Description

Technical Field

[0001] The invention belongs to the technical field of agricultural product cultivation, and in particular relates to a multifunctional water-fertilizer machine and a use method thereof. Background Art

[0002] In modern agricultural production, water-fertilizer integration technology has become an important means to improve crop yield and quality due to its advantages of efficient water-saving and precise fertilization. At present, farmland water-fertilizer operations are mainly divided into two key links: base fertilizer application and topdressing management. However, the equipment for these two operation scenarios in the existing technology has significant limitations.

[0003] During the application of basal fertilizer, the water fertilizer machine usually integrates a soil turning device and a spraying system as shown in CN211458015U. The soil is deeply turned over by turning over plows, rotary tillage blades and other components to destroy the soil compaction layer and loosen the soil. The basal fertilizer nozzle faces the ground and evenly mixes the fertilizer into the soil to meet the long-term demand for nutrients in the early growth of crops. Topdressing mostly occurs in the middle and late stages of crop growth. At this time, the root system of the plant has fully developed and the above-ground plants are dense. If a water fertilizer machine with a soil turning function is used, it will not only damage the crop root system and destroy the plant structure, but also may cause the fertilizer to fail to accurately reach the root of the crop due to soil turning, resulting in nutrient waste and environmental pollution.

[0004] Correspondingly, topdressing equipment is mostly single-function type, which sprays the stems and leaves of plants more widely through lateral spraying, but does not have the function of turning the soil. Either an additional soil-turning machine is required, or a water-fertilizer machine with soil-turning function is used.

[0005] Therefore, developing a multifunctional water-fertilizer machine that can take into account both base fertilizer turning over and fertilizing and topdressing lateral spraying, and matching it with corresponding usage methods, so as to achieve multiple uses of one machine, improve operating efficiency, and reduce production costs has become a technical problem that needs to be urgently solved in the current field of intelligent agricultural equipment.

Those skilled in the art can fully understand the present invention without the description of these details.

[0027] Please refer to Figures 1-6 , this embodiment provides a multifunctional water and fertilizer machine, which includes a water and fertilizer tank 91, and also includes a frame body 1, a baffle mechanism 2, a soil-turning mechanism 3, a driving mechanism 4, a feeding pump 5, a three-way valve 6, a base fertilizer nozzle 7 and a top dressing nozzle 8; The baffle mechanism 2 and the soil-turning mechanism 3 are respectively rotatably arranged on the frame body 1 and can respectively rotate towards the ground. There are two sets of baffle mechanisms 2 arranged oppositely. The soil-turning mechanism 3 is arranged between the two baffle mechanisms 2, and the baffle mechanism 2 and the soil-turning mechanism 3 can be self-locked; Specifically, the two baffle mechanisms 2 rotate towards or away from each other, and the rotation direction of the soil-turning mechanism 3 is perpendicular to the rotation axis of the baffle mechanism 2, that is, the baffle mechanism 2 rotates to the left and right sides, and the soil-turning mechanism 3 rotates forward and backward; when the soil-turning mechanism 3 rotates towards the ground, the two baffle mechanisms 2 rotate towards each other and towards the ground, and when the soil-turning mechanism 3 rotates away from the ground, the two baffle mechanisms 2 rotate away from each other and away from the ground; due to the self-locking characteristics of the baffle mechanism 2 and the soil-turning mechanism 3, they can be fixed in the rotated position. In the initial state, the baffle mechanism 2 and the soil-turning mechanism 3 are respectively located on the bottom surface of the bottom plate of the frame body 1 away from the ground.

[0028] The driving mechanism 4 is slidably arranged on the frame body 1 and can drive the soil-turning mechanism 3 and the baffle mechanism 2 to rotate; specifically, the driving mechanism 4 can drive the two baffle mechanisms 2 to rotate simultaneously, and the driving mechanism 4 makes a linear reciprocating motion.

[0029] The water and fertilizer tank 91, the feeding pump 5, the three-way valve 6, the base fertilizer nozzle 7 and the top dressing nozzle 8 are respectively arranged on the frame body 1.

When the driving mechanism 4 drives the soil-turning mechanism 3 to rotate towards the ground, it can be connected to the base fertilizer nozzle 7 through the three-way valve 6, and when the driving mechanism 4 drives the soil-turning mechanism 3 to rotate away from the ground, it can be connected to the top dressing nozzle 8 through the three-way valve 6.

[0030] Specifically, the three-way valve 6 is connected to the base fertilizer sprayer 7 and the topdressing sprayer 8 through pipelines. In the initial state, the driving mechanism 4 is located at the starting point of its stroke. The three-way valve 6 connects the topdressing sprayer 8 and the feeding pump 5. There are multiple topdressing sprayers 8, and their nozzles are respectively oriented towards the side and the ground, capable of spraying water and fertilizer at more angles. The soil-turning mechanism 3 and the baffle mechanism 2 are located at the highest point and close to the bottom surface of the frame 1. When the driving mechanism 4 slides towards the baffle mechanism 2, it drives the baffle mechanism 2 and the soil-turning mechanism 3 to rotate towards the ground. When it rotates to the lowest point, the driving mechanism 4 drives the three-way valve 6 to rotate to the state of connecting the base fertilizer sprayer 7. The base fertilizer sprayer 7 is arranged on the bottom surface of the frame 1 and oriented towards the ground, and is used for spraying the soil turned up by the soil-turning mechanism 3.

[0031] It should be understood that the water and fertilizer tank 91 has the same structure as the water and fertilizer tank 91 in the prior art, and can be a simple storage tank or a stirring tank capable of stirring, and is connected through the water tank 92, the fertilizer tank 93 and the corresponding conveying devices. Its specific structure is described in the prior art, and will not be elaborated herein in this application.

[0032] In this application, through the movement of the driving mechanism 4, while changing the angles of the baffle mechanism 2 and the soil-turning mechanism 3, the connection state between the base fertilizer sprayer 7 and the topdressing sprayer 8 is adjusted, so that when the soil-turning mechanism 3 and the baffle mechanism 2 turn towards the ground, the feeding pump 5 is connected to the base fertilizer sprayer 7, that is, it is converted into the state of spraying base fertilizer; when the base fertilizer spraying is completed or the base fertilizer spraying is no longer required, the driving mechanism 4 is returned to the initial state, driving the baffle mechanism 2 and the soil-turning mechanism 3 to approach the frame 1, and at the same time the three-way valve 6 is connected to the topdressing sprayer 8, realizing the topdressing spraying state. Thus, this application realizes the base fertilizer or topdressing spraying state by adjusting the state of the driving mechanism 4, without the need to additionally disassemble or replace other tools.
