[0022] As Figs. 1-3 shown, the utility model discloses a novel spreading structure for topdressing seeding equipment, including whole machine connecting piece 1, compression assembly 2 and spreading assembly 3, and whole machine connecting piece 1 and compression assembly 2 are arranged at the both sides of spreading assembly 3 respectively, spreading assembly 3 is provided with spreading frame 31 and front and rear staggered disc 32, and front and rear staggered disc 32 is arranged below spreading frame 31, spreading frame 31 is provided with feeding hole 33 and first adjuster 34, feeding hole 33 penetrates spreading frame 31 to the inside of front and rear staggered disc 32, compression assembly 2 is provided with double compression structure 21, and double compression structure 21 is connected with compression wheel 22 at one end, and second adjuster 23 is arranged between compression wheel 22 and double compression structure 21, and the other end of double compression structure 21 is connected with spreading frame 31.
[0023] The double-rolling structure 21 comprises a rolling wheel connecting piece 211 and a rolling fixing piece 212. One end of the rolling wheel connecting piece 211 is arranged at the center of the rolling wheel 22, and the other end of the rolling wheel connecting piece 211 is arranged with a fixing column 213 close to the spreading frame 31. The fixing column 213 penetrates the rolling fixing piece 212 and is connected with the rolling wheel connecting piece 211. The other end of the rolling fixing piece 212 is connected with the spreading frame 31. The double-rolling structure 21 can provide greater pressure, so that the soil where the fertilizer or seeds have been spread is more compacted, which helps the seeds and fertilizer to contact with the soil, promotes the seed to absorb water and root, and helps the fertilizer to mix with the soil fully, improving the internal environment of the soil. The rolling wheel 22 is arranged with a soil scraping piece 6 at the tail end. The bottom end of the soil scraping piece 6 is arranged as an outward inclined shape. The outward inclined soil scraping piece 6 can scrape off the soil adhered to the wheel when the rolling wheel 22 rolls, preventing the soil from accumulating on the wheel and keeping the wheel clean and working normally.
[0024] The differential connecting piece 35 is arranged in the middle of the inside of the front-rear staggered disc 32. The two ends of the differential connecting piece 35 are respectively connected with the inside center of the front-rear staggered disc 32. The outside center of the front-rear staggered disc 32 is respectively arranged with a disc outside fixing flange 36. The inside of the front-rear staggered disc 32 is arranged with a spreading disc 37 below the corresponding feeding hole 33. The spreading disc 37 is arranged with a connecting rod 38 fixed on the spreading frame 31. The design of the front-rear staggered disc 32 can make the fertilizer more dispersed when applied, avoiding concentrated accumulation, so as to achieve more uniform fertilization effect. The one end of the disc outside fixing flange 36 close to the front-rear staggered disc 32 is arranged as a circular ring shape. The design of the circular ring shape can help to more evenly distribute the stress applied by the fixing bolts or screws, reduce stress concentration, help to improve the strength and rigidity of the flange, so that it can withstand greater load to improve the stability and durability of the structure.
[0025] The first adjuster 34 and the second adjuster 23 are respectively arranged with an adjusting spring 4 and an adjusting knob 5. The first adjuster 34 is used to adjust the rotational inertia of the front-rear staggered disc 32, and the second adjuster 23 is used to adjust the rolling pressure of the rolling wheel 22. The design of adjusting the front-rear staggered disc 32 through the first adjuster 34 allows the operator to more easily adjust the fertilization and seeding depth and amount according to the actual soil environment, so as to adapt to the growth requirements of different crops and effectively improve the soil environment by optimizing the fertilization position according to the soil condition, so that the soil can fully absorb the fertilizer. The design of adjusting the rolling pressure of the rolling wheel 22 through the second adjuster 23 increases the flexibility of the rolling wheel 22 system, so that it can adapt to the planting of various crops and soil types, without the need to replace the entire rolling wheel 22 or other parts. The pressure of the rolling wheel 22 can be adjusted in real time, which can optimize the working efficiency of the seeding machine and reduce the rework and repair caused by improper pressure.
[0026] In the specific implementation process, the whole machine connecting piece 1 is connected with the topdressing machine or the seeding machine, the feeding hole 33 is connected with the fertilizer hopper of the whole machine, the whole machine drives the structure to move forward, the front and rear staggered discs 32 of the material spreading assembly 3 enter the soil to form the fertilization or seeding pit, the fertilizer or seeds are uniformly spread to the deep holes divided by the front and rear staggered discs 32 through the feeding hole 33 to the material spreading disc 37 in the front and rear staggered discs 32, and then the pressing wheel 22 rolls and compacts the soil on both sides to the middle, fills the deep holes on both sides which have been spread with the fertilizer or seeds; based on the loose and compact soil, the rotary inertia and rolling pressure of the front and rear staggered discs 32 and the pressing wheel 22 can be adjusted through the first adjuster 34 and the second adjuster 23.
[0027] Therefore, the novel material spreading structure for the topdressing and seeding equipment adopting the above structure is suitable for various soil environments, can control the fertilization or seeding depth, and improves the uniform spreading ability and efficiency in the fertilization and seeding process.
[0028] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model and not to limit them, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solutions of the utility model can still be modified or replaced, and these modifications or replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the utility model.
