Abstract

The invention discloses a board-tooth harrow for grain sunning. The board-tooth harrow comprises a handle (1), an outer harrow handle (2), an inner harrow handle (3), an adjusting device and a connecting rod (4), wherein the outer harrow handle (2) is arranged on the end face of the handle (1) and is in rotary linkage with the handle (1); the inner harrow handle (3) is arranged at the inner side plane of the outer harrow handle (2) and is in sliding linkage with the outer harrow handle (2); the adjusting device is in threaded connection with the handle (1); and the connecting rod (4) is linked between the inner harrow handle (3) and the adjusting device, and thus the requirements on spreading and turning over the grains are met.

Description

[0001] 1. Technical field [0002] The invention relates to a flat-toothed harrow, in particular to a flat-toothed harrow used for drying grain. 2. Background technology [0003] When drying food crops, it is necessary to use agricultural tools for thinning and turning. Generally, plate rakes and toothed harrows are used. Therefore, plate-toothed harrows are an important agricultural tool. It is separated from the tooth rake, and the two are not combined, so it cannot meet the requirements for drying food crops. 3. Contents of the invention [0004] In order to overcome the above-mentioned technical shortcomings, the object of the present invention is to provide a flat-tooth harrow for grain drying, thus meeting the requirements of thinning and turning of grain. [0005] In order to achieve the above-mentioned technical purpose, the technical solution of the present invention is: comprising a handle, an outer rake plate arranged on the end face of the handle and arranged ...
