Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a mushroom straw harvester. BACKGROUND

[0002] Mushroom straw harvesting is a very important link in mushroom straw processing.

[0003] At present, when planting mushroom straw, the planters usually adopt open-air large-area and scattered plot planting. In the case of large-scale planting, due to the problems of landform, etc., the current main method is manual harvesting. This operation method not only has low efficiency, but also easily causes damage to the human body during the harvesting process due to improper operation, etc.

[0004] The existing mushroom straw harvesting machinery has a silage machine, which is mainly used for one-time harvesting and crushing treatment of mushroom straw in large plots. Although it has the advantage of high efficiency, its cost is also high, which is a heavy burden for small and medium-sized farmers, and its applicability is poor. In addition, some planters also use backpack mowers and mowing machines for harvesting operations. Among them, the backpack mower is simple to operate, but has high labor intensity and great safety hazards in harvesting mushroom straw. Compared with the backpack mower, the labor intensity of the mowing machine is reduced, but the reciprocating harvesting device used by the mowing machine consumes a lot of cutting tools when used for mushroom straw harvesting, and is prone to jamming and other phenomena.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] The purpose of the present application is to provide a grass harvesting machine to solve the problems existing in the prior art, improve the grass harvesting efficiency, and have good adaptability.

[0033] In order to make the above-mentioned purposes, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] As Figures 1-10As shown, this embodiment provides a mushroom grass harvester, including a front-end harvesting module 1, a mushroom grass conveying module 2, a folding module 3, and a moving chassis 4. The moving chassis 4 is used to realize the walking function. The front-end harvesting module 1 is rotatably mounted on the front end of the moving chassis 4 and is used to harvest mushroom grass. Compared with the traditional manual harvesting method, it can reduce labor intensity, improve harvesting efficiency, and enhance work safety. The folding module 3 is mounted on the moving chassis 4 and is connected to the front-end harvesting module 1. The folding module 3 can drive the front-end harvesting module 1 to rotate around a horizontal axis, thereby lifting or lowering the front-end harvesting module 1. When the mushroom grass harvester encounters the ground during its forward movement... If there are obstacles, the front harvesting module 1 can be raised by the folding module 3 to prevent it from hitting obstacles and affecting the movement of the mushroom grass harvester, thus improving the terrain adaptability of the mushroom grass harvester. At the same time, it can also protect the front harvesting module 1. During normal harvesting, the front harvesting module 1 is lowered by the folding module 3 to ensure that it can harvest the mushroom grass smoothly. The mushroom grass transmission module 2 is installed on the moving chassis 4 and is located behind the front harvesting module 1. The mushroom grass transmission module 2 is used to transfer the mushroom grass harvested by the front harvesting module 1 to the outside of the mushroom grass harvester for easy collection later. It is convenient to use.

[0035] Specifically, such as Figures 2-5 As shown, the front-end harvesting module 1 includes a mounting frame 5, a rotary harvesting assembly, a feeding assembly, a harvesting drive element, and a feeding drive element. The mounting frame 5 is connected to the front end of the motion chassis 4 via a folding module 3. Both the rotary harvesting assembly and the feeding assembly are mounted on the mounting frame 5, with the feeding assembly positioned above the rotary harvesting assembly. Both the harvesting drive element and the feeding drive element are mounted on the mounting frame 5. The harvesting drive element can drive the rotary harvesting assembly to rotate and harvest the mushroom grass, and the feeding drive element can drive the feeding assembly to rotate. When the feeding assembly rotates, it can feed the harvested mushroom grass into the mushroom grass transfer module 2. To achieve the connection between the various structures, the front-end harvesting module also includes multiple nuts 12 and multiple bolts 13.

[0036] The rotary harvesting assembly includes a blade guard element 6, two dividers 9, and two rotating blades 10. The two dividers 9 are installed on both sides of the front end of the mounting base 5. The front ends of the two dividers 9 are pointed, and the dividers 9 are used to gather the mushroom grass to be harvested between the two dividers 9. The blade guard element 6 is installed at the lower end of the mounting base 5. The two rotating blades 10 are located on the same horizontal plane and are rotatably mounted above the blade guard element 6. The front end of the blade guard element 6 extends to the front of the rotating blades 10. During the harvesting process, when a large hard object is encountered in front, the blade guard element 6 can push the hard object away, thereby preventing the rotating blades 10 from directly contacting the hard object and causing damage. The hard object can then be removed manually. When a smaller hard object is encountered in front, the smaller hard object can pass through the gap below the blade guard element 6, so that the rotating blades 10 can cut the mushroom grass under the protection of the blade guard element 6. There are two harvesting drive elements, which drive the two rotating blades 10 to rotate respectively.

[0037] The blade guard element 6 includes a blade guard plate and multiple blade guard forks. The blade guard plate is horizontally arranged and perpendicular to the forward direction of the moving chassis 4. The multiple blade guard forks are arranged sequentially along the length of the blade guard plate. The blade guard forks extend rotating blades 10, so that the blade guard forks are the first to contact the hard object.

[0038] The harvesting drive component includes a harvesting drive motor, a main harvesting sprocket, a harvesting chain 14, and a driven harvesting sprocket. The harvesting drive motor is coaxially connected to the main harvesting sprocket. The main harvesting sprocket and the driven harvesting sprocket are connected by the harvesting chain 14. The harvesting drive motor drives the main harvesting sprocket to rotate, and the main harvesting sprocket drives the driven harvesting sprocket to rotate via the harvesting chain 14, thereby rotating the rotating blade 10. A chain guard plate 15 is fitted around the outer periphery of the harvesting chain 14 to prevent debris from entering the harvesting chain 14 and affecting its rotation. The chain guard plate 15 is mounted on the mounting base 5. A hollow spline flange shaft 17 is coaxially connected to the driven harvesting sprocket. Preferably, the hollow spline flange shaft 17 includes an upper shaft and a lower shaft, with the lower end of the upper shaft extending into the lower shaft. Inside the shaft, the lower end of the hollow spline flange shaft 17 is rotatably connected to the bottom of the mounting base 5 via a ball roller bearing 20. A long shaft bolt 19 is connected to the lower end of the hollow spline flange shaft 17. A T-shaped washer 23 is fitted around the outer circumference of the lower shaft of the hollow spline flange shaft 17. The T-shaped washer 23 is located between the long shaft bolt 19 and the harvester sprocket. The rotating blade 10 is fitted around the outer circumference of the lower shaft of the hollow spline flange shaft 17. A flange 22 is provided between the rotating blade 10 and the lower shaft of the hollow spline flange shaft 17. The rotating blade 10 is connected to the outer circumference of the lower shaft of the hollow spline flange shaft 17 via the flange 22 and bolts 13. A motor cover 7 is installed on each side of the mounting base 5. Each harvester drive motor is installed in the motor cover 7 on the corresponding side.

[0039] A thrust bearing 21 is also fitted around the outer periphery of the hollow spline flange shaft 17. The inner ring of the thrust bearing 21 is connected to the upper middle part of the rotating blade 10. The feeding assembly includes two reeling discs 11, which are respectively fitted around the outer periphery of the two hollow spline flange shafts 17. The middle part of the reeling disc 11 is a spline bushing 18, which is connected to the upper shaft of the hollow spline flange shaft 17 by a ball roller bearing 20. A T-shaped washer 23 is also provided around the outer periphery of the hollow spline flange shaft 17, and the friction between the hollow spline flange shaft 17 and the T-shaped washer 23 is reduced by a thrust ball bearing 52. The reeling discs 11 are located above the rotating blade 10, and the two reeling discs 11 are located in the same water. On the plane, the lower middle part of the reeling disc 11 is connected to the outer ring of the thrust bearing 21. The lower middle part of the reeling disc 11 and the thrust bearing 21 are connected by a transition. The upper end of the reeling disc 11 is radially fixed to the hollow spline flange shaft 17, and a side cover 16 is provided between the two. The feeding drive element includes two feeding drive motors 8. Both feeding drive motors 8 are mounted on the mounting base 5, and the two feeding drive motors 8 drive the two reeling discs 11 to rotate in opposite directions. When the two reeling discs 11 rotate, the harvested straw can be fed into the straw transfer module 2 under the action of inertia and the pushing action of the reeling discs 11. The feeding drive motors 8 are located above the reeling discs 11.

[0040] Through the above design of the reeling disc 11 and the rotating blade 10, differential drive of the coaxially arranged rotating blade 10 and reeling disc 11 is achieved. The specific process is as follows: At the start of work, the harvesting drive motor and the feeding drive motor 8 work simultaneously, and the harvesting drive motor and the feeding drive motor 8 rotate in the same direction. The harvesting drive motor is used to drive the rotating blade 10 to rotate, and the feeding drive motor 8 is used to drive the reeling disc 11 to rotate. The speed of the feeding drive motor 8 is lower than that of the harvesting drive motor. In order to avoid mutual interference between the harvesting drive motor and the feeding drive motor 8, a thrust bearing 21 is designed. The thrust bearing 21 is used as the differential drive core. During operation, the long shaft bolt 19 of the hollow spline flange shaft 17, the lower shaft of the hollow spline flange shaft 17, and the lower shaft of the hollow spline flange shaft 17 can be driven. The ball roller bearing 20, flange 22, T-type washer 23, and inner ring of thrust bearing 21 are considered as one unit, while the side cover 16, upper shaft of hollow spline flange shaft 17, spline bushing 18, ball roller bearing 20 located at the upper end of hollow spline flange shaft 17, reel 11, and outer ring of thrust bearing 21 are considered as one unit. Since the inner ring of thrust bearing 21 is driven by harvesting drive motor, and the outer ring of thrust bearing 21 is driven by feeding drive motor 8, and the speed of the inner ring of thrust bearing 21 is greater than the speed of the outer ring of thrust bearing 21, the action process can be regarded as the movement of the inner ring of thrust bearing 21 relative to the outer ring of thrust bearing 21. The following relationship exists between the two: speed of inner ring of thrust bearing 21 = speed of outer ring of thrust bearing 21 + relative speed, thereby realizing differential drive.

[0041] Through the above design, this embodiment can cut and gather the mushroom grass for backward transport during harvesting. The disc-type rotary cutter has a longer service life compared to the traditional reciprocating cutter blade. At the same time, compared to the traditional disc cutting table, a blade guard element 6 is added. In addition, differential speed drive of the rotating blade 10 and the reeling disc 11 can be realized to separately control the speed of the rotating blade 10 and the reeling disc 11, thereby better realizing the mushroom grass harvesting process and having a greater advantage in non-crushing mushroom grass harvesting.

[0042] like Figure 6 As shown, the Juncao (a type of grass) transmission module 2 includes a transmission base 24, a transmission guard plate 30, a transmission drive element, and several transmission units arranged in sequence along the vertical direction. Preferably, the transmission units are three-layered. The transmission guard plate 30 is installed at the lower end of the transmission base 24 and at the upper end of the moving chassis 4. The transmission units are rotatably mounted on the transmission base 24. The rotation direction and rotation speed of each transmission unit are the same. By setting multiple transmission units, it can adapt to the harvesting of Juncao at different heights, thus improving adaptability. The transmission drive element can drive the transmission units to rotate and cause the transmission units to transport the harvested Juncao to one side of the moving chassis 4.

[0043] The transmission drive element is a transmission drive motor 29. Two vertically arranged transmission shafts are rotatably mounted on the transmission base 24. The two transmission shafts are a main transmission shaft 27 and a driven transmission shaft, respectively. The transmission unit includes a transmission main sprocket 26, a transmission chain 25, and a transmission driven sprocket. The transmission main sprocket 26 and the transmission driven sprocket are connected by the transmission chain 25. The transmission main sprocket 26 is connected to the outer periphery of the main transmission shaft 27, and the transmission driven sprocket is connected to the outer periphery of the driven transmission shaft. The main transmission shaft 27 is connected to the transmission drive motor 29 and can rotate under the drive of the transmission drive motor 29. Both the main transmission shaft 27 and the driven transmission shaft are mounted on the transmission guard plate 30 through bearing seats 28.

[0044] like Figure 7As shown, the folding module 3 includes a fixed shaft 36, two fisheye head bearing tie rods 34, two Y-type hydraulic cylinder connectors 33, two large hydraulic cylinders 31, and two small hydraulic cylinders. The fixed shaft 36 is connected to the transmission base frame 24. The large ends of the two fisheye head bearing tie rods 34 are respectively connected to the two ends of the fixed shaft 36. The small ends of the two fisheye head bearing tie rods 34 are respectively connected to the power output ends of the two large hydraulic cylinders 31 through a Y-type hydraulic cylinder connector 33. The mounting ends of the two large hydraulic cylinders 31 are rotatably connected to the moving chassis 4. The mounting ends of the two small hydraulic cylinders are connected to the transmission base frame 24 through fixing pins 35. The power output ends of the two small hydraulic cylinders are connected to the power output ends of the large hydraulic cylinders 31 through fixing pins 35. Springs 32 are provided between the mounting ends and power output ends of the large hydraulic cylinders 31, and between the mounting ends and power output ends of the small hydraulic cylinders. In this embodiment, the specific unfolding and retraction process of the folding module 3 is as follows: When an obstacle is encountered in the forward direction and the front-end harvesting module 1 needs to be retrieved, the two large hydraulic cylinders 31 retract first. After the large hydraulic cylinders 31 reach their positions, the small hydraulic cylinder retracts. After the small hydraulic cylinder retracts to its position, the large hydraulic cylinder 31 begins to extend until the mounting base 5 is close to the battery cover 42. That is, the front-end harvesting module 1 rotates 60°, and the large hydraulic cylinder 31 stops, completing the folding action. When the obstacle is overcome and normal harvesting is required, the front-end harvesting module 1 needs to be lowered. At this time, the two large hydraulic cylinders 31 retract first. After the large hydraulic cylinders 31 retract to their positions, the small hydraulic cylinder extends. When the small hydraulic cylinder extends to its position, the large hydraulic cylinder 31 extends until the mounting base 5 is perpendicular to the battery cover 42, completing the unfolding action. That is, at this time, the front-end harvesting module 1 is reset. On the other hand, when the front-end harvesting module 1 is fully unfolded, the large hydraulic cylinders 31 and the small hydraulic cylinder, after releasing pressure, can provide a certain shock absorption effect for the front-end harvesting module 1. In this embodiment, the folding module 3 can also directly utilize the lifting and lowering structure of a conventional bulldozer bucket, as long as it can achieve the lifting and lowering of the front-end harvesting module 1.

[0045] like Figures 8-10As shown, the sports chassis 4 includes a main frame 37, a rear axle assembly 43, a steering front axle assembly 51, a steering assembly 45, an engine 38, a generator 47, an electromagnetic clutch 39, a universal joint drive shaft 40, a first-stage reduction gearbox 46, a hydraulic pump station 41, and a battery pack 48. There are two universal joint drive shafts 40, designated as the first and second universal joint drive shafts. The two ends of the rear axle assembly 43 are connected to the main frame 37 via load-bearing steel plates 44. The front axle assembly 51 is connected to the main frame 37 via U-bolts 49. The steering assembly 45 is connected to the main frame 37 and can cooperate with the steering front axle assembly 51 to provide steering power. The engine 38 is connected to the main frame 37 and is used to provide travel power. The engine 38 and the first universal joint drive shaft 40 are connected via an electromagnetic clutch 39, which is used to control the on / off of power transmission between the engine 38 and the first universal joint drive shaft 40. The first-stage reduction gearbox 46 is connected to... At the lower end of the main frame 37, the power input shaft of the first-stage reduction gearbox 46 is connected to the second universal joint drive shaft 40 and a coupling 50. The second universal joint drive shaft 40 serves as the power input, and the coupling 50 connects to the generator 47 and drives its movement. The power output shaft of the first-stage reduction gearbox 46 is connected to the rear axle assembly 43 via the first universal joint drive shaft 40 and provides power to the rear axle assembly 43, thereby enabling the motion chassis 4 to operate in a rear-axle front-drive mode. Anti-skid tires can also be equipped. In this embodiment, the bacteria... The grass harvester can maintain good grip when encountering steep terrain. At the same time, the moving chassis 4 has mechanical, electric and hydraulic output functions. The hydraulic pump station 41 is connected to the main frame 37 and is used to provide hydraulic oil to the folding module 3. The generator 47 is connected to the main frame 37 and is electrically connected to the battery pack 48 to supply power to the battery pack 48. The battery pack 48 is installed above the rear axle assembly 43 and is covered by a battery cover plate 42 to protect the battery pack 48.

[0046] In this embodiment, when the mushroom grass harvester is in use, the moving chassis 4 drives the mushroom grass harvester forward as the engine 38 starts. The steering assembly 45 can control the direction of the mushroom grass harvester. During the harvesting process, the rotating blade 10 is protected by the blade guard element 6 to avoid damage to the rotating blade 10. The cut mushroom grass is brought closer to the mushroom grass transmission module 2 by inertia and the action of the two reeling discs 11. When the mushroom grass comes into contact with the mushroom grass transmission module 2, it is transmitted to the left or right by the action of the transmission chain 25. At the same time, since the transmission chain 25 has multiple layers, it can adapt to mushroom grass of different heights. The mushroom grass harvester in this embodiment adopts a hybrid electric drive and is suitable for small and medium-sized plots. It solves the problems of low harvesting efficiency of existing backpack harvesters, manual harvesting of mushroom grass, and difficulty in ensuring harvesting height of hand-held harvesters.
