Abstract
A suspended piezoelectric vibration-type charging hopper unit for the vibration feeding system is composed of a charging hopper, a charging chute above said charging hopper, and a vibration device consisting of elastic part, piezoelectric ceramic and AC power supply. Its advantages are low consumption of energy, no fatigue failure of elastic part and low cost.
Description
Technical field:
The present invention relates to the vibrating bunker in a kind of oscillation feed gear, particularly relate to a kind of vibrating bunker of suspension type Piezoelectric Driving.
Background technology:
Along with developing rapidly of product semi-automation, automated production, just seem very important as the development of the part automatic conveying equipment that improves product semi-automation, automated production.
Traditional oscillation feed gear is generally electromagnetic vibration hopper, and the vibrating bunker of Piezoelectric Driving has prezoelectric vibration hopper at present.Its structure comprises hopper 4, oscillatory system, 3 above snubber blocks and base 8 as shown in Figure 3.Be provided with part material conveying road in the hopper 4.Oscillatory system by piezoelectric ceramic piece more than 2 groups more than 5,2 groups elastic element 6 and piezoceramic controller form.The upper end of elastic element 6 is by being bolted on the hopper 4, and its lower end is by being bolted on the base 8, and elastic element 6 usefulness metallic materials are made.Elastic element 6 has two kinds of functions, and one is to cooperate with piezoelectric ceramic piece 5, under the control of piezoceramic controller, makes hopper 4 produce vibration clocklike; Its two, be that hopper 4 is played a supportive role.Each group, promptly 2 piezoelectric ceramic pieces 5 are bonded on the same elastic element 6 corresponding two sides.
Prezoelectric vibration hopper with respect to traditional electromagnetic vibration hopper have simple in structure, noise is low, long-lived advantage, but there is following shortcoming in it:
1, because elastic element both had been used for supporting hopper, is used for again cooperating, under the control of piezoceramic controller, produces and vibrate with piezoceramic.Therefore the gravity long term of material and hopper is on elastic element, and its size is bigger to the influence of the stability of vibration of elastic element, and elastic element easily produces fracture by fatigue.
2, the lower end of two of this hopper elastic elements is by being bolted on the base, and this fixing mode can produce constraint to the vibration of hopper, the motion of restriction hopper on the direction that material advances.
3, the vibration of piezoelectric ceramic piece not only will overcome the fixed constraint of elastic element, also will overcome the suffered application force of elastic element itself, so the expenditure of energy of piezoelectric ceramic piece is bigger.
4, because the upper end of elastic element connects hopper, the lower end connects base, this device body vibration during hopper work, so though its noise is little than the noise of electromagnetic vibration hopper, still very big.
5, oscillatory system comprises 2 groups of above piezoelectric ceramic pieces, and every group has 4 piezoelectric ceramic pieces, because the quantity of applying piezoelectric sheet is more, has not only improved cost, and has made the oscillatory system structure more complicated.
Summary of the invention
The purpose of this invention is to provide a kind of suspension type piezoelectric vibro-hopper that improves structure, bigger with the expenditure of energy that overcomes the piezoelectric ceramic piece that present prezoelectric vibration hopper exists, elastic element easily produces above-mentioned shortcomings such as fracture by fatigue, cost height.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows.
A kind of suspension type piezoelectric vibro-hopper, comprise hopper 4, oscillatory system and hopper 1, said oscillatory system is made up of elastic element 6 and piezoelectric ceramic piece 5 fixed thereon and the source of AC that connects piezoelectric ceramic piece 5, hopper 4 is suspended on the hopper 1 by attaching parts 7, and make it free motion in vertical plane surface, the upper end of described elastic element 6 is fixed on the rear wall of hopper 4, and the lower end is unsettled, and angled with hopper 4 horizontal surfaces.
Said attaching parts 7 can be flexible connecting member or U-shaped connecting rods such as woven dacron.
The present invention has the following advantages:
1, elastic element has only an end to be connected with hopper, has only partial vibration in the device, so the noise of this device reduces greatly.
2, the upper end of elastic element is unsettled, and the lower end is fixed on the rear wall of hopper, and this structure has reduced the overall volume of this device greatly.
3, this device has adopted the suspension type hopper, this structure makes elastic element no longer bear the weight of hopper and material, only be used to cooperate piezoelectric patches to produce vibration, thereby eliminated of the influence of the weight of hopper and material, increased the life-span of elastic element the elastic element vibration.
4, the suspension type bin design of this device, eliminated the constraint that fixedly brings because of hopper, the body vibration of hopper is more abundant, thereby improved transport efficiency (be present prezoelectric vibration hopper several times even tens times), and reduced the consumption (being below 1/2 of present prezoelectric vibration hopper) of energy.
5, the suspension type bin design of this device has reduced the overall dimensions of prezoelectric vibration hopper greatly, and has further simplified the structure of device.
6, this device has adopted 1 above piezoelectric ceramic piece, has reduced the number of applications of piezoelectric ceramic piece, has reduced the cost of device.
The present invention is particularly suitable for carrying multiple particulate matter and powder materials such as corn, wheat, paddy, soil, electric mechanical gadget, as is used for the pay-offs such as fertilizer variable feeding of rice photoelectric colour sorter, variable-rate fertilization.
