Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage intercropping vertical rotation layered fertilization device. Background Art

[0002] Stratified fertilization, which applies fertilizer to different soil layers based on crop root growth and fertilizer requirements, ensures sufficient nutrients for crops at each growth stage, thereby increasing yields. This approach is a key agricultural research topic in my country. With population growth and increasing demand for agricultural products, there is a need to increase crop yields. However, traditional fertilization methods often result in low fertilizer utilization rates, making it difficult to meet the nutrient needs of crops at different growth stages.

[0003] Currently, most existing fertilizer spreaders that simultaneously open trenches and layer the soil use plowshares for furrowing. These are typically used after land preparation, as the soil is loose and requires less force to open the trenches. Using plowshares before land preparation requires significant traction, which is energy-consuming and time-consuming. Consequently, research on furrowing before land preparation is relatively limited, resulting in a lack of effective methods for furrowing different soil layers before land preparation. Fertilization can only be performed after land preparation, resulting in a waste of manpower and material resources.

[0004] Therefore, at this stage, there is a need for a fertilizer spreader that can fertilize in deep and shallow layers before land preparation. Summary of the Invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems and provide a no-till intercropping vertical rotary layered fertilization device, in which a deep fertilization device and a shallow fertilization device are successively arranged along the traveling direction. The deep and shallow soils are first loosened by the drill bit, spiral cutter shaft and spiral blades of the deep fertilization device, and fertilizer is transported to the deep soil through the central control channel on the spiral cutter shaft. After the shallow soil is loosened, the traction force required for the plow of the shallow fertilization device to open furrows can be reduced, making it easier for the plow to open furrows in the shallow soil.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments analyzed and obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] The purpose of the present invention is to provide a no-till intercropping vertical rotary layered fertilization device to solve the problems existing in the prior art: the deep and shallow soils are first loosened by the drill bit, spiral cutter shaft and spiral blades of the deep fertilization device, and the hollow channel of the spiral cutter shaft of the deep fertilization device can be used to apply fertilizer during the process of the spiral blades loosening the deep soil. The loosened shallow soil can reduce the traction force required for the plow of the shallow fertilization device to open furrows, making it easier for the plow to open furrows in the shallow soil. The fertilizer pipe of the shallow fertilization device can fertilize the shallow land during the plow opening furrows. The no-till intercropping vertical rotary layered fertilization device realizes fertilization of soils of different depths before land preparation, thereby meeting the fertilizer needs of crop roots at different stages.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 8 As shown, this embodiment provides a no-till intercropping vertical rotary layered fertilization device, which includes a frame 1. The frame 1 is made of metal material or other high-hardness material. A fertilizer box 2, a deep fertilization device and a shallow fertilization device are provided on the frame 1. The fertilizer box 2 is fixed to the frame 1 by a fixed connection method such as welding or bolts.

[0035] The connecting end on the frame 1 is connected to a traveling device (such as a tractor, etc.), and a lifting mechanism is provided on the traveling device. The lifting mechanism on the traveling device is used to control the lifting of the frame 1, and the traveling device is used to drive the frame 1 to move.

[0036] The deep fertilization device includes a spiral cutter shaft 3, a spiral blade 4, and a drill bit 27. The spiral cutter shaft 3, spiral blade 4, and drill bit 27 are all made of metal and are fixedly connected by welding or bolts. The spiral cutter shaft 3 is arranged vertically to ensure that the spiral cutter shaft 3 can be vertically screwed into the soil during the tillage process. A hollow channel is provided in the spiral cutter shaft 3. The hollow channel is connected to the fertilizer box 2, allowing the fertilizer in the fertilizer box 2 to enter the hollow channel of the spiral cutter shaft 3. A fertilizer outlet 31 is provided on the side wall at the bottom of the spiral cutter shaft 3. The drill bit 27 is installed at the bottom of the spiral cutter shaft 3 and is used to drill down and break the soil. After the fertilizer in the fertilizer box 2 enters the hollow channel, it can be thrown out through the fertilizer outlet 31 to achieve fertilization. Specifically, the top of the hollow channel is connected to the bottom of the fertilizer box 2, and the fertilizer in the fertilizer box 2 enters the spiral cutter shaft 3 through the hollow pipe. After the deep fertilization device finishes tilling, the spiral cutter shaft 3 and the spiral blade 4 change the direction of loosening the soil, so that the rotation direction is from bottom to top, thereby realizing the soil covering function.

[0037] The shallow fertilization device includes a coulter and a fertilizer pipe 7. The fertilizer pipe 7 is connected to the fertilizer tank 2 to ensure that the shallow fertilization device can apply fertilizer. With the direction of the layered fertilization device as the front, the shallow fertilization device is located in the front, and the shallow fertilization device is located in the rear. In the shallow fertilization device, the coulter can be a furrowing curved coulter. The fertilizer pipe 7 is installed behind the coulter. Preferably, the fertilizer pipe 7 includes a round tube and a hose, and the round tube is welded to the rear of the coulter. After the coulter plows the land, the fertilizer pipe 7 can then apply fertilizer, which both facilitates fertilization and protects the fertilizer pipe 7. The lowest point of the coulter in the vertical direction is higher than the lowest point of the spiral cutter shaft 3. The deep fertilization device with the spiral cutter shaft 3 is responsible for plowing the unplowed land in the front and applying fertilizer to the deep soil, while the coulter is responsible for separating the plowed land and applying fertilizer to the shallow soil, so that plowing, deep fertilization, and shallow fertilization can be carried out simultaneously.

[0038] Working Principle: After connecting the frame 1 to the lifting mechanism of a traveling device (such as a tractor), the spiral cutter shaft 3 of the deep fertilization device rotates. The lifting mechanism on the traveling device controls the descent of the frame 1. As the deep fertilization device rotates, the drill bit 27 first breaks up the soil. Then, the spiral cutter shaft 3 and spiral blades 4 rotate and plow into the soil. After the spiral blades rotate to a certain depth (e.g., 20 cm), the traveling device drives the frame 1 forward. As the frame 1 advances, the spiral cutter shaft 3 and spiral blades 4 loosen both the deep and shallow layers of soil. The fertilizer box 2 supplies fertilizer to the spiral cutter shaft 3 through a hollow channel. The fertilizer is then dispensed into the deep soil through the fertilizer outlet 31, achieving deep soil fertilization. As the coulter behind the spiral cutter shaft 3 advances, it plows the loosened shallow soil and applies fertilizer to the shallow soil through the fertilizer pipe 7.

[0039] In one embodiment, the drill bit 27 includes a mounting disc 28, a spreading plate 29, and a conical head 30. The top surface of the mounting disc 28 is coaxially fixedly connected to the bottom of the spiral cutter shaft 3 (welding or bolting installation can be adopted). Three fertilizer outlets 31 are circumferentially arranged on the spiral cutter shaft. There are three spreading plates 29, which are eccentrically arranged on the mounting disc 28 (welding or bolting installation can be adopted), and the three spreading plates 29 extend out of three fertilizer outlets 31 respectively. During the rotation process, the three spreading plates 29 can cause the fertilizer falling in the hollow pipe of the spiral cutter shaft 3 to be spread outward. The conical head 30 is coaxially fixed on the bottom surface of the mounting disc 28 (welding or bolting installation can be adopted), and the tip of the conical head 30 is downward for trenching and loosening the soil.

[0040] In one embodiment, one end of each of the three spreading plates 29 extends beyond the fertilizer outlet 31, while the other end is close to but not in contact with the other two spreading plates 29. This creates a gap between the adjacent ends of the three spreading plates 29, allowing fertilizer to pass through the gap to a position away from the center of the circle and then be dispersed along any spreading plate 2 through its corresponding fertilizer outlet 31, thus avoiding residue. Preferably, the three spreading plates 29 are eccentrically disposed relative to the center of the mounting disc 28, and the central axes of the three spreading plates 29 form a cotangent circle.

[0041] In one embodiment, the spiral cutter shaft 3 can also be tilted to improve the efficiency of spiral tillage.

[0042] In one embodiment, the fertilizer box 2 includes a front fertilizer box 19 and a rear fertilizer box 20. The front fertilizer box 19 is used to hold fertilizer, while the rear fertilizer box 20 is used to hold fertilizer. The front fertilizer box 19 is used to apply fertilizer to the deep soil layer, while the rear fertilizer box 20 is used to apply fertilizer to the shallow soil layer. After the seeds germinate, their roots grow downward and absorb the fertilizer from the deep soil layer. In addition, the rear fertilizer box 20 can also hold seeds as needed.

[0043] A first fertilizer discharger 17 is installed at the discharge port of the front fertilizer box 19.

A second fertilizer discharger 18 is installed at the discharge port of the rear fertilizer box 20. The second fertilizer discharger 18 is also a spiral shaft fertilizer discharger. The second fertilizer discharger 18 can discharge the fertilizer or seed content in the rear fertilizer box 20 into the fertilizer pipe 7, and the amount of fertilizer applied is controlled by the second fertilizer discharger 18.

The other end of the second fertilizer discharger transmission rod 26 is used to pass through the axis of the second fertilizer discharger 18 and be fixedly connected to the axis of the second fertilizer discharger 18, so that the axis of the second fertilizer discharger 18 can rotate with the rotation of the second fertilizer discharger transmission rod 26, thereby driving the second fertilizer discharger 18 to rotate through the second fertilizer discharger transmission rod 26.

[0045] With the forward direction of the entire device as the front, the first motor 23 is arranged outside the fertilizer box side plate 22 located on the right, and the second motor 24 is arranged outside the fertilizer box side plate 22 located on the left.
