Description

Technical Field

[0001] The invention relates to the field of auxiliary potato late blight sampling equipment, in particular to a placement rack for potato late blight sampling devices. Background Art

[0002] Potato late blight, caused by Phytophthora infestans, is a devastating oomycete disease that causes leaf and stem death and tuber rot in potatoes. The pathogen overwinters primarily as mycelium in tubers. Planting infected tubers can result in failure to germinate or death upon emergence. Some plants, upon emergence, become centrally infected. Sporangia formed in the infected areas are transported by air currents and reinfect, forming a focal point, causing the disease to spread rapidly from a single point to a larger area. Sporangia on infected leaves can also seep into the soil with rainwater or irrigation water, infecting tubers and forming diseased tubers.

[0003] Authorization announcement number CN208151373U discloses a placement rack for potato late blight sampling devices, comprising a rectangular placement box with an open front end, a placement tray, a column, and a base. The placement box is fixed to the upper end surface of the base, and the column is vertically mounted on the base, and the column is located inside the opening of the placement box; the placement tray is mounted on the column via a bearing and can rotate on the column; the utility model has a reasonable design, a simple structure, and is easy to use. It can cleverly place potato late blight sampling devices, and ensures that the placement is stable and reliable, does not take up space, and is very convenient to take and place; through the reasonable design of multiple placement trays, multiple potato late blight sampling devices can be placed simultaneously, and it is ensured that they do not interfere with each other.

[0004] However, in the above patent, the placement tray can keep rotating, and the limiting protrusions on the outer wall of the rotating placement tray are placed in the limiting grooves, which lack effective positioning, causing the placement tray to easily slide out and deflect. The structural design is not stable enough, and when the placement tray is damaged or needs to be cleaned, it is difficult to disassemble, which is not convenient to use. In this regard, we designed a placement rack for a potato late blight sampling device. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of lack of effective positioning, difficulty in disassembly and inconvenience in use, and to propose a placement rack for a potato late blight sampling device.

The handle rod is held by hand and the pressing tongue is pressed, so that the pressing tongue connected to the torsion spring is close to the inner wall of the handle rod, the steel wire rope is straightened, and the straightened steel wire rope pulls the fixed plate sliding in the U-shaped frame. At this time, the spring is stretched, and the slider slides in the slide groove to ensure the stability of the movement of the top head. At this time, the top head is separated from the socket and can be pulled out of the placement plate. On the contrary, when the placement plate is pushed out to the placement box, the pressing tongue is kept pressed. When the U shape is in the slot, the pressure on the pressing tongue is released, and the spring naturally returns to its original position, pushing the top head into the socket to form a snap connection, effectively solving the problems raised in the background technology, and realizing that multiple placement plates can simultaneously place multiple potato late blight sampling devices, and ensuring that they do not interfere with each other. The placement plates are stably and reliably placed, which is convenient for deflection, expansion and pushing in.

The set placement tray is rotatably connected to the insertion rod through the fixing sleeve and supported by the bracket. On the one hand, it plays a role in ensuring that the placement tray can rotate. On the other hand, when the placement tray is damaged or needs to be cleaned, the insertion rod can be rotated and pulled out, so that the placement tray can be disassembled and taken out to achieve cleaning and maintenance.

[0012] The beneficial effects of the present invention are: The present invention adopts a bottom plate, a placement box, a placement tray, a push head and a pulling mechanism, etc., by pressing the pressing tongue, the steel wire rope is straightened, and the spring is stretched. At this time, the push head is separated from the socket, and the placement tray can be pulled out. Conversely, when the placement tray is pushed into the placement box, the pressing tongue is kept pressed. When the U-shaped frame is located in the slot, the pressure on the pressing tongue is released, the spring is naturally reset, and the push head is pushed out into the socket to form a snap connection, which effectively solves the problems raised by the background technology, realizes that multiple placement trays can simultaneously place multiple potato late blight sampling devices, and ensures that they do not interfere with each other.
