A pair of rotary blades 105 projecting from both sides are disposed in front of the body 103 in the traveling direction, and are driven to rotate in a direction opposite to the traveling direction by a motor mounted on the body 103. A gutter 107 for guiding the soil is provided on both sides in a direction in which the soil is flipped up, and a tip of the gutter 107 is arranged above the lateral crop. With such a configuration, the soil excavated and jumped up by the rotary blade 105 is blown toward the gutter 107, guided to the upper part of the crop by the gutter 107, and dropped from the tip.

[0003]

According to the above-mentioned conventional configuration, there are the following problems. First, there is a problem that the excavated soil cannot be stably dropped to an arbitrary place by a predetermined amount. In other words, in the conventional one, the soil is fed into the gutter using the power of the rotary blade to jump up, so that the supply of the soil becomes unstable. It could not be supplied. Also, it is good if the soil in the work place is dry,
In the case of wet soil, there has been a problem that the jumped soil adheres to the gutter, and the gutter is clogged, making it impossible to work.

The present invention has been made based on such a point, and an object of the present invention is to be able to reliably supply excavated soil to an arbitrary position in a predetermined amount regardless of the distance to a crop. An object of the present invention is to provide a soil covering machine capable of reliably performing work even on wet soil.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a soil covering machine according to the present invention has a traveling body, a self-propelled body, a rotary blade mounted on the body and tilling the ground, and a tilling cultivated by the rotary blade. An introduction passage for introducing the soil that has been jumped up and down, a passage for receiving the soil from the introduction passage and guiding the soil to the side of the body, a screw blade, a bucket conveyor, or a belt provided in the passage and driven to rotate. And a soil discharging mechanism comprising a conveyor.

[0006]

[Function] First, the ground is plowed by the rotary blade, and the plowed soil is flipped up. This soil is introduced into the passage by the introduction passage. The soil that has entered the passage is drawn out along the passage that is forcibly guided to the side of the fuselage by the soil discharge mechanism, carried to a predetermined position, and dropped from the end of the passage. Therefore, the soil can be surely dropped to a desired position. Further, even when the soil is wet, the soil is forcibly carried out by the soil discharge mechanism, so that the soil covering operation can be performed reliably.

A rotary blade 9 is mounted on the front side of the body 1 in the traveling direction. This is attached to the front side of a chain case 11 extending obliquely downward from the machine body 1, and is formed so that its blade bites into the ground. In addition, an introduction passage 13 is formed above the rotary blade 9. The introduction passage 13 includes a cover 15 attached to cover the upper part 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 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 body 1.
The passage 19 has a gutter shape, and has a front surface opened to receive the jumped-up soil, and extends therefrom on both sides of the body 1.

In the passage 19, a soil discharging mechanism 21 is provided. That is, the rotary shaft 23 horizontally arranged in the passage 19 has the screw blade 2
5, 27 are attached. Screw blade 25, 27
Means that the screw surfaces are inclined outward, respectively,
By the rotation of 3, the soil that has entered the passage 19 is forcibly carried out along the screw surface.

A rear plate 29 is attached to the rear of the rotary blade 9 below the body 1 so as to prevent soil from entering behind the rotary blade 9. In the center of the lower part of the back plate 29, the residual tillage treatment device 3 is provided.
1 is attached. This is a rotary blade 9
In this case, the remaining tillage processing plate 35 is attached to a shaft 33 projecting from the back plate 29 in the traveling direction of the body 1 so as to face down. The residual cultivation processing plate 35 is configured so that the power of the prime mover 3 is transmitted and reciprocatingly rotates.

In front of the rotary blade 9, the traveling wheel 3 is provided.
The rotary blade 9 is provided with a height adjustable and the tillable depth of the rotary blade 9 can be adjusted.

Next, the rotary blade 9 and the soil discharge mechanism 2
1 and the drive system of the residual tillage treatment device 31 will be described with reference to FIG. First, a first intermediate shaft 39 horizontally disposed in a direction perpendicular to the traveling direction of the body 1 is supported at the center of the body 1, and is disposed at a lower portion of the body 1 in the same direction as the above. A second intermediate shaft 41 is supported.

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

A rotary shaft 57 of the rotary blade 9 is axially supported in front of the body 1 in the same direction as the second intermediate shaft 41.
A chain 6 is provided between a sprocket 59 attached to the intermediate shaft 41 and a sprocket 61 attached to the rotary shaft 57.
Hang 3 As a result, the rotation of the motor 3 is

Further, the first intermediate shaft 3 is provided on the upper part of the body 1.
9 and a sprocket 65 attached to the first intermediate shaft 39 for supporting the rotation shaft 23 of the soil extraction mechanism 21 disposed in the same direction as the sprocket 65.
A chain 69 is suspended between the rotating shaft 23 and a sprocket 67 attached to the rotating shaft 23. Thus, the rotation of the prime mover 3 is transmitted to the rotation shaft 23.

As for the rotary blade 9, the rotary shaft 5
7 is horizontally extended, and a tilling blade is attached thereto. The rotary blade 9 is driven to rotate so as to flip up the cultivated soil upward. Further, with respect to the soil discharge mechanism 21, the screw blades 25 and 27 attached to the rotary shaft 23 via the first intermediate shaft 39 are driven to rotate.

In the residual tillage treatment device 31, a crank 71 is attached to the second intermediate shaft 41, while the arm 33 is attached to the shaft 33 of the residual tillage treatment plate 35 in a direction substantially horizontal in a direction perpendicular thereto. And the crank 71 and the arm 73 are connected via a crank arm 59. The rotation of the second intermediate shaft 39 swings the arm 73 via the crank 71 and the crank arm 75, and causes the shaft 33 and the residual tillage processing plate 35 attached to the arm 73 to reciprocate.

The operation of the above configuration will be described with reference to FIGS. First, the prime mover 3 is started, and its rotation is transmitted to the wheels 7 to cause the body 1 to travel. In addition, the rotation of the motor 3 is transmitted to the rotation shafts 57 and 23, and the rotary blade 9 and the soil extraction mechanism 21 are rotationally driven. 35 is reciprocated.

In this state, the earth covering machine is run between crops to continuously perform earth covering work. First, the rotary blade 9 is driven to rotate to plow the ground, and the soil is flipped up. This soil is received by the introduction passage 13 in the gutter-like passage 19. Then, it is forcibly carried to the side of the body 1 along the passage 19 by the soil discharge 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 the position where the soil will be dropped.

The excavated soil that does not enter the passage 19 falls, but does not enter the rear by the back plate 29, but is flipped up again by the rotary blade 9 and supplied to the passage 19 side. The amount of soil supplied is adjusted by changing the number of revolutions of the rotary blade 9 or the like. In the center of the lower portion of the back plate 29, a residual tillage treatment device 31 is attached, and the residual tillage treatment plate 35 makes a reciprocating pivotal motion to break down the untiled portion between the rotary blades 9.

According to this embodiment, the following effects can be obtained. First, the excavated soil can be stably dropped to an arbitrary place by a predetermined amount. this is,
This is because the soil flipped up by the rotary blade 9 is guided in the introduction passage 13 and received in the passage 19, and is forcibly carried out along the passage 19 by the soil discharge mechanism 21. This is because the soil can be continuously dropped, and even when the distance is long, the soil can be reliably supplied by setting the passage 19 long.
In addition, even in the case of wet soil, the jumped-up soil can be removed by the soil extraction mechanism 2.
1, the work can be forcibly carried out, so that there is no risk of clogging and the work can be performed reliably.

The earth covering machine of the present embodiment has the following effects in earth covering work of various crops. First, FIG. 5 shows the case of tobacco. In this case, a hole 79 is made in the ridge 77 and a pot seedling 81 is planted. However, if the bot seedling 81 is simply put in the hole 79, it easily falls down due to the wind. , It is necessary to put the soil around and harden, but in this embodiment, since the soil can be reliably supplied to the target position,
This soiling operation can be performed reliably.

FIG. 6 shows a case of chrysanthemums. In this case, soil is dropped on portions between the chrysanthemums (indicated by reference numerals 83 and 85 in the figure). Even if the distance is long, the soil can be buried, and the soil can be dropped to an arbitrary position even when the number of strips is large. FIG. 7 shows the case of green onion. In this case, the height of the ridge 87 is high, and the soil easily accumulates at the corner of the ridge even when the soil is flipped up (shown by 89 in the figure). According to this embodiment, the soil can be reliably dropped on the central portion of the ridge 87 (indicated by reference numeral 91 in the figure), so that the green onion can be accurately covered.

The present invention is not limited to the above embodiment. First, the length of the passage 19 can be adjusted. FIG. 8 shows this example, in which a gutter-like passage 93 of substantially the same shape is fitted into the inner surface of the gutter-like passage 19, and the length of the passage 19 is made variable by pulling it out. Thereby, the position at which the soil is dropped can be arbitrarily adjusted.

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 drawing, the tubular passage 95 may be formed in a bellows shape so as to be able to expand and contract, and the length may be variable.
Further, the passage 19 may be shifted in the front-rear direction as long as it is on the side of the body.

As shown in FIG. 10, the soil extraction mechanism 21 is extended to both sides of the airframe 1 and the screw blade 9
7 may be inclined to one side and may be led out to only one side of the body 1.

As the soil discharge mechanism 21, any mechanism capable of forcibly discharging the soil may be used, and a mechanism using a screw blade, a bucket conveyor type, a belt conveyor type, or the like may be used.

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

[0029]

As described in detail above, according to the soil covering machine of the present invention, excavated soil can be reliably supplied to an arbitrary position in a predetermined amount regardless of the distance to the crop, and even in the case of wet soil. Work can be done reliably.
