Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising mat automatic feeding device for feeding and loading seedling raising mats made of rock wool or the like into a seedling raising box instead of bed soil.

[0002]

2. Description of the Related Art In recent years, studies have been conducted on the use of milk seedlings as seedlings for rice transplanters, and since these seedlings have insufficient rooting, they are different from conventional seedlings, medium seedlings, and adult seedlings. Since the continuous mat seedling cannot be formed due to the root entanglement, the above-mentioned seedling raising mat is used because the floor material itself needs to have the function of the continuous mat.

As a means for supplying and loading this seedling raising mat to a seedling raising box, a mat storing portion for storing a large number of seedling raising mats is provided, and one seedling raising mat is placed from the mat storing portion in the seedling raising box conveyed by the seedling raising box conveyor. It has been proposed to provide a mat feeding means for feeding the seedlings one by one, and in order to configure this mat feeding means, the mat feeding means directly feeds the seedling mats from the mat accommodating section one by one directly into the nursery box on the nursery box conveyor. It was configured to be supplied by dropping into.

[0004]

However, if the seedling raising mat is simply dropped and supplied from the mat storage section into the seedling raising box which is conveyed by the seedling raising box conveyor, the timing for conveying the seedling raising box and dropping and supplying the seedling raising mat is improved. It was not possible to expect that the seedling-growing mat was loaded into the seedling-growing box in a predetermined state with only a slight deviation, and there was room for improvement in terms of loading performance of the seedling-growing mat into the seedling-growing box. It is also possible to prevent loading mistakes by using the intermittent feeding method in which the seedling raising box is stopped when the seedling raising mat is dropped and supplied, but this is slow in working speed and lower in processing capacity, which is a practical problem. there were.

The present invention has been made by paying attention to such a situation, and provides an automatic seedling raising mat feeder for surely and efficiently loading the raising seedling mat without shifting while continuously transporting the raising seedling box. The purpose is to do.

[0006]

A feature of the present invention is to provide a mat accommodating portion for accommodating a large number of seedling mats, and one mat for each seedling from the mat accommodating portion in a nursery box conveyed by a nursery box conveyor. In the automatic seedling raising mat supply device provided with a mat supplying means for supplying, the mat supplying means is configured so that the mat sending means receives the seedling growing mats dropped one by one from the mat storing section and conveys them in the same direction as the nursery box conveyor. A mat conveyor is provided, and a mat pushing guide means for pushing the seedling raising mat from the mat conveyor in the same direction as the seedling raising box conveyor is pushed into the seedling raising box on the seedling raising box conveyor, and the mat pushing guide means is conveyed. The speed is set higher than the transport speed of the nursery box conveyor.

[0007]

Function: That is, the seedling raising mat dropped from the mat accommodating section is once received by the mat conveyor, the received seedling raising mat is conveyed in the same direction as the seedling raising box conveyor by the mat conveyor, and the mat pushing guide means causes the seedling raising mat to be raised from the mat conveyor. The mat is configured to be pushed into the nursery box on the nursery box conveyor from the tip side while conveying in the same direction as the nursery box conveyor, and the transport speed of the mat pushing guide means is set higher than the transport speed of the nursery box conveyor. By doing so, even if there is some deviation between the timing of feeding the nursery box and the drop supply of the nursery mat, the mat conveyor and mat pushing means can exert the timing correction function, and the nursery mat can be surely raised without any gaps. Can be loaded in the box.

[0008]

As a result, the seedling raising mat can be surely loaded into the seedling raising box in a predetermined state, and the seedling raising mat is much more excellent in loading performance into the seedling raising box, and the seedling raising can be operated with high work efficiency. An automatic mat supply device can now be provided.

[0009]

EXAMPLES As shown in FIG. 1, a floor material such as rock wool was cut into a fixed shape on the upper part of a nursery box conveyor 2 on which a nursery box 1 is placed and continuously conveyed horizontally at a constant speed. A mat accommodating portion 4 for accommodating the seedling-growing mats 3 in a stacked state is provided.

The nursery box conveyor 2 has a large number of drive rollers 2.
a is arranged in parallel on the roller conveyor, and the seedling raising boxes 1 are supplied one by one from the known seedling raising box automatic feeder on the left side outside the figure, and the seedling raising boxes are fed to the known seeding apparatus on the right side outside the figure. 1 is supplied.

The mat accommodating portion 4 is constructed such that the seedling-growing mats 3 are stacked between guides 5 which are arranged and fixed in the front, rear, left and right directions so that the mats can be lowered by their own weight. A feeding means 6 and a mat conveyor 7 that receives the dropped seedling raising mat 3 and conveys it in the same direction as the seedling raising box conveyor 5 are provided.

The mat feeding means 6 is constructed by providing a large number of needles 6b piercing the front and rear ends of the seedling raising mat 3 on the outer periphery of a rotating body 6a which can be driven to rotate downward. In the stopped state, the seedling-growing mats 3 can be dropped one by one by holding the seedling-growing mats 3 group and rotating them by a predetermined angle.

The mat conveyor 7 includes a plurality of drive rollers 7.
a is arranged horizontally, and a mat pushing-in guide means 8 for pushing the seedling-growing mat 3 from the mat conveyor 7 into the seedling-growing box 1 is provided behind it.

The mat pushing guide means 8 has a plurality of driving rollers 8a arranged so that the rearward ones are closer to the nursery box conveyor 2, and the seedling mat 3 from the mat conveyor 7 is in the same direction as the nursery box conveyor 2. It is configured to be pushed into the nursery box 1 on the nursery box conveyor 2 from the tip side while being transported to.

Then, the conveying speed of the mat conveyor 7 and the mat pushing guide means 8 is set to be higher than the conveying speed of the seedling raising box conveyor 5, so that the timing of the feeding of the seedling raising box 6 and the drop feeding of the seedling raising mat 1 may be slightly different. Even if there is a gap,
The mat-conveyor 7 and the mat pushing-in guide means 8 are used to ensure that the seedling-growing mat 3 is loaded into the seedling-growing box 6 in a predetermined state by a timing correction function.

A contact or optical mat presence / absence sensor 9 for detecting the presence or absence of the seedling raising mat 1 on the mat conveyor 7 is provided, and the seedling raising mat 3 has disappeared on the mat conveyor 7 based on the information from the sensor 9. When it is detected, the control means 10 for intermittently driving the mat feeding means 6 so as to drop only one seedling-growing mat 3 from the mat housing portion 4 is provided, and the seedling-growing mat 3 is transferred to the continuously-raised seedling-growing box 1. It is configured so that it can be continuously supplied.
