Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for releasing a seedling stopper in a rice transplanter such as a riding-type rice transplanter.

[Problems to be solved by the prior art and the invention] In general, with this seed rice transplanter, when planting work at the edge of a ridge, for example, one stroke is shorter than the final planting process at the furthest edge. In the previous planting process, adjust the planting rows by reducing the number of planting rows, etc., and in the next planting process, perform the planting work in all the planting rows. During the process, we make sure not to trample on already planted seedlings or double-plant them. Therefore, a seedling stopper is installed on the seedling stand in the seedling planting section in order to restrict the feeding of the seedlings placed on the seedling stand. After the planting process is completed, the operator must manually release the seedling stopper each time before starting the next planting process, and this process is extremely complicated and troublesome, and is often forgotten. This has become a problem as the plants may end up being planted in the air.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a release device for a seedling stopper in a rice transplanter that can eliminate these drawbacks. In a rice transplanter, in which a seedling planting section equipped with a seedling platform having an inclined seedling loading surface is provided on a traveling machine so as to be able to be raised and lowered, the planted seedlings placed on the seedling loading surface are vertically fed to the seedling loading platform. A seedling dispensing body for dispensing the seedlings in a certain direction and a seedling stopper capable of regulating the dispensing of the planted seedlings placed on the seedling mounting surface are provided, and the lifting mechanism for the seedling planting section is provided with a mechanism for raising the seedling planting section. A raising operation mechanism is provided which operates in conjunction with the operation, and the raising operation mechanism is connected in conjunction with the seedling stopper, so that the seedling stopper is automatically changed from the feeding restriction position to the releasing position in conjunction with the raising of the seedling planting section. It is characterized by being constructed in such a way that it can be transformed into.

With this configuration, the present invention makes it possible to release the restriction on feeding out the seedling stopper in conjunction with the rise of the seedling planting section, thereby preventing forgetting to release the seedling stopper.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a traveling body of a riding type rice transplanter, and a seedling planting section 3 is provided at the rear of the traveling body 1 via an elevating link mechanism 2 so as to be vertically movable. 4 is a seedling mounting stand with an inclined seedling mounting surface;
5 is a planting claw, 6 is a float, 7 is a seedling receiver provided below the seedling platform 4, and 8 is a feeder for vertically feeding out the planted seedlings 15 placed on the seedling platform 4. These are all configured in the conventional manner.

Reference numeral 9 denotes a plate fixed to the partition protrusion 4a of the seedling stand 4 with bolts 9b, and a substantially U-shaped bracket 9a formed at the tip of the plate 9 has an operating shaft for a seedling stopper 11, which will be described later. 10 is supported in the left and right direction, and the operating shaft 10 has a stopper pawl 11a disposed at a position where seedling feeding can be stopped and an operating plate 12 located within the bracket 9a, respectively. is fixed. One end of the actuating plate 12 is stopped on the side of the seedling stand 4, and the other end of a bullet 13 that operates beyond the fulcrum with the actuating shaft 10 as a fulcrum is locked. Further, a base end portion of an operating lever 14 extending along the partition protrusion 4a is pivotally connected to the operating plate 12. When the operating lever 14 is operated in the direction of the arrow X (toward the upper end of the seedling stand 4) as shown in FIG.
The seedling stopper 11 rotates with the action of moving over the fulcrum of the bullet 13 until it comes into contact with the rear lower edge of the seedling stopper 11 and is restricted from swinging. The seedlings 15 are placed in a feed-out regulating position (the solid line state in Fig. 2) and bite into the planted seedlings 15 placed on the table.
It is now possible to regulate the feeding and lowering of the Conversely, when the operating lever 14 is operated in the direction of the arrow Y (toward the lower end of the seedling stand 4), the operating plate 12 moves to the bracket 9a.
The seedling stopper 11 rotates with the action of moving over the fulcrum of the bullet 13 until it comes into contact with the lower front edge of the seedling and the rotation is restricted, and as a result, the seedling stopper 11 comes out of the planted seedling 15 and assumes the release position. (Virtual line state in FIG. 2), the above-mentioned downward restriction on the planted seedlings 15 is released.

Reference numeral 16 denotes a bracket protruding from the rear surface of the seedling stand 4, and an operating body 17 is integrally fixed to a pivot shaft 16a rotatably provided on the bracket 16 by a pin 18. A base end portion of a swinging arm 19 is integrally fixed to a boss portion 17a implanted in the actuating body 17. This swinging arm 19 is the seedling stand 4
The insertion hole 1 penetrates through the elongated hole 4b formed in the partition protrusion 4a, and the insertion hole 1 is formed in the tip of the swinging arm 19.
The tip of the operating lever 14 is slidably inserted into 9a. On the other hand, the arm body 1 protrudes from the operating body 17
One end of the inner wire 20 is connected to 7b, and the other end of the inner wire 20 is fixed to the upper link 2a of the elevating link mechanism 2 while the outer receiver 20a is fixed to the body frame 1a of the traveling body 1. I'm being forced to do it. Then, in conjunction with extending the hydraulic cylinder 25 and raising the seedling planting section 3, the inner wire 20 is pulled.
This allows the swinging arm 19 to move in the direction of the arrow Y together with the operating lever 14 against the tensioner 21 interposed between the arm body 17b and the bracket 21a protruding from the rear surface of the seedling stand 4. However, Atsupa Link 2
At the stage when a approaches the upward movement position, the projectile 13 crosses over the fulcrum, and the seedling stopper 11 automatically changes from the feeding-out regulating position to the releasing position, thereby allowing the main An inventive lifting actuation mechanism is constructed. Here, 14a is an engagement with which the swing arm 19 engages to push out the operating lever 14 when the swing arm 19 swings in the direction of the arrow Y as the seedling planting section 3 rises. pin, 22 is a seedling presser, 23 is a guide for the operating lever 14, 24 is a support shaft 16a
It is a guide body for.

In the embodiment of the present invention configured as described above, normal seedling planting work is performed with the seedling stopper 11 in the released position by operating the operation lever 14 in the direction of the arrow Y. When starting the planting process one step before the final planting process, it is necessary to adjust the rows to reduce the number of planting rows. In such a case, pull the operating lever 14 corresponding to the planting row to be reduced in the direction of the arrow If the seedling stopper 11 is in this feeding regulating position,
The machine bites into the planted seedlings 15 and reliably controls the feeding, and there is no problem such as the planted seedlings 15 naturally sliding down the inclined seedling platform 4 due to vibration of the machine, etc.
Can perform reliable row alignment work. When the planting work in this process is completed and the planting work is to be carried out using all the planting rows in the next process, in this invention, there is no need for the operator to release the seedling stopper 11 one by one as in the past. Instead, the seedling stopper 11 is automatically released by the necessary upward movement of the seedling planting section 3 when the machine rotates.

That is, in the present invention, by moving the uplink 2a upward to raise the seedling planting section 3, the inner wire 20 is pulled, which causes the swinging arm 19 to swing and move the operating lever 14 in the direction of the arrow. This results in forced movement in the Y direction. When the seedling planting section 3 is raised, the seedling stopper 11 is automatically transformed from the feeding restriction posture to the release posture under the action of the bullet 13 to move over the fulcrum, and is held in this posture. Therefore, after the machine has rotated, the seedling planting section 3 can be lowered again to the planting position to perform planting work using all the planting rows.

As described above, in the present invention, the feeding of the planted seedlings 15 can be reliably stopped by the seedling stopper 11 in the feeding regulating position, but the release operation of the seedling stopper 11 is as follows. This is automatically done by the upward movement of the seedling planting part 3 that is necessary when the machine rotates, and therefore, the release of the seedling stopper 11, which is extremely troublesome and troublesome, has to be done manually by the operator each time as in the past. In addition to eliminating the need for any work,
There is almost no need to worry about empty planting due to forgetting to release the button.
This can significantly improve work efficiency.

Further, since the swinging arm 19 is designed to engage the operating lever 14 only in the direction of the arrow Y, that is, in the direction that changes the seedling stopper 11 to the release position side, the swinging arm 19 engages with the operating lever 14 only in the direction of the arrow Y, that is, in the direction that changes the seedling stopper 11 to the release position side. It is convenient because the manual transformation work between the feeding-out restriction posture and the release posture (No. 11) can be carried out freely as needed.

It should be noted that the present invention is, of course, not limited to the above-mentioned embodiment, and is configured such that the automatic transformation operation of the seedling stopper to the release position is performed in conjunction with the rise of the seedling planting section. As long as it is done, the means used do not matter.

[Operation and Effect] In short, the present invention is constructed as described above, and the regulation of seedling feeding of the planting rows necessary for row alignment can be achieved by transforming a dedicated seedling stopper into a feeding regulating position. As a result, the row alignment work can be performed reliably, and there is no problem such as the planted seedlings whose feeding is regulated naturally sliding down the inclined seedling mounting surface due to vibration of the machine, etc., and the row alignment work can be performed reliably. In addition, this seedling stopper is automatically linked to the raising operation of the seedling planting section, which is necessary when the machine rotates to move on to the next planting process after the planting work in the row-combined planting process is completed. This allows the robot to change from the feeding restriction posture to the release posture, which eliminates the need for the troublesome manual release work that was previously required, and allows the final stage of planting in all planting rows to be carried out immediately after the machine has rotated. This not only significantly improves work efficiency, but also almost eliminates empty planting due to forgetting to release the button.
