Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration construction, and in particular to a vegetation reconstruction construction device and method based on ecological restoration of open-pit coal mines. Background Art

[0002] During open-pit coal mining, large-scale stripping of surface rock and coal sorting operations result in a large amount of coal gangue mixed in the soil of the mining area. Coal gangue is hard and has poor water and fertilizer retention capacity. Some of it contains sulfides or heavy metals, which directly hinder the development of vegetation roots and may cause soil acidification or pollution. Therefore, it needs to be removed from the soil during ecological restoration (soil preparation stage).

[0003] During vegetation reconstruction, the soil in the mining area must be sorted out first. The core process is: scooping the surface mixed soil → screening to remove the gangue → crushing the soil and discharging it (usually a certain amount of exogenous soil is also required, generally organic-rich loess or improved loam, to make up for the lack of nutrients and optimize the soil structure). The above process has significant defects: (1) The shoveled soil is not pre-crushed, and the agglomerated soil will also be screened out, making the separation effect of the gangue and the soil unsatisfactory, resulting in the loss of usable soil; (2) The surface of the gangue is adhered to the usable soil, which is discarded due to the lack of effective stripping methods. The gangue removed by screening is usually used as a filling base for ecological restoration (such as windbreak wall masonry and slope protection gabion filling). The residual soil on its surface will reduce the mechanical bite force between the aggregates, affecting the structural stability, and requiring an additional soil removal process.

[0004] Therefore, the present invention proposes a vegetation reconstruction construction device and method based on open-pit coal mine ecological restoration to solve the above problems. Summary of the Invention

[0026] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] See also Figure 1 and Figure 2, a vegetation reconstruction construction device based on open-pit coal mine ecological restoration, including a carrier 1 and a shovel assembly 2 for shoveling soil provided on the carrier 1 (the shovel assembly 2 includes a mounting bracket connected to the carrier 1, a rotating drum, a plurality of buckets circumferentially arranged on the rotating drum, and a power system for driving the rotating drum to rotate. It is a prior art, so the specific components of the shovel assembly 2 and the connection relationship between the components are not described here). The carrier 1 is also provided with a processing box 4 and a conveying assembly 3 for conveying the shoveled soil to the processing box 4. The processing box 4 is alternately provided with a plurality of receiving platforms 5 with hollow interiors for receiving soil from top to bottom. The upper side of the receiving platform 5 is inclined, and the upper side of the receiving platform 5 is evenly distributed with lower soil holes 10. The construction device also includes a processing assembly 6 for crushing the soil on the receiving platform 5 and stripping off the soil adhered to the coal gangue.

[0028] It should be noted that the construction device as a whole is towed and pulled by a traction device (such as a tractor) to work, and a plurality of groups of rollers are symmetrically provided at the bottom of the platform 1.

[0029] The construction device is connected to the traction device, which drags the construction device forward to carry out soil preparation work. The soil is scooped up by the shoveling component 2 and transported to the processing box 4 through the conveying component 3. The soil in the processing box 4 falls on the receiving platform 5 from top to bottom and rolls along the receiving platform 5. In this process, the soil on the receiving platform 5 is crushed and the soil adhered to the coal gangue is stripped off by the processing component 6. The crushed soil falls into the receiving platform 5 through the lower soil hole 10 and is discharged. After the soil is stripped, the coal gangue finally falls to the bottom of the processing box 4 for collection (the bottom of the processing box 4 is provided with a material taking port for taking out the coal gangue). One processing process (excluding shoveling and soil conveying processes) achieves the triple purposes of soil crushing, stripping the soil adhered to the coal gangue and removing the coal gangue, which greatly improves the soil preparation efficiency and quality in the open-pit coal mine area and lays a solid foundation for subsequent vegetation planting.

[0030] Furthermore, the lower side of the receiving platform 5 is also inclined, and soil discharge channels 7 with open lower ends are provided on both sides of the processing box 4. The interior of the receiving platform 5 is connected with the corresponding soil discharge channels 7. The soil falling into the receiving platform 5 rolls along the lower side of the receiving platform 5 to the corresponding soil discharge channel 7, and is discharged from the lower end of the soil discharge channel 7 and falls into the shoveled area.

[0031] See also Figures 1 to 4In one embodiment of the present invention, the processing assembly 6 includes a soil-breaking component corresponding to the receiving platform 5 one by one. The soil-breaking component includes a mounting plate 601 provided above the receiving platform 5 and capable of cyclically moving up and down. The mounting plate 601 is slidably penetrated by a soil-breaking rod 602 in a matrix manner. The soil-breaking rod 602 is provided with a limiter 607 on the rod section above the mounting plate 601, and a plurality of first elastic members 608 are provided between the soil-breaking rod 602 and the mounting plate 601 (the first elastic members 608 are elastic ropes, springs, etc. in the prior art); The vertical distances between the lower end of each of the earth-breaking rods 602 and the upper side of the corresponding receiving platform 5 are the same to adapt to the change in the slope of the upper side of the receiving platform 5.

[0032] In this embodiment, the mounting plate 601 is moved up and down cyclically to drive the soil-breaking rod 602 to move accordingly. The soil-breaking rod 602 will penetrate into the soil during its downward movement to crush the soil. For coal gangue, the soil-breaking rod 602 will also penetrate into the soil adhered to the coal gangue to crush it, thereby achieving the effect of peeling off the soil adhered to the coal gangue, until the lower end of the soil-breaking rod 602 contacts the coal gangue body. The soil-breaking rod 602 in contact with the coal gangue body slides upward relative to the mounting plate 601 under the pressure, thereby forming a three-dimensional shape with the coal gangue. Correspondingly, when the mounting plate 601 moves upward, the breaking rod 602 in contact with the gangue body is reset under the action of the first elastic member 608, and the gangue is no longer pressed by the breaking rod 602 and resumes rolling, thereby continuously adjusting the contact portion with the breaking rod 602 in the subsequent process, thereby achieving the technical effect of fully stripping off the soil adhered to the gangue; it should be noted that under normal circumstances, the strength of several first elastic members 608 on the same breaking rod 602 meets the requirement: it can support the corresponding breaking rod 602 to penetrate deep into the soil without generating substantial sliding displacement.

[0033] Furthermore, in this embodiment, the upper side of the receiving platform 5 is in the shape of multiple steps extending downward from high to low, and there is a vertical drop between the two adjacent side sections on the upper side of the receiving platform 5. The essence of this embodiment of crushing the soil by the soil-breaking rod 602 is that the agglomerated soil becomes loose continuously under the cyclic impact of the soil-breaking rod 602 and the soil's own rolling adjustment direction, so that the agglomerated soil is continuously separated to achieve the crushing effect. The stepped shape of the upper side of the receiving platform 5 makes the agglomerated soil and coal gangue roll downward. Each time they fall down a "step", they will be subjected to a certain instantaneous impact force (including falling from the upper receiving platform 5 to the lower receiving platform 5). This instantaneous impact force can promote the gradually loosened soil (including the soil adhered to the coal gangue) to achieve the crushing effect and promote the soil adhered to the coal gangue to break and fall off, thereby improving the soil stripping effect.

[0034] Furthermore, in this embodiment, in order to prevent the soil from splashing onto the mounting plate 601 and being unable to fall when the soil falls from the upper receiving platform 5 to the lower receiving platform 5, except for the soil-breaking component located at the top, a curtain 12 for blocking the soil is provided between the mounting plate 601 and the receiving platform 5 located above it in each of the other soil-breaking components. Preferably, the curtain 12 is a foldable rubber curtain.

[0035] Based on the previous example, please refer to Figure 1 In one embodiment of the present invention, the processing assembly 6 also includes a driving component for realizing the cyclic up and down movement of the mounting plate 601, and the driving component includes a telescopic member 603 provided on the processing box 4 (the telescopic member 603 is an electric telescopic rod, a hydraulic push rod, etc. in the prior art) and a connecting rod 605 provided at the movable end of the telescopic member 603. A connecting rod 604 is provided between the mounting plate 601 and the connecting rod 605. A first passage groove 606 corresponding to the connecting rod 604 is provided on the side wall of the processing box 4, which is used for the connecting rod 604 to move up and down. The reciprocating telescopic movement of the telescopic member 603 drives the mounting plates 601 in all the earth-breaking components to move up and down synchronously.

[0036] See also Figure 1 、 Figures 3 to 6 In one embodiment of the present invention, the construction device further includes a vibration assembly 11 corresponding to the earth-breaking component, for vibrating the earth-breaking component to loosen and break the soil; The vibration assembly 11 includes a collision member 1101 provided on the mounting plate 601, a resistance member 1102 hinged on the collision member 1101, and a suspension rod 1103 hinged in the processing box 4. The lower end of the suspension rod 1103 is provided with a collision ball 1104. The hinge between the suspension rod 1103 and the processing box 4 is provided with a first torsion spring. Under the action of the first torsion spring, the suspension rod 1103 always has a tendency to deflect toward the collision member 1101. The resistance member 1102 is provided with a A second passage slot 1107, which is open at one end away from the struck member 1101. A second torsion spring is provided at the hinge between the resisting member 1102 and the struck member 1101. In a natural state, the resisting member 1102 is in a horizontal state under the action of the second torsion spring. An upper limit boss 1105 and a lower limit boss 1106 are also provided on the struck member 1101 for limiting the upper and lower deflection limit positions of the resisting member 1102. The connecting rod 604 can be laterally extended and retracted a certain distance; The connecting rod 604 includes a first rod body 6041 and a second rod body 6042. The opposite ends of the first rod body 6041 and the second rod body 6042 are respectively provided with a plug-in shaft 6043 with a square radial cross-section and a plug-in groove 6044 adapted to the plug-in shaft 6043. A partial shaft section of the plug-in shaft 6043 is inserted into the plug-in groove 6044. A second elastic member 6045 is provided in the plug-in groove 6044, and the two ends of the second elastic member 6045 are respectively fixedly connected to the plug-in shaft 6043 and the bottom of the plug-in groove 6044. Preferably, the second elastic member 6045 is a spring (whose spring coefficient is greater than that of the first torsion spring).

[0037] In this embodiment, the mounting plate 601 moves up and down, driving the impacted member 1101 to move accordingly. During the downward movement of the mounting plate 601, the resistance member 1102 comes into contact with the impact ball 1104. Under the blocking action of the impact ball 1104, the resistance member 1102 will deflect upward until it contacts the upper limit boss 1105. The resistance member 1102 is inclined. As the mounting plate 601 continues to move downward, the inclined resistance member 1102 will press against the impact ball 1104 to push it, causing the boom 1103 to move away from the impacted member 1101. When the mounting plate 601 moves down into place (that is, the breaking rod 602 is deeply embedded in the soil or against the coal gangue), the impact ball 1104 is disengaged from the resistance member 1102. At this time, the resistance member 1102 is restored to a horizontal state under the action of the second torsion spring. The impact ball 1104 impacts the impacted part 1101 under the action of its own gravity and the first torsion spring. Since the connecting rod 604 can be extended and retracted a certain distance laterally, when the impact ball 1104 impacts the impacted part 1101, the mounting plate 601 can produce an instantaneous lateral movement (micro distance), and the breaking rod 602 produces a corresponding instantaneous movement. The impact force of the instantaneous movement is used to cause the soil to break, thereby improving the efficiency and quality of soil crushing, and also improving the efficiency and quality of stripping the soil adhered to the coal gangue. Similarly, when the mounting plate 601 moves up and returns to its original position (that is, the breaking rod 602 is separated from the soil), the impact ball 1104 will also impact the impacted part 1101, causing the breaking rod 602 to produce an instantaneous movement, and the instantaneous movement is used to cause the soil that may be adhered to the breaking rod 602 to fall off.

[0038] Furthermore, in this embodiment, the ground-breaking rod 602 is made of spring steel material, so that the ground-breaking rod 602 has a certain elasticity. The purpose is to avoid the ground-breaking rod 602 being restricted (such as the lower end of the ground-breaking rod 602 is stuck in the hole on the coal gangue) and the instantaneous lateral movement of the mounting plate 601 causing the ground-breaking rod 602 to be deformed and damaged. The ground-breaking rod 602 can adaptively deform when the lateral force reaches a certain level.

[0039] See also Figure 1In one embodiment of the present invention, a soil drop box 8 into which soil falls is further provided between the shoveling assembly 2 and the conveying assembly 3. The conveying assembly 3 is a screw conveyor, comprising a conveying cylinder, a spiral dragon arranged in the conveying cylinder, and a driving member for driving the spiral dragon to rotate. The inlet end of the conveying cylinder is connected to the soil drop box 8 (the bottom side of the soil drop box 8 is inclined, so that the soil moves toward the inlet end of the conveying cylinder and gathers), and the discharge end is connected to the processing box 4. The conveying cylinder is also provided with a drying assembly 9 for promoting soil drying. The drying assembly 9 can be a plurality of electric heating elements arranged around the conveying cylinder. (such as electric heating tubes, electric heating wires, etc.), or other heating structures, which are not limited in this embodiment. The construction device is suitable for use when the soil is relatively dry, and is adapted to the characteristics of the relatively dry soil in open-pit coal mines (reasons include the surface soil and vegetation being stripped off due to mining activities, destroying the original structure and water holding capacity; mining dust covering the surface, inhibiting rainwater infiltration, etc.), but it does not rule out the possibility that the soil may not be dry enough during actual construction. By setting a drying component 9, the shoveled soil is heated to promote its drying, and then enters the processing box 4 for subsequent processing.

[0040] The present invention also provides a method for revegetation construction based on open-pit coal mine ecological restoration, which uses a device for revegetation construction based on open-pit coal mine ecological restoration according to any one of the above technical solutions, comprising the following steps: S1: Connecting the construction device to a traction device, and having the traction device drag the construction device forward to perform soil preparation work; S2: Soil is scooped up by the shoveling component 2 and transported to the processing box 4 through the conveying component 3. The soil in the processing box 4 falls on the receiving platform 5 from top to bottom and rolls along the receiving platform 5. During this process, the soil on the receiving platform 5 is crushed and the soil adhered to the gangue is stripped off by the processing component 6. The crushed soil falls into the receiving platform 5 through the lower soil hole 10 and is discharged, and the gangue finally falls to the bottom of the processing box 4 after being stripped off by the soil and is collected.

[0041] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
