Description

Technical Field

[0001] The present invention relates to a mud removal device that quickly washes off dirt such as mud adhering to the tires of construction vehicles entering and leaving construction sites, etc. More specifically, it relates to a wet soil discharge device that prevents the mud washed off from the tires of construction vehicles and their vicinity from simply accumulating downward, and efficiently discharges the mud to the outside.

Background Art

[0002] In various sites such as civil engineering and construction, when a construction vehicle exits the site, if foreign matters such as mud and small stones (hereinafter simply referred to as "mud") adhering to the tires of the vehicle and their vicinity are left as they are, the mud will fall from the exited vehicle, contaminating the environment around the site. Therefore, at the site, the tires, etc. are cleaned at the time of exit to prevent the mud adhering to the vehicle from being carried out of the site.

[0003] As a method of removing the mud adhering to the vehicle, there is a method of washing off the dirty tires using a high-pressure washer. However, when using a high-pressure washer, a power source such as a power supply or an engine is required, and personnel to handle the high-pressure washer is also required. At this time, if the driver of the construction vehicle himself / herself becomes the person handling the high-pressure washer, he / she has to get out of the driver's seat each time when exiting the site, which is unavoidably troublesome.

[0004] Also, in the case of a large vehicle such as a construction vehicle, since the driver's seat is at a high position, getting on and off is very difficult, and an increase in the number of times of getting on and off may induce falling or jumping off, thereby causing the risk of injury. Moreover, in the case of rain, since the soles of the shoes and the steps are wet, the risk of slipping and getting injured due to the rain further increases.

[0005] On the one hand, there is also a method of creating a puddle of water through which a vehicle passes near the exit of the work site, submerging the tires, and washing away the dirt on the tires. This method does not require electricity, and moreover, the driver of the construction vehicle does not need to get in and out each time, and can easily handle it. However, it cannot sufficiently remove the mud that has entered and strongly adhered to the grooves of the tires, or the mud that has adhered to the lower surface and side surfaces of the construction vehicle.

[0006] Therefore, a mud removal device has been conventionally proposed that uses the self-rotating power of a construction vehicle to rotate a pump and utilizes the pressure of a cleaning medium such as water ejected from nozzles installed to hit the lower surface and side surfaces of the vehicle to quickly wash away the mud adhering to the tires (see, for example, Patent Documents 1 and 2). This mud removal device does not require electricity, the driver of the construction vehicle does not need to get in and out each time, and moreover, it can sufficiently remove the mud that has strongly adhered to the tires, or the mud that has adhered to the lower surface and side surfaces of the construction vehicle.

[0007] However, the above-described mud removal device is divided into a movable front-wheel slope, rear-wheel slope, and intermediate slope, and a front-wheel part and a rear-wheel part that are difficult to move. The front-wheel part and the rear-wheel part are welded with several bases and fixing brackets so as not to move when the construction vehicle rides on them. Therefore, there is a problem that mud accumulates in the lower parts of the front-wheel part and the rear-wheel part that are difficult to move.

[0008] That is, in this mud removal device, the mud adhering to the lower surface and side surfaces of the construction vehicle is washed away from the vehicle by the front-wheel mud removal roller provided in the front-wheel part, the rear-wheel mud removal front roller and the rear-wheel mud removal rear roller provided in the rear-wheel part. Therefore, the washed-away mud accumulates as it is in the lower parts of the front-wheel part and the rear-wheel part that are difficult to move.

[0009] However, the distance between the lower surface of this mud removal device and the ground is as narrow (low) as about 100 to 250 mm. In a narrow work site, it is difficult to lift each main body for cleaning, and since the front wheel part and the rear wheel part installed in a place where mud accumulates are fixed so as not to move, it takes time and labor to scrape out the deposits from under the mud removal device.

[0010] Also, to increase the distance between the lower surface of the mud removal device and the ground, it is necessary to increase the height of the entire mud removal device. In that case, however, since the line of sight of the operator of the construction vehicle becomes higher, there is a risk of giving a sense of fear to the power line operator. Moreover, in order to keep the inclination angles of the front wheel slope and the rear wheel slope low, it is necessary to make the slopes longer. However, there are many narrow work sites where there is no installation space, and since it is necessary to keep the length of the slopes to a minimum, it cannot be easily dealt with.

[0011] Under such circumstances, currently, the accumulated mud is dealt with by manually removing it outside the mud removal device using a high-pressure washer or a T-shaped scraping tool called a dragonfly. However, as described above, the operation of scraping out the mud deposits from between the low-height lower surface of the mud removal device and the ground has to be carried out in a hunched mid-back posture, which is extremely troublesome and difficult, and actually requires a considerable amount of time and labor. Moreover, since the lower surface of the mud removal device cannot be visually confirmed clearly, there is also a high possibility that frequent work will be required due to scraping leakage.

[0012] Therefore, in order to be able to quickly remove the mud deposited below the mud removal device as described above, a receiving box-type earth discharge device with moving wheels equipped with a bottom plate for accumulating the falling mud is proposed to be pushed between the lower surface of the mud removal device and the ground and is configured to be pullable (see, for example, Patent Document 3). With this device, by pulling out the receiving box body, it becomes possible to simply and quickly remove the mud that has accumulated and dried below the mud removal device.

[0013] However, in the case of the receiving box type earth discharging device disclosed in Patent Document 3, attention must be paid to the height of the earth and sand deposited in the receiving box body. That is, even in the case of this receiving box type earth discharging device, the washed earth and sand will still accumulate below the earth removing device. In order to remove the accumulated earth and sand, it is necessary to pull out the receiving box body from below the earth removing device. In addition, when using the above earth removing device that uses water, muddy water will accumulate inside the box due to its box shape, and the life (durability) of the receiving box body will be reduced.

Summary of the Invention

Problems to be Solved by the Invention

[0015] The present invention has been developed in view of the above conventional circumstances. In an earth removing device that quickly washes off the earth and sand adhering to the tires of a construction vehicle, it is possible to prevent the earth and sand washed off from the tires and their vicinity from accumulating directly below, and to efficiently discharge the earth and sand from below the earth removing device to the outside. The purpose is to provide a technology that enables this.

Means for Solving the Problems

[0016] The wet soil discharging device according to the present invention is a wet soil discharging device installed below a soil removing device that quickly washes off the soil adhering to the tires of a construction vehicle, and has a soil receiving area for receiving a cleaning liquid containing the soil falling from above, and the soil receiving area is characterized in that it is inclined downward in at least one direction toward the outer edge portion.

[0017] In the above-described wet soil discharging device, the soil receiving area can be made concave along the inclined direction. Further, when the soil receiving area is concave, the soil receiving area can be a V-shaped cross-section having two flat slopes facing each other with the inclined direction as the axis. Furthermore, when the soil receiving area is a V-shaped cross-section, the bottom of the soil receiving area can also be rounded. Here, the bottom refers to the valley portion on the lower position side of the slope.

[0018] Also, in the above-described wet soil discharging device, the soil receiving area may be flat and further have an overflow prevention area for preventing the cleaning liquid containing the soil from overflowing from the outer edge portion of the soil receiving area. When the soil receiving area is flat, the overflow prevention area is formed at the outer edge portions at positions facing each other across the soil receiving area, and the soil receiving area can be inclined toward the outer edge portion where the overflow prevention area is not formed. That is, when the soil receiving area is flat, the overflow prevention area may be provided on the entire outer edge portion around the soil receiving area, or the overflow prevention area may be provided at the outer edge portions at positions facing each other across the soil receiving area, and it may be inclined downward in at least one direction toward the outer edge portion where the overflow prevention area is not formed.

[0019] Also, in the above-described wet soil discharging device, the soil receiving area can be inclined downward in two separating directions. Also, in the above-described wet soil discharging device, the soil receiving area may have a low sliding resistance.

[0020] Further, the wet earth removal device described above may further include movable means for facilitating the movement of the installation location. Further, the wet earth removal device described above may further include a cleaning liquid supply means for injecting a cleaning liquid toward the mud receiving area. Furthermore, the wet earth removal device described above may further include a vibration applying means for applying vibration to the mud receiving area. Furthermore, the wet earth removal device described above may be directly installed on the mud dropping device and utilize the vibration generated during the mud dropping operation of the mud dropping device to act on the falling of the earth.

Advantages of the Invention

[0021] According to the present invention, in a mud dropping device configured to quickly wash off the earth adhering to the tires of a construction vehicle or the like, the cleaning liquid containing the washed-off earth is efficiently discharged (flowed out) from below the mud dropping device to the outside. That is, the cleaning liquid containing the washed-off earth is guided by the momentum of the flowing cleaning liquid and the weight of the earth to the slope below the mud receiving area and is easily discharged toward the outer edge of the mud receiving area. Therefore, in the device of the present invention, the earth washed off below the mud dropping device does not accumulate as it is. Thus, it is possible to eliminate the trouble of shoveling out the earth from below the mud dropping device and the trouble of pulling out the receiving box body with the accumulated earth from below the mud dropping device while paying attention to the height of the accumulated earth.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, an example of an embodiment of the wet earth discharging device according to the present invention will be described with reference to the drawings. The wet earth discharging device according to the present invention is installed and used below a mud removing device that quickly washes away mud and other foreign matters such as mud and small stones adhering to the tires of a construction vehicle and the vicinity thereof, and efficiently discharges (flows out) the washed mud to the outside of the mud removing device. That is, the object of the present invention is to prevent the washed mud from accumulating at the lower part of the mud removing device and to efficiently discharge the mud from below the mud removing device to the outside so that the treatment is easy.

[0024] It should be noted that the embodiments described below are preferred specific examples of the present invention, and thus are technically limited in various ways. However, the scope of the present invention is not limited to these embodiments unless otherwise specifically limited in the following description.

[0025] <First Embodiment> As shown in FIG. 1, the wet earth discharging device 10 in the present embodiment has a mud receiving area 1 for receiving a cleaning liquid containing foreign matters such as mud and small stones falling from the mud removing device. The mud receiving area 1 of the wet soil discharging device 10 slopes downward in one direction toward the outer edge 11. The gradient angle θ1 at which the mud receiving area 1 slopes depends on the height of the location where the wet soil discharging device 10 is installed (the distance between the lower surface of the soil dropping device and the ground) and the distance flowing in the inclined direction (the length of the mud receiving area 1 in the inclined direction). As shown in Fig. 2, for example, if a gradient of about 3 to 4° is obtained with respect to the ground surface G, the cleaning liquid containing mud can be made to flow easily.

[0026] Also, in the present embodiment, the mud receiving area 1 has a concave shape that is recessed upward along the inclined direction. Specifically, the mud receiving area 1 has a V-shaped cross section with two flat slopes facing each other with the inclined direction as the axis. The gradient angles θ2 of the two slopes, similar to the gradient angle θ1 of the mud receiving area 1, depend on the height of the location where the wet soil discharging device 10 is installed (the distance between the lower surface of the soil dropping device and the ground) and the range for receiving the cleaning liquid containing mud. As shown in Fig. 3, for example, if each slope has a gradient of about 18° with respect to the ground surface G, the cleaning liquid containing mud can flow out more efficiently.

[0027] When the mud receiving area 1 is concave in this way, the cleaning liquid containing the mud falling from above can be collected in the concave area and efficiently discharged outward from the outer edge 11 of the mud receiving area 1. Also, when the mud receiving area 1 has a V-shaped cross section, the cleaning liquid containing the mud falling from above can be collected at the valley-shaped bottom 12 of the mud receiving area 1 without weakening the momentum. Also, even if the cleaning liquid has the same amount of water, the water level can be raised and the cleaning liquid containing mud can be efficiently discharged to the outer edge 11 of the mud receiving area 1.

[0028] That is, the lower position side of the inclined mud receiving area 1 becomes the outer edge 11 of the mud receiving area 1 where the cleaning liquid containing mud flows down. As shown by the dotted arrow on the mud receiving area 1 in Fig. 1, the cleaning liquid containing mud flows along the two flat slopes toward the valley-shaped bottom 12 on the lower position side and also flows toward the inclined outer edge 11. Note that the cleaning liquid refers to a liquid medium such as water or cleaning water containing cleaning components that washes away mud and the like adhering to the tires, bottom surface, and side surfaces of construction vehicles.

[0029] Further, it is desirable that the mud receiving area 1 has a rounded bottom 12. That is, the portion where the low-position sides of the two slopes meet is rounded without being sharpened. When the bottom 12 is rounded in this way, the width on the bottom 12 side is expanded, so that the mud (solid content) sinks deeply into the cleaning liquid in the mud receiving area 1, and the discharge efficiency of the mud can be improved.

[0030] That is, the small stones adhering to the tires of construction vehicles such as dump trucks at the site are generally about 2 to 4 cm, and although it depends on the shape, if the height of the small stones is high, they tend to be difficult to flow. However, by rounding the bottom 12 of the mud receiving area 1, as shown in the right figure in FIG. 4, the small stones S sink deeply into the cleaning liquid W. Then, the pressing force due to the flow of the cleaning liquid increases, and even large mud such as small stones can be efficiently discharged outward from the outer edge portion 11 of the mud receiving area 1.

[0031] FIG. 4 illustrates the advantages by comparing the shapes of the bottoms 12 of the mud receiving areas 1. On the left side, a state where small stones S exist in the V-shaped mud receiving area 1 with a pointed bottom 12 is shown, and on the right side, a state where small stones S exist in the V-shaped mud receiving area 1 with a rounded bottom 12 is shown. In FIG. 4, it is shown that the one with the rounded bottom 12 is lower by a height t than the one with the pointed bottom 12. Therefore, when the cleaning liquid W is at the same height, the small stones S sink deeper into the cleaning liquid W in the case of the one with the rounded bottom 12.

[0032] This mud receiving area 1 is configured, for example, by bending a metal plate into a V shape, molding a synthetic resin into a V shape, assembling wood into a V shape, or hanging a cloth or resin sheet material in a V shape. In addition, it is desirable that the soil receiving area 1 is approximately equal to or larger than the area of the region where the soil removal roller for removing soil from a tire or the like is installed in the soil removal device.

[0033] Note that the wet soil discharging device 10 in the present embodiment is provided with a plurality of wheels 5··5. The wheels 5 are movable means for facilitating the movement of the installation location, and are the same as those referred to as tires or casters. By providing such movable means, it is possible to easily perform the operation of pushing the wet soil discharging device 101 under the low-height soil removal device for installation and pulling it out.

[0034] As described above, the wet soil discharging device 10 of the present invention can reuse the cleaning liquid used when removing soil from a tire or the like with the soil removal device, and efficiently discharge the soil washed off from the soil removal device outward from the outer edge portion 11 of the soil receiving area 1. That is, the wet soil discharging device 10 can avoid the situation where the soil washed off by the soil removal device disposed above accumulates on the ground below the soil removal device.

[0035] Therefore, the time and labor for treating the washed-off soil can be shortened. Moreover, the washed-off soil can be visually confirmed clearly, so it is easy to collect and dispose of.

[0036] <Second Embodiment> In addition, in the invention, the inclination angle of the soil receiving area can be increased so that the washed-off soil can flow out to the outer edge portion of the soil receiving area more efficiently. That is, it is different from the above-described first embodiment in that a plurality of inclination directions toward the outer edge portion of the soil receiving area are provided instead of one direction.

[0037] In addition, in each of the other embodiments described below, the description will focus on the parts that are different from the above-described first embodiment. Therefore, the constituent parts that are the same as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted, and it is assumed that they are the same unless otherwise specified.

[0038] As shown in FIG. 5, in the wet soil discharging device 20 according to the present embodiment, the soil receiving area 2 is inclined downward in two separating directions. That is, in this soil receiving area 2, the vicinity of the center in the inclined direction is the highest position, and it is inclined downward to the outer edge portions 21, 21 in two directions separating from here.

[0039] Further, in the present embodiment, the soil receiving area 2 has a concave shape that is recessed upward along the inclined direction, and has a V-shaped cross section with two flat slopes facing each other with the inclined direction as the axis.

[0040] By providing a plurality of inclined directions toward the outer edge portion 21 of the soil receiving area 2 in this way, the cleaning liquid containing the soil falling from above can be efficiently separated into respective directions and discharged outward from the outer edge portion 11 of the soil receiving area 2. Moreover, compared with the case of inclining downward in one direction, the gradient angle of the inclination of the soil receiving area 2 can be increased, so that the cleaning liquid containing the soil can be more efficiently discharged from the soil receiving area 2 to the outer edge portion 21. Note that, in FIG. 5, the dotted arrows shown on the soil receiving area 2 indicate the flow of the cleaning liquid containing the soil toward the outer edge portions 21, 21 in two separating directions.

[0041] Therefore, the wet soil discharging device 20 of the present embodiment is effective when the height below the soil dropping device is low and a sufficient gradient angle cannot be obtained in the case where the inclined direction toward the outer edge portion of the soil receiving area is in one direction.

[0042] <Third Embodiment> In addition, in the invention, the configuration of the soil receiving area can be made simple, and the washed soil can be quickly discharged to the outer edge portion of the soil receiving area. That is, it is different from the above-described first embodiment in that the shape of the mud receiving area is not concave but flat.

[0043] As shown in FIG. 6, in the wet soil discharging device 30 according to the present embodiment, the mud receiving area 3 has a flat plane. In addition, in the present embodiment, the mud receiving area 3 further has an overflow prevention area 4 that prevents the mud from overflowing from the outer edge of the mud receiving area 3.

[0044] In FIG. 6, the overflow prevention areas 4 are shown as being formed at the outer edges at positions facing each other with the mud receiving area 3 interposed therebetween. At this time, the mud receiving area 3 is inclined toward the outer edge 31 where the overflow prevention area 4 is not formed.

[0045] In this way, when the mud receiving area 3 is a flat plane, the cleaning liquid containing the mud that has fallen from above does not gather near the center of the mud receiving area 3 at one end, but after being received by the mud receiving area 3, the cleaning liquid containing the mud can quickly flow out to the outer edge 31 of the mud receiving area 3. Therefore, in the wet soil discharging device 30 according to the present embodiment, when the height below the soil device is high and the gradient angle of the inclination toward the outer edge of the mud receiving area is sufficient, the discharge efficiency of the mud is increased and it becomes more effective.

[0046] In addition, by providing the overflow prevention areas 4 at the outer edges at positions facing each other with the mud receiving area 3 interposed therebetween, the cleaning liquid containing the mud will flow down toward the outer edge 31 where the overflow prevention area 4 is not formed, making it easier to recover the mud. The dotted line arrow shown on the mud receiving area 3 in FIG. 6 indicates the flow of the cleaning liquid containing the mud toward the outer edge 31 where the overflow prevention area 4 is not formed.

[0047] Although not shown, in the above-described wet soil discharging device 30 as well, the mud receiving area 3 may be inclined downward in two separating directions as in the second embodiment. Furthermore, as shown in FIG. 7, the mud receiving area 3 in the third embodiment may have a rounded bottom 32. That is, it may have a structure intermediate between the V-shaped cross-section of the mud receiving area in the first embodiment described above and the flat plane of the mud receiving area in the third embodiment. When the bottom 32 is rounded in this way, the mud (solid matter) will sink into the cleaning liquid, and the discharge efficiency of the mud can be improved.

[0048] <Other Embodiments> In the wet earth discharging devices 10, 20, and 30 described above, it is desirable that the mud receiving areas 1, 2, and 3 are formed of a material with low sliding resistance. That is, if the sliding resistance of the mud receiving areas 1, 2, and 3 is low, it is possible to eliminate the possibility that large mud such as small stones will remain in the mud receiving area and efficiently let it flow out to the outer edge of the mud receiving area.

[0049] Having a low sliding resistance (value) means that the friction (coefficient) is small, it has excellent slidability, is easy to slide, has been treated, or is formed of such a material, and it is intended that there are few irregularities on the mud receiving areas 1, 2, and 3 and the surface is smooth.

[0050] Also, in the wet earth discharging devices 10, 20, and 30, although not shown in the drawings, it may be provided with cleaning liquid supply means for injecting the cleaning liquid toward the mud receiving area 1. The cleaning liquid supply means may be configured, for example, by including a tank for storing a predetermined amount of cleaning liquid, a pump for supplying the cleaning liquid from this tank, a nozzle for injecting the cleaning liquid toward the mud receiving area, and a cleaning liquid supply path for sending the cleaning liquid supplied from the pump to the nozzle.

[0051] When the wet earth discharging devices 10, 20, and 30 are each provided with cleaning liquid supply means in this way, even if mud such as small stones remains in the mud receiving areas 1, 2, and 3 without flowing out together with the cleaning liquid, it can be surely made to flow out by the cleaning liquid injected from the cleaning liquid supply means.

[0052] Furthermore, in the wet soil discharging devices 10, 20, and 30 described above, although not shown in the drawings, they may be configured to include vibration applying means for applying vibration to the soil receiving areas 1, 2, and 3. The vibration applying means is a device that applies vibration by hitting the members forming the soil receiving areas 1, 2, and 3. For example, a vibrator or an actuator can be used. When the wet soil discharging devices 10, 20, and 30 are provided with the vibration applying means in this way, soil such as small stones can move downward efficiently in the soil receiving areas 1, 2, and 3, and the cleaning liquid containing soil can flow out more efficiently.

[0053] Also, the wet soil discharging devices 10, 20, and 30 may be directly installed on the soil dropping device 100, and the vibration generated during the soil dropping operation of the soil dropping device 100 may be utilized to act on the falling of the soil. The installation structure when directly installing the wet soil discharging device on the soil dropping device only needs to be such that the vibration of the soil dropping device is transmitted to the wet soil discharging device. For example, various installation structures can be adopted, such as welding the wet soil discharging device to the soil dropping device for installation, or using a rail structure, a suspension structure, a hanging structure for detachable installation, etc. Regarding the installation part of the wet soil discharging device on the soil dropping device, in addition to using the entire wet soil discharging device, it may also be configured such that only the high-position side of the wet soil discharging device is used as the installation part and the low-position side is grounded to the ground surface G.

[0054] The wet soil discharging device 10 (20, 30) configured as described above is installed below the soil dropping device 100 as shown in FIG. 8. Specifically, assuming that the direction indicated by the white arrow in the figure is the entry direction of the construction vehicle into the soil dropping device 100, the outer edge portions 11 (21, 31) of the wet soil discharging devices 10 (20, 30) are installed downward of the soil dropping device 100 with the left and right sides facing outward so that the cleaning liquid containing soil flows out (is discharged) to the left and right outside of this construction vehicle.

[0055] In FIG. 8, the wet earth removal device 10 (20, 30) is shown as being installed respectively below three locations: the front wheel earth removal roller 101, the rear wheel pre-earth removal roller 102, and the rear wheel post-earth removal roller 103, which are provided on the earth removal device 100. That is, it is shown that one wet earth removal device 10 (20, 30) is installed for each earth removal roller. Note that the wet earth removal device 10 (20, 30) can be used to act on the falling of the soil by utilizing the vibration generated during the earth removal operation of the earth removal device 100 by being directly installed on the earth removal device 100 as described above.
