Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for digging grass seedlings, and in particular, enables labor-saving and efficient digging work from the nursery and the subsequent mud-driving work. Depending on the situation, it is devised so that the stock splitting work and the height cutting work can be completed continuously.

[0002]

2. Description of the Related Art In general, with regard to grass seedlings for transplanting rhizomes,
It is necessary to temporarily dig the parent roots of the large roots that have become agglomerated into stems from the nursery and divide them into stems with 7 to 8 new shoots suitable for planting in Honda-about 3 to 5 seedlings. ,
Before obtaining the planted seedlings, it is necessary to carry out the work of removing the above-mentioned root mud and, if necessary, the work of cutting the roots and stems.

Japanese Unexamined Patent Publication (Kokai) No. 3-2 has already been proposed as a digging machine for saving labor in such heavy labor and long manual labor.
No. 06813 has been proposed, and as a mud-removing and stock-dividing device after the excavation, JP-A-55-85303, JP-A-63-107109, JP-A-3-54110 and the like are known.

[0004]

However, according to the above-mentioned Japanese Laid-Open Patent Publication No. 3-206813, the hydraulic cylinder (16) is constructed with the suspension shaft (13) whose digging portion is located substantially in the center of the airframe as a fulcrum because of its structure. ), The cutting depth (root cutting length) of the rush seedling (9) by the blade (1) becomes at random. This is because the reference member or the control member for keeping the digging depth from the nursery bed constant is not equipped at all.

In other words, this digging machine is constructed so that it is sufficient to simply dig the parent stock of the sapling (9) from the nursery. However, the work of trimming the roots and stems must be done manually, and it still takes a lot of time and labor. Since excavation of grass seedlings is usually performed on the day of planting on Honda or the day before,
The above-mentioned manual work is a heavy labor that reaches night.

Further, although the above-mentioned excavator is provided with a mud-removing device, the claws (10) to be planted from the shaft (11) for that purpose are moved in the left-right direction by reciprocating half rotation of the shaft (11). Claws (10) that only swing and are adjacent to each other
It may be the result that the grass seedlings (9) are located in the mutual space of.

[0007] Therefore, in particular, in order to surely drop the mud from the roots that have been solidly agglomerated by violently entangled hair roots and adhered to the mud, it is not possible to impart an effective massage and loosening action in a short time without fail. .. Furthermore, as described above, since the structure is such that only excavation is required, as shown in FIG. 23, a large amount of mud adheres to agglomerate and agglomerate under the excessive depth (T) for safety. It will be dug out as a root, and it will be necessary to add the following complicated manual work for assisting mud removal.

On the other hand, in the case of the invention of the above-mentioned Japanese Patent Laid-Open No. 55-85303, the parent strain (12) of rush seedling is the high-speed feed gear (6).
And the low-speed feed gear (6 ') are bitten into each other to be stripped off, but both feed gears (6) (6') have provisional protrusions. Since the 雖 also only makes a simple rotational movement in the reciprocal direction, it can efficiently loosen and loosen the densely entangled root nodules of the parent strain (12) and surely remove the mud attached to it. No, and therefore without both cutters (9) acting on both feed gears (6), (6 '), it is not possible to split it into smaller substocks and the cutter (9) is prematurely damaged. ..

Further, in the above-mentioned Japanese Utility Model Laid-Open No. 63-107109, a pair of endless chain bands (1) with needles (2) are installed side by side in a substantially V-shape when viewed from the front, and the above-mentioned Japanese Utility Model Laid-Open No. 3-107109. 5
No. 4110 device also has a conveyor belt (2) with a protrusion (2a).
The pair A) is also facing the V-shape when viewed from the front.
Then, in the narrow bottom valley part, the parent strain (A) of the grass seedling is divided into the child strain (a).

However, in both known devices, the needle (2) and the protrusion (2a) only pierce the root mass of the parent strain (A), so to speak, and the entanglement of the root mass is loosened. , It is impossible to remove mud from now on. Even though the root mass of the parent strain (A) is in a solid state in which the root mass of the parent strain (A) is strongly entangled with each other, the pair of endless chain belts (1) and the conveyor belt (2A) are After all, it is only a roundabout movement in opposite directions.

From that meaning, even if the claws (10) (19a) for scraping off the sub-stock are added, the actual number of them is 3-
Even if a leaf spring elastic holding mechanism (20) is installed as in the invention of No. 54110, the dividing action itself to the child strain (a) is not surely achieved in the first place, and as a result, from the narrow bottom valley portion. With the nails (10) (19a), the timing of scratching off the child strain (a) is also likely to be incorrect.

[0012]

Therefore, as a method of digging grass seedlings, first, the upper surface of the traveling vehicle body is used as a seedling loading deck, A rotating work frame is pivotally attached to the vehicle body via a horizontal fulcrum shaft, and the work frame is
In addition to the sled sledge that projects integrally to the lower front, a seedling digging mechanism driven by the onboard engine of the vehicle body, a seedling raising mechanism, a parent stock holding and transporting mechanism, and a parental massaging and loosening transport mechanism are intensively equipped. , The roots of the grass seedlings were also set up under the standing posture in which the stems of the grass seedlings to be planted from the nursery were raised by the above-mentioned raising mechanism and the raised stems were clamped by the parent pinching and conveying mechanism. After cutting to a certain depth with the stable grounding surface of the sled as a reference by the excavating mechanism, the stem of the excavated parent stock is directly transferred to the loading deck of the car body by the parent sandwiching and conveying mechanism. In the process of nipping and conveying upwards, characterized by imparting a crushing and disassembling action of the root by the above-mentioned parent crushing and loosening transfer mechanism,

Secondly, the rotating work frame is also equipped with a carving mechanism for dividing parent stocks into child stocks and a height-cutting and aligning mechanism so that the stems of the parent stocks dug from the seedbed can be directly carried by the parent holding machine. , In the process of nipping and transporting upward to the loading deck of the car body, in addition to the root loosening and disassembling action of the parent massaging and loosening transport mechanism, the parental to substock splitting action by the scoring and transporting mechanism and the above-mentioned length cutting It is also characterized in that the aligning mechanism also imparts a cutting and aligning action of the tip end of the offspring.

According to the above configuration of the first invention, completely different from the publicly known technique described at the beginning, by excavating the excavation work vehicle forward in the nursery, the excavation work from the nursery and the excavation thereof are performed. It is possible to automatically and efficiently remove the root mud, and if the above-mentioned configuration of the second invention is adopted, the subdivision work from the parent stock to the sub stock and the height of the sub stock are carried out following the mud removal work. Since the trimming work can be performed consistently, the optimum grass seedling for planting on Honda can be easily obtained.

Since it is connected via transmission,
2) (73) is the stem-holding conveyor belt (6) of the parent strain (M1).
Compared to 2), it will rotate at a higher speed.

That is, the stalk (a) of the parent strain (M1) is transferred from the stalk pinching / conveying belt (62) of the parent pinching / conveying mechanism (E) to the stalk receiving / conveying pinching / conveying belt (72) of the divided conveying mechanism (F) ( 73) In the process of handing over to the carrier, the parent stock (M1) is instantly separated from the parent stock (M1) due to the speed difference, and then the parent stock (M1) is carved into the child stock (M2). It can be quickly conveyed to the upper rear side toward the loading deck (19).

In this respect, in the illustrated embodiment, from the rotation ratio of the reduction pulley (78) and the speed increasing pulley (79),
By increasing the transfer speed of the stalk receiving and sandwiching and conveying belt (72) (73) to about twice as fast as that of the stalk sandwiching and conveying belt (62), the number of stems to which 7 to 8 new shoots are attached-3 to It can be divided into 5 offspring strains (M2) and used directly as planting seedlings for Honda, but the speed difference can be appropriately selected other than double the above.

A large number of protrusions (8) that have a considerably wide sandwiching surface and that stick into the root (b) of the parent strain (M1) or crush the root (b) from the sandwiching surface.
2) is projected in an almost evenly scattered distribution state as a whole.

When the number of groups of such convexes (82) is to be extended and installed, for example, as shown in FIG. 20, a link with a claw of a silent chain is so-called along both adjacent front and rear and left and right directions. By pivotally connecting in a zigzag arrangement, the wide holding surface of the root holding and conveying chain (81) can be finished by the number of groups of the links with the claws.

However, as long as the mud attached to the root (b) of the parent strain (M1) is dropped, the root-holding and conveying chain (81) can be silently operated as long as the nodule of the root (b) can be dismantled. It is formed from a wide belt crawler or the like that replaces the chain, and its convex surface has a piercing or crushing force on the root (b) of the parent strain (M1) (8).
The number of groups of 2) may be integrally projected and distributed.

The fixed arm (83) and the swing arm (84) are fitted in a pivotally supported state so that they cannot be removed from the lower side and can rotate relative to the respective arms (83) (84).

Reference numeral (87) denotes the oscillating gear case (8) as a bearing in a freely rotatable state by the respective bearing port tubes (86).
5) A pair of chain drive shafts drawn upward from both left and right ends, and chain drive sprockets (88) are fitted to the upper ends of the chain drive shafts so as to rotate integrally. And each chain drive sprocket (88)
Further, the front end portion of the root-holding and conveying chain (81) is wound around so as to be able to circulate.

Further, (89) is a bevel gear which is located at one end side of the swing gear case (85) corresponding to the fixed arm (83) and is attached integrally to the lower end of the chain drive shaft (87). , (90) are also chain drive shafts (8
7) A drive gear fixedly installed at a mid-height position, and (91) is a chain drive shaft (8) at the other end of the swing gear case (85) corresponding to the swing arm (84).

It is meshed via 2) so as to be able to rotate equally in opposite directions. (93) is each idle gear (9
It is a spindle of 2), and needless to say, both chain drive shafts (8
7) in parallel with the swing gear case (85)
Installed on.

Reference numeral (94) is a universal joint shaft extending between the rocking gear case (85) and the work frame (B) in the front-rear direction, and a bevel gear (95) integrated and fitted to the front end of the universal joint shaft. ) Is the swing gear case (85)
Inside, a bevel gear (96) meshed with a bevel gear (89) attached to one of the chain drive shafts (87) and also integrally attached to the rear end of the universal joint shaft (94) is attached, The bevel gear (97), which is exposed in the transmission case (22) of the work frame (B) and is fitted in the middle of the crankshaft (29), is also transmission-coupled in a meshed state.

That is, the drive shaft (87) of the above-mentioned root-necked conveying chain (81) arranged in parallel as a pair of left and right is taken out from the engine (13) via the crank shaft (29), the universal joint shaft (94) and the like. The roots (b) of the parent strain (M1) clamped between the two root-holding transfer chains (81) are equally driven to rotate in opposite directions by a power, and the roots (b) are moved backward and upward. You can do it.

(98) is a chain drive shaft (8) exposed from the gear case (85) at the other end of the swing gear case (85) located corresponding to the swing arm (84).
It is a crank arm which is fitted and integrated with the lower end of 7), and the front end of the advancing / retreating rod (99) is connected to the front end of the crank arm via a pivot pin (100). 99) the rear end is the work frame (B)
To another by a separate pivot (101).

(102) is the above-mentioned root pinching and conveying chain (8)
1) A pair of left and right chain driven sprockets corresponding to the drive sprocket (88) of 1), which is attached to the chain driven shaft (103) which stands up integrally from the rear upper end position of the fixed arm (83) and the swing arm (84). On the other hand, both are fitted so as to freely rotate. The rear end portion of the root-holding and conveying chain (81) is wound around each driven sprocket (102) so that it can also circulate.

At this time, one of the chain driven shafts (103) penetrates the swing arm (84), and one end of the telescopic stay (104) supporting the swing arm (84) is attached to the lower end portion thereof. While being pivotally connected, the other end of the telescopic stay (104) is also attached to the work frame (B) via a pivot (105).

Reference numeral (106) is a compression coil spring wound around the expandable stay (104), and the swing arm (8)
4) One root-holding transport chain (81) pivotally supported by 4)
So as to approach the other root pinching and conveying chain (81) pivotally supported by the remaining fixed arm (83), the both sides of the pinching and conveying chain (81) are elastically biased from the lateral outside. The surface allows the root (b) of the parent strain (M1) to be clamped.

Therefore, by the power taken out and distributed from the engine (13), the root-holding conveyance chain (81).
When the drive shaft (87) is driven to rotate in a pair of left and right opposite directions, a crank arm (98) that rotates integrally with one chain drive shaft (87) corresponding to the swing arm (84), By the lever crank motion mechanism (I) composed of the forward / backward rod (99) and the like, the rocking gear case (85) makes the fitting surface of the bearing mouth tube (86) to the fixed arm (83) the vertical axis fulcrum (O- 19), a swinging action as shown in FIG. 19 is performed around it, and as a result, one of the pair of right and left root-holding conveyance chains (81) is pivotally supported by the swinging arm (84). Only the other of them, which is pivotally supported by the remaining fixed arm (83), quickly and reciprocally moves in a small amount in a longitudinal direction.

The stem (a) of the parent strain (M1) is pinched by the stem pinching / conveying belt (62) of the parent pinching / conveying mechanism (E), and the root (b) is also pinched and conveyed by the parent massaging and loosening conveying mechanism (G). In the process of carrying it upward and backward while sandwiching it with the chain (81), the root (b) can be rubbed by itself with the left hand as if it were rubbed into the right hand, so that the mud can be removed and efficiently dismantled. It is configured.

In order to achieve such an effect, the group of convexes (82) protruding from the wide clamping surface of the root clamping conveyance chain (81) receives the pressing biasing force of the compression coil spring (106). That also works organically.
The roots (b) of the parent strain (M1) must be the convex child (82) group.
Since the roots (b) are stabbed in the ground or crushed the roots (b), even if the roots (b) are combined with the adhesion of mud, the solid nodules can be surely dismantled no matter how violently they are entangled. is there.

Furthermore, the parent stock holding and conveying mechanism (E)
The stalk sandwiching conveyor belt (62) and the root sandwiching conveyor chain (81) of the parental massaging and loosening conveyor mechanism (G) are in an almost parallel rearward inclined installation state, while the seedling raising mechanism (D) preliminarily operates. The grass seedlings (M) that have been pulled up to the standing posture are continuously sandwiched and transported upward and rearward by the stem sandwiching transport belt (62) and the root sandwiching transport chain (81). Therefore, the parent strain (M1) is kept in a relationship of crossing them with a non-perpendicular constant angle (θ), and the root (b) is subjected to the above-mentioned loosening action under such a suspended state. ..

As a result, the above-mentioned root pinching and conveying chain (81)
The rubbing and loosening action of the root (b) is imparted to the root (b) of the parent strain (M1) as a comprehensive action of rolling along the circumferential direction of the root (b) and displacement along the vertical direction. In that sense, it can be dismantled efficiently in a short time.

(107) is the above-mentioned root pinching and conveying chain (8
In the case of the example shown in FIG. 1), the tight toner is interposed between the front and rear of the drive shaft (87) and the driven shaft (103), and the fixed arm (83) and the swing arm (84) respectively Although it is embodied as a sprocket that is loosely fitted to the intermediate shaft (108) that stands up integrally,
Of course, a leaf spring material or the like instead of the sprocket may be adopted to give a tension action to the root-holding and conveying chain (81).

In any case, as is apparent from FIG. 18, the left-right mutual spacing (W2) between the driven sprockets (102) supporting the root-holding and conveying chain (81) is agglomerated by the adhesion of mud. The size is narrower than the size of the root (b), and on the contrary, the drive sprocket (88)
The mutual right and left mutual spacing (W3) is differently changed as a size larger than the size of the root (b).

With such a configuration, the root introduction port (Q) of the parent strain (M1) defined between the left and right sides of the root-holding and conveying chain (81) is expanded into a substantially V-shaped plan view. Open it, smoothly accept the root (b) of the parent strain (M1) from here, and continue to gradually grasp from the left and right,
It can be transported to the upper rear.

Further, (L4) is the above-mentioned root pinching and conveying chain (8
The action length of 1) is shown, but its front end (action starting point) is compared with that of the above-mentioned stalk-holding conveyor belt (62).
It is at a position retracted rearward by a certain distance (X), and the stem (a) of the parent strain (M1) comes first, and then the parent pinching and conveying mechanism (E).
After being pinched by the stem pinching and conveying belt (62), the root (b) can be smoothly and surely pinched by the root pinching and conveying chain (81) of the parent massaging and loosening conveying mechanism (G).

On the other hand, similarly, the rear end portion (end point of action) of the root pinching and conveying chain (81) is the stem pinching and conveying belt (62).
The stem (a) of the parent strain (M1), which is in a corresponding position substantially matching that of the root (b) and whose roots (b) have been massaged and loosened, is then transferred to the stem receiving and pinching conveyor belt (7) of the carving and conveying mechanism (F).
2) By (73), under the suspended state, it can be conveyed upward to the seedling loading deck (19) of the vehicle body (A).

Furthermore, the height-cutting and aligning mechanism (H) of the sward seedling (M) is used when the subdivided stock (M2) after being carved by the carving and carrying mechanism (F) is nipped and carried to the upper rear side. In order to cut the tip end of the stem (a) in (M2) in an orderly manner, as shown in FIGS. 3 and 15, the upper stage stem receiving and sandwiching and conveying belt (72) is exposed from above the pair of right and left pedestals. ing.

That is, the height cutting and aligning mechanism (H) is embodied as a hair clipper (109), and its fixed receiving blade (1)
10) is attached to and integrated with the lower surface of the gear case (35) and receives the stem (a) of the child strain (M2).

Reference numeral (111) is a movable blade which slides on the fixed receiving blade (110) to act on the gear case (35).
It is connected to the lower end portion of the crankshaft (112) derived from the above through a pivot pin (113) and a receiving engagement elongated hole (114) so as to be reciprocally movable in the left-right direction.

The crankshaft (112) is parallel to the bypass transmission shaft (32) standing upright from the transmission case (22) of the work frame (B), and is located immediately in front of the bypass transmission shaft (32). is there. (115) is a large-sized hair clipper drive gear that is fitted and integrated in the gear case (35) at a mid-height position of the bypass transmission shaft (32), and (116) is a small-diameter driven gear that meshes therewith. It is a gear and is fitted and integrated in the middle of the crankshaft (112).

By the power of the engine (13) taken out from the bypass transmission shaft (32), the crankshaft (112)
Is driven to rotate at high speed, and the movable blade (11
1) reciprocates in the left-right direction, and the fixed receiving blade (11
0) the stem (a) of the child strain (M2) received by
It is designed to work quickly.

In this case, the fact that the height-cutting and aligning mechanism (H) is interposed in the high-speed transporting action process of the child strain (M2) carved from the parent strain (M1) also ensures that the stem (a) can be reliably treated. In addition, it can be said that it works effectively for quick trimming. (Y) suggests the trimmed height, but it is preferable to set the size to about 20 cm from the position of the rhizome. In addition, (117) is a child strain (M2)
Is a guide plate for smoothly guiding the root root (b) of the carcass to the seedling loading deck (19) of the vehicle body (A), the end point of action of the parent massaging and loosening transfer mechanism (G), and the loading deck (19).
It is fixedly installed between before and after.

When digging a grass sapling (M) using the digging work vehicle as described above, a pair of left and right sledges (38) are planted on the sapling ( It suffices to drive the car body (A) forward so as to divide into the stocks of M).

Then, a pair of left and right movable links (4
4) is reciprocated in the front-rear direction via the crankshaft (29) by the on-board engine (13) of the vehicle body (A), so that the digging cutter (39) of the seedling digging mechanism (C) is shown in FIG. As shown in Fig. 9, the mounting pivot pin (48) for the fixed link (47) at the upper end of the blade moves in an arc, and the blade (43) at the lower end of the blade moves forward and backward along the front-rear direction. , The blade (43) cuts off the root (b) of the grass seedling (M), leaving unnecessary hair roots in the ground, and the necessary part for planting seedlings is used as the parent strain (M1) to scoop from the ground It is excavated in a shape.

At this time, the sledge bush (38) is shown in FIGS.
As is apparent from the above, the two are in a parallel installation state in which a constant left-right mutual spacing (W1) is maintained, and a shovel-type rigid cutter blade (43) is interposed in the interior surrounded by this, and especially both Since the sledgehammer (38) also has a horizontal stable grounding surface (40) having a constant working length (L1), there is no risk of tilting the cutter (39) in an incorrect posture, and the blade (43) is used. (1) Keeping the digging depth (root cutting length) (Z) of grass seedlings (M) constant,
Can be trimmed. The stable ground contact surface (40) of the both sledges (38) works effectively as a reference member or regulating member for cutting the roots (b) of the parent strain (M1). There is no need to perform the laborious and heavy labor manual work of trimming after taking.

Further, when adjusting the digging depth (root cutting length) (Z) as the parent strain (M1), the pre-adjustment rod (50) is rotated to support it. The working length may be freely extended or shortened. When extended, the blade (43) of the excavation cutter (39), as seen from the solid line in FIG.
With reference to the stable ground plane (40) of 8), a shallow (short) set support state of the digging depth (cut length of the root) (Z1) is obtained.

On the contrary, when the working length of the adjusting rod (50) is shortened, as is clear from the chain line in FIG.
The blade (43) of the cutter (39) also has a deep (long) set of its digging depth (cut length of root) (Z2) based on the stable ground contact surface (40) of the sledge (38). Will be in the supported state. Therefore, in any case, in each set state, the cutter (3
By reciprocating 9) back and forth, the root (b)
Is a parent strain (M1) that has been trimmed to the desired length,
You can surely dig from the nursery.

Moreover, the seedling raising mechanism (D) faces the position just before the excavation cutter (39), and the raising claw (59) attached to the raising chain (58) allows
(A) The stem (a) of the grass seedling (M) is caused to act in advance in an orderly and upright posture, and the stem (a) is clamped by the stem clamping transport belt (62) of the parent strain clamping transport mechanism (E). However, since the root (b) is cut under the sandwiched state, the parent strain (M
In addition to being able to excavate 1) in a stable manner, even if a grass seedling (M) is lying down, the cutter (3) above
9) has a U-shape or L-shape in front view, but the cut hanger stem (42) of the cutter (39) may damage the stem (a) of the rush plant (M). Absent.

The stem (a) of the parent strain (M1) dug out of the nursery by the seedling digging mechanism (C) is pinched by the stem pinching / conveying belt (62) of the parent pinching / conveying mechanism (E). As it is, it is transported upward and rearward under the suspended state, and eventually the root (b) is also clamped by the root clamping transport chain (81) of the parent massaging and loosening transport mechanism (G).

A pair of right and left root-holding conveyance chains (81)
Under the sandwiching condition by the above, the group of convexes (82) protruding from the sandwiching surface of both chains (81) sticks to the root (b) of the parent strain (M1) or crushes the root (b). In addition, one of the root-holding conveyance chains (81) pivotally supported by the swing arm (84) has the vertical axis fulcrum (O-
O) through a swing gear case (85) that swings around, relative to the other root-holding conveyance chain (81) pivotally supported by a fixed arm (83), and reciprocates in the front-rear direction. Therefore, the root (b) is given a self-loosening action and a mud-removing action as shown in FIG. 21.

As a result, the roots (b) in the state of solid nodules intertwined with each other at high density, together with the adhesion of mud, are dismantled very efficiently and in a short time, and the parent strain (M
1) In order to smoothly and surely carry out the carving action from the stocks (M2) to the substock (M2), the effective preparation state is completed.
Note that the mud that has been dismantled by the loosening action is dropped and eliminated from the mud outlet (S) that opens between the fixed arm (83) and the swing arm (84) on the left and right sides to the nursery. ..

As soon as the parent strain (M1) reaches the action end points of the parent strain pinching and conveying mechanism (E) and the parent strain rubbing and loosening conveying mechanism (G), the root (b) of the parent strain (M1) is moved to the root pinching conveying chain. Contrary to being separated from the (81), the stems (a) are also divided into left and right pairs of an upper stage pedicle receiving and pinching conveying belt (72) and a lower pedestal receiving and joining pinching conveying belt (73) which also form a chopping and conveying mechanism (F). The inherited and pinched,
It will be transported to the upper rear while still in the suspended state.

In this case, the stalk receiving and sandwiching and conveying belts (72) (73) of the above-mentioned slicing and conveying mechanism (F) are faster than the stalk sandwiching and conveying belt (62) of the parent plant sandwiching and conveying mechanism (E). Since it is designed to rotate, the parent strain (M1) can be quickly and surely carved into the child strain (M2) as shown in FIG. The action is carried out by itself.

Further, during the high-speed transfer action process of the offspring stock (M2) by the both-stem receiving and sandwiching transfer belts (72) (73) of the division transfer mechanism (F), the hair clipper (H) of the height-cutting alignment mechanism (H) is used. 109) is also exposed, the movable blade (111) and the fixed receiving blade (110) quickly and quickly cut the tip of the stem (a) in the above-mentioned child strain (M2), and accurately cut and align it. Child stock (M2)
As a result, the seedlings are continuously loaded on the seedling loading deck (19) of the vehicle body (A).

In any case, if the operator is the vehicle (A)
When the lifter (25) is operated from above the driver's cab (20) of the vehicle, the rotating work frame (B) is moved to the column (1) of the vehicle body (A).
The seedling excavating mechanism (C) and the seedling raising mechanism (D), which are pivotally mounted around the fulcrum shaft (24) for assembling with respect to 2) and are integrated in the work frame (B),
The parent stock holding transport mechanism (E), the parent massaging and loosening transport mechanism (G), the sorting transport mechanism (F) from the parent stock (M1) to the child stock (M2), and the height-cutting alignment mechanism (H) are in a state of raising the entire front. Since it will be lifted to the ground, it is of course possible to run on a general road, get on and off the excavation work vehicle itself on the road transport vehicle, and get over the headland at the nursery without any problem.

In the illustrated embodiment, a series of mechanisms (C) and (D) from digging of the grass plant (M) to cutting and adjusting the height.
(E), (F), (G), and (H) are concentratedly mounted on the rotating work frame (B) of the vehicle body (A), but the parent stock (M1) is divided into the child stock (M2). Transport mechanism (F)
With regard to the height-cutting and aligning mechanism (H), by omitting these installations, the root (b) of the rush seedling (M) excavated from the nursery is also stalked by its parent massaging and loosening transport mechanism (G). It does not matter if it is only loosened and unraveled during the sandwiching and conveyance of (a).
