Description

[Detailed description of the device]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a digger for long-root crops that is towed by a motor vehicle such as a tractor.

[0002]

[Technical background]

 It relates to a digging machine for harvesting long root crops such as burdock root and yam, which is driven by a power machine, for example, a working machine towed by a tractor, and which uses a running motion as a working source to harvest with a plowing blade.

[0003]

[Prior art]

 A pair of cultivating columns are installed on the left and right sides of the ridge, centering on the row to be harvested, on both the left and right sides, and the front part is located at the lower end of the cultivating column. A digging machine for long-rooted crops equipped with a plowing blade oriented toward is generally known among breeders of the crops.

Further, in addition to the configuration described above, it is also known that an auxiliary plate called a cleave plate that is directed rearward from an intermediate position at the height of the cultivating pole is mounted. The difference between these forms is properly used depending on the viscosity of soil characteristics using the mining machine.

[0005]

[Problems to be solved by the device]

 As for the action of the tiller-type digging machine mentioned above, the forward-tilting tiller blade is set to operate at a position still deeper than the lower end (tip) position of the long root crop that is the harvested product, By infiltrating this to the set position and running the excavator on a power vehicle such as a tractor, the soil between the two pairs of tillage columns is tilted forward while holding the harvested material. The height difference before and after the tilling blade is raised from the field scene.

[0006] At that time, the soil mass containing the protruding crops is released from the surrounding soil pressure and the migration phenomenon due to the embossing action causes the crops to separate from the surrounding soil masses to facilitate harvesting. There is.

[0007] The above-mentioned action is the ideal action as the digger, however, it is not the case that the total amount of harvest achieves this ideal action. Part of the skin is partially separated from the surrounding soil at the point where it is held by a pair of tillers, and after passing through the tillers, the balance of the weight of the raised portion is broken and it is formed by the raising action. There are many occurrences of the phenomenon that the divided lumps of earth fall into open spaces.

[0008] In this case, the crop is divided at the same time as the divided soil mass, and the commercial value of the crop, which has the full length harvest, is lost at the time of this harvest.

[0009] The damage to crops due to the above-mentioned phenomenon is often found in a type in which an auxiliary piece called a cutting board is attached to the middle of a cultivating column, and various damages are caused in the case without the cutting board. The phenomenon is observed.

In addition, according to the characteristics of a traction motor vehicle such as a tractor that pulls a work device, in steering operation, although the steered wheels are front wheels, the rear wheels cause a lateral flow in a direction opposite to the steering direction of the front wheels. In the case of a long-root crop digging machine, which has a tendency to wake up and is a direct connection type between the tractor and the working machine and has no pivot point at the connection part, it is possible to double the phenomenon of the rear wheels flowing out and It is not uncommon for the facing cultivator to move sideways with the outflow of the rear wheel, thereby contacting the unharvested soil crops and damaging the crops before digging.

The present invention is a mining machine for long-rooted crops, in which the crop and the soil surrounding the crop are placed above the ground level while the whole shape of the crop is intact and there is no damage. When the tractor is steered, the crop and soil mass are easily separated when separated from the digger, facilitating separate harvesting of the crop alone, and the steering direction of the steering disc when steering the tractor. The purpose is to maintain the normal value of the tilling locus by operating in the same direction to add resistance to the action of the rear wheels of the tractor to laterally slide out.

[0012]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention provides a hitch connecting member at the tip and a cultivating column equipped with a cultivating blade at the rear end in a digger for long-rooted crops. The steering frame is hung in the middle of the mounted frame, and the steering member rotatably attached to the steering disk is rotatably supported. The handle is attached so that its tip points rearward.

[0013]

[Embodiment of the invention]

 The forward-tilting plowing blade has the effect of submerging in the soil due to the traveling action that is pulled, but it is maintained by regulating the traveling depth position to a constant state by the plowing pillar supporting the plowing blade. .

These cultivating pillars and a pair of cultivating pillars that oppose each other by running by pulling the cultivating blade demarcates a strip-shaped range having a relatively small width in which the crop to be harvested is placed in the center of the gap. Each of the plowing blades that are split in the middle direction and installed at the lower end of the cultivating column in a forward tilted state and in parallel position has the line connecting the tips of the plowing blades maintained substantially parallel to the ground surface, And the soil deep part are separated, the ground side becomes a mass of soil, and the front slope of the plowing blade that follows behind promotes the movement, and the direction of movement is regulated upward and guided, and The soil mass that has been forcibly subjected to the moving action is disconnected from the outer soil of the tilling pillar by the subsequent tilling pillar, so that the formed soil mass completely separated by this is located behind the mounting position with the tilling pillar. Forward tilt of the plowing blade It is urged by the structure and exhibits a lifting action toward the surface at once.

The above is also the operation of the present invention, and this state is similar to the operation in the conventional tilling blade.

In the present invention, as described above, the moving body formed by forming the soil mass by the plowing blade and separating it from the adjacent soil by the plowing pillar is a vertical or vertical member connected to the rear end of the plowing blade. In a gap where a pair of separators with a shape similar to the above are held in opposition, the shape is protected and the shape is protected. It is sent to the rear extension line in the longitudinal direction of the tilling blade in the state.

When viewed from the soil side, the moving soil body that receives these actions does not move forward and backward in the locus direction of the plowing blade, but merely moves upward, and is lifted up by the plowing blade and the separating plate. The upper part of the moving mass that has undergone the above-mentioned action and lump maintenance protection is lifted above the surface line of the field, which causes a diffusion phenomenon with the release from the surrounding earth pressure and the disassembly of the lump form and the skin from the crop. Separate action occurs at the same time.

On the other hand, in the ground, the clumps of soil that have passed through the separating plate are lumped due to the frictional action with the immovable soil on the upper part of the upper part, which is not in direct contact with the separating plate, due to the lifting action. The body is destroyed, and the soil attached to the crop acts as a skin separation action, and at the same time, a sand landslide form is formed, and an avalanche phenomenon occurs in the hollowed hollow formed by the lifting, and the soil naturally occurs. The backfill function works.

In combination with the above-mentioned action of the surface of the ground, the harvested material is solidified with the solidified soil around the surface of the harvested material, with the skin separated from or close to the skin, and on the ground or in a crushed state. In the ground near the ground surface, the whole shape is kept healthy and separated from the growing state to make harvesting easier.

Here, regarding the conventional action, the part separated from the soil by the tilling blade becomes a lump and receives the lifting action. Along with this, the lifting soil mass again falls into the cavity formed by lifting.

This may be due to the displacement of the moving weight that is formed at the same time when the cultivating blade is forced to move, or it may be affected by the collapse and the compression at the same time even in the lump formation, and It is considered that there is a part that forms a part that separates the soil from the soil and a part that forms a more solidified state than before.

At the time when such a state is formed, a cavity is formed below it, and due to the passage of the tilling blade, the supporting force disappears, and the earth mass cannot support the load of its own, and When the soil with the thinnest soil is loaded with a mass of soil that exceeds the bearing capacity of the crop in the part where the skin has separated, the cavities are most often embedded in the state of cutting the crop.

This is to apply a compressing action to a desired place to be lifted by separating and separating the soil in the field and the surrounding soil including the harvested object by the plowing blade and the lifting action, and It is believed that these migration effects form a non-uniform soil mass. In other words, it is considered that the plowing blade alone is insufficient for the formation of changes in the soil morphology, which is the overall uplift of the expected effect.

In addition, in the digging machine connected integrally with the tractor of the traction motor vehicle, the steering characteristics of the tractor indicate that the rear wheels are in the direction opposite to the steered wheels with respect to the steering direction of the front wheels. Due to the action of causing the skid phenomenon, the digging machine behind the rear wheel becomes much larger than the skid phenomenon of the rear wheel, and the pair of piers formed with a small gap size causes the skid to slip unintentionally. Depending on the phenomenon, one of the left and right cultivated columns will contact the crop before digging and prevent damage from occurring in the soil. A steering disc is provided on the frame of the vehicle and the steering disc is steered in the same direction as the towing vehicle to resist the side slippage phenomenon of the rear wheels of the towing vehicle and prevent unnecessary action. It is a thing.

For these operations, the harvesting worker who follows the traveling excavator operates the steering handle protruding rearward from the excavator, and adjusts the condition in accordance with the situation of the rear wheels of the towing vehicle. The steering is performed and the steering state is fixed.

The fixing means is provided with a tip of a link that moves back and forth in parallel with the steering handle by a lever provided at a position near the steering handle on an operation panel provided in a part of the steering frame. The lock operation is performed by inserting it into one of the left, right, and neutral locking holes, and releasing the lock resists the elasticity of the spring attached to the lever. A pulling action is applied to release it, and unless the release operation is performed, the insertion and fitting state with the set locking hole is continued and the steering state is maintained.

Next, referring to the drawings, an embodiment of the present invention will be described. A cultivating pillar 5 having a mounting member 3 at a rear portion of a frame 1 provided with a hitch connecting member 2 at a front end thereof and a cultivating blade 4 at a lower end thereof. In a cultivating device for mounting the upper part of a sill, a supporting rod having a tip end, a rear end of a cultivating blade 4 to be mounted on a cultivating column 5 slantingly downward, and a separating plate 6 formed of a vertically or nearly vertically faced body is attached. 7 is arranged so as to be on the extension line of the rear side of the cultivating blade 4 at its tip position, and is detachable from the cultivating blade 4 with a connecting member 8 composed of bolts, nuts and the like.

A steering frame 9 is provided in the middle of the frame 1 in which a hitch connecting member 2 is provided at the front end and a cultivating blade 5 having a separating plate 6 at the rear end is provided via a mounting member 3. A steering member 11 rotatably mounted and rotatably mounted on a steering disk 10 is pivotally supported by the steering itself, and a rear end of a steering handle 12 is directed rearward from a part of the steering member 11. It is installed in such a way that

The steering direction applied to the steering disc 10 can be fixed and released by the fixing means 13.

In the fixing means 13, a link 13 b rotatably supported is connected to one end of a lever 13 a pivotally attached to the rear end of the steering handle 12, and a bracket provided on the steering handle 12 In addition to freely supporting the forward and backward movement, a part of the link 13b and the steering handle 12 are connected by a subring 13c so that the link 13b is always provided with a pulling action in a direction opposite to the mounting position of the lever 13a. It is something to keep.

The operation panel 13d to which the link 13b corresponds is formed at a position where the tip of the link 13b can be brought into and out of contact as a part of the steering frame 9, and the left, right, and The three neutral locking holes 13e are formed by row recesses or through holes.

[0032]

[Effect of the invention]

 As described above, the present invention has a characteristic of a trailer skid phenomenon that occurs during steering in a mining machine for long-rooted crops, in which a towing vehicle that directly connects and pulls the mining machine causes the skid phenomenon of rear wheels. By steering the provided steering disc, it is possible to provide resistance against the occurrence of the rear wheel skid phenomenon, and prevent the cultivated pillars in the position parallel to the crop from eccentric running against the crop. This has the effect of preventing damage due to contact with crops.

In addition, the soil containing the harvested material is raised above the field cultivated ground by the separating plates provided at the rear ends of the pair of forward tilting tilling blades while maintaining the forward tilt angle, and The soil was attached to the soil to prevent it from coming into contact with the surrounding immovable soil at the time of emergence, thereby facilitating hand harvesting, and was also crushed when it rose to the surface of the earth. The hollow part formed by excavating a part of soil can be naturally backfilled to prevent the fall of the crop including the excavated soil and prevent damage to the crop. It has the effect of reducing the amount as much as possible and expecting a healthy harvest.
