Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural engineering, in particular to a multi-dimensional temperature adjustment continuous ridge greenhouse. BACKGROUND

[0002] Greenhouses are widely used in the field of agriculture. Greenhouses not only provide shelter from wind and rain, but also allow for artificial control of temperature and humidity, reducing the occurrence of diseases and pests. In addition, greenhouses can also advance or delay the harvesting period of crops, allowing for off-season cultivation of crops, thereby improving planting efficiency and extending the supply time of crops to meet the material needs of the people. Among them, continuous ridge greenhouses are widely used by agricultural planting personnel due to their advantages of saving space, saving cost, and good stability.

[0003] The existing continuous ridge greenhouse structure mainly includes a framework, and a greenhouse film made of a flow-dripping membrane material is arranged on the framework from the outside to the inside, followed by an inner heat preservation film made of a flow-dripping membrane material. An ordinary black sunshade net is also arranged on the framework, and ventilation in the greenhouse is achieved by opening ventilation openings on the sides and top of the greenhouse and installing a fan.

[0004] However, for special regions with extreme climates, such as the Yangtze River Delta region, where the temperature drops below -7 degrees Celsius in winter and the outside temperature reaches above 42 degrees Celsius in summer, the above-mentioned greenhouse has certain heat preservation effect in winter, but it is not obvious. In the summer, when the windows of the greenhouse are fully opened and the sunshade net is fully deployed, the ordinary sunshade net will absorb light and cause the material to heat up, which will result in the temperature inside the greenhouse being higher than the outside temperature. The ventilation function formed by the fan and the ventilation opening is unidirectional, and cannot meet the requirements of ventilation and cooling inside the greenhouse, making it difficult for crops to grow in the greenhouse.

[0074] Embodiment 2:

[0075] With reference to Figure 11 The difference between the embodiment and embodiment 1 is that the third winding device 9 can also be composed of a driving gear 95, a driven gear 96, a driving member 97, a synchronous tooth belt 98 and a clamping assembly 99. The driving gear 95 and the driven gear 96 are both rotatable on the framework 1, and the driving gear 95 and the driven gear 96 are respectively located at one end of the framework 1 in the width direction. The synchronous tooth belt 98 is wound on the driving gear 95 and the driven gear 96, and the synchronous tooth belt 98 is engaged with the driving gear 95 and the driven gear 96. The driving member 97 is used to drive the driving gear 95 to rotate. In this embodiment, the driving member 97 is preferably a servo motor 400. The output shaft of the servo motor 400 is coaxially fixedly connected with the driving gear 95. The servo motor 400 is fixed on the framework 1 by bolts.

[0076] With reference to Figure 11 and Figure 12 The clamping assembly 99 is arranged on the sliding frame 62. The clamping assembly 99 is used to clamp the sliding frame 62 and one side of the synchronous tooth belt 98 together. The clamping assembly 99 comprises a bottom plate 991 fixed on the sliding frame 62, a first side plate 992 and a second side plate 993 arranged at both ends of the bottom plate 991, a third side plate 994 and a fourth side plate 995 sliding on the bottom plate 991, a bidirectional pneumatic cylinder 996 mounted on the bottom plate 991, and an insert block 997 fixed on the piston rod end of the bidirectional pneumatic cylinder 996. The third side plate 994 is located on the same side as the first side plate 992, and the fourth side plate 995 is located on the other side as the second side plate 993. Reset springs 998 are arranged between the third side plate 994 and the first side plate 992 and between the second side plate 993 and the fourth side plate 995.

[0077] With reference to Figure 11 and Figure 12 The reset spring 998 between the third side plate 994 and the first side plate 992 is abutted on the first side plate 992 at one end and on the third side plate 994 at the other end. The reset spring 998 between the second side plate 993 and the fourth side plate 995 is abutted on the second side plate 993 at one end and on the fourth side plate 995 at the other end. The bidirectional pneumatic cylinder 996 is located between the synchronous tooth belt 98. When the piston rod of the bidirectional pneumatic cylinder 996 is extended, the insert block 997 can be inserted into the tooth groove between the adjacent two teeth of the synchronous tooth belt 98, so as to realize the clamping of the synchronous tooth belt 98 through the cooperation of the insert block 997 and the corresponding third side plate 994 or fourth side plate 995. In order to avoid the influence of the third side plate 994 or the fourth side plate 995 on the rotation of the synchronous tooth belt 98, the third side plate 994 and the fourth side plate 995 are made of plastic material with small surface friction coefficient in this embodiment.

[0078] With reference to Figure 11 and Figure 12, when in use, the third side plate 994 and the fourth side plate 995 slide relative to each other under the elastic force of the two reset springs 998, and abut against the side wall of the synchronous tooth belt 98, so as to ensure the tension of the synchronous tooth belt 98; when the piston rod of one side of the bidirectional air cylinder 996 extends, the plug 997 is inserted into the tooth slot between two adjacent teeth of the synchronous tooth belt 98, so as to drive the clamping assembly 99 to slide as a whole under the driving of the synchronous tooth belt 98 and the cooperation between the plug 997 and the teeth, and then drive the sliding frame 62 to slide, so as to realize the unfolding or rolling of the first area net 61; in order to ensure that the plug 997 can be inserted into the tooth slot of the synchronous tooth belt 98, a guide inclined surface is arranged at the end of the plug 997, and the guide inclined surface cooperates with the inclined surface of the teeth of the synchronous tooth belt 98.

[0079] With reference to Figure 11 and Figure 12 In addition, during the rotation of the synchronous tooth belt 98, the driving directions of the two sides of the synchronous tooth belt 98 are opposite, so when the piston rods of the two sides of the bidirectional air cylinder 996 are in the retracted state, the sliding frame 62 connected with the bidirectional air cylinder 996 at this position is stationary during the rotation of the synchronous tooth belt 98, which is the first working state; when the piston rod of one side of the bidirectional air cylinder 996 extends, the plug 997 is inserted into the tooth slot of the synchronous tooth belt 98, and during the rotation of the synchronous tooth belt 98, the plug 997, the teeth and the third side plate 994 cooperate to drive the sliding frame 62 connected with the bidirectional air cylinder 996 at this position to slide forward, so as to realize the unfolding of the corresponding first area net 61, which is the second working state; when the piston rod of the other side of the bidirectional air cylinder 996 extends, the corresponding plug 997 is inserted into the tooth slot on the other side of the synchronous tooth belt 98, and during the rotation of the synchronous tooth belt 98, the plug 997, the teeth and the fourth side plate 995 cooperate to drive the sliding frame 62 connected with the bidirectional air cylinder 996 at this position to slide reversely, so as to realize the rolling of the corresponding first area net 61.

[0080] The implementation principle of the embodiment is that: in actual application, the first working state, the second working state and the third working state can be used in cooperation to realize the synchronous unfolding or rolling of all the first area nets 61, or the synchronous unfolding or rolling of some of the first area nets 61 while the others remain stationary, or the forward unfolding of one or several first area nets 61 while the reverse rolling of the others, so as to improve the overall applicability of the device, enable the staff to adjust the light area according to the growth habits of the crops in different planting areas of the greenhouse, facilitate the crops in different areas to carry out photosynthesis, and thus provide a growth environment suitable for different types of crops in the greenhouse.
