Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0022] Embodiment 1 of this utility model

[0023] Reference Figure 1 and Figure 2 A powdered material sample collection device includes a finished product chute 1, a conveying pipe 2, and a powder recovery tank 3. The finished product chute 1 is installed at the bottom of the finished product silo in a finished product warehouse. The powder recovery tank 3 is located outside the finished product warehouse. A sampling tube 11 is fixed at the bottom of the finished product chute 1, and the conveying pipe 2 is installed below the sampling tube 11. A pneumatic sampler 12 is fixed between the conveying pipe 2 and the sampling tube 11. One end of the conveying pipe 2, away from the pneumatic sampler 12, extends out of the finished product warehouse and is fixed to the powder recovery tank 3. The pneumatic sampler 12 can extract the material in the finished product chute 1 into the conveying pipe 2. A support frame 13 is installed below the powder recovery tank 3, and the powder recovery tank 3 is fixed on the support frame 13.

[0024] A vibratory motor 31 is fixed to the side wall of the powder recovery tank 3, and a connecting pipe 32 is fixed to the bottom of the powder recovery tank 3. A sampling bucket 4 is installed below the connecting pipe 32 and is threadedly connected to the connecting pipe 32. A valve 33, which is an electric butterfly valve, is installed on the connecting pipe 32. An exhaust pipe 5 is fixed to the side wall of the powder recovery tank 3, and a Roots blower 51 is installed on the exhaust pipe 5. The height of the exhaust pipe 5 near the powder recovery tank 3 is higher than the height of the conveying pipe 2 near the powder recovery tank 3.

[0025] Since the powder recovery tank 3 is located outside the finished product warehouse, staff do not need to frequently pass through the truck lane to take samples, which reduces the possibility of staff colliding with trucks and ensures the safety of staff during the sampling process.

[0026] The implementation principle of the powdered material sample collection device in Embodiment 1 of this utility model is as follows: During sampling, negative pressure is generated by the Roots blower 51, and the pneumatic sampler 12 removes the material from the finished product chute 1. The material reaches the conveying pipe 2, and the negative pressure is used to transport the material in the conveying pipe 2 to the powder recovery tank 3. Then, the valve 33 and the vibrating motor 31 are opened, causing the material in the powder recovery tank 3 to fall into the sampling bucket 4. Then, the sampling personnel rotate and unscrew the sampling bucket 4.

[0027] Embodiment 2 of this utility model

[0028] Reference Figure 3 and Figure 4 The difference from Embodiment 1 lies in the connection method between the connecting tube 32 and the sampling bucket 4. Two connecting vertical plates 6 are provided on the outer wall of the connecting tube 32, and the two connecting vertical plates 6 are symmetrically arranged about the axis of the connecting tube 32. The connecting vertical plates 6 include a first connecting vertical plate 61 and a second connecting vertical plate 62. The first connecting vertical plate 61 is located above the second connecting vertical plate 62, and a connecting horizontal plate 64 is fixed to the top of the first connecting vertical plate 61. The connecting horizontal plate 64 is fixed to the outer wall of the connecting tube 32.

[0029] The bottom of the first connecting vertical plate 61 is provided with a plug hole 611, and a spring 612 is provided in the plug hole 611. The top of the second connecting vertical plate 62 is inserted into the plug hole 611. One end of the spring 612 is fixed to the top of the second connecting vertical plate 62, and the other end of the spring 612 is fixed to the wall of the plug hole 611 away from the second connecting vertical plate 62.

[0030] A supporting horizontal plate 63 is fixed to the bottom of the second connecting vertical plate 62, and the supporting horizontal plate 63 is located on the side of the second connecting vertical plate 62 closest to the connecting pipe 32. Two connecting plates 7 are fixed to the side wall of the sampling bucket 4, and the two connecting plates 7 are symmetrically arranged about the axis of the sampling bucket 4. When the sampling bucket 4 is installed on the connecting pipe 32, the supporting horizontal plate 63 is pulled down so that the height of the supporting horizontal plate 63 is lower than the bottom of the connecting pipe 32. Then, the connecting plates 7 of the sampling bucket 4 are placed on the supporting horizontal plate 63, so that the opening of the sampling bucket 4 is aligned with the feed pipe. The sampling bucket 4 is released, and under the action of the spring 612, the sampling bucket 4 moves upward, and the opening of the sampling bucket 4 fits into the bottom of the connecting pipe 32. When the material in the powder recovery tank 3 falls into the sampling bucket 4, the weight of the sampling bucket 4 increases, and the sampling bucket 4 gradually moves downward. After the sampling bucket 4 is full of material, the top of the sampling bucket 4 does not detach from the bottom of the connecting pipe 32. Once the sampling bucket 4 is full, the staff pulls the sampling bucket 4 downwards to detach it from the connecting pipe 32 and moves it outwards, thus facilitating the installation and removal of the sampling bucket 4.

[0031] Embodiment 3 of this utility model

[0032] Reference Figure 5 and Figure 6 The difference from Embodiment 1 lies in the connection method between the connecting tube 32 and the sampling bucket 4. A connecting hose 34 is fixed below the connecting tube 32, and a base 8 is provided below the connecting hose 34. The base 8 includes a bottom frame 81 placed on the ground. Support rods 82 are fixed at the four corners of the bottom frame 81, and a top plate 83 is fixed at the top of the support rods 82. A connecting sleeve 831 is fixed above the top plate 83, and a discharge hole is provided on the top plate 83, which is aligned with the connecting sleeve 831. The end of the connecting hose 34 away from the connecting tube 32 enters and exits into the connecting sleeve 831.

[0033] A lifting plate 9 is installed above the bottom frame 81. Two connecting rods 91 are fixed on the lifting plate 9, extending upwards through the top plate 83. The connecting rods 91 can move up and down. A connecting ring 92 is fixed to the top of the connecting rod 91. A lifting rod 93 is installed between the two connecting rings 92, with both ends of the lifting rod 93 passing through the corresponding connecting rings 92. Nuts are threaded onto both ends of the lifting rod 93. The lifting rod 93 can rotate along the axis of the connecting rings 92. A positioning block 94 is fixed at the middle position of the lifting rod 93. The positioning block 94 is cylindrical and eccentrically positioned relative to the lifting rod 93. A toggle rod 95 is fixed on the positioning block 94. The positioning block 94 is in contact with the upper surface of the top plate 83.

[0034] The sampling bucket 4 is placed on the lifting plate 9, which is at its lowest position. The top of the sampling bucket 4 needs to contact the bottom of the top plate 83. The actuating lever 95 is rotated, causing the positioning block 94 to rotate. During this rotation, the connecting rod 91 is lifted upwards. When the actuating lever 95 is in a horizontal position, the positioning block 94 remains stationary due to the friction between it and the upper surface of the top plate 83. Then, the valve 33 is opened, and the material falls into the sampling bucket 4.

[0035] When the sampling bucket 4 is full, rotate the lever 95 upward to move the connecting rod 91 downward, thereby moving the lifting plate 9 downward. After the sampling bucket 4 is separated from the top plate 83, the sampling bucket 4 can be taken out.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
