Description

Technical Field

[0001] This utility model relates to the field of cement performance testing technology, specifically to an automatic liquid addition device and testing system for preparing cement mortar specimens. Background Technology

[0002] In the cement industry, cement mortar strength is used to characterize cement strength. Cement mortar is a viscous mortar made by mixing cement, water and sand in a certain proportion. Currently, in the preparation of cement mortar test specimens, the traditional method is for the operator to use a measuring cup to measure a certain amount of water according to the proportion, add it directly to the mixing pot, add a certain amount of cement and sand, and then use a mixer to mix.

[0003] In existing testing systems, the national standard requires a relatively precise measurement of water weight. GB / T17671-2021, "Test Method for Strength of Cement Mortar (ISO Method)," specifies a water volume of 225 mL ± 1 mL or 225 g ± 1 g. Currently, the conventional procedure involves on-site personnel manually weighing the water in the measuring vessel and then manually pouring it into the mixing pot. This results in low efficiency and reduced testing efficiency. Utility Model Content

[0004] In view of this, the present invention provides an automatic liquid addition device and detection system for preparing cement mortar specimens, in order to solve the problem that the national standard requires a more accurate weight of water, which is currently required by on-site personnel to manually weigh the water in the measuring device and then manually pour it into the mixing pot, resulting in low efficiency and reduced detection efficiency throughout the process.

When the water inlet is in the water pouring position, a stirring pot is suitable to be placed below it, and the liquid in the measuring vessel is suitable to be poured into the stirring pot.

[0010] After the electronic balance accurately weighs the liquid, the grippers drive the measuring instrument to rotate circumferentially, causing the inlet of the measuring instrument to slowly change from the receiving position to the pouring position. Throughout the process, "automatic weighing + automatic pouring" is achieved. The liquid is poured into the mixing pot from the inlet, realizing automated pouring without human intervention. This achieves quantitative and automatic addition of liquid to the mixing pot, avoiding manual operation by on-site personnel. The entire process does not affect the operation of other devices and ensures testing efficiency.

[0011] In one optional embodiment, the rotating assembly further includes a first power component, the first power component and the gripper are respectively disposed on both sides of the first connecting end, and the rotating shaft of the first power component passes through the first connecting end and is connected to the connecting seat of the gripper.

[0015] In one optional embodiment, the water conveying assembly further includes a fixed vertical plate, the fixed vertical plate having a funnel and an overflow pipe on the side facing the water conveyor, the overflow port of the overflow section being higher than the height of the funnel, and the funnel being connected to the overflow pipe.

[0016] In one alternative embodiment, the rotating assembly further includes a base connected to a support arm.

[0017] In one optional embodiment, the rotating assembly further includes a second power component and a rotating shaft. The base includes a first support plate and a bottom plate. The rotating shaft of the second power component passes through the first support plate and is connected to the rotating shaft. The rotating shaft is connected to a second connecting end of the support arm that is opposite to the first connecting end.

[0018] In one optional embodiment, the system further includes a linear module and a sliding seat, wherein the slide rail of the linear module is adapted to the slider portion of the sliding seat, and the second connecting end of the support arm is fixedly mounted on the sliding seat.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] In existing technologies (such as CN208621125U), a water storage container is often used, from which water is transported through a water pipe 703 to a measuring container. A person uses a handheld measuring container to receive the water flowing from the water pipe 703, then uses a control valve or mechanism to cut off the water flow to measure the volume, and finally manually pours the water into the test container. During the test, national standards require extremely high accuracy in water weight measurement. The above process cannot meet the requirements for precise weighing, and the manual water collection and pouring are inefficient.

[0037] The following is combined Figures 1 to 11 The present invention describes embodiments of the present invention. In one aspect, it provides an automatic liquid addition device for preparing cement mortar specimens, comprising:

[0038] Water measuring device 2, water measuring device 2 has a receiving space, the receiving space is suitable for holding liquid;

[0039] Rotating assembly 1 includes a support arm 101 and a gripper 102. The support arm 101 includes a first connecting end 1011, which is connected to the gripper 102.

[0040] An electronic balance 4 is located on one side of the rotating assembly 1. The electronic balance 4 is equipped with a weighing plate 401, on which a water measuring device 2 is placed.

[0041] After the electronic balance 4 accurately weighs the liquid in the water measuring device 2, the jaws 102 clamp the water measuring device 2. The jaws 102 are driven to rotate relative to the first connecting end 1011. The jaws 102 drive the water measuring device 2 to rotate circumferentially, so that the water inlet 204 of the water measuring device 2 slowly changes from the water receiving position to the water pouring position. When the water inlet 204 is in the water pouring position, it is suitable to place the stirring pot 3 below it, and the liquid in the water measuring device 2 is suitable to be poured into the stirring pot 3.

[0042] After the electronic balance 4 accurately weighs the liquid, the gripper 102 drives the measuring device 2 to rotate circumferentially, causing the inlet 204 of the measuring device 2 to slowly change from a receiving position to a pouring position. When the inlet 204 is in the pouring position, a mixing pot 3 is placed underneath, and the liquid is then poured into the mixing pot 3. Throughout this process, "automatic weighing + automatic pouring" is achieved. The liquid is completely poured from the inlet 204 into the mixing pot 3, achieving automated pouring without human intervention. This quantitative and automatic addition of liquid to the mixing pot 3 avoids manual operation by on-site personnel, does not affect the operation of other devices, and ensures testing efficiency. Specifically, the liquid in this embodiment is clean water. In this application, the receiving position of the inlet 204 of the measuring device 2 refers to the inlet 204 being set upwards, and the pouring position of the inlet 204 of the measuring device 2 refers to the position where the measuring device 2 is tilted so that the inlet 204 can flow out.

[0043] Example 1

[0044] In the first implementation, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating assembly 1 also includes a first power component 103. The first power component 103 and the gripper 102 are respectively disposed on both sides of the first connecting end 1011. The rotating shaft of the first power component 103 passes through the first connecting end 1011 and connects to the connecting seat of the gripper 102. Specifically, the first power component 103 is a rotary servo motor. The rotation of the rotating shaft of the first power component 103 drives the connecting seat of the gripper 102 to rotate circumferentially, thereby realizing the circumferential rotation of the gripper 102.

[0045] In one embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating assembly 1 also includes a base 105, which is connected to the support arm 101. The base 105 provides support for the support arm 101, and the base 105 and the support arm 101 are rotatably connected so that the support arm 101 can rotate relative to the base 105.

[0046] In one embodiment, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the rotating assembly 1 also includes a second power component 104 and a rotating shaft 106. The base 105 includes a first support plate 1054 and a base plate 1053. The rotating shaft of the second power component 104 passes through the first support plate 1054 and is connected to the rotating shaft 106. The rotating shaft 106 is connected to the second connecting end 1012 of the support arm 101, which is opposite to the first connecting end 1011. Specifically, the second power component 104 is a rotary servo motor. The rotating shaft of the second power component 104 drives the rotating shaft 106 to rotate, and the rotating shaft 106 then drives the support arm 101 to rotate.

[0047] In this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the base 105 also includes a second support plate 1051 and a third support plate 1052. The second support plate 1051 is located between the first support plate 1054 and the third support plate 1052. The first support plate 1054 and the second support plate 1051, and the second support plate 1051 and the third support plate 1052 are respectively arranged in parallel. The first support plate 1054, the second support plate 1051 and the third support plate 1052 are all fixed on the base plate 1053. The ends of the two ends of the rotating shaft 106 are respectively rotatably connected to the second support plate 1051 and the third support plate 1052. The space between the second support plate 1051 and the third support plate 1052 is used to accommodate the second connecting end 1012 of the support arm 101. It should be noted that the connecting seat of the second power component 104 is fixedly connected to the first support plate 1054, and the connection between the rotating shaft of the second power component 104 and the rotating shaft 106 is located between the first support plate 1054 and the second support plate 1051. The rotating shaft of the second power component 104 and the rotating shaft 106 are fixedly connected by snap-fit ​​or bolt connection.

[0048] In one embodiment, such as Figure 1 , Figure 7 and Figure 8 As shown, the water measuring device 2 includes a conical receiving part 201 and a circular guide part 202. The conical receiving part 201 and the circular guide part 202 are integrally formed. The side of the circular guide part 202 is provided with an overflow part 203. The overflow part 203 includes a connecting section 2031 and an overflow section 2032. The connecting section 2031 is connected to the circular guide part 202. The connecting section 2031 and the overflow section 2032 are hollow. The overflow section 2032 is provided with an overflow port 2033. The overflow port 2033 is used to drain the liquid in the connecting section 2031 and the overflow section 2032. A flow channel is formed by a hollow connecting section 2031 and an overflow section 2032. The end of the overflow section 2032 facing away from the connecting section 2031 is elongated, and the flow channel near the overflow port 2033 is sloped to completely drain the liquid from the overflow section 2032 (i.e., the flow channels of the connecting section 2031 and the overflow section 2032 are free of liquid). This allows the liquid in the measuring vessel 2, when its height is higher than the bottom of the connecting section 2031, to flow sequentially along the connecting section 2031 and the overflow section 2032 to the overflow port 2033, thus ensuring that the weight of the liquid in the measuring vessel 2 meets the requirements and achieving accurate liquid weighing. It should be noted that one end of the circular guide section 202 of the measuring vessel 2 is connected to the conical receiving section 201, and the opening at the other end is the inlet 204. The measuring vessel 2 is made of glass. The overflow section 203 is designed so that when the liquid level exceeds the bottom surface of the connecting section 2031 of the overflow section 203, the liquid will flow out of the measuring device 2 along the overflow section 203, thereby achieving accurate measurement of the liquid inside the measuring device 2. Furthermore, as... Figure 11As shown, the clamping part 1021 of the gripper 102 clamps the outer peripheral surface of the circular guide part 202, and there are two clamping parts 1021, which are located on both sides of the circular guide part 202. The two clamping parts 1021 are driven to clamp or release the water measuring device 2. In this embodiment, there are no specific graduation values ​​on the bottle body of the water measuring device 2.

[0049] In one embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, to facilitate liquid delivery within the vector water conveyor 2, a water delivery assembly 7 is also included. The water delivery assembly 7 is positioned on the same side as the electronic balance 4. The water delivery assembly 7 includes a water delivery platform 701, a telescopic component 702, a fixed horizontal plate 704, and a water delivery pipe 703. The top of the water delivery platform 701 is equipped with the telescopic component 702, the telescopic end of which is connected to the fixed horizontal plate 704. The fixed horizontal plate 704 is equipped with the water delivery pipe 703, the outlet of which corresponds to the inlet 204 of the circular guide section 202, with the outlet height higher than the inlet height. Specifically, the telescopic component 702 is a telescopic cylinder. Driven by the telescopic end of the telescopic component 702, when water needs to be delivered to the water meter 2, the telescopic end extends, causing the water pipe 703 to move above the circular guide section 202 of the water meter 2. In addition, the height of the outlet is higher than the height of the inlet 204, and the liquid flowing out of the outlet of the water pipe 703 enters the water meter 2.

[0050] In one embodiment, such as Figure 4 , Figure 5 , Figure 6 and Figure 10 As shown, the water delivery assembly 7 also includes a fixed vertical plate 705. The fixed vertical plate 705 has a funnel 706 and an overflow pipe 707 on its side facing the water meter 2. The height of the overflow port of the overflow section 203 is higher than the height of the funnel 706. The funnel 706 is connected to the overflow pipe 707, and the overflow pipe 707 is located below the funnel 706. It should be noted that the fixed vertical plate 705 is fixedly connected to the fixed horizontal plate 704, and the fixed vertical plate 705 is located below the fixed horizontal plate 704. When the water meter 2 delivers water, the funnel 706 is exactly below the overflow section 203. When the liquid level in the water meter 2 exceeds the lowest surface of the connecting section 2031 of the overflow section 203, the excess liquid will flow out along the overflow section 203 (the weight of the liquid in the water meter 2 after flowing through the overflow section 203 is the accurate weight), flow into the funnel 706 through the overflow port, and then be discharged through the overflow pipe 707.

[0051] In this embodiment, as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the electronic balance 4 records the weight change of the water measuring vessel 2 during the water filling process. Water filling stops when the increase exceeds 225g from an empty bottle, and excess water flows out through the overflow section 203 of the water measuring vessel 2 into the funnel 706. When calculating the 225g increase from an empty to a full bottle, the deviation of this value from the national standard is recorded remotely. Simultaneously, the weighing plate 401 of the electronic balance 4 can adjust its surface level, thereby fine-tuning the overflow height in the water measuring vessel 2 to precisely control the weight of the water measured in the water measuring vessel 2, conforming to the standard of / T17671-2021 "Test Method for Strength of Cement Mortar - ISO Method". The electronic balance 4 and the mixing pot 3 are respectively located on both sides of the rotating assembly 1. Through the level adjustment of the weighing plate 401 of the electronic balance 4 and the setting of the overflow port, the accuracy of the liquid weight measurement in the water measuring vessel 2 is significantly improved. Furthermore, the electronic balance 4 includes a leveling component connected to the weighing plate 401, which adjusts the levelness of the weighing plate 401. In this embodiment, the leveling component includes a rotating shaft and a knob. The outer peripheral wall of the rotating shaft is connected to a connecting rod below the weighing plate 401. Rotating the knob causes the rotating shaft to change the levelness of the weighing plate 401. Typically, the levelness of the weighing plate 401 and the accuracy of the water measuring device 2 are required to be high, increasing the manufacturing difficulty. However, by setting up the leveling component, fine-tuning of the surface levelness of the symmetrical weighing plate 401 is achieved, reducing the manufacturing difficulty of the weighing plate 401 and the water measuring device 2.

[0052] To achieve automatic control, a controller is also included. The controller is connected to the first power component 103, the second power component 104, the telescopic component 702 and the electronic balance 4 respectively. The controller can also record and verify the measurement data of the electronic balance 4.

[0053] A method for using an automatic liquid addition device for preparing cement mortar specimens includes the following steps:

[0054] (1) The water measuring device 2 is located above the electronic balance 4 in the water receiving position. The water measuring device 2 is an empty bottle. The electronic balance weighs the first weight value of the water measuring device 2 and transmits it to the controller. The controller controls the extension end of the telescopic part 702 to extend so that the outlet of the water supply pipe 703 is above the inlet 204 of the water measuring device 2. At the same time, the funnel 706 is located below the overflow part 203 and delivers liquid into the water measuring device 2. When the liquid level is higher than the overflow part 203, it will flow into the funnel 706. Then, the weighing plate 401 adjusts its own surface level until the liquid level is level with the bottom of the connection section 2031 of the overflow part 203 and the overflow port no longer flows out of the liquid. The electronic balance 4 weighs the second weight value of the water measuring device 2 after the overflow port no longer flows out and transmits it to the controller. The value of the second weight value measured by the electronic balance 4 minus the first weight value is exactly the weight of the liquid to be weighed, that is, the value range is within 225g±1g.

[0055] (2) The second power component 104 drives the support arm 101 to rotate circumferentially around the rotating shaft 106 as the central axis. When the counterclockwise rotation angle reaches 90°, ( Figure 5 As shown, when the water reaches the pouring position, the inlet 204 of the water measuring device 2 is set horizontally. At this time, the inlet 204 of the water measuring device 2 is located above the mixing pot 3, and the liquid slowly begins to flow into the mixing pot 3.

[0056] (3) The first power component 103 drives the gripper 102 to rotate counterclockwise relative to the support arm 101, and after the rotation angle reaches 90°, ( Figure 6 As mentioned above, the inlet 204 of the measuring vessel 2 is vertically downward, so that the liquid in the measuring vessel 2 can completely enter the mixing pot 3;

[0057] (4) After the liquid in the measuring vessel 2 is poured out, the first power component 103 and the second power component 104 rotate clockwise in sequence, and the measuring vessel 2 returns to the top of the electronic balance 4. The clamping part 1021 releases the measuring vessel 2, and the electronic balance 4 weighs the third weight value of the measuring vessel 2 and transmits it to the controller (the controller judges the difference between the first weight value and the third weight value to determine whether the water in the measuring vessel 2 has been completely poured into the mixing pot 3). If the difference is less than 1g, it meets the requirements. If the difference is greater than or equal to 1g (meaning that too many water droplets are attached to the inner wall of the measuring vessel 4), steps (2)-(4) need to be repeated until the difference range between the first weight value and the third weight value is met, and the water addition process ends.

[0058] Example 2

[0059] In the second implementation, such as Figure 2 As shown, the rotating assembly 1 also includes a first power component 103. The first power component 103 and the gripper 102 are respectively disposed on both sides of the first connecting end 1011. The rotating shaft of the first power component 103 passes through the first connecting end 1011 and connects to the connecting seat of the gripper 102. Specifically, the first power component 103 is a rotary servo motor. The rotation of the rotating shaft of the first power component 103 drives the connecting seat of the gripper 102 to rotate circumferentially, thereby realizing the circumferential rotation of the gripper 102.

[0060] In one embodiment, such as Figure 2 As shown, the rotating assembly 1 also includes a sliding seat 107, which is connected to the support arm 101. The second connecting end 1012 of the support arm 101 is fixed on the sliding seat 107, and the sliding seat 107 supports the support arm 101. Figure 2 As shown, the sliding seat 107 is also provided with reinforcing ribs 1071 to further fix and stabilize the support arm 101.

[0061] In one embodiment, such as Figure 2As shown, it also includes a linear module 5. The slide rail of the linear module 5 is adapted to the slider portion 1072 of the sliding seat 107, and the second connecting end 1012 of the support arm 101 is fixedly mounted on the sliding seat 107. The slider portion 1072 is driven to slide by the linear module 5, thereby driving the water meter 2 to move. It should be noted that the linear module 5 is existing technology and is a common structure composed of linear guide rails, ball screws / synchronous belts / gear racks and pinions, drive motors, and aluminum alloy profiles. It converts electrical energy into mechanical energy to achieve the linear reciprocating motion of the load, thereby driving the base 105 to perform reciprocating linear motion.

[0062] In this embodiment, an electronic balance 4 is also included. The electronic balance 4 and the stirring pot 3 are located on both sides of the linear module 5. The structure and function of the electronic balance 4 are exactly the same as in Embodiment 1.

[0063] In this embodiment, the structure of the water meter 2 is exactly the same as that in embodiment 1.

[0064] In this embodiment, a water delivery component 7 is also included. The water delivery component 7 is disposed on the same side as the electronic balance 4, and the structure and function of the water delivery component 7 are exactly the same as those in Embodiment 1.

[0065] To achieve automatic control, a controller is also included. The controller is connected to the first power component 103, the telescopic component 702, the linear module 5 and the electronic balance 4 respectively. The controller can also record and verify the measurement data of the electronic balance 4.

[0066] A method for using an automatic liquid addition device for preparing cement mortar specimens includes the following steps:

[0067] (1) The water measuring device 2 is located above the electronic balance 4 in the water receiving position. The water measuring device 2 is an empty bottle. The electronic balance weighs the first weight value of the water measuring device 2 and transmits it to the controller. The controller controls the extension end of the telescopic part 702 to extend so that the outlet of the water supply pipe 703 is above the inlet 204 of the water measuring device 2. At the same time, the funnel 706 is located below the overflow part 203 and delivers liquid into the water measuring device 2. When the liquid level is higher than the overflow part 203, it will flow into the funnel 706. Then, the weighing plate 401 adjusts its own surface level until the liquid level is level with the bottom of the connection section 2031 of the overflow part 203 and the overflow port no longer flows out of the liquid. The electronic balance 4 weighs the second weight value of the water measuring device 2 after the overflow port no longer flows out and transmits it to the controller. The value of the second weight value measured by the electronic balance 4 minus the first weight value is exactly the weight of the liquid to be weighed, that is, the value range is within 225g±1g.

[0068] (2) The linear module 5 drives the sliding seat 107 to move linearly, which in turn drives the support arm 101 to move, so that the water measuring device 2 is located near the mixing pot 3 and reaches the water pouring position, and the height of the water measuring device 2 is higher than the top of the mixing pot 3.

[0069] (3) The first power component 103 drives the gripper 102 to rotate 180° counterclockwise relative to the support arm 101 (the water inlet 204 of the measuring device 2 slowly changes from vertical upward to vertical downward), so that the water inlet 204 of the measuring device 2 slowly moves to the top of the mixing pot 3, and the liquid in the measuring device 2 flows completely into the mixing pot 3.

[0070] (4) After the liquid in the measuring vessel 2 is poured out, the first power component 103 rotates clockwise, and the measuring vessel 2 returns to the top of the electronic balance 4. The clamping part 1021 releases the measuring vessel 2, and the electronic balance 4 weighs the third weight value of the measuring vessel 2 and transmits it to the controller (the controller judges the difference between the first weight value and the third weight value to determine whether the water in the measuring vessel 2 has been completely poured into the mixing pot 3). If the difference is less than 1g, it meets the requirements. If the difference is greater than or equal to 1g, steps (2)-(4) need to be repeated until the requirements are met, and the water addition process ends.

[0071] Example 3

[0072] In the third implementation, such as Figure 2 As shown, the rotating assembly 1 also includes a first power component 103. The first power component 103 and the gripper 102 are respectively disposed on both sides of the first connecting end 1011. The rotating shaft of the first power component 103 passes through the first connecting end 1011 and connects to the connecting seat of the gripper 102. Specifically, the first power component 103 is a rotary servo motor. The rotation of the rotating shaft of the first power component 103 drives the connecting seat of the gripper 102 to rotate circumferentially, thereby realizing the circumferential rotation of the gripper 102.

[0073] In one embodiment, such as Figure 3 As shown, it also includes a rotating plate 603, and the second connecting end 1012 of the support arm 101 is fixedly mounted on the rotating plate 603. The rotating plate 603 drives the support arm 101 to rotate in the horizontal plane.

[0074] In one embodiment, such as Figure 3 As shown, it also includes a rotating assembly 6, which includes a support frame 601 and a rotating platform 602. The rotating platform 602 is located on the top of the support frame 601, and the rotating end of the rotating platform 602 is fixedly connected to the rotating plate 603. The rotating platform 602 drives the rotating plate 603 to rotate. Specifically, the rotating platform 602 is a rotary servo motor. Through the setting of the rotating platform 602, the rotating platform 602 drives the rotating plate 603, and then the rotating plate 603 drives the support arm 101 to rotate, thereby changing the position of the water measuring device 2.

[0075] In this embodiment, an electronic balance 4 is also included. The electronic balance 4 and the stirring pot 3 are located on both sides of the linear module 5. The structure and function of the electronic balance 4 are exactly the same as in Embodiment 1.

[0076] In this embodiment, the structure of the water meter 2 is exactly the same as that in embodiment 1.

[0077] In this embodiment, a water delivery component 7 is also included. The water delivery component 7 is disposed on the same side as the electronic balance 4, and the structure and function of the water delivery component 7 are exactly the same as those in Embodiment 1.

[0078] A method for using an automatic liquid addition device for preparing cement mortar specimens includes the following steps:

[0079] (1) The water measuring device 2 is located above the electronic balance 4 in the water receiving position. The water measuring device 2 is an empty bottle. The electronic balance weighs the first weight value of the water measuring device 2 and transmits it to the controller. The controller controls the extension end of the telescopic part 702 to extend so that the outlet of the water supply pipe 703 is above the inlet 204 of the water measuring device 2. At the same time, the funnel 706 is located below the overflow part 203 and delivers liquid into the water measuring device 2. When the liquid level is higher than the overflow part 203, it will flow into the funnel 706. Then, the weighing plate 401 adjusts its own surface level until the liquid level is level with the bottom of the connection section 2031 of the overflow part 203 and the overflow port no longer flows out of the liquid. The electronic balance 4 weighs the second weight value of the water measuring device 2 after the overflow port no longer flows out and transmits it to the controller. The value of the second weight value measured by the electronic balance 4 minus the first weight value is exactly the weight of the liquid to be weighed, that is, the value range is within 225g±1g.

[0080] (2) The rotating table 602 drives the rotating plate 603 to rotate clockwise in the horizontal plane. After the measuring water device 2 reaches the edge of the mixing pot 3, it stops rotating and reaches the water pouring position.

[0081] (3) The first power component 103 drives the gripper 102 to rotate 180° counterclockwise relative to the support arm 101 (the water inlet 204 of the measuring device 2 slowly changes from the water receiving position to the water pouring position until the water inlet 204 is completely vertical and downward), so that the water inlet 204 of the measuring device 2 slowly moves to the top of the mixing pot 3, and the liquid in the measuring device 2 flows completely into the mixing pot 3.

[0082] (4) After the liquid in the measuring vessel 2 is poured out, the first power component 103 and the rotating plate 603 rotate counterclockwise in sequence, and the measuring vessel 2 returns to the top of the electronic balance 4. The clamping part 1021 releases the measuring vessel 2, and the electronic balance 4 weighs the third weight value of the measuring vessel 2 and transmits it to the controller (the controller judges the difference between the first weight value and the third weight value to determine whether the water in the measuring vessel 2 has been completely poured into the mixing pot 3). If the difference is less than 1g, it meets the requirements. If the difference is greater than or equal to 1g, steps (2)-(4) need to be repeated until the requirements are met, and the water addition process ends.

[0083] A testing system includes the above-mentioned automatic liquid addition device for preparing cement mortar specimens, and also includes a mixing pot 3, so as to cooperate with the mixing pot 3 and other devices in the system to realize the automation of the entire process.

[0084] The automatic liquid addition device for preparing cement mortar specimens provided by this utility model has the following advantages: (1) After the electronic balance 4 accurately weighs the liquid, the clamp 102 drives the measuring device 2 to rotate circumferentially, so that the inlet 204 of the measuring device 2 slowly turns from upward to downward. In the whole process, "automatic weighing + automatic water pouring + automatic data recording" is realized. The liquid is poured into the mixing pot 3 from the inlet 204 to realize automatic pouring. No human operation is required, and the liquid is added to the mixing pot 3 in a quantitative manner automatically; (2) The automatic liquid addition device is installed on one side of the mixing pot 3 to realize the automatic liquid addition device in the mixing pot 3. (3) Provides different ways of moving the water meter 2 so that users can choose the appropriate solution according to their actual needs; (4) The liquid is accurately weighed by setting the surface level adjustment of the weighing plate 401 of the electronic balance 4 and the overflow part 203. Overweight liquid will flow out along the overflow part 203, so as to realize the accurate weighing of the liquid weight and meet the design requirements of the national standard; (5) The whole device is small in size and occupies limited space. It can replace manual operation and realize automatic and accurate water addition and pouring; (6) The water obtained can be accurately measured to meet the experimental requirements, and the data recorded by the controller can be traced.

[0085] As an alternative implementation method, the liquid may also be pure water, etc.

[0086] As an alternative implementation, the leveling assembly further includes at least three telescopic adjusting rods, each connected to the weighing plate 401. The levelness of the weighing plate 401 is adjusted by adjusting the length of one or two telescopic adjusting rods. The leveling assembly of this application is common knowledge in the art, and any mechanism capable of adjusting the levelness of the weighing plate 401 can be used as a leveling assembly. Alternatively, the levelness of the weighing plate 401 can be ensured by adjusting the levelness of the bottom support portion of the electronic balance 4.

[0087] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
