Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for blowing air to uncut rushes in a rush harvester.

<Prior Art> The present applicant has proposed a rush harvesting machine that is devised to assist the weeding and raising action by blowing or force-feeding wind toward the rushes being planted from the field. , previously proposed patent application No. 1-200003.

In this case, the air discharge nozzle (63) that will vertically extend from now on is fixedly installed on the weeding sled plate (39) that extends forward from the machine body (A), while the driver's seat of the machine body (A) ( B) is equipped with a blower (66) for generating high-pressure air, and a flexible air supply pipe (68) L is installed between the nozzle (63) and the blower (66) in front and back.
There is a continuous connection from here.

<Problem to be solved by the invention> However, according to the results of subsequent intensive studies, in the case of the above prior invention, the blower (66) is located in the driver's seat (B) located at the rear of the aircraft (A). Since the transmission belt (72) between the blower (66) and the engine (13) and the air supply pipe (68) extend considerably long, the transmission system and There is a problem that the piping system becomes complicated and is likely to cause loss of operation.

In particular, in order to eliminate the air pressure loss, it is necessary to make the blower (66) larger and faster, due to the limited space of the step (22) in the driver's seat (B). , the blower (66) will protrude greatly from the aircraft (A>), and the aircraft (A>
) hinders miniaturization and weight reduction.

Also, the blower (66) is installed on the step (22) of the driver's seat (B).
), the air discharge nozzle (63) is in a fixed state, but the air discharge nozzle (63) is supported by the work frame (12) which moves up and down.
]2) When the aircraft (A>) is lifted up to a tilted state with respect to the truck frame (11), the air supply pipe (68) is loosened, and the stability of the attached state is affected. Not only does this have an adverse effect, but it is also difficult to reliably stop the air from being ejected from the nozzle (63).

<Means for Solving the Problems> The present invention is intended to improve the above-mentioned problems, and for this purpose, the fuselage is constructed with a track frame, and the front part thereof is pivoted so that it can be lifted forward by a horizontal shaft. A weeding mechanism and a pulling mechanism for uncut rushes are erected on a horizontal weeding board that is formed from a supportingly connected work frame and extends forward along the ground from the lateral end of the uncut side of the work frame. In addition to establishing
The output shaft of the engine installed on the above truck frame,
Similarly, when installed at a position a certain distance behind the horizontal shaft, the front and rear of the intermediate shaft is connected by a power transmission belt, while the horizontally suspended power distribution shaft and the intermediate shaft are installed on the work frame. The front and back of the shaft are connected for transmission by another transmission belt that is longer than the transmission belt, and the power of the engine distributed from the power distribution shaft drives the weeding mechanism and the pulling mechanism. Determined rush yield [
In No. 41131, a blower fan that is integrally rotated by the distribution shaft and a speed increasing gear mechanism for the blower fan are attached to the uncut side shaft end of the power distribution shaft; The main feature is that an air jet nozzle that opens toward the grass during weeding is attached to the section, and the nozzle and the blower fan are connected in communication through an air discharge pipe whose front part is slanted. That is.

Effect> According to the above configuration, the blower fan (67) is connected to the airframe (
The work frame (12) forming the front part of the work frame (10) is supported by its power distribution shaft (40), and is rotationally driven by the power of the engine (16) extracted from the work frame (12). The blower fan (67)
The blower fan (67
) is not only significantly simplified, but also the air discharge pipe (77) that communicates and connects it with the air discharge nozzle (78) is also extremely short, even if a rigid one is adopted. In relation to the lifting operation in the work frame (12), there will be no cutting failure or adverse effects, and on the contrary, the air jet nozzle (78) from the blower fan (67)
Air can be pumped without any loss of heat.

Further, a blower fan (6) is mounted on the power distribution shaft (40).
7), as well as the platform speed gear mechanism (71) of the fan (67).
) is also assembled, which allows the blower fan (67) to rotate at high speed on its own, allowing extremely powerful air to be jetted from the air jetting nozzle (78) onto the uncut rushes. In this sense, it is possible to make the blower fan (67) smaller and flatter, which in turn has the effect of suppressing the amount of protrusion of the blower fan (67) in the lateral direction from the work frame (12).

<Example> Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated example. Figures 1 to 4 show the entire rush self-loading riding type harvesting machine suitable for two-row cutting. (10) is a general term for the aircraft, consisting of a fixed track frame (11) and a work frame (12) that can be raised and lowered to form the front part.

In other words, the work frame (12) includes a rush weeding mechanism (A) and a raising mechanism (B), which will be described later, and a rush conveyance mechanism (
C), supports a series of working mechanisms consisting of a stock-head reaping mechanism (D), a waste pick-up and sorting mechanism (E), a stock-head side convergence and conveyance mechanism (F), and a stock-head binding machine 1 (C). The rear base end of the frame is pivotally connected to both left and right end portions of the truck frame (11) via a horizontal horizontal shaft (13), and the frame is generally horizontally shaped in plan view. A hydraulic cylinder (14) for raising and lowering the work frame is inserted between the front and rear of both frames (11, 12).

Therefore, by extending the piston rod (15) of the hydraulic cylinder (14) forward from above the driver's cab, which will be described later, the work frame (12) can be moved to the horizontal axis (13) as shown in FIG. It is possible to raise the truck frame (If) to an upwardly tilted state while using the truck frame (If) as a rotational fulcrum. As described above, the work frame (12) has a generally horizontal shape when viewed from above, and has a shape in which the biased position on the left side (uncut side) extends forward for a long time.

(16) is the engine mounted in the front position of the truck frame (11), and (17) is the same frame (11).
It is a driving transmission installed at the rear of the
It is transmission connected to the output shaft (21) of the engine (16). In that case, the intermediate shaft (18) is the work frame (1).
It is horizontally mounted at a position offset backward by a certain distance (d) from the horizontal axis (13) which forms the rotational fulcrum in 2).

In addition, the output shaft (21) and intermediate shaft (18) of the engine (I6)
) and other pulleys are omitted from illustration numerals.

(22) is a pair of left and right running crawlers 2 that are rotated by the power taken out from the transmission (17).
(23) is a rush binding bed located at the front of the truck frame (11) and also covers the entire top surface of the engine (I6); (24) is the rush binding bed (23); , is the main deck for Igusa Higashi loading that covers the entire upper surface of the transmission (17), intermediate shaft (18), etc., and as suggested from the side view in Figure 1, it is preferably made of metal plate material with an abbreviated letter. In addition to being curved in a mold, there is a certain height difference (h
) are also given. The main deck (24), which has a concave groove shape, can accommodate as many rush bundles (M) as possible.

(25) is the main deck (
The driver's cab is integrally extended rearward from the operator's control box (26) and the seat (27).
) and a roof (28) for sun protection.

Therefore, while riding on the driver's cab (25), the operator can visually check the 8I load of the Rush Bunch (M) on the main deck (24) located immediately before it, and extend the control to this. It is also easy to correct irregularities and stability in the loading state.

- (29) is a vertical axis extending perpendicularly to the horizontal axis (13) along both sides (already cut (III) ends) of the continuous main deck (24) and cab (25). (30), Igusa Higashi 17I was pivoted in a freely undulating manner.
It is a sub-deck for carrying T-mounts, and is preferably made of metal rods and integrated into a frame in an abbreviated shape when viewed from the front. The inside of the sub-deck (29) is open to communicate with the inside of the main deck (24), and as is clear from Figure 6.7.19, inside the main deck (24) there are Contrary to the fact that the grass bundle (M) is placed in an extended state along the left and right direction of the fuselage (10), this sub-deck (
Inside 29), rush bundles (M) are laid down so as to extend along the longitudinal direction of the fuselage (10).

(31) is a rotating piece that integrally extends from the framework material at the rear position of the sub-deck (29); (32)
is a hydraulic cylinder for raising and lowering the sub-deck attached to the lower surface of the cab (25) so as to correspond to the rotating piece (31), and is pivotally connected to the rotating piece (31). By moving the piston rod (33) that has been attached to the driver's seat back and forth in the left and right directions from above the driver's cab (25), the sub-deck (29) is moved about 90 degrees around the fulcrum of the vertical axis (30).
It can be raised and lowered by a certain angle range (α) of degrees.

As shown in Figure 6, it is a bunch of rushes (
M) can be stably loaded, and the rush bundle (M) can be easily unloaded to the right side (already cut side) of the machine body (10) by flipping it down as shown in Figure 7. can do. By changing the undulating rotation angle (α), the loading amount of rush bundles (M) can also be adjusted.

Hydraulic cylinder for raising and lowering the sub-deck (29)
(32) and the hydraulic cylinder (14) for raising and lowering the working frame (12) are as extracted in Fig. 4.8, and the hydraulic control valve (34)
Needless to say, the levers (35) are operated individually from the cab (25). (36) is a hydraulic pump that pumps hydraulic oil to the two types of hydraulic cylinders (14) (32>), and is operated by the engine (16).

(37) is also two types of hydraulic cylinders (14) (3
This oil storage tank is common to 2), and is fixedly installed on the truck frame (11) like the pump (36).

(38) and (39) indicate the oil feed pipes, respectively.

(40) is a series of working mechanisms (A) to (G) mentioned earlier.
This is a primary power distribution shaft for inputting working power to the work frame (12), and is supported at a position biased to the left side (uncut side) of the work frame (12). This primary power distribution shaft (40)
．． As is clear from the side view in Figure 5, the front view in Figure 9, and the plan view in Figure 10, the horizontal axis (13) and the intermediate axis (
18), and its horizontal axis (
13) Located in a more anterior position.

The primary power distribution shaft (40) and the intermediate shaft (1)
The front and rear of the engine (8) are electrically connected via a relatively long endless third transmission belt (41), and therefore the single engine (1) mounted on the truck frame (II)
6), the primary power distribution shaft (40) is rotationally driven. In that case, as suggested from Fig. 1.5, the pulley (42
> is dimensioned to have a considerably larger diameter than the corresponding pulley (not shown) on the intermediate shaft (18).

(43) is inside (right side) of the above primary power distribution shaft (40)
The first bevel gear mechanism is integrated into the shaft end (this is indicated by a gear case in the figure, and the same applies to the second to eighth bevel gear mechanisms described later).
From now on, as shown in FIGS. 9 to 11, the transmission shaft (44) will stand up toward the upper clamping and conveying mechanism (C),
Focusing conveyance mechanism (F) and bundling mechanism (G) also on the right side
The transmission shaft (45) horizontally mounted towards the front is partially extended.

Similarly, a working transmission (46) is also interposed at an intermediate position of the primary power distribution shaft (40), and a power transmission shaft ( 47), the weeding mechanism (A), the pulling mechanism (B), and the reaping machine +! which are sent to the opposite left position!
The power transmission shaft (48) used for three purposes (D) is horizontally suspended parallel to the primary power distribution shaft (40) itself.

In other words, the work frame (12) forming the front part of the aircraft (10)
) A series of working mechanisms (A
) to (G) are powered by the engine (16) mounted on the truck frame (11), which also forms the rear of the aircraft (■0).
They are all driven via the primary power distribution shaft (40).

At this time, the tension roller (49) that contacts the third power transmission belt (41) from below is mounted on a shaft on the fixed track frame (11) side, and the tension roller (49) contacts the third power transmission belt (41) from below.
12) is lifted around the fulcrum of its horizontal axis (13), the third power transmission belt (41) is lifted from the tension roller (49) based on the existence of the above-mentioned constant distance till (d). As shown in Figure 5, it floats and relaxes, and its transmission function is automatically released. Therefore, it is possible to effectively prevent unexpected personal accidents while not working.

Regarding the above series of working mechanisms (A) to (G), I will first explain the rush pulling mechanism (B), which is biased toward the front end position on the left side (uncut side) of the working frame (12). , a pair of inner and outer (right and left) lifting chain cases (50) (51) that are arranged in parallel with an upward slope at a certain angle;
Endless lifting chees 7 (52) (53) are housed in the interior so as to be able to circulate freely in the vertical direction, and each of the chees 7 (52) (53) has a large number of undulations at regular intervals. Freely pivoted raising claws (54) (55
), the raising claws (54) and (55) protrude from the chain case (50) and (51) during the upward movement, and the rushes are raised as if combing them by themselves. .

(S) is a rush passage that is opened between the opposing chain cases (50) and (51). By arranging the inner chain cases (50) in an open position, they form a substantially right-angled triangle when viewed from the front. However, it is also possible, of course, to divide the chain cases (50) and (51) into a raised passageway (S) opening in a V-shape when viewed from the front by opening the legs equally.

And in any case, the inner chain case (50)
has a lifting check 7 (52
) is built in so that it rotates, while a hoisting chain 7 (53) that rotates only in its lower half is housed inside the outer chain case (51). The lifting pawls (54) and (55) of the chains (52) and (53) are arranged in a staggered manner and rotate upward in an orderly manner.

In other words, the pulling passage (S), which opens in a triangular or V-shape when viewed from the front, is arranged alternately from the left and right directions, where the stock cutting action @ (W) by the clipper blade of the cutting mechanism (D) is the bottom, so to speak. Drawing centering nails (54
) (55) is positioned at the midway height of both chain cases (50) and (51). Furthermore, the width of the cutting action (W) at the bottom corresponds to two rows of rushes, and while the two rows of rushes are pulled up all at once, they can eventually join together from the tip side. It has become.

(56) is a secondary power distribution shaft that is installed at a rear position of the outer lifting chain case (51) in an inclined state that is substantially parallel to the outer lifting chain case (51), and its lower end is the above-mentioned weeding mechanism (A). ), the pulling mechanism (B), and the reaping mechanism (D).
The second umbrella wheel mechanism (57) goes to the transmission shaft (48) which is also used for
A transmission shaft (58
), the clipper blade (5) forms the reaping mechanism (D).
9) is designed to be reciprocated in a straight line 22 times in the left and right direction.

The clipper blade (59) is supported at the lower end of the working frame (12) so as to cross behind the pulling path (S), and the cutting action @ (W) of the stock base is thereby performed. As mentioned above, it is equivalent to two rows of rushes.

On the other hand, at the upper end of the secondary power distribution shaft (56), there is a third bevel gear mechanism (60) and a fourth bevel gear mechanism (61) located on the inner right side of the third bevel gear mechanism (60), as shown in FIG. Detour transmission shaft (62
) are installed in parallel via the fourth bevel gear mechanism (
61) A transmission shaft (63) projecting forward causes the lifting check 7 (52) inside the inner chenoke case (50) to be rotationally driven.

(64) is the fifth bevel gear mechanism that is also assembled at the mid-height position of the secondary power distribution shaft (56), and from now on, the transmission shaft (65) that also projects forward is connected to the outer Cheno case ( The lifting chino (53) inside 51) is rotated. It goes without saying that the inner and outer pairs of the raising checks 7 (52) and (53) rotate synchronously in the above-mentioned alternating and intricate state.

(66) is the lifting claw (54) of the lifting mechanism (B).
) (55) This is a blower device that assists the raising action of rushes and quickly straightens the rushes to the tip side, and the rotational driving force of the blower fan (67) is
The outer (left side) shaft of the next power distribution shaft (40): It is taken out from the tA section.

That is, in Fig. 11, which is extracted and enlarged, (68)
is the hanging pulley (42) of the third power transmission belt (41).
) is a transmission pawl plate that is fitted in such a way that it can be freely inserted and removed from the lateral outside and rotated integrally with the transmission pawl plate, and is provided with a support shaft (69) that protrudes laterally from the center thereof. (
70) is the rotational support shaft of the blower fan (67) facing this, and the blower fan (67) is connected between the inner and outer sides.
7) speed increasing gear ll' [(71) is inserted and installed. The speed-increasing gear mechanism (71) allows the blower fan (67) to generate high-speed, high-intensity wind power while minimizing its size and weight.

C72) is the gear case (73) of the speed increasing gear mechanism (71)
pedestal for installing on the work frame (work 2), (74
) is a fan case that is fixedly integrated into the case (73), (75) is a mesh-type air inlet opening in the center, and a safety cover (76) is attached from the side outside.
covered by. (77) is a fan case (7
4) is an air discharge pipe connected to No. 1.5.
As is clear from the figure, the air jet nozzle (78) extends along the left side end of the work frame (12) and is inclined at a certain angle, and the air jet nozzle (78) is located at the lower front end of the work frame (12).
) is in an open state pointing toward the rush to be raised from a position immediately in front of the outer raising chain case (51>).

In other words, the air jet nozzle (
78) is fixedly supported on the outer sled plate of the weeding machine +1 (A), which will be described later, and is oriented almost directly above when viewed from the side as shown in Figure 12, and at the same time when viewed from the front. Sometimes, as shown in Figure 13, the inner drawer cenocase (50)
It opens diagonally upward, intersecting the

Therefore, the rush is attached to the lifting claw (54) of the lifting mechanism (B).
Just before the bow is applied to (55), a strong wind is generated from the follower fan (67), and the air jet quickly straightens the air to a vertical state, and also ensures that the entanglement on the tip side is separated. Furthermore, even though it is possible to pull up just under two rushes, there is no risk of damaging the stem culm.

(79) is a blowing guide plate that receives and stops the air jet from the air jet nozzle (7th) and guides it upward reflectively, and extends along and roughly around the inner lifting cenocase (50). The splint is fixed to the lower half as a constant-height protrusion facing forward. Therefore, the 12th.
As suggested from Figure 13, the air jet that hits this is refracted upward and used to raise the rushes without any loss, significantly increasing the efficiency of the action. be.

Next, the rush weeding mechanism (A) is used to move the grass from the field to the rushes to be planted prior to the raising action by the raising claws (54) and (55) of the above-mentioned raising mechanism (B). Therefore, it is installed at the frontmost position on the left side (uncut side) of the work frame (work 2).

That is, (80) and (81) are the parallel inner and outer sides (right and left) that define the stock cutting action width (W>) of the clipper blade (59).
A pair of grass cutting boards, both of which are work frames (12)
It is attached to and integrated with the grass sled board inside it (
80) has the lower end portion of the above-mentioned inner lifting cenocase (50) fixedly supported, and the outer grass cutting sled plate (81) also has the lower end portion of the outer lifting cenocase (51) fixedly supported.

Moreover, the plates (80) and (81) on both sides extend forward by a certain distance 11i (ff) from the chain cases (50 and 51), as if along the ground.
At the front end of the outer grass dividing sled plate (8I) is a grass dividing arrow (82).
is fixedly installed, while a rush introducing guide rod (83) is bent up from the front end of the inner side grass dividing plate (80). (84) is a revolving grass divider that is raised from the front end of the outer grass divider plate (81) and is erected in a sloped state at a gentler angle than the chain cases (50) and (51). rIi, it is curved from resin or other flexible material into an overall circular arc shape when viewed from the side. Its curvature gives it a constant amplitude of orbital motion.

The lower front end of the revolving branch rod (84) is the branch arrow (
The upper rear end of the oscillating transmission shaft (85) is fitted into the front end bearing cylinder of the oscillating transmission shaft (85) so as not to rotate. )
passes through the upper part of the outer chain case (5I) and extends rearward and upward. (86) is a sixth bevel gear mechanism installed between the upper and lower sides of the third bevel gear mechanism (60) and the fifth bevel gear mechanism (64) in the secondary power distribution shaft (56), The secondary power distribution shaft (56) and the swing transmission shaft (85) are transmission-connected via this.

Therefore, the revolving weeding rod (84) is then driven by the power of the engine (16) introduced from above to make a revolving movement in order to weed the rushes, and the rushes lying down in the field are removed by this movement. cause At that time, as described above, the blower device (6
Since the air jet nozzle (78) of No. 6> is also faced, a synergistic weeding and raising action with the revolving weeding rod (84) is imparted to the rushes.

Further, before the rush is raised by the raising claws (54) and (55), the rush is also subjected to a sliding action by water. (87) (88) are a pair of inner and outer (right and left) water jet nozzles that form the lubricating device (89), and include the above-mentioned lifting chain case (50) (51) and the weeding sled plate (80) (81). It corresponds to The pair of water jet nozzles (87) and (88) are raised and positioned just in front of the chain cases (50 and 51), and are fixedly supported by the grass cutting sled plates (80 and 81), respectively. .

In that case, the outer water jet nozzle (88) faces the position just before the air jet nozzle (78), but in any case, the rain water jet nozzle (87) (88)
As shown in the figure, they are oriented almost directly above when viewed from the side, and when viewed from the front, they appear parallel to each other forming a H-shape.
It opens diagonally upward.

A stream of water is forced from the rainwater spouting nozzles (87) (88) towards the grass, wetting the stem culm in a state of condensation and acting as a lubricant to eliminate the cause of damage. The purpose is to have a water jet (water jet) also participate in raising the rushes.

(90) is a water storage tank removably installed in the cab (25) of the aircraft (lO), and this and both jet nozzles (87) and (88) are connected to a water supply pipe (91) such as a flexible hose. ) are connected in communication. As shown in Figures 1 to 3, the water supply pipe (91) extends from the track frame (11) IJ to the work frame (12) along the left edge of the aircraft (lO), and in the middle A pair of weeding sled plates (
80) (81) and rainwater spout nozzle (87) (8
8) in a branched manner. Similarly, (93) is a stay protruded downward from the front end of the work frame (12) in order to smoothly branch piping to the inner side grass dividing plate (80).

(94) (95) (96) are also water pipes (91
) are installed in the middle of each of the solenoid valves, pumps, and their drive motors, and as is clear from the control circuit in Figure 16, the levers are operated by the operator from the driver's cab (25). It has become.

In other words, when applying the lubricating effect of water to rushes, the electromagnetic valve (94) is in an open state, and the pump (94) is in an open state.
5), the main switch (97) is turned on, and a series of working MM structures (A
) to (G), the clutch lever (98) is operated to turn on the interlocking switch (99) for the working structures 18 (A) to (G). and pump (95) the water in the tank (9o).
), the rainwater is pumped to the rainwater spouting nozzles (87) and (88).

If such a filJ control circuit is adopted, it is possible to harvest rushes without using the lubricating device (89) by keeping the main switch (97) in the OFF state in advance. become.

In that case, in order to be able to replace the water storage tank (90) itself, the water supply pipe (91) is removably inserted into the tank (90), and the water intake valve <100 is shown in the figure.
), but it is also possible to connect and integrate the water supply pipe (9) and the water storage tank (90) in advance so that only water can be replenished into the tank (90). good. The electromagnetic pulp (94) is used to prevent natural suction of water due to siphon action. (101) indicates a battery.

The rushes that have been subjected to the weeding action and the raising action as described above pass through the raising passage (S) in a merging state, and are transferred to the tip-side pinching and conveying mechanism (C) behind it as shown in Fig. 17. The clipper blade (59) of the stock head reaping Wi (D>
It is cut by.

Then, the harvested rush is lifted up and transported to the rear of the machine (10) with the tip of the rush being clamped by the clamping and transporting mechanism (C).
C) is constructed so as to properly face the mid-height position of the lifting passageway (S) from behind and extend along the longitudinal direction of the fuselage (10). The intermediate height position at which it should be constructed should be at least the above-mentioned lifting claw (54) (55
) is preferably positioned at the rising action limit (P).

That is, (102) and (103) are the clamping and conveying mechanism (C
This belt is a pair of endless double-row type rush gripping belts (inside and outside (right and left)) forming a shape of 38 cm (right and left), and as is clear from FIGS. 21 to 23, rushes are held elastically by the close contact of their back-to-back surfaces.

In that case, the outer clamping heel (103) is suspended by a pair of front and rear pulleys (104) (105), and is rotated by the power introduced from the drive pulley spindle (106) on the rear side. It is now possible to do so. The drive pulley support shaft (10) of the outer clamping belt (103)
6) is transmission connected to the transmission shaft (44) standing up from the above-mentioned primary power distribution shaft (40) via the reduction gear mechanism (107).

(108) is the remaining front driven pulley support shaft, (109)
is the belt tensioner of the outer clamping heel (103), and the square bar yoke (110) and its sheath cylinder rail (111)
), and a compression coil batt (112) is also enclosed inside. And front and back like this - sword pulley (10111) (106)
The belt tensioner (IO9) therebetween is mounted and supported by a head frame (113) that has a vertical U-shape in cross section and extends in the front and back direction.

In addition, the inner wall surface of the head frame (113) faces so as to cover the position next to v1 of the Igusa curve guiding belt and retraction belt, which will be described later, and the holding belt (102) (1
A long sloping guiding skirt (114) is used to direct the rushes hanging from the pipe (114) inward.

On the other hand, the inner clamping belt (102) parallel to the outer clamping belt (1o3) also has a pair of front and rear pulleys (115).
(116), but a plurality of intermediate pulleys (], 17) are also pivotally supported between the front and back of the pulleys, and this allows the inner clamping heel l-(102) to extend from the inner side. Under the force, it is curved into an arcuate shape that comes into close contact with the outer clamping belt (103).

In other words, when the back-to-back surfaces of both clamping plates (102) and (103) are viewed from above as shown in FIG. 21, they form a smooth outwardly convex curved surface as a whole.

Therefore, the stem side of the rush whose tip side is being pinched and transported is
4 inward of the aircraft (1o) as described below! While moving Ii, the overall arcuate shape as seen from the front makes it possible to easily change the orientation to the sideways posture.

(118) and (119) are the front driven pulley support shaft and the rear drive pulley support shaft of the inner clamping belt (102), and the drive pulley support m (119) is connected to the fourth bevel gear mechanism (6th gear). ) to the 7th bevel gear machine! (12
The transmission shaft (121) extends downward through a reduction gear mechanism (122).

The outer clamping belt (103) connects the primary power distribution shaft (4o) and the transmission shaft (44) as described above based on Figure 9.1o.
The inner clamping belt (102) is rotatably driven by the input from below via the secondary power distribution shaft (5).
6>, the detour transmission shaft (62), and the transmission shaft (121) from above, the outer clamping belt (
It is designed to be rotated in a direction in which rushes are conveyed, which is opposite to IO2).

The back-to-back surfaces of the above-mentioned clamping heel) (102) and (103) are provided with a certain interlocking step (1) as suggested by Fig. 23, which prevents the rushes from falling off or misaligning. It is possible to reliably hold and convey this without causing any damage. Moreover, the back-to-back surfaces are non-vertical surfaces as a whole, and when viewed from the front and back direction of the aircraft (10), the inner clamping belt (102) is positioned slightly higher and upward than the outer clamping belt (103). They are arranged side by side in an inclined alignment state in which they are piled up so that the deviation changes.

In other words, the back-to-back surfaces of both rush gripping bells (102) and (103) are the front and rear drive pulley support shafts (10
6) (119) and driven pulley support shaft (108)
(118), the axes (Y-Y) of the pulley spindles (106) (108) (118) (119) are all parallel to the virtual vertical line ( In other words, it stands in an inclined posture with an external slope that intersects ○−○) by a certain angle (β).

As a result, as shown in Fig. 24, the tip side of the rushes held between the back-to-back surfaces will be automatically swung inward of the machine body (1o) after the rush is harvested. The child is kept in the sideways biased state. However, both rushes are held in place) (102) (1
The back-to-back surfaces of 03) are taken as the overall vertical plane,
Of course, the left and right pairs may be arranged in parallel at the same installation height.

(123) is a rush-curved guiding belt parallel to the lower stage of the inner clamping belt (102), which is also being searched by the front and rear pair of pulleys (124) and (125). , rear drive pulley support shaft (126
) is connected to the drive pulley support shaft (119) of the inner clamping bell (102) so that it can rotate integrally from below as shown in Fig. 123) is the inner clamping bell I-(
1, 02) in the same direction and at the same speed.

Moreover, the drive pulley support shaft (126) of the curve guiding bell (123) has an axis <2 -2) is bent inward by a certain angle (γ) as shown in FIG. ) (103), which is almost perpendicular to the rush hanging from the back-to-back surfaces, so that it can properly follow the conveying action to the rear without giving any resistance to the rush. (127) is the curved guide bell) (123) is a resilient membrane that is made of a sponge and other materials that are glued and integrated, and prevents rushes from getting scratched and slipping.

(128) is the front driven pulley support shaft of the curve guiding belt (123), which is different from the rear drive pulley support shaft (126) described above, and the pulley (118) of the inner clamping belt (102). (119) as an array state parallel to its inner clamping bell) (102
) and the curved guiding bell (123) are projected downward from a belt tensioner (129) interposed between the upper and lower sides. As is clear from Figures 22 and 23, the curve guiding belt (123) has a pair of front and rear pulleys (124
) (125), it is twisted in a gradually twisted state as it goes to the rear, and the length of its action (×1) corresponds almost to the latter half of the inner clamping bell (102). do.

The belt tensioner (
], 29) is a pair of front and rear sheath tube rails (130) (13
1), and a square bar yoke (1) that telescopically connects them to each other.
32), since compression coil springs (133) are also enclosed inside both rails (130) and (131), they are in a normal state of being expanded as a whole.

The front driven pulley support shaft (128) of the curve guiding bell (1, 23) is rotatably supported by the yoke (132) located in the middle of the belt tensioner (129). A tension acting force naturally acts on the curve guiding belt (123). The rear rail (
131) is a curved induction bell by the stay (134>)
It is fixedly supported by welding or the like to the bearing cylinder portion of the rear drive pulley (126) at (123).

(135) faces between the upper and lower sides of the belt tensioner (129) and the curved guide bell (123), and is paralleled with the working length (x 2) corresponding to approximately the front half of the inner 1 clamping belt (102). It is a rush retraction belt equipped with a plurality of overhanging lugs (136) capable of catching rushes.

And this is a pair of front and rear pulleys (137) (13
8), but the pulley on the rear side (1
38) is fitted to the front driven pulley spindle (128) of the above-mentioned curve guiding belt (123) so as to be able to rotate integrally, so that the curve guiding belt (123) moves in the same direction and at the same speed. It is designed to be driven by rotation. The front pulley (137) of the retraction belt (135) is connected to the belt tensioner (129).
The front rail (130) is pivotally supported for free rotation.

In other words, the retraction belt (135) is
) to the back-to-back surfaces of both clamping belts (102) and (103), as a device that reliably draws and introduces rushes.
In addition, the curved guiding bell (123) curves the rush inward into the machine body (10) into a smooth arc while the rush is being held and conveyed rearward by the holding belts (102) (103). As shown in Figs. 21 to 23, the clamping belt (102) (
103) and the pre-assembly is made into a unit.

As for the rush guiding effect by the curved guiding bell (123), the guiding skirt (114) of the head frame (113) also participates in this as described above, so -
They will definitely be distant relatives in a stable manner.

In that case, a pair of inner and outer rush clamping bells) (102) (
103) is its pulley support shaft (106) (108) (118) as suggested by the chain line in Fig. 22.24.
) The installation height can be adjusted by sliding in the vertical direction along (119). It can also be used by changing the gripping position on the tip side of the rush.

At the lower position of the rush clamping belts (102) and (103) that form the clamping conveyance 18Fjt (C), there is a waste sorting machine +! (E) are installed in an array extending horizontally along the front of the fuselage (10), and the base side of rushes hanging from the above-mentioned clamping bells (102) and (103) is placed on the right side (already cut). By horizontally feeding to the side) position,
As shown in Figure 18.19.23.24, the rush is laid down on its side, with the stem side automatically swinging up to the height of the bundling bed (23), so that its overall shape is curved in an arc when viewed from the front. It is designed to be able to change direction.

That is, the pickle sorting mechanism (E) for this purpose has a work frame (
A pair of upper and lower bored chino cases (139) and (140) are fixedly hung horizontally on the upper and lower hollow chino cases (140), and an endless bored chino case (140) is housed inside each case so as to be able to circulate in the horizontal direction.
41) (142) and its respective chenos (141) (1
42) as a large number at regular intervals, and from the sinking claws (143) (144) which are pivotably mounted in a freely undulating manner,
The scooping claws (143) (144) protrude from the Cheno case (139) (140) when turning to the right, and comb the rushes to separate them one by one, picking up short and small debris. You will have to scoop it out.

In this sense, the left end (starting point of action) of both scooping chenos (141) (142) faces the rear position of the above-mentioned lifting passage (S), and its scooping claws (143) (144)
) is designed to automatically and reliably catch the base side of the rush hanging from the clamping belts (102) and (103). In that case, the lower Sukurichen case (140)
are suspended almost horizontally, whereas the upper cupboard case (139) is arranged in a stacked slanted manner, so that the right end of the cupboard case (141)
The action end point) faces the height position of the binding bed (23).

(145) is the above-mentioned scooped cenocase (139) (1
40), an eighth bevel gear mechanism is installed between the pair of upper and lower gears, and this is transmission-coupled with the transmission shaft (47) as shown in FIG.
Both sukuri chenos (141) (142) go in the same direction,
It is designed to be rotated and driven at the same speed. (
Reference numeral 146) is a scrap scraping belt that is cross-beamed in parallel to the lower position of the lower case (140), and is equipped with a large number of overhanging lugs (147), which are also similar to the above-mentioned hollow ceno (141) (142). It is designed to be rotated in the same direction.

The head side of the rush, which has been subjected to the action of scooping out the debris, uses the clamping position of the tip side as a movable fulcrum by the lateral feeding force of the rush chenos (141) (142), and moves the body (10). It will be floated to the binding bed (23) in a so to speak manner, and as soon as it is picked up by the converging conveyance mechanism (F) on the binding bed (23), the binding mechanism ((
1).

As shown in Figures 25 to 27, the binding mechanism (G) includes a bill guard (148), a release arm (149), and a needle (
150), packer (151), sensing door (15)
2), etc., all of which are located at the right (already cut side) end of the machine body (work 0), and are equipped with the work frame (
The timing gear case (153) is fixedly erected to be taller than the bundling floor (23) from the gear 2), and is pivoted so as to face the bundling floor (23) from inside.

In that case, packer (151) and needle (150)
The discharge arm (149) and the door (152)
is always exposed on the binding floor (23), and its door (
As soon as the needle (152) senses a certain amount of rushes, the needle (1
50), the rushes are bundled into rush bundles (M), and then discharged rearward by the discharge arm (149). A timing gear mechanism (not shown) built into the timing gear case (153) is connected to the primary power distribution shaft (40).
The binding mechanism (G) performs a predetermined motion by being transmission-coupled with the power transmission shaft (45) and the power transmission shaft (45).

Further, the converging conveyance mechanism (F) on the stock head side extends substantially parallel to the nipping conveyance mechanism (C) on the tip side when viewed from above the body (10). And this is a pair of front and rear pulleys (
154) (155) and an endless scraping belt (157) with an overhanging lug (156)
), and the lug (156) hooks the rushes while transporting them to the rear in an orderly manner. The pulley (1,551) on the rear side moves the needle (1,551) from inside to the upper position of the timing gear case (153).
50), release arm (1, 49), door (152)
), it is rotatably supported around a horizontal axis.

(158) is the drive pulley support shaft on the rear side, so the scraping bell (157) and the bundling bed (23)
As a result, a certain rush raking passage (Q) is sectioned and opened between the upper and lower sides. Needless to say, the drive pulley support shaft (158) on the rear side is rotated by the timing gear mechanism. (159) is the belt tensioner of the scraping belt (157), and the belt tensioner (109) of the above-mentioned outer clamping belt (103).
It has the same structure.

(160) is a clipper blade for stock alignment cutting facing the above-mentioned scraping passage (Q), which is in a state of protruding forward by a certain amount 1 t (n) from the front surface of the above-mentioned timing gear case (153), and vertically It is pivoted from the inside to the gear case (153) so as to reciprocate in the direction. In the process of raking into the passage (Q) by the raking belt (157), the stem side of the rushes is prevented from collapsing on its own and colliding with the front of the gear case (153), and This allows for smooth and reliable introduction to the binding mechanism (G).

The rush bundle (M) tied as above is released from the release arm (1
49), the bundling bed (23) is released and transferred to the main deck (24) in a falling manner.
The loading condition of the deck (24) is easily disturbed, and the operator's 1!
It is also difficult to achieve an efficiency of <88 as shown in the figure.

The thickness and weight of the rush bundle (M) are not uniform over its entire length, and only the base side receives the force of the release arm (149), and its loading capacity gradually increases. This is because it becomes

As a countermeasure, the bundle receiver as shown in Figures 25 to 27 is
161) is connected to the bundling floor (23) and the main deck (24).
) is interposed at the boundary with the rush bundle (M), so that the bundle of rushes (M) can be temporarily moored in a stable manner.

That is, the bundle receiving device (161) is controlled from the left and right pairs of the bellow arm (162) which holds the tip side of rush east (M), and the billow arm (163) which holds the stem side. All of them are made of a single metal wire.

The billow arm (162) on the tip side is extended rearward from the bed frame (113) having a pulley support shaft (106) (1 (18)) of the outer clamping bell (103) in the clamping and conveying mechanism (C). As soon as the clamping force of the clamping bells (102) and (103) is released, the tip side of the rush is directly transferred onto the following billow arm (162). (16
4) is the main deck (2) of the below arm (162).
4) It is a stopper curved piece that is bent upward from the rear end facing upward, and temporarily catches and holds the tip side of the rush.

In that case, in the figure, the front end of the billow arm (162) on the tip side is fixedly integrated with the head frame (113) by welding or the like, but instead
2) may also be pivotably attached to the head frame (113) so that it can be folded forward so as to be retracted from above the main deck (24). This is because the amount of rush bundles (M) loaded onto the main deck (24) can be increased without being hindered by this.

The other stock-side pillow arm (163) is in a state substantially parallel to the tip-side pillow arm (162) in plan view, and is attached to the horizontal shaft (165) toward the rear end of the bundling bed (23) so that it can be rotated freely. It is pivoted so that it can be folded forward around its horizontal axis (165) and laid down. Moreover, from the horizontal axis (165) there is a binding floor (
A rotary piece (166) buried in the lower part of the frame (166) is protruded into the body, and the rotary piece (166) is equipped with a coil spring (167) that always biases the above-mentioned bellow arm (163) upward. ! ! It's connected.

By doing this, a bunch of rushes (M) can be attached to the below arm (163).
It is only when the base of the plant is placed on top of the plant that the arm (L63) receives the weight of the rush bundle (M) and sinks slightly to a predetermined position as shown in Figure 27. The predetermined position of the stem-side pillow arm (163) is set to a certain level difference (k) than the tip-side pillow arm (162), corresponding to the fact that the stem side of the rush bundle (M) is thicker than the tip side. ) is lower by that amount.

Also, (168) is a stopper curved piece that is also bent up at the rear end of the pillow arm (163) facing the main deck (24), which temporarily stops the rush from holding the stem side. The rear end of the tip side pillow arm (162) is extended rearward by a certain amount (e).

Therefore, the head side of rush east (M) is closer to the driver's cab (25) than the tip side, and as a result, the operator climbs up the driver's cab (25) and approaches the head side of the rush. becomes easier to hold.

Furthermore, the rush bundle (M) lying on its side on both pillow arms (162) (163) is moored in a stable horizontal position due to the above-mentioned sinking action of the pillow arm (163) on the base side. As soon as it is released to the main deck (24), the stock side pillow arm <163) automatically stays in the push-up position due to the elastic force of the coil spring (167), and is ready for the next injection. Bunch of grass (M)
It will definitely stop receiving.

As mentioned above, the Igusa bundle (M) has a device (161
), the holder is held in place and continues to be released by falling to the main deck (24).
8I of Igusa Tsuku (M) against the main deck (24)
Loading can be performed efficiently and without disturbance, and the operator can easily perform the transfer work to the sub-deck (29) from the driver's cab (25) as in the 2011ffl.

In addition, in the figure, a rush harvester for two-row cutting is shown with the lifting chain case (50) (51) of the lifting device 1 (B).
) by arranging them in parallel with their legs open, the raising passageway (
S) has a triangular or V-shaped opening when viewed from the front,
As long as the passageway (S) is a wide opening and two rows of rushes can be introduced into it in a merging state, the pair of lifting chain cases (50) and (51) can be arranged in a parallel standing state. It is okay to set it up.

Also, use the double-lifting chain case (50) (51) as one piece only on the inside, and pull up the outside chain case 7 (52).
) It is also possible to implement the present invention for cutting a single row of rush by forming it into a simple guide post without a built-in guide post. Furthermore, it goes without saying that the present invention can also be applied to a walking-type rush harvester in which installation of a driver's cab (25) is omitted.

<Effects of the Invention> As described above, in the present invention, the machine body (10) is pivotally connected to the truck frame (11) and the work frame to the front part of the truck frame so as to be able to be lifted forward by the horizontal axis (13). (12
), and a weeding mechanism (A) for uncut rushes and a pulling mechanism (A) for uncut rushes are attached to the weeding sled plate (81) that extends forward along the ground from the lateral end of the uncut side of the working frame (12). At the same time, the engine (B) was installed on the truck frame (11).
6) output shaft (21) and the same distance from the horizontal axis (13)! (d) The intermediate shaft (18) installed at the rear position is horizontally suspended, and the front and rear are connected by a power transmission belt (20), while the power distribution system is installed horizontally on the work frame (12). shaft(
40) and the intermediate shaft (18) are transmission-connected by another transmission belt (41) longer than the transmission belt (20), and the engine is distributed from the power distribution shaft (40). (16) The above weeding mechanism (A
) and a rush harvester which is designed to drive a puller fit (B), a blower which is integrally rotated by the distribution shaft (40) is attached to the uncut side shaft end of the power distribution shaft (40). -Fan (6
7) and its blower fan (67) speed increasing gear mechanism (
At the same time, an air jet nozzle (78) that opens toward the grass during weeding is installed in the middle of the weeding plate (81), and the nozzle (78) and blower Fan (67)
Since these are connected to each other by the air discharge pipe (77) whose front part is inclined, the problems of the prior art mentioned above can be improved.

In other words, in the case of the present invention, the horizontally suspended power distribution shaft (40) is installed on the work frame (12) forming the front part of the fuselage (10).
Above, a blower fan (67) rotated by this
is installed, the power transmission belt (72) of the prior invention mentioned in WEIi becomes unnecessary, and the power transmission belt (72) of the present invention corresponding to another power transmission belt (72) of the prior invention (59) is attached.
41), the blower fan (67) can be efficiently rotated, and the driver's cab (25), which has a limited space, can be made more spacious.

Moreover, the blower fan (67) can be installed on the work frame (12) by means of the horizontally mounted power distribution shaft (40).
is pivotally supported, so this and the air jet nozzle (78
) as an air discharge pipe (77) that communicates with
It is possible to use a very short length, which effectively eliminates the loss of air blowing action. Although a rigid body different from that of the previous invention is adopted as the air discharge pipe (77), the mounting condition is unstable due to the upward movement of the work frame (12) when lifting the work frame (12) with respect to the truck frame (II). It will not be affected by oxidation or other negative effects.

Further, the blower is located on the way of the power distribution shaft (40).
Since the speed increasing gear mechanism (71) of the fan (67) is also assembled, the fan (67) can be rotated at extremely high speed to generate powerful air.

From this point of view, the blower fan (67) can also be made smaller and flatter, and has the effect of being able to be efficiently incorporated into the work frame (12) in a space-saving manner.

Furthermore, if the configuration of claim 2 is adopted, when the work frame (12) is lifted, not only the weeding mechanism (A) and the pulling mechanism (B) but also the blower fan (67) are activated. Since the drive can also be stopped automatically, there is no chance of forgetting to stop the drive, and it can be said to be extremely safe.
