Description

[Detailed description of the invention] The present invention consists of a seedling stand with a plurality of partitions for storing seedlings horizontally side by side and a plurality of claws. The purpose of this rice transplanting machine is to use a conventional rice transplanting machine that is configured to enable dense planting with row spacing narrower than the standard planting row spacing. The present invention aims to facilitate the work of loading seedlings onto the seedling rack without significantly changing the overall specifications of the seedling rack, and to eliminate the inconveniences that occur at the end of the lateral movement direction of the seedling rack, i.e., at the end of the lateral movement process. When taking out seedlings, the group of seedlings cantilevered by these seedlings will shift toward the seedling take-out port side, causing disturbances in the storage posture, which can avoid problems such as missing plants. The point is to try to fake it.

Therefore, rice cultivation in our country has traditionally placed emphasis on quality, in other words, the production of high-quality rice, as well as quantity, and rice farming equipment has been designed with this in mind.

Specifically, when growing rice, a method of rough planting is used.

This is intended to promote good growth of rice by increasing the distance between seedlings planted on the rice field from around 26 cm to around 30 cm to improve sunlight and ventilation for the seedlings.

Therefore, even if we consider rice transplanters, most of them that are currently widely used are, for example,
As typified by the one described in Publication No. 16839, the spacing between the planting claws is about 30 cm, the width of one seedling placing part of the seedling stand is also about 30 cm, and the width of each seedling placing part is about 30 cm. For a long time, a machine specification has been established in which a single planting claw is provided to move the seedling stand back and forth by 30 cm on each side.

In other words, at present, such aircraft specifications are recognized by those skilled in the art as basic technology that has already been completed.

However, recently, new demands have arisen due to the fact that rice transplanters have begun to spread overseas as well as the production of feed rice tends to increase even in Japan. There is.

In other words, rice cultivation overseas generally tends to place more emphasis on quantity than quality, and domestic feed rice also places priority on quantity over quality. In other words, through a method called dense planting, sunlight and ventilation,
Alternatively, it has been adopted to greatly reduce the spacing between seedlings and increase the yield, even if it means sacrificing some efficiency in management work.

The inventor of this invention began development to meet this new demand,
Initially, based on the conventional fixed idea, the seedling resting table was divided into the same number of rows according to the number of rows required for planting, and one planting claw was provided for each unit seedling resting part. As a result of devising a method and conducting various studies, we found that in this case, the conventionally used and widely popular seeding and seedling raising equipment could not be used, and a new equipment would have to be developed, and furthermore, planting would be an arduous task. Near the end of the horizontal movement of the seedling tray, the side of the seedlings on the dairy seedling tray where the seedlings have already been scraped slides down, causing the leading edge of the seedling to slope and causing plant breakage, which is not compatible with the purpose of dense planting. I was faced with the new problem of causing undesirable results, and only then did I realize that as long as I stuck to the conventional fixed ideas, I would never be able to devise a means to solve the original problem. Taking this opportunity, as a result of various ideas, we were able to completely break away from this conventional fixed idea and develop an extremely ideal and novel densely planted rice transplanter that did not exist before, and we would like to offer it to you.

First, an embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a riding rice transplanter, in which a transmission case 2 directly connected to an engine 1 is connected to a chain case 4 of a pair of left and right running wheels 3 arranged at one place in the front and back direction when viewed from the side. A grounding float 5 is provided on the lower side of the engine 1 so as to be able to move up and down by driving around a certain horizontal axis, and a grounding float 5 is provided on the lower side of the engine 1 to stably support the aircraft body with the pair of left and right drive wheels 3. For planting 8 rows, a frame 6 extending rearward from 2 is equipped with a device A, which is planted at a row spacing of % of the standard planting row spacing. It is suspended elastically.

The planting device A is stolen as shown in FIG. 2 as follows.

That is, the frame 9 extending forward and upward from the horizontally long transmission case 8 and the plantings extending rearward from four locations in the longitudinal direction of the horizontally long transmission case 8, which extend from the case 10, correspond to standard planting rows. A forward-slanting seedling stand 11 having a plurality of partitioned seedling stand parts 11A capable of horizontally storing mat-like seedlings having widths such as The rear part of the case 10 has two claws 12 for taking out mat-like seedlings and planting them at six bisected positions in the width direction of each unit seedling resting part 11A of the seedling resting stand 11. The attached mechanism 13 is provided, and
Inside the horizontally elongated transmission case 8, there is provided a mechanism 14 that reciprocates the seedling stand 11 in the lateral direction over the distance between the adjacent claws 12 and 12 of the seedling planting mechanism 13.

The seedling planting mechanism 13 is used as follows.

That is, the planting is carried out using the crank arm 1 which is pivotally supported by the case 10.
5, the free end of which is attached to the claw 12 is pivotally connected to the middle part of the arm 16, and the rear end of the arm 16 is connected to the driving rotation shaft of the crank arm 15. It is pivotally connected to the free end of an arm 17 that is swingable around an axis parallel to the core, so that by the combined movement of the drive rotational movement of the crank arm 15 and the swinging movement of the swinging arm 17. During the planting, the claw 12 of the arm 16 is used to reciprocate and circulate between the seedling outlet 11a at the lower end of the seedling stand 11 and the mud surface.

The mechanism 14 is intercepted as follows.

That is, in the horizontally elongated transmission case 8, a feed shaft 18 connected to the seedling stand 11 and a human power shaft 19 are interlocked with gears.7. =9 shaft 20 is installed, and the driven member 21 engaged with the endless spiral groove 20a of the screw shaft 20 is fixed to the feed shaft 18, so that the screw shaft 20 and the driven member 21 By the lateral movement of the feed shaft 18 in conjunction with the relative rotation between the seedling tray 11 and the seedling planting mechanism 13, the seedling platform 11 is intercepted and reciprocated in the lateral direction over a width of 12 degrees between adjacent claws in the mechanism 13. There is.

The above-mentioned standard planting row spacing is set to 30 cm, and the spacing between adjacent claws 12 and 12 in the seedling planting mechanism 13 is set to 15 cm.

In summary, the rice transplanter according to the present invention includes a seedling tray 11 having a plurality of partitioned seedling loading portions 11A capable of storing mat-shaped seedlings having a width corresponding to the width between standard planting rows side by side in the horizontal direction; The seedling planting mechanism 13 is provided with a plurality of claws 12 for taking out and planting mat-like seedlings at equal positions in the width direction of each unit seedling placement part 11A of the stand 11, and The platform 11 is used for planting the seedlings, and the mechanism 13 is used for planting the seedlings.
It is characterized by being provided with a mechanism 14 that reciprocates the adjacent claws in the lateral direction over a width of 12 degrees.

That is, in order to enable dense planting with row spacing narrower than the standard planting row spacing, the mat-shaped seedlings of standard width stored in each unit seedling placement portion 11A of the seedling placement platform 11 are placed next to each other. By intercepting the seedlings to take them out with multiple claws arranged at equal positions in the width direction, this single mat-shaped seedling can be used as mat-shaped seedlings in multiple rows, making it a more widely used seedling raising method than before. There is no need to make any changes to the box sowing seedling raising device or the management device, or to the seedling raising work process or content, etc., in short, to the entire seedling raising operation, and the conventional seedling raising method can be used as is. The loading work can be facilitated.6Moreover, even when taking out the final seedlings in the horizontal movement process of the seedling table 11, the mat-shaped seedlings can be supported at multiple positions in the width direction of the mat. Disturbances in the storage posture of seedlings, such as the seedlings shifting and tilting toward the seedling take-out port, do not occur or can be minimized, thereby eliminating the problem of missing plants caused by such disturbances in the posture of storing seedlings. The planting of this tree has allowed us to avoid problems.

Furthermore, the specifications of the machine are to shorten the length of the transverse feed of the seedling stand, that is, to shorten the length of the helical shaft for transverse feed.
The desired requirements can be met by making three changes: increasing the number of seedling extraction ports and increasing the number of seedling planting claws, so there is no need to make major changes to the machine specifications, reducing manufacturing processing, costs, and use. We have now been able to provide an extremely advantageous product in terms of convenience (it can be handled in the same way as conventional machines), etc.
