Description

Technical Field

[0001] The present invention relates to a fruit harvesting device, and more particularly to an artificial shoulder-type woody oil harvesting device and method. Background Art

[0002] During the breeding process, it's necessary to collect samples of woody oilseed plants (such as olive, camellia, and Torreya grandis) grown at different altitudes and origins. Comparing plant growth, fruiting, and nutritional composition of oilseed samples under different regional environmental conditions is crucial for collecting wild woody oilseed varieties. Harvesting woody oilseeds like camellia and olive in batches at different points in their late maturity and studying the accumulation patterns of nutrients at these different time points can pinpoint the optimal time point for the accumulation of specific nutritional activities in these late-mature woody oilseeds, allowing for the prediction and design of the most appropriate harvest period and promoting the rational implementation of industrial-scale harvesting.

[0003] Currently, there are two methods for harvesting woody oilseed samples: manual harvesting and mechanical harvesting. Manual harvesting has low efficiency and is inconvenient for harvesting woody oilseeds growing at higher locations; mechanical harvesting has poor flexibility, and many woody oilseed plants are planted in mountainous areas, which are inaccessible to mechanical equipment. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention provides an artificial shoulder-type woody oil harvesting device and method, which has good flexibility and can adapt to work on both flat land and mountainous areas, thereby facilitating the harvesting of woody oil.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: an artificial shoulder-type woody oil harvesting device, comprising a machine base carried on the shoulder, a high-pressure air pump installed in the machine base, support rods that can be flipped forward are installed on both sides of the machine base, a harvesting rod is installed on one rod, and a branch swinging mechanism is installed on the upper end of the harvesting rod; the branch swinging mechanism includes a mounting seat and a chuck, a piston chamber and an airway switching chamber are provided on the mounting seat, a piston is installed in the piston chamber, a push-pull rod is connected between the piston and the chuck, a slide is installed in the airway switching chamber, a drive rod is connected to the slide, and a push-pull mechanism is provided. A toggle head for toggling the driving rod to move back and forth is connected to the rod; an upper air hole and a lower air hole are provided on the inner wall of the piston chamber, and the upper air hole and the lower air hole are respectively arranged on both sides of the piston; an upper through hole, a lower through hole and an exhaust hole are provided on the side wall of the airway switching chamber, and the exhaust hole is arranged between the upper through hole and the lower through hole; a ventilation groove is provided on the side wall of the slide seat; the ventilation groove is connected between the upper through hole and the exhaust hole, or the ventilation groove is connected between the lower through hole and the exhaust hole; a pipeline is connected between the upper air hole and the lower through hole, and a pipeline is connected between the lower air hole and the upper through hole; the airway switching chamber is connected to the high-pressure air pump.

[0006] When the woody oil crop is harvested, the machine base is put on the shoulder, and when the woody oil crop harvesting position is reached, the supporting rod is turned down forward, the harvesting rod is held by hand, the position of the harvesting rod is adjusted, and the clamp head at the upper end of the harvesting rod is clamped on the branch. Start the high-pressure gas pump to deliver high-pressure gas flow into the airway switching cavity.

[0007] The high-pressure gas flow in the airway switching cavity enters the piston cavity through the upper through hole and the lower gas hole, pushes the piston to move upward by a distance, the pushing and pulling rod on the pushing head drives the driving rod to move upward to switch the airway, so that the air passage groove on the sliding seat is switched from being communicated between the lower through hole and the exhaust hole to being communicated between the upper through hole and the exhaust hole. At this time, the high-pressure gas flow in the airway switching cavity enters the piston cavity through the lower through hole and the upper gas hole, pushes the piston to move downward by a distance, the pushing and pulling rod on the pushing head drives the driving rod to move downward to switch the airway, and the air passage groove is switched from being communicated between the upper through hole and the exhaust hole to being communicated between the lower through hole and the exhaust hole. Repeat the above actions to realize the reciprocating movement of the piston in the piston cavity, and then realize the swinging of the clamp head on the branch, so that the woody oil crop fruits on the branch fall off to complete the harvesting.

[0008] The whole device is set in a back strap type, which is used on the shoulder, flexible and convenient, and can adapt to work whether on flat ground or in the mountains. When not in use, the supporting rod is turned up and stands on the machine base, which is convenient for walking in the mountains. The branch swinging mechanism works to swing the branches, and then the fruits on the branches fall off, which facilitates the harvesting of fruits, especially the fruits growing in high places, which is convenient and safe to harvest.

[0009] The artificial back strap type woody oil crop harvesting device has good flexibility, and can adapt to work whether on flat ground or in the mountains, which facilitates the harvesting of woody oil crops.

[0012] As a preferred, a collecting bucket is installed on the harvesting rod, and the collecting bucket has a taper structure with a large upper end and a small lower end.

[0015] When the whole device is stopped, the sliding sleeve moves away from the connecting seat under the action of the reset spring, so that the whole collecting bucket is folded, and it is convenient to store and carry. When the whole device is working, the high-pressure gas pump delivers high-pressure gas flow into the transition cavity through the gas delivery pipe, the gas pressure in the transition cavity increases to push the push plug to move, and then the sliding sleeve moves to unfold the support, so that the whole collecting bucket is unfolded to collect the woody oil plant fruits falling from the branches. After the push plug is moved to the position, the air outlet is communicated with the air inlet, the high-pressure gas flow enters the air passage switching cavity through the air pipe to drive the branch swing mechanism to work. The collecting bucket is opened before the branch swing mechanism works, so that the falling fruits are caught.

At the same time, when the collecting rod is not used, the sliding block slides to one end of the sliding groove, and the collecting rod is placed flat, so that the support rod and the collecting rod are convenient to store and place.

[0020] As preferred, the front end of the support rod is hinged with a front supporting leg, and the two sides of the base are hinged with rear supporting legs.

[0021] When working, the front supporting leg and the rear supporting leg are rotated to the vertical position to support the whole device, which is beneficial to reduce the labor intensity of the worker. When storing, the front supporting leg is rotated to the position flush with the support rod to store together, and the rear supporting leg is rotated upward to the vertical position to store.
