Description

Technical Field

[0001] The present invention relates to the technical field of mine restoration, and more particularly to the technical field of mine restoration material mixing, and in particular to a mixing device for mine restoration backfill materials. Background Art

[0002] my country is a country rich in mineral resources, but with the continuous exploitation of mineral resources, the ecological environment of mines has also been seriously damaged. Disasters such as landslides, mountain torrents and collapse accidents occur from time to time. Mine restoration, also known as mine ecological restoration, is the restoration of the damaged mine ecological environment and the sustainable use of land resources.

[0003] When carrying out ecological restoration in mining areas, it is necessary not only to deal with the topography of the mine, but also to backfill the mountain to avoid collapse. In order to avoid using a single material to backfill and affect the structural strength and recovery speed of the mountain after backfilling, different types of restoration materials need to be mixed and mixed before backfilling;

[0004] For example, the invention with application publication number CN 116537869 A discloses a mine backfilling machine and a backfilling method, which relate to the field of mine backfilling technology. The mine backfilling machine and the backfilling method include a backfilling device, the outer wall of which is movably connected to a conveyor belt, the top of which is fixedly connected to a cross frame, and the outer wall of which is fixedly connected to a processing device. The mine backfilling machine and the backfilling method first hit the processing bin by the gravity of the mud blocks. The setting of the processing bin prevents the mud blocks from directly hitting the conveyor belt, and prevents the mud blocks from generating impact force on the conveyor belt, thereby protecting the conveyor belt and extending the service life of the conveyor belt. The first spring is provided with elasticity, which can buffer the gravity of the soil. When the gravity of the mud blocks hits the processing bin, the gravity of the mud blocks can drive the processing bin to follow the decline. The mud blocks collide with the cutting knife under their own gravity, and the cutting knife cuts the mud blocks.

[0005] Another example is the patent with authorization announcement number CN 216630521 U, which belongs to the field of mine restoration technology, and in particular, a nutrient soil mixing device for mine restoration, including a machine body, a feed port, a mixing mechanism, a guide pipe, a support plate, a base and a spring. The right end of the feed port is connected to the left side of the top of the machine body, the top of the mixing mechanism is fixedly mounted on the right side of the top of the machine body, the top of the guide pipe is connected to the middle of the bottom of the machine body, and the tops of the two support plates close to each other are fixedly connected to the two side surfaces of the bottom of the machine body. The nutrient soil mixing device for mine restoration, through the mixing mechanism, first controls the mixing motor to rotate forward. The mixing motor can drive the main shaft and the main gear to rotate forward at the same time. The main shaft can drive the mixing blades and the guide blades to rotate forward at the same time. The mixing blades can transmit the nutrient soil below upward when they rotate forward, thereby improving the mixing efficiency of the nutrient soil in advance.

[0006] However, combined with the actual working conditions of mine backfilling, the current mixing device for mine repair backfilling materials still has certain disadvantages, such as:

[0007] 1. The current mixing device is not convenient for proportioning different materials when loading. It is necessary to repeatedly load different materials, and the loading system cannot pre-mix materials.

[0008] 2. The general mixing device simply mixes the materials and then discharges them for use. However, in actual use, due to the viscosity of the backfill material, the mixing effect is poor, which is not conducive to ensuring the uniformity of different materials;

[0009] 3. The current mixing device only discharges materials through the discharge port when discharging materials. The discharge position is fixed, which is not conducive to avoiding the leakage of the mixture and is not conducive to quickly backfilling the mixture for use.

[0057] Among them, Figure 1-Figure 4The mixing tank 2 is mounted on the top of the base frame 1, a feed pipe 13 is provided at the top of the mixing tank 2, a stirring shaft 32 is rotatably installed inside the mixing tank 2, and a discharge pipe 35 is provided at the bottom of the mixing tank 2, a flat car 3 is arranged on the left side of the base frame 1, and a feed bin is installed above the flat car 3, the feed bin includes: a feed box 4, a feed hopper 5, a feed cylinder 6, a weighing cylinder 7 and a weighing system 8, the feed box 4 is fixedly installed on the top surface of the flat car 3, and a feed hopper 5 with a bucket-shaped structure is fixedly connected to the top of the feed box 4, and the feed hopper 5 The inside of the flat car 3 is evenly distributed with feeding cylinders 6, and a weighing cylinder 7 is placed inside the feeding cylinder 6. A weighing system 8 is arranged between the feeding cylinder 6 and the weighing cylinder 7. A first telescopic rod 9 is fixedly connected to the inner side of the flat car 3, and a feeding pipe 10 is installed on the side of the feeding bin between the end of the first telescopic rod 9 and the bottom frame 1, and a feeding auger 11 is installed inside the feeding pipe 10. A discharge pipe 12 is connected to the outside of the top of the feeding pipe 10, and the end of the discharge pipe 12 is telescopically connected with a connecting pipe 15 corresponding to the feeding pipe 13;

[0058] In specific application scenarios, such as Figure 1 By extending and retracting the first telescopic rod 9, the flat car 3 can slide left and right through the wheels installed at the bottom thereof, so that the feeding auger 11 installed at the bottom of the feeding pipe 10 can correspond to the feeding pipe 13, and the connecting pipe 15 can be connected to the feeding pipe 13. When feeding, Figure 4 The backfill material is poured into the inside of the weighing cylinder 7. The bottom of the weighing cylinder 7 is in contact with the feed cylinder 6 through the weighing system 8. The material amount inside the weighing cylinder 7 can be weighed by the weighing system 8. When the material amount inside the weighing cylinder 7 reaches the amount of the adapted ratio, the feeding is stopped, and the electromagnetic valve at the bottom of the inner side of the weighing cylinder 7 is opened, so that the backfill material inside the weighing cylinder 7 is poured into the inside of the feed hopper 5.

[0059] By adopting the above technical solution, the problem that the mixing device for mine restoration backfill materials under the existing technical background cannot quickly load different types of raw materials in proportion can be solved, thereby achieving the goal of meeting the requirements of different material proportions of backfill materials for ecological restoration in different areas of mines, thereby improving the efficiency of mine backfill and accelerating the speed of mine ecological restoration.

[0060] Among them, Figure 1 , Figure 4 and Figure 5 The middle connecting tube 15 is connected to the discharge tube 12 through the first telescopic tube 14. The first telescopic tube 14 is a telescopic structure. The outer side of the connecting tube 15 is fixedly connected with the second telescopic rod 16, and the end of the second telescopic rod 16 is fixedly connected to the outer side of the end of the discharge tube 12. The outer side of the connecting tube 15 is symmetrically fixed with a fixing block 17. A limit block 19 facing the discharge tube 12 is fixed above the fixing block 17. The outer side of the discharge tube 12 is fixed with a sliding rod 18 sleeved on the outer side of the limit block 19;

[0061] In specific application scenarios, such as Figure 5 By extending the second telescopic rod 16, the top end of the second telescopic rod 16 can drive the connecting tube 15 to extend downward, so that the connecting tube 15 is engaged with the feeding tube 13, so as to facilitate the transportation of the backfill raw materials to the inside of the mixing tank 2. At the same time, a fixing block 17 is fixed on the side of the connecting tube 15, and a sliding structure is formed between the sliding rod 18 fixed on the inner side of the fixing block 17 and the limiting block 19 on the outer side of the discharge tube 12, so that when the connecting tube 15 is extended and slid, it is always limited by the limiting block 19 on the sliding rod 18, which can ensure that the telescopic direction of the connecting tube 15 is fixed, avoid bending, and ensure the feeding use;

[0062] By adopting the above technical solution, it is possible to solve the problem that the feeding mechanism and the mixing system of the mixing device for mine repair backfill materials are fixed together under the existing technical background, resulting in a large volume, inconvenient disassembly and movement, and inconvenient adjustment and use of the mixing system. It is conducive to connecting during loading and disconnecting after loading is completed, and the mixing tank 2 can be rotated for use.

[0063] Among them, Figure 1 and Figure 6The middle support frame 20 is rotatably connected to the top of the base frame 1, a first fixing frame 21 is fixedly installed on the surface of the support frame 20, and a first roller 22 is rotatably installed on the top of the first fixing frame 21, the first fixing frame 21 is engaged with a boss 23 protruding from the outer side of the mixing tank 2 through the first roller 22, a second fixing frame 24 is fixedly connected to the outer side of the support frame 20, and a second roller 25 engaged with the boss 23 is rotatably installed on the inner side of the second fixing frame 24, a connecting arm 26 is fixedly installed on the outer side of the support frame 20 and the second fixing frame 24, and the support frame 20 and the second fixing frame 24 are fixedly connected by bolts of the connecting arm 26, a connecting plate 27 is fixedly installed on the outer side of the second fixing frame 24, and the second fixing frames 24 and the second fixing frames 24 form an integrated structure through the connecting plate 27;

[0064] In specific application scenarios, such as Figure 6 The first fixing frame 21 is fixed to the outer surface of the support frame 20, and the first roller 22 is rotatably installed on the inner side of the first fixing frame 21 to engage with the boss 23 protruding from the outer side of the mixing tank 2, so that the mixing tank 2 can stably roll itself above the support frame 20 under the limit of the first roller 22 through the engagement between the boss 23 and the first roller 22. At the same time, the connecting arm 26 is fixed on the outer side of the first fixing frame 21, and the first fixing frame 21 is fixed to the second fixing frame 24 through the connecting arm 26, and the second fixing frame 24 is also engaged with the boss 23 through the second roller 25, so that the first The fixing frame 21 and the second fixing frame 24 are symmetrically distributed on the outside of the mixing tank 2. At the same time, the second fixing frame 24 units are fixed by connecting plates 27, and then the mixing tank 2 is enclosed by the support frame 20, the first fixing frame 21, the connecting arm 26, the second fixing frame 24 and the connecting plate 27. The first roller 22 and the second roller 25 are engaged with the boss 23 to ensure the rolling of the mixing tank 2 inside the enclosure structure, and the mixing tank 2 is limitedly installed on the surface of the support frame 20 through the enclosure structure, so that when the support frame 20 rotates above the base frame 1, the stability of the mixing tank 2 is ensured.

[0065] By adopting the above technical solution, the problem that the mixing tank 2 of the mixing device for mine repair backfill materials under the existing technical background cannot be adjusted in angle can be solved. The mixing tank 2 can be placed obliquely or vertically, which can help reduce the stirring and mixing pressure and facilitate discharge and use.

[0066] Among them, Figure 1 , Figure 2 , Figure 3 and Figure 7The inner and outer gear rings 28 are protrudingly arranged on the outer side of the end of the mixing tank 2, and the outer side of the outer gear ring 28 is meshedly connected with a driving gear 29, a pulley 30 is fixed to the top of the driving gear 29, and the pulley 30 is connected to the stirring shaft 32 through a transmission belt 31, a stirring rod 33 is fixedly installed on the outer side of the top of the stirring shaft 32 in a spiral shape, and a stirring blade 34 with a spiral structure is fixed to the outer side of the bottom of the stirring shaft 32, and the outer side edge of the stirring blade 34 is in contact with the inner wall of the mixing tank 2.

At the same time, a pulley 30 is fixed to the outer side of the driving gear 29. Figure 3 The transmission belt 31 and the stirring shaft 32 can be connected by the pulley 30 for transmission, so that the stirring shaft 32 can be driven to rotate inside the mixing tank 2.

At the same time, the stirring blade 34 arranged at the bottom end of the stirring shaft 32 has a spiral structure, and the stirring blade 34 can turn over the raw materials at the bottom of the mixing tank 2 to ensure uniform mixing.

[0068] By adopting the above technical scheme, it is possible to solve the problem that the mixing device for mine repair backfill materials under the existing technical background is not convenient for self-rotation and mixing, which is not conducive to improving the mixing efficiency of the backfill raw materials. It is conducive to quickly mixing the backfill raw materials. At the same time, the forward rotation of the stirring blade 34 can turn the material, and the reverse rotation of the stirring blade 34 is convenient for the discharge of the material and auxiliary discharge.

An air bag 43 is fixedly installed on the outside of the bottom of the adjusting tube 37.

[0070] In specific application scenarios, such as Figure 8 and Fig. 9In the embodiment of the present invention, when mixing is completed, the mixing tank 2 is maintained in a vertical state, and the adjusting tube 37 is rotated on the outside of the discharge tube 35 so that the card slot 38 set on the top of the connecting plate 27 is disengaged from the card buckle 39 on the outside of the discharge tube 35, and then the adjusting tube 37 is pulled so that the adjusting tube 37 is extended through the second telescopic tube 36 and the discharge tube 35, and the adjusting tube 37 is stretched to the discharge position. At the same time, a fixing plate 40 is fixed to the outside of the top of the adjusting tube 37, and the direction of the limiting rod 42 is adjusted by rotating the connecting block 41 on the inner side of the fixing plate 40, and the limiting rod 42 is tightened to press the limiting rod 42 against the side of the discharge position, so that the adjusting tube 37 can be stably limited, and the airbag 43 can be inflated so that the airbag 43 expands between the adjusting tube 37 and the side wall of the discharge position, so that sealing can be performed to avoid dust.

[0071] By adopting the above technical solution, the problem that the discharge position of the mixing device for mine repair backfill materials is fixed under the existing technical background and dust is easily generated during discharge can be solved. The position of the regulating pipe 37 can be directly adjusted, and dust can be avoided by sealing, thereby improving the working environment.

[0072] Among them, Figure 1 , Figure 2 , Fig.10 and Fig.11 A support plate 44 is provided on the outer side of the bottom end of the middle support frame 20, and the support plate 44 is vertically connected to the outer side of the bottom end of the support frame 20. A support platform 45 is fixedly installed on the surface of the support plate 44, and a rotatable ball 46 is embedded and installed on the inner side of the support platform 45. The mixing tank 2 is rotatably placed above the support platform 45 through the ball 46. A third telescopic rod 47 is connected to the bottom surface of the support frame 20, and the bottom end of the third telescopic rod 47 is connected to the bottom of the bottom frame 1. The support frame 20 forms an adjustable rotating structure on the top of the bottom frame 1 through the third telescopic rod 47. A cross bar 48 is fixedly installed on the top end of the outer side of the bottom frame 1, and the cross bar 48 is used to contact and place the bottom surface of the support plate 44;

[0073] In a specific application scenario, by extending and retracting the third telescopic rod 47, it is convenient to drive the support frame 20 to rotate above the base frame 1, so that the angle of the mixing tank 2 can be adjusted. The mixing tank 2 is installed on the outside of the support frame 20 via the support frame 20, the first fixed frame 21, the connecting arm 26, the second fixed frame 24 and the connecting plate 27. The bottom of the support frame 20 is vertically fixed with a support plate 44. The support plate 44 is installed with a ball 46 through a support platform 45 to support the bottom of the mixing tank 2. When the mixing tank 2 is in a vertical state, the pressure of the mixing tank 2 on the first roller 22 and the second roller 25 can be reduced to avoid structural deformation. At the same time, when the support plate 44 is flipped horizontally, it is mounted on the top of the cross bar 48 and can be supported by the base frame 1. When the support frame 20 is placed obliquely, it is also in contact with the base frame 1, which is convenient for the third telescopic rod 47 to adjust the support frame 20 for stable use.

[0074] By adopting the above-mentioned technical scheme, the problem that the mixing device for mine repair backfill materials under the existing technical background cannot adjust the angle of the mixing tank 2 can be solved. The mixing tank 2 can be directly placed obliquely, and when it rotates or stirs through the stirring shaft 32, the resistance during stirring can be reduced, and the internal stirring shaft 32 can be avoided from breaking. At the same time, the stirring and mixing efficiency can be accelerated. When the mixing tank 2 is placed vertically, it is convenient to turn the material over and it is also convenient for discharging and use.
