Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and more specifically, to a tracked, new energy, unmanned straw harvesting, crushing, and fertilizer-making integrated machine. Background Technology

[0002] Straw is a general term for the stems and leaves of mature crops, usually referring to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops after the grains are harvested. More than half of the products of crop photosynthesis are found in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a renewable biological resource with multiple uses.

[0003] Mechanized direct straw return to the field involves uniformly crushing straw and allowing it to decompose in the soil to form organic nutrients. However, during the straw return process, the straw decomposes slowly in the soil, making it difficult to quickly turn into fertilizer. This can affect the planting of the next season's crops. Straw takes a long time to turn into fertilizer, and the high temperatures generated during the process can cause root burn and seedling death. It can also lead to severe soil acidification and compaction. Straw return to the field can damage the soil structure, and the nutrients required for straw decomposition and fermentation can easily lead to a decline in soil fertility, affecting normal seed germination. Straw return to the field also directly returns weed seeds and insect eggs to the field, forcing farmers to use large amounts of pesticides, insecticides, and chemical fertilizers. This not only increases agricultural production costs but also raises food safety issues.

[0004] Utility model patent CN221812680U discloses a tracked straw harvesting, crushing, and fertilizer-making integrated machine, including a walking device, a base, a feeding and harvesting device, a crushing device, a driver's cab, a feeding device, and a mixing chamber. The walking device is fixedly installed under the base, and the mixing chamber is fixedly installed on the base. The crushing device is fixedly connected to the feeding and harvesting device through the feeding device. The feeding and harvesting device is fixedly installed on one side of the base, and the driver's cab is also fixedly installed on the base. While collecting straw, the machine cuts and crushes the long stubble left after harvesting and sprays it into the mixing chamber. Fermentation bacteria are automatically added, and water is automatically added at appropriate levels to complete the fertilizer production.

[0005] Although this machine can crush straw and add biological inoculants to make fertilizer, when the machine harvests straw, some soil is carried into the mixing chamber. When the soil content is high, it will affect the overall moisture of the straw. In addition, the soil contains a large number of native microorganisms. These microorganisms will compete with the added fermentation functional inoculants for organic matter and oxygen in the straw, which will inhibit the activity of the functional inoculants and greatly reduce the fermentation efficiency. Summary of the Invention

[0006] This invention provides a tracked, new energy, unmanned straw harvesting, crushing, and fertilizer-making integrated machine. It uses a filter grid to separate large clumps of soil, and then, in conjunction with a primary crushing component, crushes both the straw and soil, discharging the crushed soil outwards. This solves the problems mentioned in the background art, namely: when harvesting straw, the straw carries some soil into the mixing chamber. A high soil content affects the overall moisture content of the straw, and the soil contains a large number of indigenous microorganisms. These microorganisms compete with added fermentation functional bacteria for organic matter and oxygen in the straw, inhibiting the activity of the functional bacteria and significantly reducing fermentation efficiency.

[0007] To achieve the above objectives, a tracked new energy unmanned straw harvesting, crushing, and fertilizer-making integrated machine is provided, comprising a new energy unmanned walking frame, a tracked chassis detachably connected to the bottom of the new energy unmanned walking frame, an adjustable support arm installed on one side of the new energy unmanned walking frame, a harvesting bucket detachably connected to the end of the adjustable support arm, a mixing chamber provided on the new energy unmanned walking frame, a discharge gate panel provided on the side wall of the new energy unmanned walking frame, and a primary crushing component provided on one side of the mixing chamber, the primary crushing component including a conveying track, a conveying auger, crushing teeth, and a second... A servo motor and a conveying auger are rotatably connected inside the conveying track. Each blade of the conveying auger has multiple crushing teeth on its outer wall. A second servo motor is detachably connected to the outside of the new energy unmanned vehicle frame. The rotating end of the second servo motor is inserted into the new energy unmanned vehicle frame and detachably connected to one end of the conveying auger. A filter screen is installed at the bottom of the conveying track. The interior of the new energy unmanned vehicle frame below the filter screen is connected to the outside. The crushed soil is discharged downward through the filter screen. The crushing teeth apply shear force to the straw as they rotate, crushing the straw.

[0008] In the above technical solution, by setting the crushing teeth, the crushing teeth can apply shear force to the straw and soil as they rotate during the straw conveying process. By setting the filter screen, the crushed soil is discharged downward through the filter screen, thereby reducing the amount of soil residue on the straw inside the mixing chamber.

[0009] Based on this, guide slopes are set on both sides of the upper end of the conveying track, and raised ridges are set on the outer wall of each blade of the conveying auger rod. The ridges can generate a kneading force on the straw during the conveying process.

[0010] In the above technical solution, the setting of the guide slope allows the cut straw to better contact the conveying auger rod, and the ridges can generate a kneading force on the straw during the conveying process.

[0011] Based on this, a fan-shaped rotating plate is detachably connected to the rotating end of the second servo motor. A U-shaped bracket is detachably connected to the bottom inner side of the new energy unmanned walking vehicle frame on the conveying track. A striking rod is rotatably connected inside the U-shaped bracket. A rubber striking head is fixedly connected to the end of the striking rod near the conveying track, and a rotating shaft is rotatably connected to the end of the striking rod away from the conveying track. The rotation of the conveying auger rod drives the fan-shaped rotating plate to rotate. During the rotation, the fan-shaped rotating plate will contact the rotating shaft, causing the rubber striking head to tilt upward and strike the conveying track, causing the conveying track to vibrate.

[0012] In the above technical solution, the rotating conveyor auger rod drives the fan-shaped rotating plate to rotate. During the rotation, the fan-shaped rotating plate will contact the rotating shaft, causing the rubber striking head to tilt upwards and strike the conveyor track, thereby causing the conveyor track to vibrate and assist in the discharge of soil.

[0013] Based on this, a blowing assembly is installed inside the new energy unmanned vehicle frame above the conveying track. The blowing assembly blows air onto the conveying track, causing the crushed soil to fall downwards. The blowing assembly includes a blowing trough plate, an air inlet pipe, and a blower. The blowing trough plate is located above the conveying track. The air inlet pipe is connected to the blowing trough plate, and its other end extends out of the new energy unmanned vehicle frame and is detachably connected to the air inlet of the blower. The blower is detachably connected to the outside of the new energy unmanned vehicle frame.

[0014] In the above technical solution, the air outlet of the air trough plate blows towards the conveying track, causing the soil to be discharged through the opening at the bottom of the conveying track that connects to the outside during the flying process, and can also assist the soil to fall downwards.

[0015] Based on this, a filter grid plate is detachably connected to the inner wall of the harvester near the outside. The straw passes through the grooves between the filter grid plates, and large pieces of soil are peeled off the straw.

[0016] In the above technical solution, during the straw harvesting process, the straw passes through the grooves between the filter grid plates, thereby enabling the removal of larger clumps of soil.

[0017] Based on this, the upper end of the mixing chamber is detachably connected to an installation cover plate, on which a mixing component is installed. The mixing component mixes the crushed straw. A humidifying component is installed on the installation cover plate, which sprays water to humidify the straw so that the straw's humidity meets the standard. A microbial inoculation component is installed on the installation cover plate, which sprinkles biological inoculants into the interior of the straw.

[0018] The mixing assembly includes a mixing rod, a mixing and pulverizing blade, and a first servo motor. The first servo motor is detachably connected to the upper end of the mounting cover plate. The rotating end of the first servo motor passes through the mounting cover plate and is detachably connected to the end of the mixing rod. The mixing and pulverizing blade is fixedly connected to the outer wall of the mixing rod. There are multiple mixing and pulverizing blades.

[0019] The microbial inoculation component includes a microbial inoculum chamber and an inoculation ring. The microbial inoculum chamber is detachably connected to the upper end of the mounting cover plate, and the inoculation ring is detachably connected to the bottom of the mounting cover plate. The microbial inoculation device has a built-in power component, which transports the microbial inoculum inside the microbial inoculum chamber to the interior of the mixing chamber through the inoculation ring to mix with the straw.

[0020] The humidification component includes a water storage tank and a spray head. The water storage tank is detachably connected to the upper end of the mounting cover, and the spray head is detachably connected to the lower end of the mounting cover. The spray head has a built-in water pump. The inlet of the water pump is connected to the inside of the water storage tank, and the outlet of the water pump is connected to the spray head. The spray head is located on the side near where the straw enters the mixing chamber.

[0021] Based on this, the inside of the adjustable support arm is equipped with a conveying channel, and the bottom of the inner side of the conveying channel is detachably connected to a conveying component. The conveying component conveys the straw, and a reciprocating shearing machine is detachably connected to the inner wall of the new energy unmanned walking vehicle frame near the conveying component.

[0022] In the above technical solution, the reciprocating shearing of the reciprocating shearing machine can cut long straw into smaller pieces, making it easier to transport, mix and make fertilizer.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] In this tracked new energy unmanned straw harvesting, crushing and fertilizer production machine, the filter grid plate of the harvesting bucket can separate large pieces of soil from the roots of the straw. The primary crushing component can crush the straw and soil. The filter screen plate at the bottom can discharge the fine soil powder generated during the crushing process. Then, the soil discharge is assisted by the tapping and vibration conveying track, and the design of blowing and dust suppression effectively reduces the soil residue in the straw and avoids the soil affecting the fermentation of the straw in the fertilizer production process.

[0040] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] When straw is harvested, it carries some soil into the mixing chamber. If the soil content is high, it will affect the overall moisture content of the straw. In addition, the soil contains a large number of native microorganisms. These microorganisms will compete with the added fermentation functional bacteria for organic matter and oxygen in the straw, which will inhibit the activity of the functional bacteria and significantly reduce the fermentation efficiency.

[0042] Therefore, in view of the above-mentioned problems, the present invention discloses a tracked new energy unmanned straw harvesting, crushing and fertilizer production integrated machine, such as... Figure 1-4 As shown, the system includes a new energy unmanned vehicle frame 100. A tracked chassis 101 is detachably connected to the bottom of the new energy unmanned vehicle frame 100. An adjustable support arm 102 is installed on one side of the new energy unmanned vehicle frame 100, and a harvesting bucket 103 is detachably connected to the end of the support arm 102. A mixing chamber 200 is installed on the new energy unmanned vehicle frame 100, and a discharge gate 105 is installed on the side wall of the new energy unmanned vehicle frame 100. In this embodiment, the new energy unmanned vehicle frame 100 is driven to move in the field by the tracked chassis 101. Compared with the traditional wheeled movement method, this increases the contact area with the ground and reduces damage to the soil. The harvesting bucket 103 harvests the straw and transports it to the mixing chamber 200 for crushing, mixing, adding biological inoculants, and humidification, thereby achieving integrated harvesting, crushing, and fertilizer production. After fertilizer production is completed, the discharge gate 105 is opened to discharge the fertilizer for bagging.

[0043] During straw harvesting, the roots of the straw often carry soil. To reduce the amount of soil carried, specific structures can be designed as follows: Figure 1 In the embodiment shown, a filter grid plate 104 is detachably connected to the inner wall of the harvesting bucket 103 near the outside. In this embodiment, the filter grid plate 104 allows the straw to pass through the grooves between the filter grid plates 104 during the straw harvesting process, thereby peeling off larger pieces of soil and preventing larger pieces of soil from entering the mixing chamber 200 and affecting the fertilizer production effect.

[0044] Even after harvesting, the straw remains in a relatively long shape. To facilitate subsequent mixing and transportation, the straw needs to be cut. To achieve this cutting, a suitable structure can be used, such as... Figure 5 as well as Figure 6 In the embodiment shown, the adjustable support arm 102 is provided with a conveying channel inside. The bottom inner side of the conveying channel is detachably connected to a conveying component 106, which conveys the straw. The new energy unmanned walking vehicle frame 100 is detachably connected to the inner wall near the conveying component 106. In this embodiment, the reciprocating shearing of the reciprocating shearing machine 107 can cut the long straw into small segments, making it easier to convey, mix and make fertilizer.

[0045] To achieve the functions of mixing straw, adding biological inoculants, humidifying, and conveying straw into the mixing chamber 200, the specific structure can be as follows: Figure 5 In the embodiment shown, a mounting cover 204 is detachably connected to the upper end of the mixing chamber 200. A mixing component 201 is mounted on the mounting cover 204, which mixes the crushed straw. A humidifying component 203 is mounted on the mounting cover 204, which sprays water to humidify the straw, ensuring that the straw's moisture content meets the standard. A microbial inoculation component 202 is mounted on the mounting cover 204, which inoculates the straw with biological inoculants. The mixing chamber 200 and the conveying component 106... A primary crushing component 300 is provided in the mixing chamber 200. The primary crushing component 300 tilts and conveys the chopped straw into the mixing chamber 200, and crushes the straw a second time during the conveying process. In this embodiment, the mixing component 201 stirs the straw, so that the biological inoculum and the straw are fully mixed, and the straw moisture inside the mixing chamber 200 is also uniform. The primary crushing component 300 can crush the straw a second time during the conveying process, so that the straw entering the mixing chamber 200 is shorter.

[0046] The specific structure of the stirring assembly 201 can be as follows: Figure 7 In the embodiment shown, the mixing assembly 201 includes a mixing rod 205, a mixing and crushing blade 206, and a first servo motor 207. The first servo motor 207 is detachably connected to the upper end of the mounting cover plate 204. The rotating end of the first servo motor 207 extends through the mounting cover plate 204 and is detachably connected to the end of the mixing rod 205. The mixing and crushing blade 206 is fixedly connected to the outer wall of the mixing rod 205. There are multiple mixing and crushing blades 206. In this embodiment, the first servo motor 207 rotates to drive the mixing rod 205 and the mixing and crushing blade 206 to rotate, thereby enabling the mixing and crushing of straw.

[0047] The specific structure of the bacteria addition component 202 can be as follows: Figure 7 In the embodiment shown, the inoculum addition component 202 includes a biological inoculum chamber 208 and an inoculum addition ring 209. The biological inoculum chamber 208 is detachably connected to the upper end of the mounting cover plate 204, and the inoculum addition ring 209 is detachably connected to the bottom of the mounting cover plate 204. The inoculum addition device has a built-in power component. The power component transports the biological inoculum inside the biological inoculum chamber 208 to the inside of the mixing chamber 200 through the inoculum addition ring 209 to mix with the straw. In this embodiment, the power component can be a micro pump or a screw conveyor, depending on the morphology of the inoculum. The setting of the inoculum addition ring 209 allows the biological inoculum to fall in a ring shape, thereby increasing the sowing area of ​​the biological inoculum and making the mixing effect of the biological inoculum and straw better.

[0048] The specific structure of the humidification component 203 can be as follows: Figure 7 In the illustrated embodiment, the humidification component 203 includes a water storage tank 210 and a spray head 211. The water storage tank 210 is detachably connected to the upper end of the mounting cover 204, and the spray head 211 is detachably connected to the lower end of the mounting cover 204. The spray head 211 has a built-in water pump. The inlet end of the water pump is connected to the interior of the water storage tank 210, and the outlet end of the water pump is connected to the spray head 211. The spray head 211 is located on the side near where the straw enters the mixing chamber 200. In this embodiment, the water inside the water storage tank 210 is sprayed downwards through the spray head 211 by the water pump. Since the spray head 211 is located on the side near where the straw enters the mixing chamber 200, the sprayed water comes into contact with the straw entering the mixing chamber 200. When the straw enters the mixing chamber 200, its volume is small, which makes the water spray even, that is, the humidity of the straw is more uniform.

[0049] The specific structure of the primary crushing component 300 can be as follows: Figure 8 In the embodiment shown, the primary crushing assembly 300 includes a conveying track 301, a conveying auger 303, crushing teeth 302, and a second servo motor 305. The conveying auger 303 is rotatably connected to the inside of the conveying track 301. Multiple crushing teeth 302 are provided on the outer wall of each blade of the conveying auger 303. The second servo motor 305 is detachably connected to the outside of the new energy unmanned vehicle frame 100. The rotating end of the second servo motor 305 is inserted into the inside of the new energy unmanned vehicle frame 100 and detachably connected to one end of the conveying auger 303. Guides are provided on both sides of the upper end of the conveying track 301. The inclined surface 306 and the outer wall of each blade of the conveying auger rod 303 are provided with raised ridges. In this embodiment, the inclined surface 306 allows the cut straw to better contact the conveying auger rod 303. The second servo motor 305 drives the conveying auger rod 303 to rotate, thereby conveying the straw into the mixing chamber 200. The crushing teeth 302 apply shear force to the straw as they rotate during the conveying process, and the ridges generate a kneading force on the straw during the conveying process, further crushing the straw and improving the crushing effect.

[0050] During the straw crushing process, some fine soil particles are still carried along with the straw. This soil is also crushed into powder. To facilitate the removal of the crushed soil, a suitable structure can be adopted, such as... Figure 9 In the embodiment shown, a filter screen plate 304 is provided at the bottom of the conveying track 301. The interior of the new energy unmanned walking vehicle frame 100 below the filter screen plate 304 is connected to the outside. In this embodiment, the filter screen plate 304 allows the crushed soil to be discharged downward through the filter screen plate 304, thereby reducing the soil residue on the straw inside the mixing chamber 200 and making the fertilizer production effect better.

[0051] As soil powder falls through the filter screen 304, to prevent soil from clogging the holes in the filter screen 304, the conveying track 301 can vibrate to discharge the soil downwards. A specific structure can be adopted as follows: Figure 10 In the embodiment shown, a fan-shaped rotating plate 310 is detachably connected to the rotating end of the second servo motor 305. A U-shaped bracket 311 is detachably connected to the bottom inner side of the new energy unmanned vehicle frame 100 located on the conveying track 301. A striking rod 307 is rotatably connected inside the U-shaped bracket 311. A rubber striking head 308 is fixedly connected to one end of the striking rod 307 near the conveying track 301, and a rotating shaft 309 is rotatably connected to the other end of the striking rod 307 away from the conveying track 301. In this embodiment, the rotation of the conveying auger rod 303 drives the fan-shaped rotating plate 310 to rotate. The fan-shaped rotating plate 310 rotates... During operation, the rotating shaft 309 contacts the rubber striking head 308, causing it to tilt upwards and strike the conveying track 301. This causes the conveying track 301 to vibrate, assisting in soil discharge. After the fan-shaped rotating plate 310 rotates away, the striking rod 307 returns to its original position, allowing the conveying track 301 to vibrate continuously. The rotating shaft 309 reduces friction with the fan-shaped rotating plate 310, extending the device's lifespan. The rubber striking head 308 prevents damage to the outer wall of the conveying track 301 or the striking rod 307 caused by prolonged striking, further increasing the device's lifespan.

[0052] During the conveying process of the auger 303, the crushed soil tends to fly upwards, and the flying soil will still fall back onto the straw. To avoid this problem, the specific structure can be designed as follows: Figure 5 In the embodiment shown, a blowing assembly 400 is provided inside the new energy unmanned vehicle frame 100 above the conveying track 301. The blowing assembly 400 includes a blowing trough plate 401, an air inlet pipe 402, and a blower 403. The blowing trough plate 401 is located above the conveying track 301. The air inlet pipe 402 is connected to the blowing trough plate 401, and its other end extends out of the new energy unmanned vehicle frame 100 and is detachably connected to the air inlet end of the blower 403. The blower 403 is detachably connected to the outside of the new energy unmanned vehicle frame 100. In this embodiment, the blower 403 delivers pressurized air through the air inlet pipe 402 to the inside of the blowing trough plate 401. The air outlet of the blowing trough plate 401 blows towards the conveying track 301, causing the soil to be discharged through the opening at the bottom of the conveying track 301 that connects to the outside during the flying process. It can also assist the soil to fall downwards, thereby further reducing the soil residue of straw inside the mixing chamber 200.
