Description

Technical Field

[0001] This invention relates to the field of hay baling technology, specifically a livestock hay baling and binding device. Background Technology

[0002] Forage refers to grass or other herbaceous plants used for feeding livestock. Forage needs to be compressed and bundled before transportation.

[0003] Existing technology includes a patent with application number CN202011031863.7, which provides a binding device for baling hay used in livestock farming. The device includes a support frame, a hydraulic rod, and a drive motor. The hydraulic rod is bolted to the upper end of the right side wall of the support frame, and the drive motor is bolted to the upper end of the left side wall of the support frame. A first screw sliding frame is fixedly connected to the upper end of the right side wall of the support frame, and a winding box is fixedly connected to the right side of the lower side wall of the second screw sliding frame. An insert tube is slidably connected to the lower side wall of the second screw sliding frame, and a mounting base is provided directly below the insert tube. A first electric push rod is bolted to the left side wall of the mounting base, and first limiting wheels are rotatably connected at equal intervals to the rear end of the inner side of the support frame. This device achieves the function of binding hay.

[0004] However, the binding device provided by the aforementioned patent still has the following problems during use:

[0005] After being rolled, hay bales tend to expand and loosen. Furthermore, the binding device used in the aforementioned patent clamps and fixes the hay bales between a fixed plate and a turntable using a hydraulic rod during installation. During the fixing process, the hay bales are subjected to axial force, causing them to expand, which reduces their density and increases their space occupancy, making it difficult to transport them. Moreover, the expansion and loosening of the hay bales exacerbates the loosening and falling of the hay on their surface, resulting in resource waste. Summary of the Invention

[0066] The output end of the drive device 22 is connected to the bottom end of the threaded rod 20 for transmission, and the drive device 22 is used to drive the threaded rod 20 to rotate.

[0067] In the lifting assembly 2, the threaded rod 20 is driven to rotate by the drive device 22, which drives the lifting ring 17 to perform lifting and lowering movements, thereby realizing the lifting and lowering movements of the circumferential pressing mechanism 9.

[0068] like Figure 5 and Figures 8-12 As shown, the circumferential pressing mechanism 9 includes a fixed rod 55, a slider 43, a bearing seat 53, and a second motor 52. There are two fixed rods 55, which are located above and below the second mounting plate 45, respectively, and both fixed rods 55 are coaxial with the second mounting plate 45. Multiple discs 54 are fixedly connected between the outer periphery of the fixed rods 55 and the second mounting plate 45. A winding wheel 56 is rotatably mounted between the two fixed rods 55. The bottom end of the winding wheel 56 rotatably passes through the fixed rod 55 below the second mounting plate 45, and a worm gear 58 is fixedly mounted at the bottom end of the winding wheel 56.

[0069] A slider 43 is slidably installed in the second through groove 44. Limiting blocks 50 are fixedly connected to both sides of the slider 43.

[0072] During the compression process, the circumferential pressing mechanism 9 uses motor 2 52 to drive the winding wheel 56 to rotate via worm 59 and worm wheel 58. The winding wheel 56 simultaneously winds multiple ropes 51, causing multiple sliders 43 to slide in the through groove 2 44 towards the winding wheel 56, thereby driving multiple side pressure plates 39 to compress and fix the straw roll around its periphery. The spring 48 allows the sliders 43 to automatically reset.

[0073] like Figure 1 , Figure 3 and Figure 4 As shown, the top pressing mechanism 8 includes a motor 30, a hydraulic rod 33, and two columns 26 fixedly installed on the top surface of the support ring 6. The top ends of the two columns 26 are fixedly connected to a connecting seat 27. The top end of the connecting seat 27 is fixedly connected to a connecting plate 28.

Limiting blocks are fixedly installed at the top and bottom ends of the sliding rods 62. A lifting plate 64 located above the mounting plate 3 is provided between the two sliding rods 62. The two ends of the lifting plate 64 are slidably connected to the periphery of the two sliding rods 62 respectively. A turntable 65 is installed on the top surface of the lifting plate 64. The turntable 65 is used to install the covering film 4. A lead screw 63 is rotatably connected to the top surface of the lifting plate 64. The bottom end of the lead screw 63 passes through the mounting plate 3, and the lead screw 63 is threadedly connected to the mounting plate 3.

[0077] A lifting plate 61 is also provided between the two sliding rods 62 and located below the mounting plate 3.

[0078] The lifting plate 2 64 is provided with a guide component on the side near the support ring 6 for automatically guiding the free end of the covering film 4 to the top surface of the support plate 42.

[0079] In the initial state, the lifting plate 64 is at the lowest point; when the hay roll rotates, the motor 60 in the binding mechanism 5 starts and drives the lead screw 63 to rotate. The lead screw 63 drives the lifting plate 64 to move up and down, so that the covering film 4 completely binds the periphery of the circumferential pressing mechanism 9.

[0080] Existing technologies include a baling device for hay used in livestock farming, such as patent application number CN202011031863.7, which achieves the function of baling hay. However, the baling device provided by the above patent still has the following problems in use: the hay bales expand and loosen after being rolled up. Furthermore, the baling device used in the above patent clamps and fixes the hay bales between the fixed plate and the turntable using a hydraulic rod during installation. During the fixing process, the hay bales receive axial force, causing them to expand, reducing the density of the hay bales, increasing the space occupied by the hay bales, and making it difficult to transport the hay bales. Moreover, after the hay bales expand and loosen, the degree of loosening and falling of hay on the surface of the hay bales is aggravated, resulting in resource waste.

[0081] In this invention:

[0082] In the initial state, the top of the side pressure plate 39 is flush with the top surface of the support plate 42. When in use, the free end of the 4 is first sent to the center of the support plate 42 by the discharge component 7; the feeding conveyor 13 sequentially conveys the straw rolls to the feeding plate 11. When the straw rolls are on the feeding plate 11, the feeding component 12 pushes the straw rolls onto the support plate 42 of the support mechanism, so that the bottom surface of the straw rolls presses the free end of the covering film 4; then the lifting component 2 drives the circumferential pressing. Mechanism 9 rises, causing the top of the side pressure plate 39 to be higher than the top surface of the hay roll. Then, the circumferential pressing mechanism 9 is activated, causing multiple side pressure plates 39 to move simultaneously towards the center of the support plate 42, thereby clamping and fixing the hay roll, achieving the purpose of compressing the hay roll from the outside. Next, the hydraulic rod 33 in the top pressing mechanism 8 is activated, driving the top pressure plate 34 to press the hay roll tightly at the top, achieving compression of the hay roll at the top, while simultaneously pressing down. Multiple spikes 38 on the bottom surface of plate 34 pierce into the hay roll. After the compression operation of the hay roll is completed, motor 30 is started, driving hydraulic rod 33 to rotate, thereby rotating top pressure plate 34. This causes the hay roll, support plate 42, mounting plate 45, and circumferential pressing mechanism 9 to rotate as a whole. Together with binding mechanism 5, the covering film 4 is wrapped and bound around the hay roll. After the wrapping is completed, lifting component 2 drives circumferential pressing mechanism 9 to reset multiple side pressure plates 39 to their initial state, that is, the side pressure plates 39 are pulled out from between the hay roll and the covering film 4. During the process of pulling out the side pressure plates 39, the hay roll will undergo a certain degree of reset expansion under the restraint of the covering film 4, thereby increasing the binding firmness of the covering film 4 on the hay roll. Then, hydraulic rod 33 retracts, causing top pressure plate 34 to separate from hay roll. Then, discharge component 7 pushes the bound hay roll onto discharge conveyor 10 to complete the automatic discharge function. This process is repeated to realize the automatic binding of hay rolls.

[0083] Compared with the prior art, the present invention can compress the straw rolls before binding by setting up the circumferential pressing mechanism 9 and the top pressing mechanism 8, which solves the problem of the straw rolls becoming loose during transportation and feeding, and improves the density of the straw rolls.

[0084] Example 2:

[0085] Please see Figure 5 Based on Embodiment 1, a reinforcing rib is provided on the side of the side pressure plate 39 near the bottom end between it and the top surface of the slider 43, and multiple evenly distributed balls 40 are embedded on both sides of the side pressure plate 39.

[0086] The addition of reinforcing ribs improves the rigidity of the side pressure plate 39 during the compression of the hay roll, thus extending its service life. The ball bearings 40 ensure rolling contact between the side pressure plate 39, the covering film 4, and the hay roll, significantly reducing friction and improving the smoothness of the side pressure plate 39's extraction from the covering film 4 and the hay roll. This also prevents damage to the covering film 4 during extraction. Furthermore, it reduces the lifting and lowering complexity of the lifting assembly 2, further extending the device's service life.

[0087] Example 3:

[0088] Please see Figure 1 and Figure 3 Based on embodiment 2, the discharge assembly 7 includes a second mounting base 23 fixedly installed at the lower part of two columns 26. A second cylinder 25 is fixedly installed on the outer side of the second mounting base 23. The telescopic end of the second cylinder 25 slides through the second mounting base 23, and a push plate 24 is fixedly installed on the telescopic end of the second cylinder 25.

[0089] The feeding assembly 12 includes a mounting base 21. The mounting base 21 is fixedly mounted on the top surface of the feeding plate 11. A cylinder 36 is fixedly mounted on the outer side surface of the mounting base 21. The telescopic end of the cylinder 36 slides through the mounting base 21, and a push plate 37 is fixedly mounted on the telescopic end of the cylinder 36.

[0090] The axis of cylinder 36 intersects perpendicularly with the axis of cylinder 25.

[0091] In the feeding assembly 12, cylinder 36 extends and pushes the straw roll on the feeding plate 11 onto the support plate 42 via pusher plate 37; in the discharging assembly 7, cylinder 25 drives pusher plate 24 to push the bundled straw roll onto the discharging conveyor 10; compared with the prior art, the present invention realizes the automatic feeding and self-discharging functions of straw rolls through the coordinated arrangement of discharging conveyor 10, feeding conveyor 13, feeding plate 11, feeding assembly 12 and discharging assembly 7, thereby improving the automation level of the device.

[0092] Example 4:

[0093] Please see Figures 13-15 Based on embodiment 3, the guiding assembly includes a guide plate 68 fixedly installed on the outer side of the lifting plate 64. The end of the guide plate 68 away from the lifting plate 64 points to the center of the support plate 42. A guide plate 67 is slidably inserted at the end of the guide plate 68 away from the lifting plate 64. A fixing block 71 is fixedly connected to the bottom surface of the guide plate 67 at the end away from the guide plate 68. An electric push rod 70 is fixedly installed on the bottom surface of the guide plate 68. The telescopic end of the electric push rod 70 is fixedly connected to the fixing block 71.

[0094] Multiple guide rollers 69 are arranged in an array along the length of both sides of the top surface of the guide plate 68;

[0095] A housing 73 is fixedly installed on the top surface of the guide plate 2 67 at the end away from the guide plate 1 68. Multiple through holes 74 are evenly opened on the top surface of the housing 73. A blower 72 and a suction fan 77 that communicate with the inside are respectively installed on both sides of the housing 73. The height of the top surface of the housing 73 is lower than the height of the top surface of the turntable 65.

[0096] A servo motor 75 is fixedly installed on the side of the housing 73 away from the guide plate 68, and a cutter 76 is installed at the output end of the servo motor 75.

[0097] The free end of the covering film 4 passes between multiple sets of guide rollers 69. Before binding, the free end of the covering film 4 is placed on the top surface of the box 73. The suction fan 77 is started and adsorbs the free end of the covering film 4 onto the top surface of the box 73 through multiple through holes 74. Then the electric push rod 70 extends and drives the second guide plate 67 to extend, so that the box 73 is located above the circular position of the support plate 42. At the same time, the turntable 65 rotates, so that the free end of the covering film 4 remains adsorbed on the top surface of the box 73 during the extension of the second guide plate 67.

[0098] Next, turn off the suction fan 77 and start the blower 72, so that air is expelled from the multiple through holes 74, causing the free end of the covering film 4 to separate from the top surface of the box 73. The electric push rod 70 drives the guide plate 67 to retract and reset, and the free end of the covering film 4 will fall to the center of the top surface of the support plate 42. This allows the straw roll to press the free end of the covering film 4 against the bottom surface when it is guided to the top surface of the support plate 42, thus fixing the free end of the covering film 4 and ensuring that the covering film 4 can be bound to the periphery of the pressing mechanism 9 as the straw roll rotates.

[0099] After binding is completed, the servo motor 75 is activated to drive the cutter 76 to rotate one revolution, cutting the covering film 4 to form a new free end.

[0100] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
