Description

Technical Field

[0001] The invention relates to the technical field of crop insect prevention, and in particular to an insect prevention device for crop planting. Background Art

[0002] In the agricultural field, insect pests are a major problem in crop production. They can seriously harm the growth, development and yield of crops. For example, aphids will suck the juice of crops, causing the leaves to turn yellow, shrink or even wither; while borers will eat the leaves and fruits of crops, causing a double decline in crop yield and quality. Therefore, it is crucial to use insect repellent devices to prevent and reduce the impact of insect pests.

[0003] For example, a patent with a patent authorization publication number of CN221949074U and an announcement date of 2024-11-05 discloses a vegetable cultivation and insect prevention device for vegetable planting, including a planting mounting block, a planting groove is opened on the planting mounting block, semicircular blocks are symmetrically fixed on the planting mounting block, mounting components are arranged on the semicircular blocks, and insect attractant components are arranged between the semicircular blocks. The mounting components include an insect-proof net covering the semicircular blocks, and a plurality of fixed arc tubes are equidistantly fixed on the top surface of the insect-proof net, and matching fixed arc rods are inserted on the fixed arc tubes, and inverted L-shaped blocks are fixed on both ends of the fixed arc rods, and a fixed tube is fixed on the inverted L-shaped block located on one side between two adjacent inverted L-shaped blocks, and an insertion rod is fixed on the inverted L-shaped block located on the other side, and the insertion rod is slidably inserted in the fixed tube at the corresponding position. However, the above scheme still has certain shortcomings in actual use. For example, during use, since the insect-proof net is an integrated design, this may cause inconvenience in actual operation. When it is necessary to perform local operations on a part of the plants in the planting trough, it may be necessary to open the entire insect-proof net or a larger area of ​​the insect-proof net. This not only increases the complexity of the operation, but may also affect the insect-proof effect of other parts, which will reduce the effectiveness of the insect-proof net and make crops more vulnerable to pests.

[0004] Based on the above situation, the present invention proposes an insect-proof device for crop planting which is easy to operate and has a better insect-proof effect. Summary of the invention

DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0034] Embodiment 1: An insect-proof device for crop planting, such as Figure 1-Figure 6 As shown, it includes a first bracket 1, on which a side net 11 symmetrically distributed on the left and right is fixedly connected, on which four insect-proof nets 12 symmetrically distributed are fixedly connected, on which a second bracket 13 is fixedly connected on the top of the first bracket 1, on which four sliding frames 14 symmetrically distributed are slidably connected, and the movable ends of the four insect-proof nets 12 are fixedly connected to the adjacent sliding frames 14, and a double-axis motor 2 is installed in the middle of the second bracket 13, and the output shafts symmetrically distributed on the double-axis motor 2 are fixedly connected to screws 21 through couplings, and the two screws 21 are all threadedly connected with sliding members 22, the two sliding members 22 are slidably connected to the second bracket 13, the bottoms of the two sliding members 22 are fixedly connected with multi-section telescopic rods 23 distributed symmetrically on the left and right, the bottoms of the four multi-section telescopic rods 23 are all fixedly connected with cylinders 251, and first springs 24 are connected between the cylinders 251 and the adjacent sliding members 22, the four first springs 24 are all wound around the adjacent multi-section telescopic rods 23, and the four cylinders 251 are provided with limit assemblies for allowing the sliding frame 14 to be installed on the multi-section telescopic rods 23.

[0035] like Figure 6 As shown, the limit assembly includes a first rotating member 25, and four symmetrically distributed first rotating members 25 are all rotatably connected in the cylinder 251. The four first rotating members 25 are all slidably connected with a latch 26, and a second spring 27 is connected between the latch 26 and the adjacent first rotating member 25. The four second springs 27 are all wound around the adjacent latch 26. The sides of the sliding frames 14 that are close to each other are all provided with sockets, and the latch 26 and the adjacent sliding frames 14 are all snap-fitted.

[0036] like Figure 7 and Figure 8 As shown, it also includes a sealing mechanism for blocking the gap between the two sides of the insect-proof net 12 and the first bracket 1. The sealing mechanism is arranged on the first bracket 1, and the sealing mechanism includes a fixing rod 33. Eight symmetrically distributed fixing rods 33 are all fixedly connected to the upper side of the first bracket 1. A sealing member 32 is slidably connected between the two fixing rods 33 corresponding to each sliding frame 14. The four sealing members 32 are all arranged in an arc shape that fits the first bracket 1. A third spring 34 is connected between the sealing member 32 and the adjacent fixing rod 33. The eight third springs 34 are all wound around the adjacent fixing rod 33. A control component is provided between the sealing member 32 and the adjacent sliding frame 14.

[0037] like Figure 7As shown, the control assembly includes rollers 3, and the rollers 3 symmetrically distributed front and back are rotatably connected to the left and right sides of the first bracket 1. Pull ropes 31 are connected between the sliding frame 14 and the adjacent sealing member 32, and the four pull ropes 31 are wound around the adjacent rollers 3.

[0038] Initially, the insect-proof net 12 is in a folded state, the four sliding frames 14 are all located on the upper side of the first bracket 1, the multi-section telescopic rod 23 is in a contracted state, the first spring 24 is in a deformed state, and the four seals 32 are all located on the upper part of the fixed rod 33, and the seals 32 are not in contact with the first bracket 1. When the device is used, it is first placed in the planting area. When it is necessary to prevent insects from being applied to the crops in the planting area, all the insect-proof nets 12 need to be put down so that the pests cannot damage the crops. At this time, the dual-axis motor 2 can be controlled to drive the screw 21 to rotate, so that The driving slide 22 drives the multi-section telescopic rod 23 to move outward, and then drives the sliding frame 14 to slide outward through the cylinder 251, the first rotating member 25, and the pin 26, so that the insect-proof net 12 is unfolded on the first bracket 1, and cooperates with the side net 11 to cover the planting area. At the same time, the sliding frame 14 sliding outward pulls the sealing member 32 downward through the pull rope 31, so that the sealing member 32 moves downward to press the left and right sides of the insect-proof net 12, preventing pests from drilling into the planting area from the gap between the side of the insect-proof net 12 and the first bracket 1, and the third spring 34 will be deformed.

[0039] When it is necessary to perform local operations on a certain part of the plants in the planting trough, for example, to operate on the right front area, the latch 26 on the right front side can be pulled to the right to withdraw it from the right front sliding frame 14, and then the latch 26 can be turned downward by 90°, thereby driving the first rotating member 25 to turn downward by 90°, releasing the clamping connection between the multi-section telescopic rod 23 on the right front side and the right front sliding frame 14, and then the right front sliding frame 14 can be held and pushed upward, and the sliding frame 14 will drive the insect-proof net 12 on the right front side together Move up and close to open the right front area in the planting trough, the staff can operate this local area, and under the elastic force of the third spring 34 on the right front side, the seal 32 on the right front side will move upward to the initial position. When the operation of this local area is completed, the sliding frame 14 on the right front side is pulled down to its original position, and the pin 26 on the right front side is inserted back to its original position. The insect-proof net 12 in this area is unfolded again, and the seal 32 on the right front side also moves down to press on the insect-proof net 12 on the right front side.

[0040] Similarly, the same operation is performed in other areas. In summary, the insect-proof net 12 can be quickly unfolded and folded through the cooperation of the sliding frame 14, the screw 21, the sliding member 22, the multi-section telescopic rod 23, the first rotating member 25, and the latch 26. When local area operation is required, the insect-proof net 12 in the area can be folded by simply pulling out the latch 26 of the area, which provides great convenience for the staff. At the same time, the side edges of each insect-proof net 12 can be pressed tightly by the sliding frame 14, the pull rope 31, and the sealing member 32 to prevent pests from drilling into the gap between the insect-proof net 12 and the first bracket 1, thereby improving the insect-proof effect of the device.

[0041] Embodiment 2: Based on embodiment 1, Figure 9-11 As shown, it also includes a storage mechanism for rolling up the insect-proof net 12, the storage mechanism is arranged on the first bracket 1, and the storage mechanism includes a gear ring 4, the gear rings 4 symmetrically distributed along the second bracket 13 are all fixed to the middle part of the first bracket 1, the four sliding frames 14 are rotatably connected to the second rotating members 42, the four second rotating members 42 are all provided with bayonet holes, the four insect-proof nets 12 are all passed through the bayonet holes of the adjacent second rotating members 42, and the second rotating members 42 are fixed with gears 41 on the sides close to each other, and the gears 41 are meshed with the adjacent gear rings 4.

[0042] When the sliding frame 14 slides up and down, the sliding frame 14 will drive the second rotating member 42 and the gear 41 to slide up and down together. Since the gear 41 and the ring gear 4 are meshed with each other, the gear 41 will drive the second rotating member 42 to rotate, and the rotating second rotating member 42 will either reel in or release the insect-proof net 12. In summary, through the cooperation of the gear 41, the second rotating member 42, and the ring gear 4, the insect-proof net 12 can be rolled up neatly to avoid the situation where the retracted insect-proof net 12 droops due to gravity during local operations in the planting area, affecting the smooth progress of the work. Since the rolling process is orderly and controlled, the deformation of the insect-proof net 12 caused by improper retraction is also reduced, thereby extending its service life and improving the convenience and efficiency of operation.

[0043] like Fig.12 and Fig.13 As shown, it also includes a stabilizing mechanism for locking the sliding frame 14, which is arranged on the four sliding frames 14. The stabilizing mechanism includes a fixing member 5, and the four fixing members 5 are respectively fixed to the side of the sliding frame 14 away from each other. The four fixing members 5 are slidably connected with sliding rods 52, and fourth springs 53 are connected between the sliding rods 52 and the adjacent fixing members 5. The four fourth springs 53 are all wound around the adjacent sliding rods 52. The four fixing members 5 are all fixed with locking wheels 51, and the four sliding rods 52 are also fixed with locking wheels 51. The outer sides of the eight locking wheels 51 are in contact with the first bracket 1, and the eight locking wheels 51 are all made of rubber material that can increase friction.

[0044] When only a small part of the insect-proof net 12 needs to be opened, the sliding frame 14 can be pushed upward to the specified position, and the sliding frame 14 will drive the adjacent fixing member 5 to move upward, thereby driving the sliding rod 52 and the locking wheel 51 to move upward, and the locking wheel 51 will slide on the first bracket 1. Since there is a sufficiently large friction force between the locking wheel 51 and the first bracket 1, the two locking wheels 51 will be stuck on the first bracket 1, so that the sliding frame 14 can stay in this position stably, thereby realizing local operation of the insect-proof net 12. When the insect-proof net 12 needs to be closed, the sliding frame 14 is pulled downward, and the fixing member 5, the sliding rod 52, and the locking wheel 51 move downward and reset accordingly. In summary, through the cooperation of the locking wheel 51, the fixing member 5, the sliding rod 52 and the fourth spring 53 and the application of rubber material, the sliding frame 14 can be accurately controlled and stably stopped, thereby realizing local operation and resetting of the insect-proof net 12, and improving the accuracy and stability of the operation.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
