Description

[Detailed explanation of the invention] When constructing a rice transplanter that is a riding type instead of a walking type that is commonly used, operator fatigue is greatly reduced and work efficiency is greatly improved. However, this invention relates to a seedling stand for such a riding rice transplanter.

In other words, this idea was developed to reduce the burden of transferring seedlings onto the seedling stand of the rice transplanter as much as possible in a riding rice transplanter that is used for multi-row planting. We would like to provide a new seedling mounting stand for a riding rice transplanter that is configured so that multiple seedling mats can be placed in series without causing any problems. It is something to do.

Regarding the illustrated embodiment, the structure of the seedling stand according to this invention will be explained. First, the illustrated riding rice transplanter is:
As shown in Fig. 1, a support frame F made of pipe material is attached to the rear of a riding tractor-type machine T by an upper top link 1 and a lower pair of left and right lower links 2. are connected so that they can be raised and lowered freely,
The rice-transplanting device P
The rice transplanting device P can be connected to the rice transplanting device P by using this machine T.
The machine is configured to drive rice in a flooded field while towing it to perform rice planting work. As usual, the rice transplanting device P is configured to include a seedling platform 6, a planting arm 7, a float 8, etc., but the seedling platform 6 in this rice transplanting device P is particularly equipped with a seedling platform 6 as shown in the figure. It is inclined in a straight line with a backward downward shape, and in particular, there are multiple sheets (two in the case shown).
The length is such that it is possible to place several seedling pine trees in series along the inclination direction.

A seedling pine holding device as described below is provided on the seedling mounting table 6, which has a length that allows two seedling pine mats to be placed in series in this manner.
That is, as shown in FIGS. 1 and 3, this seedling pine presser has two sets of seedling pine pressers 23 vertically arranged in series: a lower seedling pine presser 23 and an upper seedling pine presser 23'. . 24, 24', and at the inner corner of each support frame 24, 24', the support rod 24,
A pair of horizontal bars 25, 25' are fixed to 24' and run along the width direction of the seedling stand 6, and both free ends are appropriately curved and fixed to the horizontal bars 25, 25' near both ends. It consists of a pair of presser rods 26, 26'. And each seedling pine presser 23,2
3' also holds the seedling stand 6 with its presser rods 26, 26'.
It is configured to hold down the seedlings on top,
The upper seedling pine presser 23' is such that when two seedling pine are placed in series on the seedling platform 6 or each seedling loading section 6a, the presser rod 26' of the seedling pine presser 23' is in the upper position. It is placed in such a position that it can hold down the lower end of the seedling pine on the side.

Furthermore, as shown in FIG. 3, by providing the presser rods 26, 26' of each set of seedling pine pressers 23, 23' with their positions shifted from each other in the width direction of the seedling platform, the seedling pine pressers 23, 23' of each group , 23' are adapted to press the seedling pine at different positions when viewed in the width direction of the seedling table, and both seedling pine pressers 23, 23' or their presser rods 26, 26' are moved in the direction of the slope of the seedling table. They are arranged so that they overlap in some areas. In FIG. 3, 44A and 44B are a large number of isolated convex portions arranged in a staggered manner on the upper surface of the seedling stand 6, and the upper convex portion 44A is the lower convex portion 4.
The cross section is larger than that of 4B, so that when two seedling mats are placed in series on the seedling platform 6, the slip resistance of the upper seedling mat is greater.

In addition, the support frame F described above has the pipe material further extending rearward from both ends of the lower end of the front end rising frame part 3, and the pipe material is extended diagonally rearward and upward from the front position of the planting arm 7 when viewed from the side. The rear end is provided with another rising frame portion 9 in the shape of a slanted gate. And the support frame F
The following riding section S for an auxiliary worker is provided by using the above-mentioned rising frame section 9 constituting the rear end section. That is, the above-mentioned rising frame portion 9
A support pipe 10 is provided to span between the pipe materials 9a on both sides, and a pair of support pipes 11 on both sides are fixedly supported at the lower ends of the pipe materials 9a on both sides. A framed passenger frame 13 is provided, and the passenger frame 13 includes a passenger seat 14 facing the rear descending seedling stand 6, and a deck 16 supported so as to be movable up and down around a fulcrum shaft 15. A deck 16 is provided at the lower front of the passenger seat 14, and a guardrail 17 is provided integrally with the passenger frame 13 at the front end of the frame 13, with the upper end thereof being close to the seedling stand 6 direction. A riding section S is constructed by supporting a gate-shaped guardrail 17 that is inclined in the direction of the vehicle. In the illustrated case, the riding section S has a pair of left and right tails that are connected and supported to the rising frame section 9 by a parallel link device 20 that includes one upper top link 18 and a lower left and right pair of lower links 19. The tail wheel 21 is supported from below by a wheel 21, and the tail wheel 21 is moved up and down via a parallel linkage 20 by a manual hydraulic jack 22 whose cylinder end is pivotally supported on the upright frame portion 9. It is said that the vertical position can be adjusted according to the depth of the tiller, etc.

The passenger tractor type machine T is equipped with an engine 27 at the front of the machine body, like a normal passenger tractor, and the power of this engine 27 is transmitted to the clutch housing 28 and transmission, which respectively constitute a part of the machine body. The power is transmitted to the rear of the aircraft through the case 29 and drives the left and right rear wheels 30 to cause the aircraft to travel, as well as to rotationally drive the PTO shaft 31 extending to the rear of the aircraft. Further, a worker seated on a passenger seat 32 installed on the upper surface of the rear part of the aircraft rotates the front wheels 34 using a control handle 33 to steer the aircraft. The driving of the rice transplanting device P, that is, the horizontal reciprocating drive of the seedling platform 6 and the rotating drive of the planting arm 7, is achieved by providing a transmission shaft 35 that transmits power from the PTO shaft 31 of this machine T in the direction of the rice transplanting device P. This is done by power transmission from the T side of the machine.

In Fig. 1, 36 is a hydraulic lift arm provided on the machine T, 37 is a tie rod that connects this hydraulic lift arm 36 to the lower link 2, and the lifting operation of the lift arm 36 raises the rice transplanting device P together with the support frame F. 38 is a pair of left and right auxiliary springs stretched between the machine T and the support frame F to support the support frame F by pulling it upward; 39 is the rising frame portion of the support frame F; A pair of left and right auxiliary springs stretched between 3 and the rice transplanting device P support the rice transplanting device P by pulling it upwards, and 40 is a preliminary seedling mounting table supported by the seedling mounting table 6. In FIG. 2, 16a is a large number of through holes provided in the deck 16, and 41 and 42 are brackets fixed to the passenger frame 13 and the pipe 16b at the rear end of the deck 16, respectively. In addition, the fulcrum shaft 15 is inserted therethrough. Reference numeral 43 denotes a horizontal pipe provided on the passenger frame 13, which receives the deck 16 from below and maintains the horizontal posture of the deck 16 with downward rotation.

Rice-transplanting work using the illustrated riding rice transplanter is carried out in the usual manner by the rice-transplanting device P while the rice-transplanting device P is towed together with the support frame F by the machine T as described above, and the machine is traveling. In Case of,
The rice transplanting device P is provided with a seedling loading stand 6 which is tilted in a straight line in a backward downward direction and is capable of placing a plurality of seedling mats in series; The configuration in which the riding part S for the auxiliary worker is installed at the rear of the rice transplanting device P so as to face each other, together with the structure, increases the burden of transferring seedlings from the preliminary seedling platform 40 to the seedling platform 6. It is expected to be reduced significantly. That is, during the rice planting work, an auxiliary worker sits on the passenger seat S and can inspect the planting state using the rice transplanting device P and perform the above-mentioned seedling succession work, and then sit on the passenger seat 32 of the machine T. The worker only needs to concentrate on operating the machine T, but when looking at the seedling transfer work for the auxiliary worker, first the seedling loading table 6 loads two seedling mats in series. Since the structure is long enough to allow seedlings to be placed, the frequency of seedling succession work is extremely reduced. There is no need to carry out seedling succession. In addition, when carrying out this seedling succession work, the riding part S on which the auxiliary worker rides is located opposite the seedling platform 6, and the seedling platform 6 is linear and does not support the seedlings. Since the upper end side of the stand 6 is not separated from the riding part S, this seedling splicing work can be performed very easily.

Regarding the seedling stand 6 itself, the seedling stand 6 is equipped with a seedling pine presser 23' that presses the lower end of the upper seedling pine out of the two seedling pine lines arranged in series. When two seedling mats are placed in series in each of the seedling mounting sections 6a, the upper seedling mats, which tend to curl up on the lower end side, are prevented from turning over. In addition, two seedling pine pressers 23, 2 are placed in series vertically.
Since the seedling pine holding device equipped with 3' holds down almost the entire lower side seedling pine, seedling collapse of the upper side seedling pine due to being pushed by the upper side seedling pine does not occur. Furthermore, since the seedling pine pressers 23 and 23' arranged vertically in series are arranged so as to press the seedling pine at different positions when viewed in the width direction of the seedling platform, the seedling pine pressers 23 and 23' are arranged so as to press the seedling pine at different positions when viewed in the width direction of the seedling platform. The seedling pine is less likely to be damaged as would be the case when the pine is held down, and the seedling pine pressers 23 and 23', which are arranged vertically in series, are arranged so as to partially overlap when viewed in the direction of the inclination of the seedling table. When the end of the seedling pine presser 23 on the lower side of the slope enters, it is pressed by the seedling pine presser 23' on the upper side of the slope and is guided so as not to turn over. It will fall under 23.

In this way, the seedling stand of the riding rice transplanter of this invention has a length along the slope direction of the seedling stand that is set to a length that allows multiple seedling mats to be placed in series. When a plurality of seedling pine pressers 23, 23' are arranged vertically in series from the lower end of the direction upward, and a plurality of seedling pine pressers are placed in series, the uppermost seedling pine presser 23' is placed in the uppermost row. The seedling pine pressers 23, 23' of each set press down the seedling pine at different positions when viewed in the width direction of the seedling table, and hold down the seedling pine up to the lower end of the seedling pine, and simultaneously press the seedling pine of two sets of vertically adjacent seedlings. It is characterized by the fact that the pine holders 23, 23' are arranged so as to partially overlap when viewed in the direction of inclination of the seedling table, so that a plurality of seedling pine can be placed in series. As a result, the burden of transferring seedlings onto the seedling table is greatly reduced, but no problem will occur even if a plurality of seedling mats are placed in series in this way.

In other words, when multiple seedling mats are placed in series, the lower ends of the upper seedling mats tend to curl up, but the seedling mounting stand of this invention has multiple sets of seedling mat holders arranged vertically in series, and the uppermost row of seedling mats is Seedling pine presser 2
3' is arranged so as to press down to the lower end of the seedling pine placed on the top tier, so that the lower end of the seedling pine does not turn over as described above, and Since multiple sets of seedling pine pressers are arranged vertically in series from the lower end of the seedling table in the direction of the slope upwards, when multiple seedling pine are placed in series, they are not pressed by the upper seedling pine. This prevents the seedlings from collapsing on the lower seedling pine. Furthermore, despite the provision of multiple sets of seedling pine pressers in series, each seedling pine presser is arranged so as to press the seedling pine at a different position in the width direction of the seedling platform, so the seedling pine presser is not enough to support the seedlings. Damage to the pine is reduced, and since the seedling pine holders arranged vertically in series are arranged with some overlap, the end of each seedling pine is held down by the upper seedling pine holder, while the lower seedling pine is held down. This means that it will go under the presser foot, and it will go in smoothly.
