The invention discloses a vertical dust collector, and aims to provide a vertical dust collector capable of improving the assembly efficiency and stability and enhancing the heat dissipation efficiency. The dust collector comprises a dust collecting box which is connected with rollers; the mounting seat is detachably connected with the dust collection box, and an air inlet is formed in the mounting seat; the ventilation net rack is connected with the mounting base, one side of the ventilation net rack is detachably connected with a dust filtering cup assembly, and the other side of the ventilation net rack is detachably connected with a dust collection motor; the connecting assembly is connected with the mounting seat; the motor cover is provided with an air outlet, and the mounting seat is provided with an air outlet channel; the box cover, the motor cover and the box cover are respectively provided with a heat dissipation opening, and the box cover is rotationally connected with a handle. The dust collector has the beneficial effects that the cleaning capacity of the dust collector is improved; the assembly efficiency of dust collector accessories is improved; disassembly and maintenance are convenient, and moving and using are convenient; the heat dissipation performance and the dustproof effect are enhanced; the cleaning time and the service life are prolonged; the overall strength is improved.

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.
