Abstract
Description
Technical Field
[0001] The present application relates to the technical field of micro-tuber sorting, and more specifically, to a sorting machine for micro-tuber harvesting. Background Art
[0002] Potato minitubers are virus-free miniature potatoes grown in isolated conditions such as greenhouses or nethouses, using either a substrate or no substrate (hydroponics or aeroponics). Because they are relatively small, typically weighing between 1 and 5 grams, they are also known as virus-free minitubers.
[0003] In related technologies, seed potatoes are categorized as original seed, original seed, and qualified seed potatoes. Miniature potatoes are classified as original seed, the highest grade of seed potatoes. During harvest, miniature potatoes need to be graded based on quality and size to facilitate subsequent batch sales. Traditionally, this is done using a rotary drum sorter with sieves.
[0004] However, in actual use, due to the large number of potato mini-tubers accumulated in the rotating drum, some potato mini-tubers cannot pass through the sieve holes to achieve size classification, thus affecting the actual sorting effect. Utility Model Content
[0005] In view of this, an embodiment of the present application provides a sorting machine for harvesting mini-potatoes to solve the problem in the related art that potato mini-tubers accumulate in a rotating drum, making it impossible to accurately sort them through the sieve holes.
[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:
[0007] A sorting machine for harvesting micro potatoes, comprising:
[0008] A frame, wherein a main guide wheel and a tail guide wheel are respectively provided on the frame through a wheel seat, a reducer and a drive motor are provided on the side of the main guide wheel, and the drive motor is connected to the main guide wheel through the reducer;
[0009] A screening barrel is tilted and arranged on the frame. The screening barrel is connected to the main guide wheel and the tail guide wheel. The screening barrel can rotate relative to the frame. The screening barrel is composed of multiple sections of round barrels. The outer wall of each section of the round barrel is provided with multiple sieve holes, and the outer diameter of the sieve holes gradually increases from high to low. Both ends of the length direction of the screening barrel are provided with arc-shaped notches.
[0010] A limit block, wherein the number of the limit blocks is multiple, the limit blocks are arranged on the inner surface of the side wall of the screening barrel, the limit block extends along the axial direction of the screening barrel, the limit block is provided with a sliding hole in the radial direction, a spring is provided in the sliding hole, a wedge block is also slidably connected in the sliding hole, the wedge block is connected to the spring, and the inclined surface of the wedge block is consistent with the inclination direction of the screening barrel;
[0011] A material blocking plate is slidably arranged in the screening barrel, and a groove portion adapted to the limit block is provided at the edge of the material blocking plate. The thickness of the material blocking plate is less than the width of the arc-shaped notch, and the material blocking plate is placed in the screening barrel through the arc-shaped notch at one end thereof;
[0012] A feed hopper, the feed hopper being located above the frame and connected to the screening barrel;
[0013] Discharge boxes, the number of which is equal to the number of the drums, are located below the screening drum, and are used to collect the micro potatoes after screening and sorting.
[0014] In some possible implementations, the spring is fixedly connected to the bottom surface of the sliding hole and the wedge block respectively.
[0015] In some possible implementations, one of the arc-shaped notches is located between the position where the screening bucket and the main guide wheel contact and the sieve hole, and the other arc-shaped notch is located between the position where the screening bucket and the tail guide wheel contact and the sieve hole.

[0020] In the sorting machine for harvesting micro-potatoes provided in the embodiment of the present application, the micro-potatoes to be sorted are poured into the screening barrel through the feed hopper, and then the main wheel is started to drive the screening barrel to rotate. At the same time, the micro-potatoes in the screening barrel will squeeze the material blocking plate to move in the screening barrel. The material blocking plate can slow down the speed of the micro-potatoes moving in the screening barrel, thereby improving the sorting effect of the micro-potatoes. In addition, when the material blocking plate contacts the wedge block, the spring will be squeezed by the wedge block and contracted.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0029] like Figures 1-4 As shown, the micro-potato harvesting and sorting machine provided in the embodiment of the present application includes a frame 100, a screening barrel 300, a limit block 400, a material blocking plate 700, a feed hopper 800, and a discharge box 900. The frame 100 is a structure for supporting the screening barrel 300. The upper end surface of the frame 100 is an inclined structure. In addition, the upper end surface of the frame 100 is respectively provided with a main guide wheel 210 and a tail guide wheel 220 through a wheel seat 200. A drive motor and a reducer for driving the main guide wheel 210 to rotate are also provided on the frame 100. The drive shaft of the drive motor is connected to the main guide wheel 210 through the reducer, and the drive motor can drive the main guide wheel 210 to rotate.
[0030] The screening bucket 300 is a container for sorting mini potatoes. It is tilted toward the upper end of the frame 100 and rotatably connected to the main guide wheel 210 and the tail guide wheel 220. Driven by a drive motor and a reducer, the screening bucket 300 rotates axially, performing sorting through mesh holes 320 formed on its outer wall.
[0031] Specifically, the screening barrel 300 is composed of multiple sections of circular barrels 310. The outer wall of each section is provided with multiple sieve holes 320. The outer diameter of the sieve holes 320 gradually increases as the screening barrel 300 tilts. In this embodiment, the outer diameter of the sieve holes 320 gradually increases from high to low. In actual use, miniature potatoes to be sorted can be poured into the upper part of the screening barrel 300, where they can be sorted according to the different sizes of the sieve holes 320 in the screening barrel 300. In addition, arc-shaped notches 330 are provided at both ends of the length of the screening barrel 300.
[0032] The inner surface of the sidewall of the screening barrel 300 is also provided with a plurality of stoppers 400. These stoppers 400 extend radially along the screening barrel 300 and have sliding holes 410 defined therein. A wedge 600 is slidably connected within the sliding hole 410, and the wedge 600 and the sliding hole 410 are connected via a spring 500. Specifically, the bottom surface of the sliding hole 410 is connected to one end of the spring 500, while the wall surface of the wedge 600 located within the sliding hole 410 is fixedly connected to the other end of the spring 500. The wedge 600 has a structure in which one wall surface is an inclined surface 610, and the inclination direction of the inclined surface 610 of the wedge 600 is aligned with the inclination direction of the screening barrel 300.
[0033] In this embodiment, a material blocking plate 700 is also slidably disposed within the screening barrel 300. The outer wall of the material blocking plate 700 is provided with a groove 710 that mates with the stop block 400 and the wedge 600. Furthermore, the thickness of the material blocking plate 700 is less than the width of the arcuate notches 330 provided at both ends of the length of the screening barrel 300. This allows the material blocking plate 700 to be installed within the screening barrel 300 through the arcuate notches 330. In some embodiments, the arcuate notches 330 are located between the main guide wheel 210 and the sieve apertures 320, and between the tail guide wheel 220 and the sieve apertures 320, respectively.
[0034] In addition, a feed hopper 800 is positioned above the frame 100 and communicates with the upper portion of the screening barrel 300. Discharge bins 900 are positioned below the screening barrel 300. The number of such bins 900 is equal to the number of drums 310. These bins 900 are used to collect the sorted miniature potatoes of varying sizes. Preferably, a discharge hopper 340 is further provided at the bottom end of the screening barrel 300 to select the largest miniature potatoes.
[0035] In the sorting machine for harvesting micro-potatoes provided in an embodiment of the present application, the micro-potatoes to be sorted are poured into the screening barrel 300 through the feed hopper 800, and then the main wheel 210 is started to drive the screening barrel 300 to rotate. At the same time, the micro-potatoes in the screening barrel 300 will squeeze the material blocking plate 700 to move in the screening barrel 300. The material blocking plate 700 can slow down the speed at which the micro-potatoes move in the screening barrel 300, thereby improving the sorting effect of the micro-potatoes. In addition, when the material blocking plate 700 contacts the wedge 600, the spring 500 will be squeezed and contracted by the wedge 600. This can further slow down the moving speed of the material blocking plate 700, thereby allowing the micro-potatoes to be fully sorted in the sieve holes 320 in the barrel 310 to improve the sorting effect.
[0036] In some embodiments, the thickness of the material blocking plate 700 is less than or equal to the width of the stop block 400, which ensures that the material blocking plate 700 can completely slide over the surface of the stop block 400, thereby ensuring smooth movement of the material blocking plate 700. In addition, the positions where the wedge block 600 contacts the stop block 400 and the material blocking plate 700 are all provided with arc surfaces 620. The provision of the arc surfaces 620 can ensure that the material blocking plate 700 can contact the wedge block 600 and the stop block 400 more smoothly, thereby reducing the material blocking plate 700 from jamming during movement.
