Description

[Detailed Description of the Invention] The present invention relates to a preliminary seedling retrieval device in a walk-behind rice transplanter having a rearward-inclined seedling stand.

Conventionally, a spare seedling storage container has been constructed of a box body, a pair of left and right brackets protruding from the lower front surface of the box body, and a pin fixed to the tips of the brackets. A lateral groove into which the pin fits and an inclined guide surface following the lateral groove are provided at the front part of the holder, and a lateral groove into which the front end of the spare seedling container moved rearward is fitted and an engagement groove into which the pin engages are provided at the rear part. so that when taking out the spare seedlings, the front end of the spare seedling storage container and the pin are engaged with the rear lateral groove and the engagement groove, so that the spare seedling storage container is held in a backward tilted position with a distance from the seedling stand. A rice transplanter according to the present invention is already known from Japanese Utility Model Application Publication No. 53-21923.

However, as mentioned above, the known rice transplanter has a very complicated structure of the spare seedling storage container and the upper surface of the machine body, and the machining thereof is troublesome, resulting in a significantly high cost. ,
Simply fitting the front part and the pin attached to the bracket into the horizontal groove and the engagement groove is extremely unstable, and the engagement will come off during seedling extraction, causing the spare seedling stand to fall, which will only hinder the extraction work. It was extremely dangerous.

Furthermore, the spare seedling storage container requires means for engaging with the horizontal grooves, that is, a pair of right and left brackets and pins fixed to the brackets, so the seedling box cannot be used as it is as a spare seedling container, and a special structure is required. Therefore, when supplying seedlings, it is necessary to take out the seedlings from the seedling box, transfer them to a spare seedling stand with the above-mentioned special configuration, and then take them out again and supply them to the seedling stand. As a result, a large amount of seedling supply is required. There were problems such as the need to transfer the seedlings twice, which caused the bed soil for the seedlings to collapse.

Although the present invention has an extremely simple structure and can be obtained at low cost, it can reliably support the front and rear parts of the seedling box, and allows the roots of the pine seedlings to grow out from the holes in the bottom of the seedling box. The purpose of the present invention is to provide a spare seedling retrieval device for a rice transplanter, which can easily take out pine seedlings that are difficult to take out, or even pine seedlings that are poorly rooted and easily lose their shape, while reducing the collapse of the floor while remaining at the handle position. In a rice transplanter in which a seedling stand is installed along a handle that is tilted backwards, and a spare seedling stand for mounting a seedling box is installed on the body in front of the machine, the seedlings are placed at the rear end of the spare seedling stand. A receiver is provided which is lower than the mounting part and has a concave portion open at the top and rear.The upright surface formed at the front end of the concave portion of the receiver is used as a receiving surface for receiving the front end surface of the seedling box, and the bottom surface is used as the receiving surface for receiving the front end surface of the seedling box. The lower surface of the front is used as a receiving surface to support, and the opening toward the rear is made to directly face the partition wall of the seedling stand. It is characterized by a structure in which the box is supported upwards at the rear.

The embodiment shown in the drawings will be explained below.1
is a fuselage in which an engine 2 is mounted on the front, a handle 3 tilted so that the rear side is higher is fixed to the rear, a float 4 is attached to the lower part, and wheels 5, 5 are arranged on both the left and right sides, At the front of the handle 3, a seedling stand 6, which is tilted backwards like the handle 3, is installed so as to be able to reciprocate in the lateral direction. Planting rod 7,
7 is provided.

Further, a spare seedling stand 8 is provided on the upper part of the machine body 1, and a seedling box 10 in which pine seedlings 9 are stored in a raised state is placed on the above-mentioned spare seedling stand 8.

A receiver 11 is provided at the rear end of the preliminary seedling stand 8, which has an L-shaped cross section, has side walls 11a, 11a at both ends, and has a recess that is open at the top and rear. When taking out the seedlings, the concave portion has a front end upright surface that receives the front end surface of the seedling box 10 when taking out the seedlings, a bottom surface that serves as a receiving surface that supports the lower surface of the seedling box 10, and an open portion at the rear that supports the seedling box 10. Since it faces the stand 6 directly, when the number of pine seedlings 9 in the seedling stand 6 is low, simply pull the seedling box 10 towards the rear and the front end of the seedling box 10 will automatically fit into the recess of the receiver 11. Since they are fitted, when the rear part is lowered in that state, the lower surface of the rear end rests on the partition wall 12 located in the middle of the seedling stand 6, and is supported in the rear upward position. In this state, the operator stands behind the handle 3, inserts the scraper 13 from behind between the pine seedlings 9 and the bottom plate of the seedling box 10, and takes out the pine seedlings 9.

At this time, the front part of the seedling box 10 is supported by the receiver 11 and prevented from moving forward, and the rear part is supported by the partition wall 12 of the seedling stand 6, so the scraper 13 is strongly pressed. The pushed-in seedling box 10 does not move forward.

In the above-described embodiments, when the scraper 13 is not required, for example, when the seedling box 10 is used to store the pine seedlings 9 and used only for supplying spare seedlings, and when the seedling board is used, the steps other than the process of using the scraper 13 are the same. Seedlings can be supplied.

Another embodiment will be explained with reference to FIG. 4. The above-mentioned embodiment was a walk-behind rice transplanter for planting two rows as shown in the drawing, but this example is a walk-behind rice transplanter for planting four rows. It is equipped with two upper and lower spare seedling stands 8, 8, and the device for supporting the seedling box 10 when replenishing seedlings is constructed in the same manner as in the previous embodiment. When replenishing seedlings, the seedling box 1
The front end corner of the seedling box 10 can be easily fitted into the recess of the receiver 11 by pulling the seedling box 10, placing its front part on the receiver 11, and pulling it backward to slide it.

It goes without saying that the present invention can also be applied to a walking type rice transplanter for planting five or more rows.

As described above, the present invention is a rice transplanter in which a seedling stand 6 is provided along the handle 3 which is tilted backwards, and a spare seedling stand 8 on which a seedling box 10 is mounted is arranged on the body in front of the rice transplanter. A receiver 11 consisting of a recess that is lower than the seedling rest and open at the top and rear is provided at the rear end of the seedling stand 8, and the upright surface formed at the front end of the recess of the receiver 11 is connected to the front end of the seedling box 10. The bottom surface is used as a receiving surface to support the front lower surface of the seedling box 10, and the opening toward the rear directly faces the partition wall of the seedling stand 6, so that the rear end of the preliminary seedling stand 8 Since the seedling box 10 is supported upwardly at the rear by the receiver 11 and the upper part of the partition wall 12 of the seedling platform 6, when replenishing the seedling platform 6 with spare seedlings, it is easy to remove the hand from the rear driving section. By extending the seedling box 10 on the preliminary seedling stand 8 and pulling it rearward, placing the front part of the seedling box 10 on the receiver 11 and shifting it backward, the front end of the seedling box 10 can be moved without special care. It automatically fits into the recess of the receiver 11, and when the rear part of the seedling box 10 is lowered in this state, it easily rests on the partition wall 12 of the seedling stand 6, and the seedling box 10 can be moved with a simple operation. Moreover, the seedling can be taken out quickly.

Moreover, when taking out seedlings from the seedling box 10 using the scraper 13, since the seedling box 10 is supported downwardly in the front, the scraper 13 can be easily pushed diagonally forward and downward to separate the seedlings.
1 supports the front part of the seedling box 10 and receives the front wall of the seedling box 10 by the front end surface of the recessed part, so that the work of taking out the seedlings can be carried out more stably and easily.

Furthermore, since the seedling box used for raising seedlings can be used as is and used as a seedling container, there is no need to prepare anything special, and the structure for supporting the seedling box is the same as described above. Since the method is extremely simple, manufacturing costs can be significantly reduced.
