Description

Technical Field

[0001] The present invention relates to the field of sowing equipment, and more particularly to a sowing equipment and a sowing method for rice planting. Background Art

[0002] Traditional rice planting requires four steps: raising seedlings, pulling seedlings, transporting seedlings and transplanting seedlings. The whole process consumes a lot of manpower and material resources, resulting in low rice planting efficiency. With the development of agricultural technology, various rice direct seeding machines have appeared on the market. They can directly sow germinated seeds into rice fields, reducing the steps of rice planting and improving planting efficiency.

[0003] However, the rice direct seeding machines in the prior art are relatively large in size and are not suitable for the needs of sowing in small areas.

[0004] A Chinese patent with authorization announcement number CN204733568U discloses a rice planting machine and provides a technical solution. A baffle is provided on the outer periphery of the upper side of a base plate, and a seed box and a fertilizer box are provided laterally on the upper side thereof. The seed boxes and fertilizer boxes are distributed 1-8 in the longitudinal direction and are arranged correspondingly respectively. Support wheels are provided at both ends of the lower side of the base plate, and a furrow opener connected to the box body is provided at the bottom of each seed box and fertilizer box. A soil covering wheel is provided at the rear part of the lower side of the base plate, and there is one soil covering wheel corresponding to the rear side of each group of seed boxes and fertilizer boxes.

[0005] Although the above patent can meet the needs of small-area planting, it is impossible to control the number of seeds and the amount of fertilizer during the sowing process, resulting in over-dense rice planting and uneven nutrient absorption by individual plants, leading to weak plants, small ears, and a high rate of empty and barren crops in the later stage, thus affecting the yield.

[0006] Therefore, a kind of rice planting sowing equipment and sowing method are proposed. Summary of the invention

[0013] Furthermore, the material distribution mechanism includes two support rods symmetrically arranged at the lower end of the partition, and the left and right ends of the two support rods are rotatably connected to the discharge pipe, and the annular outer sides of the two support rods are symmetrically fixedly connected with baffles.

[0014] Furthermore, the left ends of the two support rods penetrate to the outside of the discharge pipe, and the annular outer side surfaces of the two support rods are fixedly sleeved with mutually meshing gears near the left side, the left end of the front support rod is fixedly connected to a baffle rod, and the left side surface of each of the rotating wheels is fixedly connected with eight push rods in an equidistant manner in a ring shape corresponding to the notches near the edge position.

[0015] Furthermore, a number of traction lines are horizontally and equidistantly fixedly connected to the side surface of each baffle, and counterweight blocks are provided on the front and rear sides of the discharge pipe. The traction lines on the front and rear sides respectively pass through the circular holes opened on the front and rear sides of the discharge pipe and are fixedly connected to the counterweight blocks at corresponding positions.

[0016] Furthermore, the pushing mechanism includes a pillar slidably inserted at the bottom of each slot, one end of the pillar located inside the slot is fixedly connected to a push plate matching the slot, a spring is sleeved on the pillar between the push plate and the bottom of the slot, and each of the rotating wheels is provided with eight column grooves equidistantly arranged in a ring near the center position for the movement of the pillar.

[0017] Furthermore, one end of each of the pillars located in the column groove is fixedly connected to a connecting plate, and the right end of the connecting plate is fixedly connected to a protrusion with a circular structure, each of the rotating wheels is symmetrically provided with grooves with annular groove structures on the left and right sides, and a retaining ring is rotatably connected in the groove through a bearing, the annular inner side surface of each retaining ring is fixedly connected to a retaining ring with a circular ring structure, and the retaining ring on the right side of each rotating ring is provided with a first groove, a second groove and a third groove, and a scraper is fixedly connected to the rear center of the upper end surface of the support plate.

[0019] Furthermore, a pressure plate is fixedly connected to the center position of the upper end surface of each ditching plate, and the pressure plate extends to one end of the frame to form a T-shaped structure. A limiting plate matching the T-shaped structure of the pressure plate is fixedly connected to the upper end surface of the support plate.

[0020] A sowing method of a rice planting sowing device comprises the following steps:

[0021] S1: Put the fertilizer into the space behind the material box partition, and put the rice seeds into the space in front of the partition. Pull the frame to drive the whole equipment to move. During the movement, when the notch on the wheel passes under the feeding pipe, the material distribution mechanism is triggered, so that the fertilizer and rice seeds are transported to the notch at the same time.

[0022] S2: When the notch rotates to the ground along with the wheel, the pushing mechanism in the notch pushes the fertilizer and rice seeds into the rice field to complete the sowing;

[0023] S3: When the equipment is moving, it will drive the furrowing plate to push away the soil between two adjacent rows of rice seeds, thus forming a furrow.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides a material distribution mechanism in a feeding tube and opens a notch on the outer side of a rotating wheel ring. When the notch rotates to the bottom of the feeding tube with the rotating wheel, the push rod on the rotating wheel pushes the baffle rod on the supporting rod, so that the two baffles rotate downward, so that the fertilizer and the rice seeds fall into the notch at the same time. After the notch passes the feeding tube, the two baffles are reset to prevent the fertilizer and the rice seeds from continuously falling, thereby forming a quantitative sowing effect, avoiding over-dense sowing of rice seeds, improving the yield, and saving fertilizer at the same time.

[0026] 2. The present invention provides a pushing mechanism in the notch. When the notch containing fertilizer and rice seeds rotates to the ground, the protrusion separates from the fiber of the first groove and the spring rebounds, thereby driving the push plate to push the fertilizer and rice seeds into the rice field together, preventing the rice seeds from floating on the surface of the rice field, allowing the roots of the rice to grow deeper in the later stage, improving the adhesion between the rice roots and the soil, and further improving the rice's ability to resist lodging.

[0027] 3. The present invention arranges furrowing plates between the wheels, which can push the soil between two adjacent rows of rice to both sides during the sowing process of the equipment, thereby forming furrows, which can effectively drain water, ensure the water level in the rice field, maintain the moisture environment required for rice growth, increase the aeration of the rice root system, allow the rice root system to better absorb oxygen, improve the nutrient absorption efficiency of the rice, and ensure the healthy growth of the rice.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 7 , a rice planting sowing equipment, comprising a frame 2, a support plate 23 is fixedly connected to the bottom of the front side of the frame 2, and a frame plate 24 is symmetrically fixedly connected to the left and right sides of the support plate 23, a fixed shaft 1 is rotatably inserted between the two frame plates 24, and the left and right ends of the fixed shaft 1 are fixedly connected to walking wheels by bolts, and a plurality of groups of running wheels 3 are sleeved on the fixed shaft 1, and each of the running wheels 3 is symmetrically fixedly connected to a fixing plate 37 near the center position on the left and right sides, and the fixing plate 37 is fixedly connected to the screw hole opened on the fixed shaft 1 by screws, and eight notches 31 are equidistantly opened on the annular outer side surface of the running wheel 3, and a material box 6 is provided above each of the running wheels 3, and the rear side surface of the material box 6 is fixedly connected to an L-shaped bracket 71, and the lower end of the bracket 71 is a T-shaped structure, and the upper end surface of the frame 2 is fixedly connected to a slide rail 7 matching the T-shaped structure at the lower end of the bracket 71;

[0039] The lower end of the material box 6 is connected to a feed pipe 62, a material distribution mechanism is provided in the feed pipe 62, and a pushing mechanism is provided in the notch 31;

[0040] The lower end of the material box 6 is communicated with a blanking pipe 62. A semi-circular ring-shaped housing 63 is sleeved on the rear half of the outer circumferential surface of each runner 3. The discharge port at the lower end of the blanking pipe 62 is communicated with the housing 63 and has the same size as the notch 31. A partition 61 is fixedly connected to the central position inside the material box 6. The material distribution mechanism includes two support rods 67 symmetrically arranged before and after at the lower end of the partition 61. The left and right ends of the two support rods 67 are rotatably connected to the blanking pipe 62. Baffles 64 are symmetrically and fixedly connected to the outer circumferential surfaces of the two support rods 67. The left ends of the two support rods 67 penetrate to the outside of the blanking pipe 62. Gears that mesh with each other are fixedly sleeved on the outer circumferential surfaces of the two support rods 67 near the left side. A stop rod 66 is fixedly connected to the left end of the front support rod 67. Eight push rods 38 are fixedly connected to the left side surface of each runner 3 near the edge corresponding to the notch 31 at equal circumferential intervals.

[0041] By adopting the above technical solution, the frame 2 is in a U-shaped structure. Two sockets 21 are symmetrically opened on the rear side surface of the frame 2. A carrier plate 22 is fixedly connected inside the frame 2. A fertilizer tank and a rice seed tank are respectively slidably inserted into the two sockets 21. The fertilizer tank is used to hold fertilizer and replenish it when the fertilizer in the material box 6 is insufficient. The rice seed tank holds rice seeds and replenishes the rice seeds when the rice seeds in the material box 6 are insufficient. The bottom of the rear side surface of the frame 2 is in a structure that bends upward. On the one hand, it can level the surface of the paddy field. On the other hand, it can prevent the frame 2 from piercing into the ground to reduce the resistance during walking. The support 71 and the housing 63 slide synchronously with the runner 3 onto the fixed shaft 1. The T-shaped structure at the lower end of the support 71 slides along the slide rail 7 synchronously. A plurality of screw holes are horizontally and equally opened on the outer circumferential surface of the fixed shaft 1. The distance between two adjacent runners 3 can be adjusted according to the plant spacing requirements between different varieties of rice to improve the scope of application. After determining the plant spacing, the runner 3 and the fixed shaft 1 are fixed by screws in cooperation with the fixing plate 37. Screw holes are also opened on the slide rail 7. The support 71 and the slide rail 7 are fixed by screws to prevent the material box 6 from shaking during the sowing process.

[0042] A diesel engine can be installed on the frame 2, and a belt transmission mechanism is set between the diesel engine and the fixed shaft 1 to drive the entire equipment to move, so as to save manpower. After the equipment as a whole enters the rice field, the fertilizer is placed in the space behind the partition 61 inside the material box 6, and the rice seeds are placed in the space in front of the partition 61. When the push rod 38 does not contact the baffle 66, the two baffles 64 in the feed pipe 62 just block the feed pipe 62, thereby ensuring that the fertilizer and rice seeds will not accumulate in the feed pipe 62 during the process of entering the material box 6. After the material box 6 is filled with fertilizer and rice seeds, the fixed shaft 1 and the travel wheel are driven to move in reverse. When the push rod 38 on the rotating wheel 3 touches the baffle 66, the front support rod 67 starts to rotate clockwise, thereby driving the rear support rod 67 to rotate counterclockwise, thereby causing the two baffles 64 to gradually flip downward, so that the fertilizer and rice seeds fall downward at the same time. When the notch 31 just reaches the bottom of the feeding pipe 62, the push rod 38 leaves the baffle 66. A torsion spring is installed on the front support rod 67. When the baffle 66 loses the limit of the push rod 38, the torsion spring drives the front support rod 67 to rotate counterclockwise to reset, thereby driving the rear support rod 67 clockwise. The hour hand rotates to reset, and then drives the two baffles 64 to reset to prevent the fertilizer and rice seeds from falling further, ensuring the feeding amount of fertilizer and rice seeds, avoiding over-dense sowing of rice seeds and excessive fertilization, ensuring that the rice seeds fully absorb nutrients, and saving fertilizer usage. In addition, a number of traction lines 68 are fixedly connected horizontally and equidistantly on the side surface of each baffle 64, and counterweight blocks 65 are provided on the front and rear sides of the feeding tube 62. The traction lines 68 on the front and rear sides respectively pass through the circular holes on the front and rear sides of the feeding tube 62 and are fixedly connected to the counterweight blocks 65 at the corresponding positions, so that the two baffles 64 will be pulled in the process of turning downward. The traction line 68 is movable. The traction line 68 can also separate the fertilizer and the rice seeds in the process of pulling the counterweight block 65 upward, so that the fertilizer and the rice seeds are dispersed, so as to facilitate falling, and avoid the fertilizer and the rice seeds from piling up and being inconvenient to pass through the feeding pipe 62, so as to ensure the normal sowing. Moreover, after the blocking rod 66 loses the limit of the push rod 38, the counterweight block 65 falls downward, thereby pulling the traction line 68, and then pulling the baffle 64 upward, and then cooperating with the rebound effect of the torsion spring, so that the two baffles 64 can be quickly reset, and the fertilizer and the rice seeds are blocked from falling in time, so as to improve the accuracy of the fertilizer and rice seed feeding amount;

[0043] After the fertilizer and rice seeds enter the slot 31, the slot 31 continues to rotate counterclockwise with the wheel 3. At this time, the slot 31 enters the casing 63, and the casing 63 shields the slot 31 to prevent the fertilizer and rice seeds from falling prematurely during the rotation process. When the slot 31 rotates to the surface of the rice field, the slot 31 separates from the casing 63. At this time, the pushing mechanism plays a role in pushing the fertilizer and rice seeds into the rice field, thereby completing sowing and fertilizing, killing two birds with one stone, improving sowing efficiency, and saving the subsequent manual fertilization steps, saving costs while improving work efficiency.

[0044] like Figures 1 to 6 As shown, the pushing mechanism includes a pillar 33 slidably inserted at the bottom of each slot 31, one end of the pillar 33 located inside the slot 31 is fixedly connected to a push plate 32 matching the slot 31, a spring is sleeved on the pillar 33 between the push plate 32 and the bottom of the slot 31, each of the rotating wheels 3 is annularly and equidistantly provided with eight column grooves 36 for the movement of the pillar 33 near the center position, one end of each of the pillars 33 located in the column groove 36 is fixedly connected to a connecting plate 34, and the right end of the connecting plate 34 is fixedly connected to a protrusion 35 with a circular structure, each of the rotating wheels 3 is symmetrically provided with a groove 4 with an annular groove structure on the left and right sides, and a snap ring 41 is rotatably connected in the groove 4 through a bearing, the annular inner side surface of each snap ring 41 is fixedly connected to a snap ring 42 with an annular structure, and the snap ring 42 on the right side of each rotating ring is provided with a first groove 43, a second groove 44 and a third groove 45, and a scraper 25 is fixedly connected to the rear center of the upper end surface of the support plate 23.

[0045] By adopting the above technical solution, the protrusion 35 is always restricted in the circle formed by the first groove 43, the second groove 44 and the third groove 45. The first groove 43 occupies the front half of the clamping ring 42, the third groove 45 is located in the area where the shell 63 is located, and the second groove 44 is located at the bottom intersection of the first groove 43 and the third groove 45. When the slot 31 rotates in the area where the shell 63 is located, the protrusion 35 is squeezed and limited by the third groove 45, so that the push plate 32 is pulled into the slot 31 by the support 33, and the spring is compressed, thereby ensuring that the fertilizer and rice seeds are always in the slot 31. When the protrusion 35 just rotates to the position of the second groove 44, the protrusion 35 suddenly loses its limit, and the spring rebounds and resets, thereby driving the support 33 to push the push plate 32 out of the slot 31 to 3 cm underground, and then driving the push plate 32 to push the fertilizer and rice seeds out of the slot 31 together. Since the rice field is muddy, the push plate 3 2 is easily pushed into the mud, so that fertilizers and rice seeds can enter the ground, preventing rice seeds from floating on the surface of the rice field, so that the roots of the rice in the later stage are deeply rooted, improving the adhesion of the rice roots to the soil, and thus improving the anti-lodging ability of the rice. When the protrusion 35 rotates to the first groove 43, the protrusion 35 is compressed and limited again. At this time, the push plate 32 is pulled back to the notch 31 and is flush with the notch 31, so as to prevent soil from accumulating inside the notch 31 and affecting the subsequent entry of fertilizers and rice seeds. The scraper 25 is arranged at the front side of the rotating wheel 3. When the notch 31 passes through the scraper 25, the scraper 25 can scrape the position of the notch 31 to prevent the soil from sticking to the rotating wheel 3. When the protrusion 35 rotates close to the bottom of the feeding pipe 62, the protrusion 35 is compressed and limited by the third groove 45 again, so that the push plate 32 is pulled back to the notch 31 again, so as to facilitate the entry of fertilizers and rice seeds. This is repeated to complete the sowing of rice seeds.

[0046] like Figure 4 , Figure 7 As shown, a ditching plate 5 is provided between each two adjacent wheels 3, and two plate sleeves 53 are hinged symmetrically on the upper end surface of the ditching plate 5, and an insert plate 54 is elastically connected to the plate sleeve 53 through a spring, and the end of the insert plate 54 away from the plate sleeve 53 is hinged to the outer side surface of the clamping ring 42 at the corresponding position, and a pressure plate 51 is fixedly connected to the center position of the upper end surface of each ditching plate 5, and the pressure plate 51 extends to one end of the frame 2 to form a T-shaped structure, and the upper end surface of the support plate 23 is fixedly connected to a limit plate 52 matching the T-shaped structure of the pressure plate 51.

[0047] By adopting the above technical solution, during the installation of the rotating wheel 3, the T-shaped structure of the pressing plate 51 is synchronously inserted into the sliding groove of the limiting plate 52 and fixed to the limiting plate 52 by screws, thereby ensuring that the furrowing plate 5 will not shake during the sowing process. Since the end of the inserting plate 54 away from the plate sleeve 53 is hinged to the outer side surface of the clamping ring 42 at the corresponding position, the clamping ring 41 is rotatably connected to the clamping groove 4 through the bearing, thereby ensuring that the clamping ring 41 and the clamping ring 42 will not rotate during the rotation of the rotating wheel 3, thereby ensuring the normal operation of the pushing mechanism, and the furrowing plate 5 will push the two adjacent The soil between the rows of rice seeds is pushed away to form ridges, which can effectively drain water, ensure the water level in the rice field, maintain the moisture environment required for rice growth, increase the aeration of the rice root system, allow the rice root system to better absorb oxygen, improve the nutrient absorption efficiency of rice, and ensure the healthy growth of rice. The plug plate 54 is elastically connected to the bottom surface of the plate sleeve 53 through a spring. When the spacing between the wheels 3 needs to be adjusted, the plug plate 54 can slide in the plate sleeve 53, thereby ensuring that the position of the ditching plate 5 in the vertical direction remains unchanged, thereby ensuring that the depth of the ditching remains unchanged.

[0048] A sowing method of a rice planting sowing device comprises the following steps:

[0049] S1: Fertilizer is placed in the space behind the partition 61 of the material box 6, and rice seeds are placed in the space in front of the partition 61. The frame 2 is pulled to drive the entire device to move. During the movement, when the notch 31 on the wheel 3 passes under the feeding pipe 62, the material distribution mechanism is triggered, thereby simultaneously transporting the fertilizer and rice seeds into the notch 31;

[0050] S2: When the slot 31 rotates to the ground along with the wheel 3, the pushing mechanism in the slot 31 pushes the fertilizer and rice seeds into the rice field to complete the sowing;

[0051] S3: During the movement of the equipment, the furrowing plate 5 will be driven to push away the soil between two adjacent rows of rice seeds, thereby forming a furrow.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
