When the second motor 11 is working, it will drive the reciprocating screw rod 12 to rotate, and then drive the scraper ring 14 to move. After the scraper ring 14 moves, it can scrape off the material attached to the inner wall of the feeding barrel 3 to prevent some material from adhering to the inner wall of the feeding barrel 3. A blowing component 9 is provided inside the scraper ring 14, and two vertical plates 2 are fixed on one side of the top of the base plate 1, and the feeding barrel 3 is connected between the two vertical plates 2 by a rotating shaft 15. The feeding barrel 3 is rotatably connected to the vertical plate 2 through the rotating shaft 15, and the vertical plate 2 can support the feeding barrel 3. At the same time, the setting of the rotating shaft 15 facilitates the rotation of the feeding barrel 3.

[0040] See also Figure 1-Figure 3 A motor box 4 is installed on one side of the feed barrel 3, and a drive motor 5 is installed inside the motor box 4. A heat dissipation port is opened on one side of the top of the motor box 4. When the material needs to be transported, the staff can start the drive motor 5 to make the drive motor 5 work and drive the conveying shaft 6 to rotate. The output end of the drive motor 5 is connected to the conveying shaft 6 extending to the inside of the feed barrel 3, and the outer wall of the conveying shaft 6 is provided with a spiral blade 7. The conveying shaft 6 drives the spiral blade 7 to rotate, and the spiral blade 7 can transport the material. A feed hopper 10 is installed on the other side of the top of the feed barrel 3, and a discharge pipe 13 is connected to one side of the bottom of the feed barrel 3. The material can enter the inside of the feed barrel 3 through the feed hopper 10, and the material can be discharged through the discharge pipe 13.

[0041] Specifically, the blowing assembly 9 includes an air guide channel 905 and a plurality of jet holes 906 opened above the interior of the scraper ring 14, a connecting shaft 901 installed at one end of the reciprocating screw 12, and an air intake box 908 installed on one side of the top of the feed barrel 3, and the interior of the air intake box 908 is respectively provided with a rotating shaft 909 and a movable shaft 913 through bearings, and the outer wall of the rotating shaft 909 is installed with a driven gear 911 and a fan blade 910, and the jet hole 906 is connected with the air guide channel 905 so that air can enter the interior of the jet hole 906 through the air guide channel 905.

When the connecting shaft 901 rotates, it will drive the sprocket 902 connected thereto to rotate, and at the same time, the chain 903 drives another sprocket 902 to rotate, and then drives the movable shaft 913 to rotate. A gas hose 904 extending to the inside of the air guide channel 905 is connected to the lower side of the air intake box 908, and a one-way valve air nozzle 907 is installed inside the air injection hole 906.

[0043] Specifically, the driving gear 914 is meshed with the driven gear 911, and the diameter of the driving gear 914 is larger than the diameter of the driven gear 911. The fan blade 910 is located on one side of the air inlet 912. When the driving gear 914 rotates, it will drive the driven gear 911 to rotate.

At the same time, the setting of the dustproof net facilitates filtering the incoming air to prevent impurities from entering the interior of the air inlet box 908.

[0044] Embodiment 2:

[0045] On the basis of the above-mentioned first embodiment, in order to facilitate the discharge of materials, it is necessary to adjust the inclination angle of the discharge pipe 13, so the following structure is set.

[0046] See also Figure 1-Figure 3 An adjustment component 8 is provided on the other side of the top of the base plate 1, and the adjustment component 8 includes a first motor 802 and a fixed frame 801 installed on the other side of the top of the base plate 1. The output end of the first motor 802 is connected to a screw rod 803. When the angle of the feed barrel 3 needs to be adjusted, the staff can start the first motor 802, and the first motor 802 can drive the screw rod 803 to rotate. The outer wall of the screw rod 803 is sleeved with a movable seat 804, and the outer surface and back of the movable seat 804 are rotatably connected to the bottom of the feed barrel 3 through a support plate 805. When the screw rod 803 rotates, it will drive the movable seat 804 to move. When the movable seat 804 moves, it will drive the support plate 805 to rotate. The movable seat 804 is threadedly connected to the screw rod 803, and the outer wall of the movable seat 804 fits the inner wall of the fixed frame 801.

[0047] The working principle of the utility model is as follows: first, the staff can move the screw conveyor to the specified position and turn on the power supply, and then adjust the angle of the discharge pipe 13 according to the material discharge height. The adjustment process is to start the first motor 802, and the first motor 802 drives the screw rod 803 to rotate. When the screw rod 803 rotates, it drives the movable seat 804 to move. When the movable seat 804 moves, it drives the support plate 805 to rotate. The support plate 805 can push the feed tube 3 to rotate. After the feed tube 3 rotates, it can drive the discharge pipe 13 to rotate, so that the angle of the discharge pipe 13 can be adjusted to facilitate the subsequent material discharge.

[0048] Then, the material is added into the feed hopper 10, and the drive motor 5 is started. The drive motor 5 can drive the conveying shaft 6 to rotate, and the conveying shaft 6 drives the spiral blade 7 to rotate. The spiral blade 7 can convey the material, and the material can fall into the discharge pipe 13 and be discharged through the discharge pipe 13;

[0049] When it is necessary to clean the inside of the feeding barrel 3, the staff can start the second motor 11. The operation of the second motor 11 can drive the reciprocating screw 12 to rotate, and the reciprocating screw 12 drives the scraper ring 14 to move. The scraper ring 14 can scrape the material attached to the inner wall of the feeding barrel 3. At the same time, the reciprocating screw 12 will drive the connecting shaft 901 to rotate. When the connecting shaft 901 rotates, it will drive the sprocket 902 connected thereto to rotate. At the same time, the chain 903 drives another sprocket 902 to rotate, and then drives the movable shaft 913 to rotate, and then drives the driving gear 914 to rotate, and then drives the driven gear 911 to rotate, and drives the rotating shaft 909 to rotate. Since the diameter of the driven gear 911 is smaller than the diameter of the driving gear 914, the rotation speed of the rotating shaft 909 can be accelerated, and the rotating shaft 909 The rotation will drive the fan blades 910 to rotate. After the fan blades 910 rotate, the circulation speed of the surrounding air will be accelerated, and the external air will enter the air intake box 908 through the air inlet 912. The air will then enter the air guide channel 905 through the air supply hose 904, and will be sprayed out through the air jet hole 906 and the one-way valve air nozzle 907, so as to blow the materials attached to the conveying shaft 6 and the spiral blade 7. At the same time, the driving motor 5 drives the conveying shaft 6 to rotate. Since the reciprocating screw 12 continues to rotate and drives the scraper ring 14 to move continuously, the external air will continue to enter the air intake box 908 and continue to be sprayed out through the air jet hole 906, so that the materials attached to the conveying shaft 6 and the spiral blade 7 can fall off, thereby achieving the purpose of cleaning the inside of the conveying barrel 3.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
