Technical Field
[0001] The utility model relates to the technical field of construction equipment, in particular to a split high-ductility concrete mixing device. Background Art
[0002] High ductility concrete is a fiber-reinforced composite material based on the design principles of micromechanics and with cement, quartz sand, etc. as the matrix. It has high ductility, high damage resistance, high durability, high strength (compression and tension), and good crack control ability. It is also called "bendable concrete."
[0003] Special mixing equipment is required for mixing high-ductility concrete. If the mixing equipment is not properly selected or the mixing method is incorrect, it may cause uneven mixing of the concrete, affecting the quality of the concrete. In the prior art, technicians usually use a mixer to achieve this operation. Specifically, cement, quartz sand and other materials are put into the mixer. The mixer rotates in a cylinder or a groove through an axis with blades to mix a variety of raw materials. However, the mixer still has the following problems during use: the overall structure of the mixing device is complex, the manufacturing cost is high, and the mixing barrel is fixedly set on the mixing mechanism. For different environments, the mixing device needs to be moved as a whole, so it is not convenient for miniaturization.
[0004] For example, the patent document with publication number CN220741679U in the prior art discloses a concrete mixer that can be used to mix high-ductility concrete. The concrete mixer includes: a support frame, a mixing barrel is rotatably connected to the inside of the support frame, a discharge pipe is fixedly connected to the bottom of the mixing barrel, a valve is sleeved on the surface of the discharge pipe, a mixing assembly is arranged inside the support frame, and the mixing assembly includes a mixing motor, the output end of the mixing motor is connected to a mixing rod through a coupling, two mixing blades are fixedly connected to the surface of the mixing rod, and a cleaning assembly is arranged on the surface of the mixing rod. Although the scheme can achieve the mixing of the concrete by the mixing blades and the cleaning assembly arranged on the surface of the mixing rod, the concrete on the inner wall of the mixing barrel can be cleaned at the same time, but because the mixing barrel is rotatably connected to the support frame and the mixing assembly is also arranged inside the support frame, the overall equipment structure is complicated and the manufacturing cost is high. Moreover, if the equipment is transported to a different environment for use, the equipment support frame needs to be moved as a whole, resulting in greater construction difficulty.
[0005] Therefore, in the prior art, the mixing device for mixing high-ductility concrete has the technical problem of being inconvenient to use. Utility Model Content
[0006] The utility model aims to solve the technical problem of inconvenience in using a stirring device in the prior art.
[0007] In order to solve the above technical problems, the embodiment of the utility model discloses a split type high ductility concrete mixing device, comprising a concrete container and a mixing unit which are separable from each other; wherein the concrete container can contain concrete to be mixed, and a wheel group is arranged at the bottom; the mixing unit comprises: a support assembly and a mixing head assembly, the support assembly comprises a base, a support body erected on the base, and the mixing head assembly comprises a driving component and a mixing head; wherein the driving component is fixedly mounted on the upper end of the support body, the mixing head has a connecting part extending vertically downward, and a mixing part which is arranged below the connecting part and extends downward in a spiral shape, and the upper end of the connecting part is clutch-connected to the driving end of the driving component through a clutch assembly; and a container fixing bracket is also formed at the lower part of the support body, the container fixing bracket extends from the support body toward the side where the mixing head is located, and a separable engaging and connecting component is formed at the corresponding part of the inner peripheral wall of the container fixing bracket and the outer peripheral wall of the concrete container.
[0008] By adopting the above technical solution, during use, the concrete container is first moved to the mixing unit by using the wheel group at the bottom of the concrete container and abutted against the mixing unit, the concrete container is fixed to the bracket body by using the container fixing bracket, and then the mixing head is extended into the concrete container filled with concrete, and the mixing head is driven to rotate by the driving component to mix the concrete inside the concrete container, and finally the concrete container after mixing is pushed to the site for use; this split high-ductility concrete mixing device can improve the concrete mixing efficiency by arranging multiple concrete containers to be used alternately with the mixing unit.
[0009] Furthermore, by configuring the stirring head to have a connecting portion extending vertically downward, and a stirring portion arranged below the connecting portion and extending downward in a spiral shape, compared with the prior art in which a stirring shaft is arranged, and spiral blades or blades of other shapes are arranged on the circumference of the stirring shaft, the stirring head in this scheme has a simple structure and is easy to manufacture.
[0010] Furthermore, during use, the driving component drives the mixing head to rotate, so that the mixing head mixes the concrete in the concrete container. When mixing is completed, the clutch assembly installed between the upper end of the connection part and the driving end of the driving component can release the transmission of the driving component to the mixing head, thereby preventing the mixing head from transmitting force to the driving end of the driving component due to the viscosity of the mixed concrete, causing damage to the driving component. Therefore, this structure can also reduce the influence of external forces on the driving end of the driving component, which is conducive to prolonging the service life of the driving component.
[0011] Furthermore, by arranging a wheel set at the bottom of the concrete container, and forming a joint connection component detachable from the inner circumferential wall of the container fixing bracket at a corresponding position of the outer circumferential wall of the concrete container, compared with the prior art in which the concrete container is fixedly arranged on a plate with a wheel set, and the limiting structure on the plate is detachably connected to the stirring device, the concrete container in this solution has a compact structure and a simple construction, which not only reduces the manufacturing cost, but also facilitates miniaturization for use.
[0012] In summary, the split high-ductility concrete mixing device provided by the utility model simplifies the structure and reduces the cost, and is also more conducive to miniaturization design and easy to use.
[0013] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein the concrete container is a cylindrical structure, including a detachable cylinder body and a cylinder cover; the container fixing bracket includes a plurality of semi-ring brackets arranged at intervals in the vertical direction and extending in the horizontal direction, the inner periphery of each semi-ring bracket is adapted to the outer periphery of the concrete container, and clamping parts are formed on both side ends, and the outer periphery of the cylinder of the concrete container is formed with a corresponding clamped part; and the cylinder cover of the concrete container is formed with a through groove for the connecting part of the mixing head to pass through.
[0014] By adopting the above technical solution, during use, when the mixing head mixes the concrete in the cylinder, the cylinder cover covering the cylinder can prevent sand and gravel in the concrete from splashing during mixing, thereby improving the sealing of the concrete container during the mixing process.
[0015] Furthermore, during use, the cylindrical concrete container can be pushed to one side of the container fixing bracket, and the concrete container can be positioned using a semi-ring bracket whose inner circumference is adapted to the outer circumference of the concrete container, so as to ensure that the mixing head and the concrete container are in relative position before mixing begins, so that the mixing head can be normally extended into the concrete container for mixing. During use, the positioned concrete container is fixed by the clamped portion of the outer circumference of the cylinder and the clamping portion of the end of the semi-ring bracket, so as to improve the stability of the concrete container when the mixing head mixes the concrete in the concrete container. After the concrete is mixed, the clamped portion of the outer circumference of the cylinder and the clamping portion of the end of the semi-ring bracket can be easily released. At this time, the user can remove the concrete container storing concrete, and then move the next concrete container that needs to be mixed to the position with the mixing head, and repeat the above operations in sequence. This process is not only efficient, but also more labor-saving due to the setting of the wheel group.
[0016] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein in a corresponding pair of clamping parts and a clamped part, the clamping part is an elastic protrusion protruding from the end of the semi-ring bracket, and the clamped part is formed as a groove adapted to the shape of the elastic protrusion; or the corresponding pair of clamping parts and the clamped part are a pair of magnetic connecting components.
[0017] By adopting the above technical solution, during use, by setting the clamping part as an elastic protrusion and forming the clamped part as a groove adapted to the shape of the elastic protrusion, when the concrete container is positioned on the semi-ring bracket, the elastic protrusion cooperates with the groove, which not only has a fixing effect, but also has a buffering effect, reducing the collision between the concrete container and the semi-ring bracket during the positioning process, thereby preventing the concrete container from being damaged by collision and impact with the semi-ring bracket.
[0018] Furthermore, during use, by forming the clamping portion and the clamped portion into a pair of magnetic connection components, when the concrete container abuts against the semi-ring bracket, the relative positions of the concrete container and the semi-ring bracket are positioned using the magnetic attraction of the magnetic connection component, thereby preventing the concrete container from shifting during the mixing process, thereby causing abnormalities in the mixing process.
[0019] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein the driving end of the driving component extends vertically downward; the clutch assembly includes a sleeve fixed to the top end of the connecting part, and a mounting hole penetrating the driving end of the driving component, and a fixing hole corresponding to the mounting hole is formed on the side wall of the sleeve, and a fixing bolt is passed through the fixing hole and the mounting hole in sequence, so that the upper end of the connecting part can be detachably connected to the driving end of the driving component.
[0020] With the above technical solution, during the preparation process before mixing, the sleeve fixed to the top of the connection part is first sleeved on the driving end of the driving component, and then the bolts are passed through the fixing hole of the sleeve and the mounting hole of the driving end in sequence to detachably connect the mixing head to the driving component. After mixing is completed, the mixing head and the driving component are released from transmission through the above structure, and the mixing head can rotate freely relative to the driving component, which can reduce the damping force applied by the concrete with high viscosity after mixing to the mixing head during the withdrawal process, and then transmitted to the driving end of the driving component, causing damage to the driving component.
[0021] The embodiment of the utility model further discloses a split type high ductility concrete mixing device, wherein the outer periphery of the sleeve is also sleeved with a fixing clamp ring.
[0022] By adopting the above technical solution, during use, by providing a fixed clamp ring on the outer periphery of the sleeve, the connection reliability between the stirring head and the driving component is further improved.
[0023] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein the driving end of the driving component extends vertically downward; the clutch assembly includes a fixed sleeve fixed to the top end of the connecting part, and a mounting sleeve fixed to the top end of the driving end of the driving component; the opposite end walls of the fixed sleeve and the mounting sleeve are respectively formed with engaging protrusions and engaging recesses that are adapted to each other; wherein when the engaging protrusion is adapted to the engaging recess, the fixed sleeve and the mounting sleeve are engaged in a non-rotatable manner relative to each other.
[0024] With the above technical solution, during use, the fixed sleeve is first sleeved on the installation sleeve by forming mutually matching engagement protrusions and engagement recesses on the opposite end walls of the fixed sleeve and the installation sleeve. Then, the driving end of the driving component drives the installation sleeve to rotate. Since the fixed sleeve and the installation sleeve cannot rotate relative to each other, the installation sleeve drives the fixed sleeve to rotate, thereby rotating the connecting part fixed to the fixed sleeve, thereby realizing the rotational stirring of the concrete by the mixing head. When the stirring is completed, the transmission between the mixing head and the driving component is released through the above structure. At this time, the mixing head can rotate freely relative to the driving component, which can reduce the damping force applied by the concrete with high viscosity after stirring to the mixing head during the withdrawal process, and then transmit it to the driving end of the driving component, causing damage to the driving component.
[0025] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein the engaging protrusion and the engaging recess are respectively formed at the central parts of the opposite end walls of the fixed sleeve and the mounting sleeve; and the engaging protrusion is a protrusion with a long strip, a cross or a polygonal cross section, and the engaging recess is a recess with a matching cross section and a long strip, a cross or a polygonal cross section.
[0026] By adopting the above technical solution, during use, by setting the engaging protrusions and the engaging recesses to be elongated, cross-shaped or polygonal structures, not only the overall structure of the fixed sleeve and the mounting sleeve is simplified and the manufacturing is facilitated, but also the fixed sleeve is easily mounted on the mounting sleeve.
[0027] An embodiment of the utility model also discloses a split-type high-ductility concrete mixing device, wherein a first engaging hole is formed on the side wall of the engaging recess, and a second engaging hole penetrating the engaging protrusion is correspondingly formed; when the engaging protrusion is adapted in the engaging recess, the fixing sleeve and the installation sleeve are fixedly connected together by means of engaging bolts that pass through the first engaging hole and the second engaging hole in sequence.
[0028] By adopting the above technical solution, after the fixing sleeve is sleeved on the installation sleeve, the fixing sleeve and the installation sleeve can be fixed for a second time by passing the joining bolts through the first joining hole of the joining recess and the second joining hole of the joining protrusion in sequence, thereby improving the connection strength between the fixing sleeve and the installation sleeve.
[0029] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, which further includes a lifting mechanism arranged on the bracket body, and a driving component is arranged on the lifting mechanism through a fixed pad, and the lifting mechanism drives the driving component to slide in a vertical direction.
[0030] By adopting the above technical solution, during use, when the mixing head completes mixing the concrete in the concrete container, the lifting mechanism arranged on the bracket body lifts the driving component to separate the mixing head from the concrete container, making it convenient to push the concrete container after mixing to the site for use.
[0031] Furthermore, a lifting mechanism that slides in the vertical direction is provided on the bracket body, which also improves the efficiency of the stirring process and the degree of automation of the lifting and lowering of the stirring head.
[0032] The embodiment of the utility model also discloses a split high-ductility concrete mixing device, wherein the lifting mechanism includes a guide rail arranged on the bracket body in the vertical direction, a slider slidably arranged in the guide rail, and a lifting drive unit that can drive the slider to move along the guide rail; a fixed pad extends in the horizontal direction and one end is fixed to the side wall of the slider; and the lifting drive unit includes a lifting drive motor and a transmission assembly that transmits and connects the output end of the lifting drive motor and the slider; wherein the transmission assembly includes a belt drive assembly or a chain drive assembly.
[0033] By adopting the above technical solution, during use, the lifting drive unit slides along the guide rail arranged on the bracket body with the slider. Since the friction between the slider and the guide rail is smaller than the rolling friction, the slider can provide higher precision and stability. Moreover, the slider is usually made of high-strength material, which can meet the support performance of the slider for the lifting drive unit during the concrete mixing process and withstand the impact force of the mixing head during the mixing process.
[0034] The beneficial effects of the utility model are:

[0066] High ductility concrete is a special type of concrete with excellent performance. Its characteristics can be summarized as follows:
[0067] Good ductility and plasticity: High ductility concrete can undergo large deformations without damage or cracks when subjected to loads, and has good ductility and plasticity. This property makes high ductility concrete have good seismic resistance in extreme environments such as earthquakes.
[0068] High strength and high toughness: High ductility concrete has high strength and high toughness, and its tensile function can reach 200 times that of ordinary concrete. It can effectively prevent the expansion of cracks and improve the strength and ductility of the structure.
[0069] Strong self-healing ability: High ductility concrete has strong self-healing ability, which can improve the durability of components in changing environments.
[0070] Environmental performance: High ductility concrete can be mixed with fly ash instead of cement, which helps reduce fly ash pollution to the air.
[0071] Good construction performance: The cement paste content of high ductility concrete is low, so it has good mixing and construction performance and is easy to construct.
[0072] The following issues need to be paid attention to when mixing this type of concrete:
[0073] Material proportion and water-cement ratio: The water-cement ratio of high ductility concrete is generally not greater than 0.4, and the material proportion needs to meet the engineering requirements.
[0074] Use of admixtures: It is necessary to add appropriate amounts of admixtures such as high-efficiency water reducing agent and retardant to ensure the plasticity and fluidity of concrete.
[0075] Mixing time: Mixing time should generally not be less than 3 minutes to ensure sufficient mixing of the concrete and improve the strength and stability of the concrete.
[0076] Mixing equipment: Special mixing equipment is required, such as a forced concrete mixer or a two-way mixer.
[0077] For a forced concrete mixing device, a mixing blade needs to be installed in the mixing drum, and then materials are added into the mixing drum. Under the strong stirring of the mixing blade, a cross flow is formed to achieve the mixing of the concrete.
[0078] In some solutions, the mixing barrel and the mixing unit are integrated. When the mixing unit finishes mixing the concrete in the mixing barrel, the concrete is taken out through the discharge port provided on the mixing barrel. This device is not convenient for directly pushing the concrete in the mixing barrel to the site for use.
[0079] Furthermore, the mixing barrel is rotatably connected to the support frame of the concrete mixing device, and the mixing assembly is arranged inside the support frame, which leads to a complex overall equipment structure, high manufacturing cost, and is not conducive to miniaturized design. If the equipment needs to be transported to a different environment for use, the equipment support frame needs to be moved as a whole, resulting in greater construction difficulty.
[0080] Therefore, the stirring device in the prior art has the technical problem of being inconvenient to use.
[0081] To solve this problem, the embodiment of the utility model discloses a split high-ductility concrete mixing device, comprising a concrete container and a mixing unit that can be separated from each other. The concrete mixing efficiency can be improved by using a plurality of concrete containers and mixing units in combination. Then, by simplifying the structure of the mixing head, the mixing head is provided with a connecting part extending vertically downward and a mixing part arranged below the connecting part and extending downward in a spiral shape, thereby reducing the manufacturing cost of the mixing head. Then, the mixing head is connected to the driving end of the driving component through a clutch assembly, so that after the mixing is completed, the driving end of the driving component avoids the concrete from generating a force on the driving end of the driving component that is integrally connected to the mixing head, thereby damaging the driving component. Finally, on the basis of not affecting the coordinated mixing between the concrete container and the mixing unit, the structure of the concrete container itself is simplified, so that the concrete container structure is compact and convenient for miniaturization.
[0082] In order to make the purpose, technical solution and advantages of the utility model clearer, the split high-ductility concrete mixing device provided by the utility model will be further described in detail below with reference to the accompanying drawings.
[0083] like Figures 1 to 4As shown, the utility model discloses a split type high ductility concrete mixing device 10, comprising a separable concrete container 100 and a mixing unit 200; wherein the concrete container 100 can contain concrete to be mixed, and a wheel group 110 is arranged at the bottom; the mixing unit 200 comprises: a support assembly 210 and a mixing head assembly 220, wherein the support assembly 210 comprises a base 211, a bracket body 212 erected on the base 211, and the mixing head assembly 220 comprises a driving component 221 and a mixing head 222; wherein the driving component 221 is fixedly mounted on the upper end of the bracket body 212, and the mixing head 222 has a vertical A connecting portion 2221 extending downward, and a stirring portion 2222 arranged below the connecting portion 2221 and extending downward in a spiral shape, the upper end of the connecting portion 2221 is clutch-connected to the driving end 2211 of the driving component 221 through a clutch assembly 230; and a container fixing bracket 2121 is further formed at the lower part of the bracket body 212, the container fixing bracket 2121 extends from the bracket body 212 toward the side where the stirring head 222 is located, and a detachable joint connection component (not shown in the figure) is formed between the inner peripheral wall of the container fixing bracket 2121 and the corresponding portion of the outer peripheral wall of the concrete container 100.
[0084] Specifically, during use, the wheel group 110 at the bottom of the concrete container 100 is first used to move the concrete container 100 to the mixing unit 200 and abut against the mixing unit 200, and the concrete container 100 is fixed to the bracket body 212 through the container fixing bracket 2121, and then the mixing head 222 is extended into the concrete container 100 filled with concrete, and the driving component 221 is used to drive the mixing head 222 to rotate, so as to mix the concrete inside the concrete container 100, and finally the concrete container 100 after mixing is pushed to the site for use; this split high-ductility concrete mixing device 10 can improve the concrete mixing efficiency by arranging a plurality of concrete containers 100 and mixing units 200 for use in combination.
[0085] More specifically, by configuring the stirring head 222 to have a connecting portion 2221 extending vertically downward, and a stirring portion 2222 arranged below the connecting portion 2221 and extending downward in a spiral shape, compared to the prior art in which a stirring shaft is arranged, and spiral blades or blades of other shapes are arranged on the circumference of the stirring shaft, the stirring head 222 in this solution has a simple structure and is easy to manufacture.
[0086] More specifically, during use, the driving component 221 drives the mixing head 222 to rotate, so that the mixing head 222 mixes the concrete in the concrete container 100. After mixing, the clutch assembly 230 installed between the upper end of the connecting portion 2221 and the driving end 2211 of the driving component 221 releases the transmission of the mixing head 222 by the driving component 221, thereby preventing the mixing head 222 from transmitting force to the driving end 2211 of the driving component 221 due to the viscosity of the mixed concrete, thereby damaging the driving component 221. Therefore, the provision of the above-mentioned clutch assembly 230 reduces the influence of external forces on the driving end 2211 of the driving component 221, and prolongs the service life of the driving component 221.
[0087] More specifically, by arranging a wheel set 110 at the bottom of the concrete container 100, and forming a joint connection component that is detachable from the inner circumferential wall of the container fixing bracket 2121 at a corresponding position of the outer circumferential wall of the concrete container 100, compared with the prior art in which the mixing barrel is rotatably arranged in the support frame and is integrally arranged with the mixing device, the split high-ductility concrete mixing device 10 in this solution has a compact structure and a simple construction, which not only reduces the manufacturing cost but also is easy to use.
[0088] The structure of the concrete container 100 will be described in detail below.
[0089] The structure of the concrete container 100 is not limited, and may be a cylindrical structure, a polygonal column structure, or the like.
[0090] In one embodiment, Figure 1 As shown, the concrete container 100 is a cylindrical structure, including a detachable cylinder 101 and a cylinder cover 102, and the cylinder cover 102 is formed with a through groove 1021 for the connection part 2221 of the mixing head 222 to pass through, and a plurality of wheel groups 110 are arranged at the bottom of the cylinder 101; when in use, the cylinder is first moved to the bottom of the mixing head assembly 220 through the plurality of wheel groups 110, and then the cylinder cover 102 with the through groove 1021 is manually lifted and placed above the cylinder 101, when the mixing head 222 mixes the concrete in the cylinder 101, the cylinder cover 102 covering the cylinder 101 prevents the sand and gravel in the concrete from splashing during mixing, thereby improving the sealing of the concrete container 100 during the mixing process.
[0091] It should be noted that the wheel set 110 at the bottom of the concrete container 100 can be set as a universal wheel or a one-way wheel, and the number of the wheel set 110 can be set to 1, 3, 4, etc.
[0092] It should be noted that, in order to facilitate the connection portion 2221 of the stirring head 222 to pass through the through groove 1021 , the through groove 1021 is configured as a strip hole extending to the peripheral side of the cylinder cover 102 , and the connection portion 2221 and the through groove 1021 are clearance-matched.
[0093] It should also be noted that when the cylinder cover 102 is detachably arranged on the cylinder body 101, a handle needs to be provided on the cylinder cover 102 to facilitate personnel to open or close the cylinder cover 102; when the cylinder cover 102 is rotatably arranged on the cylinder body 101 through a hinge (such as Figure 6 As shown in FIG. 1 , not only the concrete container 100 is more compact as a whole, but also the efficiency of personnel opening the cylinder cover 102 is improved.
[0094] In another embodiment, the concrete container 100 is a quadrangular prism structure, including a detachable quadrangular prism barrel body and a barrel cover covering the barrel body, and the barrel cover also has a through groove 1021 for the connecting portion 2221 of the mixing head 222 to pass through.
[0095] It should be noted that, although the concrete container 100 is a quadrangular prism structure, the mixing head 222 can still mix the concrete inside the container 100 .
[0096] In yet another embodiment, Figure 6 As shown, the concrete container 100 is a cylindrical structure, including a cylinder body 101 and a cylinder cover 102. The cylinder cover 102 is configured as two semicircular covers that can be folded and connected to the cylinder body 101. When the two semicircular covers are connected to the cylinder body 101 through hinges and when the two semicircular covers are covered on the cylinder body 101, the through groove 1021 is a through hole formed between the two semicircular covers for the connection part 2221 of the mixing head 222 to pass through.
[0097] The following is a detailed description of the matching modes between the concrete container, the support assembly and the mixing head assembly.
[0098] In one embodiment, Figure 1 and Figure 2 As shown, the container fixing bracket 2121 includes two semi-ring brackets 2121a arranged at intervals in the vertical direction and extending in the horizontal direction. The inner periphery of each semi-ring bracket 2121a is adapted to the outer periphery of the concrete container 100, and clamping parts are formed on both side ends, and the outer periphery of the cylinder 101 of the concrete container 100 is formed with a corresponding clamped part.
[0099] During use, the cylindrical concrete container 100 is pushed to one side of the container fixing bracket 2121, and the concrete container 100 is positioned by using the semi-ring bracket 2121a whose inner circumference matches the outer circumference of the concrete container 100, so as to ensure that the mixing head 222 and the concrete container 100 are in relative position before mixing, so that the mixing head 222 can normally extend into the concrete container 100 for mixing. The positioned concrete container 100 is then fixed by the clamped portion of the outer circumference of its cylinder 101 and the clamping portion of the end of the semi-ring bracket 2121a, so as to improve the stability of the concrete container 100 when the mixing head 222 mixes the concrete in the concrete container 100.
[0100] It should be noted that the container fixing bracket 2121 can not only be set as a semi-ring bracket 2121a, but can also be set to other shapes according to the shape of the concrete container 100, such as a "V"-shaped bracket, a "U"-shaped bracket, etc.
[0101] It should be noted that a plurality of semi-ring brackets 2121a can be arranged at intervals along the vertical direction, specifically, 1, 2, 4, etc. brackets can be arranged.
[0102] In one embodiment, among the corresponding pair of clamping portions (not shown in the figure) and the clamped portions (not shown in the figure), the clamping portions are elastic protrusions protruding from the ends of the semi-ring bracket 2121a, and the clamped portions are formed as grooves adapted to the shape of the elastic protrusions.
[0103] Specifically, during use, by setting the clamping portion as an elastic protrusion and forming the clamped portion as a groove that matches the shape of the elastic protrusion, when the concrete container 100 is positioned on the semi-ring bracket 2121a, the elastic protrusion cooperates with the groove, which not only has a fixing effect, but also has a buffering effect, thereby reducing the collision between the concrete container 100 and the semi-ring bracket 2121a during the positioning process, and improving the service life of the concrete container 100 and the semi-ring bracket 2121a.
[0104] In another embodiment, by configuring the clamping portion and the clamped portion as a pair of magnetic connection components, when the concrete container 100 abuts against the semi-ring bracket 2121a, the relative positions of the concrete container 100 and the semi-ring bracket 2121a are positioned by the magnetic attraction of the magnetic connection component, thereby preventing the concrete container from shifting during the mixing process, thereby preventing abnormal mixing process.
[0105] It should be noted that the magnetic poles of the pair of magnetic connection members are opposite, and the concrete container 100 is fixed on the semi-ring bracket 2121a by the principle of magnetic opposites attracting each other, and the magnetic connection members can be set as permanent magnets, electromagnets, etc.
[0106] The following is a detailed description of the cooperation between the stirring head and the driving component.
[0107] In one embodiment, Figures 2 to 4 As shown, the driving end 2211 of the driving component 221 extends vertically downward; the clutch assembly 230 includes a sleeve 231 fixed to the top of the connecting portion 2221, and a mounting hole (not shown in the figure) penetrating the driving end 2211 of the driving component 221, and a fixing hole (not shown in the figure) corresponding to the mounting hole is formed on the side wall of the sleeve 231, and the fixing bolt 232 passes through the fixing hole and the mounting hole in sequence, so that the upper end of the connecting portion 2221 can be detachably connected to the driving end 2211 of the driving component 221. Then, a fixing snap ring 233 is sleeved on the outer periphery of the sleeve 231.
[0108] Specifically, in the pre-mixing preparation process, the sleeve 231 fixed to the top of the connecting part 2221 is first sleeved on the driving end 2211 of the driving component 221, and then the fixing bolt 232 is sequentially passed through the fixing hole of the sleeve 231 and the mounting hole of the driving end 2211 to detachably connect the mixing head 222 to the driving component 221, and then the fixing clamp 233 is sleeved on the outer periphery of the sleeve 231 and fixed with bolts. After the mixing is completed, the mixing head 222 and the driving component 221 are released from the transmission through the above structure, and the mixing head 222 can rotate freely relative to the driving component 221, which can reduce the damping force applied by the concrete with high viscosity after mixing to the mixing head 222 during the withdrawal process, and then transmitted to the driving end 221 of the driving component 221, causing damage to the driving component 221. By arranging the fixing clamp 233 on the outer periphery of the sleeve 231, the connection reliability between the mixing head 222 and the driving component 221 is further improved.
[0109] In another embodiment, if Figure 2 , Figure 3 and Figure 5 As shown, the driving end 2211 of the driving component 221 extends vertically downward; the clutch assembly 230 includes a fixed sleeve 234 fixed to the top of the connecting portion 2221, and a mounting sleeve 235 fixed to the top of the driving end 2211 of the driving component 221; the opposite end walls of the fixed sleeve 234 and the mounting sleeve 235 are respectively formed with a coupling protrusion 2341 and a coupling recess 2351 that are adapted to each other; wherein when the coupling protrusion 2341 is adapted to be in the coupling recess 2351, the fixed sleeve 234 and the mounting sleeve 235 are non-rotatably coupled to each other.
[0110] Specifically, during use, first, the fixing sleeve 234 is sleeved on the mounting sleeve 235 by forming the engaging protrusions 2341 and the engaging recesses 2351 that fit each other on the opposite end walls of the fixing sleeve 234 and the mounting sleeve 235. Then, after the driving component 211 is powered, the driving end 2211 of the driving component 221 drives the mounting sleeve 235 to rotate. Since the fixing sleeve 234 and the mounting sleeve 235 cannot rotate relative to each other, the mounting sleeve 235 drives the fixing sleeve 234 to rotate, thereby rotating the connecting portion 2221 fixed on the fixing sleeve 234, thereby realizing the rotary mixing of the concrete by the mixing head 222.
[0111] It should be noted that the driving component 211 can be configured as a driving motor, and those skilled in the art can select the model of the driving motor according to actual conditions.
[0112] More specifically, the engaging protrusion 2341 and the engaging recess 2351 are respectively formed at the central parts of the opposite end walls of the fixed sleeve 234 and the mounting sleeve 235; and by setting the cross-sections of the engaging protrusion 2341 and the engaging recess 2351 to be a long strip structure, not only the overall structure of the fixed sleeve 234 and the mounting sleeve 235 is simplified and easy to manufacture, but also it is convenient to put the fixed sleeve 234 on the mounting sleeve 235.
[0113] It should be noted that the cross section of the engaging protrusion 2341 can be set not only as a long strip structure, but also as a cross-shaped or polygonal protrusion, and the cross sections of the engaging recess 2351 and the engaging protrusion 2341 are adapted to each other.
[0114] It should also be noted that the coupling protrusion 2341 and the coupling recess 2351 can also be formed on the periphery of the opposite end walls of the fixed sleeve 234 and the installation sleeve 235, respectively, and a plurality of coupling protrusions 2341 and coupling recesses 2351 are provided in one-to-one correspondence, specifically 1, 3, 4, 8, etc. can be provided.
[0115] In one possible implementation, Figure 5 As shown, a first engaging hole 2352 is formed on the side wall of the engaging recess 2351, and a second engaging hole 2342 penetrating the engaging protrusion 2341 is correspondingly formed on the engaging protrusion 2341; when the engaging protrusion 2341 is adapted in the engaging recess 2351, the fixing sleeve 234 and the mounting sleeve 235 are fixedly connected together by engaging bolts (not shown in the figure) passing through the first engaging hole 2352 and the second engaging hole 2342 in sequence.
[0116] Specifically, during use, after the fixing sleeve 234 is sleeved on the mounting sleeve 235, the fixing sleeve 234 and the mounting sleeve 235 are fixed for a second time by passing the joining bolts through the first joining hole 2352 of the joining recess 2351 and the second joining hole 2342 of the joining protrusion 2341 in sequence, thereby improving the connection strength between the fixing sleeve 234 and the mounting sleeve 235.
[0117] It should be noted that, in one embodiment, in order to improve the mixing efficiency of the mixing head 222 on concrete, the rotation direction of the mixing head 222 driven by the driving component 221 is consistent with the spiral direction of the mixing part 2222 of the mixing head 222 .
[0118] In another embodiment, the rotation direction of the stirring head 222 may be set to be opposite to the spiral direction of the stirring portion 2222 of the stirring head 222 .
[0119] It should be noted that the clutch assembly 230 can also be configured as a flywheel assembly containing a ratchet inside. The driving end 2211 of the driving component 221 is connected to the ratchet, and the end of the connecting part 2221 of the mixing head 222 is connected to the meshing gear. When the driving end 2211 of the driving component 221 rotates clockwise, the ratchet engages with the meshing gear and transmits power to the mixing head 222 to rotate it. When the driving end 2221 of the driving component 221 rotates counterclockwise, the ratchet disengages from the meshing gear, and the power of the driving component 221 cannot be transmitted to the mixing head 222. Through this structure, when the driving end 2211 of the driving component 221 rotates clockwise to drive the mixing head 222 to complete mixing, the mixing head 222 can rotate freely relative to the driving component 221 in the counterclockwise direction, which can reduce the damping force exerted by the concrete with greater viscosity after mixing on the mixing head 222 during the withdrawal process, and then transmit it to the driving end 2211 of the driving component 221, causing damage to the driving component 221.
[0120] The specific structure of the support assembly is described in detail below.
[0121] In one embodiment, Figure 1 and Figure 2 As shown, the support body 212 in the support assembly 210 is not provided with a lifting mechanism, and the driving component 221 is fixed in the vertical direction. Therefore, during use, the mixing head 222 is first placed in the cylinder 101, and then the cylinder 101 is pushed under the driving component 221, and then the mixing head 222 in the cylinder 101 is connected to the driving end 2211 of the driving component 221 via the clutch assembly, and finally the driving component 221 is started to mix the concrete. After the mixing is completed, the mixing head 222 is disassembled from the driving end 2211, and then the mixing head 222 and the mixed concrete in the cylinder 101 are pushed to the site for use.
[0122] In another embodiment, if Figure 6 and Figure 7 As shown, the split high-ductility concrete mixing device 10 further includes a lifting mechanism 300 disposed on the bracket body 212 , and the driving component 221 is disposed on the lifting mechanism 300 through a fixed pad 2122 , and the lifting mechanism 300 drives the driving component 221 to slide in the vertical direction.
[0123] Specifically, during use, when the mixing head 222 completes mixing of the concrete in the concrete container 100, the lifting mechanism 300 disposed on the support body 212 lifts the driving component 221 to separate the mixing head 222 from the concrete container 100, so that the concrete container 100 after mixing is pushed to the site for use.
[0124] More specifically, a lifting mechanism 300 that slides in the vertical direction is provided on the bracket body 212 , which not only improves the stirring efficiency of the split stirring device 10 , but also improves the degree of automation of the lifting and lowering of the stirring head 222 .
[0125] More specifically, the lifting mechanism 300 includes a guide rail 310 arranged on the bracket body 212 in the vertical direction, a slider 320 slidably arranged in the guide rail 310, and a lifting drive unit (not shown in the figure) that can drive the slider 320 to move along the guide rail 310; the fixed pad 2122 extends in the horizontal direction and one end is fixed to the side wall of the slider 320; and the lifting drive unit includes a lifting drive motor, and a transmission component that transmits and connects the output end of the lifting drive motor and the slider 320.
[0126] Specifically, during use, the lifting drive unit slides along the guide rail 310 set on the bracket body 212 with the slider 320. Since the friction between the slider 320 and the guide rail 310 is smaller than the rolling friction, the slider 320 can provide higher precision and stability. Moreover, the slider 320 is usually made of high-strength material, which can meet the support performance of the slider 320 for the lifting drive unit during the concrete mixing process and withstand the impact force of the mixing head 222 during the mixing process.
[0127] It should be noted that the transmission component can not only be set as a transmission component or a chain transmission component, but also can drive the slider 320 to slide by lifting the electric telescopic rod. Specifically, the driving end of the electric telescopic rod can be fixedly connected to the slider, thereby driving the lifting drive motor to lift.
[0128] The embodiment of the utility model also discloses a split high ductility concrete mixing device 10, such as Figure 1 and Figure 2The support assembly 210 also includes a load-bearing block 213, which is fixedly connected to the side of the bracket body 212 away from the mixing head 222 and is located on the base 211. A plurality of wheel groups 110 can also be provided at the bottom of the base 211 to facilitate pushing the mixing unit 200 to the construction site for use.
[0129] The number of the plurality of wheel sets 110 is not limited, and may be 3, 4, 5 or more.
[0130] Specifically, by providing a load-bearing block 213 on one side of the support body 212 , the support assembly 210 is prevented from tipping over, and the split high-ductility concrete mixing device 10 is made more stable during the mixing process.
