2. Assembly Procedure In the present embodiment, when the discharge conveyor 13 is assembled to the traveling body 1, the discharge conveyor 13 is first assembled in advance before the assembly. At this time, the conveyor frames 22a and 22b of the upstream conveyor 13a and the downstream conveyor 13b are connected to each other by pins 41 inserted into the brackets 22aa and 22ba from the outside in the horizontal direction. It is not necessary to prevent the split pins and the like from coming off, and the pins 41 and the bracket 42 are temporarily assembled.

  Before and after this, on the traveling body 1 side, the block 43 is aligned with the inner surface of the mounting portion 44 of the track frame 5 in the left-right direction of the airframe, and the bolt 46 is inserted from the outer side of the left-right direction of the airframe. 46 is screwed to the back nut 43 c of the block 43 to attach the block 43 to the track frame 5. At this time, the jaw crusher 12, the grizzly feeder 11, the hopper 10, the power unit 14, or the like is not necessarily assembled to the traveling body 1. However, when the discharge conveyor 13 is assembled, the traveling body 1 is self-propelled. Since the workability may be improved if the positional relationship with 13 can be adjusted, it is preferable to mount the power unit 14 in that case.

  Subsequently, the discharge conveyor 13 is placed between the left and right traveling devices 3 of the traveling body 1 (or the traveling body 1 is moved onto the discharge conveyor 13), and the discharge conveyor 13 is lifted by a lifting means such as a crane or a chain block. Then, the discharge conveyor 13 is held in a suspended posture, the support member 35 is connected to the upstream conveyor 13 a and suspended from the main body frame 4, and the downstream conveyor 13 b is connected to the front end portion 4 a of the main body frame 4. Then, before and after this, the brackets 42 temporarily attached to the upstream conveyor 13a and the downstream conveyor 13b by the pins 41 are overlapped on the inside of the block 43 attached to the track frame 5, and the left and right direction of the machine body The bolts 45 are inserted from the outside and the bolts 45 are screwed into the bolt holes 49 a to 49 d of the bracket 42, thereby connecting the bracket 42 to the inner wall surface of the track frame 5 in the left-right direction. When this connection is completed, the pin 41 is fixed to the track frame 5 while holding the conveyor frame 22 from the outside, and is restrained by the track frame 5, so that the pin 41 moves to the left and right with respect to the conveyor frame 22. This prevents the conveyor frame 22 from falling off the pins 41.

  Thereafter, if the jaw crusher 12, the grizzly feeder 11, the hopper 10, the power unit 14, or the like is not yet assembled, the assembly of the self-propelled crusher 100 is completed by assembling them sequentially to the traveling body 1.

  In the present embodiment, the upstream conveyor 13a and the downstream conveyor 13b of the discharge conveyor 13 are connected by pins 41, and the upstream conveyor 13a is bent with respect to the downstream conveyor 13b. By connecting the upstream end of the upstream conveyor 13a to the main body frame 4 via a cylinder (not shown) instead of 35, the upstream conveyor 13a can be swung up and down with the pin 41 as a fulcrum. it can. When configured in this way, it is desirable not to hold the upstream conveyor 13a only by the cylinder but to arrange support members that can selectively hold the upstream conveyor 13a according to the angle.

3. Operation Next, the operation of the self-propelled crusher 100 configured as described above will be described.

  For the self-propelled crusher 100 during the crushing operation, an object to be crushed is put into the hopper 10 by a loading heavy machine such as a wheel loader. At this time, in the configuration of FIGS. 1 to 7, the object to be crushed is thrown into the hopper main body 27 from the right side of the machine body without the turning member 28. The charged material to be crushed is guided onto the grizzly feeder 11 and conveyed toward the jaw crusher 12. At that time, fine particles (slipping etc.) smaller than the gaps between the comb teeth 18 of the grizzly plate 19 are guided to the discharge conveyor 13 through the gaps through the chute 21 and larger objects (large blocks) ) Is supplied to the jaw crusher 12. The object to be crushed supplied to the jaw crusher 12 is crushed to a particle size corresponding to the exit gap of the crushing chamber between the fixed teeth and the moving teeth and falls onto the discharge conveyor 13 below. The crushed material crushed by the jaw crusher 12 joins the fine particles selected by the grizzly feeder 11 and is conveyed forward by the discharge conveyor 13, and foreign substances such as reinforcing bars are adsorbed and removed by the magnetic separator 24 on the way. It is carried out of the machine above.

4). Effects According to the present embodiment, the following effects can be obtained.

(1) Improving workability of assembly and disassembly of discharge conveyor 13 First, an intermediate portion of the conveyor frame 22, in this embodiment, a connecting portion of the upstream and downstream conveyors 13 a and 13 b is connected to the traveling body 1 with a pin 41. When connecting, the bracket 42 fixed to the pin 41 is fixed to the mounting portion 44 of the track frame 5 via the block 43, so that the discharge conveyor 13 is simply inserted into the conveyor frame 22 before the assembly to the traveling body 1. The pin 41 in a state where it is simply held is restrained from being removed from the conveyor frame 22 by the assembly of the discharge conveyor 13. Moreover, as the bolts 45 and 46 are used for this coupling operation are both being adapted to be screwed into the horizontal direction from the outside of the machine body lateral direction inside the horizontal direction of the machine body, and yet shown in FIG. 9, etc. Since the mounting portions 44 of the bolts 45 and 46 protrude forward from the post portion 48 of the track frame 5 and can be accessed from the side of the airframe, the bolts can be passed through the traveling device 3 without being submerged in the lower portion of the traveling body 1. 45 and 46 can be screwed.

  As described above, the pin 41 that connects the upstream conveyor 13a and the downstream conveyor 13b is used as a part of the connecting means of the discharge conveyor 13 and the traveling body 1, and the fixing operation of the pin 41 is performed by the assembly work of the discharge conveyor 13. In addition to being shared, the work at that time can be easily performed from the side of the machine body, so that the workability of disassembly and assembly of the discharge conveyor 13 can be improved. The downtime associated with disassembly / assembly work can be reduced.

(2) Possibility of widening the discharge conveyor 13 Generally, the intermediate portion of the conveyor frame is suspended from the main body frame of the traveling body via a support member, and the support member is connected to the upper surface of the conveyor frame. The Since this support member is installed on the inner side in the left-right direction of the machine from the track frame, there is a gap between the discharge conveyor and the track frame, and there is a space between the left and right track frames to increase the width of the discharge conveyor. It was difficult to take enough.

  On the other hand, in this embodiment, since the conveyor frame 22 is connected to the track frame 5 via the pin 41, the bracket 42 and the block 43, the gap between the discharge conveyor 13 and the track frame 5 is reduced. The space between the left and right track frames 5 can be effectively utilized to take the width of the discharge conveyor. Thus, in the meaning which contributes to the widening of the discharge conveyor 13, in this embodiment, the block 43 is interposed between the bracket 42 to which the pin 41 is fixed and the mounting portion 44 of the track frame 5, but the block 43 is omitted. A configuration in which the bracket 42 is directly connected to the mounting portion 44 is also conceivable.

(3) Strength improvement In the case where the intermediate portion of the discharge conveyor 13 is suspended and supported by a support member, it is easily swayed in the horizontal direction due to vibration during operation or the like, but in this embodiment, it is rigid by being connected to the track frame 5. And the swinging of the discharge conveyor 13 can be suppressed.

5. Others In the above-described embodiment, the discharge conveyor 13 is illustrated in which the upstream conveyor 13a can be bent with the pin 41 as a fulcrum with respect to the downstream conveyor 13b. However, the discharge conveyor 13 does not necessarily have a bent structure. Is also applicable to a fixed frame type discharge conveyor that does not bend. This is because even if the frame is fixed, the pin 41 can be inserted from the side and connected to the track frame 5 via the bracket 42 or the like.

In addition, the mounting portion 44 protrudes forward from the post portion 48 of the track frame 5 so that the bolts 45 and 46 can be easily operated from the side of the machine body, but the conveyor frame 22 is connected to the track frame 5 via the pins 41. For connection, the attachment portion 44 does not necessarily protrude forward. For example, the bracket 42 and the like can be directly connected to the wall surface of the post portion 48 of the track frame 5 on the inner side in the left-right direction of the body.

  Moreover, although the case where this invention was applied to the self-propelled crusher 100 which provided the discharge conveyor 13 on the opposite side to the hopper 10 (accepting object to be crushed) has been described as an example, it is discharged to the same side as the hopper. The present invention can also be applied to a self-propelled crusher having a configuration provided with a conveyor. Moreover, although the case where this invention was applied to the crawler type self-propelled crusher 100 having the crawler belt 8 of the endless track as the traveling means has been described as an example, the wheel-type self-propelled processing having the tire as the traveling means is described. The present invention is also applicable to a machine. In these cases, similar effects can be obtained.

  In addition, the present invention is not limited to a self-propelled crusher, but is a self-propelled type in which a processing device related to production of a recycled product or a production support such as a so-called self-propelled soil improvement machine or a self-propelled screen is mounted on a traveling body Applicable to all processing machines. Specifically, the self-propelled crusher 100 is provided with a crushing device (jaw crusher) 12 as a processing device for supplying and crushing an object to be processed such as rock between a swinging moving tooth and a fixed tooth. Although the case where the invention is applied has been described as an example, for example, a rotary crushing apparatus (roll crusher or the like) that crushes a workpiece such as rocks between a pair of roll-shaped rotating bodies having a crushing blade. ), Shearing crushing device (shredder) that shears and crushes tires and home appliances, etc., crushing device that crushes workpieces such as rocks by impact with impact plates and impact plates with impact tools (impact) Crusher), rotors with cutters, rotors with bits, and crushing devices (wood crushing devices) that crush workpieces such as wood, branch timber and construction waste wood with repulsion plates, etc. Self-propelled crusher Also the invention is applicable. In addition, for example, a self-propelled soil improvement machine that produces treated material (improved soil) by mixing construction generated soil generated at the construction site with treated soil material as treated material, and depending on the particle size of the treated material The present invention can also be applied to a self-propelled screen provided with a screen (sieving device) for sorting. In these cases, similar effects can be obtained.
