Description

Technical Field

[0001] This utility model relates to the field of agricultural planting equipment technology, specifically to an adjustable vegetable insect-proof net cover. Background Technology

[0002] Summer vegetable cultivation mainly involves planting crops that thrive in sunlight and high temperatures. However, this is accompanied by severe pest infestations, with flying insects being the most prevalent. Because flying insects possess strong migratory abilities, conventional control methods are ineffective. Even with targeted and scheduled insecticide extermination, it's impossible to prevent the invasion of new swarms. Therefore, in addition to spraying insecticides, insect-proof nets are typically installed above the vegetables to block flying insects. However, these nets also block sunlight from reaching the vegetables. Nets with dense mesh, designed to effectively intercept flying insects, severely restrict sunlight, resulting in insufficient light absorption and hindering vegetable growth. Therefore, an adjustable insect-proof net structure is needed, allowing for adjustments in its opening and closing to facilitate sunlight absorption when there is sufficient light, while providing protection against insects for the majority of the time. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an adjustable vegetable insect-proof net cover. It achieves the adjustment of unfolding or retracting the protective net during use by setting a shaft-driven support stepping and winding structure, and sets a corresponding linkage transmission structure to realize the drive control of the device in different usage scenarios.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] It includes a receiving roller and a protective net, wherein the protective net is wound around the receiving roller. It also includes:

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figure 1-4 As shown, the specific implementation adopts the following technical solution:

[0027] This specific embodiment includes a fixed plate 3, a support slide rail 4, and a support shaft 5. The fixed plates 3 are arranged in two sets, left and right symmetrically, and in two sets, front and back. There are two support slide rails 4, which are respectively set in the fixed plates 3 in the front and back sets. The left and right ends of the support slide rails 4 are respectively fixed on the fixed plates 3 on the left and right sides. The support shaft 5 is mounted on the support slide rails 4 on the front and back sides. The support wheels 6 are rotated on the front and back ends of the support shaft 5 through bearings. The support wheels 6 on the front and back sides are respectively mounted on the support slide rails 4 on the front and back sides. A collection roller 1 is sleeved and fixed on the support shaft 5. A protective net 2 is rolled on the collection roller 1.

[0028] Support sleeves 8 are movably fitted at both ends of the support shaft 5, and the support sleeves 8 are fixedly mounted on the end walls of the support wheel 6. A stepping gear 9 is fitted and fixed on the support sleeve 8. A limiting plate 7 is mounted above the support slide rail 4, and the left and right ends of the limiting plate 7 are fixedly mounted on the left and right fixing plates 3 respectively. A stepping rack 10 is fixedly mounted on the limiting plate 7. The upper side of the stepping gear 9 meshes with the stepping rack 10. A guide rod 11 is provided on the side of the support slide rail 4, and the left and right ends of the guide rod 11 are fixedly mounted on the left and right fixing plates 3 respectively. A mounting seat 12 is fitted on the guide rod 11. A drive shaft 13 is provided above the receiving roller 1, and the rear end of the drive shaft 13 is screwed onto the mounting seat 12 on the rear side through a bearing. The front and rear ends of the drive shaft 13 are respectively connected to the support sleeves 8 on the front and rear sides through a spur gear set.

[0029] Three couplers 16 are fixedly installed on the front mounting base 12 from top to bottom. The output shaft of the uppermost coupler 16 is connected to the front end of the transmission shaft 13 via a spline drive. The output shaft of the middle coupler 16 is connected to the front end of the support shaft 5 via a spline drive. A reversing shaft 15 is fixedly installed on the output shaft of the lowermost coupler via a spline drive. The reversing shaft 15 is connected to the support shaft 5 via a spur gear set drive. A dual-axis motor 14 is fixedly installed on the front mounting base 12. The upper shaft of the dual-axis motor 14 is connected to the input shaft of the uppermost coupler 16 via a bevel gear set drive. The lower shaft of the dual-axis motor 14 is connected to the output shafts of the two lower couplers 16 via a bevel gear set drive.

[0030] When using this device, the outer edge of the protective net 2 is fixed to the external structure located on one side of the support slide rail 4. When the protective net 2 rolled on the collecting roller 1 is unrolled, the coupler 16 connected to the drive shaft 13 is closed, and the other two couplers 16 are disconnected. The dual-axis motor 14 is driven to rotate the drive shaft 13 through the uppermost coupler 16. The drive shaft 13 drives the support sleeve 8 to rotate through the spur gear set. The support sleeve 8 drives the support wheel 6 and the stepping gear 9 to rotate. The support wheel 6 rolls and slides on the support slide rail 4, and the stepping gear 9 rolls and slides on the stepping rack 10. The stepping wheel drives the support shaft 5 to move, and the support shaft 5 drives the collecting roller 1 to move, while keeping the collecting roller 1 free to rotate, thus unfolding the protective net 2 on the collecting roller 1. When the unfolded protective net 2 is rolled back onto the collecting roller 1, the coupler 16 connected to the support shaft 5 is closed, and the other two couplers are disconnected, thus driving the dual-axis motor 14 to rotate. 4 drives the support shaft 5 to rotate, and the support shaft 5 drives the collecting roller 1 to rotate, thereby rolling up the unfolded protective net 2. When the support shaft 5 drives the collecting roller 1 to roll up the protective net 2, the support wheel 6 is pulled by the support shaft 5 to move on the support slide rail 4 as the flood control net is rolled up. As the support wheel 6 moves, it drives the stepping gear 9 to roll on the stepping rack 10. The two support sleeves 8 are transmitted through the transmission shaft 13, thereby maintaining the same speed of the two stepping gears 9, and thus realizing the synchronous movement of the two support wheels 6, that is, the synchronous movement of the front and rear ends of the support shaft 5. Alternatively, when the protective net 2 is fully unfolded and the net needs to be rolled up in the opposite spiral direction, the coupler 16 connected to the reversing shaft 15 is closed and the other two couplers 16 are disconnected. Thus, the dual-axis motor 14 drives the reversing shaft 15 to rotate, and the reversing shaft 15 drives the support shaft 5 to rotate, that is, realizing the reverse rotation of the support shaft 5.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1. This device is equipped with a support shaft 5 and support wheels 6 are installed at both ends of the support shaft 5. The support wheels 6 are supported by the support slide rail 4, which supports the winding roller 1 of the protective net 2, thereby realizing the adjustment of the unfolding and retraction of the protective net 2.

[0033] 2. This device is equipped with a transmission shaft 13 for the support wheel 6, and a stepping gear 9 that moves synchronously with the support wheel 6. The stepping gear 9 is mounted on a stepping rack 10, thereby maintaining the synchronous movement of the two support wheels 6, that is, maintaining the synchronous movement of the front and rear ends of the support shaft 5.

[0034] 3. In view of the requirements of the winding direction of the receiving roller 1 in winding up the protective net 2, this device is equipped with a reversing shaft 15 that drives the support shaft 5. Based on the dual-axis motor 14, couplers 16 are set for both the support shaft 5 and the reversing shaft 15 to connect with the output shaft of the dual-axis motor 14, so as to realize the controllable rotation of the support shaft 5 or the rotation of the reversing shaft 15, thereby realizing the control of the rotation direction of the support shaft 5.

[0035] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
