Description
Technical Field
The invention belongs to the field of crop planting production, and particularly relates to a potato harvester.
Background
The potatoes are also named as potatoes, are native to Peru and Chilean mountainous regions, are transferred to China by Dutch persons in the middle of the 17 th century, and have more than 300 years of cultivation history in China. The potato tuber contains 8-29% of starch, protein, mineral substances, vitamins and other nutrient components, has good yield and wide adaptability, and gradually becomes important food, vegetables, feed and industrial raw materials for human beings.
With the development of agricultural mechanization, a plurality of types of potato harvesting equipment exist at present, and each type of potato harvesting equipment has advantages and disadvantages, but the common problem is that the equipment can only work in sandy soil. When the potatoes growing in sandy land are harvested, sandy soil is adhered to the surfaces of the potatoes, and only screening and brushes are needed to be added to remove the soil from the sandy soil. Existing potato harvesters typically include a digging mechanism that conveys the potatoes to a screening apparatus for de-earthing after digging them out, as disclosed in patent No. CN201721254053.1 (a potato harvester) which discloses digging out the potatoes with a digging shovel and then conveying them to the screening apparatus.
However, because the universality of potato planting, the current traditional potato harvesting device only uses the brush to brush when removing soil to the potatoes in the clay soil, and the adhesion force of clay is stronger, and the soil removal degree is not high. When the potatoes are stacked, the gaps among the potatoes are reduced due to the clay, so that ventilation is not facilitated, and heating and rotting of the potatoes are accelerated.
Disclosure of Invention
The invention aims to provide a potato harvester, which aims to solve the problems that only a brush is used for brushing, the clay adhesion is strong, and the soil removal degree is not high.
In order to achieve the purpose, the basic scheme of the invention is as follows: a potato harvester comprises a rack, wherein a soil removing component is further mounted on the rack, and a digging component is used for conveying dug potatoes to the soil removing component; the soil removing assembly comprises a first conveyor belt which is obliquely arranged, a first air bag is fixed on the surface of the first conveyor belt, baffles are fixed on the two sides of the first conveyor belt on the rack, a second air bag is fixed above the baffles on the rack, the inclination directions of the second air bag and the first air bag are the same, the inclination angle of the second air bag is larger than that of the first air bag, and bristles are fixed on the surfaces of the first air bag and the second air bag; the first conveyor belt comprises a driving roller, a driven roller and a belt sleeved on the driving roller and the driven roller, a cam is rotatably connected to the middle part of the inner side of the belt on the rack, and the cam surface is abutted against the inner side of the belt; the baffle is alternately provided with an air inlet and an air outlet, the projection of the air inlet on the left baffle on the right baffle coincides with the air outlet, the projection of the air outlet on the left baffle on the right baffle coincides with the air inlet, and the hot air blower is communicated with the air inlet.
The theory of operation and the beneficial effect of this basic scheme lie in:
1. the potato gets into between first gasbag and the second gasbag from the high end of first conveyer belt, because the inclination of second gasbag and first gasbag is unanimous and the inclination of second gasbag is greater than first gasbag, and the interval between first gasbag and the second gasbag reduces gradually promptly, makes things convenient for the potato to get into between the two, and brush hair and potato contact on both are more and more inseparable simultaneously in the potato motion process, brushes down the clay of the adhesion on the potato. And the surface skin of the potatoes can not be damaged because the air bags have certain deformability.
2. The cam intermittently jacks up the upper surface of the first conveyor belt in the rotating process, so that the first air bag on the upper surface of the first conveyor belt shakes, on one hand, the distance between the first air bag and the second air bag is reduced, a certain extrusion effect is realized on potatoes, and the friction soil removal of bristles is more convenient; on the other hand, the first air bag shakes, so that clay adhered to the bristles of the first air bag can fall off conveniently.
3. Set up the baffle, on the one hand carry on spacingly to the both sides of first conveyer belt, avoid the potato to roll down, on the other hand, through the air current effect of inlet port and venthole, the potato roll is blown to gas, and the supplementary soil that takes off. The specific process is as follows: the potato is blown to the motion of being close to right side baffle venthole one side through the gas that inlet port on the left side baffle lets in, and the potato is simultaneously along with first conveyer belt motion, and the potato is close to the inlet port of right side baffle gradually, and then the gas that the inlet port of right side baffle lets in blows the potato and moves to being close to left side baffle, repeats this motion process, and the potato is the roll of snakelike route on first conveyer belt for the friction between potato and the brush hair is more abundant, is convenient for more take off earth. In addition, part of the soil can be discharged from the air outlet hole along with the action of the air flow.
4. Because the soil on the potato surface just unearthed is comparatively moist, glues easily on the surface of potato, through the hot air drying soil that the inlet port let in to can make better the droing of clod, the brush hair of being convenient for more brushes clay down.
Further, the air bag device further comprises a second conveyor belt, and the second air bag is fixed on the surface of the second conveyor belt.
Has the advantages that: the second air bag moves along with the second conveyor belt, so that the bristles can rotate out, and soil adhered to the bristles can be removed conveniently.
Furthermore, a plurality of inclined vent holes are transversely arranged on the second air bag, pressure limiting valves are arranged in the vent holes, and one side of each vent hole close to the lower end of the second air bag inclines downwards.
Has the advantages that: continuously introducing gas into the second air bag, and discharging the gas through the pressure limiting valve when the pressure in the second air bag is higher, so that the discharged gas blows off the soil adhered to the bristles, and the bristles are convenient to remove the soil; on the other hand, the gas is discharged through the inclined exhaust holes to blow the upper parts of the potatoes, so that the potatoes are overturned to a certain degree, and soil removal is more convenient.
Furthermore, a screen is arranged at the lower end of the first conveyor belt on the frame, and one end of the screen close to the first conveyor belt is abutted to the surface of the first air bag.
Has the advantages that: the potatoes move with the soil partially brushed down but still on the bristles onto a screen through which they are further sifted. And the screen is abutted against the surface of the first air bag, so that the end part of the screen can scrape the soil adhered to the first air bag.
Further, a spring is fixed between the lower end of the screen and the frame; the end face of the driving roller is fixed with a crank, the end part of the crank is hinged with a connecting rod, the end part of the connecting rod is hinged with a push rod, and the upper end of the push rod is fixed on the screen.
Has the advantages that: realize the upper and lower slip of screen cloth through slider-crank mechanism, be convenient for more sieve, drive roll and screen cloth are not located same straight line in addition, for eccentric slider-crank mechanism, have the effect of returning suddenly, and the screen cloth cooperates the inertia effect of returning suddenly at the up-and-down motion in-process, is convenient for sieve more.
