Description

Technical Field

[0001] The invention relates to the technical field of straw processing, and in particular to harvesting and processing equipment for automatically collecting and processing corn straw. Background Art

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds. More than half of the products of crop photosynthesis are present in straw. Straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, and is a multi-purpose renewable biological resource. Straw is also a roughage. It is characterized by a high crude fiber content and contains lignin. Although lignin cellulose cannot be used by pigs and chickens, it can be absorbed and used by ruminants such as cattle and sheep.

[0003] At present, corn harvesters use the method of collecting ears separately or collecting ears and crushing corn stalks and returning them to the field. Generally, corn stalks are used as fertilizer after being crushed, but corn stalks are divided into several parts, namely stalk husk, pulp, and leaves. The pulp and leaves can be used as land fertilizer after rotting, while the main component of the husk is fiber, which takes a long time to rot and cannot improve the soil. Crushing and returning corn stalks to the field can easily cause soil bulking and reduce the soil's water storage capacity. Therefore, the method of crushing corn stalks and returning them to the field does not fully utilize the corn stalks and has a certain negative impact on agricultural production.

[0004] Therefore, it is particularly important to design a harvesting and processing equipment that automatically collects and processes corn stalks to solve the above-mentioned defects. Summary of the invention

The movable gear 209 is meshed with the first transmission gear 208, and the multiple groups of second transmission gears 209 are connected by the first pulley group 210. When harvesting corn stalks, the left end of the guide shaft 201 is fixedly installed on the transmission pulley, and is connected to the transmission system inside the harvester body 1 through the transmission pulley. When the harvester body 1 moves, the guide shaft 201 is started to drive it to rotate. When the guide shaft 201 rotates, the transmission shaft 204 is driven to rotate through the sprocket group 205. The pull rod rotating shaft 206 is driven to rotate under the transmission of the driving gear 207 and the first transmission gear 208, and the multiple groups of pull rod rotating shafts 206 rotate together under the transmission of the first pulley group 210, and the corn stalks are introduced into the interior of the harvesting frame 2 through the multiple groups of guide cone heads 203.

[0038] Furthermore, a spiral cone head 211 is fixedly connected to the front end of the rod pulling shaft 206, and multiple groups of rod pulling plates 212 are fixedly connected to the outer side of the rod pulling shaft 206. When the rod pulling shaft 206 rotates, the spiral cone head 211 is used to assist in transporting the straw into the interior of the harvesting frame 2. The straw is pulled apart and introduced into the interior of the harvesting frame 2 under the action of the multiple groups of rod pulling plates 212. Subsequently, when the guide shaft 201 rotates, the spiral directions of the two groups of guide spiral leaves 202 on the outer side are opposite, and the conveying directions of the two groups of guide spiral leaves 202 are opposite, thereby guiding the corn straw into the interior of the conveying frame 4 to complete the harvesting of the corn straw.

[0039] Then, a conveyor belt 401 is installed inside the conveying rack 4, and the rear end of the conveying rack 4 is fixedly connected to the top of the processing cylinder 6 through the connecting cover 402. After the corn stalks enter the conveying rack 4, they are transported by the conveyor belt 401 and then introduced into the processing cylinder 6 through the connecting cover 402.

When the first motor 501 is started, the crushing and threshing roller 7 and the impurity removal fan 602 are driven to rotate under the transmission of the second pulley group 607 and the third pulley group 608. When the corn stalks enter the interior of the processing cylinder 6, the crushing and threshing roller 7 is used to crush the corn stalks, and then the crushed corn stalks fall through the first screen 8, and then are discharged to the top of the screen plate 9 through the discharge hopper 601. In this process, the impurity removal fan 602 can blow away the lighter impurities therein. When the crushing and threshing roller 7 rotates, the screening shaft 606 is driven to rotate through the fourth pulley group 609, and when the screening shaft 606 rotates, the screen plate 9 is shaken back and forth, thereby screening the crushed corn stalks, and the corn kernels therein are screened and fall onto the discharge plate 10, thereby completing the sorting between corn stalks and corn kernels.

[0041] Furthermore, the aperture inside the sieve plate 9 is smaller than the aperture inside the first sieve 8, and a discharge port 901 is provided at the left end of the sieve plate 9 and the discharge plate 10, so that the crushed corn stalks and corn kernels can fall through the first sieve 8, and the sieve plate 9 can screen out the corn kernels.

[0042] Furthermore, a guide hopper 1201 is fixedly connected to the top of the hood 12, and a discharge pipe 1202 is fixedly connected to the bottom of the hood 12. The crushed corn stalks are screened and introduced into the interior of the hood 12 through the guide hopper 1201, and the granulation mechanism 13 is used to further crush the corn stalks into particles and discharge them from the discharge pipe 1202.

[0043] Secondly, the granulation mechanism 13 includes a second motor 1301 fixedly installed on the top of the fixed frame 11, and a rotating frame 1302 is rotatably connected to the driving end of the second motor 1301. A plurality of extrusion wheels 1303 are rotatably connected to the interior of the rotating frame 1302. A second screen 1304 is fixedly installed inside the hood 12 and on the outside of the rotating frame 1302, and the plurality of extrusion wheels 1303 are all in contact with the inner side of the second screen 1304. A crushing blade 1305 is fixedly installed on the front of the rotating frame 1302. The second motor 1301 is started to drive the rotating frame 1302 to rotate, and the corn stalks are further crushed by the crushing blade 1305. Subsequently, the crushed corn stalks are made into particles through the second screen 1304 by the plurality of extrusion wheels 1303. By making the corn stalks into particles, not only can the influence of returning the corn stalks to the field on the soil fertility be avoided, but the granulated corn stalks can also be used as feed, and the dried corn stalk particles can also be used as fuel, thereby greatly improving the utilization efficiency of the corn stalks.

[0044] Finally, multiple groups of extruding wheels 1303 are evenly spaced on the inner side of the rotating frame 1302, and multiple groups of extruding teeth 1306 are fixedly connected to the outer sides of the multiple groups of extruding wheels 1303. The extruding teeth 1306 on the outer sides of the multiple groups of extruding wheels 1303 can crush the crushed corn stalks, and after compaction, they are made into particles through the mesh holes on the second screen 1304.

[0045] In this embodiment, the implementation scenario is specifically as follows: when harvesting corn stalks, the left end of the guide shaft 201 is fixedly installed on the transmission pulley, and is connected to the transmission system inside the harvester body 1 through the transmission pulley. When the harvester body 1 is moving, the guide shaft 201 is started to drive it to rotate. When the guide shaft 201 rotates, the transmission shaft 204 is driven to rotate through the sprocket set 205, and the pull rod rotating shaft 206 is driven to rotate under the transmission of the driving gear 207 and the first transmission gear 208, and the multiple groups of pull rod rotating shafts 206 are rotated together under the transmission of the first pulley set 210, and the corn stalks are passed between the multiple groups of guide cone heads 203. The corn stalks are introduced into the interior of the harvesting frame 2. When the rod pulling shaft 206 rotates, the spiral cone head 211 is used to assist the straw to be transported into the interior of the harvesting frame 2. The straw is pulled off and introduced into the interior of the harvesting frame 2 under the action of multiple groups of rod pulling plates 212. Then, the corn stalks are introduced into the conveying frame 4 through the guide spiral blades 202 on the outside of the guide shaft 201. Then, the corn stalks are introduced into the interior of the processing cylinder 6 through the conveying frame 4. The crushing and threshing rollers 7 and the impurity removal fan 602 are driven to rotate under the transmission of the second pulley group 607 and the third pulley group 608. When the corn stalks enter the interior of the processing cylinder 6, the crushing and threshing rollers 7 are used to crush the corn stalks. The corn stalks are screened and the corn kernels are screened and dropped onto the discharge plate 10, thereby completing the separation between the corn stalks and the corn kernels. After screening, the crushed corn stalks are introduced into the interior of the machine cover 12 through the guide hopper 1201, and the second motor 1301 is started to drive the rotating frame 1302 to rotate, and the crushed corn stalks are screened and dropped onto the discharge plate 10, thereby completing the separation between the corn stalks and the corn kernels. The crushing blades 1305 further crush the corn stalks, and then use multiple sets of squeezing wheels 1303 to pass the crushed corn stalks through the second screen 1304 to make pellets. The whole operation process is simple and convenient. Compared with the existing corn stalk harvesting and processing methods, the present invention is designed to automatically harvest and process corn stalks, and can also sort corn stalks and corn kernels. Finally, by making the corn stalks into pellets, it can not only avoid the impact of returning the corn stalks to the field on the fertility of the land, but also the pelletized corn stalks can be used as feed, and the dried corn stalk pellets can also be used as fuel, which greatly improves the utilization efficiency of corn stalks.
