DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-4 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.
[0030] The embodiment of the present application discloses a concrete placing boom.
[0031] Reference Figure 1-3 A concrete placing machine of the present embodiment includes a silo 1 and a moving device 4, the moving device 4 is used to drive the movement of the silo 1, a discharge port 11 is opened on the silo 1, and a plurality of baffles 13 are slidably connected to the discharge port 11, an oil cylinder 12 is fixedly connected to the silo 1, there are a plurality of oil cylinders 12, and the plurality of oil cylinders 12 correspond to the plurality of baffles 13 respectively, one end of the output shafts of the plurality of oil cylinders 12 are respectively hingedly connected to the plurality of baffles 13, an oil pump 14 is also fixedly connected to the silo 1, and the plurality of oil cylinders 12 are fixedly connected to the oil pump 14 at the same time, and the oil pump 14 is used to simultaneously control the movement of the output shafts of the plurality of oil cylinders 12, so that the plurality of oil cylinders 12 can move together, which is convenient for the use of the silo 1.
[0032] Reference Figure 2-Figure 4The inner lining 2 is wound on the output shaft of the oil cylinder 12. The inner lining 2 is wetted with water. A zipper 21 is fixedly connected to the inner lining 2. When the inner lining 2 is set on the output shaft of the oil cylinder 12, the zipper 21 is in a closed state. By setting the zipper 21, the inner lining 2 can be taken out from the output shaft by pulling the zipper 21, which is convenient for removing, cleaning and replacing the inner lining 2. The zipper 21 includes a left tooth chain 211 and a right tooth chain 212. The left tooth chain 211 is fixedly connected to one end of the inner lining 2 in the length direction, and the right tooth chain 212 is fixedly connected to the middle section of the inner lining 2.
