Abstract

PURPOSE:To provide the subject apparatus effective in preventing the peeling of a mulching film from the soil surface and capable of laying the film in high efficiency by thrusting a mulching film into a pushing groove formed on a soil surface of a groove, etc., and collapsing the film thrust in the groove. CONSTITUTION:The objective apparatus is provided with a thrusting wheel 3 to push the upper surface of a mulching film 1 covering the soil surface into a pushing groove 2 formed on the soil surface and a pressing wheel 4 placed at the back of the thrusting wheel 3 and pressing the upper surface of the thrust mulching film 1 to collapse the pushing groove 2.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a mulch film laying device.

The mulch film 1 that covers the upper surface of the soil is pushed into a groove formed on the soil surface, etc., and the pushed mulch film is crushed together with the soil surface to be sandwiched in the soil. This is intended to prevent the mulch film from peeling off from the soil surface and allow the mulch film installation work to be carried out with high efficiency.

(Prior art and problems to be solved by the invention) In order to prevent the mulch film from peeling off when it is laid on the soil surface, a part of the soil is placed on top of the mulch film or wrapped around a part of the mulch film. Although there are various forms, the structure, functions, etc. are complicated and inefficient.

(Means for solving the problem) This invention provides a mulch film 1 to be laid covering the soil surface.
A pushing wheel 3 that pushes the upper surface into the pushing groove 2 formed on the soil surface, and a pressing ring 4 located at the rear of the pushing wheel 3 that presses the upper surface of the film after pushing the mulch film 1 and crushes the pushing groove 2. The structure of a mulch film laying device includes:

(Operation and Effect of the Invention) While forming push grooves 2 along appropriate positions on the soil surface, mulch film 1 is laid so as to cover the upper surface of the push grooves 2, and a push wheel 3 is used to push the mulch film from above the push grooves 2. 1 into the pushing groove 2. The mulch film 1 in this pushing groove 2 is folded in half, and when this pushing groove 2 is crushed from the left and right sides by the pressing shaft 4 from the upper surface, it is in a state of being pinched between the pushing grooves 2 and upwards. This prevents it from coming off when removed.

In this way, the mulch film 1 is pushed into the push groove 2 from the upper surface by the pushing ring 3, and the pressing shaft 4 presses down from the top surface of the mulch film 1 to crush the 2 parts of the pushing groove. Since the actions of the mulch film 3 and the suppressing wheel 4 are performed from the upper surface of the mulch film 1 immediately after coating, the action can be performed at high speed in a stable state, and peeling of the mulch film 1 can be reduced.

(Example) In FIGS. 1 and 2, reference numeral 5 denotes a crushing soil cultivating device, which is connected to the rear side of the tractor body through a connecting portion 6, and is transmission driven by an interlocking connection of an input shaft 7. This tillage device 5
A plurality of cultivators 8 are arranged on the rear side, and a groove cutter 9 is provided at the rear of the central part of each cultivator 8 to cut a push groove along the center part of the groove part B between the cultivated soft parts A. form 2. A film reel 10 on which a roll of mulch film 1 made of a vinyl sheet or the like is wound and supported is positioned above each soil chain part A and groove part B on the top of the soil cultivator 8. While pulling out the film 1, the entire surface is covered over the upper surface of the chain portions A and groove portions B formed on the soil surface.

Reference numeral 11 denotes a guide roll made of a sponge roll or the like rotatably provided on the rear upper side of each cultivator 8.

Furthermore, at the rear of this soil cultivator 8, a pushing wheel 3 and a pressing shaft 4 are disposed in each groove B. The pushing ring 3 has a disc shape and is rotatably mounted on the machine body, and is configured to face the rear of each groove cutter 9 and to bite into the push groove 2 formed by the groove cutter 9. There is.

Further, the pushing ring 3 may be mounted so as to be slightly inclined to either the left or right side. In the rotation, the pushing ring 3 at the center in the left-right direction is tilted.

Further, the pushing ring 3 at the center is provided in front of the pushing wheels 3 on both the left and right sides, and the suppressing ring 4 provided at the rear of one side of each pushing ring 3 and the suppressing shaft 4 at the center are , is provided at a position close to the pushing ring 3, but the pressing wheels 4 on both left and right sides are provided at positions slightly rearwardly away from the pushing ring 3 on the outside.

When the tiller 5 plows the soil while moving the machine forward, and the soil is cultivated using the soil cultivator 8, chain portions A and groove portions B are formed. A pushing groove 2 is formed in the center of the width of each groove B by a groove cutter 9, and at the same time, the mulch film 1 is pulled out from the reel 10 and guided by the guide roll 11, each pushing ring 3, the pressing shaft 4, etc. Meanwhile, the upper surfaces of the chain parts A and the groove parts B are covered, and in each pushing groove 2, the pushing ring 3 that presses from the upper surface of the mulch film 1 folds a part of this mulch film 1 into the pushing groove 2. In order to further press down the soil surface of the groove B into which the mulch film 1 has been pushed, the pressing shaft 4 presses it.
The pushing groove 2 into which the mulch film l has been pushed is crushed by the pushing ring 3.

The mulch film 1 in the push-in groove 2 is folded in half and is held between the soil from the left and right sides, and is prevented from being pulled out from the push-in groove 2.

In laying such a mulch film 1, when each pushing wheel 3 pushes into the pushing groove 2, since the pushing wheel IIa3 in the center is on the advancing direction side with respect to the left and right pushing wheels 3, there is no back and forth in the pushing action. As a result of this, the mulch film 1 tends to be pulled in the lateral direction. First, when the pushing wheel 3 in the center is in the pushing position, the mulch film 1 on both the left and right sides are pulled toward the center. After that, when pushing with the pushing wheels 3 on both the left and right sides, the part of the mulch film 3 pushed in at the center is held as it is by the action of the N pushing wheels 3, the pressing shaft 4, etc. Because of this condition, only one part of the outer mulch film is pulled toward the left and right pushing wheels 3 side without being pulled toward the left and right outside, and the pushing action into the pushing groove 2 and pressing fixation are performed. becomes. For this reason, the mulch film 1 can be stably laid without each pushing ring 3 re-dragging the portion of the mulch film 1 that has been once embedded in the pushing groove 2.

In addition, by changing the pushing pressure of the pushing ring 3 between the central part and the left and right sides, and applying a pressure difference such as a pressure spring, so that the pushing ring 3 in the center part is strong and the pushing ring 3 in the center part is strong, and the pushing ring 3 is weak on both left and right sides. This makes it possible to smoothly pull the mulch film 1 into the push-through groove 2 and maintain stable pushing.

In Figures 3 to 5, the difference from the upper side is that reel 1
A guide roll 12 is placed in the center between the o and the guide roll 11.
Guide rods 13 are provided on both left and right sides, and the guide rods 13 are curved so that the outer side recedes, and the mulch film 1 is pulled out rearward while expanding outward.

Also, the mulch film 1 that is pulled out under tension in this way
The left and right end edges of are held down by stabilizing shafts 14 made of sponge rolls or the like provided at the outer front parts of the left and right outer pushing wheels 3,
The outer edge portions of the mulch film 1 are prevented from flapping due to wind pressure, and the pushing wheels 3 and suppressing wheels 4 on the left and right outer portions are guided to accurately perform the laying action.
