Description
Technical Field
[0001] This application relates to the field of concrete construction, and in particular, to a wheeled concrete loader and unloader. Background Art
[0002] A wheeled loader is an earthwork construction machine widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling loose materials such as soil, sand, gravel, lime, coal, etc., and can also perform light shoveling operations on ores, hard soil, etc. It plays an important role in reducing labor intensity, accelerating the project construction speed, and improving project quality. A wheeled loader generally consists of a vehicle body and an auxiliary working device installed on the vehicle body and controlled by a hydraulic system to perform actions. The auxiliary working device is generally a forklift bucket. By replacing different auxiliary working devices, it can also perform earthmoving, lifting and loading and unloading operations of other materials such as wood.
[0003] In concrete construction, wheeled loaders are also widely used, also called wheeled concrete loaders and unloaders. Existing wheeled concrete loaders and unloaders include a vehicle body, a supporting auxiliary working device forklift bucket, and a hydraulic system that controls the forklift bucket to perform complex movements. By placing the forklift bucket beside the concrete pile after mixing, the vehicle body moves forward with the forklift bucket to shovel the concrete into the forklift bucket.
[0004] When the existing concrete loader and unloader shovels concrete, since the concrete will be driven to move forward, the loading effect is not good and it needs to be loaded repeatedly or moved forward continuously, especially when the amount of concrete is small. Content of the Utility Model
[0005] In order to better load and transport concrete, this application provides a wheeled concrete loader and unloader.
[0006] The wheeled concrete loader and unloader provided by this application adopts the following technical solutions:
[0007] A wheeled concrete loader and unloader includes a vehicle body, a forklift bucket installed on the vehicle body, and an accessory component installed on the forklift bucket. The accessory component includes an accessory shovel cover and a cover closing and opening driving member. The opening of the forklift bucket faces the accessory shovel cover. There are two cover closing and opening driving members, and the two cover closing and opening driving members are respectively arranged on both sides of the forklift bucket. The cover closing and opening driving member drives the accessory shovel cover to perform movements of opening and closing the opening of the forklift bucket.
[0008] By adopting the above technical solution, an auxiliary shovel cover is provided on the forklift bucket. The auxiliary shovel cover can move closer to and away from the forklift bucket through a cover closing driving member. When a small amount of concrete is shoveled, by placing the forklift bucket and the auxiliary shovel cover on the ground, with the concrete located between the auxiliary shovel cover and the forklift bucket, the forklift bucket shovels the concrete. During this process, the forklift bucket moves towards the auxiliary shovel cover, and the cover closing driving member drives the auxiliary shovel cover towards the forklift bucket, causing the forklift bucket to move relative to the concrete while the auxiliary shovel cover remains stationary relative to the concrete. If the concrete moves under the push of the forklift bucket, it is restricted by the auxiliary shovel cover, and the concrete can be better shoveled into the forklift bucket, facilitating the loading and transfer of the concrete.
[0009] Optionally, it further includes a rotation driving member. There are two rotation driving members, which are respectively arranged on both sides of the forklift bucket. The rotation driving member drives the cover closing driving member and the auxiliary shovel cover to turn up and cross over the opening of the forklift bucket.
[0010] By adopting the above technical solution, by setting the rotation driving member, the rotation driving member can drive the auxiliary shovel cover to turn up, enabling the forklift bucket to also turn up the auxiliary shovel cover for separate use when in use. The auxiliary shovel cover does not affect the forklift bucket, and the usage method is more diverse.
[0011] Optionally, it further includes mounting plates. There are two mounting plates, and the two mounting plates correspond to the two cover closing driving members one by one. The mounting plates are rotatably installed on the side wall of the forklift bucket and are used for installing the cover closing driving member. Both the cover closing driving member and the rotation driving member are hydraulic cylinders. One end of the rotation driving member is rotatably installed on the side wall of the forklift bucket, and the piston rod of the rotation driving member is rotatably connected to the mounting plate to drive the mounting plate to rotate.
[0012] By adopting the above technical solution, the mounting plate is provided for installing the cover closing driving member, and at the same time, the mounting plate is rotatably connected to the forklift bucket. Compared with the cover closing driving member being directly rotatably connected to the forklift bucket, the rotation driving member applies force to the cover closing driving member. By setting the mounting plate, the cooperation between the cover closing driving member and the rotation driving member can be better achieved. By driving the mounting plate to rotate, the cover closing driving member and the corresponding auxiliary shovel cover are driven to rotate.
[0013] Optionally, the mounting plate is provided with mounting holes, and the auxiliary shovel cover is provided with connecting rods, and the connecting rods are slidably inserted into the mounting holes.
[0014] By adopting the above technical solution, the auxiliary shovel cover is associated with the mounting plate through the connecting rod, enabling the cover closing driving member to mainly play the function of pushing and pulling the auxiliary shovel cover, and the cover closing driving member does not play the main function of connecting the auxiliary shovel cover and the forklift bucket, reducing the bearing pressure of the cover closing driving member.
[0015] Optionally, a travel block is provided on the side wall of the forklift bucket. The travel block abuts against the mounting plate and restricts the rotation of the auxiliary shovel cover between the opening and the upper part of the forklift bucket by restricting the mounting plate.
[0016] By adopting the above technical solution, by providing a travel block, the rotation stroke of the mounting plate is within a certain range, which not only realizes the conversion of the two states of the auxiliary shovel cover, but also reduces the pressure on the rotation driving member.
[0017] Optionally, when the auxiliary shovel cover faces the opening of the forklift bucket, the auxiliary shovel cover is inclined away from the forklift bucket towards the lower side of the side wall of the forklift bucket.
[0018] By adopting the above technical solution, it is not easy for concrete to remain on the auxiliary shovel cover, and it is more convenient to clean the auxiliary shovel cover subsequently.
[0019] Optionally, reinforcing ribs are provided on the side wall of the auxiliary shovel cover facing the forklift bucket. The reinforcing ribs are evenly distributed, and the surface of the reinforcing ribs is an arc surface.
[0020] By adopting the above technical solution, the reinforcing ribs improve the strength of the auxiliary shovel cover, and the arc-shaped surface of the reinforcing ribs reduces dead corners and gaps, facilitating subsequent concrete cleaning.
[0021] Optionally, a weight-reducing groove is formed on the side wall of the auxiliary shovel cover facing away from the forklift bucket. A cover plate is provided at the lower part of the side of the auxiliary shovel cover facing away from the forklift bucket. The cover plate is integrated with the auxiliary shovel cover and covers part of the weight-reducing groove.
[0022] By adopting the above technical solution, the weight-reducing groove is provided to reduce the force application requirements of the cover closing driving member and the rotation driving member. At the same time, the cover plate prevents concrete from filling the lower weight-reducing groove.
[0023] In summary, by matching an auxiliary shovel cover on the forklift bucket, the auxiliary shovel cover can move closer to and away from the forklift bucket through a cover closing driving member. When the amount of concrete shoveled is less, by placing the forklift bucket and the auxiliary shovel cover on the ground, with the concrete located between the auxiliary shovel cover and the forklift bucket, the forklift bucket shovels the concrete. During this process, the forklift bucket moves towards the auxiliary shovel cover, and the cover closing driving member drives the auxiliary shovel cover towards the forklift bucket, causing the forklift bucket to move relative to the concrete while the auxiliary shovel cover remains stationary relative to the concrete. If the concrete moves under the push of the forklift bucket, it is restricted by the auxiliary shovel cover, better shoveling the concrete into the forklift bucket and facilitating the loading and transfer of the concrete.

DETAILED DESCRIPTION
[0030] The following is combined with Figures 1-5 This application is described in further detail.
[0031] The embodiment of the present application discloses a wheeled concrete loader.
[0032] Reference Figure 1 A wheeled concrete loader comprises a body 1, a forklift bucket 2 mounted on the body 1 and an auxiliary component 3 mounted on the forklift bucket 2. The forklift bucket 2 is a shell with an opening on one side. The forklift bucket 2 is connected to the body 1 on the side facing away from the opening. The cross section of the forklift is V-shaped, and the forklift bucket 2 is a smooth arc surface around the outer wall of the opening.
[0033] Reference Figures 2-5 The accessory component 3 includes an accessory shovel cover 4, a mounting plate 5, a cover-collecting driving member 6, a rotating driving member 7 and a travel block 8, wherein the mounting plate 5, the cover-collecting driving member 6, the rotating driving member 7 and the travel block 8 form a set of driving structures. In this embodiment, the driving structure has two sets correspondingly installed on the side walls on both sides of the opening of the shovel bucket 2 for driving both sides of the accessory shovel cover 4.
[0034] The auxiliary shovel cover 4 is a plate. One surface of the auxiliary shovel cover 4 is set as the force - applying surface 41, and the corresponding back surface is set as the structural surface 42. A weight - reducing groove 43 is formed on the structural surface 42 of the auxiliary shovel cover 4. There are multiple weight - reducing grooves 43, and the multiple weight - reducing grooves 43 are arrayed on the structural surface 42. At the same time, a cover plate 44 is welded and fixed at the lower part of the structural surface 42 of the auxiliary shovel cover 4. The cover plate 44 covers all the weight - reducing grooves 43 at the lower part of the structural surface 42. In this embodiment, only the upper three rows of weight - reducing grooves 43 are exposed. Taking the structural surface 42 as the vertical plane, the part of the force - applying surface 41 corresponding to the side of the cover plate 44 away from the exposed weight - reducing grooves 43 bulges outwards, making the force - applying surface 41 inclined relative to the structural surface 42. At the same time, reinforcing ribs 45 are arranged on the force - applying surface 41. The reinforcing ribs 45 are evenly distributed. In this embodiment, the reinforcing ribs 45 divide the surface of the force - applying surface 41 into a grid of Chinese character 'tian', and the surface of the reinforcing ribs 45 is an arc surface. In this embodiment, the cross - section of the reinforcing ribs 45 is a minor - arc bow - shaped.
[0035] When the auxiliary shovel cover 4 is installed on the forklift bucket 2, the force - applying surface 41 of the auxiliary shovel cover 4 faces the forklift bucket 2. At the same time, when the forklift bucket 2 is placed on the ground with the opening facing horizontally, the cover plate 44 of the auxiliary shovel cover 4 is also close to the ground.
[0036] In this embodiment, both the closing drive member 6 and the rotation drive member 7 adopt hydraulic cylinders. The mounting plate 5 is a square plate. The middle part of the mounting plate 5 is rotationally connected to the side wall of the forklift bucket 2 by driving a rotating shaft. The mounting plate 5 is provided with a mounting hole 51 through it. A connecting rod 46 is welded and fixed to the auxiliary shovel cover 4, and the connecting rod 46 is slidably inserted into the mounting hole 51. The sliding mode is the same as that of the piston rod and filled with lubricating oil. A stroke block 8 is also protrudingly and overhangingly arranged on the side wall of the forklift bucket 2. The stroke block 8 is also a square block. The stroke block 8 abuts against the mounting plate 5 and limits the rotation angle of the mounting plate 5 to 90 degrees. Specifically, the stroke block 8 is located below the mounting plate 5. When the force - applying surface 41 of the auxiliary shovel cover 4 faces the opening of the forklift bucket 2, the mounting plate 5 abuts against one side wall of the stroke block 8. When the mounting plate 5 rotates 90 degrees, the auxiliary shovel cover 4 flips over the forklift bucket 2, and the mounting plate 5 abuts against the other side wall of the stroke block 8.
[0037] The shortest distance from the plane where the surfaces that the above - mentioned stroke block 8 and the mounting plate 5 abut against each other in the two states to the rotation center of the mounting plate 5 is the same.
[0038] The rotation drive member 7 is located below the stroke block 8. A connecting groove 52 is formed on the side wall of the mounting plate 5 that abuts against the stroke block 8 and away from the auxiliary shovel cover 4. The cylinder body of the rotation drive member 7 is hinged to the side wall of the forklift bucket 2, and the piston rod of the rotation drive member 7 extends into the connecting groove 52 for hinging. When the auxiliary shovel cover 4 is in the state facing the opening of the forklift bucket 2, the hinge point of the rotation drive member 7 and the forklift bucket 2 is located on the side of the mounting plate 5 close to the auxiliary shovel cover 4, ensuring that the rotation drive member 7 can drive the mounting plate 5 to rotate to the corresponding angle.
[0039] Correspondingly, by restricting the mounting plate 5, the auxiliary shovel cover 4 is restricted to rotate between the opening and above of the forklift bucket 2. The rotation driving member 7 can also be hinged to the surface of the mounting plate 5. However, in order to reduce interference, the present application preferably performs the hinge connection within the connection groove 52.
[0040] The cover closing driving member 6 is mounted on the mounting plate 5 and is used to drive the auxiliary shovel cover 4 to move closer to and away from the forklift bucket 2. Specifically, the cylinder block of the cover closing driving member 6 is fixed to the mounting plate 5, and the piston rod of the cover closing driving member 6 is connected to the auxiliary shovel cover 4. The driving direction of the cover closing driving member 6 is the same as the sliding direction of the connecting rod 46 within the mounting hole 51.
[0041] The implementation principle of the wheeled concrete loader in the embodiment of the present application is as follows: By the sliding ability of the auxiliary shovel cover 4 relative to the forklift bucket 2, the object is restricted from moving away from the forklift bucket 2.
[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
