Description

Technical Field

[0001] The utility model relates to the technical field of concrete experimental equipment, in particular to a novel stirring device. Background Art

[0002] Concrete is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. The term "concrete" generally refers to cement as the binder, sand and stone as aggregates, mixed with water in a specific proportion, and then mixed together. Cement concrete, also known as conventional concrete, is widely used in civil engineering. Dedicated mixers are required in laboratories, but the mixing heads of conventional mixers are difficult to clean, and incomplete cleaning can easily affect subsequent concrete mixing test data.

[0034] The design of the clamping mechanism can tightly fix the mixing barrel 3 to prevent it from shaking or displacement during the mixing process, thereby ensuring the accuracy and safety of the experiment.

[0035] Example 2

[0036] Reference Figure 1 and Figure 3-Figure 6 , a new stirring device, the clamping mechanism includes a third rotating motor 16, a transmission roller 17, a gear 18, a rack 19, a second movable plate 20, a connecting frame 21, a sliding plate 22, a clamping plate 23 and a spring 24, the third rotating motor 16 is fixed to the bottom end of the outer side of the rotating rod 8, the output end of the third rotating motor 16 is fixed to the transmission roller 17, the transmission roller 17 is rotatably connected to the rotating rod 8, one end of the outer side of the transmission roller 17 is fixed with a gear 18, the gear 18 is located on the inner side of the rotating rod 8, one side of the gear 18 is meshed with a rack 19, the rack 19 is slidably connected to the rotating rod 8, the bottom of the rack 19 is fixed with a second movable plate 20, the second movable plate 20 is slidably connected to the rotating rod 8;

[0037] Both ends of the inner side of the second movable plate 20 are rotatably connected to a connecting frame 21, and the connecting frame 21 is slidably connected to the rotating rod 8. A sliding plate 22 is fixed to one end of the connecting frame 21, and the sliding plate 22 is slidably connected to the rotating rod 8. A clamping plate 23 is fixed to one end of the sliding plate 22, and the clamping plate 23 is slidably connected to the rotating rod 8. The clamping plate 23 is clamped to the stirring head 9. A spring 24 is fixed to the other end of the sliding plate 22, and the spring 24 is located on the inner side of the rotating rod 8;

[0038] The snap-on mechanism enables the stirring head 9 to be quickly and conveniently removed from the rotating roller 8, and the stirring head 9 can be cleaned separately without the need to laboriously clean the entire equipment, which greatly improves the convenience of cleaning, avoids cross contamination between different materials, and ensures the purity of each stirring.

[0039] An annular groove 25 is provided on the inner side of the top of the stirring head 9, and the clamping plate 23 is clamped with the stirring head 9 through the annular groove 25. The opening of the annular groove 25 enables the rotating rod 8 and the stirring head 9 to be better connected. Two second guide plates 26 are fixed to the top end of the outer side of the stirring head 9. The setting of the annular groove 25 can make the stirring head 9 and the rotating rod 8 better installed, and at the same time, it can ensure that the stirring head 9 will not rotate inside the rotating rod 8, and the second guide plate 26 is clamped with the rotating rod 8; a controller 11 is fixed on the side of the first connecting plate 2 close to the second motor 10, and the controller 11 is electrically connected to the electric push rod 4, the first motor 7, the second motor 10 and the third rotating motor 16. The setting of the controller 11 can better operate the mixer.

[0040] The use process of the novel stirring device provided by the present invention is as follows: the stirring barrel 3 is placed between the two clamping plates 14, and the second motor 10 is started by the controller 11. The output end of the second motor 10 drives the bidirectional threaded rod 12 to rotate. Since the bidirectional threaded rod 12 is threadedly connected to the first movable plate 13, and the first movable plate 13 is slidably connected to the base 1, the rotation of the bidirectional threaded rod 12 drives the two first movable plates 13 to approach each other, so that the clamping plates 14 fixedly connected to the first movable plates 13 also move, and the two clamping plates 14 clamp the stirring barrel 3 on the base 1.

[0041] The clamping mechanism is designed to firmly secure the mixing barrel 3, preventing it from shaking or shifting during the mixing process, thereby ensuring the accuracy and safety of the experiment.

[0042] When the mixing barrel 3 is fixed, the controller 11 controls the telescopic end of the electric push rod 4 to drive the second connecting plate 5 to move, so that the stirring head 9 connected to the rotating rod 8 extends into the inner side of the mixing barrel 3. At this time, the controller 11 controls the first motor 7 to start, and the output end of the first motor 7 drives the rotating rod 8 to rotate, so that the stirring head 9 connected to the rotating rod 8 also rotates;

[0043] When the stirring is completed and the stirring head 9 needs to be cleaned, the controller 11 controls the third rotating motor 16, and the output end of the third rotating motor 16 drives the transmission roller 17 to rotate. Since the transmission roller 17 is fixedly connected to the gear 18, the rotation of the transmission roller 17 drives the gear 18 to rotate. Since the gear 18 is meshed with the rack 19, the rotation of the gear 18 drives the rack 19 to move downward, so that the second movable plate 20 fixedly connected to the rack 19 also moves downward. 20 is rotatably connected to the connecting frame 21, the connecting frame 21 is fixedly connected to the sliding plate 22, and the sliding plate 22 is slidably connected to the rotating rod 8, so that the movement of the second movable plate 20 pushes the sliding plate 22 to move through the connecting frame 21, so that the spring 24 fixed to the sliding plate 22 is compressed as the sliding plate 22 moves, and at the same time, the clamping plate 23 fixed to the sliding plate 22 also moves. As the clamping plate 23 moves, the clamping plate 23 is no longer clamped with the stirring head 9 through the annular groove 25, and the stirring head 9 can be removed for cleaning;

[0044] The snap-on mechanism enables the stirring head 9 to be quickly and conveniently removed from the rotating roller 8, and the stirring head 9 can be cleaned separately without the need to laboriously clean the entire equipment, which greatly improves the convenience of cleaning, avoids cross contamination between different materials, and ensures the purity of each stirring.
