Description

Technical Field

[0001] This utility model belongs to the technical field of screw conveyors, and particularly relates to a high-strength screw conveyor. Background Technology

[0002] A screw conveyor is a device that uses the driving force of a screw thread to propel materials. Screw conveyors are used because of their high pushing force, making them suitable for conveying various materials. Due to the screw thread's driving force, materials are fed smoothly during the pushing process, especially when pushed upwards. Therefore, in current technology, screw conveyors are mostly used to push materials from lower to higher locations.

[0003] The main structure of the screw conveyor disclosed in the prior art includes a screw barrel and an auger installed inside the screw barrel. The auger is driven to rotate by a motor, and the material is continuously moved under the push of the auger in the screw structure during rotation. In order to achieve the conveying of materials from low to high, the prior art uses a bracket installed at the bottom of the screw barrel to raise it. However, this method has the following drawbacks: First, this method occupies a lot of workshop space, making it difficult to disassemble the bracket when not in use, and because the screw barrel is raised, the disassembly process has a very high risk factor. Second, in actual operation, it is often necessary to feed materials to different heights, such as trucks of different tonnages, which have different heights. Therefore, the height of the screw barrel needs to be adjustable, but the fixed bracket method makes it difficult to adjust the height of the screw barrel. As a result, in actual operation, the discharge end of the screw barrel (located at the top) is either too high relative to the target feeding height, resulting in an excessively long material flow during the feeding process, which easily generates a lot of dust. Or the discharge end of the screw barrel does not reach the target feeding height, requiring the screw to be raised during actual operation, and if the height difference is too large, it is also difficult to raise it.

[0004] Therefore, in actual work, the application of screw conveyors, which have very low mobility and flexibility, is very limited. Utility Model Content

[0005] Based on the above background, the purpose of this utility model is to provide a high-strength spiral conveyor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed screw conveyor includes a screw conveyor mechanism, the screw conveyor mechanism including a conveyor barrel;

[0008] The height screw conveyor also includes a hydraulic cylinder pulling mechanism for adjusting the height of the screw conveyor mechanism;

[0009] The hydraulic cylinder pulling mechanism includes a long pull arm hinged to the upper end of the conveyor drum, and a pulling hydraulic cylinder is fixedly connected to the lower end of the long pull arm.

[0010] The hydraulic cylinder pulling mechanism also includes a hinged base, on which the lower end of the conveyor barrel is hinged;

[0011] The bottom of the hinged base is fixedly connected to a bottom bracket, and tension arm structures are installed on both sides of the bottom bracket, which provide support when opened.

[0012] Preferably, the screw conveyor mechanism further includes a pusher auger rotatably connected inside the conveyor barrel;

[0013] The lower end of the conveyor drum is equipped with a motor that drives the auger to rotate.

[0014] The bottom of the upper end of the conveyor drum is connected to a discharge pipe for discharging materials.

[0015] Preferably, the conveyor barrel is rectangular in shape, and a top cover plate is installed on the top of the conveyor barrel;

[0016] The bottom of the top cover plate is connected to a feeding hopper. Material is fed from the feeding hopper into the conveyor cylinder. The rotating auger pushes the material from a low position to a high position before discharging it.

[0017] Preferably, hydraulic cylinder pulling mechanisms are hinged to the left and right sides of the conveyor barrel.

[0018] Preferably, the upper end of the long pull arm is fixedly connected to a hinged upper seat, and the hinged upper seat is hinged to a pin fixedly connected to the side wall of the conveyor drum.

[0019] Preferably, the traction cylinder is a multi-stage telescopic cylinder, and the pushing end of the multi-stage telescopic cylinder is fixed to the bottom of the long pull arm through a connecting flange.

[0020] Preferably, the bottom of the cylinder of the multi-stage telescopic cylinder is fixedly connected to a tongue seat, and a connecting shaft is fixedly connected between the tongue seats;

[0021] The bottom bracket is connected to a fixed bracket at its top height, and a hinged lower seat is fixedly connected to the top of the fixed bracket. The hinged lower seat is hinged to the connecting shaft.

[0022] Preferably, the tension arm structure includes a tension arm rod;

[0023] The inner end of the boom is hinged to the side wall of the bottom support.

[0024] Preferably, the inner end of the boom arm is provided with a hinge slot, and a hinge boss is fixedly connected to the side wall of the bottom bracket, which is hinged in the hinge slot. The top and bottom of the hinge boss are respectively hinged to the hinge slot by pins.

[0025] This utility model has the following beneficial effects:

[0026] 1. During operation, when it is necessary to adjust the height of the conveyor barrel discharge end, the multi-stage telescopic cylinder in the hydraulic cylinder pulling mechanism synchronously pulls the conveyor barrel (during the pulling process, due to the hinge of the multi-stage telescopic cylinder, the multi-stage telescopic cylinder flips). The heavy conveyor barrel gradually increases in height under the pull. Since the multi-stage telescopic cylinder is a conventional multi-stage telescopic cylinder disclosed in the prior art, it can have multiple telescopic lengths, realizing the adjustable lifting height of the conveyor barrel during operation, and realizing lifting at multiple height positions.

[0027] After being lifted to the target height, the operator feeds the material into the feeding hopper via a horizontal conveyor. The material is then discharged from the height by the conveyor cylinder.

[0028] This method greatly improves the flexibility of the screw conveyor, allowing the conveyor drum to be raised in an adjustable manner for feeding operations as needed. Furthermore, the entire process is fully automated, significantly increasing operational efficiency.

[0029] 2. During operation, adjust the boom's opening position according to the rise angle of the conveyor drum. Because the boom has a larger support surface when open, it maintains the stability of the conveyor drum in the raised state. If the rise angle of the conveyor drum increases, increase the boom's opening angle to match the increase; conversely, if the conveyor drum descends, decrease the boom's opening angle to match the descent.

[0030] Increasing or decreasing the opening range of the boom is intended to coordinate with the upward and downward movement of the conveyor barrel, ensuring that the conveyor barrel can be adequately and stably supported. Attached Figure Description

[0041] Example 1

[0042] like Figures 1-5As shown, a high-strength screw conveyor includes a screw conveyor mechanism 1, which has the same structure as existing screw conveyors. The screw conveyor mechanism 1 includes a conveyor barrel 11. The screw conveyor mechanism 1 also includes a pusher auger 15 rotatably connected inside the conveyor barrel 11. A motor 13 for driving the pusher auger 15 to rotate is installed at the lower end of the conveyor barrel 11. Similar to existing methods, the output shaft of the motor 13 is fixedly mounted on the shaft of the pusher auger 15 (the pusher auger 15 includes a shaft and helical pusher blades welded and fixed to the shaft). Similar to existing structures, the shaft of the pusher auger 15 is rotatably connected to the upper and lower ends of the conveyor barrel 11.

[0043] Meanwhile, the bottom of the upper end of the conveyor barrel 11 is connected to the discharge pipe 12 for discharging materials. During operation, the auger pushes the material from a low position to a high position and discharges it from the discharge pipe 12.

[0044] The conveyor barrel 11 is rectangular in shape, and a top cover plate 14 is installed on the top of the conveyor barrel 11. The lower end of the top cover plate 14 is connected to a feeding hopper 141. Material is fed into the conveyor barrel 11 from the feeding hopper 141, and the material is pushed from the lower position to the higher position by the rotating auger before being discharged.

[0045] To address the difficulty in adjusting the tilt height of existing screw conveyors, which makes it challenging to load materials to different heights to meet production needs (such as loading materials onto trucks of different tonnages at varying heights), it is necessary to adjust the height of the discharge end of the conveyor drum 11.

[0046] Therefore, the present invention makes the following improvements:

[0047] The height screw conveyor also includes a hydraulic cylinder pulling mechanism 2 for adjusting the height of the screw conveyor mechanism 1.

[0048] Specifically, hydraulic cylinder pulling mechanisms 2 are hinged to the left and right sides of the conveyor barrel 11. The hydraulic cylinder pulling mechanisms 2 on both sides can pull and lift the heavy conveyor barrel 11, while maintaining a low posture during use to increase its safety and avoid occupying height space.

[0049] Specifically, the hydraulic cylinder pulling mechanism 2 includes a long pull arm 21 (thickened steel structure rod) hinged to the upper end of the conveyor barrel 11, and a pulling hydraulic cylinder is fixedly connected to the lower end of the long pull arm 21.

[0050] Specifically, the upper end of the long arm 21 is fixedly connected to a hinged upper seat, and the hinged upper seat is hinged to a pin fixedly connected to the side wall of the conveyor barrel 11.

[0051] Meanwhile, the traction cylinder is a multi-stage telescopic cylinder 22 (the multi-stage telescopic cylinder 22 is a conventional multi-stage telescopic cylinder disclosed in the prior art), and the pushing end (on the plunger rod) of the multi-stage telescopic cylinder 22 is fixed to the bottom of the long pull arm 21 through a connecting flange.

[0052] Correspondingly, the hydraulic cylinder pulling mechanism 2 also includes a hinged base 24, on which the lower end of the conveyor barrel 11 is hinged (by a pin). A mounting post is welded to the bottom of the hinged base 24, and a bottom bracket 3 is fixedly connected to the mounting post.

[0053] Meanwhile, the bottom of the cylinder of the multi-stage telescopic cylinder 22 is fixedly connected to a tongue seat 221, and a connecting shaft is fixedly connected between the tongue seats 211; the top of the bottom bracket 3 is connected to a fixed bracket 23, and the top of the fixed bracket 23 is fixedly connected to a hinged lower seat, which is hinged to the connecting shaft.

[0054] During operation, when it is necessary to adjust the height of the discharge end of the conveyor barrel 11, the multi-stage telescopic cylinder 22 in the hydraulic cylinder pulling mechanism 2 synchronously pulls the conveyor barrel 11 (during the pulling process, due to the hinge of the multi-stage telescopic cylinder 22, the multi-stage telescopic cylinder 22 flips). The heavy conveyor barrel 11 gradually increases in height under the pull. Since the multi-stage telescopic cylinder 22 is a conventional multi-stage telescopic cylinder 22 disclosed in the prior art, it can have multiple telescopic lengths, so as to adjust the lifting height of the conveyor barrel 11 in an adjustable manner during operation and achieve lifting at multiple height positions.

[0055] After being lifted to the target height, the operator conveys the material to the feeding hopper via a horizontally positioned conveyor. The material is then discharged from a height by being conveyed by the lifting conveyor cylinder 11.

[0056] This method greatly improves the flexibility of the screw conveyor, enabling the conveyor barrel 11 to be raised in an adjustable manner for feeding operations as needed. Furthermore, the entire process is fully automated, significantly improving operational efficiency.

[0057] Example 2

[0058] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, in order to increase the stability and safety of the conveyor barrel 11 feeding in the raised state and to avoid the upper end of the conveyor being heavy and the lower end being light, causing its head to tilt downward, the bottom support 3 is equipped with a tension arm structure on both sides, which provides support after the tension arm structure is opened.

[0059] The stability of the support on the ground is increased by using a cantilever structure.

[0060] Specifically, the boom structure includes boom rod 4 (which supports the bottom of the steel structure on the ground).

[0061] Specifically, the inner end of the boom 4 is hinged to the side wall of the bottom support 3. The inner end of the boom 4 has a hinge slot, and a hinge boss 31 is fixedly connected to the side wall of the bottom support 3, which is hinged in the hinge slot. The top and bottom of the hinge boss 31 are respectively hinged to the hinge slot by pins (specifically, at the top and bottom of the hinge slot).

[0062] During operation, the opening posture of the boom 4 is adjusted according to the lifting angle of the conveyor barrel 11. Because the boom 4 has a large supporting surface in the open state, it maintains the stability of the conveyor barrel 11 in the lifting state. If the lifting angle of the conveyor barrel 11 increases, the opening angle of the boom 4 is increased to match the increase in the lifting angle of the conveyor barrel 11. Conversely, if the conveyor barrel 11 lowers, the opening angle of the boom 4 is decreased to match the lowering of the conveyor barrel 11.

[0063] Increasing the opening amplitude of the boom 4 and decreasing its opening amplitude are intended to coordinate with the upward and downward height of the conveyor barrel 11, ensuring that the conveyor barrel 11 can be fully supported and stable.

[0064] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
