[0024] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0025] like Figure 1-3 As shown, the unloading guide plate 1, the guard 2, the tire 3, the lubrication system 4, the hydraulic system 5, the baling mechanism 6, the feeding mechanism 7, the header assembly 8, the baling roller 8, the frame 10, the platform 11, the connecting traction frame 12, the transmission shaft 13, and the electric control 14, the auger 15, the first auger blade 16, and the second auger blade 17;

[0026] A round grass bale baler for a harvester, the overall structure of which is as follows Figure 1 As shown, multiple key components are integrated to achieve efficient and continuous baling operation. The machine is mainly composed of a bale unloading guide plate 1, a guard 2, a tire 3, a lubrication system 4, a hydraulic system 5, a baling mechanism 6, a feeding mechanism 7, a header assembly 8, a baling roller 8, a frame 10, a platform 11, a connecting traction frame 12, a transmission shaft 13 and an electronic control system 14. The various components are closely linked to each other to complete the entire process from grass harvesting to baling.

[0027] When the operation starts, the header assembly 8 first plays a role. Figure 3 As shown, it is responsible for smoothly cutting the standing stalks and conveying them to the conveying area of ​​the feeding mechanism 7. Specifically, after the cutting knife of the cutting table cuts off the roots, the cut-off non-root cup and other subsequent materials are pushed into the working area of ​​the auger 15 and conveyed by the auger 15. The auger 15 includes an auger shaft, a first auger blade 16, and a second auger blade 17. The first auger blade 16 is a right spiral blade located on the left section of the auger shaft. The second auger blade is a left spiral blade 16 located on the right section of the auger shaft. The middle section of the auger 15 shaft is a vacuum section, which leads to the feeding mechanism 7. That is to say, there is no blade in the middle of the auger 15 shaft, and the spiral blades at both ends convey the materials to the middle, and then the feeding mechanism 7 conveys the crop roots to the baling mechanism;

[0028] The feeding mechanism 7 is responsible for continuously conveying the cut grass to the baling drum 8. Driven by a cleverly designed transmission chain, the baling drum 8 makes the material entering the baling chamber move in a specific direction and is gradually compressed into a bale under the action of centrifugal force.

[0029] At the same time, the lubrication system 4 continuously provides lubrication and oil supply for the bearings of each transmission part to ensure smooth operation of the machine, reduce wear and tear, and thus extend the service life of the machine. In addition, the lubrication system 4 also refuels each transmission chain to maintain its good operating state.

[0030] When the bale reaches the preset density under the action of the baling drum 8, the hydraulic system 5 starts to work. It controls the opening and closing of the bag behind the baling chamber to ensure that the bale can be baled accurately. At this time, the material level detection sensor equipped on the hydraulic system 5 will monitor the density of the bale in real time and send a signal to the control terminal. After receiving the signal, the control terminal will promptly issue a net laying instruction to start the packaging mechanism 6 to automatically lay the net.

[0031] The packing mechanism 6 has an automatic net laying function, and the number of net winding circles can be adjusted as needed. Its independently developed electric clutch ensures the accuracy and sensitivity of the action, making the net laying process fast and reliable. After the net is laid, the unloading guide plate 1 starts to play a role, which ensures that the bale can roll back smoothly after leaving the backpack without affecting the closing of the backpack. At the same time, an automatic collection device for the number of bales is also equipped here to record the number of bales.

[0032] The frame 10 is a supporting structure of the whole machine and has sufficient strength and rigidity. It is composed of a front backpack of the baling chamber and a rear backpack of the baling chamber, wherein the rear backpack has an opening and closing function centered on the baling drum 8, further ensuring the smooth bale packing.

[0033] The platform 11 provides a space for the operator to replace and store the net rolls, and is equipped with a fire extinguisher to prevent accidental fire. The unique design of the connecting traction frame 12 ensures that the machine can be reliably connected to tractors of different brands and manufacturers, which is safe and convenient, greatly expanding the scope of application of the machine.

[0034] Finally, as the core part of the intelligent control of the round hay baler, the electronic control system has two control modes: automatic and manual. It is equipped with a counting function, which can flexibly set the time between the action instructions of each mechanism. At the same time, the electronic control system also has the characteristics of image pictographic display and can be operated by buttons, which is convenient for the driver to make real-time adjustments according to the material status and the actual field conditions, so as to ensure that the machine is always in the best working condition.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
