[0002] Currently, agricultural greenhouses are frame-and-film structures with excellent heat insulation properties. They effectively control environmental conditions for crop growth, such as temperature, humidity, and light, thereby enabling off-season planting and high-yield, high-quality crops. During the construction of agricultural greenhouses, the arched supports are key structural components supporting the greenhouse film, and their splicing quality directly affects the overall stability and lifespan of the greenhouse.

[0003] However, when connecting existing agricultural greenhouse arches, most of them are fixed with bolts after splicing. However, since the arches need to be bent at a certain angle, they cannot be easily bent and connected due to their elasticity during splicing. When relying on manual connection, the accuracy is poor, and the arches may fail to be splice due to their rebound.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides an arch splicing device to solve the problem that in the current agricultural greenhouse arch splicing, the connection is mostly made by bolting after splicing. However, because the arch needs to be bent at a certain angle, the arch cannot be easily bent and connected due to its elastic return during splicing. When relying on manual connection, the accuracy is poor, and the arch splicing will fail due to the rebound of the arch. Utility Model Content

[0005] This utility model proposes an arch splicing device, which solves the problem that existing agricultural greenhouse arch splices are mostly connected by bolts after splicing. However, because the arches need to be bent at a certain angle, the elasticity of the arches during splicing makes it difficult to bend and connect them easily. Manual splicing is also inaccurate and may fail due to the rebound of the arches.

[0006] The technical solution of this utility model is implemented as follows: an arch rod splicing device includes: a guide rail mechanism, the guide rail mechanism having a transverse groove inside, a moving mechanism being slidably connected inside the transverse groove, a side plate assembly being fixedly connected to the top surface of the moving mechanism, and a longitudinal groove being opened inside the side plate assembly.

[0007] The longitudinal groove in the side plate assembly is a guide groove, and the top of the moving mechanism has a recess. A spring rod is fixedly connected inside the recess. The main body of the spring rod is a telescopic rod structure with a spring, and a bracket assembly is fixedly connected to the top of the spring rod. The top of the bracket assembly has an arc-shaped groove.

[0008] In a preferred embodiment, two slider assemblies are fixedly connected to each other on the outer side of the moving mechanism. The slider assemblies are structures that protrude from the moving mechanism, and the moving mechanism is slidably connected to the guide rail mechanism through the slider assemblies.

[0009] In a preferred embodiment, a grip assembly is fixedly connected to the bottom surface of the guide rail mechanism, and a servo motor A is fixedly connected to the right side of the grip assembly. An output shaft is provided on the left side of the servo motor A, and a transmission screw is installed on the output shaft.

[0010] In a preferred embodiment, both of the moving mechanisms have screw holes that match the transmission screws inside, and the screw holes in the two moving mechanisms are oriented in opposite directions. A lifting push rod is fixedly connected to the top surface of the moving mechanism.

[0011] In a preferred embodiment, the lifting push rod is arranged longitudinally, and there are two lifting push rods in total. The two lifting push rods are fixedly connected to the top surfaces of the two moving mechanisms in opposite directions. Electromagnets are fixedly connected inside the two lifting push rods, and the limit frame is connected by the attraction of the electromagnets.

[0012] In a preferred embodiment, the main body of the limiting frame is a U-shaped structure with a one-way opening at the bottom, and inner guide blocks are fixedly connected to the inner sides of the two longitudinal components in the limiting frame.

[0013] In a preferred embodiment, the inner guide block is slidably connected in the guide groove, and a servo motor B is fixedly connected to the outer side of the limiting frame. A drive wheel is installed on the output shaft of the servo motor B, and a first arch rod and a second arch rod are respectively placed above the two bracket assemblies. The drive wheel is used for friction transmission to bring the first arch rod and the second arch rod closer together.

[0014] After using the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the servo motor A drives the transmission screw to move the moving mechanism, which realizes the precise adjustment of the lateral distance of the arch rod. This avoids the distance deviation caused by uneven force during manual adjustment and solves the problem of poor accuracy in manual docking. At the same time, the limiting frame can stably limit the arch rod under the action of the lifting push rod. With the friction transmission of the drive wheel, it effectively restricts the elastic reset of the arch rod, ensuring that the arch rod can be easily bent and docked, and overcoming the defect of splicing failure caused by the springback of the arch rod.

[0016] 2. In this utility model, the synergistic effect of the mechanical structure replaces the traditional manual splicing operation, which not only improves the efficiency of arch splicing, but also ensures the stability of splicing quality through the precise cooperation of each component.

Detailed Implementation

[0025] 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.

[0026] like Figures 1-6 As shown, an arch rod splicing device includes: a guide rail mechanism 1, the guide rail mechanism 1 has a transverse groove inside, a moving mechanism 2 is slidably connected inside the transverse groove, a side plate assembly 2011 is fixedly connected to the top surface of the moving mechanism 2, and a longitudinal groove is opened inside the side plate assembly 2011.

[0027] The longitudinal groove in the side plate assembly 2011 is a guide groove 2012, and the top of the moving mechanism 2 is provided with a groove. A spring rod 2013 is fixedly connected inside the groove. The main body of the spring rod 2013 is a telescopic rod structure with a spring, and the top of the spring rod 2013 is fixedly connected with a bracket assembly 2014. The top of the bracket assembly 2014 is provided with an arc-shaped groove.

[0028] Two slider assemblies 201 are fixedly connected to the outer side of the moving mechanism 2 in opposite directions. The slider assembly 201 is a structure that protrudes from the moving mechanism 2, and the moving mechanism 2 is slidably connected to the guide rail mechanism 1 through the slider assembly 201. A grip assembly 101 is fixedly connected to the bottom surface of the guide rail mechanism 1, and a servo motor A1011 is fixedly connected to the right side of the grip assembly 101. An output shaft is provided on the left side of the servo motor A1011, and a transmission screw 1012 is installed on the output shaft.

[0029] Both moving mechanisms 2 have screw holes inside that match the transmission screw 1012, and the screw holes in the two moving mechanisms 2 are oriented in opposite directions. A lifting push rod 3 is fixedly connected to the top surface of the moving mechanism 2. The lifting push rod 3 is arranged longitudinally, and there are two lifting push rods 3. The two lifting push rods 3 are fixedly connected to the top surface of the two moving mechanisms 2 in opposite directions. An electromagnet is fixedly connected inside the two lifting push rods 3, and the limit frame 301 is connected by the electromagnet adsorption.

[0030] The main body of the limiting frame 301 is a U-shaped structure with a one-way opening at the bottom. The inner sides of the two longitudinal components in the limiting frame 301 are fixedly connected to the inner guide blocks 3011, which are slidably connected in the guide groove 2012. The outer side of the limiting frame 301 is fixedly connected to the servo motor B3012. The output shaft of the servo motor B3012 is equipped with a drive wheel 3013. The first arch rod 3014 and the second arch rod 3015 are respectively placed above the two bracket assemblies 2014. The drive wheel 3013 is used for friction transmission to make the first arch rod 3014 and the second arch rod 3015 close to each other.

[0031] In use, firstly, the first arch rod 3014 and the second arch rod 3015 are placed in the arc-shaped grooves at the top of the two bracket assemblies 2014 respectively. Under the support of the spring rod 2013, the bracket assembly 2014 can be adjusted up and down according to the weight of the arch rod to ensure that the arch rod is placed stably.

[0032] Then, the servo motor A1011 is started, and its output shaft drives the transmission screw 1012 to rotate. Since the screw holes inside the two moving mechanisms 2 match the transmission screw 1012 and the screw hole directions are opposite, the rotation of the transmission screw 1012 will cause the two moving mechanisms 2 to slide relatively closer or further apart in the transverse groove of the guide rail mechanism 1 through the slider assembly 201, thereby adjusting the transverse distance between the two arch rods.

[0033] According to the bending requirements of the arch, the lifting push rod 3 is controlled to extend and retract longitudinally. The lifting push rod 3 drives the limiting frame 301 to move up and down. The inner guide block 3011 on the inner side of the limiting frame 301 slides in the guide groove 2012 of the side plate assembly 2011 to ensure the stability of the movement of the limiting frame 301 until the limiting frame 301 is adjusted to a suitable height to limit the arch.

[0034] Then, when the two arch rods are close to a certain distance, the servo motor B3012 is started, and its output shaft drives the drive wheel 3013 to rotate. The drive wheel 3013 contacts the first arch rod 3014 and the second arch rod 3015 and generates friction. Under the action of friction, the first arch rod 3014 and the second arch rod 3015 move towards each other along the arc groove of the bracket assembly 2014. At the same time, under the limiting action of the limiting frame 301, the arch rods are bent to the required angle, and finally the splicing is completed. After the splicing is completed, the assembly is completed by passing the bolts through the screw holes in the first arch rod 3014 and the second arch rod 3015. After the assembly is completed, the power to the lifting push rod 3 is turned off, and the limiting frame 301 is no longer limited. At this time, the limiting frame 301 can be removed from the lifting push rod 3.
