Description

Rotary knife tree pruning machine

technical field

The utility model relates to a pruning machine, in particular to a rotary knife type arbor pruning machine.

Background technique

When pruning a tree, it is mainly carried out with the help of a ladder and a saw, or it is mainly carried out by people climbing up the trunk. This operation method needs to adjust the position and go up and down many times to complete. The pruning speed is slow, time-consuming and laborious. The efficiency is low, and the risk factor is relatively high. When the operator is operating on the ladder, because it is a high-altitude operation, sometimes the operator will fall off the ladder. Because of these reasons, people sometimes simply give up the high-altitude pruning, which has a great impact on the pruning shape and the growth of the main trunk for pruning side branches, reducing the economic benefits of trees.

Utility model content

The purpose of the utility model is to provide a rotary knife type arbor pruning machine, which is more convenient, fast and safe when pruning trees.

In order to achieve the above object, the utility model adopts the following technical scheme: the rotary knife type arbor pruning machine includes a driving part and a lifting frame, the driving part is provided with a vertical and horizontal two-way driving device, and the lifting frame is a scissor type lifting frame The upper end of the lifting frame is provided with a main bracket, and the main bracket is provided with a power system and a shearing system. The shearing system includes a rotary cutter head and a cutter bar vertically arranged on the outer circumference of the rotary cutter head, and the rotary cutter The disk is connected with the power system transmission, and the center of the rotary cutter head is provided with a contact sensor, which is connected with the control system of the rotary cutter head.

The power system includes a generator and a stepping motor, the generator is electrically connected to the stepping motor, the stepping motor is provided with a control system for the rotary cutterhead, and the stepping motor is connected to the rotary cutterhead through transmission.

The rotary cutterhead is arranged horizontally, the stepping motor is arranged vertically, and the output shaft of the stepping motor is connected to the center of the rotary cutterhead.

The shearing system is fixed by a support plate and a support base.

The utility model saves time and labor, is safer and more reliable, and greatly reduces labor intensity, improves pruning efficiency, and is suitable for pruning tall trees on both sides of urban streets and highways.

Detailed ways

Embodiment: as shown in Figure 1, 2, rotary knife type arbor pruning machine, comprises driving part 1 and lifting frame 2, and driving part is provided with vertically and horizontally two-way driving device, and lifting frame 2 is a scissor type lifting frame; The upper end is provided with main bracket 18, and main bracket 18 is provided with generator 11, stepping motor 3 and shearing system, and stepping motor 3 is arranged on the motor supporting base 12, and shearing system includes rotary cutter head 7 and vertical The cutter bar 9 arranged on the outer circumference of the rotary cutter head 7 is fixed by the cutter bar bolt hole 13 provided on the rotary cutter head 7 , the rotary cutter head 7 is connected with the stepper motor 3 through transmission, and the center of the rotary cutter head 7 A contact sensor 8 is provided, and the contact sensor 8 is arranged on the sensor support seat 14 (the two are threaded connections), and the bottom flange of the sensor support seat 14 and the shaft end retaining ring 17 and the support plate 6 are consolidated together with bolts 16, The contact sensor 8 is connected to the control system of the rotary cutter head 7 . Generator 11 is electrically connected with stepper motor 3, and stepper motor 3 is provided with the control system of rotary cutterhead, and stepper motor 3 is connected with rotary cutterhead 7 transmissions. The rotary cutterhead 7 is arranged horizontally, and the stepper motor 3 is vertically arranged. The output shaft of the stepper motor 3 is connected with the central hole of the rotary cutterhead 7 by interference fit, and the sensor support seat 14, the shaft end retaining ring 17, the stepper motor The motor main shaft 19 forms a fixed connection with the rotary cutter head 7 through the connecting bolt 15 and the shaft end retaining ring connecting bolt 16 . The stepping motor main shaft 19 and the center hole of the supporting disc 6 are gap fit; the stepping motor 3 is connected with the supporting disc 6 with connecting bolts 10, and the supporting disc 6 is fixed with the supporting base 5 through the connecting bolts 10, and the supporting base 5 It is fixed with the main bracket 18 by connecting bolts 4 .

The driving part 1 can move vertically and horizontally to adjust the position. Lifting frame 2 can be adjusted by the control part according to the height of pruning tree branch. The generator 11 provides power to the stepper motor 3 . When the pruned branch touched the contact sensor 8, the stepper motor 3 drove the rotary cutter head 7 to rotate automatically, and the branch was twisted off while the branch was cut with the blade of the cutter bar 9.

The lifting, driving and trimming of the whole machine can be controlled by computer programming. People can use the remote control to complete all the actions of the machine through the control box.
