Description

[Detailed description of the invention] This invention, for example, uses a seedling stand that moves back and forth from side to side to cut and hold one seedling with fixed claws and take it out, and forcefully plants it in the field with a movable claw or pushing arm. This is related to the planting device of the rice transplanter that will be used.

Conventional 11 For example, as shown in Japanese Utility Model Publication No. 54-10345, there was a technique of forming a forked push-in part on the arm part of a movable claw by casting or the like. Since the right and left middle portions of the proximal end thereof are formed approximately equally, and the arm portion is erected in a backwardly inclined manner, when the movable claw is plunged into a circular surface for planting, the base of the pushing portion is When the movable claw is raised from the circular surface while pushing the mud open with the end lower surface and the backwardly inclined lower surface of the arm part,
The proximal upper surface of the pushing part and the rearwardly inclined upper surface of the arm part kick up mud, and when the circular surface is hard during planting, the movable claw marks remain large, resulting in poor planting posture of the seedlings, and There were problems such as the equipment falling over and being submerged in water.

Therefore, by making the width of the forked tip side of the pushing part smaller, the width of the proximal end of the pushing part also becomes smaller, and it is possible to reduce the movable claw mark by this amount. By reducing the width of the forked tip, there was a problem that the forked tip would become clogged with mud and damage the planted seedlings.

The present invention addresses the above-mentioned conventional problems, and includes a fork-shaped movable claw at both ends, which is made by pasting together the middle of two symmetrical flat plates, and a structure for supporting the movable claw at one end of the movable claw. A two-pronged engaging part is formed at the other end, and a two-pronged pushing part for pushing out the planted seedlings is formed at the other end, and a movable claw is formed with the narrow base end of the pushing part that pushes the planting seedlings into a circular surface. The movable pawl intermediate arm portion is extended approximately parallel to the fixed pawl, and the arm portion is made to stand upright on the forked push-in portion. It is something.

However, in the present invention, the width of the pushing claw at the forked tip of the pushing part is made sufficiently wide, the width of the proximal end is made small, and the arm part is made to stand upright on the pushing part, so that planting can be done in a circular manner. The ground projected area of the pushing part and the arm part that plunge into the surface can be significantly reduced compared to the conventional one, and the planting marks formed by the pushing part and the arm part can be made smaller than before without clogging the pushing part with mud etc. The movable claws can be bent and welded to maintain the good planting posture of the seedlings even when the circular surface is hard, and to prevent the seedlings from being submerged and withered by tilting them. It can be produced easily and inexpensively, and compared to conventional casting, where changing the molding is not easy, it is possible to control the seedling pine properties of the planted seedlings and the circular properties (clay or sand, etc.) of the planted seedlings. It is also possible to easily modify the shape of the push-in portion to a corresponding shape.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Figure 1 is a general view of the rice transplanter. In the figure, 1 is the engine, 2 is the transmission case, and 3 is the planting mission case. The engine 1 and the cases 2 and 3 are integrated. The machine is connected in series to intercept the machine body, and paddy wheels 5 are installed on the side of the machine via a swing case 4.

A handle 6 extends above the rear end of the planting mission case 3, and a seedling stand 9 with a low front and rear height that is reciprocated from side to side via guide members 7 and 8 is attached to the case 3 and the handle 6.
At the same time, a planting claw 10 is installed to take out one seedling from the seedling stand 9, and the body is floated via a link 12 having a planting depth adjustment lever 11 and a guard member 13. It is supported by a shaped sliding body 14 and moved by the operation of a handle 6 by a walking worker, and the seedlings loaded on the seedling platform 9 are taken out by the planting claws 10, and the seedlings corresponding to - stocks are successively planted in the field. It is something that is taken over by someone else.

FIG. 2 is an enlarged view of the 3rd part of the planting mission case, and 15 in the figure is a fixed claw that is one of the planting claws 10 that cuts and takes out one planted seedling 16 from the seedling platform 9. A scraping claw 17 is a movable claw that seizes the other side of the planting claw 10 for forcibly pushing out the planted seedlings 16 held between the fixed claws 15 and planting them, and 18 is a movable claw and the fixed claw 15. A planting arm with a claw 17 installed at its tip; 19 a rotary arm that is pivotally supported on a planting claw drive shaft 20 and connected to the middle of the planting arm 18 via a shaft 21; and 22 a support integrally formed on the transmission case 3. Rotatably attached to the rod 23 is a swing arm connected to the rear end of the planting arm 18 via a shaft 24, and the fixing claw 15 is fixed to the planting arm 18 via bolts 25 and 25. A movable claw 17 is fixed to the tip of an operating shaft 26 that is slidably provided on the planting arm 18, and is operated via a hook piece 28 on one end of a push lever 27 that is swingably built into the planting arm 18. The inner end of the shaft 26 is connected, and the other end of the push lever 27 is brought into contact with the cam 29 of the shaft 21 fixed to the rotating arm 19, and the push lever 27 whose intermediate portion is pivoted to the shaft 30 is pushed. The spring 31 is energized, the movable claw 17 is reciprocated along the inside of the fixed claw 15, and the planted seedlings 16, which are cut and held by the fixed claw 15, are forcibly moved onto the field 32 by the push of the movable claw 17. They are stealing it and planting it on their own.

As shown in FIGS. 3 to 5, both ends of the movable claw 17 are bifurcated, and the movable claw 17 is made of two symmetrical flat plates formed by press working or the like and bonded together by spot welding or the like. At the same time, a forked engagement part 33 is formed at the other end via the arm part 34, and a forked push-in part 35 is formed on the other end side, and the arm part 34 is made to stand upright on this push-in part 35, and the arm part 34 is fixed as described above. The two-pronged engaging portion 33 is engaged with and welded to the tip of the planting arm 18 of the actuating shaft 26, and extends approximately parallel to the claw 15. At the same time, the pushing part 35 is slid and moved.
The planted seedling 16 is held between the fixed claws 15 by the lower surface of the tip side.
It is extruded and intercepted to plant seedlings 16 in the field.

Further, as shown in FIG. 4, the push-in portion 35 of the movable claw 17 has a width t on the proximal end side connected to the arm portion 34 that is relatively intermediate than the push-in claw width T on the distal end side adjacent to the fixed claw 15. Pincer (T>
t), and the proximal narrow width t of the pushing part 35 and the movable claw 1
The thickness of the two plates forming 7 is made equal, and when the planted seedlings 16 are planted in the field by the planting claws 10,
The seedlings 16 to be planted, held between the fixed claws 15, are reliably pushed out by the movable claws 17 and planted in the field with a good planting posture, without leaving a large trace of the claws in the field.

Note that 36 in the figure is a slit formed in the fixed claw 15.

The present invention is based on the above, and when seedlings are loaded on the seedling platform 9 and rice planting is carried out under the conditions shown in Fig. 1,
While reciprocating the seedling platform 9 from side to side, the rotary arm 19 is rotated at a constant speed via the drive shaft 20, and the swinging arm 22 is moved to move the planting arm 18 at an inconstant speed.
The planting claw 10 is moved in a planting cycle along this planting trajectory, the planting claw 10 takes out one seedling from the seedling stand 9, and the seedling is planted in the field. When the movement is performed continuously and the seedlings on the seedling platform 9 are sequentially planted, the planted seedlings 16 cut and held by the fixed claws 15 are inserted under the field surface 32 by the push of the movable claws 17 and planted. It's something to do.

FIG. 6 shows a modified structure of the above embodiment, in which the movable claw 17a is fixedly attached via a nut 37 to the threaded portion 26a of the operating shaft 26 whose tip protrudes from the outside of the planting arm 18. The movable claw 1
7a can be replaced.

Furthermore, FIGS. 7 to 8 show other modified structures of the previous embodiment, and in the previous embodiment, the forked part 35 of the movable claw 17 was made into a U-shape. In this configuration, the forked portion of the push-in portion 35b of the movable claw 17b is formed into a square shape.

Since this configuration also has the same functions and effects as those of the above-mentioned embodiment, the same parts are given the same numbers and detailed explanation thereof will be omitted.

As is clear from the above embodiments, the present invention has a fixed claw 15 that cuts and holds one planted seedling 16, and movable claws 17, 17a, 17b that push out the planted seedling 16 of the fixed claw 15. In the planting device of a rice transplanter equipped with a planting claw 10, the movable claw 17 has two symmetrical flat plates stuck together in the middle.
．． Both ends of 17a and 17b are opened in a bifurcated shape, and the movable claw 1
7. A two-pronged engaging part 33 is formed at one end of 17a, 17b to support it, and a two-pronged pushing part 35.35a, 35b for pushing out the planted seedling 16 is formed at the other end. For planting, the pushing part 35.35 is pushed into the rice field.
a, base end width t of 35b and movable claw 17.17a, 1
The thickness of the two plates forming the movable claws 17b are made equal, while the arm portion 34 between the movable claws 17.17a and 17b is extended substantially parallel to the fixed claw 15, The forked push-in portions 35.35a, 35b have their arm portions 34 upright, and the push-in portions 35.35a
, 35b, the width T of the pushing claw at the forked tip is made sufficiently wide, and the width t of the proximal end thereof is made small.
By making the arm part 34 stand upright on the push part 35.35b, the planting part 35.35a is pushed into the rice field.

35b and the arm portion 34 can be significantly reduced compared to the conventional ones, and the pushing portions 35, 35a, 35
Chain part 35.35a, without clogging b with mud etc.
The planting marks formed by the arm part 35b and the arm part 34 can be made smaller than before, and the planting posture of the seedlings 16 can be maintained in a good manner even when the circular surface is hard, and the seedlings can be tilted. While this can prevent the movable claws 17.17a and 17b from being submerged in water and withering, the movable claws 17, 17a and 17b can be manufactured at a low cost with simple work by bending and welding, and the mold cannot be changed easily as in conventional casting. Compared to processing, planted seedlings 1
For seedling pine properties and planting in No. 6, the push-in portion 35.35 a
, 35b can be easily modified. Therefore, the movable claws 17.17 of the pushing parts 35.35a, 35b differ depending on the planted seedlings 16, the field, etc.
This has practical effects such as being able to be easily changed to A, 17B.
