Description
Technical field
The utility model relates to a kind of vibrating sieving machine, relates in particular to a kind of vibrating sieving machine with high vibration frequency.
Background technology
For a long time, be used for the standard screen vibrating sieving machine that the laboratory sizing is analyzed, formed by support, slew gear, rapping mechanism and clamp mechanism and bushing screen.There is complex structure in this machine, weight is big, cost is high, big, the clamp mechanism (comprising that rotation tightens bolt, sieve cover fixed mandril, sieve lid etc.) of vibration noise is difficult for sieving shortcomings such as covering axially moving up and down of guide rod upper edge guide rod when inconvenient maintenance, use.The vibrating sieving machine of being sold by certain factory's test manufacture adopts 3 cylindrical spring supportings of general employing standard hoops to tighten up framework in recent years, connecting eccentric wheel and weight with motor rotates in the horizontal direction and shakes, lack the vibration effect of plummet direction, factor such as unreasonable in screen(ing) machine design has in addition caused the vibration frequency of vibrating sieving machine not high, complex structure, weight is big, cost is high, the big and inconvenient shortcoming of noise when using.
The utility model content
The purpose of this utility model just is to provide in order to address the above problem a kind of high efficiency, noise is little when using, the vibration frequency is high vibrating sieving machine.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of vibrating sieving machine with high vibration frequency, comprise support, dust cover, sieve lid and screen cloth, described screen cloth is provided with described sieve lid, also comprise electromagnet, three spring leafs, armature, housing screw, crosspiece, tighten up cushion block, tighten up bar and rubber washer, the bottom of the bottom of described electromagnet and three described spring leafs is connected with described support, each described spring leaf becomes 77 ° of inclination angles with the upper surface of described support, the top of described three spring leafs is connected with the bottom of described armature, described sieve covers and is provided with the described cushion block that tightens up, described housing screw be connected with the described cushion block that tightens up again after described crosspiece is threaded, the described upper end that tightens up bar is connected with described crosspiece, and the described lower end that tightens up bar is connected with described armature.
Particularly, described vibrating sieving machine also comprises four groups of damping springs and four supporting bases, and the top of every group of described damping spring is connected with the bottom of described support, and the bottom of every group of described damping spring connects with the top of corresponding supporting base.
The utility model is a kind of have the vibrating sieving machine of high vibration frequency high efficiency, vibration frequency height, can reach within a short period of time the screening terminal point, simple in structure, in light weight, cost is low, noise is little when using.
Description of drawings
Fig. 1 is a kind of structural representation with vibrating sieving machine of high vibration frequency of the utility model.
Among the figure: 1-housing screw, 2-crosspiece, 3-tighten up cushion block, 4-sieve lid, 5-screen cloth, 6-and tighten up bar, 7-dust cover, 8-rubber washer, 9-armature, 10-electromagnet, 11-spring leaf, 12-support, 13-damping spring, 14-supporting base.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of vibrating sieving machine with high vibration frequency of the utility model, comprise support 12, dust cover 7, sieve covers 4 and screen cloth 5, screen cloth 5 is provided with sieve and covers 4, also comprise electromagnet 10, three spring leafs 11, armature 9, housing screw 1, crosspiece 2, tighten up cushion block 3, tighten up bar 6 and rubber washer 8, the bottom of the bottom of electromagnet 10 and three spring leafs 11 is connected with support 12, each spring leaf 11 becomes 77 ° of inclination angles with the upper surface of support 12, the top of three spring leafs 11 is connected with the bottom of armature 9, sieve covers 4 and is provided with and tightens up cushion block 3, housing screw 1 with after crosspiece 2 is threaded again with tighten up cushion block 3 and be connected, the upper end that tightens up bar 6 is connected with crosspiece 2, and the lower end that tightens up bar 6 is connected with armature 9.
Particularly, vibrating sieving machine also comprises four groups of damping springs 13 and four supporting bases 14, and the top of every group of damping spring 13 is connected with the bottom of support 12, and the bottom of every group of damping spring 13 connects with the top of corresponding supporting base 14.
Use the operation principle of a kind of vibrating sieving machine with high vibration frequency of the utility model as follows:
Earlier screen cloth 5 is packaged during use, sample ore is put on upper strata screen cloth 5 centres, center position is put and is tightened up cushion block 3 on sieve covers 4, screw housing screw 1, because rubber washer 8 has elasticity, can avoid producing noise during screening, has simultaneously and is convenient to tighten up screen cloth 5.After this, can carry out step-less adjustment to size of current to electromagnet 10 power supplies, simultaneously the Oscillation Amplitude of adjustable knotter screen net 5 (in case of necessity, can adjust Oscillation Amplitude by the gap that changes electromagnet 10 upper surfaces and armature 9 bottom surfaces).After reaching the screening time, unscrew clamp-screw 3, take down tightening up cushion block 3, can take down cuff, the check screening terminal point.
