Description

Ladder-type one-span multi-row viticulture rainproof shed

technical field

The utility model relates to the field of modern agricultural cultivation facilities, in particular to a rainproof facility suitable for the cultivation of vines such as grapes. the

Background technique

Whether it is fruit trees or vegetables, they are afraid of rain during some key growth periods, especially during the flowering period and fruit ripening period. Once it rains, the flowers will fall or they will be easily infected with various germs, resulting in various diseases and the fruit will also be damaged. It will rot soon after being infected. For example, if it rains too much during the ripening period, table grapes will significantly change their taste, and wine grapes will greatly reduce the quality of wine. At present, the common greenhouses can play a role in preventing rain, but because the design mainly considers the thermal insulation cultivation in low climate conditions, the lighting and ventilation are poor, which will lead to the lack of sufficient light and ventilation for the grapes. conditions, lead to low yield, poor coloring, affect the appearance and quality, especially in summer rainy and sunny weather, the temperature rises quickly, but it is difficult to discharge the moisture in the canopy in time, and it is easy to form high temperature and high humidity in the greenhouse grapes are prone to various diseases. Due to the unique monsoon climate in our country, the wind will blow when it rains, and the transformation of the traditional rainproof shed into a form that can be opened and closed immediately will inevitably lack wind resistance, and the shed will easily be overturned by wind and rain. the

Grape cultivation is characterized by low tree body, small canopy, and narrow row spacing. As a plant that is harvested once a year, grapes have a relatively limited harvest. It must be comprehensively considered to reduce rain, ventilation, lighting, and safety. Facility costs, therefore, require targeted design of new grape canopies. the

Contents of the invention

The utility model provides a stepped one-span multi-row grape cultivation rain-proof shed, the length of the rain-proof shed depends on the area of the plot or the length of the cultivation row, and the span of the rain-proof shed depends on the row spacing and the number of rows of crops. the

The structure of the stepped one-span multi-row grape cultivation rain-proof shed of the present utility model is an inner pillar overhanging structure system, which consists of a base, a pillar, a web rod, a stepped arch rod, a connecting rod, a laminating line, a slot, Consists of a film roll, film roll shaft, covering material, ridge top venting mechanism, waist step venting mechanism, etc. The base is buried in the ground and mainly bears the pressure of the upper shed body, the uplifting force and shear stress during strong winds. The lower end of the pillar is connected to the base and the upper end is connected to the web to support the gravity of the entire rainproof shed. The length of the web determines The span of the rainproof shed, the top of the stepped arch rod is connected, the lower end is connected with the end of the web rod to form a canopy, which constitutes a stable tripod force system, supports the covering material and divides the rain-proof coverage area into zero, and the connecting rod The two ends are connected with stepped arches, and each tripod is fixed as a whole, so that the whole structure of the shed is stable. The base is a concrete structure, and the pillars, webs, stepped arches and connecting rods are made of metal materials; Pull one at an interval of 1.0m-1.5m, fix the upper and lower ends on the connecting rod, and press the covering material on the skeleton to prevent the covering material from being damaged by fluctuating up and down under the action of the wind. The tightness of the lamination line should be appropriate so that The rolling and unwinding movement of the covering material; the card slot is fixed on the stepped arch bar, and the covering material is fixed in the card slot with a circlip, the film roll shaft is fixed to the lower end of the cover material, and the film roll shaft is provided with roll film at both ends There is an electric or manual control cover material rolling; a ridge top wind release mechanism is provided on the ridge top of the rainproof shed, and a waist stepped wind discharge mechanism is provided on the covering surfaces on both sides of the ridge top. the

The ridge top air release mechanism refers to fixing the covering materials on both sides of the stepped arch bar on the ridge top with card slots respectively, and the covering materials with a certain width are reserved to overlap on the ridge top to form a labyrinth rain-proof leakage mechanism. wind mechanism. The automatic exchange of air is realized by relying on the air pressure difference inside and outside the shed. When the wind needs to be vented, the air in the shed automatically lifts up the plastic film to exhaust; when the internal and external air pressure is balanced, the plastic film hangs down due to gravity and restores its overlapping original shape to prevent rain. the

The waist step air discharge mechanism refers to that the upper and lower layers of non-parallel stepped arch bars are connected to form a trapezoidal air discharge port with relatively vertical homogeneous profiles. Covering material to protect from rain, no covering on the stepped façade. The different slopes of the upper and lower slopes of the air outlet can change the wind inertial flow characteristics under the covering materials at different parts, especially in rainy and windy weather, this structure can generate the largest air discharge at the waist, which can evenly distribute and reduce the covering materials The pressure difference between the upper and lower sides reduces the destructive force of the strong wind on the canopy structure, thus achieving the purpose of wind resistance. The structure can greatly simplify the structural shape and reduce the construction materials. the

The eaves structure of the inner pillar can cover a larger area under the condition of the same pillar, so that the span can be variable and adjustable in a certain range according to different cultivation row spacings. the

The covering material can adopt plastic film, rainproof cloth or non-woven fabric according to different requirements. the

The eaves structure of the inner pillar of the utility model can also adopt a circle or other arc or arch structure, and the ladder can be two-stage or multi-stage ladder structure. the

Beneficial effects brought by the utility model

(1) The utility model adopts the ladder structure of the inner pillar soaring eaves type triangular top frame. In the case of the same pillar, the coverage area of the canopy is increased, the pillar is reduced, the span is adjustable, and the height of the greenhouse is reduced. Ventilation, wind resistance, rain resistance and the effect of reducing construction materials.

(2) A wind release mechanism is installed at the top of the ridge and the steps at the waist, and the coverage area is divided into parts under the premise of ensuring no rain leakage. Strong, fully able to withstand the test of strong winds and heavy rains in the north. the

(3) There is an electric or manual covering material unwinding mechanism on the top, which is conducive to rain protection, lighting and ventilation. When it rains, put down the covering material to prevent rain, and roll up the covering material when there is no rain, which will not affect the lighting at all, and will not affect the natural growth conditions of grapes. It can improve the utilization rate of cultivated land, and is conducive to intensive, large-scale, high-quality grape production. the

(4) The utility model is suitable for the full coverage of 4-6 rows of grapes, and is also suitable for the windproof and rainproof cultivation of other vines and vegetables. the
