Description

  Each invention of this application includes a self-propelled traveling body, a conveyor installed on the traveling body so as to carry an object to be sorted, and a worker performing a sorting operation provided on the side of the conveyor. The present invention relates to a self-propelled sorting device that includes a floor for placement, and sorts and sorts objects to be sorted conveyed by a conveyor.

  Conventionally, as a self-propelled sorting device, a self-propelled traveling body capable of traveling on a work site, and a belt that is installed on the traveling body and conveys an object to be sorted such as waste to be sorted. 2. Description of the Related Art There is known an apparatus including a conveyor such as a conveyor and a floor provided on both sides or one side of the conveyor and on which a worker who performs a sorting operation can be arranged. By adopting such a structure, this self-propelled sorting device sorts and sorts the items to be sorted by the conveyor manually by the workers placed on the floor beside the conveyor, and the waste, etc. Various useful resources that can be reused can be recovered from the selection items. A technique relating to this type of self-propelled sorting apparatus is described in Patent Document 1, for example.

  Here, the technology related to the mobile sorting conveyor car described in Patent Document 1 is positioned as a conventional technology, and the technical contents are outlined below. Further, a technical problem to be solved by the present invention will be mentioned later in relation to the technique described in Patent Document 1.

  A mobile sorting conveyor vehicle as a conventional self-propelled sorting device described in Patent Document 1 includes a towing vehicle as a self-propelled traveling body capable of traveling on a work site, and the towing vehicle. A movable sorting conveyor device that is connected and installed is provided. The towing vehicle is self-propelled by wheels, and has a connecting part for connecting the mobile sorting conveyor device to the rear part. In addition, the mobile separation conveyor device has a connecting part for connecting to the connecting part of the towing vehicle at the front part, and a loading platform having traveling wheels at the rear part, and is mounted on the loading platform in the front-rear direction. And a sorting conveyor for transporting waste as the object to be sorted.

  The upper surface of the loading platform on both sides or one side of the sorting conveyor is used as a floor for placing sorting workers (workers who perform sorting work), and each space for multiple sorting workers to ride is used. I try to secure it. For the separation conveyor, a type of conveyor such as a belt conveyor that conveys the object to be sorted is used. By this, the sorting worker looks at the conveyor and selects various materials from the object to be sorted. Can be visually identified and picked up. On the side of each floor for sorting workers, there is a means for discharging the sorting materials, such as a loading guide cylinder, for feeding the predetermined sorting items sorted by the sorting workers and leading them to predetermined locations outside the machine. It is attached.

  Since this conventional self-propelled sorting apparatus has such a structure, when the waste is carried into the rear part of the separation conveyor after being self-propelled and positioned at the waste sorting planned place, this waste Is conveyed forward by a separation conveyor, and a plurality of separation workers beside the conveyor share and sort out various useful resources from the waste. Each sorting worker inputs each of the selected items into the means for discharging the selected items by his / her own. As a result, various useful resources sorted out from the waste are sorted out.

In this conventional self-propelled sorting apparatus, since the sorting worker sorts the sorting objects manually, the sorting work is performed manually. For example, the sorting objects in which various materials such as construction waste materials are mixed. Even so, various useful resources can be appropriately selected and recovered. In addition, since the vehicle can run on its own, it can be easily positioned at a place convenient for sorting work by traveling on the work site and approaching the waste generation site and the collection site. Furthermore, since this self-propelled sorting device is pre-assembled as a mobile sorting conveyor device with ancillary equipment such as a sorting conveyor and a discharging means for the sorted matter, the conveyor and the accompanying equipment are located near the planned waste sorting place. It can be installed efficiently without the effort and time to carry and assemble.
JP 2003-145058 (page 2-4, FIG. 1-5)

  This conventional self-propelled sorting apparatus has such various advantages in use. However, it is necessary to be able to sort even to-be-sorted materials in which various materials such as construction waste are mixed. Since the method is used, the workers have to work long hours manually in the field, and the work burden on the workers is very large. For this reason, it is extremely important to make the worker's sorting work easier and reduce the work load on the worker, but the conventional self-propelled sorting device has little consideration for this. Has not been made. In this type of self-propelled sorting apparatus, there are a variety of items that need to be improved in order to make it easier for workers to perform sorting operations, but three typical items are mentioned below.

  First, the first matter to be improved will be described. In this sorting operation, a worker next to the conveyor picks up and sorts a predetermined sorting object from among the sorting objects on the conveyor while riding on the floor. This depends on the relative height of the floor with respect to the conveyor. Therefore, it is desirable that the relative height of the floor on which the worker rides with respect to the conveyor can be appropriately set so that the worker can perform the sorting operation as easily as possible. And, for example, if there is no big difference in the work conditions of each worker such as the type of sorting work and the height of the worker, the workers can make the sorting work as easy as possible for all the workers. It is desirable to appropriately set the height of the floor on which the car rides.

  On the other hand, depending on the type of sorting work assigned to the worker, the height of the worker, and the like, there may be a worker who is extremely difficult to perform the sorting work due to the height of the conveyor. For example, if some workers are responsible for sorting heavy labor to pick up heavy items and the relative height of the conveyor to the workers is too high to pick up heavy items, heavy items It becomes very difficult to pick up and put it into the discharging means for sorting items such as a guide cylinder for loading. Therefore, in such a case, the floor height relative to the conveyor should be reduced so that the relative height of the conveyor relative to the worker is lowered, giving priority to facilitating the work of the workers who share this heavy labor sorting work. It may be desirable to position the height higher, thereby making it easier to lift heavy objects.

  Also, if there is a worker with a particularly low height among the workers, if the height of the floor relative to the conveyor is set according to the height of the other workers, the worker with a short height will be able to perform sorting work. It becomes very difficult to do. Therefore, in such a case, the floor height with respect to the conveyor is positioned higher so that the relative height of the conveyor with respect to the worker is lowered, so that it is possible to select a worker with a short height. It may be desirable to avoid any disruption. For this reason, firstly, it is desired that the relative height of the floor with respect to the conveyor can be appropriately set as required to facilitate the worker's sorting operation.

  Next, the second matter to be improved will be described. Since the sorting operation with the self-propelled sorting device is usually carried out outdoors, depending on the conventional self-propelled sorting device, the worker is exposed to direct sunlight in fine weather and to rain in rainy weather. Become. And since such sorting work is usually done for a long time and may be done for several days, depending on the climatic conditions, it will place an excessive physical burden on the worker, and in some cases, It may harm the health of workers. For this reason, secondly, it is desirable to make it easier for workers to perform sorting operations by protecting workers from sunlight and rain and improving the working environment.

  Finally, the third item to be improved will be described. The conventional self-propelled sorting device continuously supplies a considerable amount of sorting objects from the carry-in side of the conveyor when sorting operations are performed, so that the sorting objects are always uniformly distributed on the conveyor and conveyed. Not necessarily. However, if the objects to be sorted are not uniformly distributed in the width direction on the conveyor but are transported in a certain place on the conveyor, the worker will remain in the objects to be sorted on the conveyor in this state. Therefore, it becomes difficult to distinguish a predetermined sorting object, and the sorting operation cannot be performed smoothly. For this reason, thirdly, when the objects to be sorted are transported by the conveyor during the sorting operation, the objects to be sorted are transported by being distributed in the width direction of the conveyor. It is desirable to do.

  Each invention of this application was created in response to each of these various requirements, and any of the technical problems of each of these inventions can make it easier for workers to perform sorting work than before. It is to provide a self-propelled sorting device.

  In order to achieve such a technical problem, the self-propelled sorting device according to the first invention of this application is configured as follows 1), and the self-propelled sorting device according to the second invention of this application. Then, it comprised as follows 2), and it comprised as the following 3) in the self-propelled sorter concerning the 3rd invention of this application.

2) A self-propelled traveling body capable of traveling on the work site, a conveyor that is installed on the traveling body and conveys the objects to be sorted, and both sides of the conveyor Provided on at least one side, and a floor on which workers for sorting work can be placed. Self-propelled sorting in which workers on the floor sort and sort the objects to be transported by the conveyor In the device
A worker protection cover that protects workers on the floor from sunshading or rain protection is provided so that they can be installed detachably.

3) A self-propelled traveling body capable of traveling on the work site, a conveyor that is installed on the traveling body and conveys the objects to be sorted, and both sides of the conveyor. Provided on at least one side, and a floor on which workers for sorting work can be placed. Self-propelled sorting in which workers on the floor sort and sort the objects to be transported by the conveyor In the device
A hopper that can input the objects to be sorted and can receive the objects to be sorted and guide them to the conveyor, and distributes the objects to be sorted to be distributed in the width direction of the conveyor. The sorting member is attached to the hopper.

  In the self-propelled sorting device according to the first invention of this application configured as described in 1) above, the floor vertical movement means is provided, and the vertical position of the floor moved by the vertical movement means is determined. Since it is configured so that it can be fixed, if necessary, the floor is moved up and down by means of moving the floor up and down to fix the vertical position of the floor, so that the relative height of the floor with respect to the conveyor is fixed. Can be adjusted. Therefore, when performing the sorting work, the sorting work is performed by adjusting the relative height of the floor with respect to the conveyor while considering the type of sorting work that each worker shares and the height of each worker. The height of the floor can be set so as to be as easy as possible for all the members, or the height of the floor can be set so that no worker who is extremely difficult to perform the sorting work is generated. As described above, according to the self-propelled sorting device according to the present invention, it is possible to facilitate the sorting operation of the worker by appropriately setting the relative height of the floor with respect to the conveyor.

  The self-propelled sorting apparatus according to the second invention of this application configured as described in 2) above is provided with a worker protection cover that acts as an awning or a rain shield for workers on the floor. Because it is configured so that it can be installed in a removable manner, this protective equipment can be exposed to direct sunlight or rain by installing the protective cover of this equipment in clear or rainy weather. Can be prevented. As described above, according to the self-propelled sorting apparatus according to the present invention, the worker can be easily sorted by protecting the worker from sunlight and rain and improving the working environment.

  In the self-propelled sorting apparatus according to the third invention of the present application configured as described in 3) above, a hopper capable of guiding an object to be sorted to the conveyor is installed in the traveling body, and a sorting member is disposed on the hopper. Since it is attached, it is possible to disperse the objects to be sorted into the conveyor in the width direction of the conveyor. As a result, the objects to be sorted placed on the conveyor are transported in such a way that the height is more uniform than in the past in the width direction of the conveyor without being solidified and transported to a specific location on the conveyor. As a result, the sorting operation for distinguishing a predetermined sorting object from the sorting objects on the conveyor can be performed more easily than in the past. As described above, according to the self-propelled sorting apparatus according to the present invention, when the sorting object is transported by the conveyor during the sorting operation, the sorting object is distributed and transported in the width direction of the conveyor. , Making it easier for workers to perform sorting operations. As described above, according to any of the first to third inventions of this application, it is possible to make the worker's selection work easier than before.

  As will be apparent from the following description, the self-propelled sorting device according to the first invention of this application is configured as shown in 1) in the above [Means for Solving the Problems]. Therefore, by appropriately setting the relative height of the floor with respect to the conveyor, it is possible to facilitate the operator's sorting operation. Since the self-propelled sorting device according to the second invention of this application is configured as shown in 2) of the same paragraph, it is intended to improve the working environment by protecting workers from sunlight and rain. Therefore, it is possible to facilitate the worker's sorting operation. Since the self-propelled sorting device according to the third invention of this application is configured as shown in 3) of the same paragraph, the sorting object is to be sorted when it is transported by the conveyor during the sorting operation. By distributing and transporting objects in the width direction of the conveyor, it is possible to facilitate the operator's sorting operation. As described above, according to any of the first to third inventions of this application, it is possible to make it easier for the operator to perform the sorting operation than before.

  When the self-propelled sorting device according to any one of the first to third inventions of this application is embodied, particularly when embodied as described in claim 4, an operator is selected during the sorting operation. By projecting a chute installed by the side so as to incline downward to the side of the traveling body, it is possible to throw in a sorted item and guide it outside the machine. As a result, the worker can perform the sorting operation with little movement, and thus the sorting operation can be performed efficiently. On the other hand, at the time of non-sorting work, the chute can be stored in the machine by raising the upper end side of the chute. Therefore, when the use of the chute is no longer necessary, the chute can be cleaned up by a simple operation so as not to narrow the effective space on the traveling body, and the space on the narrow traveling body can be used effectively and When running or transporting with a transport vehicle, you can avoid getting in the way.

  When embodying the self-propelled sorting device according to any of the first to third inventions of this application, in particular, if embodied as described in claim 5, the floor is moved in the left-right direction. Therefore, when performing a sorting operation, the floor is moved outward in the left-right direction by using the left-right direction moving means of the floor. An effective space can be expanded in the horizontal direction to secure a space for workers. Also, during non-sorting work, the lateral width of the self-propelled sorting device can be reduced so as not to obstruct the movement by moving the floor inward in the left-right direction using means for moving the floor in the left-right direction. The self-propelled sorting device can be smoothly run on the work site or transported by a transport vehicle such as a truck or trailer.

  In the following, each invention of this application will be implemented by explaining how the first, second and third inventions of this application are actually realized with reference to FIG. 1 to FIG. The desirable form to do is clarified.

  FIG. 1 is a side view of the self-propelled sorting apparatus according to the invention of the present application and shows a state when performing a sorting operation, FIG. 2 is a plan view of the self-propelled sorting apparatus of FIG. 1, and FIG. 1 is a rear view of the self-propelled sorting device of FIG. 1, FIG. 4 is a sectional view of the self-propelled sorting device of FIG. 1 cut along a sectional line A and viewed in the direction of the arrow, and FIG. FIG. 6 is a side view of the self-propelled sorting device according to the present invention of the present application, in which the self-propelled sorting device is transported. FIG. 7 is a plan view of the self-propelled sorting device of FIG. 6, FIG. 8 is a rear view of the self-propelled sorting device of FIG. 6, and FIG. 9 is a cross-sectional view of the self-propelled sorting device of FIG. 10 is a cross-sectional view of the self-propelled sorting device of FIG. 6 cut along a cross-sectional line B and viewed in the direction of the arrow.

  In the present specification, the front and rear and the left and right of the self-propelled sorting device are determined according to the description in Patent Document 1. That is, the traveling direction of the self-propelled sorting device is defined as the front-rear direction, and the forward side in this traveling direction is the front and the backward side is the rear. Therefore, the surface of the self-propelled sorting device viewed from the forward side in the traveling direction is the front surface, and the surface viewed from the backward side in the traveling direction is the back surface. Moreover, let the direction orthogonal to the running direction of a self-propelled conveyor apparatus be the left-right direction.

  First, the structure that forms the base of the self-propelled sorting apparatus, such as the structure related to the sorting apparatus such as the belt conveyor 10 and the hopper 11 and the self-propelled traveling body 1, will be described.

  1 to 10, reference numeral 1 denotes a self-propelled traveling body that runs on a crawler capable of traveling on a work site for various sorting operations, and 2 denotes a base of various devices installed on the traveling body 1. The first base frame 3 serves as a base, and also serves as a base. The second base frame is installed on the first base frame 2 so as to project rearward, and 4 is a first base frame. 3 is a third base frame that protrudes forward on 2, 5 is a frame for supporting a sorting device that is installed on the second base frame 3 at an interval, and 6 is a second base frame. Reference numeral 7 denotes an extension frame fixed to the rear end of the second base frame 3 so as to extend 3 backward, and a support column erected on the front end of the second base frame 3.

  Here, as the self-propelled traveling body, the traveling body 1 traveling by a crawler is shown, but the self-propelled traveling body may be a traveling body traveling by a wheel, and the type thereof is not limited. The first base frame 2 serves as a base for installing a power unit 8 and a driver's seat 9 which will be described later. The 2nd base frame 3 becomes a base for installing the sorting device comprised by providing the belt conveyor 10, the hopper 11, and the magnetic separator 12 mentioned later. The third base frame 4 serves as a base for installing the belt conveyor 10 in cooperation with the second base frame 3. These base frames 2, 3, 4 form an upper frame of the traveling body 1. The frame 5 for supporting the sorting device serves to support the sorting device, the floor 17 and the like that are configured by providing the belt conveyor 10, the hopper 11, and the magnetic separator 12. The sorting device support frame 5 is installed so that the rear side is supported by the extension frame 6 and the front end portion is supported by the support column 7 so that a space is provided on the second base frame 3.

  8 is a hydraulic pump for generating hydraulic pressure, an engine for driving the hydraulic pump, a hydraulic oil tank, a fuel tank, a power unit incorporating a control valve and the like, and 9 is a self-propelled type such as operating the traveling body 1 and the belt conveyor 10. A driver's seat 10 for maneuvering the sorting device is supported on the traveling body 1 and conveys a sorting object to be sorted, and a conveyor belt 11 is loaded with a sorting object such as waste. A hopper that can guide the sorted object to the carry-in side of the belt conveyor 10, a magnetic separator 12 that attracts and sorts magnetic materials such as iron scraps, and a belt conveyor 13 that is erected on the third base frame 4. 10 is a first conveyor column that supports 10, 14 is a second conveyor column that is erected on the front end of the frame 5 for supporting the sorting device and supports the belt conveyor 10, and 15 is a sorting device support. The rear end portion of the frame 5 of a conveyor supporting structure which supports the installed belt conveyor 10 so as to protrude rearward.

  The power unit 8 is disposed on the front end side of the first base frame 2 of the traveling body 1. The power unit 8 has a very large mass because it is equipped with main equipment necessary for driving a self-propelled sorting device such as a hydraulic pump, an engine, a hydraulic oil tank, and a fuel tank. By the way, the belt conveyor 10, the hopper 11, and the magnetic separator 12 are supported by a conveyor support structure 15 provided so as to protrude rearward from the rear end of the traveling body 1, and their weight is extremely high. Since it is large, a tipping moment that tries to tilt the traveling body 1 backward acts. In the example shown here, in response to such a problem, the power unit 8 having an extremely large mass is installed on the front end side of the first base frame 2 opposite to the support structure 15 for the conveyor. The power unit 8 functions as a counterweight, so that the self-propelled sorting device can be prevented from falling during sorting work or running.

  The belt conveyor 10 includes a conveyor frame that forms the framework of the belt conveyor, a drive pulley that is rotated by a motor to move the belt while turning, a driven pulley that guides the belt to be moved by the drive pulley, And a belt that circulates endlessly around the drive pulley and the driven pulley and circulates by driving the drive pulley. The belt conveyor 10 is arranged substantially horizontally on the traveling body 1 with such a height that it does not contact the top of the power unit 8 by the first conveyor column 13, the second conveyor column 14 and the conveyor support structure 15. It is supported. The driving pulley of the belt conveyor 10 is driven by a hydraulic motor using hydraulic pressure as a power source. In that case, by adjusting the flow rate of the pressure oil supplied to the hydraulic motor with a flow control valve (flow control valve) or the like, the rotation of the hydraulic motor can be changed, and thus the type of sorting work can be changed. Accordingly, the driving speed of the belt conveyor 10 can be adjusted appropriately.

  The belt conveyor 10 may be driven using an existing generator or commercial power source in the vicinity of the self-propelled sorting device as a power source. Further, power can be supplied from machines, devices, equipment, etc. in the vicinity of the self-propelled sorting device, such as other construction devices used in combination with the self-propelled sorting device. In any of these cases, a conveyor speed variable device (an inverter or the like) for changing the speed of the belt conveyor 10 is provided. When carrying out the invention of this application, the belt conveyor 10 may be another conveyor as long as it is a type of conveyor that conveys the objects to be sorted. The type of conveyor is not limited as long as it is a type of conveyor that can identify various materials from the objects to be sorted.

  It is desirable that the height of the objects to be placed on such a type of conveyor be as uniform as possible in the width direction of the conveyor so that workers can perform the sorting operation smoothly. Will be described in detail later. The hopper 11 is disposed immediately above the belt of the belt conveyor 10 and is supported by the conveyor frame. If a considerable amount of powder is mixed in the material to be sorted, the powder may be scattered by the wind during transport of the material to be sorted and the work environment may be deteriorated. Therefore, a watering nozzle for spraying water on the carry-in side of the belt conveyor 10 or in the hopper 11 may be provided.

  The magnetic separator 12 includes a driving pulley, a driven pulley, and a belt that circulates endlessly around both pulleys like a belt conveyor, and adsorbs a magnetic material such as iron scraps with the belt. It is configured so that it can be separated at various points and introduced into a discharging means for a selected item such as a chute described later. Such magnetic separators 12 are spaced apart on the conveyor 10 such that the belt moves across the belt conveyor 10 as shown in FIGS. In that case, the magnetic material is sorted by the magnetic separator 12 before the worker sorts the objects to be sorted carried from the hopper 11 to the belt conveyor 10, so that the burden of the worker's sorting work is slightly increased. In order to reduce, the magnetic separator 12 is arranged in front of the hopper 11 (downstream side) and behind the floor for worker placement. The magnetic separator 12 is detachably supported on the support structure 15 for conveyor, and the support means for that purpose will be described in detail later.

  Next, characteristic features of the self-propelled sorting device, such as the structure related to each invention of this application, will be described.

  1 to 10, reference numeral 16 denotes a floor installation frame on which a floor 17 is installed with a space on the sorting apparatus supporting frame 5, and 17 is a work provided on the side of the belt conveyor 10 for performing a sorting operation. A floor on which a member is arranged, 18 is a hydraulically driven floor lateral movement cylinder as a floor lateral movement means for moving the floor 17 in the left-right direction, and 19 is a floor installation frame 16 that is moved up and down. Accordingly, a hydraulically driven floor height adjusting cylinder as a floor vertical direction moving means for adjusting the height of the floor 17 by moving the floor 17 in the vertical direction, and 20 is a cylinder for adjusting the floor height. 19 is a floor support leg which supports the floor 17 moved by 19 so as to fix the position in the vertical direction.

  The floor 17 is placed on the floor installation frame 16 so as to be laterally movable on both the left and right sides of the belt conveyor 10, and as shown in FIG. Each have three worker spaces 16a (placements for workers) for placing workers for sorting work. As shown in FIGS. 5 and 10, the left and right floors 17 are respectively attached to left and right floor lateral movement cylinders 18 fixed on the floor installation frame 16. That is, the rod sides of the left and right floor lateral movement cylinders 18 are respectively attached to the left and right floors 17, and the bottom sides of the left and right floor lateral movement cylinders 18 are arranged at the center on the floor installation frame 16. It is fixed to the part.

  Accordingly, when the left and right floors 17 extend the left and right floor lateral movement cylinders 18, the left and right floors 17 respectively move laterally outward on the floor installation frame 16 and travel as shown in FIGS. 2 to 5. The effective space on the body 1 can be expanded laterally. In addition, when the left and right floor lateral movement cylinders 18 are contracted, the left and right floors 17 move inward in the lateral direction on the floor installation frames 16, respectively, as shown in FIGS. The lateral width of the traveling sorting device can be reduced. In the example shown in the figure, the floors 17 for arranging workers are provided on both the left and right sides, but may be provided only on one of the left and right sides.

  The cylinder 19 for adjusting the floor height is disposed at the center of the floor installation frame 16 in the front-rear direction and the left-right direction, and as shown in FIGS. 4 and 9, the lower bottom side is a frame for supporting the sorting device. 5 and the base frames 2 and 3 are fixed and the upper rod side is fixed to the floor installation frame 16. Therefore, when the cylinder 19 for adjusting the floor height is extended, the floor installation frame 16 can be raised as shown in FIGS. 1, 4 and 5, and the height of the floor 17 can be maximized. Further, when the cylinder 19 for adjusting the floor height is contracted, the floor installation frame 16 can be lowered as shown in FIGS. 6, 9 and 10 to make the floor 17 the lowest. The height of the floor 17 can be adjusted in multiple stages (three stages in the example shown in the figure) by adjusting the amount of expansion / contraction of the cylinder 19 for adjusting the floor height.

  As shown in FIGS. 1, 3, 4, 6, 8, and 9, the floor support legs 20 are provided on the left and right sides, respectively, at the front end, the center, and the rear end of the floor installation frame 16. It has been. Each floor support leg 20 has an upper end fixed to the floor installation frame 16 and a lower end inserted through a hole formed in the sorting device support frame 5. When it is raised and lowered by the cylinder 19 for adjusting the floor height, it is raised and lowered along with the frame 16. Each floor support leg 20 has a large number of pin holes (three pin holes in the example shown in the figure), and the frame 5 for supporting the sorting device also has pin holes at corresponding positions. Has been established.

  Therefore, the vertical position of the floor installation frame 16 can be fixed by inserting a pin into either the pin hole of the sorting device support frame 5 or the pin hole of the floor support leg 20. And the position of the up-down direction of the floor installation frame 16 to be fixed can be fixed in multiple stages by selecting the pin hole of the floor support leg 20 through which the pin is inserted. Therefore, the height of the floor 17 can be adjusted by the number of steps corresponding to the number of pin holes on the floor support leg 20 side by adjusting the expansion / contraction amount of the cylinder 19 for adjusting the floor height.

  By the way, the floor installation frame 16 descends due to leakage of pressure oil from the floor height adjusting cylinder 19 which inevitably occurs after the height of the floor 17 is adjusted. Lower. The floor support legs 20 serve to support the floor 17 that has been adjusted in height so as not to descend by fixing the vertical position of the floor installation frame 16 with pins as described above. Always keep the height position accurately. Further, since the floor 17 is supported by the floor support legs 20 after the height adjustment with the floor height adjustment cylinder 19, the number of expensive floor height adjustment cylinders 19 installed is minimized. It is economical because it can be held down (one in the example shown here).

  Thus, in the present self-propelled sorting apparatus, the floor height adjustment cylinder 19 is provided, and the floor 17 is moved up and down by the floor height adjustment cylinder 19, and then the moved floor 17 is moved up and down. The floor 17 can be fixed by the floor support leg 20, and the floor 17 is moved up and down by the floor height adjusting cylinder 19 and fixed by the floor support leg 20 as necessary. Thus, the relative height of the floor 17 with respect to the belt conveyor 10 can be adjusted. That is, it is possible to adjust the height of the belt conveyor 10 during the sorting operation for the worker.

  Therefore, when performing the sorting operation, the sorting operation is adjusted by adjusting the relative height of the floor 17 with respect to the belt conveyor 10 while taking into consideration the type of sorting work that each worker shares and the height of each worker. However, it is possible to set the height of the floor 17 so that it is as easy as possible for all the workers, or to set the height of the floor 17 so that no workers who are extremely difficult to perform the sorting work are generated. Thus, according to the present self-propelled sorting device, it is possible to facilitate the sorting operation of the worker by appropriately setting the relative height of the floor 17 with respect to the belt conveyor 10.

  In the example shown here, the height of the left and right floors 17 is adjusted to the same height, but the floor installation frame 16 is divided into left and right parts, and the left and right floor installation parts are divided into two parts. It is also possible to provide a floor height adjusting cylinder 19 for each frame 16 so that the height of the floor 17 can be adjusted separately on the left and right. Further, after dividing the left and right floors 17 into the front and rear, the floor installation frame 16 is divided into the front and the rear and a plurality of floor height adjusting cylinders 19 are provided in accordance with such a method. Can be adjusted separately in the front-rear direction.

  On the other hand, in this self-propelled sorting device, a hydraulically driven floor lateral movement cylinder 18 that can laterally move the floor 17 is provided. By extending the cylinder 18 and moving the left and right floors 17 laterally outward respectively, the effective space on the traveling body 1 is expanded in the lateral direction as shown in FIGS. In addition, a worker space 16a can be secured. Further, during the non-sorting operation, the floor lateral movement cylinder 18 is contracted and the left and right floors 17 are respectively moved inward in the lateral direction, thereby reducing the lateral width of the self-propelled sorting device as shown in FIGS. It is possible to reduce the size so as not to obstruct the movement, and it is possible to smoothly carry out the operation of making the work site self-propelled or transporting with a transport vehicle such as a truck or a trailer.

  Reference numeral 21 denotes a chute that protrudes to the side of the traveling body 1 so as to incline downward during the sorting operation, and guides the sorted matter to the outside of the machine. A chute pivoting member that is movably installed and pivotally pivoted on the upper end so that the chute 21 can swing, 23 is a container that introduces and stores the sorted material introduced into the chute 21, and 24 is a worker even during sorting work. 25 is a handrail which is formed by a linear member such as a steel wire and is erected outside the passage 24 so as to form a horizontal gap through which the chute 21 can pass. is there.

  As shown in FIGS. 4 and 5, the chute 21 protrudes to the side of the traveling body 1 so as to incline downward while being passed through the gap of the handrail 25 during the sorting operation. The discharge part is positioned on the upper opening of the container 23. In the example shown in the figure, three such chutes 21 are provided on both the left and right sides of the belt conveyor 10 corresponding to the worker space 16a, and are arranged beside the worker space 16a. The chute pivot member 22 is configured to be fixed by an appropriate means at a lowered position (see FIGS. 4 and 5) and a raised position (see FIGS. 9 and 10).

  Since the chute 21 is pivotally attached to the chute pivoting member 22, the left and right floors 17 are moved laterally outward as shown in FIGS. 4 and 5 when performing the sorting operation. When the chute pivot member 22 is lowered while passing the chute 21 through the gap between the handrails 25, the chute 21 is inclined downward and set in a use state. Thereafter, the chute pivot member 22 is fixed at this lowered position. Further, at the time of non-sorting work, when the chute pivoting member 22 set in such a state is raised, the lower end side of the chute 21 passes through the gap of the handrail 25 and enters the inside of the handrail 25, and the chute 21 As shown in FIG. 9 and FIG. 10, it is retracted into the machine and stood up along the chute pivot member 22. Thereafter, the chute pivot member 22 is fixed at this raised position. 9 and 10 show a state in which the lateral width of the self-propelled sorting apparatus is reduced by moving the left and right floors 17 inward in the lateral direction after setting the chute 21 in the unused state in this way. It is shown.

  Since this self-propelled sorting device has such a structure, at the time of sorting work, the worker overhangs the chute 21 installed by the side so as to tilt downward to the side of the traveling body 1, Sorted items from the sorting operation can be introduced into the chute 21 and guided outside the machine. As a result, the worker can perform the sorting operation with little movement, and thus the sorting operation can be performed efficiently. On the other hand, at the time of non-sorting work, the upper end side of the chute 21 is raised, so that the chute 21 can be retracted and stood in the machine, and as a result, the chute 21 can be stored in the machine. Therefore, the chute 21 can be cleaned up by a simple operation so that the effective space on the traveling body 1 is not narrowed when it is not necessary to use it, and the space on the narrow traveling body 1 can be effectively utilized. In addition, the chute 21 can be prevented from getting in the way when traveling on the work site or transporting with a transport vehicle.

  The handrail 25 is provided and configured such that the upper handrail 25b is slid in the vertical direction on the lower handrail 25a and can be fixed in the vertical position by appropriate means. By adopting such a structure, the self-propelled sorting apparatus moves the upper handrail 25b upward and fixes the position as shown in FIGS. 1 and 3 to 5 at the time of sorting work. The handrail 25 can be raised so that the safety of those who pass through the passage 24 can be ensured. Further, at the time of non-sorting work, as shown in FIGS. 6 and 8 to 10, the upper handrail 25 b is moved downward to fix the position, thereby reducing the height of the self-propelled sorting device. Therefore, it is possible to smoothly carry out work such as making the work site self-propelled or transporting with a transport vehicle such as a truck or a trailer. By the way, the height from the ground to the top of the handrail 25 needs to be 2700 mm or less in order to transport the self-propelled sorting device.

  Reference numeral 26 denotes a lower ladder as an ascending / descending step that is detachably erected on the traveling side frame 1 a of the traveling body 1 at a position in the front-rear direction near the front end of the passage 24 so that an operator can climb up to the height of the passage 24. 27 is an upper ladder that is attached to the floor installation frame 16 and extends to a position slightly higher than the belt conveyor 10, 28 is a roof support member that is connected to the upper ladder 27 and supports a simple roof 29 described later, This is a simple roof as a protective cover for the worker who acts as an awning or rain shield for workers on the floor 17.

  The lower ladder 26 is removed from the traveling side frame 1a and stored separately during non-sorting operations such as when the self-propelled sorting device is transported. The upper ladder 27 is composed of a pair of left and right long vertical members that are parallel to each other and a plurality of horizontal members that serve as footrests that connect the pair of long vertical members. It is installed. The column member 28 for roof is composed of a pair of left and right rod-like members arranged in parallel with each other at the same interval as the pair of long vertical members of the upper ladder 27. Each of the pair of long vertical members of the upper ladder 27 is formed in a hollow shape, and a pair of rod-shaped members constituting the support member 28 for the roof can slide in the vertical direction in the pair of hollow portions. Has been inserted.

  As shown in FIG. 1 and FIG. 3, the support member 28 for roof raises a pair of rod-shaped members, and the lower ends thereof are used as appropriate means for the upper ends of the pair of long vertical members of the upper ladder 27. As shown in FIGS. 6 and 8, the pair of rod-shaped members can be lowered and stored in the hollow portion of the long vertical member. The simple roof 29 uses, for example, a member such as a tent used during an athletic meet. As shown in FIGS. 1 and 3, the simple roof 29 is constructed by raising the four roof support members 28 and fixing them to the upper ladders 27 of the four corners of the floor installation frame 16. It is attached to the upper end part of 28 so that attachment or detachment is possible.

  Since the self-propelled sorting apparatus is provided with a simple roof 29 as a protective cover for workers and can be detachably installed as described above, the equipped simple roof 29 can be used in clear weather or rainy weather. Installation at times can prevent workers from being exposed to direct sunlight or rain. As described above, according to the self-propelled sorting device, the worker can be easily sorted by protecting the worker from sunlight and rain and improving the working environment. Further, when the simple roof 29 is not used, such as during non-sorting work, it can be stored as shown in FIGS. 6 and 8 so as not to get in the way.

  The above-described support means for detachably supporting the magnetic separator 12 on the conveyor support structure 15 will be described.

  As shown in FIGS. 1 and 3, the magnetic separator 12 is supported on the conveyor support structure 15 so as to be suspended from the magnetic separator rack 30. The magnetic separator frame 30 is as if it is placed by four legs 30a arranged at the four corners of a square and four connecting members 30b that connect the upper ends of the four legs 30a to each other. It is comprised like a support apparatus, and the rectangular plate-shaped attachment member 30c is each provided in each lower end of the four legs 30a. By fixing the mounting member 30c onto the conveyor support structure 15 by bolting, the magnetic separator base 30 is detachably mounted on the conveyor support structure 15 so as to be bridged on the belt conveyor 10. .

  The magnetic separator 12 is provided with a pair of front and rear rod-like members 12a each having a male spiral on the upper end side on the left and right sides of the upper part. On the other hand, the left and right connecting members 30b of the magnetic separator base 30 are respectively provided with rod insertion holes through which the rod-shaped member 12a can be inserted at positions corresponding to the rod-shaped member 12a. When the magnetic separator 12 is arranged on the belt conveyor 10, the rod-shaped member 12a of the magnetic separator 12 is inserted into the rod insertion hole formed in the connecting member 30b of the magnetic separator rack 30, and the male spiral of the rod-shaped member 12a. The magnetic separator 12 is attached and arranged by screwing and tightening a nut so as to sandwich the connecting member 30b from above and below. Since the magnetic separator 12 is not necessarily essential for the self-propelled sorting device, it is attached as an attachment according to customer options. When the magnetic separator 12 is not used or not required, the magnetic separator rack 30 is removed from the conveyor support structure 15 together with the magnetic separator 12 as shown in FIGS.

  Finally, in order to facilitate the sorting operation, the above-described means for making the height of the objects to be sorted placed on the conveyor uniform in the width direction of the conveyor is based on FIG. 11 and FIG. explain.

  FIG. 11 is an enlarged vertical sectional view of an essential part showing the internal structure of the hopper of the first example useful when installed in the self-propelled sorting apparatus of FIG. 1, and FIG. 12 is a self-propelled type of FIG. It is an expansion vertical sectional view of the principal part which expands and shows the internal structure of the hopper of the 2nd example useful when installed in a sorting device.

  The hopper 11 in any of the examples of FIGS. 11 and 12 exhibits a remarkable effect on the sorting operation by being installed in the self-propelled sorting device, and is to be sorted into the belt conveyor 10. Are arranged so as to be distributed in the width direction of the belt conveyor 10. In the hopper 11 of FIG. 11, a plurality of rod-shaped members 31 are arranged in the interior at intervals in a direction substantially parallel to the conveying direction of the belt conveyor 10. In that case, the plurality of rod-shaped members 31 are arranged so that the rod-shaped members 31 arranged at the center in the hopper 11 are arranged high and the rod-shaped members 31 arranged on both sides thereof are arranged slightly low. The hopper 11 is arranged so as to form a mountain shape having a vertex at the center.

  In the hopper 11 of FIG. 12, a plate-shaped member 32 having an arc-shaped cross section substantially parallel to the conveying direction of the belt conveyor 10 and a rod-shaped member 33 having an inclined surface inclined downward toward the outside are spaced apart. Placed in the hopper. In that case, the plate-like member 32 having an arc-shaped cross section is arranged at the center, and the rod-like members 33 are arranged on both sides of the plate-like member 32. Each of the sorting members in FIG. 11 and FIG. 12 subdivides the objects to be sorted into the hopper 11 and guides them to the both sides so that the objects to be conveyed into the belt conveyor 10 are conveyed to the belt conveyor 10. It works to distribute in the width direction.

  In the present self-propelled sorting apparatus, since such a sorting member is attached to the hopper 11, the sorting object carried into the belt conveyor 10 can be dispersed in the width direction of the belt conveyor 10. As a result, the objects to be sorted placed on the belt conveyor 10 are scattered so that the height thereof is more uniform than in the past in the width direction of the belt conveyor 10 without being fixed and transported to a specific portion on the belt conveyor 10. As a result, a sorting operation for distinguishing a predetermined sorting object from the sorting objects on the belt conveyor 10 can be performed more easily than in the past. As described above, according to the self-propelled sorting apparatus, when the sorting object is transported by the belt conveyor 10 during the sorting operation, the sorting object is transported while being distributed in the width direction of the belt conveyor 10. Therefore, it is possible to facilitate the worker's sorting operation.
