Title: FRAMELESS MIXING BIN
Field of Invention _ .
This invention relates to a mixing bin of the type in which rotating paddles agitate a substance which is to be mixed. More particularly, it relates to the support means ror such a bin and its adaptation as a mobile and stationary batch plant cement mixer.
Background to the Invention In the prior construction of mixing bins of the agitating paddle type, bins have been constructed with bottom surfaces of circular cross-section. The circular shape of this bottom surface co-operates wi-th an internal rotating paddle system to optimize mixing efficiency. Prior patents describing such a structure include Canadian Patent No.
1,124,709 and ~nited States Patent No. 4,157,872.
In bins of such configuration, reliance has been placed on the metal of the bin wall-itself to provide longitudinal rigidity to the bin. It has been customary, on occasion, to support such bins with a series of trans-verse, cradle-plates. Such plates engage the curved lower surface of the bin along the upper edgesof the plates and rest upon an outer steel frame on their lower edges. In such an arrangement, the frame must be of sufficient stiffness to carry the point-loads applied by the cradle-plates. This problem is of particular concern in the case of a mobile cement mixer of the type described in the above referenced patents, where a load of pre-mixed concrete ~2~42al6 is delivered in the bin to the work sl-te. In such applications the force transmitted through the frame to the wheels will include not onIy the weight of the fully loaded vehicle, but also the inertia loads associated with transporting the pre-mix over uneven road surfaces. The incorporation of a frame of adequate stiffness to sustain these loads may incur weight penalties in accordance with th~e amount of steel used.
:
Objects of the Invention Accordingly; lt is one object of this invention to provide a means of support for a mixing bin whlch does not entail the construction of a separate frame.
A further object of the invention is to provide a support means for a mixing bin which may be adapted to be mounted on wheels wlthout the inclusion of a separate frame.
A further object of the invention is to provide a~ ;
~support structure for~a mixlng bin~which, by reason of lts~
specific form may be simultaneously adapted to transport fluids and, in particular, fluids under pressure. ;
Summary of the Invention A support structure is provided for a mixing bin having a cylindrical lower surface which comprises:~

Brief Summary of the Drawings Figure 1 is a perspective view of a mobile mixing bin adapted for transport and delivery of pre-mixed concrete;
Figure 2 is an end view of the aforesaid mobile mixer wi-thout the motor and transmission system installed;
Figure 3 is a perspective of the two box beams 12242~
_ 4 as mounted on the bin, one box beam being adapted to serve as a pressuri~ed reservoir for water and the other as a reservoir for hydraulic fluid, and Figure 4 is a cross-sectional view through the beams depicted in Figure 3.
Description of the Preferred Embodiment The mixing bin 1 as shown in Figure 1 is mounted on a pair of tandem wheels 2. The bin 1 has two end walls 3a, b within which the mixing paddle shaft 4 is journalled.
The sidewalls of the bin 1 have a flat vertical portion 5 and a cylindrical curved lower portion 6 best seen in Figure 2. This shape need not necessarily be perfectly circular in cross-section but need only be cylindrical in the broader sense of the meaning of the word, subject to obtaining adequate efficiency of mixing from the paddle system. Along the sides of bin 1 against this curved portion 6 runs the two box beams 7a, b that support the bin 1. A gasoline motor 32 drives a hydraulic pump 33 and motor 34 which activates the mixing paddle shaft 4.
As shown in Figure 2, beneath the bin 1 passes a tension plate 8 which passes between and is welded to the inner lower panels of the respective box beams 7a, b at its outermost ends. In fact, three such plates are equally spaced beneath the bin 1, but only one is shown.
This tension plate 8 is curved along its upper edge 9 to follow and lie against the lower curved surface 6 of the bin 1. In this way the tension plate 8 ~22~2(~E;
may receive part of the weight of the bin 1 and its contents and then transfer such weight to the box beams 7a, b. The weight being so absorbed does not, however, comprise the greater part of the weight of the bin 1 since the box beams 7a, b support the bin directly. The tension plate may be optionally welded along its upper edge 9 to attach it to the curved lower surface 6 of the bin 1. Such weld-ing will permit the tension plate 8 to serve to maintain the curvature of the lower portion 6 of the bin 1.
Additionally shown ln Figure 2 are shackles lOa, b, by which springs ll are attached to the lower panels of the box beams 7a, b. An axle 12 is mounted to such springs 11, with wheels 2 carried at the outer ends of the axle.
The two box beams 7a, b which are of similar outer bat differ1ng 1nternal form, are shown in greater detail in the perspective~view, Figure 3. Each are ;~

The two box beams 7a, b which are of similar outer bat differ1ng 1nternal form, are shown in greater detail in the perspective~view, Figure 3. Each are ;~
adapted to different~applications.
The box beam~ 7a in Plgure~3 lS lnte~nded to serve as a pressurized container for water. The water to be con~
tained therein will be used to mix with cement and to wash :
down the bin 1 after discharge of a load of concrete.;~ The box beam 7b in Figuxe 3 is adapted to serve as a reservoir for hydraulic fluld where hydraulic systems are used to~
activate the mixing action.
The expression box beam as used herein is intended to refer to a hollow tubular beam of closed, but not necessarily rectangular cross-section. In the preferred embodiment depicted in Figure 3 this beam is composed of '
3 ZZ4~6 five flat longitudinal panels 13. The panels form the outs1de walls of the box beam 7a and are joined along their edges to adjacent panelsby means of welded seams.
All of the sheet and plate materials described herein with respect to the preferred embodiment are made of steel. Other suitable materials such as copper, brass or plastic may be substituted therefore, subject to selection of gauges and thicknesses appropriate to absorb the loads intended to be imposed. In such cases appropri-ate techniques for forming seams, such as brazing for brass or copper, or radio-welding for plastic would be applied. The structure described herein is adapted to the use of CHT-100 sheet steel of 3/16 inch thickness in the bin wall, for a bin designed to transport and mix 1 1/2 at 1 3/4 cubic yards of pre-mixed concrete.
The box beam 7b in Figures 3 and 4 is not intended to be pressurized since it serves as a reservolr for hydrauIic fluid which is independently pumped. It is~
formed of five flat-external longitudinal panels 14, two which are welded directly to the lower surface 6 of the bin 1 It also contains one longitudinal internal panel 14a.
The innermost external longitudinal panel 14b may option-ally be omitted, in which case a portion of the lower bin wall 6 closes off the beam structure and participates as one of the panels of the box beam, so formed.
In the case of both beams 7a, b, transverse bulkhead plates or baffles 15, 21 are disposed within the tubular core of the beams to give the beams dimensional ~L22~
, stability. Such bulkheads are shown in dotted outline in Figure 3. ~oth bulkheads 15 and 21 may also be seen in the cross-sectional view shown in Figure 4. In Figure 4 the longitudinal panels 13, 14 of each box beamform a polygonal outline in cross-section, with one inner panel 13b, 14b in each beam destined to be juxtaposed adjacent the lower portion 6 of the bin 1.
The beams 7a, 7b are attached to the lower por-tion 6 of the bin 1 along extensions 18 to the longitudinal edges of the two plates 13, 14 which pass by and are welded to the edges of the inner plates 13b, 14b.
The bulkhead panels 15, 21 within the beam 7a, 7b are not necessarily formed of solid sheets, but may have holes, such as the hole 19 in Figure 4, formed the~ein to reduce weight. The size and placement of such holes should always be chosen subject to the objective of maintainlng adequate strength. When the box beams 7a, b are~also intended to serve as storage compartments for fluids, the end bulkhead panels 15a will, of course, be solid and unperforated except to provide outlets by way of taps or hose aouplings 20.
Further, notches 22 may be formed along the upper and lower edges of the interior bulkhead plates 15, 21 to permit passage of fluid between the chambers defined by such bulkheads. Alternately, holes (not shown) may be drilled in close proximity to the lower edges of such plates in order to provide the same function.
In the case of the beam 7b as shown in Figure 4, ,, --` lZ~
the two equally spaced interior bulkhead plates 21 (only one of which is shown in cutaway outline in Figure 4) occupy only a lower portion of the cross-sectional area within the beam, beingconnected between only three of the longi-tudinal panels 13. In the box beam 7b, the internal longitudinal plate 14a lies along the upper edges of the baffles 21, forming a horizontal baffle. This internal longitudinal plate 14a~as depicted in Figure 3 does not extend the entire length of the box beam 7b, terminating at an edge 26. The open volume created by termination 26 of the interior longltudlnal plate 14a short of~ the entire length of the box beam 7b serves to provide communication between the upper and lower regions within the beam. A
further opening 28, of rectangular form in the preferred embodiment, may be created within this reinforcing plate ~ ~ :
at the opposite end to provide additional communication~
between the upper and~lower regions~in the beam and provld~e access-to a filter or strainer mounted thereln-.
The triangular cross-section~provided by the - ~
panels 14, 14a and 14b form a tubular box beam element by ~ ;
themselves which is dimensionally ridged without provislon of internal bulkheads such as bulkheads 15 or 21. Where ;
the box beams are built up entirely of similar dimension-ally stable elements with triangular cross-sections, the bulkheads, while desirable, are not essential.
In order to clear fluid and debris that ~ay have accumulated within the beams 7a, b, a drain hole with plug 24 may be formed within the lower or bottom most of the - .

longitudinal panels 13, 14. In order to produce a pressur-ized flow of water from the beam 7a, one of the hose couplings 20a may be used to insert pressurized air into the chamber formed inside the beam 7a through an air tight valve 35 (shown in Figure 1) which is provided to retain the pressurized air in the tank oncè the beam chamber has been charged. Water may be added to the tank by removing an air tight filler cap 33.
At the~ends of the pressurizable beam 7a the longitudinal panels 13 extend past the last solid bulkhead 15 by several inches. This extension serves to protect tube couplings 20. A short longitudinal bracing plate 25 as shown in Figure 3 may be placed within this extended region, angled so as to pass from the upper outermost seam of the longitudinal panels 13 down to terminate along the face of a lower opposed longitudinal plate 13 to create - :
two trapezoidal regions in cross-section and provide additional rigidity. ~ - ~
~`
Mounted along the upper outer panel of the beam 7b is an access box 29 with a lid 30. A breather cap 31 is mounted on the lid to provide free passage of air into or out of the beam 7b. A filter basket or strainer (not shown) may be placed beneath the rectangular opening 28 and connected to the hydraulic fluid outlet 20b. A
hydraulic fluid return inlet 3~l is also provided.
In the foregoing disclosure, a detailed description has been provided of two types of box beams, both of which are adapted to c~rry fluid. While the - 122~ 6 ability to carry fluids is of considerable convenience on a vehicle of this type, the fact that one of the storage systems may be pressurized is particularly advantageous. This is so because it is especially important to wash down the mixing bin after use and a pressurized jet of water is ideal for this purpose.
The foregoing is a description of the preferred embodiment of the invention. The scope of the invention is defined by the claims now set forth below.
All of the sheet and plate materials described herein with respect to the preferred embodiment are made of steel. Other suitable materials such as copper, brass or plastic may be substituted therefore, subject to selection of gauges and thicknesses appropriate to absorb the loads intended to be imposed. In such cases appropri-ate techniques for forming seams, such as brazing for brass or copper, or radio-welding for plastic would be applied. The structure described herein is adapted to the use of CHT-100 sheet steel of 3/16 inch thickness in the bin wall, for a bin designed to transport and mix 1 1/2 at 1 3/4 cubic yards of pre-mixed concrete.
The box beam 7b in Figures 3 and 4 is not intended to be pressurized since it serves as a reservolr for hydrauIic fluid which is independently pumped. It is~
formed of five flat-external longitudinal panels 14, two which are welded directly to the lower surface 6 of the bin 1 It also contains one longitudinal internal panel 14a.
The innermost external longitudinal panel 14b may option-ally be omitted, in which case a portion of the lower bin wall 6 closes off the beam structure and participates as one of the panels of the box beam, so formed.
In the case of both beams 7a, b, transverse bulkhead plates or baffles 15, 21 are disposed within the tubular core of the beams to give the beams dimensional ~L22~
, stability. Such bulkheads are shown in dotted outline in Figure 3. ~oth bulkheads 15 and 21 may also be seen in the cross-sectional view shown in Figure 4. In Figure 4 the longitudinal panels 13, 14 of each box beamform a polygonal outline in cross-section, with one inner panel 13b, 14b in each beam destined to be juxtaposed adjacent the lower portion 6 of the bin 1.
The beams 7a, 7b are attached to the lower por-tion 6 of the bin 1 along extensions 18 to the longitudinal edges of the two plates 13, 14 which pass by and are welded to the edges of the inner plates 13b, 14b.
The bulkhead panels 15, 21 within the beam 7a, 7b are not necessarily formed of solid sheets, but may have holes, such as the hole 19 in Figure 4, formed the~ein to reduce weight. The size and placement of such holes should always be chosen subject to the objective of maintainlng adequate strength. When the box beams 7a, b are~also intended to serve as storage compartments for fluids, the end bulkhead panels 15a will, of course, be solid and unperforated except to provide outlets by way of taps or hose aouplings 20.
Further, notches 22 may be formed along the upper and lower edges of the interior bulkhead plates 15, 21 to permit passage of fluid between the chambers defined by such bulkheads. Alternately, holes (not shown) may be drilled in close proximity to the lower edges of such plates in order to provide the same function.
In the case of the beam 7b as shown in Figure 4, ,, --` lZ~
the two equally spaced interior bulkhead plates 21 (only one of which is shown in cutaway outline in Figure 4) occupy only a lower portion of the cross-sectional area within the beam, beingconnected between only three of the longi-tudinal panels 13. In the box beam 7b, the internal longitudinal plate 14a lies along the upper edges of the baffles 21, forming a horizontal baffle. This internal longitudinal plate 14a~as depicted in Figure 3 does not extend the entire length of the box beam 7b, terminating at an edge 26. The open volume created by termination 26 of the interior longltudlnal plate 14a short of~ the entire length of the box beam 7b serves to provide communication between the upper and lower regions within the beam. A
further opening 28, of rectangular form in the preferred embodiment, may be created within this reinforcing plate ~ ~ :
at the opposite end to provide additional communication~
between the upper and~lower regions~in the beam and provld~e access-to a filter or strainer mounted thereln-.
The triangular cross-section~provided by the - ~
panels 14, 14a and 14b form a tubular box beam element by ~ ;
themselves which is dimensionally ridged without provislon of internal bulkheads such as bulkheads 15 or 21. Where ;
the box beams are built up entirely of similar dimension-ally stable elements with triangular cross-sections, the bulkheads, while desirable, are not essential.
In order to clear fluid and debris that ~ay have accumulated within the beams 7a, b, a drain hole with plug 24 may be formed within the lower or bottom most of the - .
' ' ' ~ `:
:
longitudinal panels 13, 14. In order to produce a pressur-ized flow of water from the beam 7a, one of the hose couplings 20a may be used to insert pressurized air into the chamber formed inside the beam 7a through an air tight valve 35 (shown in Figure 1) which is provided to retain the pressurized air in the tank oncè the beam chamber has been charged. Water may be added to the tank by removing an air tight filler cap 33.
At the~ends of the pressurizable beam 7a the longitudinal panels 13 extend past the last solid bulkhead 15 by several inches. This extension serves to protect tube couplings 20. A short longitudinal bracing plate 25 as shown in Figure 3 may be placed within this extended region, angled so as to pass from the upper outermost seam of the longitudinal panels 13 down to terminate along the face of a lower opposed longitudinal plate 13 to create - :
two trapezoidal regions in cross-section and provide additional rigidity. ~ - ~
~`
Mounted along the upper outer panel of the beam 7b is an access box 29 with a lid 30. A breather cap 31 is mounted on the lid to provide free passage of air into or out of the beam 7b. A filter basket or strainer (not shown) may be placed beneath the rectangular opening 28 and connected to the hydraulic fluid outlet 20b. A
hydraulic fluid return inlet 3~l is also provided.
In the foregoing disclosure, a detailed description has been provided of two types of box beams, both of which are adapted to c~rry fluid. While the - 122~ 6 ability to carry fluids is of considerable convenience on a vehicle of this type, the fact that one of the storage systems may be pressurized is particularly advantageous. This is so because it is especially important to wash down the mixing bin after use and a pressurized jet of water is ideal for this purpose.
The foregoing is a description of the preferred embodiment of the invention. The scope of the invention is defined by the claims now set forth below.
