Detailed ways

As shown in Figures 1 and 2, a rapeseed seed drill with less tillage and fertilization matched with a walking tractor has a transmission box 19 connected to the front end of the main frame 9, and a power input gear 21 and a power input gear 21 are installed on the transmission shaft 20 fixed in the transmission box. The power output gear is arranged on the gear connected on the rotary tiller shaft 18 at the lower end of the transmission box and meshes with the power output gear on the transmission shaft through the intermediate gear. Four rotary tillage discs 2 are arranged at intervals on the rotary tillage shaft, and three rotary tiller knives 1 are respectively assembled on both sides of the rotary tiller discs at 120 degrees. The rear end of the main frame is provided with a rotary tillage adjustment mechanism composed of ground wheels, connecting plates, fixed plates, adjusting rods, springs and adjusting nuts. The adjusting rod 10 installed between the connecting plate 15 hinged between the ground wheel 16 shaft and the intermediate shaft installed under the main frame and the fixed plate 12 fixed on the rear end of the main frame is covered with a spring 14, stretching out from the fixed plate The adjustment rod on the end face is threadedly connected with the adjustment nut 11. The height of the ground wheel 16 can be changed by turning the adjusting nut, and the spring on the adjusting rod has a shockproof effect on the one hand, and on the other hand can improve the applicability of the ground wheel in high and low areas. The main frame is respectively equipped with a seed box 6 and a fertilizer box 7. The four outlets arranged horizontally at the bottom of the seed box and the fertilizer box are respectively set on the four seed metering devices on the sowing shaft and successively set on the sowing shaft. The receiving flanges in the four fertilizers on the fertilization shaft are correspondingly connected.

The seed meter and the fertilizer applicator are respectively composed of a material receiving box and a sheave (see Figure 4). The material receiving box 26 is provided with "+" shaped vertical and horizontal through holes, and the upper and lower ends of the vertical through holes are respectively set. There are receiving flange and discharging hopper. The sheave 27 is tubular, and its outer edge is matched with the transverse through hole in the receiving box, and the outer edge in the middle is provided with 2-4 blind holes with diameters and radial spacings ranging from small to large, and the inner edge of the sheave The hole is matched with the sowing shaft or the fertilization shaft 29 and fixed.

The sowing shaft installed on the main frame plate and one end of the fertilizing shaft are respectively connected with the adjustment handle 31, and the other end is respectively equipped with the sowing sprocket 5 and the fertilizing sprocket 8, and the sowing sprocket and the fertilizing sprocket are installed on the The second sprocket wheel in the double sprocket wheel 13 that is affixed on the intermediate shaft one end below the main frame is connected, and the first sprocket wheel in the double sprocket wheel is connected with the sprocket wheel 17 that is affixed on one side of the ground wheel shaft through the first chain.

The adjusting handle 31 is composed of a turntable, a hollow screw connected to one end of the turntable, and a side plate 33 provided with an internal threaded hole matched with the hollow screw (see FIG. 4 ). When installing, first insert one end of the sowing shaft or fertilizing shaft from one end of the hollow screw of the adjustment handle to the cavity in the turntable, insert the key 32 into the through hole opened at the port of the sowing shaft or fertilizing shaft, and insert the sowing shaft or fertilizing shaft The shaft is connected and fixed with the turntable, and then the hollow screw rod connected to one end of the turntable is matched with the internal thread hole of the side plate, and then the side plate and the main frame plate are connected and fixed by fasteners.

The discharge hoppers in the seed metering device and the fertilizer applicator are respectively connected to the inlet ends of the seed metering pipe 3 and the fertilization pipe 4 fixed on the rod 24 through flexible hoses (see FIG. 3 ). The tops of the seeding pipe and the fertilizing pipe are clamped by front and rear splints 23 respectively, and the front and rear splints are connected and fixed on the bar by U-shaped bolts 25 and nuts 22 . Loosen the nut, you can move left and right, up and down to adjust the line spacing of the seeding pipe or fertilization pipe and the height from the ground.

The soil-entry ends of the seeding pipe 3 and the fertilizing pipe 4 all adopt sharp angles, so as to ditch for seeding and fertilization. The inner cavity with sharp angles is provided with a baffle inclined from top to bottom, so that the dropping point of seeds and fertilizers is relatively stable.

Its working process: the power output by the tractor passes through the power input gear 21 fixedly connected to the transmission shaft 20 in the transmission box 19, and the power output gear arranged on the transmission shaft passes through the intermediate gear and the gear connected to the rotary tiller shaft 18. The tiller shaft, the rotary tiller blade 1 on the rotary disc 2 installed on the rotary tiller shaft is the rotary tiller; at the same time, the ground wheel 16 is rotated by its friction with the ground during the process of advancing with the walking tractor. The sprocket 17 on the ground wheel shaft drives the first sprocket in the double sprocket 13 to rotate through the first chain, and the second sprocket in the double sprocket drives the sowing sprocket 5 and the fertilization sprocket 8 to rotate through the second chain simultaneously , so that the seed meter and fertilizer applicator set on the sowing shaft and the fertilization shaft rotate simultaneously for seed metering and fertilization; rotate the adjustment handle 31, and adjust the blind hole on the outer edge of the groove wheel 27 in the seed meter or fertilizer applicator The position in the vertical through hole of the material receiving box 26 can realize the control of the amount of seeding and fertilization.
