The swinging frame 11 is used for receiving and conveying the batching when the pushing rod 8 horizontally pushes the reciprocating swinging.

And a track group which comprises two track panels 12, wherein the two track panels 12 are opposite and fixed on two sides of the frame 1 at the position near the end point of the conveying path of the batching reciprocating conveying mechanism 4.

And a swing device fixedly installed on the track panel 12, the lower portion of the guide bar 14, which can have a multi-angle vertical displacement in cooperation with the swing device, being fixed on the side frame 16 of the swing frame 11, so that the swing frame 11 can swing along with the guide bar 14 due to the fixing of the swing device on the track panel 12.

It can be understood that the guide rod 14 is fixed with the swing frame 11, the guide rod is mounted on the swing device, and the swing device enables the guide rod to have multi-angle vertical displacement, namely the guide rod forms a swing motion track, and drives the swing frame fixed on the guide rod to form a swing motion track.

The push rod 8 moves backwards to pull the swing mechanism 9 to swing backwards, and the push rod 8 moves forwards to push the swing mechanism 9 to swing forwards.

The plane of the swing mechanism 9 is vertical to the horizontal plane, and in the initial position: the push rod 8 moves forward to push the swing mechanism 9 to swing forward, namely, the swing frame 11 is pushed forward, and the guide rod 14 fixed with the swing frame 11 moves forward and downward because the upper end part is restrained by the swing device. The reason for this is that the swing frame 11 tends to move forward when pushed, and since the swing frame 11 is fixed to the guide bar 14, if the guide bar 14 is attached to the track panel 12 and the track panel 12 is fixed to the frame 1, the swing frame 11 is fixed to the frame 1 and cannot be pushed forward. The invention sets up the upper end of the guide lever 14 to mount inside the swing device, the swing device is fixed on the track panel 12, the track panel 12 is fixed on framework 1, the swing device can allow the guide lever 14 to swing back and forth with it as the swing base point, therefore the swing frame 11 is pushed forward, the guide lever 14 fixed with the swing frame 11 moves forward and downward because of the upper end because of the constraint of the swing device.

When the push rod 8 moves forward and pushes the swing mechanism 9 to swing forward, that is, pushes the swing frame 11 forward, the swing frame 11 is pushed forward, and the guide rod 14 fixed to the swing frame 11 moves forward and upward due to the constraint of the swing device at the upper end. And restoring the position of the surface of the swing mechanism 9, which is vertical to the horizontal plane.

This structure makes pile up preceding mud and lay on the batching promptly, need not to consider the synchronism problem to it is even to lay, and the basket opening part does not shelter from and spatial structure is compact and reasonable, can not hinder the batching conveying, and the swing is laid efficiency height.

Preferably, at least one fixing portion extends from a lower portion of the side plate frame 16 of the swing frame 11 to both sides, and the fixing portion is fixed to the end portion of the fixing portion by limiting the guide rod 14 at the end portion of the fixing portion by a clamp plate connected to the end portion, so that the lower portion of the guide rod 14 is fixed to the fixing portion of the side plate frame 16 of the swing frame 11. The fixing stability of the swing frame 11 and the guide bar 14 can be improved.

Preferably, the swing frame 11 of the swing mechanism 9 is mainly formed by connecting two panel frames 15 which are gradually inclined through side plate frames 16 to form a frame 1 which is wide at the top and narrow at the bottom, the wide opening at the top is an inlet of the double-layer cloth for coating the sludge, the narrow opening at the bottom is an outlet of the double-layer cloth for coating the sludge, and the wide-top and narrow-bottom hollow part of the frame 1 can enable the double-layer cloth for coating the sludge to pass through. The form of the swing frame 11 with wide top and narrow bottom can prevent the rolled cloth from entering the swing frame 11 and achieve the effect of uniform laying after being output from the outlet.

Preferably, one of the two face plate frames 15 which is further away from the push rod 8 has its upper end extending obliquely away from the push rod 8 and beyond the original inclination of the face plate frame, and the face plate frame 15 is made higher than the other face plate frame 15. The cloth rolling inertia can be buffered, and the phenomenon that the cloth is easy to rush out of the panel frame 15 due to the fact that the cloth is conveyed and turned between the cloth rolling reciprocating conveying mechanism 4 and the swing frame 11 is avoided as much as possible.
