Abstract
An apparatus for use in the transportation and production of cementitious mixes including a silo and a truck for transporting the silo. The silo is sub-divided internally into two compartments, one for cement and one for sand. At the lower end of the said compartment there is a vibratory grid and other structure for causing the sand to flow evenly from the open lower end of the silo into a mixer without bridging. A feed screw feeds cement from the cement compartment to the mixer. The truck has a lifting mechanism for lifting the vertical silo and tilting the silo through ninety degrees to a horizontal position for transportation purposes.
Claims6
An apparatus for containing binder and aggregate comprising:
- (a) a silo including a hollow body portion having a side wall, a top, a bottom and an internal partition dividing said body into a first compartment for containing a binder and a second compartment for containing aggregate;
- (b) a vibratory screen disposed proximate the bottom of said second compartment, said vibratory screen including a plurality of generally horizontally extending, horizontally spaced screen bars extending across the interior of said silo;
- (c) support means carried within said silo for supporting said screen bars, said support means comprising ledges formed around the inner periphery of said second compartment proximate the bottom thereof;
- and
- (d) vibrating means disposed exteriorly of said hollow body portion for imparting vibratory forces to said screen bars at regions thereof intermediate their ends.
A batching system comprising:
- (a) a silo for containing binder and aggregate comprising:
- (i) a silo including a hollow body portion having a side wall, a top, a bottom and an internal partition dividing said body into a first compartment for containing a binder and a second compartment for containing aggregate;
- and
- (ii) a vibratory screen disposed proximate the bottom of said second compartment, said vibratory screen including a plurality of generally horizontally extending horizontally spaced screen bars extending across the interior of said silo;
- (c) support means carried within said silo for supporting said screen bars, said support means comprising ledges formed around the inner periphery of said second compartment proximate the bottom thereof;
- and
- (d) vibrating means for imparting vibratory forces to said screen bars a regions thereof intermediate their ends;
- and;
- (e) a truck for lifting and transporting said silo including a chassis and lifting means for lifting said silo, said lifting means comprising:
- (i) a main frame pivotally mounted on said chassis for swinging movement about a transverse horizontal axis;
- (ii) a sub-frame carried by, and telescopic with respect to, said main frame;
- (iii) swinging means carried by said chassis for swinging said main frame and said sub-frame about said transverse horizontal axis between a horizontal position in which said frames overlie said chassis and an upright position in which said frames are disposed rearwardly of said chassis;
- (iv) displacing means for displacing said sub-frame vertically with respect to said main frame while said main frame is in its upright position;
- and
- (v) two silo engaging formations carried by said sub-frame, said formations being vertically spaced while sub-frame is upright, said formations serving to engage with and locate said silo both while said sub-frame is being moved vertically with respect to the main frame and while said sub-frame and main frame are being displaced about said axis.
