Technical Field

[0001] This utility model relates to the technical field of unloading mechanisms, and in particular to an unloading mechanism for organic chemical raw materials. Background Technology

[0002] Natural organic chemical raw materials come from nature, while artificially synthesized organic chemical raw materials are prepared in the laboratory through synthetic reactions. Organic chemical raw materials have a wide range of applications; they can be used in organic chemical synthesis as well as biosynthesis. They are widely used in various fields, including but not limited to: 1. Building materials (such as mortar, steel bars, tiles, glass, and plastics); 2. Transportation vehicles (fuels used in aircraft, ships, and automobiles are byproducts of petroleum refining); 3. The pharmaceutical industry; 4. Daily necessities. With the development of the chemical industry, the loading and unloading of chemical products requires specialized equipment to improve efficiency and safety. Existing technology publication CN2 16234980U discloses a chemical product unloading device, including a base plate with three casters fixedly connected to its bottom. Support columns are fixedly connected to both sides of the top of the base plate, and a rotating shaft is fixedly connected to the top of each support column. A conveyor belt is rotatably connected to each support column via the rotating shaft. However, its bottom support area is small, and it needs to be moved by a conveyor belt, requiring multiple workers to cooperate, making it inconvenient to use, prone to slipping, and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an organic chemical raw material unloading mechanism that is easy to adjust in height and angle, suitable for transport vehicles of different heights, improves the convenience of use, and enhances practicality.

[0004] This utility model discloses an organic chemical raw material unloading mechanism, comprising a base plate, multiple support legs, multiple casters, a belt conveyor, a lifting assembly, an angle adjustment assembly, and a fixing assembly. Support legs are fixedly installed at the four corners of the base plate, and casters are installed at the bottom of the support legs. The belt conveyor is mounted on top of the base plate via the lifting assembly. An angle adjustment assembly is installed between the lifting assembly and the belt conveyor. Fixing assemblies are installed at both ends of the base plate. The support legs and casters enable the base plate to move, increasing the support area and ensuring stability during use, while also facilitating movement. The fixing assemblies can fix and limit the left and right sides of the base plate to prevent slippage and potential safety hazards during use. The lifting assembly can adjust the height of the belt conveyor, making it suitable for transport vehicles of different heights. The angle adjustment assembly can adjust the tilt angle of the belt conveyor, improving ease of use and practicality.

[0005] Preferably, the lifting assembly includes two columns, two threaded columns, two gearboxes, two dual-output motors, two drive shafts, two lifting blocks, and guide components. The two columns are fixedly installed at the front and rear ends of the top center of the base plate, respectively. A lifting groove is opened in the middle of the column, and a drive cavity is opened inside the base plate. The two threaded columns are rotatably installed in the lifting groove, and the bottom of the threaded columns extends into the drive cavity and connects to the output end of the gearbox. The two gearboxes are located at the front and rear ends of the drive cavity, respectively. The dual-output motors are installed in the middle of the drive cavity, and the front and rear output ends of the dual-output motors are connected to the input end of the gearbox through the drive shaft. The two lifting blocks are screwed onto the outer wall of the threaded columns, and the belt conveyor is located between the two lifting blocks. When the dual-output motors are started, they drive the two threaded columns to rotate through the drive shafts and gearboxes, causing the lifting blocks to move within the lifting grooves of the columns. This allows for adjustment of the height of the belt conveyor, making it suitable for transport vehicles of different heights, increasing its application range, and improving its practicality.

[0006] Preferably, the guiding component includes two sets of guide sliders and two sets of limiting sliders. Guide grooves are symmetrically provided on the left and right sides of the column about the lifting groove. The two guide sliders are slidably installed in the lifting groove and are respectively connected to the left and right side walls of the lifting block. Limiting guide grooves are symmetrically provided in the front and back of the guide groove. Limiting sliders are fixedly installed at the front and back ends of the guide sliders and are slidably installed in the limiting guide grooves. When the lifting block moves, it drives the guide sliders to move in the guide grooves. At the same time, the guide sliders drive the limiting sliders to slide in the limiting guide grooves, which can ensure the stability of the lifting block when it moves, avoid shaking, and increase the connection strength.

[0007] Preferably, the angle adjustment assembly includes two rotating shafts, two sets of mounting plates, two sets of hydraulic cylinders, two sets of support rods, and two sets of connectors. The front and rear end sidewalls of the belt conveyor are rotatably connected to the lifting block via the rotating shafts. The mounting plate is fixedly connected to the outer wall of the guide slider, and the hydraulic cylinder is rotatably mounted on the lower end of the mounting plate. Support rods are slidably mounted on the left and right sides of the front and rear end sidewalls of the belt conveyor, and connectors are rotatably mounted on the support rods. The connectors are fixedly connected to the extension and retraction ends of the hydraulic cylinders. When it is necessary to adjust the angle of the belt conveyor, the hydraulic cylinder on the same side is retracted, while the hydraulic cylinder on the other side extends. This allows the belt conveyor to tilt in the retraction direction via the rotating shaft on the lifting block. Similarly, it can be adjusted to the other side. By controlling the retraction and extension lengths of the hydraulic cylinders, the angle of the belt conveyor can be controlled, improving the convenience of use.

[0008] Preferably, the fixing assembly includes two sets of second hydraulic cylinders, two sets of rotating seats, two sets of second rotating seats, and two push plates. The two sets of second hydraulic cylinders are rotatably mounted on the front and rear sides of the left and right end sidewalls of the base plate via the rotating seats. The front and rear ends of the push plates are rotatably mounted on the lower end sidewalls of the outriggers via the second rotating seats. The telescopic ends of the second hydraulic cylinders are movably connected to the top of the push plates. After the base plate is moved to the use position, the two sets of second hydraulic cylinders are activated to extend, causing the push plates to rotate and extend on the second rotating seats, moving towards the ground and limiting the left and right sides of the equipment.

[0009] Preferably, it also includes multiple support columns and two support blocks. Multiple support columns are fixedly installed at the bottom of the push plate, and support blocks are connected to the bottom of the support columns. Friction strips are provided at the bottom of the support blocks. When the push plate rotates downward, it pushes the support blocks to move through the support columns, so that the support blocks contact the ground, increase the friction with the ground, prevent movement during use, and improve stability and safety.

[0010] Preferably, it also includes two sets of diagonal braces and two handles. The diagonal braces are bolted to the left and right ends of the front and rear side walls of the base plate. The other end of the diagonal braces is connected to the upper outer wall of the column by bolts. The handles are installed on the outer wall of the column. The diagonal braces can support the column, increase the structural strength, and ensure the service life. The handles make it easier to push the equipment and improve convenience.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, support legs 2 are fixedly installed at the four corners of the bottom of the base plate 1. Casters 3 are installed at the bottom of the support legs 2. Two uprights 5 are fixedly installed at the front and rear ends of the top center of the base plate 1, respectively. A lifting groove is formed in the middle of the uprights 5. A drive cavity is formed inside the base plate 1. Two threaded columns 6 are rotatably installed in the lifting groove, with the bottom of the threaded columns 6 extending into the drive cavity and connecting to the output end of the gearbox 7. The two gearboxes 7 are located at the front and rear ends of the drive cavity, respectively. A dual-output motor 8 is installed in the middle of the drive cavity. The output ends of the dual-output motor 8 on both sides are connected to the input of the gearbox 7 via a drive shaft 9. The two lifting blocks 10 are screwed onto the outer wall of the threaded column 6. The belt conveyor 4 is located between the two lifting blocks 10. The two sets of second hydraulic cylinders 18 are rotatably installed on the front and rear sides of the left and right side walls of the base plate 1 through the rotating seat 19. The front and rear ends of the push plate 21 are rotatably installed on the lower side wall of the support leg 2 through the second rotating seat 20. The telescopic end of the second hydraulic cylinder 18 is movably connected to the top of the push plate 21. Multiple support columns 22 are fixedly installed at the bottom of the push plate 21. Support blocks 23 are connected to the bottom of the support columns 22. Friction strips are provided at the bottom of the support blocks 23.

[0021] After the base plate 1 is moved to the usage position, the two sets of second hydraulic cylinders 18 are activated to extend, causing the push plate 21 to rotate and extend on the second rotating seat 20, moving towards the ground. When the push plate 21 rotates downward, it pushes the support block 23 to move through the support column 22, so that the support block 23 contacts the ground, increasing the friction with the ground, preventing movement during use, and improving stability and safety. The dual-output motor 8 is activated to drive the two threaded columns 6 to rotate through the transmission shaft 9 and the gearbox 7, so that the lifting block 10 moves in the lifting slide of the column 5, thereby adjusting the height of the belt conveyor 4, which is suitable for transport vehicles of different heights, increasing the range of applications and improving practicality.

[0022] Example 2

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, based on embodiment 1, the column 5 is further provided with symmetrical guide grooves on the left and right sides about the lifting groove. Two guide sliders 12 are slidably installed in the lifting groove and are respectively connected to the left and right side walls of the lifting block 10. Limiting guide grooves are symmetrically opened in the front and back of the guide groove. Limiting sliders 13 are fixedly installed at the front and back ends of the guide slider 12. The limiting sliders 13 are slidably installed in the limiting guide grooves. The front and back side walls of the belt conveyor 4 are rotatably connected to the lifting block 10 through the rotating shaft 11. The outer wall of the guide slider 12 is fixedly connected with the mounting plate 14. The lower end of the mounting plate 14 is rotatably installed with the hydraulic cylinder 15. The left and right sides of the front and back side walls of the belt conveyor 4 are slidably installed with support rods 16. The support rods 16 are rotatably installed with connectors 17. The connectors 17 are fixedly connected to the telescopic end of the hydraulic cylinder 15. The left and right sides of the front and back side walls of the base plate 1 are bolted with diagonal braces 24. The other end of the diagonal braces 24 is bolted to the upper outer wall of the column 5. The handle 25 is installed on the outer wall of the column 5.

[0024] When the lifting block 10 moves, it drives the guide slider 12 to move within the guide groove. At the same time, the guide slider 12 drives the limit slider 13 to slide within the limit guide groove, which can ensure the stability of the lifting block 10 during movement, avoid swaying, and increase the connection strength. When it is necessary to adjust the angle of the belt conveyor 4, the hydraulic cylinder 15 on the same side is activated to retract, while the hydraulic cylinder 15 on the other side extends. This allows the belt conveyor 4 to tilt in the retraction direction on the lifting block 10 via the rotating shaft 11. Similarly, it can be adjusted to the other side. By controlling the retraction and extension length of the hydraulic cylinder 15, the angle of the belt conveyor 4 can be controlled, improving the convenience of use. The diagonal brace 24 can support the column 5, increasing the structural strength and ensuring service life. The handle 25 makes it easy to push the equipment, improving convenience.

[0025] like Figures 1 to 5As shown, this utility model discloses an organic chemical raw material unloading mechanism. During operation, the device is pushed by the lever 25, causing the moving wheel 3 to move the device to the usage position. After moving to the usage position, two sets of second hydraulic cylinders 18 are activated to extend, causing the push plate 21 to rotate and extend on the second rotating seat 20, moving towards the ground. When the push plate 21 rotates downward, it pushes the support block 23 to move through the support column 22, making the support block 23 contact the ground, increasing the friction with the ground and preventing movement during use. The dual-output motor 8 is activated to drive two threaded columns 6 to rotate through the transmission shaft 9 and the gearbox 7, causing the lifting block 10 to move in the lifting groove of the column 5, thereby adjusting the height of the belt conveyor 4. The hydraulic cylinder 15 on the same side is activated to retract, while the hydraulic cylinder 15 on the other side extends, allowing the belt conveyor 4 to tilt in the retraction direction on the lifting block 10 through the rotating shaft 11. After docking with the transport vehicle, the material can be unloaded through the belt conveyor 4.

[0026] The belt conveyor 4, gearbox 7, and dual-output motor 8 of the organic chemical raw material unloading mechanism of this utility model are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
