Description

Technical Field

[0001] This utility model relates to the field of hay bale dismantling technology, and in particular to a hay bale spreading and impurity removal machine. Background Technology

[0002] Hay bales are made from grass, beans, or other herbaceous plants through processes such as cutting, drying, and baling. They are primarily used in animal feed, but also have some industrial and other applications. The processing involves harvesting the grass at the appropriate time to ensure its nutritional value and yield, followed by drying to reduce the moisture content to a suitable level (generally below 17%). The bales are then pressed into square or round rolls using a baler. Hay bales are often used as winter feed for livestock, providing energy, protein, fiber, and other nutrients.

[0003] When it is necessary to remove the hay from the bales, the bales need to be spread out. The traditional method is to manually use a fork to lift and spread the hay. Manual spreading is time-consuming, labor-intensive, and inefficient. In addition, the rolled hay bales often contain impurities such as stones and hard soil clods during the baling process, and it is difficult to remove these impurities directly when the rolled hay bales are spread out into layers.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] Specific embodiments of the hay bale spreading and impurity removal machine provided by this utility model:

[0034] Please see Figure 1-8 The hay bale spreading and impurity removal machine includes a frame 1, a rotary belt 2, a spreading roller 3, a limit roller 4, a conveyor belt 5, and an impurity removal component 7.

[0035] The rotating belt 2 supports the rolled hay bales, and the middle of the rotating belt 2 bends downwards. For example... Figure 2 As shown, the horizontal distance between the rollers on the inner sides of both ends of the rotary belt 2 is less than the length of the rotary belt 2 between the two rollers. The longer length of the middle section of the rotary belt 2 causes the middle section of the rotary belt 2 to bend downwards.

[0036] A support roller is provided on the upper side of the middle of the lower wall of the rotating belt 2 to ensure the stability of the rotating belt 2 and prevent the lower wall of the rotating belt 2 from shaking severely. A recess is formed on the upper wall of the rotating belt 2 to hold rolled hay bales.

[0037] The spreading roller 3 is located on one side of the rotary belt 2, and has annular teeth on the outer ring side to drive the rolled hay bales to spread out. The teeth are evenly arranged along the axial direction of the spreading roller 3. The limiting roller 4 and the spreading roller 3 are located on the upper sides of both ends of the rotary belt 2, respectively.

[0038] The conveyor belt 5 is horizontally positioned below the spreading roller 3 and conveys the spread-out layered grass. The rotary belt 2, spreading roller 3, limit roller 4, and conveyor belt 5 are all mounted on the frame 1; the rotary belt 2 is located on the upper middle part of the conveyor belt 5.

[0039] The rotating belt 2, the spreading roller 3, and the conveyor belt 5 are all driven by motors. Round, rolled bales of straw are placed on the upper side of the rotating belt 2, while the ends of the loose, layered straw are placed on the upper side of the spreading roller 3. As the rotating belt 2 rotates, as... Figure 2 As shown, the upper wall of the rotary belt 2 moves to the right. Due to the blocking roller 4 preventing the rolled hay bales from moving to the right, the rotary belt 2 and the blocking roller 4 cause the rolled hay bales to rotate and release the layered hay. The teeth of the spreading roller 3 cause the layered hay to move to the lower left, conveying the released layered hay and promoting the rotation of the rolled hay bales. The spread layered hay falls on the upper side of the conveyor belt 5, which conveys it to the left. This achieves the spreading of the hay bales.

[0040] The impurity removal component 7 is located at the end of the conveyor belt 5 and has several rotating striking rods 703. The striking rods 703 rotate and strike the layered grass below to separate impurities. The rotation of the striking rods 703 also conveys the layered grass, allowing it to pass smoothly over the impurity removal component 7.

[0041] A comb-shaped receiving frame 6 is provided between the end of the conveyor belt 5 and the impurity removal component 7. The teeth of the receiving frame 6 face away from the conveyor belt 5 and towards the impurity removal component 7. The layered grass conveyed by the conveyor belt 5 moves to the upper side of the impurity removal component 7 through the upper side of the receiving frame 6. The receiving frame 6 plays the role of receiving and transferring, and does not affect the falling of impurities such as stones.

[0042] The impurity removal component 7 includes a U-shaped frame 701, the opening of which faces the conveyor belt 5. Several partition rings 702 are evenly connected to the inner side of the U-shaped frame 701, and the partition rings 702 are parallel to each other. Each tooth of the comb structure of the receiving frame 6 is located on the upper side of each partition ring 702. Each partition ring 702 includes two arc-shaped partitions connected by bolts. The two arc-shaped partitions, one large and one small, are connected to form a ring-shaped partition ring 702. The smaller arc-shaped partition is welded to the U-shaped frame 701. This allows the larger arc-shaped partition to be disassembled, facilitating the installation and assembly of the internal structure.

[0043] The main shaft 704, which passes through the center of the separator ring 702, is rotatably mounted on the U-shaped frame 701. The striking rod 703 is located outside the main shaft 704 and rotates with the main shaft 704. The outer end of the striking rod 703 extends to the outside of the separator ring 702. The main shaft 704 is driven to rotate by a motor, which in turn drives the striking rod 703 to rotate.

[0044] A main shaft 704 is vertically connected to several disks 705; several secondary shafts 706 are evenly arranged around the circumference of the main shaft 704, and the secondary shafts 706 pass through the disks 705 and are rotatably connected to the disks 705; striking rods 703 are evenly connected to the outside of the secondary shafts 706. A ring track 707 is provided on the U-shaped frame 701, and the main shaft 704 passes through the ring track 707; one end of each secondary shaft 706 is connected to a crank 708, and the end of the crank 708 is connected to a guide wheel 709, which extends into the ring track 707; the ring track 707 includes a smoothly connected arc portion 7071 and a straight portion 7072, and the straight portion 7072 is located on the side away from the conveyor belt 5; the distance from each point of the arc portion 7071 to the center of the main shaft 704 is greater than the radius of rotation of the secondary shafts 706, and the distance from the middle of the straight portion 7072 to the center of the main shaft 704 is less than the radius of rotation of the secondary shafts 706.

[0045] The rotation of the main shaft 704 drives the disc 705 to rotate, which in turn drives each secondary shaft 706 to revolve. The secondary shaft 706 drives the striking rod 703 to move. The separating ring 702 supports the layered grass. The striking rod 703 passes through the separating ring 702 and rotates to strike the layered grass, causing stones and other impurities in the layered grass to fall off due to continuous vibration and impact, thus removing stones and other impurities from the grass.

[0046] To prevent the end of the striking rod 703 from penetrating into the layered grass, and thus to prevent the grass from being drawn into the debris removal assembly 7, the end of the secondary shaft 706 is connected to a guide wheel 709 via a crank 708. The guide wheel 709 moves along the circular track 707, as... Figure 5 , Figure 6 , Figure 7 As shown, since the arc portion 7071 of the annular track 707 is larger than the rotation radius of the secondary shaft 706, when the guide wheel 709 at the end of the secondary shaft 706 moves along the arc portion 7071, the striking rod 703 extends out of the separating ring 702, approaching the radial direction. When the guide wheel 709 at the end of the secondary shaft 706 moves to the straight portion 7072, the guide wheel 709 moves within the rotation radius of the secondary shaft 706. The guide wheel 709 causes the secondary shaft 706 to rotate on its own axis while revolving around the central axis via the crank 708, thereby changing the angle of the striking rod 703, which can then retract into the separating ring 702; as Figure 5 As shown, by rotating counterclockwise, the striking rod 703, after contacting the layered grass at the top, can move downwards in a near-vertical posture, almost vertically downwards, and is thus pulled out from the laterally moving layered grass, smoothly separating from it and preventing the grass from being rolled into the debris removal assembly 7. This structure also has the advantage that the rotational retraction of the striking rod 703 can reduce the size of the U-shaped frame 701 and the separating ring 702.

[0047] In order to protect the layered grass and prevent it from being completely broken up, and to allow the layered grass to pass smoothly through the upper side of the debris removal component 7, in this embodiment, the striking rod 703 adopts an elastic striking method; specifically, the striking rod 703 is a torsion spring.

[0048] The torsion spring includes two helical sections, a middle section connecting the two helical sections, and two rods connected to the ends of the helical sections. The rods are used to contact the layered grass. The two rods of the torsion spring are located on both sides of a separator ring 702. When the two rods of the torsion spring strike the layered grass, and encounter greater resistance, the rods can tilt and deform back to the separator ring 702 through the elastic deformation of the helical sections, avoiding damage and protecting the rotating structure inside the impurity removal assembly 7.

[0049] To facilitate the installation and removal of the torsion spring, the secondary shaft 706 is connected to an arc-shaped plate 710 via a fastening bolt 711. The arc-shaped plate 710 passes through the helical portion of the torsion spring. A limiting block 713, which limits the movement of the middle section of the torsion spring, is connected to the arc-shaped plate 710. Specifically, two arc-shaped plates 710 are installed inside the torsion spring, and a bent baffle 712, which limits the movement of the torsion spring, is provided at one end of the arc-shaped plate 710. The fastening bolt 711 passes through the two arc-shaped plates 710 and is connected to the secondary shaft 706. The fastening bolt 711 is located between the two helical portions. The limiting block 713 is located on one of the arc-shaped plates 710. The limiting block 713 acts on the middle section of the torsion spring, keeping the middle section in a fixed position. When the rod is deformed by force, the helical portion deforms.

[0050] To remove the torsion spring, first loosen the fastening bolt 711 to detach it from the countershaft 706. Then, separate the torsion spring from the two arc-shaped plates 710. This structure facilitates the installation and removal of the torsion spring and ensures its stability during operation, preventing it from falling off and reducing damage.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
