Description

Technical Field

[0001] This utility model relates to the field of dump truck equipment technology, and more specifically, to a dump truck. Background Technology

[0002] Dump trucks, a common type of short-distance material transport equipment, typically consist of a chassis and a hopper. The hopper is rotatably mounted on the chassis and is driven by hydraulic cylinders or other power components to tip and unload materials. They are suitable for transporting various bulk materials such as sand, gravel, earth, coal, and ore, and are characterized by strong power and flexible operation. They are widely used in various small construction sites and home work environments.

[0003] However, due to structural design and cost control, the hoppers of commonly used small dump trucks can generally only tilt and dump in place around a fixed axis, making it difficult to effectively increase the overall unloading height. This limitation means that they often cannot meet the needs of applications requiring the transportation and dumping of materials from a low position to a higher receiving position (such as unloading into a higher silo, stack, or truck bed), thus greatly restricting their applicability.

[0004] Furthermore, existing small dump trucks typically require operators to manually shovel materials into the hopper using tools such as shovels during loading operations. This method is not only labor-intensive and inefficient, but also prone to operator fatigue when handling large quantities of materials, affecting overall work progress and work experience.

[0005] Therefore, it is necessary to improve the existing dump truck structure to solve the above problems. Utility Model Content

[0006] To overcome at least one of the defects in the prior art, this utility model aims to provide a dump truck that can adjust the height of the hopper and eliminates the need for manual shoveling, so as to be suitable for more application scenarios and improve logistics and transportation efficiency.

[0007] This utility model provides a tipper truck: including a frame, a driving unit for driving the frame to move, and a hopper. The frame is provided with a lifting assembly, the hopper is rotatably mounted on the lifting assembly, and the lifting assembly is provided with a first driving cylinder for driving the hopper to rotat. It also includes a shovel bucket, which is rotatably connected to the hopper. The shovel bucket is provided with a second driving cylinder, which is used to drive the shovel bucket to rotat so as to dump material into the hopper.

[0008] Compared with the prior art, the dump truck of this utility model has the following advantages: In this utility model's tipper truck structure, an upgraded component is installed on the frame, and the hopper is mounted on a lifting component to achieve height adjustment, thus better adapting to application scenarios where materials are transported from a low position and dumped to a higher receiving position. Furthermore, the hopper is rotatably connected to the lifting component, and a first drive cylinder is also provided on the lifting component to drive the hopper to automatically tilt and discharge material. More importantly, a tiltable bucket and a second drive cylinder are also provided on the hopper. When shoveling material, the bucket is tilted downwards to be level with the ground, the traveling unit moves forward to shovel material from the ground into the bucket, and then the second drive cylinder drives the bucket to tilt upwards, slowly tilting it backwards until the material in the bucket automatically slides into the hopper, replacing the traditional manual shoveling action, saving labor and improving transportation efficiency.

[0009] As an improvement, the bucket is connected to two support arms on both sides, and the ends of the two support arms away from the bucket are respectively rotatably connected to the two sides of the bucket. The two sides of the bucket are provided with second drive cylinders for driving the two support arms to rotate respectively.

The two second rotating arms are located inside the two first rotating arms, and one end of each of the two second rotating arms is hinged to the vehicle frame, and the other end is hinged to one end of the connecting seat. The hopper is rotatably connected to the other end of the connecting seat. The first drive cylinder is connected between the connecting seat and the bucket. The third drive cylinder is used to drive the two first rotating arms to lift and lower.

[0011] In a further improvement, a reinforcing plate is connected to the bottom of the hopper, and two fixed ribs are connected to the reinforcing plate. One end of the first drive cylinder is hinged between the two fixed ribs, and the other end is hinged to the connecting seat.

[0012] In a further improvement, a positioning shaft is connected between the middle of the two first rotating arms, one end of the third drive cylinder is hinged to the vehicle frame, and the other end is rotatably connected to the positioning shaft.

[0013] Furthermore, the vehicle frame includes a base, the walking unit is connected to the lower end of the base, the rear end of the base is provided with a mounting bracket, the front side wall of the mounting bracket is provided with a vertically extending mounting rib, one end of each of the two first rotating arms is hinged to the upper end of the mounting rib, one end of each of the two second rotating arms is hinged to the middle of the mounting rib, and one end of the third drive cylinder is hinged to the lower end of the mounting rib.

[0014] In a further improvement, a fixing plate is connected between the two ends of the first rotating arms that are close to the mounting rib.

[0015] In a further improvement, the mounting bracket is equipped with an operating box, which contains control valve groups for controlling the extension and retraction of each drive cylinder.

[0021] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0022] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See Figures 1-5 As shown in the figure, this application discloses a tipper truck, including a frame 1, a traveling unit 2 for driving the frame 1 to move, and a hopper 3. The frame 1 is provided with a lifting component 4, and the hopper 3 is rotatably mounted on the lifting component 4. The lifting component 4 is provided with a first drive cylinder 5 for driving the hopper 3 to rotate. In this structure, the height of the hopper 3 can be adjusted by the lifting component 4, so as to be suitable for application scenarios of transporting materials from a low position and dumping them to a higher receiving position. Furthermore, the lifting component 4 is also provided with a first drive cylinder 5 for driving the hopper 3 to automatically rotate and unload materials. The structure is simple and the drive is convenient.

[0025] Additionally, the tipper truck of this application also includes a bucket 6, which is tumbled and connected to the hopper 3. The hopper 3 is equipped with a second drive cylinder 7, which drives the bucket 6 to tilt and dump the material scooped from the ground into the hopper 3. Specifically, during shoveling, the bucket 6 is tilted downwards to be level with the ground, the traveling unit 2 moves forward to scoop the material from the ground into the bucket 6, and then the second drive cylinder 7 drives the bucket 6 to tilt upwards. The bucket 6 slowly tilts backwards until the material in the bucket 6 automatically slides into the hopper 3. The bucket 6 replaces the traditional manual shoveling action, saving labor and improving transportation efficiency.

[0026] In this embodiment, support arms 8 are connected to both sides of the bucket 6. The ends of the two support arms 8 away from the bucket 6 are rotatably connected to both sides of the hopper 3, and the two sides of the hopper 3 are provided with second drive cylinders 7 for driving the two support arms 8 to rotate respectively. The power is more stable by synchronous driving of the two second drive cylinders 7.

[0027] On another note, the lifting assembly 4 in this embodiment includes two first rotating arms 401, two second rotating arms 402, a connecting seat 403, and a third drive cylinder 404. One end of each of the two first rotating arms 401 is hinged to the frame 1, and the other end is hinged to the middle of the connecting seat 403. The two second rotating arms 402 are located inside the two first rotating arms 401, and one end of each of the two second rotating arms 402 is hinged to the frame 1, and the other end is hinged to the lower end of the connecting seat 403. The hopper 3 is rotatably connected to the connecting seat 403. At the upper end, the first drive cylinder 5 is connected between the connecting seat 403 and the bucket 6, and the third drive cylinder 404 is used to drive the two first rotating arms 401 to lift and lower. In this structure, while the two first rotating arms 401 are lifted, the two second rotating arms 402 are lifted synchronously, thereby driving the connecting seat 403 and the bucket 3 to move upward smoothly. When the material in the bucket 3 needs to be unloaded, the first drive cylinder extends and drives the bucket 3 to tilt forward until the material in the bucket 3 automatically slides down, realizing the automatic discharge of the bucket 3.

[0028] In addition, in this embodiment, in order to strengthen the structural strength of the hopper 3 at the tipping connection, a reinforcing plate 9 is connected to the bottom of the hopper 3. Two fixed ribs 10 are connected to the reinforcing plate 9. One end of the first drive cylinder 5 is hinged between the two fixed ribs 10, and the other end is hinged to the connecting seat 403. In this structure, the two ends of the reinforcing plate 9 extend to the corners of the front side plate and the bottom plate of the hopper 3 and the corners of the bottom plate and the rear side plate, respectively, which effectively improves the structural strength of the bottom of the hopper 3 and prevents the bottom plate from bending and deforming when tipping over to unload.

[0029] More specifically, in the above structure, a horizontally arranged positioning shaft 11 is connected between the middle of the two first rotating arms 401. The lower end of the third drive cylinder 404 is hinged to the frame 1, and the upper end is rotatably connected to the positioning shaft 11. That is, the hopper 3 is smoothly lifted by the extension and retraction of the third drive cylinder 404.

[0030] In this embodiment, the frame 1 includes a base 101, and the walking unit 2 is connected to the lower end of the base 101. The rear end of the base 101 is provided with a mounting bracket 102. The mounting bracket 102 is vertically arranged and slightly tilted backward, that is, the entire frame 1 is roughly L-shaped. There are two vertically extending mounting ribs 103 on the front side wall of the mounting bracket 102. The mounting ribs 103 are arranged at a designed interval. One end of the two first rotating arms 401 is hinged to the two sides of the upper end of the two mounting ribs 103 through a hinge shaft. One end of the two second rotating arms 402 is hinged to the two sides of the middle position of the two mounting ribs 103 through a hinge shaft. One end of the third drive cylinder 404 is hinged between the lower ends of the two mounting ribs 103 through a hinge shaft. In this structure, the first rotating arm 401 and the second rotating arm 402 are also roughly L-shaped. The outer ends of the vertical parts of the first rotating arm 401 and the second rotating arm 402 are hinged to the mounting rib 103. The outer ends of the horizontal parts of the first rotating arm 401 are slightly inclined upwards and are hinged to the two sides of the middle part of the connecting seat 403. The outer ends of the horizontal parts of the second rotating arm 402 are slightly inclined downwards and are hinged to the two sides of the lower end of the connecting seat 403. In the initial state of the hopper 3, the vertical parts of the two first rotating arms 401 and the second rotating arm 402 are close to the front side wall of the mounting frame 102, and the horizontal parts of the two first rotating arms 401 and the second rotating arm 402 are basically level with the base 101. At this time, the hopper 3 is horizontal.

[0031] In the above structure, a fixing plate 12 is connected between the two first rotating arms 401 at one end (vertical part) near the mounting rib plate 103, which can ensure that the two first rotating arms 401 can rise and fall synchronously and smoothly under the action of the third drive cylinder 404.

[0032] In addition, in this embodiment, an operation box 13 is provided at the rear of the mounting frame 102. The operation box 13 is provided with a control valve group for controlling the extension and retraction of each drive cylinder. The upper part of the operation box 13 is provided with an operation handle 14 that is connected to the control valve group. That is, by operating the corresponding operation handle 14, the lifting and tilting of the hopper 3 and the tilting of the bucket 6 can be realized, which is very convenient.

[0033] More specifically, a tiltable support platform 15 is provided at the rear end of the base 101, and a handrail 16 is provided at the top of the control box 13. The support platform 15 is for the operator to stand on, allowing for easy operation. In addition, the handrail 16 is for the operator to grip, ensuring the operator's safety during the movement of the frame 1.

[0034] In this embodiment, the walking unit 2 includes a walking track 201 installed at the bottom of the frame 1 and a power device for driving the walking track 201. The power device here is a power system composed of an engine, a clutch and a gearbox. The upper end of the control box 13 is also provided with a control button for controlling the start and stop of the power device. Similarly, the operator can control the walking of the frame 1 by standing on the support platform 15, which is very convenient.

[0035] In this embodiment, the first drive cylinder 5, the second drive cylinder 7, and the third drive cylinder 404 are all hydraulic cylinders, and a hydraulic station (not shown in the figure) for providing hydraulic pressure to each hydraulic cylinder is also provided on the frame 1.
