Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a so-called walking-type rice transplanter, which is operated by a worker while walking.

[Problems to be solved by conventional techniques and inventions] In conventional walk-behind rice transplanters, as disclosed in Japanese Utility Model Application Publication No. 52-158026, the body of the rice transplanter has a
Attach a pipe member extending rearward from the front engine, insert the rope of the recoil starter into this pipe member, and lock the hand handle at the end of the rope of the recoil starter to the tip of this pipe member. By doing so, the hand handle can be pulled from the operating handle position of the rice transplanter. However, in the prior art, the rope guide and the member having the hand handle locking function are attached to a long pipe. Since it is made up of several parts, it not only increases costs, but also because the rope attached to the recoil starter slides against the inner wall of the pipe over a long distance, making it susceptible to damage, especially when foreign objects such as mud and water get inside the pipe. If the recoil starter gets in, the damage will be extremely severe and the rope will have poor durability, and if the rope in the recoil starter is damaged, it will take a lot of effort to replace it with a new part. This required a lot of effort.

The present invention aims to solve these problems.

[Means for Solving the Problems] In a walk-behind rice transplanter equipped with an engine with a recoil starter in the front part of the machine body, and a backward-tilting seedling stand and a control handle in the rear part of the machine body, a rope of the recoil starter is provided. A receptacle for removably inserting and guiding the recoil starter is provided only at a position in front of the seedling stand that can be operated from the control handle position, and a hand handle connected to the end of the rope of the recoil starter is located at the rear of the aircraft. It is held in the receiver so that it can be pulled towards.

[Operations and effects of the invention] With this configuration, the operator can pull the hand handle of the recoil starter while remaining at the control handle position at the rear of the rice transplanter; in other words, the engine can be started remotely from the control handle at the rear of the rice transplanter, and by simply removing the rope from the receiver, the rope can be removed with the handle still attached to it, and the handle can be removed from the handle at hand. The work of replacing the rope with handle can be done extremely easily compared to the case of the prior art.

Further, the receiver for guiding the rope through the rope is disposed only in front of the seedling stand and at a position where it can be operated from the operating handle position. The distance that the rope slides into contact with the receiver during starting is reduced, and the situation where the rope comes into sliding contact with the receiver with foreign matter attached can be avoided as much as possible, improving the durability of the recoil starter. It is possible to do so.

As described above, according to the present invention, when starting the engine of a rice transplanter using the recoil starter can be performed remotely from the control handle position at the rear of the rice transplanter, there is no increase in costs, and the recoil starter can be started by the recoil starter. This has the effect of improving the workability of maintenance such as parts replacement for a rope with a hand handle, and also improving the durability of the rope.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.A rice transplanter body 6 designated by the reference numeral 1 in the figure has an engine equipped with a recoil starter 19 for manual starting in the front part of the transmission case 2. 3 is mounted, and a transmission case 5 is connected to the rear of the transmission case 2 via a frame 5' containing a built-in drive shaft. A float 7 and a pair of left and right side floats 8 are provided, and wheels 9 are provided on both left and right sides of the machine body 6 to support the machine body, and the rice transplanter 1 is moved in the direction of arrow A by these wheels 9. It is composed of

At the rear end of the frame 5', a seedling loading device 12 comprising a rearward tilting seedling loading stand 10 and the transmission case 5 is provided, as well as a pair of left and right operating handles 13.

Both wheels 9 are each attached to the tip of a swing arm 14 that is rotatably attached to a boss portion 15 at the base of the transmission case 2, and
The transmission case 2 is driven by a belt 16 from the transmission case 2 through a chain in the arm, and
A belt 17 from the engine 3 is placed on the top surface of the frame 4.
A driven hydraulic pump 18 is provided.

Further, on the upper surface of the frame 5', a preliminary seedling mounting stand 11 on which preliminary seedling mats are placed is erected via a plurality of supports.

Furthermore, a starting rope 2 with a diameter d pulled out from the recoil starter 19 of the engine 3
A hand handle 21 is connected to the rear end of 0.

Of the respective columns of the preliminary seedling platform 11 provided at the front position of the seedling platform 10, only the outermost column 11' in the lateral direction with respect to the traveling direction of the rice transplanter 1 is provided with a receiving metal fitting 22. is attached, and the handle 21 is held in the receiving metal fitting 22 so that the hand handle 21 can be pulled in the direction of the operating handle 13 at the rear. It is configured as shown in Figure 4. That is, a metal bar or the like whose starting end 23' is welded and fixed to the support 11' is bent and wound into a ring shape at least once so that the terminal end 23'' overlaps the starting end 23'. A loop portion 23 is formed that is large enough that the hand handle 21 cannot pass through, and the rope 20 is inserted through this loop portion 23. Between the starting end 23' and the ending end 23'' which overlap in the loop portion 23, Open passages 24 are provided at appropriate intervals S in the axial direction of the rope 20, and the interval S between the opening passages 24 is equal to or slightly larger than the diameter d of the rope 20, and the rope 20 is bent at right angles. As you can see,
In other words, the receiving metal fitting 22 is configured such that the rope 20 can be inserted into the receiving metal fitting 22 in a detachable manner.

In this configuration, in order to start the engine 3 when running the rice transplanter in a field, etc., the operator extends his hand from the operating handle 13 side, holds the hand handle 21 held on the receiving metal fitting 22, and presses the fourth By vigorously pulling the rope 20 in the direction of arrow B in the figure, the recoil starter 19 to which the base of the rope is attached rotates, and the engine 3 is started.
After the start, when you release your hand from the hand handle 21, the return spring built into the recoil starter 19 causes the rope 20 to move from the hand handle 21 to the receiving metal fitting 2.
It gets caught up until it touches 2.
