Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a portable ladder suitable for use in a greenhouse. BACKGROUND

[0002] In modern agriculture, planting crops in a greenhouse has been widely applied. In order to provide a suitable growth environment for crops, high-altitude operations such as opening and closing air vents, repairing membranes, hanging equipment in the greenhouse, and maintenance often need to be performed in the greenhouse. At this time, ladders and stools need to be used. However, due to the limited space in the greenhouse, the existing ladders are too large in size, which makes it extremely inconvenient to use, carry, and store the ladders in the greenhouse. In addition, the ladders are likely to collide with the support columns of the greenhouse, causing damage to the support columns. Furthermore, the ground in the greenhouse is muddy and complex, and may have accumulated water and loose soil. When one end of the ladder is placed on the ground, the ladder is likely to slide on the ground or sink into the soil, causing the other end of the ladder to slide on the support columns. When a person operates on the ladder, there is a risk of personal safety, and the crops may be damaged. Ordinary stools are inconvenient to use in the greenhouse because their height cannot be adjusted.

[0003] Therefore, there is an urgent need for a ladder that is designed specifically for the environment of a greenhouse and has the characteristics of portability, stability, and small space occupation, in order to solve the practical problems in the greenhouse operations.

The number of the steps 4 can be set according to the length of the ladder body, so as to increase the stability of the overall structure and facilitate the workers to operate.

[0032] As shown in Figure 2 The buckle 1 includes a clamping part and a supporting part. The clamping part is arranged on the top of the supporting part and has a Hengyang structure with one side opening. Such structure of the buckle facilitates the adjustment of the connection between the ladder body and the stand column in the greenhouse and enhances the stability of the overall structure. The opening on one side of the clamping part facilitates the quick installation and disassembly of the ladder body 3 and the stand column in the greenhouse. The supporting part has a Hengyang structure and can provide auxiliary support to increase the stability. The clamping part and the supporting part are connected by welding, thereby enhancing the overall stability of the buckle. The length of the opening on one side of the clamping part is greater than the cross-sectional width of the stand column, so that the ladder body is connected with the stand column through the opening of the clamping part. The size of the clamping part is consistent with that of the supporting part, thereby enhancing the stability of the buckle.

[0033] As shown in Figure 3 The supporting part in the buckle 1 is provided with a bearing 2 through the top of the ladder body 3, so as to realize the rotational connection between the buckle 1 and the ladder body 3, connect the buckle 1 and the stand column in the greenhouse, thereby clamping the ladder body 3 on the stand column, and adjust the inclination angle of the ladder body 3 and the stand column by adjusting the rotation of the buckle 1 around the bearing 2, which is convenient for subsequent operation of the operator.

[0034] As shown in Figure 4 The clamping part in the buckle 1 has a Hengyang structure with one side opening, and the inner surface of the clamping part is provided with a thread 5, which effectively increases the friction between the clamping part and the stand column, ensures that the clamping part will not fall off the stand column, and has very high stability and supporting force.

[0035] In some other embodiments, the materials of the ladder body 3, the buckle 1 and the step 4 are all alloys, so as to make the overall quality light, facilitate the transportation and ensure the stability of the overall structure.

[0036] The utility model discloses a typical embodiment, with the common big -arch shelter stand column cross section width 5cm, long 10cm as an example, the utility model buckle 1's width is 17cm, and the diameter of the material for buckle is 2cm, and the material is cylinder, and the one side opening of the clamping piece in buckle is 8cm, and the support piece is 12cm. The material thickness of the both sides board of ladder body 3 is 0.3cm, and the sideboard length is 50cm, and the sideboard width is 11cm. The material thickness of step 4 is 0.3cm, and the length of step 4 is 15cm, and the width of step 4 is 11cm. Through the size setting, the ladder prepared by the utility model is small and can be supported on the stand column, is stable, and will not damage the crops in the big -arch shelter, is convenient to carry and store. Meanwhile, by adjusting the clamping height of buckle 1 and the stand column, the relative height of the whole ladder on the stand column is adjusted, so that the operation of the operator at different heights is satisfied.

[0037] Working principle

[0038] The buckle 1 in the utility model is connected through the top bearing 2 of the ladder body 3, and the buckle 1 is rotatably connected with the ladder body 3, having two working states of opening and folding. When the buckle 1 is rotated upward through the top bearing 2 of the ladder body 3, it is in the opening state. In the opening state, the buckle 1 is connected with the stand column in the big -arch shelter through the one side opening of the clamping piece, so that the connection between the ladder body and the stand column in the big -arch shelter is realized. Meanwhile, the connection angle of the ladder body and the stand column in the big -arch shelter can be adjusted by the degree of upward rotation of the buckle 1 around the top bearing 2 of the ladder body 3, and the stability of the overall structure is enhanced. When the buckle 1 is rotated downward through the top bearing 2 of the ladder body 3 to adhere to the ladder body 3, it is in the folding state. In the folding state, it is conducive to realizing the folding of the buckle 1 and the ladder body 3, reducing the volume of the overall device, and facilitating carrying and storing.

[0039] When in use, first find the stand column that can support the weight of the operator. The one side opening of the clamping piece of the buckle 1 is accurately clamped on the stand column, and the position of the buckle 1 is adjusted constantly during the clamping process to ensure that the buckle 1 is closely fitted with the stand column. After clamping, whether it is stable can be determined by gently shaking the ladder body 3 and observing the connection of the buckle 1.

[0040] After confirming that it is correct, the operator needs to step on the step 4, and at the same time, the body is kept balanced, and the hand holds the ladder body 3, so as to ensure stability. Then the device can be used to perform a series of high-altitude operations such as opening and closing air ports and maintaining equipment.

[0041] When the operation is completed, after the operator gets off the step 4 to the ground, the buckle 1 is separated from the stand column by gently shaking the ladder body 3 and observing the opening of the clamping piece of the buckle 1 and the position of the stand column. After the buckle 1 is separated from the stand column, the buckle 1 falls to adhere to the ladder body 3, realizing folding, and the overall device occupies small space, facilitating carrying and storing.

[0042] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
