[0026] The pruning machine with adjustable blade angle comprises a frame 1, the frame 1 comprises upright columns 107 arranged on both sides and a cross beam 108 connected with the upper ends of the upright columns 107 on both sides, the lower end of the upright column 107 is connected with a walking wheel set 2, that is, the walking wheel set 2 is symmetrically arranged on both sides of the frame 1 and drives the frame 1 to move.

[0027] The walking wheel set 2 comprises front wheels, rear wheels and a wheel plate fixed at the lower end of the stand column 107, and the front wheels and the rear wheels are rotatably arranged on the wheel plate, so that the frame 1 is stably supported by the walking wheel set 2 on both sides and moves by rotating the front and rear wheels.

[0028] The frame 1 is provided below with a shearing cutter 3, and the two ends of the shearing cutter 3 are connected to the stand columns 107 on both sides of the frame 1 through the lifting push rods 101, so that the two ends of the shearing cutter 3 can be displaced up and down relative to the cross beam 108 on the frame 1; when the lifting push rod 101 on one side drives the end of the shearing cutter 3 on the side to be displaced upward or downward, the shearing cutter 3 can be inclined to one side to adjust the angle of the shearing cutter 3 relative to the frame 1.

[0029] The lifting push rod 101 is an electric push rod, a hydraulic push rod or a pneumatic push rod, and can be matched with a power supply, a hydraulic pump or an air source arranged on the frame 1, so that the lifting push rod 101 is driven by an electric control mode.

[0030] The upper end of the cylinder body of the lifting push rod 101 is provided with a connecting bracket 102, and the stand column 107 of the frame 1 is provided with a fixed bracket 103, and the connecting bracket 102 is rotatably connected with the fixed bracket 103, as shown in Fig. 2 The push rod end of the lifting push rod 101 is rotatably connected with the frame body of the shearing cutter 3, the connecting bracket 102 and the fixed bracket 103 are rotatably connected through a pin shaft 104, the axis of the pin shaft 104 is perpendicular to the cross beam 108 in space, so that when the lifting push rod 101 is stretched or retracted, the shearing cutter 3 can produce a certain floating yaw to avoid interference.

[0031] The frame 1 is provided with a handle 105 for an operator to hold and push the pruner to move forward, and specifically, the handle 105 can be arranged on the stand column 107 on any side, and the handle 105 comprises a handle rod extending upward from the side of the stand column 107 away from the shearing cutter 3, one end of the handle rod is fixedly connected with the stand column 107, and the other end is fixedly connected with the handle body, and the two ends of the handle 105 are used for the operator to hold.

[0032] The control knobs 106 on both sides of the handle 105 are symmetrically arranged and connected with the lifting push rods 101 on the corresponding sides, the control knobs 106 are connected with the lifting push rods 101 through an electric control mode of electric connection, and the control knobs 106 are used for controlling the stretching and retraction of the lifting push rods 101, and specifically, the control knobs 106 are controlled to rotate forward or reverse to make the lifting push rods 101 stretch or retract, so as to control the upward or downward displacement of the shearing cutter 3.

[0033] The rack 1 is provided with a visual level meter for detecting the overall level state of the rack 1 relative to the ground, and an operator can adjust the control knob 106 in time to keep the shearing cutter 3 flat with the end surface of the tea tree under the condition that the two sides of the ground have a difference in height.

[0034] The shearing cutter 3 is a hedge cutter, which comprises a driving unit for driving the shearing cutter 3 to cut transversely, i.e. an internal combustion engine or an electric motor, which is a prior art and will not be described in detail here. The shearing cutter 3 comprises a frame body 301 and a cutter 302 arranged at the front end of the frame body 301. A cover plate 303 is arranged on the upper surface of the side of the frame body 301 away from the cutter 302, and the cover plate 303 and the rack 1 form a door body area 304 for the cut branches to pass through. That is, the cover plate 303 is fixedly arranged on the upper surface of the hedge cutter, and the front end of the cover plate 303 is close to one end of the cutter 302 of the shearing cutter 3.

[0035] In the above embodiment, the door body area 304 is formed by the combination of the cover plate 303, the vertical columns 107 and the cross beam 108 on both sides. The cut branches fall on the cover plate 303 and pass through the door body area 304 so as not to interfere with the rack 1.

[0036] Method for using the pruning machine with adjustable blade angle: the walking wheel sets 2 on both sides are placed on the ground on both sides of the tea tree. When the ground on both sides is at the same level, the cross beam 108 is in a horizontal state, and the shearing cutter 3 can cut the upper surface of the tea tree flatly. When the ground on both sides has a height difference, an operator can observe the level meter and drive the lifting push rod 101 on the side with a lower ground to lift the shearing cutter 3 on the side up so as to keep the shearing cutter 3 flat with the end surface of the tea tree, thereby ensuring the flatness of the tea tree during cutting.

[0037] The cut branches fall on the cover plate 303 through the door body area 304.
