Description

Technical Field

[0001] The utility model relates to a fertilizer unit, in particular to a pneumatic conveying fertilizer unit, belonging to the technical field of fertilizer application. Background Art

[0002] With the development of agricultural modernization, the demand for agricultural production efficiency is becoming increasingly higher. Traditional mechanical fertilization devices have poor fertilizer discharge accuracy and low efficiency, and cannot meet the needs of high-speed, high-efficiency mechanized fertilization. Pneumatic fertilization unit technology uses positive high-pressure airflow to transport fertilizer, which can quickly and accurately blow fertilizer into the soil, ensuring the accuracy and efficiency of fertilizer discharge and meeting the requirements of high-speed operation.

[0003] In the existing technology, most fertilizer discharge devices use a groove wheel structure for fertilizer discharge. Due to its structural limitations, the amount of fertilizer applied is mainly limited by the rotation speed, making it difficult to ensure fertilization accuracy and fertilizer discharge efficiency. The double-furrowing disc structure fertilizer unit is prone to soil entering the disc and straw being blocked at the meshing angle, leading to problems such as the furrowing disc stopping and the pile being dragged. In addition, the current fertilizer unit fertilizer discharge pipes are mostly circular I-shaped. When the soil viscosity is high, the fertilizer discharge pipe outlet is easily blocked, causing fertilizer accumulation. To this end, we provide a pneumatic conveying fertilizer unit to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a pneumatic conveying fertilizer unit in order to solve the above problems, so as to solve the problems in the prior art that the fertilization accuracy and efficiency cannot be guaranteed, soil is easily entered into the pan, and fertilizer is easily blocked and accumulated.

[0005] The utility model is realized by the following technical solutions: a pneumatic conveying fertilizer unit, comprising a furrowing disc assembly, a seeding tube assembly and a suspension assembly, wherein the furrowing disc assembly, the seeding tube assembly and the suspension assembly are mutually connected and fixed by bolts;

[0006] The furrowing disc assembly includes a spherical furrowing disc and a sealing cover, and the furrowing disc and the sealing cover are fixedly connected by bolts. The seed tube assembly includes an air discharge plate, a fertilizer inlet pipe and a fixed plate, and the air discharge plate, the fertilizer inlet pipe and the fixed plate are fixedly connected by welding. The furrowing disc assembly, the seed tube assembly and the suspension assembly are interconnected to form a core frame, and the furrowing disc assembly, the seed tube assembly and the suspension assembly are interconnected by bolts, thereby facilitating subsequent disassembly and maintenance work by subsequent staff.

[0007] Preferably, the ditching disc assembly includes a bearing seat, a bearing and a fixed shaft, and the bearing seat, bearing and fixed shaft are fixedly connected to the spherical ditching disc by means of bolts for breaking soil and ditching.

[0008] Preferably, the seeding pipe assembly includes a fertilizer outlet trough plate and a fertilizer outlet cover plate, and the fertilizer outlet trough plate and the fertilizer outlet cover plate are fixedly connected by welding. The inclined fertilizer outlet square pipe of the seeding pipe assembly is connected to the fertilizer inlet pipe, and pneumatic transportation of fertilizer is achieved through high-pressure airflow.

[0009] Preferably, the suspension assembly includes a suspension arm and a scraper plate, which are fixedly connected by bolts. The scraper plate has a curvature radius R of mm-mm, an inclination angle α of °-°, and a length L of mm-mm. It is used to scrape off the soil adhered to the spherical furrowing disc and form soil-breaking protection for the fertilizer square pipe.

[0010] Preferably, the outer surface of the scraper plate is arranged to form a fan-shaped angle with the spherical furrowing disc, and the cooperation between the spherical furrowing disc and the scraper plate increases the contact length of the engagement angle, thereby preventing soil and straw from entering the interior of the furrowing disc.

[0011] Preferably, the fertilizer trough plate and the fertilizer discharge cover plate are fixed by welding to form a fertilizer discharge square tube, and the connection between the fertilizer trough plate and the fertilizer discharge cover plate is made more secure by welding.

[0012] Preferably, the fixed shaft of the ditching disc assembly is connected to the fertilizing unit frame by bolts, and the fixed shaft effectively fixes the ditching disc assembly.

[0013] The utility model provides a pneumatic conveying fertilizer unit, which has the following beneficial effects:

[0014] 1. Simple structure. The pneumatic conveying fertilizer unit is composed of only three parts. Compared with the traditional fertilizer unit, the structure has been greatly simplified.

[0015] 2. It has good fertilization accuracy and discharge efficiency. After the traditional fertilizer unit is discharged by the fertilizer discharge device, most of the fertilizer falls into the fertilizer ditch in a free fall state, which makes it difficult to achieve high-speed operation. In addition, during the falling period, fertilizer floating will occur, and the fertilization accuracy and discharge efficiency are difficult to guarantee. After the pneumatic conveying fertilizer unit is transported by high-pressure airflow, the fertilizer is forced to be thrust, which greatly improves the fertilization accuracy and discharge efficiency.

[0016] 3. It can prevent the trenching disc from stalling, dragging piles and other problems. The coordination between the spherical trenching disc and the scraper blade increases the contact length of the meshing angle, making it difficult for soil and straw to enter the trenching disc.

[0017] 4. The outlet of the fertilizer pipe is not easy to be blocked. The pneumatic fertilization unit is a combination of oblique fertilizer delivery and high-pressure airflow, which can effectively blow away the debris at the outlet. In addition, an air discharge plate is provided to prevent fertilizer choking and ensure that the fertilizer is evenly spread.

[0018] 5. It is convenient to carry out wide multi-row operations. The pneumatic conveying fertilization unit is not restricted by the fertilizer box structure and can realize long-distance transportation of fertilizer. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The component structures shown in the accompanying drawings are intended to provide conceptual reference diagrams. Their presentation forms and interrelationships provide a basic framework for understanding the overall design intent. It should be emphasized that these diagrams are not finalized rigid templates.

This mainly includes fully considering the core functional requirements of specific application scenarios, strictly evaluating the physical limitations of actual assembly, and strictly referring to the current material properties, manufacturing process levels and cost control requirements. Therefore, the geometric parameters, key dimensions and material specifications of the components need to be systematically reviewed and revised to ensure that the parameters achieve the optimal balance between theoretical feasibility and engineering practicality.
