Description

Technical Field

[0001] This utility model relates to the field of seedling floating tray cleaning technology, and in particular to a rotating device for cleaning seedling floating trays. Background Technology

[0002] To reduce costs in flue-cured tobacco seedling cultivation, seedling trays need to be reused multiple times. Before each reuse, the trays must be thoroughly cleaned. Traditionally, cleaning the trays involves manual washing with a high-pressure water gun, flipping the tray after washing one side to wash the other. This method is labor-intensive, inefficient, and often results in incomplete cleaning and damage to the trays. Automatic seedling tray cleaning machines have emerged, which automatically flip the trays after washing one side and wash the other side again. However, these machines are expensive to purchase and operate, bulky, and require a large footprint, making them impractical. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a seedling floating tray cleaning and rotating device to solve the technical problems mentioned in the background art.

[0004] The objective of this utility model is achieved through the following technical solution: A rotating device for cleaning seedling float trays is characterized in that: it includes a rotating shaft, both ends of which are rotatably mounted on a support, one end of which passes through the support and is connected to a crank handle, a limiting frame is fixedly mounted on the rotating shaft, and an openable cavity is provided inside the limiting frame, the cavity being adapted to a seedling float tray, and it also includes a rinsing component for rinsing the seedling float tray in the cavity.

[0005] Furthermore, the support is a cleaning tank with an open top, the bottom of the cleaning tank is provided with a drain outlet, and the rinsing assembly is set on one side wall of the cleaning tank.

[0006] Furthermore, the flushing assembly includes several high-pressure nozzles arranged in a matrix, with the nozzles connected to a water supply pipe, which is connected to a water source via valves and a pump.

[0007] Furthermore, the limiting frame includes a frame, which includes a first rectangular frame and a second rectangular frame. The four corners of the first rectangular frame and the second rectangular frame are connected by connecting rods. A support rod is provided on the center line of the width direction of the side of the second rectangular frame away from the first rectangular frame. The rotating shaft is divided into two sections, which are coaxially connected to the two ends of the support rod. A limiting rod is provided on the center line of the length direction of the first rectangular frame. One end of the limiting rod is hinged to the first rectangular frame, and the other end is detachably connected to the first rectangular frame.

[0008] The beneficial effects of this utility model are: The seedling float cleaning and rotating device proposed in this utility model has a seedling float placed in the cavity of a limiting frame. The handle drives the rotating shaft to rotate so that one side of the seedling float faces the rinsing component, which then rinses that side. Then, the handle drives the rotating shaft to rotate 180° so that the other side of the seedling float faces the rinsing component, which then rinses that side, thus completing the rinsing of the seedling float. This device has low manufacturing cost, low operating cost, small size, and small footprint.

[0009] When the support frame is a top-opening cleaning tank and the rinsing components are installed inside the cleaning tank, the device is a single unit, which is easy to transport and easy to collect cleaning water.

[0010] The rinsing assembly includes several high-pressure nozzles arranged in a matrix, which can improve the cleaning efficiency of the seedling trays.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0017] Example 1 like Figure 1-3The seedling tray cleaning and rotating device shown includes a cleaning tank 1 with an open top and a drain outlet at the bottom to centrally discharge cleaning water and prevent splashing. A rotating shaft 2 is installed inside the cleaning tank 1, with its two ends rotatably mounted on the front and rear side walls of the cleaning tank 1 via bearings. The front and rear side walls of the cleaning tank 1 serve as supports for the rotating shaft 2. The rotating shaft 2 passes through the rear side wall of the cleaning tank 1 and is connected to a crank handle 3; cranking the handle 3 rotates the rotating shaft 2. A limiting frame 4 is fixedly installed on the rotating shaft 2. The limiting frame 4 has an openable cavity inside, which is adapted to a seedling tray. The limiting frame 4 has many structural forms. For example, the limiting frame 4 includes a frame, which includes a first rectangular frame 5 located at the top and a second rectangular frame 6 located at the bottom. The four corners of the first rectangular frame 5 and the second rectangular frame 6 are connected by connecting rods 7. A support rod 8 is provided on the center line of the width direction on the lower side of the second rectangular frame 6. The rotating shaft 2 is divided into two sections, and the two sections of the rotating shaft 2 are coaxially connected to the two ends of the support rod 8. The first rectangular frame 5, the second rectangular frame 6, the four connecting rods 7, and the support rod are all included. The space between 8 is a cavity. A limiting rod 9 is provided on the center line of the length direction of the first rectangular frame 5. One end of the limiting rod 9 is hinged to the left side of the first rectangular frame 5 through a hinge shaft, and the other end is detachably connected to the right side of the first rectangular frame 5 through a locking structure 10. The hinge shaft is parallel to the first rectangular frame 5. The locking structure 10 includes a locking rod that is vertically rotatably set on the first rectangular frame 5. The end of the locking rod is vertically connected to one end of a strip-shaped limiting block. When the locking rod is rotated to a certain position, the limiting block can restrict the limiting rod 9 from rotating relative to the frame. When the locking rod is rotated 180°, the limiting rod 9 can rotate upward relative to the frame. A rinsing assembly 11 is provided on the left side wall of the cleaning tank 1 to rinse the seedling floating trays in the cavity. The rinsing assembly 11 includes several high-pressure nozzles 12 arranged in a matrix. The several high-pressure nozzles 12 are connected to a water supply pipe 13. The water supply pipe 13 is connected to a water source through a valve and a pump. The valve is located at the front end of the cleaning tank 1.

[0018] The seedling float cleaning and rotating device proposed in this utility model involves holding the limiting frame 4 with one hand and rotating the locking rod with the other hand to move the limiting block away from the limiting rod 9. Rotating the limiting rod 9 upwards opens the cavity, allowing a seedling float to be placed inside. Rotating the limiting rod 9 downwards causes its end to overlap the first rectangular frame 5. Rotating the locking rod restricts the upward rotation of the limiting rod 9. Then, cranking the handle 3 rotates the shaft 2, aligning one side of the seedling float with the rinsing component 11, which then rinses that side. Cranking the handle 3 rotates the shaft 180°, aligning the other side of the seedling float with the rinsing component 11, which then rinses that side, completing the rinsing process. The cavity of the limiting frame 4 is then opened, and the seedling float is removed, completing the cleaning process. This device has low manufacturing and operating costs, is small in size, and occupies little space. The rinsing assembly includes several high-pressure nozzles 12 arranged in a matrix, which can improve the cleaning efficiency of the seedling trays.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
