Description

  The present invention relates to a canopy structure for a riding transplanter that supports a canopy on a canopy support and covers an upper portion of a control unit.

  Conventionally, on the canopy support that is erected on the side of the bonnet and between the auxiliary seedling stand, the front part of the canopy is provided in a cantilevered state by a rotation support part, and the driving work posture covers the upper part of the control part. A transplanter capable of switching to a retracted posture in which the rear portion of the canopy is rotated downward is already known as disclosed in Patent Document 1.

This canopy structure is provided with a canopy rotation support portion, which is configured at the upper part of the canopy support column, at a position higher than the head position of the operator seated on the seat, and the canopy from the driving work posture with the rotation support portion as a fulcrum For maintenance work such as replenishing seedlings to the planting device performed by the operator standing up on the deck section and switching to the standing work position by rotating the canopy upward and changing the posture in the extension direction of the canopy post. ing.
JP 2001-224208 A

  However, as shown in Patent Document 1, the canopy that rotates only the roof portion that covers the upper portion of the control unit rotates around the rotation support portion provided at the high position of the long canopy post to change the posture. Therefore, when carrying out the seedling operation to move to the front step to replenish seedlings and take out the mat seedling from the auxiliary seedling mounting stand, even if the canopy is rotated upward and switched to the standing work position, the long canopy post There is a drawback that the shoulders and arms of the worker touch the upper part. Also, when moving the front side step, the canopy struts are moved over the narrow front side step with a limited width, and the operation is accompanied by an unreasonable operation such as twisting the body. There are problems such as lowering.

  In addition, when the canopy is changed to the retracted posture, the retractable posture cannot be lowered because the rotation support portion is high, and the canopy is easily blown by the wind when the transplanter is loaded on the vehicle and transported. is there.

  In order to solve the above-mentioned problem, the canopy structure for a passenger transplanter of the present invention firstly has a bonnet 5 and a control unit 6 covering the engine and the like at the front part of the traveling machine body 4, and the control unit 6 is disposed above the control unit 6. In the transplanting machine in which the covering canopy 2 is provided on the canopy support column 30 erected on the side of the bonnet 5 on the front side of the control unit 6 so that the posture can be changed via the rotation support unit 31, the rotation support unit of the canopy 2 31 is provided at substantially the same height on the front side of the steering handle 12 installed in the control unit 6, a driving work posture in which the canopy 2 covers the upper part of the control unit 6, a retracted posture for tilting backward, and a seedling for tilting forward It is characterized in that it can be switched to the next posture.

  Secondly, the canopy 2 is connected to the roof portion 21 and the front window 22 and formed in an inverted L shape in a side view, and the support is provided behind the roof portion 21 and the front window 22 with a support interval. The stay 25 is connected to the lower part of the front window 22 and the rear part of the roof part 21.

  As described above, according to the present invention, the storage position of the canopy is lowered because the canopy is moved from the driving posture to the retracted posture with the pivot support portion provided at substantially the same height on the front side of the steering handle as a fulcrum. The machine can be stored and stored easily. In addition, canopy by wind can be regulated. Further, when the canopy is tilted forward from the rotation support portion and switched to the seedling posture, the canopy support column does not protrude high above the steering handle 12, so that the space above and above the control portion can be widened. It is possible to easily perform seedling operations and the like.

  The canopy, which has an auxiliary stay that connects the roof and the front window and has a support interval behind it, has a canopy that forms an inverted L shape in side view and reinforces the auxiliary stay in the bending direction. The entire structure can be made rigid by the support, and cantilever support to the canopy support column having high stability can be achieved. The auxiliary stay can also be used as a handle for rotating the canopy, and the canopy posture can be easily changed.

  An embodiment of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes a riding type transplanter equipped with a canopy 2. A traveling machine body 4 having a front wheel 3 and a rear wheel 3 a is equipped with an engine (not shown) at the front portion and a bonnet 5 together with a fuel tank. The steering part 6 is arranged behind the bonnet 5, auxiliary seedling platforms 7 and 7 are installed on both sides of the bonnet 5 in front of the steering part 6, and a lifting link mechanism 9 hydraulically operated at the rear part of the body is provided. The planting device 10 is supported so as to be movable up and down.

The planting device 10 includes a seedling platform 10a for placing five mat mat seedlings, each planting claw 10b for scraping and planting seedlings from the seedling platform 10a, and a plurality of floats 10c that are grounded at the time of planting. Etc.
The control unit 6 includes a deck unit 11 formed in a flat shape in the middle of the traveling machine body 4, a steering handle 12 disposed in front of the deck unit 11, and a rear seat 13. Is installed at the upper part of the seat frame that is erected at the rear center of the deck portion 11 and covered with the cover 15.

The deck portion 11 has a front side step 16 and a rear side step 17 on a flat surface that can be walked and moved along the outer sides of the bonnet 5 and the cover 15, respectively.
Further, the auxiliary seedling placing table 7 on which the replenishing mat seedlings are placed in a plurality of stages is constituted by a support column erected from the traveling machine body 4 outside the left and right front side steps 16.

  In the transplanter 1 as described above, the canopy 2 that covers the upper part of the operator seated on the seat 13 has a driving work posture, a retracted posture, and a seedling by a canopy structure that is configured on the front side of the control unit 6 and has a rotation mechanism. It is configured to be switchable to three different postures.

That is, the canopy 2 includes a canopy frame 20 provided so that its posture can be switched via a rotation support portion 31 of a canopy support 30 (to be described later), a awning roof portion 21 supported by the canopy frame 20, and a front made of a transparent member. It consists of a window 22 and the like.
Both the roof portion 21 and the front window 22 in the illustrated example are made of a synthetic resin material, and are manufactured in a shape having rigidity by a cross section having a gently curved surface. Further, the canopy 2 is formed in an inverted L shape in a side view by integrally assembling and connecting the lower side of the front portion of the roof portion 21 and the upper side of the front window 22.

The canopy frame 20 is connected to the left and right mounting brackets 23, 23 made of plate members rotatably supported on the canopy support column 30 in a state where the canopy frame 20 is mounted and fixed on both lower sides of the front window 22. The connecting frame 20a is used for reinforcement.
The mounting brackets 23, 23 are attached and fixed to the base end portion of the auxiliary stay 25 provided at a predetermined support interval along the shape of the roof portion 21 and the front window 22 behind the canopy 2.

  The auxiliary stay 25 that stands up from the mounting bracket 23 bends with the upper part extending behind the front window 22 close to the inverted L-shaped bent part of the canopy 2, and below the roof part 21. The rear end portion extended and bent inward with a support interval is attached and fixed to a mounting seat 26 formed on the rear side rear portion of the roof portion 21.

  With this configuration, the entire canopy can be formed into a rigid structure by the rigidity of the canopy itself having an inverted L-shape on the front side of the control unit 6 and the reinforcement support of the auxiliary stay 25 in the bending (bending) direction. Sufficient strength of the canopy 2 supported in a cantilever shape on the upper portion and support stability with improved vibration isolation are improved.

  That is, the canopy 2 connects the roof portion 21 having a curved cross section and the front window 22 to increase the panel rigidity, and the auxiliary stay 25 maintains a predetermined support interval with respect to the front window 22 and the roof portion 21. The lower part and the rear part are connected to the mounting bracket 23 and the mounting seat 26 to increase the rigidity in the bending direction.

  Also, sufficient rigidity against vibration and impact when switching to a retracted posture that tilts backward from the driving work posture and a seedling posture that tilts forward from the driving work posture via a rotation mechanism described later And toughness of the canopy 2 can be prevented.

In addition, since the auxiliary stay 25 is installed close to the back along the canopy shape, the auxiliary stay 25 is installed without narrowing the control space with the seat 13 side. It does not get in the way when the operator gets on and off the control unit 6.
Further, when the maintenance work such as the correction of the seedling position of the auxiliary seedling placing stand 7 is performed in the leaning posture from the seat 13 side with the canopy 2 switched to the seedling posture, the auxiliary stay 25 and the canopy column 30 do not interfere with the work. .

  Furthermore, when performing the above-mentioned three-way posture change of the canopy 2, the auxiliary stay 25 that is extended along with a support interval for reinforcement behind the front window 22 can be used by any worker of different heights. Since an arbitrary position can be easily grasped by extending a hand, the auxiliary stay 25 can be used as a handle. In addition, since a special handle can be omitted, there is an advantage that the canopy structure can be simplified.

  The shape and size of the canopy 2 configured as described above is such that the front window 22 is formed so as to be able to stand on the front side of the steering handle 12 and the rear portion of the roof portion 21 covers the seat 13. In the posture, the rear portion of the roof portion 21 penetrates deeply into the space formed between the seat 13 and the seedling table 4 so as to be stored compactly.

  Accordingly, when the canopy 2 is changed to the retracted posture, the bent portion can be brought close to or supported by the seat 13 and the rear portion can enter the space portion to reduce the canopy retractable height as much as possible. Therefore, the transplanter 1 can be easily stored and stored, canopy caused by strong winds can be avoided outdoors, and the steering handle 12 and the seat 13 can be reliably protected from rain.

  Furthermore, the canopy 2 when changed to the seedling posture is configured to switch and support the rear end of the canopy 2 above or slightly forward of the steering handle 12 as shown by the phantom line in FIG. When the worker stands up as it is from the sitting posture, the contact between the head and body and the canopy 2 is prevented. At this time, since the canopy 2 is not largely rotated to the front side at the above-described rotation position, the canopy structure can be simplified and the weight can be reduced without excessively supporting the canopy support 30. .

  In addition, the width of the canopy 2 is controlled to be substantially the same width as the bonnet 5 or slightly wider so that when the canopy 2 is changed to the seedling posture, the front window 22 is largely restricted to protrude above the front step 16 on both sides. Then, the mat seedling is taken out from the auxiliary seedling placing stand 7 and the seedling placing stand 4 of the planting device 10 is replenished with seedlings.

  For this reason, as will be described later, the canopy support column 30 has a vertical support part 31 that forms an upper part of the rotation support part 31 that pivotally supports the canopy 2 provided on the upper part, and is close to the bonnet 5, and the lower part of the vertical support part part. Is bent in a substantially U-shape toward the outside, and is fixedly attached to the side wall of the traveling machine body 4 in a detour state close to the front step 16. Further, upper portions of the left and right canopy columns 30, 30 having a substantially bonnet width are connected and reinforced by a horizontal frame 32.

  In addition, the canopy 2 attaches and fixes an auxiliary window piece 35 made of a transparent transparent plate along the lower side of the front window 22, and brings the lower end of the auxiliary window piece 35 close to the upper shape of the bonnet 5 so that the connection The front side of the frame 20a is covered. Since the auxiliary window piece 35 has flexibility, it does not hinder the opening / closing operation of the bonnet 5 or the fuel tank portion cover of the bonnet 5. The wiper 36 for cleaning the surface of the front window 22 is driven by a wiper motor 37 attached to and supported by the connecting frame 20a behind the auxiliary window piece 35 through the auxiliary window piece 35. .

  Next, the support structure of the canopy 2 will be described with reference to FIGS. As described above, the front step 16 is detoured in a U-shape from the machine body side, and the canopy columns 30, 30 erected on the rear side of the bonnet 5 are provided with the support shaft 50 projecting from the upper portion thereof, and the canopy frame 20. Are inserted into mounting holes 51 formed in the mounting brackets 23, 23 to constitute the rotation support portion 31 of the canopy 2. The rotation support portion 31 is installed at substantially the same height on the front side of the steering handle 12. That is, the rotation support portion 31 in the illustrated example is located above the bonnet 5 and below the upper end portion of the steering handle 12 and above the lower end portion of the front window 22.

  The horizontal frame 32 for connecting the left and right canopy columns 30 and 30 with a substantially bonnet width is a ring-shaped attachment member 55 which is erected from the machine body side and fitted and fixed to a handle column 53 which supports the handle shaft 52 inside. By connecting with the stay 56, the support rigidity is enhanced by reinforcing the canopy columns 30, 30 in the front-rear and left-right directions.

  In addition, as shown in FIG. 4, the turning mechanism for switching the canopy 2 so that the posture can be changed is provided with engagement grooves 57, 58, 59 corresponding to the respective posture positions of the canopy 2 in one mounting bracket 23. And an operation member 60 that is biased and supported on the canopy column 30 side so as to be able to switch from the non-locking position to the locking position so as to be able to be switched to the engaging grooves 57, 58, 59. It has become.

  That is, when the operating member 60 is locked to the engaging groove 59 by the switching operation from the driving work position of the canopy 2 in which the operating member 60 is locked to the engaging groove 57 as shown in FIG. The canopy 2 can be switched to the retracted position and supported by being locked in the engaging groove 58.

  As described above, the transplanter 1 having the canopy structure configured to be able to switch the canopy 2 to the driving work posture, the retracted posture, and the seedling posture, performs the transplanting operation in a state where the canopy 2 is in the driving work posture, When the seedling operation is performed with the machine stopped, the operator extends one hand with the rotating mechanism released and holds the arbitrary position of the auxiliary stay 25 and pushes it forward before standing up from the seat 13. Then, the canopy 2 can be tilted to the front side with the rotation support portion 31 as a fulcrum and can be easily switched and supported in the seedling posture.

  In this seedling posture, the canopy support column 30 that is formed short so that the rotation support portion 31 of the canopy 2 is positioned in the vicinity of the front side of the steering handle 12 can be seen from the front window 22 side that also serves as the front frame member. Since the canopy column 30 does not protrude high above the steering handle 12 at this time, the space above and ahead of the steering unit 6, that is, the front space, can be widened, and the canopy column 30 and Without being disturbed by the canopy 2, it is possible to efficiently and easily perform the seedling work and the maintenance work of the auxiliary seedling stage 7 and the like.

Further, when the canopy 2 is switched to the retracted posture, the roof portion 21 is tilted from the side of the rotation support portion 31 toward the space between the seat 13 and the planting device 10, so that the retractable height of the canopy 2 is increased. Can be lowered.
In addition, although the canopy 2 of this embodiment demonstrated the structure which connected and formed the roof part 21 and the front window 22, when not providing only the roof part 21 without providing the front window 22, it is not limited to this. Instead of the front window 22, a mounting frame can be erected from both sides of the canopy frame 20, and the front left and right sides of the roof portion 21 can be connected to the upper part of the mounting frame.

It is a side view of the riding transplanter provided with the canopy structure of the present invention. It is a top view of FIG. It is a front view which abbreviate | omits and shows the half of a canopy structure. It is a perspective view which abbreviate | omits and shows a canopy structure partially.
