Description

Technical Field

[0001] This invention belongs to the field of sowing device technology, specifically, it relates to a precision hill-sowing device for sesame. Background Technology

[0002] Sesame is an important specialty oil crop in my country, with a wide planting range. The precision, depth, and efficiency of sowing directly affect the sesame seedling emergence rate, plant growth, and final yield, which is of great significance to the economic benefits of growers and the development of mechanized sesame planting technology.

[0003] With the development of agricultural modernization, traditional sowing methods can no longer meet the needs of large-scale sesame planting. The few sesame sowing devices currently on the market also have many defects: most devices rely on additional power to drive the seed metering components, which not only have a complex structure, high energy consumption, and heavy weight, but also increase manufacturing costs and the probability of failure, which is not conducive to flexible field operations.

[0004] Some seeding devices with quantitative functions do not adopt a closed-loop detection and control method, which makes it impossible to identify, mark and selectively discharge the amount of seeds in a single hole in real time. This can easily lead to problems such as multiple rows, missed rows, and incorrect rows. Overall, the devices lack versatility, practicality and operational precision, which restricts the further improvement of the mechanization and precision of sesame planting. Summary of the Invention

[0005] (a) Technical problems to be solved The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a sesame hole-sowing precision sowing device that is simple in structure, requires no additional power, sows accurately, and is easy to operate.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a sesame precision hill-planting device, including a support frame, and further comprising: The hopper is fixedly connected to the bracket; A seeding box is fixedly connected to the bottom of the hopper, and the seeding box is used to dispense seeds from the hopper. A seed inlet hopper is fixedly connected below the hopper and is used to collect the seeds dispensed from the seed box. A seed dispenser is installed inside the seed inlet hopper, and the seed dispenser is used to collect and quantitatively discharge the seeds inside the seed inlet hopper.

[0007] Furthermore, the seed dispenser is provided with multiple seed inlets arranged in a ring shape, which are used to store seeds. A fan-shaped baffle is rotatably connected to the seed dispenser, which is used to block part of the seed inlets, thereby preventing seeds from entering the seed inlets. Multiple detection sensors are arranged in a ring shape on the baffle. A solenoid valve is installed at the bottom of the seed inlet. The detection sensors are used to detect the seed height in the seed inlet. When the seed height reaches the standard, the solenoid valve opens, thereby accurately discharging a certain amount of seeds.

[0008] Furthermore, a telescopic rod is fixedly connected inside the seed inlet hopper, and multiple sets of top rods are fixedly connected to the telescopic end of the telescopic rod. The top rods are slidably connected inside the seed inlet, and the solenoid valve is fixedly connected to the top rods.

[0009] Furthermore, a lifting plate with a perforated hole is fixedly connected to the telescopic end of the telescopic rod. The diameter of the perforated hole is larger than the diameter of the seed, and the top rod is fixedly connected to the lifting plate.

[0010] Furthermore, the seeding box has a circular placement groove, and the top and bottom of the placement groove are provided with connection ports, which are respectively connected to the hopper and the seed inlet hopper. A seeding gear is rotatably connected in the placement groove. The seeding gear is used to quantitatively dispense the seeds from the hopper and then let them enter the seed inlet hopper below.

[0011] Furthermore, two sets of rollers are rotatably connected to the bracket, and a rotating rod is mounted on the roller. The other end of the rotating rod is fixedly connected to the sowing gear.

[0012] Furthermore, a chain drive assembly is installed on the bracket, wherein a set of rollers is engaged with the chain drive assembly, and the rotating rod is fixedly connected to the rotating end of the chain drive assembly.

[0013] Furthermore, a screen is fixedly connected inside the hopper, which divides the hopper into two chambers. The screen is used to screen the seeds entering the hopper, and the connection port above the seeding box communicates with the chamber below the hopper.

[0014] Furthermore, a detachable seed outlet pipe is installed at the bottom of the seed inlet hopper.

[0015] Furthermore, a servo motor is fixedly connected inside the seed generator, and a rotating shaft is fixedly connected to the output end of the servo motor. The baffle is fixedly connected to the rotating shaft.

[0016] (III) Beneficial Effects After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the present invention solves the common industry problems of sesame seeds being small in size, irregular in shape, poor in flowability, easy to get stuck, and easy to miss when sowing; The device uses a ring-shaped seed inlet combined with an intermittently rotating baffle structure, along with the fixed-point detection and standard marking functions of the detection sensor. It can achieve accurate quantitative storage and identification of irregularly shaped sesame seeds, avoiding uneven filling and inaccurate counting caused by irregular seed shapes, and ensuring a stable and consistent number of seeds per hole. The seed inlet is equipped with a sliding top rod structure that can actively push the seeds in and out smoothly, effectively overcoming the defects such as jamming, residue, and poor seed discharge caused by the irregular shape of sesame seeds, making the seed discharge process smoother and more reliable. The device achieves pure mechanical linkage seed supply through the walking wheels and chain drive components, without the need for additional power drive. The structure is simpler, the operation is more stable, and the energy consumption is lower. At the same time, in conjunction with the screen structure in the hopper, shriveled, broken and impurities can be screened out in advance, further improving the purity of seeds and the uniformity of seedling emergence. The bottom of the seed inlet hopper features a detachable seed outlet tube, allowing for flexible adjustment of the sowing depth according to agronomic needs, thus enhancing the device's adaptability and ease of use. The integrated device realizes the integrated operation of sesame seed screening, seed supply, quantitative measurement, detection, marking and precise discharge, which greatly improves the sowing accuracy and operation efficiency, reduces labor costs and equipment failure rate. It is especially suitable for hole sowing of small and irregular seeds, and can significantly improve the germination rate and sowing uniformity. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Example: Refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 A precision sesame seeding device includes a support frame 1, and further includes: Hopper 2 is fixedly connected to bracket 1; The seeding box 4 is fixedly connected to the bottom of the hopper 2. The seeding box 4 is used to dispense the seeds from the hopper 2. The seed inlet hopper 5 is fixedly connected to the bottom of the hopper 2. The seed inlet hopper 5 is used to collect the seeds dispensed from the seed box 4. The seed dispenser 6 is installed inside the seed inlet hopper 5. The seed dispenser 6 is used to collect and quantitatively discharge the seeds inside the seed inlet hopper 5.

[0021] like Figure 6 , Figure 7 As shown, the seed dispenser 6 has multiple seed inlets 601 arranged in a ring. The seed inlets 601 are used to store seeds. A fan-shaped baffle 604 is rotatably connected to the seed dispenser 6. The baffle 604 is used to block part of the seed inlets 601, so that seeds cannot enter the seed inlets 601. Multiple detection sensors 605 are arranged in a ring on the baffle 604. A solenoid valve 704 is installed at the bottom of the seed inlet 601. The detection sensor 605 is used to detect the seed height in the seed inlet 601. Once the seed height reaches the standard, the solenoid valve 704 opens, thereby accurately discharging a fixed amount of seeds.

[0022] like Figure 5 , Figure 6 As shown, a telescopic rod 701 is fixedly connected inside the seed inlet 5. Multiple sets of top rods 703 are fixedly connected to the telescopic end of the telescopic rod 701. The top rods 703 are slidably connected inside the seed inlet 601, and the solenoid valve 704 is fixedly connected to the top rods 703.

[0023] A lifting plate 702 with a hollow hole is fixedly connected to the telescopic end of the telescopic rod 701. The diameter of the hollow hole is larger than the diameter of the seed. The top rod 703 is fixedly connected to the lifting plate 702.

[0024] like Figure 5 As shown, the seeding box 4 has a circular placement groove. The top and bottom of the placement groove are provided with connection ports for connecting to the hopper 2 and the seed inlet hopper 5, respectively. A seeding gear 401 is rotatably connected inside the placement groove. The seeding gear 401 is used to quantitatively dispense the seeds from the hopper 2 and then let them enter the seed inlet hopper 5 below.

[0025] Two sets of rollers 301 are rotatably connected to the bracket 1. A rotating rod 303 is installed on the rollers 301, and the other end of the rotating rod 303 is fixedly connected to the sowing gear 401.

[0026] like Figure 2 As shown, a chain drive assembly 302 is installed on the bracket 1, in which a set of rollers 301 are engaged with the chain drive assembly 302, and a rotating rod 303 is fixedly connected to the rotating end of the chain drive assembly 302.

[0027] A screen 201 is fixedly connected inside the hopper 2. The screen 201 divides the hopper 2 into two chambers. The screen 201 is used to screen the seeds entering the hopper 2. The connection port above the seeding box 4 is connected to the chamber below the hopper 2.

[0028] The bottom of the seed inlet hopper 5 is detachably equipped with a vertical seed outlet tube 8 with a length of 1 to 2 cm, which can extend into the soil 1 to 2 cm. The rollers 301 at the bottom of the support 1 support the height of the whole machine, so that the lower end of the seed outlet tube 8 maintains a constant distance from the ground, and the seeds fall into the soil in a vertical direction, thereby stably controlling the sowing depth within the range of 1 to 2 cm.

[0029] A servo motor 602 is fixedly connected inside the seed generator 6, and a rotating shaft 603 is fixedly connected to the output end of the servo motor 602. The baffle 604 is fixedly connected to the rotating shaft 603.

[0030] The specific steps for using this device are as follows: Step 1: Seed pretreatment and feeding The operator first performs preliminary manual screening of the sesame seeds to remove obvious impurities, stones, broken grains, and moldy seeds, thereby improving the purity of the seeds and preventing impurities from entering the device and causing problems such as jamming and wear. After screening, the plump and qualified sesame seeds are slowly poured into hopper 2. The pouring speed must be controlled during the pouring process to prevent the seeds from accumulating too quickly and causing blockage in the lower chamber of hopper 2.

[0031] Step 2: Parameter Presetting and Component Debugging After the seeds are fed, the operator needs to input a preset threshold for the number of seeds per hole into the digital display control module of the device, based on the local agronomic requirements and target sowing density for sesame cultivation. This threshold will be synchronously transmitted to the judgment logic of the detection sensor 605 on the baffle 604 to ensure that the detection sensor 605 can accurately identify whether the seeds in the seed inlet 601 have reached the quantitative standard. At the same time, the operator sets the rotation and pause parameters of the baffle 604 and the number of seed inlets 601 for single seed discharge in the digital display control module (one or more can be set according to sowing needs) to complete the parameter preset for standard marking and quantitative discharge. After the parameter preset is completed, the operator focuses on debugging the core moving parts and electrical control parts of the device: first, adjust the initial stroke of the telescopic rod 701 through the digital display. The control module controls the telescopic rod 701 to be in a fully retracted state, which in turn drives the lifting plate 702 and the multiple sets of top rods 703 fixed on the lifting plate 702 to the initial low position. At this time, the top of the top rod 703 is flush with the bottom of the seed inlet 601. At the same time, it ensures that the solenoid valve 704 fixed on the top rod 703 is in a fully closed state to prevent the seeds from leaking out in advance and to prepare for the quantitative storage of the seeds. Next, check the connection status between the seed outlet tube 8 and the bottom of the seed inlet hopper 5. The seed outlet tube 8 adopts a detachable threaded connection. The operator needs to tighten the seed outlet tube 8 by hand to ensure that there is no looseness or gaps at the connection. At the same time, check whether the tube body of the seed outlet tube 8 is unobstructed and whether there are any bends or blockages, so as to ensure that the quantitative seeds can fall smoothly and accurately into the soil at the preset depth. Finally, check the tension of the chain drive assembly 302. This chain drive assembly 302 consists of three sets of gears (one set of driving gears and two sets of driven gears) and two chains. The driving gear meshes with one set of rollers 301. The two sets of driven gears are connected to the rotating rod 303 and the auxiliary transmission components of the device, respectively. The two chains are respectively mounted on the driving gear and the first set of driven gears, and the first set of driven gears and the second set of driven gears. The operator needs to manually rotate the chain to check for any looseness or detachment. If the chain is too loose, it can be tightened by adjusting the gear adjustment seat on the adjustment bracket 1. If the chain is too tight, the adjustment seat can be loosened appropriately to ensure tight meshing between the gears and the chain, smooth power transmission, and to avoid chain slippage or detachment in subsequent operations. This ensures the stability and synchronization of power transmission. During the debugging process, if any abnormality is found in a certain component, the machine must be stopped immediately for processing. It is strictly forbidden to carry out subsequent operations with a faulty component.

[0032] Step 3: Depth Setting and Overall Inspection According to the local agronomic requirements for sesame cultivation (the sowing depth of sesame varies depending on the region and soil moisture, generally 1-2 cm), the effective length of the seed outlet tube 8 is adjusted to achieve precise control of the sowing depth. If a shallower sowing depth is required, a shorter seed outlet tube 8 can be used; if a deeper sowing depth is required, a longer seed outlet tube 8 can be used. During the replacement process, it is necessary to ensure that the seed outlet tube 8 is firmly connected to the bottom of the seed inlet hopper 5. After the seed outlet tube 8 is adjusted, the device is inspected as follows: check the structural stability of the support 1 to ensure that the support 1 is not deformed or loose and can stably bear the weight of each component; check the rotational flexibility of the roller 301 by pushing the roller 301 to roll freely and observing whether there is any jamming or abnormal noise. If any abnormality is found, the bearing of the roller 301 needs to be checked. If any damage occurs, replace or add lubricating oil promptly. Check the wiring connections of electrical control components such as servo motor 602 and telescopic rod 701 to ensure that the wiring connections are secure, undamaged, and free from leakage risks. Ensure that the display screen of the digital control module can display parameters normally and that the detection sensor 605 is working properly. Check the rotation flexibility of the sowing gear 401 inside the sowing box 4. Manually rotate the sowing gear 401 to observe whether the gear rotates smoothly and whether there is any damage or deformation in the tooth grooves. Ensure that the sowing gear 401 can properly scoop and dispense seeds. After the overall inspection is completed, start the device for a 1-2 minute no-load test run, focusing on testing the rotation and pause of the baffle 604, as well as the detection sensitivity and compliance marking function of the detection sensor 605. After confirming that there are no abnormalities, the field sowing operation can begin.

[0033] Field sowing operation stage.

[0034] Step 1: Device Movement and Power Linkage The operator pushes the handle of the support 1 or uses a traction device to pull the support 1, causing the two sets of rollers 301 at the bottom of the support 1 to roll smoothly along the field surface. The device begins to move along the preset sowing route. During the rolling of the rollers 301, one set of rollers 301, which is meshed with the chain drive assembly 302, synchronously drives the drive gear of the chain drive assembly 302 to rotate. The drive gear drives the first set of driven gears to rotate through the first chain. The first set of driven gears then drives the second set of driven gears to rotate through the second chain. Finally, the second set of driven gears drives the rotating rod 303 to rotate synchronously. Since the other end of the rotating rod 303 is fixedly connected to the sowing gear 401 inside the sowing box 4, the rotation of the rotating rod 303 will drive the sowing gear 401 inside the sowing box 4 to rotate at a uniform speed. The seeding gear 401 rotates 400 degrees. The placement slot inside the seeding box 4 is circular. The top and bottom connection ports are connected to the chamber below the hopper 2 and the seed inlet hopper 5, respectively. The tooth groove of the seeding gear 401 can accurately scoop up the seeds in the chamber below the hopper 2. As the seeding gear 401 continues to rotate, when the tooth groove rotates to the connection port at the bottom of the seeding box 4, the seeds in the tooth groove fall smoothly into the seed inlet hopper 5 below under the action of gravity, realizing a continuous and quantitative supply of seeds. The entire power transmission process does not require an additional power source. It relies entirely on the rotation of the roller 301 during the movement of the device to provide power, which simplifies the device structure and reduces energy consumption. At the same time, the rotation speed of the seeding gear 401 is precisely matched with the movement speed of the device, which can effectively ensure the uniformity of the plant spacing in the field and avoid the problem of excessively dense or sparse plant spacing.

[0035] Step 2: Quantitative storage and precise testing of seeds Seeds falling from the seed box 4 into the seed hopper 5 gather towards the seed dispenser 6 at the bottom of the seed hopper 5 under the influence of gravity. At this time, the servo motor 602 inside the seed dispenser 6 starts, driving the rotating shaft 603 to slowly rotate the baffle 604. The fan-shaped structure of the baffle 604 continuously blocks part of the seed inlet 601, leaving only the unblocked seed inlet 601 open to receive seeds falling from the seed hopper 5 (the unblocked seed inlet 601 is not effectively detected by the detection sensor 605, and the seed quantity cannot be determined). When the baffle 604 rotates to the preset position, the servo motor 602 stops working, and the baffle 604 pauses intermittently. At this time, the multiple sets of detection sensors 605 on the baffle 604 will align with the seed inlets 601 below one by one (only at this time can the detection sensors 605 accurately align with the seed inlets 601 to carry out detection work), and perform seed height detection on the seed inlets 601 that have received seeds. The detection sensors 605 adopt high-precision photoelectric sensors, which can accurately detect the seed height. The system identifies the seed stacking height and transmits the detected height data to the digital display control module in real time. The digital display control module compares the received real-time height data with the height data corresponding to the preset single-hole seed quantity threshold. When the seed height in a seed inlet 601 reaches the preset threshold, it indicates that the seed quantity in that seed inlet 601 has reached the quantitative standard for single-hole sowing. The digital display control module immediately marks the qualified seed inlet 601 and stores the marking information. If the seed height in a seed inlet 601 does not reach the preset threshold, the seed inlet 601 will not be marked and will remain open. After the baffle 604 rotates and resets, it will continue to receive seeds until the standard is reached. After the detection is completed, the servo motor 602 starts again, driving the baffle 604 to continue to rotate slowly, entering the next round of seeding, pausing, detection, and marking cycle, ensuring the continuity of the sowing operation, and ensuring that multiple seed inlets 601 can complete the quantitative storage and standard marking of seeds in an orderly manner.

[0036] Step 3: Precisely Discharge Quantitative Seeds As the baffle 604 continues to rotate with the detection sensor 605 after the detection is completed, until the seed inlet 601 marked as "qualified" rotates to the seed outlet position below the baffle 604 (this position is precisely aligned with the seed outlet channel at the bottom of the seed inlet hopper 5 and is the only position where seeds can be discharged), the servo motor 602 pauses again to ensure that the qualified seed inlet 601 is stably in the seed outlet position. At this time, the digital display control module will trigger the corresponding number (one or more) of solenoid valves 704 at the bottom of the qualified seed inlets 601 according to the previously preset discharge quantity requirements. After receiving the control signal, the solenoid valve 704 immediately opens. Under the action of gravity, the seeds fall to the bottom of the seed inlet hopper 5 through the open solenoid valve 704, and then fall precisely into the soil at the preset depth through the seed outlet pipe 8 at the bottom of the seed inlet hopper 5, completing a quantitative and deep hole sowing operation. The solenoid valve 704 of the seed inlet 601 that is not marked as "qualified" remains closed, regardless of whether it is in other positions. The seeds will continue to remain in the seed inlet 601 until the subsequent baffle 604 rotates, pauses to detect qualified seeds and marks them, and then they are transferred to the seed outlet position for discharge.

[0037] Step 4: Cyclic Seeding and Abnormal Handling After a single-hole sowing operation is completed, the opened solenoid valve 704 closes to prevent subsequent seeds from leaking out prematurely. Simultaneously, the digital display control module clears the qualifying mark from the seed inlet 601, allowing it to enter the next round of sowing and detection cycles. Subsequently, the servo motor 602 continues to drive the rotating shaft 603 and baffle 604 to rotate, moving the seed inlet 601 that has completed seeding to a position where seeds do not fall or exit. At the same time, the next set of undetected or qualified but not yet discharged seed inlets 601 are moved to their corresponding positions, continuing the operations of sowing, pausing detection, marking qualifying seeds, and discharging seeds. As the device continues to move, the roller 301, chain drive assembly 302, and sowing gear 401 continuously work together, cycling through the steps of seed dispensing, quantitative storage, detection marking, and precise discharge, achieving continuous and precise hole sowing operations in the field. During the cyclical sowing process, the operator must monitor the device's operating status throughout. If the digital display control module indicates a fault in the detection sensor 605, the machine must be stopped immediately. Wipe the detection end of the detection sensor 605 with a dry, soft cloth to remove dust and seed residue from the surface. Readjust the alignment accuracy between the sensor and the seed inlet 601, and continue operation only after confirming that it is correct. If the chain drive assembly 302 is found to be slipping or making abnormal noises, the machine must be stopped to check the chain tension and gear meshing status, and adjust or add lubricating oil as needed. If the seed outlet tube 8 is found to be blocked, the machine must be stopped to disassemble the seed outlet tube 8, clean the seed residue inside the tube, and ensure that the seed outlet tube 8 is unobstructed before reinstalling it for use. If seeds are found to be accumulating in the seed inlet hopper 5 and the seed outlet 6, the machine must be stopped to clean them to avoid blockage and affecting work efficiency. If the rotation and pause actions of the baffle 604 are found to be abnormal, the operating status of the servo motor 602 must be checked, and the rotation and pause parameters must be adjusted to ensure that the detection sensor 605 can accurately align with the seed inlet 601 for detection.

[0038] In addition, if it is necessary to adjust the sowing density, the operator can modify the preset threshold for the number of seeds per hole through the digital display control module, and at the same time adjust the rotation speed of the baffle 604, the pause time, and the number of qualified seed inlets 601 discharged at one time, so as to achieve the adaptation of different sowing densities without the need for large-scale disassembly and adjustment of the device. It is convenient to operate and highly adaptable.

[0039] (III) Operation Completion and Equipment Maintenance Phase After field sowing is completed, the equipment needs to be cleaned, maintained, and serviced promptly. The core purpose is to remove seed residue and impurities from the equipment, check the wear and tear of each component, extend the service life of the equipment, and ensure that the equipment can be put into normal use next time. The specific steps are as follows: Step 1: Clear away any remaining seeds The operator first turns off all power switches of the device and cuts off the power supply to the electrical control components to avoid safety hazards such as electric shock and accidental equipment start-up during maintenance. Then, the operator opens the feed inlet at the top of hopper 2 and cleans the shriveled seeds and impurities trapped by screen 201 in the upper chamber of hopper 2 by hand or with a special tool. Then, the operator removes screen 201 from hopper 2 and cleans the residual seeds and impurities on the surface of screen 201. After cleaning, screen 201 is reinstalled in hopper 2. Next, the operator tilts the bracket 1 to allow the residual seeds in the lower chamber of hopper 2 to fall into the seed feed hopper 5. Next, open the cleaning door on the side of the seed inlet 5, start the servo motor 602, drive the baffle 604 to rotate, and rotate all the seed inlets 601 to the cleaning position one by one. Open all the solenoid valves 704 to clean out all the residual seeds in the seed inlet 5, seed outlet 6 and each seed inlet 601, and collect them into a special container to prevent the seeds from remaining inside the device to mold and clump, affecting the next sowing operation, and also to avoid seed waste. During the cleaning process, be careful to move gently to avoid damaging small parts such as the screen 201, seed inlet 601, and detection sensor 605.

[0040] Step 2: Clean equipment parts After cleaning up the residual seeds, disassemble the seed outlet tube 8 at the bottom of the seed inlet hopper 5, rinse the inside of the seed outlet tube 8 with clean water, and remove the seed residue and soil inside the tube.

[0041] Step 3: Maintenance and Care After cleaning the equipment components, the focus is on maintaining and servicing the moving parts and electrical control components of the device: First, maintain the gears and chains of the chain drive assembly 302; then, conduct dust and moisture protection checks on electrical control components such as the telescopic rod 701 and servo motor 602, check whether the wiring connections are secure, and whether there is any damage or aging. If any wiring damage is found, it must be replaced in time to ensure that the device can operate normally when it is put into use next time.
