Description

Technical Field

[0001] This utility model relates to the field of ore processing, and in particular to a screening device for quartz ore processing. Background Technology

[0002] A search of Chinese patents revealed publication number CN218797154U, which discloses a screening device for ore processing. The device includes a screening machine body with symmetrical mounting seats on its outer wall. Each mounting seat has a groove at its lower end and a through hole at its center. A first fixing plate is engaged within the groove at the lower end of the mounting seat. A support spring is fixed to the lower end of the first fixing plate, and a second fixing plate is mounted to the lower end of the support spring. A fixing block is fixed to the lower end of the second fixing plate, and a support frame is sleeved around the fixing block. A fixing base is mounted to the lower end of the support frame. A threaded post is fixed to the upper end of the first fixing plate, passing through the central through hole of the mounting seat. A fixing nut is sleeved around the threaded post. This ore processing screening device features a spring engagement structure, allowing for quick disassembly and installation of the spring, thus improving the efficiency of later equipment maintenance.

[0003] Existing screening devices cannot adjust the screen angle. Generally, the screen is fixed to the device, resulting in a fixed screen angle and screening speed, making it difficult to adjust as needed. This reduces practicality and applicability, and also makes screen replacement inconvenient. The screen is usually fixed to the device with multiple bolts, requiring tools for disassembly and reassembly for replacement, which is cumbersome, increases workload, and reduces replacement efficiency. To solve the above problems, we propose a screening device for quartz ore processing. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for quartz ore processing, which has the advantages of being able to adjust the angle of the screen and making it easy to replace the screen.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a screening device for quartz ore processing, comprising a base plate, a bottom frame hinged to the top of the base plate, a support rod bolted to the top of the base plate, a first sliding groove formed on the surface of the support rod, a first slider slidably connected to the inner wall of the first sliding groove, a crossbar bolted between the first sliders, a screw threadedly connected to the inner wall of the first slider, and the screw rotatably sleeved with the inner wall of the support rod, a first bevel gear fixedly sleeved at the bottom of the screw, a second bevel gear meshing with the surface of the first bevel gear, a drive shaft fixedly sleeved at the axis of the second bevel gear, and the drive shaft rotatably sleeved with the inner wall of the support rod, an adjusting motor bolted to one end of the drive shaft, and the adjusting motor bolted to the surface of the support rod.

[0006] By adopting the above technical solution, the rotation of the motor drives the transmission shaft to rotate the second bevel gear, which in turn drives the first bevel gear to rotate the screw, and the rotation of the screw causes the first slider to move the crossbar, thereby changing the angle of the screen. This achieves the purpose of adjusting the screen angle, improving practicality and applicability, and making it convenient to use.

[0007] The present invention is further configured as follows: a first spring is bolted to the top of the bottom frame, a fixed frame is bolted to the top of the first spring, a screen is slidably connected to the inner wall of the fixed frame, a cover plate is provided between the inner walls of the fixed frame, a snap-fit ​​rod is slidably sleeved on the inner wall of the cover plate, a snap-fit ​​hole is provided on the inner wall of the fixed frame and snaps with the snap-fit ​​rod, a second spring is provided between one end of the snap-fit ​​rod and the inner wall of the cover plate, a handle is bolted to the surface of the cover plate, a pull plate is slidably connected to the inner wall of the handle, pull rods are hinged to both ends of the pull plate, and the other end of the pull rod is hinged to the surface of the snap-fit ​​rod.

[0008] By adopting the above technical solution, the pull rod is moved by moving the pull plate, which causes the pull rod to move. The movement of the pull rod causes the pull rod to disengage from the pull hole, opening the cover plate and pulling the screen out of the fixed frame for replacement. This method can facilitate the replacement of the screen, reduce the workload, and improve the efficiency of replacement.

[0009] The present invention is further configured such that: a second sliding groove is provided at the bottom of the bottom frame, a second slider is slidably connected to the inner wall of the second sliding groove, and the second slider is hinged to the top of the crossbar.

[0012] By adopting the above technical solution, the ore is prevented from scattering by setting up a spill prevention frame.

[0013] The present invention is further configured such that one end of the snap-fit ​​rod is wedge-shaped.

[0014] By adopting the above technical solution, one end of the locking rod is wedge-shaped, which facilitates the fixing of the cover plate and makes it convenient to use.

[0015] The present invention is further configured such that a vibration motor is bolted to the surface of the fixed frame.

[0016] By adopting the above technical solution and setting up a vibrating motor, the efficiency and quality of screening can be improved.

[0020] By adopting the above technical solution, the motor is protected by setting up a protective shell.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the purpose of adjusting the screen angle by adjusting the rotation of the motor to drive the transmission shaft to rotate the second bevel gear, which in turn drives the first bevel gear to rotate the screw, and the screw to move the first slider and the crossbar. This improves the practicality and applicability of the screen and makes it easier to use.

[0023] 2. This utility model uses a movable pull plate to move the pull rod, which in turn moves the locking rod. The movement of the locking rod causes it to disengage from the locking hole, opening the cover plate and allowing the screen to be pulled out of the fixed frame for replacement. This method facilitates screen replacement, reduces workload, and improves replacement efficiency. Attached Figure Description
