Improved stubble-land zero-tillage straw-covering precision planter

Abstract

The invention discloses an improved stubble-land zero-tillage straw-covering precision planter. The improved stubble-land zero-tillage straw-covering precision planter comprises a straw-cleaning device assembly. A straw-cleaning cutter shaft is internally provided with a bearing, and the straw-cleaning cutter shaft is protruded out of the end part of a machine frame and is successively provided with a first fixing structure component and a second fixing structure component from inside to outside. The straw-cleaning cutter shaft is provided with a chain. The improved stubble-land zero-tillage straw-covering precision planter is characterized by further comprising a solid cylindrical long rod. The bearing is installed at the periphery of the solid cylindrical long rod, and an outer circumferential position of the bearing is provided with a sleeve. The sleeve is protruded out of the outer side of the machine frame. The machine frame is fixedly connected with a bearing base. The tail end,protruded out of the machine frame, of the cylindrical long rod passes through the bearing base for fixing. The sleeve is protruded out of the machine frame and extended to a position adjacent to thebearing base. The chain is sheathed in a position of the tail end, protruded out of the machine frame, of the sleeve, and the sleeve is driven to be rotated after the chain is rotated. The planter iscapable of effectively preventing the machine frame from generating the loosening, deforming and vibrating conditions in a working process, and greatly improving the stability of the device and the working efficiency in use.

Description

technical field [0001] The invention relates to an improved no-tillage and straw-covered precision seeder for stubble land. Background technique [0002] No-tillage and straw-covering precision seeder is widely used in agriculture. Take the typical 2BMFJ-6 no-tillage and straw-covering precision seeder as an example: 2BMFJ-6 no-tillage and straw-covering precision seeder is suitable for In my country's Huanghuaihai double-cropping area and most areas in Northeast China, no-tillage and straw-covering precision sowing and fertilization operations for soybeans, peanuts and other crops are directly carried out on the stubble land after machine harvesting. Such as figure 1 , figure 2 with image 3 As shown, the specific structure of the 2BMFJ-6 type no-tillage and straw-covering precision seeder includes a straw cleaning device, that is, a straw cleaning device assembly, which is arranged longitudinally on the bottom beam of the frame by six straw cleaning knife shaft assembli...

Problems solved by technology

In the actual operation and use process, the chain 203 runs to drive the fixed shaft 204 to rotate, thereby impelling the operation of the cutter 205. However, because the resistance of the cutter 205 is serious, frames such as the first frame 101 and the second frame 102. The lack of strong support causes the first frame 101 and the second frame 102 to be easily loosened, deformed and incited during use, which seriously affects the operation of the overall device and increases the maintenance cost of the device. Reduced operating efficiency of the device
