[0028] Please see Figures 1-5 The diagram shows a structural schematic of an embodiment of the screw feeder for conveying feed according to this utility model. Please refer to [link / reference]. Figures 1-5 This paper provides a detailed description of a screw feeder for conveying feed.

[0029] A screw feeder for conveying feed includes a base 100 and a feeding hopper 200;

[0030] A mounting shell 101 is hinged to the top of the base 100. An inclined feeding pipe 102 is fixedly installed on the side wall of the mounting shell 101. The bottom of the feeding pipe 102 is hinged to one end of a telescopic rod 103, and the other end of the telescopic rod 103 is hinged to the top of the base 100. A spiral feeding rod 104, which is in the same direction as itself, is rotatably installed on the inner side of the feeding pipe 102 through a sealed bearing. An inlet pipe 105 is fixedly installed at the top of the lower end of the feeding pipe 102, and an outlet pipe 106 is fixedly installed at the bottom of the higher end of the feeding pipe 102. The inner cavities of the inlet pipe 105 and the outlet pipe 106 are connected to the inner cavity of the feeding pipe 102. The angle of the feeding pipe 102 can be adjusted by hinged connection between the base 100 and the mounting shell 101, in conjunction with the telescopic rod 103, thereby improving the flexibility of use.

[0031] The hopper 200 is fixedly mounted at the top of the feed pipe 105, and the two are connected internally. A hollow fixed shell 201 is fixedly mounted inside the hopper 200. A vertical first stirring rod 202 is rotatably mounted through the upper and lower walls of the fixed shell 201 via sealed bearings. Multiple layers of first stirring blades 203 are fixedly mounted around the shaft of the first stirring rod 202 from top to bottom. A symmetrical second stirring rod 204, perpendicular to the first stirring rod 202, is rotatably mounted through the side wall of the fixed shell 201 via sealed bearings. Multiple layers of second stirring blades 205 are fixedly mounted around the shaft of the second stirring rod 204 from the outside of the fixed shell 201 towards the inside of the hopper 200. The axial angle between the first stirring blade 203 and the second stirring blade 205 is 80° to 90°. The first stirring rod 202 is fixedly provided with a first bevel gear 206 at the position of the rod body located in the inner cavity of the fixed shell 201. The second stirring rod 204 is fixedly provided with a second bevel gear 207 meshing with the first bevel gear 206 at one end located in the inner cavity of the fixed shell 201. The first stirring rod 202 and the second stirring rod 204 in the hopper 200 are driven by the first bevel gear 206 and the second bevel gear 207. The axial angle between the first stirring blade 203 and the second stirring blade 205 is 80° to 90°, which can stir the feed from different directions, which helps to reduce feed clumping and promotes the smooth entry of feed into the feed pipe 105.

[0032] Furthermore, the telescopic rod 103 is one of an electric telescopic rod, a hydraulic telescopic rod, or a pneumatic telescopic rod. The manufacturer can design it according to the requirements, providing users with a variety of choices to adapt to different usage scenarios and power conditions, making it convenient for customers to choose according to their actual needs. It should be noted that different types of telescopic rods are equipped with control devices to control their extension and retraction.

[0033] Furthermore, a servo motor 107 is fixedly installed on the side wall of the mounting shell 101. The output shaft of the servo motor 107 is always parallel to the axis of the spiral feed rod 104. The lower end of the spiral feed rod 104 is rotatably inserted through the interior of the mounting shell 101 via a sealed bearing. The output shaft of the servo motor 107 is rotatably inserted through the interior of the mounting shell 101 via a sealed bearing. A transmission wheel 108 is fixedly installed on the lower end of the spiral feed rod 104 and the output shaft of the servo motor 107, respectively. The two transmission wheels 108 are linked by a transmission belt 109. The outer side of the transmission wheel 108 and the inner side of the transmission belt 109 are respectively provided with interlocking anti-slip patterns. The servo motor 107 drives the spiral feed rod 104 to rotate through the transmission wheels 108 and the transmission belt 109. The interlocking anti-slip patterns on the transmission wheels 108 and the transmission belt 109 help to enhance the stability of the transmission, reduce slippage, and ensure the continuity of feeding.

[0034] Furthermore, the upper half of the feeding hopper 200 is cylindrical and the lower half is conical. The inner wall surface of the feeding hopper 200 is smooth, which is conducive to the feed gathering into the feed pipe 105 under its own gravity and reducing the residue of feed on the inner wall of the feeding hopper 200.

[0035] Furthermore, the multi-layered first stirring blades 203 are located in the lower half of the inner cavity of the feeding hopper 200. The length of each layer of the first stirring blades 203 gradually decreases along the tapering direction of the conical surface of the feeding hopper 200, and the distance between the end of each first stirring blade 203 and the inner wall of the feeding hopper 200 is no more than one centimeter. The multi-layered first stirring blades 203 can better adapt to the conical structure of the lower half of the feeding hopper 200, which helps to stir the feed near the inner wall and reduce feed accumulation.

[0036] Furthermore, the multi-layered second stirring blades 205 are located in the upper half of the inner cavity of the feeding hopper 200. The length of each layer of the second stirring blades 205 gradually decreases from the outer side of the fixed shell 201 toward the inner side of the feeding hopper 200, and the distance between the end of each second stirring blade 205 and the inner wall of the feeding hopper 200 is no more than one centimeter. By setting up the multi-layered second stirring blades 205, it can be adapted to the cylindrical structure of the upper half of the feeding hopper 200, which is conducive to fully stirring the feed in the upper part and improving the stirring effect.

[0037] Furthermore, a servo motor 208 is fixedly installed at the top center of the hopper 200. The output shaft of the servo motor 208 rotates through the top wall of the hopper 200 via a sealed bearing and is fixedly connected to the top end of the first stirring rod 202. The servo motor 208 can provide stable power to the first stirring rod 202, ensuring that the first stirring blade 203 and the second stirring blade 205, which are driven by gears, work continuously and ensuring the stable progress of the stirring process.

[0038] Furthermore, the top of the feeding hopper 200 is fixedly provided with a feeding pipe 209 that communicates with its own inner cavity. The upper end of the feeding pipe 209 is provided with a sealing plug 210. The feeding pipe 209 facilitates the addition of feed into the feeding hopper 200. The sealing plug 210 can seal the feeding pipe 209 when no feed is added, which helps to reduce the entry of external impurities into the feeding hopper 200 and keep the feed clean.

[0039] When using this feed conveying screw feeder, the following procedure can be followed:

[0040] Depending on the target height of the feed conveying, the tilt angle of the feeding pipe 102 can be changed by adjusting the extension length of the telescopic rod 103 to adapt to different conveying height requirements.

[0041] Open the sealing plug 210 on the feed pipe 209, pour the feed to be conveyed into the feed hopper 200 through the feed pipe 209, and then replace the sealing plug 210 to prevent external impurities from entering.

[0042] When the servo motor 208 is started, its output shaft drives the first stirring rod 202 to rotate. The first stirring rod 202 drives the second stirring rod 204 to rotate synchronously through the meshing transmission of the first bevel gear 206 and the second bevel gear 207. At this time, the first stirring blade 203 and the second stirring blade 205 stir the feed in the feeding hopper 200 from different directions, reduce feed agglomeration, and promote the feed to flow into the feed pipe 105.

[0043] The servo motor 107 is started, and its output shaft drives the screw feed rod 104 to rotate inside the feed pipe 102 through the linkage of the transmission wheel 108 and the transmission belt 109. Through the rotation of the screw feed rod 104, the feed that enters the feed pipe 102 from the feed pipe 105 is pushed along the feed pipe 102 to the higher end and discharged from the discharge pipe 106, thus completing the feed delivery.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
