[0014] The present invention also discloses a stirring method of a multifunctional highway material screening system, which specifically comprises the following steps:

[0015] Step 1: The user starts the first motor, and the first motor drives the rotating frame, the stirring rod, and the screening element to rotate through the gear ring assembly, and the crushed road materials are introduced into the shell through the feed hopper. The crushed materials introduced into the shell fall on the filter plate in the screening element, and the filter plate squeezes the extended end of the first damper and the first spring. The extended end of the first damper and the first spring contract, and the reaction force generated by the compression deformation of the first spring provides buffering for the filter plate and the material on its upper end, and the rotating filter plate screens the crushed materials on its upper end, and the screened materials fall onto the baffle at the bottom of the shell through the filter plate, and the rotating stirring rod stirs the screened materials, while promoting uniform mixing of different crushed materials and avoiding material blockage;

[0016] Step 2: In step 1, after the first spring provides buffering for the filter plate and the material, the first bevel gear assembly is started, and the first bevel gear assembly drives the two sets of second motors to rotate through the connecting shaft, and the two sets of second motors drive the two screws to rotate, and the two rotating screws respectively drive the two top blocks to move upward, and the top blocks contact the lower edge of the filter plate to lift the filter plate and the material on its upper end, so as to facilitate the subsequent discharge of the material. After the filter plate is reset, the first bevel gear assembly is closed, and after the material screening is completed, the first motor is closed, and the auxiliary cylinder is started, and the auxiliary cylinder drives the partition to shrink, and the second cylinder assembly is started. The second cylinder assembly drives the push plate to move toward the discharge shell, and the push plate pushes the residual material retained on the filter plate when passing through the filter plate. Finally, the residual material on the filter plate falls into the conveying shell through the discharge shell under the push of the push plate, and a recovery box is set at the bottom of the discharge pipe on the lower side of the conveying shell;

[0017] Step 3: In step 2, during the material unloading process on the filter plate, start the micro cylinder assembly, which drives the support frame, driven frame, and connecting pin to move along the outer tooth end of the driving block. After the connecting pin is inserted into the driving slot in the conveying assembly, close the micro cylinder assembly and start the first motor. The first motor drives the driving block, driven frame, and connecting pin through the second bevel gear assembly to drive the conveying assembly to operate. At this time, the auger column in the conveying assembly rotates under the action of the connecting pin, and the rotating connecting pin conveys the material in the conveying shell. After the material is moved to the right side of the conveying shell, At this time, the material is discharged from the discharge pipe on the lower right side of the conveying shell and falls into the recovery box. At the same time, the auger column drives the turntable to rotate through the third bevel gear assembly, and the turntable drives the impact piece to reciprocate in the horizontal direction through the traction rod. The reciprocating impact piece impacts the outer surface of the discharge shell. The discharge shell vibrates under the impact of the impact piece to promote the material attached to the inner end of the discharge shell to fall off. The air pump is started, and the air pump draws in the outside air and injects it into the jet plate on the push plate through the conduit. The jet plate sprays gas to blow the material attached to the discharge shell on the right side of the push plate to promote the falling of the material.

[0018] Preferably, in step three, when the impact piece impacts the blanking shell, the impact block at the inner end of the impact piece first contacts the blanking shell, and under the reaction force of the blanking shell, the impact block squeezes the extended end of the second damper and the second spring, promoting the contraction of the extended end of the second damper and the second spring, thereby avoiding damage to the blanking shell due to continuous impact.

[0019] Beneficial Effects

[0020] The present invention provides a multifunctional road material screening system and mixing method. Compared with the prior art, it has the following beneficial effects:

[0021] (1) The multifunctional highway material screening system, by arranging screening elements and reset elements in the device, introduces the crushed highway materials into the shell through the feed hopper, and the crushed materials introduced into the shell fall onto the filter plate in the screening element. The reaction force generated by the compression and contraction of the filter plate by the extended end of the first damper and the first spring provides buffering for the filter plate and the materials on its upper end. After providing buffering for the materials and the materials falling off is completed, the first bevel gear assembly is started, and the first bevel gear assembly drives two sets of second motors to rotate through the connecting shaft, and the two sets of second motors drive two screws to rotate. The two rotating screws respectively drive two top blocks to move upward to lift the filter plate and the materials on its upper end, so as to facilitate the subsequent discharge of materials.

[0022] (2) The multifunctional highway material screening system is provided with a transmission part in the device. During the material discharge process on the filter plate, the micro-cylinder assembly is started, and the micro-cylinder assembly drives the support frame, the driven frame, and the connecting pin to move along the outer tooth end of the driving block. After the connecting pin is inserted into the driving groove in the conveying assembly, the micro-cylinder assembly is closed; the first motor is started, and the first motor drives the driving block, the driven frame, and the connecting pin to drive the conveying assembly to operate through the second bevel gear assembly. At this time, the auger column in the conveying assembly rotates under the action of the connecting pin, and the rotating connecting pin conveys and discharges the material in the conveying shell. At the same time, the auger column drives the turntable to rotate through the third bevel gear assembly, and the turntable drives the impact member to reciprocate in the horizontal direction through the traction rod. The reciprocating impact member impacts the outer surface of the discharge shell, and the discharge shell vibrates under the impact of the impact member to promote the material attached to the inner end of the discharge shell to fall off.

[0023] (3) The multifunctional highway material screening system is provided with an impact member in the device. When the impact member impacts the material shell, the impact block at the inner end of the impact member first contacts the material shell. Under the reaction force of the material shell, the impact block squeezes the extended end of the second damper and the second spring, thereby promoting the contraction of the extended end of the second damper and the second spring, thereby avoiding damage to the material shell due to continuous impact.

[0024] (4) The multifunctional highway material screening system is provided with an air pump and a three-way valve in the device. After the push plate guides the materials retained on the screening element into the conveying shell through the discharge shell, the air pump is started. The air pump draws in outside air and injects it into the jet plate on the push plate through the conduit. The jet plate sprays gas to blow the materials attached to the discharge shell on the right side of the push plate, thereby promoting the falling of the materials. After the device has finished screening the materials and discharged the screened materials and filtered out the materials, the three-way valve is reversed. At this time, the gas generated by the air pump is injected into the jet ring through the three-way valve, branch pipe, ventilation frame, and ventilation groove. The first motor is started. The first motor drives the stirring rod and the jet ring to rotate through the gear ring assembly and the rotating frame. The jet ring sprays gas to blow the materials attached to the stirring end of the stirring rod and the lower end of the shell, thereby promoting the falling of impurities and reducing the subsequent cleaning steps.

The crushed materials introduced into the shell 1 fall on the filter plate 93 in the screening member 9, and the filter plate 93 squeezes the extended end of the first damper 91 and the first spring 92. The extended end of the first damper 91 and the first spring 92 contract, and the reaction force generated by the compression deformation of the first spring 92 provides a buffer for the filter plate 93 and the materials on its upper end, and the rotating filter plate 93 screens the crushed materials on its upper end, and the screened materials fall onto the baffle 4 at the bottom of the shell 1 through the filter plate 93, and the rotating stirring rod 8 stirs the screened materials, while promoting uniform mixing of different crushed materials and avoiding material blockage;

[0050] Step 2: In step 1, after the first spring 92 has provided buffering for the filter plate 93 and the material, the first bevel gear assembly 953 is started, and the first bevel gear assembly 953 drives the two sets of second motors 952 to rotate through the connecting shaft 951, and the two sets of second motors 952 drive the two screw rods 954 to rotate, and the two rotating screw rods 954 respectively drive the two top blocks 955 to move upward, and the top blocks 955 contact the lower edge of the filter plate 93 to lift the filter plate 93 and the material on the upper end thereof, so as to facilitate the subsequent discharge of the material, and wait for the filter plate 93 to be reset. After that, the first bevel gear assembly 953 is closed. After the material screening is completed, the first motor 5 is closed, the auxiliary cylinder is started, the auxiliary cylinder drives the partition plate 10 to shrink, the second cylinder assembly 13 is started, and the second cylinder assembly 13 drives the push plate 14 to move toward the discharge shell 11. When the push plate 14 passes through the filter plate 93, it pushes the residual material retained on the filter plate 93. Finally, the residual material on the filter plate 93 falls into the conveying shell 12 through the discharge shell 11 under the push of the push plate 14, and a recovery box is set at the bottom of the discharge pipe on the lower side of the conveying shell 12;

[0051] Step 3: In step 2, during the material unloading process on the filter plate 93, the micro cylinder assembly 966 is started, and the micro cylinder assembly 966 drives the support frame 967, the driven frame 963, and the connecting pin 964 to move along the outer tooth end of the driving block 962. After the connecting pin 964 is inserted into the driving groove in the conveying assembly 965, the micro cylinder assembly 966 is closed, and the first motor 5 is started. The first motor 5 drives the driving block 962, the driven frame 963, and the connecting pin 964 to drive the conveying assembly 965 to operate through the second bevel gear assembly 961. At this time, the auger column 9651 in the conveying assembly 965 rotates under the action of the connecting pin 964, and the rotating connecting pin 964 conveys the material in the conveying shell 12. After the material is transferred to the conveying When the material moves to the right side of the delivery shell 12, the material is discharged from the discharge pipe in the lower right side of the delivery shell 12 and falls into the recovery box. At the same time, the auger column 9651 drives the turntable 9653 to rotate through the third bevel gear assembly 9652, and the turntable 9653 drives the impact member 9655 to reciprocate in the horizontal direction through the traction rod 9654. The reciprocating impact member 9655 impacts the outer surface of the discharge shell 11. The discharge shell 11 vibrates under the impact of the impact member 9655 to promote the falling of the material attached to the inner end of the discharge shell 11, and the air pump 15 is started. The air pump 15 draws in the outside air and injects it into the jet plate on the push plate 14 through the conduit. The jet plate sprays gas to blow the material attached to the discharge shell 11 on the right side of the push plate 14 to promote the falling of the material.

[0052] At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art. In step three, when the impact member 9655 impacts the discharge shell 11, the impact block 96554 at the inner end of the impact member 9655 first contacts the discharge shell 11, and under the reaction force of the discharge shell 11, the impact block 96554 squeezes the extended end of the second damper 96552 and the second spring 96553 to promote the contraction of the extended end of the second damper 96552 and the second spring 96553, thereby avoiding damage to the discharge shell 11 due to continuous impact.
