Problems solved by technology

[0002] At present, tractors are mainly used for field work. However, tractors have certain defects in field work: the ground clearance is low, and high-stem crops are easily damaged during field work; generally, different application environments have different requirements for vehicle clearance. For example, weeding, fertilization, transplanting, and pesticide application, etc.; and different growth periods of crops have different requirements for vehicle clearance, so in order to be able to complete common routine ope

Embodiment Construction

[0010] The present invention will be further described below with reference to the drawings and specific embodiments.

[0011] Such as figure 1 As shown, an automatic lifting drive axle is composed of a transmission device and a lifting device. The transmission device transmits power to the wheels of the vehicle to drive the vehicle to walk; the lifting device controls the height of the bridge body from the ground, thereby continuously controlling the vehicle drive axle The ground clearance height.

[0012] Such as figure 1 As shown, the transmission device includes a bridge body 8, a bridge tube 6 on both sides of the bridge body, a power output shaft 7 in the bridge tube, an upper case 3 on both sides of the bridge tube, and an upper meshing master-slave in the upper case 3 Moving bevel gears 4 and 9, spline tube 11, lower case 14 on both sides of the bridge tube, lower meshing driving and driven bevel gears 15 and 16 in the lower case, wheel axle 18 and upper and lower bearing...

Abstract

The invention belongs to the field of agricultural machinery, and particularly relates to an automatic lifting drive axle. The drive axle comprises a transmission device and a lifting device, wherein the transmission device transfers power to wheels of a vehicle, and drives the vehicle to run, and the lifting device controls the ground height of an axle body, so as to continuously control the ground clearance height of the drive axle of the vehicle. The drive axle can adjust a ground clearance according to operating conditions and different crop growth periods, and is large and continuous in adjustable range, and convenient and reliable in adjustment. Furthermore, the drive axle is compact in structure, large in transmission ratio and large in torque; an application range of an agricultural machine is widened; and a use ratio of the agricultural machine is increased.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery, and particularly relates to an automatic lifting drive axle. Background technique [0002] At present, the machinery used for field operations is mainly tractors, but tractors used for field operations have certain defects: low ground clearance, high-stalk crops are easily damaged during field operations; generally, different application environments have different requirements for vehicle ground clearance. For example, weeding, fertilization, transplanting, and pesticide application; and different growth periods of crops have different requirements on the vehicle ground clearance, so in order to be able to complete ordinary routine operations and mid- to late-stage management operations in the field, different agricultural machinery needs to be configured, not only a large investment Moreover, the equipment utilization rate is low; Chinese invention patent ZL201110321470.4 discloses a high groun...
