Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a camellia fruit collection device for camellia oil extraction. Background Technology

[0002] Camellia oleifera fruit is the fruit of the Camellia oleifera tree, one of my country's important woody oil crops. The ripe fruit can be used to extract camellia oil. Camellia oil is of excellent quality, with high nutritional and economic value; therefore, harvesting camellia oleifera fruit is a crucial step in the camellia oil production process. Camellia oleifera trees are mostly planted in hilly and mountainous areas, with varying tree heights. The ripe fruit easily falls naturally and scatters on the ground.

[0003] Currently, the main methods for collecting camellia oleifera fruits are manual picking and manual-assisted collection. This often involves manually knocking the branches to make the fruits fall and then picking them up, or using simple collection devices to collect the fruits from the ground. The collected camellia oleifera fruits are then initially graded based on their size.

[0004] This type of method is greatly affected by terrain conditions, work intensity and fruit distribution in actual use. Collection and sorting are mostly done manually, resulting in low overall work efficiency and high labor intensity. It is difficult to meet the demand for efficient and continuous harvesting of camellia fruit during the concentrated ripening period.

[0005] To address the aforementioned issues, there is an urgent need for a camellia fruit collection device for camellia oil extraction. This device features an automated sorting structure that enables continuous preliminary grading based on fruit size during the harvesting process. This reduces manual labor, improves operational efficiency, and ensures the overall smoothness and stability of the camellia fruit harvesting and subsequent oil extraction process. Summary of the Invention

[0006] In response to the problems raised in the background art, the present invention provides a camellia fruit collection device for camellia oil extraction, which will be further described below.

[0007] A camellia fruit collecting device for camellia oil extraction includes a base with several rollers mounted on the bottom. A vehicle body is fixedly connected to the top of the base, and a receiving device is fixedly connected to the front end of the top of the vehicle body. Symmetrically distributed clamping members are slidably connected to the front end of the base, and a first spring is provided between the clamping members and the base. A sorting assembly is provided inside the vehicle body. A feeding member is fixedly connected to the bottom of the receiving device's interface, and a buffer member is slidably connected to the bottom of the feeding member. A second spring is provided between the buffer member and the bottom of the feeding member. A fixed frame is fixedly connected inside the vehicle body, and a cylinder is mounted on the fixed frame. A transmission frame is fixedly connected to the linkage output rod of the cylinder, and sliding frames are fixedly connected to both ends of the transmission frame. The sorting assembly includes a sieve roller slidably connected to the sliding frame. Three first collection boxes are correspondingly provided below the sieve roller, and a net is fixedly connected to the discharge port of each first collection box. A second collection box is installed at the rear of the vehicle body. A flexible belt is fixedly connected to the sliding frame, and the other end of the flexible belt is fixedly connected to the discharge port of the receiving device.

[0008] Preferably, the sliding frame is provided with a debris removal assembly, which includes a rotating plate rotatably connected to the sliding frame. Rotating shafts are fixedly connected to both sides of the rotating plate. A straight rod is sleeved on the right rotating shaft, and a threaded rod is slidably connected to the left rotating shaft. A slider is fixedly connected to the outer end of both the straight rod and the threaded rod. Arc-shaped guide grooves adapted to the sliders are provided on both sides of the vehicle body. The sliders are slidably connected in the corresponding arc-shaped guide grooves, and the threaded rod is provided with a straight groove section and a threaded groove section connected in sequence.

[0009] Preferably, a support member is fixedly connected to the tail of the fixed frame, and a sliding member is connected to the top of the support member by a hinge. The other end of the sliding member is fixedly connected to the bottom middle part of the sliding frame.

[0010] Preferably, two extrusion rollers are fixedly connected to the bottom of the support member, and a first guide member is fixedly connected to the tail of the fixing frame. The two extrusion rollers abut against the two sides of the first guide member and form a clamping fit. The first guide member has a stepped structure, and a third collection box is provided at the top of the base directly below the rotating plate.

[0011] Preferably, a swing assembly is provided at the bottom of the sliding frame. The swing assembly includes two screening rollers located in the middle position with connecting rods fixedly connected to their tail ends. The other end of the connecting rods is rotatably connected to a sliding rod, and the lower part of the sliding rod is slidably connected to a second guide member.

[0012] Beneficial effects: Compared with existing technologies, this device, by setting up a sorting component inside the vehicle body that can swing with the drive mechanism, enables the camellia fruit to be automatically graded by size inside the equipment after collection, effectively reducing manual sorting steps and improving the continuity and efficiency of the camellia fruit harvesting and subsequent processing. At the same time, by setting up a debris removal component on the sliding frame and utilizing the movement and flipping structure of the sliding frame, the branches, leaves and other debris mixed in with the camellia fruit can be centrally turned over and discharged, avoiding the accumulation of debris in the sorting area, thereby ensuring the smooth progress of the sorting process and improving the stability and practicality of the equipment in actual harvesting operations.

Detailed Implementation

[0022] Next, combine Figures 1-8 A specific embodiment of the present invention will be described in detail below.

[0023] refer to Figure 1 A camellia fruit collecting device for camellia oil extraction includes a base 1. Several rollers are installed at the bottom of the base 1, allowing the entire collecting device to move freely. A vehicle body 11 is fixedly connected to the top of the base 1. A receiving device 12 is fixedly connected to the front end of the top of the vehicle body 11. The receiving device 12 is mainly a collecting shed with an opening. The specific details are not described in detail here. In order to move the receiving device 12 to the target camellia tree for initial collection, symmetrically distributed clamping members 13 are slidably connected to the front end of the base 1. A first spring 14 is provided between the clamping member 13 and the base 1 for elastic clamping and limiting of the tree trunk, so that the device can stably receive the camellia fruit during the harvesting and subsequent transportation of the camellia fruit.

[0024] Furthermore, after the initial collection of camellia fruit is completed, in order to improve the efficiency and quality of subsequent oil pressing, the equipment is equipped with a sorting component inside the body 11. This sorting component is used to grade the collected camellia fruit according to size, so that camellia fruit of different specifications can be automatically separated, avoiding manual secondary sorting operations, thereby reducing labor intensity and improving the integration of collection and processing.

[0025] refer to Figure 2 and Figure 3 The receiving device 12 has a feeding component 15 fixedly connected to the bottom of its interface. The feeding component 15 is an open box with an opening in the bottom. A buffer component 29 is slidably connected to the bottom of the feeding component 15. The buffer component 29 is an inclined ramp structure that can guide the camellia fruit during its fall. A second spring 291 is provided between the buffer component 29 and the bottom of the feeding component 15, which can effectively buffer the impact force on the camellia fruit during its fall, allowing the camellia fruit to land softly and reducing the probability of damage to the camellia fruit.

[0026] refer to Figure 2 In order to drive the sorting action of the sorting component, a fixed frame 24 is fixedly connected inside the vehicle body 11. A cylinder 2 is installed on the fixed frame 24. The linkage output rod of the cylinder 2 is fixedly connected to a transmission frame 21. The transmission frame 21 is a horizontally arranged frame structure. Both ends of the transmission frame 21 are fixedly connected to sliding frames 22. The sliding frames 22 are the main load-bearing components of the sorting component.

[0027] refer to Figure 5After the collection process is completed, the camellia fruits fall to the sorting component, which includes a sieving roller 25 slidably connected to the sliding frame 22. The sieving roller 25 is a cylindrical structure and is arranged vertically at intervals on the sliding frame 22. A sieve structure is formed between any two or more adjacent sieving rollers 25, and the spacing between the sieve openings gradually changes from narrow to wide, so that the camellia fruits falling on it roll downwards under the action of gravity and complete the size grading of the camellia fruits.

[0028] refer to Figure 4 and Figure 5 Below the sieving roller 25, three first collection boxes 26 are provided. Each first collection box 26 is an open compartment with a sloping bottom, used to collect camellia fruits after being graded through different sieve openings, allowing camellia fruits of different sizes to enter the corresponding first collection box 26. A net 27 is fixedly connected to the discharge port of each first collection box 26 to catch the camellia fruits discharged from the first collection box 26 and prevent them from scattering during the fall. A second collection box 28 is installed at the rear of the vehicle body 11. The second collection box 28 is used to collect camellia fruits that have rolled off the sieving roller 25 and failed to pass through the sieve openings, allowing larger camellia fruits to be stored centrally under gravity.

[0029] Furthermore, the sliding frame 22 will swing during the sorting process. To ensure that the sliding frame 22 will not detach during this process, a flexible belt 221 is fixedly connected to the sliding frame 22. The other end of the flexible belt 221 is fixedly connected to the discharge port of the receiving device 12 to ensure the continuity of the channel.

[0030] When using a camellia fruit collection device for tea oil extraction, the rolling mechanism at the bottom of the base 1 is used to move the entire device to the target camellia tree position. The trunk is aligned with the clamping parts 13, and the trunk is clamped and limited under the action of the first spring 14 to improve the stability of the device during operation. The receiving device 12 is then activated to automatically unfold the collection shed and cover the trunk circumferentially, so that the collection shed of the receiving device 12 is located under the canopy of the camellia tree to prepare for the collection of camellia fruit.

[0031] During harvesting, the camellia trees are typically vibrated by an external vibrating device to cause the mature camellia fruits to fall from the tree. The fallen fruits fall into the collection shed of the receiving device 12. After entering the receiving device 12, they pass through the interface and enter the feeding part 15 under the action of gravity. During the falling process, the camellia fruits fall onto the buffer part 29. The second spring 291 at the bottom of the buffer part 29 can cushion the camellia fruits, thereby reducing the impact force during the falling process and preventing damage to the fruits. The camellia fruits enter the sorting assembly inside the vehicle body 11 from the feeding part 15.

[0032] When the sorting assembly is driven to swing and sway, cylinder 2 is activated. The extension and retraction of the output rod of cylinder 2 drives the transmission frame 21 to swing back and forth, and the fixed sliding frame 22 swings in sync. As the camellia fruit rolls on the surface of the sieve roller 25, it is graded according to its size difference by passing through the corresponding sieve openings and falls into the first collection box 26 located below the sieve roller 25. The larger camellia fruit that does not pass through the sieve openings continue to roll along the sieve roller 25 and eventually enter the second collection box 28 at the rear of the vehicle body 11, thus realizing the graded collection of the camellia fruit.

[0033] During the sorting process, the sliding frame 22 is connected to the discharge port of the receiving device 12 by a flexible belt 221. While maintaining the degree of freedom of the sliding frame 22 to sway, the continuity of the conveying channel of the camellia fruit in the sorting motion is ensured, and the phenomenon of detachment or leakage is avoided, thereby ensuring the stable progress of the collection and sorting process.

[0034] During the collection of camellia oleifera fruits, the fruits often fall into the equipment along with branches, leaves, and other debris that have fallen from the tree. To facilitate the centralized removal of these debris after the camellia oleifera fruits have been collected, a debris removal assembly is provided on the sliding frame 22.

[0035] The debris removal assembly includes a rotating plate 3 rotatably connected to a sliding frame 22. Rotating shafts 32 are fixedly connected to both sides of the rotating plate 3. A straight rod 34 is sleeved on the right rotating shaft 32, and a threaded rod 33 is slidably connected to the left rotating shaft 32. A slider 31 is fixedly connected to the outer end of both the threaded rod 33 and the straight rod 34. The slider 31 is an arc-shaped block structure. Arc-shaped guide grooves 36 that match the slider 31 are provided on both sides of the vehicle body 11. The slider 31 is slidably connected to the arc-shaped guide grooves 36 on both sides, so that the slider 31 can slide along the direction of the guide grooves 36 without rotating, thereby preventing the threaded rod 33 from rotating.

[0036] To enable the rotating plate 3 to flip downwards when needed, the threaded rod 33 is provided with a straight groove section and a threaded groove section connected in sequence. The straight groove section is used to provide axial sliding space for the threaded rod 33 during the movement of the rotating plate 3 with the sliding frame 22, so that the rotating plate 3 only undergoes follow-up translation without flipping during this stage. When the point of action of the rotating shaft 32 and the threaded rod 33 enters the threaded groove section, the rotating plate 3 is driven to rotate around the rotating shaft 32 through the interaction with the threaded groove section on the threaded rod 33, thereby realizing the downward flipping of the rotating plate 3.

[0037] refer to Figure 6To facilitate the tipping of the debris removal assembly and to elevate the sliding frame 22 so that debris is better concentrated at the top of the assembly, a support member 23 is fixedly connected to the tail of the fixed frame 24. A sliding member 231 is hinged to the top of the support member 23, and the other end of the sliding member 231 is fixedly connected to the bottom middle of the sliding frame 22 so that the tail of the sliding frame 22 is lifted when the support member 23 undergoes a lifting displacement.

[0038] Two squeezing rollers 242 are fixedly connected to the bottom of the support member 23, and a first guide member 241 is fixedly connected to the tail of the fixed frame 24. The two squeezing rollers 242 abut against the two sides of the first guide member 241 respectively, forming a clamping fit with the first guide member 241, so that the support member 23 can generate a stable lifting movement under the guidance of the first guide member 241 during the movement of the fixed frame 24. The first guide member 241 has a stepped structure. When the sliding frame 22 only has a swaying movement, the upper and lower squeezing rollers 243 slide back and forth on the plane of the first guide member 241 at a fixed height. When the sliding frame 22 needs to be tilted, the sliding frame 22 slides along the stepped slope of the first guide member 241, thereby ensuring that the lifting movement is smooth and orderly. In order to collect and uniformly process the debris that is overturned, a third collection box 35 is provided on the top of the base 1 directly below the rotating plate 3.

[0039] When it is necessary to overturn and discharge debris, first drive the output rod of cylinder 2 to the leftmost position, and the fixing frame 24 moves to the left synchronously with the movement of cylinder 2. During the leftward movement, the fixing frame 24 drives the support member 23 below it to move to the left as well; at the same time, under the guidance of the first guide member 241, the two squeezing rollers 242 located at the bottom of the support member 23 abut against the two sides of the first guide member 241 respectively, forming a clamping fit with the first guide member 241, so that the support member 23 gradually generates an upward lifting displacement while moving horizontally.

[0040] The lifting motion of the support member 23 is transmitted to the tail of the sliding frame 22 through its hinged sliding member 231, causing the tail end of the sliding frame 22 to be lifted upward. During this lifting process, the first guide member 241 has a stepped structure, and the two squeezing rollers 242 roll in coordination on its fixed height plane and stepped inclined surface, which can cause the branches, leaves and other debris accumulated on the sliding frame 22 to slide in the same direction under the action of gravity, and fall down and collect on the surface of the rotating plate 3, thereby realizing the centralized guidance of debris.

[0041] Simultaneously, as the sliding frame 22 moves to the left, it causes the rotating plate 3, which is rotatably connected to it, to move to the left in sync. When the rotating plate 3 moves to the left, its two rotating shafts 32, via straight rods 34 and threaded rods 33 respectively, cause the corresponding sliders 31 to slide within the arc-shaped guide grooves 36 on both sides of the vehicle body 11, thus limiting the movement trajectory of the rotating plate 3. When the point of action of the rotating shaft 32 and the threaded rod 33 is within the straight groove section, the rotating plate 3 only translates with the sliding frame 22 without flipping; as the sliding frame 22 continues to move to the left, after the point of action of the rotating shaft 32 and the threaded rod 33 enters the threaded groove section, under the threaded engagement of the threaded groove section and the rotating shaft 32, the rotating plate 3 gradually undergoes a downward flipping motion around the rotating shaft 32.

[0042] As the rotation angle of the rotating plate 3 increases, the branches, leaves and other debris accumulated on its surface slide down under the action of gravity and eventually fall into the third collection box 35 located directly below the rotating plate 3, thus completing the process of overturning and discharging the debris.

[0043] During the collection of camellia fruits, which vary in shape and have breaks on their surface, when the break is close to the surface of the sieve roller 25, it will bite into the surface of the sieve roller 25, increasing the friction. This will cause the camellia fruits that are stuck at the sieve roller 25 to stop moving forward, affecting the continuity and smoothness of the sorting process. To avoid the above problems, a swing component is provided at the bottom of the sliding frame 22, which can drive the sieve roller 25 to swing left and right during the shaking of the sliding frame 22. Even if the size of the camellia fruit is stuck at the current sieve opening, the swing of the sieve roller 25 can cause the sieve opening spacing to change, thereby detaching the camellia fruit from the sieve opening and continuing to move forward or falling to the bottom, avoiding sieve blockage and ensuring the continuous operation of the sorting process.

[0044] refer to Figure 6 and Figure 8 The oscillating assembly includes two screening rollers 25 positioned in the middle, each with a connecting rod 4 fixedly connected to its tail. The connecting rod 4 is a cross-link structure, and the other end of the connecting rod 4 is rotatably connected to a sliding rod 41, allowing the screening rollers 25 to oscillate with the movement of the sliding rod 41. The sliding rod 41 is slidably connected to a second guide member 42 below. The second guide member 42 is a curved guide groove structure used to limit and guide the movement trajectory of the sliding rod 41. The second guide member 42 extends along the bottom of the sliding frame 22. During the oscillation of the sliding frame 22, the second guide member 42 drives the sliding rod 41 to slide within the guide groove, thereby transmitting the oscillating motion to the screening rollers 25 through the connecting rod 4, causing the screening rollers 25 to oscillate laterally based on the original sorting motion.

[0045] When the camellia fruit gets stuck at the sieve opening of the sieve roller 25, the cylinder 2 drives the sliding frame 22 to shake, and the swinging component works synchronously. The second guide member 42 constrains the movement trajectory of the sliding rod 41, causing the sliding rod 41 to slide back and forth in the curved guide groove, and through the connecting rod 4, it drives the corresponding sieve roller 25 to swing left and right. During this swinging process, the relative distance at the sieve opening changes, causing the camellia fruit stuck at the sieve opening to detach from the sieve opening under its own gravity and fall through the sieve opening into the corresponding first collection box 26 below, thereby preventing the camellia fruit from accumulating at the sieve opening and ensuring that the sorting process can be carried out continuously and smoothly.

[0046] In summary, the camellia fruit collection device for camellia oil extraction provided by this invention achieves continuous processing of camellia fruit after harvesting through an integrated collection, sorting, and impurity removal structure. Compared with the problems commonly found in background technologies, such as reliance on manual sorting, difficulty in collecting and cleaning impurities, easy clogging of broken fruit openings, and insufficient overall operational continuity, this invention, by setting up a swingable sieve roller sorting component, achieves automatic grading of camellia fruit according to size, effectively avoiding sieve jamming; through the cooperation of the impurity removal component and the lifting mechanism, branches, leaves, and other impurities can be concentrated, guided, and dumped out after sorting, reducing manual cleaning steps; at the same time, the various functional structures work together within the same device, improving the integration and operational stability of the camellia fruit harvesting, sorting, and impurity removal process, thereby effectively improving the efficiency and quality of subsequent oil extraction processing, and has high practical value.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
