[0019] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0020] like Figures 1 to 4 As shown, a pre-feeding mechanism for a cement kiln pre-combustion furnace includes a frame 1 and two feeding rollers, with the two ends of the frame 1 being the front end and the rear end, respectively. A conveying device is also provided on the frame 1, which can transport solid waste materials from the front end to the rear end of the frame 1.

[0021] The conveying device includes a conveyor belt 7 and a power roller assembly. The power roller assembly includes a driving roller 8 and several driven rollers 9, which are evenly distributed along the length of the frame 1. In this application, the driving roller 8 is designed to be located near the rear end of the frame 1. Both the driving roller 8 and the driven rollers 9 are rotatably connected to the frame 1. The conveyor belt 7 is fitted onto the power roller assembly and is driven by it. Due to the large mass of the solid waste material, the design of multiple driven rollers 9 can enhance the load-bearing capacity of the conveyor belt 7, thereby preventing the middle of the conveyor belt 7 from sagging and thus making the conveyor belt 7 less prone to damage.

[0022] The two feeding rollers are designated as the first feeding roller 2 and the second feeding roller 3. The first feeding roller 2 is located diagonally above the second feeding roller 3 and is closer to the front end of the frame 1. The two feeding rollers rotate in the same direction, meaning that the downward and rearward movement of the first feeding roller 2 is opposite to the upward and frontal movement of the second feeding roller 3. Since the first feeding roller 2 is located diagonally above the second feeding roller 3, the solid waste material entering between the first feeding roller 2 and the second feeding roller 3 is subjected to forces in two directions, thus more thoroughly breaking up the solid waste material.

[0023] To enable the two feeding rollers to more efficiently disperse solid waste, several rows of feeding protrusions are provided on both rollers, arranged circumferentially around the rollers. Each row of feeding protrusions includes several triangular feeding protrusions 4. The protrusions 4 in the same row are evenly distributed along the length of the roller, with adjacent rows staggered. When dispersing solid waste, the feeding protrusions 4 can insert into the solid waste and, with rotation, disperse the aggregated solid waste.

[0024] The frame 1 is equipped with an adjustment mechanism. The two ends of the second feeding roller 3 are directly rotatably connected to the side wall of the frame 1, and the two ends of the first feeding roller 2 are connected to the adjustment mechanism. The adjustment mechanism can adjust the height of the first feeding roller 2, thereby adjusting the distance between the first feeding roller 2 and the second feeding roller 3. By changing the distance between the first feeding roller 2 and the second feeding roller 3, the degree to which the two feeding rollers disperse the solid waste material can be changed. The smaller the distance between the two feeding rollers, the more thoroughly the solid waste material is dispersed.

[0025] The adjustment mechanism includes two sliders and two adjusting screws 5. Symmetrical slides are provided on the side walls of both sides of the frame 1. The two sliders are located within their respective slides and are slidably connected to them. The slides penetrate the side walls of the transverse frame 1. The thickness of the sliders is greater than the side walls of the frame 1, so that a portion of the sliders is located outside the slides. A fixing block 6 is also provided on the frame 1, and is fixedly connected to the frame 1. The fixing block 6 has a threaded hole, through which one end of the adjusting screw 5 passes and is threadedly engaged. The lower end of the adjusting screw 5 is engaged with the upper surface of the slider and is rotatably connected to the upper surface of the slider, allowing the adjusting screw 5 to hold the slider in place and prevent it from falling, without the slider affecting the rotation of the adjusting screw 5. The connection structure between the adjusting screw 5 and the slider is a common structure, such as inserting a bearing into the top of the slider and fixing the adjusting screw 5 to the inner edge of the bearing. The adjusting screw 5 can adjust the height of the sliders, and the height between the two sliders can be adjusted independently. The two ends of the first feeding roller 2 are respectively inserted into the two sliders and are rotatably connected to them.

[0026] A power mechanism is also provided on one side of the frame 1. The power mechanism includes a motor 10, three driving gears, three driven gears, and three transmission chains. The three driving gears are driving gear one 11, driving gear two 12, and driving gear three 13, and the three driven gears are driven gear one 14, driven gear two 15, and driven gear three 16.

[0027] Drive gear 11 is fixed to the output shaft of motor 10. Drive gear 2 12 and driven gear 1 14 are fixed to one end of drive roller 8. Drive gear 3 13 and driven gear 2 15 are fixed to one end of second feeding roller 3. Drive gear 3 16 is fixed to one end of first feeding roller 2. A transmission chain is fitted on drive gear 11 and driven gear 14, drive gear 2 12 and driven gear 2 15, and drive gear 3 13 and driven gear 3 16.

[0028] Motor 10 drives drive gear 11 to rotate, which in turn drives driven gear 14 to rotate via a transmission chain. Driven gear 14 then drives the power roller to rotate, enabling the power roller to drive the conveyor belt 7. Drive gear 12 follows the power roller and drives driven gear 15 to rotate via a transmission chain, which in turn drives the second feeding roller 3 to rotate. Drive gear 13 follows the second feeding roller 3 and drives driven gear 16 to rotate via a transmission chain, which in turn drives the first feeding roller 2 to rotate. Thus, after motor 10 starts, the conveyor and the two feeding rollers can start simultaneously.

[0029] In this design, all gears are of the same size, meaning that the two feeding rollers rotate at the same speed. However, gears of different sizes can be selected according to actual needs to change the speed of the two feeding rollers and the conveying device.

[0030] A guide groove is also provided on the frame 1, and a guide block is provided in the guide groove. The guide block is slidably connected to the guide groove, and an adjusting spring 17 is provided in the guide groove. The adjusting spring 17 pulls the guide block and generates a pulling force on the guide block. An adjusting gear 18 is rotatably connected to the guide block. The adjusting gear 18 is located in the transmission chain sleeved on the driving gear 3 13 and the driven gear 3 16. When the distance between the two feeding rollers is changed, the adjusting gear 18 will generate a pulling force on the transmission chain under the action of the spring force, so that the transmission chain is kept in a relatively taut state, thereby allowing the transmission chain to drive the driven gear 3 16 to rotate.

[0031] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
