The feeding ports are arranged at intervals along the conveying direction of the air cushion machine, and a suitable feeding port can be selected according to the actual situation.

[0003] However, when the middle feeding port is not in use, it should not affect the material on the conveyor belt passing below it. Therefore, the hopper of the middle feeding port needs to be arranged higher to ensure that the material on the conveyor belt can pass below the hopper. However, if the hopper is set relatively high, the material output from the hopper is likely to splash out from the conveyor belt, causing waste. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a feeding device for an air cushion machine, aiming to fold the hopper for use in the middle feeding port.

[0026] The following details the implementation manners of the present utility model. The examples of the implementation manners are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0027] The following disclosure provides many different implementation manners or examples for implementing different solutions of the present utility model.

[0028] Referring to Figures 1 to 6 As shown, in one embodiment of the present utility model, an air cushion machine feeding device includes a cover plate 1 located above the conveyor belt 100. The cover plate 1 is provided with a feeding port 11 and a flange frame 2. The flange frame 2 is docked above the feeding port 11. A hopper 3 is hinged in the flange frame 2. The hopper 3 passes through the feeding port 11. The top end of the flange frame 2 is used to dock with an external feeding device. The inlet port 31 of the hopper 3 receives the material input from the top end of the flange frame 2. The outlet port 32 of the hopper 3 conveys the material onto the conveyor belt 100. A driving module 4 is provided on the flange frame 2. The driving module 4 is connected to the hopper 3 to drive the hopper 3 to swing. The swinging of the hopper 3 can change the height of its outlet port 32;

[0029] The external feeding device puts the material on top of the flange frame 2, and then it enters the feeding port 31 of the hopper 3. The hopper 3 passes through the feeding opening 11. The material then moves along the hopper 3 and is discharged from the discharge port 32 of the hopper 3, and then discharged onto the conveyor belt 100 to complete the feeding.

[0030] Since the hopper 3 can swing, when the middle feeding opening 11 needs to be fed, the discharge port 32 of the hopper 3 is made relatively low. At this time, the hopper 3 is close to the conveyor belt 100, and the material is smoothly put onto the conveyor belt 100. The other feeding openings 11 behind this feeding opening 11 do not operate, so there will be no material on the conveyor belt 100 that will be blocked by the hopper 3.

[0031] When the middle feeding opening 11 does not need to be fed, the discharge port 32 of the hopper 3 is made higher, and the hopper 3 will move away from the conveyor belt 100. The other feeding openings 11 behind this feeding opening 11 are operating, and the material on the conveyor belt 100 can pass under the hopper 3 and will not be blocked by the hopper 3.

[0032] In this embodiment, the hopper 3 includes an arc-shaped plate 33 that bends downward along the conveying direction of the conveyor belt 100. The arc-shaped plate 33 is recessed downward. Side plates 34 are provided on both sides of the arc-shaped plate 33 along its bending direction. A support plate 35 is connected between the two side plates 34. The lower end of the arc-shaped plate 33 and the support plate 35 form the discharge port 32, and the upper end of the arc-shaped plate 33 and the support plate 35 form the feeding port 31. The side plates 34 are rotatably connected to the flange frame 2.

[0033] After the material enters the feeding port 31, it will move along the arc-shaped plate 33 and then be discharged from the discharge port 32. In this structure, the hopper 3 conveys the material more smoothly.

[0034] In this embodiment, a notch 331 is provided at the lower end of the arc-shaped plate 33. The projection of the notch 331 on the horizontal plane is trapezoidal. When the material flows out, the middle part will first flow out in a small amount from the position of the notch 331 away from the lower end of the arc-shaped plate 33, thereby pressing down on the belt of the conveyor belt 100 to make the belt concave, and then flowing out from the two side edges of the notch 331 and being put onto the middle of the belt, to a certain extent avoiding the material from splashing out.

[0035] Specifically, a connecting shaft is provided on the side of the side plate 34 away from the arc-shaped plate 33, and the connecting shaft is rotatably connected to the flange frame 2.

[0036] In this embodiment, the driving module 4 includes a rotating shaft 41 provided on the flange frame 2, a motor 42 for driving the rotation of the rotating shaft 41, and a cable 43 that can be wound around the rotating shaft 41. The cable 43 is connected to the hopper 3, and the hopper 3 is driven to swing by the cable 43.

[0037] Specifically, the side plates 34 are provided with slots for connecting with the cable 43. The cable 43 drives the entire hopper 3 to swing by pulling the side plates 34. Moreover, slots are provided on both side plates 34, and two cables 43 are provided on the rotating shaft 41, corresponding to the two side plates 34 respectively. An annular guiding groove for winding the cable 43 is provided on the rotating shaft 41, which facilitates the winding of the cable 43. And in order to avoid the breakage of the cable 43, the cable 43 can be made of steel wire rope.

[0038] In this embodiment, a dust suction port 12 is provided on the cover plate 1. The feeding port 11 and the dust suction port 12 are arranged at intervals along the conveying direction of the conveyor belt 100. The dust suction port 12 is inclined upward along the conveying direction of the conveyor belt 100. The external air suction and dust removal pipe can be connected to the dust suction port 12, so as to suck away the dust generated during transportation. And the inclination direction of the dust suction port 12 is adapted to the conveying direction of the conveyor belt 100, and the dust generated by the conveyor belt 100 is easily introduced into the dust suction port 12.

[0039] In this embodiment, an observation window 21 is provided on the flange frame 2. The observation window 21 includes a peephole and an observation door covering the peephole. The situation of the hopper 3 can be observed by opening the observation door.

[0040] In this embodiment, a square hopper is provided at the top of the flange frame 2, which can guide the material to ensure that the material can enter the feeding port 31 of the hopper 3.

[0041] In this embodiment, two guiding plates 5 are provided on the inner side of the cover plate 1. The two guiding plates 5 are located on both sides of the hopper 3 along the conveying direction of the conveyor belt 100. An installation bracket 6 is provided on the inner side of the cover plate 1. The guiding plate 5 is hinged to the installation bracket 6. A pull rod 7 is movably connected to the cover plate 1, and the pull rod 7 is connected to the guiding plate 5 to drive the guiding plate 5 to swing. That is to say, pulling the pull rod 7 can adjust the position of the guiding plate 5.

[0042] When the guiding plate 5 is in the first posture, the end of the guiding plate 5 far from the installation bracket 6 can be in contact with the tape of the conveyor belt 100, or very close to the tape of the conveyor belt 100, so as to prevent the material on the tape from splashing out.

[0043] When the guiding plate 5 is in the second posture, the end of the guiding plate 5 far from the installation bracket 6 can be in contact with the cover plate 1, or very close to the cover plate 1. At this time, the guiding plate 5 does not hinder the material on the conveyor belt 100 from passing under it. In this posture, the discharge port 32 of the hopper 3 is also at a high position, and the feeding port 11 does not feed at this time.

[0044] In this embodiment, a tension spring 8 is connected between the guiding plate 5 and the installation bracket 6.

[0045] When the guide plate 5 is in the first posture, the tension spring 8 is stretched. At this time, the tension spring 8 has a tendency to make the guide plate 5 approach the tape of the conveyor belt 100, so that the guide plate 5 can maintain the first posture;

[0046] When the guide plate 5 is in the second posture, the tension spring 8 is also stretched. At this time, the tension spring 8 has a tendency to make the guide plate 5 approach the cover plate 1, so that the guide plate 5 can maintain the second posture;

[0047] When the pull rod 7 pulls the guide plate 5, it overcomes the pulling force of the tension spring 8 to make the guide plate 5 swing and switch different postures.

[0048] In this embodiment, an operation opening is provided on the cover plate 1, a sealing cover 13 is assembled in the operation opening, a through hole is provided on the sealing cover 13, and the pull rod 7 passes through it. Therefore, the pull rod 7 can be pulled externally to adjust the position of the guide rod.

[0049] In this embodiment, a corresponding observation window 21 may also be provided on the cover plate 1 to observe the situation of the guide plate 5.

[0050] In this embodiment, the guide plate 5 includes a hard plate body and an elastic plate body.
