Embodiment Construction

[0021] The specific structure and working process of the present invention will be described below in conjunction with the accompanying drawings and examples.

[0022] A hole-type sowing and fertilizing driving device, comprising: a seeding and fertilizing shovel 1, a secondary shovel arm 2, a tension spring 3, a connecting plate 4, a slide rail fixing seat 5, a slide rail 6, a slider assembly 7, and a primary shovel arm 8. Drive groove 9, cam 10, camshaft 11.

[0023] The connecting plate 4 is a device fixing part, and is designed with bolt holes for connecting the driving device with the machine frame.

[0024] The cam 10 is installed on the camshaft 11, and the cam 10 makes a circular motion driven by the camshaft; the end of the slider assembly 7 is equipped with a bearing, and the bearing rolls in the cam groove, and then drives the slider assembly 7 along the slide rail. 6. Do reciprocating linear motion; the cam contour line is divided into 6 sections, respectively pus...

Abstract

The invention provides a hole sowing and fertilization driving device. The device comprises a sowing and fertilization shovel, a secondary shovel arm, a slide rail, a slider assembly, a primary shovelarm, a drive groove and a cam, wherein the cam drives the slider to conduct reciprocal rectilinear motion along the slide rail, and the upper end of the primary shovel arm moves in the drive groove relative to the drive groove; the middle of the primary shovel arm is hinged with the slider assembly and rotates relative to the slider assembly; the upper end of the secondary shovel arm is hinged with the primary shovel arm, and the lower end of the secondary shovel arm is connected with the sowing and fertilization shovel. The cam pushes a drive rod to realize lowering, translation and liftingactions under the joint constraint of the slide rail and the drive groove, and earth entering, shovel-seed separation and lifting earthing operation can be completed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a driving device for hole-type sowing and fertilizing for mechanized operations. Background technique: [0002] Most of the existing planting operations of hole-sowing crops are ditched by ditch openers to create good soil conditions for subsequent fertilization and sowing. After ditching, chemical fertilizers are applied in strips. The chemical fertilizers between two adjacent corn plants cannot be fully utilized by the crops, and the utilization rate of chemical fertilizers is low. . Hole-type sowing and fertilization is to open hole-shaped seed beds and fertilizer beds on the surface through the hole-opening device, and seeds and fertilizers fall into the seed holes or fertilizer holes through corresponding devices, which has the advantages of reducing soil disturbance during the operation process, water conservation and moisture conservation, and It is one of ...
