  In such a configuration, the gist of the present invention is that a water dripping plate 50 is interposed between the seedling tray T and the cover ring 33. Hereinafter, the configuration of the water dripping receiving plate 50 will be described in detail with reference to the drawings.

  As shown in FIG. 3, the pair of left and right handle support frames 15, 15 are provided with the above-described lateral transport mechanism support frames 97, 97 that extend in the left-right direction. Each horizontal transport mechanism support frame 97 is formed in a “U” shape in plan view with a front frame piece 97a, a horizontal frame piece 97b, and a rear frame piece 97c. The left and right lateral transport mechanism support frames 97, 97 are fixed to the handle support frames 15, 15 with the open end portions of the front frame piece 97a and the rear frame piece 97c facing each other.

  A plate-like bracket 51 is suspended from the middle portion of the front frame piece 97a of each of the horizontal transport mechanism support frames 97 described above. A support bracket 52 having a substantially inverted L-shaped cross section is connected to the plate-like bracket 51 in a rearward direction, and a front end portion of the water dripping receiving plate 50 is placed on the support bracket 52. The dripping receiving plate 50 is fixed by bolts and nuts 53.

  The water dripping receiving plate 50 is fixed by the bolts and nuts 53 at the time of use, but is provided so that the bolts and nuts 53 can be removed and replaced when they are damaged or aged.

  In this way, the water dripping receiving plate 50 is attached to the above-described lateral transport mechanism support frames 97, 97, which are feed mechanism frames, via the plate-like bracket 51 and the support bracket 52, so that the lateral transport mechanism support frame is provided. Since the seedling stage 40 is disposed near 97 and 97, water dripping from the seedling stage 40 can be reliably received.

  Further, the cover ring 33 is provided to be movable in the vertical direction so as to correspond to the unevenness of the field, but the position in the front / rear / left / right direction is fixed. The positional relationship with the direction does not fluctuate, and the water dripping receiving plate 50 can cover only the minimum necessary portion of the covering ring 33, which is advantageous in terms of cost and weight reduction.

  Further, when the water dripping receiving plate 50 is attached to the attachment frame of the cover ring 33, there is a risk that the vertical movement due to the follow-up of the cover ring 33 to the saddle surface U may be hindered, but this is a feed mechanism frame that supports the seedling tray feed mechanism. Since it is attached to the horizontal transport mechanism support frames 97, 97, the above problem can be solved.

  Moreover, the water dripping receiving plate 50 has a plate shape as a whole, and has a rectangular shape in plan view. It has a rectangular shape in plan view, and is formed so as to cover the entire covering ring 33 with the rectangular shape.

  That is, the water dripping receiving plate 50 is formed so that its left and right width is at least larger than the overall left and right width in the projection plane of the pair of left and right cover rings 33, and its front and rear width is at least in the projection plane of the pair of left and right cover rings 33. It is formed larger than the entire front-rear width. As a result, the entire pair of covering rings 33 can be covered from above, and water falling from the seedling tray T can be prevented from directly attaching to the covering rings 33.

  Moreover, the water dripping receiving plate 50 uses a flexible material such as rubber, for example, so that the structure below the seedling stage 40 is complicated and the shape is deformed by the flexible material even in a narrow space. A drooping receiving plate 50 can be present.

  In this way, the water drop receiving plate 50 between the seedling tray T and the cover ring 33 is interposed, so that the water falling from the seedling mount 40 is received by the water drop receiving plate 50, so that the cover ring 33 is wet. It is possible to prevent water from adhering.

  Moreover, as shown in FIG. 3, the seedling stage 40 on which the seedling tray T is placed is provided so as to be inclined rearward and upward so that the lowermost part S of the seedling stage 40 is positioned above the cover ring 33. is doing. Thus, since the lowest part S of the seedling stage 40 is located above the covering ring 33, the covering ring 33 gets wet directly by receiving the water dripping from the lowermost part S by the dripping receiving plate 50. Can be prevented.

  Further, the water dripping receiving plate 50 has a front end fixed to the lateral transport mechanism support frame 97 by bolts and nuts, and a rear end edge thereof is not fixed to the lateral transport mechanism support frame 97 but a free end. Thus, by fixing the front part of the water dripping receiving plate 50, it is possible to prevent water from falling in front of the cover ring 33.

  Further, as shown in FIG. 3, the front end edge B of the water dripping receiving plate 50 is located in front of the lowermost part S of the seedling mount 40 and is located in front of the front end edge B of the cover ring 33. Therefore, the covering ring 33 can be prevented from getting wet with water.

  Further, as shown in FIG. 3, the position of the seedling pot P when the seedling tray T is forwardly fed by the vertical transport mechanism 35 and the front end edge B of the water dripping receiving plate 50 are made substantially the same. . In this way, water is prevented from dripping from the seedling tray T to the front of the cover ring 33.

  In addition, even when the seedling tray T is located at the rear lower side, water may be dripped, but since the seedling tray T at that time is located behind the soil covering ring 33, the water dripping from the seedling pot P There is no possibility that the cover ring 33 gets wet or the soil in front of the cover ring 33 gets wet with water.

  Further, by making the rear end edge a free end, as shown in FIG. 3, it can be arranged along the shape of the handle support frames 15 and 15 extending rearward and upward. In this way, the water dripping receiving plate 50 can be present even in a narrow space where the structure below the seedling stage 40 is complicated.

  Furthermore, the water dripping receiving plate 50 forms at least the front edge B at a position higher than the central portion and the rear portion, which are other portions, so as not to dripping water dripping from the seedling tray T to the front of the lower covering ring 33. It can also be configured. Thereby, water can be reliably dropped to the rear of the machine body without attaching water to the front of the cover ring 33. Then, water can be prevented from adhering to the soil covering ring 33 by dripping water in front of the soil covering ring 33 to wet the soil.

  Further, the drooping receiving plate 50 can be formed with a concave curved surface at its substantially central portion. That is, the water dripping receiving plate 50 has its front end edge B positioned at the uppermost position, the substantially central portion positioned at the lowest position, and the rear end edge positioned between the front end edge B and the substantially central portion, The substantially central portion can be formed as a concave curved surface. Thereby, the water from the seedling tray T can be reliably received by the concave curved surface described above. Further, since at least the front part is positioned higher than the concave curved surface, the concave curved surface allows water to flow reliably to the rear of the cover ring 33.

  As a result of the above, the seedling transplanting machine according to the first embodiment interposes the soil containing water and water dripping when the irrigated seedling tray T is placed on the seedling mount 40 between the seedling tray T and the cover ring 33. Since it is received by the provided water dripping receiving plate 50, the covering ring 33 can be prevented from getting wet.
