Description

Technical Field

[0001] This invention belongs to the field of civil engineering technology, and in particular relates to a material transport and unloading device for civil engineering sites. Background Technology

[0002] Civil engineering encompasses the construction of buildings, structures, and works within facilities and sites in various categories, including above-ground, underground, land, water, and underwater projects such as houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, and protection. It includes not only various technical activities such as surveying, design, construction, maintenance, and management during the construction process, but also the materials, equipment, and items consumed during the construction process.

[0003] Civil engineering projects are involved in the existence, activities, and development of all sectors of the national economy. Without civil engineering projects to construct the space and venues for these activities, the existence and development of these sectors would be impossible. All of this demonstrates the importance of civil engineering projects, hence they are also referred to as basic construction.

[0004] During civil engineering, earthwork needs to be transported. When transporting earthwork, the subsequent unloading problem needs to be considered. Most existing material transport and unloading devices simply dump the earthwork directly onto the ground, making it difficult to unload the earthwork to higher locations. Subsequently, lifting devices are needed to transport the earthwork again, increasing the workload and transportation costs. At the same time, a large amount of earthwork dumped in a short period of time will flow rapidly in all directions, resulting in the earthwork eventually piling up and scattering in the surrounding area. This makes it difficult to unload the earthwork accurately in the correct location, and the subsequent manual leveling of the earthwork is not conducive to use. Summary of the Invention

[0005] The purpose of this invention is to provide a material handling and unloading device for civil engineering sites, which aims to solve the problems mentioned in the background.

The material collection hopper is located between the first guide plate and the conveyor belt and covers the projection area of ​​the material discharge end of the conveyor belt onto the base. The end of the material collection hopper near the first guide plate is configured as a round tube structure and extends into the first guide plate.

[0013] As a further aspect of the present invention: multiple sets of spaced and parallel support shafts are rotatably installed inside the material box, the support shafts are distributed in the same plane and the support shafts are in rolling contact with the inner wall of the conveyor belt on the side away from the base.

[0014] As a further embodiment of the present invention: a second guide plate with a U-shaped cross-section is fixedly installed at the end of the material box away from the collection hopper. The second guide plate is set at an angle with the horizontal plane and is used in conjunction with the conveyor belt. The height of the second guide plate gradually decreases towards the side away from the conveyor belt, and a limit plate is fixedly connected to its lower end. The end of the limit plate away from the second guide plate is fixedly connected to the base.

[0015] As a further aspect of the present invention: a support column pointing towards the base is fixedly installed on the surface of the first guide plate near the base, and a U-shaped mounting bracket is rotatably installed at the end of the support column away from the first guide plate, and a roller that rolls in contact with the base is rotatably installed inside the mounting bracket.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] like Figures 1-9As shown, in a preferred embodiment of the present invention, a material transport and unloading device for civil engineering sites includes a base 1, a handrail 28 fixedly installed at one end of the base 1, a material transport box 2 fixedly installed on the base 1, and symmetrically distributed bottom plates 3 fixedly installed inside the material transport box 2. The bottom plates 3 are set at an angle with the horizontal plane, and the bottom plates 3 are set with the outer side higher than the inner side and the lower ends of the two bottom plates 3 are separated. A closing plate 4 is rotatably installed inside the material transport box 2. The closing plate 4 is distributed along the length direction of the material transport box 2 and slides in contact with the lower end of the bottom plate 3.

[0035] Both ends of the material box 2 are provided with through slots near the base 1, and the material box 2 is rotatably installed with spaced mounting shafts 6. The mounting shafts 6 are located in the same plane and between the base 1 and the bottom plate 3. The mounting shafts 6 are rotatably installed with a conveyor belt 7 distributed along the length of the material box 2. The outer side of the material box 2 is fixedly installed with an output shaft and a second rotating power component 9 fixedly connected to one of the mounting shafts 6.

[0036] A mounting column 11 is rotatably mounted on the base 1. The mounting column 11 is located in the projection area of ​​the end of the conveyor belt 7 onto the base 1. A first guide plate 12 with a U-shaped cross section is fixedly mounted on the end of the mounting column 11 away from the base 1. The first guide plate 12 has an angle with the horizontal plane and its height gradually decreases towards the end away from the mounting column 11.

[0037] A column 18 is fixedly installed on the base 1 at the end away from the first guide plate 12. A rotating plate 19 is rotatably installed on the end of the column 18 away from the base 1. A winch 24 is fixedly installed on both ends of the rotating plate 19. A wire rope 25 is wound on the winch 24. A U-shaped connecting frame 26 is fixedly connected to the movable end of the wire rope 25. A transfer box 27 is rotatably installed inside the connecting frame 26. A power component 32 that drives the rotating plate 19 to rotate is provided on the column 18.

[0038] Both sides of the closed plate 4 are set as semi-circular structures, and the lower end of the bottom plate 3 is set as an arc structure. The arc structure of the bottom plate 3 is part of the circle drawn when the closed plate 4 rotates.

[0039] The material box 2 is fixedly installed with a first rotating power component 5 at one end. The output shaft of the first rotating power component 5 is fixedly connected to the sealing plate 4. The axis of the output shaft of the first rotating power component 5 and the axis of the sealing plate 4 are on the same straight line.

[0040] A material collection hopper 10 is fixedly installed at one end of the material box 2. The material collection hopper 10 is located between the first guide plate 12 and the conveyor belt 7 and covers the projection area of ​​the discharge end of the conveyor belt 7 onto the base 1. The end of the material collection hopper 10 near the first guide plate 12 is set as a round tube structure and extends into the first guide plate 12.

[0041] A second guide plate 16 with a U-shaped cross-section is fixedly installed at the end of the material box 2 away from the collection hopper 10. The second guide plate 16 is set at an angle with the horizontal plane and is used in conjunction with the conveyor belt 7. The height of the second guide plate 16 gradually decreases towards the side away from the conveyor belt 7, and a limit plate 17 is fixedly connected to its lower end. The end of the limit plate 17 away from the second guide plate 16 is fixedly connected to the base 1.

[0042] Multiple sets of spaced and parallel support shafts 8 are rotatably installed inside the material box 2. The support shafts 8 are distributed in the same plane and roll in contact with the inner wall of the conveyor belt 7 on the side away from the base 1.

[0043] A support column 13 pointing towards the base 1 is fixedly installed on the surface of the first guide plate 12 near the base 1. A U-shaped mounting bracket 14 is rotatably installed at the end of the support column 13 away from the first guide plate 12. A roller 15 that rolls and contacts the base 1 is rotatably installed inside the mounting bracket 14.

[0044] In practical application, the base 1 is moved to the location where the earthwork is generated by pushing the handle 28. At this time, the first rotating power component 5 drives the sealing plate 4 to rotate to a horizontal state. The sealing plate 4 then contacts the lower end of the base plate 3, thus completing the sealing of the lower side of the base plate 3. At this time, the earthwork can be loaded into the material box 2. After loading, the base 1 can be moved to the place where the earthwork needs to be transported. After moving to the designated position, when it is necessary to unload the earthwork on the ground, the first guide plate 12 is rotated. When rotating, the roller 15 rolls on the base 1, so that the support column 13 can stably support the first guide plate 12, ensuring the smoothness of the adjustment of the direction of the first guide plate 12, so that the end of the first guide plate 12 away from the material box 2 points to the unloading point of the earthwork. Then, the first rotating power component 5 drives the sealing plate 4 to rotate. The rotation of the sealing plate 4 will create a gap with the base plate 3, so that the earthwork in the material box 2 can fall to the lower side onto the conveyor belt 7 through the gap. At the same time, the rotation of the sealing plate 4 can push the earthwork. The soil flows within the material container 2, allowing it to fall steadily downwards. The continuous rotation of the sealing plate 4 creates alternating gaps between it and the bottom plate 3, preventing large amounts of soil from falling simultaneously and ensuring stable unloading. Simultaneously, the second rotating power component 9 drives one set of mounting shafts 6, causing the conveyor belt 7 to rotate and transport the soil along it towards the first guide plate 12. Driven by the conveyor belt 7, the soil moves and eventually falls downwards into the collection hopper 10. From there, it falls onto the first guide plate 12. Because the first guide plate 12 is inclined, the soil moves along it to the ground, achieving automatic unloading. The even downward unloading ensures precise placement of the soil at the correct location. The adjustment of the first guide plate 12 allows for even spreading of the soil, eliminating the need for manual spreading and improving usability.

[0045] When it is necessary to unload soil to different heights, the second rotating power component 9 rotates in the opposite direction, causing the conveyor belt 7 to rotate in the opposite direction and move the soil on it to the other end. The winch 24 releases the wire rope 25, placing the transfer box 27 on the base 1 with one end tightly against the limiting plate 17. At this time, the soil falls from the conveyor belt 7 onto the second guide plate 16 and moves down along the second guide plate 16 into the transfer box 27. After the transfer box 27 is full, the winch 24 winds up the wire rope 25 and lifts the transfer box 27 to the required unloading height. Then, the power component 32 drives the rotating plate 19 to rotate slowly, thereby rotating the transfer box 27 to the position where the soil needs to be unloaded. Then, the soil in the transfer box 27 can be unloaded. When the soil above is unloaded, another set of... The transfer box 27 is placed on the base 1 to receive the soil. After another set of soil is unloaded, the unloading of soil can continue. This allows for continuous and uninterrupted unloading of soil from the transfer box 2, ensuring the speed of soil unloading. This is beneficial for use and allows for convenient automatic unloading of soil at ground level and different heights. The unloading method can be adjusted according to the specific unloading position and height of the soil, improving unloading flexibility, reducing the limitations of the device, and increasing the scope and practicality of the device. During unloading, the position of the soil pile can be flexibly adjusted to facilitate unloading at designated locations, improving the accuracy of unloading. Unloading can be carried out continuously and uninterruptedly at both ground level and different heights, improving the speed and efficiency of unloading, which is beneficial for use.

[0046] In one embodiment of the present invention, the first rotating power component 5 and the second rotating power component 9 are respectively a first motor and a second motor. Of course, they can also be other components that can output rotational power, such as a hydraulic motor. The first motor drives the closed plate 4 to rotate, thereby realizing the uniform outflow of soil. The second motor drives the conveyor belt 7 to rotate, thereby realizing the transportation of soil to both sides and realizing the material discharge requirements at different locations.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in a preferred embodiment of the present invention, an L-shaped baffle 29 is slidably installed on the side wall of the material box 2 away from the base 1. The right-angle section of the baffle 29 is located inside the material box 2 and the baffle 29 penetrates the side wall of the material box 2. Both ends of the two side walls of the material box 2 are threaded with fixing screws 30. The fixing screws 30 are used in conjunction with fixing holes 31 opened on the baffle 29. Multiple sets of fixing holes 31 are provided and distributed on both sides of the baffle 29.

[0048] In practical application, during loading, the fixing screw 30 is rotated to move away from the fixing hole 31. Then, the baffle 29 is pushed outward so that the vertical section of the baffle 29 contacts the side wall of the material box 2. At this time, the baffle 29 can be used to seal the material box 2. Then, soil material can be put into the material box 2. When the material box 2 is full of soil, the baffle 29 is pushed inward so that the baffles 29 on both sides contact each other. Then, the fixing screw 30 is rotated to enter the fixing hole 31 on the outer side of the baffle 29, thereby fixing the baffle 29. At this time, the baffle 29 can seal the upper part of the material box 2, thereby preventing the soil from falling outward during subsequent transportation, avoiding the impact on the road surface during transportation, and contributing to the cleanliness and passability of the road surface.

[0049] like Figure 1 , Figure 5 and Figure 9 As shown, in a preferred embodiment of the present invention, the power assembly 32 includes a support plate 20, which is fixedly mounted on the column 18 and located at the end away from the base 1. A third rotating power component 21 is fixedly mounted on the surface of the support plate 20 away from the base 1. The output shaft of the third rotating power component 21 is parallel to the column 18 and a gear 22 is fixedly mounted at the end of its output shaft. A gear ring 23 fixedly mounted on the rotating plate 19 meshes with the outside of the gear 22.

[0050] The gear ring 23 is distributed around the column 18 and the axis of the gear ring 23 coincides with the axis of the column 18.

[0051] In practical application, after the transfer box 27 is filled with soil, it is lifted to the upper part by the winch 24. Then, the third rotating power component 21 drives the gear 22 to rotate. The gear 22 drives the rotating plate 19 to rotate slowly through the meshing gear ring 23. Thus, the rotating plate 19 can drive the transfer box 27 containing soil to a suitable position. Then, the transfer box 27 can unload the soil at a suitable height. At the same time, the transfer box 27 on the other side can be placed on the base 1 to receive the soil, thereby realizing the continuous unloading and transfer of soil and improving the speed and efficiency of soil transfer.

[0052] In one embodiment of the present invention, the third rotating power component 21 is a third motor, but it can also be a hydraulic motor or other components capable of outputting rotational power. The third motor drives the rotating plate 19 to rotate slowly through the meshing gear 22 and gear ring 23, thereby changing the position of the transfer box 27 for convenient unloading.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
