The first pivot point is connected to a first end of the feeder and the second pivot point is connected to the frame of the processing plant for moving the first end of the feeder. The processing plant includes second joining means having a second support arm having a third pivot point and a fourth pivot point a second distance from each other. The third pivot point is connected to a second end of the feeder. The fourth pivot point is connected to the body of the processing apparatus. An actuator moves the feeder between a first position and a second position. ## Claims ### Claim 1 A material processing plant comprising: a frame; a material processing apparatus having a body pivotally connected to the frame; a feeder operable to feed material to the material processing apparatus; a first joining means comprising a first support arm having a first pivot point and a second pivot point positioned a first distance from each other, wherein the first pivot point is connected to a first end of the feeder and the second pivot point is connected to the frame of the material processing plant for moving the first end of the feeder; a second joining means comprising a second support arm having a third pivot point and a fourth pivot point at a second distance from each other, wherein the third pivot point is connected to a second end of the feeder and the fourth pivot point is connected to the body of the material processing apparatus for moving the second end of the feeder; and an actuator for moving the feeder between a first position and a second position. ### Claim 2 (depends on 1) The processing plant of claim 1, wherein the second joining means are arranged to be moved in relation to the feeder and the processing apparatus between the first and the second positions, in which first position the fourth and the third pivot points are located in relation to each other substantially relative in direction of the horizontal plane and in the second position the fourth and the third pivot points are located in relation to each other substantially relative in direction of the vertical plane. ### Claim 3 (depends on 1) The processing plant of claim 1, wherein the second joining means are arranged to move in relation to the feeder and the processing apparatus between the first and the second positions, in which first position the third pivot point is located below the fourth pivot point viewed in relation to the horizontal plane and in the second position the third pivot point is located above the fourth pivot point viewed in relation to the horizontal plane. ### Claim 4 (depends on 2) The processing plant of claim 2, wherein the actuator is pivotably connected to the body of the processing apparatus and pivotably connected to an end of the second support arm at the feeder side for moving the second support arm between the said first and second positions. ### Claim 5 (depends on 2) The processing plant of claim 2, wherein the actuator is pivotably connected to the feeder and pivotably connected to an end of the first support arm at the processing apparatus side for moving the first support arm between the said first and second positions. ### Claim 6 (depends on 2) The processing plant of claim 2, wherein the said first position is the transport position of the processing plant and the second position is the working position of the processing plant. ### Claim 7 (depends on 2) The processing plant of claim 2, wherein the actuator is one of the following: an electric cylinder, a hydraulic cylinder, a pneumatic cylinder. ### Claim 8 (depends on 2) The processing plant of claim 2, wherein the processing plant further comprises locking means for locking the first or the second support arms substantially stationary in the said first and second positions. ### Claim 9 (depends on 1) The processing plant of claim 1, wherein the processing plant further comprises third joining means which comprise a third support arm having a fifth pivot point which is connected to the body of the processing apparatus and a sixth pivot point which is connected to the body of the processing plant for moving a second end of the processing apparatus. ### Claim 10 (depends on 9) The processing plant of claim 9, wherein the third joining means are arranged to be moved in relation to the frame of the processing plant and the body of the processing apparatus between fourth and fifth positions, in which fourth position the vertical distance of the frame and the body is smaller than in the fifth position.
