Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a garbage collection device that can be conveyed by a screw conveyor. Background Technology

[0002] For more viscous waste, shaftless screw conveyors are generally used for waste transportation. Compared with traditional shafted screw conveyors, shaftless screw conveyors have the advantage of strong anti-entanglement due to their design without a central shaft and the use of a flexible integral steel screw to push materials.

[0003] Existing shaftless screw conveyors with single helical blades have difficulty crushing waste due to their single helical blade configuration. This makes viscous waste prone to clumping, resulting in heavier clumped waste that slows down the screw conveyor process and reduces transportation efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background section, the present invention provides a garbage collection device with screw conveyor.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A spiral conveying garbage collection device includes a conveying cylinder with rotating holes at both ends. Rotating cylinders are rotatably installed inside each of the two rotating holes. An outer spiral blade is disposed inside the conveying cylinder, with its two ends coaxially fixed to the two rotating cylinders. A second servo motor is fixed to the other end of the conveying cylinder, and the output shaft of the second servo motor is coaxially fixed to one of the rotating cylinders. Rotating columns are rotatably installed inside each of the two rotating cylinders. An inner spiral blade is disposed inside the outer spiral blade, with its two ends coaxially fixed to the two rotating columns. A first servo motor is fixed to the other end of the conveying cylinder, and the output shaft of the first servo motor is coaxially fixed to one of the rotating columns. The pitch of the outer spiral blade is smaller than the pitch of the inner spiral blade.

[0007] As a further improvement of this utility model, it also includes a guide hopper, wherein the discharge hopper of the guide hopper is fixed and connected to one end of the transport cylinder, and the transport cylinder is inclined.

[0008] As a further improvement of this utility model, a welding bracket is fixed to the outside of the guide hopper.

[0009] As a further improvement of this utility model, vertically installed columns are fixed at each of the four corners of the welding bracket.

[0010] As a further improvement of this utility model: a discharge port is provided on the outer side of the top of the transport cylinder, and the discharge port is oriented in the same direction.

[0011] As a further embodiment of this utility model: a guide cylinder is fixed to the outside of the transport cylinder, and the discharge port is located inside the guide cylinder.

[0012] As a further improvement of this invention, there is a gap between the inner side of the outer spiral blade and the outer side of the inner spiral blade.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0014] This invention employs an inner and outer spiral blade design. The pitch of the outer spiral blade is smaller than that of the inner spiral blade, resulting in different transport speeds for the waste inside and outside the blades. The waste transport speed on the inner side is faster than that on the outer side. This differential transport method makes it easier for the waste to get caught between the two spiral blades and be crushed. Because the pitch of the inner spiral blade is larger, the transport speed is faster. The crushed waste is quickly transported to the outlet by the inner spiral blade, thereby improving the overall transport efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4In this embodiment of the utility model, a spiral conveying garbage collection device includes a transport cylinder 3. Both ends of the transport cylinder 3 are provided with rotating holes. Rotating cylinders 6 are rotatably installed inside the two rotating holes. An outer spiral blade 7 is provided inside the transport cylinder 3. The two ends of the outer spiral blade 7 are coaxially fixed to the two rotating cylinders 6 respectively. A second servo motor 10 is fixed to the other end of the transport cylinder 3, and the output shaft of the second servo motor 10 is coaxially fixed to one of the rotating cylinders 6. Rotating columns 8 are rotatably installed inside the two rotating cylinders 6. An inner spiral blade 9 is provided on the inner side of the outer spiral blade 7. The two ends of the inner spiral blade 9 are coaxially fixed to the two rotating columns 8 respectively. A first servo motor 5 is fixed to the other end of the transport cylinder 3. The output shaft of the first servo motor 5 is coaxially fixed to one of the rotating columns 8. The pitch of the outer spiral blade 7 is smaller than the pitch of the inner spiral blade 9. There is a gap between the inner side of the outer spiral blade 7 and the outer side of the inner spiral blade 9.

[0022] As can be seen from the above connection relationship, the design of inner and outer spiral blades, with the outer spiral blade 7 having a smaller pitch than the inner spiral blade 9, results in different transport speeds for the waste inside and outside the spiral blades. The waste transport speed on the inner side is faster than that on the outer side. This differential transport method makes it easier for the waste to get caught between the two spiral blades and be crushed. Because the inner spiral blade 9 has a larger pitch, it has a faster transport speed. The crushed waste is quickly transported to the outlet by the inner spiral blade, thereby improving the overall transport efficiency.

[0023] Specifically, it also includes a guide hopper 2, the discharge hopper of the guide hopper 2 is fixed and connected to one end of the conveying cylinder 3, and the conveying cylinder 3 is set at an incline.

[0024] Specifically, a welding bracket 1 is fixed to the outside of the feed hopper 2, and the welding bracket 1 is used to provide a support point.

[0025] Specifically, vertical columns are fixed at the four corners of the welding bracket 1, and the columns support the guide hopper 2 on the ground.

[0026] Specifically, a discharge port 4 for discharging material is provided on the outer side of the top of the conveying cylinder 3, and the discharge port 4 is oriented in the same direction.

[0027] Specifically, a guide cylinder is fixed on the outside of the transport cylinder 3 to serve as a guide, and the discharge port 4 is located inside the guide cylinder.

[0028] To supplement the above: the rotation direction of the outer spiral blade 7 and the inner spiral blade 9 is not limited. If the rotation directions are the same, they will rotate in the same direction. If the rotation directions are opposite, they will rotate in opposite directions. And rotating in opposite directions is better for crushing waste.

[0029] Working principle:

[0030] The first step is to pour the garbage into the feed hopper 2;

[0031] The second step involves starting the first servo motor 5 and the second servo motor 10. Assuming that the outer spiral blade 7 and the inner spiral blade 9 rotate in the same direction, both the outer spiral blade 7 and the inner spiral blade 9 rotate in the same direction. At this time, both the outer spiral blade 7 and the inner spiral blade 9 transport the waste. Since the pitch of the outer spiral blade 7 is smaller than that of the inner spiral blade 9, the transport speed of the waste inside and outside is different. The transport speed of the waste inside is faster than that of the waste outside. This differential transport method makes it easier for the waste to get caught between the two spiral blades and be crushed. Since the pitch of the inner spiral blade 9 is larger, the transport speed is faster. The waste that has been crushed into small volumes is quickly transported to the outlet by the inner spiral blade, thereby improving the overall transport efficiency.

[0032] The third step is to discharge the waste through the discharge port 4.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
