[0002] A screw automatic air conveyor is a device that uses the rotation of a screw to convey materials in a semi-circular trough concentric with it. It is a machine for pushing materials to achieve the purpose of conveying. The screw blades are welded on the screw shaft of the screw automatic air conveyor. The surface type of the blades has various forms such as solid surface type, belt type, blade surface type, etc. according to the different conveyed materials. When the screw shaft rotates, due to the gravity of the materials and the friction generated between them and the trough wall, the materials can only move forward along the bottom of the trough under the push of the blades, thus achieving the effect of feeding and conveying.

[0003] In the existing screw automatic air conveyor, power is provided by a motor to drive the screw propulsion shaft composed of a guide plate and a drive shaft, which can convey materials horizontally in a U-shaped or semi-circular enclosed space.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 3 , an anti-adhesion spiral automatic air feeder, including a material conveying shell 1, one end of the outer wall of the material conveying shell 1 is embedded with a conveying motor 2, the power output end of the conveying motor 2 is connected with a screw propelling shaft 3, and a driving mechanism 4 is arranged on one side of the material conveying shell 1; the driving mechanism 4 includes an installation shell 401, the installation shell 401 is fixed at the front end of the material conveying shell 1, one side of the outer wall of the installation shell 401 is embedded with a driving motor 402, the power output end of the driving motor 402 is connected with a worm 403, one end of the worm 403 passing through the installation shell 401 is connected with a worm gear 404 on the outer wall, the inner wall of the worm gear 404 penetrates out with an air spraying pipe 405, the outer wall of one end of the air spraying pipe 405 penetrating into the material conveying shell 1 is provided with an air outlet hole 406, a baffle 407 is fixed inside the material conveying shell 1 corresponding to the position of the air spraying pipe 405, the structure of the baffle 407 is an L-shaped structure, the baffle 407 is in close fit with the air spraying pipe 405, one side of the top end of the material conveying shell 1 is embedded with a feeding hopper 5, and one side of the bottom end of the material conveying shell 1 is provided with a discharge opening 6.

[0028] By adopting the above technical solution, first, the material is introduced into the material conveying shell 1 through the feeding hopper 5. Subsequently, the conveying motor 2 drives the spiral propelling shaft 3 to convey the material inside the U-shaped material conveying shell 1, and the material passes through the discharging port 6, so that the material moves horizontally. When the material moves, the driving motor 402 installed in the installation shell 401 works, driving the worm 403, so that a plurality of worm wheels 404 drive the corresponding air jet pipes 405 to rotate. The gas is ejected through the air outlet holes 406, causing the material adsorbed on the corresponding range of the spiral propelling shaft 3 to fall and be blown. At the same time, the feeding speed can be increased, and the air jet pipes 405 are conveyed along with the conveying of the material. At the same time, when rotating in the direction opposite to the material conveying direction, the baffle 407 blocks to avoid mutual conflict and prevent the material from being scattered and affecting the conveying.

[0029] Specifically, as Figure 1 , Figure 4 and Figure 5 shown, on one side of the feeding hopper 5 at the top of the material conveying shell 1, an installation groove 7 is opened. A sliding plate 8 is slidably connected inside the installation groove 7. A bearing mechanism 9 is arranged at the rear end of the material conveying shell 1. The bearing mechanism 9 includes a support frame 901, the support frame 901 is fixed at the rear end of the material conveying shell 1, a fixed sleeve 902 is embedded inside the support frame 901, the bearing mechanism 9 further includes a conveying pipe 903, the conveying pipe 903 is connected to one end of the fixed sleeve 902, and the other end of the fixed sleeve 902 is rotatably connected to a limiting ring 904. The fixed sleeves 902 are evenly distributed at equal intervals on the outer wall of the support frame 901, and the structure of the support frame 901 is a U-shaped structure.

[0030] By adopting the above technical solution, the sliding plate 8 slides through the installation groove 7, so as to facilitate opening and closing the material conveying shell 1 for maintenance. The limiting ring 904 to which the air jet pipe 405 is fixed penetrates into the fixed sleeve 902, and under the support of the support frame 901, the air jet pipe 405 rotates stably and can maintain communication. The gas is conveyed through the air pump and the conveying pipe 903, and the gas can blow the material adsorbed by the spiral propelling shaft 3 to avoid difficult cleaning due to adsorption.

[0031] Working principle: The sliding plate 8 slides to close the installation groove 7 to keep the material conveying shell 1 airtight. After the material is introduced through the feeding hopper 5, the material is conveyed by the cooperation of the conveying motor 2 and the spiral propelling shaft 3 and discharged through the discharging port 6. Through an external air pump, the gas is conveyed through the conveying pipe 903 to the fixed sleeve 902 and enters the air jet pipe 405. The driving motor 402 fixed to the installation shell 401 drives the worm 403 to push the worm wheel 404, so that the air jet pipe 405 rotates along the material conveying direction. With the cooperation of the support frame 901 and the limiting ring 904, the air jet pipe 405 rotates stably, and the gas is ejected through the air outlet holes 406, blowing the material adsorbed by the spiral propelling shaft 3 to move towards the discharging port 6 to prevent adhesion. When rotating in the reverse direction, it is blocked by the baffle 407 to avoid the gas being too scattered and affecting the conveying of the material.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
