2results about How to "Low operating noise" patented technology

The present disclosure relates to the technical field of transmission mechanism, and provides a reciprocating motion device and electronic equipment. The former comprises a driving motor, a winding wire, a rotating member and a connecting member. The driving motor has an output shaft. Two ends of the winding wire are wound on the output shaft in two opposite directions. The rotating member is arranged in correspondence with the output shaft at intervals, and the winding wire is tightly wound around the circumference of the rotating member. The connecting member is fixedly connected with the winding wire. Under the working condition of driving the output shaft to rotate forward or reverse by the driving motor, one end of the winding wire can increase the winding length, and the other end can decrease the winding length, so that the winding wire reciprocally slides around the circumference of the rotating member, and drives the connecting member to reciprocate. The latter comprises the former, and both can flexibly switch and change the motion direction of the connecting member and the workpiece by forward and reverse rotation of the driving motor, and have the beneficial effects of compact structure, low requirement for installation space size, and low operation noise.

The utility model discloses electric drive caterpillar type corn harvester, including harvester body and chassis, the middle part of chassis is equipped with engine and generator, and the transmission connection through the belt between engine and generator, the bottom symmetry of chassis is equipped with caterpillar walking mechanism, and the bottom of chassis is equipped with the first drive motor for driving caterpillar walking mechanism, and the front side of chassis is equipped with cutting platform mechanism, and the front side of harvester body is equipped with the second drive motor for driving cutting platform mechanism, and the middle part of harvester body is equipped with stripping, hoisting mechanism, and stripping, hoisting mechanism is equipped with the third drive motor for driving stripping, hoisting mechanism. Through above -mentioned structure, through diesel engine drive generator is charged for battery group, and by battery group preferentially for independent control's drive motor, power supply, realizes walking, ear picking, peeling and hoisting etc. The accurate power distribution of work link, compared with traditional diesel engine type, is more energy -conserving and environment -friendly, and the operation noise is low.
