[0002] Round bale baler pick -up mainly has two structures, one is cam disc structure, the other is cam disc structure without. The advantage of cam disc structure is that the rotating track of spring tooth piece is non-circular, which can well protect spring tooth piece, and the failure rate of spring tooth piece damage is low, while its disadvantage is that the processing of cam disc is relatively complex, and the manufacturing cost and failure rate are relatively high, and the replacement of spring tooth piece is not convenient. The advantage of cam disc structure without is that the structure is simple, the failure rate is low, and the replacement of spring tooth piece is convenient, and the disadvantage is that the rotating track of spring tooth piece is circular, and the failure rate of spring tooth piece damage will be relatively increased. Since spring tooth piece is a consumable, users pay more attention to the convenience of replacing spring tooth piece, so cam disc structure without gradually becomes the mainstream choice of round bale baler pick -up.

[0003] The existing pick -up of cam disc structure without in the market can only replace spring tooth piece outside pick -up when replacing spring tooth piece, so in order to facilitate the replacement of spring tooth piece, nut is usually welded inside mounting beam. When bundling operation of bundling machine is several hundred bales, spring tooth piece damage occurs. When the number of spring tooth piece replacement increases, the thread of nut welded inside mounting beam will be damaged. The strength of welded nut is low, and it is generally suitable for parts that are not frequently disassembled. Since pick -up of cam disc structure without is closed, it is difficult to replace welded nut. UTILITY MODEL CONTENTS

[0039] As shown in Figures 1 to 4 The present application discloses a pickup device, which comprises a rotating shaft 1 and a plurality of pickup beams 2. The pickup beams 2 are uniformly arranged around the rotating shaft 1. One side of the pickup beam 2 is a first side 21, and the other side is a second side 22. The second side 22 is recessed inward to form a groove 23. The pickup beam 2 has a through hole 24 and a waist-shaped hole 25. The through hole 24 and the waist-shaped hole 25 are located at the bottom of the groove 23, and the through hole 24 and the waist-shaped hole 25 are connected. The diameter of the through hole 24 is larger than that of the waist-shaped hole 25. The pickup beam 2 is also provided with a first limiting plate 26 and a second limiting plate 27. The first limiting plate 26 is arranged on the first side 21 of the pickup beam 2, and the first limiting plate 26 is located at one end of the waist-shaped hole 25 away from the through hole 24. The second limiting plate 27 is arranged on the second side 22 of the pickup beam 2, and the second limiting plate 27 is located on the side wall of the groove 23. A gap 28 is formed between the second limiting plate 27 and the bottom of the groove 23.

[0040] As shown in Figures 1 to 7As shown, the pickup also includes multiple sets of spring teeth. Multiple sets of spring teeth are arranged on each pickup beam 2, sequentially along the length of the pickup beam 2, with each set located at a groove 23. Each spring tooth set includes a spring tooth component 31, an arc-shaped washer 32, and a fixing bolt 5. The middle of the spring tooth component 31 is bent to form an assembly groove 33. Correspondingly, one end of the arc-shaped washer 32 has the assembly groove 33, and the other end has a locking interface 34, which is adapted to the second limiting plate 27. This arc-shaped washer 32 is a contour washer, allowing the spring tooth component 31 to fully engage with the arc-shaped washer 32, reducing uneven force distribution on the spring tooth component 31 after the fixing bolt 5 is tightened. A snap-fit ​​interface 34 is provided on the arc-shaped washer 32, which engages with the second limiting plate 27. When the fixing bolt 5 is tightened, the arc-shaped washer 32 is restricted from rotating by the second limiting plate 27, thus offsetting the friction caused by the rotation of the arc-shaped washer 32, freeing the user's hands, and ensuring that the elastic component remains parallel to the spring tooth component 31 after assembly. The fixing bolt 5 includes a fixing stud 51 and a fixing nut 52, with the fixing nut 52 detachably mounted on the fixing stud 51. The diameter of the through hole 24 is larger than the diameter of the fixing nut 52, and the diameter of the oblong hole 25 is greater than or equal to the outer diameter of the fixing stud 51.

[0041] An exemplary embodiment of the application scenario:

[0042] like Figures 1 to 7 As shown, a fixing nut 52 is placed on a fixing stud 51 to form a fixing bolt 5. The fixing stud 51 is placed in the assembly groove 33 of the spring tooth 31 and the assembly groove 33 of the arc-shaped washer 32. The arc-shaped washer 32 is located at the end of the spring tooth 31 away from the fixing nut 52. The fixing bolt 5, the spring tooth 31, and the arc-shaped washer 32 are placed in the groove 23 of the pickup beam 2. The end of the fixing stud 51 with the fixing nut 52 is passed through the through hole 24 on the pickup beam 2. Then, the fixing bolt 5, the spring tooth 31, and the arc-shaped washer 32 are placed in the groove 23 of the pickup beam 2. The three gaskets 32 slide together along the length of the oblong hole 25 to the end of the oblong hole 25 away from the through hole 24. At this time, the spring tooth 31 is located in the interlayer 28 between the second limiting plate 27 and the bottom of the groove 23, and the snap-fit ​​interface 34 of the arc-shaped gasket 32 ​​snaps into the second limiting plate 27 of the pickup beam 2. The first limiting plate 26 limits the fixing nut 52. Finally, the spring tooth 31 is fixed to the pickup beam 2 by rotating the fixing stud 51, thus achieving the purpose of detachably connecting the spring tooth 31 to the pickup beam 2. When the spring tooth 31 is damaged later, it can be removed and replaced simply by loosening the bolt. The operation can be performed on the outside of the pickup without disassembling the pickup, thus avoiding the wear and tear of the nut.

[0043] Optionally, such as Figure 8 , Figure 9As shown, the pickup beam 2 or the pickup guard is provided with a notch 35. After the fixing bolt 5 is loosened, it is moved to the through hole 24, and the fixing bolt 5 is taken out. If the fixing nut 52 falls into the pickup during the dismounting process, the pickup is started to rotate at a low speed, and the fixing nut 52 can fall from the notch 35. Thus, the replacement of the fixing bolt 5 is easy, and the replacement of the spring tooth member 31 is also easy.

[0044] Optionally, as shown in Figure 10 、 Figure 11 , the pickup further comprises an anti-falling member 6, the anti-falling member 6 has a limiting groove 61 with a U-shaped cross section, the limiting groove 61 has a slot 62 at the bottom, and the slot 62 is larger than the outer diameter of the fixing stud 51. The anti-falling member 6 is arranged on the first side surface 21 of the pickup beam 2. The limiting groove 61 is in communication with the through hole 24 and the waist-shaped hole 25. After the fixing bolt 5 is loosened, it is moved to the through hole 24, and the fixing bolt 5 is taken out. If the fixing nut 52 falls into the limiting groove 61 during the dismounting process, the fixing nut 52 is prevented from falling into the pickup. Of course, the anti-falling member 6 also has the same limiting effect as the first limiting plate 26.

[0045] Optionally, as shown in Figure 2 , the pickup further comprises a welding nut 71 and a mounting plate 72. The pickup beam 2 has a hole along the length direction of the pickup beam 2, the welding nut 71 is arranged on the first side surface 21 and aligned with the hole. The mounting plate 72 is arranged on the other side of the pickup beam 2 along the length direction of the pickup beam 2, and the mounting plate 72 has a mounting hole 73. Such an arrangement facilitates the detachable arrangement of the guard on the pickup beam 2. Also, a plurality of pickup beams 2 can be assembled into a pickup.

[0046] Optionally, as shown in Figure 3 、 Figure 12 , the pickup beam 2 comprises a first sub-beam 201 and a second sub-beam 202, and the first sub-beam 201 and the second sub-beam 202 are connected through a transition plate 203. Such an arrangement facilitates the replacement of the first sub-beam 201 and the second sub-beam 202, and reduces the later maintenance cost.

[0047] The utility model discloses a kind of bundlers, including the pickup of any one described above. The bundler can be round bale bundler.
