Description

Technical Field

[0001] The invention belongs to the technical field of crop planting equipment, and in particular relates to an automatic opening and closing device for a greenhouse. Background Art

[0002] my country is a large agricultural country. Facility agriculture represented by planting equipment is developing rapidly. Among all the areas of facility cultivation, large-scale modern planting equipment has the fastest growth rate. Although the scale and specifications of facilities are constantly improving, there are still some problems that cannot be ignored. The high-tech content of modern planting equipment designed by China is low, and it lacks competitiveness compared with foreign advanced planting equipment. There is no unified technical standard for the structural design and supporting equipment of planting equipment. The internal equipment of planting equipment is relatively simple, and the equipment cannot guarantee favorable conditions for crop growth and cannot meet the needs of crop growth all year round. Many of the introduced planting equipment are not suitable for the climatic conditions of various provinces in my country. my country's East Asian monsoon climate is too different from the coastal areas of temperate countries, so the energy consumption is generally high, mainly due to the high energy consumption of room temperature control, which leads to high operating costs, poor benefits, and unsustainable production.

[0003] The planting device in the prior art includes a planting box, in which crops are planted. Equipment for assisting the planting of crops, such as a humidifier, a heater and the like, is arranged in the planting box. When there is sunlight, the light directly shines on the planting box. In this design, it is impossible to adjust the lighting conditions of the planting box according to the preference of the plants for light. Summary of the invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an automatic opening and closing device for a greenhouse to solve the technical problem that the prior art cannot adjust the lighting conditions. The present invention can adjust the lighting conditions of the planting box according to the growth needs of crops.

[0005] The objective of the present invention is achieved in this way: an automatic opening and closing device for a greenhouse, comprising a planting box, the planting box being connected to an openable and closable shading plate, a plurality of hinges being arranged at the lower portion of the outer side of the planting box, the fixed portion of the hinge being fixedly connected to the outer side of the planting box, the rotating portion of the hinge being fixedly connected to the outer side of the lower portion of the shading plate, and the shading plate being able to cover the south side of the planting box.

[0006] In the present invention, the opening and closing of the sunshade is controlled according to the growth needs of the crops in the planting box. In the initial state, the sunshade is in contact with the south side of the planting box. When the crops need light, the sunshade is opened to the required angle and then stops, allowing sunlight to enter the planting box to provide the crops with suitable light. The present invention can adjust the angle of the sunshade according to actual needs to adapt to the lighting conditions of the crops; it can be applied to light adjustment work during crop planting.

[0007] In order to further realize the opening and closing of the sunshade, it also includes a connecting seat 1 and a connecting seat 2, the connecting seat 1 is rotatably connected with a rotating sleeve 1 and a transmission gear 1, the connecting seat 2 is rotatably connected with a rotating sleeve 2 and a transmission gear 2, a space 1 for accommodating a transmission rack 1 is reserved between the rotating sleeve 1 and the transmission gear 1, and a space 2 for accommodating a transmission rack 2 is reserved between the rotating sleeve 2 and the transmission gear 2. The front side of the sunshade is fixedly connected with a driving motor, and the driving motor is transmission-connected with a rotating shaft, and the left and right ends of the south side of the planting box are respectively fixed with an articulated ear 1 and an articulated ear 2, and a transmission rack 1 is hinged on the articulated ear 1, and the transmission rack 1 extends forward and extends into the space 1, and the two ends of the rotating shaft in the left and right directions are respectively rotatably connected to the support seat 1 and the support seat 2, and the rear side of the transmission rack 1 is meshed with the transmission gear 1, and the front side of the transmission rack 1 is meshed with the transmission gear 1. The side of the transmission rack is in contact with the outside of the rotating sleeve one, and the transmission rack two extends forward and extends into the space two. The rearward side of the transmission rack two is meshed with the transmission gear two, and the front side of the transmission rack two is in contact with the outside of the rotating sleeve two; in this design, in the initial state, the sunshade is in contact with the south side of the planting box. When it is necessary to strengthen the light in the planting box, the driving motor is activated and the rotating shaft is rotated. The rotation of the rotating shaft drives the rotation of the transmission gear one and the transmission gear two. The transmission gear one and the transmission gear two roll along the transmission rack one and the transmission rack two respectively, and the movement direction of the driving motor is controlled so that the transmission gear one and the transmission gear two roll downward along the transmission rack one and the transmission rack two respectively, and the rotating sleeve one and the rotating sleeve two roll along the front side of the transmission rack one and the transmission rack two, and the sunshade swings outward, and sunlight shines into the planting box. When the sunshade is opened to the required angle, the driving motor stops.
