Description

Technical Field

[0001] The utility model relates to the field of wheelbarrows, in particular to a wheelbarrow which is convenient for unloading. Background Art

[0002] At present, handcarts are a very common means of transportation. Although the technology of transport vehicles is constantly developing, handcarts are still widely used in production and life due to their easy operation, light weight, ability to work in environments where motor vehicles are inconvenient to use, and obvious advantages in short-distance transportation. When unloading, traditional handcarts need to be manually pushed to flip the body of the truck bed, which is labor-intensive and inconvenient. Therefore, automatic unloading handcarts were born. A pushing mechanism is set at the bottom of the truck bed to push and flip the truck bed for unloading. Since the material in the truck bed is usually heavy, direct pushing by the pushing mechanism has high requirements on the power mechanism. In addition, during the overall flipping process, since the four walls of the truck bed have a certain height, it is necessary to reach a certain angle to achieve unloading. As the flipping angle increases, the center of gravity of the truck bed is unstable, which can easily cause the entire body to tip over. Utility Model Content

[0003] In order to make up for the above shortcomings, the utility model provides a trolley that is easy to unload, aiming to improve the problem that the entire trolley body is easily tipped over as the turning angle increases during unloading.

[0011] In a preferred technical solution of the present utility model, the bottom end of the first wheel is arranged parallel to the bottom end of the second wheel, the second wheel is smaller than the first wheel, and a handle is fixedly installed on one side of the base.

[0012] The beneficial effects of the utility model are as follows: the utility model obtains a handcart which is convenient for unloading through the above design. When the equipment is pushed to the unloading place, the motor is started to drive the threaded rod to rotate. The rotation of the threaded rod drives the support plate to move through the slide seat. The support plate drives the second wheel to move to the front of the discharge port through the L-shaped bracket. The electric push rod is started to drive the sealing cover to move up to the discharge port through the support block to open. At this time, the cylinder is started again to drive the support rod to move up. The support rod drives the material transport box to rotate and tilt through the support frame, so that the goods can be unloaded quickly. This device does not need to lift the material transport box by hand, which reduces the work intensity of the construction personnel. At the same time, the forward movement of the second wheel can prevent rollover during unloading, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS
