[0028] Detailed Implementation

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] The mixing and premixing device of this utility model is described below with reference to the accompanying drawings.

[0031] like Figures 1 to 6As shown, this utility model provides a mixing and premixing device, which includes a feeding hopper 10 and a spraying mechanism 20. The feeding hopper 10 has a feeding port 11 at its upper end and a discharging port 12 at its lower end. The spraying mechanism 20 includes a spraying turntable 21, a rotating shaft 22 and a rotation drive 23. The rotating shaft 22 passes through the feeding hopper 10. The spraying turntable 21 is connected to the lower end of the rotating shaft 22 and is located inside the feeding hopper 10. The rotation drive 23 is driven to the rotating shaft 22 and is used to drive the rotating shaft 22 to rotate.

[0032] It should be noted that the mixing premixing device can be used in the mortar mixing equipment 200 to premix the mixing materials. The mixing materials include sand, cement and additives. The mortar mixing equipment 200 includes a mixing drum 201. The feed hopper 10 of the mixing premixing device is located on the mixing drum 201 and is connected to the mixing drum 201.

[0033] Specifically, the upper end of the feed hopper 10 is provided with a feed inlet 11 for feeding the mixed material, and the lower end of the feed hopper 10 is provided with a discharge outlet 12. The discharge outlet 12 is connected to the mixing drum 201 of the mortar mixing equipment 200. The upper end of the rotating shaft 22 passes through the feed hopper 10 and is driven by the rotation drive 23. The lower end of the rotating shaft 22 is connected to the spraying disc 21. The rotation drive 23 drives the rotating shaft 22 to rotate, so that the rotating shaft 22 drives the spraying disc 21 to rotate. The mixed material enters the feed hopper 10 from the feed inlet 11. The material falls into the hopper 10 and onto the spraying turntable 21. The rotation of the spraying turntable 21 causes the material to be premixed under centrifugal force and sprayed outside the spraying turntable 21. The premixed material falls into the mixing drum 201 from the discharge port 12, thereby stirring the premixed material. The mixing and premixing device of this utility model premixes the material by rotating the spraying turntable 21, which improves the mixing uniformity of the material, shortens the mixing time, and improves the mixing efficiency.

[0034] In this embodiment of the present invention, the mixing and premixing device further includes a feed guide plate 30 and a lifting drive assembly 40. The feed guide plate 30 is vertically disposed inside the feed hopper 10 and located above the spray turntable 21. The feed guide plate 30 is inclined in a direction away from the inner wall of the feed hopper 10 from top to bottom. The lifting drive assembly 40 is drivenly connected to the feed guide plate 30 and is used to drive the feed guide plate 30 to rise and fall.

[0035] like Figures 3 to 6As shown, the upper end of the feed guide plate 30 is vertically connected to the inner wall of the feed hopper 10, and the distance between the feed guide plate 30 and the inner wall of the feed hopper 10 gradually increases from top to bottom. The lifting drive assembly 40 is used to drive the feed guide plate 30 to move up and down in the feed hopper 10. When the mixed material is fed into the feed hopper 10 from the feed inlet 11, the mixed material can slide down onto the spray turntable 21 along the inclined direction of the feed guide plate 30, which plays the role of guiding the mixed material to slide down. The lifting drive assembly 40 drives the feed guide plate 30 to move up and down repeatedly, so that the feed guide plate 30 drives the falling mixed material to shake in the feed hopper 10 and disperse the falling mixed material, which further improves the mixing uniformity. The lifting movement of the feed guide plate 30 and the rotation movement of the spray turntable 21 cooperate with each other to realize the pre-mixing of the mixed material in the feed hopper 10, which greatly shortens the mixing time and improves the mixing efficiency.

[0036] In this embodiment of the utility model, the lifting drive assembly 40 includes a lifting transmission plate 41 and a swing push rod 42. The upper end of the lifting transmission plate 41 is connected to the feeding guide plate 30, and the lower end of the lifting transmission plate 41 has a transmission inclined edge 411. The transmission inclined edge 411 is inclined from top to bottom along the rotation direction of the spraying turntable 21. One end of the swing push rod 42 is connected to the spraying turntable 21, and the other end of the swing push rod 42 is used to abut against the transmission inclined edge 411 and push the lifting transmission plate 41 and the feeding guide plate 30 to rise along the transmission inclined edge 411.

[0037] like Figures 3 to 6 As shown, the rotating drive component 23 drives the spraying turntable 21 to rotate via the rotating shaft 22. The swing push rod 42 is mounted on the spraying turntable 21, allowing the spraying turntable 21 to drive the swing push rod 42 to swing around the rotating shaft 22 as the swing center. When the swing push rod 42 swings to the position corresponding to the lifting transmission plate 41, it first abuts against the upper end of the transmission inclined side 411. Then, the swing push rod 42 continues to swing along the inclination direction of the transmission inclined side 411 to push the lifting transmission plate 41 to move upward, thereby causing the lifting transmission plate 41 to drive the feeding guide plate 30 to rise. When the swing push rod 42 swings to the position corresponding to the lower end of the transmission inclined side 411... When the end abuts, the feed guide plate 30 rises to its limit position, and the swing push rod 42 continues to swing and moves away from the transmission inclined edge 411, causing the feed guide plate 30 to descend under the action of gravity. This realizes the reciprocating lifting and lowering of the feed guide plate 30. The lifting and lowering of the feed guide plate 30 causes the mixed material to shake and disperse, improving the mixing uniformity of the mixed material. Furthermore, the rotation drive 23 drives the spray turntable 21 to rotate, which in turn causes the spray turntable 21 to drive the swing push rod 42 to swing and push the feed guide plate 30 to rise. There is no need to add an additional lifting drive component. The structure and transmission are ingenious and reasonably designed, saving costs.

[0038] In this embodiment of the utility model, a vertically extending guide hole 412 is provided on the lifting transmission plate 41, and a guide rod 13 is provided on the inner wall of the feed hopper 10. The guide rod 13 is slidably disposed through the guide hole 412. Figures 3 to 6 As shown, the guide rod 13 extends from the inner wall of the feed hopper 10 toward the lifting transmission plate 41. The lifting transmission plate 41 has a guide hole 412 for the guide rod 13 to pass through. The guide hole 412 extends in the vertical direction, so that the guide rod 13 can cooperate with the guide hole 412 to guide the lifting transmission plate 41 to rise and fall, thereby improving the lifting stability and smoothness of the lifting transmission plate 41. In addition, the hole wall of the guide hole 412 can abut against the guide rod 13 when the feed guide plate 30 falls to its limit position under the action of gravity, thereby limiting the descent stroke of the lifting transmission plate 41. This makes it easier for the swing push rod 42 to swing to abut against the upper end of the transmission inclined edge 411 and reciprocate to push the lifting transmission plate 41 to rise.

[0039] Furthermore, a slider 31 is provided on the feed guide plate 30, and a vertically extending guide groove 14 is provided on the inner wall of the feed hopper 10, and the slider 31 is slidably disposed within the guide groove 14. Figures 3 to 6 As shown, a slider 31 is provided at the upper end of the feeding guide plate 30, and a guide groove 14 is provided on the inner wall of the feeding hopper 10. The guide groove 14 extends in the vertical direction. The slider 31 extends from the feeding guide plate 30 into the guide groove 14 and can slide along the guide groove 14. The slider 31 and the guide groove 14 slide together to guide the feeding guide plate 30 to rise and fall, which improves the stability and smoothness of the rising and falling of the feeding guide plate 30. In addition, the slider 31 can abut against the groove wall of the guide groove 14 when the feeding guide plate 30 falls to the limit position under the action of gravity, so as to limit the falling stroke of the feeding guide plate 30 and improve the reliability of the rising and falling.

[0040] In this embodiment of the utility model, the swing push rod 42 includes a connecting section 421 and a pushing section 422. The lower end of the connecting section 421 is connected to the spray turntable 21, and the pushing section 422 is connected to the upper end of the connecting section 421 and is bent from the connecting section 421 toward the inner wall of the feed hopper 10. The end of the pushing section 422 away from the connecting section 421 is used to abut against the transmission inclined edge 411.

[0041] like Figures 3 to 6As shown, the connecting section 421 extends vertically and is connected to the upper side of the spraying turntable 21. The pushing section 422 extends from the upper end of the connecting section 421 toward the inner wall of the feed hopper 10. The pushing section 422 is used to abut against the transmission inclined edge 411 to push the lifting transmission plate 41 and the feed guide plate 30 upward, so that the feed guide plate 30 drives the mixed material to shake and disperse the mixed material, improving the premixing effect. Furthermore, the pushing section 422 is arranged horizontally on the lifting transmission plate 41 and the connecting section 421. The connection section 421 increases the gap between the periphery of the spraying turntable 21 and the inner wall of the feed hopper 10, facilitating the falling of the mixed material thrown from the spraying turntable 21 to the discharge port 12, effectively preventing the mixed material from clogging. Furthermore, the connection section 421 is vertically positioned between the lifting transmission plate 41 and the spraying turntable 21, increasing the distance between the upper side of the spraying turntable 21 and the lower end of the feed guide plate 30, thus increasing the falling space for the mixed material and further preventing clogging.

[0042] In this embodiment of the invention, the feed guide plate 30 is arranged in a ring shape and surrounds a feed channel, the size of which gradually decreases from top to bottom. Figures 3 to 6 As shown, the feeding channel is used for the entry of the mixing material, and the size of the feeding channel gradually decreases from top to bottom, so that the mixing material falling along the feeding channel can fall onto the spraying turntable 21, effectively preventing the mixing material from falling directly from the outside of the spraying turntable 21 to the discharge port 12. The rotation of the spraying turntable 21 allows the mixing material to be pre-mixed under the action of centrifugal force, and the circumferentially arranged feeding guide plate 30 increases the contact area with the mixing material, which facilitates the shaking of the mixing material and fully disperses the mixing material, further improving the mixing uniformity.

[0043] Furthermore, such as Figure 4 As shown, there are two lifting transmission plates 41, which are respectively located on both sides of the annular feeding guide plate 30. There are also two swing push rods 42, which are respectively set to correspond one-to-one with the two lifting transmission plates 41. This allows any swing push rod 42 to push any lifting transmission plate 41 to rise, thereby driving the feeding guide plate 30 to rise, which increases the lifting frequency of the feeding guide plate 30 and further improves the premixing uniformity.

[0044] Those skilled in the art will understand that the number of lifting transmission plates 41 and the number of swing push rods 42 can also be set to three, four or other numbers. Multiple lifting transmission plates 41 are arranged at intervals along the outer periphery of the annular feeding guide plate 30, and multiple swing push rods 42 are arranged at intervals around the spray turntable 21, which further accelerates the shaking frequency of the feeding guide plate 30 and improves the premixing uniformity. The present invention does not limit the number of lifting transmission plates 41 and the number of swing push rods 42 in the mixing and premixing device.

[0045] In this embodiment of the invention, the feed hopper 10 has a premixing chamber 15 and a discharge chamber 16. The feed inlet 11 communicates with the premixing chamber 15, the spraying turntable 21 is disposed in the premixing chamber 15, the discharge outlet 12 communicates with the discharge chamber 16, and the size of the discharge chamber 16 gradually decreases from top to bottom. Figure 3 , Figure 4 and Figure 7 As shown, the premixing chamber 15 is located above and communicates with the discharge chamber 16. The spraying turntable 21 is located inside the premixing chamber 15 to premix the materials by rotating and to throw the materials out of the spraying turntable 21. The materials thrown out from the spraying turntable 21 fall into the discharge chamber 16 and then fall from the discharge port 12 into the mixing drum 201, thereby stirring the premixed materials. The stirring time is short and the efficiency is high. In addition, the size of the discharge chamber 16 gradually decreases from top to bottom to guide the materials to slide down, which improves the smoothness of the discharge.

[0046] In this embodiment of the utility model, the upper end of the feeding hopper 10 is provided with a feeding cylinder 17, which is connected to the feeding port 11. The number of feeding cylinders 17 is set to multiple, and the multiple feeding cylinders 17 are arranged circumferentially at intervals to form an installation space 171. The rotation drive component 23 is provided in the installation space 171. The number of feeding ports 11 is the same as the number of feeding cylinders 17 and they are connected in a one-to-one correspondence.

[0047] like Figure 2 , Figure 4 and Figure 7 As shown, there are two feed cylinders 17, which are spaced apart on the feed hopper 10, and an installation space 171 is formed between the two feed cylinders 17. The rotating drive component 23 is located above the feed hopper 10 and within the installation space 171. The two feed cylinders 17 are located on both sides of the installation space 171 to protect the rotating drive component 23, effectively preventing the mixed material from entering the installation space 171 and causing dust to enter the interior of the rotating drive component 23, thus extending the service life of the rotating drive component 23. Each feed cylinder 17 is connected to a corresponding feed port 11 and is arranged around the periphery of the corresponding feed port 11, so that each feed cylinder 17 plays the role of guiding the mixed material to feed, further preventing the mixed material from splashing.

[0048] Those skilled in the art will understand that the number of feed cylinders 17 can also be set to three, four or other numbers. Multiple feed cylinders 17 are arranged circumferentially on the feed hopper 10, and the installation space 171 is located between multiple feed cylinders 17 to prevent the mixed material from entering the installation space 171 and causing dust to enter the interior of the rotating drive component 23. Each feed cylinder 17 can also play the role of guiding the feeding and preventing the mixed material from splashing. The number of feed cylinders 17 in the mixing and premixing device of this utility model is not limited.

[0049] Furthermore, this utility model also provides a mortar mixing device 200, which includes the mixing and premixing device described above. The mortar mixing device 200 also includes a mixing drum 201. The feed hopper 10 of the mixing and premixing device is disposed on the mixing drum 201, and the discharge port 12 at the lower end of the feed hopper 10 is connected to the inner cavity of the mixing drum 201, so that the premixed material can fall from the discharge port 12 into the mixing drum 201 for mixing. The specific structure of the mixing and premixing device is as described in the above embodiments. Since the mortar mixing device 200 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
