Description

Technical Field

[0001] The present 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 in forestry planting is a process that breaks up soil compaction, making it loose and porous, thereby increasing its air permeability and water retention. This facilitates the growth and respiration of tree roots, promoting their absorption of water and nutrients. Tillage also brings nutrients from deep soil layers to the surface, providing a richer supply of nutrients for tree growth.

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

The tillage driven worm gear 223 then drives the roller support shaft 221, the tillage drive roller shaft 22, and each tillage cutter 220 to rotate together. The soil is tilled by the rotating tillage cutters 220.

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

[0107] During the process of moving, the soil clod breaking mechanism 50 is used to break up the plowed soil, making the soil clods smaller and more uniform, which is convenient for the next step of sowing.

[0108] During operation of the soil crushing mechanism 50, each crushing mechanism support ring 52 is driven by a prior art servo motor independently fixed to 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. The crushing mechanism support ring 52 rotates periodically clockwise and counterclockwise around the axis of the crushing mechanism support shaft 51, causing the angle between the axis of the crushing telescopic fixed cylinder 531 and the vertical direction to reciprocate between -20° and 20°.

[0109] At the same time, the inner rod of the crushing telescopic drive rod 533 is periodically extended and retracted, with a single stroke of 10 cm. The crushing telescopic drive rod 533 drives the crushing telescopic sliding cylinder 532, together with the crushing drive housing 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 crushing cone 55. The soil clods after plowing are crushed by the rotation of the soil crushing cone 55 and the soil crushing spiral cutting blade 550, so that larger soil clods are broken into smaller soil clods and the sizes of the soil clods are made closer, which is convenient for subsequent sowing and burying.

[0111] During the journey, 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 granular delivery pump 314 delivers the grass seeds stored in the grass seed storage box 313 to the grass seed delivery pipe 311. The grass seeds gradually enter the grass seed spreading nozzle 31.

[0112] A conventional air compressor is installed on top of the rear support chassis 12. 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, allowing 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, sowing the grass seeds into the plowed 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 housing 322 rotates periodically clockwise and counterclockwise, so that the grass seed delivery pipe 311 can swing periodically 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, causing the grass seed conveying pipe 311 to periodically swing around the axis of the tilting spreading connecting shaft 325. Driven by the turret rotating support ring 322 and the tilting spreading connecting shaft 325, the orientation of the grass seed conveying pipe 311 is periodically adjusted, so that the grass seeds are more evenly dispersed in the soil.

[0119] During the movement, the grass seed covering mechanism 40 is used to cover the soil after the grass seeds are sown. 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 them. 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 the grass seed burying shafts 42, thereby adjusting the burying thickness. The extension or retraction of the inner rod of the burying lifting drive rod 433 can drive the burying lifting sliding cylinder 432, the burying mechanism support plate 41 and the grass seed burying shafts 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 the grass seed burying shafts 42. The smaller the ground clearance, the more soil can be scraped by the grass seed burying scraper 420, and the thicker the burying thickness. Conversely, the thinner the burying thickness.

[0121] During the moving process, 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 conventional motor fixed to the auxiliary leveling support frame 61 through a belt drive, 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 is extended 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, adjust the height of the auxiliary leveling roller 62 from the ground, and then adjust the cleaning force of the auxiliary leveling brush 620 on the soil.
