Description

Technical Field

[0001] The invention relates to the field of agricultural machinery, and in particular to a forage harvester. Background Art

[0002] At present, when harvesting grass, special grass harvesters are usually used, including large grass harvesters and small handheld harvesters. Among them, handheld harvesters are widely used in small harvesting work due to their portability and strong adaptability. The existing handheld grass harvesters are mainly composed of a cutting part and a mounting part. The mounting part is used to tie the cutting part to the user's waist. Then, when cutting grass, the user swings his waist to drive the cutting part to swing, so as to cut the grass in the front fan-shaped area.

[0003] However, when cutting, the user needs to frequently swing the waist to harvest the grass in front within a certain range, which causes a heavy burden on the user's waist. Long-term use can easily cause lumbar muscle strain. Moreover, after the grass is cut, in order to facilitate the subsequent processing of the grass, the grass needs to be piled together. However, the existing handheld harvesters lack the function of centrally stacking the grass, making the grass relatively scattered. For this reason, this scheme proposes a grass harvester. Summary of the invention

[0004] The forage harvester provided by the present invention solves the problems of frequent waist swinging of the user and inconvenience in centralized stacking of forage when using the forage harvester in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A forage harvester, comprising: The fixing part includes a mounting plate, a waist protector fixed to a long side of one side of the mounting plate, and straps installed at both ends of the waist protector, and two detachable supporting feet are installed on the bottom surface of the mounting plate; The cutting part includes a rotating disk rotatably connected to the top surface of the mounting plate through a rotating shaft, a mounting rod fixed to the outer periphery of the rotating disk, a mounting disk hinged to the other end of the mounting rod, a fixed shaft rotatably connected to the bottom surface of the mounting disk, a mounting head fixed to the bottom of the fixed shaft, and a plurality of cutting ropes installed on the outer periphery of the mounting head, wherein the mounting disk is a hollow structure, and an adjusting mechanism for adjusting the angle of the mounting disk is installed on the mounting rod; A buffer portion, which is mounted on the bottom surface of the mounting plate and is used to limit the rotation of the mounting plate; The collecting part includes a mounting shaft rotatably connected to the outer periphery of the mounting plate, a support plate fixed to one end of the mounting shaft, the other end of the mounting shaft extends to the inner side of the mounting plate, a stopper for limiting the rotation direction of the mounting shaft is installed inside the mounting plate, and a reset member is installed between one end of the mounting shaft located inside the mounting plate and the inner wall of the mounting plate; A cleaning part, comprising a mounting ring rotatably connected to the bottom surface of the mounting plate and a plurality of scrapers fixed to the outer periphery of the mounting ring, wherein the mounting ring is movably sleeved on the outer periphery of the fixed shaft; A driving part, which is installed inside the mounting plate and is used to drive the mounting ring to rotate while the buffer part stops the mounting plate from rotating; The unloading part is installed on the inner side of the installation plate and is used to drive the installation shaft to rotate while the installation ring rotates.

A buffer spring is installed between the outer wall on the other side of the first piston plate and the inner wall of the buffer gas cylinder. The bottom of the rotating shaft extends to the bottom of the mounting plate and is fixed with a fixed plate that cooperates with the movable rod.

[0016] By means of the above technical solution, the rotation of the cutting part due to inertia can be effectively slowed down.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0031] Example 1: Please combine Figure 1 - Fig.11 , a forage harvester of this embodiment includes: The fixing part includes a mounting plate 1, a waist protector 14 fixed to a long side of the mounting plate 1, and straps 13 installed at both ends of the waist protector 14. The waist protector 14 is an arc-shaped plate structure and is covered with a soft pad on the outside. The two straps 13 are fixed by Velcro.

[0032] Two detachable supporting feet are installed on the bottom surface of the mounting plate 1, and the supporting feet include a movable column 17, a sleeve 15 movably sleeved on the outer periphery of the top end of the movable column 17, and a roller installed at the bottom of the movable column 17. A positioning bolt 16 is screwed on the outer periphery of the bottom of the sleeve 15, and one end of the positioning bolt 16 abuts against the outer periphery of the movable column 17. A connecting plate is sleeved on the outer periphery of the sleeve 15, and a connecting bolt is screwed on the connecting plate. Two sockets 20 for installing the sleeve 15 are provided on the bottom surface of the mounting plate 1, and the top of the sleeve 15 is inserted into the socket 20. Bolt holes that match the connecting bolts are provided on the bottom surface of the mounting plate 1. After tying the mounting plate 1 to the body, the length of the supporting feet is adjusted so that the roller contacts the bottom surface, so that the supporting feet can be used to support the weight of the mounting plate and reduce the weight of the user. At the same time, when the supporting feet are not needed, the supporting feet can also be removed from the mounting plate 1.

[0033] The cutting part includes a turntable 11 rotatably connected to the top surface of the mounting plate 1 through a rotating shaft 26, a mounting rod 5 fixed on the outer periphery of the turntable 11, a mounting plate 2 hinged at the other end of the mounting rod 5, a fixed shaft rotatably connected to the bottom surface of the mounting plate 2, a mounting head 19 fixed at the bottom of the fixed shaft, and a plurality of cutting ropes 4 installed on the outer periphery of the mounting head 19. A cutting motor 18 is installed on the top surface of the mounting plate 2. The output shaft of the cutting motor 18 is fixedly connected to the top of the fixed shaft, so that the fixed shaft is driven to rotate by the rotation of the cutting motor 18. A switch for controlling the start and stop of the cutting motor 18 is installed on the top surface of the mounting plate 1. An adjusting rod 12 is fixed at a position of the top surface of the mounting plate 2 deviating from the center of the circle. By holding the adjusting rod 12, the mounting plate 2 can be easily rotated, thereby driving the mounting plate 2 to swing, and then cutting the grass in the front fan-shaped area.

[0034] The mounting plate 2 is a hollow structure, and an adjusting mechanism for adjusting the angle of the mounting plate 2 is installed on the mounting rod 5. The adjusting mechanism includes an adjusting sleeve 7 movably sleeved on the outer periphery of the mounting rod 5, a connecting rod 6 hinged on the outer periphery of the adjusting sleeve 7, and a locking bolt 8 threadedly connected to the outer periphery of the adjusting sleeve 7. The other end of the connecting rod 6 is hinged to the top surface of the mounting plate 2, and the other end of the locking bolt 8 abuts against the outer periphery of the mounting rod 5. A handle 9 is fixed to the outer periphery of the adjusting sleeve 7. Holding the handle 9 and moving the adjusting sleeve 7 along the length direction of the mounting rod 5 can drive the mounting plate 2 to rotate up and down, thereby adjusting the pitch angle of the mounting plate 2, and then the angle of the mounting plate 2 can be adaptively adjusted according to the different slopes of the breeding grounds, so that it can be cut more closely to the ground.

[0035] The buffer part is installed on the bottom surface of the mounting plate 1 and is used to limit the rotation of the mounting plate 2. The buffer part includes a buffer cylinder 25 fixed to the bottom surface of the mounting plate 1, a first piston plate 44 installed in the buffer cylinder 25, and a movable rod 24 fixed to the outer wall of one side of the first piston plate 44. The buffer cylinder 25 and the movable rod 24 are both annular structures, and the buffer cylinder 25 and the movable rod 24 are coaxially arranged with the rotating shaft 26. A buffer spring is installed between the outer wall of the other side of the first piston plate 44 and the inner wall of the buffer cylinder 25. The bottom of the rotating shaft 26 extends to the bottom of the mounting plate 1 and is fixed with the movable rod The fixed plate 27 matched with 24, the rotation of the turntable 11 drives the rotating shaft 26 to rotate synchronously at the same time. When the turntable 11 drives the mounting plate 2 to rotate to the set cutting angle, the fixed plate 27 will collide with the movable rod 24, and the inertia brought by the rotation of the cutting part will continue to press the movable rod 24 to move toward the inside of the buffer gas cylinder 25, and the first spring will also be compressed, thereby providing a reverse repulsive force to the movable rod 24, thereby eliminating inertia and reducing the swing amplitude after cutting is completed. Moreover, when the cutting part rotates, the first spring can also provide thrust, so that the cutting part can rotate more easily.

[0036] The collecting part includes a mounting shaft 28 rotatably connected to the outer periphery of the mounting disk 2, and a support plate 3 fixed to one end of the mounting shaft 28. The support plate 3 is a mesh plate that can reduce the air resistance when it swings. The other end of the mounting shaft 28 extends to the inner side of the mounting disk 2. As the cutting part swings during cutting, the cut grass is held by the support plate 3 and swings in the same direction as the cutting part, so that the cut grass can be concentrated and piled on the same side.

[0037] A limit piece for limiting the rotation direction of the mounting shaft 28 is installed inside the mounting disk 2, and the limit piece includes a limit block 33 fixed to the inner wall of the top of the mounting disk 2 and a fixed block 31 fixed to the outer periphery of the mounting shaft 28. The fixed block 31 cooperates with the limit block 33. When the support plate 3 is in a vertical state, the fixed block 31 abuts against the limit block 33, so that the mounting shaft 28 can only rotate in one direction, and the support plate 3 can only tilt forward, so that the forage collected on the support plate 3 can be more easily poured off the support plate 3 after cutting.

[0038] A reset member is installed between one end of the mounting shaft 28 located inside the mounting disk 2 and the inner wall of the mounting disk 2. The reset member includes a torsion spring 32 sleeved on the outer periphery of the mounting shaft 28 and an abutment block fixed on the inner wall of the mounting disk 2. One end of the torsion spring 32 is clamped with the outer periphery of the mounting shaft 28, and the other end of the reset spring is clamped with the abutment block. The setting of the torsion spring 32 prevents the mounting shaft 28 from rotating easily without external force, and also prevents the support plate 3 from tilting forward when the cutting part swings. Moreover, after the support plate 3 tilts, the torsion spring 32 will restore its deformation, thereby driving the support plate 3 to automatically return to its original position.

[0039] The cleaning part includes a mounting ring 22 rotatably connected to the bottom surface of the mounting disk 2 and a plurality of scrapers 21 fixed to the outer periphery of the mounting ring 22. The mounting ring 22 is movably sleeved on the outer periphery of the fixed shaft. The scrapers 21 are arranged along the radial direction of the mounting disk 2, and the fixed surfaces of the scrapers 21 abut against the bottom surface of the mounting disk 2, so that the scrapers 21 can be driven to rotate while the mounting ring 22 rotates, thereby scraping off grass clippings stuck to the bottom surface of the mounting disk 2 when cutting grass.

[0040] The driving part is installed on the inner side of the mounting plate 2 and is used to drive the mounting ring 22 to rotate while the buffer part stops the mounting plate 2 from rotating. The driving part includes a linkage shaft 42 rotatably connected to the inner wall of the top of the mounting plate 2, a driving gear 41 and a fixed gear 40 sleeved on the outer periphery of the linkage shaft 42, the top of the mounting ring 22 extends to the inner side of the mounting plate 2, and the outer periphery of the portion of the mounting ring 22 located on the inner side of the mounting plate 2 is sleeved with a driven gear ring 39 meshing with the driving gear 41, the diameter of the driving gear 41 is larger than the diameter of the fixed gear 40 and the diameter of the driven gear ring 39, and the driving part also includes a power cylinder 30 installed on the inner side wall of the mounting plate 2, a second piston plate installed in the power cylinder 30, and a driving rack 3 fixed on the outer wall of one side of the second piston plate 8 and a connecting piece installed on the top inner wall of the mounting plate 2 for driving the linkage shaft 42 to reset after rotation, one end of the driving rack 38 extends to the outside of the power cylinder 30 and meshes with the fixed gear 40, the buffer cylinder 25 is connected to the power cylinder 30 through the air pipe 23, the mounting rod 5 is a hollow structure, the air pipe 23 extends to the inside of the mounting plate 2 through the inside of the mounting rod 5, the connecting piece includes a transmission gear ring 35 rotatably connected to the top inner wall of the mounting plate 2, a fixed ring 36 fixed on the top inner wall of the mounting plate 2 and a plurality of elastic members installed between the fixed ring 36 and the transmission gear ring 35, the linkage shaft 42 is located on the inner side of the transmission gear ring 35, and the outer periphery of the linkage shaft 42 is sleeved with a linkage gear 43 meshing with the transmission gear ring 35, the elastic member includes The movable block 37 and the second spring movably sleeved on the outer periphery of the fixed ring 36, and the spring clamping block sleeved on the outer periphery of the fixed ring 36, one end of the movable block 37 is fixedly connected to the outer periphery of the transmission gear ring 35, the second spring is located between the movable block 37 and the spring clamping block, and one end of the second spring is fixedly connected to the movable block 37, and the other end of the second spring is fixedly connected to the spring clamping block. When the movable rod 24 is squeezed by the fixed plate 27, the air in the buffer gas cylinder 25 will be pressed into the inside of the power gas cylinder 30. When the air in the power gas cylinder 30 increases, it will drive the second piston plate to move outward, thereby driving the driving rack 38 to move outward synchronously. After the driving rack 38 moves, it drives the linkage shaft 42 to rotate. After the linkage shaft 42 rotates, it drives the driving gear 41 to rotate, and the driving gear 41 is driven to rotate. After the gear 41 rotates, it drives the driven ring gear 39 to rotate, thereby causing the mounting ring 22 to rotate, and then causing the scraper 21 to rotate, thereby cleaning the bottom surface of the mounting plate 2. While the linkage shaft 42 rotates, it drives the linkage gear 43 to rotate. After the linkage gear 43 rotates, it drives the transmission ring gear 35 to rotate. After the transmission ring gear 35 rotates, it drives the movable block 37 to rotate, thereby compressing the second spring. When the cutting part rotates, the pressure of the fixed plate 27 on the movable rod 24 is reduced, and the second spring and the first spring begin to rebound, thereby driving the transmission ring gear 35 to reverse, and the linkage shaft 42 also reverses accordingly, thereby causing the driving rack to move toward the inside of the power cylinder 30, and the air in the power cylinder 30 is sucked back into the inside of the buffer cylinder 25.

[0041] The unloading part is installed on the inner side of the mounting disk 2 and is used to drive the mounting shaft 28 to rotate while the mounting ring 22 rotates. The unloading part includes a gear ring 34 fixed to the bottom surface of the transmission gear ring 35 and a transmission gear fixed to one end of the mounting shaft 28 located on the inner side of the mounting disk 2. The transmission gear is meshed with the gear ring 34. When the transmission gear ring 35 rotates, the gear ring 34 is driven to rotate synchronously. After the gear ring 34 rotates, it drives the transmission gear to rotate. Therefore, after the cutting part completes a swing, the inertia of the cutting part is used to drive the scraper 21 to rotate, and the mounting shaft 28 is also driven to rotate forward at the same time. At this time, the torsion spring is compressed, thereby driving the support plate 3 to reverse forward, so that the forage piled on the support plate 3 can be laid down.

[0042] The implementation principle of this embodiment is: when in use, the waist protector 14 is fitted near the waist, and then the two straps 13 are tightened so that the waist protector 14 is tightened near the waist, and then the support feet are selected according to personal needs. When the support feet are not used, the support feet do not need to be installed. When the support feet are needed, the support feet are first installed on the bottom surface of the mounting plate 1 and then the length of the support feet is adjusted. When adjusting the length of the support feet, the positioning bolts 16 are first loosened, and then the movable column 17 is pulled out so that the roller can contact the bottom surface. Then tighten the positioning bolt 16, and lock the movable column 17 by relying on the friction between the positioning bolt 16 and the outer periphery of the movable column 17. At this time, the support foot can support the weight of the mounting plate 1 and the entire cutting part, making the user's load lighter and reducing the user's physical energy consumption. Then adjust the pitch angle of the mounting plate 2 so that it can be parallel to the pasture ground. When adjusting, first loosen the locking bolt 8, and then move the adjustment sleeve 7 along the length direction of the mounting rod 5, which can drive the mounting plate 2 to rotate up and down. After the adjustment is completed, tighten the locking bolt 8; When cutting, first start the cutting motor 18, and then swing the cutting part in the counterclockwise direction. After the cutting motor 18 rotates, it drives the fixed shaft to rotate, and after the fixed shaft rotates, it drives the mounting head 19 to rotate, so that the cutting rope 4 rotates at a high speed. When the cutting rope 4 contacts the grass, the grass will be cut off, and the cut grass will be caught by the supporting plate 3, so that the grass is concentrated on the supporting plate 3, and then the grass is transferred to the same side of the operator as the cutting part swings. When the swing angle of the cutting part reaches the maximum angle of personal habit, stop the cutting motor 18, and also stop rotating the turntable 11. At this time, the turntable 11 will continue to rotate counterclockwise under the inertia of the cutting part, so that the fixed The plate 27 will contact the movable rod 24. As the turntable 11 continues to rotate counterclockwise, the fixed plate 27 will continue to press the movable rod 24 to move toward the inside of the buffer cylinder 25. The first spring will also be compressed accordingly. The air in the buffer cylinder 25 will be pressed into the power cylinder 30 through the air pipe 23. When the air in the power cylinder 30 increases, the second piston plate will be driven to move outward, thereby driving the driving rack 38 to move outward synchronously. After the driving rack 38 moves, it will drive the linkage shaft 42 to rotate. After the linkage shaft 42 rotates, it drives the driving gear 41 to rotate. After the driving gear 41 rotates, it drives the driven gear ring 39 to rotate, thereby rotating the mounting ring 22, and then rotating the scraper 21, so as to clean the bottom surface of the mounting disk 2. When the linkage shaft 42 rotates, the linkage gear 43 is driven to rotate. When the linkage gear 43 rotates, the transmission ring gear 35 is driven to rotate forward. When the transmission ring gear 35 rotates, the movable block 37 is driven to rotate, so that the second spring is compressed. When the transmission ring gear 35 rotates forward, the gear ring 34 is driven to rotate synchronously. When the gear ring 34 rotates, it drives the transmission gear to rotate. Therefore, after the cutting part completes a swing, the inertia of the cutting part is used to drive the scraper 21 to rotate and the mounting shaft 28 is driven to rotate forward at the same time. At this time, the torsion spring is compressed, thereby driving the support plate 3 to reverse forward, so that the forage piled on the support plate 3 can be knocked down. When the cutting part is rotated, since the second spring and the first spring will restore their deformation, the transmission ring gear 35 will reverse, and the ring gear 34 will drive the mounting shaft 28 to reverse, so that the support plate 3 will flip back. At the same time, the transmission ring gear 35 will drive the linkage shaft 42 to reverse, so as to drive the driving rack 38 to move toward the inside of the power cylinder 30, and the air in the power cylinder 30 will be sucked back into the buffer cylinder 25. After the air in the buffer cylinder 25 increases, the first piston plate 44 and the movable rod 24 will move toward the outside of the buffer cylinder 25. At the same time, the restoration of the first spring will also help the first piston plate 44 to move toward the outside of the buffer cylinder 25, so that the movable rod 24 will drive the fixed plate 27 to rotate back, so that the turntable 11 can be rotated more labor-saving.

[0043] Example 2: Combination Figure 1 , Figure 3 , Figure 4 and Figure 7 Based on the embodiment 1, the present embodiment is further improved in that: a transmission mechanism for driving the turntable 11 to rotate is installed on the mounting plate 1, and the transmission mechanism includes a driving shaft 29 rotatably connected to the short side of one side of the mounting plate 1 and a handle 10 fixed to one end of the driving shaft 29. A mounting cavity is opened inside the mounting plate 1, and the rotating shaft 26 runs through the mounting cavity. The outer periphery of the rotating shaft 26 located inside the mounting cavity is sleeved with a driven bevel gear, and one end of the driving shaft 29 extends into the mounting cavity and is fixed with an active bevel gear meshing with the driven bevel gear. The diameter of the active bevel gear is larger than the diameter of the driven bevel gear, and the length of the handle 10 is larger than the diameter of the active bevel gear, so that the turntable 11 can be driven to rotate more conveniently and labor-savingly.

[0044] The implementation principle of this embodiment is: when the cutting part needs to be swung when cutting grass, the handle 10 can be held and pressed down, thereby driving the drive shaft 29 to rotate. After the drive shaft 29 rotates, it drives the rotating shaft 26 to rotate, thereby driving the turntable 11 to rotate, thereby achieving the purpose of driving the turntable 11 to rotate conveniently and labor-savingly.
