[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
[0032] The utility model provides a concrete mortar screening device, referring to Figures 1 to 5 The concrete mortar screening device 100 comprises a shaking assembly 1, a screening assembly 2 and a cover assembly 3. The screening assembly 2 is arranged on the shaking assembly 1, and the screening assembly 2 is provided with a sieve cavity (not shown in the figure) with one end being open, and the sieve cavity is used to accommodate concrete mortar, and the cover assembly 3 is used to press the screening assembly 2 and cover the opening of the sieve cavity, and the shaking assembly 1 is used to provide a shaking force for the screening assembly 2, and the screening assembly 2 screens the concrete mortar under the action of the shaking assembly 1.
[0033] Based on the above-mentioned scheme setting, automatic screening of concrete mortar is achieved through the shaking component 1, the screening component 2 and the covering component 3. It has a simple structure and is easy to operate. It can not only greatly reduce the labor intensity of workers and help improve the efficiency of screening concrete mortar, but also the particle uniformity of the screened concrete mortar is good, which greatly improves the screening effect of the concrete mortar, thereby improving the accuracy of the determination of the setting time of the concrete mortar.
[0034] The shaking assembly 1 includes a base 11, a shaking member 12 and a driving member 13. The shaking member 12 is mounted on the base 11. The screening assembly 2 is detachably connected to the shaking member 12. The driving member 13 is in transmission cooperation with the shaking member 12. The driving member 13 is used to drive the screening assembly 2 to work through the shaking member 12. Such an arrangement can realize the electric drive of the screening assembly 2 to work, so as to replace manual work, with sufficient power and high speed, which can not only well improve the screening efficiency of the screening concrete mortar, but also ensure the particle uniformity of the screening concrete mortar.
[0035] It is understandable that the driving member 13 can cooperate with the rocking member 12 through a cam structure or a crank rocker structure to drive the rocking member 12 to swing back and forth or vibrate, so that the rocking member 12 can drive the screening assembly 2 to work, so as to facilitate the screening of concrete mortar.
[0036] The rocking member 12 may be a rocking frame or a rocking base, or may be other structural members having rocking and supporting functions, which will not be described in detail herein.
[0037] The driving member 13 may be a motor or other structural member capable of driving the shaking member 12 to shake, and is not specifically limited thereto.
[0038] Reference Figures 1 to 5 The sealing assembly 3 includes a bracket 31 and a pressure cover 32. The bracket 31 is connected to the shaking assembly 1, that is, the bracket 31 is connected to the shaking member 12. The pressure cover 32 has a connecting portion 321 and a sealing portion 322. The connecting portion 321 is detachably connected to the bracket 31. The bracket 31 is used to support the pressure cover 32. The pressure cover 32 seals the opening of the sieve cavity through the sealing portion 322 and presses the sieve assembly 2.
[0039] With such arrangement, on the one hand, the pressure cover 32 can well hold the screening component 2, so that the screening component 2 can stably screen the concrete mortar, which helps to improve the quality of the screened concrete; on the other hand, the sealing portion 322 blocks the opening of the screen cavity, effectively preventing concrete mortar from splashing out of the opening of the screen cavity during the screening process, thereby ensuring the reliability of the screening of the concrete mortar.
[0040] Among them, the bracket 31 can be composed of multiple vertical rods and trusses, and the number of connecting parts 321 is set to be multiple. The multiple connecting parts 321 are sleeved and connected with the corresponding vertical rods and fixed by bolts. This not only enables the pressure cover 32 to move along the direction specified by the vertical rods, but also can fix the pressure cover 32 well, so that the pressure cover 32 can stably press the screening assembly 2.
[0041] Continue to refer to Figures 1 to 5In some embodiments, the screening component 2 includes a barrel 21, a first screening component 22, and a second screening component 23. The barrel 21 is formed with a screening cavity, the first screening component 22 and the second screening component 23 are arranged at intervals and are both connected to the barrel 21, the first screening component 22 is arranged above the second screening component 23, the first screening component 22 is penetrated by a plurality of through-ports 221, the second screening component 23 is penetrated by a plurality of sieve openings 231, and the plurality of through-ports 221 and the plurality of sieve openings 231 are both used for screening concrete mortar.
[0042] With such arrangement, screening is performed in a double-layer structure, that is, the concrete mortar is screened by the first screening element 22 and the second screening element 23, which effectively improves the effect of screening the concrete mortar and makes the particles of the concrete mortar more uniform.
[0043] The caliber of the sieve opening 231 is smaller than the caliber of the through opening 221. For example, the caliber of the through opening 221 may be 5 mm, and the caliber of the sieve opening 231 may be 4.75 mm. Aggregate mortar with a particle size greater than 5 mm can be screened out through the multiple through openings 221 of the first screening member 22, and aggregate mortar with a particle size greater than 4.75 mm can be screened out through the multiple sieve openings 231 of the second screening member 23. In this way, on the one hand, the possibility of the sieve opening 231 of the first screening member 22 being blocked can be effectively reduced, and on the other hand, the concrete mortar can be well screened, so that the particles of the screened concrete mortar are more uniform.
[0044] The first screening member 22 and the second screening member 23 are both arranged at the middle position of the barrel member 21 along its own length direction. Such arrangement can reasonably divide the space of the sieve cavity, so that there can be sufficient space above the first screening member 22 to accommodate the concrete mortar put in, and at the same time, there is also sufficient space below the first screening member 22 to accommodate the screened concrete mortar, thereby meeting the needs of screening processing and usage requirements, and effectively improving the performance of the concrete mortar screening device 100.
[0045] It is understandable that the first screening element 22 and the second screening element 23 may be screens or other structural elements with screening functions, as long as they can screen the concrete mortar, and are not specifically limited herein.
[0046] Continue to refer to Figures 1 to 5The barrel member 21 includes a screen barrel 211, and the screen barrel 211 is mounted on the shaking member 12. A screen cavity is formed in the screen barrel 211, and the first screening member 22 and the second screening member 23 are both arranged in the screen cavity and are both detachably connected to the inner wall of the screen barrel 211. Specifically, the peripheral side walls of the first screening member 22 and the second screening member 23 can be fixedly connected to the inner wall of the screen barrel 211 by bolts, so that the first screening member 22 and the second screening member 23 can be stably fixed in the screen barrel 211, so as to improve the screening stability of the concrete mortar device.
[0047] The outer wall of the sieve barrel 211 may be provided with a discharge port (not shown in the figure), which is arranged near the bottom of the sieve barrel 211, and the discharge port is used to discharge the screened concrete mortar. The barrel 21 may also include a movable baffle (not shown in the figure), which is connected to the sieve barrel 211 and is used to close or open the discharge port. In this way, the discharge port can be opened by the movable baffle after the concrete mortar is screened, so that the screened concrete mortar can be discharged, which is convenient to operate and simple to use.
[0048] It is understandable that the movable baffle and the screen barrel 211 may be connected by plug connection, snap connection or fixed connection by screws, etc.
[0049] The inner wall of the screen barrel 211 is provided with a first support portion and a second support portion, wherein the first support portion is used to support the first screening member 22, and the second support portion is used to support the second screening member 23. Such an arrangement enables the first screening member 22 and the second screening member 23 to stably screen the concrete mortar, effectively avoiding the possibility of the first screening member 22 and the second screening member 23 shaking and causing the screening effect to decrease.
[0050] The first support part and the second support part can be screws or steel blocks welded to the inner wall of the screen barrel 211, or can be other supporting structural parts. As long as they can stably support the first screening element 22 and the second screening element 23, no specific limitation is made here.
[0051] Continue to refer to Figures 1 to 5 In other embodiments, the barrel 21 includes a sample barrel 212, a first set 213, and a second set 214. The sample barrel 212, the first set 213, the second screening element 23, the first screening element 22, and the second set 214 are sequentially buckled and connected, and are stacked in sequence from bottom to top, and the sample barrel 212, the first set 213, and the second set 214 enclose a sieve cavity. The sample barrel 212 is installed on the shaking member 12, and the sample barrel 212 is used to collect the concrete mortar screened by the second screening element 23.
[0052] The first set 213 includes at least one first barrel, at least one end of which is abutted and connected to the sample barrel 212, and the other end of which is abutted and connected to the circumferential edge of the second sieve 23. The second set 214 includes at least one second barrel, at least one end of which is abutted and connected to the circumferential edge of the first sieve 22.
[0053] Based on the above-mentioned scheme, the number of the first set of barrels and the second set of barrels can be flexibly increased or decreased according to the screening demand, so as to increase or decrease the capacity of the sieve cavity to meet the demand for a single dose of concrete mortar, thereby greatly improving the use flexibility of the concrete mortar screening device 100 and improving its performance.
[0054] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
