Fertilizing and seeding device for precision seeder

Abstract

The invention discloses a fertilizing and seeding device for a precision seeder. The fertilizing and seeding device comprises a main body machine frame, a suspension connecting mechanism, fertilizingmechanisms and seeding and soil returning mechanisms, wherein the suspension connecting mechanism is mounted on the main body machine frame, and the fertilizing mechanisms and the seeding and soil returning mechanisms are connected through the suspension connecting mechanism; and the suspension connecting mechanism comprises a connecting beam fixedly connected with the at least one group of seeding and soil returning mechanisms, a cross beam fixedly connected with the at least one group of fertilizing mechanisms and at least one connecting frame used for connecting the connecting beam and thecross beam, and each group of fertilizing mechanisms and the corresponding seeding and soil returning mechanism are arranged in a staggered mode; each group of seeding and soil returning mechanism comprises a seeding assembly and a soil returning and pressing assembly which are correspondingly arranged on a frame body front and back, and the frame body is fixed to the connecting beam. The gap between the fertilizing mechanisms and the gap between the corresponding seeding and soil returning mechanisms are convenient to install and adjust, the actual use requirements are met, and accurate seeding and soil returning gaps are achieved. The fertilizing and seeding device is suitable for field crop seeding, and is used for fertilization, seeding, soil returning and pressing.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a fertilization and seeding device for a precision seeder. Background technique [0002] At present, when the seeder is used for operation, the main frame of the seeder in the prior art is provided with a connecting beam, the front part of the connecting beam hangs the fertilization mechanism, and the rear part of the connecting beam is connected with the seeding mechanism through parallel four links, and the connecting beam is also connected to the seeding mechanism. Separately fix back soil suppression mechanism. When working, the fertilizing mechanism first fertilizes, then the seeding mechanism sows, and finally the soil return suppression mechanism performs soil return suppression to ensure that the seeds can germinate and grow normally. There are following deficiencies in actual use: [0003] One is that the installation positions of the seeding mechanism a...

Problems solved by technology

Since the ditch opener and the return soil suppression wheel in the prior art are separately fixed on the connecting beam, this part of the radial force can only be offset by the ditch opener or the return soil suppression wheel itself, which makes ditching very easy. The vibrating phenomenon of the device or the return soil suppression wheel is likely to cause equipment damage, and to a certain extent also affect the accuracy of sowing
