Conventionally, as a compact tractor backhoe to be attached to a tractor, a frame that's detachably attached to the rear a part of the tractor has been provided, and a swing bracket is supported on the rear a part of the frame so on be swingable a few vertical axis. the bottom of the boom is pivotally connected to be swingable about the left and right axis, the arm is pivotally connected to the tip of the boom so on be swingable about the left and right axis, and therefore the bucket is pivoted about the left and right axis. The swing bracket is pivotally connected, and therefore the outriggers are attached to the left and right sides of the frame. The swing bracket, boom, arm, bucket, and outrigger are operated by a hydraulic cylinder, and therefore the step is attached to the upper wall of the frame. At an equivalent time, the control box is fixed on this step, and therefore the swing bracket, boom, Arm, bucket, there's a tractor-mounted compact tractor backhoe control valve formed by accommodating an impact valve which is made by aggregation of controlling the hydraulic cylinder for operating the outrigger.
In this tractor-mounted tractor compact tractor backhoe, the boom cylinder for operating the boom is inserted into the boom, and one end side is pivotally connected to the rear upper a part of the swing bracket, and therefore the arm cylinder for operating the arm may be a bucket cylinder that's disposed along the boom on the side side of the boom and operates the bucket is disposed along the arm on the rear surface side of the arm, and a hydraulic hose that supplies pressure oil to those hydraulic cylinders is connected to the rear surface of the control valve. The boom cylinder pivot support portion and therefore the refore the boom pivot support portion are arranged between the boom cylinder pivot support portion and the pivot support portion of the swing bracket with reference to the frame.
Within the tractor-mounted compact tractor backhoe, the operation are often stabilized by bringing the bottom of the boom as far as possible and bringing the working device including the boom, arm, and bucket forward (closer to the tractor). However, as within the conventional tractor compact tractor backhoe, an impact valve is provided on the top of the frame, and hydraulic hoses for the boom cylinder, arm cylinder, and bucket cylinder are provided at the pivot portion of the boom cylinder provided at the rear upper a part of the swing bracket. If the boom cylinder pivot part and therefore the swing bracket pivot part are inserted into the boom through the boom cylinder pivot part and the boom pivot part after passing between the swing bracket pivot spare reference to the frame, so as to secure the space to pass the hydraulic hose, the bottom of the boom is moved forward. there's a limit to.
Therefore, in sight of the above problems, an object of this compact tractor attachments for sale is to supply a tractor-mounted compact tractor backhoe capable of bringing the bottom of the boom forward.
The technical means taken by this compact tractor attachments for sale uk so as to unravel the technical problem include an upper wall, a lower wall arranged below the upper wall, and a front and rear side extending from the upper wall to the lower wall. A swing that's arranged so on face the direction and includes a vertical wall that connects the upper and lower walls, and is attached to the rear portion of the tractor, and is supported on the rear portion of the frame so on be rotatable a few vertical axis. The boom is swingably supported on the bracket, the arm is swingably supported on the tip end side of the boom, and therefore the bucket is swingably supported on the tip end side of the arm. The swing bracket, boom, arm, bucket And an impact valve formed by collecting control valves for controlling the hydraulic cylinders is provided between the upper wall and therefore the lower wall of the frame.
The control valve could also be attached to the vertical wall of the frame, and therefore the side of the upper wall of the frame could also be a step surface. A boom is supported on the rear lower a part of the frame via a horizontal axis in order that it can swing up and down, and a hydraulic hose that supplies pressure oil to the hydraulic cylinder that operates the boom, arm, and bucket is arranged on the rear side from the control valve. Then, it's preferable to insert it into the boom through the horizontal axis. Further, it's preferable that the boom hydraulic hose, the arm hydraulic hose, and therefore the bucket hydraulic hose are juxtaposed within the left-right direction within the boom.
The left and right side walls extend forward from the left and right ends of the vertical wall, and an outrigger frame for attaching an outrigger is provided on the left and right sides of the left and right side walls. The front and rear walls are spaced aside from one another , and therefore the connecting walls that connect the inner ends of the front and rear walls within the left-right direction are formed. The upper wall and therefore the lower wall are formed of flat plates, and therefore the refore the vertical wall and the left and right side walls Are formed by bending the plate material into a U-shape, and therefore the refore the front and rear walls and the connecting wall of the outrigger frame are formed by bending the plate material into a U-shape.
