Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water and fertilizer spraying devices, and in particular to a water and fertilizer spraying device for vegetable seedling cultivation that is easy to use in greenhouses. Background Technology
[0002] When fertilizing vegetable seedlings in seedling greenhouses, water-based fertilizer is often used. The fertilization process is as follows: First, place an appropriate amount of fertilizer in an empty bucket, then add clean water to the empty bucket and stir well to mix the fertilizer and water evenly to form water-based fertilizer; then use a water pump to extract the water-based fertilizer. The water pump outlet is connected to a long hose with a nozzle at the end of the hose. The water-based fertilizer is sprayed onto different seedling beds by manually holding the nozzle.
[0003] Because the hose is quite long, it is difficult to drag. The limited length of the hose necessitates constantly moving the bucket to fertilize different seedbeds, further increasing the workload for staff. When fertilizing, staff walk along the aisle while simultaneously fertilizing the seedbeds on both sides. Moving the nozzle from one seedbed to the other causes some water and fertilizer to spill onto the aisle, making it slippery and hindering staff movement. This also results in some waste of water and fertilizer, increasing fertilization costs. Utility Model Content
[0004] To solve or partially solve the problems existing in related technologies, this utility model provides a vegetable seedling water and fertilizer spraying device that is easy to use in greenhouses, aiming to reduce the labor intensity of workers when fertilizing and avoid water and fertilizer waste.
[0005] The above-mentioned vegetable seedling water and fertilizer spraying device, which is easy to use in greenhouses, includes a spraying tank, a support frame, a water pump, a semi-circular pipe, a three-way pipe, and a spray nozzle;
[0006] The top of the application tank is equipped with a support frame, and a water pump is mounted on the support frame. The water pump has a water inlet pipe, and the free end of the water inlet pipe is inserted into the bottom of the application tank.
[0007] One end of the semicircular tube is hinged to the support frame, allowing the semicircular tube to rotate horizontally. There are two semicircular tubes, located on both sides of the support frame, and the semicircular tubes are provided with first slots evenly spaced along their length.
[0008] At least two T-joints are placed inside the semi-circular tube, wherein the horizontal section of the T-joint is placed inside the semi-circular tube, and the vertical section of the T-joint passes through the semi-circular tube from the first slot. Adjacent T-joints are connected by a flexible hose. A nozzle is provided at the lower end of the vertical section of the T-joint.
[0009] The outlet of the water pump is connected to one of the three-way pipes located at the end via a flexible hose, and the other three-way pipe located at the end is replaced with a right-angle elbow.
[0010] In some designs, a valve is provided on the connecting pipe between the water pump and the tee pipe.
[0011] In some designs, the outlet of the water pump is equipped with an overflow valve.
[0012] In some solutions, an extension tube is also included, the extension tube having a semi-circular cross-section, second slots spaced at intervals along its length, and a T-shaped locking block at the bottom of one end of the extension tube.
[0013] In some designs, a pressure plate is provided above the semicircular tube.
[0014] The technical solution provided by this utility model can include the following beneficial effects:
[0015] When applying fertilizer, simply push the application bucket along the aisle, allowing the semi-circular tube to pass over the seedling trays on both sides of the aisle. The nozzles on the semi-circular tube will then spray water and fertilizer onto the seedling trays, effectively reducing the labor intensity of the staff. Almost all the water and fertilizer are sprayed onto the seedling trays, effectively reducing the waste of water and fertilizer.
[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.
[0029] like Figures 1-3 As shown, this application provides a vegetable seedling water and fertilizer spraying device that is easy to use in greenhouses, including a spraying tank 1, a support frame 2, a water pump 3, a semi-circular pipe 4, a three-way pipe 5, and a nozzle 6.
[0030] The application tank 1 is a garbage can with wheels 101, which is easy to obtain, has high structural strength, and comes with a handle for easy movement. The top of the application tank 1 is equipped with a support frame 2, which consists of two I-shaped frames and a connecting rod. During installation, the two I-shaped frames are placed on the top two sides of the garbage can. A first through hole is opened on the bottom crossbar of the I-shaped frame, and a second through hole matching the position of the first through hole is opened on the top side of the garbage can. The connecting bolt passes through the first through hole and the second through hole from top to bottom and is connected to the nut. After the nut is tightened, the support frame 2 can be firmly installed on the garbage can.
[0031] The support frame 2 is equipped with a water pump 3, which can be an electric water pump 3, a gasoline water pump 3, or a diesel water pump 3. The water inlet end of the water pump 3 is equipped with a water pump pipe 301, and the free end of the water pump pipe 301 is inserted into the bottom of the application tank 1 so that the water pump 3 can completely extract the water and fertilizer from the application tank 1.
[0032] One end of the semicircular tube 4 is hinged to the support frame 2, so that the semicircular tube 4 can rotate horizontally. The groove of the semicircular tube 4 faces upward. There are two semicircular tubes 4, which are located on both sides of the support frame 2 respectively. The semicircular tube 4 is provided with a first slot 401 evenly spaced along its length direction. The first slot 401 extends downward from the top of one side of the semicircular tube 4 to its bottom.
[0033] At least two T-pipes 5 are placed inside the semicircular tube 4. The horizontal section of the T-pipe 5 is placed inside the semicircular tube 4, and the vertical section of the T-pipe 5 passes through the semicircular tube 4 from the first slot 401 and extends downward. Adjacent T-pipes 5 are connected by a flexible hose. A nozzle 6 is provided at the lower end of the vertical section of the T-pipe 5. The outer diameter of the vertical section of the T-pipe 5 matches the width of the slot 401. Since the outer diameter of the connecting end of the nozzle 6 is larger than the diameter of the vertical section of the T-pipe 5, after the nozzle 6 is installed on the T-pipe 5, a step is formed. The step and the horizontal section of the T-pipe 5 are located on the inner and outer sides of the semicircular tube 4, respectively, thereby clamping the semicircular tube 4 and fixing the position of the T-pipe 5 inside the semicircular tube 4. The outlet end of the water pump 301 is connected to one of the T-pipes 5 located at the end through a flexible hose, and the other T-pipe 5 located at the end is replaced by a right-angle elbow.
[0034] When using it, you can determine the spraying range of the selected nozzle 6 according to its specifications, and combine it with the amount of water and fertilizer to be sprayed to determine the distance between the two nozzles 6. Then adjust the distance between the two adjacent three-way pipes 5 so that the distance between the nozzles 6 meets the usage requirements.
[0035] During fertilization, the two semi-circular pipes 4 are rotated to extend to both sides, pushing the application tank 1 along the aisle. The two semi-circular pipes 4 pass over the seedling trays on both sides of the aisle. During this process, the water pump 3 works to extract the water and fertilizer from the application tank 1 and pump it to the nozzle 6 for spraying. This allows for simultaneous fertilization of the seedling trays on both sides of the aisle. Compared to dragging the fertilization pipes while fertilizing, this method effectively reduces the labor intensity of the workers. Moreover, the water and fertilizer can be sprayed onto the seedling trays, effectively reducing waste and thus lowering fertilization costs.
[0036] If the greenhouse pillars obstruct the fertilization process, the semicircular tube 4 can be rotated to bypass the obstacle, effectively ensuring the smooth progress of the fertilization process.
[0037] In some specific implementations, such as Figure 8As shown, a valve 7 is provided on the connecting pipe between the water pump 3 and the three-way pipe 5. Specifically, the water outlet of the water pump 3 is connected to the three-way pipe 5 on the two semi-circular pipes 4 through two flexible hoses. A valve 7 is also provided on each of the connected flexible hoses. This makes it easy for the staff to control the operation of only one side of the nozzle 6, so that the device can be used in greenhouses with an odd number of rows of seedling trays.
[0038] When fertilizing only the seedling trays near the inner wall of the greenhouse, the valve 7 away from the inner wall of the greenhouse can be closed, and then the semi-circular tube 4 can be rotated to fold it up, so that it can extend in the direction of travel or to the other side of the direction of travel. In this way, fertilization can be carried out on only one side of the seedling trays, which is more convenient to use.
[0039] In some specific implementations, such as Figure 8 As shown, the water pump pipe 301 is equipped with a filter 8, which effectively filters out incompletely dissolved fertilizer or impurities in the water and fertilizer, thereby avoiding the technical problem of water pump blockage.
[0040] In some specific implementations, such as Figure 8 As shown, the water pump 3 is equipped with an overflow valve 9 at its outlet. Specifically, the P port of the overflow valve 9 is connected to the outlet of the water pump 3, and the T port of the overflow valve 9 is directly opposite the bottom of the application tank 1. In this way, when the pressure at the outlet of the water pump 3 is too high, the water and fertilizer can flow back into the application tank 1 through the overflow valve 9, effectively avoiding the technical problem of the water pump being damaged due to excessive load when the pipe is blocked or the valve 7 is closed. At the same time, when changing passages, only the valve 7 can be closed without stopping the water pump, reducing the number of times the water pump is started and stopped, and the water pump is less likely to be damaged.
[0041] In some specific implementations, such as Figure 6 and Figure 7 As shown, the device also includes an extension tube 10 with a semi-circular cross-section. Second slots 1001 are spaced apart along the length of the extension tube 10. A T-shaped locking block 1002 is provided at the bottom of one end of the extension tube 10. When the length of the semi-circular tube 4 is insufficient, one end of the extension tube 10 can be placed on the plate tube, and the locking block 1002 can be inserted into the first slot 401, thereby effectively extending the length of the semi-circular tube 4. By adjusting the locking position of the locking block 1002, i.e., adjusting the length of the overlapping section between the extension tube 10 and the semi-circular tube 4, the extension distance of the extension tube 10 can be adjusted, making the device suitable for use with seedling trays of different widths, or simultaneously capable of fertilizing multiple rows of seedling trays, making it more convenient to use.
[0042] In some specific implementations, such as Figure 4 and Figure 5As shown, a pressure plate 11 is provided above the semicircular tube 4. Specifically, the hinge shaft of the semicircular tube 4 is made of screws. The screws pass through the pressure plate 11 and the semicircular tube 4 from top to bottom and are then threaded into the support frame 2. In this way, the end of the semicircular tube 4 near the application tank 1 can abut against the bottom surface of the pressure plate 11, effectively reducing the load on the hinge shaft of the semicircular tube 4. The hinge shaft of the semicircular tube 4 is not easily damaged, thereby improving the service life of the device.
