Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a rice transplanter in which a seedling placing table composed of a plurality of seedling placing portions is installed obliquely so as to be capable of horizontal reciprocating movement, and in particular, to the above seedling placing portion. The present invention relates to a seedling stand in a rice transplanter that can smoothly slide down a plurality of mat-shaped seedlings.

(B) Conventional technology Conventionally, seedling placing portions each having a width substantially equal to the width of the mat-like seedling are formed by separating a plurality of partition ribs between both side frame ribs of the bottom plate having a curved gently inclined surface at the top, and Along the seedling feeding direction from the gently inclined surface of each seedling placing part to the lower plant, a supporting rib having a ridge formed on the top surface and a supporting rib having a flat top surface are provided at predetermined intervals. It is already known that the rice transplanter's seedling stand, which has been provided with a plurality of rows.

(C) Problems to be solved by the invention However, when the seedling mounting table of the known rice transplanter has a certain inclination, a well-rooted seedbed is difficult to slip, and conversely a poorly-rooted seedbed is slippery. Easy, also, there is a difference in slip resistance of other artificial nursery beds made of foam or other material, slippery nursery beds, buckling or compression occurs in the steep slope,
Non-slip products have problems such as unsatisfactory supply,
In particular, in order to stably hold the placement state of mat-like seedlings,
When the curved gently sloping surface is formed on the upper part of the seedling placing part, there is a problem that the above-mentioned inconvenience becomes more prominent in combination with the slidable movement of the mat-shaped seedling.

Therefore, in order to solve the above problems, a large number of rolls or sawtooth-shaped resistors are provided on the bottom surface of the seedling stand so that they can appear and disappear,
Some proposals have been made to change the sliding condition of mat-shaped seedlings by adjusting the appearance of the mat-like seedlings.However, these have a complicated structure and the adjustment operation is complicated, and the weight of the seedling stand increases, so running There was a trade-off defect that the seedling table could not be smoothly reciprocated laterally under the influence of the body swinging inside.

In view of the above situation, the present invention was devised in order to eliminate the conventional drawbacks by focusing on the sliding motion of the mat-shaped seedling on the gently inclined surface formed in the curved shape on the upper part of the seedling placing part. , The purpose of this is to attach a slip tape to the apex located on the gently sloping surface of the supporting ribs provided on the seedling placing part for the seedbed that is difficult to slip even though it has an extremely simple structure. When planting a seedling of a slippery nursery from the above, by peeling off the slip tape, it is possible to properly respond to the difficulty of slipping on the gently sloping surface of the nursery, and the side portions of the side frame ribs or partition ribs. An object of the present invention is to provide a seedling placing table for a rice transplanter that complements the sliding state of a mat-like seedling that slides down while rubbing and can supply a smooth seedling regardless of the placement position of the seedling.

(D) Means for solving the problem In order to solve the problem, the technical means adopted by the present invention is that the space between the both side frame ribs 13, 13 of the bottom plate having the curved gently sloping surface 16a is formed on the upper part. , A plurality of partition ribs 15 are formed to form seedling placing portions 16 each having a width substantially equal to the width of the mat-like seedling, and the top surface is provided along the seedling feeding direction from the gently inclined surface 16a to the lower planting body 9. In a seedling placing table 8 of a rice transplanter in which a plurality of supporting ribs 17 'each having a ridge and a supporting rib 17 having a flat top surface are provided at a predetermined interval, the seedling placing portion 16 is gently inclined. On the top surface of the support rib 17 located on the surface 16a, a slip tape 20 having a small slip resistance is removably attached, and
On the top surfaces of the supporting ribs 17 adjacent to the side portions of the side frame ribs 13 or the partition ribs 15, a sliding tape 20 'that is longer than the lower edge of the sliding tape 20 attached to another supporting rib 17 is provided. It is characterized by being attached.

(E) Action Therefore, according to the present invention, a slip tape attached to the top surface of the supporting ribs on a gently sloping surface where the sliding motion of the mat-shaped seedlings tends to vary, regardless of the difficulty of sliding down the mat-shaped seedlings. The seedlings can be smoothly supplied to the plant through the pad, and even for mat-shaped seedlings with a large slip resistance that slide off while rubbing the side portions of the side frame ribs or partition ribs. The condition can be sufficiently complemented and the seedlings can be accurately delivered without delay in supply regardless of the placement position of the seedlings.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings. 1 is a mission case mounted on the front part of a body 2, and an engine 3 is mounted on an engine frame protruding from the front part, A planting device 6 is mounted on the rear part of the machine body 2 through a top link 4 and a pair of left and right lower links 5 so as to be able to move up and down. The planting device 6 reciprocates in a transmission case 7 in a lateral direction. It is composed of a seedling stand 8, a large number of planting bodies 9, a float 10 and the like, the input shaft of which is the mission case 1
It is driven by the PTO shaft via the intermediate shafts 11, 12.

The seedling mounting table 8 is inclined toward the top link 4, and as shown in FIG. 3, a curved gently inclined surface 16a is formed from the middle to the upper side in a side view. Partition ribs 15 are provided on the bottom plate between the side frame ribs 13 of the plurality of seedling placing portions 16 at intervals substantially equal to the width of the mat-like seedlings.
In order to increase the rigidity of the seedling table 8 made of a thin plate, and to obtain a frictional resistance suitable for supporting and delivering a seedbed relatively slippery such as a seedbed with poor rooting,
At the bottom of each seedling placing portion 16, a supporting rib 17 'having a protrusion 18 formed on the top surface and a supporting rib 17 having a flat top surface are alternately provided at a predetermined interval, and the mat-shaped seedling is formed. When replenishing
A ridge 18 formed on the top surface of the support rib 17 'receives the scraper.

Further, among the plurality of supporting ribs 17, the sliding tape 20 made of ultra-high molecular weight polyethylene or the like is provided on the top surface of the supporting rib 17 provided independently between the partition ribs 15 and 15 on the gently sloping surface 16.
While being affixed with an adhesive located at a, the supporting ribs 17 other than the above, that is, the top surface of the supporting ribs 17 provided adjacent to the side portions of the side frame ribs 13 or the partition ribs 15, A sliding tape 20 ', which is longer than the lower edge of the sliding tape 20 attached to the top surface of the above-mentioned independent supporting rib 17, is attached.

In the drawing, 22 is a seedling retaining rod, 23 is a lower supporting member thereof, 25 is an upper supporting member, 26 is a base supporting rod, 27 is an upper locking rod, and 28 is an upper part of the bottom plate of the seedling mounting table 8. A long hole, 29, is formed near the stand, and is a stand of the planting device 6.

Since the present invention is configured as described above, when planting work is carried out by the planting device 6 of the traveling rice transplanter, the planting bodies 9 ... The plants are scraped off one by one and planted in the field one after another. Then, when the seedling placing table 8 reaches the laterally moving end portion, the delivery belts 21 rotate so that the seedlings are fed out until the lower end thereof comes into contact with the apron.

Here, when the seedbed to be fed out is a slippery one such as a mat-shaped seedling with good rooting or an artificial mat, the sliding tape 20 attached to the gently sloping surface 16a reduces the friction resistance at the time of sliding. The seedlings can be delivered smoothly.
Also, the seedlings placed adjacent to the side portions of the side frame ribs 13 or the partition ribs 15 have an increased frictional resistance caused by rubbing against the side portions when sliding off, and the sliding tape 20 extending downward. ′ Will be supplemented as much as possible, and regardless of the placement position of the mat-shaped seedlings, it is possible to suppress the slide-down delay and to supply seedlings smoothly, and to continue smooth seedling planting work. You can

Further, if the nursery is slippery, peel off the slip tape 20 entirely or cut off by cutting off a part of the lower part to obtain an appropriate frictional force, and in any case, it is possible to easily adjust the sliding condition, The seed bed can be delivered in an appropriate amount without being excessively compressed or buckled.

(G) Effect of the invention In short, the present invention requires the curved gentle sloped surface 16a at the top.
Between the side frame ribs 13, 13 formed on the bottom plate, a plurality of partition ribs 15 are provided to form seedling placement portions 16 each having a width substantially equal to the width of the mat-shaped seedling, and the planting is performed downward from the gently sloping surface 16a. A seedling of a rice transplanter in which a plurality of support ribs 17 'having protrusions on the top surface and a plurality of support ribs 17 having a flat top surface are provided at predetermined intervals along the seedling feeding direction reaching the body 9. In the mounting table 8, slip tapes 20 having a small slip resistance are detachably attached to the top surfaces of the supporting ribs 17 located on the gently inclined surface 16a of the seedling mounting portion 16, and the side frame ribs 13 or the partition Rib 15
On the top surface of the support rib 17 adjacent to the side of the
The sliding tape 20 ', which is longer than the lower edge of the sliding tape 20 attached to 17, is attached, so that the mat-shaped seedlings can be easily slid on the gently sloping surface, which is likely to vary even though it has an extremely simple structure. For slip-resistant seed beds, a slip tape is attached to the top of the support ribs provided on the seedling placing section on the gently inclined surface, and when seedlings with slippery seed beds are to be planted from this state, By peeling off the slipping tape, it is possible to appropriately deal with the difficulty of slipping on the gently inclined surface of the nursery.

Even for seedlings placed adjacent to the side of the side frame ribs or partition ribs, the increase in frictional resistance caused by rubbing against the side when sliding down can be done with a sliding tape extending downward. This can be complemented as much as possible, and regardless of the placement position of the mat-like seedlings, the delay of seedling supply due to variations in slippage can be suppressed and the seedlings can be sent out smoothly.

Since no special structure is required to adjust the sliding condition of the mat-shaped seedlings, the weight of the seedling mounting base does not increase, and there is no need for a seedling mounting base that is generated when the machine is vibrated during running. It is possible to suppress the shaking, and it is possible to maintain a smooth lateral reciprocating motion of the seedling mounting table.

Since cheap slip tape is simply attached detachably, cost can be reduced and the optimum matte seedling slide condition can be easily set for each type of existing rice transplanters. can do.

And so on, which have extremely useful practical effects.
