Description

Technical Field

[0001] This invention relates to the field of harvester technology, and more specifically to a cotton field fennel harvester for cotton intercropping with fennel. Background Technology

[0002] Fennel is a herbaceous plant belonging to the genus Fennel in the family Apiaceae. It flowers in early summer and produces 8-9 woody follicles that are whorled in a star-like pattern. It has a strong aroma and can be used as a spice, condiment, and for medicinal purposes. Its dried fruit of the same name is one of the seasonings used in Chinese cuisine and cooking in Southeast Asia. It is an evergreen tree that grows in humid, warm, and semi-shaded environments and can grow up to 20 meters tall.

[0003] The shortcomings of existing technology: In order to increase crop yield, farmers usually intercrop fennel between cotton and fennel. The growth of the two crops does not affect each other. However, when harvesting fennel, since there is one row of cotton and one row of fennel in the field, the existing harvester will harvest the cotton next to it when harvesting fennel. At this time, manual harvesting of fennel is required, which leads to low harvesting efficiency of fennel. To address this, we propose a cotton field fennel harvester for cotton intercropping with fennel. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cotton field fennel harvester for cotton intercropping with fennel, so as to solve the problems existing in the background art.

The feed hopper is rotatably connected to a rotating column fixed at its lower end. A rotating rod is rotatably connected inside the mounting arm. The cutting blade is mounted on the circumferential surface of the rotating rod. A cutting motor is mounted at the lower end of the feed hopper. A drive shaft is mounted at the output end of the cutting motor. A driven shaft is rotatably connected to the rotating column and the mounting arm. The drive shaft is connected to one of the driven shafts via a first sprocket set. Each driven shaft has a meshing first gear mounted on its circumferential surface. The driven shaft is connected to the rotating rod via a second sprocket set. The rotating rods are connected to each other via a third sprocket set.

[0006] The feeding mechanism includes a first connecting roller, a first feeding belt, a rotating shaft, a second connecting roller, and a second feeding belt. The first connecting roller is mounted on the circumferential surface of the rotating shaft, and the first feeding belt is connected between the first connecting rollers. The first feeding belt is located above the mounting arm. The rotating shaft is rotatably connected to the feeding bin. The second connecting roller is mounted on the circumferential surface of the rotating shaft, and the second feeding belt is connected between the second connecting rollers. The second feeding belt is located inside the feeding bin, and the end of the feeding bin away from the mounting arm is located above the collection box. Traction plates are mounted on the surfaces of both the first and second feeding belts.

[0007] Preferably, an adjusting motor is installed at the lower end of the mounting frame, a drive rod is installed at the output end of the adjusting motor, a first bidirectional threaded rod is rotatably connected inside the mounting frame, the first bidirectional threaded rod is threadedly connected to a threaded block installed at the lower end of the feeding bin, and the first bidirectional threaded rod is connected to the drive rod through a fourth sprocket set.

[0008] Preferably, a second gear is installed on each circumferential surface of the rotating column, a hydraulic cylinder is installed at the lower end of the feeding bin, a rack is installed at the output end of the hydraulic cylinder, and the rack meshes with the second gear.

[0009] Preferably, the drive assembly includes a mounting plate, a slide bar, a mounting platform, a rotating frame, a drive roller, and a driven wheel. A pair of mounting plates are mounted on the lower end of the chassis, the slide bar is mounted between the mounting plates, the mounting platform and the rotating frame are mounted on the circumferential surface of the slide bar, the drive roller is mounted on the lower end of the mounting platform, and the driven wheel is rotatably connected inside the rotating frame.

[0010] Preferably, a connecting rod is connected between the mounting platform and the rotating frame, and a second bidirectional threaded rod is rotatably connected inside the mounting plate, with the second bidirectional threaded rod being threadedly connected to the connecting rod.

[0011] Preferably, the first bidirectional threaded rod and the second bidirectional threaded rod have the same pitch, and the first bidirectional threaded rod and the second bidirectional threaded rod are connected by a fifth sprocket set.

[0012] Preferably, a support frame is installed on the upper end of the chassis, and a driver's cab is provided on the upper end of the support frame. The driver's cab is used to control the operation of the equipment, and ladders are installed on the surface of the chassis and the support frame.

[0013] Preferably, a conveyor belt is connected between the rotating rollers rotatably connected inside the collection box, a support plate is fixedly connected inside the collection box, the support plate is located inside the conveyor belt, the support plate is slidably connected to the conveyor belt, and a box door is rotatably connected inside the collection box.

[0014] The technical effects and advantages of this invention are as follows:

[0015] 1. This invention pre-measures the planting spacing of two rows of fennel in a field. Then, by adjusting the spacing of the two feeding bins on the adjusting frame, the center-to-center distance between the feeding bins matches the center-to-center distance of the two rows of fennel. Since each set of mounting arms is symmetrically installed on the feeding bins, the extension angle of the mounting arms can be adjusted to cover the width of each row of fennel. After controlling the rotation of the cutting blades, the equipment moves forward, cutting the fennel. The harvested fennel is then pulled into the harvest bin by the first feeding belt, and finally transported to the collection box by the second feeding belt, completing the harvest. Simultaneously, by setting the distance and angle of the cutting blades, the harvesting process avoids cotton crops interspersed with fennel, achieving efficient fennel harvesting in cotton-fennel intercropped fields while minimizing the impact on surrounding cotton crops.

[0016] 2. This invention allows the drive roller and driven roller to adjust their positions simultaneously when the spacing of the feeding bin is adjusted. Furthermore, the first and second bidirectional threaded rods have the same pitch, and the pair of sprockets in the fifth sprocket set are also the same size. This ensures that when the feeding bin is adjusted left or right, the drive roller and driven roller adjust their positions simultaneously with the feeding bin, keeping the feeding bin aligned with the drive roller and driven roller. Consequently, when the front cutting blade harvests fennel after being positioned correctly, the rear drive roller and driven roller can avoid crushing the cotton crops in the middle and on both sides.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cotton field fennel harvester for cotton intercropping with fennel involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1-10As shown, in one embodiment, a cotton-fennel harvester for cotton intercropping with fennel is proposed, including a chassis 1, a drive assembly 2 mounted on the lower end of the chassis 1, a collection box 3 mounted on the upper end of the chassis 1, and a mounting frame 101 mounted between the chassis 1 and the collection box 3. A harvesting assembly 4 is provided on the surface of the mounting frame 101, and the harvesting assembly 4 includes an adaptive cutting mechanism 41 and a feeding mechanism 42. The adaptive cutting mechanism 41 includes an adjusting frame 411, a feeding bin 412, mounting arms 414, and a cutting blade 417. The adjusting frame 411 is mounted on the surface of the mounting frame 101, and the lower end of the feeding bin 412 is slidably connected to the circumferential surface of the adjusting frame 411 via a slider 413. A pair of mounting arms 414 are connected by a rotating column 41 fixed at the lower end. 5. Rotary connection is made inside the feeding bin 412. Rotary rod 416 is rotatably connected inside the mounting arm 414. Cutting blade 417 is installed on the circumferential surface of rotating rod 416. Cutting motor 418 is installed at the lower end of feeding bin 412. Drive shaft 419 is installed at the output end of cutting motor 418. Driven shaft 4110 is rotatably connected inside rotating column 415 and mounting arm 414. Drive shaft 419 is connected to one of driven shafts 4110 through a first sprocket set 4111. First gears 4112 that mesh with each other are installed on the circumferential surface of driven shaft 4110. Driven shaft 4110 is connected to rotating rod 416 through a second sprocket set 4113. Rotating rods 416 are connected to each other through a third sprocket set 4114.

[0032] The feeding mechanism 42 includes a first connecting roller 421, a first feeding belt 422, a rotating shaft 423, a second connecting roller 424, and a second feeding belt 425. The first connecting roller 421 is mounted on the circumferential surface of the rotating rod 416. The first feeding belt 422 is connected between the first connecting rollers 421 and is located above the mounting arm 414. The rotating shaft 423 is rotatably connected inside the feeding bin 412. The second connecting roller 424 is mounted on the circumferential surface of the rotating shaft 423 and is connected between the second connecting rollers 424. The second feeding belt 425 is located inside the feeding bin 412. The end of the feeding bin 412 away from the mounting arm 414 is located above the collection box 3. Traction plates 426 are mounted on the surfaces of both the first feeding belt 422 and the second feeding belt 425.

[0033] In practical application, this invention involves pre-measuring the planting spacing of two rows of fennel in a field. Then, the spacing between the two feeding bins 412 on the adjusting frame 411 can be adjusted so that the center-to-center distance between the feeding bins 412 matches the center-to-center distance between the two rows of fennel. Since each set of mounting arms 414 is symmetrically installed on the feeding bins 412, the unfolding angle of the mounting arms 414 can be adjusted to cover the width of each row of planted fennel. Subsequently, by controlling the cutting motor 418, the cutting motor 418 drives the drive shaft 419 to rotate. The drive shaft 419, through the action of the first sprocket set 4111, drives the driven shaft 4110 to rotate. Then, through the first gear 4112 meshing with each other on the circumference of the driven shaft 4110, each pair of adjacent driven shafts 4110 will rotate in the opposite direction. Under the action of the second sprocket set 4113, the driven shaft 4110 will drive the rotating rod 416 to rotate. At the same time, under the action of the third sprocket set 4114, multiple rotating rods 416 can rotate simultaneously, thereby driving multiple cutting blades 417 to rotate. Since the multiple cutting blades 417 are divided into four rows, with each two rows forming a group, each group of cutting blades 417 rotates backward. When the equipment moves forward through the drive component 2, the cutting blades 417 will contact the root of the fennel, achieving the cutting of the fennel while pulling it backward.

[0034] Furthermore, when the rotating rod 416 rotates, it will drive the first feeding belt 422 to rotate under the action of the first connecting roller 421. After the fennel is cut, it will be pushed backward by the action of the first feeding belt 422 and the traction plate 426, so that it is pushed to the feeding bin 412. At this time, by controlling the rotation of the rotating shaft 423, the rotating shaft 423 will drive the second feeding belt 425 to rotate through the second connecting roller 424. Then, through the traction plate 426 installed on the second feeding belt 425, the cut fennel can be transported backward to the collection box 3, thus completing the collection of fennel. While harvesting fennel, by setting the distance and angle of the cutting blade 417, the cotton crops between the fennel can be avoided, thus achieving the effect of efficient fennel harvesting in cotton fields where fennel is intercropped with cotton.

[0035] In one embodiment of the present invention, since each group of cutting blades 417 has a height difference, no interference will occur when the angle of the cutting blades 417 is adjusted.

[0036] like Figure 6-8As shown, in a preferred embodiment of the present invention, an adjusting motor 4115 is installed at the lower end of the mounting frame 101, and a drive rod 4116 is installed at the output end of the adjusting motor 4115. A first bidirectional threaded rod 4117 is rotatably connected inside the mounting frame 101. The first bidirectional threaded rod 4117 is threadedly connected to a threaded block 4118 installed at the lower end of the feeding bin 412. The first bidirectional threaded rod 4117 and the drive rod 4116 are connected by a fourth sprocket set 4119.

[0037] In practical application, by controlling the operation of the regulating motor 4115, the regulating motor 4115 will drive the drive rod 4116 to rotate. The drive rod 4116 will drive the first bidirectional threaded rod 4117 to rotate through the action of the fourth sprocket group 4119. The first bidirectional threaded rod 4117 will drive the feeding bin 412 to move left and right through the threaded block 4118, thereby achieving the effect of controlling the adjustable spacing between the feeding bins 412, so that it avoids the cotton crops in the middle when harvesting fennel.

[0038] like Figure 7-9 As shown, in another preferred embodiment of the present invention, a second gear 4120 is installed on the circumferential surface of the rotating column 415, a hydraulic cylinder 4121 is installed at the lower end of the feeding bin 412, and a rack 4122 is installed at the output end of the hydraulic cylinder 4121, which meshes with the second gear 4120.

[0039] In practical application, by controlling the operation of the hydraulic cylinder 4121, the hydraulic cylinder 4121 will drive the rack 4122 to move back and forth. When the rack 4122 moves, it will drive the second gears 4120 on both sides to rotate in opposite directions, thereby driving the mounting arm 414 to rotate. This achieves the effect of adjusting the angle of each set of cutting blades 417 under the mounting arm 414, so that it can be adapted to the width of different fennel crops.

[0040] like Figure 11 and 12 As shown, in another preferred embodiment of the present invention, the drive assembly 2 includes a mounting plate 201, a slide bar 202, a mounting platform 203, a rotating frame 204, a drive roller 205, and a driven wheel 206. A pair of mounting plates 201 are mounted on the lower end of the chassis 1, the slide bar 202 is mounted between the mounting plates 201, the mounting platform 203 and the rotating frame 204 are mounted on the circumferential surface of the slide bar 202, the drive roller 205 is mounted on the lower end of the mounting platform 203, and the driven wheel 206 is rotatably connected to the rotating frame 204.

[0041] In practical application, by adjusting the position of the mounting platform 203 and the rotating frame 204 on the circumferential surface of the slide bar 202, the distance between each set of drive rollers 205 and driven rollers 206 can be adjusted so that the drive rollers 205 and driven rollers 206 on both sides can be aligned with the front and rear positions of the feeding bins 412 on both sides. When the cutting blade 417 is harvesting fennel in front, the drive rollers 205 and driven rollers 206 at the rear can just crush the empty ground after the fennel is harvested, avoiding the drive rollers 205 and driven rollers 206 from crushing other crops.

[0042] like Figure 11 and 12 As shown, in another preferred embodiment of the present invention, a connecting rod 207 is connected between the mounting platform 203 and the rotating frame 204, and a second bidirectional threaded rod 208 is rotatably connected inside the mounting plate 201, and the second bidirectional threaded rod 208 is threadedly connected to the connecting rod 207.

[0043] In practical application, the driving roller 205 and the driven roller 206 can be aligned front to back by the connecting rod 207. When the second bidirectional threaded rod 208 is rotated, it will drive the connecting rod 207 to move left and right, thereby achieving the effect of controlling the positions of the driving roller 205 and the driven roller 206 on both sides, so that they can be aligned with the front and back positions of the feeding bin 412.

[0044] like Figure 11 and 12 As shown, in another preferred embodiment of the present invention, the first bidirectional threaded rod 4117 and the second bidirectional threaded rod 208 have the same pitch, and the first bidirectional threaded rod 4117 and the second bidirectional threaded rod 208 are connected by a fifth sprocket set 209.

[0045] In practical application, when the first bidirectional threaded rod 4117 rotates, the distance between the feeding bins 412 can be adjusted. Simultaneously, under the action of the fifth sprocket set 209, the second bidirectional threaded rod 208 can be rotated. This allows the driving roller 205 and driven wheel 206 to adjust their positions simultaneously when the feeding bins 412 adjust their distance. Furthermore, the first bidirectional threaded rod 4117 and the second bidirectional threaded rod 208 have the same pitch, and the pair of sprockets in the fifth sprocket set 209 also have the same size. This ensures that when the feeding bins 412 are adjusted left and right, the driving roller 205 and driven wheel 206 can adjust their positions simultaneously with the feeding bins 412. This keeps the feeding bins 412 and the driving roller 205 and driven wheel 206 in a front-to-back aligned state. Consequently, when the front cutting blade 417 is harvesting fennel after adjusting its position, the rear driving roller 205 and driven wheel 206 can avoid the cotton crops in the middle and on both sides, preventing them from being crushed.

[0046] like Figure 1 and 2 As shown, in another preferred embodiment of the present invention, a support frame 5 is installed on the upper end of the chassis 1, and a driver's cab 501 is provided on the upper end of the support frame 5. The driver's cab 501 is used to control the operation of the equipment, and a ladder 502 is installed on the surface of the chassis 1 and the support frame 5.

[0047] In practical applications, the escalator 502 allows workers to access the high-level driver's cab 501 to operate the equipment. The driver's cab 501 provides a good view and allows real-time observation of the position of the cutting blade 417. This enables real-time adjustments during operation, thereby reducing the impact on cotton crops during fennel harvesting.

[0048] like Figure 3 and 4 As shown, in another preferred embodiment of the present invention, a conveyor belt 302 is connected between the rotating rollers 301 rotatably connected inside the collection box 3, a support plate 303 is fixedly connected inside the collection box 3, the support plate 303 is located inside the conveyor belt 302, the support plate 303 is slidably connected to the conveyor belt 302, and a box door 304 is rotatably connected inside the collection box 3.

[0049] In practical application, after the fennel is cut and harvested and enters the collection box 3, the conveyor belt 302 is rotated to transport the fennel to the rear, preventing it from accumulating in front of the collection box 3. At the same time, the support plate 303 supports the conveyor belt 302 to prevent it from sinking. When unloading is completed, the box door 304 is opened, and the rotation of the conveyor belt 302 can assist in unloading.

[0050] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

[0051] Secondly: The accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.
