Technical field
The utility model belongs to agricultural machinery technological field, specifically as required can laterally, the one adjustable press mold covering device in length and breadth of longitudinal adjustment Casing ways.
Background technology
In recent years, along with the change of climatic environment, most of crops are planted after needing plastic film mulch on film, and plastic film mulch becomes operation before a necessary sowing.Existing plastic film mulch device major part is all longitudinal laying plastic along Crop Species planting-line face, and carries out earthing press mold on the both sides of mulch film.The plantation area wider for furrow face, dust storm is larger, the mulch film laid is very easy to be swept by strong wind, tear, and causes no small economic loss; In order to avoid the mulch film completed is destroyed, need artificial on mulch film surface horizontal earthing again, waste time and energy.
Utility model content
The purpose of this utility model is to provide one adjustable press mold covering device in length and breadth, to solve, dust storm is large, furrow face width time, the mulch film laid is easily bad by windage loss, the problem that artificial secondary soil-covering is wasted time and energy.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
One is adjustable press mold covering device in length and breadth, it comprises frame, be arranged on the furrow plough at frame front beam two ends, the pressing wheel be arranged on frame longeron, described frame is provided with rolling stand, described rolling stand is arranged on the rear of described pressing wheel, described rolling stand is connected with the two ends of drum spindle, described main shaft is provided with successively second tin roller, the first cylinder, the barrel of described second tin roller, the first cylinder is equipped with soil outlet, described main shaft is provided with soil conveying mechanism, outside the horn mouth of described second tin roller, is provided with earthing ploughshare.
As further improvement of the utility model, the internal diameter of described first cylinder is less than the internal diameter of second tin roller.
Further improve as of the present utility model, described soil conveying mechanism is helical impeller.
Further improve as of the present utility model, the front beam of described frame is provided with level land plate.
Further improve as of the present utility model, the front beam of described frame is provided with pack roller.
Further improve as of the present utility model, described earthing ploughshare is outer splayed curve form.
Further improve as of the present utility model, described soil outlet is the rectangle extended along the axis direction of the first cylinder, second tin roller.
Further improve as of the present utility model, described first cylinder has 1 at least, and described second tin roller has 1 at least.
In the utility model, soil-covered drum is divided into the first cylinder, second tin roller, and on the barrel of the first cylinder, second tin roller, soil outlet is set respectively, earthing ploughshare is in traveling process, part soil is shoveled in ditch that furrow plough outputs, by the mulch film both sides compacting laid, another part soil is by the port shoveled into second tin roller; When second tin roller, the first cylinder are in one line, during laid out in parallel, soil is transported to the first cylinder, second tin roller by soil conveying mechanism, and the first cylinder, second tin roller are in the process of rolling advance, soil falls to the mulch film surface laid from soil outlet, complete the horizontal earthing in mulch film surface; Internal diameter due to the first cylinder is less than the internal diameter of second tin roller, and therefore both can be socketed; When the first cylinder and second tin roller are socketed mutually, and the soil outlet on the first cylinder and second tin roller barrel by cylinder barrel mutually cover shelter from time, soil falls to the mulch film surface laid from the another port of second tin roller, form longitudinal earthing on mulch film surface; When the first drum sleeve is received in second tin roller, and the soil outlet on the first cylinder and second tin roller barrel overlaps, when not being blocked, part soil falls to the mulch film surface laid from the another port of second tin roller, another part soil falls to mulch film surface from soil outlet, forms sphere of movements for the elephants shape earthing on mulch film surface.
The beneficial effects of the utility model are:
(1) by the change of the first cylinder, second tin roller, soil outlet position relationship each other, achieve the transverse direction on mulch film surface or the conversion of longitudinal earthing, Casing ways can be selected flexibly according to the difference of long-term cropping;
(2) the utility model structure is simple, and utilize the soil outlet on soil conveying mechanism, the first cylinder, second tin roller, complete the earthing on mulch film surface while laying plastic, the mulch film laid and furrow face are fitted closely, are not easily swept by wind and tear;
(3) level land plate or pack roller are set on front beam, can be smooth by earth pack in the process that moves ahead by tractor, livestock or artificial dragging at the utility model, be convenient to laying plastic;
(4) the utility model operation process is time saving and energy saving, has saved planting cost.
