A kind of chain-and-harrow type farmland residual film pick-up machine
Affiliated technical field
The invention belongs to a kind of farm working machinery, particularly relate to the machinery of picking up the residual film in the face of land, farmland.
Background technology
At present, farmland incomplete film is seriously polluted, most employing manual removals and recovery, and inefficiency, labour intensity is big, often has little time sometimes to reclaim.For solving the farmland incomplete film pollution problem, developed multiple machine for recovering broken film tool both at home and abroad, there are flexible gin pole drum-type machine for recovering broken film, shovel to play a batch machine for recovering broken film, chain type machine for recovering broken film etc. by film retrieving collector operation principle branch.Main type has 1MC-70 type plastic film residue and stubble collecting machine, 1SM-5 solid matter elastic claw type machine for recovering broken film, 1QZ-3900 to put in order ground combine, CSM-130B type toothed-chain type suspension film gatherer, MSM-3 type machine for recovering broken film in seedling stage etc. in the field.Most types are not applied aborning, and the subject matter of existence is: complex structure, fault is many, maintenance is difficult, use cost is high.1SM-5 solid matter elastic claw type machine for recovering broken film is used more aborning, be mainly used in the whole ground of soil after, reclaim the residual film in the face of land before the sowing, the problem of existence is that to receive the film rate low.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of relatively simple for structure, use reliable, maintenance is convenient, receive the high machine for recovering broken film tool of film rate.
To achieve these goals, the invention provides a kind of chain-and-harrow type farmland residual film pick-up machine, form by frame, driving wheel, follower, residual film case, land wheel.It is characterized in that: choosing the film chain belt is a broken line, first half and You Yi Pour angle, ground and front end kiss the earth, latter half be positioned at the top and parallel to the ground of residual film case or with De Pour angle, ground less than in 15 °; Last directive wheel and following directive wheel are positioned at the intersection of choosing film chain belt first half and latter half; Chain belt frame is anterior hinged with driving shaft, and chain belt frame rear portion and driven axle are hinged; Base plate is fixed on the chain belt frame, be positioned at choose the film chain belt below; Break shovel is fixed on the chain belt frame, and the back that is positioned at driving wheel on the lower side.
Above-mentioned chain-and-harrow type farmland residual film pick-up machine is characterized in that: the described film chain belt of choosing is by chain belt, crossbeam with choose the film tooth and form; Crossbeam is connected with chain belt, chooses the film tooth and is fixed on the crossbeam; Chain belt can be detachable chain, bush(ing) chain, bushroller chain, glue belt and profile of tooth rubber strip.
The invention has the beneficial effects as follows: adopt the farmland residual film pick-up machine of said structure design relatively simple for structure, maintenance is convenient, and use is reliable, productivity ratio height, low in energy consumption, residual film rate of recovery height.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation that the present invention chooses film chain belt (4).
Indicating 1 among the figure is frame, and 2 is driving wheel, and 3 is driving shaft, and 4 for choosing the film chain belt, and 5 is last directive wheel, and 6 are following directive wheel, 7 is follower, and 8 is driven axle, and 9 is residual film case, and 10 is land wheel, and 11 is base plate, 12 is chain belt frame, and 13 is break shovel, and 14 is chain belt, and 15 is crossbeam, and 16 for choosing the film tooth.
Embodiment
Embodiment 1:
In Fig. 1: complete machine by frame (1), driving wheel (2), driving shaft (3), choose film chain belt (4), go up directive wheel (5), directive wheel (6), follower (7), driven axle (8), residual film case (9), land wheel (10), base plate (11), chain belt frame (12), break shovel (13) are formed down; In Fig. 2: choose the film chain belt by chain belt (14), crossbeam (15) with choose film tooth (16) and form; It is characterized in that: choosing film chain belt (4) is a broken line, first half and You Yi Pour angle, ground and front end kiss the earth, latter half be positioned at the top and parallel to the ground of residual film case (9) or with De Pour angle, ground less than 15 °; Last directive wheel (5) and following directive wheel (6) are positioned at first half and the latter half intersection of choosing film chain belt (4); Chain belt frame (12) is anterior hinged with driving shaft (3), and chain belt frame (12) rear portion and driven axle (8) are hinged; Base plate (11) be fixed on choose film chain belt frame (12) go up, be positioned at choose film chain belt (4) below; Break shovel (13) is fixed on the chain belt frame (12), and the back that is positioned at driving wheel (2) on the lower side.Chain belt (14) can be detachable chain, bush(ing) chain, bushroller chain, glue belt and profile of tooth rubber strip.
Above-mentioned chain-and-harrow type farmland residual film pick-up machine can drive separate operaton by tractor, also can form combine with straw crushing and field-returning machine etc., and its course of work is: tractor-drawn facility of the present invention advance, the loose film bed soil layer of tine (13) pick; Choose on the film chain belt (4) choose that film tooth (16) buries and along the ground continuous rolling.Choose film tooth (16) when ground surface, the residual film on ground is provoked and carry to residual film case (9), base plate (11) is held anti-its of residual film and is come off; Drive residual film and arrive when choosing film chain belt horizontal segment when choosing film tooth (16), choose being directed downwards of film tooth (16), residual film falls under gravity in the residual film case (9).
Embodiment 2:
The difference of present embodiment and embodiment 1 is the demoulding device is arranged on the lower side choosing film chain belt (4) rear end.
