Description

Technical Field

[0001] This utility model relates to the field of crop planting technology, specifically a crop irrigation device for greenhouses. Background Technology

[0002] Crop cultivation is a complex and meticulous process involving knowledge and technology from multiple aspects. Greenhouse cultivation, which uses greenhouses constructed with materials such as plastic film and glass to grow crops, is a scientific agricultural cultivation method that provides plants with a relatively closed and controllable growth environment by constructing greenhouse structures.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: When crops are grown in greenhouses, irrigation mechanisms are set up inside the greenhouses. The positions of the spray pipes in traditional irrigation mechanisms are relatively fixed, and most of the spray pipes are connected by bolts and fixing frames. In practical applications, this not only makes it inconvenient to adjust the position of the spray pipes, but also makes it inconvenient to disassemble and reassemble them after the spray pipes are damaged. Therefore, in order to address the above problems, an irrigation device for crops in greenhouses is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The greenhouse crop irrigation device of this utility model includes two supports, a spray pipe and a support device. The bottom ends of the two supports are fixedly connected to fixed rods, and the spray pipe is located directly below the two fixed rods. The support device is set on the surface of the two fixed rods and the spray pipe. The support device includes a movable frame, which is sleeved on the surface of the two fixed rods. Two support columns are fixedly connected to both sides of the movable frame. Movable blocks are slidably connected to the surface of the support columns. Clamps are fixedly connected to the side walls of the two movable blocks on the same side. The clamps are sleeved on the surface of the spray pipe. Pushing the clamps causes the clamps to move the movable blocks. The movable blocks slide on the surface of the support columns. The clamps are sleeved on the surface of the spray pipe. By setting the movable frame, support columns, movable blocks and clamps, the position of the spray pipe can be fixed, and the position of the spray pipe can also be adjusted.

[0006] Preferably, the side wall of the movable block is fixedly connected to a connecting block, and the inner walls of the two adjacent connecting blocks and the inner wall of the movable frame are threadedly connected to a positioning pin. The positioning pin rotates to the inner walls of the two connecting blocks and the movable frame. By setting the positioning pin and the connecting block, the position of the movable block can be fixed.

[0007] Preferably, the movable frame is rotatably connected to two support wheels near the fixed rod. The two support wheels are located at the upper and lower ends of the fixed rod, respectively. The support wheels roll on the surface of the fixed rod. By setting the support wheels, the position of the movable frame on the surface of the fixed rod can be easily adjusted.

[0008] Preferably, support plates are fixedly connected to both sides of the movable frame, and a movable plate is fixedly connected to the surface of the clamp. The inner wall of the movable plate is slidably connected to the surface of the support plate, and the movable plate slides on the surface of the support plate. The arrangement of the support plate and the movable plate can support the clamp.

[0009] Preferably, the surfaces of the movable frame and the fixed rod are provided with a limiting device. The limiting device includes a placement block, the side wall of which is fixedly connected to the side wall of the movable frame. An insert block is slidably connected inside the placement block, and a pull block is fixedly connected to the side wall of the insert block. The insert block is inserted into the inner wall of the movable frame and the fixed rod. By setting the placement block, the insert block, and the pull block, the position of the movable frame on the surface of the fixed rod can be limited.

[0010] Preferably, a spring is fixedly connected to the side wall of the insertion block and the surface of the placement block. The spring drives the insertion block to slide. By setting the spring, the insertion block can be driven to slide, and the position of the insertion block can also be restricted.

[0011] Preferably, the surface of the fixing rod is provided with multiple insertion holes, and the insertion block is inserted into the inner wall of the insertion hole of the fixing rod. When the insertion block slides, the insertion block is inserted into the inner wall of the insertion hole, and the insertion hole is designed to accommodate the insertion block.

[0012] The advantages of this utility model are:

[0013] 1. When watering crops is required, this utility model involves fixing the support frame and greenhouse frame, then pushing the movable frame to rotate the support wheels. The support wheels roll on the surface of the fixed rod. After the movable frame moves to the appropriate position, the spray pipe is placed at the bottom of the movable frame. Then, the clamp is pushed to make the clamp slide the movable block. The movable block slides on the surface of the support column. When the movable block slides, it will drive the connecting block to slide. The clamp will clamp the surface of the spray pipe. When the clamp moves, it will also drive the movable plate to slide. The movable plate slides on the surface of the support plate. After the clamp wraps around the spray pipe, the positioning pin is rotated to the inner wall of the two connecting blocks and the movable frame. By setting the entire device, the spray pipe can be fixed, and the position of the spray pipe can be easily adjusted to meet the needs of different crops.

[0014] 2. When the position of the movable frame needs to be adjusted, the pull block is pulled to make the insert block slide. The insert block causes the spring to retract. When the insert block slides, it will slide on the surface of the placement block. After the movable frame moves to the appropriate position, the pull block spring is released to rebound. The spring drives the insert block to insert into the inner wall of the movable frame and the inner wall of the insertion hole of the fixing rod. By setting the entire device, the position of the movable frame can be restricted and the random movement of the movable frame can be reduced. Attached Figure Description

The support device 4 includes a movable frame 41, which is fitted onto the surfaces of the two fixed rods 2. Two support columns 42 are fixedly connected to both sides of the movable frame 41. Movable blocks 43 are slidably connected to the surfaces of the support columns 42, and clamps are fixedly connected to the side walls of the two movable blocks 43 on the same side. The frame 44 and the clamp 44 are fitted onto the surface of the nozzle 3. During operation, the movable frame 41 is pushed to slide on the surfaces of the two fixed rods 2. After the movable frame 41 slides to the appropriate position, the nozzle 3 is moved to the bottom of the movable frame 41. Then, the clamp 44 is pushed to drive the movable block 43 to slide. The movable block 43 slides on the surface of the support column 42. The clamp 44 is fitted onto the surface of the nozzle 3. By setting the movable frame 41, support column 42, movable block 43 and clamp 44, the position of the nozzle 3 can be fixed, and the position of the nozzle 3 can also be adjusted.

[0024] The side wall of the movable block 43 is fixedly connected to a connecting block 45. The inner walls of the two close connecting blocks 45 and the inner wall of the movable frame 41 are threadedly connected to a positioning pin 46. During operation, the movable block 43 drives the connecting blocks 45 to slide. After the connecting blocks 45 move to the appropriate position, the positioning pin 46 is rotated to the inner walls of the two connecting blocks 45 and the movable frame 41. By setting the positioning pin 46 and the connecting blocks 45, the position of the movable block 43 can be fixed.

[0025] Two support wheels 47 are rotatably connected to the surface of the movable frame 41 near the fixed rod 2. The two support wheels 47 are located at the upper and lower ends of the fixed rod 2, respectively. During operation, the movable frame 41 drives the support wheels 47 to roll, and the support wheels 47 roll on the surface of the fixed rod 2. By setting the support wheels 47, the position of the movable frame 41 on the surface of the fixed rod 2 can be easily adjusted.

[0026] Both sides of the movable frame 41 are fixedly connected to support plates 48, and the surface of the clamp 44 is fixedly connected to a movable plate 49. The inner wall of the movable plate 49 and the surface of the support plate 48 are slidably connected. During operation, the clamp 44 drives the movable plate 49 to slide, and the movable plate 49 slides on the surface of the support plate 48. The support plate 48 and the movable plate 49 can support the clamp 44.

[0027] The surfaces of the movable frame 41 and the fixed rod 2 are provided with limiting devices 5. The limiting device 5 includes a placement block 51. The side wall of the placement block 51 is fixedly connected to the side wall of the movable frame 41. An insert block 52 is slidably connected inside the placement block 51. A pull block 53 is fixedly connected to the side wall of the insert block 52. The insert block 52 is inserted into the inner wall of the movable frame 41 and the fixed rod 2. During operation, the pull block 53 is pushed to make the pull block 53 drive the insert block 52 to slide. The insert block 52 slides on the surface of the placement block 51 and inserts into the inner wall of the movable frame 41 and the fixed rod 2. By setting the placement block 51, the insert block 52 and the pull block 53, the position of the movable frame 41 on the surface of the fixed rod 2 can be limited.

[0028] A spring 54 is fixedly connected to the side wall of the insertion block 52 and the surface of the placement block 51. During operation, the insertion block 52 drives the spring 54 to contract. When using the insertion block 52, the spring 54 is released to rebound. The spring 54 drives the insertion block 52 to slide. By setting the spring 54, the insertion block 52 can be driven to slide, and the position of the insertion block 52 can also be restricted.

[0029] The surface of the fixing rod 2 has multiple insertion holes 55, and the insertion block 52 is inserted into the inner wall of the insertion hole 55 of the fixing rod 2. When working, the insertion block 52 is inserted into the inner wall of the insertion hole 55, and the insertion hole 55 is designed to accommodate the insertion block 52.

[0030] Working principle: When watering crops is required, the support frame 1 and the greenhouse frame are fixed. Then, the movable frame 41 is pushed, causing the support wheel 47 to rotate. The support wheel 47 rolls on the surface of the fixed rod 2. After the movable frame 41 moves to the appropriate position, the spray pipe 3 is placed at the bottom of the movable frame 41. Then, the clamp 44 is pushed, causing the movable block 43 to slide. The movable block 43 slides on the surface of the support column 42. When the movable block 43 slides, it will cause the connecting block 45 to slide. The clamp 44 will clamp the surface of the spray pipe 3. When the clamp 44 moves, it will also cause the movable plate 49 to slide. The movable plate 49 slides on the surface of the support plate 48. After the clamp 44 wraps around the spray pipe 3, the positioning pin 46 is rotated to the two connecting pins. The inner walls of the connecting block 45 and the movable frame 41 are designed to fix the nozzle 3 and allow for easy adjustment of its position to suit the needs of different crops. When the position of the movable frame 41 needs to be adjusted, the pull block 53 is pulled to slide the insert block 52. The insert block 52 causes the spring 54 to retract. As the insert block 52 slides, it will slide on the surface of the placing block 51. After the movable frame 41 moves to the appropriate position, the pull block 53 and the spring 54 are released to rebound. The spring 54 drives the insert block 52 to insert into the inner wall of the movable frame 41 and the inner wall of the insertion hole 55 of the fixing rod 2. By designing the entire device, the position of the movable frame 41 can be restricted, reducing the possibility of the movable frame 41 moving randomly.
