[0002] Bucket elevators are suitable for conveying powdery, granular, and small block materials with little or no abrasiveness. They have significant advantages such as large conveying capacity, high lifting height, stable and reliable operation, and long service life. Lifting mechanisms are required in the casting production process.

[0003] In response, Chinese patent application number CN202121565165.5 discloses a dust removal device for a bucket elevator in casting production. The device includes a housing with two rotating rollers inside, connected by a belt drive. A first dust removal mechanism is fixedly installed at the bottom of the inner wall of the housing. This mechanism includes two bearing seats symmetrically installed at the bottom of the inner wall of the housing. The drive motor is fixedly installed on the right side of the housing. A rotating rod is movably connected within each bearing seat, and the top of the rotating rod passes through the bearing seat and extends to its exterior, where a fan blade is fixedly connected. This dust removal device for a bucket elevator in casting production has a reasonable structural design and is easy to use. It can effectively clean materials that have fallen and adhered to the inside and outside of the belt, thus preventing belt slippage, improving lifting efficiency, and reducing damage to the bucket elevator to a certain extent, meeting multiple needs.

[0004] The device prevents swept dust from falling onto the first dust removal mechanism by setting up a dustproof net. However, the dustproof net cannot be cleaned, causing dust to accumulate on it, which affects the ventilation effect of the net and thus the effectiveness of the device.

[0005] Therefore, in order to solve the above problems, a cooling lifting mechanism for castings is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a cooling and lifting mechanism for castings, in order to solve the problem mentioned in the background art that the prior art device can prevent the swept dust from falling onto the first dust removal mechanism by setting a dust screen, but the dust screen cannot be cleaned, causing dust to accumulate on the dust screen, which affects the ventilation effect of the dust screen and thus affects the use effect of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling and lifting mechanism for castings, comprising: a housing, a rotating shaft installed on the inner side of the housing, a transmission belt sleeved on the outer side of the rotating shaft, an air outlet on the right side wall of the housing, an air inlet on the top surface of the housing, and a fan assembly installed at the bottom inner side of the housing;

[0008] The bottom of the inner wall of the box is provided with a sliding groove, and the right side wall of the box is provided with an installation groove;

[0009] A filter structure is installed inside the housing. The filter structure includes a support frame, which is slidably installed inside the mounting groove. A handle is fixedly connected to the right side wall of the support frame. A filter screen is installed inside the top surface of the support frame. A movable plate is slidably installed inside the slide groove. A cleaning plate is fixedly connected to the bottom end of the movable plate. A guide post is fixedly installed inside the slide groove. A spring is fixedly connected to the right side wall of the movable plate.

[0010] Preferably, the slide, mounting groove and air outlet are arranged sequentially from top to bottom.

[0011] Preferably, the top surface of the filter screen is fitted to the top wall of the mounting groove, and the bottom surface of the support frame is fitted to the bottom surface of the mounting groove.

[0012] Preferably, the bottom end of the movable plate is located inside the filter screen, and the bottom surface of the cleaning plate is in contact with the top surface of the filter screen.

[0013] Preferably, the guide post passes through the movable plate, the spring is sleeved on the outside of the guide post, and one end of the spring is fixedly connected to the inner wall of the slide groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cleaning plate of this utility model can move back and forth, and can push the movable plate during the transmission of the transmission belt, so as to drive the cleaning plate to push the dust in the filter screen, so that the dust is located on both sides of the top surface of the filter screen, thereby keeping the center of the top surface of the filter screen clean, ensuring the ventilation effect of the filter screen, ensuring the air circulation effect in the filter screen, and improving the use effect of the device.

[0015] This invention, through the inclusion of a filter structure and the activation of the fan assembly, blows heat from inside the chamber out through the air outlet, creating negative pressure inside the chamber. This allows cooler air from outside the chamber to enter through the air inlet, cooling the castings being lifted and conveyed inside. Furthermore, the airflow within the chamber carries away dust from the casting surface, allowing it to flow downwards. The filter screen filters out this dust, and the air is discharged through the air outlet. During operation, the drive belt contacts the right side wall of the movable plate, pushing it and causing it to slide to the left along the guide post within the groove. This movement stretches the spring, and the movable plate further drives... The cleaning plate moves to the left inside the filter screen, pushing the dust in the center of the top surface of the filter screen to the left. When the drive belt separates from the movable plate, the movable plate loses its pushing force and resets under the elastic action of the spring. The movable plate then moves to the right, pushing some dust from the center of the top surface of the filter screen to the right side, keeping the center of the top surface of the filter screen clean, ensuring airflow, and improving dust filtration. After finishing, pulling the support frame to the right causes the filter screen to lose its support and descend into the mounting slot. The cleaning plate then moves upward from inside the filter screen. At this point, pulling the filter screen to the right allows for easy and uniform cleaning of the dust inside the filter screen, keeping the filter screen clean and ensuring a good user experience.

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.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] The housing 1, rotating shaft 11, transmission belt 12 and fan assembly 17 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] A cooling and lifting mechanism for castings includes: a housing 1, a rotating shaft 11 installed on the inner side of the housing 1, a transmission belt 12 sleeved on the outer side of the rotating shaft 11, an air outlet 15 opened on the right side wall of the housing 1, an air inlet 16 opened on the top surface of the housing 1, and a fan assembly 17 installed on the bottom inner side of the housing 1.

[0025] A sliding groove 13 is provided at the bottom of the inner wall of the box 1, and an installation groove 14 is provided on the right side wall of the box 1.

[0026] A filter structure 2 is installed inside the housing 1. The filter structure 2 includes a support frame 21, which is slidably installed inside the mounting groove 14. A handle 22 is fixedly connected to the right side wall of the support frame 21. A filter screen 23 is installed inside the top surface of the support frame 21. A movable plate 24 is slidably installed inside the slide groove 13. A cleaning plate 25 is fixedly connected to the bottom end of the movable plate 24. A guide post 26 is fixedly installed inside the slide groove 13. A spring 27 is fixedly connected to the right side wall of the movable plate 24. The cleaning plate 25 can reciprocate and can push the movable plate 24 during the transmission of the transmission belt 12, so that the cleaning plate 25 pushes the dust in the filter screen 23, so that the dust is located on both sides of the top surface of the filter screen 23, thereby keeping the center of the top surface of the filter screen 23 clean. This ensures the ventilation effect of the filter screen 23, ensures the air circulation effect in the filter screen 23, and improves the use effect of the device.

[0027] Furthermore, the slide 13, mounting groove 14 and air outlet 15 are arranged sequentially from top to bottom. The movable plate 24 installed in the slide 13 can drive the cleaning plate 25 to move inside the filter screen 23 installed in the mounting groove 14.

[0028] Furthermore, the top surface of the filter screen 23 is in contact with the top wall of the mounting groove 14, and the bottom surface of the support frame 21 is in contact with the bottom surface of the mounting groove 14. The support frame 21 can support the filter screen 23 from below, so that the lower end of the movable plate 24 is located inside the filter screen 23, which can drive the cleaning plate 25 to clean the inside of the filter screen 23.

[0029] Furthermore, the bottom of the movable plate 24 is located inside the filter screen 23, and the bottom surface of the cleaning plate 25 is in contact with the top surface of the filter screen 23. The movement of the cleaning plate 25 can clean the dust inside the filter screen 23, ensuring the ventilation effect of the filter screen 23.

[0030] Furthermore, the guide post 26 penetrates the movable plate 24, and the spring 27 is sleeved on the outside of the guide post 26. One end of the spring 27 is fixedly connected to the inner wall of the slide groove 13. The guide post 26 guides and limits the movement of the movable plate 24, and the spring 27 provides power for the movable plate 24 to reset on the filter screen 23.

[0031] Working principle: When in use, starting the rotating shaft 11 can drive the transmission belt 12 to lift and transport the castings;

[0032] When the fan assembly 17 is turned on, the heat inside the housing 1 can be blown out through the air outlet 15, creating a negative pressure inside the housing 1. This allows the low-temperature air outside the housing 1 to enter the housing 1 through the air inlet 16, which can cool down the castings being lifted and conveyed inside the housing 1. The airflow inside the housing 1 will also carry away the dust on the surface of the castings, allowing the dust to flow downwards along with the airflow inside the housing 1. The filter screen 23 can filter the dust in the air, and the air can be discharged through the air outlet 15.

[0033] When the drive belt 12 is in operation, it can contact the right side wall of the movable plate 24 and push the movable plate 24, causing the movable plate 24 to slide to the left in the slide groove 13 via the guide post 26. When the movable plate 24 moves, it will stretch the spring 27, and the movable plate 24 will drive the cleaning plate 25 to move to the left in the filter screen 23, which can push the dust in the center of the top surface of the filter screen 23 to the left. When the drive belt 12 separates from the movable plate 24, the movable plate 24 loses its pushing force and will be reset under the elastic action of the spring 27. The movable plate 24 will then move to the right, which can push some dust from the center of the top surface of the filter screen 23 to the right side of the top surface of the filter screen 23, so as to keep the center of the top surface of the filter screen 23 clean, ensure the ventilation effect, and improve the filtration effect of dust.

[0034] After completion, pull the support frame 21 to the right, and the filter screen 23 will lose its support and descend into the mounting slot 14. The cleaning plate 25 will then move upward from inside the filter screen 23. At this time, pull the filter screen 23 to the right to pull it out, which makes it easy to clean the dust inside the filter screen 23 in a unified manner, keep the filter screen 23 clean, and ensure the subsequent user experience of the filter screen 23.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way.
