Patent for Sale:Underground Material Dispenser
The material dispenser is driven into the ground by rotating the shaft and flange. The helical flange-shaft arrangement allows for deep ground penetration if desired. The device can be designed to receive a tool that rotates the shaft and helical flange to drive the device into the ground. This way, the device can be driven into the ground using a tool such as a power tool. This option is favorable when the material dispenser has a relatively long shaft. Alternatively, the device has a hand-grip for driving the device into the ground by hand. This option may be favorable when the material dispenser has a relatively short shaft.
Our novel material dispensing device also has a receptacle attached to one end of the hollow shaft. Material to be dispersed into the ground is placed in the receptacle. The receptacle sits above ground for ease of use and maintenance. The height of the receptacle can be relatively short to avoid damage from equipment such as lawn mowers. Various lid options are available which permit easy monitoring and re-filling of the receptacle content.
The material placed in the receptacle can be a fertilizer. In other uses, the material contains a copper compound or derivative for retarding root growth to protect underground structures from root damage. Still other kinds of materials may be placed in the receptacle. Regardless, the material or a liquid-material mixture dissolved from at least a portion of the material flows from the receptacle into the hollow shaft. The material or the liquid-material mixture is dispersed into the ground through one or more openings formed in the shaft and/or helical flange. Providing openings in the helical flange portion of the dispenser widens the dispersal radius.
Primary Application of the Technology
Nurseries can use this novel material dispenser to safely and efficiently fertilize plant inventory.
Utility, cable and telephone companies can use our novel material dispenser to safely and efficiently disperse root retarding material to protect buried assets such as power lines, sewer lines, water pipes, telephone lines, fiber optic cables, DSL lines, cable lines, etc. from root damage.
Commercial and residential builders can use our novel material dispenser to safely and efficiently disperse root retarding material to protect newly constructed buried structures such as foundations, pipes, septic tanks, etc. from root damage.
Landscapers can use the material dispenser to safely and efficiently fertilize plants, and generate a recurring revenue stream by servicing and re-filling the dispensers.
The Problem Solved by the Technology
How the Technology Solves the Problem
A helical flange is secured to the shaft. The helical flange includes a single-lead thread having a root and a crest. The single-lead thread is wrapped around the shaft and has a hollow inner region between the root and the crest which is in communication with the hollow interior region of the shaft.
One or more openings are formed in the shaft or helical flange for dispersing the material or the liquid-material mixture into the ground. The shaft and helical flange are configured such that rotation of the shaft and flange causes the material dispensing device to be driven into the ground.
Various types of material can be safely dispensed into the ground using our novel device, such as fertilizers, root retarding compounds, etc.
Refillable, reusable and easy to maintain.
Unique design allows for optimal dispensing of material into the soil.
Helical shape combined with special device handle enables easy insertion into the soil.
Lid cover options provide for quick material filling and metering.
