DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the drawings, embodiments of the present invention and embodiments of inventions related to the present invention will be described in detail.

[0018] The same applies below, but some components may not be shown in the drawings, or may be shown in a perspective or simplified manner.

[0019] (1) First, the configuration and operation of a work system according to an embodiment of the present invention will be specifically described with reference to FIG. 1 and FIGS. 2(a) to 2(c).

[0020] Here, Figure 1 is a left side view of a working system of an embodiment of the present invention, Figure 2(a) is a schematic partial oblique view (part 1) of the vicinity of a guide agent storage hopper 1210 of a ridge former 1000 of an embodiment of the present invention, Figure 2(b) is a schematic partial rear view (part 1) of the vicinity of a guide agent storage hopper 1210 of a ridge former 1000 of an embodiment of the present invention, and Figure 2(c) is a schematic partial plan view (part 1) of the vicinity of a guide agent storage hopper 1210 of a ridge former 1000 of an embodiment of the present invention.

[0021] The work system of this embodiment has a ridge former 1000 and a work machine 2000.

[0022] The ridge forming machine 1000 has a ridge forming device 1100 that forms the ridges 3000, and a guide agent spraying device 1200 that sprays a guide agent 4000 onto the ridges 3000 formed by the ridge forming device 1100.

[0023] For example, the ridge forming device 1100 is a ridge forming device attached to the traveling vehicle body of a ridge forming machine 1000 such as a walk-behind cultivator that tills the soil and forms ridges 3000 suitable for transplanting work, and the guide agent spraying device 1200 as a line drawing agent sprayer is a guide agent spraying device that sprays a guide agent 4000, which is a line drawing powder as a transplant guide agent that can be absorbed by the soil, such as fertilizer mixed with slaked lime, iron powder, and colored powder, onto the ridges 3000 formed by the ridge forming device 1100. While the vehicle body of the ridge forming machine 1000 travels using running wheels that contact the field surface 3200, the guide agent 4000 is sprayed so that a following line is formed for the traveling vehicle body of the work machine 2000 to follow on the ridge surface 3100 of the ridge 3000.

[0024] The guide agent storage hopper 1210 as a line drawing agent hopper is attached to the upper surface of the main body of the ridge forming device 1100 by utilizing a plate 1210p for mounting the hopper. A chute section 1210s for discharging the agent is provided on the front surface of the main body of the guide agent storage hopper 1210. An internal observation window 1210w is provided on the front part of the upper surface of the main body of the guide agent storage hopper 1210, and a lid 1210c which is an opening and closing lid for adding the agent is provided on the rear part of the upper surface of the main body of the guide agent storage hopper 1210.

[0025] The working machine 2000 has a guide agent detection device 2100 that detects the guide agent 4000 sprayed by the guide agent spraying device 1200, and a working device 2200 that performs a predetermined task based on the detection of the guide agent 4000 performed by the guide agent detection device 2100.

[0026] For example, a guide agent detection device 2100 such as a magnetic tracking sensor or a camera tracking sensor is a guide sensor attached to the running body of a work machine 2000 such as a transplanter, which detects a transplant guide agent, and the work machine 2200 is a transplanting machine that performs planting work of seedlings in a ridge 3000 onto which a guide agent 4000 has been sprayed as a transplant guide agent.

[0027] An alarm device may be provided that operates to notify the outside by sound or the like when the spraying of the guiding agent 4000 is not detected by the guiding agent detection device even though planting work is being performed.

[0028] The guide agent 4000 sprayed on the ridges 3000 is detected by the guide agent detection device 2100 to determine whether the vehicle is traveling in a location suitable for planting, thereby preventing the planting position of the seedlings from shifting significantly in the left-right direction of the vehicle, thereby improving planting accuracy. The guide agent 4000 is a transplant guide agent that contains components that can be absorbed by the soil, so not only does it support the growth of the seedlings, but it also eliminates the need for the labor required for the task of removing the guide agent 4000.

[0029] The guide agent spraying device 1200 has a guide agent storage hopper 1210 provided above the ridge forming device 1100 for storing the guide agent 4000 to be sprayed. The guide agent storage hopper 1210 has a guide agent feed port 1211. The guide agent feed port 1211 is located behind the ridge forming device 1100 in the front-rear direction of the vehicle body.

[0030] The guide agent spraying device 1200 functions as a discharge device that discharges the guide agent 4000 from a guide agent storage hopper 1210, such as a storage hopper for the guide agent 4000 as a transplant guide agent, to the ridge 3000. The guide agent storage hopper 1210 is disposed at the top of the ridge forming device 1100, and the position of the guide agent delivery port 1211, which serves as a discharge port for the guide agent 4000, is located toward the rear of the vehicle body compared to the ridge forming device 1100.

[0031] Since the guide agent storage hopper 1210 is provided above the ridge forming device 1100, the spraying position of the guide agent 4000 is less likely to deviate from the ridge 3000, and the guide agent 4000 as a transplant guide agent is sprayed in a straight line suitable for transplanting seedlings, etc.

[0032] A lid is provided on the lime outlet so that the lime does not spill when not in use, and a specification may be adopted in which the pins on the upper side of the box and the pins on the lower side are used to hook the notches in the lid onto the pins on the upper side and fix the lid when opened by using two pins on the upper side and a spring attached between the pins on the lower side and the lid. The degree of opening may be adjusted by providing multiple pins on the upper side.

[0033] A ridge forming device 1100 attached to the traveling vehicle body tills the soil to form ridges 3000, while a guide agent spraying device 1200 sprays a guide agent 4000 onto the ridges 3000.This provides a configuration for an efficient ridge forming and transplanting work method in which, if the guide agent 4000 is detected by a guide agent detection device 2100 provided on a work machine 2000 such as a transplanter, seedlings are planted, but if the guide agent 4000 is not detected, an alarm device is activated and seedlings are not planted.

[0034] When the ridge making work is performed, a guide agent 4000 such as a transplanting guide agent is simultaneously sprayed, so that a separate work for forming a planting work guide for the work machine 2000 in the ridge is not required, which promotes reduction in work time and work labor. By performing transplanting work in which the work machine 2000 follows behind the vehicle body to which the ridge making device 1100 is attached, work efficiency is improved.

[0035] By combining the cultivator's ridge-making function with the transplanter's automatic tracking function, which automatically follows the shape of the ridges drawn in the center of the ridge with lime or other materials while distinguishing the difference between the color of the line drawn in the center of the ridge and the color of the soil, a cheaper configuration can be realized compared to a fully automatic configuration using a rice transplanter's straight-line mechanism or GPS mechanism, without the need for additional components such as a GPS device.

[0036] (2) Next, the configuration and operation of the work system according to the embodiment of the present invention will be described in more detail with reference mainly to FIGS. 3(a) to 3(f).

[0037] Here, Figure 3(a) is a schematic partial oblique view (part 2) of the vicinity of the guide agent storage hopper 1210 of the ridge former 1000 of an embodiment of the present invention, Figures 3(b) and 3(c) are schematic partial rear views (parts 2 and 3) of the vicinity of the guide agent storage hopper 1210 of the ridge former 1000 of an embodiment of the present invention, Figure 3(d) is a schematic partial plan view (part 2) of the vicinity of the guide agent storage hopper 1210 of the ridge former 1000 of an embodiment of the present invention, Figure 3(e) is a schematic partial left side view of the vicinity of the guide agent storage hopper 1210 of the ridge former 1000 of an embodiment of the present invention, and Figure 3(f) is a schematic partial rear view of the vicinity of the bevel gear case 1215c of the ridge former 1000 of an embodiment of the present invention.

[0038] FIG. 3(b) shows a state in which the guide agent supplying port shutter 1212 is closed, and FIG. 3(c) shows a state in which the guide agent supplying port shutter 1212 is open.

[0039] The guide agent storage hopper 1210 has a guide agent delivery rotating brush 1213 provided near a guide agent delivery port 1211. The guide agent delivery rotating brush 1213 is rotated so as to deliver the stored guide agent 4000 from the guide agent delivery port 1211 by utilizing the rotation of a ground contact roller 1213w that rotates with the vehicle body traveling.

[0040] For example, the guide agent delivery rotating brush 1213 is an annular brush attached to a rotating brush shaft arranged on the lower side of the guide agent storage hopper 1210 of the guide agent spraying device 1200 rotatably mounted on the rear hitch 1500 at the rear of the vehicle body. The guide agent 4000 is delivered to the ridge 3000 by the rotation of the ground contact roller 1213w by the ground contact reaction force.

[0041] The stay 1214 for fixing the shutter is a stay for mounting the guide agent delivery port shutter 1212 whose base is attached to the left side surface of the main body of the guide agent storage hopper 1210.

[0042] The rotation of the ground contact roller 1213w is input to the pay-out roll input shaft 1215, which is supported by a pay-out roll bearing 1215b provided on the side of the main body in the left-right direction of the vehicle, via an input bevel gear 1215i and an output bevel gear 1215o stored inside a bevel gear case 1215c.

[0043] Of course, the rotation direction of the feed roll input shaft 1215, which is the rotation direction of the guide agent feed rotating brush 1213, is counterclockwise when viewed from the left side, and the guide agent 4000 is fed rearward as the vehicle travels forward.

[0044] With regard to the delivery roll configuration, a portion of the cylindrical brush outer surface of the guide agent delivery rotating brush 1213 always comes into contact with the inner bottom of the guide agent storage hopper 1210, but to prevent the guide agent 4000 from being pressed too strongly against the inner bottom of the guide agent storage hopper 1210 and to ensure smooth delivery of the agent to the chute section 1210s, brush bristles or a sponge or the like are attached to the outer surface of the cylindrical brush, and it is desirable that the contact of the guide agent delivery rotating brush 1213 with the hopper is made only by the elastic portion of the outer surface of the cylindrical brush.

[0045] The angle of the guide agent storage hopper 1210 is freely adjustable, and the contact roller 1213w is grounded on the ridge surface of the ridge 3000 at a height where the driven rotation is easily performed, so the contact roller 1213w does not crush the ridge surface with ground pressure, and grooves caused by the crushing of the ridge surface, which can have a negative effect on crop growth, are hardly formed. The contact roller 1213w is grounded firmly enough, so uneven distribution of the guide agent 4000 is unlikely to occur. By rotating the guide agent delivery rotating brush 1213, which functions as a brush of the guide agent spraying device 1200, which is a release device of the guide agent 4000, by the driven rotation of the contact roller 1213w, not only is the guide agent 4000 supplied to the ridge surface of the ridge 3000 at a predetermined set amount as the vehicle body advances, but a transmission structure for rotating the contact roller 1213w is not necessary, which promotes simplification of the structure.

[0046] As shown in Figures 4(a) to 4(c), the degree of contact of the contact roller 1213w with the ground may be adjusted by adjusting the inclination of the guide agent storage hopper 1210 relative to the ridge forming device 1100.

[0047] Here, Figs. 4(a) to 4(c) are partial left side views (parts 1 to 3) in the vicinity of a ridge former 1000 of a working system according to a first modified embodiment of the present invention.

[0048] Figure 4(a) shows a state in which the remaining drug level of guide agent 4000 is large, Figure 4(b) shows a state in which the remaining drug level of guide agent 4000 is medium, and Figure 4(c) shows a state in which the remaining drug level of guide agent 4000 is small.

[0049] A hopper up-down rotation mechanism is realized by mounting the bottom plate of the guide agent storage hopper 1210 to the rear hitch 1500 of the traveling vehicle body from above with a pin. That is, a hopper push-up spring mechanism 1210b having a plurality of springs arranged side by side in the vehicle body front-rear direction between the ridge forming device 1100 and the guide agent spraying device 1200 as a drug spraying device, which have different spring lengths, is connected by inserting a bent pin of metal or hard rubber of the hopper locking pin mechanism 1210e into the rear hitch 1500. The spring of the hopper push-up spring mechanism 1210b is pushed down by the weight of the drug present inside the guide agent storage hopper 1210 as a drug hopper, and as the drug decreases, the front side of the traveling vehicle body is pushed up by the spring force and spring length.

[0050] Of course, in order to change the hopper inclination according to the weight of the drug, a hopper lifting spring mechanism 1210b is arranged in the vertical gap between the ridge forming device 1100 and the mounting plate of the guide agent storage hopper 1210, and the hitch attachment of the guide agent storage hopper 1210 is performed using a hopper locking pin mechanism 1210e having a metal pin or rubber rod pin or the like having a certain degree of flexibility or deformation elasticity, so that the drug is less likely to accumulate near the front side of the running body of the guide agent storage hopper 1210, and there is no need for the troublesome manual work of scooping out the drug or tilting the hopper.

[0051] It goes without saying that the hopper inclination angle adjustment mechanism may, for example, be provided as an angle adjustment mechanism between the running body of the ridge forming machine 1000 and the rear hitch 1500, or may be provided as an angle adjustment mechanism between the rear hitch 1500 and the ridge forming device 1100, or may be provided as an angle adjustment mechanism between the ridge forming device 1100 and the guide agent spraying device 1200.

[0052] An attachment axis in the left-right direction of the vehicle body is provided at a bent portion formed by bending the left and right ends of the front side of the mounting plate of the guide agent spraying device 1200 downwardly relative to the vehicle body, and a configuration may be adopted in which the attachment angle to such an attachment axis is adjusted by tightening a bolt or the like.

[0053] As shown in Figure 5, which is a left side view of a work system of a second modified embodiment of the present invention, a specification may be adopted in which lime is scraped out only during operation by connecting a brush provided near the lime outlet, the rotating shaft of the ridge forming machine, a belt 1216 for transmitting the guide agent, which is covered by a belt cover 1216c, and a pulley, together with a sight glass provided near the lime outlet of the lid provided on the top of the box for storing lime.

[0054] For example, the ground contact wheel 1213w may be a driven ground contact wheel arranged on the end of a rotating brush shaft that protrudes outside the guide agent storage hopper 1210 in the left-right direction of the vehicle body, and contacts the ridge 3000 laterally compared to the spraying position of the guide agent 4000.

[0055] In a configuration in which the brush rotates and scrapes out the lime by connecting with tires attached to the side of a box for storing lime, which rotates as the vehicle moves, a specification may be adopted in which a box attached to the top of the ridge forming machine is fixed to the rear hitch of the cultivator with a pin and a push bolt.

[0056] In a configuration in which the inclination of a box for storing lime can be adjusted on top of the rear hitch of the mounting part, a specification may be adopted in which a brush shaft of a brush provided near the lime outlet of the box protrudes from the side of the box and a tire is provided on the brush shaft. A plurality of holes may be provided on the brush shaft so that the tire provided on the side of the box does not hit the ridges, and the brush width may be adjusted by pinning with the plurality of holes.

[0057] The guide agent storage hopper 1210 has a guide agent supply port shutter 1212 provided near the guide agent supply port 1211. The guide agent supply port shutter 1212 is a downward-opening shutter whose sliding direction is the vertical direction, and is locked in an open state at a predetermined angle by using a pin 1212p inserted into one of a plurality of pin holes 1212b formed side by side in the vertical direction.

[0058] That is, the guide agent dispensing port shutter 1212 is mounted so as to be movable in the vertical direction, and a plurality of pin holes 1212b aligned in the vertical direction are formed in a stay 1214 serving as a shutter fixing stay provided on the guide agent storage hopper 1210. When a pin 1212p, which is a positioning pin for shutter positioning operation, is inserted into one of the pin holes 1212b of the stay 1214, the guide agent dispensing port 1211 is firmly locked with the opening degree set.

[0059] As shown in Figures 6(a) to 6(f), the cable 1212c having one end connected to the pin 1212p may be operated, and the pin 1212p inserted into the pin hole 1212b may be pulled out from the pin hole 1212b, thereby closing the guide agent supply port shutter 1212.

[0060] Here, Figures 6(a) and 6(b) are schematic partial rear views (parts 1 and 2) of the vicinity of the guide agent storage hopper 1210 of a ridge former 1000 according to a third modified embodiment of the present invention, Figures 6(c) and 6(d) are schematic partial left side views (parts 1 and 2) of the vicinity of the guide agent storage hopper 1210 of a ridge former 1000 according to a third modified embodiment of the present invention, and Figures 6(e) and 6(f) are schematic partial left side views (parts 1 and 2) of the vicinity of pin 1212p of a ridge former 1000 according to a third modified embodiment of the present invention.

[0061] Figure 6(a) shows the guide agent supply port shutter 1212 in a closed state, Figure 6(b) shows the guide agent supply port shutter 1212 in an open state, Figures 6(c) and (e) show the pin 1212p inserted into the pin hole 1212b, and Figures 6(d) and (f) show the pin 1212p removed from the pin hole 1212b.

[0062] For example, the pin 1212p is an adjustment pin, such as a push bolt, which is a so-called tool-less member, inserted into the pin hole 1212b, and the cable 1212c, which is a wire for the pin removal operation, is a cable connected to an operating handle used for operating the vehicle body as a shutter opening / closing cable for inserting and removing the pin 1212p. When the cable 1212c is operated, the guide agent delivery port shutter 1212 rotates in a direction in which the amount of the guide agent 4000 to be sprayed decreases, that is, in a direction in which the guide agent delivery port 1211 is blocked.

[0063] The stay 1217s for rod connection attachment is a stay for attaching the rod 1217 for shutter positioning operation to the guide agent delivery port shutter 1212, the middle part of which is attached to the right side surface of the main body of the guide agent storage hopper 1210 via a rotating body 1217r for the rod support slide.

[0064] In this way, not only is the guide agent supply port shutter 1212 closed by the pin 1212p inserted into the pin hole 1212b being pulled out from the pin hole 1212b by operating the cable 1212c, but a configuration can also be realized in which manual operation is performed to adjust the opening degree of the shutter plate of the guide agent supply port shutter 1212 by rotating the rod 1217 in the vertical direction at a position away from the guide agent supply port shutter 1212, such as at the control unit position.

[0065] Arm 1218, which is a rotating arm for supporting a pin, has a left end portion rotatably attached to stay 1214, and is an arm for supporting pin 1212p.

[0066] The pin fixing portion 1219f of the pin 1212p is slidably fixed to the arm 1218, and the pin moving portion 1219t is pushed forward by the pin pushing spring 1219s, so that the pin 1212p is inserted into the pin hole 1212b. When the pin moving portion 1219t is moved rearward by the cable 1212c, the pin 1212p is pulled out of the pin hole 1212b. When the pin gripping portion 1219k is pulled by the fingers so that the pin moving portion 1219t is moved rearward together with the pin fixing portion 1219f, the pin 1212p is also pulled out of the pin hole 1212b.

[0067] The amount of the guide agent 4000, such as a transplant guide agent, sprayed is adjusted exactly according to the opening amount of the guide agent outlet shutter 1212, so that the guide agent 4000 can be stably detected by the guide agent detection device 2100, and a decrease in the accuracy of planting seedlings is suppressed. For example, since excessive supply of the guide agent 4000 hardly occurs, not only is the material cost of the guide agent 4000 reduced, but poor crop growth due to excessive supply of fertilizer components is also suppressed.

[0068] For example, the guide agent dispensing port shutter 1212 may be a shutter that is arranged on the lower side of the guide agent storage hopper 1210 and is freely rotatable around a rotation axis, for switching between introducing and removing the guide agent 4000 and adjusting the amount of guide agent 4000 released, and the pin hole 1212b may be a plurality of holes formed in an arc shape on the side surface of the lower side of the guide agent storage hopper 1210 as shutter opening adjustment holes that fix the guide agent dispensing port shutter 1212 at a predetermined rotation angle.

[0069] In a configuration in which a plate with multiple pin holes is provided on the side of the box and the degree of opening of the lid that blocks the lime outlet can be adjusted depending on the position of the pin hole into which the pin is inserted, the pin may be inserted and removed using a lever provided near the handle, or the lever provided near the handle may be pulled toward the user, and the lid may be raised and lowered by raising and lowering the handle for raising and lowering the lid.

[0070] (3) Next, the configuration and operation of the working system according to the embodiment of the invention related to the present invention will be specifically described with reference mainly to FIGS.

[0071] Here, Figures 7 to 9 are schematic partial oblique views (parts 1 to 3) of the vicinity of the first part 5100, the second part 5200, the third part 5300 and the fourth part 5400 of the ridge former 1000 in an embodiment of the invention related to the present invention.

[0072] A configuration using a ridger 1000 such as a tiller with a USB port is conceivable.

[0073] In this type of configuration, for example, a small USB-equipped fan attached to the handle and having a USB port for charging attached to the switch stay is driven by utilizing the battery of a ridger 1000, such as a tiller, that is equipped with a self-starting engine.

[0074] The battery installed is a 12V battery, and is not used for anything other than starting the engine. Such batteries can be widely used for emergency charging of various devices in fields where there is no power supply facility.

[0075] For example, in tillers that do not have cabins, the airflow from an electric fan can be used to improve the working environment, and the new application value of such batteries will increase as electric tillers become more widespread in the future.

[0076] The first part 5100 is provided with not only a hole for the passage of the second part 5200 but also a pin for the passage of the fourth part 5400 .

[0077] One side surface of the second component 5200 is configured as a flat surface, so that a so-called semi-cylindrical shape is adopted.

[0078] The third part 5300 is provided with not only a hole for inserting the round bar of the second part 5200 but also a hole for fixing the second part 5200.

[0079] The third part 5300 is provided with a claw-shaped notch that serves as a claw for fixing the electric fan.

[0080] The fourth part 5400 is provided with holes for the insertion of the pins of the first part 5100 as well as a number of pins for fixing the pins of the second part 5200 thereto.

[0081] (4) Next, the configuration and operation of the working system according to the embodiment of the invention related to the present invention will be described in more detail with reference mainly to FIGS.

[0082] Here, Figures 10 and 11 are explanatory diagrams (parts 1 and 2) of the vicinity of the loop handle 6000 of the working machine 2000 in an embodiment of the invention related to the present invention, and Figures 12(a) to 12(f) are explanatory diagrams (parts 1 to 6) of the vicinity of the operation panel 6100 of the working machine 2000 in an embodiment of the invention related to the present invention.

[0083] The loop handle 6000, which functions as an operating handle, and the parts related to maneuvering the machine provided around it will be described. As shown in Fig. 10 and Fig. 11, which show the main part of the operating handle and its surrounding configuration as a side view and a plan view, the loop handle 6000, which is U-shaped in a plan view and can be positioned by rotating either the front or rear of the work machine 2000, is provided, and the operating protrusion of the engine switch 6200 without a cover is obliquely intersecting with the fore-and-aft direction of the machine when it is stopped. Here, as shown in Fig. 1, 4 and 5, the loop handle 6000 faces the front of the machine.

[0084] A rod 6410, which functions as a fulcrum rod for a main clutch lever 6400, is connected to the lower portion of one of the left and right sides of the loop handle 6000 by welding or the like, and an engine switch 6200 that determines whether or not the engine is started by operating a recoil starter (not shown), and an operation panel 6100 that functions as an attachment panel for providing the main clutch lever 6400 that operates the main clutch in a transmission case (not shown) that switches on and off the travel transmission and the work transmission are attached to the inside of the machine body of the rod 6410. Furthermore, the rod 6410 serves as a rotation fulcrum for the main clutch lever 6400.

[0085] One end of a wire 6420 that functions as a main clutch on / off wire is connected to the lower end of the main clutch lever 6400, and the other end of the wire 6420 is connected to the main clutch, and the main clutch is switched on / off by operating the main clutch lever 6400 in the forward / rearward direction. In addition, a deadman lever 6500 is provided on a walk-behind working machine such as a tiller in order to switch the main clutch to a disengaged state in a shorter time than it takes to reach the main clutch lever 6400 from the loop handle 6000. The deadman lever 6500 is disposed in a space inside the loop handle 6000 in a U-shaped position in a plan view, and the grip part is normally retracted to a position separated upward from the loop handle 6000. A spring stay 6520 is provided on the lower end side of the deadman lever 6500, and a spring 6510 that functions as a linking spring for the deadman lever 6500 is provided between the spring stay 6520 and the limit switch 6300 near the engine switch 6200.

[0086] When it becomes necessary to quickly stop the machine, the operator rotates downward the deadman lever 6500, which is located closer to the loop handle 6000 than the main clutch lever 6400. This causes the spring stay 6520 to rotate upward, loosening the spring 6510 and rotating the limit switch 6300. As a result, the main clutch lever 6400 moves to the OFF position, or the engine switch 6200 moves to the OFF position, or both are switched over, cutting off the supply of driving force and stopping the movement of the work machine 2000 and the operation of the work device 2200.

[0087] Engine switch 6200 is provided via a torque spring (not shown), and is configured so that an operator can switch from position P as the off position, which is the stop position of the hole protrusion, to position Q as the on position, by pressing in and rotating the switch by a predetermined amount before the engine starts. When operating from position Q as the on position to position P as the off position, the biasing force of the torque spring can be used, so that engine switch 6200 can be switched by rotating in the opposite direction without pressing in, or by striking engine switch 6200.

[0088] As shown in Fig. 12(a) and 12(b), which show the orientations of the starter switch in the stopped state and the non-stop state as plan views of the main parts, the mounting hole 6211 of the engine switch 6200 is formed to be oblique with respect to the longitudinal direction of the vehicle body in the stopped state. An operation protrusion on the upper part of the engine switch 6200 is passed through the mounting hole 6211, and the engine switch 6200 is attached to the operation panel 6100 by a screw or the like via a mounting plate 6210. When the engine switch 6200 is rotated in a direction in which it assumes a posture that is substantially parallel to the longitudinal direction of the vehicle body, that is, when it is rotated clockwise in Fig. 12(a) and 12(b), it switches to position Q, which is an ON position that allows the engine to be started by the recoil starter.

[0089] With the configuration of this main configuration example, position Q, which is the ON position at which engine starting is permitted, can be set to a position where the operating protrusion of the engine switch 6200 faces in a linear forward / backward direction, making it easier for an operator to grasp the operating state of the engine switch 6200.

[0090] On the other hand, as shown in Fig. 12(c) and 12(d) which show the orientations of the stopped state and the non-stop state of another configuration example of the starter switch as a plan view of the main part, the mounting hole 6211 of the engine switch 6200 is formed to face the fore-and-aft direction of the vehicle body in the stopped state. An operation protrusion on the upper part of the engine switch 6200 is passed through the mounting hole 6211, and the engine switch 6200 is attached to the operation panel 6100 by a screw or the like via a mounting plate 6210. When the engine switch 6200 is rotated in a direction in which it is inclined with respect to the fore-and-aft direction of the vehicle body as a reference, that is, when it is rotated counterclockwise in Fig. 12(c) and 12(d), it switches to position P as an ON position that allows the engine to be started by the recoil starter.

[0091] With this alternative configuration example, when the engine switch 6200 is inserted into the mounting hole 6211, the mounting plate 6210 and the operation panel 6100 can be screwed together, making the assembly easy. In addition, the state in which the operation protrusion of the engine switch 6200 faces in the fore-and-aft direction of the machine body provides the assembly position, preventing assembly errors.

[0092] 12(e) and 12(f), which show the bending of the mounting panel for the starter switch as a cross-sectional view of the main part, when viewed from the front or rear, both left and right sides of the mounting plate 6210 each have a panel bent portion formed toward the bottom of the machine body as indicated by two arrows in order to retract from the inner surface of the operation panel 6100. The panel bent portion on the outside of the machine body has a gentler bending angle than the inside of the machine body, and is configured to cover the upper part of the limit switch 6300.

[0093] This allows a compact configuration to be maintained even when limit switches 6300 and the like are disposed. [Industrial Applicability]
