Technical Field

[0001] The utility model belongs to the technical field of powder conveying, and in particular relates to a laser cladding powder conveying device. Background Art

[0002] Laser cladding powder is a raw material used for laser cladding work. Laser cladding is a technology that uses laser to heat and melt the fallen powder, clad it on the surface of the workpiece, and make it solidify quickly, forming a surface coating technology with extremely low dilution and metallurgical bonding with the base material.

[0035] The dredging structure is symmetrically arranged at the left and right ends of the conveying rod 4 and extends to the inside of the loading port 2 and the discharge port 3.

[0036] In the embodiment of the utility model, when in use, the conveying rod 4 in the middle of the conveying cylinder 1 is started to rotate, thereby driving the conveying blade 5 to push the powder entering from the feeding port 2 to the discharge port 3 on the right side for discharge, and at the same time driving the dredging structure to work, dredging the inside of the feeding port 2 and the discharge port 3;

[0037] By arranging a dredging structure on the conveying rod 4 and extending it to the feeding port 2 and the discharge port 3 on the left and right sides of the conveying cylinder 1, the power of the conveying rod 4 is utilized to break up the powder in the feeding port 2 and the discharge port 3, thereby preventing the powder from clogging the feeding port 2 and the discharge port 3 due to residual moisture.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the utility model, a drying structure is also provided on the top of the conveying cylinder 1, and the drying structure includes a heating rod 6, an exhaust plate 18 and exhaust holes 17. The heating rod 6 is fixedly installed in the middle of the right end of the conveying cylinder 1 and extends to the inside of the conveying rod 4.

The exhaust plate 18 is fixedly installed on the top of the conveying cylinder 1, and the exhaust holes 17 are arranged in an array at the bottom of the exhaust plate 18 and extend to the top of the conveying cylinder 1. An exhaust pipe 19 is fixedly installed on the right side of the exhaust plate 18, and a dehumidification pump 20 is fixedly installed on the right side of the conveying cylinder 1 and is fixedly connected to the bottom of the exhaust pipe 19.

[0039] In the embodiment of the utility model, when in use, the heating rod 6 is started, so that the temperature of the conveying rod 4 and the conveying blade 5 is increased, and then the temperature in the conveying cylinder 1 is increased, so that the residual moisture in the powder entering therein is evaporated, and it moves to the top of the conveying cylinder 1, and the dehumidification pump 20 is started to extract the moisture at the top into the exhaust plate 18 through the exhaust hole 17, and then it is extracted through the exhaust pipe 19 and then discharged;

[0040] By providing a drying structure, the powder in the conveying cylinder 1 becomes dry, thereby facilitating the subsequent cladding work.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the utility model, the dredging structure includes a transmission unit, a dredging rod 15, a rotating rod 16 and a limiting rod 14, the transmission unit array is arranged on the surface of the conveying rod 4, the rotating rod 16 is fixedly installed on the top of the transmission unit and extends to the inside of the delivery port 2 and the discharge port 3, the dredging rods 15 are arranged in a circular array on the surface of the rotating rod 16, the surfaces of the delivery port 2 and the discharge port 3 are provided with limiting grooves 13, the limiting rods 14 are arranged in a circular array on the surface of the rotating rod 16, and are slidably arranged inside the limiting grooves 13.

[0042] In the embodiment of the utility model, when the conveying cylinder 1 rotates, the rotating rod 16 is driven to rotate through the transmission unit, thereby rotating the dredging rod 15 and the limiting rod 14 to break up the powder inside;

[0043] By setting a limit rod 14 in the limit groove 13, the transmission rod 11 and the slip ring 10 on its surface cannot rotate with the conveying rod 4, so that the transmission unit converts the power of the conveying rod 4 into power of another angle, thereby facilitating the rotation of the rotating rod 16 to rotate and clear the blockage, thereby avoiding the occurrence of blockage.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, as a preferred embodiment of the utility model, the transmission unit includes a limit plate 7 and a transmission rod 11. The limit plates 7 are arranged in a left-right symmetrical array on the surface of the conveying rod 4 and are staggered with the conveying blades 5. A movable groove 8 is opened inside the limit plate 7, and a transmission tooth groove 9 is opened in the inner circumferential array of the limit plate 7. A slip ring 10 is slidably installed on the top of the limit plate 7. The transmission rod 11 is movably inserted in the top of the slip ring 10 and is fixedly connected to the bottom of the rotating rod 16. The bottom of the transmission rod 11 passes through the surface of the slip ring 10 and is fixedly connected to a bevel gear 12. The bevel gear 12 is transmission-connected to the transmission tooth groove 9, and a rotating rod 16 is fixedly installed on the top of the transmission rod 11.

[0045] In the embodiment of the utility model, when the conveying rod 4 rotates, the limit plates 7 at the left and right ends are driven to rotate at the same time, and the bevel gear 12 at the bottom of the transmission rod 11 is driven to rotate through the transmission tooth groove 9, so that the transmission rod 11 is rotated, and the rotating rod 16 is driven to rotate;

[0046] By providing a transmission unit, the power of the conveying rod 4 can be converted into power at another angle, so as to facilitate driving the rotating rod 16 to rotate and dredge, thereby avoiding blockage.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, the surface array of the conveying cylinder 1 is sleeved with a clamping ring 21, the top array of the clamping ring 21 is installed with a fixing screw 22, the bottom of the clamping ring 21 is movably hinged with a support rod 23, and the bottom of the support rod 23 is fixedly installed with a supporting base plate 24.

[0048] In the embodiment of the utility model, when in use, the delivery cylinder 1 is inserted into the clamp ring 21, then fixed with the fixing screw 22, and then connected to the support rod 23 on the top of the support base plate 24;

[0049] By arranging support rods 23 of different heights on the support bottom plate 24, a height difference is formed between the left and right ends of the conveying cylinder 1 when supporting the conveying cylinder 1, thereby facilitating the falling and movement of the powder.

[0050] like Figure 3 As shown, as a preferred embodiment of the present utility model, the conveying rod 4 is configured as a hollow structure, and the inner diameter of the conveying rod 4 is greater than the diameter of the heating rod 6 .

[0051] In the embodiment of the utility model, when in use, by setting the conveying rod 4 as a hollow structure, and the inner diameter of the conveying rod 4 is larger than the diameter of the heating rod 6, it is convenient to insert the heating rod 6 into the conveying rod 4 for heating, and avoid hard contact with the conveying rod 4, which may cause wear thereof.

[0052] like Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment of the utility model, the length of the dredging rod 15 is equal to the radius of the injection port 2 and the discharge port 3, and the dredging rods 15 are arranged in an array with staggered positions.

[0053] In the embodiment of the utility model, when in use, by making the length of the dredging rod 15 equal to the radius of the delivery port 2 and the discharge port 3, and staggering the array of the dredging rods 15, a good dredging effect is achieved on the delivery port 2 and the discharge port 3, thereby avoiding blockage.

[0054] The above embodiment of the utility model provides a laser cladding powder conveying device. When in use, the conveying rod 4 in the middle of the conveying cylinder 1 is started, thereby driving the conveying blade 5 to rotate, and the powder dropped from the high-place delivery port 2 is conveyed to the bottom discharge port 3, and then dropped to a designated place;

[0055] When the conveying rod 4 rotates, the limit plates 7 at the left and right ends are driven to rotate at the same time. However, due to the limitation of the limit rod 14 in the limit groove 13, the transmission rod 11 and the slip ring 10 on its surface cannot rotate with the conveying rod 4. Then, when the limit plate 7 rotates, the bevel gear 12 at the bottom of the transmission rod 11 is driven to rotate through the transmission tooth groove 9, and then the rotating rod 16 in the feeding port 2 and the discharge port 3 is driven to rotate through the top transmission rod 11, and then the dredging rod 15 on its surface is used to scatter and dredge the passing powder, so as to avoid excessive accumulation of powder.

[0056] At the same time, when working, the heating rod 6 is started to increase the temperature of the conveying rod 4 and the conveying blade 5, thereby increasing the temperature in the conveying cylinder 1, so that the residual water in the powder entering therein is evaporated and moves to the top of the conveying cylinder 1;

[0057] At the same time, the dehumidifying pump 20 is started to draw the moisture at the top into the exhaust plate 18 through the exhaust hole 17, and then it is drawn out through the exhaust pipe 19 and then discharged, so that the powder in the conveying cylinder 1 becomes dry, which is convenient for the subsequent cladding work.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
