[0002] Shotcrete machine is a new type of high-efficiency shotcrete machine, which is mainly suitable for 5m*5m section tunnel concrete shotcrete operation. When constructing the surface of a building, a shotcrete machine is needed to carry out concrete wall construction. When in use, the shotcrete machine sprays the concrete mixture directly onto the surface of the building, so that a new concrete wall is formed on the surface of the building to reinforce the surface of the building.

[0003] In the prior art, the feeding mechanism of the shotcrete machine generally uses a spiral conveying pipe to transport materials from the ground to the storage hopper. The spiral conveying relies on the friction between the material and the spiral blade and the material to push the material upward. When the material is small, the friction is insufficient and it is difficult to provide sufficient driving force to overcome gravity and the resistance during the conveying process, resulting in the inability to effectively push the material upward.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 , a feeding mechanism of an energy-saving shotcrete machine, comprising a base 1, a storage hopper 2 is fixedly installed on the top surface of the base 1, two brackets 3 are symmetrically installed on the top surface of the base 1, the two brackets 3 are slidably connected with support plates 7, and multiple support plates 7 are fixedly connected, and multiple fixed plates 11 are commonly installed between the two support plates 7, and a plurality of fixed grooves 14 are symmetrically opened on the bottom surface of the shovel hopper 8, and each fixed plate 11 corresponds to the position of the fixed groove 14. It should be noted that through the fixed connection of multiple support plates 7, one of the support plates 7 is driven to slide, and the other support plate 7 also slides accordingly, and the setting of the fixed plate 11 can provide support force for the shovel hopper 8;

[0022] The bracket 3 drives each support plate 7 to slide through a driving mechanism, and the driving mechanism includes a first motor 4, and the first motor 4 is fixedly installed on the top surface of one of the brackets 3, the output shaft of the first motor 4 passes through the bracket 3 and is connected to a threaded rod 5, and the bottom end of the threaded rod 5 is rotatably connected to the top surface of the base 1, and a sliding column 6 is fixedly installed in the other bracket 3, and a threaded sleeve 10 is fixedly installed on the outside of each support plate 7, and one of the threaded sleeves 10 is threadedly connected to the threaded rod 5, and the other threaded sleeve 10 is slidably connected to the sliding column 6. It should be noted that by starting the first motor 4, the threaded rod 5 is driven to rotate, thereby driving one of the support plates 7 to move, and the other support plate 7 is slid on the sliding column 6, thereby limiting the support plate 7 so that it cannot rotate and can only move linearly;

[0023] A shovel bucket 8 is rotatably connected between multiple support plates 7, and a sweeping impeller 9 is symmetrically rotatably connected in the shovel bucket 8. Through the mutual cooperation of multiple sweeping impellers 9, the material on the ground can be swept into the shovel bucket 8. It is worth mentioning that the sweeping impeller 9 is made of hard material, and a back plate 17 is rotatably connected in the shovel bucket 8. The back plate 17 and the shovel bucket 8 are both connected and rotated through a rotating mechanism. The rotating mechanism includes a drive shaft 13 and a rotating shaft 12, and the two ends of the drive shaft 13 and the rotating shaft 12 are respectively rotatably connected to the side surfaces of the corresponding support plates 7, and the drive shaft 13 is fixedly connected to the bottom plate of the shovel bucket 8, and the rotating shaft 12 is fixedly connected to the back plate 17. The drive shaft 13 and the rotating shaft 12 are connected through a synchronization mechanism. The synchronization mechanism includes two synchronization wheels 15, and the two The synchronous wheels 15 are respectively installed on the rotating shaft 12 and the driving shaft 13. The two synchronous wheels 15 are jointly sleeved with a synchronous belt 16. A second motor 18 is fixedly installed on the side of one of the support plates 7, and the second motor 18 penetrates the support plate 7 and is connected to the driving shaft 13.

Then, through the setting of the synchronous mechanism, the back plate 17 is driven to rotate synchronously, and then the shovel bucket 8 is opened. At this time, the material slides onto the back plate 17 under the action of gravity, and then falls into the storage hopper 2, avoiding incomplete unloading of the material in the shovel bucket 8. At the same time, the material can be guided by the back plate 17 to avoid it falling directly into the storage hopper 2 and causing splashing.

[0024] When the utility model is used, firstly, the base 1 is moved to insert the shovel bucket 8 into the concrete material pile on the bottom surface, and then the sweeping impeller 9 can help the shovel bucket 8 to sweep the concrete into the shovel bucket 8, and then the first motor 4 is started, and the two support plates 7 are driven to move upward through the cooperation of the bracket 3 and the threaded sleeve 10, and the shovel bucket 8 is driven to move upward at the same time;

[0025] When it moves to the top, the second motor 18 can be started, and the driving shaft 13 can be driven to rotate by the second motor 18, so that the shovel bucket 8 can be rotated to introduce materials into the storage hopper 2, and the rotating shaft 12 can be driven by the synchronization mechanism to rotate synchronously, thereby driving the back plate 17 to rotate, and the shovel bucket 8 can be opened. Then, the material slides onto the back plate 17 under the action of gravity, and then falls into the storage hopper 2 to complete the feeding.
