Technical Field

[0001] The present invention relates to the technical field of mortar detection, and specifically relates to a ready-mixed mortar consistency detection device. Background Technique

[0002] The ready-mixed mortar consistency detection device is used to measure the consistency of ready-mixed mortar, and this parameter is crucial for the construction performance and final quality of the mortar.

[0003] The patent with the patent announcement number CN216144652U relates to a ready-mixed mortar consistency detection device, including a bottom plate. One end of the outer wall of the top of the bottom plate is provided with a first column, a working plate is arranged in the middle of the bottom plate, and a second column is arranged on one side of the working plate on the outer wall of the top of the bottom plate; a consistency detection component, the consistency detection component includes a fixed seat, a sliding ruler and a consistency detection cone. One side outer wall of the fixed seat is fixedly connected to the outer wall of the first column, and the top end of the consistency detection cone is fixed to the bottom outer wall of the sliding ruler. This patent can detect two data items, namely the viscosity and consistency of the mortar, through one device. Through one sample detection, two index detections can be effectively carried out on one sample, effectively ensuring that the strength and fluidity of the mortar under the same ratio are both available, and it is better applied in construction.

[0004] In the above patent, through one sample detection, two index detections can be effectively carried out on one sample, effectively ensuring that the strength and fluidity of the mortar under the same ratio are both available, and it is better applied in construction. However, when the device is working, it may be accidentally touched by the staff, resulting in the detection cone being released when the mortar bucket is not properly placed, thereby causing harm to the staff and affecting the subsequent detection accuracy. Therefore, a ready-mixed mortar consistency detection device with a limiting function is designed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a ready-mixed mortar consistency detection device, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A pre-mixed mortar consistency detection device, including a workbench and a conical hammer, includes a limiting device. A placement groove is formed on the surface of the workbench, and a measuring frame is fixedly installed on the surface of the workbench. A motor is fixedly installed on the top of the workbench. The limiting device includes a mortar bucket, a fixing plate, a sliding plate, an L-shaped plate, a clamping rod, a handle, and a limiting disc. The mortar bucket is slidably installed on the inner wall of the placement groove. The fixing plate is fixedly installed on the surface of the workbench. The sliding plate slidably penetrates the surface of the fixing plate. The L-shaped plate slidably penetrates the surface of the workbench. The clamping rod slidably penetrates the surface of the workbench. The handle is fixedly installed at one end of the clamping rod away from the conical hammer. The limiting disc is fixedly installed on the circumferential surface of the conical hammer, which can prevent the staff from pulling the handle when the mortar bucket is not aligned or the equipment is not fully prepared, thus causing unnecessary negative impacts on the staff or the equipment.

[0007] According to the above technical solution, a first telescopic spring rod is fixedly installed on the top of the workbench. The L-shaped plate is fixedly connected to the free end of the first telescopic spring rod. One end surface of the sliding plate close to the L-shaped plate is provided with a first inclined surface. One end surface of the L-shaped plate close to the sliding plate is provided with a second inclined surface. This limit can reduce the downtime caused by accidents and improve its detection efficiency.

[0008] According to the above technical solution, a first clamping groove is formed on the circumferential surface of the clamping rod, and a through groove is formed on the top of the workbench, reducing the influence caused by misoperation.

[0009] According to the above technical solution, it includes a cleaning device and a drying device. The cleaning device includes a sliding plate, a fixing ring, a second telescopic spring rod, a sliding ring, an inclined plate, a linkage block, a water gun, a first water pipe, a water tank, and a second water pipe. The sliding plate is slidably installed at the bottom of the workbench. The fixing ring is fixedly installed on the circumferential surface of the measuring frame. The second telescopic spring rod is fixedly installed on the top of the fixing ring. The sliding plate is fixedly installed at one end of the second telescopic spring rod away from the fixing ring. The inclined plate is fixedly installed on the top of the sliding ring. The linkage block is fixedly installed on the top of the fixing ring. The water gun is rotatably installed inside the linkage block. The first water pipe is fixedly connected between the water gun and the fixing ring. The water tank is fixedly installed on the top of the workbench. A second water pipe is fixedly connected between the water tank and the fixing ring. By regularly cleaning the mortar residues on the conical hammer, it can ensure that the surface of the conical hammer is clean during each detection, avoid affecting the consistency test results, and improve the accuracy and consistency of the test.

[0010] According to the above technical solution, one end of the sliding plate close to the inclined plate is provided with a third inclined surface. A water delivery pipeline is arranged inside the fixing ring. The first water pipe is communicated with the water delivery pipeline. Cleaning can remove the attached mortar, reduce the wear and corrosion caused by hardened substances, and thus extend the service life of the conical hammer and other related components.

[0011] According to the above technical solution, a first sliding groove is formed on the surface of the sliding ring, and a first circular groove is formed at the top of the sliding ring. The spraying and cleaning by rotation adjustment can be carried out better to clean the mortar that is difficult to clean.

[0012] According to the above technical solution, the drying device includes a rotating ring, an air pipe, a pump air box, a reciprocating lead screw, a tooth block, a gear and a jet head. The rotating ring is rotatably installed on the inner wall surface of the sliding ring. The air pipe is fixedly penetrated through the top of the rotating ring. The pump air box is fixedly installed on the surface of the workbench. The reciprocating lead screw is rotatably installed on the inner wall of the first circular groove. The first tooth block is fixedly installed on the circumferential surface of the reciprocating lead screw. The gear is fixedly installed on the circumferential surface of the rotating ring. The jet head is fixedly installed on the inner wall of the rotating ring. After the water spraying treatment, the cone hammer will remain wet, and the wet cone hammer may affect the result of the viscosity test. Through drying, it can effectively prevent the wet cone hammer from being rusted, thereby increasing the friction force during the free fall process, resulting in inaccurate detection.

[0013] According to the above technical solution, an air delivery groove is arranged on the inner wall of the rotating ring. The air pipe is fixedly installed at the air outlet of the pump air box. The tooth block and the gear are meshed with each other. By rotating the jet, the drying effect can be better realized. Drying the cone hammer can reduce the rust generated by the cone hammer due to moisture, thereby prolonging its service life and reducing the replacement frequency.

[0014] The present invention provides a ready-mixed mortar viscosity detection device, which has the following beneficial effects: (1) For the ready-mixed mortar viscosity detection device, when the staff puts the mortar bucket into the placement groove and slides the mortar bucket towards the slide plate, the mortar bucket contacts and presses the slide plate to move towards the L-shaped plate. When the L-shaped plate moves upward under the action of the slide plate and disengages from the first clamping groove to release the limit on the clamping rod, this limit can prevent the staff from pulling the handle when the mortar bucket is not aligned or the equipment is not fully prepared, thus causing unnecessary negative impacts on the staff or the equipment. When the limit disk contacts and presses the clamping rod, the clamping rod moves away from the cone hammer under the action of the limit disk, and then the limit disk is clamped into the clamping rod. This limit can reduce the downtime caused by accidents and improve the detection efficiency.

[0015] (2) For this ready-mixed mortar consistency detection device, the water tank transports water into the inside of the fixed ring through the second water pipe. Subsequently, the water inside the fixed ring is pumped into the inside of the water gun through the first water pipe, and the water is sprayed onto the surface of the conical hammer to clean the impurities and mortar adhering to its surface. When the conical hammer moves to contact and squeeze the sliding plate, the sliding plate moves under the action of the conical hammer on it, and the second telescopic spring rod restores and drives the sliding ring to move upward. When the water gun loses the effect of the sliding ring, the water gun rotates upward. By regularly cleaning the mortar residue on the conical hammer, it can ensure that the surface of the conical hammer is clean every time of detection, avoid affecting the consistency test result, improve the accuracy and consistency of the test, and the cleaning can remove the adhering mortar, reducing the wear and corrosion caused by hardened substances.

[0016] (3) For this ready-mixed mortar consistency detection device, the sliding ring is threadedly connected to the reciprocating lead screw. When the sliding ring moves up and down, it drives the reciprocating lead screw to rotate. Since the tooth block and the gear mesh with each other, when the reciprocating lead screw rotates, it drives the tooth block to rotate, and at the same time, the rotation of the tooth block drives the gear to rotate. The high-pressure gas is rotated and sprayed onto the conical hammer through the air jet head, realizing the drying treatment of the conical hammer. The conical hammer will remain wet after the water spraying treatment, and the wet conical hammer may affect the result of the consistency test. Through drying, it can effectively avoid the corrosion of the wet conical hammer, and then increase the friction force during the free fall process, resulting in inaccurate detection. By rotating the air jet, a better drying effect can be achieved. Description of the Drawings

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 9 , an embodiment of the present invention is: A premixed mortar consistency detection device includes a workbench 1 and a conical hammer 5, and includes a limiting device. A placement groove 2 is opened on the surface of the workbench 1, a measuring frame 3 is fixedly installed on the surface of the workbench 1, a motor 4 is fixedly installed on the top of the workbench 1. The limiting device includes a mortar bucket 61, a fixing plate 62, a sliding plate 63, an L-shaped plate 64, a clamping rod 66, a handle 67 and a limiting disc 68. The mortar bucket 61 is slidably installed on the inner wall of the placement groove 2, the fixing plate 62 is fixedly installed on the surface of the workbench 1, the sliding plate 63 slidably penetrates the surface of the fixing plate 62, the L-shaped plate 64 slidably penetrates the surface of the workbench 1, the clamping rod 66 slidably penetrates the surface of the workbench 1, the handle 67 is fixedly installed at one end of the clamping rod 66 away from the conical hammer 5, the limiting disc 68 is fixedly installed on the circumferential surface of the conical hammer 5. The movement of the conical hammer 5 drives the limiting disc 68 to move. When the limiting disc 68 contacts and presses the clamping rod 66, the clamping rod 66 moves away from the conical hammer 5 under the action of the limiting disc 68, and then the limiting disc 68 is stuck into the clamping rod 66.

[0021] A first telescopic spring rod 65 is fixedly installed on the top of the workbench 1. The L-shaped plate 64 is fixedly connected to the free end of the first telescopic spring rod 65. One end surface of the sliding plate 63 close to the L-shaped plate 64 is set as a first inclined surface, and one end surface of the L-shaped plate 64 close to the sliding plate 63 is set as a second inclined surface. The movement of the sliding plate 63 contacts and presses the L-shaped plate 64 to move upward. When the L-shaped plate 64 moves upward under the action of the sliding plate 63 and disengages from the first clamping groove, the limit on the clamping rod 66 is released.

[0022] A first clamping groove is formed on the circumferential surface of the clamping rod 66. A through groove is formed at the top of the workbench 1. The movement of the handle 67 drives the clamping rod 66 to move, and the movement of the clamping rod 66 releases the limit on the conical hammer 5, and then the conical hammer 5 falls freely.

[0023] During the operation of this embodiment: When the staff places the mortar bucket 61 into the placement groove 2 and slides the mortar bucket 61 towards the sliding plate 63, the mortar bucket 61 contacts and presses the sliding plate 63 to move towards the L-shaped plate 64. At the same time, the movement of the sliding plate 63 contacts and presses the L-shaped plate 64 to move upward. When the L-shaped plate 64 moves upward under the action of the sliding plate 63 and disengages from the first clamping groove to release the limit on the clamping rod 66, this limit can prevent the staff from pulling the handle 67 when the mortar bucket 61 is not aligned or the equipment is not fully prepared, thus causing unnecessary negative impacts on the staff or the equipment. Subsequently, the staff pulls the handle 67 to move away from the conical hammer 5. The movement of the handle 67 drives the clamping rod 66 to move, and the movement of the clamping rod 66 releases the limit on the conical hammer 5. Then the conical hammer 5 falls freely until it falls into the interior of the mortar bucket 61 and hits the mortar inside the mortar bucket 61. Wait for about fifteen seconds, and the measuring frame 3 records the measurement data of this time. When the output end of the motor 4 moves upward, it drives the conical hammer 5 to move upward. At the same time, the movement of the conical hammer 5 drives the limit disk 68 to move. When the limit disk 68 contacts and presses the clamping rod 66, the clamping rod 66 moves away from the conical hammer 5 under the action of the limit disk 68. Subsequently, the limit disk 68 is clamped into the clamping rod 66. This limit can reduce the downtime caused by accidents and improve the detection efficiency.

[0024] Please refer to Figures 1 - 9 On the basis of the above embodiment, in another embodiment of the present invention, it includes a cleaning device and a drying device. The cleaning device includes a sliding plate 71, a fixed ring 72, a second telescopic elastic rod 73, a sliding ring 74, an inclined plate 75, a linkage block 76, a water gun 77, a first water pipe 78, a water tank 79 and a second water pipe 710. The sliding plate 71 is slidably installed on the surface of the workbench 1. The fixed ring 72 is fixedly installed on the circumferential surface of the measuring frame 3. The second telescopic elastic rod 73 is fixedly installed on the top of the fixed ring 72. The sliding plate 74 is fixedly installed at the end of the second telescopic elastic rod 73 away from the fixed ring 72. The inclined plate 75 is fixedly installed on the top of the sliding ring 74. The linkage block 76 is fixedly installed on the top of the fixed ring 72. The water gun 77 is rotatably installed inside the linkage block 76. The first water pipe 78 is fixedly connected between the water gun 77 and the fixed ring 72. The water tank 79 is fixedly installed on the top of the workbench 1. A second water pipe 710 is fixedly connected between the water tank 79 and the fixed ring 72. The water tank 79 transports water into the fixed ring 72 through the second water pipe 710. Subsequently, the water inside the fixed ring 72 is pumped into the water gun 77 through the first water pipe 78 and sprayed onto the surface of the conical hammer 5.

[0025] One end of the sliding plate 71 close to the inclined plate 75 is provided with an inclined surface three. A water delivery pipe is arranged inside the fixed ring 72. The water pipe one 78 is communicated with the water delivery pipe. Under the action of its sliding ring 74, the water gun 77 rotates downward, realizing multi-directional cleaning.

[0026] A sliding groove one is opened on the surface of the sliding ring 71, and a circular groove one is opened on the top of the sliding ring 74. The movement of the sliding plate 71 releases and presses the inclined plate 75 to move towards the fixed ring 72, and the movement of the inclined plate 75 drives the sliding ring 74 to move downward.

[0027] The drying device includes a rotating ring 81, an air pipe 82, a pump air box 83, a reciprocating lead screw 84, a tooth block 85, a gear 86 and a jet head 87. The rotating ring 81 is rotatably installed on the inner wall surface of the sliding ring 74. The air pipe 82 is fixedly penetrated through the top of the rotating ring 81. The pump air box 83 is fixedly installed on the surface of the workbench 1. The reciprocating lead screw 84 is rotatably installed on the inner wall of the circular groove one. The tooth block one 85 is fixedly installed on the circumferential surface of the reciprocating lead screw 84. The gear 86 is fixedly installed on the circumferential surface of the rotating ring 81. The jet head 87 is fixedly installed on the inner wall of the rotating ring 81. The rotation of the tooth block 85 drives the gear 86 to rotate, and the rotation of the gear 86 drives the rotating ring 81 to rotate. At the same time, the pump air box 83 pumps high-pressure gas into the rotating ring 81 through the air pipe 82, and the high-pressure gas is sprayed towards the conical hammer 5 by the jet head 87 in a rotating manner.

[0028] An air delivery groove is arranged on the inner wall of the rotating ring 81. The air pipe 82 is fixedly installed at the air outlet of the pump air box 83. The tooth block 85 and the gear 86 are meshed with each other. When the reciprocating lead screw 84 rotates, it drives the tooth block 85 to rotate, and at the same time, the rotation of the tooth block 85 drives the gear 86 to rotate.

[0029] During the operation of this embodiment: When the conical hammer 5 moves upward to reset, at this time, the water tank 79 transports water into the inside of the fixed ring 72 through the second water pipe 710. Subsequently, the water inside the fixed ring 72 is pumped into the water gun 77 through the first water pipe 78, and the water is sprayed onto the surface of the conical hammer 5 to clean the impurities and mortar attached to its surface. When the conical hammer 5 moves to contact and squeeze the sliding plate 71, the sliding plate 71 moves away from the conical hammer 5 under the action of the conical hammer 5. At the same time, the movement of the sliding plate 71 releases and squeezes the inclined plate 75 to move towards the fixed ring 72. The movement of the inclined plate 75 drives the sliding ring 74 to move downward. Subsequently, the sliding ring 74 approaches and squeezes the inclined surface at the top of the water gun 77. At the same time, the water gun 77 is rotatably connected to the linkage block 76. Under the action of the sliding ring 74, the water gun 77 rotates downward, realizing multi-directional cleaning. Subsequently, the second telescopic spring rod 73 restores and drives the sliding ring 74 to move upward. When the water gun 77 loses the action of the sliding ring 74, the water gun 77 rotates upward. By regularly cleaning the mortar residue on the conical hammer 5, it can ensure that the surface of the conical hammer 5 is clean during each test, avoid affecting the viscosity test results, improve the accuracy and consistency of the test, and the cleaning can remove the attached mortar, reduce the wear and corrosion caused by hardened substances, thereby extending the service life of the conical hammer 5 and other related components, and the rotating and adjustable water spraying cleaning can better carry out the cleaning and clean the difficult-to-clean mortar.

[0030] Since the sliding ring 74 is threadedly connected to the reciprocating lead screw 84, when the sliding ring 74 moves up and down, it drives the reciprocating lead screw 84 to rotate. Since the tooth block 85 meshes with the gear 86, the reciprocating lead screw 84 drives the tooth block 85 to rotate when it rotates. At the same time, the rotation of the tooth block 85 drives the gear 86 to rotate, and the rotation of the gear 86 drives the rotating ring 81 to rotate. At the same time, the air pumping box 83 pumps high-pressure gas into the inside of the rotating ring 81 through the air pipe 82, and the high-pressure gas is rotated and sprayed onto the conical hammer 5 through the air jet head 87, realizing the drying treatment of the conical hammer 5. The conical hammer 5 after the water spraying treatment will remain wet, and the wet conical hammer 5 may affect the result of the viscosity test. Through drying, it can ensure that the moisture on the surface of the conical hammer 5 is removed during each test, so as to obtain more accurate and reliable test data. Through rotating air jetting, a better drying effect can be achieved. Drying the conical hammer 5 can reduce the rusting of the conical hammer 5 caused by moisture, thereby extending its service life and reducing the replacement frequency.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
