Description

Technical Field

[0001] The invention relates to the field of ecological restoration, and in particular to a grass seed sowing device for ecological restoration. Background Art

[0002] Ecological restoration usually targets the following types of damaged or degraded land: Mining areas and mining sites: abandoned land, mine pits or ore accumulation areas left after mining. Because mining activities have destroyed the surface cover and soil structure, ecological restoration is needed to restore the ecological function and vegetation cover of the soil. Industrial sites and abandoned construction sites: abandoned industrial land, factory areas or polluted plots left by other industrial activities, such as chemical plant sites, abandoned processing plants, etc., need ecological restoration to reduce pollutant release and restore soil ecological functions. Urban construction and infrastructure projects: ecosystems that are temporarily or permanently damaged during construction, such as construction sites, highway or railway engineering areas, need to be restored and protected through ecological restoration. Land overused by agricultural activities: Long-term agricultural activities may lead to soil impoverishment, increased erosion and loss of biodiversity. Ecological restoration is needed to improve soil quality and restore ecological balance. Forest and wetland degradation: Forest and wetland degradation caused by deforestation, excessive reclamation or ecosystem changes requires ecological restoration to restore the original vegetation type and ecological function. Areas damaged by fire, flood or other natural disasters: Natural disasters such as forest fires and floods may destroy the ecosystem structure and vegetation cover of the land, and ecological restoration is needed to restore the ecological functions and biodiversity of the damaged areas.

[0037] The soil-breaking mechanism 1 includes a frame 11, and a plurality of shoveling pieces 12 are arranged at the front end of the bottom of the frame 11. The soil-turning mechanism 4 is provided with a plurality of groups, and the number of the soil-turning mechanisms 4 corresponds to the number of the shoveling pieces 12. Each group of the soil-turning mechanism 4 includes two power shafts 41. The top of the power shaft 41 is rotatably connected to a slide seat 71 of an adjusting mechanism 7. A plurality of groups of rotating shafts 43 are evenly arrayed from top to bottom on the outer cylindrical surface of the power shaft 41. A soil-turning piece 42 is installed on the rotating shaft 43. Each group of soil-turning pieces 42 and the rotating shaft 43 are arranged in a circular array along the outer cylindrical surface of the power shaft 41. An extrusion shaft 72 is slidably arranged inside the power shaft 41 along the axis of the power shaft 41, and a matching component for cooperating with the soil-turning piece 42 to turn over is provided on the extrusion shaft 72.

[0038] In this embodiment, the mating component on the extrusion shaft 72 includes a mating groove 721 and an adjusting gear 722. The adjusting gear 722 is key-connected to the rotating shaft 43. A tooth groove for mating with the adjusting gear 722 is formed on one side of the mating groove 721. An extrusion disk 73 for lifting and lowering the extrusion shaft 72 is provided at the top of the extrusion shaft 72. A return spring is provided between the bottom of the extrusion shaft 72 and the power shaft 41. The side of the extrusion disk 73 is fixedly connected to the fixed seat 76. The fixed seat 76 is fixedly connected to the frame 11. A support spring 77 is provided between the slide seat 71 and the fixed seat 76. The upper end of the extrusion shaft 72 passes through the slide seat 71, and sliding components are provided on both sides of the slide seat 71.

[0039] In this embodiment, the sliding assembly includes a first limiting slide rail 74 and a second limiting slide rail 75. The first limiting slide rail 74 and the second limiting slide rail 75 limit the sliding of the slide seat 71. An extrusion groove 741 is formed on the inner bottom surface of the first limiting slide rail 74. The top surfaces of the two power shafts 41 are respectively fixedly connected with a synchronous gear 44 and a movable gear 441. The synchronous gear 44 and the movable gear 441 are meshed with each other. An extrusion rod 742 is slidably connected to the bottom surface of the movable gear 441 on the slide seat 71. A wave groove 743 is formed on the bottom surface of the movable gear 441 at a position corresponding to the extrusion rod 742. When the slide seat 71 drives the synchronous gear 441 to move, the sliding assembly 71 is provided with a plurality of movable gears 441, and the movable gear 441 is provided with a plurality of movable gears 441. When the wheel 44 and the movable gear 441 move backward, the squeezing rod 742 is squeezed and moved upward by the squeezing groove 741. At this time, the squeezing rod 742 moves upward and cooperates with the wave groove 743 on the bottom surface of the movable gear 441, thereby generating wave jumping. The movable gear 441 drives the power shaft 41 to jump up and down, and then drives the soil-turning piece 42 to jump up and down. The power shaft 41 and the soil-turning piece 42 corresponding to the synchronous gear 44 will not jump up and down, so that the soil blocks between the two power shafts 41 are cut and then cooperate to jump up and down, thereby improving the crushing effect and eliminating the problem of the gap between the upper and lower parts becoming larger when the rotating shaft 43 flips the angle.

[0040] In this embodiment, the synchronous gear 44 cooperates with the transmission mechanism 6, and the transmission mechanism 6 includes a passive sprocket 65. The synchronous gear 44 is fixedly connected to the passive sprocket 65. A driving sprocket 63 is arranged on the front side of the passive sprocket 65. The passive sprocket 65 and the driving sprocket 63 are connected by chain transmission. A tension adjustment component 64 for adjusting the tension of the chain is arranged between the passive sprocket 65 and the driving sprocket 63. The tension adjustment component 64 is fixedly connected to the slide seat 71. A worm wheel 62 is connected to the driving sprocket 63, and a worm 61 is matched on the side of the worm wheel 62.

[0041] In this embodiment, the sowing mechanism 3 includes a drop tube 31, a distribution tube 32 is connected to the bottom of the drop tube 31, a storage barrel is arranged on the top of the drop tube 31, a distribution barrel 35 is rotatably connected inside the distribution tube 32, a passive gear 37 is arranged at the center of the distribution tube 32 to drive the distribution barrel 35 to rotate, a sealing box 34 is arranged outside the passive gear 37, a discharge tube 33 is installed at the bottom of the distribution tube 32, a discharge port 36 is formed on the distribution barrel 35 corresponding to the position of the discharge tube 33, a spiral piece 351 is formed inside the distribution barrel 35, after the distribution barrel 35 and the spiral piece 351 are driven to rotate, the grass seeds can flow to both sides through the guide of the spiral piece 351, flow out from the discharge port 36 to the inside of the discharge tube 33, and then fall out of the discharge tube 33 for sowing.

[0042] In this embodiment, the spiral blade 351 is a two-stage symmetrical spiral blade, and the spiral blade 351 is symmetrically located with respect to the blanking tube 31 .

[0043] In this embodiment, the power mechanism 5 includes an active bevel gear 51, a motor 53 is connected to the power end of the active bevel gear 51, passive bevel gears 52 are respectively matched on both sides of the bottom of the active bevel gear 51, and the two passive bevel gears 52 are respectively fixedly connected to the passive gear 37 and the worm 61.

[0044] In this embodiment, the turning angle of the soil turning piece 42 is 0° to 45°.

[0045] In this embodiment, a cone is installed at the bottom of the power shaft 41 , and a dust cover is provided at the top of the power shaft 41 outside the transmission mechanism 6 and the adjustment mechanism 7 .

[0046] In this embodiment, moving wheels 13 are provided at both ends of the frame 11 , and the soil leveling mechanism 2 includes a rake 21 , which is provided at the rear end of the frame 11 , and a soil leveling roller 22 is installed at the rear end of the rake 21 .

[0047] The working principle is as follows: according to the land to be sown, the hardness of the support spring 77 is adjusted, and then the device is towed by a tractor or other equipment to sow grass seeds.

[0048] During the forward movement, the shovel 12 will first break up the compacted soil and turn it over. After turning it over, the equipment continues to move forward. At this time, the power shaft 41 contacts the soil blocks that have been broken for the first time. The soil blocks and the soil generate a resistance to the power shaft 41. After the resistance hits the power shaft 41 and the turning piece 42, the power shaft 41 drives the top slide 71 to move backward, and at the same time the motor 53 provides power.

[0049] After the power is transmitted through the worm 61, the worm wheel 62, the active sprocket 63, and the passive sprocket 65, the synchronous gear 44 and the movable gear 441 simultaneously drive the power shaft 41 and the rotating shaft 43 to rotate. At this time, because the sliding seat 71 does not slide far to the rear, the rotating shaft 43 is in an initial flipped state, and the two groups of rotating shafts 43 impact and rotate with each other to crush the compacted soil blocks, thereby ensuring the softness of the soil blocks after crushing. At the same time, the rear side dividing barrel 35 is also driven to rotate. After the dividing barrel 35 and the spiral blade 351 are driven to rotate, the grass seeds can flow to both sides through the guide of the spiral blade 351, flow out from the discharge port 36 to the inside of the discharge pipe 33, and then fall out of the discharge pipe 33 for sowing. After sowing, it is leveled by the rake 21 and the leveling roller 22.

[0050] When the soil is severely compacted during the journey, the shovel member 12 will encounter a slightly larger volume of soil blocks after breaking, and the resistance to the power shaft 41 will increase. The resistance transmitted to the slide seat 71 by the power shaft 41 will also increase, and the slide seat 71 will slide backward. At this time, the extrusion plate 73 on the top will apply pressure to the extrusion shaft 72 on the inclined surface, and the extrusion shaft 72 will move downward inside the power shaft 41. During the downward movement, the tooth groove inside the matching groove 721 cooperates with the adjusting gear 722, and the adjusting gear 722 drives the extrusion shaft 72 to flip through the extrusion plate 73, and the extrusion shaft 72 flips to a state tending to be straight (such as Fig.14 As shown in the figure, at this time, the soil turning piece 42 changes the original beating and crushing state of the soil blocks to the cutting and crushing state, thereby improving the crushing effect. At the same time, when the sliding seat 71 drives the synchronous gear 44 and the movable gear 441 to move backward, the squeezing rod 742 is squeezed and moved upward by the squeezing groove 741. At this time, the squeezing rod 742 moves upward and cooperates with the wave groove 743 on the bottom surface of the movable gear 441, thereby generating wave jumping. The movable gear 441 drives the power shaft 41 to jump up and down, thereby driving the soil turning piece 42 to jump up and down. The power shaft 41 and the soil turning piece 42 corresponding to the synchronous gear 44 will not jump up and down, so that the soil blocks between the two power shafts 41 are cut and then cooperate with the up and down jumping, thereby improving the crushing effect. At the same time, the problem of the gap between the upper and lower parts becoming larger after the rotating shaft 43 flips the angle is eliminated, thereby ensuring the effect of soil block crushing and the softness of the soil. After passing through this hard soil area in the later stage, the sliding seat 71 is supported and reset by the support spring 77, and the rotating shaft 43 is also reset, and the subsequent soil blocks are crushed by beating.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
