Description

Technical Field

[0001] This utility model relates to the field of sieving machine technology, specifically to a sieving machine that facilitates the removal of the screen. Background Technology

[0002] Screening machines are a crucial part of the non-metallic mineral product processing. They are used to classify raw materials, intermediate products, or finished products according to particle size, remove impurities, or ensure that the particle size of the products meets the requirements. During continuous screening, the screen directly contacts the material. Especially when processing high-hardness minerals or corrosive materials, the screen can be quickly damaged due to wear, impact, or chemical corrosion. Therefore, screening machines need to replace screens frequently.

[0003] However, replacing the screens in traditional screening machines requires a lot of tools, and the downtime during maintenance and replacement is long, which greatly reduces the working efficiency of the equipment. The screen box has no top cover design, so there is no protective effect. Material splashes out, causing material waste and polluting the working environment. The side panels cannot be opened quickly, and residual material inside the screen box can easily accumulate, causing hygiene problems. Utility Model Content

[0004] The purpose of this invention is to provide a sieving machine that facilitates screen removal, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving machine for easy screen removal, comprising a screen box, with two sets of support seats on the left and right sides of the screen box respectively. A buffer spring is fixedly installed at the top of each support seat, and a movable plate is fixedly installed at the other end of the buffer spring. A rotating shaft is fixedly installed at the top of the movable plate, and the shaft of the rotating shaft is rotatably connected to the surface of the screen box. A circular hole is passed through the center of the screen box, and a main shaft is rotatably connected inside the circular hole. A base is provided between the support seats on one side of the screen box, and a vibration assembly is provided at the top of the base. A slide rail is provided on the inner wall of the screen box, and the inner wall of the slide rail slides... The screen is connected to a screen, and a base plate is fixedly installed at the bottom of the slide rail. An upper discharge pipe is fixedly installed at one end of the screen box, and a lower discharge pipe is fixedly installed at the bottom of the upper discharge pipe. A side plate is provided at the other end of the screen box, and a handle is fixedly installed on one side of the side plate. A hinge is fixedly installed on one side of the side plate and the bottom of the inner wall of the screen box. The side plate and the screen box are rotatably connected by the hinge. Buckles are rotatably installed on both sides of the screen box. A slot is fixedly installed on the surface of the side plate at the position corresponding to the buckle. A cover plate is fixedly installed on the top of the screen box, and a feed inlet is opened on the top of the cover plate. A flip-top assembly is provided on the top of the feed inlet.

[0006] The vibration assembly includes an asynchronous motor, which is fixedly mounted on the top of the base. One end of the output end of the asynchronous motor is fixedly mounted with a coupling, and the other end of the coupling is fixedly mounted with a reducer. An eccentric wheel is fixedly mounted on the output end of the reducer.

[0007] The beneficial effects of this utility model are as follows: pulling down the handle allows the side panel to be opened quickly, directly exposing the inside of the screen box; pulling the groove at the end of the screen allows the screen to slide out easily and be quickly removed, facilitating cleaning and replacement, removing residual material that clogs the pores, maintaining screening efficiency and hygiene; simply pulling and releasing the lever completes the locking and unlocking of the top plate; the openable top plate prevents material from splashing out of the screen box; the open side and top plates also facilitate cleaning and inspection of the inside of the screen box; no complicated tools or disassembly of a large number of parts are required, significantly shortening replacement time, reducing downtime during maintenance, and improving work efficiency.

[0008] To facilitate opening the top plate and cleaning the inside of the screen box:

[0009] The flip-top assembly is further configured such that: a pivot seat is included, a rotating block is rotatably connected to the shaft surface of the pivot seat, a top plate is fixedly connected to one side of the rotating block, a handle is fixedly installed on the top of the top plate, an mounting block is fixedly installed on one side of the top plate, a spring is fixedly installed on one side of the mounting block, an insertion rod is fixedly installed on one side of the spring, and a pull rod is fixedly installed on the surface of the insertion rod.

[0010] By adopting the above technical solution, through the rotational connection between the rotating shaft seat and the rotating block, and with the design of the integrated handle on the top plate, the top cover can be opened with one hand. When the pull rod is released, the spring automatically pushes the plug rod to lock, ensuring that the top plate is vibration-resistant and does not loosen during operation.

[0011] To reduce screen clogging, the material automatically slides towards the discharge port under gravity.

[0012] The screen box is further configured such that it is inclined, and one set of the support bases is higher and the other set is lower.

[0013] By adopting the above technical solution, the inclined screen surface combined with vibration creates a tumbling motion of the material, reducing the efficiency of screen hole clogging.

[0014] To reduce vibration attenuation caused by gaps:

[0015] A further configuration is made whereby one end of the main shaft is fixedly mounted on the rotation center of the eccentric wheel.

[0016] By adopting the above technical solution, the eccentric wheel uses its eccentricity to drive the main shaft to vibrate, which in turn causes the screen box to vibrate.

[0017] To improve the efficiency of screen replacement:

[0018] The screen is further configured such that a frame is fixedly installed around its perimeter, sliding blocks are fixedly installed on the left and right sides of the frame, and a groove is provided at one end of the frame.

[0019] By adopting the above technical solution, the sliding blocks on both sides of the frame are embedded in the side plate guide rail. The screen can be slid out of the guide rail by hooking the groove with a finger, which greatly improves the efficiency of disassembly and assembly.

[0020] To ensure the top plate can fit snugly against the cover plate and will not disengage due to vibration during operation:

[0021] A further configuration is provided: a fixing block is fixedly installed on the surface of the cover plate, and a circular groove is provided at the position of the fixing block corresponding to the insertion rod.

[0022] By adopting the above technical solution, the pull rod is released so that the insertion rod automatically slides into the fixing block and locks under the spring force, reducing the loosening of the top plate during vibration.

[0023] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

A lower discharge pipe 12 is fixedly installed at the bottom of the upper discharge pipe 11. A side plate 13 is provided at the other end of the screen box 1. A handle is fixedly installed on one side of the side plate 13. A hinge is fixedly installed on one side of the side plate 13 and the bottom of the inner wall of the screen box 1. The side plate 13 and the screen box 1 are rotatably connected by the hinge. Buckles 14 are rotatably installed on both sides of the screen box 1. A slot 15 is fixedly installed on the surface of the side plate 13 at the position corresponding to the buckle 14. A cover plate 16 is fixedly installed on the top of the screen box 1. A feed inlet is opened on the top of the cover plate 16. A flip-top assembly 17 is provided on the top of the feed inlet.

[0032] The vibration assembly 7 includes an asynchronous motor 701, which is fixedly mounted on the top of the base. One end of a coupling 702 is fixedly mounted on the output end of the asynchronous motor 701, and a reducer 703 is fixedly mounted on the other end of the coupling 702. An eccentric wheel 704 is fixedly mounted on the output end of the reducer 703.

[0033] In this embodiment, as Figure 1 As shown, the flip cover assembly 17 includes a pivot seat 1701, a rotating block is rotatably connected to the shaft surface of the pivot seat 1701, a top plate 1702 is fixedly connected to one side of the rotating block, a handle is fixedly installed on the top of the top plate 1702, an mounting block is fixedly installed on one side of the top plate 1702, a spring 1703 is fixedly installed on one side of the mounting block, an insertion rod 1704 is fixedly installed on one side of the spring 1703, and a pull rod is fixedly installed on the surface of the insertion rod 1704.

[0034] In this embodiment, as Figure 1 As shown, the screen box 1 is inclined, and the support base 2 has one set higher and one set lower.

[0035] In this embodiment, as Figure 3 As shown, one end of the main shaft 6 is fixedly mounted on the rotation center of the eccentric wheel 704.

[0036] In this embodiment, as Figure 3As shown, a frame is fixedly installed around the screen 9, and sliding blocks are fixedly installed on the left and right sides of the frame. A groove is provided at one end of the frame.

[0037] In this embodiment, as Figure 2 As shown, a fixing block is fixedly installed on the surface of the cover plate 16, and a circular groove is opened at the position corresponding to the insertion rod 1704 on the fixing block.

[0038] The working process of this sieving machine with easy screen removal is as follows:

[0039] First, pull the handle on the surface of the top plate 1702. The top plate 1702 rotates around the shaft seat 1701 and opens. Non-metallic minerals to be screened are fed into the screen box 1 through the opened feed inlet. After feeding, the top plate 1702 is closed. Then, pull the lever on the surface of the insertion rod 1704, compressing the spring 1703. At this time, one end of the insertion rod 1704 aligns with the circular groove of the fixing block. Release the lever, and the spring 1703 rebounds, pushing the insertion rod 1704 into the circular groove. The spring locking force securely locks the top plate 1702 onto the cover plate 16. Start the asynchronous motor 701, which converts electrical energy into high-speed rotational motion and transmits it to the reducer 703 through the coupling 702. The speed reducer 703 converts the input high speed and low torque into low speed and high torque output, driving the eccentric wheel 704 to rotate. The eccentric wheel 704 uses its eccentricity to directly convert the low-speed rotational motion output by the speed reducer 703 into vibration. This vibration is transmitted to the screen box 1 through the main shaft 6. When the screen box 1 vibrates, the rotating shaft 5 drives the movable plate 4 to vibrate together with the support base 2 supported by the buffer spring 3. The input non-metallic minerals vibrate continuously on the inclined screen 9 and flow forward. Small mineral particles fall into the bottom of the screen box 1 through the screen 9 and are finally discharged through the lower discharge pipe 12. Larger mineral particles remain on the surface of the screen 9 and are discharged through the upper discharge pipe 11.

[0040] When the screen 9 needs to be replaced, rotate the buckle 14 to disengage it from the slot 15, pull down the handle on the surface of the side plate 13, and the side plate 13 will rotate around the hinge to open. At this time, pull the groove at one end of the screen 9, and the screen 9 will slide along the slide rail 8 through the slider on it, separating from the bottom plate 10. The screen 9 can then be taken out for cleaning or replacement.
