For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] See also Figures 1 to 3 As shown, a three-head screw vertical conveying device according to the present application is schematically shown, which is mainly used in a screw ship unloader to convey materials vertically upward.

[0041] According to an embodiment of the present application, a three-head spiral vertical conveying device is provided, which includes a spiral body 100, a spiral outer tube 200 and a driving mechanism 400.

[0042] Among them, Figure 3 As shown, the spiral body 100 includes a spiral shaft 110 and three spiral blades 120. The spiral shaft 110 is arranged in a vertical direction. The three spiral blades 120 are arranged on the spiral shaft 110 at intervals. The spiral directions of the three spiral blades 120 are the same, and the three spiral blades 120 extend from the lower end of the spiral shaft 110 to the upper end of the spiral shaft 110 respectively. The spiral outer tube 200 is sleeved outside the spiral body 100, and a conveying channel 300 is formed between the spiral outer tube 200 and the spiral body 100. The driving mechanism 400 is connected to the spiral shaft 110, and the driving mechanism 400 is used to drive the spiral shaft 110 to rotate so that the material in the conveying channel 300 is conveyed upward.

[0043] It should be noted that if there are too few spiral blades 120, the filling rate of the spiral conveyor will be low, and the productivity will be low; if there are too many spiral blades 120, the distance between two adjacent spiral blades 120 will be small, and it will be easy to cause problems such as blockage.

[0044] During use, the driving mechanism 400 drives the spiral body 100 to rotate, and the three spiral blades 120 rotate together with the spiral shaft 110. When the material enters the conveying channel 300 between the spiral outer tube 200 and the spiral body 100, the material in the conveying channel 300 is conveyed upward under the action of the three spiral blades 120. The vertical conveying device of the present application adopts a three-head spiral structure, which not only increases the filling rate of the spiral conveying and improves the production efficiency, but also is not easy to cause problems such as material blocking, has high safety and reliability, and can meet increasingly high demands.

[0045] If the outer diameter of the spiral blade 120, the pitch of the spiral blade 120, the rotation speed of the spiral shaft 110, and the distance between two adjacent spiral blades 120 are too large or too small, they will have an adverse effect on the device. Figure 3 As shown, the three spiral blades 120 are evenly distributed in the circumferential direction of the cross section perpendicular to the spiral shaft 110, the outer diameter of each spiral blade 120 is d, d is 940~1040mm, the pitch of each spiral blade 120 is h, h is 900~1000mm, and the output speed of the driving mechanism 400 is 260~300r / min, that is, the speed of the spiral shaft 110 is 260~300r / min.

[0046] That is to say, the diameter of the spiral body 100 is 940-1040 mm, the gaps between two adjacent spiral blades 120 of the three spiral blades 120 are equal, and the pitches of the three spiral blades 120 are equal, which fully improves the filling rate of the spiral conveyor without blocking. Therefore, the productivity of the equipment can reach 2000t / h-2500t / h, and it can also ensure that there will be no problems such as blocking, which is safer, more stable and reliable.

[0047] In some embodiments, the driving mechanism 400 is located above the spiral body 100, and the driving mechanism 400 includes a motor 410 and a gearbox 420, the motor 410 is connected to the gearbox 420, and the output end of the gearbox 420 is connected to the spiral shaft 110. In this way, not only can the spiral body 100 be driven to rotate better, but also the speed of the spiral body 100 can be adjusted, which is more stable and reliable.

[0048] Furthermore, there are two motors 410, and both motors 410 are connected to the gearbox 420. That is to say, the synchronous driving of the two motors 410 facilitates the movement of the box, and the load is distributed to the two motors 410, so that the operation is more convenient, and the screw body 100 is better driven to rotate, and the safety and reliability are higher.

[0049] Those skilled in the art can understand that the motor 410 of the present application can be a servo motor, a stepper motor, a hydraulic motor, etc., and there can be multiple motors 410 of the present application.

[0050] In some embodiments, the output end of the gearbox 420 is connected to the screw shaft 110 via a universal coupling 430. Thus, the operation is more convenient and quick, and the axial vibration and impact can be absorbed, the impact and vibration force on the equipment can be reduced, and the parts of the equipment can be protected.

[0051] In some embodiments, the three-head screw vertical conveying device of the present application further includes a feeding mechanism 500. The feeding mechanism 500 is located at the lower end of the screw body 100, and the feeding mechanism 500 is used to feed the materials in the cabin into the conveying channel 300.

[0052] It should be noted that the feeder is a feeding device in the prior art and will not be described in detail herein. For example, the feeder is driven by a driving assembly 700 , and the driving assembly 700 may refer to the driving mechanism 400 described above.

[0053] That is, when unloading, the feeder is inserted into the material in the cabin, the drive assembly 700 drives the feeder to work, so as to feed the material into the conveying channel 300 of the present application, and then the drive mechanism 400 drives the screw body 100 to rotate, and under the action of the three spiral blades 120, the material in the conveying channel 300 is conveyed upward. In this way, the material is better fed into the conveying channel 300.

[0054] In some embodiments, the three-head spiral vertical conveying device of the present application further includes a supporting mechanism 600 , which is connected to the spiral outer tube 200 .

[0055] That is to say, the support mechanism 600 is fixedly arranged and connected to the spiral outer tube 200, so as to stably support the spiral outer tube 200 and the spiral body 100, thereby improving the lateral stiffness of the spiral body 100 and the spiral outer tube 200, avoiding the risk of shaft breakage during high-speed rotation of the spiral body 100, etc., ensuring better material transportation, etc., with higher safety and reliability.

[0056] Furthermore, the support mechanism 600 includes a fixing frame 610. The fixing frame 610 is located on one side of the spiral outer tube 200, and a clamp assembly 620 connected to the spiral outer tube 200 is provided on the fixing frame 610. Thus, the spiral outer tube 200 is secured by the clamp assembly 620, the operation is more convenient and quick, and the structure is more stable.

[0057] Furthermore, there are multiple clamp assemblies 620, and the multiple clamp assemblies 620 are arranged in sequence along the axial direction of the spiral outer tube 200. Therefore, the spiral outer tube 200 is tightly clamped by the multiple clamp assemblies 620, so that the spiral outer tube 200 can be supported more stably.

[0058] Furthermore, a plurality of clamp assemblies 620 are arranged in unequal intervals in the axial direction of the spiral outer tube 200. Figure 1 As shown, taking five clamp assemblies 620 as an example, the intervals between the five clamp assemblies 620 are t1, t2, t3 and t4 respectively.

[0059] It should be noted that t1, t2, t3 and t4 may not be equal; or t1 and t3 may be equal, t2 and t4 may be equal, and t1 and t2 may not be equal.

[0060] That is to say, by arranging the five clamp assemblies 620 at unequal intervals, the natural frequency of the spiral body 100 is inconsistent in the vertical direction, thereby avoiding resonance during the high-speed rotation of the spiral body 100, reducing the amplitude, and improving safety, stability and reliability, thereby increasing the service life of the equipment.

[0061] According to an embodiment of the present application, a screw ship unloader is provided, comprising the above three-head screw vertical conveying device. It should be noted that the horizontal screw conveyor and other devices of the screw ship unloader are common mechanisms in the prior art and will not be described in detail here.

[0062] Therefore, the screw ship unloader of the present application adopts the above-mentioned three-head screw vertical conveying device, which not only increases the filling rate of the screw conveyor and improves the production efficiency, but also is not easy to cause problems such as blockage. It is easy to operate and has high safety, stability and reliability. The productivity can reach 2000t / h-2500t / h, which can meet increasingly higher demands.

[0063] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0064] The above are only some embodiments of the present application, which are only used to illustrate the technical solution of the present application, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present application, it is possible to improve or replace it according to the above description, and all these improvements and replacements should belong to the protection scope of the claims attached to the present application.
