Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and in particular relates to a cement mortar mixer. Background Art

[0002] Cement mortar mixer is a kind of machine that mainly mixes cement, standard sand and water in standard proportions and specified time. Its purpose is to prepare specimens for strength testing of cement mortar specimens. Subsequent formed specimens are also required to undergo cement mortar strength tests to test their strength. The strength of the specimens measured is generally directly related to the materials used in the mixing process, the order of adding materials and the control of mixing time.

[0003] The components of new cement-based composite materials are often very complex, including a multi-component combination of cement, sand, water, fly ash, mineral powder, silica fume, fiber, admixtures, activators, early strength agents, accelerators, and other components. These components may have a set order and requirements for addition, and the addition process is relatively cumbersome. Taking magnesium oxysulfide cement-based composite materials as an example, it is necessary to continue to add fly ash and other admixtures or other fillers on the basis of magnesium oxysulfide cement paste. As a ternary cement matrix, the addition order of magnesium oxysulfide cement is as follows: first add magnesium sulfate heptahydrate to the mixing pot, then add warm water to completely dissolve magnesium sulfate heptahydrate (this step is very critical), then add magnesium oxide powder, citric acid and other admixtures to fully stir, and then add powder, fiber, etc. on this basis. As the research and development needs of new cement-based composite materials become more complex, the order and types of addition are becoming more and more abundant, the requirements for feeding accuracy, convenience and controllability are gradually increasing, and new requirements are also put forward for mixers.

[0004] The existing cement mortar (neat slurry) mixer is only equipped with a funnel-shaped feeding inlet, and an extended discharge pipe is arranged below to guide the added material into the mixing pot. However, the bend of the discharge pipe is prone to blockage, resulting in the material not being able to enter the mixing pot in time.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0006] The utility model aims to provide a cement mortar mixer to solve the technical problem that the bent part of the discharge pipe of the existing cement mortar mixer is prone to blockage.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cement mortar mixer comprises a frame, a base is fixedly connected to the bottom of the frame, a support platform is arranged on the top of the base on one side of the frame, a stirring pot is arranged on the support platform, a stirring paddle is arranged on the upper part of the frame, one end of the stirring paddle is rotatably connected to the frame, and the other end extends into the stirring pot for stirring materials, a feeding funnel is arranged on the frame, a discharging channel is connected to the bottom end of the feeding funnel, the discharging channel is bent and extends into the stirring pot, and a paddle unit is rotatably connected to the bent position of the discharging channel for diverting the flow of materials.

[0009] As a further optimized technical solution, the paddle unit includes a driving shaft, both ends of which are rotatably connected to the side walls of the discharge channel, and a plurality of blades are circumferentially arranged on the driving shaft, and the rotation diameter of the blades is smaller than the diameter of the bending position of the discharge channel.

[0010] As a further optimized technical solution, an end of the blade away from the driving shaft is fixedly connected with an elastic extension section, and the rotation diameter of the extension section is larger than the diameter of the bent position of the discharge channel.

[0011] As a further optimized technical solution, the support platform is a hydraulic lifting platform.

[0012] As a further optimized technical solution, a continuous semi-arc texture structure is provided on the inner wall of the feeding funnel, and the texture structure is arranged along the material feeding direction.

[0013] As a further optimized technical solution, a plurality of partitions are evenly arranged in the feeding funnel, and the partitions divide the storage space in the feeding funnel into a plurality of sub-storage spaces of the same volume for storing different ingredients; a baffle plate is rotatably arranged at the bottom of the feeding funnel, and the baffle plate has a feed discharge hole, and the size of the feed discharge hole matches the bottom size of any sub-storage space. When the baffle plate rotates, the feed discharge hole rotates to the position of the sub-storage space where discharge is required, and the ingredients in the sub-storage space flow into the discharge channel through the feed discharge hole.

[0014] As a further optimized technical solution, the baffle plate is connected to a timing control unit for timing control of the rotation of the baffle plate to achieve timed feeding.

[0015] As a further optimized technical solution, the timing control unit includes a timer, a control module, and a driving module.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the present invention.

[0024] In the description of the present invention, the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] The utility model provides a cement mortar mixer, wherein a paddle unit is rotatably connected to the bent position of a material discharging channel, so that the bent position of the material discharging channel is no longer blocked.

[0027] Specific as Figure 1-4 As shown, the cement mortar mixer has a base 2, a frame 1, a support platform 3, a stirring pot 4, a stirring paddle 5, a feeding funnel 6 and a discharge channel 7. One side of the top of the base 2 is fixedly connected to the frame 1, and the other side is fixedly connected to the support platform 3. The stirring pot 4 is installed on the top of the support platform 3, one end of the stirring paddle 5 is rotatably connected to the upper part of the frame 1, and the other end extends into the stirring pot 4 for stirring the material. The feeding funnel 6 is installed on the frame 1 for adding materials, and the discharge channel 7 is arranged below the feeding funnel 6 and connected to the feeding funnel 6. The discharge channel 7 is bent and extended into the stirring pot 4 to guide the materials to be added from the feeding funnel 6 to the stirring pot 4. Among them, a paddle unit 8 is rotatably connected at the bent position of the discharge channel 7 to divert the flow of materials.

[0028] In this embodiment, the paddle unit 8 includes a driving shaft 801, and both ends of the driving shaft 801 are sealed and rotatably connected to the side walls of the discharge channel 7. In addition, the driving shaft 801 is perpendicular to the axis of the discharge channel 7, and one end of the driving shaft 801 is connected to an external motor as a rotation drive source. A plurality of blades 802 are circumferentially arranged on the driving shaft 801, and the blades 802 are semicircular. The rotation diameter of the blades 802 is smaller than the diameter of the bending position of the discharge channel 7, thereby avoiding interference between the blades 802 and the discharge channel 7 during rotation.

[0029] Furthermore, in order to better move the materials and prevent a small amount of materials from adhering to the inner wall of the bent position of the discharge channel 7, an elastic extension section 803 is fixedly connected to one end of the blade 802 away from the driving shaft 801, and the rotation diameter of the extension section 803 is larger than the diameter of the bent position of the discharge channel 7. In this way, the inner wall of the discharge channel 7 is fully scraped by the extension section 803, thereby reducing the probability of the materials adhering to the inner wall of the bent position of the discharge channel 7.

[0030] Furthermore, in order to facilitate the disassembly and cleaning of the stirring pot 4, the support platform 3 is a hydraulic lifting platform.

[0031] Furthermore, in order to reduce the adhesion of the material on the inner wall of the feeding funnel 6, a continuous semi-arc texture structure 601 is provided on the inner wall of the feeding funnel 6, and the texture structure 601 is arranged along the material feeding direction.

[0032] The above technical solution can solve the technical problem that the bend of the discharge pipe on the existing cement mortar mixer is prone to blockage, but there is still a more prominent technical problem in the mixer that needs to be solved urgently.

[0033] The existing mixer feeding method still requires human intervention to be carried out on time and according to the type. The two problems of not being able to feed "on time" and "continuously" will cause time differences and unpredictable human accidents, which will have a certain impact on the mixing of materials and the molding and performance of future specimens, and will also easily lead to non-optimal strength of future specimens. In addition, the existing new cement-based composite materials have complex components, and the manual feeding method is time-consuming and labor-intensive. There are certain errors in manual repetitive operations. The more complicated the feeding process is, the more feeding errors and deviations will be generated.

[0034] In order to solve the technical problem of not being able to add materials on time, six partitions 602 are evenly installed in the material hopper 6. The partitions 602 divide the storage space in the feeding hopper 6 into six sub-storage spaces of equal volume for storing different ingredients; a baffle plate 9 is rotatably arranged at the bottom of the feeding hopper 6, and the baffle plate 9 has a material discharge through hole 901. The size of the material discharge through hole 901 matches the size of the bottom end of any sub-storage space. When the baffle plate 9 rotates, the material discharge through hole 901 rotates to the position of the sub-storage space where the material needs to be discharged, and the ingredients in the sub-storage space flow into the discharge channel 7 through the material discharge through hole 901. The baffle plate 9 is connected to a timing control unit for timing control of the rotation of the baffle plate 9 to achieve timing feeding.

[0035] In this embodiment, a second connecting ring 903 is fixedly connected to the top of the baffle plate 9, and a first connecting ring 902 is fixedly connected to the bottom. The first connecting ring 902 is rotatably connected to the discharge channel 7, and the second connecting ring 903 is rotatably connected to the feeding funnel 6.

[0036] In this embodiment, the timing control unit includes a timer 10, a control module 11, and a driving module 12. The timer 10 is electrically connected to the control module 11, and the control module 11 is electrically connected to the driving module 12. A driving wheel 13 is provided on the driving module 12, and a driven tooth 14 meshing with the driving wheel 13 is provided on the outside of the baffle plate 9. The timer 10 controls the driving module 12 to rotate in a timing manner to drive the baffle plate 9 to rotate in a timing manner to realize timed feeding.

[0037] In this way, when doing experiments, the ingredients to be placed can be placed in the adjacent sub-storage spaces in the order of addition, and the shielding plate 9 can be rotated by the timer 10 to release the ingredients in the corresponding sub-storage spaces in sequence, thereby reducing the experimental error caused by human intervention.

[0038] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
