[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0027] Referring to Figures 1-4 ,
[0028] The application discloses a variable-diameter device for a harvesting device, which comprises a pressing part 1, a transmission part 2, a variable-diameter assembly 3, a cutting platform 4 and a driving part 5. The driving part 5 drives the pressing part 1 to rotate around a first fixed axis through the transmission part 2. The transmission part 2 and the pressing part 1 are provided in plurality. The variable-diameter assembly 3 is used for lengthening and shortening the distance between the pressing part 1 and the first fixed axis; the cutting platform 4 is provided with a storage cavity for accommodating crops, and the storage cavity is used for accommodating crops pressed or pushed by the pressing part 1. The pressing part 1 is a plurality of rod bodies and is used for pushing crops; during the process that the cutting platform 4 cuts off crops, the pressing part 1 pushes the crops so that the crops are pushed towards the cutting platform 4, thereby the crops are better cut off and directly fall into the storage cavity of the cutting platform 4. The driving part 5 is a driving motor which drives the transmission part 2 and the pressing part 1 to rotate; the variable-diameter assembly 3 connects the pressing part 1 and the transmission part 2, and the variable-diameter assembly 3 makes the pressing part 1 away from or close to the transmission part 2, thereby lengthening and shortening the distance between the pressing part 1 and the first fixed axis. By adjusting the distance between the pressing part 1 and the first fixed axis, the pressing part 1 can push crops at different positions, thereby different crops can be better pushed in different degrees. For example, when the crops are hard wheat stalks, the distance between the pressing part 1 and the first fixed axis is short, and then the crops are pushed; when the crops are soft wheat stalks, the distance between the pressing part 1 and the first fixed axis is long, and then the crops are pushed. The distance between the pressing part 1 and the first fixed axis is mainly adjusted so as to push different crops in different ways; when the distance between the pressing part 1 and the first fixed axis is short, the resistance of the pressing part 1 rotating is small due to the lever principle, and the energy consumption is low, thereby the energy-saving effect is considered.
[0029] Specifically, the variable-diameter assembly 3 comprises an electric push rod; the transmission part 2 comprises a first transmission structure 21 and a second transmission structure 22; one end of the electric push rod is connected with the first transmission structure 21, and the other end is connected with the second transmission structure 22. The first transmission structure 21 and the second transmission structure 22 are both rod bodies, and the electric push rod is arranged between the first transmission structure 21 and the second transmission structure 22. The first transmission structure 21 is connected with the driving part 5, and the second transmission structure 22 is connected with the pressing part 1, thereby realizing that the pressing part 1 is close to or away from the first fixed axis, and the driving part 5 drives the first transmission structure 21, the second transmission structure 22, the variable-diameter assembly 3 and the pressing part 1 to rotate around the first fixed axis.
[0030] Specifically, an external telescopic pipe is arranged on the electric push rod, and the telescopic pipe wraps the electric push rod; one end of the telescopic pipe is connected with the first transmission structure 21, and the other end is connected with the second transmission structure 22. The telescopic pipe is used for wrapping the electric push rod and plays a protection role on the electric push rod.
[0031] Specifically, the plurality of transmission members 2 and the pressing members 1 are arranged in a circumferential array around a second fixed axis; the first fixed axis and the second fixed axis are different. Wherein the driving member 5 further comprises a rotating disc connected with the output end of the driving motor, the output end of the driving motor is eccentrically connected with the rotating disc, and the first transmission structure 21 is connected with the rotating disc, so as to realize the eccentric rotation of the plurality of pressing members 1.
[0032] Specifically, the number of the transmission members 2 and the pressing members 1 is four.
[0033] Specifically, the edge of the cutting platform 4 forms a cutting part 6, and the cutting part 6 is located below the accommodating cavity. The cutting part 6 is a sharp cutting knife.
[0034] Wherein the variable-diameter assembly 3 and the cutting platform 4 are both mounted on the agricultural track transport carrier 7, and the agricultural track transport carrier 7 adopts a tiller body or a vehicle body with a steering chassis. The agricultural track transport carrier 7 is provided with a lifting control member 8, which adopts one of a pneumatic cylinder, a hydraulic cylinder and an electric cylinder. The lifting control member 8 drives the variable-diameter assembly 3, the pressing member 1 and the cutting platform 4 to move up and down, so as to adjust the height position of the cutting platform 4, and facilitate the selection of different cutting modes. The lifting control member 8 comprises a first connecting rod 81, a second connecting rod 82, a third connecting rod 83 and a driving hydraulic cylinder 84. The third connecting rod 83 is fixed to the agricultural track transport carrier 7. One end of the second connecting rod 82 is hingedly connected to the middle part of the third connecting rod 83, and the other end is hingedly connected to the end of the first connecting rod 81. The other end of the first connecting rod 81 is hingedly connected to the cutting platform 4. One end of the third connecting rod 83 is fixed to the agricultural track transport carrier 7, and the other end is hingedly connected to the cutting platform 4. Wherein the position where the third connecting rod 83 is hingedly connected to the cutting platform 4 is different from the position where the first connecting rod 81 is hingedly connected to the cutting platform 4. The cylinder body of the driving hydraulic cylinder 84 is hingedly connected to the agricultural track transport carrier 7, and the push rod of the driving hydraulic cylinder 84 is hingedly connected to the middle part of the second connecting rod 82. The driving hydraulic cylinder 84 drives the cutting platform 4 to move up and down.
