[0028] In this embodiment, the machine body 1 includes a flat plate 101, a connecting plate 102 fixed to the rear side of the flat plate 101, and a handle 103 detachably connected to the connecting plate 102 via a pin; the power unit 2 is located on the front side of the flat plate 101, and the walking wheel set 3, rotary tiller 4, and ditching blade 5 are arranged sequentially from front to back below the flat plate 101; the power unit 2 includes an engine 21 and a gearbox 22 fixedly mounted on the flat plate 101, the output shaft of the engine 21 is poweredly connected to the input shaft of the gearbox 22, and the output shaft of the gearbox 22 is connected to the walking wheel set 3 via a transmission assembly.

[0029] Specifically, the engine 21 can be configured as a gasoline engine 21, a diesel engine 21, a kerosene engine 21, or a gasoline-to-diesel engine 21; the wheel set 3 includes an axle 31, which is rotatably connected to the front bottom of the flat plate 101 through multiple axle plates, and a running wheel 32 is fixedly installed on both sides of the axle 31; the two ends of the transmission assembly 1 are respectively connected to the output shaft of the gearbox 22 and the axle 31, and the transmission assembly 1 can be configured as a belt drive or a chain drive.

[0030] The rotary tiller 4 includes a blade shaft 41 rotatably connected to the height adjustment mechanism 6. The outer wall of the blade shaft 41 is provided with multiple sets of blades 42 along the axial direction. Each set of blades 42 includes multiple blades 42 that are uniformly fixed along the circumference of the blade shaft 41.

The two ends of the transmission component 2 are connected to the first cutter shaft 41 and the second cutter shaft 51 respectively. The transmission component 2 can be a chain drive or a belt drive.

[0032] Using this scheme, the rotary tiller 4 can first loosen the soil and crush hard objects such as roots in the soil, and then the trenching blade 5 can be used to open trenches in the soil, which improves the efficiency and convenience of trenching.

[0033] Further optimize the plan, such as Figure 3 As shown, the height adjustment mechanism 6 includes a mounting frame 61, with rotary tillers 4 and furrowing blades 5 connected to the mounting frame 61 respectively; multiple vertically arranged guide rods 62 are connected to the mounting frame 61, and the tops of the multiple guide rods 62 slide upward through the machine body 1 and are connected to a connecting frame 63; a drive assembly 64 is provided on the machine body 1, and the drive assembly 64 drives the connecting frame 63 to move vertically.

The top of the four guide rods 62 are fixed together with a connecting frame 63.

[0035] Using this scheme, the drive component 64 drives the connecting frame 63 to move vertically. The connecting frame 63 drives the guide rod 62, the mounting frame 61, the rotary tiller 4, and the ditching blade 5 to move vertically as a whole, thereby achieving the effect of adjusting the height of the rotary tiller 4 and the ditching blade 5, and thus adjusting the depth of rotary tillage and ditching.

[0036] Further optimize the plan, such as Figure 4As shown, the drive assembly 64 includes a plurality of parallel and spaced vertical rods 641. The top of the vertical rods 641 is fixedly connected to the connecting frame 63, and the bottom abuts against the inclined surface of the drive block 642. The drive block 642 is slidably connected to the body 1 and is connected to the moving end of the horizontal drive component 643. The horizontal drive component 643 is connected to the body 1 through a mounting base. The bottom of the drive block 642 is slidably connected to the guide rail 644, and the guide rail 644 is connected to the body 1.

[0037] In this embodiment, each vertical rod 641 corresponds to a driving block 642, and the driving blocks 642 are connected as a whole by a fixing rod; each driving block 642 corresponds to a guide rail 644, and the guide rail 644 is fixed on the plate 101; the horizontal driving component 643 can be configured as a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, the fixed end of the horizontal driving component 643 is fixed on the plate 101 by a mounting seat, and the moving end of the horizontal driving component 643 is fixedly connected to the fixing rod.

[0038] By controlling the horizontal drive component 643 and extending or shortening its moving end, the drive block 642 can be driven to move horizontally in a straight line via the fixed rod. Through the inclined surface of the drive block 642 and the vertical rod 641, the connecting frame 63 can be moved vertically.

[0039] Further optimize the plan, such as Figure 4 As shown, a baffle plate 8 is fixed to the rear side of the mounting frame 61. In this embodiment, the baffle plate 8 is arc-shaped, which can block soil clods that fly up during rotary tillage and ditching.

[0040] Further optimize the plan, such as Figure 5 As shown, the tensioning mechanism 7 includes a vertical drive component 71 connected to the body 1. A tensioning wheel 72 for tensioning a chain or belt is connected to the actuating end of the vertical drive component 71.

During the process, the vertical drive component 71 cooperates to drive the wheel body 722 to move. When the height is adjusted to the correct position, the vertical drive component 71 drives the wheel body 722 to tension the chain or belt.

[0042] Further optimize the plan, such as Figure 5 As shown, guide plates 73 are fixedly connected to both sides of the wheel frame 721. Vertically arranged guide posts 74 slide through the guide plates 73. The top of the guide posts 74 is connected to the body 1, and the bottom is connected to a limit plate 75.
