Description

Technical Field

[0001] This utility model relates to a pressing frame, and more particularly to a seedling tray pressing frame. Background Technology

[0002] Before use, seedling trays need to be thoroughly cleaned and disinfected. Technical specifications require that seedling trays be soaked in a disinfection tank for more than 20 minutes. However, since the seedling trays are made of foam, the buoyancy of the water will seriously affect the quality of cleaning and disinfection. Therefore, a pressure frame is needed to submerge the seedling trays in the disinfectant.

[0003] A seedling tray pressing frame, as disclosed in Chinese Patent Publication No. CN222110554U, is placed in a seedling tray disinfection tank. The pressing frame includes a first frame and a second frame connected together. Multiple adjustment and fixing units are respectively provided on the first and second frames, and limit plates are installed on each of the adjustment and fixing units. The first and second frames are connected to the edge of the disinfection tank through the limit plates. The bottoms of the first and second frames are in contact with the seedling trays, which are submerged in the disinfection tank. This pressing frame can assist in completely immersing the seedling trays in the disinfection tank, improving the disinfection quality.

[0004] Some problems were found when using the existing seedling tray pressing frame. First, although the limiting plate can effectively suspend and support the pressing frame in the disinfection pool, it takes two people to lift the pressing frame out after the seedling trays are disinfected. Also, after it is lifted out and placed on the ground, it will occupy a lot of space. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a seedling tray pressing frame, including a disinfection pool 9, two pressing plates 1 are symmetrically arranged in the disinfection pool 9, and a telescopic connecting rod 101 is connected between the two pressing plates 1. One of the pressing plates 1 has hinge columns 2 rotatably installed on both sides via shafts. The upper end of the hinge column 2 has a threaded hole 201. A threaded adjusting rod 302 is threadedly installed in the threaded hole 201. A fixed foot 3 is rotatably connected to the threaded adjusting rod 302. A fixed pin hole 301 is opened in the fixed foot 3. A lifting lug 104 is fixedly connected to the other pressing plate 1. A cable 4 is wound on the lifting lug 104.

[0020] In this embodiment, the fixing foot 3 can be fixed to the edge of the disinfection pool 9 by using pins or bolts through the fixing pin holes 301. The two pressure plates 1 and the telescopic connecting rod 101 are combined to form a pressure frame. Since the length between the telescopic connecting rods 101 is adjustable, the distance between the two pressure plates 1 is also adjustable, so that the length of the pressure frame can be adjusted according to the size of the disinfection pool 9. The lifting lug 104 is attached to the cable 4. By using the cable 4 and the lifting lug 104 in cooperation, one end of the pressure frame can be pulled. The other end of the pressure frame is supported by the threaded adjusting rod 302 and the hinge column 2, so that the pressure frame is suspended inside the disinfection pool 9. The seedling tray is pressed into the disinfectant in the disinfection pool 9. After the seedling tray is disinfected, one end of the pressure frame can be pulled by the cable 4. Since the pressure plate 1 is rotatably connected to the hinge column 2 through the shaft, the pressure frame is rotatably connected to the hinge column 2. At this time, pulling the front end of the pressure frame will drive the pressure frame to rotate to a vertical position. At this time, the seedling tray can be easily removed. At the same time, the vertical pressure frame will not occupy a lot of space.

[0021] In order to achieve the purpose of adjusting the distance between the two pressure plates 1, the device adopts the following technical solution: a telescopic rod is connected between the two pressure plates 1. The telescopic rod includes a threaded sleeve 102 and a threaded post 103. One end of the threaded post 103 is threadedly installed in the threaded sleeve 102. One end of the threaded sleeve 102 is fixedly connected to the telescopic connecting rod 101. The other telescopic connecting rod 101 is rotatably connected to the threaded post 103. A knob is fixedly connected to the threaded post 103.

[0022] The threaded column 103 can be rotated by the knob. The rotation of the threaded column 103 will adjust its length inside the threaded sleeve 102, thereby adjusting the overall length of the telescopic rod. The two ends of the telescopic rod are connected to two pressure plates 1 respectively, so the telescopic rod can drive the pressure plates 1 to move and adjust the distance between the two pressure plates 1.

[0023] In order to achieve the purpose of the support frame being located inside the disinfection pool 9, the device adopts the following technical solution: a connecting plate 303 is fixed between the two fixed feet 3, and a pile 304 is fixed on the connecting plate 303. The pile 304 and the cable 4 cooperate with each other.

[0024] By using the pile 304 and cable 4 in conjunction, after the pressure frame is placed inside the disinfection pool 9, the other end of the cable 4 is wrapped around the pile 304, thus using the cable 4 to keep the other end of the pressure frame suspended in the air. Figure 4 As shown.

[0025] The working principle and usage process of this utility model are as follows: When in use, a pin or bolt is used to pass through the fixing pin hole 301 to fix the fixing foot 3 to the edge of the disinfection pool 9. Then, rotating the threaded adjustment rod 302 can drive the hinge column 2 to move and adjust the depth of the pressure plate 1 in the disinfection pool 9. Rotating the fixing pin hole 301 can adjust the length of the telescopic rod and adjust the overall length of the pressure frame. The pressure frame is then placed inside the disinfection pool 9. Using the weight of the pressure frame itself, the seedling tray is pressed into the disinfectant solution. After disinfection, the cable 4 wrapped around the column 304 is removed. Pulling the cable 4 will drive the pressure frame to rotate to a vertical position, at which point the seedling tray can be easily removed.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
