Referring to FIGS. 3-7, the grass clipper 12 includes a bracket 120, a roller 130, and a drive assembly 150, which are discussed in detail below.

Specifically, the stand 120 is used for connection with the pickup 11 or other structures for supporting the roller 130, etc., and the structure of the stand 120 is not limited, and in this embodiment, the following schemes may be adopted, but are not limited to: referring to fig. 8, the bracket 120 includes a stay 121 and two support plates 122. The support plates 122 are of plate-shaped structures, the shapes of the support plates are not limited, the two support plates 122 are oppositely arranged, the support rods 121 are arranged between the two support plates 122, two ends of the support rods 121 are respectively connected with the two support plates 122, and the support rods 121 are used for enhancing the strength of the support 120. The connection manner of the support plate 122 and the pickup 11 is not limited, and for example, the pickup 11 includes a frame, and the rear end of the support plate 122 is connected to the frame by bolts. In some embodiments, the support plate 122 may be rotatably connected to the frame, specifically, the frame is provided with a rotating shaft 132, and the rear end of the support plate 122 is rotatably sleeved on the rotating shaft 132. In other embodiments, the bracket 120 may take other configurations, such as a frame configuration, etc.

The roller 130 is located between the two support plates 122, and two ends of the roller 130 are rotatably connected with the two support plates 122 respectively. The shape and structure of the roller 130 are not limited, and for example, the roller 130 may be cylindrical, prismatic, etc., in this embodiment, as shown in fig. 9, the roller 130 is prismatic, the roller 130 includes a rotating shaft 132 and a cylinder 133, the cylinder 133 is coaxially disposed with the rotating shaft 132, and the rotating shaft 132 penetrates through two ends of the cylinder 133 and is rotatably supported by two support plates 122 respectively. Barrel 133 is hollow, and specifically, barrel 133 includes barrel board and two end plates, and the barrel board is tubular structure roughly, and two end plates are located the both ends of barrel board and seal the both ends of barrel board, and pivot 132 is located to the end plate cover, and pivot 132 rotates, can drive barrel 133 and rotate.

In addition, the outer surface of the roller 130 is provided with at least two rake plates 131, the rake plates 131 extending along the edges of the roller 130. The rake plate 131 can rake the material backwards, and is not easy to slip.

The number of the rollers 130 is not limited, for example, the number of the rollers 130 is one, two, three, etc., in order to make the material transportation smoother and less prone to grass blocking and stacking, the number of the rollers 130 may be more than two, in this embodiment, the grass presser 12 includes three rollers 130, the three rollers 130 are parallel and spaced, that is, the center lines of the three rollers 130 are parallel, and the three rollers 130 are sequentially arranged along the feeding direction of the material. The centerlines of the three rollers 130 may or may not be coplanar, and in order to allow sufficient material contact with the rollers 130, in this embodiment, the three rollers 130 are arcuately distributed, i.e., the centerlines of the three rollers 130 are not coplanar.

The three rollers 130 are defined as a first roller, a second roller, and a third roller from front to back, respectively, and the pickup 11 includes a pickup portion that is rotatable, wherein the first roller is located above or directly in front of the pickup portion, and the second roller and the third roller are located above or directly behind the pickup portion.

In some embodiments, a baffle 140 may be disposed between the first roller and the second roller, the baffle 140 being located directly above the pick-up section, the baffle 140 being progressively farther from the baler's pick-up 11 in the feed direction. The baffle 140 can adopt flat plate structure, bending plate structure, arc plate structure, etc., the front end of the baffle 140 can be consistent with the middle part of the first roller in height, and the rear end of the baffle 140 can be consistent with the top end of the second roller in height. The baffle 140 is configured to allow material to be removed from the first roller and transported to the second roller as quickly as possible.

If the roller 130 passively rotates, that is, the pickup 11 rotates and drives the material to move backward, when the material contacts and extrudes with the roller 130, the roller 130 can be driven to rotate, if the extrusion force between the material and the roller 130 is smaller, the roller 130 is not easy to drive, the material may be clamped and piled up, and the passively rotated roller 130 makes the conveying efficiency of the pickup mechanism 10 lower, which is needless to say. Therefore, in this embodiment, the roller 130 is driven by the driving component 150, so that the roller 130 can actively rotate, and the material can be conveyed backward more smoothly, so that the conveying efficiency of the material is effectively improved, and the material is prevented from accumulating.

For example, the driving assembly 150 adopts a motor, the motor is mounted on the bracket 120 or the pickup 11 or the bundling machine, taking three rollers 130 as an example, the three rollers 130 are respectively a first roller, a second roller and a third roller, two ends of the first roller are respectively provided with a sprocket, the same ends of the second roller and the third roller are respectively provided with a sprocket, an output shaft of the motor is also provided with a sprocket, the sprocket of the motor and the sprocket of the first roller are in chain transmission, and the same ends of the first roller, the second roller and the third roller are in chain transmission. Of course, in some embodiments, the drive assembly 150 may also drive other assemblies synchronously.

The driving assembly 150 may be provided independently or may be shared with the pickup 11, that is, the driving assembly 150 may be capable of driving the drum 130 to rotate and driving the pickup portion of the pickup 11 to rotate.

The pickup mechanism 10 provided in this embodiment works as follows:

the pick-up mechanism 10 is arranged below, the pick-up 11 is arranged below and adjacent to the ground, the pick-up 11 and the driving assembly 150 are started, the pick-up part of the pick-up 11 can rotate, and the driving assembly 150 can drive the roller 130 to actively rotate;
