Adjustable picking radius straw picker

Abstract

The application relates to a straw picker with adjustable picking radius, which includes a spring tooth assembly, and the spring tooth assembly includes a shaft frame, a rotating disk, a spring tooth seat, a spring tooth and a driving mechanism; the shaft frame includes a central shaft and a One end of the central shaft extends to the outside of one of the connecting parts to form an extension; the rotating disc is rotatably mounted on the extending part, and the rotating disc is provided with at least one arc-shaped guide rail groove; the spring tooth seat is at least It is set as one, one end of the spring tooth seat is hinged with the connecting part on the central shaft, and the other end of the spring tooth seat is provided with a protrusion that slides and fits with the arc guide rail groove; the spring tooth is installed on the other end of the spring tooth seat ; The drive mechanism includes a first transmission member and a second transmission member that are rotatably connected to each other, the second transmission member is fixedly connected to the extension, and the first transmission member is installed on the turntable. Through the above arrangement, the adaptable range of the picker is improved, and the cleaning rate and efficiency of picking up can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a straw picker with adjustable picking radius. Background technique [0002] The straw spring tooth picker is a common part used in straw collection in the agricultural field. It is used in straw balers, straw pickers and other agricultural machinery. According to the classification of pickers, it can be divided into cam pickers and camless pickers. Type pick-up, and the emerging pick-up without retainer. The purpose is to improve the cleaning rate and efficiency of straw picking. [0003] The main grain crop in the Northeast Great Plains is corn, and the ridge planting system is implemented. After the crops are harvested, the straw is coarsely crushed to the field. When the straw is in the furrow, the conventional spring-tooth picker can pick up the straw on the ridge surface, which is limited by the picker’s bullet. The consistency of the length of the teeth ca...

Problems solved by technology

[0003] The main grain crop in the Northeast Great Plains is corn, and the ridge planting system is implemented. After the crops are harvested, the straw is coarsely crushed to the field. When the straw is in the furrow, the conventional spring-tooth picker can pick up the straw on the ridge surface, which is limited by the picker’s bullet. The consistency of the tooth length The straw in the furrow cannot be picked up

[0004] The spring tooth assembly of the existing picker realizes the picking up of the ridge surface and the straw in the furrow through the high and low spring teeth. When type, there is a problem of poor adaptability
