Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agricultural mulcher, and more specifically, it lays out strip-shaped membranes sequentially in the longitudinal direction of the shaping ridge surface, and also lays the membranes on both sides in the longitudinal direction of the laid membranes. Concerning work equipment that mounds soil on top.

Multi-farming is becoming widespread as a method of growing crops such as tobacco and lettuce.
It has been implemented.

This mulch farming method covers the entire length of the shaped ridge with a band-like beak such as a plastic film or sheet in order to improve crop survival, protect the crop from frost, wind and rain, and promote crop growth. At the same time as laying the membrane, soil is placed on both sides of the membrane in the longitudinal direction to prevent the membrane from turning over.

As a machine that efficiently implements this multi-farming method mechanically, a ridge shaping device is installed behind a tillage device that is connected to a moving work vehicle such as a tractor so that it can be raised and lowered. A roll support device that horizontally supports the coated willow in a horizontal manner across the direction of travel, and a roll support device that horizontally supports the coated willow and pulls out the membrane from the roll while stepping on both sides of the coated membrane in the longitudinal direction. At least one pair of membrane treads to be laid on top of the tread are provided with a round mulcher that includes at least a ring and at least a pair of soil covering members that cover soil on both sides in the longitudinal direction of the laying body.

By the way, in the conventional mulcher, as is clear from US Pat. In other words, it is normally fixedly connected to the fixed machine frame.

In cases where the mulcher is fixedly connected to the frame of the fixed machine like this, the work is difficult when working on sloped areas such as mountainous areas.

In other words, in order to operate a mobile work vehicle along the contour line KfEj in a mountainous area, the mobile work vehicle must be driven by turning the steering wheel in the direction of the mountain in order to prevent the mobile work vehicle from sliding downhill. In this way, if the traveling work table is cut in the direction of the mountain, the tillage device and ridge shaping device connected to it will also change the posture of the mulcher to the so-called mountain side, and as a result, the ridge shaping work will be carried out in accordance with the uniform pitch. This is also the case with meandering ridges.

In particular, as mentioned above, when the ridge shaping device changes its posture to the mountain side and shapes the ridges on the contour lines as it travels, the tilled soil and ridge shaping are performed at the front, rear, left, right, and center of the ridge shaping device. The ridge is compressed on the crest side of the ridge, and a gap is formed between the ridge and the shaper on the so-called lower side, making it difficult to lay the ridge uniformly with a mulcher, and the extension becomes difficult. In some cases, the membrane was damaged during installation.

The present invention has been devised in view of the above-mentioned circumstances, and is designed to move the front part of the mulcher frame around the vertical axis above the center in the width direction and above the center in the front-rear direction of the ridge shaper provided immediately after the tilling device. The purpose of the present invention is to provide a mulcher that can uniformly cover and lay a membrane over the entire longitudinal direction of the ridge even on sloped land or meandering ridges by pivotably connecting the mulcher and prevents the laid membrane from turning over. .

A second object of the present invention is to provide a pitch fitting at the center or both left and right ends of the support extending rearward from the tilling device. By attaching the pitched metal fittings to the left and right plotting parts and detachably connecting the pitched metal fittings and the pitched metal fittings, the tilling device and the ridge shaping machine can be easily and quickly installed and removed, while also allowing the ridge shaping machine to To provide a mulcher in which a mulcher frame is pivotally connected to the upper center in the width direction and near the center in the front-rear direction so as to be pivotable about a vertical axis.

Third object of the present invention: A mulcher, a ridge shaper, and a mulcher, which are pivotally connected to each other in a freely textured manner around a vertical axis above the center in the width direction and near the center in the front-rear direction, are both slidably fixed in the direction of work progress. The purpose is to provide a mulcha that can be freely set up.
