Description

Technical Field

[0001] This invention relates to agricultural harvesting machinery, and in particular to a harvester suitable for picking the fruits of densely planted low-growing fruit trees and its vibrating harvesting device. Background Technology

[0002] Blueberries, jujubes, grapes, and other low-bush, densely planted fruit trees have high nutritional value, are widely cultivated, and generate significant economic benefits. Currently, large-scale cultivation of these trees suffers from problems such as low harvesting efficiency and high harvesting damage due to fixed spacing, single amplitude, and non-adjustable vibration direction in the harvesting devices. Therefore, how to achieve adjustable harvesting spacing, interchangeable vibration direction, and adjustable amplitude in the vibration devices to meet the requirements of efficient and low-damage vibration harvesting of low-bush, densely planted fruit trees is a pressing issue that needs to be addressed in this field. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies of the prior art by providing a harvester and its vibrating harvesting device suitable for picking fruits from densely planted low-growing fruit trees.

[0004] To achieve the above objectives, the present invention provides a vibratory harvesting device, mounted on the frame of a harvester, comprising:

[0005] The support connection mechanism is mounted on the frame;

[0006] At least one vibrating lever mechanism is installed on the supporting connection mechanism. The vibrating lever mechanism includes symmetrically arranged vibrating levers, adjusting rods, and swinging uprights. The two ends of the adjusting rods are respectively connected to the left and right vibrating levers. Rotating the adjusting rods adjusts the angle and spacing between the left and right vibrating levers, thereby adjusting the width of the fruit branches. The swinging upright is connected to one side of the vibrating lever via the swinging rod.

[0007] A vibration drive mechanism is mounted on the frame and connected to the vibration lever mechanism.

[0008] In the aforementioned vibratory harvesting device, the vibratory lever component includes a swing plate, a vibratory beam, and a vibratory rod. The swing plate is installed at the top of the vibratory beam. The vibratory rod is evenly installed on the vibratory beam along the axial direction of the vibratory beam through a sleeve. The bottom end of the vibratory beam is provided with a swing lower pin for connecting with the support connection mechanism.

[0009] In the aforementioned vibratory harvesting device, the swing riser includes a connecting plate, an upper swing arm, a swing shaft, a deflecting riser, and a lower swing plate. The connecting plate is mounted on the upper swing arm. The two ends of the swing shaft are respectively connected to the upper swing arm and the lower swing plate. The deflecting riser is fitted onto the swing shaft. A swing connecting rod shaft is provided on the upper swing arm.

[0010] In the aforementioned vibration harvesting device, two sets of vibration lever mechanisms are arranged at the front and rear, and the two vibration lever mechanisms are connected by a vibration direction adjustment link. Both the swing link and the vibration direction adjustment link are length-adjustable rods. By adjusting the length of the swing link and the vibration direction adjustment link, the amplitude of the vibration levers at the front and rear is adjusted.

[0011] In the aforementioned vibration harvesting device, the connecting plate is provided with a co-directional vibration connecting rod shaft, and the lower swing plate is provided with a reverse vibration connecting rod shaft. When both ends of the vibration direction adjusting rod are respectively connected to the front and rear co-directional vibration connecting rod shafts, the vibration levers of the front and rear vibration lever mechanisms swing in the same direction. When both ends of the vibration direction adjusting rod are respectively connected to the front and rear reverse vibration connecting rod shafts, the vibration levers of the front and rear vibration lever mechanisms swing in opposite directions, thereby realizing the vibration direction adjustment of the front and rear vibration levers.

[0012] In the aforementioned vibration harvesting device, a drive linkage shaft is further provided on the lower swing plate of the swing riser of the rear vibration lever mechanism, and the vibration driving mechanism is connected to the drive linkage shaft.

[0013] In the aforementioned vibratory harvesting device, the supporting connection mechanism includes a vertical bearing seat and a rhomboid spherical bearing seat, which are respectively mounted on the frame. The upper end of the vibratory lever is connected to the vertical bearing seat, and the lower end of the vibratory lever is connected to the rhomboid spherical bearing seat.

[0014] In the aforementioned vibration harvesting device, the vibration driving mechanism includes a drive motor and a transmission mechanism. The drive motor is mounted on one side of the frame via a motor connecting plate. The transmission mechanism is connected to both the drive motor and the swing riser.

[0015] The aforementioned vibratory harvesting device includes a transmission mechanism comprising a large sprocket, a small sprocket, a roller chain, and a drive linkage. One end of the drive linkage is connected to the eccentric swing shaft of the large sprocket, and the other end is connected to the rear swing riser. The small sprocket is mounted on the motor connecting plate via a bearing and connected to the output shaft of the drive motor. The roller chain is tensioned on the large and small sprockets. The drive motor drives the rear swing riser to move via the drive linkage. The rear swing riser drives the front swing riser to move via the vibration direction adjustment linkage. The front and rear swing risers respectively drive the front and rear vibration levers to vibrate via corresponding swing linkages, thereby achieving efficient vibratory harvesting of fruits from densely planted low-growing fruit trees.

[0016] To better achieve the above objectives, the present invention also provides a harvester, which includes the above-described vibratory harvesting device.

[0017] The technical effects of this invention are as follows:

[0018] This invention is applicable to the vibration harvesting of fruits from low-bush, densely planted fruit trees such as blueberries, jujubes, and grapes. The vibration harvesting device is powered by a drive motor. The vibration direction adjustment linkage is installed in different positions to achieve the same-direction and opposite-direction vibration effects of the front and rear rows of levers. The adjustment linkage can adjust the angle and spacing of the left and right vibrating levers in the same row to achieve vibration harvesting of fruit branches of different sizes from low-bush, densely planted fruit trees. The left and right vibrating levers in the same row vibrate at high speed to beat the fruit branches to be harvested, achieving efficient vibration harvesting of fruit branches. The amplitude, vibration direction, and vibration frequency are all adjustable.

[0072] This invention is applicable to the harvesting of fruits from low-bush, densely planted fruit trees such as blueberries, jujubes, and grapes. It is driven by a hydraulic motor and uses a multi-row arrangement of vibrating levers. The spacing, vibration direction, and amplitude of the vibrating levers are adjustable, which increases the number of vibrations on the fruit branches and the harvesting rate, thus broadening the applicable scope of the harvester and achieving efficient vibration harvesting of fruits from low-bush, densely planted fruit trees such as blueberries, jujubes, and grapes.
