Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a mobile under-forest grass planting and tillage burying integrated equipment. Background Art

[0002] Soil tillage for forestry planting is to break the compacted state of the soil by tilling it, making it loose and porous, thereby improving the air permeability and water retention of the soil. This is conducive to the growth and breathing of the tree roots and promotes the root system's absorption of water and nutrients. At the same time, tillage can also turn the nutrients in the deep soil to the surface, providing more abundant nutrients for the growth of trees;

[0003] However, the above patent does not compact the soil in time after plowing, which makes the soil too loose after plowing, thereby accelerating the loss of water and making it difficult to maintain the humidity required for tree growth, resulting in reduced soil bearing capacity and water retention capacity.

[0105] During the process of traveling, the tillage mechanism 20 is used to till the land, the output shaft of the tillage drive motor 225 drives the tillage drive worm 224 to rotate, the tillage drive worm 224 drives the tillage driven worm gear 223 to rotate, and the tillage driven worm gear 223 drives the roller support shaft 221 together with the tillage drive roller shaft 22 and each tillage cutter 220 to rotate, and the soil is tilled by multiple rotating tillage cutters 220;

[0106] The tillage depth is adjusted by using the tillage tilting adjustment mechanism 23. The inner rod of the tilting adjustment driving rod 233 is extended to drive the tilting adjustment support beam 232, together with the tillage mechanism support frame 21 and the tillage driving roller shaft 22, to deflect around the axis of the tillage frame support shaft 211, thereby controlling the height of the tillage driving roller shaft 22 from the ground, thereby adjusting the depth of each tillage cutter 220 inserted into the soil when rotating, and adjusting the tillage depth;

[0107] During the process of moving, the soil after plowing is broken up by the soil block breaking mechanism 50, so that the soil blocks are smaller and more uniform, which is convenient for the next step of sowing;

[0108] During the operation of the soil block crushing mechanism 50, each crushing mechanism support ring 52 is driven by a prior art servo motor independently fixed on the crushing mechanism support shaft 51 to rotate around the axis of the crushing mechanism support shaft 51. With the vertical direction as a reference, the crushing telescopic fixed cylinder 531 is always facing downward, and the crushing mechanism support ring 52 rotates clockwise and counterclockwise periodically around the axis of the crushing mechanism support shaft 51, so that the angle between the axis of the crushing telescopic fixed cylinder 531 and the vertical direction reciprocates between -20° and 20°.

[0109] At the same time, the inner rod of the crushing telescopic driving rod 533 is extended and retracted periodically, with a single stroke of 10 cm. The crushing telescopic driving rod 533 drives the crushing telescopic sliding cylinder 532 together with the crushing driving accommodating shell 54 and the soil crushing cone 55 to reciprocate along the axis of the crushing telescopic fixed cylinder 531;

[0110] The crushing drive motor 542 drives the crushing drive shaft 541 to rotate together with the soil block crushing cone 55, and utilizes the rotation of the soil block crushing cone 55 and the soil block crushing spiral cutting blade 550 to crush the soil blocks after plowing, so that larger soil blocks are broken into smaller soil blocks, and the sizes of the soil blocks are made closer, which is convenient for subsequent sowing and burying;

[0111] During the process of traveling, the grass seed spreading mechanism 30 is used to spread grass seeds on the plowed land. The grass seeds to be spread are stored in the grass seed storage box 313. The particle delivery pump 314 is used to deliver the grass seeds stored in the grass seed storage box 313 to the grass seed delivery pipe 311, and the grass seeds gradually enter the grass seed spreading nozzle 31.

[0112] An air compressor of the prior art is arranged on the top of the rear end supporting chassis 12, and the high-pressure air storage tank of the air compressor is connected to the high-pressure jet connecting pipe 312. The impact control valve 3120 is periodically opened every 2 seconds to allow high-pressure air to enter the grass seed delivery pipe 311 through the high-pressure jet connecting pipe 312. The high-pressure air flow will carry the grass seeds and be ejected from the lower end of the grass seed delivery pipe 311 to sow the grass seeds in the tilled soil.

[0113] The annular connecting tower 32 is used to control the direction of the grass seed delivery pipe 311, so that the grass seeds are more evenly dispersed in the soil;

[0114] The turret rotating support ring housing 322 is driven by a prior art servo motor fixed in the turret fixed support ring 321 through gear transmission to rotate around the vertical axis of the turret fixed support ring 321;

[0115] The turret rotating support ring shell 322 performs periodic clockwise and counterclockwise rotation, so that the grass seed delivery pipe 311 can perform periodic swing around the vertical axis of the turret fixed support ring 321;

[0116] At the same time, the tilting and spreading connecting shaft 325 is driven by a prior art servo motor fixed on the tilting and spreading fixing seat 324 through gear transmission to rotate around the axis of the tilting and spreading connecting shaft 325;

[0117] The axis of the tilting and spreading connecting shaft 325 and the vertical axis of the turret fixed support ring 321 are perpendicular to each other;

[0118] The tilting spreading connecting shaft 325 also rotates periodically clockwise and counterclockwise, so that the grass seed conveying pipe 311 can swing periodically around the axis of the tilting spreading connecting shaft 325. Under the linkage drive of the turret rotating support ring shell 322 and the tilting spreading connecting shaft 325, the direction of the grass seed conveying pipe 311 is periodically adjusted to spread the grass seeds more evenly and dispersedly in the soil.

[0119] During the process of traveling, the grass seed covering mechanism 40 is used to cover the soil after sowing the grass seeds. The bottom of each covering mechanism support plate 41 is rotatably connected to two V-shaped grass seed covering shafts 42, and the grass seed covering shafts 42 are driven to rotate by a motor fixed to the bottom of the covering mechanism support plate 41. The grass seed covering shafts 42 drive the multiple grass seed covering scrapers 420 to rotate together with it. Under the scraping action of the multiple grass seed covering scrapers 420, the soil is moved to the position between the two grass seed covering shafts 42, so that the soil covers the grass seeds sown in the soil.

[0120] The burying lifting mechanism 43 is used to adjust the ground clearance of the burying mechanism support plate 41 and each grass seed burying shaft 42, thereby adjusting the burying thickness. The extension or retraction of the inner rod of the burying lifting driving rod 433 can drive the burying lifting sliding cylinder 432, the burying mechanism support plate 41 and each grass seed burying shaft 42 to move along the vertical axis of the burying lifting fixed cylinder 431 to adjust the ground clearance of the burying mechanism support plate 41 and each grass seed burying shaft 42. The smaller the ground clearance, the more soil the grass seed burying scraper 420 can scrape and the thicker the burying thickness. Conversely, the thinner the burying thickness.

[0121] During the process of traveling, the buried soil is leveled again by the burying auxiliary leveling mechanism 60, so that the buried soil can be more leveled. The auxiliary leveling roller 62 is driven by a motor of the prior art fixed on the auxiliary leveling support frame 61 through a belt drive to rotate, and the auxiliary leveling roller 62 drives the auxiliary leveling brush 620 to rotate together. During the rotation process, the auxiliary leveling brush 620 is used to clean the buried soil, so that the buried soil can be more leveled.

[0122] The inner rod of the buried tilting drive rod 633 extends out to drive the auxiliary leveling support frame 61 together with the auxiliary leveling roller 62 to deflect around the axis of the leveling frame support shaft 611, thereby adjusting the height of the auxiliary leveling roller 62 from the ground, and then adjusting the cleaning force of the auxiliary leveling brush 620 on the soil.
