Description

Technical Field

[0001] The invention belongs to the field of peanut harvesting equipment, and in particular relates to a peanut harvester and method capable of intelligently cutting seedlings, crushing soil, digging and vibrating to remove soil. Background Art

[0002] With the continuous development of mechanized peanut harvesting, the research on peanut harvesting machinery in my country has entered a period of rapid development. Peanut harvesting has evolved from traditional manual digging to combined harvesting, and now to segmented harvesting with mechanical digging followed by automatic picking, which has achieved full mechanization of peanut harvesting, reduced time costs, and improved harvesting efficiency. Through continuous testing and improvement, a large number of peanut harvesting machinery have shown good adaptability in the sandy loam areas in the north, and have also gained some promotion experience. However, as one of the important peanut production areas in my country, the southern region has a large gap in the level of peanut harvesting mechanization compared with the north.

[0003] Compared with the north, the agricultural ecological climate in the southern production areas is changeable, and the geographical environment is mainly mountainous and hilly. The loam for peanut planting is mostly paddy soil, which is very different from the sandy loam in the north. The planting varieties and supporting agronomy are different. Peanut mechanical harvesting in the southern sticky soil and one ridge and two rows planting mode often encounters problems such as large northern machinery cannot operate effectively in small southern fields; peanut seedlings and weeds are mixed, blocking the digging shovel; peanuts cannot be transported normally inside the harvester and accumulate at the front end of the lifting chain; seedlings and machine parts are seriously entangled, affecting the peanut digging, soil removal and laying process; and after laying, they still need to be picked up manually and then picked. Summary of the invention

[0004] The purpose of the present invention is to provide a peanut harvester with intelligent vine cutting, soil crushing, digging and vibrating soil removal functions, so as to solve the problems of low efficiency and inconvenience in use of existing peanut harvesters.

[0005] The invention discloses a peanut harvester capable of intelligently cutting seedlings, crushing soil, digging and vibrating to remove soil, comprising:

[0006] The main frame is provided with ground wheels on the sides; the power box provides power for the soil crushing and excavation device and the conveying chain.

[0007] The seedling cutter is connected to the main frame through a connecting frame; the seedling cutter includes a slide bar frame, a motor support frame, a crank slider mechanism and a 588-type reciprocating cutter, the slide bar frame is connected to the connecting frame, the motor support frame is arranged on the slide bar frame, the 588-type reciprocating cutter is installed on the slide bar frame, and a cutting driver is arranged on the motor support frame, and the cutting driver is connected to the 588-type reciprocating cutter through a crank slider mechanism to achieve cutting action. The slide bar frame and the connecting frame are slidably matched to adjust the height of the seedling cutter; the slide bar frame fixes the slide bar in the connecting frame through a locking bolt.

[0008] The soil-crushing and digging device is installed on the main frame and is located behind the seedling cutter. The soil-crushing and digging device includes a digging mechanism and a soil-crushing mechanism. The digging mechanism includes a digging shovel, which is connected to the main frame. The soil-crushing mechanism includes a reducer, a gearbox, a coupling, a right-angle transmission, a rotating shaft, a soil-crushing squeezing rod, a soil-crushing separation grid and a support rod. The soil-crushing separation grid is connected to the digging shovel. The rotating shaft passes through the soil-crushing squeezing rod. The rotating shaft is connected to the right-angle transmission. The right-angle transmission is connected to the power box through the coupling, the gearbox and the reducer in sequence. A displacement controller is provided on the soil-crushing squeezing rod, and a pressure sensor is provided on the first displacement controller. The pressure sensor detects the pressure of the support rod on the first displacement controller. The soil-crushing squeezing rod includes a short tooth of the soil-crushing squeezing rod, and a force sensor is provided inside the short tooth of the soil-crushing squeezing rod. The force sensor is used to detect the digging resistance of the digging shovel. It cooperates with the pressure sensor. When the pressure and resistance change trends are the same, the two adjust the height of the soil-crushing squeezing rod through the first displacement controller.

[0009] The conveyor chain is rotatably mounted on the main frame and is located behind the soil crushing and excavation device; the conveyor chain includes a conveyor transmission chain, a conveyor chain plate and a tensioning device, the conveyor chain plate is arranged on the conveyor transmission chain, and the tensioning device is connected to the transmission chain and is used to adjust the tension of the conveyor transmission chain. The conveyor chain plate is provided with triangular spurs.

[0010] The shaking soil removal device is connected to the conveyor chain; the shaking soil removal device includes a support plate, a latch shaft, a vibrating wheel, a support shaft and a position regulator, the support shaft is connected to the main frame, the vibrating wheel is installed on the support plate through the latch shaft, the vibrating wheel is in contact with the conveyor chain plate, and the position regulator is connected to the vibrating wheel. A pressure sensor is installed inside the vibrating wheel, and the position regulator includes a second displacement controller and a telescopic mechanism, and the height and telescopic length of the telescopic mechanism are controlled by the second displacement controller according to the pressure sensor information.

[0011] The peanut collecting platform is arranged at the rear end of the conveyor chain and is used for collecting the harvested peanuts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Compared with the traditional two-stage harvester, this harvester divides the segmented harvesting into three stages: peanut seedling cutting, soil crushing and digging, and vibration fruit-soil separation. In addition, because a soil crushing and squeezing stick is installed above the digging, this machine has stronger adaptability than the traditional segmented harvester in the southern rice fields with high soil viscosity.

[0014] Compared with the traditional segmented harvester, this harvester is equipped with a seedling cutter, so that the cut seedlings can be used as feed, reducing the breeding cost, and the cut peanuts can be picked by the fruit picking machine without drying, effectively reducing time and labor costs. The seedling cutting height can be adjusted, and seedlings and weeds of a certain height can be cut off to improve the harvest quality and reduce the phenomenon of seedlings and machinery entanglement.

[0015] This harvester can dig peanuts and break large soil blocks through the soil crushing and digging device to solve the problem that the soil in the south is sticky and difficult to dig and break. The soil crushing and squeezing rod is driven by the power box to rotate. The speed of the squeezing and crushing rod can be adjusted by manually adjusting the small gear reducer to prevent the speed from being too high and damaging the peanuts and the roots of the plants, so as to adapt to soils of different types, viscosities, humidity and compaction degrees. The soil crushing and digging device is equipped with an automatic height regulator, which includes a pressure sensor, a force sensor, and a displacement controller. The pressure sensor detects the pressure of the support rod on the displacement controller, the force sensor detects the digging resistance of the digging shovel, and the controller adjusts the squeezing force by adjusting the squeezing height of the soil crushing squeezing roller. When the digging resistance and pressure increase (or decrease) at the same time, the controller controls the soil crushing squeezing roller to descend (or rise), and the controller controls the roller teeth to always insert into the soil of different compaction degrees through feedback from the displacement sensor. The speed of the soil crushing roller can be automatically adjusted with the operating vehicle speed, and its rotational linear speed is 1.X times faster than the vehicle speed to pry the soil backward.

[0016] This harvester can solve the problem of difficult separation of fruit and soil during mechanical peanut harvesting in the south through a conveyor chain and a shaking soil removal device. The shaking soil removal device is equipped with a vibration amplitude and frequency regulator, which is composed of multiple vibration wheels. The spacing and overall height of the vibration wheels are automatically adjusted. A pressure sensor is installed inside the vibration wheel. The pressure sensor detects the pressure of the conveyor chain steel plate in real time. When the amount of peanut plants transported by the conveyor chain increases, the pressure on the steel plate increases (or decreases), and the pressure of the steel plate on the vibration wheel increases (or decreases). When the pressure changes too much (or the pressure changes too little), the displacement controller controls the telescopic mechanism to reduce (increase) the spacing between the vibration wheels and increase (lower) the overall height of the vibration wheels, thereby increasing (decreasing) the vibration frequency and amplitude.

[0017] A peanut collecting platform is installed at the rear end of the harvester. The peanuts after being cut can be directly dropped onto the peanut collecting platform after being shaken and soil removed by the conveyor chain. The collecting platform can be used to place baskets and bags to directly collect the peanuts, without the need for subsequent manual picking, thus reducing labor costs and improving efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 3 As shown, the intelligent peanut harvester for cutting seedlings, crushing soil, digging and vibrating soil removal of this embodiment includes: a main frame 1, with ground wheels 11 on the side; a seedling cutter 4, connected to the main frame 1 through a connecting frame 2; a soil crushing and digging device 8, installed on the main frame 1, and located behind the seedling cutter 4; a conveyor chain 9, rotatably installed on the main frame 1, and located behind the soil crushing and digging device 8; a shaking soil removal device 10, connected to the conveyor chain 9; and a peanut collecting platform 12, arranged at the rear end of the conveyor chain 9.

[0035] like Figure 4 As shown, the seedling cutter 4 includes a slide bar frame 4-1, a motor support frame 4-2, a crank slider mechanism 4-3 and a 588 type reciprocating cutter 4-4. The slide bar frame 4-1 is connected to the connecting frame 2, the motor support frame 4-2 is arranged on the slide bar frame 4-1, the 588 type reciprocating cutter 4-4 is installed on the slide bar frame 4-1, and a cutting driver 3 is arranged on the motor support frame 4-2. The cutting driver 3 is connected to the 588 type reciprocating cutter 4-4 through the crank slider mechanism 4-3 to achieve the cutting action. The slide bar 4-1 and the connecting frame 2 are slidably matched, and the slide bar 4-1 is fixed in the connecting frame 2 by a locking bolt. In this way, the seedling cutting height can be adjusted, and the seedlings and weeds of a certain height can be cut off to improve the harvest quality and reduce the phenomenon of seedlings and tools being entangled.

[0036] The slide bar frame 4-1 is provided with a baffle 13, which is a V-shaped structure, and the cut seedlings are dispersed on the left and right sides. The cutting driver 3 is a BMR-125 hydraulic motor, the seedling cutter 4 has an operating width of 700mm, and the installation height is 100mm-300mm above the ground. When the machine is operating, the reciprocating knife of the seedling cutter 4 can cut the peanut seedlings, and at the same time, the shaking soil removal device 10 inside the conveying chain 9 makes the seedlings fall from the gap between the chain plates during transportation, so that the peanut seedlings are effectively separated from the roots.

[0037] like Figure 5As shown, the soil crushing and digging device 8 includes a digging mechanism and a soil crushing mechanism. The digging mechanism includes a digging shovel 8-6 ​​and a soil crushing separation grid 8-10. The digging shovel 8-6 ​​is connected to the soil crushing separation grid 8-10, and the digging shovel 8-6 ​​is connected to the main frame 1. While digging peanuts, the soil crushing mechanism squeezes and crushes large soil blocks, and the crushed soil blocks are separated by the soil crushing separation grid 8-10. The digging shovel 8-6 ​​is connected to the fixing seat 7, and the installation height of the digging shovel 8-6 ​​can be adjusted. The soil crushing mechanism includes a reducer 8-1, a gearbox 8-2, a coupling 8-3, a right-angle transmission 8-4, a rotating shaft 8-7 and a soil crushing squeezing rod 8-5.

[0038] The soil crushing separation grid 8-10 and the digging shovel 8-6 ​​are connected by welding, with an inclination angle of 25°, an internal cutting angle of 24°, and an installation clearance of 32.5mm for the soil crushing separation grid 8-10. The digging shovel 8-6 ​​is connected to the fixing seat 7 by bolts, and the installation height of the digging shovel 8-6 ​​can be adjusted by tightening the bolts. The soil crushing squeezing rod 8-5 is driven by the output shaft of the power box 6, and its operating width is 600mm. During operation, the digging shovel 8-6 ​​scoops up all the soil and peanuts at the bottom of the ridge, and the soil crushing squeezing rod 8-5 crushes the soil blocks generated during the excavation process, and makes the soil blocks fall to the ground through the soil crushing separation grid 8-10 during transportation. The digging shovel 8-6 ​​is connected to the fixing seat 7 by bolt tensioning. There are nuts welded on both sides of the fixing seat 7. When the bolts are tightened, the digging shovel 8-6 ​​is pressed against the inner wall of the fixing seat. At this time, the height cannot be adjusted, and the digging height of the digging shovel is fixed. When the bolts are loosened, the digging shovel 8-6 ​​can adjust the height. The soil crushing and squeezing rod 8-5 is installed on the main frame 1 through a support rod 8-11, and a first displacement controller 8-8 is provided on the support rod 8-11, and a pressure sensor 8-9 is provided on the first displacement controller 8-8.

[0039] like Figure 6As shown, the soil crushing squeezing roller 8-5 includes a soil crushing squeezing roller short tooth 8-5-1, and a force sensor 8-5-2 is arranged inside the soil crushing squeezing roller short tooth 8-5-1. The force sensor 8-5-2 detects the digging resistance of the digging shovel, and adjusts the height of the soil crushing squeezing roller 8-5 through the first displacement controller 8-8. The pressure sensor 8-9 and the first displacement controller 8-8 are fixed to the main frame 1. The pressure sensor 8-9 detects the pressure of the support rod 8-11 on the first displacement controller 8-8. The force sensor 8-5-2 is fixed inside the soil crushing squeezing roller 8-5. The force sensor 8-5-2 detects the digging resistance of the digging shovel 8-6. The first displacement controller 8-8 adjusts the squeezing force by adjusting the squeezing height of the soil crushing squeezing roller 8-5. During the operation of the harvester, when the digging resistance and the pressure on the first displacement controller 8-8 increase (or decrease) at the same time, the first displacement controller 8-8 controls the soil crushing squeezing roller 8-5 to descend (or rise), and the first displacement controller 8-8 controls the roller teeth to always insert into the soil with different degrees of compaction. The rotation speed of the soil crushing and squeezing roller 8-5 can be automatically adjusted with the operating vehicle speed, and its rotational linear speed is 1.X times faster than the vehicle speed to loosen the soil backward; wherein X is a natural number, X≥0.

[0040] like Figure 7 As shown, the conveyor chain 9 includes a conveyor transmission chain 9-1, a conveyor chain plate 9-2 and a tensioning device 9-4.

[0041] like Figures 8 to 10 As shown, the shaking soil removal device 10 includes a support plate 10-2, a latch shaft 10-1, a vibration wheel 10-3, a support shaft 10-4 and a position regulator 10-5, the support shaft 10-4 is connected to the main frame 1, the vibration wheel 10-3 is installed on the support plate 10-2 through the latch shaft 10-1, the vibration wheel 10-3 is in contact with the conveying chain plate 9-2, and the position regulator 10-5 is connected to the vibration wheel 10-3. A pressure sensor 10-3-1 is installed inside the vibration wheel 10-3.

[0042] Support plates 10-2 are installed on both sides of the support shaft 10-4, and three latch shafts 10-1 are arranged inside the support plate 10-2. The vibration wheel 10-3 is installed on the latch shaft 10-1, and the vibration wheel 10-3 is connected to the position regulator 10-5 through the latch shaft 10-1. When the machine is in operation, the conveying chain plate 9-2 collides with the vibration wheel 10-3, and the vibration wheel 10-3 is brought to its vertex. At this time, the conveying chain plate 9-2 vibrates, and the vibration amplitude and vibration frequency are adjusted by the vibration amplitude and position regulator 10-5. The shaking soil removal device 10 shakes off the soil carried by the peanut roots and pods in the form of the internal vibration wheel 10-3 colliding with the conveying chain plate 9-2.

[0043] The shaking soil removal device 10 is provided with a vibration amplitude and position regulator 10-5. The position regulator 10-5 includes a second displacement controller 10-5-1 and a control telescopic mechanism 10-5-2 composed of multiple vibration wheels 10-3. The spacing and overall height of the vibration wheels 10-3 are automatically adjusted. A pressure sensor 10-3-1 is installed inside the vibration wheel. The pressure sensor detects the pressure of the conveying chain plate 9-2 in real time. When the amount of peanut plants conveyed by the conveying chain 9 increases, the pressure on the conveying chain plate 9-2 increases (or decreases). The conveying chain plate 9-2 increases (or decreases) the pressure on the vibration wheel 10-3. When the pressure change is too large (or the pressure change is too small), the second displacement controller 10-5-1 controls the telescopic mechanism 10-5-2 to reduce (increase) the spacing between the vibration wheels 10-3 and increase (lower) the overall height of the vibration wheel 10-3, thereby increasing (decreasing) the vibration frequency and amplitude.

[0044] A power box 6 is installed in the middle of the front end of the main frame 1. The left output shaft of the power box 6 is connected to the conveying chain 9 through the first transmission chain 5, driving the conveying chain 9 to move. The rotating shaft 9-7 is installed on the main frame 1. The shaft sleeve 9-6 is rotatably sleeved outside the rotating shaft 9-7. A sprocket 9-5 is arranged on the rotating shaft 9-7. The conveying transmission chain 9-1 is meshed with the sprocket 9-5. The first transmission chain 5 drives the sprocket 9-5 to rotate, and then drives the conveying transmission chain 9-1 to rotate. The right output shaft of the power box 6 is connected to the gearbox 8-2 through the planetary reducer 8-1. The gearbox 8-2 is connected to the soil crushing extrusion rod 8-5 through the coupling 8-3. The bottom of the soil crushing extrusion rod 8-5 is provided with an excavating shovel 8-6, and the excavating shovel 8-6 ​​is connected to the fixed seat 7.
