Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transporting concrete materials such as coarse aggregate, sand, cement, etc., and for kneading these materials in a vehicle. It is something.

In conventional concrete mixer trucks, the mixer drum is rotatably mounted on the chassis frame.
Concrete materials such as coarse aggregate, sand, cement, etc. and water are put into the mixer drum, and the concrete materials and water are mixed by the rotation of the mixer drum. It is known that a container is mounted on a tower, and the concrete material and water put into the container are kneaded by a stirring device. The concrete materials put into the container are mixed with water and kneaded in one motion to produce ready-mixed concrete, so in order to complete the mixing and obtain high-quality ready-mixed concrete, the mixing time must be set at a specified time. It is necessary to set the setting within a certain time, and therefore the transport speed of the mixer truck has to be unnecessarily slowed down or accelerated.Also, it is possible to use all the mixed mixed concrete within a specified time, but If the ready-mixed concrete is dispensed and used over a long period of time, the ready-mixed concrete may be insufficiently mixed or overmixed, making it unusable. There were some problems, such as the need to clean the concrete containers to ensure that no fresh concrete remained.

Therefore, in order to eliminate such drawbacks of the conventional method, the constituent materials of concrete are transported to the concrete placement site, and these materials and water are mixed together to produce the required amount of ready-mixed concrete. Various methods have been proposed to do this, but
All of these methods have various defects such as insufficient mixing of concrete, large and heavy equipment, complex structure, and are expensive, and are troublesome to operate, so they cannot be put to practical use. Nakatsuta.

In view of the above, the present invention has been developed to transport concrete materials such as coarse aggregate, sand, cement, etc. and water in a separated state to a concrete placement site, or to replenish them at the site, where water is continuously required. By thoroughly mixing concrete, it is possible to easily mix and produce fresh concrete with the optimum mix composition, and in particular, it is possible to mix reliably and homogeneously without coarse aggregate, sand, and cement coagulating together and creating unevenness. It is an object of the present invention to provide a device for conveying concrete materials in a vehicle and continuously kneading the same, which has a simple structure and is inexpensive.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. On the main frame 1 of the vehicle V, a box-shaped vessel 3 is mounted on a subframe 2 and can be tilted rearward around a pivot shaft 4 by a lift cylinder 5. It is listed as such. The intermediate portions of the left and right side walls of the Bethel 3 are each inclined inward. At the center of Bethel 3, a vertical partition wall 7 is erected on its longitudinal axis, and this vertical partition wall 7
Its front end is fixed to the front wall of the vessel 3, and its rear end is fixed to the horizontal partition wall 8 which is erected across the rear of the vessel 3, and its lower part is attached to the left and right loading walls, which will be described later. It is connected to side walls defining channels 12,13. The inside of the Bethel 3 is divided by the vertical partition wall 7 and the horizontal partition wall 8.
three chambers, namely left ventricle A, right ventricle B and posterior ventricle C
In this embodiment, the left chamber A stores coarse aggregate (gravel), the right chamber B stores sand, and the rear chamber C stores cement. At the upper front of each of the entry paths 12 and 13, there are provided walls 8a and 8b in the left and right direction, which are open at the bottom. Further, the upper surfaces of the left and right chambers A and B are open, and the upper surface of the rear chamber C is covered with a lid 11 having a manhole 10.

The floor plate 6 of the sand storage chamber B is inclined forward upward by about 5 degrees from the base end toward the tip in the direction in which the vessel 3 is tilted. A lightening plate 6a is installed.

Further, in the left ventricle A, partition walls 9, 9, . . . are fixedly installed in a direction substantially perpendicular to the floor surface 6 thereof. A space is formed below the partition wall 9 with an appropriate distance from the floor plate 6 of the left ventricle A, and the space extends upward to near the upper edge of the vessel 3. In this way, the left ventricle A is divided into chambers A ₁ , A ₂ , A _{3 .} . . as shown in the figure.

Immediately below the rear chamber C, left and right entry paths 12 and 13 are provided symmetrically to the left and right along the longitudinal direction of the vessel 3. In addition, as shown in the diagram, the loading path 1
The floor 6 of No. 2 is constructed lower than the floor 6 of the carry-in path 13. These left and right carry-in passages 12 and 13 communicate the left and right chambers A and B, respectively, with a conveying and mixing device 20, which will be described later. A stirring device, that is, a stirring wheel 15 is rotatably supported in the right carry-in path 13.
This stirring wheel 15 is connected to a hydraulic motor 18 via a known transmission means and is forced to rotate. In addition, in the right entry path 13, behind the stirring wheel 15,
A metering and feeding device, that is, a metering rotary feeder 17 is rotatably supported and coupled to a hydraulic motor 18 for forced rotation. On the other hand, in the left carry-in path 12, at almost the same front and back position as the feeder 17,
A metering feeder, ie a metering rotary feeder 16, is rotatably supported and driven in forced rotation by a hydraulic motor 19.

14 is a roller rotatably supported in the left carry-in path 12 and in front of the feeder 16.
The outer periphery of the roller 14 is made of an elastic material such as rubber. Furthermore, the roller 14 is pivotally supported by a sliding body 14a fitted in a space below the floor 6 so as to be movable in the front and back direction. Adjustment of the longitudinal position of the sliding body 14a is performed, for example, by a known screw means 14b. By adjusting the longitudinal position, the gap between the outer periphery of the roller 14 and the feeder 16 can be adjusted.

Therefore, when the agitation wheel 15 and quantitative rotary feeders 16 and 17 are rotated together, sand in particular among the coarse aggregate and sand stored in the left and right chambers A and B, respectively, is transferred to the agitation wheel 15 as will be described later. After being stirred by the metering rotary feeders 16 and 17, the metering is moved in the left and right loading paths 12 and 13 to the left and right conveying chambers 31 and 3 of the conveying and mixing device 20, which will be described later, respectively.
Sent to 2.

Furthermore, the proximal end of the elastic body 17b is fixed to the ceiling of the carry-in path 13 so that the tip 17c of the elastic body (steel plate) 17b is exposed between the blades 17a of the quantitative rotary feeder 17. (See Fig. 6.) Each blade of the quantitative rotary feeder 16 is inclined forward in the direction of travel with respect to the radial direction as shown in the figure (i.e., has a rake angle), and its outer edge is also beveled, ie each vane is formed in a spiral. This makes it possible to equalize the load applied to the blades of the feeder 16 by the coarse aggregate, and also to eliminate the clogging phenomenon caused by the coarse aggregate.

Further, in the lower part of the rear chamber C, a conveying stirring device, that is, left and right conveying cars 22a, 22b and a central stirring wheel 22c are configured on a common shaft and are rotatably suspended horizontally, and further below this stirring wheel 22c. A quantitative feeding device, that is, a quantitative rotary feeder 23 is horizontally suspended rotatably at the rear, and a discharge side opening 23a of the quantitative rotary feeder 23 is opened at the lower part of the rear wall of the vessel 3, and is further connected to the flexible chute 19. It is therefore extended. The transport vehicles 22a, 22b and the stirring vehicle 2
A hydraulic motor 25 is connected to 2c, and a constant rotation feeder 23 is also connected to this hydraulic motor 25 via a one-way clutch by known means (not shown), so that it is forced to rotate. , when they are rotated, the cement in the rear chamber C is brought to the center of the chamber C by the left and right conveyors 22a and 22b, and is stirred there by the stirring wheel 22c and the metering rotary feeder 23. While being mixed, the liquid is sent to a kneading device 36, which will be described later, via the discharge side opening 23a of the feeder 23 and the chute 19 connected thereto.

Furthermore, the feeder 23 is also provided with an elastic body 23b similar to the elastic body 17b.

At the lower rear end of the vessel 3, a conveying and mixing device 20 is provided along the rear wall, and the device 20 is provided with left and right conveying chambers 31 and 32 separately on the left and right sides, respectively.
The transfer chambers 31 and 32 both have a cylindrical shape. The transfer chamber 31 is in contact with the floor 6 of the carry-in passage 12 and extends from the left end of the carry-in passage 12 to almost the center of the vessel 3, and the front thereof is cut out and communicates with the rear opening of the carry-in passage 12.
The right end of the transfer chamber 31 has a central mixing transfer port 31a at the rear.
Open your mouth. Further, a left screw conveyor 28 is fitted and supported in this transfer chamber 31, and a hydraulic motor 26
are connected to form the left conveyor. On the other hand, the transfer chamber 32 is in contact with the floor 6 of the carry-in path 13 and the transfer chamber 31
It extends slightly forward of the transport chamber 31 from the right end of the carry-in path 13 to approximately halfway between the left and right ends of the transfer chamber 31 .
The front part is cut out during the width that contacts the carry-in passage 13, and communicates with the rear opening of the carry-in passage 13. The left end of the transfer chamber 32 is open as a transfer end 32a. A right screw conveyor 29 is fitted and supported in the thus constructed transfer chamber 32, and a hydraulic motor 27 is connected thereto, thereby forming a right transfer machine.

Next, the kneading device 36 disposed behind the conveying and mixing device 20 will be explained. A bracket 35 is provided at the rear of the vessel 3, and a kneading container 37 is pivotably supported 38 so as to be able to rise and fall freely. This shaft 38 is the pivot shaft 4
In contrast, when the vessel 3 is horizontal (the state shown by the solid line in FIG. 1), it is positioned forward and upward. More precisely, the shaft 38 is set so that it is almost at the top of its rotation when the vessel 3 is tilted (the state shown by the solid line in FIG. 5). A wire locking piece 24a is provided on the container 37 to project sideways, and one end of the wire locking piece 24a is locked to the wire locking piece 24a.
Bracket 24b provided on the rear wall of Bethel 3
A wire 24f is wound around a hydraulically driven winch 24e provided on the same axis as the pivot shaft 4 via a free rotation pulley 24d which is supported by a shaft 24c.
Thus, with the above configuration from 24a to 24f,
Rotating means for the kneading device 36 is configured.

Next, the details inside the container 37 will be described in detail. container 3
A conveyance passage 37a is formed inside 7 in the front-rear direction. At the base end of the container 37, there is a material entrance 37.

7e are separated bottom walls of the containers 37, respectively. Further, the bottom walls 37d and 37e are each formed double with a space as shown in FIG. 8, and are also formed in a lattice shape. Reference numeral 37f denotes an elastic plate made of rubber or the like, which is mounted so as to be sandwiched in the space of the bottom wall 37d. Reference numeral 37g is an elastic plate made of rubber or the like which is attached to the bottom wall 37e so as to be sandwiched therebetween. The base end of the bottom wall 37d is hinged 37h to the lower part of the container 37, the base end of the bottom wall 37e is hinged 39 to the container 37, and both bottom walls 37d,
The other ends of 37e are removably connected by a connecting fitting 40. By removing the metal fitting 40, both bottom walls 37d and 37e are rotated downward in FIG. 8, and the bottom of the container 37 can be opened.

S ₁ is connected to the passage 37a on the loading port 37b side of the container 37.
This is a mixing shaft that is supported in a direction perpendicular to the .

3, 44, 45, 46, 47 are gears with the same number of teeth that are integrated with the mixing shaft and each of the kneading shafts _S2 to _S5 ,
Each gear meshes with its adjacent gear. Therefore, the mixing shaft S ₁ and the kneading shafts S ₃ and S ₅ can be rotated counterclockwise as shown by the arrows in FIG. 8, and the kneading shafts S ₂ and S ⁴ can be rotated clockwise.

The scraping mixing blade 48 and the shearing and folding kneading blades 49 to 52 attached to the mixing shaft S ₁ and each of the kneading shafts S ₂ to _{S 5} will be explained below. Blades on L-L are marked with the code "c", and blades located below the center line L-L in Figure 7 are marked with the code "l".
The blade located above the center line LL in FIG. 7 is designated by the symbol "r".

Reference numeral 48 denotes a total of nine scraping mixing blades attached to the mixing shaft S ₁ in a staggered manner with a phase difference of 180 degrees, and the aggregate mixed material discharged from the conveying port 27 is moved in the vertical direction in Fig. 7. It is designed to mix and scrape toward the center. i.e. blade 4
The blades 8l are all inclined in the same direction with respect to the mixing axis _S1 , and the blades 48r are all inclined in the opposite direction to the blade 48l. Also, the blade 48c is inclined in the same direction as the blade 48r, so that the material ends up in the seventh
The mixture is mixed and scraped together slightly below the center line LL as indicated by arrow B in the figure.

Reference numerals 49, 50, and 51 designate seven hook-shaped shear kneading blades each attached to each of the kneading shafts _S2 to _S4 in a staggered manner with a phase difference of 180 degrees. In FIG. 7, the concrete mixture is kneaded and brought toward the center in the vertical direction.

That is, the blades 49l are all inclined in the same direction with respect to the kneading axis _S2 , and the blades 49r are all inclined in the opposite direction to the blade 49l. Also blade 49
c is inclined in the same direction as the blade 49l, and the concrete mixture mixed by the blade 48 is kneaded by the blade 49 toward a position slightly above the center line L-L as shown by the arrow C in FIG. However, it is sent to me.

Furthermore, as is clear from _FIG .
Blade 5 is inclined in the opposite direction to 9l and 49r.
0c is inclined in the same direction as the blade 50r. In the end, the concrete mixture kneaded by the blade 49 is kneaded and brought to a position slightly below the center line LL by the blade 50 as indicated by the arrow D in FIG.

Further, the directions of the blades 51 with respect to the kneading axis _S4 are all inclined in the same direction as the directions of the blades 49 with respect to the kneading axis _S2 . Blade 50 after all

Reference numeral 52 denotes a total of seven folded kneading blades installed in a staggered manner with a phase difference of 180° on the kneading shaft _S5 . This is done in order to knead and bring it together.

Note that the blades 52l, 52c, 52r are the seventh
As is clear from the figure, blades 48l, 48c,
The concrete mixture tilted in the same direction as 48r and eventually mixed by the blade 51 is
The blade 52 kneads and brings the material to a position slightly below the center line LL as indicated by the arrow F in FIG.

Reference numeral 53 denotes a frame-like frame body hinged 54 on the top surface of the container 37, and is designed to prevent the concrete mixture from flowing out from the top surface of the container 37, and from the upper and lower ends in FIG.

On the other hand, in front of the Bethel 3, a water tank 57 and a hydraulically driven water pump 58 for pumping the water stored in the water tank 57 are installed on the frame of the vehicle, and are connected to the discharge port of the water pump 58. The water supply pipe 60 is extended to the rear of the vehicle V, and its open free end opens into the kneading container 37.

In addition, 61 in the figure is an outrigger provided on the main frame 1 of the vehicle V.

Next, to explain the case where the vehicle V loaded with concrete materials mixes and generates ready-mixed concrete at a construction site etc. as described above, after the vehicle V has stopped, the outriggers 61 are first extended to support the frame 1, Next, the lift cylinder 5 is extended and the vessel 3 is tilted rearward around the pivot shaft 4 as shown by the solid line in FIG. 5 (or the two-dot chain line in FIG. 1).

In this case, the winch 24e is activated and the wire 2
4f, the kneading device 36 tilts around the shaft 38 due to its own weight, as shown by the solid line in FIG.
Hold it in a slightly downward position.

Left and right ventricles A and B due to the backward tilt of Bethel 3 mentioned above.
The coarse aggregate and sand inside move to the rear of the vessel 3 due to their own weight and enter the left and right carry-in paths 12 and 13 located at the lower rear of the vessel 3. Right ventricle B here
stirring wheel 15 and quantitative rotary feeder 16,1
7 together in the direction shown in the figure, the sand is first stirred and loosened by the stirring wheel 15, and then the sand is moved to the feeder 1.
6, 17, left and right loading paths 12,
13 from the rear end into the left and right transfer chambers 31 and 32.

In this case, in the left entry path 12, if there were no wall 9, smaller gravel among the gravel stored in the left chamber A would normally slide down first due to the difference in the angle of repose, but this In the example, as shown in FIG. 9, among the gravel stored in the left chamber A, the gravel in the divided chamber _A1 is:
Those having approximately average dimensions are fed to rollers 14 and feeder 16. Eventually, the amount of gravel in chamber A ₁ will decrease, and the large-sized gravel remaining in chamber A ₁ will then slide down and reach the feeder 16, but at the same time, the average-sized gravel in chamber A ₂ will fall onto the wall. The feeder 16 is supplied with gravel of a size that is not so uneven. Room A ₁
After all of the gravel has been discharged, the chambers A ₂ , A ₃ . It is. It will be appreciated that the greater the number of walls 9 to subdivide the chamber A, the more constant the density of the gravel can be. Furthermore, as mentioned earlier, by adjusting the front and rear positions of the rollers 14, the feeder 1 can be adjusted to correspond to the size of the gravel.
It is possible to expect accurate metering and feed without gravel getting caught in the 6.

Furthermore, the sand contained in the right ventricle B has a larger angle of repose than the gravel in the left ventricle A, but the inclination angle of the floorboard 6 of the right ventricle B is larger than that of the left ventricle A.
The friction reducing plate 6a allows sand to slide down at the same time as gravel.

The coarse aggregate and sand carried into the left and right conveyance chambers 31 and 32 from the left and right carry-in paths 12 and 13 in this manner are carried by left and right screw conveyors 28 and 29 rotating in the direction shown in the figure. gradually moved towards the center. By the way, when the Bethel 3 is tilted, the screw conveyor 29
is located above the screw conveyor 28, so
The sand conveyed by the screw conveyor 29 is
The gravel and sand fall from the conveying end 32a onto the gravel being conveyed by the screw conveyor 28, and the gravel and sand are mixed together and further transferred by the screw conveyor 28, and are then transferred to the inlet 3 of the kneading device 36.
7b From the transport port 31a opened above, the transport port 37
falls into b.

Meanwhile, at the same time, the transport vehicle 22 is also inside the rear chamber C.
a, 22b, the stirring wheel 22c, and the rotation of the quantitative rotary feeder 23 in the directions shown in the figure, the cement at the inner bottom of the rear chamber C is conveyed to the center, stirred, weighed by the quantitative rotary feeder 23, and shot out from the opening 23a. 19, and is dropped into the front entrance 37b of the kneading device 36. If the transport vehicle 22a,
If the stirring wheels 22b and 22c become clogged, the motor 25 is rotated in reverse to loosen them. At this time, the feeder 23 does not rotate due to the operation of the one-way clutch.

As these feeders 17 and 23 rotate in the direction of the arrow shown in the figure, the free ends of the elastic bodies 17b and 23b are repelled by the wings of the feeders 17 and 23, and the sand and cement in the valley between the wings are repelled. Since sand and cement are not stuck in these valleys, accurate measurement can be expected.

As described above, coarse aggregate, a mixture of sand, and separate cement are carried into the mixing container 37 to produce fresh concrete, and the pump 58 is driven to pass the water from the water tank 57 through the water supply pipe 60. Since pressurized water is then supplied, the cement does not solidify due to moisture in the aggregate during transportation.

At this time, the container 37, that is, its passage 37a,
It slopes downward to the right as shown by the solid line in Figure 5. Therefore, the above-mentioned aggregate mixture and cement are gradually conveyed mainly by their own weight toward the outlet 37c, but in the meantime, they are first scraped and mixed by the blade 48, and the mixture is further mixed with the water supplied from the water supply pipe 60. In addition, the blades 49 to 52 perform pushing/pulling, shearing, and folding actions in a direction perpendicular to the passage 37a, thereby successively kneading.

That is, the mixing and kneading of the concrete materials by the blades 48 to 52 is performed in accordance with arrow B in FIG.
As is clear from ~F, the materials and mixtures are arranged alternately above and below the center line LL in FIG. 7 for each adjacent mixing axis _S1 and kneading axis _S2 ~ _S5 . Therefore, the materials and mixtures near the center line LL are sufficiently mixed and kneaded. In addition, all the blades 48 to 52 are designed to gather the material or mixture toward the center of the container 37, but during this gathering, the material or mixture is subjected to a force that tends to return toward the edges. As a result, the materials and mixture are eventually pushed and pulled in a direction perpendicular to the passage 37a, and are sufficiently kneaded.

All blades 48 to 52 are made of materials,
Since the mixture is gathered toward the center, there is no possibility that the material or the mixture remains at the left and right ends (upper and lower ends in FIG. 7) of the passage 37a.

If the sufficiently kneaded mixture is filled above the lower end level of the carry-out port 37c, the carry-in port 37c
The amount carried in from b is carried out from the outlet 37c.

During the operation, the height of the outlet 37c from the ground is increased due to the rise of the container 37 due to the rise of the shaft 38. Therefore, by connecting a chute (not shown) to the outlet 37c, it is possible to move the outlet 37c as far as possible. The mixture can be transferred to

The discharge capacity of the coarse aggregate, sand, cement, etc. can be arbitrarily determined by adjusting the rotational speed of each motor 19, 18, and 25 by a control means (not shown).

Further, after discharging the kneaded material, the lift cylinder 5
As a result of the contraction, the vessel 3 is laid down on the frame of the vehicle V, the wire 24f is retracted, the kneading container 37 is rotated upward and retracted, and the vehicle is returned to the running position.

In the above embodiments, the rotating means of the kneading device 36 was composed of a wire, a winch, and the like. This configuration has the effect that even if the kneading device 36 interferes with a structure on the ground due to the tilting of the vessel 3, the rotating means will not be damaged due to slack in the wire. A known actuator may be connected between the vessel 3 and the kneading device 36. Further, the kneading device 36 may be pivoted to the frame 2 instead of the vessel 3. In addition, replacement of each component of this invention with equivalents is also included within the technical scope of this invention.

As described above, according to the present invention, concrete materials such as coarse aggregate, sand, and cement, and water are transported as they are to the concrete placement site, or their mixing ratio can be freely adjusted there by replenishing on-site. In the vehicle V, which is capable of continuously mixing and producing the required amount of ready-mixed concrete, the inside of the vessel 3 mounted on the frame 2 is shown on the left,
It is divided into a right chamber and a rear chamber A, B, and C, and concrete materials such as coarse aggregate, sand, and cement are stored separately in these chambers. Since the material is moved toward the left and right conveyors installed along the vessel, the overall structure can be simplified without requiring any means for conveying these materials in the longitudinal direction of the vessel 3. The volume of Bethel 3 can be increased.

In particular, the left, right and rear chambers A, B and C are each independently passed through the left and right transfer chambers and kneading devices 31, 32 and 36 of the left and right transfer machines via metering feed devices; Among the concrete materials stored separately in the left, right, and rear chambers A, B, and C, the aggregate mixture and cement are each independently carried into the mixing device 36, where they are combined and mixed for the first time. As a result, concrete materials such as coarse aggregate and sand are not mixed with cement in advance inside Bethel 3 and inside the left and right transfer chambers 31 and 32, and sand in a wet state is used as a concrete material. etc., the mixture of them and cement will partially solidify inside the Bethel 3 and the left and right transfer chambers 31, 32, etc. due to the moisture contained in them, causing the ready-mixed concrete to become heterogeneous. There is no possibility of problems such as drying, drying, or solidified matter interfering with the operation of the apparatus or damaging a conveying machine such as a screw conveyor.

Furthermore, sand and gravel as concrete aggregates are intensively mixed to some extent in the left conveyance chamber 31 before being sent to the kneading device 36 where they are mixed and kneaded with cement and water, so that these materials are It is reliably kneaded in a short time and homogenized over the entire amount, making it possible to mix and produce optimal ready-mixed concrete.

It is also possible to knead and produce mortar by stopping the metering and feeding of the coarse aggregate and using only sand as the aggregate.

Furthermore, all the devices that require maintenance such as stirring, metering, conveyance, mixing, and kneading can be installed at the rear of the vessel, making their maintenance extremely easy.
