Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and in particular relates to a grain harvesting and baling machine. Background Art

[0002] Cereal straw is an important agricultural renewable resource, and its utilization value is receiving increasing attention. In particular, the demand for fodder in the livestock industry in northern China is constantly increasing, and the utilization of cereal straw as feed is relatively urgent. In recent years, the promotion of wheat-cotton intercropping has been strengthened. However, the track gauge of existing grain harvesters is narrow, which crushes the cotton seedlings. The crushing device crushes the straw discharged by the threshing unit and buries the cotton seedlings after it falls to the ground, affecting the growth of the cotton seedlings. In response to this, new requirements have been proposed: (1) When harvesting wheat, keep a 10-15cm stubble and do not cut the heads of the cotton seedlings; (2) When harvesting, collect wheat straw, and do not pack the straw that falls to the ground without crushing the cotton seedlings.

[0003] Currently, grain straw recovery is primarily carried out using towed balers, with a smaller number of self-propelled balers. These machines are used for secondary field baling after the grain combine harvester has completed its operation. This not only compacts the soil, increasing its destructiveness, but also wastes resources and increases operating costs. Furthermore, directly crushing and returning grain straw to the field can result in the straw becoming difficult to rot or heating up, which can damage newly planted seeds and affect germination rates. Furthermore, soil microorganisms can breed pathogens, hindering grain growth. Currently, relevant companies have developed integrated grain harvesting and baling machines that synchronize grain harvesting with straw baling. This not only reduces the number of agricultural machines but also makes the bales cleaner and easier to process.

[0004] Prior art, published as CN114568112A, discloses a bottom-feed, rear-mounted integrated harvester and baler. This machine uses an inclined plate to guide material discharged from the threshing device's grass outlet into a conveyor roller assembly with raised surfaces. The conveyor roller assembly conveys the material horizontally. The raking steel bars and the pulling teeth work together to push the material upward into the baling chamber. A reciprocating piston compression mechanism continuously presses the material into the baling chamber, where it is then tied and bundled. This feeding method has the following disadvantages: when the harvester is fed a large amount of material, clogging can easily occur at the baling mechanism, significantly reducing the machine's operating efficiency. Furthermore, due to insufficient power input to the baling mechanism and an insufficiently long baling chamber, the bales are low in density and prone to warping.

[0005] Another example is the prior art, which has a publication number of CN108207333A, which discloses a top-feeding, rear-mounted, fast-feeding baler. The side of the fast-feeding baler is provided with a sloped feed port connected to the material discharge port of the harvester. The discharged material is transported to the material drop channel by a spiral auger. The material pressing actuator performs preliminary compression on the material, and the reciprocating piston compression mechanism continuously presses the material into the baling chamber. The knotting and baling components complete the subsequent baling. The disadvantage of this feeding method is that the material falls freely. When the amount of grass discharged is large, it is easy for the material to accumulate at the feed port, affecting the subsequent baling operation. A crank-connecting rod mechanism is used to drive the pressing cone to squeeze the material. Since the contact area between the pressing cone and the material is small and the squeezing capacity is weak, it will lead to uneven density of the bales and reduce the baling rate.

[0006] Another example is a top-feed, rear-mounted harvester-baler disclosed in CN110476589A. In this harvester-baler, material discharged from the threshing unit falls directly into a feed channel. Two sets of sequentially operating material forks push the material into a push channel. A reciprocating piston compression mechanism continuously presses the material into the bale chamber, where it is then tied and bundled. This baling method reduces the length of the bale chamber to avoid a top-light, foot-heavy situation, resulting in low bale density.

[0007] The problems with the existing technology are:

[0008] 1. Low operating efficiency: The material is freely dropped from the threshing device outlet, which results in poor material flow. When the harvester feeds a large amount of material, it is prone to blockage when feeding the baling device, significantly reducing the machine's operating speed.

[0009] 2. The input power of the baling device is insufficient and the compression chamber is not long enough, resulting in low bale density;

[0010] 3. Not suitable for wheat grain and grass harvesting under the wheat-cotton intercropping model. Summary of the Invention

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention achieves synchronous grain harvesting and material baling by arranging a horizontal baling device at the rear of the harvester, effectively improving work efficiency. The material discharged from the tail of the longitudinal axial flow threshing component of the present invention is passed through the roller-type blanking conveyor belt of the longitudinal material receiving device and the spiral material-feeding teeth, which greatly improves the fluidity of the material, speeds up the speed of the material entering the material box, and avoids the accumulation of material at the grass discharge port of the threshing device.

The present invention is provided with a flip-type extended baling chamber, which can not only solve the problem of loose bales due to insufficient bale extrusion force caused by the main baling chamber being too short, but also keep the baling device within a safe width range. The design is ingenious and safe and reliable.

The present invention can effectively solve the problem of material clogging from the grass discharge port of the threshing device to the horizontal baling device, and the material flows smoothly in the horizontal baling device, and the operating speed of the harvester and baler is not affected. Therefore, the machine has the same operating efficiency as a conventional harvester, and the bale density meets industry standards. The present invention can complete the harvesting and baling of grains in the wheat-cotton intercropping mode. By providing a quickly detachable seedling protection plate with an arc-shaped flange at the front under the blade guard of the cutting table, the cotton seedlings are effectively protected from direct contact and damage by the cutting table knives, thereby improving the degree of protection of the cotton seedlings during mechanical harvesting and reducing losses and waste. The present invention can complete the control of the landing position of the straw bale in the wheat-cotton intercropping mode. By setting the length of the baling chamber and the length of the straw bale to be extended, the straw bale can be dropped on the harvested wheat row without pressing the cotton seedlings.

Effects other than the above can be clearly seen and extracted from the description of the specification, drawings, claims, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] Combine Figure 11-19 The horizontal baling device 4 includes a longitudinal material receiving device 41, a transverse material feeding mechanism 42, a vertical filling device 43, a transverse compression device 44, a knotting and bundling component 45, a main bundling chamber 46, a timing protection mechanism 47, a bundling transmission system 48, and an extended bundling chamber 49; viewed from the rear, the longitudinal material receiving device 41 is arranged at the rear of the longitudinal axial flow threshing component 3 and in front of the transverse material feeding mechanism 42; one end of the longitudinal material receiving device 41 is connected to the other end of the longitudinal axial flow threshing component 3, and the longitudinal material receiving device 41 is connected to the longitudinal axial flow threshing component 3. The other end is connected to one end of a transverse feeding mechanism 42; the transverse feeding mechanism 42 is arranged in the upper left portion of the main bundling chamber 46, and the other end of the transverse feeding mechanism 42 is connected to one end of a vertical filling device 43; the vertical filling device 43 is arranged in the upper middle portion of the main bundling chamber 46, the transverse compression device 44 is arranged in the left portion of the main bundling chamber 46, the knotting and bundling component 45 is arranged in the upper right portion of the main bundling chamber 46, one end of the extended bundling chamber 49 is connected to the other end of the main bundling chamber 46, and the other end of the extended bundling chamber 49 is open. The transverse feeding mechanism 42 is used to receive material output from the longitudinal material receiving device 41, the vertical filling device 43 is used to vertically squeeze the material into the main bundling chamber 46, the transverse compression device 44 is used to reciprocally compress the material from the vertical filling device 43, the knotting and bundling component 45 is used to bundle the material into bales, and the extended bundling chamber 49 is used to squeeze the material and then discharge it.

[0075] In a specific embodiment of the present invention, the longitudinal material receiving device 41 is arranged at the tail of the longitudinal axial flow threshing component 3 and in front of the transverse feeding mechanism 42 when viewed from the tail. The transverse feeding mechanism 42 is arranged in the upper left part of the main bale chamber 46 to receive the material output from the longitudinal material receiving device 41. The vertical filling device 43 is arranged in the middle and upper part of the main bale chamber 46 to vertically squeeze the material into the main bale chamber 46. The transverse compression device 44 is arranged in the left part of the main bale chamber 46 to reciprocate and compress the material from the vertical filling device 43. The knotting and bundling component 45 is arranged in the upper right part of the main bale chamber 46. After the material is compressed to a certain length, it is tied into bales with a rope by the knotting and bundling component 45, discharged from the flip-type extended bale chamber 49, and dropped onto the harvested wheat rows. The timing protection mechanism 47 protects the horizontal baling device 4.

[0076] Preferably, the chassis 6 is a wide-gauge crawler chassis. Conventional structures such as the wide-gauge crawler chassis 6, the inclined conveying device 7, the longitudinal axial flow threshing component 3, the cleaning component 5, the grain tank 2, and the cab 1 can all be selected from related structures in the prior art, and the conventional structural parts will not be described here one by one.

[0077] The main working parts of the inclined conveying device 7 include a conveyor chain, active rollers, passive rollers, etc. The wide-gauge crawler chassis 6 is a self-propelled crawler structure, and its main working parts include drive wheels, guide wheels, tensioning wheels, and transmission tracks, etc. The grains in the longitudinal axial flow threshing component 3 fall into the cleaning component 5 and are then sent to the grain box 2. The materials are discharged from the tail of the longitudinal axial flow threshing component 3 to the horizontal baling device 4. The main working parts of the knotting and bundling component 45 include a knotter, a clutch, a needle threader, a star wheel, a star wheel shaft, a swing arm, and an arc-shaped rack, etc. The knotting and bundling component 45 bundles the materials in the main bundling chamber 46 into bales with baling ropes, discharges them from the flip-type extended bundling chamber 49, and drops the bales onto the harvested wheat rows.

[0078] like Figure 20-23 As shown, the main components of the header 8 include a seedling protection plate 81, a reel 82, a grain divider 83, a cutting knife 84, a blade guard 85, and a header auger 86. The reel 82, in cooperation with the grain divider 83, pushes the grain into the header. After being cut by the cutting knife 84, the grain is sent to the inclined conveying device 7 by the header auger 86. The inclined conveying device 7 sends the grain into the longitudinal axial flow threshing unit 3.

[0079] A plurality of quickly detachable seedling protection plates 81 are provided below the blade guard 85 of the cutting table 8. The front portion of the seedling protection plates 81 has an arc-shaped upward flange that does not damage the cotton seedlings. In the wheat-cotton intercropping mode, the number of seedling protection plates 81 is two, and the center distance between the two seedling protection plates 81 is equal to the cotton row spacing. By providing the seedling protection plates 81 with an arc-shaped upward flange at the front portion, the contact area between the seedling protection plates 81 and the cotton seedlings is minimized, friction and damage to the cotton seedlings is reduced, and the cotton seedlings are prevented from being "shaved" by the cutter 84 when the stubble is low. This improves the degree of protection for the cotton seedlings during the grain harvesting process and reduces losses and waste. In addition, the center distance between the two seedling protection plates 81 is equal to the cotton row spacing, which ensures that each row of cotton seedlings can be completely covered and protected, and the cutter 84 is prevented from causing damage to the cotton seedlings.

[0080] like Figure 24-27 As shown, the longitudinal material receiving device 41 includes a blanking conveyor belt 4103 and a spiral material-dividing tooth 4105; the blanking conveyor belt 4103 is installed at the lower edge of the grass discharge port 31 of the longitudinal axial flow threshing component 3, and the spiral material-dividing tooth 4105 is located above the tail of the blanking conveyor belt 4103. The blanking conveyor belt 4103 and the spiral material-dividing tooth 4105 work together to feed the blanking material into the horizontal feeding mechanism 42.

[0081] The longitudinal feeder 41 comprises a roller-type feed conveyor belt 4103 positioned at the lower edge of the grass discharge opening 31 of the longitudinal axial threshing unit 3, a spiral feeder tooth 4105 positioned above the rear end of the roller-type feed conveyor belt 4103, and a mounting plate assembly. The minimum distance between the outer edge of the spiral feeder tooth 4105 and the roller-type feed conveyor belt 4103 is equal to the maximum grass discharge layer thickness. The roller-type feed conveyor belt 4103 and the spiral feeder tooth 4105 work together to deliver the feed into the feed box 4201, where the transverse feed mechanism 42 resides. The material is transported through the drop conveyor belt 4103 connected to the grass discharge port 31 of the threshing device. When the amount of grass discharged is large or the horizontal feeding mechanism 42 blocks the material from entering the material box 4201 normally, the spiral material-picking teeth 4105 move the material accumulated above the drop conveyor belt 4103. Compared with the harvester and baler currently on the market in which the material freely falls from the grass discharge port of the threshing device, this design can greatly improve the fluidity of the material, speed up the speed at which the material enters the material box, and avoid the accumulation of material at the grass discharge port of the threshing device.

[0082] The mounting plate assembly includes a blanking channel cover 4101, blanking conveyor belt side panels 4104, blanking conveyor belt bottom panel 4106, and blanking conveyor belt transition panel 4102. A spiral feeder gear 4105 is mounted on the blanking channel cover 4101. A belt roller power input shaft 4828 and a belt roller power output shaft 4829 are mounted on the blanking conveyor belt side panels 4104. The belt roller power input shaft 4828 is mounted on one end with a feeder gear driving sprocket 4813, and on the other end with a belt roller power input sprocket 4815. A feeder gear driven gear 4811 is mounted on the spiral feeder gear 4105. The belt roller power input sprocket 4815 drives the belt roller power input shaft 4828 to rotate, which in turn drives the roller blanking conveyor belt 4103 between it and the belt roller power output shaft 4829. Simultaneously, the belt roller power input shaft 4828 drives the feeder gear driving sprocket 4813 to rotate. The stripper gear driving sprocket 4813 transmits power to the stripper gear driven sprocket 4811 through a chain. The stripper gear driven sprocket 4811 transmits power to the coaxially mounted stripper gear driving gear 4812, which meshes with the stripper gear driven gear 4811 to drive the spiral stripper gear 4105 to rotate.

[0083] The mounting plate assembly supports and secures the blanking conveyor belt and related components. Material discharged from the longitudinal axial flow threshing unit 3 is conveyed via the roller blanking conveyor belt 4103 to the feed bin 4201. The spiral feed teeth 4105 feed material accumulated above the roller blanking conveyor belt 4103 into the feed bin 4201. The combined action of the roller blanking conveyor belt 4103 and the spiral feed teeth 4105 significantly improves material flowability, accelerating the flow of material into the feed bin 4201 and preventing accumulation at the threshing device's grass discharge port 31. The blanking conveyor belt transition plate 4102 extends into the feed bin 4201, smoothly guiding material from the roller blanking conveyor belt 4103 into the feed bin 4201. Two notches are provided on the blanking conveyor belt base plate 4106, which not only dissipate heat generated by the rapid movement of the material but also prevent material from becoming entangled on the roller blanking conveyor belt 4103.

[0084] like Figures 28-30 As shown, the transverse feeding mechanism 42 includes a material box 4201, a gear box 4216 disposed within the material box 4201, and a feeding execution assembly. The material box 4201 includes a receiving chamber U-plate 4209 and a receiving chamber observation plate 4210. The receiving chamber observation plate 4210 is mounted at one end of the receiving chamber U-plate 4209. The other end of the receiving chamber U-plate 4209 is open and communicates with the vertical filling device 43. The open side of the receiving chamber U-plate 4209 is connected to the longitudinal feeding device 41. The receiving chamber U-plate 4209 is mounted with a diamond-shaped bearing seat 4207, a square bearing seat 4211, and a square bearing seat connecting plate 4212. The gear box 4216 is mounted with an elliptical planetary gear train, which includes a central elliptical gear 4213, an intermediate elliptical gear 4214, planetary elliptical gears 4215, a transverse feeding power input shaft 4217, and a planetary gear shaft 4204. One end of the planetary gear shaft 4204 is hinged to the material feeding support plate 4208, and the other end is keyed to the planetary elliptical gear 4215. One end of the transverse feed power input shaft 4217 is keyed to the transverse feed double-row sprocket 4819, and the other end is keyed to the central elliptical gear 4213. The material feeding support plate 4208 is hinged to the diamond-shaped bearing seat 4207 via the material feeding support shaft 4206.

[0085] The double-row lateral feed sprocket 4819 transmits power to the coaxially mounted central elliptical gear 4213. The intermediate elliptical gear 4214 meshes with the central elliptical gear 4213 and the planetary elliptical gears 4215, respectively, driving the planetary gear shaft 4204 to rotate. The epicyclic motion of the planetary gear train drives the feed actuator mounted on the planetary gear shaft 4204 to operate.

[0086] The material feeding support shaft 4206, diamond-shaped bearing seat 4207, material feeding support plate 4208, material receiving chamber U-plate 4209, square bearing seat 4211, and square bearing seat connecting plate 4212 are used to support and fix the feeding execution assembly and related components. The material in the material box 4201 is fed into the stuffing box 4301 by the feeding execution assembly. During the rotation of the elliptical gear planetary gear train, the motion trajectory of the planetary elliptical gear 4215 exhibits a "swinging" motion state. Through this "swinging" motion, the special motion trajectory of the feeding execution assembly can be achieved. A glass window is provided on the material receiving chamber observation plate 4210, allowing the operator to observe the working status of the feeding execution assembly in the material box 4201.

[0087] The feeding execution component includes a planetary gear shaft lug 4203, a front material-diverting claw 4205 and a rear material-diverting claw 4202; the planetary gear shaft lug 4203 is connected to the planetary gear shaft 4204 of the gear box 4216; the front material-diverting claw 4205 is connected to the planetary gear shaft lug 4203, and the rear material-diverting claw 4202 is connected to the front material-diverting claw 4205; the front material-diverting claw 4205 is a straight claw, and the rear material-diverting claw 4202 is a curved claw.

[0088] In one embodiment of the present invention, the front claw 4205 contacts the material first, so it is designed as a straight claw to improve the material discharging ability. The rear claw 4202 mainly performs the pushing function, so it is designed as a curved claw. The feeding actuator is designed to be four groups. If the material volume is small, the number of feeding actuator groups can be appropriately reduced; if the material volume is large, the number of feeding actuator groups can be appropriately increased. However, too densely installed feeding actuators will lead to a poor feeding process and increase the load; therefore, an appropriate number of feeding actuators should be installed.

[0089] like Figures 31-36 As shown, the vertical filling device 43 includes a filling box 4301 and a crank rocker and a filling execution assembly arranged in the filling box 4301; the crank rocker includes a filling crank 4303 and a filling connecting rod 4304.

[0090] The stuffing box 4301 includes a side baffle 4306 , a stuffing chamber observation plate 4322 and a stuffing chamber U-plate 4323 ; the side baffle 4306 is located on one side of the stuffing chamber U-plate 4323 , and the stuffing chamber observation plate 4322 is located on the other side of the stuffing chamber U-plate 4323 .

[0091] The filling execution assembly includes a fixed plate 4305, a movable plate 4310 and a scissor-fork mechanism; the fixed plate 4305 is connected to the filling box 4301, and the fixed plate 4305 and the movable plate 4310 are respectively provided with a guide rail 4309 and a support 4313, one side of the upper part of the scissor-fork mechanism is connected to the support 4313 of the fixed plate 4305, and the other side is slidably connected to the guide rail 4309 of the fixed plate 4305; one side of the lower part of the scissor-fork mechanism is connected to the support 4313 of the movable plate 4310, and the other side is slidably connected to the guide rail 4309 of the movable plate 4310; one end of the filling crank 4303 is connected to the transmission mechanism, and the other end is hinged to one end of the filling connecting rod 4304, and the other end of the filling connecting rod 4304 is hinged to the scissor-fork mechanism, and the transmission mechanism is connected to the driving mechanism, and the filling connecting rod 4304 is driven by the filling crank 4303 to make the scissor-fork mechanism extend and retract.

[0092] In one embodiment of the present invention, a partition plate 4302, a fixed plate 4305, and a first circular bearing seat 4320 are provided on the packing chamber U-plate 4323. One end of the partition plate 4302 is fixed to the packing chamber U-plate 4323, and the other end is fixed to the fixed plate 4305. A second circular bearing seat 4321 is mounted on the partition plate 4302, and a vertical packing power input shaft 4314 is hingedly connected to the second circular bearing seat 4321.

[0093] The vertical filling device 43 also includes a guide tube 4308 and a guide column 4307; the guide tube 4308 is connected to the fixed plate 4305, one end of the guide column 4307 passes through the guide tube 4308 and is connected to one end of the side baffle 4306 of the filling box 4301, and the other end of the guide column 4307 and the other end of the side baffle 4306 are respectively connected to the movable plate 4310; the guide column 4307 can slide vertically back and forth along the guide tube 4308.

[0094] The side baffle 4306 on the movable plate 4305 blocks the material in the material box 4201 where the transverse feeding mechanism 42 is located when the movable plate 4305 is at the lowest position, and at the same time the movable plate 4305 presses the material into the main bundling chamber 46; when the movable plate 4305 is at the uppermost position, the transverse feeding mechanism 42 is allowed to feed the material into the stuffing box 4301.

[0095] In a specific embodiment of the present invention, the scissor-type fork mechanism includes a first-stage scissor-type fork central axis 4315 , a second-stage scissor-type fork central axis 4316 , a hinge shaft 4317 , a first-stage fork rod 4318 and a second-stage fork rod 4319 .

[0096] In one embodiment of the present invention, the guide tube 4308 is fixed to the fixed plate 4305. One end of the guide column 4307 is fixed to the movable plate 4310, and the other end is fixed to the side baffle 4306. The packing connecting rod 4304 is hinged to the packing crank 4303 at one end and to the first-stage scissor center shaft 4315 at the other end. The vertical packing power input shaft 4314 is keyed to the vertical packing power input sprocket 4806 at one end and hinged to the packing crank 4303 at the other end.

[0097] In one embodiment of the present invention, the guide rail 4309 is a guide rail with slots for rolling bearings 4312. There are four guide rails 4309, two of which are fixed to the fixed plate 4305, and the remaining two are fixed to the movable plate 4310 via rectangular tubes 4311. There are four supports 4313, two of which are fixed to the fixed plate 4305, and the remaining two are fixed to the movable plate 4310. The first-stage fork rod 4318 is hinged to the second-stage fork rod 4319 through the hinge shaft 4317; there are four first-stage fork rods 4318, two of which are hinged to the rolling bearing 4312, and the remaining two first-stage fork rods 4318 are hinged to the support 4313; there are four second-stage fork rods 4319, two of which are hinged to the rolling bearing 4312, and the remaining two second-stage fork rods 4319 are hinged to the support 4313.

[0098] The vertical packing power input sprocket 4806 transmits power to the packing crank 4303 via the vertical packing power input shaft 4314. The packing crank 4303 drives the packing connecting rod 4304, which in turn drives the packing actuator. The packing actuator rolls on the guide rail 4309 via the rolling bearing 4312, driving the moving plate 4310, the side baffle 4306, and the guide column 4307 to perform vertical reciprocating motion.

[0099] The partition plate 4302, support 4313, first circular bearing seat 4320, and second circular bearing seat 4321 are used to support and secure the packing actuator and related components. The material in the packing box 4301 is pressed into the main bundling chamber 46 by the movable plate 4310 driven by the packing actuator. The packing crank 4303 and packing connecting rod 4304 are mounted in opposing positions to enhance structural stability and improve compression capacity. The guide column 4307 guides and constrains the movable plate 4310 and side baffles 4306, ensuring the accuracy and stability of their motion trajectory and position.

[0100] The scissor mechanism, in conjunction with guide posts 4307, synchronizes the movement of the side baffles 4306 and the movable plate 4310 driven by the filler actuator. When the filler connecting rod 4304 drives the scissor mechanism to push the movable plate 4310 downward, compressing the material, the side baffles 4306 follow the movable plate 4310 downward along the guide posts 4307, blocking the material from the material bin 4201 while the movable plate 4310 presses the material into the main bundling chamber 46. When the filler connecting rod 4304 drives the scissor mechanism to pull the movable plate 4310 upward, the side baffles 4306 follow the movable plate 4310 upward along the guide posts 4307, opening the filler bin 4301 and allowing the lateral feed mechanism 42 to feed the material into the filler bin 4301. The scissor mechanism replaces the small rotational stroke of the filler crank 4303 with the large vertical movement of the movable plate 4310, significantly increasing the compression space and improving the compaction of the material.

[0101] The main bale chamber 46 is arranged at the rear middle lower part of the grain harvester and baler, and includes a main bale chamber top plate 4601, a main bale chamber bottom plate 4602, a main bale chamber front plate 4603, a main bale chamber rear plate 4604 and a main bale chamber side plate 4605.

[0102] like Figure 37-Figure 39 As shown, the transverse compression device 44 is a crank-type horizontal rotary transverse compression device, located on the left side of the main bundling chamber 46. It includes a transverse compression actuator assembly and a guide assembly. The transverse compression actuator assembly includes a material blocking slide 4404, a main compression crank 4401, a main compression connecting rod 4402, a plunger cutter 4405, and a grass pusher 4409. The guide assembly includes an upper piston guide plate 4410, a lower piston guide plate 4411, a horizontal roller 4406, an upper vertical roller 4407, and a lower vertical roller 4408. One end of the main compression connecting rod 4402 is hinged to the main compression crank 4401, and the other end is hinged to the grass pusher 4409. The lower piston guide plate 4411 is mounted on the main bundling chamber bottom plate 4602, and the upper piston guide plate 4410 is mounted on the main bundling chamber front plate 4603 and the main bundling chamber rear plate 4604. The grass pushing plate 4409 is equipped with a horizontal roller 4406, an upper vertical roller 4407, a lower vertical roller 4408, and a material blocking slide plate 4404.

[0103] The power output shaft 4817 of the bevel gearbox 4403 outputs power perpendicularly to the main compression crank 4401 of the transverse compression actuator and the first-stage chain drive sprocket 4802. The main compression crank 4401 drives the main compression connecting rod 4402, which in turn drives the material blocking slide 4404, plunger cutter 4405, and grass pusher 4409.

[0104] The guide assembly is used to support and guide the transverse compression actuator and related components, ensuring a smooth transverse compression process. The material in the main bale chamber 46 is further compressed by the pusher plate 4409, driven by the crank-connecting rod mechanism formed by the main compression crank 4401 and the main compression connecting rod 4402. The pusher plate 4409 reciprocates under the guidance of the upper piston guide plate 4410 and the lower piston guide plate 4411. The pusher plate 4409 has several protrusions that greatly improve the compactness of the bale compression. The horizontal roller 4406 rolls on the main bale chamber front plate 4603 and the main bale chamber rear plate 4604 to achieve transverse positioning; the upper vertical roller 4407 and the lower vertical roller 4408 roll on the main bale chamber top plate 4601 and the main bale chamber bottom plate 4602, respectively, to achieve longitudinal positioning.

[0105] The plunger cutter 4405 and the material blocking slide 4404 are fixed together by a connecting piece and are located at the same height, and together they cut and block the excess material from the stuffing box 4301. When the main compression link 4402 drives the grass pushing plate 4409 to push the material, the material blocking slide 4404 and the plunger cutter 4405 move with the grass pushing plate 4409 to the bottom of the stuffing box 4301, blocking the material from the stuffing box 4301, and the material will not enter the main bundling chamber 46 at this time; when the main compression link 4402 drives the grass pushing plate 4409 to retreat, the material blocking slide 4404 and the plunger cutter 4405 retreat with the grass pushing plate 4409, opening the main bundling chamber 46, so that the material in the stuffing box 4301 can enter the main bundling chamber 46.

[0106] like Figure 13-14As shown, the horizontal baling device 4 also includes a timing protection mechanism 47; the timing protection mechanism 47 is arranged in the rear middle part of the grain harvester and baler, and the timing protection mechanism 47 includes a rope feeding mechanism and a protection mechanism; the rope feeding mechanism includes a rope needle driving crank 4501, a rope needle frame connecting rod 4502, a rope needle frame connecting plate 4503, a rope needle frame 4504 and a rope needle 4505; one end of the rope needle frame connecting rod 4502 is hinged to the rope needle driving crank 4501, and the other end is hinged to the rope needle frame connecting plate 4503, the rope needle frame connecting plate 4503 is fixed to the rope needle frame 4504, and the rope needle 4505 is installed on the rope needle frame 4504; The protection mechanism includes a short crank 4701, a long connecting rod 4702, a slide rod 4703, a short connecting rod 4704, a triangular pendulum 4705, a second short connecting rod 4706, a stop pin 4707, a guide sleeve 4708, a sleeve 4709, a mounting plate 4710, a first safety bolt 4711 and a second safety bolt 4712; one end of the long connecting rod 4702 is hinged to the short crank 4701, and the other end is hinged to one end of the slide rod 4703; one end of the short connecting rod 4704 is hinged to the other end of the slide rod 4703, and the other end of the short connecting rod 4704 is hinged to a hinge point of the triangular pendulum 4705; the fixed hinge point of the triangular pendulum 4705 It is arranged on the mounting plate 4710 fixed on the rear plate 4604 of the main bundling chamber, one end of the secondary short link 4706 is hinged to the other hinge point of the triangular rocker 4705, and the other end is hinged to the stop pin 4707; the guide sleeve 4708 is fixed to the second reversing bracket 4824, and the slide bar 4703 can slide in the guide sleeve 4708; the mounting plate 4710 is fixed to the rear plate 4604 of the main bundling chamber, and a sleeve 4709 is installed on the mounting plate 4710, and the stop pin 4707 can slide in the sleeve 4709; the first safety bolt 4711 is installed on the rope needle driving crank 4501, and the second safety bolt 4712 is installed on the fly The timing protection mechanism 47 is driven by the short crank 4701 and is linked to the rope feeding mechanism. When the first safety bolt 4711 of the rope feeding mechanism is fatigued and breaks, the movement timing of the rope needle frame 4504 is disordered, and the stop pin 4707 extending from the sleeve 4709 will block the main compression crank 4401 of the crank horizontally rotating transverse compression device 44, so that the second safety bolt 4712 on the flywheel 4801 that inputs power is cut off, and the total power of the baling device is cut off, thereby protecting the rope needle 4505 from being damaged by the grass pieces compressed by the piston, avoiding the rope needle 4505 from further damaging the knotter parts, and effectively improving the service life of the knotting and bundling component 45.

[0107] The guide sleeve 4708 is used to guide and constrain the displacement of the slide bar 4703, ensuring the accuracy and stability of its trajectory and position. The short crank 4701 drives the slide bar 4703 to slide along the guide sleeve 4708 via the long connecting rod 4702. The slide bar 4703 drives the triangular swing arm 4705 to swing about a fixed hinge point on the mounting plate 4710 via the short connecting rod 4704. The triangular swing arm 4705 drives the stop pin 4707 to slide along the sleeve 4709 via the second short connecting rod 4706. When the needle rack 4504 is in its lowest position, the stop pin 4707 retracts into the sleeve 4709; when the needle rack 4504 is in its highest position, the stop pin 4707 extends out of the sleeve 4709.

[0108] The timing protection mechanism 47 is driven by a short crank 4701 and is linked to the rope feed mechanism. When the first safety bolt 4711 of the rope feed mechanism fatigues and breaks, the movement timing of the rope needle frame 4504 is disrupted. The stop pin 4707 extending from the sleeve 4709 blocks the main compression crank 4401 of the crank-rotating transverse compression device 44, causing the second safety bolt 4712 on the flywheel 4801, which inputs power, to shear, cutting off the total power to the baling device. This protects the rope needle 4505 from being damaged by the blades compressed by the piston, preventing the rope needle 4505 from further damaging the knotter parts, effectively extending the service life of the knotting and bundling components.

[0109] like Figure 11-Figure 39 As shown, the baling transmission system 48 is also included; the baling transmission system 48 includes a flywheel 4801, a first-stage chain drive driving sprocket 4802; a first-stage chain drive driven sprocket 4803; an intermediate double-row transition sprocket 4804; a transition sprocket 4805; a vertical filler power input sprocket 4806; a knotting power input sprocket 4807; a knotting drive sprocket 4808; a first driving bevel gear 4809; a first driven bevel gear 4810; a feeder gear driven gear 4811; a feeder gear driving gear 4812; a feeder gear driving sprocket 4813; and a feeder gear driven sprocket 4814. ; Belt roller power input sprocket 4815; Power input shaft 4816; Power output shaft 4817; Transverse feed drive sprocket 4818; Transverse feed double-row sprocket 4819; Second driving bevel gear 4820; Second driven bevel gear 4821; Material receiving transition sprocket 4822; First reversing bracket 4823; Second reversing bracket 4824; First driven bevel gear shaft 4825; Second driving bevel gear shaft 4826; Second driven bevel gear shaft 4827; Belt roller power input shaft 4828; Belt roller power output shaft 4829; Material feed gear sprocket shaft 4830.

[0110] The baling drive system 48 generates power through a diesel engine, which drives a flywheel 4801 through a multi-stage transmission. A small bevel gear at the end of a power input shaft 4816 attached to the flywheel 4801 meshes with a large bevel gear on a power output shaft 4817, transmitting power to the power output shaft 4817 of a bevel gearbox 4403 attached to the main baling chamber floor 4602. Power is vertically transmitted from both ends of the power output shaft 4817 to the main compression crank 4401 of the transverse compression actuator and the first-stage chain drive sprocket 4802. The first-stage chain drive driving sprocket 4802 distributes the power to the first-stage chain drive driven sprocket 4803 and the intermediate double-row transition sprocket 4804 through the wrapping chain transmission; the first driving bevel gear 4809 coaxially mounted with the first-stage chain drive driven sprocket 4803 meshes with the first driven bevel gear 4810 on the first driven bevel gear shaft 4825, and switches the power to the first driven bevel gear shaft 4825 on the first reversing bracket 4823 fixed in front of the main bundling chamber 46. 825; the transition sprocket 4805 fixed to the other end of the first driven bevel gear shaft 4825 transmits power to the belt roller power input sprocket 4815 through a chain; the transmission ratio of the first-stage chain drive driving sprocket 4802 and the belt roller power input sprocket 4815 is 1:2, and the direction of the first-stage chain drive driving sprocket 4802 is counterclockwise when viewed from the bottom surface of the main bundling chamber 46, and the direction of the belt roller power input sprocket 4815 is clockwise when viewed from the end surface of the flywheel 4801.

[0111] The belt roller power input shaft 4828 drives the roller blanking conveyor belt 4103 to rotate. The feeder gear driving sprocket 4813, which is coaxially mounted with the belt roller power input sprocket 4815, drives the feeder gear driven sprocket 4814, which is fixed to the feeder gear sprocket shaft 4830, to rotate via a chain. The feeder gear driving gear 4812, which is coaxially mounted with the feeder gear driven sprocket 4814, meshes with the feeder gear driven gear 4811, driving the spiral feeder gear 4105 to rotate.

[0112] The intermediate double-row transition sprocket 4804 and the transition sprocket 4805 redirect the power to the second active bevel gear shaft 4826 fixed on the second reversing bracket 4824 of the main bundling chamber rear plate 4604 of the main bundling chamber 46 through a chain; the second active bevel gear 4820 fixed on the second active bevel gear shaft 4826 is meshed with the second driven bevel gear 4821 on the second driven bevel gear shaft 4827; the knotting drive sprocket 4808 coaxially mounted with the second driven bevel gear 4821 drives the knotting power input sprocket 4807 through a chain, so that the knotting and bundling component 45 moves; the transverse The feeding drive sprocket 4818 drives the transverse feeding double-row sprocket 4819 through a chain to operate the transverse feeding mechanism 42; the transverse feeding double-row sprocket 4819 then drives the vertical filling power input sprocket 4806 through a chain to move the vertical filling device 43; the transmission ratio of the first-stage chain drive active sprocket 4802 and the knotting power input sprocket 4807, the transverse feeding double-row sprocket 4819, and the vertical filling power input sprocket 4806 is 1:1:1:1. When viewed from the rear of the main bundling chamber 46, the knotting power input sprocket 4807, the transverse feeding double-row sprocket 4819, and the vertical filling power input sprocket 4806 all rotate counterclockwise.

[0113] In one embodiment of the present invention, the transmission ratios of the first-stage chain drive drive sprocket 4802 and the knotting power input sprocket 4807, the double-row lateral feed sprocket 4819, the vertical filling power input sprocket 4806, and the belt roller power input sprocket 4815 are 1:1:1:1:2. When viewed from the bottom of the bundling chamber, the first-stage chain drive drive sprocket 4802 rotates counterclockwise. When viewed from the rear of the bundling chamber, the knotting power input sprocket 4807, the double-row lateral feed sprocket 4819, and the vertical filling power input sprocket 4806 all rotate counterclockwise. When viewed from the flywheel end face, the belt roller power input sprocket 4815 rotates clockwise. Power is transmitted and reversed through chain drive and bevel gear transmission, completing the longitudinal splicing, lateral feeding, vertical filling, and knotting and bundling operations during the bundling process. The use of a wrapping chain drive ensures transmission accuracy and reliability. This bundling transmission system features a compact transmission path, an attractive layout, and easy installation.

[0114] The installation position of the grain harvester and baler is as follows: when the main compression crank 4401 and the main compression connecting rod 4402 of the crank horizontal rotating transverse compression device 44 overlap and are collinear, the axis of the gear box 4216 of the transverse feeding mechanism 42 is horizontally facing left, and the filling crank 4303 and the filling connecting rod 4304 of the vertical filling device 43 are straightened and collinear.

[0115] like Figures 40-41As shown, the extended bundling chamber 49 includes a rectangular body, a connecting assembly and a locking assembly; the rectangular body is open at both ends, and one side of the rectangular body is connected to the main bundling chamber 46 through the connecting assembly. The rectangular body can be flipped 180 degrees around the connecting assembly and locked by the locking assembly, so that the outlet of the main bundling chamber 46 is connected to the rectangular body, and the material is discharged after being squeezed by the extended bundling chamber 49.

[0116] In one embodiment of the present invention, the extended baling chamber 49 is a tiltable extended baling chamber, located in the center right rear portion of the grain harvester-baler. The connecting assembly includes an upper tilting connector 4905, a lower tilting connector 4906, and a rotating shaft 4907. The locking assembly includes a first locking mechanism 4901, a second locking mechanism 4902, a first latching seat 4903, and a second latching seat 4904.

[0117] The upper flip connector 4905 is fixed to the extended bundling chamber 49, while the lower flip connector 4906 is fixed to the main bundling chamber front panel 4603 and the main bundling chamber rear panel 4604, respectively. The upper flip connector 4905 is hingedly connected to the lower flip connector 4906 via a rotating shaft 4907. A first locking mechanism 4901 and a second locking mechanism 4902 are mounted on the extended bundling chamber 49; a first latching seat 4903 and a second latching seat 4904 are mounted on the main bundling chamber rear panel 4604 and the main bundling chamber front panel 4603. The first locking mechanism 4901 is mounted in conjunction with the first latching seat 4903, while the second locking mechanism 4902 is mounted in conjunction with the second latching seat 4904. A main bundling chamber upper crossbeam 4606 is mounted on the main bundling chamber 46.

[0118] The extended bundling chamber 49 is manually flipped. When bundling is to be performed, the second locking mechanism 4902 is released to disengage the second latch seat 4904, and the extended bundling chamber 49 is flipped downward. When the end surface of the extended bundling chamber 49 near the rotating shaft is aligned with the right end surface of the main bundling chamber 46, the first locking mechanism 4901 is fastened to the first latch seat 4903, thereby extending the main bundling chamber 46. When the bundling operation is completed, the first locking mechanism 4901 is released to disengage the first latch seat 4903, and the extended bundling chamber 49 is flipped upward. When the extended bundling chamber 49 rests on the upper crossbeam 4606 of the main bundling chamber 46, the second locking mechanism 4902 is fastened to the second latch seat 4904, thereby securing the flip-type extended bundling chamber 49.

[0119] The extended bale chamber 49 is a rectangular welded component with opposing extension plates on the upper and lower sides. The extensions fill the gap between the upper and lower sides of the main bale chamber 46, improving bale transport stability and bale compaction. The locking assembly, a universal snap-on locking mechanism, secures the extended bale chamber 49, ensuring a tight and stable connection between the extended bale chamber 49 and the main bale chamber 46, enhancing the flexibility and adaptability of the grain harvester and baler. The extended bale chamber 49 can be rotated 180 degrees about a pivot 4907. With its simple structure and easy operation, the extended bale chamber 49 solves the problem of loose bales caused by insufficient bale compression due to a too short main bale chamber, while also ensuring the grain harvester and baler maintains a safe width.

[0120] like Figure 18-19 As shown, the working route of the present invention is as follows: after the crops are cut by the harvesting platform 8, they are fed from the side through the conveying device 7 to the longitudinal axial flow threshing component 3, the grains fall to the cleaning component 5 and are then sent to the grain box 2, and the materials are discharged from the tail of the longitudinal axial flow threshing component 3 to the longitudinal material receiving device 41. The roller-type drop conveyor belt 4103 and the spiral material-picking teeth 4105 work together to allow the materials to enter the material box 4201 where the transverse feeding mechanism 42 is located. The claw group pushes the materials to the stuffing box 4301, and under the action of the crank rocker and the scissor mechanism, the materials are pressed into the main baling chamber 46. The transverse compression device 44 further compresses the materials, and the knotting and bundling component 45 uses a rope to bundle the materials into bales, which are discharged from the flip-type extended baling chamber 49 and dropped onto the harvested wheat rows. The present invention is suitable for wheat harvesting and baling in the wheat-cotton intercropping mode, and can also be used for harvesting and baling other grains, and has a wide range of applications.
