Description

Technical Field

[0002] Corn is an important food crop and feed crop. With the development of corn, mechanized planting has been adopted, so corn sowing equipment is needed. When the existing corn sowing equipment is in use, the sowing device does not have the function of synchronous fertilization. The growth of crops requires certain nutrients. Since synchronous fertilization cannot be performed, manual construction is required later. The existing patent with authorization announcement number CN117837345B discloses a corn sowing equipment with synchronous fertilization function. The device can release fertilizer while sowing corn. Although the synchronous operation of sowing and fertilizing is completed here, this method of fertilization will mix with the seeds and easily cause seed damage. Generally, fertilizer is applied around the seeds or seedlings, and fertilizer cannot be applied directly on the seeds or the roots of the seedlings, which will cause the problem of burning the seedlings. In addition, the equipment cannot adjust the single sowing amount of fertilizer and seeds.

The speed change structure 200 includes a first support plate 203 and a second support plate 216 symmetrically arranged at the upper end of the seeding frame 100, a transmission sleeve 213 is rotatably provided on the upper end of the second support plate 216, a driving pulley 214 is provided at the end of the transmission sleeve 213, and the driving pulley 214 is connected to the driven pulley 305 through a transmission belt 215, a transmission shaft 211 is slidably provided in the transmission hole at the end of the transmission sleeve 213, a limiting protrusion 212 is provided on the outer side of the transmission shaft 211, and a limiting groove matching the limiting protrusion 212 is provided on the inner wall of the transmission sleeve 213, and the limiting groove and the limiting protrusion 212 match so that the transmission sleeve 2 13 and the transmission shaft 211 can only slide relative to each other and cannot rotate relative to each other. A friction wheel 205 is provided at the end of the transmission shaft 211. The lower side of the friction wheel 205 is in friction contact with the outer upper surface of the friction disc 204. The lower end of the friction disc 204 is connected to the transmission shaft 201. The transmission shaft 201 is connected to the second output end of the drive motor group 106. Under the drive of the drive motor group 106, the transmission shaft 201 drives the friction disc 204 to rotate. The friction force between the friction disc 204 and the friction wheel 205 drives the friction wheel 205 to rotate. The friction wheel 205 drives the drive pulley 214 to rotate through the transmission shaft 211 and the transmission shaft sleeve 213, thereby providing power for blanking; The transmission shaft 211 is connected to a centrifugal adjustment member for driving it to move along the surface of the friction disk 204.

The threaded block 210 and the first screw 208 are driven to rotate relative to each other by the first handle 207. Under the action of the thread, the threaded block 210 will move horizontally along the centrifugal guide rod 209, driving the friction wheel 205 to move along the diameter direction of the friction disk 204, providing power for transmission ratio adjustment; The center of the friction disc 204 is provided with a central rotating block 202. When the friction wheel 205 moves to the center of the friction disc 204 and contacts the central rotating block 202, the friction wheel 205 will not rotate. At this time, even if the equipment moves, the sowing operation will not be carried out. The groove depth adjustment mechanism includes an adjustment cavity 311 arranged inside the rotating inner column 317, a cross 312 is provided at the port position of the adjustment cavity 311, a second screw 314 is rotatably provided on the cross 312, a second handle 315 is provided at the outer end of the second screw 314, and an adjustment center block 308 is threadedly connected to the inner end of the second screw 314.

Under the action of the thread, the adjusting connecting rod 313 will slide along the guide inner rod 316, so that the adjusting center block 308 moves along the axis of the rotating inner column 317. At this time, the adjusting connecting rod 313 will pull the loading slider 309 to slide inside the loading chute 310 to adjust the filling depth. An extrusion spring can also be provided between the end of the adjusting center block 308 and the rotating inner column 317. The spring can make the adjusting center block 308 and the second screw 314 in a pre-tightened state. The groove width of the loading chute 310 is 2 cm, and the depth adjustment range is 0.5-3 cm. The groove depth adjustment mechanism can make the single feeding amount linearly adjusted between 5-30 grains of corn / 10-60g of fertilizer; The soil covering component includes a second telescopic push rod 500 provided on the armrest 107, and a soil covering beam 501 is provided at the output end of the second telescopic push rod 500. The soil covering beam 501 has symmetrically eight-shaped soil covering inclined plates 502 at both ends.

The lifting guide rods 402 are slidably arranged with the perforations on the mounting side plate 401. Under the drive of the first telescopic push rod 400, the soil turning block 403 will slide up and down along the lifting guide rods 402 and the perforations, thereby driving the soil turning block 403 to adjust the soil turning depth; The walking wheel group includes a support leg 101 symmetrically at the bottom of the seeding rack 100, and a wheel axle 104 is rotatably provided at the lower end of the support leg 101. Traveling wheels 102 are provided at both ends of the wheel axle 104, and a driven gear 103 is sleeved on one of the wheel axles 104. A driving motor group 106 is provided at the bottom of the seeding rack 100, and a first output end of the driving motor group 106 is connected to a driving gear 105. The driving gear 105 and the driven gear 103 are engaged with each other.

[0029] Working principle: In actual use, corn seed box 300 and fertilizer box 301 are loaded, and the groove depth adjustment mechanism is adjusted as needed to adjust the ratio of corn and fertilizer; The equipment is driven to move by the traveling wheel set. When moving, the soil turning component will form a sowing groove on the traveling path. The material discharge driving component will drive the two rotating inner columns 317 to rotate. When the material loading chute 310 on the rotating inner column 317 is facing upward, the material will be received. When the material loading slider 309 rotates to the bottom, the fully loaded corn or fertilizer will fall down and then flow down along the discharge barrel 304 respectively. The fertilizer enters the guide tube 318. When the fertilizer in the guide tube 318 flows down along the guide tube 318 and enters the guide outer cylinder 319, the weight of the fertilizer will impact the distribution plate 321, thereby driving the distribution plate 321 to rotate. The rotating distribution plate 321 will help disperse the fertilizer. The dispersed fertilizer will fall along the gap between the guide inner cylinder 322 and the guide outer cylinder 319 to form area B, while the seeds will fall along the sowing inner cylinder 323 to form area A, completing a single sowing and fertilization. As the equipment moves, the soil covering inclined plates 502 will move the soil on both sides toward the middle so that the soil covers the seeds.
