Description

Technical Field

[0001] This application relates to the field of engineering material testing technology, and in particular to a stirring device for ash dosage testing. Background Technology

[0002] Lime, cement, and soil are frequently used as fill materials in highway engineering roadbed construction. When inorganic binders such as lime and cement are uniformly mixed with soil, a series of physical and chemical reactions occur over time. These continuous reactions improve the physical properties of the natural soil, and after compaction, the lime-cement-soil structure develops both early and later strength, with particularly high structural stiffness in the later stages. The selection of the lime dosage in the mixture of inorganic binders and soil is crucial. Lime dosage tests can help determine the optimal lime dosage for a specific mixture.

[0003] Using a mixer instead of manual mixing during ash dosage testing allows for stable mixing of the ash at a consistent speed, reducing the workload for workers. Before each ash dosage test, the ash container needs to be kept clean. However, the mixing components of the mixer need to extend into the ash container below, making the discharge and cleaning process inconvenient. If the ash container is removed to simplify the discharge and cleaning process, either the container or the mixer needs to be designed with a liftable installation method, making the equipment structure more complex. Utility Model Content

[0004] To make the ash container for ash dosage testing easier to discharge and clean, this application provides an ash dosage testing stirring device.

[0005] The ash dosage test stirring device provided in this application adopts the following technical solution:

[0006] A stirring device for ash dosage testing includes a frame, a stirring rod, and a drive mechanism. The stirring rod is rotatably mounted on the frame, and the drive mechanism drives the stirring rod to rotate. The stirring rod has a hinge structure close to the drive mechanism. The stirring rod is detachably provided with a limiting pin, which is simultaneously connected to two movable ends of the hinge structure. The limiting pin is offset from the hinge center of the hinge structure.

[0007] By adopting the above technical solution, when it is necessary to move the ash container, the limiting pin is separated from one of the movable ends of the hinge structure. The main body of the stirring rod can rotate around the hinge center of the hinge structure, allowing the stirring rod to be lifted upwards. This facilitates moving the ash container into or out of the area below the stirring rod, enabling direct replacement of the ash container or removal for cleaning, making the discharge and cleaning of the ash container more convenient. When the limiting pin is simultaneously engaged with both movable ends of the hinge structure, the hinge movement of the stirring rod is limited, keeping the stirring rod in a fixed position to perform its stirring function.

[0008] Optionally, the drive mechanism includes a motor, a drive gear, and a driven gear. The motor is detachably mounted on the frame, the drive gear is mounted on the output shaft of the motor, and the driven gear is mounted on the stirring rod.

[0009] By adopting the above technical solution, the motor can indirectly drive the stirring rod to rotate through the driving gear and the driven gear, so that the stirring rod can stir the ash at a stable speed. The motor is detachably mounted on the frame, and the specifications of the motor and the driving gear can be changed as needed to give the stirring paddle different speed levels and thus change the experimental results.

[0010] Optionally, the ash dosage test stirring device also includes a timer switch, which is electrically connected to the motor.

[0011] By adopting the above technical solution and controlling the motor operation through a timer switch, the stirring time can be precisely controlled.

[0012] Optionally, the motor is connected to the frame via a bolt and nut assembly. The frame is provided with a plurality of bolt holes for mounting the bolt and nut assembly. The bolt holes are oblong holes, and the length direction of the oblong holes is along the center line connecting the driving gear and the driven gear.

[0013] By adopting the above technical solution, when replacing the drive gear with different sizes and specifications, the installation position of the motor can be adjusted to adapt to the change in the center distance between the drive gear and the driven gear.

[0014] Optionally, one end of the limiting pin is provided with a limiting flange, and the limiting pin gradually extends downward in a direction away from the limiting flange.

[0015] By adopting the above technical solution, the stirring rod will vibrate during the stirring process. When the stirring rod vibrates, the limiting pin will move axially. By setting a limiting flange at the higher end of the limiting pin, the situation where the limiting pin comes out of the stirring rod along its own axial direction can be reduced.

[0016] Optionally, two limiting pins are provided, and the two limiting pins are respectively located on the upper and lower sides of the hinge center line of the hinge structure, and are triangularly distributed with the center line of the hinge structure.

[0017] By adopting the above technical solution, the hinge point of the hinge structure and the two limiting pins are triangularly distributed, making the stirring rod more stable and reliable in use.

[0018] Optionally, the frame is provided with a support structure, which includes a movable block and a return spring. The movable block is used to support the stirring rod. The movable block is slidably connected to the frame in a horizontal direction. The sliding direction of the movable block in the frame is perpendicular to the axis of the stirring rod. The movable block is provided with a guide slope. The movable block is located within the rotation path range of the stirring rod. The stirring rod can push the movable block through the guide slope. The return spring is used to force the movable block to remain within the rotation path range of the stirring rod.

[0019] By adopting the above technical solution, during the upward rotation of the stirring rod, a horizontal thrust is applied to the movable block via the guide ramp. This causes the movable block to overcome the elastic force of the return spring and move to avoid the stirring rod, allowing the stirring rod to rotate above the movable block. After the stirring rod passes the movable block, the movable block moves back to its original position under the elastic force of the return spring, thus supporting the stirring rod. The stirring rod is supported by a support structure, making it easy for workers to move the ash container into or out of the area below the stirring rod.

[0020] Optionally, the stirring rod includes a rod body and blades, the blades include a base plate and two adjusting plates, the base plate is connected to the rod body, and the two adjusting plates are detachably connected to both ends of the base plate.

[0021] By adopting the above technical solution, the blade adjustment plate and the base plate are detachably connected, and the size and specifications of the blade can be changed by replacing the adjustment plate with different sizes and specifications.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When it is necessary to move the ash container, the limiting pin is separated from one of the movable ends of the hinge structure, and the main body of the stirring rod can rotate around the hinge center of the hinge structure, so that the stirring rod can be lifted up, so as to move the ash container into or out of the area below the stirring rod, so as to directly replace the ash container or remove the ash container for cleaning, making the discharge and cleaning of the ash container more convenient.

[0024] 2. The stirring rod is supported by a support structure, making it easy for workers to move the ash container into or out of the area under the stirring rod. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] Example 1

[0033] This application discloses a stirring device for ash dosage testing. (Refer to...) Figure 1 The ash dosage test stirring device includes a frame 1, a stirring rod 2, a drive mechanism 3, and a timer switch 4. The stirring rod 2 is rotatably mounted on the frame 1. The drive mechanism 3 includes a motor 31, a drive gear 32, and a driven gear 33. The motor 31 is detachably connected to the frame 1. The drive gear 32 is detachably mounted on the output shaft of the motor 31, and the driven gear 33 is detachably mounted on the stirring rod 2. The timer switch 4 is located on the power supply line of the motor 31.

[0034] The driving gear 32 and the driven gear 33 can be installed by combining a key-bar fit with an interference fit, or by combining a key-bar fit with a set screw connection.

[0035] During the use of the ash dosage test stirring device, the motor 31 indirectly drives the stirring rod 2 to rotate and stir the ash in the ash container 8 through the driving gear 32 and the driven gear 33. The stirring time of the motor 31 can be precisely controlled by the timer switch 4. The motor 31 can be disassembled and replaced with different specifications to obtain different stirring speed levels.

[0036] The motor 31 is connected to the frame 1 by four bolt and nut assemblies 5. The frame 1 has four bolt holes 11, which correspond to four bolt and nut assemblies 5 respectively. The bolts of the bolt and nut assemblies 5 pass through the corresponding bolt holes 11. The bolt holes 11 are oblong holes, and the length direction of the oblong holes is along the center line connecting the driving gear 32 and the driven gear 33.

[0037] The specifications of the drive gear 32 on the motor 31 can be changed as needed. When replacing the drive gear 32 with different sizes, the installation position of the motor 31 can be adjusted to accommodate changes in the center distance between the drive gear 32 and the driven gear 33. The drive gear 32 can be replaced as a whole with the motor 31, or it can be disassembled and replaced separately. Correspondingly, the driven gear 33 on the stirring rod 2 can also be disassembled and replaced separately.

[0038] The frame 1 is provided with a limit adjustment structure 6, which is located on the side of the motor 31 away from the stirring rod 2. The limit adjustment structure 6 includes a fixed seat 61 and an adjusting bolt 62. The fixed seat 61 is fixedly installed on the frame 1, and the adjusting bolt 62 is threadedly connected to the fixed seat 61. One end of the adjusting bolt 62 abuts against the side of the motor 31 away from the stirring rod 2.

[0039] When installing the motor 31, before locking the motor 31 with the bolt and nut assembly 5, first use the adjusting bolt 62 to push the motor 31 closer to the stirring rod 2, so that the driving gear 32 and the driven gear 33 are tightly meshed.

[0040] The stirring rod 2 is provided with a hinge structure 23, which is close to the driven gear 33. The stirring rod 2 is detachably provided with a limit pin 24. One end of the limit pin 24 is provided with a limit flange 241. The limit pin 24 is connected to both movable ends of the hinge structure 23. The movable ends of the hinge structure 23 refer to the two hinge connection parts of the hinge structure 23. The limit pin 24 is offset from the hinge center of the hinge structure 23.

[0041] The stirring rod 2 includes a rod body 21 and a blade 22. The blade 22 includes a base plate 221 and two adjusting plates 222. The base plate 221 is connected to the rod body 21, and the two adjusting plates 222 are detachably connected to the two ends of the base plate 221 via bolt and nut assemblies 5. The combination structure of the base plate 221 and the adjusting plates 222 forms the blade 22. By replacing the adjusting plates 222 with different specifications, the size of the blade 22 can be changed.

[0042] Reference Figure 1 and Figure 2The frame 1 is provided with a support structure 7, which includes a movable block 71 and a return spring 72. The movable block 71 is used to support the stirring rod 2. The frame 1 is provided with a horizontal slide rail 12. The movable block 71 is provided with a groove 712 adapted to the horizontal slide rail 12. The movable block 71 and the horizontal slide rail of the frame 1 are slidably connected in the horizontal direction. The sliding direction of the movable block 71 is perpendicular to the axis of the stirring rod 2. The movable block 71 is provided with a guide slope 711. The guide slope 711 is inclined downward. The movable block 71 is located within the rotation path range of the stirring rod 2. The stirring rod 2 can push the movable block 71 through the guide slope 711. The return spring 72 is used to force the movable block 71 to remain within the rotation path range of the stirring rod 2.

[0043] During the upward rotation of the stirring rod, a horizontal thrust is applied to the movable block 71 via the guide ramp 711. This causes the movable block 71 to overcome the elastic force of the return spring 72 and move to avoid the stirring rod 2, allowing the stirring rod 2 to rotate above the movable block 71. After passing the movable block 71, the movable block 71 moves back to its original position under the elastic force of the return spring 72, thus supporting the stirring rod 2. The stirring rod 2 is supported by the support structure 7, facilitating the movement of the ash container 8 into or out of the area below the stirring rod 2. During the upward rotation of the stirring rod 2, the ash container 8 can move horizontally along with the rotation direction of the stirring rod 2, thus resolving the interference problem between the stirring rod 2 and the side wall of the container.

[0044] The implementation principle of the ash dosage test stirring device in this application embodiment is as follows: (Refer to...) Figure 1 and Figure 2 When the ash container 8 needs to be moved, the limiting pin 24 is separated from one of the movable ends of the hinge structure 23, allowing the main body of the stirring rod 2 to rotate around the hinge center of the hinge structure 23. This allows the stirring rod 2 to be lifted upwards, facilitating the movement of the ash container 8 into or out of the area below the stirring rod 2. This facilitates direct replacement of the ash container 8 or removal for cleaning, making the discharge and cleaning of the ash container 8 more convenient. When the limiting pin 24 is simultaneously engaged with both movable ends of the hinge structure 23, the hinge movement of the stirring rod 2 is limited, keeping the stirring rod 2 in a fixed position to perform its stirring function.

[0045] Example 2

[0046] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that there are two limiting pins 24 in this embodiment. The two limiting pins 24 are located on the upper and lower sides of the hinge center line of the hinge structure 23, and are triangularly distributed with the center line of the hinge structure 23, so that the structure of the stirring rod 2 is more stable.

[0047] In addition, in this embodiment, the limiting pin 24 extends downwards at a gradually downward angle away from the limiting flange 241. During the stirring process, the stirring rod 2 vibrates, causing the limiting pin 24 to move axially. By providing the limiting flange 241 at the higher end of the limiting pin 24, the possibility of the limiting pin 24 disengaging from the stirring rod 2 along its own axial direction can be reduced.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
