The present invention relates to an arrangement of a track 5 for straw bales provided in a rack 6 and intended for being placed between a straw baler 2 drawn by a tractor 1 and a collecting trailer 4 for straw bales. In order to ensure that the straw bales are not piled up in the front portion of the collecting trailer, thereby preventing adequate placing of later bales in the trailer, a bale thrower is according to the invention being used, which comprises a guide rail 8 arranged in the rack 6 in the vertical plane containing the direction of travel of the vehicle, for a slide 9 displaceable along the guiding rail, said slide carrying a horizontal, crosswise directed rod 10 along which pushers 11 are arranged rearwards swingable from vertically downwards directed positions, a hydraulic cylinder 12 able to be coupled to the hydraulic system of the tractor 1, one end of said cylinder being coupled to the rear portion of the guiding rail, and its piston rod 13 being able to be releasably coupled to the slide 9 by means of a releasing device 14, a spring means 15 arranged between the rear part of the guiding rod and the slide, a releaser 16 arranged in the front portion of the guiding rail for the coupling means 14, and also a manoeuvring arm 17 arranged in the way of the straw bale for a valve 18 for the hydraulic oil to the hydraulic cylinder 12, such that the hydraulic cylinder displaces the slide forwards while extending the spring means when the manoeuvring arm is actuated by a straw bale, and when the coupling device 14 reaches the releaser 16, the now extended spring means throws the slide 9 rearwards, whereby the pushers 11, till now deflected rearwards by the straw bale, are swung down against the forward side of a straw bale, throwing it rearwards. <IMAGE> |
