Description

[Detailed Description of the Invention] The present invention comprises a roll having a paddy storage recess formed on its circumferential surface, a conveyor that collects surplus paddy that overflows from a paddy supply section to the recess, and a conveyor that collects surplus paddy from a paddy discharge section of the recess. In the rotation zone to the supply section,
The present invention relates to a seeding machine equipped with a brush for collecting paddy inside the recess.

Conventionally, in the above-mentioned seeding machine, the conveyor that collects overflowing excess paddy and the brush that collects the paddy stuck in the recess in the rotating zone from the paddy discharge section were each configured as separate devices. However, since the collection brushes and the collection conveyor are further arranged around the roll circumference where brushes for removing excess paddy from the paddy supply section and recesses are arranged, the overall structure becomes extremely complicated. However, there were also disadvantages in terms of production costs.

In view of the above-mentioned circumstances, the purpose of the present invention is to greatly simplify the overall structure and reduce manufacturing costs by rationally improving the paddy collection structure.

The characteristic configuration of the present invention is that in the above-mentioned seeding machine, the conveyor and the brush are composed of a rotating brush in which bristles are helically flocked to a rotating body, and a gutter-like body that conveys the paddy in cooperation with the rotating brush. Its functions and effects are as follows.

In other words, the brush that collects the paddy stuck in the recess is composed of a rotating body with spirally flocked bristles.
The rotating brush and the gutter-like body constitute a collection conveyor, using a feeding action similar to a screw conveyor due to the rotating action of the spiral flocked hair, and one rotating brush can be used as a paddy collecting brush. By using it as a collection conveyor, the overall structure can be greatly simplified and the manufacturing cost can be reduced compared to the conventional configuration in which the collection brush and collection conveyor are separate devices. As a result, it has become possible to provide a compact and inexpensive seeding machine.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

As shown in FIGS. 1 and 2, a seeding roll 4 having a large number of paddy storage recesses 3 arranged in rows on its circumferential surface is provided below a paddy supply hopper 2 equipped with a paddy feeding device 1. At the same time, a first brush 5 is provided at the upper part of the sowing roll 4 to act in rotational contact with the circumferential surface on the upper side of rotation to laterally feed and discharge the paddy excessively accumulated on the sowing roll 4. A second brush 6 is provided which acts in rotational contact with the circumferential surface to prevent surplus rice other than that stored in the recess 3 from being sent as the seeding roll 4 rotates. A blower 7 is provided to apply a suction force for adsorbing stored paddy to all of the rotating recesses 3 over the range from the formed paddy supply section A to the position just before the paddy discharge section B located at the lower end of the seeding roll 4. As the seeding roll 4 rotates, the paddy stored in the recess 3 is suctioned and held in the paddy supply section A and rotated, and then conveyed sequentially by the conveyor 8 below the roll 4 in the paddy discharge section B. Seedling raising box 9
The seeding machine is configured to feed the stored paddy by dropping it sequentially.

The first brush 5 is constructed by attaching bristles 5b forming the brush to a rotating body 5a that is parallel to the rotational axis of the roll 4 and rotates in a direction opposite to the rotational direction of the roll 4. The length of the bristle body 5b in the bristle-flocked state is adjusted so that the outer circumferential locus of rotation of the rotating brush 5 slightly overlaps the outer periphery of the roll 4 when viewed in the direction of the rotational axis. The width of the rotating body 5a is the same over the entire width of the rotating body 5a.

A gutter-like body having a shape along the rotation outer circumferential trajectory of the rotating brush 5 when viewed in the direction of the rotation axis Q, the lower end of which is close to the circumferential surface of the roll 4, and the upper end of which is located above the entire rotating brush 5. 10 is provided on the lower side of the rotating brush 5 over its entire width, and the paddy overflowing from the paddy supply section A is fed horizontally as the spiral rotating brush 5 rotates.
By cooperating with the guide action of the trough-like body 10, the material is conveyed horizontally like a screw conveyor, and is collected in a collecting section 11 attached to the conveying end of the trough-like body 10.

In addition, by making the outer circumferential locus of the rotating brush 5 wrap around the circumferential surface of the roll 4, rice grains adhere to the inside of the recess 3 without being discharged from the chaff discharge part B due to electrostatic action or adhesive action due to moisture. The structure is such that the paddy that is being rotated and transferred is scraped out from the recess 3 by the rotating action of the rotating brush 5, and the scraped out paddy can be transported and recovered in the same manner as described above.

In other words, by equipping one rotary brush 5 with both the conveyor function for conveying and recovering overflowing paddy and the cleaning function for scraping out adhering paddy from the recess 3, two devices each having these functions can be used. The overall structure is simplified compared to the case where the

In addition, the specific spiral pitch of the spiral rotating brush 5,
Further, the specific lap dimensions with the roll 4, etc. can be changed as appropriate.

This invention is a stationary type that uses seedling boxes as the target for sowing,
This applies to various types of seeding machines, including mobile types for direct sowing.
