[0021] In this embodiment, the ear-stem separation mechanism 5 is an inherent structure of the grain harvester, which is a prior art, such as an ear-stem separation mechanism in an ear-stem and harvesting device disclosed in CN210928650U.
[0022] The beneficial effects of the above technical solution are: After grains (such as corn) are harvested by the ear-stalk separation mechanism 5, they fall from the ear-stalk separation mechanism 5 onto the first horizontal transport component 1, and are then transported to the vertical transport component 2 through the first horizontal transport component 1.

The height of the left side of the slope 19 is greater than the height on the right side, and a gate 20 is slidably connected to the right side of the box 17 in the up and down directions. A group of sliding grooves 21 in the up and down directions are respectively provided on the front and rear end surfaces of the right side of the box 17, and the front and rear end surfaces of the gate 20 are respectively fixedly connected to a control rod 22 horizontally arranged in the front and rear directions, and the control rod 22 extends from the sliding groove 21.
[0027] Preferably, the hydraulic lifting assembly 3 includes a hydraulic box 23, which is fixedly connected to the upper surface of the harvester body 6. A plurality of output rods 24 that run synchronously in the up and down directions are evenly arranged on the upper surface of the hydraulic box 23 at intervals on the left and right.
[0028] Preferably, the second horizontal transport component 4 includes a base plate 25, which is fixedly connected to the upper end of the output rod 24, and a transmission box 26 is arranged at the right end of the upper surface of the base plate 25. A conveyor belt 27 along the front-to-back direction is arranged in the transmission box 26, and two second mounting plates 28 arranged along the left-to-right direction are fixedly connected above the transmission box 26, and a plurality of support plates 29 are fixedly connected between the lower surface of the second mounting plates 28 and the upper surface of the base plate 25. A conveyor belt 30 along the left-to-right direction is fixedly installed between the two second mounting plates 28, and a feed hopper 31 is fixedly connected to the left end of the second mounting plate 28. The discharge port of the feed hopper 31 is located above the conveyor belt 30, and two groups of trigger components are symmetrically arranged on the front and rear sides of the feed hopper 31, and the trigger components are used to open the gate 20.
[0029] Preferably, the trigger assembly includes a mounting frame 32, which is fixedly connected to the second mounting plate 28, and the upper end of the mounting frame 32 is fixedly connected to a third mounting plate 33 arranged along the left-right direction, and the right end of the third mounting plate 33 close to the box body 17 is fixedly connected to a limiting block 34, and the upper surface of the limiting block 34 is fixedly connected to a control groove 35, and the third mounting plate 33 is rotatably connected to a rotating plate 36 on the side close to the box body 17, and the inner bottom surface of the control groove 35 is fixedly connected to a spring 37 arranged in a vertical direction, and the upper end of the spring 37 is fixedly connected to the lower surface of the right side of the rotating plate 36.
[0030] In this embodiment, a friction plate is provided on the inner wall of the sliding groove 21 to limit the falling speed of the gate 20 .
[0031] The beneficial effects of the above technical solution are: By setting the first mounting plate 8, an installation position is provided for the installation of the conveyor belt 9. At the same time, the first mounting plate 8 acts as a guardrail to prevent grain from leaking from the side of the conveyor belt 9, thereby reducing the amount of grain loss during grain harvesting.
[0032] By setting the guide trough 10, the grains are guided when they leave the conveyor belt 9, ensuring that the grains fall into the box 17, avoiding the grains from falling out of the box 17 during the transfer process, and further reducing the loss of grains.
[0033] When the left end of the box 17 contacts the inclined surface 12, under the squeezing action of the trigger plate 11, the hanging ring 16 rotates counterclockwise on the central axis 14, so that the box 17 is in a state where the left side is low and the right side is high, which facilitates the grain to fall into the box 17. When the transfer basket assembly leaves the position near the trigger plate 11, it will return to a horizontal state under the action of gravity, preventing the grain from falling from the box 17 during transportation, thereby further reducing the loss of grain.
[0034] When the transfer basket assembly reaches the position for interfacing with the second horizontal transport assembly 4, as the box body 17 descends, the lower surface of the control rod 22 contacts the upper surface of the left side of the rotating plate 36. As the box body 17 further descends, the gate 20 moves upward under the push of the rotating plate 36 (at this time, the rotating plate 36 is in a horizontal state under the action of the spring 37), so that the grain is poured out from the right side of the box body 17 and falls into the feed funnel 31. When the gate 20 moves to the highest point, as the box body 17 further descends, under the action of the downward force exerted by the control rod 22 on the left side of the rotating plate 36, the rotating plate 36 rotates counterclockwise, so that the control rod 22 passes through the rotating plate 36 area, and then the gate 20 returns to the initial position under the action of gravity, and the rotating plate 36 returns to a horizontal state under the action of the spring 37. Finally, the grain is transmitted alternately by the conveyor belt three 30 and the conveyor belt two 27, thereby realizing the unloading of the grain.
[0035] By setting the trigger component, the gate 20 is automatically opened when it approaches the second horizontal transport component 4, and is automatically reset when the transfer basket component passes through the second horizontal transport component 4. No additional operation is required, which reduces the complexity of the operation. The height of the trigger device changes with the height of the second horizontal transport component 4, thereby achieving the adjustment of the connection height between the vertical transport component 2 and the second horizontal transport component 4 and the height for unloading the grain by adjusting the height of the second horizontal transport component 4, thereby reducing the height difference during grain transfer and improving the integrity of the grain.
[0036] Example 3 On the basis of Example 2, a discharge baffle 40 rotating in the vertical direction is provided at the outlet of the transfer box 26, and the discharge angle of the discharge baffle 40 is controlled and adjusted based on the angle control module, and the angle control module includes: A power assembly, used to control the unloading baffle 40 to rotate in the vertical direction; A speed sensor for obtaining the traveling speed of the grain harvester; Humidity sensor, used to obtain relative humidity of air; Vibration sensors for obtaining vibration data from grain harvesters; An angle calculation unit, used to calculate a target unloading angle of the unloading baffle 40; ;in, is the target unloading angle of the unloading baffle 40; is the inverse tangent function; is the speed margin factor; is the harvesting width of the ear-stem separation mechanism 5; V is the travel speed of the grain harvester; M is the average grain yield per grain plant; U is the planting density of the grain plants; is the width of the conveyor belt 27; H is the maximum allowable material stacking height on the conveyor belt 27; Refers to the bulk density of grains; is the actual roughness of the transmission surface of the conveyor belt 27; is the preset standard transmission surface roughness; X is the grain shape factor; is the actual relative humidity of the air; is the preset reference air relative humidity; is the conversion factor of relative humidity of air; Z is the vibration influence factor; g is the acceleration of gravity; The angle control unit is used to adjust the actual unloading angle of the unloading baffle 40 to the target unloading angle of the unloading baffle 40 .
[0037] In this embodiment, the discharge angle is the angle between the discharge baffle 40 and the vertical plane.
[0038] In this embodiment, the speed margin coefficient is used to avoid material blockage on the conveyor belt, and the value adopted is greater than the coefficient adopted for the correction and increase of the conveyor belt speed.
[0039] In this embodiment, the harvesting width of the ear-stem separation mechanism 5 refers to the width that the ear-stem separation mechanism 5 can harvest during the operation of the grain harvester.
[0040] In this embodiment, the planting density of cereal plants refers to the number of cereal plants planted per unit area of land.
[0041] In this embodiment, the grain shape factor refers to an influencing factor determined according to the external shape of the grain. In order to improve the convenience of calculation, the grain shape factor corresponds to the grain type. The grain shape factor is obtained by referring to the grain shape factor-grain type correspondence table. The grain shape factor of each grain in the grain shape factor-grain type correspondence table is obtained by experimental measurement and analysis, and the value of the grain shape factor is greater than 1.
[0042] In this embodiment, the reference air relative humidity refers to the relative humidity of the air at which the difficulty of transporting grains is just not affected.
[0043] In this embodiment, the conversion factor of the relative humidity of the air is a conversion coefficient for converting the relative humidity of the air into the degree of influence on the difficulty of grain transportation.
[0044] In this embodiment, the vibration influence factor is an influence factor that reflects the degree of influence of equipment vibration on the difficulty of grain transportation. The vibration influence factor is obtained by looking up the maximum amplitude-vibration influence factor correspondence table according to the range of the maximum amplitude of the equipment. The vibration influence factor in the maximum amplitude-vibration influence factor correspondence table is obtained by experimental measurement and analysis.
[0045] The beneficial effects of the above technical solution are: By adjusting the unloading angle of the unloading baffle 40 in real time, it is ensured that the grain can flow out of the transfer box 26 smoothly, reducing the probability of blockage and the failure rate of the grain harvester; at the same time, the unloading trajectory of the grain is corrected to ensure that the grain falls smoothly into the transport vehicle, reducing the loss and waste of grain during the unloading process. Real-time adjustment of the unloading angle can adapt to different operating conditions and different grain characteristics, ensuring efficient grain unloading under different operating conditions and different grain characteristics, ensuring the smooth unloading of different types of materials, and avoiding material damage or waste due to inappropriate angle setting.

[0047] The beneficial effects of the above technical solution are: The height of the second horizontal transport component 4 is adjusted by the hydraulic lifting component 3, so that the connection height between the vertical transport component 2 and the second horizontal transport component 4 and the height for unloading the grains are changed, so that the unloading height of the grains matches the specifications of the transport vehicle, thereby reducing the falling height of the grains, reducing the damage to the grains during the falling process of the grains, and improving the integrity of the grains when harvesting.
