FIG. 3 is a vertical cross-sectional view of the fertilizing device 26 seen from the arrow α shown in FIG.

4(a) is a schematic plan view of the fertilizing device 26 without the fertilizing hopper, and FIG. 4(b) is a schematic front view of the discharge duct and eight delivery devices of the fertilizing device 26. FIG.

On the other hand, FIG. 5 is a schematic front view of the vicinity of the fertilizing transmission mechanism of the fertilizing device 26. As shown in FIG.

As shown in FIG. 4( a ), the fertilizing device 26 is composed of a blower 41 provided at the left end, a three-pronged duct, and an air switching pipe 14 whose left opening is connected to the blower 41 , an air An air chamber 42 connected to the right front opening of the switching pipe 14, a discharge duct 16 connected to the right rear opening of the air switching pipe 14 and arranged behind the air chamber 42, and fertilizer to be supplied to the field. A fertilizing hopper 27 (see FIGS. 3 and 5) for storage, eight delivery devices 34 (see FIGS. 4A and 5, only one is shown in FIG. 3) provided below the fertilizing hopper 27, and , eight connection pipes 38 (see FIG. 3, only one is shown) provided below each delivery device 34 and connected to the air chamber 42, and the front end is connected to the rear end of each connection pipe 38. A total of eight fertilizing hoses 62 (see FIGS. 3 and 5) connected and extending to the bottom of the seedling planting section 63 (see FIG. 1), and a fertilizing transmission mechanism 100 (see FIG. 5) for driving the delivery device 34. ) and a fertilization amount adjustment mechanism 200 (see FIG. 4A) for adjusting the amount of fertilization applied to the field.

As shown in FIG. 4A, the blower 41 includes a blower motor 43 and an intake duct 13. When the blower motor 43 is driven, air sucked through the intake duct 13 is supplied into the air switching pipe 14. be done.

The three-pronged air switching pipe 14 is provided with a switching valve 15 therein. The switching valve 15 is positioned in the air switching pipe 14 so as to close the air flow path to the air chamber 42 and to allow the air flow to the discharge duct 16. It is configured to be switchable between the attitude of closing the path and the attitude of closing the path.

When the switching valve 15 takes a position to close the air flow path to the air chamber 42 , the air supplied from the blower 41 passes through the discharge duct 16 to the right, and the switching valve 15 moves to the discharge duct 16 . air supplied from the blower 41 is supplied into the air chamber 42 . The air supplied into the air chamber 42 is supplied into the fertilizing hose 62 via the connecting pipe 38 shown in FIG.

On the other hand, the eight feed-out devices 34 provided below the fertilizer application hopper 27 each include a discharge shutter 17 (see FIG. 3) for opening and closing a discharge passage (not shown) connecting the lower part of the fertilizer application hopper 27 and the discharge duct 16. , a feed roll 35 (see FIG. 3) having a feed groove 37 on its outer peripheral surface, and the fertilizer stored in the lower part of the fertilizer application hopper 27 is fed into the feed groove 37 by gravity.

When the delivery device 34 is driven via the fertilizing transmission mechanism 100 (see FIG. 5), the delivery shaft 36 (see FIG. 3) is inserted through a hole (not shown) penetrating the delivery roll 35 in the lateral direction. ) is rotated, and the delivery roll 35 is rotated at this time, so that the fertilizer supplied into the delivery groove 37 is delivered downward from the delivery device 34 .

Fertilizer delivered by the delivery roll 35 is fed into the connecting pipe 38 shown in FIG. At this time, since air is supplied from the front air chamber 42 into the connecting pipe 38 , the fertilizer supplied into the connecting pipe 38 is supplied to the field through the fertilizing hose 62 .

On the other hand, when the switching valve 15 is switched to the attitude of closing the air flow path to the air chamber 42 , the discharge shutter 17 of each delivery device 34 opens in conjunction with this, and the fertilizing hopper 27 stores the fertilizer. The applied fertilizer falls into the discharge duct 16.

At this time, since air is supplied into the discharge duct 16, the fertilizer that has fallen from the fertilizing hopper 27 is discharged from the discharge port 20 (FIGS. 4 and 5) that opens downward at the right end of the discharge duct 16. see). Therefore, if a bag is prepared in advance under the discharge port 20, the fertilizer stored in the fertilizer application hopper 27 can be collected.

Here, the discharge duct provided in the fertilizing device of the conventional seedling transplanter has substantially the same inner diameter from the left end connected to the three-pronged air switching pipe to the discharge port. To the right side, that is, toward the downstream side, the amount of fertilizer passing through the inside of the discharge duct increases, and the discharge duct curves downward on the downstream side. Fertilizer sometimes clogged in the portion downstream from the point close to the device.

On the other hand, in this embodiment, as shown in FIG. 4B, the discharge duct 16 is located on the rightmost side of the eight feeding devices 34 (first feeding device). It has a shape that widens downward from a portion close to the . In other words, as shown in FIG. 4(b), the lower end of the discharge duct 16, which is constructed at a substantially constant height from the upstream side (left side, right side in the drawing), is located on the rightmost side of the feeding device. The discharge duct 16 has a shape that descends downward toward the discharge port 20 from the portion close to the discharge port 34, and the inner diameter of the discharge duct 16 in the vertical direction extends from the portion close to the delivery device 34 located on the rightmost side to the discharge port 20. is configured to increase toward

That is, on the left side, which is the upstream side of the feeding device 34 located on the rightmost side, the vertical cross section of the discharge duct 16 has a substantially circular shape, and on the downstream side from the portion close to the feeding device 34 located on the rightmost side, the discharge The longitudinal section of the duct 16 has an elliptical shape extending in the vertical direction.

Therefore, in the discharge duct 16, it is possible to prevent the fertilizer from being clogged in the portion downstream from the portion close to the delivery device 34 located on the most downstream side.

The operator operates the discharge lever 21 shown in FIG. 5 to switch the switching valve 15 shown in FIG. It is possible to switch to a posture in which the air flow path is closed. Therefore, when fertilizer is to be supplied to a field, the discharge lever 21 is operated to switch the switching valve 15 to a posture that closes the air flow path to the discharge duct 16, and the fertilizer stored in the fertilizer application hopper 27 is discharged. In the case of discharging, the posture may be switched to block the flow path of the air to the air chamber 42 .

On the other hand, part of the driving force for running transmitted from the transmission case 30 shown in FIG. It is transmitted to a delivery shaft 36 (see FIG. 3) that is rotationally driven.

As shown in FIG. 5, the right rear wheel gear case 51 has a fertilizing clutch device 155 on its upper portion for switching whether or not to transmit the driving force to the fertilizing device 26. The left end of the fertilizing clutch device 155 is provided with a fertilizing transmission output shaft 105 .

A fertilization transmission drive rod 96 is attached to the fertilization transmission output shaft 105 so as to be able to reciprocate up and down.

Between the relay rod 104 and the fertilizing transmission drive rod 96 is arranged a connecting plate 95 (see FIGS. 3 and 5) which swings vertically with a swing connecting fulcrum pin 94 as a fulcrum. A sub-drive rod 98 (see FIGS. 3 and 5) is connected to the end.

The upper end of the sub-driving rod 98 is connected to the rear end of a delivery rotary arm 99 (see FIG. 3) whose front and rear parts swing vertically around a delivery rotary pin 101 (see FIG. 3). Further, the front end of the delivery rotating arm 99 and the delivery shaft 36 for rotating the delivery roll 35 are connected by a fertilizing drive arm 97 .

By configuring the fertilizing transmission mechanism 100 as described above, part of the driving force for running transmitted to the rear wheel gear case 51 is transferred to the fertilizing clutch device 155 (see FIG. 5) when the fertilizing clutch device 155 (see FIG. 5) is engaged. It can be transmitted to the delivery shaft 36 .

On the other hand, the amount of fertilizer delivered by each of the eight delivery devices 34 of the fertilizer applicator 26 and supplied to the field is increased or decreased by the fertilizer application amount control mechanism 200 as follows.

6A and 6B are explanatory diagrams showing the relationship between the position of the feeding rotation pin 101 and the swing amount of the front portion of the feeding rotation arm 99. FIG. FIG. 6B is an explanatory diagram showing the amount of swinging of the front portion of the feeding rotation arm 99 in the case where the feeding rotation pin 101 is positioned relatively forward. It is explanatory drawing which shows the amount of movement.

As shown in FIG. 4, the fertilizer application amount adjustment mechanism 200 includes a ball screw 18, a fertilizer application amount adjustment motor 103 that rotates the ball screw 18, and a ball nut 19 that is screwed into a spiral groove formed on the surface of the ball screw 18. It has

As shown in FIG. 3, the ball nut 19 is attached with a feed-out rotating pin 101, and the ball nut 19 is moved back and forth on the ball screw 18 by driving the fertilizer amount adjusting motor 103. 3 and 6 is moved back and forth together with the ball nut 19. As shown in FIG.

As shown in FIGS. 6(a) and 6(b), the feeding rotation arm 99 is provided with an elongated hole 102 penetrating in the left-right direction. , the feeding rotation pin 101 is arranged. Therefore, the delivery rotation arm 99 is configured such that the front portion thereof can swing vertically around the delivery rotation pin 101 . It should be noted that the diameter of the feeding rotation pin 101 is configured to have a size that abuts on the upper end portion and the lower end portion of the elongated hole 102 .

As shown in FIG. 6(a), when the feeding rotation pin 101 is moved rearward by the drive of the fertilizer application amount adjusting motor 103, the feeding rotation pin 101 is positioned further forward (see FIG. 6). (b)), the amount of vertical swing of the front portion of the delivery rotation arm 99 is increased.

When the amount of vertical swing of the front portion of the delivery rotary arm 99 increases, the amount of rotation of the fertilizing drive arm 97 (see FIG. 3) attached to the front end of the delivery rotary arm 99 increases, and the time required for the rotation increases. becomes longer.

As a result, the frequency at which the feeding shaft 36 and the feeding roll 35 shown in FIG. 3 makes one rotation becomes less than the frequency at which the fertilizing transmission drive rod 96 shown in FIG. 5 reciprocates in the vertical direction. Therefore, the amount of fertilizer delivered in a given period of time from each delivery device 34 is reduced.

On the other hand, as shown in FIG. 6(b), when the feed rotation pin 101 is moved forward by the driving of the fertilizer application amount adjusting motor 103, the feed rotation pin 101 is positioned further rearward. As compared with the case (see FIG. 6(a)), the amount of vertical swing of the front portion of the feed-out rotating arm 99 is reduced.

When the vertical swing amount of the front portion of the delivery rotary arm 99 decreases, the amount of rotation of the fertilizing drive arm 97 (see FIG. 3) attached to the front end portion of the delivery rotary arm 99 is reduced, and the time required for rotation is reduced. becomes shorter.

As a result, the frequency at which the feeding shaft 36 and the feeding roll 35 shown in FIG. 3 make one rotation increases with respect to the frequency at which the fertilizing transmission drive rod 96 shown in FIG. 5 reciprocates in the vertical direction. Therefore, the amount of fertilizer delivered in a given period of time from each delivery device 34 increases.

In this way, by moving the delivery rotation pin 101 in the front-rear direction by the fertilizer application amount adjusting motor 103, the delivery amount of the fertilizer in each of the eight delivery devices 34 (see FIG. 4) of the fertilizer applicator 26 is increased, Alternatively, it can be decreased.

FIG. 7 is a block diagram of the control system, detection system, input system, display system and drive system of the seedling transplanter 1 shown in FIG.

As shown in FIG. 7, the control system of the seedling transplanter 1 includes a controller 87 that controls the overall operation of the seedling transplanter 1, a ROM 92 that stores control programs and the like, and a RAM 91 that stores various data. ing.

As shown in FIG. 7, the detection system of the seedling transplanter 1 includes a steering sensor 58 that detects the angle at which the steering handle 56 is steered, and a rear wheel gear case 51 that counts the number of revolutions of the rear wheel 6. and a feed detection sensor 107 for detecting the amount by which the feed roll 35 is rotated.

As shown in FIG. 7, the seedling transplanter 1 includes an operation unit 54 functioning as an input system. The operation unit 54 includes a monitor 22 functioning as a setting unit, a first operation unit and a second operation unit. It has a fertilization adjustment switch 31 that functions as a The monitor 22 also has a display (not shown in FIGS. 1 to 7) that functions as a display system for the seedling transplanter 1. As shown in FIG.

As shown in FIG. 7, the drive system of the seedling transplanter 1 consists of an engine 7 provided below the operator's seat 48 and an electronic engine 7 that expands and contracts the elevating hydraulic cylinder 12 when the seedling planting section 35 is raised and lowered. A hydraulic valve 88, an HST servomotor 150 that adjusts the opening of a trunnion shaft (not shown) in the hydraulic continuously variable transmission 25, and a subtransmission that switches the state of the subtransmission mechanism provided in the transmission case 30. A motor 152, a fertilizer application amount adjustment motor 103 that rotates the ball screw 18 of the fertilizer application amount adjustment mechanism 200 and adjusts the amount of fertilizer applied to the field by the fertilizer application device 26, and a fertilizer application clutch motor 123 that operates the fertilizer application clutch device 155. .

FIG. 8 is a drawing showing the monitor 22 of the operation unit 54 shown in FIG.

The monitor 22 is provided below the steering handle 56 and, as shown in FIG. 8, includes a display 44, a jog dial 45, a push switch 50 provided above the jog dial 45, and a speaker (not shown). ing.

FIG. 8 shows a state in which a screen for adjusting the amount of fertilizer applied to the field by the fertilizing device 26 is displayed on the display 44. In this embodiment, the screen displayed on the display 44 is: It is configured so that the amount of fertilizer applied can be set.

Specifically, when the operator rotates the jog dial 45 clockwise or counterclockwise, the fertilization amount numerical value ( When the unit: kg/10a) is increased or decreased and the push switch 50 is pressed, the amount of fertilizer applied to the field is set.

When the numerical value of the fertilization amount setting unit 46 is changed as described above and the amount of fertilization applied to the field is set, the controller 87 controls the fertilization amount adjustment motor 103 functioning as a fertilization amount adjustment means. is configured to be moved to a front-rear position corresponding to the set amount of fertilization applied.

Therefore, the operator can operate the jog dial 45 and the push switch 50 of the monitor 22 in advance to set an arbitrary fertilizer application amount before planting seedlings while supplying fertilizer to the field. .

In the actual field, there has been, in part, a demand to reduce the amount of fertilizer supplied by the fertilizer applicator 26, but heretofore it has been difficult to meet this demand.

In other words, when seedlings are planted near the entrance of a field and fertilizer is supplied, even if fertilizer is supplied at the same level as other places, the fertilizer will wash away with water and the fertilizer will be wasted. , it is desirable to temporarily (partially) reduce the amount of fertilizer applied by the fertilizing device 26 during travel, and also to reduce the amount of fertilizer applied by the fertilizing device 26 every year at the same place in the field, that is, a place with high soil fertility In places where the soil is deep, the rice plants may overgrow and fall over.

However, if the jog dial 45 and the push switch 50 of the monitor 22 are operated to reduce the fertilizer application amount at a place where the fertilizer application amount is desired to be reduced, and the fertilizer application amount is not returned before the fertilizer is supplied to the subsequent planting portion, The amount of fertilizer supplied will decrease overall, so if you do not return to the amount of fertilizer applied before the change when you pass the place where you want to reduce the amount of fertilizer applied, fertilizer will be added again after finishing the work. It was very troublesome.

In light of this situation, in the seedling transplanter 1 according to this embodiment, the operation unit 54 shown in FIGS. Thus, by operating the fertilization adjustment switch 31, the amount of fertilization can be easily (partially) reduced (reduced fertilization) even while the traveling vehicle 2 is running. ing.

FIG. 9(a) is a schematic plan view of the vicinity of the fertilization adjustment switch 31 provided in the operation unit 54 of the seedling transplanter 1, and FIG. 9(b) shows that the fertilization adjustment switch 31 is operated, FIG. 10 is a drawing showing a screen displayed on display 44 when reduced. FIG.

The fertilization adjustment switch 31 is located on the right side of the central portion in the horizontal direction of the monitor 22 shown in FIG. 8, and as shown in FIG. is located to the left of the

As shown in FIG. 9(a), the fertilization adjustment switch 31 is configured such that its front portion 32 and rear portion 33 can be pressed, respectively, and is configured to allow two-way input as follows. .

In this embodiment, every time the rear portion 33 of the fertilization adjustment switch 31 is pressed, the fertilization amount set by operating the jog dial 45 and the push switch 50 of the monitor 22 is decreased by 5%. It is

On the other hand, when the front portion 32 of the fertilization adjustment switch 31 is pressed, the amount of fertilization reduced by the push operation of the rear portion 33 of the fertilization adjustment switch 31 is displayed as It is configured to return to the set fertilization amount.

For example, when the monitor 22 is set to 50 kg/10 a, when the operator presses the rear portion 33 of the fertilization adjustment switch 31 once, the fertilization amount adjustment motor 103 operates the feed shown in FIG. The rotating pin 101 is moved to change the state to supply fertilizer in an amount of 47.5 kg/10a to the field. Thereafter, every time the rear portion 33 of the fertilizer application adjustment switch 31 is pressed, the fertilizer application amount is increased by 5 from the fertilizer application amount set on the monitor 22, such as 45 kg/10a, 42.5 kg/10a, and 40 kg/10a. It is configured to be decreased by %.

In this embodiment, by pressing the rear part 33 of the fertilization adjustment switch 31 in this manner, the fertilization amount set on the monitor 22 can be reduced by up to 50%. there is Therefore, in the above example, when the rear portion 33 of the fertilization adjustment switch 31 is pressed 10 times and the amount of fertilizer applied is reduced to 25 kg/10a, which is a state of 50% reduction, the rear portion 33 of the fertilization adjustment switch 31 is pressed, the controller 87 is configured to invalidate the fertilizer application amount reduction operation.

In addition, at this time, the seedling transplanter 1 is configured to sound a short "beep-beep" buzzer from the speaker of the monitor 22 to warn the operator that the fertilizer application amount cannot be reduced any further. It is

Furthermore, in the present embodiment, while the rear portion 33 of the fertilization adjustment switch 31 is pressed and the fertilization amount is being decreased, the display 44 of the monitor 22 shows the fertilization amount as shown in FIG. 9(b). is being reduced, and the rate of decrease in fertilizer application amount at that time is always displayed.

FIG. 9(b) shows the screen when the rear portion 33 of the fertilization adjustment switch 31 is pressed twice and, as a result, the amount of fertilizer applied is reduced by 10% from the amount set on the monitor 22. state is indicated.

Further, in this embodiment, the rear portion 33 of the fertilization adjustment switch 31 is pressed, and the fertilization adjustment switch 31 is turned on in a state where the amount of fertilizer application is reduced by 5% to 50% from the amount of fertilizer application set on the monitor 22. When the front portion 32 is pressed, the fertilizer application amount is returned to the fertilizer application amount set on the monitor 22 as described above.

Therefore, the operator can press the front portion 32 of the fertilization adjustment switch 31 after passing the place where the amount of fertilizer application is desired to be reduced in the field, thereby returning the amount of fertilizer application to the amount before the reduction. .

1 and 2, the rear part 33 of the fertilization adjustment switch 31 is similarly pressed, and the fertilization amount is reduced by 5% to 50% from the fertilization amount set on the monitor 22. The fertilization amount is returned to the fertilization amount set on the monitor 22 even when the seedling planting unit 63 is raised to the non-working position.

Here, when the seedling transplanter 1 is turned around in the headland of a field, the seedling planting section 63 is normally raised to the non-working position automatically or by an operator.

Therefore, when the seedling planting section 63 is raised to the non-working position, the state before the fertilizer application amount is reduced is restored. It is possible to effectively prevent a situation in which the remaining field is traveled to the end.

Furthermore, in this embodiment, even when the key cylinder 24 shown in FIG. configured to be

According to this embodiment, every time the rear portion 33 of the fertilization adjustment switch 31 is pressed, the amount of fertilization set on the monitor 22 is reduced by 5%. During the seedling planting operation, the operator presses the rear part 33 of the fertilizer application adjustment switch 31 once or multiple times according to the desired reduction ratio of the fertilizer application amount at the location where the fertilizer application amount is desired to be reduced, thereby supplying the seedlings. Rice lodging can be prevented by reducing the amount of fertilizer applied.

Furthermore, according to this embodiment, regardless of the display state of the display 44 of the monitor 22, simply pressing the rear portion 33 of the fertilization adjustment switch 31 allows the amount of fertilization to be reduced, even during operation. , the operation of reducing the amount of fertilizer application can be easily performed in a short time at any place in the field.

Further, according to this embodiment, simply by pressing the rear portion 33 of the fertilization adjustment switch 31, the amount of fertilizer applied to the field by the fertilization device 26 can be easily reduced. Also, there is no need to provide the traveling vehicle 2 with an ultrasonic sensor, so the seedling transplanter 1 can be manufactured at low cost.

Further, in this embodiment, when the front portion 32 of the fertilization adjustment switch 31 is pressed in a state where the rear portion 33 of the fertilization adjustment switch 31 is operated to reduce the amount of fertilizer applied, the amount of fertilizer applied by the fertilization device 26 is reduced. , the fertilization amount set on the monitor 22 is restored, so that the operator presses the front portion 32 of the fertilization adjustment switch 31 after passing through the place where the fertilization amount is desired to be reduced. It is possible to return to the original fertilizer application amount easily and in a short time.

Further, according to this embodiment, when the seedling planting unit 63 is raised to the non-working position, the amount of fertilizer applied by the fertilizer applicator 26 is returned to the amount of fertilizer applied set on the monitor 22. Therefore, when the seedling transplanter 1 is rotated and the seedling planting unit 63 is raised to the non-working position in the headland of the field, the amount of fertilizer applied by the fertilizer applicator 26 is set on the monitor 22. It is possible to effectively prevent a situation in which the vehicle is returned to the applied amount of fertilizer and, therefore, travels to the end of the remaining field with the applied amount of fertilizer reduced.

Furthermore, according to this embodiment, the operation member used when decreasing the amount of fertilizer applied and the operation member used when wanting to restore the decreased amount of fertilizer applied are the single operation member, the fertilizer application adjustment switch 31. Because it is structured, it is easy to operate.

In this embodiment, the lower end of the discharge duct 16 of the fertilizing device 26 slopes downward toward the discharge port 20 from the portion adjacent to the delivery device 34 closest to the discharge port 20 . As a result, since the inner diameter of the discharge duct 16 in the vertical direction increases toward the discharge port 20, from the portion of the discharge duct 16 that is closest to the delivery device 34 closest to the discharge port 20, It is possible to prevent clogging of the fertilizer on the downstream side of the discharge port 20 .

Further, as described above, the lower end portion of the discharge duct 16 is inclined downward from the portion adjacent to the delivery device 34 closest to the discharge port 20 toward the downstream side, thereby increasing the vertical inner diameter. However, normally, the discharge port 20 of the discharge duct 16 of the fertilizing device 26 is configured to be positioned below the upstream portion of the discharge duct 16 to prevent clogging of the fertilizer. In order to prevent interference with other members, such as when the inner diameter of the exhaust duct 16 is increased in the longitudinal direction or the lateral direction of the fuselage, or when the upper end of the exhaust duct 16 has a shape that expands upwards. There is no

In the "screen for setting the specific gravity" and the "screen for setting the trial feeding amount" displayed as a result of pressing the portion labeled "Delivery amount", the operator similarly increases the slider 121. By operating the switch 118, the decrease switch 119, the change amount switch 124, the decision switch 124 and the close switch 27, the setting can be made or the setting screen can be closed.

On the other hand, FIG. 14(b) is a drawing showing a "screen for setting the reduction rate" displayed on the display of the terminal 112. As shown in FIG.

In this embodiment, when the terminal 112 is operated to press a portion labeled "fertilization reduction rate" in the fertilizer information display section 136 on the "variable fertilization setting screen", the screen shown in FIG. 14(a) is displayed. It is configured to display the "screen for setting the reduction rate" on the display.

As shown in FIG. 14(b), in the "screen for setting the fertilizer reduction rate", a fertilizer reduction rate display section 132 representing the set fertilizer reduction rate, an increase switch 118 and a decrease switch 119 are displayed.

By pressing the increase switch 118 or the decrease switch 119, the operator can increase or decrease the manure reduction rate.

As shown in FIG. 14(b), a no-reduction switch 129, a standard switch 128, and a determination switch 124 are provided from the left at the bottom of the "screen for setting the reduction rate".

When the no-reduction switch 129 is pressed, all of the reduction rates 1 to 3 are set to 0%. Therefore, the operator can easily and quickly reduce the manure reduction rate 1 to 3 items by pressing the no manure reduction switch 129 once without pressing the manure reduction switch 119 repeatedly to reduce the items to 0%. At time, the reduction rate 1-3 can be set to 0%.

On the other hand, when the standard switch 129 is pressed, as shown in FIG. %. Therefore, the operator can easily and in a short time select the items of the fertilizer reduction rates 1 to 3 by pressing the no-fertility-reduction switch 129 once without pressing the increase switch 118 or the decrease switch 119. rate can be set.

After setting the desired fat reduction rate by using the increase switch 118, the decrease switch 119, the no fat reduction switch 129, or the standard switch 129 as described above, the decision switch 124 shown in FIG. 14(a) is pressed. By being operated, the set fertilizer reduction rate data is first written in the storage unit of the terminal 112, and then the set fertilizer reduction rate data is transmitted to the seedling transplanter communication unit 131. It is That is, until the determination switch 124 is pressed, the data regarding the set value of the fertilizer reduction rate is not written in the storage section of the terminal 112 , and the data of the set fertilizer reduction rate is not transmitted to the seedling transplanter communication section 131 . By configuring in this way, the actual situation in which the fertilizer reduction rate is erroneously set is prevented.

As shown in FIG. 14(b), in the "screen for setting the fertilizer reduction rate" as well as in the "screen for setting the basic fertilizer application amount", a "close switch" represented by an "x" is displayed in the upper right part of the screen. 127" is provided, and when the close switch 127 is pressed, the screen for setting the fertilizer reduction rate is closed.

Here, when the fertilizer reduction rate is set using the increase switch 118, the decrease switch 119, the no-fertilization switch 129, or the standard switch 129, the close switch 127 is operated without the determination switch 124 being operated. , the terminal 112 displays on the display that the fertilizer reduction rate has not been changed and asks whether or not to close the "screen for setting the fertilizer reduction rate", as in the case of the "screen for setting the basic fertilizer application amount". , a "yes" switch and a "no" switch, respectively, are displayed in the dialog box.

At this time, if the "yes" switch is pressed, the terminal 112 displays the "variable fertilization setting screen" on the display without writing the data of the set fertilizer reduction rate to the storage unit, and displays " If the "No" switch is pressed, the dialog box disappears and the screen for setting the fertility reduction rate is displayed again on the display. By configuring in this way, the operator can be prompted to operate the determination switch 124 .

On the other hand, FIG. 14(c) is a drawing showing a dialog box displayed on the "variable fertilization setting screen".

In general, the amount of fertilizer applied to a field by a fertilizing device slightly fluctuates depending on the humidity and the state of the fertilizing device. Also, in variable fertilization, it is very important to input a highly accurate specific gravity value of the fertilizer in order to supply an appropriate amount of fertilizer to each position of the field.

Therefore, in this embodiment, the terminal 112 displays the "variable fertilization setting screen" (information required for variable fertilization, namely, field, basic fertilization amount, specific gravity, trial feeding) shown in Fig. 13(a) on the display. screen for setting the amount and fertilizer reduction rate, etc.), the dialog box shown in FIG. is designed to encourage

As shown in FIG. 14(c), a confirmation switch 133 is provided at the bottom of the dialog box. When the confirmation switch 133 is pressed, the dialog box is hidden for the first time, and the "variable fertilization setting" is displayed. screen", it is configured so that information necessary for variable fertilization can be set.

A check box 134 is provided above the confirmation switch 133. When the check box 134 is pressed, a check mark is displayed in the check box 134 as shown in FIG. 14(c). When the confirmation switch 133 is pressed in this state, the dialog box shown in FIG. 14(c) is not displayed on the "variable fertilization setting screen" thereafter. By configuring in this way, it is possible to prevent a situation in which a worker who correctly understands how to use the fertilizing device 26 feels annoyed by the dialog box when variable fertilization is performed.

Here, there is a service called "Agri Note" that allows workers to input information about their own farm work into a server connected to the Internet and check the information when necessary. In the machine, when linked with "Agrinaut", the value of specific gravity planned in advance in "Agrinaut" was set in the terminal, and the operator could not change the specific gravity on the terminal.

On the other hand, in this embodiment, when linked with "Agrinaut", the dialog box shown in FIG. is separately displayed, and when "prioritize specific gravity (trial feeding)" is selected, the value of the trial feeding amount can be set (changed) on the terminal 112. FIG. Therefore, it becomes possible to perform variable fertilization with higher precision.

Furthermore, when the operator normally sets the specific gravity value of the fertilizer on the terminal, the specific gravity of the fertilizer is calculated by setting the specific gravity value described in the fertilizer bag and by trial feed of the fertilizer applicator. However, in this embodiment, when a numerical value is set for the item "Specific gravity", "Specific gravity (set value)" is displayed and "Trial feeding amount" is displayed. When a numerical value is set for the item, "specific gravity (trial feeding)" is displayed. By configuring in this way, it is possible to confirm by which method the set specific gravity value was set. In FIG. 13(a), "trial feeding amount" is pressed, a numerical value is set on the "screen for setting the trial feeding amount", and as a result, the "specific gravity (set value )” is displayed, but if a numerical value is set on the “screen for setting specific gravity”, “specific gravity (setting value)” is displayed.

As described above, before the variable fertilization is performed, after the necessary information is set on the terminal 112 by the operator, when the rice planting start switch 141 shown in FIG. , the terminal 112 is configured to display on the display a "variable fertilization work screen" in which the state of the variable fertilization work of the seedling transplanter 1 is summarized.

FIG. 15(a) is a drawing showing the "variable fertilization work screen" displayed on the display of the terminal 112 of the seedling transplanter 1 shown in FIG. 12, and FIG. It is a drawing showing ".

As shown in FIG. 15A, the "variable fertilization work screen" includes a connection state display section 142, an operation setting state display section 143, a radio wave intensity display section 144, and a fertilizer information display section. 136, a reference value measurement state display section 146 that indicates the measurement state of the reference value, a fertilizer application amount graph display section 147, a soil depth graph display section 148, and a fertility graph display section 149 arranged at the bottom of the screen, and the right side of the screen. A rice-transplanting interruption switch 153, which is pressed when rice-transplanting is interrupted, a rice-transplanting end switch 154, which is pressed when rice-transplanting ends, and a manual switch 154, which is pressed when the reference value is manually measured. A measurement start switch 167 and a screen transition switch group 145 are provided.

Similar to the "variable fertilization setting screen" shown in FIG. 13(a), a connection state display section 142, an operation setting state display section 143, and a radio wave intensity display section 144 are displayed at the top of the "variable fertilization work screen." Since the necessary information is always displayed at substantially the same position even when the screen is changed, even a new operator can easily grasp the necessary information.

As in the case of the "variable fertilization setting screen", the operation setting state display section 143 displays which of the "main machine mode" and the "tablet mode" is set. , the terminal 112 does not accept pressing operations of the fertilizer information display section 136 , the rice planting end switch 154 , the manual measurement start switch 167 and the rice planting start switch 141 .

In this embodiment, when the variable fertilization is performed, after the rice planting start switch 141 is pressed, while the reference value is not acquired (condition 1), the reference value measurement state display unit 146 displays "reference value not yet While the reference value is being measured manually (Condition 2), the character string "Measurement" is displayed and the reference value is being measured manually (Condition 2). While the measurement is being performed automatically (Condition 3), the character string "Automatic reference value measurement in progress" is displayed, and after the reference value has already been measured (Condition 4), the character string "Reference value has been measured" is displayed. A column is displayed, and by configuring in this manner, the current measurement state of the reference value can be easily grasped.

On the other hand, when the rice planting interruption switch 153 is pressed (condition 5), the reference value measurement state display section 146 displays the character string "work interruption". Therefore, the worker can recognize that the data of the rice planting work is not recorded at this time.

If a plurality of these conditions 1 to 5 are satisfied at the same time, the terminal 112 selects any one of condition 5, condition 4, condition 3, condition 2, and condition 1 in descending order of priority. The character string is configured to be displayed on the reference value measurement state display section 146 . Further, when none of the conditions 1 to 5 are satisfied, nothing is displayed on the reference value measurement state display section 146 .

Note that the reference value measurement (teaching) refers to the work of measuring the electrical conductivity, water temperature, and depth of a predetermined section of a field using the soil sensor 114. It is necessary to conduct teaching in order to set the appropriate amount of fertilizer application in advance.

As shown in FIG. 15(a), in this embodiment, the fertilizer application amount graph display portion 147, the soil depth graph display portion 148 and the fertility graph display portion 149 are all displayed on the "variable fertilization work screen". is configured as Therefore, there is no need to switch the display of the amount of fertilizer applied, soil depth and fertility, and visibility and operability are improved.

Furthermore, in this embodiment, when each of the fertilizer applied amount graph display portion 147, the soil depth graph display portion 148 and the fertility graph display portion 149 is pressed, the pressed display portion 147, 148 or 149 is displayed. , a line graph showing the measured values of fertilizer application amount, soil depth or fertility over the past three minutes from the present is displayed, and the other two display portions display the current measured values as bar graphs. In other words, the operator can confirm only the item pressed as necessary among the items of fertilizer application amount, soil depth and fertility on the line graph. FIG. 15(a) shows a state in which the fertilizer application amount graph display unit 147 is pressed and the fertilizer application amount over the past three minutes is displayed in a line graph.

On the other hand, when each item of "basic fertilizer application amount", "specific gravity" or "trial delivery amount" displayed in the fertilizer information display section 136 is pressed, the "screen for setting basic fertilizer application amount" and "setting specific gravity" are displayed. screen" or "screen for setting trial feeding amount" is displayed. That is, even after the rice-transplanting start switch 141 is pressed, each value of the basic fertilizer application amount, the specific gravity, or the trial feed amount can be changed.

When the variable fertilization work by the fertilization device 26 is finished, the operator operates the rice planting end switch 154 shown in FIG. It is possible to make a transition to a "work record creation screen" (see FIG. 15(b)) for inputting information.

As shown in FIG. 15(b), the "work record creation screen" includes a connection status display section 142, an operation setting status display section 143, a radio wave intensity display section 144, and a A planting area display section 177 that displays the planting area of the planting area, a field name setting section 135 arranged below the planting area display section 177, a chemical input section 178, and a seedling input section 178, which is used during the seedling planting work. A seedling box number input 177 for displaying the number of seedling boxes used and inputting various information necessary to automatically calculate the number of seedling boxes used during seedling planting operations. A calculator 179 is provided.

In this embodiment, the seedling transplanter 1 calculates the shape and area of the field in which the seedlings are planted by the seedling planting unit 63 based on the output signal from the GNSS receiver 130, and the calculated area is , is configured to be displayed in the planted area display section 177 of the "work record creation screen". When the area where the seedlings are planted (planted area) is calculated, the number of planted rows is determined based on the data on the model of the seedling transplanter 1, and further, at the place where the hem clutch is cut , the planted area is calculated by summing up only the planted areas of the number of effective rows. The planting area displayed on the planting area display section 177 can also be calculated from the output signal from the rear wheel rotation sensor 29 of the seedling transplanter 1 .

In addition, in this embodiment, the number of seedling boxes used, the names of the herbicides and application agents used, the basic usage amount, the unit of the basic usage amount, and the total usage amount are automatically or by an operator. , are input, and these information can be saved as work results.

First, a method for inputting the number of seedling boxes used when the seedlings were planted by the seedling planting section 63 (total number of seedling boxes used in the entire field) into the seedling box number input section 176 will be described below. , add a detailed explanation.

As a method of inputting the number of seedling boxes into the seedling box number input section 176, there is a method in which the operator manually inputs the numbers directly into the seedling box number input section 176, and a method in which the operator directly inputs the number of seedling boxes counted by himself/herself. The number of plants to be planted, the amount of seedlings taken, or the number of times of lateral feeding is input by the operator to the number of plants to be planted input portion 183, the amount of seedlings taken input portion 184, and the number of times of lateral feeding input portion 185 displayed in the calculation portion 179. Based on the number of plants to be planted, the amount of seedlings taken, and the number of lateral feeding times, the number of used seedling boxes is automatically calculated by the terminal 112, and a method of automatically inputting it to the number of seedling boxes input section 176 is prepared. .

In order to automatically input the number of seedling boxes into the seedling box number input section 176 using the terminal 112, first, the number of plants to be planted per tsubo is input to the planted stock number input section 183, and the seedling collection amount input section 184. , and the number of lateral feeds (the number of times one seedling mat is fed in the width direction of the machine) must be input to the lateral feed number input unit 185. be.

In this embodiment, the planting number input section 183, seedling collection amount input section 184, and horizontal feeding number input section 185 are pressed to manually input each numerical value by the operator. In addition, dropdowns 180, 181 and 182 are provided on the right side of the planting number input section 183, the seedling amount input section 184, and the lateral feed number input section 185, and each dropdown 180, 181 or 182 is pressed. In a picker dialog (not shown) that is operated and displayed, it is also possible to select numerical values of the number of plants to be planted, the amount of seedlings taken, and the number of times of horizontal feeding by pressing operations. Therefore, the operator can use the seedling box number calculation unit 179 to easily input or change the information necessary for the terminal 112 to automatically calculate the number of seedling boxes.

Here, in this embodiment, according to the model (model) of the seedling transplanter 1, only candidates for the appropriate number of plants to be planted are displayed in the picker dialog of the number of plants to be planted input unit 183. there is Therefore, erroneous input of the number of plants to be planted can be suppressed. The model can be determined based on data registered in the terminal 112 or by transmitting model-related data from the aircraft to the terminal 112 .

The number of plants to be planted, the amount of seedlings taken, and the number of times of lateral feeding are detected by a sensor, and are automatically input to the number of plants to be planted input section 183, the amount of seedlings taken input section 184, and the number of times of lateral feeding input section 185. You may By configuring in this way, it is possible to prevent erroneous input by the operator and reduce labor. Further, based on the data detected by the sensor, even after automatic input to the planting number input unit 183, the seedling amount input unit 184, and the lateral feeding number input unit 185, input by the picker dialog, or By enabling manual input, even if an incorrect number of plants to be planted, the amount of seedlings taken, or the number of lateral feeds is entered due to reasons such as sensor failure, the operator can correct the entered values. can do.

When the number of plants to be planted, the amount of seedlings taken, and the number of lateral feedings are input as described above, the terminal 112 first calculates the number of seedling boxes used per roll (10a) (the number of seedling boxes and seedling mats used). calculate. The number of seedling boxes used per roll is calculated by the formula: number of plants planted per roll / number of plants planted in one seedling box x ^1.15 , The distance between plants is calculated (determined) from the number of plants per tsubo, and the number of plants planted in one seedling box is calculated (determined) from the amount of seedlings taken and the number of lateral feedings. The calculated number of seedling boxes used per roll is displayed in the seedling box number display section 186 per roll.

After calculating the number of used seedling boxes per roll (10a), when the operator presses the automatic calculation switch 189, the terminal 112 displays the number of used seedling boxes per roll and the planting area display section. By accumulating the work area displayed in 177, the total number of seedling boxes used in the entire field is calculated. It is configured to be input to the input section 176 . In this way, by displaying the number of seedling boxes used in each field and the number of seedling boxes used in one field as a whole, the operator can use it as a guideline when directly inputting numerical values into the seedling box number input section 176. be able to.

In addition, as described above, the number of seedling boxes to be planted, the amount of seedlings taken, and the number of transverse feedings necessary for calculating the number of seedling boxes to be input to the number of seedling boxes input section 176 are input; The automatic calculation switch 189 is configured to be switchable to a state in which it is not displayed on the "work result creation screen" by pressing the seedling box number calculation unit ON/OFF switching unit 188 .

In the present embodiment, the terminal 112 also displays the number of plants to be planted, the amount of seedlings taken, and the number of times of lateral feeding last input to the number of plants to be planted input unit 183, the amount of seedlings taken input unit 184, and the number of times of lateral feeding input unit 185. The data is saved, and when the work results are created next time, the saved data is automatically input to the number of planted stocks input section 183, the amount of seedlings taken input section 184, and the number of times of horizontal feeding input section 185. It is configured. Therefore, the worker does not have to enter these values each time he/she creates a work record.

Furthermore, when the rice planting end switch 154 shown in FIG. , data on the amount of seedlings taken and the number of times of horizontal feeding, and at this time, based on the output signal from the GNSS receiver 130, the newly calculated planting area (numerical value displayed on the planting area display unit 177) is used. Then, the number of used seedling boxes in the entire field is automatically calculated and input to the seedling box number input unit 176 . Therefore, if the values of the number of plants to be planted, the amount of seedlings taken, and the number of times of lateral feeding are not changed by the operator, the automatic calculation switch 189 is not pressed and automatically used for planting seedlings. Since the number of seedling boxes is input, operability is good.

In addition, it is possible to set so that the saved data of the number of planted stocks, the amount of seedlings taken, and the number of times of lateral feeding are not automatically input to the number of planted stocks input section 183, the amount of seedlings input section 184, and the number of times of lateral feeding input section 185. is configured to Therefore, it is possible to prevent a situation in which an erroneous numerical value for the number of plants to be planted, the amount of seedlings taken, or the number of lateral feeding times is set.

Furthermore, when the number of plants to be planted, the amount of seedlings taken, or the number of lateral feedings is changed during the seedling planting work, the terminal 112 calculates the number of seedling boxes used under each condition, and then calculates the number of each seedling. The number of used boxes is summed up, and the number of seedling boxes used in the entire field is displayed on a seedling box number display section 187 and a seedling box number input section 176 per field, or input. Therefore, even if the number of plants to be planted, the amount of seedlings taken, or the number of lateral feedings is changed in the middle, the number of seedling boxes used in the entire field can be accurately calculated. The seedling transplanter 1 according to this embodiment is configured to be able to plant seedlings in a field by being operated by an operator. , and based on preset data, the number of plants to be planted, the amount of seedlings taken, and the number of times of horizontal feeding may be automatically switched to enable the work of one field to be executed. With this configuration, it is not necessary for the operator to change the number of plants to be planted, the amount of seedlings taken, or the number of lateral feeding times in the field each time.

As shown in FIG. 15(b), the chemical input unit 178 includes a herbicide input unit 190 for inputting information about the herbicide used and the application agent used (including insecticides and fungicides). It has an applied agent input unit 191 for inputting information about.

In this embodiment, the operator manually inputs the numerical value of the basic usage amount into the basic usage amount input section 169 of the herbicide input section 190 and the basic usage amount input section 173 of the applied agent input section 191. The herbicide unit setting section 168 and application unit setting section 172 can be set by selecting the unit of usage from various units displayed in the picker dialog by the operator.

Furthermore, in this embodiment, when the worker selects the herbicide used in the work from the master data (“Agrisupport pesticide master”) stored in the terminal 112, the selected in the master data The name of the herbicide obtained is automatically input (set) to the herbicide name input section 192, the basic usage amount to the basic usage amount input section 169, and the unit of the basic usage amount to the herbicide unit setting section 168. configured to be

Similarly, when the operator selects an application agent (including insecticides and fungicides) used in the work from the master data stored in the terminal 112, the selected agent in the master data is selected. The drug name of the drug is automatically input (set) to the drug name input section 193, the basic usage amount to the basic usage amount input section 173, and the unit of the basic usage amount to the application unit setting section 72, respectively. is configured to

Further, the operator selects from the master data, and as a result, the chemical name, basic usage amount, and its unit that are automatically input to the chemical input section 178 are input by the operator to the herbicide input section 190 and the applied chemical. It is configured to be modifiable on the input unit 191 . Therefore, if the master data is incorrect, the operator can correct the data automatically input to the herbicide input unit 190 and application agent input unit 191 . When inputting or correcting the unit of the basic amount to be used in the herbicide unit setting unit 168 and the application unit setting unit 72, the operator selects various items displayed in the picker dialog (not shown). Units of base dosage can be entered or modified by depressing and selecting the appropriate units for the drug used.

In this embodiment, the terminal 112 saves the information on the last herbicide and application agent input to the herbicide input unit 190 and the application agent input unit 191 in the master data so that the next work record can be created. When the rice-transplanting end switch 154 is pressed to shift to the "work record creation screen", the terminal 112 automatically inputs the saved data to the herbicide input unit 190 and application agent input unit. 191. Therefore, it is not necessary for the operator to input the data of the herbicide and application agent each time the work record is created, and the operability is good.

Furthermore, the basic amount of herbicide and application agent automatically input as described above and its unit, the number of seedling boxes used (the numerical value input in the seedling box number input section 176) or the planting area (planting area) The terminal 112 automatically calculates the total amount of herbicide used and the total amount of application agent used, respectively, using the numerical value displayed on the applied area display section 177, and inputs the application amount into the herbicide input section 190 and the application amount. The calculated total usage amount is automatically input to total usage amount input sections 170 and 174 respectively provided in the section 191 .

Specifically, as shown in FIG. 15(b), the number of seedling boxes used during the seedling planting operation is input to the number of seedling boxes input section 176, and the basic amount of application agent used is input to the application amount. In the basic usage amount input section 173 in the section 191, the recalculation switch 175 is pressed while the unit is input (set) to "g/box" in the application unit setting section 172 for setting the basic usage amount unit. is pressed, the terminal 112 automatically multiplies the number of seedling boxes input to the seedling box number input section 176 by the basic usage amount input to the basic usage amount input section 173. As a result, the calculated The total used amount of applied drug is automatically input to the total used amount input unit 174 .

On the other hand, the basic usage amount of the applied agent used is input to the basic usage amount input unit 173, and the unit is "kg/10a", "ml/10a" or "kg/10a" in the application unit setting unit 172 for setting the basic usage amount unit. 1/10a" are input (set), and the recalculation switch 175 is pressed, the planted area displayed in the planted area display section 177 and the basic usage amount input section 173 are entered. The calculated basic usage amount is automatically multiplied by the terminal 112 , and as a result, the calculated total usage amount of the application agent is automatically input to the usage total amount input unit 174 .

Therefore, regardless of whether the basic usage amount is set for each box or for each field area, the total usage amount of the application agent is automatically 174 , the operator can save the trouble of calculating the total used amount of the applied agent and inputting it into the total used amount inputting section 174 .

Further, in the same way, the basic usage amount of the herbicide used is input to the basic usage amount input section 169, and the unit is "kg/10a", "ml/ 10a" or "1/10a" is input (set), and the recalculation switch 171 is pressed, the planted area displayed on the planted area display unit 177 and the basic usage amount are input. The terminal 112 automatically multiplies the basic usage amount input to the unit 169 , and as a result, the calculated total herbicide usage amount is automatically input to the total usage amount input unit 170 . there is Therefore, the operator can save the trouble of calculating the total amount of herbicide used and inputting it into the total amount input section 170 .

In this embodiment, the function of automatically inputting the name of the application agent and herbicide, the basic usage amount and its unit, and the total usage amount into the chemical input unit 178 is performed by the operator on the terminal 112. When the automatic input function is turned off (set so that the function is not exhibited), the recalculation switches 171 and 175 are not displayed on the "work record creation screen".

Therefore, to prevent a situation in which an operator erroneously determines that all data has been entered correctly even though the automatically entered drug data needs to be corrected. can be done.
