DETAILED DESCRIPTION ​

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, this utility model provides an adjustable scraper conveyor, including a support frame 1, a conveyor chain 2, and a servo motor 3. Several feeding scrapers 4 are equidistantly fixed on the outer surface of the conveyor chain 2. Support side plates 5 are provided at both ends of the conveyor chain 2. The end of each support side plate 5 closest to the servo motor 3 is rotatably sleeved onto the support frame 1. Support columns 6 are provided on the outer sides of the two support side plates 5 furthest from the servo motor 3. Connecting screws 7 are rotatably sleeved on the upper and lower ends of each support column 6. The two upper connecting screws 7 are fixed to the sidewall of the support side plate 5, and the two lower connecting screws 7 are fixed to the sidewall of the support side plate 5. All connecting screws 7 are fixed on the support frame 1. The bottom ends of the two support columns 6 and the opposite sides of the support frame 1 are each provided with an L-shaped interlocking mechanism. The bottom end of the support column 6 is provided with a rotating hole that mates with the connecting screw 7, which facilitates the rotation of the support column 6. Each connecting screw 7 is threaded with a fixing nut 8 at one end extending to the outside of the support column 6. The upper part of the support column 6 is provided with an adjustment groove 9 that mates with the upper connecting screw 7, so that the upper connecting screw 7 can rotate inside the support column 6 and slide inside the adjustment groove 9, thereby facilitating its rotation with the support side plate 5.

[0023] The specific settings and functions of this embodiment are described below: Each connecting screw 7 is set as a horizontally placed T-shape to prevent the fixing nut 8 from separating from the connecting screw 7. The upper and lower ends of the adjusting groove 9 are both set as semi-circles to cooperate with the connecting screw 7, so that the connecting screw 7 can slide inside the adjusting groove 9. The width of each fixing nut 8 is greater than the width of the adjusting groove 9, so that the fixing nut 8 can clamp and fix the support column 6.

[0024] like Figures 1-4As shown, a side baffle 10 is symmetrically fixed on the top surface of the support frame 1 away from the support column 6. A drive roller 11 is symmetrically rotatably connected between the two side baffles 10. A feeding belt 12 is driven on the two drive rollers 11. The end of the feeding belt 12 near the servo motor 3 extends above the conveyor chain plate 2. The width of the feeding belt 12 is equal to the width of the conveyor chain plate 2. A pulley 13 is fixed at the output end of the servo motor 3 and at the end of the drive roller 11 near the servo motor 3 that extends to the outside of the side baffle 10. The two pulleys 13 are connected by a transmission belt 14. A material support box 15 is fixed at the bottom end of the support side plate 5 below the feeding belt 12. The material support box 15 is set in an arc shape to cooperate with the support side plate 5 and the feeding scraper 4. Through the fixed design of the material support box 15 and the support side plate 5, when the feeding belt 12 transports the material, after the feeding end of the conveyor chain plate 2, it can fall into the material support box 15, which makes it convenient for the feeding scraper 4 to dig out the material from the inside of the material support box 15 when it moves.

[0025] The usage and working principle of this device are as follows: When it is necessary to adjust the height of the material feeding end of the support side plate 5, tighten the fixing nut 8 to release the clamping fixation of the fixing nut 8 on the support column 6. Rotate the support side plate 5 so that the support side plate 5 rotates on the support frame 1. At the same time, it drives the end of the conveyor chain plate 2 near the support frame 1 to rotate on the chain roller inside. When rotating, it drives the connecting screw 7 to slide inside the support column 6. While sliding, it pushes the bottom of the support column 6 to rotate on the support frame 1. After adjusting the height of the support side plate 5, tighten the fixing nut 8. The fixing nuts 8 at the upper and lower ends clamp and fix the support column 6. When conveying materials, pour the materials onto the feeding belt 12. The servo motor 3 operates. The conveyor belt 14 drives the pulley 13 connected to it to rotate. The pulley 13 drives the pulley 13 on the drive roller 11 to rotate, thereby driving the drive roller 11 to rotate. The rotation of the drive roller 11 drives the feeding belt 12 to move towards the conveyor chain plate 2, and at the same time drives the conveyor chain plate 2 to move towards the support column 6. Then the material is poured onto the feeding belt 12. The feeding belt 12 continuously carries the material into the material box 15. The conveyor chain plate 2 drives the feeding scraper 4 below to move towards the servo motor 3. After moving into the material box 15, the feeding scraper 4 digs out the material inside the material box 15 while rotating upward, and moves to the support column 6 for unloading under the drive of the conveyor chain plate 2.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
