Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a plant extracting device, and mainly relates to an apparatus for extracting tap-rooted weeds mixed with grass in a pasture.

[Conventional technology]

Generally, in pastures, taproot weeds that are poor feed sources often grow along with the grass.

This tap-rooted weed is so-called zui, and it has burdock-like roots and not only large and lush leaves, but also roots that have excellent resuscitation ability and reproductive ability. Therefore, this type of weed inhibits the growth of grass, and
If this is mixed with pasture and harvested, the quality of the pasture will deteriorate.

Conventionally, weeds of this type are removed, but in this case, the area around the weeds is dug up relatively widely and deeply, and all of the roots are removed.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional extraction means, there is a problem that the area around the weeds is crushed by the soil that has been dug up over a predetermined area, and the extraction process requires a lot of labor and has poor workability. There's a problem.

Incidentally, as described in Japanese Utility Model Publication No. 38-16602, there is a known lawn care machine equipped with a drilling rod that cuts the roots of the lawn and exposes the soil to the outside air. Since the drilling rod simply moves up and down at a fixed position on a line along the direction of movement of the lawn care machine, it is necessary to move the hole punching rod to a position that is off the line along the direction of movement to perform hole drilling work. I can't do it,
Therefore, when a hole punching rod with this structure is used for pulling out weeds, it is possible to move the hole punching rod directly above the weeds to match the position of the weeds that grow irregularly in the pasture. In many cases, even weeds that grow in the direction of travel cannot be pulled out, making it difficult to use for weed extraction.

Therefore, the present invention was made in view of the above points, and it is possible to easily position the extraction blade directly above the weeds, and to remove the weeds in an orderly and efficient manner without crushing much of the grass surrounding the weeds. The object of the present invention is to provide a plant extracting device that can reliably extract all of the plants.

[Means for solving problems]

The plant extraction device of the present invention includes a frame, a cylinder device that is provided on the frame so as to be freely changeable in position in the front-rear direction and left-right direction, and has a piston rod that is extendable and retractable downward, and a cylinder device that is fixed to the lower end of the piston rod of the cylinder device. The apparatus includes a hollow cylindrical extraction blade body having a digging blade at the lower opening edge and a discharge port at the upper opening, and a handle provided on the cylinder device.

[Effect]

In the plant extraction device of the present invention, the connecting portion of the frame is connected to, for example, a suspension mechanism of a tractor, and the frame is supported by the suspension mechanism of the tractor.

Next, the tractor is driven in the meadow and stopped at the position of the weeds. Then, the position of the cylinder device is changed in the front-rear direction or the left-right direction using the handle, and the excavation blade at the lower opening edge of the extraction blade fixed to the piston rod of the cylinder device is positioned directly above the weeds.

Next, when the cylinder device is actuated to extend the piston rod, the extraction blade body is lowered toward the weeds, and the excavation blade is thrust around the weeds, and the excavation blade is inserted into the soil to a predetermined extraction depth. The weeds are inserted deeply and are trapped inside the extraction blade body at the upper part of the excavation blade.

Also, when the cylinder device is activated to contract the piston rod, the piston rod pulls the extraction blade upward from the soil, and the extraction blade is lifted up while holding the weeds, and the weeds are removed from the surrounding grass. It can be removed without damage or contamination.

Then, the weeds are successively pulled out by the extraction blade and the weeds are held in the extraction blade,
Each weed in the extraction blade body is successively pushed up above the extraction blade body by the weeds in the lower part, and sequentially discharged outward from the discharge port at the upper end opening of the extraction blade body.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a frame, and this frame 1
Connecting portions 2 and 3 for connecting the lower ring B and top link C on both sides of the tractor A are provided at the lower and upper portions of both sides, respectively. Furthermore, a connecting frame 4 is integrally protruded rearward from both rear sides of the frame 1, and a seat 5 is attached between the rear ends of the connecting frames 4 on both sides. A footrest frame 5a integrally projects downward.

Next, a vertical shaft 6 is integrally attached to approximately the middle part of the frame 1 by support arms on both sides, and a movable arm 8 shown in FIG.
One end of the first movable arm 8 is rotatably attached in the horizontal direction, and an interlocking vertical shaft 10 is rotatably attached to the other end of the first movable arm 8 via a bearing body 9. Further, one end of a second movable arm 12 is rotatably attached to the interlocking vertical shaft 10 via a bearing body 11, and a mounting frame 13 is attached to the other end of the second movable arm 12. The upper and lower parts of a hydraulic cylinder 16 as a cylinder device are respectively mounted between upper and lower mounting plates 14 and 15 which are fixed together and protrude integrally from the upper and lower ends of this mounting frame 13. has been done.

The hydraulic cylinder 16 supported by the mounting frame 13 is moved in the front-rear direction and the left-right direction via the first movable arm 8 and the second movable arm 12 around the vertical axis 6 and the interlocking vertical axis 10. It is installed so that its position can be changed freely.

A downwardly telescopic piston rod 17 of the hydraulic cylinder 16 is attached to the lower mounting plate 1.
The upper end of the extraction blade 19 is connected to the lower end of the piston rod 17 which protrudes downward from the guide hole 18 through a horizontal connecting piece 20. It is suspended in one piece.

The extraction blade body 19 is formed into a hollow cylindrical shape that opens in the vertical direction, and has a holding guide hole 21 formed therein for holding weeds and guiding the weeds upward. A tapered digging blade 22 is formed at the lower opening edge of the holding guide hole 21, and a discharge port 23 for discharging weeds outward is formed at the upper opening of the holding guide hole 21.

Further, on both sides of the mounting frame 13, operating handles 24 for changing the position of the hydraulic cylinder 16 in the front-rear direction and left-right direction are curved toward the rear side. A grip portion 25 is attached to the holder. Furthermore, piston rods 1 are provided at the upper and lower portions of the hydraulic cylinder 16.
One end of the oil feed pipes 26, 27 for moving the oil up and down is opened for communication, and the other end of the oil feed pipes 26, 27 is connected to the hydraulic drive mechanism of the tractor A via a changeover switch 29 having a changeover lever 28. They are now linked together.

Next, the operation of the above embodiment will be explained.

Lower ring B and top link C of tractor A
The connecting portions 2 and 3 of the frame 1 are connected to each other. Further, oil feed pipes 26 and 27 connected to the hydraulic cylinder 16 are connected to the hydraulic drive mechanism of the tractor A via a changeover switch 29.

Next, the tractor A travels in the pasture, and stops at the position of the weed a.

Then, the operator M seated on the seat 5 operates the operating handle 24 as necessary, and uses the operating handle 24 to move the hydraulic cylinder 16 supported by the mounting frame 13 in the front-back or left-right direction. The digging blade 22 at the lower end of the extraction blade body 19 attached to the piston rod 17 is positioned directly above the weed a to be extracted. In this case, the hydraulic cylinder 16
is supported so as to be horizontally rotatable in the longitudinal and lateral directions via first and second movable arms 8 and 12 that are mutually rotatable about the vertical axis 6 and an interlocking vertical axis 10. The setting position of the extractor blade 19 can be easily selected.

Next, by operating the hydraulic drive mechanism of tractor A and switching the changeover switch 29, the hydraulic cylinder 16 is activated to extend the piston rod 17, and the extracting blade body 19 is lowered, and the extraction blade 19 is lowered from the excavation blade 22 at the lower opening edge. It pokes around weed a,
The weed a is inserted deep into the soil to a predetermined extraction depth along the tap root part b of the weed a, and the weed a whose circumference has been cut by the excavation blade 22 is inserted into the holding guide hole 21 of the extraction blade body 19. being held.

Next, when the changeover switch 29 is operated,
The elongated piston rod 17 is contracted and the extraction blade 19 is raised while holding the weeds a, and the weeds a are extracted without damaging or staining the surrounding grass.

In addition, the tractor A is driven and moved to another weed spot, and the hydraulic cylinder 16 is operated again to extend the piston rod 17, and the extraction blade 19 is lowered to move it to another weed spot. When the weed a is inserted in the same manner as above, the weed a is similarly extracted and held in the holding guide hole 21 of the extraction blade 19, and the second weed a holds the first weed a that was held earlier. Weeds a are pushed up through the holding guide hole 21.

In this way, the weeds a are sequentially pulled out and held in the holding guide hole 21 by the vertical movement of the extraction blade 19, and the weeds a in the lower part are removed from the weeds in the upper part in the holding guide hole 21. The weeds a are successively pushed up, and finally the weeds a are successively pushed out of the extraction blade body 19 from the discharge port 23 of the holding guide hole 21 and are discharged.

In the above case, the weed a is removed along with the soil around the tap root part b through the holding guide hole 21 of the extraction blade body 19.
In other words, the soil containing the tap root part b is extracted in a state that is solidified in the shape of the inner diameter of the holding guide hole 21, so that the weed a is pushed up and discharged from the holding guide hole 21. When the weeds are discharged from the discharge port 23, the soil around the tap root part b acts as a lubricant, so that the weeds a are smoothly pushed up from below and are discharged from the discharge port 23. It is something that will be done.
