Seed furrow liquid spraying type seed anti-bouncing device

Abstract

The invention relates to a seed furrow liquid spraying type seed anti-bouncing device which comprises a frame, a handle welded part and two cutter discs, wherein the handle welded part comprises a handle, two stepped shafts and a seed guide pipe; the stepped shafts are symmetrically fixed under the two sides of the handle; the seed guide pipe is fixedly arranged on the surface of the handle along an advancing direction of the device in a bias form; the two cutter discs are respectively arranged on the two stepped shafts; the device is characterized in that a water pump is welded between the frame and the handle welded part; a water tank or a drug box is connected with a liquid inlet of the water pump; a flow guide pipe is connected with a liquid outlet of the water pump; a water outlet of the flow guide pipe is toward the advancing direction of the device; a PLC controller and a direct current power supply are arranged on the frame; a power supply input end of the PLC controller is connected with a power supply output end of the direct current power supply; the water pump is connected with the PLC controller; an inclined angle of the projections of the axis of the stepped shafts and the asymmetry axis of the handle welded part along the advancing direction is alpha; alpha is more than or equal to 2 phi / 5 but less than or equal to phi / 2; the inclined angle of the projections of the axis of the stepped shafts and the asymmetry axis of the handle welded part in a horizontal plane is beta; beta is more than or equal to 2 phi / 5 but less than or equal to phi / 2. The device can effectively control the seed falling position and can promote the seed feeding precision.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a seed ditch liquid spraying type anti-bounce device. Background technique [0002] Seeding plays a vital role in agricultural production. With the rapid development of planting machinery worldwide, the quality of sowing operations has also been significantly improved, mainly reflected in the continuous improvement and optimization of seed meters. However, in the actual field sowing operation, the sowing quality is often difficult to meet the expected requirements, such as the qualified index of grain distance and the lateral variation coefficient of grain distance. The main reason is that in the actual sowing process, the moment the seeds leave the seed meter and fall into the seed ditch, they will collide with the soil of the seed ditch, resulting in a certain degree of bouncing and rolling. This process will make the seed particle distance qualified. The decrease of the ind...
