Four-wheel copy foldable land leveler

Abstract

The invention relates to a bulldozing or scraping device, in particular to a four-wheel copy foldable bulldozing and scraping shovel. The device comprises a main scraping shovel and breast boards installed at both ends of the main scraping shovel. The four-wheel copy foldable land leveler is characterized in that both ends of the main scraping shovel are connected with an assistant bulldozing and scraping shovel through a hinge. The main and assistant bulldozing and scraping shovels are fixedly connected through bolts. The breast boards are installed at both ends of the assistant bulldozing and scraping shovels. A traction frame is connected on the back of the main scraping shovel through a hinge, and an angle adjusting device is installed between the main scraping shovel and the traction frame. One end of the frame is hinged with the traction frame while the other end of the frame is fixedly provided with a connecting base. The middle part of the copy wheel fixing shaft is installed on the connecting base in a swinging manner. The middle parts of copy wheel fixing plates are installed at both ends of the copy wheel fixing shaft. Wheels are respectively arranged at both ends of the copy wheel fixing plates. The four-wheel copy foldable bulldozing and scraping shovel adopting the technical scheme is reasonable in structure and convenient to use, overcomes the defects in the prior art, and is extremely suitable for leveling construction of land surface.

Description

technical field [0001] The invention relates to a device for bulldozing or scraping soil, in particular to a four-wheel profiling foldable grader. Background technique [0002] At present, the width of the scraper or bulldozer on the bulldozer or other bulldozing or scraping equipment is fixed. Due to the different geological conditions, especially the different hardness and strength of the soil, on the one hand, it can only be passed through Adjust the depth of the scraper or bulldozer to adapt to the power of the bulldozer. On the other hand, it will cause unevenness in height after repeated bulldozing or scraping. At the same time, due to the undulation of the ground, it will cause bulldozing. Or the scraping soil is too deep or too shallow. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and to provide a four-wheel profiling foldable motor grader which can easily adjust the width of the...
