Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agriculture, and more specifically, to a seed screening machine for agricultural technology promotion. Background Art
[0002] After the seeds are screened, they need to be planted. Existing seed screening machines are often installed on a soil loosening device, so that the seeds can be planted while being loosened and screened at the same time.
[0003] A scarifier is a machine that uses a toothed scarifier to loosen hard soil, frozen soil, old road surface and even medium-hard rock in earthwork construction. According to the connection form of the scarifier and the tractor, there are two types: towed type and suspended type. The traction provided by the tractor and the weight of the scarifier are used to make the rake teeth cut into the soil to loosen the hard soil. A loose soil zone is left after the machine passes. It is often used for pre-loosening operations before bulldozers or scrapers operate. Compared with traditional drilling and blasting construction methods, it has the advantages of simplified construction process, reduced construction machinery and equipment, high productivity and good production safety. It is the main preparatory operation machine for earthwork construction.
