shaft 2 to rotate through the driving motor.

[0044] Further, referring to Figures 2 to 4, there are multiple blades 3, and the multiple blades 3 are arranged at intervals along the length direction of the rotating shaft 2. The multiple blades 3 constitute a stirring group, and there are multiple stirring groups, and the multiple stirring groups are arranged at intervals along the circumference of the rotating shaft 2. Accordingly, the number of the slots 221 and the locking members 4 is consistent with the number of the blades 3. Specifically, in this embodiment, there are four stirring groups, and the four stirring groups are evenly arranged along the circumference of the rotating shaft 2, that is, the blades 3 on the entire rotating shaft 2 are arranged in an array along the circumference and radial direction of the rotating shaft 2. Accordingly, the slots 221 and the locking members 4 correspond to the number of the blades 3. Each blade 3 is inserted into the corresponding slot 221 and cooperates with the corresponding locking member 4.

[0045] Further, referring to Figures 3 and 10, the blade 3 includes a stirring section 31 and a connecting section 32 connected in sequence, and the cross-sectional area of ​​the stirring section 31 is larger than the cross-sectional area of ​​the connecting section 32, so that a step is formed at the connection between the stirring section 31 and the connecting section 32, and the step is arranged in a full circle, that is, the connecting section 32 is located in the middle of the end face of one end of the stirring section 31, and the step has an abutting side arranged toward the rotating shaft 2, and the abutting side is arranged in an arc shape and adapted to the outer periphery of the rotating shaft 2, and the locking hole 321 is located on the connecting section 32. When in use, the connecting section 32 extends entirely from the slot 221 into the cavity 23, and the abutting side abuts against the side of the rotating shaft 2. The stirring section 31 is located on the outer periphery of the rotating shaft 2, and the blade 3 can be limited by setting the step.

[0046] Furthermore, in order to improve the stirring efficiency, in this embodiment, the slots 221 are arranged at an angle, so that the blades 3 are arranged at an angle.

[0047] Furthermore, the movable direction of the locking member 4 is not restricted. In this embodiment, the locking hole 321 is extended along the first direction, that is, it is consistent with the radial direction of the rotating shaft 2. Accordingly, the locking member 4 is movably arranged in the cavity 23 along the first direction and is located on one side of the slot 221.

[0048] Furthermore, since there are a large number of blades 3 on the rotating shaft 2, each blade 3 is provided with a locking member 4. Therefore, when replacing a blade 3, each locking member 4 needs to be driven to move separately, which prolongs the replacement time. In this embodiment, referring to Figures 5 to 8, the trough-type ore washer for laterite nickel ore further includes a linkage member 51, which is slidably installed in the cavity 23 along the length direction of the rotating shaft 2. The linkage member 51 is connected to the multiple locking members 4 corresponding to the blades 3 in the stirring group, and the linkage member 51 is used to drive the multiple locking members 4 to move synchronously. That is, the linkage member 51 is connected to the multiple locking members 4 arranged in a straight line, so that the multiple locking members 4 can be driven to move simultaneously by the linkage member 51, thereby improving the replacement efficiency.

[0049] Please refer to Figures 5 to 8. In this embodiment, there are four stirring groups. Correspondingly, there are four linkage members 51. The four linkage members 51 correspond one-to-one to the four stirring groups. Each linkage member 51 is connected to the corresponding locking member 4 in the stirring group.

[0050] Further, referring to Figures 5 to 8, a T-slot 211 is provided on the side wall of the cavity 23 corresponding to the slot 221, and the T-slot 211 extends along the first direction. The linkage member 51 is adapted to the T-slot 211, and the linkage member 51 is slidably installed in the T-slot 211 along the first direction. By setting the T-slot 211, the linkage member 51 can be limited so that it can only move along the first direction.

[0051] Furthermore, the linkage member 51 is detachably connected to the locking member 4. This arrangement facilitates installation and disassembly.

[0052] Furthermore, the specific form of driving the linkage member 51 to move is not limited. It can be an electric cylinder, a hydraulic cylinder or a pneumatic cylinder arranged in the cavity 23, and the linkage member 51 can be driven to move by the above mechanism, or it can be manually driven. In this embodiment, please refer to Figures 5 to 9. A connecting member 212 is also provided in the cavity 23, and the connecting member 212 is provided with a threaded hole 2121; the trough type ore washing machine for laterite nickel ore also includes a screw 52, ​​one end of the screw 52 is rotatably connected to the linkage member 51, and the screw 52 is threadedly engaged with the connecting member 212 to drive the linkage member 51 to slide through the screw 52. The connecting member 212 is fixedly installed in the cavity 23, the screw 52 is threadedly engaged with the connecting member 212, and one end of the screw 52 is rotatably connected to the linkage member 51 along the axis in the first direction. In this way, when the screw 52 rotates, the linkage member 51 can be driven to move along the first direction, and the linkage member 51 can be prevented from being driven to rotate by the screw 52. In addition, the screw 52 has a certain locking and limiting function to prevent the linkage member 51 from accidentally moving.

[0053] Furthermore, since the screw 52 is located in the cavity 23 and both ends of the rotating shaft 2 are connected to the side walls of the cleaning tank 11, in order to facilitate the driving of the screw 52 to rotate, in this embodiment, please refer to Figures 5 to 8, the trough type ore washing machine for laterite nickel ore also includes a first connecting shaft 53, a second connecting shaft 54, a driving bevel gear 55 and a driven bevel gear 56, the first connecting shaft 53 is rotatably installed on the circumferential side of the rotating shaft 2, and one end of the first connecting shaft 53 extends into the cavity 23, the driving bevel gear 55 is connected to the end of the first connecting shaft 53 located in the cavity 23, the second connecting shaft 54 ​​and the screw 52 are relatively movable in their radial direction and are synchronously rotated in the circumferential direction, the driven bevel gear 56 is connected to one end of the second connecting shaft 54, and the driving bevel gear 55 and the driven bevel gear 56 are meshed. During specific use, the end of the first connecting shaft 53 located on the outside of the rotating shaft 2 can be rotated, thereby driving the active bevel gear 55 and the driven bevel gear 56 to engage, and the second connecting shaft 54 ​​can drive the screw 52 to rotate circumferentially, thereby driving the linkage 51 to move along the first direction, and since the second connecting shaft 54 ​​and the screw 52 move relative to each other along their radial directions, the second connecting shaft 54 ​​can be prevented from interfering with the screw 52.

[0054] Furthermore, an inner hexagonal groove or an outer hexagonal protrusion is provided at one end of the first connecting shaft 53 located outside the rotating shaft 2 . This arrangement makes it convenient to use a tool to rotate the first connecting shaft 53 .

[0055] Furthermore, the specific form of relative movement of the second connecting shaft 54 ​​and the screw rod 52 along their radial directions is not limited. In this embodiment, referring to Figures 5 to 8, a mounting hole is provided at one end of the screw rod 52 along its axial direction, and a fixing portion is formed on the inner wall of the mounting hole. A mounting portion 43 is provided on the outer periphery of the second connecting shaft 54. The second connecting shaft 54 ​​is slidably mounted in the mounting hole. The mounting portion 43 and the fixing portion cooperate to limit the rotation of the connector 212 relative to the second connecting shaft 54. In this embodiment, an internal spline is provided in the mounting hole, and the internal spline constitutes the fixing portion. The outer periphery of the second connecting shaft 54 ​​is provided with an external spline, and the external spline constitutes the mounting portion 43. Through the spline cooperation, the second connecting shaft 54 ​​and the screw rod 52 can move relative to each other along the first direction, and the second connecting shaft 54 ​​and the screw rod 52 can rotate synchronously.

[0056] Furthermore, since the rotating shaft 2 is longer and the number of the blades 3 in its radial direction is larger, the length of the entire linkage 51 is longer, which is not conducive to driving the linkage 51 to move. In this embodiment, the multiple blades 3 in the radial direction can be divided into multiple groups, each group is provided with the linkage 51, the screw 52, ​​the first connecting shaft 53, the second connecting shaft 54, the driving bevel gear 55 and the driven bevel gear 56, so that the length of the linkage 51 can be reduced, which is conducive to driving the linkage 51 to move.

[0057] Furthermore, a sealing member is provided between the blade 3 and the slot 221. In this embodiment, the sealing member is a sealing ring, which is sleeved on the outer periphery of the connecting section 32 and located between the abutting side and the outer periphery of the rotating shaft 2. The provision of the sealing ring can further seal the slot 221 to prevent water leakage.

[0058] Furthermore, in this embodiment, referring to Figures 7 and 8, the locking member 4 includes a locking portion 41, a connecting portion 42, and a mounting portion 43 connected in sequence. The locking portion 41 and the mounting portion 43 are spaced apart, and the connecting portion 42 connects one end of the locking portion 41 and the mounting portion 43, respectively. The mounting portion 43 is movably mounted on the side wall of the cavity 23 so that when the locking member 4 moves toward the blade 3, the locking portion 41 extends into the locking hole 321. Specifically, the mounting portion 43 is detachably connected to the linkage member 51, and the locking member 4 is generally U-shaped, thereby facilitating the locking portion 41 to extend into the locking hole 321 and avoiding interference between the locking member 4 and the blade 3.

[0059] Furthermore, in order to improve the connection strength between the locking member 4 and the blade 3, in this embodiment, referring to FIG9 , a limiting plate 213 is further provided in the cavity 23. The limiting plate 213 has limiting holes 2131 corresponding to the locking holes 321, so that when the locking member 4 moves toward the blade 3, the locking portion 41 sequentially extends into the locking hole 321 and the limiting hole 2131. This arrangement can improve the tensile strength of the locking portion 41 and prevent the blade 3 from breaking the locking portion 41 due to external forces.

[0060] Furthermore, one end of the locking portion 41 is configured to be tapered, which facilitates the locking portion 41 to extend into the locking hole 321 .

[0061] Furthermore, in this embodiment, the rotating shaft 2 includes a main body 21, a sleeve 22, and two connecting flanges. The main body 21 is provided with a groove on its outer periphery, and the groove extends along its length. The sleeve 22 is sleeved on the outer periphery of the main body 21. The main body 21 and the sleeve 22 are detachably connected. The two connecting flanges are detachably connected to the ends of the sleeve 22. The sleeve 22, the main body 21, and the two connecting flanges together enclose the cavity 23. The two connecting flanges are rotatably connected to the two side walls of the cleaning tank 11, and the power unit 6 is connected to one of the connecting flanges. The main body 21 is detachably connected to the sleeve 22, and the two connecting flanges are detachably connected to the ends of the sleeve 22. This configuration facilitates assembly and subsequent maintenance of the entire device.
