Abstract
Description
Technical Field
[0001] This application belongs to the technical field of agricultural machinery, and specifically relates to a shredder and a harvester. Background Art
[0002] At present, there are generally two ways to deal with the crop straw after threshing in a combine harvester. One is to cut the straw into pieces by a shredder and return it to the field to fertilize the land. The other is to directly return the whole straw to the field and then collect it as a high-quality feed for the livestock industry, which has certain economic value and does not require the shredder to work.
[0003] However, if the existing shredder needs to meet the requirement of not shredding the straw, it needs to stop the machine first and then remove it as a whole, or manually flip the guide plate in the shredder to achieve the whole straw return to the field. Therefore, it will consume a lot of time and manpower, and the blades of the shredder are sharp, which poses a safety hazard. Summary of the Utility Model
[0004] The purpose of this application is to provide a shredder and a harvester, which can conveniently and quickly switch the operation mode of the shredder, save time and effort, and improve the operation safety.
[0005] To achieve the above purpose, this application provides a shredder on the one hand, which includes:
[0006] A housing, including two side plates arranged at intervals left and right. Between the tops, bottoms and rears of the two side plates, a rolling cutting inlet, a rolling cutting outlet and a rear opening are respectively formed correspondingly;
[0007] A rolling cutting mechanism, arranged between the rolling cutting inlet and the rolling cutting outlet; and
[0008] A guiding mechanism, including a guide plate and a flipping power mechanism. The guide plate is connected between the two side plates in a vertically flipable manner and is located at the rear opening. The guide plate is provided with a rolling cutting guiding surface facing the rolling cutting mechanism and a straight discharging guiding surface facing away from the rolling cutting mechanism. The flipping power mechanism can drive the guide plate to flip between a rolling cutting guiding position for opening the rolling cutting inlet and a straight discharging guiding position for closing the rolling cutting inlet.
[0009] In some embodiments, the flipping power mechanism includes a telescopic power device, and the two ends of the telescopic power device are respectively connected to the housing and the guide plate correspondingly.
[0010] In some embodiments, the bottom of the guide plate is provided with a turning shaft and a connecting member. The left and right ends of the turning shaft are respectively rotatably connected to the two side plates. The connecting member is fixed to the end of the turning shaft and is located outside the side plate. The telescopic power device is arranged outside the side plate and the two ends are respectively hinged to the connecting member and the side plate.
[0011] In some embodiments, a fixed sleeve extending left and right and located between the two side plates is provided at the bottom of the guide plate, and the turning shaft is fixedly arranged through the fixed sleeve.
[0012] In some embodiments, the turning power mechanism further includes a position sensor for detecting the position of the telescopic power device.
[0013] In some embodiments, the position sensor includes a limit switch provided on the side plate and capable of being triggered by the telescopic power device.
[0014] In some embodiments, the guide plate is formed as a bent plate convex outwardly away from the rotary cutting mechanism.
[0015] In some embodiments, the bent plate includes a turning connecting plate segment, a rearward extending connecting plate segment, and an opening and closing connecting plate segment that are bent and connected in sequence from bottom to top. The turning connecting plate segment is turnably connected between the bottoms of the two side plates, and the opening and closing connecting plate segment is arranged to be able to open and close the rotary cutting inlet.
[0016] In some embodiments, the shredder further includes a front baffle provided between the front portions of the two side plates; in the straight discharge guiding position, the guide plate abuts against the front baffle to close the rotary cutting inlet; in the rotary cutting guiding position, the guide plate is spaced from the front baffle to open the rotary cutting inlet.
[0017] The second aspect of the present application further provides a harvester, which includes the above-mentioned shredder.
[0018] Through the above technical solutions, the shredder of the present application can drive the guide plate to turn between the rotary cutting guiding position and the straight discharge guiding position through the turning power mechanism, so as to realize the switching between the shredding mode and the straight discharge mode. When the guide plate is in the rotary cutting guiding position, the guide plate opens the rotary cutting inlet. At this time, the straw discharged from the threshing cylinder can enter the rotary cutting inlet under the guidance of the rotary cutting guiding surface of the guide plate, so that the rotary cutting mechanism can shred the straw and return the shredded material to the field through the rotary cutting outlet. When the guide plate is in the straight discharge guiding position, the guide plate closes the rotary cutting inlet. At this time, the straw discharged from the threshing cylinder can be directly and completely returned to the field under the guidance of the straight discharge guiding surface of the guide plate. Since the mode switching of the shredder is driven by the turning power mechanism (for example, the turning power mechanism can be triggered by an operator pressing a button or the like in the cab of the harvester), there is no need to manually perform operations such as removing the shredder or manually turning the guide plate, which not only saves time and effort and improves efficiency, but also avoids the operator being cut by the rotary cutting mechanism, thereby improving the operation safety.

[0035] The following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present application, and are not intended to limit the present application.
[0036] Referring to Figure 1 and Figure 2 , a first exemplary embodiment of the present application provides a shredder, which includes:
[0037] A housing, including two side plates 1 arranged at intervals left and right. Between the tops, bottoms, and rears of the two side plates 1, a rotary cutting inlet, a rotary cutting outlet, and a rear opening are respectively formed correspondingly;
[0038] A rotary cutting mechanism 2, arranged between the rotary cutting inlet and the rotary cutting outlet; and
[0039] A guiding mechanism, including a guiding plate 3 and a flipping power mechanism. The guiding plate 3 is rotatably connected between the two side plates 1 and is located at the rear opening. The guiding plate 3 is provided with a rotary cutting guiding surface 31 facing the rotary cutting mechanism 2 and a straight discharge guiding surface 32 facing away from the rotary cutting mechanism 2. The flipping power mechanism can drive the guiding plate 3 to flip between a rotary cutting guiding position for opening the rotary cutting inlet and a straight discharge guiding position for closing the rotary cutting inlet.
[0040] With the above settings, the shredder of the present application can drive the guiding plate 3 to flip between the rotary cutting guiding position and the straight discharge guiding position through the flipping power mechanism, so as to realize the switching between the shredding mode and the straight discharge mode.
[0041] Referring to Figure 3 , when the guiding plate 3 is in the rotary cutting guiding position, the guiding plate 3 opens the rotary cutting inlet. At this time, the straw discharged from the threshing cylinder 10 can enter the rotary cutting inlet under the guidance of the rotary cutting guiding surface 31 of the guiding plate 3, so that the rotary cutting mechanism 2 can shred the straw and return the shredded material to the field through the rotary cutting outlet. Usually, the rotary cutting mechanism 2 is provided with a fixed knife assembly 21 and a moving knife assembly 22. The moving knife assembly 22 can rotate to pull the straw between the fixed knife assembly 21 and the moving knife assembly 22, so as to shred the straw by using the blades of the fixed knife assembly 21 and the moving knife assembly 22. Furthermore, the shredded straw can be discharged through the rotary cutting outlet. In addition, a spreader 9 can be connected at the rotary cutting outlet to spread the material evenly by using the spreader 9.
[0042] Referring to Figure 4 , when the guiding plate 3 is in the straight discharge guiding position, the guiding plate 3 closes the rotary cutting inlet. At this time, the straw discharged from the threshing cylinder 10 can be directly and completely returned to the field under the guidance of the straight discharge guiding surface 32 of the guiding plate 3.
[0043] It can be seen that since the mode switching of the shredder is driven by the flipping power mechanism (for example, it can be triggered by an operator pressing a button or the like in the cab of the harvester to operate the flipping power mechanism), there is no need to manually remove the shredder or manually flip the guide plate 3, etc. This not only saves time and effort and improves efficiency, but also avoids the operator being cut by the rotary cutting mechanism 2, thereby improving operation safety.
[0044] In some embodiments, the flipping power mechanism includes a telescopic power device 6 (such as a hydraulic cylinder, an electric cylinder, a linear motor, etc., and the present application does not limit this). The two ends of the telescopic power device 6 are respectively connected to the housing and the guide plate 3 correspondingly. Thus, when the telescopic power device 6 expands and contracts, it can drive the guide plate 3 to flip up and down, so that the shredder switches to the shredding mode or the direct discharge mode. For example, the operator can trigger the operation of the telescopic power device 6 by pressing a button or the like in the cab of the harvester, which is convenient and fast, and has high safety and stability.
[0045] In some embodiments, the bottom of the guide plate 3 is provided with a rotation shaft 4 and a connecting member 5. Among them, the left and right ends of the rotation shaft 4 are respectively rotatably connected to the two side plates 1. The connecting member 5 is fixed to the end of the rotation shaft 4 and is located outside the side plate 1. The telescopic power device 6 is arranged outside the side plate 1 and its two ends are respectively hinged to the connecting member 5 and the side plate 1. When the telescopic power device 6 expands and contracts, the telescopic power device 6 can drive the connecting member 5 to swing, thereby driving the rotation shaft 4 to rotate, so that the guide plate 3 is integrally flipped. In addition, both the telescopic power device 6 and the connecting member 5 are located outside the side plate 1 and do not occupy the internal space of the housing, so as not to affect the normal movement of the straw in the shredding mode of the shredder.
[0046] In some embodiments, the bottom of the guide plate 3 is provided with a fixed sleeve 33 that extends left and right and is located between the two side plates 1. At this time, the rotation shaft 4 can be passed through and fixed in the fixed sleeve 33 to ensure that the rotation of the rotation shaft 4 is synchronized with the overall flipping of the guide plate 3.
[0047] In some embodiments, the flipping power mechanism further includes a position sensor 7 for detecting the position of the telescopic power device 6. By detecting the position of the telescopic power device 6 with the position sensor 7, the real-time flipping angle of the guide plate 3 can be further determined through a preset position relationship, which is convenient for realizing functions such as limiting the flipping amplitude and adjusting the flipping angle of the guide plate 3. That is, the position sensor 7 provides a detection basis for realizing these functions.
[0048] In some embodiments, the position sensor 7 includes a limit switch provided on the side plate 1 and capable of being triggered by the telescopic power device 6. In other words, the maximum moving stroke of the telescopic power device 6 can be limited by the limit switch.
[0049] For example, it can be referred to Figure 1, the telescopic power device 6 can adopt a hydraulic cylinder. The cylinder barrel of the hydraulic cylinder is hinged to the side plate 1, and the telescopic rod of the hydraulic cylinder is hinged to the connecting member 5. When the telescopic rod extends, it can drive the guide plate 3 to close the rolling cutting inlet; when the telescopic rod retracts, it can drive the guide plate 3 to open the rolling cutting inlet. At this time, a limit switch can be set on the retraction path of the telescopic rod. When the telescopic rod retracts to trigger the limit switch, the limit switch can send a stop signal. Then, the controller in the harvester can control the telescopic power device 6 to stop running according to this stop signal, so that the guide plate 3 stops flipping, thus limiting the maximum opening amplitude of the rolling cutting inlet.
[0050] In some embodiments, the guide plate 3 is formed as a bent plate protruding away from the rolling cutting mechanism 2, so as to increase the space between the chopper and the threshing cylinder 10 in the chopping mode, enabling more straw to enter the chopper per unit time, thereby improving the chopping efficiency.
[0051] In some embodiments, referring to Figure 2 , the guide plate 3 formed as a bent plate may include a flipping connecting plate segment 34, a rearward extending connecting plate segment 35, and an opening and closing connecting plate segment 36 that are bent and connected in sequence from bottom to top. Among them, the flipping connecting plate segment 34 is flip-ably connected between the bottoms of the two side plates 1. The opening and closing connecting plate segment 36 can open and close the rolling cutting inlet through the overall flipping of the guide plate 3, and the rearward extending connecting plate segment 35 is mainly used to make the guide plate 3 protrude away from the rolling cutting mechanism 2 to increase the space between the chopper and the threshing cylinder 10 in the chopping mode.
[0052] This application does not limit whether the flipping connecting plate segment 34, the rearward extending connecting plate segment 35, and the opening and closing connecting plate segment 36 adopt detachable connections. In the case of adopting detachable connections, the guide plate 3 has the advantage of being convenient for disassembly and maintenance.
[0053] In some embodiments, the chopper further includes a front baffle 8 disposed between the fronts of the two side plates 1. Referring to Figure 4 , in the straight-through guiding position, the guide plate 3 abuts against the front baffle 8 to close the rolling cutting inlet; referring to Figure 3 , in the rolling cutting guiding position, the guide plate 3 is spaced from the front baffle 8 to open the rolling cutting inlet.
[0054] Referring to Figure 3 and Figure 4 , the second exemplary embodiment of this application also provides a harvester, which includes the above-mentioned chopper and generally further includes a threshing cylinder 10 whose tail is connected to the chopper. Obviously, this harvester has all the technical effects brought by the above-mentioned chopper, so it will not be elaborated here.
