Description
Technical Field
The invention relates to a high-efficiency vibration screening device for earth and stone discrete bodies, belonging to the technical field of geotechnical engineering, mineral engineering and agricultural engineering.
Background
Research objects in the fields of geotechnical engineering, mineral engineering, agricultural engineering and the like are usually discrete materials such as waste rocks, soil or tailings, and taking soil as an example, the grading of the soil has great influence on the engineering characteristics of the soil, so that the grading of the soil sample to be researched is obtained through a screening test and is usually the first work of research.
The screening operation is the most widely and effectively used method for grading materials according to particle size at present, is widely applied to the fields of mining industry, metallurgy, building materials, food, medicine, chemical industry, energy, environment and the like, and is a material preparation process for the purpose of product sale or for adjusting other processes. The result of the screening operation has an important influence on the efficiency of the next operation and also has a great influence on the value of commodities generated directly or indirectly.
The process of passing the loose mixed material through the screen openings of a single or multiple screen surfaces to separate it into two or several different size fractions according to their particle size is called screening. Screening operations have a long history in human production activities. Taking the coal processing industry as an example, relevant documents in the uk have been described about coal screening as early as 1589 years. In the second half of the 19 th century, due to market needs, screening and classification of coal has prevailed in order to provide commercial coals of various particle sizes. The appearance of vibrating screens in the 40's of the 20 th century marks the entry of modern screening technology into a new stage of development. With the continuous development of the coal processing industry, screening work is increasingly becoming an indispensable part of the coal processing industry. In the modern coal industry, the screening operation is not only used for creating conditions for other coal preparation methods, but also directly related to the economic benefits of the coal product supply and production departments. Through screening and grading, the quality of coal products can be improved, the varieties can be increased, and the method has important significance for reducing environmental pollution, improving the utilization efficiency of coal and improving social and economic benefits. It is considered that the screening work and the sorting work are equally important in terms of coal processing. Schreckentost even thinks that screening operation is the most important process link in coal preparation plants, and has profound influence on effective coal preparation, commercial coal recovery, product dehydration and drying, and the like, so to speak: sieving is the soul of coal dressing processing. Particularly, compared with the coal sorting operation, the screening operation also has the characteristics of simplicity, practicability, less investment, quick effect and convenient management.
Similar to the coal industry, screening operations are also widely used in other industrial sectors and are a significant priority. For example, in hydraulic engineering sites such as three gorges and small wave bottoms, various screening machines are used for screening sandstone materials; in addition, screening is widely used to purify materials in the fields of salt production, grain processing and the like.
Although screening is an old classification method, the screening operation is still the most widely and effectively applied method for classifying materials according to particle sizes so far, and the screening method can process various materials with particle sizes from 0.1 to 300mm and even larger. Although the application fields of the screening work are different and the objects to be treated are different, the screening mechanism is consistent. From an intuitive point of view, the screening operation is a simple separation process: through size comparison between the particles and the sieve pores, the particles smaller than the sieve pores pass through the sieve to become undersize, and the particles larger than the sieve pores are left on the sieve surface to become oversize, so that separation of coarse and fine particles is realized. However, in practical industrial applications, it is not easy to achieve a perfect separation of the material by particle size due to the requirement of a certain throughput. As an intricate separation process involving particle populations, american scholars r.e. galloway summarized 24 factors affecting screening as early as 1964. The advent of vibrating screens in the 30's of the 20 th century marked the development of modern screening technology. In order to reveal the relationship between the screening effect and the influence factors thereof, a great deal of research work is repeatedly carried out by related personnel, a plurality of new screening theories and novel screening machines are developed, and people continuously and deeply know the screening science. However, due to the complexity of the screening process and the incompleteness of instruments and equipment for detection and analysis, many relevant arguments are provided under specific preconditions, and the hypothesis to be verified is only that even a part of screening theory and screening mathematical model which are widely used at present are not free from experience and semi-experience modes, so that people still have imperfect knowledge about the screening process. The australian scholars Standish believes that the screening operations are far from accurate and efficient in view of the results of the numerous industrial screens of the current generation.
At present, a few devices capable of realizing efficient screening are available, particularly in the field and other field power-free environments, the purpose of screening can be achieved only by manually shaking the screen by people, great labor force is consumed, the screening effect is not ideal enough, and the current scientific research requirements cannot be met.

running-board 1 takes place the motion under the exogenic action that the people stepped on to go to exert, through I3 and II 4 metal poles with power conduction to gear I5 and make it take place to rotate to drive II 6 gears with I5 interlock also take place to rotate, because the gear ratio of I5 gear is big than gear II 6, the slew velocity of II 6 gears can be enlargied.
The rotating shaft 22 of the gear II 6 rotates synchronously with the gear II 6, the roller I14 rotates along with the gear II through the belt I19, and therefore the belt II 13 connected with the roller I14 starts to move upwards. The soil on belt II 13 will be transported by belt II 13 to above rectangular funnel 21 and then through rectangular funnel 21 into the earth screen group 24 below.
The rotation of the roller I14 drives the rotation of the rotating shaft 22 of the gear II 6 through the belt I19, and the rotating shaft 22 of the gear II 6 rotates synchronously with the gear II 6. The rotation of the left rotating shaft 22 can drive the gear III 7 on the inner side of the left side wall of the frame 23 to rotate, and simultaneously drive the gear IV 8 meshed with the gear III 7 to rotate, the gear III 7 is larger than the gear IV 8, so that the rotating speed of the gear IV 8 is further amplified, and the rotation of the gear IV 8 can enable the connecting rod I9 on the gear to move simultaneously, and the transmission rod I33 moves along with the gear. The sliding blocks 29 on the two sliding rods 28 penetrating through the transmission rod I33 are clamped in the sliding grooves 37 on the inner wall of the left side of the frame 23, so that the sliding rods and the transmission rod I33 move back and forth in a horizontal plane repeatedly, and the geotechnical sieve group 24 is driven to move back and forth repeatedly.
Similarly, because the metal rod i 3, the metal rod ii 4, the gear i 5, the bearing i 32, the gear ii 6 and the rotating shaft 22 are symmetrically arranged on the left side and the right side of the frame 23, the movement of the pedal 1 can cause the gear vi 11 on the inner side of the right side wall of the frame 23 to rotate, and the gear v 10 meshed with the gear vi to rotate, the number of teeth of the gear vi 11 is greater than that of the gear v 10, so that the rotating speed of the gear v 10 is amplified, then the gear v 10 rotates to drive the connecting rod ii 12 connected with the gear v 10, and the driving rod ii 34 and two sliding rods connected with the driving rod ii 34 generate left and right repeated movement in a horizontal plane, thereby driving the geotechnical sieve group 24 to generate front and back repeated movement.
The geotechnical sieve group 24 can do two-dimensional repeated movement in the horizontal plane under the repeated action of the front and back movement and the left and right movement of the transmission rod I33 and the transmission rod II 34, when the rotating speed of each gear reaches a certain speed, the horizontal plane vibration of the geotechnical sieve group 24 is formed, so that soil entering the geotechnical sieve group 24 from the feeding system can generate relative vibration in the geotechnical sieve 42, and the soil can be separated according to the grain size under the action of each layer of screen 43, and the soil with the grain size smaller than that of the lowest layer of geotechnical sieve screen can be collected to the collection basin 27 under the action of the circular funnel 26.
After the screening work is finished, the pedal 1 is stopped to be stepped, the dustproof curtain 49 is lifted, the geotechnical sieve group 24 is taken out from the frame 23, the nuts 45 on the positioning rods 25 are unscrewed, the soil on each layer of geotechnical sieve 42 is respectively taken out and installed, the positioning rods are re-inserted into the small holes 48 on each geotechnical sieve and fixed by the nuts, the four positioning rods 25 are respectively inserted into the intersection positions of the two vertical slideways 38, and the dustproof curtain 49 is put down and then the screening work is continued.
Under the condition that power is supplied in an indoor test and the like, the motor 16 is connected with the connecting piece 35 of the roller I14 through the transmission 17, the motor rotates to drive the roller I14 to rotate, the belt I19 drives the rotating shaft 22 to rotate, and meanwhile, the belt II 13 connected with the roller I14 starts to move upwards, and the geotechnical sieve group generates plane vibration after transmission.
