Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for purposes of illustration and explanation only and are not intended to limit the invention.
The utility model discloses a harrowing device, as shown in fig. 1-2, including mounting bracket 100, harrow tooth row and rolling mechanism, wherein, be constructed with mount pad 102 on the mounting bracket 100, this mount pad 102 is used for being connected with agricultural machinery and flexible connectors 300 respectively. The rake teeth row is composed of a plurality of rake teeth 200, the rake teeth 200 are arranged in a circular arc shape, and the middle part of the rake teeth row protrudes towards the direction far away from the agricultural machinery. The mounting seat 102 of the mounting rack 100 is detachably connected with the rolling mechanism through an elastic connector 300, and the rolling mechanism is located behind the rake teeth. The utility model discloses a theory of operation and advantage lie in: the utility model has the advantages that the rake teeth are in the arc-shaped structure, and the middle part of the rake teeth protrudes towards the direction far away from the agricultural machine, so that in the process that the rake teeth are dragged by the agricultural machine to rake off straws, sundries and the like on the surface of a farmland, the sundries such as straws and the like raked at the two sides of the rake teeth can be gathered towards the middle of the rake teeth, and further the sundries such as straws and the like on the two sides are prevented from leaking; meanwhile, the rolling mechanism is arranged behind the rake teeth row, namely after the surface of the farmland is scratched by the rake teeth row, the turned-up part of the farmland is rolled by the rolling mechanism so as to be flattened, and the hardness of the surface of the farmland is slightly improved due to the action of the rolling mechanism, so that the scattering rate of moisture contained in the soil is greatly reduced compared with that of the prior art; therefore, the utility model discloses avoided the straw to break away from by the both sides of rake teeth row, and improved soil moisture's holding capacity simultaneously.
