Description

Technical Field

[0001] The invention relates to the technical field of ship unloader unloading, and more particularly to a ship unloader stabilizing unloading flow device. Background Art

[0002] Ship unloader is a special machine that uses continuous conveying machinery to make a head that can lift materials, or has the ability to take materials by itself, or is equipped with a material taking and feeding device to continuously take materials out of the ship's cabin, and then unload them to the arm or frame and transport them to the shore main conveying system. The use of ship unloader can greatly improve the unloading efficiency, and the minimum dust pollution can keep the environment clean, which is efficient and environmentally friendly.

[0003] When the ship unloader is unloading, the grab bucket grabs the material into the bucket, and then puts the material into the hopper. The material in the hopper falls into the vibrating feeder, and the vibrating motor drives the vibrating feeder to vibrate. The material is evenly distributed in the vibrating feeder due to the vibration and is evenly discharged toward the conveyor belt at the bottom. When using the existing ship unloader unloading device, due to the different volumes of materials, larger block materials are easily stuck at the outlet when passing through the hopper into the vibrating feeder, causing blockage. When the vibrating feeder falls into the conveyor belt, the belt on the conveyor belt will be damaged due to the large volume of the fallen block materials. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a ship unloader stable unloading flow device which can adjust the gap size between the hopper and the unloading platform through the cooperation of the winding roller and the unloading platform, and can weaken the falling force of large pieces of material before transporting them through the cooperation of the unloading platform and the shock-absorbing part, thereby avoiding blockage of the outlet caused by excessive material and effectively protecting the components in the conveying part.

The top of the unloading frame 1 is fixedly connected with a plurality of mounting seats 11 adapted to the winding rollers 10, and each mounting seat 11 is provided with a tensioning rod 12 facing the inner side of the unloading frame 1, and the end of each tensioning rod 12 is fixedly connected to the unloading frame 1. The top of the unloading frame 1 is provided with threading holes 13 corresponding to the plurality of tensioning rods 12, and a linkage member 14 is provided in the unloading frame 1. The right side of the unloading frame 1 is provided with There is a shock absorbing member 24, the linkage member 14 includes a discharge platform 15 coaxially arranged with the discharge frame 1, a plurality of sieve holes 16 are provided on the inner bottom surface of the discharge platform 15, and the side of the discharge platform 15 is evenly and symmetrically fixedly connected with straight plates 17 corresponding to the threading holes 13, each straight plate 17 is hinged with a hinge rod 18 at the top, each hinge rod 18 is fixedly connected with a connecting shaft 19 at the top, a stopper 20 is fixedly connected to the end of the connecting shaft 19, and a first spring 21 is fixedly connected to the bottom of the stopper 20, and the connecting shaft 1 A matching sleeve 22 is slidably connected to the 9-week side surface, the first spring 21 is fixedly connected to the inner bottom surface of the matching sleeve 22, a matching pull rope 23 is installed between the winding roller 10 and the matching sleeve 22, a plurality of slide grooves 32 matching the matching sleeves 22 are opened in the unloading rack 1, the matching sleeve 22 is slidably connected to the slide groove 32, a unloading hopper 33 is fixedly connected to the axial position of the unloading rack 1, a vibrating member 35 is fixedly connected to the side of the unloading platform 15, and a conveying member 34 is arranged at the axial position of the bottom of the unloading rack 1.

[0033] The working principle of the first embodiment is as follows: a grab bucket is used to grab materials and put them into the hopper 33. There is a certain gap between the hopper 33 and the discharge platform 15. The materials in the hopper 33 fall into the discharge platform 15. The vibration member 35 includes a motor, a pulley, a rotating shaft, a belt, and an eccentric wheel. The motor drives the rotating shaft to rotate, and the rotating shaft drives the pulley to rotate. The pulley drives the eccentric wheel to rotate through the belt, and a vibration force is applied to the discharge platform 15, so that the discharge platform 15 is in a vibrating state. When vibrating, the discharge platform 15 is relatively unstable. When the discharge platform 15 vibrates, it drives the connecting shaft 19 to move in the matching sleeve 22. Since the connecting shaft 19 is slidably connected to the matching sleeve 22, the first spring 21 is compressed by the block 20 during vibration, so that the discharge platform 15 remains stable during vibration. The materials fall into the discharge platform 15, and are evenly dispersed in the discharge platform 15 due to the vibration, and move toward the outlet end according to the inclination angle of the discharge platform 15. The materials are dropped at different rates, and the particles of different sizes are different. When larger block materials appear, the motor 6 drives the rotating rod 4 to rotate. The two symmetrical worms 5 are respectively a left-handed worm 5 and a right-handed worm 5. The rotation of the worm 5 drives the two gears 8 to rotate with each other, and the gear 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the winding roller 10 on its peripheral side to retract and release the pull rope 23, and the pull rope 23 pulls the matching sleeve 22 to move. Due to the different rotation directions of the two rotating shafts 9, the winding roller 10 on one side of the discharge frame 1 is wound, and the winding roller 10 on the other side is released. Small pieces of material fall into the conveying member 34 through the sieve hole 16. The conveying member 34 includes a conveying motor, a conveyor belt, and a transfer wheel. The conveying wheel is adapted to the conveyor belt. The pull rope 23 pulls the discharge platform 15 for angular deviation. By changing the angle formed between the discharge platform 15 and the hopper 33, it can avoid that larger pieces of material are blocked during the drop.

[0034] Embodiment 2

[0035] See also Figure 5-9 The second embodiment is improved on the basis of the first embodiment as follows. Specifically, the shock absorbing member 24 includes a shock absorbing box 25 arranged on the side of the unloading rack 1. A plurality of telescopic rods 26 are fixedly connected to the inner bottom surface of the shock absorbing box 25. A plurality of second springs 27 adapted to the telescopic rods 26 are fixedly connected to the inner bottom surface of the shock absorbing box 25. A slide plate 28 is slidably connected to the inner wall of the shock absorbing box 25. The bottom surface of the slide plate 28 is fixedly connected to the second spring 27 and the telescopic rod 26. Two connecting rods 29 are symmetrically fixedly connected to the side of the shock absorbing box 25. The other ends of the two connecting rods 29 are rotatably connected to the unloading rack 1. A side plate 30 is fixedly connected to the side of the unloading rack 1. A hydraulic cylinder 31 is hinged on the top of the side plate 30. The top of the hydraulic cylinder 31 is hinged to the bottom surface of the shock absorbing box 25.

[0036] The working principle of the second embodiment of the present invention is as follows: the material is uniformly discharged toward the opening through the unloading platform 15. Small pieces of material have a small volume and mass and will not cause damage to the conveying member 34. They fall into the conveying member 34 through the sieve hole 16 for subsequent transportation. Larger pieces of material pass through the opening of the unloading platform 15 and fall onto the slide plate 28. The angle of the shock absorber box 25 is adjusted by adjusting the hydraulic cylinder 31. After the material falls into the slide plate 28, the slide plate 28 compresses the telescopic rod 26 and the second spring 27 inward to weaken the falling force. After the material falls into the conveying member 34 through the slide plate 28, the telescopic rod 26 and the second spring 27 can buffer the falling material, thereby improving the stability of the unloading of the ship unloader and avoiding damage during the period in the conveying member 34.
