Straw tedder

Abstract

The invention discloses a straw tedder. A forward shaft is arranged at the front end of an underframe, a drive shaft is arranged in the middle of the underframe, a back shaft is arranged at the back end of the underframe, front crawler wheels are arranged on the left side and the right side of the forward shaft, caterpillar drive wheels are arranged on the left side and the right side of the drive shaft, back crawler wheels are arranged on the left side and the right side of the back shaft, and caterpillar bands are respectively installed on the crawler wheels on the left sides and the right sides. A walking drive motor is arranged on the back left side of the underframe, a worm gear case is arranged at the front end of the walking drive motor, an operating arm is arranged on the middle back portion of the underframe, an upper support is arranged at the upper end of the operating arm, a left rod turning follow-up sheave is arranged at the upper end of the upper support, a lower support is arranged at the lower end of the operating rod, a right rod pulling follow-up sheave is installed at the lower end of the lower support, a take-up rod is arranged at the front end of the underframe, and an operating handle is arranged at the back end of the operating arm. When the straw tedder operates, the operating handle is held by two hands of an operator, a walking control switch is rotated by the right hand, and overturning of the straw tedder is achieved under cooperation of a left tooth profile strap turning rod, a supporting rod and a pressing rod.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a crop stalk tumbler. Background technique [0002] my country is a large agricultural country, and a large amount of straw is produced every summer and autumn, and the straw can be returned to the field as organic fertilizer, recycled for papermaking or used as raw material for the feed industry. As a large number of farmers migrate to cities to work, most of the rural labor force is the elderly, women and children. During the critical period of harvesting and planting, a large amount of straw cannot be recycled because it cannot be turned in time. Although the country invests a lot of manpower, material and financial resources every year to ban straw burning, a large amount of straw is still burned, which wastes resources and pollutes the environment. To solve this problem, the straw must be returned to the field or recycled and reused. The technology of straw returning to the field ...

As a large number of farmers migrate to cities to work, most of the rural labor force is the elderly, women and children. During the critical period of harvesting and planting, a large amount of straw cannot be recycled because it cannot be turned in time

Although the country invests a lot of manpower, material resources, and financial resources every year to ban straw burning, a large amount of straw is still burned, which wastes resources and pollutes the environment.

To solve this problem, the straw must be returned to the field or recycled and reused. The technology of straw returning to the field has not yet been popularized in my country, and the premise of recycling and reuse is that the straw must be dried quickly. The current traditional tumbling method, It is laborious and time-consuming, so many farmers do not consider the recycling of straw at all, and sometimes even burn it with a fire before it can be turned over.
