DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment will be described with reference to FIGS. FIG. 1 is a plan view of a self-propelled remaining soil recycling vehicle according to a first embodiment,
FIG. 2 is a side view thereof. In the figure, 1 is a residual soil supply device, 2 is a soil conditioner supply device, 3 is a crusher, 4 is a vibrating screen for classifying soil particles, and 5 is a belt conveyor.
These residual soil treatment devices are arranged in a line in the front-rear direction substantially on the center line of the crawler type vehicle body 6 while partially overlapping in the vertical direction. The vehicle body devices (that is, devices and operating space necessary for running the vehicle and operating the remaining soil treatment line) are arranged on both sides of these remaining soil treatment devices. That is, an engine 7 for driving the vehicle body and a soil conditioner silo 21 which is a part of the soil conditioner supply device are disposed on one side of the vehicle body 6 with each of the above-mentioned remaining soil treatment devices interposed therebetween, and a fuel tank 8 is provided on the other side. And an operating space 9 are arranged.

The residual soil supply device 1 includes a hopper 11 disposed at one end of a frame provided on the vehicle body 6 and a belt conveyor 12.
The constant amount of the residual soil put into the hopper 11 is supplied to the crusher 3 via the belt conveyor 12.

The soil conditioner supply device 2 is a device for supplying a fixed amount of the soil conditioner stored in the soil conditioner silo 21 to the remaining soil on the belt conveyor 12 via a feeder 22. The feeder 22 is provided with a coil on the inner periphery thereof which is rotationally driven by a hydraulic motor 23. The rotation of the coil transfers the soil improving agent in the soil improving agent silo 21 onto the belt conveyor 12 and scatters the soil improving agent. The soil conditioner is, for example, lime or cement, and the applied amount is 3 to 5% based on the remaining soil.

The crushing machine 3 crushes the residual soil supplied from the belt conveyor 12, and crushes the residual soil with the feeder 22.
This is a device for mixing with the soil conditioner introduced from the above. That is, the crusher 3 is disposed near the front of the vehicle body of the residual soil supply device 1 and has an inner shape that expands from the bottom to prevent external leakage of dust generation. In addition, it is a four-axis type in which the mixing property is hardly reduced due to the adhesion of the residual soil. Specifically, drive rotors 31 and 33 driven to rotate inward by hydraulic motors 35 and 36, and these drive rotors 31 and 33
Driven rotors 32 and 34 are provided below the inside, and by the rotation of these, the remaining soil and the soil conditioner are kneaded to form an improved soil, and then the improved soil is placed on a belt conveyor 37 provided below. It is made to fall.

The belt conveyor 37 conveys the improved soil to a position above the vibrating sieve 4 serving as a soil classifier.

The vibrating sieve 4 is used when the grain size standard is applied to the improved soil, and classifies the improved soil into an undersize and an oversize. The undersize falls through a vibrating screen 4 onto a belt conveyor 5 provided below, and is conveyed to the front of the vehicle body 6 by the belt conveyor 5. On the other hand,
The oversize is carried out to the side of the vehicle body 6 by a slide provided on the vibrating screen 4. When the improved soil is not classified, the vibrating sieve 4 is removed, and all the improved soil is carried out by the belt conveyor 5. The belt conveyor 5 has one end rotatably mounted on the front part of the vehicle body 6 and is held by a fishing support device 51.

The effect of the first embodiment will be described. According to the first embodiment, the remaining soil treatment device is arranged substantially on the center line of the vehicle body 6, and the driver's seat is arranged at the front like a conventional truck-mounted type self-propelled soil improvement plant. In addition, it is disposed on the side of the residual soil treatment device, and the engine for driving the vehicle body, other devices and the like are also disposed on the side, and further, the belt conveyors 12, 37, and 5 are all terminated at the end from the beginning. Because it is arranged at an angle to be higher,
Vehicle length during processing can be shortened. Therefore, it is suitable for use in a narrow site. In addition, the vehicle body device and the remaining soil treatment device do not overlap each other vertically, the vehicle height is reduced, and the loadability of the remaining soil is good.

Incidentally, to give an example of actual specifications of the test machine of the first embodiment, a vehicle width of 1980 mm, a vehicle height of 2500 mm and a vehicle volume of 4
about ton. That is, according to the first embodiment, since the residual soil treatment device is disposed substantially on the center line of the vehicle body and the vehicle body devices are disposed on both sides of the vehicle body, the vehicle is compact and the mobility is improved. In addition, since a crawler-type traveling body is used, it can be easily moved regardless of uneven terrain or a narrow place. The crawler type may be a wheel type.

Hereinafter, another embodiment will be described with reference to the drawings.

The second embodiment has the configuration shown in FIG. That is, the belt conveyor 12 in the first embodiment is abolished,
Instead, as shown in a part P in the figure, a horizontal rotary feeder 13 is provided directly above the crusher 3, and a hopper 11 for charging residual soil is provided directly above the horizontal rotary feeder 13. The other configuration is the same as that of the first embodiment. In FIG. 3, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

The section P, that is, the details of the horizontal rotary feeder 13 will be described with reference to FIGS. 4 and 5. FIG. As shown in FIG. 4, two cylinders 111 and 112 are supported by members (not shown) between the input port of the hopper 11 and the input port of the crusher 3. A rotating plate 131 is provided in a gap between the input port of the hopper 11 and the upper opening of the cylinder 111, and a rotating plate 132 is provided in a gap between the lower opening of the cylinder 111 and the upper opening of the cylinder 112.
However, a rotating plate 133 is slidably housed between the lower opening of the cylinder 112 and the inlet of the crusher 3. The rotating plates 131, 132, 133 are coaxially fixed to each other in parallel with each other and in a direction perpendicular to the central axis 134. The shaft 134 can be driven to rotate by a hydraulic motor 130, for example. Each of the rotating plates 131, 132, and 133 is shown in FIG.
2), as shown in (13), holes m1, m2,
m3. Hole m1 of rotating plate 131 and rotating plate 13
3 at the same position as the hole m3, and the hole m2 of the rotary plate 132.
Are the holes m1, m3 of the rotary plates 131, 133, respectively.
Is provided at a position which is 180 degrees out of phase.

The operation of the horizontal rotary feeder 13 will be described with reference to FIG. The relative positions of the rotating plates 131, 132, 133 are respectively shown in FIG. 5 (11), (12), (13).
In this state, the inlet of the hopper 11 and the upper opening of the cylinder 111 are shut off because the hole m1 of the rotating plate 131 is located outside the cylinder. As a result, the residual soil in the hopper 11 does not fall into the inside A of the cylinder 111. However, since the hole m2 of the rotating plate 132 is located inside the cylinder, the inside A of the cylinder 111 and the inside B of the cylinder 112 communicate with each other.
Remains fall into the interior B. However, the remaining soil that has fallen into the interior B is thrown into the crusher 3 because the hole m3 of the rotating plate 133 is located outside the cylinder, so that the lower opening of the cylinder 112 and the inlet of the crusher 3 are blocked. It will not be done. FIG. 5 (10) illustrates the above. So next,
By rotating the shaft 134 by 180 degrees by the motor 130, the rotating plates 131, 132, and 133 are rotated as shown in FIGS.
When the state is changed to the state of (23), the hole m3 of the rotating plate 133 is located inside the cylinder, and the lower opening of the cylinder 112 communicates with the input port of the crusher 3, so that the remaining soil in the internal B is in the crusher 3. It is thrown into. At the same time, the hole m1 of the rotating plate 131 is also located in the cylinder, so that the input port of the hopper 11 communicates with the upper opening of the cylinder 111, and the remaining soil in the hopper 11 falls into the interior A. However, since the hole m2 of the rotating plate 132 is located outside the cylinder, the lower opening of the cylinder 111 and the upper opening of the cylinder 112 are shut off, and the remaining soil in the interior A does not fall into the interior B. FIG. 5 (20) illustrates the above. Since the horizontal rotary feeder 13 is configured as described above, for example, when the motor 130 is rotated at a constant speed, the remaining soil is injected into the crusher 3 in a fixed amount. In addition, if you increase the rotation speed,
By changing the number and size of the holes m1, m2, and m3, the amount of residual soil input to the crusher 3 can be made variable. The soil conditioner is sprayed from the illustrated feeder 22 to the remaining soil, as in the first embodiment.

The effect of the second embodiment will be described. According to the second embodiment, since the belt conveyor 12 of the first embodiment is eliminated, the overall length can be shortened. In addition, it is possible to change the number and size of the holes m1, m2, and m3 to perform the fixed amount and variable amount of the residual soil into the crusher 3 with high accuracy by simply changing the rotation speed of the motor 130. It can be carried out. As a result, excessive loading of the residual soil into the crusher 3 is eliminated, and overload operation can be eliminated. In addition, it is possible to urgently stop the surplus soil input in an emergency. Furthermore, synchronous control with the feeder 22 for obtaining the optimum mixing ratio between the soil conditioner and the remaining soil can be easily performed. The belt conveyor 12 of the first embodiment can also change the drive speed to perform constant or variable input of the residual soil to the crusher 3. For example, when the drive speed of the belt conveyor 12 is reduced, the hopper 11 Since the amount of soil remaining on the belt conveyor 12 also increases, the accuracy of fixed-quantity feeding and variable feeding is not as high as that of the horizontal rotary feeder 13. Further, since the driving force of the horizontal rotary feeder 13 is smaller than the driving force of the belt conveyor 12 of the first embodiment, energy saving can be achieved by that much.

The third embodiment has a configuration shown in FIG. That is, the horizontal rotary feeder 13 in the second embodiment is eliminated, and the hopper 11 is replaced with a hydraulic actuator 111, for example.
And can be swung. That is, the swing type hopper 11
As shown in FIG. 6, a is attached so as to be rotatable around the pin 112, and is swingable around the pin 112 by the operation of the actuator 111. FIG. 6
(1) shows a state where the remaining soil is not supplied to the crusher 3. On the other hand, FIG. 6B shows that the oscillating hopper 11a is tilted by extending the hydraulic cylinder serving as the actuator 111,
This shows a state in which the remaining soil is being injected into the crusher 3 from an inlet provided at the lower part. Adjustment of the amount of remaining soil charged into the crusher 3 can be easily performed by adjusting the amount of expansion and contraction of the hydraulic cylinder 111, that is, by changing the swing angle to change the input area. Reference numeral 113 denotes a bellows-type baffle for preventing the remaining soil from going outside when the remaining soil is put into the crusher 3. The soil conditioner was the same as in the first embodiment.
It is sprayed from the illustrated feeder 22 on the remaining soil.

The effect of the third embodiment will be described. According to the third embodiment, since the belt conveyor 12 of the first embodiment is eliminated, the overall length can be shortened. In addition, only by changing the swing angle, the area of the charging port can be changed and the falling force of the remaining soil can be changed, so that the fixed amount of the remaining soil to the crusher 3 and the variable input can be performed with high precision. As a result, as in the second embodiment, the overload operation can be prevented, the emergency injection of the remaining soil can be stopped in an emergency, and the synchronous control with the feeder 22 for obtaining the optimum mixing ratio between the soil conditioner and the remaining soil can be easily performed. Can be done. Further, since the structure is simple, troubles hardly occur and maintenance is easy. Further, since the driving force is small, energy can be saved. Further, for example, when the remaining soil is charged into the oscillating hopper 11a by a loading machine, as shown in the figure, the loading port can be made lower, so that the loading becomes easier. Furthermore, even if the remaining soil is sticky soil, it is possible to prevent the sticky soil from adhering to the inner wall of the hopper 11a by swinging the hopper 11a, so that the working efficiency is improved.

The fourth embodiment has the configuration shown in FIG. That is, the horizontal rotary feeder 13 in the second embodiment is abolished, and instead, a rotary feeder 13a that is divided into several chambers and that rotates, for example, vertically is provided. That is, as shown in FIG. 7, when the rotary feeder 13a is rotated by a motor (not shown), the residual soil falls from the hopper 11 and accumulates in the upwardly-facing chamber, and when the rotation is made, this chamber is downwardly oriented. The remaining soil is put into the crusher 3. The soil conditioner is sprayed from the illustrated feeder 22 to the remaining soil as in the first embodiment.

The effect of the fourth embodiment will be described. According to the fourth embodiment, since the belt conveyor 12 of the first embodiment is eliminated, the overall length can be shortened. Further, the fixed amount or the variable amount of the residual soil into the crusher 3 can be precisely performed only by changing the rotation speed of the rotary feeder 13a. As a result, similarly to the second embodiment, the overload operation can be prevented, the input of the residual soil can be stopped in an emergency, and the synchronous control with the feeder 22 for obtaining the optimum mixing ratio of the soil conditioner and the residual soil can be easily performed. . Also, since the structure is simple, troubles are less likely to occur,
Also, maintenance is easy. In addition, since the driving force is small, energy saving can be achieved.

The fifth embodiment has the configuration shown in FIG. That is, separately and adjacent to the hopper 11 in the fourth embodiment,
Alternatively, a separate hopper is provided to partition the inside of the hopper 11, and this is used as a hopper 11b for charging the soil conditioner. The supply adjusting unit 2 is provided at the input port below the hopper 11b.
3a is provided. In the fifth embodiment, the supply adjusting section 23a is a baffle plate that can be shielded from the lower input port of the hopper 11b. In the fifth embodiment, as in the above embodiments, a soil conditioner silo 21 and a feeder 22 may be provided, and the soil conditioner may be supplied from the feeder 22 into the hopper 11b. The agent silo 21 and the feeder 22 may be eliminated and only the hopper 11b may be used.

The effect of the fifth embodiment will be described. According to the fifth embodiment, the same effects as those of the fourth embodiment can be obtained, and the structure can be simplified because the soil conditioner silo 21 and the feeder 22 can be eliminated. Therefore, the occurrence of troubles is reduced, and the maintenance becomes easy.

In each of the above embodiments, as shown in FIG. 2, when not in use, the belt conveyor 5 is detached from the shaft and detached from the fishing support device 51, and is indicated by a chain line in FIG. Thus, it is preferable to be able to store in the lower part of the vehicle body 6. When the belt conveyor 5 can be stored in the vehicle body 6 in this manner, the vehicle length during movement can be shortened. Therefore, movement on narrow roads and sites is facilitated, and mobility is further improved.
