Description

Technical Field

[0001] The invention relates to the technical field of wild chrysanthemum picking, in particular to a wild chrysanthemum picking flower and leaf separator. Background Art

[0002] Wild chrysanthemum is a perennial herbaceous plant of the genus Chrysanthemum in the family Asteraceae. Its flowers are arranged in sparse panicles or corymbose inflorescences, with white-brown edges and yellow ligulate flowers. Its flowers have the effects of clearing away heat and detoxifying, purging fire and calming the liver, and are an important ingredient in drugs such as Ganmaoling. In addition to its medicinal value, wild chrysanthemum flowers are also used as tea and food raw materials, with a large market demand, and have now entered the stage of artificial cultivation.

[0003] The manual harvesting of wild chrysanthemums consumes man-hours and manpower, has high labor intensity and high operating costs, which limits the development of the wild chrysanthemum industry. Therefore, the wild chrysanthemum picking process needs to be mechanized and automated to improve operating efficiency, reduce costs and the labor intensity of operators. The mechanical equipment for picking flower crops in the prior art is mainly divided into comb-tooth picking devices and drum-type picking devices. The comb-tooth picking device is suitable for the harvesting of flowers such as white chrysanthemums and tribute chrysanthemums. Due to the small difference between the diameter of the wild chrysanthemum receptacle and the diameter of the flower branches, and the irregular production of branches and leaves, serious blockage problems will occur when using the comb-tooth picking device to pick wild chrysanthemums. The drum-type picking device is more suitable for picking flowers such as cotton. The final product of flowers such as cotton is not limited by the picking quality, so it is more appropriate to use a drum-type picking device for striking and picking. Due to the uneven distribution of wild chrysanthemum flowers, when using a drum-type flower picking device to strike and pick flowers, some flower branches are prone to not being struck, and the picking rate is low. If the force of the blow is increased, the picking rate can be improved, but the flower damage rate will increase, reducing the picking quality.

[0004] In view of this, it is necessary to provide a flower and leaf separator specially used for picking wild chrysanthemum, which has the effects of high picking rate and low breakage rate. Summary of the invention

[0005] The invention aims to provide a wild chrysanthemum picking flower and leaf separator, which has the effects of high picking rate and low breakage rate.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a wild chrysanthemum picking flower and leaf separator, comprising a vehicle body, on which a harvesting part, a material bucket for receiving harvested wild chrysanthemums, and a separation cabin are installed, an entry passage is provided between the material bucket and the separation cabin device, a cabin entry conveyor belt device is installed in the entry passage, the separation cabin comprises a weighing platform, a sorting robot, a clamp for clamping wild chrysanthemum branches, a first separation part, a second separation part, a moving device that drives the clamp to pass through the first separation part and the second separation part in sequence, a third separation part, a branch conveyor belt device, a leaf conveyor belt device, and a flower conveyor belt device. The belt device comprises a visual system, and the sorting robot is used to transfer the plurality of wild chrysanthemum branches on the weighing platform to the clamper in sequence. The first separation part comprises a first vibrator device for driving the wild chrysanthemum branches clamped by the clamper to vibrate. The second separation part comprises two flower picking rollers and a plurality of bow teeth fixed to the outer wall of the flower picking roller. A flower picking gap is formed between the two flower picking rollers for the wild chrysanthemums clamped by the clamper to pass through. The third separation part comprises an upper screen arranged obliquely, and the lower end of the upper screen faces the leaf conveyor belt device. The flower conveyor belt device is located below the upper screen.

[0007] By adopting the above technical solution, the harvesting part is used to harvest the wild chrysanthemums in the planting area, and the harvested wild chrysanthemums are piled in the material bucket. The cabin conveyor belt device is used to convey the wild chrysanthemums in the material bucket to the weighing platform in the separation cabin, until the weight of the wild chrysanthemums on the weighing platform reaches the designed weight, and then the cabin conveyor belt device stops running.

[0008] The sorting robot uses a robot with a high degree of freedom. Its visual system identifies the branches of wild chrysanthemum and transfers them to the clamp. The clamp can clamp several branches of wild chrysanthemum near the root, so that the wild chrysanthemum is in an upside-down state. The mobile device drives the clamp to move, so that the wild chrysanthemum clamped by the clamp passes through the first separation part and the second separation part in sequence. When the wild chrysanthemum passes through the first separation part, the first vibrator device causes the wild chrysanthemum branches to vibrate violently, shaking off some flowers and leaves on the wild chrysanthemum, so that they fall on the third separation part. When the wild chrysanthemum passes through the second separation part, the bow teeth on the two flower picking rollers in the second separation part comb and hit the wild chrysanthemum, and the remaining flowers and some leaves fall on the third separation part. Compared with the prior art in which the wild chrysanthemum is spread on the conveyor belt device, the wild chrysanthemum in a suspended state passes through the flower picking roller, and the picking rate is higher. The wild chrysanthemums clamped by the clamper move to above the branch conveying device after passing through the first separation part and the second separation part, the clamper is released, and the branches of the wild chrysanthemums fall into the branch conveying part and are conveyed out.

[0009] The flowers and leaves falling on the third separation part pass through the mesh of the upper screen in the third separation part, fall to the flower conveyor belt device, and are transported out. The leaves cannot pass through the mesh of the upper screen, slide along the upper screen and fall to the leaf conveyor belt device, and are transported out.

[0010] The present invention realizes the separation of branches, leaves and flowers of wild chrysanthemum through the first separation part, the second separation part and the third separation part, and has a high picking rate, a low breakage rate and a low impurity rate of the flowers.

[0011] The present invention is further configured as follows: the first vibrator device includes a support fixed on the separation cabin, a movable seat one, a movable seat two, a hydraulic vibrator, and a first hydraulic cylinder, the movable seat one is installed on the hydraulic vibrator, the first hydraulic cylinder is used to drive the hydraulic vibrator to move closer to or away from the movable seat two, the support is provided with a plurality of guide holes, the movable seat two is fixed with a guide rod inserted into the guide hole, and a buffer spring is provided between the movable seat two and the support.

[0012] By adopting the above technical solution, the wild chrysanthemum clamped by the clamp enters between the movable seat one and the movable seat two, and the first hydraulic cylinder drives the hydraulic vibrator and the movable seat two to approach the movable seat one, so that the movable seat one presses the wild chrysanthemum against the movable seat two. The hydraulic vibrator runs, and the wild chrysanthemum in a suspended state vibrates violently, shaking off some flowers and leaves on the wild chrysanthemum.

[0013] The present invention is further configured as follows: the moving device comprises a slide seat slidably connected in the separation cabin, a second hydraulic cylinder device driving the slide seat to move, and the clamper is mounted and fixed on the slide seat.
