Description

Technical Field

[0001] The utility model relates to a greenhouse, in particular to a sunshade system of the greenhouse. Background Art

[0002] Greenhouses are often used for growing vegetables and raising green plants and flowers, providing a suitable temperature environment for their growth. In winter, charcoal burning, heating and other methods are generally used to increase the temperature in the greenhouse. In summer, a sunshade system is generally used to reduce light to lower the temperature in the greenhouse. The current sunshade system is generally a sunshade net. An electric roller for rolling up the sunshade net is rotatably set on the frame of the greenhouse. A connecting strip is fixed on the edge of the sunshade net, and the connecting strip slides horizontally on the frame of the greenhouse. That is, the sunshade net is released, and then the connecting strip is moved to drive the sunshade net to unfold for shading. The current sunshade system still has problems: it is fully opened or closed when in use, and there are few ways to use it; it is inconvenient to operate, disassemble and repair.

[0026] See also Figure 1 and Figure 2 A sunshade system for a greenhouse includes a plurality of sunshade groups 1, a second mounting part 2, a motor 3 and a rack 4.

[0027] Each sunshade group 1 includes a mounting strip 1a, a push rod 1b and a sunshade net 1c.

[0028] The mounting strip 1a is used to be fixedly connected to the frame of the greenhouse, thereby mounting the sunshade group 1 to the greenhouse.

[0029] The push rod 1b is horizontally slidably connected to the mounting bar 1a, and the direction in which the push rod 1b slides back and forth is set as a first direction.

[0030] See also Figure 1 and Figure 4 Optionally, the push rod 1b can be slidable in a manner that an upper limit wheel 1a2 and a lower limit wheel 1a3 are rotatably provided on the mounting bar 1a for the push rod 1b to slide, and the upper limit wheel 1a2 and the lower limit wheel 1a3 are located at the upper side and the lower side of the push rod 1b, respectively. Specifically, a first mounting portion 1a1 for connecting the upper limit wheel 1a2 and the lower limit wheel 1a3 is fixedly provided on the bottom surface of the mounting bar 1a, and both the upper limit wheel 1a2 and the lower limit wheel 1a3 have a first annular groove that fits into the outer wall of the push rod 1b.

[0031] The sunshade net 1c is arranged on the mounting strip 1a, and can be unfolded and folded along the first direction. Specifically, the mounting strip 1a can be hollow with an inner cavity, and a groove connecting the inner cavity is arranged on the outer wall on one side. A roller for winding up the sunshade net 1c is rotatably arranged in the inner cavity of the mounting strip 1a, and the sunshade net 1c extends out through the groove. The edge of the sunshade net 1c away from the mounting strip 1a is connected to the push rod 1b, and specifically, a connecting rod 1b2 can be arranged between the two. The push rods 1b in all the sunshade groups 1 are fixedly connected head to tail, so that by moving the push rod 1b, all the sunshade nets 1c can be unfolded together. In addition, a clockwork spring sheet can be arranged between the roller and the mounting strip 1a. When the sunshade net 1c is extended, it needs to overcome the clockwork spring sheet, and accordingly, the push rod 1b is moved in the opposite direction, and all the sunshade nets 1c are folded together under the action of the clockwork spring sheet.

[0032] See also Figure 1 and Figure 4 , the second mounting part 2 is fixedly connected to one of the mounting strips 1a, and a gear 2a is rotatably provided. A first mounting part 1a1 for connecting the upper limit wheel 1a2 and the lower limit wheel 1a3 is fixedly provided on the bottom surface of the mounting strip 1a, that is, for the mounting strip 1a, the first mounting part 1a1 may not be provided, and the upper limit wheel 1a2, the lower limit wheel 1a3 and the gear 2a are provided together on the second mounting part 2. Specifically, the upper limit wheel 1a2 and the gear 2a are located directly below the mounting strip 1a, and the lower limit wheel 1a3 exceeds the mounting strip 1a.

[0033] Accordingly, the first mounting portion 1a1 may not exceed the mounting strip 1a. During the movement of the push rod 1b, the mounting position of the push rod 1b on the connecting rod 1b2 and the connecting position between the two push rods 1b will not intersect with the upper limit wheel 1a2 and the lower limit wheel 1a3, thereby not causing interference. Compared with the first mounting portion 1a1, the second mounting portion 2 has a larger size in the first direction, and a portion of it will exceed the mounting strip 1a for the lower limit wheel 1a3 to be set. During the movement of the push rod 1b, the mounting position of the push rod 1b on the connecting rod 1b2 and the connecting position between the two push rods 1b will pass the lower limit wheel 1a3, thereby possibly causing interference.

[0034] See also Figure 5 Optionally, the sunshade net 1c and the push rod 1b can be connected in the following manner: a second annular groove 1b1 is provided on the push rod 1b, a connecting rod 1b2 is fixedly provided on the edge of the sunshade net 1c away from the mounting strip 1a, and a clamp 1b3 that matches the second annular groove 1b1 is fixedly provided at the lower end of the connecting rod 1b2. That is, for the clamp 1b3, only the part of the top of the clamp 1b3 that is used to connect with the connecting piece exceeds the second annular groove 1b1. With such a connection method, during the movement of the push rod 1b, the clamp 1b3 and the connecting rod 1b2 will not interfere with the lower limit wheel 1a3.

[0035] See also Figure 3 and Figure 5 Optionally, the connection between the two push rods 1b can be: a first groove 1b4 is provided at one end of the push rod 1b, and a second groove 1b5 is provided at the other end; a connecting block 1b6 and a hand bolt 1b7 are provided between the adjacent first groove 1b4 and the second groove 1b5. Specifically, the hand bolt 1b7 is threadedly connected to the connecting block 1b6. When connecting two adjacent push rods 1b, the hand bolt 1b7 is first rotated, and the distance between the nut and the connecting block 1b6 is appropriately increased; then the connecting block 1b6 and the hand bolt 1b7 are placed together in the adjacent first groove 1b4 and the second groove 1b5, and finally the hand bolt 1b7 is tightened. With such a connection method, during the movement of the push rod 1b, the connection position between the two push rods 1b will not interfere with the lower limit wheel 1a3, and it is also convenient for the disassembly between the two push rods 1b.

[0036] The motor 3 is used to drive the gear 2a to rotate. Specifically, the motor 3 can cooperate with a reducer 3a, the reducer 3a is fixedly connected to the corresponding mounting bar 1a, the motor 3 is installed at the input end of the reducer 3a, and the output shaft of the reducer 3a is fixedly connected to the gear 2a.

[0037] The rack 4 is arranged on one of the push rods 1b and meshes with the gear 2a, that is, through the gear 2a and the rack 4, the motor 3 can drive all the push rods 1b to move back and forth together.

[0038] Optionally, the bottom surface of the push rod 1b is provided with a plurality of notches to form the above-mentioned rack 4.
