Description

Technical Field

[0001] This utility model relates to the field of tea seedling technology, specifically to a tea seedling frame. Background Technology

[0002] Tea refers to the leaves and buds of the tea tree, which can be used to brew tea. It can refresh the mind and promote people's health, and is widely consumed. In order to better cultivate tea and harvest high-quality tea leaves, people will first cultivate seedlings on seedling racks before planting and production.

[0003] Currently, traditional tea seedling racks are usually multi-layered to increase the number of seedlings that can be raised at one time. However, each layer of such a rack is fixed and the distance between the layers cannot be adjusted, meaning it cannot be adjusted according to the different heights of the tea seedlings. Utility Model Content

[0004] The purpose of this utility model is to provide a tea seedling rack to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea seedling rack, comprising:

[0006] The base plate is equipped with casters at all four corners of its bottom.

[0007] Multiple seedling trays are distributed at equal intervals from top to bottom, and the rear sides of the multiple seedling trays are connected to a spacing adjustment mechanism.

[0008] The spacing adjustment mechanism includes multiple connecting plates, the number of which is the same as the number of seedling trays. Each connecting plate is connected to the rear side of the corresponding seedling tray. Support shafts are fixed on the left and right sides of the rear side of each connecting plate. Two intersecting movable plates are movably sleeved on the support shafts. The ends of adjacent movable plates are rotatably connected by pins. A lifting plate is fixed in the middle of the rear side of the uppermost connecting plate. An internally threaded sleeve is rotatably connected to the bottom of the lifting plate. A screw is nested in the internal thread of the internally threaded sleeve. The lower end of the screw is fixedly connected to the base plate.

[0009] Preferably, the internal threaded sleeve has multiple handles fixed at equal intervals on its side wall, which facilitates the application of force to the internal threaded sleeve, thereby rotating the internal threaded sleeve.

[0010] Preferably, limit rods are fixed on both the left and right sides of the upper rear end of the base plate, and a sliding sleeve is fixed to the rear end of the support shaft. The sliding sleeve is slidably sleeved on the corresponding limit rod, which improves the stability of the seedling tray moving up and down.

[0011] Preferably, the top ends of the two limiting rods are connected to a top plate, which improves the stability of the installation of the two limiting rods.

[0012] Preferably, support plates are fixed to both the left and right sides of the upper rear edge of the base plate, and a handle is fixed to the upper rear side of the support plate to facilitate pushing the tea seedling rack.

[0013] Preferably, the connecting plate and the seedling tray are connected by bolts, which is simple and reliable.

[0014] Preferably, the connecting plate, support shaft, movable plate, internal threaded sleeve and screw are all made of stainless steel, which has high structural strength and long service life.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By connecting a spacing adjustment mechanism to the rear of multiple seedling trays, the distance between the seedling trays can be adjusted by rotating the internal threaded sleeve on the spacing adjustment mechanism. This allows for adjustment of the distance between the seedling trays according to the different heights of the tea seedlings, making the adjustment simple, quick, time-saving, and labor-saving.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 5 The tea seedling rack shown includes:

[0027] Base plate 1, with casters 2 installed at all four corners of the bottom of base plate 1;

[0028] Multiple seedling trays 3 are distributed at equal intervals from top to bottom, and the rear sides of the multiple seedling trays 3 are connected to a spacing adjustment mechanism.

[0029] The spacing adjustment mechanism includes multiple connecting plates 4, the number of which is the same as the number of seedling trays 3. The connecting plates 4 are connected to the rear side of the corresponding seedling trays 3. Support shafts 5 are fixed on the left and right sides of the rear side of the connecting plates 4. Two intersecting movable plates 6 are movably sleeved on the support shafts 5. The ends of the adjacent movable plates 6 are rotatably connected by pins. A lifting plate 7 is fixed in the middle of the rear side of the uppermost connecting plate 4. An internal threaded sleeve 8 is rotatably connected to the bottom of the lifting plate 7. A screw 9 is nested in the internal thread of the internal threaded sleeve 8. The lower end of the screw 9 is fixedly connected to the base plate 1.

[0030] Multiple handles 10 are fixed at equal intervals on the side wall of the internal threaded sleeve 8. The handles 10 facilitate the application of force to the internal threaded sleeve 8, thereby rotating the internal threaded sleeve 8.

[0031] Limiting rods 11 are fixed on both the left and right sides of the upper rear end of the base plate 1, and a sliding sleeve 13 is fixed at the rear end of the support shaft 5. The sliding sleeve 13 is slidably sleeved on the corresponding limiting rod 11, which improves the stability of the seedling tray 3 moving up and down.

[0032] The top ends of the two limiting rods 11 are connected to the top plate 12, which improves the stability of the installation of the two limiting rods 11.

[0033] Support plates 14 are fixed to both the left and right sides of the upper rear edge of the base plate 1. A handle 15 is fixed to the upper rear side of the support plate 14 to facilitate pushing the tea seedling rack.

[0034] The connecting plate 4 and the seedling tray 3 are connected by bolts, which is simple and reliable.

[0035] The connecting plate 4, support shaft 5, movable plate 6, internal threaded sleeve 8, and screw 9 are all made of stainless steel, which has high structural strength and long service life.

[0036] In this invention, a spacing adjustment mechanism is connected to the rear side of multiple seedling trays 3. Rotating the internal threaded sleeve 8 on the spacing adjustment mechanism causes the internal threaded sleeve 8 to move up or down. When the internal threaded sleeve 8 moves, it drives the seedling tray 3 located at the top to move. The movement of the seedling tray 3 located at the top drives the movement of the other seedling trays 3 through the connection between the movable plates 6. This allows the distance between each seedling tray 3 to be adjusted, so that the distance between the seedling trays 3 can be adjusted according to the tea seedlings of different heights. The adjustment is simple, quick, time-saving and labor-saving.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
