Description

The present invention relates to a seed ball planting work machine for planting seed balls such as scallions and garlic and taro in ridges.

As a seedling transplanting machine, as described in Patent Document 1, there is a seedling transplanting machine composed of a seedling supply device that receives a large number of seedlings and goes around, and a seedling planting device that raises and lowers a transplanting cup to plant seedlings in ridges. Since this seedling transplanting machine is also used for planting seed balls such as rakkyo and garlic and satoimo instead of transplanted seedlings, it will be described as a planting work machine for seed balls and the like.

Japanese Unexamined Patent Publication No. 2013-70623

When seed balls such as rakkyo and garlic and taro are planted using a seed ball planting machine, planting marks remain on the ridges, but for some reason the seed balls and taro remain in the soil. Even if the planting fails, there is a planting site that does not sprout after the germination period, and ridges with missing stocks are generated, which reduces the yield.

An object of the present invention is to notify an operator of a seed ball planting error during a planting operation so that additional planting can be performed immediately and no stock ridges are generated.

The above-mentioned problem of the present invention is solved by the following technical means.

According to the first aspect of the present invention, the seed ball supplied to the supply cup (33) of the supply unit (31) is delivered to the planting tool (28), and the planting tool (28) is lowered and inserted into the ridge (U). In the planting work machine for planting seed balls in the soil, a seed ball sensor that detects the seed balls in the planting tool (28) at the timing when the planting tool (28) receives the seed balls from the supply cup (33). (1) is provided, and when the seed ball sensor (1) does not detect the seed ball or detects an abnormality in the throwing posture of the seed ball, a planting defect notification means is provided to notify the operator by an alarm or a stop running. It is a planting work machine characterized by the fact that.

The invention of claim 2 is characterized in that the lumen of the planting tool (28) is sharpened toward the tip, and the seed ball sensor (1) is provided at the position of the inner diameter of the seed ball passing through the standard diameter. The planting work machine described in 1.

The invention according to claim 1 is the planting according to claim 1, wherein when the seed ball sensor (1) detects the seed ball during the ascending operation of the planting tool (28), the planting defect notification means is activated. Use as a work machine.

The plant according to claim 1, wherein the invention of claim 4 is provided with a seed ball supply table (3) inclined downward toward the supply cup (33) on the side portion of the supply unit (31). It will be an attached work machine.

The invention according to claim 5 is the planting work machine according to claim 4, wherein the seed ball supply table (3) is provided with a standard seed ball gauge (4).

The invention of claim 6 is characterized in that the circumferential direction of the supply unit (31) can be reversed and the mounting of the seed ball supply table (3) can be changed to the left and right of the supply unit (31). The planting work machine described in 4.

In the invention of claim 1, the seed ball supplied to the supply cup (33) is supplied to the planting tool (28) and is inserted into the soil of the ridge by the descending motion of the planting tool (28) to be planted. However, when the seed ball sensor (1) does not detect the seed ball at the timing when the planting tool (28) receives the seed ball, the supply of the seed ball to the seed ball 28 has failed, so that the seed ball is planted. By notifying the worker by the defect notification means, the seed ball can be planted on the spot at the planting site to correct the seed ball, and the stock shortage will not be noticed until the sprouting time after the planting is completed.

Further, even if the seed ball has entered the planting tool (28), if the position where the seed ball enters, the posture at the time of entering, or a plurality of seed balls are mistakenly inserted at the same time, the seed ball will be inserted into the planting tool (28). The seed ball sensor (seed ball sensor) can cause such poor planting because it is not planted without coming out of the plant and multiple seed balls are planted in the same place and consumed extra. When 1) is detected, the planting defect notification means is activated to notify the operator, and the planting hole where the planting defect may have occurred is investigated on the spot, and if the planting defect has occurred, the planting is performed. Since the repair work can be performed immediately, the seed balls are properly planted, and the yield and quality of the harvested product can be maintained.

In the invention of claim 2, in addition to the effect of the invention of claim 1, the seed ball supplied from the supply cup (33) to the planting tool (28) is from the large diameter entrance of the planting tool (28). The seed ball moves to the tip side with a smaller diameter, but if the seed ball sensor (1) does not detect the seed ball at the position of the inner diameter of the seed ball passing through the standard diameter, the seed ball is not supplied to the planter (28) or is planted. Since there is a possibility that the tool (28) is clogged on the entrance side and does not fall, the occurrence of planting failure can be confirmed on the spot by notifying the operator with the planting defect notification means. It is possible to promptly confirm the presence or absence of problems and take corrective action.

In the invention of claim 3, in addition to the effect of the invention of claim 1, when the seed ball is discharged into the soil and the seed ball sensor (1) detects the seed ball when the planting tool (28) rises. , The seed ball has not moved into the soil from the planting tool (28), and there is a possibility that the seed ball has been taken out. Can recognize that a position where seed balls are not planted can occur on the spot and a position where multiple seed balls can be planted at the same time can occur, promptly confirm whether there is a problem, and respond to the problem. Will be possible.

In the invention of claim 4, in addition to the effect of the invention of claim 1, the worker can supply the seed ball by sliding the seed ball on the seed ball supply table (3) onto the supply cup (33). Supply work can be done easily.

In the invention of claim 5, in addition to the effect of the invention of claim 4, when the operator guides the seed ball on the seed ball supply table (3) to the supply cup (33), the size of the seed ball is measured as a standard seed ball gauge. By removing the ones that are too large or too small as compared with (4), the occurrence of planting defects can be suppressed.

In the invention of claim 6, in addition to the effect of the invention of claim 1, if the seed ball supply table (3) is placed on the left side of the supply unit (31), the worker can supply the seed ball with his / her left hand. If the ball supply table (3) is placed on the right side of the supply unit (31), the worker can supply the seed ball with his right hand, and can select a supply work that is easy to work according to the dominant hand of the worker.

It is called.

In the planting work machine 10, the front wheels 13 and the rear wheels 14 travel between the ridges so that the traveling machine straddles the ridges U in the field, and the planting device 19 is used at the center position of the upper surface of the ridges U in the left-right width direction. Seedlings are being planted.

A traveling chain case 20 is attached to the vehicle. Therefore, the power in the main transmission case 12 input from the engine 11 is transmitted to the traveling chain case 20.

A pair of left and right rear wheels 14 which are traveling wheels are attached to the left and right outer sides of the rotating tip of the traveling chain case 20, and the aircraft is driven by driving the pair of left and right rear wheels 14. Therefore, the main transmission case 12 is a transmission device that transmits to the rear wheels 14 as traveling wheels.

On the other hand, a front wheel support frame 41 extending in the left-right direction is rotatably provided around a rolling shaft 18 (see FIG. 1) in the front-rear direction at the lower part of the engine mount, and front wheels 13 are provided at both left and right ends of the front wheel support frame 41. It has an attached configuration.

Further, as shown in FIG. 2, a rear frame 21 extending in the left-right direction is fixedly provided at the rear end of the main transmission case 12, and the rear frame 21 is provided at the right end of the rear end surface of the rear frame 21 at a position closer to the right of the aircraft. A main frame 22 extending in the direction is provided. A steering handle 16 is provided at the rear end of the main frame 22, and the steering handle 16 is supported by the main transmission case 12 via the main frame 22 and the rear frame 21. The front lower end portion of the planting transmission case 26 is placed on the upper surface of the rear frame 21 at a position closer to the left and right (to the right), and the planting transmission case 26 is fixedly provided.

Further, a hydraulic elevating cylinder 23 is provided at the center in the left-right direction at the rear of the main transmission case 12. The hydraulic pressure elevating cylinder 23 is fixedly provided to the hydraulic pressure switching valve portion 24 (see FIG. 1) attached to the main transmission case 12, and the oil passage from the hydraulic pump attached to the main transmission case 12 is a hydraulic pressure switching valve. It operates by switching in the unit 24.

Further, a horizontal rod 43 extending to the left and right is provided at the rear end of the cylinder rod of the hydraulic elevating cylinder 23, and the left rear wheel elevating rod 44 and the right rear wheel elevating rod, which serve as rods, are provided at the left and right ends of the horizontal rod 43, respectively. 45 is connected, and the other ends of the left rear wheel elevating rod 44 and the right rear wheel elevating rod 45 are pivotally attached to the upper arm 40a attached to each traveling extension case 40, and the horizontal rod 43 and the traveling extension case are attached. It has a structure in which 40 is connected.

Therefore, due to the expansion and contraction of the hydraulic elevating cylinder 23, the traveling chain case 20 is rotated around the left and right output shafts of the main transmission case 12 via the horizontal rod 43, the left rear wheel elevating rod 44, and the right rear wheel elevating rod 45. The rear wheel 14 moves up and down due to the rotation of the traveling chain case 20, and the traveling machine body moves up and down.

By operating the hydraulic elevating cylinder 23 to control the elevating and lowering of the left and right rear wheels 14, the traveling machine is controlled to a predetermined height with respect to the ridge U, and the planting tool 28 plantes the seedlings in the ridge U at a constant depth. I am trying to be.

Further, a left-right tilt hydraulic cylinder 25 that is operated by hydraulic pressure from a hydraulic pump is provided in the middle of the left rear wheel lift rod 44 so that the left rear wheel lift rod 44 expands and contracts. By expanding and contracting the cylinder 25, the left rear wheel 14 is moved up and down with respect to the vertical position of the right rear wheel 14, and the traveling machine body is controlled to a desired left-right tilted posture.

A pendulum type left / right tilt sensor 42 is provided on the right side of the main transmission case 12, and the left / right tilt sensor 42 detects the left / right tilt sensor 42 for left / right tilt via the left / right tilt switching valve provided in the hydraulic pressure switching valve unit 24. The hydraulic cylinder 25 is operated to control the traveling machine body to a horizontal posture.

The planting device 19 of the first embodiment is a planting transmission case in which power from the inside of the main transmission case 12 is provided on the rear side of the main transmission case 12 in order to plant the scallions seed balls one by one in the ridges of the field. It is transmitted and operated through the planting device drive case 27 attached to the planting transmission case 26 and the planting device 26.

The planting device 19 is composed of a cup-shaped planting tool 28 having a pointed tip and an elevating link mechanism 29 operating to raise and lower the planting tool 28, whose lumen is pointed to a small diameter toward the tip. It is composed. As shown in FIG. 1, the tip of the planting tool 28 descends on the front side and rises on the rear side due to the raising and lowering motion of the planting tool 28, and has a shape in which the width in the front-rear direction is larger in the lower part than in the upper part. The locus 17 is drawn and repeatedly operated in the direction of the arrow in the figure.

As shown in FIG. 4, the planting tool 28 is configured by pivotally supporting the upper ends of the front receiving piece 28A and the rear receiving piece 28B so that the tips open and close back and forth, and after inserting into the soil, the seed ball is opened. I try to close it while leaving it ascending. On the front receiving piece 28A of the planting tool 28, a seed ball sensor 1 that emits a detection means such as a laser beam or an ultrasonic wave is arranged toward the rear receiving piece 28B with the vertical direction of the planting tool 28 as the longitudinal direction. , The presence or absence of the seed ball entering the planting tool 28, and the position of the seed ball in the vertical direction of the planting tool 28 are detected.

As shown in FIG. 4, the seed ball sensor 1 is configured by arranging detection radiators 1a, 1b, 1c, 1d, 1e that emit detection means at predetermined intervals in the vertical direction, and is configured as a rear receiving piece during operation. It is assumed that each emits the detection means toward the inner wall surface of 28B. Then, the presence or absence of the seed ball and the position where the seed ball is thrown are determined by the time until the emitted detection means is reflected and returns to the detection radiators 1a, 1b, 1c, 1d, 1e. It should be noted that each of the detected radiators 1a, 1b, 1c, 1d, and 1e is provided with at least a predetermined interval in the vertical direction in which the detecting means do not interfere with each other in order to detect only the detecting means emitted by the detection radiators 1a, 1b, 1c, 1d, and 1e. do.

When the seed ball sensor 1 does not detect the seed ball or detects the seed ball at a position where it can be determined that the seed ball is abnormal, the planting defect notification means composed of a buzzer, a lamp, or the like is activated to inform the operator of the previous planting. It informs that the seed ball may not be planted or that multiple seed balls may be planted at the same position in the attachment operation.

Even if it is normal, the buzzer or lamp may operate in a certain pattern, and if it is abnormal, it may operate in another pattern. For example, when it is normal, the lamp lights up in green, and when an abnormality is detected, it lights up in red. When it is normal, a short beep is sounded once or multiple times, and the abnormality is detected. When this is done, it is conceivable that a short sound of "pip" is pronounced multiple times at shorter intervals than in normal times, or a long sound of "pee" is continuously pronounced.

Hereinafter, the determination of normality and abnormality when the seed ball is thrown into the planting tool 28 from the supply cup 33 will be described with reference to FIGS. 5A to 5D.

As shown in FIG. 5A, among the plurality of detection radiators 1a, 1b, 1c, 1d, 1e, the fifth detection radiator 1e and the fifth detection radiator 1e located on the lower side of the seed ball sensor 1. And the 4th detection radiator 1d, or the 5th detection radiator 1e, the 4th detection radiator 1d, and the 3rd detection radiator 1c located at the center of the upper and lower parts detect the seed ball, and the seed ball is the planting tool 28. When the planting tool 28 is inserted into the soil and opened, it is in a state where one seed ball can be normally planted, that is, it is judged to be "normal". , The planting failure notification means does not work or notifies the operator that it is "normal".

In addition, since the upper and lower ranges that can be regarded as "normal" differ depending on the type of seed ball to be planted, it is possible to change which detection radiator is used to distinguish between "normal" and "abnormal". It is desirable to do.

On the other hand, as shown in FIG. 5D, when the non-detection state is continued among the plurality of detected radiators 1a, 1b, 1c, 1d, 1e, the seed ball is put into the supply cup 33 in the first place. The seed ball was not supplied because the seed ball was not supplied, the seed ball was stuck in the supply cup 33, the seed ball fell to a position away from the planting tool 28, or the like, that is, "abnormality". Therefore, the planting defect notification means is activated.

Further, as shown in FIG. 5B, among the plurality of detected radiators 1a, 1b, 1c, 1d, 1e, the fifth detected radiator 1e, the fourth detected radiator 1d, and the upper and lower center portions are located. When the second detection radiator 1b to the first detection radiator 1a detect seed balls in addition to the third detection radiator 1c, a plurality of seed balls are thrown in and stacked, or abnormally up and down. Since it is determined that a long seed ball has been thrown into the plant, that is, it is "abnormal", the planting defect notification means is activated.

In the above case, if the first detection radiator 1a is determined to be "abnormal" even in the non-detection state, it is easy to detect the stacking of small seed balls. On the other hand, if it is determined that "abnormality" is detected when all the first detection radiators 1a are detected, it is possible to prevent "abnormality" from being erroneously detected even if the seed balls are large in size unless they are stacked. ..

Then, as shown in FIG. 5C, the first detection radiator 1a or the second detection radiator 1b or the first detection radiator 1a and the second detection radiator 1b located on the upper side of the seed ball sensor 1 When both are in the detection state and the detection radiator below the third detection radiator 1c does not detect the seed ball, the seed ball is largely clogged on the upper side of the planter 28, or due to soil or mucus. Since it is determined that the state is stuck, that is, it is "abnormal", the planting defect notification means is activated.

In the above example, the condition is that the 4th detected radiator 1d and the 5th detected radiator 1e are not detected, but the 1st detected radiator 1a and the 2nd detected radiator 1b are in the detected state. Moreover, even when any of the third detection radiator 1c to the fifth detection radiator 1e does not detect the seed ball, the seed ball is clogged or stuck to the upper side of the planting tool 28 and is planted. Even if the attachment 28 is inserted into the soil and opened, it will not fall into the soil, or the planting tool 28 will close as it rises during the fall, and it may be taken back without being planted in the soil. It is necessary to activate the planting defect notification means.

Further, even if the seed ball enters the planting tool 28 and moves to the lower side, even if it is finally judged to be "normal", the first and second detections located on the upper side during the fall. Only the radiators 1a and 1b are in a state where the seed ball can be detected and judged as "abnormal". May be misunderstood. Therefore, the plurality of detection radiators 1a, 1b, 1c, 1d, 1e constituting the seed ball sensor 1 transmit a signal only when the seed ball is continuously detected for a predetermined time (eg: 1 to 2 seconds) or longer. These signals shall be received by the control device and it shall be determined whether they are "normal" or "abnormal".

Based on the above, depending on the presence / absence of notification of the planting defect notification means or the notification pattern, the operator can determine whether or not the seed ball has been normally taken over from the supply cup 33 to the planting tool 28 even while the seed ball is being input. It can be known before the planting tool 28 is planted in the soil. As a result, when there is a possibility that a planting defect has occurred, the work can be interrupted on the spot, and the inside of the planting hole formed by the planting tool 28 on the ground can be examined to confirm the presence or absence of seed balls and the number of seed balls. ..

Where there are "abnormalities" such as no seed balls or two or more seed balls, the worker can manually plant the seed balls on the spot or collect other seed balls to make one. Therefore, it is not necessary to check each planting hole after the planting work of the entire field is completed, which reduces extra time and labor, reduces crop growth and reduces yield, and multiple seeds. It prevents the spheres from growing at the same time and competing for nutrients, resulting in poor quality crops.

Since seed balls such as taro germinate and root from the state of being placed in the soil, there is no problem in growth even if the seed balls are taken out from the planting hole and refilled.

The seed ball sensor 1 is a section from the time when the seed ball is planted in the soil by the planting tool 28 to the time when the next seed ball is received from the supply cup 33, that is, from the vicinity of the bottom dead center of the planting tool 28 to death. Up to the vicinity of the point, there is no detection target, and if it is left as it is, it will be judged as an "abnormality" without a seed ball and the planting failure notification means will continue to operate, but an abnormality is detected in the section where it is normal that there is no seed ball. Continuing to do so can cause confusion for workers and can also generate noise in the surrounding environment.

In order to prevent this, the elevating link mechanism 29 that moves the planting tool 28 up and down while drawing a planting locus and opens and closes before and after fitting into the soil is provided with a link sensor 50 that detects the elevating position. .. The link sensor 50 is, for example, a potentiometer connected to a control device, and transmits the current rotation position of the elevating link mechanism 29.

Then, the control device determines that the rotation position of the elevating link mechanism 29 detected by the link sensor 50 is located near the top dead center or near the top dead center where the planting tool 28 receives the seed ball from the supply cup 33. , The seed ball sensor 1, and more specifically, the presence or absence of the seed ball entering the planting tool 28 by operating the plurality of detection radiators 1a, 1b, 1c, 1d, 1e constituting the seed ball sensor 1, and the seed. The position of the sphere is detected and it is judged whether it is "normal" or "abnormal".

As a result, even if the seed ball is planted in the soil and there is no seed ball in the planting tool 28, the seed ball is then planted up to the top dead center and the position near the top dead center where the seed ball is taken over from the supply cup 33. Since the defect notification means does not operate, it is less likely that the operator will be mentally burdened, and the generation of noise can be prevented.

Further, since the seed ball sensor 1 continues to operate while the planting tool 28 takes over the seed ball and descends, the seed ball moves from the upper position to the lower position of the planting tool 28 due to the descending movement of the planting tool 28. If it falls and switches from "abnormal" to "normal", the planting failure notification means can be stopped or the operation pattern can be changed to notify the operator that "normal" planting is being performed. , The frequency of interrupting work is reduced, and work efficiency is improved.

In the above example, it is premised that the seed ball is surely planted if it is in a position determined to be "normal" in the planting tool 28 by the time it is planted. However, when the seed ball has the property of leaking mucus such as taro, or depending on the conditions such as the presence of stones in the soil, the seed ball may stay in the planting tool 28. At this time, the link sensor 50 determines that the elevating link mechanism 29 is taking an ascending angle, and the control device stops the seed ball sensor 1. Therefore, at least the operator takes over the next seed ball and the planting tool. Until the 28 descends, a plurality of seed balls are detected in the planting tool 28, and the planting failure notification means is activated, the seed balls are not noticed in some places.

In order to prevent this, the control device does not stop the seed ball sensor 1 at the bottom dead center where the planting tool 28 plants the seed ball in the soil and starts to rise, or at a position near the bottom dead center, and the link sensor 50 causes the link sensor 50. The seed ball sensor 1 may be stopped when the upward rotation angle of the elevating link mechanism 29 to be detected becomes a predetermined value or more.

However, the seed ball is likely to be located near the lower side of the planting tool 28, and is judged to be "normal" under the above-mentioned determination conditions. Any one of the plurality of detected radiators (1a to 1e) is detected until the set angle considered to be located near the bottom dead center is detected and then the predetermined upward rotation angle of the elevating link mechanism 29 is detected. When the seed ball is detected, it is determined that the planting tool 28 is "abnormal" in which the seed ball is brought back, and the planting defect notification means is activated.

As a result, it is possible to notify the worker that the seed ball was not planted on the spot, so that the work can be interrupted and the seed ball can be planted manually. In addition to this, it is possible to prevent multiple seed balls from being planted at the next planting position, which reduces the time and labor required for replanting the seed balls.

In this situation, it is structurally difficult to take out the seed ball brought back by the planting tool 28, and if it is forcibly taken out, the seed ball may be damaged or the planting tool 28 may be damaged. It is desirable to take out the seed balls from the supply cup 33 to be supplied by dropping and to plant the seed balls brought back without throwing in a plurality of seed balls. If there is a possibility that the seed balls are stuck due to the mucus, it is advisable to pour water into the planting tool 28.

The relationship between the devices related to the above control is shown in FIG. 6, and the control procedure is shown in FIGS. 7 and 8.

The size of the planting tool 28 needs to be changed depending on the type of seed ball to be planted, and the taro often stays on the upper part of the planting tool 28, so it is necessary to carefully perform the transplanting work.

The lower front part of the planting tool 28 is provided with a hole making body 110 that forms a shallow concave hole in the field around the planted seedling when the seedling is planted by the planting tool 28. The hole-making support frame 111 that supports the hole-making body 110 at one end is rotatably attached to the main frame 22 at the other end so that the hole-making body 110 can move up and down.

Further, a hole-making support shaft 112 is connected to an intermediate portion of the hole-making support frame 111, and when the hole-making support shaft 112 moves up and down, the hole-making support frame 111 is moved up and down to form a hole-making body. The vertical movement of 110 is controlled.

FIG. 3 is a bottom view of the supply unit 31, which is a seedling supply unit, as viewed from below.

As shown in FIG. 2, in the supply unit 31, a supply cup 33, which is operated by power from the planting transmission case 26 and for the operator to manually supply the seedlings one by one, is circular on the supply rotary table 32. It is arranged in a loop shape at predetermined intervals. The supply unit 31 is supported by a seedling supply support frame F whose base is fixed to the planting transmission case 26.

As shown in FIG. 3, the bottom of each supply cup 33 is provided with one opening / closing lid 34 that can move in the vertical direction.

Further, as shown in FIG. 3, below each supply cup 33, the supply cup 33 comes to a predetermined position P, which is a position above the planter 28, due to the rotation of the supply rotary table 32 in the direction of the arrow A. A substantially C-shaped supply cup opening / closing guide 35 having a part of the ring cut out is fixed to the traveling machine body side so that the opening / closing lid 34 at the bottom of the supply cup 33 can be opened only when the supply cup 33 is used. The supply cup opening / closing guide 35 restricts the opening / closing lid 34 from opening by contacting and supporting the opening / closing lid 34 from below at a position other than the predetermined position P.
