Description

Technical Field

[0001] This invention relates to the field of automatic harvesting devices, and more particularly to an automatic harvesting device for processing elephant grass stems. Background Technology

[0002] In agricultural production, traditional manual harvesting has always held an important position. However, with the advancement of large-scale and intensive agricultural development, this labor-intensive operation mode has gradually exposed many drawbacks. On the one hand, manual harvesting is extremely labor-intensive, requiring workers to bend over for long periods of time, which is not only inefficient but also prone to physical fatigue and injury. On the other hand, against the backdrop of continuously rising labor costs, the high cost of labor has seriously affected the economic benefits of agricultural production.

[0003] While some existing mechanized harvesting equipment has alleviated the above problems to some extent, it still has many shortcomings. For example, the harvesting mechanism of some equipment is not designed reasonably, making it difficult to effectively guide the stalks to the designated position for cutting and conveying during the harvesting process.

[0004] A search revealed Chinese patent application CN202320774306.7, which discloses an adjustable-spacing hand-held soybean harvester. The harvester includes a handcart, with a harvester body fixedly connected to its front end. Fixed shafts are fixedly connected to both sides of the harvester body, and harvesting teeth are fixedly connected to the center of the harvester body. Identical harvesting teeth are threaded to both sides of the harvesting teeth via a first threaded rod. The two side harvesting teeth are slidably connected to the surface of the harvester body, and a drive device is installed inside the central harvesting tooth. The soybean harvester in the aforementioned document has the following shortcomings: although it can meet the cutting requirements, it cannot effectively directionally transport the harvested material.

[0027] The roller frame has a rotatable roller mounted on it. The roller surface is provided with multiple sets of arc-shaped blades, with two arc-shaped blades in each set arranged symmetrically. A transverse sliding column is fixed to the side of the two arc-shaped blades. A sliding column guide is fixed to the surface of the roller. The transverse sliding column slides on the inner wall of the sliding column guide. The transverse sliding column and the sliding column guide are connected by a support spring. An inclined plate is fixed to the end of the two arc-shaped blades. The distance between the two inclined plates gradually increases in the direction away from the arc-shaped blades.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. This invention, by setting up a harvesting mechanism, can push a hand-push cart body, guide the stalks through the strip-shaped opening into the conveying chamber using a rake frame, and cut the stalks with a cutting wheel located in the V-shaped opening. The sprocket motor drives the sprocket to rotate, and the rake plate and rake frame of the conveying chain rake the cut stalks to be conveyed laterally in the conveying chamber. During the process, the rake frame cooperates with the strip-shaped cutting blade to further cut the passing stalks. Finally, the stalks are discharged from one side of the conveying chamber.

[0035] 2. By setting a Y-shaped lever, the present invention can play a certain limiting role during transportation, making it easier to move the stem. It can also cooperate with the forward and reverse rotation of the sprocket motor to achieve transportation of the stem in different directions.

[0036] 3. This invention features a movable strip-shaped cutting blade. During the conveying process, the cutting teeth on the side of the strip-shaped cutting blade assist in cutting. When cutting difficulties occur, the strip-shaped cutting blade deflects based on the deformation of the torsion spring to avoid the obstacle, allowing the structure to pass through. During passage, the cutting teeth continue to assist in cutting. Since multiple sets of strip-shaped cutting blades are provided, cutting efficiency can be guaranteed without jamming.

[0037] 4. By setting up an auxiliary crushing mechanism, the present invention can extend the roller frame on the side of the stem output direction. Based on the operation of the roller motor, the roller is driven to rotate, and then the falling stem is picked up by the toothed hook. With the cooperation of the blade holder and the crushing blade, the hooked stem is crushed in an auxiliary manner, thereby improving the crushing effect.

[0038] 5. Because the stalk conveying direction is variable, and the hand-push vehicle body is equipped with auxiliary crushing mechanisms on both sides with adjustable positions, this invention can better adapt to S-shaped harvesting routes. Attached Figure Description

Detailed Implementation

[0047] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] Example 1:

[0050] An automatic harvesting device for processing grass stems, such as Figure 1-7 As shown, the device includes a hand-push vehicle body 1, with a harvesting mechanism installed at the front end and a push frame 2 at the rear end. The harvesting mechanism includes:

[0051] The upright frame 4 has multiple wheel chain assemblies installed on the side of the upright frame 4 near the hand-push type vehicle body 1;

[0052] Mounting bracket 10 is installed on the side of the upright 4 away from the hand-push type vehicle body 1. Mounting bracket 10 has an L-shaped structure and evenly distributed strip-shaped openings 20 are provided on the mounting bracket 10.

[0053] The reeling frame 6 is installed on the side of the mounting frame 10 away from the upright frame 4, and the strip opening 20 is located between the tail ends of two adjacent reeling frames 6; the width of the reeling frame 6 gradually increases towards the mounting frame 10.

[0054] The cutting wheel 21 is mounted in a V-shaped opening on the mounting frame 10. The cutting wheel 21 is rotatably mounted in the mounting frame 10, and one side of the cutting wheel 21 is exposed in the V-shaped opening. The mounting frame 10 is provided with a drive unit, such as a motor, to drive the cutting wheel 21 to rotate.

[0055] A conveying cavity is formed between the upright frame 4 and the mounting frame 10. The wheel and chain assembly includes a sprocket 11 and a conveying chain 12. The conveying chain 12 is installed on the outside of the two sprockets 11. The sprockets 11 on the same side are coaxially installed. The shaft of the sprocket 11 is rotatably installed on the inner wall of the upright frame 4. A sprocket motor 19 for driving the sprockets 11 to rotate is installed on the top of the upright frame 4. Equally spaced baffles 13 are installed on the lowest conveying chain 12, and equally spaced baffles 18 are installed on the remaining conveying chains 12. The upright frame 4 has an opening for the conveying chain 12, baffles 13 and baffles 18 to pass through. A transverse opening 22 is opened on the baffle 18. A strip cutter 23 is installed on the mounting frame 10. One end of the strip cutter 23 is located in the conveying cavity, and the position of the strip cutter 23 is adapted to the transverse opening 22.

[0056] By setting up a harvesting mechanism, the hand-push cart 1 can be pushed and guided by the rake frame 6, so that the stalks enter the conveying chamber through the strip opening 20. The cutting wheel 21 located in the V-shaped opening works to cut the stalks. The sprocket motor 19 drives the sprocket 11 to rotate. The rake plate 13 and the rake frame 18 of the conveying chain 12 are used to move the cut stalks, so that they are transported laterally in the conveying chamber. During the process, the rake frame 18 cooperates with the strip cutting blade 23 to further cut the passing stalks. Finally, the stalks are discharged from one side of the conveying chamber.

[0057] For ease of transport; such as Figure 3 , Figure 4 As shown, the ends of the lever 18 are bent to both sides to form a Y-shaped structure;

[0058] By setting a Y-shaped lever 18, a certain limiting function can be played during conveying, making it easier to move the stem. It can also be used to convey the stem in different directions based on the forward and reverse rotation of the sprocket motor 19.

[0059] To facilitate the drainage of the stems; such as Figure 1 As shown, guide blocks 7 are fixed at both ends of the upright frame 4 near the mounting frame 10. The sidewall of the guide block 7 is an arc-shaped structure with a raised center.

[0060] To avoid structural jamming; such as Figure 1As shown, a cutter seat 24 is installed on the side of the mounting frame 10 away from the upright frame 4. The mounting frame 10 has an opening for the strip-shaped cutter 23 to pass through. One end of the strip-shaped cutter 23 is rotatably mounted on the cutter seat 24 via a shaft. The cutter seat 24 and the strip-shaped cutter 23 are connected by a torsion spring 25. Multiple cutting teeth are provided on the two side walls of the strip-shaped cutter 23.

[0061] The width of the slit should meet the deflection requirements of the strip cutting blade 23;

[0062] By setting up movable strip cutters 23, the cutting teeth on the side of the strip cutters 23 are used for auxiliary cutting during the conveying process. When cutting difficulties occur, the strip cutters 23 deflect and avoid the structure based on the deformation of the torsion spring 25, so that the structure can pass through. When passing through, the cutting teeth continue to assist cutting. Since there are multiple sets of strip cutters 23, cutting efficiency can be guaranteed without jamming.

[0063] To better guide the stem into the conveying chamber; such as Figure 3 As shown, a pair of inclined plates 5 are fixed on the side of the mounting frame 10 away from the upright frame 4. Each pair of inclined plates 5 has a figure-eight structure, and the ends of the inclined plates 5 extend to the side of the strip opening 20.

[0064] By setting the inclined plate 5, the stem can be guided more smoothly into the conveying chamber.

[0065] To facilitate adjustment of the angle of the harvesting mechanism; such as Figure 2 , Figure 3 As shown, the hand-push type vehicle body 1 is equipped with an angle adjustment mechanism, which includes:

[0066] The first hydraulic cylinder 17 is mounted on the mounting base 16, which is hinged to the hand-push type vehicle body 1.

[0067] Sleeve 15 is installed at the output end of the first hydraulic cylinder 17;

[0068] Connecting frame 14, two connecting frames 14 are installed on the side of the upright frame 4 near the hand-push type vehicle body 1. One connecting frame 14 is hinged to the hand-push type vehicle body 1, and a support shaft is installed on the other connecting frame 14. Sleeve 15 is rotatably installed on the support shaft.

[0069] To facilitate auxiliary crushing processing; such as Figure 5 As shown, an auxiliary crushing mechanism is installed on the side of the hand-push vehicle body 1, and the auxiliary crushing mechanism includes:

[0070] Roller frame 8, on which a rotating roller 32 is rotatably mounted, and the surface of the rotating roller 32 is provided with multiple teeth 28;

[0071] Side bracket 9 is installed on one side of roller frame 8. A knife holder 29 is installed on the side bracket 9. The position of the knife holder 29 is adapted to the tooth 28. The tooth 28 and the knife holder 29 have a hook-shaped structure with opposite directions. A crushing knife 27 is installed on the knife holder 29.

[0072] A rotary roller motor 30 is mounted on one side of the outer wall of the roller frame 8 and is used to drive the rotary roller 32 to rotate.

[0073] Position adjustment component, used to adjust the position of roller frame 8.

[0074] To facilitate adjustment of the structural position; such as Figure 5 As shown, the position adjustment assembly includes a second hydraulic cylinder 31, which is mounted on the hand-push type vehicle body 1. A lifting base 26 is mounted on the output end of the second hydraulic cylinder 31, and a third hydraulic cylinder 3 is mounted on the lifting base 26. The roller frame 8 is fixed to the output end of the third hydraulic cylinder 3.

[0075] By setting an auxiliary crushing mechanism, the roller frame 8 on the side of the stem output direction can be extended. Based on the operation of the roller motor 30, the roller 32 is driven to rotate, and the pick teeth 28 are used to hook the falling stem. With the cooperation of the cutter holder 29 and the crushing blade 27, the hooked stem is crushed in an auxiliary manner, which improves the crushing effect.

[0076] Since the stalk conveying direction of the present invention is variable, and both sides of the hand-push vehicle body 1 are provided with auxiliary crushing mechanisms with adjustable positions, it can be better adapted to S-shaped route harvesting.

[0077] Example 2:

[0078] An automatic harvesting device for processing grass stems, such as Figure 6 As shown, in order to achieve better crushing, this embodiment makes the following improvements based on embodiment 1: an auxiliary crushing mechanism is installed on the side of the hand-push vehicle body 1, and the auxiliary crushing mechanism includes:

[0079] A roller frame 8 is rotatably mounted on the roller frame 8. The surface of the roller 32 is provided with multiple sets of arc-shaped blades 34. Two arc-shaped blades 34 in each set are symmetrically arranged. A transverse sliding column 33 is fixed to the side of the two arc-shaped blades 34. A sliding column guide frame 36 is fixed to the surface of the roller 32. The transverse sliding column 33 slides on the inner wall of the sliding column guide frame 36. The transverse sliding column 33 and the sliding column guide frame 36 are connected by a support spring 35. An inclined plate is fixed to the end of the two arc-shaped blades 34. The distance between the two inclined plates gradually increases in the direction away from the arc-shaped blades 34.

[0080] Side support 9 is installed on one side of roller frame 8. A ball head rod 37 is installed on the side support 9. The spherical end of the ball head rod 37 extends to the movement path of the inclined plate.

[0081] A rotary roller motor 30 is mounted on one side of the outer wall of the roller frame 8 and is used to drive the rotary roller 32 to rotate.

[0082] Position adjustment assembly, used to adjust the position of roller frame 8;

[0083] By setting an auxiliary crushing mechanism, the roller frame 8 on the side of the stem output direction can be extended. Based on the operation of the roller motor 30, the roller 32 is driven to rotate, and then the arc-shaped blades 34 are used to crush the stem. As the roller 32 rotates, the inclined plate contacts the ball head rod 37, and the distance between the two arc-shaped blades 34 increases, thereby tearing the incompletely crushed stems to both sides to improve the crushing effect.

[0084] To facilitate adjustment of the structural position; such as Figure 5 As shown, the position adjustment assembly includes a second hydraulic cylinder 31, which is mounted on the hand-push type vehicle body 1. A lifting base 26 is mounted on the output end of the second hydraulic cylinder 31, and a third hydraulic cylinder 3 is mounted on the lifting base 26. The roller frame 8 is fixed to the output end of the third hydraulic cylinder 3.

[0085] Example 3:

[0086] An automatic harvesting device for processing grass stems, such as Figure 7 As shown, this embodiment is based on embodiment 1: the hand-push vehicle body 1 is replaced with vehicle body 38, and harvesting is achieved by driving vehicle body 38. Accordingly, the corresponding dimensions of the structure should be adjusted accordingly. Control buttons, control panels, etc. should be adjusted from the hand-push vehicle body 1 and push frame 2 to be set in the cab of vehicle body 38. This embodiment only provides another implementation method. For the adaptive adjustments of dimensions, component installation positions, etc., those skilled in the art can obtain a complete solution based on the actual situation and their own professional knowledge. Since the arrangement of the control panel and other structures is not the focus of the present invention, it will not be described in detail.

[0087] For the parts not disclosed in detail in this invention, those skilled in the art can ensure the smooth implementation of the solution of this invention based on common sense, normal logical thinking and existing technology.

[0088] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
