This invention relates to the field of material mixing equipment technology, and discloses a material mixer including a main box. The upper inner part of the main box has a sand washing chamber for washing the sandy aggregate raw materials used in mortar concrete processing. The lower inner part of the main box is divided into a mixing chamber and a sedimentation chamber from top to bottom by a partition. These chambers are used for mixing materials during mortar concrete processing and for collecting and settling the sand washing water generated in the sand washing chamber.

The lower side of one side of the base is connected to the bottom of the main box through a support frame.

[0021] Working Principle: When mixing mortar and concrete for road and bridge construction projects, the sandy aggregate raw materials used in the mortar and concrete must first be cleaned. At this time, workers put the required sandy aggregate raw materials into the washing chamber inside the main box and add an appropriate amount of washing water. Simultaneously, the sandy aggregate washing mechanism is activated, and the drive motor drives the upper drive shaft to rotate. The rotation of the upper drive shaft drives the agitator plate within the washing chamber to rotate. The rotation of the agitator plate agitates the sandy aggregate and washing water within the washing chamber, thereby removing the soil and stone powder from the sandy aggregate. After impurities are separated and the sand aggregate in the washing chamber is cleaned and the washing wastewater is discharged, the operator can pull the insert plate out of the slot of the mesh plate through the handle groove on the insert plate. This allows the cleaned sand aggregate to fall through the mesh of the mesh plate into the mixing chamber. At the same time, the vibrating motor on the main box vibrates synchronously, accelerating the speed at which the cleaned sand aggregate enters the mixing chamber, thus facilitating subsequent material mixing operations. After the sand aggregate in the washing chamber is cleaned, the wastewater circulation and sedimentation mechanism is activated. The operator opens the automatic filter valve on the conveying pipe to allow the wastewater in the washing chamber to flow freely. The cleaning wastewater enters the sedimentation chamber through a conveying pipe for sedimentation. Simultaneously, the raw material mixing and conveying mechanism is activated. Workers add the cement and reinforcing agent materials required for mortar concrete processing into the mixing chamber through the inlet pipe. The shaft of drive motor two drives the lower drive shaft one to rotate synchronously. Simultaneously, the rotation of the lower drive shaft one drives the winch on it to rotate synchronously. Through the rotation of the winch in the mixing chamber, the cleaned sand aggregate, cement, and reinforcing agent materials are mixed and conveyed. Finally, the uniformly mixed material is fed into the mixing tank through the outlet pipe, thus completing the mortar concrete processing. The mixing and conveying of various materials: At the same time as the raw material mixing and conveying mechanism is started, the dust breathing and filtering mechanism is started. While the various materials in the mixing chamber are mixed and conveyed by the winch, the dust generated by the mixing of various powder materials in the mixing chamber is carried by the air and enters the dust collection box through the breathing pipe. The dust carried by the air enters the dust collection box, thereby squeezing the air in the dust collection box and discharging it into the external environment through the pressure relief pipe. When the air in the dust collection box is discharged through the pressure relief pipe, it is filtered by the filter seat on it to prevent the dust overflowing from the dust collection box from polluting the surrounding environment.After the raw material mixing and conveying mechanism mixes all the materials required for mortar concrete evenly and inputs them into the mixing drum, the material filtering and mixing mechanism is activated. At this time, the raw material mixing and conveying mechanism conveys the evenly mixed material to the screen plate of the mixing drum through the discharge pipe. Then, the drive motor three in the base operates, and the rotating shaft of the drive motor three drives the drive shaft two in the mixing drum to rotate synchronously. While the drive shaft two rotates, it drives the mixing blade and the mounting seat three to rotate. While the mounting seat three rotates, it drives the spherical protrusion on it to rotate. The rotation of the spherical protrusion on the mounting seat three causes the mounting seat two in the inner cavity to repeatedly move up and down radially. Through the support spring on the mounting seat two and the mounting seat three at its bottom, the up and down radial movement causes the connecting column and the screen plate to vibrate synchronously up and down, thereby vibrating the mixed material on the screen plate. This causes the mixed material on the screen plate to fall into the middle and lower part of the mixing drum through the screen holes on the screen plate. After the mixed materials are sieved, when they reach the lower part of the mixing tank, the pump draws the upper layer of washing wastewater from the sedimentation chamber through a connecting pipe and injects it back into the upper part of the mixing tank. As the liquid level in the sedimentation chamber decreases, the floating plate in the sedimentation chamber descends synchronously, driving the floating joint and connecting pipe to descend synchronously until the bottom of the floating plate contacts the sediment layer at the bottom of the sedimentation chamber, thus reusing the washing and sedimentation wastewater. When both the sieved mixed materials and the sedimented washing wastewater reach the lower part of the mixing tank, the drive shaft rotates, driving the mixing blades on it to rotate synchronously, thus mixing the materials into mortar concrete. After mixing is complete, the operator can open the control valve on the discharge pipe to discharge the mixed mortar concrete from the mixing tank for use.

[0022] This invention provides a material mixer. It has the following beneficial effects:

[0023] 1. This invention increases and enriches the functionality of the material mixing equipment by adding a sand aggregate washing mechanism to the material mixing equipment. As a result, only a single piece of equipment is needed to complete the processing of mortar and concrete in road and bridge construction projects. Furthermore, the auxiliary equipment of sand washing equipment is no longer required during the mortar and concrete processing process. This reduces the number of equipment required for mortar and concrete processing in road and bridge construction and also reduces the equipment investment cost in the early stage of construction projects.

[0024] 2. This invention filters and settles the washing wastewater after the sand washing process is completed, and then uses it in the mixing and processing of mortar and concrete. This fully utilizes the water resources used in the process, improves the water resource utilization rate, and reduces the waste of water resources in road and bridge construction projects.

[0025] 3. This invention adds a breathing tube and a matching dust-raising and filtering mechanism to the mixing chamber to collect the dust generated during the mixing process of various dry powder materials, thereby preventing the dust from overflowing and polluting the surrounding environment.

[0026] 4. This invention divides the mixing tank into layers. The upper layer is used for sieving the mixed materials to prevent large impurities in the mixed materials from affecting the normal use of the mortar and concrete in subsequent processing. The lower layer is used for mixing the mixed materials and water. The repeated up-and-down radial jumping generated by the various spherical protrusions on it can achieve a multi-directional mixing effect in the mixing tank, resulting in higher mixing uniformity. On the other hand, the vibration transmitted by it can also reduce the amount of material adhering to the mixing blades and reduce the loss of materials during the mixing process.

Detailed Implementation

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example:

[0039] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a material mixer, comprising:

[0040] The main box 1 has a sand washing chamber 17 in the upper middle part of its inner side, which is used to wash the sandy aggregate raw materials used in the mortar concrete processing. The lower middle part of its inner side is divided into a mixing chamber 28 and a sedimentation chamber 31 from top to bottom by a partition 27, which are used to mix the materials in the mortar concrete processing process and to collect and settle the sand washing water generated in the sand washing chamber 17.

[0041] The mixing tank 14 is located on one side of the main box 1 and is used to screen and mix the mixed materials conveyed from the mixing chamber 28.

[0042] The sand aggregate washing mechanism is located inside the sand washing chamber 17 and is used to wash and remove the mud and stone powder impurities contained in the sand aggregate.

[0043] Please see the appendix Figure 4The sand aggregate washing mechanism also includes a drive shaft 25. The drive shaft 25 is rotatably connected to the inner middle of the sand washing chamber 17 and the mixing chamber 28. Multiple stirring blades 16 are fixedly connected at equal intervals on the outer wall of the upper drive shaft 25. A drive motor 6 is provided in the middle and upper part of one side of the main box 1, and the output end of the drive motor 6 passes through the main box 1 and is connected to one end of the upper drive shaft 25.

[0044] When the sand aggregate washing mechanism is started, the staff put the required sand aggregate raw materials into the washing chamber 17 in the main box 1, and add an appropriate amount of washing water into the washing chamber 17. Then, the drive motor 6 drives the upper drive shaft 25 to rotate. While the upper drive shaft 25 rotates, it drives the stirring plate 16 on it to rotate in the washing chamber 17. While the stirring plate 16 rotates in the washing chamber 17, it drives the sand aggregate and washing water in the washing chamber 17 to turn over, thereby separating the impurities such as mud and stone powder in the sand aggregate.

[0045] Please see the appendix Figure 5 The sand aggregate washing mechanism includes a perforated plate 24, which is fixedly connected to the upper inner part of the main box 1. A slot 32 is provided in the middle of the perforated plate 24. A slot 18 is provided in the upper rear part of the main box 1, and the slot 18 communicates with the interior of the slot 32. A plate 20 is slidably connected inside the slot 18, and the end of the plate 20 passes through the slot 18 and extends into the slot 32. Two handle slots 34 are provided at equal intervals near the edge on one side of the middle part of the plate 20. A fixing slot 33 is provided on one side of the top of the plate 20. A spring pin seat 19 is provided in the upper rear part of the main box 1. Vibration motors 4 are provided on both sides of the upper front part of the main box 1.

[0046] After the sand aggregate in the sand washing chamber 17 has been washed and the washing wastewater has been discharged, the workers can pull the insert plate 20 out of the insertion slot 32 of the mesh plate 24 through the handle groove 34 on the insert plate 20. This allows the sand aggregate after washing in the sand washing chamber 17 to fall into the mixing chamber 28 through the mesh on the mesh plate 24. At the same time, the vibration motor 4 on the main box 1 will vibrate synchronously to accelerate the speed at which the sand aggregate after washing on the mesh plate 24 enters the mixing chamber 28, thereby facilitating the subsequent material mixing operation.

[0047] Adding a fixing groove 33 and a spring pin seat 19 to the insert plate 20 and the main box 1 respectively is to ensure the sealing of the mesh plate 24 by the insert plate 20 when it is inserted for use later. This prevents the washing water in the sand washing chamber 17 from entering the mixing chamber 28, and also prevents unwashed sand aggregate from entering the mixing chamber 28, thus affecting the normal use of the mortar concrete produced later.

[0048] The raw material mixing and conveying mechanism is set inside the mixing chamber 28 and is used to mix and convey various materials required for mortar and concrete processing to the mixing tank 14 for stirring and mixing.

[0049] The raw material mixing and conveying mechanism includes a discharge pipe 15. One end of the discharge pipe 15 is connected to the lower middle part of one side of the mixing chamber 28, and the other end of the discharge pipe 15 is connected to the upper middle part of one side of the mixing barrel 14. A winch 26 is provided on the lower drive shaft 25. A drive motor 7 is provided in the middle of the side of the main box 1 away from the mixing barrel 14. The output end of the drive motor 7 passes through the main box 1 and is connected to one end of the lower drive shaft 25. An inlet pipe 5 is provided on the middle side of the front and rear ends of the main box 1 near the edge. The inside of the inlet pipe 5 is connected to the inside of the mixing chamber 28. A sealing cover is provided on the end of the inlet pipe 5 away from the main box 1.

[0050] When the raw material mixing and conveying mechanism is started, the workers add the cement and reinforcing agent materials required for mortar and concrete processing into the mixing chamber 28 through the feed pipe 5. The shaft of the drive motor 7 drives the lower drive shaft 25 to rotate synchronously. At the same time, the lower drive shaft 25 drives the winch 26 on it to rotate synchronously. Through the rotation of the winch 26 in the mixing chamber 28, the sand aggregate, cement and reinforcing agent materials that have been cleaned in the mixing chamber 28 are mixed and conveyed. Finally, the uniformly mixed materials are fed into the mixing tank 14 through the discharge pipe 15, thus completing the mixing and conveying operation of various materials for mortar and concrete.

[0051] The dust breathing filter mechanism is located in the lower middle part of one side of the main box 1 and is used to collect the dust generated during the mixing of materials in the mixing chamber 28.

[0052] The dust collection box 10 includes a dust collection box 10. One side of the dust collection box 10 is fixedly connected to the lower front part of the main box 1. The top two sides of the dust collection box 10 are respectively connected to one end of the breathing pipe 2 on the same side. The other end of the breathing pipe 2 is respectively connected to the upper middle two sides of the mixing chamber 28. A pressure relief pipe 9 is provided on one side of the middle part of the top of the dust collection box 10, and the inside of the pressure relief pipe 9 is connected to the inside of the dust collection box 10. A filter seat 8 is threadedly connected to the end of the pressure relief pipe 9 away from the dust collection box 10.

[0053] At the same time as the raw material mixing and conveying mechanism is started, the dust breathing and filtering mechanism is also started. While the various materials in the mixing chamber 28 are mixed and conveyed by the winch 26, the dust generated by the mixing of various powder materials in the mixing chamber 28 is carried by the air and enters the dust collection box 10 through the breathing pipe 2. The dust carried by the air enters the dust collection box 10, thereby squeezing the air in the dust collection box 10 and discharging it into the external environment through the pressure relief pipe 9. When the air in the dust collection box 10 is discharged through the pressure relief pipe 9, it is filtered by the filter seat 8 on it, thereby preventing the dust overflowing from the dust collection box 10 from polluting the surrounding environment.

[0054] After the workers inject the various materials required for mortar and concrete into the mixing chamber 28 through the feed pipe 5, they can then seal the feed pipe 5 with the sealing cover to prevent dust from overflowing from the mixing chamber 28 during the mixing process and thus polluting the surrounding environment.

[0055] The wastewater circulation sedimentation mechanism is installed inside the sedimentation chamber 31 to settle the sand washing wastewater generated in the sand washing chamber 17 and reuse it.

[0056] The wastewater circulation sedimentation mechanism includes a pump 23. The pump 23 is fixedly connected to one side of the lower rear part of the main tank 1. A floating plate 30 is installed inside the sedimentation chamber 31. A floating joint 29 is installed in the middle of the floating plate 30. The inlet of the pump 23 is connected to the floating joint 29 through a connecting pipe. The outlet of the pump 23 is connected to the top middle part of the mixing tank 14 through a connecting pipe. The lower middle part of one side of the sand washing chamber 17 is connected to the upper middle part of one side of the sedimentation chamber 31 through a conveying pipe 11. An automatic filter valve 3 is installed on the end of the conveying pipe 11 near the sand washing chamber 17.

[0057] After the sand aggregate in the sand washing chamber 17 is washed, the wastewater circulation sedimentation mechanism is started. The staff opens the automatic filter valve 3 on the conveying pipe 11, so that the washing wastewater in the sand washing chamber 17 enters the sedimentation chamber 31 through the conveying pipe 11 for sedimentation.

[0058] When the mixture on the sieve plate 39 reaches the lower middle part of the mixing tank 14 after sieving, the pump 23 pumps the upper layer of cleaning wastewater that has been settled in the sedimentation chamber 31 through the connecting pipe, and injects it into the upper middle part of the inner side of the mixing tank 14 through the connecting pipe. As the liquid level in the sedimentation chamber 31 decreases, the floating plate 30 in the sedimentation chamber 31 descends synchronously. While the floating plate 30 descends synchronously, it drives the floating joint 29 and the connecting pipe on it to descend synchronously until the bottom of the floating plate 30 finally contacts the sediment layer at the bottom of the sedimentation chamber 31, thus completing the reuse of the cleaning sedimentation wastewater.

[0059] Please see the appendix Figure 6 - Appendix Figure 9 The material screening and mixing mechanism is located inside the mixing tank 14 and is used to screen and mix various materials used in the mortar and concrete processing to form mortar and concrete.

[0060] The material screening and mixing mechanism includes a screen plate 39, which is slidably connected to the upper middle part of the mixing barrel 14 near the top edge. The upper middle part of the inner wall of the mixing barrel 14 is fixedly connected to a mounting seat 38 by multiple connecting rods 35. An inner cavity 42 is provided in the middle of the inner side of the mounting seat 38. A mounting seat 43 and a mounting seat 44 are arranged sequentially from top to bottom in the lower middle part of the inner cavity 42. Multiple spherical protrusions 45 are arranged at equal intervals around the middle of the adjacent side of the mounting seat 43 and the mounting seat 44. The top of the mounting seat 43 is fixedly connected to one end of a connecting column 41. The other end of the connecting column 41 passes through the mounting seat 38 and is connected to the bottom middle of the screen plate 39. A support spring 40 is provided in the upper middle part of the inner side of the inner cavity 42.

[0061] When the material filtration and mixing mechanism is started, the raw material mixing and conveying mechanism conveys the uniformly mixed material to the screen plate 39 of the mixing tank 14 through the discharge pipe 15. Then, the drive motor 46 in the base 13 operates, and the shaft of the drive motor 46 drives the drive shaft 37 in the mixing tank 14 to rotate synchronously. While the drive shaft 37 rotates, it drives the mixing blade 36 and the mounting base 44 to rotate. While the mounting base 44 rotates, it drives the spherical protrusion 45 on it to rotate. As block 45 rotates, it causes mounting seat 2 43 in the inner cavity 42 to repeatedly move up and down radially. The support spring 40 on mounting seat 2 43 and mounting seat 3 44 at its bottom cause it to move up and down radially, which in turn causes the connecting column 41 and screen plate 39 to vibrate up and down synchronously. This vibrates the mixture on screen plate 39, causing it to fall through the screen holes on screen plate 39 into the middle and lower part of mixing bucket 14, thereby preventing large particles in the mixture from affecting the normal use of subsequent mortar and concrete.

[0062] When the washing wastewater after sedimentation is discharged into the mixing tank 14, the discharged washing wastewater can also wash the material on the screen plate 39, accelerate the falling speed of the material on the screen plate 39, and also improve the screening speed of the material on the screen plate 39.

[0063] The material screening and mixing mechanism includes a base 13, the top center of which is fixedly connected to the bottom of a mixing tank 14. The bottom center of the inner side of the mixing tank 14 is rotatably connected to one end of a second drive shaft 37. The other end of the second drive shaft 37 passes through a first mounting base 38 and is connected to the bottom center of a third mounting base 44. Multiple mixing blades 36 are equidistantly arranged on the outer wall of the second drive shaft 37. A third drive motor 46 is arranged in the inner center of the base 13, and the output end of the third drive motor 46 passes through the base 13 and is connected to the bottom of the second drive shaft 37. A discharge pipe 22 is arranged in the lower rear part of the mixing tank 14, and a control valve 21 is arranged on the discharge pipe 22. The lower side of the base 13 is connected to the bottom of the main box 1 through a support frame 12.

[0064] When the mixed materials after screening and the washing wastewater after sedimentation reach the lower inner part of the mixing tank 14, the drive shaft 37 rotates and drives the mixing blade 36 on it to rotate synchronously, thereby mixing and stirring the mixed materials into mortar concrete. After the mixing is completed, the operator can open the control valve 21 on the discharge pipe 22 to discharge the mortar concrete in the mixing tank 14 through the discharge pipe 22 for use.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
