Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil cover machine, and more particularly,
It relates to the one that allows the dug soil to be forcibly dropped to a predetermined place.

[0002]

2. Description of the Related Art A soil-covering machine is used for filling auxiliary soil into crops planted on ridges or flat land.
The configuration was as shown in 1. First, the traveling body 101
There is a machine body 103 that can be traveled by, and a pair of rotary blades 105 projecting on both sides are arranged on the front side in the traveling direction of the machine body 103, and are driven to rotate in a direction opposite to the traveling direction by a prime mover attached to the machine body 103. Gutters 107 for guiding the soil are provided on both sides in the direction in which the soil is bounced up, and the tip of the gutter 107 is arranged above the lateral crops. With such a configuration, the soil excavated and flipped up by the rotary blade 105 is blown toward the gutter 107, guided by the gutter 107 to the upper part of the crop, and dropped from the tip.

[0003]

The above-mentioned conventional structure has the following problems. First, there was a problem that the excavated soil could not be stably dropped to an arbitrary place by a predetermined amount. In other words, the conventional one sends the soil to the gutter by utilizing the force of the rotary blade to bounce up, so the supply of soil becomes unstable, and if the dropping distance becomes long, the bounce up force becomes insufficient. It could not be supplied. Also, it is good if the soil in the work place is dry,
In the case of moist soil, there was a problem that the soil that had been lifted up adhered to the gutter, which clogged the gutter and made it impossible to work.

The present invention has been made on the basis of such a point, and an object of the present invention is to reliably supply the excavated soil to an arbitrary position by a predetermined amount regardless of the distance to the crop. (EN) It is an object to provide a soil cover machine that can reliably perform work even on wet soil.

[0005]

In order to achieve the above-mentioned object, a soil-covering machine according to the present invention is a self-propelled machine equipped with a traveling body, a rotary blade attached to the machine body for plowing the ground, and a plowing machine with the rotary blade. A passage for introducing the soil that has been bounced up, a passage provided on the secondary side of the introduction passage for receiving the soil and guiding the soil to the side of the airframe, and a lead-out mechanism provided in the passage for forcing the soil And is provided.

[0006]

[Operation] First, the rotary blade cultivates the ground, and the cultivated soil is flipped up. This soil is introduced into the passage provided on the secondary side by the introduction passage. The soil that has entered the passage is guided out along the passage that is forcibly guided to the side of the machine body by the guiding mechanism, is carried to a predetermined position, and is dropped from the tip of the passage. Therefore, the soil can be reliably dropped to the desired position. Further, even when the soil is wet, the soil can be forcibly carried out by the pull-out mechanism, so that the soil can be surely covered.

A rotary blade 9 is attached to the front side in the traveling direction of the machine body 1. This is attached to the tip side of a chain case 11 extending obliquely downward from the machine body 1, and its blade edge is formed so as to bite into the ground. An introduction passage 13 is formed above the rotary blade 9. The introduction passage 13 has a cover 15 attached to cover the upper portion of the rotary blade 9 and the body 1
And a cover 17 that covers the front surface of the rotary blade 9, and has a function of guiding the soil that has been flipped up by the rotary blade 9. or,
On the secondary side (upper rear side) of the introduction passage 13, a passage 19 is formed which is arranged in a direction orthogonal to the traveling direction of the machine body 1. The passage 19 has a gutter-like shape, and the front surface of the passage 19 is opened to receive the soil that has been flipped up, and the passage 19 is formed to extend to both sides of the airframe 1 from there.

The passage 19 is provided with a drawing mechanism 21 for forcibly discharging the soil. That is, screw blades 25 and 27 are attached to both sides of the rotating shaft 23 arranged horizontally in the passage 19 with the central portion as a boundary. The screw blades 25 and 27 have screw surfaces inclined outwardly, and by rotation of the rotary shaft 23, soil that has entered the passage 19 is forcibly carried out along the screw surfaces to the outside.

A rear plate 29 is attached to the lower part of the machine body 1 at the rear of the rotary blade 9 to prevent soil from entering the rear of the rotary blade 9. Further, at the center of the lower part of the back plate 29, the residual tillage treatment device 3
1 is attached. This is a rotary blade 9
The unplowed part of the chain case 11 is pushed down, and the residual plow plate 35 is attached to the shaft 33 protruding from the rear plate 29 in the traveling direction of the machine body 1 downward. The residual tillage treatment plate 35 is configured to perform reciprocating rotary motion by transmitting the power of the prime mover 3.

In front of the rotary blade 9, the traveling wheel 3
7 is attached, and the height of the rotary blade 9 is adjustable so that the plowing depth of the rotary blade 9 can be adjusted.

Next, the rotary blade 9 and the lead-out mechanism 19
The drive system of the residual tillage processing device 31 will be described with reference to FIG. First, a first intermediate shaft 39, which is horizontally arranged in a direction orthogonal to the traveling direction of the machine body 1, is pivotally supported in the center of the machine body 1, and is arranged in the lower part of the machine body 1 in the same direction as described above. The second intermediate shaft 41 is pivotally supported.

A chain 49 is suspended between a sprocket 45 attached to the output shaft 43 of the prime mover 3 and a sprocket 47 attached to the first intermediate shaft 39. Further, the chain 55 is suspended between the sprocket 51 attached to the first intermediate shaft 39 and the sprocket 53 attached to the second intermediate shaft 41. As a result, the rotation of the prime mover 3 is transmitted to the first intermediate shaft 39 and the second intermediate shaft 41.

Further, in front of the machine body 1, the rotary shaft 57 of the rotary blade 9 is axially supported in the same direction as the second intermediate shaft 41, and
Between the sprocket 59 attached to the intermediate shaft 41 and the sprocket 61 attached to the rotating shaft 57, the chain 6

Communicate to.

Further, on the upper part of the machine body 1, the first intermediate shaft 3 is provided.
9, the rotation shaft 23 of the derivation mechanism 21 is rotatably supported, and the chain 69 is suspended between the sprocket 65 attached to the first intermediate shaft 39 and the sprocket 67 attached to the rotation shaft 23. .. As a result, the rotation of the prime mover 3 is transmitted to the rotary shaft 23.

Regarding the rotary blade 9, the rotary shaft 5
No. 7 is projected horizontally, and a plowing blade is attached here. The rotary blade 9 is rotationally driven so that the tilled soil is flipped up. Further, in the lead-out mechanism 21, the screw blades 25 and 27 attached to the rotating shaft 23 are rotationally driven via the first intermediate shaft 39.

In the surplus tillage treatment apparatus 31, a crank 71 is attached to the second intermediate shaft 41, while the shaft 33 of the surplus tillage treatment plate 35 is provided with an arm 73 in a direction substantially orthogonal thereto. The crank 71 and the arm 73 are connected via a crank arm 59. The rotation of the second intermediate shaft 39 causes the arm 73 to swing via the crank 71 and the crank arm 75, and causes the shaft 33 and the residual tillage treatment plate 35 attached thereto to reciprocally rotate.

The operation will be described with reference to FIGS. First, the prime mover 3 is activated, and its rotation is transmitted to the wheels 7 to drive the machine body 1. Further, the rotation of the prime mover 3 is transmitted to the rotary shafts 57 and 23 to drive the rotary blade 9 and the lead-out mechanism 21 to rotate, and the crank 7
1. The arm 73 is swung via the crank arm 75 to reciprocally rotate the residual tillage treatment plate 35.

In this state, the soil covering machine is run between the crops to continuously perform soil covering work. First, the rotary blade 9 is rotationally driven to cultivate the ground and flip the soil upward. This soil is received in the gutter-shaped passage 19 by the introduction passage 13. Then, it is forcibly carried to the side of the machine body 1 along the passage 19 by the lead-out mechanism 21 arranged in the passage 19 and falls from the tip of the passage 19. The position of the tip of the passage 19 is set in advance at the position where the soil is dropped.

Further, of the excavated soil, those that do not enter the passage 19 fall, but do not enter rearward by the back plate 29, and are rebounded up by the rotary blade 9 and supplied to the passage 19 side. The amount of soil supplied is adjusted by changing the rotation speed of the rotary blade 9. Further, a residual tillage treatment device 31 is attached to the center of the lower part of the back plate 29, and the residual tillage treatment plate 35 makes a reciprocating rotary movement to push down the uncultivated portion between the rotary blades 9.

According to this embodiment, the following effects can be obtained. First, it is possible to stably drop the excavated soil to an arbitrary place by a predetermined amount. this is,
This is because the soil repelled by the rotary blade 9 is guided by the introduction passage 13 and received by the passage 19 and is forcedly carried out along the passage 19 by the derivation mechanism 21. This is because the soil can be continuously dropped, and even if the distance is long, the soil can be reliably supplied by setting the passage 19 to be long. or,
Even in the case of wet soil, the soil that has been lifted up can be forcibly carried out by the pull-out mechanism 21, so there is no risk of being clogged, and reliable work can be performed.

Further, the soil covering machine of the present embodiment has the following effects in soil covering work for various crops. First, FIG. 5 shows the case of a cigarette. In this case, a hole 79 is made in the ridge 77 and a pot seedling 81 is planted here. However, if the bot seedling 81 is put in the hole 79, it is easy to fall by the wind. , It is necessary to put the soil around and harden it, but in this embodiment, the soil can be reliably supplied to the target position,
This soil filling work can be reliably performed.

Further, FIG. 6 shows a case of chrysanthemums. In this case, the soil is dropped on a portion (indicated by 83 and 85 in the figure) between a plurality of rows of chrysanthemums. For example, soil filling work can be performed even when the distance is long, and soil can be dropped at any position even when the number of rows is large. Further, FIG. 7 shows the case of green onions. In this case, the height of the ridge 87 is high, and even if the soil is flipped up, the soil is likely to be accumulated in the corner of the ridge (indicated by 89 in the figure). According to this embodiment, the soil can be reliably dropped onto the central portion of the ridge 87 (indicated by 91 in the figure), so that the soil can be accurately covered with the onion.

The present invention is not limited to the above embodiment. First, the passage 19 can be formed so that its length can be adjusted. FIG. 8 shows this example, in which a gutter-shaped passage 93 of substantially the same shape is fitted into the inner surface of the gutter-shaped passage 19 and is pulled out to make the length of the passage 19 variable. Thereby, the position where the soil is dropped can be adjusted arbitrarily.

As for the passage 19, as shown in FIG. 9, a portion other than the portion for receiving the soil may be a tubular passage 95. Further, as shown in the figure, the tubular passage 95 may be formed in a bellows shape so that it can be expanded and contracted to have a variable length.
Further, the passage 19 may be displaced in the front-rear direction if it is on the side of the machine body.

As for the pulling-out mechanism 21, as shown in FIG. 10, in addition to pulling out on both sides of the machine body 1, screw blades 97
May be inclined to one side and may be led out to only one side of the machine body 1.

The pulling-out mechanism 21 is not limited as long as it can forcibly pull out soil, and may be a screw conveyor, a bucket conveyor type, a belt conveyor type, or the like.

Further, the rotary blade 9 may be positioned rearward with respect to the traveling direction of the machine body 1, and the rotating direction of the rotary blade can be arbitrarily set by using a forward / reverse rotary or the like.

[0029]

As described above in detail, according to the soil cover machine of the present invention, it is possible to reliably supply the excavated soil to any position by a predetermined amount regardless of the distance to the crop, and even in the case of wet soil. You can work reliably.
