Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a sowing system. Background Art

[0002] With the development of science and technology, although machines cannot completely replace farmers' labor, they have greatly reduced the intensity of farmers' labor. Seeders are important tools for agricultural production and can greatly reduce farmers' labor intensity.

[0003] The prior art with patent number 202120573628.6 discloses a peanut planter, which moves the wedge block while the second connecting rod moves, and the wedge block squeezes the third connecting rod while moving, and the third connecting rod drives the baffle away from the channel, so that the channel is in an open state, at which time the peanut seeds can slide from the inside of the channel. When the wedge block no longer squeezes the third connecting rod, the third connecting rod automatically resets under the action of the spring, that is, the automatic closure of the channel is realized, thereby realizing the function of intermittent sowing;

[0004] The above-mentioned prior art can realize the intermittent sowing function of peanuts by controlling the opening and closing of the channel. However, it cannot control the number of peanuts falling each time the channel is opened, so that the number of seeds in each nest is different, affecting the density of peanut planting. Utility Model Content

[0005] In view of this, the utility model provides a sowing system to solve the problem in the prior art that the number of peanuts sown each time cannot be controlled, resulting in different numbers of seeds in each nest, which affects the density of peanut planting.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A sowing system comprises a main frame, wherein a silo is provided on the main frame, wherein the silo has a discharge port, and above the discharge port is provided:

[0008] A coarse sowing structure for delivering the seeds in the silo to a discharge port;

[0009] A fine sowing structure for delivering the seeds in the silo to the discharging port to supplement the seeds that are insufficiently discharged by the coarse sowing structure;

[0010] The main frame is also provided with a lifting device and a duckbill. The duckbill is located below the discharge port. The duckbill is driven by a driving device to open or close. The lifting device can drive the duckbill to rise or fall.

[0011] In this technical scheme, it should be noted that, in this scheme, the coarse sowing structure can be an intermittent discharging structure with channel opening and closing disclosed in Patent No. 202120573628.6, or a combination structure of a rotating disk and a quantitative groove disclosed in Patent No. 201820274180.6; because the particle size of the seeds is screened before sowing, generally smaller seeds are eliminated, therefore, when sowing with the above two structures, the number of seeds sown may be less than the preset number. Based on this, a fine sowing structure is added in this scheme, and the fine sowing structure can be a single seed discharging structure in the prior art, that is, each When the one-time precision sowing structure is used, a seed will fall from the discharge port. When the present solution uses the present sowing structure, the mobile frame drives the silo to move. When the sowing position is reached, the seeds in the silo are sent to the discharge port through the coarse discharge port for sowing. When the number of seeds is less than the preset value, for example, the number of seeds is less than 2, the two seeds in the silo are discharged by using the two-time precision sowing structure to supplement the number. In summary, the present invention uses the coarse sowing structure for preliminary sowing. When the number of discharged seeds is less than the preset value, the fine sowing structure is used to supplement the number, thereby achieving accurate sowing of seeds.

[0012] Secondly, in this scheme, a duckbill, a driving device and a lifting device are provided. During sowing, after the seeds fall into the duckbill through the discharge port, the lifting device drives the duckbill to move downward, so that the duckbill with the seeds is inserted into the soil, and then the driving device drives the bottom of the duckbill to open, and the seeds fall into the soil by gravity, thereby completing the sowing work.

[0013] Preferably, the lifting device includes a frame and a screw, the frame is fixed on the main frame, the screw is vertically arranged and rotatably connected to the frame, the screw is driven by an electric motor, a movable seat is screwed on the screw, and the movable seat is connected to the duckbill through a mounting plate.

[0014] In this technical solution, it should be noted that the lead screw is rotatably connected to the frame through a bearing, the movable seat is in contact with the frame, and the frame can limit the rotation of the movable seat. When it is necessary to drive the duckbill to rise or fall, the motor is started, and the motor drives the lead screw to rotate, so that the movable seat threadedly connected to the lead screw rises or falls, and the rise or fall of the movable seat drives the duckbill to rise or fall.

[0015] Preferably, the duckbill includes a fixed shell and a rotating shell, the fixed shell and the rotating shell are interlocked, the fixed shell is fixed on a mounting plate, and the rotating shell is hinged to the fixed shell; the driving device includes a driving motor, the driving motor is fixed on the mounting plate, a first transmission rod is fixedly connected to the main shaft of the driving motor, a second transmission rod is hinged on the end of the first transmission rod, and the bottom of the second transmission rod is hinged to the rotating shell.

[0016] In this technical solution, it should be noted that when the duckbill needs to be driven open, the driving motor drives the first rotating rod to rotate a certain angle, and the first transmission rod drives the second rotating rod to rotate a certain angle, so that the rotating shell rotates away from the fixed shell, thereby opening the bottom of the duckbill and the seeds fall from the bottom of the duckbill due to gravity.

[0017] Preferably, a hopper is also fixed on the mounting plate, with the top of the hopper facing the discharge port and the bottom of the hopper facing the duckbill.

[0018] In this technical solution, it should be noted that the top opening of the hopper is larger and the bottom opening is smaller, which is used to catch the seeds falling from the discharge port.

[0019] Preferably, the coarse sowing structure includes a first rotating member rotatably connected to the silo, the first rotating member is provided with a first containing structure for containing seeds, and the first rotating member rotates the first containing structure to the discharge port by rotating; the fine sowing structure includes a second rotating member rotatably connected to the silo, the second rotating member is provided with a second containing structure for containing seeds.

[0020] In this technical scheme, it should be noted that, in this scheme, the coarse sowing structure and the fine sowing structure can adopt the rotating disk rotating discharging structure disclosed in Patent No. 201820274180.6, and the first containing structure and the second containing structure can be the quantitative slot structure disclosed in Patent No. 201820274180.6, wherein, since the seeds are screened for their particle size before sowing, generally speaking, the seed capacity of the first containing structure will only be less than or equal to the preset number. In this scheme, the seed capacity of the first containing structure is preferably 3 seeds, and the capacity is based on seeds of standard particle size; in addition, the capacity of the second containing structure is preferably 1 seed.

[0021] Preferably, the first rotating member includes a first rotating disk rotatably connected to the silo, and the first containing structure includes a containing slot assembly provided on the side wall of the first rotating disk; the second rotating member includes a second rotating disk rotatably connected to the silo and located on one side of the first rotating disk, and the second containing structure includes a second containing slot provided on the second rotating disk, and the volume of the second containing slot is smaller than the volume of the containing slot assembly. The containing slot assembly includes a plurality of first containing slots spaced apart along the axial direction of the first rotating disk, and the containing slot assemblies are multiple, and the plurality of containing slot assemblies are spaced apart equidistantly along the circumference of the first rotating disk. The plurality of second containing slots are multiple, and the plurality of second containing slots are spaced apart equidistantly along the circumference of the second rotating disk.

[0022] In this technical solution, it should be noted that the number of first receiving slots in each group of receiving slot assemblies is 3; the seed holding capacity of the first receiving slot and the second receiving slot is 1 seed, and the holding capacity is based on seeds of standard particle size. Because seeds smaller than the standard particle size will be screened out before sowing, in this solution, each first receiving slot can hold at most one seed or cannot hold seeds with too large a particle size, that is, one receiving slot assembly can hold at most 3 seeds and at least 0 seeds, while the second receiving slot can hold at most one seed and at least 0 seeds; when using the seeder in this solution, first add a number of screened seeds into the silo, and then add some of the seeds that have been screened into the silo. The seeds fall into the corresponding first and second receiving grooves. When sowing is required, the first turntable is rotated by a certain angle so that the receiving groove assembly with the seeds rotates from the inside of the silo to a position opposite to the discharge port. At this time, due to the action of gravity, the seeds fall from the first receiving groove into the soil. If the number of seeds is less than the preset amount, for example, 3 seeds should be sown, but there are actually only two seeds, the second turntable is rotated by a certain angle so that the first receiving groove containing a single seed rotates to the discharge port to supplement the missing seeds. It should be noted that if there is no seed in the first receiving groove, the first turntable can be rotated multiple times until a single seed falls from the discharge port.

[0023] Preferably, the first rotating member is driven by a first motor, and the second rotating member is driven by a second motor.

[0024] In this technical solution, it should be noted that in this technical solution, the two turntables are driven by motors to reduce the work intensity of the staff. In addition, a control button for controlling the opening and closing of the two motors can be set on the frame used to support the silo. Secondly, in this solution, since both motors are stepper motors, the stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction; that is, in this solution, starting the stepper motor once is to achieve a sowing operation.

[0025] Preferably, an observation window is provided on the side wall of the silo, a camera is provided on one side of the observation window, the camera faces the first rotating member and the second moving member, the camera, the first motor and the second motor are electrically connected to an external control system respectively. The first motor and the second motor are both stepping motors.

[0026] In this technical solution, it should be noted that in this solution, the number of seeds in the receiving tank assembly and the second receiving tank is observed by a camera. If the number of seeds in the receiving tank assembly is too small, the first motor is controlled to start to drive the first turntable to rotate a fixed angle so that the seeds in the receiving tank fall down. At the same time, the second motor is controlled to drive the second turntable to rotate to supplement the missing number of seeds with the seeds in the second receiving tank. The specific method is as follows:

[0027] Step S1: The image of the receiving slot assembly on the opposite side of the observation window is obtained by a camera, and the control system obtains the number of seeds in the receiving slot based on the image, and annotates the image based on the number of seeds, and divides the image into four types of marks: the receiving slot assembly has no seeds, 1 seed, 2 seeds, and 3 seeds, and sets the target frame labels as S0, S1, S2, and S3 respectively;

[0028] Step S2: The labeled images are made into a data set, and the data set is trained based on the YOLOv8 algorithm to obtain a recognition model;

[0029] Step S3: During sowing, the camera obtains an image of the receiving slot assembly on the opposite side of the observation window, and inputs the image into a recognition model, wherein the recognition model obtains the number of seeds in the receiving slot assembly based on the image;

[0030] Step S4: The control system controls the first motor to start, and the first motor drives the first turntable to rotate the receiving slot assembly to the discharge port for rough sowing. At the same time, the control system determines the missing amount of seeds according to the number of seeds in the receiving slot assembly. When the system detects that seeds are missing, that is, the number of seeds is S0, S1, S2, or S3, the control system controls the second motor to drive the second turntable to rotate to a set angle based on the missing amount, so as to rotate the second receiving slot to the discharge port to supplement the missing amount of seeds.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0032] 1. The utility model uses a coarse sowing structure for preliminary sowing. When the number of seeds discharged is less than the preset value, the fine sowing structure is used to supplement the seeds, thereby achieving accurate sowing of seeds;

[0033] 2. In the utility model, a duckbill, a driving device and a lifting device are provided. When sowing, after the seeds fall into the duckbill through the discharge port, the lifting device drives the duckbill to move downward, so that the duckbill with the seeds is inserted into the soil, and then the driving device drives the bottom of the duckbill to open, and the seeds fall into the soil by gravity, thereby completing the sowing work.

[0049] Example 1

[0050] like Figure 1-Figure 7 As shown, the utility model discloses a sowing system in an embodiment, including a main frame 10, on which a silo 20 is provided, and the silo 20 has a discharge port 21, and above the discharge port 21 there are:

[0051] A coarse sowing structure for delivering the seeds in the silo 20 to the discharge port 21;

[0052] A fine sowing structure for delivering the seeds in the silo 20 to the discharge port 21 to supplement the seeds that are insufficiently discharged by the coarse sowing structure;

[0053] The main frame 10 is also provided with a lifting device and a duckbill 85. The duckbill 85 is located below the discharge port 21. The duckbill 85 is driven to open or close by a driving device, and the lifting device can drive the duckbill 85 to rise or fall. It should be noted that in the present scheme, the coarse sowing structure can be an intermittent discharging structure for opening and closing a channel disclosed in Patent No. 202120573628.6, or it can be a combination structure of a rotating disk and a quantitative groove disclosed in Patent No. 201820274180.6; because the particle size of the seeds is screened before sowing, generally smaller seeds are eliminated. Therefore, when sowing with the above two structures, the number of seeds sown may be less than the preset number. Based on this, a precision sowing structure is added in the present scheme. The precision sowing structure can be a single seed discharging structure in the prior art, that is, each time the precision sowing structure is used, When the seeding structure is used, the silo 20 is moved by the mobile frame. When the seeding position is reached, the seeds in the silo 20 are sent to the discharge port 21 for sowing through the rough discharge port 21. When the number of seeds is less than the preset value, for example, the number of seeds is less than 2, the two seeds in the silo are discharged by using the two-time precision sowing structure to supplement the number. In summary, the coarse sowing structure is set for preliminary sowing in the utility model. When the number of discharged seeds is less than the preset value, the fine sowing structure is used to supplement the number, so as to achieve accurate sowing of seeds.

[0054] Secondly, in this scheme, a duckbill 85, a driving device and a lifting device are provided. During sowing, after the seeds fall into the duckbill 85 through the discharge port 21, the lifting device drives the duckbill 85 to move downward, so that the duckbill 85 is inserted into the soil with the seeds, and then the driving device drives the bottom of the duckbill 85 to open, and the seeds fall into the soil by gravity, thereby completing the sowing work.

[0055] Example 2

[0056] like Figure 6 and Figure 7 As shown, this embodiment is substantially the same as the above embodiment, except that the lifting device includes a frame 80 and a lead screw 83, the frame 80 is fixed on the main frame 10, the lead screw 83 is vertically arranged and rotatably connected with the frame 80, the lead screw 83 is driven by a motor 81, a movable seat 82 is screwed on the lead screw 83, and the movable seat 82 is connected with the duckbill 85 through a mounting plate 84. It should be noted that the lead screw 83 is rotatably connected with the frame 80 through a bearing, the movable seat 82 is in contact with the frame 80, and the frame 80 can limit the rotation of the movable seat 82. When it is necessary to drive the duckbill 85 to rise or fall, the motor 81 is started, and the motor 81 drives the lead screw 83 to rotate, so that the movable seat 82 threadedly connected with the lead screw 83 rises or falls, and the rise or fall of the movable seat 82 drives the duckbill 85 to rise or fall.

[0057] like Figure 6 and Figure 7 As shown, in this embodiment, the duckbill 85 includes a fixed shell 851 and a rotating shell 852, the fixed shell 851 and the rotating shell 852 are interlocked, the fixed shell 851 is fixed on the mounting plate 84, and the rotating shell 852 is hinged to the fixed shell 851; the driving device includes a driving machine 87, the driving machine 87 is fixed on the mounting plate 84, and a first transmission rod 872 is fixedly connected to the main shaft 871 of the driving machine 87, the end of the first transmission rod 872 is hinged to the second transmission rod 873, and the bottom of the second transmission rod 873 is hinged to the rotating shell 852. It should be noted that when it is necessary to drive the duckbill 85 to open, the driving machine 87 drives the first rotating rod to rotate a certain angle, and the first transmission rod 872 drives the second rotating rod to rotate a certain angle, so that the rotating shell 852 rotates in a direction away from the fixed shell 851, thereby opening the bottom of the duckbill 85, and the seeds fall from the bottom of the duckbill 85 by gravity.

[0058] like Figure 6 and Figure 7 As shown, in this embodiment, a hopper 86 is also fixed on the mounting plate 84, the top of the hopper 86 faces the discharge port 21, and the bottom of the hopper 86 faces the duckbill 85. It should be noted that the top opening of the hopper 86 is larger and the bottom opening is smaller, which is used to catch the seeds falling from the discharge port 21.

[0059] Example 3

[0060] like Figure 1-Figure 5 As shown, this embodiment is substantially the same as the above embodiment, except that the coarse seeding structure includes a first rotating member rotatably connected to the silo 20, the first rotating member is provided with a first containing structure for containing seeds, and the first rotating member rotates the first containing structure to the discharge port 21 by rotation; the fine seeding structure includes a second rotating member rotatably connected to the silo 20, and the second rotating member is provided with a second containing structure for containing seeds. It should be noted that in this solution, the coarse seeding structure and the fine seeding structure can adopt the rotating disk rotating discharge structure disclosed in patent number 201820274180.6, and the first containing structure and the second containing structure can be the quantitative slot structure disclosed in patent number 201820274180.6, wherein, since the particle size of the seeds is screened before sowing, generally speaking, the seed containing quantity of the first containing structure will only be less than or equal to the preset quantity. In this solution, the seed containing capacity of the first containing structure is preferably 3 seeds, and the containing capacity is based on the seeds of standard particle size; in addition, the containing capacity of the second containing structure is preferably 1 seed.

[0061] like Figure 2-Figure 5As shown, in this embodiment, the first rotating member includes a first rotating disk 30 rotatably connected to the silo 20, and the first containing structure includes a containing tank assembly 32 provided on the side wall of the first rotating disk 30; the second rotating member includes a second rotating disk 40 rotatably connected to the silo 20 and located on one side of the first rotating disk 30, and the second containing structure includes a second containing tank 41 provided on the second rotating disk 40, and the volume of the second containing tank 41 is smaller than the volume of the containing tank assembly 32. The containing tank assembly 32 includes a plurality of first containing tanks 31 spaced apart along the axial direction of the first rotating disk 30, and the containing tank assembly 32 is a plurality of, and the plurality of containing tank assemblies 32 are spaced apart equidistantly along the circumference of the first rotating disk 30. The plurality of second containing tanks 41 are a plurality of, and the plurality of second containing tanks 41 are spaced apart equidistantly along the circumference of the second rotating disk 40. It should be noted that the number of first receiving slots 31 in each group of receiving slot assemblies 32 is 3; the seed holding capacity of the first receiving slot 31 and the second receiving slot 41 is 1 seed, and the holding capacity is based on seeds of standard particle size. Because seeds smaller than the standard particle size will be screened out before sowing, in this solution, each first receiving slot 31 can hold at most one seed or cannot hold seeds with too large a particle size, that is, one receiving slot assembly 32 can hold at most 3 seeds and at least 0 seeds, while the second receiving slot 41 can hold at most one seed and at least 0 seeds; when using the seeder in this solution, first add a number of screened seeds to the silo 20, and some seeds fall into In the corresponding first receiving groove and second receiving groove, when sowing is required, the first turntable 30 is rotated by a certain angle so that the receiving groove assembly 32 with seeds is rotated from the inside of the silo 20 to a position opposite to the discharge port 21. At this time, due to the action of gravity, the seeds fall from the first receiving groove 31 into the soil. If the number of seeds is less than the preset amount, for example, 3 seeds should be sown, but there are actually only two seeds, the second turntable 40 is rotated by a certain angle at this time so that the second receiving groove containing a single seed is rotated to the discharge port 21 to make up for the missing seeds. It should be noted that if there is no seed in the second receiving groove, the second turntable 30 can be rotated multiple times until a single seed falls from the discharge port 21.

[0062] like Figure 2As shown, in this embodiment, the first rotating member is driven by the first motor 23, and the second rotating member is driven by the second motor 24. It should be noted that in this technical solution, the two turntables are driven by motors to reduce the work intensity of the staff. In addition, a control button for controlling the opening and closing of the two motors can be set on the frame used to support the silo 20. Secondly, in this solution, since both motors are stepper motors, the stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction; that is, in this solution, starting the stepper motor once is to achieve a sowing operation.

[0063] like Figure 2 As shown, in this embodiment, an observation window 70 is provided on the side wall of the silo 20, and a camera 22 is provided on one side of the observation window 70, and the camera 22 faces the first rotating member and the second moving member, and the camera 22, the first motor 23 and the second motor 24 are electrically connected to the external control system respectively. The first motor 23 and the second motor 24 are both stepper motors. It should be noted that in this scheme, the number of seeds in the receiving tank assembly 32 and the second receiving tank 41 is observed by the camera 22. If the number of seeds in the receiving tank assembly 32 is too small, the first motor 23 is first controlled to start to drive the first turntable 30 to rotate a fixed angle so that the seeds in the receiving tank fall down, and synchronously, the second motor 24 is controlled to drive the second turntable 40 to rotate to replenish the missing number of seeds in the second receiving tank 41. The specific method is as follows:

[0064] Step S1: The camera 22 obtains an image of the receiving slot assembly 32 on the opposite side of the observation window 70, and the control system obtains the number of seeds in the receiving slot based on the image, and annotates the image based on the number of seeds, and divides the image into four types of marks: no seeds, 1 seed, 2 seeds, and 3 seeds in the receiving slot assembly, and sets the target frame labels to S0, S1, S2, and S3 respectively;

[0065] Step S2: The labeled images are made into a data set, and the data set is trained based on the YOLOv8 algorithm to obtain a recognition model;

[0066] Step S3: During sowing, the camera 22 obtains an image of the receiving tank assembly 32 on the opposite side of the observation window 70 and inputs the image into a recognition model, wherein the recognition model obtains the number of seeds in the receiving tank assembly 32 based on the image;

[0067] Step S4: The control system controls the first motor 23 to start, and the first motor 23 drives the first turntable 30 to rotate the receiving slot assembly 32 to the discharge port 21 for rough sowing. At the same time, the control system determines the missing amount of seeds according to the number of seeds in the receiving slot assembly 32. When the system detects that seeds are missing, that is, the number of seeds is S0, S1, S2, or S3, the system controls the second motor 24 to drive the second turntable 40 to rotate a set angle based on the missing amount, so as to rotate the second receiving slot to the discharge port 21 to supplement the missing amount of seeds.
