Problems solved by technology
Manual bulldozers are labor-intensive and low in efficiency; horizontal electric bulldozers are complex in manufacturing process, occupy a large area, and have a high gear failure rate; the hydraulic rods of electrohydraulic bulldozers are easily eroded by chemical components in the soil. It is easy to enter the hydraulic cycle, difficult to clean and cause damage to the oil pump, which will have a great impact on its normal use

The invention discloses a multi-link-type electric bulldozing device, which comprises a supporting and control part, a reaction frame part and a power part. In the supporting and control part, a supporting frame is an equipment load-bearing main body, and a digital controller is located on the supporting frame and connected with a power supply through a wire; in the reaction frame part, four supporting frames are fixed to the four corners of the supporting frame face, two square plates are fixed to the four supporting frames, and fixing rings are arranged at center holes in the inner sides ofthe two square plates correspondingly; and in the power part, a motor is fixed to the supporting frame face and connected with the digital controller through a wire, one of pushing rods is directly connected with the motor to obtain power, the other four pushing rods are connected with the last pushing rod through power transmission pieces to obtain the power, and jacking heads are connected to the upper ends of the pushing rods correspondingly. The invention provides a multi-link-type electric bulldozing method. The experimental efficiency is effectively improved, steps are simplified, the consumed time is reduced, and operation and maintenance are easy.
Description
technical field [0001] The invention relates to a multi-connection electric bulldozer for taking out undisturbed soil samples, in particular to a thin-wall bulldozer and a bulldozing method for efficiently taking out undisturbed soil suitable for different types of sample cylinders. Background technique [0002] In the field of geotechnical experiments, undisturbed soil has been widely used because it maintains the natural moisture content and natural structure, and can more truly reflect the physical and mechanical properties of natural soil such as weight, permeability coefficient, compressibility coefficient and shear strength; The retrieved soil samples are usually sealed and stored in different types of sample cylinders to maintain their moisture content, and the soil samples are taken out by bulldozers as needed during the experiment. [0003] In some experiments that require a large number of undisturbed soil samples, in order to improve the experimental efficiency, t...
