However, mechanical pruning is an important means of shrub forest cultivation and the key to whether shrub forests can develop healthily and sustainably.

[0003] At present, my country's stubble cutting method for bushes is manual felling or using backpack or shoulder-mounted small brush cutters for stubble cutting. This is inefficient and labor-intensive, and cannot meet the requirements of large-scale planting of bushes. This has become a prominent problem restricting the bush planting industry. The existing traction or self-propelled bush harvesters have poor profiling capabilities and cannot solve the problem of harvesting too much sand and gravel at the roots of bushes.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The cantilever work platform 1 of the multifunctional three-dimensional gathering contour cutting table is a mini excavator that can walk among the bushes, and can also be a cantilever work platform with the same function.

[0029] The function of the station conversion mechanism 2 of the multifunctional three-dimensional gathering and profiling cutting table is to convert the cutting positions of the gathering and cutting component 3 and the three-dimensional cutting component 4. The two ends of the steering hydraulic motor 2a are bolted and fixedly connected with the end actuator and the main support frame 2b of the cantilever work platform 1 through the flange 2c.

[0030] The gathering and cutting component 3 in the multifunctional three-dimensional gathering and profiling cutting table is divided into three parts: a lifting device 31, a clamping device 32, and a cutting device 33. The cutting device 33 is fixedly connected to the bottom of the channel steel bracket 31a by bolts. The lifting device 31 is composed of a lifting hydraulic cylinder 31b, a lifting bracket 31c, a chain 31f and a sprocket 31g. Sprockets 31g are installed on both sides of the piston rod of the lifting hydraulic cylinder 31b, and the bottom of the cylinder body is fixed to the slide rail bracket 31a. The chain 31f is wound around the sprocket 31g, and its two ends are respectively fixed on the lifting frame 31c and the fixing plate 31d; the clamping device 32 is fixedly welded on the lifting bracket 31c, and rolling bearings 31e are respectively installed on the sides of the lifting bracket 31c. The lifting bracket 31c is driven by the lifting hydraulic cylinder 31b to reciprocate up and down in the channel steel of the slide rail bracket 31a. The clamping device 32 is composed of a clamping claw driving electric push rod 32a, a supporting bottom plate 32b and a clamping claw 32c. The two ends of the driver 32a are respectively hinged to the ends of the clamping claw 32c, and the clamping claw 32c is hinged to the supporting base plate 32b through a pin shaft. At the same time, a certain gap is left between the two clamping claws to ensure that there is no contact and friction when they move relative to each other. The different opening degrees of the clamping claw 32c are controlled by the driver 32a; the cutting device is composed of a hydraulic motor 33a, a chain saw swing driving electric push rod 33b, a fixed support frame 33c and a chain saw 33d; the hydraulic motor 33a is fixedly installed on the fixed support frame 33c, and the two ends of the chain saw swing electric push rod 33b are respectively hinged to the chain saw 33d and the fixed support frame 33c, and the chain saw swing electric push rod 33b drives the chain saw 33d to swing back and forth with the hydraulic motor 33a as the center.

[0031] The three-dimensional profiling cutting component 4 is composed of a rotating device 41 and a profiling cutting device 42. The function of the rotating device 41 is to support the profiling cutting device 42 and control its rotation speed and rotation angle. The rotating device 41 is composed of a rotating gear 41a, a rack slider 41b, a rotating support shaft 42a, a telescopic electric push rod 41c and a rotating support base plate 41d. The end of the rotating support shaft 42a is spline-connected with the rotating gear 41a, and the rotating gear 41a and the rack slider 41b are meshed and transmitted to form a gear rack transmission mechanism; the rack slider 41b is welded by a rack and a square slider, and is connected to the rotating support base plate 41d through a telescopic electric push rod 41c; the telescopic electric push rod 41c drives the rack slider 41b to slide horizontally along the U-shaped slide groove of the rotating support base plate 41d.

[0032] like Figure 7 As shown, rectangular notches are cut out on the sides of the square support frame 42b, and the top thereof is fixedly connected to the rotating support shaft 42a by bolts; the amplitude adjustment electric push rod 42c is embedded in the square support frame 42b, one end of which is hinged to the inner wall of the square support frame 42b by a pin, and the two sides of the other end are respectively hinged to the connecting support rod 42j. The two ends of the motor support connecting rod 42d and the long connecting rod 42i are respectively hinged to the square support frame 42b and the L-shaped supporting connecting rod 42h to form a parallel four-bar mechanism, which are respectively located on both sides of the square support frame 42b in a rotationally symmetrical distribution. The motor 42e is fixedly mounted on the motor support connecting rod 42d, and the motor 42e controls the rotation speed of the contour cutting tool 42f.

[0033] The operator can control the actions of each hydraulic cylinder and electric push rod by operating the corresponding solenoid valve or switch on the operating console. The clamping claw drives the electric push rod 32a to control the opening degree of the clamping claw 32c; the clamping device 32 is driven to slide up and down along the channel steel of the slide rail bracket 31a by lifting the hydraulic cylinder 31b; the chain saw 33d is driven to swing back and forth around the hydraulic motor 33a by controlling the swing of the chain saw electric push rod 33b; the profiling cutting device 42 is driven to reciprocate by the telescopic electric push rod 41c; the profiling cutting tool is driven to swing back and forth relative to the square support frame 42b by the amplitude adjustment electric push rod 42c to adjust the profiling cutting radius.

[0034] The operating state of the multifunctional three-dimensional gathering and profiling header is described below:

[0035] like Figure 8As shown, in the working state, the positioning hole 41f of the rotating support bottom plate of the multifunctional three-dimensional gathering and profiling cutting table and the positioning hole 31j of the channel steel bracket 31a are fixedly connected by the positioning pin 41g, so that the gathering and cutting component 3 and the three-dimensional profiling cutting component 4 are unfolded in an "L" shape. After the control console 5 makes the gathering and cutting component 3 complete the cutting action, the steering mechanism 2 rotates 90 degrees, so that the gathering and cutting component 3 and the three-dimensional profiling cutting component 4 exchange positions; Fig.10 As shown, while the three-dimensional profiling cutting component 4 is profiling, the gathering cutting component 3 places the cut bushes 6 on the side of the multifunctional three-dimensional gathering profiling cutting table, and reciprocating cutting is performed in this way.

[0036] When the operation is completed, the lower positioning hole 41h of the rotating lower support frame is fixedly connected to the channel steel bracket 31a through the positioning pin, so that the gathering cutting component 3 and the three-dimensional contour cutting component 4 are folded parallel to each other.
