Detailed Description of the Invention

[0025] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention referred to in the following description are usually only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] A road construction earth loading and transporting equipment, as Figure 1 shown, includes a hopper 1. The hopper 1 includes a bottom plate and a plurality of side plates arranged above the bottom plate. The bottom plate and the side plates enclose a receiving space for accommodating earth. The equipment is a push type, that is, the feeding port is arranged at the front end of the hopper 1, and the user stands at the rear end of the hopper 1. During use, the user slowly pushes it forward. An excavation mechanism is arranged at the feeding port for feeding earth into the hopper 1.

[0028] In addition, a ground walking mechanism is further arranged below the hopper 1 to facilitate the movement of the hopper 1. In this embodiment, the ground walking mechanism includes a steering wheel and a plurality of driving wheels 8 to drive the hopper 1 to move, and the arrangement of the steering wheel is more convenient for adjusting the moving direction of the hopper 1.

[0029] The excavation mechanism includes an excavation component, a mounting component, and a driving component. Among them, the mounting component is used to mount the excavation component, and the driving component is used to drive the excavation component so that the excavation component can send the earthwork into the hopper 1.

[0030] The mounting component includes two mounting frames 31, which are symmetrically arranged on both sides of the feeding port and fixedly connected to the side plates of the hopper 1. Both mounting frames 31 are provided with arc-shaped grooves 35 for the excavation component to slide. The mounting component further includes a fixed shaft 32, a rotating shaft 33, and an adjusting arm 34. Among them, the fixed shaft 32 is installed at the center of the arc-shaped groove 35, and the fixed shaft 32 is arranged outside the mounting frame 31. The rotating shaft 33 sequentially passes through the arc-shaped grooves 35 provided on the two mounting frames 31 and is placed inside the arc-shaped grooves 35. The adjusting arm 34 is arranged outside the mounting frame 31, and one end of the adjusting arm 34 is rotatably connected to the fixed shaft 32, and the other end is rotatably connected to the rotating shaft 33.

[0031] The excavation component is arranged between the two mounting frames 31 and includes a plurality of buckets 2, which are mounted on the rotating shaft 33 and are circumferentially distributed. There is an excavation opening 7 below the two mounting frames 31. When the buckets 2 excavate the earthwork on the road surface, the buckets 2 extend out from the excavation opening 71, so that the buckets 2 contact the road surface, dig the earthwork on the road surface, and then put the dug earthwork into the hopper 1. The setting of a plurality of buckets 2 can shorten the excavation time and improve the excavation efficiency. In this embodiment, the number of buckets 2 is set to 3.

[0032] To facilitate the entry of earthwork into the hopper 1, a guide plate 6 is provided below the feeding port. The guide plate 6 is connected to the bottom plate of the hopper 1 and is inclined. Here, the inclined setting means that the height of the connection side of the guide plate 6 to the bottom plate from the ground is lower than the height of the side close to the bucket 2 from the ground, that is, the guide plate 6 is inclined with the front high and the rear low.

[0033] The driving component is used to drive the operation of the excavation component, and it includes a power part and a rotating part. Among them, the power part is used to drive the excavation component to move up and down to realize the excavation of earthwork; the rotating part is used to drive a plurality of buckets 2 to rotate to realize the continuous excavation of earthwork by the excavation component.

[0034] The power part includes a hydraulic telescopic pump 42 and a driving block 41. Among them, the hydraulic telescopic pump 42 is arranged on the mounting frame 31, the driving block 41 is fixedly connected to the adjusting arm 34, and the output shaft of the hydraulic telescopic pump 42 is rotatably connected to the driving block 41. When the equipment moves to the excavation point, the hydraulic telescopic pump 42 can drive the driving block 41 to move up and down, the driving block 41 drives the adjusting arm 34 to rotate around the fixed shaft 32, and the adjusting arm 34 further drives the rotating shaft 33 to move along the arc-shaped groove 35 to realize the digging and dumping of the earthwork on the road surface by the bucket 2.

[0035] The rotating part includes a motor 43 and a mounting base, where the mounting base is used to mount the motor 43. The mounting base is fixedly installed on the adjusting arm 34, the motor 43 is fixedly installed on the mounting base, and the output shaft of the motor 43 is fixedly connected to the rotating shaft 33 to drive the rotating shaft 33 to rotate, thereby driving the buckets 2 mounted on the rotating shaft 33 and distributed in a circular pattern to rotate, so as to achieve continuous excavation of soil.

[0036] A discharging part is provided at one side plate of the hopper 1 for discharging the soil in the hopper 1. The discharging part includes a discharge port 51 provided on the side plate of the hopper 1, and a baffle 52 for blocking the discharge port 51 is installed at the discharge port 51. The baffle 52 is rotatably connected to the side plate of the hopper 1 through a hinge 56. A fixing buckle 53 is provided on one side of the discharge port 51, and a fitting buckle 54 matching the fixing buckle 53 is provided on the side of the baffle 52 opposite to the hinge 56. The so-called "matching" means that when the baffle 52 completely blocks the discharge port 51, the fixing buckle 53 and the fitting buckle 54 are in a straight line in the vertical direction. At this time, the bolt 55 can pass through the fixing buckle 53 and the fitting buckle 54 in sequence, so that the fitting buckle 54 and the fixing buckle 53 are fixedly connected, thereby realizing the fixation between the baffle 52 and the hopper 1, and thus realizing the closing of the discharge port 51 by the baffle 52. When it is necessary to discharge the soil in the hopper 1, only the bolt 55 needs to be pulled out. At this time, the discharge port 51 can be opened by rotating the baffle 52, and the soil in the hopper 1 can be discharged from the discharge port 51.

[0037] The usage method of the pavement construction soil loading and transporting equipment disclosed in this embodiment is as follows:

[0038] After the equipment reaches the excavation point, the hydraulic telescopic pump 42 drives the driving block 41 to move up and down. The driving block 41 drives the adjusting arm 34 to rotate around the fixed shaft 32. The adjusting arm 34 drives the rotating shaft 33 to move along the arc-shaped groove 35, so that the bucket 2 extends out of the excavation port 7 and contacts the road surface. At the same time, the motor 43 drives the rotating shaft 33 to drive a plurality of buckets 2 to rotate, so as to realize continuous excavation of the pavement soil. When the bucket 2 contacts the road surface, the soil on the road surface is dug by the bucket 2. When the bucket 2 rotates to the top, the soil in the bucket 2 slides down onto the guide plate 6 under the action of gravity and then slides into the hopper 1 along the guide plate 6. When the equipment is transferred to the discharging location, the bolt 55 is pulled out, the baffle 52 is rotated to open the discharge port 51, and the soil in the hopper 1 is discharged from the discharge port 51, that is, the loading and transporting of the pavement construction soil is completed.

[0039] Embodiment 2

[0040] It is basically the same as Embodiment 1, except that the equipment is a towed type. That is, the feeding port is arranged at the rear end of the hopper 1, and the user stands at the front end of the hopper 1. When in use, the user slowly drags it forward.
