Description

Technical Field

[0001] This utility model relates to the field of wheat planting technology, and in particular to a drip irrigation and fertilization device for wheat planting. Background Technology

[0002] Wheat is one of the world's most important food crops, and its cultivation requires careful consideration of various aspects, including variety selection, soil preparation, sowing management, water and fertilizer management, and pest and disease control. Its growth cycle is divided into seedling stage, tillering stage, jointing stage, heading stage, and grain-filling stage. The water and nutrient requirements vary significantly at each stage, and scientific management can significantly improve yield and quality. Drip irrigation fertilization (i.e., integrated water and fertilizer technology) combines irrigation and fertilization, precisely delivering water and nutrients to the vicinity of the wheat root system through drippers, offering numerous advantages over traditional irrigation fertilization methods (such as flood irrigation and broadcasting).

[0003] The integrated water and fertilizer system mainly consists of five systems. The water source and supply system provides clean water, including water source devices, pumps, and filters, ensuring stable water quality and quantity. The core of the fertilization system is the fertilizer applicator (such as a Venturi, differential pressure, or intelligent water and fertilizer machine), paired with a fertilizer tank and mixing device to achieve precise fertilizer injection. The pipeline system includes main and branch pipelines and drip and sprinkler irrigation terminals, responsible for transporting water and fertilizer. The control system achieves automated operation through controllers, sensors, and valves. There are also auxiliary components such as pressure gauges and check valves. All components work together to achieve precise water and fertilizer delivery, resulting in significant water and fertilizer savings and adaptability to different planting scenarios.

[0004] In existing technologies, for large farms, irrigation houses are usually built next to the wheat fields, and the integrated water and fertilizer equipment is installed inside the irrigation houses. However, for small farms or wheat fields that are scattered, the integrated water and fertilizer equipment needs to be disassembled and then transported by truck, which affects the efficiency of use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the operation of transferring drip irrigation and fertilization devices in wheat fields is cumbersome and troublesome, affecting the efficiency of use, and to propose a drip irrigation and fertilization device for wheat planting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drip irrigation and fertilization device for wheat cultivation includes a base on which a drip irrigation and fertilization section for drip irrigation is mounted; the drip irrigation and fertilization section is movably connected to a drip irrigation terminal to perform drip irrigation operations on wheat.

[0008] The drip irrigation fertilization unit includes a first water pump and a second water pump, a Venturi fertilizer applicator, a water and fertilizer tank, a filter section, and an irrigation pipe. One end of the first water pump is fixedly connected to the inlet pipe, and the other end is connected to one end of the filter section. One end of the second water pump is connected to the other end of the filter section through a fourth pipe, and the other end of the second water pump is fixedly connected to the irrigation pipe through the Venturi fertilizer applicator. The bottom of the water and fertilizer tank is fixedly connected to a sixth pipe, and the end of the sixth pipe away from the water and fertilizer tank is connected to the suction end of the Venturi fertilizer applicator.

[0009] In use, the water source is connected to the inlet pipe of the first water pump, and then the water flows through the filter section and enters the second water pump. When the second water pump supplies water to the irrigation pipe through the Venturi fertilizer applicator, the solution in the water-fertilizer tank is sucked away through the sixth pipe and enters the irrigation pipe together to realize drip irrigation fertilization.

[0010] The wheat drip irrigation and fertilization device also includes: two pairs of walking wheels, rotatably connected to the bottom of both ends of the base; and a traction frame, fixedly connected to the base. In use, the traction frame can be pulled by an agricultural vehicle, tractor, or tractor, thereby driving the walking wheels to rotate and realizing the movement of the drip irrigation and fertilization device.

[0011] Preferably, the traction frame includes symmetrically distributed first and second rods; the first and second rods are arranged in parallel, which reduces the lateral space occupied by the traction frame while ensuring its strength; or the extension lines of the first and second rods intersect, and the first and second rods are fixedly connected by a fixing cylinder, forming a triangular structure with the end face of the base, thereby improving the connection strength and ensuring the traction effect.

[0012] Preferably, the irrigation pipe and the drip irrigation terminal are connected in a detachable manner; the drip irrigation terminal includes a main pipe, branch pipes and drip irrigation tape, and the drip irrigation tape is laid in the wheat field.

[0013] Preferably, the base has a flat plate structure; the first and second water pumps, the filter section, and the water-fertilizer tank are all fixed on the base.

[0014] The water-fertilizer tank stores a mixture of liquid fertilizer or granular fertilizer and water. A feed pipe with a cap is fixedly connected to the top of the water-fertilizer tank for easy addition of fertilizer to improve the effect. The water-fertilizer tank is equipped with stirring blades, and the motor that drives the stirring blades is fixedly located on the top of the water-fertilizer tank.

[0015] The filter section is used to filter the irrigation water, reducing the occurrence of drip irrigation tape blockage.

[0016] Preferably, the filtration unit includes a centrifugal filter and a disc filter connected in series. The centrifugal filter first removes 70%-80% of large particles of silt, reducing the burden on the disc filter. The disc filter then intercepts the remaining fine impurities, achieving dual protection of "coarse filtration + fine filtration," significantly reducing the risk of clogging in pipelines and terminals (such as drip irrigation heads). Preferably, two sets of disc filters are used to improve filtration efficiency. The preferred model for the centrifugal filter is LS-SZLXGL, and the preferred model for the disc filter is QTDP-001.

[0017] The input and output ends of the centrifugal filter are fixedly connected to the first pipe and the second pipe, respectively. The first pipe is connected to the first water pump. The second pipe is fixedly connected to the input end of the disc filter. The output end of the disc filter is connected to the fourth pipe through the third pipe. A valve is fixedly connected to the third pipe.

[0018] In use, the water source is connected to the inlet pipe of the first water pump. The water flows through the first pipe into the centrifugal filter for filtration. After filtration, it then passes through the second pipe into the disc filter, and then through the third and fourth pipes into the second water pump. The second water pump supplies water to the irrigation pipe through the Venturi fertilizer applicator. The solution in the water-fertilizer tank is sucked away through the sixth pipe and enters the irrigation pipe together to realize drip irrigation fertilization.

[0019] Preferably, a control box is fixedly connected to the base. The control box contains circuitry for controlling the on / off state of the first water pump, the second water pump, and the motor, thereby improving the performance.

[0020] Preferably, a fifth pipe is fixedly connected to the top of the water-fertilizer tank, and the fifth pipe is connected to the fourth pipe. Valves are fixedly connected to both the fourth and fifth pipes. In use, water can be added to the water-fertilizer tank by closing the valve on the fourth pipe and opening the valve on the fifth pipe. After the water is added, the valve on the fourth pipe is opened and then the valve on the fifth pipe is closed. The second water pump can be started to pressurize and pump water for irrigation.

[0021] Preferably, the second water pump is fixedly connected to the seventh pipe, which is connected to the irrigation pipe, and a valve is fixedly connected to the seventh pipe; a valve is fixedly connected to the sixth pipe, and the extraction of solution in the water-fertilizer tank is controlled by closing or opening it.

[0022] Preferably, the inner diameter of the seventh pipe is larger than the inner diameter of the Venturi fertilizer applicator.

[0023] When in use, close the valve on the sixth pipe and open the valve on the seventh pipe. Since the inner diameter of the seventh pipe is larger than that of the Venturi fertilizer applicator, the second water pump can supply water directly to the irrigation pipe through the seventh pipe. Then, open the valve on the sixth pipe and slowly close the valve on the seventh pipe. This allows the solution in the water-fertilizer tank to be drawn from the Venturi fertilizer applicator and delivered to the irrigation pipe. The pressure of the water entering the Venturi fertilizer applicator can also be controlled through the valve on the seventh pipe, thus improving the effectiveness of the application.

[0024] A flange plate is fixedly connected to the end of the irrigation pipe away from the second water pump. A connecting pipe is fixedly connected to the flange plate. At least one groove, preferably three, is opened on the circumference of the connecting pipe, and the cross-section is arc-shaped.

[0025] When in use, if the main pipe is made of rigid material, a flange plate is installed on the main pipe to facilitate bolt connection with the flange plate on the irrigation pipe; if the main pipe is made of flexible material, it can be fitted onto the connecting pipe and then fixed to the connecting pipe with cable ties, straps, or clamps. The cable ties are located in the groove, which can reduce the possibility of slipping off the connecting pipe and improve the performance.

[0026] Compared with the prior art, this utility model provides a drip irrigation and fertilization device for wheat planting, which has the following beneficial effects:

[0027] 1. This wheat planting drip irrigation and fertilization device is designed by centrally installing the drip irrigation and fertilization unit on the base, and then installing the walking wheels at the bottom of the base. It can be moved by pushing the base. A traction frame is fixedly connected to one end of the base to facilitate towing by vehicle and improve the transfer efficiency.

[0028] 2. This drip irrigation and fertilization device for wheat planting allows for easy connection with the flange plate on the irrigation pipe by bolting when the main pipe is made of rigid material. When the main pipe is made of flexible material, it can be fitted onto the connecting pipe and then fixed to the connecting pipe with cable ties, straps, or clamps. The cable ties are located in the groove, which reduces the possibility of slipping off the connecting pipe and improves the usage effect. Attached Figure Description

When the second water pump 7 supplies water to the irrigation pipe 703 through the Venturi fertilizer applicator 702, the solution in the water-fertilizer tank 5 is sucked away through the sixth pipe 502 and enters the irrigation pipe 703 together to realize drip irrigation fertilization.

In use, the traction frame 101 can be towed by an agricultural vehicle, a tractor or a tractor, thereby driving the walking wheels 102 to rotate and realize the movement of the drip irrigation and fertilization device.

[0041] The traction frame 101 includes a first rod and a second rod that are symmetrically distributed.

The water-fertilizer tank 5 is equipped with stirring blades, and the motor that drives the stirring blades to rotate is fixedly installed on the top of the water-fertilizer tank 5.

[0045] The filter section is used to filter the irrigation water, reducing the occurrence of drip irrigation tape blockage.

[0046] The filtration section includes a centrifugal filter 3 and a disc filter 4, which are connected in series. The centrifugal filter 3 first removes 70%-80% of large particles of silt, reducing the burden on the disc filter 4. The disc filter 4 then intercepts the remaining fine impurities, achieving dual protection of "coarse filtration + fine filtration," significantly reducing the risk of clogging in pipelines and terminals (such as drip irrigation heads). Two sets of disc filters 4 are configured to improve filtration efficiency. The centrifugal filter 3 is model LS-SZLXGL, and the disc filter 4 is model QTDP-001.

[0048] In use, the water source is connected to the inlet pipe 201 of the first water pump 2. The water flows through the first pipe 301 into the centrifugal filter 3 for filtration. After filtration, it then passes through the second pipe 302 into the disc filter 4, and then through the third pipe 401 and the fourth pipe 402 into the second water pump 7. The second water pump 7 supplies water to the irrigation pipe 703 through the Venturi fertilizer applicator 702. The solution in the water-fertilizer tank 5 is sucked away through the sixth pipe 502 and enters the irrigation pipe 703 together to realize drip irrigation fertilization.

Valves are fixedly connected to both the fourth pipe 402 and the fifth pipe 501. In use, water can be added to the water-fertilizer tank 5 by closing the valve on the fourth pipe 402 and opening the valve on the fifth pipe 501. After the water is added, the valve on the fourth pipe 402 is opened and then the valve on the fifth pipe 501 is closed. The second water pump 7 can be started to pressurize and pump water for irrigation.

Then, open the valve on the sixth pipe 502 and slowly close the valve on the seventh pipe 701. This allows the solution in the water-fertilizer tank 5 to be extracted through the Venturi fertilizer applicator 702 and delivered to the irrigation pipe 703.
