The utility model discloses an improved structure of a transmission device of a spiral cutting tool slash chopper, which comprises a primary planet transmission device, the device is composed of a transmission gear, a primary planet gear, a primary gear ring and a primary planet carrier, wherein, the transmission gear is in coaxial arrangement with a motor main shaft, the primary planet gear is evenly distributed at one side of the primary planet carrier circumferentially by a gear shaft, the inner side thereof is meshed with the transmission gear, and the outer side thereof is meshed with the primary gear ring, and the other end of the primary planet carrier is connected and provided with a secondary planet transmission device. The utility model overcomes the defects of short transmission chain and small output torque of the current transmission device of the spiral cutting tool slash chopper, the former primary planet transmission device is changed into the secondary planet transmission device through adding the primary planet transmission device, so larger output torque can be obtained under the condition of invariable motor power, thereby meeting the requirements on actual processing and improving the product performance.

Description

A kind of structure-improved of spirality cutter chipper transmission device
Technical field
The utility model relates to a kind of structure-improved of spirality cutter chipper transmission device.
Background technology
In the application of graden machine chipper, general chipper is the machine shakiness when the cutting branch, shake greatlyyer, and its stripping and slicing often has adhesion, shortcomings such as need manual adjustment cutter.And the topping machanism of forming with the spirality cutter, compare with traditional chipper, it is neat that this topping machanism has stripping and slicing, stable cutting, need not to regulate characteristics such as cutter, shortcoming is: it directly carries out transmission by motor by an one-level planetary driving device in use, this one-level planetary driving device includes a travelling gear, a plurality of planetary gears, a ring gear and a planet carrier are formed, wherein travelling gear and the coaxial setting of electric machine main shaft, planetary gear is circularly and evenly distributed by gear shaft and is arranged on an end of planet carrier, planetary gear is inboard to be meshed with travelling gear, its outside is meshed with ring gear, and the other end of planet carrier directly connects the spirality cutter, and cutter is done rotation synchronously with planet carrier during work., because the driving-chain of whole transmission device is shorter, cause under rated power its output torque little here, its maximum cutting branch footpath is 32CM, can't satisfy a requirement of cutting of those major diameter branches.
The utility model content
The purpose of this utility model is to provide a kind of structure-improved of spirality cutter chipper transmission device, it is by increasing the one-level planetary driving device, become the secondary planet transmission device by original one-level planetary driving device, under the constant prerequisite of power of motor, obtain bigger output torque, satisfy the needs of real work, improved properties of product.
For achieving the above object, the utility model is by the following technical solutions:
A kind of structure-improved of spirality cutter chipper transmission device, include an one-level planetary driving device, this device is made up of travelling gear, primary planet pinion, one-level ring gear and primary planet carrier, wherein travelling gear and the coaxial setting of electric machine main shaft, primary planet pinion is circularly and evenly distributed by gear shaft and is arranged on an end of primary planet carrier, its inboard is meshed with travelling gear, its outside is meshed with the one-level ring gear, and it is characterized in that: another the auspicious connection of described primary planet carrier is provided with a secondary planet transmission device.
Above-mentioned secondary planet transmission device comprises sun gear, secondary planet wheel, secondary ring gear and secondary planet frame, wherein sun gear and primary planet carrier are connected, secondary planetary gear is circularly and evenly distributed by gear shaft and is arranged on an end of secondary planet frame, its inboard is meshed with sun gear, and its outside is meshed with the secondary ring gear; The outside end face of described secondary planet frame is provided with the cutter snap-in structure.
Between above-mentioned one-level planetary driving device and the secondary planet transmission device baffle plate is set.
The utility model is at first by the driven by motor travelling gear, and after the deceleration of one-level planetary driving device, drive sun gear, slow down through the secondary planet transmission device again, finally drive the spirality cutter and carry out work, compare with existing transmission mechanism by the secondary planet frame, whole driving-chain length has increased by one times,, increased output torque, can satisfy the needs of actual processing, its maximum broken branch diameter can reach 45cm, has improved the performance of chipper greatly.
In addition, influence operate as normal, between one-level planetary driving device and secondary planet transmission device, a baffle plate is set for avoiding primary planet carrier and the generation of the secondary planetary gear in secondary planet transmission device friction in the one-level planetary driving device.
