Description

Technical Field

[0001] The utility model relates to the technical field of powdery material sampling, in particular to a device for improving the sampling efficiency of powdery materials. Background Art

[0002] The market demand for fly ash is constantly increasing, especially during seasons when fly ash supply is tight, resulting in a shortage. To meet demand and maximize economic benefits, suppliers source from a wide range of sources, resulting in inconsistent quality. Some even combine different grades of fly ash, with the upper portion of shipping tankers filled with qualified fly ash and the lower portion with inferior fly ash. Overseeing fly ash quality is extremely difficult, as inconsistent fly ash can easily lead to significant physical losses and quality disputes during concrete production, such as broken piles, cracks, and cosmetic defects. Currently, samplers vary in quality, and their insertion depth is significantly affected by the density of the cement and fly ash, resulting in a severely insufficient insertion depth, making it impossible to effectively represent the middle and lower samples.

[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-4 As shown, a device for improving the sampling efficiency of powdery materials includes an outer cylinder 1 and an inner cylinder 2. The outer cylinder is a cylindrical structure with open top and bottom, and a plurality of sampling ports 3 are opened on its surface from top to bottom. The inner cylinder 2 is an arc-shaped plate structure with open top and bottom. The top of the outer cylinder 1 is fixedly connected to the inner ring of the mounting ring 4, and a support ring 5 is fixedly provided on the surface of the mounting ring 4. A rotating motor 6 is laterally provided on the side wall of the support ring 5, and an eccentric wheel 7 is vertically installed on the output shaft of the rotating motor 6.

[0019] Preferably, the bottom of the outer cylinder 1 is threadedly engaged with the top of the conical head 8. The conical head 8 can make it easier for the outer cylinder 1 to drill into the sample. At the same time, the conical head 8 and the bottom of the outer cylinder 1 are threadedly engaged to achieve a detachable connection process for easy replacement.

[0020] Preferably, the top of the inner cylinder 2 is fixedly connected to the bottom of the mounting plate 9, and the outer edge of the mounting plate 9 is fixedly connected to the end of the rotating rod 10. This design facilitates the rotation of the mounting plate 9 by the rotating rod 10, thereby rotating the inner cylinder 2 within the outer cylinder 1, thereby closing and opening the injection port 3.

[0021] Preferably, a limiting rod 11 is provided at the bottom of the mounting plate 9 to cooperate with the support ring 5. Since the entire device vibrates when the rotary motor 6 drives the eccentric wheel 7 to rotate, in order to prevent the inner cylinder 2 from deflecting within the outer cylinder 1, the limiting rod 11 at the bottom of the mounting plate 9 can be inserted into the support ring 5, thereby preventing the inner cylinder 2 from rotating with the vibration. Therefore, the support ring 5 here serves two functions: one is to fix the rotary motor 6, and the other is to limit the position of the limiting rod 11.

[0022] Preferably, four support rings 5 ​​are fixedly mounted on the surface of the mounting ring 4, and the four support rings 5 ​​are distributed in a circular array on the surface of the mounting ring 4. With this design, the mounting rings 4 are evenly distributed, and when the four rotary motors 6 drive the corresponding eccentric wheels 7 to rotate, the entire device vibrates more stably and is less likely to tilt in one direction. In addition, the four rotary motors 6 in this embodiment can be connected in parallel and then controlled by the same switch. The four eccentric wheels 7 have the same starting position, so that when the four rotary motors 6 are turned on, the four eccentric wheels 7 rotate synchronously and in phase, avoiding the phenomenon of vibration forces being weakened due to phase inconsistency.

[0023] Preferably, an operating rod 12 is fixedly provided on the outer edge of the mounting ring 4. The operating rod 12 applies force to the mounting ring 4, thereby pressing the outer cylinder 1 to facilitate sampling.

[0024] Preferably, the outer diameter of the inner cylinder 2 is consistent with the inner diameter of the outer cylinder 1 .

[0025] Preferably, a plurality of separation plates 13 are provided on the inner side of the inner cylinder 2 from top to bottom, corresponding to the sampling ports 3. After the separation plates 13 are provided, powdery materials at different depths can be sampled. In this way, after powdery materials at different depths enter the outer cylinder 1, they can be separated by the separation plates 13 and are not easily mixed with each other, thereby meeting the needs of sampling at different depths.

[0026] Preferably, the rotating motor 6 in this embodiment is a micro motor structure, and the eccentric wheel 7 is an elliptical cylindrical structure, and its two side areas are connected to the output shaft of the rotating motor 6. When the rotating motor 6 is working, the eccentric wheel 7 rotates and causes the entire device to vibrate, which is similar to the structure of a vibration motor.

[0027] The working principle of this embodiment is as follows:

[0028] Before sampling, first install the conical head 8 to the bottom of the outer cylinder 1, then insert the inner cylinder 2 into the outer cylinder 1, and rotate the angle of the inner cylinder 2 so that the inner cylinder 2 just covers the sampling port 3 on the surface of the outer cylinder 1. At this time, insert the limiting rod 11 at the bottom of the mounting plate 9 into the supporting ring 5 to prevent the inner cylinder 2 from rotating with the vibration; start the rotating motor 6, and the rotating motor 6 drives the eccentric wheel 7 to rotate when it rotates. Since the center of the eccentric wheel 7 deviates from the output shaft of the rotating motor 6, vibration will occur, and the whole device will vibrate. Insert the conical head 8 at the bottom of the outer cylinder 1 into the sampling area, and press the operating rod 12 by hand at the same time. Apply force to the mounting ring 4 through the operating rod 12, so that the outer cylinder 1 can be pressed. While the outer cylinder 1 is vibrating, the outer cylinder 1 can be easily inserted into the sample under the action of the pressing force. When the required depth is reached, the rotating motor 6 is turned off, and the mounting disk 9 is pulled upward for a short distance so that the limiting rod 11 at the bottom leaves the support ring 5. Then the mounting disk 9 is rotated to make the inner cylinder 2 leave the sampling port 3 on the surface of the outer cylinder 1, and the powdered sample enters the outer cylinder 1 along the sampling port 3. Then the mounting disk 9 is rotated again so that the inner cylinder 2 blocks the sampling port 3 on the surface of the outer cylinder 1. The entire device is pulled out from the powdered sample and then placed flat on the table. The arc groove of the inner cylinder 2 is located at the bottom of the outer cylinder 1. The inner cylinder 2 is pulled out from the outer cylinder 1 horizontally, so that the sample leaves the outer cylinder 1 along with the inner cylinder 2 to obtain the sample.

The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
