Description

[Technical Field]

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a film-covered, synchronous hole-seeding, hole-irrigated, and dry-drained direct seeding machine for rice paddies. [Background technology]

[0002] Due to climate change and the continuous increase in industrial and urban water consumption, the contradiction between the already limited water resources and agricultural water use is becoming increasingly serious, and drought-tolerant, water-saving, green, high-yield, and high-efficiency cultivation methods have become the trend in modern agricultural development. Direct seeding of rice with film-covered, synchronous hole sowing and hole irrigation is a drought-tolerant, water-saving, fertilizer-reducing, green, high-yield, and highly efficient cultivation mode, and is of great significance to the development of the rice industry and food security in drought- and arid regions.

[0003] A duckbill seeder is a planting machine used to sow agricultural seeds, and is characterized by uniform sowing, consistent depth, stable row spacing, and seed conservation. When sowing seeds on top of a film, conventional duckbill seeders have rollers made of hard plastic, which means that the smooth outer walls of the rollers come into contact with the film during sowing, easily causing slippage during the rolling process and resulting in misalignment between the film holes and the seed holes, which seriously affects seed germination and seedling establishment. Watering is difficult during the film-stretching and hole-drilling dry-field direct sowing process, and large amounts of weeds grow in the soil-removal trenches between the films, preventing the rapid supply of water and fertilizer. This results in low germination and seedling establishment rates, poor growth conditions, and low yields.

[0004] To this end, the present invention provides a duckbill-type film-covered non-slip stationary seeding device and a dry-field rice direct seeding machine using the same. Summary of the Invention [Problem to be solved by the invention]

[0028] The present invention has multiple functions, improving the stability, precision, and adaptability of the machine, improving the seeding quality of film-covered, dry-seeded rice, and truly realizing film-covered, dry-seeded rice cultivation. It solves the problem of difficulty in irrigating the film-covered, hole-punched, dry-seeded rice, enabling water to be poured into the holes simultaneously with sowing, significantly improving the seedling establishment rate of film-covered, hole-punched, dry-seeded rice, and producing uniform, complete, and strong seedlings.

[0029] As a more preferred solution, the rotary tillage device 2 includes a transmission shaft 2001 rotatably connected to the frame 1, a plurality of rotary tillage blades 2002 fixedly connected to the transmission shaft 2001, a transmission device 2003 fixedly connected to the top end of the frame 1, the transmission device 2003 and the transmission shaft 2001 interlocking, and a soil splitter 2004 located between the plurality of rotary tillage blades 2002 fixedly connected to the bottom end of the transmission device 2003.

[0030] The transmission device 2003 rotates the transmission shaft 2001, which causes the rotary tillage blade 2002 to rotate and tillage is achieved.

[0031] In a more preferred solution, a plurality of depth limiting assemblies 10 are mounted at equal intervals on the front end of the frame 1, and each depth limiting assembly 10 includes a sleeve 1001 fixedly connected to the front end of the frame 1 so as to extend along the vertical direction, a slidable threaded sleeve 1002 connected to the bottom end of the sleeve 1001, a threaded rod 1003 threadedly engaged in the threaded sleeve 1002, a top plate fixedly connected to the top end of the sleeve 1001, the threaded rod 1003 penetrating the top plate and rotatably connected to the top plate, and the bottom of the threaded sleeve 1002 extends from the sleeve 1001 and has a depth limiting wheel 1004 attached thereto. The working depth of the device is controlled by controlling the relative distance between the sliding sleeve and the threaded sleeve 1002 with the threaded rod 1003.

[0039] While rotary tilling the soil, the rotary tilling blade 2002 simultaneously dumps some of the soil into the covering box 6001, causing it to flow out from the bottom of the covering box 6001 and pushing it onto the top surface of the film to form a soil furrow. In this way, the mechanical structure of the front removing film pushing machine is simplified, the secondary soil tilling process is reduced, the stability of the machine is improved, the manufacturing cost of the machine is reduced, and the problem of large amounts of weeds growing in the removing furrows due to side removing soil is avoided.

[0041] Two seeding wheels 8005 are assembled into a set to form a single unit seeder, with narrow spacing between the two seeding wheels in each set and wide spacing between the sets. Wide-narrow spacing seeding is used, with the top of the wide-spacing film serving as a soil pressing strip and the bottom of the narrow-spacing film serving as a water and fertilizer groove, allowing for the simultaneous supply of fertilizer and water. It also has the function of collecting rainwater and allowing it to enter the holes, thereby realizing water-saving, fertilizer-reducing, and drought-resistant cultivation.

[0042] The angle adjustment assembly includes a stop rod fixedly connected to the sowing duckbill 8006, and a torsion spring is attached between the stop rod and the sowing wheel 8005 to ensure that the sowing duckbill has stable recovery ability. A rotatable adjustment wheel is connected to one side of the sowing wheel 8005, and multiple push rods are fixedly connected to the adjustment wheel at equal intervals, with the axes of the push rods parallel to the axis of the sowing wheel 8005. The push rods abut against the stop rods, and the push rods press the stop rods to cause a corresponding angle change, thereby adjusting the angle of the sowing duckbill 8006. The size and shape of the film holes can be adjusted by changing the opening degree of the sowing duckbill 8006.

[0043] The outer wall of the seeding wheel 8005 is covered with an anti-slip mat including a foam rubber mat 8007, and the foam rubber mat 8007 has escape grooves formed thereon corresponding to the seeding duckbills 8006, respectively.

[0044] The foam rubber mat 8007 is made of EPDM (ethylene propylene diene rubber) foam rubber tape with a hardness of 25 degrees, a width of 8 cm, a thickness of 1.5 cm, a recessed groove length of 5 cm and a width of 3 cm. Holes are cut by a press, and a strong adhesive is attached to one side of the foam rubber tape, which can be attached around the seeding wheel 8005 to form an elastic anti-slip ring layer.

A plurality of guide grooves 8009 are formed at equal intervals in the circumferential direction on the sowing wheel 8005, and both ends of the guide groove 8009 are corresponding to the seed drop guide disc 8008 and the sowing duckbill 8006, respectively. A transmission assembly is attached to the other side of the sowing wheel 8005, and the irrigation device 9 and the sowing wheel 8005 are linked by the transmission assembly.

[0046] As a more preferred solution, the irrigation device 9 includes fixed plates 9001 symmetrically connected to both ends of a mounting shaft in a rotatable manner, a rotatable steel water supply pipe 9002 is connected between the two fixed plates 9001, a water tank is fixedly connected to the top end of the support frame 3001, the water tank and the steel water supply pipe 9002 are fixedly connected by a hose, a plurality of water wheels 9003 are fixedly connected to the steel water supply pipe 9002 at equal intervals, and the plurality of water wheels 9003 and the plurality of seeding wheels 8005 are respectively The water turbine 9003 has a hollow structure, a plurality of through holes are formed in the water supply steel pipe 9002, the plurality of through holes are arranged corresponding to a plurality of water turbines 9003, and the plurality of through holes are connected to the cavity of the water turbine 9003, a plurality of water supply holes 9004 are formed in the outer wall of the water turbine 9003, a plurality of scraper plates 9005 are fixedly connected between the two fixed plates 9001, and the plurality of scraper plates 9005 are arranged corresponding to a plurality of water turbines 9003, respectively.

[0047] The circumference of the water wheel 9003 must be an integer multiple of the arc length between adjacent sowing duckbills 8006, and the arc length between two adjacent drainage holes in the water wheel 9003 is equal to the arc length between two adjacent duckbills. By attaching a water supply valve to the hose, the amount of water injected can be adjusted by the water supply valve.

[0048] The sowing wheel 8005 has a diameter of 50 cm, 10 duckbills, and a hole spacing of 15.7 cm, and the water wheel 9003 has a diameter of 20 cm and four water injection holes, the diameter of which is 2 cm.

[0051] In this way, the problem of misalignment between the film holes and the seed holes in direct seeding of dry paddy fields with film covering and perforations is effectively solved. By pushing the soil before sowing, improving the sowing wheel 8005, and pressing with the water wheel 9003, the stability of the film position is guaranteed, the film holes and seed holes overlap, and the seeds can germinate from the film holes and establish seedlings.
