Cartridge spreader system
View Patent ↗The cartridge spreader system includes a mobile cartridge spreader with a cartridge station configured to engage a cartridge and includes a locking controller for locking the cartridge securely into the cartridge station. The cartridge station includes an activator mechanism for activating and deactivating an engaged cartridge. The cartridge spreader includes an activation controller for activating and deactivating the cartridge. Activation of the cartridge allows the granular product contained in the cartridge to flow out of the container, through a granular chute on the cartridge station, and onto a granular product launcher which launches or impels the granular product over terrain or other surface. When the cartridge is deactivated, the flow path is sealed stopping the flow of granular product. The cartridge itself includes a fitment that engages with the cartridge station. The cartridge fitment includes an appropriately sized metering gate.
1. A manually removable cartridge containing granular lawn care product or other granular applications, comprising:
a container for holding a granular product;
a fitment, functionally joined to the container, configured to engage a cartridge station of a spreading device, comprising:
a fitment shell configured to be joined to an end of the container that comprises a structural arrangement configured to engage with the cartridge station;
an agitator mechanically coupled to an agitator drive shaft in the fitment that is configured to mechanically engage a driver mounted in the spreading device;
a flow metering gate, comprising an aperture, configured to allow flow of the granular product; and
an activator configured to activate and deactivate the flow of the granular product out of the container, wherein the activator comprises a sliding shutoff plate.
2. The cartridge according to claim 1 , wherein the container is flexible.
3. The cartridge according to claim 1 , wherein the container is rigid.
4. The cartridge according to claim 1 , wherein the flow metering gate is configured to allow the granular product to flow at a predetermined, constant rate.
5. The cartridge according to claim 4 , wherein the rate of flow is dictated by a predetermined size of the aperture.
6. The cartridge according to claim 5 , wherein the size of the aperture is predetermined in accordance with the type of the granular product contained in the container.
7. The cartridge according to claim 1 , wherein the container is sealed upon deactivation.
8. The cartridge according to claim 1 further comprising the agitator being configured to rotate inside the container to agitate the granular product.
9. The cartridge according to claim 1 , wherein the container is semi-rigid.
10. The cartridge according to claim 1 , wherein the granular product comprises ice melting granules, fertilizer, pesticides, granular soil amendment material, granular oil absorbent material, dusting products, granular floor cleaning product, grass seed, or combinations thereof.
11. The cartridge of claim 1 , wherein the spreading device is an agricultural device.
12. The cartridge of claim 11 , wherein the agricultural device is a lawn and garden device.
13. A manually removable cartridge containing granular lawn care product or other granular applications, comprising:
a container means for holding a granular product;
a fitment means for engaging a cartridge station of a spreading device, comprising:
a fitment shell means for mating an end of the container with the cartridge station;
a means for agitating the granular product in the container mechanically coupled to a drive shaft in the fitment that is configured to mechanically engage a driver mounted in the spreading device;
a flow metering means for allowing flow of the granular product from the container; and
an activator configured to activate and deactivate the flow of the granular product out of the container, wherein the activator comprises a sliding shutoff plate.
