DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 A flip cover of a field return machine includes an upper machine beam 1, a rear machine beam 2 and a movable cover plate 3. The upper machine beam 1 and the rear machine beam 2 are both commonly used crossbeam structures of field return machines. The rear machine beam 2 is arranged at the lower rear side of the upper machine beam 1. A connecting member 4 is arranged on the upper machine beam 1. A cover plate connecting portion 41 is arranged on the connecting member 4. The cover plate connecting portion 41 is used to connect the movable cover plate 3 with the upper machine beam 1. In order to enable the movable cover plate 3 to be stably installed on the upper machine beam 1 and to function stably during use, there are at least two and preferably three connecting members 4. An automatic drive member installation position 42 is also reserved on each connecting member 4, and the automatic drive member 7 is installed and connected to the automatic drive member installation position 42.

[0023] The outer end surface of the movable cover plate 3 is provided with a rotating arm 5, the front end of each rotating arm 5 is connected to the corresponding cover plate connection part 41 and the rotating arm 5 can rotate relative to the connection with the cover plate connection part 41, the movable cover plate 3 rotates relative to the connection between the rotating arm 5 and the cover plate connection part 41, when the rear end of the movable cover plate 3 contacts the rear machine beam 2, the movable cover plate 3 is in the closed position, and when the movable cover plate 3 flips up to the maximum limit, the movable cover plate 3 is in the open position. The rotating arm 5 is provided with a manual drive component connection position and an automatic drive component 7 connection position, the manual drive component connection position is used to install the manual drive component, so that the operator can directly drive the movable cover plate 3 to rotate between the open position and the closed position relative to the upper machine beam 1, the automatic drive component 7 connection position corresponds to the automatic drive component installation position 42, and the automatic drive component 7 connection position is used to connect with the automatic drive component 7 when the automatic drive component 7 is installed at the automatic drive component installation position 42, so that the automatic drive component 7 can drive the movable cover plate 3 to rotate between the open position and the closed position relative to the upper machine beam 1.

[0024] A manual lock installation position is also reserved at the rear end of the corresponding rotating support arm 5 on the rear machine beam 2. When the automatic drive component 7 is not used to control the flipping of the movable cover 3, a lock mechanism 8 is set at the manual lock installation position to prevent the movable cover 3 from opening uncontrollably during the use of the field return machine.

[0025] See also Figure 1 and Figure 2 In the embodiment of using a manual drive component to control the movable cover 3, a manual drive component is provided at the manual drive component connection position, and the manual drive component is a handle or other form of lifting member 6, which is convenient for the operator to manually drive the movable cover 3 to rotate. A locking mechanism 8 is provided at the manual lock installation position. When the movable cover 3 is rotated to the cover-closed position by the lifting member 6, the locking mechanism 8 and the rear end of the rotating support arm 5 are used to lock to the rear machine beam 2 to prevent the movable cover 3 from opening uncontrollably during the operation of the field return machine, thereby causing safety problems. When the movable cover 3 in the cover-closed position needs to be flipped to the open position, the locking mechanism 8 needs to be released first.

[0026] See also Figure 2 The locking mechanism 8 includes a locking seat, a locking pin and a buckle plate. The locking seat is arranged on the rear machine beam 2. The locking pin is arranged on the locking seat and rotates relative to the locking seat. A screw is vertically arranged on the locking pin. The buckle plate is arranged on the screw and moves along the screw. A locking area is arranged between the buckle plate and the locking pin. When the movable cover plate 3 is in the closed position, the rear end of the rotating arm 5 is located in the locking area, and the buckle plate moves along the screw toward the locking seat and presses the rotating arm 5 toward the locking seat. When the movable cover plate 3 in the closed position needs to be rotated to the open position, the buckle plate moves along the screw in a direction away from the locking seat. When the buckle plate moves to a position where it does not affect the rotation of the rotating arm 5, the movable cover plate 3 can be flipped.

[0027] The buckle plate is provided with a waist hole, through which a screw rod passes and a nut is provided on the screw rod. The buckle plate can be moved along the screw rod by rotating the nut to adjust the buckle plate. The hole on the buckle plate suitable for the screw rod to pass through is a waist hole, so that the buckle plate can move relative to the screw rod in the direction outward of the screw rod axis, thereby improving the convenience of unlocking the locking mechanism 8.

[0028] Furthermore, the rotating arm 5 includes two rotating arm plates, the plate surfaces of the two rotating arm plates are opposite to each other and are connected to the outer end surface of the movable cover plate 3, and the two rotating arm plates are also connected by a plurality of connecting rods. When the movable cover plate 3 is flipped to the covering position, the screw corresponding to the locking mechanism 8 is between the two rotating arm plates, and the locking plate of the locking mechanism 8 is in contact with and cooperates with the two rotating arm plates.

[0029] See also Figure 3 and Figure 4 In the embodiment of the automatic opening and closing movable cover 3, a bracket is provided at the automatic drive component installation position 42, and the bracket is detachably installed at the automatic drive component installation position 42 through a pin structure, so that the automatic drive component 7 can be disassembled together with the bracket when the automatic drive component 7 is not needed; the automatic drive component 7 is a telescopic component such as an oil cylinder or a gas cylinder, and the automatic drive component 7 is installed on the bracket and rotates relative to the bracket. The telescopic part of the automatic drive component 7 is rotatably connected to the connection position of the automatic drive component 7, and the automatic drive component 7 drives the movable cover 3 to rotate between the open position and the cover closing position. At this time, the lifting member 6 can still be provided at the manual drive component connection position of the rotating support arm 5, so as to flip the movable cover 3 when the automatic drive component 7 is repaired or replaced, but the locking mechanism 8 is not provided at the manual lock installation position, because during use, the position of the movable cover 3 can also be locked by using the telescopic component.
