Description

Technical Field

[0001] This invention relates to the field of seeding machinery technology. Background Technology

[0002] In recent years, with the development of agricultural modernization, advanced and suitable agricultural machinery has played a vital role in agricultural production. Seeders are widely used in agricultural production, providing a solid guarantee for sustainable agricultural development and modernization. With the implementation of advanced agricultural technologies, the requirements for agricultural machinery in agricultural production are becoming increasingly stringent. In addition to sowing, seeders often work in conjunction with rotary tillers and other agricultural machinery, simultaneously performing multiple functions such as hooking, mulching, laying water-saving pipes, fertilizing, and covering with soil. This increased functionality has led to a longer overall structure for seeders. Seeders require tractor towing during operation; during transportation and field operations, an excessively long structure results in a large turning radius, affecting operational efficiency, hindering sowing operations, and increasing safety hazards during transportation and operation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a combined tillage machine that is easy to operate and has high working efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A combined tillage machine includes a suspended frame, with rotary tillers in front of the suspended frame for rotary tilling to loosen the soil, and at least one set of ridging, mulching and sowing devices behind the rotary tillers.

[0006] The ridging and film-laying sowing device includes ridging devices arranged in sequence from front to back, a pair of ridge wall scraping and shaping discs, film installation rollers, a pair of front covering discs, a sower, and a pair of rear covering discs.

[0007] The ridging device includes a pair of symmetrically arranged plate-shaped ridging structures and a ridge-top smoothing plate. The plate-shaped ridging structures are connected from front to back to a furrowing plate, a furrow widening plate, and a ridge-wall smoothing plate. The furrowing plate is inclined outward at an angle of less than 30° relative to the left and right symmetry line to reduce the forward resistance in the cultivated land. The furrow widening plate is inclined outward at a larger angle relative to the furrowing plate. The ridge-wall smoothing plate has an inclined surface adapted to the ridge wall. The pair of furrow widening plates gather the inner cultivated soil opened by the furrowing plate into the space between the pair of ridge-wall smoothing plates to form a ridge. The furrow widening plate makes the gathered cultivated soil form the ridge wall. The ridge-top smoothing plate is horizontally fixed at the upper end of the pair of ridge-wall smoothing plates to smooth the top of the ridge.

[0008] A pair of ridge wall scraping and shaping discs are symmetrically arranged on the left and right, and their installation positions correspond to the two side walls of the ridge created by the ridging device. Each ridge wall scraping and shaping disc is fixed to the frame through its own ridge wall scraping and shaping disc bracket and is rotatably connected to the ridge wall scraping and shaping disc bracket. The pair of ridge wall scraping and shaping discs are tilted outward from front to back to scrape and shape the two side walls of the ridge created by the ridging device, so that the scraped loose soil falls into the furrows on both sides of the ridge.

[0009] The mulch film installation roller is adapted to the mulch film core hole and is used to insert into the core hole of the whole roll of mulch film to load the mulch film. Its installation position can cover the mulch film on the ridge.

[0010] The seeding nozzle of the seeder corresponds to the middle of the ridge created by the ridging device, so that the seeds are sown in the middle of the ridge;

[0011] A pair of front covering discs are located in front of the seeder, and a pair of rear covering discs are located behind the seeder. Each front covering disc is fixed to the frame by its own front covering disc bracket and is rotatably connected to the front covering disc bracket. Each rear covering disc is fixed to the frame by its own rear covering disc bracket and is rotatably connected to the rear covering disc bracket. The installation positions of the pair of front covering discs and the pair of rear covering discs correspond to the positions of the furrows on both sides of the ridge, and they are inclined inward from front to back, so that during the movement, the loose soil scraped into the furrows by the pair of ridge wall scraping and shaping discs is filled onto the mulch film.

[0012] The suspended frame is a foldable frame, which includes a front frame, a rear frame, and a piston actuator. The front frame and the rear frame are hinged together, and a piston actuator is provided between the front frame and the rear frame for folding, raising, and lowering the rear frame. Rotary tillers, ridging devices, ridge wall scraping and shaping discs, and mulch film installation rollers are installed on the front frame, while seeders, a pair of front covering discs, and a pair of rear covering discs are installed on the rear frame.

[0013] The invention is further improved in that:

[0014] A film compaction and cutting device is provided between the film installation roller and the seeder. The film compaction and cutting device includes a film pressing and cutting linkage mechanism, a film compaction roller and a film cutting claw.

[0015] The plastic film pressing and cutting linkage mechanism is a symmetrical structure, which includes a crossbeam, a left linkage structure and a right linkage structure;

[0016] The middle part of the crossbeam is fixedly connected to the front frame;

[0017] The left-side linkage structure and the right-side linkage structure are identical in structure, including a longitudinal beam, a follower connecting rod for the mulch film compaction roller, a driven connecting rod for the mulch film cutting claw, and a control connecting rod for the cutting claw.

[0018] The upper end of the follower connecting rod of the plastic film compaction roller is rotatably connected to the front end of the longitudinal beam, and the upper end of the follower connecting rod of the plastic film cutting claw is rotatably connected to the rear end of the longitudinal beam.

[0019] The cutting claw control linkage includes a control rod and a cutting claw connecting rod. The upper end of the control rod is hinged to the upper end of the cutting claw connecting rod. The control rod is rotatably connected to the follower connecting rod of the mulch film compaction roller and the driven connecting rod of the mulch film cutting claw through a rotating shaft.

[0020] The lower end of the follower connecting rod of the mulch compaction roller in the left linkage structure is rotatably connected to the left end of the mulch compaction roller; the lower end of the follower connecting rod of the mulch compaction roller in the right linkage structure is rotatably connected to the right end of the mulch compaction roller; the lower end of the driven connecting rod of the mulch cutting claw in the left linkage structure is rotatably connected to the upper left end of the mulch cutting claw; the lower end of the driven connecting rod of the mulch cutting claw in the right linkage structure is rotatably connected to the upper right end of the mulch cutting claw; the lower end of the cutting claw connecting rod in the left linkage structure is rotatably connected to the lower left end of the mulch cutting claw; and the lower end of the cutting claw connecting rod in the right linkage structure is rotatably connected to the lower right end of the mulch cutting claw.

[0021] When sowing is being carried out, the hydraulic suspension system of the suspended frame controls the front frame to fall to the working position. Under its own weight, the mulch film compaction roller falls to compact the mulch film laid on the ridge. The angle between the longitudinal beam and the mulch film compaction roller and the follower connecting rod becomes relatively smaller, which causes the control rod to move the mulch film cutting claw upward from the follower connecting rod. The cutting claw connecting rod then drives the mulch film cutting claw to lift backward, so that the mulch film cutting claw moves upward away from the mulch film.

[0022] After the sowing operation is completed, the hydraulic suspension system of the suspended frame controls the front frame to rise. Under its own weight, the mulch film compaction roller falls freely. The angle between the longitudinal beam and the mulch film compaction roller follower connecting rod increases, thereby causing the control rod to drive the mulch film cutting claw to descend along the follower connecting rod. The cutting claw connecting rod drives the mulch film cutting claw to fall forward, so that the mulch film cutting claw moves downward to cut the mulch film.

[0023] The mulch film compaction and cutting device is also equipped with a pair of mulch film furrow compaction wheels. The pair of mulch film furrow compaction wheels are rotatably connected to the left end and the right end of the crossbeam respectively through compaction wheel brackets. The installation positions of the pair of mulch film furrow compaction wheels 20 correspond to the furrow positions on both sides of the ridge created by the ridging device, so that the mulch film laid in the furrow is compacted under its own weight.

[0024] A drip irrigation tape axle disc is provided at the upper end of the front frame, which is used to insert the core hole of the whole roll of drip irrigation tape to load the mulch film and transport the drip irrigation tape along the furrow.

[0025] The combined tillage machine is equipped with two sets of ridging, film-laying and sowing devices.

[0026] The seeder is a duckbill type seeder.

[0027] The beneficial effects of adopting the above technical solution are as follows:

[0028] The suspended frame features a foldable design. When the piston-driven actuator folds up the rear frame, the combine tiller is in a flexible and maneuverable state. This shortens the overall structure of the combine tiller, reduces the turning radius, and facilitates towing and transporting the combine tiller before and after sowing operations, as well as adjusting the sowing position before sowing. When the piston-driven actuator folds down the rear frame, the combine tiller is in sowing mode for sowing operations. It features ease of operation and high work efficiency.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0040] Depend on Figures 1-8 As can be seen from the embodiment shown, this embodiment includes a suspended frame 1, a rotary tiller 2 is provided in front of the suspended frame 1 for rotary tilling to loosen the soil, and at least one set of ridging, film laying and sowing device is provided behind the rotary tiller 2.

[0041] The ridging and film-laying sowing device includes ridging devices arranged in sequence from front to back, a pair of ridge wall scraping and shaping discs 3, film installation rollers 4, a pair of front covering discs (6), a sower 5, and a pair of rear covering discs (11).

[0042] The ridging device includes a pair of symmetrically arranged plate-shaped ridging structures and a ridge top smoothing plate 7. The plate-shaped ridging structures are connected from front to back to a furrowing plate 8, a furrow widening plate 9, and a ridge wall smoothing plate 10. The furrowing plate 8 is inclined outward at an angle of less than 30° relative to the left and right symmetry line to reduce the forward resistance in the cultivated land. The furrow widening plate 9 is inclined outward at a larger angle relative to the furrowing plate 8. The ridge wall smoothing plate 10 has an inclined surface adapted to the ridge wall. The pair of furrow widening plates 9 gather the inner cultivated soil opened by the furrowing plate 8 into the space between the pair of ridge wall smoothing plates 10 to form a ridge. The furrow widening plates 9 make the gathered cultivated soil form the ridge wall. The ridge top smoothing plate 7 is horizontally fixed at the upper end of the pair of ridge wall smoothing plates 10 to smooth the top of the ridge.

[0043] A pair of ridge wall scraping and shaping discs 3 are symmetrically arranged on the left and right, and their installation positions correspond to the two side walls of the ridge created by the ridging device. Each ridge wall scraping and shaping disc 3 is fixed to the frame 1 through its own ridge wall scraping and shaping disc bracket and is rotatably connected to the ridge wall scraping and shaping disc bracket. The pair of ridge wall scraping and shaping discs 3 are tilted outward from front to back to scrape and shape the two side walls of the ridge created by the ridging device, so that the scraped loose soil falls into the furrows on both sides of the ridge.

[0044] The mulch film installation roller 4 is adapted to the mulch film core hole and is used to insert into the core hole of the whole roll of mulch film to load the mulch film. Its installation position can cover the mulch film on the ridge.

[0045] The seeding port of the seeder 5 corresponds to the middle of the ridge created by the ridging device, so as to sow the seeds to the middle of the ridge;

[0046] A pair of front covering discs 6 are located in front of the seeder 5, and a pair of rear covering discs 11 are located behind the seeder 5. Each front covering disc 6 is fixed to the frame 1 by its own front covering disc bracket and is rotatably connected to the front covering disc bracket. Each rear covering disc 11 is fixed to the frame 1 by its own rear covering disc bracket and is rotatably connected to the rear covering disc bracket. The installation positions of the pair of front covering discs 6 and the pair of rear covering discs 11 correspond to the positions of the furrows on both sides of the ridge, and are inclined inward from front to back, so that during the movement, the loose soil scraped into the furrows by the pair of ridge wall scraping and shaping discs 3 is filled onto the mulch film, thereby fixing the mulch film on the ridge.

[0047] The suspended frame 1 is a foldable frame, comprising a front frame 1-1, a rear frame 1-2, and a piston actuator 1-3. The front frame 1-1 and the rear frame 1-2 are hinged together. The piston actuator 1-3 is located between the front frame 1-1 and the rear frame 1-2 for folding, raising, and lowering the rear frame 1-2. The rotary tiller 2, ridging device, ridge wall scraping and shaping disc 3, and mulch film installation roller 4 are mounted on the front frame 1-1. The seeder 5 and a pair of front covering discs are also included. 6 and a pair of rear soil covering discs 11 are installed on the rear frame 1-2. When the piston actuator 1-3 controls the rear frame 1-2 to fold and lift, the combined tiller is in a flexible and maneuverable state, which can shorten the overall structure of the combined tiller, reduce the turning radius, and facilitate the dragging and transportation of the combined tiller before and after sowing operations, as well as the adjustment of the sowing position before sowing operations. When the piston actuator 1-3 controls the rear frame 1-2 to fold and fall, the combined tiller is in the sowing operation state to carry out sowing operations.

[0048] A film compaction and cutting device is provided between the film installation roller 4 and the seeder 5. The film compaction and cutting device includes a film pressing and cutting linkage mechanism, a film compaction roller 12 and a film cutting claw 13.

[0049] The plastic film pressing and cutting linkage mechanism is a symmetrical structure, which includes a crossbeam 14, a left linkage structure and a right linkage structure;

[0050] The middle part of the crossbeam 14 is fixedly connected to the front frame 1-1;

[0051] The left-side linkage structure and the right-side linkage structure are identical, including a longitudinal beam 15, a follower connecting rod 16 for the mulch film compaction roller, a driven connecting rod 17 for the mulch film cutting claw, and a cutting claw control connecting rod.

[0052] The upper end of the follower connecting rod 16 of the mulch film compaction roller is rotatably connected to the front end of the longitudinal beam 15, and the upper end of the follower connecting rod 17 of the mulch film cutting claw is rotatably connected to the rear end of the longitudinal beam 15.

[0053] The cutting claw control linkage includes a control rod 18 and a cutting claw connecting rod 19. The upper end of the control rod 18 is hinged to the upper end of the cutting claw connecting rod 19. The control rod 18 is rotatably connected to the follower connecting rod 16 of the mulch film compaction roller and the driven connecting rod 17 of the mulch film cutting claw through a rotating shaft.

[0054] The lower end of the follower connecting rod 16 of the left-side linkage structure is rotatably connected to the left end of the mulch compaction roller 12; the lower end of the follower connecting rod 16 of the right-side linkage structure is rotatably connected to the right end of the mulch compaction roller 12; the lower end of the driven connecting rod 17 of the left-side linkage structure is rotatably connected to the upper left end of the mulch cutting claw 13; the lower end of the driven connecting rod 17 of the right-side linkage structure is rotatably connected to the upper right end of the mulch cutting claw 13; the lower end of the cutting claw connecting rod 19 of the left-side linkage structure is rotatably connected to the lower left end of the mulch cutting claw 13; and the lower end of the cutting claw connecting rod 19 of the right-side linkage structure is rotatably connected to the lower right end of the mulch cutting claw 13.

[0055] When sowing is being carried out, the hydraulic suspension system of the suspended frame 1 controls the front frame 1-1 to fall to the working position. Under its own weight, the mulch film compaction roller 12 falls down to compact the mulch film laid on the ridge. The angle between the longitudinal beam 15 and the mulch film compaction roller follower connecting rod 16 becomes smaller, thereby causing the control rod 18 to drive the mulch film cutting claw to move upward on the follower connecting rod 17. The cutting claw connecting rod 19 drives the mulch film cutting claw 13 to lift backward, so that the mulch film cutting claw 13 moves upward away from the mulch film.

[0056] After the sowing operation is completed, the hydraulic suspension system of the suspended frame 1 controls the front frame 1-1 to rise. Under its own gravity, the mulch film compaction roller 12 falls freely. The angle between the longitudinal beam 15 and the mulch film compaction roller follower connecting rod 16 becomes larger, thereby causing the control rod 18 to drive the mulch film cutting claw to descend along the follower connecting rod 17. The cutting claw connecting rod 19 drives the mulch film cutting claw 13 to fall forward, so that the mulch film cutting claw 13 moves downward to cut the mulch film.

[0057] The mulch film compaction and cutting device is also equipped with a pair of mulch film furrow compaction wheels 20. The pair of mulch film furrow compaction wheels 20 are rotatably connected to the left end and the right end of the crossbeam 14 respectively through compaction wheel brackets 21. The installation positions of the pair of mulch film furrow compaction wheels 20 correspond to the furrow positions on both sides of the ridge created by the ridging device, so that the mulch film laid in the furrow is compacted under its own weight.

[0058] A drip irrigation tape axle disc 22 is provided at the upper end of the front frame 1-1, which is used to insert the core hole of the whole roll of drip irrigation tape to load the mulch film and transport the drip irrigation tape along the furrow.

[0059] The combined tillage machine is equipped with two sets of ridging, film-laying and sowing devices.
