A work vehicle including a drive device () having an internal combustion engine () for driving a vehicle body () has: a first tank () that is disposed in front of or behind the drive device, and stores fuel () to be supplied to the internal combustion engine; a second tank () that is disposed below the drive device so as to be separated from the first tank by a predetermined distance, and stores the fuel to be supplied to the internal combustion engine; a first storage amount detection part () that is disposed in the first tank, and detects an amount of the fuel stored in the first tank; and a second storage amount detection part () that is disposed in the second tank, and detects an amount of the fuel stored in the second tank.

Work vehicle

Vibrating roller

A work vehicle including a tank () formed so as to extend from a rear part of a vehicle body toward a center, wherein the tank includes: a first storage tank () located on the rear side of the vehicle body, and stores stored fluid (); a second storage tank () located on a side close to the center in the front-rear direction of the vehicle body, and stores the fluid; a partition part () that separates the first storage tank and the second storage tank; a discharge member () that has a discharge opening () extending and opened inside the second storage tank, and discharges, from the second storage tank, the fluid stored in the second storage tank; and a hollow tube member () that has a first end communicated with the first storage tank through the partition part so as to enable the stored fluid to flow, and a second end having a hollow tube opening () extending and opened toward the center of the vehicle body inside the second storage tank, wherein the hollow tube opening of the hollow tube member is located on the central side of the vehicle body with respect to the discharge opening of the discharge member.

A work vehicle including: a drive device that has an internal combustion engine for driving a vehicle body; a first tank for storing fuel to be supplied to the internal combustion engine; and a second tank for storing fuel to be supplied to the internal combustion engine; wherein the first tank is disposed in front of or behind the drive device, and the second tank is disposed below the drive device so as to be separated from the first tank by a predetermined distance.

A ROPS (protective structure) () is obtained by coupling upper ends of a pair of leg portions () with a coupling portion () and forming an arc-shaped curved portion () between each of the leg portions () and the coupling portion (), and is arranged so as to straddle vehicle bodies (and) and fixed. A working light () is fixed to the left curved portion () via a mounting bracket (), and a rotary light () is detachably mounted by fixing a mounting bracket (). A protect region (E) formed into an approximately triangular shape is formed by the curved portion () of the ROPS (), a lateral restriction line (L) in which a left-side surface corresponding to a maximum width of the vehicle bodies (and) is extended upward and an upper restriction line (L) in which a maximum height of the ROPS () is extended laterally. The working light () and the mounting brackets (and) are arranged in the protect region (E), thereby preventing an outward protrusion.

Compaction machine

A wood crusher having a crushing apparatus includes a crushing rotor for crushing target wood to be crushed, a second screen detachably mounted on the outer peripheral side of the crushing apparatus and a screen support member disposed on the outer peripheral side of the second screen and holding the second screen in a position on the outer peripheral side of the crushing apparatus. A link mechanism is coupled to the screen support member, and a hydraulic cylinder is coupled to the link mechanism to advance and retract the screen support member relative to the crushing apparatus with extension and contraction thereof. Time and labor required for work of replacing the sieve member can be greatly reduced as a result.

Wood crusher

A self-propelled crushing machine comprises a crushing device; a hydraulic drive system including a crushing device hydraulic motorfor driving the crushing device, a first hydraulic pumpfor driving the crushing device hydraulic motor, and an enginefor driving the first hydraulic pump; a pressure sensorfor detecting a load condition of the crushing device; and a controller&#x2033; for executing control to increase a revolution speed of the enginein accordance with a detected signal from the pressure sensor. Accordingly, even when a heavy load is imposed on the crushing device, a reduction of crushing efficiency can be prevented.

Self-propelling crusher

A wood crusher has body frame; a crushing apparatus installed on the body frame and a crushing rotor rotated in a crushing chamber. A feed conveyor for conveying wood to be crushed is installed on one side of the body frame in the longitudinal direction thereof and includes a drive wheel, a driven wheel, and a running member looped between the drive wheel and the driven wheel. A bottom-equipped hopper having side walls on both sides of the feed conveyor in the transverse direction thereof, and a bottom wall disposed under the feed conveyor has a guide member disposed in continuation with the bottom wall of the hopper at a position near the drive wheel of the feed conveyor to prevent wood pieces from accumulating near the drive wheel. This arrangement prevents the wood pieces from being dropped onto the ground during the crushing work.

Wood crusher and wood treating method

In a self-propelled recycling machine for receiving recyclable materials and processing the recyclable materials to produce recycled products, the self-propelled recycling machine comprises traveling unitsdisposed side by side in a spaced relation, a base framedisposed between the traveling unitsso as to form a space for accommodating a power unitbetween the traveling units, the power unitdisposed in the space within the base frame, and a mixing apparatusdisposed on the base frame. With such a construction, flexibility in layout of various component units can be increased.
