Description

A kind of elastic claw sprocket-type machine for recovering broken film
Technical field
The invention belongs to agricultural mechanical field, particularly a kind of elastic claw sprocket-type machine for recovering broken film being applicable to overlay film comparison rule, the less crop of root stubble.
Background technology
In recent years, plastic mulching cultivation technology promotes the use of in the cultivation in vegetable plot, solves the low temperature water shortage problem in cold shut regional nonirrigated farmland, thus starts large scale application.After adopting mulching planting technique, due to the increase of effective temperature, breeding time extends relatively, extensively can adopt middle-late ripening variety, and quality and yield is increased substantially.Meanwhile, make the Shi Zuo district of various crop pass, expand northwards, thus more effectively can utilize land resources.The soil moisture conservation effect that plastic mulching produces, impels crop root deeply to prick, and be thus also a drought-relief measure, this is for effectively utilizing water resource, and there is its own strategic significance in development China early agricultural.
Though mulching planting technique is the effective way improving crop yield, if the residual film being retained in field can not be reclaimed in time, if things go on like this, not only can causes environmental pollution, also will form serious harm to agricultural production itself.Used plastic collection problem is one of key factor affecting agricultural production sustainable development, this point be familiar with by increasing people.The current Chinese government and some agricultural production sectors have started to drop into human and material resources and financial resources to address used plastic collection problem.But as a whole, because China's mulching planting area is wide, plastic film mulch year limit for length, and used plastic collection process not in time, causing rural area residual film quantity of giving up sharply to increase, there is " white pollution " in many places.
The MS-2 type dish film gatherer in seedling stage of existing Northeast Agricultural University development, principle be break shovel by the press mold soil loosening of both sides, ridge, two film rolling tooths roll along ridge to forward position, are rolled by mulch film by film stir-up tooth, film cuts by cutting membrane knife, by the rolling of film rolling tooth by film around on the film rolling tooth of both sides.This machine makes film twist on film cylinder completely on the one hand, must unload film, unload film more loaded down with trivial details, difficult when unloading film with cutter from centre by film cut-out; On the other hand, winder wheel is driving wheel, and the plastic elongation due to residual film is not compensated and causes winder unreliable.
The IMC-70 type damaged film gathering stubble collecting machine of Inner Mongolia Autonomous Region agricultural mechanization Research Institute, during operation, tractor is utilized to advance, the residual film root stubble be embedded in soil scoops up by two perching knives in the lump, be transported in bolter through transmission mechanism, residual film, root stubble and soil block rotate in roller screen, and under centrifugal action, soil block is crashed to pieces and is thrown to ground by sieve screen apertures.Stay the residual film in roller screen, root stubble be thrown in collection film stubble basket, after collection is full, by people operate film stubble unloaded put in heaps.This machine by residual film and root stubble entangled, can not separately only have by burning be separated, cause used plastic collection rate low.In addition, root stubble and residual film all scoop up by two perching knives, and be equivalent to earth's surface sieve to sieve one time, power consumption is larger.

Embodiment
Below in conjunction with accompanying drawing, be further described the specific embodiment of the present invention, the present invention is not limited to following examples.
As depicted in figs. 1 and 2, front view and the vertical view of elastic claw sprocket-type machine for recovering broken film of the present invention is respectively.
The film-collecting box 8 that described elastic claw sprocket-type machine for recovering broken film comprises frame 19 and is arranged in frame 19, hitch frame 1 is connected to frame 19 front end, and land wheel 6 is arranged symmetrically in the left and right sides of frame 19.Land wheel 6 and the first drive sprocket 7 are coaxially installed.First driven sprocket 11 is arranged on film-collecting box 8, second cam 12 and the 3rd cam 14 are symmetrically distributed in the first driven sprocket 11 both sides, are arranged on film-collecting box 8, and described first drive sprocket 7 is connected by Chain conveyer with the first driven sprocket 11, second cam 12 and the 3rd cam 14; Second cam 12 and the 3rd cam 14 and the first drive sprocket 7 rotating in same direction, the first driven sprocket 11 and the first drive sprocket 7 rotate backward.Second drive sprocket 13 is arranged on the bearing block of frame 19, coaxially installs with the first driven sprocket 11.Described second drive sprocket 13 is connected by crawler belt 5 with the second driven sprocket 2, and the second driven sprocket 2 is arranged on the second driven chain wheel shaft 15.Described crawler belt 5 is by the first cam 4 tensioning.Described crawler belt 5 is furnished with many row's crawler belt bars 18, crawler belt bar 18 is furnished with multiple elastic claw 10; In the present embodiment, be furnished with 6 row's crawler belt bars 18 altogether, often arrange on crawler belt bar 18 and be evenly distributed with 9 elastic claws 10.Demoulding plate 9 is fixed on film-collecting box 8, and demoulding plate 9 has multiple gap, and elastic claw 10 passes from the gap of demoulding plate 9.
Described crawler belt 5 surface is all covered with lightweight and does not leak film 16, and as canvas, avoid mulch film to be wrapped on crawler belt 5, elastic claw 10 does not leak film 16 from lightweight and passes.
Described first cam 4 is rigidly connected with tensioning apparatus axle 17, and tensioning apparatus axle 17 is arranged in frame 19 by bearing block, and extension spring 3 side is connected with the ear that draws in frame 19, and opposite side is connected with the ear that draws on tensioning apparatus axle 17.When extension spring 3 shrinks, ear and frame 19 draw ear close to drawing on tensioning apparatus axle 17, tensioning apparatus axle 17 is rotated counterclockwise, because the first cam 4 is rigidly connected with tensioning apparatus axle 17, and then first cam 4 movement counterclockwise, thus the first cam 4 is increased with the vertical range of frame 19 curb girder, crawler belt 5 promotes downwards by the first cam 4 then, entirety increases the stroke of crawler belt 5, makes crawler belt 5 tensioning.
Elastic claw sprocket-type machine for recovering broken film of the present invention is operationally:
Described hitch frame 1 is connected with tractor, tractor provides power, hitch frame 1 drives land wheel 6 rolls forward, land wheel 6 drives the first drive sprocket 7 to rotate, thus drives the first driven sprocket 11 to rotate backward, and the first driven sprocket 11 drives the second drive sprocket 13 to rotate, thus drive the second driven sprocket 2 to rotate, and then driving crawler belt 5 to rotate, the rotation of crawler belt 5 drives elastic claw 10 in the above to rotate, thus drives the shuttling movement of whole machine for recovering broken film; Elastic claw 10 contacts with mulch film when forwarding ground location to, thus mulch film can be provoked, elastic claw 10 turns to the position of demoulding plate 9 with crawler belt 5 with the mulch film of provoking, because elastic claw 10 passes from the gap of demoulding plate 9, the mulch film that elastic claw 10 is provoked is taken off by demoulding plate 9, and the film taken off is collected by film-collecting box 8.When extension spring 3 is strained, drive the axle of the first cam 4 to rotate counterclockwise, therefore whole crawler belt 5 can be strained by the first cam 4, to strengthen the adaptability to landform.
