Abstract
Description
Technical Field
[0001] This utility model relates to the field of silage cutting platform technology, and more specifically, to a double-disc silage cutting platform. Background Technology
[0002] A silage cutter is an important piece of agricultural machinery used for harvesting and processing silage. Silage refers to feed made by chopping, compacting, and sealing fresh plant material (such as corn, sorghum, and forage grass) in silage pits or bags, and then preserving it through anaerobic fermentation. The main function of a silage cutter is to cut these plant materials into lengths suitable for silage and collect them for further processing and storage. A double-disc silage cutter is a common type of silage harvesting equipment, characterized by the use of two rotating disc blades to cut the plant material.
[0003] Double-disc silage headers inevitably encounter situations where grass or plant material gets tangled or wrapped around them during use, requiring cleaning. However, most existing headers are fixed with bolts, making disassembly and cleaning quite troublesome.
[0004] Furthermore, most silage cutting platforms are fixedly installed on the outside of the support frame, which makes it impossible to flexibly adjust the height of the cutting platform according to the height of the plant material, resulting in poor flexibility in use. Utility Model Content

[0031] In this embodiment, mounting brackets 16 are fixedly provided on the inner wall of the bracket 15 on both sides, and hinge blocks 14 are hinged to the mounting brackets 16. A connecting rod 17 is fixedly provided at the bottom of the horizontal plate 2 and in the middle of the two lifting plates 1. An electric push rod 18 is hinged on the outer wall of the bracket 15 and at the bottom. The output end of the electric push rod 18 is hinged to the connecting rod 17.
[0032] More specifically, the user can disengage the locking pin 12 by rotating the limiting nut 13, at which point the locking pin 12 can be pulled out from the locking hole 11 to separate the insert rod 9 and the rotating shaft 6, thereby disassembling the cutter body 10 for easy cleaning. During cutting, the user can also control the electric push rod 18 to move the connecting rod 17 and the lifting plate 1, thereby adjusting the height and angle of the cutter body 10 to facilitate cutting plant materials of different heights, increasing the flexibility of the device during use.
[0033] Please see Figure 1 and Figure 4 As an embodiment for connecting the device and the motorized equipment: an external mechanism is provided at the rear end of the bracket 15. The external mechanism includes an external frame 19. Two sets of external frames 19 are provided and are fixedly connected to the bracket 15. A through hole 20 is opened on the upper end face of each external frame 19. A pin 21 is movably provided inside the through hole 20. A fastening nut 22 is provided at the bottom of each pin 21. The fastening nut 22 is threaded to the outer wall of the pin 21. A pull ring 23 is fixedly provided on the upper end face of each pin 21.
[0034] Specifically, the user can remove the fastening nut 22 to take out the pin 21 from the inside of the external frame 19. At this time, the bracket 15 can be connected to the external motor equipment through the external frame 19. Finally, it can be fixed by the pin 21 and the fastening nut 22 to facilitate the movement of the device.

[0036] Specifically, during cutting, the motor 24 can be turned on to make the spur gear 25 drive the transmission shaft 4 and the first bevel gear 5 to rotate. At this time, the first bevel gear 5 will drive the second bevel gear 7 and the rotating shaft 6 to rotate, so that the cutting table body 10 can cut the plant material for easy use.
[0037] In summary, when using the overall equipment: the user can first remove the fastening nut 22 to remove the pin 21 from the inside of the external frame 19. Then, the bracket 15 can be connected to external motorized equipment via the external frame 19. Finally, it can be fixed using the pin 21 and the fastening nut 22 for easy movement of the device. During cutting, the motor 24 can be turned on to drive the spur gear 25 to rotate the transmission shaft 4 and the first bevel gear 5. The first bevel gear 5 will then drive the second bevel gear 7 and the rotating shaft 6 to rotate, allowing the cutting table body 10 to cut the plant material. This is convenient to use and also allows for... The output end of the electric push rod 18 is used to move the connecting rod 17 and the lifting plate 1, thereby adjusting the height and angle of the cutter body 10. This facilitates the cutting of plant materials of different heights and increases the flexibility of the device during use. When it is necessary to disassemble the cutter body 10, the user can rotate the limit nut 13 to disengage it from the locking pin 12. At this time, the locking pin 12 can be pulled out from the inside of the locking hole 11 to separate the insert rod 9 and the rotating shaft 6, thereby achieving the effect of disassembling the cutter body 10 and facilitating the cleaning of tangled plant materials or weeds.
