The angle (α) is set to the same angle as the angle of the rear side surface (1a) of the feeding recess (1) opened at regular intervals around the seed feeding roll (A). The angle (α) is about 25 degrees.

  Along the bottom plate (4), the seeds in the seed rectification unit (27) fall into the feeding recess (1) of the seed feeding roll (A). In the feeding recess (1), The feed free space (31), which is the main part of the present invention, is configured so as not to be pressed strongly or pushed in at a density higher than necessary. The front side surface (1b) of the feeding recess (1) has a larger inclined surface than the rear side surface (1a) so that the seed entrance (19) gradually opens with respect to the feeding recess (1). Equipped. As shown in FIG. 3, the angle of the front side surface (1b) is such that it is perpendicular to the lower side of the shielding plate (2) suspended from above, so that the seed (S) is smoother. It drops into the feeding recess (1).

  The main part of the present invention is that the number of seeds introduced into the feeding recess (1) is accurately set to a constant number, and when the seeds are coated seeds, they are pressed against the scraping brush (3). In order to prevent the coating portion from being destroyed, the coating portion is constructed so as to be dropped at a relaxed and constant density.

  Therefore, the seed before being thrown into the feeding recess (1) is forcibly pushed into the feeding recess (1) as the seed feeding roll (A) rotates counterclockwise in FIG. Thus, the present invention is configured as shown in FIG.

  That is, the seed feeding roll of the seed drop inlet (19) prevents the seed (S) that has slowly fallen into the feeding recess (1) from being pressed and dropped. A shielding plate (2) is provided above (A). By providing the shielding plate (2), a seed free space (31) that does not receive a pressing force from the seed inlet (19) portion of the seed rectifying section (27) is formed.

Depending on the type of seed (S), moisture content, and type of coated seed, the seed free space The amount of seed (S) that can move to (31) can be adjusted.

  By forming the seed free space (31) with the scraping brush (3) by the shielding plate (2), the seed (S) dropped into the feeding recess (1), It is a free space in which the pressure on the seed (S) is released so that no more seed (S) is pushed in. Next, even when the surface of the feeding recess (1) is shaved by the scraping brush (3), the seed (S) moves in the space of the feeding recess (1) which is loose, and the scraping brush ( It is configured to escape from the pressing force of 3).

  Conventionally, the scraping brush (3) is forcibly scraping off the excess seed (S) of the seed (S) piled up in the feeding recess (1) to adjust the number of grains. The amount of seeds (S) was adjusted. However, in the present invention, the scraping brush (3) is used so that the number of grains is accurately fixed and the coating seed film is not scraped off without applying pressure to the seed (S) in the feeding recess (1). ) Is provided with a shielding plate (2) and a feed free space (31) so that the pressing force is not applied directly to the seed (S).

  Since the seed free space (31) is configured, the pressing force of the scraping brush (3) against the seed (S) is limited, the number of seed grains is precisely set to a constant number, and the coated seed is damaged. The effect of the present invention is not exhibited.

  The scraping brush (3) is configured as shown in FIGS. 2 and 7 to 9. That is, as shown in FIG. 2, a scraping brush base (3a) and a main part of the scraping brush (3) are provided, and a scraping brush adjusting hole (on the side of the seed hopper (H)) ( 11) The tip of the scraping brush (3) is finely adjusted by rotating and adjusting the scraping brush adjusting screw (10) provided in the upper portion after the scraping brush base (3a) is inserted. It is possible to do. Moreover, the width | variety seen from the side surface on the outer periphery to the feeding roll (A) of the scraping brush (3) is configured to be sufficiently larger than the width in a side view of the feeding recess (1) on the outer periphery of the feeding roll (A). Yes. Thus, the scraping brush (3) can reliably close the feeding recess (1).

  Further, as shown in FIG. 4, a biasing spring (32) is interposed in the scraping brush adjusting hole (11), and the scraping brush (3) is scraped off by the biasing spring (32). ), When there is a pressing force from the seed (S), the scraping brush (3) can escape. Further, in FIG. 5, the scraping brush (3) is configured to come into contact with the feeding roll (A) with its own weight, and the scraping brush adjusting screw (10) is the top of the scraping brush (3). It is configured only to restrict upper positions. Thus, the effect of preventing the seed (S) from being damaged can be obtained by reducing the pressing force of the scraping brush (3) on the feeding roll (A).

  Also, a roll surface guide plate (5) is attached from the scraping brush (3) to the rear side in the rotation direction G of the seed feeding roll (A) so as to follow the arc of the seed feeding roll (A). ing. The roll surface guide plate (5) and the seed feeding roll (A) prevent the seed (S) in the feeding recess (1) from falling to the seed drop opening (20) early. Immediately after the scraping brush (3), at the position where the roll surface guide plate (5) starts, the seed (S) can be smoothly moved from the scraping brush (3) to the roll surface guide plate (5). Therefore, as shown in FIG. 4, a guide surface (5a) is formed. The guide surface (5a) may be formed in an arc shape or may be formed in an inclined shape that becomes gradually narrower. The seed (S) that is not damaged by the scraping brush (3) is configured not to be damaged by the roll surface guide plate (5).

  In FIG. 2, the seed feeding roll (A) includes a roller drive shaft (29) that is driven by power from a drive force transmission chain case (21) that transmits the rotation of the drive force extraction roller (22). The center of the roller drive shaft (29) is the axis (O). The roll surface guide plate (5) is below the horizontal surface (L) passing through the axis (O) of the roller drive shaft (29) from the rear surface of the scraping brush (3) by an angle (β). It extends to the position. The angle (β) is approximately 30 degrees. Since the seed (S) in the feeding recess (1) is allowed to fall freely below a certain angle (β) from the horizontal line (L) passing through the axis (O) of the roller drive shaft (29). is there.

  The roll surface guide plate (5) is pivotable in the direction of escape when the pressing force from the seed (S) increases, and is pivotally supported by the upper pivotal support portion (5b). Yes. Further, the roll surface guide plate (5) itself is made of an elastic body such as sponge, and is movable in a direction to escape by the pressing force from the seed (S). However, the seed (S) holding power can be maintained at any time. Further, a roll chamber lower plate (13) connected to the bottom plate (4) is provided, and a roll chamber lower plate gap (13a) is formed between the roll chamber lower plate (13) and the seed feeding roll (A). ing. The roll chamber lower plate gap (13a) is used to eliminate unnecessary friction between the seed feed roll (A) and the roll chamber lower plate (13).

  7 to 9 disclose a configuration of the relationship between the scraping brush (3) and the outer periphery of the seed feeding roll (A). The scraping brush (3) is formed in an arc shape along the seed feeding roll (A) in a side view as shown in FIG. 8 so as to be exactly along the outer periphery of the seed feeding roll (A), and is shown in FIG. Thus, when it sees from the rotation direction G of a seed delivery roll (A), it is comprised linearly so that the outer peripheral surface of a seed delivery roll (A) may be met.

  In FIG. 10, the difference between the state in the case of dropping seeds and fertilizer by the feeding device of the present invention and the state of dropping by the conventional feeding device is shown. In the present invention, since the front side surface (1b) of the feeding recess (1) provided in the feeding roll (A) is configured in an inclined direction, the feeding roll (A) rotates and finally When the seed (S) in the feeding recess (1) falls off from the roll surface guide plate (5), the seed (S) gathers in the front side surface (1b) of the feeding recess (1). Since it falls all at once, it falls side by side in a short direction with respect to the traveling direction, as shown in “main mechanism” in FIG.

  In the case of the conventional feeding device, the “stock length” is created long in the direction of travel, so it is impossible to clearly open between the stocks, and wind and air cannot pass between the stocks. It will interfere. In the case of the present invention, it is possible to reliably obtain between the strains, so that the division of paddy rice is improved. In addition, a sufficient amount of stock can be formed to pass a weeding vehicle after rice planting, so that it is possible to advantageously advance the weeding of rice.
