Automatic water replenishment device for agricultural seedling trays

Abstract

This utility model discloses an automatic water replenishment device for agricultural seedling trays, including a sprinkler irrigation machine frame and an arm pipe. The arm pipe is clamped in the frame of the sprinkler irrigation machine and also includes a dual-position water replenishment mechanism. The dual-position water replenishment mechanism includes a U-shaped clamp, a concave wall pipe, a T-connector, a screw-on plug, a rubber disc pad, a bucket pipe, and a nozzle. By setting the dual-position water replenishment mechanism at the arm pipe of the sprinkler irrigation machine frame, the T-connector structure at the assembly point of the dual-position water replenishment mechanism at the arm pipe allows for quick switching of the sprinkler water supply path. Operators only need to screw on the screw-on plugs at both ends of the T-connector to quickly switch the sprinkler water path, allowing the water flow to be quickly switched at the two sets of bucket pipe inlet paths where nozzles are installed. If one set of sprinkler paths becomes blocked, it can quickly switch to the other set of sprinkler paths without requiring operators to go to the warehouse to retrieve and replace nozzles. This effectively ensures that the automatic water replenishment plan of the self-propelled sprinkler irrigation machine for the seedling trays proceeds according to the preset program.

Description

Technical Field

[0001] This utility model relates to the field of seedling tray water replenishment technology, and in particular to an automatic water replenishment device for agricultural seedling trays. Background Technology

[0002] Agricultural seedling trays, also known as seedling plug trays, are core equipment used in modern agriculture for large-scale seedling cultivation. Through standardized design, they provide seeds with independent growth space, significantly improving seedling efficiency and quality. When seedling trays are placed in greenhouses for seedling cultivation, parallel guide rails are usually laid along both sides of the seedling bed inside the greenhouse to install self-propelled sprinkler irrigation machines. The self-propelled sprinkler irrigation machines are connected to the water storage tank or municipal water supply inside the greenhouse. After passing through two stages of filtration, the water can automatically move after being programmed. Then, the long-arm pipes carry the nozzles to automatically replenish water to the seedling trays on the surface of the seedling bed.

[0003] In existing self-propelled sprinkler irrigation machines used for automatic watering of agricultural seedling trays, nozzles are installed at the pipes of the sprinkler irrigation machine to spray water downwards. When the nozzles become clogged, operators usually need to go to the warehouse to retrieve new nozzles for replacement. During the process of retrieving and replacing nozzles, the automatic watering plan of the agricultural seedling trays is affected, making it inconvenient for self-propelled sprinkler irrigation machines to be used for automatic watering of seedling trays. To address this, we propose an automatic watering device for agricultural seedling trays. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic water replenishment device for agricultural seedling trays. By setting a dual-position water replenishment mechanism at the arm pipe of the sprinkler irrigation machine, the dual-position water replenishment mechanism has a three-way pipe structure at the assembly point of the arm pipe that can quickly switch the sprinkler water supply path. The operator only needs to turn the screw plugs at both ends of the three-way pipe to quickly switch the sprinkler water outlet path, so that the water flow can be quickly switched at the water inlet path of the two sets of bucket pipes with sprinklers installed. If one set of sprinkler paths is blocked, it can quickly switch to the other set of sprinkler paths. There is no need for the operator to go to the warehouse to retrieve and replace the sprinklers. This effectively ensures that the automatic water replenishment plan of the self-propelled sprinkler irrigation machine for the seedling trays proceeds according to the preset program, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic water replenishment device for agricultural seedling trays includes a sprinkler frame and an arm pipe. The arm pipe is clamped to the frame of the sprinkler frame. The device also includes a dual-position water replenishment mechanism, which includes a U-shaped clamp, a concave-walled pipe, a tee pipe, a spin-pressing bolt, a rubber disc pad, a bucket pipe, and a nozzle. A concave-walled pipe is inserted into the lower nozzle of the arm pipe, and a U-shaped clamp is connected to the tee pipe. The seat of the U-shaped clamp is locked to the outside of the arm pipe by a spin-pressing bolt and a nut. A spin-pressing bolt is screwed onto both ends of the tee pipe, and a rubber disc pad is adhered to the head of the spin-pressing bolt when it is screwed into the tee pipe. A bucket pipe for drainage is symmetrically fixed to the tee pipe below the spin-pressing bolt, and a nozzle is screwed onto the bottom of the bucket pipe.

[0007] Furthermore, the outer wall of the concave-walled tube is provided with an annular concave surface, and a sealing ring is inserted into the annular concave surface of the concave-walled tube.

[0008] By adopting the above technical solution, the concave wall tube is firmly fitted with the sealing ring sleeve with the concave surface, and then the concave wall tube can be sealed and embedded at the lower nozzle of the arm tube with the sealing ring sleeve.

[0009] Furthermore, the U-shaped clamp has an arc-shaped groove recessed at the seat near the concave wall tube, and an arm tube is inserted into the arc-shaped groove of the U-shaped clamp.

[0010] By adopting the above technical solution, the U-shaped clamp can support the arm tube for clamping using the arc groove.

[0011] Furthermore, symmetrical holes for unscrewing the swivel bolt are provided at the U-shaped clamps on both sides of the arm tube, and nuts are screwed onto the bolt body where the swivel bolt is screwed out of the U-shaped clamp.

[0012] By adopting the above technical solution, after the U-shaped clamp is sleeved on the outside of the arm tube, the swivel bolt can be unscrewed out of the swivel hole of the U-shaped clamp and screwed into the nut, thereby locking the U-shaped clamp on the outside of the wall tube.

[0013] Furthermore, the two ends of the tee pipe are provided with threaded cavities for counterspinning, and a spin-forming plug is screwed into the counterspinning cavity;

[0014] By adopting the above technical solution, the spun bolt can be screwed into the opposite end of the tee pipe for installation.

[0015] Furthermore, the main body of the bucket pipe is integrally formed at the body of the tee pipe, and the water inlet of the bucket pipe is located at the tee pipe below the spinning bolt.

[0016] By adopting the above technical solution, the tee pipe can supply water to the large cavity of the bucket pipe. After the swivel bolt is screwed into the tee pipe, the rubber disc gasket, together with the swivel bolt, seals the inner pipe wall near the water inlet vertical pipe of the tee pipe, which can prevent water from entering the bucket pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model features a dual-position water replenishment mechanism installed at the arm pipe of the sprinkler irrigation machine. The dual-position water replenishment mechanism has a three-way pipe structure at the assembly point of the arm pipe that allows for quick and easy switching of the sprinkler water supply path. Operators only need to tighten the screws at both ends of the three-way pipe to quickly switch the sprinkler water outlet path, allowing the water flow to be quickly switched at the water inlet paths of the two sets of sprinkler heads. If one set of sprinkler paths becomes blocked, it can be quickly switched to the other set of sprinkler paths without requiring operators to go to the warehouse to retrieve and replace sprinkler heads. This effectively ensures that the automatic water replenishment plan of the self-propelled sprinkler irrigation machine for the seedling trays proceeds according to the preset program.

[0019] Furthermore, the U-shaped clamp above the three-way pipe of the dual-position water supply mechanism, with its own arc groove and the screw bolt and nut, can be firmly clamped to the outside of the arm pipe of the sprinkler, without the need for complex modifications to the original arm pipe. At the same time, the concave wall pipe of the U-shaped clamp can be tightly embedded in the lower nozzle of the arm pipe through the sealing ring sleeve clamped by the concave surface, effectively preventing water leakage from the connection and ensuring stable water supply pressure.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4As shown, the automatic water replenishment device for agricultural seedling trays includes a sprinkler pipe frame 1 and an arm pipe 2. The arm pipe 2 is clamped in the frame of the sprinkler pipe frame 1. It also includes a dual-position water replenishment mechanism 3. The dual-position water replenishment mechanism 3 includes a U-shaped clamp 4, a concave wall pipe 5, a three-way pipe 7, a spinneret 9, a rubber disc pad 10, a bucket pipe 11, and a nozzle 12. The concave wall pipe 5 is inserted into the lower nozzle of the arm pipe 2, and the concave wall pipe 5 and the three-way pipe 7 are interconnected by a U-shaped clamp 4. The seat of the U-shaped clamp 4 is locked and clamped to the outside of the arm pipe 2 by a spinneret 13 and a nut 14. The two ends of the three-way pipe 7 are screwed with spinnerets 9, and the head of the spinneret 9 is screwed into the head of the three-way pipe 7 and a rubber disc pad 10 is attached. The bucket pipe 11 for drainage is symmetrically fixed in the three-way pipe 7 below the spinneret 9, and the nozzle 12 is screwed into the bottom of the bucket pipe 11.

[0027] The concave wall tube 5 has an annular concave surface on its outer wall, and a sealing ring sleeve 6 is inserted into the annular concave surface of the concave wall tube 5.

[0028] By adopting the above technical solution, the concave wall tube 5 is firmly fitted with the sealing ring sleeve 6 with the concave surface, and then the concave wall tube 5 can be sealed and embedded at the lower nozzle of the arm tube 2 with the sealing ring sleeve 6.

[0029] The U-shaped clamp 4 is recessed at the seat of the concave wall tube 5 with an arc-shaped groove, and the arm tube 2 is inserted into the arc-shaped groove of the U-shaped clamp 4.

[0030] By adopting the above technical solution, the U-shaped clamp 4 can support the arm tube 2 for clamping using the arc groove.

[0031] Among them, the U-shaped clamps 4 on both sides of the arm tube 2 are symmetrically provided with screw holes for unscrewing the screw bolt 13, and the screw body of the screw bolt 13 is screwed with a nut 14 at the screw body where it is screwed out of the U-shaped clamp 4.

[0032] By adopting the above technical solution, after the U-shaped clamp 4 is fitted onto the outside of the arm tube 2, the screw bolt 13 can be screwed out of the screw hole of the U-shaped clamp 4 and screwed onto the nut 14, thereby locking the U-shaped clamp 4 onto the outside of the wall tube 2.

[0033] The three-way pipe 7 has threaded openings of counter-rotating ports 8 at both ends, and a spin-forming plug 9 is screwed into the counter-rotating ports 8.

[0034] By adopting the above technical solution, the spin-fitting bolt 9 can be screwed into the opposite spin port 8 of the tee pipe 7 for installation.

[0035] The main body of the bucket pipe 11 is integrally formed at the body of the three-way pipe 7, and the water inlet of the bucket pipe 11 is located at the three-way pipe 7 below the spinning bolt 9.

[0036] By adopting the above technical solution, the three-way pipe 7 can supply water to the large cavity of the bucket pipe 11. After the screw-in plug 9 is screwed into the three-way pipe 7, the rubber disc gasket 10, together with the screw-in plug 9, seals the inner pipe wall near the water inlet vertical pipe of the three-way pipe 7, which can prevent water from entering the bucket pipe 11.

[0037] It should be noted that this utility model is an automatic water replenishment device for agricultural seedling trays. By setting a double-position water replenishment mechanism 3 at the arm tube 2 of the sprinkler pipe frame 1, the U-shaped clamp 4 of the double-position water replenishment mechanism 3 can be clamped on the outside of the arm tube 2, so that the concave wall tube 5 inside the seat with the sealing ring sleeve 6 is embedded in the lower nozzle of the arm tube 2 for sealing and clamping. Then, the screw bolt 13 can be screwed out of the screw hole of the U-shaped clamp 4 and screwed with the nut 14, thereby locking the U-shaped clamp 4 on the outside of the wall tube 2. At this time, the screw bolt 9 of the rubber disc pad 10 can be screwed into the opposite screw at the opposite screw port 8 of the three-way pipe 7, so that the screw bolt 9 with the rubber disc pad 10 cuts off the water inlet of the bucket tube 11. Then the nozzle 12 can be screwed into the double tube body of the bucket tube 11 to complete the assembly of the double-position water replenishment mechanism 3.

[0038] When the inlet pipe of the arm pipe 2 is connected to an external pressurized water source, the screw 9 at one end of the three-way pipe 7 can be rotated outward a certain distance, so that the rubber disc pad 10 is blocked in the three-way pipe 7 between the bucket pipe 11 and the counter-rotating port 8. At this time, the water flow at the arm pipe 2 can flow into the bucket pipe 11 of the group through the concave wall pipe 5, the U-shaped clamp 4 and the cavity of the three-way pipe 7, and spray down along the nozzle 12 to spray and replenish the agricultural seedling tray. The sprinkler frame 1 can automatically move along with the self-propelled sprinkler according to the preset program to automatically replenish the agricultural seedling tray.

[0039] When blockage occurs at the set of bucket pipes 11 and nozzles 12, the screw-on plug 9 can be turned back to block the water inlet chamber of the bucket pipe 11 at that location. Then, the screw-on plug 9 at the other end of the tee pipe 7 can be turned off to expose the water inlet chamber of another set of bucket pipes 11, so that the spare bucket pipe 11 can be directly used with the nozzles 12 for water replenishment spraying.
