Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a portion for supplying seedlings such as straw grass to a seedling mounting table of a transplanter, and more specifically, to a reliable vertical structure in a structure for mounting seedlings on a seedling mounting table together with a supply box. A technique for obtaining a feeding function.

[0002]

2. Description of the Related Art For example, in the strawberry transplanter disclosed in Japanese Patent Laid-Open No. 5-3711, a seedling pushing tool (reference numeral 21) that engages with upper left and right side walls of a seedling supply box (reference numeral 4) can be slid. It is known that a technology for supporting seedlings by pushing down the seedlings by its own weight is provided. In other words, instead of matting like rice seedlings, with rose seedlings that are separated one by one like straw grass seedlings, the forced feeding force of the vertical feed mechanism is hard to be transmitted to the upper seedlings, so seedlings that slip off By pushing with a pusher, the seedlings can be fed vertically without fail.

[0003]

However, the seedlings that come into contact with the seedling pushing device do not always have a uniform surface state, and they may hit unevenly on the left and right sides. There is a risk that the vehicle will not be able to reliably push the back because it will lean to the left and right and will be caught, resulting in a situation where the back pushing function is not fully exhibited. In addition, the seedling pushing device itself may be inclined and may not be able to slide down smoothly. An object of the present invention is to enable the seedling pushing function of the seedling pushing tool to be exerted without the above-mentioned inconvenience so that the seedlings can be reliably fed vertically.

[0004]

[Means for Solving the Problems] To achieve the above object, the present invention is configured so that a seedling supply box capable of placing and storing crop seedlings can be inserted into a seedling placement table, and the seedling supply box in the inserted state is provided. The front wall and the bottom plate on the seedling supply side are configured to be openable, and the seedling supply box is provided with an engaging portion that is engageable with the vertical feed endless rotation zone equipped on the seedling mounting table. Drive the vertical feed endless rotation band by engaging the vertical feed endless rotation band when the seedling supply box is inserted into the seedling placement table and the bottom plate is opened by deploying the push tool. In order to enable the seedling pushing tool to forcibly boost the crop seedlings, the seedling pushing tool is equipped so as to be slidable forward and backward with respect to the seedling supply box.

[0005]

The above-mentioned structure is forcibly pushing the seedlings by forcibly feeding the seedling pushing tool by the vertical feed endless rotation belt. That is, the seedling supply box can be inserted into the seedling placement table, and the front wall and the bottom plate can be opened to enable the seedling supply, and the seedling pushing tool can be engaged with the vertical feed endless rotation band. Therefore, by driving the vertical feed endless rotation band in that state, the seedling pushing tool can be forcibly fed longitudinally, and even if the rear end faces of the seedlings are not aligned, the seedling pushing tool can reliably push the seedling. In addition, this prevents the seedling pushing tool itself from tilting and causing poor movement.

That is, by using the mechanism of the vertical feed endless rotation band originally provided for feeding seedlings and engaging with the pushing of seedlings, the seedling pushing tool can be forcibly driven without using a new drive mechanism. It became like this.

[0007]

As a result, the seedlings on the seedling table can be forcibly and vertically fed by the structure devised to engage the endless rotary belt for vertical feeding and the seedling pushing tool to forcefully feed the seedlings, and the rose seedlings and other rose seedlings are missing. It was possible to provide a seedling supply unit suitable for planting operation without planting.

[0008]

Embodiments of the present invention will be described below with reference to the drawings in the case of a transplanter for strawberries which is an example of crop seedlings. FIG. 1 shows a straw transplanter, 1 is a traveling machine body, 2 is an engine bonnet, 3 is a preliminary seedling storage stand, 4 is a seedling supply box on which the stocked strawberries are placed, 5 is a seedling stand, 6 Is a planting mechanism for picking up and planting seedlings one by one from the lower end of the seedling stand 5. In this straw transplanter, the seedlings are supplied to the seedling supply box 4
Along with this, a structure for mounting on the seedling placing table 5 is adopted. Next, the seedling supplying section will be described.

As shown in FIGS. 2 to 6, the seedling supply box 4 is
It is composed of left and right side walls 4a, 4a, a front wall 4b, a rear wall 4c having an insertion portion with a lower half or more omitted, a bottom plate 4d, a seedling pushing tool 7, and an insertion / extraction plate 8. The bottom plate 4d has a shape in which a large hole for allowing the later-described vertical feeding mechanism 9 and the seedling pushing tool 7 to engage with each other is formed, and can be swingably opened / closed about the horizontal axis P at the lower end of its front end (openable). ) A short front wall 4b is pivotally supported.

The seedling pushing tool 7 is composed of a bent plate having a sliding contact surface 7a, a pressing surface 7b, and a pair of left and right engaging pins (corresponding to engaging portions) 7c, 7c. It is a plate-shaped member having a pair of vertical grooves 8a, 8a for passing 7c. The insertion / removal plate 8 is mounted on the bottom plate 4d by insertion / removal from the insertion portion below the rear wall 4c, and the left and right portions of the bottom plate 4d serve as rail portions 10 for insertion / removal of the insertion / removal plate 8. Therefore, when the insertion / removal plate 8 is removed, the bottom plate 4d almost disappears, that is, the bottom plate 4d can be opened.

At the front ends of the left and right side walls 4a, 4a, a detent portion 12 which is partially inflated to maintain the closed front wall 4b in its closed posture is formed, and near the rear wall 4c. Opening / closing lever 1 supported on the side wall 4a of the
The front wall 4b and the front wall 4b are interlockingly connected by a rod 13, and the front wall 4b can be freely opened and closed by swinging the opening / closing lever 14.

On the other hand, the feed belt (corresponding to an endless rotation band) 11 of the vertical feed mechanism 9 has a long feed surface over substantially the entire length of each row 5A of the seedling placing table 5, and is slightly larger than the seedling placing surface 5a. A pair of left and right long holes 11a are formed so as to be arranged in a protruding state and into which the engagement pins 7c of the seedling pushing tool 7 can be inserted.

Next, an actual seedling supply operation procedure will be described.
First, as shown in FIG. 3 (a) or FIG. 4, the seedlings are mounted with the insertion / extraction plate 8 mounted and inserted into the seedling placing table 5, and then,
The insertion / extraction plate 8 is pulled out rearward and removed [the state of FIG. 3 (b)], and then the seedling pushing tool 7 is finely adjusted so that the engaging pin 7c fits into the long hole 11a at the upper end of the seedling supply box 4. Set (Fig. 5). When the planting work is started and the vertical feed mechanism 9 is activated, the seedling pushing tool 7 moves downward integrally with the feed belt 11 to forcibly push the seedlings, and the seedlings are partially slid during the sliding movement. The seedlings can be sent well without the inconvenience of stopping.

When a seedling remaining amount sensor (not shown) is activated to supply a new seedling, the seedling pushing box 7 can be removed at the same time by pulling out the seedling supply box 4, and then a new seedling supply can be supplied. The box 4 should be attached according to the above procedure,
Replacing the seedling supply box 4 is easy.

[Other Embodiment] As shown in FIG. 7, a rear wall 4c is provided.
A structure may be employed in which the left and right side walls 4a, 4a between the bottom plate 4d and the bottom plate 4d are formed in an open shape without connecting portions, and the seedling pushing tool 7 is set in a state of being opposite to the front and back when the seedlings are mounted. With this means, since the sliding contact surface 7a faces backward, there is an advantage that the seedlings can be pushed to the end as compared with the one in this embodiment.

The front wall 4b and the bottom plate 4d may be opened by sliding the front wall 4b upward to allow passage of seedlings, or by removing the bottom plate 4d and making the insertion / extraction plate 8 correspond to the bottom plate. It should be configured as possible. Also, the feed belt 11
The seedling pushing tool 7 may be configured to be forcibly fed by forming a protrusion on the seedling pushing hole and forming a long hole in the seedling pushing tool 7.

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