Description

Technical Field

[0001] The invention belongs to the technical field of vegetation restoration devices for desertified grasslands, and in particular relates to a vegetation restoration and ecological conservation device for desertified grasslands. Background Art

[0002] Grassland degradation is a retrograde ecological succession caused by unreasonable management and excessive utilization under fragile ecological and geographical conditions, which leads to the succession process of vegetation productivity decline, biological composition replacement, soil degradation, hydrological cycle system changes, and near-surface microclimate environment deterioration. Therefore, it is necessary to take measures to protect and restore grassland vegetation. Unlike vegetation restoration in other areas, when grasslands are restored, because grasslands generally lack the protection of trees, when the vegetation on the ground disappears, the land is prone to desertification. Therefore, when restoring grassland vegetation, it is generally necessary to use grass grids to fix the sand to prevent the sand from moving around under the action of wind. Finally, grass seeds are used to plant in the sand area fixed by the grass grids to achieve the purpose of vegetation restoration.

[0003] When the existing straw grid paving machine is performing the straw grid paving operation, some straw bale materials are relatively loose, and the existing straw grid paving machine lacks a suitable material shifting component, which results in the straw grid being easily discontinuous when the straw laid on the ground is pressed into the sand by the straw pressing disc, affecting the fixing effect of the straw grid on the sand, and further affecting the subsequent sowing effect of grass seeds.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] The present invention provides Figures 1 to 7The desertified grassland vegetation restoration and ecological conservation device shown in the figure includes a shell 1, a seeder 2 is connected to the rear side of the shell 1, a towing hook 3 is connected to the front side of the shell 1, rollers 4 are installed on both sides of the shell 1, and two driving rollers 5 are vertically rotatably connected between the inner walls on both sides of the shell 1. The two driving rollers 5 are distributed front and back, and two groups of conveying components are connected between the two driving rollers 5. The conveying components include a plurality of feeding belts 15 arranged side by side, and the distance between two adjacent feeding belts 15 is the same. The feeding belt 15 is sleeved between the two driving rollers 5, and the feeding belt 15 The outer surface of the housing 1 is evenly provided with first convex teeth 16, the material storage plate 7 is located at the rear side of the top of the feeding belt 15, and two pressure rollers 6 are vertically rotatably connected between the inner walls of the two sides of the housing 1. The two pressure rollers 6 are distributed front and back, and the two pressure rollers 6 are located at the top of the driving roller 5. The pressure roller 6 located at the front side is directly on the top of the front driving roller 5, and the pressure roller 6 located at the rear side is located between the two driving rollers 5. Two groups of pressing components are connected between the two pressure rollers 6, and the pressing components include a plurality of pressing belts 17 arranged side by side, and the plurality of pressing belts 17 are distributed one by one on the plurality of feeding belts 1 5, the distance between two adjacent pressing belts 17 is the same, the pressing belt 17 is sleeved between the two pressing rollers 6, and the outer side of the pressing belt 17 is evenly provided with second convex teeth 18, and the rear side of the pressing roller 6 located at the rear side is provided with an arc-shaped storage plate 7, and the position of the storage plate 7 facing the two pressing components is penetrated with a strip hole, the two sides of the storage plate 7 are fixedly connected to the inner walls of the shell 1 on both sides, and two rolls of straw bales 8 are placed on the storage plate 7, the top of the shell 1 is provided with a discharge hole, and a cover plate 9 is hinged in the discharge hole, and the top of the front side of the storage plate 7 is connected to the discharge hole An inclined baffle 10 is connected, a material-diverting assembly is arranged on the front side of the baffle 10, a grass-pressing assembly is arranged on the rear side of the material storage plate 7, first gears 11 are fixedly sleeved at both ends of the driving roller 5 located on the front side, a second gear 12 is meshed on the top of the first gear 11, a fixed shaft 13 is vertically inserted through the axis of the second gear 12, and the fixed shaft 13 is vertically rotatably mounted on the side wall of the housing 1, a first transmission belt 14 is connected between the fixed shaft 13 and the end of the pressing roller 6 located on the front side, and the pressing belt 17 has the same width as the feeding belt 15, and the two can fit together; Before laying the grass grid, the housing 1 is first connected to the tractor (not shown in the figure) through the towing hook 3, the grass seeds to be sown and fertilizers are added to the seeder 2, and then the cover plate 9 is opened, and the unbundled grass bale 8 is placed on the storage plate 7, and then the grass bale 8 is guided to the feeding belt 15 through the strip hole. As the material shifting assembly operates, the material shifting assembly can drive the driving roller 5 to rotate, and as the driving roller 5 rotates, the first gear 11 on the driving roller 5 can drive the pressing roller 6 to rotate in the opposite direction through the second gear 12 and the first transmission belt 14 in sequence, and as the pressing roller 6 and the driving roller 5 rotate, the feeding belt 15 and the pressing belt 17 can rotate in the opposite direction. When the grass bale 8 contacts the first convex tooth 16 on the feeding belt 15, the grass bale 8 can cooperate with the feeding belt 15 and the first convex tooth 16. The tractor 10 is used to move the grass bale 8 toward the pressing belt 17 under the action of the feeding belt 15. When the grass bale 8 contacts the pressing belt 17 under the drive of the feeding belt 15, the grass bale 8 can move toward the front side of the shell body 1 under the clamping action of the feeding belt 15 and the pressing belt 17. In this process, the grass bale 8 can be compacted by the feeding belt 15 and the pressing belt 17, and the material shifting assembly can also shift the grass bale 8 forward, so that the grass bale 8 entering between the pressing belt 17 and the feeding belt 15 can become more dense, and then when the grass bale 8 contacts the ground under the drive of the feeding belt 15, the grass bale 8 can maintain a relatively continuous state, and then the grass bale 8 laid on the ground can be pressed into the sand by the grass pressing assembly to form a relatively continuous grass grid as the tractor drives the shell body 1 forward, thereby improving the fixing effect of the grass grid on the sand; When the grass bale 8 is pressed into the sand, the seeder 2 located at the rear side of the housing 1 can perform grass seed sowing and fertilization operations in the grass grid area formed on the ground, thereby achieving the restoration of grassland vegetation.

[0020] like Figure 3 and Figure 4As shown, the material-diverting assembly includes a driving shaft 19, one end of which is rotatably connected to an inner wall of one side of the shell 1, and the other end of the driving shaft 19 is vertically transmitted and penetrates the other side of the plug-in shell 1, and the end of the driving shaft 19 located outside the shell 1 is transmission-connected to a driving motor 20, and a second transmission belt 21 is connected between the end of the driving shaft 19 close to the driving motor 20 and the end of the front driving roller 5 close to the driving motor 20, two driving disks 22 are fixedly sleeved on the driving shaft 19, and the axis of the driving disk 22 does not coincide with the axis of the driving shaft 19, and a swing arm 23 is slidably installed at the edge of the driving disk 22, and a pull rod 24 is hinged at the bottom end of the swing arm 23, and the two pull rods 24 are slidably sleeved with the same A fixed rod 25, both ends of which are horizontally provided with slide rails 26, the two slide rails 26 are respectively fixedly connected to the inner walls of the shell 1 on both sides, and the two ends of the fixed rod 25 are respectively slidably installed in the two slide rails 26, a connecting rod 27 is fixedly connected between the bottom ends of the two pull rods 24, two groups of plug rods 28 are symmetrically arranged at the bottom of the connecting rod 27, and the number of each group of plug rods 28 is multiple, the two groups of plug rods 28 are respectively located at the top of the two groups of feeding components, and the multiple plug rods 28 in each group are plugged one by one between two adjacent feeding belts 15, the bottom end of the plug rod 28 can be higher than the top of the feeding belt 15, and when the plug rod 28 moves forward to the front side, it can just be close to the pressure roller 6 located at the rear side; By providing a material-shifting assembly, when the straw bale 8 moves forward driven by the feeding belt 15 and the pressing belt 17, as the driving motor 20 drives the driving shaft 19 to rotate, the two driving discs 22 can be driven by the driving shaft 19 to rotate eccentrically. During this process, the swing arm 23 can move along the edge of the driving disc 22, and the distance between the top end of the swing arm 23 and the driving shaft 19 is also periodically changed, so that the pull rod 24 can reciprocate in the vertical direction. At the same time, as the driving disc 22 rotates eccentrically, when the axis of the driving disc 22 moves forward, the driving disc 22 can drive the fixed rod 25 to move forward along the slide rail 26 through the pull rod 24, and when the axis of the driving disc 22 moves backward, the driving disc 22 can drive the fixed rod 25 to move backward along the slide rail 26 through the pull rod 24, thereby cooperating with the swing arm 23 to pull the pull rod 24 up and down. The connecting rod 27 drives the insertion rod 28 to move forward and upward at the same time, and drives the insertion rod 28 downward when the connecting rod 27 moves backward. Therefore, when the insertion rod 28 is inserted downward into the grass bale 8, as the swing arm 23 swings forward, the insertion rod 28 can move upward and also push the grass bale 8 in front of it to move further forward, so that the grass bale 8 can be squeezed forward more densely, thereby avoiding the situation where the subsequent grass grid is laid discontinuously due to the grass bale 8 being too loose. Subsequently, the grass bale 8 squeezed together can move forward under the clamping action of the feeding belt 15 and the pressing belt 17 and finally be laid on the ground under the action of gravity. Subsequently, the closely arranged grass bales 8 can be pressed into the sand under the action of the grass pressing assembly, thereby ensuring the laying quality of the grass grid, and then ensuring the fixing effect of the grass grid on the sand, and improving the subsequent sowing effect of grass seeds.

[0021] like Figures 2 to 6As shown, the grass pressing assembly includes two vertically arranged grass pressing discs 29, the two grass pressing discs 29 are respectively located in the middle position of the rear sides of the two groups of feeding components, and the grass pressing discs 29 are parallel to the side surfaces of the shell 1, a fixing plate 30 is rotatably connected between the center of the circles on both sides of the grass pressing disc 29, a sleeve plate 31 is slidably sleeved on the top of the fixing plate 30, and the sleeve plate 31 is vertically fixedly connected to the top inner wall of the shell 1, and the upper half of the fixing plate 30 is penetrated with a through hole along its side direction, and a pressing plate 32 is horizontally inserted between the through holes of the fixing plate 30, and a strip-shaped limiting hole is penetrated between the front and rear sides of the pressing plate 32, and two limiting rods 33 are penetrated and inserted in the limiting hole, and the two ends of the two limiting rods 33 are respectively connected to the two fixed The inner walls of the front and rear sides of the through hole of the fixed plate 30 are vertically fixedly connected, and an electric push rod 34 is vertically fixedly connected to the middle position of the top of the pressure plate 32. Telescopic rods 35 are symmetrically hinged between the positions near the bottom on both sides of the electric push rods 34 and the top of the pressure plate 32. A return spring 36 is sleeved on the telescopic rod 35, and the two ends of the return spring 36 are respectively fixedly connected to the positions near the two ends of the telescopic rod 35. The seeder 2 includes a fertilizer box 202, a plurality of seed boxes 201 arranged side by side, and a plurality of support wheels 203. The fertilizer box 202 is located at the front side of the plurality of seed boxes 201, and the plurality of support wheels 203 are distributed one by one at the rear side of the plurality of seed boxes 201, and the distribution width of the plurality of seed boxes 201 is located between the two grass pressing discs 29; In the process of pressing the grass bale 8 laid on the ground into the sand, due to the uneven ground, the two grass pressing discs 29 cannot maintain good contact with the ground at the same time. At this time, a grass pressing assembly is provided. Before pressing the grass bale 8 into the sand, the length of the electric push rod 34 is adjusted according to the depth of pressing. As the electric push rod 34 gradually extends, the two grass pressing discs 29 can move downward under the pressure of the electric push rod 34 on the pressure plate 32 until the grass pressing disc 29 is inserted into the sand. When the depth of the grass pressing disc 29 inserted into the sand reaches a predetermined value, the electric push rod 34 stops extending. Subsequently, as the tractor pulls the shell 1 forward, the grass pressing disc 29 can move forward with the shell 1. In this process When there is a difference in the ground height between the contact positions of the two grass pressing discs 29, the grass pressing disc 29 relative to the higher ground position can drive the corresponding end of the pressing plate 32 to deflect upward under the pushing of the ground. In this process, the telescopic rod 35 and the return spring 36 on the upwardly deflected side can be gradually compressed, while the other telescopic rod 35 and the return spring 36 can be gradually stretched. As the grass pressing disc 29 at the higher ground position is pushed upward, the grass pressing disc 29 relative to the lower ground position can gradually move downward under the prying of the pressing plate 32, so as to better press the grass bale 8 into the sand, thereby avoiding the grass pressing disc 29 relative to the lower ground position from being unable to press the grass bale 8 into the sand well due to uneven land. During the deflection of the pressing plate 32, the limiting rods 33 on the two fixing plates 30 can slide adaptively along the limiting holes on the pressing plate 32, and the two fixing plates 30 can also enter or move out of the corresponding fixing plates 30, thereby achieving the pressing operation of the straw bale 8 laid on the uneven ground while ensuring that the horizontal spacing between the two straw pressing discs 29 remains unchanged; As the grass bale 8 is pressed into the sand, the fertilizer box 202 can spread the fertilizer into the area where the grass grid is located, and the seeds loaded into the seed box 201 can be evenly sown in the area where the fertilizer is scattered, thereby ensuring the effective survival of the grass seeds and improving the restoration effect of the grassland vegetation.

[0022] like Figure 7 As shown, a material guide plate 37 is fixedly connected to the side of the material storage plate 7 close to the pressure roller 6, the front side of the material guide plate 37 is close to the top of the feeding belt 15, and the rear side of the material guide plate 37 is flush with the bottom hole wall of the strip hole; By providing the guide plate 37, when the straw bale 8 enters between the pressing assembly and the feeding assembly through the strip hole, the guide plate 37 can support and guide the portion of the straw bale 8 extending out of the storage plate 7, so that the straw bale 8 can enter between the pressing assembly and the feeding assembly more smoothly.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
