Description

Technical Field

[0001] The invention relates to the technical field of crushing and screening equipment for road and bridge construction, and in particular to an integrated crushing and screening machine used in road and bridge construction. Background Art

[0002] Road and bridge construction covers road and bridge engineering, aiming to build a transportation network. Road construction starts from planning and line selection, through site cleaning, roadbed filling and compaction, road base and surface paving, to create a traffic structure that carries vehicles and pedestrians; bridge construction involves foundation construction, pier and abutment construction, bridge erection, etc., across rivers, valleys and other obstacles. Various types of machinery are used in construction, such as excavators digging soil and crushers processing materials, while quality and safety are controlled. The completed roads and bridges promote regional exchanges and drive economic development. The motor is a device that converts electrical energy into mechanical energy. It operates based on the principle of electromagnetic induction. After power is turned on, the stator generates a rotating magnetic field, which drives the rotor to rotate synchronously, and then outputs mechanical energy to drive various equipment. There are various types of motors, such as AC motors are widely used, and DC motors have good speed regulation performance. It has the advantages of simple structure, reliable operation, and high efficiency. It is an indispensable power source in industrial production and daily life.

[0003] In the process of road and bridge construction, according to the needs of construction, natural stones, construction waste, industrial slag or metal ore need to be crushed and processed, and according to the needs of subsequent construction, they need to be screened for subsequent operations. In this process, crushers and screens are needed. Existing crushers and screens are generally two types of equipment, which need to add connection processes required for transportation, so they cannot be operated on the spot or nearby, which reduces the efficiency of crushing and screening. In addition, since crushers and screens usually use electric motors as power sources during operation, the power consumed by the operation is large, and more power is consumed during start and stop. When the equipment stops, the kinetic energy drive continues to rotate due to the inertia of the flywheel, and the kinetic energy recovery cannot be used to assist braking and speed reduction. The auxiliary coordination function cannot be achieved. A lot of energy is wasted over time, so the energy saving and environmental protection of the motor cannot be achieved.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 11The present invention provides a technical solution: a crushing and screening integrated machine used in road and bridge construction, comprising a screening box 1 and a kinetic energy recovery mechanism 12, the top of the screening box 1 is connected to a crushing box 2, a feeding box 3 is fixedly sleeved on the inner side of the top of the crushing box 2, a discharging mechanism 11 is arranged at the output end of the feeding box 3, a preliminary crushing mechanism 6 is movably installed inside the crushing box 2, a driving mechanism 4 is arranged on one side of the screening box 1, a main jaw crushing mechanism 5 is installed inside the screening box 1, a plurality of discharging mechanisms 7 are arranged at both ends of the screening box 1, a battery box 8 is fixedly installed on the top of the screening box 1, an electrical control box 9 is fixedly installed on the top of the screening box 1, an airflow processing mechanism 10 is fixedly installed on the top of the screening box 1, and a screening mechanism 13 is movably installed inside the screening box 1.

[0033] The kinetic energy recovery mechanism 12 includes a generator 1201 and a rotating shaft 1205. The input end of the generator 1201 is transmission-connected to a driving wheel ring 1202. A driving belt 1203 is sleeved on the outer side of the driving wheel ring 1202. A driven wheel 1204 is sleeved on the other end of the driving belt 1203. Two bearing brackets 1207 are movably sleeved on the outer side of the middle part of the rotating shaft 1205. A plurality of straight tooth grooves 1206 are provided on the outer sides of both ends of the rotating shaft 1205. An inner rack sleeve 1217 is movably sleeved on the outer sides of both ends of the rotating shaft 1205 through the straight tooth grooves 1206. A magnetic coupler driven end 1218 is fixedly mounted on the opposite ends of the inner rack sleeve 1217.

[0034] The working principle of the above technical solution is as follows: when in use, the user puts the stones pre-crushed by the excavator or manually into the inner side of the feeding box 3, and then opens the discharge mechanism 11 to make the stones fall into the inner side of the crushing box 2, and then starts the driving mechanism 4 to drive the main jaw crushing mechanism 5 and the preliminary crushing mechanism 6 to rotate. The stones are first squeezed through the inner gap of the preliminary crushing mechanism 6 for pre-crushing, and then crushed by the jaw crushing mechanism of the main jaw crushing mechanism 5, and finally fall on the top of the screening mechanism 13. After being graded by the vibrating screen of the screening mechanism 13, they are discharged and collected respectively through the discharging mechanism 7. As the operation progresses, the stones are crushed by the discharge mechanism 7. The airflow handling mechanism 10 is opened and the discharge mechanism 11 is closed to suck the inside of the screening box 1 to reduce the spillage of dust. Finally, when the rotation speed of the adjustment driving mechanism 4 is reduced or stopped, the kinetic energy of the rotation is recovered through the kinetic energy recovery mechanism 12, and the generated electric energy is stored in the battery box 8 to power the screening mechanism 13 and the airflow handling mechanism 10, thereby realizing the kinetic energy recovery and energy-saving effect of the drive motor, reducing the use of electric energy, and the overall structure has good use effect and high screening efficiency. The closed structure will not affect the working environment, while protecting the safety of the operators.

[0035] In another embodiment, Figure 1-Figure 10As shown, the discharge mechanism 11 includes two electrically controlled telescopic rods 1101, an arc-shaped switch door 1102 and a limit support bar 1103. One end of the two electrically controlled telescopic rods 1101 is hinged on the inner wall of the crushing box 2, and the output ends of the two electrically controlled telescopic rods 1101 are hinged on the opposite ends of the arc-shaped switch door 1102. The two arc-shaped switch doors 1102 are slidably installed on the opposite sides of the feeding box 3 and the limit support bar 1103. The two arc-shaped switch doors 1102 are arc-shaped, and the specifications and dimensions of the arc-shaped switch doors 1102 are compatible with the specifications and dimensions of the feeding box 3 and the limit support bar 1103. The two limit support bars 1103 are fixedly installed on the inner wall of the crushing box 2, and both ends of the two arc-shaped switch doors 1102 are slidably installed on the opposite sides of the limit support bar 1103 and the feeding box 3.

[0036] When it is necessary to put down the stone, the electrically-controlled telescopic rod 1101 is started to retract, and the hinged arc-shaped switch door 1102 is driven to move. The arc-shaped switch door 1102 slides under the limit of the limit support bar 1103 and the feeding box 3, causing the opposite ends of the arc-shaped switch door 1102 to open a certain gap, so that the stone falls into the inside of the crushing box 2, which is convenient for opening and closing the feeding box 3 to discharge the material, and to control the feeding and closing to avoid dust overflow.

[0037] In another embodiment, Figure 1-Figure 8 As shown, the preliminary crushing mechanism 6 includes two central shafts 604, both ends of which are movably installed in the crushing box 2 through bearings, and the outer sides of the two central shafts 604 are respectively fixedly sleeved with active meshing gear rollers 601 and auxiliary gear rollers 602, and gaps are left on the opposite sides of the active meshing gear rollers 601 and auxiliary gear rollers 602 and are distributed in a meshing state on the inner side of the crushing box 2, one end of the two central shafts 604 is fixedly installed with a meshing transmission gear plate 603, and the ends of the two central shafts 604 away from the meshing transmission gear plate 603 are fixedly installed with a transmission wheel 605.

[0038] When the preliminary crushing mechanism 6 receives the power output of the driving mechanism 4, the driving wheel 605 is driven to rotate through the power transmission of the driving mechanism 4, and the driving wheel 605 applies a force to the central shaft 604. The central shaft 604 is meshed with the meshing transmission gear plate 603, so that the two central shafts 604 maintain relative rotation, thereby making the active meshing gear roller 601 and the auxiliary gear roller 602 on the outer side of the central shaft 604 realize relative extrusion, and then the stones and other recycled materials are squeezed and broken through the gap extrusion, so that the recycled materials are preliminarily processed and crushed, which increases the effect of subsequent crushing and facilitates to increase the crushing efficiency.

[0040] When power output is performed, the double-headed driving motor 401 starts to rotate, driving the driving wheel 402 to rotate, and the main jaw crushing mechanism 5 is driven to rotate through the driving wheel 402, and the auxiliary output wheel 404 and the transmission belt 2 403 drive the transmission wheel 605 to realize power output to the preliminary crushing mechanism 6, thereby facilitating power output and increasing the relative stability of the structure.

[0041] In another embodiment, Figure 1-Figure 8 As shown, the main jaw crusher mechanism 5 includes a movable jaw crusher mechanism 503, a static jaw crusher mechanism 504 and an eccentric driving shaft 505 for the jaw crusher. The outer side of the eccentric driving shaft 505 of the jaw crusher is eccentrically connected to the inner side of the movable jaw crusher mechanism 503. Both ends of the movable jaw crusher mechanism 503 movably penetrate the screening box 1 through bearings and extend to the outer side of the screening box 1. The outer side of the movable jaw crusher mechanism 503 is assisted by a flexible connection and mounted on the inner wall of the screening box 1. The static jaw crusher mechanism 504 is fixed to the inner wall of the screening box 1 through an adjustable mechanism. The static jaw crusher mechanism 504 and the movable jaw crusher mechanism 503 are relatively close to each other. Both ends of the eccentric driving shaft 505 of the jaw crusher are fixedly mounted with a driven flywheel disc 501. The outer side of the driven flywheel disc 501 is movably sleeved with a plurality of transmission belts 502. The end of the transmission belt 502 away from the driven flywheel disc 501 is sleeved on the outer side of the driving wheel disc 402.

[0042] When the main jaw crusher mechanism 5 is subjected to power output operation, the driving wheel 402 drives the transmission belt 502 to rotate through the transmission, and then drives the driven flywheel 501 and the eccentric driving shaft 505 of the jaw crusher to rotate through the transmission belt 502, and then drives the movable jaw crusher mechanism 503 to move circularly through the eccentric driving shaft 505 of the jaw crusher, and the movable jaw crusher mechanism 503 squeezes the static jaw crusher mechanism 504, thereby squeezing and crushing the recycled materials, so as to subsequently crush the recycled materials pre-extruded and split by the preliminary crushing mechanism 6, and the crushed recycled materials fall on the top of the screening mechanism 13 inside the screening box 1, which is convenient for subsequent operations.

[0043] In another embodiment, Figure 1-Figure 4As shown, the airflow processing mechanism 10 includes an air pump 1001, a dust filter 1002 and an air inlet pipe 1003. The air pump 1001 is fixedly installed on the top of the screening box 1, the input end of the air pump 1001 is connected to the air inlet pipe 1003, one end of the air inlet pipe 1003 away from the air pump 1001 is connected to the top of the inner cavity of the screening box 1, and the output end of the air pump 1001 is connected to the input end of the dust filter 1002 through a pipeline.

[0044] When crushing and screening operations are carried out, a lot of dust will be generated.
