Description

Technical Field

[0001] This utility model relates to the field of crop cultivation technology, and in particular to a crop cultivation rack. Background Technology

[0002] Crop seedling cultivation is a crucial step in agricultural production. Scientific seedling cultivation techniques can improve seedling quality, shorten the growth cycle, and increase yield. Crop seedling cultivation can be categorized into open-field cultivation and greenhouse cultivation based on environmental control. Greenhouse cultivation typically requires crop cultivation racks, and to save space, these racks are usually divided into multiple seedling layers along their height. Each layer contains a seedling substrate for cultivating the crop, and seedlings are planted on the substrate within each layer.

[0003] However, due to the relatively small space between each seedling layer, the operating space is limited when fertilizing, spraying pesticides, and performing other daily management tasks on the seedlings, making the management work more difficult. This undoubtedly increases the difficulty of the work and thus has a certain impact on the quality of the work. Moreover, the height of each seedling layer is mostly fixed, but the height of different types of crop seedlings varies. Therefore, traditional cultivation racks are still difficult to adapt and adjust the height of the seedling layers according to different types of crop seedlings, resulting in limited flexibility. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of the limited space of each seedling layer on the cultivation rack in the existing technology, which affects daily management and the difficulty in adjusting the height of each seedling layer.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1 and Figure 2 A crop cultivation rack includes several cultivation support units 1 stacked along the height direction. Each support unit 1 includes a support frame 11 and several adjustable-length support legs 15 disposed on the support frame 11. The support frame 11 is horizontally arranged, and the support legs 15 are vertically arranged. The several support legs 15 are distributed in a rectangular array. The lower end of the support leg 15 located on the bottom support unit 1 is provided with a walking wheel 18, which makes the cultivation rack easier to move. In order to improve the support stability of the bottom support unit 1, a support beam 19 can be fixed between two adjacent support legs 15.

[0032] Reference Figure 3 The support frame 11 is slidably connected to a support frame 12 for supporting crops in the horizontal direction. Specifically, the support frame 12 slides along the width direction of the support frame 11. Multiple support frames 12 can be set on each support frame 11 as needed, and the multiple support frames 12 are divided into two groups that are symmetrical front and back.

[0033] Reference Figure 5 The upper surface of the support frame 12 has a recessed placement cavity, in which a cultivation box 17 is placed and crops are planted.

[0034] Reference Figure 3 and Figure 4 A slide rail 13 is fixedly connected to the support frame 11, and the bearing frame 12 is slidably connected to the slide rail 13.

[0035] Each support frame 12 is provided with a slide rail 13 between its two sides and the support frame 11. The slide rail 13 is hollow inside and has a through groove 1301 on its outer surface along the length direction. The side of the support frame 12 is inserted into the slide rail 13 and slides through the through groove 1301.

[0036] Reference Figure 4 and Figure 6 The slide rail 13 is provided with a locking assembly 14 for fixing the support frame 12. The locking assembly 14 includes a limiting bolt 1401 and a nut 1402. The nut 1402 is welded to the upper surface of the slide rail 13. The limiting bolt 1401 is threaded onto the nut 1402. One end of the limiting bolt 1401 is inserted into the slide rail 13 and pressed tightly against the upper surface of the support frame 12, thereby fixing the support frame 12 onto the slide rail 13 to ensure the stability of the support frame 12.

[0037] The upper surface of the support frame 12 is fixedly connected to the slide rail 13 with a first limiting protrusion 1201. When the support frame 12 is pulled outward, the limiting bolt 1401 can block the first limiting protrusion 1201, thereby preventing the support frame 12 from sliding completely out of the slide rail 13.

[0038] The upper surface of the support frame 12 is fixedly connected to the second limiting protrusion 1202 in front of the slide rail 13. When the support frame 12 is pushed to slide inward back to its original position, the second limiting protrusion 1202 will contact the end of the slide rail 13, and the position of the support frame 12 can be restricted and positioned at this time.

[0039] The lower surface of the support frame 12 is provided with several first rollers 1203 on both sides, which abut against the inner bottom wall of the slide rail 13. The upper surface of the support frame 12 is provided with second rollers 1204 on both sides, which abut against the inner top wall of the slide rail 13. When the support frame 12 slides on the slide rail 13, the first rollers 1203 and the second rollers 1204 roll along the inner surface of the slide rail 13 to reduce the friction between the support frame 12 and the slide rail 13, avoid excessive wear, and ensure the service life of related components.

[0040] Reference Figure 3 and Figure 7 The support leg 15 includes a sleeve 1501 and an insert rod 1502 that slides inside the sleeve 1501. The sleeve 1501 is provided with a fixing component 3 that is connected to the insert rod 1502.

[0041] Reference Figure 8 The fixing component 3 includes a fixing seat 301 fixedly connected to the outer surface of the sleeve 1501 and a pin 302 slidably connected to the fixing seat 301. A return spring 303 is connected between the fixing seat 301 and the pin 302.

[0042] The fixing component 3 also includes a plurality of insertion holes 304 formed on the outer surface of the insertion rod 1502. The plurality of insertion holes 304 are arranged along the length direction of the insertion rod 1502, and the pin 302 is inserted into one of the insertion holes 304.

[0043] Reference Figure 3 and Figure 7 An assembly structure 16 is provided between the support legs 15 on two adjacent support units 1.

[0044] The assembly structure 16 includes a plug end 1601 located at the lower end of the plug rod 1502. The plug end 1601 is inserted into the lower sleeve 1501, and the limiting rib plate 1602 abuts against the upper end of the lower sleeve 1501.

[0045] The assembly structure 16 also includes a limiting rib plate 1602 fixed between the plug end 1601 and the plug rod 1502 and a connecting rib plate 1603 fixed to the upper end of the sleeve 1501. The limiting rib plate 1602 and the connecting rib plate 1603 on the lower sleeve 1501 are detachably connected. Specifically, they can be connected by bolts.

[0046] In this invention, the support units 1 are stacked and assembled from bottom to top to form a unit as shown in the attached figure. Figure 1 During the assembly of the cultivation rack shown, several plug-in ends 1601 on the upper support unit 1 are inserted into the upper ends of several sleeves 1501 on the lower support unit 1 until the limiting rib plate 1602 contacts the connecting rib plate 1603. Then, the limiting rib plate 1602 and the connecting rib plate 1603 are bolted together to complete the assembly of the cultivation rack. As can be seen from the above, the assembly of the cultivation rack is convenient and easy to operate, which can reduce the difficulty of setting up and installing the cultivation rack to a certain extent. Moreover, users can also purchase the corresponding number of support units 1 according to their own needs, so that the cultivation rack can meet and adapt to the different needs of different users and improve its flexibility.

[0047] Furthermore, when it is necessary to adjust the height of the corresponding cultivation space, this can be achieved by adjusting the height of each support leg 15 before assembling the cultivation rack. During adjustment, first pull the pin 302 outward to disengage it from the insertion hole 304 on the pin rod 1502. During this process, the pin 302 can compress the return spring 303 to a certain extent. Then, adjust the extension and retraction of the pin rod 1502 on the sleeve 1501 as needed, and ensure that the pin 302 is inserted into other corresponding insertion holes 304 under the rebound force of the return spring 303. This will fix the pin rod 1502 and the sleeve 1501, thereby achieving the purpose of adjusting the height of the support leg 15. This allows for adjustment of the spacing between two adjacent support frames 11, enabling users to adapt the height of the cultivation space according to the seedlings of different crops.

[0048] After the cultivation rack is set up, crops are planted on the cultivation box 17 and placed in the placement cavity on the support frame 12. When irrigation, spraying, transplanting, or other management work is required, the limiting bolt 1401 can be loosened first, allowing its lower end to detach from the support frame 12. Then, the support frame 12 can be pulled outward to slide a certain distance along the slide rail 13, thereby pulling the crops on the upper part of the support frame 12 outward. At this time, the external space will be more spacious, making it very convenient to perform corresponding operations on the crops, thus making the daily management of crops more convenient. After the work is completed, the support frame 12 is pushed back to its original position, and the limiting bolt 1401 is tightened to press it back tightly onto the upper surface of the support frame 12, thus fixing the support frame 12 on the slide rail 13.
