Problems solved by technology

[0005] 1. It adopts extensive detection, the gas exhaled by the cow is easy to diffuse, and the distance between the cow's mouth and the gas collection pipe will also affect the test results, so the accuracy of the test results cannot be guaranteed
[0006] 2. It uses online detection, that is, the gas concentration exhaled by cows is detected on-site by a gas detector. Due to the limitation of the sensor's own performance, it is impossible to conduct a more detailed analysis of the gas exhaled by cows.

Embodiment 1

[0033] See attached Figure 1-2 , a collection device for collecting the exhaled gas of dairy cows, comprising a feeding trough 1, the cross section of the feeding trough is concave arc-shaped, the depth of the feeding trough is 30cm, and the upper port of the feeding trough is rectangular, 45cm long and 30cm wide; The upper port of the trough is provided with a circle of rubber ring 2, and the shape of the central area surrounded by the rubber ring is approximately oval, so that when the cow's mouth stretches into the feeding trough to eat, the shape of the central area surrounded by the rubber ring can be maximized. It fits the cow to a certain extent, so as to ensure that the breath exhaled by the cow stays in the feeding trough.

[0034] Further, a first humidity detection sensor 3-1 is arranged inside the feeding trough, and a second humidity detection sensor 3-2 is arranged outside the feeding trough, and the first humidity detection sensor 3-1 is preferably fixedly inst...

Embodiment 2

[0038] On the basis of Embodiment 1, further, the controller adopts 89C52 single-chip microcomputer, and the first humidity detection sensor 3-1 and the second humidity detection sensor 3-2 both adopt the WHTM-02 temperature sensor of Rylance Humidity monitoring sensor, WHTM-02 temperature and humidity monitoring sensor has four wires, the red line is VCC, the black line is GND, the yellow line is the humidity output, and the white line is the temperature output (this embodiment does not use this line), WHTM-02 temperature and humidity monitoring The yellow wire of the sensor is connected to the I / O pin of the 89C52 microcontroller (for example, the yellow wire of the first humidity detection sensor is connected to the P0.1 pin of the 89C52 microcontroller, and the yellow wire of the second humidity detection sensor is connected to the P0.2 pin of the 89C52 microcontroller. foot, image 3 due to limited size, not shown).

[0039] Further, the air pump adopts the ZQ370-02PM mi...

Embodiment 3

[0042] On the basis of Embodiment 1, furthermore, the air suction nozzle of the air suction pump is provided with a filter screen to prevent the forage in the feeding trough from entering the air suction pump.

Abstract

The invention discloses a collecting device for collecting exhaled breath of a cow and a collecting method thereof. The collecting device comprises a feeding trough, the upper port of which is provided with a rubber ring. The shape of a central region surrounded by the rubber ring can fit the cow at the greatest extent so as to ensure that exhaled breath of the cow stays inside the feeding trough.A first humidity detecting sensor is disposed inside the feeding trough, and a second humidity detecting sensor is disposed outside the feeding trough. According to a difference value of humidity detected by the first humidity detecting sensor and the second humidity detecting sensor, whether there is sufficient bovine exhaled breath in the feeding trough is judged. An air sampling device is arranged on the outer wall of the feeding trough. When there is sufficient bovine exhaled breath in the feeding trough, a certain amount of air in the feeding trough is drawn and stored in an air samplingbag. The bovine exhaled breath can be accurately collected, and the air is collected in the sampling bag for subsequent more detailed analysis in a laboratory.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry inspection and quarantine devices, and in particular relates to a collection device and a collection method for collecting exhaled gas from dairy cows. Background technique [0002] The breath exhaled by a cow can reflect the health of the cow itself. For example, the breath exhaled by a cow with a normal smell has no peculiar smell. If the exhaled breath has a foul smell, it indicates that there may be necrosis in the lungs and respiratory tract; if there is a purulent smell , it indicates that there may be abscess rupture in the lungs; if there is acetone smell, it indicates that there may be ketosis, and so on. [0003] The above method through the sense of smell is only a preliminary judgment. If you want to further qualitatively judge the gas composition exhaled by cows, you need to further analyze it through experimental instruments (the common method is to use gas chromatography, f...
