Description

  The present invention holds a seedling roll in which a long mat seedling is formed in a roll shape so that the seedling roll can be fed onto a seedling stand by a roll holder, and the long mat seedling is sequentially moved to a planting opening by moving the seedling stand laterally. It is related with the seedling roll loading type seedling transplanting machine which carries out transplanting.

  The seedling transplanting machine described in Patent Document 1 holds a seedling roll in which a long mat seedling that is long and continuous with a predetermined width is formed in a roll shape so that it can be fed onto a seedling mounting table by a roll holder. While moving the long mat seedling up to the position where it reaches the seedling receiving plate on which the opening for planting has been formed, the lateral movement of the long mat seedling extends over the width of the long mat seedling. Since the planting tools are sequentially stocked and planted in the field with respect to the entire width, a long-running transplantation can be continuously performed with a single long mat seedling by repeating the reciprocating lateral movement of the seedling platform.

However, since the long mat seedling of the seedling roll is formed by a long belt-like base material that can be easily deformed by a nonwoven fabric or the like, the seedling roll is swung from side to side during the folding operation of the reciprocating lateral movement of the seedling platform. The width dimension is reduced due to the compressive action on both side edges, and the long mat seedling of the seedling roll by hydroponic cultivation is rubbed against the seedling receiving plate during the lateral movement of the seedling platform, and the seedling by the planting tool The removal of the long mat seedling by taking out the surrounding seedlings to the outlet reduces the width of the long mat seedling. It may cause a situation to occur.

  The problem to be solved is that the long mat seedling of the seedling roll can be transplanted and run without any stock loss by suppressing the reduction of the width dimension when the seedling stage is swung to the left and right by the reciprocating lateral movement of the seedling platform. An object of the present invention is to provide a seedling roll-loading type seedling transplanter.

  The invention according to claim 1 includes a roll holder (10) for holding a seedling roll (R) in which a long mat seedling (M) that is long and continuous in a predetermined width dimension is formed in a roll shape, and the long mat seedling. The long mat seedling (M) is moved by reciprocating lateral movement within the range of its width while feeding (M) to the position where it reaches the seedling receiving plate (14) in which the opening for planting is formed by the attached seedling feeding means. In a seedling roll-loading type seedling transplanting machine that has a seedling stage (11) that sequentially moves the tip to the opening, and transplants long mat seedlings (M) in stock, the seedling stage (11) is fed out. A mat seedling width maintaining means for maintaining the width of the long mat seedling (M) is provided.

  The seedling roll is held in a roll holder so that it can be fed out, and the long mat seedling is fed to a position where it reaches the seedling receiving plate on which a planting opening has been formed by the seedling mounting stand, and the original of the long mat seedling. The long mat seedlings are transferred by dividing the tip of the long mat seedling to the above-mentioned outlet by reciprocating lateral movement within the range of the width dimension, and the width dimension is maintained by the mat seedling width maintaining means at this time. .

According to a second aspect of the present invention, in the configuration of the first aspect, the seedling width maintaining means sets the center position of the width of the long mat seedling (M) immediately before the seedling receiving plate (14) on the seedling mounting base (11). It is characterized by being formed by a guide support material (16a) that is supported higher than the bottom plate (11b).
Since the long mat seedling is supported by the guide support material so as to be slidable at the center of the width, the long mat seedling is sent to the seedling receiving plate while being extended to both outer sides.

According to a third aspect of the present invention, in the configuration of the first aspect, the seedling width maintaining means sets the center position of the long mat seedling (M) at the position immediately before the seedling receiving plate (14) of the seedling mounting base (11). A rotating body (21) is provided, which is rotatable so as to partially protrude from the bottom plate (11b) of the seedling stage (11) so as to be lifted higher than the bottom plate (11b).

Protrusions (24a, 24a) that contact the left and right outer portions of the seedling (M) and act in the outer direction by the transfer operation are formed.
By the left and right seedling feeding belts on which the protrusions are formed, the long mat seedling is subjected to the action in the outer direction while the left and right outer portions are transferred by the protrusions on the belt surface.

The invention according to claim 6 is characterized in that, in the configuration of claim 1, the seedling width maintaining means is provided with a seedling presser (25) for pressing the long mat seedling (M) on the lower side of the transfer toward the outer side. To do.
By the seedling presser, the long mat seedling first comes into contact with the center position of the width of the seedling presser and is moved so that the holding position moves to the outer side as it is transferred and is spread from the center of the width of the long mat seedling to the left and right outer sides. .

  According to the structure of claim 1, the seedling roll-loading type seedling transplanting machine is configured so that the matting width maintaining means suppresses the shrinkage of the long mat seedling in the width direction so that the original width dimension is maintained and the planting opening for planting is maintained. Since reaching the formed seedling receiving plate, the entire width of the long mat seedling is moved in a range extending over the original width dimension, so that the entire width can be sequentially divided, and a long-distance transplanting run can be performed without causing a shortage.

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
The side view of the seedling transplanter which is one Example of this invention is shown in FIG.
This seedling transplanter 1 includes a steering post 4 for steering an aircraft having a steering handle 4a, etc., for a vehicle that is supported and driven by left and right steering wheels 2 and 2 and left and right rear wheels 3 and 3 so that four wheels can be driven. A driver's seat 4b facing the steering post 4 is arranged, and an engine 5 for supplying power to each part of the seedling transplanter is mounted below the driver's seat 4b. Steps are provided at the base of the steering post 4 and the driver's seat 4b. A floor 6 is provided, and the rear end portion also serves as a fender cover for the rear wheel 3. Further, a planting part 7 for planting and traveling the long mat seedling in conjunction with the traveling of the body by mounting the seedling roll R is provided at the rear part of the body so as to be able to move up and down via the parallel link mechanism 7a. In the present specification, the left direction and the right direction of the seedling transplanter 1 are referred to as the left side and the right side, respectively.

  As shown in FIG. 2, an enlarged side view of the planting portion 7 is configured around a transmission case 7b that receives power from the engine 5, and a winding core C of a seedling roll R in which a long mat seedling is formed in a roll shape. A seedling mount 11 having a roll holder 10 that holds the long mat seedlings from both outer sides and guides and transfers the long mat seedlings, and a number of seedlings along a predetermined circular trajectory T. It consists of a planting device 12 that is taken and planted in the soil, a float 13 that levels the seedling planting surface of the farm field, and the like.

  The seedling roll R is formed in a roll shape by winding a long mat seedling M, which has a width conforming to the guide width of the seedling mount 11 and is longer than the guide length, around the winding core C. The roll holder 10 is configured to hold the long mat seedling M of the seedling roll R on the seedling mounting base 11 so that the long mat seedling M can be fed out and to be detachable from the seedling mounting base 11.

  The seedling stage 11 is provided with seedling feeding means by a seedling feeding belt 15 for transferring the long mat seedling M along an inclined path, and is provided with a mat seedling width maintaining means described later, and the lower end of the long mat seedling M is provided at the lower end. A seedling receiving plate 14 with a mouth is provided, and the long mat seedling M of the seedling roll R is guided to the seedling receiving plate 14. The seedling mounting table 11 is configured to be laterally movable, and is reciprocated in the width direction of the machine body within a range equal to the width dimension of the seedling roll R, so that the planting device 12 is long from the notch opening of the seedling receiving plate 14. The entire width of the mat seedling M is configured so as to be capable of being stocked sequentially.

  The mat seedling width maintaining means is for maintaining the width dimension of the long mat seedling M that is fed to the seedling mount 11 and transferred to the seedling receiving plate 14. FIG. 3 shows a side view of a seedling mounting table in which the specific configuration is applied to the six-row planted seedling mounting table 11, its main part A arrow view, and its main part B arrow view (ac).

  The ramp of the seedling platform 11 includes a bottom plate 11b that slidably supports the long mat seedling M for each strip, and left and right partition portions 11s and 11s that stand on both sides of the strip and guide the mat seedling. Left and right seedling feeding belts 15 and 15 for transferring the long mat seedling M are provided in the vicinity of the seedling receiving plate 14 on the slope.

  The mat seedling width maintaining means is formed by a guide support material 16a that slidably supports the long mat seedling M by an inclined surface formed on both sides of a section that rises in a mountain shape immediately before the seedling receiving plate 14. In order to guide the long mat seedling M smoothly, the entrance side of the guide support member 16a is configured to gradually increase from the bottom plate 11b at the center position of the width as it advances along the slope of the seedling mount 11.

  Thus, by forming the mat seedling width maintaining means by the guide support material 16a, when the long mat seedling M is sent to the seedling receiving plate 14, it opens from the center of the width to the left and right along the inclined surface of the mountain. Since it is extended, the width of the original long mat seedling M is maintained at the position of the seedling receiving plate 14, so that the entire width of the long mat seedling M is sequentially divided by the planting device 12, and planting is performed without causing a missing strain. be able to.

  In this case, instead of the mat seedling width maintaining means 16a, it is possible to adjust the lateral movement amount of the seedling platform to the reduced width of the long mat seedling of the seedling roll by exchanging the parts of the transmission mechanism. In contrast to this, by providing the mat seedling width maintaining means 16a as described above, both types of mat seedlings can be used properly in the field and the seedling transplanting machine can be used flexibly. Operation becomes possible.

(Another configuration example)
Next, a mat seedling width maintaining means having another configuration will be described.
As for the mat seedling width maintaining means, as shown in FIG. 4, a side view of an enlarged main part of the first alternative configuration example of the seedling stage, and A and B arrow views (ac) are shown in FIG. 4. A rotating body 21 that protrudes partly from the bottom plate 11b according to the planting strip so as to lift the center of the long mat seedling M that passes through the slope, and the left and right sides of the long mat seedling M that are transported on both sides of the rotating mat 21 The seedling feeding belts 15 and 15 are provided and configured. A plurality of protrusions 15a are formed on the surfaces of the left and right seedling feeding belts 15 and 15 so as to catch the bottom surface of the long mat seedling M without slipping. The plurality of protrusions 15a. Are arranged in a square shape.

  With the above configuration, when the long mat seedling M descends along the inclined path of the seedling mount 11, the central portion is raised to the height by the lift roller 21 while being caught by the plurality of protrusions 15 a of the left and right seedling feeding belts 15, 15. Since the long mat seedling M is extended to the left and right, the initial mat seedling width is maintained at the position of the seedling receiving plate 14.

  Further, the mat seedling width maintaining means includes a perspective view of a main part, a side view, and a main part A arrow view (ac) as shown in FIG. The left and right lateral feed belts 22, 22 that move laterally so as to pull the long mat seedling M to the left and right are provided below the seedling feed belts 15, 15 and immediately before the seedling receiving plate 14. These left and right lateral feed belts 22 and 22 are configured such that the roller shafts are connected from the left and right seedling feed belts 15 and 15 through a transmission system 22t by a bevel gear or the like so as to be able to perform an interlocking operation.

  With the above configuration, when the long mat seedling M descends along the slope of the seedling mount 11, the long mat seedling M is pulled left and right when crossing the left and right lateral feed belts 22, 22. The original mat seedling width is maintained.

  In addition, the mat seedling width maintaining means, as shown in FIG. 6, is a side view of the third alternative configuration example of the seedling mounting table, as shown in FIG. The left and right seedling feeding belts 23, 23 are arranged in a square shape so that the long mat seedling M is transferred while being expanded.

  With the above-described configuration, when the long mat seedling M descends along the seedling mount 11, it is expanded to the left and right by the transfer force of the left and right seedling feeding belts 23, 23. Maintained.

  Further, the mat seedling width maintaining means, as shown in FIG. 7, shows a side view, a main part A view, and a main part perspective view (ac) of a fourth alternative configuration example of the seedling stage. In the lower part of the stage 11, left and right seedling feeding belts 24, 24 having predetermined protrusions 24a, 24b for transferring the long mat seedling M formed on the surface thereof are arranged in parallel. The protrusions 24a and 24b of the left and right seedling feeding belts 24 and 24 are formed outward so that the protrusions 24a and 24a that are in contact at both outer positions of the long mat seedling M expand the long mat seedling M.

  With the above configuration, when the long mat seedling M descends along the seedling mount 11, it is expanded by the projections 24 a, 24 a on both outer sides of the left and right seedling feeding belts 24, 24. The mat seedling width is maintained.

  In addition, the mat seedling width maintaining means is configured to incline the seedling mounting base 11 as shown in FIG. 8 in a side view and a main portion A arrow view (a, b) of the fifth separate configuration example of the seedling mounting base. In the lower part of the road, a mat seedling width maintaining unit is configured by providing a seedling presser 25 that presses the long mat seedling M toward the lower side of the transfer at the position immediately before the seedling receiving plate 14. The long mat seedling M is first brought into contact with the center of the width of the seedling presser 25 by the seedling presser 25, and the presser position moves to the outer side as it is transferred. The initial mat seedling width is maintained under the action of being spread.

(Installation work assistance)
Next, the structure of the roll holder of the seedling mounting stage related to seedling roll mounting work assistance will be described.
In the planting operation of the seedling transplanter, when a new seedling roll R is mounted on the seedling mount 11, conventionally, the other hand while holding the roll holder 10 with one hand so as to fit the winding center of the seedling roll R. In order to reduce the burden, the temporary support device for the roll holder was provided on the seedling mounting base in order to reduce the burden of mounting the seedling roll R weighing approximately 10 kg. Is.

  Specifically, as a sixth alternative configuration example of the seedling stage, as shown in FIG. 9, a side view of the pre-mounting state and the main part A arrow view (a, b) are shown in FIG. The support shaft 10b of the roll holder 10 is supported so as to be rotatable, a handle 10h is provided for the rotation operation, and the roll holder 10 receives a spring steel hook 31 connected to the seedling table 11. Is provided at a predetermined height.

  When the seedling roll R is mounted, as shown in FIG. 3C, a side view of the state of use is to rotate the roll holder 10 upward by operating the handle 10h, and hook the hook 31 on the arm 10a. Thus, the roll holder 10 is hooked and held so as to float at the mounting height position of the seedling roll R. In this state, the seedling roll R can be easily mounted in the mounting opening 10r of the roll holder 10.

(Seedling feed compensation)
Next, a roll holder moving device for feeding seedlings at the end of the long mat seedling M will be described.
As a seventh alternative configuration example of the seedling stage, the roll holder moving device 32 is provided with the moving device 32 in the roll holder as shown in FIG. That is, the extension part 32s is connected to the base part of the roll holder 10, and left and right position guides 32p and 32p capable of selectively holding the extension part 32s at the upper and lower positions are provided on the seedling stage 11, and the shift operation is performed. A grip 32h is attached to the extension 32s.

  In normal times, including the time when the seedling roll R is mounted, the extension 32s is used as the upper position as shown on the right side of the figure. When the long mat seedling M is drawn from the seedling roll R to the end and the winding portion of the long mat seedling M is lost, the long mat seedling M that has been wound around the seedling roll R until then is separated from the seedling roll R and the same seedling. Since the seedling holding action by the roll R is lost, by moving the extension part 32s to the lower stage position with the grip 32h as shown on the left strip side of the figure so as not to hinder the planting performance, The roll holder 10 can be moved so as to extend with one touch. Therefore, the remaining long mat seedling M can be used as a seedling presser by the winding core C formed of a vinyl chloride pipe or the like without requiring any special pressing means.

  Moreover, a roll holder moving apparatus is a roll holder as an 8th another structural example of a seedling stand, as shown in a side view, the principal part A arrow view, and a principal part enlarged view (ac) in FIG. The right and left support guides 33g, 33g, each having a mounting hole for the ten spindles 10b formed as long holes, and a height adjustment lever 33h for moving the roll holder 10 within the range of the long holes, are provided with a position holder 33p and a desired position. It is configured to be stopped by.

  The moving device 33 of the roll holder can press the seedling against the seedling feeding belt even after the long mat seedling M of the seedling roll R is reduced and separated from the winding core C by lowering the height of the roll holder 10. Therefore, it is possible to avoid a situation in which the force for holding the seedling is lost and the seedling feeding by the transfer belt is incomplete.

(Roll holder support part)
Next, the support part for attaching the roll holder to the seedling stage will be described.
As a ninth alternative configuration example of the seedling stage, as shown in FIG. 12, a side view, an A arrow view thereof, and enlarged views (a to c) of main parts are provided on the seedling stage 11. Left and right guide support members 34 and 34 for guiding the shaft 10b to a predetermined position along the inclination are provided. With these guide support members 34, 34, the roll holder 10 can be mounted at the center position of each strip even if it is slightly shifted laterally.

  Moreover, as a 10th another structural example (six-row planting) of a seedling stage, as shown in FIG. 13 in a side view and its A arrow view (a, b), the seedling stage 11 has an adjacent roll. Left and right support members 35, 35 that receive the support shaft 10b of the holder 10 in a shifted manner are provided. In the 30 cm spacing, the width of the partition portion 11 s serving as a seedling tank fence is only 20 mm, so that the conventional one is thin and the work position is limited so that the support shaft 10 b of the adjacent roll holder 10 does not interfere. Although it was difficult, the support members 35 and 35 do not interfere even if the protruding portion of the support shaft 10b of the adjacent roll holder 10 is large, so that the mounting operation can be performed with ease.

  In this case, the seedling stage 11 is configured so that the supporting shaft 10b of the adjacent roll holder 10 is shifted and the body is symmetrical. By comprising in this way, the balance of the left and right of a body can be made uniform.

  In addition, normal box-shaped mat seedlings do not change the surface pressure on the seedling feeding belt even if the number of seedlings is reduced. However, for seedling supply by seedling rolls, the seedling roll load is applied on the line of the seedling feeding belt. As the remaining seedling roll becomes smaller as the remaining seedling roll is scraped off, the surface pressure decreases as the number of seedlings decreases, and there is a possibility that the seedling feeding force decreases and the feeding amount decreases.

  In order to solve the problem, as an eleventh configuration example of the seedling stage, a magnet 41 is attached to the seedling stage 11 as shown in FIG. 14 which is a side view and its A arrow view (a, b). As the seedling roll side of the holder 10 is lowered, the load that is pulled by the magnet 41 and presses the seedling to the seedling transfer belts 15 and 15 side is increased.

Similarly, the seedling roll R is pulled by a spring in a direction in which the seedling roll R is pressed against the seedling feeding belts 15 and 15, and the force of the spring is weak while the seedling roll is still large, and the seedling roll is used to reduce the seedling roll. As the load of the roll R is reduced, the force of the spring is increased so that the pressing load on the transfer belt does not always change even if the remaining weight of the seedling changes.
By configuring as described above, a constant feeding amount can be ensured regardless of the remaining amount of seedlings.

(Handling of seedling roll)
Next, the seedling roll setting operation will be described. In the operation of setting the seedling roll R to the roll holder 10, the seedling roll R is large and heavy and difficult to carry, so the long mat seedling M is lost during planting. In some cases, it was difficult to carry the seedling roll R to the seedling mount 11.

  In order to solve the above problem, an auxiliary seedling roll is provided at the front part of the planting part as shown in FIG. A seedling roll receiver 57 for setting R is provided on the upper part of the seedling mount 11. By this seedling roll receiver 57, even if the long mat seedling on the seedling mounting base 11 is lost, it can be replaced immediately.

  Further, when the seedling roll R is set, the seedling roll R in the seedling roll storage 53 cannot be directly mounted on the roll holder 10 on the seedling mounting base 11, so it is necessary to place it once somewhere, so that Because there was no place, I had to do it on the shore side.

  In order to solve this problem, as shown in FIG. 16 which is a perspective view of a main part of another configuration example of the seedling transplanter, a pole 52... A seedling roll place (seed roll placing pole) 53 that can be stacked in two stages is provided, a seedling roll placing base 54 is provided on the seedling placing stand 11, and a round step 56 is provided so as to go around the planting part 7.

  The seedling roll stand 54 is provided behind the fertilization tank 55 in the upper third portion of the seedling mounting base 11 which becomes an empty space when the seedling roll R is used. The round step 56 includes a front view, a side view, and a plan view (ac) of another configuration example of the seedling transplanter, as shown in FIG. The rear step 56r behind the planting part 7 and the step 6 of the traveling main body part are connected by a passage step 56s on the side of the machine body.

  When the seedling replenishment time is reached by the seedling roll stand 54, the operator puts the seed roll R in the seedling roll place 53 on the seedling roll stand 54 on the seedling stand 11 before getting down to the round step 56. Once placed, then it goes down to round step 56 to remove the take-up core by a vinyl chloride pipe or the like, and the seedling roll R of the seedling mount 11 can be taken out and attached to the roll holder 10.

  In addition, when the seedling roll R is set, the seedling roll R cannot be set on the roll holder 10 from the operator's seat, and is limited to the planting portion 7. Even in that case, the seedling roll R is lowered into the field. Although it was difficult, since the round step 56 was provided in the last part of the planting part 7, when replenishing seedlings in the field, the seedling roll R can be used without using the round step 56. Can be set in the roll holder 10.

  Moreover, when the seedling roll R is reset in the middle of the field, the seedling roll R can only be placed on the seedling stage 11 from the rear of the planting unit 7, so the operator must go down into the field. However, by the round step 56, the seedling roll R can be reset without getting mud on the shoes without getting off the field.
