Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural harvesting machinery, and in particular relates to a wind-blown fruit picking structure for picking up fruits dropped on the ground and a fruit picking machine using the structure. Background Art

[0002] Peanuts are currently cultivated across a wide area in China. Before harvest, they need to be laid out in strips to dry. During harvest, some of the dried peanuts naturally fall to the ground, which large harvesters cannot pick up. Manual collection is time-consuming and laborious for farmers with small planting areas, while farmers with large planting areas lack the energy for manual collection. This results in a significant waste of resources and hinders the rush to harvest in autumn. Other crops also face the problem of manual collection being time-consuming and labor-intensive.

[0003] Therefore, a new technical solution is urgently needed in the existing technology to solve this problem. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wind-blown fruit picking structure and a fruit picking machine using the structure to solve the technical problem in the prior art that manually picking up fruits that have fallen on the ground is time-consuming and labor-intensive.

[0005] A wind-blown fruit picking structure comprises a picking roller and a fruit blowing fan. A row of multiple tightly arranged flexible fruit blocking strips is fixedly installed on the lower edge of the fruit inlet of the picking roller; the air outlet of the fruit blowing fan is located on the fruit inlet side of the picking roller.

[0006] A fruit picking machine, using the aforementioned wind-blown fruit picking structure, comprises a main frame with wheels, a debris removal mechanism, an elevator, and a fruit storage box, wherein the main frame with wheels is connected to an external four-wheeled vehicle; the discharge port of the debris removal mechanism is connected to the feed port of the elevator; the discharge port of the elevator is located above the fruit storage box; the machine further comprises a wind-blown fruit picking structure, spring teeth, and a spline transmission shaft mounted on the main frame; the spring teeth are mounted on the lower front end of the main frame with wheels via an adjustment mechanism; the picking roller is located behind the spring teeth, and the fruit discharge port of the picking roller is connected to the feed port of the debris removal mechanism;

[0007] The spline drive shaft is connected to the output shaft of the diesel engine or the output shaft of the four-wheel vehicle through a universal joint drive shaft as power input; the input shaft end sprocket of the speed change reversing box assembly is connected to the output sprocket of the spline drive shaft, and the output shaft of the speed change reversing box assembly, the output sprocket of the spline drive shaft, the drive shaft of the wind-blown fruit picking structure, the drive shaft of the impurity removal mechanism and the lifting main shaft of the elevator are connected through pulleys or transmission chains as corresponding power inputs.

[0008] Brushes are evenly arranged on the rotating shaft of the picking roller.

[0009] A counterweight block is fixedly mounted on the upper outer edge of the flexible fruit blocking strip.

[0010] The spring teeth are provided in two rows, and the two rows of spring teeth are arranged in sequence from front to back along the forward direction of the main frame.

[0011] The impurity removal mechanism includes a vibrating screen and a vertical impurity removal fan; the vibrating screen is installed on the fruit outlet side of the picking roller, and the outlet of the vibrating screen is connected to the feed port of the elevator; the vertical impurity removal fan is arranged on the upper part of one side of the vibrating screen.

[0012] The elevator adopts a double-row skimmer lifting structure.

[0013] Through the above design scheme, the present invention can bring the following beneficial effects:

[0014] This invention is a collection device specifically designed for peanuts and other fruits that have fallen from vines. The spring tines, which are raised or lowered by an adjustment mechanism, adjust the depth of their penetration into the soil. This lifts fallen peanuts or those buried shallowly out of the ground, placing them above the surface and making them easier for the collection device to retrieve. A collection roller and a fruit blower are mounted at the rear end of the spring tines. The fruit blower blows the peanuts off the ground into the collection roller. The collection roller's structure is completely different from that of traditional peanut harvesters. A brush mounted on the roller sweeps the peanuts into a vibrating screen for dust removal. A vertical dust removal fan removes weeds and other debris. After dust removal, an elevator collects the peanuts using a double row of skimmers and transfers them to a storage bin.

[0015] A flexible fruit retaining bar is installed at the lower end of the fruit inlet of the picking roller, and a counterweight is installed at the lower end of the flexible fruit retaining bar. This novel and unique design allows the flexible fruit retaining bar to adhere tightly to uneven ground, ensuring that all peanuts on the ground are blown into the roller along the flexible fruit retaining bar. The present invention has a simple structure and is easy to operate. It has a high pickup rate and no peanuts are lost. It can save a lot of manpower, improve the efficiency of autumn harvesting, and avoid the waste caused by not being able to pick up fallen peanuts. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] As shown in the figure, a wind-blown fruit picking structure includes a picking roller 4 and a fruit blowing fan 5, and its characteristics are: a row of multiple tightly arranged flexible fruit blocking strips 403 are fixedly installed on the lower edge of the fruit inlet of the picking roller 4; the air outlet of the fruit blowing fan 5 is located on the fruit inlet side of the picking roller 4; the flexible fruit blocking strip 403 is a strip structure made of wear-resistant and flexible material such as rubber strips, so as to ensure that no matter whether it is a ridge, a ridge or a pit, the lower edge of the flexible fruit blocking strip 403 can be in contact with the ground surface, so that the peanut fruit can smoothly enter the picking roller 4 under the blowing of the fruit blowing fan 5.

[0039] A fruit picking machine using a wind-blown fruit picking mechanism includes a main frame 1 with wheels, spring teeth 2 and a splined drive shaft 3, picking rollers 4, a fruit blower 5, a debris removal mechanism, an elevator 6, and a fruit storage box 7. The wheeled main frame 1 is connected to an external four-wheeled vehicle. The main frame 1 is a welded frame with a compact structure. Two rows of spring teeth 2 are mounted at the front lower end of the main frame 1. The two rows of spring teeth 2 are arranged sequentially from front to back along the forward direction of the main frame 1. The spring teeth 2 are equipped with adjustment mechanisms to adjust the rise or fall of the spring teeth 2, thereby adjusting the depth of penetration into the soil. This allows peanuts that have fallen on the ground or are buried shallowly to be lifted out of the ground and placed above the ground. The picking rollers 4 and the fruit blower 5 are mounted in sequence at the rear end of the spring teeth 2.

[0040] The impurity removal mechanism includes a vibrating screen 9 and a vertical impurity removal fan 10. One end of the picking roller 4 is provided with a fruit inlet, which faces the air outlet of the fruit blowing fan 5. The other end of the picking roller 4 is a fruit outlet, which is connected to the vibrating screen 9. The vertical impurity removal fan 10 is arranged on the upper part of one side of the vibrating screen 9. The feed port of the elevator 6 is connected to the discharge port of the vibrating screen 9. Brushes 402 are evenly arranged on the rotating shaft 401 of the picking roller 4. The lower edge of the fruit inlet of the picking roller 4 is provided with a row of multiple tightly arranged flexible fruit blocking strips 403; the upper outer edge of the flexible fruit blocking strips 403 is fixedly installed with a counterweight block 404 to further ensure the fit with the ground. The fruit blowing fan 5 blows the peanuts into the picking roller 4, and uses the brush 402 installed on the rotating shaft 401 to collect them into the impurity removal mechanism for impurity removal, and then transmits them to the elevator 6. The discharge port of the elevator 6 is located at the upper part of the fruit storage box 7. The elevator 6 adopts a double-row skimming spoon lifting structure with high lifting efficiency. The elevator 6 collects the picked peanuts into the fruit storage box 7.

[0041] The spline drive shaft 3 is connected to the diesel engine output shaft or the four-wheel vehicle output shaft via a universal joint drive shaft as the power input. A double sprocket I 301 is mounted on the spline drive shaft 3. The double sprocket I 301 is connected to the double sprocket II 801 at one end of the speed change reversing case assembly 8 via a drive chain, serving as the power input to the speed change reversing case assembly 8. The output end of the speed change reversing case assembly 8 is equipped with a single sprocket I 802 and a pulley I 803.

[0042] The pulley I 803 drives the eccentric shaft pulley 901 on the vibrating screen 9 to rotate through a belt, causing the vibrating screen 9 to vibrate.

[0043] The single sprocket I802 is connected to the single sprocket II405 installed on the rotating shaft 401 through a transmission chain. The rotation of the single sprocket II405 drives the pulley II406 on the rotating shaft 401. The pulley II406 drives the rotating shaft I501 of the fruit blower 5 through a belt drive, and the fruit blower 5 rotates to blow air.

[0044] The rotation of the single sprocket II 405 drives another pulley III 407 on the rotating shaft 401. The pulley III 407 drives the rotating shaft II 1001 of the vertical impurity removal fan 10 to rotate at a high speed through a belt transmission, and the vertical impurity removal fan 10 rotates and blows air.

[0045] The rotation of pulley III 407 drives pulley IV 408, which is coaxially mounted with pulley III 407. Puller V 11 is mounted on the main frame 1 via a bearing at the bottom of pulley IV 408. Pulley IV 408 and pulley V 11 are driven by a belt. Sprockets are installed on one side of the bearing connecting pulley V 11 and on one side of the hoisting main shaft 601 of the hoist 6. These two sprockets and a chain fastened to the outside of the two sprockets form a coupling, connecting the bearing connecting pulley V 11 to the hoisting main shaft 601 of the hoist 6, providing lifting power for the hoist 6.
