Description

Technical Field

[0001] The utility model relates to the technical field of a bale picker, in particular to a bale guiding device used for a bale picker to pick up net bag bales. Background Art

[0002] The square bale picker and stacker is also called bale picker, which is mainly used to pick up small square bales. Figure 1 As shown, the bale picker is connected to the tractor through a traction head. The tractor drives the picker to move. The picker lifts the bales on the ground to the first-level platform. After the first-level platform is filled with 3 to 4 bales, it is turned over and unloaded to the second-level platform. After the second-level platform reaches the required number of bales, it is turned over again and unloaded to the loading platform. Finally, the tractor drives the picker filled with bales to the user's designated location for stacking and unloading for storage. The bale picker can complete all processes such as picking, loading, transportation and stacking, thereby replacing the heavy manual picking and stacking work.

[0003] Straw bales include two-line bales, three-line bales and net bag bales. Figure 2 As shown in the figure, the grass in three-rope or two-rope bales is pressed into sheets, placed horizontally, tied with ropes vertically, and has a high density. Figure 3 As shown, the net bag is mainly baled with a film belt horizontally, and the grass on the two end faces in the longitudinal direction is not wrapped and exposed, and the grass is short and broken. When the existing bale picker picks up two-rope bales or three-rope bales: the bale is placed flat on the ground, and the picker moves forward in alignment with the bale; when the bale enters the picker and the front end touches the trigger, the two ends are lifted and start to move upward, and the lifting fork in the picker chain cuts into the grass on the end face of the bale and lifts the bale; after lifting to a certain height, the bale flips sideways onto the first-level platform. Since the three-rope or two-rope bales are placed horizontally and tightened longitudinally, the lifting fork is not easy to fall off when lifting the bale, and the bale can be smoothly lifted and placed on the first-level platform for the next movement.

[0004] However, when the existing bale picker picks up the net bag bale, the bottom of the bale is on the ground, and the lifting fork in the lifting chain of the picker cuts into the end of the bale instead of the bottom of the bale. Since the end of the net bag bale is not wrapped with a film, and the grass in the net bag bale is generally straw or wheat straw and is relatively broken, the lifting fork can easily break the grass on the end of the net bag, and the lifting fork has no support point and is not easy to lift the net bag bale, so the bale cannot be smoothly tipped onto the primary platform. The existing bale picker has the following defects and deficiencies when picking up the net bag bale: 1. The quality of the bale is easily damaged. The grass on the end is easily messed up during the process of the picker lifting the bale, resulting in a loose bag phenomenon; 2. The work efficiency is low. When the picker picks up the net bag bale, the tractor walking speed and the lifting chain running speed are relatively slow, otherwise the lifting chain of the picker cannot smoothly flip the bale onto the primary platform. Even so, the net bag bale cannot be flipped onto the primary platform from time to time. When this happens, manual assistance is required to turn the bale onto the primary platform, which greatly reduces the work efficiency and requires manual assistance to complete the bale picking work.

[0037] The front end of the rear support plate assembly 1 is provided with a slide plate 12, which is a rectangular plate, and three slide holes 13 are evenly distributed in the slide plate 12. The rear end of the front support plate assembly 2 is provided with a slide groove 21 corresponding to the slide plate 12, and a slide column 22 corresponding to the slide hole 13 is provided in the slide groove 21. The slide plate 12 is inserted into the slide groove 21, and the slide column 22 is inserted into the slide hole. It also includes a compression spring 23, which is installed on the slide column 22 and is located at the front end of the slide column 22. The compression spring 23 limits the distance between the rear support plate assembly 1 and the front support plate assembly 2, and ensures that the front support plate assembly 2 moves stably when subjected to external force.

[0038] Bosses 14 are provided on both sides of the end of the slide plate 12, and the positioning blocks 5 are fixedly connected to both sides of the rear end of the front support plate assembly 1. The positioning blocks 5 clamp the bosses 14 to limit the separation of the rear support plate assembly 1 from the front support plate assembly 2 and to limit the rear support plate assembly 1 from being removed from the front support plate assembly 2.

[0039] The rear support plate assembly 1 and the front support plate assembly 2 are used to hold up the straw bale. The rear support plate assembly 1 and the front support plate assembly 2 are slidably connected. When subjected to external force, the rear support plate assembly 1 and the front support plate assembly 2 can generate relative displacement to unload the force.

[0040] The main body of the front support plate assembly 2 is a rectangular plate, and the front support plate assembly 2 is provided with two rectangular through holes for installing the ratchet mechanism 3 .

[0041] The ratchet mechanism 3 includes a rotating shaft 31, a large ratchet 32, a small ratchet 33, a pawl 34, a pawl fixing seat 35 and a tension spring 36. The two ends of the rotating shaft 31 are hinged to the front support plate assembly 2 through bearings. The large ratchet 32 ​​and the small ratchet 33 are an integrated structure.

The guide plate 4 and the connecting block 7 are connected by bolts, and then the guide plate 4 is detachably installed at the front end of the front support plate assembly 2. The guide plate 4 is used to cut into the bottom of the bale and guide the bale onto the front support plate assembly 2. The limit block 6 is fixed to the pickup body and is located at the bottom. The function of the limit block 6 is to limit the lowest position of the guide plate 4 to avoid cutting too deep into the ground and causing damage to the bale guide device.

[0043] The working principle and working process of the utility model are as follows:

[0044] The tractor moves forward and aligns the pickup with the bale. When the bale contacts the trigger, the lifting chain 8 starts to move upward. Since the bale guide device is at a certain angle to the horizontal plane, the lifting fork 9 lifts the bale from the bottom. The function of the ratchet mechanism 3 is to ensure that the bale can only move forward and cannot slide backward, thereby ensuring that the bale will not move backward when the lifting fork 9 lifts the net bag bale 10, and the lifting reliability is guaranteed.

[0045] The rear support plate assembly 1 and the front support plate assembly 2 can produce a relative movement of 0 to 50 mm. When the wear-resistant guide plate 4 contacts the ground and is subjected to the reaction force of objects on the ground, the relative movement between the rear support plate assembly 1 and the front support plate assembly 2 can unload the force, ensuring that the bundle guiding device will not be damaged.

[0046] The function of the hinge 11 is to rotate in real time with the continuous change of the ground height, ensuring that the wear-resistant guide plate 4 is always in contact with the ground, so that the net bag straw bale 10 can smoothly enter the support plate, while preventing the bale guide device from being damaged by the ground force.

[0047] The utility model makes the net bag straw bale 10 on the ground contact the lifting chain 8 at a certain angle, and when the lifting chain moves upward, the lifting fork 9 lifts the bottom of the straw bale, thereby lifting the straw bale and turning it sideways onto the first-level platform.

[0048] The utility model enables the lifting fork 9 in the lifting chain 8 of the picker to cut into the bottom surface of the net bag straw bale 10, and the utility model can provide a support point to assist the lifting fork 9 to lift the net bag straw bale 10, and smoothly tip the net bag straw bale 10 onto the first-level platform. The utility model enables the bale picker to pick up the net bag straw bale smoothly, avoids the damage of the net bag straw bale 10, ensures the quality of the net bag straw bale 10, and improves the efficiency of the picking operation.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
