Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment used for environmentally friendly treatment of crop straws, and in particular relates to a traction-type environmentally friendly straw burning and returning machine to the field. Background Art

[0002] With the rapid development of agricultural modernization, agricultural grain and crop output has increased year by year. At the same time, a large amount of grain and other crop straw has been produced. The large amount of straw produced in the same season cannot be fully utilized in a short period of time. If it is used for papermaking, it is easy to pollute the environment, and the resulting pollution treatment costs are far greater than the output ratio; if it is used for power generation, the combustion value is too low, wasting a lot of manpower and material resources; if it is used as feed, its demand is far less than the supply chain. At present, the effective treatment method is to burn crop straw in an environmentally friendly manner and return the products after combustion to the arable land.

[0003] Due to the lack of more environmentally friendly burning solutions, the burning of crop straw can only rely on manual burning by farmers at this stage. This burning method will cause serious air pollution. The PM2.5 particles in the air will seriously exceed the standard, causing serious harm to people's health. At the same time, it will lead to an increase in the incidence of lung cancer. The smoke produced by the unlimited burning of straw has caused many traffic accidents on the road. In windy weather, it is very easy to cause fires, and even seriously affect the normal take-off and landing of civil aviation aircraft, thereby affecting people's normal travel.

[0004] In addition, since the compaction phenomenon of rural land is very serious at present, there is an urgent need for an environmentally friendly straw burning and returning device to the field, which can not only burn the insect eggs in the straw, but also ensure that the smoke and dust after burning the straw meet the emission standards, and the wood ash after burning the straw can be directly returned to the field, so that the compacted land can be restored and improved year by year. Summary of the invention

[0005] In view of the defects existing in the above-mentioned prior art, the present invention discloses a traction-type straw environmentally friendly burning and returning machine to the field, which can burn crop straw and kill insect eggs in the straw. The gas after burning reaches the emission standard and is discharged into the atmosphere.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The towed straw environmentally friendly burning and returning machine of the present invention has an independent combustion chamber, which is relatively closed to ensure full combustion of the straw and avoid overflow of combustion gas. The ends are provided with cutting discs on both sides to cut off the messy straw outside the combustion chamber, and the combustion chamber is always kept in an independent space. A two-way steel wire auger is provided inside the combustion chamber, which can move the straw backward and gather the straw to the middle at the same time, which is more conducive to the burning of the straw in the combustion chamber.

[0034] 3. The towed straw environmentally friendly burning and returning machine of the present invention meets the environmental protection requirements in the treatment of smoke generated by combustion. After the smoke from burning the straw enters the smoke filter filled with water, it passes through one or more layers of air filter screens, and then passes through counter-rotating stirring grid wheels to accelerate the dissolution and filter out the smoke. At the same time, the air is transformed into bubble water, and then passes through one or more layers of intercoolers to perform secondary cooling on the smoke. The air with the smoke is filtered through one or more intercoolers and discharged into the atmosphere. At the same time, external air enters the intercooler to cool the water in the smoke filter to ensure smooth smoke filtration.

[0035] 4. The towed straw environmentally friendly burning and returning machine of the present invention meets environmental protection requirements in treating the dirt generated by filtering smoke. The water in the smoke filter will become turbid after long-term filtration. At this time, the sewage separator is started, and the cage rotates and cooperates seamlessly with the filter screen to take out the dirt and other debris and return them to the cultivated land. The separated clean water flows back into the filter above the smoke filter for water filtration again. Multiple filtering cycles and cooling are performed to ensure the purity of the water to facilitate filtering smoke and heat dissipation.

[0036] 5. The traction-type environmentally friendly straw burning and returning machine to the field described in the present invention is provided with a lifting cylinder and a lifting wheel. When not in operation, the lifting wheel swings downward under the action of the lifting wheel cylinder to lift the entire combustion chamber off the ground, and the machine is pulled by a tractor to move; when in operation, the lifting wheel swings upward under the action of the lifting wheel cylinder to place the combustion chamber on the ground, and the machine is pulled forward by a tractor to cover the straw in the combustion chamber, stop the machine and ignite the fire. When the fire is big, start the fan, and then move forward, burning while walking. The operation is simple and convenient.

[0037] 6. The towed straw burning and returning machine for environmentally friendly use of the present invention has a rotary tiller installed at the rear end. Since the vehicle is constantly moving forward during the burning process, the rotary tiller 14 installed at the rear plows the field into ridges at the same time, which is convenient for sowing.

[0067] The smoke generated after the burning of the straw in the combustion chamber 1 will be sucked out through the smoking port at the front end of the combustion chamber 1 and will flow out through the cooling hood 18. In order to prevent the broken straw fragments from being sucked into the cooling hood 18 and then blocking the downstream ventilation pipe, an arc-shaped smoking port filter 41 is provided at the smoking port at the front end of the combustion chamber 1. At the same time, in order to prevent the filtered debris from blocking the smoking port filter, a two-way auger 25 made of steel wire is provided at the rear end of the smoking port filter 41. As the two-way auger 25 rotates, the straw dust or straw fragments and other debris attached to the smoking port are transported to the axial ends of the two-way auger 25 and then transported to the combustion chamber 1 for secondary combustion. In addition, a cutting disc 16 is provided at the left and right ends of the front end of the combustion chamber 1, respectively. The cutting disc 16 is used to cut off the messy straw or weeds outside the combustion chamber 1, so as to always keep the combustion chamber 1 in a relatively independent working space.

[0068] A traction frame 17 is welded and fixed at the front end of the combustion chamber 1, and the traction-type environmentally friendly straw burning and returning machine of the present invention is connected to a traction power vehicle (such as a tractor) through the traction frame 17;

[0069] Lifting wheels 30 are swingably connected to the left and right side walls of the combustion chamber 1 through connecting rods, and a combustion chamber lifting wheel cylinder 29 is installed between the lifting wheel 30 and the side wall of the combustion chamber 1. The lifting wheel 30 is driven to swing up and down relative to the combustion chamber 1 by controlling the extension and contraction of the combustion chamber lifting wheel cylinder 29; wherein: when the combustion chamber 1 is not working, under the action of the combustion chamber lifting wheel cylinder 29, the lifting wheel 30 swings downward to lift the entire combustion chamber 1 off the ground, and the combustion chamber 1 is pulled forward by a tractor; when the combustion chamber 1 is working, under the action of the combustion chamber lifting wheel cylinder 29, the lifting wheel 30 swings upward to place the combustion chamber 1 on the ground, and the combustion chamber 1 is pulled forward by a tractor, and the straw to be burned is covered in the combustion chamber 1, the car is stopped and ignited, and when the fire is large, the corresponding fan in the fan pipeline is started, and then the car moves forward, burning while walking;

[0079] The smoke filter assembly includes: a smoke filter tube 7 located at the bottom of the smoke filter housing 9, a filter screen 42, a bubble stirring mechanism and a filter 11 located at the top of the smoke filter housing 9; wherein, the two ends of the smoke filter tube 7 are welded and fixed to the two inner side walls at the bottom of the smoke filter housing 9, and the circumferential surface of the smoke filter tube 7 is provided with uniform smoke filter holes, and the smoke generated by the combustion in the combustion chamber 1 will pass through the smoke exhaust hood 18, the smoke pipe 19, the smoke exhaust fan 2 and the smoke exhaust air duct 6 in sequence, and then enter the interior of the smoke filter housing 9 through the smoke filter tube 7, and the smoke enters the water inside the smoke filter housing 9 through the smoke filter holes on the smoke filter tube 7; the filter The air screen 42 is arranged above the smoke filter tube 7, and the outer edge of the air filter screen 42 is connected to the inner wall of the smoke filter housing 9.

Under the stirring of the clockwise stirring grid wheel 43 and the counterclockwise stirring grid wheel 44 rotating in opposite directions, the bubbles are evenly stirred into smaller bubbles, making it easier to fully dissolve in water and then cooled by the intercooler 28.

[0080] In this embodiment, the bubble stirring mechanism is arranged and installed between two layers of air filter screens 42, and is composed of a clockwise stirring grid wheel 43, a counterclockwise stirring grid wheel 44, a rotary motor 45, a stirring assembly fixing frame 46 and a planetary gear train mechanism 47; wherein the planetary gear train mechanism 47 includes a sun gear, a planetary gear, a planetary carrier and a ring gear; the stirring assembly fixing frame 46 is fixedly installed on the inner wall of the smoke filter housing 9, the rotary motor 45 is vertically installed on the stirring assembly fixing frame 46, the output shaft of the rotary motor 45 is coaxially connected to the sun gear of the planetary gear train mechanism 47, and the planetary carrier of the planetary gear train mechanism 47 is connected to the stirring The mixing assembly fixing frame 46 is fixedly connected, the planetary gear of the planetary gear train mechanism 47 is rotatably mounted on the planetary frame, the inner side of the planetary gear is meshed and connected to the sun gear, and the outer side of the planetary gear is meshed and connected to the ring gear of the planetary gear train mechanism 47, the sun gear is coaxially fixedly connected to the reverse mixing grid wheel 44, and the ring gear is coaxially fixedly connected to the clockwise mixing grid wheel 43.
