Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a concrete material cart. Background Technology

[0002] In the construction process, the transportation and temporary transfer of concrete are crucial to ensuring construction progress and quality. Traditional concrete transportation mainly relies on mixer trucks to transport mixed concrete from the batching plant to the construction site, where it is then poured manually or using simple tools. While this method achieves on-site concrete supply to some extent, it still has many inconveniences and shortcomings.

[0003] First, traditional concrete storage methods lack flexibility and mobility, hindering the rapid distribution and on-demand use of concrete within the construction area. This can easily increase construction waiting time, thereby affecting overall construction efficiency. Second, because concrete has a limited initial setting time, if the transportation and on-site waiting time is too long, the concrete is prone to segregation or premature setting, leading to material waste and even affecting the construction quality and safety of subsequent structures.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0009] The material guiding assembly includes an outlet on the main body and a material guiding trough below the outlet. The outlet has a groove, and a hinged baffle is provided in the groove. The flow rate of concrete is controlled by rotating the baffle.

[0010] Furthermore, the material guiding assembly also includes a connecting block disposed between the vehicle frame and the material guiding trough. The connecting block includes two parallel connecting parts and a second rotating shaft. One end of the material guiding trough is disposed between the two connecting parts and connected by the second rotating shaft. The material guiding trough rotates along the second rotating shaft.

[0011] Furthermore, the baffle has a first protrusion on its side and a second protrusion on the outlet pipe. A first rotating shaft is provided between the first protrusion and the second protrusion, and the baffle rotates along the first rotating shaft.

[0012] Furthermore, the guide trough includes a first connecting section and a second connecting section, and each of the opposite ends of the first connecting section and the second connecting section is provided with a hanging ear. A third rotating shaft is provided inside the hanging ear, and the second connecting section rotates along the third rotating shaft.

[0013] Furthermore, the main body is provided with a transparent cover.

[0014] Furthermore, an opening assembly is provided between the cover and the body;

[0015] The opening assembly includes a rotating component with one end disposed on the cover and a fixing component disposed on the side of the main body. The rotating component and the fixing component are connected by a fourth rotating shaft. The rotating component rotates along the fourth rotating shaft, thereby opening or closing the cover.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication 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.

[0033] like Figures 1 to 6 As shown: A concrete material trolley includes: a trolley body 1, connectors 2 and a material guiding assembly 3 respectively disposed at both ends of the trolley body 1, the connectors 2 being used to connect to an excavator, and the material guiding assembly 3 being used to control the flow of concrete.

[0034] The vehicle body 1 includes, from top to bottom, a main body 11, a frame 12, and a universal wheel 13. The main body 11 is connected to the frame 12 at one end by a pivot. A power component 4 is provided between the main body 11 and the frame 12 to lift one end of the main body 11 and tilt the main body 11.

[0035] The material guiding assembly 3 includes an outlet 31 disposed on the body 11 and a material guiding trough 32 disposed below the outlet 31. The outlet 31 is provided with a groove 311, and a hinged baffle 312 is provided in the groove 311. The flow rate of concrete is controlled by rotating the baffle 312.

[0036] When using, such as Figure 1 As shown, the excavator is connected to the field equipment, such as an excavator, via the connector 2. The material trolley is driven to the construction site. At the higher work station, the excavator's grab handle digs out concrete from the body 11. At the lower work station, the power unit 4 is activated to control the body 11 to rotate at an angle along the shaft. The body and the guide chute 32 are tilted to allow the concrete to be introduced into the lower construction section.

[0037] Traditional concrete transfer equipment is often stationary or requires manual transport. This solution introduces a vehicle body structure + universal wheels design, which gives the material vehicle good mobility and can quickly adapt to different construction sections and be flexibly scheduled and used.

[0038] By linking with the excavator through the connector 2, concrete can be grabbed and transported from the high-level working face; by controlling the tilt of the main body 11 through the power component 4, the concrete is guided to the lower level by gravity, avoiding the repetitive operation and manpower waste caused by transporting the concrete to the high and low levels separately.

[0039] The on-site small-batch delivery and "use-as-you-go" mode shortens the waiting time of concrete on site, reduces risks such as segregation and initial setting, and ensures concrete performance; the combined design of the guide chute 32 and adjustable baffle 312 effectively controls the concrete flow rate and improves the uniformity of pouring and operational safety.

[0040] No need for repeated manual loading and unloading of concrete; the movement and unloading operations are completed with mechanical assistance, which greatly reduces the intensity and safety risks of manual handling. It is especially suitable for complex construction environments or scenarios with large terrain differences.

[0041] Among them, the power component 4 can be a hydraulic cylinder. The hydraulic cylinder has strong load-bearing capacity and can stably lift the body 11 after it is loaded with concrete. Even in the case of large volume or high density materials, it can still maintain reliable operation and adapt to the heavy load conditions on the construction site. As a power component 4, the hydraulic cylinder has the advantages of stable output, controllable thrust and smooth operation, which makes the angle adjustment of the body 11 during the tilting process smoother and avoids concrete splashing or uncontrolled pouring due to uneven tilting or excessive speed.

[0042] As a preferred embodiment of the above, such as Figure 2 , 3 As shown, the material guiding assembly 3 also includes a connecting block 33 disposed between the vehicle frame 12 and the material guiding trough 32. The connecting block 33 includes two parallel connecting parts 331 and a second rotating shaft 332. One end of the material guiding trough 32 is disposed between the two connecting parts 331 and connected by the second rotating shaft 332. The material guiding trough 32 rotates along the second rotating shaft 332. On the one hand, the discharge direction can be flexibly adjusted according to the actual needs of the construction site, and the concrete drop position can be precisely controlled to adapt to different pouring positions and spatial environments, thereby improving on-site operation efficiency. On the other hand, the rotatable structure allows the material guiding trough 32 to be rotated to the side or bottom of the vehicle body 1 for folding and storage when not in operation, reducing the overall space occupied and facilitating the transportation of construction equipment and the storage and management of the trolley.

[0043] In this embodiment, refer to Figure 3 The baffle 312 has a first protrusion 312a on its side and a second protrusion 313 on the pipe of the outlet 31. A first rotating shaft 314 is provided between the first protrusion 312a and the second protrusion 313. The baffle 312 rotates along the first rotating shaft 314, so that the baffle 312 can maintain smooth rotation and not jam during opening or closing, thereby improving the reliability and durability of the baffle 312 control.

[0044] The material guide trough 32 includes a first connecting section 321 and a second connecting section 322. Each of the opposite ends of the first connecting section 321 and the second connecting section 322 is provided with a hanging ear 323. A third rotating shaft 324 is provided inside the hanging ear 323. The second connecting section 322 rotates along the third rotating shaft 324. Specifically, the second connecting section 322 can be folded along the third rotating shaft 324 above the first connecting section 321. When not in use, the material guide trough 32 can be shortened to reduce the overall length and space occupation, which facilitates the layout of equipment on the construction site and the transfer and storage of trolleys.

[0045] In this embodiment, as Figure 4 As shown, the main body 11 is equipped with a transparent cover 5. On the one hand, the cover 5 is made of transparent material, allowing operators to directly observe the state and remaining amount of concrete inside the vehicle body 1 without having to frequently open the cover or use tools to check, thus improving work efficiency and reducing the risk of misoperation. On the other hand, during concrete transportation or waiting, the cover 5 can effectively cover the opening of the vehicle body 1 to prevent materials from splashing due to bumps or wind, while also preventing external impurities from falling into the concrete, ensuring the quality of construction materials and the cleanliness of the construction site.

[0046] As a preferred embodiment of the above, such as Figure 5 , 6 As shown, an opening assembly 6 is provided between the cover 5 and the body 11;

[0047] The cover opening assembly 6 includes a rotating component 61 with one end mounted on the cover 5 and a fixing component 62 mounted on the side of the main body 11. The rotating component 61 and the fixing component 62 are connected by a fourth rotating shaft 63. The rotating component 61 rotates along the fourth rotating shaft 63, causing the cover 5 to open or close. Specifically, the cover 5 is opened and closed by rotating the rotating component 61 along the fourth rotating shaft 63, eliminating the need to disassemble or completely remove the cover 5, simplifying the operation and improving efficiency. At the same time, the rotating connection structure ensures that the cover 5 is not easily detached during transportation, tipping, or vibration, enhancing the overall reliability and safety of the device and improving its adaptability to harsh environments.

[0048] The rotating component 61 has two symmetrical columnar structures 611 at the end near the fixed component 62, and the fixed component 62 has a pin 621 at the end away from the rotating component 61. The columnar structures 611 and the pin 621 are fitted with springs 64. After the rotating component 61 rotates, the columnar structures 611 abut against the fixed component 62 to limit the opening angle of the cover 5. The spring 64 provides elastic assistance during the opening or closing of the cover 5, which can buffer resistance when opening and provide assistance when closing, effectively reducing the force required by the operator and improving the convenience and comfort of operation. During the closing of the cover 5, the spring 64 plays a buffering and energy-absorbing role, preventing the cover 5 from violently impacting the edge of the vehicle body 1 due to gravity, preventing damage and material fatigue, and improving service life.

[0049] As a preferred embodiment of the above, the connector 2 includes an annular component 21 connected to the excavator and an L-shaped hook 22 disposed on the frame 12. The L-shaped hook 22 is inserted into the annular component 21, and a plug-in locking relationship is formed between the annular component 21 and the L-shaped hook 22, which effectively prevents the component from falling off or loosening due to vibration or uneven loading during transportation or operation, and enhances the stability and safety of the overall connection. The plug-in structure is easier to connect and disassemble quickly, which facilitates flexible loading and unloading at the construction site and shortens the equipment switching and maintenance time.

[0050] In this embodiment, a ramp 111 is provided at the bottom of the vehicle body 1 near the outlet 31. When the vehicle body 1 is in a horizontal state, it can also guide concrete to flow into one side of the outlet 31. In the initial state, it reduces the dependence on the action of the power component 4, and can complete part of the material discharge without tilting the vehicle body 1, thereby improving work efficiency and flexibility.

[0051] The baffle 312 is radially provided with a handle 312b, and a small ball 312c is provided at the end of the handle 312b. This increases the gripping area, improves operating comfort, reduces fatigue caused by long-term operation, and allows the operator to directly adjust the position of the baffle 312 manually, thereby conveniently and quickly controlling the discharge flow rate of concrete and improving the controllability and accuracy of the discharge.
