Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plurality of plowed soils carried by an elongate frame portion for power drive for rotation about corresponding substantially vertical or at least upwardly extending axes. The tilling members form a row extending in a direction substantially horizontally perpendicular to the working direction of the tilling implement or machine, or at least in a direction transverse to the working direction of the tilling implement or machine. The present invention relates to a tilling implement or machine for filling soil, characterized in that the elongate frame part includes parts of a drive transmission device to the rotary tillage member. Throughout the specification below, for the sake of brevity, the term "instrument or machine" will be shortened to "instrument".

In the case of this type of equipment, through the shaft that carries the tillage member,
Manufacturing and assembly costs tend to be high because extremely high torques need to be transmitted to the tillage component, so the shaft must be carefully, strongly, and extremely accurately supported. . The aim of the present invention is to significantly reduce these costs and therefore to provide a horizontal or nearly horizontal support with a periphery encompassing the axis of rotation of each tillage member at a height lower than the bottom of the frame. It is an object of the present invention to provide a soil cultivating implement of the above type, which is characterized by positioning.

Other features and advantages of the invention will be explained in detail below with reference to the accompanying drawings, which show examples of embodiments.

In the accompanying drawings, the tillage implement shown is of the rotating harrow type, the harrow extending approximately horizontally across the working direction of the harrow, indicated by arrow A in Figures 1.2 and 3. It has a frame portion 1 which extends and generally extends perpendicularly (as shown) substantially horizontally to the direction of work progress. The hollow frame part 1 is made of sheet steel and comprises a lower part of a channel-shaped cross section with arms that diverge upwardly away from a bottom part located approximately horizontally. The upper edge of the upwardly divergent arm is curved generally horizontally in the opposite direction, and a flat force is applied to the curved edge or rim by a plurality of regularly spaced generally vertical small ports. ) <- Hold the plate constant and insert a gas tube between the lower edge or rim of the hollow frame 1 and the top of the cover plate to prevent leakage of oil or other lubricants or entry of wear debris. prevent. Considering the direction A, approximately in the center between the front and rear parts of the elongated plate part 1 is a rotary tilling member 2 located below a row of 12 pieces in this embodiment. Supported. The axis of rotation of each tilling member 2 coincides with the longitudinal axis of a corresponding shaft 3 positioned vertically or nearly vertically, and the axis of rotation is conveniently spaced at intervals of 25 cm and 4 cm from each other. However, this interval is not absolute. With this spacing, the working width of the described implement is approximately 3 meters, and the effective plowing width of each member 2 slightly exceeds the mutual spacing of the longitudinal axes of the adjacent shafts 3, so that the working width of each member 2 is approximately 3 meters. The strips that are formed follow each other to some extent.

Each shaft 3 is surrounded throughout the length of the central main body by a corresponding tube 4, the inner diameter of the wire tube being significantly greater than the diameter of the corresponding shaft 3. The upper end of the container tube 4 extends upwardly through a hole provided in the flat bottom of the lower part of the hollow frame part 1, and a corresponding flange 5 is welded to the upper end. The inner surface of the bottom part of the frame is fixedly and securely secured by a plurality of bolts 6 and 7 (see FIG. 3) spaced apart from each other at regular intervals around the axis of the shaft 3. Releasably secured. The diameter of each shaft 3 is constant throughout substantially its length, and the ends of the shaft 3 project upwardly beyond the upper end of the corresponding tube 4 and below the lower end of the wire tube. The inside of the upper end of the container tube 4 has a stepped structure, the wire membrane receiving the outer race of the corresponding ball bearing 8, and the inner race directly surrounding the corresponding shaft 3. The lower end of the container tube 4 has a similar structure, but
The difference is that in this case the inner stage of the tube 4 extends further inside the tube than the upper stage of the tube, the lower stage accommodates the outer race of the ball bearing 9, and the inner race Here again, the idea is to directly surround the corresponding shaft 3. A spacer sleeve 10 surrounds each shaft 3 between the inner race of the corresponding lower ball bearing 9 and the upper surface of the washer 11, in which case the lower surface of the washer 11 supports the upper end of the hub of the carrier 12 forming a section. Similarly, washer 1
Between 1 and the lower ball bearing 9, an oil seal ring is installed.
Surrounding each spacer sleeve 10, the lower ball bearing is provided below the tube 4 and above the tube 4 by the vertical length of the inner stage of the wire tube.

The hub of each cultivating soil member carrier 12 is located at the downwardly projecting end of the shaft 3.
Tightly and releasably fixed, the carrier surrounds the shaft 3 by means of transverse fastening pins of a structure known per se.

At a position immediately below the midpoint of the container tube 4, the container tube 4 is inserted into a hole provided in a horizontally or nearly horizontally positioned plate 13, in which case the plate 1-13 is located at the bottom of the hollow frame part l. parallel or nearly parallel to

The container tube 4 projects below the plate 3 by a distance equal to or approximately equal to its own outer diameter. For direction A,
The trailing edge of the plate 13 at the rear of the tube 4 is curved so as to extend downward in a nearly vertical direction. Three relatively short bolts 6 and one fairly long bolt 7 correspond to the vessel 4 and the flange 5, and as is clear from Figures 2.3 and 4, the axis of each long bolt 7 The section is surrounded by a spacer sleeve 14 and the bolts 7 serve to help tighten the flange 5 in place and securely connect it to the plate 13. The uncurved leading edge of the play 1-13 in direction A is fixed to the rearwardly curved lower edge of the nearly vertically located front plate 16 by means of a number of small bolts 15, which are located approximately vertically. As is clear from FIG. 2, the upper edge of the plate 16, which is positioned more or less vertically, is curved rearward to connect the upper and lower parts of the hollow frame part 1 to each other. It is fixed to the front rim of the hollow frame part 1 by small bolts. The plates 13 and 16 extend over substantially the entire lateral length of the hollow frame portion 1φ.

The opposite ends of the hollow frame part 1 are closed by parallel, approximately vertically located side plates 17 of generally rectangular shape (see FIG. 2), although not exactly rectangular, the upper edge of each side plate 17 being , is approximately at the same height as the cover plate of the frame part 1, and its front edge is in the direction A with respect to the plate 16.
The rearmost edge is in the same forward position as the frame part 1.
aligned with the rear rim of the plate 1, whose lowest edge is roughly horizontal.
3, well below the bottom of the frame section, at the same level as the end of the downwardly curved trailing edge of each side plate 1.
7 are fixed to the corresponding edges of plates 13 and 16. Each side plate 17, in a position close to its leading edge,
Approximately midway between the uppermost and lowermost edges, it carries a strong, almost horizontal, corresponding rectangular shaft 18, the two rectangular shafts 18 being able to control the comparison of the two side plays 1-17. From the off-center table ml, it aligns approximately horizontally so as to protrude in the opposite direction.

The front end of the corresponding arm 19 of each semi-horizontal elongated shaft 18 is attached to the shaft 18 such that the arm 19 can rotate upwardly and downwardly. Arm 19 has a corresponding plate l
projecting generally rearwardly from the rectangular axis 18 along t;
As shown in FIG. 1, both arms protrude significantly toward the rear of the hollow frame portion 1. Each side plate 17 is provided with an arcuate array of holes 2o equidistant from the corresponding rectangular axis 18 near the inclined edge interconnecting the uppermost and lowermost edges.

Similarly, each arm 19 is provided with holes equidistant from its rectangular axis 18, and as necessary to align the appropriate hole 20 with the hole in the arm, as shown in FIG. , by rotating them upwards or downwards, the rectangular shafts 18
can be releasably fixed at a desired angular setting about the axis.

Next, insert the bolt 21 into the hole of the arm 19 and the selection hole 2o.
Alternatively, other fixtures may be inserted to hold arm 19 at the selected angular setting for the required period of time.

The rearmost end of the arm 19 carries horizontal bearings between which a squirrel cage grounding roller 22 of watermark construction is mounted for free rotation. The longitudinal axis of rotation of the roller 22 is parallel or substantially parallel to a plane that includes the rotation axes of the twelve tilled soil members 2.

The carrier 12 of each tillage member 2 extends from its hub in two opposite directions and integrally carries at the free ends of its two arms a corresponding sleeve-shaped holder 23 which projects downwards. Each holder 23 is configured to receive an upper anchorage of a corresponding flat spring steel tine 24. The two tines 24 of each tilling member 2 are connected to the corresponding tilling member 2.
The tine 24 is configured to be pulled downward and backward to some extent with respect to the working direction (see small arrows in FIGS. 1 and 3), and each tine 24 has a holder 23 at a different protruding position from the holder 23. a plurality of vertically spaced holes or notches are formed to enable the tines 24 to be secured to the holder 23, and a tightening mechanism is provided to secure each tine 24 in a selected protruding position from the cooperating holder 23. Provide pins or other fasteners. Because of this construction, the tines 24 are movable downwardly within the holder 23, compensating for the inevitable wear on the lower ends of the tines, and allowing the tillage implement to operate at maximum plowing depth unless the tines are completely replaced. Avoid such wear that would be impossible.

At the top end of each shaft 3, directly above the corresponding ball bearing 8, a corresponding spur or straight tooth pinion 25 is welded.

The pinions are dimensioned such that the teeth of each pinion 25 engage the teeth of each immediately adjacent pinion 25, such that each pinion 25, shaft 3 and tillage member 2 are connected to the pinion or Each pinion is mounted in the hollow frame part 1 so as to rotate in the opposite direction to the immediately adjacent like assembly. Immediately above one pinion 25 of the center set,
A bevel pinion or crown gear 26 is provided which is housed in a suitably positioned opening formed in the top plate or cover plate of the hollow frame portion l. A bevel pinion or crown gear 26 rotatably surrounds the lower end of the non-rotating shaft 27 by means of upper and lower ball bearings 28;
Although it does not rotate, it is axially aligned with the shaft 3 corresponding to one pinion 25 of the central set.

Most of the length of the non-rotating shaft 27 is housed in a tapered stamped sleeve 31 below a cast gear box 27A, which has an open bottom and has an open bottom.
(The gear box 27A is fixed to the frame part by several small bolts that hold the parts 11i1 together.
It is fixed in such a position that its open bottom is substantially aligned with said opening in the top plate or cover plate of the hollow frame part 1 which primarily houses the bevel pinion or crown gear 26. Such a construction allows for inexpensive manufacture and ease of assembly, since a high degree of precision is not required. An inner double shoulder 29 of the hub of the bevel pinion or crown gear 26 separates the outer races of the upper and lower ball bearings 28 , the inner races of the lower ball bearings 28 having a flange 30 formed at the lowermost end of the shaft 27 . The flange 30 is spaced a very small distance above the top of the corresponding pinion 25 where it is welded to the shaft 3 which is aligned with the non-rotating shaft 27. The inner race of the upper ball bearing 28 is connected to the casting sleeve 3
It comes into contact with the flat bottom end of 1. The uppermost end of the fixed shaft 27 is
The gear box 27A is reduced in diameter and passed through the opening of the sleeve 31.
The end of the shaft 27 is provided with a recess 4J to accommodate a ring 32, which spins out the downward axial movement of the shaft 27.
Ru. In the construction of the embodiment being described, the bevel pinion or crown gear 26 is fixed to one of the pinions 25 by four smooth pins 33 with flanges or heads at their lowermost ends, which 33 is inserted upward through the matching holes of the lower pinion 25 and the upper bevel pinion or crown gear 26, and the flange or head of the pin 33 is formed in an engageable recess formed on the lower surface of the pinion 25. It is rubbed evenly. The upper end of the shank of the pin 33 projects slightly into a downwardly tapered recess formed in the upper surface of the bevel pinion or crown gear 26, and the pin 33 can be held in place by any of several methods. For example, a strong quick-setting adhesive such as cyan acrylic ester or epoxy resin may be used, the upper end of the cough shaft may be welded into the recess, or known articulating joints or anchoring devices (see Fig. ) may also be used. None of these possible methods require a high degree of precision during assembly.

The teeth of the bevel pinion or crown gear 26 are located in the gear box 27A.
At its inner end, the semi-horizontal rotary input shaft 35 is in driving engagement with the teeth of a relatively small beveled pinion 34 carried inside the gear box. An input shaft 35 is rotatably mounted in a set of horizontally spaced ball bearings 36, with a grooved or keyed end of the input shaft extending generally in direction A from the front of gear box 27A.
protrude forward. The end of the rotary input shaft 35 is a telescoping transmission shaft 3 of a structure known per se with universal joints at both ends.
7 (FIG. 1) for driving connection with the rear power take-off shaft of an agricultural tractor or other work vehicle. The vanes 38 (FIGS. 3 and 4) are arranged at a position where they intersect a vertical plane immediately above the pinion 25 and encompassing the axes of rotation of all twelve rototill members 2. It is positioned on one side of the bevel pinion or crown gear 26. The blade 38 is attached to the tip of a support bracket 39 fixed to the flat bottom of the hollow frame part 1 by a set of bolts 41 and a spacer block 40 or a spacer sleeve equivalent thereto.
to weld. As shown in FIG.
is such that the beveled end of the operating head (see FIG. 4), which is closely adjacent to the bevel pinion or crown gear 26, is relative to direction A.
Desirably, the height is 30 mm with respect to a plane that includes all the rotational axes of the 12 special members 2 so as to return to the rearmost position.
Tilt at an angle of °. The last inclined end in the direction of the vanes 38 is formed very close to the outermost surface in the radial direction of the inverted truncated cone of the bevel pinion or crown gear 26 . In front of the blade 38 in direction A, a second blade 42 is provided.
by a set of horizontally spaced bolts 43,
It is fixed to the substantially flat bottom of the hollow fly section 1. As shown in the plan view (FIG. 3), the second blade 42 has an isosceles triangular shape with a straight side and a concave curve on one side, and both curved sides are immediately adjacent to each other. The pinions 25 are shaped so as to match the curvature of the outermost cylindrical surface in the radial direction of each of the two pinions 25 in the set. As shown in FIG. 3, the linear base edge of the vane 42 is located at the forefront in the direction A and at the front of the inner surface of the substantially flat bottom of the hollow frame portion l. Approximately the rear half of the vane 42 slopes upwardly and rearwardly at an angle of about 30° to the bottom of the frame part l from the part fixed thereto (see FIG. 4). The rearmost end of the 1st oblique part of the vane 42 is in a horizontal position approximately half the vertical thickness of the pinion 25, and extends from the tip of the pinion 25 by a distance corresponding to approximately half the radius of one of the pinions 25. Positioned backwards (considering direction A). 2 (1f vanes 42 and 38 supply oil or other lubricant to the gear from inside the hollow frame part 1 through openings in the cover plate of the frame part which mainly houses the bevel pinion or crown gear 26). It acts to guide the lubricant upwardly into the open bottom of the box 27A. In this way, the task of guiding or supplying the lubricant to the gear box 27A is to This is possible because of the arrangement of the vanes 38 and 42 relative to the direction of rotation of the bevel pinion or crown gear 26 (see FIG. 3).

In front or rear view, a connecting member or pedestal 44 having a bow-shaped configuration is mounted at the center of the front part of the instrument, i.e. where the member 44 is secured to the upright anterior play 16. The top of the arcuate connecting member or support leg 44 is in a nearly horizontal position and in parallel relation to the lateral length of the hollow seven-frame portion 1, and the opposite ends of the top are widely spaced apart. It is strongly connected to the top and rear portion of the hollow frame portion 1 by a tie beam 45 which is widened downward and rearward.

A central portion of the connecting member or support leg 44 is provided with a set of horizontally spaced upright projections 46 having at least one set of horizontally aligned holes formed therein. As shown somewhat diagrammatically in FIG. 1, during use of the implement, a pivoting bin mounted in a hole in projection 46 can be mounted on a three-point lifting device of a farm tractor or other work vehicle or on an adjustable lift of a hitch. One end of the length of the upper lifting link is rotatably connected to a quickening member or support leg 44 of the instrument. Similarly, the connecting member or pedestal 44 includes a strong pivot pin 47 (FIGS. 1 and 2) that is generally horizontally aligned near the bottom, and which pivot pin 47 (Figs. Figure) Rotatably connected to the free end of the lower lifting link of the same three-point lifting device or pitch.

During use of the described tillage implement, a coupling member or pedestal 44 is used to connect the implement to a three-point lifting device or hitch at the rear of an agricultural tractor or other propelled vehicle; The rear power take-off shaft of another working vehicle is drivingly connected to the front protruding end of the rotation input shaft 35 of the gear box 27A.

A known telescoping transmission shaft 37 is used for locating the transmission shaft. If it is necessary to adjust the maximum depth that the spring steel or other tines 24 penetrate into the ground during tillage, the bolts 21 can be temporarily removed before starting work, and a suitable separate hole 20 in the side plate 17 can be inserted. can be adjusted by rotating the grounding roller 22 and its arm 19 together as necessary about the aligned end shape axis 1 until it is aligned with the hole in the arm 19.

When the implement is operatively advanced in direction A, the tines 24 of the tillage members 2 penetrate the soil to an adjusted depth, each member 2 being rotated relative to the direction of rotation of said or each immediately adjacent member. In the opposite direction, it rotates at high speed around the axis of the shaft 3. The working width of each tilling member 2 is about 25 cm, and the mutual spacing between the axes of the shafts 3 is such that the strip cultivated by each member 2 is the same as the strip cultivated by the or each member directly adjacent thereto. It is desirable that the interval be such that it overlaps with the top. However, based on legal requirements regarding the maximum width of equipment that can be transported on winter roads,
The dimensions of the shafts 3 and the mutual spacing of the shafts 3 may also be varied. Similarly, the implement having 12 tillage members 2 is by no means limiting, and of course the effective width of the implement will change, but if the number of tillage members 2 is 12 or more, or 12. It may be less than 1.

Since the diameter of the rotating shaft 3 is the same over its entire length, no expensive machining operations are required. Furthermore, since the tube 4 rotationally supports the shaft 3, there is no need for a cast bearing housing, and the tube 4 has a length approximately equal to the diameter of one of the pinions 25, i.e. approximately 25 cm, as shown. Preferably long. In addition to significantly stiffening and reinforcing the hollow frame part, a protective plate 1 is also provided to prevent the equipment from being damaged by stones or other hard objects in the soil while the equipment is in use.
3 and 16 are provided. With the flange 5 already formed with threaded holes 6 and 7, the tube 4 is quickly and easily installed in position. Since the pinion 25 is easily welded to the upper end of the corresponding shaft 3 and the bottom of the gear box 27A is open, it can be formed and assembled in an economical manner. In particular, the non-rotating shaft 27 with the flange 30 at its lower end can be quickly and easily placed into position in the sleeve 31 without the need for complex techniques requiring high precision. Similarly, on the top of one of the pinions 25 an umbrella pinion or crown gear 26
The method of attachment is also a simple and economical method that does not require high precision, and by using known occlusal joints or joints (not shown).Flanged or headed pins 3
