Specific implementation mode

[0034]

Example 1

[0035] Such as Figure 1 、 2As shown in the figure, the chili fruit picker in this embodiment includes a frame, a loading part, a separation part, a primary screening part, a secondary screening part, and a fruit conveying part, where: The frame is used to provide an assembly, transmission, and support base platform for the loading part, separation part, primary screening part, secondary screening part, and fruit conveying part of the fruit picker; The frame serves as the base structure of the above-mentioned components and is not limited by a specific structure. Any structure used to construct and realize the positional and connection relationships such as assembly, fixation, and connection of the above-mentioned parts belongs to the frame. The loading part is arranged to convey chili plant materials to the fruit picker. The separation part is used to separate the chili plant materials conveyed by the loading part from the chili stalks. The separation part includes a housing, a spiral shaft, and a main sieve mesh. The housing is arranged longitudinally along the frame. The main sieve mesh is in the shape of an arc-shaped sieve and is arranged at the lower part inside the housing. The spiral shaft is arranged in the longitudinal channel formed by the combination of the housing and the main sieve mesh; The loading part is arranged at the top of the front end of the housing, and the loading part is provided with a material guiding port for communicating with the internal longitudinal channel of the housing; The tail end of the separation part is a stalk discharging port, and the stalk discharging port is used to discharge the chili stalks (generally considered to be thicker and longer stalks, leaves, etc.) that remain in the separation part and are not leaked out of the fruit picker. Further, the primary screening part does not have specific independent structural components. In fact, it is the main sieve mesh in the separation part. The function of this main sieve mesh is that when the spiral shaft drives the spiral rod to rotate, on the one hand, the chili fruits are stirred and separated from the stalks, and on the other hand, the spiral rod pushes a part of the large stalks and leaves towards the tail in the main sieve mesh, and leaks another part of the small stalks and leaves as well as the chili fruits from the main sieve mesh, thereby realizing the preliminary screening of the chili stalks and fruits. The secondary screening part is arranged below the separation part to receive the small stalks and leaves as well as the chili fruits sifted and leaked by the main sieve mesh. The secondary screening part is used to separate the small stalks and leaves from the chili fruits sifted and leaked from the main sieve mesh. The secondary screening part is mainly a planar sieve bed formed by arranging multiple groups of row wheels. The row wheels include row shafts and convex edge wheels. The row shafts are placed horizontally, and multiple convex edge wheels are arranged at intervals on the row shafts; The convex edge wheels between adjacent row wheels are arranged in a staggered manner. The so-called secondary screening part is arranged below the separation part, which means that the secondary screening part is the next process of the separation part. The secondary screening part receives the chili stalks (generally considered to be thinner and shorter stalks, leaves, etc.) leaked from the separation part. Therefore, the positional relationship, external skin (or housing) structure, etc. of the secondary screening part are limited due to the above-mentioned needs, and it has other auxiliary components necessary to achieve its functional effects. For those skilled in the art, this can be achieved according to existing conventional technologies, so it will not be elaborated here. The fruit conveying part is used to output the selected chili fruits to an external loading device. The fruit conveying part adopts a conveying device such as a conveyor belt. The fruit conveying part is arranged below the secondary screening part to receive the chili fruits sifted and leaked by the secondary screening part.

[0036] Further, the spiral shaft is provided with a spiral rod, which is spirally arranged around the spiral shaft. The spiral direction of the spiral rod is set such that when the spiral shaft rotates and drives the spiral rod to rotate, the spiral rod can convey the materials from front to back.

[0037] Further, the spiral shaft is provided with row bars, which are arranged at the tail of the spiral shaft and corresponding to the row bar openings; there are 1 to 5 groups of row bars, and each group of row bars is composed of multiple straight bars perpendicular to the spiral shaft arranged side by side; when there are multiple groups of row bars, the groups of row bars are arranged in central symmetry with each other.

[0038] Further, each component of the fruit picker should be covered with corresponding skin, housing and other covering structures, such as the housing of the separation part, the skin around the secondary sieve part, etc. The above-mentioned skin and housing structures are used for the function realization, operation and maintenance protection, connection and shaping of each component.

[0039] During use, the complete plant of peppers is loaded into the feeding part and then enters the longitudinal channel of the separation part. The spiral shaft rotates, and the spiral rod stirs the material, causing the stem to break and the pepper stem to separate. At the same time, the spiral structure also pushes the material from the front to the rear, and further stirs the material during the pushing process to form a continuous effect of stem breaking and pepper stem separation. The main sieve mesh has oblong holes about 5 - 6 cm long and about 4 - 5 cm wide, so that the shorter stems, leaves, etc. and pepper fruits that have been broken can leak through it, while the larger stems and leaves are retained in the separation part and finally pushed to the tail row bar opening and discharged. The small rods and peppers fall on the secondary sieve part. The tops of the convex edge wheels arranged in a dense, cross - staggered and misaligned manner form a continuously rolling conveyor surface backward. The row wheels are horizontally placed and longitudinally extended, so that the top surfaces of the convex edge wheels of adjacent row wheels form a dynamic transverse shallow groove. This shallow groove can make the stem automatically lie horizontally and be pushed backward by the convex edges of the convex edge wheels and finally discharged. A conveyor belt is provided at the tail of the secondary sieve part for receiving smaller stems and discharging them outside the fruit picking phase (such as in the side direction). During the above process, there are holes between the convex edge wheels of adjacent row wheels that can allow pepper fruits to leak through. The size of the holes can be set as needed, that is, by adjusting the horizontal and / or vertical distance between the convex edge wheels, and this adjustment can be fixed or movable. Most of the peppers that leak from the secondary sieve part are fruits, which are output by the conveyor belt of the fruit conveying part and loaded onto the vehicle, and the specific implementation will not be elaborated here.

Through the trial production test of the fruit picker prototype, for the peppers planted in the place where the applicant is located, when the secondary sieve part is inclined to the above - mentioned degree, the screening effect is better.

There are two sets of the feeding hopper and / or the feeding conveyor belt, which are respectively arranged at the top positions on both sides of the front part of the separation part of the fruit picking machine. And when the feeding conveyor belt is provided, the feeding conveyor belt is hinged to the housing of the separation part to realize the adjustment of the height angle of the feeding conveyor belt. The feeding hopper and the feeding conveyor belt are symmetrically arranged on both sides of the fruit picking machine respectively. On the one hand, it is considered for the driving direction of the fruit picking machine during field operation, and the feeding on both sides can be unrestricted by the occupation of materials on the side; on the other hand, the double feeding can also improve the operation efficiency.
