Abstract

Cement storage apparatus comprises a tank (14) having an internal discharge auger (24) and an agitator (36). Manual rotation of the auger by means of a handle (100) discharges cement into a bucket (102) through a butterfly valve (90). The tank is filled through an opening (30) which is sealable. Dry cement powder within the tank is protected against the ingress of moisture and can be readily dispensed in small quantities by simple manual means whereby wastage of the cement powder is greatly reduced.

Description

SPECIFICATION Portable dry powder bowser.
This invention relates to a portable dry powder bowser.
Portable dry powder bowsers will be used for the transport of bulk dry powder materials, e.g. Ce- ment or plaster. Therefore the dry powder bowser will be referred to according to whichever material is being carried by the bowser at that time. If for instance, the dry powder bowser is carrying cement, it will be known as a cement bowser.
The amount or weight the bowser will carry depends on what size the bowser is. This will vary as it can be built in different sizes to accommodate the various desired weights.
The portable dry powder bowser is loaded by lifting an airtight manhole cover on top of the bowser, which is then screwed down to seal it when the bowser is loaded. It can then be towed to its destination where the bowser's adjustable legs will be let down to make it stable enabling the towing truck to be unhitched from the bowser.
Once the bowser is in position, the operator dispenses the material by first opening the discharge door and manually turning the handle at the discharge end of the bowser. By turning the handle this will turn the shaft which runs the length of the bowser tank attached to the shaft which is in a sealed holder. A continuous screw, or spaced paddles attached to the shaft, enables the material to be driven to the discharge outlet. When the operator has obtained the desired amount of powder, he stops turning the handle and closes the discharge door.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in perspective the tank and discharge screw paddle holder in position on the chassis; Figure 2 illustrates the separation of the tank from the screw paddle holder and chassis; Figure 3 illustrates the separation of the screw paddle holder from the tank and the chassis; and Figure 4 illustrates the separation of the chassis from the screw paddle holder and tank.
Referring to the drawing Figure 1, the bowser comprises a wheeled chassis 17, fixed tank supports 19, adjustable legs 18 and a body in the form of a tank 10, releasably secured to the chassis by adjustable steel straps 12 and a screw paddle holder 14, releasably secured to the tank by bolts as shown in Figure 2 and 3. In order to remove the tank 10 and screw paddle holder 14, steel straps 12 are released and the tank 10 is lifted off the chassis 17. To remove screw paddle holder 14 from the tank 10, unscrew connecting bolts.
In order to load bowser illustrated in Figure 1, open the airtight manhole door 11, Figure 2. There is an outlet 21 in the tank 10, thus allowing material to enter screw paddle holder 14.
In order to discharge material open door 16 turn handle 15.
As illustrated in Figure 3, the material is driven towards outlet opening 22 by spaced paddles or continuous screw which is fixed to the shaft 20 and handle 15. There is an inspection plate 13 above outlet door 16, Figure 1.
The bowser can be tilted by adjusting the legs 18 Figure 1, which also stabilizes the bowser.
1. A dry powder bowser comprising a wheeled chassis, a body in the form of a tank, a releasably connected air tight manhole cover, detachable screw or paddle holder, a hand operated handle to drive shaft, with attached paddles or continuous screw which is housed in the holder. At the handle end of the holder is an outlet and retaining door.
Above the door is an inspection plate. Means for releasably securing the body on the chassis and adjustable legs provided on the chassis at each corner and fixed supports to arrest movement.
2. A portable dry powder bowser as claimed in claim 1 wherein an airtight manhole door is connected to the body.
3. A portable dry powder bowser as claimed in claim 1 wherein a detachable screw or paddle holder is attached to the body.
4. A portable dry powder bowser as claimed in claim 1 or claim 3 wherein a handle is hand operated to drive a shaft with attached screw or paddles, which is housed in the screw paddle holder.
5. A portable dry powder bowser as claimed in claim 1 or claim 4 wherein a discharge door is attached to the discharge end of the screw or paddle holder and an inspection plate above the discharge outlet.
6. A portable dry powder bowser as claimed in claim 1 wherein the chassis has fixed supports to arrest movement and provided are adjustable legs on each corner to arrest tilt and stabilize the bowser.
7. A portable dry powder bowser substantially as described herein with reference to Figures 1 - 4 of the accompanying drawing.
