A new type of multifunctional greenhouse

Abstract

This utility model discloses a novel multifunctional greenhouse, aiming to solve the safety hazard of using ladders for fruit harvesting in existing greenhouses. The utility model features a first slide rail and a first sliding frame slidably connected to it on a frame. A second slide rail is rotatably connected to the first sliding frame, and second sliding frames are slidably connected to both sides of the second slide rail. A ladder is fixedly connected to the second sliding frame, and the ladder is equipped with a fixing structure to the ground. Users can use the first slide rail to bring the ladder closer to the fruit tree, then use the second slide rail to bring the ladder closer to the tree, and finally fix it to the ground via the fixing structure to prevent the ladder from shifting position during harvesting. Users can then climb the ladder to harvest the fruit. Because the second sliding frames on both sides are slidably connected to the second slide rails and the ladders are fixed to the ground via the fixing structure, neither ladder will tip over, thus improving harvesting safety.

Description

Technical Field

[0001] This utility model relates to the field of greenhouses, and more specifically, to a new type of multifunctional greenhouse. Background Technology

[0002] A greenhouse is a facility used for growing crops, optimizing plant growth by controlling internal environmental conditions. It can provide more suitable conditions such as temperature, humidity, and light than the outside environment, thereby extending the growing season and increasing yield and quality. A greenhouse generally consists of a frame and a covering layer. The frame is mostly constructed from alloy pipes or plates, and then the frame is covered by a plastic film covering layer.

[0003] Greenhouses are mostly used for growing smaller plants, but some larger fruit trees, such as bayberry trees, are also cultivated in greenhouses. Greenhouse cultivation allows bayberries to ripen earlier, leading to earlier market availability and higher profits, and more and more fruit farmers are starting to cultivate bayberry trees in greenhouses. However, because bayberry trees are tall—around 5 years old they can grow to 3-5 meters or even taller—and bayberries lack a peel, making them easily damaged, mechanical harvesting is difficult; they are primarily harvested manually. Harvesters often need to climb trees or use ladders to reach the higher bayberries. However, since the ground inside the greenhouse is soil, ladders placed on the ground are not very stable. Improper handling at heights can easily cause the center of gravity to shift, leading to the ladder tilting or even tipping over, posing a significant safety hazard. Furthermore, because the ladders are large and require strength and reliability, they are mostly made of alloy or solid wood and are quite heavy. Workers need to frequently adjust the ladder's position while harvesting fruit, which also increases the labor intensity for them.

[0004] However, existing agricultural machinery evaporative fans are often manufactured as a single unit, and are often quite large, making transportation and handling troublesome. Agricultural sites are often complex environments, which can cause some inconvenience to the use of agricultural machinery evaporative fans.

[0005] Based on the above, the purpose of this utility model is to provide a new type of multifunctional greenhouse to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a novel multifunctional greenhouse. This invention features a first slide rail and a first sliding frame slidably connected to it on a frame. A second slide rail is rotatably connected to the first sliding frame, and second sliding frames are slidably connected to both sides of the second slide rail. A ladder is fixedly connected to the second sliding frame, and the ladder is equipped with a fixing structure to the ground. Users can use the first slide rail to bring the ladder closer to the fruit tree, then use the second slide rail to bring the ladder closer to the fruit tree, and finally fix it to the ground via the fixing structure to prevent the ladder from shifting position during harvesting. Users can then climb the ladder to harvest the fruit. Because the second sliding frames on both sides are slidably connected to the second slide rail and the ladders are fixed to the ground via the fixing structure, neither ladder will tip over, improving harvesting safety.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel multifunctional greenhouse, comprising a frame and a covering layer, wherein a first slide rail is fixedly connected to the frame, a first slide frame is slidably connected to the first slide rail, a second slide rail is rotatably connected to the first slide frame, a second slide frame is slidably connected to both sides of the second slide rail, a ladder is fixedly connected to the second slide frame, and a fixing structure is provided on the ladder to fix it to the ground.

[0008] By adopting the above technical solution, when it is necessary to pick fruit from a high place, the user pulls the ladder, causing the first slide to move along the trajectory of the first slide towards the fruit tree to be picked, until the first slide moves above the fruit tree. Then, the user pushes the ladder along the trajectory of the second slide towards the fruit tree, until the ladder moves to the fruit near the outer edge of the fruit tree. Then, the ladder is fixed to the ground by the fixing structure. At this time, the user can climb the ladder to pick the fruit. Since the second slides on both sides are slidably connected to the second slide and the ladders are fixed to the ground by the fixing structure, neither side of the ladder will tip over. After the fruit on one side is picked, the user can release the fixing structure from the ground and push the ladders on both sides in the same direction (e.g., clockwise) so that the ladders on both sides revolve around the fruit tree, thereby adjusting the position of the ladders toward the fruit tree, so that the user can pick the fruit in other parts of the fruit tree.

[0009] The present invention is further configured such that: the fixing structure includes a mounting box fixedly connected to the ladder, a ground nail is slidably connected inside the mounting box, and a driving mechanism for driving the ground nail to move is provided inside the mounting box.

[0010] The present invention is further configured such that: the driving mechanism includes a driving gear rotatably connected to the mounting box; the ground nail is provided with a plurality of tooth grooves that mesh with the driving gear; a worm wheel and a worm are rotatably connected inside the mounting box; the worm wheel and the driving gear are fixedly connected; and the end of the worm away from the worm wheel extends outside the mounting box and is fixedly connected to a rocker arm.

[0011] The present invention is further provided that: both sides of the ladder are provided with fixing structures.

[0012] The present invention is further configured such that the worm gears on both sides of the ladder are connected to each other.

[0013] The present invention is further configured such that the ladder is tilted.

[0014] The present invention is further configured such that both the first slide and the second slide are I-shaped structures.

[0015] The present invention is further configured such that: a plurality of rollers are rotatably connected to both the first slide and the second slide, and the plurality of rollers respectively abut against the top wall and bottom wall of the recessed area on both sides of the first slide or the second slide.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This invention features a first slide rail and a first carriage slidably connected to it on a frame. A second slide rail is rotatably connected to the first carriage, and second carriages are slidably connected to both sides of the second slide rail. A ladder is fixedly connected to the second carriage, and the ladder is equipped with a fixing structure that secures it to the ground. The user can use the first slide rail to bring the ladder closer to the fruit tree, then use the second slide rail to bring the ladder closer to the fruit tree, and finally fix it to the ground through the fixing structure to prevent the ladder from shifting position during harvesting. At this point, the user can climb the ladder to harvest the fruit. Since the second carriages on both sides are slidably connected to the second slide rail and the ladders are fixed to the ground through the fixing structure, neither ladder will tip over, thus improving the safety of harvesting.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] A new type of multifunctional greenhouse, such as Figures 1-4 As shown, it includes a frame 1 and a covering layer. Several crossbeams are welded on the frame. A first slide rail 3 is fixedly connected between the multiple crossbeams of the frame 1. A first slide frame 4 is slidably connected to the first slide rail 3. A second slide rail 5 is rotatably connected to the first slide frame 4. A second slide frame 6 is slidably connected to both sides of the second slide rail. A ladder 7 is fixedly connected to the second slide frame 6. The ladder 7 is provided with a fixing structure to fix it to the ground.

[0028] Furthermore, the fixing structure includes a mounting box 8 fixedly connected to the ladder 7, a ground nail 9 slidably connected inside the mounting box 8, and a drive mechanism for moving the ground nail 9 inside the mounting box 8.

[0029] Furthermore, the drive mechanism includes a drive gear 10 rotatably connected to the mounting box 8. The ground nail includes a nail head portion and a connecting rod portion. The connecting rod portion has a polygonal structure. In this embodiment, the connecting rod portion is square. The connecting rod portion of the ground nail 9 has several toothed grooves 11 that mesh with the drive gear 10. The mounting box 8 also has a worm gear 12 and a worm 13 that mesh with each other. The worm gear 12 and the drive gear 10 are fixedly connected. The end of the worm 13 away from the worm gear 12 extends outside the mounting box 8 and is fixedly connected to a rocker arm 14.

[0030] Furthermore, both sides of the ladder 7 are equipped with fixing structures.

[0031] Furthermore, the worm gears 13 on both sides of the ladder 7 are fixedly connected to each other.

[0032] Furthermore, ladder 7 is tilted.

[0033] Furthermore, both the first slide rail 3 and the second slide rail 5 are I-shaped structures.

[0034] Furthermore, several rollers 15 are rotatably connected to both the first slide 4 and the second slide 6. The rollers 15 respectively abut against the top and bottom walls of the recesses on both sides of the first slide or the second slide 5. Cover plates are detachably connected to both sides of the second slide. The cover plates are fixedly connected to the second slide by multiple bolts. The cover plates can block the second slide and prevent the second slide from accidentally sliding out.

[0035] Working principle: When it is necessary to pick fruit from a high place, the user pulls the ladder 7, causing the first slide 4 to move along the track of the first slide 3 towards the fruit tree to be picked, until the first slide 4 moves to the top of the fruit tree. Then, the user pushes the ladder 7 along the track of the second slide 5 towards the fruit tree, until the ladder 7 moves close to the fruit near the outer edge of the fruit tree. Then, the user rotates the rocker arm 14, which drives the two worm gears 13 to rotate. The rotating worm gear drives the worm wheel 12 to rotate, and the worm wheel 12 drives the drive gear 10 to rotate. The drive gear 10 drives the ground nail 9 to move downward through the tooth groove 11, until the ground nail 9 is driven into the ground to a certain depth, fixing the ladder 7 to the ground. At this time, the two sides of the ladder 7 and the first slide 4 at the top form a three-point support, which prevents the ladder 7 from tipping over and improves the safety of the ladder 7 when using it.

[0036] At this point, the user can climb the ladder 7 to pick the fruit. The inclined ladder 7 makes climbing easier, and during the picking process, the user can lean against the ladder 7, which provides some support and reduces physical exertion and fatigue. The user can lean against the ladder 7, hang the fruit basket on it, and then reach through the slots on the sides or in the middle of the ladder 7 to pick the fruit. The picked fruit is then placed in the basket. To elaborate, the basket for picking fruit from higher places is usually round, with a hanging rope fixed to both ends. A hook is fixed to the middle of the hanging rope, allowing the basket to be hung on the ladder 7 or a tree branch, making it convenient for the user to climb the ladder 7 or the fruit tree to pick the fruit.

[0037] After the fruit on one side has been harvested, the user can rotate the lever 14 on both sides of the ladder 7 in the opposite direction to remove the ground nail 9 from the ground, and then push both sides of the ladder 7 in the same direction (e.g., clockwise) to make the ladder 7 revolve around the fruit tree, thereby adjusting the position of the ladder 7 toward the fruit tree so that the user can harvest the fruit in other parts of the fruit tree.

[0038] This design, with its non-tipping ladder 7, enhances the safety of fruit harvesting and reduces the need for workers to frequently move it, thus lowering their workload. Furthermore, the ladder 7 is frequently used in fruit tree maintenance, such as during pruning (removing overly dense branches to allow fruit in the inner part of the tree to receive sunlight) and fruit sifting (removing excess fruit buds to allow the remaining buds to receive more nutrients, ensuring the quality of the fruit later). These uses make fruit tree maintenance safer and more convenient.

[0039] It should be mentioned that this scheme requires frame 1 to support components such as the first slide 3, the first carriage 4, and the ladder 7, which requires a certain level of support strength. Therefore, frame 1 and the crossbeams need to be constructed using high-strength profiles, such as high-strength I-beams. Constructing the main frame and crossbeams with high-strength I-beams is a mature existing technology, such as the construction of steel shed factories, which will not be elaborated here. Then, metal pipes are welded to the main frame to fill the space between the I-beams and to build the top of the frame. Increasing the pipe density facilitates the subsequent fixing of the covering layer. This setup improves the overall strength of frame 1 and enhances its resistance to natural disasters. However, the cost will be slightly higher than that of traditional greenhouses, and the fruit trees need to be planted in a standardized manner along the trajectory of the first slide 3.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
