[0018] Lifting plate 4 is fixedly connected on the side wall of intermediate bin 10 side, and hydraulic lifting mechanism 5 is driven to connect lifting plate 4, to drive lifting plate 4 to lift. Flexible connecting pipe 2 and connecting cover plate 3 are movably connected with shutter 6, one side of shutter 6 is equipped with shutter valve 7, and shutter valve 7 is driven to connect shutter 6, to drive shutter 6 to turn on / off blanking tube 1 and feeding machine 20.

[0019] As shown in Figure 2As shown, the hydraulic lifting mechanism 5 comprises a first hydraulic cylinder 51, a second hydraulic cylinder 52, a first piston 511, and a second piston 521. Hydraulic oil is arranged in the first hydraulic cylinder 51 and the second hydraulic cylinder 52. The first hydraulic cylinder 51 is communicated with the second hydraulic cylinder 52 through a first channel at the bottom. The first piston 511 is arranged in the first hydraulic cylinder 51 and is in sliding connection with the inner wall of the first hydraulic cylinder 51. The first piston 511 can slide axially along the first hydraulic cylinder 51. The first piston 511 is connected with a lever handle 513 through a first piston rod 512, so that the first piston 511 is driven by the lever handle 513 to press the hydraulic oil in the first hydraulic cylinder 51 into the second hydraulic cylinder 52. The second piston 521 is arranged in the second hydraulic cylinder 52 and is in sliding connection with the inner wall of the second hydraulic cylinder 52. The second piston 521 can slide axially along the second hydraulic cylinder 52. The second piston 521 is connected with the lifting plate 4 through a second piston rod 522, so that the second piston 521 drives the lifting plate 4 to be lifted when the hydraulic oil in the first hydraulic cylinder 51 is pressed into the second hydraulic cylinder 52.

[0020] The contact area of the second piston 521 with the hydraulic oil is greater than the contact area of the first piston 511 with the hydraulic oil. According to Pascal's principle, when the external pressure changes, the pressure at any point in the liquid will change by the same amount as long as the liquid remains stationary. This means that in a closed container, the pressure exerted on the stationary liquid will be transmitted to each point simultaneously, thereby achieving force transmission and transformation. Therefore, the pressure of the hydraulic oil at the first piston 511 and the second piston 521 is the same, and the pressure is equal to the pressure divided by the area. When the contact area of the second piston 521 with the hydraulic oil is greater than the contact area of the first piston 511 with the hydraulic oil, the pressure applied to the first piston 511 is less than the pressure applied to the second piston 521. Therefore, only a small force needs to be applied to the lever handle 513 to lift the lifting plate 4, so that the soft connecting pipe 2 and the connecting cover plate 3 are separated from the feeder 20, and the feeder 20 can be quickly pulled out. This is convenient, time-saving and labor-saving.

[0021] A first one-way valve 54 is arranged in the first channel to flow from the first hydraulic cylinder 51 to the second hydraulic cylinder 52, so as to avoid the backflow of the hydraulic oil in the second hydraulic cylinder 52 and ensure the stability of the lifting plate 4. A second channel is arranged at the bottom of the first hydraulic cylinder 51 to communicate with an oil cylinder 53. A second one-way valve 55 is arranged in the second channel to flow from the oil cylinder 53 to the first hydraulic cylinder 51, so that the hydraulic oil in the oil cylinder 53 is sucked into the first hydraulic cylinder 51 by driving the first piston 511 through the lever handle 513, thereby increasing the lifting stroke of the lifting plate 4.

[0022] The lever handle 513 is hinged at one end to the first piston rod 512, the first hydraulic cylinder 51 is provided with a support rod 514, the lever handle 513 is hinged at the middle to the support rod 514, the lever handle 513 is detachably connected with the first piston rod 512 and the support rod 514, when the lever handle 513 is pressed down, the first piston rod 512 drives the first piston 511 to move up, the sealed working volume in the first hydraulic cylinder 51 is increased to form a partial vacuum, under the action of atmospheric pressure, the hydraulic oil in the oil cylinder 53 flows into the first hydraulic cylinder 51 to complete a oil suction action, then, when the lever handle 513 is lifted up, the first piston rod 512 drives the first piston 511 to move down to press the hydraulic oil in the first hydraulic cylinder 51 into the second hydraulic cylinder 52, drives the second piston 521 to move up, and the lifting plate 4 is lifted up by the second piston rod 522 to complete a lifting action.

[0023] The second hydraulic cylinder 52 is communicated with the oil cylinder 53 through a third channel, the third channel is provided with an electromagnetic valve 56, when the electromagnetic valve 56 is opened, the second hydraulic cylinder 52 is communicated with the oil cylinder 53 to enable the hydraulic oil in the second hydraulic cylinder 52 to be discharged into the oil cylinder 53, and the lifting plate 4 is lowered together with the second piston 521 under the action of gravity, when the lifting plate 4 is lowered to a specified position, the electromagnetic valve 56 is closed to disconnect the second hydraulic cylinder 52 from the oil cylinder 53, and the lifting plate 4 stops lowering to complete resetting.

[0024] The second hydraulic cylinder 52 is provided with an oil guide pipe 58 at one side, the second hydraulic cylinder 52 is communicated with one end of the oil guide pipe 58 through a fourth channel, the other end of the oil guide pipe 58 is communicated with the oil cylinder 53, and the fourth channel is provided with a pressure maintaining valve 57, when the first hydraulic cylinder 51 press the hydraulic oil into the second hydraulic cylinder 52 to move the second piston 521 to the top of the second hydraulic cylinder 52, if the hydraulic oil continues to be pressed into the second hydraulic cylinder 52, the hydraulic pressure in the second hydraulic cylinder 52 continues to increase to the threshold value of the pressure maintaining valve 57, the pressure maintaining valve is communicated, and the hydraulic oil in the second hydraulic cylinder 52 is pressed into the oil cylinder 53 through the oil guide pipe 58 to release the pressure in the second hydraulic cylinder 52 to prevent overpressure, and double protection is achieved.
