The elastic elements of the device do not bear the weight of the charging tray and material any longer; therefore, the service life of the elastic elements is extended, delivery efficiency is enhanced, and energy consumption is reduced.
Description
Technical field
The present invention relates to oscillation feed gear, particularly a kind of oscillation feed gear of Piezoelectric Driving.
Background technology
Along with developing rapidly of product semi-automation, automated production, just seem very important as the development of improving product S. A., automatic conveying equipment.
Traditional oscillation feed gear structurally generally can be divided into two kinds, and a kind of is the dead-beat pay-off, and another kind is spiral pay-off.Most spiral oscillation feed gears are Electromagnetic Drive, the spiral oscillation feed gear that Piezoelectric Driving also occurred at present, its structure comprises charging tray 1, is pasted with the elastic element 4 of piezoelectric ceramic piece 3 and connects oscillatory system, the base 11 that the source of AC of piezoelectric ceramic piece 3 forms and form as shown in Figure 2.The upper end of elastic element 4 is fixed on the charging tray 1, and its lower end is fixed on the base 11, and elastic element 4 usefulness elasticity good metal materials are made.Elastic element 4 has two kinds of functions, and one is to cooperate with piezoelectric ceramic piece 3, under the excitation of alternating current, makes charging tray 1 produce little amplitude and comes and goes torsional oscillation; Its two, be that charging tray 1 is played a supportive role.
When on piezoelectric ceramic piece 3, adding alternating current, piezoelectric ceramic piece 3 produces deformation, drive the elastic element 4 that tilts to install and produce vibration clocklike, material is under the combined action of force of inertia, gravity and friction force, plug helix upward movement along charging tray 1 inwall, discharging opening by charging tray 1 top enters feeding groove then, is sent to Working position.
That the spiral oscillation feed gear of this Piezoelectric Driving has is simple in structure, noise is low, long-lived advantage, but there is following shortcoming in it:
1, the excitation that both had been used in alternating current of the oscillatory system formed of elastic element and piezoelectric ceramic piece produces vibration down, is used for supporting charging tray again, so the gravity long term of material and charging tray is on elastic element.Can cause the either large or small distortion of elastic element, further influence the vibration performance of piezoelectric ceramic piece attached thereto, and the stressed complexity of elastic element, this Several Factors is bigger to the stability of vibration influence of this device.In addition, the long-term stressed fracture by fatigue that also easily causes producing of elastic element.
2, the oscillatory system of this device upper end is fixed on the charging tray, and the lower end is fixed on the base, and this fixing mode can produce constraint to the torsional oscillation of charging tray, the motion of restriction charging tray.
3, the vibration of piezoelectric ceramic piece not only will overcome the fixed constraint of oscillatory system, also will overcome the suffered application force of oscillatory system itself, so the expenditure of energy of piezoelectric ceramic piece is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of floating type piezoelectric vibration spiral feeder that improves structure, to overcome the above-mentioned shortcoming that present this device exists.
The floating type piezoelectric vibration spiral feeder of the present invention, comprise the inboard have the charging tray of spiral slide, by the elastic element that is pasted with piezoelectric ceramic piece with connect oscillatory system, the base that the source of AC of piezoelectric ceramic piece is formed, it is characterized in that: the lower end of described charging tray is by the triangular pillar circular base slab that is connected, three described elastic elements that are pasted with piezoelectric ceramic piece are on three sides that are arranged on the triangular pillar of leaf wing formula by little stay bearing plate respectively, and angled with vertical surface; Set firmly a chassis with U-lag on described base, place ball in its U-lag, circular base slab is sat and is put on ball, is installed in two stop screws on the chassis and is inserted in respectively in two spacing holes on the circular base slab.
The present invention has the following advantages:
1, this device has adopted the charging tray that has triangular pillar and circular base slab, this structure makes elastic element no longer bear the weight of charging tray and material, only be used to cooperate piezoelectric patches to produce vibration, thereby eliminated of the influence of the weight of charging tray and material, increased the life-span of elastic element piezoelectric ceramic piece and elastic element vibration.
2, this device has adopted the structure of floating type charging tray, eliminated because of the constraint that fixedly bring of elastic element on charging tray and base, the body vibration of charging tray is more abundant, thereby improved transport efficiency (being several times even tens times of spiral oscillation feed gear of present Piezoelectric Driving), and reduced the consumption (being below 1/2 of present prezoelectric vibration hopper) of energy.
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 variable-rate fertilization.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing further describes structure of the present invention.
Fig. 1 is the structural representation of the floating type piezoelectric vibration spiral feeder of the present invention;
Fig. 2 is the structural representation of the pay-off that shakes of present spiral Piezoelectric Driving.
The specific embodiment
With reference to Fig. 1, the floating type piezoelectric vibration spiral feeder of the present invention, comprise the inboard have the charging tray 1 of spiral slide, by the elastic element 4 that is pasted with piezoelectric ceramic piece 3 with connect oscillatory system, the base 9 that the source of AC of piezoelectric ceramic piece 3 is formed, the lower end of described charging tray 1 is by triangular pillar 2 circular base slab 6 that is connected, three described elastic elements 4 that are pasted with piezoelectric ceramic piece 3 are on three sides that are arranged on triangular pillar 2 of leaf wing formula by ramuscule fagging 5 respectively, and angled with vertical surface; Set firmly a chassis 8 with U-lag on described base 9, place ball 7 in its U-lag, circular base slab 6 is sat and is put on ball 7, is installed in two stop screws 10 on the chassis 8 and is inserted in respectively in two spacing holes on the circular base slab 6.
Tolerance clearance between described stop screw 10 and the circular base slab 6 upper limit holes is 1-3mm.Like this, can guarantee that charging tray 1 torsional oscillation in the horizontal direction is unrestricted, guarantee charging tray 1 whole one-tenth quick condition in vertical direction simultaneously, be convenient to vibration.
