Key equipment includes stainless steel mixers, storage silos, drying furnaces, and finished product silos. The process flow is as follows: waste slag - grinding - screening - proportioning - mixing - drying - and finally finished product. When mixing different colors of inorganic sand and gravel, the desired proportions must be tailored to the desired color of the final product. Therefore, a proportioning machine is required for automatic proportioning.

[0003] The existing proportioning machine for preparing inorganic sand and gravel has multiple fan-shaped grooves on the outer wall of the feeding roller, and then the inorganic sand and gravel are fed through the mutual cooperation between the feeding roller and the multiple fan-shaped grooves. The inorganic sand and gravel are quantitatively fed by controlling the rotation time of the feeding roller, and then the inorganic sand and gravel are quantitatively proportioned. However, when quantitatively feeding a variety of inorganic sands and gravels, multiple feeding rollers are required to quantitatively feed a variety of inorganic sands and gravels. Since the required amounts of various inorganic sands and gravels are different, the rotation time of the multiple feeding rollers is also different. Therefore, multiple power sources are required to drive the multiple feeding rollers to rotate, which increases the production cost of the proportioning machine and increases the energy consumption of the proportioning machine during operation.

[0026] See also Figures 1 to 6 A proportioning machine for preparing inorganic sand and gravel includes a mixing barrel body 1, the upper end surface of the mixing barrel body 1 is connected to two feeding pipes 2 distributed on the left and right, the upper end surface of the feeding pipe 2 is connected to a discharge shell 3, the interior of the discharge shell 3 is rotatably connected to a discharge roller 4, and both ends of the discharge roller 4 extend to the outside of the discharge shell 3;

[0027] A cavity 5 is formed inside the unloading roller 4, and a plurality of evenly distributed fan-shaped grooves 6 are formed on the outer wall of the unloading roller 4 and are connected to the cavity 5. An adjustment plate 7 is provided inside the fan-shaped groove 6, and a sliding hole 8 is formed on one side wall of the adjustment plate 7. Two symmetrically distributed movable plates 9 are slidably connected to the interior of the sliding hole 8. The opposite sides of the two movable plates 9 extend to the outside of the sliding hole 8 and are slidably connected to the inner wall of the fan-shaped groove 6.

[0028] The rear end faces of the two unloading rollers 4 are fixedly connected to driven wheels 10, and the upper end face of the mixing barrel body 1 is installed with a motor 11. The output end of the motor 11 is fixedly connected to two driving wheels 12 distributed front and back, and belts 13 are respectively connected between the two driving wheels 12 and the two driven wheels 10.

[0029] In this embodiment: when in use, two different inorganic sands and gravels are respectively placed in the two storage troughs 25, and then the motor 11 is started. The motor 11 drives the two driving wheels 12 to rotate, and the two driving wheels 12 cooperate with the two belts 13 to drive the two driven wheels 10 to rotate. The two driven wheels 10 drive the two unloading rollers 4 to rotate. When the two unloading rollers 4 rotate, the inorganic sands and gravels enter the fan-shaped groove 6. The inorganic sands and gravels are quantitatively proportioned through the mutual cooperation between the unloading rollers 4 and the fan-shaped groove 6. Through the mutual cooperation between the two driving wheels 12, the two belts 13 and the two driven wheels 10, the two unloading rollers 4 can be driven to rotate by one motor 11, thereby reducing the production cost of the proportioning machine and reducing the operating energy consumption of the proportioning machine.

[0030] When the mixing amounts of two different inorganic sand and gravel are different, the depth of the multiple sector grooves 6 on the inorganic sand and gravel feeding roller 4 with a smaller mixing amount is adjusted according to the feeding time of the inorganic sand and gravel with a larger mixing amount, so that the amount of inorganic sand and gravel in the sector groove 6 after the adjustment is reduced, thereby slowing down the feeding efficiency of the inorganic sand and gravel with a smaller mixing amount, making the feeding time of the two inorganic sand and gravel with different mixing amounts the same, thereby quantitatively proportioning the two inorganic sand and gravel with different mixing amounts;

[0031] When adjusting the depth of the fan-shaped groove 6, multiple adjustment plates 7 move outward so that the adjustment plates 7 are close to the opening of the fan-shaped groove 6, thereby reducing the depth of the fan-shaped groove 6. When the adjustment plates 7 move, since the movable plate 9 and the fan-shaped groove 6 are slidably connected through the trapezoidal slider and the trapezoidal slide groove, the two movable plates 9 are driven to extend to both sides of the adjustment plate 7 through the mutual cooperation between the trapezoidal slider and the trapezoidal slide groove. Through the mutual cooperation between the two movable plates 9 and the adjustment plate 7, the bottom of the fan-shaped groove 6 is blocked, thereby adjusting the depth of the fan-shaped groove 6.

[0032] As a technical optimization solution of the present invention, the interior of the cavity 5 is rotatably connected to a screw rod 14, the outer wall of the screw rod 14 is threadedly connected to a moving block 15, and the opposite side walls of the multiple adjustment plates 7 are fixedly connected to an inclined plate 16 that is slidably connected to the moving block 15;

[0033] The front end surface of the unloading roller 4 is provided with a twist block 17 , and the rear end surface of the twist block 17 is provided with a first groove 18 . One end of the screw rod 14 extends into the inside of the first groove 18 and is slidably connected to the first groove 18 .

[0034] In this embodiment: the screw rod 14 is driven to rotate by the torsion block 17, and the screw rod 14 drives the moving block 15 to move. When the moving block 15 moves, since the moving plate 9 and the fan-shaped groove 6 are slidably connected by the trapezoidal slider and the trapezoidal slide groove, the mutual cooperation between the trapezoidal slider and the trapezoidal slide groove can prevent the moving block 15 from rotating with the screw rod 14 while driving multiple inclined plates 16 to move outward, and multiple inclined plates 16 drive multiple adjustment plates 7 to move outward.

[0035] As a technical optimization solution of the present utility model, the front end face of the unloading roller 4 is provided with two second grooves 19 distributed on the left and right, the inner side wall of the second groove 19 is provided with a third groove 20, the inner side of the third groove 20 is slidably connected with a top block 21, and a spring 22 is fixedly connected between the third groove 20 and the top block 21. The rear end face of the torsion block 17 is fixedly connected with two clamping blocks 23 matching the second groove 19, and the outer wall of the clamping block 23 is provided with a clamping groove 24 matching the top block 21.

[0036] In this embodiment: after the twisting block 17 finishes rotating, the twisting block 17 is pressed, and the twisting block 17 drives the clamping block 23 to enter the second groove 19, and the top block 21 is squeezed into the third groove 20 through the clamping block 23. At the same time, the top block 21 compresses the spring 22. When the clamping block 23 completely enters the second groove 19, the clamping groove 24 is flush with the top block 21, and then the spring 22 rebounds, pushing the top block 21 into the clamping groove 24, and clamping the clamping block 23 into the second groove 19, thereby limiting the twisting block 17 to prevent the twisting block 17 from driving the screw rod 14 to rotate at will.

[0037] As a technical optimization solution of the present invention, the moving block 15 and the plurality of inclined plates 16 are slidably connected via trapezoidal sliding blocks and trapezoidal sliding grooves.

[0038] In this embodiment, the moving block 15 and the multiple inclined plates 16 are slidably connected via a trapezoidal slider and a trapezoidal chute. The trapezoidal slider and the trapezoidal chute can limit the moving block 15 while enabling the moving block 15 to drive the multiple inclined plates 16 to move.

[0039] As a technical optimization solution of the present invention, the first groove 18 and the screw rod 14 are slidably connected via a limiting sliding groove and a limiting sliding block.

[0040] In this embodiment: the first groove 18 and the screw rod 14 are slidably connected by a limiting slide groove and a limiting slider. The limiting slide groove and the limiting slider can limit the screw rod 14 to prevent the screw rod 14 from sliding out of the first groove 18, and can enable the torsion block 17 to move back and forth while driving the screw rod 14 to rotate.

[0041] As a technical optimization solution of the present invention, the movable plate 9 and the sector groove 6 are slidably connected via a trapezoidal slider and a trapezoidal sliding groove.

[0042] In this embodiment, the movable plate 9 and the fan-shaped groove 6 are slidably connected via a trapezoidal slider and a trapezoidal slide groove, which can prevent the movable block 15 from rotating with the screw rod 14 while driving the multiple inclined plates 16 to move outward.

[0043] As a technical optimization solution of the present invention, the upper end of the material discharge shell 3 is connected to a material storage trough 25.

[0044] In this embodiment, the storage tank 25 can temporarily store inorganic sand and gravel.

[0045] Working principle: When in use, two different inorganic sands and gravels are respectively placed in the two storage troughs 25, and then the motor 11 is started. The motor 11 drives the two driving wheels 12 to rotate. The two driving wheels 12 cooperate with the two belts 13 to drive the two driven wheels 10 to rotate. The two driven wheels 10 drive the two unloading rollers 4 to rotate. When the two unloading rollers 4 rotate, the inorganic sands and gravels enter the fan-shaped groove 6. The inorganic sands and gravels are quantitatively proportioned through the mutual cooperation between the unloading rollers 4 and the fan-shaped groove 6. Through the mutual cooperation between the two driving wheels 12, the two belts 13 and the two driven wheels 10, the two unloading rollers 4 can be driven to rotate by one motor 11, thereby reducing the production cost of the proportioning machine and reducing the operating energy consumption of the proportioning machine.

[0046] When the mixing amounts of two different inorganic sand and gravel are different, the depth of the multiple sector grooves 6 on the inorganic sand and gravel feeding roller 4 with a smaller mixing amount is adjusted according to the feeding time of the inorganic sand and gravel with a larger mixing amount, so that the amount of inorganic sand and gravel in the sector groove 6 after the adjustment is reduced, thereby slowing down the feeding efficiency of the inorganic sand and gravel with a smaller mixing amount, making the feeding time of the two inorganic sand and gravel with different mixing amounts the same, thereby quantitatively proportioning the two inorganic sand and gravel with different mixing amounts;

[0047] When the depth of the fan-shaped groove 6 is adjusted, the screw rod 14 is rotated by the torsion block 17, and the screw rod 14 drives the moving block 15 to move. When the moving block 15 moves, since the moving plate 9 and the fan-shaped groove 6 are slidably connected by the trapezoidal slider and the trapezoidal slide, the mutual cooperation between the trapezoidal slider and the trapezoidal slide can prevent the moving block 15 from following the rotation of the screw rod 14, while driving multiple inclined plates 16 to move outward, and multiple inclined plates 16 drive multiple adjusting plates 7 to move outward, so that the adjusting plate 7 is close to the opening of the fan-shaped groove 6, thereby reducing the depth of the fan-shaped groove 6. When the adjusting plate 7 moves, since the moving plate 9 and the fan-shaped groove 6 are slidably connected by the trapezoidal slider and the trapezoidal slide, the mutual cooperation between the trapezoidal slider and the trapezoidal slide drives the two moving plates 9 to extend to the two sides of the adjusting plate 7, and the bottom of the fan-shaped groove 6 is blocked by the mutual cooperation between the two moving plates 9 and the adjusting plate 7, thereby adjusting the depth of the fan-shaped groove 6.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
