Abstract

A machine for coloring landscaping material is defined as having first and second mining chamber segments in which liquid colorant is introduced into the first segment in the form of a liquid spray and into the second segment in the form of an aerosol. Paddles supported by arms secured to a rotating shaft are provided through the first and second segments to mix and convey the landscaping material during coloring. Increased tip speed of the paddles is provided by relatively longer arms in the second segment to enhance interaction between the landscaping material and the aerosol colorant.

Claims (16)

1. An apparatus for coloring granular or particulate landscaping material comprising:
a mixing chamber including first and second elongated segments each defining an internal cavity, the internal cavity of said second segment communicating with the internal cavity of said first segment for passage of said landscaping material from said first segment to said second segment;
a colorant distribution system for delivery of a liquid colorant, said distribution system having first and second portions, said first portion extending into the internal cavity of said first segment and delivering the liquid colorant in the form of a liquid spray, said second portion extending into the internal cavity of said second segment and having an atomizer system for delivery of the liquid colorant in the form of an aerosol; and a material handling system extending through the internal cavities of said first and second segments for mixing of said colorant and said landscaping material within said mixing chamber and for conveying of said landscaping material through said mixing chamber.
2. The apparatus according to claim 1, wherein the first portion of said colorant distribution system includes at least one elongated pipe extending in the internal cavity of said first segment and having openings at spaced apart locations along a length of said pipe.
3. The apparatus according to claim 1, wherein the atomizer system of said second portion includes an atomizer nozzle at each of spaced apart locations along a length of said second segment.
4. The apparatus according to claim 3 further including an elongated dispersing chamber having an internal cavity communicating with the internal cavity of said second segment and wherein said atomizer nozzles are operably secured to a side of said dispersing chamber opposite said second segment.
5. The apparatus according to claim 1 wherein said material handling system includes at least one paddle in each of the first and second segments of said mixing chamber, each of said paddles operably supported by said material handling system for rotation about an axis.
6. The apparatus according to claim 5, wherein the at least one paddle of said second segment has a tip speed which is larger than a tip speed of the at least one paddle of said first segment.
7. The apparatus according to claim 6 wherein said material handling system includes a rotatably supported shaft extending through the first and second segments of said mixing chamber, and wherein each of said paddles is supported by an arm extending from said shaft and having a length such that the length of the arms located in said second segment is greater than the length of the arms located in said first segment.
8. The apparatus according to claim 5, wherein said paddles include forward and reverse paddles to facilitate mixing, said forward paddles having a face surface angled with respect to said shaft to impart an axial component of movement to said landscaping material in a downstream direction with respect to said mixing chamber and said reverse paddles having a face surface angled with respect to said shaft to impart an axial component of movement to said landscaping material in an upstream direction with respect to said mixing chamber.
9. The apparatus according to claim 1 further including a flow controller between said first and second segments, said flow controller extending transversely with respect to an elongated length of said second segment.
10. The apparatus according to claim 9, wherein said flow controller extends across an upper portion of the internal cavity of said second segment for directing said landscaping material from said first segment to said second segment at a lower portion of said second segment.
11. The apparatus according to claim 10 further including a second flow controller which extends into the internal cavity of said second segment transversely with respect to the elongated length of said second segment, said second flow controller extending across a lower portion of said second segment for directing said landscaping material in an upper portion of said second segment.
12. The apparatus according to claim 8 wherein said material handling system includes single arm locations and double arm locations in which a single arm location has one arm extending from said shaft at that location and a double arm location has arms extending from said shaft in each of two opposing directions at that location.
13. The apparatus according to claim 12 wherein said material handling system includes double arm locations within said second segment in which one of said arms supports a forward paddle and the opposite of said arms supports a reverse paddle.
14. The apparatus according to claim 7 wherein said material handling system includes a drive system secured to an end of said shaft for rotatably driving said shaft and wherein said material handling system further includes a hopper having an internal cavity communicating with the internal cavity of said first segment for introducing landscaping material to be colored by said apparatus into the internal cavity of first segment.
15. The apparatus according to claim 14 further including a material sensor extending into the internal cavity of said hopper at a height above said first segment for generating a system start signal when a level of said landscaping material within said hopper extends at least to the height of said sensor.
16. The apparatus according to claim 15 further including a control unit operably connected to either one or both of said material handling system and said colorant distribution system, said control unit further connected to said material sensor for start up of one or both of said material handling system and said colorant distribution system following receipt of said system start signal from said material sensor.
