Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a windproof device for a greenhouse insulation blanket. Background Technology

[0002] After being lowered at night, the insulation blankets in solar greenhouses are laid flat on the greenhouse surface. Because the blankets are lightweight and have a large surface area, the large air pressure difference between the top and bottom of the blankets during windy weather causes them to be frequently blown up, damaging the rolling shutter mechanism. Currently, most greenhouse blankets do not have windproof devices installed. Some have windproof cables, but these locks require manual tightening after the shutter is closed and manual loosening when the shutter needs to be opened, failing to provide automatic windproofing.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figures 1-4 The present invention will be further described in detail below with reference to specific embodiments.

[0020] This embodiment uses a windproof device for a greenhouse insulation blanket, which can automatically lock and release the insulation blanket roll rod. It includes a gear box locking mechanism 2, a steel pipe telescopic mechanism 3, a connecting rod structure 4, and a ground anchor plate 1-3. The gear box locking mechanism 2 is composed of a gear box 2-1 and a semi-circular inner gear ring 2-2. The semi-circular inner gear ring 2-2 is embedded in the semi-circular slide rail of the gear box 2-1. The gear box 2-1 is connected to the thick sleeve 3-1 by bolts.

[0021] The steel pipe telescopic mechanism 3 consists of a coarse sleeve 3-1, a spring 3-2, and a fine sleeve 3-3. The spring 3-2 is inside the fine sleeve 3-3 and the coarse sleeve 3-1, and one end of the fine sleeve 3-3 is inside the coarse sleeve 3-1. The connecting rod structure 4 consists of a bolt rod 4-1 and a threaded tube 4-2. One end of the threaded tube 4-2 is provided with an internal thread that matches the thread of the bolt rod 4-1. The total length of the connecting rod structure 4 can be adjusted by rotating the bolt rod 4-1.

[0022] In this embodiment, one end of the connecting rod structure 4 is hinged to the ground anchor plate 1-3, and the other end is connected to the hinge lug on the coarse sleeve 3-1 in the steel pipe telescopic mechanism 3. One end of the fine sleeve 3-3 in the steel pipe telescopic mechanism 3 is hinged to the ground anchor plate 1-3.

[0023] The key technical features of this solution include a ground anchor plate, a steel pipe telescopic mechanism with an embedded spring, an adjustable-length linkage structure, a semi-circular internal gear ring, a ring gear, and a gear seat with a slide rail. The ground anchor plate is fixed to the ground with expansion bolts. The ground anchor plate has two hinges, which connect the steel pipe telescopic mechanism and the linkage structure respectively. The linkage structure is also connected to the steel pipe telescopic mechanism via hinges. The other end of the steel pipe telescopic mechanism is connected to the gear box 2-1. The guide rail of the gear box 2-1 has a semi-circular internal gear ring 2-2 embedded in it. The position of the semi-circular internal gear ring is indirectly adjusted by rotating the bolts of the linkage structure, so that it is located on the path when the insulation blanket roll bar is lowered. The ring gear is fitted onto the insulation blanket roll bar, ensuring that the ring gear can mesh with the semi-circular internal gear ring.

[0024] When the roller shutter is lowered, the insulation material containing the ring gear is rotated down by the roller rod and falls into the semi-circular inner gear ring. The semi-circular inner gear ring is embedded in the gear box with a semi-circular slide rail. The gear box is fixed to the steel pipe telescopic mechanism. Due to its built-in spring, it can move along the direction of the roller rod's descent.

[0025] Furthermore, the ring gear meshes with the semi-circular inner gear ring. As the ring gear rotates, the semi-circular inner gear slides out within the slide rail of the gear box, causing the opening between the semi-circular inner gear and the slide rail of the gear box to gradually decrease, thus locking the ring gear with the windproof device.

[0026] Furthermore, when the insulation blanket is opened, the insulation blanket reversing mechanism reverses, causing the circular gear to reverse as well. The semi-circular inner gear gradually retracts into the slide rail of the gearbox, and the opening between the semi-circular inner gear and the slide rail of the gearbox gradually increases until it is fully retracted and the opening is larger than the circular gear. The insulation blanket reversing mechanism then disengages from the windproof device.

[0027] The motion principle of this embodiment is as follows:

[0028] When the insulation blanket is lowered, the insulation blanket roll bar 1-1 rotates clockwise, and the ring gear 1-2 fixed to it rotates synchronously. The insulation blanket is lowered into the ring gear 1-2 and falls into the semi-circular inner gear ring 2-2. After it continues to fall, the gears mesh, and the semi-circular inner gear ring 2-2 slides out from the slide rail of the gear box 2-1. This makes the opening between the semi-circular inner gear ring 2-2 and the gear box 2-1 smaller than the diameter of the ring gear 1-2. Therefore, the insulation blanket roll bar 1-1 cannot be dislodged from the windproof device.

[0029] When the insulation blanket is rolled up, the insulation blanket rolling rod 1-1 rotates counterclockwise, and rotates synchronously with the fixed ring gear 1-2. Since the ring gear 1-2 meshes with the semi-circular inner gear ring 2-2, the counterclockwise rotation causes the semi-circular inner gear ring 2-2 to gradually retract into the slide rail of the gear box 2-1, making the opening between the semi-circular inner gear ring 2-2 and the gear box 2-1 larger than the diameter of the ring gear 1-2. Therefore, the insulation blanket rolling rod 1-1 is dislodged from the windproof device.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
