As described above, there is a problem that the weight of the conveyor device increases. When the weight increases, it is necessary to transport it using a large trailer that can withstand the weight, which has been a disadvantage for the installer and the owner of the self-propelled crusher in terms of maintenance costs. Similarly, for the manufacturer, the manufacturing unit price increased and was a disadvantage.

In order to solve this problem, an upstream-side conveyor device that receives an object to be crushed and a two-stage conveyor device that can be transferred (discharged) from the conveyor device are disclosed. The belt width of the upstream conveyor device (hereinafter referred to as the primary conveyor device) is configured to be approximately the same as that of the prior art, and a throttle is provided on the downstream side of the conveyor device, and the destination conveyor device ( The belt width of the secondary conveyor device) is reduced. Thereby, it conveys (discharges) stably outside, reducing the weight of the whole conveyor apparatus.

The bolt hole provided on the member 26 side has a long hole 26a which is long in the vertical direction. Thereby, the mounting height can be adjusted in the height direction. This is provided to adjust the gap between the driving wheel 10 and the driven wheel 18 when the inclination of the secondary conveyor device 7b is changed.

It has a function of smoothly guiding the wood chipper transferred to the secondary conveyor device 7b side to the belt 17 of the secondary conveyor device 7b. The reason for forming with rubber is to prevent the belt 17 from being damaged by friction with the belt 17.

  The self-propelled crusher according to the embodiment has the above-described configuration and operates as follows.

  Waste wood (material to be crushed) is put into the feeding hopper 4 by a wheel loader (not shown) or a hydraulic excavator (not shown). Waste wood is transported into the crushing chamber 3 by driving a transport conveyor (not shown) in the charging hopper 4.

  The transported waste wood is gradually scraped by the rotation of a crushing rotor (not shown) provided in the crushing chamber 3 to be crushed pieces. When the crushed pieces collide with an anvil (not shown) as a fixed blade provided in the crushed chamber 3, the crushed pieces are crushed and become a finer-sized wood chipper (crushed material).

  The crushed wood chipper falls onto a primary conveyor device 7a provided below the crushing chamber 3, and is conveyed toward the secondary conveyor device 7b by driving the belt 9 of the primary conveyor device 7a. On the downstream side of the primary conveyor device 7 a, the wood chipper is brought close to the center side of the belt 9 by the guide member 11.

  The wood chipper falls onto the belt 17 of the secondary conveyor device 7b from the end of the belt 9 on the drive wheel 10 side of the primary conveyor device 7a. At this time, the first chute member 20, the scattering prevention covers 8a, 8b, and 21 and the second chute member 27 are transferred to the secondary conveyor device 7b while preventing the wood chipper from scattering and spilling.

  The wood chipper that has not been scraped off by the scraper 14 is further suppressed by the rubber member 23, the L-shaped member 24, and the S-shaped member 26.

  Based on FIG. 5, the effect exhibited by the positional relationship between the driven wheels 18 of the secondary conveyor device 7b and the drive wheels 10 of the primary conveyor device 7a will be described. A perpendicular line P (indicated by a dotted line in the drawing) as a virtual line extending perpendicularly to the ground from a portion in contact with the scraper 14 at the end of the drive wheel 10 of the primary conveyor device 7a is a secondary conveyor device 7b. Since the rotation shaft 18 of the driven wheel 18 or the diameter of the driven wheel 18 intersects, the primary conveyor device 7a has a base end portion of the secondary conveyor device 7b as compared with the prior art (overlapping dimension A). The overlapping dimension B with the discharge end portion can be minimized, and the belt length of the secondary conveyor device 7b can be configured to the minimum necessary. Thereby, the weight of the secondary conveyor apparatus 7b can further be reduced.

  Further effects will be described with reference to FIG.

  The reason why the chute member 20 and the rubber member 23 are arranged in the vicinity of the driven wheel 18 in the secondary conveyor device 7b is that each of the chute member 20 and the rubber member 23 is in line with the upper surface of the belt 17 in the secondary conveyor device 7b. Since the positional relationship is in contact, the amount of spillage can be reduced while the configuration is simple. Although not shown, the cross section on the upper surface of the belt 17 has a saucer-type shape called a trough as it becomes downstream (discharge end side) of the secondary conveyor device 7b from the driven wheel 18 in the secondary conveyor device 7b. Therefore, when each of the chute member 20 and the rubber member 23 tries to obtain a positional relationship in which the chute member 20 and the rubber member 23 are in contact with the upper surface of the belt 17 in the secondary conveyor device 7b, a complicated shape is required. The present invention can be configured without requiring a complicated shape.

  In the above-described embodiment, even when the inclination of the secondary conveyor device 7b is changed by attaching the height of the S-shaped member so as to be adjustable, the upper end of the S-shaped member and the lower side of the drive wheels of the primary conveyor device 7a. The gap dimension with the part can be minimized.

  If this structure is used, the overlapping dimension of the secondary conveyor apparatus 7b with respect to the primary conveyor apparatus 7a can further be minimized.

  Another embodiment of the present invention may be configured as follows.

  Although not shown, the driving in the primary conveyor device 7a with respect to the perpendicular P with the position of the center axis 19 of the driven wheel 18 in the secondary conveyor device 7b located upstream of the secondary conveyor device 7b as the imaginary line described above. It may be configured to be positioned on the opposite side of the wheel 10. At this time, the center axis 19 of the driven wheel 18 is positioned in the vicinity of the perpendicular line P, that is, within the radial dimension of the driven wheel 18.

  Each embodiment described above is not limited to a self-propelled wood recycler, and can be widely applied to self-propelled processing machines having a conveyor such as a self-propelled crusher, a self-propelled shredder, and a self-propelled soil improvement machine. Needless to say.
