Description

Technical Field

[0001] The 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 work of systematically renovating the land damaged by excavation, collapse, occupation, etc. during the mine construction and production process to restore it to a usable state. In the process of mining, the destruction of the local ecological balance is the main source of mine environmental problems. Mine reclamation is the main way to solve the mine environment and mine economic development at this stage. Mining land reclamation can be divided into agricultural reclamation, forestry reclamation, fishery reclamation, nature conservation reclamation, water resource reclamation and industrial reclamation according to its use. Among them, agricultural reclamation and forestry reclamation are the most common. In my country, due to the limited area of ​​arable land, the core of reclamation is to restore arable land. From the perspective of land reclamation technology, it is generally divided into two types: reclamation with covering and reclamation without covering. The non-covering technology refers to mine spoil dumps, tailings yards and even well-weathered quarries, where the surface soil is similar to the 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 aeration, and other measures, 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

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; A reclamation auger is sleeved on the outside of the driving cylinder, a reclamation spiral is arranged on the outside of the reclamation auger, and a fertilizer outlet is arranged at the bottom of the reclamation auger, through which the fertilizer in the fertilizer box can be delivered to the deep soil of the mine.

[0007] As a further explanation of the present invention, a mixing chamber is provided at the top end of the driving cylinder, the fertilizer box is divided into at least three fertilizer chambers by a partition, and a discharge control valve plate is provided at the bottom end of the fertilizer box. The number of openings of the discharge control valve plate is the same as the number of fertilizer chambers, and the fertilizer in the fertilizer box is delivered to the mixing chamber through the discharge control valve plate.

[0008] As a further explanation 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 sent to the inner bottom cavity of the driving cylinder through the intermediate control valve.

[0009] As a further explanation of the present invention, two limit plates are symmetrically arranged on the outer side of the middle and lower sections of the driving cylinder, and a stop block is fixed to the bottom end of the reclamation auger cylinder, and the stop block is slidably connected in the limit plate.

[0010] 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.

[0012] 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.

[0013] As a further explanation of the present invention, a transverse frame is also installed in the reclamation barrel, an intermediate plate is fixed in the middle of the transverse frame, the driving barrel 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 barrel.

[0014] 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.

[0015] In a second aspect, a control method for land reclamation equipment for a green mine comprises the following steps: First, the mobile base is used to drive the reclamation cylinder to move to the surface of the mine land to be reclaimed and fertilized. Then, different types of fertilizers are put into different fertilizer chambers in the fertilizer box. The single fertilizer application amount of the fertilizer in the fertilizer box is controlled by the discharge control valve plate, and different fertilizers are sent to the mixing chamber. Then the driving motor is started, and the driving motor drives the pulley to rotate through the driving wheel belt ring. The rotation of the pulley can drive the driving cylinder to rotate synchronously. When the driving cylinder 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 drills into the deep layer of the mine soil. At the same time, the rotation of the driving cylinder can synchronously drive the mixing of the fertilizer in the mixing chamber; After the reclamation auger barrel drills into the mine land to a preset depth, the driving motor stops rotating, and the intermediate control valve is controlled to send the mixed fertilizer in the mixing chamber to the inner bottom chamber of the driving barrel, specifically, the mixed fertilizer is sent to the fertilizer feeding chamber formed between the intermediate barrel and the driving barrel; Then open the fertilizer outlet at the bottom of the reclamation auger barrel, and control the driving motor to rotate in the opposite direction at the same time. 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 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 the soil loosening operation can be completed simultaneously. At the same time, when moving out, the mixed fertilizer in the fertilizer feeding cavity 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, and the reclamation operation of the mine land can be completed.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention has a reclamation cylinder installed in a mobile base, a driving cylinder is rotatably connected in the reclamation cylinder, 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 fertilizer box is divided into at least three fertilizer cavities by a partition, and different types of organic fertilizers are placed in each fertilizer cavity, so that the combination of organic fertilizers can be conveniently used, and the use effect of the fertilizers is improved. A discharge control valve plate is arranged at the bottom of the fertilizer box, and the number of openings of the discharge control valve plate is The number of the organic fertilizers is the same as that of the fertilizer cavities, so that 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, and 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, and 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. 2. The present invention has a reclamation auger barrel sleeved on the outer side of the driving barrel, and a reclamation spiral is arranged on the outer side of the reclamation auger barrel. The reclamation spiral can perform soil loosening operations during its rotation. Two limit plates are symmetrically arranged on the outer side 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 is connected in the limit plate by sliding up and down. When the driving barrel rotates, the stopper can be driven to rotate through the limit plate in the driving barrel, thereby driving the reclamation auger barrel to rotate synchronously. Since the stopper is connected in the limit plate by sliding up and down, the depth of the reclamation auger barrel into the soil can be independently adjusted during the use of the reclamation auger barrel, which is convenient for the matching power transmission operation. 3. A transverse frame is also installed in the reclamation cylinder of the present invention, and 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.

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 L-shaped plate. The clamping connection between the clamping plate and the clamping plate is used before the mine land reclamation is carried out, 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 carrying out mine land reclamation, 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 make the L-shaped plate disengaged 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. 4. When the present invention is used specifically, the mobile base is first used to drive the reclamation drum to move to the surface of the mine land to be reclaimed and fertilized. Then, different types of fertilizers are respectively put into different fertilizer cavities in the fertilizer box, and the single fertilizer application amount of the fertilizer 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. The rotation of the pulley 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 land. 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 to be reclaimed drills into the mine 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 cylinder 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 cylinder to rotate in the opposite direction through the driving cylinder, and when the reclamation auger cylinder rotates in the opposite direction, it drives the reclamation auger cylinder to move out from the deeper soil layer, and the loosening operation can be completed 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, and the reclamation operation of the mining land can be completed efficiently and conveniently.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] A driving cylinder 3 is rotatably connected inside the reclamation cylinder 2, and the driving cylinder 3 is driven by a driving motor 6 installed on the top of the reclamation cylinder 2. A top plate 21 is fixed on the top of the reclamation cylinder 2, and a middle groove is opened in the middle of the top plate 21.

[0022] A pulley 33 is installed on the outer side 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 inside of the reclamation cylinder 2, and a driving wheel 61 is fixed to 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.

[0023] A fertilizer box 4 is also installed at the top of the reclamation cylinder 2, and a fertilizer cover plate 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. Specifically, a mixing chamber 31 is provided at the top of the driving cylinder 3, and the fertilizer box 4 is divided into at least three fertilizer chambers by a partition 42. Different types of organic fertilizers are placed in each fertilizer chamber, thereby facilitating the combination of organic fertilizers and improving the use effect of the fertilizers.

[0024] A discharge control valve plate 43 is disposed 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 .

[0025] 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 .

[0026] A reclamation auger cylinder 5 is also sleeved on the outer side of the driving cylinder 3, and two limit plates 35 are symmetrically arranged 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 reclamation auger cylinder 5, and the stopper 51 is slidably connected between the two limit plates 35. When the driving cylinder 3 rotates, the stopper 51 can be driven to rotate through the limit plate 35 in the driving cylinder 3, thereby driving the reclamation auger cylinder 5 to rotate synchronously.

[0027] Since the stopper 51 is slidably connected in the limit plate 35, the depth of the land penetration of the reclamation auger 5 can be adjusted autonomously during the use of the auger, which is convenient for the matching power transmission operation.

[0028] A reclamation screw is arranged on the outer side of the reclamation auger barrel 5, and the soil can be loosened during the rotation of the reclamation screw.

[0029] 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.

[0030] A transverse frame 7 is also installed in the reclamation cylinder 2. 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.

[0031] Two hydraulic cylinders 72 are symmetrically fixed on the bottom side of the middle plate 71, and 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 cylinder 5. An annular clamping plate 37 is fixed to the top of the reclamation auger cylinder 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.

[0032] Specifically, before the mine land reclamation is carried out, the direction of the L-shaped plate 73 is adjusted by using the steering motor so that the L-shaped plate 73 and the clamping plate 37 are clamped together, 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 reclamated, after the mobile base 1 moves to a suitable 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.

[0033] The above-mentioned control method for land reclamation equipment in green mines comprises the following steps: First, the mobile base 1 is used to drive the reclamation cylinder 2 to move to the surface of the mine land to be reclaimed and fertilized, and then different types of fertilizers are respectively put into different fertilizer cavities in the fertilizer box 4, and the single fertilizer application amount of the fertilizer in the fertilizer box 4 is controlled by the discharge control valve plate 43, and different fertilizers are sent to the mixing cavity 31; Then, the driving motor 6 is started, and the driving motor 6 drives the pulley 33 to rotate through the belt loop of the driving wheel 61. When the pulley 33 rotates, it can drive the driving cylinder 3 to rotate synchronously. When the driving cylinder 3 rotates, it can synchronously drive the reclamation auger cylinder 5 to rotate under the action of the block 51 and the limit plate 35. When the reclamation auger cylinder 5 rotates, the outer reclamation spiral drills into the deep layer of the mine soil. At the same time, the rotation of the driving cylinder 3 can synchronously drive the mixing of the fertilizer in the mixing chamber 31. After the reclamation auger 5 drills into the mine land to a preset depth, the driving motor 6 stops rotating, 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 driving cylinder 3, specifically, the mixed fertilizer is delivered to the fertilizer delivery chamber formed between the intermediate cylinder 52 and the driving cylinder 3; Then, the fertilizer outlet 53 at the bottom of the reclamation auger barrel 5 is opened, and the driving motor 6 is controlled to rotate in the reverse direction. When the driving motor 6 rotates in the reverse direction, the reclamation auger barrel 5 can be driven to rotate in the reverse direction through the driving 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, and the reclamation auger barrel 5 rises under the action of the reverse thrust; When the deep soil of the mine land becomes loose, the relative force between the reclamation spiral and the outer side of the reclamation auger 5 is insufficient, and the reclamation auger 5 stops rising and rotating in place, the loosening operation is completed. At the same time, the mixed fertilizer in the fertilizer feeding cavity can be applied into the longitudinal soil layer through the fertilizer outlet 53 when it is moved out, so that the longitudinal deep fertilization operation can be carried out while loosening the soil, completing the reclamation operation of the mine land; 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 raised to reset the reclamation auger barrel 5, that is, the reclamation auger barrel 5 is at the highest point. The position of the movable base 1 is adjusted again, and the reclamation barrel 2 is moved to the next operating point for cyclic operation. This is efficient and convenient.
