It was learned from Zhengzhou Grain Wholesale Market that the research team led by Qiao Jihua, chairman and general manager of Qinghai Province Jiangheyuan Agriculture and Animal Husbandry Technology Co., Ltd., successfully developed the first “grass no-till seeding machine†in China after more than one year of trials.
The forage seeding machine is composed of a seed box, a seeding needle, a seeding tube, a lifting frame and the like. Trapped by a 20 hp tractor, the seeding tube on the circumference of the seed box and the seeding needle at the end thereof are rotated, and the grass seed and fertilizer mixture in the seed box enters the seeding needle through the seeding tube, and the needle is retracted when the seeding needle is inserted into the ground. The seed room is opened, and the grass seeds and fertilizers flow into the soil with the quantitative flow of the guide trough into the needle. When the seed box continues to rotate, the seeding needle leaves the ground, the needle is reset, the seed chamber is closed, and then the grass seeding machine is covered with a soil ring to complete the planting. The planter is equipped with a hydraulic automatic lifting device, and the seeding needle automatically adjusts the length of the needle according to the ground condition, which can adapt to uneven grassland.
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
