Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the following description, the side on which the handle 404 is disposed is referred to as the rear side, and the opposite side, i.e., the side on which the engine 41 is disposed, is referred to as the front side. The right-hand side is set to the right and the left-hand side is set to the left toward the front side of the machine body.

As shown in fig. 1 to 5, the transplanter 10 of the present embodiment includes a traveling vehicle body 40 capable of traveling forward, a control handle 404 for walking control provided at the rear part of the traveling vehicle body 40, a planting device 42 for planting seedlings in a field, and a seedling supply device 43 for supplying seedlings to the planting device 42.

The traveling vehicle body 40 is provided with a transmission case 39 at a front portion of the vehicle body, and an engine 41 as a driving device is provided on a front side of the transmission case 39. An axle cover for covering an axle capable of adjusting the track width by changing the left and right positions of the traveling member 44 as the rear wheel is connected to the lower portion of the rear side of the body on both the left and right sides of the transmission case 39, and a traveling transmission case 38 is vertically rotatably attached to each of the outer ends of the body of the axle cover, and the traveling transmission case 38 transmits the driving force to the traveling member 44 provided on the rear side of the body.

The left and right travel members 44 are disposed between the left and right sides of the frame of the vehicle body and the travel transmission case 38, respectively, thereby suppressing the left and right width of the machine body. However, if the left and right travel members 44 are configured to be able to be mounted on the outside of the machine body of the travel transmission case 38 so as to correspond to conditions such as a ridge width for performing a seedling transplanting operation, the number of operation conditions that can be met can be increased.

More specifically, the left and right axle covers are rotatably attached to the inner axles (not shown) as fulcrums, the travel transmission case 38 is attached to each of these axle covers, and the travel transmission case 38 is vertically rotated by the rotation of the axle covers by the expansion and contraction of a lifting hydraulic cylinder or a swing cylinder, which will be described later.

As shown in fig. 1 to 5 and 9, the transmission case 26 is branched to supply the driving force to the transplanting device 42 and the seedling supply device 43 by transmitting the power from the transmission case 39, a base plate 400 is provided on the transmission case 26, the base plate 400 covers at least right and left side surfaces and a back surface of the transmission case 26, and a frame support 401 is detachably provided at a rear portion of the base plate 400 by a fixing member such as a bolt. The frame support 401 is provided with a handle frame 402 protruding upward toward the rear side of the machine body in a shape that describes an arc, and a manipulation unit 403 and a manipulation handle 404 are provided at the rear portion of the handle frame 402, and the manipulation unit 403 operates vertical adjustment of the vehicle height, connection/disconnection of transmission of traveling and transplanting work, and the manipulation handle 404 is gripped by an operator when the machine body is manipulated by the operator such as when the operator does not move the seedling transplanting. The steering handle 404 has a shape that is curved toward the left and right of the body with the handle frame 402 as the center, and is provided with side clutch operating levers 405 on the left and right rear sides to connect and disconnect the transmission to and from the travel member 44. Further, a 1 st throttle lever 406 that increases or decreases the output of the engine 41 is provided on either the left or right side of the joystick 404.

A steering panel 47a is provided between the right and left sides of the steering handle 404, and the steering panel 47a includes: a vehicle height adjusting lever 123 for adjusting the height of the traveling vehicle body 40 by extending and contracting the lifting hydraulic cylinder; a main clutch lever 125 that connects/disconnects transmission of driving force to the left and right travel transmission cases 38 and 26; a 1 st engine switch 407 that switches whether or not the engine 41 can be started and performs a stop operation; and a main shift lever 150 that switches the travel transmission of the traveling vehicle body 40 to any one of a traveling speed, an insertion operation speed, a traveling neutral position, and a reverse position.

When the start of the engine 41 is permitted, the operator pushes the 1 st engine switch 407 and rotates it to operate it to the on position. Thus, when the starting operation of the engine 41 is performed, the engine 41 is started.

When the operator pushes the 1 st engine switch 407 slightly to stop the engine 41, the operator switches the switch to the off position by the force of a built-in torsion spring (not shown), thereby bringing the engine 41 to a stop state.

In the off operation, the 1 st engine switch 407 is pushed slightly, and thus, the running and the transplanting can be stopped immediately. Thus, when reaching the end of the ridge, the running and the transplanting are immediately stopped, thereby preventing the transplanting action of the seedlings from being carried out at the positions which are not on the ridge, and reducing the additionally consumed seedlings. In addition, when the machine body is moved to the ridge for the next transplanting operation, no additional movement is generated, thereby reducing fuel consumption and operation time.

A seedling supply device 43, which will be described later, is provided on the upper portion of the transmission case 26 in front of the machine body of the manipulating handle 404, and the seedling supply device 43 transfers seedlings to be thrown by a worker to the left and right transplanting hoppers 20a, 20 b. Further, a reinforcing frame 152 in the front-rear direction is provided across the rear portion of the seedling feeding device 43 and the reinforcing coupling support 151, the reinforcing coupling support 151 is provided on the upper portion of the rear side of the handle frame 402 and the front side of the manipulation panel 47a, and the reinforcing frame 152 improves the strength of the vicinity of the manipulation handle 404 and the seedling feeding device 43 and reduces vibration.

When the capacity of the tank is increased, the front-rear and left-right widths of the tank are increased in addition to the load. When the water tank is loaded in conjunction with the transplanter of the present invention, the upper side of the travel transmission case 38 has no problem in terms of the front-rear width, but the left-right width cannot be secured, and even if the left-right width can be secured, the left-right width may come into contact with the inside of the travel member 44 and become resistance, and therefore, an open space outside the body of the travel member 44 needs to be used.

In order to support the radiator 610 on the body outer side of the travel member 44, as shown in fig. 11 to 14, an inner support 611 is provided on the rotation base side of the travel transmission case 38, that is, on the body front side and on the inner side. The inner support 611 has an upper side projecting upward from the upper surface of the travel transmission case 38 and a lower side projecting downward from the lower surface of the travel transmission case 38. Further, an outer support 612 corresponding to the inner support 611 is attached to the front side and the outer side of the body of the travel transmission case 38, the lower portion of the outer support 612 protrudes below the travel transmission case 38, and a receiving portion for receiving the columnar member above the body with respect to the upper surface of the travel transmission case 38 is formed at the upper portion of the outer support 612.

As a receiving portion formed in the outer support 612, a receiving member 613 which is a hollow columnar member is attached in the left-right direction of the machine body. The receiving member 613 is fixed to the outer support 612 by welding or the like to receive the load of the tank 610.

Further, a bent portion 612a is formed toward the outside of the housing on the housing rear side of the outer support 612, and the upper end portion of the bent portion 612a is welded in contact with the rear side of the receiving member 613, thereby improving strength. The receiving member 613 is provided with a receiving nut into which a bolt is inserted on an outer peripheral surface thereof, and the bolt is screwed into a thread groove (not shown) formed in the inner support 611 and is inserted into and fastened to a mounting hole formed on a lower side of the inner support 611 and the outer support 612, thereby improving mounting strength. Further, mounting holes are formed in parts of the surfaces of the inner support 611 and the outer support 612 that contact the travel transmission case 38, and nuts are mounted on threaded shafts exposed from the inside of the travel transmission case 38, thereby securing load resistance in the vertical direction.

Further, left and right base portions of the tank guards 615 that support the outer periphery of the water tank 610 are connected to the connecting members 614 having shapes corresponding to the receiving members 613, respectively. A hole portion into which the coupling member 614 is inserted is formed on the base portion side of the box guard 615, and after the coupling member 614 is inserted, the base portion is fixed by welding to improve strength.

Further, the portions of the tank guard 615 located on the left and right sides of the water tank 610 form an upper inclined portion 615a inclined upward from the base side to the vicinity of the central position in the front-rear direction, and are in a posture substantially parallel to the ground surface of the running member 44 from the vicinity of the central position in the front-rear direction to the rear, and are shaped like へ in a side view.

A front side and a rear side of a front and rear support plate 616, which has the longitudinal direction of the machine body as the front and rear direction, are coupled between the rear side of the box guard 615 and the front and rear of the coupling member 614, respectively. A front side inflected support portion 616a flexed upward is formed on the front portion side of the front and rear support plate 616, and a rear side inflected support portion 616b flexed upward is formed on the rear portion side of the front and rear support plate 616. The rear support bent portion 616b protrudes upward from the front support bent portion 616a, and is configured to be easily inserted into and removed from the water tank 610 due to the structure in which the upper inclined portion 615a is located downward toward the front side of the machine body.

Further, a reinforced inflection portion 616c that is curved toward the front side of the body is formed on the lower side of the front support inflection portion 616a, specifically, on the lower side of the coupling member 614, and the upper surface of the reinforced inflection portion 616c is coupled to the lower surface of the coupling member 614. Further, the outer side of the housing in the portion between the front and rear of the front and rear support plates 616 is bent downward of the housing, thereby further improving the strength.

Further, the front side bent support portion 616a is bent toward the front side of the body in the vicinity of the upper end, i.e., on the upper side of the body with respect to the position coupled to the coupling member 614, and the rear side bent support portion 616b is bent toward the rear side of the body in the vicinity of the upper end, i.e., on the upper side of the body with respect to the position coupled to the rear portion of the tank guard 615, thereby facilitating the entry and exit of the water tank 610.

Further, the front and rear support plates 616 are provided with one left and right support plate 617 for supporting both left and right sides of the water tank 610, or with a plurality of left and right support plates 617 spaced apart from each other. When one left and right support plate 617 is provided, the front and rear support plates 616 in the front-rear direction are disposed at or near the front-rear intermediate position. Left and right support bent portions 617a and 617a bent upward are formed on left and right sides of the left and right support plates 617, respectively, and upper end portions of the left and right support bent portions 617a and 617a are connected to the box guard 615 by welding or the like, respectively.

The upper ends of the left and right support bent portions 617a, 617a are located at the same or substantially the same position on the left and right sides, but the support bent portions 617a located on the outer side of the machine body are coupled inside the frame of the box guard 615, and the support bent portions 617a located on the inner side of the machine body are coupled outside the frame of the box guard 615.

This forms a tank support 618 for supporting the water tank 610 to be freely inserted and removed.

The tank support 618 can be detached by pulling out the coupling member 614 from the receiving member 613. Accordingly, since the left and right width of the machine body can be made compact by detaching the tank receiver 618 when the water tank 610 is not loaded, exposure from the cargo bed of the light truck is prevented, and a storage space can be easily secured in a warehouse or the like.

On the other hand, when the water tank 610 is loaded to perform the seedling transplanting work, it is necessary to prevent the tank support member 618 from coming off, but when the coupling member 614 can move in the left-right direction, the weight balance may be disturbed, and the traveling direction of the traveling vehicle body 40 and the seedling transplanting posture may be greatly disturbed.

In order to restrict the movement of the coupling member 614 in the left-right direction during operation and to enable easy attachment and detachment of the tank receiver 618 during non-operation, a plurality of adjustment holes are formed in the receiving member 613 and the coupling member 614 at intervals in the left-right direction, and the attachment state and the detachment state can be switched by attaching and detaching bolts and nuts while the positions of the adjustment holes of the receiving member 613 and the coupling member 614 are aligned with each other.

In the above configuration, when the box support 618 is removed, the mounting members need to be stored. If the mounting member is mounted to the adjustment hole formed in the receiving member 613 or the coupling member 614, the mounting member can be used immediately when the tank support 618 is mounted, but it is necessary to perform a work such as temporarily removing a nut from a bolt.

Further, although the mounting member needs to be removed when the transplanter is brought back from the field, if the box support member 618 is firmly fastened to prevent the box support member from falling off during the operation, the mounting member cannot be removed without using a tool, requiring additional time, and taking time and effort to bring the tool to the field.

In order to cope with this problem, it is conceivable that a base portion of the pivotal arm portion of the pipe pin is attached to the receiving member 613, and an attachment pin is provided at an end portion of the pivotal arm portion. Thus, even if the mounting pin is pulled out, the pivot arm portion is provided to the receiving member 613, and therefore, the mounting pin is prevented from being lost.

A shock absorber support frame 108 shaped like コ in a front cross-sectional view is provided on the front side and both the left and right sides of the machine body of the transmission case 39 so as to project toward the front side of the machine body. A damper (damper) 109 protruding toward the front side of the machine body is provided in front of the left and right damper support frames 108.

As shown in fig. 6 to 8, the damper 109 is composed of a damper plate 109a formed by bending the front side and both left and right sides of the body of the plate body downward, a front weight 109b attachable to and detachable from the upper surface of the damper plate 109a, and a damper rod 109c extending in the left-right direction from the damper plate 109 a. The front weight 109b is made of a heavy and hard material and has a shape protruding toward the front side of the machine body from the cushion plate 109 a.

Thus, the front weight 109b, which is a block having a weight and hardness, protrudes most forward of the machine body, and therefore damage can be prevented from reaching the cushion plate 109a when contacting an obstacle.

Recesses (not shown) having openings on the lower side of the body are formed on the body front side and the body lower side of the left and right shock absorber support frames 108, and front beam frames 110 having the longitudinal direction of the body in the left-right direction are inserted into these recesses and fixed.

By providing this front beam frame 110, the right and left bumper support frames 108 and the transmission case 39 are also formed into a rectangular frame on the front side of the machine body, and therefore the strength of the front side of the machine body is improved. In particular, when the shock absorber 109 comes into contact with an obstacle, the left and right shock absorber support frames 108 are inserted into and fixed to the front beam frame 110, and therefore, damage and impact are not easily transmitted to the rear portions of the left and right shock absorber support frames 108.

Further, when the transmission case 39 is assembled to the machine body, the left and right positions can be adjusted while fixing the front and rear positions of the transmission case 39 by inserting the concave portions of the left and right bumper support frames 108 into the front beam frame 110 and then moving the same in the left and right directions, and therefore, the assembly work is prevented from being delayed due to the deviation of the mounting position of the transmission case 39.

The rear portion of the engine 41 is mounted on the front and left and right sides of the transmission case 39, and the front portion of the engine 41 is mounted on an engine mount disposed near the left and right center portions of the front beam frame 110, but the shock absorber support frame 108 on which the engine 41 is disposed and the engine 41 are disposed at a vertical distance from each other. That is, the damper support frame 108 is not a member that receives the engine 41 from below.

According to the above configuration, since the impact when the shock absorber 109 contacts an obstacle can be prevented from being transmitted from the shock absorber support frame 108 to the engine 41, damage to the engine 41 and malfunction due to the impact can be prevented.

Further, the shock absorber support frame 108 is configured not to easily affect the mounting state of the engine 41 even if it is deformed by an impact, and is configured to be capable of performing work and movement by the power of the engine 41 even if the shock absorber 109 is damaged.

Pedal support plates 111 are attached to the left and right sides of the cushion plate 109a, and the pedal support plates 111 have left and right recesses to which cushion rods 109c are attached. The left and right pedal support plates 111 are supported via reinforcing arms 112, and the reinforcing arms 112 are provided on the left and right sides of the body rear side of the front frame 110.

The left and right pedal support plates 111 have a flat upper surface, and a body front portion of a front riding pedal 113 is attached to a body left side which is a body left side on the left and right sides of the traveling vehicle body 40, and an operator steps on the front riding pedal 113 when ascending and descending from the body front side. On the other hand, an inter-plant switching cover 114 is formed on the other side of the right and left of the body, i.e., the right side of the body, and the inter-plant switching cover 114 supports an inter-plant main shift lever 801 and an inter-plant sub shift lever 802 for setting a so-called inter-plant distance between seedlings planted in the planting hoppers 20a and 20b, and an planting shift lever 803 for selecting the 1 st planting speed or the 2 nd planting speed when the main shift lever 150 is operated to the planting speed.

The front boarding step 113 includes a lower step portion 113a located on the front side of the machine body and on the lower side in the vertical direction, an upper step portion 113b located on the rear side of the machine body and on the upper side in the vertical direction with respect to the lower step portion 113a, and an intermediate inclined portion 113c located between the lower step portion 113a and the upper step portion 113b and inclined in a twisted manner in the outer direction of the machine body. A plurality of anti-slip protrusions 113d are formed on the surface of the lower step portion 113a, and the intermediate inclined portion 113c is formed to have an inclination angle at which an operator cannot easily step on the foot psychologically during ascending and descending, and to have a length in the front-rear direction that the operator crosses over when moving between the lower step portion 113a and the upper step portion 113 b.

On the other hand, the inter-plant switching cover 114 is composed of a lower table portion 114a located on the front side of the machine body and on the lower side in the vertical direction, an upper table portion 114b located on the rear side of the machine body and on the upper side in the vertical direction with respect to the lower table portion 114a, and a rod attachment portion 114c located between the upper and lower sides of the lower table portion 114a and the upper table portion 114b, and the rod attachment portion 114c is twisted and inclined in the machine body outer side direction and is formed with a movement groove in which the inter-plant main shift lever 801, the inter-plant sub shift lever 802, and the main shift lever 150 move, respectively.

The front-side riding step 113 and the inter-plant switching cover 114 are formed in a bilaterally symmetrical shape, and a member provided on one of the left and right sides of the machine body may be the inter-plant switching cover 114, and a member provided on the other of the left and right sides of the machine body may be the front-side riding step 113.

Side steps 118 are provided on the rear sides of the body of the upper step portion 113b and the upper base portion 114b, respectively, and the side steps 118 serve as a foot rest for a worker to get on and off the body from the side. The side step 118 is configured by arranging a plate body vertically and horizontally in a frame to form a plurality of space portions, and dropping soil attached to the sole of the operator downward. Further, a center step, which is a foot-engaging portion of an operator who engages the vehicle, is detachably provided between the left and right sides of the left and right side steps 118.

The floor pedal 122 is constructed as described above.

The front side boarding step 113, the inter-trunk switching cover 114, the left and right side steps 118, and the center step are mounted independently, that is, not fastened together by one mounting member (bolt or the like). Thus, when each pedal structure is removed during local maintenance work, it is not necessary to remove other pedal structures, and the efficiency of the maintenance work is improved.

A lower part of the front side boarding pedal 113 is provided with an ascent and descent assist mechanism on which an operator steps his foot when ascending and descending with respect to the front side boarding pedal 113. The riding and landing assisting mechanism is composed of the following parts: an outer support arm 171 which is positioned outside the body, has an L-shape in side view, and has a 1 st protruding portion 171a protruding forward of the body below the bent portion; an inner support arm 172 located inside the body, having an L-shape in front view, and having a 2 nd projecting portion 172a projecting outward of the body below the bent portion; and a boarding/alighting assist pedal 173 provided over the 1 st projection 171a and the 2 nd projection 172 a.

The outer support arm 171 is fastened together with the pedal support plate 111 by the common fastening bolt 174 … and is mounted on the running vehicle body 40. The inner support arm 172 is fastened together with the cushion plate 109a by a common fastening bolt 174 … and is attached to the running vehicle body 40.

Thus, since the plurality of members are fastened by the common fastening bolt 174 …, the strength of the vicinity of the front side of the body of the traveling vehicle body 40 is increased, and the reduction in durability due to the load when the operator rides on or off the vehicle is reduced.

Further, by providing the riding-down assist pedal 173, even if the height of the traveling vehicle body 40 is increased in accordance with the height of the ridge or the like, the operator can step on the riding-down assist pedal 173, step on the lower step portion 113a of the front riding pedal 113 to take the vehicle, and get off the vehicle in the reverse operation, so that the operator does not need to raise his foot during riding down or to jump down slightly, and the burden on the body of the operator is reduced.

Further, since the riding/landing assist pedal 173 is provided over the 1 st protruding portion 171a and the 2 nd protruding portion 172a, the outer support arms 171 and the inner support arms 172 are not positioned within the lateral width of the riding/landing assist pedal 173, and therefore, the feet of the operator are prevented from coming into contact with the outer support arms 171 and the inner support arms 172.

On the other hand, when the vehicle height of the traveling vehicle body 40 is lowered or in the transplanting work, the riding and lowering assist mechanism is not required, but the riding and lowering assist mechanism may contact the ridge surface or the normal surface of the ridge depending on the vehicle height to collapse the ridge, thereby lowering the transplanting accuracy of the seedling.

In order to prevent this, the base portions of the outer support arm 171 and the inner support arm 172 may be fitted with double nuts (not shown), the outer support arm 171 and the inner support arm 172 may be fitted so as to be rotatable about the common fastening bolt 174 … as a rotation fulcrum, and the boarding/alighting assistance mechanism may be configured to be rotatable up and down.

According to the structure, the lifting auxiliary mechanism can rotate towards the upper part far away from the ridge surface when not needed, so that the lifting auxiliary mechanism is prevented from collapsing ridges, and the transplanting precision of seedlings is maintained.

As shown in fig. 1 to 8, a ridge end sensor support 182a that supports a ridge end sensor 182 is provided at a lower portion of the inter-plant switching cover 114, and the ridge end sensor 182 rotates downward by its own weight to contact the ridge surface, and further rotates downward when the traveling vehicle body 40 reaches the end of the ridge without contacting, and operates a notification device 181 that notifies the operator of the arrival at the end of the field. The notification device 181 is a buzzer or a lamp mounted on each part of the traveling vehicle body 40, or a communication device that notifies an information terminal provided in an operator.

The ridge end sensor 182 is configured to be provided with a sensor arm 183 so as to be rotatable, a ridge surface contact roller 184 is rotatably attached to a lower portion of the sensor arm 183, a ground contact biasing spring 185 for biasing the sensor arm 183 downward is provided, and a ridge end detection switch 186 which is turned on (or off) when the angle of the ridge end detection switch is equal to or greater than a predetermined angle is provided at a base portion of the sensor arm 183. The ground contact biasing spring 185 is configured such that the upper end portion side is attached to a detection adjustment plate 187 that can be adjusted in angle along the elongated hole, and the angle of operation can be changed in accordance with the ridge height.

The ridge end sensor 182 is brought into contact with the ridge surface by adjusting the height of the traveling vehicle body 40 at the start of the seedling transplanting operation. By bringing the freely rotatable ridge surface contact roller 184 into contact with the ground, the ridge surface is less likely to collapse, and fine irregularities can be flattened, thereby improving the accuracy of transplanting seedlings.

When the traveling vehicle body 40 further moves forward and reaches the end of the ridge and the ridge surface contact roller 184 does not contact the ridge surface, the sensor arm 183 rotates downward by the urging force of the contact urging spring 185 and the weight of the sensor arm 183 and the ridge surface contact roller 184, and the ridge end detection switch 186 is not pressed. When the ridge end detection switch 186 is not pressed, the notification device 181 is energized, and thereby the notification device 181 operates to notify the operator that the vicinity of the body front end of the traveling vehicle body 40 has reached the ridge end.

Further, since there are several remaining planting spaces in the ridge at the time when the ridge end sensor 182 detects the ridge end, the operator puts the seedlings, the number of which is the number of seedlings to be planted in the remaining planting spaces, into the seedling supply device 43 and prepares to stop the operation without immediately stopping the machine body.

Therefore, the operator can know the approaching ridge end without turning back, so that the machine body can be stopped at the timing of finishing the transplanting of the seedlings on the ridge, and the fuel consumption caused by extra driving and the moving distance towards the next operation row are prevented from being increased.

Further, since the number of seedlings to be loaded into the seedling supply device 43 can be adjusted when the ridge ends are close, even if the stop operation of the transplanting operation traveling is delayed and the transplanting operation is performed by the transplanting hoppers 20a and 20b, the seedlings are prevented from being released to a portion other than the ridge.

As shown in fig. 4, 6, and 7, the sensor arm 183 may be a pair of left and right sensor arms 183a, and the ridge surface contact roller 184 may be rotatably provided with the left and right ridge surface contact rollers 184a, and the left and right ridge edge detection switches 186, respectively.

Thus, when one of the left and right sensor arms 183, 183 is rotated downward and one of the corresponding ridge end detection switches 186, 186 is not pressed, the notification device 181 is operated, and thus even if the ridge end is disturbed in shape due to wind and rain collapse, the ridge end is easily detected, and the operator can perform the operation of stopping the insertion operation traveling well at regular time.

Further, front wheels 45 rotatably supported are provided on both left and right sides of the body front side of the traveling vehicle body 40 and on the body front side of the traveling member 44 via a lateral frame 16, and the lateral frame 16 is provided on a lower portion side of the front beam frame 110 and protrudes in the body left-right direction.

The distal ends of the wheel drive shafts extending from the transmission case 39 to the left and right outer sides enter the rotational axis position of the front portion of the traveling transmission case 38, and the power for traveling is transmitted to the transmission mechanism in the traveling transmission case 38 via the traveling portion system transmission portion in the transmission case 39. The power for traveling is transmitted to the transmission axle of traveling transmission case 38 via a transmission mechanism in traveling transmission case 38, and traveling member 44 is rotationally driven.

A vertically-rotatable drive unit that vertically rotates the travel transmission case 38 about a pivot point on the front side of the travel transmission case 38 is connected to the travel transmission case 38. Specifically, an arm 13 extending upward is integrally attached to the traveling transmission case 38 at a portion attached to the transmission case 39, and the arm 13 is connected to both left and right sides of a connecting body attached to a piston rod end of a hydraulic cylinder for lifting fixed to the transmission case 39. One of the left and right sides (right side) is connected by a connecting rod, and the other side (left side) is connected by a left and right control hydraulic cylinder which can perform telescopic operation corresponding to the inclination of the machine body.

When the lifting cylinder is operated to project the piston rod rearward of the machine body, the left and right arms 13 are rotated rearward, and the travel transmission case 38 is rotated downward in response to this rotation, and the machine body is raised. Conversely, when the piston rod of the hydraulic cylinder for elevation moves forward in the machine body and retracts into the cylinder, the left and right arms 13 rotate forward, and the travel transmission case 38 rotates upward in association with this rotation, and the machine body descends.

The lifting hydraulic cylinder is operated by a ridge surface sensor 14, and the ridge surface sensor 14 is in contact with the ridge surface and is operated along with the variation of the vertical interval between the machine body and the ridge surface. The operation of the ridge surface sensor 14 is an operation of detecting the height of the upper surface of the ridge with reference to the position of the machine body, and the machine body is set to a set height corresponding to the height of the upper surface of the ridge based on the detection operation of the ridge surface sensor 14, and the elevation hydraulic cylinder is operated by this configuration.

When the left and right horizontal control cylinders perform the telescopic operation, the left arm 13 connected to the left and right horizontal control cylinders is rotated to move only the left traveling member 44 up and down, thereby tilting the machine body left and right. The left-right horizontal control hydraulic cylinder is configured to operate based on a detection result of a sensor that detects a left-right inclination of the body with reference to the left-right horizontal, and to make the body horizontal.

As shown in fig. 1, 2, and 5, the lateral frame 16 is attached to the front beam frame 110 so as to be swingable around an axial center in the front-rear direction, and vertical frames 17, which are vertically long, are attached to both left and right sides of the lateral frame 16. The front wheels 45 are rotatably mounted on a front wheel axle 18, and the front wheel axle 18 is fixed to the side of the lower end of the vertical frame 17. Therefore, the right and left front wheels 45 are swingably rotatable about the axis in the front-rear direction at the right and left center of the machine body. The vertical frame 17 is configured to be vertically adjustable with reference to both left and right side portions of the horizontal frame 16, and to be capable of adjusting the height of the front wheel 45.

The operating handle 404 is provided at the rear of the body, on the rear side of the body with respect to the transmission axle of the travel member 44. Specifically, the front end portion is fixed to the transmission case 39.

The body frame extends rearward from the left and right center of the body, and extends obliquely rearward and upward from the front and rear intermediate portions.

The handle bar 404 extends rearward from the rear end of the body frame in the right and left directions, and each rear end serves as a grip portion of the handle bar 404.

In fig. 2, the grip portion is configured to be divided into left and right portions, but the left and right rear end portions of the joystick 404 may be coupled to each other in the left and right directions, and the coupled portion may be used as the grip portion.

The insertion device 42 has: a plurality of mouth-shaped inserters, the tail ends of which are downward; a vertical movement mechanism 21 for vertically moving the implant between a position where the lower end of the implant is above the field surface and a position where the lower end is below the field surface; and an opening/closing mechanism for opening/closing the transplanting device between a closed state in which the lower end portion of the mouth-shaped transplanting device is closed and the transplanting device can receive the seedlings from above and store the seedlings inside and an open state in which the lower end portion of the transplanting device is opened left and right and the seedlings stored inside can be discharged downward.

As shown in fig. 1 to 5, the planting device 42 of the present embodiment is configured to plant in two rows in which the 1 st planting hopper 20a and the 2 nd planting hopper 20b are arranged side by side on the left and right. These 1 st insertion hopper 20a and 2 nd insertion hopper 20b are respectively attached to vertical movement mechanisms 21, and the vertical movement mechanisms 21 are provided on both right and left sides of a transmission case 26 to which power is transmitted from a transmission case 39.

Each seedling container 22 has a cylindrical body having an upper opening and a lower opening, and a bottom cover for opening and closing the lower opening of the cylindrical body, and are connected to each other in a ring shape.

The moving mechanism rotates the connected seedling containers 22 to the left along an oval annular track that is long in the left-right direction when the machine body is viewed in plan, in a state where the connected seedling containers 22 pass above and near the left and right transplanting hoppers 20a, 20 b.

The seedling dropping mechanism opens the bottom cover of the seedling receptacle 22 at a position above the transplanting hoppers 20a, 20b corresponding to the seedling receptacle 22.

In the present embodiment, a cylindrical outer peripheral portion is formed on the outer periphery of the seedling container 22, an engaging portion (circular hole) connected from the outside in a rotatable manner is provided on the cylindrical outer peripheral portion, and a plurality of connected bodies connecting 2 seedling containers 22 are formed. The engaging portion of the coupling body is rotatably connected to the cylindrical outer peripheral portion of the seedling receiving body 22, and the adjacent seedling receiving bodies 22 are rotatably coupled with each other with the cylindrical outer peripheral portion serving as a rotation axis, thereby coupling the plurality of seedling receiving bodies 22 to each other. That is, the seedling container 22 and the coupling body are configured to be coupled to each other like a circulating chain.

Accordingly, in the seedling storage body 22, since the interval between the adjacent seedling storage bodies 22 is not changed in both the linear portion that moves linearly and the arc-shaped portion that moves in an arc shape, a positional deviation of the seedling storage body 22 with respect to the left and right transplanting hoppers 20a, 20b is less likely to occur at the portions where seedlings are supplied from the seedling storage body 22 to the left and right transplanting hoppers 20a, 20b, and appropriate seedling transplanting can be performed by appropriately supplying seedlings.

The moving mechanism of the seedling supply device 43 is configured to wind the seedling storage bodies 22 connected to each other like an endless chain around the arc-shaped cut-out portions on the outer peripheries of the left and right sprockets, and to rotate the respective seedling storage bodies 22 by driving the left and right sprockets to rotate by power taken out from the transmission case 26.

The circulation movement path around which the seedling container 22 circulates is a long circle having a linear portion extending in the left-right direction in plan view and an arc-shaped portion curved in an arc shape from the linear portion to the front side or the rear side by a sprocket, and is disposed inside the body with respect to the left and right traveling members 44.

The operator sits on the work seat 46 or stands on the floor step 122 to perform the seedling supply work to the seedling supply device 43, but when there is no seedling for replenishment, it is necessary to stop the running of the running vehicle body 40 or stop the driving of the transplanting hoppers 20a, 20 b. Further, when the traveling speed or the ascending/descending progress of the planting buckets 20a and 20b is faster than the progress of the operator, it is necessary to change the speed to a speed at which the operation is easy.

As shown in fig. 4 and 5, in order to perform the above-described operation while sitting on the work seat 46 or without going down from the floor step 122, a 2 nd engine switch 408 is provided on the front and left and right end portions of the body of the seedling supply device 43, that is, on the right hand side of the operator sitting on the work seat 46, the 2 nd engine switch 408 is switched to enable or disable the start of the engine 41 and is provided with a 2 nd throttle lever 409 so as to be rotatable in the body left-right direction at a position inside the body (the other side of the left and right sides of the body) than the 2 nd engine switch 408, and the 2 nd throttle lever 409 is provided to increase or decrease the output of the engine 41.

The method of operating the 2 nd engine switch 408 is the same as that of the 1 st engine switch 407, but if both of the 1 st engine switch 407 and the 2 nd engine switch 408 are not operated to the on position, the engine 41 is not started.

Accordingly, when the operator grips the handle 404 at the rear side of the machine body during movement or the like, the stop operation can be performed by the 1 st engine switch 407, and when the operator rides on the traveling vehicle body 40 during seedling transplanting work or the like, the engine 41 can be stopped by turning off the 2 nd engine switch 408, so that the operator does not need to get off the 1 st engine switch 407 from the traveling vehicle body 40 during riding, and the operation causing a problem in transplanting or the machine body can be interrupted.

Further, since the 2 nd throttle lever 409 can be operated from the traveling vehicle body 40, it is not necessary to move the traveling vehicle body 40 up and down when increasing or decreasing the output of the engine 41, and the work efficiency and the work accuracy are improved.

The left and right insertion hoppers 20a, 20b are disposed on the rear side of the transmission axle.

The seedling supply device 43 is configured to supply seedlings by moving the seedling storage body 22 around one turn corresponding to the left and right transplanting hoppers 20a, 20 b.

The transplanting hoppers 20a, 20b drop-supply seedlings from the seedling storage body 22 at the 1 st and 2 nd drop-supply positions, respectively.

Seedling containers 22 for storing seedlings to be dropped and supplied are provided corresponding to the left and right transplanting hoppers 20a, 20b, respectively, and the bottom cover is opened only when the seedling containers 22 come above the corresponding left and right transplanting hoppers 20a, 20b, and is not opened above the non-corresponding left and right transplanting hoppers 20a, 20 b.

That is, only when the seedling receptacle 22 corresponding to the transplanting hopper 20a comes to the 1 st drop-and-supply position and only when the seedling receptacle 22 corresponding to the transplanting hopper 20b comes to the 2 nd drop-and-supply position, the bottom cover of each is opened and seedlings are supplied to the corresponding transplanting hoppers 20a, 20 b.

The 1 st and 2 nd drop-down supply positions are configured to be movable to corresponding positions when adjusting the rows of the left and right implant hoppers 20a, 20 b.

The operation cycle of the moving mechanism is set in synchronization with the operation cycle of the vertical moving mechanism 21, and the seedling receiving bodies 22 corresponding to the left and right transplanting hoppers 20a, 20b are combined to form one seedling receiving body unit, and a plurality of the seedling receiving body units are connected, so that the seedling receiving bodies 22 can supply seedlings corresponding to the left and right transplanting hoppers 20a, 20b without seedling leakage supply while passing through the left and right falling supply positions in series, and the seedlings can be supplied corresponding to the left and right transplanting hoppers 20a, 20b without surplus, so that the seedling receiving bodies 22 which are not supplied with seedlings are not generated after passing through the left and right falling supply positions.

The transplanter 10 of the present embodiment is provided with soil covering leveling wheels 37 at positions near the rear left and right sides of the seedling planting positions of the left and right planting hoppers 20a, 20b, respectively, and the soil covering leveling wheels 37 are used for soil covering leveling corresponding to the seedlings planted in the left and right planting hoppers 20a, 20 b. The left and right soil levelling wheels 37 are composed of: leveling arms 370 and 370 each formed by bending a bar into a J-shape in a plan view, and each independently rotatable up and down; and leveling rotating bodies 371, 371 provided on the rear sides of the left and right leveling arms 370, 370 so as to be rotatable in a pair of left and right directions, respectively.

The one end portion of the leveling arm 370 on the inner side of the body is vertically rotatably attached to the rear portion side of the traveling vehicle body 40, and the leveling arm 370 bends the rear portion of the straight portion protruding rearward upward, then bends outward and downward, and further bends forward at the same vertical position as the straight portion on the inner side of the body. Further, the flat rotating body 371 on the outer side of the machine body out of the left and right flat rotating bodies 371, 371 is provided on the straight line portion on the outer side of the machine body which is bent toward the front side of the machine body, and the flat rotating body 371 on the inner side of the machine body is fitted on the straight line portion on the inner side of the machine body.

According to the above configuration, the retraction 372 is formed at the rear of the leveling arm 370 and protrudes upward from the machine body, and the left and right leveling rotating bodies 371, 371 are arranged with a left and right gap therebetween. Thus, the seedlings planted in the planting hoppers 20a and 20b pass through the left and right spacers of the left and right leveling rotating bodies 371 and 371, and the soil around the seedlings is leveled and passes below the retreat portion 372, so that the soil-covered leveling wheels 37 and 37 are prevented from being pressed down and the planting posture is prevented from being disturbed.

The left and right leveling arms 370 and 370 are respectively mounted so as to be able to adjust the left and right positions of the machine body, and are configured so as to be able to change the positions to be leveled in accordance with the inter-row setting of the insertion hoppers 20a and 20 b. Further, the left and right leveling rotating bodies 371, 371 are configured to reliably fix soil around the planted seedlings when the left and right positions are adjustable, and prevent the seedlings from being fallen down or from being grown poorly at low temperatures.

In the transplanter of the present embodiment, an operation seat 46 is provided on which an operator sits so that the operator who supplies seedlings to the seedling supply device 43 carries out a seedling supply operation. Specifically, the work seat 46 is disposed rearward at the center of the right and left of the body, which is the front side of the seedling supply device 43. The operator sitting on the work seat 46 sits on the front side of the seedling supply device 43 in a posture facing the rear side, and performs the seedling supply work in correspondence with the front side of the seedling supply device 43, particularly the front linear portion in the circulating movement path of the seedling storage body 22.

Further, a main clutch lever 125 is provided on the other of the left and right sides of the steering panel 47a, and the main clutch lever 125 is incorporated in the transmission case 39 to connect/disconnect the transmission of the driving force to the left and right traveling transmission cases 38 and 26.

In the transplanter 10 of the present invention, when moving to a field, unloading from a transport unit, storing in a warehouse, and turning around at the end of the field, the operator operates the operating handle 404 at the rear of the machine body. On the other hand, in the transplanting operation of seedlings, it is difficult for an operator to get on the operation seat 46 of the traveling vehicle body 40 and operate the operation panel 47a of the operation handle 404.

Therefore, the traveling vehicle body 40 is provided with an on-vehicle body control unit 126 for the operator who gets on the work seat 46.

As shown in fig. 4 and 10, a rear step plate 127 inclined upward toward the rear side of the machine body is provided at a lower portion of the seedling supply device 43, and as shown in fig. 4, 5, and 10, a vehicle body upper control portion 126 is provided at either of the right and left sides of the rear step plate 127, in this case, at an end portion of the right side of the machine body (the left side based on an operator sitting on the work seat 46).

The vehicle body upper control unit 126 has a 2 nd vehicle height adjustment lever 128 disposed on the outermost body side, the 2 nd vehicle height adjustment lever 128 adjusts the vehicle height of the traveling vehicle body 40 to adjust the insertion depth of the insertion hoppers 20a, 20b, and a 2 nd main clutch lever 129 is disposed on the inner body side of the 2 nd vehicle height adjustment lever 128.

In addition, since there is substantially no need to fix the height during the transplanting operation of the seedlings, the 2 nd vehicle height adjusting lever 128 is constructed to have only the "high" position and the "low" position.

Further, a vehicle height adjusting lever guide having a display scale indicating a vehicle height standard is provided at an outer end of the rear pedal 127 in an inclined posture upward toward the front side of the machine body so that the 2 nd vehicle height adjusting lever 128 is converged in the frame, and a main clutch lever guide having the 2 nd main clutch lever 129 converged in the frame is provided at an inner side of the machine body in an inclined posture upward toward the front side of the machine body.

Further, the 2 nd vehicle height adjustment lever 128 projects toward the body front side by a larger amount than the 2 nd main clutch lever 129.

The ride height adjustment lever guide and the main clutch lever guide are disposed at a certain up-down interval from the upper surface of the side pedal 118. The vertical interval is set to a degree (for example, about 15cm to 20 cm) that a space can be secured even when the operator's foot is placed therein.

According to the above configuration, the operator riding on the floor pedal 122 and the work seat 46 can perform the manual operation of the transplanting depth and the manual operation of the connection/disconnection of the transplanting work without going down the traveling vehicle body 40, and therefore, the work efficiency is improved and the transplanting accuracy of the seedlings is improved.

Further, by disposing the 2 nd main clutch lever 129 inside the machine body closer to the work seat 46 than the 2 nd vehicle height adjustment lever 128, the hand of the operator can easily reach the 2 nd main clutch lever 129 used for the replenishment of seedlings, the correction of the transplanting state, the rest, and the like, and the labor can be reduced.

In particular, the transplanting work of the seedlings can be promptly interrupted when a problem occurs, the re-transplanting work of the seedlings is not required, and the number of the seedlings which are not suitable for growth and are discarded is reduced.

Further, by projecting the 2 nd vehicle height adjustment lever 128 further toward the front side of the machine body than the 2 nd main clutch lever 129, it is not necessary to largely project the arm when the 2 nd vehicle height adjustment lever 128 on the side away from the work seat 46 is operated, and the labor of the operator is reduced.

Further, by providing the right and left side clutch pedals at the rear pedal 127, when the traveling direction of the traveling vehicle body 40 deviates from the straight traveling direction based on the ridges, any one of the side clutch pedals is operated to temporarily set the corresponding side clutch in the off state, thereby correcting the traveling path of the traveling vehicle body 40 and preventing the transplanting position of the seedling from meandering in the right and left directions.

Further, since the vertical space is formed between the vehicle height adjustment lever guide and the main clutch lever guide, that is, the vertical space between the vehicle body upper operation portion 126 and the side step 118, the movement of the feet of the operator riding on the work seat 46 is not hindered, and the operator can ride on the work seat 46 in a comfortable posture, thereby reducing the labor.

In the side view of the machine body, a preliminary seedling rack 50 is provided above the transmission axles of the traveling members 44 on both the left and right sides of the working seat 46, and the preliminary seedling rack 50 can store seedlings to be supplied to the seedling supply device 43.

The prepared seedling rack 50 is configured such that a support member is provided on the upper part of a seedling support column 51 projecting to the outside of the body of the traveling vehicle body 40, a seedling placing rotating arm capable of switching between a rotating state and a non-rotating state is provided on the support member, a seedling rack frame in the vertical direction is disposed on the seedling placing rotating arm at intervals, one end part of a loading table 55 is mounted on the same surface of the seedling rack frame, and a container such as a seedling box or a seedling tray for accommodating a seedling for replenishment is placed on the loading table 55.

Only one of the tables 55 may be provided in the vertical direction, but a plurality of the tables 55 may be disposed at intervals in the vertical direction that do not hinder the removal of the container.

The prepared seedling racks 50 having the above-described structure are respectively provided on the left and right sides of the traveling vehicle body 40, and the seedling placing/rotating arms are rotated above the support members in accordance with the situation.

For example, in the case of transplanting a seedling, the longitudinal direction of the placing table 55 is directed in the front-rear direction of the machine body, so that it is easy to take out a container of the seedling from the placing table 55 and to replace the empty container, thereby improving the work efficiency.

Further, since the placement tables 55 are positioned on both the left and right sides of the traveling vehicle body 40 at this position, the operator can easily grasp the end portions of the riding portions of the traveling vehicle body 40, and prevent the feet from being exposed from the traveling vehicle body 40 and losing their posture.

When the operator rides in and out of the traveling vehicle body 40, the seedling placing/rotating arm is rotated by about 90 degrees.

Thus, a space for the passenger to land is formed on both the left and right sides of the traveling vehicle body 40.

Further, the operator can also take in and out from the front side of the traveling vehicle body 40, but when the seedling placing/rotating arm is rotated to bring the seedling frame to the front side of the machine body and the placing table 55 to the rear side of the machine body, the operator can use the seedling frame as the armrest, and therefore, the traveling vehicle body 40 can be smoothly taken in and out.

Further, when the container for seedlings is loaded or unloaded on the loading table 55, if the container is loaded or unloaded from the rear side of the machine body, there is no member that hinders the loading or unloading of the container, and therefore, the work efficiency is improved.

The work seat 46 is mounted to the traveling vehicle body 40 at an upper portion of a portion of the seat frame that is in the left-right direction of the machine body, and the seat frame straddles a machine body cover 48 that is コ -shaped in front view or rear view and covers the engine 41 and the like. The upper part of the seat frame is provided with base parts of left and right seat supports facing the front side of the body, and the work seat 46 is provided so as to be rotatable in the front-rear direction of the body about a rotation fulcrum in the left-right direction of the base parts of the left and right seat supports.

Thus, the work seat 46 can be placed in a state of contacting the vicinity of the front end of the body of the seedling supply device 43, and therefore, it is possible to prevent sand and rain water from adhering to the seating portion of the operator when the work is interrupted.
