DETAILED DESCRIPTION

[0028] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0029] Embodiment one: reference Figures 1-9 A ridging seeder, comprising: a mounting frame 1, a sliding block 2, a rotating shaft 3, a mounting frame two 4, a soil turning plate 5, and a spacing adjusting part 6, a plurality of mounting frames 1 are connected at the bottom of the rack 48, the output end of the seeding part 49 connected on the rack 48 is arranged towards the mounting frame 1, a plurality of guide wheels 50 are connected at the bottom of the rack 48, two sliding blocks 2 are slidingly connected on the mounting frame 1, the sliding blocks 2 are connected with the mounting frame two 4 through the rotating shaft 3, the soil turning plate 5 is connected at the bottom of the mounting frame two 4, and the two sliding blocks 2 are connected through the spacing adjusting part 6 on the mounting frame 1.

[0030] The principle of the above scheme is:

[0031] The seeding part 49 has been disclosed by the seeder in the application number CN202110760297.1 of a straw crushing, seeding and fertilizer stirring integrated device in the prior art, the rack 48 is connected at the rear of the agricultural machine, the seeding part 49 moves synchronously with the mounting frame 1 under the guidance of the guide wheel 50 after the agricultural machine is started, when it is necessary to form ridges, the spacing between the two adjacent soil turning plates 5 is adjusted according to the actual requirement of forming ridges, so that the soil turning plate 5 can turn over the soil while the agricultural machine moves forward, and the turned over soil is used to form a ridge table by itself, when the spacing adjusting part 6 adjusts the spacing between the two soil turning plates 5, the sliding block 2 slides relative to the mounting frame 1, and the rotating shaft 3, the mounting frame two 4 and the soil turning plate 5 slide synchronously to control the increase or decrease of the spacing between the two soil turning plates 5.

[0032] The beneficial effects of the above scheme are:

[0033] The device controls the distance between the two soil-turning plates 5 by the distance adjusting piece 6, controls the width of the ridge according to the actual requirement, and makes the device make ridges with different widths to adapt to the required ridge width when different types of seeds are sown, so that the degree of automation is greatly improved.

[0034] The setting of the distance adjusting piece 6 can ensure that the distance between the two soil-turning plates 5 remains stable during the ridge forming stage before sowing, and further ensure that the quality of the ridge meets the requirements of sowing.

[0035] The stable position of the soil-turning plate 5 during sowing can also improve the standardization operation ability of the seeding machine.

[0036] Embodiment two: refer to Figures 1-9 The distance adjusting piece 6 comprises a double screw 7 and a gear 8, the double screw 7 is rotatably connected to the mounting frame 1, two sliding blocks 2 are threadedly connected to the double screw 7, two gears 8 are connected to the middle part of the double screw 7, and the gears 8 are arranged towards the power piece.

[0037] The principle and beneficial effects of the above scheme are:

[0038] When it is required to control the increase of the distance between the two soil-turning plates 5, the double screw 7 is rotated to drive the distance between the two sliding blocks 2 connected therewith to increase; when it is required to control the decrease of the distance between the two soil-turning plates 5, the double screw 7 is rotated to drive the distance between the two sliding blocks 2 connected therewith to decrease, the meshing connection of the double screw 7 and the sliding block 2 not only reduces the complexity of the device, but also can lock the two sliding blocks 2 after adjusting the distance by using the threaded connection, and the sliding connection of the sliding block 2 and the mounting frame 1 improves the smoothness of the sliding block 2 during movement;

[0039] The gear 8 arranged on the double screw 7 is arranged towards the power piece, and when it is required to control the rotation of the double screw 7, only the rotation of the gear 8 controlled by the power piece is required.

[0040] Embodiment three: refer to Figures 1-9 The motor 9 output end on the mounting frame two 4 is connected with the gear two 10, the gear two 10 is meshingly connected with the gear three 11 and the gear four 12 through the gear three 11, the gear three 11 is rotatably connected with the mounting frame two 4, the gear four 12 is connected with the top of the soil-turning plate 5, the mounting frame two 4 is connected with the shaft two 13, the shaft two 13 is rotatably connected with the top of the soil-turning plate 5, and the gear four 12 is coaxially arranged with the shaft two 13.

[0041] The principle and beneficial effects of the above scheme are:

[0042] The required ridges for different kinds of seeds when sowing not only have different widths, but also have different widths between the bottom and the top to adapt to the needs of different crop root growth. When the motor 9 is started during use, the gear two 10 rotates to drive the gear three 11 to rotate. Under the cooperation of the rotating shaft two 13 and the top of the soil turning plate 5, the gear three 11 drives the gear four 12 to rotate, thereby realizing the rotation of the top of the soil turning plate 5. The distance between the bottoms of the two soil turning plates 5 is increased, thereby making the bottom of the ridge wider before sowing;

[0043] The reverse rotation of the gear two 10 drives the gear three 11 to rotate. Under the cooperation of the rotating shaft two 13 and the top of the soil turning plate 5, the gear three 11 drives the gear four 12 to reverse rotation, thereby realizing the reverse rotation of the top of the soil turning plate 5. The distance between the bottoms of the two soil turning plates 5 is reduced, thereby making the bottom of the ridge narrower before sowing. The mechanism further utilizes the internal space of the device to realize more functions, not only simplifying the structure of the device, but also reducing the difficulty of manufacturing the device;

[0044] The center of the gear four 12 connected to the top of the soil turning plate 5 is coaxially arranged with the rotating shaft two 13, which can directly control the rotation of the top of the soil turning plate 5 through the rotation of the gear four 12, preventing mechanical interference and improving the efficiency of the device during work.

[0045] Embodiment four: reference Figures 1-9 Further comprising: a rotating mechanism 14, the rotating mechanism 14 comprising: a bevel gear 15 and a bevel gear two 16, one bevel gear 15 is connected to the top of each rotating shaft 3, the bevel gear 15 is meshed and connected with the bevel gear two 16, the rotating shaft 3 is rotationally connected with the sliding block 2, the bevel gear two 16 is connected with the drive pipe 17, and the drive pipe 17 is rotationally connected with the sliding block 2.

[0046] The principle and advantages of the above scheme are:

[0047] During the forward movement of the agricultural machine, when breaking up the soil clumps or cutting off the roots of weeds during plowing, the included angle between the front end inner wall of the soil turning plate 5 and the direction of travel of the seeding machine is increased. When reducing the disturbance of the soil turning plate 5 to the soil during sowing and ensuring the moisture content of the soil in the sowing state, the included angle between the front end inner wall of the soil turning plate 5 and the direction of travel of the seeding machine is reduced.

[0048] The forward rotation of the drive pipe 17 drives the bevel gear two 16 to rotate, which in turn drives the bevel gear 15 connected thereto to rotate. The bevel gear 15 drives the rotating shaft 3 to rotate on the sliding block 2, thereby increasing the included angle between the front end inner wall of the soil turning plate 5 and the direction of travel of the seeding machine.

[0049] The reverse rotation of the driving pipe 17 drives the reverse rotation of the bevel gear 16, the reverse rotation of the bevel gear 16 drives the reverse rotation of the bevel gear 15 connected with the bevel gear 16, the reverse rotation of the bevel gear 15 drives the reverse rotation of the rotating shaft 3 on the sliding block 2, thereby reducing the included angle between the inner wall of the front end of the soil turning plate 5 and the advancing direction of the seeding machine, and further improving the adaptability of the device to different working conditions and working requirements during operation.

[0050] Embodiment five: Figures 1-9 The power member comprises an inner pipe 18, a bevel gear 19, a bevel gear 20, a driving motor 21 and an auxiliary driving member 22, the inner pipe 18 is slidably connected with two driving pipes 17, the inner pipe 18 is rotatably connected with the mounting frame 1, the driving pipe 17 is connected with the inner pipe 18 through a locking mechanism 23, the bevel gear 19 connected with the end of the inner pipe 18 is in meshing connection with the bevel gear 20, the bevel gear 20 is connected with the output end of the driving motor 21, the driving motor 21 is connected with the mounting frame 1, and the auxiliary driving member 22 on the inner pipe 18 is arranged towards the gear 8.

[0051] The principles and advantages of the above-mentioned scheme are:

[0052] The inner pipe 18 is rotatably connected with the mounting frame 1, and the driving pipe 17 is slidably connected with the inner pipe 18, when it is needed to rotate the inner pipe 18, the driving motor 21 is started, the bevel gear 20 rotates in the positive direction to drive the bevel gear 19 connected with the bevel gear 20 to rotate in the positive direction, and the inner pipe 18 rotates in the positive direction at the same time.

[0053] When it is needed to rotate the inner pipe 18 in the reverse direction, the driving motor 21 is started, the bevel gear 20 rotates in the reverse direction to drive the bevel gear 19 connected with the bevel gear 20 to rotate again, and the inner pipe 18 rotates in the reverse direction at the same time, since the driving pipe 17 is slidably connected with the inner pipe 18, the inner pipe 18 can still control the driving pipe 17 to rotate through the locking mechanism 23 after the spacing between the two sliding blocks 2 is adjusted, therefore, when the included angle between the two soil turning plates 5 is adjusted, the spacing between the two soil turning plates 5 can be adjusted before or after the included angle is adjusted according to the habit of the operator or the state of the device during operation, thereby improving the flexibility of the device during use.

[0054] Meanwhile, the auxiliary driving member 22 is arranged towards the gear 8, whether the auxiliary driving member 22 is connected with the gear 8 or not can be selected, thereby transmitting the rotation of the inner pipe 18 to the gear 8 to control the rotation of the double screw 7.

[0056] The principle and beneficial effects of the above scheme are:

[0057] After the two moving rings 30 move away from each other, the inclined surface two 31 of the moving ring 30 exerts pressure on the inclined surface 25, and then under the plug-in cooperation of the locking rod 28 and the through hole 27, the pressing plate 24 moves towards the axis of the inner tube 18, and the plug-in cooperation of the locking rod 28 and the locking hole 29 ends, at this time, after the driving motor 21 is started, the forward rotation and reverse rotation of the inner tube 18 will not affect the rotation of the driving tube 17, and at this time, the soil turning plate 5 will not rotate;

[0058] After the two moving rings 30 move close to each other, the pressure exerted by the inclined surface two 31 of the moving ring 30 on the inclined surface 25 stops, and then under the plug-in cooperation of the locking rod 28 and the through hole 27, the pressing plate 24 moves away from the axis of the inner tube 18, and the plug-in cooperation of the locking rod 28 and the locking hole 29 begins, at this time, after the driving motor 21 is started, the forward rotation and reverse rotation of the inner tube 18 can drive the forward rotation or reverse rotation of the driving tube 17, and at this time, the soil turning plate 5 can rotate to adjust the angle;

[0059] The mechanism controls whether the locking rod 28 and the locking hole 29 are in plug-in cooperation, and then controls whether the inner tube 18 and the driving tube 17 rotate synchronously, not only fully utilizes the space inside the device, but also places the synchronous rotation components inside the inner tube 18, avoiding direct contact with the external environment, thereby avoiding the contact between foreign matters such as soil dust or weeds and the mechanism, preventing the device from being jammed or damaged, and improving the safety of the device during work;

[0060] The locking holes 29 are arranged in a straight line on the inner wall of the driving pipe 17, and the locking holes 29 arranged in a straight line form a transverse locking area, and the circular array arranged on the inner wall of the driving pipe 17 can avoid that the locking rod 28 cannot be inserted and matched with the locking hole 29 after rotation, thereby avoiding that the driving pipe 17 cannot rotate synchronously with the inner pipe 18.

[0062] The principle and beneficial effects of the above scheme are:

[0063] When the moving ring 30 is not subjected to an external force, the limiting gear 35 connected with the torsional spring 34 is fixed, and then the rack 32 and the mounting shaft 33 are fixed in the inner pipe 18, when the two moving rings 30 are close to each other, under the cooperation of the mounting shaft 33 and the inner pipe 18, the rack 32 drives the limiting gear 35 meshingly connected thereto to rotate, and the torsional spring 34 is twisted to store energy; when the two moving rings 30 are away from each other, under the cooperation of the mounting shaft 33 and the inner pipe 18, the rack 32 drives the limiting gear 35 meshingly connected thereto to rotate in the opposite direction, and the torsional spring 34 resets, and the arrangement of the torsional spring 34 can ensure that the distance between the two moving rings 30 remains unchanged, when the inner pipe 18 is rotating, the driving pipe 17 will not be mistakenly unlocked, thereby ensuring the stability and safety of the two during rotation.

[0064] Embodiment eight: Figures 1-9 The auxiliary driving piece 22 further comprises: a sliding block two 36, a tooth ring 37 and a sliding groove 38, the end of each sliding block two 36 is connected to the side wall of each moving ring 30, the sliding block two 36 is slidingly connected to the sliding groove 38 of the inner pipe 18, the end of the sliding block two 36 outside the inner pipe 18 is connected to the inner wall of the tooth ring 37, the tooth ring 37 is slidingly connected to the inner pipe 18, the annular groove 39 is formed in the end face of the tooth ring 37, the two annular grooves 39 are oppositely arranged, the end of the annular groove two 40 is connected to the inner wall of the annular groove 39, the cross section of the annular groove two 40 is spherical, the annular groove two 40 is slidingly connected to the ball head 41, the ball head 41 is connected to the end of the rod body 42, the rod body 42 is slidingly connected to the annular groove 39, and the end of the rod body 42 away from the tooth ring 37 is connected to the end of the shaft coupling 43.

[0066] The principle and beneficial effects of the above scheme are:

[0067] When the two moving rings 30 move close to or away from each other, the synchronously moving sliding block two 36 is in sliding cooperation with the sliding groove 38, and the gear ring 37 moves synchronously. When the interval between the two gear rings 37 needs to be adjusted, the interval between the two gear rings 37 is increased, and after each gear ring 37 is meshed and connected with a gear 8 respectively, the movement of the gear ring 37 is stopped. Subsequently, the start of the driving motor 21 can drive the inner tube 18 to move, and then drive the double screw 7 to rotate under the meshing connection of the gear ring 37 and the gear 8, so as to realize the adjustment of the interval between the two sliding blocks 2. At the same time, the plug-in cooperation of the locking rod 28 and the locking hole 29 is ended, the rotation of the driving tube 17 is stopped, the synchronous adjustment of the interval and the angle of the soil turning plate 5 is avoided, and the accuracy of the soil turning plate 5 during adjustment is improved.

[0068] While the double screw 7 rotates, the limiting tube 51 moves synchronously, the chamfer on the limiting tube 51 is in contact with the chamfer two 53, the longitudinal sliding block 52 moves towards the driving tube 17, and the length of the limiting spring 54 is elongated. At this time, the bottom of the longitudinal sliding block 52 is in contact with the side wall of the driving tube 17, further increasing the stability of the driving tube 17, preventing the driving tube 17 from rotating due to vibration or other external forces while the double screw 7 rotates.

[0069] At the same time, the rotating gear ring 37 can drive the limiting tube 51 to rotate, the chamfer two 53 and the chamfer slide at this time, and the longitudinal sliding block 52 will not be reset;

[0070] After the interval adjustment between the two sliding blocks 2 is completed, the interval between the two gear rings 37 is reduced, the gear ring 37 ends the meshing connection with the gear 8, the synchronous contact cooperation of the chamfer two 53 and the chamfer ends, and the bottom of the longitudinal sliding block 52 ends the contact cooperation with the side wall of the driving tube 17 under the elastic force of the limiting spring 54. At the same time, the plug-in cooperation of the locking rod 28 and the locking hole 29 can make the driving tube 17 and the inner tube 18 rotate synchronously.

[0071] Example nine: reference Figures 1-9The other end of the shaft coupling 43 is connected with the bottom end of the push rod 44, the top end of the two push rods 44 is hinged with the output end of the electric push rod 45, the top end of the electric push rod 45 is vertically connected on the mounting frame 1, and the tooth ring 37 is arranged between the two gear wheels 8, and the side wall of the tooth ring 37 is arranged towards the side wall of the gear wheel 8.

[0072] The principle and beneficial effects of the above scheme are:

[0073] The spacing between the two tooth rings 37 can be adjusted by the electric push rod 45, after the output end of the electric push rod 45 moves downward, the spacing between the bottom of the two push rods 44 increases, the push rod 44 drives the shaft coupling 43 to move, the spacing between the two shaft couplings 43 increases, the synchronous ball head 41 and the rod body 42 move, and then the spacing adjustment of the tooth ring 37 is realized;

[0074] After the output end of the electric push rod 45 moves upward, the spacing between the bottom of the two push rods 44 decreases, the push rod 44 drives the shaft coupling 43 to move reversely, the spacing between the two shaft couplings 43 decreases, the synchronous ball head 41 and the rod body 42 move reversely, and then the reverse spacing adjustment of the tooth ring 37 is realized.

[0075] When the tooth ring 37 rotates, the rod body 42 is slidably connected with the annular groove 39, and the annular groove two 40 is slidably connected with the ball head 41, so that the arrangement of the annular groove 39 and the annular groove two 40 can not only ensure that the tooth ring 37 moves smoothly on the inner tube 18, but also will not block the rotation of the tooth ring 37.
