Description

A kind of digging tree device
Technical field
This patent belongs to forest machine technology field, and in particular to a kind of digging tree method and digs tree device.
Background technique
Tree grafting growth be unable to do without tree mover device, and existing digging tree method has two classes, and one kind is large-scale tree mover tool, such as liquid It presses shovel to dig tree vehicle, hydraulic-driven chain type digging tree vehicle, half dise knife static(al) of crawler type and digs tree vehicle etc., there are volume Pangs for these devices Greatly, weight is big, price is high, the common drawbacks such as limitation that is at high cost, being frequently subjected to working space are set in inconvenient to use, digging, has The problem of there is also excavations to be not thorough, and manpower is needed to assist, or even will appear the phenomenon that small stone to fly up is hurted sb.'s feelings;Another kind of side Method is to dig tree tool using simple, and the physical strength by people is excavated, such as: saw chain formula tree mover, vibration spade type tree mover, not only labor Fatigue resistance is big, and low efficiency.With the continuous improvement of people's living standards, present labor cost is higher and higher, hair It is bright a kind of completely new, delicate structure, easy to use, energy-saving and environment-friendly tree mover device, it appears particularly important.
Summary of the invention
The purpose of this technology is to provide simple a kind of structure, compact, easy to operate, easy to use, as long as a people It can complete every dig and set operation, high-efficient digging tree device.
In order to reach the purpose, the technical solution of this patent is as follows:
A kind of digging tree device described in this patent, comprising:
Delver bracket 1;
Hobboing cutter driver 3: there is shell 301, fix rotational power plant and swinging axle 302 on shell 301;
Hob assembly 4: including spiral hobbing cutter 5, hobboing cutter axis 6;Wherein,
Hobboing cutter axis 6: at polyline shaped, at least it is connected by two sections of out-of-alignment hobboing cutter shaft parts 61,62 and is formed;The one of hobboing cutter axis 6 End is fixed on shell 301;
Spiral hobbing cutter 5: at polyline shaped, two sections of out-of-alignment spiral hobbing cutter sections 51,52 are included at least;
Every section of spiral hobbing cutter section 51,52 includes round tube 501, the helical blade 502 being fixed on round tube periphery;
The round tube of every section of spiral hobbing cutter section 51,52 is rotatably arranged on a hobboing cutter shaft part 61,62;Adjacent spiral hobbing cutter It is connected between section 51,52 by hollow universal joint 504;
Rotational power plant: it is arranged in shell 301, output shaft is connected with a spiral hobbing cutter section, with every section of spiral hobbing cutter Section 51,52 is rotated around the axis of corresponding hobboing cutter shaft part 61,62;
Swinging power device: it is arranged on delver bracket 1, output shaft is connected with swinging axle 302, to drive hobboing cutter to drive Dynamic device 3 and hob assembly 4 are around 302 axis oscillating of swinging axle;
When hob assembly 4 is around 180 ° of 302 axis oscillating of swinging axle, the spiral hobbing cutter 5 of polyline shaped or the track of hobboing cutter axis 6 Substantially the 1/4 of spherical surface.
This technology the utility model has the advantages that this patent when in use, is fixed on delver bracket 1 the trunk side for being dug tree Ground, swinging axle 302 extend substantially along the radial direction of trunk;6 place plane of polyline shaped hobboing cutter axis is substantially concordant with ground: Then every section of spiral hobbing cutter section 51,52 is driven to rotate around the axis of corresponding hobboing cutter shaft part 61,62 by rotational power plant, together When drive hobboing cutter driver 3 and hob assembly 4 around 180 ° of 302 axis oscillating of swinging axle by swinging power device;Rotational power Device drives every section of spiral hobbing cutter section 51,52 to rotate around the axis of corresponding hobboing cutter shaft part 61,62, and helical blade 502 is by tree root The soil on periphery is transported to ground, while helical blade 502 can also play the cutting action to tree root.When hob assembly is around pendulum Moving axis rotates 180 °, and tree root lower part soil is simultaneously transported to ground by the i.e. cut-off tree root of the spiral hobbing cutter 5 of rotation, completes tree root soil The excavation of ball half.The other side that digging tree device is moved to trunk can be excavated remaining after the same method again later Half soil ball.This completes the excavations of entire trees.
As to above-mentioned digging tree device further improvement, it is provided in helical blade outer rim multiple for cutting off tree root Cutting tip 12.Helical blade 502 is limited to the cutting action of tree root, can be improved tree root cutting effect using cutting tip 12 Rate.
As to above-mentioned digging tree device further improvement, swinging axle 302 is rotatably supported on delver bracket 1.It excavates Device bracket can play preferable supporting role to shell 301 etc. by swinging axle 302.
As to above-mentioned digging tree device further improvement, swinging power device is hand crank and retarder 2, retarder 2 Input shaft be connected with hand crank.Retarder 2 is worm type of reduction gearing.The worm and gear of high reduction ratio is driven to subtract using manpower Fast device 2, can save heavier motor, engine etc., the present apparatus is lighter and handier.
As to above-mentioned digging tree device further improvement, rotational power plant includes the hobboing cutter driving being fixed on shell Motor 7, is fixed on a spiral hobbing cutter section end and and driving tooth at the driving gear 10 being connected with 7 output shaft of hobboing cutter driving motor The driven gear 11 of 10 engagement of wheel.It drives spiral hobbing cutter 5 to rotate using hobboing cutter driving motor, gear drive, is guaranteeing function In the case where rate, overall mechanism is simplified, this sample digs tree device and is also referred to as electronic digging tree device.
