Abstract
The invention discloses a kind of subtraction micro-balance, including frame and multigroup weighing mechanism, the weighing mechanism includes hopper, header, converge and struggle against, weighing sensor, hitch, motor, material guiding screw and control module, the frame is set to frame structure, the weighing sensor is fixedly mounted in frame, the hopper fixes hanging in weighing sensor bottom by hitch, the hopper bottom is connected with header sealing insertion, and the header discharging opening is communicated to remittance bucket, the motor is fixedly mounted in frame, described material guiding screw one end is connected to motor by shaft coupling, the other end sealing of the material guiding screw is placed in header.Due to hopper, hitch, motor and material guiding screw by hitch hanging in weighing sensor bottom, the sensitivity and weighing for realizing weighing are accurate, this micro-balance ensure that the accuracy of the material addition in each hopper by the way of the independent weighing of each hopper.
Description
Technical field：
Batching weighing equipment technical field of the present invention, is related to a kind of subtraction micro-balance.
Background technology：
, it is necessary to stir synthetic using a small amount of composition or several materials are matched somebody with somebody during feed and food is prepared
Material metering.For example, when preparing forage mixture or seasoning blend, it is necessary to be carried out to the accurate composition for determining proportioning strict
Errorless dispensing.Current micro proportioning scale selects the material dosing in addition scale, i.e. each barrel to be added in remittance bucket, then
It is unified to weigh the quality converged and struggled against, so, it only can guarantee that the gross mass after dispensing meets the requirements, and the material in each hopper
Addition is difficult to ensure that, and then influence prepares the quality of feed and food.
The content of the invention：
The technical problems to be solved by the invention are：Improve a kind of accurate subtraction micro-balance of weighing and burden.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of subtraction micro-balance, bag
Including rack and multigroup weighing mechanism, the weighing mechanism include hopper, header, remittance bucket, weighing sensor, hitch, driving
Motor, material guiding screw and control module, the frame are set to frame structure, and the weighing sensor is fixedly mounted on frame
On, the hopper fixes hanging in weighing sensor bottom by hitch, and the hopper bottom connects with header sealing insertion
Connect, and the header discharging opening is communicated to remittance bucket, and described material guiding screw one end is connected to motor by shaft coupling, described
The other end sealing rotation of material guiding screw is placed in header, and level sensor, the weighing and sensing are additionally provided with the hopper
Device and level sensor are connected to control module by circuit.
Preferably, setting hopper cover at the top of the hopper, safety lock is provided between the hopper cover and hopper.
Preferably, being further fixedly arranged on electromagnetic shaker on the headwall of the hopper.
Preferably, the frame be further fixedly arranged on the one-to-one gear wheel support of hopper, on the gear wheel support
Gear wheel is fixedly installed, the gear wheel is close on the outer wall of hopper.
Compared with prior art, usefulness of the present invention is：Due to hopper, hitch, motor and guide spiral shell
Bar is by hitch hanging in weighing sensor bottom, and the sensitivity and weighing for realizing weighing are accurate, and this subtraction is micro
Burden balance ensure that the accuracy of the material addition in each hopper by the way of the independent weighing of each hopper.
Brief description of the drawings：
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the axonometric drawing of the present invention.
Fig. 2 is the front view of the present invention.
Embodiment：
Below in conjunction with the accompanying drawings and embodiment the present invention will be described in detail：
A kind of subtraction micro-balance as depicted in figs. 1 and 2, including frame 1 and multigroup weighing mechanism, the weighing mechanism include material
Bucket 2, header 3,4, weighing sensor 5, hitch 6, motor 7, material guiding screw 8 and the control module, the frame 1 of struggling against of converging
Frame structure is set to, the weighing sensor 5 is fixedly mounted in frame 1, the hopper 2 is fixed by hitch 6 and hung
Hang over the bottom of weighing sensor 5, the hitch 6 may be configured as swing type structure, thus when the material increase in hopper 2 or
Person can be measured when reducing by weighing sensor, and the bottom of hopper 2 is connected with the sealing insertion of header 3, and the header 3 goes out
Material mouth is communicated to remittance bucket 4, and described one end of material guiding screw 8 is connected to motor 7 by shaft coupling, the material guiding screw 8 it is another
One end sealing rotation is placed in header 3, and level sensor is additionally provided with the hopper 2, and the weighing sensor 5 and material position are passed
Sensor is connected to control module by circuit, and the control module control motor 7 driving material guiding screw 8 rotates, described
Material guiding screw 8 drives the material in header 3 to be added to remittance bucket 4 during rotation, when weighing sensor 5 is measured in hopper 2
During the Mass lost of material to control module default value, control module is that the corresponding motor 7 of control stops operating, and then
It ensure that the accuracy of material addition in each hopper 2.
In actual use, in order that hopper 2 and extraneous region are completely isolated, the top of hopper 2 sets hopper cover 21,
Further for wrong throwing material is prevented, safety lock 22 is provided between the hopper cover 21 and hopper 2.
In addition, in order to avoid being further fixedly arranged on sizing caking phenomenon, the headwall of the hopper 2 occurs in the inwall of hopper 2
Electromagnetic shaker 23.
Because motor 7 can drive the lower end of hopper 2 to swing during startup, so hopper 2 is in length
Easily it is damaged during the use of phase, therefore, the frame 1 is further fixedly arranged on and the one-to-one gear wheel branch of hopper 2
Gear wheel is fixedly installed on frame 9, the gear wheel support 9, the gear wheel is close on the outer wall of hopper 2, and then improves and originally subtract
The whole service life of method micro-balance.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not make any formal to the present invention
Limitation, any simple modification, equivalent variations and modification that every technical spirit according to the present invention is made to above example,
In the range of still falling within technical solution of the present invention.
