[0006] By adopting the above technical solutions, real-time stirring of the discharging hopper can be achieved. Depending on the effect of stirring, the work performance of the concrete can be greatly improved, the quality of concrete pouring and the appearance quality of the concrete can be improved; even if the concrete stays in the discharging hopper for a slightly longer time or the slump of the concrete is small, very good discharging effect can be achieved through the stirring of the discharging hopper, reducing the non-production loss of the concrete; the workability of the concrete can be improved, the time for discharging the concrete can be shortened and the pouring process can be optimized.

Detailed implementation manners
[0013] The following further describes the present invention in detail with reference to the attached Figure 1 - attached Figure 2 drawings.
[0014] An embodiment of the present invention discloses a concrete discharging hopper with a self - stirring function. Referring to Figure 1 and Figure 2 , the concrete discharging hopper with a self - stirring function includes a hopper body 1. Support legs 2 are fixed on the side wall at the bottom of the hopper body 1. A lifting ring 3 is fixed on the top edge of the hopper body 1. A discharging port is provided at the bottom of the hopper body 1, and a hopper door 4 for opening and closing the discharging port is provided below the discharging port.
[0015] Referring to Figure 1 and Figure 2 , the hopper door 4 includes an arc - shaped baffle plate 40. The arc - shaped opening of the baffle plate 40 faces upward. Connecting plates 41 are vertically fixed at both ends of the baffle plate 40. The top ends of the connecting plates 41 are hinged to the side wall of the hopper body 1. A door opening rod 5 is vertically arranged on one side of the hopper body 1. The bottom end of the door opening rod 5 is hinged to the support leg 2. A connecting rod 50 is hinged between the door opening rod 5 and the baffle plate 40. By pulling the door opening rod 5 outwards, the door opening rod 5 drives the connecting rod 50 to move, and the connecting rod 50 drives the baffle plate 40 to rotate, thereby opening the discharging port. The door opening rod 5 and the connecting rod 50 form a door opening mechanism.
[0016] Referring to Figure 1 and Figure 2 , a hook 10 is fixed on the side wall of the hopper body 1. The door opening rod 5 is detachably clamped in the hook 10, thereby restricting the rotation of the door opening rod 5, and further making the baffle plate 40 in a state of closing the discharging port. A stirring shaft 6 is rotatably installed along the length direction inside the hopper body 1. A plurality of stirring blades 7 are fixed on the outer wall of the stirring shaft 6 along the length direction. A driving mechanism 8 for driving the stirring shaft 6 to rotate is installed on the outer wall of the hopper body 1.
[0017] Referring to Figure 1 and Figure 2, in this embodiment, the driving mechanism 8 is a structure form of a motor combined with a speed reducer. The driving mechanism 8 drives the stirring shaft 6 to rotate, and the stirring shaft 6 drives the stirring blades 7 to rotate, thereby stirring the concrete inside the hopper body 1. A controller 9 for controlling the start and stop of the driving mechanism 8 is also installed on the outer wall of the hopper body 1. The controller 9 and the driving mechanism 8 are connected to the power supply through wires to supply power during the working process.
[0018] The implementation principle of the concrete discharging hopper with self-stirring function in the embodiment of the present invention is as follows: turn on the switch of the controller 9, the driving mechanism 8 works, and the stirring starts. When the hopper body 1 can be normally stirred during no-load stirring operation, turn off the controller 9; fill the inside of the hopper body 1 with concrete and hoist it to the area to be poured, pull the opening rod 5 to drive the baffle 40 to move, so that the discharging port is in an open state.
[0019] At the same time, turn on the switch of the controller 9 to make the stirring blades 7 start to stir the concrete, so as to achieve the purpose of discharging and stirring the concrete at the same time; after the discharging is completed, operate the opening rod 5 to close the discharging port and turn off the controller 9; finally, after the concrete pouring is completed, clean the hopper body 1, the stirring shaft 6 and the stirring blades 7, and turn off the power supply of the controller 9.
[0020] The concrete discharging hopper with self-stirring function in the embodiment of the present invention can realize real-time stirring of the discharging hopper. Relying on the stirring effect, the working performance of the concrete can be greatly improved, and the quality of concrete pouring and the appearance quality of the concrete can be improved; even if the concrete stays in the discharging hopper for a slightly longer time or the slump of the concrete is smaller, very good discharging effect can be achieved through the stirring during discharging, reducing the non-production loss of the concrete; it can improve the workability of the concrete, shorten the concrete discharging time and optimize the pouring process.
[0021] The above are all the preferred embodiments of the present invention. The protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
