[0038] In addition, in the embodiments, the seed melon combine harvester may also include a fruit box oil cylinder 9, which, when the fruit box 26 is full of seeds, extends the fruit box oil cylinder 9 to pour the seeds into the transfer vehicle.

[0039] According to the seed melon combine harvester provided in the embodiments of this application, the seed melon combine harvester may further include a transfer case, a drum, a drum transmission case, and a drum motor. In the embodiments, the transfer case may be connected to the engine for transmission, and the transfer case has a first interface. As an example, the drum motor, the drum transmission case, and the drum are sequentially connected for transmission, and the drum motor is connected to the first interface, so that the drum motor drives the drum transmission case, and the drum transmission case drives the drum.

[0040] In this embodiment, specifically, the first interface 1 of the transfer box is connected to the roller motor, which drives the roller transmission box 27 to drive the roller 29, separating the seeds from the melon and gourd through the concave plate and dropping them into the seed bottom shell 32, while the melon peel is discharged from the tail end of the roller.

The third interface may be connected in series with the slurry drum hydraulic motor to drive the slurry drum hydraulic motor.

[0044] Specifically, according to the seed melon combine harvester provided in the embodiments of this application, the third interface 3 of the transfer box can be connected in series with the hydraulic motor of the slurry drum, so that the melon pulp thrown out of the seeds by the left slurry drum 23 and the right slurry drum 24 is discharged through the small hole of the slurry drum.

[0047] According to the seed melon combine harvester provided in the embodiments of this application, a fourth path can be generated by the second double pump. The seed melon combine harvester may also include a melon divider, and the fourth path is used to drive the melon divider.

[0048] In this embodiment, specifically, the other path of the second double pump, namely the fourth path mentioned above, uses a hydraulic motor to drive the front vine-beating wheel 11 to separate the melons from the melon vines. The hydraulic motor drives the left melon separator 12 and the right melon separator 12 to gather the scattered melons to the middle of the picking roller, preventing the picking roller and tires from crushing the melons and making them unharvestable. The lower vine-removing motor 13 uses a belt drive to separate the melon vines that were not beaten down by the front vine-beating wheel.

[0049] According to the seed melon combine harvester provided in the embodiments of this application, the engine may further include an outer interface, and the seed melon combine harvester may further include a triple pump, which may be directly connected to the outer interface. In the embodiments, a seventh path is branched off from the triple pump, and the seed melon combine harvester may further include a feeding auger, the seventh path being used to drive the feeding auger.

[0050] In this embodiment, specifically, the outer interface 30 of the engine can be directly connected to the triple pump. The first path, i.e. the seventh path, is connected to the feeding auger 15 by the hydraulic motor, and the first vine remover 16, the second vine remover 17 and the reverse vine remover 18 are connected by chain drive on the opposite side, so that the melons in the picking drum can be smoothly transferred to the seed melon elevator 19.

[0051] According to the seed melon combine harvester provided in the embodiments of this application, an eighth path is branched out by a triple pump. The seed melon combine harvester may also include an inner auger of the seed melon elevator, and the eighth path can be used to drive the inner auger of the seed melon elevator.

[0052] In one embodiment, the seed melon combine harvester may further include a melon crushing chamber, a hydraulically driven melon-cutting blade shaft, and a hydraulically driven melon-pressing roller. The inner auger of the seed melon elevator is used to convey the melons to the melon crushing chamber. The melon-cutting blade shaft rotates to cut the melons, and the melon-pressing roller rotates to crush the cut melons.

[0053] In this embodiment, specifically, the second path, namely the eighth path, is driven by a hydraulic motor to transport the melon from the bottom to the melon crushing chamber 31 via an inner auger. In the crushing chamber, the hydraulic motor drives the melon cutting blade shaft 20 to cut the melon, while the hydraulic motor drives the melon pressing roller 21 to rotate and crush the cut melon, exposing the seeds.

[0054] According to the seed melon combine harvester provided in the embodiments of this application, a ninth path can be generated by a triple pump. The seed melon combine harvester may also include a seed conveying auger, and the ninth path is used to drive the seed conveying auger.

[0055] In this embodiment, specifically, the third path, i.e. the ninth path, is driven by a hydraulic motor to the left and right grain conveying augers 22 to transfer the grains separated from the concave plate to the left and right slurry drums 23 and 24. The hydraulic motor drives the horizontal grain conveyor 28 to transport the grains in the slurry drums to the bottom of the vertical grain elevator 25. The horizontal grain conveyor 28 and the vertical grain elevator 25 are driven by a sprocket to transfer the grains from the vertical grain elevator 25 to the fruit box 26.

[0056] Based on the seed melon combine harvester described above, the working process of the seed melon combine harvester will be described below.

[0057] In this embodiment, when the seed melon harvester is harvesting gourds and beating melons, it lowers the cutting platform cylinder 8 so that the picking roller 29 is on the same horizontal plane as the ground. When the gourds and beating melons pass through the front vine-breaking wheel 11, the front vine-removing rubber strip breaks the melon vines. After passing through the melon separator 12, the scattered melons are gathered in the middle of the picking roller 29 to prevent the picking roller 29 and the tires from crushing the melons and making them unharvestable.

[0058] Then, the melons are secured by the picking teeth inside the picking roller 29. The melon vines that were not knocked down by the front vine-removing wheel 11 are separated by the lower vine-removing 14. They then pass through the comb teeth, the sliding plate, and roll into the cutting platform. Inside the cutting platform, the gourds and melons are sent to the bottom of the seed melon elevator 19 by the action of the first vine-removing 16, the second vine-removing 17, the reverse vine-removing 18, and the feeding auger 15. The melons are then conveyed to the top by the seed melon elevator auger and slide into the melon crushing chamber 31. The gourds and melons then pass through the melon-cutting blade shaft 20 and the melon-pressing roller 21 in the melon crushing chamber 31 to cut and press the melons, exposing some of the seeds. The cut gourds and melons fall into the threshing machine.

[0059] The grains are separated by the interaction between the roller 29 and the concave plate and fall into the grain bottom shell 32 below. The rind is discharged from the body with the end of the roller. Then the grain conveying auger 22 pushes the grains into the left slurry cylinder 23 and the right slurry cylinder 24. After passing through the inner baffle and the side wall of the slurry cylinder, the pulp in the grains is separated and then falls into the horizontal grain conveyor 28. Then the vertical grain elevator 25 sends the grains to the fruit box 26. After the fruit box 26 is full, the fruit box cylinder 9 is raised to load the grains into the transfer vehicle.

[0060] According to the embodiments of this application, the seed melon combine harvester uses a transfer case and a fully hydraulic motor to drive the working parts to walk and harvest. The machine has low noise and overcomes the problems caused by belt and chain transmission.

[0061] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application.
