Problems solved by technology

[0003] When the traditional drill technology is used for sowing wheat with a large width, it is necessary to configure multiple openers to cover the entire width. When multiple openers are closely arranged, congestion is likely to occur, and the staggered arrangement will cause the machine tools to be too long, which is not conducive to the machine tools. Hanging and Transport
When the traditional sowing technology is used for super large width sowing of wheat, the width can be adjusted to meet the uniform sowing in the seedling belt, but the sowing depth cannot be controlled, and it is easy to damage the seeds during the mechanical mixing process of the soil.

Abstract

The invention provides an equal-depth broadcasting device for crop seeds. A drive shaft is arranged below a rack, and multiple soil throwing devices are arranged on the drive shaft; multiple soil guide plates are obliquely arranged behind the rack, the back side of each soil guide plate inclines towards the back lower side of the rack and located on the back side of the corresponding soil throwingdevice, a soil guide plate adjusting device is rotationally mounted behind the rack, the front end of the soil guide plate adjusting device is rotationally connected with the rack, and the other endis connected with the soil guide plate; a seed box is arranged above the rack, seed metering devices with the number and positioning corresponding to those of the soil throwing devices are arranged atthe bottom of the seed box, a seed spray pipe vertically penetrating through the corresponding soil guide plate is arranged below each seed metering device, an arched horn shaped seed spray port witha backward opening is formed in the bottom of each seed spraying pipe and located between each soil throwing device and the soil guide plate, a fan is arranged on one side of the seed box, and an airoutlet of the fan is connected with each seed spray pipe through multiple air guide pipes. The equal-depth broadcasting device for crop seeds sprays seeds by using airflow, can realize equal-depth broadcasting with super large width, is compact in structure and does not damage the seeds.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an iso-deep spreading device for crop seeds. Background technique [0002] Wheat wide-width sowing is to change the traditional narrow-width drill sowing with dense seeds into wide-width grain sowing that the seeds are evenly distributed within a certain width range, which can reduce the competition for water and nutrients among individuals, and is conducive to ventilation, Translucency is already recognized in the industry as a means of increasing production. A no-tillage planter for collecting and covering straw between rows (CN201810861380.6) can complete the operations of crushing straw, clearing the seed belt, covering straw between rows, fertilizing and seeding, and covering soil for suppression in one go to the field, and can form a 25-30cm super Large and wide seedling belt, especially suitable for wide sowing of winter wheat after rice harvest in rice-wheat rotation area. Howe...
