Problems solved by technology
However, the connecting rod combined dump truck also has defects. Because the amplifying mechanism takes up a lot of space, the center of gravity of the dump truck is relatively high, which affects the driving stability and lifting stability of the dump truck.

The invention discloses a self-dumping overturning device. One end of the bottom of a storage box of the self-dumping overturning device is connected to a machine frame through a first revolute pair; the upper end of a first connecting rod is connected to the bottom of the storage box through a second revolute pair; the lower end of the first connecting rod is connected with the upper end of a second connecting rod through a fourth revolute pair; the lower end of the second connecting rod is connected onto the machine frame through a fifth revolute pair; a motor is fixed to the machine frame; the output shaft of the motor is connected with one end of a threaded screw; the other end of the threaded screw is mounted inside the lower end of an internal threaded tube; the upper end of the internal threaded tube is connected onto the first connecting rod through a third revolute pair. The self-dumping overturning device can use a lifting cylinder with a shorter stroke to obtain large-angle lifting, occupies a smaller space, can lower the gravity center of a self-dumping truck, improves the driving stability and the lifting stability of the self-dumping truck, and can overturn a skip bucket of the truck through smaller power.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a self-unloading turning device. Background technique [0002] Dump trucks are classified according to the lifting type, generally divided into direct push type and connecting rod combination type. The connecting rod combination is composed of a lifting cylinder and a set of pull rods, triangle arms and other amplification mechanisms. The so-called amplification mechanism means that a short-stroke lifting cylinder can be used to obtain a large-angle lift through this mechanism. The connecting rod combined dump truck is more favored by users because of its cheap price and good lifting stability. However, there are also defects in the connecting rod combined dump truck. Because the amplifying mechanism takes up a large space, the center of gravity of the dump truck is relatively high, which affects the driving stability and lifting stability of the dump truck.
