[0002] In the pulp and paper industry, as a key raw material, the storage method of wood chips directly affects production efficiency, cost control and product quality. At present, the widely adopted wood chip storage method in the industry is to stack and store the wood chips in a straight-line stacking manner.

[0003] During the straight-line stacking process, the wood chips are stacked along a straight line or parallel lines, and are usually simply stacked into rows of parallel stacks. Large gaps are easily formed between the stacks, especially when the shapes and sizes of the wood chips are inconsistent, and such gaps are more significant, thus reducing the overall space utilization rate and increasing the storage cost.

[0004] Moreover, when taking materials, it is usually only possible to strip layer by layer from the top of the stack first, which means that the wood chips at the bottom are often ignored for a long time, are difficult to be utilized in time, and the principle of first-in, first-out material taking cannot be realized.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] The following combines Figures 1 to 2 to describe a rotary stacking device according to an embodiment of the present invention.

[0029] A rotary stacking device includes a central column 1, a rotary assembly, a stacking assembly 3, and a counterweight assembly 4; the bottom of the central column 1 is vertically installed on the ground, the top of the central column 1 is provided with a rotary assembly and a stacking assembly 3, the rotary assembly is used to rotate the stacking assembly 3, the stacking assembly 3 includes a feeding chute 31 and a conveying member 32, the input end of the feeding chute 31 is communicated with an external feeder, the output end of the feeding chute 31 is communicated with the conveying member 32, and the conveying member 32 is used to convey wood chips to one end away from the central column 1.

[0030] The operation process of a rotary stacking device of this solution is as follows: An external feeder conveys a large amount of wood chips to the feeding chute 31, the wood chips slide onto the conveying member 32 under the guidance of the feeding chute 31, the conveying member 32 conveys the wood chips to one end away from the central column 1, when the wood chips are at the output end of the conveying member 32, the wood chips fall from a high altitude to the ground, and finally form a material pile with a large bottom and gradually shrinking upward. At this time, the staff can take the wood chips at the bottom and on the outer side of the material pile according to the principle of first in first out, effectively reducing the mildew situation caused by the long-term storage of wood chips.

[0031] The rotary assembly drives the feeding chute 31 and the conveying member 32 to rotate together, so that the feeding chute 31 and the conveying member 32 start to rotate around the central column 1. The precise control of the rotary assembly ensures the smooth rotation of the stacking assembly 3 and avoids vibration and deviation. It is worth noting that the conveying member 32 is preferably a belt conveyor. The conveying member 32 continuously works during the rotation process and conveys the wood chips output from the feeding chute 31 to one end away from the central column 1.

[0032] With the continuous conveying of wood chips and the rotation of the stacking assembly 3, the wood chips gradually form an annular material pile around the central column 1 on the ground, and the largest material pile can store 387,000 cubic meters of wood chips. During this process, the counterweight assembly 4 plays a role in balancing the overall weight of the stacker, ensuring the stability and safety of rotation.

[0033] Due to the mutual cooperation of the rotary assembly and the stacking assembly 3, the wood chips are stacked around the central column 1. This method makes full use of the space, enabling more wood chips to be stacked under the same floor area. Compared with the traditional linear stacking method, the surrounding stacking significantly increases the stacking quantity and effectively solves the problems of low space utilization and easy mildew of the wood chips at the bottom in the traditional linear stacking method.

[0034] The counterweight assembly 4 includes a counterweight block 41, a first counterweight mounting rod 42, a second counterweight mounting rod 43, and a third counterweight mounting rod 44, and the counterweight block 41 and the conveying member 32 are respectively located on both sides of the central column 1;

[0035] The first counterweight mounting rod 42 is obliquely connected to the central column 1 and the end of the counterweight 41 away from the central column 1, and the first counterweight mounting rod 42, the counterweight 41 and the central column 1 form a triangular structure;

[0036] The second counterweight mounting rod 43 is obliquely connected to the top of the central column 1 and the end of the conveying member 32 away from the central column 1, and the third counterweight mounting rod 44 is obliquely connected to the bottom of the central column 1 and the end of the conveying member 32 away from the central column 1. The central column 1, the second counterweight mounting rod 43 and the third counterweight mounting rod 44 form a triangular structure.

[0037] Through the two triangular structures, the stability and anti-overturning ability of the overall structure can be greatly enhanced, the vibration and impact force generated during the conveying process can be effectively dispersed, the shaking of the central column 1 can be reduced, and thus the running stability of the conveying member 32 under heavy load conditions can be significantly improved.

[0038] Moreover, in case of accidents (such as sudden increase in load, external impact, etc.), the triangular structure can better protect the conveying member 32 and the wood chips it carries, preventing safety accidents caused by structural instability. At the same time, the reasonable distribution of the counterweight also reduces the center of gravity of the system, further improves the overall anti-overturning ability, and ensures the safety of the operators.

[0039] The slewing assembly includes a slewing motor, a slewing bearing and a support sleeve;

[0040] The slewing motor is fixedly connected to the support sleeve, the slewing motor is used to drive the support sleeve to rotate, and the support sleeve is rotatably mounted on the outside of the central column 1 through the slewing bearing;

[0041] The stacking assembly 3 and the counterweight assembly 4 are both mounted on the support sleeve.

[0042] It should be noted that the slewing motor is preferably a reduction motor (the specific structure of the slewing assembly is not shown in the figure). The reduction motor can accurately and stably drive the support sleeve, the stacking assembly 3 and the counterweight assembly 4 to perform continuous or intermittent rotational motion, greatly improving the flexibility of the stacking operation. Moreover, using the central column 1 as the support component ensures that the support sleeve can still maintain a stable operating state when rotating or bearing a large load, extends the service life of the equipment, and improves the comfort of the working environment.

[0043] The stacking assembly 3 includes at least one conveying member 32. The input end of the conveying member 32 close to the central column 1 is communicated with the output end of the feeding chute 31, the output end of the conveying member 32 close to the central column 1 is communicated with the input end of the adjacent conveying member 32, and the multiple conveying members 32 are connected end to end to form a straight line.

[0044] With the increase in the number of conveying members 32 and the adoption of a layout where multiple conveying members 32 are connected end to end to form a straight line, not only can the wood chips be flexibly transported along this straight line to a wider area far from the central column 1, but also the stacking area that the stacker of this solution can cover is significantly enlarged. This means that within the same time, the stacker can stack more wood chips, thereby improving the working efficiency and the storage capacity of the yard and reducing the cost of storing per unit of wood chips.

[0045] By changing the number of conveying members 32, the operation flexibility of the stacker can be greatly enhanced, enabling it to adapt to the requirements of stacking sites with different shapes and sizes and improving the adaptability of the stacking operation.

[0046] An anemometer 33 is provided at the end of the conveying member 32 far from the central column 1. The anemometer 33 is used to detect the current wind speed. The anemometer 33 is electrically connected to the slewing motor and the conveying member 32.

[0047] By being electrically connected to the slewing motor, the anemometer 33 can transmit the detected wind direction information to the control system. According to the wind direction data, when the wind speed exceeds 50 - 75 km / h, the control system intelligently adjusts the rotation direction and speed of the slewing motor, thereby driving the overall rotation of the central column 1 and the conveying member 32 to the optimal stacking angle. This intelligent direction adjustment strategy ensures that the wood chips can be stacked along the direction opposite to the wind direction or the direction with the least resistance, effectively improving the stability and efficiency of stacking.

[0048] Moreover, according to the wind direction data, the conveying speed of the conveying member 32 can also be adjusted. In the case of a large wind speed, the conveying speed can be appropriately reduced or the stacking density can be increased to reduce the risk of the wood chips being blown away by the wind; when the wind speed is small or the wind direction is stable, the conveying speed can be increased or the stack shape can be adjusted to maximize the stacking capacity and efficiency.

[0049] An observation platform 5 is provided at the top of the central column 1. The observation platform 5 is located above the input end of the feeding chute 31. By observing the input end of the feeding chute 31, the operator can understand the supply situation of the wood chips in real time and adjust the feeding speed and quantity according to the actual needs. This precise control of the wood chip supply helps to optimize the operation process, improve the efficiency and accuracy of the stacking operation. At the same time, the operator can also adjust the stacking strategy in a timely manner according to the change of the stack shape to ensure the uniformity of the stack shape and density.

[0050] An escape ladder is provided inside the central column 1, and two escape openings are provided on the side wall of the central column 1, and the escape ladder vertically connects the two escape openings. The escape ladder directly connects the two escape openings to form a vertical escape passage. In the event of fire, mechanical failure or other emergency situations, personnel can quickly evacuate from a high place to the ground or other safe areas via the escape ladder. This vertical evacuation method is more efficient than horizontal evacuation, and can greatly shorten the escape time and reduce the risk of casualties.

[0051] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
