Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a scraper in a seeding device for a seedling nursery box.

(Prior Art) Conventionally, a seedling raising box was provided with a conveyor for transferring the seedling raising box, a soil covering supply device provided above the transferring conveyor, and a scraper for scraping the edge of the seedling growing box provided above the transferring conveyor. The seeding device was developed in 1987.
It is described in Publication No. 91453.

(Problems to be Solved by the Invention) The above-mentioned known method had a problem in that soil remained attached to the scraper and the work had to be stopped to remove it.

(Means for solving the problem) The present invention includes a transfer conveyor 1 for seedling growing boxes 2 and a covering soil supply device 17 provided above the transfer conveyor 1.
and a scraper 20 for scraping the edge of the seedling growing box 2 provided above the transfer conveyor 1. It is formed into an L-shaped side surface consisting of a lower plate 22, and a left-right rotating shaft 23 is fixed to the upper end of the upper plate 21, and both ends of the rotating shaft 23 are rotatable on supports 25 provided on the transfer conveyor 1. This is a scraper in a seedling box seeding device which is pivoted on the seedling box 2 and collides with the support column 25 with an impact when it comes off the edge of the seedling box 2 and rotates downward.

(Structure) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a horizontal transfer conveyor that transfers the seedling growing box 2 from the starting end side 3 to the ending end side 4, and is formed long in the direction in which the seedling growing box 2 is transferred. It is supported on the floor by support legs 5 provided at desired positions. The seedling growing box 2 is made of synthetic resin and is shaped like a square drawer.

At a position near the starting end side 3 of the transfer conveyor 1,
A bed soil supply device 6 is provided. The bed soil supply device 6 is formed by a bed soil supply hopper 7, a soil supply belt, a soil supply amount adjustment device 8, etc., and supplies bed soil into the seedling raising box 2. 9 is a motor, and 10 is a floor soil receiving box.

A pump 11 is installed on the downstream side of the bed soil supply device 6.
Irrigation section 12 provided with an irrigation nozzle connected to
will be established. 13 is a water receptacle.

A seed rice supply device 14 is provided on the downstream side of the irrigation section 12 from which the water is transferred. The seed rice supply device 14 includes a hopper 1
5, a seed feeding roll, a seed feeding amount adjusting device 16, and the like.

A covering soil supply device 17 is provided on the downstream side of the transfer side of the seed rice supply device 14. The covering soil supply device 17 is the hopper 1
8 and a soil supply belt are formed by a soil supply amount adjusting device 19 and the like, and supply sieved soil for covering soil into the seedling raising box 2.

Thus, a scraper 20 is provided at a position of the soil covering supply device 17 after the soil covering operation is completed. The scraper 20 is integrally formed with an upper plate 21 and a lower plate 22 that are long in the left and right direction of a thin metal plate, and is L-shaped when viewed from the side. A horizontal rotation shaft 23 is fixed to the upper end of the upper plate 21, and both ends of the rotation shaft 23 are attached to support plates 25 attached to the frame 24 of the transfer conveyor 1.
It is rotatably attached to the shaft.

The scraper 20 is always urged to rotate downwardly about the rotating shaft 23 by its own weight or spring elasticity. The lower edge of the lower plate 22 is a working part, which is formed to be larger than the interval at which the support plate 25 is provided, and contact parts 26 are protruded from both left and right sides of the support plate 25, and the lower edge of the lower plate 22 is a working part. When the scraper 20 simultaneously scrapes and cleans both upper surfaces and rotates downward, the abutting portion 26 impacts the support plate 25 and stops the downward rotation of the scraper 20.

Reference numeral 27 denotes a guide plate, which is provided at the inner central portion of the rear surface of the scraper 20. The rear end portion 28 of the guide plate 27 is in a vertical state before making contact with the front end portion 28 of the seedling raising box 2 so as to smoothly rotate the scraper 20 upward when the front end portion 29 of the seedling raising box 2 comes into contact with the rear end portion 28 .

30 is a guide roll for transporting the seedling raising box 2; 31 is a motor for rotating the guiding roll 30; and 32 is a rear end portion of the seedling raising box 2.

(effect) Next, we will discuss the effect.

When the seedling raising box 2 is placed on the guide roll 30 on the starting end side 3 of the transfer conveyor 1, the seedling raising box 2 is transferred toward the terminal end side 4 by the guide roll 30, and is supplied with bed soil by the bed soil supply device 6. The soil is irrigated by the irrigation unit 12, sown at the lower part of the rice seed supply device 14, and is supplied with sieved soil for covering soil at the lower part of the soil covering supply device 17.

The seedling raising box 2 that has been supplied with the sieved soil for covering soil is moved forward by the guide rolls 30, and when the front end 29 of the seedling raising box 2 comes into contact with the guide plate 27 of the scraper 20, the guide plate 27 is vertically moved. Even if the lower plate 22 of the scraper 20 is inclined forward toward the lower end and gets caught, the front end 29 of the seedling raising box 2 can smoothly push the rear edge 28 of the guide plate 27 forward. The scraper 20 is smoothly rotated upward around the rotating shaft 23.

Since the scraper 20 is always urged to rotate downward about the rotating shaft 23 by its own weight or spring elasticity, the front end 29 of the seedling box 2
When the scraper 20 slips below the lower edge of the lower plate 22, the upward rotation of the scraper 20 stops, and the lower edge of the lower plate 22 comes into close contact with the edge of the seedling box 2.

Since the scraper 20 is formed to be larger than the width of the seedling growing box 2, when the seedling growing box 2 moves forward, the width of the seedling growing box 2 increases.
The upper surfaces of the edges on both sides are rubbed at the same time to clean the accumulated soil and taken out onto the lower plate 22. In this case, the scraper 20 consists of an upper plate 21 and a lower plate 22, and is L-shaped when viewed from the side, so the lower end of the lower plate 22 is slightly closer to the front in the forward direction than the upper end, as shown in FIG. Since it will be located in the area, it should be cleaned well.

Since the scraper 20 is always urged to rotate by its own weight or spring elasticity, when the rear end 32 of the seedling box 2 passes below the lower edge of the lower plate 22, the edge of the seedling box 2 The lower edge of the lower plate 22, which was in close contact with the upper surface, begins to rotate downward. Since abutting portions 26 are protrudingly formed on both left and right sides of the lower plate 22 of the scraper 20, when the abutting portions 26 rotate downward, they collide with the rear edge of the support plate 25 with an impact. Therefore, the soil adhering to the inner part of the scraper 20 is removed with an impact.

Therefore, sowing can be done continuously.

(Effects) Conventionally, for a seedling growing box, which is equipped with a conveyor for transferring the seedling growing box, a soil covering supply device provided above the transferring conveyor, and a scraper that scrapes the edge of the seedling growing box provided above the transferring conveyor. The seeding device was developed in 1987.
It is described in Publication No. 91453.

The above-mentioned known method had a problem in that soil remained attached to the scraper and the work had to be stopped to remove it.

However, in the present invention, the transfer conveyor 1 for the seedling raising boxes 2
In the seedling box seeding device, which is provided with a soil covering supply device 17 provided above the transfer conveyor 1, and a scraper 20 for scraping the edge of the seedling growing box 2 provided above the transfer conveyor 1, scraper 20
is made of a thin metal plate and has an L-shaped side surface consisting of an upper plate 21 and a lower plate 22 that are long in the left and right directions, and a left-right rotating shaft 23 is fixed to the upper end of the upper plate 21.
3, both ends of which are rotatably pivoted to pillars 25 provided on the transfer conveyor 1, and the seedling-growing box 2 collides with the pillars 25 with impact when it comes off the edge of the seedling-growing box 2 and rotates downward. Since the scraper 20 is used as a scraper in a seeding device, the scraper 20 is made of a thin metal plate and is easy to process.

The scraper 20 is formed into an L-shaped side surface consisting of an upper plate 21 and a lower plate 22 that are long in the left and right directions.A left-right rotating shaft 23 is fixed to the upper end of the upper plate 21, and both ends of the rotating shaft 23 are moved. Since the scraper 20 is rotatably attached to a support 25 provided on the conveyor 1, when the scraper 20 acts on the edge of the seedling box 2, the lower end of the lower plate 22 protrudes in front of the upper end. Clean well.

In addition, the lower plate 22 of the scraper 20 is attached to the seedling box 2.
Since the lower plate 22 is designed to collide with the pillar 25 with an impact when it comes off the edge and rotates downward, the soil attached to the lower plate 22 can be automatically removed.

This effect is achieved.
