Description

Technical Field

[0001] This utility model relates to the field of asphalt production technology, and in particular to an auxiliary material addition device for asphalt production. Background Technology

[0002] An asphalt production additive device is a specialized piece of equipment used in the preparation of asphalt mixtures to classify, store, quantitatively control, and orderly add aggregates such as stones of different specifications. This device typically has multiple independent silos to hold crushed stone or gravel of different particle sizes. Through this device, stones of different specifications can be fed into the mixing system in a set ratio to be fully mixed with the asphalt base material, thereby ensuring that the aggregate gradation of the mixture meets the technical requirements for road construction and improving the structural stability and durability of the pavement.

[0003] Most existing asphalt production auxiliary material addition devices adopt continuous feeding methods and lack timed feeding switching mechanisms. This results in different sizes of aggregates not being able to be switched according to the predetermined time interval and sequence during the addition process, which can easily cause uneven aggregate supply and unbalanced mixing ratio, affecting the gradation accuracy and final quality of asphalt mixtures.

[0004] Therefore, the existing asphalt additives adding devices generally adopt a continuous feeding method and lack a timed switching mechanism, which makes it impossible to accurately add different specifications of stones according to the set time and sequence. This easily leads to uneven material distribution and imbalance, affecting the gradation accuracy of the mixture and the quality of the finished product. There is an urgent need to design a new type of additives adding device for asphalt production. Utility Model Content

[0005] In order to overcome the problem that existing asphalt additive adding devices generally adopt a continuous feeding method and lack a timed switching mechanism, which makes it impossible to accurately feed different specifications of stones according to the set time and sequence, it is easy to cause uneven material distribution and imbalance, which affects the gradation accuracy of the mixture and the quality of the finished product.

[0006] The technical solution of this utility model is as follows: an auxiliary material addition device for asphalt production, including a lifting plate; and an electric motor installed inside the lifting plate, the output end of which is connected to a turntable, the outer end of which is connected with multiple toothed blocks at equal intervals, a rotating column rotatably connected to the top front side of the lifting plate, a gear connected to the top of the rotating column, the gear meshing with the toothed blocks, a triangular plate connected to the top of the gear, a hole being opened at the top triangle of the triangular plate, and a rotating plate rotatably connected to the bottom triangle of the triangular plate via a return shaft, a baffle plate being connected to the end of the rotating plate near the center of the triangular plate. The triangular plate is movably connected to the hole. A limit plate is connected to the bottom triangle of the triangular plate. The limit plate is movably connected to the rotating plate. A storage bin is connected to the top of the triangular plate. A protective plate is connected to the front end of the lifting plate. The protective plate is L-shaped. When the storage bin needs to be switched, the motor drives the turntable to rotate, which drives the gear to rotate through the toothed block. The gear rotates and drives the triangular plate to rotate. The rotation of the triangular plate causes the rotating plate to drive the baffle to hit the protective plate. The baffle rotates through the rotating plate and the auxiliary material falls through the hole. When switching again, the baffle and the protective plate separate. The baffle is reset by the return shaft and the limit plate.

[0007] Preferably, by setting up a turntable structure driven by an electric motor, the outer edge of the turntable is provided with equally spaced toothed blocks that mesh with gears to drive the triangular plates to rotate in sequence. Combined with the linkage between the triangular plates, the rotating plate, the baffle, the return shaft, and the limiting plate, each storage hopper can be opened to feed materials in sequence according to a predetermined time interval and order. This structure can realize the fixed-point release of various auxiliary materials, effectively avoiding the problem of uneven aggregate supply or unbalanced mixing ratio caused by disordered feeding timing or imprecise control, and ensuring the stability of auxiliary material ratio and uniformity of mixing in the asphalt production process.

[0008] Preferably, the lifting plate is internally threaded with a screw, and the outer end of the screw is rotatably connected to a lifting frame.

[0009] Preferably, a motor is connected to the top of the lifting frame, and the output end of the motor is connected to the screw.

[0010] Preferably, the bottom of the lifting frame is connected to a chassis, which is concave and has grooves on the left and right sides of the bottom.

[0011] Preferably, the groove is rotatably connected to three pulleys, and an auxiliary groove is provided on the rear side of the bottom of the chassis.

[0012] Preferably, the auxiliary slot is equipped with casters, and a handle is connected to the top rear side of the chassis.

[0013] Preferably, the motor drives the screw to rotate inside the lifting frame, and the rotation of the screw causes the lifting plate to slide inside the lifting frame. The handle drives the chassis to move in conjunction with the casters and pulleys.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a turntable structure driven by an electric motor, the precise meshing of the turntable teeth and gears drives the triangular plates to rotate in sequence. With the mechanical linkage of components such as the return shaft and limit plate, the storage bins are put into the system in a timely, quantitative, and fixed-point manner. The opening sequence and feeding rhythm of each storage bin are precisely controlled, enabling accurate proportioning and orderly feeding of auxiliary materials in asphalt production. This effectively improves the mixing uniformity and finished product quality of asphalt mixtures. At the same time, the fully automated operation mode reduces manual operation, thereby improving production efficiency and reducing safety risks, ensuring the stability and efficiency of the asphalt production process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment: an auxiliary material addition device for asphalt production, including a lifting plate 1; it also includes a motor 21 installed inside the lifting plate 1, the output end of the motor 21 is connected to a turntable 22, the outer end of the turntable 22 is connected with a plurality of toothed blocks 23 at equal intervals, a rotating column 24 is rotatably connected to the top front side of the lifting plate 1, the top of the rotating column 24 is connected to a gear 25, the gear 25 meshes with the toothed blocks 23, the top of the gear 25 is connected to a triangular plate 26, and the top of the triangular plate 26 has three... A hole is provided at the corner. A rotating plate 27 is rotatably connected to the bottom triangle of the triangular plate 26 via a return shaft. A baffle 28 is connected to the end of the rotating plate 27 near the center of the triangular plate 26. The baffle 28 is movably connected to the hole. A limit plate 29 is connected to the bottom triangle of the triangular plate 26. The limit plate 29 is movably connected to the rotating plate 27. A storage bin 210 is connected to the top of the triangular plate 26. A protective plate 211 is connected to the front end of the lifting plate 1. The protective plate 211 is L-shaped. When it is necessary to switch the storage bin 210, the motor 2... 1. The turntable 22 is driven to rotate, which in turn drives the gear 25 to rotate via the toothed block 23. The rotation of the gear 25 drives the triangular plate 26 to rotate, and the rotation of the triangular plate 26 causes the turntable 27 to drive the baffle 28 to hit the protective plate 211. This causes the baffle 28 to rotate via the turntable 27, allowing the auxiliary material to fall through the hole. When switching again, the baffle 28 separates from the protective plate 211, and the baffle 28 is reset by the return shaft in conjunction with the limiting plate 29. The turntable 22 is driven by the motor 21, and the outer edge of the turntable 22 is provided with equal... The toothed block 23 meshes with the gear 25, driving the triangular plate 26 to rotate in sequence. Combined with the linkage between the triangular plate 26, the rotating plate 27, the baffle 28, the return shaft, and the limiting plate 29, each storage hopper 210 can be opened to feed materials in sequence according to a predetermined time interval. This structure can realize the fixed-point release of various auxiliary materials, effectively avoiding the problem of uneven aggregate supply or unbalanced mixing ratio caused by disordered feeding timing or imprecise control, and ensuring the stability of auxiliary material ratio and uniformity of mixing in the asphalt production process.

[0024] Please see Figures 1-5 In this embodiment, a screw 31 is threadedly connected to the inside of the lifting plate 1. A lifting frame 32 is rotatably connected to the outer end of the screw 31. A motor 33 is connected to the top of the lifting frame 32. The output end of the motor 33 is connected to the screw 31. A chassis 34 is connected to the bottom of the lifting frame 32. The chassis 34 is concave. Grooves 35 are provided on the left and right sides of the bottom of the chassis 34. The screw 31 is driven to rotate by the motor 33. Using the threaded transmission principle, the lifting plate 1 can be precisely driven to slide vertically within the lifting frame 32, realizing flexible adjustment of the height of the lifting plate 1 to meet the height requirements of different working scenarios. The concave chassis 34 design effectively increases the bearing area, so that the device can evenly distribute the load when bearing heavy objects, improving the overall stability.

[0025] Please see Figures 2-5In this embodiment, three pulleys 36 are rotatably connected inside the groove 35. An auxiliary groove 37 is provided on the rear bottom side of the chassis 34, and a universal wheel 38 is provided inside the auxiliary groove 37. A handle 39 is connected to the rear top side of the chassis 34. The motor 33 drives the screw 31 to rotate inside the lifting frame 32. The rotation of the screw 31 causes the lifting plate 1 to slide inside the lifting frame 32. The handle 39 drives the chassis 34 to move in conjunction with the universal wheel 38 and the pulleys 36. The combination of the pulleys 36 and the universal wheel 38 gives the device the ability to move flexibly in multiple directions. The pulleys 36 facilitate lateral sliding, and the universal wheel 38 enables free steering, greatly reducing movement resistance. The rear handle 39 is ergonomically designed, allowing operators to easily push or pull the device, significantly reducing labor intensity. At the same time, the lifting and moving functions can be carried out simultaneously, and the position can be freely adjusted during the height adjustment process, greatly improving work efficiency.

[0026] In the auxiliary material feeding stage, when it is necessary to switch the storage bin 210 to add auxiliary materials, the motor 21 starts and drives the turntable 22 to rotate. Since the equally spaced toothed blocks 23 at the outer end of the turntable 22 mesh with the gear 25, the rotation of the turntable 22 will drive the gear 25 to rotate, thereby causing the triangular plate 26 at the top of the gear 25 to rotate in sequence. During the rotation of the triangular plate 26, the rotating plate 27 connected to the bottom triangle through the return shaft moves accordingly. The rotating plate 27 drives the baffle 28 to hit the L-shaped protective plate 211. At this time, the baffle 28 rotates through the rotating plate 27 under the action of the impact force. The baffle 28, which originally blocked the discharge hole of the storage hopper 210, opens, allowing the auxiliary material to fall smoothly into the designated position through the hole. When it is necessary to switch to the next storage hopper 210, the triangular plate 26 continues to rotate, separating the baffle 28 from the protective plate 211. Under the elastic action of the return shaft and the limiting assistance of the limiting plate 29, the baffle 28 resets and closes the hole, simultaneously driving the baffle 28 of the next storage hopper 210 to repeat the above opening process. This ensures that each storage hopper 210 is accurately fed sequentially according to a predetermined time interval and order, guaranteeing the proper addition of auxiliary materials in asphalt production. For accurate and orderly deployment, when the lifting plate 1 needs to be raised, the motor 33 at the top of the lifting frame 32 drives the screw 31 to rotate. Since the screw 31 and the lifting plate 1 are internally threaded, according to the principle of threaded transmission, the rotation of the screw 31 will precisely drive the lifting plate 1 to slide vertically within the lifting frame 32, thereby achieving flexible adjustment of the height of the lifting plate 1 to adapt to asphalt production equipment or operating scenarios of different heights. At the same time, the concave chassis 34 design increases the load-bearing area, which can evenly distribute the load when the device is carrying heavy objects, improving the overall stability. In addition, the bottom of the chassis 34... The three pulleys 36 in the grooves 35 on both sides of the device cooperate with the casters 38 in the auxiliary groove 37 on the rear side. When the operator pushes or pulls the device by holding the handle 39 on the rear side of the chassis 34, the pulleys 36 facilitate the lateral sliding of the device, while the casters 38 enable free steering. The combination of the two greatly reduces the resistance to movement, allowing the device to move flexibly in multiple directions. Furthermore, the functions of adjusting the height of the lifting plate 1 and moving the device can be performed simultaneously. During the height adjustment process, the operator can move the device position at any time by holding the handle 39, which significantly improves work efficiency.

[0027] Through the above steps, the device uses an electric motor 21 to drive a turntable 22, which in turn drives a triangular plate 26 to rotate through the precise meshing of a toothed block 23 and a gear 25. In conjunction with the mechanical linkage of a return shaft and a limiting plate 29, the device achieves timed and quantitative feeding of the storage hopper 210, accurately controlling the timing and rhythm of auxiliary material feeding. This ensures precise proportioning and orderly feeding of auxiliary materials in asphalt production, significantly improving the uniformity of the mixture and the quality of the finished product. At the same time, the fully automated operation reduces manual operation, improves production efficiency, reduces safety risks, and ensures stable and efficient asphalt production. This addresses the problem that existing asphalt auxiliary material adding devices generally use a continuous feeding method and lack a timed switching mechanism, which leads to different specifications of stones not being accurately fed according to the set time and sequence, easily resulting in uneven material distribution and imbalance, affecting the accuracy of the mixture gradation and the quality of the finished product.
