Description

Technical Field

[0001] The utility model relates to the technical field of rotary vibrating screens, in particular to a rotary vibrating screen charging and unloading device. Background Art

[0002] A rotary vibrating screen (also known as a circular vibrating screen or circular vibrating screen) is a common screening equipment. It mainly uses a motor to drive an exciter to generate rotary vibration, causing the material on the screen surface to move in three dimensions, thereby achieving the purpose of material grading and screening. This type of screening machine is widely used in many industries due to its high efficiency and stable working performance, such as mining, food processing, pharmaceuticals, chemical industry and other fields. The feeding and unloading device is one of the important components of the rotary vibrating screen and plays an important role in ensuring screening efficiency.

[0003] In the patent application number 202022895813.5, an automatic feeding and unloading device for a crushing rotary vibrating screen is disclosed. In the disclosed feeding and unloading device, a feed hopper, a first conveying box and a first conveying mechanism are provided to realize the conveying of materials, so that it is convenient to add materials to the interior of the crushing rotary vibrating screen. It uses rotating spiral conveying blades to realize the conveying of materials. However, in actual use, when the material passes through the spiral conveying blades inside the conveying box, material will remain on the inner wall of the conveying box, making it difficult to convey the material entering the conveying box more thoroughly, and it is also inconvenient to clean the material attached to the inner wall. Based on this, a feeding and unloading device for a rotary vibrating screen is proposed herein. Utility Model Content

[0004] The purpose of the utility model is to provide a rotary vibrating screen charging and unloading device to solve the above-mentioned technical deficiencies.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a rotary vibrating screen feeding and unloading device, comprising a conveying cylinder, a motor mounted on one end of the outer wall of the conveying cylinder, an output end of the motor mounted on a connecting rod extending into the interior of the conveying cylinder, a conveying blade mounted on the outside of the connecting rod, and further comprising:

[0006] A first screw rod and a second screw rod, wherein the first screw rod and the second screw rod are symmetrically arranged at the upper and lower ends of the interior of the conveying cylinder, and the thread directions of the first screw rod and the second screw rod are opposite, and a scraper ring that fits the inner wall of the conveying cylinder is installed on the outside of the first screw rod and the second screw rod through a screw nut seat;

[0007] A gear drive structure, comprising a first gear, a second gear, and a third gear, wherein the second gear is mounted on the outside of the connecting rod, the first gear is detachably connected to the outer end of the second screw rod, and the third gear is detachably connected to the outer end of the first screw rod;

[0008] A moving assembly is used to enable the first gear and the third gear to engage with the second gear or to be disengaged from the second gear.

[0009] Preferably, the moving component includes:

[0010] The electric telescopic rod is installed on the upper end surface of the conveying cylinder;

[0011] The vertical bar is installed vertically at the output end of the electric telescopic rod;

[0012] A mounting rod, wherein the first gear and the vertical bar, and the third gear and the vertical bar are both hingedly connected to the mounting rod;

[0013] Two docking posts are respectively installed on the surface of the first gear and the third gear away from the mounting rod, and the ends of the docking posts are provided with hexagonal grooves. The outer ends of the first screw rod and the second screw rod are both fixed with hexagonal posts.

[0014] Preferably, the first gear, the second gear and the third gear are each provided with a protective cover on the outside, and the motor is mounted on the protective cover.

[0015] Preferably, one side of the top end of the conveying cylinder is connected to a feeding hopper, and the other side of the bottom end of the conveying cylinder is connected to a discharging hopper.

[0016] Preferably, the bottom end of the conveying cylinder is connected to a supporting leg, and the bottom end of the supporting leg is fixed with a bottom plate.

[0017] Preferably, an observation window is embedded in the outer wall of the conveying cylinder.

[0018] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0019] 1. By arranging the first screw rod, the second screw rod, the scraper ring and the gear drive structure, the scraper ring fits closely with the inner wall of the conveying barrel and moves. During its movement, it can effectively scrape off the materials attached to the inner wall of the conveying barrel. This cleaning method avoids the tedious and inefficient manual cleaning, and does not require workers to enter the conveying barrel for dangerous and laborious cleaning operations, which greatly improves the cleaning efficiency. At the same time, it also ensures the safety of personnel during the cleaning process, and can ensure that the inner wall of the conveying barrel is cleaned more thoroughly, which is conducive to maintaining the good working condition of the conveying barrel.

[0020] 2. The ingenious design of the moving assembly allows the first and third gears to flexibly engage or disengage with the second gear according to actual needs. When the equipment is in the normal loading and unloading phase, the moving assembly adjusts the first and third gears to a state of disengagement from the second gear. In this state, the scraper ring, without the driving force provided by the gear transmission, will remain stationary on one side of the conveyor barrel. This way, the scraper ring will not interfere with the normal loading and unloading process of the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] When unloading, first ensure that the first gear 11 and the third gear 13 are not engaged with the second gear 12, align the feeding hopper 2 with the discharge port of the rotary vibrating screen, and drive the connecting rod 9 equipped with the conveying blade 10 to rotate through the motor 7 to guide the material out.

[0043] Among them, when cleaning the material attached to the inner wall, the electric telescopic rod 171 can be retracted first, so that the mounting rod 173 drives the first gear 11 and the third gear 13 to engage with the second gear 12, and then the motor 7 drives the connecting rod 9 to rotate, which can drive the second gear 12 to rotate, and then drive the meshed first gear 11 and the third gear 13 to rotate, and then the first screw rod 14 and the second screw rod 15 with opposite threads can be rotated, and then the screw nut seat can be used to drive the scraper ring 16 to move, and the scraper ring 16 can be used to scrape the material on the inner wall for easy cleaning.
