Abstract
Description
Technical Field
[0001] This utility model relates to the field of loading and unloading equipment technology, and more specifically to a loading and unloading hopper device used in conjunction with a forklift. Background Technology
[0002] Currently, forklifts are frequently used to load ordinary hoppers when loading, unloading, and transferring goods. However, unloading ordinary hoppers requires first removing the hopper, then using the fork tines to lift the edge of the hopper, raising it 90°, and then using the fork tines to push the hopper over, rotating it 180° to achieve complete unloading. After unloading, the above steps need to be repeated to rotate the hopper for reuse. This not only requires a high level of skill from the forklift operator, but the entire process is also cumbersome, time-consuming, and inefficient.
[0003] Therefore, providing an efficient loading and unloading hopper device that can be used with forklifts is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the present invention provides a loading and unloading hopper device for use with a forklift, which can unload materials efficiently and conveniently.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A loading and unloading hopper device for use with a forklift includes a forklift and a hopper, and further includes a rotating shaft, two guide grooves and a limiting strip. The rotating shaft is horizontally fixed to the rear bottom of the hopper. Both guide grooves are rotatably connected to the rotating shaft, and the two guide grooves correspond to the positions of two fork teeth of the forklift, respectively. Any one or both guide grooves extend to the rear side of the hopper in the height direction. One end of the limiting strip is fixedly connected to the center of the rear bottom of the hopper, and the other end of the limiting strip is hooked onto the forklift.
[0007] By adopting the above solutions, the beneficial effects of this utility model are:
[0008] It enables convenient and rapid unloading of bulk materials by forklift loading, thus improving work efficiency.
[0009] Furthermore, there are two rotating shafts, which are horizontally fixed at both ends of the rear bottom of the hopper; the two guide grooves are rotatably connected to the two rotating shafts respectively.
[0010] Furthermore, the limiting bar is a limiting chain.
[0011] Furthermore, when the fork tooth end is retracted to a position inside or outside the guide groove, the limiting strip is taut.
[0012] Furthermore, the longitudinal section of the hopper is trapezoidal; the rear side of the hopper is square.
[0013] Furthermore, the guide groove is square in shape and has a guide channel through which the fork teeth pass. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1-4As shown in the figure, this utility model discloses a loading and unloading hopper device used in conjunction with a forklift, including a forklift, a hopper 1, a rotating shaft 2, two guide grooves 3, and a limiting strip 4. The rotating shaft 2 is horizontally fixed to the rear bottom of the hopper 1; both guide grooves 3 are rotatably connected to the rotating shaft 2, and the two guide grooves 3 correspond to the positions of the two fork teeth 5 of the forklift; any one or both guide grooves 3 extend to the rear side of the hopper 1 in the height direction; one end of the limiting strip 4 is fixedly connected to the center of the rear bottom of the hopper 1, and the other end of the limiting strip 4 is hooked onto the forklift. This utility model realizes convenient and fast unloading of bulk materials loaded by a forklift, improving work efficiency.
[0021] To increase the overall structural stability, there are two rotating shafts 2, which are horizontally fixed at both ends of the rear bottom of the hopper 1; two guide grooves 3 are rotatably connected to the two rotating shafts 2 respectively.
[0022] Specifically, the limiting bar 4 is a limiting chain. When the end of the fork tooth 5 is retracted to the inside or outside of the guide groove 3, the limiting bar 4 is in a taut state.
[0023] Specifically, the longitudinal section of hopper 1 is trapezoidal; the rear side of hopper 1 is square. Of course, hoppers of different sizes and shapes can be designed according to different materials to meet the requirements of rapid unloading of different materials.
[0024] Specifically, the guide groove 3 is square in shape and has a guide channel through which the fork tooth 5 passes.
[0025] The working process of this utility model:
[0026] 1) Insert the fork 5 of the forklift into the guide groove 3 and extend it to the bottom of the hopper 1. Attach the limit strip 4 to the forklift anchor point. After the hopper 1 is filled with material, the forklift will transport the hopper 1 to the unloading point.
[0027] 2) After reaching the unloading point, the forklift reverses, causing the end of the fork tooth 5 to retract into the guide groove 3 or the end of the guide groove 3, while the limit bar 4 is taut. Then, the forklift stops reversing and the brake is applied.
[0028] 3) Slowly raise the fork 5, and the hopper 1 will rotate around the pivot 2 under the action of gravity; stop when the hopper 1 is completely off the ground. At this time, the hopper 1 will rotate about 150°, and all the material in the hopper 1 can be poured out.
[0029] 4) After the hopper 1 is completely unloaded, the forklift reverses, the fork teeth 5 move backward, and the fork teeth 5 are lowered at the same time. After the hopper 1 touches the ground, it begins to flip and gradually flips back to the upright position. Repeat the above actions to achieve repeated loading and unloading.
[0030] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
