[0009] Further, it is worth noting that a counterweight is provided at the bottom of the side of the support frame away from the material storage container.

[0010] It should be noted that the material storage container and the support frame are separately arranged in the solution.

[0011] As a preferred implementation manner, the material storage container is arranged on the fixed seat through a shock absorption assembly.

Detailed implementation manners

[0019] In order to enable those skilled in the art of this technology to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings.

[0020] The core of this application is to provide an abrasive bulk density measurement device, which solves the problems that when measuring the bulk density by manual feeding at present, due to the inconsistent manual feeding speed, and when introducing abrasive powder into the material receiving container through the discharge pipe under the feed hopper, there will be a situation where there is less raw material accumulation around and more raw material accumulation in the middle, and the accuracy and repeatability of the measurement results are not particularly persuasive.

[0021] Figure 1 It is a schematic structural diagram of an abrasive bulk density measurement device provided by the present utility model. Figure 2 It is a sectional view of an abrasive bulk density measurement device provided by the present utility model. See Figures 1 to 2 as shown.

[0022] An abrasive bulk density measuring device includes a support frame 1. Inside the upper part of the support frame 1, there is a support cross plate 2, and the support frame 1 supports and fixes the support cross plate 2. A feed hopper 3 is penetrated through the support cross plate 2. The feed hopper 3 is conical. The powder to be measured is added through the top of the feed hopper 3. A material scattering component 4 is arranged inside the feed hopper 3. The material scattering component 4 can break up the agglomerated abrasive powder and make the powder fall evenly. In order to further simulate the free fall of the powder and ensure smooth feeding, buffer components 5 are arranged on both sides of the bottom of the support cross plate 2. The lower ends of the two buffer components 5 are jointly provided with a blanking plate 6. A blanking cylinder 8 is penetrated through the blanking plate 6. The blanking cylinder 8 is located below the feed hopper 3. A receiving container 11 is arranged directly below the blanking cylinder 8. The abrasive powder broken by the material scattering component 4 falls evenly into the blanking cylinder 8 on the blanking plate 6. The buffer component 5 drives the blanking plate 6 to vibrate slightly, and then makes the blanking cylinder 8 vibrate slightly. As a preferred embodiment, a material scattering plate 9 is arranged inside the blanking cylinder 8. Material scattering holes 10 are evenly opened on the material scattering plate 9. Through the material scattering plate 9, it can effectively prevent the unbroken lump materials from falling into the receiving container 11, make the powder fall freely into the receiving container 11, avoid the situation that there is less raw material accumulated around the receiving container 11 and more raw material accumulated in the middle, and can measure the abrasive bulk density more accurately.

[0023] In this embodiment, as a preferred embodiment, the material scattering component 4 includes a bracket 401 fixedly connected to the inner surface of the feed hopper 3. A motor 402 is fixedly connected to the middle of the bracket 401 through a fixed sleeve. The bottom end of the output shaft of the motor 402 is fixedly connected with a stirring rod 403. When the powder needs to be measured, the abrasive powder is added into the feed hopper 3, and the motor 402 is started. The stirring rod 403 is driven by the motor 402 to rotate at a constant speed. On the one hand, the agglomerated powder can be broken by the stirring rod 403 to prevent the agglomerated powder from falling into the receiving container 11 and affecting the measurement result. On the other hand, the rotating stirring rod 403 can make the powder fall more evenly into the blanking cylinder 8.

[0024] In order to fully simulate the free fall of the powder material, as a preferred embodiment, the buffer assembly 5 includes a connecting plate 501, a spring 502, and a connecting rod 503. The connecting plate 501 is installed at the inner top end of the support cross plate 2. A cavity is formed inside the connecting plate 501. The spring 502 is installed inside the cavity. The connecting rod 503 is installed at the bottom end of the spring 502. The bottom end of the connecting rod 503 penetrates through the cavity and is connected to the blanking plate 6. Preferably, a vibrator 7 is provided at the bottom of the blanking plate 6. The powder material uniformly falls onto the blanking plate 9 inside the blanking cylinder 8 through the feed hopper 3 and the material scattering assembly 4. At this time, the vibrator 7 operates to drive the blanking plate 9 to vibrate through the connecting rod 503 and the spring 502. The slight vibration enables the powder material on the blanking plate 9 to spill out from the material scattering holes 10. When the powder material passes through the material scattering holes 10 of the blanking plate 9, it is uniformly dispersed and then falls downward, so that the powder material can freely fall and accumulate inside the material receiving container 11.

[0025] In order to ensure the stability of the device, as a preferred embodiment, a counterweight 14 is provided at the bottom of one side of the support frame 1 away from the material receiving container 11. Arranging the counterweight 14 for the support frame 1 can effectively ensure the stability of the device and further ensure the test accuracy.

[0026] In this embodiment, as a preferred embodiment, the material receiving container 11 and the support frame 1 are separately arranged, and there is no fixed connection relationship between them, and the vibrations between them cannot be transmitted to each other. Further, the material receiving container 11 is arranged on the fixed seat 13 through a shock absorption assembly, effectively avoiding the vibration on the funnel being transmitted to the material receiving container 11, resulting in the phenomenon of powder material vibration in the material receiving container, and can further ensure the accuracy of the bulk density test.

[0027] The working principle of the abrasive bulk density measuring device provided by this application is as follows: When it is necessary to measure the powder material, the ground powder is added into the feed hopper 3, and the motor 402 is started. The stirring rod 403 is driven by the motor 402 to rotate at a constant speed. On the one hand, the agglomerated powder material can be broken by the stirring rod 403, avoiding the agglomerated powder material falling into the material receiving container 11 and affecting the measurement result. On the other hand, the rotating stirring rod 403 can make the powder material fall into the blanking cylinder 8 more uniformly; the powder material uniformly falls onto the blanking plate 9 inside the blanking cylinder 8 through the feed hopper 3 and the material scattering assembly 4. At this time, the vibrator 7 operates to drive the blanking plate 9 to vibrate through the connecting rod 503 and the spring 502. The slight vibration enables the powder material on the blanking plate 9 to spill out from the material scattering holes 10. When the powder material passes through the material scattering holes 10 of the blanking plate 9, it is uniformly dispersed and then falls downward, so that the powder material can freely fall and accumulate inside the material receiving container 11.

[0028] Other embodiments of the present application will be readily contemplated by those skilled in the art upon consideration of the specification and practice of the application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field disclosed in the present application. The specification and examples are only regarded as exemplary, and the true scope of the present application is pointed out by the claims.

[0029] It should be understood that the present application is not limited to the exact structures already described and shown in the drawings, and various modifications and changes can be made without departing from its scope. The embodiments of the present application described above do not constitute a limitation on the protection scope of the present application.
