Abstract

The utility model relates to a ridge drilling mulching film covering machine for ridge drilling devices without a driving shaft, which belongs to scarification equipment for agronomic crops. Agronomic crop planting through covering plastic film (which has the abbreviation of the mulching film) on soil surfaces is a novel cultivation method at present. Procedures, such as ridge drilling, film pavement, earth coverage, etc., which are needed by mulching film coverage can be accomplished by the utility model in one step. The utility model is suitable for covering various mulching films with the covering thickness smaller than 0.015 mm. A ridger of a ridge drilling device is a ridge drilling circular disk which does not need the driving of a driving shaft. A ride type small brougham tractor of 12 horsepower can be used for traction.

Description

Path-raising plastic film-spreading machine without driving shaft

The utility model belongs to a kind of crops scarification equipment.It is a kind of newer cultivation methods that plastic film (abbreviation mulch film) is covered soil surface plantation crops, and covering with plastic film need pass through operations such as ridging, shop film, earthing, and this machine can once be realized these operations, finishes the task of covering with plastic film.

Existing ridging plastic mulching machine is made up of ridging device, shop film device, covering device, land wheel, frame, hanger bracket etc. tractor-drawn.The tie ridger of the ridging device of covering with plastic film is cultivator or spiral tie ridger.Adopt sliding bearing in the disk coverer in view of covering device, the profile of the both sides press mold wheel of the ridge forming board of ridging device and shop film device is undesirable, so covering with plastic film is second-rate.

Known ridging plastic mulching machine (referring to the clear 58-8806 of Japan Patent), use tractor-drawn, by ridging device, shop film device, frame, vertically cross bar, borrow the rotatable jack back of sleeve, height-adjustable vertical rod, towing plate and auxiliary body thereof to form.The shop film device by film roll, put film frame, press mold wheel and support arm constitutes.This machine is in one or several ridge moulding, spreads film in the ditch between ridge and ridge together.

Because the ridge forming board of this machine ridging device is a broken line, behind the ridging, the surface quality on ridge is relatively poor, and is smooth inadequately, smooth to the mulch film surface that makes covering.The press mold of film pressing device wheel is for cylindrical again, and outer loop material is a sponge, only presses the mulch film in the ditch, and not firm, as to require ditch wider width, waste soil are stretched directly, pressed to the mulch film that covers on the ridge.Because of there not being covering device, the mulch film outside of Gu Bianlong needs artificial earthing, and the compacting of the only pressured film wheel of the mulch film of middle furrow is not firm.The method of also spreading film in the ditch between the ridge only is applicable to the occasion of sprinkling irrigation, and is not suitable for the furrow irrigation that China extensively adopts, and mulch film consumption is many again.

The purpose of this utility model is to eliminate above-mentioned shortcoming, promptly improves the quality of covering with plastic film, make the mulch film smooth surface, smooth, the jail of mould, do not need artificial earthing.

The overall process of the utility model covering with plastic film is ridging, shop film and earthing, is finished by ridging device, shop film device, covering device respectively.The ridging device is shown by ridging disk 2(Fig. 1,2) and ridge forming board 3 etc. form.The shop film device by film roll 5, put film frame 6, ridge face press mold wheel 7, both sides press mold wheel 9 etc. and form.Covering device is made up of disk coverer 10 and support thereof etc.Other has auxiliary body's land wheel 4, frame 8, hanger bracket 1 etc.

The tie ridger of ridging device is that ridging disk 2(Fig. 1,2,7 shows), its structure is the anodontia arc disk of thin-walled, adopts the rolling bearing with two-way thrust function, directly is contained on the fixed axis, does not need drive shaft, directly drives during by frame 8 operations.Also available scraper plate of ridging disk 2 or ploughshare replace.Ridge forming board 3(Fig. 3,4,5, show) vertical section be arc, frictional resistance is little, the ridge shape rule that shaping goes out, smooth, the face of land is smooth.

The press mold wheel (Fig. 1,2,6 shows) of shop film device is divided into two kinds, a kind of is ridge face press mold wheel 7, one on every ridge compresses the middle part mulch film on ridge, and another kind is that two both sides press mold wheel 9 arrives cylindrical for conical transition about every ridge, make with flexible materials such as foamed plastics or foam rubber or rubber, the operating position of both sides press molds wheel 9 is at bottom of trench, and in the both sides on ridge, and that mulch film 18 is stretched on the ridge like this is straight, the jail of pressure, the width of ditch is narrow, saves the soil.Do not spread film in the ditch, save mulch film.Both be fit to sprinkling irrigation and also be fit to furrow irrigation.

The disk coverer 10 of covering device is at mulch film both sides earthing, and soil tightly is pressed in mulch film on the face of ridge, manually earthing.

Ridging disk 2 of the present utility model and disk coverer 10 and their parts such as bearing portions can general (Fig. 7 show).

The utility model is covering with plastic film one ridge or two ridges (Fig. 1,2 has been the embodiment on a ridge) simultaneously, and during work, tractor is connected with hanger bracket 1, drives the complete machine operation by frame 8.The quantity of ridging disk 2 is fixed by ridging quantity, two on every ridge.Per two ridging disks 2 become a cone angle with direct of travel, angle can be regulated, and soil is concentrated to the middle part on ridge, and the soil after concentrating can be put ridge shape in order by agriculture requirement through the ridge forming board, and the vertical section of ridge forming board 3 is arc (Fig. 4 shows).Film roll 5 is installed on the film roll frame 6, the mulch film of having spread is compressed by a ridge, the every ridge face press mold wheel 7 middle part mulch films with the ridge, and two both sides press mold wheel 9 both sides mulch films with the ridge compress about every ridge, for preventing that wind from blowing afloat mulch film, at last by disk coverer 10 earthing, disk coverer quantity is identical with ridging disk quantity, and per two become a cone angle, adjustable angle with direct of travel.Two land wheels 4 play guiding and profiling effect, can adapt to the rugged variation in ground, guarantee operation quality.Be applicable to ridging, shop film, the earthing a whole set of covering with plastic film operation of cladding thickness at the multiple mulch film below 0.015 millimeter.
