[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is combined Figures 1-3 This invention describes a vegetable and fruit harvesting device.

[0023] like Figure 1 As shown, in the prior art, a harvester includes: a vehicle body 10, a harvesting platform 20, an elevator 30, a cleaning conveyor 40, and a collection bin 50. During the movement of the vehicle body 10, the harvesting platform 20 cuts the chili peppers along with their branches. The elevator 30 then conveys the chili peppers with branches to the cleaning conveyor 40 for cleaning. The cleaning conveyor 40 separates the chili peppers from the branches and then conveys them to the collection bin 50. However, the cleaning conveyor 40 sometimes fails to separate the chili peppers from the branches, resulting in some chili peppers remaining attached to the branches in the collection bin 50, along with some residual branches and leaves. Based on this, this embodiment of the invention provides a new vegetable and fruit harvesting device.

[0024] like Figure 2As shown in the embodiment of this utility model, the vegetable and fruit harvesting device includes: a body 1, a first elevator 2, a sorting and conveying mechanism 3, and a cleaning and conveying mechanism 4. The body 1 is equipped with a harvesting mechanism 11, and the sorting and conveying mechanism 3 and the cleaning and conveying mechanism 4 are disposed on the body 1. The first elevator 2 is used to convey the vegetable and fruit with branches harvested by the harvesting mechanism 11 to the sorting and conveying mechanism 3. The sorting and conveying mechanism 3 is used to remove the vegetable and fruit from the branches and convey the separated vegetable and fruit to the cleaning and conveying mechanism 4. The cleaning and conveying mechanism 4 is used to separate the vegetable and fruit from the branches and leaves.

[0025] Specifically, both the sorting and conveying mechanism 3 and the cleaning and conveying mechanism 4 are mounted on the chassis 12 of the machine body 1. During the machine body 1's movement, the harvesting mechanism 11 cuts the vegetables and fruits along with the branches. The vegetables, fruits, and branches are then conveyed together by the first elevator 2 to the sorting and conveying mechanism 3. As they are conveyed in the sorting and conveying mechanism 3, they are cut, allowing the vegetables and fruits to be removed from the branches. The separated vegetables and fruits then enter the cleaning and conveying mechanism 4, along with some branches and leaves. The cleaning and conveying mechanism 4 is equipped with a fan, which uses airflow to separate the lighter branches and leaves from the heavier vegetables and fruits. The cleaning and conveying mechanism has a first discharge port and a second discharge port. The heavier vegetables and fruits are discharged through the first discharge port, while the lighter branches and leaves are discharged through the second discharge port.

[0026] Furthermore, in this embodiment, the specific structure of the harvesting mechanism 11 is the same as that of the harvesting platform 20 in the prior art, so it will not be described again here.

[0027] The first elevator 2 includes a cylinder connected to the machine body 1. A disc is provided at the first end of the cylinder, and a conveyor belt is provided inside the cylinder, extending into the disc. The second end of the cylinder faces the sorting and conveying mechanism 3. Vegetables and fruits with branches harvested by the harvesting mechanism 11 fall into the disc and are conveyed to the sorting and conveying mechanism 3 by the conveyor belt.

[0028] Optionally, in an embodiment of this invention, the vegetable fruit can be a chili pepper. For ease of description, the embodiments of this invention will be described using a chili pepper as the vegetable fruit.

[0029] The vegetable and fruit harvesting device provided in this embodiment of the utility model, by setting up a sorting and conveying mechanism and a cleaning and conveying mechanism, picks the vegetables and fruits from the branches in the sorting and conveying mechanism, and separates the vegetables and fruits from the branches and leaves in the cleaning and conveying mechanism, thereby reducing the impurities in the harvested vegetables and fruits and improving the cleanliness of the vegetables and fruits.

[0030] In an embodiment of this utility model, the sorting and conveying mechanism 3 includes: a first housing, a first conveyor belt, and a cutter. The first housing is connected to the cleaning and conveying mechanism 4. The first conveyor belt is disposed inside the first housing and is used to convey peppers with branches attached. The cutter is disposed above the first conveyor belt, and there is a gap between the cutter and the first conveyor belt, which is larger than the diameter of the branch so that the branch can extend into the gap. When the first conveyor belt conveys peppers with branches attached, when the peppers and branches are conveyed to the cutter, the branches are conveyed into the gap between the cutter and the first conveyor belt under the action of the first conveyor belt, while the peppers continue to move forward under the action of inertia. The cutter removes the peppers from the branches. The separated peppers pass over the cutter by inertia and enter the cleaning and conveying mechanism 4, while the branches fall into the first housing through the gap.

[0031] Furthermore, the two ends of the blade are connected to the first housing, and one side of the blade is comb-shaped to pick the chili peppers from the branches.

[0032] In this embodiment, when there are many branches and leaves gathered in front of the cutter, some branches and leaves will also enter the cleaning and conveying mechanism 4 under the action of inertia.

[0033] In an embodiment of this utility model, the cleaning and conveying mechanism 4 includes a second housing and a second conveyor belt. The second conveyor belt is disposed within the second housing, and a fan is installed inside the second housing. The fan's outlet direction is the same as the conveying direction of the second conveyor belt. After the chili peppers and branches enter the cleaning and conveying mechanism 4 through the sorting and conveying mechanism 3, they fall directly onto the second conveyor belt. During the conveying process, the fan blows up the lighter branches and leaves, which are discharged from the second outlet, while the chili peppers are discharged from the first outlet under the action of the second conveyor belt.

[0034] like Figure 2 As shown in the embodiment of this utility model, the vegetable and fruit harvesting device further includes a discharge conveying mechanism 5. The first end of the discharge conveying mechanism 5 is connected to the second discharge port, and the second end of the discharge conveying mechanism 5 is disposed facing outward from the machine body 1. In this embodiment, the discharge conveying mechanism 5 is vertically inclined to utilize the gravity of the branches and leaves to discharge them. By tilting the discharge conveying mechanism 5, the branches and leaves can be discharged outside the machine body 1, preventing them from accumulating on the machine body 1 and affecting its heat dissipation effect.

[0035] like Figure 2As shown, when chili peppers and leaves are separated in the cleaning and conveying mechanism 4, incomplete separation occurs because some leaves are pressed down by the chili peppers. Therefore, in this embodiment of the invention, the vegetable and fruit harvesting device further includes a second elevator and a centrifugal sorting mechanism 6. Both the second elevator and the centrifugal sorting mechanism 6 are mounted on the machine body 1. The second elevator can be connected to the first discharge port, or the second elevator can be opposite to the first discharge port, to transport the chili peppers and residual leaves output from the first discharge port to the centrifugal sorting mechanism 6 for secondary separation.

[0036] Furthermore, in an embodiment of this utility model, the centrifugal sorting mechanism 6 is a centrifugal separator. The centrifugal separator is provided with a third discharge port and a discharge port 61. After the chili peppers and residual branches and leaves enter the centrifugal separator, the centrifugal separator uses centrifugal force to separate the heavier chili peppers and the lighter branches and leaves. The chili peppers are discharged from the third discharge port, and the branches and leaves are discharged from the discharge port 61.

[0037] In this embodiment, the specific structure of the second elevator can be referred to the structure of the first elevator 2, so it will not be described again.

[0038] In the embodiments of this utility model, by setting up a sorting and conveying mechanism 3, a cleaning and conveying mechanism 4, and a centrifugal sorting mechanism 6, peppers can be picked from the branches, and the peppers and branches and leaves can be separated twice, so that there are no branches and leaves left in the harvested peppers, eliminating the need for manual sorting and improving the sorting capacity and automation level of the vegetable and fruit harvesting device. At the same time, by setting up the sorting and conveying mechanism 3 and the cleaning and conveying mechanism 4 between the centrifugal sorting mechanism 6 and the first elevator 2, the problem of branches and leaves accumulating on the machine body 1 and affecting the heat dissipation effect of the machine body 1 in existing harvesters can be solved.

[0039] like Figure 3 As shown, in this embodiment of the invention, the vegetable and fruit harvesting device further includes a third elevator 7. The third elevator 7 is mounted on the machine body 1, with its outlet facing outwards from the machine body 1, so that the third elevator 7 can transport the peppers after passing through the centrifugal sorting mechanism 6 to the storage device. In this embodiment, the first end of the third elevator 7 can be positioned opposite to the third discharge port of the centrifugal sorting mechanism 6. The peppers output from the third discharge port can fall directly onto the first end of the third elevator 7, and then be transported to the storage device by the third elevator 7. The storage device is a transport vehicle that moves synchronously with the machine body.

[0040] In this embodiment, the specific structure of the third elevator 7 can be set with reference to the first elevator 2, so it will not be described again.

[0041] like Figure 3As shown, in this embodiment of the invention, the storage device is a transport vehicle 9. The vegetable and fruit harvesting device also includes a driver 8, which is mounted on the machine body 1. In this embodiment, the third elevator 7 is hinged to the machine body 1. The driver 8 can be a hydraulic cylinder, with its cylinder body mounted on the machine body 1, and its telescopic rod connected to the third elevator 7. The first end of the third elevator 7 is opposite to the third discharge port of the centrifugal sorting mechanism 6. When the telescopic rod extends or retracts, it can drive the third elevator 7 to rotate, thereby adjusting the height of the second end of the third elevator 7 to match the height of the transport vehicle 9, preventing the peppers from being damaged due to excessive height of the second end of the third elevator 7. In this embodiment, the transport vehicle 9 moves synchronously with the machine body 1 to achieve simultaneous harvesting and storage.

[0042] In this embodiment, by setting up a transport vehicle 9, the harvesting and storage transportation are separated, which reduces the number of times the collection box needs to be unloaded during the harvesting process, increases the storage and transportation capacity during sequential harvesting operations, and improves the overall operating efficiency of the vegetable and fruit harvesting device.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
