Description
Technical field
It the utility model is related to aquaculture field, more particularly to a kind of culture of Chinese mitten crab weed cutting device.
Background technology
With the development of the social economy, people increase day by day to the demand of river crab product, culture of Chinese mitten crab industry fast development,
Kind grass cultivation is the important model of culture of Chinese mitten crab, and pasture and water for the three-dimensional benign distribution of river crab except providing good environment, purified water
Outside matter, or the source of nutrition that river crab is important, but pasture and water undue growth, excessive dissolved oxygen can be consumed, corrupt end is also easily led
Water quality deterioration is caused, therefore, periodic cleaning pasture and water are particularly important, realize that cleaning pasture and water are saves time and effort, at present, domestic and international city
There are some pasture and water to clear up ship, weed cutting ship on, weed cutting device is made up of cutter and cutting knife transmission device, harvester
Mainly by reciprocating and rotary two kinds, in the course of the work, crank connecting link is with the horizontal certain angle for reciprocating-type cutting device
Degree drives cutter cuts pasture and water by shift fork, makes shift fork master arm and slave arm not in the same plane, shift fork stir it is dynamic
The motion of power group driving lever in the same plane, does not make slave arm planar have rotary motion, produces torque, influences to use the longevity
Life, the friction of shift fork and driving lever in addition is link friction so that the abrasion aggravation of shift fork, reduces the service life of shift fork, directly
It has impact on the service life of harvesting device.
The content of the invention
The utility model is received to solve the above problems, providing a kind of higher receipts grass for culture of Chinese mitten crab area of durability
Cut device.
Technical solution adopted in the utility model：
A kind of culture of Chinese mitten crab weed cutting device, including hull, motor, movable cutter set, driving lever sleeve, rocking bar, small shift fork,
Bent axle and crank connecting link, driving lever is fixed on the surface of movable cutter set, cylinder is provided among driving lever, covers driving lever sleeve on cylinder, shake
One end of bar is prong, and prong is socketed in outside driving lever sleeve, and on one end fixed crankshaft of crank connecting link, the belt wheel on bent axle passes through
Belt and the belt wheel synchronous axial system being located on motor bearings, motor are placed on hull, the other end of crank connecting link and small shift fork
Rotating shaft is connected, and small shift fork is connected between rocking bar by intermediate connecting rod.
Described driving lever sleeve is that periphery is square sleeve.
Described intermediate connecting rod is connected with small shift fork by ball bearing.
The beneficial effects of the utility model：Crank connecting link of the present utility model drives small shift fork, and small shift fork passes through in one
Between connecting rod drive rocker planar do reciprocally swinging, with this smoothly complete driving movable cutter set reciprocating cutting move, Er Qieshe
Driving lever sleeve is counted, rocking bar is contacted with driving lever for face, reduces abrasion, increases the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- hulls；2- motors；3- crank connecting links；The small shift forks of 4-；5- intermediate connecting rods；6- rocking bars；7- prongs；8- is dialled
Rod sleeve；9- driving levers；10- movable cutter sets；11- belt wheels；12- bent axles.
