The tilting frame 23 is installed at one end of the support frame 12, and its tilted structure provides a suitable installation angle for the feed hopper 24, allowing the feed hopper 24 to smoothly introduce grass seeds into the grading and screening cylinder 16, and also facilitating the operation of feeding by operators next to the device. The feed hopper 24 is mounted on the tilting frame 23.

[0028] The feed hopper 24 is mounted on the inclined frame 23. Its shape is typically wider at the top and narrower at the bottom, facilitating the centralized pouring of large quantities of grass seeds to be screened. The grass seeds are guided along the inclined hopper wall and accurately enter the grading and screening cylinder 16 through the feed hole, simplifying the feeding process and improving feeding efficiency. A sorting container 25 is located at the bottom of the grading and screening cylinder 16. The sorting container 25 is connected to the bottom of the grading and screening cylinder 16 and is used to collect grass seeds falling from different apertures of the grading and screening cylinder 16, concentrating the initially screened grass seeds for further classification and processing.

[0029] The sorting container 25 has a receiving cavity, which provides installation space for multiple sets of sorting dividers 26. This allows for further sorting and storage of grass seeds of different sizes within the sorting container 25, providing a basic framework for grass seed classification. Multiple sets of sorting dividers 26 are installed within the receiving cavity of the sorting container 25. These dividers subdivide the receiving cavity, with each divider 26 capable of storing grass seeds of a specific size, thus achieving further classification of the grass seeds. Both the multiple sets of sorting dividers 26 and the sorting container 25 have discharge holes, facilitating the flow of grass seeds from the sorting dividers 26 and the sorting container 25 for subsequent collection and processing.

[0030] Each of the multiple sorting compartments 26 and the sorting container 25 has a filter screen at one end. This filter screen allows for secondary screening of the grass seeds, further filtering out any remaining impurities. Each of the multiple filter screens has a secondary screening box 27 located at the bottom of the grading and screening cylinder 16. This secondary screening box collects impurities and unsuitable grass seeds falling from the filter screens, further improving the purity of the grass seeds. The instrument support frame 11 has multiple outlet ends 28. One end of each outlet end 28 is connected to the sorting container 25, providing an outlet channel for the screened and sorted grass seeds. This facilitates guiding grass seeds of different sizes to the collection boxes 31 on different collection supports 29, achieving final collection of the grass seeds.

[0031] A collection bracket 29 is provided on the instrument support frame 11. The collection bracket 29, mounted on the instrument support frame 11, provides support and positioning for multiple collection boxes 31, ensuring that the collection boxes 31 can be stably placed in a suitable position to collect the grass seeds flowing out from the outlet end 28. Multiple collection boxes 31 are placed on the collection bracket 29 to collect grass seeds of different specifications after screening and sorting, facilitating subsequent processing and use by the user. Multiple anti-slip pads 32 are provided at the bottom of the instrument support frame 11. The anti-slip pads 32, installed at the bottom of the instrument support frame 11, increase the friction between the instrument support frame 11 and the ground, preventing the device from sliding due to vibration or external forces during operation, ensuring the stability of the device during operation, and guaranteeing the smooth progress of the entire screening process.

[0032] like Figures 2 to 4 As shown, when using this device, the user first places the instrument support frame 11 in a suitable working area.

A placement plate 13 is provided on one side of the instrument support frame 11. The placement plate 13 provides a dedicated mounting position for the motor 19. The user places the motor 19 stably on the placement plate 13. The motor 19 serves as the power source for the device, and its shaft end is connected to one end of the drive shaft 17 via a belt. After starting the motor 19, the power is transmitted to the drive shaft 17 via the belt, thereby driving the screening components to operate, ensuring the smooth operation of the entire sorting process. A fixed bearing plate 14 is provided on one side of the support frame 12. The fixed bearing plate 14 is securely connected to the support frame 12 by bolts, providing support and positioning for the drive shaft 17. This ensures that the drive shaft 17 can stably pass through it and rotate smoothly under the drive of the motor 19, thereby driving the grading and screening cylinder 16 to operate efficiently. A protective shell 15 is provided on the support frame 12. The protective shell 15 is installed on the support frame 12 and encloses the screening components. On the one hand, it prevents external dust, debris, etc. from entering the screening components and affecting the sorting effect of grass seeds; on the other hand, it protects the operators from accidental contact with the high-speed rotating parts inside, ensuring operational safety.

[0033] The protective housing 15 is equipped with a screening assembly for preliminary screening, which includes a grading sieve cylinder 16. One end of the grading sieve cylinder 16 is connected to the protective housing 15 by a fixing bolt, and the other end is secured to the instrument support frame 11, ensuring the stability of the grading sieve cylinder 16. The aperture of the grading sieve cylinder 16 gradually increases along the transport direction, and both ends are equipped with caps 21. One set of caps has a feed hole, which allows the user to pour in the wild grass seeds to be sorted; the other set of caps is fitted onto the drive shaft 17, further securing the connection between the grading sieve cylinder 16 and the drive shaft 17. When the drive shaft 17 rotates, it drives the grading sieve cylinder 16 to rotate, and the grass seeds tumble inside the cylinder, falling from different apertures according to their particle size, thus achieving preliminary screening. The drive shaft 17 passes through the fixed bearing plate 14, and a push rotating frame 18 is fitted onto the drive shaft 17. The rotating frame 18 is located inside the grading and screening cylinder 16 and rotates with the drive shaft 17. It continuously pushes the grass seeds inside the grading and screening cylinder 16, making them evenly distributed and moving them in a specific direction, thereby improving the screening effect.

[0034] One end of the support frame 12 is equipped with an inclined frame 23, on which a feeding hopper 24 is mounted. The feeding hopper 24, wider at the top and narrower at the bottom, facilitates the concentrated pouring of large quantities of grass seeds to be screened and guides the grass seeds along the inclined hopper wall into the grading and screening cylinder 16 through the feeding hole, simplifying the feeding process and improving feeding efficiency. A sorting container 25 is located at the bottom of the grading and screening cylinder 16, connected to the cylinder, and used to collect grass seeds falling from different apertures within the cylinder. The sorting container 25 has a receiving cavity, on which multiple sets of sorting dividers 26 are mounted. These dividers 26 are engaged with the sorting container 25, further subdividing the receiving cavity and enabling further sorting of the grass seeds. Both the multiple sets of sorting dividers 26 and the sorting container 25 have discharge holes for easy grass seed discharge. Each of the multiple sorting compartments 26 and the sorting container 25 has a filter screen at one end, and each of the multiple filter screens has a secondary screening box 27. The secondary screening box 27 is located at the bottom of the grading and screening cylinder 16, and can perform secondary screening of grass seeds to filter out residual impurities and improve the purity of grass seeds.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When using the device, the user first places the instrument support frame 11 on a stable surface to provide solid support for the device. The support frame 12 is then installed on the instrument support frame 11, supporting other key components. The motor 19 is placed on the placement plate 13 on one side of the instrument support frame 11, and its shaft is connected to the drive shaft 17 via a belt. A fixed bearing plate 14 is connected to one side of the support frame 12, through which the drive shaft 17 passes. The protective housing 15 on the support frame 12 encloses the screening components, ensuring safe operation and effective screening. The grass seeds to be sorted are poured into the feed hopper 24 on the inclined frame 23. The grass seeds enter the grading and screening cylinder 16 through the feed hole on one end of the cap 21. The motor 19 drives the drive shaft 17, causing the grading and screening cylinder 16 and the push rotating frame 18 located inside the cylinder to rotate. The grass seeds continuously tumble inside the cylinder and fall from different apertures of the grading and screening cylinder 16 according to their particle size, landing in the sorting container 25 connected to the bottom. The sorting container 25 contains multiple sets of sorting dividers 26 for further subdivision of grass seeds. The discharge holes on the sorting dividers 26 and the sorting container 25 facilitate the flow of grass seeds, while the filter screens and secondary screening boxes 27 at one end can perform secondary screening of grass seeds to improve their purity.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
