Description

Technical Field

[0001] The present invention relates to the technical field of seed drills, and in particular to a cotton seed drill in a melon-cotton intercropping mode. Background Art

[0002] Intercropping melons and cotton fully utilizes spatial niches. By rationally combining the planting of watermelons and cotton, it maximizes the utilization of light energy, space, and time resources. It also helps suppress the occurrence of pests, diseases, and weeds, mitigate natural disasters, and improve crop yield and quality. When intercropping melons and cotton, seeders typically use an integrated film covering and hole sowing process. However, after film covering, soil is simply scraped up to cover both sides of the film, which is not conducive to compacting the film and makes it easily blown away by strong winds. There are also methods that use a covering roller to cover the film again, but soil adhesion and clogging inside the covering roller prevents the soil from falling onto the film. Furthermore, during the subsequent hole sowing process, seeds can easily stick together and clump, preventing them from falling properly, resulting in empty seed sowing. Therefore, we have introduced a cotton seeder for melon-cotton intercropping. Summary of the Invention

[0019] A positioning ring is screwed on the outer side of the soil covering drum, and the positioning ring is located on the inner side of the corresponding limiting ring seat.

[0020] Preferably, the self-propelled seeding drum assembly includes an L-shaped frame distributed at equal intervals at the rear end of the frame, a seed temporary storage bucket fixed at the rear end of the horizontal portion of the L-shaped frame, an extension plate movably connected to the bottom of the vertical portion of the L-shaped frame by a pin, sealing heads fixed on both sides of the inner wall of the U-shaped bracket at the rear end of the extension plate, and a seeding drum sleeved between the sealing heads;

[0021] Both sides of the bottom of the seed temporary storage bucket are connected to the sealing head by using corrugated elbows, and the sowing drum is connected with the seed temporary storage bucket through the corrugated elbow.

[0022] Preferably, a horizontal plate is fixed on the upper side of the vertical portion of the L-shaped frame, and a tensioning spring is connected between the horizontal plate and the extension plate.

Under the rolling of the covering roller, the soil in the covering roller is laid on the film at intervals, which can simultaneously achieve the film covering and the film compaction, improve the sowing efficiency and ensure that the soil will not be blown away by the strong wind after the film is compacted; when the covering roller rolls, the driving component also drives the stirring in the middle of the covering roller. The component rotates, and the covering drum and the stirring component rotate in opposite directions, which can improve the stirring and crushing of the soil in the covering drum to prevent the soil from being blocked in the covering drum. At the same time, the self-propelled sowing drum component at the rear end of the frame punctures the film and sows the seeds in the soil. As the sowing drum rotates, the inner wall of the sowing drum drives the seeds to move upward, and after moving up a distance, the seeds fall again under the action of their own gravity, thereby stirring the seeds, and the stripping plate can also stir the seeds at this time to prevent the seeds from sticking together and causing the seeds to be unable to leak out through the sowing drum.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example:

[0042] See also Figure 1-12 , the present invention provides a technical solution:

[0043] A cotton seeder in a melon-cotton intercropping mode comprises a frame 1. A connecting frame 2 for mounting with a traction tractor is provided at the middle of the front end of the frame 1. The traction tractor is a Tianjin Tieniu 654 or 724 tractor, a Xinjiang 704 tractor, an 804 rotary tiller matching tractor, or other models that meet usage requirements.

[0044] like Figure 1 and 2 As shown, when the towing tractor moves forward (to the left in the figure), the towing tractor drives the frame 1 to move forward through the connecting frame 2.

[0045] A film rewinding roller 3 is provided at the upper front end of the frame 1, and mounting seats 16 for mounting the film rewinding roller 3 are provided on both sides of the upper front end of the frame 1. A clamp is provided on the top of the mounting seat 16, which is used to limit the roller shafts at both ends of the film rewinding roller 3 and to install them. When the guide wheel 13 pulls the film on the film rewinding roller 3 downward, the film rewinding roller 3 itself can rotate, thereby ensuring that the film can be pulled off the film rewinding roller 3.

[0046] The middle part of the lower end of the frame 1 is provided with support wheels 4 and guide wheels 13 driven between two sets of support wheels 4;

[0047] Vertical plates 18 for mounting support wheels 4 are provided on both sides of the middle portion of the lower end of the frame 1, and a rotating rod 17 connected to the middle portion of the support wheel 4 passes through the vertical plates 18, and the guide wheels 13 are evenly spaced on the rotating rod 17;

[0048] When the frame 1 moves forward, the support wheel 4 rotates counterclockwise and drives the guide wheel 13 to rotate counterclockwise through the rotating rod 17, so that the guide wheel 13 pulls the film on the film retracting roller 3 downward, and when the soil covers both sides of the film, the film is spread flat on the ground soil.

[0049] A middle connecting tube 20 is installed in the center of the rear lower end of the frame 1 , and the top of the middle connecting tube 20 is connected and fixed to the rear inner wall of the frame 1 by a fixing frame 21 .

[0050] The covering roller 14 is movably connected to both ends of the middle connecting tube 20. An annular groove 29 is provided at both ends of the middle connecting tube 20. The inner end of the covering roller 14 is inserted into the annular groove 29. In this way, when the covering roller 14 rolls automatically, the inner end of the covering roller 14 can rotate in the annular groove 29.

[0051] And U-shaped frames 22 are symmetrically fixed to the outer sides of both ends of the middle connecting cylinder 20, and the outer ends of the two sets of U-shaped frames 22 are connected to the limiting ring seat 19, which is sleeved on the outer end of the covering drum 14. A positioning ring 43 is screwed on the outer side of the covering drum 14, and the positioning ring 43 is located on the inner side of the corresponding limiting ring seat 19; in this way, the setting of the limiting ring seat 19 plays a supporting role on the outer end of the covering drum 14, so as to ensure that the covering drum 14 rotates smoothly and stably.

[0052] The inner wall of the U-shaped frame 22 is provided with a cleaning rod 34, which is in close contact with the outer wall of the covering drum 14. With this arrangement, when the covering drum 14 rolls, the outer wall of the covering drum 14 can be cleaned by the cleaning rod 34, and the soil attached to the outer wall of the covering drum 14 can be removed to ensure that the outer wall surface of the covering drum 14 is clean, and to prevent the outer wall surface of the covering drum 14 from being attached to a large amount of soil, which causes the covering drum 14 to roll unsmoothly.

[0053] The outer end surface of the covering roller 14 is evenly spaced with walking plates 6, so that when the frame 1 moves forward, the walking plates 6 come into contact with the ground, thereby causing the walking plates 6 to drive the covering roller 14 to rotate counterclockwise, thereby realizing automatic rolling of the covering roller 14.

[0054] Furthermore, the frame 1 is provided with an inclined scraper wheel 5 on both sides of the rear portion thereof, located outside the outer end of the covering roller 14. A mounting bracket 12 is provided at the upper rear end of the frame 1. The inclined scraper wheel 5 is movably connected to the inner side of the bottom of a connecting plate 15, and the connecting plate 15 is fixed with bolts after passing through the mounting bracket 12. This arrangement allows the height of the inclined scraper wheel 5 to be adjusted by adjusting the height of the connecting plate 15. When the inclined scraper wheel 5 moves forward with the frame, the inclined scraper wheel 5 can scrape up the ground soil, covering part of the soil on both sides of the film, while the other part of the soil enters the outer end of the covering roller 14.

[0055] The inner wall of the covering drum 14 is evenly spaced with pusher plates 33. As the covering drum 14 rolls, the pusher plates 33 are used to push soil that has just entered the covering drum 14 into the interior of the covering drum 14. Soil leakage grooves 42 are evenly spaced at both ends of the surface of the covering drum 14. This allows soil that enters through the outer end of the covering drum 14 to enter the interior of the covering drum 14. As the covering drum 14 rotates, the soil inside the covering drum 14 falls through the leakage grooves 42 at its bottom onto the film, thereby further covering the film.

[0056] When the soil covering drum 14 rolls, the soil paddle 33 can also stir the soil inside the soil covering drum 14 to prevent the soil from adhering to the inner wall of the soil covering drum 14 and causing blockage;

[0057] Moreover, when the tractor moves forward at a constant speed, the covering drum 14 rolls at a constant speed, so that the soil inside the covering drum 14 can periodically fall onto the film through the soil leakage groove 42 that rotates to the bottom of the covering drum 14, so that the soil can fall on the film at equal intervals, which can prevent the film from being blown away by strong winds.

[0058] When the tractor pulls the frame 1 forward, the support wheel 4 pulls the film from the film retracting roller 3 through the guide wheel 13 and spreads it flat on the ground. The oblique scraper wheel 5 covers the ground soil on both sides of the film and also moves part of the ground soil into the covering roller 14. As the covering roller 14 rolls, the soil in the covering roller 14 is laid on the film at intervals.

[0059] When the soil covering drum 14 rolls, the driving assembly also drives the stirring assembly in the middle of the soil covering drum 14 to rotate, and the soil covering drum 14 and the stirring assembly rotate in opposite directions to prevent the soil from being blocked in the soil covering drum 14;

[0060] The drive assembly includes an outer gear ring 39 fixed to the outside of the inner end of the covering roller 14, a gear 41 meshing with the top of the outer gear ring 39, a first pulley 36 fixed between the two sets of gears 41 via a rotating shaft 37, and a second pulley 40 centrally located inside the middle connecting cylinder 20;

[0061] A raised plate 35 is provided on both sides of the top of the middle connecting cylinder 20. A rotating shaft 37 passes through the raised plate 35. An open groove 38 is provided on the top of the middle connecting cylinder 20. The belt 50 on the first pulley 36 extends through the open groove 38 into the middle connecting cylinder 20 and is connected to the second pulley 40.

[0062] The stirring assembly includes a long rod 31 that passes through the second pulley 40 and extends into the interior of the covering roller 14, and a stirring rod 32 arranged on the surface of the long rod 31. Sealing disks 30 are provided at both ends of the middle connecting tube 20, and the sealing disks 30 are sleeved on the outside of the long rod 31.

[0063] When the covering drum 14 rolls counterclockwise, the outer gear ring 39 at the inner end of the covering drum 14 also rotates counterclockwise, and the outer gear ring 39 drives the rotating shaft 37 and the first pulley 36 on the rotating shaft 37 to rotate clockwise through the gear 41, so that the first pulley 36 drives the second pulley 40 and the long rod 31 to rotate clockwise through the belt 50, so that the stirring rod 32 on the long rod 31 can stir and crush the soil inside the covering drum 14 to prevent the soil from adhering to the inner wall of the covering drum 14;

[0064] Since the diameter of the outer gear ring 39 is larger than the diameter of the gear 41, the long rod 31 can drive the stirring rod 32 thereon to rotate at a high speed, thereby improving the stirring and crushing effect of the soil inside the soil covering drum 14;

[0065] Since the covering roller 14 rolls counterclockwise and the long rod 31 rotates clockwise, the covering roller 14 and the long rod 31 of the stirring assembly rotate in opposite directions, which can further improve the stirring and crushing effect of the stirring rod 32 on the soil inside the covering roller 14 to prevent the soil from adhering to the inner wall of the covering roller 14 and causing blockage.

[0066] At the same time, the self-propelled sowing drum assembly at the rear end of the frame 1 punctures the film and sows the seeds in the soil;

[0067] The self-propelled seeding drum assembly includes L-shaped frames 11 distributed at equal intervals at the rear end of a frame 1, a seed temporary storage bucket 10 fixed to the rear end of the horizontal portion of the L-shaped frame 11, an extension plate 8 movably connected to the bottom of the vertical portion of the L-shaped frame 11 by a pin 23, sealing heads fixed on both sides of the inner wall of a U-shaped bracket 25 at the rear end of the extension plate 8, and a seeding drum 27 sleeved between the sealing heads;

[0068] Both sides of the bottom of the seed temporary storage bucket 10 are connected to the sealing head by using corrugated elbows 9, and the sowing drum 27 is connected to the seed temporary storage bucket 10 through the corrugated elbows 9.

[0069] In the specific melon-cotton intercropping mode, melon and fruit (watermelon, etc.) seeds are put into the seed temporary storage bucket 10 in the middle position, and cotton seeds are put into the seed temporary storage bucket 10 on both sides.

[0070] A horizontal plate 26 is fixed on the upper side of the vertical part of the L-shaped frame 11, and a tensioning spring 24 is connected between the horizontal plate 26 and the extension plate 8. Such an arrangement allows the sowing roller 27 on the U-shaped bracket 25 to be in close contact with the film on the ground under the elastic force of the tensioning spring 24, so that when moving forward, the sowing drum 28 on the sowing roller 27 punctures the film and generates friction when in contact with the ground, thereby driving the sowing roller 27 to rotate.

[0071] The sealing head includes a sealing disk 7 fixed on both sides of the inner wall of the U-shaped bracket 25, a limiting support ring 44 fixed to the inner end of the sealing disk 7, two sets of reinforcing plates 45 symmetrically connected between the inner walls of the limiting support ring 44, a material-diverting plate 47 provided on the inner walls of the reinforcing plates 45, and an intermediate ring 46 fixed in the middle between the two sets of reinforcing plates 45. The bottom of the intermediate ring 46 is provided with a material leakage notch 48;

[0072] Both ends of the sowing drum 27 are sleeved on the outside of the limiting support ring 44 , and sowing drums 28 are evenly spaced in the middle of the outer side of the sowing drum 27 , and the sowing drums 28 are connected to the leakage holes 49 on the inner wall of the sowing drum 27 .

[0073] The outer diameters of the limiting support ring 44 and the intermediate ring 46 are the same, so that the outer walls of the intermediate ring 46 and the limiting support ring 44 are close to the inner wall of the seeding drum 27, which helps the seeding drum 27 to rotate smoothly.

[0074] The seeds in the temporary seed storage hopper 10 enter the interior of the sowing drum 27 through the corrugated elbow 9, and as the sowing drum 27 rotates, the inner wall of the sowing drum 27 drives the seeds to move upward, and after moving up a certain distance, the seeds fall again under the action of their own gravity, thereby stirring the seeds, and the diverter plate 47 can also play a stirring role on the seeds at this time, preventing the seeds from sticking into blocks and causing the seeds to be unable to leak out through the sowing drum 28;

[0075] When the sowing drum 27 rotates, the middle ring 46 is always in a stationary state, and when the leakage gap 48 at the lower end of the middle ring 46 is connected with the corresponding leakage hole 49, the seeds in the sowing drum 27 enter the corresponding sowing barrel 28 through the leakage gap 48 and the leakage hole 49 in turn, and fall into the ground soil through the sowing barrel 28 to complete the sowing.

[0076] When the film is punctured at the bottom of the sowing barrel 28 to enter the soil, in order to prevent the ground soil from clogging the sowing barrel 28, a duckbill furrow opener covering the outer side of the bottom of the sowing barrel 28 can be provided on the sowing drum 27. The duckbill furrow opener utilizes a unique duckbill shape design to puncture the film and then dig a pit in the soil, and sow the seeds along the pit into the soil.

[0077] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
