[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1, reference Figure 1 and Fig.10 , a conveying mechanism control system is provided, including a conveying belt machine 101; a first motor 102 and a second motor 103, both of which are connected to the conveying belt machine 101 in a transmission manner; a first box transformer 104; the first box transformer 104 is electrically connected to the first motor 102; and a second box transformer 105; the second box transformer 105 is electrically connected to the second motor 103. It also includes a first mobile box transformer 106 and a second mobile box transformer 107; the first mobile box transformer 106 is electrically connected to the first box transformer 104; the second mobile box transformer 107 is electrically connected to the second box transformer 105. The first motor 102 is installed at one end of the conveying belt machine 101, and the second motor 103 is installed at the other end of the conveying belt machine 101.

[0035] The first motor 102 is arranged at the head of the conveyor belt machine 101; the second motor 103 is arranged at the tail of the conveyor belt machine 101; the first box transformer 104 is electrically connected to the first motor 102 to provide power to the first motor 102; the second box transformer 105 is electrically connected to the second motor 103 to provide power to the second motor 103; and the backup power supply 108 is electrically connected to the first box transformer 104; wherein, when the first box transformer 104 loses power, the backup power supply 108 provides power to the first box transformer 104, thereby ensuring that the program control station of the first box transformer 104 functions normally, and the second motor 103 can independently drive forward and reverse operation, so that the conveyor belt machine 101 can operate normally. The motor control system also includes: a first mobile box transformer 106 and a second mobile box transformer 107. The first mobile box transformer 106 is electrically connected to the first box transformer 104 to provide power to the first box transformer 104 ; the second mobile box transformer 107 is electrically connected to the second box transformer 105 to provide power to the second box transformer 105 .

[0036] The motor control system of this solution increases the diversity of the operating modes of the motor of the conveyor belt machine 101 to ensure that the expected output can be reliably achieved under extreme conditions and to ensure stable production. A reliable backup power supply 108 is obtained from the power distribution room near the first box transformer 104 to ensure that the programmable control station of the first box transformer 104 functions normally in the event of a power failure. Even if the motor at the head of the conveyor belt machine 101 loses power and cannot operate, the second motor 103 at the tail of the conveyor belt machine 101 can independently drive forward and reverse operations, thereby ensuring the normal operation of the conveyor belt machine 101 and the normal stacking and reclaiming operations and external loading tasks of the bucket wheel excavator, thereby achieving a double insurance effect.

[0037] Example 2, reference Figures 2 to 9 This embodiment is different from the first embodiment in that, in order to facilitate maintenance, the first motor 102 and the second motor 103 are installed at the same end of the conveyor belt machine 101.

[0038] The conveying mechanism control system also includes a transmission mechanism 200, which is symmetrically connected to the conveyor belt machine 101 and is used to drive the conveyor belt machine 101; an elastic output mechanism 300, which is used to transmit and connect the first motor 102 and the second motor 103 to two symmetrical transmission mechanisms 200 respectively; a trigger mechanism 400, which is connected to the transmission mechanism 200 and offsets the elastic output mechanism 300; and an actuator 500, which is connected to the trigger mechanism 400.

[0039] In this embodiment, there are two transmission mechanisms 200, and the first motor 102 and the second motor 103 are both provided with an elastic output mechanism 300. The first motor 102 and the second motor 103 are respectively connected to the two transmission mechanisms 200 through the elastic output mechanism 300 to drive the conveyor belt machine 101. When one of the motors is working, the trigger mechanism 400 is working, and the other trigger mechanism 400 can be pushed by the actuator 500, so that the transmission relationship between the other motor and the transmission mechanism 200 is disconnected. Therefore, in normal operation, only one of the first motor 102 and the second motor 103 is involved in the driving work. For example, the first motor 102 is working and the second motor 103 is in a standby state. When the first motor 102 fails, the first motor 102 stops. At this time, the second motor 103 can replace the first motor 102 to drive the conveyor belt machine 101, and in this process, the connection between the first motor 102 and the transmission mechanism 200 is disconnected by the actuator 500, so that the staff can repair the first motor 102 without stopping the machine.

[0040] The trigger mechanism 400 includes a corotating shaft 401 connected to the transmission mechanism 200, a sliding member 402 slidably arranged on the corotating shaft 401, and a pushing member 403 connected to the sliding member 402; the actuator 500 includes an inner ring 501 connected to the sliding member 402, an outer ring 502 installed on the conveyor belt machine 101, a centrifugal member 503 movably installed on the inner ring 501, an expansion member 504 arranged on the outer ring 502, and a contact buckle 505 connected to the expansion member 504.

[0041] Because the co-rotating shaft 401 is connected to the transmission mechanism 200, when the transmission mechanism 200 rotates, it can drive the co-rotating shaft 401 to rotate synchronously, and the co-rotating shaft 401 can drive the sliding member 402 to rotate, and the sliding member 402 drives the inner ring 501 to rotate. When the inner ring 501 rotates, the centrifugal member 503 moves in the direction away from the center of the inner ring 501 under the action of centrifugal force. In this process, the centrifugal member 503 will push the expansion member 504 to move in the direction away from the center of the outer ring 502. When the expansion member 504 moves, it can drive the resistance buckle 505 to move, and the movement of the resistance buckle 505 pushes another sliding member 402 to move. At this time, due to the movement of the other sliding member 402, the corresponding pushing member 403 will push the elastic output mechanism 300 to disconnect from the transmission mechanism 200. Therefore, when one of the motors is working, the other motor will disconnect the transmission connection relationship with the conveyor belt machine 101, so as to facilitate non-stop maintenance.

[0042] It should be further explained that the outer ring 502 is fixedly mounted on the conveyor belt machine 101 and is concentric with the inner ring 501 . The outer ring 502 can be mounted on the conveyor belt machine 101 through a bracket.

[0043] The sliding member 402 includes a front end body 402a slidably mounted on the same rotating shaft 401, an extension bar 402b connected to the front end body 402a, a rear end body 402c connected to the extension bar 402b, and a first spring 402d arranged between the front end body 402a and the same rotating shaft 401; the elastic output mechanism 300 includes a sliding output ring 301 slidably mounted on the first motor 102, and a second spring 302 that abuts against the sliding output ring 301; the sliding output ring 301 is driven by the second spring 302 to be connected to the transmission mechanism 200, and the pushing member 403 is connected to the rear end body 402c, and when the pushing member 403 moves, it can push the sliding output ring 301 to disconnect from the transmission mechanism 200.

[0044] The front end body 402a is connected to the inner ring 501, and is used to drive the inner ring 501 to rotate synchronously. The extension strip 402b connects the front end body 402a and the rear end body 402c, so that the front end body 402a and the rear end body 402c can move synchronously. The first spring 402d is used to limit the position of the entire sliding member 402, so that the entire sliding member 402 will not interfere with the elastic output mechanism 300 in the absence of external force.

[0045] The second spring 302 applies pressure and thrust to the sliding output ring 301, so that the sliding output ring 301 maintains a transmission connection relationship with the transmission mechanism 200. When the inner ring 501 is subjected to a thrust in the direction of the motor, it can be installed on the first spring 402d. At the same time, the front end body 402a, the extension bar 402b, the rear end body 402c, and the pushing member 403 move in the direction of the motor. In this process, the pushing member 403 can push the sliding output ring 301 to disconnect the connection relationship with the transmission mechanism 200.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Example 3, reference Figures 2 to 9 This embodiment is different from the above embodiments in that: the centrifugal member 503 includes a movable column 503a installed on the inner ring 501, and a third spring 503b connected to the movable column 503a; the expansion member 504 is installed on the outer ring 502 through an elastic connecting member 506; a groove 504a is provided on the expansion member 504, and a limiting side groove 504b is provided in the expansion member 504 and the groove 504a; a limiting column 505a is provided on the abutment buckle 505, and the limiting column 505a extends to the inner side of the limiting side groove 504b.

[0048] Under the limitation of the third spring 503b, the movable column 503a will not contact the expansion piece 504 without being affected by the centrifugal force. When the first motor 102 rotates, the first motor 102 drives the corresponding transmission mechanism 200 to rotate, the transmission mechanism 200 drives the same rotating shaft 401 to rotate, the same rotating shaft 401 drives the inner ring 501 to rotate, and the rotation of the inner ring 501 applies centrifugal force to the movable column 503a. During the rotation process, the movable column 503a pushes the expansion piece 504 to move away from the center of the outer ring 502. In this process In the embodiment, under the influence of the limiting side groove 504b, the contact buckle 505 can be pushed to move toward the second motor 103, and the contact buckle 505 can push the inner ring 501 corresponding to the second motor 103, so that the inner ring 501 moves toward the second motor 103, and the front end body 402a, the extension strip 402b, the rear end body 402c, and the pushing member 403 move toward the motor direction. In this process, the pushing member 403 can push the sliding output ring 301 on the second motor 103 to disconnect from the transmission mechanism 200.

[0049] Among them, the limiting side groove 504b is arranged obliquely relative to the moving direction of the expansion piece 504. Therefore, when the expansion piece 504 moves away from the center of the outer ring 502, the limiting column 505a can apply a thrust to the resistance buckle 505, so that the resistance buckle 505 can move in a direction perpendicular to the moving direction of the expansion piece 504.

[0050] Specifically, a pushing protrusion 505 b is further provided on the resisting buckle 505 , and when the resisting buckle 505 moves, the pushing protrusion 505 b can push the inner ring 501 .

[0051] Furthermore, the transmission mechanism 200 includes a driving wheel 201, a passive wheel 202 connected to the conveyor belt machine 101, a transmission belt 203 connecting the driving wheel 201 and the passive wheel 202, and a slot 204 provided on the driving wheel 201; a gear ring 301a is installed on the sliding output ring 301, wherein the sliding output ring 301 is connected to the driving wheel 201 via the gear ring 301a and the slot 204, and when the pushing member 403 pushes the sliding output ring 301 in a direction away from the driving wheel 201, the transmission connection relationship between the sliding output ring 301 and the driving wheel 201 will be disconnected.

[0052] The rest of the structure is the same as that of Example 2.
