[0002] In material handling operations in the fields of mining, tunnel excavation and underground engineering, the scraper is an efficient and dedicated excavation and loading equipment that integrates excavation, conveying and loading functions. It can achieve continuous and efficient removal and transportation of slag, rock or other bulk materials in a small and complex working environment.

[0003] Existing scraper type scrapers are usually equipped with a feed shovel, which is used to initially collect and guide materials into the subsequent scraper conveyor belt for transmission. However, the feed shovel is often installed in an inclined and fixed manner. When the excavation mechanism of the scraper pushes the material to the feed shovel, it usually cannot push the material completely into the scraper conveyor belt. Some materials are scattered on both sides of the feed shovel or slide along it to the ground. The low feeding efficiency seriously restricts the actual transportation efficiency of the material.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] Example 1

[0018] Reference Figure 1 The utility model provides a scraper for convenient feeding, including a traveling mechanism 1, a steering chassis 2 installed on the traveling mechanism 1, used to control the overall steering of the scraper, to ensure that the equipment can be accurately positioned in a narrow space or complex terrain, an excavation mechanism 4 is fixed on the steering chassis 2, in actual application, the excavation mechanism 4 includes but is not limited to hydraulic arms, buckets and other components, used to excavate materials and send the materials to the scraper conveying mechanism 3, the scraper conveying mechanism 3 is installed on the steering chassis 2 below the excavation mechanism 4, and a feeding shovel 5 is installed at the lower end of the scraper conveying mechanism 3. When working, the excavation mechanism 4 sends the material into the scraper conveying mechanism 3 along the feeding shovel 5, and the scraper conveying mechanism 3 continuously transports the material to the transfer vehicle below its discharge end.

[0019] Reference Figure 2 The feed shovel 5 is installed at the lower end of the scraper conveyor mechanism 3 and is connected to the scraper conveyor mechanism 3 by a hinged manner; baffle plates 501 are arranged on both sides of the feed shovel 5 to prevent the material from overflowing from the side, one end of the baffle plate 501 extends to the side of the scraper conveyor mechanism 3, and a rotating drive column 502 is installed at its end, and a connecting rod 6 is installed on the side of the scraper conveyor mechanism 3. The middle part of the connecting rod 6 is rotatably connected to the scraper conveyor mechanism 3, and strip sliding holes 601 are opened at both ends.

[0020] A cylinder 9 is provided at the bottom of the scraper conveying mechanism 3, and guide plates 7 are installed on the scraper conveying mechanism 3 on both sides of the cylinder 9. The guide plates 7 are provided with guide bar holes 701, and push rods 8 are installed in the guide bar holes 701. The middle part of the push rod 8 is connected to the piston rod of the cylinder 9, and the two ends of the push rod 8 and the rotating driving column 502 are respectively installed in two strip-shaped sliding holes 601;

[0021] The cylinder 9 is usually double-acting and powered by a hydraulic system or compressed air. When the cylinder 9 is actuated, the push rod 8 slides in the guide bar hole 701 and drives the feed shovel 5 to swing through the connecting rod 6. When the excavating mechanism 4 feeds materials into the feed shovel 5, the angle between the feed shovel 5 and the scraper conveying mechanism 3 is the largest, and its lower end contacts the ground to facilitate the feeding of the excavating mechanism 4. After the feeding is completed, the feed shovel 5 flips upward driven by the cylinder 9 and the connecting rod 6, so that its lower end gradually becomes higher than the hinge with the scraper conveying mechanism 3. When the excavating mechanism 4 feeds materials, the residual materials in the feed shovel 5 slide into the scraper conveying mechanism 3 under the action of gravity, thereby improving the feeding efficiency of the excavating mechanism 4.

[0022] Embodiment 2,

[0023] In actual application, the extension speed of the cylinder 9 is slow, and the feeding efficiency of the excavating mechanism 4 is restricted by the cylinder 9. Therefore, based on Example 1, Figure 3 : Slide rails 10 are installed on both sides of the scraper conveying mechanism 3, and a tooth plate 11 is installed on the slider of the slide rail 10. A strip slide hole 601 is opened at one end of the connecting rod 6, and the rotation drive column 502 is installed in the strip slide hole 601. A fan gear 602 is installed at the other end. The fan gear 602 is set with the connection between the connecting rod 6 and the scraper conveying mechanism 3 as the center of the circle. The tooth plate 11 is engaged with the fan gear 602. When the tooth plate 11 moves, it drives the connecting rod 6 to swing.

[0024] Two sets of shaft seats 12 are installed at the bottom of the scraper conveying mechanism 3. Two parallel rotating shafts 13 are installed on the shaft seats 12. A half gear 14 matching the tooth plate 11 is installed at one end of the rotating shaft 13, and a driven gear 15 is installed at the other end. The two driven gears 15 are meshed with each other. A motor 17 and a drive shaft 16 are installed between the two sets of shaft seats 12. The output shaft of the motor 17 is connected to the drive shaft 16. The driven gears 15 on the two sets of shaft seats 12 are meshed with one end of the adjacent drive shaft 16. When the motor 17 is working, it will drive the drive shaft 16 to rotate, and then drive the driven gear 15 and the rotating shaft 13 to rotate, so that the half gear 14 drives the tooth plate 11 to reciprocate, so that the feed shovel 5 continuously feeds the materials produced and retained thereon into the scraper conveying mechanism 3. Compared with the cylinder 9 drive, the frequency of the feed shovel 5 flipping can be adjusted by the speed of the motor 17, and the corresponding speed is fast, which is more suitable for the high-frequency operation of the excavation mechanism 4.

[0025] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
