As shown in fig. 1-5, the present utility model provides a power buoy for a potato harvester, wherein the potato harvester includes an excavating assembly and a loading assembly 100, and a power buoy 200 is disposed above the front side of the excavating assembly. In use, the digging assembly digs up soil and potatoes which are continually transported to the feeding assembly 100 as the potato harvester is continually advanced. Along with the fact that soil and potatoes are continuously conveyed to the feeding assembly 100, under the action of friction force between the soil excavated by the excavating assembly and the power pontoon 200, the soil excavated by the excavating assembly pushes the power pontoon 200 to rotate, and under the combined action of the power pontoon 200, the soil power pontoon excavated by the excavating assembly is crushed, so that the purpose of automatically separating soil from potatoes on the feeding assembly 100 is achieved.
In the present utility model, power buoy 200 includes a cylinder 210 and a crushing plate 220.
The cylinder 210 is cylindrical, and the outer diameter of the cylinder 210 is R 2 Wherein 200mm is greater than or equal to R 2 And is more than or equal to 160mm. Although the larger the cylinder 210 is, the better the rolling effect on the soil is, since the larger the radius of the cylinder 210 is, the larger the weight of the cylinder 210 is, and thus, preferably, R 2 =180 mm. The cylinder is rotationally connected with a frame of the potato harvester. The number of the rolling plates 220 is m, and m rolling plates 220 are installed on the side wall of the cylinder 210 around the axial lead of the cylinder 210 and fixedly connected with the cylinder 210, wherein m is more than or equal to 4. In order to improve the rolling effect on the soil, it is preferable that m rolling plates 220 are uniformly disposed around the axis of the cylinder 210 and the width direction of the rolling plates 220 extends in the radial direction of the cylinder 210. Although the greater the number of crushing plates 220, the better the crushing effect on the soil, as the number of crushing plates 220 increases, the angle between two adjacent crushing plates 220 becomes smaller, which results in soil and/or potatoes being caught between two adjacent crushing plates 220, and thus, preferably, m=6.
When the potato harvester is used, the power pontoon 200 is rotatably arranged above the front side of the digging assembly of the potato harvester, the digging assembly fully scoops up potatoes and soil on ridges along with forward pushing of the harvester, and the soil is crushed under the combined action of the digging assembly and the power pontoon 200, so that the purpose of facilitating automatic separation of the soil and the potatoes on the feeding assembly 100 is achieved.
According to the utility model, by arranging the rolling plate 220, under the action of the rolling plate 220, the soil excavated by the excavating component can be cut and rolled along with the rotation of the power pontoon 200, so that the soil crushing effect is improved, and meanwhile, along with the rotation of the power pontoon 200, the rolling plate 220 can stir the soil excavated by the excavating component and potatoes towards the feeding component 100, so that the aim of improving the feeding effect is fulfilled.
In order to reduce the risk of damage to the potatoes by the platen 220, it is preferable that the side of the platen 220 remote from the axis of the barrel 210 be arcuate.
In one embodiment, both ends of the cylinder 210 are provided with blocking rings 230, and the outer walls of the blocking rings 230 are located outside the rolling plate 220. Specifically, the blocking ring 230 is disposed coaxially with the cylinder 210. By providing the blocking rings 230 at both ends of the cylinder 210, the purpose of preventing the excavated soil and potatoes of the excavating assembly from flowing out from both ends of the recess defined by the rolling plate 220 and the cylinder 210 is achieved.
In one embodiment, the sidewalls of the opposite sides of the two blocker rings 230 have an included angle α, where 60+.α+.120 °. I.e., the side walls of the opposite sides of the two blocking rings 230 are gradually closed toward the axis of the cylinder 210. The opposite side walls of the two blocking rings 230 have an included angle α, so that the soil excavated by the excavating assembly can be extruded by using the opposite side walls of the two blocking rings 230, thereby achieving the purpose of further improving the rolling effect on the soil. Preferably, α=80°.
In one embodiment, both ends of power buoy 200 are provided with grooves 240. By providing grooves 240 at both ends of power buoy 200, the weight of the entire power buoy 200 can be reduced. Preferably, the groove 240 is spherical.
In one embodiment, the width of the platen 220 is L and the outer diameter of the blocker ring 230 is R 1 The outer diameter of the cylinder 210 is R 2 Wherein 200mm is greater than or equal to R 2 160mm, if the difference between the outer diameters of the blocking ring 230 and the barrel 210 is larger, it means that the groove formed by surrounding the blocking ring 230, the barrel 210 and the rolling plate 220 is deeper, which is very easy to cause soil and potatoes to be stuck inside, and if the difference between the radii of the blocking ring 230 and the barrel 210 is too small, the potatoes are very easy to be crushed, so that the difference between the radii of the blocking ring 230 and the barrel 210 satisfies the formula: r is 110mm or less 1 -R 2 And the thickness is less than or equal to 130mm. Likewise, if the platen 220 is too wide, it is very easy to grind or load potatoes with the platen 220, and if the platen 220 is too small in width, the soil is ground more effectivelyAccordingly, the width L of the platen 220 satisfies the relationship: preferably, R 1 ＝300mm，R 2 ＝180mm，L＝80mm。
In one embodiment, the potato harvester further comprises a driving device, wherein the power output end of the driving device is in transmission connection with the power input end of the power pontoon, the driving device is used for driving the barrel 210 to rotate, the moving direction of the lowest part of the barrel 210 is opposite to the advancing direction of the potato harvester, and the moving direction of the lowest part of the barrel 210 is opposite to the advancing direction of the harvester, so that the rolling plate 220 can have the effect of stirring soil and potatoes upwards of the feeding assembly 100.
According to the power pontoon provided by the utility model, the driving device is arranged to drive the barrel 210 to actively rotate instead of enabling the barrel 210 to passively rotate under the action of soil, so that the purpose of improving the grinding effect of the power pontoon on the soil is achieved, and the stirring efficiency of the rolling plate 220 on the soil and potatoes is improved.
Specifically, the drive means comprises an electric motor comprising a stator 250 and a rotor 260. The stator 250 is coaxially inserted into the cylinder 210 and is rotatably connected with the cylinder 210, the stator 250 is fixedly connected with the frame, and specifically, both ends of the rotor 260 are fixedly connected with the frame. The rotor 260 is coaxially inserted into the cylinder 210 and fixedly connected with the cylinder 210, and the rotor 260 is coaxially sleeved on the stator 250.
The driving device with the structure has simple and compact structure and reasonable design.
