Description

Spray liquid embedded type roller mulching film paving device

Technical Field

The invention relates to a liquid-spraying embedded type roller mulching film paving device, belongs to the field of agricultural machinery, and mainly has the innovation point of ditching and film mulching modes.

Background

And (3) carrying out ditching, film paving and soil covering and pressing on the traditional plastic film mulching machines such as KDF-1 type, 2BFM-2 type and the like. The traditional mulch applicator needs a great ditching depth and a great film pressing area to ensure the stability of the mulch, so that the mulch utilization rate is not high and the energy consumption is high. The tractor does not go directly, and factors such as earthing device interval is unreasonable lead to the earthing volume improper, the skew turn-up of plastic film. And because the structural dimension restriction, the suppression wheel is less, and the suppression effect is not enough.

Disclosure of Invention

The invention aims to overcome the defects of poor mulching film fixing effect, overlarge mulching film covering area, insufficient sunlight utilization rate and the like of the conventional mulching film machine and provides a novel mulching film covering device.

In order to solve the problems that the effect of mulching film fixation is not good, the mulching film soil covering area is too large, the sunlight utilization rate is not enough, and the like, the adopted technical scheme is as follows: the traditional ditching and film covering mode is improved, so that the ditcher and the ditcher stand column are 45 degrees, and the main purpose is to obliquely embed a small amount of mulching films into soil. The film pressing roller at three different angles is arranged in the middle of the furrow opener, and the main purpose is to better contact the mulching film with soil and achieve better fixing effect. Two water tanks of installation on plastic film machine frame, toward the plastic film edge part slowly drip, its main objective is in order to let the better and soil adhesion of plastic film portion of ingrowing, let the better fixing in soil of plastic film.

Further explaining the technical scheme, the vertical column of the furrow opener is arranged on the adjustable rack, the furrow opener and the vertical column of the furrow opener are arranged on the vertical column of the furrow opener in an angle of 45 degrees, and the travelling wheel is arranged at the front end of the adjustable rack and is matched with the travelling device to complete furrowing.

The small-size press mold cylinder of three different angles passes through the pressure spring by the bracing piece and installs in the frame to guarantee that the press mold cylinder is located the furrow opener middle-end, accomplish in coordination with the furrow opener and spread the membrane.

On the rear end frame of plastic film fixed axle, two water tanks of installation, at the tubule of water tank bottom installation band valve to lead the tubule to the position that plastic film fixed axle both ends are slightly inclined to the inside, make water slowly flow to the plastic film both ends just, thereby make the better adhesion of plastic film and soil.

The back end of the chassis of the frame is provided with a truncated cone type press wheel, and the conical surface is in parallel contact with the ridge edge.

The invention has the beneficial effects that: 1) the embedded mulching film laying device is compact in structure, reliable in work and stable in performance, and improves the mulching film laying quality and the working efficiency; 2) the ditching and film embedding way inclined by 45 degrees changes the traditional film paving way and solves the problem of poor mulching film fixing effect; 3) the mode of obliquely embedding the mulching film solves the problems of excessive soil covering and edge curling of the traditional mulching film machine, saves the mulching film, ensures no soil on the film, and fully plays the roles of light absorption, temperature increase and soil moisture preservation of the mulching film; 4) after the mulching film is embedded into soil, the truncated conical press wheel is directly compacted, so that the mulching film is completely fixed; 5) this embedded plastic film device of laying cover adopts intelligent control press mold intensity and ditching degree of depth, realizes reasonable press mold, reduces the damage to the plastic film and increases operation rate.

Detailed description of the preferred embodiments

The invention is described in further detail below with reference to embodiments shown in the drawings.

The invention works by connecting all parts by a frame, firstly, a walking wheel (6) and a speed regulating motor (5) are placed at the front end of the frame, and the speed regulating motor is arranged at a position which is deviated from the front of a main shaft of the walking wheel. The control box (3) and the liquid box (2) are arranged at fixed positions below the frame.

The furrow opener (16) is arranged on the adjustable frame, and the distance between the left furrow opener and the right furrow opener is 400mm-1500 mm. An acute-angle hoe shovel type opener is arranged on a shovel handle at an angle of 0-90 degrees, and the opener curve analysis formula is that y = 0.3468x²-3.2457x + 36.111. The traveling wheels (6) (20-100 r/min) are arranged at the front end of the adjustable frame, and the rotating speed is obtained from the speed regulating motor (5) (the working rotating speed is 125-.
