Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 shows a schematic structural block diagram of a sowing device provided by an embodiment of the present invention, the sowing device includes a controller 210, a speed measuring radar 220, an actuator 230, and a sowing monitor 240, wherein the speed measuring radar 220, the actuator 230, and the sowing monitor 240 are all electrically connected to the controller 210.
Referring to fig. 2 for details, fig. 2 is a sowing method provided by an embodiment of the present invention, and the sowing method is applied to the sowing apparatus shown in fig. 1, and the method includes:
in step S110, the controller 210 receives the driving speed of the seeding vehicle measured by the speed measuring radar 220, and calculates the driving distance of the seeding vehicle in unit time.
The controller 210 may be a Central Processing Unit (CPU), an Electronic Control Unit (ECU), or a combination of a CPU and an ECU. The particular type of controller 210 should not be construed as limiting the invention.
The speed measuring radar 220 can measure the running speed of the seeding vehicle on the ground by transmitting signal waves to the ground and receiving the returned signal waves; the speed measuring radar 220 can also measure the running speed of the seeding vehicle, the speed measuring radar 220 can irradiate the seeding vehicle by transmitting electromagnetic waves and receive the echo of the seeding vehicle, so as to obtain the distance from the seeding vehicle to the electromagnetic wave transmitting point and the distance change rate (i.e. the running speed of the seeding vehicle), and the way of obtaining the running speed of the seeding vehicle by the speed measuring radar 220 should not be construed as limiting the invention. The speed measuring radar 220 transmits the running speed of the seeding vehicle to the controller 210 after obtaining the running speed. The controller 210 calculates a distance traveled by the sowing vehicle per unit time according to the travel speed.
For example, if the travel speed is a meters/second, the controller 210 may obtain that the travel distance of the sowing vehicle per 1 second is a meters.
In step S120, the controller 210 calculates the rotation number of the actuator 230 in the unit time according to the travel distance of the sowing vehicle in the unit time and the planned planting distance of the crops to be sowed.
The planned planting distance of the to-be-sown crops is the distance between two adjacent to-be-sown crops of the multiple to-be-sown crops in the plan, and the executing element 230 is an element driven by the controller 210, and can be a motor or an electric signal variable regulating valve for controlling a hydraulic motor. If the planned planting distance of the crops to be sown is not b meters, the number of the seeds of the crops to be sown in unit time of 1 second is a/b seeds.
Since the actuating element 230 rotates to drive the sowing tray to rotate, a fixed amount of seeds can be uniformly sown by each rotation of the sowing tray. The number of revolutions per unit time that the actuator 230 rotates can thus be calculated from the number of seeds of the crop to be sown that have to be sown per unit time.
Since the embodiment of the invention adjusts the seeding amount in real time according to the running speed of the seeding vehicle, when the running speed of the seeding vehicle is increased, the rotating speed of the actuating element 230 in unit time is increased; when the running speed of the seeding vehicle is reduced, the number of revolutions of the actuating element 230 rotating in unit time is reduced, compared with the existing seeding control depending on land wheel mechanical transmission, the seeding method provided by the embodiment of the invention is more accurate, is not influenced by land wheel transmission errors, abrasion, slippage and the like, is not limited by the running speed of the seeding vehicle, and greatly improves the efficiency of seeding operation. Moreover, when the soil is moist and the straw amount is large, the land wheel transmission control in the prior art is limited by the soil condition and cannot complete the operation.
Alternatively, the sowing operation of the crop to be sown can be completed by the above method, and when the sown crop needs to be fertilized, the operation can still be performed by the above method, and the actuator 230 for controlling the fertilization can be an electric signal variable control valve for controlling a hydraulic motor. The electric signal variable regulating valve can feed the current rotating speed condition of the motor back to the controller 210; and may also receive commands from controller 210 to adjust the amount of oil in and out of the hydraulic motor. When the oil inlet and outlet quantity is increased, the rotating speed of the hydraulic motor is increased; when the oil inlet and outlet amount is reduced, the rotation speed of the hydraulic motor is reduced, so that the rotation speed of the hydraulic motor is controlled. The other end of the hydraulic motor is communicated with the fertilizer discharging stranding cage through a mechanical connecting shaft, and the fertilizer discharging stranding cage is high in rotating speed and large in fertilizer discharging amount; the rotation speed of the stranding cage is slow, and the fertilizer discharge amount is small.
Referring to fig. 3, in an embodiment, before step S120, the method may further include steps S101 to S102 as follows:
in step S101, the controller 210 acquires the number of sowable rows of the sowing vehicle, the sowing row spacing of the sowing vehicle, and the number to be sowed per unit area.
The sowing row number of the sowing vehicle refers to the row number of seeds which can be sown by the sowing vehicle in the running process, and the sowing row spacing of the sowing vehicle is the row spacing of two adjacent sown seeds of the sowing vehicle. The sowing row number of the sowing vehicle and the sowing row spacing of the sowing vehicle can be original attribute parameters of the sowing vehicle. The number to be sown per unit area can be X plants per hectare and can be input by a user through a touch-controllable panel of the sowing apparatus.
In step S102, the controller 210 calculates the planned planting distance of the crop to be sown according to the number of rows of the sowing vehicle, the sowing row spacing of the sowing vehicle, and the number of seeds to be sown per unit area.
The controller 210 can calculate the planned row spacing of the crop to be sown according to the number of the crops to be sown of the single-sided area, and the number of the sowable rows in the attribute parameters of the sowing cart and the sowing row spacing of the sowing cart.
The planned planting distance may be calculated through the above process, and in a specific embodiment, may also be directly input by a user through a touch panel, and the manner of obtaining the planned planting distance should not be construed as a limitation to the embodiments of the present invention.
Referring to fig. 4, in an embodiment, the step S120 specifically includes the following steps S121 to S122:
in step S121, the controller 210 calculates the number of seeds to be sown in the unit time according to the travel distance of the sowing vehicle in the unit time and the planned planting distance of the crops to be sown.
If the running distance of the seeding vehicle in 1 second per unit time is 1 meter and the planned planting distance of the crop to be seeded is 0.1 meter, the number of seeds to be seeded in unit time is 10 (1/0.1).
In step S122, the controller 210 calculates the number of rotations of the actuator 230 in the unit time according to the number of seeds to be sown in the unit time and the fixed number of seeds sown in each rotation of the sowing tray.
The number of revolutions of the actuator 230 per unit of time is a predetermined function of the rotational speed of the sowing disc. The predetermined functional relationship may be such that the number of revolutions of the actuator 230 is the same as the number of revolutions of the sowing disc, i.e. for each revolution of the actuator 230, the sowing disc also rotates one revolution; it is also possible that the disc is rotated in a number of revolutions that is an integer multiple of the number of revolutions of the actuator 230, for example n revolutions of the disc per revolution of the actuator 230.
It is not necessary to set the actuator 230 to rotate one turn to drive the sowing tray to rotate two turns, and the fixed number of seeds that can be sown per turn of the sowing tray is 5 seeds, and then if 10 seeds need to be sown, the sowing tray needs to rotate two turns, that is, the actuator 230 needs to rotate one turn to drive the sowing tray to rotate two turns, so that the number of revolutions of the actuator 230 in unit time is calculated to be one turn.
In a specific implementation manner, the sowing method provided by the embodiment of the present invention may further include the following steps:
the controller 210 receives the actual seeding number per unit time measured by the seeding monitor 240.
The controller 210 calculates the actual planting distance of the crop to be sown according to the actual sowing quantity in the unit time and the running distance of the sowing vehicle in the unit time.
The controller 210 compares the actual planting distance with the planned planting distance, thereby adjusting the number of rotations of the actuator 230 per unit time.
Alternatively, if the actual planting distance is larger than the planned planting distance, which indicates that the number of revolutions of the actuator 230 rotating in the unit time is large, the rotating speed of the actuator 230 is slowed down; if the actual planting distance is smaller than the planned planting distance, which means that the number of revolutions of the actuator 230 rotating in the unit time is small, the rotating speed of the actuator 230 is increased.
In a specific implementation manner, the sowing method provided by the embodiment of the present invention may further include:
and calculating the planned seeding number of the crops to be seeded according to the planned planting distance of the crops to be seeded and the running distance of the seeding vehicle in the unit time.
The controller 210 receives the actual seeding number per unit time measured by the seeding monitor 240.
Then dividing the actual seeding quantity by the planned seeding quantity to obtain the seeding quality accuracy.
If the seeding quality accuracy is lower than a predetermined threshold (e.g., 90%), a seeding error alarm prompt may be output through a display terminal electrically connected to the controller 210 to attract the attention of the user, thereby improving the seeding accuracy.
Referring to fig. 5, fig. 5 is a schematic structural diagram illustrating an embodiment of the sowing plate rotating to drive seeds to move, when the air extractor 120 extracts air, the plurality of air inlets 111 of the negative pressure device 110 generate an air flow to attract seeds to be sown to the gap between the teeth 131 of the sowing plate 130, and the rotating shaft of the actuator rotates to drive the sowing plate 130 to rotate, thereby driving the seeds at the gap between the teeth 131 to move.
The above process realizes that a large number of seeds to be sown are divided into several parts according to a set number, and each of the several parts of seeds is carried by the interval of the gear teeth 131 of the sowing tray 130, and moves along with the rotation of the gear teeth 131 (in fig. 5, the sowing tray 130 can rotate counterclockwise). For example, the interval between every two adjacent teeth 131 of the sowing tray 130 may accommodate one seed, which moves as the gear rotates.
When the gear teeth 131 of the sowing tray 130 rotate to a certain angle, the seeds loaded on the interval of the gear teeth 131 of the angle are separated from the sowing tray 130, thereby realizing the sowing process of the seeds.
When teeth 131 are angled, seeds within the spaces of teeth 131 will fall out of teeth 131 and into rail conduit 170.
The guide rail pipe 170 can adjust the direction of the seeds dropped from the interval of the gear teeth 131, so that the seeds can be dropped more precisely in the trench dug on the ground in advance, and the success rate of the sowing device is improved.
The light source sensor 171 may count the seeds when the seeds pass through, so that the number of actual seeds sowed may be counted, the actual number of seeds sowed may be compared with the number of seeds sowed agreed in advance, and it may be determined whether the sowing is smoothly performed according to a plan.
In particular, there may be instances where adjacent seeds stick. The adhered seeds are sucked to the interval of the teeth 131 of the sowing tray 130 at the same time, and may be simultaneously carried by the interval of the teeth 131, thereby causing a situation that the number of seeds carried by the interval of a certain tooth 131 exceeds a preset number, for example, the number of seeds carried by the interval of a certain tooth 131 is two adhered seeds. Through set up separation blade 160 in the one side of keeping away from negative pressure equipment 110 at seeding dish 130, can be effectual keep off one seed in two seeds of adhesion, it is stable to maintain the quantity that the interval of every teeth of a cogwheel 131 bears the weight of the seed.
In a specific implementation manner, the sowing method provided by the embodiment of the present invention may further include the following steps:
the controller 210 determines whether the electric signal of the actuator 230 operates within a preset range; if not, the controller 210 sends an alarm signal.
The controller 210 can also monitor electrical signals (such as current, voltage, number of revolutions of rotation in unit time, rotating speed and the like) of the actuating element 230 (such as an electrical signal variable regulating valve, a motor and the like), judge whether the electrical signals operate in a preset normal working range, if not, the controller 210 can also control a display terminal electrically connected with the controller 210 to output an abnormal alarm prompt, so that a user can find out in time to check the seeding quality, the aim of monitoring the seeding quality in real time is fulfilled, and the problems that the seeding quality cannot be monitored in time and seeding errors cannot be found in time in the traditional ground wheel type transmission seeding method are solved. For example, when the rotating speed of the stepping motor is excessively high due to abnormality or the seeding rate monitor displays that the seed leakage phenomenon occurs, the phenomenon can be found at the first time and fed back to the display to inform the driver. And traditional ground wheel formula transmission seeding control principle then can't realize the timeliness of seeding quality control, can't discover in time that the seeding is wrong.
