Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to an electric tracked harvester for Hangzhou white chrysanthemums. Background Technology

[0002] Hangzhou chrysanthemum is one of the eight famous medicinal herbs of Zhejiang Province, mainly produced in Tongxiang, Zhejiang. Hangzhou white chrysanthemum is made from fresh white chrysanthemum, a perennial herb, through steaming and drying. It enjoys a reputation comparable to Longjing tea. After being brewed with boiling water, it releases a fragrant aroma and was once a tribute item. Hangzhou white chrysanthemum enters its flowering period at the end of October each year. The flowers are in tubular inflorescences. The initially sprouting buds are pale yellow, with petals curled inwards into a spherical shape, known as "fetal chrysanthemum." Dried fetal chrysanthemum flowers are neat in shape, with curled petals, a golden color, and a sweet and rich tea soup, making it a superior chrysanthemum.

[0003] Currently, the harvesting of Hangzhou white chrysanthemums in Tongxiang City is mainly done manually, accounting for 25% to 33% of the total cost. Due to rising labor costs and an aging agricultural workforce, large-scale agricultural production faces numerous challenges. In recent years, many manufacturers and research institutions have conducted extensive research on the mechanized harvesting of chrysanthemums, but existing domestic and international robots for harvesting Hangzhou white chrysanthemums are still insufficient and have not been widely adopted.

[0004] Mechanized harvesting of Hangzhou white chrysanthemum is an inevitable trend in the development of the Hangzhou white chrysanthemum industry. Existing Hangzhou white chrysanthemum harvesters mainly use comb-tooth brushes, which basically achieve the harvesting of Hangzhou white chrysanthemum. However, the comb-tooth brushes are relatively rigid, which causes serious damage to the flowers. In addition, the feeding effect of the comb teeth is not good, and the harvesting device can often be adjusted in height but not in position. Utility Model Content

[0005] Therefore, the purpose of this utility model embodiment is to provide an electric tracked tethered harvester for Hangzhou white chrysanthemums, in order to solve the problems of the current difficulty in harvesting Hangzhou white chrysanthemums by relying on manual labor, as well as the problems of existing Hangzhou white chrysanthemum harvesting machinery such as difficulty in feeding flowers, low harvesting efficiency, and serious flower damage.

[0006] According to an embodiment of the present invention, an electric tracked sling-type harvester for Hangzhou white chrysanthemums is provided, comprising:

[0018] Optionally, the picking device further includes a brush and a brush mounting plate. The brush mounting plate is fixed on the support frame, and the brush is mounted on the brush mounting plate for brushing off the Hangzhou white chrysanthemums stuck in the spring steel wire sleeve picking buckle.

[0019] Optionally, the spring steel wire sleeve buckle is composed of a pair of connecting rods and a Y-shaped sleeve frame. The pair of connecting rods are integrally formed on the upper end of the Y-shaped sleeve frame and fixed to the fixed rod by the connecting rods.

[0020] Optionally, the tracked chassis includes a chassis frame, tracks, support wheels, drive wheels, driven wheels, and a travel power device.

The harvested Hangzhou white chrysanthemum plants are conveyed by a conveyor belt into a collection box, realizing continuous harvesting of Hangzhou white chrysanthemum plants. The height of the harvesting device and its position relative to the conveyor device can be adjusted by a lifting device to adapt to the harvesting of different Hangzhou white chrysanthemum plants. This solves the problems of current difficulties in harvesting Hangzhou white chrysanthemum flowers, excessive reliance on manual labor, and the high pollution, high picking damage rate, high impurity rate, poor feeding effect, and weak endurance of some existing Hangzhou white chrysanthemum harvesters. It also creates substantial economic value and improves the mechanization of the Hangzhou white chrysanthemum industry.

[0065] Because agricultural machinery consumes a lot of energy during continuous operation and charging in the field is inconvenient, large-capacity lithium batteries 63 are often expensive and bulky. Therefore, a small-capacity lithium battery 63 is selected, and a range extender 64 is installed to extend the harvester's range and enable continuous harvesting by the electric tracked 52-type Hangzhou white chrysanthemum harvester. The range extender 64 can be installed on the side of the main frame 11.

[0066] The power unit composed of lithium battery 63 and range extender 64 provides power for continuous harvesting of Hangzhou white chrysanthemum in the field. The single-chip microcomputer 61 controls the drivers of each motor to make the harvesting, conveying, walking and height and posture adjustment of the harvesting device 3 of Hangzhou white chrysanthemum harvester more precise.

[0067] The microcontroller 61 can be connected to the display screen 62, forming a control panel for display and control.

The harvesting device 3 consists of six rows of flexible spring comb teeth evenly distributed on a disc. The Y-shaped design of the spring comb teeth facilitates the feeding of Hangzhou white chrysanthemum flowers. The roller motor 306 drives the roller shaft 301 to rotate the harvesting device 3, completing the harvesting action. After harvesting, the flowers are thrown into the conveyor belt 43. The conveyor belt 43 has partitions arranged at equal intervals. The entire conveyor belt 43 is inclined and serves as a structural support. The conveyor belt 43, driven by the motor, transports the Hangzhou white chrysanthemum flowers diagonally upwards to the collection box 12, completing the continuous harvesting of Hangzhou white chrysanthemum flowers. Two tracked chassis 5 are designed below the frame 1 as the walking mechanism of the harvesting device 3, providing strong mobility during operation. A lithium battery 63 is installed on the tracked chassis 5 to stably output voltage to the drum motor 306, the walking motor 561, the first electric push rod 25, the second electric push rod 26, and the motor built into the conveyor roller. An extender 64 is added to provide continuous power to the harvester. The microcontroller 61 in the control panel can control the forward and reverse rotation of the motors and adjust the speed. Through experiments, the optimal speed of each motor for harvesting Hangzhou white chrysanthemum can be determined, so as to achieve high-efficiency harvesting of Hangzhou white chrysanthemum with a low breakage rate, impurity rate and high feeding rate.

[0069] This invention uses a tracked chassis 5 as its walking mechanism, featuring a mechanical structure with superior passability and suspension performance to adapt to complex farmland operating environments. It maintains stability and balance across various terrains. The electric motor as the drive mechanism offers high control precision and low pollution. A comb-like arrangement of flexible spring steel wire clips 303, evenly distributed on a disc, forms the harvesting device 3, resulting in a low breakage rate during harvesting. The Y-shaped feeding mechanism of the flexible spring steel wire clips 303 improves the feeding rate of Hangzhou white chrysanthemum flowers. A conveyor belt 43 transports the harvested Hangzhou white chrysanthemum flowers into the collection box 12, completing continuous flower harvesting. A lithium battery 63 and a range extender 64 form a power unit, providing continuous power for the device's movement and harvesting. Simultaneously, a lifting device 2 allows for height adjustment of the harvesting device 3 to adapt to different environments and growth stages of the flowers. This solves the problems of the current difficulty in harvesting Hangzhou white chrysanthemum flowers, excessive reliance on manual labor, and the existing problems of large pollution, high picking damage rate, high impurity rate, poor feeding effect, and weak endurance of Hangzhou white chrysanthemum harvesters. It can also create objective economic value and improve the mechanization of the Hangzhou white chrysanthemum industry.
