The vehicle is towed to remove grass from the field.

Japanese Patent Application Publication No. 2007-282595

The weeding machine (agricultural machine) disclosed in Patent Document 1 can raise and lower the tool bar to which the weeding tool is attached between the raised position and the lowered position. Grass can be removed by penetrating to a predetermined depth. However, in fields such as fields and vegetable gardens that are targeted for weeding, there are variations in hardness, weight, stickiness, etc. due to differences in soil quality, and even with the same soil quality, soil conditions change daily due to the influence of weather, temperature, etc. Even if the height of the tool bar is adjusted so that the tip of the weeding tool penetrates the ground to a predetermined depth, weeds may not be effectively removed.

The present invention has been made in view of the actual state of the prior art, and its first purpose is to provide an agricultural machine that can effectively perform tasks such as weeding in accordance with soil conditions.

In the working device for agricultural machinery configured in this way, the elastic connecting plate bends in the direction of the plate surface depending on the soil conditions such as the hardness and soil quality of the soil to be worked on, so the work can be performed in the direction of the plate surface of the elastic connecting plate. Work such as weeding can be performed while the tool is elastic.

In the working device for agricultural machinery having the above configuration, if the length of the cantilever beam whose free end is the fixed position of the working tool is adjustable, the length of the elastic connecting plate can be adjusted depending on the hardness, soil quality, etc. of the soil to be worked. Since the degree of deflection (tension) of the elastic connecting plate can be freely changed according to the soil conditions, work such as weeding can be performed effectively according to the soil conditions. Moreover, since the work tool is attached to the support member via an elastic connection plate, even if a work tool with high rigidity is used, it is not possible to perform work such as weeding while the work tool is elastic. can.

In addition, if the working device for agricultural machinery having the above configuration is provided with an elevating mechanism that moves the supporting member up and down in the vertical direction, it is necessary to set the length of the cantilever of the elastic connecting plate appropriately and then It is possible to adjust the amount of plunge of the work implement attached to the board into the ground.

In order to achieve the above-mentioned second object, the agricultural machine of the present invention includes a support member attached to a traveling machine body, a holder that can be fixed to the support member, and a machine that is supported in a cantilever shape by the holder. The present invention is characterized in that it includes an elastic connecting plate having an elastic connection plate, and a working tool attached to a free end side of the elastic connecting plate, and the elastic connecting plate is an elongated plate material that bends in the direction of the plate surface.

A connecting plate 8, working tools 9 and 10 fixed to the free end of the first elastic connecting plate 8, and a second elastic connection extending vertically downward in a cantilever shape with the second support shaft 7 as a fixed end. It comprises a plate 11 and a working tool 12 fixed to the free end of the second elastic connecting plate 11. Hereinafter, the traveling direction of the traveling body 4 will be described as a front-rear direction, and the direction orthogonal to the front-rear direction will be referred to as a left-right direction.

The traveling body 4 includes an engine cover 13 that houses an engine (not shown) mounted on the rear side of the body frame 5, and an operation knob 14 that can be grasped by an operator. It is configured so that it can move forward and backward using the driving force. However, the engine may be omitted and the vehicle may be driven manually.

The first support shaft 6 and the second support shaft 7 are constituted by square pipes, and both support shafts 6 and 7 extend horizontally in the left-right direction of the traveling body 4. Screw members 15 are connected to both ends of the first support shaft 6, and these screw members 15 are screwed into the fuselage frame 5. By rotating an adjustment lever 16 attached to the upper end of the screw member 15, the first support shaft 6 is moved up and down in the vertical direction, thereby making it possible to adjust the mounting height with respect to the body frame 5.

A plurality of holding bodies 17 having a rectangular cylinder shape are inserted and held in the first support shaft 6 so as to be movable along the axial direction, and these holding bodies 17 are fixed to the first support shaft 6 using fixing means such as bolt tightening. The support shaft 6 is fixed at any position on the support shaft 6. A first elastic connecting plate 8 is held and fixed to each holding body 17, and the details will be described later, but by changing the fixing position of the first elastic connecting plate 8 to the holding body 17, the first elastic connecting plate 8 can be held and fixed. The length of the cantilever of the elastic connecting plate 8 can be adjusted.

The second support shaft 7 is disposed on the fuselage frame 5 at a position forward of the first support shaft 6, and although not shown, the same lifting mechanism as the first support shaft 6 is applied. Accordingly, the mounting height of the second support shaft 7 with respect to the fuselage frame 5 can also be adjusted. However, the second support shaft 7 may be fixed to the body frame 5, and the mounting height of the second support shaft 7 to the body frame 5 may not be adjustable.

A plurality of holding bodies 18 having a rectangular cylinder shape are inserted and held in the second support shaft 7 so as to be movable along the axial direction, and these holding bodies 18 are fixed to the second support shaft 7 using fixing means such as bolt tightening. The support shaft 7 is fixed at an arbitrary position. A second elastic connecting plate 11 is held and fixed to each holding body 18, and the details will be described later, but by changing the fixing position of the second elastic connecting plate 11 with respect to the holding body 18, the second elastic connecting plate 11 is held and fixed. The length of the cantilever of the elastic connecting plate 11 can be adjusted.

The first elastic connection plate 8 is made of a highly flexible long plate material such as metal such as stainless steel or fiber reinforced plastic (FRP), and as shown in FIGS. The plate 8 is inserted into a through hole provided on the front side of the holder 17 so as to be movable up and down, and is fixed to the holder 17 using bolts 19 . Two types of working tools 9 and 10 are fixed to the lower end side of the first elastic connecting plate 8 using bolts 20, with their positions shifted in the front-rear direction. These work tools 9 and 10 are weeding tools for removing grass in the field, and weeding tools of various shapes are selectively used depending on the situation of the field to be worked on, the type of crops planted, etc. It is now in use. In the weeding machine 1 according to this embodiment, two types of work tools 9 and 10 are used to continuously remove grass in the field in the front and back direction, but the rear work tool 10 is omitted. , only the front working tool 9 may be fixed to the lower end side of the first elastic connecting plate 8.

The first elastic connecting plate 8 is pressed and fixed to the holding body 17 by the fastening force of the bolt 19, and the length of the cantilever from the fixed end to the free end of the first elastic connecting plate 8 is can be changed freely. For example, as shown in FIG. 5(a), when the upper side of the first elastic connecting plate 8 is fixed to the holder 17 with bolts 19, the length of the cantilever beam of the first elastic connecting plate 8 is However, as shown in FIG. 5(b), when the lower side of the first elastic connecting plate 8 is fixed to the holder 17 with bolts 19, the cantilever of the first elastic connecting plate 8 The length of the beam is L2, which is shorter than L1. In this way, depending on the fixed position of the first elastic coupling plate 8 with respect to the holding body 17, the first elastic coupling plate 8 is moved from the fixed end (bolt 19) to the free end (bolt 20 for fixing the working tools 9, 10). Since the length of the first elastic connecting plate 8 is changed, it is possible to set the degree of deflection (tension) of the first elastic connecting plate 8 suitable for the soil conditions such as the hardness and soil quality of the soil to be worked on. Note that if it is desired to further increase the degree of flexure (tension) of the elastic connecting plates 8, a plurality of elastic connecting plates 8 may be used in a stacked manner.

In addition, an indicator 8a such as a scale or a position mark is provided on the surface of the first elastic connecting plate 8, and the length of the cantilever beam of the first elastic connecting plate 8 can be adjusted using this indicator 8a as a guide. I have to. Therefore, even if a plurality of first elastic connecting plates 8 are attached to the first support shaft 6 via the holder 17, the operator must check the length of the cantilever of all the first elastic connecting plates 8. can be easily and accurately adjusted to be the same.

The second elastic connecting plate 11 is made of a highly flexible elongated plate material such as metal such as stainless steel or fiber reinforced plastic, and as shown in FIG. It is inserted into a through hole provided on the front side of 18 so as to be able to move up and down, and is fixed to holder 18 using bolts 21 . A working tool 12 is fixed to the lower end side of the second elastic connecting plate 11 using bolts 22 . This work tool 12 is a weeding tool that has a different shape from the work tools 9 and 10 attached to the first elastic connecting plate 8. A capable grooving tool is used as the working tool 12.

The second elastic connecting plate 11 is supported in a cantilevered manner on the second support shaft 7 with a fixed end fixed to the holder 18 using a bolt 21, and a bolt 22 is attached to the free end of the second elastic connecting plate 11. The work tool 12 is attached using the same. The length of the cantilever from the fixed end to the free end of the second elastic connecting plate 11 can be changed, but the adjustment mechanism for changing the length of the cantilever is different from that of the first elastic connecting plate 8. Since they are similar, repeated explanation will be omitted here.

Next, weed removal work using the weeding machine 1 configured as described above will be explained.

First, the work tools 9 and 10 attached to the first elastic connecting plate 8 and the second elastic connecting plate are checked by checking the row spacing of crops planted in the field (field) to be worked on, the growth of weeds, etc. After selecting the work tool 12 to be attached to the first elastic connecting plate 8 and the second elastic connecting plate 11, the first elastic connecting plate 8 and the second elastic connecting plate 11 are connected by taking into account the soil conditions in the field, such as the hardness, soil quality, dryness, etc. Adjust the length appropriately.

Here, if the soil in the field is clayey and contains some moisture, the length of the cantilever of the first elastic connecting plate 8 is relatively long L1, as shown in FIG. 5(a). The upper side of the first elastic connecting plate 8 is fixed to the holder 17 with bolts 19 so that On the other hand, if the soil in the field is sandy and dry, the length of the cantilever of the first elastic connecting plate 8 is shorter L2, as shown in FIG. The lower side of the first elastic connecting plate 8 is fixed to the holder 17 with bolts 19. If the soil conditions in the field are other than the above, adjust the attachment position of the first elastic connecting plate 8 to the holder 17 so that the length of the cantilever beam is optimal. It is fixed to the holding body 17 with bolts 19.

In addition, the mounting position of the holder 17 in the axial direction of the first support shaft 6 is changed so as to be able to weed between the rows of crops and between the furrows that serve as the travel path for the traveling machine 4. The horizontal spacing P of the first elastic connecting plate 8 is adjusted. Further, the adjustment lever 16 is rotated to move the first support shaft 6 up and down in the vertical direction so that the height positions of the working tools 9 and 10 with respect to the ground of the field are appropriate. Adjust the mounting height of the first support shaft 6. For example, when attempting to move soil during weeding during weeding, the mounting height of the first support shaft 6 relative to the machine frame 5 may be adjusted in consideration of the amount of protrusion of the work tool 9 relative to the ground and the angle of entry. .

Similarly, regarding the second elastic connecting plate 11, by changing the fixing position of the second elastic connecting plate 11 with respect to the holder 18, the second elastic connecting plate 11 can be fixed in consideration of the hardness of the soil in the field. Adjust the length of cantilever beam 11 appropriately. In addition, the mounting position of the holder 18 in the axial direction of the second support shaft 7 is changed to enable weeding between the rows of crops and between the furrows that serve as the travel path for the traveling machine 4. The distance between the two elastic connecting plates 11 in the left and right direction is adjusted.

By moving the traveling body 4 forward in the right direction in FIG. 1 in this state, the working tool 12 attached to the second elastic connecting plate 11 on the front row side in the traveling direction and the first elastic By towing the work implements 9 and 10 attached to the connecting plate 8, the field can be weeded. At that time, since the first elastic connecting plate 8 and the second elastic connecting plate 11 are given tension suitable for the soil conditions (soil hardness, soil quality, etc.) to be worked on, the working tools 11 on the front row side After cutting a deep groove in the ground in the area to be weeded and loosening the soil, the soil was then moved to lift the grass using implement 9 placed on the row side, and then lifted using implement 10 on the last row. You can rake the grass.

As explained above, the weeding machine (agricultural machine) 1 according to the present embodiment includes the first support shaft 6 and the second support shaft 7 attached to the body frame 5 of the traveling body 4, A first elastic connecting plate 8 and a second elastic connecting plate 11 supported in a cantilevered manner by the first supporting shaft 6 and the second supporting shaft 7, and the first elastic connecting plate 8 and the second elastic connecting plate 11 are working tools 9, 10, 12 attached to the free ends of the elastic coupling plates 11, the first elastic coupling plates 8 and the second elastic coupling plates 11 are connected to the first support shaft 6 and the second support shaft, respectively. The mounting position in the left and right direction with respect to the support shaft 7 can be adjusted, and the length of the cantilever beam from the fixed end to the free end can be adjusted, so it is possible to adjust the length of the cantilever beam from the fixed end to the free end. The degree of deflection (tension) of the elastic connecting plates 8, 11 can be freely changed according to the soil conditions, and work such as weeding can be performed effectively according to the soil conditions. Furthermore, since the working tools 9, 10, 12 are attached to the support shafts 6, 7 via the elastic connecting plates 8, 11, even if a highly rigid working tool is used, the working tool must have elasticity. Work such as weeding can be carried out in this state.

In addition, holding bodies 17 and 18 that hold the first and second elastic connecting plates 8 and 11 in a movable manner are movably supported on the first and second support shafts 6 and 7, respectively. Since the bodies 17, 18 are fixed at predetermined positions on the corresponding support shafts 6, 7, the fixing positions of the holding bodies 17, 18 with respect to the first and second support shafts 6, 7 cannot be changed. Therefore, the distance between the working tools 9, 10, and 12 in the left-right direction can be easily adjusted according to the working position in the field. Therefore, even if the row spacing is narrow, the working tools 9, 10, 12 can be placed in positions that do not interfere with the crops, and the working tools 9, 10, 12 can be placed between the rows without damaging the crops. Weeding work can be performed effectively.

In addition, since the first and second elastic connecting plates 8 and 11 are provided with an index indicating the length of the cantilever beam, by visually observing this index, the first and second elastic connecting plates 8 and 11 are , 11 can be easily and reliably adjusted. Moreover, since the first and second elastic connecting plates 8, 11 are inserted into the through holes of the corresponding holders 17, 18, and their vertical positions are adjusted, they are fixed with the bolts 19, 21. The fixed position of the elastic connecting plates 8, 11 relative to the bodies 17, 18 can be changed steplessly. Furthermore, since the first and second elastic connecting plates 8 and 11 made of elongated plate materials can be bent only in the direction of the plate surface, and not in the left and right direction perpendicular to the plate surface, the elastic connecting plates Lateral wobbling of the working tools 9, 10, 12 fixed to the parts 8, 11 can be prevented.

In addition, in the weeding work machine 1 according to the present embodiment, the traveling machine body 4 is provided with a lifting mechanism (screw member 15 and adjustment lever 16) that moves the first support shaft 6 up and down in the vertical direction. The length of the cantilever beam of the first elastic connecting plate 8 supported by the first supporting shaft 6 is set appropriately, and the working tools 9 and 10 are attached to the free end of the first elastic connecting plate 8. The amount of plunge into the ground can be adjusted. Note that as the lifting mechanism for moving the first support shaft 6 up and down in the vertical direction, an electric device using a motor or the like as a drive source is used, so that the vertical movement of the first support shaft 6 is performed electrically. It's okay.

In addition, in the weeding work machine 1 according to the present embodiment, the first support shaft 6 that supports the first elastic connection plate 8 and the second support shaft 7 that supports the second elastic connection plate 11 travel. Work tools (weeding tools) 9, 10, 12 having different shapes are arranged in two rows along the longitudinal direction of the machine body 4, and at the free ends of these first and second elastic connecting plates 8, 11. For example, after cutting a deep groove in the ground at a place to be weeded with the work tool 12 on the front row side in the traveling direction, the work tools 9 and 10 placed on the rear row can cut the weeds. You can move the soil so that it floats, and scrape up the grass that has risen to the surface.

Note that the above-described embodiments are merely examples for explaining the present invention, and various other modifications may be adopted. For example, in the above embodiment, a case has been described in which the fixing position of the first elastic connecting plate 8 with respect to the holder 17 can be changed steplessly, but as shown in FIG. A plurality of mounting holes 8b are provided at predetermined intervals in the vertical direction, and by selectively inserting bolts 19 into these mounting holes 8b, the fixed end of the first elastic connecting plate 8 can be separated from the free end. It may also be possible to change the length of the cantilever leading to .

That is, as shown in FIG. 7(a), when the first elastic connecting plate 8 is fixed to the holder 17 by inserting the bolt 19 into the upper mounting hole 8b, the cantilever beam of the first elastic connecting plate 8 However, as shown in FIG. 7(b), if the bolt 19 is inserted into the lower mounting hole 8b and the first elastic connecting plate 8 is fixed to the holder 17, The length of the cantilever of the first elastic connecting plate 8 is shorter L2. In this way, depending on the formation position of the mounting hole 8b into which the bolt 19 is inserted, the first elastic connecting plate 8 is connected from the fixed end (the bolt 19) to the free end (the bolt 20 for fixing the working tools 9 and 10). Since the length is changed, it is possible to set the degree of deflection (tension) of the first elastic connecting plate 8 suitable for the soil conditions to be worked on. In this case, the plurality of mounting holes 8b not only function as connecting parts between the bolts 19 and the first elastic connecting plate 8, but also function as indicators indicating the length of the cantilever beam of the first elastic connecting plate 8. are doing.

Furthermore, in the embodiment described above, the first elastic connection plate 8 and the second elastic connection plate 11 are arranged in two rows along the front-rear direction of the traveling body 4, but the second elastic connection plate The plate 11 may be omitted to provide a single-row structure with only the first elastic connecting plate 8, or a structure may be adopted in which three or more rows of elastic connecting plates are arranged in the front-rear direction.

In addition, in the above embodiment, when adjusting the length of the cantilever from the fixed end to the free end of the first and second elastic connecting plates 8, 11, the fixed end can be adjusted without changing the position of the free end. However, on the contrary, it is also possible to change the position of the free end without changing the position of the fixed end, or to change the position of both the fixed end and the free end. You can do it like this.

Further, in the above embodiment, the weeding machine 1 using weeding tools as the working tools 9, 10, 12 has been described, but the types and shapes of the working tools are not limited to the above embodiments. It is also possible to use tools for surface mixing, drawing, seeding, etc.
