[0031] Example 3 Reference Figures 1-6 This embodiment provides a loading and unloading platform system for electric shovels, including a control device 203. Specifically, after the electric shovel extracts a single ore, it unloads it above the feed plate 203a. During the unloading process, the guide plate 203a-1 guides the ore to the turning chamber 203b. The turning chamber 203b is rotatable. During rotation, a gap may occur between the turning chamber 203b and the guide plate 203a-1. A hinge plate 203c is used to fill the gap between the turning chamber 203b and the guide plate 203a-1 to prevent material from falling from the side. The hinge plate 203c consists of a fixed block 203c-1 and a movable plate 203c-2, which are hinged together. An elastic element 203c-3 connects the fixed block 203c-1 and the movable plate 203c-2. The movable plate 203c-2 is in constant contact with the guide plate 203a-1 during the rotation of the steering chamber 203b through the action of the elastic element 203c-3.

[0032] Preferably, a first movable plate 203d and a second movable plate 203e are provided, each including a plate body and a rotating column. The plate body is fixedly connected to one end of the rotating column, and the other end of the rotating column passes through a second gear 203i and a third gear 203j. The first movable plate 203d and the second movable plate 203e are used to prevent material from falling into the other two material pipes 202c when it exits from below the turning chamber 203b. Figure 4 As shown, when the steering chamber 203b is aligned with the middle second pipe 202c-2, the first moving plate 203d and the second moving plate 203e block the first pipe 202c-1 and the third pipe 202c-3 respectively, leaving only the second pipe 202c-2 open.

[0033] The control device 203 includes a rotary motor 203f and a telescopic motor 203g. The rotary motor 203f is fixedly connected to the steering chamber 203b, and the telescopic motor 203g is fixedly connected to the steering chamber 203b, the first moving plate 203d, and the second moving plate 203e. It also includes a first gear 203h, a second gear 203i, and a third gear 203j. The first gear 203h is fixedly connected to the rotating shaft 203b-1. The second gear 203i and the third gear 203j are respectively fixedly connected to two rotating columns on the two first moving plates 203d and the second moving plate 203e, and the second gear 203i and the third gear 203j mesh with the first gear 203h.

[0034] The rotary motor 203f drives the first gear 203h and the rotating shaft 203b-1 to rotate. The rotating shaft 203b-1 drives the steering chamber 203b to rotate clockwise or counterclockwise within a limited angle within the feed plate 203a. The second gear 203i and the third gear 203j mesh with the first gear 203h. When the first gear 203h rotates, the second gear 203i and the third gear 203j also rotate in the opposite direction. The second gear 203i and the third gear 203j are respectively connected to the rotating columns on the two first moving plates 203d and the second moving plate 203e. When the second gear 203i and the third gear 203j rotate, they also drive the two rotating columns, as well as the first moving plates 203d and the second moving plates 203e, to rotate. The first moving plates 203d and the second moving plates 203e pass through the moving groove 203a-3 and rotate within the moving groove 203a-3. That is, when the steering chamber 203b rotates clockwise to face the first pipe 202c-1, the two first moving plates 203d and the second moving plate 203e rotate counterclockwise to be above the second pipe 202c-2 and the third pipe 202c-3.

[0035] Specifically, the first pipe 202c-1 and the third pipe 202c-3 each correspond to two loading and unloading vehicles. After the electric shovel excavates a single type of ore, it reaches the loading and unloading vehicle through the feed plate 203a, the steering chamber 203b, and either the first pipe 202c-1 or the third pipe 202c-3. The second pipe 202c-2 is the discharge cylinder for secondary sorting of mixed ore. After the electric shovel excavates mixed ore, it selects the second pipe 202c-2 to discharge ore to the secondary sorting platform. The control device 203 includes a rotary motor 203f and a telescopic motor 203g. The rotary motor 203f is fixedly connected to the steering chamber 203b, and the telescopic motor 203g is fixedly connected to the steering chamber 203b, the first moving plate 203d, and the second moving plate 203e. The control device 203 also includes electromagnetic blocks 203k disposed on the inner walls of both sides of the feed plate 203a. The two electromagnetic blocks 203k are electrically connected to the telescopic motor 203g and cooperate with the first moving plate 203d and the second moving plate 203e.

[0036] When the first moving plate 203d and the second moving plate 203e use magnetically attractable materials and require the use of the second pipe 202c-2, the operator energizes the electromagnetic blocks 203k on both sides of the inner wall of the feeding plate 203a. The rotary motor 203f controls the steering chamber 203b to rotate to the farthest end on one side of the feeding plate 203a. The first moving plate 203d and the second moving plate 203e also move to the farthest end on the other side of the feeding plate 203a accordingly. The first moving plate 203d comes into contact with the electromagnetic block 203k and is attracted. At this time, the telescopic motor 203g starts, and the telescopic motor 203g pushes the first telescopic rod 302a and the second telescopic rod 203g-2 forward, while the third telescopic rod 203g-3 remains stationary. When the first telescopic rod 302a and the second telescopic rod 203g-2 move forward, they drive the rotating shaft 203b-1 to move into the rotating shaft groove 203b-3, and also drive the rotating column connected to the second telescopic rod 203g-2 to move into the rotating column groove.

[0037] When the first gear 203h on the rotating shaft 203b-1 and the third gear 203j on the rotating column connected to the third telescopic rod 203g-3 are completely disengaged, the rotating motor 203f rotates in the opposite direction, driving the steering chamber 203b to rotate to the farthest end on the other side of the feed plate 203a. The second moving plate 203e also moves in the opposite direction to the farthest end opposite to the steering chamber 203b, and is attracted after contacting the electromagnetic block 203k.

[0038] At this point, the first moving plate 203d and the second moving plate 203e respectively block the first pipe 202c-1 and the third pipe 202c-3, leaving the area above the second pipe 202c-2 open. Then, using the telescopic motor 203g to pull the second telescopic rod 203g-2 back to its initial position, the rotary motor 203f rotates the discharge port of the steering chamber 203b above the second pipe 202c-2, allowing the second pipe 202c-2 to be used.

[0039] If you wish to reuse the first pipe 202c-1 and the third pipe 202c-3, reverse the above procedure until the two first moving plates 203d and the second moving plate 203e are in contact, then disconnect the power supply to the electromagnetic block 203k.

[0040] Preferably, the steering chamber 203b further includes a connecting plate 203b-4 sleeved on the rotating shaft 203b-1, the connecting plate 203b-4 not rotating with the rotating shaft 203b-1, a second elastic element 203b-5 fixedly connected at one end to the connecting plate 203b-4, and a wedge block 203b-6 connected at the other end of the second elastic element 203b-5; a sliding block 203a-4 is also provided on the feed plate 203a, the sliding block 203a-4 is fixed on the inner wall of the feed plate 203a and cooperates with the wedge block 203b-6.

[0041] When the telescopic motor 203g starts and drives the rotating shaft 203b-1 to move, the rotating shaft 203b-1 also simultaneously pushes the connecting plate 203b-4 forward. The connecting plate 203b-4, the second elastic element 203b-5, and the wedge block 203b-6 move forward. The wedge block 203b-6 slides along the upper part of the sliding block 203a-4, and the protrusion on the upper part of the wedge block 203b-6 will press against the hinge plate 203c, making the hinge plate 203c and the guide plate 203a-1 fit more tightly and better prevent material leakage. Furthermore, even when the elastic element 203c-3 on the hinge plate 203c ages and fails, the overall structure can still achieve its intended effect.
