Abstract
A kind of swash drive for blue or green tea picking mechanical that the utility model provides, comprises cam spring mechanism and tooth bar, gear mechanism.Push rod is promoted when cam together rotates with motor output shaft, under the cooperation of spring, make push rod do linear reciprocating motion, tooth bar on push rod coordinates with the gear be fixed on fork, the linear reciprocating motion of push rod is converted to the left-right rotation of fork, and then realizes swinging of cutter.The transmission mechanism that the purpose of this utility model is to provide a kind of simply efficient rotary motion by motor to become cutter and swings, realizes swinging the blue or green tea of hoisting type and plucks action.
Description
Technical field
The utility model relates to blue or green tea picking mechanical, particularly a kind of swash drive for blue or green tea picking mechanical.
Background technology
Tea picking lasts work that is the longest, that spend man-hour maximum in tea garden management.Concentrating and the area of lack of labor in tea place, often because plucking not in time, and having a strong impact on the Yield and qualities of tealeaves.Meanwhile, because cost of labor goes up fast, the ratio that blue or green tea harvesting cost accounts for whole Tea Production cost is more and more higher.Thus the Bi Hangzhi road that the higher mechanical picking technology of efficiency is Tea Production industry is developed.
Traditional machinery of picking tea-leaves adopts cutting Softening mostly.Because of cutting Softening easily damage blue or green tea, after developed again lifting picked technology.Promoting the principle of plucking is that the clamping of the stem of tealeaves tender shoots also upwards lifts until broken by tea picker.The operating principle that the principle that lifting is plucked and finger pluck tealeaves is close, little to the damage of blue or green tea.
Early stage lifting picker adopts rotary mostly, has both realized promoting by two cutters relatively rotated and has plucked.This mode has individual shortcoming, only have the work plane relatively rotated up can realize blue or green tea exactly and pluck, and the work plane be relatively rotated down adjacent with it can not be used, and reduces picking efficiency.Therefore, after developed the blue or green tea of swing type and promoted picker, both cutter can upwards swing left and right, and except the cutter being arranged on edge except, the left and right work plane of each cutter all can realize promoting and pluck, and improves mechanical picking efficiency of picking tea-leaves.
Utility model content
The utility model provides a kind of swash drive for blue or green tea picking mechanical, by cam spring mechanism, the rotary motion of motor is become straight reciprocating motion, by tooth bar, gear mechanism, linear reciprocating motion is become roll motion again, make the cutter of blue or green tea picking mechanical realize swinging lifting and pluck action.
The technical solution of the utility model is as follows.
A kind of swash drive for blue or green tea picking mechanical that the utility model provides, comprises cam spring mechanism and tooth bar, gear mechanism.Described cam spring mechanism comprises cam, push rod, sliding bearing, spring and support, and cam is connected with the rotary output axis of motor, and support and sliding bearing coordinate support push rod, and spring is axially disposed between push rod and support along push rod; Tooth bar in described tooth bar, gear mechanism is arranged on push rod, and gear is fixed on one end of fork, and the other end of fork is equipped with cutter, and fork, by bearings, can rotate to the left and right; Push rod is promoted when cam together rotates with motor output shaft, under the cooperation of spring, make push rod do linear reciprocating motion, tooth bar on push rod coordinates with the gear be fixed on fork, the linear reciprocating motion of push rod is converted to the left-right rotation of fork, and then realizes swinging of cutter.
The rack and pinion cooperatively interacted in described tooth bar, gear mechanism is diagonal-cut rack and angular gear.
Described spring can also be located between cam and sliding bearing.
Described cam is dish type turning cam.
The beneficial effects of the utility model are: the transmission mechanism providing a kind of simply efficient rotary motion by motor to become cutter to swing, and realize swinging the blue or green tea of hoisting type and pluck action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 cam, 2-push rod, 3-spring, 4-support, 5-fork, 6-cutter, 7-sliding bearing.
Embodiment
The technical solution of the utility model is further described, described in should be appreciated that the claimed scope of the utility model is not limited to below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of swash drive for blue or green tea picking mechanical that the utility model provides, comprises cam spring mechanism and tooth bar, gear mechanism.Described cam spring mechanism comprises cam 1, push rod 2, sliding bearing 7, spring 3 and support 4, and cam 1 is connected with the rotary output axis of motor, and support 4 and sliding bearing 7 coordinate support push rod 2, and spring 3 is axially disposed between push rod 2 and support 4 along push rod; Tooth bar in described tooth bar, gear mechanism is arranged on push rod 2, and gear is fixed on one end of fork 5, and the other end of fork 5 is equipped with cutter 6, and fork 5, by bearings, can rotate to the left and right; Push rod 2 is promoted when cam 1 together rotates with motor output shaft, under the cooperation of spring 3, make push rod 2 do linear reciprocating motion, tooth bar on push rod 2 coordinates with the gear be fixed on fork 5, the linear reciprocating motion of push rod 2 is converted to the left-right rotation of fork 5, and then realizes swinging of cutter 6.
Cam 1 is dish type turning cam.One end of push rod 2 is passed sliding bearing 7 and is contacted, accepts the thrust of cam 1 with cam 1, and the other end is connected with support 4 through another sliding bearing, and arranges spring 3 between push rod 2 and support 4.Push rod is equipped with tooth bar except the part that needs coordinate with sliding bearing.Spring 3 also can be located between sliding bearing and cam.
The two ends of fork 5 are separately fixed on two rolling bearings, and the installation direction of fork 5 is just in time vertical with the installation direction of push rod 2.One end of fork 5 is connected with cutter 6, and the other end is provided with the roller gear coordinated with push rod 2 upper rack.Gear on tooth bar on push rod 2 and fork 6 is helical teeth.Helical teeth coordinates more steadily, transmission efficiency is higher.
