A large crop material bale handler mountable to a prime moving vehicle operable to retrieve, transport and discharge large crop material bales is provided with a main support frame, a traveling load support with material engaging elements fastened to the lower portion thereof, power lifting apparatus to raise and lower the load support, and grappling members pivotally affixed at a pivot point to the load support and extending outwardly and downwardly therefrom. The grappling member has a material engaging end and an opposing end. The pivot point further overlies the plane of the material engaging elements such that when the grappling member is in the engaged position the material engaging end, in combination with the material engaging elements, exerts a grappling and lifting force on a bale.

Bale handling means

Apparatus in a crop roll forming machine for improving the core formation of the crop rolls, reducing the amount of particles of crop material lost, and collecting particles of crop material lost from either the crop package or loose crop material during the roll formation process comprising stripping surfaces and an elongated tailgate with a collection pan. The particles are recycled from the collection pan back into the roll forming region by the cooperative interaction of the tailgate collection pan and the upper bale forming means as the bale forming means traverses a predetermined path imparting rotative motion to the crop material delivered to the roll forming region.

Collection and recycling apparatus for crop material particles in a roll

An improved twine wrapping mechanism is provided for a roll forming machine having a frame defining a roll forming region. The twine wrapping mechanism includes an elongated dispensing tube and means for mounting the dispensing tube forwardly of the bale forming region on the frame such that the tube can be driven in a predetermined path across the bale forming region. The tube is fastened at one end to a gear segmented plate which is supported on one end of a shaft rotatably mounted on the frame. The dispensing tube is adapted to be driven along its predetermined path either manually by a handle having a gear segment that driveably mates with the gear segmented plate or automatically by a hydraulic cylinder that is operably connected to the shaft that rotatably supports the plate and the tube.

For facilitating the grinding of clumps of crop material by a hammermill mechanism mounted below an opening formed in a stationary bottom wall of a tub grinder machine, an elongated plate is mounted to the bottom wall along a crop material receiving edge of the opening therein. A longitudinal marginal edge portion of the plate is bent downwardly at a slight acute angle relative to the plane of the mounting portion of the plate so as to extend into the opening generally toward the hammermill mechanism. The bent edge portion of the plate has a series of spaced apart notches or spaces formed therealong which gradually widen toward the edge of the plate so as to define a series of spaced apart, tapered and generally co-planar teeth which facilitate the ability of hammer elements of the hammermill mechanism to disintegrate crop material clumps passing through the opening over the teeth and strip disintegrated material residue from the teeth.

Mixing apparatus having a frame on which a vertical mixing tank is mounted. The tank has a cylindrical upper section and a conical downwardly converging lower section. A hammermill is carried on the frame and provided with a hopper to receive feed material. Different types of feed material are fed into the hopper and chopped as they pass through the hammermill. A transfer auger conveys chopped material from the hammermill to the tank. Other feed material may be added during the mixing operation by introduction thereof via a second auger conveyor. A mixing assembly within the tank circulates the various feed material in a circuitous path to produce a well mixed homogeneous mass. A third auger conveyor, utilized to unload the tank, is mounted coaxially with the second feed auger and communicates with the bottom of the tank through an appropriate opening. The mixing assembly includes a vertical auger having a frusto-conical shaped lower core portion mounted for rotation opposite the conical wall section to form a trough-like area at the bottom of the tank chamber.

Feed material mixing apparatus

Mixing apparatus having a frame on which a mixing tank is mounted and extending vertically. A hammermill carried on the frame receives and chops different types of feed material. The resulting product is then deposited in a transfer conveyor which transports the material to the mixing tank. A mixing assembly within the tank circulates material to produce a well mixed homogeneous mass. The mixing assembly comprises upper and lower material advancing portions, the lower of which includes a conical shaped core member converging upwardly. One or more rigid crop engaging elements extends outwardly from the lower edge of the core member to enhance the effectiveness of the mixing apparatus.

An apparatus for handling large round bales or the like includes a mobile frame adapted for movement across a field and a bed assembly mounted thereon. The bed assembly includes a plurality of elongated, laterally spaced rails capable of being disposed in an inclined position with respect to the frame in which forward ends of the rails are disposed adjacent the field. A flexible endless conveyor chain is movably mounted on and along each rail and has bale-engaging lugs moving along a path extending along and above an upper side of each rail and around and beyond the forward end of each rail for delivering a bale or the like from the field to the forward ends of the rails when the rails are disposed in the inclined position. A ground engaging element is attached to and extends along and below each forward rail end for supporting the rail end above the field. Each element has an opening therethrough for allowing passage of the chain and lugs and engagement of the lug with the field for facilitating insertion of the rail end under the bale as the apparatus is moved across the field in the direction of the bale.
