Description

Technical Field

[0001] The invention belongs to the technical field of sowing devices, in particular to a quantitative sowing device for soybean planting. Background Art

[0002] Soybean is one of the most planted crops in agriculture. In the past, manual sowing was used, but it was inefficient and not suitable for large-scale planting. Therefore, seeders were developed. Among them, drum seeders are widely used because of their ease of use. They use a rotating drum to dig holes in the ground and plant the seeds. The process only requires pushing the seeder forward to roll.

[0003] A patent with the announcement number CN111990024B discloses an adjustable soybean seed precision seeder. The device is provided with a single grain outlet to cooperate with a grain dividing ring, and grain grooves are evenly opened on the grain dividing ring. Seed particles can only fall into the grain grooves. Compared with the prior art, the size of the grain outlet and the grain groove can only accommodate one seed. When the grain outlet is rotated to the point where no grain groove is matched with the grain outlet, the grain cannot be discharged due to the small gap. In this way, the situation of empty grains and multiple grains is avoided. At the same time, the grains are dropped at the bottom by using the function of the top head, which is convenient and fast. There will be no blockage causing inability to sow, by setting a slidable adjustable adjustment block between the grading ring and the duckbill, and at the same time an adjustment device is set on the front of the adjustment block. Compared with the prior art, the rotation adjustment of the plunger screw acts on the hydraulic oil so that the top column pushes the adjustment block to move and adjust, and the adjustment block can drive the adjustment of the duckbill, so that the extended length of the duckbill can be increased to adapt to different planting depths and land, and when planting on the same land, the plant spacing can also be changed through adjustment, without the need to disassemble the seeder, saving time and improving efficiency.

[0004] There are still some problems in the actual application of the above scheme. Usually, the operator controls the seeder with a handle and pushes the seeder to roll on the ridge. During the rolling process of the seeder, a pair of eagle hook covers are used to discharge soybean seeds in the ridge. However, when this seeder is sowing soybeans, it is impossible to control the number of soybean seeds discharged, which may easily lead to excessive discharge of soybean seeds in one pit, resulting in uneven absorption of nutrients by the soybean seeds in the later stage, thereby affecting the yield of soybeans. Moreover, since the overall balance of the seeder is controlled by the operator, the operator's arm is easily injured during long-term sowing work.

[0005] To this end, the present invention provides a quantitative sowing device for soybean planting. Summary of the invention

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 9 As shown, a quantitative sowing device for soybean planting according to an embodiment of the present invention comprises a circular rotating frame 1, a rotating cylinder 3 is installed in the inner cavity of the circular rotating frame 1, an L-shaped discharge conduit 21 is rotatably connected to one end of the rotating cylinder 3, a storage box 5 is fixedly connected to the upper end of the L-shaped discharge conduit 21, a pushing frame 7 is installed at the lower end of the storage box 5, and a plurality of discharge sowing components 4 are arranged outside the circular rotating frame 1; The discharge sowing assembly 4 includes a plurality of first hook covers 41 fixedly connected to the outside of the circular rotating frame 1 in an annular shape, and a second hook cover 42 is symmetrically arranged on one side of each first hook cover 41, and a rotating shaft 44 is fixedly connected to both ends of the second hook cover 42, and a rotating rod 45 is installed at one end of the rotating shaft 44, which is used to turn the rotating rod 45 to drive the rotating shaft 44 to rotate, so that the rotating shaft 44 can drive the second hook cover 42 to flip open for sowing; A mounting groove 16 is provided on one side of the rotating cylinder 3, and a quantitative sowing assembly 6 is rotatably mounted in the inner cavity of the mounting groove 16; The quantitative sowing assembly 6 includes a first telescopic frame 62 rotatably mounted in the inner cavity of the mounting groove 16, one end of the first telescopic frame 62 is externally slidably connected to a second telescopic frame 63, and the inner cavities of the first telescopic frame 62 and the second telescopic frame 63 are used for quantitatively collecting soybean seeds.

[0023] Specifically, in the prior art, an operator usually controls the seeder with a handle and pushes the seeder to roll on the ridge. During the rolling process of the seeder, the discharge port is used to discharge soybean seeds in the ridge. However, when this seeder is sowing soybeans, since the discharge amount of soybean seeds cannot be controlled, it is easy to cause excessive discharge of soybean seeds in one pit, resulting in uneven absorption of nutrients by the soybean seeds in the later stage, thereby affecting the yield of soybeans. Moreover, since the overall balance of the seeder is controlled by the operator, the operator's arm is easily injured during long-term sowing work. When sowing soybeans, the present invention puts soybean seeds into the storage box 5 for storage, and then uses the pushing frame 7 to push the rotating cylinder 3 to move, so that the rotating cylinder 3 drives the circular rotating frame 1 to rotate. During the rotation of the circular rotating frame 1, it will drive the sowing assembly composed of the first eagle hook cover 41 and the second eagle hook cover 42 to rotate synchronously, so that a sowing hole can be chiseled out on the field ridge during the rotation of the sowing assembly composed of the first eagle hook cover 41 and the second eagle hook cover 42 on the field ridge. During the rotation of the circular rotating frame 1, it will also drive the first telescopic frame 62 to rotate, and then drive the second telescopic frame 63 to rotate. During the rotation of the first telescopic frame 62 and the second telescopic frame 63, the soybean seeds discharged into the inner cavity of the rotating cylinder 3 in the storage box 5 will be received. At the same time, during the rotation of the first telescopic frame 62 and the second telescopic frame 63, the soybean seeds are discharged into the first telescopic cover 41 and In the sowing assembly composed of the second eagle hook cover 42, when the circular rotating frame 1 rotates, the circular rotating frame 1 will also drive the rotating shaft 44 to rotate synchronously, and the rotating shaft 44 will drive the rotating rod 45 to rotate, so that the rotating rod 45 will abut against the second telescopic frame 63 during the rotation of the circular rotating frame 1, and then as the circular rotating frame 1 rotates, the rotating rod 45 drives the rotating shaft 44 to rotate, and the rotating shaft 44 drives the second eagle hook cover 42 to flip, so as to open the soil in the holes chiseled on the ridges, and at the same time, discharge the soybean seeds into the holes for sowing. When it is necessary to control the quantitative sowing of soybean seeds, the second telescopic frame 63 is driven to slide outside the first telescopic frame 62, and then the distance between the first telescopic frame 62 and the second telescopic frame 63 is adjusted, so as to control the number of soybean seeds received between the first telescopic frame 62 and the second telescopic frame 63, so as to achieve quantitative sowing of soybeans, thereby solving the above-mentioned problem.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, a storage chamber 22 is provided inside the rotating cylinder 3, and a sealing cover 17 is rotatably connected to the upper end of the storage box 5. The storage box 5 is arranged in a trapezoidal shape, and is used to guide the soybean seeds in the cavity into the L-shaped discharge conduit 21, and enter the storage chamber 22 for storage. A material guide rack 20 is provided in the inner cavity of the storage chamber 22, and the storage chamber 22 is connected with the inner cavities of the first telescopic rack 62 and the second telescopic rack 63 through the material guide rack 20, and can receive the soybean seeds in the storage chamber 22 as the first telescopic rack 62 and the second telescopic rack 63 rotate.

[0025] Specifically, when the circular rotating frame 1 is pushed by holding the pushing frame 7 for rolling sowing, since the storage box 5 is arranged in a trapezoidal shape, the soybean seeds in the cavity of the storage box 5 can be guided to quickly flow into the L-shaped discharge conduit 21, and then enter the storage cavity 22 through the L-shaped discharge conduit 21. A guide frame 20 is provided in the storage cavity 22, and a discharge port is provided at the lower end of the guide frame 20, so that the soybean seeds can be accurately guided into the inner cavity of the first telescopic frame 62 and the second telescopic frame 63, so that in the process of driving the first telescopic frame 62 and the second telescopic frame 63 to rotate, the soybean seeds can be circulated and received for discharge and sowing, thereby improving the sowing efficiency of soybean planting.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, two clamps 8 are installed on the outside of the pushing frame 7, and a connecting column 9 is fixedly connected between the two clamps 8. The connecting column 9 is externally threaded with a fastening nut and a gasket for fastening the clamps 8.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, the lower end of the clamp 8 is rotatably connected to the support frame 10, and two U-shaped fixed blocks 12 are fixedly connected to one side of the support frame 10. The inner cavity of the U-shaped fixed block 12 is rotatably connected to a rotating block 13, and a tension spring 14 is installed at one end of the rotating block 13. A fixed block 15 is installed at one end of the tension spring 14, and the fixed block 15 is fixedly installed with the pushing frame 7. The lower end of the pushing frame 7 is rotatably connected to two rollers 11, and the two rollers 11 are arranged in a triangle with the circular rotating frame 1 to ensure the stability of the circular rotating frame 1.

[0028] Specifically, when sowing soybeans, the circular rotating frame 1 is driven to move to the ridge by holding the pushing frame 7 and pushing the rotating cylinder 3. At the same time, the pushing frame 7 is used to drive the supporting frame 10 to move to the water storage tanks on both sides of the ridge by using the rollers 11, so as to support the circular rotating frame 1. At the same time, the water storage tanks on the ridges can limit the movement of the circular rotating frame 1 to ensure that the circular rotating frame 1 can be sown along the ridges. After sowing, the fixing block 15 is pulled by the tension spring 14 to drive the rotating blocks 13 to approach each other, and the rotating blocks 13 drive the U-shaped fixing blocks 12 to move. At the same time, the U-shaped fixing blocks 12 drive the supporting frame 10 to move toward the circular rotating frame 1, thereby reducing the footprint of the sowing device and improving the convenience of storing the sowing device.

[0029] like Figure 1 , Figure 3 and Figure 8As shown, a soil burying assembly is rotatably connected between the support frames 10, and the soil burying assembly includes a V-shaped rotating frame 18 rotatably arranged between the support frames 10, a ground harrow 19 is installed at the lower end of the V-shaped rotating frame 18, and the ground harrow 19 is used to rake the soil on the ridges to bury the sown soybeans.

[0030] like Figure 1 , Figure 3 and Figure 8 As shown, a rotating groove 24 is opened in the lower end of the support frame 10, and a V-shaped rotating frame 18 is located outside the inner cavity of the rotating groove 24 and is fixedly connected to a disc 25. A second torsion spring 26 is fixedly connected to one side of the disc 25, and one end of the second torsion spring 26 is fixedly connected to the inner wall of the rotating groove 24, which is used to twist the V-shaped rotating frame 18 to always fit the ridge of the field, so as to form ridges by raking the soil on both sides of the ridge of the field.

[0031] Specifically, when the circular rotating frame 1 is pushed by the pushing frame 7 to move on the ridge for sowing, the pushing frame 7 is used to drive the supporting frame 10 to move to the water storage tanks on both sides of the ridge by the rollers 11, so as to support the circular rotating frame 1 and ensure the stability of the circular rotating frame 1. Then, in the process of moving the ridge for sowing, the disc 25 is twisted by the second torsion spring 26 to rotate, and the disc 25 drives the V-shaped rotating frame 18 to rotate, so that the V-shaped rotating frame 18 is closely fitted with the ridge. Then, in the process of pushing the circular rotating frame 1 for sowing, the V-shaped rotating frame 18 is tightly fitted with the ridge. The rotating frame 18 can scrape along the surface of the ridge, thereby achieving the effect of scraping the ridge, and at the same time can backfill the pits after sowing, so as to bury the soybean seeds in the pits, which solves the problem that after the existing quantitative sowing device for soybean seeds is completed, the operator still needs to use a shovel to backfill and bury the soybean seeds, which not only affects the soybean sowing efficiency, but also the sowing device rolls on the ridge to sow, which is easy to crush the ridge and cause the irrigation channels on both sides of the ridge to be buried by soil, affecting the subsequent irrigation of the soybean planting field.

[0032] Embodiment 2: Figure 1 , Figure 4 and Figure 5 As shown, the circular rotating frame 1 is annularly fixed with multiple fixed columns 43 on the outside, and the multiple fixed columns 43 are grouped in two and are symmetrically arranged with each other. The second eagle hook cover 42 is rotatably connected between every two fixed columns 43. A transmission groove 48 is opened inside the fixed column 43. The rotating shaft 44 is located outside the inner cavity of the transmission groove 48 and is fixed with a fixed disk 47. A first torsion spring 46 is fixed to one side of the fixed disk 47, and one end of the first torsion spring 46 is fixed to the inner wall of the transmission groove 48.

[0033] like Figure 1 , Figure 2 and Figure 6As shown, a gear ring 2 is installed on one side of the circular rotating frame 1, a toothed disc 61 is installed on one end of the first telescopic frame 62, and the toothed disc 61 is meshed with the gear ring 2. A plurality of balls are evenly arranged on the inner wall of the circular rotating frame 1 to reduce the friction between the circular rotating frame 1 and the rotating cylinder 3.

[0034] Specifically, when the rotating drum 3 is pushed to move by the pushing frame 7, the rotating drum 3 will push the circular rotating frame 1 to rotate, and a plurality of balls are evenly arranged on the inner wall of the circular rotating frame 1, and then when the circular rotating frame 1 is pushed to move by the rotating drum 3, the circular rotating frame 1 will rotate outside the rotating drum 3, and reduce the friction with the rotating drum 3 by using the balls, and the circular rotating frame 1 will also drive the gear ring 2 to rotate synchronously during the rotation process, and at the same time, the gear ring 2 engages the transmission gear plate 61 to rotate, thereby driving the first telescopic frame 62 and the second telescopic frame 63 to rotate to receive the soybean seeds, and then after the first telescopic frame 62 and the second telescopic frame 63 rotate to the discharge port 23, The soybean seeds in the inner cavity of the first telescopic frame 62 and the second telescopic frame 63 will fall into the inner cavity of the discharge port 23, and then fall into the inner cavity of the first eagle hook cover 41 and the second eagle hook cover 42, and then the soybean seeds are discharged into the holes of the field ridges through the first eagle hook cover 41 and the second eagle hook cover 42 for sowing, thereby solving the problem that when sowing soybeans, the existing quantitative sowing device for soybean planting is difficult to use when sowing soybeans in small farmlands or mountainous farmlands due to the large size of the sowing machine, and most of the smaller sowing devices have a simple structure and a single function, and cannot effectively control the sowing amount of soybeans evenly, resulting in excessive discharge of soybeans affecting the yield of soybeans in the later period.

[0035] like Figure 1 , Figure 6 and Fig. 9 As shown, a threaded rod 66 is rotatably connected to the inner cavity of the first telescopic frame 62, one end of the threaded rod 66 is threadedly connected to the second telescopic frame 63, one end of the second telescopic frame 63 is fixedly connected to a plurality of telescopic baffles 65, one end of the threaded rod 66 is fixedly connected to a knob 64, and the threaded rod 66 is used to threadably drive the second telescopic frame 63 to slide outside the first telescopic frame 62 to adjust the size of the inner cavity space of the first telescopic frame 62 and the second telescopic frame 63, so as to control the number of soybean seeds received.

[0036] like Figure 4 , Figure 5 and Fig. 9 As shown, a plurality of feed openings 23 are evenly formed on the inner wall of the circular rotating frame 1 , and each feed opening 23 is connected to the inner cavity of the first eagle hook cover 41 and the second eagle hook cover 42 .

[0037] Specifically, when it is necessary to adjust the number of soybean sowings, the threaded rod 66 is driven to rotate by twisting the knob 64, and the threaded rod 66 is threadedly driven to transmit the second telescopic frame 63, and the second telescopic frame 63 is slid outside the first telescopic frame 62, and at the same time, the second telescopic frame 63 drives the telescopic baffle 65 to move toward the first telescopic frame 62, so as to adjust the distance between the first telescopic frame 62 and the second telescopic frame 63, thereby reducing the inner cavity space of the first telescopic frame 62 and the second telescopic frame 63, and at the same time, the telescopic baffle 65 blocks the discharge port of the guide frame 20, so as to control the number of soybean seeds received by the inner cavity of the first telescopic frame 62 and the second telescopic frame 63, thereby realizing the quantitative discharge and sowing of soybean seeds, solving the problem that the existing quantitative sowing device for soybean planting needs to replace different feeding rollers when it is necessary to control the discharge and sowing number of soybean seeds. If the feeding roller is forgotten or lost, the entire sowing device will be unable to adjust the sowing number of soybean seeds, which is not only cumbersome to use but also very troublesome to carry a large number of accessories of the sowing device.

[0038] Working principle: when sowing soybeans, the soybean seeds are put into the storage box 5 for storage, and then the pushing frame 7 is used to push the rotating cylinder 3 to move, so that the rotating cylinder 3 drives the circular rotating frame 1 to rotate, and during the rotation of the circular rotating frame 1, it will drive the sowing assembly composed of the first eagle hook cover 41 and the second eagle hook cover 42 to rotate synchronously, and then the sowing assembly composed of the first eagle hook cover 41 and the second eagle hook cover 42 can be used to chisel a sowing hole on the ridge during the rotation of the circular rotating frame 1, and during the rotation of the circular rotating frame 1, it will also drive the first telescopic frame 62 to rotate, and then drive the second telescopic frame 63 to rotate, and during the rotation of the first telescopic frame 62 and the second telescopic frame 63, the soybean seeds discharged into the inner cavity of the rotating cylinder 3 in the storage box 5 will be received, and at the same time, during the rotation of the first telescopic frame 62 and the second telescopic frame 63, the soybean seeds will be discharged into the first telescopic frame 62 and the second telescopic frame 63. In the sowing assembly composed of the hook cover 41 and the second eagle hook cover 42, the circular rotating frame 1 will also drive the rotating shaft 44 to rotate synchronously during the rotation of the circular rotating frame 1, and the rotating shaft 44 will drive the rotating rod 45 to rotate, so that the rotating rod 45 will abut against the second telescopic frame 63 during the rotation of the circular rotating frame 1, and then as the circular rotating frame 1 rotates, the rotating rod 45 will drive the rotating shaft 44 to rotate, and the rotating shaft 44 will drive the second eagle hook cover 42 to flip, so as to open the soil in the holes chiseled on the ridges, and at the same time, discharge the soybean seeds into the holes for sowing. When it is necessary to control the quantitative sowing of soybean seeds, the second telescopic frame 63 is driven to slide outside the first telescopic frame 62, and then the distance between the first telescopic frame 62 and the second telescopic frame 63 is adjusted, so as to control the number of soybean seeds received between the first telescopic frame 62 and the second telescopic frame 63, so as to achieve quantitative sowing of soybeans. When the circular rotating frame 1 is pushed by the pushing frame 7 to move on the ridge for sowing, the pushing frame 7 is used to drive the supporting frame 10 to move into the water storage tanks on both sides of the ridge by the rollers 11, so as to support the circular rotating frame 1 and ensure the stability of the circular rotating frame 1. Then, in the process of moving the ridge for sowing, the disc 25 is rotated by the second torsion spring 26, and the disc 25 drives the V-shaped rotating frame 18 to rotate, so that the V-shaped rotating frame 18 is closely fitted with the ridge. Then, in the process of pushing the circular rotating frame 1 for moving sowing, the V-shaped rotating frame 18 can scrape along the surface of the ridge, so as to achieve the effect of scraping the ridge, and at the same time, the pits after sowing can be backfilled with soil, so as to bury the soybean seeds in the pits. When it is necessary to adjust the number of soybeans to be sown, the threaded rod 66 is driven to rotate by twisting the knob 64, and the threaded rod 66 is threadedly driven to transmit the second telescopic frame 63, and the second telescopic frame 63 is made to slide outside the first telescopic frame 62, and at the same time, the second telescopic frame 63 drives the telescopic baffle 65 to move toward the first telescopic frame 62, so as to adjust the distance between the first telescopic frame 62 and the second telescopic frame 63, thereby reducing the inner cavity space of the first telescopic frame 62 and the second telescopic frame 63, and at the same time, the telescopic baffle 65 blocks the discharge port of the guide frame 20, so as to control the number of soybean seeds received by the inner cavity of the first telescopic frame 62 and the second telescopic frame 63, thereby realizing the quantitative discharge and sowing of soybean seeds.
