Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film mulching device capable of performing seed mulching work simultaneously with ridge raising work.

Conventionally, this type of film mulching device, as shown in Fig. 1, has a film winding row (4a) and a sowing machine mounted on a machine frame (8a) extending rearward from a tilling device (not shown). Attach the machine (5a), etc., and remove the film winding roller)v
The arm (10a) is curved so as to surround the outer periphery of (4a).
) At the rear end of the film (6a), two arc-shaped tension rods (9a) are inserted to the left and right so as to sandwich the perforated part of the film (6a). They were distributed and installed. When the sensor (7a) of the seeding machine (5a) falls into the perforated part of this film (6a), the shutter (
7b) is opened, the seeds pass through the perforated part of the film (6a) and are collected in the hopper (lla) installed at the bottom of the film (6a), and then into the seeding groove (18a) formed by the groove maker (3a). It was configured to drop seeds. However, in such a device, since the distance 5 from the seeding drop opening of the seeding machine (5a) to the furrow bottom (seeding bed) is relatively long, the yaw sensor (7a) cannot detect the holes in the film (6a). When the seeds 1 are sensed and dropped into the hopper (lla) and sown in the furrow bottom, the seeds in the furrow bottom do not match the perforated part of the film (6a) that covers them, and the film (6a ) often shifted in front or behind the sown seeds, and this discrepancy was especially severe when mulching on slopes.

Moreover, an arc-shaped tension rod (
9a) was welded to the rear end of the arm (10a), the perforated part of the loosened film (6a) was caught in this welded part, and during the work of laying the film (6a), the film (6a) There was a problem with breaking the .

This invention is proposed in view of the above drawbacks, and includes:
It is an object of the present invention to provide a film mulching device that can smoothly pull out a film from a film take-up roll and perform accurate seeding work.

To avoid this, the present invention has taken the following technical measures.

That is, the film mulching device (1) is equipped with a furrower (3), a film take-up roll (4), and a seeding machine (5) behind the tilling device (2), and the seeding device (5) is , the sensor (7) installed at the bottom of the film winding roll (4)
A pair of left and right tension rods tension the film (6) and are configured to fall into the holes α of the film (6) pulled out from the ground to cause the seeds to fall into the seeding groove α8) formed on the ground surface. (9) (9) is installed close to the ground surface, its central part is curved in the shape of a mountain when viewed from the side, and attached to the machine frame (8), and its lower end is inserted into the seeding groove marked a. The film mulching device is characterized in that the film mulching device is buried in the soil.

Next, one embodiment of the present invention will be described based on the drawings.

At the rear of the tilling device (2), there is a ridge making device α.
is provided. The α force is a cylindrical pressing roller that presses the upper surface of the ridge formed by the ridge forming device H, and on the circumference of this pressing roller α, there is a protruding groove making device for forming the seeding groove θ mark. (3) is integrated with the pressure roller 0'I),
In addition, several spears (two in this embodiment) are provided at appropriate intervals in the lateral direction. 0 theft is the above pressure roller 0
It is a belt-shaped frame surrounding the outer periphery of η, and its front end is pivotally connected to the rear cover 00, and a support rod whose upper part is supported by the machine frame (8) is located at the middle part in the longitudinal direction on the left and right sides of the frame. (A) is attached, and the pressure roller α is configured to elastically press the frame body downward.

A perforated film (6
) is provided with a film take-up roll (4) wrapped with
The film (
6) is once brought into contact with a guide roller Q1) provided near the ridge substantially directly below it, and then fed out. (A) is an arm that supports the left and right sides of this guide roller Q]). (9) (9) is a film (6) fixed to a member extending downward from the machine frame (8).
This tension rod (9) (9) is formed of a round rod, and as shown in FIG.
It is placed close to the front and lower part of the ridge, and its middle part in the front and back direction is curved in a mountain shape when viewed from the side, and the rear end is buried in the soil between the sowing groove α mark formed at the top of the ridge. It is installed as shown.

(5) is a seeding machine supported by a machine frame (8), the lower part of this seeding machine (5) is connected to a tube (c) that guides the seeds to the ridge top, and the lower part of the seeding machine (5) is connected to a tube (2 ) to cut the seeds down into the furrower (
An opening/closing part is configured to allow the film (6) to fall into the groove α8) formed in step 3). When the sensor (7) falls, the opening/closing lid (c) that is integrated with this sensor (7) opens and a certain amount of seeds are placed on the film (6).
Tension rods (9) buried in the soil are inserted between the left and right sides of the sowing groove α8).
) (9) The sloped inner surface of the seeding furrow Qe is broken down at the rear end to cover with soil.

In addition, the code|symbol (c) in a figure is an upper roller which presses the upper part of a film (6), (a) is a urethane wheel which presses the hem part of a film (6), and (a) is a soil covering disk.

Next, the operation of the upper side will be explained.

The soil that has been tilled by the tilling section (13) of the rotary tiller (2) is formed into ridges using the ridge maker 0 behind the tiller section (3) and the pressure roller α force rolling on the top of the ridge. At the same time, grooves are cut using a groove cutter (3) integrated with the pressure roller αη.

Then, when the film mulching device (1) is advanced while pressing the upper and side parts of the film (6) with the upper roller (C) and the urethane wheel (4), the film is pulled out from the take-up row # (4). (6) is always in a tensioned state with no slack, and the sensor (7) that detects the hole θ of the film (6) falls into the hole 0, and is installed at the bottom of the tube of the seeding machine (5). Then, the opening/closing lid (c) is opened, and a predetermined amount of seeds are guided and dropped into the sowing groove 0 frame.

Then, when the film (6) is further pulled out to the rear, the sensor (7), which had fallen into the hole a, is lifted upward by the film (6) and the opening/closing lid is opened.
c) is closed, and then the ridges are covered with the film (6) while matching the hole 02 part of the film (6) with the part of the sowing bed where the seeds have fallen.

At this time, the tension rods (9) (9) supporting the film (6) from below have their front lower portions close to the ridges, and the intermediate portions in the front-rear direction that continue to extend rearward are mountainous when viewed from the side. It is curved in shape, and its lower end forms a seeding groove α.
Since the seeds are buried in the soil with the marks in between, the distance it takes for the seeds to fall and reach the sowing bed that has been cut in the furrow is short.
Since the arrival time is shortened, the position of the sowing part and the hole α part of the film (6) covering it will not shift back and forth during film laying work, and the film tension rod (9) Since covering with soil is also performed at the same time in step (9), efficient seeding and mulching can be achieved.

Since the present invention is configured as described above, it has the following technical effects.

In other words, the tension rod (9) (9) is used to stretch the film (6).
) is provided close to the ridge, and the intermediate part in the front-rear direction of the part that continues to extend rearward is formed in a mountain shape, so that the film ( 6) Wind enters from below and beats the film (6) violently, causing the film (6) to peel off from the top surface of the ridge, so you can always expect a smooth pull-out action of the film (6). In addition, the sensor (7) that slides on the top surface of the film (6) can operate reliably, making it possible to perform accurate seeding work. Therefore, it is possible to perform an efficient seeding and mulching action.

In addition, since the distance that seeds dropped from the sowing outlet of the sowing machine (5) reach the sowing groove α frame that has been created is shortened, when the film (6) is being laid, the sowing area and the film that covers it are removed. The position of the hole (6) matches exactly, and there is almost no deviation even when working on a slope.
