Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0046] Examples, such as Figures 1 to 12 As shown, the present invention provides a technical solution: a vine-dropping device with controllable vine-dropping height for greenhouse cucumbers and a method for using the device, comprising a support frame 1, the support frame 1 is made of high-strength metal material, has good stability and durability, a driving mechanism 2 is installed at the top of the support frame 1 and near the right side, the driving mechanism 2 is used to control the height of the vine-dropping, a plurality of vine-dropping mechanisms 3 are installed horizontally in the middle of the support frame 1, the vine-dropping mechanisms 3 are used to receive the vines of the cucumber plant, a control system 4 is installed at the right side of the front end of the support frame 1 and near the bottom, a fixed base 5 is installed at the bottom of the support frame 1 and on both the left and right sides, and the fixed base 5 is used to stabilize the device;

[0047] like Figure 7 and Figure 8As shown, the vine-dropping mechanism 3 includes a rope 31, and the rope 31 as a whole is composed of two rope bodies spirally wound. A vine-dropping body 32 is installed at both ends of the rope 31. The rope 31 is horizontally installed between the two legs 13 through the vine-dropping body 32. The vine-dropping body 32 slides vertically on the legs 13 through the slide groove 131. A forked pipe frame 33 is installed on the top of the vine-dropping body 32. The forked pipe frame 33 is used to separately guide and rewind the two rope bodies of the rope 31. In this way, the tension of the rope 31 as a whole between the two vine-dropping bodies 32 is increased, and a pre-tightening force is applied to the rope 31 itself. , so that the rope 31 can bear the climbing and pressure of the vines of the cucumber plant, and will not be directly loosened by the vines, thereby ensuring that the rope 31 guides and controls the vines at a specified height; the end of the vine-falling body 32 away from the rope 31 is connected to the angle rod frame 34, and the end of the angle rod frame 34 away from the vine-falling body 32 is installed with a roller 35, and the roller 35 is rotatably installed with the vine-falling body 32 through the angle rod frame 34. The roller 35 is used to reel in excess rope 31, and can reel in excess rope 31 that is guided out from the inside of the forked pipe frame 33 and spirally wound again, thereby avoiding messy placement of the ends of the rope 31.

[0048] like Figure 1 and Figure 6 As shown, the support frame 1 includes a first bracket 11, a second bracket 12 is installed on the front of the first bracket 11, and the second bracket 12 has the same structure as the first bracket 11, and the left and right ends of the first bracket 11 are connected with supporting legs 13, that is, the first bracket 11 and the second bracket 12 and the supporting legs 13 connected to the ends of the two together constitute the support frame 1, and a sliding groove 131 is vertically opened in the middle of the front of the supporting leg 13.

[0049] The driving mechanism 2 includes a frame 21 bolted to the top right side of the support frame 1, and a motor 22 is installed on the inner side of the frame 21 to provide power for the equipment. A horizontal transmission shaft 23 is installed between the first bracket 11 and the second bracket 12 and close to the vine-dropping mechanism 3. The rotational motion of the motor 22 is transmitted to the vine-dropping body 32 of the vine-dropping mechanism 3 through the horizontal transmission shaft 23. A bevel gear transmission module 25 is installed on the surface of the horizontal transmission shaft 23 and at the left and right ends thereof. A vertical transmission shaft 24 is installed in the slide groove 131 opened in the middle of the front of the leg 13. The surface of the vertical transmission shaft 24 is provided with a thread, and the vertical transmission shaft 24 is installed with the horizontal transmission shaft 23 through the bevel gear transmission module 25.

[0050] A reducer 26 is installed on the inner side of the frame 21 and close to the horizontal transmission shaft 23, which is used to reduce the output speed of the motor 22 and increase the output torque to ensure the stability and accuracy of the vine-dropping operation. The input end of the reducer 26 is connected to the output end of the motor 22, and the output end of the reducer 26 is connected to the right end of the horizontal transmission shaft 23. A sleeve 27 is mounted on the surface of the vertical transmission shaft 24 and close to one end of the horizontal transmission shaft 23. The sleeve 27 is used to position and guide the vertical transmission shaft 24 in the vertical direction. The sleeve 27 is inserted into the support leg 13, and the end of the vertical transmission shaft 24 away from the horizontal transmission shaft 23 is rotatably installed with the support leg 13. The vertical transmission shaft 24 is rotatably installed with the support leg 13 through the bevel gear transmission module 25 on the horizontal transmission shaft 23 and the reducer 26 connected to the output end of the motor 22.

[0051] like Figure 7 and Fig.11 As shown, a wire clamp 36 is installed at one end of the bifurcated pipe frame 33 close to the angle rod frame 34, which is used to lock the rope 31 after being separated and guided by the bifurcated pipe frame 33 and then spirally wound together to prevent the rope 31 from loosening. A ring sleeve 37 is installed on the inner side of the falling vine body 32. A double-headed electromagnetic rod 38 is installed in a centrally symmetrical shape on the inner wall of the ring sleeve 37. An outer ring body 39 is installed in the ring sleeve 37. The ring sleeve 37 is used to provide an installation platform for the installation of the double-headed electromagnetic rod 38 on the inner side of the falling vine body 32, and at the same time, the outer ring body 39 is covered on its inner side. The outer ring body 39 is composed of two semicircular tubes. It is made of elastic metal material and can be squeezed and deformed by the double-headed electromagnetic rod 38. An internal threaded part 310 is installed in the outer ring body 39 in a centrally symmetrical shape and can be threadedly installed with the vertical transmission shaft 24. The internal threaded part 310 is limitedly installed in the outer ring body 39 by the ring sleeve 37. The inner diameter of the internal threaded part 310 is larger than the diameter of the vertical transmission shaft 24, and the outer diameter of the internal threaded part 310 is smaller than the inner diameter of the outer ring body 39. Through the above structural design, the internal threaded part 310 can be flexibly pushed on the inner side of the outer ring body 39, which facilitates the approach and distance between the internal threaded part 310 and the vertical transmission shaft 24.

[0052] The two ends of the double-headed electromagnetic rod 38 are equipped with locking tongues 381, and the ring sleeve 37 can be used to provide a deformable space for the outer ring body 39 to be pushed by the locking tongue 381 on the double-headed electromagnetic rod 38 on the inner side of the ring sleeve 37. The locking tongue 381 and the double-headed electromagnetic rod 38 are telescopically installed, and the falling vine body 32 is positioned and locked with the support leg 13 through the cooperation of the double-headed electromagnetic rod 38 and the locking tongue 381. The internal threaded part 310 pushes the outer ring body 39 and is threadedly installed on the vertical transmission shaft 24 through the locking tongue 381 on the double-headed electromagnetic rod 38. That is to say, when the internal threaded part 310 is pushed by the locking tongue 381 on the double-headed electromagnetic rod 38 to contact the thread of the vertical transmission shaft 24, it can drive the falling vine body 32 to move up and down along the slide groove 131 under the activation of the motor 22, so that the rope 31 can adjust the height of the vines up and down by itself under the transmission action of the motor 22; through the design of the above structure, when the height of the vines needs to be regulated, the double-headed electromagnetic rod 38 can be activated to move away from the slide groove The two locking tongues 381 of 131 extend out and push the outer ring body 39 to be concave toward its center, thereby pushing the internal threaded part 310 on the inner side of the outer ring body 39 toward the vertical transmission shaft 24, so that the falling vine body 32 is now threadedly installed with the vertical transmission shaft 24 through the two locking tongues 381 on the double-headed electromagnetic rod 38. The motor 22 can then be enabled to transmit the transmission force of the motor 22 to the falling vine body 32, so that the falling vine body 32 can be adjusted up and down in the vertical direction along the vertical guiding direction of the support leg 13 on the inner side of the slide groove 131, following the specific steering of the vertical transmission shaft 24 driven by the motor 22, thereby realizing self-adjustment of the vine height. Once adjusted to the preset height, the locking tongues 381 on the double-headed electromagnetic rod 38 can be called back to the initial state again, that is, the falling vine body 32 can be repositioned and locked on the inner side of the slide groove 131 through another pair of locking tongues 381, to ensure that the vine grows within the preset height.

[0053] When the height of the vines on the rope 31 does not need to be adjusted, the locking tongue 381 on the double-headed electromagnetic rod 38 can be activated, that is, the locking tongue 381 on the double-headed electromagnetic rod 38 away from the end of the internal threaded part 310 is activated to extend, and the locking tongue 381 close to the end of the internal threaded part 310 can be retracted; by using the two locking tongues 381 installed in the ring sleeve 37 in a centrally symmetrical shape, they extend and contact the middle of the slide groove 131 opened in the middle of the support leg 13, and the locking tongue 381 can be extended from the surface of the vine falling body 32 to self-lock the position of the vine falling body 32 inside the slide groove 131, and at the same time, the tight threaded installation state of the internal threaded part 310 and the vertical transmission shaft 24 is released, so that the vines on the rope 31 between the two vine falling bodies 32 are temporarily separated from the regulation of the motor 22, thereby realizing the positioning and locking of the vine height on the rope 31.

[0054] The motor 22 drives the rope 31 between the two vine-falling bodies 32 to rise and fall through the horizontal transmission shaft 23, the vertical transmission shaft 24 and the bevel gear transmission module 25, wherein the motor 22 is a DC motor or a stepping motor, which can accurately control the rotation speed to achieve accurate control of the vine-falling height, and the reducer 26 is used to slow down the rotation speed of the motor output and increase the torque to ensure the smooth lifting and lowering of the rope 31; the drum 35 is a cylindrical structure, and its surface is provided with an anti-slip texture to ensure that the rope 31 will not slip or shift during the winding and locking process, thereby ensuring the smooth falling of the cucumber vines. The rope 31 is made of high-strength fiber material, has the characteristics of wear resistance and aging resistance, and can be used for a long time without affecting the operating performance of the equipment.

[0055] The control system 4 includes a controller 41, which is used to adjust the operating state of the vine-dropping mechanism 3. The controller 41 is bolted to the leg 13 at the right end of the second bracket 12, and the controller 41 is installed at a position close to the fixed base 5 through the leg 13. The bottom of the support frame 1 is installed with a height sensor 42 in a linear array. The height sensor 42 is used to detect the height of the cucumber plant in real time and transmit the data to the controller 41. The controller 41 is used to control the operation of the driving mechanism 2 according to a preset height. The height sensor 42 is a laser sensor or an ultrasonic sensor, which can measure the height of the cucumber plant with high precision and automatically adjust the operating state of the vine-dropping mechanism 3 through the controller 41.

[0056] The controller 41 in the control system 4 includes a microprocessor and a storage unit, which are used to process the data transmitted by the height sensor 42, and control the start, stop and speed adjustment of the motor 22 according to a preset program. It is also used to control the extension and retraction state of the locking tongue 381 on the double-headed electromagnetic rod 38. An operation interface is installed on the surface of the controller 41 for setting the target height and operation mode of the cucumber vine falling. The operation interface is communicated with the controller 41 and can display the current vine falling state in real time. Through the control of the motor 22 and the double-headed electromagnetic rod 38 by the control system 4, the vines placed on each vine falling mechanism 3 can be separated from the vines at other heights. Through the flexible conversion of the locking tongue 381 on the double-headed electromagnetic rod 38 in the horizontal position, the vines at different heights can be adjusted individually, and the vines at different heights can be adjusted synchronously.

[0057] Through the coordinated use of height sensors and control systems, the equipment can monitor the height of cucumber plants in real time, and automatically adjust the vine dropping according to the set target height to ensure uniform growth of the cucumber plants. The equipment's height adjustment, vine dropping operation and monitoring can all be automated, greatly reducing manual labor intensity and improving the efficiency of greenhouse management, making it particularly suitable for use in large-scale planting environments.

[0058] The vine-dropping mechanism 3 can be raised and lowered within the effective support height range of the support frame, so that the equipment can adapt to the growth height of cucumber plants in different greenhouses, has good versatility, and is suitable for cucumber plants at different growth stages.

[0059] The driving mechanism uses a combination of high-efficiency motors and reducers, and the gear meshing transmission between the horizontal transmission shaft, vertical transmission shaft and bevel gear transmission module and the threaded guide structure ensure the stability and reliability of the equipment operation. At the same time, the anti-slip design of the equipment and the use of high-strength materials improve the durability of the equipment and enable long-term stable operation.

[0060] The design of the equipment takes the protection of cucumber plants into consideration. The vine-dropping process is smooth, and the horizontal design of the rope facilitates the synchronous adjustment of multiple vines of the same growth on the same horizontal line. It not only saves a lot of manpower, but also avoids the hidden danger of plant injury caused by binding in traditional vine-dropping operations, avoids mechanical damage caused by manual operation, and ensures the healthy growth of cucumber plants.

[0061] The present invention provides a vine-removing device for greenhouse cucumbers which is highly controllable, automated in operation and widely applicable. Through the combination of machinery and intelligent control, the management level of cucumber planting is significantly improved, and reliable technical support is provided for efficient agriculture.

[0062] Before use, the equipment is first installed and debugged, and the support frame 1 is firmly installed in a suitable position in the greenhouse in a north-south direction to ensure that the support frame 1 can cover all cucumber plants that need to be vine-dropped; then the equipment is connected to the power supply to ensure that the motor 22 and the control system 4 are powered on, and the operating status of each component is checked to ensure that the equipment is working normally; then, according to the current plant height of the cucumber plant, the control system 4 activates the motor 22 to drive the rope 31 between the two vine-dropping bodies 32 to adjust the horizontal height of the rope 31 to the same position as the plant height under the threaded rotation adjustment of the vertical transmission shaft 24, so that the vines at the top of the cucumber plant are placed on the rope 31;

[0063] Then set the vine dropping parameters, start the device through the operation interface, and enter the operation setting mode; according to the growth stage of the cucumber plant, enter the target vine dropping height through the operation interface; you can manually enter a specific height value, or select a preset vine dropping mode such as fixed vine dropping mode, automatic height adjustment mode according to growth stage, etc.; then select the vine dropping operation mode: users can choose the automatic mode, where the system automatically controls the vine dropping according to the height measured by the height sensor, or the manual mode, where users can control the vine dropping process in real time through the operation interface;
