- a transmission system that includes a transmission shaft S extending in a longitudinal direction, having a front end (not visible in the drawings) that is to be connected to the power take-off of an agricultural tractor in order to be driven in rotation by the engine of the tractor.
- the shaft S has a rear end thereof connected by means of bevel-gear pairs 12 to two transverse shafts, which are rotatably mounted within axle casings 13.
- the latter are supported by two lateral supporting walls 14 that project at the front of the lateral structures 7 and are made of a single cast piece therewith.
- the aforesaid lateral walls 14 that project from the lateral structures 7 are connected together by a boxlike cross member 15.
- An end of one of the transverse shafts driven by the transmission shaft 1 1 carries a gear 16, which is connected to a first gear 17 connected in rotation to one of the rollers 5 carried by the load-bearing structure 6 (see Figure 4).
- the device for transmission between the gear 16 and the gear 17 is contained in a casing 18 ( Figures 1 -3) and comprises a transmission shaft, the ends of which are connected in rotation by means of bevel gears to the two gears 16, 17.
- each of the rollers 5 carried by the load-bearing structure 6 is connected in rotation to a respective gear 19 (see Figure 4).
- the gears 19 are connected together in concordant rotation by means of idle gears 20 set between them.
- FIGS 1 , 3, 4 also show that the load-bearing structure 6 supports a roller 5a having the function of feeding a mesh for binding the round bale in the direction indicated by the arrow A illustrated in Figure 1.
- the series of gears 17, 19, 20 that transmits motion to the rollers 5 carried by the load-bearing structure 6 is contained in a casing that is hermetically closed by a lid 21 (see Figures 1 -3) and is made of a single piece with one of the two lateral structures 7 forming part of the load-bearing structure 6 constituted by an aluminium casting.
- the structure 10 that is articulated to the structure 6 comprises a gear transmission arranged on the prolongation of the gear transmission 17, 19, 20.
- Each of the rollers 5 carried by the articulated structure 10 has a respective gear 22 connected in rotation therewith, and idle gears 23 are provided between adjacent gears 22, which enable transmission in series of rotation from one roller 5 to another.
- a roller 5 which, in addition to the respective gear 22, has an auxiliary gear 24 (Figures 3, 4), which is driven in rotation by an idle gear 20, mounted inside an auxiliary casing 25 ( Figures 1 , 2), carried at the top end of the respective lateral structure 7 of the load-bearing structure 6.
- the auxiliary gear 24 is driven in rotation, via the aforesaid idle gear 20, by a last gear 19 of the series of gears carried by the load-bearing structure 6.
- the load-bearing structure 6 envisages a similar casing 25, both of the casings 25 being used for hinging of the articulated structure 10.
- the succession of gears 22, 23 associated to the articulated structure 10 is contained in a casing, which is closed in a sealed way by a lid 26 ( Figures 1- 3) and is made of a single cast piece with the respective lateral structure 9.
- the reference number 29 designates the axis of articulation of the gathering and feeding unit 28 to the front lateral walls 27 of the load- bearing structure 6.
- the two lateral structures 7 forming part of the load-bearing structure 6 and the two lateral structures 9 forming part of the articulated structure 10 consequently constitute, together with the transverse structures 8, 15 that connect them together, a sort of structure of the space-frame type, preferably made of aluminium, which incorporates in a single piece the casings of the gear transmissions 19, 20 and 22, 23 and likewise incorporates in a single piece the walls 14, 27 for supporting the driving transmission and the unit 28 for gathering and feeding the produce.
- the lateral wall 14 represented further to the left in the figures carries a casing 30 of a transmission that receives the motion from one of the transverse shafts driven by the shaft S and transmits it to a transverse drive shaft of the gathering and feeding unit 28.
- the transmission contained in the casing 30 comprises, in a way similar to the transmission contained in the casing 18, a transmission shaft the ends of which are connected in rotation by means of bevel-gear pairs to gears mounted on the connected transverse shafts.
- lateral walls Fixed to the two lateral structures 7 of the load-bearing structure 6 and to the two lateral structures 9 of the articulated structure 10 are lateral walls made of sheet metal 30, 31 substantially in the form of semicircles that close the pressing chamber laterally.
- reinforcement lattices 32, 33 which carry, respectively, a pin 34 and an articulated hook 35 designed to engage mutually in order to block the articulated structure 10 in its lowered condition.
- the pressing chamber is blocked in a closed condition and the produce fed by the unit 28 in the direction of the arrow B visible in Figures 1 and 4 is set in rotation within the chamber until the round bale is formed and is bound by means of a mesh fed in by the roller 5a.
- the hooks 31 a provided on the two sides of the pressing chamber are opened, and the structure 10 is raised to enable unloading of the round bale on the ground.
- the lateral structures 7 forming part of the load-bearing structure 6 are also used for installation of the axle 36 carrying the wheels 2 of the machine.
- the invention described herein applies also to the case where, instead of a ring of rollers 5 of the type described above, the lateral structures of the load- bearing structure and of the articulated structure of the machine carry a limited number of rollers that have the purpose of engaging belts that define a pressing chamber of variable width, which enables round bales of adjustable diameter to be obtained.
- the press has once again a load-bearing structure of the space-frame type as described above, obtained by casting, with a similar structure articulated to the load-bearing structure, but in this case, rotation of the rollers 5 of the pressing chamber (which may be of the fixed-volume or variable-volume type) is driven by means of electric motors present on board the press.
- rollers of the pressing chamber is driven by means of one or more electric motors, but, according to the preferred solution, one electric motor is provided for each roller of the pressing chamber.
- a particularly preferred embodiment envisages providing an electric motor M inside each roller 5, as may be seen in Figure 5, so that each roller 5 becomes a motor-roller. Motors suitable for a use of this type are already known and available on the market.
- each roller 5 is rotatably supported on a shaped body, which is received in a seat 43 in such a way that it can be slid out in a direction substantially perpendicular to the axis of the roller.
- the aforesaid shaped body comprises a prismatic body 40 with a cylindrical axial pin 41 terminating in a widened cylindrical head 42.
- the seat 43 is of a complementary shape and is made in a support 34 fixed to the respective lateral structure 7 or 9. Blocking to prevent the body from sliding out of the seat 43 is obtained by means of engagement of a transverse pin 45 ( Figure 7) through mating holes 46 and 47 of the support 44 and of the prismatic body 40, as may be seen in Figures 6, 7.
- FIG 8 illustrates a final variant of electric motor drive for the rollers 5, in which each roller 5 has an end pin 50, which is rotatably received within a support 7a of the respective lateral structure 7 or 9 and is moreover connected in rotation inside an axial cavity 52 of a tubular shaft 53 of an electric motor M of the direct-drive or torque type.
