Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an adaptive spiral material splicing device. Background Art

[0002] As a continuous and efficient ship unloading equipment, the screw ship unloader mainly consists of a feeding head, a vertical screw conveying part and a horizontal screw conveying part. When the screw ship unloader is working, the feeding head rotates in the opposite direction to squeeze the material into the vertical screw conveying section. The material is then sent from the vertical screw part to the horizontal screw and then to the designated position. At present, when the existing screw ship unloader feeding head enters the cabin to work, there is a concern that the feeding head will directly contact the bottom of the cabin, causing wear or failure of the feeding head, thereby reducing the service life of the feeding head. Therefore, when the ship unloader feeding head stops descending, it is still a long distance from the bottom of the cabin, which directly reduces the working efficiency of the screw ship unloader and increases the workload of the subsequent manual clearance task. In addition, it is difficult to accurately dock the existing screw ship unloader with the receiving bin, and it is impossible to adaptively adjust the buffer strength according to the material conditions, which can easily cause the screw ship unloader to be stuck by the material, affecting the unloading.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed a variety of solutions. For example, a Chinese patent document discloses a screw ship unloader reclaiming device [CN202011441986.8], which includes an outer spiral tube, an outer scraper, a universal ball device, and a suction device. The outer spiral tube is provided with a feed port at the lower end of its outer wall. One side of the outer scraper is connected to one side of the feed port, and the other side of the outer scraper and the outer wall of the outer spiral tube form an opening leading to the feed port, with the opening direction being the same as the rotation direction of the outer spiral tube. The universal ball device is located on the other side of the feed port. The universal ball device is compact and lightweight, with a simple structure, easy to replace and maintain. While protecting the screw unloader's bottom plate and the bottom of the feed head, it also increases the screw unloader's reclaiming efficiency. The suction device further improves the feed head's reclaiming efficiency by sucking materials at high pressure, reducing the workload of manual cleaning of the ship's hold later, and extending the service life of the screw unloader's feed head.

[0004] The above solution has solved to a certain extent the problem in the prior art that the feed head of the ship unloader is easily worn or malfunctioned, which leads to low working efficiency. However, this solution still has many shortcomings. For example, it is difficult to accurately connect the screw ship unloader with the receiving bin, and the buffer strength cannot be adaptively adjusted according to the material conditions, which can easily cause the screw ship unloader to be stuck by the material, affecting unloading.

[0038] Furthermore, the linkage locking assembly 6 includes a linkage seat 61 arranged on the circumferential outside of the fixed unloading barrel 2, and the outer wall of the linkage seat 61 is connected to a connecting hook 62 arranged at an angle, and a supporting link 63 is also provided on the linkage seat 61.

[0039] More specifically, the connecting hook 62 has an inclined blocking portion 621 , one end of which is provided with a U-shaped hooking portion 622 , and a connecting groove 623 is formed on the inner side of the hooking portion 622 for the hooking rod 374 to be inserted into.

[0040] In detail, the buffer material receiving mechanism 5 includes an annular sliding mounting seat 51 circumferentially arranged on the inner side of the fixed unloading barrel 2, and a plurality of lifting and swinging material receiving plates 52 extending toward the interior of the fixed unloading barrel 2 are provided on the inner side of the annular sliding mounting seat 51. The ends of the lifting and swinging material receiving plates 52 are slidingly and liftingly arranged on the annular sliding mounting seat 51 through an annular lifting clamp 53, and the lifting and swinging material receiving plates 52 located inside the fixed unloading barrel 2 are cross-staggered.

One end of the swing connecting rod 55 is connected to the annular lifting clamp 53 and the other end is connected to the above-mentioned linkage seat 61.

[0041] When the material falls into the lifting swing material receiving tray 52, the lifting swing material receiving tray 52 is forced to slide down, and the greater the material pressure, the greater the downward force of the lifting swing material receiving tray 52. The downward force is reduced by the elastic activity of the linkage locking component 6 and the adaptive locking device 3 to achieve buffering.

[0042] Preferably, the locking connection mechanism 4 includes a fixed connection seat 41 arranged on the circumferential outside of the spiral feed frame 11, a rotating adjustment seat 42 is provided at the upper end of the fixed connection seat 41 and a cylinder fixing seat 43 is provided at the lower end, a rotating drive cylinder 44 is provided on the cylinder fixing seat 43, a connecting plate frame 45 is rotatably provided on the rotating adjustment seat 42, and the lower end of the connecting plate frame 45 is connected to the output end of the rotating drive cylinder 44 through a rotating connecting shaft 46, and the upper end of the connecting plate frame 45 is provided with a locking connecting rod 47, one end of which can be inserted into the sliding connection groove 344.

[0043] In addition, the spiral feeder 1 is arranged at an angle and the spiral feeding frame 11 is connected to the inside of the spiral feeder 1.

The adaptive locking device 3 is installed on the outer wall of the protective sleeve 14.

[0044] In summary, the principle of this embodiment is as follows: the spiral feeder 1 rotates so that the spiral feed frame 11 is located below the fixed discharge barrel 2, the driving cylinder 33 is started, and the rotating connecting rod 35 is driven to rotate, so that the hooking link 374 is stuck in the connecting groove 623, and the positioning between the spiral feeder 1 and the fixed discharge barrel 2 is realized. Secondly, the rotating driving cylinder 44 is started, and the connecting plate frame 45 is driven to rotate, so that one end of the locking link 47 is stuck in the sliding connecting groove 344, thereby improving the positioning stability; the material is moved from the fixed discharge barrel 2 to the fixed discharge barrel 2. The material falls from the top of the discharge barrel 2 and passes through the lifting and swinging material receiving tray 52. The lifting and swinging material receiving tray 52 slides downward when subjected to force. Due to the setting of the swing shaft 54, the pressure on the lifting and swinging material receiving tray 52 is transmitted to the connecting hook 62, and the connecting hook 62 moves upward. However, due to the limitation of the connecting frame 373, the upward movement stroke of the connecting hook 62 is limited. Therefore, the downward movement stroke of the lifting and swinging material receiving tray 52 is synchronously limited, so that the lifting and swinging material receiving tray 52 provides an adaptive buffering force according to the falling pressure of the material.
