Description

Technical Field

[0001] The invention relates to the technical field of rice hole seeding, and in particular to a multifunctional rice hole seeding integrated machine and a hole seeding method. Background Art

[0002] There are two ways of planting rice: dry planting and transplanting. The existing fertilizing device is located behind the furrowing device to spread the fertilizer into the furrows opened by the furrowing device, and the sowing device is located behind the fertilizing device to spread the seeds and fertilizer at the same position, and the soil covering device is used to fill the furrows opened by the furrowing device and cover the seeds with soil to complete the dry planting of rice. However, this method usually has the following problems: First, the process of sowing seeds is usually carried out on soft soil, but the cultivated land is usually uneven. Conventional furrow sowing uses mechanized equipment, which will cause the sown rice grains to be on the same level underground, but the heights of these rice grains from breaking through the soil are different. The reason for this is usually that the hole depths are different during the hole sowing process, causing some rice grains to be buried too deep, thereby reducing the germination rate; Secondly, the regulation of the sowing interval is difficult to carry out with existing devices, and rapid regulation is not possible.

[0003] Therefore, we have designed a multifunctional rice hole-seeding machine and a hole-seeding method. Summary of the invention

[0014] The specific operation steps of the rice multifunctional hole sowing machine are as follows: S1: In the initial state, the hand push rod is located in the middle of the positioning slide hole on the toggle plate. The operator pushes the hand push rod to drive the device forward in the cultivated land. Due to the different heights of the cultivated land, the second roller is close to the ground. When the sowing ground is convex or concave, the second roller drives the piston on the second roller to rise and fall in the second bottom cylinder, and then drives the position of the bottom block under the L-shaped rod to change, thereby adjusting the descending height of the top plate to ensure that the penetration depth of the soil-breaking cone assembly is consistent; S2: The first drive motor and the second drive motor drive the forward screw and the reverse screw to rotate, and the top plate touches the top block and the bottom block, which will drive the second lifting block to change its position in the inner cavity, and then push the first telescopic plug rod or the second telescopic plug rod out to abut against the forward screw or the reverse screw, thereby ensuring that the lifting direction of the groundbreaking cone assembly is regulated when the first telescopic plug rod or the second telescopic plug rod is switched to extend; S3: When the top disk with the soil-breaking cone assembly descends to the lowest end, the bottom block pushes the second lifting block to rise, and then the first wire is connected to the first connection contact group and triggers the electric push rod to retract, and then the multiple arc cone plates are opened, which can not only expand the pierced soil, but also scatter the rice grains transferred into the soil-breaking cone assembly into the pit. When the soil-breaking cone assembly is lifted, the second lifting block falls under the action of gravity and reconnects the first wire with the second connection contact group, allowing the electric push rod to extend and drive the arc cone plate to close. When the top disk with the soil-breaking cone assembly is lifted, the puncture frame at the bottom of the top membrane-breaking assembly will collapse the rubber baffle to allow the rice grains to fall into the lower pressure cylinder. When the top disk falls, the puncture frame leaves the rubber baffle and prevents the rice grains from falling continuously; S4: When the sowing interval needs to be adjusted, it is only necessary to swing the angle of the toggle plate and then position it with bolts. This will drive the rotation of the rotating shaft in the rice storage box body, thereby driving the position of the current sensor to change, and then driving the position of the second lever on the sliding rheostat, so the current also changes. The current sensor transmits the electrical signal of the current change to the first drive motor and the second drive motor, and then changes the rotation speed of the first drive motor and the second drive motor, and finally completes the change of the lifting frequency of the soil-breaking cone assembly.

[0015] The beneficial effects of the present invention are: 1. In the present invention, due to the different heights of cultivated land, the second roller is close to the ground. When the sowing ground is convex or concave, the second roller drives the piston on the second roller to rise and fall in the second bottom cylinder, and then drives the bottom stopper under the L-shaped rod to change its position, thereby regulating the descending height of the top plate to ensure that the penetration depth of the soil-breaking cone assembly is consistent.

[0016] 2. The present invention adopts that when the top disk is lifted with the soil-breaking cone assembly, the puncturing frame at the bottom of the top membrane-breaking assembly will collapse the rubber baffle to allow the rice grains to fall into the downward pressure cylinder, that is, during the lifting process of the top disk, it first touches the puncturing frame at the bottom of the top membrane-breaking assembly to complete the replenishment of the rice grains, and then the second lifting block is pushed down under the action of the top baffle and the movement direction is changed again. At this time, when the top disk falls, the puncturing frame leaves the rubber baffle and prevents the rice grains from continuing to fall, thereby completing the replenishment of the rice grains.

DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 11 The multifunctional rice hole-seeding machine comprises a rice storage box body 1 and a current sensor 13 arranged in the rice storage box body 1. A rotating shaft 3 runs through the rice storage box body 1, wherein first rollers 4 are arranged at both ends of the rotating shaft 3 for moving on cultivated land.

[0020] A hand push rod 5 is provided on the rice storage box body 1, and a toggle plate 6 connected to the rotating shaft 3 is provided on the hand push rod 5, and a positioning slide hole 2 for positioning is provided on the toggle plate 6. The hand push rod 5 slides in the positioning slide hole 2, and a bolt that abuts against the hand push rod 5 is provided in the positioning slide hole 2. When the sowing interval needs to be adjusted, it is only necessary to adjust the position of the toggle plate 6 on the hand push rod 5 and then lock it with the bolt.

[0021] A thread groove 12 is provided on the outer wall of the rotating shaft 3 in the rice storage box body 1, a sliding rheostat 16 is also provided in the rice storage box body 1, a current sensor 13 slides on the inner wall of the rice storage box body 1, a first push rod 14 abutting against the thread groove 12 is fixed on the current sensor 13, a second push rod 15 abutting against the sliding rheostat 16 is provided at the bottom of the first push rod 14, a first drive motor 17 and a second drive motor 18 are also provided in the rice storage box body 1, the current sensor 13, the sliding rheostat 16, the first drive motor 17 and the second drive motor 18 are connected in series through wires, so that the setting only needs to swing the angle of the toggle plate 6, and then use bolts to position it, which will drive the rotating shaft 3 rotates in the rice storage box body 1, thereby driving the position of the current sensor 13 to change, and then driving the position of the second push rod 15 on the sliding rheostat 16, so the current also changes, and the current sensor 13 transmits the electric signal of the current change to the first drive motor 17 and the second drive motor 18, and then changes the rotation speed of the first drive motor 17 and the second drive motor 18, and finally completes the change of the lifting frequency of the soil-breaking cone assembly 8, and the current sensor 13 feeds back the current size to the first drive motor 17 and the second drive motor 18 through the electric signal, and changes the rotation speed of the first drive motor 17 and the second drive motor 18, which is the prior art and will not be elaborated on here.

[0022] A linearly fixed first bottom tube 7 is provided at the bottom of the rice storage box body 1, a top plate 22 is provided inside the first bottom tube 7, and two side grooves 26 are symmetrically provided on the inner wall of the first bottom tube 7. The top plate 22 is lifted and slid in the side grooves 26 through the side blocks 27. At the same time, a lower pressure tube 21 is coaxially fixed to the top plate 22, and a soil-breaking cone assembly 8 is arranged on the lower pressure tube 21, so that the lifting and lowering of the top plate 22 drives the soil-breaking cone assembly 8 below to lift and lower together, thereby completing the penetration effect into the cultivated land.

[0023] Reference Figure 4 and Figure 6state, a detection roller part for adjusting the penetration depth of the soil-breaking cone assembly 8 is also provided at the bottom of the rice storage box body 1, and the detection roller part includes a second bottom tube 9, the second bottom tube 9 is fixed at the bottom of the rice storage box body 1, a roller rod 10 is provided in the second bottom tube 9, and second rollers 11 and pistons are provided at both ends of the roller rod 10, and the roller rod 10 is lifted and slid in the second bottom tube 9 through the piston and the return spring, so that when the second roller 11 is against the ground, the ground state can be fed back; That is, due to the different heights of the cultivated land, the second roller 11 is close to the ground. When the sowing ground is convex or concave, the second roller 11 drives the piston on the second roller 11 to rise and fall in the second bottom cylinder 9, and then drives the bottom stopper 35 under the L-shaped rod 28 to change its position, thereby regulating the descending height of the top plate 22, so that the penetration depth of the soil-breaking cone assembly 8 is consistent; The detection roller part also includes side holes 36, which have two side holes 36 and are opened at the opposite ends of the second bottom tube 9 and the first bottom tube 7. An L-shaped rod 28 connected to the piston is arranged in the side hole 36 of the side wall of the first bottom tube 7. A bottom stopper 35 is slidably arranged at the bottom of the L-shaped rod 28, and a chamfer 38 is arranged at the bottom of the bottom stopper 35. The top of the bottom stopper 35 is flat. In this way, during the descending process of the ground-breaking cone assembly 8 and the top plate 22, since the outer side wall of the ground-breaking cone assembly 8 is a curved surface, it will be pressed against the bottom stopper 35 and retracted into the side hole 36 without hindering the movement of the ground-breaking cone assembly 8. When the ground-breaking cone assembly 8 passes over the bottom stopper 35, the bottom stopper 35 re-pops out of the side hole 36 under the action of the internal spring. During the descending process of the top plate 22, the top of the top plate 22 is flat, so the positioning of the top plate 22 can be completed.

[0024] When the top plate 22 is lifted with the ground-breaking cone assembly 8, the chamfer 38 at the bottom of the bottom stopper 35 will press against the ground-breaking cone assembly 8, and then retract into the side hole 36 against the bottom stopper 35. Therefore, the lifting and lowering of the ground-breaking cone assembly 8 will not be affected. The setting of the bottom stopper 35 only serves to position the top plate 22.

[0025] The detection roller portion also includes a top stopper 24, which is fixed to the top inner wall of the first bottom tube 7. Therefore, the movable range of the top disk 22 is between the top stopper 24 and the bottom stopper 35. Due to the different heights of the cultivated land, the second roller 11 is close to the ground. When the sowing ground is convex or concave, the second roller 11 drives the piston on the second roller 11 to rise and fall in the second bottom tube 9, and then drives the bottom stopper 35 under the L-shaped rod 28 to change its position, thereby regulating the descending height of the top disk 22, so that the penetration depth of the soil-breaking cone assembly 8 is consistent, thereby avoiding burying the seeds too deep and affecting the germination rate.

[0026] A forward screw 19 and a reverse screw 20 are respectively provided in the two side grooves 26, and the forward screw 19 and the reverse screw 20 pass through the side blocks 27 on both sides of the top plate 22. The output ends of the first drive motor 17 and the second drive motor 18 are respectively connected to the forward screw 19 and the reverse screw 20. It should be noted that the forward screw 19 and the reverse screw 20 provide power for the lifting and lowering of the top plate 22, that is, when the first telescopic rod 43 or the second telescopic rod 44 in the top plate 22 is switched to counteract the forward screw 19 or the reverse screw 20, it can drive the top plate 22 to rise and fall continuously.

[0027] Reference Figure 8 In this state, a lifting and lowering adjustment part for adjusting the lifting and lowering frequency of the ground-breaking cone assembly 8 is provided in the first bottom tube 7, and the lifting and lowering adjustment part includes an inner cavity 41, which is annular and opened in the top plate 22, and a first pressing hole 39 and a second pressing hole 40 adapted to the top stopper 24 and the bottom stopper 35 are respectively opened at the top and bottom of the top plate 22.

[0028] A second lifting block 42 is provided in the inner cavity 41, and the height of the second lifting block 42 is smaller than the height of the inner cavity 41. The lifting adjustment part also includes a first telescopic rod 43 and a second telescopic rod 44. The first telescopic rod 43 and the second telescopic rod 44 are respectively telescopically slidable on the side wall of the top plate 22. The first telescopic rod 43 and the second telescopic rod 44 are both retracted and retracted by a thin spring. When the top plate 22 descends and hits the lifting plate 45 in the second pressing hole 40, the second lifting block 42 provided in the inner cavity 41 will be lifted, so that the second telescopic plug rod 44 originally pushed out by the second lifting block 42 will retract into the top plate 22 under the action of the thin spring and will no longer hit the reverse screw 20. On the contrary, the first telescopic plug rod 43 originally retracted in the top plate 22 will be pushed out and hit the forward screw 19. This will change the movement trend of the top plate 22 from the original descent to lifting. Since the second lifting block 42 has friction in the inner cavity 41 and overcomes gravity, the second lifting block 42 will not fall. Only under the action of the top stop block 24, the second lifting block 42 is pushed down and the movement direction is changed again. Therefore, when the first telescopic plug rod 43 or the second telescopic plug rod 44 switches to extend, the lifting direction of the ground-breaking cone assembly 8 is regulated.

[0029] A rubber baffle 25 for blocking rice grains is provided on the top of the pressing cylinder 21, a top membrane-breaking assembly 23 is also provided on the inner wall at the top of the first bottom cylinder 7, and a puncturing frame for passing through the rubber baffle 25 and allowing rice grains to fall is provided at the bottom of the top membrane-breaking assembly 23. When the top plate 22 is lifted with the soil-breaking cone assembly 8, the puncturing frame at the bottom of the top membrane-breaking assembly 23 will collapse the rubber baffle 25, allowing the rice grains to fall into the pressing cylinder 21, that is, during the lifting process of the top plate 22, the puncturing frame at the bottom of the top membrane-breaking assembly 23 will first touch the puncturing frame at the bottom of the top membrane-breaking assembly 23 to complete the replenishment of rice grains, and then the second lifting block 42 will be pushed down under the action of the top baffle 24 and the movement direction will be changed again. At this time, when the top plate 22 falls, the puncturing frame leaves the rubber baffle 25 and blocks the rice grains from continuing to fall, thereby completing the replenishment of rice grains.

[0030] A soil-breaking cone assembly 8 for piercing the soil is provided in the first bottom cylinder 7, and the soil-breaking cone assembly 8 includes a plurality of circumferentially arranged arc cone plates, and the arc cone plates rotate on the side wall of the lower pressure cylinder 21 through a hinge 29, and a plurality of circumferentially arranged slide grooves 34 are provided on the side wall of the lower pressure cylinder 21, and a first lifting block 33 slides in the slide groove 34, and the first lifting block 33 is connected to the arc cone plate through a connecting rod 30, and both ends of the connecting rod 30 are rotatably connected to the arc cone plate and the first lifting block 33 through a first sphere 31 and a second sphere 32 respectively.

[0031] Reference Figure 8-Figure 11 State, the first bottom tube 7 is also provided with an expansion part for opening the soil-breaking cone assembly 8 and scattering rice grains into the pit, the expansion part includes a lifting plate 45, the lifting plate 45 is lifted and lowered in the second pressing hole 40, and the bottom of the top plate 22 is provided with a baffle 49 for limiting the lifting plate 45, and the inner walls of the second pressing hole 40 are respectively provided with a first connecting contact group 47 and a second connecting contact group 48, wherein when the top plate 22 descends to the lowest end with the soil-breaking cone assembly 8, the bottom stop block 35 pushes the second lifting block 42 to lift, and then the first wire 46 is connected with the first connecting contact group 47 and triggers the electric push rod 50 to retract.

[0032] A lifting ring 37 is slidingly arranged on the outer wall of the lower pressure cylinder 21, and the output end of the electric push rod 50 is connected to the lifting ring 37. When the top plate 22 descends to the lowest end with the soil-breaking cone assembly 8, the bottom stop block 35 pushes the second lifting block 42 to lift, and then the first wire 46 is connected to the first connecting contact group 47 and triggers the electric push rod 50 to retract, and then a plurality of arc cone plates are opened, which can not only expand the penetrated soil, but also scatter the rice grains transferred into the soil-breaking cone assembly 8 into the pit. When the soil-breaking cone assembly 8 is lifted, the second lifting block 42 falls under the action of gravity and reconnects the first wire 46 with the second connecting contact group 48, allowing the electric push rod 50 to extend, driving the arc cone plate to close, wherein the first wire 46 is connected to the first connecting contact group 47 and triggers the electric push rod 50 to retract, and the first wire 46 is connected to the second connecting contact group 48, allowing the electric push rod 50 to extend is a prior art and will not be elaborated on here.

[0033] The working principle of the present invention is as follows: The specific operation steps of the rice multifunctional hole sowing machine are as follows: S1: In the initial state, the hand push rod 5 is located in the middle of the positioning slide hole 2 on the toggle plate 6. The operator pushes the hand push rod 5 to drive the device to move forward in the cultivated land. Due to the different heights of the cultivated land, the second roller 11 is close to the ground. When the sowing ground is convex or concave, the second roller 11 drives the piston on the second roller 11 to rise and fall in the second bottom tube 9, and then drives the bottom stopper 35 under the L-shaped rod 28 to change its position, thereby regulating the descending height of the top plate 22, so that the penetration depth of the soil-breaking cone assembly 8 is consistent; S2: The first drive motor 17 and the second drive motor 18 drive the forward screw 19 and the reverse screw 20 to rotate, and the top plate 22 touches the top stopper 24 and the bottom stopper 35, which will drive the second lifting block 42 to change its position in the inner cavity 41, and then push the first telescopic plug 43 or the second telescopic plug 44 out to abut against the forward screw 19 or the reverse screw 20, so as to ensure that the lifting direction of the ground-breaking cone assembly 8 is regulated when the first telescopic plug 43 or the second telescopic plug 44 switches to extend; S3: When the top plate 22 with the soil-breaking cone assembly 8 descends to the lowest end, the bottom stopper 35 pushes the second lifting block 42 to rise, and then the first wire 46 is connected with the first connection contact group 47 and triggers the electric push rod 50 to retract, and then the multiple arc cone plates are opened, which can not only expand the pierced soil, but also scatter the rice grains transferred into the soil-breaking cone assembly 8 into the pit. When the soil-breaking cone assembly 8 is lifted, the second lifting block 42 falls under the action of gravity and reconnects the first wire 46 with the second connection contact group 48, allowing the electric push rod 50 to extend and drive the arc cone plate to close. When the top plate 22 with the soil-breaking cone assembly 8 is lifted, the puncture frame at the bottom of the top membrane-breaking assembly 23 will collapse the rubber baffle 25, allowing the rice grains to fall into the lower pressing cylinder 21. When the top plate 22 falls, the puncture frame leaves the rubber baffle 25 and prevents the rice grains from falling continuously. S4: When the sowing interval needs to be adjusted, it is only necessary to swing the angle of the toggle plate 6 and then position it with bolts. This will drive the rotation of the rotating shaft 3 in the rice storage box body 1, thereby driving the position of the current sensor 13 to change, and then driving the position of the second support rod 15 on the sliding rheostat 16, so the current also changes. The current sensor 13 transmits the electrical signal of the current change to the first drive motor 17 and the second drive motor 18, and then changes the rotation speed of the first drive motor 17 and the second drive motor 18, and finally completes the change of the lifting frequency of the soil-breaking cone assembly 8.

10. A rice hole sowing method using a multifunctional rice hole sowing machine, using the multifunctional rice hole sowing machine of claim 9, characterized in that: The specific steps are as follows: S1: In the initial state, the hand push rod (5) is located in the middle position of the positioning slide hole (2) on the toggle plate (6). The operator pushes the hand push rod (5) to drive the device to move forward on the cultivated land. Due to the different heights of the cultivated land, the second roller (11) is in contact with the ground. When the sowing ground is convex or concave, the second roller (11) drives the piston on the second roller (11) to rise and fall in the second bottom cylinder (9), and then drives the bottom stopper (35) under the L-shaped rod (28) to change its position, thereby regulating the descending height of the top plate (22) so that the penetration depth of the soil-breaking cone assembly (8) is consistent; S2: The first drive motor (17) and the second drive motor (18) drive the forward screw (19) and the reverse screw (20) to rotate, and the top plate (22) touches the top stopper (24) and the bottom stopper (35), which drives the second lifting block (42) to change its position in the inner cavity (41), and then the first telescopic plug (43) or the second telescopic plug (44) is pushed out to abut against the forward screw (19) or the reverse screw (20), thereby ensuring that the lifting direction of the ground-breaking cone assembly (8) is regulated when the first telescopic plug (43) or the second telescopic plug (44) is switched to extend; S3: When the top plate (22) with the soil-breaking cone assembly (8) descends to the lowest end, the bottom stopper (35) pushes the second lifting block (42) to rise, and then the first wire (46) is connected to the first connection contact group (47) and triggers the electric push rod (50) to retract, and then the multiple arc cone plates are opened, which can not only expand the penetrated soil, but also scatter the rice grains transferred into the soil-breaking cone assembly (8) into the pit. When the soil-breaking cone assembly (8) is lifted, the second lifting block (42) is lifted. The block (42) falls under the action of gravity and reconnects the first wire (46) with the second connection contact group (48), allowing the electric push rod (50) to extend, driving the arc cone plate to close. When the top plate (22) is lifted with the soil-breaking cone assembly (8), the puncturing frame at the bottom of the top membrane-breaking assembly (23) will collapse the rubber baffle (25), allowing the rice grains to fall into the lower pressing cylinder (21). When the top plate (22) falls, the puncturing frame leaves the rubber baffle (25) and prevents the rice grains from continuing to fall. S4: When it is necessary to adjust the sowing interval, it is only necessary to swing the angle of the toggle plate (6) and then position it with a bolt. This will drive the rotation of the rotating shaft (3) in the rice storage box body (1), thereby driving the position of the current sensor (13) to change, and then driving the position of the second support rod (15) on the sliding rheostat (16), so that the current also changes. The current sensor (13) transmits the electrical signal of the change in current to the first drive motor (17) and the second drive motor (18), and then changes the rotation speed of the first drive motor (17) and the second drive motor (18), and finally completes the change of the lifting and lowering frequency of the soil-breaking cone assembly (8).
