[0023] 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 utility model. 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.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A raw material conveying rack for stress pipeline grouting production, comprising:

[0026] The main body includes a support frame 1, a conveying pipe 11 is fixedly connected to the surface of the support frame 1, one end of the conveying pipe 11 is fixedly connected to a driving component 12 and a discharge port 15, the other end of the conveying pipe 11 is fixedly connected to a feed port 14, and a spiral blade 13 is arranged inside the conveying pipe 11. During the process of grouting production of the stress pipe, the raw material enters the conveying pipe 11 from the feed port 14, and under the action of the motor in the driving component 12, the spiral blade 13 rotates to convey the raw material along the conveying pipe 11 to the discharge port 15 for discharge, so as to achieve a conveying effect;

[0027] The quantity control mechanism includes a partition 2, which is movably connected to the surface of the feed port 14. A movable groove 21 is provided on the surface of the feed port 14. A support plate 22 is fixedly connected to the inner surface of the feed port 14. A mounting plate 23 is fixedly connected to the outer surface of the feed port 14. A limiting hole 24 is provided on the surface of the mounting plate 23. A mounting bin 25 is fixedly connected to the surface of the partition 2. A through hole 26 is provided on the surface of the mounting bin 25. A supporting spring 27 and a limiting plate 28 are movably connected inside the mounting bin 25. A protrusion 29 is fixedly connected to the surface of the limiting plate 28. The partition 2 is used to control the amount of raw materials entering the conveying pipe 11 from the feed port 14 to avoid blockage caused by excessive input at one time. The limiting holes 24 are distributed in a linear array on the mounting plate 23.

[0028] Furthermore, the partition 2 is slidably connected to the surface of the movable groove 21 and the support plate 22. There are two groups of support plates 22. The two groups of support plates 22 are arranged on both sides of the feed port 14. The number of support plates 22 in each group is two. The size of the limiting hole 24 is larger than the size of the protrusion 29. Under the action of the support plate 22 and the movable groove 21, the partition 2 is supported so that it can move along its surface to control the amount of raw materials entering.

[0029] Furthermore, the mounting bin 25 is closely connected to the surface of the mounting plate 23, the diameter of the through hole 26 is the same as the diameter of the limiting hole 24, one end of the support spring 27 is fixedly connected to the inner surface of the mounting bin 25, and the other end of the support spring 27 is fixedly connected to the surface of the limiting plate 28. The movement of the partition 2 is driven by the movement of the mounting bin 25, and under the action of the support spring 27, a supporting force is applied to the limiting plate 28, thereby driving the movement of the limiting plate 28 and the protrusion 29.

[0030] Furthermore, the limit plate 28 is abutted against the inner surface of the mounting bin 25, the protrusion 29 passes through the through hole 26 and is connected to the surface of the mounting bin 25, and the protrusion 29 is engaged with the surface of the limit hole 24. Under the push of the support spring 27, the limit plate 28 slides on the inner surface of the mounting bin 25 and finally abuts against it, so as to achieve the effect of passing the protrusion 29 through the through hole 26 and engaging with the mounting plate 23, thereby achieving the control and adjustment of the opening size of the feed port 14 by the partition 2.

[0031] Furthermore, an extension mechanism is provided on the surface of the discharge port 15, and the extension mechanism includes a first extension plate 3, which is fitted and connected to the surface of the discharge port 15, and a second extension plate 31 is fitted and connected to the surface of the discharge port 15, and a mounting groove 32 is provided on the surface of the first extension plate 3, and a fixing plate 33 is fixedly connected to the surface of the discharge port 15, and a limiting rod 34 is fixedly connected to the surface of the first extension plate 3, and a clamping plate 35 is fixedly connected to the surface of the second extension plate 31. The length of the discharge port 15 can be extended by the first extension plate 3 and the second extension plate 31 to avoid splashing caused by direct falling of raw materials when discharged, and the size of the first extension plate 3 is the same as the size of the second extension plate 31, and the cross-sections of both are "U"-shaped.

[0032] Furthermore, two groups of mounting grooves 32 and fixing plates 33 are provided, one group of mounting grooves 32 is opened on the surface of the first extension plate 3, and the other group of mounting grooves 32 is opened on the surface of the second extension plate 31. The two groups of fixing plates 33 are arranged on both sides of the discharge port 15, and the fixing plates 33 are snap-connected to the surfaces of the mounting grooves 32. Under the snap-connection between the fixing plates 33 and the mounting grooves 32, the effect of installing the first extension plate 3 and the second extension plate 31 on the discharge port 15 is achieved, and the cross-section of the fixing plate 33 is "L"-shaped.

[0033] Furthermore, two groups of limit rods 34 and snap plates 35 are provided, the two groups of limit rods 34 are installed on both sides of the first extension plate 3, and the two groups of snap plates 35 are installed on both sides of the second extension plate 31. One side of the snap plate 35 is fixedly connected to the surface of the second extension plate 31, and the other side of the snap plate 35 is snap-connected to the surface of the limit rod 34. The first extension plate 3 and the second extension plate 31 can be connected and fixed by the connection between the limit rod 34 and the snap plate 35, and then the two can be spliced ​​for use. At the same time, the cross-section of the limit rod 34 is "C"-shaped, and the cross-section of the snap plate 35 is "Z"-shaped.

[0034] Working principle: When the raw material is put into the feed port 14, the protrusion 29 is first pressed into the installation bin 25 so that it passes through the through hole 26 and is placed in the installation bin 25, and then the limit plate 28 slides along the inner surface of the installation bin 25, and the support spring 27 is in a compressed state. Then the installation bin 25 is pulled and the partition 2 is driven to move together, so that the partition 2 slides along the movable groove 21 and the support plate 22. When the partition 2 controls the amount of raw material to meet the requirements, it stops moving. At this time, the limit plate 28 is re-adapted to the inner surface of the installation bin 25 under the action of the supporting force exerted by the support spring 27, and the protrusion 29 passes through the through hole 26 again and engages with the limit hole 24 there.

[0035] When the raw material is discharged from the discharge port 15, the first extension plate 3 and the second extension plate 31 are first installed on both sides of the discharge port 15 respectively, so that the installation groove 32 passes through the fixed plate 33 and engages with it, and at the same time, the clamping plates 35 on both sides are pressed inward to make them pass through the limiting rod 34. After loosening, the clamping plates 35 and the limiting rod 34 achieve a clamping effect, and then the first extension plate 3 and the second extension plate 31 abut against each other to achieve a splicing effect. After the raw material is discharged from the discharge port 15, it will fall under the protection of the first extension plate 3 and the second extension plate 31.
