Description

Technical Field

[0001] This utility model relates to the field of civil engineering and construction, specifically to an earthwork transportation device. Background Technology

[0002] In civil engineering, construction sites, and road construction, earthmoving is a crucial step. Traditionally, earthmoving has relied mainly on large machinery such as loaders and excavators, but these machines have limitations in terms of flexibility, cost, and ease of operation. In recent years, with the development of miniaturization and intelligent technologies, a series of earthmoving devices have emerged on the market, aiming to improve transportation efficiency, reduce costs, and simplify operating procedures.

[0003] For example, an environmentally friendly earthmoving and transport device with patent number CN220842561U achieves the effect of cleaning the soil and mud at the bottom of the cart through a cleaning device, allowing the soil and mud at the bottom of the cart to be completely dumped out. However, this device still has shortcomings in terms of baffle operation, stability control, and wear resistance. Specifically, its baffle operation is not convenient enough, requiring additional tools or manual assistance; the hydraulic system control is not intelligent enough and cannot automatically adjust according to actual needs; in addition, the wear resistance of the inner wall of the cart is poor, which easily leads to material adhesion and affects the transport efficiency. Utility Model Content

[0004] To address the shortcomings of existing earthmoving devices in terms of baffle operation, stability control, and wear resistance, this solution proposes a novel earthmoving device, aiming to provide a convenient, stable, and wear-resistant earthmoving solution.

[0005] Specifically, the technical solution provided by this utility model is: an earthwork transportation device, comprising:

[0006] The truck bed consists of chutes, handles, grooves, limiting blocks, a load-bearing inner cavity, and an equipment cavity. The load-bearing inner cavity has a feed inlet at the top and a discharge outlet at the front. Chutes are symmetrically arranged within the truck bed frame on both sides of the discharge outlet, and a sliding baffle is installed between the chutes. During feeding, the baffle remains stationary, allowing soil and rocks to fall into the load-bearing inner cavity; during discharge, the baffle is pulled up, and the soil and rocks are discharged from the front discharge outlet. A groove is located at the rear of the truck bed, and electrically controlled support legs are installed in the groove.

[0007] The baffle has a handle integrally formed on the top, with the front of the handle protruding outside the corresponding side of the truck bed, making it convenient for users to grab the handle and pull up the baffle;

[0008] The drive shaft protection box contains a shaft seat, and a horizontally placed drive shaft is rotatably connected to the shaft seat through a bearing. Wheels are symmetrically mounted at both ends of the drive shaft. When the wheels on both sides touch the ground and rotate, they achieve synchronous movement through the drive shaft.

[0009] The support leg consists of a hydraulic cylinder, a bracket, a hydraulic push rod, a support foot, a retract button, a release button, and a protective cover. The hydraulic cylinder is fixed to the groove by a matching bracket, and the end of the hydraulic push rod is equipped with a support foot.

[0010] The main control device is located in the equipment cavity at the rear of the truck bed. The main control device consists of a PCB board with a CPU main control chip, a power supply, and auxiliary control circuits. When it is necessary to dump the soil and rocks in the truck bed, the user holds the handle to keep the device still. The main control device controls the hydraulic cylinder to extend the hydraulic push rod, and the truck bed rotates around the wheel and rises until the set extension time. Then, the user holds the handle to pull up the baffle, and the soil and rocks are discharged from the discharge cavity at the front of the truck bed.

[0011] Furthermore, protruding slide bars are machined on both sides of the baffle, and the specifications of the slide bars are adapted to the slide groove to realize the raising and lowering of the baffle.

[0012] Furthermore, a limit block is installed at the bottom of the chute. When the baffle is lowered, the limit block abuts against the baffle at its extreme position, thereby limiting the position of the baffle within the chute.

[0013] Furthermore, anti-slip grip covers are added to the handles.

[0014] Furthermore, the rear of the truck bed is equipped with a boom retraction button and a boom release button to control the hydraulic cylinder. The boom retraction button and boom release button are connected to the main control device via signal lines.

[0015] Furthermore, the retractable and extendable lever buttons are fitted with a rotatable protective cover.

[0016] Furthermore, the inner wall of the truck bed is equipped with wear-resistant liners, which are used to improve the service life of the loading bucket and reduce material adhesion.

[0017] The advantages of this utility model compared with the prior art are as follows: (1) Convenient material discharge operation: By designing a chute and slide bar structure, the baffle can be easily slid up and down. Users only need to hold the handle to easily pull up the baffle without additional tools or manpower assistance. The rear hydraulic cylinder is used to lift it, providing the earth and stone with downward tilting kinetic energy and gravitational potential energy, reducing manpower input and greatly improving operating efficiency; (2) Intelligent stability control: The main control device achieves smooth lifting and lowering of the truck bed by controlling the extension and retraction of the hydraulic cylinder. Users only need to hold the handle to keep the device still, and the main control device can automatically adjust the extension and retraction of the hydraulic cylinder according to the set extension time to ensure the stability of the truck bed during the lifting and lowering process; (3) High wear resistance design: The inner wall of the truck bed is equipped with wear-resistant liners, which effectively improves the service life of the loading bucket and reduces material adhesion. The wear-resistant liners are made of high-strength wear-resistant materials, which can resist the wear and impact of materials during the transfer process and ensure the long-term stable operation of the device.

The main control device 5 is connected to various components via signal lines to achieve coordinated control of the entire system.

[0032] Example 2

[0033] Based on Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the overall working principle of the earthwork transfer device is as follows:

[0034] (1) Loading earth and stone: The user pours earth and stone into the bearing inner cavity 105 through the feed cavity. At this time, the baffle 2 is in the lowered state, sealing the discharge cavity to prevent earth and stone leakage.

[0035] (2) Moving device: The user can move and turn the earthwork transfer device by pushing or pulling the wheels 301 on the drive shaft protection box 3, and move the device to the location where earthwork needs to be unloaded.

[0036] (3) Raise the truck bed: The user holds the handle 102 to keep the device still, and then presses the release button 406. The main control device 5 controls the hydraulic cylinder 401 to extend the hydraulic push rod 403, and the support foot 404 contacts the ground and supports the truck bed 1, so that the truck bed 1 rotates around the wheel 301 and rises to the set angle.

[0037] (4) Unloading earth and stone: The user holds the handle 201 and pulls up the baffle 2 to open the discharge port. The earth and stone are discharged from the discharge port at the front of the truck bed 1 under the action of gravity.

[0038] (5) Retracting the outriggers: After unloading, the user presses the retract button 405, and the main control device 5 controls the hydraulic cylinder 401 to retract the hydraulic push rod 403, the outriggers 404 leave the ground, and the truck bed 1 returns to its original position.

[0039] (6) Repeated operation: Users can repeat the above steps as needed to achieve continuous transportation of earth and stone.

[0040] Example 3

[0041] Based on Example 2, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working principle of the local stone transfer device is mainly based on the loading and unloading of the truck bed, the sliding control of the baffle, the hydraulic lifting of the outriggers, and the signal control of the main control device. The following is a detailed description of the working principle:

[0042] (1) Loading and unloading of the truck bed: The truck bed 1 has a loading cavity 105 for loading earth and rocks. During loading, earth and rocks fall into the loading cavity 105 through the feed inlet. At this time, the baffle 2 is in the lowered state, sealing the discharge outlet to prevent leakage of earth and rocks. During unloading, the user holds the handle 102 to keep the device stationary, and then controls the hydraulic push rod 403 of the hydraulic cylinder 401 to extend through the main control device 5, so that the truck bed 1 rotates around the wheel 301 and rises to the set angle. At this time, the user holds the handle 201 to pull up the baffle 2, and the earth and rocks are discharged from the discharge outlet at the front of the truck bed 1 under the action of gravity.

[0043] (2) Baffle sliding control: Baffle 2 is slidably connected to the slide groove 101 in the frame of the truck bed 1 via slide strips on both sides. During loading, baffle 2 naturally falls down under the action of gravity, and the slide strips slide down along the slide groove 101 until they are stopped at the limit block 104, thus fixing baffle 2. During unloading, the user holds the handle 201 and lifts baffle 2 upwards, and the slide strips slide up along the slide groove 101 until baffle 2 is fully opened, and the excavated soil and rocks are discharged from the discharge chamber.

[0044] (3) Hydraulic lifting of the support leg: The support leg 4 consists of a hydraulic cylinder 401, a bracket 402, a hydraulic push rod 403, and a support foot 404. When it is necessary to raise the truck bed 1 for unloading, the user controls the hydraulic push rod 403 of the hydraulic cylinder 401 to extend through the main control device 5, and the support foot 404 contacts the ground and supports the truck bed 1, causing the truck bed 1 to rotate around the wheel 301 and rise. After unloading is completed, the user controls the hydraulic push rod 403 to retract through the main control device 5, the support foot 404 to leave the ground, and the truck bed 1 returns to its original position.

[0045] (4) Main control device signal control: The main control device 5 is located in the equipment cavity 106 at the rear of the truck bed 1. It is responsible for receiving the user's operation commands and controlling the hydraulic lifting of the outrigger 4 and the sliding control of the baffle 2. The user sends commands to the main control device 5 by pressing the retract button 405 or the extend button 406. The main control device 5 controls the hydraulic push rod 403 of the hydraulic cylinder 401 to extend or retract according to the commands.

[0046] In practical implementation, the earthmoving and rock transport device mainly consists of components such as a truck bed 1, baffles 2, a drive shaft protection box 3, support legs 4, and a main control device 5. The truck bed 1 has an internal bearing cavity 105, with a feed inlet at the top and a discharge outlet at the front. Sliding grooves 101 are symmetrically arranged within the frame of the truck bed 1 on both sides of the discharge outlet. The baffles 2 are slidably connected to the sliding grooves 101 via sliding strips, enabling vertical sliding control. The drive shaft protection box 3 houses a drive shaft 302 and wheels 301 for the movement and steering of the device. The support legs 4 consist of hydraulic cylinders 401, brackets 402, hydraulic push rods 403, and support feet 404, used to support and raise the truck bed 1. The main control device 5 is located in the equipment cavity 106 at the rear of the truck bed 1, responsible for receiving user operating commands and controlling the operation of each component.

[0047] The baffle 2 has protruding sliding strips on both sides, and the specifications of the sliding strips are adapted to the slide groove 101. During loading, the baffle 2 naturally lowers under the action of gravity, and the sliding strips slide down along the slide groove 101 until they are stopped at the limit block 104, thus fixing the baffle 2. During unloading, the user holds the handle 201 and lifts the baffle 2 upwards, and the sliding strips slide up along the slide groove 101 until the baffle 2 is fully opened.

[0048] The support leg 4 is fixed to the groove 103 at the rear of the truck bed 1 by the bracket 402. A support foot 404 is attached to the end of the hydraulic push rod 403 of the hydraulic cylinder 401. The bottom of the support foot 404 is equipped with an anti-slip pad to ensure the support leg 4 remains stable when supporting the truck bed 1. The user sends a command to the main control device 5 by pressing the retract button 405 or the extend button 406. The main control device 5 then controls the extension or retraction of the hydraulic push rod 403 of the hydraulic cylinder 401 according to the command, thereby controlling the raising and lowering of the support leg 4.

[0049] The main control unit 5 consists of a PCB board with a CPU main control chip, a power supply, and auxiliary control circuitry. The user sends commands to the main control unit 5 by pressing the retract button 405 or the release button 406. The main control unit 5 then controls the hydraulic push rod 403 of the hydraulic cylinder 401 to extend or retract according to the commands. Simultaneously, the main control unit 5 is also responsible for receiving signals from other sensors or switches, such as the sliding state of the baffle 2, to achieve more precise control.

[0050] Operating Procedure: First, the user loads earth and rock into the load-bearing cavity 105 of the truck bed 1 through the feed inlet. Then, the user holds the handle 102 to bring the device to a standstill and uses the main control device 5 to extend the hydraulic push rod 403 of the support legs 4, causing the truck bed 1 to rotate around the wheel 301 and rise to a set angle. Next, the user holds the handle 201 to pull up the baffle 2, and the earth and rock are discharged from the discharge outlet at the front of the truck bed 1 under gravity. After unloading, the user uses the main control device 5 to retract the hydraulic push rod 403, the support legs 404 leave the ground, and the truck bed 1 returns to its original position. Finally, the user can move the device to the next work location for the next round of loading and transfer using the wheels 301 inside the drive shaft protection box 3.

[0051] In summary, the local stone transfer device, through its reasonable structural design, precise hydraulic lifting control, and convenient baffle sliding control, enables convenient loading, transfer, and unloading of earth and stone, greatly improving work efficiency and safety.
