[0030] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.
[0031] Figure 1 The structure diagram of a fruit picking cylinder of the utility model is shown, and the structure and principle of the picking cylinder are as follows:
[0032] like Figure 1 As shown, a fruit picking barrel is characterized in that it includes a picking barrel body 1, and the picking barrel body 1 is a hollow cylindrical structure; a first incision 106, the first incision 106 is opened on the picking barrel body 1, and the contour line shape of the first incision 106 is "V" shaped; a shearing mechanism 102, the shearing mechanism is installed on the picking barrel body, and the shearing range of the shearing mechanism 102 covers the narrow end of the first incision 106; a transmission pipe 104, and the transmission pipe 104 is connected to the end of the picking barrel body 1 away from the first incision 106.
[0033] Preferably, the picking barrel includes two guide rails 101, and the guide rails 101 are installed on the inner surface of the picking barrel body 1. The guide rails 101 are installed parallel to the contour line of the first incision 106, and the guide rails 101 are installed close to the first incision 106. The surface of the guide rails 101 is smooth and can slide on the surface of the fruit to be picked when the picking barrel body 1 rotates, so as to constrain and correct the position of the fruit stalks to be picked. When the distance between the guide rails 101 and the incisions is continuously reduced to the same as the outer diameter of the fruit stalks, the fruit stalks are positioned to facilitate the next step of the shearing mechanism 102 to shear the fruit stalks.
[0034] Preferably, in this embodiment, the height of the first plane 1011 of the guide rail 101 is smaller than the height of the second plane 1012 of the guide rail 101, and the guide rail 101 smoothly transitions between the first plane 1011 and the second plane 1012. The second plane 1012 of a certain height can ensure that, when the shearing mechanism 102 shears the fruit stem, there is a certain vertical distance between the fruit stem and the blade 1021 in the shearing mechanism 102, so that the fruit stem has a certain height after shearing, thereby increasing the storage time or satisfying the aesthetic needs.
[0035] Preferably, in this embodiment, the shearing mechanism 102 includes a blade 1021 and a protective net 1022, the protective net 1022 covers the operating radius of the blade 1021, and a notch is provided at the position where the protective net 1022 cooperates with the first incision 106. The protective net 1022 can prevent the blade 1021 from accidentally scratching the fruit trees or fruit farmers. The notch allows the stalks of the fruits to be picked to enter the operating range of the blade 1021, so that the shearing operation can proceed smoothly.
[0036] Preferably, in this embodiment, the blade 1021 includes a first blade surface 10211, a second blade surface 10212 and a blunt surface 10213, the angle between the first blade surface 10211 and the second blade surface 10212 is β, and the angle β≤30°. The first blade surface 10211 and the second blade surface 10212 are installed on the blunt surface 10213, and the angle β≤30° achieves a balance between the sharpness and the service life of the blade 1021. The blunt surface 10213 can push the cut fruit stalk after the blade completes cutting the fruit stalk, so that the fruit stalk and the fruit connected to the fruit stalk can better break away from the first incision 106, avoiding the fruit stalk from being stuck at the narrow end of the first incision 106.
[0037] In the preferred embodiment, the narrow end of the first incision 106 is connected to the second incision 107, the contour line shape of the second incision 107 is circular, the inner diameter of the second incision 107 is slightly larger than the width of the narrow end of the first incision 106, and under the push of the blunt surface 10213, the sheared fruit stalk enters the second incision 107, and the inner diameter of the second incision is slightly larger than the narrow end of the first incision 106, so that the fruit stalk can be more easily separated from the picking tube body 1 and enter the transmission pipe 104.
[0038] Preferably, in this embodiment, the picking barrel includes a pressure sensor 103, and the pressure sensor 103 is installed at the connection between the picking barrel body 1 and the transmission pipe 104. The pressure sensor 103 can measure the weight of the picked fruits, so as to facilitate the grading and packaging of the picked fruits according to weight standards during the transmission process.
[0039] The utility model also provides an automatic fruit picking and packaging device, wherein the automatic fruit picking and packaging device comprises the picking barrel provided by the utility model.
[0040] Preferably, in this embodiment, the automatic fruit picking and packaging device includes a packaging mechanism 2 , and the packaging mechanism 2 is connected to the transmission pipeline 104 .
[0041] Preferably, in this embodiment, the packaging mechanism 2 includes a packaging barrel 201 and a turntable 202. There are several packaging barrels 201, and the packaging barrels 201 are evenly installed on the turntable 202 in the circumferential direction. The packaging mechanism can control the second motor 203 to drive the turntable 202 to drive different packaging barrels 201 located on the turntable 202 through the fruit weight signal of the pressure sensor arranged at the connection between the picking barrel body 1 and the transmission pipeline 104, so as to realize automatic grading and packaging of fruits of different weights from the transmission pipeline 104.
[0042] Figure 2 The utility model shows a schematic diagram of the structure of an automatic fruit picking and packaging device;
[0043] Figure 3 Shows Figure 1 Schematic diagram of the structure of the middle guide rail;
[0044] Figure 4 Shows Figure 1 Structural diagram of the middle shear mechanism;
[0045] Figure 5 Shows Figure 4 Schematic diagram of the structure of the middle blade.
[0046] When the utility model is in use, the wide end of the first incision 106 on the picking tube body 1 is firstly aligned with the fruit to be picked by using the joystick 3. The joystick 3 can be flexibly rotated and extended to adapt to fruits in different positions. The first motor 105 drives the picking tube body 1 to rotate a certain angle so that the first incision 106 is slidably sleeved on the outer periphery of the fruit stem to be picked. At the same time, the guide rail 101 slides on the surface of the fruit to be picked. During the rotation of the picking tube body 1, the first incision 106 realizes lateral constraint and correction of the fruit stem. The guide rail 101 constrains and corrects the distance between the fruit and the first incision 106, that is, the reserved length for cutting the fruit stem. A corrugated structure is arranged at the position where the conveying pipeline 104 is connected to the picking tube body 1 and the packaging mechanism 2. The corrugated structure is elastic and can be stretched or compressed to a certain length, which is convenient for the first motor 105 to drive The picking barrel body 1 rotates, and after the fruit stalk is stuck in the narrow end of the first incision 106, the blade 1021 of the shearing structure 102 rotates driven by the driving mechanism, and the first blade surface 10211 and the second blade surface 10212 thereon shear the fruit stalk, and the blunt surface 10213 pushes the sheared fruit stalk out of the first incision 106. After the sheared fruit stalk is pushed into the second incision 107, it is easier to separate from the picking barrel body 1 under the action of the gravity of the fruit. When the fruit enters the conveying pipeline 104 through the picking barrel body 1, the pressure sensor 103 collects the weight information of the fruit. After receiving the fruit weight signal, the packaging mechanism 2 located on the automatic fruit picking and packaging device controls the second motor 203 to drive the turntable 202 to drive different packaging barrels 201 located on the turntable 202, so as to realize automatic grading and packaging of fruits of different weights from the transmission pipeline 104.
[0047] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
