Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 7As shown, a variable-variable ditch burying and returning device for crushed straw of the present invention includes a rolling shutter driving mechanism, a coupling 2, a rolling shutter mechanism, a screw conveying mechanism 7, a screw conveying housing 8, a grass bearing plate 21, and a straw guiding housing 14, beam frame 9 and double-sided furrowing plow 15. The device is assembled on the horizontal straw crushing and field returning machine through the traction frame 1 .

[0029] The beam frame 9 is horizontally arranged on the lower side of the device, such as Figure 5 As shown, the beam frame 9 includes a pair of cros...

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a smashed straw quantitative ditch-buried and returning-to-field device. A two-sided ditching plow of the device opens a straw burying ditch, a roller blind driving mechanism drives a roller blind (12) to be opened and fixes the positions of a spiral nut (10) and a connecting plate (11), the opened roller blind (12) blocks smashed straw (22) sent by a smashing mechanism in the front, the smashed straw (22) falls into a spiral conveying mechanism (7), a left spiral blade (702) and a right spiral blade (703) on a rotating shaft (701) convey the smashed straw from the two ends to the middle, and through a central hole of a spiral conveying casing (8), the smashed straw (22) blocked by the roller blind (12) is guided into the straw burying ditch through a straw guiding casing (14). The smashed straw returns to fields partially by burial and partially by earth surface covering, the quantitative adjustment of the proportion of the smashed straw returning to field by ditch burial is achieved, and the adaptability is good under the conditions of a large straw amount.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a crushed straw variable ditch burying returning device used in conjunction with a horizontal straw crushing and returning machine. Background technique [0002] In modern agricultural production, the crushed crop stalks are often evenly covered on the ground surface, which can change the physical and chemical properties of the soil, fertilize the soil, etc. However, with the increase of crop yield, the amount of straw increases, and the method of crushing and covering the ground in full amount brings great difficulties to the subsequent plowing and sowing operations. Therefore, it is imperative to actively explore and find new ways of straw returning. Among them, straw crushing and ditch burying have gradually become a research hotspot. Patent CN200910223897.3 discloses a crushed straw deep application machine, which uses a hydraulic device to drive t...
