Description

Technical Field

[0001] The invention relates to the technical field of antifreeze shed devices, and in particular to an antifreeze shed device for preventing frost damage during apple flowering period. Background Art

[0002] A frost-proof shed is a protective facility used to protect crops, plants or other items from freezing damage in low-temperature environments. It is commonly used in agriculture, horticulture or specific industrial scenarios. Covering materials (such as plastic film, insulation quilts, straw curtains, etc.) are used to reduce heat loss, maintain the temperature inside the shed higher than the external environment, and prevent plants from being frozen or dying due to low temperatures; Apple blossoms (especially in northern regions) often encounter disastrous weather such as low temperatures and frost, which damages the flower organs, reduces the fruit setting rate, and even causes a total crop failure. Therefore, it is usually necessary to build a frost-proof shed to protect against the effects of low temperatures. However, in the use of antifreeze sheds, plastic film is often needed for protection in low temperature weather, but the plastic film must be removed after the weather warms up to avoid damage to trees in high temperature and high humidity environment. Existing antifreeze shed devices often lay the plastic film in one piece, and because the plastic film is too long and too large, it requires multiple people to complete the laying process. At the same time, after laying, it needs to be connected to the frame and limited to prevent it from being blown away by the wind later. However, not only the laying process but also the subsequent limiting process requires the assistance of multiple people and consumes a lot of time. Summary of the invention

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] See also Figure 1-10 , an antifreeze shed device for preventing frost damage during apple flowering period, comprising a base plate 1, on which a vertical pole 2 is fixedly mounted, and further comprising: Winding shaft 3; A rotating rod 51 is rotatably mounted on the vertical rod 2, and a magnet 53 is movably disposed on the top of the rotating rod 51, and the magnet 53 is vertically slidably mounted on the vertical rod 2; The insertion rod 52 is horizontally slidably mounted on the vertical rod 2, and the insertion rod 52 passes through the vertical rod 2, and one end of the insertion rod 52 is provided with an inclined surface; The protrusion 55 is fixedly mounted on the insertion rod 52, and the inner wall of the rotating rod 51 is provided with a spiral groove 57 that matches the protrusion 55; When the winding shaft 3 moves to unwind the plastic film, the plurality of magnets 53 will be passively caused to slide downward in sequence to pre-fix the flat plastic film; When the plastic film wound on the winding shaft 3 is unrolled, the winding shaft 3 first enters the vertical pole 2 and moves along the horizontal end of the vertical pole 2. As the winding shaft 3 moves horizontally, the plastic film will unfold first. At the same time, the winding shaft 3 will contact the inclined surface of the insertion rod 52. At this time, the inclined surface of the insertion rod 52 will be squeezed and move toward the inside of the vertical pole 2, and the protrusion 55 on the insertion rod 52 will move in the spiral groove 57, thereby driving the rotating rod 51 to rotate through the spiral groove 57. As the rotating rod 51 rotates, its top end will descend, thereby driving the magnet 53 to descend. As the magnet 53 slides down, its bottom end will be pressed on the plastic film and adsorbed on the inner bottom wall of the top end of the vertical pole 2, thereby pre-limiting the plastic film.

[0020] In another embodiment of the present invention: a through hole 8 and a film laying channel 9 connected to the through hole 8 are formed at the top of the vertical pole 2, and the height of the inner wall of the film laying channel 9 gradually decreases from the middle to both sides; The length of the winding shaft 3 is matched with the spacing size of the film laying channel 9 between the two vertical poles 2, so the winding shaft 3 is placed into the film laying channel 9 from the through hole 8 at the top of the vertical pole 2, and the two ends of the winding shaft 3 will fit with the inner walls of the two film laying channels 9, so the movement of the winding shaft 3 will squeeze the insertion rod 52 so that the insertion rod 52 slides toward the vertical pole 2, and the plastic film wound on the winding shaft 3 will be wrapped around the winding shaft 3 when it is first laid, which will cause the overall diameter of the winding shaft 3 to be larger. Therefore, when it is first placed in the film laying channel 9, it will first move at a higher place, and as the plastic film unfolds, the overall diameter of the winding shaft 3 decreases, and at this time it will slowly enter the film laying channel 9.

[0021] In another embodiment of the present invention: a pressure rod 41 is horizontally slidably mounted on the vertical rod 2, a slide rod 42 is fixedly mounted on the pressure rod 41, and a screw rod 43 is threadedly inserted on the slide rod 42; The pressure rod 41 is located at the center of the vertical rod 2, and there are two pressure rods 41 between the two vertical rods 2. When the plastic film on the winding shaft 3 is unfolded, the opening end of the plastic film is first placed between the two pressure rods 41, and then the screw 43 is tightened and the nut is used to fasten the two pressure rods 41 together, thereby locking the opening end of the plastic film.

[0022] In another embodiment of the present invention: a rotating drum 56 is fixedly mounted on the rotating rod 51, and the rotating drum 56 is hollow; The insertion rod 52 passes through the rotating rod 51 and the rotating drum 56 , and the rotating drum 56 is rotatably connected to the vertical rod 2 , so the rotation of the rotating rod 51 is achieved through the rotating drum 56 .

[0023] In another embodiment of the present invention: a long plate 54 is horizontally slidably mounted on the upright pole 2; Two symmetrically arranged long plates 54 are provided on the vertical pole 2. When the winding shaft 3 moves to push the insertion rod 52 to move toward the vertical pole 2, one end of the insertion rod 52 will fit with the long plate 54. When the magnet 53 needs to be raised, the long plate 54 is slid so that it squeezes multiple insertion rods 52 at the same time, so that the insertion rod 52 moves in the opposite direction, thereby driving the insertion rod 52 to drive the rotating rod 51 to rotate upward to raise the magnet 53.

[0024] In another embodiment of the present invention: a rotating bar 73 is rotatably mounted on the vertical rod 2, and an extrusion block 71 is fixedly mounted on the rotating bar 73, and a disc 72 is fixedly mounted on the rotating bar 73; One set of long plates 54 is provided with two. When the long plates 54 need to be slid to squeeze the insertion rods 52, the rotating bar 73 is rotated by the disc 72, so that the two squeezing blocks 71 on the rotating bar 73 squeeze the long plates 54 at both ends at the same time, so that the two long plates 54 move at the same time to push the plurality of insertion rods 52. The insertion rod 52 is horizontally slidably mounted on the vertical rod 2, so that the insertion rod 52 will not rotate at will.

[0025] In another embodiment of the present invention: a side plate 64 is vertically slidably mounted on the upright pole 2, a top plate 63 is fixedly mounted on the side plate 64, a side rod 62 is fixedly mounted on the top plate 63, and a first limit strip 61 is rotatably mounted on the bottom end of the side rod 62; A friction wheel 66 is rotatably mounted on the vertical rod 2, and the friction wheel 66 is fitted with the side plate 64. A second limit bar 65 is horizontally slidably mounted on the vertical rod 2, and a friction bar 67 is fixedly mounted on the second limit bar 65, and the friction bar 67 is fitted with the friction wheel 66. When the side plate 64 slides downward, it will drive the friction wheel 66 to rotate, and the friction wheel 66 will drive the friction strip 67 to slide horizontally. At this time, the friction strip 67 will drive the second limit strip 65 to squeeze the vertically laid plastic film. At the same time, the downward movement of the side plate 64 will drive the first limit strip 61 to move downward through the top plate 63 and the side rod 62. At this time, the first limit strip 61 will squeeze and limit the horizontally laid plastic film. At this time, the first limit strip 61 and the second limit strip 65 are in a vertical state to fully squeeze and limit the laid plastic film. Furthermore, rubber pads are fixedly mounted on the first limiting strip 61 and the second limiting strip 65, so that the extrusion limiting effect is better and the sealing effect is also better; Furthermore, a tooth block is fixedly mounted on the friction strip 67, and a tooth groove is provided on the friction wheel 66. The cooperation between the tooth block and the tooth groove makes it convenient to drive the friction strip 67 to move when the friction wheel 66 rotates. An embedded groove is provided on the film laying channel 9 of the vertical pole 2, and the embedded groove is used to accommodate the first limiting strip 61. When the first limiting strip 61 is moved up for accommodation, it will move into the embedded groove. At this time, the first limiting strip 61 is squeezed by the embedded groove in an inclined state so as to rotate and adapt to be completely accommodated in the embedded groove.

[0026] In another embodiment of the present invention: a limit rod 610 is fixedly installed on the top of the vertical rod 2, and the top plate 63 is vertically sleeved on the limit rod 610; The limiting rod 610 is used to limit the vertical sliding of the top plate 63 to prevent it from rotating.

[0027] In another embodiment of the present invention: a pedal 68 is fixedly mounted on the bottom end of the side plate 64, and a plug strip 69 is horizontally slidably inserted on the pedal 68; When the plastic film is laid, the side plate 64 can be slid downward by the pedal 68 , and the side plate 64 will move downward until the side plate 64 moves to the bottom. At this time, the insert 69 is inserted into the vertical pole 2 or the base plate 1 to limit the movement of the side plate 64 .

[0028] In another embodiment of the present invention: a groove 58 is formed on the rotating rod 51, a round bar is fixedly mounted on the magnet 53, and the size of the round bar matches the size of the groove 58; When the rotating rod 51 descends, it will drive the round bar to descend through the groove 58, and one end of the round bar slides vertically on the vertical rod 2. Therefore, when the round bar descends, it will drive the magnet 53 to descend vertically. The groove 58 is long, so it is convenient for the round bar to move in the groove 58 while descending to avoid getting stuck.

[0029] Working principle: When it is necessary to prevent frost damage, first insert the winding shaft 3 with the plastic film from the top through hole 8 of the vertical pole 2 into the film laying channel 9. At this time, both sides of the winding rod are in contact with the two side walls of the film laying channel 9. Then, the free end of the plastic film is clamped by the pressure rod 41 for limiting. Then, the winding shaft 3 is moved in the film laying channel 9 to slowly unfold. While unfolding, the winding shaft 3 will push the insertion rod 52 to move so that the rotating rod 51 rotates, thereby driving the magnet 53 to fall. The inner bottom wall of the film laying channel 9 is provided with an iron sheet. When the magnet 53 falls, it will be adsorbed on The bottom end of the film laying channel 9 can absorb the unfolded plastic film to prevent it from falling due to gravity, so that one person can lay the plastic film without the help of too many people. After the plastic film is completely laid, the first limit strip 61 and the second limit strip 65 are used to limit the entire plastic film, and during the limiting process, it is only necessary to press the pedal 68 to limit the first limit strip 61 and the second limit strip 65 to limit the plastic film, and then insert the insert strip 69 into the vertical pole 2 or the base plate 1 to clamp it to limit the movement of the side plate 64, thereby making it easier to limit the plastic film.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
