Embodiment Construction

[0014] exist Figure 1~2 In the shown embodiment: the support frame I2 and the support frame II5 are mainly composed of a sleeve 12, a telescopic shaft 13, a spring 14 and a pressing wheel 15. A shaft shoulder is provided on the telescopic shaft 13, and the end close to the shaft shoulder is embedded in a spring 14, the other end of telescopic shaft 13 is connected with profiling wheel; A long slot hole 10 is set at the front of the beam 1, and a round through hole 11 is set at the rear. The support frame I2 is connected to the beam 1 through the pin shaft I3 and the bushing 4, and the bushing 4 is embedded in the slotted hole 10. One end of the pin shaft passes through the bushing 4, and the other end is fixedly connected with the support frame I2; the support frame II5 is hinged to the beam 1 through the pin shaft II6, wherein one end of the pin shaft II6 passes through the round through hole 11 at the rear of the beam 1, and the other end It is fixedly connected with the s...

Abstract

The invention discloses a seeder profiling mechanism, comprising a beam, a support frame I, a pin shaft I, a shaft sleeve, a support frame II, a pin shaft II, a pin shaft III, a pressure spring and a seeding pipe. The seeder profiling mechanism is characterized in that a slotted hole is formed at the front part of the beam; a round through hole is formed at the rear part; the support frame I and the support frame II are respectively hinged to the beam; through holes are respectively formed at the middle and upper parts of the support frame I and the support frame II; the pin shaft III orderly passes through the through holes of the support frame I and the support frame II to connect the support frame I and the support frame II; the pressure spring is arranged between the pin shaft III and the beam; one end of the pressure spring is fixed below the beam; the other end is fixed on the pin shaft III; and the seeding pipe is fixedly arranged between the slotted hole of the beam and the round through hole. The seeder profiling mechanism is strong in practicability and good in profiling effect.

Description

technical field [0001] The invention relates to a profiling mechanism of a seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] Sowing is the main agricultural equipment now, and it plays a major role in the current agricultural production. The current crop planting has basically realized mechanized sowing. The sowing depth of seeds will greatly affect the germination rate, growth, yield, etc. of crops. The profiling mechanism is the main part of the seeder, and its profiling effect will affect the sowing depth, thereby affecting the germination rate, growth, and yield of seeds. There are generally three types of profiling mechanisms commonly used now, such as parallel four-bar linkage mechanism, single-link hinge mechanism, and multi-rod multi-degree-of-freedom mechanism. These mechanisms have the problem that the profiling is too sensitive or the profiling is advanced or lagging, or the opening angle of the opener is rigid...
