BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil recovery device for a seed plant for recovering soil in a bed soil filling section of the seed plant.

[0002]

2. Description of the Related Art A conventional seeding plant is equipped with, for example, a bed soil supplying device, an irrigation device, a boring device, a seeding machine, and a soil covering device. , Covering the soil.

[0003]

In the above-mentioned bed soil filling section of the sowing plant, the bed soil surface supplied to the nursery box is scraped off with a leveling brush to receive excess soil in the soil receiving tray. This is sent to a vertical conveyor by a recovery spiral and returned to the hopper in the soil filling section. Although the soil receiving tray is formed in a funnel shape having an inclined surface inclined toward the recovery spiral, there is a drawback that the soil is easily collected on the inclined surface and the recovery device cannot smoothly collect the soil. Therefore, an object of the present invention is to obtain a soil recovery device in a seeding plant in which soil is not accumulated on the slope of the soil receiver.

[0004]

In order to achieve the above-mentioned objects, the present invention provides the following soil recovering apparatus in a seeding plant. That is, in the bed soil filling section of the seeding plant that fills, sows, and covers the bed soil with soil, the soil soil that is scraped off with a leveling brush from the soil bed surface supplied to the nursery box is collected. The funnel is formed with an inclined surface inclined toward the spoiler, and an air nozzle is installed on the upper surface of the inclined surface to blow away the soil that accumulates on the inclined surface toward the recovery spiral with the air. It is a soil recovery device that is characterized by

[0005]

[Operation] The slope of the soil receiving tray that collects the soil that has been scraped off with a leveling brush from the floor soil surface supplied to the seedling raising box at the floor soil filling section in the seeding plant that fills and covers the seedling raising soil The soil collected on the surface is blown off from the upper part of the inclined surface with an air nozzle to facilitate recovery with a recovery spiral.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below. First, a conventional seeding plant will be described. In FIG. 2 and FIG. 3, (1) is an automatic seedling raising box feeder for storing the seedling raising boxes (2) in multiple stages. (4) is a filling conveyor that conveys the seedling raising boxes (2) supplied from the feeding device (1) one by one with the feeding start end side facing below the feeding device (1).
(5) is a bed soil filling machine which is provided at the feeding intermediate portion of the filling conveyor (4) and supplies the bed soil in the bed soil hopper (6) to the seedling raising box (2) on the filling conveyor (4). (7) is a seeding conveyor that is continuously provided at the feed end of the filling conveyor (4). (8) is a vacuum seeder that is provided in the feeding intermediate part of the seeding conveyor (7) and sows the seedling raising box (2) of the soil filling machine on the conveyor. (9) is a soil cover conveyor in which the feed start end is connected to the feed end of the seeding conveyer (7). (1
Reference numeral 0) is a soil cover machine which is provided in the feeding intermediate portion of the soil cover conveyor (9) to cover the seedling-raising seedling box (2) on the conveyor (9) with soil. While being conveyed by the conveyors (4), (7) and (9), the nursery box (2) is configured to be filled with soil, sowed and covered with soil.

The filling machine (5) includes a bed soil supply conveyor (11) for supplying the bed soil in the hopper (6) to the seedling raising box (2).
Pressurized air in the gap between the leveling round brush (12) for leveling the surface of the bed soil supplied to the seedling raising box (2) and the upper end of the seedling raising box (2) when passing through the conveyor (4) after filling the bed soil. Therefore, a compressed air jetting device (13) for jetting and cleaning, and a filling irrigation device (1) for spraying and irrigating the seedling raising box (2) after leveling the soil surface.
4), a vibrator (15) for vibrating the seedling raising box (2) to promote the feeding of the floor soil when the seedling raising box (2) is fed with the soil, and a conveyor (4) below the round brush (12). The recovery conveyor device (17) for returning the floor soil that is dropped to the position and recovered to the hopper (6) through the vertical transfer device (16) and the conveyor (4) below the irrigation device (14). And a drain gutter (18) for filling.

The vacuum seeder (8) is provided with an air compressor (19) and a vacuum pump (20), and the seeding conveyor (7) is driven by a motor (21). The seeds in the seed hopper are vacuumed. It is sucked by a nozzle with suction force, taken out, and seeded in a seedling raising box which is conveyed by a conveyor in order. The soil cover machine (10) is a supply conveyor (23) for supplying the soil cover in the hopper (22) to the seedling raising box (2), and a soil cover irrigation device (24) for spraying water to the whole seedling raising box (2) after the soil covering. ) And the conveyor (9) of the irrigation system (24)
And a drainage gutter (25) for covering the soil that faces the lower position. Therefore, the nursery box is sowed from the automatic nursery box feeder (1) by the floor soil filling machine (8) and covered by the soil cover machine (10). According to the seeding plant as described above, there is a vibrator (15) for vibrating the seedling raising box (2) at the time of supplying the bed soil to promote the supply of the bed soil, and the conveyor (4) of the round brush (12). ) There is a recovery conveyer device (17) for returning the floor soil, which is dropped and recovered by facing the lower position, to the hopper via the vertical transfer device (16), and the overflow portion of the floor soil is recovered.

The present invention relates to the improvement of the soil recovery device in the seed plant as described above. FIG. 1 shows the soil recovery device, which is the same as in FIGS.
2) is a leveling brush, and (17) is a recovery spiral as a recovery device. The illustrated filling conveyor comprises a roller conveyor and is mounted on a machine frame (26). The nursery box (2) is conveyed on this roller conveyor, the soil is supplied from the soil hopper (6), and the leveling brush (12) scrapes off excess soil from the surface of the soil. . In addition to the leveling brush (12), the suspension brush (2
There is 7). The soil receiving tray (28) arranged below the machine frame is provided with a recovery spiral (17) at the bottom for transporting the soil to the vertical transport device (16), and guiding the soil toward this recovery spiral (17). It is formed in a funnel shape forming an inclined surface (28a). An air nozzle (31) is arranged above the inclined surface (28a), and the compressor (3
Air is blown from the air nozzle (31) from 2) via the solenoid valve (33). or,
Before and after the soil receiving (28), rubber hangs (29) from the machine frame.
(30) is provided vertically. Therefore, the air nozzle (3
The air blown from 1) is blown out along the inclined surface (28a), and the soil collected on the inclined surface is collected by the spiral (1).
It is blown away toward 7) and the recovery soil is smoothly collected by the recovery spiral (17). At that time, there is a rubber drip (29) so that the soil is not scattered forward. And the rubber dripping (30) is the watering device (1
Do not let the water from 4) enter the soil receiver (28).

The air is blown out from the air nozzle for several seconds after the seedling raising box has passed through the soil filling section.
Turn on 3) to start blowing. The passage of the nursery box is detected by the sensor and blown, or the soil is supplied and then detected by a timer and blown. or,
A photoelectric sensor may be provided on the soil receiving tray to detect the accumulation of the soil, and the soil may be blown when the soil is detected.
Furthermore, you may make it blow only intermittently. The blowing method is arbitrary and can be modified in design within the spirit of the present invention.

[0011]

According to the present invention, since the air nozzle is provided on the inclined surface of the soil receiving tray, the soil accumulated on the inclined surface of the soil receiving tray can be blown off toward the recovery spiral. Since the soil that hinders transportation can be removed from the inclined surface, the soil can be collected smoothly.
