Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a construction material transfer vehicle that is convenient for loading and unloading. Background Art

[0002] During the construction of a construction project, transport trucks transport the relevant building materials to the construction site. Then, according to the needs of the specific construction site, the workers transfer the relevant building materials to the construction site. The transferred materials often have a certain weight, so workers usually use construction transfer devices to transfer and load and unload the building materials. The road surface on the construction site is usually uneven and there are many narrow areas, so a flexible and convenient transfer vehicle is needed.

[0003] The existing announcement number is CN220096411U, and the patent is named "A transfer device for construction projects". This utility model relates to the field of construction transfer technology and proposes a transfer device for construction projects, including a transfer seat. Bearings are fixedly connected to both sides of the inner wall of the transfer seat, and the inner wall of the transfer seat is fixedly connected to the outer ring of the bearing. A lifting control instrument is fixedly connected to the bottom mounting groove of the transfer seat, and a lifting limit tube is fixedly connected to the top symmetrical circular groove of the lifting control instrument. A lifting push rod is movably connected to the inner cavity of the lifting limit tube. A transfer loading box is installed on the top of the transfer seat. This utility model tilts the transfer loading box to complete the dumping of the construction materials in the transfer loading box after transfer. When the construction materials to be transferred and dumped have a certain weight, this design replaces the manual handling and unloading of the construction materials in the transfer loading box by the construction staff, thereby reducing the subsequent transportation time of the construction materials by reducing the unloading time of the construction materials.

[0004] The above-mentioned device completes the dumping work of the construction materials in the transfer loading box after transfer by tilting the transfer loading box, replacing the construction workers to manually carry and unload the construction materials in the transfer loading box, thereby reducing the subsequent construction material transfer time by reducing the unloading time of the construction materials. However, the size of the device is too large, and it is difficult to pass through a small area on the construction site, and it cannot meet people's usage needs well. In view of the above situation, technical innovation is carried out on the basis of the existing construction material transfer vehicle. Utility Model Content

The screw rod drives the slider to move forward in the slide groove, thereby driving the discharge plate to move forward and pushing the material out of the bucket.

[0011] Furthermore, a transmission assembly is arranged below the right end of the truck bucket, and the transmission assembly includes a dustproof shell and a bevel gear 1, and a bevel gear 1 is arranged inside the dustproof shell.

[0012] Furthermore, the transmission assembly also includes a transmission shaft and a second bevel gear, the transmission shaft is meshed on the right side of the first bevel gear, and the second bevel gear is meshed at the lower middle portion of the transmission shaft.

[0013] Furthermore, a motor is arranged below the bevel gear 2, and the motor and the bevel gear 2 are welded. The motor drives the bevel gear 2 to rotate, and distributes the power to the two bevel gears 1 through the transmission shaft.

The electric lifting rod is extended, the bucket tilts forward, and at the same time, the motor drives the bevel gear 2 to rotate, and the power is distributed to the two bevel gears 1 through the transmission shaft. The dustproof shell prevents dust and stones from affecting the transmission. The two bevel gears 1 drive the screw rod to rotate, and the screw rod drives the slider to move forward in the slide groove, thereby driving the unloading plate to move forward and push the material out of the bucket.
