Description
2340019 A CROP CONDITIONER OF THE TYPE WITH ROTORS FOR AGRICULTURAL WORK
The present invention relates generally to a crop conditioner for agricultural work, and specifically to a conditioner of the type with rotors equipped with flails or cutters rotating around a horizontal axis which is substantially perpendicular to the motion of the crop conditioner.
Such crop conditioners are used in agriculture, in particular to crush the stubble from cereal grasses to prepare it for composting, for the treatment of fallow lands, etc.
Given the operating width of the machine, crop conditioners of this type often comprise several rotors mounted side by side, or arranged in a Vshape to allow adjustment to reduce the width of the machine for transport after the farm work has been completed and prior to running it on public roads.
In practice, the crushing of the stubble is never very satisfactory. For improved results, the farmer must perform several passes over the crop, which increases the operating time and consequently the cost. This invention relates to an improved crop conditioner that performs a 2 thorough job in a single operation.
According to the present invention there is provided a crop conditioner for crushing field stubble from cereals and the like and plants growing on fallow land, of the type with rotors equipped with flails or cutters rotatable about an axis transverse the direction of motion of the crop conditioner in use, having at least two rotors working one behind the other with respect to the said direction of motion.
This configuration results surprisingly in a performance exceeding that which would be expected when compared to two successive passes using a standard twenty rotor crop conditioner. This effect is more pronounced when the rotors, whiqh may be located in respective rows one behind another, are made to rotate at different speeds with the speed of the rearward rotor or row of rotors being at least equal to, and preferably higher than, that of the forward rotor or row of rotors in the direction of motion of the crop conditioner in use.
The reason for this probably comes from the fact that, even before it hits the ground, the field stubble crushed by the f irst rotor or row of rotors is picked up again (the largest elements in particular), and recrushed by the second rotor or row of rotors.
3 In a preferred embodiment there is provided a crop conditioner having two consecutive rows of rotors; however, the invention is not limited to such a configuration, and would apply as well, for even finer work, to a crop conditioner having a third row of rotors behind the second row.
The invention and its implementation will become more clearly apparent from the following description and attached drawings showing, briefly and only as an example, a possible embodiment of the invention.
In these drawings:
Figure 1 is a perspective view of a crop conditioner according to the invention, equipped with two rows of roto:-s located one behind the other; Figure 2 is an enlarged side view, seen in the direction of the arrow II of Figure 1; Figure 3 is a further enlarged view of the rotor-bearing casing shown in Figure 2, shown incorporated in the machine; Figure 4 is a diagram of a rotor equipped with several cutters.
Referring first to Figures 1, 2 and 3, the arrow F shows the direction of forward motion of a crop conditioner generally indicated 1, when drawn by a tractor (not shown), and the letters AV and AR indicate the front and 4 rear of the machine respectively in relation to the motion of the crop conditioner when working.
When the crop conditioner I is working it is coupled to S the tractor by a draw bar 4 and carried by respective front and rear wheels 3, 2; for road transport the crop conditioner 1 is coupled to the tractor by a draw bar 6 and carried by wheels 5, all of this being previously known.
According to the invention, the crop conditioner machine 1 has two rows of rotors, a front row of rotors 7 and a rear row of rotors 8. For simplicity, the cutters or flails of the rotors 7, 8 are not represented in Figures 1S 1 to 3 and there is no specific indication of the number of rotors in each row. For reasons pertaining to mechanical construction, the axial length of the rotors is usually limited to dimensions which facilitate the assembly and mechanical production, and allowing for an easy assembly from elementary modules, one meter-wide, for example, of machines that work on widths of one, two, three, four, etc. meters.
To drive the rotors 7 and 8, a drive shaft 9 that is driven to rotate by the power take-off shaft ofthe tractor (not shown) drives sequential gear boxes 10 and 11 thus transmitting rotary motion to the rotors 7 and 8.
In the illustrated example, the drive to the rows of rotors is transmitted by gear wheels or bevel gears contained in said gear boxes 10 and 11 which drive the drive shafts 12 and 13, 121 and 131 respectively, which, by means of pulleys and belts placed in casings on each side of the crop conditioner 1, will permit transmission of drive to the corresponding rotors.
In Figure 2 is shown, protected in a casing 14 on the corresponding side of the machine, a pulley 15 keyed to the drive shaft 12 and driving via a belt 16, a pulley 17, itself keyed on a shaft (not shown) driving the rotors 7.
Brackets 18 Figures 1 and 2), are used to hitch the machine behind the tractor in the transport position.
The casing 19 which protects the rotors 7 and 8 is shown in more detail in Figure 3, the said rotors rotating in the direction indicated by the arrows f. If desired, it is possible to drive the second rotor 8 in the opposite direction from that of the first rotor 7. This can be achieved simply by suitably adjusting the gear box 11.
of course, the direction of rotation of the rotors can be reversed compared to that indicated in Figure 3.
Referring now to Figures 3 and 4, the rotor 7 is shown rotating around its shaft 7a and bearing cutters 20 mounted and articulated in a known way on the periphery 6 of the rotor 7. Of course, the rotor 8, which rotates about its shaft 8a, is similarly equipped.
According to this invention, for finer work, and depending on the matter to be crushed, the diameters of the rotors 7 and 8 can be designed to be different, the diameter of the rear rotor 8, f or example, being the smallest and equipped with longer cutters, or vice versa. 10 For the usual type of work, the rotor will be at least 170mm in diameter and the cutters will be at least 7mm thick.

A crop conditioner for crushing field stubble from cereals and the like and plants growing on fallow land, of the type with rotors equipped with flails or cutters rotatable about an axis transverse the direction of motion of the crop conditioner in use, having at least two rotors working one behind the other with respect to 10 the said direction of motion.
