Description

A mobile cross-concrete conveying device Technical Field

[0001] This utility model relates to the field of concrete conveying technology, specifically a mobile, cross-concrete conveying device. Background Technology

[0002] With the continuous improvement of rural water conservancy infrastructure, some rural branch canals, due to their age, have seen their embankments gradually raised over time. The embankments, the dikes on both sides of the canal, are the civil engineering structures that support and reinforce the canal, preventing water overflow and protecting its stability. The gradual raising of the embankments has resulted in the current top surface of the embankment being higher than the original road surface of the canal top, creating a height difference that poses a challenge to further raising the embankments. Simultaneously, the road surface on one side of the canal is relatively wide, approximately 2 meters, serving as a farm vehicle for villagers to access their fields, but it cannot accommodate heavy vehicles such as concrete mixer trucks. The road surface on the other side of the canal is narrower, allowing only one person to pass at a time. This structural characteristic means that concrete mixer trucks can only stop at the canal entrance road.

[0003] To raise the embankment along the narrow side of the canal, two main methods are currently used for concrete transportation: one is to use an HBT60 concrete pump for pumping. First, the concrete is transported from the concrete mixer truck to the concrete pump using a farm tricycle, and then the pumping stage begins. During the pumping stage, the position of the concrete pump needs to be moved multiple times. The other method is to transport the concrete manually by carrying it across a temporary bridge.

[0004] However, practice has shown that raising the embankment along the narrow side of the canal using existing concrete delivery methods presents the following problems: First, when using an HBT60 concrete pump for pumping, the pump needs to be moved multiple times during the pumping process, requiring workers to disassemble and reassemble the pump pipe. This not only results in a long preparation time before construction but also makes the pump pipe prone to blockage due to changes in external conditions or improper operation during construction. Dealing with the blockage is not only time-consuming and labor-intensive but also greatly reduces construction efficiency, thus affecting the construction progress. Second, manually carrying concrete across temporary bridges not only results in small volumes of concrete transported each time, leading to low efficiency, but also poses significant safety hazards, especially during spring irrigation when the water depth can reach 2 meters, making the situation even more dangerous.

[0005] Therefore, it is necessary to invent a mobile concrete conveying device to solve the above problems. Summary of the Invention

[0006] In order to solve the problems of low construction efficiency, inconvenient equipment movement, and great safety hazards when raising the embankment next to the narrow side of the canal top road using existing concrete conveying methods, this utility model provides a mobile concrete conveying device that can cross the canal top.

[0007] This utility model is achieved using the following technical solution:

[0008] A mobile concrete conveying device includes a base, an engine and a screw conveyor mounted on the upper surface of the base, a drive pulley mounted on the output end of the engine, and multiple main travel wheels mounted on the lower surface of the base.

[0009] The screw conveyor includes a trough, which includes a bottom plate. Two side plates are provided on the upper surface of the bottom plate. A front plate and a rear plate are fixed between the two side plates. An installation hole is provided on the rear plate. A screw shaft is rotatably connected inside the trough and between the front plate and the rear plate. A screw blade is fixed on the outer surface of the screw shaft. A driven pulley is installed at the front end of the screw shaft. The driven pulley is located outside the trough and is connected to the driving pulley by a belt drive. A feed hopper is installed at the top of the front end of the trough and is connected to the trough. An auxiliary traveling wheel is installed at the front of the lower surface of the bottom plate. A support column is installed at the rear of the lower surface of the bottom plate. A discharge port is provided at the rear of the lower surface of the bottom plate. A discharge adjustment mechanism is installed at the rear end of the trough.

[0010] The unloading adjustment mechanism includes an L-shaped adjustment plate that is slidably connected to the inner side of the trough. A horizontal screw is fixed to the side of the vertical plate of the adjustment plate. The horizontal screw passes through the mounting hole and is mounted on the rear end plate of the trough. The bottom plate of the adjustment plate is adapted to the discharge port on the bottom plate.

[0011] Furthermore, both the base plate and the base plate of the adjusting plate are U-shaped.

[0012] Furthermore, lifting handles are provided at the rear ends of the two side plates of the trough.

[0013] Furthermore, the engine is a gasoline engine.

[0014] Furthermore, a push handle is provided at the rear end of the base.

[0015] Furthermore, the diameter of the driving pulley is smaller than the diameter of the driven pulley.

[0016] Furthermore, the number of main traveling wheels is two, the number of auxiliary traveling wheels is one, and the bottom of the auxiliary traveling wheel is higher than the bottom of the main traveling wheel.

[0017] Furthermore, the end of the horizontal screw is provided with two nuts, one nut located inside the rear end plate of the groove and the other nut located outside the rear end plate of the groove.

[0018] This utility model features a reasonable and reliable structural design. It utilizes a gasoline engine as its power source, driving the screw shaft via belt transmission to achieve continuous concrete conveying. This solves the problems of insufficient power supply and the inconvenience of moving traditional pumping equipment at rural construction sites. Simultaneously, the screw conveyor employs a screw shaft and screw blade design, making concrete flow smoother, reducing resistance and the risk of blockage, and improving conveying efficiency. Furthermore, the combination of the main and auxiliary traveling wheels forms a stable three-point support structure, facilitating the device's movement across uneven canal embankments and enhancing its terrain adaptability. In addition, the unloading adjustment mechanism can adjust the size of the discharge port according to actual pouring needs, controlling the concrete flow rate and enhancing construction flexibility. This utility model has a simple overall structure, low cost, and is easy to promote and use. It effectively replaces existing manual carrying or concrete pumping methods, significantly improving construction efficiency, reducing safety risks and construction costs, and has good application prospects and socio-economic benefits.

[0025] A mobile concrete conveying device, as shown in Figures 1 to 5, includes a base 1, an engine 2 and a screw conveyor mounted on the upper surface of the base 1, a drive pulley 3 mounted on the output end of the engine 2, and multiple main travel wheels 4 mounted on the lower surface of the base 1.

[0026] The screw conveyor includes a trough 5, which includes a bottom plate 6. Two side plates 7 are provided on the upper surface of the bottom plate 6. A front plate 8 and a rear plate 9 are fixed between the two side plates 7. The rear plate 9 has a mounting hole. A screw shaft 10 is rotatably connected inside the trough 5 between the front plate 8 and the rear plate 9. A screw blade 11 is fixed on the outer surface of the screw shaft 10. A driven pulley 12 is installed at the front end of the screw shaft 10. The driven pulley 12 is located outside the trough 5 and is connected to the driving pulley 3 by a belt drive. A feed hopper 13 is installed at the top of the front end of the trough 5 and is connected to the trough 5. An auxiliary traveling wheel 14 is installed at the front of the lower surface of the bottom plate 6. A support column 15 is installed at the rear of the lower surface of the bottom plate 6. A discharge port is opened at the rear of the lower surface of the bottom plate 6. A discharge adjustment mechanism is installed at the rear end of the trough 5.

[0027] The unloading adjustment mechanism includes an L-shaped adjustment plate 16, which is slidably connected to the inner side of the tank 5. A horizontal screw 17 is fixed to the side of the vertical plate of the adjustment plate 16. The horizontal screw 17 passes through the mounting hole and is installed on the rear end plate 9 of the tank 5. The bottom plate of the adjustment plate 16 is adapted to the discharge port on the bottom plate 6.

[0028] The engine 2 is a gasoline engine.

[0029] The diameter of the driving pulley 3 is smaller than the diameter of the driven pulley 12.

[0030] The horizontal screw 17 has two nuts 20 at its end. One nut 20 is located inside the rear end plate 9 of the groove 5, and the other nut 20 is located outside the rear end plate 9 of the groove 5.

[0031] In this invention, the engine 2, drive pulley 3, belt, and driven pulley 12 constitute a power transmission system. The power of the engine 2 is transmitted to the screw shaft 10 via the belt. The design of the drive pulley 3 having a smaller diameter than the driven pulley 12 achieves speed reduction and torque increase, allowing the screw shaft 10 to obtain greater torque and improve conveying efficiency. At the same time, the gasoline engine starts quickly, has low fuel consumption, and low operating costs. Combined with the screw conveyor, it achieves independent operation capability, solving the shortcomings of existing concrete conveying pumps that rely on external power or complex hydraulic systems, and improving the applicability of this device in environments without electricity. The screw shaft 10 and screw blades 11 are the core conveying components. By rotating, they push the concrete forward, realizing the continuous conveying of concrete across channels, replacing existing concrete conveying pumps or manual carrying methods, improving construction efficiency, avoiding the dangers of manual transportation, and greatly reducing concrete blockage problems. The combined structure design of the adjusting plate 16, horizontal screw 17, and nut 20 allows for sliding adjustment of the discharge port size, controlling the amount of concrete discharged per unit time, and is suitable for the needs of channel embankment pouring with different cross-sectional dimensions, improving the flexibility of this device.

[0032] The rear end of the base 1 is provided with a push handle 19.

[0033] The number of main travel wheels 4 is two, the number of auxiliary travel wheels 14 is one, and the bottom of the auxiliary travel wheel 14 is higher than the bottom of the main travel wheel 4.

[0034] The main traveling wheel 4 and the auxiliary traveling wheel 14 form a three-point traveling structure, which not only makes the device easy to move, but also ensures the stability of the device's movement, solving the problem of frequent disassembly and assembly required by existing concrete conveying pumps.

[0035] Both the base plate 6 and the base plate of the adjusting plate 16 are U-shaped.

[0036] The U-shaped structure design facilitates concrete flow, reduces resistance, and improves conveying efficiency.

[0037] The two side plates 7 of the trough 5 are provided with lifting handles 18 at their rear ends.

[0038] The structural design of the lifting handle 18 facilitates the movement and position adjustment of this device, further improving its flexibility.

[0039] In use, as shown in Figure 1, a channel 21 is set up at the construction site. One side of the channel 21 is a wide channel road 22, and the other side is a narrow channel road. A first channel embankment 23 is set on the wide channel road 22, and a second channel embankment 24 is set on the narrow channel road. A channel embankment template 25 is erected on the top surface of the second channel embankment 24. First, the device is pushed from the channel opening to the vicinity of the construction section via the main traveling wheel 4 across the wide channel road 22. The screw conveyor is straddling the channel 21. Construction workers on the narrow channel road manually lift the rear end of the trough 5 by lifting the handrail 18, so that the auxiliary traveling wheel 14 is placed on the upper surface of the first channel embankment 23, and the support column 15 is placed at the support position on the channel embankment template 25 and connected and fixed. After the connection is stable, the engine 2 is started, so that the driving pulley 3 drives the driven pulley 12 to rotate via the belt, which in turn drives the screw shaft 10 and the screw blades 11 to rotate. At the same time, a farm tricycle is used to transport concrete from the concrete mixer truck to the site. Near this device, concrete is poured into the feed hopper 13, allowing it to flow into the trough 5. The rotating screw shaft 10 and screw blades 11 propel the concrete towards the discharge port. After the flow rate is controlled by the regulating plate 16, the concrete enters the channel embankment template 25. During this process, the position of the regulating plate 16 can be adjusted by loosening the nut 20 and sliding the horizontal screw 17. Once the position is appropriate, the nut 20 is tightened to adjust the area of ​​the discharge port, thereby controlling the outflow rate and discharge speed of the concrete. After the construction of this channel section is completed, the engine 2 is turned off, the connection between the support column 15 and the channel embankment template 25 is released, and the rear end of the trough 5 is manually lifted. By pushing the handle 19 in conjunction with the main traveling wheel 4 and the auxiliary traveling wheel 14, the device is pushed to the next construction section to continue the construction of the next section. This completes the use of the device. It overcomes the problems of low construction efficiency, inconvenient equipment movement, and significant safety hazards that exist in existing concrete conveying methods when raising the channel embankment next to the narrow side of the channel top road.

[0040] In the specific implementation process, the diameter of the driving pulley 3 is 8cm; the diameter of the driven pulley 12 is 40cm; the length of the trough 5 is 7m, and the middle part of the trough 5 is detachable; the diameter of the spiral blade 11 is 20cm; the main traveling wheel 4 uses a rubber tire with a diameter of 30cm; the lifting handrail 18 is made of galvanized steel pipe with a diameter of 5cm and a length of 40cm; the adjusting plate 16 is made of steel plate with a thickness of 2mm, and two angle steels with a side width of 3cm can be welded to the steel plate as support.
