Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fine proportioning feeding device for composite concrete. Background Art

[0002] Concrete is widely used in building construction due to its advantages such as high compressive strength, good durability and fire resistance. Concrete is a composite material prepared by mixing cementitious materials, aggregates, water, admixtures and other materials in a certain proportion. When preparing concrete, the proportion of each component needs to be strictly controlled to ensure the performance of concrete.

[0003] In the existing component proportion control method, multiple materials are respectively placed in multiple storage containers, and then the multiple materials are put onto an inclined loading platform. A pressure sensor is arranged at the bottom of the loading platform. After the materials are weighed, they enter the mixing chamber under the action of gravity. If concrete is prepared by this method, the multiple materials only enter the mixing chamber under the action of gravity, and there is more residual material on the loading platform, thus causing an incorrect mixing ratio of concrete, resulting in a reduction in the performance such as the compressive strength of concrete, and seriously affecting the overall quality and safety of the project.

[0041] As Figures 1 to 6 shown, this embodiment provides a compound concrete fine proportion feeding device, which can be used to prepare composite materials composed of multiple materials such as concrete, and can more accurately control the mixing ratio of each material to ensure the material properties of the composite material.

[0042] As Figures 1 to 3As shown, the composite concrete fine proportioning feeding equipment comprises a mixing container 1, a batching unit 2 and a driving unit 3. The mixing container 1 is provided with a mixing chamber for containing all materials constituting the concrete, and all materials are mixed evenly in the mixing container 1, thereby obtaining concrete material.

[0043] The batching unit 2 includes a main shell 21, a partition assembly 22 and a weighing platform 23. The main shell 21 is arranged above the mixing container 1, and the main shell 21 is provided with a feed chamber 214 and a discharge channel 211 from top to bottom, and the feed chamber 214 is connected with the mixing chamber through the discharge channel 211. The partition assembly 22 is arranged in the feed chamber 214, so as to divide the feed chamber 214 into a plurality of independent chambers 212. Each independent chamber 212 is respectively filled with different materials to prevent mutual interference between materials and avoid affecting the preparation ratio. In addition, the partition assembly 22 can move vertically, and the partition assembly 22 has a partition position that blocks the independent chamber 212 and the discharge channel 211 and a conduction position that connects the independent chamber 212 and the discharge channel 211. The bottom wall of each independent chamber 212 is provided with a weighing platform 23, which can be used to detect the weight of the material entering the independent chamber 212, so as to facilitate more accurate determination of the proportion of various materials and ensure the material properties of the concrete. The driving unit 3 is arranged in the main shell 21, and the driving unit 3 is connected to the partition assembly 22 by transmission. The driving unit 3 can drive the partition assembly 22 to move from the separation position to the conduction position, thereby connecting the independent chamber 212 and the discharge channel 211. At the same time, the driving unit 3 can also push the material in the independent chamber 212 to the discharge channel 211, so that all the materials enter the mixing container 1, preventing the preparation ratio from being incorrect due to material residue, and avoiding affecting the performance of the concrete.

[0044] When preparing concrete, first determine that the partition component 22 is in the separation position. At this time, the feed chamber 214 is divided into multiple independent chambers 212, and the independent chambers 212 and the discharge channel 211 are blocked to prevent materials of undetermined weight from entering the mixing container 1; then, the preset weights of various components of the concrete are determined according to the preparation ratio, and the multiple materials are respectively injected into the multiple independent chambers 212, so that the materials are accumulated on the weighing platform 23. When the weighing platform 23 detects that the weight of the injected material is equal to the preset weight, the injection is stopped, and the driving unit 3 drives the partition component 22 to move vertically, so that it switches from the separation position to the conduction position, thereby connecting the independent chamber 212 and the discharge channel 211. At the same time, the driving unit 3 pushes the material in the independent chamber 212 to the discharge channel 211 and enters the mixing container 1.

[0045] By setting up the weighing platform 23, the weight of the fed materials can be detected more accurately, so as to precisely control the mixing ratio of various materials. Moreover, the pushing component 32 can push the materials into the mixing container 1 more completely, preventing excessive materials from remaining in the independent chamber 212, avoiding inaccurate mixing ratios, and enabling the prepared concrete to have high compressive strength and good durability, thereby ensuring the overall quality and safety of the project. In addition, through the collaborative cooperation of the mixing container 1, the batching unit 2, and the driving unit 3, operation steps such as material transportation can be reduced, and the working efficiency of preparing concrete can be improved.

[0046] Exemplarily, the weighing platform 23 includes a pressure sensor.

[0047] In this embodiment, the feeding chamber 214 is divided into 4 independent chambers 212. In other embodiments, according to actual needs, the feeding chamber 214 can also be divided into 2 to 3, or more than 4 independent chambers 212, which is not limited here.

[0048] Optionally, as Figures 3 to 5 shown, the partitioning component 22 includes a material separating member 221 and a blocking member 222 connected vertically. One end of the material separating member 221 away from the blocking member 222 is in transmission connection with the driving unit 3. A plurality of insertion grooves 2211 are arranged at intervals along the circumferential direction of the outer wall of the material separating member 221. A partitioning ridge 213 is arranged between adjacent two independent chambers 212, and the partitioning ridge 213 is inserted into the insertion groove 2211 and is slidably matched with the insertion groove 2211. Through the collaborative cooperation of the insertion groove 2211 and the partitioning ridge 213, the outer wall of the material separating member 221 can just be closely attached to the inner wall of the feeding chamber 214. Refer to Figure 6 so as to realize that the feeding chamber 214 is divided into multiple independent chambers 212 by the material separating member 221, and completely block the communication between each independent chamber 212.

[0049] In addition, when the driving unit 3 drives the material separating member 221 and the blocking member 222 to move vertically, the partitioning ridge 213 moves vertically along the insertion groove 2211. The insertion groove 2211 can provide a guiding function for the material separating member 221 and the blocking member 222, prevent the partitioning component 22 from shifting, and avoid the communication between independent chambers 212 during the partitioning position.

[0050] The cross-sectional area of the feed chamber 214 is larger than that of the discharge channel 211, and a stepped structure is formed at the junction of the feed chamber 214 and the discharge channel 211. The cross-sectional area of the material separating member 221 is larger than that of the plugging member 222, and the material separating member 221 and the plugging member 222 form a stepped groove. When the separating assembly 22 is in the separating position, the stepped groove can be engaged with the stepped structure, so as to completely block the connection between the discharge channel 211 and the plurality of independent chambers 212, prevent the material of undetermined weight from entering the mixing container 1, and avoid incorrect preparation.

[0051] It should be noted that the number of the insertion grooves 2211, the number of the separating ridges 213 is the same as the number of the independent chambers 212.

[0052] In this embodiment, there are 4 insertion grooves 2211 and 4 separating ridges 213. The feed chamber 214 is integrally in a cross-shaped structure, and the separating assembly 22 is located in the middle of the cross-shaped structure, separating the feed chamber 214 into four independent chambers 212. In other embodiments, according to actual needs, 2 to 3, or more than 4 insertion grooves 2211 and separating ridges 213 can also be provided, which is not limited here.

[0053] Optionally, as Figure 1 and Figure 3 shown, the driving unit 3 includes a driving mechanism 31 and a material pushing assembly 32. The housing of the driving mechanism 31 is arranged on the main housing 21, and the output end of the driving mechanism 31 is in transmission connection with the material pushing assembly 32. After the weighing of the material is completed, the driving mechanism 31 drives the material pushing assembly 32 to move horizontally on the weighing platform 23, so that the material pushing assembly 32 pushes all the materials in the independent chamber 212 into the discharge channel 211, and then falls into the mixing container 1, preventing the materials from remaining in the independent chamber 212, so as to ensure a relatively accurate preparation ratio of various materials and ensure the material properties of the concrete.

[0054] Exemplarily, the driving mechanism 31 includes a cylinder or an electric cylinder.

[0055] Optionally, as Figure 3As shown, the pusher assembly 32 includes a transmission connecting member 322 and a plurality of pusher members 321. The plurality of pusher members 321 are respectively arranged above the plurality of weighing platforms 23, and are used to simultaneously push the materials on the plurality of weighing platforms 23 into the discharge channel 211. The transmission connecting member 322 includes a first connecting rod 3221, a connecting bracket 3222 and a plurality of first pushing blocks 3223. One end of the first connecting rod 3221 is connected to the separating assembly 22, and the separating assembly 22 is in transmission connection with the output end of the driving mechanism 31. The other end of the first connecting rod 3221 is connected to the connecting bracket 3222, and the plurality of first pushing blocks 3223 are all connected to the connecting bracket 3222. The first pushing block 3223 is located on the side of the corresponding pusher member 321 away from the independent chamber 212. Each first pushing block 3223 is provided with a first guiding inclined surface 3224, and the first guiding inclined surface 3224 gradually approaches the independent chamber 212 from top to bottom. The first guiding inclined surface 3224 is slidably matched with the end of the pusher member 321 away from the feeding chamber 214.

[0056] When the driving mechanism 31 drives the separating assembly 22 to move vertically, the separating assembly 22 can drive the first connecting rod 3221 to move vertically, and then the first connecting rod 3221 drives the first pushing block 3223 to move vertically through the connecting bracket 3222. At the same time, the end of the pusher member 321 away from the feeding chamber 214 slides along the first guiding inclined surface 3224, so that the first pushing block 3223 pushes the pusher member 321 to move along the weighing platform 23, thereby realizing that the pusher member 321 pushes all the materials in the independent chamber 212 into the discharge channel 211, ensuring the accuracy of the preparation ratio.

[0057] It should be noted that the first pushing block 3223 is in sliding contact with the upper surface of the weighing platform 23 in the independent chamber 212 to ensure that all the materials on the weighing platform 23 are pushed into the discharge channel 211.

[0058] Optionally, the end of the pusher member 321 close to the first pushing block 3223 is provided with a second guiding inclined surface. The second guiding inclined surface of the pusher member 321 is slidably matched with the first guiding inclined surface 3224 of the first pushing block 3223. When the first pushing block 3223 moves vertically, the first pushing block 3223 can push the pusher member 321 to move along the weighing platform 23. During this process, the second guiding inclined surface of the pusher member 321 will slide along the first guiding inclined surface 3224, and the first guiding inclined surface 3224 and the second guiding inclined surface are always in close contact, so that the pusher member 321 remains stable during the movement, preventing the pusher member 321 from tilting and causing insufficient pushing, and avoiding material residue.

[0059] Optionally, as Figure 2 and Figure 3As shown in the figure, the pusher 321 includes a connected second connecting rod 3212 and a second pusher block 3213. One end of the second connecting rod 3212 away from the second pusher block 3213 is slidably engaged with the first guiding inclined surface 3224. The second pusher block 3213 is movably arranged in the main housing 21 in the horizontal direction, and together with the inner wall of the feeding cavity 214 and the separating assembly 22, an independent chamber 212 is formed. When adding materials, one end of the second connecting rod 3212 away from the second pusher block 3213 is in sliding contact with the upper end of the first guiding inclined surface 3224. At this time, the second pusher block 3213 is arranged on the main housing 21 and does not push the materials. After the material is put in place, the first pusher block 3223 moves vertically, thereby pushing the second pusher block 3213 to move horizontally into the independent chamber 212 through the second connecting rod 3212, and pushing the materials in the independent chamber 212 to the discharge channel 211.

[0060] In some embodiments, the pusher 321 further includes a scraping member. The scraping member is arranged at one end of the second pusher block 3213 close to the weighing platform 23, and the lower end of the scraping member is in contact with the upper surface of the weighing platform 23. When pushing the materials, the second connecting rod 3212 pushes the second pusher block 3213 and the scraping member to move horizontally on the weighing platform 23. The materials are jointly pushed to the discharge channel 211 by the second pusher block 3213 and the scraping member. Moreover, the lower end of the scraping member is in contact with the upper surface of the weighing platform 23, which can make the materials be more completely pushed to the discharge channel 211 and enter the mixing container 1, reducing material residue, thereby more accurately controlling the mixing ratio of various materials forming the concrete, and making the prepared concrete have higher compressive strength and good durability.

[0061] Exemplarily, the scraping member includes a rubber scraping blade. In other embodiments, according to actual needs, items made of flexible materials such as brushes can also be selected, which are not limited here.

[0062] Optionally, as Figure 3 shown, the pusher 321 further includes a guide rod 3214. A sliding groove 216 is formed on the side wall of the main housing 21. One end of the guide rod 3214 is connected to the second connecting rod 3212, and the other end is movably arranged in the sliding groove 216 in the horizontal direction. When the first pusher block 3223 pushes the second pusher block 3213 to move horizontally, the guide rod 3214 moves horizontally in the sliding groove 216. By providing the sliding groove 216 and the guide rod 3214, a guiding effect can be further provided for the second pusher block 3213, preventing the second pusher block 3213 from tilting and ensuring that the materials are completely pushed.

[0063] In this embodiment, the guide rod 3214 is set as an L-shaped rod, one end of which is connected to the second connecting rod 3212, and the other end is slidably engaged with the sliding groove 216. In other embodiments, according to actual needs, the guide rod 3214 can also be set in the form of a stepped rod, etc., which is not limited herein.

[0064] Optionally, as Figure 1 and Figure 2 shown, the compound concrete fine proportioning feeding device further includes a plurality of feeding hoppers 4. The plurality of feeding hoppers 4 are all arranged on the outer wall of the main housing 21 and are located above the independent chambers 212. The plurality of feeding hoppers 4 are in one-to-one communication with the plurality of independent chambers 212. When adding materials, various materials can be respectively added into the plurality of feeding hoppers 4. Under the action of gravity, the materials fall from the feeding hoppers 4 into the independent chambers 212. By providing the feeding hoppers 4, a storage space can be provided, the single feeding amount can be increased, and the materials can be guided to quickly enter the independent chambers 212, improving the feeding efficiency. In addition, it can also prevent the materials from spilling during the feeding process, keep the working environment clean, and reduce the waste of materials.

[0065] Exemplarily, the feeding hopper includes a rectangular funnel. In other embodiments, according to actual needs, the feeding hopper can also be set as a conical funnel, etc., which is not limited herein.

[0066] Optionally, as Figure 2 shown, a guiding channel 5 is provided between the feeding hopper 4 and the independent chamber 212. The guiding channel 5 is provided with a third guiding inclined surface 51, and the third guiding inclined surface 51 extends obliquely from top to bottom. When feeding, the materials first enter the guiding channel 5 from the feeding hopper 4. Some materials will directly fall from the guiding channel 5 into the independent chamber 212, while some materials will pile up on the third guiding inclined surface 51 and slide along the third guiding inclined surface 51 under the action of gravity until they fall into the independent chamber 212. By providing the third guiding inclined surface 51, the materials can be automatically guided, preventing the materials from piling up and settling, and reducing the waste of materials.

[0067] Optionally, as Figures 2 to 4 shown, the compound concrete fine proportioning feeding device further includes a limiting boss 6. The limiting boss 6 protrudes from the inner wall of the discharge channel 211 and is located below the partition assembly 22. By providing the limiting boss 6, on the one hand, the blocking between the independent chamber 212 and the discharge channel 211 can be further enhanced, and on the other hand, a limiting effect can be provided for the sealing member 222 to prevent the partition assembly 22 from falling into the discharge channel 211, ensuring the normal operation of the device.

[0068] In this embodiment, the upper surface of the limiting boss 6 is set to extend obliquely from top to bottom.
