[Problems to be solved by the invention]
  By the way, in order to carry the self-propelled crusher into a site with a limited work space and operate it without excess or deficiency, the machine body is required to be as compact as possible and to have stable running performance. However, if the engine is placed behind the machine body as in the conventional example, the hopper, crusher and engine are lined up in a series and the machine body's longitudinal dimensions are longer, and the center of gravity is behind the carriage, making it stable. A slow movement is forced to perform the running.
[0006]
  In addition, if the engine is to be arranged behind the machine body, interference with the conveyor must be avoided. As a result, the position of the center of gravity of the engine becomes high and stability is lost. Furthermore, in such a case, the rear surface of the crusher is blocked with an engine, and it becomes difficult to maintain the crusher.
[0007]
  The upper part of the feeder between the hopper and the crusher is a work space for manually removing foreign matters that are not desirable for the crusher, such as wood, paper, reinforcing bars and scraps, before crushing, and increasing crushing efficiency. ing. However, as described above, a sufficient space cannot be secured for this work space because the longitudinal dimension of the machine body cannot be increased. If sufficient work space cannot be secured, not only the workability for removing foreign matter will deteriorate, but also there will be a problem that it is not possible to secure a place where workers can safely wait when throwing construction waste into the hopper with an excavator. is there.
[0008]
  The present invention has been made in view of the above circumstances, and a first object is to provide a self-propelled crusher that can exhibit compact and stable traveling performance, and a second object is sufficient work. The purpose of the present invention is to provide a self-propelled crusher that can secure space and increase crushing efficiency, and a third object is to provide a self-propelled crusher that is excellent in assembly and maintenance.
[0009]
[Means for Solving the Problems]
  The present inventionPertaining toThe self-propelled crusher includes a crushing device, a power source that drives the crushing device,A hopper into which a material to be crushed by the crushing device is input, and a material to be crushed from the hopperComprising a feeder for transporting toward the crushing device, and a self-propelled carriage on which these are mounted,The power source and the feeder are arranged side by side on either one of the front and rear sides of the self-propelled carriage, the crushing device is arranged on the other side, and the hopper has a large opening and a downward direction. The opening area is narrowed, and the material to be crushed from above is disposed above the feeder so that the crushed object is guided to the feeder by the inclined surface of the inner wall, and the power source is located on the side of the feeder. And at least a part is arranged vertically along the front-rear direction of the self-propelled carriage at a position below the inclined surface of the inner wall of the hopper.This is the gist.
[0010]
  The present inventionAccording toSince the power source and the feeder are arranged side by side on the left and right, the longitudinal length of the traveling carriage can be shortened. As a result, the transportability is greatly improved and the carrying-in to the site becomes easy. If the space created by shortening the overall length is allocated to the expansion of the work space, foreign objects that are not desirable for the crusher can be surely removed before crushing, and clogging of foreign objects can be eliminated to increase crushing efficiency. Can do.
[0011]
  In the self-propelled crusher, the crushing device is arranged in a state where the center of gravity is located on one side with respect to the front-rear direction center of the self-propelled carriage, and the power source has a center of gravity before and after the self-propelled carriage. It is preferable that they are arranged on the other side with respect to the direction center.

  the aboveSelf-propelled crusherIn,It is preferable that a hopper is disposed in the vicinity of one of the front and rear sides of the self-propelled carriage..
[0013]
  thisConstitutionIf it follows, since the distance of a hopper and a crushing apparatus can be enlarged, the conveyance path of a feeder can be taken long. Thereby, it is possible to reliably remove small-sized objects to be crushed that do not need to be put into the crushing apparatus. Further, since the work space for carrying out the foreign substance removal work is expanded by expanding the feeder conveyance path, the foreign substance can be reliably removed.
[0014]
  the aboveSelf-propelled crusherIn,The apparatus further includes a discharge conveyor for discharging the crushed material crushed by the crushing apparatus to the outside, and the discharge conveyor is inclined downward and forward from the lower part to the front or rear from the lower part. It is preferable to have an inclined portion that.
[0015]
  thisConstitutionIf it follows, since it is not necessary to extend a discharge conveyor through a motive power source conventionally, the length of a discharge conveyor can be shortened. Thereby, the crusher can be made compact.
[0016]
  the aboveSelf-propelled crusherIn,It is preferable that the apparatus further includes a foreign matter sorting device that is provided above the feeder and sorts foreign matter contained in the object to be crushed conveyed by the feeder..
[0017]
  Conventionally, since the foreign matter sorting device is arranged on the downstream side of the crushing device and above the carry-out conveyor, clogging of the crushing device due to reinforcing bars, for example, could not be resolved, but according to the seventh aspect, the upstream side of the crushing device Therefore, it is possible to avoid clogging of the crushing device and damage to the belt of the discharge conveyor.
[0018]
  The said foreign material selection apparatus can be comprised from the magnetic separator which adsorb | sucks the foreign material contained in a to-be-crushed object using magnetic force.
[0019]

On the other hand, it is preferably arranged eccentrically on the other side in the left-right direction..
[0020]
  the aboveSelf-propelled crusherInthe aboveThe feeder has a conveyance path of the object to be conveyed by the feeder from the front side to the rear side of the center of the self-propelled carriage.Range up toIt can be extended so as to cross over.
[0021]
  In the above self-propelled crusher, On the left and right sides of the above self-propelled carriageProvidedTraveling crawlerFurtherPreparation,UpThe power source can be arranged with a position shifted in the front-rear direction with respect to the traveling crawler so that a working space for attaching and detaching components to the power source can be secured.
[0022]
  Thereby, since there is no traveling crawler below the power source, it is possible to work from below the power source when accessing the power source for maintenance or the like. Note that shifting the position in the front-rear direction means that the end of the traveling crawler and the power source are partly viewed from the plane as long as the traveling crawler does not interfere with work when accessed from below the power source. Overlapping arrangements are also included.
[0023]

DETAILED DESCRIPTION OF THE INVENTION
  FIG. 1 is a plan view of a first self-propelled crusher according to the present invention, FIG. 2 is a side view seen from the left side in the traveling direction of the self-propelled crusher, and FIG. 3 is a side view seen from the right side. 4 is a front view of the self-propelled crusher, and FIG. 5 is a rear view thereof (however, the crusher and the rising part of the conveyor are omitted).
[0030]
  In each figure, the traveling direction of the self-propelled crusher is front (F), the direction opposite to the traveling direction is rear (A), the left in the traveling direction is left (L), the right in the traveling direction Is the right (R) and the upper is the upper (U).
[0031]
  1 and 2, a self-propelled crusher is a type of recycling machine for crushing and reusing construction waste (crushed materials) such as concrete trash and rocks that are generated when buildings and bridges are demolished. And it is comprised from the self-propelled cart 1 and the machine main body 2 mounted on the self-propelled cart 1.
[0032]
  The self-propelled carriage 1 includes a frame 3, left and right crawler frames 4, and crawlers 5, and both crawlers 5 are driven to rotate individually by left and right traveling hydraulic motors 6.
[0033]
  The machine body 2 includes a hopper 7 at the front end of the self-propelled carriage 1, and the construction waste thrown into the hopper 7 is conveyed to the rear side of the main body by the feeder 8. The crusher 10 is disposed in the section.
[0034]
  The crushed material crushed by the crusher 10 is discharged from the lower portion of the crusher 10 by a discharge conveyor 11 that is inclined upward (see FIG. 2).
[0035]
  In this configuration, the center of gravity of the crusher 10 that is the most heavy object is arranged on the rear side with respect to the center position in the front-rear direction of the self-propelled carriage 1, and the engine 9 that is another heavy object It is arrange | positioned ahead with respect to the center position of the front-back direction. Furthermore, a hopper 7 and an engine 9 are arranged side by side on the front side.
[0036]
  By the way, the center-of-gravity position G of the machine main body 2 is the center position of the self-propelled carriage 1 (the intersection of the left-right direction center line C1 and the front-rear direction center line C2 in FIG. 1). Are not necessarily the same, but it is preferable to substantially match the two in order to ensure the running stability of the self-propelled carriage 1 on which the machine body 2 is mounted. In FIG. 1, the case where both are made to correspond is shown.
[0037]
  Specifically, as shown in FIG. 1, the crusher 10, the feeder 8, and the hopper 7 are aligned with the center line C <b> 3 in the left-right direction, and the center line C <b> 3 is the center line C <b> 1 in the left-right direction of the self-propelled carriage 1. Is slightly eccentric to the left. On the other hand, the engine 9 is placed vertically along the front-rear direction, and is arranged close to the right end in the left-right direction so that it can be arranged on the right side of the hopper 7 within the width of the self-propelled carriage 1.
[0038]
  In this configuration, the length in the front-rear direction of the machine main body 2 can be shortened by the width of the engine 9 at the maximum as compared with the case where the engine 9 is arranged behind the machine main body 2 as in the past.
[0039]
  On the other hand, there is originally an empty space on both the left and right sides of the hopper 7 and above each crawler 5, and even if the engine 9 is arranged in this empty space, the width in the left-right direction of the machine body 2 does not increase. Therefore, since the machine body 2 can be made compact by such an arrangement, even when there is a restriction on the vehicle width and the vehicle length when the self-propelled crusher is brought into the site, it can be cleared. Can fully demonstrate self-propelled ability in a narrow field.
[0040]
  In addition, with such an arrangement, the front / rear and left / right balance of the machine body 2 is also maintained. That is, in the self-propelled crusher, the weight of the machine main body 2 provided with the crusher 10 is large. Therefore, if the balance between the front, rear, left and right is bad, the load applied to the both crawlers 5 of the self-propelled carriage 1 equipped with the machine main body 2 is increased. It becomes uneven. If the load of the traveling hydraulic motor 6 is different on the left and right, the straight traveling performance is deteriorated and the work on the slope is unstable.
[0041]
  However, in the present embodiment, as described above, the balance between the front, rear, left and right of the machine body 2 is maintained, so there is no such problem, and stable running performance of the self-propelled carriage 1 equipped with the machine body 2 is always ensured. Is done. Further, even during high-speed transport by a trailer, cargo collapse is less likely to occur and safety can be improved.
[0042]
  In addition, the arrangement opposite to the above, for example, the crusher 10 is arranged in the front, the hopper 7 and the engine 9 are arranged in the rear, or the direction in which the crusher 10 is decentered and the direction in which the engine 9 is offset are described above. It goes without saying that may be reversed.
[0043]
  Hereinafter, each component will be described in more detail.
[0044]
  In FIG. 4, the hopper 7 has a large rectangular opening at the top and the opening area is narrowed downward, and construction waste material carried by a hydraulic excavator or the like is introduced from the opening.
[0045]
  Corresponding to the relationship between the center lines C1 and C3 described above, the center line C3 'in the left-right direction of the support frame (not shown) of the hopper 7 is slightly leftward from the center line C1' in the left-right direction of the self-propelled carriage 1. Because of the eccentricity, a large free space can be secured on the right side of the machine body 2. Therefore, even if the engine 9 is placed vertically on the right side of the hopper 7, there is no possibility that the hopper 7 interferes with the engine 9, and the hopper 7 that is the maximum height of the machine body 2 is raised just because the engine 9 is arranged. There is no need to do.
[0046]
  Returning to FIG.
[0047]
  The feeder 8 is a grizzly feeder provided with four stages of grizzlies 81 having comb-like portions disposed below the hopper 7, and the hopper is vibrated by vibrating the feeder 8 with a feeder hydraulic motor (not shown). The construction waste falling from 7 is sequentially transported to the crusher 10, and the fine earth and sand adhering to the construction waste during the transportation and small pieces that do not need to be crushed are dropped by gravity from the gaps of the comb teeth, Construction waste larger than the size is selected.
[0048]
  In the present embodiment, as described above, the machine body 2 is made compact by placing the engine 9 vertically and arranging it on the side of the hopper 7, so that the space between the crusher 10 and the hopper 7 is reduced. It becomes possible to take larger than the conventional one. As the space is expanded, the grizzly 81 is extended from the front side to the rear side of the front-rear direction center C2 (see FIG. 1) of the self-propelled carriage 1, and the grizzly 81 is moved in the front-rear direction. Four stages (81a to 81d) can be provided.
[0049]
  FIG. 6 schematically shows a connecting portion between the feeder 8 and the crusher 10, wherein (a) is a side view and (b) is a plan view.
[0050]
  Each grizzly 81a-81d has a comb-like shape extending a predetermined length in the front-rear direction, and is arranged in a descending step shape from the front to the back. With this configuration, when the feeder 8 is vibrated, construction waste materials are sequentially conveyed by the vibration from the most upstream grizzly 81a to the most downstream grizzly 81d. Since small pieces that do not need to be crushed are removed by gravity dropping, a sufficient separation ability can be ensured, and as a result, the load on the crusher 10 is reduced.
[0051]
  Further, the feeder 8 is provided with a plate portion 81e further downstream of the most downstream side grizzly 81d. Since the plate portion 81e is not formed with a through hole for dropping small pieces that do not need to be crushed, foreign matters can be removed without being obstructed by the gaps between the comb-like portions of the grizzly.
[0052]
  In addition, when the distance between the crusher 10 and the hopper 7 is the same as the conventional one and the grizzly 81 is configured in two stages of the conventional configuration, the conventional engine arrangement space can be omitted, so It is possible to shorten the discharge conveyor 11 that has been extended by passing the. Thereby, the machine body 2 can be made compact.
[0053]
  In FIG. 5, on the left side of the feeder 8 (on the side opposite to the engine 9), a work deck 82 provided with a handrail as a fence and a ladder 83 for ascending and descending the work deck 82 are provided. The worker can go up from the ladder 83 to the work deck 82 and remove foreign matters such as reinforcing bars, iron scraps, wood, paper, and the like from the construction waste being conveyed on the grizzly 81.
[0054]
  The work deck 82 preferably has a wide space for ensuring the workability and safety of the worker. Therefore, as described above, if the space between the crusher 10 and the hopper 7 can be made larger than before, the length in the front-rear direction of the work deck 82 can be expanded accordingly. Thereby, as shown in FIG. 2, when putting construction waste into the hopper 7 with an excavator, the worker can retreat away from the working range of the bucket B.
[0055]
  In FIG. 3, the crusher 10 is constituted by a so-called jaw crusher that crushes a moving tooth (swing jaw) 101 with respect to a fixed tooth 102 and crushes between both teeth. The upper end of the moving tooth 101 is attached eccentrically to a rotating shaft (eccentric shaft) 103, and the lower end of the moving tooth 101 is supported by a toggle block 101a fixed to the frame via a toggle plate (not shown). Has been. Then, by adjusting the fixing position of the toggle block 101a with respect to the frame in the front-rear direction, the minimum gap between the moving tooth 101 and the fixed tooth 102 can be set, and thereby the particle size of the crushed pieces can be adjusted. It has become. A tension spring 101b is provided between the back surface of the moving tooth 101 and the frame.
[0056]
  The rotating shaft 103 is rotated by a crusher hydraulic motor 104. Then, the crusher hydraulic motor 104 is driven to rotate the rotating shaft 103 to cause the upper end portion of the moving tooth 101 to rotate eccentrically, and to move the lower end portion of the moving tooth 101 so as to draw a predetermined locus. Thus, the moving tooth 101 is caused to swing with respect to the fixed tooth 102.
[0057]
  The discharge conveyor 11 is a horizontal conveyance portion disposed below the crusher 10.(Lower part)And the inclined conveyance part inclined forward from this horizontal conveyance part(Inclined part)The inclined conveyance portion extends toward the upper rear part of the machine body. The crushed material crushed to a predetermined size by the crusher 10 is placed on the endless belt 111 that is circulated and driven by the driving force of the conveyor hydraulic motor 112. In the magnetic separator 12 provided in the rebar, rebars, iron scraps and the like contained in the crushed material being conveyed are magnetically adsorbed and removed.
[0058]
  In the present embodiment, the discharge conveyor 11 is arranged approximately at the center in the left-right direction of the machine body. However, the discharge conveyor 11 may be arranged eccentrically on either the left or right side so that the discharge conveyor 11 can be easily maintained.
[0059]
  As shown in FIG. 1, the magnetic separator 12 includes a permanent magnet 123 inside the endless belt 122 that is driven by the magnetic separator hydraulic motor 121, in a direction substantially orthogonal to the belt traveling direction of the discharge conveyor 11. The endless belt 122 is disposed. And the magnetic force of the permanent magnet 123 is made to act on the discharge conveyor 11 via the endless belt 122, and reinforcing bars and iron scraps of the crushed material moving on the discharge conveyor 11 are attracted to the endless belt 122.
[0060]
  FIG. 7 schematically shows the foreign substance removal operation by the magnetic separator 12.
[0061]
  First, in FIG. 2A, the reinforcing bars S and iron scraps on the discharge conveyor 11 are attracted by the magnetic force of the permanent magnet 123. Next, as shown in FIG. 2B, when the reinforcing bar S is adsorbed by the endless belt 122 traveling, the reinforcing bar S is taken out from the conveying path of the discharge conveyor 11. Next, as shown in FIG. 3C, when the reinforcing bar S is conveyed to a place where the magnetic force is weak, the reinforcing bar S is naturally detached from the endless belt 122 and discharged to the chute 124.
[0062]
  In the above embodiment, the magnetic separator 12 having the above-described configuration is disposed on the conveyance path of the discharge conveyor 11, but may be disposed above the feeder 8 instead of or in addition to this. When the magnetic separator 12 is disposed above the feeder 8, the rebar S and scrap can be removed before the object to be crushed is put into the crusher 10.
[0063]
  In addition, since the crusher 10 is arrange | positioned in the rearmost part in arrangement | positioning of this embodiment, the length of the horizontal part in the discharge conveyor 11 can be shortened compared with the conventional structure which arrange | positions a crusher in the body center. Thereby, the processed crushed material can be conveyed with the conveyor with a small conveyance capability compared with the past.
[0064]
  The engine 9 drives a hydraulic pump (not shown), and each hydraulic motor is driven by supplying pressure oil from the hydraulic pump to each hydraulic motor via a control valve (not shown). The engine 9 and hydraulic equipment such as a hydraulic pump and a control valve may be centrally arranged as an integral power unit.
[0065]
  In the arrangement described above, the engine 9 does not need to be arranged upward in order to avoid interference with the discharge conveyor 11 as in the case where the engine is arranged rearward as in the conventional example. It can be installed at the lowest possible position above, and the stability and maintainability of the machine body 2 are further improved.
[0066]
  Hereinafter, the operation of the self-propelled crusher will be described.
[0067]
  In FIG. 1, when construction waste carried by a hydraulic excavator or the like is introduced into a hopper 7 disposed on the front side of the machine body, the introduced construction waste is guided to the inclined surface of the inner wall of the hopper 7 and is placed on the grizzly 81 of the feeder 8. fall into. When each stage of the grizzly 81 is vibrated by the feeder hydraulic motor, the construction waste is sequentially moved toward the crusher 10 by the feeder. During the conveyance, the small pieces contained in the construction waste fall from the lattice gaps of the grizzly 81 at each stage and are received on the belt 111 of the discharge conveyor 11.
[0068]
  Further, when the construction waste is transported by the feeder 8, the worker goes up to the work deck 82, and foreign matters such as reinforcing bars, iron scraps, wood, paper, etc. mixed in the construction waste are manually removed.
[0069]
  Subsequently, the crushed material is put into the crusher 10 in operation.

  The engine 211 of the second self-propelled crusher 200 is arranged above the traveling crawler 205 as shown in the front view of FIG. 10, but as shown in FIG. The portion 205a is arranged in a column in the upper direction and the front side from the start end.
[0086]
  In the layout in which the engine 211 is mounted on the side of the feeder 208, the vehicle width cannot be expanded unnecessarily, so the engine 211 must be disposed on the traveling crawler 205. At this time, if the vehicle height is lowered with the configuration in which the engine 9 is disposed on the traveling crawler 5 as shown in FIG. 3, for example, when oil is changed, the oil pan 9 a and the traveling crawler 5 Due to the narrow interval, the oil receiving container cannot be inserted and applied to the lower side of the oil pan 9a, and is discharged from the oil discharge port (drain plug as a part that can be attached to and detached from the drain cock or power source). Can no longer receive the oil.
[0087]
  Therefore, a hose prepared separately is connected to the drain cock and must be discharged by sucking the oil, which makes the work complicated.
[0088]
  Further, if there is not enough space for the operator to enter below the engine 211, the clearance S on the traveling crawler 205 is usually used to open and close the drain cock 211a provided on the lower side of the engine 211 (see FIG. 4). Therefore, the operator must be stretched out of the hand and the drain cock 211a is difficult to see, which places a burden on the operator.
[0089]
  Further, not only oil replacement but also other engine maintenance work cannot be performed directly from below the engine. Specifically, in FIG. 8, when oil leaks from the seal surface of the oil pan 211b mounting portion, the oil pan mounting bolt is removed, the oil pan 211b is removed, and the gasket is replaced. If there is a traveling crawler 5 below the engine 211, the oil pan 211b cannot be removed. In this case, the engine 211 is once lowered from the machine main body 202 to work. Therefore, maintenance workability is extremely deteriorated. The oil pan 211b is also regarded as a component that is attached to and detached from the power source.
[0090]
  On the other hand, in this embodiment, since the traveling crawler 205 does not exist below the oil pan 211b, the worker O can enter below the oil pan 211b, and the oil pan 211b is removed downward. Can do. In the drawing, 211b ′ indicated by hatching indicates a state where the oil pan is removed from the engine 211, and a sufficient working space is secured below the engine 211. Specifically, a work space is secured for attaching and detaching components that can be removed only downward or obliquely downward with respect to the power source.
[0091]
  Note that the oil pan 211b does not necessarily have to be in the vertical direction as long as it can be removed downward, and may be removed by moving obliquely forward, backward, or laterally. That is, as shown in FIG. 8, the engine 211 may partially overlap above the rear end portion 205a of the traveling crawler 205. By doing so, the total length of the self-propelled crusher 200 can be shortened.
[0092]
  A hydraulic pump 213 is connected to the output shaft of the engine 211. The hydraulic pump 213 is driven using the engine 211 as a drive source and supplies pressure oil to the hydraulic circuit.
[0093]
  The arrangement of the hydraulic pump 213 and the traveling crawler 205 will be described below.
[0094]
  When the engine 211 is arranged with the rear end 205a of the traveling crawler 205 as the starting end and in front of it, the engine 211 is arranged with the cooling fan 211c behind, and the hydraulic pump 213 provided on the opposite side of the cooling fan 211c The traveling crawler 205 can be arranged so as not to overlap in the vertical direction.
[0095]
  If the traveling crawler 205 is disposed close to the lower side of the hydraulic pump 213, the hydraulic pump 213 cannot be accessed from the lower side during assembly work or maintenance, and workability is deteriorated. Specifically, it is necessary to connect a large number of pipes and wires to the hydraulic pump 213, and tightening work is involved for each pipe. In this case, if the tightening operation cannot be performed from below the hydraulic pump 213, a tightening portion where the spanner cannot be rotated is generated.
[0096]
  Therefore, as shown in FIG. 8, when the hydraulic pump 213 is arranged at a position where it does not interfere with the traveling crawler 205, the piping and wiring can be easily attached, and the workability is greatly improved. In addition, since the worker can perform the above-described maintenance work such as attaching and detaching parts downward while standing on the ground without climbing on the ladder or the airframe, the safety of the work can be improved.
[0097]
  In the above-described embodiment, the radiator side that is the cooler of the engine is disposed rearward, and the hydraulic pump is disposed on the front side, that is, on the front end side of the body. However, the present invention is not limited to this configuration, and the engine can be arranged in the opposite direction, and a radiator can be arranged on the front end side of the machine body and a hydraulic pump can be arranged behind the engine. In this reverse arrangement, the cooling efficiency of the engine can be increased and the piping connecting the hydraulic pump to the actuators such as the crusher motor and conveyor motor can be shortened. The cost can be reduced and the cost can be reduced.
