Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry breeding environment monitoring technology, and more specifically, it relates to a poultry microbial environmental air sampler. Background Technology

[0002] In the fields of livestock and poultry breeding environment monitoring, animal disease prevention and control, and farm hygiene assessment, accurate detection of airborne microbial concentration in poultry farms is an important means of evaluating environmental quality and preventing respiratory diseases. Poultry at different growth stages have significantly different sensitivities to air quality, requiring systematic collection of air samples from different heights within the poultry house. Therefore, the sampling equipment must have flexible height adjustment capabilities and remain stable after positioning to avoid height deviation caused by vibration or airflow disturbance during sampling, which could affect data accuracy.

[0003] Traditional sampler height adjustment devices mainly use screw lifting, rack and pinion, or pin hole positioning. Screw mechanisms offer high positioning accuracy but take a long time to adjust. Rack and pinion transmissions are convenient to operate, but the meshing clearance causes slight displacement even after locking. Pin hole positioning has a simple structure but can only be adjusted in steps, which cannot meet the precise height requirements, and the insertion and removal operations are difficult. These traditional locking methods are prone to loosening and wear when subjected to the weight of the equipment and vibration loads. Especially in the humid and corrosive environment of a farm, the metal mating surfaces are prone to rusting, jamming, or increased clearance, leading to decreased locking reliability and even the safety hazard of accidental falling.

[0022] In this embodiment, during use, the height of the lifting frame 4 is adjusted by sliding the movable frame 3 along the support frame 2, thereby controlling the sampling height of the sampler body 5. At this time, the stepless rod 6 slides along the support frame 2. After adjusting to a suitable height, the limiting sleeve 14 is pushed to make the sliding sleeve 12 slide and drive multiple sets of push plates 13 to push the guide block 11. The multiple sets of guide blocks 11 drive the movable rod 9 to stretch the tension spring 19 and push the clamping plate 10 to clamp the outer wall of the stepless rod 6. At this time, multiple sets of sliding rods 17 are inserted into the unlocking hole 28. Rotating the rotating sleeve 16 drives the multiple sets of sliding rods 17 to rotate into the limiting hole 15. At this time, multiple sets of limiting blocks 18 respectively abut against both sides of the limiting sleeve 14 to limit the sliding sleeve 12. At this time, multiple sets of compression springs 29 push the positioning block 25 to abut against the positioning hole 27 to position the rotating sleeve 16.

[0030] In summary, during use or operation of the overall equipment: During use, the height of the lifting frame 4 is adjusted by sliding the movable frame 3 along the support frame 2, thereby controlling the sampling height of the sampler body 5. At this time, the stepless rod 6 slides along the support frame 2. After adjusting to a suitable height, the limiting sleeve 14 is pushed, causing the sliding sleeve 12 to slide and drive multiple sets of push plates 13 to push the guide block 11. The multiple sets of guide blocks 11 drive the movable rod 9 to stretch the tension spring 19 and push the clamping plate 10 to clamp the outer wall of the stepless rod 6. At this time, multiple sets of sliding rods 17 are inserted into the unlocking hole 28. Rotating the rotating sleeve 16 drives the multiple sets of sliding rods 17 to rotate into the limiting hole 15. At this time, multiple sets of limiting blocks 18 respectively abut against both sides of the limiting sleeve 14 to limit the sliding sleeve 12. At this time, multiple sets of compression springs 29 push the positioning block 25 to abut against the positioning hole 27 to position the rotating sleeve 16. Multiple sets of rubber pads 22 are clamped to the outer wall of the stepless rod 6 to fix the movable frame 3.

[0031] When it is necessary to unlock the stepless lever 6, rotating the rotating sleeve 16 causes multiple sets of sliding rods 17 to slide into the unlocking hole 28, releasing the contact between multiple sets of limiting blocks 18 and the outer wall of the limiting sleeve 14, so that multiple sets of tension springs 19 pull multiple sets of movable rods 9 to slide and drive the clamping plate 10 to release the clamping of the stepless lever 6. When the rotating sleeve 16 rotates, it causes multiple sets of sliders 23 to slide in the positioning sleeve 26. Through the arc-shaped design of the outer side of multiple sets of positioning holes 27 and the top of the positioning block 25, multiple sets of positioning blocks 25 are disengaged from the positioning holes 27 and squeeze the compression spring 29, so that multiple sets of positioning blocks 25 move in the multiple sets of positioning holes 27.
