Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an automatic unloading device. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, unloading hoppers are frequently used on construction sites, often for transporting sand, cement, bricks, and concrete.

[0003] For conventional unloading hoppers, since there is no gate frame structure to block the unloading end, materials are prone to spilling from the edge of the hopper during the unloading process. For construction projects, the falling of materials such as sand and gravel will cause unnecessary waste of materials and pose safety hazards to workers on the ground. Therefore, improvements are urgently needed. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an automatic unloading device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic unloading device, characterized in that it comprises:

[0007] The base has a hopper hinged to its third shaft. The hopper extends in the same direction as the third shaft and has a limiting plate.

[0008] The boom is raised, and one end of the boom is hinged to the hopper;

[0009] The door opening arm is connected to the hopper via a first shaft and a second shaft. The first shaft is hinged to the hopper, and the first shaft, the second shaft, and the third shaft are parallel to each other.

[0010] The lifting forearm is hinged at both ends to the other end of the lifting boom and the door opening arm, respectively.

[0011] The hydraulic cylinder has its two ends hinged to the base and the middle of the lifting boom, respectively.

[0012] Preferably, the door opening arm is provided with a recessed part, and when the side door is in the closed state, the recessed part of the door opening arm is adapted and fitted to the third shaft.

[0013] Preferably, when the hopper is not lifted and the side door is fully open, the lifting boom is in contact with the limiting plate.

[0014] Preferably, when the hydraulic cylinder lifts, the side door and the hopper rotate clockwise around their hinge axis in sequence; when the hydraulic cylinder lowers, the hopper and the side door rotate counterclockwise around their hinge axis in sequence.

[0015] Preferably, the hopper is provided with a recessed groove, and when the side door is closed, a portion of the second shaft is located in the recessed groove.

[0016] Preferably, the hinge shafts of the hopper, the hydraulic cylinder, the lifting boom, and the lifting arm are all parallel to the axial direction of the third shaft.

[0017] Preferably, the hopper located on the outer side wall of one end of the limiting plate is provided with reinforcing ribs.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared with existing technologies, by realizing the automatic opening and closing of the hopper door during the unloading process, it is possible to avoid material spilling from the edge of the hopper during unloading, thus preventing material waste. It also avoids potential hazards to workers on the ground caused by falling material. Furthermore, by using a hydraulic cylinder to achieve dual control of the side door and the hopper, the overall synchronization of the device can be improved, the overall procurement cost of the device can be reduced, and the overall structure of the device can be made more compact and easier to control.

Detailed Implementation

[0023] 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.

[0024] like Figures 1-3 As shown, this embodiment provides an automatic unloading device, including:

[0025] A hopper 1 is hinged to a third shaft 6 of a base 3. The extension direction of the hopper 1 is consistent with the axial direction of the third shaft 6. A limiting plate 9 is provided on the hopper 1.

[0026] Lifting boom 4, one end of lifting boom 4 is hinged to hopper 1;

[0027] Door opening arm 7 is connected to hopper 1 via first shaft 12 and second shaft 13. First shaft 12 is hinged to hopper 1. First shaft 12, second shaft 13 and third shaft 6 are parallel to each other.

[0028] Lifting arm 5, with both ends of lifting arm 5 hinged to the other end of lifting arm 4 and door opening arm 7 respectively;

[0029] Hydraulic cylinder 2, with its two ends hinged to the base 3 and the middle of the lifting boom 4, respectively.

[0030] Overall, when it is necessary to unload the material in the hopper 1, the hydraulic cylinder 2 drives one end of the lifting arm 4 to rotate around the hopper 1. As the lifting arm 4 rotates, the lifting arm 5 drives the door opening arm 7 and the side door 8 to rotate around the first axis 12, so that the side door 8 opens until the lifting arm 4 is in contact with the limiting plate 9. At this time, the side door 8 is in a fully open state. As the hydraulic cylinder 2 continues to lift, under the limiting action of the limiting plate 9, the hopper 1 can rotate around the third axis 6 until all the material in the hopper 1 is unloaded through the opening at one end of the side door 8.

[0031] As for the hopper 1 equipped with the side door 8, when the material in the hopper 1 needs to be unloaded gradually, after a portion of the material in the hopper 1 is unloaded, the hydraulic cylinder 2 drives the lifting arm 4 to rotate, so that the bottom of the hopper 1 contacts the bottom support 31 of the base 3. After the bottom of the hopper 1 contacts the bottom support 31 of the base 3, as the hydraulic cylinder 2 continues to drive the lifting arm 4 to rotate, under the drive of the lifting arm 5, the door opening arm 7 and the side door 8 can be driven to rotate around the first axis 12, so that the side door 8 is closed. By setting the side door 8, the remaining material in the hopper 1 can be prevented from falling.

[0032] During the process of lifting the boom 4 by the hydraulic cylinder 2, the boom 4 is limited by the limiting plate 9. A single hydraulic cylinder 2 can realize the opening and closing of the side door 8 and the lifting and lowering of the hopper 1. This can maintain good synchronization between the side door 8 and the hopper 1, while also reducing the overall procurement cost of the device. In addition, the structure of a single hydraulic cylinder 2 is simpler, more compact, and easier to control.

[0033] like Figures 2-3 As shown, in this embodiment, the door opening arm 7 is provided with a recessed portion 71. When the side door 8 is in the closed state, the recessed portion 71 of the door opening arm 7 is adapted to fit the third shaft 6.

[0034] Specifically, the door opening arm 7 is provided with a recess 71. When the side door 8 is in the closed state, the recess 71 fits and conforms to the third shaft 6. Through the fitting design of the recess 71 and the third shaft 6, the overall structure of the device can be made more rational.

[0035] like Figure 1 and Figure 3 As shown, in this embodiment, when the hopper 1 is not lifted and the side door 8 is fully open, the lifting arm 4 is in contact with the limiting plate 9.

[0036] Specifically, when the hopper 1 is not lifted and the side door 8 is fully open, the lifting arm 4 is in contact with the limiting plate 9. Through the limiting support of the limiting plate 9, the hopper 1 can be driven to rotate around the third axis 6 under the lifting drive of the hydraulic cylinder 2 to achieve unloading.

[0037] like Figures 1-3 As shown, in this embodiment, when the hydraulic cylinder 2 is lifted, the side door 8 and the hopper 1 rotate clockwise around their hinge axis respectively; when the hydraulic cylinder 2 is lowered, the hopper 1 and the side door 8 rotate counterclockwise around their hinge axis respectively.

[0038] Specifically, during the lifting process of hydraulic cylinder 2, side door 8 and hopper 1 rotate clockwise around their hinge axis. When side door 8 rotates, the rotation of lifting arm 4, driven by lifting arm 5, causes door opening arm 7 and side door 8 to rotate around the first axis 12, opening side door 8. When lifting arm 4 contacts and engages with limit plate 9, hydraulic cylinder 2 continues to lift. Through the action of limit plate 9, and under the action of lifting arm 4, hopper 1 rotates around the third axis 6 until unloading is completed. After unloading is completed, the descent of hydraulic cylinder 2 causes hopper 1 and side door 8 to open. Door 8 rotates counterclockwise in sequence. When hopper 1 rotates, the rotation of the lifting arm 4, under the action of the lifting arm 5, enables hopper 1 to rotate around the third axis 6 until hopper 1 contacts the bottom support 31. After hopper 1 contacts the bottom support 31, hydraulic cylinder 2 continues to descend. Driven by hydraulic cylinder 2, lifting arm 4 rotates around hopper 1. Through the rotation of lifting arm 4, under the action of lifting arm 5, first axis 12 rotates around hopper 1. Through the rotation of first axis 12, door opening arm 7 and side door 8 can be driven to rotate, ultimately achieving the closing of side door 8.

[0039] like Figure 1As shown, in this embodiment, a recessed groove 14 is provided on the hopper 1. When the side door 8 is in the closed state, a portion of the second shaft 13 is located in the recessed groove 14.

[0040] Specifically, the hopper 1 is provided with a recessed groove 14. When the side door 8 is in the closed state, a part of the second shaft 13 is located in the recessed groove 14. The setting of the recessed groove 14 can make the overall structure of the unloading device more reasonable.

[0041] like Figures 2-3 As shown, in this embodiment, the hinge shafts of the hopper 1, the hydraulic cylinder 2, the lifting boom 4, and the lifting arm 5 are all parallel to the axial direction of the third shaft 6.

[0042] Specifically, when the hydraulic cylinder 2 drives the lifting boom 4 to rotate, the hinge shafts of the hopper 1, the hydraulic cylinder 2, the lifting boom 4, and the lifting arm 5 are all parallel to the axis of the third shaft 6. The parallelism between the hinge shafts makes the entire movement process smoother and more stable.

[0043] like Figures 1-2 As shown, in this embodiment, the hopper 1 located on the outer side wall of one end of the limiting plate 9 is provided with reinforcing ribs 11.

[0044] Specifically, the hopper 1 is equipped with reinforcing ribs 11, which can improve the overall rigidity of the hopper 1 and its overall resistance to deformation. While ensuring the rigidity of the hopper 1, it also plays a role in saving costs to a certain extent.

[0045] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.
