Description

Technical Field

[0001] This utility model relates to the field of bale-loosening machines, and in particular to a bale-loosening machine for hay bales. Background Technology

[0002] Loosening hay bales refers to the process of breaking down and loosening baled hay bales (round or square), mainly used for livestock feeding, straw return to the field, and organic fertilizer production. To improve efficiency, a mechanical bale-breaking machine has been introduced to the market, which uses rotating blades or toothed rollers to chop the hay bales, making it more efficient than manual chopping.

[0003] For bale-loosening machines that process round bales, both ends of the machine are equipped with limit rollers to prevent bale deviation, and one side has a toothed roller. The limit rollers limit the bales, and the toothed roller loosens them. However, placing the bales requires either multiple people lifting them or using a hoist. Lifting them above the limit rollers is laborious; hoisting requires additional equipment, and assembling the bales with the hoist hook before hoisting also takes time.

[0004] Therefore, this utility model provides a hay bale unpacking machine to improve the convenience of hay bale placement. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a hay bale unpacking machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hay bale unloading machine includes a frame, with toothed rollers at both the input and output ends of the frame. A lifting mechanism for supporting hay bales is provided between the two toothed rollers. The toothed roller at the input end can move around the lifting mechanism. A feeding plate is rotatably installed at the input end of the frame. The feeding plate tilts up as the toothed roller descends to form a slope.

[0008] Preferably, pry bars are rotatably installed on both sides of the input end of the frame below the toothed roller, with one end of the pry bar located in the middle of the toothed roller's stroke and the other end located on the bottom wall of the feeding plate.

[0009] Preferably, a tension spring is provided between the feeding plate and the frame.

[0010] Preferably, the two pry bars are located at the bottom wall of the loading plate and are connected to a lifting shaft.

[0011] Preferably, it also includes a feed plate fixed to the output end of the frame.

[0012] Preferably, the feed plate and the unfeed plate are provided with notches on opposite sides that correspond one-to-one with the toothed rings of the toothed roller.

[0013] Preferably, the lifting mechanism is a belt type.

[0014] Preferably, the inner wall of the frame is provided with an annular guide groove, the upper side of the guide groove is recessed, and the belt side is provided with a plug embedded in the guide groove.

[0015] Preferably, the lifting mechanism is a roller type.

[0016] Compared with the prior art, this utility model provides a hay bale unpacking machine, which has the following beneficial effects:

[0017] 1. In this invention, during feeding, the support, carrying the input-end toothed roller, descends along the slide, thus concealing the input-end toothed roller below the edge of the lifting mechanism. Simultaneously, the support descends, pressing down on the pry bar, which then lifts against the feeding plate, forming a ramp. Pushing the bales along the ramp is much easier than lifting them; moreover, the concealed input-end toothed roller does not obstruct or interfere with the pushing of the bales.

[0018] 2. In this utility model, the geared motor drives the lifting mechanism to rotate, thereby guiding the bale to rotate; at the same time, through chain transmission, it drives two sets of toothed rollers to rotate. The outer hook of the toothed roller at the output end pulls the straw out from the feed plate, and the inner hook of the toothed roller at the input end pulls the bale to assist the bale to rotate, thereby realizing the loose bale operation.

[0019] 3. In this utility model, as the diameter of the hay bale gradually decreases, the telescopic rod extends and the rocker arm deflects again, causing the lifting mechanism to lift the input end toothed roller around the slide rail, thereby moving the input end toothed roller above the lifting mechanism, so as to prolong the contact time between the input end toothed roller and the hay bale, and thus prolong the effect of assisting the hay bale to rotate.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0031] Example 1: To improve the convenience of placing round hay bales, this example provides a hay bale unpacking machine, including a frame 1. The frame 1 is assembled by welding or bolting two steel plates with multiple steel pipes.

[0032] The frame 1 is equipped with a lifting mechanism 8 for placing and supporting the bales of straw.

[0033] In this embodiment, the lifting mechanism 8 has two forms:

[0034] The first type is the roller type: it includes multiple rollers rotatably mounted on the frame 1, which are connected by a belt drive and rotate synchronously and in the same direction. The multiple rollers combine to form a sunken arc shape, which constitutes a placement cavity for holding the bales. The sunken arc shape helps to position the bales and prevents them from easily deviating.

[0035] The second type is the belt type: it includes two belt rollers and a belt fitted on the two belt rollers. The two belt rollers are connected by a chain drive and rotate synchronously and in the same direction. In order to form a sinking bin for placing bales, an annular guide groove 9 is provided on the inner wall of the frame 1. The upper part of the guide groove 9 sinks down, and several insert rods are provided at intervals on the side of the belt and embedded in the guide groove 9. Through the guidance of the insert rods and the guide groove 9, the upper part of the belt sinks down.

[0036] Both of these methods can form the lifting mechanism 8 of the sinkhole structure, used to lift the hay bales and help stabilize them, while also guiding the rotation of the hay bales caused by the pull of the toothed roller 2. The attached diagram shows the second type of belt-type lifting mechanism 8, and the following description also uses the belt-type lifting mechanism 8 as an example. In the attached diagram, the rotational power of the belt-type lifting mechanism 8 is provided by the geared motor 10.

[0037] The frame 1 is located at the two ends of the lifting mechanism 8, which are the input end and the output end respectively. The input end is the end for feeding the bales, and the output end is the end for feeding the straw after the bales have been unpacked.

[0038] Both the input and output ends of the frame 1 are equipped with toothed rollers 2, and multiple sets of serrated rings are fixed on the toothed rollers 2. The toothed rollers 2 at the output end are rotatably mounted on the frame 1 and are connected to the belt rollers at the output end via chain drive, rotating synchronously and in the same direction. Both sides of the input end of the frame 1 are provided with arc-shaped slide rails 5, within which support seats 4 are slidably mounted. Bearings are embedded in the support seats 4, and the two ends of the toothed rollers 2 at the input end are respectively embedded in the inner rings of the two bearings, thus allowing the toothed rollers 2 at the input end to both rotate on their own axis and move around the slide rails 5. The slide rails 5 are coaxially arranged with the belt rollers at the input end, allowing the toothed rollers 2 to move around the axis of the belt rollers at the input end. Both sides of the frame 1 are rotatably mounted with rocker arms 3. The rotatable end of the rocker arm 3 is sleeved on the shaft head of the input end roller. The connecting end of the rocker arm 3 is rotatably connected to the support 4. A telescopic rod 6 is rotatably mounted on the frame 1. The telescopic rod 6 can be any one of a hydraulic rod, a pneumatic rod, or an electric telescopic rod 6. The extended end of the telescopic rod 6 is rotatably connected to the non-end part of the rocker arm 3. The telescopic rod 6 is used as a driving component to drive the input end toothed roller 2 to move and remain stable after moving.

[0039] The center of the slide rail 5 is flush with the axis of the output toothed roller 2. The slide rail 5 has a horizontal opening in the middle to facilitate the insertion and installation of shaft components.

[0040] The output end of the frame 1 is provided with a feed plate 12, which is used to guide the scattered grass to be transported outward.

[0041] The input end of the frame 1 is rotatably mounted with a feeding plate 11. Both sides of the input end of the frame 1 are rotatably mounted with pry bars 7 below the toothed roller 2. One end of the pry bar 7 is located in the middle of the stroke of the toothed roller 2 and abuts against the support 4, and the other end is located on the bottom wall of the feeding plate 11.

[0042] Based on the above technical solution:

[0043] After the equipment is assembled, the toothed rollers 2 at both ends are on the same plane. At this time, the input toothed roller 2 is located in the center of the slide 5. One end of the pry bar 7 is against the bottom wall of the support 4 and the other end is against the bottom wall of the feeding plate 11. The unloading plate 12 hangs down naturally.

[0044] During loading, to facilitate the insertion of the bales, the telescopic rod 6 retracts, causing the rocker arm 3 to deflect. This allows the support 4, carrying the input-end toothed roller 2, to descend around the slide rail 5, thus concealing the input-end toothed roller 2 below the side of the lifting mechanism 8. Simultaneously, as the support 4 descends, the pry bar 7 is pressed down, causing it to lift against the loading plate 11, thus forming a ramp. Pushing the bales along the ramp is easier than lifting them; moreover, the concealed input-end toothed roller 2 does not obstruct or interfere with the pushing of the bales.

[0045] When the bales are loosened, the telescopic rod 6 extends, the input toothed roller 2 moves to the assembled state, and the feeding plate 11 droops under its own weight. The geared motor 10 drives the lifting mechanism 8 to rotate, thereby guiding the bales to rotate; at the same time, through chain drive, it drives the two sets of toothed rollers 2 to rotate, and pulls the straw through multiple sets of serrated hooks on the toothed rollers 2: see attached... Figure 7 As shown, the outer hook of the toothed roller 2 at the output end pulls the straw from the feed plate 12, and the inner hook of the toothed roller 2 at the input end pulls the straw bale to assist the bale's rotation, thereby realizing the loose bale operation.

[0046] As the diameter of the hay bale gradually decreases, the telescopic rod 6 extends and the rocker arm 3 deflects again, causing the lifting mechanism to lift the input end toothed roller 2 around the slide rail 5, thereby moving the input end toothed roller 2 above the lifting mechanism 8, so as to prolong the contact time between the input end toothed roller 2 and the hay bale, and thus prolong the effect of assisting the hay bale to rotate.

[0047] In this embodiment, a tension spring is provided between the feeding plate 11 and the frame 1 (one end of the tension spring is hooked to the side of the frame 1, and the other end is hooked to the bottom wall of the feeding plate 11), which is not shown in the attached drawings. The tension spring always provides a pulling force to the feeding plate 11, so that when the pry bar 7 does not apply an upward force to the feeding plate 11, the feeding plate 11 always remains in a downward state under the pulling action of the tension spring, avoiding the feeding plate 11 from shaking continuously with movement or vibration, thus reducing knocking noise and preventing the feeding plate 11 from vibrating and potentially injuring nearby personnel.

[0048] In this embodiment, the upper plate 11 and the lower plate 12 are each provided with notches on opposite sides that correspond one-to-one with the serrated rings of the toothed roller 2. This makes the toothed roller 2 more tightly installed.

[0049] In this embodiment, the lower side wall of the rocker arm 3 is provided with an extension, which facilitates the adjustment of the installation and extension state of the telescopic rod 6, and also moves the pry bar 7 downward, shortening its size to avoid installation interference issues during assembly due to its excessive length. After the extension is provided, the upward-curved end of the pry bar 7 no longer abuts against the support 4 at the middle of the slide rail 5, but rather against the extension.

[0050] In this embodiment, the ends of the two pry bars 7 located below the feeding plate 11 are connected to a lifting shaft, which is a rubber roller, so that the feeding plate 11 has more force points and the upward tilting is more stable.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
