Method for manufacturing grass proof rotary tillage machine
- Sep 05, 2017 -

All rotary tillage machinery in the operation process, the main problem is in the cutter shaft assembly with a bearing seat, such as winding side cutter shaft, cutter shaft between the left bearing cover bearing right weeds and straw and support each other, when the knife shaft assembly speed, weed straw mixture immediately drilling cutter shaft shaft and the bearing plate combined with the gap, the knife shaft assembly and spindle bearing plate cling, increase resistance to rotation of cutter shaft assembly, thus increasing power consumption of tractor reached more than 10%. At the same time, it is easy to damage the side plate, bearing block and other support parts. For example, each tractor consumes 2 tons of diesel oil annually as an example, at least 200 kilograms of diesel oil is used for the shaft winding problem, and 1 million tons of diesel oil is consumed more than 200 thousand tons per year in order to calculate the number of tractors in our country. At present, some manufacturers have made improvements, that is, in the shaft assembly at the head of a metal ring set, trying to stop the weeds and straw directly from the shaft assembly shaft head and support parts into the drill. But the weeds and straw were drilled in the gap between the iron sheet ring and the side plate bearing seat, and the improvement was not high. The technical problem to be solved by the utility model is to counter the shortage of the prior art, and to prevent the resistance of the cutter shaft and reduce the power consumption. Technical problems to be solved by the utility model is realized through the following technical scheme, a grass winding prevention type rotary machinery, including about two knife shaft assembly, intermediate gear box and two side box plate, cutter shaft assembly includes a plurality of blade on a rotating shaft rotating shaft and installed, and its characteristics are the two ends of the rotary shaft are provided with bowl shaped floating grass winding prevention ring groove matched with the bowl sized grass winding prevention ring are arranged on the fixed part of the middle of the inner side of the transmission box on both sides and both sides of the box plate. Technical problems to be solved by the utility model can also through the following technical scheme to realize further, fixing member comprises a side bearing seat is arranged on both sides of the box plate, and arranged in the middle of the intermediate gear box bearing and intermediate bearing end cover. The fixed part can also be on both sides of box board, intermediate transmission box, directly open on both sides of the groove box board, intermediate gear box, but this bowl circle on the grass winding prevention to do great, not economic. Technical problems to be solved by the utility model can also through the following technical scheme to further realize the grass winding prevention ring bowl, diameter and wall thickness of I. 90mm LIOmm, 5mm 6mm. Compared with the prior art, the bowl shaped grass winding prevention floating ring installed at both ends of the rotating shaft, showing a non rotating like state, blocking each other at gap junction rotating parts and fixed parts, i.e. the gap between the rotating shaft and bearing. In addition because the bowl shaped grass winding prevention ring is arranged in the opening groove, forming a labyrinth seal. So, when the rotary shaft rotates at a high speed, it is driven by the flexible material splash mud and straw, weeds may not be between the winding and combination of the rotary shaft and the bearing, to completely solve the problem of straw winding weeds, reduce the movement resistance of the cutter shaft, reduces the power consumption.


A grass winding prevention type rotary machinery, including about two knife shaft assembly, intermediate transmission box 7 and box 11 on both sides of plate, knife shaft assembly comprises a rotating shaft and a plurality of blade on the rotating shaft on the I 12, at both ends of the rotating shaft I floating bowl with grass winding prevention ring 4 block a bowl shaped groove and the grass winding prevention ring 4 with opening are arranged on the fixed part of the transmission box 7 on both sides of the middle and the two sides on the inner side of the box plate 11. A formation of labyrinth seal in block groove. The fixing component comprises a side bearing seat 10 arranged on the two sides of the box board, an intermediate bearing seat 6 and an intermediate bearing seat end cover 5, wherein, the middle bearing seat 7 is arranged on the middle drive box body. The fixed part can also be on both sides of box board, intermediate transmission box, directly open on both sides of the groove box board, intermediate gear box, but this bowl circle on the grass winding prevention to do great, not economic. I is provided with a rotating shaft intermediate shaft tube, welded on the outer end of the axle shaft tube is welded with a spline sleeve 2, 3 end of the shaft tube, bearing and shaft installed on both sides of the box plate, a spline sleeve 3 is installed in the middle drive spline in the bearing seat with 9, 8 knife shaft gear drive spline 9 rotation. The bowl shaped grass winding prevention suit in a floating ring shaft 2 and spline sleeve 3, by the end of the axial positioning shaft tube. The bowl shaped grass winding prevention ring outside diameter 90mnTll0mm, wall thickness of I.
