Description

Technical Field

[0001] The invention relates to a crop combined seeder applying Beidou positioning and a work flow. 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 open 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 cover.

[0003] For example, CN105993250A is a multifunctional agricultural soil loosening, fertilizing and seeding machine. Although it discloses a technical solution, in practice, due to the distance between fertilizer and seeds, a lot of fertilizer is wasted. At the same time, the seeds cannot fully absorb it, resulting in the inability of the roots to take root better and poor resistance to lodging. However, if the fertilizer and seeds are sown at the same time, the fertilizer will cause the seeds to burn. How to avoid burning the seeds and at the same time, fully utilize the fertilizer and achieve better rooting has become a technical problem that needs to be solved urgently.

[0004] As the "Optimization of Wheat Seeder Control System Based on Beidou Positioning" in "Agricultural Mechanization Research", the wheat plot seeder is mainly composed of engine, cab, electronic control operation screen, gearbox transmission device, cone grid seeding device, seeding seat, whole machine frame, seed box bracket, furrow opener device, operation guide frame, front and rear axle steering mechanism, stepper motor, DC motor, electromagnet, electric control box, display screen and Beidou antenna and other main components. The system workflow is as follows: through the Beidou antenna installed on the top of the seeder, the Beidou signal message is received, the controller interprets the message, obtains the real-time coordinates of the seeder, and calculates the distance difference between the two coordinates in real time; according to the ratio, the distance difference is converted into the number of pulses output to the stepper motor, and the stepper motor controls the cone grid seeding device to evenly distribute the seeds. However, it cannot solve the above technical problems.

[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 a working process using Beidou positioning.

[0008] 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] A main wheel set for active forward movement is arranged on the main frame;

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

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

[0013] A front soil-breaking assembly is arranged in front of the plowshare assembly to break the topsoil layer;

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

[0018] In order to provide power to each power component, a main transmission shaft group is set on the main frame, which is used to connect with the towing tractor and serve as the active driving power source; it can be connected to the power box and realize power output through the chain. The chains of each part are not drawn in the figure.

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

[0026] The front earth-breaking assembly comprises an earth-breaking crossbeam arranged on the main frame; and an earth-breaking knife is arranged below the earth-breaking crossbeam.

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

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

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

[0030] The V-shaped harrow plate corresponds to the plowshare head; the plowshare head corresponds to the earth-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, one side of the seed box assembly is also equipped with a water tank and / or a fertilizer tank.

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

[0037] In order to realize the 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 with the rear frame and adjust the height of the soil-breaking knife; then, connect the main frame with the tractor to carry out the sowing operation;

[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 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 rear output shaft of the tractor provides power through the main drive shaft group;

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

[0049] In order to facilitate the later intelligent operation, a joint sowing workflow of crops using Beidou positioning is proposed, and the workflow includes the following steps:

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

[0051] Then, the above planter location is associated 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 achieves positioning through the Beidou positioning module.

[0054] In general, the present invention realizes the precise operation of seeding, fertilizer and soil, avoids the waste of fertilizer and water, makes the seed root system grow better, takes 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 by first breaking the soil to reduce the forward resistance of the plowshare, and then digging furrows again on the ridges, thereby achieving accurate soil covering of the sowing mixture and controlling the amount of soil covering to avoid being too deep or too shallow, thereby effectively maintaining water and fertilizer.
