Description

Technical Field

[0001] The present invention belongs to the technical field of mine reclamation, and in particular relates to land reclamation equipment for green mines and a control method thereof. Background Art

[0002] Mine reclamation refers to the planned remediation of land damaged by excavation, subsidence, and occupation during mine construction and production, restoring it to a usable state. The disruption of local ecological balance during mining is the primary cause of environmental problems in mines. Mine reclamation is currently the primary approach to addressing both the mine environment and the development of the mining economy. Land reclamation in mining areas can be categorized by its intended purpose: agricultural reclamation, forestry reclamation, fishery reclamation, nature conservation reclamation, water resource reclamation, and industrial reclamation. Agricultural and forestry reclamation are the most common. In my country, due to limited arable land, the core of reclamation is the restoration of arable land. From the perspective of land reclamation technology, it is generally divided into two types: reclamation technology with covering and reclamation technology without covering. The non-covering technology refers to the surface soil of mine spoil dumps, tailings fields and even well-weathered quarries, which are similar to cultivated soil and can be planted without surface covering. If the surface soil is significantly different from the cultivated soil, such as too high acidity or alkalinity, low clay content, too low or too high content of certain chemical substances, low soil fertility, etc., soil improvement technology, including the addition of organic fertilizers, soil loosening and ventilation, etc., can be used to improve soil quality.

[0003] However, in the existing mine land reclamation process, soil loosening and aeration and the addition of organic matter are usually carried out separately, which affects the deep and efficient utilization of organic fertilizers and also affects the quality of mine land reclamation.

[0004] Based on this, a land reclamation equipment and a control method thereof for green mines are proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a land reclamation equipment for green mines and a control method thereof in view of the deficiencies of the above-mentioned prior art, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] In a first aspect, a land reclamation device for a green mine comprises a mobile base and a reclamation drum mounted within the mobile base;

[0008] A driving cylinder is rotatably connected in the reclamation cylinder, and the driving cylinder is driven by a driving motor installed at the top of the reclamation cylinder. A fertilizer box is also installed at the top of the reclamation cylinder, and the bottom end of the fertilizer box is connected to the inner cavity of the driving cylinder;

[0009] A reclamation auger is also sleeved on the outside of the driving cylinder, a reclamation spiral is provided on the outside of the reclamation auger, and a fertilizer outlet is provided at the bottom of the reclamation auger. The fertilizer in the fertilizer box can be delivered to the deep soil of the mine through the fertilizer outlet of the reclamation auger.

[0010] As a further explanation of the present invention, a mixing cavity is provided at the top of the driving cylinder, the fertilizer box is divided into at least three fertilizer cavities by a partition, and a discharge control valve plate is provided at the bottom of the fertilizer box. The number of openings of the discharge control valve plate is the same as the number of fertilizer cavities, and the fertilizer in the fertilizer box is delivered to the mixing cavity through the discharge control valve plate.

[0011] As a further illustration of the present invention, an intermediate control valve is installed at the bottom end of the mixing cavity in the driving cylinder, and the fertilizer mixed in the mixing cavity is delivered to the inner bottom cavity of the driving cylinder through the intermediate control valve.

[0012] As a further explanation of the present invention, two limit plates are symmetrically provided on the outer side of the middle and lower sections of the driving cylinder, and a stop block is fixed at the bottom end of the reclamation auger cylinder, and the stop block is connected in the limit plate by sliding up and down.

[0013] As a further explanation of the present invention, an intermediate cylinder is fixed in the reclamation auger cylinder, and an intermediate opening is opened in the middle and lower section of the driving cylinder. The intermediate cylinder is sleeved in the intermediate opening, and a fertilizer feeding cavity is formed between the intermediate cylinder and the inner bottom cavity of the driving cylinder.

[0014] As a further explanation of the present invention, a top plate is fixed on the top of the reclamation cylinder, a middle groove is opened in the middle of the top plate, and an annular plate is fixed on the top of the driving cylinder, and the annular plate is rotatably connected in the middle groove.

[0015] As a further explanation of the present invention, a pulley is installed on the outer side of the driving cylinder near the top, the driving motor is fixed on the top plate of the reclamation cylinder, the bottom end of the output shaft of the driving motor extends to the interior of the reclamation cylinder, and a driving wheel is fixed at the bottom end of the output shaft of the driving motor, and the driving wheel and the pulley are driven and connected by a belt ring.

[0016] As a further explanation of the present invention, a transverse frame is also installed in the reclamation cylinder, an intermediate plate is fixed in the middle of the transverse frame, the driving cylinder is sleeved in the intermediate plate, and two hydraulic cylinders are symmetrically fixed on the bottom side of the intermediate plate. An L-shaped plate is installed at the bottom end of the telescopic shaft of the hydraulic cylinder, and the L-shaped plate is clamped at the top of the reclamation auger cylinder.

[0017] As a further explanation of the present invention, an annular clamping plate is fixed to the top of the reclamation auger barrel, and the L-shaped plate is installed at the bottom end of the telescopic shaft of the hydraulic cylinder through a steering motor. The direction of the L-shaped plate can be adjusted by the steering motor to complete the clamping connection between the L-shaped plate and the clamping plate.

[0018] In a second aspect, a control method for land reclamation equipment for a green mine comprises the following steps:

[0019] First, the mobile base drives the reclamation drum to move to the surface of the mine soil to be reclaimed and fertilized. Then, different types of fertilizers are placed in different fertilizer chambers in the fertilizer box. The discharge control valve plate is used to control the single fertilizer application amount in the fertilizer box, and different fertilizers are delivered to the mixing chamber.

[0020] Then the driving motor is started, and the driving motor drives the pulley to rotate through the driving wheel belt ring. When the pulley rotates, it can drive the driving drum to rotate synchronously. When the driving drum rotates, it can synchronously drive the reclamation auger to rotate under the action of the block and the limit plate. When the reclamation auger rotates, the outer reclamation spiral drill penetrates into the deep layer of the mine soil. At the same time, due to the rotation of the driving drum, the fertilizer in the mixing chamber can be mixed synchronously.

[0021] After the reclamation auger barrel drills into the mine soil to a preset depth, the drive motor stops rotating and the intermediate control valve is controlled to deliver the mixed fertilizer in the mixing chamber to the inner bottom chamber of the drive barrel. Specifically, the mixed fertilizer is delivered to the fertilizer feeding chamber formed between the intermediate barrel and the drive barrel.

[0022] Then open the fertilizer outlet at the bottom of the reclamation auger barrel, and control the drive motor to rotate in the opposite direction at the same time. When the drive motor rotates in the opposite direction, it can drive the reclamation auger barrel to rotate in the opposite direction through the drive barrel. When the reclamation auger barrel rotates in the opposite direction, it drives the reclamation auger barrel to move out from the deeper soil layer, and can complete the loosening operation synchronously. At the same time, when moving out, the mixed fertilizer in the fertilizer feeding chamber can be applied into the longitudinal soil layer through the fertilizer outlet, so that the longitudinal deep fertilization operation can be carried out while loosening the soil, completing the reclamation operation of the mine land.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. The present invention is characterized by installing a reclamation cylinder in a mobile base, a driving cylinder rotatably connected in the reclamation cylinder, and a driving cylinder driven by a driving motor installed on the top of the reclamation cylinder. A fertilizer box is also installed on the top of the reclamation cylinder. The fertilizer box is divided into at least three fertilizer cavities by a partition. Different types of organic fertilizers are placed in each fertilizer cavity, so that the combination of organic fertilizers can be facilitated and the use effect of the fertilizers is improved. A discharge control valve plate is provided at the bottom of the fertilizer box. The number of openings of the discharge control valve plate is set. The number is the same as the fertilizer cavities, so different types of organic fertilizers can be classified and sent to the mixing cavity through the discharge control valve plate. An intermediate control valve is installed at the bottom of the mixing cavity in the driving cylinder. The fertilizer mixed in the mixing cavity is sent to the fertilizer feeding cavity in the driving cylinder through the intermediate control valve. A fertilizer outlet is provided at the bottom of the reclamation auger cylinder. The fertilizer in the fertilizer box can be sent to the deep soil of the mine through the fertilizer outlet of the reclamation auger cylinder, which is convenient for adding and using organic fertilizers in the vertical soil layer.

[0025] 2. The present invention has a reclamation auger barrel sleeved on the outside of the driving barrel, and a reclamation spiral is provided on the outside of the reclamation auger barrel. The reclamation spiral can loosen the soil during its rotation. Two limit plates are symmetrically provided on the outside of the middle and lower sections of the driving barrel. A stopper is fixed to the bottom end of the reclamation auger barrel, and the stopper slides up and down and is connected in the limit plate. When the driving barrel rotates, the stopper can be driven to rotate by the limit plate in the driving barrel, thereby driving the reclamation auger barrel to rotate synchronously. Since the stopper slides up and down and is connected in the limit plate, the depth of the reclamation auger barrel into the soil can be independently adjusted during its selection and use, which is convenient for the matching power transmission operation.

[0026] 3. The reclamation cylinder of the present invention is also equipped with a transverse frame, an intermediate plate is fixed in the middle of the transverse frame, the driving cylinder is sleeved in the intermediate plate, the intermediate plate can ensure the stability of the driving cylinder during rotation, and two hydraulic cylinders are symmetrically fixed on the bottom side of the intermediate plate. The bottom end of the telescopic shaft of the hydraulic cylinder is equipped with an L-shaped plate, which is clamped on the top of the reclamation auger cylinder. The top of the reclamation auger cylinder is fixed with an annular clamping plate. The L-shaped plate is installed on the bottom end of the telescopic shaft of the hydraulic cylinder through a steering motor. The direction of the L-shaped plate can be adjusted by the steering motor to complete the L-shaped plate. The clamping connection between the clamping plate and the clamping plate is used before mine land reclamation, that is, the sleeve length between the reclamation auger barrel and the driving cylinder is the maximum. The steering motor is used to adjust the direction of the L-shaped plate to make the clamping connection between the L-shaped plate and the clamping plate, so that the reclamation auger barrel and the driving cylinder are stably connected. When mine land reclamation is carried out, after the mobile base is moved to the appropriate position, the steering motor is used to adjust the direction of the L-shaped plate to disengage the L-shaped plate from the clamping plate, so that the bottom end of the reclamation auger barrel naturally contacts the ground surface, which is convenient for selective loosening operations.

[0027] 4. When the present invention is used, the mobile base is first used to drive the reclamation drum to move to the surface of the mine soil to be reclaimed and fertilized. Then, different types of fertilizers are respectively put into different fertilizer cavities in the fertilizer box, and the single fertilization amount of fertilizers in the fertilizer box is controlled by the discharge control valve plate, and different fertilizers are sent to the mixing cavity; then the driving motor is started, and the driving motor drives the pulley to rotate through the driving wheel belt ring. When the pulley rotates, it can drive the driving drum to rotate synchronously. When the driving drum rotates, it can synchronously drive the reclamation auger drum to rotate under the action of the block and the limit plate. When the reclamation auger drum rotates, the outer reclamation spiral drills into the deep layer of the mine soil. At the same time, the rotation of the driving drum can synchronously drive the mixing of the fertilizers in the mixing cavity; the reclamation auger drum drills into the mine to be reclaimed. After reaching a preset depth in the mountain soil, the rotation of the driving motor is stopped, and at the same time, the intermediate control valve is controlled to send the mixed fertilizer in the mixing chamber to the inner bottom chamber of the driving cylinder, specifically, the mixed fertilizer is sent to the space between the intermediate cylinder and the driving cylinder to form a fertilizer feeding chamber; then the fertilizer outlet at the bottom end of the reclamation auger barrel is opened, and at the same time, the driving motor is controlled to rotate in the opposite direction. When the driving motor rotates in the opposite direction, it can drive the reclamation auger barrel to rotate in the opposite direction through the driving cylinder, and when the reclamation auger barrel rotates in the opposite direction, it drives the reclamation auger barrel to move out from the deeper soil layer, and can complete the loosening operation synchronously. At the same time, when moving out, the mixed fertilizer in the fertilizer feeding chamber can be applied into the longitudinal soil layer through the fertilizer outlet, so that the longitudinal deep fertilization operation can be carried out while loosening the soil, completing the reclamation operation of the mining land efficiently and conveniently.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figure 1-7 As shown, the present invention provides a technical solution: a land reclamation equipment for green mines, comprising a mobile base 1 and a reclamation drum 2 installed in the mobile base 1, and a roller or crawler self-driving device is provided at the bottom of the mobile base 1. The reclamation drum 2 can be moved to the surface of the mine land to be reclaimed and fertilized through the mobile base 1, thereby improving the convenience of equipment use.

[0039] A driving cylinder 3 is rotatably connected inside the reclamation cylinder 2. The driving cylinder 3 is driven by a driving motor 6 installed at the top of the reclamation cylinder 2. A top plate 21 is fixed to the top of the reclamation cylinder 2. A middle groove is opened in the middle of the top plate 21. An annular plate 32 is fixed to the top of the driving cylinder 3. The annular plate 32 is rotatably connected in the middle groove.

[0040] A pulley 33 is installed on the outside of the driving cylinder 3 near the top, the driving motor 6 is fixed on the top plate 21 of the reclamation cylinder 2, the bottom end of the output shaft of the driving motor 6 extends to the interior of the reclamation cylinder 2, and a driving wheel 61 is fixed at the bottom end of the output shaft of the driving motor 6, and the driving wheel 61 and the pulley 33 are driven and connected by a belt ring.

[0041] A fertilizer box 4 is also installed at the top of the reclamation cylinder 2. A fertilizer cover 41 is provided at the top opening of the fertilizer box 4. The bottom end of the fertilizer box 4 is connected to the inner cavity of the driving cylinder 3.

[0042] Specifically, a mixing cavity 31 is provided at the top of the driving cylinder 3, and the fertilizer box 4 is divided into at least three fertilizer cavities by a partition 42. Different types of organic fertilizers are placed in each of the fertilizer cavities, which facilitates the combination of organic fertilizers and improves the use effect of the fertilizers.

[0043] A discharge control valve plate 43 is provided at the bottom of the fertilizer box 4. The number of openings of the discharge control valve plate 43 is the same as the number of fertilizer cavities, so that different types of organic fertilizers can be classified and delivered to the mixing cavity 31 through the discharge control valve plate 43.

[0044] An intermediate control valve 34 is installed at the bottom end of the mixing cavity 31 in the driving cylinder 3 , and the fertilizer mixed in the mixing cavity 31 is delivered to the inner bottom cavity of the driving cylinder 3 through the intermediate control valve 34 .

[0045] The outer side of the driving cylinder 3 is also sleeved with a reclamation auger cylinder 5. Two limit plates 35 are symmetrically provided on the outer side of the middle and lower sections of the driving cylinder 3. A stopper 51 is fixed to the bottom end of the inner side of the reclamation auger cylinder 5. The stopper 51 is slidably connected between the two limit plates 35. When the driving cylinder 3 rotates, the limit plate 35 in the driving cylinder 3 can drive the baffle 51 to rotate, thereby driving the reclamation auger cylinder 5 to rotate synchronously.

[0046] Since the stopper 51 is connected to the limit plate 35 by sliding up and down, the depth of the land penetration of the reclamation auger 5 can be adjusted automatically during the use process, which is convenient for the supporting power transmission operation.

[0047] A reclamation screw is provided on the outside of the reclamation auger barrel 5, and the soil can be loosened during the rotation of the reclamation screw.

[0048] An intermediate cylinder 52 is also fixed in the reclamation auger cylinder 5, and an intermediate opening 36 is also opened in the middle and lower section of the driving cylinder 3. The intermediate cylinder 52 is sleeved in the intermediate opening 36, and a fertilizer feeding cavity is formed between the intermediate cylinder 52 and the inner bottom cavity of the driving cylinder 3. A fertilizer outlet 53 is provided at the bottom end of the reclamation auger cylinder 5, and the fertilizer in the fertilizer box 4 can be delivered to the deep soil of the mine through the fertilizer outlet 53 of the reclamation auger cylinder 5.

[0049] A transverse frame 7 is further installed in the reclamation cylinder 2 , and an intermediate plate 71 is fixed in the middle of the transverse frame 7 . The driving cylinder 3 is sleeved in the intermediate plate 71 . The intermediate plate 71 can ensure the stability of the driving cylinder 3 during rotation.

[0050] Two hydraulic cylinders 72 are symmetrically fixed to the bottom side of the middle plate 71. An L-shaped plate 73 is installed at the bottom end of the telescopic shaft of the hydraulic cylinder 72. The L-shaped plate 73 is clamped at the top of the reclamation auger barrel 5. An annular clamping plate 37 is fixed to the top of the reclamation auger barrel 5. The L-shaped plate 73 is installed at the bottom end of the telescopic shaft of the hydraulic cylinder 72 through a steering motor. The direction of the L-shaped plate 73 can be adjusted by the steering motor to complete the clamping connection between the L-shaped plate 73 and the clamping plate 37.

[0051] Specifically, before the mine land is reclaimed, the direction of the L-shaped plate 73 is adjusted by using the steering motor so that the L-shaped plate 73 is connected to the clamping plate 37, so that the reclamation auger barrel 5 and the driving barrel 3 are stably connected, and the hydraulic cylinder 72 is used to pull up so that the reclamation auger barrel 5 is at the highest point. When the mine land is reclaimed, after the mobile base 1 is moved to the appropriate position, the direction of the L-shaped plate 73 is adjusted by using the steering motor so that the L-shaped plate 73 is disengaged from the clamping plate 37, so that the bottom end of the reclamation auger barrel 5 naturally contacts the ground surface, which is convenient for selective loosening operations.

[0052] The above-mentioned control method for land reclamation equipment for green mines includes the following steps:

[0053] First, the mobile base 1 drives the reclamation drum 2 to move to the surface of the mine soil to be reclaimed and fertilized. Then, different types of fertilizers are placed in different fertilizer chambers in the fertilizer box 4. The discharge control valve plate 43 is used to control the single fertilizer application amount in the fertilizer box 4, and the different fertilizers are delivered to the mixing chamber 31.

[0054] Then the drive motor 6 is started, and the drive motor 6 drives the pulley 33 to rotate through the belt loop of the drive wheel 61. When the pulley 33 rotates, it can drive the drive cylinder 3 to rotate synchronously. When the drive cylinder 3 rotates, it can synchronously drive the reclamation auger 5 to rotate under the action of the block 51 and the limit plate 35. When the reclamation auger 5 rotates, the outer reclamation auger drills into the deep layer of the mine soil. At the same time, due to the rotation of the drive cylinder 3, the fertilizer in the mixing chamber 31 can be mixed synchronously.

[0055] After the reclamation auger 5 has drilled into the mine soil to a preset depth, the drive motor 6 is stopped, and the intermediate control valve 34 is controlled to deliver the mixed fertilizer in the mixing chamber 31 to the inner bottom chamber of the drive cylinder 3. Specifically, the mixed fertilizer is delivered to the fertilizer feeding chamber formed between the intermediate cylinder 52 and the drive cylinder 3.

[0056] Then, the fertilizer outlet 53 at the bottom of the reclamation auger barrel 5 is opened, and the drive motor 6 is controlled to rotate in the reverse direction. When the drive motor 6 rotates in the reverse direction, it can drive the reclamation auger barrel 5 to rotate in the reverse direction through the drive barrel 3. During the reverse rotation of the reclamation auger barrel 5, the outer reclamation spiral rotates in the reverse direction, and the resistance generated by the contact with the deep soil of the mine land forms a reverse thrust, which causes the reclamation auger barrel 5 to rise under the action of the reverse thrust.

[0057] When the deep soil of the mine land becomes loose, the relative force between the soil and the reclamation spiral outside the reclamation auger 5 is insufficient, and the reclamation auger 5 stops rising and rotating in place, the soil loosening operation is completed. At the same time, when it is moved out, the mixed fertilizer in the fertilizer feeding chamber can be applied to the longitudinal soil layer through the fertilizer outlet 53, so that the longitudinal deep fertilization operation can be carried out while loosening the soil, completing the reclamation operation of the mine land;

[0058] Then, the telescopic shaft of the hydraulic cylinder 72 is controlled to descend again so that the height of the L-shaped plate 73 is below the clamping plate 37. After the direction of the L-shaped plate 73 is adjusted by the steering motor until the L-shaped plate 73 and the clamping plate 37 are clamped and connected, the telescopic shaft of the hydraulic cylinder 72 is used to rise to reset the reclamation auger barrel 5, that is, the reclamation auger barrel 5 is at the highest point. The position of the mobile base 1 is adjusted again, and the reclamation barrel 2 is moved to the next operating point for cyclic operation, which is efficient and convenient.
