Description

Technical Field

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] See also Figure 1 and Figure 2 , this application provides the following technical solutions:

[0048] A prefabricated concrete block vibrator includes a conveying unit 1 and a vibrating unit 2, wherein the conveying unit 1 is a linear conveying mechanism for conveying a prefabricated block mold filled with materials; the vibrating unit 2 is arranged above the conveying unit 1, and the vibrating end of the vibrating unit 2 is extended toward the conveying unit 1, and can vibrate the material in the prefabricated block mold; the vibrating unit 2 can adopt an existing soft shaft eccentric vibrator. The conveying unit 1 includes a conveyor belt 11 with an annular belt body. When the device is working, the prefabricated block mold is placed on the conveyor belt 11 and is conveyed as the conveyor belt 11 rotates. A roller group 12 is arranged inside the annular range of the conveyor belt 11. The roller group 12 includes a plurality of rollers. The rollers are arranged in an array along the conveying direction of the conveyor belt 11, and the axes of the rollers are perpendicular to the conveying direction of the conveyor belt 11; the upper surface of the roller body of the roller is in contact with the lower surface of the conveyor belt 11.

[0049] Because the overall deadweight of the prefabricated block mold may be relatively large after the material is filled, a simple conveyor belt conveying mechanism or a roller conveyor mechanism is not suitable for use as a conveying unit. The pure conveyor belt conveying mechanism is insufficient for the heavy deadweight mold, which easily leads to the rapid consumption and shortening of the life of the conveying mechanism, especially the conveyor belt part. Although the roller conveying mechanism has sufficient bearing capacity, considering that the production of small prefabricated blocks is basically outdoor work, and there may be a situation where materials overflow the mold during the conveying and vibrating process, in this state, outdoor debris and overflowing materials may affect the use of the pure roller conveying mechanism, and the material may adhere to the surface of the roller body. Therefore, the conveying unit 1 of this scheme adopts a structure in which a conveyor belt 11 and a roller group 12 are used in combination. The conveyor belt 11 is used as the first bearing structure of the mold. On the one hand, it is used to transport the mold. On the other hand, even if materials drip on the conveyor belt 11, it will not affect the lower roller. At the same time, even if the material solidifies on the surface of the conveyor belt 11, it is also convenient for later cleaning. The setting of the roller group 12 can greatly improve the bearing capacity of the conveyor belt 11 through the roller.

[0050] On the basis of the above implementation scheme, the frame 3 of the present vibrator includes a lower frame 31 and an upper frame 32, and the frame 3 is used as a bearing structure for the conveying unit 1 and the vibrating unit 2; the conveying unit 1 is arranged on the lower frame 31, and the upper frame 32 is arranged on the lower frame 31, and the vibrating unit 2 is slidably connected to the upper frame 32. Considering that different prefabricated blocks have different specific mold shapes and the shapes presented after the molds are filled with materials, the positions where the vibrating unit 2 enters the materials during vibration will also be different. This solution provides more vibration angles through the sliding of the vibration unit 2 and the upper frame 32, so as to improve the practicality of the device.

[0051] On the basis of the above implementation scheme, the lower frame 31 includes two parallel horizontal bars, the length direction of which is parallel to the conveying direction of the conveyor belt 11; the two ends of the rollers of the roller group 12 are rotatably connected to the horizontal bars through the roller seats 13; the driving mechanism of the roller group 12 is arranged on the horizontal bars; the roller seats 13 are connected to the roller shafts of the rollers through bearings. A support leg is fixedly arranged on the lower side of each horizontal bar, and a connecting rod is arranged between the two horizontal bars, thereby forming a support structure of the lower frame 31.

[0052] Based on the above implementation scheme, see Figure 3 , the two ends of the conveyor belt 11 are respectively wrapped around a roller of the roller group 12; one of the rollers is used as the active roller to drive the conveyor belt 11 to rotate, and the other is used as the driven roller. The driving mechanism of the conveying unit 1 specifically includes a motor 14 and an active roller 15, and the motor 14 is used as the power source of the conveying unit 1; the active roller 15 is linked with the motor 14 through a synchronous wheel structure, and the active roller 15 is arranged on the outside of the discharge end of the conveyor belt 11; the axis of the active roller 15 is parallel to the axis of the roller, and the active roller 15 is linked with the roller at the end of the conveyor belt 11, and the linkage between the two is also achieved through the synchronous wheel structure.

[0053] In this scheme, on the basis of driving the conveyor belt 11 to rotate, an independent active roller 15 is arranged on the outside of the conveyor belt 11. The active roller 15 can further transport the concrete block mold after it moves out of the conveyor belt 11, so as to facilitate the mold to be transported to the subsequent external mechanism, or to help the staff to move the mold out of the device. At the same time, the independent active roller 15 also provides a power access point for the subsequent structure. By simply modifying the active roller 15, it can also serve as the power input end of the subsequent processing structure.

[0054] On the basis of the above implementation scheme, the upper frame 32 includes a gantry frame 321 and a sliding frame 322. Two gantry frames 321 are arranged in parallel, and their lower ends are fixedly connected to the crossbar of the lower frame 31. A sliding frame 322 is arranged between the two gantry frames 321, and a slide groove with a "T"-shaped cross section is provided on the lower side of the crossbeam on the upper part of the gantry frame 321. The sliding frame 322 is a rectangular frame structure, and a slider is arranged corresponding to the slide groove. The two ends of the sliding frame 322 are slidably connected to the gantry frame 321 through the slider and the slide groove respectively; the length direction of the slide groove is parallel to the length direction of the roller. A fixed position is set on the sliding frame 322 corresponding to the vibrating unit 2, such as Figure 1 As shown, a cylindrical placement cage is arranged on the sliding frame 322, and the vibrator body 21 of the vibrating unit 2 can be placed therein. Through grooves are provided on the peripheral wall of the placement cage for heat dissipation.

[0055] The upper frame 32 further includes a crossbeam 323, which is disposed between the two portal frames 321, and the two ends of the crossbeam 323 are respectively fixedly connected to the upper part of one portal frame 321. The crossbeam 323 is used to improve the overall strength of the upper frame 32.

[0056] On the basis of the above implementation scheme, in addition to the vibrator body 21 set on the sliding frame 322, the vibrating unit 2 also includes a flexible shaft 22 connected to the vibrator body 21, and the flexible shaft 22 extends toward the top of the conveyor belt 11; a vibrating rod is set at the end of the flexible shaft 22 away from the vibrator body 21. The vibrating unit 2 of this scheme is an existing eccentric flexible shaft vibrating structure, and its specific structure is not described in detail in this scheme. By combining with existing equipment, the research and development and manufacturing costs of the device of this scheme can be greatly reduced, and it can be combined with similar vibrating equipment of different specifications according to actual use requirements.

[0057] When in use, it is only necessary to wait for the mold to move to a suitable position on the conveyor belt 11, suspend the movement of the conveyor belt 11, and then the staff only needs to pull the flexible shaft 22 to vibrate the material.

[0058] Based on the above implementation scheme, see Figure 4 The vibration unit 2 also includes a vibration piece 23, which is detachably connected to the vibration rod and is arranged at one end of the vibration rod away from the vibrator body 21. The vibration piece 23 is composed of a connecting part and an annular part. The connecting part is a rod structure, and the connecting part is detachably connected to the vibration rod. The connection form of the two can adopt an existing structure, and there is no specific limitation; the annular part is an annular structure as a whole, and is fixedly connected to the connecting part. The vibration efficiency can be improved by the vibration piece 23. For prefabricated parts with sufficient use space, the vibration piece 23 can be connected for use. Whether the vibration piece 23 is used or not is determined by the staff according to the actual situation.

[0059] Based on the above implementation scheme, see Figure 4The vibrating unit 2 also includes a pull ring 24, which is arranged on the flexible shaft 22. The pull ring 24 includes a connecting portion and a pulling portion. The connecting portion is a cylindrical structure, which is sleeved on the outside of the flexible shaft 22 and can be fixed to the outer wall of the flexible shaft 22 by bolts penetrating the cylindrical wall. The pulling portion is a circular plate structure, which is provided with a plurality of through slots. The through slots are arc-shaped slots, and three or four of them are arranged in a circumferential array.

[0060] Considering the convenience of pulling the flexible shaft 22, if the length of the roller is long, it may be inconvenient for the staff to pull it directly by hand, so a pull ring 24 structure is provided, and a pull rod with a hook body is used, and the pull rod can also be used to hook the slot of the pulling part on one side of the conveyor belt 11, so as to facilitate the control of the flexible shaft. Correspondingly, a handle is provided on the outside of the sliding frame 322 to improve the convenience of the staff's operation.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
