Description

Technical Field

[0001] This application relates to the field of conveyor technology, specifically to a dual-shaft conveyor. Background Technology

[0002] A twin-shaft conveyor, also known as a twin-shaft screw conveyor or twin-shaft screw feeder, is a device used for material conveying. A twin-shaft conveyor mainly consists of two screws rotating in opposite directions. As the screws rotate, the material can move along the axial direction of the screws, and the two screws also achieve a mixing effect on the material.

[0003] Chinese patent CN221115642U discloses a novel screw conveyor, specifically comprising a housing, a rotating shaft within the housing, helical blades on the rotating shaft, and a transmission mechanism located outside the housing and connected to the rotating shaft. The key technical features are: two rotating shafts of equal diameter arranged parallel to each other at equal heights within the housing; helical blades of identical size arranged symmetrically on both shafts; corresponding wave crests and troughs on the two helical blades; and synchronous rotation of the two rotating shafts in opposite directions. This patent solves the problem of material entanglement on the shaft in existing screw conveyors, avoids obstructed discharge, minimizes frequent downtime for maintenance, extends operating time, and improves production efficiency.

[0004] However, in the aforementioned patent, the transmission mechanism is exposed, which makes it easy for external debris to adhere to the transmission mechanism. Cleaning usually requires stopping the machine, affecting the continuous operation of the conveyor. Utility Model Content

[0005] In order to overcome the problem that the transmission mechanism of the conveyor cannot be cleaned online in the prior art, this application provides a dual-shaft conveyor.

[0006] This application adopts the following technical solution: a dual-shaft conveyor, including a base, on which a driving component, a transmission component, and a housing are provided. A pair of shafts are inserted inside the housing, and helical blades are sleeved on the shafts. The transmission component includes a first transmission shaft and a second transmission shaft. The first transmission shaft is connected to one of the shafts, and the second transmission shaft is connected to the other shaft, both via couplings. The end of the first transmission shaft is provided with a driving gear, and the end of the second transmission shaft is provided with a driven gear that meshes with the driving gear. A cover is provided above the driving gear and the driven gear, and a support plate for fixing the cover is provided on the base.

[0007] The support plate is provided with a nozzle on the side facing the driven gear, and the nozzle can spray cleaning fluid or lubricating oil onto the driven gear.

[0008] Optionally, the transmission component is disposed between the drive component and the shaft, and the power generated by the drive component is transmitted to the shaft through the transmission component. The drive component is an electric motor.

[0009] Optionally, the base is further provided with a liquid storage tank, and the liquid storage tank is provided with a partition, which divides the internal space of the liquid storage tank into a first chamber and a second chamber. The first chamber is used to store cleaning fluid, and the second chamber is used to store lubricating oil.

[0010] The first chamber is provided with a first pipe for delivering cleaning fluid to the nozzle, and the second chamber is provided with a second pipe for delivering lubricating oil to the nozzle.

[0011] Optionally, a first pump body is provided at the bottom inner side of the first chamber, and the liquid outlet of the first pump body is connected to the first pipeline. A second pump body is provided at the bottom inner side of the second chamber, and the liquid outlet of the second pump body is connected to the second pipeline.

[0012] Optionally, the outer wall of the liquid storage tank is provided with two connectors, one of which communicates with the first chamber and is used to replenish the cleaning fluid, and the other connector communicates with the second chamber and is used to replenish the lubricating oil.

[0013] Optionally, the top of the liquid storage tank is provided with a switch base, which is provided with a first switch for controlling the opening and closing of the first pump body and a second switch for controlling the opening and closing of the second pump body.

[0014] Optionally, the height of the first switch is less than the height of the second switch, the first switch is a push-button switch, and the second switch is a rotary switch.

[0015] Compared with the prior art, this application can reduce the adhesion of debris to the drive gear or driven gear by setting the cover, and when there is a lot of debris, the first pump body delivers cleaning fluid to the nozzle, thereby completing the cleaning of the drive gear and driven gear without stopping the machine, improving the continuity of the conveyor operation.

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-4 As shown, the dual-shaft conveyor includes a base 1, on which a drive component 2, a transmission component 3, and a housing 4 are provided. The drive component 2 is an electric motor. A pair of shafts 5 are installed inside the housing 4. The transmission component 3 is located between the drive component 2 and the shafts 5. The power generated by the drive component 2 is transmitted to the shafts 5 through the transmission component 3. A spiral blade 50 is sleeved on the shaft 5. The transmission component 3 includes a first transmission shaft 31 and a second transmission shaft 32. The first transmission shaft 31 is connected to one shaft 5, and the second transmission shaft 32 is connected to the other shaft 5 through a coupling 33. The end of the first transmission shaft 31 is provided with a drive gear 34, and the end of the second transmission shaft 32 is provided with a driven gear 35 that meshes with the drive gear 34.

[0023] The electric motor can drive the first transmission shaft 31 to rotate, and the driving gear 34 can rotate synchronously with the first transmission shaft 31. When the driving gear 34 rotates, the driven gear 35 meshing with the driving gear 34 will also rotate and drive the second transmission shaft 32 to rotate. When the first transmission shaft 31 and the second transmission shaft 32 rotate at the same time, the two shafts 5 will also rotate in opposite directions. In this way, the spiral blades 50 welded on the shafts 5 will rotate, thereby realizing the conveying of materials.

[0024] A cover 6 is provided above the driving gear 34 and the driven gear 35, and a support plate 10 for fixing the cover 6 is provided on the base 1; a nozzle 7 is provided on the side of the support plate 10 facing the driven gear 35, and the nozzle 7 can spray cleaning fluid or lubricating oil onto the driven gear 35.

[0025] The cover 6 is fixed in a fixed state under the support plate 10. The semi-enclosed cover 6 protects the meshing drive gear 34 and driven gear 35, reducing contamination from debris. After prolonged use and accumulation of debris, cleaning fluid can be sprayed onto the driven gear 35 through the nozzle 7. As the driven gear 35 rotates, the cleaning fluid simultaneously cleans both the driven gear 35 and the drive gear 34, ensuring their reliable operation. Furthermore, the cleaning operation can be performed online without stopping the machine, ensuring continuous conveyor operation. After cleaning and once the drive gear 34 and driven gear 35 are dry, lubricating oil can be sprayed onto them through the nozzle 7 to improve lubrication and extend their service life.

[0026] The base 1 is also provided with a liquid storage tank 8. The liquid storage tank 8 is provided with a partition 81, which divides the internal space of the liquid storage tank 8 into a first chamber 82 and a second chamber 83. The first chamber 82 is used to store cleaning fluid, and the second chamber 83 is used to store lubricating oil. The first chamber 82 is provided with a first pipe 84 for delivering cleaning fluid to the nozzle 7, and the second chamber 83 is provided with a second pipe 85 for delivering lubricating oil to the nozzle 7.

[0027] After the partition 81 is installed, the cleaning fluid and lubricating oil can be separated, ensuring that the cleaning fluid can be reliably sprayed when cleaning is required, and the lubricating oil can be reliably sprayed when lubrication is required.

[0028] The bottom inner side of the first chamber 82 is provided with a first pump body 86, and the liquid outlet of the first pump body 86 is connected to the first pipe 84. The bottom inner side of the second chamber 83 is provided with a second pump body 87, and the liquid outlet of the second pump body 87 is connected to the second pipe 85.

[0029] When cleaning is required, the first pump body 86 is activated, pumping the cleaning fluid into the first pipe 84, which then supplies it to the nozzle 7, and finally sprays the cleaning fluid onto the driven gear 35 through the nozzle 7. When enhanced lubrication is required, the second pump body 87 is activated, pumping lubricating oil into the second pipe 85, which then supplies it to the nozzle 7, and finally sprays the cleaning fluid onto the driven gear 35 through the nozzle 7.

[0030] Two connectors 88 are provided on the outer wall of the reservoir 8. One connector 88 communicates with the first chamber 82 and is used to replenish the cleaning fluid, while the other connector 88 communicates with the second chamber 83 and is used to replenish the lubricating oil. Both connectors 88 are located at the top of the reservoir 8, allowing for individual replenishment of either the cleaning fluid or the lubricating oil. Furthermore, a level sensor can be installed in both the first chamber 82 and the second chamber 83 to facilitate timely replenishment of the cleaning fluid or lubricating oil, and to ensure that the inlet end of the first pump body 86 is always below the level of the cleaning fluid and the inlet end of the second pump body 87 is always below the level of the lubricating oil. This ensures reliable cleaning and lubrication while preventing the first pump body 86 or the second pump body 87 from burning out.

[0031] The top of the liquid storage tank 8 is provided with a switch base 89, on which a first switch 891 for controlling the opening and closing of the first pump body 86 and a second switch 892 for controlling the opening and closing of the second pump body 87 are provided. The height of the first switch 891 is less than the height of the second switch 892. The first switch 891 is a push-button switch and the second switch 892 is a rotary switch.

[0032] The first switch 891 and the second switch 892 are located on the outside of the liquid storage tank 8 for easy operation. Since the first switch 891 and the second switch 892 are of different types, blind operation can be achieved to prevent operational errors.

[0033] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
