The residual film of semimounted reclaims and the straw chopping and returning combine
Affiliated technical field
The utility model belongs to a kind of farm working machinery, particularly relates to the machinery that reclaims residual film in the face of land and straw chopping and returning integration of operation.
Background technology
The agricultural crop straw chopping and returning helps improving the organic matter and the nutrient content of soil, improves soil physical property, improves the biologically active of soil, and tangible effect of increasing production is arranged.The agricultural crop straw chopping and returning is an operation that labour intensity is big, expenditure of time is many, seasonality is very strong.If crops straw can not in time be handled, will influence the autumn ploughing operation in farmland, restrict the spring sowing production in the coming year.Adopt stalk crasher with the crops straw chopping and returning at present, plough turns over and places into the soil then.
Behind crop harvesting, the residual film in the face of land needs in time to remove, and is beneficial to the growth of crop in the coming year.The following sweep-out method of main at present employing:
1) manual removal and recovery, inefficiency often has little time to reclaim sometimes.
2) elastic claw is hugged the film machine, uses the hay rake principle the residual film in the face of land is hugged integrated heap or strip, and entrucking transports extraterrestrial then.This method is removed the stalk of chopping and returning easily simultaneously, has lost the effect of straw-returning, and residual membrane removal rate and productivity ratio are lower.
In the prior art, clear film and straw chopping and returning operation are carried out respectively, and operation often, power consumption is big.In order to realize that straw chopping and returning and residual film reclaim one-stop operation and finish, reduce cargo handling operation, reduce production costs, the utility model provides the residual film of a kind of semimounted to reclaim and the straw chopping and returning combine, realizes a tractor serves several purposes.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of multipurpose work tool that can remove the residual film in the face of land behind the crop harvesting, can also finish the crops straw chopping and returning is provided.
In order to realize the foregoing invention purpose, the utility model provides the residual film of a kind of semimounted to reclaim and straw chopping and returning integration of operation facility, send pipe, transmission mechanism, roller for collecting plastic residue, tine, residual film conveyer, film-collecting box and the dark travelling wheel of limit to form by rack-mounted half hanger bracket, gear-box, straw millstone, stalk throwing, it is characterized in that: described straw millstone is positioned at the front portion of facility; Described stalk is thrown and is sent pipe to be connected with described straw millstone; Described roller for collecting plastic residue is positioned at the facility middle part on the lower side; Described tine is positioned at described roller for collecting plastic residue below and links to each other with frame; Described residual film conveyer by residual film take off send impeller and kuppe to form, be installed in described roller for collecting plastic residue the top partially after; Described kuppe takes off described residual film and send impeller to cover.
Above-mentioned facility is characterized in that: described roller for collecting plastic residue is that off-centre is taken off rod-type, is made up of gin pole and cylinder, and rotating speed is 80~110 rev/mins; The eccentric throw of gin pole and cylinder is 6~12cm.
Above-mentioned facility is characterized in that: described residual film takes off and send impeller to be made up of blade and sharf, and it is 30~40cm that described residual film takes off the external diameter that send impeller, 3~6 in blade.
Above-mentioned facility is characterized in that: the cross-sectional profile of described impeller cover becomes involute to launch for take off the direction of rotation of sending impeller along described residual film.
Above-mentioned facility is characterized in that: described tine is made up of a tier pole tooth, bar space width 8~12cm, described bar tooth tilt to install, with 20 °~35 ° of horizontal plane angles.
The beneficial effects of the utility model are: adopt the residual film of semimounted of said structure design to reclaim and crops straw chopping and returning combine, one-stop operation can finish straw chopping and returning and residual film reclaims two operations, high efficiency, low in energy consumption, the membrane cleaning rate height, easy to use and reliable.The high yield that not only can keep plastic mulching to obtain, and help environmental protection and the organic matter and the nutrient that improve soil.

Embodiment
In Fig. 1, Fig. 2, complete machine mainly send pipe (5), transmission mechanism (6), roller for collecting plastic residue (7), tine (8), residual film to take off by half hanger bracket (1), frame (2), gear-box (3), straw millstone (4), stalk throwing and send impeller (9), kuppe (10), film-collecting box (11) and limit dark travelling wheel (12) to form.It is characterized in that: described straw millstone (4) is positioned at the front portion of facility; Described stalk stalk is thrown and is sent pipe (5) to be connected with described straw millstone (4); Described roller for collecting plastic residue (7) is positioned at the facility middle part on the lower side; Described tine (8) is positioned at described roller for collecting plastic residue (7) below and links to each other with frame; Described residual film take off send impeller (9) to be positioned at described roller for collecting plastic residue (7) the top partially after; Described kuppe (10) takes off described residual film and send impeller (9) to cover; Described film-collecting box (11) is a rectangle, is positioned at the rear portion of facility.
During the facility operation, the lower suspension arm (not shown) of tractor is connected with half hanger bracket (1); Power takes off to straw millstone (4), roller for collecting plastic residue (7) and residual film transmission of power by tractor motive power output shaft by gear-box (3) and transmission mechanism (6) and send impeller (9).Straw millstone (4) cuts, pulverizes crops straw after throws and send pipe (5) to shed the facility back, and tine (8) 5~8cm that buries is loose with topsoil.Roller for collecting plastic residue (7) is provoked the residual film in the upper soll layer 5cm scope, along with the rotation of roller for collecting plastic residue (7), takes residual film to the demoulding position, is taken off by residual film and send impeller (9) to take off and throw from roller for collecting plastic residue (7) to deliver to the film-collecting box (11).Film-collecting box (11) is a rectangle, is made up of casing and bottom.Casing is welded into framework by angle steel, and five faces are all formed with Web materials.Base plate and casing are hinged, by the opening and closing of two hook control base plates.
The working depth of facility is by half hanger bracket (1) and the dark travelling wheel of limit (12) control.Facility are when road transport and field transfer, and one-way cylinder plunger (not shown) stretches out and promotes the dark travelling wheel of limit (12) to lower swing, and half hanger bracket (1) is promoted by the tractor lower suspension arm simultaneously, makes the facility rise.When in farm work, the oil cylinder plunger is withdrawn under the effect of facility weight, makes facility drop to the operating position.
