Description

Jigging conveyer

Technical field

The present invention relates to a kind of conveyer, particularly a kind of jigging conveyer.

Background technology

A kind of main process equipment that uses in getting the raw materials ready of industry such as wood-based plate, paper pulp papermaking chipped workshop section is a drum chipper, jigging conveyer then is a kind of load transfer device in the drum chipper material loading delivery system, it has the effect that log in heaps is disperseed, make log can be evenly smooth enter chipping machine, carry irregular, not smooth load transfer device with the bridging, putty, the chipping machine charging that solve in the log material loading.Existing jigging conveyer generally comprises base, cell body, driving device, swing arm, spring, cell body opens wide, cell body is connected with base with spring by swing arm, driving device and cell body Joint, driving device drives the cell body motion by eccentric drive, driving device mainly contains two kinds at present: a kind of is to adopt eccentric type vibrator to finish eccentric drive, and another kind is to adopt eccentric block to finish eccentric drive.The defective that adopts the jigging conveyer of present eccentric drive structural shape mainly to exist is: amplitude is to change, eccentric throw can't be fixed, amplitude and disturbance force are non-constant in the course of the work to make jigging conveyer like this, and the delivery rate instability is subjected to the influence of material bigger.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of amplitude constant, delivery rate and direction stable jigging conveyer.

Realize that the above-mentioned purpose technical scheme is: a kind of jigging conveyer, comprise base, cell body, driving device, swing arm, spring, one end of cell body is a feed end, the other end is a discharge end, between driving device and the cell body for captiveing joint, cell body is by swing arm and spring and base flexible connection, driving device includes motor, small belt pulley, big belt pulley, belt, eccentric shaft, outer bearing carrier, inner pedestal, bearing, eccentric shaft and big belt pulley Joint, eccentric shaft is by bearing and outer bearing carrier and inner pedestal flexible connection.

Further, described swing arm includes stay bearing plate, copper sheathing, bearing pin, and swing arm is connected by bearing pin with cell body, and swing arm is connected with base with pin by hinge.

Further, be provided with lubricating cup in the oil hole of described stay bearing plate.

Further, described motor is arranged on feed end one side of cell body.

Further, described eccentric shaft is connected by key with big belt pulley.

Further, described spring is a coil spring.

Further, described swing arm is symmetrical set in the cell body bottom, is fixed with synchronizing bar in relative two swing arms of left and right sides.

Further, described swing arm and spring are provided with in pairs, and the angle between the every pair of line of centers is 90 °.

After adopting technique scheme, have a lot of benefits: amplitude constant, delivery rate and direction are stable.The present invention passes through the special eccentric shaft of driven by motor as propulsion source, produces two exciting component during motion, and a component makes the present invention produce vertical shake, amplitude constant, and push-pull effort is constant, and material is thrown; Another component makes the present invention produce horizontal vibration, and material is travelled forward, and delivery rate and direction are stable.Be not subjected to the influence of material.

The specific embodiment

The present invention is further detailed explanation below in conjunction with drawings and Examples.

To shown in Figure 6, a kind of jigging conveyer comprises base 1, cell body 2, driving device 3, swing arm 5, spring 7, also comprises hinge 4, pin 9 as Fig. 1.Cell body 2 is open types, and an end of cell body 2 is a feed end 12, and the other end is a discharge end 13.Driving device 3 includes motor 6, small belt pulley 29, big belt pulley 23, belt 28, eccentric shaft 16, outer bearing carrier 22, inner pedestal 17, inside cap 18, bearing 21, rectangle steel 19, motor 6 is arranged on feed end 12 1 sides of cell body 2, motor 6 is by being bolted on the base 1, motor 6 and small belt pulley 29 Joints, small belt pulley 29 is connected by belt 28 with big belt pulley 23, big belt pulley 23, small belt pulley 29, belt 28 is covered with belt housing 8, eccentric shaft 16 passes through key 24 Joints with big belt pulley 23, be contained in back-up ring 25 in eccentric shaft 16 and big belt pulley 23 bonded assembly ends, be lined with bullet pad 26 and be fixed with bolt 27 by back-up ring 25 medium positions, to prevent the radial runout between big belt pulley 23 and the eccentric shaft 16.Eccentric shaft 16 is by bearing 21 and two outer bearing carriers 22 and two inner pedestals 17 flexible connections, two bearings 21 are housed in two inner pedestals 17, with inner pedestal 17 end face corresponding sections inside cap 18 is housed, the sealing felt collar 20 that seals is housed in inner pedestal 17 and inside cap 18, on two inner pedestals 17, be connected with rectangle steel 19, rectangle steel 19 again with cell body 2 Joints, thereby driving device 3 and cell body 2 are fixed together by rectangle steel 19.Cell body 2 flexibly connects with base 1 by swing arm 5 and spring 7.Swing arm 5 is symmetrical set 7 pairs in cell body 2 bottoms, and promptly the left side is provided with 7, and the right side also is provided with 7 in symmetric position, is fixed with synchronizing bar 11 in relative two swing arms 5 of left and right sides, and it is 7 that radical is set, and this set is so that synchronous during the present invention's campaign.Swing arm 5 and spring 7 are provided with in pairs, and the angle between the every pair of line of centers is 90 °, and promptly spring 7 left sides are 7,7 on right side.Spring 7 is a coil spring, spring 7 all is connected with spring bearer plate 10 with the junction of cell body 2 and base 1, swing arm 5 includes stay bearing plate 30, copper sheathing 31, bearing pin 32, in two stomidiums of stay bearing plate 30 copper sheathing 31 is housed, bearing pin 32 is contained in the copper sheathing 31, among the oil hole 30-1 of stay bearing plate 30 lubricating cup 15 is housed.Owing to be with copper sheathing 31 on the bearing pin 32, lubricating cup 15 also is housed on 30 on the stay bearing plate, therefore can play protection and lubricating effect, reduce wear, thereby prolong the service life of swing arm 5, make the junction activity more flexible.The top of swing arm 5 is connected by bearing pin 32 with cell body 2, and locating piece 14 also is equipped with in bearing pin 32 ends.The bottom of swing arm 5 is connected with base 1 with pin 9 by hinge 4.
