Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture, and in particular relates to a precision seeding structure. 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. Seeder is the main tool for agricultural production.

[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 precise sowing structure to solve the problem that the prior art cannot control the sowing quantity of peanuts each time sowing, 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 precision seeding structure comprises a silo, 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 discharging port;

[0009] The invention is a precision sowing structure for delivering the seeds in the silo to the discharging port and replenishing the missing amount of discharged seeds.

[0010] In this technical solution, it should be noted that the sowing structure can be arranged on a frame, and the sowing structure can be driven to move by the mobile frame; in this solution, the coarse sowing structure can be an intermittent discharging structure with channel opening and closing disclosed in Patent No. 202120573628.6, or a structure combining 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 the situation of quantity, a precision sowing structure is added in this 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, a seed will fall from the discharging port; when using this sowing structure, the scheme drives the silo to move through the mobile frame, and when it reaches the sowing position, the seeds in the silo are sent to the discharging port through the coarse discharging 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 2 seeds in the silo are discharged by using the precision sowing structure twice to supplement the quantity. In summary, the coarse sowing structure set in this utility model is used for preliminary sowing, and when the number of discharged seeds is less than the preset value, it is supplemented by the precision sowing structure to achieve accurate sowing of seeds.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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 receiving groove and the second receiving groove. 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 second receiving groove containing a single seed is rotated to the discharge port to make up for the missing seeds. It should be noted that if the second receiving groove does not contain seeds, the second turntable can be rotated multiple times until a single seed falls from the discharge port.

[0015] Preferably, the first rotating member is driven by a first motor, and the second rotating member is driven by a second motor, and both the first motor and the second motor are stepping motors.

[0016] 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.

[0017] 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 rotating member, and the camera, the first motor and the second motor are electrically connected to an external control system respectively.

[0018] 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 replenish the missing number of seeds in the second receiving tank. The specific method is as follows:

[0019] 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;

[0020] 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;

[0021] 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;

[0022] 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.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0024] 1. In the utility model, the rough sowing structure is provided 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 realizing accurate sowing of seeds;

[0025] 2. In the utility model, the automatic sowing of the rough sowing structure and the fine sowing structure can be realized through the arrangement of the first motor and the second motor of the camera. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figure 1-5 As shown, the embodiment of the utility model discloses a precision seeding structure, including a silo 20, wherein the silo 20 has a discharge port 21, and above the discharge port 21 is provided:

[0041] A coarse sowing structure for delivering the seeds in the silo 20 to the discharge port 21;

[0042] The fine seeding structure is used to deliver the seeds in the silo 20 to the discharge port 21 and replenish the missing amount of discharged seeds.

[0043] It should be noted that the sowing structure can be arranged on the frame 10, and the sowing structure can be driven to move by moving the frame 10; in the present scheme, the coarse sowing structure can be an intermittent discharging structure with channel opening and closing 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 fine sowing structure is added in the present scheme, and the fine sowing structure can be a single seed in the prior art. The discharge structure, that is, each time the precision sowing structure is used, a seed will fall from the discharge port 21; when using the sowing structure, the present solution drives the silo 20 to move by the mobile frame 10, and when it reaches the sowing position, the seeds in the silo 20 are sent to the discharge port 21 through the coarse discharge port 21 for sowing. When the number of seeds is less than the preset value, for example, the number of seeds is less than 2 grains, the 2 seeds in the silo are discharged by using the precision sowing structure twice to supplement the quantity; in summary, the coarse sowing structure set up in the present invention is used for preliminary sowing, and when the number of discharged seeds is less than the preset value, it is supplemented by the precision sowing structure to achieve accurate sowing of seeds.

[0044] Example 2

[0045] like Figure 2-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 No. 201820274180.6, and the first containing structure and the second containing structure can be the quantitative slot structure disclosed in 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.

[0046] 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 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. The containing tank assembly 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 is a plurality of, and the plurality of containing tank assemblies are spaced apart equidistantly along the circumference of the first rotating disk 30. 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 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 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 the corresponding In the first receiving groove 31 and the second receiving groove 41, when sowing is required, the first turntable 30 is rotated by a certain angle so that the receiving groove assembly with the seeds rotates 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, three 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 the second receiving groove does not contain seeds, the second turntable can be rotated multiple times until a single seed falls from the discharge port 21.

[0047] 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. The first motor 23 and the second motor 24 are both stepper motors. 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 10 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.

[0048] 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 rotating member, and the camera 22, the first motor 23 and the second motor 24 are electrically connected to the external control system respectively. It should be noted that in this scheme, the number of seeds in the receiving tank assembly and the second receiving tank 41 is observed by the camera 22. If the number of seeds in the receiving tank assembly is too small, the first motor 23 is controlled to start first 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:

[0049] 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;

[0050] 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;

[0051] 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 based on the image;

[0052] Step S4: The control system controls the first motor 23 to start, and the first motor 81 drives the first turntable 30 to rotate the receiving tank assembly 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 tank assembly. When the system detects that seeds are missing, that is, the number of seeds is S0, S1, S2, or S3, the second motor 24 is controlled based on the missing amount to drive the second turntable 40 to rotate a set angle to rotate the second receiving tank to the discharge port 21 to supplement the missing amount of seeds.

[0053] The circuits, electronic components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
