Description

Technical Field

[0001] The present invention relates to a crop combined seeder applying Beidou positioning and a working process. Background Art

[0002] With large-scale operations, a large number of combined seeders are widely used. The general operation plan is to first use a plowshare to dig furrows and turn the soil, then sow the seeds through a seeder, and simultaneously apply fertilizer on one side of the seeds, and finally cover the seeds and fertilizers through a coverer.

[0003] For example, CN105993250A is a multifunctional agricultural soil loosening and fertilizing seeder. Although it discloses a technical solution, in practice, due to the distance between fertilizer and seeds, a large amount of fertilizer is wasted. At the same time, the seeds cannot fully absorb it, resulting in the root system being unable to take root well and poor resistance to lodging. However, if fertilizer and seeds are sown at the same time, the fertilizer will cause the seeds to burn. How to avoid burning the seeds while fully utilizing the fertilizer and achieving better rooting has become a technical problem that urgently needs to be solved.

[0004] As part of the "Optimization of Wheat Seeder Control System Based on Beidou Positioning" study in the journal "Agricultural Mechanization Research," the wheat plot seeder consists primarily of an engine, cab, electronic control panel, gearbox transmission, cone-shaped grid seeding mechanism, seeding seat, complete machine frame, seed box bracket, furrow opener, operation guide frame, front and rear axle steering mechanisms, stepper motor, DC motor, electromagnet, electronic control box, display screen, and Beidou antenna. The system operates as follows: A Beidou antenna mounted on top of the seeder receives Beidou signal messages, which the controller interprets to obtain the real-time coordinates of the seeder and calculates the distance difference between the two coordinates in real time. This distance difference is then converted into a proportional number of pulses output to the stepper motor, which controls the cone-shaped grid seeding mechanism to evenly distribute the seeds. However, the system fails to address the aforementioned technical issues.

[0005] Traditional seeders are in direct contact with the soil. Since the soil has a certain humidity, the seeder will stick, resulting in the inability to sow seeds continuously.

[0006] Although the existing technology can realize the positioning of the seed drill, it is unable to reasonably position the seeds and realize the precise field operation in the later stage, and is not suitable for the refined operation in the later stage. Summary of the Invention

[0007] The technical problem to be solved by the present invention is generally to provide a crop combined seeder and work flow using Beidou positioning.

[0008] In order to solve the above problems, the technical solution adopted by the present invention is:

[0009] For the existing construction scheme, a crop combined seeder includes a main frame and a rear frame hinged to the main frame;

[0010] The main frame is provided with a main wheel group for active forward movement;

[0011] A ground wheel member that moves forward with the machine is provided on the rear frame;

[0012] A plowshare assembly is provided on the main frame;

[0017] As a further improvement of the above technical solution:

[0018] To power the various power components, a main drive shaft is mounted on the main frame. This shaft is connected to the tractor and serves as the active drive source. It connects to the power box and outputs power via a chain. The chains are not shown in the figure.

[0019] As a specific introduction, a connecting hole portion and a joint are provided on the main frame for connecting to the rear end of the tractor.

[0027] The main frame is hinged to the rear frame via an articulated shaft;

[0028] A transverse adjustment leg is provided below the rear frame, and a ground wheel is provided below the transverse adjustment leg;

[0029] A V-shaped rake plate is connected below the transverse adjustment leg through a vertical leg member;

[0030] The V-shaped harrow plate corresponds to the plowshare head; the plowshare head corresponds to the soil-breaking knife;

[0031] The seed and fertilizer operation component includes a seed box component and a mud fertilizer component arranged on one side of the seed box component;

[0032] As extended protection, for crops that require more water and fertilizer, a water tank and / or fertilizer tank is also provided on one side of the seed box assembly.

[0033] In order to realize unmanned and intelligent operation in the future, a crop combined seeder using Beidou positioning is proposed, based on the above-mentioned crop combined seeder;

[0034] The main frame is equipped with an electric controller and Beidou positioning module;

[0035] Initial coordinates of crop rows formed by a crop combine planter are set in the field;

[0036] The starting point coordinates and the ending point coordinates of each crop row of the crop combine seeder are recorded relative to the initial coordinates and uploaded to the background server.

[0037] In order to realize combined operation, a crop sowing process is provided, with the aid of the above-mentioned crop combined seeder;

[0038] The workflow of a crop planter, used to plant seeds in a field to form crop rows, performs the following steps;

[0039] First, hinge the main frame to the rear frame and adjust the height of the soil-breaking blade; then, connect the main frame to the tractor for seeding operations;

[0040] When the tractor moves forward,

[0041] First, the soil-breaking knife moves forward to break up the hard soil on the surface of the farmland;

[0042] Then, the plowshares move forward along the opened furrows to turn over the soil and dig furrows;

[0043] Secondly, carry out seed and fertilizer operations;

[0044] Among them, the lower end sheath plowshare head turns the soil or digs furrows on ridges;

[0045] Again, the V-shaped harrow moves forward to cover the furrows where the seeds and the mud-fertilizer mixture are placed.

[0046] As a further improvement of the above technical solution:

[0047] Among them, the tractor's rear output shaft provides power through the main drive shaft group;

[0048] The water tank and / or fertilizer tank are used to supplement watering and / or fertilizing at the trenching location simultaneously.

[0049] In order to facilitate the subsequent intelligent operation, a joint crop sowing workflow using Beidou positioning is proposed. The workflow includes the following steps:

[0050] First, set the geographical coordinates on the farmland;

[0051] Then, associate the above planter location with the geographic coordinates;

[0052] Next, start the seeder to begin the above-mentioned sowing process.

[0053] As a further improvement of the above technical solution, the seeder is positioned through the Beidou positioning module.

[0054] In general, the present invention realizes the precise operation of planting, fertilizing and soiling, avoids the waste of fertilizer and water, makes the seed root system grow better and take root downward, avoids the waste of fertilizer, and at the same time, realizes the improvement of soil, reduces the workload, and avoids the problem of seeder clogging. The vibration amplitude is increased by the clearance match between the vibration and the two T-keys.

[0055] The present invention realizes combined operation, and by breaking the soil first, reducing the forward resistance of the plowshare, and realizing furrowing again on the ridge, the sowing mixture is accurately covered with soil, and the amount of soil covering is controlled to avoid being too deep or too shallow, which can effectively maintain water and fertilizer.

[0085] The seeds dropped quantitatively from the seeder 200 fall through the seed drop opening 212 into the straight groove of the vertically upward central groove 214;

[0086] As the transfer shaft 208 rotates, the central groove 214 drives the seeds to fall to the seed drop opening 212 and then fall out of the transfer box 209 .

[0087] As a preferred improvement, on the return side of the transfer shaft 208, a side opening 240 is provided on the transfer box body 209, a cleaning shaft 206 is provided at the side opening 240, and cleaning brushes 207 are distributed on the cleaning shaft 206;

[0088] The gap between the inner cavity side wall of the transfer cavity 217 and the top of the T-slot 211 is smaller than the outer shape of the seed, and the gap can be filled with rubber or a brush to prevent the seed from being damaged and falling.

[0089] The mixing assembly 202 includes a mixing shell 219; a rotating hollow shaft portion 220 is rotatably arranged in the mixing shell 219; a dividing protrusion 221 is distributed on the side of the rotating hollow shaft portion 220; a lateral channel 222 is passed through the dividing protrusion 221, thereby realizing the discharge of mud fertilizer.

[0091] A mixing drop port 224 is provided below the mixing housing 219. A cutting plate 225 is provided near the upward return side of the mixing drop port 224 to cut off the exposed mud fertilizer and seed mixture and squeeze the remaining mud fertilizer for return.

[0092] In order to achieve better drop of the mixture, the drop assembly 203 includes a drop cone 226 disposed below the mixing drop port 224; a drop channel 227 with an upper end opening is disposed in the drop cone 226;

[0093] An inclined bottom 241 is provided at the lower portion of the falling channel 227 ; a falling opening 229 is provided at the lower outlet of the inclined bottom 241 ; thereby utilizing inertia to enable the mixture to fall into the ditch.

[0098] A mud fertilizer middle through hole 232 is provided at the bottom of the mud fertilizer box 230 and is located below the central optical axis, so that the material can fall.

[0099] The extrusion assembly 205 includes an extrusion box 239; a rotating screw shaft 233 is provided in the extrusion box 239.

[0100] The upper portion of the extrusion box 239 is connected to the mud fertilizer middle through hole 232;

[0101] A guide sleeve 234 is provided on the extrusion box 239.

[0102] The rotating screw shaft 233 passes through the guide sleeve 234;

[0103] A bearing shoulder 242 is provided at the outer end of the rotating spiral shaft 233 and is connected to a bearing bracket;

[0104] A hollow connecting seat 243 is fixedly provided on the side of the extrusion box 239;

[0105] The rotating screw shaft 233 passes through the connecting seat 243; thereby realizing the pushing and output of the mud fertilizer by the auger. Of course, by reverse rotation, the mud fertilizer is mixed with the upper box;

[0106] A mud fertilizer output pipe 235 is connected to the lower end of the connecting seat 243, which is used to connect to the feed rotary joint 223 through a hose;

[0107] An upper buckle cover 236 is provided above the mud fertilizer box 230, and an n-shaped elastic pressure head 237 is provided on the upper buckle cover 236; the pressure head is used to press the mud fertilizer downward for mixing;

[0108] The n-shaped elastic pressure head 237 presses down the mud fertilizer in the mud fertilizer box 230;

[0109] A gearbox assembly 238 is provided on one side of the mud and fertilizer box 230; it can be used to achieve speed regulation, reverse rotation or neutral setting of the seed box and / or the mud and fertilizer box.

[0110] The gearbox assembly 238 is in driving connection with the rotating screw shaft 233 to provide forward and reverse speed change and speed regulation.

[0111] As a working principle, in step A, the seeding device 200 stores seeds to be sown and discharges the seeds downward from the seed drop port 212 in a predetermined amount;

[0112] Step B: In the transfer assembly 201, the quantitative seeds dropped from the seeder 200 are received at the top, and the quantitative seeds are discharged and pressed downward;

[0113] Step C: In the mixing assembly 202, first, the mud fertilizer is continuously fed in. Then, the seeds falling from the transfer assembly 201 are received at the top. Secondly, the seeds are mixed with the mud fertilizer under the pressure of the mud fertilizer during the downward rotation. Finally, the mud fertilizer mixed with seeds is scraped off and falls into the dropping assembly 203.

[0114] Step D: When the seeder moves forward, first, the lower end sheath 228 opens a trench in the field to carry out the construction operation; then, the mud fertilizer mixed with the seeds falls into the trench;

[0115] In step A, step AA is also performed in conjunction with the above, wherein a mixture of soil, fertilizer, and water is pre-prepared in the mud fertilizer assembly 204 and continuously stirred;

[0116] In step C, step CC is also performed in conjunction with the mud fertilizer component 204 sending the mud fertilizer mixture to the extrusion component 205; then, the extrusion component 205 rotates forward to continuously extrude the mud fertilizer into the mixing component 202. When the mud fertilizer is not needed, the extrusion component 205 rotates reversely to continuously stir the mud fertilizer;

[0117] In step B, the transfer shaft 208 rotates, first receiving the falling quantitative seeds from above; then, the seeds fall into the transfer drop port 218 as they rotate in the central groove 214, where they fall. The protrusion of the process T key 215 acts in the straight groove of the central groove 214 through its own gravity and spring force, and the T-shaped guide block 213 shakes up and down in the radial direction of the T-shaped slot 211, so that the seeds fall without sticking.

[0118] When the central groove 214 rotates upward without load, the cleaning brush 207 is driven by the cleaning shaft 206 to clean the central groove 214;

[0119] In step AA, the mud box 230 continuously stirs the mud to prevent it from coagulating and separating. The double screw shaft 231 squeezes and pushes the mud from the mud near the shaft end toward the middle optical axis. During this period, the elastically controlled n-shaped elastic pressure head 237 presses down the mud, so that the mud at the top is continuously stirred and mixed.

[0120] In step C, first, the mud fertilizer enters the inner cavity of the rotating hollow shaft portion 220 through the feed rotary joint 223 and emerges from the graduated lateral channel 222. Then, as the rotating hollow shaft portion 220 rotates, when the lateral channel 222 reaches the upper position, it receives the seeds falling from the transfer drop port 218. Secondly, during the rotation, the seeds and mud fertilizer contact the inner wall of the mixing shell 219 and become immersed in the mud fertilizer and mixed together. Thirdly, when the seeds reach the mixing drop port 224 at the lower position, the gravity of the mud fertilizer and the continuous squeezing force cause the seeds and the mud fertilizer to emerge together. Thereafter, the exposed mud fertilizer contacts the cutting plate 225 and is cut off, and the remaining mud fertilizer is squeezed and the return cycle continues.

[0121] In step CC, first, during the continuous conveying process, the mud fertilizer falls into the extrusion box 239 through the mud fertilizer middle through hole 232. Then, under the action of the rotating screw shaft 233, the mud fertilizer continuously passes through the gap between the rotating screw shaft 233 and the guide sleeve 234, and the inner cavity of the connecting seat 243. It is then output from the mud fertilizer output pipe 235 and delivered to the feed rotary joint 223 through the hose.

[0122] When the supply of slurry fertilizer is not required, the gearbox assembly 238 is shifted so that the rotating screw shaft 233 rotates in the reverse direction;

[0123] In step D, first, then, the cut sludge and seed mixture falls into the falling channel 227 and falls along the inclined bottom 241 into the ditch.

[0124] As a beneficial effect of the present invention, the seeds are dropped by the seeder 200, the seeds are dropped by the transfer component 201, the seeds and mud fertilizer are mixed by the mixing component 202, the dropping component 203 realizes the transfer and dropping of the seeds, the mud fertilizer component 204 realizes the storage, stirring and output of mud fertilizer, the extrusion component 205 realizes the output of mud fertilizer, the cleaning shaft 206 drives the cleaning brush 207 to rotate, which can realize the cleaning of attachments, the transfer shaft body 208 realizes rotation, the transfer box body 209 realizes the dropping of seeds, and the mixture is dropped from the transfer drop port 218 by the dividing protrusion 210, T-slot 211, seed drop port 212, T-guide block 213, center groove 214, process T key 215, vibration spring 216, and transfer inner cavity 217.
