Description

A seedling guide member and a seedling transplanting unit having the seedling guide member

The present invention mainly relates to a seedling drawing guide member for guiding a seedlings scraped down from a lower end portion of a seedling mat downward, and a seedling planting machine having the seedling drawing guide member.

Background Art [0002] There has been known a seedling transplanting machine including a seedling-withdrawing guide member for guiding seedlings scraped off from the lower end of a seedling mat downward. Patent Document 1 discloses a seedling-type transplanting machine (a rice-growing machine) having a seedling guide structure as a seedling drawing-out guide member of this kind. The seedling guide structure of Patent Document 1 includes a seedling rack on which a seedling mat is mounted, a seedling rack rail (guide rail) for supporting seedlings at the lower end of the seedling mat in a row, And is installed in a rice plant having a food claw which is planted on the ground. In the rearing period of Patent Document 1, the food claw enters the lower end of the seedling mat to scrape the seedlings to be scratched, and guides the seedlings downward through the seedlings outlet (seedlings passage opening) formed in the seedling rack rail. And the seedling guide structure is installed around the seedling outlet.

More specifically, the seedlings guide structure of Patent Document 1 has a pair of left and right side guide bodies and a front seedling guide body. The left and right pair of side guide bodies extend downward from the seedling outlet. The front seedling guide body is disposed between the front end edge portions of the pair of left and right side guide bodies and extends downward substantially toward both front end edge portions. According to this configuration, in the seedling guide structure of Patent Document 1, the seedlings scraped by the food clove are guided downward while being sandwiched by the pair of left and right side guide members, thereby restricting disturbance in the lateral direction of some kind of posture. In addition, the front surface of the seedlings is guided downward along the front seedling guide body, so that forward disturbance of the seedling posture is also regulated.

Japanese Patent Application Laid-Open No. 2000-175527

However, in the structure of Patent Document 1, the left and right pair of side guide bodies and the front seedling guide body are elongated downward in a state where there is almost no gap between them, as viewed from the side (see Fig. 2 Reference). Therefore, as the seedlings are guided downward while being sandwiched between the pair of left and right side guide members and the front seedling guide member, the portions of the seeds (block portions) are rubbed in the inside of the seedling guide structure to be kneaded, There is a case where the accuracy of the food part is adversely affected. In addition, some of the block portions are rubbed against the seedling guide structure, so that the block portion may collapse. In addition, the soil is deposited inside the seedling guide structure, and the deposited soil obstructs the transportation of the seedlings, resulting in poor food quality.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and its potential object is to maintain the seedlings in a stable state to guide them downward and to plant them on the ground in a state suitable for growing seedlings.

The problem to be solved by the present invention is as described above, and the means for solving the problem and the effect thereof will be described below.

According to a first aspect of the present invention, there is provided a seedling drawing guide member having the following constitution. That is, the seedling drawing-out guide member is a member attached to the seedling-seedling machine having the seedling rack, the guide rail, and the food claw. The seedling mat is loaded with the seedling mat. The guide rail supports a lower end portion of the seedling mat. The food part claw enters the lower end of the seedling mat to scrape off the seedlings to be scratched, passes through the seedling passage formed in the guide rail, and guides the seedlings downward to be planted on the ground. The seedling drawing guide member has a seedling front guide portion and a pair of left and right seedling lateral guide portions. The seedling front guide portion is disposed so as to protrude downward from the front of the food claw passing space which is the space through which the food claw passes after its tip passes through the seedling passage, and is formed to follow the trajectory of the tip of the food claw. The pair of left and right seedling lateral guide portions are disposed so as to protrude downward from the side of the food claw passing space and are connected to the seedling front guide portion at the base end thereof. As shown in FIG.

As a result, the seedling which is kept in the food chloe and guided downward passes between the pair of left and right seedling lateral guide portions. Therefore, it is possible to suppress disturbance in the lateral direction of some scraped postures. At this time, the front face of the seedlings is guided downward along the seedling front guide portion. Therefore, it is possible to suppress the forward hardness (tilt) of the scraped postures. Further, when seen from the side, the pair of left and right seedling lateral guide portions face downward, and the distance from the seedling front guide portion is widened. For this reason, in the seedling which is held down by the food portion and guided downward, the portion of the soil (block portion) comes into contact with the pair of left and right seedling lateral guide portions at the base end portion of the seedling- Thereafter, as the seedlings are guided downward, a portion of the pair of left and right seedling lateral guide portions contacting the seedling gradually moves toward the tip of the leaf, and by the resistance force generated between the pair of left and right seedling lateral guide portions and the seedling, The holding angle with respect to the food claw can be prevented from becoming extremely large due to the centrifugal force. Therefore, the seedlings can be held in a stable posture by the food part claws, can be guided downward, and further, can be planted on the ground in an appropriate posture. In addition, it is possible to prevent the seedlings from escaping from the food claws by the friction force generated between the pair of left and right seedling lateral guide portions and the seedlings. Further, when viewed from the side, since the distance between the seedling front guide portion and the pair of left and right seedling lateral guide portions widens toward the downward direction, the soil is easily discharged downward from inside the seedling drawing guide member, So that it becomes difficult for the soil to accumulate inside the guide member. Therefore, it is possible to prevent the soil from adhering to the seedlings, so that the seedlings can be transplanted well.

In the seedling drawing guide member, it is preferable that the seedling front guide portion and the pair of left and right seedling lateral guide portions are integrally formed.

This brings about the following effects. In other words, conventionally, since the food cloil is held and transported to the ground, a member for guiding the front side of the seedlings, a member for guiding the left side of the seedlings, and a member for guiding the right side of the seedlings are separately provided, The assembly of the battery pack was complicated. In this respect, in this configuration, since the member for guiding the front side of the seedlings which is held by the food portion claw and carried to the ground and the member for guiding the side of the seedlings are integrally formed, assembly is facilitated. Particularly, since the member for guiding the seedlings is brought into contact with the seedlings and the surface is worn, it is necessary to replace them at the time of abrasion. However, in the present construction, the removal of the seedlings is facilitated.

The draw-out guide member preferably has the following configuration. That is, the seedling front guide portion has a curved plate portion curved along the locus of the tip of the food part claw. And at least a part of the curved plate portion has a left-right width larger than an interval between the pair of left and right seedling lateral guide portions.

As a result, it is possible to suppress scattering of the broken soil from a certain kind of block portion scraped from the food clove toward the front of the seedling-drawing guide member. Therefore, it is possible to suppress accumulation of the soil on a member or device (for example, a float) disposed at the front lower side of the seedling guiding member.

The seedling drawing-out guide member is preferably configured as follows. That is, protrusions protruding rearward are formed at left and right central portions of the curved plate portion. The projecting portion is elongated along the trajectory of the tip of the food claw.

This makes it possible to move the food part claw downward along the protruding part and to carry it to the vicinity of the ground while suppressing the falling of the food part claw from the food part claw.

The seedling drawing-out guide member is preferably configured as follows. That is, the seedling-type front guide portion is formed with a bar-shaped guide rod extending downward along the locus of the tip of the food claw from the lower end of the curved plate portion. The projecting portion is formed in a shape continuous with the guide bar.

This makes it possible to transport the seedlings scraped from the food clovers to the vicinity of the ground while suppressing the dropping of the seedlings from the food clogs along the guide rods. In addition, since the seed rod is guided by the rod-like guide rod having a small contact area with the seedlings, adhesion and accumulation of the soil of the seedling mat can be suppressed. In addition, since the shapes are continuous by the projecting portions and the guide rods, the guides can smoothly shift from the guide of the seedling by the projecting portions to the guide of the seed rods by the guide rods.

In the seedling drawing guide member, it is preferable that both of the seedling front guide portion and the left and right pair of seedling lateral guide portions are formed of resin.

As a result, it is possible to prevent the seedling guide member from being broken by the resonance phenomenon by forming the seedling guide member from a material having a large vibration damping different from that of the conventional metal material.

According to a second aspect of the present invention, there is provided a seedling transplanting machine comprising the seedling drawing-out guide member.

As a result, the seedling can be guided downward by keeping the seedling claw in a stable posture, and further, it can be planted on the ground in an appropriate posture. In addition, since the soil is hardly accumulated in the inside of the seedling drawing-out guide member, adherence of the soil to the seedling can be prevented, and the food can be satisfactorily performed.

A PTO shaft 13 for outputting the driving force of the engine 10 to the molding section 3 and an elevating cylinder 14 for elevating and lowering the molding section 3 are provided at the rear portion of the traveling base 2 Respectively.

The elevating link mechanism 12 shown in Fig. 1 is constituted by a parallel link structure including a top link 18, a lower link 19, and the like. An elevating cylinder 14 is connected to the lower link 19. With this configuration, the entire lifting and lowering cylinder 3 can be lifted up and down by extending and contracting the lifting cylinder 14. [

The eating and drinking part 3 mainly includes a food part input case 26, a plurality of (three) food parts 20, a seedling rack 17, and a plurality of floats 16.

Power input to the PTO shaft 13 from the engine 10 via the transmission case 9 is transmitted to the food input case 26 shown in Fig. The power transmitted from the engine 10 via the transmission case 9 is transmitted not only to the front wheel 4 and the rear wheel 5 but also to the food input case 26 of the cooking cavity 3. The food part unit 20 described later is driven by the power transmitted from the food part input case 26 or the seedling bearing stand 17 is reciprocated.

Each food unit (20) has a food-feeding transmission case (27) and a rotary case (21). Power from the food-part input case (26) is transmitted to the eating-part transmission case (27). Two rotary casings 21 are attached to each of the eating-compre- hening transmission cases 27, and each rotary case 21 is configured to perform one pair of food compartments by two pairs of food compartments 22.

Concretely, the rotary case 21 is rotationally driven by the power from the foodtransmission case 27 so that the front ends of the two pairs of food claws 22 are operated so as to draw a looped locus as shown in Fig. 3 Consists of. A seedling (a seedling to be scraped) positioned at the lower end (rear end in the present embodiment) of the seedling mat M placed on the seedling rack 17 to be described later when the front end of the food claw 22 moves from top to bottom, (S) is scraped from the seedling mat (M) and is guided downward by the seedling drawing guide member (50) while keeping the soil (block portion) of the seedling (S) As shown in FIG.

As shown in Fig. 1, the seedling rack 17 is arranged above the food unit 20, and is configured to be able to load the seedling mat M therein. The seedling rack 17 is configured to be reciprocally translatable (slidable in the transverse direction). The seedling rack 17 is configured to vertically feed and transport the seedling mat M intermittently downward from the reciprocating end of the seedling rack 17. With this configuration, the seedling rack 17 can feed the seedlings of the seedling mat M to the respective food units 20. In this manner, in the rice-letting machine 1, a seedling can be sequentially supplied to each of the food units 20, and a seedling can be continuously fed.

The float 16 shown in Fig. 1 is provided at the lower part of the molding part 3, and the bottom surface of the float 16 is disposed so as to be in contact with the ground surface. The floors 16 are brought into contact with the ground so that the rice paddy before the seedling is fed is leveled.

Next, the configuration of the seedling bearing table 17 will be described in more detail with reference to FIGS. 1 to 4. FIG. 4 is a side view showing a detailed configuration around the lower end of the seedling bearing stand 17;

An upper portion of the seedling bearing stand 17 is supported on an upper guide rail (not shown) so that the seedling bearing stand 17 can be moved in the left-right direction of the body. 4, the lower part of the seedling rack 17 is supported by a lower guide rail (guide rail) 28 so that the seedling rack 17 can be moved in the lateral direction of the substrate. The upper guide rails and the lower guide rails 28 are horizontally arranged in the longitudinal direction thereof toward the left and right sides of the base body. 3, the lower guide rail 28 of the present embodiment has a lower end portion (a seedling on the most downstream side in the seedling-length vertical transporting direction) of the seedling mat M loaded on the seedling rack 17, And also functions as a seedling receiving part for supporting the seedling.

The seedling rack 17 is reciprocally moved transversely by a transverse feed mechanism not shown in the figure, and the seedling mat M is intermittently vertically transported downward by a seedling-length vertical transport mechanism (not shown) Lt; / RTI > The transverse feeding mechanism of the seedling rack 17 and the seedling-length vertical feeding mechanism are driven by the power transmitted from the food-part input case 26 shown in Fig. As a result, when the seedling mat 17 is transversely moved reciprocally and the seedling mat 17 on the seedling rack 17 reaches the reciprocating stage (return point of reciprocating movement) Is intermittently vertically transported downward.

As shown in Fig. 1, the seedling rack 17 at the rear of the traveling base 2 is inclined so that the front portion is higher and the rear portion is lower. As shown in Fig. 2, a seedling mat mounting surface (mounting surface) A capable of mounting the seedling mat M is formed on the upper surface of the seedling mounting table 17. The seedling mat mounting surface (A) is constituted by the surfaces exposed on the side of the seedling mat mounting surface forming member (30) and the seedling mat (M) of the lower rail frame (31). Since the rearing unit 1 of the present embodiment is a rearing unit for six-group planting, six (six sets) of seedling bearing surface forming members 30 are provided.

The above-mentioned seedling vertical conveying mechanism is provided at a portion of the seedling mat mounting surface forming member (30). As shown in Fig. 2, each of the seedling-length vertical conveying mechanisms is provided with a pair of left and right endless seedling vertical conveying belts 29 which are partially exposed to the seedling mat mounting surface (A). The seedling vertical conveying belt 29 is driven by placing the rectangular seedling mat M on the seedling mat mounting surface A so that the seedling vertical conveying belt 29 is driven so that the seedling mat mounting surface A on the seedling draw- The seedling mat M is transported vertically. As a result, the seedlings of the seedling mat (M) are scraped by the food compartment claws (22) in order from the seedling vertical transporting direction.

In addition, the seedling rack 17 and the lower guide rail 28 can be displaced with respect to the rotational locus of the food claw 22. Concretely, when the operator manipulates the seedling scraping amount adjusting lever (not shown) to rotate the seedling claw 22 in the same direction, the seedling rack 17 and the lower guide rail 28 are integrally rotated in the direction of arrow (Along a guide rail (not shown)) to displace the position relative to the food claw 22. By this, for example, by moving the seedling rack 17 and the lower guide rail 28 relatively upward with respect to the food claw 22, the entry position of the food claw 22 with respect to the seedling mat M becomes The length in the vertical direction in which the seedlings are scratched out one time can be made smaller than usual. Such a specification is used, for example, to make the number of seedlings scraped off in the case of scraping seedlings from a seedling mat seedlings seeded at a high density substantially equal to the ordinary case.

Hereinafter, the construction of the lower guide rail 28 as a guide rail and its surrounding structure will be described in more detail with reference to FIGS. 4 to 6. FIG. 5 is a perspective view showing a configuration of a seedling passage hole 28n formed in the lower guide rail 28.

The pair of folded back portions is constituted by left folded back portion (40dl) and right folded back portion (40dr). The left folded back portion 40dl horizontally extends a little distance from the rear end of the left mat leading head receiving portion 40cl toward the left side and then the front end portion thereof extends toward the front lower side. That is, the left folded back portion 40dl is folded back from the rear end of the left mat leading head receiving portion 40cl to the outside (left side). A stepped portion 40p is formed in a portion of the left folded back portion 40d1 after folding back. The right folded back portion 40dr horizontally extends a little distance from the rear end of the right mat leading head receiving portion 40cr toward the right side and then the front end portion thereof extends toward the front lower side. That is, the right-side folded-back portion 40dr is folded back from the rear end of the right mat reception portion 40cr to the outside (right side). A stepped portion 40p is formed in a portion of the right folded back portion 40dr after folding back.

A rectangular notch with one side (rear side) opened is formed between the left side mat accommodating portion 40bl and the left side mat accepting portion 40cl and between the right side mat accommodating portion 40br and the right side mat accepting portion 40cr. And a seedling outlet N for extracting the seedlings S scraped off by the food compartment claws 22 is disposed in the notch (details will be described later).

A pair of positioning projections 40s and 40s shown in Fig. 7 are formed in a portion immediately before the pair of the backward folded portions 40d1 and 40dr are brought into contact with each other. The positioning projections 40s protrude from the plane formed by the folded-back portions 40dl and 40dr in a substantially circular column shape substantially perpendicular to the plane. The positioning protrusion 40s can be fitted into the notch 28e formed in the lower guide rail 28. [

The seedling outlet forming member 35 is provided with a takeout guide portion 41 attached to the main body 40. The draw-out guide portion 41 has an end face that faces upward or backward, and a seedling outlet N is formed at an inner portion of the end face. The drawing guide portion 41 guides the seedling S which is drawn out through the seedling draw-out opening N scraped by the food cutting claws 22. The withdrawing guide portion 41 is fixed to the main body 40 by welding or the like.

The withdrawing guide portion 41 includes a supporting boundary guide portion 41a and a pair of receiving boundary guide portions 41l and 41r. The draw-out guide portion 41 of the present embodiment is made of a wear-resistant material such as stainless steel.

The support boundary guide portion 41a shown in Fig. 8 is a plate-like portion extending from the portion where the main body 40 is branched to the left and right toward the front lower side. The support boundary guide portion 41a is located above the seedlings S that have passed through the seedling outlet N and serves to guide the entire surface of the seedlings S. [ The rear end surface of the support boundary guide portion 41a is connected to the curved surface portion 40k of the main body 40. [ A seedling mat support portion 35s is formed on the rear end surface of the support boundary guide portion 41a.

The pair of receiving boundary guiding portions are constituted by a left receiving boundary guiding portion 41 1 and a right receiving boundary guiding portion 41 r.

The left receiving boundary guiding portion 41l has a substantially L-shaped (substantially rectangular) L-shaped guide portion 41a provided continuously to the right end of the left side mat accommodating portion 40bl, the right end of the left mat head receiving portion 40cl and the left end of the support boundary guide portion 41a It is the part of the flat plate shape. The left-side receiving boundary guide section 411 is substantially perpendicular to the left-side mat accommodating section 40bl, the left-side mat acceptance section 40cl, and the support-boundary guide section 41a, And extends in a downwardly tapered shape toward the lower side. That is, the left receiving boundary guide portion 41l extends downward from the boundary portion between the seedling draw-out opening N and the left mat receiving portion 40bl. The left receiving boundary guiding portion 41l is located in the left side room of the seedling S passing through the seedling outlet N and serves to guide the left side of the seedling S. [

The right receiving edge guiding portion 41r is a substantially L-shaped one provided continuously to the left end of the right mat accommodating portion 40br, the left end of the right mat front accepting portion 40cr, and the right end of the support boundary guide portion 41a It is the part of the flat plate shape. The right receiving edge guide portion 41r has a substantially vertical plane with respect to the right mat receiving portion 40br, the right mat receiving portion 40cr, and the support boundary guide portion 41a, and FIGS. 7 and 9 And extends in a downwardly tapered shape as shown. That is, the right receiving boundary guide portion 41r extends downward from the boundary portion between the seedling draw-out opening N and the right mat accommodating portion 40br. The right water receiving boundary guide portion 41r is positioned in the right chamber of the seedling S passing through the seedling outlet N and serves to guide the right side of the seedling S. [

The seedling mat support portion 35s is positioned at a portion connecting the left mat accommodating portion 40bl and the right mat accommodating portion 40br on the opposite side of the open side. The seedling mat support portion 35s is arranged to extend over a part of the curved surface portion 40k of the main body 40 and a rear end surface of the support boundary guide portion 41a of the pullout guide portion 41. [ 9, the seedling mat support portion 35s is provided on the seedling mat loading surface (the seedling mat mounting surface) of the seedling rack 17 when the seedling-exit forming member 35 is attached to the lower guide rail 28 as shown in Fig. 4 and Fig. 9 A is disposed at a location on the downstream side of the seedling mat vertical transportation direction. At the same time, the seedling mat support portion 35s is disposed at a position upstream of the seedling outlet N in the seedling mat longitudinal transporting direction.

The seedling outlet forming member 35 configured in this manner can be fixed to the lower guide rail 28 from the rear side downward. Concretely, the tip end portions of the pair of the folded back portions 40dl and 40dr of the main body 40 are inserted into the groove portion 28f and simultaneously the positioning projections 40s and 40d are inserted into the notched portions 28e and 28e, 40s are inserted, the seedling outlet forming member 35 can be positioned with respect to the lower guide rail 28. As described above, since the left side mat front head receiving portion 40cl and the right side mat head receiving portion 40cr are positioned in the width direction by the positioning projections 40s and 40s, the left side mat front receiving portion It is possible to suppress deformation (e.g., deformation in which the seedling outlet N narrows in the width direction) of the seedling outlet receiving portion 40cr and the right mat receiving portion 40cr and to maintain the strength of the seedling outlet forming member 35 .

In this state, the positions of the attachment holes 40h and 40h of the attaching flat portion 40a are aligned with the screw holes (not shown) formed on the bottom surface of the fitting portion 28a of the lower guide rail 28, The screw hole is screwed into the screw hole to fasten the seedling outlet forming member 35 to the lower guide rail 28. In addition, for the lower guide rail 28, in addition to the seedling outlet forming member 35, the seedling receiving guide member 50 is also attached by means of the cavity fastening, but this will be described later.

The seedling S to be scraped arranged above the seedling outlet N of the seedling outlet forming member 35 thus formed is cut out from the seedling mat M by the action of a shearing force as indicated by an arrow in Fig. . Fig. 9 is a side sectional view showing a state in which a seedling S to be scratched is cut out from the seedling mat M; Fig.

In detail, the bottom surface (bottom surface of the mat portion) of the seedlings immediately above the seedlings S to be scratched is supported by the seedling mat support portion 35s. The seedlings are scraped in order from the left and right ends of the seedling mat M toward the other end by the reciprocating movement of the seedling rack 17 described above, but the seedlings S Is supported by the upper surface of the left mat receiving portion 40bl and the left receiving guide portion 41l or the upper surface of the right mat receiving portion 40br and the right receiving guide portion 41r. 9, when the food claw 22 enters the seedling S to be scratched, the seedling S receives the force F1 acting in the food claw entering direction from the food claw 22, . Simultaneously with this, the seedling (S) receives a force (F2) acting in a direction opposite to the direction in which the food cloth is introduced from the seedling mat support portion (35s). 9, the upper side of the left mat accommodating portion 40bl and the left accommodating boundary guide portion 41l, or the upper side of the right mat accommodating portion 40br and the right accommodating boundary guide portion 41r from the upper side of the food closure entrance. As a result, a shearing force acts on the seedling S to be scratched, and the seedling S is cut out from the seedling mat M.

In the conventional seedling transplanting machine, a seedling receiving frame for supporting the lower end portion of the seedling mat is provided at the lower end of the seedling mat on which the seedling mat is loaded so that the seedling claw enters the seedling receiving frame to draw the seedling to be scraped It is known that seedling outlets are formed. In this type of seedling transplanting machine, generally when scraping seedlings out of the seedlings, the seedlings are introduced into the foodcloth while supporting the seedlings mat at the lower end of the seedlings. Therefore, there was a relatively long distance between the position where the seedling mat is supported from below and the entry position of the food claw. As a result, the lower end portion of the seedling mat may be rattled. In addition, for the same reason, when the seedlings to be scratched are cut from the seedling mats by the shear force, the stress can not be sufficiently concentrated.

9, the lower end AE of the seedling mat mounting surface A is located on the downstream side in the seedling lengthwise transporting transport direction and the seedling outflow opening N is larger than the seedling outflow opening N. In this manner, Since the seedling mat support portion 35s is disposed at a position on the upstream side in the vertical transfer conveying direction, the bottom end portion of the seedling mat M is supported by the seedling mat support portion 35s from below. Therefore, the lower end portion of the seedling mat M is less prone to hang than the conventional structure. The distance between the position where the seedling mats M are supported from below (in this embodiment, the position at which the seedlings mats are supported by the seedling mat support portion 35s corresponds to this) and the entry position of the food claws 22 The seedlings S to be scratched can be cut off from the seedling mat M by the shearing force with a sufficient concentration of stress and can be cut well. Especially when the seedling rack 17 and the lower guide rail 28 are displaced upward relative to the rotation locus of the food compartment claw 22 so that the length of the scraping of the seedlings in the longitudinal direction is shortened, And the lower end of the mat (M) is supported from below by the seedet mat support portion (35s), so that a stable seedling scraping can be realized.

In the pancake machine 1 of the present embodiment, the seedling outlet forming member 35 is detached from the lower guide rail 28 so that the seedling outlet forming member 35 is larger than the seedling outlet forming member 35, (For example, a standard seedling outlet forming member 61 to be described later). Alternatively, the seedling-exit forming member 35 may be removed to use the seedling-seed-passing opening 28n as a seedling outlet. For example, in a case where a pair of the rearing machines 1 is used to scrape a short raking length from a seedlings mat which has been seeded at a high density, and a case where a normal raking length is scraped from a seedlings mat with seedlings at a general density Good scraping can be performed on both sides.

Hereinafter, the configuration of the seedling-guiding member 50 will be described in detail with reference to FIGS. 10, 11, and the like. Fig. 10 is a perspective view showing the detailed configuration of the seedling drawing-out guide member 50. Fig. 11 is a perspective view showing the detailed structure of the seedling drawing-out guide member 50 when viewed from an angle different from that of Fig.

As shown in Figs. 4 and 9, the seedling drawing guide member 50 shown in Figs. 10 and 11 is fastened to the mating portion 28a of the lower guide rail 28 by using the bolts 45, (28n).

As shown in Figs. 10 and 11, the seedling drawing-out guide member 50 has a flat portion 50a for attachment, a seedling-front guide portion 50b, and a pair of seedling lateral guide portions 50cl and 50cr. In the present embodiment, the attaching flat portion 50a, the seedling front guide portion 50b, and the pair of seedling lateral guide portions 50cl and 50cr are all formed of resin and are integrally molded as a whole of the seedling- .

The attaching flat portion 50a is a flat plate-like portion having a substantially rectangular shape. A notched portion 50n having a rectangular shape is formed at the left and right central portions of the attaching flat portion 50a. Mounting holes 50h are formed on the left and right sides of the notched portion 50n of the attaching flat portion 50a. The above-described bolt 45 is inserted into the attachment holes 50h and 50h with the open side of the notch portion 50n facing rearward so that the seedling draw- And is attached to the fitting portion 28a of the lower guide rail 28 by being fastened.

The seedling front guide portion 50b is formed so as to protrude downward from the front of the food claw passing space X which is a space through which the tip end of the food claw 22 passes after passing through the seedling passage opening 28n (seedling outlet N) . The seedling front guide portion 50b is formed in a shape along the trajectory of the distal end of the food claw 22.

More specifically, the seedling front guide portion 50b has a curved plate portion 50d, a projection portion 50e, and a guide rod 50f as shown in FIG. 10 and the like. The seedling front guide portion 50b is a plate-shaped portion curved along the trajectory of the tip end of the food claw 22. In the present embodiment, the curved plate portion 50d of the seedling front guide portion 50b has a larger width across the whole than the interval between the pair of seedling lateral guide portions 50cl and 50cr. The projecting portion 50e is formed so as to protrude rearward from the right and left central portions of the curved plate portion 50d. The projecting portion 50e is elongated along the trajectory of the distal end of the food claw 22. The guide bar 50f is a rod-shaped portion provided so as to be continuous with the lower end of the protruding portion 50e and extending downward. The guide rods 50f are installed so as to follow the trajectory of the tip end of the food claw 22.

The pair of seedling lateral guide portions are composed of a left seedling lateral guide portion 50cl and a right seedling lateral guide portion 50cr.

And the left seedling lateral guide portion 50cl is disposed so as to protrude downward from the left chamber of the food claw passing space X. [ The left seedling lateral guide portion 50cl is connected to the curved plate portion 50d of the seedling front guide portion 50b at its base end. In other words, the left seedling lateral guide portion 50cl has no gap between the left seedling lateral guide portion 50cl and the curved plate portion 50d when viewed from the side (when viewed from the direction of the lateral feeding movement of the seedling rack 17) State. The distance between the left seedling lateral guide portion 50cl and the curved plate portion 50d is gradually widened toward the downward side when viewed from the side. When the seedling draw-out formation member 35 and the seedling draw-out guide member 50 are attached to the lower guide rail 28, the inner surface of the left seedling lateral guide portion 50cl The outer side surface of the left receiving boundary guiding portion 411 is brought into contact with and is in contact with the surface of the left side receiving boundary guide portion 411.

The right side seedling lateral guide portion 50cr is disposed so as to protrude downward from the right chamber of the food claw passing space X. [ The right side seedling side guide portion 50cr is connected to the curved plate portion 50d of the seedling front guide portion 50b at its base end. In other words, when viewed from the side, the right seedling lateral guide portion 50cr is in a state in which there is no gap between the right end seedling lateral guide portion 50cr and the curved plate portion 50d. When viewed from the side, the distance between the right side seedling lateral guide portion 50cr and the curved plate portion 50d gradually widens toward the downward direction. When the seedling-draw forming member 35 and the seedling draw-out guide member 50 are attached to the lower guide rail 28, the inner side surface of the right seedling lateral guide portion 50cr The outer side surface of the right receiving boundary guiding portion 41r is in contact with and follows the surface of the right receiving boundary guide portion 41r.

Next, the manner in which the seedling S is guided downward by the seedling guiding member 50 constructed as described above will be described with reference to Fig. Fig. 12 is a side view showing a state in which the scraped seedling S is guided by the seedling-guiding member 50. Fig.

The seedling S after passing through the seedling passage 28n (seedling outlet N) is guided by the seedling guide member 50 described above (see Fig. 12) The guided seedlings S pass between a pair of left and right seedling lateral guide portions 50cl and 50cr. Therefore, the posture of the scraped seedling (S) in the lateral direction can be suppressed. At this time, the front face of the seedling S is guided downward along the seedling front guide portion 50b. Therefore, the forward hardness of the posture of the scraped seedling (S) can be suppressed. Further, when seen from the side, the distance between the pair of seedling lateral guide portions 50cl and 50cr from the seedling front guide portion 50b is widened toward the downward direction. Therefore, in the seedling S held by the food claw 22 and guided downward, the block portion is stuck to a pair of the left and right pair of seedling lateral guide portions 50cl and 50cr at the base end of the seedling drawing guide member 50 to be hardened to some extent It is not hardened in excess. In addition, it is possible to prevent the seedling S from becoming an extreme forward walking posture due to the resistance force generated between the seedling S and a pair of left and right seedling lateral guide portions 50cl and 50cr. Further, Lt; / RTI > Since the gap between the seedling-side front guide portion 50b and the pair of left and right seedling lateral guide portions 50cl and 50cr widens downward when viewed from the side, It becomes difficult for the soil to accumulate inside. Therefore, it is possible to prevent the situation that the deposited soil is adhered to the seedling (S) to cause defective food.

As described above, the seedling draw-out guide member 50 of this embodiment is a member attached to the rice plant 1 having the seedling rack 17, the lower guide rail 28, and the food claw 22 . A seedling mat (M) is loaded on the seedling rack (17). The lower guide rail 28 supports the lower end portion of the seedling mat M. The food compartment claw 22 enters the lower end portion of the seedling mat M to scrape off the seedling S to be scratched and passes through the seedling passage opening 28n formed in the lower guide rail 28, ), And plant it on the ground. The seedling guiding member 50 includes a seedling front guide portion 50b and a pair of left and right seedling lateral guide portions 50cl and 50cr. The seedling front guide portion 50b is disposed so as to protrude downward from the front of the food claw passing space X which is a space through which the food claw 22 passes after its tip passes through the seedling passage 28n, 22 along the trajectory of the tip end. The pair of left and right seedling lateral guide portions 50cl and 50cr are arranged so as to protrude downward from the lateral side of the food claw passing space X and are connected to the seedling front guide portion 50b at the base end thereof, And the distance from the seedling front guide portion 50b is gradually widened toward the lower end.

As a result, the seedling S held by the food claw 22 and guided downward passes between the pair of left and right seedling lateral guide portions 50cl and 50cr. Therefore, it is possible to suppress disturbance in the lateral direction of the attitude of the scraped seedling (S). At this time, the front face of the seedling S is guided downward along the seedling front guide portion 50b. Therefore, the forward hardness of the posture of the scraped seedling (S) can be suppressed. In addition, when viewed from the side, the pair of left and right seedling lateral guide portions 50cl and 50cr are widened toward the downward direction and spaced from the seedling front guide portion 50b. Therefore, the seedlings S held by the food claws 22 and guided downward can be easily removed from the seedlings at the base end of the seedlings guide member 50 by the contact of the soil portions (block portions) with the left and right seedling lateral guide portions 50cl To some extent. Thereafter, as the seedlings S are guided downward, a portion where the pair of left and right seedling lateral guide portions 50cl and 50cr are in contact with the seedling S gradually shifts toward the tip of the leaf, The holding angle with respect to the food claw 22 of the seedling species S can be prevented from becoming extremely large due to the centrifugal force due to the resistance force generated between the guide portions 50cl and 50cr and the seedling S. [ Therefore, the seedlings S can be guided downward by keeping the food claws 22 in a stable posture, and further, they can be planted on the ground in an appropriate posture. It is also possible to prevent the seedling S from being detached from the food claw 22 due to the frictional force generated between the pair of left and right seedling lateral guide portions 50cl and 50cr and the seedling S. Since the spacing between the seedling front guide portion 50b and the pair of left and right seedling lateral guide portions 50cl and 50cr widens downward when viewed from the side, The inside of the seedling guide member 50 is hardly deposited black. Therefore, it is possible to prevent the soil from adhering to the seedlings, so that some types of food can be satisfactorily performed.

In the seedling drawing guide member 50 of the present embodiment, the seedling front guide portion 50b and the pair of left and right seedling lateral guide portions 50cl and 50cr are integrally formed.

This brings about the following effects. In other words, conventionally, since a member for guiding the front surface of a seedling, a member for guiding the left side surface of the seedling, and a member for guiding the right side surface of the seedling are separately provided when the food is kept in the chlorine- The member had to be positioned and the assembling to the guide rail was troublesome. In this configuration, in this constitution, the member (the seedling front guide portion 50b) for guiding the front side of the seedling S to be held by the food claw 22 and carried to the ground, and the member for guiding the side face of the seedling S The pair of left and right seedling lateral guide portions 50cl and 50cr) are integrally formed, so that assembly is facilitated. Particularly, since the member for guiding the seedling S comes into contact with the seedling S and wears on the surface, it is necessary to replace the seedling S when it is worn out. However, in the present construction, the removal and removal of the seedling guiding member 50 is simplified, Thereby improving the stability.

In the seedling drawing guide member 50 of the present embodiment, the seedling front guide portion 50b has a curved plate portion 50d which is curved along the trajectory of the tip end of the food claw 22. [ The left and right widths of at least some of the curved plate portions 50d are larger than the distance between the pair of left and right seedling lateral guide portions 50cl and 50cr.

This makes it possible to suppress scattering of the broken soil from the block portion of the seedling (S) scraped by the food part claws 22 toward the front side of the seedling-drawing guiding member (50). Therefore, it is possible to suppress accumulation of the soil on a member or device (for example, a float) disposed on the lower side of the front side of the seedling guide member 50.

In the seedling drawing guide member 50 of the present embodiment, a projecting portion 50e protruding rearward is formed at the left and right central portions of the curved plate portion 50d. The projecting portion 50e is elongated along the trajectory of the distal end of the food claw 22.

As a result, the food claw 22 can be moved downward along the projecting portion, and it is possible to transport the seedling S scraped by the food claw 22 to the vicinity of the ground while suppressing falling from the food claw 22 have.

In the seedling front guide portion 50b of the seedling guiding member 50 of the present embodiment, the rod-like guide rods 50f from the lower end of the curved plate portion 50d are moved downward along the locus of the tip end of the food claw 22 As shown in Fig. The projecting portion 50e is formed in a continuous shape with the guide rod 50f.

This makes it possible to transport the seedlings S scraped by the food claws 22 to the vicinity of the ground while suppressing the dropping of the seedlings S from the food claws 22 along the guide rods 50f. Further, since the seedling S is guided by the rod-like guide rods 50f having a small contact area with the seedlings S, attachment and deposition of the soil of the seedling mat can be suppressed. Since the formation is continued by the projecting portions 50e and the guide rods 50f, the projecting portion 50e smoothly shifts from the guide of the seedling S to the guide of the seedling S by the guide rods 50f .

In the seedling drawing guide member 50 of the present embodiment, both the seedling front guide portion 50b and the pair of left and right seedling lateral guide portions 50cl and 50cr are formed of resin.

This can prevent the seedling guide member 50 from being broken by the resonance phenomenon, which is formed of a material having a large vibration damping different from that of the conventional metal material.

The rice planting machine 1 of the present embodiment includes the seedling drawing-out guide member 50.

As a result, the seedling S can be guided downward by keeping the seedling claws 22 in a stable posture, and moreover, can be planted on the ground in an appropriate posture. In addition, since the soil is hardly accumulated on the inside (inside) of the seedling drawing-out guide member 50, adherence of the soil to the seedlings can be prevented, and the food can be satisfactorily performed.

The seedling outlet forming member 35 of this embodiment is attached to the rice planting unit 1 having the seedling rack 17, the lower guide rail 28 and the food claw 22. The seedling rack 17 has a seedling mat mounting surface A on which the seedling mat M can be stacked and is capable of reciprocating in the transverse direction and the seedling mat M is intermittently transported vertically And is configured to be transportable. The lower guide rail 28 supports the lower end portion of the seedling mat M. The food compartment claw 22 enters the seedling mat M supported by the lower guide rail 28 to scrape the seedling S to be scratched and to guide the seedling S downward to be planted on the ground, So as to draw the rotation locus. This seedling outlet forming member 35 changes the scraping amount in the longitudinal direction of the food claw 22 by displacing the seedling rack 17 and the lower guide rail 28 with respect to the rotation locus of the food claw 22 Is attached to the lower guide rail 28 in order to form a seedling outlet N for pulling out the seedlings S scraped off by the food composting claws 22 in the possible constitution. This seedling outlet forming member 35 is positioned on the downstream side of the seedling mat vertical transporting transport direction with respect to the lower end AE of the seedling mat mounting surface A of the seedling pallet 17, And a seedling mat support portion (35s) disposed at a position on the upstream side in the transporting direction and supporting the seedling mat (M).

As a result, the food claw 22 enters the seedling mat M in a state in which the seedling mat M is supported by the seedling mat supporting portion 35s of the seedling-outlet forming member 35, The seedling S to be scratched can be scraped off by the food compartment claw 22 in a stable state without rattling. Even when the positions of the seedling rack 17 and the lower guide rail 28 are displaced so that the amount of scraping in the longitudinal direction of the food claw 22 is reduced, even when the position between the seedling mat support portion 35s and the seedling outlet N So that the seedling mat 22 can be scratched smoothly by applying a strong shearing force to the seedling mat M at the boundary portion.

The seedling outlet forming members 35 of the present embodiment further include mat receiving portions 40bl and 40br which are arranged in pairs with the seedling outlet N therebetween. The seedling outlet N is formed as a notch that opens one side. The seedling mat supporting portions 35s connect the mat receiving portions 40bl and 40br to each other on the opposite side from the opening side of the seedling draw-out opening N.

As a result, a portion connecting the mat storage portions 40bl and 40br arranged in pairs can be used as the seedling mat support portion 35s, thereby making it possible to construct the seedling seedling outlet N reasonably.

The seedling outlet forming members 35 of this embodiment are arranged along the contour of the seedling outlet N and are scraped by the food slaw 22 to guide the seedling S having passed through the seedling outlet N, And a guide portion 41. The drawing guide portion 41 has a supporting boundary guide portion 41a extending from a boundary portion between the seedling draw-out opening N and the seedling mat supporting portion 35s. The support boundary guide portion 41a is positioned above the seedlings S that have passed through the seedling outlet N.

As a result, it is possible to prevent the portion (mat portion) of the seedling S that has been scraped by the food claw 22 and passed through the seedling draw-out opening N from being guided from above and scattered. In addition, the posture of the seedlings S can be adjusted.

The draw guide portion 41 of the seedling draw-out opening forming member 35 of this embodiment has the receiving boundary guide portions 41l and 41r extending from the boundary portion between the seedling draw-out opening N and the mat accommodating portions 40bl and 40br Respectively. The receiving boundary guiding portions 41l and 41r are positioned laterally of the seedling S having passed through the seedling outlet N. [

Thus, the portion (mat portion) of the seedling S which has been scraped by the food claw 22 and has passed through the seedling outlet N can be guided from the side so as not to be scattered. In addition, the posture of the seedlings S can be adjusted.

It is possible to attach the seedling draw-out opening forming member 35 to the lower guide rail 28 in the plowing machine 1 of the present embodiment. The transfer station 1 removes the seedling outlet forming member 35 from the lower guide rail 28 and removes the seedling outlet forming member 35 from the seedling outlet forming member 35 (for example, The standard seedling outlet forming member 61 described later).

By this, by displacing the seedling tray 17 and the lower guide rail 28 with respect to the rotation locus of the food tray claw 22, the seedling outlet forming members are exchanged to form a pair of the changers 1, Good scraping can be performed both in the case of scraping by a short raking length from the seedlings mat M subjected to seedling cultivation at high density and in the case of scraping by a normal scraping length from a seedlings mat with seedlings grown at a general density . As a result, the versatility of the herbicide 1 can be improved.

Next, a seedling outlet forming member 60 provided in a rice-growing machine 1 according to a modification of the embodiment will be described with reference to Figs. 13 to 15. Fig. In the following description, the same or similar members to those of the above-described embodiments are denoted by the same reference numerals and the description thereof may be omitted.

First, a standard seedling outlet forming member 61 used for seed dough of general density will be described with reference to Fig. 13 is a perspective view showing a detailed configuration of a standard seedling outlet forming member 61 to be attached to a lower guide rail 28 alone when the amount of scraping is normal.

The standard seedling outlet forming member 61 shown in FIG. 13 has substantially the same structure as the seedling outlet cover described in the above-mentioned Patent Document 1. The standard seedling outlet forming member 61 is used by being attached to the lower guide rail 28 alone when the scraping amount is set to be normal (general scraping amount).

The standard seedling draw-out forming member 61 includes the flat portion 61a for attachment, the mat receiving portions 61bl and 61br, the mat head receiving portions 61cl and 61cr, the folded-back portions 61dl and 61dr, And mainly includes the projections 61s and 61s.

[ Like portion extending from the position on the downstream side in the longitudinal direction of the seedlings in the vertical transport direction toward the front lower side. The support boundary guide portion 62a is located above the seedlings S that have passed through the seedling outlet N2 and serves to guide the entire surface of the seedlings S. [

The pair of receiving boundary guide sections 62bl and 62br are constituted by a left boundary guide section 62bl and a right boundary guide section 62br.

The left boundary guide portion 62bl is a plate-like portion provided so as to be continuous with the left end of the support boundary guide portion 62a. The left side boundary guide portion 62bl extends downward and rearward upward substantially in a vertical direction with respect to the support boundary guide portion 62a. When the seedling mat support member forming member 62 is attached to the lower guide rail 28 together with the standard seedling outlet forming member 61, the contour of the left seedling exit N1 formed by the standard seedling outlet forming member 61, The shape of the left boundary guide portion 62bl is formed.

The right side boundary guide portion 62br is a flat plate-like portion provided so as to be continuous with the right end of the support boundary guide portion 62a. The right side boundary guide portion 62br extends downward and rearward upward substantially in a vertical direction with respect to the support boundary guide portion 62a. When the seedling mat support member forming member 62 is attached to the lower guide rail 28 together with the standard seedling outlet forming member 61, the outline N1 of the seedling outlet N1 formed by the standard seedling outlet forming member 61, The shape of the right boundary guide portion 62br is formed.

The pair of attaching stays 62cl and 62cr are constituted by a left attaching stay 62cl and a right attaching stay 62cr. The left attachment stay 62cl is provided so as to be continuous with the upper surface of the rear end portion of the left boundary guide portion 62bl and extends toward the left in a direction substantially perpendicular to the left boundary guide portion 62bl. An attaching hole 62h for inserting a dish screw is formed in the left attaching stay 62cl. The right attachment stay 62cr is provided so as to be continuous with the upper surface of the rear end portion of the right side boundary guide portion 62br, and extends toward the right substantially vertically with respect to the 62br. The right attachment stays 62cr are formed with attachment holes 62h for inserting dish screws.

15, the standard seedling draw-out opening forming member 61 is attached to the lower guide rail 28 in the same manner as in the seedling draw-out opening forming member 35 of the above embodiment. 15, the seedling mat supporting member forming member 62 is additionally attached to the standard seedling outlet forming member 61. In this case, as shown in Fig. The attachment can be performed by inserting dish screws (fixing members) into the respective attachment holes 62h and screwing them into the screw holes 61h. As a result, the seedling outlet forming member 60 of this modification can be formed.

The rear end face 62e of the supporting boundary guide portion 62a of the seedling outlet forming member 60 is made to be higher than the lower end AE of the seedling mat mounting surface A of the seedling rack 17, The downstream side in the transport direction, and the upstream side in the vertical direction transport direction of the seedling mat from the seedling outlet N2. The rear end surface 62e is disposed on substantially the same plane as the receiving surface of the mat receiving portions 61bl and 61br of the standard seedling outlet forming member 61. [ The rear end surface 62e functions as a seedling mat support portion 60s for supporting the seedling mat M. [ The seedling outlet N2 of the seedling outlet forming member 60 is smaller in the longitudinal direction as well as in the lateral direction than the seedling outlet N1 originally formed in the standard seedling outlet forming member 61. [

In the plowing machine 1 according to this modified example, the position of the downstream side (AE) of the seedling mat mounting surface (A) is the position on the downstream side in the seedling lengthwise transporting conveying direction and the position on the upstream side of the seedling- The rear end portion of the seedling mat M is supported by the seedling mat support portion 60s from below because the seedling mat support portion 60s (that is, the rear end portion 62e described above) is disposed. Therefore, the lower end portion of the seedling mat M is less likely to be rattled than the conventional structure, and the stress can be concentrated from the seedling mat M when the seedling S to be scratched is cut off by the shear force.

In the rearing machine 1 of the present modification, when it is desired to change the scraping amount of a seedling from a normal amount to a small amount, the standard seedling outlet forming member 61 attached to the lower guide rail 28 is removed By attaching the seedling mat support member forming member 62 from above the standard seedling outlet forming member 61 without attaching the seedling mat supporting member 62 to the standard seedling outlet forming member 61. Therefore, there is an advantage that the scraping amount of the seedling can be easily changed.
