For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] Please refer to Figures 1 to 8 The utility model provides a fruit feeding mechanism, including foot stool 1, climbing conveyor 2, hopper 3, pushing device 4 and brushing device 5, climbing conveyor 2 with foot stool 1 is connected, hopper 3 is located in the feeding one end of climbing conveyor 2, pushing device 4 is located at the bottom of hopper 3, and it is used to push the material 7 in hopper 3 into climbing conveyor 2, brushing device 5 is located on climbing conveyor 2, and it is used to brush the extra fruit on climbing conveyor 2 and fall into hopper 3.

[0028] In the embodiment of the utility model, foot stool 1 provides stable support for the whole mechanism, climbing conveyor 2 can lift fruit from low place to the required position, realizes automatic feeding, improves work efficiency and reduces the workload of manual handling. The climbing conveyor 2 in the embodiment is a structure of one section of inclined conveying and one section of horizontal conveying, the inclined conveying part realizes the lifting of fruit, and the horizontal conveying part drives the movement of fruit in the horizontal direction. Hopper 3 is arranged at the feeding end of climbing conveyor 2, after the material 7 is put into hopper 3, hopper 3 can store a certain amount of fruit, due to the inclined structure of climbing conveyor 2, the fruit is automatically collected at the bottom of hopper 3 under the action of self weight, and then is lifted by climbing conveyor 2.

[0029] In actual production, fruit is prone to empty package at hopper 3 due to self-arch bridge effect. The self-arch bridge effect refers to the phenomenon that a stable arch structure is formed at the outlet of hopper 3, pipeline or other conveying device in the process of processing granular material 7 due to the interaction force between particles and external force. Different kinds of fruit have different shapes and sizes, and some fruit is rough and irregular in shape, and due to the interaction between fruit and the friction between the fruit and the container wall, a blockage is formed on the outlet or conveying path, and an arch structure phenomenon is easily formed on hopper 3. Therefore, the pushing device 4 is arranged at the bottom of hopper 3 in the embodiment, the pushing device 4 is used to push or vibrate the fruit to destroy the formed arch bridge and restore the fluidity of the fruit, so that the fruit is more easily put into climbing conveyor 2 and the occurrence of empty package is reduced.

[0030] Because fruit is prone to accumulation, multiple fruits may be simultaneously carried on climbing conveyor 2, especially when the sizes of fruit are different, which easily leads to the clamping of multiple fruits in one station. Therefore, the brushing device 5 is arranged on climbing conveyor 2 in the embodiment, the brushing device 5 brushes the extra fruit on climbing conveyor 2 and falls into hopper 3, avoiding that the extra fruit destroys the subsequent packaging process and affects the normal operation of the equipment.

[0031] The working process of the embodiment is as follows: the fruits are placed in the hopper 3, which temporarily stores the fruits and provides the source of the material 7 for subsequent feeding; the pushing device 4 starts to work and pushes the fruits in the hopper 3 to the climbing conveyor 2, so that the fruits can enter the conveying track of the climbing conveyor 2; the climbing conveyor 2 operates under the driving of the power and conveys the fruits upward along the inclined track, realizing the automatic feeding process of the fruits and conveying the fruits to the designated position; during the conveying process of the climbing conveyor 2, if the fruits are accumulated or the position is inaccurate, the brushing device 5 will brush off the excess fruits, so that the fruits return to the hopper 3, thereby ensuring the smoothness and stability of the fruit conveying on the climbing conveyor 2.

[0032] Preferably, the pushing device 4 comprises a gear reduction motor 41, an eccentric wheel 42, a connecting rod 43, a push plate 44 and a rotating shaft 45; the push plate 44 is connected with the rotating shaft 45 and rotatably connected with the hopper 3 through the rotating shaft 45; the output end of the gear reduction motor 41 is connected with the eccentric wheel 42, one end of the connecting rod 43 is rotatably connected with the eccentric wheel 42, and the other end is rotatably connected with the push plate 44. In the embodiment, the gear reduction motor 41 can provide stable and adjustable power, which can convert the rotary motion of the motor into the eccentric motion of the eccentric wheel 42 by being connected with the eccentric wheel 42. The push plate 44 is rotatably connected with the hopper 3 through the rotating shaft 45, so that the push plate 44 can swing flexibly within a certain angle range. By cooperating the eccentric wheel 42 with the connecting rod 43, the circumferential motion of the eccentric wheel 42 can be converted into the reciprocating swing of the push plate 44, so that the fruits at the bottom of the hopper 3 can be effectively pushed to the climbing conveyor 2. This transmission mode is simple and reliable, and can accurately control the motion track and rhythm of the push plate 44, realize the repeated pushing of the fruits in the hopper 3, and reduce the self-arching effect of the fruits. Further, the pushing frequency and strength of the push plate 44 can be controlled by adjusting the motor speed and other ways according to the accumulation of the fruits and the feeding demand, so as to ensure the smoothness and efficiency of the feeding.

The driving shaft 224 starts to rotate under the drive of the worm reducer 222, since the driving sprocket 232 is drivingly connected with the worm reducer 222 through the driving shaft 224, the driving shaft 224 drives the driving sprocket 232 to rotate together, and then drives the conveying chain 231 to move, so as to realize the material 7 conveying function of the fruit feeding mechanism.

[0037] Preferably, the inner walls on both sides of the rack 21 are provided with guide assemblies matched with the two chain transmission assemblies 23; the guide assemblies comprise a first guide plate 26, a second guide plate 27, a third guide plate 28 and a fourth guide plate 29; the roller 24 comprises a rolling part 241, both ends of the rolling part 241 are respectively provided with cam parts 242, the cam parts 242 are provided with pin shafts 243, and the chain transmission assemblies 23 are connected through the pin shafts 243; when the roller 24 moves, the cam parts 242 pass through the first guide plate 26, the second guide plate 27, the third guide plate 28 and the fourth guide plate 29 in sequence.

[0038] The guide assemblies provided on the inner walls on both sides of the rack 21 can provide accurate guiding effect for the chain transmission assemblies 23. During the movement of the roller 24, the cam parts 242 pass through the first guide plate 26, the second guide plate 27, the third guide plate 28 and the fourth guide plate 29 in sequence, so that the roller 24 and the chain transmission assemblies 23 connected therewith can only move along a specific track, the device can still remain stable when it runs at high speed or bears a large weight of fruits, the problems of deviation and shaking of the chain during movement are effectively avoided, the probability of failure of the device due to shaking or vibration is reduced, and the service life of the device is prolonged.
