Description
i~Z4~09 This invention relates to a vehicle adapted for delivery of ready mix concrete mixtures, more particularly of the type suitable for small quantities and driven to the site by the buyer himself.
There is presently in use a vehicle of the above type in the form of a trailer that is hitched to the buyer's car or the like vehicle to be driven wherever wanted. In that concrete mixture delivery vehicle, there is no agitation of the concrete mixture during its transportation and thus the concrete cannot be prevented from setting if it stays longer than expected in the trailer.
There hav~ been proposed concrete mixers that are suitable for the delivery of concrete mixtures as above mentioned. For instance, Canadian Patent No. 293,202 issued September 17, 1929 in the name of W.M. Walker et al discloses such concrete mixer delivery vehicle and ~.S. Patent No.
4,043,540 issued in the name of discloses a concrete mixer that could be used on a trailer. In both of these patented concrete mixers~ the tank holding the concrete mixture must be tilted to unload the concrete mixture. This is difficult to do by hand at least for some potential customers due to the weight involved that has to be controlled to properly unload. If, as suggested in the Canadian patent, an elevating means is used to tilt the tank, there results more complexity, weight, and higher costs.
It is a general object of the present invention to provide an improved concrete mixer and delivery vehicle of the above type that is adapted to agitate the mixture during its transportation.
It is a more specific object of the present invention to provide an improved concrete mixer and delivery vehicle ~ 'r ~, 1~24709 of the above type that is provided with a paddle assembly which is taken advantage of to produce agitation and more particularly to also produce effortless unloading of the concrete mixture.
It is another object of the present invention to provide an improved concrete mixer and delivery vehicle of the above type that is provided with a paddle assembly of improved construc-tion and opera-tion and in particular that moves the concrete mixture in the tank in both directions in a closed circuit back and,forth along the tank thus providing more thorough mixture and preventing more accumulation at one end and excessive reactions on the paddle blades at that end.
It is a further object of the present invention to provide an improved concrete mixer and delivery vehicle of the above type that is provided with a paddle assembly with its paddle blades longitudinally spaced and arranged along the tank to wipe against all the inner bottom surface of the tank to unload the tank clean over all its bottom ~20 surface.
In accordance with the invention, the concre-te mixer and delivery vehicle of the above type i9 improved in that:
a) at least one end of the shaft of the paddle assembly is connected with frangible pins to a stub shaft extending at one end of the vehicle to allow shearing of the pins whenever too much resistance to rotation is encountered by the paddle assembly;
b) each paddle comprises a radial arm rigidly secured to at one and of the assembly shaft, an outermost blade adjustably secured to other end of the arm, and another blade also secured to the radial arm intermediate ~124~09 the ends thereof, and c) the radially outermost blades complementarilyextend over substantially the full axial length of the cylindrical bottom portion to wipe substantially the entire surface of the latter.
The outermost blades are wipingly moving against the cylindrical bottom portion of the tank upon rotation of the paddle assemblv and are angularly set relative to the axial direction of the paddle assembly for axial moving of the concrete mixture in either axial direction upon rotation of the paddle assembly. The other blades, are angularly set crosswise relative to the radially outermost blades whereby to move the concrete mixture in opposite axial direction relative to the radially outermost blade upon rotation of the paddle assembly.
The above and other objects and advantages of the present invention will be better understood with reference to the following detailed description of a preferred embodiment thereof which is illustrated, by way of example, in the accompanying drawings; in which:
Figure 1 is a perspective view of a concrete mixer ' delivery vehicle according to a preferred embodiment of the present invention;

- 3 b -1~24709 The illustrated concrete mixar delivery vshicle takes the fnrm of a trailer adapted to be pulled by one's car or motor vehicle after purchase of the load of concrete mixture at a store that sells such servica. The concrete mixer deli~ery vehicle includes a sturdy trailer frame 1, of convantional construction and conventionally mounted on a pair of wheel axles and appropriate springs, as shown. A
conventional hitch mechanism 2 allows to hitch the trailer to a motor vshicle to be driuen to the site where the concrete will be poured.
A tank 3 for the concrete mixture i8 fixedly mounted or secured on arch-shaped br~ckets 4 of the frame 1. The tank 3 comprises a cylindrical bottom 5, opposite end walls 6 and 7, a top loading opening ~ and laterally opposite side walls 9, 9. A safety screen 10 is removably secured in top opening ~ to load the concrete nixture into the tank 3. The loading top opening is nearly coextensive in width end lefigth with the tank 3 to readily remove the hereinafter described paddle assambly through it. An unloading rear door 11, of any ap-propriate detail construction and operation, is provided in the rear end wall 7 adjacent the bottom of the tank to completely unload the latter.
A pair of stub shafts 12 and 13 are rotatively secured to the end walls 6 and 7 and inwardly project a predetermined distance toward each other coaxially with the axis defined by the cylindrical bottom 5. ~ paddle asssmbly is removably engaged on the stub shafts 12, 13 to bodily rotate with them. The paddle assembly comprises a tubular shaft 14 which i9 of predetermined length to tubularly engage onto the inner end of the stub shafts 12, 13. Frangible pinQ 15, or the like, connect at least the forward end of the tubular shaft 14 on the forward stub shaft 12 to allow shearing of the pins whenever too much resistance to rotation i8 encountered by the paddls assembly. The length of the tubular shaft 14 is chosen in relation with the axial length of the . tank 3 and the length of the stub axles 12, 13 to allow installation and removal of the tubular shaft relative to its operativs tubular ~ 1 24709 engagement on both stub shafts 12, 13. After removal o~ safety screen 10, top loading opening 8 allows insertion and remoua] of the paddle assembly in and ~rom the tank 3. The paddle assembly also includes radial arms 16 that are rigidly secured at one end to the tubular shaft`
14 and which radially extand endwise from the latter in diametrically-opposite directions and in axially spaced-apart relationship along the tuhular shaft.
Each radial arm 16 is provided with a blade assembly including a radially outermost blade 17 and a blade la intermediate the ends of the radial arm. The outermost blades 17 are each formed with a rubber strlp 19 ~andwiched batween rigid faces 20 and arranged for radial adjustment to effectively scrape against the cylindrical inner surface of the cylindrical bottom S of the tank. All of the blades 17 longitudinally extend in the same angular direction relative to the axial direction snd the blades lB extsnd crosswise relative to the blades 17, as best shown in Figure 6, in another angular direction with respsct to the axial direction. Furthermore, the blades 17 longitudinally extend and are spaced apart such as to cooperatively cover the full length of ths cylindrical bottom and, thus, wipe against all the inner cyl-inderical surface thereof to clean it all. That cleaning is achieved through the angular direction ,of the blades 17 that causes the latter to axially move the concrete mixture and to unload it through the door 11 upon rotation of the paddle assembly in one particular direct~on. When the rotation is done in the opposite direction, the blades 17 push or move the concrete mixture toward the ~ront and the blades lB push the concrete mixture toward the rear. There is thus praduced a fore-and-aft circuit of displacement that is used to agitate the mixture during transportation and before its unloading through rotation in the opposite direction.
The afore-mentioned rotation is produced by an engine 21 driving the paddle assembly through a gearbox 22 and a chain 23, with means provided to reve'rse the direction of rotation. Chain 22 is protected by a cover 23'.
