Abstract

The utility model relates to a full -automatic dynamic weighing device of milk cow, the device includes: RFID recognizer, fence, infrared photoelectric switch, weighting platform, weighing sensor, treater and display screen, the RFID recognizer is installed on the fence, links to each other with the treater through the data line, the fence is installed in weighting platform both sides constitution passageway, a weighing sensor is respectively placed to four angle belows of weighting platform, and four weighing sensor are connected with the treater respectively, respectively install a pair of infrared photoelectric switch in passageway entrance and exit. The utility model discloses can realize dynamic measurement, measure in the milk cow motion process, solve and measured unsafe problem because of what the milk cow motion leaded to with the static weighbridge of tradition.

Description

The full-automatic dynamic weigher of milk cow

One, technical field

The utility model relates to livestock breed aquatics apparatus field, specifically the full-automatic dynamic weigher of a kind of milk cow.

Two, background technology

The body weight of milk cow weighs the important indicator of ox bulk-growth growth, is the foundation measuring production performance, determine feed intake, nutrition supply, just join age, dosage, seed selection etc.Therefore, measurement body weight is the routine work during cowboying is produced.No matter the measuring method of traditional milk cow body weight is body measurement, or is driven on weighbridge by head by milk cow and weighs, all exist workload greatly, the problem such as not easy to operate, error is large.And overstimulation milk cow easily causes output of milk decline or miscarriage.In some modern milk cattle cultivating factories can milk cow must through passageway in the middle of place weighbridge, milk cow through out-of-date automatic Weighing.But it is inconstant for having a key issue to be milk cow pressure of symmetry bench in motion process.Therefore the resultant error recorded is very big, and reference value is extremely low.

Three, utility model content

For solving the problem, the utility model provides the full-automatic dynamic weigher of a kind of milk cow.By LOAD CELLS record milk cow advance in data, then by processor, data to be processed, finally obtain real milk cow weight data.

The full-automatic dynamic weigher of a kind of milk cow, this device comprises: RFID (radio-frequency (RF) identification) recognizer, fence, Photoelectric infrared switch, weighting platform, LOAD CELLS, processor, display screen;

Described RFID recognizer, is arranged on fence, is connected by data line with processor, RFID recognizer be worn on every cow head identity label with it with the use of, milk cow is identified.

Described fence height 1.25m, wide 1m, fence is arranged on composition passageway, weighting platform both sides; Weighting platform is used for bearing the pressure transmitting milk cow; Each placement LOAD CELLS below weighting platform four angles, four LOAD CELLS are connected with processor respectively, send the milk cow pressure data of detection to processor.

Respectively install a pair Photoelectric infrared switch in porch, passageway and exit, the often pair of Photoelectric infrared switch is mounted opposite the both sides at fence respectively; Photoelectric infrared switch is connected with processor, milk cow through time control the open and close of whole meausring apparatus respectively.

Described processor is PC or single-chip microcomputer, for the data that computing obtains from LOAD CELLS, obtains and stores real milk cow body weight.

Described display screen, is connected with processor, for showing weight data etc.

Advantage of the present invention:

1, all automatic measurement is achieved, succinct, quick, saving manpower.

2, achieve kinetic measurement, can measure in milk cow motion process, solve cause measure inaccurate problem with traditional static weighbridge because of milk cow motion.

3, specially need not drive, catch milk cow, decrease the stimulation to milk cow.

Four, accompanying drawing explanation

Five, embodiment

The utility model is arranged on milk cow must through exit, milk cow can through the passageway that surrounded by fence, fence height 1.25m, wide 1m; Weighting platform is arranged in the middle of passageway; Weighting platform is used for bearing the pressure transmitting milk cow; Each placement LOAD CELLS below weighting platform four angles, four LOAD CELLS are connected with processor respectively, send the milk cow pressure data of detection to processor.Milk cow triggers Photoelectric infrared switch one when entering passageway entrance, and the full-automatic meausring apparatus of milk cow brings into operation.Run rear RFID recognizer and be worn on milk cow RFID label tag with it and be used in conjunction with each other, each cow head is actively identified, and is transferred to processor mark.Milk cow goes on weighting platform, four LOAD CELLS (LOAD CELLS can adopt SQB-1T sensor) detected pressures changes, and send detection data to processor (processor can adopt the STM-32 single-chip microcomputer comprising memory module), single-chip microcomputer calculation process, finally obtain the true body weight of milk cow, preserve and show on a display screen.Milk cow goes down weighting platform, and trigger Photoelectric infrared switch two, the full-automatic dynamic weigher of milk cow is out of service, and milk cow walks out passageway.
