[0058] Ridges are formed on both sides of the seed furrow by a ridging device 600;

[0059] The soil pushed away by the furrow opening device 500 is piled toward the middle by the soil covering device 700 to cover the seed furrow and the seeds therein;

[0060] The soil covering the seed furrow is compacted by the compaction device 800 .

[0061] Embodiment 2: Figures 1 to 27As shown, a bean seeder is different from its embodiment 1 in that: the frame 100 includes a frame 110, and the walking device 200, the loosening device 300, the seeding device 400, the ridging device 600, the covering device 700, the pressing device 800 and the driving device 900 are all installed on the frame 110, the loosening device 300 is rotatably installed at the front of the frame 110, the seeding device 400 is installed in the middle of the frame 110, the ridging device 600 is installed at the bottom of the frame 110, and the covering device 700 is installed at the lower rear of the frame 110, and an armrest 120 is provided above the rear of the frame 110; the driving device 900 includes an internal combustion engine 910 and a plurality of transmission mechanisms, and the internal combustion engine 910 drives the walking device 200, the loosening device 300, the seeding device 400 and the covering device 700 through the plurality of transmission mechanisms respectively.

[0062] The frame 110 of the frame 100 serves as a supporting part for all working parts, and the internal combustion engine 910 is preferably but not limited to a diesel engine. The multiple transmission mechanisms preferably include but are not limited to a first chain transmission mechanism 920, a second chain transmission mechanism 930, a third chain transmission mechanism 940, a fourth chain transmission mechanism 950, a gear transmission mechanism 960 and a cam transmission mechanism 970. The output end of the internal combustion engine 910 is connected to the first chain transmission mechanism 920. The first chain transmission mechanism 920 drives the walking device 200 and the loosening device 300 to work through the second chain transmission mechanism 930. The first chain transmission mechanism 920 drives the seeding device 400 to work through the gear transmission mechanism 960. The first chain transmission mechanism 920 drives the front cam transmission mechanism 970 through the third chain transmission mechanism 940. The front cam transmission mechanism 970 drives the front soil covering clamp in the front soil covering device 700 to work. The third chain transmission mechanism 940 drives the rear cam transmission mechanism 980 through the fourth chain transmission mechanism 950. The rear cam transmission mechanism 980 drives the rear soil covering clamp in the front soil covering device 700 to work.

[0063] Embodiment 3: Figures 1 to 27 As shown, a bean seeding machine is different from the first or second embodiment in that the walking device 200 includes two load-bearing wheels 210 and two universal wheels 220, the two load-bearing wheels 210 are symmetrically mounted on the left and right sides of the front of the frame 100, and the two universal wheels 220 are symmetrically mounted on the left and right sides of the rear of the frame 100, the loosening device 300 is mounted between the two load-bearing wheels 210, and the walking device 200 and the loosening device 300 are synchronously driven by the driving device 900. The load-bearing wheels 210 can support most of the weight of the seeding machine, and the universal wheels 220 can achieve steering, so that farmers can perform seeding work more easily and efficiently.

[0064] The load-bearing wheel 210 includes a first wheel hub and a first tire mounted on the first wheel hub, and the first wheel hub is rotatably mounted on the front inner side of the frame 100 (specifically, the above-mentioned frame 110); the universal wheel 220 includes a second wheel hub and a second tire mounted on the second wheel hub, and the second wheel hub can be rotatably mounted on a universal bracket 221, and the top of the universal bracket 221 can be horizontally rotatably mounted on the rear bottom side of the frame 100 (specifically, the above-mentioned frame 110). The two ends of the central axis of the loosening device 300 are respectively fixedly connected to the wheel axles of the two first wheel hubs, and the central axis of the loosening device 300 can be driven to rotate by the above-mentioned second chain transmission mechanism.

[0065] Embodiment 4: Figures 1 to 27 As shown, a bean planter is different from its embodiment one, two or three in that: the loosening device 300 includes a loosening wheel 310, and the loosening wheel 310 can be made of a thin steel plate. The loosening wheel 310 includes a roller 311 and digging teeth 312 evenly arranged along the circumference of the roller 311, such as 10 rows of digging teeth 312, 8 digging teeth 312 in each row, and the digging teeth 312 are preferably but not limited to being in an arc shape. The digging teeth 312 can be inserted into the soil to a certain depth. Because each digging tooth 312 is angled (the front angle of the digging tooth 312 is an acute angle, such as 60 to 80°), the digging teeth 312 can drive the soil to loosen while the roller 311 rotates, thereby achieving the purpose of loosening the soil.

[0066] In this embodiment, the loosening wheel 310 can loosen the shallow soil before sowing, thereby improving the quality of the soil. Deep tillage (about 20 cm below the soil) is the basis, and shallow loosening (about 10 cm above the soil surface) is to retain moisture. The role of the loosening wheel 310 is to pre-treat the soil, so that the soil is finer and softer, and the water can be more easily retained in the soil, thereby improving the quality of seedling emergence.

[0067] Embodiment 5: Figures 1 to 27As shown, a bean seeder is different from the first, second, third or fourth embodiments thereof in that: the seeding device 400 includes a seed barrel 410, a stirrer 420, a dial 430 and a seeding tray 450, the bottom of the seed barrel 410 is provided with two funnels 411 symmetrically distributed on the left and right, the fixed end (specifically a stand) of the stirrer 420 is fixed on the frame 100 (specifically the above-mentioned frame 110), and the stirring end (specifically a propeller) of the stirrer 420 extends into the seed barrel 410. In the barrel 410, the two funnels 411 are fixed on the dial 430 together, and the left and right ends of the dial 430 are symmetrically provided with a plurality of first seed holes 431 spaced apart from each other. The left and right ends of the dial 430 are respectively provided with plug holes 432 that penetrate all the first seed holes 431 at the corresponding ends, and the plug holes 432 are inserted with plug plates 440 for controlling the number of working first seed holes 431. The outer end of the plug plate 440 is provided with a sliding hole 441 along its length direction. The plug plate 440 is fixed to the dial 430 by a first bolt 442 and a corresponding first nut 443 that are slidably matched with the sliding hole 441. The first nut 443 can be loosened before adjusting the position of the plug plate 440, and the first nut 443 can be tightened after adjusting the position of the plug plate, which is very convenient for adjustment. The bottom of the dial 430 is rotatably mounted on the seeding disk 450, and the left and right ends of the seeding disk 450 are symmetrically provided with a plurality of second seeding holes 451 corresponding to the first seeding holes 431 at the corresponding ends. The seed tray 450 is fixed on the frame 100 (specifically, the above-mentioned frame 110), and two seed discharge tubes 460 connected to all the second seed discharge holes 451 at the corresponding ends are symmetrically arranged below the left and right ends of the seed tray 450. The seed discharge tubes 460 can be fixed on the frame 100 (specifically, the above-mentioned frame 110) or the bottom of the seed tray 450, and the lower end of the seed discharge tube 460 is tilted backward, and the furrowing device 500 is installed at the lower part of the seed discharge tube 460 and is height-adjustable.

[0068] The inclination angle of the funnel 411 is slightly larger than the sliding friction angle of beans and other plant seeds, which can ensure that the seeds can smoothly fall into the seed discharge tube 460 without accumulation. The stirrer 420 is stationary relative to the frame 100. When the seed barrel 410 rotates, the stirrer 420 stirs the seeds, which mainly prevents the seeds from getting stuck. The dial 430 and the seed barrel 410 rotate together, so the two are fixedly connected (such as welded) as a whole; the vertical rotating shaft 433 fixedly installed at the bottom of the dial 430 provides support and driving force for the dial 430 and the seed barrel 410. The vertical rotating shaft 433 and the axial hole of the seed plate 450 rotate in cooperation, and a driven bevel gear 962 is fixedly installed at the lower end of the vertical rotating shaft 433. The driven bevel gear 962 is meshed with an active bevel gear 961. The driven bevel gear 962 and the active bevel gear 961 constitute the above-mentioned gear transmission mechanism, so that the dial 430 rotates with the power output by the driving device 900. Therefore, the first seed hole 431 on the dial 430 not only has the function of seed discharge, but also can scrape off the seeds that want to continue to enter the seed plate 450. This design utilizes the rotation of the dial 430 itself, which can not only dredge the seeds, but also reduce the load of the seed barrel 410, thereby improving the service life of the seed discharge device 400.

[0069] Among them, the shape and size of the first seed hole 431 and the second seed hole 451 are determined by the shape and size of the seeds to be sown. The number of the first seed hole 431 and the second seed hole 451 is preferably but not limited to 3. If the farmer has other needs and does not need 3 seeds, the first seed hole 431 can be covered by moving the plug plate 440 left and right to achieve a change of 0 to 3 seeds. Considering that there is still a height difference in the dial 430, the plug plate 440 is placed inside the dial 430 to block the falling of seeds from the source and prevent the phenomenon of stuck seeds. Before sowing, the farmer can adjust the position of the plug plate 440 in the seeding device 400 to select the required number of sowing grains according to the requirements, thereby improving the flexibility of the seeder and enhancing the adaptability to agronomic requirements. The seeding device 400 is a mechanical seeding device with a simple structure, which can directly realize double-row sowing on the ridge, and is particularly suitable for double-row planting on the ridge of crops such as soybeans.

[0070] The seed tray 450 is a key component for the seeds in the seed barrel 410 to fall into the seed discharge tube 460, and also plays a role of "intermediary" and "conduction". The difference between the seed tray 450 and the dial 430 is that the former is fixed on the frame 100. When the second seed discharge hole 451 on the seed tray 450 is aligned with the first seed discharge hole 431 on the dial 430, the seeds have an outlet, and rely on their own gravity to pass through the seed tray 450 and fall into the seed discharge tube 460. The function of the seed discharge tube 460 is to introduce the seeds discharged from the seed tray 450 into the furrow opener, like a bridge between the seed tray 450 and the furrow opener; the inner wall of the seed discharge tube 460 should be smooth so that the seeds doing falling motion are not blocked, and can adapt to the position of the furrow opener that can be adjusted up and down. In order to make most of the seeds fall freely, the inclination angle of the seed tube 460 should be tilted backward (because the seed drill moves forward continuously); the seed tube 460 is preferably but not limited to be made of metal, and the backward inclination angle of the lower end is preferably but not limited to 30°. The advantage of this design is that the seeds have a backward speed when falling, and the horizontal component speed can reduce the landing speed of the last seeds, so that the seeds will not bounce and roll when falling into the seed furrow, reducing the probability of uneven planting.

[0071] Example 6: Figures 1 to 27 As shown, a bean planter is different from its embodiments one, two, three, four or five in that: the furrowing device 500 includes a V-shaped furrow opener 510, and the furrow opener 510 is height-adjustably installed at the lower part of the seed discharge device 400. Since the height position of the furrow opener 510 is adjustable, it can open seed furrows of different depths to meet various agronomic requirements; the pointed head of the furrow opener 510 faces forward, and the pointed head part can push the soil open, that is, the front ends of the blades on both sides of the furrow opener 510 are fixedly connected into one and form a front end blade. The front end blade of the furrow opener 510 is in a circular arc shape that is concave backwards, and the front end has a tendency to enter the soil by itself, so that it can be inserted deeper into the soil and discharge the soil to both sides. The overall structure is compact and the furrow bottom formed is flat.

[0072] In this embodiment, the furrow opener 510 preferably but not limited to adopts the following height adjustable structure: long holes 511 (such as two upper and lower ones) are opened on both blades of the furrow opener 510, and the blades on both sides are respectively locked on the seeding device 400 (specifically, it can be on the seeding tube 460) through bolts passing through the corresponding long holes 511; of course, the long holes 511 can also be opened on the seeding device 400 (specifically, it can be on the seeding tube 460). The inner wall of the seed furrow opened by the V-shaped furrow opener 510 is flat and the depth is consistent, which improves the efficiency and quality of sowing and meets the agronomic requirements of the double-row planting technology on the ridge.

[0073] Embodiment 7: Figures 1 to 27As shown, a bean seeding machine is different from the first, second, third, fourth, fifth or sixth embodiment thereof in that: the ridging device 600 includes a V-shaped ridging device 610, the ridging device 610 includes a left push plate 611 and a right push plate 612, the front end of the left push plate 611 is hinged with the front end of the right push plate 612, and an adjustable telescopic mechanism 620 is connected between the right middle of the left push plate 611 and the left middle of the right push plate 612, and the width of the ridging device 610 can be adjusted by the adjustable telescopic mechanism 620, and large or small ridges can be opened according to the needs of farmers, so as to better realize the integration of the seeding machine. The upper end of the hinge shaft 613 between the left push plate 611 and the right push plate 612 can be directly fixed on the frame 100 (specifically, it can be the above-mentioned frame 110).

[0074] The adjustable telescopic mechanism 620 is preferably but not limited to a telescopic rod, and the telescopic rod can adopt but not limited to the following structure: the telescopic rod includes an outer rod 621, an inner rod 622, a boss 623 and a limit nut 624, one end of the outer rod 621 is hinged to one of the left push plate 611 and the right push plate 612, one end of the inner rod 622 is hinged to the other of the left push plate 611 and the right push plate 612, the other end of the inner rod 622 is inserted into the other end of the outer rod 621, the outer side wall of the outer rod 621 is provided with an external thread extending to the other end of the outer rod 621, and the side wall of the outer rod 621 is provided with a There is a slide groove extending to the other end of the outer rod 621, and the boss 623 is fixed on the outer side wall of the other end of the inner rod 622 and slidably cooperates with the slide groove. The limit nut 624 is sleeved on the external thread of the outer rod 621 to limit the boss 623 from sliding out of the slide groove. The position of the boss 623 can be adjusted by adjusting the position of the limit nut 624. The boss 623 ensures the maximum limit, and the limit nut 624 ensures the minimum limit. The ridge width can be adjusted at will within this range. At the same time, the presence of the boss 623 and the limit nut 624 prevents the ridger 610 from slipping due to external pressure, so high-quality ridges with consistent ridge spacing and smooth soil surface can be opened, and the lines are straight and not crooked.

[0075] The ridger 610 does not need to be driven by power, which saves costs. Because in actual planting operations, multiple crops often need to be planted on the same piece of land so that land resources can be maximized, which requires different ridge heights and ridge furrows of different widths, so an adjustable telescopic mechanism 620 is connected between the left push plate 611 and the right push plate 612, and different angle widths between the left push plate 611 and the right push plate 612 are achieved by adjusting the length of the adjustable telescopic mechanism 620, thereby adjusting different ridge widths, which can maximize the utilization of land resources.

[0076] Embodiment 8: Figures 1 to 27As shown, a bean planter is different from its embodiments one, two, three, four, five, six or seven in that: the soil covering device 700 includes a front soil covering clamp 710 and a rear soil covering clamp 720, and the front soil covering clamp 710 and the rear soil covering clamp 720 both include a left clamp 701 and a right clamp 702, and the middle parts of the left clamp 701 and the right clamp 702 are symmetrically hinged on a fixed seat 703, and the fixed seat 703 is fixed on a frame 100 (specifically, the above-mentioned frame), and the upper ends of the left clamp 701 and the right clamp 702 are slidably hinged on a lifting rod 704, and the lifting rod 704 is driven by a driving device 900 (specifically, a corresponding cam transmission mechanism).

[0077] Among them, the above-mentioned cam transmission mechanism all includes a cam 971, and the cam 971 cooperates with the lifting rod 704 to form a cam-guide rod mechanism. The lifting rod 704 is driven to move up and down by the cam 971, and the simple opening and closing action of the front soil covering clamp 710 and the rear soil covering clamp 720 is realized by the up and down movement of the lifting rod 704, so that the soil on both sides is squeezed and closed toward the middle, thereby realizing the soil covering work.

[0078] The soil covering device 700 is in the form of a clamp, and is arranged in two rows, front and back, to ensure that all the seed furrows are covered with soil. When not working, the front soil covering clamp 710 is in a "clamped state" and the rear soil covering clamp 720 is in a "separated state"; when working, the front soil covering clamp 710 is in a "separated state" and the rear soil covering clamp 720 is in a "clamped state"; the cam-guide rod mechanism drives the front soil covering clamp 710 and the rear soil covering clamp 720 to perform a squeeze and close movement, and the cycle repeats. The opening and closing movement of the front soil covering clamp 710 and the rear soil covering clamp 720 allows the soil pushed away by the furrow opener 510 to accumulate in the middle. The open design makes the soil covering device 700 not easy to be blocked, and the soil covering thickness can meet the planting requirements. Since the previous soil is re-covered, the surrounding soil structure will not be changed, and the growth environment of the seeds will not be damaged.

Among them, the elastic mechanism 840 is preferably but not limited to a spring support.

[0080] The pressing wheel 810 is preferably, but not limited to, a composite pressing wheel of a cylinder + a rubber sleeve, which has the dual characteristics of rigidity and elasticity. During operation, the pressing wheel 810 can be deformed and restored alternately through the elastic deformation ability of the rubber sleeve, and can elastically recover after being compressed, and the pressure on the soil is also constant. The pattern on the outer surface of the rubber sleeve can reduce the slipping phenomenon during the pressing process, and the cylindrical pressing wheel 810 has a wide contact surface with the soil, which greatly reduces the uneven pressing pressure.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field without departing from the content of the technical solution of the present invention according to the technical essence of the present invention shall fall within the scope of the present invention.
