AI Technical Summary
During use, existing fertilizer dischargers are prone to adhesion of fertilizer and their powders and form hard layer, causing the blocking wheel to get stuck and affecting the quality of fertilizer application. The soil blocks rolled up by the tractor may enter the fertilizer discharger shell through the observation hole.
A fertilizer discharger is designed, which is equipped with a transparent cover plate on the shell. The transparent cover plate is composed of a mounting shaft, an ear plate, a torsion spring and a limiting block. The transparent cover plate can be opened in one direction to prevent soil blocks from entering. At the same time, when blocked, the transparent cover plate can be automatically opened to discharge blockages.
The transparent cover not only provides a convenient viewing function, but also prevents soil blockages from entering, avoids internal blockage of fertilizer dischargers, extends service life, and automatically discharges blockages when blocked, preventing mechanical damage.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural machinery and implements, and in particular relates to a fertilizer dispenser. Background Art
[0002] At present, in actual use, fertilizers and their powders often adhere to the blocking wheel to form a hardened layer or enter the gap between the fertilizer dispensing device housing and the blocking wheel, which will cause the blocking wheel to get stuck, making the groove wheel unable to rotate at a uniform speed or stop rotating, resulting in uneven fertilization or interrupted fertilization, which seriously affects the quality of fertilization, causing crops to grow normally due to insufficient nutrients, resulting in reduced crop yields. In order to improve this defect, an observation hole is usually opened on the fertilizer dispensing device housing. Once the blocking wheel is found to be stuck, it is manually cleaned through the observation hole. However, there is a problem that the soil rolled up by the tractor will enter the fertilizer dispensing device housing through the observation hole. Therefore, a fertilizer dispensing device with anti-blocking, anti-adhesion and stable fertilizer dispensing should be provided. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a fertilizer dispensing device in view of the deficiencies in the above-mentioned prior art, which has a simple structure and a reasonable design. The transparent cover plate can not only facilitate observation, but also prevent soil rolled up by the tractor from entering the fertilizer dispensing device shell through the observation hole. When fertilizer and its powder are blocked inside the fertilizer dispensing device shell and the fertilizer dispensing port is blocked, the fertilizer and its powder can overcome the spring force of the two torsion springs, and the transparent cover plate can be opened unidirectionally from the inside of the fertilizer dispensing device shell to the outside of the fertilizer dispensing device shell, and overflow from the observation hole, which can avoid damage to the blocking wheel and the groove wheel inside the fertilizer dispensing device and help to extend the service life of the fertilizer dispensing device.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a fertilizer dispenser, characterized in that: it includes a transparent cover plate arranged on the fertilizer dispenser shell and used to block the observation hole, a mounting shaft is arranged on the top of the transparent cover plate, two ear plates are arranged on the fertilizer dispenser shell, both ends of the mounting shaft are rotatably mounted on the two ear plates respectively, both ends of the mounting shaft are arranged with torsion springs, two limit blocks are arranged at the bottom end of the transparent cover plate, and the transparent cover plate is opened unidirectionally from the inner side of the fertilizer dispenser shell to the outer side of the fertilizer dispenser shell.
[0005] The above-mentioned fertilizer dispenser is characterized in that the thickness of the transparent cover plate ranges from 5 mm to 10 mm.
[0006] Compared with the prior art, the utility model has the following advantages:
[0007] 1. The utility model provides a transparent cover plate for blocking the observation hole on the housing of the fertilizer dispensing device, and provides a mounting shaft at the top of the transparent cover plate, so that the transparent cover plate is rotatably connected to the two ear plates of the housing of the fertilizer dispensing device through the mounting shaft. In actual use, the fertilizer dispensing device is usually in a very bumpy working environment driven by a tractor or a seed drill. Therefore, torsion springs are provided at both ends of the mounting shaft, and the transparent cover plate can be in a closed state under the action of the two torsion springs. At this time, the transparent cover plate can not only facilitate observation, but also prevent the soil rolled up by the tractor from entering the housing of the fertilizer dispensing device through the observation hole. When the housing of the fertilizer dispensing device is clogged with fertilizer and its powder, and the fertilizer dispensing port is blocked, the fertilizer and its powder can overcome the spring force of the two torsion springs, and the transparent cover plate can be opened unidirectionally from the inner side of the housing of the fertilizer dispensing device to the outer side of the housing of the fertilizer dispensing device, and overflow from the observation hole, so that the blocking wheel and the groove wheel inside the fertilizer dispensing device can be prevented from being damaged, which helps to extend the service life of the fertilizer dispensing device.
[0008] 2. The utility model sets two limit blocks at the bottom end of the transparent cover plate, and one end of the two limit blocks is placed on the outer surface of the fertilizer dispensing device shell. The two limit blocks can limit the opening direction of the transparent cover plate, that is, the transparent cover plate can only be opened from the inner side of the fertilizer dispensing device shell to the outer side of the fertilizer dispensing device shell, and cannot be opened from the outer side of the fertilizer dispensing device shell to the inner side of the fertilizer dispensing device shell.
[0009] 3. The utility model has a simple structure, reasonable design, low manufacturing cost and is easy to promote and apply.
[0010] In summary, the utility model has a simple structure and a reasonable design. The transparent cover plate not only facilitates observation, but also prevents soil rolled up by the tractor from entering the fertilizer dispensing device shell through the observation hole. When fertilizer and its powder are blocked inside the fertilizer dispensing device shell and the fertilizer discharge port is blocked, the fertilizer and its powder can overcome the spring force of the two torsion springs, and the transparent cover plate can be opened unidirectionally from the inside of the fertilizer dispensing device shell to the outside of the fertilizer dispensing device shell, and overflow from the observation hole, which can avoid damage to the blocking wheel and the groove wheel inside the fertilizer dispensing device and help to extend the service life of the fertilizer dispensing device.
