Description

Technical Field

[0001] This utility model belongs to the field of mortar technology, and in particular relates to a mortar water retention testing device. Background Technology

[0002] Mortar is a material commonly used in construction and decoration projects. It is mainly used to bond, fill and smooth building components. It is usually composed of cement (or other adhesives), sand (or other fine aggregates) and water, mixed in a certain proportion.

[0003] According to a published method for testing the water retention of gypsum mortar (publication number: CN110954682B), the method includes: determining the composition of the gypsum mortar; preparing two samples with water-retaining agent dosages of 0.2% and 0.3%; testing and calculating the samples after mixing; preparing an aerated block; marking a 200mm gap on the surface of the block with a marker after laying it flat; placing iron blocks of different heights along the left and right edges of the gap; spreading the mixed gypsum mortar sample material between the two iron blocks; scraping it into a sloping shape with a scraper, ensuring that the left and right sides of the material are at the same height as the two iron blocks; curing it at room temperature; and obtaining the minimum thickness of the water-retaining portion of the gypsum mortar after it has completely hardened. However, the above device, with the cooperation of components such as iron blocks, makes it difficult to achieve a uniform mixing effect of the mortar, making it difficult to effectively ensure the uniform distribution of cement, sand, and water in the mortar, and making it difficult to avoid unstable mortar quality due to uneven mixing. This method needs improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a mortar water retention testing device. The force of the rotating rod driven by the motor cooperates with the mixing plate, rack ring, and gear components in the mixing device. This achieves the function of rotating the shaft to drive the gear to rotate, causing the gear to mesh with the rack ring and generate rotation, which in turn drives the shaft to rotate, which in turn drives the rotating rod to rotate, and finally the rotating rod drives the mixing plate to rotate. This solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a mortar water retention testing device, including a mixing tank, a support leg fixedly connected to the bottom of the mixing tank, a storage box provided at the bottom of the mixing tank, and a scale fixedly connected to the side of the storage box.

[0007] The mixing tank is equipped with a stirring device, which includes a support plate fixedly connected to the top of the mixing tank. A motor is fixedly connected to the bottom of the support plate. A rotating rod is fixedly connected to the output shaft of the motor. A rotating rod is rotatably connected to the circumferential surface of the rotating rod. A stirring plate is fixedly connected to the circumferential surface of the rotating rod. A rotating shaft is fixedly connected to one end of the rotating rod. A gear is fixedly connected to the circumferential surface of the rotating shaft. A rack ring is fixedly connected to the inner wall of the mixing tank.

[0008] Furthermore, the side of the gear meshes with the side of the rack ring, and the number of the mixing plates is set to several, in pairs, and arranged linearly on the circumference of the rotating rod. The gear design can achieve uniform rotation of the mixing plates, which can effectively ensure the uniform distribution of cement, sand and water in the mortar and avoid unstable mortar quality caused by uneven mixing.

[0009] Furthermore, the number of rack rings is set to two, and they are arranged in a linear array on the inner wall of the mixing tank. The number of rotating rods is set to several, and they are arranged in a linear array on the circumference of the rotating rods. The design of the rack rings allows the mixing plate to rotate on its own axis during the revolution, thereby improving the mixing effect.

[0010] Furthermore, a water injection device is provided at the top of the mixing tank. The water injection device includes a belt rotatably connected to the circumferential surface of a rotating rod. A rotating shaft is rotatably connected to the end of the belt away from the rotating rod. A helical gear is fixedly connected to the circumferential surface of the rotating shaft. A fixing plate is fixedly connected to the top of the mixing tank. A water tank is fixedly connected to the side of the fixing plate. A flexible hose passes through the side of the water tank. A connecting pipe passes through the end of the flexible hose away from the water tank. A round rod is rotatably connected to the side of the fixing plate. A fixing block is fixedly connected to the circumferential surface of the round rod. A bevel gear is fixedly connected to the circumferential surface of the round rod.

[0011] Furthermore, a storage tank is provided at the bottom of the mixing tank, and a scale is fixedly connected to the side of the storage tank. The scale on the side of the storage tank clearly indicates the amount of water loss, enabling operators to quickly and accurately read the rate of water loss.

[0012] Furthermore, the side of the bevel gear meshes with the side of the helical gear, and the end of the connecting pipe away from the hose passes through the top of the mixing tank. Through the linkage of mechanical components such as the helical gear and bevel gear, the pumping and loss of water is automatically simulated, reducing the tediousness of manual operation.

[0013] Furthermore, the hose is made of rubber and is located on the movement trajectory of the fixed block. The elasticity and squeezing action of the hose simulate the periodic changes of moisture loss, while the design of the scale and storage box can clearly and intuitively display the process of moisture loss.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes the force of a motor-driven rotating rod to interact with components such as the mixing plate, rack and pinion ring, and gears in the mixing device. This achieves the effect of uniformly mixing mortar by rotating the shaft, causing the gears to mesh with the rack and pinion ring and rotate, which in turn drives the shaft to rotate, which in turn drives the rotating rod to rotate, and finally the rotating rod drives the mixing plate to rotate. This process ensures the uniform distribution of cement, sand, and water in the mortar and avoids unstable mortar quality caused by uneven mixing.

[0016] This invention utilizes the force of a rotating rod driving a belt to rotate, which, in conjunction with components such as helical gears, bevel gears, and fixed blocks in the water injection device, pumps fluid by alternately squeezing and releasing the hose as the fixed block continuously presses it. As the fixed block rolls, the hose's elasticity causes it to continuously return to its original shape, creating a negative pressure at the water tank outlet. This allows water from the tank to enter the mixing tank through the hose and connecting pipe, achieving automatic water addition to the mortar surface. This not only improves work efficiency but also avoids human error, resulting in more accurate and consistent test results.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The side of gear 207 meshes with the side of rack ring 208. The number of mixing plates 205 is set to several, in pairs, and arranged in a linear array on the circumference of rotating rod 203.

[0030] The number of rack rings 208 is set to two and arranged linearly on the inner wall of the mixing tank 101. The number of rotating rods 204 is set to several and arranged linearly on the circumferential surface of the rotating rod 203. The design of the rack rings 208 allows the mixing plate 205 to rotate on its own axis during the revolution, thereby improving the mixing effect.

[0031] A water injection device 3 is provided on the top of the mixing tank 101. The water injection device 3 includes a belt 301, which is rotatably connected to the circumferential surface of the rotating rod 203. A rotating shaft 302 is rotatably connected to the end of the belt 301 away from the rotating rod 203. A helical gear 303 is fixedly connected to the circumferential surface of the rotating shaft 302. A fixing plate 304 is fixedly connected to the top of the mixing tank 101. A water tank 305 is fixedly connected to the side of the fixing plate 304. A flexible hose 306 passes through the side of the water tank 305.

A fixing block 309 is fixedly connected to the circumferential surface of the round rod 308. A bevel gear 310 is fixedly connected to the circumferential surface of the round rod 308.

[0032] A storage tank 103 is provided at the bottom of the mixing tank 101. A scale 104 is fixedly connected to the side of the storage tank 103. The scale 104 on the side of the storage tank 103 clearly indicates the amount of water loss, so that the operator can quickly and accurately read the rate of water loss.

[0033] The side of the bevel gear 310 meshes with the side of the helical gear 303. The end of the connecting pipe 307 away from the hose 306 passes through the top of the mixing tank 101. Through the linkage of mechanical components such as the helical gear 303 and the bevel gear 310, the pumping and loss simulation of water is automatically completed, reducing the tediousness of manual operation.

[0034] The hose 306 is made of rubber and is located on the movement trajectory of the fixed block 309.

[0035] A specific application of this embodiment is as follows: The motor 202 drives the rotating rod 203 to rotate, which in turn drives the rotating rod 204 to rotate. The rotating rod 204 then drives the mixing plate 205 to rotate, which in turn drives the rotating shaft 206 to rotate. The rotating shaft 206 then drives the gear 207 to rotate, causing the gear 207 to mesh with the rack ring 208 and rotate. The gear 207 then drives the rotating shaft 206 to rotate, which in turn drives the rotating rod 204 to rotate. The rotating rod 204 then drives the mixing plate 205 to rotate, achieving uniform mixing of the mortar and improving the mixing effect. The rotating rod 203 drives the belt 301 to rotate, which in turn drives the rotating shaft 302 to rotate. The rotating shaft 302 then drives the helical gear 303 to rotate, which in turn drives the conical... The gear 310 rotates, which in turn drives the round rod 308 to rotate. The round rod 308 then drives the fixed block 309 to rotate, squeezing the hose 306. This continuous squeezing of the hose 306 by the fixed block 309 pumps fluid by alternating squeezing and releasing. As the fixed block 309 rolls, the elasticity of the hose 306 causes it to continuously return to its original shape, creating a negative pressure at the outlet of the water tank 305. This allows water in the water tank 305 to enter the mixing tank 101 through the hose 306 and connecting pipe 307, thus automatically adding water to the mortar surface. The water in the mortar enters the storage tank 103 through the filter hole at the bottom of the mixing tank 101. The scale 104 on the side of the storage tank 103 provides clear readings, facilitating the observation and recording of the water loss rate.
