Description

Technical Field

[0001] The utility model relates to the technical field of feed transportation, in particular to a scraper type feed conveyor. Background Art

[0002] Scraper conveyor, also known as chain scraper conveyor, is often used for horizontal or inclined transportation of powdery and granular materials. It is widely used in building materials, construction, chemical industry, thermal power, food and other mining, machinery, smelting, transportation, port transportation and other industries.

[0003] At present, in the process of using scraper conveyors to transport feed, scraper conveyors are used in combination with flat plates. Multiple scrapers on the scraper conveyors will slide on the flat plates. After the feed is injected into the scraper conveyor, the scrapers will push the feed on the flat plates to move when they rotate. This causes the bottom of the scrapers inside the scraper conveyors to be severely worn and have a short lifespan after long-term use. Therefore, we propose a scraper feed conveyor to solve the above problems. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the above-mentioned background technology and proposes a scraper-type feed conveyor.

The longitudinal support frame is rotatably connected to a first transmission shaft, the two first transmission shafts are connected through a double-chain scraper chain transmission, and the two transverse support frames are rotatably connected to multiple second transmission shafts, and the multiple second transmission shafts are located between the two first transmission shafts. A meshing cylinder is fixedly sleeved on the outer wall of the second transmission shaft, and the two outermost meshing cylinders are connected through a toothed synchronous belt transmission. The multiple scrapers on the double-chain scraper chain are slidably connected to the outer wall of the toothed synchronous belt, and the two chains on the double-chain scraper chain are slidably connected to the side wall of the toothed synchronous belt, a servo motor is fixedly connected to the outer wall of one of the longitudinal support frames, and the adjacent servo motor output shaft is fixedly connected to the end of the first transmission shaft, and multiple support plates are fixedly connected to the top of the fixed platform, and a horizontal patch plate is fixedly connected between two adjacent support plates, and the horizontal patch plate is located between the first transmission shaft and the toothed synchronous belt.

[0007] Preferably, the distances between two adjacent second transmission shafts are the same.

[0008] Preferably, a synchronous chain disc adapted to the toothed synchronous belt is fixedly sleeved on the outer side wall of the first transmission shaft.

[0009] Preferably, the top of the horizontal patch plate is flush with the top of the toothed synchronous belt.

[0010] Preferably, a mounting plate is fixedly connected to the outer side wall of one of the longitudinal support frames, and the bottom of the servo motor and the top of the mounting plate are fixedly connected.

[0011] Preferably, the outer side walls of the two first transmission shafts are sleeved with double-chain chain plates adapted to the double-chain scraper chains.

[0012] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3A scraper feed conveyor comprises a fixed platform 1 and two groups of longitudinal support frames 2 and two transverse support frames 3 fixedly arranged on the top of the fixed platform 1. A first transmission shaft 4 is rotatably connected to the longitudinal support frame 2. The two first transmission shafts 4 are connected by a double-chain scraper chain 5. A plurality of second transmission shafts 6 are rotatably connected between the two transverse support frames 3. The distance between two adjacent second transmission shafts 6 is the same. Double-chain chain plates matching the double-chain scraper chains 5 are sleeved on the outer side walls of the two first transmission shafts 4. The double-chain scraper chains 5 are commonly used in the prior art and will not be described in detail here.

[0020] A plurality of second transmission shafts 6 are located between the two first transmission shafts 4, and a meshing cylinder 7 is fixedly sleeved on the outer side wall of the second transmission shaft 6. The two outermost meshing cylinders 7 are connected by a toothed synchronous belt 8. A synchronous chain disk adapted to the toothed synchronous belt 8 is fixedly sleeved on the outer side wall of the first transmission shaft 4;

[0021] The multiple scrapers on the double-chain scraper chain 5 are all slidably connected to the outer wall of the toothed synchronous belt 8, and the two chains on the double-chain scraper chain 5 are all slidably connected to the side wall of the toothed synchronous belt 8. A servo motor 10 is fixedly connected to the outer wall of one of the longitudinal support frames 2, and a mounting plate 9 is fixedly connected to the outer wall of one of the longitudinal support frames 2. The bottom of the servo motor 10 is fixedly connected to the top of the mounting plate 9;

[0022] The output shafts of adjacent servo motors 10 are fixedly connected to the ends of the first transmission shaft 4, a plurality of support plates 11 are fixedly connected to the top of the fixed platform 1, a horizontal patch plate 12 is fixedly connected between two adjacent support plates 11, the horizontal patch plate 12 is located between the first transmission shaft 4 and the toothed synchronous belt 8, and the top of the horizontal patch plate 12 is flush with the top of the toothed synchronous belt 8.

[0023] The functional principle of the utility model can be explained through the following operation mode: start the output shaft of the servo motor 10 to rotate forward, the output shaft of the servo motor 10 drives the first transmission shaft 4 to rotate, and the two first transmission shafts 4 are transmitted through the double-chain scraper chain 5, so that multiple scrapers on the double-chain scraper chain 5 will slide on the toothed synchronous belt 8. If the double-chain scraper chain 5 is to move in the reverse direction, it is only necessary to start the output shaft of the servo motor 10 to reverse;

[0024] When using the device to transport feed, first start the output shaft of the servo motor 10, and let the workers pour the feed to be transported onto the toothed synchronous belt 8. The multiple scrapers on the rotating double-chain scraper chain 5 can push the feed. At the same time, due to the increase in friction between the feed and the toothed synchronous belt 8, as the double-chain scraper chain 5 rotates, the feed will push the toothed synchronous belt 8 to rotate, thereby allowing the double-chain scraper chain 5 to transport the feed. At the same time, the horizontal filler plate 12 can make up for the gap between the toothed synchronous belt 8 and the double-chain chain disc, making it easier for the feed to be unloaded through the horizontal filler plate 12.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
