Description

Technical Field

[0001] The utility model belongs to the technical field of hydroponic plant equipment, and more specifically relates to an anti-settling device for a main shaft of a spiral grass tower. Background Art

[0002] As a special cultivation method for forage cultivation, hydroponic forage has high water and land resource utilization efficiency, highly controllable environmental conditions, and a harmless production process without the participation of pesticides, herbicides and other chemicals. These advantages make the hydroponic forage system very suitable for harsh climatic environments, such as deserts, areas with poor soil or traditional agricultural areas with high land costs. Especially in semi-arid, arid and drought-prone areas, or some areas suffering from long-term water shortages or non-existent irrigation infrastructure, the production method of hydroponic forage can greatly improve the "difficult" problem of local livestock feed. Through hydroponics, we can produce forage including corn, barley, oats, sorghum, rye, alfalfa and triticale. In summary, hydroponic forage is a production model that can maintain continuous production throughout the year, produce high-quality fresh forage, and have high land resource utilization efficiency. It can support regional livestock farms to complete self-sufficiency in some high-quality feed, and has high practical significance and economic value.

[0003] After searching, relevant patents have been disclosed about the hydroponic forage system, and the applicant has also been committed to the research and development, design and structural optimization of the hydroponic forage system. For example, in the patent CN114793871A, a kind of enclosed rotating tower for growing forage is disclosed. The application sets a cover on the outside of the rotating tower, which can maintain the internal environment and prevent the external environment from entering, adapting to the requirements of the environment. In the patent CN114642167A, an adjustable height rotating tower for growing forage is disclosed. The application designs the tower body to be movable, so that the top of the ascending part, the connecting part and the upper end of the descending part of the rotating tower have a certain space release, and the growth space of the forage is increased as much as possible. In the patent CN114793863A, a spray irrigation system for a forage rotating tower is disclosed. The application fully considers the growth state of the forage, which can not only effectively improve the utilization efficiency of the nutrient solution, but also effectively improve the overall resource utilization efficiency of the rotating tower, and can support the continuous high-quality hydroponic forage production throughout the year, while enhancing the overall hydroponic efficiency.

[0004] The above patents all disclose relevant technical improvements on the hydroponic forage system, but there is still room for improvement. For example, after using it for a period of time, it was found that the main shaft of the rotating tower would sink to a certain extent due to the long-term vertical load, thus affecting the normal operation of the entire rotating tower.

[0035] The utility model is further described below in conjunction with specific embodiments.

[0036] like Figure 1 , Figure 2 , Figure 4 As shown, an anti-settling device for the main shaft of a spiral grass tower in this embodiment includes a mounting frame 1, a rotating component 2 and a bearing component 3. The rotating component 2 is vertically arranged, and includes an upper end 21, a lower end 22 and a rotating part 23 located between the two ends. The lower end 22 is connected to the mounting frame 1, and the upper end 21 is connected to the bearing component 3. The bearing component 3 is used to support the main shaft of the passive end of the grass tower and rotate synchronously with the main shaft.

[0037] The anti-sinking device for the main shaft of the spiral grass tower in this embodiment can support the main shaft in the vertical direction without interfering with the free rotation of the main shaft at the passive end of the grass tower through the mutual cooperation of the rotating part 2 and the bearing part 3, thereby effectively avoiding the sinking of the main shaft and ensuring the stability of the operation of the entire grass tower equipment.

[0038] Preferably, the rotating component 2 is a plane pressure bearing.

[0039] Specifically in this embodiment, the rotating component 2 is a thrust cylindrical roller bearing, which uses a thrust cylindrical roller bearing with extremely strong vertical load-bearing capacity to bear the load. It can withstand the pressure when the main shaft sinks and ensure the stability of the equipment operation; at the same time, it can also effectively avoid stress deformation of the entire anti-settling device.

[0040] refer to Figure 3As shown, in this embodiment, the mounting frame 1 includes a horizontal section 11 and a vertical section 12 connected to each other. The horizontal section 11 is used to connect the rotating component 2, and the vertical section 12 is used to connect the grass tower body.

[0041] Specifically, the horizontal section 11 includes a horizontal platform surrounded by square tubes, and a limit support plate arranged on the horizontal platform, and a mounting slot for the lower end 22 to be inserted into the limit support plate is provided. The vertical section 12 is composed of two square tubes, which are used to be welded on the main body of the grass tower.

[0042] In addition, in order to improve the structural strength of the entire mounting frame 1 , a reinforcing rib 13 is welded between the horizontal section 11 and the vertical section 12 .

[0043] In this embodiment, as an implementation method of the bearing component 3, refer to Figure 5 , Figure 7 As shown, the bearing component 3 includes a first connecting member 31 and a second connecting member 32 connected to each other. The first connecting member 31 is connected to the upper end portion 21, and the second connecting member 32 is used to connect the main shaft.

[0044] Specifically, a mounting groove 321 is provided at the top of the second connecting member 32, and a fastening hole is provided at the bottom of the mounting groove 321; of course, a corresponding fastening hole must be provided at the end of the supported spindle. When the end of the spindle is inserted into the mounting groove 321, a fastener, such as a fastening bolt, is passed through the corresponding fastening hole from the bottom of the mounting groove 321 to achieve a stable connection between the spindle and the second connecting member 32.

[0045] The second connecting member 32 has a downwardly extending mounting boss 322 at the bottom, and the first connecting member 31 has a groove 311 for the mounting boss 322 to fit into. At the same time, a mounting notch is also provided at the bottom of the first connecting member 31 for assembling the upper end 21 of the rotating component 2.

Among them, the assembly hole located on the first connecting member 31 is a blind hole, and the assembly hole located on the second connecting member 32 is a through hole. The nut 34 uses an M12 nut, which is set on the through hole of the second connecting member 32, and the two are coaxially welded. The adjusting screw 35 passes through the nut 34 and the through hole on the second connecting member 32 and then extends into the blind hole on the first connecting member 31 to realize the assembly operation between the first connecting member 31 and the second connecting member 32. At the same time, by rotating the adjusting screw 35 and utilizing the threaded transmission between the adjusting screw 35 and the nut 34, the lifting and lowering operation of the second connecting member 32 can be realized.

[0048] In addition, in order to facilitate the alignment operation of the corresponding assembly holes 33 on the first connecting member 31 and the second connecting member 32 , a clearance fit may be adopted between the groove 311 of the first connecting member 31 and the mounting boss 322 of the second connecting member 32 .
