A kind of towed graduated dial hay rake
Technical field
The utility model belongs to the agricultural machinery application; Be specifically related to a kind of towed graduated dial hay rake that can be in the field the diffusing grass after cradling be tedded, hugs integrated, turn over careless support body (10), base-column (11), left side graduated dial (12), right side graduated dial (13), hydraulic cylinder (14) by supporting leg (1), abase frame (2), crossbeam (3), left lateral travelling wheel and walking wheel carrier (4), right lateral travelling wheel and walking wheel carrier (5), graduated dial support (6), left-handed pivoted frame (7), dextrorotation pivoted frame (8), L type support body (9), centre and form.
Background technology
In existing technology, the main facility of the diffusing grass after cradling being hugged careless operation are to need power drive to hug careless graduated dial, and careless hugging collects or ted thereby completion is loose.Existing facility need tractor that output of back power and hydraulic pressure output are arranged, and are small-sized in the market towed unpowered and have the pullrake of hugging the grass and tedding function less.
Summary of the invention
The utility model purpose is to provide a kind of and can be in the field the diffusing grass after cradling be hugged integrated, the towed graduated dial hay rake that teds.
The purpose of the utility model is to realize through following technical scheme:
A kind of towed graduated dial hay rake mainly turns over careless support body, base-column, left side graduated dial, right side graduated dial, hydraulic cylinder by supporting leg, abase frame, crossbeam, left lateral travelling wheel and walking wheel carrier, right lateral travelling wheel and walking wheel carrier, graduated dial support, left-handed pivoted frame, dextrorotation pivoted frame, L type support body, centre and forms.Abase frame is connected the dead ahead of crossbeam, and supporting leg is supported on the place ahead of abase frame, and left lateral travelling wheel and walking wheel carrier and right lateral travelling wheel and walking wheel carrier are connected to the both sides, rear of crossbeam.Base-column be contained in crossbeam directly over; Left side graduated dial and right side graduated dial are connected on the L type support body through the graduated dial support respectively; The L type support body of both sides is connected on left-handed pivoted frame and the dextrorotation pivoted frame, and left-handed pivoted frame and dextrorotation pivoted frame are installed in the bilateral symmetry of crossbeam and arrange.The base of hydraulic cylinder and the end that is seated in abase frame, the cylinder bar of hydraulic cylinder is connected with base-column through bearing pin.The unpowered driving of this type has 9 graduated dials, and graduated dial is connected on the L type support body through the graduated dial support.The chief component elastic claw of graduated dial is to be processed by spring steel, configuration radially on the graduated dial wheel hub, and the outer end is to rear curved.
The utility model and tractor use.During operation, the abase frame front end of tractor-draw-plate and the utility model articulates.In the process of advancing of tractor, the elastic claw end contacts with ground, drives graduated dial grass is dialled in the job area of next graduated dial, dials successively to last graduated dial, and in the end the narrow end of two graduated dials forms swath.Can left and right swivel mount be folded and launch through driving the flexible of hydraulic cylinder, make complete machine be in transportation or duty.When tedding swath, the graduated dial that the centre is turned on the careless support body puts down.
The utility model can be adjusted to obtain best effect according to different job requirements.Can adjust and hug collection width, ground pressure and hug the collection angle.And this type can also fold, and is convenient to transportation.

Referring to Fig. 1, Fig. 2,1, supporting leg, 2, abase frame, 3, crossbeam; 4, left lateral travelling wheel and walking wheel carrier, 5, right lateral travelling wheel and walking wheel carrier, 6, the graduated dial support, 7, left-handed pivoted frame; 8, dextrorotation pivoted frame, 9, L type support body, 10, the centre turns over careless support body, 11, base-column; 12, left side graduated dial, 13, the right side graduated dial, 14, hydraulic cylinder.
Embodiment
According to accompanying drawing the utility model is done further to describe:
A kind of towed graduated dial hay rake turns over careless support body (10), base-column (11), left side graduated dial (12), right side graduated dial (13), hydraulic cylinder (14) by supporting leg (1), abase frame (2), crossbeam (3), left lateral travelling wheel and walking wheel carrier (4), right lateral travelling wheel and walking wheel carrier (5), graduated dial support (6), left-handed pivoted frame (7), dextrorotation pivoted frame (8), L type support body (9), centre and forms.It is characterized in that abase frame (2) is connected the dead ahead of crossbeam (3), supporting leg (1) is supported on the place ahead of abase frame (2), and left lateral travelling wheel and walking wheel carrier (4) and right lateral travelling wheel and walking wheel carrier (5) are connected to the both sides, rear of crossbeam (3).Base-column (11) be contained in crossbeam (3) directly over; Left side graduated dial (12) and right side graduated dial (13) are connected on the L type support body (9) through graduated dial support (6) respectively; The L type support body (9) of both sides is connected on left-handed pivoted frame (7) and the dextrorotation pivoted frame (8), and left-handed pivoted frame (7) and dextrorotation pivoted frame (8) are installed in the bilateral symmetry of crossbeam (3) and arrange.The base of hydraulic cylinder (14) be seated on the abase frame (2), the cylinder bar of hydraulic cylinder (14) is connected with base-column (11) through bearing pin.The unpowered driving of this type has 9 graduated dials, and graduated dial is connected on the L type support body through the graduated dial support.The chief component elastic claw of graduated dial is to be processed by spring steel, configuration radially on the graduated dial wheel hub, and the outer end is to rear curved.
The utility model and tractor use.During operation, the abase frame front end of tractor-draw-plate and the utility model articulates.In the process of advancing of tractor, the elastic claw end contacts with ground, drives graduated dial grass is dialled in the job area of next graduated dial, dials successively to last graduated dial, and in the end the narrow end of two graduated dials forms swath.Can left and right swivel mount be folded and launch through driving the flexible of hydraulic cylinder, make complete machine be in transportation or duty.When tedding swath, the graduated dial that the centre is turned on the careless support body puts down.
