Description

Technical Field

[0001] The invention relates to the technical field of greenhouse frames, and in particular to an assembled greenhouse frame structure. Background Art

[0002] The existing greenhouse structure is simple, and mainly relies on the greenhouse frame to resist external pressure. In northern my country, due to climatic reasons, heavy snow often falls, and the plastic film covering the greenhouse frame directly contacts the snow and forms accumulation. Therefore, it is necessary to clear the snow on the greenhouse every once in a while. However, there are sudden blizzards at night, which make it impossible for farmers to clear the snow in time. At this time, if the snow is too thick, it exceeds the load-bearing capacity of the greenhouse, and the frame is easily squeezed, deformed or even collapsed, reducing the service life of the greenhouse and causing economic losses to farmers. For this reason, we propose an assembled greenhouse frame structure. Summary of the invention

[0042] Both sides of the fixing frame 31 are bent structures. The positioning assembly 4 includes two positioning blocks 41 respectively arranged on both sides of the hollow rod 9. Both sides of the fixing frame 31 are provided with a plurality of locking members 5 matched with the positioning blocks 41 for locking and positioning the positioning blocks 41. Both sides of the fixing frame 31 are provided with guide members 6 for driving the hollow rod 9 and the positioning blocks 41 on both sides to shift relative to the inclined beam 24.

[0043] The fixing frame 31 is provided with a through hole, and the locking member 5 includes a positioning cylinder 51 arranged on the fixing frame 31, the positioning cylinder 51 is arranged coaxially with the through hole, a pressing spring 52 is arranged in the positioning cylinder 51, a locking ball 53 is arranged at the end of the pressing spring 52, and a slot 54 engaged with the locking ball 53 is provided on the positioning block 41;

[0046] Synchronous cutting units 7, multiple synchronous cutting units 7 are provided and are respectively arranged on the top frame 2. When the gravity adjustment unit 3 is working, the adjacent cutters 10 are driven to rise in the hollow rod 9 and cut the top of the greenhouse film along the hollow rod 9 to prevent the top frame 2 and the column 1 from being crushed;

[0047] A rectangular hole is provided at the bottom of the hollow rod 9, and the synchronous cutting unit 7 includes an extrusion block 71 slidably arranged in the rectangular hole, a sliding seat 72 is provided on the extrusion block 71, and the cutter 10 is arranged on the top of the sliding seat 72. A cutting groove 73 is provided at the top of the hollow rod 9, and a plurality of rubber pads 74 are provided at the top of the hollow rod 9. The plurality of rubber pads 74 are respectively located on both sides of the cutting groove 73. A driving member 8 connected to the sliding seat 72 is provided at the lower end of the inclined beam 24, and is used to drive the cutter 10 to shift along the hollow rod 9 after the hollow rod 9 shifts.

[0048] The driving member 8 includes a guide wheel 81 arranged on the inclined beam 24, a support rod 82 is arranged on the inclined beam 24, a wire rope 83 is arranged on the support rod 82, the wire rope 83 passes through the guide wheel 81 and is connected to the sliding seat 72, a movable pulley 84 is arranged on the wire rope 83, and a weight 85 is arranged at the bottom of the movable pulley 84.

[0049] When in use, farmers connect and position the upright column 1, the cross beam 21 and the diagonal beam 24 through the connecting plate and bolts according to the land size.

[0050] When a sudden snowstorm occurs, the accumulated snow will continue to increase. Before it exceeds the limit of the frame, the hollow rod 9 and the connecting rod 11 will be squeezed down, so that the extrusion block 71 at the bottom will contact the inclined beam 24 and be squeezed up. At the same time, the cutter 10 at the top will also be squeezed out of the cutting groove 73, and at the same time, this part of the greenhouse film will be cut open. After the extrusion block 71 is squeezed into the hollow rod 9, it will move downward along the hollow rod 9 under the action of the weight 85, so that the greenhouse film at the position of the hollow rod 9 will be cut open, and the snow on it will fall under its own gravity, thereby reducing the pressure on the greenhouse frame, and to a certain extent reducing the economic losses of farmers.

[0051] Example 2: Please refer to Figure 10-11 , the present invention provides a technical solution:

[0052] Different from the first embodiment, a roller 12 is disposed at the bottom of the extrusion block 71 , and a ball 13 is disposed at the top of the sliding seat 72 .

[0053] When in use, farmers connect and position the upright column 1, the cross beam 21 and the diagonal beam 24 through the connecting plate and bolts according to the land size. After installation, take a hollow rod 9 and snap the positioning blocks 41 on it onto the fixing frame 31 respectively, so that the locking ball 53 snaps into the slot 54 to complete the locking and positioning. Finally, the connecting rod 11 is installed between the hollow rod 9 and the adjacent hollow rod 9 on the adjacent diagonal beam 24 to complete the positioning of the entire skeleton.

[0054] When a sudden snowstorm occurs, the accumulated snow will continue to increase. Before it exceeds the limit of the frame, the hollow rod 9 and the connecting rod 11 will be squeezed down, so that the extrusion block 71 at the bottom will contact the inclined beam 24 and be squeezed up. The roller 12 at the bottom of the extrusion block 71 will contact the bottom of the hollow rod 9. At the same time, the ball 13 at the top will also contact the bottom of the hollow rod 9, reducing the friction when the sliding seat 72 slides down. At the same time, the top cutter 10 is also squeezed out of the cutting groove 73, and at the same time, this part of the greenhouse film is cut open. After the extrusion block 71 is squeezed into the hollow rod 9, it will move downward along the hollow rod 9 under the action of the weight 85, so that the greenhouse film at the position of the hollow rod 9 is cut open, and the snow on it will fall under its own gravity, thereby reducing the pressure on the greenhouse frame and, to a certain extent, alleviating the economic losses of farmers.
