BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of self-propelled environmental recycling machines such as self-propelled crushers, self-propelled soil improvement machines, and wood-based self-propelled tab gliders.
[0002]
[Prior art]
In recent years, self-propelled environmental recycling machines such as self-propelled crushers, self-propelled soil improvement machines, and wood-based self-propelled tab gliders that are equipped with a working device such as a crushing device and a stirring device on a vehicle body equipped with a traveling body However, when working with such a self-propelled environmental recycling machine, there is a risk that fine dust will soar in the air, leading to deterioration of the work environment and surrounding environment.
Therefore, in order to prevent dust scattering, the self-propelled environmental recycling machine is provided with a watering device for spraying water to a place where dust is generated, such as an inlet portion of the crushing device, or to a crushed material. Such a watering device requires a water source for supplying water to the watering device, but there are many sites where tap water cannot be secured as a water source at the work site, and there have been conventional self-propelled environmental recycling machines. There is known a structure in which a water tank is mounted on the vehicle body, and water in the water tank is sucked with a pump and supplied to a watering device (for example, see Patent Document 1).

[Problems to be solved by the invention]
By the way, since the said conventional thing uses the water tank as a water source, when this water tank becomes empty, the water supply to a water tank is needed. On the other hand, there is a case where tap water can be secured at the work site. In this case, tap water is used as a water source, so that it is not necessary to mount a water tank on the vehicle body, and it is not necessary to supply water to the water tank. However, the conventional one has a problem that even if it is a site where tap water can be secured, since there is no supply means for supplying water from the tap water to the watering device, tap water cannot be used effectively. There was a problem to be solved by the present invention.
Moreover, in the said conventional thing, the water tank is distribute | arranged in the state which protrudes further back from the rear-end part of a vehicle body. For this reason, there also existed the problem which should be solved that the full length of a vehicle body will become long.

In this case, the water tank device 15 is configured so that the water tank device 15 has a space below the rear half of the hopper 5 and the vibration feeder 6 (behind the side conveyor 8 disposed below the front half of the vibration feeder 6. In the space) without protruding rearward from the rear end portions of the hopper 5 and the vibration feeder 6 and without protruding from the left and right widths of the hopper 5 and the vibration feeder 6.
[0012]
When the crushing work is performed in the self-propelled crusher 1, when tap water cannot be used as a water source at the crushing work site, the water tank device 15 is mounted on the self-propelled crusher 1, and the water tank The hose 20 extending from the device 15 is connected to the tank water supply port 16c of the joint portion 16 of the watering device 14, while the water tap 16b is closed. When watering is performed, the tank cock 25 and the first and second valves 19X and 19Y are opened and the pump 22 is driven to discharge water from the first injection nozzle assembly 18X from the carry-out conveyor 13 to the outside. While being sprayed to the crushed material, the water from the second spray nozzle assembly 18Y is sprayed to the inlet 4a of the crushing device 4. When water is sprayed from only one of the injection nozzle assemblies 18X and 18Y, only one of the corresponding first and second valve valves 19X and 19Y may be opened.
Moreover, when drain drainage is performed in a state where the water tank device 15 is mounted on the self-propelled crusher 1, the first and second injection nozzle assemblies 18X and 18Y are closed with the water cock 16b closed. The plugs 18Xc and 18Yc for sealing are removed, the first and second valves 19X and 19Y are opened, and the drain port (not shown) of the pump 22 and the drain port (not shown) of the water tank 21 are opened. Drained.
[0013]
On the other hand, when tap water can be used as a water source at the crushing work site, it is not necessary to mount the water tank device 15 on the self-propelled crusher 1. While the tank water supply port 16c is sealed with a sealing plug, a hose extending from the water supply is connected to the water supply port 16a. When watering is performed, the water supply cock 16b is opened, and the first and second valves 19X and 19Y are opened, so that the first injection nozzle assembly 18X is used in the same manner as in the case where the water tank device 15 is used as the water source. Water from the carry-out conveyor 13 is sprayed onto the crushed material, and water from the second spray nozzle assembly 18Y is sprayed to the inlet 4a of the crushing device 4. In this case as well, when water is sprayed only from one of the injection nozzle assemblies 18X, 18Y, only one of the corresponding first and second valve valves 19X, 19Y may be opened.
Further, in this case, drain drainage removes the plugs 18Xc and 18Yc for sealing the first and second injection nozzle assemblies 18X and 18Y, opens the first and second valves 19X and 19Y, and opens the water cock 16b. Accordingly, drainage is drained from the water supply port 16a.
[0014]
In what is configured as described, the self-propelled crusher 1 is equipped with a water spray device 14 for preventing dust scattering, and the water spray device 14 includes a water supply port 16a connected to the water supply, And a tank water supply port 16 c connected to the water tank device 15. When tap water is used as the water source, water from the water supply can be supplied to the water sprinkler 14 by connecting the water supply to the water supply port 16a and closing the tank water supply port 16c with a sealing plug. When water from the water tank device 15 is used as a water source, the hose 20 extending from the water tank device 15 is connected to the tank water supply port 16c, while the water tap 16b is closed to Water can be supplied to the watering device 14. As a result, both tap water and the water tank device 15 can be used according to whether tap water can be secured at the crushing work site, which is excellent in convenience.
In the present embodiment, the water cock 16b and the tank cock 25 are separately provided as means for switching the water supply from the water or water tank 21 to the water sprinkler 14. However, the present invention is not limited to this. For example, it can also be set as the structure switched using a three-way cock.
[0015]
Further, in this device, the water tank device 15 is arranged in a space below the hopper 5 and the vibration feeder 6 disposed above the rear of the machine body so as to introduce the object to be crushed into the crushing device 4. And it is arranged in the upper and lower overlapping state which does not protrude from the left and right outer sides. For this reason, even if the water tank device 15 is mounted, the front-rear length and the left-right width of the self-propelled crusher 1 are not increased, and the self-propelled crusher 1 can be made compact, Effective use can be achieved.
In addition, the structure / system of the watering device of the present invention is not limited to the above-described self-propelled crusher, but also a self-propelled soil improvement machine (preventing scattering of earth and sand, solidified material), a wooden self-propelled tab grinder (wood chip It can also be applied to similar environmental recycling machines, such as wood powder scattering prevention), and in this case, the same effect can be provided.
