[0002] A wind farm is a place where wind energy is captured, converted into electrical energy and fed into the power grid through transmission lines. Wind power generation is the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. Using wind power to generate electricity is very environmentally friendly and has huge wind energy reserves. Wind power equipment relies on wind turbines to convert wind energy. In order to provide stable installation support for wind turbines, the tower base needs to be cast at the bottom of the wind tower.

[0003] During the construction of the wind turbine concrete tower base, concrete needs to be evenly filled into the interior of the prefabricated mold. Due to the large area of ​​the wind turbine tower base, it is difficult for personnel to go deep into the casting frame, so a suspended casting method is often used. During the casting process, the concrete material in the silo is prone to sedimentation and agglomeration, which not only affects the casting quality but also easily leads to blockage of the material port or uneven material feeding, affecting the construction operation.

[0015] The present invention also provides a method for using a concrete feeding device for wind farm construction, comprising the following steps:

[0016] S1. Installation of the device. The device is used in conjunction with external lifting equipment. When working, the concrete barrel is installed on the lifting part of the lifting equipment through the lifting ring seat, and then the concrete material is filled into the interior of the concrete barrel;

[0017] S2, pre-mixing of materials. According to the pouring needs, the concrete barrel is moved to the top of the pouring station. The concrete materials are pre-mixed before pouring. During mixing, the driving motor drives the driving shaft to rotate clockwise. During rotation, the straight surface of the end of the transmission block is engaged with the notch on the side of the one-way slot, driving the synchronous rotation of the stirring drive column and the feeding worm to stir and mix the materials in the concrete barrel. At the same time, the feeding worm conveys the materials in reverse to prevent the materials from being squeezed to the feeding port.

[0018] S3, pouring and unloading. After the pre-mixing work is completed, when unloading, the concrete barrel is lowered to the unloading height. Then, under the upward pulling action of the cover driving cylinder body, the material port cover is flipped down and opened. At the same time, the driving motor drives the driving shaft to rotate counterclockwise. During rotation, the arc surface of the end of the transmission block and the arc surface of the side of the one-way slot slide and fit together to lose the transmission effect, driving the feeding worm to rotate alone. The spiral pattern on the upper part of the feeding worm completes the stable unloading and transportation of the concrete material. During the unloading process, the unloading speed can be accurately controlled by changing the rotation speed of the feeding worm to complete the unloading work;

[0019] S4, back loading, after the unloading work is completed, the feeding worm stops rotating, and at the same time, under the downward push of the cover driving cylinder, the material inlet cover flips up and closes, and then the concrete barrel moves out of the working area for refilling of concrete materials.

[0020] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects:

[0021] 1. This material discharge device adopts a built-in anti-condensation stirring structure. A stirring driving column is arranged inside the concrete barrel. Before pouring and discharging, the stirring driving column rotates to drive the stirring rod column to stir and mix the concrete materials in the concrete barrel to improve the uniformity and fluidity of the concrete, which is beneficial to improving the pouring quality and the smoothness of discharging.

[0022] 2. A worm-type feeding structure is adopted. A feeding worm is arranged on the lower discharge side of the concrete barrel. The feeding worm is independently driven by a driving motor, which can stably feed and convey materials to avoid material blockage. Compared with the traditional flow feeding method, it has better working stability, and the speed control can achieve precise control of the discharge amount. The automatic opening and closing material port cover can control the feeding amount more accurately, which is conducive to improving the casting quality.

[0023] 3. A one-way transmission structure is adopted. The stirring drive column and the driving shaft at the bottom of the driving motor are connected and transmitted through a transmission block and a spring. When rotating forward, the transmission block and the one-way slot on the upper part of the driving shaft are limitedly engaged, which can realize the synchronous driving of the stirring drive column and the feeding worm to complete the mixing and stirring of the materials. When rotating reversely, the arc side sliding connection between the transmission block and the one-way slot loses the transmission effect, which can realize the separate driving of the feeding worm, and complete the material unloading work through the feeding worm. During the unloading process, the rotation of the feeding worm is not affected by the resistance of the stirring drive column, and the unloading of concrete materials can be completed more flexibly and accurately.

After the pre-mixing work is completed, when unloading, the concrete barrel (1) is lowered to the unloading height, and then under the upward pulling action of the cover driving cylinder (3), the material port cover (2) is flipped down and opened, and at the same time, the driving motor (9) drives the driving shaft to rotate counterclockwise. During rotation, the arc surface of the end of the transmission block (12) and the arc surface of the side of the one-way slot (17) are slidably engaged and lose the transmission effect, driving the feeding worm (11) to rotate independently. The spiral pattern on the upper part of the feeding worm (11) completes the stable unloading and transportation of the concrete material. During the unloading process, the unloading speed can be accurately controlled by changing the rotation speed of the feeding worm (11) to complete the unloading work; S4, back loading, after the unloading work is completed, the feeding worm (11) stops rotating, and at the same time, under the downward push of the cover driving cylinder (3), the material inlet cover (2) flips up and closes, and then the concrete barrel (1) moves out of the working area to reload the concrete material.
