Abstract

A hand-planter for singulation planting of cereal, grain, seed and other crops includes a tapered soil engagement component for striking and penetrating a soil surface. With each planter strike to the soil surface, the planter is actuated to meter a granular material product by reciprocating a drum to rotate, thereby exposing a cavity to a material hopper. As the actuation force is released, the reciprocating drum rotates in an opposite direction to its original location and drops the material that has been metered.

First claim

What is claimed is:

1. A metering device, comprising an external housing including a linear slot therein; a hopper segment within said external housing, said hopper segment configurable to accept a dispensable material therein; a rotatable lever supported at one end by said external housing; said lever including a cam receiver; a reciprocating drum housing coaxial with said external housing and extending at least partially into said external housing; a reciprocating drum supported in said reciprocating drum housing, said reciprocating drum including a cam and a cavity, wherein said cam is engaged with said cam receiver through said linear slot, wherein initial rotation of said reciprocating drum causes said cavity to come into communication with said hopper and to acquire a dispensable amount of said material therein, and, wherein further rotation of said reciprocating drum causes said dispensable amount of said material to be deposited on the ground.

2. The metering device of claim 1 further including a pin secured to said external housing wherein said lever includes a guide slot for receiving said pin.

3. The metering device of claim 2 wherein said lever is capable of simultaneous reciprocating and rotational motion with respect to said external housing.

4. The metering device of claim 2 wherein said external housing includes a plate for supporting said pin.

5. The metering device of claim 1 further including a soil engagement component.

6. The metering device of claim 5 wherein said soil engagement component is supported from said external housing.

7. The metering device of claim 1 wherein said cavity is shaped for metering a product.

8. The metering device of claim 1 wherein said reciprocating drum including a first end and a second end; said cam extending from said first end and a rotational support on said second end; said reciprocating drum housing includes a channel for receiving said reciprocating drum and a rotational hole for receiving said rotational support.

9. A singulating hand planter for distributing a material, comprising:
a. an external housing, said external housing containing a cylindrical interior;
b. a reciprocating drum housing positionable to be at least partially within said interior of said housing and in alignment therewith, said reciprocating drum housing being longitudinally movable with respect to said external housing;
c. a hopper internal to said external housing, said hopper at least for containing the material;
d. a reciprocating drum mounted within said reciprocating drum housing and containing at least one cavity therein, whereby said longitudinal motion of said reciprocating drum housing with respect to said external housing urges the reciprocating drum into rotation, thereby causing said cavity to come into communication with said hopper thereby acquiring a dispensable amount of said material therein and to depositing said acquired material into the soil.

10. A singulating hand planter for distributing a material, comprising:
a. an external housing having a central axis and having a hollow interior;
b. a reciprocating drum housing aligned with said central axis of said external housing and being longitudinally movable along said central axis with respect to said external housing, said reciprocating drum housing having a terminus positionable to be within said external housing interior during said longitudinal movement;
c. a hopper internal to said external housing, said hopper at least for containing the material;
d. a reciprocating drum mounted within said reciprocating drum housing and containing at least one drum cavity therein, whereby said manually initiated longitudinal movement of said reciprocating drum housing with respect to said external housing urges the reciprocating drum into rotation, thereby causing said drum cavity
i. to rotate into communication with said hopper,
ii. to acquire a dispensable amount of said material from said hopper therein, and
iii. to deposit said acquired material onto the ground.

11. The singulating hand planter according to claim 10 wherein said hopper is internal to said reciprocating drum housing.
