Description

  The present invention relates to a seedling transplanter.

  The seedling transplanting machine described in Patent Document 1 is for planting seedlings loaded in a seedling placement tank on a field with a seedling transplanting device, and moves forward and backward by operation of a traveling operation lever and by operation of a sub-transmission operation lever. It is possible to switch the running state to “road form”, “planting form”, and “neutral form”. When the driving state is in the “planting mode”, the power from the engine is distributed to both the driving transmission system and the planting transmission system, and a constant planting interval is maintained regardless of the driving speed level of the driving control lever. The seedling planting device will plant seedlings while holding.

JP 2012-205504 A

That is, since traveling power is not transmitted, the traveling vehicle body 2 is not driven back and forth, and only the seedling planting portion is driven.

In FIG. 10, the control block diagram of the seedling transplanter concerning this embodiment is shown. The control device 100 detects an operation detection member 101 that detects that the auxiliary transmission operation member 16 has been operated to the “pita planting” position, and a ground contact with respect to any of the field scenes of the center float 55 or the side floats 56 and 56. A ground contact detection member 102 that performs a deceleration operation detection member 103 that detects a deceleration operation of a deceleration operation member that decelerates the traveling vehicle body 2, and a rise detection member 104 that detects that the seedling planting device 4 has moved beyond a predetermined height. And the planting on / off member 105 for turning on / off the planting clutch mechanisms 112 and 115, and when each member is in the detection state, the control device 100 receives the signal and Perform the control described.
If the planting on / off member 105 is configured by an actuator such as an electric motor or a hydraulic cylinder, the control device 100 can easily perform switching control.

FIG. 11 shows an operation flow diagram of the first control of the seedling transplanter of this embodiment, and FIG. 12 shows an operation flow diagram of a set of steps in the operation flow diagram of FIG. Hereinafter, a set of steps is described as T01, and in the case of operation flows having the same contents, the same notation is used. FIG. 12 shows details of the step set T02, and the step set T04 exists in T02.
In the present embodiment, when the operation detection member 101 is in the detection state as the first control, the transmission of the driving force is cut off, the planting clutch mechanisms 112 and 115 are set to the “on” state, and the first set in advance. The seedling planting rod 52 is operated for a set time. And after this 1st setting time passes, when the detection state of the operation detection member 101 is located only for 2nd setting time, it is set as the structure which the seedling planting rod 52 act | operates again. Here, the first set time is a time required for the seedling planting pot 52 to rotate once or half, and the second set time is, for example, 3 to 5 after the operation detection member 101 is first in the detection state. About seconds.
Note that the times such as the first set time and the second set time are measured by a program or the like provided with the timer 200 in the control device 100 or incorporated as the timer 200.

  When the operation detection member 101 is in a detection state, the notification member 201 that sounds the buzzer 201a or blinks the center mascot 201b is activated. Thus, the operator knows that the operation detection member 101 is in the detection state. Can be easily recognized. In particular, it is desirable to change the state during rotation of the seedling planting basket 52 during the first set time and during continuous operation after the second set time has elapsed. Specifically, when the seedling planting basket 52 rotates during the first set time, when the operation detection member 101 is in the detection state, the buzzer will sound a short beep at an interval of about 1 second. The center mascot 201b makes the green and red lamps blink simultaneously at the same interval as the buzzer. When the first set time elapses and the seedling planting pot 52 stops, a long beep is sounded for about 2 seconds. At this time, the center mascot 201b is lit with a green lamp, and only the “planting lamp” is lit on the control panel 33. During continuous operation after the second set time has elapsed, the lamp of the center mascot 201b blinks green and red alternately and changes the interval of the buzzer 201a.

  When the operation detection member 101 is in the detection state, the traveling vehicle 2 is moved by interrupting the transmission of the traveling driving force and setting the planting clutch mechanisms 112 and 115 to the “on” state and operating the seedling planting rod 52. Therefore, it is possible to plant seedlings in a place where it is necessary to plant a single plant on the spot without moving. Thereby, the location where the seedling planting interval becomes too wide does not occur, and the field can be effectively used.

  Then, by operating the seedling planting rod 52 only for the first set time, it is possible to prevent seedlings from being planted multiple times in the same place even when the return operation of the auxiliary transmission operation member 16 is forgotten. Consumption can be reduced.

  Further, after the first set time has elapsed, when the detection state of the operation detection member 101 is maintained for the second set time, the seedling planting rod 52 is configured to operate again, so that the traveling vehicle body 2 can be used during maintenance or the like. Without moving the seedling, the seedling placing member 51 can be moved to the left and right stroke ends, and the operability is improved.

In FIG. 13, the operation | movement flowchart of the 2nd control of the seedling transplanter of this embodiment is shown.
As the second control, the following operation is performed by signals from the ground detection members 102 of the center float 55 and the side floats 56 and 56. That is, when the grounding detection member 102 detects the grounding of the floats 55, 56, 56, when the operation detection member 101 enters the detection state, the seedling implantation rod 52 is operated for the first set time, and the grounding detection member 102 When the ground contact of the floats 55, 56, 56 is not detected, the seedling planting rod 52 is continuously operated while the operation detection member 101 is in the detection state. The ground contact detection member 102 is a tilt angle sensor for the center float 55 and the side floats 56 and 56 and a pressure sensor for the hydraulic pressure of the lifting hydraulic cylinder 46.

  When the ground contact detection member 102 detects the ground contact of the floats 55, 56, 56, when the operation detection member 101 enters the detection state, the seedling planting rod 52 is operated for the first set time, and the ground contact detection member 102 is floated. When the ground contact of 55, 56, 56 is not detected, the seedling planting device 4 is configured to continuously operate while the operation detection member 101 is in the detection state. Necessary operations that differ depending on the position can be performed without causing an erroneous operation. This improves operability.

  That is, when the seedling planting device 4 is in the lower position, seedlings can be planted in a place where it is necessary to plant a single plant on the spot without moving. The left / right movement operation of the member 51 can be easily performed, and the work efficiency and operability are improved.

  Further, by using the ground contact detection member 102 of each of the floats 55, 56, 56 as a reference, the ground contact detection member 102 detects whether or not the seedling planting device 4 is not fully lifted regardless of the position of the seedling planting device 4. It can be positioned, and work efficiency is improved.

  In the second control, when the operation detection member 101 is not in the detection state while the seedling planting rod 52 is continuously operated, the trunnion shaft of the continuously variable transmission 23 is immediately returned to the neutral position, Thereafter, the planting clutches 112 and 115 are set to the “disengaged” state.

In FIG. 14, the operation | movement flowchart of the 3rd control of the seedling transplanter of this embodiment is shown.
As the third control, when the grounding detection member 102 does not detect the grounding of the floats 55, 56, 56 in the second control, the seedlings are not seeded for the first time after the operation detection member 101 continues the detection state for the third set time. The planting rod 52 is operated continuously.

  When the ground contact detection member 102 does not detect the ground contact of the floats 55, 56, 56, the seedling planting rod 52 is continuously operated after the detection state of the third detection time of the operation detection member 101 is continued. As a result, even if the operator moves the auxiliary speed change operation member 16 to a predetermined position by mistake, the seedling planting rod 52 does not operate immediately. It is possible to prevent consumption of excess seedlings and damage to the seedling planting device 4.

In FIG. 15, the operation | movement flowchart of the 4th control of the seedling transplanter of this embodiment is shown.
As the fourth control, unlike the second and third controls, the seedling planting rod 52 is switched to continuous operation, and the engine 20 and the like are stopped. That is, when the grounding detection member 102 detects the grounding of each of the floats 55, 56, 56, when the operation detection member 101 enters the detection state, the seedling planting rod 52 is operated for the first set time, and the grounding detection member When 102 does not detect the grounding of each of the floats 55, 56, 56, when the detection signal is output from the operation detection member 101, the engine 20 is stopped and the detection signal is output again in this stopped state. Then, the engine 20 is started. Here, the “stop state” of the engine 20 means both a state where the engine 20 is completely stopped and a case where there is almost no output of the engine 20 (for example, the rotation of the engine 20 is 800 to 1000 rpm per minute). Including.

  When the grounding detection member 102 detects the grounding of each float 55, 56, 56, when the operation detection member 101 enters the detection state, the seedling planting rod 52 is operated for the first set time, and the grounding detection member 102 When the ground contact of each float 55, 56, 56 is not detected, when the detection signal is output from the operation detection member 101, the engine 20 is stopped, so that it varies depending on the vertical position of the seedling planting device 4. Necessary operations can be performed without causing erroneous operations. This improves operability.

  That is, when the seedling planting device 4 is in the lower position, seedlings can be planted in a place where it is necessary to plant one stock on the spot without moving, while when it is in the upper position, the engine 20 Can be easily stopped and started, and operability is improved. Furthermore, the operation to stop the traveling becomes easier, so unnecessary operation of the engine 20 at the time of seedling replenishment work, etc. is suppressed, excess fuel consumption and exhaust gas emission are suppressed, and fuel efficiency and environmental adaptability are improved. To do.

  In addition, since the engine 20 is started when the detection signal is output again when the engine 20 is stopped, the traveling vehicle body 2 can be prevented from suddenly starting when the engine 20 is restarted. Improves seedling planting accuracy.

In FIG. 16, the operation | movement flowchart of the 5th control of the seedling transplanter of this embodiment is shown.
As the fifth control, in the fourth control, the engine 20 is stopped and the deceleration operation detection member 103 that detects the deceleration operation of the deceleration operation member that decelerates the traveling vehicle body 2 is in the detection state. When the detection signal is output from the operation detection member 101, the engine 20 is started.

  A configuration in which the engine 20 is started when a detection signal is output from the operation detection member 101 when the engine 20 is in a stopped state and the deceleration operation detection member 103 that detects the deceleration operation of the deceleration operation member is in the detection state. As a result, restart of the engine 20 due to an erroneous operation of the auxiliary transmission operation member 16 is prevented, and sudden start of the seedling transplanter and the like can be prevented, so that work safety is improved.

In FIG. 17, the operation | movement flowchart of the 6th control of the seedling transplanter of this embodiment is shown.
As the sixth control, in the second and third controls, when the ground contact detection member 102 detects the ground contact of each float 55, 56, 56 and the seedling planting rod 52 is operated for the first set time. When the planting clutch mechanism 112, 115 for switching on / off the planting clutch mechanism 112, 115 is turned on, the planting clutch mechanism 112, 115 is turned “off” and the output of the continuously variable transmission 23 is lowered. As shown in FIG. 4, the planting on / off member 105 is a button switch provided below the auxiliary transmission operation member 16 of the control panel 33. Usually, when the seedling planting rod 52 is rotated only for the first set time, the seedling planting rod 52 after being rotated waits for the tip of the seedling planting rod 52 not to contact the field when the seedling planting device 4 is lowered. The planting clutch mechanisms 112 and 115 are insulated so as to stop at the position. By this control, the seedling planting rod 52 can be stopped in places other than this standby position.

  With such a configuration, even when the operator operates the seedling planting rod 52 for the first set time due to an erroneous operation, the operation can be stopped immediately. This prevents seedlings from being planted in a place unintended by the operator, reduces seedling consumption, and improves seedling planting accuracy.

In FIG. 18, the operation | movement flowchart of the 7th control of the seedling transplanter of this embodiment is shown.
As the seventh control, in the second and third controls, the grounding detection member 102 does not detect the grounding of the floats 55, 56, 56, the operation detection member 101 is set in the detection state, and the seedling planting rod 52 is continuously operated. When the planting on / off member 105 is operated during operation, the on / off of the planting clutch mechanisms 112 and 115 is changed.

  When the operation detecting member 101 is in the detection state and the seedling planting rod 52 is continuously operated, when the planting on / off member 105 is operated, on / off of the planting clutch mechanisms 112 and 115 is changed. As a result, it becomes easy to rotate the seedling planting rod 52, which may stop at a position other than the standby position during continuous operation, to the standby position, thereby preventing the seedling from being planted in a place not intended by the operator. As seedling consumption decreases, seedling planting accuracy improves.

In FIG. 19, the operation | movement flowchart of the 8th control of the seedling transplanter of this embodiment is shown.
As an eighth control, after the engine 20 is started, the rise detection member 104 that detects that the seedling planting device 4 has moved to a predetermined height or higher detects the rise of the seedling planting device 4 beyond the predetermined height. When there is not, the planting clutch mechanisms 112 and 115 do not enter the “on” state even when the operation detection member 101 of the auxiliary transmission operation member 16 is in the detection state, and planting driving force is supplied to the seedling planting device 4. Not.

  With the above configuration, even if the auxiliary transmission operation member 16 is erroneously operated at the start of traveling, the seedling planting device 4 does not operate, and seedlings are prevented from being planted in a place not intended by the operator. Consumption is reduced.

  Moreover, since the driving | operation of the seedling planting apparatus 4 which an operator does not intend can be prevented, the seedling planting apparatus 4 can be prevented from being damaged.

  FIG. 20 shows a left side view of the seedling transplanter according to the second embodiment. In the seedling transplanter according to the present embodiment, the battery 120 is disposed below the preliminary seedling mount 38. A presser pin 122 for pressing the battery cover 121 of the battery 120 from above is provided at the bottom of the frame of the preliminary seedling table 38. The presser pin 122 is positioned at the front and rear center of the battery 120 so that the battery cover 121 cannot be removed. With this presser pin 122, a rubber band or the like for fixing the battery 120 can be omitted, and the cost can be reduced by reducing the number of parts.

  In FIG. 21, the top view of the floor step 35 periphery of the seedling transplanter concerning 3rd embodiment is shown. A step mat 123 is laid on the floor step 35 located on the center of the left and right sides of the aircraft. The step mat 123 is fixed to the floor step 35 by fixing clips 124... Positioned on the rear side of the machine body and fixing pieces 125. The fixing clip 124 fixes the step mat 123 to the floor step 35 with screws. The fixing piece 125 is a convex body provided on the back surface of the floor step 35, and the fixing piece 125 is inserted into the floor step 35. Fix it. The fixed piece 125 can be easily removed by the operator pulling the portion of the step mat 123 upward, and after lifting the step mat 123, the worker can move the stock lever 126 below the floor step 35.
