Description
Technical Field
The utility model relates to the technical field of agricultural machinery, concretely relates to improvement structure of disc furrow opener.
Background
Commonly used agricultural furrow openers are of the disc type, hoe-shovel type, sliding cutter type and the like. The disk furrow opener does not stir the soil layer during operation, can directly bury seeds and fertilizer into the turned soil layer, and has very wide application. However, the disc furrow opener with the existing structure has short service life due to the fact that the working environment is very dusty, and the bearing position enters and is filled with dust after the disc furrow opener is used for a period of time, so that the disc furrow opener slowly loses the rotating capability, and normal production operation is influenced.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: aiming at the problems, the furrow opener with good sealing effect and long service life is provided.
The technical solution of the utility model is that: a disc furrow opener comprises a disc, a rotary disc shaft and a bearing, wherein the disc is assembled on the rotary disc shaft through the bearing, the disc furrow opener also comprises a bearing seat sleeve and a sealing cover, the central position of the inner side end of the bearing seat sleeve is provided with a shaft hole, the outer edge of the inner side end of the bearing seat sleeve is provided with a flange connecting part, the outer side end of the bearing seat sleeve is provided with a bearing chamber for placing the bearing, the end part of the rotary table shaft is provided with a circular bead, the disc is sleeved on the rotary table shaft at the circular bead and is in clearance fit with the rotary table shaft, the bearing seat is sleeved on the outer side end of the disc and is sleeved on the rotary table shaft and is in clearance fit with the rotary table shaft, the bearing is arranged in the bearing chamber of the bearing seat sleeve and is sleeved on the rotary table shaft, the disc and the sealing cover are provided with through holes corresponding to bolt holes of the flange connecting part of the bearing seat sleeve, and the sealing cover seals the bearing in the bearing chamber outside the bearing seat sleeve and is fixedly connected with the disc and the bearing seat sleeve through bolts.
The technical effects of the utility model are that: the novel dust-proof sealing device has the advantages of simple structure, reasonable design, good sealing effect and long service life, and can effectively prevent dust from entering and achieve the purpose of prolonging the service life.
