Abstract

A seeding machine with a seed meter and a seed delivery system for moving seed from a seed meter to a furrow formed in the soil. The delivery system has an endless member moving in a housing about pulleys to move seed from an upper opening in the housing to a lower discharge opening. In one embodiment, a loading wheel at the upper opening to the housing engages seed on a metering disk to move seed into the housing. The metering disk and housing can be arranged in planes parallel to one another.

First claim

The invention claimed is:

1. A seeding machine, comprising:
at least one seed metering system; and
at least one seed delivery system, each said at least one seed delivery system being in communication with the corresponding said at least one seed metering system, each said at least one seed delivery system including
a housing having an upper opening for receiving seed from said corresponding at least one seed metering system and a lower opening through which seed is discharged; and
a brush belt within said housing disposed around a first drive pulley and a second idler pulley, said brush belt having a plurality of bristles with distal ends at an inner surface of said housing and moving therealong as said brush belt is driven from said upper opening, where the seed from said at least one seed metering system is entrapped by said plurality of bristles and said housing, to said lower opening to convey seed to said lower opening and discharge seed therethrough.

2. The seeding machine as defined by claim 1 wherein a speed of the distal ends of said plurality of bristles as seed is captured therein is lower than a speed of the distal ends of said plurality of bristles when seed is discharged.

3. The seeding machine as defined by claim 1 further comprising a loading wheel at said housing upper opening opposite seed on said at least one seed metering system from said plurality of bristles to capture the seed therebetween.

4. The seeding machine as defined by claim 3 wherein said at least one seed metering system includes a disk and wherein said loading wheel is driven by said disk.

5. The seeding machine as defined by claim 1 wherein seed is inserted into said plurality of bristles in a direction parallel to the length of said plurality of bristles.

6. The seeding machine as defined by claim 1 wherein seed is inserted into said plurality of bristles in a direction substantially perpendicular to the length of said plurality of bristles.

7. The seeding machine as defined by claim 1 wherein seed is inserted into said plurality of bristles in a direction at an angle to the length of said plurality of bristles.

8. The seeding machine as defined by claim 7 wherein seed is inserted into said plurality of bristles in a direction at an angle to the length of said plurality of bristles of approximately sixty degrees.

9. The seeding machine as defined by claim 1 wherein said at least one seed metering system includes a metering member to which the seed is adhered by air pressure and wherein the seed is removed from the metering member at least in part by said plurality of bristles.

10. The seeding machine as defined by claim 1 wherein the seed from said at least one seed metering system is entrapped by said plurality of bristles and said housing as said plurality of bristles close upon themselves as the brush belt transitions from a curved path to a linear path.

11. A planter row unit comprising:
a seed metering system adapted to discharge seeds at regular intervals; and
a seed delivery system including:
a housing having an upper opening for sequentially receiving seed from said seed metering system and a lower opening through which seed is discharged; and
a brush belt within said housing disposed around a first drive pulley and a second idler pulley, said brush belt having a plurality of bristles with distal ends at an inner surface of said housing and moving therealong as said brush belt is driven from said upper opening, where the seed from said seed metering system is entrapped by said plurality of bristles and said housing, to said lower opening to convey the seed to said lower opening and discharge seed therethrough.

12. The planter row unit as defined by claim 11 wherein a speed of the distal ends of said plurality of bristles as seed is entrapped therein is lower than a speed of the distal ends of said plurality of bristles when seed is discharged.

13. The planter row unit as defined by claim 11 wherein seed is inserted between said plurality of bristles in a direction parallel to the length of said plurality of bristles.

14. The planter row unit as defined by claim 11 wherein seed is inserted into said plurality of bristles in a direction substantially perpendicular to the length of said plurality of bristles.

15. The planter row unit as defined by claim 11 wherein seed is inserted into said plurality of bristles in a direction at an angle to the length of said plurality of bristles.

16. The planter row unit as defined by claim 15 wherein seed is inserted into said plurality of bristles in a direction at an angle to the length of said plurality of bristles of approximately sixty degrees.

17. The planter row unit as defined by claim 11 wherein said seed metering system includes a metering member to which the seed is adhered by air pressure and wherein the seed is removed from the metering member in part by said plurality of bristles.

18. The planter row unit as defined by claim 11 wherein the brush belt defines a seed path along which seed is accelerated in a horizontal direction rearward relative to said housing to a speed approximately equal to a forward speed of travel of the planter row unit.

19. The planter row unit as defined by claim 11 wherein the seed from said seed metering system is entrapped by said plurality of bristles and said housing as said plurality of bristles close upon themselves as the brush belt transitions from a curved path to a linear path.
