Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology, and in particular to a tobacco stratified fertilization trencher. Background Technology

[0002] Tobacco is the main raw material for the cigarette industry, and it is divided into flue-cured, sun-cured, and air-cured tobacco. Among them, flue-cured tobacco has the largest cultivation area globally and is used to make cigarettes. In the process of tobacco cultivation, scientific fertilization methods are crucial to the growth, development, yield, and quality of tobacco. The nutrient requirements of tobacco vary at different growth stages, and different types of fertilizers (such as base fertilizer and top dressing) have different suitable burial depths in the soil. Generally, base fertilizer needs to be applied to a deeper soil layer to meet the long-term absorption needs of tobacco roots, while top dressing is applied to a shallower soil layer for rapid nutrient supply.

[0003] Existing stratified fertilizer applicators fix the upper and lower fertilizer application components to the same vertical rod, with no gap between them in the horizontal space. This results in the upper and lower fertilizer application openings being too close together. After trenching and fertilization, the upper fertilizer layer is easily carried into the deeper layers when the soil flows back. This not only makes the fertilizer layering in the soil unclear, but also makes the ratio of the upper and lower fertilizer layers too random, seriously affecting the fertilization quality. To address these issues, we propose a tobacco stratified fertilizer trenching device. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco stratified fertilization trencher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tobacco stratified fertilization trencher includes a crossbeam. A mounting groove is formed on the left side of the crossbeam, and a trenching component is installed inside the mounting groove. A deep fertilization pipe is fixedly connected inside the crossbeam. A movable beam is slidably connected to the outer surface of the crossbeam. Several first adjustment holes are formed on the upper surface of the crossbeam. A first positioning hole is formed on the upper surface of the movable beam. A positioning bolt is threadedly connected to the interior of one of the first adjustment holes and the interior of the first positioning hole. A sliding groove is formed on the right side of the crossbeam, and a sliding seat is slidably connected inside the sliding groove. A shallow fertilization pipe is fixedly connected inside the sliding seat. Symmetrical second positioning holes are formed on the outer surface of the movable beam. Several second adjustment holes are formed inside the sliding seat. A first bolt is threadedly connected to the interior of two of the second positioning holes and the interior of one of the second adjustment holes. One end of the first bolt is threadedly connected to a first nut. A diversion component is fixedly connected to the bottom ends of both the deep and shallow fertilization pipes.

[0007] In a further embodiment, both of the diversion components include a housing, the upper surfaces of the two housings are respectively connected to the bottom end of the deep fertilization pipe and the bottom end of the shallow fertilization pipe, and a diversion block is fixedly connected inside the two housings, and a flow hole is opened inside the two diversion blocks.

[0008] In a further embodiment, the trenching assembly includes a vertical beam, the outer surface of which is slidably connected to the inner wall of the mounting groove, and a trenching cutter is fixedly connected to the left side of the vertical beam.

[0009] In a further embodiment, mounting holes are provided on the outer surface of the crossbeam and inside the vertical beam, and a second bolt is provided inside each set of mounting holes, with a second nut threaded to one end of the second bolt.

[0010] In a further embodiment, a reinforcing block is fixedly connected to the right side of the vertical beam, and the upper surface of the reinforcing block is in close contact with the bottom surface of the horizontal beam.

[0011] In a further embodiment, the top end of the deep fertilization pipe is fixedly connected to a first flexible hose, and the top end of the shallow fertilization pipe is fixedly connected to a second flexible hose.

[0012] In a further embodiment, a first valve is fixedly installed on the outer surface of the first hose, and a second valve is fixedly installed on the outer surface of the second hose.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This device can flexibly adjust the horizontal distance between the deep fertilizer pipe and the shallow fertilizer pipe through the sliding adjustment structure of the crossbeam and the movable beam. When the equipment is fertilizing in trenches, the deep fertilizer and the shallow fertilizer form a clear spatial separation in the soil, which avoids the upper fertilizer from being mixed into the deep layer with the soil backflow. This solves the problem of unclear fertilizer stratification in the soil, which seriously affects the quality of fertilization.

[0015] 2. This device connects the bottom ends of both the deep and shallow fertilization pipes to a diversion component. This component, through the diversion block and flow holes inside the outer shell, disperses the delivered fertilizer into multiple streams that fall evenly. This effectively avoids the problem of excessive local nutrients caused by the single-point concentrated fertilization of traditional fertilization pipes, thereby reducing the risk of tobacco root burn, while improving fertilizer utilization and ensuring a balanced distribution of soil nutrients.

A first positioning hole 19 is provided on the upper surface of the movable beam 2. A positioning bolt 8 is threadedly connected to the interior of one of the first adjustment holes 16 and the interior of the first positioning hole 19. A sliding groove 20 is provided on the right side of the crossbeam 1. A sliding seat 7 is slidably connected inside the sliding groove 20. A shallow fertilization pipe 6 is fixedly connected inside the sliding seat 7 for conveying fertilizer required for shallow fertilization. The movable beam 2... The surface is provided with symmetrical second positioning holes 21. The interior of the slide 7 is provided with several second adjustment holes 22.

The bottom end of the deep fertilizer pipe 5 and the bottom end of the shallow fertilizer pipe 6 are both fixedly connected to a diversion component 15. By cooperating with the positioning bolt 8, the first positioning hole 19 and the first adjustment hole 16, the position of the movable beam 2 on the crossbeam 1 can be adjusted, thereby adjusting the distance between the deep fertilizer pipe 5 and the shallow fertilizer pipe 6. By cooperating with the first bolt 9, the first nut 10, the second positioning hole 21 and the second adjustment hole 22, the position of the slide 7 in the slide groove 20 can be adjusted, thereby adjusting the height of the shallow fertilizer pipe 6.

[0025] Both diversion components 15 include a housing 151. The upper surfaces of the two housings 151 are connected to the bottom end of the deep fertilizer pipe 5 and the bottom end of the shallow fertilizer pipe 6, respectively. Diversion blocks 152 are fixedly connected inside the two housings 151. Flow holes 153 are opened inside the two diversion blocks 152.
