Moreover, the horizontality of the base is adjusted through the second support rod, so that the curing box is kept horizontally placed, which is beneficial to the condensation of cement inside the curing box, the heat separation screen plate disperses the air heated by the heating plate, and the heat transfer column transfers the heat to the heating plate, so as to keep the heat inside the box shell quickly and evenly transferred.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] In the prior art, in order to drive the cement test bench to move up and down in the cement constant temperature curing box, it usually relies on the forward and reverse rotation of the drive motor. However, this design has significant shortcomings. In the actual operation process, the drive motor will generate a large impact when switching between forward and reverse rotations, which may not only cause increased wear of mechanical parts, but also cause vibration and noise, which will have an adverse effect on the cement specimens in the curing box, such as affecting its coagulation process. In addition, frequent impacts may also cause the service life of the drive motor to be significantly reduced, increasing the cost of maintenance and replacement. Therefore, the design of the drive motor in the prior art needs to be further improved to reduce impact, improve stability and service life, so as to ensure that the cement specimens are better maintained in the curing box.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A cement constant temperature water curing box, comprising a box body 1, characterized in that: the box body 1 is set to be cylindrical, a box door 2 is rotatably provided on the box body 1, a conical base 3 is fixedly provided inside the box body 1, a support plate 4 is fixedly provided on the base 3, a rotating rod 5 is rotatably provided on the support plate 4, a screw 6 is fixedly sleeved on the rotating rod 5, a plurality of guide tubes 7 are fixedly provided on the base 3, a plurality of guide tubes 8 are slidably provided in the plurality of guide tubes 7, a material receiving plate 9 is fixedly provided on the guide rod 8, a screw sleeve 10 is fixedly provided on the material receiving plate 9, the screw sleeve 10 cooperates with the screw 6, when the screw 6 rotates, the material receiving plate 9 slides up and down through the guide tube 7 and the guide rod 8, a reciprocating driving mechanism 11 for driving the rotating rod 5 to reciprocate is provided on the support plate 4, and a cleaning mechanism 18 for cleaning the side wall of the box body 1 is provided in the box body 1;

[0029] The box body 1 in this embodiment adopts a cylindrical design. This shape is conducive to achieving uniform distribution of space in the box body 1, ensuring that the cement specimens are more evenly affected by temperature during the curing process. The box door 2 is arranged on the box body 1 and can be easily opened and closed, which is convenient for putting in and taking out the cement specimens. The base 3 adopts a conical design to facilitate water flow convergence. A support plate 4 is fixedly arranged on the base 3 for supporting a rotating rod 5 and other related components. The rotating rod 5 is rotatably arranged on the support plate 4, and a screw 6 is fixedly sleeved thereon. The rotation of the screw 6 will drive the material receiving plate 9 to move. Since the material receiving plate 9 is constrained by the conduit 7, the material receiving plate 9 can only move in a straight line along the axial direction of the screw 6.

[0030] Embodiment 2:

[0031] Based on the first embodiment, this embodiment describes the reciprocating drive mechanism 11 of the first embodiment.

[0032] The reciprocating drive mechanism 11 includes a driving gear 12 rotatably arranged on the support plate 4, a driven gear 13 is fixedly arranged on the rotating rod 5, a rack 14 is slidably arranged on the support plate 4, the rack 14 is meshed with the driven gear 13, a connecting rod 15 is rotatably arranged between the driving gear 12 and the rack 14, when the driving gear 12 rotates, the rack 14 is driven to reciprocate linearly on the support plate 4 through the connecting rod 15, a driving motor 16 is fixedly arranged on the support plate 4, a worm 17 is fixedly sleeved on the shaft of the driving motor 16, and the worm 17 is meshed with the driving gear 12 for transmission;

[0033] In this embodiment, the driving gear 12 is rotatably arranged on the support plate 4, and is the core component that drives the entire mechanism to reciprocate. When the driving motor 16 rotates, the driving motor 16 drives the worm 17 to rotate, and the worm 17 rotates to drive the driving gear 12 to rotate. When the driving gear 12 rotates, the rack 14 is driven by the connecting rod 15 to realize reciprocating linear motion. It should be noted that the connecting rod 15 is rotatably connected to the eccentric position of the driving gear 12. At this time, when the driving gear 12 rotates, it is equivalent to a crank. Therefore, the driving gear 12, the connecting rod 15 and the rack 14 together constitute a crank slider mechanism. The crank slider mechanism can convert rotational motion into reciprocating linear motion. The driving motor 16 in this embodiment is a technology well known to technicians in the technical field, and is a commonly used device in the technical field. The operator can select a suitable driving motor 16 according to the actual space size, speed, power and other parameters, which will not be repeated here.

[0034] By driving the motor 16 and other components, the rack 14 is driven to move back and forth linearly. When the rack 14 moves back and forth linearly, the driven gear 13 meshing with it can also realize reciprocating rotation. When the driven gear 13 rotates back and forth, the rotating rod 5 and the screw 6 also rotate at the same speed. When the screw 6 rotates, the screw sleeve 10 and the receiving plate 9 are driven to realize linear motion along the axial direction of the screw 6 (the screw sleeve 10 of the screw 6 can convert rotational motion into linear motion). The receiving plate 9 is constrained by the guide tube 7. Therefore, the receiving plate 9 can only move linearly along the axial direction of the screw 6. When the screw 6 rotates back and forth, the receiving plate 9 can also move up and down reciprocatingly, so as to realize uniform temperature of the cement sample in the curing box. At the same time, the driving motor 16 only needs to rotate in one direction, which avoids the impact phenomenon of the driving motor 16 when changing direction, and increases the service life of the driving motor 16.

[0035] Embodiment three:

[0036] On the basis of the first embodiment, considering that during the curing process of cement, water stains and other impurities will be attached to the side walls of the curing box, if they are not removed in time, it will affect the normal operation of the box body 1 and the curing effect. Therefore, in this embodiment, a cleaning mechanism 18 is provided to clean the side walls of the box body 1;

[0037] The cleaning mechanism 18 includes a gear ring 19 rotatably disposed in the box body 1, the gear ring 19 is meshed with the driving gear 12, a plurality of scrapers 20 are fixedly disposed on the gear ring 19, and the scrapers 20 are arranged in a spiral shape. The inner wall of the box body 1 is provided with a heat preservation layer 21, and the bottom of the box body 1 is provided with a drain port 22 for draining the accumulated water in the box body 1. A control panel 23 is provided on the outside of the box body 1, and an observation window 24 is fixedly provided on the box door 2;

[0038] In this embodiment, the gear ring 19 is rotatably arranged in the housing 1 and meshes with the driving gear 12 in the aforementioned reciprocating drive mechanism 11. When the driving gear 12 rotates, the gear ring 19 rotates accordingly, thereby driving the entire cleaning mechanism 18 to work. The scrapers 20 are fixedly arranged on the gear ring 19, and the number thereof is determined according to the area of ​​the inner wall of the housing 1 and the degree of the stains to be cleaned. The scrapers 20 are arranged in a spiral shape. The purpose of such a design is to ensure that when the gear ring 19 rotates, the scrapers 20 can fully and effectively clean the stains and water stains on the inner wall of the housing 1.

[0039] In addition to the cleaning mechanism 18, the cement constant temperature water curing box in the embodiment of the present invention also pays special attention to the insulation and drainage functions. The inner wall of the box body 1 is provided with an insulation layer 21, which is to ensure the temperature inside the box body 1 is stable and reduce the influence of the external temperature on the curing of the cement specimen. The insulation layer 21 is made of high-efficiency insulation material and has a good insulation effect. The insulation layer 21 is a technology well known to technicians in the technical field and is a commonly used device in the technical field, so it will not be described here;

[0040] The bottom of the box body 1 is provided with a drain port 22 for draining the accumulated water in the box body 1. The purpose of such design is to prevent the accumulated water from causing adverse effects on the cement specimens and ensure the dryness and hygiene of the curing environment.

[0041] Working principle: During the use of the utility model, when the cement constant temperature water curing box is needed, the user first opens the box door 2, places the cement test piece on the material receiving plate 9, and then closes the box door 2, sets the temperature in the box body 1 through the control panel 23, and after the driving motor 16 is started, it will drive the worm 17 to rotate, and the worm 17 will mesh with the driving gear 12 to drive the driving gear 12 to rotate. When the driving gear 12 rotates, it will drive the rack 14 to reciprocate on the support plate 4 through the connecting rod 15, thereby driving the rotating rod 5 to reciprocate. The screw 6 on the rotating rod 5 will drive the material receiving plate 9 to slide up and down, thereby adjusting the height of the cement specimen so that it can be fully maintained. At the same time, the rotation of the active gear 12 will also drive the gear ring 19 and the scraper 20 to rotate together to clean the stains and residues on the side wall of the box 1. Under the action of the thermal insulation layer 21, the temperature in the box 1 will remain stable. The user can observe the condition of the cement specimen in the box 1 through the observation window 24 and adjust the temperature in the box 1 as needed. When the cement specimen needs to be taken out, the user opens the box door 2 and takes out the specimen.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
