Description

Technical Field

[0001] The utility model relates to the technical field of vegetable greenhouses, in particular to a temperature-adjustable vegetable greenhouse. Background Art

[0002] Existing vegetable greenhouses use built-in temperature sensors to monitor the temperature inside the greenhouse. When the temperature is too high, the "door curtains" at both ends of the greenhouse are manually opened, or the edges of the greenhouse are flipped upwards. This manual operation is not only time-consuming and labor-intensive; this cooling method will cause the temperature in the greenhouse to be uneven (especially the method of opening the "door curtains" at both ends of the greenhouse, which will cause the temperature at both ends of the greenhouse to drop faster, while the temperature near the center of the greenhouse will drop slower).

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0023] The utility model provides a vegetable greenhouse with adjustable temperature. Figure 1-4 , including a greenhouse body 1, the greenhouse body 1 is covered with a plastic film 2, both ends of the greenhouse body 1 are equipped with winding mechanisms, the two ends of the plastic film 2 are respectively wound on the two winding mechanisms, and the plastic film 2 is provided with rows of holes at intervals.

[0024] The two winding mechanisms are respectively configured as a first winding mechanism located on the left side of the greenhouse body 1 and a second winding mechanism located on the right side of the greenhouse body 1. The structures of the first winding mechanism and the second winding mechanism are exactly the same; and the two first winding mechanisms and the second winding mechanisms cooperate with each other, one of which winds up the plastic film 2, and the other releases the plastic film 2.

[0025] The first winding mechanism comprises a first support frame 102 , to which a first winding roller 106 is rotatably connected via a bearing, and the first winding roller 106 is transmission-connected to a first servo motor 103 .

[0026] The first servo motor 103 is mounted on the first support frame 102 , and a first driving pulley 104 is fixedly mounted on the output shaft of the first servo motor 103 . The first driving pulley 104 is connected to the first driven pulley 107 through a first belt 105 , and the first driven pulley 107 is fixedly mounted on the first winding roller 106 .

[0027] The bottom end of the first support frame 102 is fixedly connected to the first support plate 101, the first support plate 101 is welded to the greenhouse body 1, and the greenhouse body 1 is welded with a first guide wheel 109 that is transmitted to the plastic film 2. The first guide wheel 109 is rotatably connected to the first bracket 110 through a bearing. The first bracket 110 is welded to the greenhouse body 1, and the plastic film 2 is guided by the first guide wheel 109 so that the plastic film 2 can stick to the greenhouse body 1.

[0028] The second winding mechanism comprises a second support frame 202 , to which a second winding roller 206 is rotatably connected via a bearing, and the second winding roller 206 is transmission-connected to a second servo motor 203 .

[0029] The second servo motor 203 is mounted on the second support frame 202 , and a second driving pulley 204 is fixedly mounted on the output shaft of the second servo motor 203 . The second driving pulley 204 is connected to the second driven pulley 207 through a second belt 205 , and the second driven pulley 207 is fixedly mounted on the second winding roller 206 .

[0030] The bottom end of the second support frame 202 is fixedly connected to the second support plate 201, the second support plate 201 is welded to the greenhouse body 1, and the greenhouse body 1 is welded with a second guide wheel 209 that is transmitted to the plastic film 2. The second guide wheel 209 is rotatably connected to the second bracket 210 through a bearing. The second bracket 210 is welded to the greenhouse body 1, and the second guide wheel 209 is used to guide the plastic film 2 so that the plastic film 2 can stick to the greenhouse body 1.

[0031] The plastic film 2 is provided with rows of holes at intervals, so that the plastic film 2 forms a breathable section 21 and a sealing section 22. The lengths of the breathable section 21 and the sealing section 22 are sufficient to cover the greenhouse body 1. When the breathable section 21 covers the greenhouse body 1, the rows of holes on the breathable section 21 can be used to dissipate heat; when the sealing section 22 covers the greenhouse body 1, the greenhouse can be sealed.

[0032] A temperature sensor, a heating tube and a controller are installed in the greenhouse. The controller is used to control the start and stop of the first servo motor 103 and the second servo motor 203, as well as the on and off of the power supply of the heating tube. When the temperature is low, the power supply of the heating tube is turned on to heat the inside of the greenhouse.

[0033] During specific use, the temperature sensor monitors the temperature in the greenhouse. When the temperature rises, the controller controls the first servo motor 103 and the second servo motor 203 to rotate in the same direction, driving one end of the plastic film 2 to be rolled up and the other end to be released, thereby covering the air permeable section 21 on the greenhouse body 1, and using the through holes of the air permeable section 21 for heat dissipation; by the same token, the first servo motor 103 and the second servo motor 203 rotate in opposite directions, so that the sealing section 22 can be covered on the greenhouse body 1. Example 2

[0034] See attached Figure 5 , which is different from Example 1, is that at this time, the plastic film 2 is alternately provided with air-permeable sections 21 and sealing sections 22; thus, even if one of the air-permeable sections 21 or the sealing sections 22 is damaged, the other air-permeable sections 21 or the sealing sections 22 can still be used to perform the corresponding work.

[0035] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
