Dual-chamber dibbler

Abstract

The invention belongs to the technical field of design and manufacture of agricultural machinery, in particular to a dual-chamber dibbler. The dual-chamber dibbler comprises a dibbler main shaft, wherein the dibbler main shaft is connected with a fixed disk and a moving disk; at least two seed inlet pipes are arranged on the fixed disk; the fixed disk is connected with a center sealing disk; a transition pipe and a seed limiting pipe are separately connected to the center sealing disk; a seed taking disk, an isolation disk, a hole separating disk and a pressing disk are arranged behind the center sealing disk; the hole separating disk is connected with the periphery wall in a seed ring through a flange piece; and besides, the inner part of the whole dibbler is separated into two independent seed chambers in front and rear; the seed ring is fixed between the two independent seed chambers by the moving disk and the pressing disk; two rows of through holes are formed in the periphery wallof the seed ring, and separately correspond with a main seed chamber and a secondary seed chamber; and a duckbill assemble is arranged on the seed ring. According to the dual chamber dibbler disclosed by the invention, a conventional single seed cavity type dibbler is newly designed; and when the dual-chamber dibbler is adapted to different seeds or the same seeds or pills or slow-release nutrition capsules, the technical problems of missed sowing and following sowing are well solved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of agricultural machinery, and in particular relates to a double-chamber hole seeder. Background technique [0002] At present, with the continuous development of film-laying sowing technology in China, in some areas, it is necessary to simultaneously sow the main crop seeds and auxiliary seeds, such as wheat seeds; or pills, such as slow-release nutritional capsules, etc. Together. However, in actual production, for example, in Xinjiang, cotton is the most important economic crop. When cotton is planted with film, it is often necessary to use cotton seeds as the main crop seeds for precision sowing. In order to ensure the production effect of the precision sowing of cotton seeds, It is generally not recommended to sow cotton seeds mixed with auxiliary crops or pellets. At the same time, according to the requirements of production practice, it is best to sow auxiliary crops or slo...

AI Technical Summary

Problems solved by technology

However, after an in-depth study of cotton planting in several countries around West Asia, it was found that although these countries have adopted the precision hole seeder commonly used in Xinjiang, my country, although the sowing effect can be improved, the sowing efficiency is not high, and often occurs Production technical problems such as missed broadcast and wrong broadcast

One of the main reasons is that these countries do not carry out standardized treatment of cotton seeds in the early stage due to environmental protection requirements or other factors (cotton seeds in my country are all processed by chemical melting, cotton seeds will not contain lint and basically can maintain a uniform size), so that the cotton seeds in these countries basically have more or less lint, while the precision hole seeders in my country basically only have one feeding port, and there is no redundant choice. During the sowing and use of these countries, the cotton seeds with lint will block the outlet of the precision hole planter after a long time, resulting in missed sowing or even directly "suffocate" the hole planter, forming idling. At this time, it must be stopped immediately to carry out the hole planter The desilting and blockage removal has resulted in the efficiency of its continuous operation and the effect of sowing can not be improved to the level of Xinjiang
