Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a device for facilitating material conveying. Background Technology

[0002] Material handling is a common operation in industrial production, logistics and construction engineering, which involves moving materials from one location to another.

[0003] Therefore, the existing material conveyor, with publication number CN220595962U, includes a lifting mechanism comprising a pair of limiting posts, a lead screw, and a first rotary motor. The pair of limiting posts are symmetrically arranged on both sides of the lead screw. The bottom end of the limiting posts is fixedly connected to the upper end face of the lifting plate. The top end of the limiting posts penetrates through the crossbeam and extends above the crossbeam. The lifting plate is provided with a threaded through hole. The lead screw is threadedly connected to the threaded through hole. The bottom end of the lead screw is connected to the first rotary motor, which drives the lead screw to rotate. The first rotary motor is fixed on the lifting plate. Through the lifting mechanism, the height of the cleaning brush can be adjusted according to the height of the material, expanding the applicable range and making it more flexible and efficient. Furthermore, the moving mechanism drives the cleaning brush to reciprocate for longitudinal brushing.

[0004] In existing technologies, the cleaning brush is positioned directly above the conveyor. Although the height-adjustable cleaning brush improves flexibility, in actual operation, it requires frequent adjustments based on different material heights, increasing the complexity and time cost of operation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-4As shown, a material conveying device includes a conveyor 1. A connecting box 3 is located below the frame of the conveyor 1 at the end of the conveyor belt. Blower hoods 8 are fixedly installed on the top edge of the outer wall of the connecting box 3. Several blower hoods 8 are integrally formed and internally interconnected, with their air outlets facing inwards towards the connecting box 3. A cleaning brush 11, driven by a motor and in contact with the surface of the conveyor belt, is rotatably connected to the connecting box 3 relative to its inner wall. In actual use, after the conveyor belt delivers the material to the designated location, it returns to the starting point via the area below the conveyor 1. During the return journey, as the belt passes above the connecting box 3, the cleaning brush 11 rotates and contacts the belt portion, allowing for immediate surface cleaning of the belt after use. The cleaning brush 11 is set parallel to the width direction of the conveyor 1. A blower 7 is fixedly installed through the bottom of the connecting box 3. The air inlet of the blower 7 is located inside the connecting box 3, and the air outlet of the blower 7 is connected to the air inlet pipe of the blower hood 8. The blower 7 draws the air in the connecting box 3 into the blower hood 8, and then blows it back into the connecting box 3 by the blower hood 8, realizing internal circulation. During the internal circulation process, it can prevent the dust generated by the cleaning brush 11 during cleaning from entering the outside of the connecting box 3. An inclined filter plate 12 is fixedly installed inside the connecting box 3. The filter plate 12 is set to cover the air inlet of the blower 7. The filter plate 12 can be used to achieve dust adsorption on the surface of the filter plate 12 during the internal circulation process, so that the dust is trapped inside the connecting box 3.

[0025] A receiving hopper 2 is movably installed on the outer side of one side of the connecting box 3. The receiving hopper 2 is located below the end of the conveyor frame and is bolted to the frame of the conveyor 1. A scraper 10 is fixedly installed at the top opening of the receiving hopper 2. The top edge of the scraper 10 is slidably connected to the surface of the conveyor belt of the conveyor 1, and the bottom edge of the scraper 10 is in clearance fit with the bottom of the receiving hopper 2. The scraper 10 can be used to scrape off large particles and wet materials adhering to the surface during the belt return process, and these materials fall directly into the receiving hopper 2. In addition, if Figure 1 As shown, the receiving hopper 2 is set to extend beyond the end of the conveyor 1, thus enabling the collection of materials that are not attached to the belt of the conveyor 1.

[0026] Two symmetrically distributed and vertically arranged rails 13 are fixedly installed on the outer wall of the receiving hopper 2 facing the connecting box 3. A horizontally arranged lifting seat 14 is inserted into each rail 13. One side of the connecting box 3 is rotatably connected to the inner wall of the lifting seat 14 and swings vertically. At least two evenly distributed hydraulic rods 9, parallel to the rails 13, are fixedly installed on the outer wall of the receiving hopper 2 facing the connecting box 3. The telescopic ends of the hydraulic rods 9 are fixedly connected to the bottom edge of the lifting seat 14. In actual use, the extension and retraction of the hydraulic rods 9 are used to raise and lower the connecting box 3 by the lifting seat 14, facilitating the adjustment of the distance between the blower hood 8 on the connecting box 3 and the conveyor body 1. Furthermore, to ensure that the blower hood 8 is parallel to the belt movement direction, therefore:

[0027] Electric push rods 4 and connecting plates 5 are fixedly installed on the outer walls of two adjacent sides of the receiving hopper 2 located on the lifting seat 14. The connecting plates 5 and electric push rods 4 on the same side are staggered vertically and distributed from near to far from the connecting box 3. The electric push rods 4 and connecting plates 5 are set parallel to the hydraulic rods 9. A traction line 6 is fixedly installed at the telescopic end of the electric push rod 4, passing through the top edge of the connecting plate 5 on the same side. One end of the traction line 6 is connected to the middle of the same side of the connecting box 3. When the electric push rod 4 extends, the connecting box 3 swings down under the action of gravity and pulls the traction rope, thus realizing the downward swing of the connecting box 3. When the electric push rod 4 retracts, it pulls the traction rope, and the traction rope pulls the connecting box 3 to swing up around the lifting seat 14, thus adjusting the tilt of the connecting box 3.

[0028] The method of using this utility model is as follows: After the conveyor belt of the conveyor 1 finishes conveying the material, when it passes the end of the conveyor 1 for reset, the material remaining on the belt is first scraped off by the scraper 10 of the receiving hopper 2. Then, when it passes above the connecting box 3, it is completely cleaned by contacting the rotating cleaning brush 11. During the cleaning process, the dust that falls off is adsorbed on the surface of the filter plate 12 in the connecting box 3 under the internal circulation formed by the exhaust fan 7 and the blower hood 8.

[0029] The wiring diagrams of the conveyor 1, electric push rod 4, exhaust fan 7, and hydraulic rod 9 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the conveyor 1, electric push rod 4, exhaust fan 7, and hydraulic rod 9 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may use the above-disclosed technical content to make changes or modifications to the framework of equivalent embodiments and apply them to other fields. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
