Description

Technical Field

[0001] The invention belongs to the technical field of planting and cultivation equipment, in particular to a seedling raising box for citrus planting. Background Art

[0002] The seedling box for citrus planting is a device specially used for cultivating citrus seedlings. It is usually composed of a cultivation box and a water tank. It adopts container seedling technology and uses nutrient soil or matrix to be loaded into the container to provide a suitable growth environment for the seedlings. At the same time, the management process can be simplified through an automated watering and fertilization system. However, the existing seedling boxes for citrus planting still have disadvantages in actual use: when replenishing water for citrus seedlings in the early stage, additional nutrients need to be added to improve the early growth environment of the seedlings, but the nutrients are prone to precipitation in the water pipe due to different solubility. The accumulation of a large amount of sediment will affect the normal spraying effect of the subsequent nozzles, thereby reducing the nutrient supplementation, so it needs to be improved. Summary of the invention

[0003] In order to solve the problem proposed in the above background technology that the nutrients used to improve the early growth environment of seedlings are prone to precipitation of a mixture of nutrients and water inside the water pipe due to different solubility, and the accumulation of a large amount of precipitation will affect the normal spraying effect of subsequent nozzles, thereby reducing nutrient supplementation, the present invention provides a seedling box for citrus planting.

[0004] To achieve the above object, the present invention provides the following technical solution: a citrus seedling raising box, comprising a seedling raising box, a connecting water pipe distributed at the top of the inner cavity of the seedling raising box, and an atomizing nozzle installed at the bottom of the connecting pipe and used for spraying the citrus seedlings, and also comprising:

[0005] A butt joint pipe, which is arranged below the connecting water pipe and communicates with the inner cavity of the connecting water pipe;

[0006] A scraper assembly installed inside the butt tube;

[0007] A power assembly, which is fixedly connected to both sides of the butt-joint pipe and is used to bend the lower end of the butt-joint pipe;

[0008] Wherein, the butt joint pipe comprises a pipe body, the pipe body is fixedly connected to the bottom of the connecting water pipe and communicated with the connecting water pipe, a stretch film is installed at the lower ends of both sides of the inner cavity of the pipe body, the bottom of the pipe body is communicated with the atomizing nozzle through a rubber connecting pipe, a baffle is installed inside the pipe body, and one side of the baffle abuts against a C-shaped abutment block connected to the pipe body through an elastic reset member;

[0009] The scraping assembly comprises a scraper engaged with the top of the baffle, and the scraper is fixedly connected to the stretch film through a drawstring;

[0010] The power assembly includes a baffle frame that bends the lower end of the rubber connecting tube and a servo motor. A second spur gear is fixedly connected to one end of the baffle frame away from the rubber connecting tube. One side of the second spur gear is fixedly connected to the output end of the servo motor. A crank connecting rod structure is meshed on the outer wall of the second spur gear.

[0011] Preferably, the baffle comprises two symmetrical groups of plate bodies which are respectively hinged to the inside of the tube body through a rotating shaft. Both ends of the rotating shaft are fixed with a first spur gear, and a bidirectional tooth plate is meshed and connected between the two first spur gears.

[0012] Preferably, transverse grooves are provided on both sides of the tube body for the scraper to slide, and the stretch film is installed in an "L" shape on both sides of the lower end of the inner cavity of the tube body;

[0013] The upper and lower ends of the stretch film are fixedly connected to the interior of the tube body, and the middle area of ​​the stretch film is movably fitted with the inner wall of the tube body. When the scraper drives the pull rope to gradually move in the inner cavity of the tube body toward the central area of ​​the tube body, the pull rope will pull the central area of ​​the stretch film outward. At this time, the seedling liquid located in the middle of the stretch film will move toward the middle area of ​​the tube body, thereby improving the mixing effect of the scraper and the seedling liquid.

[0014] Preferably, both ends of the C-shaped stop block are connected to the bottom end of the two-way tooth plate, and the contact end of the C-shaped stop block and the two-way tooth plate is provided with an oblique angle. The side of the C-shaped stop block away from the tube body is in contact with the atomizing nozzle. Due to the continuous flipping of the atomizing nozzle, when one end of the C-shaped stop block is pressed to gradually move toward one side of the rubber connecting tube, the oblique end of the C-shaped stop block will contact the two-way tooth plate, thereby causing the two-way tooth plate to move upward and causing the two-way tooth plate to drive the first spur gear meshing with it to move.

[0015] Preferably, the elastic reset members are provided in two groups, symmetrically mounted on both sides of the C-shaped stop block;

[0016] The elastic reset member is composed of a connecting rod fixed to the tube body and a spring for elastically connecting the connecting rod and the C-shaped stop block. One end of the connecting rod away from the tube body passes through the C-shaped stop block and is movably connected to the C-shaped stop block.

[0017] Preferably, the scrapers are provided in two groups and are staggeredly arranged in a grid-like manner in the inner cavity of the tube body. The connection ends of the scrapers and the crank-connecting rod structure are "L"-shaped and block the transverse grooves on the tube body. The scrapers are elastically connected to the tube body through a first spring.

[0018] Preferably, the servo motor is fixed on the positioning plate, the output end of the servo motor is fixed to the second spur gear, the outer wall of the second spur gear is meshed with the crank-connecting rod structure, and the top of the crank-connecting rod structure is fixed to the scraper.

[0019] Preferably, the second spur gear and the gear outer diameter of the crank-connecting rod structure directly meshing therewith are different, and the upper end area of ​​the crank-connecting rod structure is located in the middle area of ​​the bidirectional toothed plate and the tube body.

[0020] Preferably, the crank-connecting rod structure is composed of a first gear meshing with the second spur gear, a rotating meshing rod slidably connected to the outer wall of the gear, and a toothed plate meshing with the top of the rotating meshing rod;

[0021] The first gear is connected to the outer wall bearing of the tube body, the rotating engagement rod is rotatably connected to the tube body, and the tooth plate is fixedly connected to the scraper.

[0022] Preferably, the baffle is U-shaped, with both ends of the baffle fixedly connected to the second spur gear, the lower end of the baffle fits the outer wall of the lower end of the rubber connecting tube, and the side of the baffle close to the rubber connecting tube is fixedly connected to the lower end of the rubber connecting tube.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention cooperates with structures such as a tube body and a power component, and before using an atomizing nozzle to spray the citrus seedlings in a nursery box, the mixed liquid in the tube body is stirred, thereby avoiding large-area precipitation of the mixed liquid in the tube body. Through the cooperation of the crank-connecting rod structure and the scraper, the output end of the servo motor uses the crank-connecting rod structure to cause the scraper to perform mixing disturbance before the atomizing nozzle is about to spray, thereby performing a pretreatment in advance, improving the spraying effect, and avoiding the occurrence of sediment blocking the atomizing nozzle and affecting the spraying effect.

[0025] The present invention arranges a stretching film and a pull rope and other structures in coordination. When the scraper is driven by the crank-connecting rod structure to reciprocate inside the tube body, the stretching film is pulled by the pull rope, causing the stretching film to appear to be "shaking" at the side of the inner cavity of the tube body. In addition, the scraper is moved, so that the sediment in the lower end side area of ​​the inner cavity of the tube body is gathered to the center of the tube body, thereby improving the treatment effect of the mixed liquid sediment.

[0026] The present invention arranges the coordination of structures such as the atomizing nozzle and the power component. When the atomizing nozzle is not in use, the power component can be used to bend the rubber connecting tube and the atomizing nozzle to prevent leakage of the mixed liquid. At the same time, before the atomizing nozzle is operated, the scraping component is used to move the inside of the tube body, so there is no need to stop the device and spend a lot of time on processing, and it can be achieved during operation, thereby greatly improving the overall work efficiency.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, the present invention provides a citrus seedling box for planting, comprising a seedling box 1, a connecting water pipe 2 distributed at the top of the inner cavity of the seedling box 1, and an atomizing nozzle 4 installed at the bottom of a connecting pipe 3 and used for spraying citrus seedlings, and also comprising:

[0040] A butt joint pipe 3, which is arranged below the connecting water pipe 2 and communicates with the inner cavity of the connecting water pipe 2;

[0041] A scraping assembly 5, which is installed inside the butt-joint pipe 3;

[0042] A power assembly 6, which is fixedly connected to both sides of the butt-joint pipe 3 and is used to bend the lower end of the butt-joint pipe 3;

[0043] The butt joint pipe 3 includes a pipe body 31, which is fixedly connected to the bottom of the connecting water pipe 2 and communicated with the connecting water pipe 2. The lower ends of the inner cavity of the pipe body 31 are provided with stretching membranes 34. The bottom of the pipe body 31 is communicated with the atomizing nozzle 4 through a rubber connecting pipe 33. A baffle plate 32 is installed inside the pipe body 31. One side of the baffle plate 32 is abutted with a C-shaped abutment block 35 connected to the pipe body 31 through an elastic reset member 36.

[0044] The scraping assembly 5 includes a scraper 51 meshed with the top of the baffle 32, and the scraper 51 is fixedly connected to the stretch film 34 through a pull rope 52;

[0045] The power assembly 6 includes a baffle 64 that bends the lower end of the rubber connecting tube 33 and a servo motor 61. A second spur gear 62 is fixedly connected to one end of the baffle 64 away from the rubber connecting tube 33. One side of the second spur gear 62 is fixedly connected to the output end of the servo motor 61. A crank connecting rod structure 63 is meshed on the outer wall of the second spur gear 62.

[0046] like Figure 3 and Figure 7 As shown, the baffle 32 includes two symmetrical groups of plate bodies 321 which are hinged to the inside of the tube body 31 through a rotating shaft 322. Both ends of the rotating shaft 322 are fixedly connected with a first spur gear 324. A bidirectional tooth plate 325 is meshed and connected between the two first spur gears 324. The bidirectional tooth plate 325 is slidably connected to the tube body 31 through a positioning plate 37. A spring sheet 323 is installed on the rotating shaft 322 to reset the baffle 32.

[0047] With the above solution, when the bidirectional tooth plate 325 moves up and down, both sides of the bidirectional tooth plate 325 will simultaneously engage with the first spur gears 324 so that the two first spur gears 324 drive the spring plates 323 to rotate, thereby making the two plates 321 open or closed, and at the same time the spring plates 323 will reset the plates 321.

[0048] like Figure 3 and Fig.10 As shown, transverse grooves for the scraper 51 to slide are provided on both sides of the tube body 31, and the stretch film 34 is installed in an "L" shape on both sides of the lower end of the inner cavity of the tube body 31;

[0049] The upper and lower ends of the stretch film 34 are fixedly connected to the inside of the tube body 31 , and the middle area of ​​the stretch film 34 is movably fitted to the inner wall of the tube body 31 .

[0050] By adopting the above scheme: when the scraper 51 drives the pull rope 52 to gradually move in the inner cavity of the tube body 31 toward the central area of ​​the tube body 31, the pull rope 52 will pull the central area of ​​the stretch film 34 outward. At this time, the seedling liquid located in the middle of the stretch film 34 will move toward the middle area of ​​the tube body 31, thereby improving the mixing effect of the scraper 51 and the seedling liquid.

[0051] like Figure 7 and Fig.10 As shown, both ends of the C-shaped stopper 35 are in contact with the bottom end of the bidirectional tooth plate 325 , and the contact ends of the C-shaped stopper 35 and the bidirectional tooth plate 325 are provided with an oblique angle, and the side of the C-shaped stopper 35 away from the tube body 31 is in contact with the atomizing nozzle 4 .

[0052] By adopting the above scheme: one end of the C-shaped stopper 35 is pressed to gradually move toward one side of the rubber connecting tube 33 due to the continuous flipping of the atomizing nozzle 4, and the beveled end of the C-shaped stopper 35 will contact the bidirectional tooth plate 325, thereby causing the bidirectional tooth plate 325 to move upward and the bidirectional tooth plate 325 to drive the first spur gear 324 meshing with it to move.

[0053] like Figure 5 and Figure 8 As shown, two groups of elastic reset members 36 are provided, which are symmetrically installed on both sides of the C-shaped stop block 35;

[0054] The elastic reset member 36 is composed of a connecting rod fixed to the tube body 31 and a spring for elastically connecting the connecting rod and the C-shaped stop block 35 . One end of the connecting rod away from the tube body 31 passes through the C-shaped stop block 35 and is movably connected to the C-shaped stop block 35 .

[0055] Adopt the above scheme: through Figure 8 It can be seen that when the C-shaped stop block 35 is not in contact with the atomizing nozzle 4, the spring on the connecting rod of the elastic reset member 36 enables the C-shaped stop block 35 to achieve the reset purpose.

[0056] like Figure 3 and Figure 5 As shown, two groups of scrapers 51 are arranged in a grid-like manner and staggered in the inner cavity of the tube body 31. The connecting end of the scraper 51 and the crank connecting rod structure 63 is "L"-shaped and blocks the transverse groove on the tube body 31. The scraper 51 is elastically connected to the tube body 31 through a first spring 53.

[0057] like Figure 2 , Figure 4 and Fig.10 As shown, the servo motor 61 is fixed on the positioning plate 37 , the output end of the servo motor 61 is fixed to the second spur gear 62 , the outer wall of the second spur gear 62 is meshed with the crank connecting rod structure 63 , and the top of the crank connecting rod structure 63 is fixed to the scraper 51 .

[0058] like Fig.10 As shown, the gear outer diameter value of the second spur gear 62 and the crank connecting rod structure 63 directly meshing with it is different, and the upper end area of ​​the crank connecting rod structure 63 is located in the middle area of ​​the bidirectional toothed plate 325 and the tube body 31;

[0059] The crank connecting rod structure 63 is composed of a first gear meshing with the second spur gear 62, a rotating meshing rod slidably connected to the outer wall of the gear, and a toothed plate meshing with the top of the rotating meshing rod;

[0060] The first gear is connected to the outer wall bearing of the tube body 31 , the rotating engagement rod is rotatably connected to the tube body 31 , and the tooth plate is fixedly connected to the scraper plate 51 .

[0061] Adopt the above scheme: according to Fig.10 It can be concluded that when the output end of the servo motor 61 drives the second spur gear 62 to rotate, after the second spur gear 62 rotates one circle, the crank-connecting rod structure 63 gear directly meshed with the second spur gear 62 will rotate five to six circles, thereby allowing the scraper 51 meshed with the crank-connecting rod structure 63 to perform multiple reciprocating movements inside the tube body 31.

[0062] like Figure 5 and Fig. 9 As shown, the retaining frame 64 is U-shaped, with both ends of the retaining frame 64 fixedly connected to the second spur gear 62 , the lower end of the retaining frame 64 fits against the outer wall of the lower end of the rubber connecting tube 33 , and the side of the retaining frame 64 close to the rubber connecting tube 33 is fixedly connected to the lower end of the rubber connecting tube 33 .

[0063] The working principle and use process of the present invention:

[0064] First, when the atomizing nozzle 4 is not in use, the retaining frame 64 will resist the lower end of the rubber connecting tube 33, so that the lower end of the rubber connecting tube 33 is bent, and the distance between the atomizing nozzle 4 and the rubber connecting tube 33 will be larger than that of the atomizing nozzle 4. Figure 3 The interval value in is even smaller, and the inside of the rubber connecting tube 33 is blocked at this time;

[0065] Subsequently, when it is necessary to supplement nutrients for the citrus seedlings planted inside the nursery box 1, the servo motor 61 is operated so that its output end drives the baffle frame 64 to rotate, so that the bottom end of the baffle frame 64 gradually releases the interference effect on the lower end of the rubber connecting tube 33 and the atomizing nozzle 4. At the same time, as the output end of the servo motor 61 rotates, the second spur gear 62 drives the scraper 51 to move back and forth inside the tube body 31 through the crank connecting rod structure 63. While moving, the scraper 51 will pull the stretch film 34 in the inner cavity of the tube body 31 through the pull rope 52 to cause it to vibrate, so that the mixed liquid located on the side of the inner cavity of the tube body 31 will gather to the center of the inner cavity of the tube body 31, and through the swing of the two scrapers 51 in the inner cavity of the tube body 31, the precipitation of the mixed liquid is greatly avoided. The large-area accumulation phenomenon of the side of the tube body 31, thereby affecting the subsequent spraying effect of the atomizing nozzle 4.

[0066] Finally, when the retaining frame 64 gradually releases the contact with the bottom of the rubber connecting tube 33, so that the rubber connecting tube 33 gradually becomes vertical, the atomizing nozzle 4 will release the contact with the C-shaped block 35 after the servo motor 61 stops running, and the C-shaped block 35 will move to the side away from the tube body 31 through the elastic reset member 36. At the same time, the bottom end of the two-way tooth plate 325 moves downward after releasing the contact with the C-shaped block 35, so that the two plates 321 flip around the corresponding rotating shaft 322 as the axis, so that the mixed liquid in the inner cavity of the tube body 31 can enter the interior of the atomizing nozzle 4 through the rubber connecting tube 33 and be sprayed outward by the atomizing nozzle 4.
