Description
Technical field
It is specifically a kind of flexible support screening machine the present invention relates to a kind of screening machine.
Background technology
The main purpose of screening machine is that, for screening particulate material, its industry applicatory is quite extensive, for example：Chemical industry, ceramics, food, electronics industry etc., filtering screening is given using screening machine in advance by raw material, facilitates access for next procedure, therefore the application of screening machine is quite extensive.Although existing screening machine disclosure satisfy that the screening requirement of granular material to a certain extent, often there is a problem of that screening efficiency is low and vibrating noise is big.
The content of the invention
In view of this, it is an object of the invention to provide a kind of flexible support screening machine, it can not only meet the screening requirement of particulate material, and have the advantages that screening efficiency is high and noise is low.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of flexible support screening machine, including frame, it is horizontally mounted in the frame and is provided with sieves groove, and the frame is provided with two support beams for being respectively supported at the sieves groove two ends, and flexible support spring is provided between the support beam and the sieves groove；The vibrational excitation mechanism for driving the sieves groove vibration is additionally provided with the frame.
Further, the vibrational excitation mechanism includes the vibrator below the sieves groove, the vibrator includes that cover is transmitted in the vibration that eccentric shaft and rotatable engagement are sleeved on the eccentric shaft and are engaged with the sieves groove, and the vibrational excitation mechanism also includes the drive mechanism for driving the eccentric shaft rotation.
Further, the drive mechanism includes shock electric machine and the transition rotating shaft being connected with the shock electric machine, and flexible linking device is provided between the transition rotating shaft and the eccentric shaft.
Further, the flexible linking device includes the flexible link belt being arranged between the transition rotating shaft and the eccentric shaft, and the two ends of the flexible link belt are fixedly connected respectively at the transition rotating shaft with eccentric shaft.
Further, the frame is provided with positioned at sieves groove top and for the position-limit mechanism of the spacing sieves groove extensional vibration displacement.
The beneficial effects of the present invention are：
Flexible support screening machine of the invention, it is arranged in support beam using flexible support spring by by sieves groove, so, sieves groove is driven to vibrate using vibrational excitation mechanism, the high-frequency reciprocating vibration of sieves groove can be realized in the presence of flexible support spring, and then realizes the screening purpose to material, have the advantages that screening efficiency is high, and flexible support spring can avoid rigid collision between sieves groove and frame, i.e., can reduce noise.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and illustrates：
Fig. 1 is the structural representation of flexible support screening machine embodiment of the present invention.
Fig. 2 is the right view of Fig. 1.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in figure 1, being the structural representation of flexible support screening machine embodiment of the present invention.The flexible support screening machine of the present embodiment, including frame 1, it is horizontally mounted in frame 1 and is provided with sieves groove 2, and frame 1 is provided with two support beams 3 for being respectively supported at the two ends of sieves groove 2, and flexible support spring 4 is provided between support beam 3 and sieves groove 2.The vibrational excitation mechanism for driving sieves groove 2 to vibrate is additionally provided with frame 1.The vibrational excitation mechanism of the present embodiment includes the vibrator 5 installed in the lower section of sieves groove 2, vibrator 5 includes the vibration transmission cover 7 that eccentric shaft 6 and rotatable engagement are sleeved on eccentric shaft 6 and are engaged with sieves groove 2, and vibrational excitation mechanism also includes the drive mechanism for driving eccentric shaft 6 to rotate.
Drive mechanism can realize that the drive mechanism of the present embodiment includes shock electric machine 8 and the transition rotating shaft 9 being connected with shock electric machine 8, and flexible linking device is provided between transition rotating shaft 9 and eccentric shaft 6 using various ways.The flexible linking device of the present embodiment includes the flexible link belt 10 being arranged between transition rotating shaft 9 and eccentric shaft 6, and the two ends of flexible link belt 10 are fixedly connected respectively at transition rotating shaft 9 with eccentric shaft 6.Transition rotating shaft 9 and eccentric shaft 6 are connected by using flexible link belt 10, can be filtered out because the rotation of eccentric shaft 6 produces vibration to be transferred on transition week 9, that is, ensure that the operation stability of drive mechanism.
Further, frame 1 is provided with positioned at the top of sieves groove 2 and for the position-limit mechanism 11 of the extensional vibration displacement of spacing sieves groove 2.Position-limit mechanism 11 realizes that the spacing between two pieces of swash plates is gradually reduced along vertically downward direction, and forms material charging spout 12 using two pieces of symmetrically arranged swash plates.
The flexible support screening machine of the present embodiment, it is arranged in support beam using flexible support spring by by sieves groove, so, sieves groove is driven to vibrate using vibrational excitation mechanism, the high-frequency reciprocating vibration of sieves groove can be realized in the presence of flexible support spring, and then realizes the screening purpose to material, have the advantages that screening efficiency is high, and flexible support spring can avoid rigid collision between sieves groove and frame, i.e., can reduce noise.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the present invention, protection scope of the present invention not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, within protection scope of the present invention.Protection scope of the present invention is defined by claims.
