Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figure 1-3As shown, a high-precision automatic powder sampling device includes a main body 1. The main body 1 is equipped with a discharge pipe 2, a cylinder 3, and a through groove 4. The discharge pipe 2 is welded to the front bottom of the main body 1. The cylinder 3 is fixed to the rear end of the main body 1 by screws. The through groove 4 is located in the middle of the main body 1, and a sampling tube 5 is nested in the through groove 4. The sampling tube 5 is equipped with a docking plate 6, a sliding groove 7, and a receiving groove 8. The docking plate 6 is welded to the rear end of the sampling tube 5, and the rear end of the docking plate 6 is fixedly connected to the piston rod of the cylinder 3 by screws. The sliding groove 7 is located in the middle of the top of the sampling tube 5, and the receiving groove 8 is located at the front end of the sampling tube 5. A fixing shaft 9 is nested in the sliding groove 7, and the upper end of the fixing shaft 9 passes through... The fixed shaft 9 is fixedly connected to the top wall of the through groove 4 by screws, and the lower end of the fixed shaft 9 passes through and extends to the inner end of the slide groove 7. The limiting shaft 10 is fixed by screws. The storage groove 8 is provided with a transmission hole 11, a through hole 12 and a sampling box 13. The transmission hole 11 is symmetrically opened on both sides of the rear end of the storage groove 8, and the through hole 12 is opened in the middle of the rear end of the storage groove 8. The sampling box 13 is placed in the storage groove 8. The transmission shaft 14 is fixedly installed on both sides of the rear end of the sampling box 13 by screws. The rear end of the transmission shaft 14 passes through and extends to the rear end of the transmission hole 11. A spring 15 is fitted between the transmission shaft 14 and the rear end of the transmission hole 11. The size and position of the through hole 12 and the limiting shaft 10 are symmetrical.

[0016] Specific usage: The main body 1 is installed and fixed on the powder conveying pipe. When it is necessary to sample the powder, the cylinder 3 is started to drive the sampling tube 5 to move forward in a straight line along the through groove 4 into the powder conveying pipe. At this time, the sampling box 13 collects the powder. Then the cylinder 3 is closed to drive the sampling tube 5 to move backward in a straight line along the through groove 4. The backward movement of the sampling tube 5 drives the sampling box 13 to move into the through groove 4. At this time, the sampling box 13 moves backward and contacts the limiting shaft 10 on the fixed shaft 9. Under the obstruction of the limiting shaft 10, the sampling box 13 moves forward along the transmission hole 11. The forward movement of the sampling box 13 compresses the spring 15 and moves out of the collection groove 8. After the sampling box 13 is moved out, the powder inside falls into the discharge pipe 2.

[0017] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
