Description

Technical Field

[0001] This invention relates to the field of harvesting technology, specifically to a multifunctional green pepper harvesting machine and method based on pile driving. Background Technology

[0002] In my country, the harvesting of Sichuan pepper mainly relies on manual labor, which is not only time-consuming and labor-intensive, but also unsafe, costly, and relatively inefficient. Coupled with a short harvesting period and labor shortages, this severely impacts harvesting speed, reduces planting profits, and even increases economic risks, seriously hindering the high-quality development of the Sichuan pepper industry. Furthermore, the stems and branches of Sichuan pepper are covered with thorns, and the leaf axes also have thorns; almost the entire plant is covered in thorns. Although pruning can reduce plant height, allowing harvesters to pick the peppers while standing, in most cases, it is still necessary to manually pull down the upper branches or pick the inner branches close to the main trunk, which easily leaves scratches on the arms. Pepper farmers often use their fingernails to pinch off the peppers during harvesting, which not only easily pricks their hands, but after continuous labor, the edges of their fingernails are prone to stinging and numbness from contact with the peppers. In addition, although the fruit of Sichuan pepper is small, it is easy to split open naturally along the seams on its back and abdomen when it is ripe. Its outer skin is covered with many wart-like oil glands, which makes it necessary to be extra careful when harvesting and storing it to prevent these oil glands from breaking. Once they break, as the color of the Sichuan pepper darkens during the drying process, the effective ingredients inside may evaporate, which will greatly reduce the overall quality of the Sichuan pepper.

[0003] The two main types of pepper harvesting machines currently in use in China are: one type uses a robotic arm with added visual recognition for harvesting, but this is too expensive to manufacture and still operates on a single-point harvesting model, resulting in low efficiency, and has not yet been widely deployed; the other type is a handheld pepper harvesting machine operated by a single person, which uses negative airflow or an electric brush head at the inlet to harvest peppers, significantly reducing costs compared to the former and increasing the harvesting speed. However, the handheld harvesting machine has a small capacity, and some pepper leaves are sucked in when the peppers are picked and placed into the pepper collection box, making it difficult to sift the peppers. In addition, the existing pepper harvesting machines use gears for the first step of separating the pepper kernels, which can easily cause crushing damage to the pepper kernels. Furthermore, the pepper thorns and leaves inside the pepper kernels are not further separated, resulting in unclean pepper kernels. The fallen pepper branches are also not further processed, causing a large accumulation of pepper branches, which may cause human damage. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional green Sichuan pepper harvesting machine and method based on pile foundation, in order to overcome the problems existing in the prior art. This invention can realize functions such as harvesting, screening, and crushing branches. The fruit picking device enables green Sichuan pepper branches to enter the device for harvesting, the screening device filters out pure green Sichuan pepper grains, and the crushing device crushes the green Sichuan pepper branches. This invention integrates harvesting, screening, and crushing branches, thereby systematically realizing the entire process of green Sichuan pepper harvesting.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, the present invention provides a multi-functional green pepper harvester based on a pile, including a fruit picking device, a screening device installed on one side of the fruit picking device, and a crushing device installed on one side of the screening device.

[0007] The fruit-picking device includes a fruit-picking frame, with a fruit-picking shell installed on the top of the frame. A first picking unit, a second picking unit, and a third picking unit are sequentially installed on the front of the fruit-picking shell from the distance from the screening device to the distance from the screening device via a fixed plate. Each of the three picking units includes a first rotating shaft, a second rotating shaft, and a third rotating shaft, respectively. All three shafts penetrate the fixed plate and the front of the fruit-picking shell, extending to the rear inner wall of the shell. A first motor is installed at one end of the first and second rotating shafts located at the front of the fixed plate, and a second motor is installed at one end of the third rotating shaft. Several gripping claws are installed on the first rotating shaft inside the fruit-picking shell, several pressing plates are installed on the second rotating shaft inside the shell, and several picking tubes are installed on the third rotating shaft inside the shell.

[0008] Furthermore, the screening device includes a screening support located on one side of the fruit shell, a collection box installed at the bottom of the screening support, a crushing device installed on one side of the collection box, a front motor installed on the front inner wall of the screening support, a rear motor installed on the rear inner wall, and connecting rods installed on the front and rear motors respectively via cranks. The connecting rods include a first connecting rod and a second connecting rod. The two cranks pass through the front and rear parts of the screening support respectively and are connected to the front and rear motors. One end of the first connecting rod is connected to the crank and the second connecting rod, and the other end is fitted with a coarse screen through a first moving hole. One end of the second connecting rod is connected to the first connecting rod and the crank, and the other end is fitted with a fine screen through a second moving hole. The fine screen and the coarse screen are located inside the screening support, with the fine screen located at the bottom of the coarse screen.

[0009] Furthermore, the crushing device includes a crushing feed box installed on one side of the collection box. The crushing feed box is located at the bottom of the fine screen. A crushing blade is installed on one side of the bottom of the crushing feed box. The crushing blade includes a blade housing. An inlet connected to the bottom of the crushing feed box is opened at the rear of the blade housing. An outlet is opened at the top of the blade housing. A blade is installed inside the blade housing. A crushing motor is installed at the front of the blade housing. The crushing motor includes a crushing shaft. A crushing coupling is installed on the crushing shaft. The crushing motor is connected to the blade through the crushing coupling.

[0010] Furthermore, the cutting tool includes a blade with a shaft hole in the middle, which is connected to the crushing shaft. The outer ring of the shaft hole also has several screw holes, which are connected to the crushing coupling. The blade also has symmetrical arc-shaped openings for allowing crushed impurities to pass through. Several T-shaped blades are installed on one side of the blade, and several baffles are installed on the other side.

[0011] Furthermore, the first motor is connected to the first shaft and the second shaft via a first coupling; the second motor is connected to the third shaft via a second coupling; bearings are also installed on the first shaft, the second shaft and the third shaft; the pressure plate includes a pressure plate bracket installed on the second shaft, and a pressure plate is installed on the top of the pressure plate bracket.

[0012] Secondly, the present invention provides a multifunctional green Sichuan pepper harvesting method based on stakes, which, based on the above-mentioned multifunctional green Sichuan pepper harvesting machine based on stakes, includes the following steps:

[0013] The first picking unit grabs the green pepper branches, the second picking unit presses the green pepper branches down, and the third picking unit strikes the green pepper branches to cause the green pepper particles to fall off.

[0014] The green pepper branches and fallen green pepper particles fall into the screening device, where they are coarsely filtered to obtain green pepper branches and green pepper particles with impurities. The green pepper particles with impurities are then finely filtered to obtain impurities and pure green pepper particles.

[0015] The green pepper branches and impurities are crushed using a crushing device;

[0016] Furthermore, the process of grasping the Sichuan pepper branches through the first harvesting unit, pressing the branches down through the second harvesting unit, and then striking the branches with the third harvesting unit to dislodge the Sichuan peppercorns specifically includes:

[0017] Start the first and second motors. The first rotating shaft drives the gripping claw, the second rotating shaft drives the pressing plate, and the third rotating shaft drives the picking tube to start rotating. The gripping claw grabs the green pepper branches, the pressing plate presses the green pepper branches, and the picking tube hits the green pepper branches to make the green pepper particles fall off.

[0018] Furthermore, the second motor has a higher rotational speed than the first motor;

[0019] Furthermore, the screening device includes a screening support located on one side of the fruit shell, a collection box installed at the bottom of the screening support, a crushing device installed on one side of the collection box, a front motor installed on the front inner wall of the screening support, a rear motor installed on the rear inner wall, and connecting rods installed on the front and rear motors respectively via cranks. The connecting rods include a first connecting rod and a second connecting rod. The two cranks pass through the front and rear parts of the screening support respectively and are connected to the front and rear motors. One end of the first connecting rod is connected to the crank and the second connecting rod, and the other end is fitted with a coarse screen through a first connecting hole. One end of the second connecting rod is connected to the first connecting rod and the crank, and the other end is fitted with a fine screen through a second connecting hole. The fine screen and the coarse screen are located inside the screening support, with the fine screen located at the bottom of the coarse screen.

[0020] The Sichuan pepper branches and fallen Sichuan peppercorns fall into a screening device, where they undergo coarse filtration to obtain Sichuan pepper branches and Sichuan peppercorns containing impurities. The Sichuan peppercorns containing impurities then undergo fine filtration to obtain impurities and pure Sichuan peppercorns. Specifically, this includes:

[0021] Before starting the front motor and the rear motor, the green pepper branches and fallen green pepper particles fall onto the coarse screen for coarse filtration, resulting in green pepper branches and green pepper particles with impurities. The green pepper branches remain on the coarse screen, while the green pepper particles with impurities pass through the coarse screen and fall onto the fine screen for fine filtration, resulting in impurities and pure green pepper particles. The impurities remain on the fine screen, while the pure green pepper particles pass through the fine screen and fall into the collection box.

[0022] Furthermore, the pulverizing device includes a pulverizing feed box installed on one side of the collection box. The pulverizing feed box is located at the bottom of the fine screen. A pulverizing blade is installed on one side of the bottom of the pulverizing feed box. The pulverizing blade includes a blade housing. An inlet connected to the bottom of the pulverizing feed box is opened at the rear of the blade housing. An outlet is opened at the top of the blade housing. A blade is installed inside the blade housing. A pulverizing motor is installed at the front of the blade housing. The pulverizing motor includes a pulverizing shaft. A pulverizing coupling is installed on the pulverizing shaft. The pulverizing motor is connected to the blade through the pulverizing coupling. The blade includes a blade. A shaft hole is opened in the middle of the blade. The shaft hole is connected to the pulverizing shaft. Several screw holes are also opened on the outer ring of the shaft hole. The screw holes are connected to the pulverizing coupling. The blade also has symmetrical arc-shaped openings for passing through the pulverized impurities. Several T-shaped blades are installed on one side of the blade. Several baffles are also installed on the other side.

[0023] The process of crushing the Sichuan pepper branches and impurities using a crushing device specifically includes:

[0024] Start the crushing motor and feed the Sichuan pepper branches and impurities into the crushing feed box. The Sichuan pepper branches and impurities enter the inlet of the blade housing through the bottom of the crushing feed box. The T-shaped blade cuts and crushes the Sichuan pepper branches and impurities to obtain crushed impurities. The crushed impurities pass through the blade through the arc-shaped opening and are then conveyed to the outlet of the blade housing by the baffle.

[0025] The above technical solution has the following advantages or beneficial effects:

[0026] Firstly, this invention provides a multi-functional Sichuan pepper harvesting machine based on a pile foundation. The harvesting device utilizes different rotating shafts, and through the speed control of the first and second motors, different rollers are equipped with different speeds to grasp, fix, and harvest Sichuan pepper branches, thereby achieving the effect of harvesting Sichuan pepper granules. It can harvest Sichuan pepper using a simple mechanical structure and principle, reducing the cost of Sichuan pepper harvesting and making it simpler and more convenient, better serving agricultural development. A screening device separates the Sichuan pepper branches and granules, and a crushing device further crushes the separated branches and impurities, enabling large-scale harvesting of Sichuan pepper granules, facilitating subsequent disposal or reuse. The three parts of this device are smoothly connected, without wasting unnecessary labor.

[0027] Furthermore, by using vibrations of different frequencies and different screen mesh sizes in the screening device, the combined action of coarse and fine screens can separate the green peppercorns from the green peppercorn leaves and some smaller green peppercorn branches.

[0028] Furthermore, the Sichuan pepper branches and impurities are crushed in the crushing device, so that the Sichuan pepper branches do not take up a lot of space and the subsequent processing of the Sichuan pepper branches is solved. It not only achieves effective separation of impurities, but also ensures that the Sichuan pepper branches are fully crushed, which is convenient for subsequent disposal or reuse.

[0029] Secondly, this invention provides a multifunctional Sichuan pepper harvesting method based on a pile foundation. The harvesting process relies on a core mechanism—a fruit-picking device—which is achieved through the coordinated operation of three rotating shafts with different structures. The entire process, from grasping and pressing to striking, is carefully designed with optimal rotation speed and blade selection to ensure high efficiency and fruit integrity. After harvesting, the Sichuan pepper branches and pepper grains fall together into a screening device for further processing. The screening device employs a two-layer filtration design. A coarse screen performs a primary filtration to remove larger branches, while a fine screen performs a secondary filtration to remove impurities such as leaves and other small debris. These two layers of fine filtration ensure that only pure Sichuan pepper grains are ultimately collected. Simultaneously, a crank is utilized... Supported by connecting rods and powered by front and rear motors, the pure Sichuan peppercorns fall into the collection box below after screening, thus completing the entire screening process. After being filtered by the screening device, the Sichuan peppercorn branches and impurities are guided to the crushing feed box, and then slide into the blade housing for further processing. Unlike traditional sharp blades, the blades of this invention adopt an innovative design, consisting of a T-shaped blade and a baffle to achieve higher blade reliability. The T-shaped blade is responsible for cutting and crushing the Sichuan peppercorn branches and impurities, while the crushed powder leaks through the gap in the middle. Then, the baffle, through rotation, smoothly discharges the crushed powder from the outlet. This not only achieves effective separation of impurities, but also ensures that the Sichuan peppercorn branches are fully crushed, facilitating subsequent disposal or reuse.

[0073] Step 3: Start the crushing motor 53 and feed the Sichuan pepper branches and impurities into the crushing feed box 5. The Sichuan pepper branches and impurities enter the inlet of the blade housing 51 through the bottom of the crushing feed box 5. The T-shaped blade 65 cuts and crushes the Sichuan pepper branches and impurities to obtain crushed impurities. The crushed impurities pass through the arc-shaped opening 64 and the blade 61, and then are conveyed to the outlet 52 of the blade housing 51 through the baffle 66. This not only achieves effective separation of impurities, but also ensures that the Sichuan pepper branches are fully crushed, which is convenient for subsequent disposal or reuse.

[0074] To harvest Sichuan peppercorns from the stalks, this device consists of three modules: a fruit-picking device, a sieving device, and a crushing device. The fruit-picking device uses three rotating shafts to harvest the peppercorns. The sieving device, which separates impurities such as the peppercorn branches from the peppercorn grains after the fruit-picking device has finished, separates the branches and other impurities from the peppercorn grains. The crushing device crushes the branches and other impurities. This invention addresses the shortcomings of existing Sichuan peppercorn harvesting machines by designing a fruit-picking device that integrates gripping, pressing, and harvesting through different rotating shafts, which is superior to traditional clamps. The advantage of this type of harvesting mechanism lies in its higher efficiency. The screening device achieves efficient results by screening twice through screens of different sizes. Unlike traditional sharp blades, the crushing device uses high torque and high speed to achieve higher blade reliability. This design differs from other pile-based Sichuan pepper harvesting machines in that it adds the crushing of Sichuan pepper branches. The crushed Sichuan pepper branches and impurities not only do not take up much space, but can also spread the soil. Studies have shown that the crushed Sichuan pepper branches can improve soil fertility, so this device can also achieve green treatment.
