Abstract
One kind tests the speed formula rotary feeder, including the gear shaft being arranged on gear bracing strut, measure speed gears, grating encoder one end and gear axis connection is provided on gear shaft, the other end is connect with display instrument.It is distorted small it is an advantage of the invention that testing the speed, material instantaneous velocity can be measured immediately.
Description
Technical field
Belong to Weighing type conveyer the present invention relates to one kind, in particular to one kind tests the speed formula rotary feeder.
Background technique
The speed measuring device that helical feed metering weighing system is widely used at present generallys use acquisition driving motor revolving speed and makees
It is measuring parameter to determine material movement speed.Due to promotion of the movement mainly by blade of material in screw(-type) feeder, material
Itself not only to overcome the frictional force of cylinder, while can also generate radial movement or generation because of the friction with blade radial
Radial movement tendency.Material includes water content in addition, and the property of itself is not constant uniform, therefore in spiral machine drum body
Interior material is actually to do very complicated variable motion, and what weighing measurement required acquisition is material output cylinder instantaneous time
Axial velocity, therefore the moment when revolving speed for acquiring driving motor cannot show material output as measuring parameter is axial fast
Degree, this makes metering generate very big error, symmetrically remakes into very big influence, to solve this problem, need to cartridge outlet
Material be axially moved instantaneous velocity have real-time measurement.
Summary of the invention
The object of the present invention is to provide the formula rotary feeders that tests the speed that one kind can measure material conveying instantaneous velocity.
In order to achieve the above object, the technical scheme is that including the gear shaft being arranged on gear bracing strut, in tooth
Measure speed gears, grating encoder one end and gear axis connection are provided on wheel shaft, the other end is connect with display instrument.
The present invention is by being welded to connect in the tail portion cylinder lower end of material screw conveyer, and speed transmission part is using biography
The minimum gear mechanism transmission device of dynamic distortion, the tachometric survey part grating encoder high using sensitivity, measure speed gears
Feeding cylinder is protruded into upper part, and measure speed gears are moved under the drive of material during exercise, grating encoder with test the speed
Gear axis connection is moved with measure speed gears axis, and the electric signal of generation is tachometer signal, can accurately feed back screw machine outlet object
Expect the instantaneous axial velocity of conveying.It is distorted small it is an advantage of the invention that testing the speed, material instantaneous velocity can be measured immediately.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
As shown in Figure 1, the present invention includes the gear shaft 3 being arranged on gear bracing strut 4, survey is provided on gear shaft 3
Fast gear 5,1 one end of grating encoder are connect with gear shaft 3, and the other end is connect with display instrument 2.
When work, gear bracing strut 4 of the invention is fixed below the tail portion cylinder of weighing type spiral batcher, is tested the speed
Feeding cylinder is protruded into the upper part of gear 5, and the material filled in cylinder when testing the speed drives barrel front end lower part measure speed gears 5 to transport
Dynamic, the measure speed gears 5 in movement drive grating encoder 1 to generate pulse signal as metering signal.
Claims (1)
- The formula rotary feeder 1. one kind tests the speed, it is characterised in that: including gear shaft (3) on gear bracing strut (4) is arranged, It is provided on gear shaft (3) measure speed gears (5), grating encoder (1) one end is connect with gear shaft (3), the other end and display instrument Table (2) connection.
