New rolling harrow

Abstract

A novel rolling harrow belongs to the technical field of agricultural implements. Its purpose is to provide a machine that can not only crush the soil clods, roll the harrow without jumping, but also level the land at the same time during the harrowing process; the vibration of walking on the mechanical plowing road is small, and it will not cause damage to the top of the support block. New rolling harrow. Its technical points are: rolling (2) the tops of the adjacent two rings of sheet rake teeth (3) in the middle of the cylindrical surface are welded with channel irons (4) respectively, and a hoop (4) is welded between the adjacent two rings of channel irons ( 5); the rear of the rectangular rake frame is provided with a drag plate (6). The channel iron is welded on the top of the adjacent two rings of sheet rake teeth, which enhances the crushing function and flexibility of the soil. A hoop is welded between two adjacent channel irons to make the rolling rake stable during the plowing process. Walking on the mechanical tillage road not only protects the channel iron from damage, but also reduces vibration; a drag plate is set behind the rake frame , to prevent the soil from splashing when plowing the land, and to level the rolled ground at the same time.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a novel rolling harrow. Background technique [0002] Chinese patent 200620075737.0 discloses a seat tillage rolling harrow, which is composed of a rectangular harrow frame and two cylindrical rolls installed side by side under the rectangular harrow frame. , support blocks are evenly distributed on the same radial direction in the middle of the rolling cylinder, and the rolling harrow increases the rolling resistance by adding support blocks on the rolling, though it reduces the resistance of the rolling advance and enhances the anti-slip function of the rolling. However, due to the large distance between the adjacent support blocks arranged in the radial direction of the rolling cylinder, the beating of the rolling is relatively severe during the harrowing process. Damage to the top of the strut. Simultaneously, the flatness of the ground that has been raked through the rolling an...

Problems solved by technology

However, due to the large distance between the adjacent support blocks arranged in the radial direction of the rolling cylinder, the beating of the rolling is relatively severe during the harrowing process. Damage to the top of the strut

At the same time, the flatness of the ground that has been raked by the rolling rake is also poor.
