JP 2009-82050 A (FIG. 1)

  In a paddle coater, the work implement body may be turned upward to temporarily enter a non-working state, and if left in this state, the soil adhering to the spray nozzle will harden and spread during the padding operation. There is a risk of clogging the nozzle.

  However, in the above-described paddy coater, when the spray nozzle is clogged with soil, the spray nozzle is disassembled to remove the soil, or the liquid spray amount can be adjusted manually by the setting operation means. It can only be adjusted to remove the soil. In such a case, every time the spray nozzle is clogged with soil, disassembly work and reassembly work are necessary, or after manually adjusting the liquid spray amount to the maximum, manually return to the desired liquid spray amount again. There is a problem that workability deteriorates, such as the need for such complicated work.

  The present invention has been made in view of these points, and an object of the present invention is to provide a coater capable of eliminating the clogging of the spray nozzle without reducing workability.

  The wrinkle coater according to claim 1 is a work machine main body having a wrinkle forming part, a spraying means having a spray nozzle for spraying liquid, a setting operation means for setting a spraying amount of liquid from the spraying means, And a control means for controlling the spraying means to adjust the spraying amount of the liquid. The control means controls the spraying means when it is determined that the liquid spraying start command has been received, and an adjustable range. After the liquid is sprayed for a predetermined time with the maximum spraying amount, the liquid is sprayed with the spraying amount set by the setting operation means.

  The wrinkle coater according to claim 2 is the wrinkle coater according to claim 1, wherein the work machine body is in a working state by one operation, and is in a non-working state by another operation different from the one operation, When it is determined that the work machine main body is in a non-working state, the control means controls the spraying means to automatically stop the liquid spraying, and determines that the work machine main body is in a working state from the non-working state. When it is determined that a command to start spraying the liquid is received in the state, the spraying means is controlled to spray the liquid for a predetermined time with the maximum spraying amount within the adjustable range, and then set by the setting operation means The liquid is sprayed at a spraying amount.

  According to the first aspect of the present invention, when it is determined that the liquid spray start command has been received, the control unit controls the spray unit to dispense the liquid with the maximum spray amount within the adjustable range for a predetermined time. Since spraying is performed automatically, it is possible to eliminate the clogging of the spray nozzle without degrading workability, and after eliminating this clogging, the liquid is sprayed with the set spray amount by the setting operation means. The amount of sprayed liquid can be adjusted.

  According to the second aspect of the present invention, the control means controls the spraying means when it is determined that the work implement main body has been in the working state from the non-working state and has received a liquid spraying start command. Because the liquid is sprayed for a predetermined time with the maximum spraying amount within the adjustable range, it is possible to effectively eliminate the clogging of the spray nozzle at a more appropriate timing, and it is judged that the work equipment body has become non-working In this case, since the spraying of the liquid is automatically stopped by controlling the spraying means, it is possible to prevent the spraying means from continuously spraying the liquid wastefully when the work machine body is not in a working state.

  Moreover, the glazing machine 1 sprays liquid toward the surface of the side surface forming body 28 and the surface of the upper surface forming body 29 of the heel forming means 22 in order to adjust the moisture content and prevent soil adhesion to the heel forming means 22. Dispersing means 31 is provided. The liquid is water, for example, but may be a liquid organic fertilizer or a liquid herbicide.

  As shown in FIGS. 1 to 4, the spraying means 31 includes a tank 32 that stores a liquid such as water, a pump 33 that sucks and discharges the liquid in the tank 32 to a high pressure, and an electric motor that operates the pump 33. An actuator 34 such as a motor, a pipe 35 such as a flexible pipe having one end connected to the pump 33 and the other end opposed to the flange forming means 22, and fixed to the other end of the pipe 35 A plurality of, for example, two spray nozzles 36 having the same shape are disposed behind the soot forming means 22 and spray the liquid flowing in the pipe 35 by the operation of the pump 33 toward the soot forming means 22.

  The tank 32 and the pipe 35 are supported by a support frame 38 fixed to the rotating machine frame 6. The pump 33 is, for example, a reciprocating pump such as a plunger pump or a piston pump, or a rotary pump such as a vane pump or a gear pump.

  One of the two spray nozzles 36, 36 is positioned opposite to the surface of the side surface forming body 28 of the ridge forming means 22 and sprays liquid toward the surface of the side surface forming body 28. The other spray nozzle 36 is positioned opposite to the surface of the upper surface forming body 29 of the ridge forming means 22 and sprays liquid toward the surface of the upper surface forming body 29. As shown in FIG. 1, one spray nozzle 36 is disposed at a position facing substantially the center of the rear end edge 28a along the direction inclined with respect to the left-right direction of the side surface forming body 28 in plan view, The other spray nozzle 36 is disposed at a position facing the substantially center of the rear edge 29a along the left-right direction of the upper surface forming body 29 in plan view.

  Further, the spreader 1 controls the setting operation means 41 for setting the spray amount of the liquid sprayed from the spray nozzle 36 and the actuator 34 of the spray means 31 according to the setting of the setting operation means 41 to control the liquid. And a control means 42 such as a controller for adjusting the spread rate.

  As shown in FIG. 4, the setting operation means 41 is an operation box connected to the control means 42 via a connection cord 43, for example, and is disposed at a position where an operator sitting on the driver's seat of the tractor can operate. . The setting operation means 41 has a box body 45 having a substantially rectangular shape when viewed from the front. The box body 45 has a power switching operation section which is a command input section such as a switch for switching power on and off. 46 and a lamp 47 that is turned on when the power is turned on are provided. The box main body 45 is provided with an operation speed setting operation section 48 such as an operation knob that can be rotated to set the operation speed (reciprocation speed, rotation speed, etc.) of the pump 33 by the actuator 34. The surface of the box main body 45 is provided with a scale such as a numeral for indicating the operating speed of the pump 33. The amount of liquid sprayed from the spray nozzle 36 can be adjusted steplessly by setting the operating speed setting operation unit 48 of the setting operation means 41.

  The control means 42 controls the actuator 34, for example, by PWM (Pulse Width Modulation), and operates the actuator 34 with a duty ratio for obtaining the operating speed set by the operating speed setting operation section 48 of the setting operation means 41. It is possible. Further, the control means 42 is based on, for example, a detection means 49 fixedly attached to the shaft portion 3 or the like of the machine frame 2 to determine whether the work machine body 10 is in the working state shown in FIG. It is possible to determine whether it is in a non-working state. Further, the control means 42 incorporates a timer (not shown) which is a time measuring means, for example. The timer may be provided outside the control means 42 and electrically connected to the control means 42, for example.

  The detecting means 49 is, for example, a potentiometer connected to the axis of the rotating arm 4 and sets the resistance value corresponding to the rotation angle α of the rotating arm 4 (rotating machine frame 6), thereby controlling the control means 42. However, the rotation angle of the work implement body 10 can be detected. The detection means 49 may be an angle sensor (tilt sensor), for example.

  The control means 42, the pump 33, and the actuator 34 are accommodated in an accommodation case 50 fixed to the rotating machine frame 6.

  Next, the operation and the like of the wrinkle coater 1 will be described with reference to the flowchart of FIG.

  By connecting the hull coater 1 to the three-point link hitch portion of the tractor and extending the rod 18 of the driving means 7 with respect to the cylinder body 17, that is, the right turn based on the extension of the driving means 7 (one Operation), the rotating machine frame 6 is rotated so as to protrude sideways with respect to the machine frame 2 through the rotating arms 4 and 4, and the work machine body 10 is put into a working state. The machine 1 is moved along the marshal.

  When the hammer coater 1 moves along the main fence, the cutting surface 26 of the embankment means 21 cuts the surface of the rice field and the front of the main fence, and the cut soil becomes the upper earth and is raised on the main fence. The forming means 22 is compacted by the side surface forming body 28 and the upper surface forming body 29 to form a new bag.

  During this smearing operation, the control means 42 determines whether or not the operator has operated the power switching operation section 46 of the setting operation means 41 to turn on the power (step 1). If it is determined that the power is not turned on, the loop of step 1 is repeated. If it is determined that the power is turned on (first start command), the process proceeds to the next step 2. Note that the lamp 47 is turned on simultaneously with the power-on.

  Subsequently, the control means 42 determines whether or not the work machine body 10 is in a working state due to the extension of the drive means 7 (step 2). This determination is made by the control means 42 determining based on the resistance value of the detection means 49 set corresponding to the rotation angle α of the rotation arm 4 (rotation machine frame 6). Here, when it is determined that the work machine body 10 is not in the working state, the loop of step 2 is repeated.

  When it is determined in step 2 that the work implement body 10 is in the working state (second start command), both the first start command and the second start command are input to the control means 42. The control means 42 can be adjusted regardless of the operating speed of the pump 33 set by the rotation operation of the operating speed setting operation part 48 of the setting operating means 41 The actuator 34 is operated by PWM control in a state where the maximum spraying amount within this range, here the duty ratio (on duty) is 100%, and the pump 33 is operated by this actuator 34. As a result, the liquid in the tank 32 flows through the pipe 35 and is ejected vigorously from the nozzle openings of the spray nozzles 36, thereby eliminating the clogging of the nozzle openings of the spray nozzles 36 (cleaning operation, step 3).

  When a predetermined time from the start of the cleaning operation to the time-up of the timer, for example, about 1 to 10 seconds, preferably about 3 to 5 seconds, the control means 42 sets the operating speed of the pump 33 of the spraying means 31. It is determined whether or not (step 4).

  For example, when liquid such as water is sprayed toward the surface side of the heel forming means 22 with the spraying means 31 in order to adjust the moisture content and prevent soil from adhering to the heel forming means 22, an operator sitting in the driver's seat of the tractor In the stopped state of the spraying means 31, the operating speed setting operation part 48 of the setting operation means 41 is rotated to set the operating speed of the pump 33 of the spraying means 31 according to the soil condition of the marshal. The operator can perform this setting operation at an arbitrary timing.

  When it is determined in step 4 that the operating speed is not set, in other words, the setting position of the operating speed setting operation unit 48 is 0, the control unit 42 controls the power switching operation unit of the setting operation unit 41. It is determined whether or not the power is turned off by the operation of 46 (step 5).

  In step 5, if the control means 42 determines that the power is not turned off, the process returns to step 4. If the control means 42 determines that the power is turned off, the lamp 47 is turned off and the control is terminated. .

  If it is determined in step 4 that the operation speed is set (the setting position of the operation speed setting operation unit 48 is not scale 0), the control means 42 operates the operation set by the operation speed setting operation unit 48. Actuator 34 (pump 33) is operated at a duty ratio for obtaining speed. When the pump 33 is operated, the liquid in the tank 32 flows through the pipe 35 and is discharged from the nozzle opening of the spray nozzle 36, and sprayed on the surface of the side surface forming body 28 and the surface of the top surface forming body 29 (step 6). The predetermined time for performing the cleaning operation may be set to a fixed value, for example, may be selected by a worker from a plurality of preset fixed values, or may be arbitrarily set by the worker. .

  In this state, the control means 42 determines whether or not the power is turned off (step 7). That is, when the operator operates the power switching operation unit 46 of the setting operation means 41 and turns off the power while the liquid is being sprayed, the lamp 47 is turned off and the actuator 34 and the pump 33 are stopped (step 8). Control ends.

  Even when it is determined that the power is not turned off, the control means 42 determines whether or not the work implement body 10 is in a non-working state (step 9). In Step 9, as in Step 2, the control means 42 makes a determination based on the resistance value of the detection means 49 set corresponding to the turning angle α of the turning arm 4 (rotating machine frame 6). Done. If it is determined that the work machine body 10 is not in the non-working state, that is, it is in the work state, the process returns to step 4, and if it is determined that the work machine body 10 is in the non-working state, the control means 42 is the actuator 34. (Pump) is controlled to automatically stop the spraying of liquid (Step 10), and the process returns to Step 2.

  That is, the wrinkling operation is temporarily interrupted, and the work machine main body 10 is rotated leftward based on the contraction of the driving means 7 (another operation different from the one operation) and the operation state shown in FIG. When entering the non-working state, no operation by the operator is required, that is, the control means 42 controls the actuator 34 even if the operator does not perform an operation such as an off operation of the power switching operation unit 46, for example. Control to automatically stop spraying liquid.

  Specifically, in step 10, the control means 42 is preset with a resistance value of the detection means 49 corresponding to the rotation angle α of the rotation arm 4 (rotation machine frame 6) accompanying the rotation of the work machine body 10. When the value is greater than or equal to or less than the predetermined angle (FIG. 2), the control means 42 determines that the work machine body 10 is not in a working state, that is, in a non-working state. The actuator 34 is controlled to automatically stop the operating pump 33. As a result, the spraying of the liquid from the spray nozzles 36, 36 of the spray means 31 is automatically interrupted.

  In addition, the work machine body 10 is returned to the working state in order to resume the drape work by the work machine body 10, and the rotation angle of the rotating arm 4 (rotating machine frame 6) accompanying the rotation of the work machine body 10. When the resistance value of the detection means 49 corresponding to α is equal to or less than a predetermined angle set in advance or greater than a predetermined angle (FIG. 1), the control means 42 is informed if the power supply switching operation section 46 remains on. Since a command to start spraying is input, the control means 42 controls the actuator 34 with a duty ratio (on duty) 100% and operates the pump 33 according to the determination in step 2. As a result, after the cleaning operation by spraying with the maximum spraying amount within the adjustable range of the liquid from the spraying nozzles 36, 36 of the spraying means 31 is performed for a predetermined time, it is set by the operating speed setting operation unit 48. The spraying of the liquid from the spray nozzles 36, 36 of the spraying means 31 is automatically restarted at a duty ratio for obtaining a high operating speed.

  As described above, according to the spreader 1, when the control means 42 determines that it has received a command to start spraying the liquid, the actuator 34 is controlled so that the liquid is predetermined with the maximum spray amount within the adjustable range. In order to perform the cleaning operation for spraying for a time, the spray nozzles 36, 36 are disassembled, the operation speed setting operation part 48 of the setting operation means 41 is manually operated, and the liquid is sprayed at the maximum spray amount for a certain period of time, etc. The clogging of the spray nozzles 36 and 36 can be eliminated without deteriorating workability. Therefore, for example, at the start of the wrinkling operation, after disassembling and reassembling the spray nozzles 36, 36, manually operating the operating speed setting operation unit 48 of the setting operation means 41, and once adjusting the maximum spray amount, Complicated work such as readjustment to a desired spraying amount is not required, and after completion of the cleaning operation for a predetermined time, the smearing work can be started immediately and work efficiency can be improved.

  In particular, at the start of spraying of liquid from the spray nozzles 36, 36 of the spraying means 31, time may have elapsed since the previous spraying of the liquid. Since the dirt adhering to the nozzle 36 may harden and the nozzle opening may become clogged, the cleaning operation for a predetermined time as described above enables efficient and reliable spraying of the liquid from the spray nozzles 36 and 36 after the cleaning operation. Can be done.

  In addition, after eliminating this clogging, the liquid is sprayed toward the surface of the side surface forming body 28 and the surface of the top surface forming body 29 of the heel forming means 22 with the amount of spraying set by the operating speed setting operation unit 48 of the setting operation means 41. By doing so, it is possible to adjust the amount of liquid sprayed from the spray nozzle 36 toward the surface of the side surface forming body 28 and the surface of the top surface forming body 29, so that, for example, the liquid in the tank 32 can be sprayed efficiently, and the capacity It is not necessary to use a large tank 32 having a large size.

  Further, the control means 42 controls the spraying means 31 to determine that the cleaning operation is performed when it is determined that the work implement main body 10 has received a command to start spraying the liquid in a state where it has been determined that the work machine body 10 has changed from the non-working state. Therefore, the clogging of the spray nozzle 36 can be effectively eliminated at a more appropriate timing.

  In other words, when forming the ridges, it may be necessary for the tractor to change the traveling direction with the work implement body 10 temporarily in a non-working state at the corners of the paddy surface or the like. In such a case, by temporarily stopping the spraying of the liquid from the nozzle opening of the spray nozzle 36, there is a possibility that the dirt or the like adhering to the nozzle opening will solidify and the nozzle opening will be clogged. Accordingly, when the working state is temporarily changed to the non-working state and then the working state is resumed, the clogging of the spray nozzle 36 can be more reliably eliminated by performing the cleaning work for a predetermined time.

  Moreover, when the work machine body 10 is in a non-working state, the side surfaces of the ridge forming means 22 are formed from the spraying means 31 without operating the operating speed setting operation section 48 or the power supply switching operation section 46 of the setting operation means 41. In order to automatically stop the spraying of the liquid toward the surface of the body 28 and the surface of the upper surface forming body 29, the surface of the side surface forming body 28 and the upper surface of the side surface forming body 22 when the working machine body 10 is not in operation. It is possible to appropriately prevent the liquid from being continuously sprayed unnecessarily toward the surface of the formed body 29. Therefore, for example, the water spraying is automatically stopped simply by setting the position of the work machine body 10 to the non-working state, so that water can be saved easily, and the number of times of water injection into the tank 32 during the dredging operation can be reduced. Furthermore, in this state, the water spraying automatically resumes after the cleaning operation just by setting the position of the work machine body 10 to the working state, so that the operator sets the operating speed of the pump 33 by the setting operation means 41 each time. The work efficiency can be further improved without requiring a work such as correcting or turning on the power again by the power supply switching operation unit 46.

  Further, by using a potentiometer or the like as the detection means 49, the detection means 49 can be easily installed without complicating the configuration of the coater 1 more than necessary or making a significant design change.

  Note that, as shown in FIGS. 6 and 7, for example, the coater 1 may be switched between a non-working state and a working state by rotating up and down.

  6 and 7 is a hydraulic mechanism that is provided at the rear end of a tractor body 57 having a front wheel (not shown) and a rear wheel 56 of a tractor 54 that is a traveling vehicle so as to be vertically rotatable. It is connected via a quick coupler 59 to a three-point link hitch portion (working device lifting / lowering support device) 58 that is actuated by (not shown) and pivots up and down. Further, the input shaft 15 of the glazing machine 1 is connected to the PTO shaft 60 of the tractor 54 by power transmission means (not shown).

  The three-point link hitch portion 58 has one top link 61 that can be expanded and contracted, and two lower links 62 and 62 in a pair of left and right.

  Then, the work implement main body 10 is brought into a substantially horizontal working state shown in FIG. 6 by the downward rotation based on the operation of the three-point link hitch portion 58, and the operation of the three-point link hitch portion 58 (work implement lifting operation). Based on the upward rotation based on this, a non-working state with a forward and downward inclined shape with respect to the front-rear horizontal direction shown in FIG.

  The rotating machine frame 6 is provided with a directional wheel 64 that can move up and down. Further, the upper portion of the side surface forming body 28 is covered with the disk cover 24 of the rotating machine frame 6 in the rotating machine frame 6.

  In addition, the brush coater 1 includes a detection unit 67 that detects an inclination angle β of the work machine body 10 with respect to the front-rear horizontal direction instead of the detection unit 49 of the above-described embodiment. The control means 42 connected to the control means controls the actuator 34 in accordance with the inclination angle β detected by the detection means 67.

  The detection means 67 is constituted by, for example, an inclination sensor or a potentiometer, and is fixedly attached to the side surface of the machine frame 2 of the work machine body 10.

  Note that the minimum inclination angle β with respect to the front-rear horizontal direction of the work machine body 10 when the work machine body 10 shown in FIG. 7 is in a non-working state is, for example, approximately 10 degrees. That is, the work machine body 10 enters a non-working state when the inclination angle β becomes approximately 10 degrees or more. Note that this inclination angle β is set according to the matching state between the tractor 54 and the coater 1, and may be over 10 degrees depending on the type of the tractor 54, for example, 15 degrees or 20 degrees. But you can. 6 and 7 is basically the same as that of the coater 1 shown in FIG. 1 and the like.

  6 and 7, the paintering work by the work machine body 10 is temporarily interrupted, and the work machine body 10 operates the three-point link hitch portion 58 of the tractor 54. When the working state shown in FIG. 6 is changed to the non-working state shown in FIG. 7 (for example, the state where the inclination angle β is approximately 10 degrees) due to the upward rotation based on this, the spraying means 31 requires any operation by the operator. In other words, for example, even if the operator does not operate an operation unit such as an operation button for stopping the spraying, the liquid is sprayed toward the surface of the side surface forming body 28 and the surface of the top surface forming body 29 of the wrinkle forming means 22 To stop automatically.

  That is, when the work machine body 10 is in the inclined non-working state shown in FIG. 7 (inclined non-working state having an inclination angle equal to or larger than the preset minimum inclination angle β), the work detected by the detection means 67 is detected. Based on the inclination angle β of the machine main body 10, the control means 42 determines that the work machine main body 10 is in a non-working state, and controls the actuator 34 by blocking the energization of the actuator 34 to automatically stop the operating pump 33. As a result, the spraying of the liquid from the spray nozzle 36 of the spraying means 31 is automatically interrupted.

  In addition, when the work machine main body 10 is returned to the working state for resuming the hulling work by the work machine main body 10, the work machine main body 10 is operated by the inclination angle β of the work machine main body 10 detected by the detection means 67. The control means 42 determines that the state has been reached and controls the actuator 34 with a duty ratio (on duty) of 100% to operate the pump 33. As a result, after the cleaning operation by spraying with the maximum spraying amount within the adjustable range of the liquid from the spraying nozzles 36, 36 of the spraying means 31 is performed for a predetermined time, it is set by the operating speed setting operation unit 48. The spraying of the liquid from the spray nozzles 36, 36 of the spraying means 31 is automatically restarted at a duty ratio for obtaining a high operating speed.

  6 and 7 can remove the clogging of the spray nozzles 36 and 36 without disassembling the spray nozzles 36 and 36 by spraying. No complicated disassembling and reassembling work of the spray nozzles 36, 36 is required at the start of the operation, and after the cleaning operation for a predetermined time is completed, the wrinkling process can be started immediately, and the work efficiency can be improved. The effects similar to those of the coater 1 shown in No. 1 can be obtained.

  In the embodiment shown in FIGS. 6 and 7, the attachment position of the detection means 67 can be any position where the inclination angle β of the work implement body 10 can be detected. For example, you may attach to the mast part 69 which is the standup | rising frame part of the machine frame 2 of the working machine main body 10 (imaginary line L1), or you may attach to the attachment frame (not shown) etc. which support the tank 32 ( Imaginary line L2).

  In each of the above embodiments, the configuration in which the spray nozzle 36 is fixed has been described. However, the liquid ejected from the spray nozzle 36 is substantially the entire surface of the side surface forming body 28 of the wrinkle forming means 22 and the top surface forming body 29. The spray nozzle 36 can be reciprocally rotated within a range of a certain angle (for example, 10 to 360 degrees) with respect to the wrinkle forming means 22 so as to be distributed over substantially the entire surface. It may be configured to be swingable, that is, swingable. In this swinging operation, the rotation speed of the spray nozzle 36 may be arbitrarily set (changed), and it may be configured so that the operator can select whether to reciprocate or not. 33 may be operated continuously or intermittently, and the operation time of the pump 33 may be arbitrarily set (changed). Further, the spray nozzle 36 is not reciprocally rotated, and the spray nozzle 36 may be linearly reciprocated along the surface of the side surface forming body 28 or the surface of the upper surface forming body 29. Accordingly, during the cleaning operation, if the clogging of the nozzle opening of the spray nozzle 36 can be eliminated, for example, the liquid sprayed from the spray nozzle 36 is directed toward the surface of the side surface forming body 28 or the surface of the top surface forming body 29 of the ridge forming means 22. It does not have to be.

  On the other hand, the spraying means 31 is not limited to the configuration having the pump 33 and the actuator 34 for operating the pump 33. For example, the nozzle opening of the spraying nozzle 36 is connected to the control means 42 and controlled by the control means 42. A configuration having an actuator such as an electric motor that varies the opening amount of the motor may be used. That is, for example, when the spray amount is small, the liquid is discharged from the nozzle opening with a small diffusion angle, and when the spray amount is large, the liquid is discharged from the nozzle opening with a large diffusion angle.

  A pumping means such as a pump that pumps the liquid in the tank 32 toward the spray nozzle 36 when the power is turned on may be provided so that the liquid can be discharged from the nozzle opening with a desired discharge pressure.

  Furthermore, in any embodiment, the number of the spray nozzles 36 of the spray means 31 is arbitrary, and may be one or three or more.

  Further, the configuration is not limited to a configuration in which the amount of sprayed liquid can be adjusted steplessly by the setting of the setting operation means 41, and the adjustment may be stepped.

  Further, the above embodiments can be combined as appropriate. For example, when the work machine main body 10 can be turned left and right and up and down, the control means 42 determines that the work machine main body 10 is in the working state based on the detection means 49 and 67, that is, the detection means. It is configured to permit the spraying of the liquid from the spraying means 31 only when the rightward rotation of the work machine body 10 is detected by 49 and the downward rotation of the work machine body 10 is detected by the detection means 67. Thus, the same operational effects as those of the above embodiments can be obtained.

  As a configuration for putting the work implement main body 10 into a working state or a non-working state, it is possible to apply a configuration that allows arbitrary different operations other than the configuration in which the work implement main body 10 is rotated.

  Further, when the operation speed setting operation unit 48 is set to the scale 0, it is possible to control so as not to perform the cleaning operation. The configuration in which the amount of liquid sprayed from the spray nozzle 36 cannot be set to 0 (there is no scale 0), that is, the liquid is always sprayed from the spraying means 31 when the power is turned on by the power switching operation unit 46. You can also. In this case, since the processes in steps 4 and 5 are not necessary, the control can be further simplified.

  Furthermore, the spraying means 31 is configured to spray the liquid toward the wrinkle forming means 22. For example, the spraying means 31 is configured to spray the liquid only toward the front porridge of the wrinkle forming means 22, or A configuration in which the liquid is sprayed toward any position, such as a configuration in which the liquid is sprayed toward each of the scissors, that is, a configuration in which the liquid is sprayed toward at least one of the scissors forming means 22 and the main scissors. .
