Description

Cylindrical bale baler for harvesting products

  The present invention relates to a pick-up

  cylindrical baler intended for agricultural grasses and the pressing space of which remains always unchanged during the compression process is formed by entrained conveying members, in the form of cylinders, bands, chains or the like, which constitute the peripheral limit of said space. In balers of this type, the bale of completely formed harvested product is wrapped in tying string. Before the tying process is started, the advancement of the machine is stopped so that the supply of product into the machine is interrupted. Between the stop of the advancement and the restarting, carried out when the unloading of the bale is completed, a relatively prolonged interruption of the operation is necessary. For this reason, it has already been proposed to precede such a baler with a space

  product storage, to allow

  continuously, i.e. without interrupting the advance-

  machine during the tying process.

  Cylindrical bale balers as well

  equipped have in particular the disadvantage that the capa-

  city of the previous storage space, conditioned by

  the duration of tying, has a very unfavorable influence on the di-

  machine mensions. However, it is notably the intro-

  duction, in the pressing space, of the product stored during the relatively long binding time which leads to

  serious operational disturbances. In order to rac-

  shorten tying time and interruption of operation

  mentr it has already proven useful to use, instead of tying

  above by string, an envelope in the form of a composite band

  woven net. However, this does not yet allow

  to obtain continuous operation of the machine.

  The object of the present invention is to create a ma-

  china operating continuously, without stopping, and with as little product storage space as possible in order to avoid disadvantageous forms of construction and to eliminate the risk of seeing operational incidents occur when the product stored is

  introduced into the pressing space.

  This object is achieved according to the invention by the combination

  of the measures, known per se, defined below.

  Associated with the baler is a device which, intended to wrap a finished cylindrical bale of a

  sheathing strip composed of a woven net, is made

  killed by an unwinder, pulling cylinders and a cutting member, which woven net adheres with its overlapping end part to the underlying part and possibly to the grasses passing through the net, and upstream of the pressing space is provided a space product storage, which space is intended to allow harvested product to be received during the wrapping and ejection process and can be separated from the pressing space by closure and transport members. The invention is explained in more detail below using the attached drawing. In the single figure are designated by 1 and 2 parts of the machine casing which at their

  side walls are interconnected

  abutment by means of a coupling bar 3. Part -1 of the casing is fixedly mounted on the machine frame and part 2 can be caused to tilt according to

  the arrow 4 by means of the assembly 5 forming a jack. The espa-

  that of pressing 6 is limited by cylinders 7 arranged all around the pressing space and rotating one next to the other. The supply of the harvested product 8 is carried out by means of a pick-up drum 9 which partly forms the lower limit 10 of a product storage space 11 whose extent in the direction of the machine is limited by walls 12 and upwards by a grid or the like 13. Between the pick-up drum 9 and the feed opening 14 is mounted a controlled withdrawal member 15 which allows the harvested product to be transported in the pressing space 6 On part 1 of the envelope is supported, in the vicinity of the cylinders 7 limiting the space of

  pressing 6, a binding device 16. This is made up of

  essentially killed by a trough 18 carrying the roll 17 of tying net, by members 19 for guiding the net, as well as by a pair of cylinders 20 net pullers and

  a cutting member 21. As soon as a ball 23 is sufficient

  compressed is formed in the pressing space 6, the tying process is triggered, automatically or manually by the tractor operator, depending on the pressing pressure. The pulling cylinders 20 now allow the binding net 24 to engage, passing through the slot 25 between two neighboring cylinders 7, on the outer periphery of the ball 23 and to be driven by the latter. Before the anterior end of the

  tying 24 reaches the entry opening 14,1 'brought in

  harvested product is stopped and the teeth 22 of the

  sample 15 remain in their upper position until

  that, after the completion of the binding process and the unloading of the bale, the pressing space 6 is at

  again closed. During the downtime of the pre-

  15, the harvested product received by the drum collected

  sor 9 is retained in the product storage space 11 to then be brought, in a way by pushing, into the pressing space in order to form a

new ball.

Claims (1)

CLAIM   Cylindrical baler & baler intended for   agricultural grasses and whose pressing space remains   rant unchanged throughout the compression process -is formed by entrained conveying members, in the form of cylinders, bands, chains or the like, which constitute the peripheral limit of said space, characterized by the combination of the following measures, known per se: a) the baler is associated with a device (16) which, intended to wrap a finished cylindrical bale (23) with a sheathing band composed of a woven net (24), is constituted by an unwinder (17) , pulling cylinders (20) and a cutting member (21), which woven net (24) adheres with its overlapping end part to the underlying part and possibly to the grasses passing through the latter; b) upstream of the pressing space (6) is provided a space   product storage (11), which space is for   born to receive, during the wrapping and ejection process, the harvested product and can be separated from the pressing space (6) by closing members and transport (15, 22).
