    Title: Agricultural machine, equipped with an improved transport device for incorporated products
    Description
    The present invention relates to the field of agricultural machinery and agricultural equipment, in particular mixer or silage mixer type machines, usually intended to prepare feed portions for ruminants based on conditioned products in bale form (hay or other dried feed) or of products stored in silos (silage-fed feed mixer), by often mixing them with additives or other nutritional substances, and then distributing them directly in the feed troughs.
    The invention has for its object to provide an agricultural machine of the aforementioned type, equipped with an improved loading device.
    Various types of mixers or silage mixer-mixers are already known in the state of the art, in the form of a self-propelled vehicle with a loading device at the front, or in the form of a suspended and towed vehicle, with a loading device at the rear thereof.
    Such a machine essentially comprises a tank-type reservoir, mounted on wheels, provided with at least one mixing screw or similar device inside, and externally equipped with a loading device and with a release device.
    More specifically, the loading device consists of a receiving and transporting device, and comprises a cylindrical cutter mounted in a loading head, wherein transport means connect the cutter to the opening of the tub.
    The rotary cutter progressively receives the product stored in the silo or in the bale, usually compacted, and delivers it to the conveyor belt-type transport means, which then brings the product to the tub and delivers it therein.
    The self-propelled silage mixer SPV from the applicant and the pulled mixer PRODUMIXER from PRODUFORT are illustrative examples of such machines.
    The use of a conveyor belt for the supply, however, has several disadvantages, more particularly over time, more in particular: a complex structure with many mechanical movable parts, large space occupied, high price, limited service life of the belt, as well as a problematic reliability and problematic maintenance.
    The present invention has for its object to provide a solution which overcomes at least some of the aforementioned disadvantages, and preferably all of these disadvantages.
    For this purpose the invention has an agricultural machine as subject of the mixer or silage mixer type, self-propelled or intended to be hung behind a tractor vehicle, said machine essentially comprising a mixing tub with at least one mixing screw, preferably with a vertical axis, and a receiving and transporting device comprising a rotary loading cutter and a transporting device for moving the removed product and for loading it into the tub, the agricultural machine being characterized in that the transporting device comprises an active member in the form of a projection motor with a rotation axis which extending parallel to that of the cutter and located between the two respective horizontal interfaces of the highest envelope and of the lowest envelope of the circular cylinder covered by the cutter during its rotation.
    The invention will be better understood with reference to the following description of preferred embodiments given by way of non-limiting examples, with reference to the accompanying schematic drawings in which:
    Figure 1 is a perspective view of an agricultural machine according to a first embodiment of the invention, in the form of a machine to be towed by a tractor, with a pick-up and transport device that is integrated or separately designed, optionally in the form of a removable auxiliary equipment;
    Figure 2 is a view in side view and in cross-section along a plane perpendicular to the axes of the cutter and of the rotor, of the loading head forming part of the receiving and transporting device of a machine according to the invention as it can be retrieved find in figure 1;
    Figure 3 is a top plan view and a cross-sectional view along a horizontal plane comprising the shafts and rotor shafts of the loading head shown in Figure 2;
    Figure 4 is a partial perspective and partially broken-away view of the pick-up and transport device as can be found in Figure 1; and
    Figure 5 is a perspective view of a self-propelled agricultural machine according to another embodiment of the invention.
    Figures 1 and 5, and in part also Figures 2 to 4 illustrate an agricultural machine 1 of the mixer type or silage mixer type, self-propelled or intended to be towed by a tractor vehicle 2.
    This machine essentially comprises a mixing vessel 3 with at least one mixing screw, preferably with a vertical axis, and a receiving and transporting device 4 which comprises a rotating loading cutter 5 and a transporting device for receiving and loading product into the vessel 3.
    According to the invention, the conveying device comprises an active member 6 in the form of a projection motor with an axis of rotation AR extending parallel to this AF of the milling cutter 5, and situated between the two respective horizontal interfaces PHS and PHI of the highest envelope GS and the lowest envelope GI of the circular cylinders covered by the mill 5 during its rotation.
    The invention thus provides a simple and space-saving solution for transport, with a construction and with a function similar to that of the milling cutter 5, and which completes the operation of the latter by joining with it the active members of the device 4 to form.
    In addition, the arrangement of the rotor 6 in the continuity with and in the extension of the cutter 5, preferably arranged behind the latter in the direction of flow of the flux F of the product transported by the device 4, allows efficient transport of the received product between the cutter 5 and the rotor 6. The operation of the cutter 5 can thus be limited to pushing the picked up product in the direction of the rotor 5 (low rotation speed of the cutter possible / speed of the cutter connected only to the recording operation).
    It goes without saying that in order to realize the smallest possible occupied space and to optimize the transfer of the picked up product between them, the cutter 5 and the rotor 6 are mounted radially close to each other, respecting a distance that is a non-interfering effect of these two organs.
    In particular, the cylindrical volumes that are covered by the rotor 6 and by the milling cutter 5 do not interfere with each other, and preferably they are at a minimum distance from each other which allows an efficient passage of the product between the two elements.
    The concept of the "horizontal" is considered in this text in relation to a normal operating position of the machine 1 (on a horizontal surface).
    Preferably the diameter d of the circular cylinder covered by the projection motor 6 is equal to at least half the diameter D of the cylinder covered by the loading mill 5.
    Preferably, and more particularly when the rotor 6 is less long than the cutter 5 (limitation of the space occupied and the weight), the diameter d is substantially equal to the diameter of the base (of the cylinder) of the cutter 5.
    O
    According to a feature of the invention shown in Fig. 2, a feature that also contributes to an optimization of the operation of the device 4, the rotational directions of the loading mill 5 and of the projection motor 6 are identical, i.e. counterclockwise when the aforementioned cutter 5 and the aforementioned rotor 6 are viewed in view with respect to the direction of movement A of the machine 1 and / or of the pick-up and transport device 4 thereof. With this device 4, the flux of the product, initiated by the rotation of the cutter 5, is pushed in the direction of the transport line 9 by the rotor 6, minimizing the loss of power caused by gravity. The rotation of the cutter 5 counterclockwise ensures a good purity of the silo at the level of the substrate.
    As can also be seen from Figure 2, from the viewpoint of the space occupied and of the construction, it is preferable that the rotation axis AR of the projection rotor 6 and the rotation axis AF of the loading mill 5 are both situated in the same horizontal plane when the machine 1 is in the operating position.
    According to a preferred embodiment variant, the longitudinal extension of the projection motor 6 according to its axis of rotation AR is smaller than that of the loading mill 5 according to its axis of rotation AF. A means or means 7, 7 'for converging and orienting the flux F of the picked-up product is or are preferably provided at the cutter 5 and / or between the latter and the rotor 6, the center of the rotor 6 is preferably shifted laterally, in the direction of the rotation axes AR and AF, with respect to the center of the cutter 5.
    As can be seen from Figures 3 and 4, the length of the projection motor 6 in the AR direction can preferably be between 1/2 and 1/3 of the length of the cutter 5 in the AF direction, with the rotor 6 situated is in line with the cutter 5 in the direction AF, and shifted backwards with respect to the direction of movement A.
    The convergence means can for instance comprise bending walls 7 which are provided in the part of the crankcase 8 'that surrounds the cutter 5.
    Alternatively or additionally, these convergence means may include arrangements 7 'of blades of the milling cutter 5 configured to force the picked-up product in the direction of the rotor 6, while the blades themselves may additionally have specific orientations ( as a function of their situation on the mill 5) so as to orient the flux F. The blades are arranged, for example, in a spiral.
    Taking into account the reduced dimensions of the rotor 6, it is preferable that the linear peripheral speed of the projection motor 6 is greater than that of the loading mill 5.
    The ratio between the linear speeds of the rotor 6 and the cutter 5 may, in particular, depend on their relative dimensions, on the type and amount of product taken up, on the length and orientation of the pipe 9, and on the mutual relative arrangement. The two speeds can, incidentally, be independent of each other and be controlled separately, or can depend on each other in a constructive manner.
    According to an interesting constructional configuration which can be found in figures 1, 4 and 5, the receiving and transporting device 4 comprises on the one hand a loading head 8 which is formed by a first part of the crankcase 8 'in which the loading mill 5 is mounted, and a second part of the crankcase 8 in which the projection motor 6 is mounted, and on the other hand a transport line 9 or trough which is substantially vertical and which ends on an ejector elbow 9 ', wherein a discharge opening 10 of the second part 8 of the crankcase of the loading head 8 is connected to the input 10 'of the transport line 9.
    According to an optimized arrangement, the projection motor 6 is provided below the input 10 'of the transport line 9, the main projection zone determined in combination with the crankcase 8' of the loading head 8 substantially coinciding with the aforementioned input 10 '.
    In order to promote the passage through the head 8 and the ejection from the latter, the second part of the crankcase 8 can comprise a bottom wall 13 which cooperates with the rotary cutter 5 and with the projection motor 5 for transporting and ejecting the picked up product .
    This bottom wall 13 preferably comprises, on the one hand, a first section 13 'which extends along a plane that shows a slight inclination with respect to the horizontal and is substantially tangent to the circular cylinders covered by the cutter 5 and by the rotor 6, below the latter, and on the other hand a second section 13 which is not curved and which extends around the part of the cylinder covered by the rotor 6 corresponding to an angular sector of the basic circle of the cylinder, and finally a third section 13 ' which extends according to another interface on the cylinder covered by the rotor, which has a strong inclination with respect to the horizontal and is preferably situated in the vicinity of the vertical, these three sections 13 ', 13, 13' being mutually continuous and optionally formed from a single piece, the third section 13 'being connected in a coplanar and continuous manner to one of the walls of the transport line 9 at a high from its input 10 '.
    In order to be able to produce a focused and directional product beam with a relatively limited cross-section, the cross-section of the transport line 9 is more limited at its outlet than at its inlet 10 '.
    The transport line 9 is preferably formed, viewed in the direction of the flux F, by a first part 11 which is substantially straight and whose cross-section decreases progressively from the inlet 10 which is connected to the outlet 10 of the crankcase 8 ' 8 from the loading head 8, and through a second curved portion 9 'that forms the ejector elbow.
    The sequence of cross-sectional reductions of the passage between the entrance of the recording head 8 and the exit of the elbow 9 'of the ejection trough 9 allows an important concentration of the product which can thus be taken up over a large width.
    As can be seen from Figures 2 and 3, which are representations of an interesting practical embodiment, the rotor 6 can consist of a drum 12 provided with radial wings 12 ', whether or not of a single piece over the entire axial length of the rotor 12, and for example in the form of inverted chevrons, wherein the rotational movement of the rotor 6 is supplied by a specific rotary actuator 14 associated with the rotor 6, or by the rotary actuator or drive means 14 'which drive the rotational movement of the loading mill 5 .
    The milling cutter 5 can also comprise a drum on which arrangements of knives are mounted (e.g. spiral-shaped).
    The actuators 14 and 14 "are preferably mounted on the respective ends of the rotor 6 and of the cutter 5, located on the same side and substantially mutually aligned.
    It is self-evident that the invention is not limited to the embodiments described and shown in the accompanying drawings. Changes remain possible, in particular with regard to the structure of the various elements or in the form of technically equivalent substitutions, and this without going beyond the scope of the invention.
