[Problems to be solved by the invention] However, since the shot blasting equipment configured as described above has a relatively large dust collector, the entire equipment becomes large and the place where it can enter is limited, and the processing range is limited. There was a problem. In addition, dust collected at the lower part of the dust collector is manually refilled in a disposal bag with a scoop, etc., but when refilling the dust, the dust soars around the worker and deteriorates the environment. There was also a problem. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a shot blasting facility that enables a relatively small size of a dust collector and facilitates transfer of dust to a waste bag. Aim.

[0004]

In order to achieve the above-mentioned object, a mobile shot blasting facility according to the present invention is configured such that a shot projecting device and a shot collecting case device including a shot collecting case main body are substantially V-shaped. Attached to a self-propelled device, a separation device for separating a shot and impurities from each other is disposed between a shot discharge port of the shot collection case device and a shot supply port of the shot projection device,
Further, a dust collecting device communicating with the separating device is mounted on the shot projecting device and the shot collecting case device to move on the processed surface and process the processed surface while collecting the projected shot. In the mobile shot blasting facility, the shot collecting case main body of the shot collecting case device is formed in a V-shape in vertical section, and the separation device is connected to a shot discharge port of the shot collecting case main body. A receiving shelf for temporarily receiving a shot or the like from the shot collecting case main body is provided below a connection position of the shot collecting case main body in the hopper, and near a shot discharge port of the shot collecting case main body in the hopper. Baffle plates are arranged at appropriate intervals in the cabinet of the dust collecting apparatus.

In the separating device 4, a receiving shelf 29 is provided below the connection position of the shot collecting case main body 20 inside the closed hopper 28, and a baffle plate 30 is provided on the right side of the receiving shelf 29. A vertical air passage 31 extending vertically and a horizontal air passage 32 extending horizontally are formed on the right side of the baffle plate 30 in the vicinity of the shot discharge port of the shot collection case main body 20. Wind path 3
A small hole 33 is formed at the right end of 2. In addition, hopper 2
A wire mesh 34 is stretched at a lower portion in the inside 8, and a lower end of the hopper 28 communicates with a shot supply port 2 a of the shot projecting device 2 via a damper 35.

In the dust collector 5, the interior of the cabinet 36 is divided into upper and lower chambers 36a and 36b by a partition plate 6, and the lower chamber 36b of the cabinet 36 communicates with the separating device 4 at an upper portion. A vertical air passage 37 is provided, which is directed to the upper surface 36a. A filter 38 communicating with an upper chamber 36a of the cabinet 36 is vertically provided on the lower surface of the partition plate 6, and the upper chamber 36a has an opening at the upper end of the filter 38. The facing compressed air ejection nozzles 39, 39 are provided,
On the left side of the cabinet 36, there is an upper chamber 36a.
And a blower 40 communicating with the cabinet 3
The lower part of 6 has a lower tapered shape, and a dust receiving container 42 in which a waste bag 41 is provided is detachably attached via a latch 45. Further, the nozzle 39 is connected to a compressor 43 with a storage tank disposed near the blower 40 via an on-off valve 44. In the drawing, reference numeral 46 denotes a control panel.

The operation of the facility having the above-described structure will be described. By driving the blower 40 of the dust collecting device 5, the shot collecting case main body 20 of the shot collecting case device 3 is
In a state where an upward airflow is generated, the motor 18 of the shot projecting apparatus 2 is driven to rotate the impeller 19, and the equipment is advanced in the direction of the arrow while projecting a shot. Then, the projected shot hits the surface to be processed C and rebounds, and together with the separated material separated from the surface to be processed C, is raised by the airflow flowing through the inside of the shot collection case main body 20 and lifted. The light is sequentially sucked into the separating device 4 and the dust collecting device 5 while being reflected on the wall surface formed in the shape.

[0012] Thus, when the shot or the like containing the separated material is sucked into the separation device 4 or the like, the shot or the like is first discharged from the upper end portion of the shot collection case main body 20 in the separation device 4 and directed downward to be placed on the receiving shelf 29. . The shots and the like that fall on the receiving shelf 29 because the receiving shelf 29 is full of shots and the like are removed by blowing up dust and the like by the airflow discharged from the upper part of the collection case 20,
Subsequently, the shots and the like that have not been removed are removed by moving up the vertical air path 37 of the dust collecting device 5. The shot thus removed falls and falls on the wire net 34 through the small holes 33, while the dust is removed by the filter 38. Also, shots that fall on the wire netting 34,
After flowing through this, large impurities are removed and then flow into the supply port of the shot projection device 2, while the dust separated from the filter 38 falls into the waste bag 41. Thus, when the inside of the waste bag 41 is full of dust or the like, the latch is loosened, the dust receiving container 42 is removed, and then the dust is removed from the dust receiving container 42 so that the dust can be easily removed from the equipment. Can be removed.

[0013]

As is apparent from the above description, in the present invention, since the shot collecting case main body is formed in the shape of a vertical cross section and the upper end of the shot collecting case main body communicates with the hopper of the separation device, the reflection is achieved. The shot that has been lifted while being removed can remove relatively large dust by the rising airflow discharged from the shot collecting case main body, and furthermore, is directed upward to the joint position of the dust collector cabinet with the separating device. Since the vertical air passage is formed, fine dust and the like can be removed. As a result, the dust collecting device can be reduced in size, and the processable range can be widened as compared with conventional equipment. In addition, since the dust container inside the waste bag is detachably attached to the lower part of the cabinet of the dust collector, there is an excellent practical effect that the dust does not soar up when the dust is taken out from the dust collector.
