[0002] Fowl's tail grass, also known as wolfsbane, is an ornamental perennial herb belonging to the genus *Lolium* of the Poaceae family. Its scientific name is *Lolium perenne*. Native to Europe and Asia, it is now widely distributed globally. Its stems are erect, reaching a height of 30-120 cm. Its leaves are narrow and pointed, dark green, and its inflorescence is a spike-like inflorescence with numerous small flower spikes. Fowl's tail grass thrives in sunny, moist soil and is commonly found in grasslands, pastures, and parks. It is an important forage plant, widely used in lawns, golf courses, and grass sports fields. In addition, Napier grass also has certain medicinal value and can be used to treat diseases such as rheumatism and arthritis. When collecting Napier grass seeds, the seeds are often mixed with some petals, stamens, stem and leaf fragments, and dust, which affects the purity and quality of the seeds.

[0013] Working Principle: When using this device, first fill the recycling tank with water, then start the water pump inside the tank. The water is pumped into the power pipe and flows into the upper part of the screening frame. Because the screen is tilted forward, the water flows out through the collection trough and the outlet at the bottom front, then falls into the return water frame. After being filtered by the filter frame, it flows back into the recycling tank, thus forming a water cycle. At this point, seeds mixed with impurities, such as Napier grass seeds, can be placed into the screening frame. When the seeds enter the frame, the drive motor is activated, causing the turning roller to rotate, stirring the seeds. Flower stamens, stem and leaf fragments, and bad seeds mixed in will float to the surface and fall into the impurity frame through the collection trough. Simultaneously, some dust will dissolve into the water. Some denser sand and gravel will sink to the bottom of the water. Then, the sand, gravel, and seeds will fall onto the drain conveyor belt along with the water flow and the conveyor plate. At this time, some sand, gravel, and water that have not settled into the screening frame and smaller in volume will fall into the return water frame. At the same time, the fan is started and the seeds on the drain conveyor belt are dried through the first air pipe and the drying nozzle. The air is heated by the heating plate when it passes through the first air pipe, which improves the drying efficiency. Then, the seeds will fall from the drain conveyor belt into the air collection frame and be blown by the air to the lower frame to enter the collection mechanism. After the seeds fall into the feed cylinder, the fan inside the waterproof frame is started. At this time, the air will be blown into the seed collection frame from the feed cylinder through the air outlet pipe. During the upward blowing, the seeds will be further dried. Finally, the seeds fall into the seed collection frame and the collection is completed.
[0014] (III) Beneficial Effects This invention provides a seed collection device with a screening function. It has the following beneficial effects: 1. This invention provides a seed collection device with a screening function. The device has an internal screening mechanism. When the seeds of Napier grass are placed in the device, water flows smoothly from the inside of the power pipe to the top of the sorting frame through the water pump system. Due to the forward inclination of the water flow inside the sorting frame, the accumulated water flows through the collection tank and the outlet at the lower front end into the inside of the return water frame. Then, under the action of the filter frame, it enters the inside of the recycling water tank to form the recycling of water source. As a result, the stamens, stem and leaf fragments and bad seeds mixed in with the seeds will float on the water surface and gather inside the collection tank. At the same time, some dust will dissolve into the water, while some denser sand and gravel will sink to the bottom. Next, the sand and gravel and seeds will fall onto the drain conveyor belt with the water flow and the conveyor plate, realizing the automatic separation of impurities, effectively saving labor and improving work efficiency.
[0015] 2. This invention provides a seed collection device with a screening function. After the seed screening process is completed, a fan is started and uses the first air duct as a path to air dry the seeds exposed to the drying nozzle. During this process, the air duct is heated by a heating plate, which improves the drying efficiency. Then, the seeds fall from the surface of the dewatering conveyor belt, are blown into the air collection frame, and finally fall into the inside of the feeding cylinder. Subsequently, the fan in the waterproof frame is started, and the air blows from the air outlet duct into the inside of the feeding cylinder and moves upward along the surface of the air duct. At the same time, the rotary motor is started to drive the rotating cylinder to rotate, which will further promote the turning and drying of the seeds. Finally, the seeds fall into the seed collection frame to complete the collection, thus further improving the collection efficiency of this collection device. Attached Figure Description
