Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically a loading conveyor. Background Technology

[0002] Conveyors are widely used mechanical equipment in industrial and logistics fields, mainly used to transfer goods and materials from one place to another. Currently, the most common type is the belt conveyor, which transports goods through the rotation of conveyor rollers and a conveyor belt. In high-angle belt conveyors that transport goods from low to high, the goods fall directly off the conveyor belt at the end. When loading goods onto trucks, they may accumulate in certain areas within the truck bed. This usually requires manual distribution of the goods or moving the vehicle to adjust the pile position. Manual operation is laborious, and some goods, such as grains, may generate dust that affects workers' breathing. Furthermore, it's difficult for drivers to control the adjustment distance, and ultimately, manual leveling is still necessary. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a loading conveyor with the following advantages:

[0015] 1. This loading conveyor, by setting an additional short conveyor frame 2 at the top front end of the conveyor frame 1, when the items conveyed by the conveyor frame 1 are transferred to the conveyor frame 2, the position of the items falling off the conveyor frame 2 can be adjusted by adjusting the angle of the conveyor frame 2, so that the position of the items falling off the conveyor frame 2 can exhibit linear characteristics within the rotation range of the conveyor frame 2. In this way, when conveying grain, it is not necessary to manually spread out or move the vehicle for adjustment.

[0016] 2. This loading conveyor, through the cooperation of each pulley and belt, enables the transmission between conveyor belt two and conveyor belt one. The rotation of conveyor belt one can drive the rotation of conveyor belt two, without the need for additional power equipment for conveyor belt two.

[0017] 3. This loading conveyor uses the cooperation of tension rollers and springs to adjust the distance as the conveyor frame rotates, thereby ensuring stable and reliable transmission.

[0018] 4. By installing splash guards, this loading conveyor can prevent items from being thrown out of the range of the second conveyor belt and falling off when they are conveyed by the first conveyor belt. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-6 A loading conveyor includes a conveyor frame 1, which is inclined at 30°. A bottom roller 2 is mounted on the bottom end of the inclined conveyor frame 1 through a bearing assembly, and a top roller 3 is mounted on the top end of the inclined conveyor frame 1 through a bearing assembly. A conveyor belt 6 is wound around the bottom roller 2 and the top roller 3. Multiple guide rollers 5 with equal spacing are mounted on the conveyor frame 1 between the bottom roller 2 and the top roller 3 through a bearing seat 4. The conveyor belt 6 slides and is supported on the guide rollers 5.

[0028] A second conveyor frame 10 is provided at the top of the first conveyor frame 1. The second conveyor frame 10 is set horizontally and its length is less than that of the first conveyor frame 1, generally 1-3 meters. A rear roller 11 is installed at the rear end of the second conveyor frame 10 facing the first conveyor frame 1 via a bearing set. A front roller 12 is installed at the front end of the second conveyor frame 10 away from the first conveyor frame 1 via a bearing set. A second conveyor belt 13 is wound around the rear roller 11 and the front roller 12. Multiple guide rollers 5 are also installed on the second conveyor frame 10 of the rear roller 11 and the front roller 12 via a bearing seat 4. The second conveyor belt 13 slides and is supported on the guide rollers 5 of the second conveyor frame 10.

[0029] A fixed shaft 14 is welded and installed at the position of the rear end of the conveyor frame 11 after being offset from the roller 11. Multiple shaft seats 15 are fitted on the fixed shaft 14. The shaft seats 15 are bolted to the bottom surface of the conveyor frame 11 at the corresponding position. A motor 18 is installed on the bottom surface of the conveyor frame 11 at the corresponding position. A gear 17 is installed on the shaft of the motor 18. A gear ring 16 is installed on the fixed shaft 14 at the position corresponding to the gear 17. The gear ring 16 meshes with the gear 17 for transmission.

[0030] Pulley 22 is installed at both ends of the top roller 3 outside the conveyor frame 1, and pulley 20 is installed at both ends of the rear roller 11 outside the conveyor frame 20. Pulley 21 is also installed on the outer side of the conveyor frame 1 near pulley 22. A drive belt 29 is wound around pulley 20, pulley 21 and pulley 22. Tension roller 19 is sleeved on pulley 21. Both ends of tension roller 19 are sleeved on the bearings of bushing seat 23 at the corresponding positions to form a sleeved fixation. A fixing plate 24 is welded and installed on the outer wall of the conveyor frame 1 near pulley 20. A spring 25 is provided between bushing seat 23 and fixing plate 24. A sleeve 26 is welded and installed on the fixing plate 24 inside the spring 25. A sleeve rod 27 is welded and installed on the bushing seat 23 inside the spring 25. Part of the sleeve rod 27 extends into the sleeve 26 to form a telescopic sleeve support. A support plate 28 is also welded and installed on the outer wall of the conveyor frame 1 below pulley 21.

[0031] The bottom surface of the conveyor frame 1 is welded with a support frame 8 for ground support. The four corners of the bottom of the support frame 8 are equipped with casters 9. The support frame 8 is equipped with a motor 7 at one end corresponding to the bottom roller 2. The motor 7 and the bottom roller 2 at the corresponding position are connected by a key-pin connection. The top two sides of the conveyor frame 1 are bolted with forward-extending splash guards 30.

[0032] During operation, the conveyor frame 1 can be moved to the desired position using the movable wheels 9. The conveyor frame 2 10 extends above the carriage. During loading, the motor 1 7 is turned on. The items are first placed on the conveyor belt 6 at the bottom of the conveyor frame 1. The motor 1 7 drives the conveyor belt 6 to rotate, thus conveying the items to a higher position. Then, the items fall onto the conveyor belt 2 13 of the conveyor frame 2. At this time, the conveyor belt 2 13 is driven by the top roller 3 through the transmission relationship of the belt 29, conveying the items forward. Finally, the items fall off the conveyor belt 2 13, completing the conveying process.

[0033] During the conveying process, the motor 18 can be intermittently controlled to drive the entire conveyor frame 10 to rotate along the fixed shaft 14 by using the meshing relationship between the gear 17 and the gear ring 16. This adjusts the forward extension angle from the initial horizontal state to the front end tilting state, which shortens the conveying distance of the conveyor belt 10. By continuously adjusting, the distance from which items fall off the conveyor belt 10 can be made linear, without the need for manual spreading or moving of the vehicle for adjustment.

[0034] When motor 218 drives conveyor frame 210 to rotate, the distance between pulley 32 and pulley 120 increases. At this time, belt 29 is compressed and spring 25 contracts, causing pulley 21 to move closer to pulley 32. When conveyor frame 210 returns to horizontal, belt 29 relaxes, spring 25 recovers its deformation and elongates, and pushes pulley 21 away from pulley 32 to adjust the distance, so that belt 29 always maintains a reliable tension.
