Description

Technical Field

[0001] This utility model relates to the technical field of concrete quality testing equipment, specifically a concrete quality testing device. Background Technology

[0002] Concrete is one of the most commonly used main materials in modern construction projects. Because construction parties or contractors have certain rigid standards for the acceptance or construction of buildings, it is necessary to conduct performance tests on the poured concrete, among which testing the concrete setting time is particularly common.

[0003] However, a utility model patent with authorization announcement number CN220568604U discloses a concrete quality testing device, including a base, a testing mechanism, an adjustment mechanism, and a limiting mechanism. The base has a supporting component on top to support the concrete to be tested. The testing mechanism includes a test needle corresponding to the supporting component, used to detect the setting time of the concrete within the supporting component during operation. The adjustment mechanism is installed inside the base and drives the supporting component to move up and down during operation. The limiting mechanism limits the height of the supporting component and includes a connecting frame installed on the side wall of the base, a limiting rod hinged to the side wall of the connecting frame, and a limiting seat with multiple limiting grooves evenly distributed along its circumference. This type of concrete quality testing device replaces traditional concrete quality testing devices, avoiding the problem of the test needle not adhering to the concrete surface, thus affecting the accuracy of the test.

[0004] The existing technical solutions described above have the following drawbacks: adjusting the height of the concrete bucket using components such as lead screws, moving sleeves, hinged rods, cranks, connecting frames, limiting rods, limiting seats, and limiting grooves results in a complex structure. Furthermore, the concrete falls directly into the inside of the bucket, leading to a loose and uneven surface. Additionally, workers need to manually lift and pour the concrete into the bucket, which is time-consuming and labor-intensive. Therefore, we propose a concrete quality testing device to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete quality testing device to solve the problems mentioned in the background art, such as the inconvenience of adjusting the height, the complicated adjustment structure, the difficulty in making the concrete in the storage bucket more compact and flat, and the difficulty in feeding the material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete quality testing device, comprising: a workbench, a mounting frame fixedly connected to the rear end of the workbench to bear load, and symmetrical connection holes on the front and rear of the workbench;

[0007] Also includes:

[0008] The upper front end of the mounting frame is bolted to a first cylinder, and a mounting frame is installed at the lower end of the first cylinder. A test needle is installed at the bottom end of the mounting frame. A swaying structure and a feeding structure are respectively provided on the lower and right sides of the mounting frame. The swaying structure includes a first connecting shaft, a first motor, an adjusting component, an adjusting frame, a connecting rod, a connecting ear, and a bearing plate. The feeding structure includes a feeding cylinder, a feeding port, a second connecting shaft, a second motor, blades, and a discharge pipe.

[0009] The connecting hole is internally nested with a guide rod, which is symmetrically fixed to the upper end of the base plate. The upper end of the base plate is bolted to a second cylinder, and the upper end of the second cylinder is installed at the middle position of the bottom end of the worktable.

[0010] Preferably, the first connecting shaft is rotatably connected to the middle position of the upper end of the worktable, and a first motor is installed at the bottom end of the first connecting shaft, and an adjusting component is fixedly connected at an equal angle to the outer surface of the upper end of the first connecting shaft.

[0011] Preferably, the adjusting component is disposed inside the adjusting frame, and both the left and right ends of the adjusting frame are integrally connected with connecting rods, and the connecting rods are connected through the inside of the connecting ears, and the lower end of the connecting ears is fixedly connected to the top of the worktable.

[0012] Preferably, a support plate is embedded in the upper end of the adjustment frame, and a storage bucket is bolted to the upper end of the support plate, wherein the support plate has a sliding structure on the upper side of the workbench through the adjustment component and the adjustment frame.

[0013] Preferably, the storage hopper has a lifting structure on the upper side of the base plate via a guide rod and a connecting hole.

[0014] Preferably, a feeding cylinder is fixedly connected to the lower right end of the workbench, and a feeding port is embedded in the lower right end of the feeding cylinder. A discharge pipe is welded to the upper left end of the feeding port, and the discharge pipe is set at an inclination.

[0015] Preferably, a second connecting shaft is rotatably connected inside the feeding cylinder, and a second motor is installed at the upper end of the second connecting shaft;

[0016] The outer surface of the second connecting shaft is inlaid with blades in a spiral structure, and the conveying cylinder is connected to the storage tank through the blades and the discharge pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the concrete quality testing equipment is easy to adjust in height, the adjustment structure is simple and stable, and it is also convenient to make the concrete in the storage bucket more compact and flat, while making it easy to feed materials;

[0018] 1. Equipped with a second cylinder and guide rods, the storage hopper is designed with guide rods and connecting holes on the upper side of the base plate. When the second cylinder is working, it drives the worktable to rise, allowing the worktable to slide upward on the symmetrically arranged guide rods, thus facilitating height adjustment. The adjustment structure is simple and stable.

[0019] 2. It is equipped with adjusting components and adjusting frames. The structural design of the adjusting components and adjusting frames on the upper side of the worktable allows the first connecting shaft to rotate, thereby driving the adjusting components that are set at equal angles to rotate.

[0020] When the adjusting component rotates, it contacts the inner wall of the adjusting frame, and the symmetrically arranged connecting rods slide left and right on the corresponding connecting ears, causing the storage bucket to sway left and right, thus making the concrete in the storage bucket more compact and flat.

[0021] 3. It is equipped with a conveying cylinder and blades. The conveying cylinder is connected to the storage tank through the blades and the discharge pipe, so that the blades rotate when the second connecting shaft rotates.

[0022] The spiral blades rotate to transfer the concrete at the bottom to the inside of the discharge pipe, and then the concrete is poured into the storage tank through the discharge pipe, making it easy to feed the concrete. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a concrete quality testing device, including a workbench 1, a mounting frame 2, a first cylinder 3, a mounting frame 4, a test needle 5, a first connecting shaft 6, a first motor 7, an adjusting component 8, an adjusting frame 9, a connecting rod 10, a connecting ear 11, a bearing plate 12, a storage bucket 13, a conveying cylinder 14, a feed inlet 15, a second connecting shaft 16, a second motor 17, a blade 18, a discharge pipe 19, a second cylinder 20, a base plate 21, a guide rod 22, and a connecting hole 23.

[0032] Example 1: Existing methods require workers to manually lift and pour concrete into concrete buckets, which is time-consuming and labor-intensive. Therefore, this example uses the following technical solution: Figure 1 and Figure 3 Since the feeding structure includes a feeding cylinder 14, a feeding port 15, a second connecting shaft 16, a second motor 17, blades 18, and a discharge pipe 19, the discharge pipe 19 is set at an inclination. The outer surface of the second connecting shaft 16 is inlaid with blades 18 in a spiral structure. The feeding cylinder 14 is connected to the storage tank 13 through the blades 18 and the discharge pipe 19. Therefore, the adjusting component 8 and the adjusting frame 9 drive the storage tank 13 to move to the right, so that the right end of the adjusting frame 9 is close to the connecting ear 11 on the right side. Concrete is poured into the inside of the feeding port 15. When the second motor 17 works, it drives the second connecting shaft 16 to rotate. When the second connecting shaft 16 rotates, it drives the blades 18 in a spiral distribution to rotate, transferring the concrete at the lower end of the feeding cylinder 14 to the inside of the discharge pipe 19. The concrete in the discharge pipe 19 is poured into the inside of the storage tank 13 along the inclined discharge pipe 19, thus making it easy to feed.

[0033] Example 2: Existing concrete is poured directly into the inside of the concrete bucket, resulting in loose and uneven concrete inside. Therefore, this example uses the following technical solution, such as... Figure 1 , Figure 2 and Figure 5The shaking structure includes a first connecting shaft 6, a first motor 7, an adjusting component 8, an adjusting frame 9, a connecting rod 10, a connecting ear 11, and a bearing plate 12. The adjusting component 8 is fixedly connected to the upper outer surface of the first connecting shaft 6 at equal angles. The left and right ends of the adjusting frame 9 are integrally connected to the connecting rod 10. The connecting rod 10 passes through the inside of the connecting ear 11. The bearing plate 12 is in a sliding structure on the upper side of the workbench 1 through the adjusting component 8 and the adjusting frame 9. Therefore, when the first motor 7 works, it drives the first connecting shaft 6 to rotate on the workbench 1. When the first connecting shaft 6 rotates, it drives the adjusting component 8, which is set at equal angles, to rotate. When the adjusting component 8, which is set at equal angles, rotates inside the adjusting frame 9, it contacts the inner wall of the adjusting frame 9. This allows the connecting rod 10, which is set symmetrically on the left and right, to slide left and right inside the connecting ear 11 at the corresponding position. Through the adjusting frame 9 and the bearing plate 12, it drives the storage bucket 13 to slide left and right on the upper side of the workbench 1, making the shaking of the concrete inside the storage bucket 13 more even, thus making the concrete inside the storage bucket 13 more compact and flat.

[0034] Example 3: Existing methods for adjusting the height of a concrete bucket use components such as a lead screw, moving sleeve, hinged rod, crank handle, connecting frame, limiting rod, limiting seat, and limiting groove. However, these methods are relatively complex. Therefore, this example uses the following technical solution: Figure 2 , Figure 4 and Figure 6 Since the guide rod 22 is nested inside the connecting hole 23, and the guide rod 22 is symmetrically fixed to the upper end of the base plate 21, the storage bucket 13 is in a lifting structure on the upper side of the base plate 21 through the guide rod 22 and the connecting hole 23. Therefore, when the second cylinder 20 works, it drives the worktable 1 to rise, so that the symmetrically arranged connecting holes 23 slide upward on the guide rod 22 at the corresponding position, making the worktable 1 rise more stably. When the first cylinder 3 works, it drives the mounting frame 4 to fall until the lower end of the test needle 5 contacts the upper end of the concrete inside the storage bucket 13. The mounting frame 4 is equipped with a pressure sensing mechanism. The pressure sensing mechanism senses and records the pressure received by the test needle 5 when it contacts the concrete inside the storage bucket 13, so that the staff can easily detect the setting time of the concrete by the change of pressure value, thus facilitating the adjustment of the height. The adjustment structure is simple and stable. All the electrical components mentioned above are existing technologies and will not be described in detail here.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
