BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling mounting table which reciprocates in a lateral direction, an apron for receiving seedling bed soil in the seedling mounting table, and an intrusion into the seedling mounting table through a scraping opening of the apron. Then 1 seedling
The present invention relates to a seedling guide device for a transplanter having a planted body that is scraped into individual plants and planted in a field.

2. Description of the Related Art Conventionally, a block-type seedling is cultivated in a pot-type nursery device with a front and rear and a left and right sides, and this block-shaped seedling is stored in a seedling mounting table and a resistance rod is provided on the side better than the delivery section. When seedlings are sent out intermittently, one row of seedlings passes through the resistance rod and is sent out, and the seedlings of the seedlings in this front row are provided over the entire width of the upper side of the seedling table on the sending side. Then, the receiving part, which has a semicircular shape in plan view, is divided and received by the receiving body that is continuous in a corrugated form. A transplanter in which one strain is scraped off and planted in a field is already known from Japanese Patent Application Laid-Open No. 62-208208.

[0003]

In the known transplanter, the seedlings of the seedling block fed up to the sending section of the seedling table are held at the supplied position without changing the relative position of the seedling table. You can do it. However, while the seedling table containing the seedlings moves laterally with a considerably steep posture toward the sending part, the apron that receives the bed soil is attached to the fixed frame so that it does not move laterally. Moves laterally at almost the same speed in synchronization with the lateral movement of the seedling table, but the lateral movement of the bed soil strongly pressed against the apron is delayed due to frictional resistance. Inclining in the direction of movement of the stand and the soil at the scraping end becomes slanted following the inclination of the seedlings, and as a result, the seedlings are cut or pushed down when the planting plant scrapes the seedlings. It caused spilled seedlings and fallen seedlings. In order to solve such a problem, if a seedling guide body that straddles the apron's scraping port and contacts the seedling body and suppresses its movement is attached to a member integrated with the machine body, one seedling stock When the apron is adjusted back and forth to change the size of the seedling, the contact of the seedling guide body with the seedling becomes excessive or insufficient.

[0004]

According to the present invention, an apron having a scraping port is provided at the lower end of a seedling table which is reciprocally moved in the lateral direction and is inclined downward in the delivery direction. In a transplanter in which the seedlings are invaded from the mouth to scrape one plant by one plant and are planted in a field, the apron has a stem or a leaf portion of the seedling that straddles the scrape. The above-mentioned problem was solved by attaching a seedling guide body that comes into contact with the plant and suppresses lateral movement.

[0005]

[Function] When the seedlings with bed soil are stored in the seedling mount and the machine is run while driving the plant and the seed mount, the plant enters the seed mount through the scraping opening of the apron. The seedlings are scraped off one by one and planted in the field. At that time, the leaves and stems of the seedlings move laterally following the lateral movement of the seedling mounting table, but because the bed soil is pressed against the apron, it causes a delay in movement due to resistance, resulting in leaves and stems. Moves laterally in an inclined posture that leads the soil. When the leaves and stems approach the apron scraping opening, they contact the seedling guide body and are restrained from lateral movement. It is in a vertical standing posture, the scraping edge of the floor soil is not slanted, the planter does not cut off the leaves and stems, the planter firmly holds the floor soil, and the spilled seedlings It does not cause fallen seedlings. Further, when the apron is adjusted forward and backward, the seedling guide body advances and retracts integrally with the apron, so that proper seedling leaf movement suppression can be performed regardless of the amount of scraping.

An embodiment of the present invention will be described with reference to a passenger transplanter shown in the drawings. An engine 4, a mission case 5 and a driver's board 6 are provided in front of a main frame 3 of the machine having front wheels 1 and rear wheels 2. And a driver's seat 7 is provided at the rear of the main frame 3, and a planting device 8 is provided at the rear of the main frame 3 as a top link 9
And the left and right lower links 10, 10 and the hydraulic cylinder 11 are connected so as to move up and down.

The power of the engine 4 is distributed by the transmission case 5 to the front wheels 1 and the rear wheels 2 and the planting device 8, and the planting device 8 is driven by a horizontal shaft extending from the transmission case 12 to both sides. Driven by a plurality of planted transmission cases 13 and a rear part thereof and driven by the forks 1 on the beak 15a.
A plurality of planted bodies 15 ... Attached with 5b, a plurality of floats 14, a laterally reciprocating forward tilted seedling mounting table 16 for accommodating seedlings with floor soil, and the seedling mounting table Delivery belt 1 provided at the bottom of 16 and driven intermittently at the lateral movement end
7 and an apron 2 having a scraping opening 18 which is arranged at the delivery portion of the seedling placing table 16 and faces the plant 15
It is composed of 0 and.

Further, the rectangular tube portion 2 at the base portion of the apron 20.
1 is fixed to the planted transmission case 13 and is screwed to a lateral apron stay 22 so that the amount of scraping of the planted body 15 can be adjusted so that it can be moved back and forth. Stand 1
The stay 23 that is erected on the upper surface of the side wall that divides the seedling mounting portion of 6 has a seedling holder 2 that receives the leaf portion of the seedling.
It is installed by mounting 5 in the lateral direction.

The base of the support 27, which receives both sides of the scraping opening 18 of the apron 20 and has a scraping opening 27c, has a bolt 27 at the bottom plate 20a of the apron 20.
The seedling guide body 26 is made of a flexible plate and protrudes toward the seedling platform 16 side in an isosceles triangle shape, and the beak 15a of the planting body 15 passes through the center rear portion. Has a rearward facing opening 26a for forming a reverse L shape in a side view, and the hanging parts 26b, 26b on both sides of the seedling guide body 26 are provided on the support 27 with screws 27b,
It is screwed by 27b, and in this screwed state, the tip of the seedling guide body 26 is formed so as to project slightly forward from the lower end of the seedling holder 25, and is attached to the bracket 28 integral with the apron stay 22. A shooter 32 for guiding the seedlings to be scraped off and planted by the body 15 is screwed by bolts 30 and nuts 31.

At the center of the upper front edge of the seedling guide body 26, the front edge has an isosceles triangular shape and has a seedling holder 25.
A receiving member 35 made of a slippery material such as a synthetic resin that comes into contact with an extension plate 33 hanging from the apron 20 is fitted and fixed, and when the apron 20 is pushed from the position shown by the solid line in FIG. , Seedling guide body 26 and receiving material 35
Bends as shown by the chain line, and the seedling guide body 26 appropriately suppresses the movement of the seedling leaves received by the seedling holder 25. However, the stay 23 of the seedling holder 25 is attached to the apron 20 or the support 27, and the seedling holder 25 is attached to the apron 2.
In the case of advancing and retreating with 0, the relative position between the receiving position of the seedling holder 25 and the movement suppressing portion of the seedling guide body 26 does not change, so that it is not necessary to mount the receiving material 35.

In the above-mentioned transplanting machine, when mat seedlings are stored in the seedling mounting table 16 and the machine is run while the planting device 8 is driven, the seedling mounting table 16 reciprocates in the lateral direction and the rotary type planting is performed. The attached body 15 ... Invades the scraping opening 18 of the apron 20 into the seedling placing table 16 to scrape the soil for one plant and plant it in the field. When the seedling placing table 16 reaches the lateral movement end, Similarly to the above, the delivery belt 17 is intermittently rotated to deliver the mat seedlings until the bed soil presses against the apron 20.

During such planting work, the seedling placing table 16 is in a forward tilted posture, and the floor soil is biased down by its own weight and its lower end surface is pressed against the apron 20 integral with the machine body. When the seedling mounting table 16 moves laterally, the delivery side end surface of the bed soil causes a transfer delay due to frictional resistance, while the leaves are received by the seedling holder 25 and the extension plate 33 which are integrated with the seedling mounting table 16. Therefore, it moves laterally in synchronism with the seedling placing table 16 without causing a transfer delay, and as a result, the leaves are in an inclined posture preceding the bed soil, and the floor soil is stepped. When the seedling is in a deformed state in which the upper part precedes with the tilted posture of the seedling, above the scraping port 18, the tip end of the seedling guide body 26 has entered the seedling mounting table 16. And the receiving material 35 receives the leaf portion on one of the slopes and laterally moves it. As a result, the direction of the seedlings is corrected to a direction that substantially coincides with the rotation surface of the planting body 15 ..., and the scraping end of the bed soil is also kept in a normal shape accordingly. When the attached body 15 scrapes off the ground soil, cuts leaves and stems, and when the beak 15a scrapes and sandwiches the ground soil,
The seedlings will not be caught in an oblique posture or fall off and fall into seedlings.

Further, when the seedling placing table 16 moves laterally in the opposite direction, the seedling guide body 26 and the receiving material 35 receive the leaves by the slope on the other side and suppress the lateral movement, so that the same condition as the above-mentioned condition is obtained. You can scrape off the seedlings. Furthermore,
To increase or decrease the amount of seedlings scraped by the plant 15, apron 2
When 0 is adjusted forward / backward, the seedling guide body 26 moves the apron 20.
Since the seedling guide body 26 advances and retreats together with the apron 20, the seedling guide body 26 restrains the movement of the seedling leaves at a position where it has entered the seedling mounting table 16 from the advanced and retracted apron 20 for a certain length, regardless of the amount of seedling scraping. You can always correct the seedling posture.

[0014]

As described above, according to the present invention, the apron 20 having the scraping port 18 is provided at the lower end portion of the seedling placing table 16 which reciprocates in the lateral direction and descends and slopes in the feeding direction as described above. In a transplanter in which 15 is introduced into the seedling mounting table 16 from the scraping opening 18 to scrape the seedlings one by one and to plant them in the field, the apron 20 is crossed over the scraping opening 18. Since the seedling guide body 26 that suppresses lateral movement by contacting the stem or leaf of the seedling is attached, the leaves and stems of the seedling are almost the same as the seedling mounting base 16 when the seedling mounting base 16 is laterally moved. In contrast to the horizontal movement in the state, the floor soil is pressed against the apron 20 and receives a large resistance, which causes a delay in movement. As a result, the leaves have an inclined posture leading the floor soil.
The seedling guide body 26 arranged on the scraping opening 18 of the plant comes into contact with the seedling leaves and suppresses the movement thereof, whereby the direction of the seedlings is corrected to a posture in which the seedlings are substantially upright from the ground soil, and the planting body. 1
When 5 ... enters the seedling mounting table 16 through the scraping opening 18 and scrapes off the soil, the leaves and stems of the seedlings are not cut, and the soil is broken and seedlings are spilled or grasped. It will not spoil and produce seedlings. Moreover, if the apron 20 is adjusted to move forward or backward in order to change the amount of seedlings scraped by the planting body 15, the seedling guide body 26 will also move forward and backward following the apron 20, thereby reducing the size of the seedlings scraped. Regardless, it is possible to reliably prevent the collapse of the soil and the mistake of grasping.
