Description

[Detailed description of the invention] The present invention provides a first preliminary seedling stand for placing and storing pine-shaped preliminary seedlings within the width of the cover, on the bonnet located in front of the control section, and The present invention relates to a spare seedling storage device for a walk-behind rice transplanter, in which a second spare seedling rest with a wide width extending laterally from the first preliminary seedling rest is arranged above the first spare seedling rest.

In a walk-behind rice transplanter, the left and right propulsion wheels are placed relatively close to the left and right outer sides of the machine cover, so as mentioned above, the first reserve seedling stand on the lower level is housed within the width of the cover so that it does not interfere with the wheels. The second one on the top that doesn't
The stand for holding spare seedlings is made wide and extends to the left and right sides, so that it can accommodate as many spare seedlings as possible.

In this case, when driving without storing spare seedlings, for example, when loading and unloading from the field from the ridge using footboards, or when loading and unloading onto a transport vehicle, the lower front of the left and right sides of the machine, especially in front of the propulsion wheels, should be kept in good condition. In order to be able to see through the seedlings, it is common to construct a wide secondary seedling stand that extends above the propulsion wheel with a frame made of thin rods, or with a lattice or mesh seedling placement surface. It is becoming.

However, since the pine-shaped seedlings must be stored in the seedling tray with a framework made of sticks, it is difficult to transfer the pine-shaped seedlings to the seedling pedestal of the seedling planting device. It had the disadvantage of being time consuming. On the other hand, the above-mentioned disadvantages have been solved with a spare seedling stand having a lattice or mesh seedling placement surface because it can directly place and accommodate pine-shaped seedlings. Because all of the seedling placement surfaces were structured in a lattice or mesh pattern, bed soil that fell from the pine-shaped seedlings placed on the seedling placement section that overlapped above the first preliminary seedling placement table in the lower tier caused the soil to fall down. In some cases, it fell through the lattices and meshes and fell onto the seedlings stored in the lower tier. In addition, in order to prevent the pine-shaped seedlings from drying out and to make them slide smoothly on the seedling stand of the seedling planting device, the preliminary seedlings may be sprinkled with water in advance. The dripping water also poured through the lattices and meshes onto the seedlings stored in the lower tier, and the seedlings in the lower tier were sometimes supplied with more water than they needed, making the bed soil more likely to collapse.

The purpose of this invention is to solve the above-mentioned drawbacks of directly storing pine-shaped preliminary seedlings without using a seedling growing box, and in the preliminary seedling storage device having the above-mentioned configuration, the second preliminary seedling A group of openings for viewing forward and downward is provided only on the seedling placement surface in the side projecting portion of the seedling placement platform, and the entire center seedling placement surface overlapping above the first preliminary seedling placement platform is configured as a plate surface. It is characterized by:

According to the above configuration, when traveling without storing spare seedlings, it is possible to safely maneuver by looking forward and downward on both the left and right sides of the aircraft through the group of openings provided on the left and right overhangs of the upper wide spare seedling stand, Moreover, since this group of openings is formed only in the overhang, the pine seedlings housed in the first preliminary seedling stand in the lower tier are not covered with crumbling soil or water, and the seedlings housed in the lower tier are protected. Now I can do it.

Examples will be described below based on the drawings.

As shown in FIG. 1, an engine 2 and a transmission case 3 are directly connected to the front end of a main frame 1 that also serves as a transmission case, and a
A row-planting seedling planting device 4 is connected and a control section 8 is disposed behind it to constitute a body of a walking rice transplanter, and one front float 5 is disposed below the front of this body. In addition, three rear floats 6 are arranged in parallel in the left and right direction of the machine below the seedling planting device 4, and transmission cases 7, 7 which are vertically swingable are arranged on the left and right sides of the transmission case 3. A pair of propulsion wheels 8, 8 are provided. The front float 5 is also configured to serve as a ground pressure detection sensor that swings up and down around the front end in accordance with fluctuations in ground pressure, and the front float 5 detects ups and downs of the machine body due to changes in the depth of the tiller. Based on this detection result, a pair of transmission cases 7
The plant is equipped with a well-known control mechanism that automatically controls the elevation and descent of each using a drive mechanism to maintain a stable level of the machine body relative to the planting surface.

The seedling planting device 4 comprises four sets of pine-shaped seedlings A placed on a seedling platform 9 arranged in a forward downward tilted position, and moved back and forth horizontally at a constant stroke, while cyclically moving up and down at the front position of the lower end. 10 planted nails
The structure is such that one seedling is cut out from each plant and planted in four rows. Further, a spare seedling storage device 12 is arranged above the rear half of the bonnet 11 arranged along the upper part of the machine, and the preliminary seedling storage device 12 is configured as shown in FIG. A pair of gate-shaped frames 13 are attached to the left and right lateral sides of the bonnet 11, respectively, in a state extending in the front-back direction, and between these frames 13, a pine-shaped preliminary seedling A' is directly placed and stored on the top surface of the bonnet. A spare seedling stand 14 is provided, and a second wide second seedling stand 15 on which three pine-shaped preliminary seedlings A' are placed side by side in the width direction is attached above these frames.

This second preliminary seedling stand 15 is constructed as an integrally molded plastic product, and has three seedling placing surfaces a, b, and c partitioned by ribs 16 on its upper surface. It is being The central seedling placement surface a, which overlaps above the first preliminary seedling placement platform 14, has a flat surface on its entire surface, and is stretched laterally to the right and left of the first preliminary seedling placement platform 14. A large number of groups of horizontally elongated slit-shaped openings 17 are formed in parallel in the front and rear on the left and right seedling placement surfaces b, b. opening 17
Through the group, it is possible to see forward and downward, particularly the forward path of the propulsion wheels 8, 8.

Further, a horizontally long rib 20 is integrally formed to project downwardly from the rear side edge of each opening 17, and
The slitted seedling placement surfaces b, b are reinforced, and the ribs 20 prevent muddy water splashed up from the propulsion wheels 8 from scattering upward through the openings 17 and staining the surrounding area. There is. In other words, the left and right projecting portions of the second preliminary seedling stand 15 function as wheel fenders.

Note that the groups of openings 17 for viewing forward and downward on the left and right seedling placement surfaces b, b of the second preliminary seedling placement stand 15 do not necessarily have to be horizontally long slits, but may also be provided with a group of vertically long slits or a group of lattice holes. good. Also, the second
The central seedling placement surface a and the left and right seedling placement surfaces b, b of the preliminary seedling placement table 15 may be configured as separate structures.
