[0033] Such as Figures 1 to 6As shown in the figure, the utility model discloses a grass cleaning device, which includes a lower bin d1, a double sprocket drum d2, a feeding roller d3, a supporting roller d4, and a transfer cylinder group d5. The lower bin d1 is rotatably connected to the frame of the round baler. Here, there is a pin shaft d11 on the lower bin d1, and a pin shaft d11 on the frame. The main body and the telescopic end of the hydraulic cylinder are respectively hinged to the two pin shafts d11, and the lower bin d1 is driven to rotate relative to the frame by the telescopic movement of the hydraulic cylinder. The double sprocket drum d2 is arranged on the lower bin d1 and is rotatably connected to the lower bin d1. The double sprocket drum d2 is used to assist the forage to be fed into the lower bin d1. Of course, it should be pointed out here that the forage mainly refers to forage grass and also includes materials such as straw, which are collectively referred to as forage in the utility model. The feeding roller d3 includes a first feeding reinforcing roller d31 and a second feeding reinforcing roller d32. Both ends of the first feeding reinforcing roller d31 and the second feeding reinforcing roller d32 are rotatably connected to the lower bin d1. The supporting roller d4 is located at the lower part of the front bin, and the supporting roller d4 can be turned over along with the front bin. The transfer cylinder group d5 is used to transfer the forage to the rear bin d8. Among them, a number of raised blocks d6 are provided on the first feeding reinforcing roller d31, the second feeding reinforcing roller d32, the supporting roller d4, and the transfer cylinder group d5.
[0034] In the present utility model, the frame, the rear bin d8, the lower bin d1, and the upper bin d7 all adopt existing technical means and will not be introduced in detail here.
[0035] Figure 2 、 3 shows the positional relationship of the lower bin d1 relative to the frame before and after rotation. When the equipment is working, the power of each drum and each roller comes from the gearbox or chain drive. When working, the forage enters the lower bin d1 from the left side of the equipment ( Figure 3 ), and first the double sprocket drum d2 feeds the forage into the inlet of the lower bin d1, then the forage is fed into the lower bin d1 through the two feeding rollers d3. After that, the forage forms a bale under the combined rotation of the first feeding reinforcing roller d31, the second feeding reinforcing roller d32, and the supporting roller d4. At the same time, the raised blocks d6 provided on each roller can prevent the forage from wedging between the two drums to cause blockage of the grass and can also play an auxiliary feeding role, realizing the function of improving the forming rate and preventing the forage from causing blockage.
[0036] When the bale is formed by rolling in the lower bin d1, the hydraulic cylinder drives the lower bin d1 to rotate, so that the lower bin d1 returns to its original position (as Figure 2 shown), the bale moves towards the rear bin d8 through the second feeding reinforcing roller d32, and moves to the rear bin d8 through the transfer cylinder group d5. Subsequently, the hydraulic cylinder drives the lower bin d1 to rotate so that the lower bin d1 is in the raised state (as Figure 3 shown), and then the processing operation of the next batch of forage can be carried out.
[0037] In the above embodiments, through the rotation of the lower bin d1 and the setting of the convex block d6, when the lower bin d1 returns to its position, the feeding roller d3 below drives the forage into the rear bin d8, improving the forming rate and preventing the forage from being blocked. When the lower bin d1 rises, the forage is removed by the forced separation roller above.
[0038] Optionally, as Figure 1 shown, a double-row sprocket is provided at one end of the double-sprocket drum d2, and a single sprocket d22 is provided at the other end of the double-sprocket drum d2. The double-row sprocket d21 serves both as a driven sprocket to receive the power transmitted by the front-side chain and as a driving sprocket to provide power for the entire lower bin d1 assembly. This ensures the driving power of each roller of the lower bin d1, and the chain connection can ensure that all the rollers rotate in the same direction and at the same speed, effectively preventing the forage from being blocked.
[0039] Optionally, as Figures 2 to 4 shown, driven sprockets d33 are provided at one end of the first feeding reinforcement roller d31 and the second feeding reinforcement roller d32. A tensioning sprocket d34 is provided on the lower bin d1. The double-row sprocket d21 is connected to the tensioning sprocket d34 and the two driven sprockets d33 through a driving chain d211 to drive the entire lower bin d1 assembly to move.
[0040] Optionally, as Figure 5 shown, the transfer drum group d5 includes a flat drum d51 and a forage transfer drum d52. The flat drum d51 is rotatably connected to the frame and is used to receive the forage from the second feeding reinforcement roller d32. The forage transfer drum d52 is used to transfer the forage to the rear bin d8.
[0041] Optionally, as Figure 5 shown, sprockets are provided at one end of the flat drum d51 and the forage transfer drum d52, and they are connected to the single sprocket d22 through a transfer chain d221. Such a setting can synchronously drive the transfer drum group d5 so that it has the same rotation speed and direction as each roller group of the lower bin d1.
[0042] Optionally, as Figure 5 shown, a second tensioning wheel d222 is provided outside the transfer chain d221, and the second tensioning wheel d222 is connected to the frame. Such a setting can prevent the transfer chain d221 from falling off.
[0043] Optionally, as Figure 1 , Figure 5 , Figure 6As shown, the driven sprocket d33 is connected to the first feeding reinforcing roller d31 through nuts and a expansion sleeve. The driven sprocket d33 is connected to the second feeding reinforcing roller d32 through nuts and a expansion sleeve. The sprocket is connected to the flat roller d51 through nuts and a expansion sleeve, and the sprocket is connected to the forage transfer roller d52 through nuts and a expansion sleeve. One end of the support roller d4 is provided with a sprocket, and the sprocket is connected to the support roller d4 through nuts and a expansion sleeve. Such a setting can ensure the stability of the installation of the driven sprocket or the sprocket, and improve the service life of the equipment. Optionally, the sprocket at one end of the support roller d4 is connected to other sprockets through a chain to ensure the rotation of the support roller d4.
[0044] Optionally, as Figure 6 shown, the raised block d6 is detachably connected to the first feeding reinforcing roller d31, the second feeding reinforcing roller d32, the support roller d4, and the transfer cylinder group d5. Such a setting can facilitate the installation and replacement of new or different types of raised blocks d6.
[0045] Optionally, as Figure 6 shown, the raised block d6 is welded to the first feeding reinforcing roller d31, the second feeding reinforcing roller d32, the support roller d4, and the transfer cylinder group d5.
[0046] In an embodiment of the present invention, a round baler is further provided, including the cleaning device described in any one of the above.
[0047] An application scenario of an exemplary embodiment:
[0048] As Figures 1 to 6 shown, the forage enters the lower bin d1 from the left side of the equipment. First, the forage is sent into the bin opening of the lower bin d1 through the double sprocket roller d2, and then the forage is fed into the lower bin d1 through two feeding rollers d3. After that, the forage forms a bale under the combined rotation of the first feeding reinforcing roller d31, the second feeding reinforcing roller d32, and the support roller d4. At the same time, the raised blocks d6 provided on each roller can prevent the forage from wedging between the two rollers and causing blockage of the grass, and can also play an auxiliary feeding role, realizing the function of improving the forming rate and preventing the forage from causing blockage. When the bale is formed by rolling in the lower bin d1, the hydraulic cylinder drives the lower bin d1 to rotate, so that the lower bin d1 returns to its original position (as Figure 2 shown), the bale moves in the direction of the rear bin d8 through the second feeding reinforcing roller d32, and moves to the rear bin d8 through the transfer cylinder group d5. Subsequently, the hydraulic cylinder drives the lower bin d1 to rotate so that the lower bin d1 is in a raised state (as Figure 3 shown), and then the processing operation of the next batch of forage can be carried out.
