Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically to a water and fertilizer application device for winter wheat. Background Technology

[0002] Currently, winter wheat is mainly fertilized using the traditional "one-shot" fertilization method, with fertilizers being applied in large quantities as seed fertilizer. This results in high fertilizer concentration in the early stages, leading to uneven seedling growth and weak seedlings. As the winter wheat grows, the fertilizer in the soil is gradually lost, causing problems such as nutrient deficiency in the later stages, many shriveled grains, and low thousand-grain weight. These factors are all detrimental to increasing the yield of winter wheat.

[0003] Integrated water and fertilizer application technology is a new agricultural technology that combines irrigation and fertilization. It dissolves fertilizer in water through an irrigation system, and then delivers the mixed water and fertilizer to the crop according to its growth needs. It is suitable for fertilizing and irrigating winter wheat, and existing fertilization schemes have been developed that apply water and fertilizer application devices to the cultivation of winter wheat to increase its yield.

[0004] The spray angle of existing water and fertilizer application devices is difficult to adjust independently. In order to expand the fertilization range, the existing water and fertilizer application devices require manual operation of the fertilization device or hand-held spray pipe to keep turning during the fertilization process, which is difficult to operate and causes inconvenience to the fertilization of winter wheat.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0044] To address the technical problem that the spray angle of existing water and fertilizer application devices is difficult to adjust independently, causing inconvenience for winter wheat fertilization, this utility model provides a winter wheat water and fertilizer application device that enables range-based independent adjustment of the spray angle of water and fertilizer, thus providing convenience.

[0045] It should be noted that the winter wheat water and fertilizer application device described in this utility model is used for, but not limited to, the fertilization of winter wheat. For ease of explanation, this utility model only uses the application of the winter wheat water and fertilizer application device to the fertilization of winter wheat as an example. The principle of the winter wheat water and fertilizer application device applied to the fertilization of other crops is essentially the same as that applied to the fertilization of winter wheat, and will not be described in detail here.

[0046] Please see Figure 1 , Figure 1This invention relates to a winter wheat fertigation device, comprising a walking frame 10, a mixing tank 20, a water supply tank 30, a fertilizer tank 40, a discharge drive unit 50, a discharge pipe 60, and a swing drive unit 70. The mixing tank 20 is fixed to the walking frame 10 and has a mixing chamber 21. The water supply tank 30 is fixed to the walking frame 10 and communicates with the mixing chamber 21, for supplying water to the mixing chamber 21. The fertilizer tank 40 is fixed to the walking frame 10 and communicates with the mixing chamber 21, for supplying fertilizer to the mixing chamber 21. The discharge drive unit 50 is communicated with the mixing chamber 21 and drives the fertilizer to be discharged from the mixing chamber 21.

The outlets 41 of the water supply tank 30 and the fertilizer tank 40 are respectively connected to the water inlet 22 and the fertilizer outlet 23. Specifically, the water supply tank 30 has an outlet 31 on its lower side, and the fertilizer tank 40 has a discharge outlet 41 on its lower side. After the water and the prepared fertilizer are discharged from the outlet 31 and the discharge outlet 41, they enter the fertilizer outlet 23 of the funnel-shaped water inlet 22, and then enter the mixing tank 20 for mixing. After being mixed evenly in the mixing chamber 21, diluted fertilizer, i.e., liquid fertilizer, will be formed.

[0059] Preferably, please refer to Figure 1 The discharge drive unit 50 includes a drive pump 51 and a discharge pipe 52. The drive pump 51 is installed in the mixing tank 20 and connected to the mixing chamber 21. One end of the discharge pipe 52 is connected to the drive pump 51, and the other end of the discharge pipe 52 extends in the height direction of the walking frame 10. Specifically, the drive pump 51 can drive the high pressure of the mixed water and fertilizer to the discharge pipe 52, and then the discharge is completed by rising along the discharge pipe 52. The discharge pipe 52 extends in the height direction to facilitate the connection of the discharge pipe 60.

[0060] Preferably, please refer to Figure 1 The discharge pipe 60 includes a bend 61 and a spray pipe 62. One end of the bend 61 is rotatably connected to the end of the discharge pipe 52 away from the drive pump 51, and the other end of the bend 61 extends horizontally toward the traveling frame 10.

Specifically, the discharge pipe 60 can be rotatably connected to the discharge pipe 52 through the bend 61, and the extension state of the discharge pipe 52 is transformed into a horizontal state, so that the spray pipe 62 can extend, rotate, and spray in the horizontal direction.

[0061] In this embodiment, please refer to Figure 1 The end of the spray pipe 62 is equipped with a nozzle.

[0062] Preferably, please refer to Figure 1The oscillating drive unit 70 includes a drive shaft 71, a rotating shaft 72, a drive frame 73, and a rotating drive module 74. The drive shaft 71 is fixed to the discharge pipe 60 and has a straight groove 711. The rotating shaft 72 is rotatably connected to the traveling frame 10.

Since the drive frame 73 is slidably connected to the straight groove 711, the rotation of the drive frame 73 will drive the drive shaft 71 to oscillate continuously and slide along the side wall of the straight groove 711. Ultimately, the rotation of the drive frame 73 is converted into the oscillation of the drive shaft 71 within a certain range, which drives the discharge pipe 60 to oscillate back and forth, realizing the autonomous adjustment of the spraying angle of the discharge pipe 60, so that the discharge pipe 60 can automatically spray sand within the fan-shaped area.

The drive shaft 71 rotates on the support column 16, so that the drive shaft 71 will only swing around the support column 16 as the fulcrum, thereby improving the stability of the drive shaft 71 when swinging.

[0064] In this embodiment, the drive frame 73 is provided with a sliding protrusion (not shown in the figure). The sliding protrusion is slidably connected to the straight groove 711. During the rotation of the starter frame, the sliding protrusion slides back and forth along the straight groove 711 and drives the drive shaft 71 to swing back and forth.

Specifically, the rotating drive module 74 drives the second bevel gear 741 to rotate, thereby driving the first bevel gear 721 to rotate, ultimately achieving the driving of the rotating shaft 72.

[0067] Preferably, please refer to Figure 1The walking frame 10 is equipped with a support base 15. The rotary drive module 74 includes a motor 742, a belt 743, and a gear shaft 744. The gear shaft 744 is rotatably connected to the support base 15. The motor 742 is mounted on the mixing tank 20. The second bevel gear 741 is mounted on the gear shaft 744. The belt 743 is sleeved on the shaft of the gear shaft 744 and the motor 742. Specifically, when performing water-fertilizer sandblasting, when the motor 742 starts, it will drive the gear shaft 744 to rotate through the transmission of the belt 743. The rotation of the gear shaft 744 will drive the second bevel gear 741 to rotate, ultimately driving the rotary shaft 72 to realize the reciprocating oscillation of the discharge pipe 60.

[0068] Preferably, please refer to Figure 4 The water and fertilizer application device also includes a mixing frame 80, which is located in the mixing chamber 21 and connected to the shaft of the motor 742. Specifically, the mixing frame 80 is connected to the shaft of the motor 742, so that when the motor 742 drives the discharge pipe 60 to oscillate back and forth, it will synchronously drive the mixing frame 80 to rotate.
