It can be disintegrated and shaken down, which is further improved by projecting upwards mud disintegrating protrusions (90) and (92) from the swinging middle and rear ends of the digging blade (68). Can be promoted,
There is no need to manually remove the mud, unravel the stock, or perform any other troublesome auxiliary work after excavation.

Further, since the pair of left and right weeding sleds (47) slide while touching the surface of the nursery bed, the depth (h1) of the stripping action of the width cutting blade (67) and the depth of the excavating blade (68) are reduced. The excavation depth (h2) is kept constant with respect to the sliding surface of the weeding sled (47), and as a result, the root (a) of the grass seedling (M) has a uniform cut length. There is no need to manually add subsequent trimming.

Further, according to the above configuration of the second invention, the first invention
In addition to being able to achieve the above-described effects of the present invention, the rush seedlings (M) dug from the nursery bed by the excavating blades (68) are continuously moved by the clamping frame (94) to the working frame (1).
1) Since it can be pinched and conveyed rearward and upward along the rear rising inclined surface and loaded on the upper surface of the track frame (10), it is extremely useful for workability and labor saving.

Reference numeral (85) denotes a rotating arm integrally fastened to the back surface of the digging blade (68) using the above-mentioned rotating pivot (78), and is substantially perpendicular to the digging blade (68) itself. To the left or right (in the example in the figure, the right side as viewed from the driver's cab).

A crank (86) is fixedly mounted on the other end of the power distribution shaft (62) corresponding to the rotating arm (85) so as to be able to rotate integrally with the power distribution shaft (62). The eccentric position 86) and the protruding tip of the rotating arm (85) are pivotally connected via a reciprocating rod (87) of a fixed length extending upward and inclined backward.
(88) is a pivot pin between the front lower end of the reciprocating rod (87) and the rotating arm (85), and (89) is a pivot pin between the rear upper end and the crank (86).

That is, when the crank (86) cranks around the horizontal axis of the power distribution shaft (62) by the power distribution shaft (62) receiving the driving force from the engine (12), the advancing and retreating rod ( The pivoting arm (85) pivotally connected to the crank (86) via the arm 87) reciprocates linearly in the vertical direction, and at the same time, the excavating blade (6).
8) swinging left and right with the pivot (78) as a fulcrum, cutting the root (a) of the rush seedling (parent strain) (M) vegetated on the nursery by its cutting edge (68a); This is to be excavated from the nursery.

The amplitude (w2) of the digging blade (68) is slightly wider than the constant width (w1) of the width cutting blade (67), and the width cutting blade (67) has a constant depth (h1) and width. (W
1) The root (a) of the rush seedling (parent strain) (M), which is buried in the ground, just below
The cutting is continued by the digging blade (68), and the rush seedling (parent strain) (M) is digged quickly and reliably from the nursery.

At this time, as the working machine progresses, the relatively hard topsoil of the nursery is cut by a width cutting blade (67) to a certain depth (h1), and the seedlings (M) are cut. The root (a) spreading over the adjacent rows is divided, and the digging blade (68) is continuously moved right and left so as to cross the position immediately below the fixed width (w1) where the streak is divided. Since it oscillates so as to draw an arc locus in the direction, there is no danger of embracing a lot of mud adhering to the root (a) above, so that the mud is shaken off and rush seedlings (M) are required. It can be dug to the minimum size, and the cut length of the root (a) becomes uniform.

If a preliminary rough decomposing protrusion (90) for mud is projected upward from the swinging midway of the excavating blade (68), the above-mentioned a. The mud adhering to the root (a) of the grass seedling (M) can be efficiently disintegrated, and the subsequent stock-sorting action can be promoted. (91) is a fastening nut for fixing the projection (90) from the back surface of the digging blade (68).

Further, as shown in a modified embodiment of FIGS. 18 to 20, the rotating arm (85) is partially extended rearward and upward, and the root (a) of the rush (M) is also extended from the extended portion. It can be said that it is even more effective if the protrusions (92) that shake off the mud adhering to (1) and roughly decompose are attached and fixed in an upwardly projecting state. Instead of protruding the protrusion (92) from the extension of the turning arm (85), the digging blade (68) itself is integrally extended rearward and upward from the turning pivot (78),
Of course, it may be good to project upward from the swinging rear end.

Reference numeral (93) denotes a gate-shaped or inverted L-shaped seedling receiving guide for front view, which is integrally erected from both weed sleds (47) at a position near the width cutting blade (67). Yes, the stalk (b) of the rush seedling (M) to be dug is once received, kept in a forwardly inclined posture substantially perpendicular to the conveying direction of a sandwiching and conveying belt described later, and the rushed young plant (M) after the digging Can be transported more stably by the sandwiching transport belt and in a correct forward tilting posture.

Next, the rush seedling holding and transporting mechanism (C) receives and pinches the stalks (b) of the rushed seedlings (M) dug as described above, and transports the stalks and seedlings upward and rearward. To do
As shown in FIGS. 21 to 25, it is composed of a pair of left and right endless nipping and conveying belts (94). (95) is the holding and conveying belt (9)
4) A pair of left and right belt driven pulleys around which
Reference numeral 6) denotes a pair of left and right driven pulley support shafts for the belt driven pulley (95).
The front base (31) in 1) is fixedly provided upright at the lower end of the front part.

(97) is the belt driven pulley (9)
A pair of left and right belt drive pulleys corresponding to (5), (9)
8) is a pair of left and right drive pulley shafts that handle this,
Numeral (99) denotes a horizontal transmission shaft which is laid so as to be orthogonal to the two drive pulley support shafts (98). As is apparent from FIG. 23, the drive pulley support shaft (98) and the bevel gear mechanism (100) ). (10
Reference numeral 1) denotes a pair of left and right bevel gear cases, which are attached and fixed in parallel to the first attachment seat plate (54) of the top base (52) forming the working frame (11) as described above.

Reference numeral (102) denotes a reduction gear case for receiving one end of the transmission shaft (99). The reduction gear case incorporates a reduction gear mechanism (103) for the nipping and conveying belt (94). (104) is an input gear shaft that forms the reduction gear mechanism (103), and (105) is also an intermediate idle gear shaft, both of which are parallel to the transmission shaft (99).

A fourth transmission pulley (106) is fixed to one end of the input gear shaft (104) exposed from the reduction gear case (102), and the fourth transmission pulley (106) is connected to the fourth transmission pulley (106). The distance between the power transmission shaft (62) and the fifth transmission pulley (107) installed in parallel on the power distribution shaft (62) is as follows:
As shown in FIGS. 5, 6, and 21, the power transmission connection is provided via the fourth transmission belt (108). Therefore, the engine (12)
By the power distributed from the nip conveyor belt (9)
4) is circulated and recirculated so as to pinch and transport the rush (M) rearward and upward.

(109) is the nipping and conveying belt (94)
A plurality of belt holding pulleys (tension pulleys) for applying a clamping force to the grass seedlings (M), and the entire front base (31) forming the working frame (11) is located at an intermediate height position, It is supported as a staggered distribution.

In this case, the holding / conveying belt (94) forming the holding / conveying mechanism (C) includes a reduction gear mechanism (103).
, The work implement is driven to rotate a certain degree slower than the traveling speed of the work machine. To that extent,
About 50 to 80% of the traveling speed of the work machine is suitable.

If the setting is made in this manner, the stalk (b) of the rush seedling (M) planted on the nursery is in a state in which the holding and conveying belt (94) is inclined upward after a certain angle. As the work machine advances, the above-mentioned seedling receiving guide (93)
FIG. 35,
As shown at 36, the rush is introduced to the starting point (XX) of the conveying operation of the nip conveying belt (94), starts to be partially pinched there, and is not yet pinched at the root of the stem (b). The root (a) of the seedling (M) will begin to be cut by the excavating blade (68).

With the further advance of the working machine, the excavating blade (68) excavates a predetermined distance (L), and by the time the excavation of one plant of the grass seedling (M) is completed, the work is completed. The stalk (b) is conveyed backward and upward by a fixed distance (Z) shorter or shorter than the digging advance distance (L) of the digging blade (68) by the sandwiching / conveying belt (94) slower than the traveling speed of the machine. Then, even the root of the stem (b) is introduced to the transfer operation start point (XX) of the sandwiching transfer belt (94),
37 and 38, the sheet is conveyed stably upward and rearward in the completely sandwiched state as shown in FIGS.

In other words, by adopting a configuration in which the nipping and conveying belt (94) is driven to run slowly at a lower speed than the traveling speed of the working machine (the digging advance speed of the digging blade), In the digging process, the stem (b) is given a downward pushing biasing force, and can be smoothly turned to a forwardly inclined posture substantially orthogonal to the conveying direction of the sandwiching conveying belt (94). is there.

The stalk (b) of the rushed seedling (M)
In the process of slowly and rearwardly conveying the mud elastically and firmly, the mud adhering to the root (a) is upwardly projected from the digging blade (68) that swings at a high speed. It is disrupted by the offspring (90) and (92), so that the effect of stock splitting on the offspring (m) by the below-described stock splitting mechanism (D) can be promoted.

In addition, it has been described above that the excavating blade (68) extends in the upwardly bent shape. However, the excavating blade (68) has the root (a) of the rush (M) which is excavated and pinched and conveyed. 37, a certain clearance space (O) is secured between the digging blade (68) and the upper surface of the digging blade (68). Just as the root (a) is rubbed, the nipping and conveying belt (94) does not interfere or resist the conveyance of the rush (M).

The purpose of setting the traveling speed of the holding and conveying belt (94) to be somewhat lower than the traveling speed of the working machine (the digging advance speed of the digging blade) is to hold the grass seedling (M). The present invention aims at turning the conveyor belt (94) to a forwardly inclined posture substantially perpendicular to the conveying direction so as to be able to stably convey the conveying belt (94).
