Description
Technical Field
The utility model belongs to the technical field of the greenhouse technique and specifically relates to a novel film mechanism is rolled up to canopy in lian dong greenhouse is related to.
Background
The membrane rolling and ventilating mechanism of the inner shed roof of the multi-span greenhouse for agricultural planting production generally adopts two forms of manual membrane rolling and ventilating and electric membrane rolling and ventilating, wherein a component for supporting a membrane rolling motor in the electric membrane rolling and ventilating mechanism is a telescopic sleeve component, and the manual membrane rolling and ventilating mechanism is operated by adopting a lengthened membrane rolling handle.
Under the condition that a growing frame or an internal heat preservation/sun-shading system is arranged in the multi-span greenhouse, due to structural limitation, only local ventilation can be formed in the width direction of the roof of the internal greenhouse, the ventilation range cannot be expanded to the range of the whole roof, and the ventilation and dehumidification capabilities of the greenhouse are limited.
As a very effective thermal insulation device under cold conditions, a multi-span greenhouse internal shed system is playing an increasingly important role in the development process of high-efficiency agriculture. According to the industrial experience, the east heating composition of the multi-span greenhouse provided with the internal greenhouse system can be reduced by 25-30%. The roof of the internal shed system is usually covered by a plastic film, and in order to enhance the heat preservation effect, the sealing performance of the covering system is mainly concerned when the internal shed system is built.
A ventilation system for opening windows on the roof of a greenhouse is a necessary auxiliary device for planting the greenhouse, and can exhaust harmful gases in the greenhouse, supplement carbon dioxide necessary for the growth of crops and exhaust accumulated water vapor in the greenhouse by establishing an effective exchange way for ventilation between the inside and the outside of the greenhouse and air, thereby creating good growth conditions for the plants. The larger the roof opening area is, the better the ventilation/dehumidification effect of the greenhouse is, and therefore, the roof opening area is a key index for inspecting the performance of the window-opening ventilation system.
As a second layer of covering material in the greenhouse, the inner shed roof also needs to be opened for ventilation, the common ventilation device is a roller shutter ventilation device, and a driving mechanism of the roller shutter ventilation device is divided into two structures of an electric film rolling device and a manual film rolling device.
The growth frame and the internal heat preservation/sun shading system are also necessary auxiliary devices for most agricultural planting multi-span greenhouses, the growth frame is used for hanging crops or vines thereof, and the internal heat preservation/sun shading system is used for regulating and controlling light and temperature environment parameters of the greenhouses; both structurally require longitudinal tensioning members (growing frame steel wires or heat preservation/sunshade support curtain lines) to be arranged in the greenhouse along the gutter direction of the greenhouse, and the two ends of the tensioning members are connected to special beams positioned on the mountain wall surfaces at the two ends of the greenhouse.
As shown in fig. 1, the normal working state of the electric film rolling device with the existing structure comprises an upright post 1, a gutter 2, a water balance beam 5, a growing frame end beam 6, a growing frame steel wire 7, an outer shed arch bar 3 and an inner shed arch bar 4 which form a main frame of a greenhouse, and the electric film rolling device comprises an electric film rolling device 9, a telescopic swing rod assembly 10, a fixed hinge 13, a film rolling rod, a film pressing card and the like. The upper end of the inner shed roof covering material (plastic film) is fixed on the clamping groove 8 at the top end of the inner shed arch bar 4, and the other end (lower end) is fixed on a film rolling rod which is coaxial with the output shaft of the electric film rolling device 9 through a film pressing clamp; the electric film winder 9 drives the film winding rod to rotate, and the window covering material is wound on the film winding rod; the film rolling rod is pulled by the residual window film to move from the lower right initial position to the upper left along the upper surface of the inner shed arch rod 4.
The telescopic sleeve pipe assembly 10 is used for inhibiting the rotation trend of the electric film rolling device 9 around an output shaft of the electric film rolling device in the working process, and ensures that the electric film rolling device can move along the upper surface of the inner shed arch bar 3 along with the film rolling bar. The assembly consists of a rigid outer sleeve 11 and an inner sleeve rod 12, wherein the outer sleeve 11 is a pipe and the inner wall is smooth; the inner sleeve rod 12 can be a pipe or a bar, has a smooth outer section, and can freely slide in the outer sleeve 11 along the axial direction of the outer sleeve 11. One end of one of the sleeve component units (can be an outer sleeve 11 or an inner sleeve rod 12) is rigidly connected with the electric film rolling device 9 through a mounting hole at the tail part of the film rolling device, the far end of the other component unit is fixed on a cross beam 6 at the end of the growing rack positioned on the inner side of the vertical surface of the greenhouse end through a fixed hinge, and the whole component can rotate around the hinge axis in a vertical plane. In order to ensure the normal operation of the assembly itself, the telescopic tube assembly 10 needs to ensure the minimum nesting amount (N, as shown in fig. 1) between the outer tube 11 and the inner rod 12, otherwise the assembly may be subjected to telescopic clamping phenomenon, which may finally lead to the disassembly of the assembly structure (as shown in fig. 2).
The nesting length of the telescopic sleeve pipe assembly 10 is increased continuously as the electric film rolling device 9 moves from the lower right corner to the upper left corner; when the electric film rolling device 9 moves to the position where the axis of the telescopic sleeve is vertical to the longitudinal direction of the inner shed arch bar 3, the nesting length of the telescopic sleeve reaches the maximum value; the motorized film winder 9 continues to move up and to the left and the telescoping tube viewing sleeve length continues to decrease until the nested length decreases to the limit (as shown in figure 1).
As can be seen from fig. 1 and 2, the maximum inner roof window opening width (Wmax) of the electric film rolling device of the prior art cannot reach the inner roof window opening width (W0) due to the structural form, the installation position of the fixed hinge point and the length of the telescopic tube assembly 10.
As shown in fig. 3, the normal working state of the manual film rolling device with the existing structure comprises a vertical column 1, a gutter 2, a water balance beam 5, a growing frame end beam 6, a growing frame steel wire 7, an outer shed arch bar 3 and an inner shed arch bar 4 which form a main frame of a greenhouse, and the device comprises a manual film rolling device 9 (a turbine worm reducer), a lengthened film rolling handle 14, a film rolling bar, a film pressing card and the like. Similar to the electric film rolling mechanism, the upper end of the inner shed roof covering material (plastic film) is also fixed on the clamping groove at the top end of the inner shed arch bar 4, and the other end (lower end) is fixed on the film rolling bar which is coaxial with the output shaft of the manual film rolling device through a film pressing clamp; an operator rotates the lengthened film winding handle, the manual film winding device drives the film winding rod to rotate, and the window covering material is wound on the film winding rod; the film rolling rod is pulled by the residual window film to move from the lower right initial position to the upper left along the upper surface of the inner shed arch rod.
Although the operator can move in the width direction of the greenhouse to expand the window-opening width of the inner roof in the process of operating the manual film rolling device, the maximum window-opening width (Wmax) of the inner roof in the manual film rolling mode is still far less than the window-opening width of the inner roof (as shown in fig. 3) under the influence of the arrangement interval of the steel wires of the growing frames (the distance between the adjacent steel wires is usually 0.5m) and the manual operable range (height).
