Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a movement mode in which wine grapes interact with air force and an air suction type harvesting device. Background Art

[0002] my country ranks second in the world in grape cultivation area, resulting in a massive grape production. Once ripe, wine grapes must be harvested promptly to minimize yield. Harvesting wine grapes is labor-intensive and timeliness is crucial. With rising labor costs and labor shortages in China, the problems of delayed and costly wine grape harvesting are becoming increasingly serious. The mechanization of wine grape harvesting is crucial for the industrial development of China's grape industry and for increasing farmers' incomes.

[0003] There are very few types of wine grape harvesting machinery available domestically and internationally, and most of them are vibrating. Vibrating wine grape harvesters use a crank-rocker mechanism to beat the grape branches and bunches, causing the grape berries to fall off due to vibration. The disadvantages of this type of wine grape harvesting machinery are: on the one hand, due to the different wine grape planting patterns at home and abroad, vibrating wine grape harvesters have difficulty in causing resonance in grapes grown under single-arm trellis planting patterns, making it difficult for the berries to fall off and resulting in poor harvesting results; on the other hand, the beating of the crank-rocker mechanism can cause serious berry breakage, resulting in losses and affecting the economic benefits of growers. For these reasons, the harvesting of wine grapes in China is still almost entirely manual, and there is an urgent need for a new type of wine grape harvesting machinery. Summary of the Invention

[0004] Using pneumatic harvesting causes less damage to crops and has a fast adsorption speed, making it a potential development direction for wine grape harvesting machinery.

The length of the pull rod on the traction beam 2 and the height of the depth-limiting wheel 4 are adjusted to make the machine at an appropriate height so that the suction end can contact the grapes; the second pull rod 73 is adjusted so that the rubber tire 70 mounted on the rolling conveyor belt 68 contacts the ground; one operator sits on the first seat 9 to replace the fruit baskets, and the other operator sits on the second seat 63 to control the suction end.

[0133] During operation, the tractor pulls the implement forward; the diesel engine 16 is turned on to provide power to the fan 13, so that negative pressure is generated at the air inlet of the fan 13; the fan 13 device, the dual-channel collection box device, and the adsorption terminal device are connected by a negative pressure pipe, which together constitute an adsorption system; the operator controls the adsorption terminal device to approach the grapes. On the one hand, the adsorption terminal device can slide on the hanging rail 64 through the bearing hanging wheel 50, extend and retract in the horizontal direction, and on the other hand, it can be raised and lowered in the vertical direction through the linear bearing 52; the adsorption terminal device adsorbs the grapes on the branches through the suction force generated by the negative pressure system, and the grapes are deflected by the adsorption effect, and part of them are sucked into the adsorption terminal device; the adsorption terminal device cuts off the fruit stems through the cutting device 46; then the grapes are transported to the dual-channel collection box device; inside the dual-channel collection box device, the upper blade 41 is in contact with one side of the box wall In the embodiment of the present invention, one of the lower blades 42 is in a horizontal state and the other is in a vertical state. The upper blades 41, the lower blades 42 in a horizontal state and the box body 19 together constitute a sealed collecting channel. The transported grapes are temporarily stored in the collecting channel and fall on the lower blades 42 in a horizontal state. The blades in the box body 19 rotate periodically. The upper blades 41 rotate toward the other side of the box body 19, the lower blades 42 in a horizontal state turn to a vertical state, and the lower blades 42 in a vertical state turn to a horizontal state, forming a new sealed collecting channel. In this process, the grapes previously collected are released due to the rotation of the lower blades 42. The grapes released by the dual-channel collecting device are transported to the fruit frame 75 by the conveyor belt 66. After the fruit frame 75 is full of grapes, the operator transports the fruit frame 75 to the ground through the rolling conveyor belt 68 to facilitate subsequent transfer and transportation.

[0134] It should be noted that the present invention also proposes a method for the movement of wine grapes that interacts with air forces. When airflow contacts the wine grapes, it imparts an airflow force to the grapes. Under the influence of the airflow force, the wine grapes growing on the fruiting branches are deflected around the connection point between the fruit stem and the fruiting branch. The wine grapes in the negative pressure pipe are transported under the influence of the airflow force. After the airflow interacts with the wine grapes, the flow rate decreases, and the airflow force is reduced. Based on the above, the harvesting method is as follows: the air suction harvesting device first uses negative pressure to absorb the wine grapes based on the interaction between the wine grapes and air forces, causing the wine grapes to shift from their original vertical position to a horizontal position and pull them away from the fruiting branches, freeing them from being obstructed by the fruiting branches. The grapes are then cut with a knife and fall into the negative pressure pipe. The wine grapes are then transported to a collection device under the influence of the air force in the negative pressure pipe for collection. In the single-arm trellis planting mode, the wine grapes fruit at a height of 70 cm above the ground, and the coefficient of variation in fruiting height between different fruiting branches and between different fruit trees is low. The air-suction harvesting device moves along the trellis at the fruiting height of the wine grapes, and continuously repeats the above process until the wine grape harvesting operation is completed.

Persons skilled in the art may make various changes and modifications without departing from the essence and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of protection of the present invention shall be defined by the claims. Matters not described in detail in this specification constitute prior art known to those skilled in the art.
