Description

Technical Field

[0001] This invention relates to the field of citron harvesting equipment technology, and more particularly to a citron fruit harvesting device and method. Background Technology

[0002] Citron, as a type of Chinese medicinal herb, has good medicinal value. In order to facilitate the standardized management and harvesting of citron, the inter-row planting method is adopted, in which the citrons are planted in the same row in the field. When the citrons reach the harvest time, they are harvested, transported and stored by hand. During the harvest, storage equipment is needed to temporarily store the citrons.

[0003] In existing technologies, citron is usually collected using agricultural woven bags. When harvesting citron, farmers first collect the citron fruits into woven bags, then transport the citron fruits from the woven bags to storage vehicles or storage boxes, and then return to the harvesting point for transportation, so as to facilitate the subsequent harvesting and transportation of citron fruits.

[0004] Using the existing manual transportation method for citron fruit, farmers need to continuously carry woven bags or baskets to transport the fruit after harvesting. This method is labor-intensive and time-consuming, making it inconvenient to automatically transfer the fruit to transportation equipment after harvesting.

On the other hand, it controls the support, the discharge port, and the transfer frame to move downwards, reducing the gap between the discharge port and the collection box, facilitating stable fruit dropping. After the locking plate locks onto the collection box, the lifting mechanism can also drive the elastic telescopic member, the support, the discharge port, and the transfer frame to move downwards. The locking plate and the elastic telescopic member move relative to each other, causing the transmission rod to push the connecting shaft to move. The connecting shaft drives the slider and the brake plate to move.

[0062] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0064] This invention provides a citron fruit harvesting device.

[0065] Please refer to the following: Figures 1 to 3 In the first embodiment of the present invention, the citron fruit harvesting device includes:

[0066] box rack 1;

[0067] Collection box 2, which is movably mounted on the box frame 1;

[0068] Lifting mechanism 3, which is embedded in the box frame 1;

[0069] Locking mechanism 4, which includes an elastic telescopic member 41 and a locking plate 42, wherein the two ends of the elastic telescopic member 41 are elastically connected to the lifting mechanism 3 and the locking plate 42 respectively;

[0070] The support mechanism 5 includes a bracket 51, a material discharge port 52, and a slider 53. One end of the bracket 51 is fixed to the lifting end of the lifting mechanism 3, and the material discharge port 52 is fixed to the other end of the bracket 51. The bracket 51 has a first sliding hole 511 and a second sliding hole 512, which connects the first sliding hole 511 and the material discharge port 52. The slider 53 is slidably mounted on the bracket 51, and a brake plate 531 is fixed on the slider 53.

[0071] The transfer frame 6 is rotatably mounted on the discharge port 52. The output end of the transfer frame 6 is connected to the input end of the discharge port 52. The brake plate 531 is aligned with the transfer frame 6 through the sliding hole 512.

[0072] The connecting mechanism 7 includes a transmission rod 71 and a connecting shaft 72. The two ends of the transmission rod 71 are respectively hinged to the locking plate 42 and the connecting shaft 72. The connecting shaft 72 passes through the sliding hole 511 and is fixedly connected to the slider 53.

[0073] In this embodiment, the collection box 2 is detachably mounted on the box frame 1;

[0074] When the collection box 2 is in the locked state, the collection box 2 can be pulled out from the rear of the box frame 1 to replace the collection box 2 used for receiving and storing citron;

[0075] When the collection box 2 is in the unlocked state, the collection box 2 is stably installed on the box frame 1, which avoids instability during the receiving or transfer of the equipment and prevents the collection box 2 from sliding.

[0076] In this embodiment, one end of the transfer frame 6 is inserted into the discharge port 52 and rotatably connected. Citrons picked from the tree are placed on the transfer frame 6 for transfer. After transfer, they fall through the discharge port 52 into the lowered collection box 2 for centralized collection, reducing the movement of personnel and facilitating quick delivery to the collection box 2 after picking.

[0077] When the collection box 2 is in the unlocked state, the transfer frame 6 can be manually rotated and adjusted to facilitate its rotation, unfolding, and use. The direction and angle of use are manually controlled so that users can pick citron from the side of the collection box 2.

[0078] When the collection box 2 is needed for receiving and transporting fruit, the lifting mechanism 3 is activated, which controls the locking mechanism 4 to move downward. On one hand, this controls the locking plate 42 to move downward and lock onto the collection box 2, ensuring the collection box 2 is stably locked onto the box frame 1, increasing the stability of the collection box 2 during fruit receiving. On the other hand, it controls the support 51, the discharge port 52, and the transfer frame 6 to move downward, reducing the gap between the discharge port 52 and the collection box 2, facilitating stable fruit dropping. After locking, the lifting mechanism 3 can also drive the elastic telescopic member 41, the bracket 51, the material drop port 52 and the transfer frame 6 to move down. The locking plate 42 and the elastic telescopic member 41 move relative to each other, so that the transmission rod 71 pushes the connecting shaft 72 to move. The connecting shaft 72 drives the slider 53 and the brake plate 531 to move. The brake plate 531 passes through the second sliding hole 512 and is braked on the transfer frame 6, so as to facilitate locking after the angle adjustment of the transfer frame 6, so as to maintain the stability of picking citron and transporting it into the collection box 2.

[0079] Ultimately, under the same power drive, the automatic locking of the collection box 2 and the automatic fixing of the angle of the transfer frame 6 after it is unfolded and used are realized simultaneously; this facilitates the automatic transfer of citron fruits to the transfer equipment after harvesting.

[0080] In this embodiment, the locking plate 42 has an L-shaped structure. After the locking plate 42 moves down, it can be completely locked and abut against the collection box 2, providing support for further retraction of the elastic telescopic member 41.

[0081] The connection between the transfer frame 6 and the discharge port 52 is provided with damping rubber. This increases the frictional resistance between the transfer frame 6 and the discharge port 52, preventing the transfer frame 6 from rotating relative to the discharge port 52 without human or external force.

[0082] Please refer to the following: Figure 3 and Figure 4 The support mechanism 5 further includes a telescopic component 54, a slide 55, and a stop bar 56. The slide 55 is slidably mounted on the bracket 51. The telescopic component 54 is mounted on the bracket 51 and is used to drive the slide 55 to slide and adjust. The stop bar 56 is fixed on the slide 55 and is aligned with the discharge port 52 and the output port of the transfer frame 6.

[0083] The telescopic component 54 facilitates the telescopic adjustment of the slide 55 and the baffle 56. When it is necessary to close the output port of the transfer frame 6, the baffle 56 is extended to cover the bottom of the discharge port 52. When it is necessary to open the output port of the transfer frame 6, the baffle 56 is retracted to move away from the bottom of the discharge port 52. This ensures that when the collection box 2 is full, the discharge port 52 can be prevented from continuing to discharge. The transfer frame 6 can also temporarily store citron, allowing harvesting to continue while the citron is temporarily stored on the transfer frame 6.

[0084] In an alternative embodiment, the telescopic component 54 is a telescopic cylinder that provides power for telescopic control of the carriage 55.

[0085] In another alternative embodiment, the telescopic assembly 54 includes a first toothed plate 541, a gear 542, and a second toothed plate 543. The first toothed plate 541 is fixed on the slider 53, the gear 542 meshes with the first toothed plate 541 and the second toothed plate 543, the gear 542 is rotatably mounted on the bracket 51, and the second toothed plate 543 is fixed on the carriage 55.

[0086] While the slide 55 moves, it can drive the toothed plate 541 to move. During the movement of the toothed plate 541, the gear 542 drives the toothed plate 543 to move in the opposite direction. The toothed plate 543 synchronously drives the slide 55 and the stop bar 56 to retract adaptively, which facilitates the control of the stop bar 56.

[0087] Ultimately, under the same power drive, it is possible to adjust the lifting and lowering of the locking plate 42, control the extension and retraction of the brake plate 531, and simultaneously control the adaptive retraction of the baffle 56 to meet the needs of citron transportation and harvesting.

[0088] In an alternative embodiment, the lifting mechanism 3 may be a hydraulic telescopic bar.

[0089] In another alternative implementation, please refer to [reference needed]. Figure 2 and Figure 4 The frame 1 is provided with an adjustment hole 101;

[0090] The lifting mechanism 3 includes a telescopic component 31 and a T-shaped frame 32. The telescopic component 31 is embedded in the box frame 1, and the T-shaped frame 32 is fixed to the telescopic end of the telescopic component 31, with the bottom of the T-shaped frame 32 inserted into the range of the adjustment hole 101.

[0091] The elastic telescopic member 41 is fixed on the T-shaped frame 32, and the bracket 51 is fixed on the T-shaped frame 32.

[0092] In this embodiment, the telescopic member 31 can be an electric telescopic rod or a hydraulic telescopic bar. It provides power for the lifting and adjusting of the T-shaped frame 32; the lifting and adjusting of the support 51 and the elastic telescopic member 41 is controlled by controlling the lifting and lowering of the T-shaped frame 32.

[0093] This is to provide stable support for the bracket 51 and the elastic telescopic member 41.

[0094] In this embodiment, a slide rail 11 is fixedly mounted on the frame 1, and a slide groove 321 is provided on the T-shaped frame 32. The slide rail 11 is inserted into the slide groove 321 and slidably connected to the T-shaped frame 32. This provides support for the stable lifting and lowering adjustment of the T-shaped frame 32.

[0095] In an optional embodiment, the transfer frame 6 has a built-in independent electric conveyor belt for transferring the citron fruits placed on the transfer frame 6 to the range of the discharge port 52, thereby realizing automatic conveying and discharge.

[0096] In another alternative implementation, please refer to [reference needed]. Figure 2 and Figure 5The transfer frame 6 includes a fixed frame 61 and a sliding frame 62. The sliding frame 62 is slidably mounted on the fixed frame 61, and a guide groove 621 is provided on the sliding frame 62.

[0097] The output end of the sliding frame 62 is connected to the discharge port 52 through the fixed frame 61.

[0098] The retractable structure allows for an increase in the fruit-receiving range of the transfer frame 6, reducing the walking distance for fruit pickers and enhancing adaptability. The guide chute 621 provides support for the conveying of the fruit after receiving it, enabling the citron fruit to be adaptively conveyed to the range of the discharge port 52, facilitating the conveying and automatic discharge of the citron fruit.

[0099] In this embodiment, the fixed frame 61 is provided with a first guide groove 611, which is aligned with the lower part of the sliding frame 62, and the size of the first guide groove 611 matches the size of the second guide groove 621. This facilitates the formation of an inclined conveying structure by the first guide groove 611 and the second guide groove 621 after the sliding frame 62 is unfolded, providing support for the automatic conveying of citron fruits after harvesting.

[0100] Please refer to the following: Figure 5 and Figure 6 The fixed frame 61 is also provided with a limiting groove 612, and a sliding member 622 is fixed on the sliding frame 62 and inserted into the limiting groove 612. The sliding member 622 is slidably connected to the fixed frame 61.

[0101] The transfer frame 6 also includes a nut 63, which is threaded onto the fixed frame 61. One end of the nut 63 passes through the fixed frame 61 and abuts against the sliding member 622.

[0102] On the one hand, it increases the stability of the adjustment between the fixed frame 61 and the sliding frame 62; on the other hand, after the sliding frame 62 is adjusted to the required length, it can be locked and limited by the nut 63 to maintain the current length of the sliding frame 62.

[0103] In this embodiment, the principle of telescopic adjustment of the sliding frame 62 is as follows:

[0104] Loosen the nut 63 beforehand, and then manually control the fixed frame 61 and the sliding frame 62 to rotate to a suitable angle for picking;

[0105] like Figure 7 As shown in (a1), it can be defined that in the initial state, the sliding frame 62 is in a fully retracted state, and the guide groove 621 on the sliding frame 62 is directly connected to the discharge port 52.

[0106] Combination Figure 7 (a1) to (a2) to (a3) ​​When it is necessary to adjust the length of the sliding frame 62, manually pull the sliding frame 62 outward, so that the sliding frame 62 drives the sliding member 622 to extend outward, so that the sliding frame 62 extends relative to the fixed frame 61, increasing the overall transport length of the transfer frame 6, reducing the user's back-and-forth travel between the collection box 2 and the citron tree, and improving the harvesting efficiency;

[0107] like Figure 7 As shown in (a3), the sliding frame 62 is in a fully extended state, and the second guide groove 621 is connected to the discharge port 52 through the first guide groove 611.

[0108] In an optional embodiment, the bottom of the frame 1 is provided with an autonomous walking mechanism for autonomous walking adjustment of the equipment, so as to facilitate movement and adjustment between rows in the citron planting field.

[0109] In another alternative implementation, please refer again. Figure 2 The bottom of the frame 1 is equipped with a set of wheels; the citron fruit picking device also includes a traction hook 8, which is fixed to the frame 1. This facilitates connection to agricultural machinery via a traction rope, allowing the machinery to provide power for the movement and adjustment of the frame 1.

[0110] The working principle of the citron fruit harvesting device provided by this invention is as follows:

[0111] like Figure 8 (b1) and Figure 9 As shown in (c1), it can be defined that in the initial state, the locking plate 42 is in the unlocked state, the elastic telescopic member 41 is in the extended state, the brake plate 531 is in the unlocked state, and the stop bar 56 is in the extended state.

[0112] Combination Figure 8 In (b1) to (b2), when it is only necessary to lock the collection box 2, the elastic telescopic member 41 is controlled to move down by the lifting mechanism 3, the elastic telescopic member 41 drives the locking plate 42 to move down, and the locking plate 42 moves down to completely lock the collection box 2;

[0113] Combination Figure 8 In (b2) to (b3), when it is necessary to control the retraction of the baffle 56 and the opening of the material drop port 52, the lifting mechanism 3 continues to control the elastic telescopic member 41 to move down, so that the elastic telescopic member 41 moves down relative to the locking plate 42;

[0114] At the same time, the lifting mechanism 3 also controls the bracket 51 and the transfer frame 6 to move downward as a whole, in conjunction with the reference. Figure 9 In the (c1) to (c2) to (c3) sections, when the bracket 51 moves down, the transmission rod 71 pushes the slider 53 forward through the connecting shaft 72, and the slider 53 drives the brake plate 531 to move forward synchronously. After the brake plate 531 has moved forward completely, it can abut against the transfer frame 6 through the sliding hole 2 512 to lock the use angle of the transfer frame 6.

[0115] As the slider 53 moves forward, it drives the toothed plate 541 to move forward. The toothed plate 541 drives the toothed plate 543 to move backward through the gear 542. The toothed plate 543 drives the baffle 56 to move backward in sync, so that the baffle 56 gradually moves away from the discharge range of the discharge port 52, so that the transfer frame 6 can transport citron fruits normally and discharge normally.

[0116] like Figure 8 In Figure (b3) and Figure (9) (c3), the locking plate 42 is in a locked state, the elastic telescopic member 41 is in a compressed state, the brake plate 531 is in a locked state (used to lock the transfer frame 6), and the stop bar 56 is in a retracted state.

[0117] Ultimately, under the same power drive, the collection box 2 can be automatically locked, the discharge port 52 can be automatically opened, and the transfer frame 6 can be fixed to the required angle after adjustment, thus maintaining the stability of citron fruit transportation after harvesting.

[0118] Similarly, when it is necessary to unlock the full collection box 2, the lifting mechanism 3 controls the elastic telescopic member 41 and the locking plate 42 to move upward to unlock. During the upward movement, the transfer frame 6 is unlocked and can be angled, and the discharge port 52 is automatically closed. During the replacement of the collection box 2, the transfer frame 6 can serve as a temporary storage device to facilitate the temporary storage of harvested citron fruits.

[0119] This invention also provides a method for harvesting citron fruits, comprising the following steps:

[0120] Step S1: Move the citron fruit harvesting device to the citron field rows and move it along the field.

[0121] Step S2: During the movement of the citron fruit picking device, the picking user unfolds the transfer frame 6 to a suitable angle for picking and placing the fruit.

[0122] Step S3: After picking the citron fruit, the user places it directly within the conveying range of the transfer rack 6, so that the citron fruit is adaptively transferred along the transfer rack 6 to the discharge port 52, and the citron fruit is automatically collected in the collection box 2 through the discharge port 52, reducing the time required for the user to transport the citron fruit back and forth and improving the efficiency of citron fruit picking.

[0123] In step S4, when the collection box 2 is full and needs to be replaced, the transfer frame 6 temporarily stores and supports the citron fruits that are to be harvested, reducing the waiting time required to replace the collection box 2 and further improving efficiency.

[0124] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
