Description

Technical Field

[0001] This utility model belongs to the technical field of root-blocking devices for plug seedling cultivation, and more specifically, it relates to a root-blocking device for reducing root damage in corn plug seedling cultivation. Background Technology

[0002] Most existing corn seedling trays have holes at the bottom. The trays are then placed on a soil bed. When watering, excess water enters the soil through the holes. Because plant roots are hydrotropic, when there is a lot of moisture in the soil bed, the corn roots will grow out of the bottom holes and extend into the soil. When the seedling tray needs to be removed for sowing, the roots will be damaged because they are connected to the soil bed.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a root-blocking device to reduce root damage in corn plug seedling cultivation, in order to achieve a more practical purpose. Utility Model Content

[0028] EMBODIMENT

[0029] As shown in the accompanying Figure 1 to the accompanying Figure 5 :

[0030] This utility model provides a root-blocking device to reduce root damage in corn seedling trays, including a seedling tray body 1 and an installation frame 2. The installation frame 2 includes a pair of placement rods 201, each placement rod 201 having a cavity 202. A pair of movable rods 203 are installed in the cavity 202. A crossbar 204 is installed between the movable rods 203 on the same side. A support component 205 is installed at the bottom of the crossbar 204. The crossbar 204 is connected to the placement rods 201 through a fixing mechanism 3.

[0031] The fixing mechanism 3 includes a straight groove 301 formed on the surface of the placement rod 201, the straight groove 301 extending into the chamber 202, and sliding grooves 302 formed on the upper and lower inner walls of the straight groove 301. A movable plate 303 is installed in the sliding groove 302, and a first threaded hole 304 is formed on the surface of the movable plate 303. The mechanism also includes a slot 305 formed on the surface of the movable rod 203, including an adjusting bolt 306. The threaded end of the adjusting bolt 306 rotates into the first threaded hole 304 and extends into the slot 305.

[0032] The seedling tray body 1, mounting frame 2, and fixing mechanism 3 work together to adjust the width of the mounting frame 2 according to the width of the soil bed. To adjust, loosen the adjusting bolt 306, then move the moving rod 203. Moving the moving rod 203 will move the crossbar 204 and support assembly 205. When the width of the mounting frame 2 spans the soil bed, tighten the adjusting bolt 306. Tightening the adjusting bolt 306 will compress the moving rod 203, thereby increasing the friction between the moving rod 203 and the inner wall of the chamber 202, thus securing the moving rod... After fixing the seedling tray 203, place the seedling tray body 1 on the mounting frame 2. The support component 205 keeps the mounting frame 2 away from the soil bed. When moving the moving rod 203, the adjusting bolt 306 is located within the slot 305 and is limited by the straight groove 301, thus preventing the moving rod 203 from detaching from the placement rod 201. When it is necessary to disassemble the moving rod 203, simply turn the adjusting bolt 306 to disengage it from the slot 305. Through the above design, the roots of the corn seedlings can be effectively prevented from extending into the soil bed, improving practicality.

[0033] The support assembly 205 includes a sleeve rod 20501, a rotating rod 20502 installed inside the sleeve rod 20501, the surface of the rotating rod 20502 is provided with a thread 20503 and a gripping area 20504, the sleeve rod 20501 is provided with a threaded groove that matches the thread 20503, and the bottom of the rotating rod 20502 is provided with a support foot 20505.

[0034] Through the use of the supporting assembly 205, due to the height of the soil bed may be different, in use, can be handheld holding area 20504 rotates the rotating rod 20502, thereby adjusting the height of the rotating rod 20502, in turn, to adapt to the different height of the soil bed.

[0035] The supporting assembly 205 is connected with the cross rod 204 through a detachable mechanism 4.

[0036] The detachable mechanism 4 comprises a threaded connecting piece 401 installed on the top of the sleeve rod 20501 and a second threaded hole 402 opened on the bottom of the cross rod 204, and the threaded connecting piece 401 and the second threaded hole 402 are matched.

[0037] Through the use of the detachable mechanism 4, the installation and disassembly of the supporting assembly 205 can be facilitated, thereby facilitating replacement.

[0038] The material of the seedling tray main body 1 is hard plastic, and the frame of the seedling tray main body 1 extends to the outside of the placing rod 201 and the moving rod 203.

[0039] Through the above design, the placing and taking of the seedling tray main body 1 can be facilitated.

[0040] The embodiments of the present application are given for the purpose of example and description, and are not exhaustive or limit the present application to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described in order to better illustrate the principles and practical application of the present application, and to enable those skilled in the art to understand the present application so as to design various embodiments with various modifications suitable for specific purposes.
