Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shed frames, and specifically relates to an adjustable lifting shed frame. Background Art
[0002] In modern agricultural production, the application of shed frames is becoming increasingly widespread. The framework of a shed frame is usually composed of tie rods, press rods, columns, arch rods, etc. made of greenhouse composite materials, and is covered with plastic film to provide a suitable growth environment for growing crops.
[0003] However, in heavy snow weather, existing shed frames are easily subjected to the huge pressure brought by accumulated snow. Due to the limited load-bearing capacity of the shed frame structure, it is very easy to be collapsed by the snow; once this situation occurs, it will not only directly damage the crops, resulting in a decrease in agricultural product yield and quality, bringing huge economic losses to farmers, but also affect the normal progress of agricultural production, disrupting the planting plan and market supply.
[0004] For liftable shed frames, the situation is more complicated. When a certain amount of snow accumulates on the top, the heavy snow will damage the lifting mechanism inside the shed frame; for example, the lifting components may be deformed, bent or even broken due to excessive pressure, resulting in the failure of the lifting function, which not only increases the maintenance cost, but also cannot adjust the height of the shed frame in time in case of emergency, and cannot effectively cope with bad weather and environmental changes.

Detailed implementation mode
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Please refer to Figure 1-7 , the present invention provides a technical solution for a liftable and adjustable greenhouse frame:
[0025] According to Figure 1-7 As shown, a liftable and adjustable greenhouse frame includes a plurality of lifting rods 1 evenly spaced apart. The tops of two longitudinally coaxially arranged lifting rods 1 are fixedly connected to the same arch rod 2. A plastic film is laid on the arch rod 2. Among them, the tops of the two lifting rods 1 at the frontmost and the rearmost are fixedly connected to the same rack guide rod 3 and the same sliding guide rail 4. It can be seen that the two rack guide rods 3 are located on the inner side, and the two sliding guide rails 4 are located on the outer side; Figure 1 It can be seen that the two rack guide rods 3 are located on the inner side, and the two sliding guide rails 4 are located on the outer side;
[0026] The two rack guide rods 3 are both meshed with driving gears 5, and the centers of the two driving gears 5 are fixedly connected to a unified transmission shaft 6. The left and right ends of the transmission shaft 6 are symmetrically connected to mounting plates 7 for rotation, and a plurality of wiping sponges 8 are rotatably sleeved in the middle. Furthermore, a rod cleaning brush 13 is rotatably installed on the two mounting plates 7. The two ends of the transmission shaft 6 and the rod portion of the rod cleaning brush 13 are connected through a conveyor belt 12. The rotation of the transmission shaft 6 drives the rod cleaning brush 13 to rotate synchronously, and the rack guide rod 3 is cleaned back and forth to prevent snow from accumulating in the rack guide rod 3 and affecting the operation of the entire cleaning device. The transmission shaft 6 is composed of two connecting rods A, a plurality of connecting rods B and a plurality of bolts 63. The two connecting rods A are connected to the It is called a setting, which passes through and is fixedly connected to the driving gear 5, and is equipped with multiple connecting rods B in the middle. Each connecting rod B is sleeved with a section of wiping sponge 8, and the multiple connecting rods are connected to each other by bolts 63. The connecting rod A and the connecting rod B are assembled together by bolts 63 to form a transmission shaft, which is also convenient for disassembly. For example, if a section of the wiping sponge 8 is damaged and worn and needs to be replaced, the corresponding connecting rod B can be removed and replaced in time to ensure that the entire device can run longer. Furthermore, the left and right ends of the connecting rod B are respectively fixed with plug handles and slots 65, and the opposite ends of the two connecting rods A are respectively fixed with plug handles and slots 65, which makes it convenient to splice the connecting rod A and the connecting rod B together to complete the assembly.
[0027] Four rotating bolts 10 are rotatably mounted below the two mounting plates 7, wherein a driving motor 9 is fixedly connected to the outer wall of the mounting plate 7 at the front end, and the output shaft of the driving motor 9 is fixedly connected to the transmission shaft 6. Each rotating bolt 10 is rotatably sleeved on one side thereof, and the roller 11 slides in the inner groove of the sliding guide rail 4, and the rotating bolt 10 is connected to the outer wall of the mounting plate 7 at the front end, and the output shaft of the driving motor 9 is fixedly connected to the transmission shaft 6. Figure 3 and Figure 4 The sliding guide rail 4 has two inner grooves symmetrically arranged inside and outside, two rollers 11 are installed in the inner grooves on the outer side of the sliding guide rail 4, and two rollers 11 are installed in the inner grooves on the inner side of the sliding guide rail 4.
[0028] During specific use, the driving motor 9 rotates the transmission shaft 6, which drives the two driving gears 5 to rotate through the transmission shaft 6. Since the driving gear 5 is meshed with the rack guide rod 3, the driving gear 5 rolls back and forth on the rack guide rod 3, thereby driving the transmission shaft 6 and the wiping sponge 8 to move back and forth, so that the snow on the plastic film is cleaned in time. The movement of the transmission shaft 6 also drives the mounting frame to move, that is, drives the rollers 11 on all the rotating bolts 10 to move, and the mounting frame is limited on the sliding guide rail 4 through the rollers 11. The rollers 11 also facilitate the reciprocating motion of the wiping sponge 8.
[0029] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present utility model to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present utility model.
