[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] See also Figures 1 to 8, is a new type of powder feeder as the best embodiment of the utility model, including a silo 10 and a feeding screw 20. A storage chamber 101 and a feeding chamber 102 are arranged in sequence from top to bottom along the central axis direction of the silo 10. The silo 10 is made of metal, and the inner wall of the feeding chamber 102 is cylindrical, that is, the cross section in the direction perpendicular to the central axis is circular. A feeding channel 103 is arranged between the feeding chamber 102 and the storage chamber 101. The feeding screw 20 is rotatably arranged in the feeding chamber 102, that is, it rotates along the central axis direction of the silo 10, and a feeding channel is formed between the feeding screw 20 and the inner wall of the feeding chamber 102. When taking materials, the feeding screw 20 is rotated counterclockwise to drive the powder to move upward along the feeding channel, and then the powder enters the storage chamber 101 through the feeding channel 103. The material extractor of the utility model can bring up powder materials in a deep layer by rotating the material extracting screw 20 counterclockwise, thereby achieving the effect of deep-layer material extracting and being easy to operate.

[0032] Please refer to Figure 4 The outer wall of the feeding screw 20 is provided with a spiral thread groove 21, and the thread groove 21 and the inner wall of the feeding cavity 102 form a feeding channel. The bottom end of the feeding screw 20 is provided with a tapered portion. When the feeder wants to take deep materials, the powder material can be easily pushed away by rotating the feeding screw 20 to reach the desired feeding position.

[0033] Please refer to Figure 1-3 , the material extractor also includes a driving member 30 that passes through the storage chamber 101 and is connected to the material extracting screw 20 in the feeding chamber 102. The driving member 30 rotates to drive the material extracting screw 20 located in the feeding chamber 102 to rotate. During operation, the driving member 30 is manually rotated to drive the material extracting screw 20 to rotate. A sleeve 40 is provided on the upper end surface of the silo 10 along the central axis direction thereof. The sleeve 40 is hollow and communicated with the inside of the storage chamber 101. When extracting materials, it is convenient to hold the sleeve 40 to achieve stable material extraction and convenient operation. The length of the driving member 30 and the sleeve 40 of the utility model are set as required. One end of the driving member 30 is connected to the material extracting screw 20, and the other end passes through the storage chamber 101 and the sleeve 40 in sequence and extends out of the sleeve 40. The extending part of the driving member 30 is provided with a hand-held portion, which can be a sphere, and the hand-held portion is provided with anti-slip patterns to prevent slipping during operation. During operation, one hand holds the shaft sleeve 40 and the other hand holds the hand-held non-rotating driving member 30. When the material picker is inserted into the material, the driving member 30 is rotated clockwise to drive the material picking screw 20 to rotate, and the upper layer of powder material is moved to prevent the upper layer of material from entering the feeding channel. When the material picking position is reached, the shaft sleeve 40 is held still by hand, and then the driving member 30 is rotated counterclockwise to drive the material picking screw 20 to rotate counterclockwise. The powder material enters the feeding chamber 102 as the material picking screw 20 rotates counterclockwise.

[0034] like Figure 5 As shown, a partition 11 perpendicular to the inner wall of the silo 10 is provided, and a storage cavity 101 and a feeding cavity 102 are formed by the partition 11. A feeding channel 103 is provided on the partition 11, and a sealing plate 50 adapted thereto is provided on the feeding channel 103. One side of the sealing plate 50 is rotatably connected to a side wall of the feeding channel, and the side opposite to the rotation can be opened upward away from the feeding channel. Specifically, a connecting portion 51 connected to the upper end surface of the feeding channel 103 is provided on one side of the upper end surface of the sealing plate 50, so that the sealing plate 50 automatically closes the feeding channel 103 and can only be opened toward the storage cavity 101. An avoidance groove 52 is provided at the edge where the connecting portion 51 is connected to the upper end surface of the partition 11, so that the sealing plate 50 can rotate more smoothly. The sealing plate 50 is a rubber part, that is, the material is rubber material. When the powder material enters the feeding chamber 102 and reaches a certain amount, the powder pushes the sealing plate 50 upward, so that the powder enters the storage chamber 101 through the feeding channel 103, and then the sealing plate 50 automatically falls back to its original position to close the feeding channel 103. By providing the sealing plate 50, the powder in the storage chamber 101 can be prevented from falling into the feeding chamber 102 through the feeding channel 103.

[0035] like Figure 6 , 8 As shown, a discharge port 12 communicating with the interior of a material storage chamber 101 is provided on the outer side of the silo 10, and a bin door 60 rotatably connected to the silo 10 is provided at the discharge port 12. When taking materials, the bin door 60 is located in the discharge port 12 to prevent other materials from entering or dust from falling out. Specifically, a cylindrical support column 61 is provided on one side of the bin door 60, and a cylindrical rotating shaft 62 is provided below the support column 61. A connecting sleeve 13 cooperating with the rotating shaft 62 is provided on the silo 10 and located at the discharge port 12. In order to prevent the bin door 60 from opening automatically, a damping sleeve is provided between the outer wall of the rotating shaft 62 and the inner wall of the connecting sleeve 13. The damping sleeve is a wear-resistant part made of polyformaldehyde, or a magnet 80 is embedded on the side of the bin door 60 away from the rotating shaft 62. The silo 10 is made of a magnetically absorbable metal material, and the silo 10 can be attracted by the magnet 80. A groove 63 is also provided on the surface of the bin door 60 to facilitate opening the bin door 60.

[0036] Please refer to Figure 4A vertically placed cleaning device 70 is provided on the outer wall of the driving member 30, and the cleaning device 70 is located in the storage bin 10. When the powder is taken out and poured out, some powder will inevitably adhere to the inner wall of the storage chamber 101. Therefore, the driving member 30 can be rotated to drive the cleaning device 70 to clean the powder in the storage bin 10 to avoid residue; the cleaning device 70 includes a support plate 71 provided on the outer wall of the driving member 30, and a cleaning brush 72 provided on the side of the support plate 71 and perpendicular to the side wall. A gap is formed between the outer edge of the support plate 71 and the inner wall of the storage bin 10, which not only reserves a gap for installing the cleaning brush 72, but also prevents the sealing plate 50 from being in an open state from interfering with the cleaning device 70 when the powder enters the storage bin 10.

[0037] The working principle of the new powder feeder of the utility model is as follows: when feeding, one hand holds the shaft sleeve 40 and the other hand holds the hand-held part, firstly rotates the feeding screw 20 clockwise, and the powder material is pushed away by the conical part at the bottom of the feeding screw 20. When the required feeding depth is reached, the hand holds the shaft sleeve 40 and keeps it still, and then rotates the feeding screw 20 counterclockwise. The powder enters the feeding channel along with the counterclockwise rotation of the feeding screw 20. When the amount of powder in the feeding channel reaches a certain amount, the sealing plate 50 will be pushed toward the powder. The top is opened, and the powder enters the storage chamber 101 through the feeding channel 103. After taking out, the sealing class automatically falls back and closes. The taken powder is located in the storage chamber 101, and the entire material taker is pulled upward. The bin door 60 is opened to pour out the taken powder. At the same time, in order to clean the powder in the storage chamber 101 as much as possible, the driving part 30 can be rotated to drive the cleaning device 70 to rotate, and the powder in the storage chamber 101 is cleaned and poured out together through the bin door 60; after pouring out, the bin door 60 is closed to carry out the next material taking.

[0038] In summary, the utility model is a novel powder material extractor, which can bring up the powder material in the deep layer through the rotation of the material extracting screw, so as to achieve the effect of deep material extracting and is easy to operate. At the same time, the material can be prevented from being contaminated by external objects through the setting of the sealing plate.

[0039] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
