Description

Technical Field

[0001] The utility model relates to the technical field of peanut harvesting, and in particular to a water-filtering environmentally friendly smoke and dust treatment device. Background Art

[0002] At present, the comprehensive mechanization level in my country has reached 97.7%. The widespread application of peanut harvesting mechanization technology has greatly improved agricultural production efficiency and quality on the one hand, but has also caused dust pollution problems on the other. In order to further strengthen the dust control of agricultural machinery operations, protect and improve the environment, in line with the principle of "combining long-term and short-term, treating both the symptoms and the root causes, relying on science and technology, and solving the root causes", it is necessary to add dust reduction devices to large harvesting machinery, mainly peanut harvesters. The dust reduction method commonly used by existing peanut harvesters is to add dust reduction bags at the air outlet of the peanut harvester, and use the dust reduction bags to filter the exhaust gas. However, in actual use, the dust reduction bags are often separated from the air outlet due to too much internal debris, causing secondary pollution.

[0003] In order to solve the above problems, the existing patent CN117694084A proposes a dust reduction device and method for a peanut picking machine, which includes a frame and an upper body system, an air intake system, a decompression dust reduction chamber and a lower body system arranged on the frame; the air intake system includes an air intake port, an air chamber, a filter and an air supply pipe, a filter is arranged below the air chamber, an air intake port is arranged at the upper part of the air chamber, and an air supply pipe is arranged at the lower part; the upper body system includes an upper body port and an air intake port of the air intake system; the decompression dust reduction chamber is provided with a bubble spray system, a water spray system and a decompression dust reduction system, and the top of the decompression dust reduction chamber is connected to the upper body port The peanut picking and fruit picking machine is connected to the system, and the bottom is connected to the lower system of the machine body; the exhaust port of the peanut picking and fruit picking machine is connected to the upper system of the machine body, and the exhaust port of the peanut picking and fruit picking machine is respectively connected to the upper body and the air intake port, and the air intake port introduces part of the wind exhausted by the peanut picking and fruit picking machine into the wind chamber, which is filtered by the filter in the wind chamber and then delivered to the fruit cleaning fan of the peanut picking and fruit picking machine through the air supply pipe for secondary utilization of wind energy, which can reduce the power of the fruit cleaning fan and save energy and reduce consumption; the wind entering the upper port of the machine body is sprayed by the bubble spray system and then enters the pressure reduction and dust reduction chamber, and is discharged through the lower system of the machine body after being processed by the water spray system and the pressure reduction and dust reduction system.

[0004] Although the device can suppress dust to a certain extent, it consumes a large amount of water resources in actual use. The driver needs to add water repeatedly to ensure the dust suppression operation, which is rather cumbersome and affects the operation progress of the peanut harvester. In addition, the water resources cannot be recycled. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0024] like Figures 1 to 4 As shown, a water-filter environmentally friendly smoke dust treatment device is mainly composed of a frame 1 and a high-pressure fan 3. A storage box 2 is arranged on the upper part of the frame 1, and a docking air inlet 201 is obliquely arranged on the upper part of one side of the storage box 2. The storage box 2 is docked with the air outlet of the peanut harvester through the docking air inlet 201; a docking air outlet 202 is arranged on the upper part of the other side of the storage box 2, and the storage box 2 is docked with the air inlet of the high-pressure fan 3 through the docking air outlet 202.

[0025] The storage box 2 is provided with a debris blocking mechanism, which is used to screen out large areas of ground film or weeds in the smoke and dust discharged by the peanut harvester.

[0026] The debris blocking mechanism is composed of a debris blocking screen 8, a cleaning brush 16 and a transmission component, etc. The debris blocking screen 8 is installed at the connection between the air inlet and the docking port of the high-pressure fan 3;

[0027] The transmission assembly consists of a transmission shaft 10, a transmission shaft 18, a driving sprocket 15, a driven sprocket 17 and a transmission chain 11. A driving motor 9 is installed on the top of the storage box 2. The output end of the driving motor 9 is connected to the transmission shaft 10. The transmission shaft 10 is installed on the top of the storage box 2 through a bearing seat, and driving sprockets 15 are respectively installed at both ends of the transmission shaft 10; the storage box 2 is connected to the transmission shaft 18 for transverse rotation inside, and driven sprockets 17 are arranged at both ends of the transmission shaft 18 corresponding to the position of the driving sprocket 15 on the transmission shaft 10. Each driving sprocket 17 is connected to its corresponding driven sprocket 17 through the transmission chain 11. The driving motor 9 drives the transmission shaft 10 to rotate, so that the driving sprocket 15 drives the driven sprocket 17 to rotate through the transmission chain 11.

[0028] At least two cleaning brushes 16 are arranged transversely between the two transmission chains, and there is a certain interval between the two cleaning brushes 16. When the cleaning brushes 16 are installed, the bristles of the cleaning brushes 16 are in close contact with the debris screen curtain 8, ensuring that the cleaning brushes 16 can remove large pieces of mulch or weeds on the debris screen curtain 8, so that the air duct of the debris screen curtain 8 remains unobstructed.

[0029] The frame 1 is located below the storage box 2 and is also provided with a dust removal mechanism, which consists of a purification chamber 4, a water storage tank 7 and a sewage centrifuge 5. A dust inlet is provided on the lower part of the side wall of the purification chamber 4 on the same side as the air outlet 202 on the storage box 2, and the air outlet of the high-pressure fan 3 is connected to the dust inlet; a sewage outlet 402 is provided at the bottom of the purification chamber 4, and a valve is provided on the sewage outlet 402.

[0030] A stirrer 13 is also installed horizontally inside the purification chamber 4. The stirrer 13 consists of a stirring shaft and a spiral stirring blade placed on the stirring shaft. One end of the stirring shaft extends to the outside of the purification chamber 4 and is connected to a driving motor 14 through a belt drive; a double-layer filter mesh 401 is arranged on the upper part of the purification chamber 4, and a clean air outlet is arranged above the double-layer filter mesh 401 in the purification chamber 4.

[0031] A sewage pump 6 is installed below the purification chamber 4. In the present embodiment, the sewage pump 6 is a horizontal sewage pump. A discharge port is provided at the bottom of the purification chamber 4. The feed port of the sewage pump 6 is connected to the discharge port of the purification chamber 4. The discharge port of the sewage pump 6 is connected to the sewage inlet 503 at the top of the sewage centrifuge 5. The sewage is delivered to the sewage centrifuge 5 through the sewage pump 6.

[0032] The sewage centrifuge 5 is composed of a housing 501 and a conical screen 502 rotatably connected inside the housing 501. A sewage inlet 503 is provided on the top of the housing, and the sewage in the sewage pump 6 enters the conical screen 502 through the sewage inlet 503; a water outlet 504 is provided at the bottom of the side wall of the housing 501, and the water outlet 504 is connected to the purification chamber 4 through a water pipe. The sewage entering the sewage centrifuge 5 is separated from the water and solid debris by the centrifugal action of the conical screen 502, and the dehydrated solid debris is uniformly discharged, and the filtered water enters the purification chamber 4 for recycling.

[0033] In this embodiment, the power source of the agitator 13, the sewage pump 6 and the sewage centrifuge 5 can be the drive motor 2 14, which is placed at the bottom of the housing of the sewage centrifuge 5, and the output end of the drive motor 2 14 is connected to the dual-output reducer, one output end of the dual-output reducer is fixedly connected to the bottom of the conical screen 52, and the other output end of the dual-output reducer motor provides power to the agitator shaft and the sewage pump 6 through belt transmission. The power source of the high-pressure fan 3 can be provided by the drive motor of the peanut harvester through belt transmission.

[0034] A water storage tank 7 is also installed on one side of the frame 1. The water storage tank 7 is connected to the purification chamber 4 through a water supply pipe. A water level control valve 12 is installed on the pipe mouth of the water supply pipe located in the purification chamber 4. The water level control valve 12 is used to realize automatic water replenishment from the water storage tank 7 to the inside of the purification chamber 4. In this embodiment, the water level control valve 12 is an existing commercially available product and can be a float valve.

[0035] When the device is used for dust suppression of a peanut harvester, after the pneumatic operation of the peanut harvester in the farmland starts, a large amount of dust will be generated in the process of picking up, removing fruits and peeling seedlings. The seedling and fruit peeling screening is mainly completed by the fan on the peanut harvester. At this time, the fan blows out a large amount of dust. Under the action of the high-pressure fan, the dust is introduced into the purification chamber 4 through the docking air inlet 201 at the top of the storage box 2 through the impurity screen 8. When the smoke passes through the impurity screen 8, larger impurities such as ground film and weeds are screened by the impurity screen 8. The cleaning brush 16 scrapes the impurities attached to the impurity screen 8 into the storage box 2 for centralized discharge under the circulation operation of the transmission chain 11, ensuring that large volumes of ground film, weeds, etc. do not enter the subsequent equipment;

[0036] The smoke dust passing through the impurity screen 8 is converted into high-pressure gas by the high-speed operation of the high-pressure fan and sent to the purification chamber 4 for filtration. Under the action of the agitator 13 in the purification chamber 4, the smoke dust and the water in the purification chamber 4 are fully integrated. The integrated sewage is pumped into the sewage centrifuge 5 through the sewage pump 6 for centrifugal separation, and the gas after the water filtration is discharged after secondary purification through the double-layer filter material net 401 on the upper part of the purification chamber 4;

[0037] After the sewage enters the sewage centrifuge 5, the conical screen 502 rotates at high speed to separate the sewage into solid and liquid. The clean water under the conical screen 502 is sent into the purification chamber 4 through the water outlet on the shell 501, and the solid debris on the conical screen 502 is discharged from the bell mouth of the conical screen 502.

[0038] The main function of the water storage tank 7 is to replenish water into the purification chamber 4. When the liquid level in the purification chamber 4 is lower than the set value of the water level control valve 12, the water level control valve 12 automatically opens to replenish water into the purification chamber 4. When the liquid level in the purification chamber 4 is higher than the set value of the water level control valve 12, the water level control valve 12 automatically closes and stops replenishing water.

[0039] The device is connected to the air outlet of the peanut harvester, and filters the smoke and dust emitted by the peanut harvester by means of water filtration and dust reduction, thereby solving the problem of smoke and dust emission from the root, and separating the solid and liquid of the sewage after water filtration, and the separated water is sent back to the purification room for reuse, thereby improving the utilization rate of water resources.

[0040] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
