Description

Technical Field

[0001] The present invention relates to the technical field of picking, and particularly relates to a multifunctional green pepper picking machine and method based on stubbing. Background Art

[0002] The harvesting of Chinese prickly ash in our country mainly relies on manual labor, which not only takes a long time, has a high labor intensity, but also has low safety, high costs, and relatively low efficiency. Coupled with a short picking period and a shortage of labor, it seriously affects the picking speed, reduces the planting income, and even increases the economic risk, severely restricting the high-quality development of the Chinese prickly ash industry. At the same time, the stems and branches of Chinese prickly ash are covered with prickles, and there are also thorn protrusions on the leaf axes. Almost the entire plant has thorns. Although the plant height can be reduced through shaping and pruning, so that pickers can pick when standing, in most cases, the upper branches still need to be pulled down manually, or the inner branches need to be picked close to the main trunk, which is likely to leave scratches on the arms. Pepper farmers often pick by pinching with their fingernails when picking, which not only easily pricks the hands, but after continuous labor, the edges of the fingernails are prone to tingling and numbness due to contact with Chinese prickly ash. In addition, although the fruits of Chinese prickly ash are small, they are prone to naturally split along the cracks on their back and abdomen when mature. Their outer skins are covered with numerous wart-like oil gland dots, making it necessary to be extra careful during picking and preservation to prevent these oil gland dots from bursting. Once they burst, as the color of Chinese prickly ash darkens during the drying process, the effective ingredients inside may evaporate, greatly reducing the overall quality of Chinese prickly ash.

[0003] The existing Chinese prickly ash picking machines in China mainly include two types. One is a robotic arm with visual recognition for picking, which has an overly high manufacturing cost and still has a single-point picking mode with low efficiency, and there is no large-scale production yet; the other is a single-operator handheld Chinese prickly ash picking machine, which picks Chinese prickly ash through negative air flow or an electric brush head at the inlet end. Compared with the previous mode, the cost is greatly reduced, and the picking rate of Chinese prickly ash has been increased. However, the capacity of the handheld Chinese prickly ash picking machine is small, and when picking Chinese prickly ash into the Chinese prickly ash collection box, some Chinese prickly ash leaves will also be sucked in, affecting the screening difficulty of Chinese prickly ash; at the same time, in the first step of the separation of Chinese prickly ash particles in the existing Chinese prickly ash picking machines, gears are used, which is likely to cause crushing damage to the Chinese prickly ash particles, and there is no further separation of the Chinese prickly ash thorns and Chinese prickly ash leaves inside after the separation of Chinese prickly ash particles, resulting in unclean Chinese prickly ash particles. The fallen Chinese prickly ash branches are not further processed, which will cause a large accumulation of Chinese prickly ash branches and may cause human injury. Summary of the Invention

[0007] The above technical solutions have the following advantages or beneficial effects: In a first aspect, the present invention provides a multi-functional green prickly ash picking machine based on pile driving. In the picking device, by utilizing the functions of different rotating shafts and adjusting the speeds of the first motor and the second motor, different drums are equipped with different speeds to achieve the grasping, fixing, and picking of green prickly ash branches, thereby achieving the effect of picking green prickly ash grains. The picking of green prickly ash can be realized through simple mechanical structures and principles, reducing the cost of green prickly ash picking, making the picking of green prickly ash simpler and more convenient, and better serving the development of agriculture. The green prickly ash branches and green prickly ash grains are separated by a screening device, and then the separated green prickly ash branches and impurities are crushed by a crushing device. Large-area harvesting of green prickly ash grains can be carried out, facilitating subsequent disposal or reuse. The connection between the three parts of this device is smooth, without wasting extra labor.

[0008] Further, in the screening device, through different vibration frequencies and different sieve mesh pore sizes, under the combined action of the coarse sieve mesh and the fine sieve mesh, the green prickly ash grains can be separated from the green prickly ash leaves and some smaller green prickly ash branches.

[0009] Further, in the crushing device, the green prickly ash branches and impurities are crushed, so that the green prickly ash branches do not occupy a large amount of space, and the subsequent treatment problem of the green prickly ash branches is also solved. Not only is the effective separation of impurities achieved, but also the green prickly ash branches are ensured to be fully crushed, facilitating subsequent disposal or reuse.

[0010] Second aspect, the present invention provides a multifunctional green prickly ash picking method based on under-piling. The green prickly ash picking process relies on the core mechanism of the fruit picking device and is achieved through the collaborative operation of three rotating shafts with different structures. The entire process from grasping, pressing and shaping to hitting, the carefully designed rotation speed and tool selection ensure the high efficiency of picking and the integrity of the fruits. After the green prickly ash is picked, the green prickly ash branches and green prickly ash grains fall into the screening device for further processing together. The screening device adopts a two-layer filtering design. Through the coarse sieve mesh for the first coarse filtration, the main function is to remove the larger green prickly ash branches. Then, through the fine sieve mesh for the second fine filtration, impurities such as green prickly ash leaves and other small sundries can be screened out. Through these two layers of fine filtration, it is ensured that the finally collected are pure green prickly ash grains. At the same time, it is supported by a crank and a connecting rod, and the required power is provided by the front motor and the rear motor. After screening, the pure green prickly ash grains fall into the collection box below, thus completing the entire screening process. After being filtered by the screening device, the green prickly ash branches and impurities are guided to the crushing feed box and then slide into the tool housing for further processing. Different from the traditional sharp tools, the tool of the present invention adopts an innovative design and is divided into two parts: a T-shaped knife and a baffle to achieve higher reliability of the tool. The T-shaped knife is responsible for cutting and crushing the green prickly ash branches and impurities, and the crushed powder leaks through the middle gap. Immediately afterwards, the baffle discharges the crushed powder from the outlet smoothly through rotation, which not only realizes the effective separation of impurities, but also ensures that the green prickly ash branches are fully crushed for subsequent disposal or reuse.

[0016] The present invention also provides a multi-functional green prickly ash picking method based on under-piling, including the following steps: Step 1, start the first motor 12 and the second motor 32. The first rotating shaft 11 drives the grasping claws 13, the second rotating shaft 21 drives the pressing plate, and the third rotating shaft 31 drives the picking tube 33 to start rotating. The green prickly ash branches are grasped by the grasping claws 13, then the green prickly ash branches are pressed by the pressing plate, and then the green prickly ash branches are struck by the picking tube 33 to make the green prickly ash grains fall off; Preferably, the rotation speed of the second motor 32 is greater than the rotation speed of the first motor 12; Step 2, start the front motor 42 and the rear motor 43. The green prickly ash branches and the fallen green prickly ash grains fall onto the coarse sieve 47 for coarse filtration, obtaining green prickly ash branches and green prickly ash grains with impurities. The green prickly ash branches remain on the coarse sieve 47, and the green prickly ash grains with impurities pass through the coarse sieve 47 and fall onto the fine sieve 48 for fine filtration, obtaining impurities and pure green prickly ash grains. The impurities remain on the fine sieve 48, and the pure green prickly ash grains pass through the fine sieve 48 and fall into the collection box 41; Step 3: Start the crushing motor 53, pour the green prickly ash branches and impurities into the crushing feed box 5. The green prickly ash branches and impurities enter the inlet of the cutter housing 51 through the bottom of the crushing feed box 5, and are cut and crushed by the T-shaped cutter 65 to obtain crushed impurities.

[0017] In order to pick the green prickly ash at the lower part of the tree, this device is divided into three modules, namely the fruit picking device, the screening device and the crushing device. The fruit picking device realizes the picking of green prickly ash fruits through three kinds of rotating shafts. The screening device is the next part where the green prickly ash branches enter after the fruit picking device finishes picking the fruits. It can separate impurities such as green prickly ash branches and green prickly ash particles. The crushing device can crush impurities such as green prickly ash branches; based on the deficiencies of the existing green prickly ash picking machines, the fruit picking device of the green prickly ash picking machine is designed in the present invention. An integrated mechanism of grasping, pressing and picking is realized through different rotating shafts, which is superior to the traditional clamp-type picking. The advantage lies in the higher efficiency of this mechanism. The screening device achieves efficient results through two screenings with different sizes of sieve meshes. Different from the traditional sharp cutters, the crushing device realizes higher reliability of the cutter through high torque and high speed. One greater difference between this design and other green prickly ash picking machines based on the lower part of the tree is that the crushing of green prickly ash branches is added. The crushed green prickly ash branches and impurities will not only not occupy a large amount of space, but also can be scattered on the land. Research has shown that the crushed green prickly ash branches can improve soil fertility. Therefore, this device can also achieve green treatment.
