Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a vegetable crop harvester and a harvesting method thereof. Background Art

[0002] In agriculture, cabbage cultivation varies significantly by variety and location. Different varieties of cabbage have specific requirements for spacing and ridge height, and the size of the cabbage varies depending on the location. This diversity brings many challenges to the harvest of cabbage. First, small cabbage is more difficult to harvest than Chinese cabbage because its smaller size makes it difficult to accurately remove the rhizome. Second, the leaves of Chinese cabbage are scattered, and it is easy to accidentally damage the leaves when cutting the roots during harvesting. In addition, during the harvesting process, the position of the cabbage is difficult to center because it needs to be constantly adjusted according to the route of the ridge and the planting route of the cabbage. Moreover, the required ridge height and spacing vary in different operating environments, which requires constant adjustments, making it difficult to ensure the quality of the harvest.

[0003] Although the existing cabbage harvesters have made some progress in the market, they still have deficiencies in terms of harvesting quality and adaptability to different terrains. Traditional cabbage harvesters are complex and bulky, and need to be towed by a tractor, which makes them less adaptable and easy to use. For large-scale cabbage planting terrain, although they can achieve rapid harvesting, there is still room for improvement in accuracy and efficiency; and for small-scale greenhouse terrain, their adaptability is limited because they cannot adapt well to cabbage of different regions and varieties.

[0004] The existing cabbage harvester adopts a direct clamping method, which will damage the cabbage during the clamping process, and the root may not be accurately cut off. In addition, the existing cabbage harvester uses a power source to drive the differential to make the machine turn and adjust, which has poor flexibility and sensitivity. Since it is necessary to make continuous adjustments according to the ridge route and the cabbage planting route during the harvesting process, this steering method is difficult to meet actual needs. Moreover, the existing products use a clamping method to achieve harvesting, which will also cause damage to the leaves. . Summary of the invention

[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] See also Figure 1 to Figure 2As shown, a vegetable crop harvester in a first embodiment of the present invention is shown, comprising: a frame 10, a driving mechanism 20 arranged on the frame 10, a separation and conveying mechanism 30, a root cutting mechanism 40 and a folding mechanism;

[0046] The separation and conveying mechanism 30 is obliquely arranged on the frame 10, and the end of the separation and conveying mechanism 30 and the top of the rear end of the frame 10 form a receiving cavity 60 for receiving the cut vegetable crops;

[0047] The root cutting mechanism 40 and the gathering mechanism are arranged at the beginning of the separation and conveying mechanism 30. The gathering mechanism includes two stem supporters 50 which are arranged at intervals and are used to gather the leaves of the vegetable crops and guide their stems to the cutting area of ​​the root cutting mechanism 40.

[0048] The output shaft of the driving mechanism 20 drives the root cutting mechanism 40 and the separation and conveying mechanism 30 respectively. The root cutting mechanism 40 is used to cut the stems of the vegetable crops guided to the cutting area, and the separation and conveying mechanism 30 is used to separate the cut vegetable crops and convey them to the accommodating cavity 60.

[0049] It is worth noting that the harvester is aligned with the ridge, and the driving mechanism 20 is started to drive the separation and conveying mechanism 30 and the root cutting mechanism 40; the harvester is pushed to move along the ridge direction, so that the two stem supports 50 gather the leaves of the vegetable crops and guide their stems to the cutting area of ​​the root cutting mechanism 40 to ensure accurate cutting; the vegetable crops guided to the cutting area are cut by the root cutting mechanism 40, and the cut vegetable crops are separated by the separation and conveying mechanism 30 and conveyed to the accommodating cavity 60; the movement direction of the harvester is adjusted by pushing the handrail 13 on one side of the frame 10. The leaves of the vegetable crops are gathered by the two stem supports 50 and their stems are guided to the cutting area of ​​the root cutting mechanism 40, thereby ensuring the harvest quality, using the hand-held walking method and using the speed difference of the two wheels to achieve steering, improving flexibility and sensitivity, and separating and conveying the vegetable crops by the separation and conveying mechanism 30, avoiding the clamping method and reducing damage to the leaves.

[0050] See also Figure 3 As shown, specifically, the stem support device 50 includes a parallel section 51, a connecting section 52 and an arranging section 53 connected in sequence, the parallel sections 51 of the two stem support devices 50 are parallel and spaced apart, the connecting section 52 is connected to the parallel section 51 at an angle of 30°-60°, the arranging sections 53 of the two stem support devices 50 are inclined in directions away from each other to form an angle of 10°-30°, and one end of the arranging section 53 away from the connecting section 52 is tilted upward by 5°-15°.

[0051] More specifically, a transport groove 31 is provided on the partitioning and conveying mechanism 30 , the parallel section 51 is embedded in the transport groove 31 , and the parallel section 51 is coplanar with the bottom plate 32 of the partitioning and conveying mechanism 30 ; the sorting section 53 is connected to the partitioning and conveying mechanism 30 via a fixing section 54 .

[0052] In specific implementation, during the actual operation of the harvester, when the machine moves forward, the stem support 50 continues to move close to the vegetable crop (cabbage). At this time, the two sorting sections 53 that form an angle gradually guide the cabbage on the ridge that is not directly in front of the parallel section 51 to the connecting section 52; at the connecting section 52, the cabbage is cut at the root by the root cutting mechanism 40. The cut cabbage is then introduced between the two adjacent parallel sections 51. Since the parallel section 51 is coplanar with the bottom plate 32 of the partitioning and conveying mechanism 30, the cabbage is smoothly guided to the bottom surface (bottom plate 32) of the partitioning and conveying mechanism 30, and is finally transported by the partitioning and conveying mechanism 30. The hand-held design allows farmers to directly operate it, realizes human-machine collaborative operation, improves flexibility, does not require tractor traction, and improves adaptability and usability.

[0053] See also Figure 4 As shown, specifically, the frame 10 includes a mounting frame 11, a rear wheel 12 disposed on the mounting frame 11, and two handrails 13 disposed at the rear end of the mounting frame 11, and the gripping portion of the handrails 13 is coated with an anti-slip rubber layer. The mounting frame 11 can be made of stainless steel.

[0054] See also Figure 4 As shown, the driving mechanism 20 includes a fixing frame 21 installed at the bottom of the frame 10 and a driving source 22 arranged on the fixing frame 21, and the driving source 22 is a gasoline engine or an electric motor. Its output shaft is connected to a transmission bevel gear. The transmission bevel gear is meshed with the first bevel gear 351 of the transmission structure 35, and the first bevel gear 351 is meshed with the sixth bevel gear 41 of the root cutting mechanism 40, so that the driving source 22 drives the first bevel gear 351 and the sixth bevel gear 41 to rotate.

[0055] See also Figure 5 As shown, specifically, the root cutting mechanism 40 is engaged with the sixth bevel gear 41 of the output shaft of the driving mechanism 20, the first transmission universal joint 42 connected to the sixth bevel gear 41, the second transmission universal joint 43 connected to the first transmission universal joint 42, the third transmission universal joint 44 connected to the second transmission universal joint 43 and the rotating cutter disc 45 connected to the third transmission universal joint 44, and a support frame 46 is installed at the bottom of the separating and conveying mechanism 30, and the support frame 46 fixes the rotating cutter disc 45 through a bearing.

[0056] See also Figures 6 to 8As shown, specifically, the separation conveying mechanism 30 includes a bottom plate 32 obliquely mounted on the frame 10 through a mounting platform 33, two conveying structures 34 and a transmission structure 35 spaced apart on the top of the bottom plate 32;

[0057] The driving mechanism 20 drives the two conveying structures 34 to work through the transmission structure 35. The conveying structure 34 includes a first pulley 341 arranged at both ends of the mounting plate and a conveyor belt 342 wrapped around the two first pulleys 341. A plurality of transmission plates 343 are arranged on the conveyor belt 342 of one of the conveying structures 34, and the size of the transmission plate 343 corresponds to the interval between the two conveying structures 34.

[0058] In this embodiment, a fixing bar 36 is further provided on the top of the conveying structure 34 for cooperating with the bottom plate 32 to install the conveying structure 34 .

[0059] In the specific implementation process, the cut cabbage is smoothly guided to the bottom plate 32 of the separation conveying mechanism 30. The separation conveying mechanism 30 adopts a double conveyor belt 342 structure to form a vertical conveyor belt 342, and there are equidistantly arranged transmission plates 343 (the width is precisely matched with the interval of the conveyor belt 342) between the two conveyor belts 342, and independent separation transmission cavities are formed between adjacent transmission plates 343. Through the continuous push of the transmission plates 343, the cabbage moves along the bottom plate 32 toward the accommodating cavity 60, and finally falls into the storage frame in the accommodating cavity 60.

[0060] It can be understood that, through the corresponding design of the transmission plate 343 and the conveyor belt 342, each separated transmission cavity only accommodates a single cabbage, avoiding collision or stacking of cabbages during transportation, and reducing the damage rate of cabbage leaves. The vertical conveyor belt 342 vertically clamps the cabbage in the cavity through the structure of the counter-rotating double conveyor belts 342 (rotation speed 0.5-1.2m / s) and the transmission plate 343, reducing direct friction with the surface of the equipment, and further ensuring the integrity of the cabbage.

[0061] More specifically, the transmission structure 35 includes a first bevel gear 351 meshed with the output shaft of the driving mechanism 20, a second pulley 352 coaxially connected to the first bevel gear 351, a third pulley 354 connected to the second pulley 352 through a synchronous belt 353, a transmission rod 355 connected to the third pulley 354, and a second bevel gear 356 and a third bevel gear 357 mounted on the transmission rod 355;

[0062] The second bevel gear 356 and the third bevel gear 357 are respectively meshed with the fourth bevel gear 358 and the fifth bevel gear 359, and the fourth bevel gear 358 and the fifth bevel gear 359 respectively drive the first pulleys 341 of the two conveying structures 34, and the spiral directions of the second bevel gear 356 and the third bevel gear 357 are opposite to each other, so that the two conveyor belts 342 rotate in opposite directions.

[0063] See also Fig. 9 As shown, specifically, the front end of the separation conveying mechanism 30 is connected to the two front wheels 14 through an adjustment mechanism 70, and the adjustment mechanism 70 includes:

[0064] A fixing rod 71 is vertically welded to the side wall of the separation and conveying mechanism 30 and is provided with a plurality of fixing grooves 72 arranged at equal distances;

[0065] A support leg 73, one end of which is connected to the separation conveying mechanism 30 through a hinge, and the other end of which is connected to the front wheel 14;

[0066] A fixing bolt 74 passes through a through hole 75 in the middle of the support leg 73 and cooperates with the fixing slot 72 to adjust the height of the front wheel 14;

[0067] The axes of the two front wheels 14 are staggered to adapt to uneven terrain.

[0068] It is worth noting that the height-adjustable adjustment mechanism 70 is designed to realize the harvesting operation of cabbages of different terrains, different varieties, and different ridge heights.

[0069] This application has the following advantages:

[0070] 1. Precision cutting and adaptive harvesting:

[0071] Through the two-stage design of the stem support (the parallel section guides the stem, and the sorting section gathers the leaves), combined with the rotating cutter disc driven by the bevel gear-universal joint transmission (speed 800-1500r / min), precise cutting of the cabbage roots can be achieved, and the leaf damage rate is reduced to less than 5%. At the same time, it can adapt to cabbages with different plant spacings, and the harvest quality is significantly improved.

[0072] 2. Modular transmission and efficient harvesting:

[0073] The bevel gear transmission system with a single power source simplifies the mechanical structure and improves maintenance efficiency by 40%. The separation and conveying mechanism uses a counter-rotating vertical conveyor belt and L-shaped transmission plate to separate and convey cabbage leaves individually, avoiding the squeezing and damage of cabbage leaves caused by traditional clamping. With adjustable support legs (height adjustment range 20-60cm), it can quickly adapt to different ridge heights and cabbage varieties, and the terrain adaptability is improved by 60%.

[0074] 3. Flexible control and portable operation:

[0075] The walk-behind design combined with a differential steering wheel set allows ±30° steering adjustment by pushing the single-sided hand lever, increasing steering sensitivity by 50%, eliminating dependence on tractors; the weight of the entire machine is reduced to less than 80kg, making it suitable for small-scale planting scenarios such as greenhouses and hills, with an operating efficiency of 0.5 acres / hour, significantly enhancing its practicality.
