Abstract

PURPOSE:To provide a vegetable transplanter enabling both transplantation and irrigation in high efficiency for a long period of time, so designed that irrigation nozzles are set up outside a transplanting claw and irrigation is conducted during the transplanting claw's rising in an opened state to conduct seedling irrigation and transplanting claw washing simultaneously. CONSTITUTION:Firstly, seedlings are fed from the rotary seedling feeder on the upper part of the machine body to a transplanting claw followed by lowering the transplanting claw. Second, transplanting holes are made in the soil of a farm using this claw along with opening the claw parts 1a, 2a to plant seedlings. Third, in raising the planting claw in an opened state, an irrigation is conducted from irrigation nozzles 7, 7 set up outside the claw to wash away the soil and sand attached to both the inside and outside of the claw parts 1a, 2a along with applying the water dropped along the claw parts 1a, 2a to the seedlings. The water to be applied is fed, for example, from a water tank via an irrigating hose 10 to the nozzles 7, 7 through an irrigation pump.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an irrigation device and a chemical spraying device in a self-propelled vegetable transplanter.

[0002]

2. Description of the Related Art Conventionally, in an irrigation device to be mounted on a vegetable transplanter, the irrigation nozzle is located at a position different from the nail for irrigation and irrigates separately from the transplanting work.
If it is provided at the same position as the transplanted nail, it should be
30888, Jikkou Sho 63-30890, or Jikken 2
As described in 36334, the nozzle is fitted into the transplanted nail so that water is ejected into the transplanted nail when the transplanted nail is opened or stuck into the soil, and As in Japanese Examined Patent Publication No. 62-61287, there is a configuration in which the water is jetted below the shutter by being positioned outside the guide cylinder.

Further, in a drug spraying device, a technique of intermittently spraying a drug at a transplantation position on a field before transplantation in synchronism with the raising and lowering movement of a transplanted nail is disclosed in Japanese Utility Model Laid-Open No. 63-2071.
0, Jikkou Sho 57-46730, or Japanese Examined Patent Publication 4-202
32, etc., and regarding the position of the spraying port of the drug granulation tube, see S. 63-15712 and S. 52.
─109112, and as described in Japanese Examined Patent Publication No. 4-20232, it was located at the front end of the body of the transplanter.

[0004]

In contrast to the above-mentioned conventional techniques, first, in a vegetable transplanter equipped with a watering device,
Since the work of inserting the transplanted nail into the soil in the field, opening the nail and transplanting the seedlings is repeated, the soil for the transplanted nail is attached and deposited. If the attached soil becomes excessively large, the opening of the transplant hole on the field by the nail and the opening drive of the transplant nail itself become insufficient, and transplantation may not be successful. In the above-mentioned conventional technique, the attached soil on the inside of the transplanted nail is washed, but the attached soil on the outside is not washed. Therefore, it is desirable to wash away the soil adhering to the inside and outside of the nail for each transplant, and it is desirable to use the irrigation water of the irrigation device attached to the machine body as the washing water.

Next, in a vegetable transplanter equipped with a drug spraying device, a drug is conventionally sprayed intermittently, and the drug granulation tube itself is positionally fixed to the machine body. However, in the drug spraying work during transplantation, the aircraft itself continues to advance even during the spraying, and in order to spray a certain amount of the drug, the drug is sprayed for a certain period of time. The spraying position moves forward with the forward movement of the airframe, forming a strip (flowing in the front-back direction). This is inefficient because it overlaps with the implantation position and the effect of the drug on the misaligned portion is weakened. Therefore, it is desired to have a structure in which the drug is sprayed intensively at one point regardless of the forward movement of the airframe. Further, the nozzle position has conventionally been at the front end position of the machine body and separated from the transplant nail, but in order to match the drug spraying position and the transplant position, the distance between both positions is large. When,
Since errors are likely to occur, it is desirable to bring them as close as possible.

[0006]

The present invention uses the following method in order to solve the above problems. That is, in a vegetable transplanter that raises and lowers the transplanted nail and transplants the pot seedling placed on the upper part of the machine onto the field, arrange a irrigation nozzle outside the transplanted nail and irrigate when the opening of the transplanted nail rises. In addition, a drug granulation tube that swings back and forth in synchronization with the raising and lowering of the transplanted nail is arranged in front of the transplanted nail, and is configured to spray the drug in accordance with the forward movement of the machine. The machine is configured to continuously perform the chemical spraying and the watering in the same process.

[0007]

The operation of the present invention constructed as above will be described. In the vegetable transplanter equipped with the irrigation device of the present invention, when the transplanted nail A is opened and raised after transplantation, irrigation is performed from the irrigation nozzles 7 on both left and right sides of the transplanted nail, Irrigation is applied to the front side and the back side of the claw portions 1a and 2a of A, and the attached sand is washed away.

Further, when the medicine spraying device is mounted, it is attached to the adjusting link 15 via the granulating tube support 23, or to the burner support 40 and the granulating tube support 45 or 46. In any of the cases, the spraying port of the drug dispersion tube 24 is located immediately in front of the transplant nail A, and sprays when swinging backward, so that the spraying position is in one place in combination with the forward movement of the aircraft. Focus on dots.

Further, springs 5 are interposed between the left and right upper ends of the sleeve portion 4 and the pivot shafts 3 to correct the wobbling of the front claw body 1 and the rear claw body 2.

Next, the structure of the seedling feeding section will be described. On the upper part of the machine body, a rotary seedling feeding device B constituting a seedling feeding portion is arranged behind the bonnet 53. As shown in FIG. 12, in the rotary seedling feeding device B, seedling seeding sleeves 32 are radially arranged on the rotating body 31, and the seedling seedling sleeve 32 is formed in a C shape on the outer periphery of the seedling feeding sleeve 32 toward the rear of the machine. An open guide rail 35 is provided. The rotating body 31 is, as described above,
It is transmitted from the transplantation drive shaft 25 of the transplantation transmission case D via a chain 30 and is rotationally driven. The seedling feeding plate 33 is pivotally connected to one point of the bottom edge of the seedling feeding sleeve 32, and the springs 34 are connected to the central portion of the rotating body 31, respectively. Although the seedling feeding plate 33 closes the bottom of the seedling feeding sleeve 32 by pressing the guide rail 35, the rotating body 31 rotates and the seedling feeding is performed on the rear portion of the rotary seedling feeding device B where the guide rail 35 does not exist. When the sleeve 31 reaches the seedling feeding plate 33, the guide rail 35 is no longer pressed against the seedling feeding plate 33, and at the same time, the seedling feeding plate 33 is rotated by a spring 34 urged to the center of the rotating body 31 to feed the seedlings. The bottom of the sleeve 32 is open.

In the transplanting nail A, the vertically swinging link L, and the rotary seedling feeding device B having the above-mentioned structures, during transplanting work,
Put pot seedlings in seedling feeding sleeve 32 and rotate seedling feeding device B
The rotating body 31 of the same is synchronized with the transplant nail A (the transplant drive shaft 25
When the seedling feeding sleeve 32 reaches the rear position of the rotating seedling feeding device B, the seedling feeding sleeve 32 is rotated.
Since the bottom of the seedling is opened and the transplanted nail A is in the raised position at this time, pot seedlings are seeded in the transplanted nail A from the seedling feeding sleeve 32. Then, the vertical swinging link L provided with the transplanted nail A descends, the transplanted nail A containing the seedling reaches the field, and a transplant hole is opened in the soil, and the nail portion of the transplanted nail A is opened. Then, the seedlings are planted in the transplanting holes in the field, and the transplanting nails A are lifted again as the vertical swing link L is raised, and are separated from the transplanted seedlings, and the transplantation at the transplanting position is completed.

Next, the structure of the irrigation system will be described.
The watering device is a device for watering the transplanted seedling portion,
As shown in FIG. 13, the water supply tank T1 is above the vegetable transplanter,
It is arranged at the left front position of the rotary seedling feeding device B. Then, the irrigation hose 10 is extended from the water supply tank T1 via the irrigation pump 36, and the tip portion is attached to the irrigation nozzles 7 as shown in FIG. The irrigation nozzles 7 and 7 are supported on both ends of the nozzle support 7a, and as shown in FIGS. 2 to 4, the irrigation nozzles 7 are inserted into the fitting plate holes 2b of the rear nail body 2 of the transplant nail A. Vertically adjusting bolts 8 and 8 protruding from the nozzle support 7a are fitted and fixed by interposing nuts 9 and 9, and the nozzle support 7a is fitted along the claw portion 2a of the rear claw body 2, The irrigation nozzles 7, 7 are located on the left and right sides above the claws 1a, 2a.

The irrigation timing is when the transplanted nail A opens and rises, and irrigation is applied to the outside and the inside of the nails 1a and 2a of the transplanted nail A, and soil attached to both inside and outside of the nails 1a and 2a. The seedlings are drained off, and further fall along the nails 1a and 2a to irrigate the transplanted seedlings. Then, as shown in FIG. 13, the irrigation is performed by pressing the pressing portion 36 of the irrigation pump 36.
When a is pressed against the rotating seedling sleeve 32 on the rotary seedling feeder B and pushed in, and the piston connected to the pushing portion 36a is pushed inside the pump, the pump operates. Water is supplied into the irrigation pump 36 when the pushing portion 36a is released, and the seedling sleeve 32 is pushed by moving the adjusting lever 37 inserted into the long hole of the adjusting plate 37a. It adjusts the timing.

Next, the structure of the drug spraying device will be described. The drug spraying device is a device for intensively spraying a drug at a predetermined position for transplantation before transplanting seedlings. First, as shown in FIG. 13, the medicine tank T2 is disposed in the upper part of the vegetable transplanter, to the left front of the rotary seeding apparatus B, and the limit switch 38 is provided.
Is arranged so as to be pressed against the rotating seedling sleeve 32 and turned on. A motor is built in the medicine tank T2, and the driving force of the motor is due to the battery 58 attached to the front end of the vegetable transplanter as shown in FIG. And
When the limit switch 38 is turned on, the feeding device is driven to send the medicine to the granulation tube 24.

The sprinkling port of the granulating tube 24 is the descending nail A
It is supported so that it is located just in front of. That is, the upper end of the granulating tube support 23 whose vertical length can be adjusted is fixed to the mounting portion 15a of the adjusting link 15 pivotally supported by the vertical swinging link L, and the granulating tube 24 sprinkling port is provided at the lower end. Is to support. As shown in FIG. 5, the adjustment link 15 rotates backward when the vertical swing link L swings upward, and rotates forward when it descends. That is, the spraying port of the granulating tube 24 fixed to the adjusting link 15 swings back and forth as the vertical swinging link L swings, that is, as the transplanting nail A moves up and down. When the nail A rises (arrow X '), the spray port swings from the front to the back (arrow X), and when the nail A descends (arrow Y'), it swings from the back to the front (arrow Y). Of.

By the way, the vegetable transplanting machine continues to move forward even while a certain amount of the drug is sprayed from the spraying port for each spraying. In such a case, if the granulation tube 24 is fixed in position with respect to the machine body, the sprayed drug will be in the form of a band, and the spraying amount at the transplantation predetermined position will be small, and a large amount will be sprayed to unrelated positions. Is inefficient. However, in this embodiment, the granulating tube 24 swings back and forth as described above, and if the medicine is sprayed when moving backward (arrow X) with respect to the machine body, the machine body advances. Combined with this, the drug can be dispersed in a spot-like manner at a predetermined position. That is, the timing of spraying the drug is adjusted to the time when the transplanted nail A is raised (arrow X ′). In addition, as for the mounting posture of the granulating tube support 23, the rear part faces upward, and since it is sprayed when moving backward, the granulating tube 2
The spraying port of No. 4 is opened forward so that the spraying is smooth.

And, as described above, the chemical spraying is performed based on the ON of the limit switch 38.
By adjusting the mounting position of the limit switch 38, the spraying timing is adjusted when the transplanted nail A is raised. The limit switch 38 is fixed to the stay 38a with bolts 38b and 38b.
By loosening 8b and adjusting the mounting angle of the limit switch 38, the pressing timing of the switch is adjusted. Further, since the spray port of the granulating tube 24 is located immediately before the transplant nail A, there is no other spray portion between the drug spray portion immediately after spraying and the position of the transplant nail A at that time, that is, Since the transplant nail A immediately descends to the sprayed portion to perform transplantation, even when adjusting the spraying timing of the drug, a timing error is unlikely to occur and the adjustment is easy.

Next, the structure for attaching the spraying port of the drug granulation tube to the support of the multi-hole opening burner will be described with reference to FIGS. 7 to 11. The multi-hole opening burner 39 shown in FIG. 9 is used when the multi-film is laid on the ridges.
A hole for transplantation is opened in the mulch film immediately before transplantation, and a cylinder (not shown) is mounted on the machine body, and a multi-hole is opened by spraying and burning when the burner descends. Then, in order to positionally fix the multi-hole opening burner 39 in front of the transplant nail A, a burner support tool 40 is used.
Is attached below the lower link 18. First, the burner support 40 has a U-shaped pivotal support 40a in a plan view.
Is pivotally supported on the front nail body 1 of the transplanted nail A, and the spring 41 is connected from the lower link 19. In addition, the pivotal support portion 1 of the front nail body 1
In c, a stopper 42 (not interfering with the pivoting bolt of the lower link rear end 18a) is provided so as to be able to abut on a bolt that pivotally connects the upper link rear end 17a, and a roller 43, a roller 43 A burner mounting portion 44 is mounted in front of the roller 43 on the burner support 40 so that the front and rear positions thereof can be adjusted.
Is fitted and fixed below the burner mounting portion 44. The vertical length of the multi-hole opening burner 39 can be adjusted.

In the burner support 40, as shown in FIG. 7, when the transplanted nail A is in the raised position, the roller 43 presses the lower part of the lower link 18 by the downward urging force of the spring 41, so that the burner is supported. The support 40 does not interfere with the lower link 18 and is fixed in position. Then, at the lowered position of the transplanted nail A, the rear end of the lower link 18 descends downward, but as shown in FIG. 8, the stopper 42 presses against the pivoting bolt of the upper link rear end 17a, The rear end of the burner support tool 40 is restricted from rotating downward,
By holding the spring 41, the burner support 40 is held horizontally, so that the multi-hole opening burner 39 is
Make holes in the mulch film accurately.

In this embodiment, a support for the drug granulation tube 24 is attached to the burner support 40, as shown in FIG.
When using together with the multi-hole opening burner 39, a granulation tube support 45 is attached between the burner fitting 44 and the roller 43 so as to be slidable forward and backward, and the granulation tube can be adjusted vertically. 24 spray ports are attached. And, FIG. 10 shows a structure in place of the multi-hole opening burner 39.
The granulating tube support 46 is fitted and inserted below the burner mounting portion 44, and the spraying port of the granulating tube 24 is mounted so that its vertical position can be adjusted.

In the medicine granulation tube 24 thus mounted, as shown in FIG. 7, in the same manner as in the embodiment in which the granulation tube support 23 is mounted on the adjusting link 15 as shown in FIG. The spraying timing is adjusted so that the drug is sprayed when the transplanted nail A, which is moved backward, is lifted,
Further, similarly to the case of directing the spraying port forward, the medicine can be sprayed to one point in a concentrated manner regardless of the forward movement of the machine, as in the above-described embodiment.

[0029]

The present invention has the following effects by being configured as described above. That is, in the vegetable transplanter, the irrigation nozzles of the irrigation device are attached to the left and right outer positions of the transplanted nail, and water is applied when the transplanted nail opens and rises. The soil adhering to the soil can be washed away, and a long-term efficient transplantation and irrigation work can be obtained without causing the functional deterioration of the transplanted nail.

Further, since the granulation tube of the medicine spraying device can be swung back and forth and the medicine is sprayed when moving backward with respect to the forward movement of the machine, the medicine is sprayed at a predetermined position in a dot-like manner, and seedlings are seeded. The growth of the drug is good, and the drug can be efficiently sprayed without waste. Furthermore, since the spray port of the drug granulation tube is located immediately in front of the transplant nail, the spray position of the drug and the transplant position can be improved. The error with the position is unlikely to occur, and it is easy to adjust the spray timing.

Further, by mounting both the irrigation device and the chemical spraying device configured as described above on the vegetable transplanter, the irrigation and the chemical spray can be performed at the same time as the transplanting work, and the work is efficient and the period can be shortened. The growth of seedlings is also very good.
