Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for laying a marochi film, and is used by being pulled by a traveling vehicle body.

BACKGROUND ART Problems to be solved by the prior art and the invention On a rear portion of a tilling device having a detachable portion that can be attached to and detached from a rear portion of a traveling vehicle body, a molding device that forms a ridge together with tilling by the tilling device, For example, in a multi-film laying apparatus in which a covering device capable of covering a ridge surface with a multi-film and a covering disk for covering soil for locking on left and right side edges of the laid film 6 are provided. When the tilling device is mounted on the rear part of the tilling device, the ground condition of the tilling device is a state in which the tip of the tilling blade of the tilling device itself and the lower end portion of the forming device are installed, so that the ground stability is poor. It is difficult to perform smoothly. Further, since the forming device is usually made of a thin iron plate, there is a possibility that a part of the forming device may be damaged due to a load or instability at the time of grounding.

Means for Solving the Problems The present invention provides a forming device 4 for forming a ridge together with the tilling by the tilling device 3 on a rear portion of a tilling device 3 having a detachable portion 2 detachable from a rear portion of the traveling vehicle body 1. A coating device 5 capable of coating the formed ridge surface with the multi-film 6,
In a multi-film laying apparatus provided with soil covering discs 7 and 7 for covering soil for locking on the left and right side edges of the laid film 6, a vertically rotatable supporting the covering discs 7 and 7 is provided. Between the support rod 8 and the fixed-side support member 9 that rotatably supports the support rod 8, the lower peripheral edge of the covering discs 7, 7 is lower than the lower end of the molding device 4. The multi-film laying apparatus is characterized in that a locking tool 10 capable of locking the support rod 8 is provided in such a state.

When the traveling vehicle body 1 travels, the surface of the ridge, which is formed by the forming device 4 while being plowed by the tillage device 3, is covered with the multi-film 6 by the covering device 5, and the left and right sides of the laid film 6 are covered. The soil is covered on both side edges by soil covering disks 7, 7 that follow the ground while swinging up and down.

When the tilling device 3 is attached to and detached from the traveling vehicle body 1, when the support rod 8 of the soil covering disks 7, 7 is locked to the support member 9 by the locking tool 10, the tilling device 3 and the soil covering disks 7, 7 Is grounded, and the molding machine 4 is not grounded. In this state, the cultivator 3 may be removed or attached to the rear part of the traveling vehicle body 1 or the mounting operation may be performed. It is only necessary to release the stop.

Effects of the Invention Due to such an operation, as described above, when the tilling device 3 is attached to and detached from the traveling vehicle body 1, the tilling device 3 may be grounded by the tip of the tilling blade of the tilling device itself and the forming device. No, since the tip of the tilling blade of the tilling device and the earthing discs 7, 7 are grounded and the molding machine 4 is not grounded,
The distance between the two grounding portions is long and the stability to the ground is good, so that the detaching operation is facilitated. Further, since the molding machine 4 is not grounded, there is no possibility that a part of the molding machine 4 may be damaged.

A right-angled square pipe 20 pin-connected to the hitch portion 19 is provided on a hitch portion 19 having a U-shape in a side view provided at a rear end portion of the frame 14. , A support member having a hexagonal pipe 9a in the left-right direction at the lower end
The hex pipes 9a and 9b are connected to each other, and a hexagonal pipe 9b inserted through and supported by the hexagonal pipes 9a, 9a is supported by a forming unit 4 for forming a ridge together with tilling by the tilling blades 16, 16,. The front side plate is provided with a plowing depth adjustment wheel 21 supported by a vertically movable support member 21a.

A support member 22 erected at the left and right central portions of the square pipe 20 has a fitting member 23 which is fitted to the support member 22 so as to be vertically adjustable.
And a connecting rod 23a connecting the same fitting member 23 located behind the fitting member 23, and the rear fitting member 23 has a left-right support rod 24 at the lower end. The mounting rod 24a of the coating device 5 is fitted so as to be vertically adjustable, and upper and lower ends of arms 24b, 24b supporting the roll-shaped multi-film 6 are connected to left and right ends of the supporting rod 24, respectively. On the upper side of the support rod 24, a pair of left and right supports 26, 26 which are curved rearward and have a front end portion on which a guide roller 25 for guiding the feeding of the multi-film 6 is supported, are provided. At the front ends of the supports 26, 26, a pair of left and right guide bars 26a, 26a for guiding the multi-film 6 along the slope of the ridge is projected.
