Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to an adjustable arch shed structure for agriculture. Background Technique

[0002] The arch shed for agriculture, also known as an arched greenhouse, is a protective facility with a curved structure, mainly used for growing various crops such as vegetables and flowers. It is usually made of metal, wood or PVC pipes as supports, and the outside is covered with transparent plastic films, polycarbonate plates or glass to allow sunlight to pass through to the maximum extent while maintaining the temperature and humidity inside the shed. The design of the arch shed can effectively capture sunlight and create a warm growing environment, thereby extending the growing season of crops and increasing yields; at the same time, it can protect against adverse climate factors such as rain, wind and frost, reduce the invasion of pests and diseases, and reduce the use of chemical pesticides. During use, it is necessary to pay attention to maintaining proper ventilation to prevent high temperature or high humidity from affecting crops; reasonable irrigation management is also crucial to prevent root rot. The arch shed plays an important role in modern agriculture and has become an effective tool for improving the yield and quality of agricultural crops.

[0003] The specification of the Chinese utility model patent CN215188499U discloses a ventilation adjustment device for arch shed quilts, including a keel frame; an adjustment device arranged on the keel frame; wherein, the keel frame includes symmetrically arranged mounting frames and support beams arranged evenly between the mounting frames; and the support beams pass through the mounting frames; an installation plate is arranged at the end of the support beam in the middle of the mounting frame, and the adjustment device is arranged on the installation plate; the adjustment device includes a driving roller and a driving device for driving the driving roller to rotate; a transmission belt is sleeved on the two driving rollers, and the transmission speed of the transmission belt is the same as the linear speed of the driving roller; the axis of the driving roller is horizontally arranged. Beneficial effects: Pull the connecting rope, and the two ends of the connecting rope are pulled in one direction and the other in the opposite direction to achieve the effect of tying the quilts. As the transmission belt moves, the quilts are tied tightly, and the gap between the quilts is large, so the light-transmitting and air-permeable openings of the greenhouse are large, and the purpose of quickly adjusting the size of the light-transmitting and air-permeable holes according to needs is realized.

[0004] In the above patent, the greenhouse still needs to be adjusted manually, and the external weather may change in real time. Once the temperature inside the greenhouse is too high or the humidity is too high and ventilation is not timely, it will affect the growth of crops. Therefore, the applicant proposes an adjustable arch shed structure for agriculture. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable arch shed structure for agriculture to solve the problem of manual adjustment of ventilation of the greenhouse proposed in the above background technique.

[0026] The following will combine the attached Figures 1 to 5 The present utility model will be described in detail. The technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides an agriculturally convenient adjustable arch shed structure through improvement, such as Figure 1 - Figure 5As shown in the figure, it includes an arch shed frame assembly 1. The arch shed frame assembly 1 includes a plurality of arched frames 101. At the lower ends of the plurality of arched frames 101, insertion rods 102 are fixedly connected. At the upper ends of the plurality of arched frames 101, a same fixed cylinder 103 is fixedly connected. Inside the fixed cylinder 103, a rotating shaft 104 is rotatably connected. At one end of the fixed cylinder 103, a motor 105 is fixedly connected. The structure and principle of the motor 105 are both prior arts and will not be elaborated here. And the output end of the motor 105 is fixedly connected to the rotating shaft 104. An air monitor 106 is installed on the arched frame 101. The air monitor 106 can monitor the temperature and humidity of the air inside the arch shed. When the air temperature and humidity exceed the set values, the motor 105 can be controlled to start by the controller. The value ranges of the air temperature and humidity can be set according to actual needs. And the air monitor 106 is electrically connected to the motor 105. On the left and right side walls of the plurality of arched frames 101, a same winding assembly 3 is fixedly connected. Between the winding assembly 3 and the rotating shaft 104, an arch shed cloth assembly 2 is fixedly connected. Below the winding assembly 3, a ventilation assembly 4 is provided;

[0028] The winding assembly 3 includes a winding cylinder 301. Between the inner walls at both ends of the winding cylinder 301, a winding shaft 302 is rotatably connected. Between the winding shaft 302 and the winding cylinder 301, a torsion spring 303 is fixedly connected. The arch shed cloth assembly 2 includes a plurality of connecting ropes 201 fixedly connected to the rotating shaft 104. The plurality of connecting ropes 201 are fixedly connected to a same shed cloth 202. And the shed cloth 202 is wound around the winding shaft 302.

[0029] In this embodiment: When it is necessary to wind or unfold the arch shed cloth assembly 2, the motor 105 can be started. The motor 105 drives the rotating shaft 104 to rotate, winds the connecting ropes 201, and the connecting ropes 201 can pull the shed cloth 202 upward until the connecting ropes 201 are completely wound into the fixed cylinder 103. The shed cloth 202 will pull the winding shaft 302 to rotate, making the winding shaft 302 in a unwinding state. At this time, the arch shed is completely in a closed state. When the motor 105 rotates in reverse, the connecting ropes 201 are unwound. The winding shaft 302 rotates under the action of the torsion spring 303, and winds the shed cloth 202 into the winding cylinder 301. At this time, the arch shed is completely in an open state. The open state is as shown in Figure 5 the figure;

[0030] When the arch shed is completely in a closed state, resulting in the air temperature and humidity inside it exceeding the set values, the motor 105 is controlled by the controller to start and the rotating shaft 104 rotates in reverse for a certain number of turns, so that the rotating shaft 104 unwinds a certain length of the connecting ropes 201. At this time, the arch shed is in a semi-closed state, which can improve the air permeability of the arch shed, facilitate the cooling of the air inside the arch shed and the discharge of water molecules, and reduce the air humidity.

[0031] In the above embodiments, in order to further improve the ventilation effect after the air temperature or humidity inside the arch shed, the following methods can be adopted for implementation:

[0032] In a preferred embodiment, the ventilation assembly 4 includes a ventilation box 401 fixedly connected to the lower end of the winding drum 301. The ventilation box 401 is fixedly connected with a fixing plate 402. The upper side wall of the fixing plate 402 is fixedly connected with a cylinder 403. A magnetic plug 404 is slidably connected inside the cylinder 403. A return spring 405 is fixedly connected between the magnetic plug 404 and the cylinder 403. A magnet bar 406 magnetically attracted to the magnetic plug 404 is fixedly connected to the winding shaft 302. Two rotating cylinders 407 are rotatably connected to the ventilation box 401. A connecting shaft 408 is fixedly connected between the two rotating cylinders 407. A pulling rope 409 is fixedly connected between the magnetic plug 404 and the connecting shaft 408, and the pulling rope 409 is wound around the connecting shaft 408.

[0033] It should be noted that only after the motor 105 reverses and stops upon receiving the ventilation instruction, the number of reverse rotations is controlled by the motor 105 so that the magnet bar 406 fixedly connected to the winding shaft 302 can be exactly above the magnetic plug 404. When the arch shed cloth assembly 2 is in a fully wound or fully unfolded state, when the winding shaft 302 rotates to the end, the magnet bar 406 is not on the upper side of the magnetic plug 404, so there will be no magnetic attraction with the magnetic plug 404. In addition, since a small-diameter hole is drilled at the upper end of the cylinder 403, the magnetic plug 404 can only move upward slowly, and when the winding shaft 302 rotates normally, it cannot drive the magnetic plug 404 to move upward.

[0034] In this embodiment, after the rotating shaft 104 reverses a certain number of turns, the winding shaft 302 rotates a certain number of turns under the elastic force of the torsion spring 303, so that the magnet bar 406 fixedly connected to the winding shaft 302 can be exactly above the magnetic plug 404, thereby attracting the fixing plate 402 to move upward slowly. Furthermore, the connecting shaft 408 is pulled by the pulling rope 409 to rotate 90 degrees, and the connecting shaft 408 drives the rotating cylinder 407 to rotate 90 degrees, so that the inside of the arch shed communicates with the outside through the holes of the rotating cylinder 407, achieving a further ventilation effect.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
