Description

Technical Field

[0001] The present application relates to the technical field of material conveying equipment, and in particular to a ship loader with adjustable conveying stroke. Background Art

[0002] The ship loader is used to transport bulk materials from the port to the cabin of the ship moored at the port. When the width of the cabin is wide, the materials are generally transported to one side of the cabin along the width direction of the cabin first; when the materials in the cabin at the discharge end of the ship loader are accumulated to the mouth of the cabin, the ship loader is moved along the width direction of the cabin to allow the discharge end of the ship loader to move along the width direction of the cabin, so that the remaining positions of the cabin along the width direction of the cabin itself can be loaded, so as to improve the uniformity of material distribution in the cabin.

[0003] With regard to the above-mentioned related technologies, when it is necessary to load materials at other positions along the width direction of the cabin, the loader needs to be moved as a whole, which is laborious to operate and needs to be improved. Utility Model Content

[0007] By adopting the above technical solution, when the materials located below the discharge part are stacked to a specified height, the operating assembly controls the driving member so that the driving member drives the extension frame to move, thereby adjusting the position of the discharge part and the location of the drop point of the materials output by the discharge part; compared with the mobile frame as a whole, the operation is more convenient and labor-saving. In addition, the cables connected to the electrical components installed on the extension frame are stored in the drag chain, which is conducive to reducing the possibility of wear or entanglement of the cables due to contact with the extension frame or the mounting frame.

[0008] Preferably, the operating assembly includes a control box rotatably connected to the frame and an input member connected to the control box, wherein the input member is electrically connected to the controller; the axial direction of the rotating shaft of the control box is arranged along the length direction of the frame.

[0009] By adopting the above technical solution, when the input part needs to be operated, the control box can be rotated upward to reduce the possibility of the operator needing to squat or bend down, making the operation more convenient and labor-saving, which is conducive to improving the comfort of operation.

[0010] Preferably, the frame is provided with a fixed rod for axial sliding along the rotating shaft of the control box, and the fixed rod is connected to an elastic member for driving it to slide toward the control box; the control box is provided with a hemispherical groove for inserting one end of the fixed rod; a plurality of hemispherical grooves are arranged in sequence at intervals along the circumferential direction of the rotating shaft of the control box.

[0011] By adopting the above technical solution, when the control box is turned with force, the end wall of the fixed rod can slide relatively along the inner wall of the hemispherical groove, so that the fixed rod can be disengaged from the hemispherical groove, thereby allowing the control box to be rotated; when the operator rotates the control box until the hemispherical groove is aligned with the fixed rod, the elastic member has a force on the fixed rod to move the fixed rod in the direction of the hemispherical groove, so that the fixed rod can be inserted into the hemispherical groove, and at the same time, the end wall of the fixed rod can be kept in close contact with the inner wall of the hemispherical groove, thereby limiting the rotation of the control box, thereby reducing the need to support the control box by hand, and the operation is simpler and more labor-saving.

[0012] Preferably, the rack is provided with an electric control box, and the controller is located in the electric control box.

[0013] By adopting the above technical solution, the electric control box has a protective effect on the controller, which is helpful to reduce the possibility of the controller being wetted by liquids such as rain or contaminated by dust.

[0014] Preferably, the electric control box is slidably connected to the frame along the width direction of the frame, and the frame is provided with a locking assembly for fixing the electric control box.

[0015] By adopting the above technical solution, when the controller needs to be repaired, the locking assembly can be loosened to pull out the electric control box, which is beneficial to increase the operating space, thereby reducing the possibility of the rack interfering with the operation of the repair controller.

[0017] By adopting the above technical solution, the limit rod and the abutment rod cooperate with each other to clamp the electric control box, thereby limiting the sliding of the electric control box to achieve the effect of fixing the electric control box. By rotating the abutment rod, the abutment rod and the electric control box can be separated, so that the electric control box can slide in a direction away from the limit rod, so that the electric control box can be moved to the outside of the rack.

[0018] Preferably, the conveying device includes a rotating roller, a steering roller, a connecting roller, an output roller, a conveyor belt and a rotating assembly; the rotating roller and the steering roller are both rotatably connected to the frame, and the connecting roller and the output roller are both rotatably connected to the extension frame; the rotating roller is located at the loading part, and the output roller is located at the discharging part; the connecting roller and the steering roller are both located between the rotating roller and the output roller, and the connecting roller is located on the side of the steering roller close to the rotating roller; the conveyor belt successively passes around the rotating roller, the output roller, the connecting roller and the steering roller and is in a closed ring; the rotating assembly is used to drive the conveyor belt to move.

[0019] By adopting the above technical solution, when the driving member drives the extension frame to slide, the extension frame drives the output rod and the connecting roller to move synchronously to adjust the position of the output roller; under the action of the conveyor belt's own gravity, that is, the material on the conveyor belt, the transmission belt can always maintain contact with the peripheral walls of the rotating roller, the steering roller, the connecting roller and the output roller, so that the conveyor belt can continuously transport the material in the direction of the output roller.

[0020] Preferably, the rotating assembly includes a driving roller rotatably connected to the frame and a rotating motor for driving the driving roller to rotate; the rotating motor is connected to the frame; and the peripheral wall of the driving roller abuts against the conveyor belt.

[0021] By adopting the above technical solution, the rotating motor drives the driving roller to rotate, so that the driving roller can drive the conveyor belt to move.

[0022] Preferably, the conveying device comprises an upper belt conveyor and a lower belt conveyor located below the upper belt conveyor; the bracket of the lower belt conveyor is connected to the frame, and the bracket of the upper belt conveyor is connected to the extension frame.

[0023] By adopting the above technical solution, the driving member drives the extension frame to move, so that the extension frame drives the lower belt conveyor to move, thereby adjusting the position of the output end of the lower belt conveyor, that is, the discharge portion. The upper belt conveyor can convey materials toward the extension frame, and the materials output from the discharge end of the upper belt conveyor automatically fall onto the conveyor belt of the lower belt conveyor, so that the conveyor belt of the lower belt conveyor conveys the materials to the position of the discharge portion, thereby allowing the materials to be discharged from the discharge portion into the cabin.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1.
