Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a plate chain bucket unloading device. Background Technology

[0002] Plate chains are continuous chain structures made of high-strength metal plates (such as alloy steel and wear-resistant steel plates) through stamping, forging, or welding, with links connected by pins or hinges. They are characterized by high load-bearing capacity, good tensile strength, and excellent wear resistance. The chain links are designed as flat plates or with specific connection structures, and can be directly fixed to buckets and scraper components. They are widely used in plate chain conveyors, bucket elevators, and unloading devices. They can operate stably under high loads and harsh working conditions (such as dusty, humid, and high-temperature environments), and rely on sprocket drive to achieve cyclical motion, thereby completing the conveying, lifting, or unloading of materials. They are key load-bearing and transmission components in heavy machinery transmission and material handling systems.

[0003] Existing plate chain bucket unloading devices control the unloading speed by adjusting the rotation speed of the plate chain. However, the plate chain rotation speed only adjusts the number of buckets passing through the unloading point per unit time. The actual loading amount of each bucket will vary due to fluctuations in material density and loading uniformity (such as uneven material accumulation causing some buckets to be full while others are underloaded). In this case, rotation speed adjustment alone cannot compensate for the difference in unloading amount of a single bucket. Existing technology installs a high-precision weighing module below the unloading port. When the bucket is unloading, the sensor records the weight of the material in the bucket in real time and uploads it to the control system. However, the material will exert a strong impact on the sensor during the unloading process. Long-term use will cause sensor deformation, decreased sensitivity, and even the need for frequent replacement, significantly increasing the operating cost. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a plate chain bucket unloading device, including a hopper 1. A shielding mechanism 2 is installed in the middle of the hopper 1 to control unloading. A cleaning mechanism 3 is installed in the lower middle part of the hopper 1 to clean dust. The shielding mechanism 2 includes a baffle 201, which is installed in the middle of the hopper 1. The outer wall of the baffle 201 is slidably connected to the inside of the right end of the hopper 1. Racks 202 are fixedly connected to the front and rear sides of the top of the baffle 201. The outer walls of multiple racks 202 are slidably connected to the inside of the right end of the hopper 1. A protective cover 203 is installed on the top outer side of the racks 202. The bottom of the outer wall of the protective cover 203 is fixedly connected to the inner wall of the hopper 1. The outer walls of multiple racks 202 are slidably connected to the inside of the protective cover 203. A drive assembly 204 is installed at the rear outer side of the baffle 201. The drive assembly 204 includes... Servo motor 2041 is installed on the outer rear end of baffle 201. The output end of servo motor 2041 is fixedly connected to drive shaft 2042. Gear teeth 2043 are fixedly connected to the front and rear ends of the outer wall of drive shaft 2042. The bottom of the outer wall of multiple gear teeth 2043 meshes with the top of the outer wall of rack 202. Multiple limiting plates 2044 are equidistantly installed in the middle of the outer wall of drive shaft 2042. The left side of the outer wall of multiple limiting plates 2044 is fixedly connected to the right side of the outer wall of hopper 1. The inside of the right end of limiting plate 2044 is rotatably connected to the outer wall of drive shaft 2042. A support frame 2045 is fixedly connected to the bottom of the outer wall of servo motor 2041. The left end of the outer wall of support frame 2045 is fixedly connected to the right side of the outer wall of hopper 1. A discharge port 4 is opened inside hopper 1. The discharge port 4 is opened at the bottom of the outer side of baffle 201.

[0033] Specifically, when the servo motor 2041 is turned on, its power is transmitted through the drive shaft 2042 to multiple gear teeth 2043 welded to its outer wall, causing the gear teeth 2043 to rotate synchronously. Through the meshing of the gear teeth 2043 with the rack 202, the rack 202 drives the baffle 201 welded outwards to slide inside the right end of the hopper 1. As the baffle 201 moves, it changes its relative position to the discharge port 4, thereby controlling the discharge area of ​​the discharge port 4. When the baffle 201 completely blocks the discharge port 4, the discharge action stops. When the baffle 201 partially moves away, exposing part of the discharge port 4, the material begins to be discharged from the discharge port 4. The size of the exposed area directly determines the unloading speed. The protective cover 203 covers the outside of the rack 202, protecting the rack 202 from direct contact and damage by the material in the hopper 1. The limiting plate 2044 is connected to the drive shaft 2042, which can limit the shaking of the drive shaft 2042 and ensure the stable rotation of the drive shaft 2042. The support frame 2045 is welded to the bottom of the servo motor 2041 and welded to the hopper 1, providing a stable support for the servo motor 2041 and ensuring that the position of the servo motor 2041 remains unchanged during operation. The entire mechanism operates stably with the cooperation of each component, realizing effective control of the unloading speed and the start and stop of unloading.

[0034] Reference Figure 1 , Figure 2 and Figure 6 The cleaning mechanism 3 includes multiple cleaning brushes 301, all of which are installed in the lower middle part of the hopper 1. A threaded frame 302 is fixedly connected to the left side of the outer wall of each cleaning brush 301, and a cooling fan 303 is fixedly connected to the inner wall of the threaded frame 302. A power assembly 304 is installed at the outer front end of each cleaning brush 301. The power assembly 304 includes a second servo motor 3041, which is installed at the outer front end of each cleaning brush 301. A transmission rod 3042 is fixedly connected to the output end of the second servo motor 3041, and multiple bevel gears 301 are fixedly connected at equal intervals to the outer wall of the transmission rod 3042. 43. A bevel gear 3044 is installed on the rear side of the outer wall of multiple bevel gears 3043. The rear side of the outer wall of bevel gear 3043 meshes with the bottom of the outer wall of bevel gear 3044. A threaded rod 3045 is fixedly connected to the rear side of the outer wall of bevel gear 3044. The upper and lower ends of the threaded frame 302 are threadedly connected to the outer wall of the threaded rod 3045. A protective frame 3046 is installed on the outer wall of bevel gear 3043. The rear side of the outer wall of the protective frame 3046 is fixedly connected to the front side of the outer wall of the hopper 1. The bottom of the outer wall of servo motor 3041 is fixedly connected to the top of the outer wall of the protective frame 3046.

[0035] Specifically, when the servo motor 3041 is turned on, its output end can drive the transmission rod 3042 to rotate, which in turn drives the multiple bevel gears 3043 welded to the outer wall of the transmission rod 3042 to rotate synchronously. Through the meshing of the bevel gears 3043 and the bevel gear 3044, the bevel gear 3044 drives the threaded rod 3045 welded to its outer side to rotate. When the threaded rod 3045 rotates, due to the rotation restriction of the threaded frame 302 by the two threaded rods 3045, the threaded frame 302 will drive the cleaning brush 301 to only move along the threaded rods 3045. The axial movement enables the cleaning of the heat sink 5. The cooling fan 303 on the inner wall of the threaded bracket 302 operates, improving heat dissipation efficiency while blowing away dust, further enhancing the cleaning effect. The protective bracket 3046 surrounds the outer side of the first bevel gear 3043 and the second bevel gear 3044, protecting them from external impacts and moisture, ensuring stable meshing transmission between the first bevel gear 3043 and the second bevel gear 3044, and ensuring coordinated operation of all components of the cleaning mechanism 3, effectively completing the cleaning of the heat sink 5.

[0036] Reference Figure 2 , Figure 3 and Figure 4 A heat dissipation plate 5 is fixedly connected to the lower right end of the hopper 1. The heat dissipation plate 5 is installed on the right end of the outer wall of the cleaning mechanism 3.

[0037] Specifically, a heat dissipation plate 5 is fixedly connected to the lower right end of the hopper 1. This fixing method ensures that the heat dissipation plate 5 can be stably attached to the hopper 1 and continuously play a heat dissipation role. The heat dissipation plate 5 is installed on the right end of the outer wall of the cleaning mechanism 3, so that the cleaning brush 301 in the cleaning mechanism 3 can directly act on the surface of the heat dissipation plate 5 during the movement, which is convenient for cleaning the heat dissipation plate 5 and ensures that the heat dissipation effect of the heat dissipation plate 5 is not affected by impurities.

[0038] Working principle: When the servo motor 2041 is turned on, its power is transmitted through the transmission shaft 2042 to multiple gears 2043 welded to its outer wall, causing them to rotate synchronously. Through the meshing of the gears 2043 and the rack 202, the rack 202 drives the baffle 201 welded to the outside to slide inside the right end of the hopper 1. When the baffle 201 moves, it changes its relative position with the discharge port 4, thereby controlling the discharge area of ​​the discharge port 4. When the baffle 201 completely blocks the discharge port 4, the discharge stops. When the baffle 201 is partially removed, the discharge port 4 is partially exposed, and the material begins to be discharged. The size of the exposed area determines the discharge speed. The protective cover 203 protects the rack 202 from damage by the material in the hopper 1. The limit plate 2044 ensures the stable rotation of the drive shaft 2042. The support frame 2045 is welded to the bottom of the servo motor 2041 and welded to the hopper 1 to support the servo motor 2041, ensuring the stable operation of the entire mechanism and effectively controlling the discharge speed and the start and stop of discharge.

[0039] When the servo motor 3041 is turned on, its output end can drive the transmission rod 3042 to rotate, which in turn drives the multiple bevel gears 3043 welded to the outer wall of the transmission rod 3042 to rotate synchronously. Through the meshing of bevel gears 3043 and bevel gear 3044, bevel gear 3044 drives the threaded rod 3045 welded to its outer side to rotate. When the threaded rod 3045 rotates, due to the rotation restriction of the threaded frame 302 by the two threaded rods 3045, the threaded frame 302 will drive the cleaning brush 301 to move only along the axial direction of the threaded rods 3045, thereby cleaning the heat sink 5. The cooling fan 303 on the inner wall of the threaded frame 302 works, which improves the heat dissipation efficiency and blows away dust, further improving the cleaning effect. The protective frame 3046 protects the bevel gears 3043 and 3044, preventing them from being hit and moisture, ensuring stable power transmission, and ensuring the effective operation of the cleaning mechanism 3.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
