[0002] Tower crane hoppers, as a type of concrete unloading mechanism, consist of a hopper and an output pipe. They are primarily used in concrete pouring for building foundations, transporting and mixing concrete, and in high-rise building construction such as plastering, piling, and ring beam installation. During unloading, if attached... Figure 1 As shown, the silo is lifted up, and the length of the output pipe can be changed by setting a foldable output pipe, which allows the concrete to be poured to a pouring position at a greater distance.

[0003] However, during use, it was found that after folding and extending, the output tube could only be changed to a fixed length. If it was necessary to pour the material between the output tubes, the position of the silo had to be changed. Furthermore, the existing output tubes were all connected to the outer wall of the silo by welding. When it was necessary to pour the material around the silo, it was necessary to manually rotate the silo to rotate and move the output tube to the designated location, which was labor-intensive.

[0019] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Please see Figures 2 to 7 This application proposes a concrete feeding mechanism, including a hopper 1, a corrugated pipe 3, and a positioning structure. The hopper 1 is provided with an output pipe 2, and the corrugated pipe 3 has a connecting end and an output end. The connecting end is connected and communicates with the output pipe 2. The positioning structure is provided at the connection between the corrugated pipe 3 and the output pipe 2 to adjust the direction and angle of the output end and to fix the concrete output from the output end for pouring.

[0022] In the embodiments provided in this application, when pouring is required at a specific location, the concrete in the hopper 1 is discharged to the pouring location. The corrugated pipe 3 can be rotated to the direction of the pouring location, and then the corrugated pipe 3 can be lengthened or shortened to align its output end with the pouring location. Finally, the output end of the corrugated pipe 3 is stably positioned using a positioning structure, allowing the hopper 1 to be opened and the concrete discharged to the desired pouring location. This allows for pouring over a larger area while saving manpower. For example, Figure 2 As shown, the output pipe 2 and the corrugated pipe 3 can be arranged at an angle downwards to facilitate the output of concrete from the silo 1.

[0023] Please see Figures 2 to 5 The positioning structure includes a clamp 4, a mating part 12, a rotating part 5, and a positioning part 11. The clamp 4 is detachably fitted onto the connecting end to connect the corrugated pipe 3 and the output pipe 2. The mating part 12 is fixedly connected to the clamp 4. One end of the rotating part 5 is provided with a rotating shaft 8. The end of the rotating shaft 8 away from the rotating part 5 passes through the mating part 12 and is rotatably connected to the clamp 4. The rotating shaft 8 is provided with a sliding groove 10. The other end of the rotating part 5 is connected to the output end, allowing the corrugated pipe 3 to extend and shorten. The positioning part 11 is fitted onto the rotating shaft 8. The surface of the positioning part 11 near the rotating shaft 8 is provided with a slider 111. The slider 111 is movably inserted into the sliding groove 10, so that the positioning part 11 has a locked position and an unlocked position during its active stroke. In the locked position, the positioning part 11 engages with the mating part 12 to restrict the rotation of the rotating shaft 8. In the unlocked position, the positioning part 11 disengages from the mating part 12, allowing the rotating shaft 8 to rotate. Since the clamp 4 is detachably fitted onto the connecting end, it facilitates the replacement or maintenance of the entire positioning structure. Four slide grooves 10 can be configured, spaced apart on the circumferential wall of the rotating shaft 8, and four sliders 111 can also be configured. Thus, when the positioning part 11 and the mating part 12 are engaged, the positioning effect of the mating part 12 on the positioning part 11 and the rotating shaft 8 is improved.

[0024] When concrete needs to be poured, pull up the positioning part 11. The positioning part 11 moves upward along the extension direction of the slide groove 10 and disengages from the mating part 12. When the positioning part 11 remains disengaged from the mating part 12, that is, when the positioning part 11 is in the unlocked position, manually rotate the rotating part 5. When the rotating part 5 rotates, it can drive the bellows 3 to bend. When the output end of the bellows 3 is in the direction of the pouring position, the bellows 3 is extended to the corresponding pouring position. The bellows 3 remains connected to the rotating part 5 during the extension process. When the output end of the bellows 3 corresponds to the pouring position, release the positioning part 11. The positioning part 11 moves downward under the action of gravity and engages with the mating part 12. Alternatively, the positioning part 11 can be manually pushed down to engage with the mating part 12. Since the mating part 12 is fixed on the pipe clamp 4, the slider 111 on the positioning part 11 is inserted into the slide groove 10 of the rotating shaft 8, which can prevent the rotating shaft 8 from continuing to rotate, thereby positioning the rotating part 5 and the bellows 3.

[0025] To enable the positioning part 11 to engage with the mating part 12, the positioning part 11 may include an annular positioning plate and multiple locking blocks. The locking blocks are spaced circumferentially along the surface of the annular positioning plate near the mating part 12. The mating part 12 may include an annular mating plate and multiple slots. The slots are spaced circumferentially along the surface of the annular mating plate near the positioning part 11, and the slots and locking blocks can engage. In some embodiments of this application, the mating part 12 includes a first end face gear 12a, and the positioning part 11 includes a second end face gear 11a. In the locked position, the first end face gear 12a meshes with the second end face gear 11a; in the unlocked position, the second end face gear 11a disengages from the first end face gear 12a. Since the first end face gear 12a is fixed to the clamp 4, when the first end face gear 12a meshes with the second end face gear 11a, the first end face gear 12a can restrict the rotation of the second end face gear 11a, thereby positioning the rotating member 5.

[0026] To facilitate the smooth engagement of the positioning part 11 and the mating part 12, in some embodiments of this application, the rotating shaft 8 is fitted with an elastic element 9, with both ends of the elastic element 9 connected to the rotating part 5 and the positioning part 11, respectively. Thus, when the positioning part 11 is released, it moves downwards under its own weight and the elastic force of the elastic element 9, quickly engaging with the mating part 12.

[0027] To ensure that the bellows 3 remains connected to the rotating component 5 when it is lengthened or shortened, refer to... Figure 6The rotating component 5 may include a rotating rod 52 and a fixed plate 53. One end of the rotating rod 52 is provided with a rotating shaft 8, one end of the fixed plate 53 is slidably sleeved on the rotating rod 52, and the other end of the fixed plate 53 is connected to the bellows 3. Thus, the bellows 3 can be extended and shortened when the fixed plate is slidably fixed. See some embodiments of this application. Figure 2 and Figure 3 The rotating component 5 includes a telescopic rod 51, one end of which is provided with the rotating shaft 8, and the other end is connected to a mounting ring, which is fixedly sleeved on the output end. By extending and shortening the telescopic rod 51, the bellows 3 can be extended and shortened. Furthermore, when the bellows 3 is shortened, the telescopic rod 51 can also be shortened, saving space occupied by the rotating component 5 and facilitating worker operation.

[0028] To prevent excessive sagging of the middle section of the corrugated pipe 3 after it has been elongated and to reduce the likelihood of damage when concrete passes through it, in some embodiments of this application, the rotating member 5 is provided with a lifting ring 6, which is fitted over the corrugated pipe 3. Multiple lifting rings 6 can be provided, and multiple lifting rings 6 fitted over the corrugated pipe 3 can improve the lifting effect. Alternatively, a lifting cylinder can be used to further enhance the lifting effect.

[0029] To make the length of the output pipe 2 adjustable and increase the casting range of the corrugated pipe 3, please refer to... Figure 3 and Figure 7 In some embodiments of this application, the concrete production feeding mechanism further includes a threaded rod 7. The output pipe 2 includes a first discharge pipe 22 and a second discharge pipe 21. The first discharge pipe 22 is connected to the connecting end. One end of the second discharge pipe 21 is connected to the hopper 1, and the other end extends into the first discharge pipe 22. The second discharge pipe 21 has a plurality of columnar grooves 211 arranged at intervals along its length. The first discharge pipe 22 has a through hole, and the threaded rod 7 is threadedly connected to the through hole and the columnar grooves 211. By gradually extending the second discharge pipe 21 into the first discharge pipe 22, the pouring distance of the corrugated pipe 3 can be changed. When the second discharge pipe 21 extends into the first discharge pipe 22, the threaded rod 7 is sequentially inserted and threadedly connected to the through hole and the columnar grooves 211, thereby fixing the second discharge pipe 21 and the first discharge pipe 22 together. The first discharge pipe 22 can be provided with a horizontally extending mounting surface, and the mounting surface is provided with a through hole, which can increase the contact area between the top of the threaded rod 7 and the top of the first discharge pipe 22, so that the threaded rod 7 and the first discharge pipe 22 are more tightly abutted.

[0030] Working principle: In use, pull up the second end face gear 11a. The second end face gear 11a moves upward along the extension direction of the slide groove 10 and disengages from the mating part 12. When the second end face gear 11a remains disengaged from the first end face gear 12a, that is, when the positioning part 11 is in the unlocked position, manually rotate the rotating part 5. When the rotating part 5 rotates, it can drive the bellows 3 to bend. When the output end of the bellows 3 is in the direction of the pouring position, the bellows 3 extends to the corresponding pouring position. The bellows 3 remains connected to the rotating part 5 during the extension process. When the output end of the bellows 3 is in the pouring position, release the first end face gear 12a. The first end face gear 12a moves downward under the action of gravity and engages with the second end face gear 11a, which can prevent the rotating shaft 8 from continuing to rotate, thereby positioning the bellows 3.
