Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, specifically a drip irrigation maintenance system. Background Technology

[0002] Drip irrigation is a fertilization method that uses equipment such as drippers, drip tapes, and fertilizer tanks to deliver pressurized water through pipes to the roots of plants, and then slowly drips it into the soil near the crop roots, drop by drop.

[0003] This drip irrigation method enables water to be precisely delivered to the roots of crops, avoiding excessive water waste and creating a good soil moisture environment for the crop roots. This drip irrigation system, which consists of drippers, drip tape, and fertilizer tanks, can be called a drip irrigation maintenance system.

[0004] However, in existing drip irrigation maintenance systems, fertilizer may adhere to the inner wall of the fertilizer tank during long-term use. This fertilizer may breed bacteria, algae, and other microorganisms, which could contaminate the water quality of the entire drip irrigation system. To prevent this, some existing fertilizer tanks have scrapers added to the stirring rod inside. These scrapers scrape the inner wall of the fertilizer tank while stirring it, preventing fertilizer from adhering to the inner wall. However, with increased use, the scrapers will gradually wear down. When the scrapers are worn too much and no longer contact the inner wall of the fertilizer tank, they can no longer scrape the fertilizer. Therefore, this system does not meet the current requirements. To address this, we propose a new drip irrigation maintenance system. Utility Model Content

[0005] The purpose of this invention is to provide a drip irrigation maintenance system to solve the problems mentioned in the background art, such as fertilizer sticking to the inner wall of the fertilizer tank in existing drip irrigation maintenance systems during long-term use. This fertilizer may breed bacteria, algae, and other microorganisms, which could contaminate the water quality of the entire drip irrigation system. To prevent this, some existing fertilizer tanks have scrapers added to the stirring rod inside, which simultaneously scrape the inner wall of the fertilizer tank during the stirring process, thus preventing fertilizer from adhering to the inner wall. However, with increased use, the scrapers gradually wear down. When the scrapers are worn too severely and no longer contact the inner wall of the fertilizer tank, it becomes impossible to continue scraping the fertilizer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drip irrigation maintenance system, including a drip irrigation fertilizer tank, the drip irrigation fertilizer tank containing a stirring shaft, a single-cylinder fixedly installed inside the outer shell of the drip irrigation fertilizer tank at the rear of the stirring shaft, a pusher head connected to the piston rod of the single-cylinder cylinder, a roller bearing rod connected to the front end face of the pusher head via a roller bearing, a pusher rod located inside the stirring shaft in front of the roller bearing rod, a pusher plate fixed on both sides of the upper and lower end faces of the pusher rod, one side of the front end face of the pusher plate being an inclined surface, a suitable connecting rod in front of the inclined surface, a scraper fixed on the upper end face of the two suitable connecting rods above the pusher rod, and a scraper fixed on the lower end face of the two suitable connecting rods below the pusher rod.

[0007] Preferably, a metal ring is fixedly sleeved on the outer surface of the suitable connecting rod, and a spring is connected to the upper end face of the metal ring located above the push rod and the lower end face of the metal ring located below the push rod.

[0008] Preferably, a stirring motor is fixedly installed inside the outer shell of the drip irrigation fertilizer tank in front of the stirring shaft, and the output shaft of the stirring motor is connected to the front end face of the stirring shaft through a coupling.

[0009] Preferably, the scraper includes a base plate and a scraping head, the scraping head is fixed to the outer surface of the base plate, and the shape of the scraping head corresponds to the shape of the inner wall of the drip irrigation fertilizer tank.

[0010] Preferably, an extraction pipe is installed on one side of the lower end face of the drip irrigation fertilizer tank, and a diversion pipe is connected to the rear end face of the extraction pipe.

[0011] Preferably, the fertilizer tank for drip irrigation has a filling port at the middle position of the upper end face, and the filling port contains a sealing head inside.

[0012] Preferably, a protective cover is provided above both the stirring motor and the single-cylinder on the outer surface of the drip irrigation fertilizer tank, and the protective cover is fixed to the drip irrigation fertilizer tank by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a single-cylinder installed inside the outer shell of a drip irrigation fertilizer tank to simultaneously push two scrapers located above and below the stirring shaft. Through this technical solution, operators can dynamically adjust the distance and contact force between the scrapers and the inner wall of the drip irrigation fertilizer tank based on the wear condition of the scrapers. This ensures that even scrapers that have worn down significantly due to prolonged use remain in contact with the inner wall of the drip irrigation fertilizer tank for fertilizer removal.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The drip irrigation fertilizer tank 1 (model 25L), stirring motor 4 (model DM542) and single-cylinder cylinder 5 (model SC-32) mentioned in this utility model can be obtained from the market or through private customization.

[0022] Please see Figures 1 to 4 This utility model provides an embodiment of a drip irrigation maintenance system, including a drip irrigation fertilizer tank 1. The drip irrigation fertilizer tank 1 contains a stirring shaft 6. A single-cylinder cylinder 5 is fixedly installed inside the outer shell of the drip irrigation fertilizer tank 1 behind the stirring shaft 6. The piston rod of the single-cylinder cylinder 5 is connected to a pusher head 7. The front end face of the pusher head 7 is connected to a roller bearing rod 8 through a roller bearing. A pusher rod 9 located inside the stirring shaft 6 is located in front of the roller bearing rod 8. A pusher plate 10 is fixed on both sides of the upper and lower end faces of the pusher rod 9. One side of the front end face of the pusher plate 10 is an inclined surface 11. A suitable connecting rod 12 is located in front of the inclined surface 11. A scraper 15 is fixed on the upper end face of the two suitable connecting rods 12 located above the pusher rod 9. A scraper 15 is fixed on the lower end face of the two suitable connecting rods 12 located below the pusher rod 9.

[0023] The drip irrigation fertilizer tank 1 has a filling port in the middle of the upper end face, and the filling port contains a sealing head; when the equipment needs to be used, waste material is added into the drip irrigation fertilizer tank 1 through the filling port.

[0024] A stirring motor 4 is fixedly installed inside the outer shell of the drip irrigation fertilizer tank 1 in front of the stirring shaft 6. The output shaft of the stirring motor 4 is connected to the front end face of the stirring shaft 6 through a coupling. The scraper 15 includes a base plate and a scraping head. The scraping head is fixed to the outer surface of the base plate, and the shape of the scraping head corresponds to the shape of the inner wall of the drip irrigation fertilizer tank 1. An extraction pipe 2 is installed on one side of the lower end face of the drip irrigation fertilizer tank 1, and a diversion pipe 3 is connected to the rear end face of the extraction pipe 2. After the fertilizer is added, water is added into the drip irrigation fertilizer tank 1, and then the stirring motor 4 is started. The stirring motor 4 can drive the stirring shaft 6 connected to it to rotate. The rotating stirring shaft 6 can mix the water and fertilizer added into the drip irrigation fertilizer tank 1. After the mixing is completed, the water mixed with fertilizer is extracted through the extraction pipe 2 and input into the diversion pipe 3 for drip irrigation.

[0025] Before starting the mixing shaft 6 for mixing, the single-cylinder cylinder 5 is activated to push the roller bearing rod 8 connected to it via the pusher head 7 forward. As the roller bearing rod 8 moves forward, it will contact the pusher rod 9 and push the pusher rod 9 forward. As the pusher rod 9 moves forward, the four pusher plates 10 fixed to the outer surface of the pusher rod 9 will move forward together. As the pusher plate 10 moves forward, the inclined surface 11 on the outer surface of the pusher plate 10 will contact the suitable connecting rod 12. Under the action of the inclined surface 11, the suitable connecting rod 12 will be pushed outward as the pusher plate 10 moves forward. As the suitable connecting rod 12 moves, the scraper 15 fixed to it will move outward together. Through the above technical solution, the operator can dynamically adjust the distance and contact force between the scraper 15 and the inner wall of the drip irrigation fertilizer tank 1 according to the wear condition of the scraper 15. This ensures that the scraper 15, which is more severely worn due to long-term use, can always be in contact with the inner wall of the drip irrigation fertilizer tank 1 for fertilizer scraping.

[0026] When the roller bearing rod 8 located inside the stirring shaft 6 is driven to rotate along with the rotating stirring shaft 6, the push head 7 will not rotate along with it due to the roller bearing structure between the push head 7 and the roller bearing rod 8. The above technical solution can prevent the rotational force of the stirring shaft 6 from being transmitted to the piston rod of the single-cylinder 5 through the roller bearing rod 8 and the push head 7, thereby preventing damage to it.

[0027] A metal ring 13 is fixedly sleeved on the outer surface of the suitable connecting rod 12. A spring 14 is connected to the upper end face of the metal ring 13 above the push rod 9 and the lower end face of the metal ring 13 below the push rod 9. When the suitable connecting rod 12 is pushed outward, the metal ring 13 fixed to it will move outward together and compress the spring 14.

[0028] When liquid fertilizer needs to be mixed with water, the single-cylinder cylinder 5 pulls the roller bearing rod 8 back to its original position. As the roller bearing rod 8 moves back to its original position, the reaction force of the compressed spring 14 pushes the scraper 15 back to its original position, thereby relieving the contact between the scraper 15 and the inner wall of the drip irrigation fertilizer tank 1. By relieving the contact between the two, the scraper 15 can be prevented from undergoing meaningless wear.

[0029] A protective cover is provided above the mixing motor 4 and the single-cylinder cylinder 5 on the outer surface of the drip irrigation fertilizer tank 1, and the protective cover is fixed to the drip irrigation fertilizer tank 1 by screws; the protective cover can seal and protect the mixing motor 4 and the single-cylinder cylinder 5.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
