Description

Technical Field

[0001] The invention relates to the technical field of mine filling, and in particular to a stirring device for efficiently mixing mine filling materials. Background Art

[0002] While mining brings resources, it may also cause a series of environmental problems and safety hazards, such as surface collapse or landslides. In order to deal with this problem, ground pressure management is generally carried out by filling the mine with filling materials to suppress surface subsidence and surrounding rock collapse, thereby protecting the ecological and environmental balance of the mining site. At present, when preparing filling materials, the pulping function of the pulping equipment is often single and the effect is low. It is impossible to mix the mortar effectively, quickly and evenly, resulting in low pulping efficiency and affecting the filling quality.

[0003] In order to solve the above problems, some research and patent technologies at home and abroad have proposed a variety of improvement plans. For example, Chinese Patent Publication No. CN114953177B discloses a mixing pulping device and method for mine filling, the device includes a sand bin, a main mixing mechanism, an auxiliary mixing mechanism and an adjustment mechanism. This patent can improve the mixing uniformity and pulping speed to a certain extent through the cooperation of the main mixing mechanism and the auxiliary mixing mechanism, but there is still the problem of fixing the angle of the mixing shaft. Since there will be more particles in the filling material, the direct operating resistance of the mixing shaft is large when the filling material is stirred in the initial stage, and it is easy to cause wear to the mixing shaft. Since the mixing shaft cannot be adjusted, in the later stage of stirring the filling material, the mixing shaft cannot be accurately adjusted according to the different states of the filling material, so that the mixing efficiency and quality of the equipment will be affected in the later stage.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1 , Figures 3 to 8 and Fig.10As shown: A mixing device for efficient mixing of mine filling materials, comprising a horizontal mixing barrel 1 and a retractable mixing shaft 11 arranged in the horizontal mixing barrel 1, one end of the horizontal mixing barrel 1 is provided with a driving mechanism 2 which is transmission-connected to one end of the mixing shaft 11, and the other end of the horizontal mixing barrel 1 is fixedly provided with a connecting frame 12 which is rotationally connected to the other end of the mixing shaft 11, the connecting point of the mixing shaft 11 and the connecting frame 12 is on the axis of the horizontal mixing barrel 1, and the mixing shaft 11 is a retractable structure; the driving mechanism 2 comprises a transmission shaft 21 which can extend along the radial direction of the horizontal mixing barrel 1, and a gear 21 which is slidably provided with a gear 21 which is rotationally connected to the transmission shaft 21 The coupling 211 is transmission-connected to the shaft 21, and the coupling 211 is transmission-connected to the stirring shaft 11; the transmission shaft 21 has a first end close to the barrel wall of the horizontal stirring barrel 1 and a second end close to the center of the horizontal stirring barrel 1; the driving mechanism 2 also includes an annular transmission frame 22 transmission-connected to the first end, an inner rotating bracket 23 for mounting the transmission shaft 21, and a driver 221 arranged on the outside of the horizontal stirring barrel 1 and transmission-connected to the annular transmission frame 22; when the driver 221 transmits power to the transmission shaft 21 through the annular transmission frame 22 for self-rotation, the transmission shaft 21 revolves around the axis of the horizontal stirring barrel 1 with the inner rotating bracket 23.

[0034] The driver 221 transmits power to the transmission shaft 21 through the annular transmission frame 22, driving the transmission shaft 21 to rotate. At the same time, the transmission shaft 21 revolves around the axis of the horizontal mixing barrel 1 with the rotating bracket 23, so that the transmission shaft 21 can drive the coupling 211 to rotate around the axis of the mixing barrel 1 with the transmission shaft 21. Since one end of the mixing shaft 11 is connected to the coupling 211 for transmission, and the other end of the mixing shaft 11 is connected to the connecting frame 12 for rotation, both ends of the mixing shaft 11 are provided with universal joints, and the rotation connection with the coupling 211 and the connecting frame 12 is realized through the universal joints, and the connection point between the mixing shaft 11 and the connecting frame 12 is on the axis of the horizontal mixing barrel 1. At this time, the coupling 211 can slide along the radial direction of the horizontal mixing barrel 1 through the sliding setting, thereby driving the mixing shaft 11 to make corresponding adjustments, so that the mixing shaft 11 can rotate around the axis of the horizontal mixing barrel 1 in an inclined posture and can also realize self-rotation. Since the stirring shaft 11 is a retractable structure, the inclination angle of the stirring shaft 11 can be adjusted according to the needs during the stirring process by adjusting the position of the coupling 211 on the transmission shaft 21 .

[0035] In the initial stage of stirring, since the filling material contains a large amount of particles, these particles are easily deposited at the bottom of the horizontal stirring barrel 1. At this time, the inclined stirring shaft 11 can effectively drive the particles settled at the bottom of the barrel to be stirred, avoiding the deposition and aggregation of particles, thereby reducing the resistance in the initial stage of stirring and reducing the wear of the stirring shaft 11.

[0036] As the stirring time increases, the particles will gradually disperse. The coupling 211 slides along the radial direction of the horizontal stirring barrel 1, and the angle of the stirring shaft 11 is gradually adjusted to a state that is nearly parallel to the axis of the horizontal stirring barrel 1, thereby entering the homogenous stirring stage. At this time, the various materials in the filling material are fully stirred and mixed, thereby achieving an efficient homogenous stirring effect; thereby improving the stirring efficiency and ensuring the uniformity and stability of the materials.

[0037] The stirring shaft 11 in the traditional stirring equipment usually has a fixed angle or can only move in a small range, which is difficult to adapt to different stirring needs. The present device drives the stirring shaft 11 through the sliding of the coupling 211, so that the inclination angle of the stirring shaft 11 can be adjusted, and the angle of the stirring shaft 11 can be flexibly adjusted according to the different states of the filling material and the needs during the stirring process, thereby enhancing the adaptability and effect of the stirring. By effectively reducing the initial stirring resistance and alleviating the wear of the stirring shaft 11, the present device can significantly extend the service life of the stirring equipment and reduce maintenance costs, thereby making the stirring process more efficient, reducing the time and energy consumption required for stirring, improving the overall working efficiency of the equipment while also reducing energy consumption.

[0038] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown: a first mounting plate 231 extending radially toward the annular transmission frame 22 along the horizontal mixing barrel 1 is arranged on the inner rotating bracket 23, the coupling 211 is slidably arranged on the first mounting plate 231, and the transmission shaft 21 is rotatably arranged on the first mounting plate 231.

[0039] By setting the first mounting plate 231 on the inner rotating bracket 23, the transmission shaft 21 can be installed and rotated more stably, avoiding transmission instability or error problems that may occur during the operation of the equipment, allowing the equipment to run smoothly, reducing damage caused by friction and unstable movement, effectively extending the service life of the equipment, reducing the frequency of repair and replacement of parts, and reducing maintenance costs.

[0040] By setting the first mounting plate 231, the guiding direction of the coupling 211 sliding is ensured to be accurate, and the coupling 211 is prevented from being offset or out of position, so that the adjustment of the coupling 211 is more precise. The sliding of the coupling 211 can be limited to ensure that the sliding of the coupling 211 is within a predetermined range, and excessive sliding or position errors are prevented, thereby ensuring that the connection between the coupling 211 and the transmission shaft 21 is adjusted at the correct point, so as to achieve precise control of the angle of the stirring shaft 11, thereby achieving more precise adjustment between the transmission shaft 21 and the coupling 211, ensuring the gradual adjustment of the angle of the stirring shaft 11, especially during the stirring process, can more accurately control the mixing state and stirring effect of the materials, thereby improving the stability and efficiency of the stirring process.

[0041] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown: a second mounting plate 232 extending along the length direction of the first mounting plate 231 is provided on one end of the first mounting plate 231 away from the annular transmission frame 22, and a driving shaft 2321 for driving the coupling 211 to slide is provided on the second mounting plate 232, and the driving shaft 2321 is a telescopic structure.

[0042] By providing the second mounting plate 232, the coupling 211 can be moved from the end of the first mounting plate 231 to a position coaxial with the axis of the inner rotating bracket 23, thereby enabling the stirring shaft 11 connected to the coupling 211 to be adjusted from the initial tilted posture to the coaxial posture with the axis of the horizontal stirring barrel 1. During the stage of homogenizing the filling material with the stirring shaft 11, since the stirring shaft 11 is coaxial with the axis of the horizontal stirring barrel 1, the stirring shaft 11 can stir the filling material more evenly, avoiding the uneven stirring phenomenon caused by the tilted posture of the stirring shaft 11, and can improve the mixing effect of the filling material during the stirring process, ensuring the uniformity and quality of the filling material.

[0043] In addition, by arranging the drive shaft 2321 on the second mounting plate 232 and using its telescopic structure to drive the coupling 211 to slide, the sliding position of the coupling 211 on the transmission shaft 21 can be accurately controlled. The telescopic function of the drive shaft 2321 enables the coupling 211 to be adjusted in the length direction of the first mounting plate 231, thereby achieving precise adjustment of the inclination angle of the stirring shaft 11, optimizing the motion trajectory of the stirring shaft 11, and ensuring the working effect of the stirring shaft 11 at different stages.

[0044] The precise angle adjustment and optimized motion trajectory of the stirring shaft 11 make the stirring process more efficient and avoid unnecessary energy consumption. By reducing uneven and inefficient operations during the stirring process, the overall production efficiency and energy utilization of the equipment are improved.

[0045] like Figure 3 , Figure 4 , Figure 6 and Figure 7 , Fig.10 and Fig.12 As shown: a mounting seat 2322 is provided on the second mounting plate 232, a cavity 2323 for liquid circulation is provided between the mounting seat 2322 and the inner rotating bracket 23, a driving shaft 2321 is installed on the mounting seat 2322, and a hydraulic driving member 2324 is provided on the outer wall of the horizontal mixing barrel 1 for driving the driving shaft 2321 to move through the liquid in the cavity 2323.

[0046] The mounting seat 2322 is a hollow structure, and the interior of the mounting seat 2322 is connected to the cavity 2323. The hydraulic drive component 2324 applies pressure to the hydraulic oil in the cavity 2323, thereby driving the drive shaft 2321 on the mounting seat 2322 to move, pushing the drive shaft 2321 on the mounting seat 2322 to move, and then pushing the movement of the coupling 211 connected to the drive shaft 2321, so that the coupling 211 slides along the first mounting plate 231, and drives the angle adjustment of the stirring shaft 11 through the movement.

[0047] The hydraulic oil flow is controlled by the hydraulic drive member 2324, thereby accurately pushing the drive shaft 2321 to move axially along the cavity 2323, so that the coupling 211 slides on the first mounting plate 231, thereby adjusting the inclination angle of the stirring shaft 11. This method can adjust the angle of the stirring shaft 11 according to the state of the filling material, and realize a precise stirring process.

[0048] By adjusting the driving shaft 2321 by the hydraulic drive 2324, the angle adjustment process of the stirring shaft 11 can be made smoother, reducing the stirring resistance and mechanical loss that may be caused by inappropriate angles or inaccurate adjustments, thereby extending the service life of the equipment. The angle adjustment mechanism of the stirring shaft 11 is simplified, avoiding the complex motion structure in the traditional mechanical adjustment system, reducing the difficulty of maintenance and operation, and making the equipment more stable and reliable. The equipment can adapt to different filling material states, especially when the material contains different particle sizes or densities, by flexibly adjusting the inclination angle of the stirring shaft 11, the stirring effect of the filling material is optimized to ensure an efficient mixing process.

[0049] like Figure 3 , Figure 4 , Figures 6 to 8 , Fig.10 and Fig.12As shown: a fixing hole 2111 is provided on one side of the coupling 211 close to the end of the horizontal mixing barrel 1, a fixing groove 13 is provided at the axis center of the end of the horizontal mixing barrel 1, and a fixer 131 elastically connected thereto is provided in the fixing groove 13, and the fixer 131 can move along the axis of the horizontal mixing barrel 1, and the fixer 131 is controlled by electromagnetic.

[0050] The coupling 211 is provided with a fixing hole 2111 for cooperating with the fixer 131 at the end of the horizontal mixing barrel 1. When the coupling 211 is moved to a position coaxial with the axis of the horizontal mixing barrel 1, the fixer 131 is elastically connected to the fixing groove 13, so that the fixer 131 can be inserted into the fixing hole 2111 of the coupling 211 along the axis direction of the horizontal mixing barrel 1, thereby fixing the coupling 211.

[0051] The holder 131 is electromagnetically controlled, and the electromagnetic control drives the holder 131 to move along the axis of the horizontal mixing barrel 1 by controlling the force of the electromagnet. The electromagnet can accurately control the holder 131 by generating suction or repulsion, thereby achieving the fixation and release of the coupling 211. This method ensures that when the coupling 211 is coaxial with the axis of the horizontal mixing barrel 1, it will not be offset or moved unnecessarily, thereby ensuring the stability of the mixing shaft 11, thereby improving the stability and accuracy of the mixing process.

[0052] Electromagnetic control can simplify the operating process, reduce manual intervention, and improve the automation level of the equipment.

[0053] like Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig.10 and Fig.11 As shown: the coupling 211 includes an installation box 2112 and a rotating shaft 21121 arranged in the installation box 2112, a first bevel gear 21122 is sleeved on the rotating shaft 21121, a second bevel gear 21123 meshingly connected to the first bevel gear 21122 is arranged next to the first bevel gear 21122, the second bevel gear 21123 is sleeved on the end of the transmission shaft 21, and the stirring shaft 11 is transmission-connected to the rotating shaft 21121.

[0054] It should be noted that the annular transmission frame 22 is fixedly connected to the end of the horizontal mixing barrel 1, and a rotatable bevel gear ring 222 is arranged inside the annular transmission frame 22, and the inner edge and outer edge of the bevel gear ring 222 are provided with meshing teeth. The driver 221 is installed on the outer wall of the bedroom horizontal mixing barrel 1, and a third bevel gear 2211 is sleeved on the driver 221. A fourth bevel gear 2212 is arranged on the end of the transmission shaft 21 away from the coupling 211. The third bevel gear 2211 and the fourth bevel gear 2212 are both meshed and connected with the bevel gear ring 222, and the third bevel gear 2211 is driven to rotate by the driver 221, and the third bevel gear 2211 can drive the bevel gear ring 222 to rotate, and the rotation of the bevel gear ring 222 drives the fourth bevel gear 2212 to rotate, and the rotation of the fourth bevel gear 2212 drives the rotation of the transmission shaft 21.

[0055] The transmission shaft 21 can drive the second bevel gear 21123 to rotate by rotating, and the rotation of the second bevel gear 21123 drives the first bevel gear 21122 meshing with it to rotate, thereby driving the rotating shaft 21121 to rotate. Since universal joints are provided at both ends of the stirring shaft 11, the rotation of the rotating shaft 21121 can drive the rotation of the stirring shaft 11.

[0056] Since the transmission shaft 21 is rotatably connected to the end of the horizontal mixing barrel 1 through the inner rotating bracket 23, when the bevel gear ring 222 drives the fourth bevel gear 2212 to rotate, it will also drive the fourth bevel gear 2212 to rotate around the axis of the bevel gear ring 222, thereby realizing the self-rotation of the transmission shaft 21 and the revolution around the axis of the horizontal mixing barrel 1. In order to ensure the sealing, a rotatable annular plate 2213 is provided on the annular transmission frame 22, and the annular plate 2213 is sleeved on the annular transmission frame 22. The transmission shaft 21 passes through the annular plate 2213 and is meshedly connected with the bevel gear ring 222 through the fourth bevel gear 2212, so that the filling material will not affect the operation of the driving mechanism 2 during the mixing process, thereby improving the stability of the driving mechanism 2.

[0057] Through the meshing connection between the first bevel gear 21122 and the second bevel gear 21123, efficient power transmission is achieved, ensuring high power transmission efficiency, while being able to withstand a large torque load, ensuring the smooth operation of the mixing equipment and long-term efficient work.

[0058] By combining the first bevel gear 21122, the second bevel gear 21123 with the rotating shaft 21121 and the transmission shaft 21, the structural design of the coupling 211 is optimized, making the overall equipment more compact and occupying less space. Especially for equipment applications with limited space, it helps to improve the layout flexibility and installation convenience of the equipment. The above transmission method has good load-bearing capacity and can adapt to a high-load working environment. Especially when processing high-viscosity or large-particle filling materials, it can effectively ensure the stable operation of the mixing equipment and prevent the equipment from excessive wear or stagnation under high load.

[0059] like Figure 3 , Figure 4 , Figures 6 to 10 and Fig.13 As shown: the stirring shaft 11 includes a fixed section 111 rotatably connected to the connecting frame 12 and a movable section 112 slidable in the fixed section 111 , and a portion of the movable section 112 located in the fixed section 111 is provided with a plurality of foldable first stirring blades 1121 .

[0060] By providing a foldable first stirring blade 1121 on the moving section 112 of the stirring shaft 11, the expansion angle and number of the stirring blades can be dynamically adjusted according to the telescopic length of the stirring shaft 11. It should be noted that the fixed section 111 and the moving section 112 are also provided with a plurality of second stirring blades 113. During the stirring process, the first stirring blade 1121 can more effectively adapt to different types of filling materials by folding and unfolding, enhance the stirring effect of the material, and ensure that the filling material can be fully mixed in the initial stirring stage and the homogenization stage.

[0061] The foldable first stirring blade 1121 can automatically adjust its degree of expansion according to the different rheological properties of the filling material, and can be appropriately folded in the initial stage of stirring to reduce resistance; and when stirring to a certain degree, the blades can be unfolded to provide stronger stirring force, thereby optimizing the efficiency of the stirring process. The first stirring blade 1121 can save space when it does not need to be fully expanded. Especially when the material is relatively loose or does not require large-scale stirring, the expansion area of ​​the first stirring blade 1121 can be reduced, reducing the load on the stirring shaft 11 and reducing energy consumption. At the same time, the folding of the first stirring blade 1121 also reduces the collision and friction that may occur during the stirring process, thereby extending the service life of the equipment.

[0062] like Figure 3 , Figure 4 , Figures 6 to 10 and Fig.13As shown: the first stirring blade 1121 is rotatably installed on the moving section 112, and the moving section 112 is provided with a driving ring 1122 that can slide along its axial direction. The driving ring 1122 is rotatably connected with transmission rods 11211 that are the same in number and one-to-one correspondence with the first stirring blade 1121, and one end of the transmission rod 11211 away from the driving ring 1122 is hinged to the middle part of the first stirring blade 1121.

[0063] The movement of the driving ring 1122 along the axis of the moving section 112 can drive the movement of multiple transmission rods 11211 connected thereto. Since the other end of the transmission rod 11211 is hinged to the middle part of the first stirring blade 1121, and the first stirring blade 1121 is rotatably arranged on the moving section 112, the transmission rod 11211 can support the first stirring blade 1121, thereby allowing the first stirring blade 1121 to be adjusted from a state parallel to the axis of the stirring shaft 11 to a state where the first stirring blade 1121 extends radially along the stirring shaft 11, thereby allowing the first stirring blade 1121 to adapt to different types of filling materials, thereby enhancing the stirring effect of the materials and ensuring that the filling materials can be fully mixed in the initial stirring stage and the homogenization stage.

[0064] like Figure 3 , Figure 4 , Figures 6 to 10 and Fig.13 As shown: the driving ring 1122 is provided with a plurality of supporting shafts 11221 equidistantly around its axis, a sealing ring 11222 fixedly connected to the supporting shaft 11221 is provided in the middle portion thereof, a transmission ring 11223 is provided on the end of the supporting shaft 11221 away from the driving ring 1122, the transmission ring 11223 is elastically connected to the end of the fixed section 111 away from the moving section 112, hydraulic oil is provided in the fixed section 111, and the moving section 112 is tightly and slidably connected to the sealing ring 11222.

[0065] The setting of the sealing ring 11222 can prevent the leakage of hydraulic oil, ensure the sealing and stability of the hydraulic oil, and thus avoid the waste and pollution of the hydraulic oil. The improvement of the sealing performance increases the reliability of the equipment and reduces the failure and maintenance cost of the equipment caused by the leakage of hydraulic oil.

[0066] Since hydraulic oil is arranged in the fixed section 111, the hydraulic oil will be squeezed when the movable section 112 slides in the fixed section 111, and the pressure of the hydraulic oil is fully utilized to drive the movement of the transmission ring 11223, and the movement of the transmission ring 11223 drives the movement of the support shaft 11221, and the movement of the sealing ring 11222 and the driving ring 1122 is driven by the support shaft 11221, and the movement of the driving ring 1122 drives the first stirring blade 1121 to expand or contract. This allows the device to accurately control the angle and strength of the first stirring blade 1121 according to the different states of the filling material and the needs of the stirring process, so as to achieve the best stirring effect at different stages.

[0067] Since the extension and retraction of the stirring shaft 11 is achieved through the coupling 211, the stirring shaft 11 can squeeze the hydraulic oil through the movement of the moving section 112 in the fixed section 111, without the need to set up a separate driving source, thereby reducing the investment cost of the equipment.

[0068] like Figures 1 to 4 and Fig.10 As shown, a frame 14 is arranged outside the horizontal mixing barrel 1, and the horizontal mixing barrel 1 is rotatably arranged on the frame 14, and the axis of the horizontal mixing barrel 1 can be rotated from a vertical state to a horizontal state.

[0069] By arranging a frame 14 on the outside of the horizontal mixing barrel 1, the horizontal mixing barrel 1 can be supported by the frame 14 to realize rotation, so that its axis can be rotated from a vertical state to a horizontal state. In the vertical state, the horizontal mixing barrel 1 is suitable for loading materials. Subsequently, the axis of the horizontal mixing barrel 1 is gradually adjusted to a horizontal state, so that the stirring shaft 11 can fully mix the filling material to achieve a homogeneous stirring effect. The discharge port 122 of the horizontal mixing barrel 1 can be set eccentrically, and at the same time, when the horizontal mixing barrel 1 is used to pour the stirred filling material, the stirring shaft 11 can be rotated to the upper side of the horizontal mixing barrel 1, so that the filling material can be better poured out, reducing the obstruction of the stirring shaft 11 to the filling material.

[0070] By adjusting the axis angle of the horizontal mixing barrel 1, the mixing requirements at different stages can be met, further improving the adaptability of the equipment.

[0071] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
