Embodiment Construction

[0009] The present invention will be described in further detail below with reference to the accompanying drawings.

[0010] like figure 1 , figure 2 As shown, the self-excited screen cleaning device includes a connecting rod 1, a weight 2 and an elastic element 3. One end of the connecting rod 1 is provided with a weight 2, and the other end of the connecting rod 1 is connected to the screen body through a bracket 4. 5 and is connected to the screen 7 through the hitting arm 6, and the elastic element 3 is sleeved on the connecting rod 1. Wherein, the elastic element 3 is a shearing rubber spring. In this embodiment, the kinetic energy provided by the reciprocating vibration of the vibrating screen is used to form a resonance system with the vibrating screen body, which is matched with elastic elements, and vibrates at its own natural frequency. A superimposed movement of different frequencies and different amplitudes, so as to achieve the purpose of sieving and self-clea...

Abstract

The invention relates to the technical field of vibratory screening machinery, in particular to a self-excited screen mesh cleaning device which comprises a connecting rod, a heavy punch and an elastic element. The heavy punch is arranged at one end of the connecting rod, the other end of the connecting rod is connected with a screen through a support and connected with a screen mesh through a beating arm, and the elastic element is connected on the connecting rod in a sleeved manner. By the aid of the structure, the self-excited screen mesh cleaning device and the vibratory screen form a resonance system by the aid of kinetic energy provided by reciprocating vibration of the vibratory screen and matching of the elastic element, so that screening is realized, and screen holes are automatically cleaned. Compared with a traditional cleaning device, an additionally connected power supply is omitted, and the self-excited screen mesh cleaning device is convenient to use, high in reliability and fine in cleaning effect. In addition, the self-excited screen mesh cleaning device has the advantages that the cleaning device is reasonable in design and simple in structure, cost is reduced and the like, and the cleaning device is mainly used for screening fine materials and can be widely used for enterprises such as chemical industries and mines.

Description

technical field [0001] The invention relates to the technical field of vibration screening machinery, in particular to a self-excited screen cleaning device. Background technique [0002] In the process of sieving materials in existing vibrating screens, due to uneven feeding of materials and uneven humidity of materials, materials are easily piled up and blocked on the screen surface. Since the vibrating screen works under the action of a relatively stable vibration force and amplitude, it is difficult to recover by itself when there is material stacking or hole blocking, and it is often necessary to manually clean the holes after stopping the machine. Not only the cleaning efficiency is low, but the labor intensity of the workers is high. And it directly affects the normal screening operation of the vibrating screen. In the current technology, the cleaning device is driven by the vibration source to generate forced vibration to achieve the purpose of cleaning. However, i...
