Description

The present invention relates to a working machine that is mounted on a traveling machine body and performs a predetermined work while proceeding with traveling of the traveling machine body. In particular, the present invention relates to a remote controller for remotely operating such a work machine.

Conventionally, in order to reduce the working hours of farm work, automatic work machines have been promoted, and various work machines have been developed. In particular, a work machine that is mounted on the rear of a traveling machine body such as a tractor and can be exchanged according to the type of work can be used for various farming operations by simply replacing the traveling machine body such as a tractor as an attachment. It is possible and greatly contributes to the cost reduction of farm work.

Among such working machines, there is known an offset working machine that works at positions that are separated (offset) in the side surface direction with respect to the running position of the running machine body. Known offset working machines include a hull coater and a mower. In particular, the wrinkle coater is an automated work for forming a wrinkle on the outer edge of the field, and has been developed in recent years as a work machine that can reduce a great deal of time and labor.

The wrinkle coater is mounted on the rear part of the traveling machine body, and includes a mounting part having an input shaft to which power from the traveling machine body is input, a power transmission mechanism that transmits power from the input shaft to the work machine, and support of the working part And a working unit that performs a smearing operation using the transmitted power. The working unit is composed of a pre-processing unit that cuts a part of an old paddle and deposits the earth, and a trimming unit that applies the piled soil to the cut old paddle.

When the amount of cutting and filling of the old paddy by the pre-processing unit changes, the amount of soil supplied from the pre-processing unit decreases and the nest is formed on the slope of the new paddle. In some cases, the amount of soil becomes excessive and the soil protrudes from the cylindrical portion provided at the center of the trimming portion, so that it is not possible to form a beautiful cage.

Therefore, in order to adjust the amount of soil supplied to the old paddle by the pre-processing unit, the pre-processing unit is provided so that the pre-processing unit can move up and down with respect to the machine body, A wrinkle coater that is movable in the vertical direction has been developed.

In addition, as a means of changing the relative height between the pretreatment unit and the trimming unit, by using a hydraulic cylinder instead of manually, an operator can get off the traveling machine body and set the relative height between the pretreatment unit and the trimming unit. There has also been developed a plastering machine that allows the operator to remotely control the expansion and contraction of the hydraulic cylinder while the operator is on the traveling machine without any adjustment. For example, in a remote control device for a glazing machine, when a remote operation switch of the device is operated, a corresponding actuator is operated, so that a working unit can be remotely operated from a driver's seat of a traveling machine body or the like.

However, even in such a paddy coater, the operator adjusts the optimum amount of soil supply while checking the actual state of new paddy formation and the current relative height between the pretreatment unit and the trimming unit. It is necessary to adjust the operation of the hydraulic cylinder.

Even if the operator does not get off the traveling machine body to confirm the formation status of the new car and the current relative height between the pre-processing unit and the trimming unit, the worker can see it while riding on the traveling machine body. Agricultural work machines having a display device that displays the relative heights of the pre-processing unit and the trimming unit of the work machine have also been developed (see Patent Document 1).

In addition, the dimensional ratio in the drawing may be different from the actual ratio for convenience of explanation, or a part of the configuration may be omitted from the drawing.

<Overall configuration>
FIG. 1 is an explanatory diagram showing the overall configuration of the glazing machine according to the present embodiment. The hull coater 100 includes a mounting unit 110 that is mounted on a link mechanism (for example, a three-point link mechanism) of the traveling machine body 190, a working unit 120 that performs a smearing operation, and a connecting unit that connects the mounting unit 110 and the working unit 120. 130 as a basic configuration. These basic configurations constitute the body of the hull coater 100.

The mounting unit 110 includes an input shaft (not shown) connected to the PTO shaft of the traveling machine body 190 via a transmission joint such as a universal joint, and the power transmitted to the input shaft is connected to the connecting unit. A mechanism for transmitting to 130 transmission mechanisms is also provided in the support member 113.

One end of the connecting portion 130 is supported by the support member 113 of the mounting portion 110 and the other end is attached to the working portion 120, and includes a link member 131 and an offset frame 132.

The link member 131 is a member whose one end is rotatably supported on the mounting portion 110 side and the other end is rotatably supported on the working portion 120 side, and controls the position of the working portion 120.

The offset frame 132 includes a winding transmission means for transmitting power to the working unit 120 side, and has transmission shafts 132a and 132b provided vertically, so that the offset frame 132 can be rotated around the transmission shaft 132a. The working unit 120 is supported so as to be rotatable around the transmission shaft 132b.

The offset frame 132 and the link member 131 are arranged in parallel, and these and the support member 123 form a parallel link mechanism. For this reason, the working direction of the working unit 120 does not change with respect to the swing of the connecting unit 130 in the offset angle θ direction, that is, the working unit 120 can be offset while maintaining the work surface with the tan coating.

In this embodiment, a parallel link mechanism is employed to facilitate control of an offset cylinder 140 and a direction cylinder 141, which will be described later. However, as an embodiment of the present invention, the offset cylinder 140 and the direction cylinder 141 are independent. In the case of an embodiment in which such a parallel link mechanism is not formed, the same control as described below is possible.

The working unit 120 forms a new paddle by applying a pre-processing unit 121 that cuts a part of an old paddle and performing a filling work, and applying the soil piled forward by the pre-processing unit 121 to the cut out old paddle. Are arranged in a support case (not shown), and the chain case 204 which is a part of the working unit 120 receives the power transmitted to the transmission shaft 132b as a pre-processing unit. A transmission mechanism that distributes between 121 and the trimming unit 122 is incorporated. The chain case 204 is connected to an electric hydraulic cylinder as an actuator 201 for rotating the chain case 204 in the vertical direction.

Here, the pretreatment unit 121 can employ a rotary tillage type pretreatment mechanism in which a rotary claw is mounted on a drive shaft, and a heaven treatment mechanism (top) that scrapes off the old cocoon heaven (upper surface) as necessary. A field processing rotor) may be added. The trimming unit 122 may employ a trimming drum including a cylindrical drum 122a that molds the upper surface of the rod and a conical umbrella-shaped drum 122b that molds the side surface of the rod.

The plastering machine 100 having such a basic configuration includes an offset cylinder 140 as a work position adjusting mechanism for adjusting the work position (offset position) of the work unit 120, and the work direction (rotation direction) of the work unit 120. ) And a direction cylinder 141 as a work direction adjusting mechanism.

In addition, an angle sensor 150 is provided as work direction detection means for detecting the work direction of the work unit 120. The angle sensor 150 does not detect a change in the direction of the working unit 120 relative to the connecting unit 130, but detects a change in the working direction with respect to the field scene of the working unit 120 alone, for example, a gyro sensor or the like. Can be adopted. In the present embodiment, the angle sensor 150 is disposed around the transmission shaft 132 b in the offset frame 132.

Further, a position sensor 151 is provided as a work position detecting means for detecting the work position of the trimming unit 122. The position sensor 151 is disposed behind the cylindrical drum 122a through a mounting arm 152 from a support case (not shown).

As shown in FIG. 2, the position sensor 151 has a built-in potentiometer for detecting the rotational displacement of the rotating shaft, and one end of a sensor rod 151a is fixed to the rotating shaft. The sensor rod 151a is a rod-shaped member whose sensitivity can be adjusted by adjusting the length. A contact portion 151b is formed at the tip of the sensor rod 151a, and the contact portion 151b is urged to be in contact with the side surface of a new rod. Has been. Then, when the sensor rod 151a is swung to the a side shown in FIG. 2 with respect to the reference position, the adjusting section 122 has moved to the left in the traveling direction with respect to the reference (the direction in which the adjusting section 122 is away from the heel). When the sensor rod 151a is swung to the b side shown in the figure, it is detected that the trimming unit 122 has moved to the right in the traveling direction (the direction in which the trimming unit 122 approaches the kite) with respect to the reference.

FIG. 3 is a diagram showing a configuration for adjusting the relative heights of the pretreatment unit and the trimming unit of the coater according to the embodiment of the present invention. As shown in FIG. 1, the trimming unit 122 includes a conical umbrella-shaped drum 122b attached to a rotation center shaft (not shown) that extends in the left-right direction with respect to the traveling direction of the traveling machine body and is rotatably supported. The cylindrical drum 122a is attached to the right end of the conical umbrella-shaped drum 122b and extends in the lateral direction. In addition, 206a and 206b shown in FIG. 3 respectively have the trimming unit 122 when the relative position of the trimming unit with respect to the preprocessing unit is the highest and when the relative position of the trimming unit with respect to the preprocessing unit is the lowest. Shows the rotation trajectory.

Referring to FIG. 3, the trimming unit 122 is configured to be interlocked with the chain case 204, and an electric hydraulic cylinder is connected to the chain case 204 as an actuator 201 for rotating the chain case 204 in the vertical direction. ing. One end 201b on the tip side of the rod 201a of the hydraulic cylinder that is the actuator 201 is pivotally mounted on a bracket 203 extending from the chain case, and the other end 201c of the hydraulic cylinder that is the actuator 201 is the main body of the coater. It is linked to the side (machine frame). For this reason, when the hydraulic cylinder, which is the actuator 201, is operated to expand and contract the rod, the chain case 204 rotates about the rotation center 208, and the rotation center 207 of the trimming section 122 rotates up and down to adjust. The height of the collar part 122 can be changed. Expansion and contraction of the hydraulic cylinder, which is the actuator 201, is controlled by a control unit 211 described later. Details of the control unit 211 will be described later.

In addition, the wrinkle coater 100 includes a height sensor 205. The height sensor 205 measures the rotational state of the trimming unit 122 by the actuator 201, and a rotational angle sensor or the like is applied to measure the relative position of the trimming unit 122 with respect to the preprocessing unit 121. . Specifically, a potentiometer may be used as the height sensor, and this may be installed in the vicinity of the rotation portion of the chain case with respect to the machine frame, and the rotation state of the chain case may be measured. Then, from the measured information, the control unit 211 may calculate the relative position of the trimming unit 122 with respect to the preprocessing unit 121 and display the height of the trimming unit 122 on the height display unit 187.

Referring to FIG. 3, a potentiometer for detecting the rotational displacement of the rotary shaft and a potentiometer arm are attached to the machine frame as a height sensor 205, and the potentiometer arm extends from a bracket 203 extending from the chain case 204 to the potentiometer side. Is slidably contacted with a pin (not shown) protruding from the surface. Thereby, when the vertical operation of the trimming unit 122 is performed, the chain case 204 is interlocked and rotated up and down, and the arm of the potentiometer rotates in response to the movement of the bracket 203 extending from the chain case 204. The signal is sent to the control box 210, the signal processed in the control box 210 is sent to the remote controller 180, and the remote controller 180 turns on a lamp that displays the height corresponding to the received signal.

Next, the control unit 211 that moves the trimming unit 122 in the vertical direction with respect to the preprocessing unit 121 will be described. FIG. 4 is a block diagram of a control unit mounted on the drape coater according to the embodiment of the present invention. The control unit 211 is disposed on the coater 100 and operates by receiving electric power supplied from the traveling machine body 190. Note that the control unit 211 may include an internal power source such as a battery, and may be operated with power from the internal power source. The control unit 211 is configured by storing necessary devices or the like in the control box 210, for example. Further, the control unit 211 may be integrally disposed in the control device 160 mounted on the remote controller 180 of the coater 100, and a control means for display may be provided separately. Moreover, you may have a recording means as needed.

As shown in FIGS. 3 and 4, the control unit 211 includes a height sensor 205, an up / down operation switch 188 (including an upper switch 188 a and a lower switch 188 b), a height display unit 187, and an electric motor that is an actuator 201. The hydraulic cylinder is electrically connected. The control unit 211 displays the current relative height of the trimming unit 122 relative to the preprocessing unit 121 on the height display unit 187 in accordance with the detection value of the potentiometer that is the height sensor 205.

The control unit 211 converts the detected value of the potentiometer, which is the height sensor 205, into a voltage value, compares the converted voltage value with a preset reference voltage value, and performs a display operation on the height display unit 187. Control. Specifically, if the voltage value sent from the potentiometer is, for example, “0 or more and less than 1 volt”, the control unit 211 turns on the lamp 187e at the bottom of the height display unit 187, and “1 or more and less than 2 volts”. Then, the second lamp 187d from the bottom is turned on. If it is "2 or more and less than 3 volts", the third (standard position) lamp 187c is turned on. If "3 or more and less than 4 volts", the fourth lamp 187b is turned on. If “4 or more and less than 5 volts”, the fifth lamp 187a may be controlled to be lit.

The up / down operation switch 188 includes an “up” switch 188a that is operated when the amount of soil supplied to the trimming unit 122 is larger than the current level, and the amount of soil supplied to the leveling unit 122 is larger than the current level. And a “down” switch 188b which is operated when the number is reduced.

When the “up” switch 188a is pressed, the control unit 211 is configured so that the position of the lower end of the conical umbrella-shaped drum 122b of the trimming unit 122 becomes higher than the current position, as shown by the rotation track 206a in FIG. The rod 201a is expanded and contracted steplessly by supplying an electric current to the electric hydraulic cylinder that is the actuator 201 for the pressed time, and the adjusting unit 122 is moved in the vertical direction with respect to the preprocessing unit 121. As a result, the relative positions in the vertical direction between the lower end of the trimming unit 122 and the lower end of the pretreatment unit 121 approach each other, the plowing depth by the pretreatment unit 121 increases, and the pretreatment unit 121 supplies to the trimming unit 122. You can increase the amount of soil that is played.

In addition, when the “down” switch 188b is pressed, the control unit 211 causes the position of the lower end of the conical umbrella-shaped drum 122b of the trimming unit 122 to become lower than the current position, as indicated by the rotation track 206b of FIG. In addition, the rod 201a is expanded and contracted steplessly by passing an electric current through the electric hydraulic cylinder that is the actuator 201 for the pressed time, and the adjusting unit 122 is moved in the vertical direction with respect to the preprocessing unit 121. As a result, the relative positions in the vertical direction between the lower end of the trimming unit 122 and the lower end of the pretreatment unit 121 are separated from each other, and the tilling depth by the pretreatment unit 121 is reduced and supplied from the pretreatment unit 121 to the trimming unit 122. The amount of soil that is played can be reduced.

As shown in FIG. 1, the plastering machine 100 configured in this way receives a detection value from the angle sensor 150, a detection value from the position sensor 151, and a detection value from a posture sensor 153 described later to the remote controller 180. Sent. Further, as shown in FIGS. 3 and 4, the detected value from the height sensor 205 is also transmitted to the remote controller 180. The detection value of each sensor may be transmitted to the remote controller 180 by wired communication or may be transmitted by wireless communication. Expansion / contraction control of the offset cylinder 140 and the direction cylinder 141 is performed based on detection values from the angle sensor 150 and the position sensor 151. The expansion / contraction control of the actuator 201 is performed based on the detection value from the height sensor 205.
