Description

Technical Field

[0001] The present invention relates to the technical field of straw combine harvesters, and particularly to a straw combine harvester with a hoisting type mesh bag. Background Art

[0002] In agricultural production, the harvesting of straw is an important link. At present, the combined harvesting of straw mainly relies on straw balers, straw shredders for returning to the field, or combine harvesters with forage collection functions. These devices have their own characteristics in terms of operation mode, collection efficiency, and subsequent processing. There are mainly two ways to process the harvested forage by traditional straw combine harvesters. One is to directly crush and scatter the forage back into the field. Although direct crushing and returning to the field eliminates the collection step, it is not conducive to the subsequent utilization of the forage, such as silage processing. The other is to process the silage after crushing and collecting.

[0003] The addition of silage agents is often carried out when the crushed forage accumulates in the container. However, this operation is greatly affected by the external environment. It is easy to cause the uneven mixing of the atomized silage agent and the forage due to the influence of air flow, and then lead to unstable preservation quality of the forage, resulting in mildew or nutrient loss. On the other hand, during the process of crushing and bagging the forage, the forage accumulates and stores in the container. The relative position between the ejection position of the forage and the container is fixed, which will cause the forage to accumulate in a mountain shape in the container, unable to achieve uniform distribution of the forage, affecting the storage capacity of the container for the forage, resulting in more frequent transfer of the accumulated forage, and affecting the working efficiency of the entire combine harvester. Therefore, the present application provides a straw combine harvester with a hoisting type mesh bag to meet the requirements. Summary of the Invention

The input shaft of the speed reducer is fixedly connected to the driving shaft of the servo motor, and a sector gear is sleeved on the output shaft of the speed reducer.

[0009] Optionally, a support frame is fixedly connected to the top of the forage output cabin. A support disc is sleeved on the outside of the forage output pipe and is located above the support frame. Ball bearings corresponding to the top end of the support frame and evenly distributed are sleeved on the support disc. The bottom end of the forage output pipe is located in the forage output cabin, and a limiting disc is sleeved on the outside of the bottom end of the forage output pipe.

[0010] Optionally, the teeth on the outside of the sector gear are distributed in a fan shape. The teeth on the transmission gear are adapted to the teeth on the sector gear.

[0011] Optionally, a transmission rod is sleeved on the mounting base, a stirring shaft corresponding to the position of the transmission rod is sleeved in the silage storage barrel, uniformly distributed stirring blades are fixedly connected to the outside of the stirring shaft, one end of the stirring shaft close to the transmission rod extends to the outside of the silage storage barrel and is fixedly connected with a connecting seat, and a connecting head is fixedly connected to one end of the transmission rod close to the connecting seat.

[0013] Optionally, symmetrically distributed guide plates are fixedly connected to the inner side wall of the mounting base, and pull rods are symmetrically mounted on the mounting base. The end of the pull rod extends into the mounting base and is fixedly connected with a fixing block.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the adding assembly and the straw output pipe, the crushed straw is output by relying on the pipeline structure formed by the straw output pipe, and the atomized mixing of the silage is synchronously carried out in the straw output pipe, isolating the influence of the external air flow, ensuring that the output straw can fully contact and mix with the silage, and thus ensuring the addition effect of the silage of the whole device.

[0016] By setting the straw output pipe and the deflection assembly, during the process of spraying straw by the straw output pipe, the straw output pipe can perform reciprocating deflection activities under the action of the deflection assembly, so that the straw sprayed by the straw output pipe can be evenly laid in the hoisting net bag, increasing the amount of straw that the hoisting net bag can store, reducing the hoisting and transfer frequency of the hoisting net bag, and then improving the working efficiency of the whole device.

[0017] By setting the deflection component and the stirring shaft and stirring blades in the silage storage barrel, while the deflection component is working, the stirring shaft and stirring blades in the silage storage barrel can be driven by a servo motor to rotate and stir, continuously stirring the silage stored in the silage storage barrel, avoiding the deposition of silage, thereby further ensuring the mixing effect between the silage and the forage, and improving the technical solution of the entire device.

[0018] By setting the deflection component and the positioning component, on the one hand, the positioning component is relied on to limit the active range of the forage output pipe, avoiding the forage output pipe from spraying forage to positions outside the hoisting net bag. On the other hand, it can cause the forage output pipe to collide and vibrate with the positioning plate, shaking off the forage adhered to the inner wall of the forage output pipe, ensuring the discharge effect of the forage, avoiding waste of forage and silage, and enabling the structures of the deflection component and the positioning component to cooperate to produce additional technical effects.

[0028] As Figures 1 to 12As shown, an embodiment of the present invention provides a straw and grain combined harvesting device with a hoisting net bag, including a straw and grain combine harvester 1. A straw processing chamber 2 is provided in the straw and grain combine harvester 1. The straw and grain combine harvester 1 and the straw processing chamber 2 cooperate to complete threshing, cleaning, and collection of grains such as wheat, rice, and barley, which is consistent with the functions of traditional combine harvesters. When harvesting grains, the straw is cut and crushed synchronously to avoid secondary operations and improve efficiency. The above-mentioned straw and grain combine harvester 1 and straw processing chamber 2 are both prior arts, and their working principles and working methods are the same as those of the prior art, so they will not be elaborated here. Fences 9 are symmetrically installed on both sides of the straw processing chamber 2. A hoisting net bag 8 is provided in the fences 9. The setting of the fences 9 can play a role in supporting and shaping the hoisting net bag 8, enabling the hoisting net bag 8 to form a container for storing forage and grain. A lifting ring is provided at the top of the hoisting net bag 8, and an opening is provided at the bottom. The opening is tied and sealed with a rope. After the grain or forage in the hoisting net bag 8 is full, the hoisting net bag 8 can be lifted by hoisting equipment, and the rope at the bottom of the hoisting net bag 8 is untied to pour out the grain and forage for the transfer of grain and forage. A grain output chamber 3 and a forage output chamber 25 are provided in the straw processing chamber 2. And a mounting seat 4 is fixedly connected to the top end of the straw processing chamber 2. A silage storage barrel 5 is assembled in the mounting seat 4. A forage output pipe 6 is sleeved on the top end of the forage output chamber 25. The processed grain and forage in the straw processing chamber 2 are separated. The separated grain is sprayed and stored in the hoisting net bag 8 through the grain output chamber 3. The forage is pulverized, and the pulverized forage is sprayed and stored in the hoisting net bag 8 on the other side through the forage output chamber 25 and the forage output pipe 6. The output end of the grain output chamber 3 corresponds to the position of the hoisting net bag 8 and the fence 9 on one side of the straw processing chamber 2. The end of the forage output pipe 6 extends above the hoisting net bag 8 and the fence 9 on the other side of the straw processing chamber 2. The end of the forage output pipe 6 is inclined downward. The downward inclination of the end of the forage output pipe 6 can ensure the position of the forage output through the forage output pipe 6, ensuring that the forage sprayed by the forage output pipe 6 can be stacked and stored in the hoisting net bag 8.

[0029] An adding component is used to mix the silage in the silage storage barrel 5 with the forage grass output from the forage grass output pipe 6. The adding component is connected to the mounting seat 4. The setting of the adding component enables the crushed forage grass to be discharged after the addition of the silage in the forage grass output pipe 6. The pipeline formed by the forage grass output pipe 6 can avoid the influence of external air flow and ensure that the crushed forage grass is in uniform and sufficient contact with the silage, thus ensuring the addition effect of the silage; A deflecting component is used to drive the relative deflecting movement between the forage grass output pipe 6 and the forage grass output cabin 25. The deflecting component is respectively connected between the cereal straw treatment cabin 2 and the forage grass output pipe 6. The setting of the deflecting component can drive the forage grass output pipe 6 to deflect repeatedly during the process of the forage grass being sprayed and stored in the hoisting net bag 8 through the forage grass output pipe 6, so that the forage grass sprayed from the forage grass output pipe 6 can be stored more uniformly in the hoisting net bag 8, increasing the amount of forage grass that the hoisting net bag 8 can store, avoiding frequent hoisting of forage grass, and ensuring the overall working efficiency of the device; A positioning component is used to limit and fix the forage grass output pipe 6 in real time. The positioning component is connected to the cereal straw treatment cabin 2. The setting of the positioning component can, on the one hand, limit the movement range of the forage grass output pipe 6 to prevent the forage grass from being sprayed outside the hoisting net bag 8 during the deflection of the forage grass output pipe 6, and on the other hand, make the forage grass output pipe 6 vibrate when contacting with the forage grass output pipe 6, shaking off the forage grass adhering to the wall of the forage grass output pipe 6 and reducing the waste of forage grass.

[0030] In this embodiment, as Figures 2 to 8 shown, the adding component includes a water pump 10 fixedly connected to the mounting seat 4. The input end of the water pump 10 is connected to the bottom of the silage storage barrel 5 through a pipeline, and the output end of the water pump 10 is fixedly connected with an atomizing nozzle 11 through a pipeline. The atomizing nozzle 11 is sleeved at the bent part of the forage grass output pipe 6. The silage storage barrel 5 stores silage. During the process of the forage grass output pipe 6 working and spraying the crushed forage grass into the hoisting net bag 8 for storage, the water pump 10 on the mounting seat 4 works synchronously, and the silage stored in the silage storage barrel 5 is pumped out through the pipeline. After being pumped out by the water pump 10, the silage is transported to the atomizing nozzle 11 through the pipeline. After being atomized by the atomizing nozzle 11, the silage is sprayed inside the forage grass output pipe 6, thus acting on the forage grass passing through the forage grass output pipe 6. Relying on the pipeline space formed by the forage grass output pipe 6, the interference of external air flow is avoided, ensuring that the passing forage grass can be in uniform contact with the atomized silage, and then ensuring the addition effect of the silage.

[0031] In this embodiment, as Figures 8 to 11As shown in the figure, the deflection assembly includes a servo motor 24 fixedly connected to the top of the straw processing chamber 2 and a transmission gear 32 fixedly connected to the outside of the straw output pipe 6. A speed reducer 30 is fixedly connected to the outside of the straw output chamber 25. The input shaft of the speed reducer 30 is fixedly connected to the drive shaft of the servo motor 24. A sector gear 31 is sleeved on the output shaft of the speed reducer 30. The teeth on the outside of the sector gear 31 are distributed in a sector shape. The teeth on the transmission gear 32 are adapted to the teeth on the sector gear 31. The part of the sector gear 31 without teeth is separated from the transmission gear 32. A torsion spring 34 is fixedly connected between the transmission gear 32 and the top of the straw output chamber 25. When the servo motor 24 works, it can drive the input shaft of the speed reducer 30 to rotate through its drive shaft. After being decelerated by the speed reducer 30, the output shaft of the speed reducer 30 drives the sector gear 31 to rotate. Then, the teeth of the sector gear 31 and the transmission gear 32 are engaged to drive the transmission gear 32 to rotate. When the transmission gear 32 rotates, it also drives the relative deflection between the straw output pipe 6 and the top of the straw output chamber 25. During the deflection of the transmission gear 32 and the straw output pipe 6, the torsion spring 34 is twisted, and the torsion spring 34 twists and accumulates elastic potential energy. After the toothed part of the sector gear 31 is separated from the transmission gear 32, the area of the sector gear 31 without teeth does not contact the transmission gear 32, and the meshing state between the sector gear 31 and the transmission gear 32 is released. After the transmission gear 32 loses the limit of the sector gear 31, it quickly resets under the action of the elastic force of the torsion spring 34. The sector gear 31, the transmission gear 32 and the torsion spring 34 cooperate to form the repeated deflection activity of the whole straw output pipe 6, so that the materials sprayed from the straw output pipe 6 can be evenly laid into the hoisting net bag 8. Without changing the capacity of the hoisting net bag 8, it is avoided that the straw sprayed from the straw output pipe 6 accumulates in a hillside shape, thereby increasing the amount of straw that the hoisting net bag 8 can store. Indirectly, the hoisting and transfer frequency of the straw in the hoisting net bag 8 is reduced, and the working efficiency of the whole device is ensured.

[0032] A support frame 26 is fixedly connected to the top of the forage output bin 25. A support disc 27 is sleeved outside the forage output pipe 6 and is located above the support frame 26. A plurality of balls 28 are sleeved on the support disc 27 and are evenly distributed corresponding to the top end position of the support frame 26. The bottom end of the forage output pipe 6 is located in the forage output bin 25, and a limit disc 33 is sleeved outside the bottom end of the forage output pipe 6. The bottom end of the forage output pipe 6 is movably connected to the top end of the forage output bin 25, so as to ensure that the forage output pipe 6 can deflect under the action of the deflection assembly. The support frame 26, the support disc 27 and the balls 28 are provided to limit the part of the forage output pipe 6 outside the forage output bin 25, and the limit disc 33 is provided to limit the part of the forage output pipe 6 inside the forage output bin 25. The cross section of the support frame 26 is T-shaped and surrounds the outside of the limit disc 33 and the torsion spring 34 to protect the limit disc 33 and the torsion spring 34. An opening is formed in the area of the support frame 26 facing the sector gear 31 to avoid hindering the meshing transmission between the teeth of the sector gear 31 and the transmission gear 32. The top end of the support frame 26 is in contact with the bottom ends of the balls 28 on the support disc 27 to provide support for the support disc 27 and the balls 28. During the relative deflection between the forage output pipe 6 and the forage output bin 25, the forage output pipe 6 will also drive the support disc 27 to rotate synchronously, and the balls 28 will roll. By relying on the rolling friction of the balls 28, it is avoided that the support disc 27 directly contacts the support frame 26 to generate a large sliding friction, so that the support frame 26, the support disc 27 and the balls 28 can cooperate to provide support for the forage output pipe 6, reduce the limit burden of the limit disc 33, and the wear during the deflection movement of the forage output pipe 6 is small, and the service life of the structure is long.

[0033] In this embodiment, as Figures 3 to 9As shown, a transmission rod 14 is sleeved on the mounting base 4, and a stirring shaft 20 corresponding to the position of the transmission rod 14 is sleeved in the silage storage barrel 5. Uniformly distributed stirring blades 21 are fixedly connected to the outside of the stirring shaft 20. One end of the stirring shaft 20 close to the transmission rod 14 extends to the outside of the silage storage barrel 5 and is fixedly connected with a connecting seat 22. One end of the transmission rod 14 close to the connecting seat 22 is fixedly connected with a connecting head 15. A connecting groove 23 adapted to the shape of the connecting head 15 is formed on the connecting seat 22. Synchronous wheels 16 are sleeved on the driving shaft of the servo motor 24 and the end of the transmission rod 14 far from the connecting head 15. The synchronous wheels 16 are connected by a synchronous belt 29. After the silage storage barrel 5 is assembled in the mounting base 4, the connecting head 15 on the transmission rod 14 can be embedded into the connecting groove 23 on the connecting seat 22, so that the transmission rod 14 and the stirring shaft 20 are connected through the connecting seat 22 and the connecting head 15. When the servo motor 24 works and drives the forage output pipe 6 to perform reciprocating deflection movements, it also drives the transmission rod 14 to rotate through the transmission of the synchronous wheels 16 and the synchronous belt 29, and then drives the stirring shaft 20 and the stirring blades 21 to stir the stored silage in the silage storage barrel 5, thereby preventing the silage from depositing during the operation of the device, ensuring the uniform composition of the silage, and indirectly ensuring the mixing effect of the silage and the forage.

[0034] Symmetrically distributed guide plates 13 are fixedly connected to the inner side wall of the mounting base 4, and pull rods 12 are symmetrically installed on the mounting base 4. The ends of the pull rods 12 extend into the mounting base 4 and are fixedly connected with fixing blocks 18. A spring 17 is fixedly connected between the fixing blocks 18 and the inner side wall of the mounting base 4. A fixing seat 19 adapted to the shape of the spring 17 is fixedly connected to the outside of the silage storage barrel 5. During the process of assembling the silage storage barrel 5 into the mounting base 4, the guide plates 13 can guide the silage storage barrel 5, guiding the pushing direction of the silage storage barrel 5 into the mounting base 4, ensuring that the connecting head 15 can be docked with the connecting seat 22 after the silage storage barrel 5 is assembled. During the process of assembling the silage storage barrel 5 in the mounting base 4, pulling the pull rod 12 can drive the fixing block 18 to approach the inner side wall of the mounting base 4 and compress the spring 17, increasing the distance between the two fixing blocks 18 to provide enough space for the entry of the silage storage barrel 5. After the connecting head 15 and the connecting seat 22 are docked, releasing the pull rod 12, the spring 17 can drive the fixing block 18 to be embedded into the fixing seat 19 under the action of its own elastic force, forming a limit fixation for the silage storage barrel 5, completing the assembly and fixation of the silage storage barrel 5 in the mounting base 4, making the assembly operation between the silage storage barrel 5 and the mounting base 4 simple and convenient, and facilitating the maintenance and replacement of the silage storage barrel 5 after long-term use.

[0035] In this embodiment, as Figures 11 to 12As shown in the figure, the positioning component includes a positioning plate 7 fixedly connected to the top of the straw processing chamber 2 and located outside the straw output pipe 6. A positioning groove 37 adapted to the shape of the straw output pipe 6 is formed on the positioning plate 7. A weakening groove 35 is formed in the middle of the positioning plate 7. The positioning plate 7 is in a wavy structure at the weakening groove 35, and the thickness value at the weakening groove 35 is thinner and the strength is weaker. After the positioning plate 7 is impacted by an external force, it is more likely to deform at the weakening groove 35. A positioning piece 36 is fixedly connected to the outside of the positioning groove 37. The positioning piece 36 is arc-shaped and is distributed up and down outside the positioning groove 37. It is also adapted to the external shape of the straw output pipe 6 and can provide limit support for the straw output pipe 6 when the straw output pipe 6 is docked with the positioning plate 7. After the teeth between the sector gear 31 and the transmission gear 32 are separated, the transmission gear 32 will drive the straw output pipe 6 to quickly reset under the action of the elastic force of the torsion spring 34. During this process, the positioning plate 7 can form a limit on the straw output pipe 6 to prevent the deflection range of the straw output pipe 6 from being too large, resulting in the straw ejected from the straw output pipe 6 being sprayed into an area outside the hoisting net bag 8. At the same time, after a collision occurs between the straw output pipe 6 and the positioning plate 7, the positioning plate 7 will deform at the weakening groove 35 and quickly recover under its own elastic force. Thus, due to the repeated contact between the positioning plate 7 and the straw output pipe 6, the straw output pipe 6 can generate high-frequency vibrations after resetting, and the materials adhering to the inner wall of the straw output pipe 6 can be shaken off, preventing the straw from adhering to the inner side wall of the straw output pipe 6 and being unable to be discharged after being mixed with the silage agent, resulting in waste of straw and silage agent. When the whole device is not in a working state, the straw output pipe 6 fits in the positioning groove 37 on the positioning plate 7 under the action of the elastic force of the torsion spring 34, and the positioning piece 36 on the positioning plate 7 wraps around the outside of the straw output pipe 6 to form support and limit for the straw output pipe 6, further reducing the limit burden on the straw output pipe 6 by the support frame 26, the support disk 27, the ball 28 and the limit disk 33.

[0036] The present invention covers any substitutions, modifications, equivalent methods and solutions made within the essence and scope of the present invention.

However, those skilled in the art can fully understand the present invention without these detailed descriptions. In addition, well-known methods, processes, procedures, components and circuits are not described in detail to avoid unnecessary confusion to the essence of the present invention.

[0037] The above are only the preferred embodiments of the present invention.
