Description

Technical Field

[0001] This utility model relates to the technical field of agricultural production equipment, specifically to a mobile crop straw picking and baling machine. Background Technology

[0002] In agriculture, the effective collection and treatment of crop straw and other waste can prevent it from being discarded or burned indiscriminately in fields, reducing environmental pollution and helping to maintain the cleanliness of farmland and the stability of the ecological environment. Baled straw or hay is easy to transport and store, and can be used as livestock feed, papermaking raw materials, and biomass energy feedstock, thus realizing the resource utilization of agricultural waste.

[0003] Different types of straw have different physical properties. For example, corn stalks are thicker and more resilient, rice stalks are softer and easier to tangle, and wheat stalks are dry and easily broken. These properties affect the flow performance of the straw in the feed hopper. Thick, resilient straw may get stuck in the feed hopper because it is not easy to bend, while soft, easily tangled straw is prone to tangling together and causing blockages.

[0004] In addition, when the straw is damp, sticks together, or contains leaves, weeds and other debris, the straw's own weight and the tension of the conveyor belt are not enough to ensure that the straw passes through the feed hopper smoothly. This causes the straw to accumulate and block the feed hopper, requiring the equipment to be stopped frequently for cleaning, which reduces the efficiency of operation. Utility Model Content

[0005] This utility model provides a mobile crop straw picking and baling machine, which can solve the problem in the existing technology that it is difficult to ensure that the straw passes through the feed hopper smoothly by relying solely on the weight of the straw itself and the tension of the conveyor belt, resulting in the straw accumulating and blocking in the feed hopper.

[0006] A mobile crop straw picking and baling machine includes a support frame, tires, a material conveying mechanism, a baling mechanism, and a traction frame. Two sets of tires are symmetrically arranged on both sides of the support frame. The material conveying mechanism is located inside the support frame, the baling mechanism is located at one end of the support frame, and the traction frame is fixedly located at the other end of the support frame. The material conveying mechanism includes a conveyor belt, a feed hopper, a wall panel, and a vibration assembly for striking the wall panel to generate vibration. The conveyor belt is horizontally positioned inside the support frame, with one end located within the baling mechanism. The feed hopper is fixedly connected to the support frame and located above the conveyor belt. Several inclined, horizontally arranged sliding holes are provided on the side of the feed hopper. Several sliding rods that slidably engage with the corresponding sliding holes are fixedly provided on one side of the wall panel.

[0007] According to one embodiment of the present invention, the material conveying mechanism further includes a limiting ring. One end of the slide rod is fixedly connected to the wall panel, and the limiting ring is coaxially fixedly connected to the slide rod and located at the other end of the slide rod. The material conveying mechanism also includes a spring, which is wound around the side of the slide rod. One end of the spring abuts against the feed hopper, and the other end of the spring abuts against the limiting ring.

[0008] According to one embodiment of the present invention, the vibration assembly includes a rotating shaft and a cam. A through groove is provided on the side of the feed hopper. The rotating shaft is horizontally fixedly connected to the cam. The rotating shaft is rotatably connected to the feed hopper and is located at the opening of the through groove. The vibration assembly also includes a drive motor, which is fixedly connected to the feed hopper. The output end of the drive motor is coaxially fixedly connected to the rotating shaft.

[0009] According to one embodiment of this utility model, the baling mechanism includes a housing and baling rollers. The housing is fixedly connected to a support frame. Several baling rollers are arranged and rotatably mounted horizontally inside the housing. The baling mechanism also includes sprockets and chains. Several sprockets are arranged and coaxially fixedly connected to corresponding baling rollers. The chains are arranged between the sprockets. The several baling rollers are arranged in a circumferential array at equal intervals.

[0010] According to one embodiment of the present invention, a plurality of electric push rods arranged in a matrix are fixedly provided at the bottom of the support frame.

[0011] According to one embodiment of the present invention, a plurality of baffles arranged in a matrix are fixedly provided on the surface of the conveyor belt.

[0012] The advantages of this utility model compared to the prior art are:

[0013] By coordinating the vibration components with the wall panels, sliding rods, and sliding holes in the material conveying mechanism, the problem of straw accumulation and blockage in the feed hopper is effectively solved. The independent vibration of the wall panels not only promotes the straw to slide fully onto the conveyor belt, ensuring smooth feeding, but also avoids damage to other components of the feed hopper caused by vibration, reducing equipment downtime due to poor feeding and improving the continuity and stability of operation.

[0023] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0024] like Figures 1 to 5 As shown, a mobile crop straw picking and baling machine includes a support frame 1, tires 2, a material conveying mechanism 3, a baling mechanism 4, and a traction frame 5. Two sets of tires 2 are symmetrically arranged on both sides of the support frame 1. The material conveying mechanism 3 is located inside the support frame 1. The baling mechanism 4 is located at one end of the support frame 1. The traction frame 5 is fixedly located at the other end of the support frame 1. The material conveying mechanism 3 includes a conveyor belt 6, a feed hopper 7, a wall panel 8, and a vibration component 9 for striking the wall panel 8 to generate vibration. The conveyor belt 6 is horizontally arranged inside the support frame 1, with one end of the conveyor belt 6 located inside the baling mechanism 4. The feed hopper 7 is fixedly connected to the support frame 1 and located above the conveyor belt 6. Several inclined and horizontally arranged sliding holes 10 are provided on the side of the feed hopper 7. Several sliding rods 11 are fixedly provided on one side of the wall panel 8 and slidably connected to the corresponding sliding holes 10.

[0025] When using this mobile crop straw picking and baling machine, first connect the towing frame 5 to a towing device such as a four-wheel tractor, and use the power of the towing device to move the baler to the designated location in the farmland where the straw needs to be picked up. Then, a loader or other grabbing equipment puts the crop straw into the feed hopper 7.

[0026] After the straw enters the feed hopper 7, some of it falls directly onto the conveyor belt 6, which is horizontally set within the support frame 1, due to its own gravity; the rest tends to accumulate on the inner wall of the feed hopper 7. At this time, the vibration component 9 is activated and strikes the wall panel 8. The wall panel 8 vibrates independently due to the sliding engagement between the slide rod 11 and the sliding hole 10 on the side of the feed hopper 7, preventing the vibration from being transmitted to the overall structure of the feed hopper 7 and reducing the impact on the stability of the feed hopper 7 and the entire machine. At the same time, under the vibration of the wall panel 8, the originally accumulated straw loosens and slides onto the conveyor belt 6.

[0027] Driven by the power system, the conveyor belt 6 operates continuously, transporting the straw falling on it to one end without interruption until the straw is fed into the baling mechanism 4 located at one end of the support frame 1. The baling mechanism 4 compresses and bundles the transported straw, turning the loose straw into neat bales, thus completing the entire process of picking up and baling crop straw.

[0028] The cooperation between the vibration component 9 in the material conveying mechanism 3 and the wall plate 8, slide rod 11, and sliding hole 10 effectively solves the problem of straw accumulation and blockage in the feed hopper 7. The independent vibration of the wall plate 8 not only promotes the straw to slide fully onto the conveyor belt 6, ensuring smooth feeding, but also avoids damage to other components of the feed hopper 7 caused by vibration, reducing equipment downtime due to poor feeding and improving the continuity and stability of operation.

[0029] In some specific embodiments, the material conveying mechanism 3 further includes a limiting ring 12. One end of the slide rod 11 is fixedly connected to the wall panel 8, and the limiting ring 12 is coaxially fixedly connected to the slide rod 11 and located at the other end of the slide rod 11. The material conveying mechanism 3 also includes a spring 13, which is wound around the side of the slide rod 11. One end of the spring 13 abuts against the feed hopper 7, and the other end of the spring 13 abuts against the limiting ring 12.

[0030] When the vibration component 9 strikes the wall panel 8, the wall panel 8 slides under the cooperation of the slide rod 11 and the sliding hole 10. Since the limit ring 12 is coaxially fixedly connected to the slide rod 11, and the spring 13 is wrapped around the side of the slide rod 11, with one end abutting against the feed hopper 7 and the other end abutting against the limit ring 12, the wall panel 8 will compress or stretch the spring 13 when it slides. The elastic force of the spring 13 will cause the wall panel 8 to automatically reset after the vibration ends. At the same time, during the vibration of the wall panel 8, the spring 13 plays a role in buffering and limiting, restricting the sliding range of the wall panel 8, ensuring that the vibration amplitude and frequency of the wall panel 8 are within a reasonable range, maintaining a stable vibration effect, and continuously promoting the straw to slide onto the conveyor belt 6.

[0031] The combination of spring 13 and limiting ring 12 ensures that the wall plate 8 remains stable during vibration, preventing excessive or insufficient vibration amplitude from affecting the straw sliding effect. Stable vibration allows the straw to slide more evenly and efficiently from the inner wall of the feed hopper 7 to the conveyor belt 6, further improving the smoothness of feeding and reducing the risk of blockage.

[0032] The buffering effect of spring 13 can effectively reduce the impact force of vibration assembly 9 on wall plate 8 and feed hopper 7, reduce the wear and damage of components caused by frequent vibration, extend the service life of wall plate 8, slide rod 11, slide hole 10 and other related components, and reduce the cost and frequency of equipment maintenance and component replacement.

[0033] The limiting ring 12 restricts the sliding range of the slide bar 11, preventing the wall panel 8 from deviating from the normal operating trajectory during vibration, enhancing the reliability and stability of the entire material conveying mechanism 3 structure, and ensuring that the material conveying mechanism 3 can always function normally during long-term operation of the baler.

[0034] In some specific embodiments, the vibration assembly 9 includes a rotating shaft 14 and a cam 15. A through groove 16 is provided on the side of the feed hopper 7. The rotating shaft 14 is horizontally fixedly connected to the cam 15. The rotating shaft 14 is rotatably connected to the feed hopper 7 and is located at the opening of the through groove 16. The vibration assembly 9 also includes a drive motor 17, which is fixedly connected to the feed hopper 7. The output end of the drive motor 17 is coaxially fixedly connected to the rotating shaft 14.

[0035] After the drive motor 17 starts, its output end drives the cam 15, which is coaxially fixedly connected to the rotating shaft 14, to rotate. Since the rotating shaft 14 is rotatably engaged with the feed hopper 7 and located at the opening of the through groove 16, as the cam 15 rotates, its protruding part periodically presses against the wall plate 8, causing the wall plate 8 to vibrate. When the protruding part of the cam 15 leaves the wall plate 8, the wall plate 8 returns to its original position under the action of the spring 13. This cycle repeats, achieving continuous vibration of the wall plate 8, thereby loosening the straw accumulated in the feed hopper 7.

[0036] Cam 15 can convert rotational motion into reciprocating vibration of wall plate 8. By rationally designing the shape and size of cam 15, the frequency and amplitude of vibration of wall plate 8 can be precisely controlled, providing a more effective vibration driving force for straw to slide down. Compared with other vibration methods, it can solve the problem of straw accumulation more efficiently.

[0037] In some specific embodiments, the baling mechanism 4 includes a housing 18 and baling rollers 19. The housing 18 is fixedly connected to the support frame 1. Several baling rollers 19 are arranged horizontally and rotatably inside the housing 18. The baling mechanism 4 also includes sprockets 20 and chains 21. Several sprockets 20 are arranged and coaxially fixedly connected to corresponding baling rollers 19. The chains 21 are arranged between the sprockets 20. The several baling rollers 19 are arranged in a circumferential array at equal intervals.

[0038] It should be specifically noted that the rotation of the baling rollers 19 can be driven by the same power source as the conveyor belt 6. For example, a rotary motor can be fixedly installed on the side of the support frame 1, and a driving roller and a driven roller can be rotatably installed at both ends of the inner side of the support frame 1. The conveyor belt 6 is positioned between the driving roller and the driven roller. The output end of the rotary motor is coaxially and fixedly connected to the driving roller. At the same time, a sprocket 20 is coaxially and fixedly connected to the output end of the rotary motor. Since the chain 21 is positioned between each sprocket 20, the rotating sprocket 20 transmits power to the other sprockets 20 through the chain 21, thereby driving all the baling rollers 19 to rotate synchronously. Several baling rollers 19 arranged in a circumferential array at equal intervals work together to compress the incoming straw. As the straw is continuously fed in, the rotation of the baling rollers 19 gradually compresses the straw into bales with a certain shape and density, finally completing the baling process.

[0039] The drive mechanism of sprocket 20 and chain 21 ensures that all baling rollers 19 rotate at the same speed and in the same direction, guaranteeing the uniformity and stability of straw compression. This avoids problems such as irregular bale shape and uneven density caused by inconsistent rotation of the baling rollers 19, improving the quality and uniformity of the bales and facilitating subsequent transportation and storage.

[0040] In some specific implementations, a plurality of electrically driven push rods 22 arranged in a matrix are fixedly installed at the bottom of the support frame 1. When the baler operates in farmland with different terrains, or when it is necessary to adjust the relative height of the baler with the traction device and the gripping device, the electrically driven push rods 22 at the bottom of the support frame 1 are controlled. The electrically driven push rods 22 change their length through extension and retraction, thereby adjusting the height of the support frame 1. The multiple electrically driven push rods 22 arranged in a matrix work together to ensure that the support frame 1 rises and falls smoothly, meeting the height requirements of the baler in different operating scenarios.

[0041] In some specific embodiments, a plurality of baffles 23 are fixedly arranged in a matrix on the surface of the conveyor belt 6. During the operation of the conveyor belt 6, the fixed baffles 23 move together with the conveyor belt 6. When straw falls onto the conveyor belt 6, the baffles 23 prevent the straw from sliding or rolling on the conveyor belt 6, so that the straw is more stably conveyed to the baling mechanism 4 along the conveyor belt 6 under the push of the baffles 23.

[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
