Description

Technical Field

[0001] The utility model relates to the technical field of earthwork construction, in particular to a loader for earthwork construction. Background Art

[0002] A loader is a type of earthwork machinery widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. It is mainly used to shovel bulk materials such as soil, sand, lime, and coal, and can also perform light excavation operations on ore and hard soil.

[0003] At present, sand and gravel loaders are mainly bucket shovel trucks. When the transport vehicles traveling to and from the earthwork engineering area need to load sand and gravel, they must cooperate with the bucket shovel truck to transfer the sand and gravel into the transfer compartment. However, this method of transporting sand and gravel requires the cooperation of two vehicles to complete, and the efficiency of sand and gravel loading will also be different due to the operating capabilities of different drivers.

[0004] For vehicles loading sand and gravel in earthwork projects, how to improve the efficient loading of sand and gravel by the transfer vehicles without the need for the coordination of bucket trucks is a technical difficulty that needs to be solved. Summary of the invention

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in this utility model is:

[0007] The loader for earthwork construction comprises a traction mechanism, a transfer mechanism installed on the traction mechanism and a pushing mechanism installed on the transfer mechanism, wherein the traction mechanism comprises a beam frame fixedly installed on the outside of two load-bearing outer frames, a pull rod movably installed in the beam frame and a gasket fitted on the inner end of the pull rod, the transfer mechanism comprises two load-bearing outer frames, three auxiliary rotation rollers movably installed on the inner sides of the two load-bearing outer frames, a transmission roller movably installed between the two load-bearing outer frames, a material transfer conveyor belt driven by the auxiliary rotation rollers and the transmission rollers, a material guiding partition located at the bottom ends of the two load-bearing outer frames, a chassis fixedly installed on the top of one of the load-bearing outer frames, a motor installed inside the chassis, a crawler belt transmission-connected to the motor transmission shaft and a linkage assembly located directly below the chassis, and the pushing mechanism comprises two columns fixedly installed on the tops of the two load-bearing outer frames, a truss installed on the tops of the two columns, a first vertical shaft and a second vertical shaft movably installed in the truss, two gear plates respectively fixedly installed on the first vertical shaft and the second vertical shaft, a plurality of sleeves installed in the first vertical shaft and the second vertical shaft and a blade movably installed in the sleeves.

[0008] In a preferred example, the utility model can be further configured as follows: a bolt is movably installed in the transverse hole inside the gasket, and the bolt is movably installed in the threaded hole at the inner end of the pull rod.

[0009] By adopting the above technical solution, the inner end of the pull rod is fixed and locked by using bolts that penetrate into the horizontal holes of the gasket. At this time, the assembled pull rod can cooperate with the beam frame to provide stable traction to the two load-bearing outer frames. When the outer end of the pull rod is installed in the rear compartment of the transfer vehicle, as the transfer vehicle reverses toward the sand and gravel, the material guide baffle attached to the ground can transfer the sand and gravel to the transfer conveyor belt.

[0010] In a preferred example, the utility model can be further configured as follows: the load-bearing outer frame is made of stainless steel material, and two T-shaped legs are fixedly installed on the bottom of the load-bearing outer frame, and rollers are movably installed in the grooves of the T-shaped legs.

[0011] By adopting the above technical solution and utilizing the strength of the two load-bearing outer frames themselves, when the two assembled load-bearing outer frames cooperate with the transfer vehicle to travel on the ground, the material-introducing partition with adjusted angle can provide a platform for inducing the sand and gravel scattered on the ground, and cooperate with multiple rotating middle blades to guide the sand and gravel.

[0012] In a preferred example, the utility model can be further configured as follows: raised partitions are evenly installed on the outside of the transfer conveyor belt.

[0013] By adopting the above technical solution, the sand and gravel are blocked by the partitions evenly distributed outside the transfer conveyor belt. As the sand and gravel are continuously pushed to the top of the material-introducing partition and smoothly fall to the outside of the transfer conveyor belt, the sand and gravel blocked by the partition can be quickly transferred to the inside of the transfer carriage.

[0014] In a preferred example, the utility model can be further configured as follows: the linkage assembly is composed of a deflection gear shaft and two positioning fixtures, and the deflection gear shaft penetrates into the inner cavities of the two positioning fixtures.

[0015] By adopting the above technical solution, the deflection gear shaft is assembled on the outside of one of the load-bearing outer frames using two positioning fixtures. As the motor runs, its internal transmission shaft will cooperate with the bottom gear to jointly drive the deflection gear shaft, and then transmit the transmission roller shaft.

[0016] In a preferred example, the utility model can be further configured as follows: an auxiliary end is fixedly installed on the top of the first vertical axis, and the outer walls of the bottom turntables of the first vertical axis and the second vertical axis are provided with inwardly recessed horizontal holes, rivets are installed in the vertical holes inside the sleeve, and the bottom ends of the rivets are adapted to penetrate through the holes of the guide rods at the inner ends of the blades.

[0017] By adopting the above technical solution, multiple sleeves are pre-installed in the turntable at the bottom of the first vertical axis and the second vertical axis respectively, and the guide rod at the inner end of the blade is assembled in the inner cavity of the sleeve, combined with the fixation of the blade and the sleeve with rivets, at this time, multiple blades can be distributed in a circular shape just above the material introduction partition. With the high-speed rotation of the blade, the sand and gravel on the ground can be quickly transferred to the material introduction partition and the material transfer conveyor belt.

[0018] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. When the outer end of the pull rod of the utility model is selected to be assembled in the rear compartment of the transfer vehicle, as the driver drives the transfer vehicle to reverse towards the sand and gravel, the material introduction baffle in contact with the ground can cooperate with the high-speed rotating first vertical axis, the second vertical axis and a plurality of blades to push the sand and gravel scattered on the ground toward the top inclined surface of the material introduction baffle. When the sand and gravel are continuously pushed to the top surface of the material introduction baffle, the continuously compressed sand and gravel will be transferred along the material transfer conveyor belt to the compartment of the transfer vehicle, thereby effectively ensuring that the loading equipment can independently cooperate with each transfer vehicle to efficiently load the sand and gravel.

[0042] By pre-installing multiple sleeves 360 in the turntable at the bottom of the first vertical axis 330 and the second vertical axis 340, and assembling the guide rod at the inner end of the blade 370 in the inner cavity of the sleeve 360, and fixing the blade 370 and the sleeve 360 ​​with rivets, the multiple blades 370 can be distributed in a circle just above the material guide baffle 250. With the high-speed rotation of the blade 370, the sand and gravel on the ground can be quickly transferred to the material guide baffle 250 and the material transfer conveyor belt 240.

[0043] The working principle and use process of the utility model are as follows: the two columns 310 are respectively fixedly installed at the two ends of the truss 320 in advance, and then the two assembled gear plates 350, the first vertical shaft 330 and the second vertical shaft 340 are respectively installed in the two end plates in the middle of the truss 320 with bolts and washers. At this time, the two gear plates 350 will be in a meshing state, and then the multiple blades 370 are respectively assembled in the inner cavities of the multiple sleeves 360 by rivets. At this time, the rivets that penetrate into the inside of the sleeves 360 will fix the blades 370, and then the two assembled columns 310 are respectively fixed on the tops of the two load-bearing outer frames 210. At this time, the crawler 280 will be connected to the first vertical shaft 330 and the two auxiliary ends on the transmission shaft in the motor 270;

[0044] During use, the operator needs to pre-assemble the outer end of the pull rod 120 on the tail of the transfer engineering vehicle, and then adjust the angle adjustment bolts at the bottom of the two load-bearing outer frames 210 until the outer end of the material-introducing baffle 250 fits against the ground. Then the operator needs to drive the transfer vehicle in reverse toward the sand and gravel. At the same time, the operation of the motor 270 will cause its internal transmission shaft to cooperate with the crawler 280 to drive the first vertical shaft 330 to rotate at high speed. With the meshing transmission of the two material-introducing baffles 250, the positioned and clamped second vertical shaft 340 will also rotate at the same speed. At this time, the multiple blades 370 installed at the bottom of the first vertical shaft 330 and the second vertical shaft 340 can quickly transfer the scattered sand and gravel on the surface to the transfer conveyor belt 240, and the transferred sand and gravel will finally be transferred by the transfer conveyor belt 240 to the carriage of the transfer vehicle. At this time, each independent transfer vehicle can quickly load sand and gravel without the cooperation of a forklift.
