Description

Technical Field

[0001] The utility model belongs to the technical field of fruit picking tools, in particular to a high-branch fruit picking device. Background Art

[0002] To harvest fruits from tall trees, the assistance of a fruit picking device is often required. For example, a multi-fruit picking auxiliary device disclosed in Chinese patent document CN108718696A includes a hand-held rod, a picking head and a shearing device located at the upper end of the hand-held rod, a camera for real-time reflection of the situation of fruits on the tree, a conveying pipe for conveying fruits, a mobile phone fixing bracket and a pulling device for fixing and mounting a mobile phone, wherein the mobile phone fixing bracket is installed on the hand-held rod, and the camera is connected to the mobile phone. This solution can improve the efficiency of picking fruits at high altitudes, but in its shearing mode, the fruit stalk needs to be stuck into the V-shaped notch, and then the scissors need to be opened and closed by pulling the wire, which is relatively inconvenient to operate, while its picking mode is easy to clamp the branches and leaves around the fruit, and pull the branches and leaves together.

[0003] The technical solution proposed in Chinese patent document CN108307794A is conducive to improving the above problems. It discloses an automatic fruit picking device, including a device body with universal wheels, a fruit storage box and a telescopic rod are arranged on it, a placement groove is arranged on the top of the telescopic rod, a sponge buffer block is fixedly installed on the inner wall of the placement groove, and a scissors are located on the top of the inner wall of the placement groove. By pressing the driving button, the driver drives the scissors to cut the fruit, and the fallen fruit flows into the fruit storage cavity along the pipeline. Although this solution can further reduce the labor intensity of manual labor and improve the convenience of operation, the cutting of the scissors is easy to damage the fruit and the branches and leaves around the fruit.

[0004] There are also non-scissor-type cutting heads in the prior art, such as the solution disclosed in CN107493829A, which has a strip cutting opening designed on the top of the cylindrical shell. The user uses the cutting opening to place the branch part of the upper end of the fruit between two saw blades. Under the cutting action of the saw blades, the fruit is cut off and falls into the feed hopper. In this solution, since the branches of the fruit are prone to horizontal shaking, it is actually difficult to buckle the strip cutting opening into the fruit branches; secondly, it is also easy to get adjacent branches stuck in the strip cutting opening, causing damage to irrelevant branches. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present application proposes a high-branch fruit picking device, which improves the picking efficiency while reducing the probability of damage to surrounding fruits, branches, and leaves.

[0006] The solution of the utility model to solve the technical problem is:

[0007] The high-branch fruit picking device comprises a hand-held rod, a picking head located at the upper part of the hand-held rod, and a buffer conveying pipe connected to the picking head. The picking head has a shearing tool. The hand-held rod is provided with a branch fork at the top thereof. The picking head is fixed to the upper part of the hand-held rod through a picking arm. The picking head is in the shape of a flat plate, on which a fruit entrance is provided. The shearing tool is a blade equipped with a blade driving mechanism. The shearing tool can move along the plane where the fruit entrance is located under the drive of the blade driving mechanism. The picking arm and the blade driving mechanism are controlled by a control platform.

[0008] The invention concept of this application is: using the cooperation of the branch fork and the picking arm, the branches full of fruits are forked and picked, so that the fruits are exposed above the tree crown, which is convenient for the picking head to take the fruits one by one. Secondly, the structure of the picking head is improved to be flat, which is conducive to blocking the branches and leaves around the fruit from entering the fruit entrance. When the fruit enters the fruit entrance, the blade moves along the plane where the fruit entrance is located to cut off the fruit stem, which is simple and easy to operate.

[0009] As an improvement, the blade drive mechanism includes a push rod connected to the shearing tool, the push rod is driven by a push rod motor, the picking arm has a picking head connecting piece for fixing the picking head, the push rod motor and part of the push rod are located inside the picking head connecting piece.

[0010] As an improvement, the picking arm has a horizontal adjustment joint and a vertical adjustment joint, and the horizontal adjustment joint and the vertical adjustment joint are respectively controlled by a steering gear, and the steering gear is controlled by the control platform.

[0011] As a further improvement, a camera is provided on the picking head, and the control platform is equipped with a display screen for displaying images taken by the camera.

[0012] As a further improvement, a platform fixing bracket for fixing the control platform is provided at the lower part of the hand-held rod.

[0013] As an improvement, the hand-held rod is a telescopic rod so that its length is adjustable.

[0014] As an improvement, the buffer delivery pipe is a corrugated pipe.

[0015] As a further improvement, the buffer conveying pipe is assembled from a plurality of sections of corrugated pipes, which is helpful to slow down the falling speed of the fruit.

[0016] As an improvement, the buffer conveying pipe is connected to a fruit storage bin, which is a bin body with rollers at the bottom, and the fruit storage bin is equipped with a push rod.

[0017] As a further improvement, a buffer cavity is provided at the connection between the fruit storage bin and the buffer conveying pipe, the buffer cavity has an elastic buffer wall directly opposite to the bottom end of the buffer conveying pipe, the bottom of the buffer cavity is a fruit outlet, and a guide sheet is provided at the fruit outlet. The buffer cavity is conducive to further reducing the speed at which the fruit enters the fruit storage bin, and the fruit is not easily damaged.

[0018] To sum up, the utility model has the characteristics of novel design and practical functions. While improving the picking efficiency, it reduces the probability of damage to fruits, branches and leaves, and is also conducive to improving the comfort of the picking process.
