[0031] See also Figures 1 to 9 , an embodiment of the present application provides a screw stirring and spraying machine for mining, which may include: a base frame 1, a stirring system 2, a driving mechanism 3, a feeding mechanism 4, a stator and rotor assembly 5, a hopper outlet 6, a discharge port assembly 7 and a tensioning screw 8, the stirring system 2 is fixed on the base frame 1; the driving mechanism 3 is arranged on the base frame 1; the input end of the feeding mechanism 4 is connected to the output end of the driving mechanism 3, and the feeding mechanism 4 is connected to the stirring system 2; the input end of the stator and rotor assembly 5 is connected to the output end of the feeding mechanism 4; one side of the hopper outlet 6 is connected to the feeding mechanism 4, and the other side is connected to the stator and rotor assembly 5; the discharge port assembly 7 is arranged at the end of the stator and rotor assembly 5; one end of the tensioning screw 8 is detachably connected to the hopper outlet 6, and the other end is cooperatively connected to the discharge port assembly 7.

[0032] It should be noted that a plurality of universal wheels are provided on the side of the chassis 1 facing the ground, so that the mining screw stirring sprayer involved in this application can be pushed to the position where mortar needs to be sprayed, thereby facilitating its movement.

[0033] In this embodiment, when spraying mortar underground in a coal mine, the mortar is first injected into the stirring system 2 for stirring. The evenly stirred mortar is then transported to the feeding mechanism 4. Under the action of the driving mechanism 3, the feeding mechanism 4 starts to operate, and the feeding mechanism 4 transports the mortar to the stator and rotor assembly 5, and finally discharges it from the stator and rotor assembly 5 and discharges it from the discharge port assembly 7, spraying the mortar on the designated wall. In the above process, long-term spraying operations will cause certain wear on the stator and rotor assembly 5. When the stator and rotor assembly 5 is worn to a certain extent, it needs to be replaced. When replacing the stator and rotor assembly 5, it is only necessary to remove one end of the tensioning screw 8 from the hopper outlet 6 and the other end of the tensioning screw 8 from the discharge port assembly 7, and then the stator and rotor assembly 5 can be removed, so that a new stator and rotor assembly 5 can be installed on the mining screw stirring sprayer. The above connection method can completely tighten the stator and rotor assembly 5 and is more convenient for disassembly and assembly of the stator and rotor assembly 5.

[0034] See also Figure 2 The stirring system 2 may include: a fixed frame 201, a stirring chamber 202, a rotating shaft 203, a stirring blade 204 and a motor 205, wherein the stirring chamber 202 is fixed to the side of the fixed frame 201 facing the base frame 1, and the stirring chamber 202 is connected to the feeding mechanism 4; the rotating shaft 203 is rotatably set on the fixed frame 201, and the rotating shaft 203 passes through the fixed frame 201 and extends into the interior of the stirring chamber 202; the stirring blade 204 is fixedly connected to the outer periphery of the rotating shaft 203 and is located in the stirring chamber 202; the motor 205 is arranged on the side of the fixed frame 201 away from the base frame 1 and is connected to the rotating shaft 203.

[0035] In this embodiment, the structure of the mixing system 2 is further defined. When mixing the mortar, the motor 205 is first started. Driven by the motor 205, the rotating shaft 203 begins to rotate. The rotation of the rotating shaft 203 drives the mixing blades 204 to rotate within the mixing chamber 202, thereby stirring the mortar in the mixing chamber 202 for a more uniform mixture. Furthermore, the provision of the fixing frame 201 facilitates the installation of the mixing chamber 202, the rotating shaft 203, the mixing blades 204, and the motor 205.

[0036] See also Figure 2 The stirring system 2 may further include: a reducer 206 , wherein the reducer 206 is connected to the motor 205 .

[0037] Further, by arranging reducer 206 and making reducer 206 match with motor 205, it is mainly for better controlling output speed and increasing torque. Reducer 206 is directly installed after motor 205, and is fixed together by modes such as coupling or direct flange docking between the two. The power that motor 205 produces is transferred to other components of stirring system 2, such as rotating shaft 203 or stirring blade 204 etc. after regulating via reducer 206. This mode can not only improve efficiency, but also reduce wear and tear, and protect motor 205 from overload damage.

[0038] See also Figure 8 、 Figure 9 The driving mechanism 3 may include: a motor 301 and a reducer 302, wherein the motor 301 is fixed on the base frame 1, and the motor 301 has an output shaft; the input end of the reducer 302 is connected to the output shaft, and the output end is connected to the feeding mechanism 4.

[0039] Specifically, motor 301 is fixed to chassis 1, ensuring the stability and safety of the entire system. Reducer 302 is directly connected to the output shaft of motor 301, typically via a key connection or flexible coupling, to ensure synchronous rotation between the two. This design reduces the high speed transmitted from motor 301 to a low speed suitable for the operation of feed mechanism 4 and increases output torque, thereby making the feeding process smoother and more efficient. The output end of reducer 302 is connected to feed mechanism 4, transmitting the adjusted power to feed mechanism 4 to promote material movement or processing.

[0040] See also Figure 8 The feeding mechanism 4 may include: a feeding shell 403, a feeding shaft 401 and a spiral blade 402, wherein the feeding shell 403 is connected to the stirring system 2, the feeding shaft 401 is located in the feeding shell 403, one end of the feeding shaft 401 is connected to the output end of the reducer 302, and the other end is connected to the stator and rotor assembly 5; the spiral blade 402 is arranged on the outer periphery of the feeding shaft 401.

[0041] Among them, the feed housing 403 serves as the outer shell of the entire feed mechanism 4, and is used to accommodate the feed shaft 401 and the spiral blade 402, and prevent mortar leakage. At the same time, it also plays a role in protecting internal components. The feed housing 403 is usually made of metal material and has a certain degree of corrosion resistance or wear resistance according to the application environment. One end of the feed shaft 401 is connected to the output end of the reducer 302, so that the power transmitted by the motor 301 through the reducer 302 can drive the feed shaft 401 to rotate; the other end of the feed shaft 401 is connected to the stator and rotor assembly 5, which is to further transmit power to the given rotor assembly 5. At the same time, the feed shaft 401 serves as a support for the spiral blade 402 and rotates with the spiral blade 402 to push the mortar forward. The spiral blade 402 is set on the outer periphery of the feed shaft 401. When the feed shaft 401 rotates, the spiral blade 402 rotates accordingly, and the mortar moves forward along the inner wall of the feed housing 403 through the pushing action.

[0042] It should be noted that when the motor 301 is started and transmits power to the feed shaft 401 through the reducer 302, the feed shaft 401 drives the spiral blade 402 to rotate. The mortar enters the feed housing 403 from the feed inlet and is then pushed by the rotating spiral blade 402 in a predetermined direction until it reaches the discharge outlet.

[0043] See also Figure 8 、 Figure 9 The stator-rotor assembly 5 may include: a stator-rotor housing 501 and a stator-rotor 502 , wherein the stator-rotor 502 is disposed in the stator-rotor housing 501 , and one end of the stator-rotor 502 is connected to the feed shaft 401 .

[0044] In this embodiment, the stator-rotor housing 501 serves as the outer shell of the entire stator-rotor assembly 5. It not only protects the internal stator-rotor 502 from the external environment, but also provides support and guides the flow of mortar. The stator-rotor 502, housed within the stator-rotor housing 501, generates centrifugal force or axial thrust, thereby moving the mortar from one location to another. Specifically, when the motor 301 is started and transmits power to the feed shaft 401 via the reducer 302, the feed shaft 401 not only drives the spiral blades 402 to rotate to transport the mortar, but also drives the stator-rotor 502 to rotate.

[0045] See also Figure 5 The hopper outlet 6 may include: a hopper outlet flange 601 and multiple tensioning screw fixing plates 602, wherein one side of the hopper outlet flange 601 is connected to the feeding mechanism 4, and the other side is connected to the stator and rotor assembly 5; multiple tensioning screw fixing plates 602 are all fixed on the hopper outlet flange 601, and each tensioning screw fixing plate 602 is detachably connected to the tensioning screw 8.

[0046] Specifically, the hopper outlet flange 601 serves as an interface between the hopper and the feed mechanism 4, connecting the two. The hopper outlet flange 601 is directly connected to the feed mechanism 4, and this connection can be achieved through mechanical connection methods such as welding and bolting. The tensioning screw fixing plate 602 is fixed to the hopper outlet flange 601, and each tensioning screw fixing plate 602 is provided with a corresponding hole for detachable connection with the tensioning screw 8. In this embodiment, each tensioning screw fixing plate 602 is detachably connected to the tensioning screw 8, thereby achieving rapid disassembly and assembly of the tensioning screw 8, which facilitates replacement of the stator and rotor assembly 5.

[0047] See also Figure 4 、 Figure 8 The discharge port assembly 7 may include: an outlet flange 701, multiple tensioning screw fixing parts 702 and a discharge port 704, wherein the outlet flange 701 is fixed to the end of the stator-rotor assembly 5; multiple tensioning screw fixing parts 702 are fixed to the outlet flange 701, each tensioning screw fixing part 702 is provided with a U-shaped groove 703, and the tensioning screw 8 is fitted in the U-shaped groove 703; the discharge port 704 is fixed to the end of the stator-rotor assembly 5.

[0048] In this embodiment, the outlet flange 701 serves as a connection point, firmly connecting the discharge port assembly 7 to the stator and rotor assembly 5. Each tensioning screw fixing portion 702 is provided with a U-shaped groove 703. This design allows the tensioning screw 8 to be easily inserted and adjusted in position. The U-shaped groove 703 provides a positioning and guiding function for the tensioning screw 8, allowing the tensioning screw 8 to move within a certain range, facilitating installation and adjusting the tension. The advantage of this arrangement is that it increases installation flexibility, simplifies the assembly process, and allows a certain degree of fine-tuning to achieve optimal connection strength.

[0049] After passing through the feed mechanism 4 and being processed by the stator-rotor assembly 5, the mortar ultimately reaches the discharge port assembly 7. Through the connection between the outlet flange 701 and the stator-rotor assembly 5, the mortar is guided to the discharge port 704. The tensioning screw 8 fits within the U-shaped groove 703. Tightening or loosening the screw adjusts the tightness of the entire assembly to ensure good stability. The mortar is discharged from the discharge port 704, completing the conveying process.

[0050] See also Figure 3 、 Figure 6 The tightening screw 8 may include: a long nut 801 and a T-shaped screw 802, wherein the long nut 801 is arranged between the two opposite tightening screw fixing plates 602, and a through hole is opened on the long nut 801; one end of the T-shaped screw 802 is threadedly engaged with the long nut 801, and the other end is engaged with the U-shaped groove 703; wherein, the mining screw stirring sprayer also includes: a plurality of wedge blocks 9, a plurality of wedge blocks 9 are engaged in the corresponding through holes, and the wedge blocks 9 pass through the corresponding tightening screw fixing plates 602.

[0051] Specifically, a through hole is provided on the long nut 801, which provides installation space for the wedge block 9. The long nut 801 serves as a threaded mating component of the T-screw 802, and the length of the entire connection structure can be adjusted by rotating the T-screw 802. The threaded end of the T-screw 802 is screwed into the long nut 801, and the tension is adjusted by rotation; the other end of the T-screw 802 is fitted into the U-shaped groove 703. The design of the U-shaped groove 703 allows the T-screw 802 to fit, thereby providing a certain degree of adjustment flexibility. The function of the wedge block 9 is to further enhance the stability of the connection and prevent the long nut 801 from rotating or shifting when subjected to external force. Through the wedge block 9, the tensioning force can be more effectively transmitted to the entire connection structure, thereby improving the overall stability.

[0052] See also Figure 9 A connecting block 10 is provided at one end of the feed shaft 401 close to the output end of the reducer 302, and a blind hole is opened on the connecting block 10, and the output end of the reducer 302 fits in the blind hole; the mining screw stirring sprayer also includes: a pin 11, which passes through the connecting block 10 and the output end of the reducer 302; wherein, a stator baffle 12 is provided at one end of the stator and rotor 502 away from the connecting block 10.

[0053] Among them, a blind hole is opened on the connecting block 10, which is used to match the output end of the reducer 302. The connecting block 10 serves as a connector between the feed shaft 401 and the output end of the reducer 302, ensuring the reliability and stability of power transmission. The output end of the reducer 302 is inserted into the blind hole on the connecting block 10. This plug-in connection method realizes simple and direct power transmission, can effectively transmit torque, and is easy to disassemble and maintain. The latch 11 passes through the connecting block 10 and the output end of the reducer 302, playing a fixing role, preventing the two from rotating relative to each other or separating during operation. When installing the latch 11, the corresponding holes are usually pre-designed on the connecting block 10 and the output end of the reducer 302, and then the latch 11 is inserted into the corresponding hole to lock the relative position of the two. The advantage of this design is that when maintenance or replacement of parts is required, the feed shaft 401 and the reducer 302 can be separated by simply pulling out the latch 11, which is easy to operate.

[0054] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
