[0002] Cement-stabilized crushed stone base course is a new type of road base material. It is mainly produced by mixing crushed stone and cement, followed by compaction, resulting in a durable, strong, water-resistant, heat-resistant, pressure-resistant, and skid-resistant road base. It is primarily used to reinforce roadbeds, improve road load-bearing capacity, extend road service life, and effectively solve problems such as differential settlement of the road surface. The preparation of cement-stabilized crushed stone base course requires appropriate batching equipment to mix the crushed stone according to a specific gradation to ensure the compactness and stability of the mixture.
[0003] Common batching equipment mainly includes a batching tank. The top of the batching tank is equipped with multiple feeders. Different grades of crushed stone are simultaneously fed into the batching tank through the various feeders. The agitator inside the batching tank mixes the stone. The bottom of the batching tank is equipped with a switch valve. After the switch valve is opened, the stone falls into the conveyor belt through the discharge port of the batching tank. The conveyor belt sends the mixed stone outward. However, if the stone falls too fast at the discharge port, it will cause the stone to accumulate too high on the conveyor belt, which will cause blockage at the discharge port of the batching tank and affect the normal discharge of the batching tank.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a cement-stabilized crushed stone base batching equipment, including a batching box 2 and a conveyor belt 1 located below the batching box 2. A conical cover 10 is provided between the batching box 2 and the conveyor belt 1. A switch valve 11 is provided at the lower end of the conical cover 10. A bellows-type sleeve 9 is provided at the upper end of the conical cover 10. The bellows-type sleeve 9 is fixedly connected to the lower edge of the batching box 2.
[0023] The mixing box 2 is equipped with a stirring rod 4, and the upper end of the mixing box 2 is equipped with a fixing frame 3. The fixing frame 3 is equipped with a drive component for controlling the rotation of the stirring rod 4.
[0024] There is a gap between the fixed frame 3 and the batching box 2. Multiple sets of conveyor belts for conveying crushed stone are installed on the upper edge of the batching box 2. The crushed stone is poured into the batching box 2 through the conveyor belt. The drive component controls the stirring rod 4 to rotate. The stirring rod 4 accelerates the mixing of stone during rotation. The mixed stone is discharged through the conical cover 10.
[0025] After the switch valve 11 is opened, the stone material falls onto the conveyor belt 1 through the lower port of the conical cover 10. The conveyor belt 1 then sends the prepared stone material outward. However, if the stone material falls too quickly at the switch valve 11, it will cause the stone material on the conveyor belt 1 to accumulate too high, and the lower port of the conical cover 10 will become blocked, affecting the discharge of the batching box 2.
[0026] A drive shaft 12 is provided on the side of the mixing tank 2. The upper end of the stirring rod 4 is provided with a transmission mechanism for driving the drive shaft 12 to rotate. The lower end of the drive shaft 12 is provided with a crank-slider mechanism for pushing the conical cover 10 to sway left and right. The conical cover 10 is movably connected to the lower edge of the mixing tank 2 through an accordion-type sleeve 9. When the stirring rod 4 rotates, the stirring rod 4 will drive the drive shaft 12 to rotate through the transmission mechanism. During the rotation of the drive shaft 12, it will push the conical cover 10 through the crank-slider mechanism. The conical cover 10 sways left and right, clearing away the accumulated stones and ensuring that the lower end of the conical cover 10 is unobstructed.
[0027] Regarding driver components:
[0028] The drive assembly includes a motor 5, which is fixedly connected to the upper end of the mounting frame 3. The output end of the motor 5 is fixedly connected to the upper end of the stirring rod 4. The top end of the stirring rod 4 passes through the mounting frame 3 and is rotatably connected to the mounting frame 3. The rotation of the stirring rod 4 is directly controlled by the motor 5.
[0029] It should be further explained that a rotating shaft bracket 8 is provided on the side of the mixing box 2. The rotating shaft bracket 8 is fixedly connected to the mixing box 2, and the drive shaft 12 passes through the rotating shaft bracket 8, and the rotating shaft bracket 8 is rotatably connected to the drive shaft 12. The rotating shaft bracket 8 fixed on the side of the mixing box 2 is used to support the drive shaft 12 and support the rotation of the drive shaft 12.
[0030] For details on the transmission mechanism, please refer to the following description.
[0031] The transmission mechanism includes a first gear 6 and a second gear 7. The first gear 6 is sleeved on the upper end of the stirring rod 4 and is fixedly connected to the stirring rod 4. The second gear 7 is sleeved on the upper end of the transmission shaft 12 and is fixedly connected to the transmission shaft 12. The first gear 6 and the second gear 7 are connected by a synchronous belt. When the motor 5 drives the stirring rod 4 to rotate, the stirring rod 4 will pull the second gear 7 through belt drive. Since the transmission shaft 12 is fixed to the second gear 7, when the second gear 7 rotates, the transmission shaft 12 will also rotate, thus controlling the crank-slider mechanism.
[0032] For details on the specific structure of the crank-slider mechanism, please refer to the following description.
[0033] The crank-slider mechanism includes a turntable 13 and a fixing pin 14. The turntable 13 is fixedly connected to the lower end of the transmission shaft 12. A limiting plate 15 is provided at the lower end of the turntable 13. The limiting plate 15 is rotatably connected to the eccentric part of the lower end face of the turntable 13. The fixing pin 14 is located below the turntable 13. A connecting rod 18 is provided on the side of the fixing pin 14 facing the conical cover 10. The two ends of the connecting rod 18 are fixedly connected to the conical cover 10 and the fixing pin 14, respectively. A limiting groove 16 is opened at the upper end of the fixing pin 14. The limiting plate 15 is slidably disposed in the limiting groove 16. A sliding sleeve structure for guiding the connecting rod 18 is provided at the lower end of the batching box 2.
[0034] The drive shaft 12 drives the turntable 13 to rotate. As the turntable 13 rotates, the limiting plate 15 fixed at the lower end of the turntable 13 will rotate along with it. The limiting plate 15 slides along the limiting groove 16 and pushes the fixing pin 14, realizing the reciprocating swaying of the fixing pin 14. The conical cover 10 is fixed to the fixing pin 14 through the connecting rod 18. When the fixing pin 14 moves, the conical cover 10 will also sway, shaking the stone material inside the conical cover 10.
[0035] More specifically, the sliding sleeve structure includes a fixed sleeve 17, which is sleeved on the outside of the connecting rod 18 and slidably connected to the connecting rod 18. A support plate is fixedly connected to the lower end of the mixing box 2, and the support plate is fixedly connected to the upper end of the fixed sleeve 17. When the connecting rod 18 wobbles left and right under the push of the limiting plate 15, it will slide along the inner sidewall of the fixed sleeve 17. The fixed sleeve 17 guides the connecting rod 18 by cooperating with it.
[0036] In addition, the lower end of the batching box 2 is equipped with multiple support legs, which are fixedly connected to the batching box 2. The lower end of the conveyor belt 1 is rotatably connected to multiple pulley sets. The support legs support the batching box 2 and fix it above the conveyor belt 1.

[0037] How this application works:
[0038] A gap is left between the fixed frame 3 and the batching box 2. Multiple conveyor belts for conveying crushed stone are installed on the upper edge of the batching box 2. The crushed stone is poured into the batching box 2 through the conveyor belts. The drive component controls the rotation of the stirring rod 4. The stirring rod 4 accelerates the mixing of the stone during rotation. The mixed stone is discharged through the conical cover 10. After the switch valve 11 is opened, the stone falls onto the conveyor belt 1 through the lower port of the conical cover 10. The conveyor belt 1 delivers the mixed stone outward. The conical cover 10 is movably connected to the lower edge of the batching box 2 through the accordion-type sleeve 9. When the stirring rod 4 rotates, the stirring rod 4 drives the transmission shaft 12 to rotate through the transmission mechanism. During the rotation of the transmission shaft 12, the conical cover 10 is pushed through the crank-slider mechanism. The conical cover 10 shakes left and right to clear the accumulated stone and ensure that the lower port of the conical cover 10 is unobstructed.
