Description

Technical Field

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

[0002] In the process of walnut cultivation, drip irrigation systems are usually used to irrigate walnuts. These systems mainly consist of five core parts: water source, head unit, main pipe, branch pipe, capillary pipe, and drippers. The head unit is responsible for the key functions of water filtration and water-fertilizer mixing. In this process, the fertilizer needs to be dissolved and stirred manually in advance before being added to the fertilizer tank. If the fertilizer and water are not fully dissolved, the undissolved solid particles will enter the main pipe along with the fertilizer and flow into the branch pipe and capillary pipe, eventually clogging the drippers and affecting the drip irrigation of walnut cultivation. Secondly, undissolved fertilizer particles that enter the main pipe directly are prone to remain in the pipe, resulting in fertilizer waste. Utility Model Content

[0003] To address the problems of fertilizer clogging the drippers due to insufficient dissolution of fertilizer and water, and fertilizer waste caused by fertilizer residue remaining in the pipes, the purpose of this utility model is to provide a drip irrigation device for walnut cultivation.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: A drip irrigation device for walnut planting, including a fertilizer tank, wherein the fertilizer tank includes a box body, a container body, a feeding pipe, and a water inlet pipe. The box body is fixedly connected to the container body, and the feeding pipe and water inlet pipe are fixedly connected to the container body. A slidable screen is provided inside the box body, and a reciprocating mechanism is provided at the top of the container body for shaking the slidable screen. The reciprocating mechanism includes a drive shaft, with rotating wheels fixedly installed at both ends of the drive shaft. A connecting rod is rotatably installed at the end of each rotating wheel away from the drive shaft. A support rod is rotatably installed at the bottom end of the connecting rod, and the support rod is fixedly connected to the slidable screen. A sleeve is slidably installed on the outside of the support rod through a locking block, and the sleeve is fixedly connected to the box body. The inside of the container body is provided with a slidable screen. The system includes a stirring mechanism for stirring undissolved fertilizer. The drive shaft is connected to the stirring shaft via a bevel gear. The stirring mechanism includes a worm gear with a worm wheel meshing on its outer side. A stirring shaft is fixedly mounted in the middle of the worm wheel and is rotatably connected to the tank. Two symmetrically distributed L-shaped support frames are fixedly mounted on the outside of the stirring shaft, and several evenly distributed stirring blades are fixedly mounted on the inner side of the support frames. A spiral conveying blade is fixedly mounted on the outer wall of the stirring shaft. Two symmetrically distributed stirring blades are fixedly mounted on the bottom end of the stirring shaft, with the length of the second stirring blade being longer than that of the first stirring blade. A scraper is fixedly mounted on the side of the support frame away from the first stirring blade, and the scraper is in contact with the inner wall of the tank.

[0005] Preferably, the bottom end of the screening screen is provided with an inclined guide plate, the guide plate is fixedly connected to the box body, a water outlet is provided through one side of the top of the guide plate, and a water outlet pipe is fixedly installed at the bottom end of the guide plate at the position of the water outlet, the water outlet pipe passes through the box body.

[0006] Preferably, a cover is fixedly installed at the top of the tank, one end of the worm gear rotates through the cover, and the drive shaft is rotatably connected to the cover.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application uses a screening screen to separate undissolved fertilizer particles from water, thus intercepting the particles and preventing them from flowing directly into the main pipe and clogging the drippers, which would affect the drip irrigation of walnuts. Furthermore, under the synergistic effect of the reciprocating mechanism and the screening screen, when the drive shaft rotates, the rotating wheel drives the connecting rod to move, and the connecting rod drives the support rod and the screening screen to vibrate up and down, effectively preventing undissolved fertilizer particles from clogging the screening screen. 2. This application sets up a stirring mechanism. The stirring shaft drives the support frame and stirring blades to rotate, thereby stirring the undissolved fertilizer particles and mixing them with water. In conjunction with the screening screen, the undissolved fertilizer will not enter the main pipe, effectively avoiding the retention of undissolved fertilizer particles in the main pipe and causing fertilizer waste. At the same time, it is not necessary to manually mix the fertilizer with water in advance, reducing labor input. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-6 As shown, this utility model provides a drip irrigation device for walnut planting, including a fertilizer tank 1. The fertilizer tank 1 includes a box body 11, a tank body 12, a feeding pipe 13, and a water inlet pipe 14. The box body 11 and the tank body 12 are fixedly connected. The feeding pipe 13 and the water inlet pipe 14 are fixedly connected to the tank body 12. A screening screen 2 is slidably provided inside the box body 11. A reciprocating mechanism 3 is provided at the top of the tank body 12. The reciprocating mechanism 3 is used to shake the screening screen 2. The reciprocating mechanism 3 includes a drive shaft 30, with a rotating wheel 31 fixedly installed at both ends of the drive shaft 30. A connecting rod 32 is rotatably installed at the end of each rotating wheel 31 away from the drive shaft 30. A support rod 33 is rotatably installed at the bottom end of the connecting rod 32. The support rod 33 is fixedly connected to the screening screen 2. A sleeve 34 is slidably installed on the outside of the support rod 33 through a locking block. The sleeve 34 is fixedly connected to the housing 11. The tank 12 is equipped with a stirring mechanism 4, which is used to stir undissolved fertilizer. By setting a sieve 2, the undissolved fertilizer particles and water are screened, so that the particles are intercepted and prevented from flowing directly into the main pipe, clogging the dripper and affecting the walnut drip irrigation. Under the synergistic action of the reciprocating mechanism 3 and the sieve 2, when the drive shaft 30 rotates, the rotating wheel 31 drives the connecting rod 32 to move. The connecting rod 32 drives the support rod 33 and the sieve 2 to shake up and down, effectively preventing undissolved fertilizer particles from clogging the sieve 2. The drive shaft 30 is supported by two symmetrically distributed supports, which are rotatably connected to the drive shaft 30 and fixedly connected to the tank 12. In actual use, a pipe cap or piston needs to be added to the feeding pipe 13.

[0018] The stirring mechanism 4 includes a worm gear 41, with a worm wheel 42 meshing with its outer side. A stirring shaft 43 is fixedly mounted in the middle of the worm wheel 42. The stirring shaft 43 is rotatably connected to the tank body 12. Two symmetrically distributed L-shaped support frames 44 are fixedly mounted on the outside of the stirring shaft 43, and several evenly distributed stirring blades 45 are fixedly mounted on the inner side of the support frames 44. By setting up the stirring mechanism 4, the stirring shaft 43 drives the support frames 44 and stirring blades 45 to rotate, thereby stirring the undissolved fertilizer granules. The mixing process mixes the fertilizer granules with water. In conjunction with the screening screen 2, it prevents undissolved fertilizer from entering the main pipe, effectively avoiding the waste of fertilizer caused by undissolved fertilizer granules remaining in the main pipe. At the same time, it eliminates the need for manual mixing of fertilizer and water in advance, reducing labor input. The worm gear 41 is driven by a motor, and the drive end of the motor can be connected to the worm gear 41 via a coupling. The worm gear 41 is supported by two symmetrically distributed supports 2, which are rotatably connected to the worm gear 41 and fixedly connected to the tank body 12.

[0019] A spiral conveyor blade 46 is fixedly installed on the outer wall of the stirring shaft 43; by setting the spiral conveyor blade 46, the mixed water can be conveyed upward while being stirred, effectively preventing undissolved fertilizer particles from settling.

[0020] Two symmetrically distributed stirring blades 47 are fixedly installed at the bottom of the stirring shaft 43. The length of stirring blade 47 is longer than that of stirring blade 45. By setting stirring blade 47, the mixed water in the tank 11 is stirred, and the stirring range is increased.

[0021] A scraper 48 is fixedly installed on the side of the support frame 44 away from the stirring blade 45. The scraper 48 is in contact with the inner wall of the tank 12. By setting the scraper 48, the inner wall of the tank 12 is cleaned, avoiding the adhesion of a small amount of undissolved fertilizer particles to the inner wall of the tank 12, which would cause fertilizer waste and improve the cleanliness of the inner wall of the tank 12.

[0022] The bottom end of the screening screen 2 is provided with an inclined guide plate 5, which is fixedly connected to the box body 11. A water outlet 51 is opened through one side of the top of the guide plate 5, and a water outlet pipe 52 is fixedly installed at the bottom end of the guide plate 5 at the position of the water outlet 51. The water outlet pipe 52 passes through the box body 11. By setting the guide plate 5, the screened water can be concentrated and discharged from the water outlet 51 and then discharged through the water outlet pipe 52, thus avoiding the waste of mixed water.

[0023] The drive shaft 30 and the stirring shaft 43 are connected by bevel gear meshing; so that when the stirring shaft 43 rotates, the drive shaft 30 will also rotate at the same time, driving the rotating wheel 31 to rotate.

[0024] A cover 6 is fixedly installed at the top of the tank body 12. One end of the worm gear 41 rotates through the cover 6, and the drive shaft 30 is rotatably connected to the cover 6. By setting the cover 6, the bevel gear, worm gear 41, and worm wheel 42 are protected to prevent external dust from adsorbing onto the bevel gear, worm gear 41, and worm wheel 42, which would affect the meshing between the bevel gears and the meshing between the worm gear 41 and the worm wheel 42.

[0025] Working principle: In actual use, the water pump outlet pipe is connected to the inlet pipe 14, and a control valve is installed between the outlet pipe 52 and the external main pipe. When drip irrigation is needed for walnuts, the water pump is started directly to draw water from the well / pond / reservoir. The water then passes through a filter device to filter out mud, sand and impurities. The filtered water enters the fertilizer tank 1, and then passes through the guide plate 5 and is discharged from the outlet 51. The water then flows through the outlet pipe 52 to the main pipe, branch pipe and capillary pipe, and flows out from the dripper to irrigate the walnuts. When it is necessary to fertilize the walnuts, firstly, the water pump is started to filter the water through the filter device and then enter the tank 12 and box 11. Then, the fertilizer is added to the fertilizer tank 1 through the feeding pipe 13. Before adding the fertilizer, the motor needs to be started. The motor drives the worm 41 to rotate. The meshing of the worm 41 and the worm wheel 42 drives the stirring shaft 43, support frame 44, stirring blade 1 45, spiral conveying blade 46, stirring blade 2 47, and scraper 48 to rotate, so as to mix the fertilizer and water. While the stirring shaft 43 rotates, the drive shaft 30 and the rotating wheel 31 are driven to rotate simultaneously through the meshing transmission of bevel gears. The rotation of the rotating wheel 31 causes the connecting rod 32 to move, pulling the support rod 33 to slide up and down inside the sleeve 34. The support rod 33 drives the screening screen 2 to shake back and forth inside the box 11. After mixing for a period of time, the control valve connected to the water outlet pipe 52 and the external main pipe is opened. The mixed water is discharged from the water outlet 51 through the guide plate 5, flows through the water outlet pipe 52 to the main pipe, branch pipe and capillary pipe, and flows out from the dripper to drip irrigate the walnuts. When the water is discharged, if there is still undissolved fertilizer, it will be screened by the screening screen 2, so that the fertilizer remains on the top of the tank 12 and the box 11, and the fertilizer and water are continuously mixed.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
