Description

Technical Field

[0001] This utility model relates to the field of vegetable greenhouse frame technology, specifically a vegetable planting greenhouse frame system. Background Technology

[0002] Greenhouses are an indispensable facility in vegetable cultivation. They are used to control the temperature and humidity required for vegetables. Greenhouses are divided into plastic film greenhouses and glass greenhouses. Glass greenhouses are generally suitable for large companies to grow some special products, while plastic film greenhouses are still the mainstream facility. The current plastic film greenhouses are mainly composed of several arched roofs and support rods. When encountering particularly severe storms, they are prone to collapse and overturning.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a vegetable greenhouse frame system. Utility Model Content

[0004] The technical problem solved by this utility model is to propose a vegetable greenhouse frame system.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vegetable greenhouse frame system, comprising several equidistantly arranged arc-shaped roofs and several supporting beams for the arc-shaped roofs. A crossbeam is welded to the bottom of each arc-shaped roof, and the supporting beams are welded to both sides and the middle of the bottom of the crossbeams. Several reinforcing beams are welded between the supporting beams and the crossbeams, and a sleeve is fitted over the supporting beams. A tie rod is connected to the bottom of the sleeve, and a counterweight is connected to the bottom of the tie rod.

[0006] Furthermore, the two ends of the counterweight are connected to suspension rods, and hooks are welded onto the suspension rods. The suspension rods are connected to the counterweight via hooks at their tops.

[0007] Furthermore, the counterweight base consists of an upper plate and a lower plate, which are connected by several U-shaped plates. A drive sprocket and a driven sprocket are respectively installed at both ends of the upper and lower plates. A chain meshes between the drive sprocket and the driven sprocket. A connecting seat is hinged on the chain. A hook hole seat is provided on the connecting seat. The hook at the top of the suspension rod is hooked onto the hook hole seat.

[0008] Furthermore, rollers are installed at both the upper and lower ends of the connecting seat, and the upper and lower rollers contact the upper plate and the lower plate respectively.

[0009] Furthermore, the suspension rod includes an upper rod and a lower rod, which are connected by a sleeve. The contact surfaces of the upper and lower rods are provided with teeth arranged at equal intervals from top to bottom. The teeth of the upper rod and the teeth of the lower rod mesh with each other. The top of the lower rod is provided with a plug, the length of which is greater than the diameter of the sleeve.

[0010] Furthermore, diagonal tie rods are connected to both sides of the support beam.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the greenhouse frame has an added counterweight system, which makes the center of the greenhouse top face downwards and generates a reverse pulling force on the greenhouse top to ensure the greenhouse's resistance to pressure. At the same time, the counterweight system can be used as a conveying structure inside the greenhouse, so that the harvested vegetables can be transported outside the greenhouse during harvesting.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution:

[0020] like Figure 1-6As shown, a vegetable greenhouse frame system includes several equidistantly arranged arc-shaped roofs 1 and several supporting beams 3 for the arc-shaped roofs 1. A crossbeam 2 is welded to the bottom of the arc-shaped roof 1. The supporting beams 3 are welded to the bottom sides and the middle of the crossbeam 2 respectively. Several reinforcing beams 4 are welded between the supporting beams 3 and the crossbeams 2. The supporting beams 3 are covered with sleeves 5, which are formed by two semi-circular rings joined together and then fixed tightly with bolts and nuts. A tie rod 6 is connected to the bottom of the sleeve 5, and a counterweight 7 is connected to the bottom of the tie rod 6. The tie rod 6 causes the counterweight 7 to face downward and maintain a distance from the roof. In the event of a storm, the counterweight 7 pulls the arc-shaped roof 1 from below to prevent it from tipping over and collapsing. At the same time, diagonal tie rods 10 are connected to both sides of the supporting beams 3, so that each arc-shaped roof 1 has an individual additional support, further improving the stability of the frame.

[0021] Based on the above, the two ends of the counterweight seat 7 are connected to suspension rods 8, and hooks 9 are welded on the suspension rods 8. The suspension rods 8 are connected to the counterweight seat 7 through the hooks at their top. In addition to generating counterweight on the frame in the counterweight seat 7, the suspension rods 8 and hooks 9 can be used to suspend additional counterweights, further increasing the tension on the ceiling.

[0022] Based on the above, the counterweight seat 7 can not only be used as a counterweight, but also as a transportation structure in a greenhouse. Specifically, the counterweight seat 7 is composed of an upper plate 71 and a lower plate 72. The upper plate 71 and the lower plate 72 are connected by several U-shaped plates 78. The shape of the U-shaped plates 78 is to make room for the chain 74. The two ends between the upper plate 71 and the lower plate 72 are respectively equipped with a drive sprocket 73 and a driven sprocket. The drive sprocket 73 and the driven sprocket are meshed with a chain 74. A connecting seat 75 is hinged on the chain 74. The connecting seat 75 is provided with a hook hole seat 77. The hook at the top of the suspension rod 8 is hooked on the hook hole seat 77.

[0023] Both the upper panel 71 and the lower panel 72 are made of modular splicing;

[0024] When harvesting inside the greenhouse, the suspension rod 8 is hung on the hook hole seat 77 of the chain 74 at the greenhouse entrance. The suspension rod 8 moves in a cycle with the chain 74, and the baskets full of harvested vegetables can be hung on the suspension rod 8 using the hook head 9. With the movement of the chain 74, the baskets full of harvested vegetables are transported to the greenhouse entrance.

[0025] To ensure stability, rollers 76 are installed at both the upper and lower ends of the connecting seat 75. The upper and lower rollers 76 contact the upper plate 71 and the lower plate 72 respectively. That is, during conveying, the upper and lower rollers 76 roll with the upper plate 71 and the lower plate 72 respectively, thereby supporting the chain 74 and preventing the chain 74 from sinking due to pressure.

[0026] In order to make it easier and faster to hang the basket on the suspension rod 8, the suspension rod 8 is designed to be telescopic. The suspension rod 8 includes an upper rod 81 and a lower rod 82. The upper rod 81 and the lower rod 82 are connected by a sleeve tube 83. The contact surfaces of the upper rod 81 and the lower rod 82 are provided with teeth 84 arranged at equal intervals from top to bottom. The teeth 84 of the upper rod 81 and the teeth 84 of the lower rod 82 mesh. The top of the lower rod 82 is provided with a plug. The length of the plug is greater than the diameter of the sleeve tube 83.

[0027] Slightly lift the lower rod 82 upwards, away from the upper rod 81, so that the teeth 84 of the rod 81 and the lower rod 82 separate, then the lower rod 82 can be lowered. Then hook the bottom hook 9 on the lower rod 82 onto the basket, and then lift the lower rod 82 upwards. This method is easier than lifting the basket directly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
