The invention is composed of an input shaft, an output shaft, some center shafts and some clutches and gears, wherein some gears form a reversing gear set, the other gears form a driver gear set, the input shaft and the second, sixth center shafts seen from end show triangle arrangement according to the transmission route of axes, the input shaft and the first, second, sixth middle shafts show quadrilateralarrangement, the output shaft and the third, fouth, fifth center shafts show quadrilateral arrangement. The transmission route of the structure is more compact, using less spares, high transmission efficiency.

The invention provides a flying car, which has the function of four-wheel independent electric drive, and includes a chassis, a wheel propeller assembly installed on the chassis, and an overturning mechanism assembly. The belt brake is used to control the planetary gear mechanism to realize the hub motor to drive the wheel or propeller to rotate. The turning mechanism assembly can be used to turn the wheel propeller assembly vertically or parallel to the ground. When switching between car mode and flight mode, the planet carrier or the wheel can be fixed by controlling the tightening of the brake band of the planet carrier or the ring gear, so that the output power of the hub motor can be transmitted to the wheel or the propeller shaft , to enter car mode or airplane mode. In addition, the propeller blades can be retracted under the action of the return spring, which is convenient to be integrated with the wheels. It can perform in-situ vertical lift and fly smoothly without affecting other vehicles, and at the same time, it can also improve the problem of poor passability of existing vehicles.

The dynamic power shifting transmission has the advantages as follows: the gears are rather plentiful, the speed ratio is reasonable and the operation is simple and convenient.

The invention discloses a chassis of multifunctional agricultural management machine. A guiding wheel axle which is parallel with a front cross beam is arranged in front of the front cross beam. The front cross beam is provided with two side plates which are bilaterally symmetrical. A container front installing tube is connected between the upper ends of the two side plates. Two oil cylinder support plates which are parallel on left and right are arranged between the two side plates. A gearbox is arranged on a gearbox supporting plate. The gearbox is provided with two output ends which are symmetrical on left and right. Each output end is connected with an output axle shaft. The output axle shaft is provided with a driving wheel. The driving wheel is connected with the guiding wheel on the same side through a crawler belt. A plurality of track rollers are arranged from front to back between the driving wheel and the guiding wheel which are on the same side. The chassis is simple and compact in structure, small in volume, and low in production cost. On one hand, the chassis is beneficial for arrangement and installation for other functional components, and the chassis can carry a large volume container, effectively improving carry capacity, on the other hand, the crawler belt is used to travel, so passing ability is good, gradeability is good, and the chassis does not hurt earth's surface and vegetation.

The invention discloses a reciprocating chain drive mechanism, which comprises a push rod (3) and a push head (4) connected with the push rod. The push rod slides in a slideway (12), and also includes a The driving device (6), the driving device is adjacent to the slideway, and the driving device rotates regularly to drive the push rod to reciprocate back and forth. When the push head on the push rod moves forward with the push rod, the push head and the process The contact of the block on the car drives the craft car to move forward; when the push head on the push rod moves backward with the push rod, the push head touches the next stop, and the push head crosses the stop and automatically resets, so as to repeatedly realize the craft car Intermittent forward movement. The present invention adopts the driving device to convert the positive and negative rotation of the motor into the forward and backward movement of the push rod, and then realizes the linear intermittent forward movement of the craft car through the action of pushing the head on the push rod; Short, less transmission parts, no need to mine a large foundation to meet the rotation, occupying a small space, and simple structure.
