Description

Technical Field

[0001] The invention relates to the field of agricultural machinery picking, and in particular to a performance test bench for a flower and leaf picking device. Background Art

[0002] At present, there is no large-scale high-efficiency automatic mechanical harvester for tree-shaped and shrub-like economic plants, such as honeysuckle, chrysanthemum, etc. These traditional Chinese medicinal materials have the effects of clearing heat and detoxification, and most Chinese medicine prescriptions on the market also contain extracts of honeysuckle and chrysanthemum. The young branches and leaves of these plants can also be used as high-quality green fodder for livestock such as cattle and sheep, and with the rapid development of modern technology, many herbal tea beverages containing honeysuckle and chrysanthemum extracts have been developed, which are deeply loved by the public. And an important reason restricting the development of these economic plants is the picking problem. Therefore, the present invention designs a performance test bench for flower and leaf picking devices according to the agronomic requirements and morphological characteristics of tree-shaped and shrub-like harvesting objects, in order to verify the picking principle and explore the optimal working parameters, and lay the foundation for the development of large-scale mechanized flower and leaf picking complete machines. Summary of the invention

[0003] In view of the above technical problems, the purpose of the present invention is to provide a performance test bench for flower and leaf picking devices, thereby laying a foundation for the development of a mechanized flower and leaf picking machine.

[0004] The present invention relates to a performance test bench for flower and leaf picking devices, comprising a running wheel, a test bench frame, a motor controller, a DC motor, a cover plate, a picking device support plate, a cylindrical spike tooth, a spike tooth connecting plate, a picking belt, and a T-shaped belt. The cylindrical spike tooth, the T-shaped belt, and the spike tooth connecting plate are installed on the picking belt; the picking device is installed on the test bench frame in an inclined manner by being suspended from above and supported from below; the running wheel is installed below the test bench frame by means of bolts 2, nuts 2, and U-shaped square clips. The DC motor and the motor controller are installed on the cover plate.

[0005] The walking device includes a walking wheel support frame, bolts 2, nuts 2, walking wheels, and U-shaped square clamps. The walking wheel is installed on the walking wheel support frame composed of square steel and channel steel, and the walking wheel support frame is connected to the test bench frame through bolts 2, nuts 2 and U-shaped square clamps. The height adjustment reserved holes on the test bench frame and the U-shaped square clamps can be used to adjust the picking height and picking angle of the flower and leaf picking device.

[0006] The flower and leaf picking device is installed on the test bench frame by means of upper suspension and lower support using bolts 3, nuts 3, bolts 4, and nuts 4. Picking diameter adjustment reserved holes 1 and 2 are reserved on the two cross beams above the test bench frame, and the picking diameter of the flower and leaf picking device can be adjusted by 5cm-15cm.

[0007] The picking driving shaft is installed on the square bearing seat on the picking device support plate, the picking driven shaft is installed on the adjustable bearing seat on the picking device support plate, the picking belt is sleeved on the picking driving shaft and the picking driven shaft, and the picking belt is tensioned through the adjustable bearing seat. When the belt is tensioned, the belt support guide bar positions the picking belt on the picking driving shaft and the picking driven shaft.

[0008] The T-shaped belt is hot-melt onto the picking belt, and the spike connecting plate with cylindrical spike teeth is connected to the T-shaped belt by bolts 1 and nuts 1, so that the cylindrical spike teeth are orderly distributed on the picking belt. The cylindrical spike teeth on adjacent connecting plates are staggered, which increases the contact with the branches and improves the operating effect of the picking device.

[0009] The DC motor and the motor controller are mounted on the cover plate. The two DC motors drive the two active axes of picking to rotate inwards and relative to each other, gather the flowers and leaves to be picked into the middle of the picking device, and then the cylindrical nail teeth rotate at high speed to knock or pull the flowers and leaves off and throw them backwards. The motor controller can adjust the motor speed from 0 to 600 rpm, which can be used to explore the optimal working speed of the picking device.

[0010] The working process of the present invention is as follows:

[0011] The performance test bench of the flower and leaf picking device can move in the test field through the walking device, and the working height can be adjusted to simulate the working state of picking flowers and leaves; the flower and leaf picking device test bench has a certain inclination angle, and the test bench can ride over the plants to improve the efficiency of the operation; the speed of the picking device can be adjusted through the motor controller to explore the optimal working speed; the picking parts are composed of left and right picking heads. When the picking parts are working, the left and right picking heads rotate at high speed inward relative to each other, and the flowers and leaves are rolled into the working range of the picking device; during the rotation of the picking device, there are staggered cylindrical picking spikes on the picking device. When the combing and striking force of the cylindrical spikes on the flowers and leaves on the branches is greater than the connecting force between the flowers and leaves and the branches, the flowers and leaves are knocked down by the cylindrical spike brush and thrown backwards to complete the picking operation of the flowers and leaves.
