Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, specifically relating to a header assembly and operating equipment for harvesting both ears and stalks. Background Technology

[0002] As a major food crop, corn's planting area is expanding daily, leading to the widespread application of corn harvesters. In existing technology, the header of a corn harvester is typically powered by an engine, which is then connected to the header's input shaft via multi-stage transmission. Power is then distributed to the auger, feed rollers, and cutters through the header's transmission box and various transmission methods such as chains and belts. When the header needs to be reversed, the operator must manipulate a mechanical handle to switch the gear engagement position within the header's transmission box and activate a separately designed reversing device to reverse the header and feed rollers.

[0003] However, the above method has obvious shortcomings: First, the header is located at the end of the transmission system, and is easily affected by the transmission links in front during operation, often resulting in problems such as power transmission attenuation and insufficient power; Second, during harvesting operations, if the feeding amount is too large or the field crop conditions are poor, the header and feeding part are very easy to get clogged. At this time, the gear state must be adjusted by the handle to clear the blockage, and manual reset is required afterwards, which is cumbersome and inefficient, thus affecting the continuity of the overall operation. Summary of the Invention

[0004] The purpose of this application is to provide a header assembly and operating equipment that can harvest both ears and stalks, in order to solve the problems of insufficient power of the header and cumbersome operation and low efficiency when the existing transmission method is blocked, which affects the continuity of the overall operation.

[0005] To achieve the above objectives, the first aspect of this application provides a spikelet and stem harvesting type header assembly, comprising: Lower cutting table device; The upper cutting platform device is pivotally mounted above the lower cutting platform device; A feeding device is disposed at the rear end of the lower cutting platform device, and the feeding device has a lower feeding mechanism that docks with the lower cutting platform device and an upper feeding mechanism that docks with the upper cutting platform device. A power take-off device used to output forward or reverse rotational motion; The transmission device has its input side connected to the power output device, and its output side is connected to the lower cutting table device, the upper cutting table device, the lower feeding mechanism, and the upper feeding mechanism, respectively.

[0006] As a further improvement to the above technical solution: In some embodiments, the power output device is a hydraulically driven rotary device or an electrically driven rotary device.

[0007] In some embodiments, the transmission device includes a gearbox, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, and a fourth transmission mechanism. The gearbox is disposed on the lower cutting table device and has an input end, a first output end, a second output end, a third output end, and a fourth output end. The input end is drivenly connected to the power output device. The first output end is drivenly connected to the upper cutting table device through the first transmission mechanism. The second output end is drivenly connected to the lower cutting table device through the second transmission mechanism. The third output end is drivenly connected to the upper feeding mechanism through the third transmission mechanism. The fourth output end is drivenly connected to the lower feeding mechanism through the fourth transmission mechanism.

[0008] In some embodiments, the gearbox is disposed on one side of the lower cutting table device and located at one end of the lower cutting table device near the feeding device.

[0009] In some embodiments, the gearbox has opposite outer and inner sides in the width direction of the lower cutting table device, the inner side of the gearbox faces the feeding device, and the power output device is arranged on the inner side of the gearbox. The input terminal, the third output terminal, and the fourth output terminal are located inside the gear transmission box, while the first output terminal and the second output terminal are located outside the gear transmission box.

[0010] In some embodiments, the upper cutting platform device has an upper cutting platform chain drive system that is connected to the first transmission mechanism, and the upper cutting platform chain drive system is located on the side of the upper cutting platform device closer to the gear transmission box; the lower cutting platform device has a lower cutting platform chain drive system that is connected to the second transmission mechanism, and the lower cutting platform chain drive system is located on the side of the lower cutting platform device closer to the gear transmission box.

[0011] In some embodiments, the upper cutting table chain drive system includes a main drive shaft assembly arranged close to the lower cutting table device, with both ends of the main drive shaft assembly extending along the width direction of the upper cutting table device. The first transmission mechanism is a chain drive mechanism, with the driving sprocket of the chain drive mechanism located at the first output end and the driven sprocket located at the end of the main drive shaft assembly near the gear transmission box.

[0012] In some embodiments, the main drive shaft assembly includes a main shaft section and at least one auxiliary shaft section coaxially arranged, the main shaft section and the auxiliary shaft section being connected by a transmission component.

[0013] In some embodiments, a first ear-picking output sprocket, a second ear-picking output sprocket, and a feeding output sprocket are sequentially spaced on the secondary shaft section. The first ear-picking output sprocket and the second ear-picking output sprocket are respectively connected to the ear-picking transmission box in the upper cutting platform device, and the feeding output sprocket is connected to the feeding roller in the lower cutting platform device.

[0014] To achieve the above objectives, a second aspect of this application provides an operating device including a stalk-harvesting header assembly according to the first aspect.

The power output of this device is directly distributed and transmitted to the lower header, upper header, lower feed mechanism, and upper feed mechanism via the output side of the transmission device. Compared to the long transmission path formed by traditional step-by-step transmission, this structure is more compact, has higher transmission efficiency, and is more stable. This high transmission efficiency and stability reduce the risk of feed blockage. Even if blockage occurs, the lower header, upper header, lower feed mechanism, and upper feed mechanism can be reversed by the reverse rotational motion output by the power output device to clear the blockage, eliminating the need for manual control and greatly improving operational convenience and work efficiency.

[0016] In addition, the independently configured power output device is not affected by the engine of the whole machine, so its speed can be adjusted independently to meet the needs of different working conditions.

[0020] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0022] Example On the one hand, this embodiment provides a header assembly that can harvest both ears and stalks, which can be used in operating equipment, especially corn harvesters.

[0023] Please see Figure 1 and Figure 2 The stalk-harvesting header assembly provided in this embodiment includes a lower header device 100, an upper header device 200, a feeding device 300, a power output device 500, and a transmission device 400. The lower header device 100 and the upper header device 200 are arranged vertically, with the upper header device 200 positioned above the lower header device 100 and pivotally connected to it via fixed pipe clamps 120 on both sides. The lower header device 100 is responsible for stalk harvesting, while the upper header device 200 is responsible for ear harvesting.

[0024] The feeding device 300 is located at the rear end of the lower cutting platform device 100 (at one end close to the vehicle body). The feeding device 300 has a lower feeding mechanism that docks with the lower cutting platform device 100 and an upper feeding mechanism that docks with the upper cutting platform device 200.

[0025] The power output device 500 is connected to the input side of the transmission device 400, and the power output device 500 is used to output forward or reverse rotational motion. The output side of the transmission device 400 is connected to the lower cutting table device 100, the upper cutting table device 200, the lower feeding mechanism, and the upper feeding mechanism, respectively.

[0026] It is understood that the ear-and-stem harvesting header assembly provided in this embodiment is powered by an independent power output device 500. The power output from the power output device 500 is directly distributed and transmitted to the lower header device 100, upper header device 200, lower feeding mechanism, and upper feeding mechanism via the output side of the transmission device 400. Compared to the long transmission route formed by traditional step-by-step transmission, this structure is more compact, has higher transmission efficiency, and is more stable. This high transmission efficiency and stability reduce the risk of feed blockage. Even if blockage occurs, the lower header device 100, upper header device 200, lower feeding mechanism, and upper feeding mechanism can be reversed to clear the blockage by the reverse rotational motion output by the power output device 500, eliminating the need for manual control and greatly improving operational convenience and efficiency. In other words, the forward rotational motion output by the power output device 500 is used for the normal operation of the ear-and-stem harvesting header assembly.

[0027] In addition, the independently configured power output device 500 is not affected by the engine of the whole machine, so its speed can be adjusted independently to meet the needs of different working conditions.

[0028] In this embodiment, the power output device 500 is either a hydraulically driven rotary device or an electrically driven rotary device. When the hydraulically driven rotary device is a hydraulic motor, an additional hydraulic control system can be configured for the hydraulic motor, or it can be directly connected to the vehicle's hydraulic system. This facilitates the vehicle control system in adjusting the speed and rotation direction of the hydraulic motor. When the electrically driven rotary device is an electric motor or an electric motor, a storage battery can be configured to provide electrical energy for driving the device, and the vehicle control system can adjust the speed and rotation direction of the electrically driven rotary device.

[0029] The transmission device 400 includes a gearbox 410, a first transmission mechanism 420, a second transmission mechanism 430, a third transmission mechanism 440, and a fourth transmission mechanism 450. The gearbox 410 is mounted on the lower cutting table device 100 and has an input end 411a, a first output end 412a, a second output end 413a, a third output end 414a, and a fourth output end 415a. The input end 411a of the gearbox 410 is connected to the power output device 500, for example, through a splined sleeve or a coupling. The first output terminal 412a, the second output terminal 413a, the third output terminal 414a, and the fourth output terminal 415a can each output corresponding torque. The first output terminal 412a is connected to the upper cutting table device 200 via a first transmission mechanism 420; the second output terminal 413a is connected to the lower cutting table device 100 via a second transmission mechanism 430; the third output terminal 414a is connected to the upper feeding mechanism via a third transmission mechanism 440; and the fourth output terminal 415a is connected to the lower feeding mechanism via a fourth transmission mechanism 450. Thus, the gear transmission box 410 can distribute the power input from the power output device 500 to the upper cutting table device 200, the lower cutting table device 100, the upper feeding mechanism, and the lower feeding mechanism respectively through their corresponding output terminals.

[0030] It is understood that the cutting table assembly provided in this embodiment transmits the power supplied by the gear transmission box 410 in the power input device to the corresponding devices through the first output end 412a, the second output end 413a, the third output end 414a and the fourth output end 415a, respectively, via the corresponding first transmission mechanism 420, the second transmission mechanism 430, the third transmission mechanism 440 and the fourth transmission mechanism 450. Among them, the first transmission mechanism 420 transmits power to the upward cutting table device 200, the second transmission mechanism 430 transmits power to the downward cutting table device 100, the third transmission mechanism 440 transmits power to the upward feeding mechanism, and the fourth transmission mechanism 450 transmits power to the downward feeding mechanism.

[0031] Thus, in the cutting platform assembly provided in this embodiment, the power input device integrates the transmission mechanism through the gear transmission box 410. Furthermore, the power of the lower feeding mechanism and the upper feeding mechanism of the lower cutting platform device 100, the upper cutting platform device 200, and the feeding device 300 are all directly distributed by the gear transmission box 410, avoiding the long transmission route formed by continuous step-by-step transmission. This results in a more compact structural layout and improves transmission efficiency and stability.

[0032] Furthermore, the gear transmission box 410 integrates the first transmission mechanism 420, the second transmission mechanism 430, the third transmission mechanism 440, and the fourth transmission mechanism 450, simplifying the transmission route and structure and making it easier for later maintenance and repair work.

[0033] Please see Figure 1 In this embodiment, the gear transmission box 410 is disposed on one side of the lower cutting table device 100 and located at the end of the lower cutting table device 100 near the feeding device 300. Thus, the side-mounted gear transmission box 410 provides a good operating view and a spacious operating area. This has the following advantages: on the one hand, it facilitates installation and debugging by operators, and on the other hand, it facilitates centralized maintenance and repair.

[0034] Please see Figure 1 , Figure 2 and Figure 3 Furthermore, the upper cutting platform device 200 has an upper cutting platform chain drive system 210 that is connected to the first transmission mechanism 420. The upper cutting platform chain drive system 210 is located on the side of the upper cutting platform device 200 near the gear transmission box 410; the lower cutting platform device 100 has a lower cutting platform chain drive system 110 that is connected to the second transmission mechanism 430, and the lower cutting platform chain drive system 110 is located on the side of the lower cutting platform device 100 near the gear transmission box 410. Thus, based on the aforementioned side-mounted arrangement of the gear transmission box 410, the main transmission chain structure of the entire cutting platform assembly can be concentrated on the side (e.g., Figure 1 and Figure 3 (The left side of the view shown) facilitates installation and subsequent maintenance and repair.

[0035] The upper cutting table chain drive system 210 includes a main drive shaft assembly 211, which is arranged near the lower cutting table device 100. Both ends of the main drive shaft assembly 211 extend along the width direction of the upper cutting table device 200. The first transmission mechanism 420 is a chain drive mechanism. The driving sprocket of the chain drive mechanism is located at the first output end 412a and is driven connected to the first output shaft 412 (described below) of the first output end 412a (e.g., via a key). The first output shaft 412 can drive the driving sprocket to rotate. The driven sprocket is located at one end of the main drive shaft assembly 211 near the gear transmission box 410. The driven sprocket is driven connected to the main drive shaft assembly 211 (e.g., via a key), and the driven sprocket can drive the main drive shaft assembly 211 to rotate.

[0036] For further details, please refer to the following: Figure 4 and Figure 5 The main drive shaft assembly 211 includes a main shaft section 2110 and at least one auxiliary shaft section 2111 coaxially arranged. The main shaft section 2110 and the auxiliary shaft section 2111 are connected by a transmission component 2112. The main shaft section 2110 is drive-connected to the first transmission mechanism 420. It is understood that by designing the main drive shaft assembly 211 as a combination of a main shaft section 2110 and at least one auxiliary shaft section 2111, the difficulty of machining long shafts can be reduced, machining accuracy can be guaranteed, and even if one section is damaged, only partial replacement is required, thereby greatly saving costs and improving maintenance convenience.

[0037] Specifically, this embodiment illustrates a main shaft section 2110 and a secondary shaft section 2111, wherein the transmission component 2112 enables a transmission connection between the main shaft section 2110 and the secondary shaft section 2111. Optionally, the transmission component 2112 may be a coupling, a flange connection structure, or a spline sleeve, etc. It should be understood that the above is only for illustrative purposes and is not intended to limit the scope of protection of this application.

[0038] The upper cutter head chain drive system 210 also includes a transition shaft assembly 212, a drive shaft assembly 213, and an upper auger input device 214. The transition shaft assembly 212 is located on the side of the upper cutter head device 200 away from the lower cutter head device 100 and is connected to the main drive shaft assembly 211 via a chain drive mechanism.

[0039] Please see Figure 4 and Figure 5Specifically, the transition shaft assembly 212 is located above the main shaft section 2110, and the transition shaft assembly 212 is rotatably mounted to the frame of the upper cutting table device 200 via a bearing with a mounting seat. The transition shaft assembly 212 is equipped with a transition input sprocket 2120, and the main shaft section 2110 is equipped with a main drive output sprocket 2113 corresponding to the transition input sprocket 2120. The main drive output sprocket 2113 and the transition input sprocket 2120 are connected by a closed-loop chain.

[0040] Please see Figure 4 and Figure 5 The drive shaft assembly 213 and the transition shaft assembly 212 are connected by a chain drive mechanism to transmit power to the conveyor belt of the upward cutting table device 200. Specifically, the transition shaft assembly 212 is provided with a transition output sprocket 2121, and the drive shaft assembly 213 is provided with a belt input sprocket 2130. The transition output sprocket 2121 and the belt input sprocket 2130 are driven by a closed-loop chain.

[0041] Please see Figure 4 and Figure 5 The upper auger input device 214 is connected to the drive shaft assembly 213 via a chain drive mechanism to transmit power to the upper auger of the upper cutting table device 200. Specifically, the upper auger input device 214 includes a parallel-arranged input short shaft 2140 and an auger main shaft 2141; the input short shaft 2140 is equipped with a coaxially arranged auger input sprocket 2142 and a transition gear 2143, and the auger input sprocket 2142 is connected to the drive shaft assembly 213 via a chain drive mechanism. The drive shaft assembly 213 is also equipped with a belt output sprocket 2131, which is connected to the auger input sprocket 2142 via a closed-loop chain. The auger main shaft 2141 is equipped with a reversing gear 2144 that meshes with the transition gear 2143, and the auger main shaft 2141 is used to transmit power to the upper auger.

[0042] Thus, in the upper auger input device 214, the auger input sprocket 2142 and the transition gear 2143 share the input short shaft 2140, and two pairs of gears mesh to achieve reversal, effectively improving the compactness of the structure. Moreover, gear meshing reversal is more efficient and reliable than traditional chain or belt drives.

[0043] Please see Figure 4 and Figure 6The secondary shaft section 2111 of the main drive shaft assembly 211 is used to transmit power to the ear-picking box in the upper header device 200 and to the feed roller 111 in the lower header device 100. The ear-picking box includes a right-middle ear-picking box and a right ear-picking transmission box. A first ear-picking output sprocket 2114, a second ear-picking output sprocket 2115, and a feed output sprocket 2116 are sequentially spaced on the secondary shaft section 2111. The first ear-picking output sprocket 2114 and the second ear-picking output sprocket 2115 are respectively connected to the outer sprockets of the right-middle ear-picking transmission box and the right ear-picking transmission box via chains.

[0044] Furthermore, there are two feed rollers 111, namely a front feed roller 111b and a rear feed roller 111a. The lower cutting table device 100 also has a reversing sprocket 130 between the feed rollers 111 and the secondary shaft section 2111, with a secondary sprocket on one side of the reversing sprocket 130. A feed output sprocket 2116 is provided on the secondary shaft section 2111, and the feed output sprocket 2116 is connected to the reversing sprocket 130 via a chain. Then, the secondary sprocket on one side of the reversing sprocket 130 is connected to the rear feed input sprocket on the rear feed roller 111a and the front feed input sprocket on the front feed roller 111b via a chain drive structure.

[0045] In some embodiments, the feed output sprocket 2116, the reversing sprocket 130 and the chain therebetween can be replaced with a gear set or gearbox, through which the secondary shaft segment 2111 is transmitted to the feed roller 111.

[0046] The secondary shaft section 2111 is equipped with a first ear-picking output sprocket 2114 and a second ear-picking output sprocket 2115, which are respectively connected to the outer sprockets of the right-middle ear-picking transmission box and the right-side ear-picking transmission box via chains. Simultaneously, the end of the secondary shaft section 2111 away from the main shaft section 2110 is also equipped with a feeding output sprocket 2116, which is connected to the right sprocket of the feeding roller 111 in the lower header device 100 via a chain, providing corresponding power input to the feeding roller 111. The feeding roller 111 is one of the components of the lower header device 100, and its meaning is similar to that of a straw-turning roller.

[0047] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the lower cutting table chain drive system 110 includes a swing ring box 112 and a lower auger input device 113, which are spaced apart along the length of the lower cutting table device 100. The lower auger input device 113 is located between the swing ring box 112 and the gear transmission box 410. The swing ring box 112 and the lower auger input device 113 are respectively connected to the second output end 413a through a second transmission mechanism 430.

[0048] Specifically, the second transmission mechanism 430 between the swing ring box 112 and the second output end 413a can be connected by a belt drive mechanism. The second transmission mechanism 430 between the lower auger input device 113 and the second output end 413a can be connected by a chain drive mechanism. Thus, a sprocket and a pulley can be coaxially arranged on the second output shaft 413 (described below) forming the second output end 413a, with the pulley located on the side facing outward from the sprocket. In some embodiments, the second transmission mechanism 430 connecting the swing ring box 112 and the lower auger input device 113 to the second output end 413a can both be selected as chain drive mechanisms.

[0049] The aforementioned gear transmission box 410 is located in the width direction of the lower cutting table device 100 (e.g., Figure 1 or Figure 2 The gearbox 410 has an inner and outer side (indicated by arrow W in the width direction). The input end 411a, the third output end 414a and the fourth output end 415a are distributed on the inner side of the gearbox 410, while the first output end 412a and the second output end 413a are distributed on the outer side of the gearbox 410.

[0050] Please refer to the following: Figure 7 The gearbox 410 includes a housing 410a and an input shaft 411, a first output shaft 412, a second output shaft 413, a third output shaft 414, and a fourth output shaft 415 arranged parallel to each other within the housing 410a. The ends of the input shaft 411, the first output shaft 412, the second output shaft 413, the third output shaft 414, and the fourth output shaft 415 respectively form an input end 411a, a first output end 412a, a second output end 413a, a third output end 414a, and a fourth output end 415a.

[0051] In this embodiment, the input shaft 411 and the first output shaft 412 are connected by a first reduction gear set 416; the first output shaft 412 and the second output shaft 413 are connected by a second reduction gear set 417; the first output shaft 412 and the third output shaft 414 are connected by a third reduction gear set 418; and the second output shaft 413 and the fourth output shaft 415 are connected by a fourth reduction gear set 419. The gears and shafts can be connected using splines or flat keys, or the gears and shafts can be machined together to form a gear shaft.

[0052] Furthermore, the third transmission mechanism 440 is selected as an upper universal joint drive shaft, wherein the third output shaft 414 forming the third output end 414a is connected to the upper feeding mechanism via the upper universal joint drive shaft; the fourth transmission mechanism 450 is selected as a lower universal joint drive shaft, wherein the fourth output shaft 415 forming the fourth output end 415a is connected to the lower feeding mechanism via the lower universal joint drive shaft. This solves the problem in the prior art where the feeding device 300 is located at the end of the transmission of the entire cutting table assembly, making it highly susceptible to interference from other components during operation and prone to insufficient power, thereby significantly improving transmission efficiency and reliability.

[0053] It should be noted that the transmission connection achieved through the chain drive mechanism described above can also be replaced by a synchronous belt mechanism, with the specific layout being the same as the chain drive mechanism, and will not be repeated in this embodiment. Considering the ease of installation, transmission efficiency, transmission reliability, and maintainability, this embodiment preferably uses a chain drive mechanism.

[0054] On the other hand, this embodiment also provides a working device, including a header assembly for harvesting both ears and stalks according to the above embodiment. The working device can be a corn harvester with ear and stalk harvesting capabilities.

[0055] It is understood that the working equipment provided in this embodiment adopts the cutting table assembly provided in the above embodiment, and therefore has all the beneficial effects of the cutting table assembly. To avoid repetition, it will not be described in detail here.

[0056] It should be noted that, in this application, unless otherwise stated, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
