Description

Technical Field

[0001] The invention relates to the technical field of agricultural facilities, and in particular to a greenhouse cultivation trough system with a shock-absorbing effect. Background Art

[0002] Greenhouse cultivation troughs are trenches in greenhouses that are filled with substrates or nutrient solutions and used to cultivate crops. According to the installation mode of the cultivation troughs, they are divided into two types: suspended type and ground-supported type. The suspended cultivation trough refers to a cultivation mode in which the cultivation trough is suspended on the truss beam of the greenhouse with a steel wire rope. The root temperature of the plant that is off the ground is not affected by the surface temperature, which is conducive to the reasonable regulation of the root temperature and creates a more suitable growth environment for crops. The lack of a support on the ground is conducive to daily cleaning in the greenhouse. However, the weight of the cultivation trough, crops, and the overall supporting facilities is borne by the greenhouse structure, and its mass cannot be ignored. When the greenhouse is subjected to seismic excitation and produces horizontal vibrations, a large inertial force will be generated, resulting in the amplification of the seismic response of the main structure, affecting the safety of the structure.

[0003] In response to the above problems, the patent with publication number: CN113228991A discloses a greenhouse cultivation trough system with shock absorption effect, including a plurality of cultivation troughs, a plurality of first spring units and a plurality of damping units; the plurality of cultivation troughs are suspended on the load-bearing beam of the greenhouse in parallel with each other through a suspension device; each cultivation trough close to the column of the greenhouse is connected to the column through a first spring unit and a damping unit respectively; the swing frequency of the cultivation trough is consistent with the controlled natural vibration frequency of the main structure of the greenhouse; the planting trough is connected to the column of the greenhouse through the first spring and the damping unit to form a tuned mass damper shock-absorbing substructure attached to the main structure of the greenhouse, which can effectively reduce the effect of earthquakes on the main structure of the greenhouse and improve the safety of the main structure of the greenhouse; the planting trough is used as an inertial mass block of the tuned mass damper, and there is no need to design an inertial mass block separately, and it does not occupy excess space in the greenhouse. It can be directly modified based on the existing greenhouse, and the construction is convenient and the shock absorption effect is good.

[0004] However, the greenhouse cultivation trough system with shock absorption function still has the following problems during use: 1. The greenhouse cultivation trough system with shock absorption function has no windproof structure, which can easily cause the greenhouse to shake or even blow up the greenhouse when the wind is strong, and the stability of the greenhouse cannot be maintained in strong winds; 2. Too many dampers need to be installed in the greenhouse cultivation trough system with shock absorption function, and the steel ropes pull the cultivation troughs together, which affects farmers' operations due to too many steel ropes in the greenhouse. Summary of the invention

[0007] In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problem is: A greenhouse cultivation trough system with a shock-absorbing function comprises: a plurality of shed columns and a plurality of shed beams connected to the tops of the shed columns, a plurality of shed frames connected to the tops of the shed beams, a plurality of cultivation frames connected between the plurality of shed beams, and a plurality of cultivation components connected to the bottoms of the cultivation frames; Windproof components are connected between the shed columns at the ends and the corresponding shed frames; Anti-vibration components are connected between two adjacent shed columns.

[0008] Further, the windproof assembly includes: a first connecting rod, a second connecting rod and a first spring; The top of the first connecting rod is connected to the corresponding scaffolding; The bottom of the second connecting rod is connected to the corresponding shed column; The first connecting rod and the second connecting rod are inclined and collinear, and the diameter of the second connecting rod is greater than the diameter of the first connecting rod; The first spring is connected between the first connecting rod and the second connecting rod.

[0009] Furthermore, the first spring cover is provided with a shell, and the top of the shell is slidably sleeved outside the first connecting rod.

[0010] Further, the adjustment assembly includes: a pull ring and a plurality of spring plugs; The pull ring is sleeved on the outside of the first connecting rod; A plurality of notches are arranged on the outer wall of the shell. One end of the spring is connected to the first connecting rod, and the other end extends out of the shell and is clamped at the notch.

[0011] Further, the anti-vibration assembly includes: a gear and two racks; One end of the two racks is connected to the corresponding shed columns respectively; The top and bottom of the gear mesh with two racks respectively.

[0012] Furthermore, two fixing rods are connected between the two shed columns, the two racks are located between the two fixing rods, and a plurality of fourth connecting rods are connected between the fixing rods and adjacent racks; A third connecting rod is connected between any one of the fixed rods and the gear.

[0013] Further, the cultivation assembly includes: a pulley, a bracket and a GTT vibration isolator; The GTT vibration isolator is connected to the bottom of the cultivation rack; The bracket is connected to the bottom of the GTT vibration isolator; The pulley is rotatably connected to the bottom of the bracket The windproof and shock-absorbing method of the present invention comprises the following steps: S1. In windy weather, the windproof component is subjected to oblique upward and downward forces, and the oblique downward force is greater than the oblique upward force; the windproof component is adjusted so that its overall downward force is greater than the upward force exerted by the wind on it, so that its overall force is kept downward to achieve a windproof effect; S2.

[0015] The present invention arranges windproof components on the shed columns at the four corners. After the horizontal forces of the windproof components offset each other, the downward force of each windproof component is greater than the upward force, and the compression degree of the first spring is changed by the spring plug, so that the difference in the force acting on the first connecting rod and the second connecting rod is greater than the upward force of the wind on the windproof component. When the difference in the force is greater than the upward force of the wind on the windproof component, the force acting on the greenhouse as a whole is downward and tends to be stable, and the greenhouse cannot be blown up by strong winds.

[0016] The present invention arranges anti-vibration components so that adjacent shed columns can not only be stabilized by the clamping connection between gears and racks, but also when adjacent shed columns are subjected to left or right forces during an earthquake, the forces are transmitted to the gears through the racks and offset each other as much as possible, thereby ensuring the stability of the greenhouse, avoiding shaking of the cultivation trough, and preventing crops or soil in the cultivation trough from falling due to shaking.

The vibration isolator ensures the stability of the cultivation trough connected by the pulley rope, and does not cause the cultivation trough to shake due to external factors, while preventing the crops or soil in the cultivation trough from falling due to shaking. At the same time, metal rubber vibration isolators are arranged at both ends of each cultivation rack to absorb low-frequency vibrations in earthquakes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example 1

[0022] like Figure 1-9 As shown, the present invention discloses a greenhouse cultivation trough system with a shock-absorbing effect, comprising: a plurality of shed columns 10 and a plurality of shed beams 20 connected to the tops of the shed columns 10, the shed columns 10 and the shed beams 20 form a rectangular structure, such as Figure 5 As shown, a plurality of shelves 30 are connected to the top of the shed beam 20, and the shelves 30 form a triangular structure to improve the overall stability. A plurality of cultivation racks 21 are connected between the plurality of shed beams 20, and the bottom of the cultivation rack 21 can be connected to the cultivation trough to cultivate the plants in the cultivation trough; windproof components are connected between the shed columns 10 located at the four corners of the rectangle and the corresponding shelves 30 to improve the overall stability of the greenhouse and prevent the greenhouse from being blown away in a windy environment; earthquake-proof components are connected between two adjacent shed columns 10, which can effectively reduce the effect of earthquakes on the main structure of the greenhouse and improve the safety of the main structure of the greenhouse.

[0023] Furthermore, if Figure 2-4As shown, the windproof assembly includes: a first connecting rod 60, a second connecting rod 61 and a first spring 65; the first connecting rod 60 is at an angle of 45 degrees to the ground and the top is fixedly connected to the corresponding scaffold 30, the bottom of the second connecting rod 61 is connected to the support rod 67, the support rod 67 is perpendicular to the second connecting rod 61 and is connected to the corresponding scaffold 30; through grooves are provided on the shed beams 20 and shed columns 10 close to the first connecting rod 60 and the second connecting rod 61, and the first connecting rod 60 and the second connecting rod 61 respectively pass through the through grooves on the shed beams 20 and the shed columns 10, and are respectively connected to the scaffold 30 and the support rod 67; the first connecting rod 60 and the second connecting rod 61 are collinear and the diameter of the second connecting rod 61 is larger than the diameter of the first connecting rod 60, and the first connecting rod 60 and the second connecting rod 61 are connected in the middle Spring 65. Since the diameter of the second connecting rod 61 is greater than the diameter of the first connecting rod 60, the strength of the second connecting rod 61 is also greater than the first connecting rod 60, so that the force exerted by the second connecting rod 61 on the first spring 65 is greater than the force exerted by the first connecting rod 60 on the first spring 65. Therefore, the spring force exerted on the second connecting rod 61 is greater than the spring force exerted on the first connecting rod 60. The windproof components are connected to the shed columns 10 at the four corners. After the forces exerted on each windproof structure are decomposed, the horizontal forces of each windproof component offset each other, and the downward force exerted on each windproof component is greater than the upward force. Therefore, when the difference in the forces is greater than the upward force exerted by the wind on the windproof component, the force exerted on the greenhouse as a whole is downward and tends to be stable, and strong winds cannot blow up the greenhouse.

[0024] Furthermore, the first spring 65 is covered with a shell 62, and through holes are provided at the top and bottom of the shell 62. The first connecting rod 60 passes through the top through hole and is slidably sleeved in the shell 62, and the second connecting rod 61 passes through the bottom through hole and is fixedly sleeved in the shell 62; an adjustment component is provided in the shell 62, and the adjustment component is used to adjust the force of the first spring 65 on the first connecting rod 60 and the second connecting rod 61.

[0025] Furthermore, the adjustment component includes: a pull ring 63 and four spring inserts 64, each of which is provided with a second spring 66; the pull ring 63 includes a ring member 631 and four connecting rods connected to the bottom of the ring member 631, and the ring member 631 is fixedly sleeved on the outside of the first connecting rod 60; the shell 62 is rectangular, and a plurality of notches 621 are provided on its front, rear, left and right outer walls, and the notch 621 is a vertical groove and a plurality of transverse grooves perpendicular to the vertical groove, the vertical groove and the transverse groove are connected, and the distances between the plurality of transverse grooves are the same; one end of the four spring inserts 64 are respectively connected to the four connecting rods of the pull ring 63, and the other ends extend to the outside of the front, rear, left and right outer walls of the shell 62 and are clamped at the notches 621; When it is necessary to adjust the force of the first spring 65, the spring insert 64 is moved from the horizontal groove to the vertical groove and adjusted to a high or low position of the horizontal groove to be engaged, thereby achieving different degrees of compression of the first spring 65. When the first spring 65 is compressed to a high degree, its force on the first connecting rod 60 and the second connecting rod 61 is greater, and the overall downward force of the shockproof assembly on the greenhouse shed is increased. By changing the degree of compression of the first spring 65 through the spring insert 64 so that the difference in force on the first connecting rod 60 and the second connecting rod 61 is greater than the upward force of the wind on the windproof assembly, the force on the greenhouse as a whole is downward and tends to be stable, and strong winds cannot blow up the greenhouse.

[0026] Furthermore, if Figure 6 and 7 As shown, the earthquake-proof assembly includes: a gear 52 and two racks 51; one end of the two racks 51 is connected to the corresponding shed columns 10; the top and bottom of the gear 52 are respectively meshed with the two racks 51. During an earthquake, the adjacent shed columns 10 can not only be stabilized by the engagement of the gear 52 and the rack 51, but also when the adjacent shed columns 10 are subjected to a force to the left or right during an earthquake, the force is transmitted to the gear 52 through the rack 51 and offsets each other as much as possible, thereby ensuring the stability of the greenhouse, avoiding shaking of the cultivation trough, and preventing the crops or soil in the cultivation trough from falling due to shaking.

[0027] Furthermore, two fixing rods 50 are connected between the two shelf columns 10, and the fixing rods 50 are respectively located above and below the two racks 51, and a plurality of fourth connecting rods 54 are connected between the fixing rods 50 and the racks 51; two third connecting rods 53 are arranged between the fixing rods 50 and the gear 52, and a rotating shaft 531 is arranged between the two third connecting rods 53, and the gear 52 is rotatably connected to the rotating shaft 531, so as to avoid misalignment of the gear 52 and the rack 51 while improving the stability of the gear 52 and the rack 51. Example 2

[0028] According to Example 1, in order to stably cultivate the plants in the cultivation trough, a cultivation component is further provided, such as Figure 8 and 9As shown, the cultivation assembly includes: a pulley 40, a bracket 41 and a GTT vibration isolator 42; the GTT vibration isolator is connected to the bottom of the cultivation frame 21; the bracket 41 is connected to the bottom of the GTT vibration isolator 42; the pulley 40 is rotatably connected to the bottom of the bracket 41, and the cultivation trough is hung on the pulley 40 through the pulley rope, and the height of the cultivation trough can be adjusted by adjusting the traction line; by arranging a GTT vibration isolator 42 above each cultivation trough, it has excellent performance different from other nonlinear equipment, such as low natural frequency, and good vibration isolation effect on low-frequency and high-frequency interference. This vibration isolator can ensure the stability of the cultivation trough connected by the pulley rope, and the cultivation trough is not shaken by external factors, and at the same time, it can prevent the crops or soil in the cultivation trough from falling due to shaking; metal rubber vibration isolators 211 are arranged at both ends of each cultivation frame 21, and the cultivation frame 21 is connected to the shed beams 20 at both ends through the metal rubber vibration isolators 211, so that the metal rubber vibration isolators 211 absorb low-frequency vibrations in earthquakes.

[0029] Furthermore, in order to prevent the shed columns 10 from shaking as much as possible during an earthquake and provide stability for the greenhouse as a whole, wire rope isolators 70 are arranged at the bottom of the shed columns 10 located at the four corners of the rectangle, which effectively reduce the impact of vibrations such as earthquakes on the greenhouse structure and improve the overall stability and safety of the greenhouse.

[0030] The working principle of the greenhouse cultivation trough system with shock absorption provided in the present invention is: Windproof: Windproof components are connected to the shed columns 10 at the four corners. After the forces of each windproof structure are decomposed, the horizontal forces of each windproof component offset each other, and the downward force of each windproof component is greater than the upward force; the spring plug 64 is adjusted to change the compression degree of the first spring 65 through the spring plug 64, so that the difference in force on the first connecting rod 60 and the second connecting rod 61 is greater than the upward force of the wind on the windproof component. When the difference in force is greater than the upward force of the wind on the windproof component, the force on the greenhouse as a whole is downward and tends to be stable, and the strong wind cannot blow up the greenhouse; Earthquake-proof: adjacent shed columns 10 can not only be stabilized by the clamping connection between the gear 52 and the rack 51, but also when the adjacent shed columns 10 are subjected to a force to the left or right during an earthquake, the force is transmitted to the gear 52 through the rack 51 and offset each other as much as possible, thereby ensuring the stability of the greenhouse and avoiding shaking of the cultivation trough, and preventing the crops or soil in the cultivation trough from falling due to shaking.

It is obvious that those skilled in the art can easily make various modifications to the above embodiments and apply the general principles described herein to other embodiments without creative work.
