Embodiment approach 1
[0084] [1] Overall composition
[0085] Next, specific embodiments of the crushing device of the present invention will be described in detail with reference to the accompanying drawings. figure 1 is a side view of the wood breaking plant, figure 2 is its rear view.
[0086] This wood shredder is self-propelled, and includes a shredder 1 and a substantially cylindrical drum (rotary drum) 2 that rotates around an axis O2 to supply wood to the shredder 1 .
[0087] In addition, a drum receiving frame for attaching the drum 2 around the axis, a crusher 1, etc. are attached to a chassis (machine body) 3, and a running body 4 is attached to the chassis 3. In addition, a hopper (fixed hopper) 5 is attached to the upper opening of the drum 2 , and wood is supplied into the drum 2 by putting wood into the hopper 5 .
[0088] Crusher 1 as figure 1 and figure 2 As shown, it includes a rotating shaft rotating around an axis O1 extending in the traveling direction of the wood cru...
Embodiment approach 2
[0236] Next, Embodiment 2 of the present invention will be described. In addition, in the following description, the description of the same parts as those already described will be omitted or simplified.
[0237] In the crushing device according to Embodiment 1 described above, the first hydraulic motor 1A is a variable displacement motor capable of changing displacement only by its own pressure.
[0238] In contrast, in the crushing device of Embodiment 2, such as Figure 13 As shown, a solenoid 202 is connected to the first hydraulic motor 201A, and the solenoid 202 is set for setting the change in capacity of the first hydraulic motor 201A.
[0239] When the operator sets the capacity setting switch of the first hydraulic motor 201A on the operation panel to ON, the first hydraulic motor 201A is set to the small capacity side by the solenoid 202, and when the capacity setting switch is set to When off, it is set to the large capacity side. Moreover, the switching of the...
Embodiment approach 3
[0246] Next, Embodiment 3 of the present invention will be described.
[0247] In the above-described second embodiment, the solenoid 202 provided on the first hydraulic motor 201A is provided for the operator to set the capacity of the first hydraulic motor 201A.
[0248] In contrast, in the crushing device of Embodiment 3, such as Figure 15 As shown, the first hydraulic motor 301A is not a motor of the type whose capacity is switched by its own pressure, but a motor of the type whose capacity is switched by exciting the attached solenoid 302 . different.
[0249] As the trigger sensor for switching the capacity of the first hydraulic motor 301A by the solenoid 302, in this embodiment, the pressure sensor 303 is used in the pump line 161A, and the output of the pressure sensor 303 is controlled by the controller 30. process to energize the solenoid 302 .
[0250] The control structure inside the controller 30 is like Figure 16 As shown in the functional block diagram, t...
