Metamorphic mechanism type dumping excavator

Abstract

The invention discloses a metamorphic mechanism type dumping excavator. A first sliding groove of the excavator is welded on a shell, a driving crank is connected with the shell through a first pin shaft and is mainly used for being flexibly positioned, the metamorphism of a second metamorphic rod is facilitated, a third sliding groove is welded on the shell, an eleventh connecting rod is connected with a twelfth connecting rod through a nineteenth pin shaft, the twelfth connecting rod is connected with a second connecting rod through a twentieth pin shaft, is mounted in the third sliding groove and can move along the third sliding groove, and the second connecting rod is connected with a rotary block through a fifth pin shaft. The excavator has the advantages that the periodic motion locus of the mechanism can be changed through the metamorphism of the mechanism, so that the mechanism has both an excavating function and a dumping function, the functions of the excavator are improved, an idea of changing the periodic motion locus of the mechanism by using the metamorphic mechanism is transferred more importantly, and the metamorphic mechanism is applied more widely.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a metamorphic mechanism type excavator capable of discharging soil. Background technique [0002] In recent years, with the development of society, industries such as construction and planting have also attracted people's attention. In these industries, excavation is an indispensable link, so the design of excavators has also attracted people's attention. At present Most of the excavators in China are large-scale excavators, and most of them dig soil in the form of auger drilling soil. This form is only suitable for digging deep soil, not suitable for digging pits with relatively large diameters and It is not easy to discharge soil. Chinese patent 201310145359.3 discloses a hand-held excavator. The excavator digs soil in a spiral manner. The diameter of the excavation pit is small and it is not easy to discharge soil. Therefore, it is necessary to design a portable excavator tha...

[0002] In recent years, with the development of society, industries such as construction and planting have also attracted people's attention. In these industries, excavation is an indispensable link, so the design of excavators has also attracted people's attention. At present Most of the excavators in China are large-scale excavators, and most of them dig soil in the form of auger drilling soil. This form is only suitable for digging deep soil, not suitable for digging pits with relatively large diameters and It is not easy to discharge soil. Chinese patent 201310145359.3 discloses a hand-held excavator. The excavator digs soil in a spiral manner. The diameter of the excavation pit is small and it is not easy to discharge soil. Therefore, it is necessary to design a portable excavator that is convenient for soil discharge and flexible in operation.

[0003] At present, there is no innovative invention design of a portable excavator that can not only quickly excavate the soil but also facilitate the discharge of the soil.
