The technical problem to be solved by the technology is: in order to overcome the lack of inconvenient recovery of residual materials on the bucket elevator in the prior art, the technology provides a vertical elevator. The technical plan to be adopted by this technology to deal with its technical problems is: a vibration vertical hoist, including a base and a central column, casing and disc arranged on the base. The central column is vertically arranged at the upper end of the base, the casing is sleeved on the central column, and a plurality of springs are obliquely arranged between the upper end of the casing and the side wall of the central column, The casing is provided with a morning moving mechanism for driving the casing to vibrate along the axial direction, the disc is spirally arranged on the outer wall of the casing, the side of the disc close to the base is provided with a drainage hole, the drainage hole is sealed with a sealing plate, and the sealing plate is connected with the disc. In the same factory, the temperature of another transported material is 120. The results indicate the opposite pressure distribution environment, that is, the lower part of the ring chain bucket elevator is the male turn water column and the upper part is the male box water column. Many experiments have been done on the ring chain bucket elevator, and similar signs have been obtained.



Ring chain bucket elevators are cheap. Therefore, in most cases, they are used in the open air. For elevators operating in the open air, the crane is located at the head (top). Add a square cover, because the motor and reducer at the head are the power source of the whole equipment. If there is no top cover, the motor may enter the water under the influence of bad weather such as rain or snow. A condition that causes a short circuit. Therefore, the bucket elevator working in the open environment must be equipped with a top cover on the top to completely cover the head of the equipment, so as to ensure that the lifting equipment is not affected by the environment in the open environment. According to the roof escort of the traction machine manufacturer, the bucket elevator is densely arranged and runs fast. The materials move through the chute from the tail inlet to the bottom, which is easy to accumulate. When the tail wheel rotates to dig data, the bucket rotates upward at the bottom. During the excavation, the grain pile at the bottom was squeezed by the barrel, resulting in crushing and crushing. When the bucket is full of material and continues to rotate, the material outside the bucket will rub with the bucket and tail deflector, resulting in friction and cracking. When the bucket moves to the upper part, the material collides with the thread part of the bucket and the bucket bolt head. At the moment of impact, the corn kernels collide with the high-strength barrel and are cut with the sharp corners of the threads to form cracks.

The structure of trimming pin shaft and trimming sleeve is adopted. The assembly of pin shaft and outer chain plate, sleeve and inner chain plate adopts tight fit (interference) with large interference, which solves the problem of relative rotation between pin shaft and outer chain plate Optimize material selection and heat treatment process to improve the wear and fatigue resistance of hoist chain. Sleeve; Material: 40Cr, quenched hrc50~54; Pin shaft: Material: 20CrMnMo, carburizing and quenching hrc58~ layer depth; Roller: 40Cr, quenched hrc48~52; Inner and outer chain plate: material 65Mn, punching and normalizing (hb280~3) and hole squeezing process. Problem analysis: the plate chain bucket elevator is an open-air operation, and the amount of rain in the previous period is large. Although the pit is covered with plates during the rainy time, the rain still flows into the pit and infiltrates into the base to damp the slag ash. Treatment plan: it is recommended that users coil the pit of the bucket elevator to build a rain shelter to reduce the inflow of rain. Another problem is The arc-shaped plate welded at the bottom in the treatment plan also separates the materials from the pit air, which largely eliminates the infiltration of moisture in the air at the bottom, and well solves the problem of moisture in the powder of the bucket elevator base. This technology touches the technical scope of the elevator, especially a vibrating vertical elevator. After the materials are extruded and water-cooled and granulated, they need to be treated by far classification through the vibrating screen The storage is stopped in the incoming storage bin, but the height of the discharge port of the vibrating screen from the air is very low. It is required to use the hoist to lift the materials to a certain height and put them into the storage bin. After the hoist is used, a large amount of materials remain on the lifting disc, which is not easy to recover, resulting in resource waste.



The design of bucket elevator hopper is mainly to confirm the type, volume and main geometric dimensions (width extension a and height h), and check carefully: how to calculate the discharge parameters of bucket elevator hopper. The shallow bucket is characterized by the deep inclination between the front edge of the bucket elevator hopper and the vertical section of the bucket back, the bucket is large (at an angle of 45) and the depth is small. The hopper of this bucket elevator is mainly used to discharge wet and inactive granular materials, such as wet sand and wet raw coal. From the structural characteristics of this bucket, it can be seen that due to its small depth and large inclination of the front edge, the hopper can be relatively easy to empty during unloading. Both deep bucket and shallow bucket have curved bottom, which will not make the materials stick to the bucket bottom, so it is conducive to good unloading. Z-type feeding, C-type feeding, z-c mixed feeding, multi-point feeding, multi-point blanking and other places. At present, it is mainly used for the feeding of weighing and packaging machines, the feeding and check feeding of color separators, and the plane cycle loading and unloading of automatic consumption lines. At present, our products normally operate in the following automatic consumption industries: pet food industry, expanded food industry, feed industry, candy industry, dry and fresh fruit industry, health food industry, grain processing department, real estate, chemical industry, hardware and electrical materials industry, manufacturing industry, etc. Continuous vertical hoist

The working principle of the bucket elevator is as follows: the hopper scoops up the materials from the storage below. With the lifting of the escort belt or chain to the top, it turns down after bypassing the top wheel, and the bucket elevator dumps the materials into the bearing groove. The drive belt of bucket elevator with belt drive generally adopts rubber belt, which is installed on the lower or upper drive drum and the upper and lower change direction drum. Chain driven bucket elevator is generally equipped with two parallel transmission chains, with a pair of transmission sprockets on or below, and a pair of reversing sprockets on or above. Bucket elevators are generally equipped with casings to avoid dust flying in bucket elevators. Generally speaking, the form of materials directly determines the unloading mode of materials. The common law is that powdery materials are unloaded by centrifugal ejection and massive materials are unloaded by gravity. Different unloading modes determine the hopper mode of bucket elevators, Shallow bucket and arc bucket are mostly used for centrifugal ejection unloading, while deep bucket is required for gravity unloading.

The base is used to support the central column, the casing is sleeved on the central column for the casing to slide up and down along the central column, the vibration mechanism is matched with the spring to move the casing up and down on the central column, the disc is used to lift the materials on the disc up through vibration to stop material transportation, and the drainage hole is used to wash the disc with water, Connect the drain hole with the recovery installation through the water pipe to stop the recovery of the materials remaining on the disc. The sealing plate is used for the elevator to avoid the leakage of materials from the drain hole when transporting materials. Further, a buffer pad is arranged between the sleeve and the base in order to avoid abrasion caused by collision between the sleeve and the base when the sleeve vibrates on the center column. Bucket elevator escort machine is a part of logistics escort system. Referring to the foreign bucket elevator technology, this series of elevator has the advantages of small power distribution, slow linear speed, large lifting capacity, compact structure and simple operation. It is a new non crushing elevator manufactured in China. Muxiang bucket elevator takes the flat tape as the transmission medium to drive the lifting bucket to operate in a circular manner, so as to transport rice to the location.
