Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to an agricultural planting breeding box. Background Technology

[0002] With the rapid development of modern agricultural planting technology, the requirements for precise environmental control in crop breeding are increasing. Seedling boxes, as important seedling equipment, are widely used in greenhouses, laboratories, and large-scale planting bases to provide a controllable environment for seed germination and seedling growth. Plants in the lower layers of the seedling box are prone to excessive growth or poor development due to insufficient light, resulting in low light utilization and poor uniformity, thus affecting breeding quality.

[0003] While some existing technologies offer adjustable breeding racks, most rely on manual layer-by-layer adjustment, which is cumbersome and makes it difficult to ensure the stability of simultaneous lifting and lowering of multiple layers. These racks generally suffer from complex structures, limited adjustment ranges, and unreliable locking mechanisms, making them prone to displacement during transport or operation. Therefore, developing a breeding box with convenient mobility and reliable angle adjustment is of great significance for improving space utilization, optimizing lighting conditions, increasing breeding efficiency, and raising seedling survival rates.

A vertical limiting block 20 and a horizontal limiting block 19 are welded to the outer side of one fixing block 15.

[0033] Furthermore, the lifting assembly includes a handwheel 23 mounted on the side of the housing 1 via a bearing. The handwheel 23 passes through the side wall of the housing 1 and a worm gear 9 is installed inside the housing 1. Two threaded shafts 11 are installed on both sides of the bottom surface of the housing 1. A worm wheel 10 is welded to the side wall of one threaded shaft 11. The worm wheel 10 meshes with the worm gear 9. Two synchronous sprockets 12 are welded to the side walls of the two threaded shafts 11 respectively. Two sliders 32 are threadedly connected to the two threaded shafts 11 respectively, so that the angle adjustment assembly can be lifted.

[0034] Furthermore, a bottom support plate 13 is welded between the two sliders 32, a limit block 31 is welded to the inner wall of the housing 1, the lower surface of the limit block 31 abuts against the upper surface of the bottom support plate 13, a chain is connected between the two synchronous sprockets 12, a chain is connected between the first sprocket 17 and the second sprocket 22, and a chain is connected between the third sprocket 21 and the fourth sprocket 25.

[0035] Furthermore, the cover assembly includes a front cover 3 mounted on one side of the upper surface of the housing 1 via a hinge, a fixing post 8 welded to one side of the front cover 3, a side cover 2 mounted on the other side of the housing 1 via a hinge, a fixing plate 7 mounted on one side of the side cover 2 via a hinge, and a fixing groove provided on the fixing plate 7.

[0037] Furthermore, the side of the box 1 has several ventilation holes, and the upper surface of each culture fixing plate 27 has a limiting groove, and the bottom of the limiting groove has several through holes.

[0038] Furthermore, a ratchet 28 is welded to the side wall of the first fixed shaft 16, and a pawl 29 is connected to the side of a fixed block 15 via a bearing. The ratchet 28 and the pawl 29 engage with each other, so that the culture fixing plate can be stably fixed at any tilt angle and avoid displacement.

[0039] Working principle:

[0040] Mobile positioning: By holding the handle 30 on the side of the box 1, the staff can use the wheel support columns 4 and wheels 6 installed at the four corners of the bottom to smoothly push the breeding box to the target position in the greenhouse or experimental area.

[0041] Height adjustment and synchronous lifting: Rotating the handwheel 23 drives the worm 9 to rotate. The worm 9 meshes with the worm wheel 10 to drive one threaded shaft 11 to rotate. Through the synchronous sprocket 12 and chain transmission, the other threaded shaft 11 rotates synchronously. The double threaded shaft 11 drives the slider 32 to move vertically, driving the bottom support plate 13 and the top support plate 14 to rise and fall as a whole. The limit block 31 abuts against the bottom support plate 13 to achieve mechanical limit.

[0042] Light angle adjustment and locking: Move the pawl 29 to disengage it from the ratchet 28, releasing the angle lock. Manually rotate the connecting rod 18, supported by the bearing, to rotate around the first fixed shaft 16, causing the second fixed shaft 24 and the third fixed shaft 26 welded to the connecting rod 18 to swing synchronously. The first sprocket 17 welded to the first fixed shaft 16 drives the second sprocket 22, which is welded to the second fixed shaft 24 via a chain; the third sprocket 21 of the second fixed shaft 24 is driven by a chain and welded to the fourth sprocket 25 of the third fixed shaft 26. The double-chain system rigidly connects the second fixed shaft 24, the third fixed shaft 26, and the first fixed shaft 16 with a 1:1 transmission ratio, forcing the rotation angles of the second fixed shaft 24 and the third fixed shaft 26 to be equal in real time. The cultivation fixing plate 27 is simultaneously vertically welded to the two parallel shaft plates, maintaining a constant horizontal position. The cultivation fixing plate 27 changes synchronously in vertical height and horizontal position as the support tilts. Its extreme positions are mechanically constrained by the vertical limit block 20 and the horizontal limit block 19. After the connecting rod 18 is released, the pawl 29 automatically engages with the tooth groove of the ratchet 28 under the action of gravity, achieving self-locking at any angle and ensuring the stability of the culture plate.

[0043] Environmental optimization control: The ventilation holes on the side of the chamber 1 promote natural air convection and prevent excessive humidity; the limiting groove of the culture plate collects excess water and discharges it evenly through the bottom hole to avoid water accumulation; close the front cover 3 and the side cover 2, and insert the fixing groove of the fixing plate 7 into the fixing column 8 to seal the chamber.

[0044] 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.
