Problems solved by technology
[0002] Existing small excavators generally use multiple booms to control the movement of the bucket, and most of the booms are controlled by a hydraulic control system, which requires high manufacturing precision of hydraulic components, strict assembly requirements, and relatively difficult maintenance and repair. Difficult, life expectancy is not ideal
The viscosity of working oil is greatly affected by temperature, so working at high temperature and low temperature will affect the transmission efficiency
In addition, the leakage of oil will also affect the smooth operation and transmission efficiency.

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] The first embodiment, such as figure 1 As shown, the bucket of the present invention has a single-lever excavation mechanism with a booster mechanism, including a frame base 17, a bucket 1, and a power arm 14, and the right side of the frame base 17 is fixed with a power arm support seat 12 and a push arm support seat 16. One end of the power arm support base 12 and the power arm 14 is hinged through the reaming hole II13 of the power arm support base, and the other end of the power arm 14 is hinged with the connector II23 fixed on the bucket 1 through the reaming hole 22 of the connector II , the upper side of the power arm 14 is provided with a guide rail that cooperates with the slider Ⅰ7, and the slider Ⅰ7 can move forward and backward on the guide rail. The hinge is formed through the reaming hole I5, the other end of the rod I4 is connected with the conne...

The invention discloses a single pole excavation mechanism with a bucket provided with a force-amplifier. The single pole excavation mechanism is characterized in that a power arm supporting seat and a pushing arm supporting seat are fixed to the same side of a base; the power arm supporting seat is hinged to a power arm, and the other end of the power arm is hinged to the bucket; a guide rail matched with a sliding block is arranged on the upper side of the power arm, the sliding block is hinged to two rods respectively, the other end of one rod is fixedly connected with the bucket through a hinged rod piece, and the other end of the other rod hinged to the sliding block is hinged to the power arm supporting seat through a hinged rod piece; the middle of the lower side of the power arm is hinged to a lower power arm, the other end of the lower power arm is hinged to a pushing arm, and the other end of the pushing arm is hinged to the pushing arm supporting seat; the pushing arm and a rod piece hinged to the power arm supporting seat are driven by stepped motors respectively to do small-amplitude rotation. According to the single pole excavation mechanism, the excavating capacity and lifting capacity of the bucket can be enhanced through the force-amplifier, so working requirements can be met just by utilizing a single arm and hydraulic drive is not needed.
Description
technical field [0001] The invention relates to an excavating mechanism, in particular to a single-rod excavating mechanism with a bucket having a booster mechanism. Background technique [0002] Existing small excavators generally use multiple booms to control the movement of the bucket, and most of the booms are controlled by a hydraulic control system, which requires high manufacturing precision of hydraulic components, strict assembly requirements, and relatively difficult maintenance and repair. Difficult, life expectancy is not ideal. The viscosity of working oil is greatly affected by temperature, so working at high temperature and low temperature will affect the transmission efficiency. In addition, the leakage of oil will also affect the smooth operation and transmission efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-lever excavation mechanism with a booster mechanism for the buck...
