Abstract
A seven-rod profile modeling seeding monomer with narrow row ploughing function is mainly formed by hinging a rear connecting plate, an upper connecting rod, a fixed connecting rod, a lower connecting rod, a front profile modeling wheel, a front rocker, a profile modeling lower pull rod, a rear profile modeling rocker, a rear profile modeling press wheel and a thread adjusting device together through a pin shaft and the like; the furrow opener is fixedly installed with the rear connecting rod, moves up and down along with the main body and the soil-entering angle does not change in the working process; the length of the adjustable connecting rod can be changed by adjusting the screw adjusting device through the adjusting handle, so that the front rocker and the rear rocker rotate relatively to enable the front profiling wheel and the rear profiling wheel to move up and down relative to the position of the furrow opener, the sowing depth is adjusted and set, the qualified precision of the normal position profiling sowing depth can be reached, and the requirement of narrow-row sowing can be realized.
Description
Technical Field
The invention belongs to the field of agricultural machinery, and mainly relates to a narrow row ploughing seven-rod profiling seeding monomer.
Background
At present, most of seeding units for domestic and foreign seeding machines are parallel four rods and are matched with a press wheel to realize front profiling, rear profiling and normal profiling. The front or back profiling causes uneven seeding depth of the seeds of the sown crops and even seed airing phenomenon due to the defect of advanced or delayed profiling; the normal copying seeding monomer has complex structure, large volume, heavy weight and overlarge transverse size, and can not meet the requirement of seeding narrow-row crops.
Disclosure of Invention
Aiming at the problems, the invention creatively designs the narrow-row ploughing seven-rod copying seeding monomer, which can meet the qualified precision of the normal copying seeding depth and can also realize the requirement of narrow-row seeding. A seven-rod profile modeling seeding monomer with narrow row ploughing function is mainly formed by hinging a fixed connecting rod, an upper connecting rod, a lower connecting rod, a rear connecting rod, an adjustable connecting rod, a thread adjusting device, an adjusting handle, a rear profile modeling wheel, a front rocker, a furrow opener and a rear rocker together through a pin shaft and the like; the furrow opener is fixedly installed with the rear connecting rod, moves up and down along with the main body and the soil-entering angle does not change in the working process; the length of the adjustable connecting rod can be changed by adjusting the thread adjusting device through the adjusting handle, so that the front rocker and the rear rocker rotate relatively, the front profiling wheel and the rear profiling wheel move up and down relative to the position of the furrow opener, and the sowing depth is adjusted and set.

Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings.
A seven-rod copying seeding monomer with narrow row ploughing function is mainly formed by hinging a rear connecting plate 2, an upper connecting rod 3, a fixed connecting rod 4, a lower connecting rod 5, a front copying wheel 6, a front rocker 7, a copying lower pull rod 9, a rear copying rocker 10, a rear copying press wheel 11 and a thread adjusting device 13 together through a pin shaft and the like; the specific arrangement scheme is as follows: the seed sowing device is characterized in that a seed sowing device 15 is fixedly connected with a rear connecting plate 2 of a parallel four-bar mechanism, a seed box 1 is assembled on the upper portion of the seed sowing device 15, the seed box 1 is communicated with the seed sowing device 15, the front end of a screw rod adjusting device 13 is fixedly connected with the seed sowing device 15, the rear end of the screw rod adjusting device is hinged with a rear profiling rocker 10, the lower portion of the rear connecting plate 2 of the parallel four-bar mechanism is hinged with a front profiling rocker 7, the front profiling wheel 6 is assembled at the front end of the front profiling rocker 7, the rear end of the front profiling rocker is hinged with a profiling lower pull rod 9, a rear profiling press.
During operation, firstly, according to the soil and land conditions in a seeding field, the screw adjusting device 13 is utilized to drive the back profiling press wheel 11 to move up or down, and the press force and the seeding depth with the ground are adjusted. The furrow opener 8 is fixedly connected with the rear connecting rod 9, moves up and down along with the main body and the soil-entering angle does not change in the working process; the length of the device can be adjusted by adjusting the threaded adjustment means 13. The front and rear contour wheels are adopted for cooperation in contour, so that the normal-position contour precision can be achieved, the transverse distance of the single body is effectively shortened, and seeding with the minimum row spacing of 120mm can be realized.
