Example Embodiment

[0017] In order to make the object, structure and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0018] like Figure 1-Figure 2 As shown, the present invention is realized by adopting the following technical solutions: a tiller includes a frame 1 , a handrail frame 4 , a supporting wheel 2 and a traveling wheel 3 . The support wheel is located at the front, and its diameter is smaller than that of the traveling wheel. It is used as a traveling front wheel when it is not working, and it is mainly used as an adjustment device to limit the depth of ploughing when it is working. The support wheel is connected to the cylinder 21 fixed above the frame through the screw 11, the cylinder is provided with an internal thread, the screw is penetrated in the cylinder, and the top of the screw is provided with a rotating handle 22. There are two traveling wheels, which are connected by a fixed shaft 12 . The supporting wheel and the traveling wheel are distributed in an isosceles triangle. Below the frame part in this isosceles triangle there is a Y-shaped frame 7, one corner of the frame facing the rear of the support wheel. Ploughshares 9 are arranged on the three corners of the Y-shaped skeleton. The plowshare tip is forward. For the convenience of adjusting the height of the ploughshare, there is a cross lift rod 8 in the center of the frame. Cross lift bars are provided throughout the rack. Its crossbar section is above the rack. In order to fix the cross bar 11, the upper surface of the frame is provided with a placement groove 19 which is matched with the cross bar. Inside the placement groove 19 is a lift rod through hole 24 that is convenient for the lift rod to pass through. A rack table 10 is provided above the placement groove, and a cross bar through hole 23 for the cross bar to pass through is provided on the rack table. At the same time, a placement groove 19 is also provided on the upper surface of the rack table. The placement groove 19 intersects the cross bar through hole 23 .
[0019] A group of rotary tiller wheels 13 are also arranged at the rear of the frame, and these rotary tiller wheels are connected in series on the same main shaft 14 in parallel. Both ends of the main shaft 14 are movably connected with the fixed shaft 12 through a connecting rod 15 , a hanging rod 16 is provided in the middle of the main shaft, and a hook 17 is provided at the other end of the hanging rod. The hook 17 can be hung on the hook groove 18 on the vertical rod 5 of the armrest frame. In order to ensure that the center of gravity of the tiller always falls in the isosceles triangle area, the motor 6 is fixed above the Y-shaped frame.
[0020] Further, at least two hook grooves are provided.
[0021] Further, the hook grooves are arranged in parallel on the vertical rod from top to bottom, and the positions of the hook grooves are different. When the hooks are hung in the hook grooves at different positions, the height of the rotary tiller wheel is also different.
[0022] Further, a guard plate 25 is provided behind the rotary tiller wheel and the traveling wheel.
[0023] In the present invention, when walking, the hook can be hung in the hook groove, thereby lifting the rotary tiller wheel, and at the same time, the cross lifting rod is lifted until the cross rod passes through the through hole of the cross rod, the lifting rod is rotated, and the horizontal rod is placed in the placing groove to be fixed. That is, the plowshare can be lifted, and only the supporting wheel and the walking wheel fall on the ground at this time, so that the walking can be carried out smoothly and easily.
[0024] When ploughing is to be carried out, hang the hook in the hook groove of the lowest level, and place the cross bar in the placing groove on the frame, so that the rotary tiller wheel and the plowshare both fall on the ground. At the same time, the rotary handle is rotated to control the lifting and lowering of the screw, thereby controlling the height of the support wheel, and the height from the bottom of the support wheel to the ground is the plowing depth.
[0025] Of course, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention, and the present invention is not limited to the above examples. Modifications, additions or substitutions also belong to the protection scope of the present invention.
