Abstract

The invention relates to a transmission device for an inter-row seeding machine, which belongs to the technical field of agricultural machinery. In the invention, upper ends of land wheel supporting arms are hinged with a land wheel connecting seat, and lower ends of the land wheel supporting arms are movably connected with stubble avoiding land wheels through a land wheel shaft; one end of the land wheel shaft is fixedly connected with an overrunning clutch sprocket wheel and the inner ring of an overrunning clutch, and the clutch sprocket wheel is in chain connection with a intermediate drive sprocket wheel through a chain and a double-tensioning sprocket wheel; the intermediate drive sprocket wheel is fixedly connected with one end of a intermediate transmission shaft, and the other end of the intermediate transmission shaft is movably connected with a seed box support through a bearing; and one end of a double-tensioning seat plate is fixedly connected with the land wheel supporting arms, and the other end of the double-tensioning seat plate is fixedly connected with a tensioning cushion cover. The transmission device is compact in structure, and the land wheels therein can walk on the stubble field reliably; and the transmission device can solve the problems of influence on the operation performance of a machine tool and damage to the machine tool caused by the situation that other components of the machine tool generate reverse rotating due to the contrarotating of land wheels during the transportation or operation of the machine tool, and can be widely applicable to various types of inter-row seeding machines and similar agricultural machinery.

Description

technical field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a transmission device for an inter-row seeder. Background technique

[0002] The transmission system is an important part of the seeder, and the reliable transmission device provides a guarantee for the quality of sowing. At present, the sowing mechanical transmission device mainly has the following two structures:

[0003] One is to use the ground wheel as the power source, and adopt multi-stage chain transmission to realize the transmission process. The ground wheel is in the form of an inflatable rubber wheel or an iron wheel. Shuangfu brand two-row corn precision seeder is a widely used model in Jilin Province. The power is transmitted from the ground wheel to the intermediate shaft, and then respectively for fertilization and seeding transmission. There is no tensioning and clutch device. It is extremely inconvenient to adjust the height of the gr...
