Description

  TECHNICAL FIELD The present invention relates to an agricultural sheet laying machine effective for sticky cultivation.

  In open field cultivation in crop cultivation or horticulture, tunnel cultivation and multi-cultivation are known as cultivation methods for improving the influence of planted crops and cultivation floors from the surrounding environment. Tunnel cultivation is a cultivation technique in which a plurality of arch-shaped frame materials straddling a cultivation floor are arranged along the cultivation floor, and a covering material is covered on the frame material to form a cultivation space for the crop on the cultivation floor. On the other hand, multi-cultivation is a cultivation technique that covers the field surface of the cultivation floor with a covering material, and is a technique for improving the influence of the surrounding environment on the soil and obtaining effects such as soil temperature adjustment and prevention of soil drying. The ground part of the crop is exposed to the surrounding environment by making a hole in the covering material.

  In contrast to these methods, a cultivation method called “sticking” is a method in which the cultivation floor is directly covered with a covering material and the above-ground part of the crop is grown under the covering material. This method is a cultivation method that can obtain the advantages of both tunnel cultivation and multi-cultivation, and can save time-consuming operations such as laying frame materials in tunnels and drilling holes in covering materials in mulch.

  As a machine for covering a cultivation floor with a covering material (a sheet material or a film material), a machine mainly for tunnel cultivation or multi-cultivation is known. For example, Patent Document 1 below describes a tunnel-shaped film stretching device that drives an inverted U-shaped frame in the transverse direction of the ridge while driving the frame at a predetermined interval and then covers the film in a tunnel shape on the frame. . In Patent Document 2 below, it is possible to continuously lay a multi-sheet in a state with an appropriate slack without applying tension in the length direction so that a multi-sheet can be laid in the furrow. A possible multi-laying machine is described.

Japanese Patent No. 2626835 JP 2007-189992 A

  Solid-pipe cultivation is a cultivation technique that is expected to promote germination, prevention of missing stocks, growth promotion / yielding effect, prevention of stem and leaf and root bulb damage due to cold, insect protection, frost prevention, wind protection, bird protection, etc. However, because it is a technique that does not provide frame material as in tunnel cultivation, or does not provide a hole that opens the ground part as in multi cultivation, depending on the type of cultivation crop and the shape of the cultivation floor, It may be necessary to form an effective cultivation space.

  It is preferable that a cultivation space that is effective in the solid cultivation is continuously formed along the cultivation floor. Therefore, it is necessary to make a sag in the transverse direction of the cultivation floor, that is, in the short side direction of the covering material while maintaining an appropriate tension in the longitudinal direction of the covering material along the cultivation floor. Such slack formation is impossible with the multi-laying machine described in Patent Document 2 described above (this prior art creates a slack without applying tension in the longitudinal direction). Thus, fixing right and left ends along the longitudinal direction to the field scene while making an appropriate looseness in the short side direction of the covering material is performed.

  In addition, the cultivation space that is effective in flat cultivation varies in form depending on the type of crop and the shape of the cultivation floor, but when performing manually, different cultivation spaces are uniformly formed according to the type of crop and the shape of the cultivation floor. Therefore, it takes a lot of work, and there is a need for an agricultural covering laying machine that can variably adjust the form of the cultivation space according to the type of crop and the shape of the cultivation floor.

  This invention makes it an example of a subject to cope with such a situation.
