Detailed Description

The utility model will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 1 and 2, the concrete stirring apparatus provided in this embodiment includes a feeding device 1, a screening device 2, and a stirring device 3.

As shown in fig. 1, the feeding device 1 includes a support 11, a feeding table 12, a feeding hopper 13, a first hydraulic rod 14, a second hydraulic rod 15, a stay 16, and a pulley 17. The support 11 includes a bottom plate 111 disposed on the ground, a vertical plate 112 vertically disposed on the bottom plate 111, and a chute 113 vertically disposed on the vertical plate 112. The loading table 12 is located on a side surface of the riser 112, which requires a smooth surface to facilitate the rolling of the pulley 17 therealong.

One side of the feeding table 12 is provided with a sliding block matched with the sliding groove 113, and the upper end of the feeding table 12 is provided with a feeding hopper 13. The first hydraulic rod 14 is mounted on the vertical plate 112 of the support 11 and is connected to the slide. The feeding table 12 is driven to move up and down relative to the support 11 by the extension and retraction of the first hydraulic rod 14 to adjust the relative position of the feeding hopper 13 relative to the screen 22 of the screening device 2.

One side of the feeding hopper 13 is hinged with the feeding table 12, the other end of the feeding hopper is provided with a second hydraulic rod 15, the second hydraulic rod 15 is connected with the feeding hopper 13 and the feeding table 12, and the sand and stone raw materials are poured from the feeding hopper 13 to the screen 22 through the expansion and contraction of the second hydraulic rod 15.

The stay bar 16 is fixed at the bottom of the loading table 12 in a diagonal manner, and a pulley 17 capable of contacting with the surface of the vertical plate 112 is arranged at the tail end of the stay bar 16. The pulley 17 plays a guiding role in the up-and-down movement process of the feeding table 12, and ensures the stability in the up-and-down movement process. The stay bar 16 and the feeding table 12 form a triangle.

As shown in fig. 2, the screening device 2 comprises a frame 21, a screen 22, a conveyor belt 23, a drive motor 24, an eccentric shaft 25, a spindle 26, a transmission assembly 27, an extension rod 28 and a buffer assembly 29. The support 21 is a frame structure formed by interconnecting a plurality of vertical rods, cross rods and diagonal rods. In this embodiment, the number of uprights is four, forming a structure for mounting the screen 22. The top of the support 21 is of an inclined structure with one high end and one low end, namely, the height of two vertical rods close to one end of the support 21 is higher than that of two vertical rods at the other end, and the vertical rods with high heights are arranged close to the stirring device 3. The upper end of the support 21 is connected to the screen 22 by a buffer assembly 29 so that the screen 22 is also in an inclined arrangement. The buffer assembly 29 comprises a buffer rod 291 and a buffer spring 292 sleeved outside the buffer rod 291, wherein the buffer rod 291 is connected between the support 21 and the screen 22. The structural principle of the buffer assembly 29 is the same as that of a buffer assembly used on an electric bicycle.

The conveyor belt 23 is rotatably mounted on the upright of the support 21 by means of a rotation shaft 26, and is arranged obliquely, with its oblique elevation extending through an extension rod 28 to the outside of the support 21, which outside likewise forms the end of the conveyor belt 23 in the direction of movement, which is connected to the feed opening 31 of the stirring device 3. If the material opening 31 is located above the stirring device 3, the end of the movement direction of the conveyor belt 23 is located above the material opening 31. If the feed opening 31 is located on the side of the stirring device 3, the end of the conveyor belt 23 in the direction of movement extends laterally into the feed opening 31. The inclination of the conveyor belt 23 is smaller than that of the screen 22, and the larger inclination of the screen 22 is beneficial to screening and falling of materials; the small gradient of the conveyor belt 23 facilitates the transport of the material to the stirring device 3 and down.

In this embodiment, the number of the rotating shafts 26 is three, one is arranged on each of the two sets of upright posts, one is arranged on the extension rod 28, and the conveyor belt 23 rotates the three rotating shafts 26. A drive motor 24 is provided at the beginning of the direction of movement of the conveyor belt 23, said drive motor 24 being mounted on a short upright and being in driving connection with a spindle 26 on the upright.

Both ends of the eccentric shaft 25 are rotatably connected with the bracket 21, and the eccentric shaft 25 is in contact with the lower end surface of the screen 22. The transmission assembly 27 includes pulleys mounted on a rotation shaft 26 and an eccentric shaft 25 connected to the driving motor 24, respectively, and a belt connecting the two pulleys. The eccentric shaft 25 is rotated while the conveyor belt 23 is driven to run by the driving motor 24, the eccentric structure of the eccentric shaft 25 pushes the screen 22 to move up and down in the rotating process, and the vibration is generated by matching with the buffer assembly 29, so that sand and stone raw materials placed on the screen 22 are screened. The sieved concrete material falls onto the conveyor belt 23 and then falls into the stirring device 3 along with the conveyor belt 23 for stirring.

In addition, two feeding hoppers 13 may be disposed on the feeding table 12, one of which is used for placing raw materials that do not need to be screened, and the other is used for placing raw materials that need to be screened, and the two feeding hoppers 13 are respectively provided with a second hydraulic rod 15. The feeding device 1 is pushed to the side of the screening device 2, the second hydraulic rod 15 of the feeding hopper 13 needing screening is started, raw materials are poured onto the screen 22, and the feeding hopper 13 is reset. The feeding device 1 is pushed to the side of the stirring device 3, the second hydraulic rod 15 of the feeding hopper 13 which does not need to be screened is started, raw materials are poured into the stirring device 3, and the feeding hopper 13 is reset. The actions are not sequenced, and can be determined according to actual process time. Therefore, the feeding and screening of the concrete raw materials are completed manually, the efficiency of stirring the concrete on the construction site is effectively improved, and a large amount of manpower can be saved.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
