Description

Technical Field

[0001] This utility model relates to the field of soilless cultivation technology, specifically to a seedbed frame. Background Technology

[0002] Soilless cultivation is a cultivation method that does not rely on natural soil, but uses artificially prepared nutrient solutions and substrates to provide plants with the nutrients and water they need for growth. The seedbed is a facility used to cultivate seedlings, providing suitable environmental conditions for their growth.

[0003] Currently, seedbeds mainly consist of seedling trays and a frame for holding the trays, into which crop seedlings are planted. Traditional frame frames have relatively fixed positions for the trays, suitable only for trays of a single size and shape, and cannot achieve universal applicability within a certain range. Some existing seedbeds use cross-shaped crossbeams to allow the trays to slide on the frame; however, for trays with special shapes, they can easily collide and become squeezed together when placed adjacently or slid. Utility Model Content

[0004] The purpose of this utility model is to provide a seedbed frame that enhances the strength and stability of the frame, allowing the seedling trays to slide smoothly in the grooves. To achieve the above objective, this utility model adopts the following technical solution:

[0005] This utility model discloses a seedbed frame for placing seedling trays, comprising: crossbeam profiles, support columns, and connecting rods. Several crossbeam profiles are arranged in parallel, and several support columns are also arranged, with the support columns arranged vertically below the crossbeam profiles. Adjacent support columns are connected by the connecting rods.

[0006] The crossbeam profile includes a cross plate and a partition. The partition is vertically disposed on the upper surface of the cross plate, and the partition and the upper surface of the cross plate form a groove. The cavity plate is placed on the groove of the adjacent crossbeam profile and can slide back and forth along the groove.

[0007] Furthermore, the dividing part is a spacer bar, which is disposed on the central axis of the horizontal plate, and the spacer bar and the upper surface of the horizontal plate form two sliding grooves on the left and right sides. When the adjacent acupuncture trays are placed close to the spacer bar, the distance a between the tops of the acupuncture trays is greater than 0.

[0008] Preferably, the spacer strip has a hollowed-out interior.

[0009] In some other embodiments, the partition is a first partition, and a pair of first partitions are provided. The first partitions are symmetrically arranged on both sides of the central axis of the horizontal plate, and the first partitions and the upper surface of the horizontal plate form two sliding grooves on the left and right. When the adjacent acupuncture trays are placed close to the first partitions, the distance a between the tops of the acupuncture trays is greater than 0.

[0010] Furthermore, the end of the connecting rod is connected to the bottom end of the support column, and the adjacent support columns and the connecting rod form a U-shape.

[0011] Furthermore, the seedling bed frame also includes: support bars, wherein two support bars are provided, and the support bars are respectively connected to the bottom end of the support column at the end of each crossbeam profile.

[0012] Preferably, the support bar is an L-shaped bar, and the side of the support bar perpendicular to the horizontal plane is connected to the outer bottom end of the support column, while the horizontal side is connected to the ground.

[0013] Furthermore, the crossbeam profile also includes: a second partition plate, the second partition plate being vertically disposed on the lower surface of the crossbeam, and a pair of second partition plates being disposed thereon, the second partition plates forming a support column mounting groove with the lower surface of the crossbeam, and the end of the support column being connected to the support column mounting groove.

[0014] Preferably, the second partition is connected to the support column by a self-tapping screw. One side of the second partition is provided with a long groove, and the side of the second partition with the groove faces outward to install the self-tapping screw, so that the side without the groove faces inward to connect with the support column.

[0015] Preferably, the upper surface of the horizontal plate is inclined downward on both sides, and the inclination angle b ≤ 5°.

[0016] After adopting the above technical solution, the present invention has the following effects:

[0017] 1. The bed frame in this utility model improves the structure of the crossbeam profile, which enables the acupuncture trays to not interfere with each other, slide more smoothly in the groove, and reduce noise.

[0018] 2. The bed frame structure of this utility model is simple, the components are easy and efficient to install, and it has high strength, high precision and good stability, and can be adapted to acupuncture trays of different sizes and shapes within a certain range.

[0019] 3. In this utility model, the supporting columns and crossbeam profiles of the bed frame are connected and fixed by self-tapping screws, which can avoid the use of fixed plates, save production costs, and improve the convenience of bed frame installation and disassembly.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, this utility model discloses a seedbed frame for placing seedling trays 2.

[0039] The bed frame 1 includes: crossbeam profiles 11, support columns 12 and connecting rods 13. Several crossbeam profiles 11 are arranged in parallel, and several support columns 12 are also arranged. The support columns 12 are arranged vertically below the crossbeam profiles 11, and adjacent support columns 12 are connected by connecting rods 13.

[0040] Among them, combined Figure 3 and Figure 5 As shown, the crossbeam profile 11 includes a cross plate 111 and a partition. The partition is vertically disposed on the upper surface of the cross plate 111, and the partition and the upper surface of the cross plate 111 form a groove 115. The cavity plate 2 is mounted on the groove 115 of the adjacent crossbeam profile 11 and can slide back and forth along the groove 115.

[0041] In this embodiment, the dividing part is a spacer 112, which is disposed on the central axis of the horizontal plate 111. The spacer 112 and the upper surface of the horizontal plate 111 form two sliding grooves 115 on the left and right sides. When adjacent pits 2 are placed close to the spacer 112, the distance a between the tops of the pits 2 is greater than 0. Figure 6 , Figure 9 and Figure 10 As shown, when the acupuncture trays 2 are inverted trapezoidal, rectangular and trapezoidal respectively, the adjacent acupuncture trays 2 are placed close to the partition strip 112, and the distance a between the tops of the acupuncture trays 2 is greater than 0. The acupuncture trays 2 of different shapes do not interfere with each other and slide more smoothly in the slide groove 115.

[0042] At the same time, combined Figure 8 As shown, the upper surface of the horizontal plate 111 is inclined downward on both sides, and the inclination angle b ≤ 5°, so that the sewage accumulated in the chute 115 can be discharged.

[0043] Secondly, the crossbeam profile 11 also includes: a second partition 114, which is vertically disposed on the lower surface of the crossbeam 111, and a pair of second partitions 114 are provided. The second partitions 114 and the lower surface of the crossbeam 111 form a support column mounting groove 116, and the end of the support column 12 is connected to the support column mounting groove 116.

[0044] Combination Figure 7 As shown, in this embodiment, the second partition 114 is connected to the support tube 12 column by self-tapping screws 15. A long groove 1141 is provided on one side of the second partition 114, and the side of the second partition 114 with the groove 1141 faces outward to install the self-tapping screws 15, so that the side without the groove 1141 faces inward to connect with the support tube 12 column.

[0045] Furthermore, in this embodiment, the end of the connecting rod 13 is connected to the bottom end of the support column 12, and adjacent support columns 12 and connecting rods 13 form a U-shape. In some other embodiments, adjacent support columns 12 and connecting rods 13 form an H-shape or an N-shape. In some other embodiments, two connecting rods 13 are provided, which are cross-fixed between adjacent support columns 12.

[0046] Combination Figure 4 As shown, in this embodiment, the bed frame 1 further includes: support bars 14, two support bars 14 are provided, and the support bars 14 are respectively connected to the bottom end of the support column 12 at the end of each crossbeam profile 11. The provision of support bars 14 can enhance the overall stability of the bed frame 1.

[0047] Among them, the support bar 14 is an L-shaped steel bar, and the side of the support bar 14 perpendicular to the horizontal plane is connected to the outer side of the bottom end of the support column 12, while the horizontal side is connected to the ground.

[0048] Example 2

[0049] like Figure 11 and Figure 12 As shown, the difference between this embodiment and embodiment one is that the interior of the partition strip 112 is hollowed out. Compared with embodiment one, the frame wall thickness of this embodiment is uniform, which can reduce the overall weight of the crossbeam profile 11 and reduce the production cost of the crossbeam profile 11.

[0050] Example 3

[0051] The difference between this embodiment and embodiments one and two is that the partition of the beam profile is different.

[0052] like Figure 13 and Figure 14As shown, in this embodiment, the partition is a first partition 113. A pair of first partitions 113 are provided. The first partitions 113 are symmetrically arranged on both sides of the central axis of the horizontal plate 111. The first partitions 113 and the upper surface of the horizontal plate 111 form two sliding grooves 115 on the left and right. When the adjacent pits 2 are placed close to the first partition 113, the distance a between the tops of the pits 2 is greater than 0.

[0053] The partition is set as a pair of first partitions 113. Compared with the first embodiment, this embodiment can reduce the overall weight of the beam profile 11. However, compared with the second embodiment, when the partition is a first partition 113, dirt may remain in the gap between the first partitions 113, which is inconvenient to clean.

[0054] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
