[0001] The utility model belongs to the technical field of seedling-raising racks, and particularly relates to a seedling-raising rack with an adjusting function. Background Technique

[0002] Seedling raising, that is, cultivating seedlings, is a crucial link in agricultural production. Generally, a seedling-raising rack is used. When raising seedlings, a substrate is filled in a seedling-raising container on the seedling-raising rack, and seeds or seedlings are implanted into the substrate for cultivation. However, in the prior art, the seedling-raising rack is generally fixed and non-adjustable, and it is impossible to conveniently adjust the number of layers and the single-layer height of the seedling-raising rack according to the height, type and use requirements of the seedlings, resulting in the inability to fully utilize the space of the cultivation site. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a seedling-raising rack with an adjusting function. By setting combinable and detachable seedling-raising rack combination modules, the required number of seedling-raising rack combination modules can be quickly assembled according to needs, and the distance between the lower supporting bracket and the upper supporting bracket in each group of seedling-raising rack combination modules can be conveniently adjusted steplessly and quickly, so as to adjust the distance between two adjacent seedling trays above and below, and thus flexibly meet the height requirements of seedlings of different types and different growth time periods.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A seedling-raising rack with an adjusting function, including a bottom bracket and multiple groups of seedling-raising rack combination modules. The seedling-raising rack combination module includes a lower supporting bracket and an upper supporting bracket. Lower corner fixing seats are installed at the four corners of the lower supporting bracket, and upper corner fixing seats are installed at the four corners of the upper supporting bracket. A slide rod sleeve and a screw rod sleeve are installed at the bottom of the upper corner fixing seat. A screw rod is rotatably installed at the top of the lower corner fixing seat, and a slide rod is fixedly installed. The number of the slide rods and the slide rod sleeves is three, and the number of the screw rods and the screw rod sleeves is one. The slide rod is inserted into the slide rod sleeve, and the screw rod is threadedly connected with the screw rod sleeve. A first bevel gear is fixedly sleeved on the outer side of the screw rod. A rotating shaft is rotatably installed on the side surface of the lower corner fixing seat, and a second bevel gear is fixedly sleeved on the outer side of the rotating shaft. The second bevel gear meshes with the first bevel gear. One end of the rotating shaft is connected with a crank. Sockets are provided at the top of the upper corner fixing seat and the top of the bottom bracket, and a plug rod is provided at the bottom of the lower corner fixing seat. A seedling tray is screwed inside the lower supporting bracket.

[0005] The beneficial effects of the present utility model are as follows: By providing a combinable and detachable seedling-raising rack combination module, the device can quickly assemble the required number of seedling-raising rack combination modules according to needs, and can conveniently and steplessly and quickly adjust the spacing between the lower supporting brackets and the upper supporting brackets in each group of seedling-raising rack combination modules, so as to adjust the spacing between two adjacent seedling trays above and below, and thus flexibly meet the height requirements of seedlings of different types and at different growth stages.

[0006] For the convenience of the device's constellation and storage tools:

[0007] As a further improvement of the above technical solution: Universal wheels are installed at the bottom of the bottom bracket, and a storage box is provided at the top of the bottom bracket.

[0008] The beneficial effects of this improvement are as follows: The universal wheels are used to facilitate the movement of the device, and some commonly used tools can be stored in the storage box provided at the top of the bottom bracket.

[0009] For the convenience of confirming the adjustment distance of the upper supporting bracket:

[0010] As a further improvement of the above technical solution: Scales are provided on the outer side of the sliding rod.

[0011] The beneficial effects of this improvement are as follows: The setting of the scales facilitates the confirmation of the adjustment distance of the upper supporting bracket.

[0012] For more labor-saving adjustment of the spacing between the upper supporting bracket and the lower supporting bracket:

[0013] As a further improvement of the above technical solution: The number of teeth and the size of the second bevel gear are both smaller than those of the first bevel gear.

[0014] The beneficial effects of this improvement are as follows: Since a crank is provided for increasing the moment arm, and at the same time the number of teeth and the size of the second bevel gear are smaller than those of the first bevel gear, when the second bevel gear drives the first bevel gear to rotate, due to the relationship of the tooth ratio, the moment on the second bevel gear is relatively small. With the setting of the crank, it is possible to be more labor-saving even when adjusting the spacing between the lower supporting bracket and the upper supporting bracket by rotating the crank on the seedling-raising rack combination module at a relatively lower position.

[0015] For the fixation between the socket and the plug rod:

[0016] As a further improvement of the above technical solution: Screw holes are provided on both the socket and the plug rod, and they are connected and fixed by locking bolts.

[0017] Parts not involved in this device are the same as the prior art or can be implemented by using the prior art. Description of the Drawings

The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0024] As Figures 1-4 shown, a seedling-raising rack with an adjustment function includes a bottom bracket 1 and multiple groups of seedling-raising rack combination modules 4. The seedling-raising rack combination module 4 includes a lower support bracket 5 and an upper support bracket 7. Lower corner fixing seats 6 are installed at the four corners of the lower support bracket 5, and upper corner fixing seats 8 are installed at the four corners of the upper support bracket 7. A slide rod sleeve 9 and a screw rod sleeve 10 are installed at the bottom of the upper corner fixing seat 8. A screw rod 12 is rotatably installed at the top of the lower corner fixing seat 6, and a slide rod 11 is fixedly installed. The number of the slide rods 11 and the slide rod sleeves 9 is three, and the number of the screw rods 12 and the screw rod sleeves 10 is one. The slide rod 11 is inserted into the slide rod sleeve 9, and the screw rod 12 is threadedly connected to the screw rod sleeve 10. A first bevel gear 13 is fixedly sleeved on the outer side of the screw rod 12. A rotating shaft 14 is rotatably installed on the side surface of the lower corner fixing seat 6, and a second bevel gear 15 is fixedly sleeved on the outer side of the rotating shaft 14. The second bevel gear 15 meshes with the first bevel gear 13. One end of the rotating shaft 14 is connected to a crank 17. Sockets 18 are provided at the top of the upper corner fixing seat 8 and the top of the bottom bracket 1, and a plug rod 19 is provided at the bottom of the lower corner fixing seat 6. A seedling tray 22 is screwed inside the lower support bracket 5.

[0025] By setting the combinable and detachable seedling-raising rack combination module 4, this device can quickly assemble the required number of seedling-raising rack combination modules 4 according to needs, and can conveniently and steplessly and quickly adjust the spacing between the lower support bracket 5 and the upper support bracket 7 in each seedling-raising rack combination module 4 separately, so as to adjust the spacing between two adjacent seedling trays 22 above and below, and then flexibly meet the height requirements of seedlings of different types and at different growth time periods.

[0026] Universal wheels 2 are installed at the bottom of the bottom bracket 1, and a storage box 3 is provided at the top of the bottom bracket 1.

[0027] The universal wheels 2 are used to facilitate the movement of this device, and some commonly used tools can be stored in the storage box 3 provided at the top of the bottom bracket 1.

[0028] A scale 21 is provided on the outer side of the sliding rod 11.

[0029] The setting of the scale 21 facilitates confirming the adjustment distance of the upper support bracket 7.

[0030] The number of teeth and the size of the second bevel gear 15 are both smaller than those of the first bevel gear 13.

[0031] Due to the setting of the crank 17 for increasing the moment arm, and at the same time the number of teeth and the size of the second bevel gear 15 are smaller than those of the first bevel gear 13. When the second bevel gear 15 drives the first bevel gear 13 to rotate, due to the relationship of the tooth ratio, the moment on the second bevel gear 15 is relatively small. With the setting of the crank 17, it is more labor-saving even when adjusting the spacing between the lower support bracket 5 and the upper support bracket 7 by rotating the crank 17 on the seedling-raising rack combination module 4 at a relatively lower position.

[0032] Screw holes are provided on both the socket 18 and the plug rod 19, and they are connected and fixed by a locking bolt 20.

[0033] Working principle and usage process of the utility model: When this device is in use, the installation quantity of the seedling-raising rack combination module 4 can be selected according to the usage requirements. During installation, place the bottom bracket 1 at the bottommost position. Insert the insertion rod 19 at the bottom of a group of seedling-raising rack combination modules 4 into the socket 18 at the top of the bottom bracket 1. Subsequently, insert the insertion rod 19 at the bottom of the next group of seedling-raising rack combination modules 4 into the socket 18 at the top of this group of seedling-raising rack combination modules 4, and so on, until the required quantity of seedling-raising rack combination modules 4 is installed. After completing the installation between each seedling-raising rack combination module 4, use the locking bolt 20 to fix the connected socket 18 and insertion rod 19. Subsequently, the distance between the lower supporting bracket 5 and the upper supporting bracket 7 in each seedling-raising rack combination module 4 can be adjusted according to the requirements. During adjustment, rotate the crank 17, which can drive the rotating shaft 14 to rotate. Through the rotating shaft 14, drive the second bevel gear 15 to rotate, thereby driving the first bevel gear 13 together with the screw rod 12 to rotate. Furthermore, through the threaded transmission between the screw rod 12 and the screw rod sleeve 10, drive the screw rod sleeve 10 together with the upper supporting bracket 7 to lift and lower under the support and telescopic cooperation of the sliding rod 11 and the sliding rod sleeve 9, thereby adjusting the distance between the lower supporting bracket 5 and the upper supporting bracket 7. Due to the setting of the crank 17 for increasing the moment arm, and at the same time, the number of teeth and size of the second bevel gear 15 are smaller than those of the first bevel gear 13. When the second bevel gear 15 drives the first bevel gear 13 to rotate, due to the relationship of the tooth ratio, the moment on the second bevel gear 15 is relatively small. With the setting of the crank 17, it is more labor-saving even when adjusting the distance between the lower supporting bracket 5 and the upper supporting bracket 7 by rotating the crank 17 on the seedling-raising rack combination module 4 at a relatively lower position. At the same time, the distance between the lower supporting bracket 5 and the upper supporting bracket 7 on each group of seedling-raising rack combination modules 4 can be adjusted conveniently and individually, enabling the distance between two adjacent upper and lower seedling trays 22 to be adjusted steplessly and freely, and being able to flexibly meet the height requirements of seedlings of different types and different growth time periods. At the same time, a scale 21 is set on the sliding rod 11, which is also convenient for confirming the adjustment distance. Tools commonly used can be stored in the storage box 3 at the top of the bottom bracket 1, and the device can be conveniently moved through the universal wheels 2 at the bottom of the bottom bracket 1. To sum up, by setting the detachable and combinable seedling-raising rack combination module 4, the required quantity of seedling-raising rack combination modules 4 can be quickly assembled according to the requirements, and the distance between the lower supporting bracket 5 and the upper supporting bracket 7 in each group of seedling-raising rack combination modules 4 can be adjusted individually and steplessly and quickly, thereby adjusting the distance between two adjacent upper and lower seedling trays 22, and then flexibly meeting the height requirements of seedlings of different types and different growth time periods.
