Description

Technical Field

[0001] This invention relates to the field of rapeseed harvesting technology, and in particular to an orderly harvesting machine for rapeseed in greenhouses. Background Technology

[0002] Greenhouses provide excellent environmental conditions for rapeseed growth, allowing for multiple harvests per year and enabling large-scale promotion. However, the main constraint on large-scale rapeseed cultivation is the manual harvesting method, which is labor-intensive and costly. At maturity, a single worker can harvest at most 2-3 mu (approximately 0.33-0.2 hectares) per day; for a thousand-mu (approximately 667 hectares) plantation, it is impossible to temporarily hire a team of hundreds. Therefore, for the industrialized production of rapeseed, there is an urgent need to solve the problem of mechanized harvesting.

[0003] Currently, some small harvesting devices have appeared on the market, which can replace manual harvesting and are more efficient. However, most rapeseed harvesting equipment mainly uses cutting blades to cut the rapeseed from the plant, which is relatively simple and direct. For example, common reciprocating cutters simply cut the stem of the rapeseed without any subsequent collection and sorting device, and the cut rapeseed will naturally pile up after being cut. Since the shape and location of rapeseed may vary, the cut rapeseed will fall in all directions. Some rapeseed harvesting equipment focuses more on harvesting efficiency and does not pay enough attention to the post-harvest sorting process. It does not have a special component designed to neatly arrange the rapeseed, so the rapeseed cannot be sorted in time after being harvested and can only be piled up in a scattered state, which is not conducive to subsequent collection, packaging, and transportation processes.

[0004] Based on the above situation, we propose an orderly harvesting machine for greenhouse vegetable shoots to solve the above problems. Summary of the Invention

[0005] This invention provides an orderly harvesting machine for greenhouse vegetable shoots to solve the problem in the prior art that it is inconvenient to arrange the harvested vegetable shoots in an orderly manner.

[0006] The technical problem solved by this invention is achieved by the following technical solution:

[0007] A greenhouse vegetable shoot harvester includes a harvesting frame with a cutting blade, multiple sets of separating components, a first-direction conveyor belt mounted on the harvesting frame, openable baffles, and a second-direction conveyor belt mounted on the harvesting frame. The multiple sets of separating components are movably connected to a frame installed at the front end of the harvesting frame, used to gather whole vegetable shoots towards the center. The first-direction conveyor belt transports the vegetable shoots cut by the cutting blade, and has multiple sets of separating plates. The openable baffles are located between the output end of the separating components and the cutting blade, used to limit the cut vegetable shoots and cause them to tilt onto the first-direction conveyor belt for transport. The number of openable baffles is multiple, corresponding one-to-one with the multiple sets of separating components and multiple sets of separating plates. The second-direction conveyor belt is located at the output end of the first-direction conveyor belt, and there are two second-direction conveyor belts with opposite transport directions, used to orderly transport the vegetable shoots to collection boxes on both sides of the harvesting frame.

[0008] Preferably, the separating component includes two opposing separating plates arranged in a "V" shape. The frame is slidably connected with mounting components corresponding to the separating components. The top ends of the two separating plates are rotatably connected to the mounting components, and the upper ends of the two separating plates are provided with a first gear located inside the mounting component. The two first gears mesh with each other.

[0009] Preferably, the mounting component is provided with a first locking member extending to the upper end of the frame, and the first locking member is provided with a first abutment plate.

[0010] Preferably, one of the first gears is provided with an adjusting rod extending to the upper end of the frame, and the adjusting rod is provided with an indicator arrow.

[0011] Preferably, the openable baffle includes two oppositely arranged movable baffles, both of which are rotatably connected to the mounting component, and an arc-shaped spring connects the openable baffle to the mounting component.

[0012] Preferably, the partition plate is slidably connected to the bracket that is fixedly connected to the harvester, and the partition plate is threadedly connected to a second locking member, which is provided with a second abutment plate.

[0013] Preferably, the first directional conveyor belt is driven by a first drive pair, the first drive pair includes at least two sets of first rotating shafts, at least two of the first rotating shafts are arranged sequentially at intervals on the transmission path of the first directional conveyor belt, and adjacent first rotating shafts are connected by belts, and the harvester is provided with a first motor whose output end is connected to one of the first rotating shafts.

[0014] Preferably, the second direction conveyor belt is driven by a second drive pair, the second drive pair includes at least two second shafts arranged sequentially at intervals on the transmission path of the second direction conveyor belt, two adjacent second shafts on the same second direction conveyor belt are connected by belt drive, and two adjacent second shafts on two second direction conveyor belts are provided with a second gear, and the two second gears mesh with each other. The harvester is provided with a second motor whose output end is connected to one of the second shafts.

[0015] The beneficial effects of this invention are:

[0016] First, the separating device gathers each vegetable plant towards the center, making the stems and leaves of the rapeseed more compact. This allows the cutting blade to cut the base of the rapeseed more precisely. Then, the openable baffle limits the cut rapeseed, causing it to tilt onto the first direction conveyor belt and be transported to the second direction conveyor belt. After that, it is transported in the opposite direction again, collecting the harvested rapeseed according to the same leaf direction into the collection boxes on both sides for subsequent packaging and other processes, making it more convenient.

[0017] 2. To address the planting gaps between rapeseed shoots, the positions of the installation components and partitions are adjusted to ensure that the rapeseed shoots are arranged neatly, preventing them from being squeezed, tangled, or piled up during transportation. This also ensures that the rapeseed shoots are transported quickly and in an orderly manner, reducing congestion during transportation and thus improving transportation efficiency.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0029] Reference Figures 1-8As shown, a greenhouse rapeseed harvester includes a harvesting frame 1 with a cutting blade 11 and wheels underneath for movement within the greenhouse ridges. It can be towed by agricultural vehicles. The harvesting frame 1 also includes multiple sets of separating components 2, each corresponding to a row of planted rapeseed. These components are movably connected to a frame 12 installed at the front end of the harvesting frame 1, used to gather the entire rapeseed plant towards the center. During harvesting, the harvesting frame 1 drives the separating components 2 to gather the rapeseed inwards. As the rapeseed contracts inwards, the stems and leaves... The cutting blades 11 are arranged more compactly, allowing for more precise cutting of the base of the rapeseed shoots and preventing mechanical damage caused by collisions or external pulling before harvesting. A first-direction conveyor belt 3 is also installed on the harvesting frame 1 to transport the rapeseed shoots cut by the cutting blades 11. The harvested rapeseed shoots fall onto the first-direction conveyor belt 3 and are transported backward. The first-direction conveyor belt 3 is equipped with multiple sets of partition plates 31, which divide the belt into multiple conveying channels, allowing each row of cut rapeseed shoots to fall onto the first-direction conveyor belt separately. When the vegetable shoots are fed onto conveyor belt 3, they can be arranged neatly, reducing disorder. Furthermore, to ensure the cut vegetable shoots fall directly onto the first-direction conveyor belt 3, an openable baffle 4 is provided between the output end of the separator 2 and the cutting blade 11. This baffle limits the cut vegetable shoots, causing them to fall onto the first-direction conveyor belt 3 for transport. Multiple sets of openable baffles 4 are provided, each corresponding to a set of separators 2 and multiple sets of partitions 31. After the cutting blade 11 cuts the vegetable shoots, the openable baffles 4 limit their movement, preventing them from falling towards the separators 2, but instead directing them towards the first-direction conveyor belt 3. The roots of the rapeseed shoots face the input end of the first directional conveyor belt 3, allowing them to fall directly into the conveying channel. At the output end of the first directional conveyor belt 3, there are two second directional conveyor belts 5, each with opposite conveying directions. After the rapeseed shoots fall from the first directional conveyor belt 3 onto the second directional conveyor belt 5, their orientation remains unchanged, with the roots still facing the input end of the directional conveyor belt. This keeps the rapeseed shoots in an orderly manner, allowing them to be transported systematically to the collection boxes on both sides of the harvesting rack 1. This facilitates subsequent unified collection, packaging, and other processing, reducing labor intensity.

[0030] Reference Figure 5 Figure 7As shown, further, the separating component 2 includes two opposing separating plates 21, which are arranged in a "V" shape. The larger opening of the "V"-shaped separating plate 21 faces the rapeseed, making it easier for the rapeseed to enter the separating component 2. As the slope of the separating plate 21 gradually narrows inward, the two slopes of the two separating plates 21 guide and restrict the movement direction of the rapeseed, allowing the rapeseed to neatly gather towards the center. The frame 12 is slidably connected with mounting components 22 corresponding to the separating component 2. The tops of the two separating plates 21 are rotatably connected to the mounting components 22, and the upper ends of the two separating plates 21 are provided with first gears 23 located inside the mounting components 22. The two first gears 23 mesh with each other. The opening size of the separating component 2 can be adjusted for rapeseed of different plant sizes. Since the size and shape of the rapeseed will change at different growth stages, in the seedling stage, the rapeseed plant is smaller. At this time, the opening of the separating component 2 can be reduced so that the separating component 2 can gently and tightly gather the rapeseed seedlings. It helps protect the seedling's growth point and tender leaves, preventing damage to the seedling during the gathering process. As the rapeseed grows, the plant gradually grows larger and thicker, and the opening of the separation plate 21 can be increased accordingly to accommodate the increase in the volume of the rapeseed, ensuring that the rapeseed can be effectively gathered without hindering the gathering of the rapeseed due to an excessively small opening, or breaking the stem of the rapeseed due to forced gathering. By adjusting the angle of one of the separation plates 21, the meshing action of the first gear 23 drives the other first gear 23 to rotate, so that the two separation plates 21 can be adjusted synchronously.

[0031] One of the first gears 23 is provided with an adjusting rod 203 extending to the upper end of the frame 12. The separation plate 21 is prevented from swinging randomly between the two separation plates 21 by the friction between the separation plate 21 and the mounting part 22. When it is necessary to expand the opening angle of the separation part 2, the adjusting rod 203 is rotated so that the force of the adjusting rod 203 driving one of the first gears 23 to rotate is greater than the friction force between the separation plate 21 and the mounting part 22. The opening size of the separation part 2 can be adjusted. The adjusting rod 203 is provided with an indicator arrow 204, and the direction of the indicator arrow 204 can be observed. By rotating multiple adjusting rods 203 to approximately the same position, the opening sizes of multiple separation parts 2 are basically the same.

[0032] To adapt the separator 2 to the width between different furrows, refer to Figure 5 As shown, the mounting component 22 is further provided with a first locking component 201 extending to the upper end of the frame 12, and the first locking component 201 is provided with a first abutting plate 202. According to the width of the ridge, after adjusting the separating component 2 to the position corresponding to the rapeseed through the mounting component 22, the first locking component 201 is rotated so that the first abutting plate 202 is in close contact with the upper end surface of the frame 12 to fix the mounting component 22.

[0033] Furthermore, the openable baffle 4 includes two opposing movable baffles 41, both of which are rotatably connected to the mounting member 22. An arc-shaped spring 42 connects the openable baffle 4 to the mounting member 22. When the rapeseed shoots, gathered towards the center, are output through the output end of the separator 2, they will compress the two movable baffles 41. (Refer to...) Figure 6 As shown, the two movable baffles 41 are compressed by the two arc springs 42 and then opened. Once the rapeseed shoot passes through the movable baffles 41, the movable baffles 41 will be reset under the action of the arc springs 42, so that the two movable baffles 41 are on the same straight line. At this time, the root of the rapeseed shoot will come into contact with the cutting blade 11 and cut it off. Due to the blocking and limiting of the rapeseed shoot by the movable baffles 41, the rapeseed shoot cannot be tilted towards the separating part 2, but will only tilt towards the first direction conveyor belt 3.

[0034] In order to accommodate the adjustment of the spacing between multiple separating parts 2, the partition plate 31 is slidably connected to the hanging frame 13 which is fixedly connected to the harvesting frame 1, and the partition plate 31 is threadedly connected to the second locking member 301. The second locking member 301 is provided with a second abutment plate 302. After the position of the partition plate 31 is adjusted, the second locking member 301 is rotated to drive the second abutment plate 302 to make it tightly abut against the upper end of the hanging frame 13, thereby realizing the position adjustment and fixation of the partition plate 31.

[0035] Furthermore, the first direction conveyor belt 3 is driven by a first drive pair, which includes at least two sets of first rotating shafts 6. At least two first rotating shafts 6 are arranged sequentially at intervals on the transmission path of the first direction conveyor belt 3, and adjacent first rotating shafts 6 are connected by belts. The harvester frame 1 is provided with a first motor 61 whose output end is connected to one of the first rotating shafts 6. The first motor 61 drives one of the first rotating shafts 6 to rotate, and the belt drives the other first rotating shaft 6 to rotate, thereby realizing the operation of the first direction conveyor belt 3.

[0036] Further reference Figure 1As shown, the second directional conveyor belt 5 is driven by a second drive pair. The second drive pair includes at least two second rotating shafts 7 arranged sequentially at intervals on the transmission path of the second directional conveyor belt 5. Two adjacent second rotating shafts 7 on the same second directional conveyor belt 5 are connected by belt drive. Two adjacent second rotating shafts 7 on the two second directional conveyor belts 5 are provided with second gears 71, and the two second gears 71 mesh with each other. The harvesting frame 1 is provided with a second motor 72 whose output end is connected to one of the second rotating shafts 7. When the second motor 72 drives one of the second rotating shafts 7 to rotate, the meshing action of the second gears 71 will drive the second rotating shaft 7 on the other second directional conveyor belt 5 to move in the opposite direction, thereby realizing that the conveying directions of the two second directional conveyor belts 5 are opposite, and the rapeseed on the first directional conveyor belt 3 is conveyed to both sides of the harvesting frame 1 for subsequent collection and processing.
