[0003] However, the following problems exist when the existing resin sand mixer feeding system is in use:

[0004] Due to the different sizes of resin sand mixers, there are differences in the heights of the feeding ports of resin sand mixers. And if the distance between the feeding system of the resin sand mixer and the feeding port of the resin sand mixer is too large, it is easy to cause some materials to fail to enter the feeding port of the resin sand mixer when the materials fall, resulting in a waste of resources. Therefore, in order to make the materials fall stably into the resin sand mixer, the device needs to be convenient to adjust the length of the discharging pipe according to the height of the feeding port of the resin sand mixer. However, the existing resin sand mixer feeding system is not convenient to adjust the length of the discharging pipe according to the height of the feeding port of the resin sand mixer, thus easily affecting the stability of the materials falling into the resin sand mixer.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original resin sand mixer feeding system. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a feeding system for a resin sand mixer, including a bottom plate 1, a brake caster 2, a screw conveyor 3, a support rod 4, a casing 5, a collar 6, a stabilizing rod 7, a pressure plate 8, an anti-slip pad 9, an inner blanking pipe 10, an outer pipe 11, a cardboard 12, a tooth protrusion 13, a positioning frame 14, a limiting mechanism 15, a pull rod 1501, a tooth plate 1502 and a spring 1503. Brake casters 2 are installed at the edge of the lower surface of the bottom plate 1, and a screw conveyor 3 is fixedly arranged on the upper surface of the bottom plate 1. A support rod 4 is fixedly connected to the upper surface of the bottom plate 1 on the side of the screw conveyor 3. A casing 5 is sleeved on the outer wall of the support rod 4. A collar 6 is movably installed on the outer wall of the casing 5. A stabilizing rod 7 is fixedly connected to the outer wall of the collar 6. A pressure plate 8 is fixedly installed at the end of the stabilizing rod 7. An anti-slip pad 9 is bonded to the lower surface of the pressure plate 8. The upper end of the screw conveyor 3 is provided with an inner blanking pipe 10. An outer pipe 11 is sleeved on the outer wall of the inner blanking pipe 10. A cardboard 12 is fixedly arranged on the outer wall of the inner blanking pipe 10 above the outer pipe 11. A tooth protrusion 13 is fixedly installed on the outer wall of the side of the cardboard 12. A positioning frame 14 is fixedly arranged on the upper end outer wall of the outer pipe 11. A limiting mechanism 15 is installed on the inner wall of the end of the positioning frame 14.

[0023] The screw conveyor 3 is fixedly connected to the support rod 4, and the support rod 4 is threadedly connected to the sleeve 5. Moreover, the sleeve 5 and the collar 6 form a rotating structure, which facilitates improving the stability of the screw conveyor 3 through the support rod 4 and enables the user to rotate the sleeve 5 so that the sleeve 5 moves along the support rod 4, thereby driving the collar 6 to move.

[0024] The stabilizing rod 7 is slidably arranged on the bottom plate 1, and the inner blanking pipe 10 is slidably connected to the outer pipe 11. This facilitates the movement of the collar 6, causing the stabilizing rod 7 to slide relative to the bottom plate 1, thereby driving the pressing plate 8 to make the anti-slip pad 9 closely adhere to the ground, further improving the stability of the device during operation. It also facilitates the sliding of the outer pipe 11 relative to the inner blanking pipe 10, thereby adjusting the length of the blanking pipe of the device.

[0025] The clamping plate 12 is slidably connected to the positioning frame 14, and the cross-sectional shape of the clamping plate 12 is set as an "L" shape, which facilitates the outer pipe 11 to drive the positioning frame 14 to slide relative to the clamping plate 12 when the outer pipe 11 moves.

[0026] The limiting mechanism 15 includes a pull rod 1501, a toothed plate 1502, and a spring 1503. The pull rod 1501 is movably installed on the inner wall of the end of the positioning frame 14, and the end of the pull rod 1501 is fixedly connected to the toothed plate 1502. Moreover, the outer side wall of the toothed plate 1502 is connected to the positioning frame 14 through the spring 1503, which facilitates limiting the outer pipe 11 through the limiting mechanism 15 to make the outer pipe 11 and the inner blanking pipe 10 in a relatively stable state, and elastically supporting the toothed plate 1502 through the spring 1503.

[0027] Both the pull rod 1501 and the toothed plate 1502 are slidably connected to the positioning frame 14, and the toothed plate 1502 meshes with the tooth projection 13. This facilitates the pull rod 1501 and the toothed plate 1502 to move relative to the positioning frame 14 simultaneously when the user pulls the pull rod 1501, thereby causing the toothed plate 1502 to disengage from the tooth projection 13, and further facilitating the user to move the outer pipe 11.

[0028] Working principle: When using this resin sand mixer feeding system, first, as Figures 1 - 2 shown, the user pushes the device to move to the working position through the brake casters 2. Then the user rotates the sleeve 5. Next, the sleeve 5 moves along the support rod 4. Subsequently, the sleeve 5 drives the collar 6 to move. Then the collar 6 drives the stabilizing rod 7 to slide relative to the bottom plate 1. Next, the stabilizing rod 7 drives the pressing plate 8 to move, causing the pressing plate 8 to drive the anti-slip pad 9 to closely adhere to the ground, thereby improving the stability of the device. Then, as Figure 1 and Figures 3 - 5As shown, the user adjusts the length of the blanking pipe of the feeding system according to the height of the feeding port of the resin sand mixer. At this time, the user pulls the pull rod 1501. Then, the pull rod 1501 and the toothed plate 1502 slide relative to the positioning frame 14 at the same time, and the toothed plate 1502 compresses the spring 1503 and deforms. Next, the toothed plate 1502 disengages from the tooth projection 13. Subsequently, the user pulls the outer pipe 11 to slide relative to the inner blanking pipe 10. And as the outer pipe 11 moves, the outer pipe 11 drives the positioning frame 14 to slide relative to the clamping plate 12. And as the outer pipe 11 moves, the length of the blanking pipe of the feeding system is adjusted. When the length of the blanking pipe is adjusted to the required length, the user releases the pull rod 1501. At this time, the spring 1503 resets and pushes the toothed plate 1502 to move so that the toothed plate 1502 meshes with the tooth projection 13, thereby limiting the outer pipe 11 to complete the adjustment of the length of the blanking pipe. Therefore, the device is convenient for adjusting the length of the blanking pipe according to the height of the feeding port of the resin sand mixer, thereby ensuring the stability of the material falling into the resin sand mixer. Then, the user pours the material into the screw conveyor 3, and then conveys the material to the resin sand mixer through the screw conveyor 3, the inner blanking pipe 10 and the outer pipe 11.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
