[0027] Please refer to Figures 1 to 4 The embodiment of the present application provides a powder density measuring feeder, which comprises a main body part 1, a top cover 2, a rotating handle 3, a blade 4. Wherein, the main body part 1 is funnel-shaped, the bottom end of the main body part 1 is provided with a discharge port 11, the top of the main body part 1 is provided with an open end 12, the outer diameter of the discharge port 11 is smaller than the inner diameter of the neck of the Lee's specific gravity bottle 5. The top cover 2 is covered on the open end 12 of the main body. The rotating handle 3 is rotatably arranged on the top cover 2. The blade 4 is fixed on the rotating handle 3, and the blade 4 is located in the main body part 1.

[0028] The powder density measuring feeder provided by the utility model is used, the discharge port 11 of the main body part 1 is inserted into the neck of the Lee's specific gravity bottle 5, then the powder (such as cement) to be added into the Lee's specific gravity bottle 5 for measurement is poured into the main body part 1, finally the top cover 2 is covered, the blade 4 in the main body part 1 is rotated by shaking the rotary handle 3, when the blade 4 rotates, the powder in the main body part 1 is agitated, so that the powder is output from the bottom discharge port 11, and the powder in the main body part 1 can continuously enter the Lee's specific gravity bottle 5 through the discharge port 11 (such as Figures 3-4 ). Since the mouth of the Lee's specific gravity bottle 5 is small, the traditional feeding mode is to add a little bit into the Lee's specific gravity bottle 5 by a small spoon, the feeding process is complicated, and the powder is easy to be lost outside, which leads to the loss of the powder. The powder density measuring feeder in the utility model can optimize the feeding process, when feeding, only the rotary handle 3 is shaken, and the feeding can be continuously carried out, compared with the feeding mode by the small spoon, it is more relaxed, and the top cover 2 can prevent the powder in the main body part 1 from leaking out, and the powder is prevented from being lost.

[0029] In one embodiment, the rotary handle 3 is installed on the top cover 2 through the bearing 7. The installation mode of the bearing 7 makes the rotary handle 3 more smooth in the rotating process, reduces the friction resistance, and improves the use comfort and durability of the feeder. Meanwhile, the stability of the bearing 7 also guarantees the reliability of the rotary handle 3 in the long-time use process.

[0030] In one embodiment, the blade 4 is close to the inner wall of the main body part 1. The design that the blade 4 is close to the inner wall can more effectively scrape the powder on the inner wall of the main body part 1, ensures that the powder can completely enter the Lee's specific gravity bottle 5 through the discharge port 11, reduces the residue and loss of the powder, and improves the feeding efficiency of the feeder.

[0031] In one embodiment, the main body part 1 and the blade 4 are made of a material that does not adhere to the powder. The material that does not adhere to the powder can effectively prevent the powder from adhering to the main body part 1 and the blade 4, reduce the difficulty and time of cleaning, improve the use convenience and hygiene of the feeder. Meanwhile, the problem that the feeding is inaccurate due to the adhesion of the powder is also avoided.

[0032] Specifically, the material that does not adhere to the powder is polytetrafluoroethylene or modified polysiloxane. The polytetrafluoroethylene and the modified polysiloxane are both materials with good non-stick properties, and the selection of the materials further guarantees the non-stick performance of the feeder. These materials also have the characteristics of corrosion resistance and wear resistance, and improve the service life of the feeder.

[0033] In one embodiment, the edge of the bottom discharge port 11 of the main body part 1 is provided with a chamfer or a round corner. Then the accumulation and blockage of the powder at the discharge port 11 can be reduced, and the powder can flow into the Lee's specific gravity bottle 5 more smoothly.

[0034] AsFigure 4 The inner diameter of the discharge port 11 is gradually increased from top to bottom, so that the powder entering the discharge port 11 can smoothly fall into the Lee specific gravity bottle 5 below and is not easily blocked in the discharge port 11.

[0035] In one embodiment, a clamping groove structure is arranged between the top cover 2 and the main body 1. Specifically, a groove is arranged on the top of the main body 1, and the bottom surface of the top cover 2 is provided with a protrusion matched with the groove. When the top cover 2 is buckled on the top of the main body 1, the protrusion of the top cover 2 is clamped and fixed in the groove of the main body 1, so that when the rotating handle is shaken, the top cover is not easy to rotate with the rotating handle.

[0036] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
