[0035] In actual use, the telescopic shovel 2 can be moved left or right by pressing a button, and is used to shovel and throw the raw materials in the raw material pile 1. The telescopic shovel 2 is driven upward by the spiral lifter 3 and the push-up resetter 4. When it moves to the top, the push-up resetter 4 pushes it in a circular arc direction. At this time, the raw materials naturally slide downward, and then the first motor 8 reverses the telescopic device to reset it; the connecting rod 9 effectively prevents the imbalance of the feeding device caused by uneven road surface. At the same time, the entire feeding device can be moved forward or backward by pressing the button on the push armrest, which can effectively cope with raw materials in different positions. The push armrest can also be used to manually assist its feeding device. The power of the above device comes from the mechanical energy converted by the first motor 8; the raw materials fall onto the conveyor belt 13, and the conveyor belt 13 drives the raw materials to the filter screen 20 in the filter box 21 through the first rotating shaft 15. The raw materials that meet the size standards fall to the bottom and slide to the first mixing box 24 through the first through slot 32, and the raw materials that do not meet the standards are crushed by the crusher 19 on the second rotating shaft 16 and then fall to the bottom, so as to prevent the uneven raw materials from causing the internal structure of the concrete to be substandard. The raw materials that slide into the first mixing box 24 are stirred by the first stirring blade 23 on the third rotating shaft 17 to achieve a uniform ratio. During stirring, the raw materials that slide into the first mixing box 24 can be stored by the baffle 34. Then, after the baffle 34 is opened, the concrete that has been stirred for the first time slides into the second mixing box 26, and the second stirring blade 25 on the fourth rotating shaft 18 in the second mixing box 26 performs the second fine stirring. The power of the above first rotating shaft 15, second rotating shaft 16, third rotating shaft 17, and fourth rotating shaft 18 comes from the mechanical energy converted by the second motor 22.

[0036] When it is necessary to clean the material adhered to the pipe mouth of the conveying pipe 28, the regulating ring 50 is turned to pull the telescopic column 37 to slide along the limit frame 1 through the traction rope 44, and the telescopic column 37 drives the limit slider 39 to squeeze the traction spring 42. After the regulating ring 50 is released, the traction spring 42 rebounds and pushes the limit slider 39 to drive the telescopic column 37 to reset. In this way, the knocking handle 38 is driven by the telescopic column 37 to knock on the conveying pipe 28, and the material adhered to the inner wall of the conveying pipe 28 is shaken off.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
