At both ends of the scraper 55, a predetermined locking pin is inserted to prevent the scraper 55 from falling off. The cross-sectional shape of the scraper 55 is not limited to a circular shape, and may be, for example, a semicircular shape having a front lowering surface. Further, the number of scrapers 55 may be one or three or more, and they may be arranged side by side or diagonally instead of vertically.

  Each keel 54 and scraper 55 is set so as to sink in an appropriate amount in the sand, and when the second beach cleaner 50 runs in this state, each keel 54 scrapes sand and garbage and each scraper 55 scrapes them. As a result, the sand and dust rolled up in the net 56 at the rear of the frame 53 are thrown in.

With reference to FIGS. 9 and 10, a towing portion 67 for towing the second beach cleaner 50 with the vehicle 1 is provided in front of the second scraper frame 58 from the left and right outer ends of the frame 53. The pulling portion 67 is a thick plate that is orthogonal to the left-right direction, and is formed with a plurality of (for example, four) connecting holes 67a arranged vertically. One of these connection holes 67a is connected to the other end of the traction rod 38, one end of which is connected to the trailer hitch 11 of the vehicle 1, and the second beach cleaner 50 is connected to the vehicle 1 via the traction rod 38. (See FIG. 18).
At this time, it is possible to set an optimum traction position according to the ground height of the second beach cleaner 50 depending on which of the connection holes 67a the other end of the traction rod 38 is connected to. The left-right distance between the left and right traction parts 67 is substantially the same as the left-right distance between the left and right traction parts 37.

  A front ski support pipe 72 that supports the front ski legs 71 is provided in front of the left and right outermost scraper frame 58 in the frame 53. The front ski support pipe 72 is made of, for example, a square steel pipe that vertically penetrates the front lateral member 52a, and the leg member 73 made of the same square steel pipe in the front ski leg 71 can be inserted and supported. The front ski leg 71 sets the ground height of the front part of the second beach cleaner 50 (the height from the upper surface of the sandy surface) to a predetermined height and enhances the sliding property with respect to the sandy land. A leg member 73 is erected on a front ski board 74 having a width.

  The front ski support pipe 72 is formed with left and right through holes 72a, and a plurality of (for example, four) left and right through holes 73a corresponding to the left and right through holes 72a are formed vertically on the leg member 73. Is overlapped with the left and right through holes 72a of the front ski support pipe 72, and a predetermined locking pin or the like is inserted into these to determine the height of the front portion of the frame 53 with respect to the front ski leg 71. The ground height in front of the cleaner 50 is set to a predetermined height. That is, the ground height of the front portion of the second beach cleaner 50 can be adjusted by inserting the locking pin or the like into any of the left and right through holes 73a of the leg member 73, so that the keel 54 and the scraper 55 can enter the sand. The amount of subsidence can be adjusted.

  An extension frame 75 made of, for example, a square steel pipe extends rearward from both sides of the rear portion of the rear lateral member 52b, and a rear ski support pipe 77 that supports the rear ski leg 76 is supported at the rear end portion of each extension frame 75. Is provided. The rear ski support pipe 77 is made of, for example, a square steel pipe that penetrates the extension frame 75 in the vertical direction, and the leg member 78 made of the same square steel pipe in the rear ski leg 76 can be inserted and supported. The rear ski leg 76 has the same configuration and function as the front ski leg 71, and a leg member 78 is erected on the rear ski plate 79. The rear ski board 79 takes the case where the second beach cleaner 50 is loaded and unloaded along the left and right guide members 44 with respect to the loading portion 16 of the trailer 13 in the same manner as the first beach cleaner 20, and the rear portion is raised rearward (See FIG. 22).

  A single left and right through hole 77a is formed in the rear ski support pipe 77, and a plurality of (for example, four) right and left through holes 78a corresponding to the left and right through holes 77a are formed vertically on the leg member 78. The height of the rear portion of the frame 53 with respect to the rear ski leg 76 is determined by overlapping one of the through holes 78a on the left and right through holes 77a of the rear ski support pipe 77 and inserting predetermined locking pins or the like into these. The ground height of the rear part of the two beach cleaner 50 is set to a predetermined height (that is, the ground height of the rear part of the second beach cleaner 50 can be adjusted). The left and right width between the outer ends of the front ski plate 74 of the left and right front ski legs 71 is substantially the same as the left and right width of the frame 53, and the left and right width between the outer ends of the rear ski plates 79 of the left and right rear ski legs 76 is 53 is made narrower than the lateral width of 53.

  Front and rear lift arms 81a and 81b are provided on the left and right outer sides of the front and rear sides of the frame 53 so as to project from the outer end toward the left and right sides. Each of the lift arms 81a and 81b is a frame-shaped frame having a horizontally long shape when viewed from the top, for example. The left and right middle portions are substantially horizontal, the left and right inner portions are obliquely inward and the left and right outer portions are obliquely downward. Each bend is formed outward. The left and right width between the outer ends of the lift arms 81a and 81b is wider than the left and right width between the left and right side structures 41R and 41L of the dust collection station 40 (in other words, the frame 22 of the first beach cleaner 20). When the second beach cleaner 50 enters between the left and right side structures 41R and 41L, the lift arms 81a and 81b ride on the left and right side structures 41R and 41L. Thus, the second beach cleaner 50 is lifted up by a predetermined amount.

  When the second beach cleaner 50 is lifted up as described above at the garbage collection station 40, the net 56 at the rear of the frame 53 rises to a predetermined height, and the net 56 is rotated through the hinge 82 on the left side. By moving it (see FIG. 11), it becomes possible to easily collect the dust collected in the net 56. At this time, the trailer 13 is adjacent to the left side of the garbage collection station 40, and the garbage is directly put into the stacking portion 16 of the trailer 13.

  14 and 15 together, the rear lift arm 81b on the left side of the frame 53 is provided with a rear hinge bracket 83 that constitutes a part of a hinge 82 that rotatably supports the left side portion of the net 56. The rear hinge bracket 83 extends in the front-rear direction of the rear end side of the rear lift arm 81b, and has a front-rear wall 84 standing upward at the front-rear end, and a front end side of the front-rear wall 84 for the hinge shaft 82a. A front and rear through hole 84a is formed. A rear hinge pipe 85 provided on the left side of the mesh body 56 corresponding to the rear hinge bracket 83 is disposed between the front and rear walls 84, and the rear hinge pipe 85 is connected to the rear hinge bracket 82 via a hinge shaft 82a along the front and rear direction. 83 is rotatably supported by the shaft 83.

  Further, a frame-shaped support arm 86 having a lateral width reduced with respect to the lift arm 81b is provided slightly in front of the rear lift arm 81b. The support arm 86 has the same structure as that of the rear hinge bracket 83. A front hinge bracket 87 having a configuration is supported. The front and rear walls 88 of the front hinge bracket 87 are formed with front and rear through holes 88a for the hinge shaft 82a. A front hinge pipe 89 provided on the left side of the net 56 corresponding to the front hinge bracket 87 is disposed between the front and rear walls 88, and the front hinge pipe 89 is connected to the front hinge bracket via a hinge shaft 82a along the front and rear direction. 87 is rotatably supported. The hinge pipes 85 and 89 and the hinge shaft 82a are provided coaxially with each other.

  As shown in FIGS. 9 and 10, the net 56 has a box shape that opens forward and upward, and is formed by attaching a wire net having a mesh of a predetermined size to a frame type frame mainly composed of a steel pipe, for example. The net 56 is provided so as to have substantially the same left-right width as the frame 53 in the left-right direction from a position slightly forward of the front-rear center of the frame 53 to the vicinity of the rear end of the frame 53 in the front-rear direction. Here, the position of the front end of the net 56 is 100 to the rear from the vicinity of the rear end of each keel 54, that is, from the vicinity of each scraper 55, so that the sand and dust wound up by each keel 54 and the scraper 55 can be collected well. Separate about 300 mm. More preferably, the front end position of the net 56 is spaced apart from the vicinity of the rear end of each keel 54 by about 250 mm.

  Referring also to FIG. 11, the net 56 includes a bottom wall portion 92 having a horizontally long rectangular shape in a top view, a rear wall portion 93 rising substantially vertically from a rear edge of the bottom wall portion 92, and a bottom wall portion. The left and right side wall portions 94 rise up slightly inclined so as to be positioned on the left and right outer sides from the both side edges of 92. The rear wall portion 93 and the left and right side wall portions 94 open and surround the periphery of the bottom wall portion 92 only on the front side so that the dust rolled up by the keels 54 and the scraper 55 can be collected on the bottom wall portion 92. Form.

The front portion of the bottom wall portion 92 is an inclined portion 92a that is inclined slightly forwardly downward, and the portion that is behind the inclined portion 92a is an approximately horizontal horizontal portion. The horizontal portion is divided into a front horizontal portion 92b and a rear horizontal portion 92c with a horizontal member extending in the left-right direction as a boundary.
Here, a wire mesh having a mesh size of 25 mm is attached to the inclined portion 92a of the bottom wall portion 92, a wire mesh having a mesh size of 12 mm is attached to the front horizontal portion 92b, and a wire mesh having a mesh size of 8 mm is attached to the rear horizontal portion 92c. Is done.

  In this way, by setting the mesh size of the wire mesh of the bottom wall portion 92 as coarse as the front side, among the sand rolled up by each keel 54 and the scraper 55, sand containing relatively heavy moisture, etc. Since it does not reach the rear side of the 92, it is satisfactorily screened without causing clogging or the like through the coarse wire net in the inclined portion 92a on the front side of the bottom wall portion 92. On the other hand, the relatively light dry sand and the like reach the horizontal portion on the rear side of the bottom wall portion 92 together with the dust, and the sand and the like are screened through the middle and fine wire nets attached thereto. Good collection without dropping off the mesh. Each wire mesh can be appropriately replaced within a range of mesh sizes of 6, 8, 10, 12, 25 mm.

  The side wall portion 94 of the net 56 is formed with a rectangular side wall main body 94a that is long in the front-rear direction in the side view above the both side edges of the bottom wall portion 92, and has a trapezoidal shape in the side view above the rear side of the side wall main body 94a. A rear protrusion 94b is formed. The rear side portions of the side wall main body 94a and the rear projecting portion 94b are arranged in a straight line substantially perpendicular to the side view, and the rear wall portion 93 of the net 56 is provided with these rear side portions as side portions. The upper side part of the side wall part 94 (rear protrusion part 94b) and the upper side part of the rear wall part 93 are substantially the same height.

  Front and rear hinge plates 95a and 95b are provided in front of and behind the left side wall 94 of the net 56 so as to straddle the middle and lower frame members of the side wall body 94a. Each of the hinge plates 95a and 95b is a plate having a substantially square shape when viewed from the side. To form a reinforcing flange. Front and rear hinge pipes 85 and 89 are integrally joined to the outer surfaces of the hinge plates 95a and 95b, respectively.

  On the front upper side of the left and right side wall portions 94 (above the front hinge plate 95a in the left side wall portion 94), a handle 96a protruding upward from its upper edge is provided. The handle 96a has a U-shape that opens downward in a side view, and is inclined so that its upper side extends along the front-rear direction and projects slightly outward from the corresponding side wall 94. Further, on the upper left and right sides of the rear wall portion 93, a handle 96b protruding upward from the upper edge thereof is provided. The handle 96b has a U-shape that opens downward when viewed from the rear, and is provided substantially vertically so that its upper side extends along the left-right direction and is positioned substantially on the same plane as the rear wall 93.

  As described above, the left side portion of the mesh body 56 is rotatably connected to the left side portion of the frame 53 via the hinge 82, and the hinge 82 is lifted so that the right side of the mesh body 56 is lifted upward. If the net body 56 is rotated through the bottom wall portion 92 so that the bottom wall portion 92 is in an upright state, dust collected in the net body 56 falls on the left side wall portion 94, and the left side wall portion 94. The dust is discharged out of the net 56 along the way.

  At this time, by providing the handles 96a and 96b at each part (at least on the side opposite to the hinge 82) of the surrounding part 91 of the net 56, it is easy to collect dust by rotating the net 56. . Further, since the hinge 82 is arranged on one short side (left side) of the horizontally long net 56, the operation unit (right handle 96a, The length up to 96b) is ensured, and the rotation of the net 56 is facilitated.

  The left side wall portion 94 of the mesh body 56 (in other words, the wall portion on the hinge 82 side of the enclosure portion 91) is a wall portion on which a plate member is mounted in order to favorably discharge the dust. The upper edge portion of the left side wall 94 of the net 56 is set so as to protrude leftward from the left side structure 41L of the dust collection station 40 in the standing state (see FIG. 11). The garbage collected in the net 56 is directly thrown into the loading portion 16 of the trailer 13 adjacent to the left side of the 40 with the left side wall portion 94 as a slope. Note that the right side wall portion 94 and the rear wall portion 93 of the net body 56 are, for example, net portions to which coarse metal nets are attached in order to prevent the dust thrown into the net body 56 from dropping off.

  On the left and right vertical members 51 in the frame 53, left and right front ends or rear end stoppers 97a and 97b for positioning the front and rear ends of the net 56 on both left and right sides are provided. Each stopper 97a, 97b has a substantially vertical position restricting surface that contacts the front end or the rear end of the mesh body 56, and a rotation guide surface that is inclined upwardly and continuously above it. The member 51 is detachably attached.

  The position restricting surface of the left and right front end stopper 97a is in contact with both sides of the front end of the net 56 in use (a state where the bottom wall portion 92 is substantially horizontal and is in contact with the frame 53). The rear end side of the net 56 in use is in contact with the position restricting surface 97b, so that the net 56 is positioned in the front-rear direction with respect to the frame. Further, when the mesh body 56 is rotated to return from the standing state to the use state, both the front and rear ends are guided by the guide surfaces of the stoppers 97a and 97b, and the mesh body 56 is placed at a predetermined position on the frame 53. Returned to smooth. It should be noted that the positions where the stoppers 97a and 97b are attached to the vertical member 51 can be moved back and forth, and the net 56 can be moved back and forth.

Next, an outline of a procedure for cleaning the sandy beach using each of the beach cleaners 20 and 50 will be described.
First, as shown in FIGS. 1 and 19, the beach cleaners 20 and 50 and the garbage collection station 40 are loaded on the trailer 13 and transported to a predetermined cleaning work place. Here, the beach cleaners 20 and 50 are loaded on the trailer 13 in an assembled state, while the garbage collection station 40 includes left and right front and rear divided bodies 41a and 41b, a right intermediate divided body 41d, and front and rear connected parts. It is loaded on the trailer 13 in a state of being divided into the member 42 and each foot member 45.

  More specifically, first, a set of front and rear divided bodies 41a and 41b (or a set of front or rear divided bodies) are placed on the trailer 13 (accommodated in the loading section 16), and then each beach cleaner 20, 50 is placed. Is placed on the trailer 13. At this time, the first beach cleaner 20 has both side portions of the front and rear lateral members 24a and 24b of the frame 22 to the left and right side portions 16b and 16c of the stacking portion 16 (upper side portion 44c of the guide member 44 of the dust collection station 40). Since the sand pins 23 on both sides of the last row are in contact with the outer surface of the wheel house 16a of the stacking portion 16 from the front, the rearward movement of the first beach cleaner 20 is restricted ( FIG. 20).

  The second beach cleaner 50 is loaded with the vertical member 51 of the frame 53 placed on the front and rear horizontal members 24a and 24b of the first beach cleaner 20 in the loaded state and inclined slightly downward. Each keel 54 comes into contact with the front lateral member 24a of the first beach cleaner 20 from the front, whereby the rearward movement of the second beach cleaner 50 is restricted (see FIG. 20).

  In the garbage collection station 40, another set of front and rear divided bodies 41a and 41b (or a set of front or rear divided bodies) and a right intermediate divided body 41d are arranged in front of the second beach cleaner 50 in the loaded state. It mounts so that it may overlap with the part inclination part 57 and the scraper frame 58. Further, each connecting member 42 is mounted, for example, on the right side of the stacking unit 16 in a front-down state, and each foot member 45 is accommodated, for example, on the left rear side of the stacking unit 16.

  Note that the loading state of the garbage collection station 40 is not limited to the above-described one. For example, as shown in FIGS. 20 and 21, the front side inclined portion 57 and the scraper frame 58 of the second beach cleaner 50 in the loading state are disposed above. Only the right intermediate divided body 41d is mounted, for example, a pair of front and rear divided bodies 41a and 41b are mounted so as to be arranged in the left-right direction behind the second beach cleaner 50, and another set of front and rear divided bodies 41a and 41a, 41 b may be mounted in the stacking unit 16. At this time, the foot members 45 are housed by being appropriately distributed on the left and right of the rear portion of the stacking portion 16.

  Next, the beach cleaners 20 and 50 in the loaded state are lowered to the ground. At this time, by connecting the rear divided body 41b to the left and right side portions 16b and 16c of the loading portion 16 of the trailer 13, the loading and unloading work state is established (see FIGS. 22 and 23), and the loading state is achieved along the left and right guide members 44. Each of the beach cleaners 20 and 50 is lowered to the ground (see FIGS. 5 and 22), and even when they are assembled together, the beach cleaners 20 and 50 are lowered to the ground relatively easily. And can quickly move to the garbage collection operation.

  Next, the garbage collection station 40 is installed at a predetermined position on the sand beach. First, one rear division body 41b is removed from the left side portion 16b of the loading portion 16 of the trailer 13 in the unloading work state, and the rear division body 41b, the right intermediate division body 41d, and the front division body 41a are removed. The right side structure 41R is configured by coupling. On the other hand, the left side structure 41L is configured by connecting the front divided body 41a to the right side 16c of the stacking portion 16 of the trailer 13.

  The left and right side structures 41R and 41L are connected via the front and rear connecting members 42, and the foot recovery members 40 are assembled as the installation state by attaching the foot members 45 to predetermined positions. At this time, by loading the relatively large garbage collection station 40 on the loading unit 16 in a state of being divided into a plurality of divided bodies, the loading and unloading work on the trailer 13 of the garbage collection station 40 can be facilitated. .

  Next, the first beach cleaner 20 is pulled by the vehicle 1 and travels on the sand beach at a constant speed, thereby collecting relatively large garbage on the sand beach. The traveling locus of the vehicle 1 and the first beach cleaner 20 at this time is, as shown in FIG. 16, moving the turning position while turning in a substantially square shape within a predetermined range on the sand surface. It can be surely cleaned without unevenness. Since the first beach cleaner 20 collects relatively large garbage on the sand beach while each sand pin 23 is biting into the sand, the running resistance is relatively large, and the running speed is as low as about 5 to 10 km / h. Is set.

  As described above, when the first beach cleaner 20 travels on the sand beach and a predetermined amount of garbage is collected under the frame 22, the first beach cleaner 20 returns to the garbage collection station 40 and collects the collected garbage. Work is done. At this time, when the first beach cleaner 20 enters between the left and right side structures 41R and 41L after the vehicle 1 passes between the left and right structures 41R and 41L of the garbage collection station 40, the left and right sides of the frame 22 are moved. Rides on the left and right side structures 41R and 41L, and the first beach cleaner 20 is lifted up by a predetermined amount (see FIG. 5). Then, the vehicle 1 and the first beach cleaner 20 are stopped and dropped onto the sand surface with the first beach cleaner 20 riding on the upper sides 44c of the guide members 44 of the left and right side structures 41R and 41L. After performing the dust collection operation, the vehicle 1 and the first beach cleaner 20 are run again to repeat the above-described dust collection operation.

  After the predetermined range of cleaning is performed by the first beach cleaner 20, the second beach cleaner 50 is pulled to the same range to collect relatively small dust on the sand beach. Thus, by using the second beach cleaner 50 after the first beach cleaner 20, damage to the keel 54, the scraper 55, the net 56, and the like corresponding to fine dust can be suppressed. The traveling locus of the second beach cleaner 50 is the same as that of the first beach cleaner 20. Further, the second beach cleaner 50 is softened by digging up the sandy beach by the action of the first beach cleaner 20 during traveling, and it is necessary to wind up sand and dust by each keel 54 and scraper 55. The traveling speed is set to 15 to 25 km / h, which is slightly faster than the first beach cleaner 20.

  As the second beach cleaner 50 runs on the sandy beach, relatively small dust is rolled up by the keels 54 and the scraper 55 together with the sand, and these are collected in the net 56 at the rear of the frame 53. At this time, since the mesh size of the wire mesh is set to become smaller in order from the front side of the bottom wall portion 92 of the mesh body 56, collected dust is difficult to fall and clogging of the wire mesh is suppressed.

  As described above, when the second beach cleaner 50 travels on the sand beach and a predetermined amount of garbage is collected in the net 56, the second beach cleaner 50 returns to the garbage collection station 40, and the collected garbage is collected. Collection work is performed. At this time, when the second beach cleaner 50 enters between the left and right side structures 41R and 41L after the vehicle 1 passes between the left and right structures 41R and 41L of the garbage collection station 40, the left and right lift arms 81a before and after the second beach cleaner 50 enter. , 81b ride on the left and right side structures 41R, 41L, and the second beach cleaner 50 is lifted up by a predetermined amount (see FIG. 22). Then, with the second beach cleaner 50 riding on the upper sides 44c of the guide members 44 of the left and right side structures 41R and 41L, the vehicle 1 and the second beach cleaner 50 are stopped and the net 56 is rotated. After collecting the collected dust, the vehicle 1 and the second beach cleaner 50 are run again to repeat the above-described dust collecting operation.

  Here, as shown in FIG. 11, when collecting the dust collected by rotating the net 56, the loading unit 16 of the trailer 13 adjacent to the left side of the dust collection station 40 is in contact with the loading unit 16. Since the trash is directly thrown in, the loading unit 16 can be used as a trash collection container, and after the cleaning operation is completed, the collected trash can be transported by the trailer 13 and the collection work of the trash that has fallen to the ground is unnecessary. Therefore, the number of cleaning work steps can be reduced.

  As described above, the beach cleaner garbage collection station structure in the above embodiment collects the collected garbage by riding the beach cleaners 20 and 50 that are towed by the towing vehicle 1 and run on the sand to collect the garbage. In the structure of the garbage collection station 40 that can be made, the garbage collection station 40 is provided with a mountain-shaped guide member 44 on which the beach cleaners 20 and 50 are mounted on the grounding member 43 to form trapezoidal side structures 41R and 41L. The stacking portion 16 of the trailer 13 in the towed state constitutes at least the upper side portion 44c of the side structure bodies 41R and 41L.

According to this configuration, when the beach cleaners 20 and 50 and the garbage collection station 40 loaded on the loading unit 16 of the trailer 13 in the towed state are lowered to the ground, the loading unit 16 is first included at a predetermined position. After the dust collection station 40 is set in an installed state or the like, the beach cleaners 20 and 50 on the stacking unit 16 can be lowered to the ground along the guide member 44 of the dust collection station 40. Further, when the beach cleaners 20 and 50 and the garbage collection station 40 are loaded on the loading unit 16, the beach cleaners 20 and 50 are first lifted up along the guide member 44 of the dust collection station 40, and this is loaded into the loading unit. After loading on 16, the garbage collection station 40 can be disassembled and loaded on the loading unit 16.
As described above, the loading unit 16 of the trailer 13 in the towed state constitutes a part of the guide member 44 of the garbage collection station 40, so that the beach cleaners 20 and 50 and the garbage collection station 40 can be easily loaded and unloaded from the trailer 13. Thus, man-hours can be reduced.

  Moreover, in the said garbage collection station structure, the said side part structure 41R, 41L is comprised by the some division body which can respectively be attached or detached from each other, and the trailer 13 which is in the said tow | pulling state at least one of each said division body is provided. By configuring, the garbage collection station 40 can be disassembled into a plurality of divided bodies, and the trailer 13 can be loaded and unloaded, and the loading and unloading work can be facilitated.

  Further, in the dust collection station structure, the dust collection station 40 has a pair of left and right side structures 41R and 41L, and pulls at least the upper side 44c of the right side structure 41R among them. Since the stacking portion 16 of the trailer 13 in the state is configured, the garbage collection station 40 can be installed with the trailer 13 being adjacent to the right side structure 41R side, so that the installation work can be facilitated.

  Furthermore, in the garbage collection station structure, the second beach cleaner 50 has a net 56 for collecting garbage, the net 56 is rotatably provided, and a rotation shaft of the net 56 is provided. The (hinge shaft 82a) is located on the right side structure 41R side when the second beach cleaner 50 rides on the garbage collection station 40, and the trailer 13 is placed on the right side structure 41R on the rotating shaft side. The garbage collection station 40 is installed so as to be adjacent to each other, so that the collected dust can be discharged by rotating the mesh body 56, and the second beach cleaner 50 is lifted up by the garbage collection station 40 and the garbage is collected. By performing the discharge operation, the garbage can be directly put into the loading section 16 of the trailer 13 adjacent to the right side structure 41R on the rotating shaft side. Together and can be utilized, can be made unnecessary waste recovery operations from the sand, it can be a waste recovery work easily with.

  Moreover, in the dust collection station structure, the dust collection station 40 includes a connecting member 42 that connects the pair of left and right side structures 41R and 41L, and the connecting member 42 includes each side structure.
