In some embodiments, the traveling unit 500 includes a front driving assembly and a rear driving assembly, which are symmetrically arranged in the length direction of the frame 100 with the storage unit 400 as a center of symmetry.

As shown in fig. 12, the front driving assembly is a front axle driving assembly, the rear driving assembly is a rear axle driving assembly, and the front driving assembly and the rear driving assembly are symmetrically arranged in the front-rear direction with the center line of the storage tank 1 in the front-rear direction as a symmetry axis. The front and rear driving components are symmetrically arranged by the storage box1, so that the running stability of the whole machine can be ensured.

In some embodiments, the front and rear drive assemblies each include a suspension assembly 3, a track adjustment assembly 4, and a steering assembly 5, the suspension assembly 3 being located between the track adjustment assembly 4 and the frame 100, the steering assembly 5 being connected to the track adjustment assembly 4.

As shown in fig. 12 and 13, the suspension assemblies 3 have two, two suspension assemblies 3 are respectively located on the front side and the rear side of the frame 100, in other words, two suspension assemblies 3 are respectively fitted to the front drive assembly and the rear drive assembly, and the suspension assemblies 3 located on the front side and the suspension assemblies 3 located on the rear side are arranged in mirror image with the center line in the front-rear direction of the frame 100 as mirror image center. The front and rear suspension assemblies 3 are distributed in a mirror image mode, so that the front and rear shock absorption uniformity of the frame 100 can be improved, the running stability of the whole machine is improved, and the harvesting efficiency and quality are guaranteed.

As shown in fig. 15, for example, the suspension assembly 3 includes a link member 31, a damper airbag 32, a damper 33, and a check chain 34, wherein the link member 31 is disposed in a lateral direction in a length direction of the frame 100, the damper airbag 32, the damper 33, and the check chain 34 are disposed in a longitudinal direction in a height direction of the frame 100, that is, one end of the link member 31 is pivoted to the telescopic sleeve 41 in a horizontal direction, the other end of the link member 31 is pivoted to the frame 100, and the damper airbag 32, the damper 33, and the check chain 34 are located between the telescopic sleeve 41 and the frame 100 in a vertical direction.

The link members 31 include four links which are arranged at intervals in the up-down direction in a pair by pair and two links in the same group are arranged at an angle, for example, in the case of the suspension assembly 3 on the rear side, two links on the upper side are arranged obliquely from the rear to the front, the interval distance between the two links is gradually increased from the rear to the front to be splayed, the interval distance between the two links on the lower side is gradually decreased from the rear to the front, and the links on the upper-lower direction are arranged in an X-shape, so that a four-link mechanism is formed, and the structural stability between the link members 31 and the frame 100 and the track adjusting assembly 4 can be improved, and the uniformity of shock absorption can also be ensured.

Since the front suspension unit 3 and the rear suspension unit 3 are mirror images, the extending direction of the link in the front suspension unit 3 is mirror images of the extending direction of the rear suspension unit 3.

As shown in fig. 17 and 18, the suspension assembly 3 further includes a stopper chain 34, wherein when the wheel falls down in the moment when the wheel encounters a depressed road, the damper air bag 32 and the damper 33 are both stretched, the stopper chain 34 is changed from a "relaxed state" to a "strained state", and when the wheel is lifted up in the moment when the wheel encounters a raised road, the damper air bag 32 and the damper 33 are both compressed, and the stopper chain 34 is changed from a "strained state" to a "relaxed state". When the wheels fall in the moment when the wheels meet the hollow pavement, the limiting chains 34 can control the falling distance of the wheels, so that the damping air bags 32 and the dampers 33 are stretched in the safety travel of the wheels, namely, the limiting chains 34 can play a role in protecting the damping air bags 32 and the dampers 33. Conversely, when the wheel is lifted at the moment when the wheel encounters a raised road surface, the stopper chain 34 does not affect the compression of the shock absorbing air bag 32 and the shock absorber 33. The damping effect of the frame 100 and the devices connected thereto is achieved under the combined action of the damping air bags 32, the dampers 33 and the spacing chains 34.

Various forces and moments acting on wheels 424 from the ground are transmitted to frame 100 by suspension assembly 3, and vibrations of frame 100 and the vehicle body are rapidly damped, ensuring normal running of the high-clearance running chassis. The shock absorbers 33 adopt a dual-acting cylinder type shock absorber, so that the shock absorbers 33 of the left and right wheels can work independently, the damping force is automatically adjusted according to the real-time jumping state (compression or extension) of the corresponding wheels 424, when the vehicle runs on an asymmetric road surface (such as single-side jolt), the left and right shock absorbers 33 are not interfered with each other, the shock of the corresponding wheels 424 can be independently and accurately absorbed, and when the vehicle body moves integrally (such as steering roll and pitching), the shock absorbers 33 on the two sides work cooperatively through the damping characteristics, the change of the vehicle body posture is restrained together, and the running stability of the chassis is maintained.

As shown in fig. 17, for example, when the front of the wheel encounters a depressed road and the rear of the wheel encounters a raised road, the shock absorbing bladder 32 and the shock absorber 33 compress, the wheel is lifted, and the shock absorbing bladder 32 and the shock absorber 33 stretch when the front wheel encounters a depressed road, the wheel falls, and the four links in the front link member rotate downward about the hinge point with the frame 100, and the four links in the rear link member rotate upward about the hinge point with the frame 100, thereby achieving a shock absorbing effect and maintaining the frame in a horizontal state in the front-rear direction as much as possible.

As shown in fig. 18, two ends of the link member 31 in the suspension assembly 3 are pivotally connected to the frame 100 and the telescopic sleeve 41, respectively, and under the action of the four-bar mechanism formed by the link member 31, the suspension assembly 3 can rotate around the link pivot point in a plane defined by the telescopic sleeve 41 and the left and right support shafts 421, and at this time, the shock-absorbing air bag 32 and the shock absorber 33 on the side with high wheels are compressed, and the shock-absorbing air bag 32 and the shock absorber 33 on the side with low wheels are stretched. For example, when the left and right wheels of the harvester travel on different road conditions and the left and right wheels are high and low, the operating states of the shock absorbing air bags 32 and the shock absorbers 33 in the suspension assembly 3 can be realized through the link members 31, and the vehicle frame can be maintained in a horizontal state in the left-right direction.

In some embodiments, track adjustment assembly 4 includes a telescoping sleeve 41 and first and second wheel components 42, 43, telescoping sleeve 41 extending along a width direction of frame 100, a fixed end of telescoping sleeve 41 being coupled to frame 100 by shock-absorbing bladder 32, shock absorber 33, and check chain 34, telescoping ends of telescoping sleeve 41 being coupled to first and second wheel components 42, 43, respectively, and first and second wheel components 42, 43 being movable toward and away from each other in the width direction of frame 100.

As shown in fig. 15, the number of the third hydraulic cylinders 44 is two, the telescopic ends of the telescopic sleeve 41 are also two, the two telescopic ends are symmetrically arranged in the left-right direction, the two third hydraulic cylinders 44 are respectively connected with the two telescopic ends, and the first wheel component 42 and the second wheel component 43 can be driven to be close to or far from each other by arranging the telescopic sleeve 41 and the third hydraulic cylinders 44, so that the effect of adjusting the wheel distance of the wheels 424 is achieved, and harvesting operations of different sowing line distances are satisfied.

In some embodiments, the first wheel member 42 and the second wheel member 43 each include a support shaft 421, a first support frame 422, a driver 423, and a wheel 424, the upper end of the support shaft 421 is connected to the telescopic sleeve 41, the lower end of the support shaft 421 is connected to the first support frame 422, the driver 423 is mounted on the first support frame 422, and the output shaft of the driver 423 is connected to the wheel 424.

It should be noted that, the track adjusting assembly 4 at the front side and the track adjusting assembly 4 at the rear side have the same structure, so that the four wheels 424 capable of rotating independently are utilized to realize the four-wheel rotation of the harvester, and the differential rotation of the wheels 424 is realized by setting different rotation speed control methods, so that different control on the travelling path of the harvester is realized, for example, the in-situ steering of the harvester can be realized, the steering radius is reduced, and the harvester is beneficial to operating in the area with a narrow turning radius.

In some embodiments, the first wheel component 42 and the second wheel component 43 in the front drive assembly each employ a caster arrangement, the first wheel component 42 and the second wheel component 43 in the rear drive assembly each employ a caster arrangement, and the caster angle of the first wheel component 42 and the second wheel component 43 in the front drive assembly is greater than the caster angle of the first wheel component 42 and the second wheel component 43 in the rear drive assembly.

So set up, when the road surface is high and low, can produce the frictional force in the dead ahead, prevent that frame 100 from rocking about, in time pull the dead ahead frame 100, effectively improve the straight line stability of going of whole car, because the equipment height of harvester front side is higher, when the harvester produced jolting, the swing range that the frame 100 front side produced is great, therefore the caster angle of the caster pin of first wheel part 42 and second wheel part 43 in the front drive subassembly is greater than the caster angle of the caster pin of first wheel part 42 and second wheel part 43 in the rear drive subassembly, the stability that the whole car was gone is guaranteed to the swing of resistance harvester front side that can be better.

In some embodiments, first and second wheel components 42, 43 in the front drive assembly and first and second wheel components 42, 43 in the rear drive assembly are each in a positive camber arrangement, and first and second wheel components 42, 43 in the front drive assembly and first and second wheel components 42, 43 in the rear drive assembly are each in a kingpin camber arrangement. So set up, after the harvester carries cargo, wheel 424 receives pressure and returns well, increases the area of force of tire, guarantees the grabbing power of whole car, improves the stability that the harvester was gone.

And/or, the first wheel component 42 and the second wheel component 43 in the front drive assembly are in a positive toe-angle arrangement.

It should be noted that, when the whole vehicle runs forward, the wheels 424 are subjected to rolling resistance, and the ground pulls the tires to deform slightly, so that the suspension is damped and pulled backwards, and the wheels 424 at two sides are outwards opened, therefore, the front toe angle is designed in advance to offset the outwards opened angle of the wheels 424 at two sides, and the running safety and stability of the whole vehicle are ensured.

Optionally, a hub reduction gear is connected to the output shaft of the driver 423, and the power output shaft of the hub reduction gear is connected to the wheels, in other words, the power is transmitted to the reduction gear through the driver 423 and then transmitted to the wheels by the reduction gear.

As shown in fig. 19, the embodiment of the invention further provides a silage harvesting method for a seed production corn male parent, which is used for controlling a harvesting device, and the harvesting method comprises the following steps:

And S100, controlling a header assembly 6 in the harvesting unit 600 to harvest crops, and controlling a throwing assembly 7 in the header assembly 6 to throw the harvested crops to the storage unit 400.

For example, the row ratio planting mode of the male parent and the female parent of the crop can be determined according to the field growth condition of the seed corn, and row spacing information of the male parent plant and the female parent plant can be obtained.

The horizontal position and the height of the header assembly are adjusted through the cutting adjusting assembly, so that crops are harvested on the rows in the harvesting process. According to the growth vigor of the male parent row plants, the opening degree of the straw supporting rods of the straw supporting component and the spacing between two layers of straw supporting rods are adjusted, so that the straw supporting component has proper straw supporting space.

It should be noted that, the left and right positions of the header assembly 6 are determined based on sowing row spacing information, and a range radar can be installed on the front side of the header assembly 6, so that the left and right positions of the header assembly 6 are calibrated at the same time by using the range radar, and the header assembly 6 is ensured to be capable of harvesting corn stalks all the time. The harvested corn stalks are conveyed into the storage box 1 for temporary storage, and after the storage box 1 reaches a discharging condition, the materials in the storage box 1 are discharged.

And S200, controlling the throwing component 7 to swing reciprocally according to a preset frequency.

It should be noted that, because the silage corn has a higher water content and the corn fiber is still present, the friction and cohesiveness between the corn stalks are stronger than those of the dried stalks, if the position of the throwing barrel part 71 is unchanged all the time, a conical stacked material is formed, resulting in a reduction in the storage performance of the storage box 1, so that the throwing barrel part 71 needs to be controlled to swing left and right to ensure that the materials are respectively as uniform as possible in the storage box 1.

The frequency of the left-right swing of the drum throwing member 71 can be determined based on information such as the corn plant distance of the land to be harvested and the harvester set harvest amount per unit time.

For example, the corn plant spacing of the plot to be harvested is larger, which means that the corn sowing amount is larger, the harvesting amount is larger in the unit time setting of the harvester, the operation power of the header assembly 6 and the throwing assembly 7 needs to be increased in order to reach the target set value, according to the above information, it can be determined that the feeding amount of the materials in the unit time of the plot to be harvested is larger, and the material entering the storage box 1 is increased due to the increase of the operation power of the header assembly 6 and the throwing assembly 7, so that the material stacking speed is expected to be increased, and the swinging frequency of the throwing barrel assembly 71 needs to be larger.

S300, acquiring the stacking height of the surrounding materials in the storage unit 400.

For example, distance measuring radars are arranged on the periphery of the top of the storage box 1, and the stacking height of the peripheral materials is judged by measuring the distance between the materials in the storage box 1 and the top of the storage box 1.

And S400, controlling the throwing component 7 to convey the materials to the lowest point when the difference of the stacking heights of the materials around reaches a first preset condition.

For example, the first preset condition is that the difference between the average height and the lowest height of the surrounding material is more than 5cm-10cm.

It should be noted that, when the height of a position in the storage box 1 is lower than the average height and exceeds 5cm to 10cm, the risk that the material does not flow to the position is described, namely the risk that the material in the storage box 1 is unevenly distributed to cause single-point too high accumulation is increased, at this time, the throwing component 7 needs to be conveyed to the lowest point, so that the uniformity of material distribution is ensured as much as possible, the time of single operation is prolonged, the time of frequently unloading the material is shortened, and the harvesting efficiency is improved.

The harvesting method may further include S500 of acquiring sowing row spacing information of the seed corn before harvesting, controlling the wheel spacing adjusting assembly 4 in the traveling unit 500 based on the row spacing information to match the wheel spacing of the wheels 424 with the sowing row spacing, and controlling the traveling unit 500 to travel along a predetermined route.

It should be noted that, the sowing line distance of the seed corn can be measured by a range radar installed in front of the harvester, for example, the range radar capable of moving left and right is installed on the left side and the right side, a detection beam is generated in front of the range radar, if the detection beam is folded by corn straw, a reflection beam is formed, after the range radar receives the reflection beam, the position of the range radar in the left and right direction is located near the corn straw, and the spacing distance of the range radar on the left and right sides in the left and right direction is measured.

Or before harvesting, the sowing row spacing is manually measured, and sowing row spacing information is input into a control system to adjust the wheel spacing of the wheels 424.
