Furrow opener of wheat sowing machine and furrow opener assembly

Abstract

The invention provides a furrow opener of a wheat sowing machine and a furrow opener assembly. The furrow opener is composed of a fixed frame (13), a shaft (1), a furrow opening sheet (2), a fixed frame upper eave (5), a seed conveying pipe (6), a fertilizer discharging pipe (7), an outer mud scraping plate (3), a front soil baffle plate connecting seat (14), a front soil baffle plate (4) and thelike. The furrow opener of the wheat sowing machine further comprises the furrow opening sheet (2), the fixed frame upper eave (5), the seed conveying pipe (6), the fertilizer discharging pipe (7), aspring plate (8), a spring secondary plate (9), a square pipe (11), a U-shaped clamp (12) and a bearing seat (16); a main beam fixed seat (10) is clamped onto the upper end of the spring plate (8) andthe spring secondary plate (9), tightly holds the square pipe (11), and is connected and fixed by the U-shaped clamp (12) which penetrates through a fixed seat connecting hole (10-1). The furrow opener of the wheat sowing machine and the furrow opener assembly, provided by the invention, have the characteristics of novel structure, low manufacturing cost, good working quality, high working efficiency, few working faults and wide applicable range.

Description

technical field

[0001] The invention relates to an agricultural machine, mainly to a trench opener and an opener assembly of a wheat seeder. Background technique

[0002] At present, the conventional 24-row or 48-row wheat planters are known to be horizontally hoisted and equipped with 24 or 48 sets of double-disc openers on the same beam of the frame assembly in order to telescopically erect the openers. The profiling mechanism composed of rods and pressure springs realizes the single profiling control of each group of double-disc openers. Due to the too small spacing between adjacent double-disc openers, the operation is seriously blocked and requires harsh ground preparation conditions. . In order to solve the above-mentioned problems of the traditional technology, a wheat seeding machine equipped with the upper and lower beams and dislocated front and rear with double disc openers has been developed, which solves the problem of installation on the same beam on the tradi...
