Technical Field

[0001] This utility model belongs to the technical field of screw conveyors, specifically relating to a screw conveyor for a mixing grouting equipment. Background Technology

[0002] Mixed grouting equipment is used for spraying grout after mixing concrete during construction. When using mixed grouting equipment, materials need to be fed into the feed box. Usually, materials are fed by a screw conveyor. The existing screw conveyor is installed on the mixed grouting equipment for feeding materials. The screw conveyor uses a motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It is convenient to place the screw conveyor on the mixed grouting equipment for efficient conveying.

[0003] When existing screw conveyors are installed on mixing grouting equipment, the material is fed into the conveying pipe through the feed hopper and transported by the screw conveyor. When too much material is conveyed at once, small hard materials are easily squeezed onto the inner surface of the conveying pipe under the operation of the screw conveyor. The pressure on the inner surface of the conveying pipe for a long time can cause deformation, and in severe cases, damage and high replacement costs. This affects the protective effect of the screw conveyor on the inner surface of the conveying pipe when it is installed on the mixing grouting equipment. To address this issue, this utility model proposes a screw conveyor for mixing grouting equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a screw conveyor for a mixed grouting equipment, in order to solve the problem mentioned in the background art that when a screw conveyor is installed on a mixed grouting equipment, if too much material is conveyed at once, small hard materials are easily squeezed onto the inner surface of the conveying pipe under the operation of the screw conveyor. Long-term squeezing of the inner surface of the conveying pipe can easily cause deformation of the inner surface, and in severe cases, damage and high replacement costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw conveyor for a grouting equipment, comprising a screw conveyor body, the screw conveyor body including a support frame, a conveying pipe fixed to one side of the support frame by mounting bolts, a feed hopper fixedly installed on the upper surface of the bottom end of the conveying pipe, a discharge port installed at the bottom of the top end of the conveying pipe, a screw conveyor driven by a main motor inside the conveying pipe, and the screw conveyor body further comprising:

[0006] The elastic protection mechanism includes an elastic protection component disposed on the inner surface of the conveying pipe, an engaging component disposed on the outer surface of the elastic protection component, and a fixing mounting component disposed on both sides of the elastic protection component.

[0007] The crushing mechanism includes two sets of crushing components disposed inside the feed hopper, and the ends of the crushing components are provided with drive components.

[0008] Preferably, the elastic protective component includes an integrally formed mounting groove on the inner surface of the delivery pipe, and the inner surface of the mounting groove is provided with four elastic protective plates.

[0009] Preferably, the elastic guard plate has an arc-shaped structure, and the four elastic guard plates match the inner surface structure of the mounting groove.

[0010] Preferably, the engaging assembly includes three engaging bodies integrally disposed on the outer surface of the elastic guard plate, and the inner surface of the mounting groove is provided with a slot, and the engaging bodies engage with the slot.

[0011] Preferably, the fixed installation component includes grooves equidistantly opened on both sides of the elastic guard plate, a fixing bolt is provided inside the groove, an internal threaded hole is opened inside the installation groove, and the end of the fixing bolt is threadedly connected to the internal thread of the internal threaded hole.

[0012] Preferably, the crushing assembly includes two crushing rollers mounted inside the feed hopper via bearings, and the two crushing rollers are arranged symmetrically.

[0013] Preferably, the drive assembly includes a drive groove formed on one side of the feed hopper, a gear is installed inside the drive groove at the end of the crushing roller, and two gears mesh with each other, and an auxiliary motor is fixed at the end of the crushing roller on the surface of the feed hopper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing an elastic protection mechanism, four elastic guard plates can be fixed and closed on the inner surface of the conveying pipe for protection. When the screw conveyor is running, if too much material is fed into the conveying pipe at one time, the small hard materials mixed inside will be directly squeezed onto the surface of the elastic guard plates. The elastic guard plates will deform to buffer the impact, preventing damage to the inner surface of the conveying pipe from compression. This provides effective protection and prevents long-term compression damage to the elastic guard plates. Conversely, if the operation is reversed, a single elastic guard plate can be disassembled and replaced, resulting in low replacement costs and improving the protection effect of the screw conveyor body on the inner surface of the conveying pipe when it is installed in a mixing grouting equipment.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a screw conveyor for a grouting equipment, comprising a screw conveyor body 100, a support 102, a conveying pipe 101 fixed to one side of the support 102 by mounting bolts, a feed hopper 103 fixedly installed on the upper surface of the bottom end of the conveying pipe 101, a discharge port 104 installed at the bottom of the top end of the conveying pipe 101, and a screw conveyor 105 driven by a main motor inside the conveying pipe 101. The screw conveyor body 100 is also equipped with:

[0026] The elastic protection mechanism includes an elastic protection component disposed on the inner surface of the conveying pipe 101, an engaging component disposed on the outer surface of the elastic protection component, and a fixing mounting component disposed on both sides of the elastic protection component. When the screw conveyor body 100 is conveying material, and a large amount of material is fed into the conveying pipe 101 at one time, the small hard material mixed inside is directly squeezed onto the surface of the elastic guard plate 1011. The deformation of the elastic guard plate 1011 provides buffering, making it less likely to cause damage to the inner surface of the conveying pipe 101 by compression. This provides effective protection, and the replacement cost is low when damaged.

[0027] In order to facilitate the protection of the inner surface of the conveying pipe 101 from compression by means of the elastic protective component, in this embodiment, preferably, the elastic protective component includes an installation groove 1012 integrally formed on the inner surface of the conveying pipe 101. The inner surface of the installation groove 1012 is provided with four elastic guard plates 1011, and the four elastic guard plates 1011 match the inner surface structure of the installation groove 1012. After the elastic guard plates 1011 are fixed inside the installation groove 1012, when a large amount of material enters the conveying pipe 101 and is compressed against the inner surface of the conveying pipe 101, the small hard material is directly compressed against the surface of the elastic guard plate 1011 for buffering, and is not easily compressed and damaged.

[0028] In order to facilitate the quick snap-fit ​​installation of the elastic guard plate 1011 by means of the snap-fit ​​assembly, in this embodiment, preferably, the snap-fit ​​assembly includes three snap-fit ​​bodies 1015 integrally disposed on the outer surface of the elastic guard plate 1011, and the inner surface of the mounting groove 1012 is provided with a snap-fit ​​groove 1014, and the snap-fit ​​bodies 1015 are snap-fitted and installed with the snap-fit ​​groove 1014. The snap-fit ​​bodies 1015 are snapped into the inside of the snap-fit ​​groove 1014 to snap the elastic guard plate 1011 onto the inner surface of the delivery pipe 101, which facilitates snap-fit ​​installation and fixation.

[0029] To facilitate the secure installation and reinforcement of the elastic guard plate 1011 using a fixed mounting assembly, and to ensure more stable use, in this embodiment, preferably, the fixed mounting assembly includes grooves 1016 equidistantly spaced on both sides of the elastic guard plate 1011. A fixing bolt 1013 is provided inside the groove 1016. An internally threaded hole is provided inside the mounting groove 1012, and the end of the fixing bolt 1013 is threaded into the internally threaded hole. After the elastic guard plate 1011 is secured inside the mounting groove 1012, the fixing bolt 1013, located inside the groove 1016, is rotated to embed into the internally threaded hole, thus reinforcing and stabilizing the elastic guard plate 1011 for use.

[0030] The crushing mechanism includes two sets of crushing components disposed inside the feed hopper 103. The ends of the crushing components are provided with drive components, which can feed the screw conveyor body 100 into the feed hopper 103 during use. The crushing mechanism crushes the large hard materials entering the feed hopper 103, which facilitates the crushing of large materials during feeding and prevents them from entering the conveying pipe 101 and the screw conveyor 105 and causing conveying damage.

[0031] In order to facilitate the crushing of large hard materials mixed inside the feed hopper 103 when the material enters the feed hopper 103, in this embodiment, preferably, the crushing assembly includes two crushing rollers 1034 mounted inside the feed hopper 103 by bearings, and the two crushing rollers 1034 are symmetrically arranged. When the material enters the feed hopper 103, the large hard materials mixed inside can be crushed by the two crushing rollers 1034 running in opposite directions, which can efficiently transport the material.

[0032] In order to facilitate the crushing process by driving the two crushing rollers 1034 to run in opposite directions through the drive assembly, in this embodiment, preferably, the drive assembly includes a drive groove 1032 opened on one side of the feed hopper 103. The end of the crushing roller 1034 is located inside the drive groove 1032 and a gear 1033 is installed, and the two gears 1033 mesh with each other. The end of the crushing roller 1034 is located on the surface of the feed hopper 103 and an auxiliary motor 1031 is fixed thereon. The auxiliary motor 1031 can be turned to drive the crushing roller 1034 and the gear 1033 to rotate. When the two gears 1033 mesh, they drive the two crushing rollers 1034 to run in opposite directions to crush large hard materials.

[0033] The working principle and usage process of this utility model are as follows: When using this type of screw conveyor for mixed grouting equipment, the main body 100 of the screw conveyor is stably placed on one side of the mixed grouting equipment by the bracket 102. The discharge port 104 is aligned with the feed box of the mixed grouting equipment. During operation, the material is injected into the feed hopper 103 and discharged into the conveying pipe 101. The main motor drives the screw conveyor 105 to rotate and transport the material to the top, and then discharges it into the feed box of the mixed grouting equipment through the discharge port 104.

[0034] Then, when the screw conveyor body 100 is running, the auxiliary motor 1031 can be energized to drive the gear 1033 and the crushing roller 1034 to rotate. The two gears 1033 mesh and rotate, causing the two crushing rollers 1034 to rotate in opposite directions. This allows the screw conveyor body 100 to inject material into the feed hopper 103. When large hard objects are mixed inside the material, they are directly crushed by the two crushing rollers 1034 rotating in opposite directions. Smaller materials enter through the gap between the two crushing rollers 1034 into the conveying pipe 101. This facilitates the crushing of large materials during feeding and prevents them from entering the conveying pipe 101 and the screw conveyor 105, which could cause damage during conveying. This improves the convenience of feeding and crushing when the screw conveyor body 100 is used on a mixing and grouting equipment, and enables high-efficiency conveying.

[0035] Finally, when the screw conveyor body 100 is installed before use, the elastic guard plate 1011 can be closed onto the inner surface of the mounting groove 1012 by engaging the clamping body 1015 inside the clamping groove 1014. After the elastic guard plate 1011 is engaged, the fixing bolt 1013 is rotated and inserted into the internal threaded hole to reinforce the installation of the elastic guard plate 1011, thereby fixing and closing the four elastic guard plates 1011 onto the inner surface of the conveying pipe 101 for protection. When the screw conveyor body 100 is running, the conveying pipe... Excessive feeding into the internal part of the screw conveyor 101 causes the small, hard materials mixed inside to be directly squeezed onto the surface of the elastic guard plate 1011. The deformation of the elastic guard plate 1011 provides cushioning, preventing damage to the inner surface of the conveying pipe 101 from compression. This provides effective protection and prevents long-term compression damage to the elastic guard plate 1011. Conversely, the operation only requires disassembling and replacing a single elastic guard plate 1011, resulting in low replacement costs and improving the protection effect of the screw conveyor body 100 on the inner surface of the conveying pipe 101 when it is installed in the mixing and grouting equipment.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
