An agricultural seedling raising device

Abstract

This utility model discloses an agricultural seedling raising device, including seedling trays, sprockets, and chains. The device has symmetrically fixed slide rails on both ends of the frame, with five seedling trays slidably connected to these rails. Both sides of the frame are equipped with linkage mechanisms, each including two rotating shafts. Four sprockets with diameter ratios of 1:2:3:4 are sequentially fixed to the rotating shafts. Chains are connected between corresponding pairs of sprockets, and these chains are sequentially fixed to the four upper seedling trays via connecting blocks. The lower seedling trays are stacked directly on the bottom of the frame, with their positions fixed. The four upper seedling trays are connected to corresponding chains. When the rotating shafts rotate, the sprockets of different diameters drive different chains to lift the seedling trays by different lifting distances, causing the seedling trays to spread out at equal intervals, creating a synchronous adjustment effect.

Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, specifically an agricultural seedling device. Background Technology

[0002] Smart agriculture is the intelligent economy within agriculture, a specific manifestation of the intelligent economy in agriculture. Smart agriculture refers to the integration of modern science and technology with agricultural planting. In the cultivation of various crops, seedlings need to be nurtured before being transplanted into the soil to ensure survival rates. Seedling racks are needed during the nurturing process, and these racks come in various forms, including single-layer, double-layer, and multi-layer. Due to the current scarcity of land, multi-layer seedling racks are generally chosen to make effective use of production space.

[0003] In the existing smart agricultural seedling raising devices, the height of the trays is not adjustable and the spacing between the trays is fixed. When the seedlings grow to a certain height, they will hit the trays and need to be transplanted to seedling racks with a larger tray spacing. In addition, the seedlings of different crops have different heights, requiring the purchase of equipment with different spacing, which is not very practical.

[0004] A search revealed a patent document with publication number CN 222235865 U, which discloses a smart agricultural seedling raising device that addresses the aforementioned problems. While the height of the trays in the existing technology is adjustable, the conditions for each tray are operated independently, affecting the variability of the operation. Therefore, a new agricultural seedling raising device is proposed to optimize the aforementioned existing technology. Utility Model Content

[0005] The purpose of this invention is to provide an agricultural seedling raising device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An agricultural seedling raising device includes a frame. Slide rails are symmetrically fixedly connected to both ends of the frame, and five seedling trays are slidably connected to the slide rails. A linkage mechanism is provided on both sides of the frame. Each linkage mechanism includes two rotating shafts, and four sprockets are sequentially fixedly connected to the rotating shafts. The diameter ratio of the four sprockets is 1:2:3:4. A chain is connected between corresponding pairs of sprockets for transmission. The chain is sequentially fixedly connected to the four seedling trays above via connecting blocks. The diameter of the sprockets corresponding to the chains connected to the four seedling trays above increases sequentially from bottom to top. The seedling trays at the bottom are directly stacked at the bottom of the frame.

[0007] As a further embodiment of this utility model: a worm gear is fixedly connected to each of the rotating shafts at the top, and a worm is connected to the outer side of the worm gears on the rotating shafts of the two linkage mechanisms. The two ends of the worm are rotatably mounted on end plates, and the end plates are fixedly connected to the frame. A motor is fixedly mounted on one of the end plates corresponding to the end of the worm, and the motor is fixedly connected to the corresponding end of the worm.

[0008] As a further improvement of this utility model, the bottom of the frame is symmetrically and fixedly equipped with support legs, which provide stable support for the frame.

[0009] As a further improvement of this utility model: the seedling tray has a placement cavity, in which multiple seedling trays adapted to it are evenly placed. The seedling trays are provided with honeycomb panels adapted to them. The lower surface of the honeycomb panels is in contact with the bottom surface of the seedling tray to prevent plant roots from getting tangled in the gap between the honeycomb panels and the seedling tray.

[0010] As a further improvement of this utility model, a supplementary light is fixedly installed on the inner top of the frame and the bottom surface of the four seedling trays above. When it is cloudy or there is insufficient light, the supplementary light is turned on to supplement the light of the seedlings, thus ensuring the stability of seedling cultivation and growth.

[0011] As a further improvement of this utility model: the slide rail is provided with fixing holes at equal intervals, and the seedling tray is threaded with fixing bolts at the corresponding fixing holes. The fixing bolts are inserted into the corresponding fixing holes and are adapted to the fixing holes. The seedling tray is provided with threaded holes for threaded connection of the fixing bolts.

[0012] As a further improvement of this utility model, both the motor and the supplementary light are externally connected to a power supply and a switch.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The bottom seedling tray of this utility model is fixed in position, and the four seedling trays above are connected to the corresponding chains. When the rotating shaft rotates, different chains are driven by sprockets of different diameters to lift the seedling trays at different lifting distances, so that the spacing between the seedling trays is evenly expanded, forming a synchronous adjustment effect.

[0014] 2. After the position of the seedling tray is adjusted, the height of the seedling tray can be fixed by inserting fixing bolts into the fixing holes, thereby reducing the load on the chain when it is not driven. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-4 In this embodiment of the present invention, an agricultural seedling raising device includes a frame 1. Slide rails 2 are symmetrically fixedly connected to both sides of the frame 1. Five seedling trays 3 are slidably connected to the slide rails 2. The seedling trays 3 have slots adapted to the slide rails 2. Linkage mechanisms 4 are provided on both sides of the frame 1. Each linkage mechanism 4 includes two rotating shafts 5. Four sprockets 6 are sequentially fixedly connected to the rotating shafts 5. The diameter ratio of the four sprockets 6 is 1:2:3:4. Chains 7 are connected to the corresponding two sprockets 6 for transmission. The chains 7 are sequentially fixedly connected to the four seedling trays 3 above via connecting blocks. The diameter of the sprockets 6 corresponding to the chains 7 connected to the four seedling trays 3 above increases sequentially from bottom to top. The seedling trays 3 at the bottom are directly stacked at the bottom of the frame 1.

[0022] The bottom seedling tray 3 is fixed in position, and the four seedling trays 3 above are connected to the corresponding chains 7. When the rotating shaft 5 rotates, the different chains 7 are driven by the sprockets 6 of different diameters to lift the seedling trays 3 at different lifting distances, so that the spacing of the seedling trays 3 is evenly spread out, forming a synchronous adjustment effect.

[0023] A worm gear 8 is fixedly connected to each of the top rotating shafts 5. The outer sides of the worm gears 8 on the rotating shafts 5 of the two linkage mechanisms 4 are connected to a worm 9. The two ends of the worm 9 are rotatably mounted on the end plates 10. The end plates 10 are fixedly connected to the frame 1. A motor 11 is fixedly mounted on one of the end plates 10 corresponding to the end of the worm 9. The motor 11 is fixedly connected to the corresponding end of the worm 9.

[0024] The motor 11 drives the worm gear 9, and at the same time, the two worm wheels 8 drive the two rotating shafts 5, so that the two linkage mechanisms 4 operate synchronously.

[0025] The rotating shaft 5 is driven by the worm gear 8 and the worm 9, and the self-locking of the worm gear and the worm can create a stopping effect.

[0026] Support legs 12 are symmetrically fixedly installed at the bottom of frame 1, providing stable support for frame 1.

[0027] The seedling tray 3 has a placement cavity, in which multiple seedling trays 13 that are adapted to it are evenly placed. The seedling tray 13 has a honeycomb plate 14 that is adapted to it. The lower surface of the honeycomb plate 14 contacts the bottom surface of the seedling tray 13 to prevent plant roots from getting tangled in the gap between the honeycomb plate 14 and the seedling tray 13.

[0028] Multiple seedling trays 13 are set on the seedling rack 3 to facilitate the removal of the whole seedling after seedling cultivation.

[0029] A supplemental light 15 is fixedly installed on the inner top of the frame 1 and on the bottom of the four seedling trays 3 above. When it is cloudy or there is insufficient light, the switch of the supplemental light 15 is turned on to supplement the light of the seedlings, ensuring the stability of the seedling cultivation and growth.

[0030] The slide rail 2 has equally spaced fixing holes 16. The seedling tray 3 has a fixing bolt 17 threadedly connected to the fixing hole 16. The fixing bolt 17 is inserted into the corresponding fixing hole 16 and is adapted to the fixing hole 16. The seedling tray 3 has a threaded hole for threaded connection of the fixing bolt 17.

[0031] After the position of the seedling tray 3 is adjusted, the height of the seedling tray 3 can be fixed by inserting the fixing bolt 17 into the fixing hole 16, thereby reducing the load on the chain 7 when it is not driven.

[0032] Both the motor 11 and the supplementary light 15 are externally connected to a power supply and a switch.

[0033] The working principle of this utility model is as follows: In use, the overall frame 1 is placed on the ground via support legs 12. A honeycomb panel 14 can then be placed inside the seedling tray 13, and the planted seedling tray 13 is placed inside the seedling support frame 3 for seedling cultivation. During cloudy days or when sunlight is insufficient, the supplemental lighting 15 is turned on to provide additional light to the seedlings, ensuring the stability of their cultivation and growth. As the seedlings grow, the worm gear 9 is driven by the motor 11, which in turn drives two rotating shafts 5 via two worm wheels 8, causing the two linkage mechanisms 4 to operate synchronously. When the rotating shafts 5 rotate, different chains 7 are driven by sprockets 6 of different diameters to lift the seedling support frame 3 at different lifting distances, ensuring that the spacing of the seedling support frame 3 is evenly distributed, creating a synchronized adjustment effect. After the position of the seedling support frame 3 is adjusted, the height of the seedling support frame 3 can be fixed by inserting fixing bolts 17 into fixing holes 16, reducing the load on the chains 7 when not in use.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
