[0027] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0028] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0029] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples. However, one skilled in the art will appreciate that the aspects described can be practiced without these specific details.

[0030] like Figure 1 and Figure 2 As shown, a handheld wheat planting sowing device of the present application includes a seed container 1 for storing wheat seeds to be sown and maintaining good fluidity to avoid accumulation of seeds in the container, which may cause interruption of the sowing process. The device is also equipped with a stirrer 2 placed inside the seed container 1 to facilitate mixing and moving the seeds in the seed container 1, preventing them from agglomerating or piling up during storage and use, and further ensuring that the seeds are in a state of easy flow throughout the storage and sowing process. In order to achieve accurate and quantitative control of the amount of wheat seeds sown in each batch, a quantitative distributor 3 is provided, which is located on the bottom surface or near the bottom of the seed container 1 and is connected to the seed container 1 and can accurately measure the wheat to be output from the container, so that continuous and proportional control of seed sowing can be achieved, thereby ensuring the stability of the sowing amount.

[0031] Then, under the device design of the present invention, the wheat seeds after quantitative distribution enter the conveying channel 4, which is also closely integrated with the aforementioned quantitative distributor 3 structure and mainly undertakes the function of transporting the measured seeds and exporting them, ensuring that the wheat measured from the quantitative distributor 3 can be smoothly and continuously transported from the inside of the sowing device to the outside. In order to avoid the situation where the sowing work cannot be completed smoothly due to blockage problems in the conveying path, the vibration component 5 is connected to the conveying channel 4 (in another embodiment, the vibration component 5 can be set on the seed container 1), and prevents the seeds from being blocked by gravity by generating periodic or continuous vibration force, so that the seeds being transported or ready to be launched outward through the device can keep moving forward continuously and uninterruptedly, thereby effectively ensuring the smooth operation of the device and the continuous and uniform sowing of wheat. Finally, the operator's gripping part, the handle component 6, is embedded in the main body of the device - specifically, it is a design structure that is closely connected to one edge of the container; this provides the operator with a convenient handheld device to support the operation of the sowing tool under the control of his hand to move along the field to perform the sowing process; at the same time, it also makes the sowing activity more comfortable and labor-saving, and shows significant advantages in improving work efficiency while reducing the labor intensity of the user.

[0032] For example, the vibration assembly 5 is typically implemented by equipping it with a motor and an eccentric shaft connected to it. The eccentric device can rotate and cause the parts associated with the vibration component to move, thereby driving the vibration and swaying movement of the entire conveying route. During operation, this system continuously creates a slight and regular mechanical vibration effect, which ensures that the seeds are always smoothly propelled forward. The mixing device is installed in the storage tank by a fixed device or drive method and usually has a spiral or other suitable design shape to help push the seed particles back and forth during rotation and prevent sedimentation and agglomeration. This combination can effectively achieve a smooth, efficient and unobstructed operation of the sowing tool. In addition, the design emphasizes the integration of humanized considerations into practical use, such as the ergonomic design of the handle component 6 to improve the user experience during long-term work. The combined effect achieves a higher-quality wheat sowing practice.

[0033] In one embodiment, reference Figure 2, the present application is a handheld sowing device for wheat planting, wherein the seed container 1 is provided with at least one inclined guide plate 7 inside, and the inclined guide plate 7 is used to improve the flow performance of the seeds in the container, ensuring that the sowing process is smoother and more efficient. Specifically, the inclined guide plate 7 can effectively change the geometric shape of the internal space of the container, so that when the seeds are filled, the seeds are guided to move along a preset path to the position of the agitator 2 with the help of the force of the inclined surface. The design of the inclined surface optimizes the traditional vertical or horizontal plane layout. It uses appropriate angle adjustment to achieve better seed fluidity without adding additional drive components, avoiding the lateral bias formed by the accumulation of seeds under the action of gravity and the possibility of clogging caused by it.

[0034] Technically speaking, a composite guide structure with a certain curvature or different inclination angles can be manufactured from suitable materials as an inclined guide plate 7, which can be installed at a specific position in the seed container 1. In actual operation, the form and distribution density of the guide plate can be fine-tuned and optimized according to factors such as the specific shape, size, and weight of the seeds to achieve the best guiding effect. In addition, in order to ensure the stability and reliability of the device during sowing operations, the method of fixing the guide plate must also be considered, and bolt tightening, snap-on locking, and other means may be used to securely place the guide assembly in the container. These improvements enable the wheat handheld sowing device to achieve efficient planting performance in various farmland conditions, significantly improving the work efficiency and economic benefits of farmers.

[0035] In one embodiment, still referring to Figure 2 , the present application is a handheld sowing device for wheat planting, the improvements of which are concentrated on the design and function of the agitator 2, which includes a plurality of spiral blades 8. The design purpose of this spiral shape is to improve the efficiency of the seed mixing and loosening process. Compared with traditional planar blades or linear structures, the spiral blades 8 can form a three-dimensional stirring effect in the seed pile due to their unique three-dimensional structure when rotating, thereby effectively loosening the wheat seed particles that are compactly stacked together due to gravity or static electricity factors, and at the same time have the ability to break up the seed clumps formed due to humidity or during transportation, significantly improving the overall stirring uniformity and sowing quality. This feature is particularly important for improving seed sowing efficiency and germination rate, because in actual farming processes, seed accumulation and adhesion often affect subsequent precise sowing operations.

[0036] In order to achieve this improved feature in the handheld sowing device from a technical level, mold forming technology can be used to construct a spiral blade structure when manufacturing the agitator 2, and the effect of stirring different varieties of wheat seeds can be further optimized by adjusting parameters such as the angle, spacing and number of layers of the spiral. For example, the pitch can be appropriately adjusted according to the size of different seeds or a variable pitch design can be adopted to better adapt to diverse working conditions and environmental requirements.

[0037] In one embodiment, Figure 3 and Figure 4 As shown, a handheld sowing device for wheat planting in the present application has a specially designed quantitative distributor 3. The quantitative distributor 3 has a lower plate structure 9, which is characterized by being composed of a plurality of small holes of uniform aperture size. This design is intended to accurately control the amount of seeds falling through the quantitative distributor 3 each time. By setting the size and shape of each aperture, it can be regulated according to the preset number of seeds, thereby ensuring the uniform distribution of seeds during the sowing process, and effectively preventing the occurrence of excessive seeds falling at one time and blocking the seed outlet. This precise and stable sowing method not only improves sowing efficiency, but also ensures the quality and consistency of crop sowing.

[0038] For example, in actual technical implementation, the lower plate can be formed by using an array of small holes with a fixed diameter and distribution pattern. The diameter of each hole should be slightly larger than the maximum cross-section of a single wheat seed to allow it to pass freely, and the hole spacing in the same row or column must ensure that a single seed or a limited number of seeds can be accurately released during each distribution process, thereby meeting the sowing needs in different environments and ensuring the operational convenience and reliability of the entire sowing device.

[0039] In one embodiment, a handheld wheat planting sowing device of the present application is specially designed with a multi-section conveying channel 4 in order to improve the smoothness of the seeds during the conveying process and reduce the blockage problem in the conveying channel 4. The interior of the multi-section conveying channel 4 contains a plurality of tubular sections 10 with different curvature radii. The design intention of this special structure is to allow the wheat seeds to smoothly pass through the various curved parts along the conveying channel 4 during the operation of the sowing device, thereby preventing the accumulation and blockage of seeds caused by the angle changes that are common in linear conveying designs. The application of the multi-section variable curvature conveying channel 4 significantly reduces the technical obstacles that the wheat planting handheld sowing device may encounter in actual use due to mechanical structural reasons, thereby enhancing the stability and sowing efficiency of the entire device during operation.

[0040] To implement these features, reasonable calculations and experiments can be used to determine the optimal configuration of curvature for each segment. Appropriate materials can then be selected and modern manufacturing processes, such as 3D printing or mold forming, can be used to create tubular components with specific combinations of curvature radii. These components can then be incorporated into handheld seeding equipment. This approach effectively ensures smooth seed delivery even around sharp or right-angle bends, while also reducing wear and extending the equipment's service life.

[0041] In one embodiment, reference Figure 2, a handheld sowing device for wheat planting in the present application includes a vibration component 5, wherein the design and construction of the vibration component 5 plays a key role in ensuring the uniformity of sowing. The vibration component 5 is composed of a group of vibration springs 11 and an electric motor 12, which realizes fine control in two dimensions of vibration frequency and amplitude. By adjusting the working state of the motor 12, the working frequency and amplitude of the vibration component 5 can be controlled, thereby ensuring that the wheat seeds entering the device maintain a moderate shaking state during the process of passing through the entire device until the final sowing. This method not only improves the planting efficiency, but also effectively avoids the problem of dense accumulation of seeds during the transportation process, which helps to further improve the uniformity of sowing and the sowing effect.

[0042] To achieve this function, the control system presets the required vibration frequency and amplitude parameters for different operating conditions, and uses a frequency converter to adjust the output frequency of motor 12. The vibration spring 11 uses different materials and specifications based on the specific operating conditions to optimize the elastic feedback effect, ensuring that the vibration process provides sufficient shaking force while maintaining good elastic recovery, thereby ensuring smooth and stable sowing of wheat seeds.

[0043] In one embodiment, reference Figure 3 , a handheld sowing device for wheat planting in the present application provides an improved technical solution to reduce or prevent the backlog of seeds on the conveying path between the seed container 1 and the quantitative distributor 3 during the sowing process. Specifically, an auxiliary cleaning component is provided between the seed container 1 and the quantitative distributor 3, which is used to monitor and clean the conveying path in time when there are signs of blockage, thereby effectively preventing the occurrence of backlogs. This technical solution helps to improve the overall operating performance and efficiency of the wheat handheld sowing device, reduce sowing discontinuity and seed waste caused by backlogs, and ensure a more stable sowing operation quality. The auxiliary cleaning component 13 can be configured to work in one of a variety of ways, for example, it can work in a timing mode or according to the real-time feedback signal provided by the pressure sensing device. In addition, the introduction of the auxiliary cleaning function is automatically triggered when the detection system recognizes changes in the internal environment of the conveying path or reaches a preset activation parameter threshold. It is crucial to enhance the reliability, durability and functionality of the handheld sowing equipment.

[0044] In practical design, this auxiliary cleaning assembly 13 can be implemented by equipping it with a small air pump or other suitable driving force source. This can periodically or when the detection system issues a backlog risk warning, inject air or vibration shock into the conveying path, thereby removing residual seed particles that are trapped or attached to the inner wall and hinder seed flow. This approach ensures the smooth operation of the entire system and its versatility in application to different types of wheat varieties.

[0045] In one embodiment, Figure 3and Figure 4 As shown, a handheld sowing device for wheat planting in the present application has an important technical feature, that is, a heat-sensitive material heating belt 14 is provided on the outside of the conveying channel 4, and the air temperature and seed temperature in the conveying channel 4 are increased by the heating effect of the heat-sensitive material heating belt 14 in a low-temperature working environment. This feature helps to avoid the condensation problem caused by the accumulation of condensed water due to temperature differences. Furthermore, heating can prevent the seeds from clumping in the conveying channel 4, ensuring the smooth operation of the device and the efficient continuation of the sowing work at any ambient temperature. Since low-temperature working conditions may cause moisture in the air to condense inside the conveying channel 4, causing the seeds to become moist, aggregated, or remain in the conveying channel 4 and difficult to flow, the presence of the heat-sensitive material heating belt 14 becomes the key to ensuring equipment reliability and work efficiency.

[0046] To achieve these characteristics, materials can be selected with consideration for their excellent heating capacity and durability. Specifically, a control unit can be used to adjust the operating state of the heat-sensitive material heating belt 14. Heat is adjusted in real time based on the external ambient temperature and data from the internal humidity sensor, ensuring that the channel maintains an appropriate temperature and humidity range. This effectively prevents condensation while also avoiding excessive drying that increases energy consumption or damages the seeds. This design makes the device highly adaptable and enables excellent sowing performance in a variety of environments.

[0047] In one embodiment, a handheld wheat planting sowing device of the present application is further improved and designed based on the existing structure, and a vibration component 5 is introduced. In order to improve the comfort of the user and the overall working efficiency of the device, an elastic shock absorption system 15 is integrated into the vibration component 5. Through this design, the problem of ground vibration caused by complex terrain being transmitted to the user can be significantly filtered and alleviated, while ensuring the smooth operation of the driving mechanism in the vibration component 5, thereby improving the sowing quality and efficiency. The addition of the elastic shock absorption system 15 can not only reduce the impact of long-term operation on the hands and wrists, but also extend the life of the entire machine by absorbing impact force and reduce the possibility of mechanical wear, providing a more stable working state for the handheld sowing equipment, and meeting the needs of various scenarios in agricultural production.

[0048] To achieve this functionality, approaches can be taken from both the perspectives of materials science and engineering. Specifically, a special material with high elastic recovery and excellent vibration damping properties can be used to create a damping module at the contact point of the vibration component 5. Alternatively, innovative structural design can be employed to physically isolate the device using springs or similar buffer structures at the joints. This significantly reduces the vibration intensity transmitted to the operator while maintaining the integrity of the device's primary functions. This technical solution can be implemented as either an integrated damping unit design or a modular combination, allowing for rapid adjustment to varying usage conditions.

[0049] In one embodiment, a wheat planting handheld sowing device of the present application, in addition to including the existing structure, is equipped with a secondary stirring component after its quantitative distributor 3 to enhance the seed processing capability. The secondary stirring component is designed to stir the seeds again quickly and lightly for a few seconds after the initial stirring. This additional operation can effectively break up the seed clumps that are easily formed in a humid environment, so that each time a sowing action is completed, fresh and scattered wheat seeds can be accurately and evenly sown into the soil. In this way, not only is the possibility of seed clumping due to high environmental humidity significantly reduced, but also the adaptability of the entire device under different meteorological conditions is improved, especially the reliability and operating effect in wet fields after rain.

[0050] To achieve this, a secondary stirring assembly consisting of one or more sets of rotating blades can be fixed at the outlet position after the quantitative distributor 3. This assembly can be driven by a motor or other power unit of the device. When the seeds pass through this assembly, the rapid rotation of the blades will break up the aggregated particles, while ensuring that the seeds are not excessively damaged during the stirring process. By finely adjusting the blade spacing and rotation speed parameters, the effect of preventing seed clumping can be achieved, and the optimal working state can be flexibly adjusted according to changes in soil texture and ambient humidity.

[0051] In actual operation, when using this device, the operator first pours wheat seeds into the seed container 1. The design of the seed container 1 ensures smooth seed flow without jamming or accumulation. Simultaneously, the agitator 2 is activated to stir the seeds inside the seed container 1, effectively preventing seed accumulation and blockage, thus ensuring that the seeds maintain excellent fluidity. The agitated seeds are precisely captured by the metered dispenser 3 and delivered in pre-set quantities into the conveying channel 4. The conveying channel 4 acts as a transport mechanism, smoothly and controlledly transporting the metered seeds to the outside world, fully preparing them for final sowing. To prevent interruptions or obstructions during the conveying process, the vibration component 5 integrates with the conveying channel 4 to assist, generating appropriate vibrations to ensure a smooth conveying process, reducing or even eliminating the possibility of seed jams at this stage. This seamless collaboration between the agitator 2 and the supporting operation of the vibration component 5 during the conveying process ensures that the wheat seeds are continuously and evenly delivered to the desired location. Throughout the entire operating cycle, the handle 6 makes transporting and operating the device in the field more convenient and comfortable. This system ensures that sowing work is carried out efficiently and stably.

[0052] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of this application.
