Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and in particular relates to a mixing device for construction engineering. Background Art

[0002] The construction process of modern construction projects is closely related to building materials such as mud, mortar, and concrete. Therefore, mixing devices for construction projects are also widely used in various construction sites. The main purpose of this type of equipment is to evenly mix a variety of building raw materials, and the resulting products are mostly used in places such as wall building, pouring, and coating. The uniformity and fineness of the final mixed product will affect the quality of the building. For example, when the building materials have problems such as agglomeration and uneven particles, it will simultaneously cause subsequent building cracks and lifespan issues. This is the direction that this solution focuses on solving.

[0003] For example, patent application No. CN202122574482.X discloses a mixing device for construction projects, including a mixing box, a crushing barrel is fixedly connected to the top wall of the mixing box, a mixing barrel is fixedly connected to the middle of the bottom wall of the mixing box, a center rod is rotatably embedded between the mixing barrel and the top wall of the mixing box, and a push plate, a stirring plate, and spiral blades are sequentially distributed on the center rod from top to bottom, wherein the middle part of the crushing barrel presents a mesh structure, and a plurality of fixed rods are symmetrically distributed on both sides of the inner wall of the crushing barrel. The utility model provides a mixing device for construction projects, which can filter materials through the arrangement of the pushing plate and the crushing barrel, and fine fixed particles can enter the mixing box, and the agglomerated materials are accumulated in the mixing box, and can be crushed by the fixed rod when the pushing plate rotates until the agglomerates are crushed, thereby avoiding the problem that the coating raw materials cannot maintain good viscosity due to agglomeration, which will directly affect the appearance of the coating.

[0004] In the prior art, the setting of the crushing cylinder and the mixing cylinder ensures that the mixed product does not agglomerate, but there are still certain shortcomings in the overall use process:

[0005] 1. The crushing ability of the crushing drum for lumps is limited. Some building materials may contain large block solids, such as sand, gravel, mud, etc. The existing technology can only complete a single rough crushing. There will still be a certain amount of large particles of material after crushing, but it is impossible to perform secondary fine crushing on the incompletely crushed materials. The overall crushing quality is poor, resulting in a decrease in the mixing effect.

[0006] 2. During the crushing and mixing of building materials, the machine will vibrate and shake, which are not conducive to the stability of the machine's operation. Vibration and shaking can also cause problems such as circuit welding falling off and button failure in the machine. The existing technology lacks a design that can increase the stability of the device and reduce vibration. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model provides a mixing device for construction engineering.

[0008] The utility model can crush, filter and recycle materials of larger volumes for multiple times, effectively ensuring the crushing and refining quality and improving the mixing effect. At the same time, the arrangement of the filling cabin and the third feed port lowers the overall center of gravity of the equipment, effectively improving the stability during operation and ensuring production safety.

[0009] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mixing device for construction engineering, comprising a base and a shell, the upper end surface of the base is fixedly provided with the shell, the upper end surface of the shell is provided with a first feed port, below the first feed port, a first crushing assembly and a second crushing assembly are arranged up and down in the shell, a vibration filter plate is obliquely arranged below the second crushing assembly, a plurality of vibration assemblies are connected to the lower end surface of the vibration filter plate, a recovery channel is provided in the shell on the inclined side of the vibration filter plate, a recovery push plate is slidably provided at one end of the recovery channel, and the other end of the recovery channel is connected and provided on the outer circular surface of the lower end of the lifting cylinder, a lifting auger is rotatably provided in the lifting cylinder, a feeding pipe is connected to the upper end of the lifting cylinder, and the other end of the feeding pipe is aligned with the first feed port; a mixing chamber is also provided below the vibration filter plate, a plurality of mixing rods are rotatably provided in the mixing chamber, and a first discharge port is provided at the bottom of the mixing chamber.

[0010] During the operation of the device, production personnel can feed materials from the first feed port, and the raw building materials will pass through the first crushing component and the second crushing component in turn, and then the vibration filter plate under the second crushing component will filter out the building materials with uniform size and up-to-standard particle size and enter the mixing chamber for mixing; substandard agglomerated materials and building materials with too large particle size will roll down the inclined vibration filter plate to the recovery channel, and the recovery push plate at one end of the recovery channel will push them into the lifting cylinder, which will cooperate with the lifting auger therein to lift these substandard building materials to a high place, and then feed them into the first feed port through the feeding cylinder for re-crushing and filtering and other steps; after the building materials in the mixing chamber are mixed, the production personnel can operate to open the first discharge port to discharge the materials.

[0011] Preferably, a filling cabin is further provided in the base, a third feed port connected to the filling cabin is provided on the upper end surface of the base, and a third discharge port connected to the filling cabin is provided at the bottom end of one side of the base.

[0012] During use, production personnel can open the third feed port to fill the filling chamber in the base. The filler can be water, mud, etc., which depends on the specific conditions of the construction site. This plan will not elaborate on this. After filling, the setting of the filling chamber will make the overall center of gravity of the device lower and more stable during operation, and increasing the mass of the device itself can have a certain shock-absorbing and buffering effect, which helps prevent the failure of the device circuit. When production personnel need to move the device, they can discharge the filler in the filling chamber through the third discharge port, thereby reducing the difficulty of transportation.

[0013] Preferably, the first crushing assembly includes two first bearing seats symmetrically arranged on the inner side of the shell, two first support shafts are rotatably arranged between the two first bearing seats, each of the first support shafts is linearly arranged with a plurality of first crushing teeth, and the first crushing teeth between the two first support shafts are mutually meshed.

[0014] The first crushing component is a toothed roller crushing mechanism. During the specific crushing process, when the production personnel pour the construction raw materials into the device from the first feed port, the crushing teeth in the first crushing component will crush the larger lumps and solids in the construction raw materials, and serve as pretreatment for the subsequent crushing of the second component.

[0016] The second crushing assembly is still a tooth-roller crushing mechanism. The difference between the first crushing assembly and the second crushing assembly is that the meshing gap between the second crushing teeth is smaller than the meshing gap between the first crushing teeth. The second crushing assembly will further crush the raw materials, making the processed building materials more uniform and delicate, which is conducive to the subsequent mixing process.

[0017] Preferably, a discharge valve is provided on the upper end surface of the first discharge port at the bottom of the mixing chamber, and a discharge pump is provided on the outer end surface of the first discharge port.

[0018] After the mixing is completed, the production staff can operate the discharge valve and the discharge pump to open so that the mixed building materials can be discharged from the first discharge port.

[0019] Preferably, a height detector is fixedly installed on the side wall of the mixing chamber.

[0020] The height detector can monitor the height of the material in the mixing chamber to prevent excessive material from overflowing above the vibrating filter plate; when the height detector detects that the building materials in the mixing chamber have reached the set value, the information can be transmitted to the production personnel through the display to prompt the production personnel to stop feeding. The specific setting height refers to the specific situation of construction production, and this plan will not elaborate on it.

[0021] Preferably, an electric push rod is provided on one side of the recovery channel, and the output end of the electric push rod is interconnected with the recovery push plate.

[0022] When the substandard building materials on the recycling channel accumulate to a certain amount, the output end of the electric push rod can drive the recycling push plate to send the substandard building materials into the lifting cylinder. The specific amount of building materials accumulated refers to the specific environment setting of the construction site, and this plan will not elaborate on it in detail.

[0023] Preferably, a detection component is fixedly provided on the upper end surface of the base, and a display screen is fixedly provided on the outer side surface of the detection component away from the shell.

[0024] The detection component can monitor the vibration of the device. If the vibration and shaking of the device are too large, the device can transmit information to the production personnel through the display screen, prompting the production personnel to continue to add fillers to the filling chamber. The display screen plays the role of displaying information and device status, and the production personnel can exchange information through the display screen.

[0025] Preferably, the vibration filter plate is provided with a plurality of filter holes arranged in an array.

[0026] The filter holes play the role of filtering building materials, and production personnel can limit the building materials filtered out by setting the shape and size of the filter holes.

[0027] Preferably, each stirring rod is linearly provided with a plurality of stirring heads.

[0028] The mixing head plays a stirring role and can mix the qualified building materials in the mixing chamber and mix the building materials into a uniform mixed product.

[0029] In summary, compared with the prior art, the beneficial effects of this solution are:

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0043] Embodiment 1:

[0044] Reference Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 5 A mixing device for construction engineering includes a base 10 and a shell 14, wherein the shell 14 is fixedly arranged on the upper end surface of the base 10, a first feed port 12 is arranged on the upper end surface of the shell 14, and a first crushing assembly and a second crushing assembly are arranged in an upper and lower arrangement in the shell 14 below the first feed port 12. When in use, the construction raw materials fall into the device from the first feed port 12, and are crushed by the first crushing assembly and the second crushing assembly in turn.

[0045] For further information, see Attachment Figure 3 , Attachment Figure 6 And attached Figure 7 The first crushing assembly includes two first bearing seats 24 symmetrically arranged on the inner side of the shell 14, two first support shafts 44 are rotatably arranged between the two first bearing seats 24, and a plurality of first crushing teeth 21 are linearly arranged on each first support shaft 44, and the first crushing teeth 21 between the two first support shafts 44 are mutually meshed. One end of the first support shaft 44 extends out of the shell 14, and a first driving device 20 is fixedly arranged at a corresponding position of the shell 14, and the output end of the first driving device 20 is interconnected with the first support shaft 44. The output end of the first driving device 20 will drive the first support shaft 44 to rotate, thereby driving the plurality of first crushing teeth 21 on the outer circumferential surface of the first support shaft 44 to rotate. All driving devices appearing in this embodiment are prior art, and this scheme will not be elaborated in detail, and the same will be repeated in the following text.

[0046] Similarly, the second crushing assembly includes two second bearing seats 25 symmetrically arranged on the inner side of the housing 14, the second bearing seats 25 are located below the first bearing seat 24, and two second support shafts 45 are rotatably arranged between the two second bearing seats 25, and a plurality of second crushing teeth 22 are linearly arranged on each second support shaft 45, and the second crushing teeth 22 between the two second support shafts 45 are mutually meshed. One end of the second support shaft 45 extends out of the housing 14, and a second driving device 29 is fixedly arranged at a corresponding position of the housing 14, and the output end of the second driving device 29 is interconnected with the second support shaft 45. The output end of the second driving device 29 drives the second support shaft 45 to rotate, thereby driving the plurality of second crushing teeth 22 on the outer circumferential surface of the second support shaft 45 to rotate.

[0047] In the specific crushing process, the difference between the first crushing component and the second crushing component is that the meshing gap between the plurality of first crushing teeth 21 is larger than the meshing gap between the plurality of second crushing teeth 22. When the production personnel pour the construction raw materials into the device from the first feed port 12, the first crushing component will crush the larger lumps and solids in the construction raw materials, and then the second crushing component will further crush the raw materials, so that the processed construction materials are more uniform and delicate, which is conducive to the subsequent mixing process.

[0048] For further information, see Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 A vibration filter plate 23 is obliquely arranged below the second crushing assembly, and a plurality of filter holes 28 are arranged in an array on the vibration filter plate 23. Two first support plates 26 are obliquely arranged on the outer shell 14 below the vibration filter plate 23, and a plurality of vibration components 27 are fixedly arranged on the first support plates. The output end of each vibration component 27 is connected to the lower end surface of the vibration filter plate 23, and a stirring chamber 41 is arranged below the vibration filter plate 23. A recovery channel 34 is also arranged on the inclined side of the vibration filter plate 23 in the outer shell 14.

[0049] During the specific process, the construction materials that have passed through the second crushing component will fall evenly on the vibration filter plate 23. Construction materials that meet the particle size can fall into the mixing chamber 41 through the multiple filter holes 28 on the vibration filter plate 23, while agglomerated construction materials or solids with too large particles cannot pass through. According to the needs of the construction site, production personnel can set the size and shape of the filter holes 28 by themselves, and this solution does not impose too many restrictions. Multiple vibration components 27 will be started to vibrate the vibration filter plate 23. At this time, the vibration filter plate 23 vibrates continuously. On the one hand, this setting can prevent the construction materials that cannot pass through the filter holes 28 from getting stuck in the filter holes 28. On the other hand, it can also promote the construction materials that cannot pass through the filter holes 28 to roll down to the recovery channel 34 along the inclination angle of the vibration filter plate 23, thereby preparing for the subsequent recovery of substandard construction materials. The vibration component 27 is a prior art, and this solution will not be elaborated on in detail.

[0050] For further information, see Attachment Figure 4 With attached Figure 6 , an electric push rod 31 is provided on one side of the recycling channel 34, the output end of the electric push rod 31 is connected to the recycling push plate 35, the recycling push plate 35 and the recycling channel 34 can slide together, and the other end of the recycling channel 34 is connected and arranged on the outer circumferential surface of the lower end of the lifting cylinder 15, and a second feed port 17 is provided on the outer circumferential surface of the lifting cylinder 15 at a position corresponding to the recycling channel 34. The electric push rod 31 is a prior art, and this scheme will not be elaborated in detail. When the building materials on the recycling channel 34 accumulate to a certain amount, the output end of the electric push rod 31 will push the recycling push plate 35, so that the building materials can be pushed into the lifting cylinder 15.

[0051] A lifting auger 16 is rotatably arranged in the lifting cylinder 15, and a third driving assembly 30 is fixedly arranged above the lifting cylinder. The upper end of the shaft of the lifting auger 16 extends out of the lifting cylinder 15 and is connected to the output end of the third driving assembly 30. A feeding pipe 19 is connected to the upper end of the lifting cylinder 15, and a second discharge port 18 is arranged at the other end of the feeding pipe 19, and the second discharge port 18 is aligned with the first feed port 12. In this relationship, the building materials that cannot pass through the vibrating filter plate 23 will be pushed into the lifting cylinder 15 by the recycling push plate, and the lifting auger 16 in the lifting cylinder 15 can transport it upwards. Subsequently, the substandard building materials are sent into the feeding pipe 19 by the lifting auger, and then sent into the first feed port 12 by the feeding pipe 19, so that the substandard building materials can re-enter the device for crushing and filtration.

[0052] For further information, see Attachment Figure 3 , Attachment Figure 4 With attached Figure 6 And attached Figure 8 A mixing chamber 41 is also provided below the vibration filter plate 23. A plurality of stirring rods 32 are rotatably provided in the mixing chamber 41. A plurality of stirring heads 33 are linearly provided on each stirring rod 32. A plurality of fourth driving devices 46 are fixedly provided outside the mixing chamber 41. One end of each stirring rod 32 extends out of the mixing chamber 41 and is connected to the fourth driving device 46. The fourth driving device 46 drives the stirring rod 32 to rotate. Qualified building materials can pass through the plurality of filter holes 28 on the vibration filter plate 23 and fall into the mixing chamber 41. The stirring rod 32 can drive the plurality of stirring heads 33 thereon to rotate together, thereby thoroughly mixing the building materials in the mixing chamber.

[0053] For further information, see Attachment Figure 3 , Attachment Figure 4 And attached Figure 7 A height detector 36 is also fixedly provided on the side wall of the mixing chamber 41. The height detector 36 can detect the height of the building materials in the mixing chamber 41. The height of the building materials cannot exceed the vibration filter plate 23, otherwise the filtered building materials will overflow above the vibration filter plate 23. When the height detector 36 detects that there are too many building materials in the mixing chamber 41, the device can display the information to the production personnel through the display screen 43 and stop feeding.

[0054] For further information, see Attachment Figure 3 , Attachment Figure 4 And attached Fig. 9 A first discharge port 13 is provided at the bottom of the mixing chamber 41, a discharge valve 39 is provided on the upper end surface of the first discharge port 13 at the bottom of the mixing chamber 41, and a discharge pump 40 is provided on the outer end surface of the first discharge port 13. After the mixing is completed, the production staff can operate the discharge valve 39 and the discharge pump 10 to open, so that the mixed building materials can be discharged from the first discharge port 13.

[0055] Specifically, in the manufacturing process of the present embodiment, the production personnel will initially put the construction raw materials into the first feed port 12; the construction raw materials first pass through the first crushing assembly, and the lumps and large solids in the construction raw materials are crushed by the first crushing teeth 21 therein and passed through the second crushing assembly together with other raw materials for further crushing. After crushing, the construction materials will fall on the vibration filter plate 23, and a plurality of filter holes 28 are arranged in an array on the vibration filter plate 23. The construction materials that meet the particle size standards will pass through the filter holes 28 and fall into the mixing chamber 41 below, while the construction materials that do not meet the standards will be blocked by the vibration filter plate 23. The vibration filter plate 23 is tilted at a certain angle, and cooperates with the multiple vibration components 27 connected to the lower end surface of the vibration filter plate 23, so that the construction materials that do not meet the standards will not be stuck in the filter holes 28 but will roll down to the recovery channel 34.

[0056] When the substandard building materials accumulate to a certain amount on the recycling channel 34, the electric push rod 31 is started, and the output end of the electric push rod 31 drives the recycling push plate 34 to push the substandard building materials into the lifting cylinder 15. The lifting auger 16 arranged in the lifting cylinder 15 rotates with the cooperation of the third driving device 30. During this process, the lifting auger 16 can transport the building materials at the bottom of the lifting cylinder 15 to the upper end of the lifting cylinder 15. After the building materials reach the upper end of the lifting cylinder 15, the building materials will enter the feeding cylinder 19 and enter the first feeding port 12 from the second discharge port at the end of the feeding cylinder 19. Subsequently, the substandard building materials will be crushed and filtered again until they can pass through the filter hole 28.

[0057] When the qualified building materials fall into the mixing chamber 41 for mixing, the multiple mixing rods 32 in the mixing chamber 41 rotate, and each mixing rod 32 is provided with multiple mixing heads 33, which can mix the building materials in the mixing chamber 41, so that the building materials are fully mixed. A height detector 36 is also fixedly provided on the side wall of the mixing chamber 11.

[0058] After the mixing process is completed, the uniform mixed product is stored in the mixing chamber 41 , and the production personnel can operate to open the discharge valve 39 and the discharge pump 40 on the first discharge port 13 , so that the mixed product can be discharged smoothly from the first discharge port 13 .

[0059] Embodiment 2:

[0060] Reference Figure 3 , Attachment Figure 4 , and attached Figure 6A mixing device for construction engineering, a filling cabin 11 is arranged in a base 10, a third feed port 37 connected to the filling cabin 11 is arranged on the upper end surface of the base 10, and a third discharge port 38 connected to the filling cabin 11 is arranged on the bottom end of one side of the base 10; a detection component 42 is also fixedly arranged on the upper end surface of the base 10, and a display screen 43 is fixedly arranged on the outer side surface of the detection component 42 away from the outer shell 14.

[0061] As a further embodiment, during use, the production personnel can open the third feed port 37 to fill the filling chamber 11 in the base 10. The filler can be water, mud, etc., which depends on the specific conditions of the construction site. This solution will not elaborate on this. After filling, the setting of the filling chamber 11 will make the overall center of gravity of the device lower and more stable during operation, and increasing the mass of the device itself can have a certain shock-absorbing and buffering effect, which helps to prevent the failure of the device circuit. When the production personnel need to carry the device, the filler in the filling chamber 11 can be discharged through the third discharge port 37, thereby reducing the difficulty of carrying.

[0062] When the detection component 42 detects that the vibration is too large during the operation of the device, the information can still be fed back to the production personnel through the display screen 43, and the production personnel can continue to add fillers to the filling chamber 11. A display screen 43 is fixedly arranged on the outer surface of the detection component 42 away from the shell 14, and the production personnel can exchange information through the display screen.

[0063] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0064] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
