Embodiment Construction
[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0020] Such as Figures 1 to 6 As shown, the corn full-film double-groove nearly constant-velocity in-line compensation device includes a frame 17 on which a motor 2 and an operating handle 20 are arranged, and the feature is that the front part of the frame 17 is also A rotating guide rod mechanism 7 is provided, and the rotating guide rod mechanism 7 is respectively connected with the motor 2 and the sinusoidal mechanism 6 through a power transmission mechanism. An in-line sowing mechanism 18 connected with the motor 2 is arranged under the frame 17, corresponding to the in-line sowing mechanism. The frame 17 above the mechanism 18 is provided with a seeding mechanism 22 .
[0021] Further, the tail wheel 21, the...

The invention relates to the technical field of sowing equipment among agricultural machines, in particular to an approaching-constant-speed direct plug-in compensation device for all-film double-furrow sowing for corn. The compensation device comprises a rack, wherein a motor and operation handles are arranged on the rack. The compensation device is characterized in that a rotating guide rod mechanism is arranged in the front of the rack, and connected with the motor and a sine mechanism through a power transmission mechanism; an indirect plug-in sowing mechanism connected with the motor is arranged at the lower part of the rack; a seed feeding mechanism is arranged at the position, corresponding to the upper part of the direct plug-in sowing mechanism, of the rack. The compensation device has the advantages that the rotating guide rod mechanism and the sine mechanism cooperate in a serially connected manner to control and harmonize the direct plug-in sowing mechanism with other parts, so that the horizontal component velocity of a soil opener on the sowing and unearthed sections is zero, and the arrangement of soil holes and the motion trail of sowing operation are reasonable; through adoption of the forced sowing mechanism, the soil opener can be accurately opened for seed discharging and rapidly closed after pricked in a film-covered seedbed, so that the problems of too many seeds or no seed in one soil hole during under-film sowing and blockage in the soil opener can be effectively solved.
Description
technical field [0001] The invention relates to the technical field of sowing equipment in agricultural machinery, in particular to a near-constant-velocity in-line compensation device for corn full-film double-furrows. Background technique [0002] The full-film double-furrow sowing technology is a breakthrough innovation in the development of dry farming in Northwest my country in recent years. It is mainly proposed for corn production and planting. It is required to lay the film on the ridge first, and then complete the sowing on the film in the small ridge and furrow. Its main features are: in late autumn and early spring, double wide and narrow ridges are formed first, and at the same time, the entire ground surface is covered with plastic film, and on-demand sowing in the ridges is done in due time during the sowing period, which can effectively store precipitation, increase ground temperature, and reduce field damage. Evaporation can effectively improve the growth env...
