Definitions

  • This invention relates to agricultural weeding apparatus of the type capable of removing unwanted vegetation from beds of crops, including vegetable crops such as onions, carrots and the like, and row crops such as cotton, soy bean, seed tomatoes, and the like.
  • a disadvantage of the disclosed apparatus is that when more than one cutting element is provided to give the ability to till more than one row, the apparatus becomes very sensitive to irregularities in the ground level in the respective rows. In extreme circumstances, a particularly low row may not be tilled at all, with the blades of the reciprocating cutter being held above the surface of the soil by the tool bar, the height of which would remain at the operating height determined by the soil level in the other rows.
  • the present invention aims to alleviate the above disadvantages and to provide weeding apparatus which will be reliable and efficient in use. Other objects and advantages of this invention will hereinafter become apparent. Summary of the Invention
  • a weeding apparatus for weeding between multiple rows of a row crop comprising a plurality of cutter hoe blades having substantially horizontally extending cutting edges, said blades being supported in a plurality of carrier means mounted on an elongated support member, said carrier means being spaced apart a predetermined distance along said support member and including drive means for imparting an oscillatory movement to said blades whereby said blade cutting edges are caused to move in an arc between a forward ground engaging position and an upper rearward position above the ground, and ground engaging means pivotally and adjustably mounted on each carrier means to regulate the height of each carrier means and the cutter blades relative to the ground.
  • the elongated support member may comprise a rectangular frame adapted to be connected on one side thereof to the 3-point linkage of a tractor or like prime mover and said carrier means may be mounted, along the other side of the frame.
  • the carrier means may comprise a generally L-shaped casing with the upstanding leg thereof secured to said frame with the ground engaging means connected to the outer end of the horizontally extending leg of the carrier means with the cutter blade depending downwardly through said horizontally extending leg.
  • the drive means for imparting the oscillatory movement to the cutter blade may comprise a hydraulic motor mounted on the upper part of the upstanding leg of a carrier means member drivingly connected to a common drive shaft extending through all the carrier means.
  • the drive shaft is preferably connected through gear means to a cam member connected by link means to the upper end of an arm member supporting the cutter blade at its lower end.
  • the arm member is conveniently pivotally mounted in the horizontally extending leg of the carrier means enclosure member.
  • the cam members or groups of cam members are mounted so that the cutter blades or groups thereof are driven out of phase with each other so as to reduce the load on the hydraulic motor and drive shaft.
  • the weeding apparatus of the invention also preferably includes sensing means attached to said elongated support member for sensing the distance between the outer edge or edges of the cutter blades and the crop in each row to ensure correct lateral positioning of the cutter blades to the crop.
  • the sensing means transmits a signal to actuating means on the support member to move same and correct any lateral deviation of the path of the apparatus through the crop.
  • the sensing means may comprise a pair of highly sensitive wands mounted on the support member and located between adjacent rows of the crop whereby the wands can contact the foliage or stems of the crop plants and transmit lateral movement thereof to an electronic control box which in turn transmits a signal to the actuating means on the support member to move the support member in the required direction and correct the travel path of the apparatus.
  • An alternative sensing means may comprise a sled member engageable with the sides of a furrow between the crop rows and in like manner to the sensing wands transmits any lateral movement of the side members of the sled to the electronic control box.
  • a further sensing means usable in a furrow may comprise a pair of bullet nose shaped members attached to the ends of a pair of arms connected to the control box and operating in similar manner to the sled member.
  • the lateral movement of the support frame may be effected by mounting on each end of the support member a frame support wheel and a disc member engaging the inner side of a furrow, the two discs being adjusted towards each other and "locked" in both furrows against lateral movement therein.
  • Each disc and wheel of a set are fixedly connected to the support frame through a housing carrying a hydraulic cylinder and piston actuated spindle, the outer end of which is connected by linkage to the disc and wheel.
  • the signal from the electronic control box from the sensing means is transmitted to the hydraulic cylinder in known manner for actuation thereof to correct any sensed deviation of the path of the apparatus. Movement of the spindle and attached linkage tends to move the disc and wheel relative to the housing but as both discs are firmly engaged in the furrows against each other there can only be a resultant movement of the support frame relative to each disc and wheel pair.
  • this invention resides broadly in mechanical hoeing apparatus including a supporting frame, ground engaging means adapted to support the supporting frame, a tool arm pivotally mounted to said supporting frame and having a cutting blade mounted at its lower end, and drive means adapted to oscillate said tool arm, said cutting blade having a mounting portion, a cutting portion and a position indicating portion, wherein the location in use of the cutting blade beneath the soil may be monitored, and wherein the cutting edge of said cutting portion is swept forward of said mounting portion in the direction of travel of the hoeing apparatus.
  • the supporting frame takes the form of a rigid member adapted for attachment to a source of motive power such as a tractor or the like.
  • a source of motive power such as a tractor or the like.
  • the supporting frame may be attached to the tractor by a conventional three point linkage or alternatively via a trailer hitch.
  • the apparatus may be self powered and accordingly provided with the necessary drive and control means, or may be pushed by or slung underneath a tractor.
  • the supporting frame may comprise a tool bar adapted to be attached to the tractor and the like and a body portion bearing the tool arm and being supported on the ground engaging means.
  • the tool bar and body portion are preferably interconnected by a linkage permitting limited vertical relative motion between the tool bar and the body portion.
  • the linkage is of a type permitting such vertical relative movement whilst maintaining the vertical orientation of the tool arm, such as may be achieved by the use of a pair of equal length arms describing a parallelogram between their pivot points.
  • the pair of equal length arms consists of a rigid inextensible link pivoted at both ends and a leaf spring link or other flexible member rigidly mounted to one of the tool bar or the body portion, and pivotally mounted to the other.
  • the tool arm is pivotally mounted to the supporting frame and bears a cutting blade mounted at its lower end.
  • the cutting blade is a hoe blade selected from the hoe blades described above. Pivotal mounting of the tool arm may be achieved by any suitable means including a shaft and bushing or bearings.
  • the drive means may take any form consistent with the function of being adapted to oscillate the tool arm.
  • the drive means is selected from the group comprising hydraulic motors or direct power take off from the tractor or the like.
  • the drive means may include a belt, chain or gear train taking power from the preferred ground engaging wheel.
  • the oscillating movement of the tool arm is preferably achieved by coupling the rotary movement of a crank driven by the power source to the tool arm by means of a connecting rod.
  • this invention resides broadly in mechanical hoeing apparatus suitable for use in for hoeing multiple rows of a row crop or the like and including a tool bar, a plurality of hoe assemblies mounted in spaced relationship along said tool bar, and a linkage for attaching said tool bar to the rear or front of a tractor or the like, each of said hoe assemblies including a supporting frame, ground engaging means adapted to support the supporting frame, a tool arm pivotally mounted to said supporting frame, a cutting blade mounted at the lower end of said tool arm, and drive means adapted to oscillate said tool arm, wherein said ground engaging means are steerable such that the hoeing apparatus may track independently of said tractor or the like.
  • the tool bar extends across the full width of the rows to be cultivated in a single pass, the tool bar being preferably adapted to mount a selectable number of hoe assemblies.
  • the tool bar may be articulated in sections, preferably having an articulation for every one or two hoe assemblies.
  • There may be provided a linkage for attaching said tool bar to a tractor or the like, either operated off the 3 point linkage for drawing in the normal manner, or alternatively linked to the front or underbelly of a tractor for pushing thereby.
  • the plurality of hoe assemblies mounted in spaced relationship along the tool bar are preferably of the type described above and having a ground engaging wheel supporting a body portion linked to the tool bar via a resilient parallelogram linkage.
  • the hoe assemblies are preferably of the steerable type and having the steering mechanism of each of the hoe assemblies interconnected such that the hoe assemblies may be steered in concert.
  • the interconnecting member may be provided with universal joints interposed along its length to prevent the outer wheels loading the steering mechanism in response to passage over unevenness in the ground.
  • the apparatus may be provided with accommodation for a second operator to precisely steer the tool bar within the confines of any side drift of a standard 3 point linkage.
  • the 3 point linkage may be modified to increase the available side drift, for example, by the use of universal or ball type joints in the linkage.
  • the amount of permitted side drift may be limited by limit chains interposed between the tractor and the tool bar to prevent the tool bar moving to the extent that, for example, the tractor wheels are fouled.
  • the apparatus is disposed ahead of or under the tractor, similar arrangements may be made for guidance of the tool bar by a second operator.
  • One advantage of the positioning of the tool bar beneath or ahead of the tractor may be that the hoeing apparatus may be configured to remove weeds very close to the crop in the front operation whilst a second apparatus mounted to the rear of the tractor cleans the weeds from irrigation furrows and shoulders in the one operation.
  • the tool bar mounted in front may also remove the necessity for the unproductive counterbalance weights usually required where the tool bar is rear mounted.
  • a self steering system adapted to steer the tool bar within limits under the control of control means responsive to a sensor adapted to locate the correct path for the tool bar.
  • the sensor in this case may take any known form consistent with the function of actuating a steering mechanism to guide the tool bar along the correct path.
  • the sensor may be an electronic or electro-optical device exercising electrical control over an electro-hydraulic steering actuator, sensing means as in the previous embodiment, or may be simply a mechanical follower adapted to follow a wire strung along a representative row and in following the wire provide moving input to an appropriate controlling means for the actuator.
  • the drive means may take any form consistent with the function of driving each tool arm to effect the reciprocating hoe action.
  • the drive means includes a central source of motive power such as a hydraulic pump or power take off point on the tractor, coupled to common or individual activators.
  • the power take off shaft of the tractor may drive a bevel gear box on the tool bar, the bevel gear box in turn driving a shaft substantially parallel with the tool bar and extending to the outermost hoe assemblies.
  • the individual hoe assemblies may draw power from the shaft via, for example, drive chains or the like.
  • each hoe assembly may be provided with its own hydraulic motor adapted to be connected to the central hydraulic pump of the tractor.
  • the shaft be articulated by the incorporation of constant velocity or universal joints in the shaft to prevent loading of the shaft under flexion as the apparatus traverses uneven ground.
  • the hoe assemblies are driven out of phase with one another to keep a reduced and more constant load on the drive, resulting in less wear and a lower power requirement compared with apparatus where the hoes reciprocate in phase. Accordingly, it is preferred that the out of phase motion of the hoes be maintained such as is the case where the driving shaft runs the full length of the tool bar and has sprockets fitted to drive each hoe or at least each pair of hoes. Where the width of the space between the rows permits, it is preferred to provide two hoe assemblies per row, each hoe assembly being adapted to till one side of the crop row. Where the space is too narrow to permit two hoe assemblies side by side, the hoe assemblies may be disposed one behind the other. Alternatively, a single hoe assembly may be provided with a pair of hoe blades, each blade being adapted to till one side of adjacent rows of the crop with the bend or heel in the centre of the area between rows and the hoe blades in close proximity to the row.
  • the hoe blade is mounted on the tool arm such that the tool arm is disposed away from the row by the length of the cutting edge of the hoe blade.
  • This configuration has the advantage of allowing the hoe blade to pass under any overhanging foliage when cultivating crops such as beans, cabbages or the like.
  • the cutting edge of the hoes may be swept backwards away from the tool arm to give a slicing action through the roots of weeds.
  • the toe of the hoe may be swept forward of the tool arm rather than behind to carry any clods, weed foliage and so on away from the rows of young crops.
  • Apparatus in accordance with the present invention may be adapted to till a set number of rows.
  • the configuration of the apparatus may be variable to suit a variety of conditions.
  • the tool bar, drive shafts and other components such as steering mechanism may be provided in add-on lengths such that the number of hoeing elements may be varied up to the limit of the tractor's ability to draw the apparatus.
  • the spacing of tiie hoeing elements along the tool bar may also be variable.

Whilst blades 11 have been illustrated as depending from a single arm 14, they may be incorporated in a stirrup type configuration with the transverse bar of the stirrup constituting the cutter blade, sharpened on both edges.
  • a parallel linkage 28 connected at the upper part thereof to a manually adjusting member 29 and the lower ends of the linkage are connected to a ground engaging skid member 30 adjustable vertically relative to casing 15 through adjusting member 29 so as to ensure that blades 11/12 engage in the ground 31 to the desired depth of approximately *s inch so as to cut the foliage from the weeds at the crown thereof and thus greatly minimise any further growth by the cut weed.
  • the location of pin 24 on cam wheel 23 is at a different peripheral location in the several casings 15 so as to drive the oscillating cutter blades 11/12 out of phase and thus reduce the load on hydraulic motor 19 and drive shaft 18 by not being in ground engagement at the same time.
  • this embodiment incorporates sensing means to sense the lateral drift of the apparatus in use and bring it back to the correct path and obviate damage to the crop.
  • This adjustment of the lateral location of cutter blades 11/12 may be achieved in a number of ways by use of sensor members located on the support frame 5 and adapted to locate the lateral position of the apparatus in relation to the stems or foliage of the crop or the sides of a furrow between rows of crops.
  • sensing means is a pair of highly sensitive wands 32 connected to an electronic control box 33 on support frame 5 through a sensitive axle means 34 whereby on engagement of either wand 32 with the crop foliage or stems a signal is transmitted through the control box 33 to actuating means 35 on support frame 5 to move the support frame 5 and its attached casings 15 laterally in the required direction to correct the path of the cutter blades 11/12 between the crop rows and ensure the correct clearance between the ends of the cutter blades 11/12 and the crops.

Abstract

Une sarcleuse agricole comporte des lames de coupe horizontales (11, 12; 48) montées sur des supports (10, 47) équipés de mécanismes d'entraînement (21, 22, 25; 64, 66, 65). Lesdites lames (11, 12; 48) sont mues par les mécanismes d'entraînement en suivant une trajectoire courbe, de sorte qu'elles oscillent entre une position relevée et une position de pénétration du sol. La profondeur de pénétration est réglée par une roue (42; 57) ou un patin (3) monté de manière réglable sur les supports (10; 47). La roue qui est en contact avec le sol peut être dirigée de sorte que la sarcleuse peut suivre un trajet indépendant de celui du véhicule remorqueur. La profondeur de pénétration est contrôlée par un indicateur vertical sur chacune des lames de coupe horizontales.
