Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Refer to Figures 1 - 15 , a satellite radar ground wheel speed measurement non-equidistant intelligent control electric seeder, including a body 1, the body 1 includes wheels with brake discs and a front bumper; a satellite radar ground wheel speed measurement component is installed on the body 1, and the satellite radar ground wheel speed measurement includes a Beidou satellite locator, a millimeter wave radar speedometer, a ground wheel speedometer, and a Kalman filter; a Beidou satellite locator and a Kalman filter are installed on the body 1, a ground wheel speedometer is installed on the brake disc, and a millimeter wave radar speedometer is installed on the front bumper; the Beidou satellite locator provides accurate positioning information, the millimeter wave radar speedometer is used for accurate speed measurement during seeding work, the ground wheel speedometer accurately measures the moving speed based on the speed of the wheel rotation, and the Kalman filter performs weighted fusion on the data from the Beidou satellite locator, the millimeter wave radar speedometer, and the ground wheel speedometer to provide an optimal speed estimate; the satellite radar ground wheel speed measurement component also includes a control system and an intelligent decision-making module, the control system and the intelligent decision-making module are set on the body 1, and the control system and the intelligent decision-making module are used to coordinate the work of the Beidou satellite locator, the millimeter wave radar speedometer, the ground wheel speedometer, and the Kalman filter, such as a PID controller; a control panel can also be installed on the body 1, which has the function of displaying the real-time working state and historical data.

[0020] Refer to Figures 1 - 15, a placing table 2 and a support frame 7 are fixedly installed on the body 1. A seed box 3 is fixedly installed on the placing table 2. A pipe 1 4 is fixedly communicated with the support frame 7. A plurality of pipes 2 5 are slidably communicated with the support frame 7. A distance adjusting member matched with the plurality of pipes 1 4 is installed on the support frame 7; the distance adjusting member includes a support block, a reciprocating screw assembly 8, a power assembly, and a moving assembly. Two support blocks (not labeled in the figure) are symmetrically and fixedly installed on the upper surface of the support frame 7. A reciprocating screw assembly 8 is rotatably installed on each of the two support blocks. The reciprocating screw assembly 8 is fixedly composed of two reciprocating screws 3. And the pitch of the reciprocating screw 3 close to the pipe 1 4 is greater than the pitch of the reciprocating screw 3 far from the pipe 1 4. As shown in the figure, two pipes 2 5 are arranged on each side of the pipe 1 4. And through the setting of the pitch, when the pipes 2 5 on both sides move, they have the effect of synchronous distance adjustment. For example, the moving amplitude of the pipe 2 5 close to the pipe 1 4 is half of the moving amplitude of the pipe 2 5 far from the pipe 1 4. It is also possible to set the ratio of the pitches to be non-uniform, so that the moving amplitude of the pipe 2 5 close to the pipe 1 4 is not half of the moving amplitude of the pipe 2 5 far from the pipe 1 4. Specifically, it can be set according to the requirements to better meet the usage requirements. When specifically setting the number of the pipes 2 5, it can be set according to the sowing scale. For example, three are arranged on each side.

[0021] The pipes 2 5 are symmetrically arranged on both sides of the pipe 1 4 respectively, and are installed on the corresponding reciprocating screw assemblies 8 through the moving assembly. The moving assembly includes a moving seat 1 13, a cross block 14, a ball nut 1, and a sliding hole 15. A moving seat 1 13 is installed on each of the reciprocating screws 3 through the ball nut 1. Two cross blocks 14 are fixedly installed on each of the pipes 1 4. And the cross blocks 14 are respectively located on the upper and lower sides of the support frame 7. And the cross block 14 located above is fixedly arranged with the corresponding moving seat 1 13; a plurality of sliding holes 15 matched with the pipes 2 5 are opened on the support frame 7. And the length of the cross block 14 is greater than the width of the sliding hole 15; the setting of the cross block 14 plays a supporting role for the corresponding pipe 2 5, so that the pipe 2 5 receives the limiting and supporting effect provided by the support frame 7, so that the pipe 2 5 can only slide along its length direction relative to the support frame 7. Further, an elastic pad can be arranged on the side of the cross block 14 close to the support frame 7. The elastic pad can be made of rubber material. The elasticity of the elastic pad is used to prevent the cross block 14 from directly contacting the support frame 7.

[0022] A power assembly matched with the two reciprocating screw assemblies 8 is installed on the support frame 7; the power assembly includes a servo motor 1 9, a shaft 1 10, a one-way bearing 1 11, and a helical gear 12. A servo motor 1 9 is fixedly installed on the support frame 7. The driving end of the servo motor 1 9 is fixedly installed with a shaft 1 10. A helical gear 12 is installed on the shaft 1 10 through the one-way bearing 1 11. A helical gear 12 is also fixedly installed at one end of the two reciprocating screw assemblies 8 close to each other. And the helical gear 12 above is meshed with the two helical gears 12 below. From the description attached Figure 5 And attached Figure 6In all of them, the helical gear 12 installed on the reciprocating screw assembly 8 can be seen, but the diameter of this helical gear 12 is smaller than that of the helical gear 12 installed on the one-way bearing 11; at the end where the two reciprocating screw assemblies 8 are close to each other, there is no support shown in the figure. The two can be connected in a rotatable installation manner to support each other, or a support block can be fixedly installed at the middle position of the support frame 7, and then the ends where the two reciprocating screw assemblies 8 are close to each other can be rotatably arranged on this support block.

[0023] Refer to Figures 1 - 15 As shown in the figure, a blanking component is installed between the first pipe 4, the second pipe 5 and the seed box 3. The blanking component includes a first blanking pipe 6, a blanking box 16 and a shielding component. The blanking box 16 is fixedly installed on the placement table 2, and a seeding pipe is fixedly connected between the blanking box 16 and the seed box 3. A first blanking pipe 6 is fixedly connected between the first pipe 4, the second pipe 5 and the blanking box 16. The two ends of the first blanking pipe 6 connected to the second pipe 5 are hard pipes, and the middle position is a telescopic elastic hose, so as to meet the movement requirements of the second pipe 5. At the same time, a shielding component cooperating with a plurality of first blanking pipes 6 is installed between the first shaft 10 and the blanking box 16. The shielding component includes a second one-way bearing 17, a first magnetic block 18, a shielding block 19, a moving frame 20 and a second magnetic block 21. Two first magnetic blocks 18 are installed at the upper end of the first shaft 10 through the second one-way bearing 17. The self-locking direction of the second one-way bearing 17 is opposite to that of the first one-way bearing 11. The magnetic properties on the sides where the two first magnetic blocks 18 are away from each other are opposite. A shielding member is installed on the blanking box 16, and a second magnetic block 21 is fixedly installed on the part of the shielding member outside the blanking box 16. The shielding member includes a shielding block 19, a round rod and a moving frame 20. A plurality of shielding blocks 19 cooperating with the upper ports of the first blanking pipes 6 are slidably installed in the blanking box 16. A round rod is fixedly installed on one side of each shielding block 19. A plurality of round rods all hermetically slide through the blanking box 16 and are fixedly installed with a moving frame 20 together. The second magnetic block 21 is fixedly arranged through a rod frame and the second magnetic block 21. The setting of the rod frame enables the second magnetic block 21 to meet the movement requirements of the shielding block 19 when reciprocating under the action of the first magnetic block 18, and will not be in direct contact with the first magnetic block 18, meeting the operation requirements of this part as a whole.

[0024] Refer to Figures 1 - 15, a seed dropping sensor 22 is fixedly installed at the lower end of each of the first pipe 4 and the second pipe 5 on the support frame 7 and is used in cooperation with the above-mentioned control system and intelligent decision-making module; the seed dropping sensor 22 is a sensor used in the agricultural field and is mainly used to monitor and detect whether seeds successfully fall into the soil during sowing. Its working principle is usually based on physical, optical, acoustic or electrical detection methods; for example, an optical sensor is based on the principle of light reflection or occlusion. The optical sensor emits a light beam of a certain frequency (such as infrared light, laser beam, etc.). When the seeds fall from the seeder, it will affect the propagation of the light beam. When the sensor detects the change in light, it can determine whether the seeds have successfully fallen. Another example is that a photoelectric sensor detects the presence of an object by emitting and receiving light. Common ones include reflective photoelectric sensors and transmissive photoelectric sensors. The reflective photoelectric sensor determines whether an object has passed by detecting the reflected light, while the transmissive photoelectric sensor determines whether there is an object blocking the light.

[0025] Refer to Figures 1 - 15 , an installation frame 23 is fixedly installed at both ends of the support frame 7. A second moving seat 34 is installed on the installation frame 23 through a reseeding driving member. The reseeding driving member is used to horizontally move and adjust the reseeding seeds when the seed dropping sensor 22 detects missed sowing. The reseeding driving member includes a second servo motor 24, a one-way bearing three, a first reciprocating screw 26, a second ball nut, a second moving seat 34, and a second material discharging pipe 41. A second servo motor 24 is fixedly installed on one of the installation frames 23. A one-way bearing three and a one-way bearing four are installed on the driving end of the second servo motor 24, and the one-way bearing four is located between the second servo motor 24 and the one-way bearing three. The self-locking directions of the one-way bearing three and the one-way bearing four are opposite. A first reciprocating screw 26 is fixedly installed on the one-way bearing three. A second moving seat 34 is installed on the first reciprocating screw 26 through a second ball nut. A rotating rod 42 is rotatably installed on the second moving seat 34. A reseeding hole 35 is formed on the rotating rod 42. A second material discharging pipe 41 that cooperates with the rotating rod 42 is fixedly connected to the seed box 3. When the rotating rod 42 is located below the second material discharging pipe 41, the second material discharging pipe 41 corresponds to the reseeding hole 35. The second material discharging pipe 41 is provided with an electric valve. When the rotating rod 42 is in Figure 1 the position shown in, the electric valve opens and closes once, and the seeds to be reseeded are filled through the second material discharging pipe 41 onto the reseeding hole 35.

[0026] A baffle plate 36 is slidably mounted on the rotating rod 42. For example, a strip-shaped stepped sliding groove is formed on the lower surface of the rotating rod 42, and a stepped block 43 is fixedly mounted on the baffle plate 36 and is matched with the strip-shaped stepped sliding groove. The stepped block 43 can slide in the strip-shaped stepped sliding groove, so that the baffle plate 36 can slide relative to the rotating rod 42 as required, but there is no relative movement in the vertical direction between the two; an opening and closing assembly is installed between the baffle plate 36 and the second moving seat 34; the opening and closing assembly includes a connecting rod 37, a first magnetic block 38, a second magnetic block 39, and a third magnetic block. A connecting rod 37 is fixedly mounted on one side of the baffle plate 36, and a first magnetic block 38 is fixedly mounted at one end of the connecting rod 37. A second magnetic block 39 and a third magnetic block (not shown in the figure) are fixedly mounted on the second moving seat 34, and the second magnetic block 39 and the third magnetic block are respectively located on two adjacent side surfaces of the second moving seat 34, and the magnetic sides of the second magnetic block 39 and the third magnetic block away from the second moving seat 34 are opposite, and the magnetic of the third magnetic block is the same as that of the first magnetic block 38 away from one end of the connecting rod 37. When the first magnetic block 38 corresponds to the third magnetic block, it is repelled and thus in the farthest position. At this time, the baffle plate 36 blocks the reseeding hole 35. When the first magnetic block 38 corresponds to the second magnetic block 39, the first magnetic block 38 is attracted and thus in the nearest position, so that the baffle plate 36 moves away from the reseeding hole 35 for the required reseeding and feeding.

[0027] Referring to Figures 1 - 15 , a control and direction-changing member (one set of reseeding driving member and one set of control and direction-changing member are provided in the figure. Specifically, multiple sets can be provided as required) that cooperates with the reseeding driving member is installed between the two mounting frames 23.

A rod body 25 is rotatably mounted between the two mounting frames 23, and a transmission gear 27 is fixedly mounted on both the rod body 25 and the one-way bearing four. The two transmission gears 27 are meshed with each other. A housing 40 is fixedly mounted on the mounting frame 23 where the second servo motor 24 is installed, and the two transmission gears 27 are both located inside the housing 40. The rod body 25, the first reciprocating screw 26, and the driving end all rotatably penetrate through the housing 40. The housing 40 plays a role in shielding and protecting the two transmission gears 27; a rack 28 is installed on the rod body 25 through the control structure, and a synchronous movement structure is installed between the rack 28 and the second moving seat 34. A gear 31 is coaxially and fixedly mounted on the rotating rod 42, and the gear 31 is meshed with the rack 28.

[0028] The control structure includes a reciprocating screw two 29, a strip-shaped rod 30, a gear 31, and a ball nut three. A plurality of strip-shaped rods 30 are fixedly installed on the rod body 25. A ball nut three is installed inside the rack 28. The reciprocating screw two 29 is installed on the ball nut three. The reciprocating screw two 29 is hollow, and strip-shaped sliding grooves matching the strip-shaped rods 30 are formed on the inner wall of the reciprocating screw two 29. The synchronous movement structure includes a fixed rod 32, a stepped plate 33, and a moving seat two 34. The rack 28 is fixedly installed with a stepped plate 33 through a plurality of fixed rods 32.

[0029] Further explanation, the above fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0030] In the present invention, for the convenience of understanding, the positions shown in the specification drawings are set as the initial state. The servo motor one 9, the servo motor two 24, and the seed dropping sensor 22 are all controlled by the satellite radar ground wheel speed measuring component, which is convenient for sowing regulation according to the specific sowing area and the traveling speed of the machine body 1. Adjust the distance of the pipe two 5 according to the specific sowing situation; turn on the servo motor one 9, and the servo motor one 9 drives the shaft body one 10 to rotate. The rotation of the shaft body one 10 drives the helical gear 12 to rotate through the one-way bearing one 11. The rotation of the upper helical gear 12 drives the two helical gears 12 installed on the reciprocating screw assembly 8 to rotate together, and then drives the two reciprocating screw assemblies 8 to rotate. The rotation of the reciprocating screw assembly 8 drives the moving seat one 13 thereon to move, and then drives the pipe two 5 to move.
