The pinch rollers tension the flax pulling belt and half wrap the flax pulling wheels which are provided with a nearside divider 6 at the front end. The conveying apparatus is composed of two conveying belts with wheel hangers and installed at one side of the machine frame, the conveying belts are parallelly appressed with the flax pulling belt, and the hanging and lifting apparatus is installed on the top of the machine frame. The flax puller is hung in front of a tractor and powered by the tractor, and the pulled flax drops to the ground surface and forms continuous strip mats.

Description

The suspension type flax-picking machine

Technical field

The utility model belongs to the agricultural machinery of gathering in the crops flax.

Background technology

Existing flax-picking machine.Suspension type flax-picking machine as the former Soviet Union, or the Belgian flax-picking machine of walking certainly, its sesame removing assembly is installed in the frame top by a very long arch bend pipe, causes weight to increase, complete machine seem heaviness and poor rigidity, the hemp-plucking wheel diameter is big, apart from the ground height, and flax plant height of choosing, narrow range, the technology of can only choosing length flax more than 500mm, bad adaptability is leaked and is pulled out the rate height.The assemblage zone that flat belt that the flax pulling band adopts and V-belt constitute, the cost height, service life is short, haves much room for improvement.

The utility model content

The purpose of this utility model is to provide a kind of light weight, simple in structure, wide adaptability, completed dialing rate height, it is reliable to carry, flax pulling band cost is low, the suspension type flax-picking machine of long service life.

The utility model is made up of frame, decelerator, driving wheel, follower, flax pulling band, hemp-plucking wheel, contact roller, conveying plant and suspension hoisting device; Driving wheel and follower are installed in the two ends of frame respectively, and the flax pulling band hangs on driving wheel and the follower, and speed changer is installed on the frame, and the output shaft of speed changer links to each other with driving wheel; One group of hemp-plucking wheel is installed on the frame by bent frame, hemp-plucking wheel is installed in the outside of flax pulling band, and one group of contact roller misplaces mutually with hemp-plucking wheel and is installed on the frame, and contact roller is installed in the inboard of flax pulling band, contact roller makes the tensioning of flax pulling band and partly wraps hemp-plucking wheel, is provided with nearside divider at the front end of hemp-plucking wheel; Conveying plant is made up of two belt wheels extension conveyer belt, and is installed in frame one side, and conveyer belt and flax pulling band are close to parallel; Suspension hoisting device is installed in above the frame.

Above-mentioned flax pulling band is identical with the linear velocity of conveyer belt.

Hemp-plucking wheel and nearside divider are fixed as one, and have simplified the structure of flax-picking machine greatly, have alleviated weight, have strengthened rigidity.Reduce the distance between the adjacent two nearside divider center lines and the diameter of hemp-plucking wheel, its distance is not more than 280mm, diameter is not more than 210mm, and the hemp-plucking wheel device is lower, the minimum 95mm in its wheel rim below, this just enlarges the scope of flax plant height of choosing, and the above flax of technology length 350mm all can be chosen, and has improved completed dialing rate.The conveyer belt cover of conveying plant part is around on a last hemp-plucking wheel and delivery wheel and walk around contact roller, and several groups of sesame removing assemblies flax of choosing is all transferred out by conveyer belt and the direct clamping of flax pulling band like this, has eliminated and has skidded, reliable operation.Flax pulling band of the present utility model adopts V belt, both transferring power stably, and flax of clamping reliably again, and cost is low, and the life-span is long.

Embodiment

Below in conjunction with accompanying drawing the course of work of the present utility model is given a detailed account:

Frame 9 of the present utility model is articulated on the medium-sized tractor by suspension hoisting device 10, the duplex chain wheel of flax-picking machine decelerator 2 links to each other with tractor dynamic power, power through power take-off by major axis of two pairs of sprocket wheels, two cover universal drive shafts, two want minor axis, a pair of umbrella shape tooth is sent to the driving wheel 1 of flax-picking machine, flax pulling band 8 covers hang on driving wheel 1 and the follower 7, and walk around six contact rollers 5, hemp-plucking wheel 13 is installed on the frame 9 by bent hack lever 12, and forms a bending channel by five section combinations with contact roller 5.Driving wheel 1 is the driving wheel in the whole system, and power is provided by tractor.Nearside divider 6 and grain lifter 11 are divided into five crop bands with flax when flax-picking machine advances, and the surface of five hemp-plucking wheels that turn clockwise 13 of flax guiding sesame removing assembly 4.Cane tightly is clipped in one section circular arc passage between flax pulling band 8 and the hemp-plucking wheel 13, and arc section is limited by two contact rollers 5.

The cane that is in the passage is pulled out under the acting in conjunction of the forward travel of the gyration of hemp-plucking wheel and flax-picking machine, and the cane bundle of extracting (if the direction of advancing along loom is seen) quilt cover left is transported to the conveying plant of being made up of delivery wheel 14, conveyer belt 15, support 16 and hemp-plucking wheel 13 3.Therefore the cane order by a sector transfer of passage to next section, close conveying plant Fig. 3 and cover transfers out around one section flax pulling band, the 8 common clampings on driving wheel 1 and the 6th contact roller 5 from the Far Left section, falling earthward forms continuous bar and spreads.
