Description

Technical Field

[0001] The utility model belongs to the technical field of material screening, and particularly relates to a weighing and comparison device before and after screening of a swing screen. Background Technique

[0002] A swing screen is a special high-efficiency screening machine designed to meet the needs of high-output and high-precision screening. It simulates the effective principle of manual screening movement, conforms to all fine and ultra-fine range of powder and particulate materials, and is applicable to the material screening in industries such as chemistry, food and spices, plastics, mining, medicine, wood and plywood, metallurgy, rubber, feed, chemical fertilizer, etc. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN208146375U discloses a swing screen with a function of weighing screened materials. The base device can increase the stability of the whole swing screen. The materials on the first screen wire frame can fall into the storage tank placed at the upper end of the first storage nested groove through the first discharge connecting hose at the lower end of the first discharge port. The materials on the second screen wire frame can fall into the storage tank placed at the upper end of the second storage nested groove through the second discharge connecting hose at the lower end of the second discharge port. The screened materials at the bottom of the swing screen body can fall into the storage tank placed at the upper end of the third storage nested groove through the third discharge connecting hose at the lower end of the third discharge port. The three electronic weighing devices at the bottom can respectively weigh the weights of the containers inside the three storage nested grooves and display them through a liquid crystal display screen. By setting a weighing structure, the swing screen can respectively weigh various screened materials or materials of different sizes, which is convenient for the staff to judge and further process the materials. However, in actual use, when the amount of materials to be screened is large, it is not convenient to quickly pour out the materials poured into the storage tank, especially when there are many types of materials, the discharging and transportation are more inconvenient;

[0004] 2. After the swing screen screens the materials, usually various materials or materials of different sizes need to be screened out according to requirements. To facilitate the comparison of the weights of various materials, the weighing device often needs to set multiple weighing structures to weigh different materials at the same time. When screening materials multiple times, sometimes the types to be screened are more than the preset weighing structures. Therefore, the staff needs to weigh in batches, which is time-consuming and laborious. Content of the Utility Model

[0018] 1. The utility model solves the problem that the swing screen can weigh a variety of materials or materials of different sizes screened out separately by setting a weighing structure through the arrangement of a movable base and a carrying hopper, which is convenient for staff to judge and further process the materials. However, in actual use, when the amount of material to be screened is large, the material poured into the storage trough is not convenient to pour out quickly, especially when there are many types of materials, the discharge and transportation are more inconvenient. After the screened materials are poured into multiple carrying hoppers and weighed, the equipment is moved to the position where the material needs to be discharged through the movable base, and the rotating motor is controlled to drive the carrying hopper to rotate, so that the material is discharged along the inclined carrying hopper under the action of gravity.
