DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling rest on which seedlings are placed, and the seedlings of the seedling rest are taken out from a seedling take-out port in conjunction with a reciprocating transverse drive of the seedling rest and planted in a field. The present invention relates to a seedling planting device having a planting claw and a vertical feed mechanism for feeding a seedling on the seedling stand to a seedling removal exit side when the seedling stand reaches the end of a horizontal feed stroke.

[0002]

2. Description of the Related Art Conventionally, in the seedling planting apparatus having the above-mentioned structure, the foremost seedling of a group of seedlings placed on a seedling rest is connected to a guide rail provided and fixed in front of the lower end of the seedling rest. It is common to configure so that the seedlings received above and located above the seedling removal outlet are removed by the planting claws.

[0003]

In the above-mentioned conventional structure, when the seedling positioned above the seedling removal outlet is taken out by the planting claw, if the division of the seedling is not reliably performed,
Subsequent seedlings may be dragged by the extracted seedlings, which may make the size and posture of the extracted seedlings unstable.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to reliably and stably take out and plant seedlings at each time and to make the structure therefor simple and robust. And

[0005]

In order to achieve the above object, a seedling planting apparatus according to the present invention is arranged and fixed in front of a lower end portion of the seedling stand in the seedling planting apparatus having the above-mentioned structure. A seedling receiving member is provided on the guide rail, which is formed by integrating a plurality of vertical walls extending cantilevered forward with a predetermined lateral interval with a horizontally long base member, and this seedling receiving member is integrated with a seedling rest. It is characterized in that it is attached to the seedling rest side so as to be able to move laterally.

[0006]

According to the above construction, the vertically fed seedlings are guided on the seedling receiving member, and are laterally moved integrally with the seedling rest while being supported on the seedling receiving member. The seedlings located are taken out by the planting claws and planted in the field. In this case, among the seedlings on the seedling rest, the foremost one is supported by the upper end of the vertical wall group of the seedling receiving member, and the seedling taken out by the planting claws and the subsequent seedling are separated by the vertical wall. . Therefore,
Subsequent seedlings are prevented from being dragged by the removed seedling. Also, since the vertical wall group and the horizontally long base member arranged side by side in the horizontal direction have an integral structure, for example, compared to a structure in which each vertical wall is individually attached to the seedling mounting side, the structure is It can be easily, securely and firmly attached to the seedling platform.

[0007]

Therefore, according to the present invention, the following effects can be obtained. By providing a group of vertical walls that move laterally together with the seedling rest at the lower end side of the seedling rest, the extracted seedlings can be reliably divided into a predetermined size, and the posture of the seedlings is lost due to dragging of the subsequent seedlings. It can be planted stably without the need. Since a plurality of vertical wall groups are integrated into a horizontally long base member to form a seedling receiving member, the structure and installation are simpler than when each vertical wall is independently mounted on the seedling mounting side,
Moreover, it is robust and durable as a whole.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a seedling planting device 4 of a rice planting machine in which a pot seedling W obtained by growing seedlings on a pot sheet 2 having a structure in which a pot portion 1 having a top-upped shape is arranged vertically and horizontally is placed on a seedling rest 3. ing. The seedling planting device 4 includes a seedling rest 3, a lateral feed mechanism (not shown) that intermittently reciprocates the pot by one pot in the left-right direction while supporting the seedling rest 3, and a seedling rest. Fixed guide rail 5 for receiving pot seedlings W on table 3
And a planting claw 7 that is driven to rotate up and down in a fixed locus while passing through a seedling outlet 6 formed in the guide rail 5.
And a belt-type vertical feed mechanism 8 with a protrusion. As shown in FIGS. 3 and 4, a long float 10 before and after supporting the machine body 9 is disposed below the walking-type machine body 9 equipped with the seedling planting device 4. Notches 13, 13 are formed on the left and right sides of the float 10 so that the swing fulcrum of the transmission cases 12, 12 with respect to the traveling wheels 11, 11 can be lowered.

As shown in FIGS. 1 and 2, a seedling receiving member 14 having an upper edge extending from the seedling mounting surface A of the seedling rest 3 is provided at the lower end of the seedling rest 3. Is mounted so as to be able to move laterally integrally with the seedling mounting table 3. The seedling receiving member 14 is provided with a plurality of vertical walls 14a extending in a cantilever shape in a forward direction and arranged in parallel at a predetermined horizontal interval corresponding to the horizontal width of the pot 1. It has a structure in which a horizontally long base member 14b attached to the table 3 is integrated. And these vertical walls 1
4a, the lower edge thereof is configured to be in contact with the seedling outlet 6 forming surface 5a of the guide rail 5, and the leading edge of the vertical wall 14a receives the front edge of the pot 1. The receiving portion 15 is protruded upward, and a pot 1 subsequent to the front row pot 1 is provided on an upper edge near the base end of the vertical wall 14a.
Is provided with a non-slip projection 16 for preventing the seedling from being pulled in when removing the seedling. Therefore, the adjacent vertical walls 14a,
14a and the guide rail 5, a space S is formed. In the front row pot 1, each pot 1
Is supported on the vertical wall 14a and the front edge of the pot 1 is received by the receiving portion 15, so that the pot 1 does not directly contact the guide rail 5 so that the pot 1
Does not shift with the movement of the seedling placing table 3. Then, even if the floor soil falls from the pot 1, the soil will rest on the guide rails 5 in each space S, and the space S faces the seedling outlet 6 with the reciprocating lateral movement of the seedling rest 3. When this happens, soil and the like will be discharged from the seedling outlet 6.

[0010] In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the structure shown in the attached drawings.
