A device for detecting viable pathogenic bacteria

Abstract

This invention provides a pathogen live bacteria detection device, belonging to the field of corn southern rust detection technology. The device includes a housing with a lead screw rotatably connected to the lower inner wall of the housing; a lead screw nut threaded onto the circumferential surface of the lead screw; multiple placement shells fixedly connected to the circumferential surface of the lead screw nut; and a rotating groove within the housing. The multiple placement shells allow for the placement of bacterial culture devices such as petri dishes. When the devices inside the placement shells need to be retrieved, a knob is manually turned, causing a rotating rod and a second gear to rotate. The rotational force is then transmitted to the rotating shaft and the lead screw via the meshing groove and the first gear. This causes the lead screw nut, threaded onto the circumferential surface of the lead screw, to lift the multiple placement shells to the outside of the housing, facilitating the retrieval of the multiple petri dishes and other bacterial culture equipment inside the shells, thus improving the convenience of retrieval and placement.

Description

Technical Field

[0001] This utility model belongs to the field of corn southern rust detection technology, specifically relating to a pathogen live bacteria detection device. Background Technology

[0002] Southern rust of maize is the most common disease in tropical and subtropical maize-growing areas. It spreads rapidly and severely affects yield, making it more dangerous than common maize rust. The pathogen overwinters in maize-growing areas along the southern coast during winter. During the growing season, it spreads over long distances from south to north via urediniospores with warm and humid air currents. It is distributed in Hainan and Taiwan provinces of China, but in recent years it has also occurred on a large scale in some northern regions, showing a trend of spreading northward. The pathogen produces urediniospores, which are spread by wind and rain, causing damage from various places. The pathogen cannot survive for a long time without being separated from the host plant. The symptoms are similar to those of common rust, with small, discolored spots initially appearing on the leaves, which quickly develop into yellowish-brown raised pustules, i.e., the uredinia of the pathogen.

[0003] When detecting southern rust in maize, it is necessary to culture the bacteria in the maize. Most bacteria can be cultured artificially, that is, inoculated onto a culture medium to allow them to grow and reproduce. The cultured southern rust bacteria are then used for research, identification, and application.

[0004] However, most of the live bacteria culture media currently available on the market for live bacteria testing are inconvenient to store and retrieve, making it impossible to accurately locate and retrieve or place the required culture media, causing serious inconvenience to staff.

[0045] In a specific embodiment of this utility model, the housing 1 is made of 304 stainless steel. The lead screw 10 is vertically installed at the center of the housing 1 via bearings. Four sets of mounting shells 17 are welded to the outer circumference of the lead screw nut 16. Each set can insert multiple standard petri dishes. The mounting shell 2 is fixed to the right side of the housing 1. The second gear 9 inside it meshes with the first gear 8. The driving rod 13 extends out from the driving groove 11 on the side wall of the housing 1.

In actual operation, rotating the knob 3 counterclockwise activates the second gear. 9 drives the first gear 8 to rotate the lead screw 10, causing the lead screw nut 16 to rise. As it rises, the end cover 5 rises and opens synchronously through the cooperation of the drive rod 13, drive groove 11, push rod 14, and push block 15, allowing the inoculated culture dish to be inserted into the placement shell 17. Then, the knob 3 is rotated in the opposite direction to move multiple components in the opposite direction, placing the lead screw nut 16, multiple placement shells 17, and the culture dishes inside into the box 1 to prevent contamination.

The diameter of the two anti-detachment blocks 19 is larger than the diameter of the two limit rods 18 respectively.

[0047] In this embodiment: a folded sealing plate 12 is bonded between the upper inner wall of the drive groove 11 and the top of the drive rod 13. The folded sealing plate 12 is made of silicone and has a Z-shaped corrugated structure. When the drive rod 13 rises and falls, the folded sealing plate 12 extends and retracts accordingly, always covering the gap of the drive groove 11 to prevent external contaminants from entering the box 1. Two limit rods 18 made of stainless steel are symmetrically welded to the bottom of the box 1. Two copper limit rings are welded to both sides of the screw nut 16 and are fitted onto the outer circumference of the limit rod 18 and slide in fit. A nylon anti-detachment block 19 is hot-pressed to the top of the limit rod 18 to prevent the screw nut 16 from rising excessively and detaching from the limit rod 18.
