Description

Technical Field

[0001] This invention relates to the field of agricultural land preparation and sowing machinery technology, and in particular to an anti-clogging rotary tillage, ditching, precision fertilization and sowing integrated machine. Background Technology

[0002] Rotary tillage, fertilization and seeding integrated machines are usually tractor-driven and powered. They integrate rotary tillage, furrowing, fertilization, seeding and soil covering and compaction structures on a carrier frame. The rotary tillage blades first cut and turn the soil in the field, then the furrow opener opens the seed furrow, the seed and fertilizer dispensing structures transport the seeds and fertilizer to the seed furrow area, and finally the soil covering and compaction structure completes the furrow backfilling and surface compaction.

[0003] When operating in fields with high levels of straw, grass roots, and tree roots, the rotary tiller blades rotate continuously with the blade shaft and repeatedly come into contact with fibrous entanglements. Grass roots and tree roots easily become entangled on the outside of the rotary tiller blades or blade shaft. As the entanglements gradually accumulate, they increase the rotary tillage load and affect the soil discharge of the blade rollers. At the same time, there may still be clumps and intertwined roots and stems in the soil after rotary tillage, making the soil entry resistance of the subsequent disc furrow opener unstable, which in turn affects the continuity of fertilization and sowing positions.

[0004] Existing equipment relies heavily on manual cleaning after shutdown to handle entangled material on the cutter rollers. However, adding a separate soil-removing component would easily increase the size of the equipment and add transmission links. Therefore, an integrated structure is needed that can dynamically pull away entangled material during rotary tillage and use shared reciprocating motion to remove soil from subsequent work areas.

[0005] Therefore, it is necessary to invent an anti-clogging rotary tillage, ditching, precision fertilization and seeding integrated machine to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an anti-clogging rotary tillage, ditching, precision fertilization and seeding integrated machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging rotary tillage, ditching, precision fertilization, and seeding integrated machine, comprising a support frame, wherein a rotary tillage mechanism, a reciprocating anti-clogging soil clearing mechanism, a disc ditching precision fertilization and seeding mechanism, and a soil covering and compaction mechanism are sequentially installed on the support frame from the traction end to the rear. The rotary tillage mechanism comprises a rotary tiller frame fixed on the support frame and a cutter shaft rotatably mounted on the rotary tiller frame. Multiple rotary tillage blades are spaced apart on the cutter shaft, and anti-winding baffles are fixedly provided on the sides of the rotary tillage blades, with clearance gaps formed between the anti-winding baffles on adjacent rotary tillage blades.

[0008] The reciprocating anti-clogging and soil-clearing mechanism includes a working support fixed to the rear of the rotary tiller frame, a swing arm support beam fixed to the working support, a reciprocating transmission seat slidably installed on the working support and moving back and forth along its length, and a soil-clearing tooth mounting frame fixed to the reciprocating transmission seat. Multiple swing unclogging rods that are misaligned with the rotary tiller blades are hinged to the swing arm support beam. The reciprocating transmission seat extends upward to form a transmission plate. The transmission plate is movably connected to the swing unclogging rods through multiple transmission arms. Multiple soil-clearing teeth are fixedly installed on the soil-clearing tooth mounting frame.

[0009] The working end of the swing clearing rod is located between adjacent rotary tillers. The movement trajectory of the swing clearing rod and the loosening teeth passes through the clearance gap and is offset from the rotation trajectory of the rotary tillers.

[0010] Preferably, a rotary tiller protective cover is fixedly installed on the rotary tiller frame, and the rotary tiller protective cover is placed above and behind the cutter shaft and rotary tiller blades.

[0011] Preferably, multiple swinging clearing rods are arranged at intervals along the extension direction of the swinging rod support beam, and the swinging clearing rods correspond to the areas between two adjacent rotary tillers. The swinging clearing rods and the soil-dredging teeth are staggered on the working support and their movement trajectories are separated from each other.

[0012] Preferably, a linear guide structure is provided between the working support and the reciprocating transmission seat. The guiding direction of the linear guide structure is parallel to the length direction of the working support, and the reciprocating transmission seat slides horizontally back and forth along the linear guide structure.

[0013] Preferably, both ends of the transmission arm are rotatably connected to the transmission plate and the swing unblocking rod via universal joints.

[0014] Preferably, a drive wheel is rotatably mounted on one end of the working support, and a drive swing arm is eccentrically hinged to the drive wheel. The end of the drive swing arm away from the drive wheel is hinged to a reciprocating transmission seat. The drive wheel is connected to an external drive source through a gear transmission box and a belt.

[0015] Preferably, the soil dredging tooth mounting frame has multiple mounting slots, and the mounting end of the soil dredging tooth is provided with a soil dredging tooth mounting seat. The soil dredging tooth mounting seat is installed in the corresponding mounting slot and fixed on the soil dredging tooth mounting frame.

[0016] Preferably, the end of the soil dredging tooth away from the soil dredging tooth mounting seat forms a soil dredging tooth head, and the soil dredging tooth head and the soil dredging tooth are integrally formed.

[0017] Preferably, the integrated machine also includes a tractor and a traveling support wheel rotatably mounted on a support frame. The traction end of the support frame is mounted to the rear of the tractor through a three-point suspension structure. The cutter shaft is connected to the power output end of the tractor through a shaft transmission structure. The drive wheel is connected to the power output end through a gear transmission box and a belt.

[0018] Preferably, the disc-grooving precision fertilization and sowing mechanism includes a seed box, a fertilizer box, a precision seed metering device, a fertilizer metering device, a conveying pipe, and a disc furrow opener; the soil covering and compaction mechanism includes a cage-type compaction roller rotatably mounted on a support frame and located on the rear side of the disc-grooving precision fertilization and sowing mechanism.

[0019] The technical effects and advantages of this invention are as follows: 1. This invention provides an anti-winding baffle on the side of the rotary tiller blades and creates a clearance gap between adjacent anti-winding baffles. This allows grass and tree roots that come into contact with the rotary tiller blades during rotary tillage to be blocked and guided by the anti-winding baffles. Then, the swinging clearing rod located between adjacent rotary tiller blades passes through the clearance gap and pulls the roots periodically. This removes the tangled material from the rotary tiller blades and reduces the continuous accumulation of tangled material on the blade rollers. This helps to reduce rotary tillage load fluctuations and improve the stability of continuous operation. 2. This invention, through the cooperation of reciprocating transmission seat, transmission plate, transmission arm, soil loosening tooth mounting frame and soil loosening tooth, enables the same reciprocating motion of the reciprocating transmission seat to be converted into the swing of the swinging clearing rod through the transmission plate and the transmission arm with universal connection at both ends. On the other hand, it directly drives the soil loosening tooth to pass through the clearance gap for horizontal reciprocating soil loosening. The linear guide structure limits the motion direction of the reciprocating transmission seat, and the motion trajectories of the swinging clearing rod and soil loosening tooth are separated from each other and avoid the rotation trajectory of the rotary tiller. Therefore, dynamic clearing and soil loosening can be completed simultaneously while sharing the transmission path, and motion jamming and rigid interference are reduced. 3. This invention integrates a rotary tillage mechanism, a reciprocating anti-clogging and soil loosening mechanism, a disc-type precision fertilization and seeding mechanism, and a soil covering and compaction mechanism on a support frame along the working direction. This allows the soil to pass through rotary cutting and crushing, removal of entangled materials, reciprocating loosening, disc ditching, precision fertilization and seeding, and soil covering and compaction in sequence. The soil loosening teeth can reduce the impact of root and stem intertwining and soil clod accumulation on the soil entry of the disc ditcher, thereby providing a more stable soil working foundation for the subsequent seed and fertilizer delivery and soil covering and compaction processes.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the anti-clogging rotary tillage, ditching, precision fertilization and seeding integrated machine provided by the present invention essentially utilizes the same reciprocating transmission structure to form a swinging clearing action and a horizontal soil loosening action, so as to cooperate with the rotary tillage process of the rotary tillage to complete the separation of entangled materials and the subsequent soil loosening.

[0032] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0033] To facilitate the explanation of the relative positions of each structure, in this embodiment, the side where the tractor 12 is located is taken as the front side and traction end of the integrated machine, the side where the soil covering and compaction mechanism 5 is located is taken as the rear side of the integrated machine, and the extension direction of the cutter shaft 22 is taken as the lateral direction of the integrated machine. Subsequent orientation descriptions are based on this directional reference.

[0034] The integrated machine in this embodiment includes a support frame 1. The support frame 1 is equipped with a rotary tillage mechanism 2, a reciprocating anti-clogging and soil-dredging mechanism 3, a disc-type precision fertilization and sowing mechanism 4, and a soil covering and compaction mechanism 5, which are installed sequentially from the traction end to the rear. The support frame 1 is composed of profiles, plates and reinforcing parts welded together to form an integral frame that can withstand the reaction force of each working mechanism. Each working mechanism is installed on the support frame 1 by existing bolt connections, bearing supports and welding fixation methods.

[0035] The traction end of the support bracket 1 is connected to the rear of the tractor 12 through a three-point suspension structure commonly used in agricultural machinery. The three-point suspension structure includes an upper suspension connection position and two lower suspension connection positions. Each connection position is connected to the upper and lower pull rods of the tractor 12 through suspension pins. The hydraulic lifting system of the tractor 12 drives the support bracket 1 to rise and fall through the upper and lower pull rods, thereby lifting the integrated machine during relocation and lowering each working component to the set soil depth during operation. The dimensions and pin fit of this three-point suspension structure are implemented using existing technology without adding any additional reference numerals.

[0036] The traveling support wheel 11 is rotatably mounted on the bearing bracket 1. The wheel hub and the mounting shaft are rotatably supported by existing bearings. The traveling support wheel 11 rolls in contact with the ground during operation, and is used to bear part of the weight of the machine and cooperate with the three-point suspension structure to maintain the working height of the bearing bracket 1. Its installation height can be adjusted by existing multi-hole fixing structure.

[0037] The rotary tillage mechanism 2 includes a rotary tiller frame 21, a cutter shaft 22, rotary tillage blades 23, an anti-winding baffle 24, and a rotary tillage protective cover 25. The rotary tiller frame 21 is fixedly installed on the support bracket 1. The cutter shaft 22 is arranged laterally along the integrated machine and is rotatably supported by bearing seats located at both ends of the rotary tiller frame 21. Multiple rotary tillage blades 23 are installed at intervals along the axial direction of the cutter shaft 22. The rotary tillage blades 23 are staggered in the circumferential direction of the cutter shaft 22 according to the rotary tillage operation range. The rotary tillage protective cover 25 is fixed to the rotary tiller frame 21 and covers the cutter shaft 22 and the rotary tillage blades 23 above and behind to limit soil scattering during rotary tillage and isolate the rotation area.

[0038] The cutter shaft 22 is connected to the power output end of the tractor 12 through the existing shaft drive structure. The shaft drive structure consists of a universal drive shaft, a coupling, a rotary tiller gearbox, and a bearing housing. The input end of the universal drive shaft is detachably connected to the power output shaft of the tractor 12, and the output end is connected to the cutter shaft 22 after being reversed and decelerated by the rotary tiller gearbox, so that the output torque of the tractor 12 is stably transmitted to the cutter shaft 22. The model, transmission ratio, and protection method of the above-mentioned shaft drive components are selected according to the existing rotary tiller technology and no additional reference numerals are added.

[0039] The anti-winding baffle 24 is fixed to the side of the corresponding rotary tiller 23. It is connected to the rotary tiller 23 by welding or bolting. The extension direction of the anti-winding baffle 24 is coordinated with the cutting motion of the rotary tiller 23. When grass roots and tree roots have a tendency to entangle, it blocks and guides them. A clearance is maintained between the anti-winding baffles 24 on adjacent rotary tillers 23. The size of the clearance is larger than the corresponding passing parts of the swing unblocking rod 33 and the soil loosening tooth 36 to ensure that the two do not have a rigid collision with the anti-winding baffle 24 during reciprocating operation.

[0040] The reciprocating anti-clogging and soil-dredging mechanism 3 includes a working support 31, a swing rod support beam 32, a swing clearing rod 33, a reciprocating transmission seat 34, a transmission plate 341, a transmission arm 342, a drive swing arm 343, a drive wheel 344, a soil-dredging tooth mounting frame 35, and soil-dredging teeth 36. The working support 31 is fixed to the rear of the rotary tiller frame 21 by bolt fastening or welding. The two ends of the working support 31 provide fixed support points for the reciprocating transmission structure, so that the tensile reaction force of the swing clearing rod 33 and the soil resistance of the soil-dredging teeth 36 are transmitted to the rotary tiller frame 21 and the supporting support 1 through the working support 31.

[0041] The swing arm support beam 32 is fixed on the working bracket 31. Multiple swing unblocking rods 33 are arranged at intervals along the extension direction of the swing arm support beam 32. The connecting end of each swing unblocking rod 33 is rotatably connected to the swing arm support beam 32 through a hinge shaft. The working end extends towards the area where the rotary tiller 23 is located. The multiple swing unblocking rods 33 and the multiple rotary tiller 23 are staggered so that the working end of each swing unblocking rod 33 is located between two adjacent rotary tiller 23. The swing amplitude of the swing unblocking rod 33 is jointly limited by the stroke of the reciprocating transmission seat 34 and the connection position of the transmission arm 342.

[0042] The reciprocating transmission seat 34 is arranged along the length of the working support 31. An existing linear guide structure is provided between the working support 31 and the reciprocating transmission seat 34. In this embodiment, the linear guide structure consists of a linear guide rail fixed to the working support 31 and a slider fixed to the reciprocating transmission seat 34. The slider slides back and forth along the linear guide rail and restricts the up-down and back-forward offset of the reciprocating transmission seat 34, so that the movement trajectory of the reciprocating transmission seat 34 is kept as a horizontal reciprocating trajectory along the length of the working support 31. The linear guide rail and the slider adopt the existing dustproof linear guide pair and no additional reference numerals are added.

[0043] The transmission plate 341 extends upward from the reciprocating transmission seat 34. Multiple transmission arms 342 are correspondingly arranged with multiple swing unblocking rods 33. The two ends of each transmission arm 342 are rotatably connected to the transmission plate 341 and the corresponding swing unblocking rod 33 through existing universal joints. The universal joints are composed of intersecting rotating shafts and bearing supports, so that the transmission arm 342 can adapt to the angle change of the swing unblocking rod 33 when the reciprocating transmission seat 34 outputs horizontal displacement, thereby reducing the jamming and sticking at both ends of the transmission arm 342 due to different trajectories.

[0044] The drive wheel 344 is rotatably mounted on one end of the working bracket 31 via a rotating shaft and bearing seat. An eccentric connection position is provided on the drive wheel 344, which is offset from its rotation center. One end of the drive arm 343 is rotatably connected to the eccentric connection position via a pin, and the other end is hinged to the reciprocating transmission seat 34. When the drive wheel 344 rotates continuously, the eccentric connection position runs around the center trajectory of the drive wheel 344, and pushes and pulls the reciprocating transmission seat 34 through the drive arm 343. The reciprocating transmission seat 34 is restricted to horizontal reciprocating motion by the linear guide structure. The eccentricity of the drive wheel 344 determines the basic stroke of the reciprocating transmission seat 34.

[0045] The drive wheel 344 is connected to the power output end of the tractor 12 via the existing gear transmission box and belt. The gear transmission box reverses the rotational power output by the tractor 12 and adjusts the speed. The belt is wound between the output pulley of the gear transmission box and the input pulley of the drive wheel 344, which are coaxial. The pulley rotation support, belt tensioning and safety protection structure are all implemented using existing agricultural machinery transmission technology without adding any additional reference numerals. This transmission branch is matched with the shaft transmission branch of the cutter shaft 22 to ensure that the rotary tillage speed and reciprocating clearing frequency can be set according to actual operation requirements.

[0046] The soil dredging tooth mounting bracket 35 is fixed on the reciprocating transmission seat 34. Multiple mounting slots 351 are opened at intervals along the extension direction of the soil dredging tooth mounting bracket 35. Each soil dredging tooth 36 is provided with a soil dredging tooth mounting seat 361 at its mounting end. The soil dredging tooth mounting seat 361 is installed in the corresponding mounting slot 351 and fixed to the soil dredging tooth mounting bracket 35 by the existing bolt fastening structure. The mounting slot 351 limits the lateral position of the soil dredging tooth mounting seat 361 and bears part of the lateral force generated when the soil dredging tooth 36 is working. The soil dredging tooth 36 can be stably installed without adding new markings.

[0047] The soil-dredging tooth 36 is formed by processing wear-resistant metal material. The end of the soil-dredging tooth 36 away from the soil-dredging tooth mounting base 361 forms a soil-dredging tooth head 362. The soil-dredging tooth head 362 is integrally formed with the soil-dredging tooth 36. The soil-dredging tooth head 362 constitutes the working end that directly cuts into and moves the soil. The integrally formed structure allows the soil force to be continuously transmitted along the soil-dredging tooth 36 to the soil-dredging tooth mounting base 361 and the soil-dredging tooth mounting frame 35, reducing the loosening of the connection between the working end and the tooth body.

[0048] The swinging unblocking rod 33 and the soil-dredging teeth 36 are staggered along the front-back and up-down directions on the working support 31. Their movement trajectories are separated from each other. The passing parts of the swinging unblocking rod 33 and the soil-dredging teeth 36 correspond to the clearance gap between the adjacent anti-entanglement baffles 24. A safe gap is maintained between each movement trajectory and the rotation envelope area of ​​the rotary tiller 23, so that the swinging unblocking rod 33 can act on the entanglement between the adjacent rotary tillers 23, and at the same time, the soil-dredging teeth 36 can reciprocate to move the soil layer after rotary tillage without colliding with each other.

[0049] The disc-type precision fertilization and sowing mechanism 4 adopts the existing mechanical precision fertilization and sowing structure, which includes a seed box, a fertilizer box, a precision seed metering device, a fertilizer metering device, a conveying pipe, and a disc-type furrow opener. The seed box and fertilizer box are fixed above the support frame 1 and are separated by partitions to store seeds and fertilizers. The precision seed metering device and fertilizer metering device are respectively installed at the discharge positions of the seed box and fertilizer box. The upper end of the conveying pipe is connected to the corresponding discharge position, and the lower end faces the furrow area opened by the disc-type furrow opener. The disc-type furrow opener is rotatably installed on the lower part of the support frame 1 and rolls into the soil to form a seed furrow when the machine moves.

[0050] The metering wheel of the precision seed meterer picks up seeds individually or quantitatively through the seed troughs, while the metering wheel of the fertilizer meterer quantitatively outputs fertilizer through changes in rotational volume. The metering wheels of both are rotated through a mechanical transmission structure that is linked to the walking speed commonly used in existing agricultural machinery. This mechanical transmission structure is composed of sprockets, chains, drive shafts, and changing gears according to existing technology. By adjusting the transmission ratio, the seed and fertilizer dispensing amounts correspond to the travel distance of the integrated machine. The above-mentioned internal structures of seed and fertilizer dispensing and their transmission components are all existing mature technologies and no additional reference numerals are added.

[0051] The soil covering and compaction mechanism 5 includes a cage-type compaction roller rotatably mounted on the support bracket 1 and located behind the disc-shaped furrow precision fertilization and sowing mechanism 4. The cage-type compaction roller is rotatably connected to the support bracket 1 through bearing seats and support arms at both ends. When the integrated machine moves, the cage-type compaction roller is driven to roll by ground friction. Its cage bars move the loose soil on both sides of the seed furrow to the furrow area and compact the backfill soil layer. The compaction depth can be set between the support arm and the support bracket 1 using the existing hole adjustment and bolt locking structure. The bearings, support arms and adjustment components of this soil covering and compaction structure are all implemented using existing technology and no additional reference numerals are added.

[0052] Before using this device, the support bracket 1 is connected to the rear of the tractor 12 via the three-point suspension structure. The shaft drive branch of the cutter shaft 22 and the gear transmission box and belt drive branch of the drive wheel 344 are connected to the power output end of the tractor 12 respectively. Seeds and fertilizers are added to the seed box and fertilizer box respectively. The height of the three-point suspension, the height of the walking support wheel 11, the soil penetration depth of the disc furrow opener, and the pressing position of the cage-type press roller are adjusted according to the field conditions so that each working component is at the predetermined working height.

[0053] When the tractor 12 starts to pull the integrated machine forward and outputs rotational power, the shaft drive structure drives the cutter shaft 22 to rotate. The cutter shaft 22 drives multiple rotary tillers 23 to continuously cut into the soil and cut, turn and initially break up the soil layer. During the rotary tillage process, the grass roots and tree roots that come into contact with the rotary tillers 23 come into contact with the anti-winding baffle 24 under the tendency of entanglement. The anti-winding baffle 24 blocks and guides the grass roots and tree roots, so that they are located between adjacent rotary tillers 23 that can be acted upon by the swing clearing rod 33.

[0054] At the same time, the gear transmission box and belt drive the drive wheel 344 to rotate continuously. The eccentric connection position on the drive wheel 344 pushes and pulls the reciprocating transmission seat 34 through the drive swing arm 343. Under the constraint of the linear guide structure, the reciprocating transmission seat 34 moves horizontally back and forth along the length direction of the working bracket 31. The transmission plate 341 moves synchronously with the reciprocating transmission seat 34 and drives the swing clearing rod 33 to swing back and forth around its hinge position with the swing arm support beam 32 through the transmission arm 342. The universal joints at both ends of the transmission arm 342 adapt to the angle changes at both ends during the movement, reducing the jamming of the linkage transmission.

[0055] During the swinging motion, the active end of the swinging clearing rod 33 is located between two adjacent rotary tillers 23 and passes through the clearance gap between adjacent anti-winding baffles 24. It periodically pulls the grass roots and tree roots guided by the anti-winding baffles 24. When the pulling force overcomes the entanglement and friction constraints between the entangled material and the rotary tiller 23, the grass roots and tree roots detach from the rotary tiller 23 and are released into the soil, thereby preventing the entangled material from continuously accumulating around the rotary tiller 23 and the blade shaft 22. The movement trajectory of the swinging clearing rod 33 is offset from the rotation trajectory of the rotary tiller 23, so it does not have a rigid collision with the rotary tiller 23 when the pulling action is completed.

[0056] When the reciprocating transmission seat 34 moves back and forth, it synchronously drives the soil loosening tooth mounting frame 35 and the soil loosening tooth 36 to move horizontally back and forth. The soil loosening tooth 36 passes through the clearance gap between adjacent anti-winding baffles 24 and is cut into and moved by the soil loosening tooth head 362 after rotary tillage. This causes the soil clods, fine roots and root-stem intertwined areas that are still accumulated after rotary tillage to be moved back and forth and loosened a second time. Since the movement trajectory of the soil loosening tooth 36 and the swing unblocking rod 33 are separated from each other and staggered from the rotation trajectory of the rotary tillage blade 23, the unblocking action and the soil loosening action can be carried out continuously while sharing the reciprocating transmission seat 34.

[0057] After rotary tillage and loosening, the soil moves forward with the integrated machine and enters the working area of ​​the disc-type precision fertilization and seeding mechanism 4 and the soil covering and compaction mechanism 5 in sequence. The disc ditcher rolls and cuts into the loose soil layer to form a ditch. The precision seed metering device and fertilizer metering device output seeds and fertilizers respectively according to the travel distance of the integrated machine. The seeds and fertilizers fall into the corresponding ditch area through the conveying pipe. Then, the cage-type compaction roller rolls on the ground and backfills the loose soil on both sides of the ditch into the ditch. At the same time, the backfill soil layer is compacted, completing the continuous operation cycle of rotary tillage, dynamic unblocking, loosening, ditching, precision fertilization, precision seeding, soil covering and compaction.

[0058] In summary, this invention, through the guidance of the anti-entanglement baffle 24, the periodic pulling of the swing unblocking rod 33, and the synchronous reciprocating unblocking of the soil by the soil-dredging teeth 36, completes the separation of entangled materials and subsequent soil layer preparation during the continuous rotation of the rotary tiller 23. The subsequent composite operation is completed through the disc-shaped ditching precision fertilization and sowing mechanism 4 and the soil covering and compaction mechanism 5, thus forming a complete working principle in which power transmission, motion conversion, unblocking execution, soil unblocking execution, and seed, fertilizer, and soil covering operations are interconnected.
