Description

DETAILED DESCRIPTION OF THE INVENTION The present invention combines a plow equipped with a plow tip for cutting midway and a guiding surface following the plow, and a soil crushing device that crushes soil by rotating a soil crushing blade provided around a rotating shaft. This invention relates to an improvement in a multi-purpose agricultural work machine that simultaneously plows and crushes soil by crushing the soil that has been plowed and reversed with a plow.

As a tillage and crushing compound work machine that combines a plow and a soil crushing device with rotating soil crushing blades, the soil plowing device crushes the soil plowed by the plow. The crushing blade of the soil crushing device acts in the upward direction from the back side of the soil that is being guided by the soil that is rising, or the soil that is in the process of being turned over, and the soil that is on the guiding surface of the plow. The soil crushing blade that rotates against the plow acts in the down-cut direction to scoop up and crush the soil, and when the plow is plowing and reversing the soil, the plow moves in one stroke. Soil that has been plowed and reversed is crushed by a soil crushing device, and soil that is plowed by a plow and reversed by induction as described in Japanese Patent Publication No. 39-15201.
Various types of soil are known, such as those in which the soil collides with an earthen crusher while it is falling after inversion, so that the soil falls as finely crushed soil. However, all of these conventional methods consist of soil that has been plowed with a plow.
No efforts have been made to eliminate the voids that occur between the two soils, resulting in many large voids between the soil and the soil, cutting the capillary tubes and causing poor moisture retention. There is. In addition, the efficiency of finely crushing the upper layer of soil that has been reversed tillage is poor, and there is a problem that the two operations of reversing tillage and crushing the soil cannot be carried out efficiently at the same time. In addition, there is a problem in that the soil in the field tends to shift to one side of the field due to the lateral movement of the soil that occurs when the soil is turned over. The present invention
This was done in order to solve these problems, and was completed based on the knowledge obtained through various studies aimed at solving these problems.

That is, in the conventional means, as mentioned above, the soil crushing device is used to move the soil that is being plowed and reversed with a plough or plow in a direction that lifts it, or the soil that is falling is suspended in the air. Either it works to crush the soil, or it works on the soil that has been completely turned over by plowing and falling to the ground surface.
When the rotating soil crushing blade is applied to the soil, the rotating soil crushing blade cuts into the soil where the soil being plowed and turned over by the plow has almost finished turning over and begins to land, and When we cut into the soil in that state from the back side of the soil to a depth that does not reach the surface layer in the direction of the down cut, this soil crushing blade is reversed by the plow and lands on the ground surface. The soil that is being turned is pressed against the soil that has already been turned over and is located in the field, and a cut is made between the soil and the soil when the soil is turned over. The result was that large voids were crushed. In addition, when doing this, if the cutting edge of the soil crushing blade is too deep into the turning soil, the soil will not be pushed in enough. The height position of the crushing blade relative to the plow supported on the machine frame can be adjusted by rotating the rotating arm up and down with respect to the machine frame. By adjusting the cutting depth of the soil crushing blade into the soil, the soil that had almost finished inversion and started landing was pressed against the soil that had already been inverted and was placed in the field. The result was that they were able to move on. In addition, a lattice-shaped frame rod is installed above the crushing blade that crushes the soil while pressing the soil, and a rake is suspended from the rear end of the frame rod so as to be able to move up and down. A cover is installed to remove the clods thrown up by the crushing blade.
This lattice-shaped frame rod and the rake at its rear end surround it, and only the soil that collides with the lattice-shaped frame rod and is crushed is pushed up from the lower side of the lattice-shaped frame rod to the upper side, and is covered. By guiding it backwards, the results showed that the surface soil could be crushed into small pieces extremely efficiently.
In addition, when the above-mentioned crushing blade was formed into a spiral shape that caused the soil to flow in the opposite direction to the direction in which the plow reversed the soil by its rotation, it was found that at the same time as the soil was crushed, the soil was reversed. This study was completed based on these findings, as it was possible to prevent the lateral movement of soil in the field.

Therefore, in the present invention, as the first invention, a plow having a plow tip for cutting the soil and a guiding surface following the plow is supported on the machine frame, and a plow is provided at the rear of the plow. A rotating shaft extending along a horizontal direction perpendicular to the direction of travel of the plow in plan view is mounted above the position where the soil rotated by plowing and being guided by the plow almost completes its reversal and begins to land. A crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side, and the rotating shaft is set so that the crushing blade is in the down-cut direction. This invention proposes an agricultural compound working machine that simultaneously performs tillage and soil crushing, characterized in that it is forcibly driven to cut into the soil. A plow equipped with a plow tip for cutting and a guiding surface following the plow is supported, and behind the plow, the soil that is plowed and turned over by the plow is above the position where the turning is almost completed and the soil begins to land. A rotating end of a support arm that supports the machine frame so as to rotate up and down a desired amount by arranging a rotating shaft along a horizontal direction perpendicular to the traveling direction of the plow in a plan view at a position. A crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side, and the rotation is controlled by the crushing blade. The soil crushing blade is forcibly driven to cut into the soil in the downcut direction, and the height position of the soil crushing blade relative to the plow can be adjusted by adjusting the vertical movement of the support arm. In addition, as a third invention, a plow equipped with a plow tip for cutting soil and a guiding surface following the plow is supported on the machine frame, and a plow is provided at the rear of the plow. A rotating shaft that runs in a horizontal direction perpendicular to the direction of travel of the plow in plan view is mounted above the position where the soil that is being plowed and reversed by the plow almost completes its reversal and begins to land. A crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side, and the rotating shaft is set so that the crushing blade is in the down-cut direction. A lattice-shaped frame rod is installed on the upper surface side of the rotary shaft, which is forcibly driven to cut into the soil, and is mounted on the machine frame. A rake is arranged in the shape of a surrounding cover, and a rake is suspended from the rear end of the rake so as to be able to move up and down. He proposed a multi-purpose agricultural work machine that simultaneously plows and crushes soil, which is characterized by a case-shaped cover, and as a fourth invention, a plowhead for cutting soil and a plowhead for cutting the soil on the machine frame. At the same time as supporting a plow equipped with a continuous guiding surface, behind the plow, at a position above the position where the soil that is being plowed and turned over by the plow has almost completed its turning and begins to land,
A rotating shaft extending in a horizontal direction perpendicular to the direction of travel of the plow in plan view is mounted, and a soil crushing blade is mounted around the rotating shaft at a depth where the cutting edge does not reach from the back side to the top side of the soil. A rotary shaft is forcibly driven so that the soil crushing blade cuts into the soil in the down-cutting direction, and the rotary shaft is mounted on the rotary shaft mounted on the machine frame. A complex agricultural work that simultaneously performs plowing and soil crushing, characterized in that the soil crushing blade is formed in a shape that allows the soil to be crushed by the rotation of the rotary shaft to flow in a direction opposite to the direction in which the soil is plowed by the plow. This raises an opportunity.

Next, embodiments will be described in detail with reference to the drawings.

The guide surface 42a of the soil repellent plate 42 is formed in a shape that turns the soil 5 inside out 180 degrees as shown in FIG.

Reference numeral 6 denotes a rotating shaft mounted on the machine frame 1 at the rear of the plow 4 and located above the position where the soil 5 to be plowed and reversed by the plow 4 substantially completes reversal. As shown in FIG. 2, a pair of supporting arms are attached to the supporting machine frame 7, which is provided so as to protrude from the machine frame 1 toward the side where the plow 4 reversely guides the soil 5. Install 8 and 9,
By supporting the support arms 8 and 9 on the protruding ends of the support arms 8 and 9, the machine frame is placed in a horizontal direction that is perpendicular to the traveling direction of the plow 4 (the traveling direction of the tractor B) in plan view. 1 is mounted on a shaft.

Of the support arms 8 and 9, the support arm 8 on the side closer to the machine frame 1 is formed in a conduction case, and has a conduction mechanism (not shown in the drawing) in its inner cavity that communicates with one end of the rotation shaft 6. (not specified) are in the collection.
The transmission mechanism is transmitted through a transmission shaft 60, a transmission gear in a gear case 61 mounted on the machine frame 1, a transmission shaft 62, and a universal joint shaft 63 to a PTO shaft 64 provided at the rear of the body 3 of the tractor B. The rotary power is transmitted from the tractor B side to the rotary shaft 6.
It is now being conducted to in this case,
By incorporating a mechanism into the PTO shaft 64 that increases or decreases the rotation speed according to the running speed of the body 3 of the tractor B, or by providing a speed change mechanism in the middle of the transmission mechanism from the PTO shaft 64 to the rotation shaft 6, the rotation axis 6
so that the speed can be controlled as desired.

Reference numeral 10 denotes a crushing blade to be mounted around the rotating shaft 6, which is formed into a machete-like shape and whose base end is mounted on the circumferential surface of the rotating shaft 6 or the circumferential surface of a shaft cylinder fitted onto the rotating shaft 6. Although it is attached to the metal fitting 11 so as to protrude radially from the rotating shaft 6 as shown in FIG. 4, it may be formed into an appropriate shape. Further, the arrangement state with respect to the rotation axis 6 in a plan view may be designed as appropriate. However, this crushing blade 10
When the rotation of the rotary shaft 6 acts on the soil 5 that has been plowed and reversed by the plow 4, it is to the extent that it does not reach the surface side compared to the back side 50 of the soil (the top side of the reversed soil). Its length is set so that it acts on the depth of . This depth of action is determined by supporting the support arms 8 and 9 so as to be able to rotate up and down relative to the support frame 7, and fixedly supporting the support arms 8 and 9 on the support frame 7 after being rotated by a desired amount. Then, swing the support arms 8 and 9 relative to the machine frame 1 as shown by the arrows in FIG.
The lower edge of the rotation locus of the cutting edge of the soil crushing blade 10 may be adjusted as desired by vertically adjusting it with respect to the plow 4 that can be supported on the machine frame 1. Further, the rotary shaft 6 is such that the crushing blade 10 is connected to the fourth
As shown by the arrow in the figure, the soil 5 is driven and rotated so as to act on it in the downcut direction. The soil crushing blade 10 also has a rake angle at the cutting edge that cuts into the soil 5 so as to scoop up soil clods from the cut soil 5 and flip them upward from the rear (left side in Figure 4). A lateral bend 10a is formed. When this side bent portion 10a cuts into the soil 5 and moves the soil 5, the flow direction of the soil is opposite to the direction in which the soil 5 is guided and reversed by the plow 4. By forming the soil in this way, the movement of soil by plowing can be reversed when the soil is crushed. This soil return is carried out by arranging the soil crushing blades 10 to form a spiral that sends the soil in the returning direction when the soil crushing blades 10 are mounted around the rotating shaft 6. It may be.

b is a lattice-shaped frame rod arranged in a cover-like manner on the upper surface side of the rotary shaft 6 so as to surround the upper part of the rotation locus of the cutting edge of the soil crushing blade 10; It is arranged on the inner surface side of a case-shaped cover c attached to the frame 7 so as to be parallel to the inner surface of the cover c at a predetermined interval, and is suspended and supported by the cover c using appropriate mounting fittings. be. A rake 20 is hung from the rear end of the lattice-shaped frame rod b so as to be able to rotate up and down. Only the soil that is surrounded by b and the rake 20, thrown up, and crushed by colliding with the frame rod b passes through the gap between the frame rods b and is formed between the inner surface of the cover c and the upper surface of the frame rod b. It is designed to be guided to the rear of the rake 20 through a path.

In the illustrated embodiment, reference numeral 21 denotes a flat cover suspended from the rear edge of the cover c so as to be rotatable up and down.

As explained above, the agricultural compound working machine according to the present invention that simultaneously performs plowing and soil crushing has a first invention that includes a plow having a plow tip for cutting the soil and a guiding surface following the plow tip in the machine frame. At the same time as supporting the plow, at the rear of the plow, the soil that is plowed and reversed by the plow is located above the position where the soil that is being plowed and reversed almost completes its reversal and begins to land, and is perpendicular to the direction of travel of the plow in plan view. A rotating shaft running in the horizontal direction is mounted on a shaft, and a soil crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side. Since the rotary shaft is configured to be forcibly driven so that the soil crushing blade cuts into the soil in the downcut direction, the soil crushing blade cuts into the soil that has been reversed by the plow and has begun to land. It is pushed into the side of the soil that has already been turned over and is located in the field, and cuts are made between the soil and the soil when the soil is turned over. The soil was crushed by crushing the large gaps, and the soil was crushed at the same time as the tillage was reversed to keep the soil in a good state of retaining moisture.

In addition, in the second invention, a plow having a plow tip for cutting the soil and a guiding surface following the plow is supported on the machine frame, and behind the plow, the soil is guided to plow by the plow and turned over. A rotating shaft along a horizontal direction perpendicular to the direction of travel of the plow is arranged at a position above the position where the plow almost completes its reversal and begins to land. The rotary end of the supporting arm that is supported for rotation is mounted on a shaft, and the soil crushing blade is mounted around the rotating shaft to a length where the cutting edge cuts into the soil from the back side to a depth that does not reach the surface side. The rotary shaft is forcibly driven so that the soil crushing blade cuts into the soil in the downcut direction, and the height position of the soil crushing blade relative to the plow can be freely adjusted by adjusting the vertical movement of the support arm. Since the support arm is rotated up and down and the height position of the soil crushing blade relative to the plow is changed, the depth of cut of the soil crushing blade into the soil that is being plowed and reversed by the plow can be changed. Since it can be adjusted as desired, the soil can be pushed in effectively by the soil crushing blade.

Further, in the third invention, a plow having a plow tip for cutting soil and a guiding surface following the plow tip for cutting the soil is supported on the machine frame, and at the rear of the plow,
A rotating shaft along a horizontal direction perpendicular to the direction of travel of the plow is mounted above the position where the soil that is being plowed and reversed by the plow almost completes its reversal and begins to land. Then, a crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side, and the rotating shaft is set so that the crushing blade cuts in the down cutting direction. The rotating shaft is mounted on the machine frame, and on the upper side of the rotating shaft, a grid-shaped frame rod is installed above the rotation trajectory of the cutting edge of the soil crushing blade installed on the rotating shaft. A rake is hung from the rear end of the rake so as to be movable up and down, and a rake is placed on the upper surface of the lattice-shaped frame rod at a predetermined distance from the lattice-shaped frame rod. Since the structure is such that the cover is attached in a case-like manner, the soil clods that are thrown up by the crushing blade are surrounded by the lattice-shaped frame rods and rakes, and only the soil that collides with the frame rods and is crushed into small pieces. It escapes upward through the gaps in the lattice-shaped frame rods, and the upper cover causes it to flow behind the rake, effectively crushing the top surface of the soil that has been turned over by plowing.

Further, in the fourth invention, a plow having a plow tip for cutting soil and a guiding surface following the plow tip for cutting the soil is supported on the machine frame, and at the rear of the plow,
A rotating shaft along a horizontal direction perpendicular to the direction of travel of the plow is mounted above the position where the soil that is being plowed and reversed by the plow almost completes its reversal and begins to land. Then, a crushing blade is installed around the rotating shaft with the cutting edge set to a length that cuts into the soil from the back side to a depth that does not reach the surface side, and the rotating shaft is set so that the crushing blade cuts in the down cutting direction. The plow plows a soil crushing blade which is forcibly driven to cut into the soil and which is mounted on a rotating shaft mounted on the machine frame. Because it is configured in a shape that allows it to flow in the opposite direction,
The soil that is being plowed and reversed by the plow is crushed by the soil crushing blades while flowing in the opposite direction to the direction in which the soil is being reversed, making it possible to prevent the soil from moving laterally in the field.
