[0010] Preferably, the movable shaft is threadedly connected to the turntable via a connecting disk, and the rotary tillage blades are distributed at equal intervals on the outside of the movable shaft.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The crawler rotary tiller that can be raised and lowered is used in coordination with a support rod, a hydraulic cylinder, a hydraulic rod, a rotating shaft, a movable arm and a soil retaining cover. When the height of the rotary tiller blade needs to be adjusted, the hydraulic rod is driven to extend and retract by turning on the switch of the hydraulic cylinder, and one end of the movable arm is driven to rotate around the rotating shaft by the hydraulic rod, thereby driving the rotary tiller blade to be raised and lowered. The height of the rotary tiller blade can be adjusted according to different operation requirements, so that the rotary tiller body can adapt to different soil and terrain conditions, thereby improving the application range of the rotary tiller body;

[0013] 2. This kind of liftable crawler rotary tiller is equipped with a turntable, fixing bolts, a connecting plate, a movable shaft and a rotary tiller blade. When the rotary tiller blade is prone to wear or even damage after being used for a period of time, the turntable and the connecting plate can be separated by unscrewing the fixing bolts, so that the movable shaft can be removed from the inside of the soil retaining cover to maintain and replace the rotary tiller blade. The disassembly structure is relatively simple, ensuring the working efficiency of the rotary tiller body. BRIEF DESCRIPTION OF THE DRAWINGS

The movable arm 6 forms a rotating structure with the rotary tiller body 1 through the rotating shaft 5. The movable arms 6 are symmetrically arranged with the central axis of the rotary tiller body 1. The soil retaining cover 7 is supported by two groups of movable arms 6 to ensure the structural stability of the device. A soil retaining cover 7 is fixed below one side of the movable arm 6. The soil retaining cover 7 is a semicircular structure. The soil retaining cover 7 is fixedly connected to the movable arm 6.
