Sowing implement

Abstract

The invention discloses a seeder which precisely controls the amount of various chemical fertilizers and simultaneously regulates the precise sowing of seeds very conveniently. It includes a seed bin, a fertilizer bin and a seeding hub. There are chutes on the two side walls of the seed bin, and the two sides of the slide plate are embedded in the chute and slide with the chute; The slotted plate is embedded in the chute and slides with the chute. There is a fertilization impeller in the fertilizer bin. The fertilization shaft on the outer side of the housing is equipped with a slave gear. The slave gear meshes with the main gear. The bottom of the fertilizer bin is a through hole. , There are chute on both side walls of the through hole, the two sides of the adjustment plate are embedded in the chute, and slidingly fit with the chute; the center of the sowing hub is equipped with a sowing shaft, and the spring is located in the sowing hub and sleeved on the sowing shaft; The sowing hub is composed of an outer hub and an inner hub, and the outer hub and the inner hub are axially slidable; the main gear is installed on the sowing shaft on the outer side of the housing, and a mounting hole is provided on the other side of the housing, and the sowing shaft at the mounting hole is installed With adjustment bolt.

Description

technical field [0001] The present invention relates to an agricultural implement, especially a sower. Background technique [0002] Now, various seeders emerge in an endless stream. However, the structure basically adopts the fertilizing mechanism and the seeding mechanism with fixed functions. In the process of agricultural mechanization development, agricultural machinery has gradually entered the farm, especially the family-based agricultural mechanization operation, which requires the miniaturization and multi-functionalization of agricultural machinery to reduce investment and realize the multi-purpose of one machine. The patent No. is the Chinese patent of 200420055410.8. The main technical scheme adopted is: the bottom seed outlet of the seed and the chemical fertilizer box, and the corresponding fertilizer outlet are the sowing wheel and the fertilizing impeller, and the sprocket wheel at one end of the fertilizing impeller shaft is connected with the sowing wheel,...

AI Technical Summary

Problems solved by technology

Therefore, the sowing wheel and the fertilizing impeller can only perform the functions of sowing and fertilizing respectively, and it is difficult to accurately control the amount of fertilization, it is difficult to realize precise fertilization control for different types of chemical fertilizers, and it is also inconvenient to adjust the precise sowing of seeds
