Problems solved by technology
Since the wheel diameter of the ground wheel is fixed, the adjustment of the sowing amount and fertilization amount of the seeder needs to be completed by a separate speed change mechanism. Not only the overall structure size of the machine tool is large, the weight of the machine tool is large, the structure is complicated, and the manufacturing cost is high. Moreover, the operation is difficult and the adjustment procedure is complicated

The invention relates to a diameter-adjustable land wheel of a seeding machine, belonging to agricultural machinery. A land wheel axle is rotatably provided with a wheel hub and an outer thread sleeve; twelve guide spoke rods are evenly and fixedly installed on the wheel hub; three outer ring diameter regulating sleeves, three inner ring diameter regulating sleeves and six support sliding block regulating sleeves sequentially and evenly sleeve the twelve guide spoke rods; three inner edgefold arc-shaped elastic outer wheel rings are respectively installed at the outer ends of the three outer ring diameter regulating sleeves; three sheet arc-shaped elastic inner wheel rings are respectively installed at the outer ends of the three inner ring diameter regulating sleeves; the six support sliding block regulating sleeves are respectively connected with corresponding support sliding blocks assembled on the inner wall surfaces of the sheet arc-shaped elastic inner wheel rings; twelve adjustment connecting rods are used for realizing the hinge joint between adjusting screw nut arranged on the outer thread sleeve and the regulating sleeves. The diameter-adjustable land wheel of the seedingmachine is novel, reasonable and compact in structure as well as simple, convenient and fast in diameter varying adjustment, can realize stepless regulation, and is high in applicability and reliableto use.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a ground wheel on a sowing machine tool for driving sowing and fertilizing components. Background technique [0002] At present, among the mechanical seed metering and planting machines produced and used in my country, the operating power of the sowing and fertilizer discharge parts comes from the ground wheel drive of the machine tool. Since the wheel diameter of the ground wheel is fixed, the adjustment of the sowing amount and fertilization amount of the seeder needs to be completed by a separate speed change mechanism. Not only the overall structure size of the machine tool is large, the weight of the machine tool is large, the structure is complicated, and the manufacturing cost is high. Moreover, the operation is difficult and the adjustment procedure is complicated. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in...
