[0021] The present invention provides an environmentally friendly dry-mix mortar mixer through improvement, which has the following improvements and advantages compared with the prior art:

[0022] First, the present invention is provided with a heat exchange mechanism. When the stirring motor is running, a large amount of heat will be generated. Then the heat dissipation fan can be started. The heat dissipation fan generates suction inside the motor cover, and the outside air will enter the inside of the motor cover through the air inlet. At the same time, water is sent to the inside of the heat exchange tube through the water inlet pipe. At this time, the heat generated by the stirring motor can be transferred to the heat exchange tube and the water inside the heat exchange tube. When the outside air enters the inside of the heat exchange tube through the air inlet, it will first contact the heat exchange tube. The outside air can take away the heat on the heat exchange tube and move upward. The water in the heat exchange tube moves to the inside of the heating tube, and the air with heat contacts the heating tube. The heating tube absorbs the heat again and stores it in the water. The heated water can be discharged through the outlet pipe. The water discharged from the outlet pipe can be added to the raw materials when the mortar raw materials are mixed. The water with heat can improve the hydration efficiency of the cement in the raw materials, thereby improving the uniformity of the mortar mixing. While achieving the heat dissipation of the motor, the heat can also be converted to preheat the water, reducing the energy consumption required for subsequent water heating, thereby achieving the effect of environmental protection and energy saving.

[0023] Second: In the present invention, since a driving gear is installed at the bottom of the rotating shaft, the rotor of the stirring motor is unbalanced in the up and down directions, and the stirring motor will generate up and down vibrations when it is running. When the stirring motor drives the piston plate to move inside the sealing seat through the rotating shaft, due to the setting of the check valve, when the stirring motor generates upward vibrations, the piston plate moves upward so that the outside air can quickly enter the inside of the sealing seat. When the stirring motor generates downward vibrations, the air inside the sealing seat cannot be quickly discharged from the inside of the sealing seat, so that the piston plate will generate greater resistance when moving inside the sealing seat, which can have a shock-absorbing effect on the stirring motor. At the same time, the stirring motor can increase the contact area with the heat exchange tube when moving, thereby improving the heat dissipation effect of the stirring motor.

[0024] Third: The present invention can start the adjusting motor through the setting of the adjusting mechanism, and the adjusting motor drives the transmission shaft to rotate, and the transmission shaft and the transmission ring are movably connected through a reciprocating thread, so that the rotation of the transmission shaft will cause the transmission ring to move up and down in a small range inside the water distribution pipe, and the transmission ring and the nozzle are movably connected through a connecting block and a connecting shaft. The up and down movement of the transmission ring can drive the nozzle to swing up and down on the water distribution pipe, thereby changing the angle of water injection of the nozzle, increasing the range of water injection of the nozzle, and thus improving the uniformity of contact between water and mortar.

[0025] Fourthly, in the present invention, since the first stirring shaft and the second stirring shaft are transmitted through the transmission gear and the transmission belt, the first stirring shaft and the second stirring shaft rotate in the same direction, and thus when the first stirring shaft and the second stirring shaft drive the stirring rod and the stirring blade to rotate, the piston plate and the stirring blade on the first stirring shaft and the stirring rod and the stirring blade on the second stirring shaft will generate shear force when they are staggered with each other, and then the larger raw materials agglomerated in the mortar can be crushed, thereby further improving the uniformity of the mortar after mixing;

[0026] Fifth: In the present invention, the transmission shaft can drive the transmission gear ring to rotate through the driving gear, and the transmission gear ring further drives the push plate to rotate. Since the push plate is a triangular structure, the push plate moves on the inner wall of the fuselage and can push the raw materials around the inside of the fuselage to the middle position inside the fuselage, so that the raw materials around the inside of the fuselage can also be evenly mixed.

[0038] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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.

[0039] The present invention provides an environmentally friendly dry-mix mortar mixer through improvement. The technical solution of the present invention is:

[0040] like Figures 1 to 3As shown, an embodiment of the present invention provides an environmentally friendly dry-mix mortar mixer, including a body 1 and a stirring motor 7 installed on the top of the body 1, a feed port 2 is opened on the body 1, the feed port 2 is an opening of a rectangular structure, the feed port 2 is communicated with the interior of the body 1, a feed hopper 3 is fixedly installed at a position corresponding to the feed port 2 on the body 1, the feed hopper 3 is convenient for putting the mortar raw materials into the interior of the body 1 through the feed port 2, a first stirring shaft 5 and a second stirring shaft 6 are movably installed inside the body 1, one end of the first stirring shaft 5 and the second stirring shaft 6 both penetrate the top wall of the body 1 upward, a transmission mechanism is arranged on the top of the body 1, the transmission mechanism includes a rotating shaft 8, a driving gear 9, a driven gear 10, a transmission gear 11 and a transmission belt 12, the rotating shaft 8 is a cylindrical structure, the rotating shaft 8 is fixedly installed on the output end of the stirring motor 7, the driving gear 9 is fixedly welded on the rotating shaft 8, the driven gear 10 is fixedly welded on the first stirring shaft 5, and the driving gear 9 and the driven gear 10 are fixedly welded on the first stirring shaft 5, and the driving gear 9 and the driven gear 10 are fixedly welded on the first stirring shaft 5. The driven gears 10 are meshed for transmission. There are two transmission gears 11. The two transmission gears 11 are fixedly welded on the first stirring shaft 5 and the second stirring shaft 6 respectively. The transmission belt 12 is sleeved between the two transmission gears 11. The transmission belt 12 and the two transmission gears 11 are meshed for transmission. The stirring motor 7 is started. The stirring motor 7 drives the driving gear 9 to rotate, and the driving gear 9 then drives the driven gear 10 to rotate. While the driven gear 10 drives the first stirring shaft 5 to rotate, it can also drive the second stirring shaft 6 to rotate through the transmission gear 11 and the transmission belt 12. Since the diameter difference between the driving gear 9 and the driven gear 10 is large, the energy required by the stirring motor 7 to drive the driven gear 10 through the driving gear 9 will also become smaller, thereby reducing the energy consumption of the stirring motor 7 during operation. At the same time, the first stirring shaft 5 and the second stirring shaft 6 rotate simultaneously to mix and stir the raw materials inside the fuselage 1, which can improve the stirring efficiency of the first stirring shaft 5 and the second stirring shaft 6.

[0041] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, a motor cover 13 is arranged on the outside of the stirring motor 7, and the motor cover 13 is a hollow structure. The stirring motor 7 is located inside the motor cover 13, and the motor cover 13 is fixedly installed on the top of the fuselage 1. A heat exchange mechanism is arranged inside the motor cover 13, and the heat exchange mechanism includes a heat dissipation fan 15, a heat exchange pipe 16, a water inlet pipe 17, a heating pipe 18 and a water outlet pipe 19. The heat dissipation fan 15 is fixedly installed on the top of the motor cover 13, and an air outlet 14 is opened between the motor cover 13 and the heat dissipation fan 15. The air outlet 14 is a circular opening. A plurality of air inlets 20 are opened on the outer wall of the motor cover 13, and the air inlet 20 is a rectangular groove. The heat dissipation is started The fan 15 can extract the air inside the motor cover 13 through the air outlet 14, and the outside air can enter the inside of the motor cover 13, and then be discharged through the heat dissipation fan 15. The heat exchange tube 16 is a spiral tubular structure. The heat exchange tube 16 is movably sleeved on the stirring motor 7. The heat exchange tube 16 fits the side wall of the stirring motor 7. The water inlet pipe 17 is a cylindrical tube. The water inlet pipe 17 is embedded and installed below the side wall of the motor cover 13. One end of the water inlet pipe 17 is fixed and connected to the bottom of the heat exchange tube 16, and the other end of the water inlet pipe 17 is connected to the external water source. The heating tube 18 is a volute tubular structure. The heating tube 18 is arranged on the motor cover 13. At the top of the hood 13, one end of the heating tube 18 is fixed and connected to the top of the heat exchange tube 16. The water outlet pipe 19 is a tubular structure. The water outlet pipe 19 is fixed and connected to one end of the heating tube 18. Through the setting of the heat exchange mechanism, when the stirring motor 7 is running, a large amount of heat will be generated. Then the heat dissipation fan 15 can be started. The heat dissipation fan 15 generates suction inside the motor hood 13, and the outside air will enter the inside of the motor hood 13 through the air inlet 20. At the same time, water is delivered to the inside of the heat exchange tube 16 through the water inlet pipe 17. At this time, the heat generated by the operation of the stirring motor 7 can be transferred to the heat exchange tube 16 and the water inside the heat exchange tube 16. When the outside air enters the heat exchange tube 16 through the air inlet 20, it will first contact the heat exchange tube 16. The outside air can take away the heat on the heat exchange tube 16 and move upward. At this time, the water in the heat exchange tube 16 can move to the inside of the heating tube 18. The air with heat contacts the heating tube 18. The heating tube 18 can absorb the heat again and store it in the water. Then the heated water can be discharged through the water outlet pipe 19. The water discharged from the water outlet pipe 19 can be added to the raw materials when the mortar raw materials are mixed. The water with heat can improve the hydration efficiency of the cement in the raw materials, thereby improving the uniformity of the mortar mixing.

[0042] A torsion spring shaft 21 is movably installed on the upper part of the interior of the air inlet 20. The torsion spring shaft 21 is a cylindrical structure. A movable plate 22 is fixedly sleeved on the torsion spring shaft 21. The movable plate 22 is a rectangular structure. When the heat dissipation fan 15 is started, the movable plate 22 will flip inside the air inlet 20. At this time, the movable plate 22 will become inclined. The outside air will be directly blown onto the surface of the heat exchange tube 16 after being guided by the movable plate 22, thereby improving the heat exchange efficiency of the heat exchange tube 16. At the same time, when the stirring motor 7 and the heat dissipation fan 15 are not in use, the movable plate 22 will seal the interior of the air inlet 20 to prevent the external environment from affecting the stirring motor 7. An air guide block 23 is fixedly installed on the upper part of the motor cover 13. The air guide block 23 is a hollow annular structure with a gradually smaller interior, and the air guide block 23 can guide the hot air moving upward.

[0043] A water distribution pipe 24 is arranged above the interior of the fuselage 1. The water distribution pipe 24 is an annular pipe. A plurality of nozzles 25 are evenly distributed and movably mounted on the water distribution pipe 24. The nozzles 25 are tubular structures with a spherical end. The nozzles 25 can swing on the water distribution pipe 24. A connecting pipe 26 is fixedly installed at the top of the water distribution pipe 24. The connecting pipe 26 is connected to the inside of the water distribution pipe 24. The bottom of the water outlet pipe 19 is fixedly connected to the connecting pipe 26 and is connected to each other. The water with heat can be discharged from the water distribution pipe 24 through the connecting pipe 26. The inside of the pipe 24 can then be sprayed into the inside of the fuselage 1 through the nozzle 25 to mix with the raw materials. The water outlet pipe 19 is sleeved with an insulation sleeve 27, which is made of insulation material. The insulation sleeve 27 can reduce the heat loss of the water inside the water outlet pipe 19 during transportation. A heater 28 is arranged at the bottom of the water outlet pipe 19. The heater 28 can be driven by an external power supply, and then the water inside the water outlet pipe 19 can be heated for the second time, so that the temperature of the water entering the water distribution pipe 24 is higher, so as to meet different mixing requirements.

[0044] like Figure 2 and Figure 6As shown, a sealing seat 29 is fixedly installed on the upper part of the interior of the fuselage 1. The sealing seat 29 is a hollow cylindrical structure. The bottom of the rotating shaft 8 passes through the side wall of the sealing seat 29 and is located inside the sealing seat 29. A piston plate 30 is movably connected to the bottom of the rotating shaft 8. The piston plate 30 is a circular plate with the same size as the inside of the sealing seat 29. A check valve 31 is inlaid and installed at the bottom of the piston plate 30. The check valve 31 allows the outside air to quickly enter the inside of the sealing seat 29, while the air inside the sealing seat 29 can only leave the inside of the sealing seat 29 at a very slow speed. A movable groove 32 is opened at the position corresponding to the driving gear 9 on the fuselage 1. The driving gear 9 is located inside the movable groove 32. Since the driving gear 9 is installed at the bottom of the rotating shaft 8, the rotation of the stirring motor 7 is There is an imbalance in the up and down directions, and the stirring motor 7 will generate up and down vibrations when it is running. When the stirring motor 7 drives the piston plate 30 to move inside the sealing seat 29 through the rotating shaft 8, due to the setting of the check valve 31, when the stirring motor 7 generates upward vibrations, the piston plate 30 moves upward so that the outside air can quickly enter the inside of the sealing seat 29. When the stirring motor 7 generates downward vibrations, the air inside the sealing seat 29 cannot be quickly discharged from the inside of the sealing seat 29, so that the piston plate 30 will generate greater resistance when moving inside the sealing seat 29, which can have a shock-absorbing effect on the stirring motor 7. At the same time, the stirring motor 7 can increase the contact area with the heat exchange tube 16 when moving, thereby improving the heat dissipation effect of the stirring motor 7.

[0045] like Figure 2 , Figure 7 as well as Figure 8As shown, a mounting ring 38 is fixedly installed on the top of the fuselage 1, and an adjusting mechanism is arranged at a position corresponding to the water distribution pipe 24 on the fuselage 1, and the adjusting mechanism includes an adjusting motor 33, a transmission shaft 34, a transmission ring 35, a connecting block 36 and a connecting shaft 37.

The nozzle 25 and the transmission ring 35 are movably connected through the connecting block 36 and the connecting shaft 37. When water is injected into the interior of the fuselage 1 through the nozzle 25, the adjusting motor 33 can be started through the setting of the adjusting mechanism. The adjusting motor 33 drives the transmission shaft 34 to rotate, and the transmission shaft 34 and the transmission ring 35 are movably connected through a reciprocating thread, so that the rotation of the transmission shaft 34 will cause the transmission ring 35 to move up and down in a small range inside the water distribution pipe 24, and the transmission ring 35 and the nozzle 25 are movably connected through the connecting block 36 and the connecting shaft 37. The up and down movement of the transmission ring 35 can drive the nozzle 25 to swing up and down on the water distribution pipe 24, thereby changing the angle of water injection of the nozzle 25, increasing the range of water injection of the nozzle 25, and thus improving the uniformity of contact between water and mortar.

[0046] Four groups of stirring rods 39 are evenly distributed and fixedly installed on the first stirring shaft 5 and the second stirring shaft 6. A stirring blade 40 is fixedly installed on one end of the plurality of stirring rods 39 away from the first stirring shaft 5 and the second stirring shaft 6. The stirring blade 40 is a trapezoidal block, and the stirring blade 40 is tilted. Since the first stirring shaft 5 and the second stirring shaft 6 are transmitted through the transmission gear 11 and the transmission belt 12, the first stirring shaft 5 and the second stirring shaft 6 rotate in the same direction, so that when the first stirring shaft 5 and the second stirring shaft 6 drive the stirring rods 39 and the stirring blade 40 to rotate, the piston plate 30 and the stirring blade 40 on the first stirring shaft 5 and the stirring rods 39 and the stirring blade 40 on the second stirring shaft 6 will generate shear force when they are staggered with each other, so that the larger raw materials agglomerated in the mortar can be crushed, thereby further improving the uniformity of the mortar after mixing;

[0047] A plurality of push plates 41 are arranged inside the fuselage 1. The push plates 41 are triangular plates, which fit against the inner wall of the fuselage 1. A transmission gear ring 43 is movably installed inside the fuselage 1 at a position corresponding to the push plates 41. The transmission gear ring 43 is a ring structure. The push plates 41 are fixedly connected to the transmission gear ring 43. A driving gear 42 is fixedly installed at the bottom of the transmission shaft 34 at a position corresponding to the transmission gear ring 43. The driving gear 42 is meshed with the transmission gear ring 43 for transmission, so that the transmission shaft 34 can drive the transmission gear ring 43 to rotate through the driving gear 42, and the transmission gear ring 43 further drives the push plates 41 to rotate. Since the push plates 41 are of a triangular structure, the push plates 41 can move on the inner wall of the fuselage 1 to push the raw materials around the inside of the fuselage 1 to the middle position inside the fuselage 1, so that the raw materials around the inside of the fuselage 1 can also be evenly mixed.

[0048] A sealing plate 44 is movably installed inside the feed hopper 3, and the sealing plate 44 can seal the inside of the feed hopper 3 to prevent dust from escaping to the outside through the feed hopper 3 when the raw materials are mixed. A discharge plate 45 is arranged at the lower part of the interior of the fuselage 1, and the discharge plate 45 seals between the fuselage 1 and the discharge pipe 4. A cylinder 46 is installed at the bottom of the discharge pipe 4, and the output end of the cylinder 46 is connected to the discharge plate 45. When the raw material mixing is completed, the cylinder 46 can be started, and the cylinder 46 drives the discharge plate 45 to move upward. At this time, the raw materials inside the fuselage 1 can be moved to the inside of the discharge pipe 4 through the bottom of the fuselage 1, and then discharged to the outside through the discharge pipe 4. A plurality of support legs 47 are fixedly installed at the bottom of the fuselage 1, and the support legs 47 are used to support the fuselage 1 at a certain height.

[0049] Specific implementation steps: start the stirring motor 7, the stirring motor 7 drives the driving gear 9 to rotate, the driving gear 9 then drives the driven gear 10 to rotate, the driven gear 10 drives the first stirring shaft 5 to rotate, and at the same time, it can also drive the second stirring shaft 6 to rotate through the transmission gear 11 and the transmission belt 12. Since the diameter difference between the driving gear 9 and the driven gear 10 is relatively large, the energy required by the stirring motor 7 to drive the driven gear 10 through the driving gear 9 will also be reduced, thereby reducing the energy consumption of the stirring motor 7 during operation. At the same time, the first stirring shaft 5 and the second stirring shaft 6 rotate simultaneously to mix and stir the raw materials inside the fuselage 1, which can improve the stirring efficiency of the first stirring shaft 5 and the second stirring shaft 6;

[0050] At the same time, by providing a heat exchange mechanism, a large amount of heat will be generated when the stirring motor 7 is running, and then the heat dissipation fan 15 can be started. The heat dissipation fan 15 generates suction inside the motor cover 13, and the outside air will enter the inside of the motor cover 13 through the air inlet 20. At the same time, water is sent to the inside of the heat exchange tube 16 through the water inlet pipe 17. At this time, the heat generated by the operation of the stirring motor 7 can be transferred to the heat exchange tube 16 and the water inside the heat exchange tube 16. When the outside air enters the inside of the heat exchange tube 16 through the air inlet 20, it will first contact the heat exchange tube 16. The outside air can contact the heat exchange tube 16 to transfer the heat on the heat exchange tube 16. The amount is taken away and moves upward. At this time, the water in the heat exchange tube 16 can move to the inside of the heating tube 18. The air with heat contacts the heating tube 18, and the heating tube 18 can absorb the heat again and store it in the water. Then the heated water can be discharged through the outlet pipe 19. The water discharged from the outlet pipe 19 can be added to the raw materials when the mortar raw materials are mixed. The water with heat can improve the hydration efficiency of the cement in the raw materials, thereby improving the uniformity of the mortar mixing. While achieving the heat dissipation of the motor, the heat can also be converted to preheat the water, reducing the energy consumption required for subsequent water heating, thereby achieving the effect of environmental protection and energy saving.
