Description
SPECIFICATION
Concrete mixing device employing the batch system
The present invention relates to a concrete mixing device employing the batch system.
Since the conventional concrete mixing devices are constructed in such a way that the concrete mixer is fixed on a stationary frame installed on the ground and an inclined conveyor is provided to supply aggregate to the mixer, such devices tend to be large in size and require considerable space.
Moreover, such devices cannot be transported and installed simply, factors which are drawbacks of such conventional mixing devices.
The object of this invention is a concrete mixing device that is small in size and capable of being simply transported. This concrete mixer can be moved up and down vertically and back and forth horizontally on its base by hydraulic means. A bucket for charging raw material which pivots vertically is attached to the outer part of the device base. Materials such as aggregates are supplied to the mixer by means of the bucket thereby eliminating the above-mentioned drawbacks of conventional concrete mixing devices.
The present invention is described below using the accompanying drawings which illustrate, by way of examples, the apparatus related to the present invention and in which: Figure 1 is a schematic plan view showing an embodiment of this invention viewed from above;
Figure 2 is a side view where the moving support platform and the concrete mixer have been lowered; and
Figure 3 is a view showing the support platform and the concrete mixer raised up hydraulically.
In Figures 1 through 3, reference numeral 1 denotes the base. The moving platform 2 is located above device base 1, and the upper ends of each set of hydraulically driven iifting members 3 are fixed to platform 2. The two members are joined where they cross and their lower ends are joined to pistons 4a of a pair of right and left cylinder mechanisms 4 fixed to the base 1. The lower end of telescoping support 5 is fixed to base 1, and the upper end portion of this support is fixed to movable platform 2.
The concrete mixer 6 is installed on the platform 2 and is able to move back and forth horizontally to the right and left. The mixer 6 is connected by means of lever 8 to piston 7a of a second hydraulic cylinder drive mechanism 7 fixed to platform base 2. A fresh concrete outlet 9 is provided at the lower part of one side of the mixer 6, and a cover 10 for opening/closing the outlet 9 is connected to a third hydraulic cylinder drive mechanism 11. Also, a water tank 12 for supplying water to the mixer 6 is fixed to the mixer 6, and a feed inlet 13 to be used for supplying cement to the mixer 6 is connected to the mixer 6.
In the Figure 1, 14 denotes the impeller blades of the mixer 6; numeral 1 5 denotes a motor for driving the impeller 14, and numeral 1 6 denotes a weighting device. The bucket rests on the its base in a horizontal position at one side of base 1. It can be moved right and left by a proper means (not shown) such as a hydraulic cylinder mechanism.
The tip of the bucket 1 8 is attached to an upright member 1 7a attached to the bucket base 1 7 so that the bucket can be pivoted into a vertical direction, and the bucket 1 8 is connected to a piston 1 9a of a fourth cylinder mechanism 1 9 fixed to the bucket base 1 7. The bucket 1 8 is constructed in such a way that the tip portion is positioned above a hopper 20 attached to the mixer 6 when the bucket is pivoted upward, and the main portion of the bucket touches the base when the bucket is lowered. The first to fourth cylinder mechanisms 4, 7, 11, and 20 are hydraulic cylinder mechanisms.
Next, the use of the concrete mixing device having the foregoing embodiment will be described. First, the entire mixing device of this embodiment is mounted on a truck and hauled to a concrete pouring location where it is unloaded from the truck, and the base 1 is placed in position on the ground. In this case, since the set-up work requires almost no special preparation of a hard base on the ground on which to place the mixing equipment, the work is easy and one day is sufficient for completion of the work. As shown in
Figure 2, the platform 2 is positioned at a suitable distance from the bucket base 1 7 so that it rests on base 1 so that the platform support base 2 and the bucket base 17 are positioned on base 1.In this arrangement, bucket 1 8 can be pivoted upward as shown by the dotted chain lines in
Figure 2 by causing the fourth cylinder mechanism 1 9 to operate and the piston 1 9a to expand, and the aggregate which has been measured and is in bucket 1 8 is supplied to the mixer 6 by means of the hopper 20, a measured portion of the water in tank 12 is supplied to the mixer 6 from water tank 12, and the cement from supply line 13 is supplied to the mixer 6. The impeller 14 is rotated by the motor 15, and the raw materials such as the water, cement and aggregate are mixed and kneaded. Before this mixing cycle is over, the fourth cylinder mechanism 1 9 causes the bucket 1 8 to return to a horizontal position.The first cylinder mechanism 4 causes the piston 4a to retract, and the lifting members 3 are caused to rise so that the mixer 6 is lifted to a desired height together with the support platform 2 as shown in
Figure 3. Upon completion of the mixing of the raw materials, the second cylinder mechanism 7 causes the piston 7a to horizontally shift the mixer 6 relative to the support base 2 as shown by the dotted lines of Figure 3, and the concrete outlet 9 of the mixer 6 is caused to project from one side of the support base 2.In this condition, a fresh cement carrier is brought beneath outlet 9 and the concrete mixed in the mixer 6 is supplied to the conveyance device (not shown) from outlet 9 by opening cover 10 by operation of the third cylinder mechanism 11. After the conveyance is filled, the third cylinder mechanism 11 closes the cover 10 of the outlet 9. At the time the support platform carrying the mixer 6 mentioned in the foregoing is raised, the height of the outlet 9 is changed according to a height of the conveyance vehicle that receives the supply of fresh concrete.After bucket 1 8 is returned to a horizontal position, the bucket base 1 7 is shifted to the aggregate storage area by being caused to move from the base 1, and the aggregate is loaded into the bucket 1 8 by using such means such as a shovel and the like.
Then, the bucket 1 7 is caused to move back to the position shown in Figure 2. After the bucket base 1 7 has moved, the ejection cycle of the mixed concrete from the mixer 6 is completed, and the cover 10 of the outlet 9 is closed. Thereafter, the mixer 6 is caused to return to its original position by the second cylinder mechanism 7, and the support platform 2 and the mixer 6 are caused to descend by the first cylinder mechanism 4, and returned to the condition shown in Figure 2 after which the foregoing cycle is repeated.
The concrete mixing device of this embodiment employs an NC control system which results in decreased error in measuring of raw materials, and also, a detachable operator's seat can be installed at a proper location.
The mixer 6 of this invention as such may be of any proper type, but it is preferable to use the forced mixing type as per the embodiment since homogeneous concrete can be rapidly made. The bucket of this invention may be of any proper type as long as it pivots in a vertical direction by means of the hydraulic cylinder mechanism, and the charging means of the aggregate and the like to the bucket may be changed optionally depending on the location of the aggregate.
As described in the foregoing, the concrete mixing device of this invention is constructed in such a way that the platform can be raised above the base by the hydraulic cylinder mechanism, and the concrete mixer is provided with a concrete outlet at one side of the lower portion so that it can be positioned horizontally by the other hydraulic mechanism, and the bucket that pivots in a vertical direction by means of another hydraulic cylinder mechanism is located at the outer end of the base so as to be able to charge the raw materials into the mixer such that no stationary frame for an inclined conveyor is required as per the conventional type concrete mixing apparatus so that the concrete mixing device of this invention is of small size and can be simply shifted and set up easily in a small space, and can be easily removed as a result of which work site space can be effectively utilized, and when raw materials such as the aggregate and the like are fed into the bucket, the support base provided with the mixer is lowered so that a mechanism for not only pivoting the bucket in a vertical direction but also supplying raw materials such as the aggregate and the like to the mixer is of simple construction, and moreover, major component parts are available from commonly available component parts which enable easy repair as well as replacement. Likewise, since the major operations are carried out by hydraulic cylinder mechanism, problems seldom occur and reliable operations can be expected because of the device of invention.
