Novel large feeder based on double vibrators

Abstract

An electromagnetic vibrator is impossible to be enlarged without limitation due to product economy, so that in some occasions with special requirements, a large electromagnetic vibrator cannot realize large-scale application of accurate feeding by customers due to poor capability. Aiming at the defects in the prior art, the utility model designs a novel large feeding vibrating screen based on double vibrators, and two large feeders are integrated into a super-large electromagnetic vibrating feeder so as to meet the material conveying requirements in some special occasions. The vibration table mainly comprises a main vibration table body, a secondary vibration table body, a supporting base, a main vibration isolation device, an auxiliary vibration isolation device, two sets of vibrators, two sets of auxiliary vibrators and a buffer layer, and the two sets of vibrators drive the main vibration table body to vibrate and are the main vibrators and the auxiliary vibrators respectively. The two-stage vibrators adopt different frequencies and different amplitudes, and the main vibrator connected with the main vibration table is braked by high frequency and low amplitude and is responsible for promoting dispersion of a transportation medium; the auxiliary vibrator connected with the secondary vibration table is low in frequency and high in amplitude and is responsible for pushing the conveying medium to advance.

Description

Technical Field

[0001] The utility model belongs to the field of feeders, in particular to a large-scale feeder based on double vibrators. Background Art

[0002] Feeder is a kind of material conveying equipment widely used in the industrial field. Its basic principle is to use the exciting force generated by vibration to make the material subject to periodic vibration in the vibration table, so as to achieve continuous and uniform conveying of the material. It is generally composed of a vibrator, a vibration isolation device, a feed trough and other parts. The exciting force is generated by the vibrator to make the feed trough vibrate, and the material moves in the feed trough due to the vibration. Since the vibrating feeder has the advantages of high conveying accuracy, easy operation and simple structure, it has been widely used in chemical, metallurgical, mining and other industries. Background technology mainly involves the development of material conveying technology and the application of vibration principles. With the improvement of the level of industrial production automation, the requirements for material conveying equipment are getting higher and higher. Electromagnetic vibrators cannot be unlimitedly enlarged due to the economic efficiency of the product, resulting in some special demand occasions. Large electromagnetic vibrators cannot achieve large-scale applications of customers for precise feeding due to their insufficient capabilities. Utility Model Content

DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] like Figure 1 , 2 As shown, a new type of large feeder based on double vibrators mainly includes a main vibrating table 1, a secondary vibrating table 2, a support seat 3, a main vibration isolation device 4, a secondary vibration isolation device 5, a main vibrator 6, a secondary vibrator 7 and a buffer layer 8. There are two groups of vibrators driving the main vibrating table 1 to vibrate, namely, a main vibrator 6 and a secondary vibrator 7; a secondary vibrating table 2 and a buffer layer 8 are arranged between the secondary vibrator 7 and the main vibrating table 1. The structure of the main vibrating table 1 includes a conveying bucket and a support 101; the structure of the secondary vibrating table 2 includes a table body and a secondary support 201; the structure of the support seat 3 includes a support seat base, a main support rod 301 and a secondary support rod 302. The support 101 is connected to the main support rod 301 through the main vibration isolation device 4; the secondary support 201 is connected to the secondary support rod 302 through the secondary vibration isolation device 5. The main vibrator 6 is installed on the main vibrating table 1, and the secondary vibrator 7 is installed on the secondary vibrating table 2. The secondary vibrating table 2 is fixedly connected to the buffer layer 8. The buffer layer 8 is made of rubber.

[0015] Working principle: When the machine starts working, the conveyed material enters the main vibration table 1, the main vibrator 6 and the auxiliary vibrator 7 start working, and the two-stage vibrator generates exciting force, which makes the main vibration table 1 and the secondary vibration table 2 vibrate, and the material moves in the main vibration table 1 due to the vibration. The two-stage vibrator uses different frequencies and amplitudes. The main vibrator 6 connected to the main vibration table 1 uses high-frequency and low-amplitude braking to drive the transport medium to disperse; the auxiliary vibrator 7 connected to the secondary vibration table 2 uses low-frequency and high-amplitude to push the transport medium forward.
