Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, and in particular to an environmentally friendly dump truck. Background Technology

[0002] Dump trucks are specialized transport vehicles that use hydraulic or mechanical devices to tilt the cargo box and automatically unload goods. They are widely used in construction, mining, and other fields. The top cover opening and closing system of a dump truck is one of the key technologies, primarily for environmental protection, dust prevention, spill prevention, and safety compliance. Currently, most dump truck top cover opening and closing systems use hydraulic cylinders to directly drive the top cover (such as one-way or two-way cylinders). While simple in structure, this results in poor sealing and easy oil leakage. Alternatively, hydraulic power is converted into rotational or translational movement of the top cover via a hinged linkage, which optimizes the opening angle but occupies a large space. In existing technologies, some dump trucks use multi-section tarpaulins with a metal frame, operated by a winch; or the top cover slides along guide rails, saving vertical space. However, these methods significantly increase the overall width of the vehicle when the top cover is open, compressing the effective cargo space within limits and easily causing interference with the external environment. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide an environmentally friendly dump truck with a large space utilization rate, a large capacity, and good smoothness in dumping and unloading.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmentally friendly dump truck includes:

[0006] It includes a chassis and a carriage rotatably mounted on the chassis via a tilting shaft, the carriage including a body and two wing covers;

[0007] The body includes a bottom wall, two side walls, a front wall and a tail wing. The two side walls are disposed opposite to each other on the bottom wall. A first port, a second port and an upper opening opposite the bottom wall are formed between the two side walls. The front wall is disposed on the bottom wall and closes the first port. The tail wing is flipped and disposed at the other end of the two side walls so as to close or open the second port.

[0008] The two flaps are rotatably connected to the two side walls and have a closed position and an open position respectively. When both flaps are in the closed position, they cover the upper opening. When both flaps are in the open position, they are placed parallel to the outside of the two side walls respectively.

[0009] As a preferred solution for an environmentally friendly dump truck, an annular flange is provided at the edge of the upper opening, and when the flap is in the closed position, part of the outer edge of the flap abuts against the flange.

[0010] As a preferred solution for an environmentally friendly dump truck, each of the flaps is provided with a buffer post on one side, and when the flap is in the open position, the buffer post abuts against the outer surface of the side wall.

[0011] As a preferred solution for an environmentally friendly dump truck, it also includes two first driving components. Each of the two side walls is provided with a tilting seat, and each tilting seat is hinged with a connecting rod. The two connecting rods are fixed to the tail wing. Each first driving component is respectively provided on one of the side walls and drives and connects to one of the connecting rods to drive the connecting rods to rotate and cause the tail wing to tilt.

[0012] As a preferred solution for an environmentally friendly dump truck, each of the sidewalls is provided with an installation groove on its outer side, and the first drive component is located within the installation groove.

[0013] As a preferred solution for an environmentally friendly dump truck, the truck body also includes a clamping assembly. When the tail wing closes the second port, the clamping assembly can clamp or release the tail wing, and the tail wing is pressed against the ends of the two side walls and the bottom wall under the action of the clamping assembly.

[0014] As a preferred solution for an environmentally friendly dump truck, the tail wing is provided with a sealing strip. When the clamping assembly clamps the tail wing, the sealing strip seals between the tail wing and the ends of the two side walls and the bottom wall.

[0015] As a preferred solution for an environmentally friendly dump truck, the clamping assembly includes a telescopic cylinder, two grippers, and two locking pins. The telescopic cylinder has two drive ends. The two grippers are rotatably connected to the bottom wall and hinged to the two drive ends respectively. The two locking pins are located on one side of the tail wing. When the tail wing closes the second port, the telescopic cylinder drives the two grippers to rotate simultaneously and approach and clamp the two locking pins respectively, so as to drive the tail wing to press against the ends of the two side walls and the bottom wall.

[0016] As a preferred solution for an environmentally friendly dump truck, the clamping assembly is provided in multiple parts, the multiple second driving components are spaced apart on the bottom wall, and the multiple locking pins are spaced apart on one side of the tail wing.

[0017] As a preferred solution for an environmentally friendly dump truck, the locking pin is rotatably mounted on the tail wing.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model provides an environmentally friendly dump truck. The upper opening is sealed by two flaps, ensuring excellent sealing during cargo transport and preventing secondary leakage and spillage, thus avoiding secondary environmental pollution. The cargo is unloaded by tipping over the cargo box and opening the tail wing and flaps. The two opposing flaps, positioned parallel to the two side walls when open, minimize the overall shape and width of the truck, reducing space occupation and maximizing the utilization of interior space. This increases capacity and minimizes interference with the surrounding environment when the flaps are open. Furthermore, fully opened flaps completely avoid the unloaded cargo, ensuring smooth unloading. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are merely used for descriptive distinction and have no special meaning.

[0036] like Figures 1 to 8 As shown, this embodiment provides an environmentally friendly dump truck, which includes a chassis 1 and a cargo box 2 rotatably mounted on the chassis 1 via a tilting shaft. The axis of the tilting shaft is aligned with the width direction of the chassis 1, meaning that the cargo box 2 is tilted to tip over. Specifically, a lifting mechanism is also provided on the chassis 1. The lifting mechanism is driven and connected to the bottom of the cargo box 2 to lift or lower the cargo box 2. For example, the lifting mechanism includes a lifting hydraulic cylinder and a support rod. One end of the support rod is hinged to the chassis 1, and the other end is hinged to the cargo box 2. One end of the lifting hydraulic cylinder is hinged to the chassis 1, and the driving end is hinged to the cargo box 2. The extension and retraction of the lifting hydraulic cylinder drives the tilting of the cargo box 2. It should be noted that the number of lifting hydraulic cylinders and support rods is not limited here.

[0037] Specifically, the carriage 2 includes a body 21 and two flaps 22. The body 21 includes a bottom wall 211, two side walls 212, a front wall, and a rear wing 213. The two side walls 212 are arranged opposite each other on the bottom wall 211, specifically spaced apart along the width direction of the bottom wall 211. A first port, a second port, and an upper opening opposite the bottom wall 211 are formed between the two side walls 212. The front wall is set on the bottom wall 211 and closes the first port. The rear wing 213 is flipped and set at the other end of the two side walls 212 to close or open the second port. The two flaps 22 are used to close or open the upper opening. When the rear wing 213 is flipped to close the second port, an open receiving cavity is formed between the bottom wall 211, the two side walls 212, and the rear wing 213. The load is loaded into the receiving cavity. The two flaps 22 close the upper opening, thus closing the opening of the receiving cavity, so that the load is sealed in the carriage 2 for smooth transport of the load and to prevent the load from leaking. In this embodiment, the part of the carriage 2 near the tail wing 213 is rotatably connected to the base frame 1 via a flipping shaft. That is, when the tail wing 213 flips to open the second port, the carriage 2 flips, the carriage 2 tilts backward to unload the cargo, and the cargo is unloaded from the second port. At the same time, by opening the two flap covers 22, it is easier to tilt the cargo and to make the cargo completely tilted.

[0038] More specifically, the environmentally friendly dump truck also includes two first drive components 3, and each of the two side walls 212 is provided with a tipping seat 4. Each tipping seat 4 is hinged with a connecting rod 5. The hinge point between the connecting rod 5 and the tipping seat 4 is preferably located above the side wall 212. The two connecting rods 5 are fixed to the tail wing 213. Each first drive component 3 is respectively provided on one side wall 212 and drives a connecting rod 5 to rotate, thereby causing the tail wing 213 to tip. The first drive component 3 drives the tail wing 213 to tip through the connecting rod 5, so that when the tail wing 213 tipps and opens the second port, it can be completely separated from the side wall 212, which facilitates the tipping of the load. The connecting rod 5 is preferably L-shaped, having a first section and a second section that are perpendicular to each other. The end of the first section opposite to the second section is hinged to the tilting seat 4, and the second section is fixed to the tail fin 213. This provides a large contact area with the displacement, resulting in better stability and ensuring reliable operation. The first driving component 3 drives the first section and rotates the connecting rod 5 relative to the tilting seat 4, causing the tail fin 213 to tilt upwards and open the second port. The tail fin 213 is spaced apart from the side wall 212, facilitating the smooth tipping of the load. The first driving component 3 can be, but is not limited to, a hydraulic cylinder, which drives the connecting rod 5 to tilt via extension and retraction.

[0039] Preferably, such as Figure 4 As shown, each sidewall 212 has a mounting groove 10 on its outer side, and the first drive component 3 is located within the mounting groove 10. This ensures that the outer contour of the carriage 2 is relatively neat and avoids increasing the width of the carriage 2, thus ensuring that the overall vehicle dimensions do not exceed the limit and maximizing the capacity of the carriage 2.

[0040] like Figure 5 and Figure 6 As shown, to ensure the airtightness of the cavity after it is closed, the carriage 2 also includes a clamping assembly 6. When the tail wing 213 closes the second port, the clamping assembly 6 can clamp or release the tail wing 213. Under the action of the clamping assembly 6, the tail wing 213 is pressed against the ends of the two side walls 212 and the bottom wall 211. This ensures that the gap between the tail wing 213 and the ends of the side walls 212 and the bottom wall 211 is as small as possible, or even non-existent, thus ensuring the airtightness of the cavity, reducing the possibility of secondary leakage and spillage of the load, and avoiding secondary environmental pollution.

[0041] Preferably, a sealing strip is provided on the tail fin 213. When the clamping assembly 6 clamps the tail fin 213, the sealing strip seals between the tail fin 213 and the ends of the two side walls 212 and the bottom wall 211. The sealing strip further ensures the sealing performance after the second port is closed, thereby ensuring the sealing performance of the receiving cavity. For example, a U-shaped sealing strip is provided on the side of the tail fin 213 near the end of the side wall 212, corresponding to the ends of the two side walls 212 and the end of the bottom wall 211.

[0042] Specifically, the clamping assembly 6 includes a telescopic cylinder 61, two grippers 62, and two locking pins 63. The telescopic cylinder 61 is movably disposed below the bottom wall 211 and has two drive ends. The two grippers 62 are rotatably connected to the bottom wall 211 and are respectively hinged to the two drive ends. The two locking pins 63 are disposed on one side of the tail wing 213. When the tail wing 213 closes the second port, the telescopic cylinder 61 drives the two grippers 62 to rotate simultaneously and approach and clamp the two locking pins 63 respectively, so as to drive the tail wing 213 to press against the ends of the two side walls 212 and the bottom wall 211. The telescopic cylinder 61 has two drive ends, which are two coaxial telescopic rods. The telescopic cylinder 61 synchronously drives the two grippers 62 to rotate at the connection point that is rotatably connected to the bottom wall 211. The hook of the gripper 62 can rotate to hook the corresponding locking pin 63. As the gripper 62 continues to rotate, it pulls the locking pin 63 toward the end of the bottom wall 211, which drives the tail fin 213 to move closer to the bottom wall 211. The synchronous movement of the two grippers 62 enables the two grippers 62 to smoothly and accurately clamp the two locking pins 63 respectively, and makes the tail fin 213 more evenly stressed, thus stably approaching the end of the side wall 212 and the bottom wall 211.

[0043] Preferably, multiple clamping components 6 are provided, with multiple second driving members spaced apart on the bottom wall 211, and multiple locking pins 63 spaced apart on one side of the tail fin 213. For example, two clamping components 6 are provided, i.e., four grippers 62, with each pair of grippers 62 moving synchronously. The two clamping components 6 are respectively close to opposite sides of the tail fin 213, so that the tail fin 213 is subjected to uniform force and can stably and efficiently approach the ends of the side wall 212 and the bottom wall 211, avoiding gaps between the side of the tail fin 213 and the side wall 212, and saving the need to provide clamping components 6 on the side wall 212. Of course, in other embodiments, clamping components 6 can also be provided between the side wall 212 and the tail wall to further ensure sealing.

[0044] More preferably, the locking pin 63 is rotatably mounted on the tail fin 213, which reduces the friction when the pawl 62 pulls the locking pin 63 after hooking it, improves the smoothness of pulling, and helps save power.

[0045] like Figure 7 and Figure 8As shown, further, the two flaps 22 are rotatably connected to the two side walls 212 respectively, and each has a closed position and an open position. When both flaps 22 are in the closed position, the upper end of the flap is open. When both flaps 22 are in the open position, they are placed parallel to the outside of the two side walls 212 respectively. It should be noted that the plane parallel to the side of the flap 22 is parallel or approximately parallel to the plane of the side wall 212. By sealing the upper opening with two flaps 22, the cargo compartment 2 achieves better sealing when transporting loads, reducing the risk of secondary leakage and spillage, and preventing secondary environmental pollution. The two opposing flaps 22, positioned parallel to the two side walls 212 when open, minimize the overall shape and width variation of the environmentally friendly dump truck, reducing its space occupation and ensuring its registration. This maximizes the utilization of the interior space of the cargo compartment 2, increasing its capacity. Furthermore, the flaps 22, when open, do not interfere with the surrounding environment, and when fully open, they completely avoid the dumped load, ensuring smooth unloading.

[0046] Preferably, an annular flange 23 is provided at the edge of the upper opening. When the flap 22 is in the closed position, part of the outer edge of the flap abuts against the flange. That is, the annular flange 23 is provided along the upper inner edge of the side wall 212, the front wall, and the tail fin 213 in the closed state. When the flap 22 is in the closed position, the annular flange 23 provides support for the flap 22 and also plays a sealing role. This can effectively prevent the flap 22 from deforming after long-term use, and also make the sealed cavity well sealed, avoiding secondary dripping and spillage, thereby avoiding environmental pollution.

[0047] Specifically, each sidewall 212 has a mounting base 7 and a second driving member at its two ends at the upper end. Each mounting base 7 has a flip rod 8 rotatably mounted on it via a pivot. The flip rod 8 is fixed to one side of the flap 22, and is fixed to the flap 22 when it is in the closed position. Each second driving member drives the pivot to rotate, thereby causing the flip rod 8 and the flap 22 to flip. The second driving member can be, but is not limited to, a hydraulic motor.

[0048] In this embodiment, the flipping lever 8 includes a crank portion 81 and a straight portion 82 set at an angle, preferably at an obtuse angle, and is shaped like a "golf club". The crank portion 81 is rotatably connected to the mounting base 7, and the straight portion 82 is fixedly connected to the flap cover 22, so that when the flap cover 22 is flipped to the closed position, it can seal against the annular flange 23, and when it is flipped to the open position, it is parallel or approximately parallel to the side wall 212.

[0049] Preferably, each flap 22 has a buffer post on one side. When the flap 22 is in the open position, the buffer post abuts against the outer surface of the side wall 212 to prevent the flap 22 from colliding and rubbing against the side wall 212 when it is open, thus preventing paint peeling or deformation. The buffer post may be, but is not limited to, a rubber post.

[0050] The design of the wing cover 22 of this environmentally friendly dump truck makes the change in the overall size of the vehicle small when the wing cover 22 is opened. Within the upper limit of dump truck size, the space utilization rate is large, resulting in a larger overall loading capacity. Compared with traditional dump trucks, the space utilization rate is increased by 15%. In addition, the environmentally friendly dump truck has better sealing performance, which effectively avoids secondary dripping and spillage and avoids secondary pollution of the environment.

[0051] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
