AI Technical Summary
[0002]为适应市场变化，近年来木片作业量持续上升，2022年木片作业吞吐量占全年货物吞吐量的24.16%，2023年木片作业吞吐量占全年货物吞吐量的26.86%，木片为片状，含水率约50%，散货密度为326kg/m3，积载因数为3.07m3/t，木片作业主要包含四种工艺，分别为船—场；船—水平—驳；船—驳；场—驳，其中船—场和场—驳为主要作业方式，现有的“船—场”工艺流程为木片经自卸车运至场地后，装载机联合挖机将木片进行堆高储存，其中为了最大化利用现有场地资源，木片在堆场中堆存高度通常为10～15米挖机在将木片堆高过程中需要进行逐层堆叠，并用履带将其压实平整，在堆高过程中挖机的内燃机与木片接触频繁，整个作业过程存在坍塌、火灾等安全风险，同时挖机作业过程中还存在尾气排放等环境污染问题，为此现有大多数采用螺旋堆料机对木片进行输送，但由于木片含水率较高，高湿度会导致木片黏附在螺旋叶片和机槽内壁，形成结块并逐渐堆积，最终引发堵塞，因此需要停机对堵塞部位进行清理，从而降低木片输送的整体效率
[0010]本实用新型的技术效果和优点：木片输送开始之前，操作人员首先控制移动件向木片料堆移动，将收集框插入料堆中，随后通过驱动装置带动转动轴进行旋转，转动轴旋转的同时带动绞龙叶片同步运动，绞龙叶片将收集框两侧木片向中间进行输送，通过拨料杆能够将木片输送至传动带上，从而完成木片的输送，为了避免木片在收集框内出现堵塞现象，利用驱动电机带动驱动轴进行旋转，驱动轴旋转通过驱动槽能够使移动套筒上的控制杆在驱动槽内往复运动，从而使移动套筒在转动轴上左右移动挤压连接弹簧，进而能够对木片进行疏通，避免木片出现堵塞影响输送效率的问题，同时为了满足木片的堆放，可通过液压伸缩缸伸出不同长度调节输送件的角度，从而可使木片堆放得更高，减小相同数量木片的占地面积，同时“V”型布置的输送辊能够使传动带在输送木片时，对木片进行阻拦，避免木片在输送过程中出现掉落现象。

Description
Technical Field
[0001] This utility model belongs to the field of bulk material handling technology, specifically relating to a spiral stacker-reclaimer for wharf storage yards. Background Technology
[0002] To adapt to market changes, the volume of wood chip operations has been rising continuously in recent years. In 2022, wood chip operations accounted for 24.16% of the total annual cargo throughput, and in 2023, they accounted for 26.86%. Wood chips are in flake form with a moisture content of approximately 50%, a bulk density of 326 kg / m³, and a stowage factor of 3.07 m³ / t. Wood chip operations mainly include four processes: ship-to-yard; ship-to-horse-barge; ship-to-barge; and yard-to-barge. Among these, ship-to-yard and yard-to-barge are the main operating methods. The existing ship-to-yard process involves transporting wood chips to the site by dump trucks, where loaders and excavators stack the wood chips for storage. To maximize utilization... Using existing site resources, wood chips are typically stacked to a height of 10-15 meters in the stockpile. Excavators need to stack the wood chips layer by layer and compact them with tracks during this process. The excavator's internal combustion engine comes into frequent contact with the wood chips during stacking, posing safety risks such as collapse and fire. Furthermore, excavator operations generate exhaust emissions and other environmental pollution. Currently, most excavator operations use screw stackers to transport wood chips. However, due to the high moisture content of the wood chips, the high humidity causes them to adhere to the screw blades and the inner wall of the chute, forming clumps that gradually accumulate and eventually cause blockages. Therefore, the machine needs to be stopped to clear the blockages, thus reducing the overall efficiency of wood chip transport. Utility Model Content
[0003] The purpose of this invention is to provide a spiral stacker-reclaimer for dock storage yards to solve the above-mentioned problems.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a spiral stacker-reclaimer for wharf storage yards, comprising a main body, the main body including a moving component, the moving component including a connecting frame, the connecting frame having moving tracks on both sides of its bottom end, one end of the connecting frame being rotatably connected to a conveying component, and the other end of the connecting frame being connected to the conveying component via a hydraulic telescopic cylinder, the side of the conveying component away from the hydraulic telescopic cylinder being connected to a collecting component, one end of the conveying component being provided with a collecting frame, and two sets of rotating shafts being provided inside the collecting frame, the rotating shafts being provided through the inner wall of the collecting frame, auger blades being provided on both sides of the rotating shafts respectively, and a moving sleeve being provided in the middle of the auger blades, the moving sleeve having multiple material-pulling plates arranged in a ring on the outer circumferential surface of the moving sleeve, the rotating shafts rotating to drive the auger blades and material-pulling plates on both sides to move synchronously, so that the material in the collecting frame moves to the conveying component.
[0005] Preferably, the conveying component includes a support frame, a drive wheel, a drive belt, and a support structure. One end of the support frame is rotatably connected to the connecting frame, and the other end of the support frame is connected to the output end of the hydraulic telescopic cylinder. Both ends of the support frame are rotatably equipped with drive wheels, and drive belts are connected to the drive wheels on both sides. Multiple support mechanisms are provided below the drive belts.
[0006] Preferably, the support mechanism includes a connecting block and conveying rollers, wherein multiple conveying rollers are provided, and the conveying rollers are connected to the support frame through the connecting block, and the multiple conveying rollers are arranged in a "V" shape.
[0007] Preferably, the collecting component further includes a connecting spring and a control component. The auger blades on both sides are connected to the inner wall of the collecting frame through the connecting spring, and the auger blades on both sides are fixedly connected to the movable sleeve through the same connecting spring. A control component is provided in the middle of the auger blades on both sides. The control component drives the movable sleeve to move left and right to squeeze the connecting spring, so that the auger blades squeeze the connecting spring on the inner wall of the collecting frame in the rotation axis and reciprocate.
[0008] Preferably, the control component includes a drive motor, a drive shaft, a limit block, and a control rod. The drive motor is located between the two rotating shafts and is fixedly connected to one rotating shaft. The output end of the drive motor is connected to the drive shaft. The drive shaft is provided with a drive groove. The rotating shaft is provided with a limit groove. The inner wall of the movable sleeve is provided with a limit block and a control rod. The limit block is located in the limit groove, and the control rod is located in the drive groove.
[0009] Preferably, the drive groove consists of two spiral grooves with opposite directions of rotation. The rotation of the drive shaft causes the control rod to move within the drive groove, thereby causing the moving sleeve to move left and right on the rotating shaft.
[0010] The technical effects and advantages of this utility model are as follows: Before the wood chip conveying begins, the operator first controls the moving part to move towards the wood chip pile, inserts the collection frame into the pile, and then drives the rotating shaft to rotate through the drive device. Simultaneously, the rotating shaft drives the auger blades to move synchronously. The auger blades convey the wood chips from both sides of the collection frame towards the center. The wood chips are then conveyed onto the transmission belt via the feeding rod, thus completing the wood chip conveying. To prevent blockage in the collection frame, a drive motor drives the drive shaft to rotate. The rotation of the drive shaft, through the drive groove, causes the control rod on the moving sleeve to reciprocate within the drive groove. This causes the moving sleeve to move left and right on the rotating shaft, compressing the connecting spring, thereby clearing the blockage and preventing blockages that could affect conveying efficiency. Furthermore, to accommodate wood chip stacking, the angle of the conveying part can be adjusted by extending the hydraulic telescopic cylinder to different lengths, allowing for higher stacking and reducing the footprint of the same number of wood chips. Additionally, the "V"-shaped arrangement of the conveying rollers prevents the wood chips from falling during conveying by the transmission belt. Attached Figure Description

[0013] 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.
[0014] This utility model provides, for example Figures 1 to 6 The diagram shows a spiral stacker-reclaimer for a dock storage area, comprising a main body 1. The main body 1 includes a moving component 2, which includes a connecting frame 21. Moving tracks 22 are provided on both sides of the bottom of the connecting frame 21. A conveyor 3 is rotatably connected to one end of the connecting frame 21, and the other end of the connecting frame 21 is connected to the conveyor 3 via a hydraulic telescopic cylinder 23. A collecting component 4 is connected to the side of the conveyor 3 away from the hydraulic telescopic cylinder 23. A collecting frame 41 is provided at one end of the conveyor 3, and two sets of rotating shafts 42 are provided inside the collecting frame 41. The rotating shafts 42 penetrate the inner wall of the collecting frame 41. Screw blades 43 are respectively provided on both sides of the rotating shafts 42, and a moving sleeve 45 is provided in the middle of the screw blades 43. Multiple material-pulling plates 451 are arranged in a ring on the outer circumferential surface of the moving sleeve 45. The rotation of the rotating shafts 42 drives the screw blades 43 and the material-pulling plates 451 on both sides to move synchronously, causing the material in the collecting frame 41 to move onto the conveyor 3.
[0015] Specifically, the conveying component 3 includes a support frame 31, a transmission wheel 32, a transmission belt 33, and a support structure 34. One end of the support frame 31 is rotatably connected to the connecting frame 21, and the other end of the support frame 31 is connected to the output end of the hydraulic telescopic cylinder 23. Both ends of the support frame 31 are rotatably equipped with transmission wheels 32, and transmission belts 33 are connected to the transmission wheels 32 on both sides. Multiple support mechanisms are provided below the transmission belts 33.
[0016] Specifically, the support mechanism includes a connecting block 341 and a conveying roller 342. Multiple conveying rollers 342 are provided, and the conveying rollers 342 are connected to the support frame 31 through the connecting block 341. The multiple conveying rollers 342 are arranged in a "V" shape.
[0017] Specifically, the collecting component 4 also includes a connecting spring 44 and a control component 46. The auger blades 43 on both sides are connected to the inner wall of the collecting frame 41 through the connecting springs 44, and the auger blades 43 on both sides are fixedly connected to the movable sleeve 45 through the same connecting springs 44. The control component 46 is provided in the middle of the auger blades 43 on both sides. The control component 46 drives the movable sleeve 45 to move left and right to squeeze the connecting springs 44, so that the auger blades 43 squeeze the connecting springs 44 against the inner wall of the collecting frame 41 on the rotating shaft 42 and reciprocate.
[0018] Specifically, the control component 46 includes a drive motor 461, a drive shaft 462, a limiting block 463, and a control rod 464. The drive motor 461 is located between the two rotating shafts 42 and is fixedly connected to one side of the rotating shaft 42. The output end of the drive motor 461 is connected to the drive shaft 462. The drive shaft 462 is provided with a drive groove 4621. The rotating shaft 42 is provided with a limiting groove 421. The inner wall of the movable sleeve 45 is provided with a limiting block 463 and a control rod 464. The limiting block 463 is located in the limiting groove 421, and the control rod 464 is located in the drive groove 4621.
[0019] Specifically, the drive groove 4621 is composed of two spiral grooves with opposite directions of rotation. The rotation of the drive shaft 462 causes the control rod 464 to move within the drive groove 4621, thereby causing the moving sleeve 45 to move left and right on the rotating shaft 42.
[0020] Working principle and process: Before the wood chip conveying begins, the operator first controls the moving part 2 to move towards the wood chip pile, inserting the collection frame 41 into the pile. Then, the operator controls the extension length of the hydraulic telescopic cylinder 23 according to the required stacking height of the wood chips. After the conveying angle is adjusted, the extension of the hydraulic telescopic cylinder 23 is stopped, and the angle of the support frame 31 is fixed. At this time, the drive device drives the rotating shaft 42 to rotate. Both rotating shafts 42 are driven by the same motor, and both motors are driven simultaneously using existing technology. When the rotating shaft 42 rotates, the auger blades 43 and the feeding rod move synchronously. To avoid blockage in the collection frame 41, the drive motor 461 drives the drive shaft 462 to rotate. The rotation of the drive shaft 462, through the drive groove 4621 set on it, causes the control inside the moving sleeve 45 to move. The control rod 464 slides along the drive groove 4621, causing the movable sleeve 45 to reciprocate on the rotating shaft 42. To prevent the movable sleeve 45 from rotating with the drive shaft 462, the limiting block 463 moves within the limiting groove 421, thus preventing the movable sleeve 45 from rotating and allowing it to reciprocate only on the rotating shaft 42. The reciprocating motion of the movable sleeve 45 compresses the connecting spring 44, while the auger blades 43 compress the connecting spring 44 into the collection frame 41, thereby clearing the blockage of wood chips. If the collection frame 41 is not blocked, blockage can be avoided, preventing the wood chips from affecting the conveying efficiency. At the same time, the "V"-shaped conveying roller 342 can block the wood chips when the transmission belt 33 is conveying them, preventing the wood chips from falling during the conveying process.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
