detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 to FIG. 3, a rotary tiller includes a fixed bracket 1, a fixed baffle 2, a fixed block 3, a nut 4, a movable rod 5, a joint 6, a universal joint 7, and a sub-transmission box 8. , connecting rod 9, machete 10, rotation a crusher 11, a main drive shaft 12, a plowshare 13, a rake 14, a shovel 15, and a rotary cultivator body 16; the fixed bracket 1 is fixedly coupled to the cultivator body 16; 2 is mounted on the rotary tiller body 16; the fixed block 3 is disposed at one end of the connecting rod 9; the nut 4 is disposed on the fixed block 3; the movable rod 5 is coupled to the fixed bracket 1 and the rotary tiller body 16 The sub-transmission box 8 is evenly distributed on the connecting rod 9; the machete 10 is mounted on the rotating shovel 11; the main transmission shaft 12 is disposed inside the connecting rod 9; A pryder 13 is installed below the tank 8; the rake 14 is provided at one end of the connecting rod 9; and the shovel 15 is mounted at the lowermost end of the fixed baffle 2.

As a precaution for the use of the present invention: the start of the operation, the rotary tiller should be in a raised state, first combined with the power output shaft, the cutter shaft speed is increased to the rated speed, and then the rotary tiller is lowered to gradually insert the blade into the desired depth. It is forbidden to combine the power output shaft or the sharply descending rotary tiller after the blade is put into the soil, so as not to cause the blade to bend or break and increase the load of the tractor; in the operation, it should be slowed down as low as possible, so as to ensure the quality of the work and make the clods fine. It can also reduce the wear of the machine. Pay attention to whether the rotary tiller has noise or metal knocking sound, and observe the soil and depth of the soil. If there is any abnormality, stop it immediately and check it. If it is excluded, continue the operation. When turning the ground, prohibit the operation. Raise the rotary tiller to make the blade leave the ground and reduce the throttle of the tractor to avoid damage to the blade. When raising the rotary tiller, the inclination angle of the universal joint operation should be less than 30 degrees. When it is too large, it will produce impact noise, which will cause premature wear or damage. When reversing, overpassing and transferring the plot, the rotary tiller should be used. Lift to the highest position and cut off the power to avoid damage to the machine. If it is transferred to a distant place, the rotary tiller should be fixed with a locking device; after each shift, the rotary tiller should be maintained.
