Description

Technical Field

[0001] This invention belongs to the field of harvester technology, and particularly relates to a grain-reeling component, a grain-reeling assembly, and a millet harvester. Background Technology

[0002] Millet (also known as foxtail millet) belongs to the genus *Sorghum* of the Poaceae family. It is a top-earing crop, and its stalks are similar to those of sorghum, being relatively thick and tall. Currently, millet is mainly harvested using harvesters modified from wheat and other crops. By integrating the processes of harvesting, baling, and bagging, the harvesting effect of millet harvesters is not good due to the characteristics of its ears and stalks being relatively thick. In particular, there are problems such as stalk jamming and high grain loss. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, one of the objectives of the present invention is to provide a simple structure that has a good effect on conveying millet straw and is not prone to jamming.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A reeling assembly includes a mounting rod, a sliding block, a lever, a first driving member, and two connecting rods. The mounting rod is horizontally arranged in the front-to-back direction. The sliding block is mounted on both the upper and lower ends of the mounting rod, and the sliding block can slide on the mounting rod in the front-to-back direction. A lever is slidably mounted on each sliding block in the left-to-right direction, and the lever can slide on the corresponding sliding block in the direction of action. A mounting seat protrudes from the middle of one side of the mounting rod, and a vertical through-hole extends from the side of the mounting seat away from the mounting rod. A rotating shaft is provided, and the first driving component is mounted on the mounting base and is connected to the rotating shaft for transmission. A horizontally arranged connecting rod is fixedly mounted at each end of the rotating shaft. One end of the connecting rod is fixedly connected to the rotating shaft, and the other end of the upper connecting rod is rotatably connected to the end of the upper lever near the mounting base. The other end of the lower connecting rod is rotatably connected to the end of the lower lever near the mounting base. The angle formed by the two connecting rods relative to the rotating shaft is a flat angle.

[0005] The beneficial effects of the above technical solution are as follows: it enables both the upper and lower levers of the mounting rod to move in two dimensions relative to the mounting rod under the drive of the first driving component (the lever slides backward while also sliding away from the mounting seat, or the lever slides forward while also sliding closer to the mounting seat), thereby achieving the periodic feeding of straw backward. The operating cycles of the upper and lower levers are staggered (when the upper lever slides backward, the lower lever slides forward), so that the upper and lower levers of the mounting rod alternately feed the straw backward, which can improve the operating efficiency of feeding straw.

[0006] The above technical solution also includes two connecting rods. The upper and lower ends of the mounting rod are each provided with two sliding seats at intervals along the front-back direction. The two connecting rods are both provided along the front-back direction and distributed at intervals along the vertical direction. The two connecting rods correspond one-to-one with the two linkage rods. The end of each linkage rod away from the rotating shaft is rotatably connected to the middle part corresponding to the length direction of the connecting rod. The ends of the two upper levers near the mounting seat are respectively connected to the two ends of the upper connecting rod. The ends of the two lower levers near the mounting seat are respectively connected to the two ends of the lower connecting rod.

[0007] The beneficial effects of the above technical solution are as follows: by setting two sliding blocks at the upper and lower ends of the mounting rod, the upper and lower ends of the mounting rod each have two levers distributed at intervals. The two levers at the top operate in the same manner, and the two levers at the bottom also operate in the same manner, but the operating states of the levers at the top and bottom are still opposite. At this time, multiple levers on the same mounting rod can realize four-stage feeding of straw from front to back, which further improves the feeding efficiency of straw.

[0008] The second objective of this invention is to provide a simple structure that effectively conveys millet stalks and is less prone to jamming.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows: a straw-pulling assembly, comprising two dividing stalks and two straw-pulling components as described above, the two straw-pulling components being spaced apart in the left-right direction, and the two mounting seats being located on the side of the two mounting stalks that are far apart from each other, the plurality of levers on the two straw-pulling components cooperating to push the straw between the two mounting stalks backward under the drive of the two first driving members; the two dividing stalks are respectively installed at the front ends of the two mounting stalks in the front-back direction, and the front ends of the two dividing stalks are respectively inclined to both sides to form an inverted "V" shape, the two dividing stalks being used to gather the straw between their front ends to the space between the two mounting stalks.

[0010] The beneficial effects of the above technical solution are as follows: the two reeling components are distributed relatively at intervals, and the straw is coordinated and conveyed backward by multiple reeling rods on both sides between the two components. The conveying efficiency is high and the straw is less likely to be lost. The two dividing rods can guide the straw in front of each reeling component to the space between the two reeling components, so as to avoid the reeling components squeezing the straw in front of them and causing it to fall over during the forward movement, thus affecting the subsequent harvesting.

[0011] The second objective of this invention is to provide a millet harvester with a simple structure that is specifically designed for harvesting millet and that threshes the millet stalks before cutting them during the harvesting process.

[0012] To achieve the above objectives, the technical solution of the present invention is as follows: A millet harvester includes a vehicle body, a threshing assembly, a screening assembly, a cutting assembly, a grain storage box, and a grain-reeling assembly as described above. The vehicle body has wheels on both sides, and a grain-passing channel is recessed upwards in the middle of the lower end of the vehicle body. The rear ends of two mounting rods are respectively connected to the front end of the vehicle body, and the two mounting rods are respectively located on both sides of the grain-passing channel. The threshing assembly is installed at the upper front end of the vehicle body, the cutting assembly is installed on the vehicle body and located within the grain-passing channel, and the screening assembly is arranged along the front-rear direction on the vehicle body. The upper end of the threshing assembly is located behind the threshing assembly. The threshing assembly has a discharge port, which is located above the end of the screening assembly. The grain storage box is installed at the rear end of the vehicle body. The grain discharge of the screening assembly is located above the opening of the grain storage box. The threshing assembly is used to thresh the ears of millet stalks at the upper end of the millet stalks conveyed by the millet-pulling assembly. The threshed stalks enter the millet-pulling channel and are cut and discharged by the millet-pulling assembly. The material in the threshing assembly is discharged through the discharge port to the screening assembly for screening. The screened millet is discharged through the grain discharge port into the grain storage box for storage.

[0013] The beneficial effects of the above technical solution are as follows: its structure is simple, so that when the vehicle body moves forward, the straw gathering assembly gathers the straw in front of the vehicle body towards the middle and pushes it backward, while the ears of grain at the top of the straw are directly threshed by the threshing assembly. The threshed straw enters the passing channel, is cut off by the cutting assembly, and thrown out. The material in the threshing assembly is screened by the screening assembly, and the selected millet after screening is collected by the grain storage box.

[0014] The threshing assembly described in the above technical solution includes a trough shell, a central shaft, a second drive unit, two rotating disks, and multiple threshing brush rollers. The trough shell is horizontally arranged at the upper front end of the vehicle body in the left-right direction, with its opening facing forward and upward. The discharge port is located at the lower rear end of the trough shell. The central shaft is horizontally arranged inside the trough shell in the left-right direction near its opening, and both ends of the central shaft are rotatably connected to the trough shell. The two rotating disks are coaxially fixedly mounted on the central shaft, and the two rotating disks are respectively close to both ends of the trough shell. The multiple threshing brush rollers are horizontally arranged between the two rotating disks in the left-right direction and are circumferentially spaced around the central shaft. Both ends of each threshing brush roller are rotatably connected to the two rotating disks. The two ends of the central shaft are close to the opposite end of the rotating disk. At the position of the rotating disk, a first gear is coaxially mounted and fixedly connected to the trough shell. Each of the threshing brush rollers has a second gear at each end that meshes with the corresponding first gear. The second driving member is mounted on the trough shell and is connected to the central shaft. The second driving member is used to drive the central shaft to drive the two rotating disks to rotate, thereby driving the multiple threshing brush rollers to revolve around the central shaft with the rotating disks. When the multiple threshing brush rollers revolve around the central shaft, the two second gears at both ends of the rollers rotate around the first gear and drive the rollers to rotate on their own axis. The ears of millet straw at the top are guided into the trough of the trough shell through the opening and are threshed under the action of the rotation and revolution of the multiple threshing brush rollers.

[0015] The beneficial effects of the above technical solution are as follows: By setting a central shaft and two turntables, with the turntables fixed to the central shaft, and the first gear rotating on the central shaft being fixed relative to the trough shell, and each threshing brush roller on the turntable being rotatably mounted on the two turntables and meshing with the first gear at its end, the turntable rotates relative to the trough shell under the drive of the second drive component of the central shaft. At the same time, multiple threshing brush rollers also rotate around the central shaft with the two turntables (i.e., the threshing brush rollers revolve around the central shaft). As the central shaft rotates, the central shaft and the first gear rotate relative to each other (but the first gear remains stationary relative to the entire vehicle body). Multiple second gears rotate on the turntable under the drive of the first gear and drive the threshing brush rollers to rotate relative to the turntable (at this time, the threshing brush rollers rotate relative to themselves). Since the ears of grain at the top of the straw will extend into the trough shell through the opening of the trough shell, multiple threshing brush rollers will both rotate and revolve under the drive of the first drive component, continuously brushing the ears of grain to thresh the millet on the ears of grain.

[0016] In the above technical solution, the lower end of the groove opening of the trough shell is provided with distribution grooves evenly spaced in the left and right direction. The multiple distribution grooves are comb-shaped at the groove opening of the trough shell, which are used to evenly distribute the millet straw conveyed by the millet assembly in the left and right direction at the groove opening of the trough shell.

[0017] The beneficial effects of the above technical solution are as follows: the distribution troughs limit the straw to prevent the ears of straw from being squeezed to both sides during the advance of the trough shell, thereby improving the threshing effect. At the same time, multiple distribution troughs can also ensure that the gathered straw is evenly distributed laterally at the front end of the trough shell, so that the ears of straw are evenly spread in the trough shell and threshed efficiently.

[0018] The screening assembly described in the above technical solution includes a screen plate and a belt conveyor. The screen plate is arranged in the front-to-back direction with its rear end inclined downwards. The belt conveyor is arranged below the screen plate in the front-to-back direction. The grain storage box is located below and behind the screen plate, and the discharge end of the belt conveyor is located at the trough of the grain storage box. The screen holes on the screen plate are all located in front of the grain storage box. The belt conveyor is used to receive the millet screened by the screen plate and transport it to the grain storage box. The screened impurities are discharged through the rear end of the screen plate.

[0019] The beneficial effect of the above technical solution is that the millet grains screened by the sieve plate are directly transported to the grain storage bin by the belt conveyor, while the impurities retained on the sieve plate slide backward along the sieve plate.

[0020] The above-described harvesting assembly includes a straw-tipping mechanism, a straw-cutting mechanism, and two gathering plates. The two gathering plates are vertically arranged and spaced apart on both sides of the front end of the rice passage in the left-right direction. The distance between the two gathering plates gradually decreases from front to back to form a figure-eight shape. The straw-tipping mechanism is arranged in the straw-tipping passage in the front-back direction and is located behind the two gathering plates. The straw-cutting mechanism is located at the lower front end of the straw-tipping mechanism. The two gathering plates are used to gather the straw pushed backward by the straw-tipping assembly towards the middle at the front end of the rice passage and transport it to the straw-tipping mechanism. The straw is cut by the straw-cutting mechanism. The cut straw is transported backward by the straw-tipping mechanism, and during the transport process, the straw is switched from an upright state to a horizontal state and thrown out.

[0021] The beneficial effects of the above technical solution are as follows: the gathering plate can guide the threshed straw to the inlet end of the straw-falling mechanism, and during this process, the straw-cutting mechanism cuts the gathered straw. The cut straw is then switched from a vertical state to a horizontal state by the straw-falling mechanism and thrown backward.

[0022] The straw-tipping mechanism described in the above technical solution includes a third driving component, two vertical shafts, two horizontal shafts, and two conveyor belts. The two vertical shafts, two horizontal shafts, and two conveyor belts correspond one-to-one. The two vertical shafts are vertically arranged and spaced apart in the left-right direction behind the two gathering plates. The two horizontal shafts are horizontally arranged in the left-right direction and spaced apart in the vertical direction. Both ends of the two vertical shafts and two horizontal shafts are rotatably connected to the vehicle body. A conveyor belt is fitted onto the corresponding vertical shaft and horizontal shaft and the conveyor belt is spread out. The same end of the two horizontal shafts is rotatably connected to the third driving component installed on the vehicle body. The side of the two conveyor belts that are close to each other is used to clamp the straw and transport the straw from front to back. During the transport process, the straw is switched from an upright state to a horizontal state.

[0023] The beneficial effect of the above technical solution is that the two vertical shafts and two horizontal shafts together spread and twist the corresponding two closely attached conveyor belts in the front-to-back direction by 90°, so that the straw is conveyed backward under the clamp of the two conveyor belts, and gradually switched from the vertical state to the horizontal state during the conveying process, thereby ensuring that the thrown straw is spread out in an orderly manner in the field.

[0024] The harvesting mechanism described in the above technical solution includes two cutter discs and two fourth drive components. The two cutter discs are horizontally arranged below the rear of the two vertical shafts and are spaced apart in the left-right direction. The cutter shafts of the two cutter discs are rotatably connected to the vehicle body. The two fourth drive components are mounted on the vehicle body and correspond one-to-one with the two cutter discs. The drive end of each fourth drive component is connected to the cutter shaft of the corresponding cutter disc.

[0025] The beneficial effect of the above technical solution is that it enables the two cutter heads to work together to cut the straw that is initially clamped by the two conveyor belts. Attached Figure Description

Detailed Implementation

[0043] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0044] Example 1

[0045] like Figures 1-4As shown, this embodiment provides a reeling assembly, including a mounting rod 111, a slide block 112, a lever 113, a first driving member 114, and two connecting rods 115. The mounting rod 111 is horizontally arranged in the front-back direction. The slide block 112 is mounted on both the upper and lower ends of the mounting rod 111, and the slide block 112 can slide on the mounting rod 111 in the front-back direction. The lever 113 is slidably mounted on each slide block 112 in the left-right direction, and the lever 113 can slide on the corresponding slide block 112 in the direction of action. A mounting seat 118 protrudes from the middle of one side of the mounting rod 111, and a lever is vertically inserted through the mounting seat 118 on the side away from the mounting rod 111. A rotating shaft 116 is provided. The first driving member 114 is mounted on the mounting base 118 and is connected to the rotating shaft 116 in a transmission manner. A horizontally arranged connecting rod 115 is fixedly mounted at each end of the rotating shaft 116. One end of the connecting rod 115 is fixedly connected to the rotating shaft 116. The other end of the upper connecting rod 115 is rotatably connected to the end of the upper lever 113 near the mounting base 118. The other end of the lower connecting rod 115 is rotatably connected to the end of the lower lever 113 near the mounting base 118. The angle formed by the two connecting rods 115 relative to the rotating shaft 116 is a straight angle (see details). Figure 4 As shown), this allows both the upper and lower levers of the mounting rod to move in two dimensions relative to the mounting rod under the drive of the first driving component (the lever slides backward while also sliding away from the mounting seat, or the lever slides forward while also sliding closer to the mounting seat), thereby achieving the periodic feeding of straw backward. The operating cycles of the upper and lower levers are staggered (when the upper lever slides backward, the lower lever slides forward), so that the upper and lower levers of the mounting rod alternately feed the straw backward, which can improve the operating efficiency of feeding straw.

[0046] like Figures 1-3As shown, the above technical solution also includes two connecting rods 117. Two sliding blocks 112 are spaced apart at the upper and lower ends of the mounting rod 111 along the front-to-back direction. The two connecting rods 117 are arranged along the front-to-back direction and distributed vertically at intervals. Each connecting rod 117 corresponds one-to-one with two connecting rods 115. The end of each connecting rod 115 away from the rotating shaft 116 is rotatably connected to the middle portion of the corresponding connecting rod 117 along its length direction. The ends of the two upper levers 113 near the mounting base 118 are respectively connected to the two ends of the upper connecting rod 117. The two lower levers... The end of the lever 113 near the mounting base 118 is connected to both ends of the connecting rod 117 located below. By setting two sliding seats at the upper and lower ends of the mounting rod, the upper and lower ends of the mounting rod each have two levers distributed at a distance. The two levers at the top operate in the same state, and the two levers at the bottom also operate in the same state. However, the operating states of the levers at the top and the levers at the bottom are still opposite. At this time, multiple levers on the same mounting rod can realize four-level feeding of straw in the feeding process from front to back, which further improves the feeding efficiency of straw.

[0047] In the above technical solution, the first driving component 114 is a motor, and the first driving component 114 is embedded in the mounting base 118. Its driving shaft faces upward or downward. Both the driving end of the first driving component 114 and the rotating shaft 116 are equipped with pulleys 1191, and the two pulleys 1191 are connected by a belt 1192. Its structure is simple and compact.

[0048] Example 2

[0049] like Figure 5 As shown, this embodiment provides a straw-pulling assembly, including two straw-pulling components 11 as described in Embodiment 1. The two straw-pulling components 11 are spaced apart in the left-right direction, and the two mounting seats 118 are located on the side of the two mounting rods 111 that are far apart from each other. The multiple levers 113 on the two straw-pulling components 11 work together under the drive of the two first driving members 114 to push the straw between the two mounting rods 111 backward. In this way, the two straw-pulling components are relatively spaced apart, and the straw is pushed backward by the multiple levers on both sides between them. The pushing efficiency is high and the straw is not easy to fall out.

[0050] The above technical solution also includes two dividing stalks 12, which are respectively installed at the front ends of the two mounting rods 111 in a front-back direction. The front ends of the two dividing stalks 12 are inclined to both sides to form an inverted "V" shape. The two dividing stalks 12 are used to gather the straw between their front ends to the two mounting rods 111. In this way, the two dividing stalks can guide the straw in front of each reeling component to the space between the two reeling components, so as to avoid the reeling components squeezing the straw in front of them and causing it to fall over during the forward movement, thus affecting the subsequent harvesting. Figure 5 The range between the two parallel dotted lines indicates the working width of the reel assembly during its forward movement.

[0051] In this embodiment, the four levers at the upper end are staggered in the front-to-back direction in the initial state (at the same time, the four levers at the lower end are also staggered in the front-to-back direction), and then the two first driving members keep running synchronously (with the same speed and opposite rotation directions).

[0052] Example 3

[0053] like Figure 6 and Figure 8As shown, this embodiment provides a millet harvester, including a vehicle body 2, a threshing assembly 3, a screening assembly 4, a cutting assembly 5, a grain storage box 6, and a grain-picking assembly 1 as described in Embodiment 2. The vehicle body 2 has wheels 21 on both sides. A grain-passing channel 22 is recessed upwards at the center of the lower end of the vehicle body 2. The rear ends of two mounting rods 111 are respectively connected to the front end of the vehicle body 2, and the two mounting rods 111 are respectively located on both sides of the grain-passing channel 22. The threshing assembly 3 is installed at the upper front end of the vehicle body 2. The cutting assembly 5 is installed on the vehicle body 2 and located within the grain-passing channel 22. The screening assembly 4 is arranged along the front-rear direction at the upper end of the vehicle body 2 and is located behind the threshing assembly 3. The threshing assembly 3 has a discharge port 311, which is located above the end of the screening assembly 4. The grain storage box 6 is installed on the vehicle body 2. At the rear end of the vehicle body 2, the discharge end of the screening assembly 4 is located above the opening of the grain storage box 6. The threshing assembly 3 is used to thresh the ears of millet stalks at the top of the millet stalks conveyed by the threshing assembly 1. The threshed stalks enter the passing channel 22 and are cut off by the cutting assembly 5 and discharged. The material in the threshing assembly 3 is discharged through the discharge port 311 to the screening assembly 4 for screening. The screened millet is discharged through the grain outlet to the grain storage box 6 for storage. Its structure is simple. In this way, when the vehicle body moves forward, the threshing assembly gathers the stalks in front of the vehicle body towards the middle and conveys them backward, while the ears of millet at the top of the stalks are directly threshed by the threshing assembly. The threshed stalks enter the passing channel, are cut off by the cutting assembly and thrown out, while the material in the threshing assembly is screened by the screening assembly, and the screened and selected millet is collected by the grain storage box.

[0054] In this embodiment, the wheels can be automatically driven tracked wheels (which are existing technologies and will not be described in detail here), and multiple tracked wheels can be provided on each side of the vehicle body.

[0055] like Figure 14 and Figure 15 As shown, the vehicle body 2 in the above technical solution also includes a frame 23. The frame 23 includes an upper frame 231 and two lower frames 232. The upper frame 231 and the two lower frames 232 are arranged along the front-rear direction. The two lower frames 232 are distributed at intervals along the left-right direction and are respectively arranged on both sides of the lower end of the upper frame 231. The area between the two lower frames 232 forms the grain passage 22. The two mounting rods 111 are respectively installed at the front end of the two lower frames 232. The structure is simple, so that a grain passage is created between the two lower frames, and the upper ends of the two lower frames are connected by the upper frame.

[0056] In the above technical solution, both the upper frame 231 and the lower frame 232 are hollow frames, and the screening assembly 4 is installed inside the upper frame 231. This reduces the weight of the entire frame and allows the screening assembly to be installed inside the upper frame, making the overall structure of the vehicle more compact and helping to reduce the vehicle height.

[0057] like Figures 9-12As shown, the threshing assembly 3 in the above technical solution includes a trough shell 31, a central shaft 32, a second drive component 33, two rotating disks 34, and multiple threshing brush rollers 35. The trough shell 31 is horizontally arranged at the upper front end of the vehicle body 2 in the left-right direction, with its trough opening facing forward and upward. The discharge port 311 is located at the lower rear end of the trough shell 31. The central shaft 32 is horizontally arranged inside the trough shell 31 in the left-right direction near its trough opening, and both ends of the central shaft 32 are rotatably connected to the trough shell 31. The two rotating disks 34 are coaxially fixedly mounted on the central shaft 32, and the two rotating disks 34 are respectively close to both ends of the trough shell 31. The multiple threshing brush rollers 35 are arranged in the left-right direction. The threshing brush rollers 35 are horizontally positioned between two rotating disks 34 and circumferentially spaced around the central axis 32. Each threshing brush roller 35 has two ends rotatably connected to the two rotating disks 34. At each end of the central axis 32, near the corresponding rotating disk 34, a first gear 36 is coaxially mounted and fixedly connected to the trough shell 31. Each end of each threshing brush roller 35 has a second gear 37 meshing with the corresponding first gear 36. A second driving member 33 is mounted on the trough shell 31 and is drively connected to the central axis 32. The second driving member 33 drives the central axis 32 to rotate the two rotating disks 34, thereby driving multiple threshing brush rollers. The threshing brush rollers 35 revolve around the central axis 32 along with the rotating disk 34. As the multiple threshing brush rollers 35 revolve around the central axis 32, the two second gears 37 at both ends rotate around the first gear 36, driving the threshing brush rollers 35 to rotate. The ears of millet straw at the top are guided into the groove of the trough shell 31 through the opening and are threshed under the rotation and revolution of the multiple threshing brush rollers 35. This is achieved by setting a central axis and two rotating disks, with the rotating disks fixed to the central axis. The first gear rotating on the central axis is fixed relative to the trough shell, and each threshing brush roller on the rotating disk is rotatably mounted on the two rotating disks, meshing with the first gear at its end through the second gear. Driven by the second drive unit, the central shaft drives the turntable to rotate relative to the trough shell. At this time, multiple threshing brush rollers also rotate around the central shaft along with the two turntables (i.e., the threshing brush rollers revolve around the central shaft). As the central shaft rotates, it rotates relative to the first gear (but the first gear remains stationary relative to the entire vehicle body). At this time, multiple second gears rotate on the turntable under the drive of the first gear and drive the threshing brush rollers to rotate relative to the turntable (at this time, the threshing brush rollers rotate relative to themselves). Since the ears of grain at the top of the straw will extend into the trough shell through the opening, the multiple threshing brush rollers will both rotate and revolve under the drive of the first drive unit, continuously brushing the ears of grain to thresh the millet on the ears of grain.

[0058] Preferably, in this embodiment, notches 313 for mounting the turntable can be reserved on both sides of the trough shell 31. The turntable can be located in the notches 313, and support columns 314 can be set at both ends of the central shaft to support the central shaft. The central shaft is rotatably connected to the support columns, and the lower end of the support column 314 is fixedly connected to the lower end of the trough shell 31. The turntable can be a grooved disc, and the grooves of the two turntables are opposite to each other. The first gear and the second gear at both ends of the central shaft and the threshing brush roller are respectively located in the grooves of the corresponding turntables, and the first gear is fixedly connected to the corresponding support column. The second driving component is a motor (specifically, a geared motor can be used), and the second driving component is mounted on any one of the support columns, and its driving end is connected to the corresponding end of the central shaft.

[0059] In the above technical solution, the lower end of the trough shell 31 at the trough opening is provided with distribution grooves 312 evenly spaced along the left and right direction. The multiple distribution grooves 312 are comb-shaped at the trough opening of the trough shell 31. They are used to evenly distribute the millet straw conveyed by the millet assembly 1 at the trough opening of the trough shell 31 along the left and right direction. In this way, the distribution grooves limit the straw to prevent the ears of straw from being squeezed to both sides during the advance of the trough shell, thereby improving the threshing effect. At the same time, the multiple distribution grooves can also ensure that the gathered straw is evenly distributed laterally at the front end of the trough shell, so that the ears of grain are evenly spread in the trough shell and threshed efficiently.

[0060] In this embodiment, there may be 5-10 threshing brush rollers, and each threshing brush roller is evenly covered with bristles, which may be steel wire bristles.

[0061] In this embodiment, the trough opening side of the trough shell is tilted upward at an angle of 5-10°, which allows the material inside the trough shell to slide backward and be discharged through the outlet. The lower end of the trough opening side of the trough shell (i.e., the location where the distribution trough is set) is slightly raised upward (the angle of the raised part is 2-5° relative to the lower end of the trough shell, so that when the ears of grain on the straw are separated from the trough shell, the distribution trough can scrape off the remaining grains on the ears of grain, which can further improve the threshing effect).

[0062] In this embodiment, the distribution grooves are all V-shaped grooves, that is, the groove width gradually narrows from front to back.

[0063] like Figure 6 and Figure 7As shown, the screening assembly 4 in the above technical solution includes a screen plate 41 and a belt conveyor 42. The screen plate 41 is arranged in the front-to-back direction, and its rear end is inclined downward. The belt conveyor 42 is arranged in the front-to-back direction below the screen plate 41. The grain storage box 6 is located below and behind the screen plate 41, and the discharge end of the belt conveyor 42 is located at the trough of the grain storage box 6. The screen holes on the screen plate 41 are all located in front of the grain storage box 6. The belt conveyor 42 is used to receive the millet grains screened by the screen plate 41 and transport them backward to the grain storage box 6. The screened impurities are discharged through the rear end of the screen plate 41. In this way, the millet grains screened by the screen plate are directly transported to the grain storage box by the belt conveyor, while the impurities retained on the screen plate slide backward along the screen plate (wherein, Figure 7 The dashed line represents the trajectory of the debris being discharged backwards from the sieve plate. Figure 7 The solid arrow inside the grain storage bin indicates the trajectory of millet grains being discharged into the bin by the belt conveyor.

[0064] In this embodiment, the front end and both sides of the sieve plate are turned upward to form a baffle. The inclination angle of the sieve plate can be 5-10°. The upper front end of the sieve plate has a sieve screen at the position with sieve holes, while the rear end of the sieve plate has no sieve holes (it only serves to send the debris on the sieve plate backward).

[0065] In this embodiment, to improve the screening effect of the screen plate, the screen plate can be mounted on the vehicle body with multiple springs in a vibration damping manner, and a vibration motor can be set on the screen plate to increase the vibration force of the screen plate, thus improving its screening effect (the vibration motor can be set at the front end of the screen plate). This is a conventional technology in the field of vibrating screens and will not be described in detail here. In this embodiment, the conveyor belt of the belt conveyor can be a toothed conveyor belt made of rubber.

[0066] like Figures 13-16As shown, the harvesting assembly 5 in the above technical solution includes a rice-falling mechanism 51, a rice-cutting mechanism 52, and two gathering plates 53. The two gathering plates 53 are vertically arranged and spaced apart on both sides of the front end of the rice-passing channel 22 in a left-right direction, with the distance between the two gathering plates 53 gradually decreasing from front to back to form a figure-eight shape. The rice-falling mechanism 51 is arranged in the rice-falling channel in a front-back direction and is located behind the two gathering plates 53. The rice-cutting mechanism 52 is located at the lower front end of the rice-falling mechanism 51. The two gathering plates 53 are used for... The straw, pushed backward by the reeling assembly 1, is gathered towards the center at the front end of the passing channel 22 and conveyed to the straw-falling mechanism 51. The straw-cutting mechanism 52 then cuts the straw. The cut straw is conveyed backward by the straw-falling mechanism 51, and during this conveying process, the straw is switched from an upright state to a horizontal state and thrown out. In this way, the gathering plate guides the threshed straw towards the inlet of the straw-falling mechanism. During this process, the cutting mechanism cuts the gathered straw, and the straw-falling mechanism switches the cut straw from an upright state to a horizontal state and throws it backward. Figure 16 The arrow in the center at the front is a schematic diagram showing the upright straw being fed into the straw-feeding mechanism; Figure 16 The arrows between the straw-feeding mechanism and the grain storage bin represent the trajectory of the straw discharge after the separation.

[0067] The above-described technical solution describes a rice-tipping mechanism 51 comprising a third driving component 511, two vertical shafts 512, two horizontal shafts 513, and two conveyor belts 514. Each of the two vertical shafts 512, two horizontal shafts 513, and two conveyor belts 514 corresponds to a specific component. The two vertical shafts 512 are vertically oriented and spaced apart in the left-right direction behind the two gathering plates 53. The two horizontal shafts 513 are horizontally oriented in the left-right direction and spaced apart vertically. Both ends of the two vertical shafts 512 and two horizontal shafts 513 are rotatably connected to the vehicle body 2. A conveyor belt 514 is fitted onto each corresponding vertical shaft 512 and horizontal shaft 513. 14. The two horizontal shafts 513 are rotatably connected at the same end to the third drive component 511 mounted on the vehicle body 2. The two conveyor belts 514 are close to each other on one side to clamp the straw and convey the straw from front to back. During the conveying process, the straw is switched from an upright state to a horizontal state. In this way, the two vertical shafts and the two horizontal shafts together open and twist the corresponding two closely attached conveyor belts in the front-back direction by 90°, so that the straw is conveyed backward under the clamping of the two conveyor belts and gradually switched from an upright state to a horizontal state during the conveying process, thereby ensuring that the thrown straw is spread out in an orderly manner in the field (the width of the conveyor belt in this embodiment can be 20-40cm).

[0068] In this embodiment, the third driving component is a motor. A third gear is installed at one end of each of the two horizontal shafts, and the two third gears mesh with each other. The third driving component can be connected to the corresponding end of any one of the horizontal shafts for transmission. At this time, the third driving component drives the two horizontal shafts to rotate, and the rotation directions of the two horizontal shafts are opposite (the side of the two conveyor belts that are close to each other moves from front to back).

[0069] The cutting mechanism 52 described in the above technical solution includes two cutter discs 521 and two fourth drive members 522. The two cutter discs 521 are horizontally arranged below the rear of the two vertical shafts 512, and the two cutter discs 521 are spaced apart in the left-right direction. The cutter shafts 5211 of the two cutter discs 521 are rotatably connected to the vehicle body 2. The two fourth drive members 522 are mounted on the vehicle body 2 and correspond one-to-one with the two cutter discs 521. The drive end of each fourth drive member 522 is connected to the cutter shaft 5211 of the corresponding cutter disc 521, so that the two cutter discs cooperate to cut the straw initially clamped by the two conveyor belts.

[0070] The fourth driving component 522 is a motor. The two cutter discs are driven by independent fourth driving components, which is beneficial for the cut straw stubble to spread between the two fourth driving components and return to an upright state.

[0071] Preferred, such as Figure 6 As shown, the millet harvester in this embodiment may also include a height adjustment component 7. The trough shell is installed at the upper front end of the vehicle body through the height adjustment component 7. At this time, the height adjustment component 7 can be used to adjust the height of the threshing assembly to meet the harvesting needs of millet varieties with different plant heights.

[0072] In this embodiment, the height adjustment component can be a double scissor-type electric lifting platform, or multiple vertically arranged telescopic cylinders can be used to install the threshing assembly on the vehicle body. In this case, the multiple telescopic cylinders extend and retract to adjust the height of the threshing assembly.

Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
