Description

Ridge side plastic film ridging shovel

Technical Field

The application belongs to the technical field of agricultural machinery, in particular to a ridge side mulching film forming shovel.

Background

The main components of the mulching film used in China are hydrocarbon compounds such as polyethylene and the like, the mulching film can exist in soil for a long time and is not easy to decompose, and the residual mulching film brings great influence on the structure of the soil and the growth of crops, so that the mulching film is called as 'white pollution' of farmlands.

The film-acting shovel is used for simultaneously shoveling and cutting off the crop stubbles of the mixture of the residual mulching films and the soil, so that the film-acting shovel has a certain penetration depth. At present, a film lifting shovel on a residual film recycling machine is designed aiming at a corn flat-planting area, a shovel blade is used for directly digging into the lower part of a mulching film to shovel the mulching film, the corn planting mode in the northeast area is mainly ridge planting, namely, the corn is planted on a trapezoidal ridge stand, the two sides of the mulching film are pressed under the soil on the two sides of the ridge stand, the existing film lifting shovel cannot loosen the soil on the two sides of the ridge stand to lift out the mulching film, so that the recovery rate of the mulching film is reduced, and the root growth and development of crops in the next year are influenced in the residual soil of the mulching film.

Therefore, it is an urgent technical problem to be solved by those skilled in the art to provide a new mulch lifting shovel for mulching films on both sides of a ridge.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem, the utility model provides a ridge side plastic film skinning shovel, including shovel handle, shovel point, shovel face, shovel wing, the shovel point passes through the bolt fastening at shovel face front end, the shovel face includes the skinning curved surface and promotes the curved surface, skinning curved surface and promotion curved surface an organic whole are formed into the shovel face that has the skinning curved surface and promote the curved surface, one side of shovel face is provided with the shovel wing, shovel wing and shovel face fixed connection.

The further scheme is that the film-forming curved surface is a sine curved surface, the curved surface equation is that y is 50cos alpha, the soil and the mulching film vibrate after passing through the film-forming curved surface, and the mulching film is much lower than the soil density, so that the initial separation of the mulching film and the soil is realized.

Further, the soil-entering angle alpha of the shovel tip is 20 degrees.

The further proposal is that the lifting curved surface is a second-order continuous curved surface, and the curved surface equation is x²+y²＝H²。

The further scheme is that the height H of the lifting curved surface is 150 mm.

The further scheme is that a cylindrical protrusion is arranged in the middle of the lifting curved surface, and soil and a mulching film can slide to two sides through the cylindrical protrusion to be separated when the film removing shovel works, so that blockage is avoided.

The further scheme is that the shovel wings fixedly connected with one side of the shovel surface are turning curved surfaces, and the turning angle beta of the turning curved surfaces is 30 degrees.

The further proposal is that the shovel wings are provided with soil leaking holes with the length of 150mm and the width of 30mm, which aims to filter the soil carried by the mulching film when the shovel wings overturn to ridge platforms, and prevent the soil from being blocked due to overlarge soil amount.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses to northeast ridge culture area, can play the plastic film of pressing in the ridge both sides and vibration isolation, the plastic film passes through the shovel wing curved surface of side and overturns to the ridge on the recovery unit of being convenient for retrieve, is provided with soil leakage hole on the shovel wing and prevents that the upset soil volume from producing excessively greatly and stopping up, has apparent effect to shoveling ridge both sides plastic film.
