Description

Technical Field

[0001] This utility model relates to the field of cement testing technology, and in particular to a sample retention device for measuring the strength of silicate cement. Background Technology

[0002] With economic development, the construction industry has developed rapidly. Cement is a very important material in the construction field, and it affects the overall safety of buildings.

[0003] Silicate cement, as one of the most widely used basic building materials in the world, is the core cementitious material of concrete structures. Its strength properties directly determine the compressive strength, flexural strength, durability and seismic resistance of buildings.

[0004] Currently, cement sampling methods are relatively simple. Traditional sampling methods use paper bags or plastic buckets for sealing, which cannot guarantee the accuracy of the sample. Furthermore, the manual operation is cumbersome and the sample preparation efficiency is low, which cannot meet higher testing requirements. Therefore, there is a need for improvement. Utility Model Content

[0005] This utility model provides a silicate cement strength testing and retention device that can efficiently produce cement sample specimens, reduce manual operation, and has high specimen production efficiency and accuracy, thus meeting higher testing requirements. It solves the technical problems of existing technologies, such as the current simple retention method, which cannot guarantee the accuracy of specimen retention, and the cumbersome, time-consuming, and labor-intensive manual operation steps, resulting in low specimen production efficiency and inability to meet higher testing requirements.

[0006] The above-mentioned technical problem of this utility model is solved by the following technical solution: a silicate cement strength testing and sample retention device, including a conveying platform, a compaction platform connected to the right side of the conveying platform, a stirring device mounted above the conveying platform, a mold placed on the conveying platform below the stirring device, the mold having several forming cavities, and a compaction device mounted on the compaction platform. The stirring device above the conveying platform is used to stir and mix the silicate cement. The mixed cement is poured into the forming cavities of the mold below. The number of forming cavities of the mold can be adjusted according to needs, allowing multiple samples to be made simultaneously. The mold containing cement is further compacted by the compaction device to ensure the accuracy of the sample data. The compacted mold is then sent to a designated drying equipment for drying.

[0007] Preferably, the mixing device includes a mixing tank mounted above a conveying platform, with mixing blades inside the mixing tank, the mixing blades being driven by a motor. During manufacturing, a specified proportion of material is first poured into the mixing tank, and after being mixed by the mixing blades, the material is discharged.

[0008] Preferably, the mixing device also includes several discharge pipes installed at the bottom of the mixing tank, which are controlled by valves. During manufacturing, cement is first poured into the mixing tank, and after mixing, it is discharged from the discharge pipes. The discharge pipes discharge equal amounts of cement through valves and program control, and the material falls into the forming cavity of the mold below.

[0009] Preferably, the conveying platform is equipped with a conveyor belt, on which the mold is placed and transported. The conveyor belt of the conveying platform can drive the mold to be transported, and the conveyor belt can be stopped when the mold reaches the desired position via a sensor. The conveyor belt stops when the mold is transported to the bottom of the mixing tank.

[0010] Preferably, the mold is equipped with a flip-open cover. The cover is open when cement is poured in, and needs to be closed and locked during vibration.

[0011] Preferably, the compaction device includes a base slidably mounted on a compaction platform. The base has a concave structure, and the compaction platform has guide grooves on its front and rear sides. The mold is embedded in the groove of the base, and the base slides up and down along the grooves.

[0012] Preferably, the base has latches on both the front and rear sides, and the mold has corresponding hooks on both the front and rear sides. The mold containing cement is placed on the base, the cover plate is locked, and the mold is secured to the base using the latches.

[0013] Preferably, the compaction device further includes a rotating shaft rotatably mounted below the compaction platform, with several cams spaced apart on the shaft, the cams resting against the bottom surface of the base. The rotating shaft drives the cams to rotate, causing the mold to vibrate up and down under the action of the cams, thus compacting the cement inside. The rotation time of the pulley can be controlled by a program, stopping after a specified time. The compacted mold can then be removed and placed in a designated drying equipment for further processing.

[0014] Preferably, the rotating shaft is driven by a pulley or a motor. The rotating shaft can be driven directly by a motor or by a pulley; this invention will be described using a pulley drive as an example.

[0015] Therefore, the silicate cement strength testing and sample retention device of this utility model has the following advantages: it can efficiently produce cement sample specimens, reduce manual operation, and has high specimen production efficiency and accuracy, which can meet higher testing requirements.

[0024] like Figure 1 and 2 As shown in Figures 3, 4, and 5, a sample retention device for determining the strength of silicate cement includes a conveying platform 1 on the left, a circulating conveyor belt installed on the surface of the conveying platform 1, a mold 2 placed on the conveyor belt, a flip-open cover plate installed on the mold 2, and the conveyor belt drives the mold 2 to be conveyed to the right.

[0025] A stirring device is installed above the conveying platform 1. The stirring device includes a stirring tank 3 installed above the conveying platform 1. Stirring blades are installed inside the stirring tank 3 and are driven by a motor.

[0026] Three discharge pipes 4 are installed at intervals at the bottom of the mixing tank 3, and the discharge of materials is controlled by valves.

[0027] A compaction platform 5 is connected to the right side of the conveyor platform 1, and a compaction device is installed on the compaction platform 5.

[0028] The compaction device includes sliding grooves on the front and rear sides of the compaction platform 5. A base 6 is slidably installed in the sliding groove. The base 6 has a concave structure. Locks are installed on the front and rear sides of the base 6. Corresponding hook structures are installed on the front and rear sides of the mold 2.

[0029] The compaction device also includes a rotating shaft 7 rotatably mounted below the compaction platform 5. Three cams 8 are installed at intervals on the rotating shaft 7. Corresponding grooves are opened on the compaction platform 5, and the cams 8 abut against the bottom surface of the base 6 through the grooves.

[0030] The rotating shaft 7 is driven by a belt pulley.

[0031] The conveyor belt of the conveyor platform 1 can drive the mold 2 to be conveyed. The sensor can control the stop of the conveyor belt after the mold 2 is in place. The conveyor belt stops when the mold 2 is conveyed to the bottom of the mixing tank 3.

[0032] During production, cement is first poured into the mixing tank 3. After mixing, the cement is discharged through the discharge pipe 4. The discharge pipe 4 discharges the same amount of cement through the valve and the program control. The material falls into the forming cavity of the mold 2 below.

[0033] After the material is discharged, the conveyor belt continues to transport the cement-filled mold 2 on the base 6 via a signal from the valve. The cover plate is locked and the mold 2 is fixed to the base 6 with a buckle. Then, the motor of the pulley is turned on, and the pulley drives the rotating shaft 7 and cam 8 to rotate. Under the action of cam 8, the mold 2 vibrates up and down, and the cement inside is compacted. The rotation time of the pulley can be controlled by the program. It stops after the specified time is reached. The compacted mold 2 can be removed and placed in the designated drying equipment for further processing.

[0034] This invention allows for continuous cement sample processing, effectively increasing sample production efficiency, reducing manual operation, facilitating control, and making sample preparation more accurate.
