Description

Technical Field

[0001] The present invention relates to the technical field of pepper harvesting equipment, and more specifically, to a small mountain pepper harvester. Background Art

[0002] In the pepper planting industry, the efficiency and quality of the harvesting link have a crucial impact on the overall economic benefits. Especially in complex terrain areas such as mountains, traditional pepper harvesting methods face many problems.

[0003] Currently, the common pepper harvesters on the market are mostly designed for open terrains such as plains. They are large in size and complex in structure, and it is difficult to adapt to the narrow and undulating terrain conditions in mountains. When operating in mountains, such harvesters are prone to problems such as difficult passage and inability to turn flexibly, resulting in low operation efficiency and even inability to work properly.

[0004] In addition, the impurity removal technology of existing harvesters is generally relatively single. During the pepper harvesting process, the harvested peppers are often mixed with a large amount of impurities such as stalks, pepper leaves, and sand and stones. Traditional impurity removal mechanisms can only perform simple primary impurity removal and cannot effectively separate peppers from various impurities. For example, common impurity removal methods may only be able to remove some larger stalks, and it is difficult to clean impurities such as pepper leaves and fine sand and stones, resulting in a high impurity content in the harvested peppers, seriously affecting the quality of peppers and subsequent processing and sales.

[0005] For mountain pepper growers, due to the lack of applicable harvesting equipment, most still rely on manual picking, which not only consumes a large amount of manpower, material resources and time, but also the labor cost is increasing year by year. At the same time, manual picking has low efficiency and cannot meet the needs of the pepper centralized harvesting period, resulting in losses of some peppers due to failure to pick them in time.

[0006] If a small mountain pepper harvester that can effectively separate and clean impurities such as stalks, pepper leaves, and sand and stones and can effectively reduce the breakage rate of peppers during the picking process can be provided, then mechanized harvesting of peppers can be carried out in the hilly mountainous areas of Guizhou.

One end of it is connected to the picking table 1, and the other end realizes angle adjustment through the lifting oil cylinder 11. Under the action of the lifting oil cylinder 11, the first-stage conveyor belt assembly 202 can adjust the angle with the ground. When the materials knocked down by the picking table 1 are thrown onto the first-stage conveyor belt assembly 202, the first-stage conveyor belt assembly 202 relies on its own transmission structure to convey the materials from the low end to the high end and convey them to the feeding port of the cleaning and separating device 5, realizing the primary lifting and transfer of the materials.

[0045] The picking table 1 includes a dividing board 101, a pressing board 102, a spring-tooth roller 103, a first hydraulic motor 104, a support frame 105, a second hydraulic motor 106, a profiling ground roller 107, and an inclined side conveyor belt 108. The support frame 105 is fixedly connected to the outer shell of the first-stage conveyor belt assembly 202.

[0048] In this embodiment, when the picking table 1 works, the dividing board 101 first gathers and separates the pepper plants to be picked, so that the plants enter the picking area orderly. The pressing board 102 will press down the too-high pepper plants to a suitable height for subsequent processing. Then, the hydraulic motor 104 drives the sprocket chain to drive the elastic tooth drum 103 to rotate at a high speed. The flexible elastic teeth 10322 on the elastic tooth drum 103 strike the pepper plants, knocking off the peppers, stems, pepper leaves, etc. These knocked-off materials are thrown to the rear first-stage lifting device 2 and the inclined side conveyor belt 108 under the action of the clockwise rotation of the elastic tooth drum 103. The inclined side conveyor belt 108 is controlled by the hydraulic motor 106 to operate, and transfers the materials on the conveyor belt to the first-stage lifting device 2 to complete the preliminary conveyance of the picked materials.

[0049] The cleaning and separating device 5 includes a fixing frame 504, a first-stage impurity cleaning mechanism 501, a second-stage impurity cleaning mechanism 502, a funnel 503, and a stem discharge port 505. The fixing frame 504 is fixed on the frame 8. The first-stage impurity cleaning mechanism 501 is arranged on the fixing frame 504. One end of the fixing frame 504 is provided with a downwardly inclined stem discharge port 505. The first-stage impurity cleaning mechanism 501 is inclined and the included angle with the horizontal plane is - degrees. The stem discharge port 505 is arranged below the high end of the first-stage impurity cleaning mechanism 501. The second-stage impurity cleaning mechanism 502 is arranged on the lower side of the first-stage impurity cleaning mechanism 501.

[0050] The primary impurity removal mechanism 501 includes a second separation wheel set 5021 and a support plate 5012. The support plate 5012 is fixed to both sides of the fixed frame 504. The first separation wheel set 5011 includes a crushing wheel composed of a plurality of separation wheels fixed on a rotating shaft. The rotating shaft is connected to the support plate 5012 through bearings. One end of the rotating shaft is fixed with a second sprocket, and the second sprocket is connected by a second chain drive. The other end of one of the rotating shafts at one end is fixedly connected to the output shaft of the motor, and the motor is fixed to the support plate 5012.

[0051] The secondary impurity removal mechanism 502 includes a second separation wheel set 5021 and a mounting plate 5022. The second separation wheel set 5021 is composed of a second separation wheel formed by fixing a plurality of rotating toothed plates 50211 on a circular shaft 50212. The circumferential surface of the second separation wheel is an uneven curved surface. The circular shaft 50212 is connected to the mounting plate 5022 through bearings.

[0052] The fixed frame 504 is of a frame type. The gap between the second separation wheels is smaller than the size of the vast majority of peppers, and the gap between the second separation wheels allows crushed soil, straw, etc. to pass through.

[0053] In this embodiment, the primary impurity removal mechanism 501 utilizes the characteristics of the stems having many branches and a longer length. The motor drives the first separation wheel set 5011 to rotate. During the rotation of the separation wheels of the first separation wheel set 5011, materials such as peppers, stems, and pepper leaves are agitated. The stems are separated due to their own characteristics and move towards the stem discharge port 505, while the peppers and pepper leaves fall from the gap of the first separation wheel set 5011 to the secondary impurity removal mechanism 502. The second separation wheel set 5021 of the secondary impurity removal mechanism 502 is composed of rotating toothed plates 50211, and the circumferential surface is uneven. When it rotates, it further separates the peppers from the pepper leaves, sand, and other impurities. The pepper leaves and sand fall from the gap to the field, while the peppers move towards the funnel 503 and fall into the secondary elevating device 6, so that the peppers falling into the secondary elevating device 6 are pure peppers.

The feed baffle 602 fixes the housing of the secondary conveyor belt assembly 601. The upper end of the secondary conveyor belt assembly 601 is arranged corresponding to one side of the upper end of the receiving box 7.

[0055] In this embodiment, the secondary elevating device 6 is driven by a servo motor. The housing of the secondary conveyor belt assembly 601 is fixed to the frame 8 through the secondary connecting frame 604. When the peppers processed by the cleaning and separating device 5 fall to the feed baffle 602 of the secondary conveyor belt assembly 601, the secondary conveyor belt assembly 601 operates under the drive of the servo motor, conveying the peppers from the low end to the high end and transporting them to the inlet of the receiving box 7, realizing the re - elevation of the peppers and the transportation before final collection. The feed baffle 602 is used to prevent the peppers from splashing and achieve the collection of the peppers.

[0056] The receiving box 7 includes a support rod 703, a second oil cylinder 702, and a box body 701. The upper ends of the symmetric support rods 703 are rotatably connected to one side of the upper part of the receiving box 7.

The end of the telescopic rod of the second oil cylinder 702 is rotatably connected to one side of the upper part of the box body 701. A notch is provided on one side of the box body 701 corresponding to the outlet of the secondary elevating device 6 to facilitate the entry of materials.

[0057] In this embodiment, one side of the upper part of the receiving box 7 is rotatably connected to the frame 8 through the support rod 703, and its tilt angle is controlled by the second oil cylinder 702. When the secondary elevating device 6 conveys the peppers, a notch is provided on the box body 701 of the receiving box 7 corresponding to the outlet of the secondary elevating device 6 to facilitate the entry of materials. When the receiving box 7 needs to unload materials, by controlling the telescopic movement of the telescopic rod of the second oil cylinder 702, the tilt angle of the receiving box 7 is changed to unload the collected peppers.

[0058] The usage method of the present invention is as follows: When using the small - scale mountain pepper harvester for operation, the operator enters the cab 3, starts the engine 4, and controls the device to move to the area where peppers need to be picked. The driver starts the lifting oil cylinder 11 and adjusts the height of the picking table 1 by controlling the telescopic movement of the telescopic rod of the lifting oil cylinder 11. According to the actual growth height of the pepper plants, the picking table 1 is adjusted to a suitable position so that the subsequent picking operation can be carried out smoothly, ensuring that peppers can be effectively picked and the picking effect will not be affected by the picking table 1 being too high or too low;

[0059] After the height of the picking table 1 is adjusted, the driver starts the traveling device 10 and drives the harvester to move, ensuring that the crawler belts on both sides of the traveling device 10 completely enter the furrows, and at the same time ensuring that the chili plants to be harvested are just located in the middle of the picking table. Such an operation not only helps to improve the picking rate of chili peppers, but also avoids damage to the chili plants in the harvesting area caused by the crawler belts during the traveling process, such as being crushed or knocked down.

[0060] When the harvester reaches the designated position and all the preparatory work is completed, the operator selects an appropriate traveling speed to start the harvesting operation according to the actual conditions such as the growth status of the chili peppers in the harvesting area and the terrain conditions. During the harvesting process, the dividing board 101 will gather the chili plants to be picked and separate the chili plants on both sides, preparing for the subsequent picking actions. Then, the pressing board 102 presses down the too-high chili plants to a suitable height so that the spring-tooth drum 103 can better contact the chili plants. At this time, the spring-tooth drum 103 rotates at a high speed driven by the hydraulic motor 104, knocking down the chili peppers, stems, pepper leaves, etc. on the fed chili plants. The knocked-down materials are driven clockwise by the spring-tooth drum 103 and thrown onto the rear first-stage elevating device 2 and the inclined-side conveyor belt 108. The inclined-side conveyor belt 108 operates driven by the hydraulic motor 106, transporting the materials on the conveyor belt to the first-stage elevating device 2, and the first-stage elevating device 2 then transports the materials to the first-stage impurity-removing mechanism 501 of the cleaning and separating device 5;

[0061] In the cleaning and separating device 5, the first-stage impurity-removing mechanism 501 first separates the stems from the chili peppers, pepper leaves, etc. by utilizing the characteristics of the stems having many branches and a longer length. The stems are transported to the stem discharge port 505 and discharged, while the chili peppers and pepper leaves fall through the gaps to the second-stage impurity-removing mechanism 502. The second-stage impurity-removing mechanism 502 further separates the chili peppers from the pepper leaves, sand and other impurities. The pepper leaves and sand fall through the gaps to the field, and the chili peppers move towards the funnel 503 and fall onto the second-stage elevating device 6. Finally, only the chili peppers fall along the funnel 503 onto the second-stage elevating device 6. The second-stage elevating device 6 is driven by a steering gear to transport the chili peppers after impurity removal to the receiving box 7, completing the harvesting operation of the chili peppers;

[0062] When the receiving box 7 is filled with chili peppers or the harvesting operation is completed, by operating the control device, the second oil cylinder 702 is started to make the telescopic rod of the second oil cylinder 702 stretch and retract, changing the inclination angle of the receiving box 7 to unload the chili peppers in the receiving box 7.

[0063] The above only discloses the specific embodiments of the present invention. However, the present invention is not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
