Embodiment Construction

[0015] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0016] Such as figure 1 , figure 2 , image 3 As shown, a schematic diagram of the specific embodiment of the profiling seed guide of the present invention is provided, including a ditching disc 2, a profiling wheel 3, a seed introduction tube 5, and a single beam 9. The profiling wheel 3 is arranged on the The outer side of the ditching disc 2 also includes a support arm 1, a soil retaining wall 4, a soil retaining shovel 6, and a pre-tensioned tension spring 10. A pre-tightened extension spring 10 is arranged obliquely, the rear end of the pre-tightened extension spring 10 is hooked to the middle position of the support arm 1, the front end of the pre-tightened extension spring 10 is attached to the front end of the single beam 9, and the rear end of the support arm 1 supports A support shaft is arranged on the seat, and a ditching disc 2 ...

Abstract

The invention discloses a profiled seed guider, aiming at providing a profiled seed guider which is good in seeding operation quality and high in adaptability. A pre-tightening tension spring is arranged under the front of a support arm in an inclined way; a trenching disc is arranged on a support seat at the rear end of the support arm; the horizontal projection of the trenching disc inclines towards the outer side from front to back along a longitudinal advancing line; the support seat at the rear end of the support arm is sequentially provided with a soil retaining spade and a soil retaining wall from front to back; a front cutting edge of the soil retaining spade inclines backwards from top to bottom, and presses and clings to the inner side face of the trenching disc inwards; the rearedge of the soil retaining spade is connected with the front edge of the soil retaining wall; a seed guide pipe is arranged at the upper edge of the soil retaining wall; the seed guide pipe is vertically arranged in a groove area downwards, and the groove area is defined by the inner side face of the trenching disc and the inner side face of the soil retaining wall. The profiled seed guider is suitable for being matched with a ridge double-row or single-row seeder for use.

Description

technical field [0001] The invention relates to a seed guide for a planter, in particular to a profiling seed guide. Background technique [0002] The seed guide of the existing pneumatic seeder is generally mainly composed of a ditching disc, a profiling wheel, and a seed guide tube. On the top, the seed guide tube is fixed on the sowing monomer frame. In the operation process, the seed guide and the suppressor formed by the ditching disc, the profiling wheel and the seed guide pipe follow the overall profiling of the sowing single frame, because the seed guide cannot follow the ground profiling alone. In the high-speed operation state, the overall profiling sensitivity of the sowing single frame will decrease, and the profiling error along the ground surface will be large, which will directly affect the consistency of sowing depth and the quality of sowing operations. In addition, the supporting arm of the profiling wheel is fixedly mounted on the rear end of the sowing ...
