Embodiment 1

[0029] Embodiment one, see figure 1 , a negative pressure suction picking fixed way drop type fruit picking mechanism, including a support rod 1. The support rod 1 is provided with a fruit drop channel 2 extending in the vertical direction and passing through the support rod. The upper end of the strut 1 is sequentially provided with a material inlet 3 and an air hole 4 from top to bottom. The material inlet 3 is arranged at the end of the strut 1 and communicates with the fruit drop channel 2 .

[0030] Feeding port 3 is arranged vertically. The free end of feed inlet 3 is upper end among the figure and is provided with blade 5. The blade 5 is serrated and extends along the circumference of the feed port 3 to fill the feed port. The teeth constituting the blade 5 are flat teeth.

[0031]The feeding port 3 and the fruit drop channel 2 are located on a straight line. It can improve the compactness of the structure and the patency of the fruit when it enters the fruit fall...

Embodiment 2

[0041] Embodiment two, see figure 2 , the difference with Embodiment 1 is:

[0042] The lower end of the fruit drop passage 2 is provided with a buffer plate 14 and a resetting machine 15 .

[0043] The buffer plate 14 is a grid plate. The grid panels are designed so as not to interfere with the rise of the airflow.

[0044] The buffer plate 14 is hinged on the inner surface of the barrel body 101 through the hinge shaft 16 .

[0045] The reset mechanism 15 is a torsion spring sleeved on the hinge shaft 16 .

[0046] An energy-absorbing structure 17 is provided on the upper side of the buffer plate 14 . The energy-absorbing mechanism 17 is a grid-shaped sponge pad.

[0047] During the fruit picking process, when the fruit falls along the fruit drop channel 2 and touches the buffer plate 14, the energy-absorbing mechanism 17 absorbs the part of the impact force when the fruit falls to reduce the damage to the fruit, and the buffer plate 14 goes downward. Opening allows t...

Embodiment 3

[0048] Embodiment three, see image 3 , The difference with the second embodiment is: the buffer plate 14 is arranged in the lower end of the fruit descending passage 2. A rotating shaft 141 is disposed on the buffer plate 14 .

[0049] The reset mechanism 15 includes a motor 151 electrically connected together, a fruit detection electric eye 152 arranged on the inner wall of the pole 1 and a control unit (the control unit is not shown in the figure). The power output shaft of the motor 151 is connected with the rotating shaft 141 .

[0050] The energy-absorbing structure 17 includes a rubber layer 171 and a supporting spring 172 . The rubber layer 171 is provided with ventilation holes aligned with the grid holes on the buffer plate 14 . The rubber layer 171 is supported on the grid plate 14 by a support spring 172 .

[0051] When the fruit descends along the fruit drop channel 2 and touches the buffer plate 14, the energy-absorbing mechanism 17 absorbs part of the impact...

Abstract

The invention relates to the field of fruit picking, in particular to a fixed-channel falling type fruit picking mechanism with negative-pressure suction picking. The fixed-channel falling type fruit picking mechanism comprises a supporting rod and an airflow converging cavity. A fruit falling channel is formed in the supporting rod, extends in the length direction of the supporting rod and penetrates through the supporting rod. A fruit inlet is formed in the upper end of the supporting rod and communicated with the fruit falling channel. A blade is arranged on the fruit inlet, and the supporting rod is provided with multiple air holes communicated with the fruit falling channel and the airflow converging cavity. The airflow converging cavity is provided with an air outlet connected with a vacuum generator. The fixed-channel falling type fruit picking mechanism with negative-pressure suction picking and a method with negative-pressure suction picking are provided, wherein the fixed-channel falling type fruit picking mechanism and method are small in fruit damage in the process of separating the fruit from a fruit tree and saves labor in the process of collecting the fruit. The problems that in the process of separating the fruit from the fruit tree, fruit damage is severe, and time and labor are wasted in the process of collecting the picked fruit are solved.

Description

technical field [0001] The invention relates to the field of fruit picking, in particular to a fruit picking mechanism and a fruit picking method of a negative pressure suction picking fixed path drop type fruit picking method. Background technique [0002] The original method of picking fruits such as red bayberry and hickory is to manually climb up the fruit tree and pick the fruits by hand or sticks. Artificial climbing to pick fruit has the disadvantages of low picking efficiency, great difficulty, and high risk, and casualties caused by climbing and picking sometimes occur. In order to overcome the problem of poor safety of artificial climbing and picking, a fruit picking device capable of picking fruits on trees on the ground has been designed. [0003] For example, Chinese Patent No. is 942369254, the date of authorization announcement is June 21, 1995, and the patent document called "fruit picker" discloses a device that can pick fruits on trees on the ground. The ...
