[0018] like Figure 1-5 As shown, a novel picker includes a picking mechanism, an auxiliary feeding mechanism, a feeding mechanism and a depth-limiting roller 13.

[0019] The picking mechanism includes a fixed side plate 1 of the picker, a grass baffle 2, a movable side plate 3 of the picker, a grass repelling roller 10 and a secondary picking mechanism. The grass baffle 2 is located on the top of a pair of fixed side plates 1 of the picker, and is used to block the grass material thrown up and scrape the grass residue on the strong feeding rotor 4. The grass baffle 2 is provided with a number of slots with equal spacing, which are used to make way for the rotation range of the tooth ring on the strong feeding rotor 4 and scrape the side wall of the tooth ring at the same time.

[0020] An auxiliary feeding mechanism is provided between the fixed side plate 1 of the pickup at the front end of the grass baffle 2. The auxiliary feeding mechanism should collect the grass that is thrown out by the grass roller 10 and has not entered the strong feeding mechanism to improve the picking effect. The auxiliary feeding mechanism includes a grass guide roller 5, a grass feeding swing arm 6, a grass spreading roller 7, and a buckle plate 8. A grass guide roller 5 is provided between the fixed side plate 1 of the pickup in front of the grass baffle 2. Grass feeding swing arms 6 hinged to the fixed side plate 1 of the pickup are provided at both ends of the grass guide roller 5. Positioning screws threaded into the fixed side plate 1 of the pickup are provided on the side wall of the grass feeding swing arm 6. Grass spreading roller 7 is provided between the ends of the grass feeding swing arm 6. A buckle plate 8 that covers both the grass guide roller 5 and the grass spreading roller 7 is provided between the tops of the grass feeding swing arm 6. One end of the grass guide roller 5 and the grass spreading roller 7 are synchronously connected through a sprocket and a chain.

[0021] The rear end of the fixed side plate 1 of the pickup is fixedly connected to the baler, and the bottom of the fixed side plate 1 of the pickup is hinged with a movable side plate 3 of the pickup. A main grass-reeling roller adjusting cylinder 31 is provided between the fixed side plate 1 of the pickup and the movable side plate 3 of the pickup, which is used to lift the grass-reeling roller 10 mechanism when the equipment moves to prevent it from touching the ground. At the same time, during the picking process, the oil inlet and return valves in the cylinder are opened at the same time, and the grass-reeling roller 10 plays a damping and buffering role when it swings with the ups and downs of the ground. A depth-limiting roller 13 is provided between the movable side plates 3 of the pickup behind the secondary picking mechanism. The depth-limiting roller 13 is slightly lower than the outer wall of the roller body of the grass-reeling roller 10. Due to limiting the height of the grass-reeling roller 10, excessive penetration into the soil is avoided.

[0022] A grass-reeling roller 10 is provided between the front ends of the movable side plate 3 of the picker, and a secondary picking mechanism is provided between the movable side plate 3 of the picker behind the grass-reeling roller 10. The secondary picking mechanism includes a slide plate 11, an auxiliary grass-reeling roller 12, and an auxiliary roller adjusting cylinder 14.

When the depth-limiting roller 13 contacts the ground, the furrow is located below the depth-limiting roller 13, so the depth of the auxiliary grass-grassing roller 12 entering the furrow can be controlled by the auxiliary roller adjusting cylinder 31. At the same time, consistent with the principle of the grass-grassing roller adjusting cylinder 31, when working, the oil inlet and return valves are opened, and the auxiliary grass-grassing roller 12 enters the furrow under its own weight, and at the same time plays a damping and buffering role as the furrow rises and falls.

[0023] A feeding mechanism is provided between the fixed side plates 1 of the pickup just above the grass-elasticating roller 10. Compared with the conventional mechanism located behind the ejecting roller 10, the feeding stroke is greatly shortened. The feeding mechanism includes a strong feeding rotor 4 and a grass feeding plate 9. The grass feeding plate 9 is located between the movable side plates 3 of the pickup divided behind the axis of the grass-elasticating roller 10. The rear end of the grass feeding plate 9 extends upward to the rear end of the hinge axis tangent of the movable side plate 3 of the pickup. The strong feeding rotor 4 is located between the fixed side plates 1 of the pickup divided just above the grass-elasticating roller 10. The strong feeding rotor 4 is also located between the grass baffle plate 2 and the grass feeding plate 9, and there is a certain distance between the outer circle of the teeth and the grass feeding plate 9.

[0024] The grass-grabbing roller 10 is connected to the baler driving mechanism through a sprocket and a chain, the auxiliary grass-grabbing roller 12 of the secondary picking mechanism is connected to the grass-grabbing roller 10 through a sprocket and a chain, and rotates in the same direction; the strong feeding rotor 4 is connected to the grass-grabbing roller 10 through a sprocket and a chain, and rotates in opposite directions; the other end of the grass-guide roller 5 of the auxiliary feeding mechanism is connected to the strong feeding rotor 4 through a sprocket and a chain, and rotates in the same direction.

[0025] A plurality of acute-angled triangular gear rings 41 are arranged at equal intervals on the forced feeding rotor 4. The acute-angled triangular gear rings 41 are composed of shift teeth and gear rings with acute-angled triangular cross-sections. A pair of shift teeth with acute-angled triangular cross-sections symmetrical about the center point of the gear rings are fixedly connected to the side walls of the gear rings. The middle acute-angled triangular gear ring 41 and the two outermost acute-angled triangular gear rings 41 on the forced feeding rotor 4 have the same angular direction, and are staggered in equal angles in the same direction from the middle to the two ends.
