Abstract
Instead of being bound by being wrapped with twine, wire or plastics sheeting, relatively large bales of crop formed by winding are made cohesive by pressing a pushing or penetrating member into the bales as the outer layers are formed. The pushing member forces stalks from each layer of crop into inner layers, to achieve a plaited or braided effect that keeps the bale intact. In another embodiment U-shaped binding elements are shot into the bale for holding the bale together after it has been formed.
Claims45
A baler comprising a pick-up device for picking up crop lying on the ground, and a bale forming space, the baler further comprising means for binding formed bales which comprises means for penetrating peripheral layers of the bale so as to interconnect said layers to provide the bale with sufficient binding cohesion so that there is no need for applying twine, wire, plastic sheet or the like around the bale.
A baler comprising a pick-up device for picking up crop lying on the ground, and a bale forming space, the baler further comprising means for binding formed bales which comprises means for penetrating peripheral layers of the bale to provide the bale with sufficient binding cohesion so that there is no need for applying twine, wire, plastic sheet or the like around the bale, said penetrating means comprising a binding mechanism for displacing a binding element inwardly of the bale thereby to interconnect layers of crops in the peripheral part thereof.
A baler as claimed in claim 61 in which said pushing element comprises star-shaped plates.
A baler as claimed in claim 66 in which said plates project freely as edges at the periphery of said pushing element.
A baler comprising a pick-up device for picking up crop lying on the ground, a bale forming space and a plurality of binding elements for insertion into a bale thereby to secure together several layers of said crop in the bale.
A baler comprising a pick-up device for picking up crop lying on the ground, a bale forming space and a binding mechanism for displacing a binding element inwardly of a bale thereby to interconnect layers of crop in said bale.
