Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a drying box for concrete samples. Background Technique

[0002] The concrete drying box is mainly used for drying samples such as concrete test blocks and test rods to remove the moisture in the samples and ensure the accuracy of test data. It is widely used in various concrete performance tests such as concrete compressive strength test, flexural test, water absorption test, spalling test, and shrinkage test.

[0003] However, when the existing concrete sample drying boxes are put into use, the staff need to place the concrete samples on the top of the storage plate and then dry the concrete samples with hot air. However, most of the concrete sample drying boxes need to dry multiple concrete samples. Since the staff manually place the concrete on the top of the storage plate, it is easy to cause uneven distribution of multiple concrete samples, resulting in a decrease in the drying effect of the concrete samples.

[0004] At the same time, some concrete sample drying boxes heat the air inside the drying box from the bottom through a heating plate. However, since the air inside the drying box is gradually heated from low to high, the concrete samples at the bottom will be dried faster than the concrete samples in the upper part, resulting in uneven drying of the concrete samples inside the drying box.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1-6As shown in the figure, a drying box for concrete samples includes a working shell 1. The working shell 1 allows the concrete samples to be processed inside it. A switch door 2 is hinged on one side of the working shell 1. The switch door 2 enables the staff to put the concrete samples into the interior of the working shell 1. A support plate 3 is slidably connected to the inner cavity of the working shell 1. The support plate 3 can be used to place the concrete samples. A handle 4 is bolted to the side of the support plate 3 close to the switch door 2. The handle 4 is designed to be hollow. Under the action of the handle 4, the staff can pull out the support plate 3 from the interior of the working shell 1, thus facilitating the staff to place the concrete samples on the top of the support plate 3. A fixed shell 5 is bolted to the top of the support plate 3. A rotating mechanism 6 is arranged on one side of the fixed shell 5. A first gear rack 7 is slidably connected to the upper part of the inner cavity of the fixed shell 5, and a second gear rack 8 is slidably connected to the lower part of the inner cavity of the fixed shell 5. With the cooperation of the fixed shell 5 and the rotating mechanism 6, the first gear rack 7 and the second gear rack 8 can move in opposite directions simultaneously. A guide block 9 is bolted to the top of the first gear rack 7. The surface of the guide block 9 is slidably connected to the inner cavity of the fixed shell 5. Under the action of the guide block 9, the first gear rack 7 can move more stably, thereby increasing the stability of the drying box. A connecting rod 10 is bolted to one side of the first gear rack 7. The other end of the connecting rod 10 is bolted to a moving plate 11. The bottom of the moving plate 11 is slidably connected to the top of the support plate 3. With the cooperation of the first gear rack 7 and the second gear rack 8, the connecting rod 10 can drive the moving plates 11 on both sides to move in opposite directions simultaneously, enabling the moving plates 11 to clamp concrete samples of different sizes. And due to the number of the moving plates 11, the concrete samples can be evenly distributed on the top of the support plate 3, increasing the drying effect of the drying box on the concrete samples. A blower pump 12 is bolted to one side of the working shell 1. An installation shell 13 is bolted to the bottom of the inner cavity of the working shell 1. The air outlet of the blower pump 12 is communicated with one side of the installation shell 13. Under the action of the blower pump 12, air can enter the interior of the installation shell 13. A heating pipe 14 is arranged at the bottom of the inner cavity of the installation shell 13. Under the action of the heating pipe 14, the air inside the installation shell 13 can be heated. A conveying mechanism 15 is arranged on one side of the working shell 1. Under the action of the conveying mechanism 15, the air heated by the heating pipe 14 can dry the concrete samples placed on the moving plates 11, and the hot air can evenly dry multiple concrete samples, thereby increasing the practicability of the drying box.

[0025] The rotating mechanism 6 includes a hand-rotating rod 61 arranged on one side of the fixed housing 5. One side of the hand-rotating rod 61 is fixed with a rotating shaft 62. The surface of the rotating shaft 62 is rotatably connected to one side of the fixed housing 5. The other side of the rotating shaft 62 is fixed with a spur gear 63. The surface of the spur gear 63 is meshed with one side of the first rack 7 and the second rack 8 respectively. With the cooperation of the hand-rotating rod 61 and the rotating shaft 62, the spur gear 63 can be rotated. The spur gear 63 drives the connecting rod 10 through the first rack 7 and the second rack 8 to drive the moving plates 11 on both sides to move in opposite directions at the same time, so as to place concrete samples of different sizes. Moreover, different rotating shafts 62 are connected by a timing belt drive, so that multiple groups of moving plates 11 move synchronously.

[0026] The conveying mechanism 15 includes a connecting pipe 151. One end of the connecting pipe 151 is communicated with one side of the mounting housing 13. A fixed pipe 152 is fixed in the inner cavity of the working housing 1. One side of the fixed pipe 152 is communicated with the other end of the connecting pipe 151. The surface of the fixed pipe 152 is communicated with a spray head 153. The number of spray heads 153 is several and is designed at equal intervals on the surface of the fixed pipe 152. With the cooperation of the connecting pipe 151 and the fixed pipe 152, the heated air inside the mounting housing 13 can enter the inside of the spray head 153. As the spray head 153 can dry concrete samples at different levels, the hot air dries the concrete samples more comprehensively, thereby increasing the practicability of the drying oven. A fixed sleeve 16 is bolted on the surface of the working housing 1. The inner cavity of the fixed sleeve 16 is fixedly connected to the surface of the connecting pipe 151. Under the action of the fixed sleeve 16, the situation that the connecting pipe 151 is displaced during work can be effectively prevented, and the stability of the conveying mechanism 15 is increased, thereby increasing the stability of the drying oven.

[0027] Working principle: First, the operator opens the switch door 2. Then, under the action of the handle 4, the support plate 3 can be moved out of the interior of the working shell 1. With the cooperation of the hand-rotating rod 61 and the rotating shaft 62, the spur gear 63 can be rotated. The spur gear 63 drives the connecting rod 10 through the first toothed bar 7 and the second toothed bar 8 to drive the moving plates 11 on both sides to move in opposite directions simultaneously, enabling the operator to place the concrete samples in the inner cavity of the moving plates 11. Moreover, the rotating shaft 62 can drive the moving plates 11 on one layer to move simultaneously through two belt pulleys and a timing belt, allowing the operator to place multiple concrete samples on the top of the support plate 3. Subsequently, the operator drives the support plate 3 with the concrete samples into the interior of the working shell 1 through the handle 4. The operator closes the switch door 2. Under the action of the blower pump 12, air can enter the interior of the installation shell 13, and with the cooperation of the heating tube 14, the air can be heated. With the continuous operation of the blower pump 12, the heated air can enter the interior of the fixed tube 152 through the connecting tube 151. Then, with the cooperation of multiple nozzles 153, the hot air can be used to dry the concrete samples. After drying, the operator can take out the processed concrete samples.
