[0045] The following is combined Figures 1-11 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] In a first aspect, this utility model provides a support and protection device for supporting a drum cover 1, comprising at least one protection unit; the protection unit includes a first mounting base 3, a second mounting base 5, a first support plate 4, a second support plate 6, a first anti-blocking part 8, and a second anti-blocking part 9; the first mounting base 3 is used to rotatably mount the first support plate 4 on the drum cover 1, and the second mounting base 5 is used to rotatably mount the second support plate 6 on the threshing machine body; the first support plate 4 and the second support plate 6 are rotatably connected by a rotating shaft 7; the first anti-blocking part 8 is disposed on the first support plate 4, and the second anti-blocking part 9 is disposed on the second support plate 6, and after the first support plate 4 and the second support plate 6 are folded by rotation, the first anti-blocking part 8 and the second anti-blocking part 9 are respectively located on opposite sides of the rotating shaft 7, and can abut against each other when the first support plate 4 and the second support plate 6 rotate in opposite directions, preventing the first support plate 4 and the second support plate 6 from folding in opposite directions.

[0047] In this embodiment, the first mounting base 3 is fixedly mounted on the drum cover 1, the second mounting base 5 is fixedly mounted on the threshing machine body, one end of the first support plate 4 is rotatably connected to the first mounting base 3 through a pin, and the other end is rotatably connected to one end of the second support plate 6 through a rotating shaft 7, and the other end of the second support plate 6 is rotatably connected to the second mounting base 5 through a pin.

[0048] Specifically, in this embodiment, one end of the first support plate 4 has a pin hole 11 and the other end has a rotating hole. One end of the second support plate 6 has a pin hole 11 and the other end is fixedly provided with a rotating shaft 7. The rotating shaft 7 is inserted into the rotating hole, so that the first support plate 4 and the second support plate can rotate relative to each other.

[0049] Both the first anti-reverse stop 8 and the second anti-reverse stop 9 are located on the outer side, that is, the first anti-reverse stop 8 is on the side of the first support plate 4 away from the roller, and the second anti-reverse stop 9 is on the side of the second support plate 6 away from the roller. This arrangement can avoid the influence of the roller cover 1 on the first anti-reverse stop 8 and the second anti-reverse stop 9, while ensuring the support space for the first anti-reverse stop 8 and the second anti-reverse stop 9.

[0050] When the gas spring 2 is in the contracted state, the roller cover 1 is in the closed state, and the first support plate 4 and the second support plate 6 are in the folded state. When the gas spring 2 is in the extended support state, the roller cover 1 is in the open state, and the second support plate 6 is in the open state, with the first support plate 4 and the second support plate 6 forming an obtuse angle with the opening facing obliquely upward.

[0051] During the process of the roller cover 1 changing from the closed state to the open state, the gas spring 2 extends and opens the roller cover 1. At the same time, the first support plate 4 and the second support plate 6 rotate relative to each other, changing from the folded state to the obtuse angle state with the opening facing upwards. During the process of the roller cover 1 changing from the open state to the closed state, the first support plate 4 and the second support plate 6 are pushed first to apply an upward force. At the same time, the gas spring 2 contracts, causing the roller cover 1 to rotate downwards to close. At the same time, the first support plate 4 and the second support plate 6 begin to fold until the roller cover 1 is completely closed, and the first support plate 4 and the second support plate 6 complete the folding.

[0052] In this embodiment, when the gas spring 2 suddenly fails while in a supported state, the roller cover 1 rotates downward under the action of gravity, and both the first support plate 4 and the second support plate 6 rotate downward under the action of gravity. Figure 3 As shown, at this time, the first anti-blocking part 8 and the second anti-blocking part 9 are in contact and abut against each other, so that the first support plate 4 and the second support plate 6 cannot continue to rotate, forcibly opening the first support plate 4 and the second support plate 6 to form a support frame that supports the drum cover 1, preventing the drum cover 1 from directly covering the threshing machine body, and also avoiding impact on the operators who are working under the drum cover 1, thus playing a better protective role.

[0053] In an optional embodiment, the first anti-blocking part 8 is a bent edge on the first support plate 4; the second anti-blocking part 9 is a bent edge on the second support plate 6.

[0054] In this embodiment, the widths of the first support plate 4 and the second support plate 6 are different, or the distance between the axis of the rotating shaft 7 and the second anti-blocking part 9 is greater than the distance between the axis of the rotating hole and the first anti-blocking part 8, so that the first support plate 4 and the second support plate 6 can be stacked, and the bent edge will not affect the mutual rotation of the first support plate 4 and the second support plate 6.

[0055] The setting mode can facilitate the processing and production of the first reverse blocking part 8 and the second reverse blocking part 9, and only the excess part of the first supporting plate 4 and the second supporting plate 6 needs to be bent. The width of the bent part can be adjusted according to actual needs, as long as the supporting force as the reverse blocking part can be met.

[0056] In an optional embodiment, the length of the bent part is the same as the length of the first supporting plate 4 or the second supporting plate 6.

[0057] In the embodiment, the setting is that the whole edge of the first supporting plate 4 and the second supporting plate 6 is bent.

[0058] The setting mode can facilitate the processing and production of the first reverse blocking part 8 and the second reverse blocking part 9, and only the excess part of the first supporting plate 4 and the second supporting plate 6 needs to be bent. The width of the bent part can be adjusted according to actual needs, as long as the supporting force as the reverse blocking part can be met.

[0059] The first supporting plate 4 and the second supporting plate 6 are both produced as common strip-shaped plates, and only one long edge of the strip-shaped plate needs to be bent.

[0060] When the drum cover 1 is opened, the bent edges of the first supporting plate 4 and the second supporting plate 6 of the supporting protection device as the first reverse blocking part 8 and the second reverse blocking part 9 will contact together to play a supporting role, that is, the first supporting plate 4 and the second supporting plate 6 will play a supporting role in the case that the gas spring 2 fails, as shown in Figure 3 and Figure 5 When the drum cover 1 needs to be closed, the two supporting plates only need to be lifted in the opposite direction manually.

[0061] In an optional embodiment, the end of the bent part is provided with a rounded corner.

[0062] In the embodiment, after the end of the bent part is provided with a rounded corner, the right-angle edge of the bent part can avoid a large impact on the other bent part, so as to damage the other bent part.

[0063] In the embodiment, the end of the bent part is provided with a rounded corner, but it is not limited to only this setting mode, and the position where the first reverse blocking part 8 and the second reverse blocking part 9 abut against each other can also be provided with a plane, that is, a plane contact is formed, which reduces the damage between each other, improves the service life of the first supporting plate 4 and the second supporting plate 6, and increases the supporting force between the first supporting plate 4 and the second supporting plate 6 and the stability during supporting.

[0064] In an optional embodiment, as shown in Figure 10As shown, the first anti-blocking part 8 is a vertical plate, which is arranged at the end of the first support plate 4 away from the first mounting base 3, and the vertical plate and the second support plate 6 are arranged at the same side of the first support plate 4; the second anti-blocking part 9 is a vertical column, which is arranged at the end of the second support plate 6 away from the second mounting base.

[0065] In the embodiment, the first anti-blocking part 8 is arranged as a vertical plate or a shaft end blocking ring; and the second anti-blocking part 9 is a cylindrical structure.

[0066] In the installation process, the vertical plate and the vertical column are fixed on the first support plate 4 and the second support plate 6 by screws.

[0067] Such arrangement can reduce the material requirement of the first anti-blocking part 8 and the second anti-blocking part 9, reduce the material use cost, and the installation method is simple and fast. For the first support plate 4 and the second support plate 6 with different widths, the relative position between the first support plate 4 and the second support plate 6 can be adjusted in time, so as to ensure the supporting force and effect between the first support plate 4 and the second support plate 6.

[0068] In the optional embodiment, as shown in Figure 8 and Figure 9 , one end of the rotating shaft 7 is fixedly arranged on the first support plate 4 or the second support plate 6, and the other end of the rotating shaft 7 is provided with a shaft end blocking ring 12 for preventing the second support plate 6 or the first support plate 4 from being separated from the rotating shaft 7; as shown in Figure 4 , Figure 5 and Figure 6 , the second support plate 6 or the first support plate 4 is provided with a rotating hole, and the rotating shaft 7 is arranged through the rotating hole; the rotating hole is a strip-shaped hole 10.

[0069] In the embodiment, the first support plate 4 and the second support plate 6 are rotationally connected through the cooperation of the rotating shaft 7 and the rotating hole, and the shaft end blocking ring 12 is used to prevent the rotating shaft 7 from being separated from the rotating hole, so as to ensure the connection stability of the first support plate 4 and the second support plate 6.

[0070] Specifically, in the embodiment, the rotating hole is arranged as a strip-shaped hole 10, the relative position between the first support plate 4 and the second support plate 6 can be adjusted by the sliding of the rotating shaft 7 in the strip-shaped hole 10, so that after the air spring 2 supports the roller cover 1, the first support plate 4 and the second support plate 6 can be first rotated downward under the action of gravity, i.e. Figure 5As shown, the first support plate 4 rotates clockwise, and the second support plate 6 rotates counterclockwise, so that the first support plate 4 and the second support plate 6 are not in a straight line, and when the air spring 2 fails and the drum cover 1 falls, the first support plate 4 and the second support plate 6 can continue to rotate downward under the action of the drum cover 1, and the first reverse blocking part 8 and the second reverse blocking part 9 begin to abut each other to support, realizing the supporting effect of the drum cover 1.

[0071] In an optional embodiment, when the first support plate 4 and the second support plate 6 are in a straight line by rotating, the first reverse blocking part 8 and the second reverse blocking part 9 have a gap therebetween, so that the first support plate 4 and the second support plate 6 can continue to rotate relative to each other under the action of gravity.

[0072] In this embodiment, the first reverse blocking part 8 and the second reverse blocking part 9 have a gap therebetween when the first support plate 4 and the second support plate 6 are in a straight line, and can rotate downward to a certain extent under the action of gravity, thereby forming stable support, and when the air spring 2 fails and the drum cover 1 falls, the supporting force and supporting effect are ensured.

[0073] In an optional embodiment, the number of protection units is two; two protection units are respectively arranged on opposite sides of the drum cover.
