Description

Technical Field

[0001] This utility model relates to the field of water-stabilized layer construction technology, specifically a paving mechanism for water-stabilized layer construction. Background Technology

[0002] A paver for water-stabilized layer construction is a specialized piece of equipment used for laying cement-stabilized materials for road base courses. It primarily uses a auger distributor to evenly spread the material, followed by initial compaction and leveling by a vibrating screed. It offers advantages such as continuous operation, high efficiency, and good flatness, effectively reducing manual intervention and making it a key machine for ensuring the quality of water-stabilized layers in modern road construction.

[0003] A paver for water-stabilized layer construction disclosed in Chinese Patent Publication No. CN215441323U, in which the drive mechanism drives the conveying auger to rotate, conveys the material to various positions in the conveying trough, so that the material can be evenly conveyed from the paving opening, achieving uniform paving. When the auger reverses direction at the column connection section, the material at that point can be pushed in the opposite direction for a certain distance, avoiding material accumulation at the column and thus preventing segregation of coarse aggregate. However, the overall functionality of the paving mechanism is low, and it is not convenient to effectively compact the paved road surface after paving, affecting both the overall practicality of the paver and the overall aesthetics of the road surface. Utility Model Content

[0004] The purpose of this invention is to provide a paving mechanism for water-stabilized layer construction to solve the problems mentioned in the background art.

[0006] Preferably, the rotating mechanism includes a second motor fixedly connected to the rear end of the left side of the fixed seat, a first chain disk is mounted on the output shaft end of the second motor, a connecting chain is externally engaged with the first chain disk, a second chain disk is externally engaged with the bottom end of the connecting chain, and a pressure roller rotating inside the fixed seat is fixedly connected to the front end of the second chain disk.

[0007] Preferably, the pressure roller is made of high-carbon steel with surface heat treatment.

[0008] Preferably, the compaction mechanism includes a first gear fixed to the front end of a first chain disc, a through groove on the right side inside the fixed seat, a rotating rod rotatably connected inside the through groove, a second gear fixed to the rear end outside the rotating rod, the left side of the second gear meshing with the first gear, a toggle block fixed to the outside of the rotating rod, a movable plate slidably connected to the bottom end inside the through groove, the front and rear ends of the lower surface of the movable plate fixed to the fixed arm, and a first spring evenly and longitudinally fixed to the bottom end of the movable plate at equal intervals.

[0009] Preferably, the installation mechanism includes a connecting groove inside the lower surface of the fixed arm, a movable groove at the bottom of the fixed arm, an auxiliary groove on the upper surface of the movable groove, a first magnetic block slidably connected inside the movable groove, a magnetic rod fixedly connected to the inner side of the first magnetic block, connecting blocks fixedly connected to the front and rear ends of the upper surface of the compaction seat, the connecting blocks engaging with the connecting groove at the bottom of the fixed arm, a positioning groove engaging with the magnetic rod at the center inside the connecting block, a second spring fixedly connected to the bottom of the auxiliary groove, a second magnetic block fixedly connected to the top of the second spring, and a pull block fixedly connected to the outside of the second magnetic block, the pull block sliding on the outside of the fixed arm.

[0010] Preferably, the connecting block is made of magnetic material, and the connecting block and the magnetic rod are attracted by magnetic force. The magnetic force of the second magnetic block is greater than the magnetic force generated by the magnetic rod, and the contact surfaces of the second magnetic block and the first magnetic block are magnetically attracted.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of paving mechanism for water-stabilized layer construction has a rotating mechanism installed on one side inside the fixed base. When the second motor on the rotating mechanism is started, it can drive the first chain disc to rotate. At this time, the first chain disc drives the second chain disc to rotate through the connecting chain. The pressure roller on one side of the second chain disc can efficiently roll the paved road surface. At the same time, the rotation of the first chain disc can drive the second gear on the rotating rod through the first gear. At this time, the actuating block on the rotating rod can repeatedly push the movable plate downward, and the movable plate drives the compaction seat through the fixed arm to compact the paved road surface. This improves the overall functionality of the paving mechanism while ensuring the overall use effect of the paving mechanism.

[0013] 2. This type of paving mechanism for water-stabilized layer construction features connecting blocks on both sides of the top of the compaction seat. When the connecting blocks are inserted into the connecting grooves at the bottom of the two sets of fixed arms, and the magnetic rods in the connecting grooves are inserted into the positioning grooves on the connecting blocks, the compaction seat can be fixed in position at the bottom of the fixed arms. When maintenance or replacement of the compaction seat is required, pulling the pull block downwards will cause the pull block to move the second magnetic block downwards. At this time, the magnetic force generated by the second magnetic block can attract the first magnetic block on one side of the magnetic rod, causing the first magnetic block to pull the magnetic rod out of the positioning groove on the connecting block, thus completing the quick disassembly of the compaction seat. The operation is simple and convenient, and the modular design improves the flexibility of replacing paving mechanism parts and extends the overall service life of the paving mechanism.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides two technical solutions:

[0022] Example 1: A paving mechanism for water-stabilized layer construction includes a conveying trough 1. A first motor 101 is installed at the center of the upper surface of the conveying trough 1. A reducer 102 is installed at the output shaft end of the first motor 101. Conveying augers 103 rotating inside the conveying trough 1 are installed on both sides of the reducer 102. The threads of the two conveying augers 103 face opposite directions. A fixed seat 2 is fixedly connected to the left side of the conveying trough 1. A partition 201 is fixedly connected to the right side of the lower surface of the fixed seat 2. The partition 201 is used for discharging water-stabilized layer material. A rotating mechanism 3 is provided on the left side inside the fixed seat 2. A compaction mechanism 4 is also included. The compaction mechanism 4 is used to compact the road surface after paving. Fixed arms 6 are provided on the front and rear sides of the bottom end of the compaction mechanism 4. A compaction seat 7 is provided at the bottom end of the fixed arm 6. It also includes an installation mechanism 8, which is used to disassemble and replace the compaction seat 7. The first motor 101 can drive the conveying augers 103 on both sides to rotate through the reducer 102. Thus, the conveying augers 103 can evenly discharge the paving material that has entered the conveying trough 1. The specific installation method, circuit connection method and control method of the conveying trough 1 and the first motor 101 are all conventional designs and will not be described in detail in this work.

[0023] The rotating mechanism 3 includes a second motor 301 fixed to the rear left side of the fixed base 2. A first chain disk 302 is mounted on the output shaft end of the second motor 301. A connecting chain 303 is externally engaged with the first chain disk 302. A second chain disk 304 is externally engaged with the bottom end of the connecting chain 303. A pressure roller 305 rotating inside the fixed base 2 is fixed to the front end of the second chain disk 304. When the second motor 301 is started, it can drive the first chain disk 302 to rotate. At this time, the connecting chain 303 outside the first chain disk 302 can drive the second chain disk 304 to rotate, and the second chain disk 304 drives the pressure roller 305 to rotate.

[0024] The pressure roller 305 is made of high-carbon steel with surface heat treatment. Through surface quenching and overall tempering processes, the hardness and wear resistance of the pressure roller 305 are improved, while maintaining internal toughness and preventing cracking.

[0025] The compaction mechanism 4 includes a first gear 306 fixedly connected to the front end of the first chain disc 302. A through groove 401 is provided on the right side inside the fixed base 2. A rotating rod 402 is rotatably connected inside the through groove 401. A second gear 403 is fixedly connected to the rear end of the rotating rod 402. The left side of the second gear 403 meshes with the first gear 306. A toggle block 404 is fixedly connected to the outside of the rotating rod 402. A movable plate 5 is slidably connected to the bottom end inside the through groove 401. The front and rear ends of the lower surface of the movable plate 5 are fixedly connected to the fixed arm 6. The bottom end of the movable plate 5 is equidistant from the fixed arm 6. A first spring 501 is uniformly and longitudinally fixed. The first chain disk 302 drives the first gear 306 to rotate. Then the second chain disk 304 can push the second gear 403 on the rotating rod 402. At this time, the rotating rod 402 drives the actuating block 404 to rotate, which can make the actuating block 404 repeatedly push the movable plate 5 downward. At the same time, the movable plate 5 is subjected to force that can squeeze the first spring 501 below. Due to the reaction force of the first spring 501 being squeezed, when the actuating block 404 leaves the surface of the movable plate 5, it can push the movable plate 5 to reset.

[0026] Example 2 differs from Example 1 mainly in that:

[0027] A paving mechanism for water-stabilized layer construction includes an installation mechanism 8 comprising a connecting groove 601 inside the lower surface of a fixed arm 6, a movable groove 602 at the bottom end of the fixed arm 6, an auxiliary groove 603 on the upper surface of the movable groove 602, a first magnetic block 604 slidably connected inside the movable groove 602, a magnetic rod 605 fixedly connected to the inner side of the first magnetic block 604, connecting blocks 701 fixedly connected to the front and rear ends of the upper surface of the compaction seat 7, the connecting blocks 701 engaging with the connecting groove 601 at the bottom end of the fixed arm 6, a positioning groove 702 for engaging with the magnetic rod 605 being formed in the center of the connecting block 701, and a second spring 801 fixedly connected to the bottom end of the auxiliary groove 603. A second magnetic block 802 is fixedly connected to the top of the second spring 801. A pull block 803 is fixedly connected to the outside of the second magnetic block 802. The pull block 803 slides on the outside of the fixed arm 6. When the connecting block 701 is inserted into the connecting groove 601 on the fixed arm 6, the magnetic rod 605 can be inserted into the positioning groove 702 on the connecting block 701 due to the magnetic force, thus completing the limiting of the compaction seat 7 at the bottom of the fixed arm 6. When the pull block 803 drives the second magnetic block 802 to move into the interior of the movable groove 602, the first magnetic block 604 can be attracted due to the magnetic force of the second magnetic block 802, and the first magnetic block 604 drives the magnetic rod 605 to be pulled out from the connecting block 701 on the compaction seat 7.

[0028] The connecting block 701 is made of magnetic material. The connecting block 701 and the magnetic rod 605 are attracted by magnetic force. The magnetic force of the second magnetic block 802 is greater than that generated by the magnetic rod 605. The contact surfaces of the second magnetic block 802 and the first magnetic block 604 are magnetically attracted. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] In this embodiment of the application, the material to be paved is poured into the interior of the conveying trough 1 through the top of the conveying trough 1. At this time, the first motor 101 starts and drives the conveying auger 103 to rotate through the reducer 102. The conveying auger 103 can evenly spread the paving material into the conveying trough 1. The conveying trough 1 is moved by an external tractor. The material in the conveying trough 1 can be discharged through the bottom end of the partition 201 on one side of the fixed seat 2. At the same time, the second motor 301 starts and drives the first chain disc 302 to rotate. At this time, the first chain disc 302 drives the second chain disc 304 to rotate through the connecting chain 303. The second chain disc 304 can drive the pressure roller 305 on one side to rotate and make the pressure roller 305 roll the road surface. At the same time, the first gear 306 on one side of the first chain disc 302 pushes the second gear 403 on the rotating rod 402 to rotate. The actuating block 404 on the rotating rod 402 can repeatedly push the movable plate 5 downward. Thus, the movable plate 5 can drive the compaction seat 7 through the fixed arm 6 to quickly compact the paved road surface.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
