Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to a peanut rear-mounted rotary dust removal device. Background Technology

[0002] During peanut harvesting, harvesting machinery generates a large amount of debris, dust, and other impurities after digging and picking the peanuts, which are collected in the straw collection box. Existing peanut harvesting equipment typically uses simple filters or natural sedimentation to treat these impurities. However, these traditional methods have significant drawbacks. Firstly, filters are easily clogged by larger debris, leading to a significant decrease in filtration efficiency and requiring frequent shutdowns for cleaning, severely impacting operational continuity and efficiency. Secondly, natural sedimentation is ineffective at separating fine dust. During equipment operation and unloading, large amounts of dust are dispersed into the working environment by airflow, causing air pollution and posing a threat to the respiratory health of operators. Long-term exposure to high-dust environments can easily lead to occupational diseases such as pneumoconiosis. Furthermore, the dispersed dust adheres to critical equipment components, accelerating mechanical wear and increasing the risk of equipment failure and maintenance costs. Therefore, there is an urgent need for a high-efficiency and reliable dust removal device that can effectively filter and separate impurities such as broken seedlings and dust in the straw collection box, reduce dust problems during peanut harvesting, and ensure a safe working environment and stable equipment operation. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a peanut rear-mounted rotary dust collector that filters and separates impurities such as broken vines and dust from the grass collection box, thereby reducing dust generation during operation.

[0004] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a peanut rear-mounted rotary dust collector, comprising a housing, a filter module disposed inside the housing, an air inlet connection port disposed at the upper part of the housing, an impurity outlet disposed at the lower part, an air outlet pipe disposed on the outer side wall of the housing, a flow guide module disposed on the outer side of the air outlet pipe, the filter module comprising a rotating bracket, a filter cylinder disposed on the outer side of the rotating bracket, and a drive shaft extending to the outside of the housing disposed at the middle part of the rotating bracket.

[0005] As a further improvement to the above technical solution:

[0006] A sleeve for mounting a drive shaft is provided on the side wall of the housing. A drive sprocket is provided at one end of the drive shaft located outside the housing. A transmission chain that is linked to the drive shaft is provided on the drive sprocket.

[0007] The rotating bracket has a clearance hole on the side facing the air outlet pipe, and an annular sealing plate extending to the inside of the air outlet pipe is provided on the inside of the rotating bracket.

[0008] The lower end of the annular sealing plate is provided with a baffle plate that covers the impurity outlet.

[0009] The filter cartridge includes a nylon filter screen and a steel filter screen, and the rotating bracket is provided with a filter screen skeleton located inside the nylon filter screen and the steel filter screen.

[0010] The drainage module includes a mounting bracket and a fan. A drive shaft is provided in the middle of the fan, and a bearing seat for cooperating with the drive shaft is provided in the middle of the mounting bracket.

[0011] The drive shaft is equipped with a pulley, and the pulley is equipped with a drive belt that is linked to the shredder shaft.

[0012] The beneficial effects of this utility model embodiment are as follows: The peanut rear-mounted rotary dust collector includes a shell, a filter chamber inside the shell, a filter module installed inside the filter chamber, an air inlet connected to a grass collection box at the upper part of the shell, and an impurity outlet at the lower part. An air outlet pipe is installed on the outer wall of the shell, and a flow guide module is installed on the outer side of the air outlet pipe. The flow guide module provides power to guide the airflow to the air outlet pipe and then discharge it to the outside of the shell. During this process, the filter module separates impurities such as broken seedlings and soil clods and discharges them from the impurity outlet. The filter module includes a rotating bracket, and a filter cylinder arranged in a ring is installed on the outside of the rotating bracket. A drive shaft extending to the outside of the shell is provided in the middle of the rotating bracket. The drive shaft is connected to an external power source to drive the filter module to rotate, thereby completing the gas-solid separation and discharging broken seedlings and impurities from the bottom, reducing the broken seedlings and dust emitted by the self-propelled peanut harvester and reducing environmental pollution.

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-2 As shown, the peanut rear-mounted rotary dust collector of this embodiment includes a housing 1, a filter chamber inside the housing 1, a filter module installed inside the filter chamber, an air inlet 2 connected to the grass collection box at the upper part of the housing 1, and an impurity outlet 3 at the lower part. An air outlet 4 is installed on the outer wall of the housing 1, and a flow guide module is provided on the outer side of the air outlet 4. The flow guide module provides power to guide the airflow to the air outlet 4 and then discharge it to the outside of the housing 1. During this process, the filter module separates impurities such as broken seedlings and soil clods and discharges them from the impurity outlet 3. The filter module includes a rotating bracket 5, and a filter cylinder 6 arranged in a ring is installed on the outside of the rotating bracket 5. A drive shaft 7 extending to the outside of the housing 1 is provided in the middle of the rotating bracket 5. The drive shaft 7 is connected to an external power source to drive the filter module to rotate, thereby completing the gas-solid separation and discharging broken seedlings and impurities from the bottom, reducing the broken seedlings and dust emitted by the self-propelled peanut harvester and reducing environmental pollution.

[0023] The side wall of the housing 1 is provided with a sleeve 8 for mounting the drive shaft 7. The drive shaft 7 is provided with a drive sprocket 9 at one end outside the housing 1.

[0025] like Figure 5-7 As shown, the lower end of the annular sealing plate 12 is provided with a baffle plate 13 covering the impurity outlet 3. The baffle plate 13 can prevent small impurities from being driven to the air outlet 4 by the fan 18 and discharged, thus causing environmental pollution.

[0026] The filter cartridge 6 includes a nylon filter screen 14 and a steel filter screen 15. The rotating bracket 5 is provided with a filter screen skeleton 16 located inside the nylon filter screen 14 and the steel filter screen 15.
